A female patient R.N.N. F, age 66, from the city of Manaus, with a previous diagnosis of Sjogren’s syndrome in regular follow-up by the Rheumatology team at the Araujo Lima outpatient clinic and referred to the Ophthalmology sector for complementary evaluation related to visual discomfort. The fundoscopy performed in the patient was within normal limits, but the symptoms experienced by her proved to be an important clinical finding, which has ratified the need for regular and multidisciplinary follow-up. This report unequivocally demonstrates that even in the face of tests considered within the expected limits for a given population, the clinical presentation can be specific and particular for each analyzed individual. Early screening exams should contemplate the patient in a holistic and individualized way whenever possible.展开更多

The aim of this study is to evaluate the prevalence of MS in a cohort of patients with RA and its correlation to specific factors of the disease. A retrospective cohort study was conducted with 283 patients with RA, followed at the Rheumatology Outpatient Clinic of the Hospital de Clínicas de Porto Alegre (HCPA) between 2008 and 2016;187 continued to be followed and agreed to be reevaluated between January and November 2016. MS was defined according to the National Cholesterol Education Program and disease activity was assessed using the Disease Activity Score (DAS28). Clinical, biochemical, and anthropometric evaluations were conducted. The prevalence of MS in the first evaluation was 43.9% and, after 8 years, 59.4%. Increased waist circumference and blood pressures, elevated triglycerides and low High-Density Lipoprotein were the most frequent features of MS. The DAS28 was significantly lower in the reevaluation (p = 0.006). The prevalence of MS was higher at the end of 8 years;disease activity, as well as blood pressure, decreased during this period. Steroid use had also decreased at the end of follow-up. There was an increase of 15% of cases with MS in an 8-year follow-up cohort of patients, which was in agreement with the current literature and showed how the inflammatory process in RA is correlated to MS. The parameters of MS that varied the most were blood pressure, cholesterol and triglycerides. Ultimately, these parameters and disease activity must be observed closely in order to improve the prognosis of patients with RA.展开更多

However, these studies may be compromised, if the results compared to a placebo or standard therapy group (in the absence of a placebo) substantially differ from the expected response. In addition, significant concerns have been raised regarding the reliability and validity of the CDAI. Reproducibility of the CDAI may be limited as significant inter-observer error has been recorded, even if measurements are done by experienced clinicians with expertise in the diagnosis and treatment of CD. Finally, many CDAI endpoints are open to subjective interpretation and have the potential for manipulation. This is worrisome as there is the potential for significant financial gain, if the results of a clinical trial appear to provide a positive result. Physicians caring for patients should be concerned about the positive results in clinical trials that are sponsored by industry, even if the trials involve respected centers and the results appear in highly ranked medical journals.展开更多

It is characterized by lymphocytic infiltration of lacrimal and salivary glands and autoantibody production, especially anti-Ro (or SSA) and anti-La (or SSB). Lymphoproliferative disorders are a feature of Sjogren’s syndrome, and can be considered an extraglandular manifestation of the disease. Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a rare form of lymphadenitis. It is reported more often in young adult women with localized lymphadenopathy (usually cervical), fever, rashes, and leukopenia. It is a self-limiting disease with resolution within 1 - 4 months in almost all patients. Sjogren’s syndrome has been reported in patients with other systemic diseases including SLE and lymphomas. Here we present a patient with Kikuchi-Fujimoto disease who developed Sjogren’s Syndrome 8 years after her diagnosis of Kikuchi-Fujimoto disease.展开更多

Objectives: To test the patients’ knowledge about their disease, its treatment, its complications, and if this affects severity of the disease as measured by the disease activity index (DAS 28). Patients and Methods: A sample of 100 patients with RA who met the Criteria of American College of Rheumatology for RA agreed to participate in this study over the period September 2011-March 2012. Patients’ data were obtained by personal interview. The questionnaire included demographic characteristics and the patients’ knowledge about their disease. The disease activity was measured using standard (DAS28). Results: Thirty three percent of the patients didn’t have an idea about their disease, 20% didn’t know the reason for the investigations, 49% didn’t know the treatment and 40% didn’t know the side effects of their medications. Most patients had a high disease activity index, and there was a poor correlation between patients’ educational level and the disease activity. Conclusions: Neither the educational level nor the frequency of hospital admissions had effects on the knowledge about this disease. As most patients had a high disease activity, a better knowledge may improve disease control and prevent complications.展开更多

It is characterised by fat necrosis, chronic inflammation and fibrosis, causing thickening and shortening of the mesentery. Patients may present with localised abdominal pain, abdominal mass, intestinal obstruction and ischaemic colitis. We report a case of mesenteric panniculitis causing abdominal pain in a patient with active Primary Sjogren’s Syndrome. The rarity of this case makes it of interest. We review the current literature on mesenteric panniculitis and its association with connective tissue disease and inflammatory conditions. A 64-year-old Caucasian male presented in 1994 with dry mouth. A diagnosis of Primary Sjogren’s Syndrome (PSS) was made on salivary gland biopsy. In 2010 he presented with an exacerbation of his eye symptoms, muscle pain and fatigue. He complained of abdominal pain and night sweating, but denied any weight loss or change in bowel habit. There was no significant past medical history other than PSS. On examination he had a small right submandibular node and mild synovitis at the right proximal interphalangeal joint and carpometacarpal joint. Examination of the abdomen showed marked umbilical tenderness but no organomegally. Blood tests at this time showed an active inflammation: CRP of 61 (NR 5 mg/L), ESR 39 (NR 20 mm/s), strongly positive ENA Ro and La. IgG was elevated at 18.6 (NR 5.8-15.4), Complement was low at 0.17 (NR 0.18-0.6). An abdominal ultrasound scan demonstrated a 6 × 3 ×3 cmarea of diffuse homogenous fat encasing some mesenteric vessels in the area of focal tenderness. CT abdomen and pelvis showed oedematous mesenteric fat and lymph nodes in the jejunal small bowel mesentery, consistent with mesenteric panniculitis. Laparoscopic biopsy was discussed with the surgical team, but was felt not indicated as risk outweighed potential benefit. The patient was treated with a 9-week reducing course of oral steroids. His abdominal symptoms resolved although CT abdomen showed little improvement in mesenteric panniculitis. A review of the literature suggests that currently there is no standard treatment and management should be guided by patient symptoms. Mesenteric Panniculitis is rare;as a result evidence for treatment is limited to individual case reports. There is no clear link between symptom improvement and radiological resolution of mesenteric panniculitis. It has, therefore been suggested that follow-up imaging should be limited to those with persistent symptoms. Overall the prognosis for mesenteric panniculitis is good, up to half of patients do not require treatment, and recurrence of symptoms is uncommon.展开更多

METHODS: One hundred and twenty five consecutive patients of CD (Males: 66) were diagnosed on the basis of a combination of standard clinical, endoscopic, imaging and histological features. CD activity index (CDAI) was used to calculate the activity of the disease while the behavior of the disease was assessed by the modified Montreal classification. IP was measured by the ratio of the percentage excretion of ingested doses of lactulose and mannitol in urine (LMR). The upper limit of normality of LMR (0.037) was derived from 22 healthy controls. RESULTS: Thirty six percent of patients with CD had increased IP. There was no significant difference in mannitol excretion (patients vs controls = 12.5% vs 14.2%, P = 0.4652), but lactulose excretion was significantly higher in patients compared to healthy controls (patients vs controls = 0.326% vs 0.293%, P = 0.0391). The mean LMR was also significantly higher in the patients as compared to healthy controls [0.027 (0.0029-0.278) vs 0.0164 (0.0018-0.0548), P = 0.0044]. Male patients had a higher LMR compared to females [0.036 (95% CI 0.029, 0.046) vs 0.022 (95% CI 0.0178, 0.028) (P = 0.0024), though there was no difference in the number of patients with abnormal IP in boththe sexes. Patients with an ileo-colonic disease had a higher LMR than those with only colonic disease [0.045 (95% CI 0.033, 0.06) vs 0.021 (95% CI 0.017, 0.025) (P < 0.001)]. Of patients with ileo-colonic disease, 57.8% had an abnormal IP, compared to 26.7% with colonic and 15.6% with small intestinal disease. Patients with a stricturing disease had significantly higher LMR compared to non-fistulising non-stricturing disease [0.043 (95% CI 0.032, 0.058) vs 0.024 (95% CI 0.019, 0.029) (P = 0.0062)]. There was no correlation of IP with age, disease activity, duration of illness, D-xylose absorption, upper GI involvement, perianal disease, and extra- intestinal manifestations. On multiple regression analysis, male gender and ileo-colonic disease were independent factors associated with increased IP. Gender, location, behavior of the disease and upper GI involvement could explain up to 23% of variability in IP (R2 = 0.23). CONCLUSION: IP was increased in 36% of patients with CD. Male gender and an ileo-colonic disease were the independent factors associated with increased IP.展开更多

All the patients underwent MRI and endoscopy within the first year after surgery or after the restoration of intestinal continuity [median = 6 mo(5.0-9.3)]. The stools were collected the day before the colonoscopy to evaluate faecal calprotectin level. Endoscopic postoperative recurrence(POR) was defined as Rutgeerts' index ≥ i2b. The MRI was analyzed independently by two radiologists blinded from clinical data.RESULTS Apparent diffusion coefficient(ADC) was lower in patients with endoscopic POR compared to those with no recurrence(2.03 ± 0.32 vs 2.27 ± 0.38 × 10^(-3) mm^2/s, P = 0.032). Clermont score(10.4 ± 5.8 vs 7.4 ± 4.5, P = 0.038) and relative contrast enhancement(RCE)(129.4% ± 62.8% vs 76.4% ± 32.6%, P = 0.007) were significantly associated with endoscopic POR contrary to the magnetic resonance index of activity(Ma RIA)(7.3 ± 4.5 vs 4.8 ± 3.7; P = 0.15) and MR scoring system(P = 0.056). ADC < 2.35 × 10^(-3) mm^2/s [sensitivity = 0.85, specificity = 0.65, positive predictive value(PPV) = 0.85, negative predictive value(NPV) = 0.65] and RCE > 100%(sensitivity = 0.75, specificity = 0.81, PPV = 0.75, NPV = 0.81) were the best cutoff values to identify endoscopic POR. Clermont score > 6.4(sensitivity = 0.61, specificity = 0.82, PPV = 0.73, NPV = 0.74), Ma RIA > 3.76(sensitivity = 0.61, specificity = 0.82, PPV = 0.73, NPV = 0.74) and a MR scoring system ≥ MR1(sensitivity = 0.54, specificity = 0.82, PPV = 0.70, and NPV = 0.70) demonstrated interesting performances to detect endoscopic POR. Faecal calprotectin values were significantly higher in patients with endoscopic POR(114 ± 54.5 μg/g vs 354.8 ± 432.5 μg/g; P = 0.0075). Faecal calprotectin > 100 μg/g demonstrated high performances to detect endoscopic POR(sensitivity = 0.67, specificity = 0.93, PPV = 0.89 and NPV = 0.77).CONCLUSION Faecal calprotectin and MRI are two reliable tools to detect endoscopic POR in patients with CD.展开更多

CD patients were genotyped for the three most common NOD2 variants(R702W, G908 R and L1007Pfs*2) and basal production of TNF-α was correlated to NOD2 genotype. Also, production of TNF-α was correlated to plasmatic levels of LPS Binding Protein(LBP), soluble(s) CD14 and to the activity state of the disease.RESULTS The patients with CD were characterized by a significantly higher monocyte basal expression of TNF-αcompared with healthy subjects and UC patients, and after stimulation with Pam3CSK4(ligand of TLR2/1) and MDP-L18(ligand of NOD2) this difference was maintained, while other microbial stimuli(LPS, ligand of TLR4 and Poly I:C, ligand of TLR3) induced massive activation in CD monocytes as well as in UC and in healthy control cells. There was no significant difference in the production of TNF- α between patients who carried CD-associated heterozygous or homozygous variants in NOD2 and patients with wild type NOD2 genotype. Although serum LBP levels have been shown to correlate positively with the state of activity of the disease, TNF-α production did not show a clear correlation with either LBP or s CD14 levels in plasma. Moreover, no clear correlation was seen between TNF-α production and activity indices in either CD or UC.CONCLUSION Peripheral monocytes from CD express higher basal and stimulated TNF-α than controls, regardless of NOD2 genotype and without a clear correlation with disease activity.展开更多

It is a common feature of scleroderma, and also occurs in dermatomyositis and polymyositis, mixed connective tissue disease, Sjogren's syndrome, rheumatoid arthritis, systemic lupus erythematosus, and Antineutrophil cytoplasmic antibody-associated vasculitis. When present, it is associated with increased morbidity and mortality, thus making early diagnosis important. In fact, in many patients, ILD may be the first manifestation of a collagen vascular disease. The most common symptoms are cough and dyspnea. The diagnosis is made based on pulmonary function tests showing restrictive lung disease and impaired oxygen diffusion and chest imaging showing ground glass infiltrates, interstitial thickening, and/or fibrosis. The most common histologic finding on lung biopsy is non-specific interstitial pneumonia, though organizing pneumonia and usual interstitial pneumonia may also be seen. Treatment is focused on addressing the underlying collagen vascular disease with immunosuppression, either with corticosteroids or a steroid-sparing agent such as cyclophosphamide, azathioprine, or mycophenolate, although the optimal agent and duration of therapy is not known. There are few clinical trials to guide therapy that focus specifically on the progression of ILD. The exception is in the case of scleroderma-associated ILD, where cyclophosphamide has been shown to be effective.展开更多

Systemic biological agents that target specific immune molecules or cells such as tumor necrosis factor(TNF)-α, interferone-α, interleukin(IL)-1, IL-6, or B cells have been used in an attempt to treat Sjogren's syndrome. However, the efficacy of systemic biological agents, other than B-cell targeting agents, has not yet been confirmed in Sjogren's syndrome. Several studies have recently evaluated the efficacy of topical administration of biological agents targeting cytokines in the treatment of dry eye disease. Topical blockade of IL-1 by using IL-1 receptor antagonist could ameliorate clinical signs and inflammation of experimental dry eye. Using a mouse model of desiccating stress-induced dry eye, we have demonstrated that topical application of a TNF-α blocking agent, infliximab, could improve tear production and ocular surface irregularity, decrease inflammatory cytokines and Th-1 CD4+ cells on the ocular surface, and increase gobletcell density in the conjunctiva. Although controversy still remains, the use of topical biological agents targeting inflammatory cytokines may be a promising therapy for human dry eye disease.展开更多

Methods: Seventy pSS patients were randomly assigned to two groups using a randomized digital table: the integrative therapy group (36 cases) and the control group (34 cases). Thirty healthy subjects were taken as a normal group. The control group was treated with hydroxychloroquine sulfate tablets alone, and the integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets. The treatment course was 6 months for both groups. Before and after treatment, serum estradiol (E2), testosterone (T), luteinizing hormone (LH), prolactin (PRL) by radioimmunoassay and immunoglobulin (IgG) by immunodiffusion, erythrocyte sedimentation rate (ESR) by Westergren, interferon-γ (IFN-γ) and interleukin-4 (IL-4) by enzyme linked immunosorbent assay were determined. Results: E2 and T levels in all patients were lower than those of normal subjects before treatment (P〈0.05) and were increased significantly after 6-month treatment (P〈0.05). ESR, FSH, LH, IgG, IFN - γ, IL - 4 and ratios of E2/T, and IFN --γ/IL in the patients were higher than those of normal subjects before the treatments (P〈0.05), and were reduced significantly after the treatments (P〈0.05). The T and IFN -γ levels and E2/T ratio in the patients treated with integrative therapy were reduced significantly compared with the control group (P〈0.05). However, the PRL levels before and after treatment were not significantly changed in the two groups (P〉0.05). The ratios of E2/T and IFN -γ/IL-4, and levels of IgG and ESR were positively correlated before and after treatment (P〈0.05). Conclusions: The ratios of E2/T and IFN - γ/ IL-4 might be used as indicators of pSS activity. Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with Western medicine could improve the therapeutic effect by regulating the reproductive endocrine-immune network in pSS patients.展开更多

Methods: A total of 66 pSS patients were randomized with tossing coins method into two groups: the integrative therapy group (34 cases) and the control group (32 cases); and 28 healthy subjects were taken as the normal group. The integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets and the control group was treated with hydroxychloroquine sulfate tablets. The treatment course was 3 months for both groups. The levels of serum immunoglobulin G (IgG), erythrocyte sedimentation rate (ESR), IFN-γand IL-4 in peripheral blood were measured before and after treatment. Results: Compared with the normal group, the levels of IgG, ESR, IFN- γ and IL-4 were significantly increased in pSS patients (P〈0.05). Remarkably, after 3 months of treatment, these levels were dramatically decreased in both the integrative therapy group and the control group, although still higher than the normal group. The levels of IgG, ESR, IFN- and IL-4 in the integrative therapy group were lower than the control group and the same group before treatment (P〈0.05). The ratio of IFN-γ/IL-4 also significantly decreased after treatment. Moreover, the level of IFN- γ, and the ratio of IFN- γ/IL-4 in the integrative theraphy group were significantly lower than the control group (P〈0.05). For all patients the ratio of IFN-γ/IL-4 before and after treatment was positive correlated with the levels of IgG and ESR.

文摘BACKGROUND Perianal fistulas pose dual challenges to Crohn's disease(CD)patients.Low patient compliance due to the complexity of existing examination methods plagues the treatment and follow-up management of perianal CD.AIM To determine the accuracy of endoanal ultrasound(EUS)and shear wave elastography(SWE)for evaluating perianal fistulizing CD(PFCD)activity.METHODS This was a retrospective cohort study.A total of 67 patients from August 2022 to December 2023 diagnosed with CD were divided into three groups:Non-anal fistula group(n=23),low-activity perianal fistulas[n=19,perianal disease activity index(PDAI)≤4],high-activity perianal fistulas(n=25,PDAI>4)based on the PDAI.All patients underwent assessments including EUS+SWE,pelvic magnetic resonance[pelvic magnetic resonance imaging(MRI)],C-reactive protein,fecal calprotectin,CD activity index,PDAI.RESULTS The percentage of fistulas indicated by pelvic MRI and EUS was consistent at 82%,and there was good consistency in the classification of perianal fistulas(Kappa=0.752,P<0.001).Significant differences were observed in the blood flow Limberg score(χ^(2)=8.903,P<0.05)and shear wave velocity(t=2.467,P<0.05)between group 2 and 3.Shear wave velocity showed a strong negative correlation with magnetic resonance novel index for fistula imaging in CD(Magnifi-CD)score(r=-0.676,P<0.001),a weak negative correlation with the PDAI score(r=-0.386,P<0.05),and a weak correlation between the Limberg score and the PDAI score(r=0.368,P<0.05).CONCLUSION EUS combined with SWE offers a superior method for detecting and quantitating the activity of perianal fistulas in CD patients.It may be the ideal tool to assess PFCD activity objectively for management strategies.
文摘This case study aims to contribute to the literature in order to highlight the importance of this collaboration between medical specialties. A female patient R.N.N. F, age 66, from the city of Manaus, with a previous diagnosis of Sjogren’s syndrome in regular follow-up by the Rheumatology team at the Araujo Lima outpatient clinic and referred to the Ophthalmology sector for complementary evaluation related to visual discomfort. The fundoscopy performed in the patient was within normal limits, but the symptoms experienced by her proved to be an important clinical finding, which has ratified the need for regular and multidisciplinary follow-up. This report unequivocally demonstrates that even in the face of tests considered within the expected limits for a given population, the clinical presentation can be specific and particular for each analyzed individual. Early screening exams should contemplate the patient in a holistic and individualized way whenever possible.
文摘Rheumatoid Arthritis (RA) is an inflammatory disease associated with high morbidity and increased cardiovascular disease, and Metabolic Syndrome (MS) is understood as a set of metabolic disorders that correlates with obesity and sedentary lifestyle. The aim of this study is to evaluate the prevalence of MS in a cohort of patients with RA and its correlation to specific factors of the disease. A retrospective cohort study was conducted with 283 patients with RA, followed at the Rheumatology Outpatient Clinic of the Hospital de Clínicas de Porto Alegre (HCPA) between 2008 and 2016;187 continued to be followed and agreed to be reevaluated between January and November 2016. MS was defined according to the National Cholesterol Education Program and disease activity was assessed using the Disease Activity Score (DAS28). Clinical, biochemical, and anthropometric evaluations were conducted. The prevalence of MS in the first evaluation was 43.9% and, after 8 years, 59.4%. Increased waist circumference and blood pressures, elevated triglycerides and low High-Density Lipoprotein were the most frequent features of MS. The DAS28 was significantly lower in the reevaluation (p = 0.006). The prevalence of MS was higher at the end of 8 years;disease activity, as well as blood pressure, decreased during this period. Steroid use had also decreased at the end of follow-up. There was an increase of 15% of cases with MS in an 8-year follow-up cohort of patients, which was in agreement with the current literature and showed how the inflammatory process in RA is correlated to MS. The parameters of MS that varied the most were blood pressure, cholesterol and triglycerides. Ultimately, these parameters and disease activity must be observed closely in order to improve the prognosis of patients with RA.
文摘The Crohn's disease activity index (CDAI) has been commonly used to assess the effects of treatment with different agents in Crohn's disease (CD). However, these studies may be compromised, if the results compared to a placebo or standard therapy group (in the absence of a placebo) substantially differ from the expected response. In addition, significant concerns have been raised regarding the reliability and validity of the CDAI. Reproducibility of the CDAI may be limited as significant inter-observer error has been recorded, even if measurements are done by experienced clinicians with expertise in the diagnosis and treatment of CD. Finally, many CDAI endpoints are open to subjective interpretation and have the potential for manipulation. This is worrisome as there is the potential for significant financial gain, if the results of a clinical trial appear to provide a positive result. Physicians caring for patients should be concerned about the positive results in clinical trials that are sponsored by industry, even if the trials involve respected centers and the results appear in highly ranked medical journals.
文摘BACKGROUND The pediatric Crohn’s disease activity index(PCDAI)is used as a standard tool to assess disease activity in clinical trials for pediatric Crohn’s disease.AIM To examine which items on the PCDAI drive assessment of disease activity,and how subgroups of subjective and objective items reflect change in disease state over time.METHODS Selective raw data from three prospectively collected datasets were combined,including 703 children with full PCDAI data at baseline,at 3-mo(Q1,n=670),and 1-year(Q4,n=474).Change in individual PCDAI scores from baseline to Q1 and to Q4 were examined using the non-weighted PCDAI.RESULTS Abdominal pain,well-being,weight,and stooling had the highest change scores over time.Objective indicators including albumin,abdominal exam,and height velocity followed.Change scores for well-being and abdominal exam did not explain significant variance at Q1 but were significant predictors at Q4(P<0.001 and P<0.05).Subjective and objective subgroups of items predicted less variance(18%and 22%)on total PCDAI scores at Q1 and Q4 compared to the full PCDAI,or a composite scale(both 32%)containing significant predictors.CONCLUSION Although subjective items on the PCDAI change the most over time,the full PCDAI or a smaller composite of items including a combination of subjective and objective components classifies disease activity better than a subgroup of either subjective or objective items alone.Reliance on subjective or objective items as stand-alone proxies for disease activity measurement could result in misclassification of disease state.
文摘Sjogren’s syndrome is a chronic autoimmune exocrinopathy associated with dry eyes and dry mouth as major clinical manifestations. It is characterized by lymphocytic infiltration of lacrimal and salivary glands and autoantibody production, especially anti-Ro (or SSA) and anti-La (or SSB). Lymphoproliferative disorders are a feature of Sjogren’s syndrome, and can be considered an extraglandular manifestation of the disease. Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a rare form of lymphadenitis. It is reported more often in young adult women with localized lymphadenopathy (usually cervical), fever, rashes, and leukopenia. It is a self-limiting disease with resolution within 1 - 4 months in almost all patients. Sjogren’s syndrome has been reported in patients with other systemic diseases including SLE and lymphomas. Here we present a patient with Kikuchi-Fujimoto disease who developed Sjogren’s Syndrome 8 years after her diagnosis of Kikuchi-Fujimoto disease.
文摘Background: Rheumatoid arthritis (RA) is a chronic and disabling disease that has a major impact on the lives of patients. Objectives: To test the patients’ knowledge about their disease, its treatment, its complications, and if this affects severity of the disease as measured by the disease activity index (DAS 28). Patients and Methods: A sample of 100 patients with RA who met the Criteria of American College of Rheumatology for RA agreed to participate in this study over the period September 2011-March 2012. Patients’ data were obtained by personal interview. The questionnaire included demographic characteristics and the patients’ knowledge about their disease. The disease activity was measured using standard (DAS28). Results: Thirty three percent of the patients didn’t have an idea about their disease, 20% didn’t know the reason for the investigations, 49% didn’t know the treatment and 40% didn’t know the side effects of their medications. Most patients had a high disease activity index, and there was a poor correlation between patients’ educational level and the disease activity. Conclusions: Neither the educational level nor the frequency of hospital admissions had effects on the knowledge about this disease. As most patients had a high disease activity, a better knowledge may improve disease control and prevent complications.
文摘Mesenteric Panniculitis is a benign fibro-inflammatory process involving adipose tissue of the mesentery. It is characterised by fat necrosis, chronic inflammation and fibrosis, causing thickening and shortening of the mesentery. Patients may present with localised abdominal pain, abdominal mass, intestinal obstruction and ischaemic colitis. We report a case of mesenteric panniculitis causing abdominal pain in a patient with active Primary Sjogren’s Syndrome. The rarity of this case makes it of interest. We review the current literature on mesenteric panniculitis and its association with connective tissue disease and inflammatory conditions. A 64-year-old Caucasian male presented in 1994 with dry mouth. A diagnosis of Primary Sjogren’s Syndrome (PSS) was made on salivary gland biopsy. In 2010 he presented with an exacerbation of his eye symptoms, muscle pain and fatigue. He complained of abdominal pain and night sweating, but denied any weight loss or change in bowel habit. There was no significant past medical history other than PSS. On examination he had a small right submandibular node and mild synovitis at the right proximal interphalangeal joint and carpometacarpal joint. Examination of the abdomen showed marked umbilical tenderness but no organomegally. Blood tests at this time showed an active inflammation: CRP of 61 (NR 5 mg/L), ESR 39 (NR 20 mm/s), strongly positive ENA Ro and La. IgG was elevated at 18.6 (NR 5.8-15.4), Complement was low at 0.17 (NR 0.18-0.6). An abdominal ultrasound scan demonstrated a 6 × 3 ×3 cmarea of diffuse homogenous fat encasing some mesenteric vessels in the area of focal tenderness. CT abdomen and pelvis showed oedematous mesenteric fat and lymph nodes in the jejunal small bowel mesentery, consistent with mesenteric panniculitis. Laparoscopic biopsy was discussed with the surgical team, but was felt not indicated as risk outweighed potential benefit. The patient was treated with a 9-week reducing course of oral steroids. His abdominal symptoms resolved although CT abdomen showed little improvement in mesenteric panniculitis. A review of the literature suggests that currently there is no standard treatment and management should be guided by patient symptoms. Mesenteric Panniculitis is rare;as a result evidence for treatment is limited to individual case reports. There is no clear link between symptom improvement and radiological resolution of mesenteric panniculitis. It has, therefore been suggested that follow-up imaging should be limited to those with persistent symptoms. Overall the prognosis for mesenteric panniculitis is good, up to half of patients do not require treatment, and recurrence of symptoms is uncommon.

文摘AIM:To establish the frequency and clinical features of connective tissue diseases(CTDs)in a cohort of Chinese patients with primary biliary cirrhosis(PBC).METHODS:Three-hundred and twenty-two Chinese PBC patients were screened for the presence of CTD,and the systemic involvement was assessed.The differences in clinical features and laboratory findings between PBC patients with and without CTD were documented.The diversity of incidence of CTDs in PBC of different countries and areas was discussed.For the comparison of normally distributed data,Student’s t test was used,while non-parametric test(Wilcoxon test)for the non-normally distributed data and 2×2χ2or Fisher’s exact tests for the ratio.RESULTS:One-hundred and fifty(46.6%)PBC patients had one or more CTDs.The most common CTD was Sj gren’s syndrome(SS,121 cases,36.2%).There were nine cases of systemic sclerosis(SSc,2.8%),12of systemic lupus erythematosus(SLE,3.7%),nine of rheumatoid arthritis(RA,2.8%),and 10 of polymyositis(PM,3.1%)in this cohort.Compared to patients with PBC only,the PBC+SS patients were more likely to have fever and elevated erythrocyte sedimentation rate(ESR),higher serum immunoglobulin G(IgG)levels and more frequent rheumatoid factor(RF)and interstitial lung disease(ILD)incidences;PBC+SSc patients had higher frequency of ILD;PBC+SLE patients had lower white blood cell(WBC)count,hemoglobin(Hb),platelet count,γ-glutamyl transpeptidase and immunoglobulin M levels,but higher frequency of renal involvement;PBC+RA patients had lower Hb,higher serum IgG,alkaline phosphatase,faster ESR and a higher ratio of RF positivity;PBC+PM patients had higher WBC count and a tendency towards myocardial involvement.CONCLUSION:Besides the common liver manifestation of PBC,systemic involvement and overlaps with other CTDs are not infrequent in Chinese patients.When overlapping with other CTDs,PBC patients manifested some special clinical and laboratory features which may have effect on the prognosis.
文摘AIM:To assess the intestinal permeability (IP) in patients with Crohn's disease (CD) and study the association of IP with the patient and disease characteristics. METHODS: One hundred and twenty five consecutive patients of CD (Males: 66) were diagnosed on the basis of a combination of standard clinical, endoscopic, imaging and histological features. CD activity index (CDAI) was used to calculate the activity of the disease while the behavior of the disease was assessed by the modified Montreal classification. IP was measured by the ratio of the percentage excretion of ingested doses of lactulose and mannitol in urine (LMR). The upper limit of normality of LMR (0.037) was derived from 22 healthy controls. RESULTS: Thirty six percent of patients with CD had increased IP. There was no significant difference in mannitol excretion (patients vs controls = 12.5% vs 14.2%, P = 0.4652), but lactulose excretion was significantly higher in patients compared to healthy controls (patients vs controls = 0.326% vs 0.293%, P = 0.0391). The mean LMR was also significantly higher in the patients as compared to healthy controls [0.027 (0.0029-0.278) vs 0.0164 (0.0018-0.0548), P = 0.0044]. Male patients had a higher LMR compared to females [0.036 (95% CI 0.029, 0.046) vs 0.022 (95% CI 0.0178, 0.028) (P = 0.0024), though there was no difference in the number of patients with abnormal IP in boththe sexes. Patients with an ileo-colonic disease had a higher LMR than those with only colonic disease [0.045 (95% CI 0.033, 0.06) vs 0.021 (95% CI 0.017, 0.025) (P < 0.001)]. Of patients with ileo-colonic disease, 57.8% had an abnormal IP, compared to 26.7% with colonic and 15.6% with small intestinal disease. Patients with a stricturing disease had significantly higher LMR compared to non-fistulising non-stricturing disease [0.043 (95% CI 0.032, 0.058) vs 0.024 (95% CI 0.019, 0.029) (P = 0.0062)]. There was no correlation of IP with age, disease activity, duration of illness, D-xylose absorption, upper GI involvement, perianal disease, and extra- intestinal manifestations. On multiple regression analysis, male gender and ileo-colonic disease were independent factors associated with increased IP. Gender, location, behavior of the disease and upper GI involvement could explain up to 23% of variability in IP (R2 = 0.23). CONCLUSION: IP was increased in 36% of patients with CD. Male gender and an ileo-colonic disease were the independent factors associated with increased IP.
文摘AIM To assess magnetic resonance imaging(MRI) and faecal calprotectin to detect endoscopic postoperative recurrence in patients with Crohn's disease(CD).METHODS From two tertiary centers, all patients with CD who underwent ileocolonic resection were consecutively and prospectively included. All the patients underwent MRI and endoscopy within the first year after surgery or after the restoration of intestinal continuity [median = 6 mo(5.0-9.3)]. The stools were collected the day before the colonoscopy to evaluate faecal calprotectin level. Endoscopic postoperative recurrence(POR) was defined as Rutgeerts' index ≥ i2b. The MRI was analyzed independently by two radiologists blinded from clinical data.RESULTS Apparent diffusion coefficient(ADC) was lower in patients with endoscopic POR compared to those with no recurrence(2.03 ± 0.32 vs 2.27 ± 0.38 × 10^(-3) mm^2/s, P = 0.032). Clermont score(10.4 ± 5.8 vs 7.4 ± 4.5, P = 0.038) and relative contrast enhancement(RCE)(129.4% ± 62.8% vs 76.4% ± 32.6%, P = 0.007) were significantly associated with endoscopic POR contrary to the magnetic resonance index of activity(Ma RIA)(7.3 ± 4.5 vs 4.8 ± 3.7; P = 0.15) and MR scoring system(P = 0.056). ADC < 2.35 × 10^(-3) mm^2/s [sensitivity = 0.85, specificity = 0.65, positive predictive value(PPV) = 0.85, negative predictive value(NPV) = 0.65] and RCE > 100%(sensitivity = 0.75, specificity = 0.81, PPV = 0.75, NPV = 0.81) were the best cutoff values to identify endoscopic POR. Clermont score > 6.4(sensitivity = 0.61, specificity = 0.82, PPV = 0.73, NPV = 0.74), Ma RIA > 3.76(sensitivity = 0.61, specificity = 0.82, PPV = 0.73, NPV = 0.74) and a MR scoring system ≥ MR1(sensitivity = 0.54, specificity = 0.82, PPV = 0.70, and NPV = 0.70) demonstrated interesting performances to detect endoscopic POR. Faecal calprotectin values were significantly higher in patients with endoscopic POR(114 ± 54.5 μg/g vs 354.8 ± 432.5 μg/g; P = 0.0075). Faecal calprotectin > 100 μg/g demonstrated high performances to detect endoscopic POR(sensitivity = 0.67, specificity = 0.93, PPV = 0.89 and NPV = 0.77).CONCLUSION Faecal calprotectin and MRI are two reliable tools to detect endoscopic POR in patients with CD.

文摘AIM To evaluate the inflammatory state in Crohn's disease(CD) patients and correlate it with genetic background and microbial spreading.METHODS By means of flow cytometry, production of tumor necrosis factor-alpha(TNF-α) was measured in peripheral blood monocytes from patients suffering from CD, ulcerative colitis(UC) and in healthy subjects after stimulation of the NOD2 and TLR pathways. CD patients were genotyped for the three most common NOD2 variants(R702W, G908 R and L1007Pfs*2) and basal production of TNF-α was correlated to NOD2 genotype. Also, production of TNF-α was correlated to plasmatic levels of LPS Binding Protein(LBP), soluble(s) CD14 and to the activity state of the disease.RESULTS The patients with CD were characterized by a significantly higher monocyte basal expression of TNF-αcompared with healthy subjects and UC patients, and after stimulation with Pam3CSK4(ligand of TLR2/1) and MDP-L18(ligand of NOD2) this difference was maintained, while other microbial stimuli(LPS, ligand of TLR4 and Poly I:C, ligand of TLR3) induced massive activation in CD monocytes as well as in UC and in healthy control cells. There was no significant difference in the production of TNF- α between patients who carried CD-associated heterozygous or homozygous variants in NOD2 and patients with wild type NOD2 genotype. Although serum LBP levels have been shown to correlate positively with the state of activity of the disease, TNF-α production did not show a clear correlation with either LBP or s CD14 levels in plasma. Moreover, no clear correlation was seen between TNF-α production and activity indices in either CD or UC.CONCLUSION Peripheral monocytes from CD express higher basal and stimulated TNF-α than controls, regardless of NOD2 genotype and without a clear correlation with disease activity.
文摘Interstitial lung disease(ILD) is an important mani-festation of collagen vascular diseases. It is a common feature of scleroderma, and also occurs in dermatomyositis and polymyositis, mixed connective tissue disease, Sjogren's syndrome, rheumatoid arthritis, systemic lupus erythematosus, and Antineutrophil cytoplasmic antibody-associated vasculitis. When present, it is associated with increased morbidity and mortality, thus making early diagnosis important. In fact, in many patients, ILD may be the first manifestation of a collagen vascular disease. The most common symptoms are cough and dyspnea. The diagnosis is made based on pulmonary function tests showing restrictive lung disease and impaired oxygen diffusion and chest imaging showing ground glass infiltrates, interstitial thickening, and/or fibrosis. The most common histologic finding on lung biopsy is non-specific interstitial pneumonia, though organizing pneumonia and usual interstitial pneumonia may also be seen. Treatment is focused on addressing the underlying collagen vascular disease with immunosuppression, either with corticosteroids or a steroid-sparing agent such as cyclophosphamide, azathioprine, or mycophenolate, although the optimal agent and duration of therapy is not known. There are few clinical trials to guide therapy that focus specifically on the progression of ILD. The exception is in the case of scleroderma-associated ILD, where cyclophosphamide has been shown to be effective.

文摘Because inflammation plays a key role in the pathogenesis of dry eye disease and Sjogren's syndrome, topical anti-inflammatory agents such as corticosteroids and cyclosporine A have been used to treat inflammation of the ocular surface and lacrimal gland. Systemic biological agents that target specific immune molecules or cells such as tumor necrosis factor(TNF)-α, interferone-α, interleukin(IL)-1, IL-6, or B cells have been used in an attempt to treat Sjogren's syndrome. However, the efficacy of systemic biological agents, other than B-cell targeting agents, has not yet been confirmed in Sjogren's syndrome. Several studies have recently evaluated the efficacy of topical administration of biological agents targeting cytokines in the treatment of dry eye disease. Topical blockade of IL-1 by using IL-1 receptor antagonist could ameliorate clinical signs and inflammation of experimental dry eye. Using a mouse model of desiccating stress-induced dry eye, we have demonstrated that topical application of a TNF-α blocking agent, infliximab, could improve tear production and ocular surface irregularity, decrease inflammatory cytokines and Th-1 CD4+ cells on the ocular surface, and increase gobletcell density in the conjunctiva. Although controversy still remains, the use of topical biological agents targeting inflammatory cytokines may be a promising therapy for human dry eye disease.
文摘Capsule endoscopy(CE)is a recently developed diagnostic method for diseases of the small bowel that is non-invasive,safe,and highly tolerable.Its role in patients with inflammatory bowel disease has been widely validated in suspected and established Crohn’s disease(CD)due to its ability to assess superficial lesions not detected by cross-sectional imaging and proximal lesions of the small bowel not evaluable by ileocolonoscopy.Because CE is a highly sensitive but less specific technique,differential diagnoses that can simulate CD must be considered,and its interpretation should be supported by other clinical and laboratory indicators.The use of validated scoring systems to characterize and estimate lesion severity(Lewis score,Capsule Endoscopy Crohn’s Disease Activity Index),as well as the standardization of the language used to define the lesions(Delphi Consensus),have reduced the interobserver variability in CE reading observed in clinical practice,allowing for the optimization of diagnoses and clinical management strategies.The appearance of the panenteric CE,the incorporation of artificial intelligence,magnetically-guided capsules,and tissue biopsies are elements that contribute to CE being a promising,unique diagnostic tool in digestive tract diseases.

文摘ABSTRACT Objective: To investigate the effect of Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood on the reproductive endocrine-immune network and its mechanisms in patients with primary Sjogren's syndrome (pSS). Methods: Seventy pSS patients were randomly assigned to two groups using a randomized digital table: the integrative therapy group (36 cases) and the control group (34 cases). Thirty healthy subjects were taken as a normal group. The control group was treated with hydroxychloroquine sulfate tablets alone, and the integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets. The treatment course was 6 months for both groups. Before and after treatment, serum estradiol (E2), testosterone (T), luteinizing hormone (LH), prolactin (PRL) by radioimmunoassay and immunoglobulin (IgG) by immunodiffusion, erythrocyte sedimentation rate (ESR) by Westergren, interferon-γ (IFN-γ) and interleukin-4 (IL-4) by enzyme linked immunosorbent assay were determined. Results: E2 and T levels in all patients were lower than those of normal subjects before treatment (P〈0.05) and were increased significantly after 6-month treatment (P〈0.05). ESR, FSH, LH, IgG, IFN - γ, IL - 4 and ratios of E2/T, and IFN --γ/IL in the patients were higher than those of normal subjects before the treatments (P〈0.05), and were reduced significantly after the treatments (P〈0.05). The T and IFN -γ levels and E2/T ratio in the patients treated with integrative therapy were reduced significantly compared with the control group (P〈0.05). However, the PRL levels before and after treatment were not significantly changed in the two groups (P〉0.05). The ratios of E2/T and IFN -γ/IL-4, and levels of IgG and ESR were positively correlated before and after treatment (P〈0.05). Conclusions: The ratios of E2/T and IFN - γ/ IL-4 might be used as indicators of pSS activity. Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with Western medicine could improve the therapeutic effect by regulating the reproductive endocrine-immune network in pSS patients.
文摘Objective: To observe the effect of Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood on the expression of interferen- γ (IFN-γ,)/interleukin-4 (IL-4) in peripheral blood and disease activity in primary Sjogren's syndrome (pSS) patients, and to study the relationship between the immune balance of Th1/Th2 and the disease activity. Methods: A total of 66 pSS patients were randomized with tossing coins method into two groups: the integrative therapy group (34 cases) and the control group (32 cases); and 28 healthy subjects were taken as the normal group. The integrative therapy group was treated by Chinese herbal medicines for nourishing yin, supplementing qi, and activating blood combined with hydroxychloroquine sulfate tablets and the control group was treated with hydroxychloroquine sulfate tablets. The treatment course was 3 months for both groups. The levels of serum immunoglobulin G (IgG), erythrocyte sedimentation rate (ESR), IFN-γand IL-4 in peripheral blood were measured before and after treatment. Results: Compared with the normal group, the levels of IgG, ESR, IFN- γ and IL-4 were significantly increased in pSS patients (P〈0.05). Remarkably, after 3 months of treatment, these levels were dramatically decreased in both the integrative therapy group and the control group, although still higher than the normal group. The levels of IgG, ESR, IFN- and IL-4 in the integrative therapy group were lower than the control group and the same group before treatment (P〈0.05). The ratio of IFN-γ/IL-4 also significantly decreased after treatment. Moreover, the level of IFN- γ, and the ratio of IFN- γ/IL-4 in the integrative theraphy group were significantly lower than the control group (P〈0.05). For all patients the ratio of IFN-γ/IL-4 before and after treatment was positive correlated with the levels of IgG and ESR. Conclusion: Chinese herbal medicine for nourishing yin, supplementing qi, and activating blood can alleviate the disease activity of pSS by regulating the immune balance of Th1/Th2.
