Rhabdomyolysis or myositis was suggested by magnetic resonance imaging and repeated four times within 4 years. Each episode developed following respiratory infection and spontaneously recovered. The diagnosis of Sjogren’s syndrome was made by decreased salivary secretion, MR sialography, lip biopsy, and positive anti-SSA/Ro antibody. Given the rarity of rhabdomyolysis/myositis, recurrent episode could be induced by infectious disease on the basis of underlying Sjogren’s syndrome. Conclusion: Sjogren’s syndrome should be considered as an underlying disease of recurrent infection-induced rhabdomyolysis/ myositis.展开更多

Mothoda Patients who were diagnosed by the experts/rheumatologists as pSS during 1990-2002 from the Department of Rheumatology, Peking Union Medical College Hospital were retrospectively collected as experimental group. Patients who were diagnosed as non-pSS connective tissue diseases or non-connective tissue diseases served as control group. Those with a history of head-neck radiation, hepatitis C virus infection, AIDS, lymphoma, sarcoidosis, graft versus host disease (GVHD), and anti-acetylcholine drug use were exempted. Both groups were required to complete questionnaires about symptoms such as dry eyes and dry mouth, and complete the objective tests of keratoconjunctivitis and xerostomia including Schirmer test, corneal staining, unstimulated salivary flow, sialography, lower lip biopsy, and antinuclear antibodies (including anti-SSA/SSB antibodies) test. Results A total of 330 pSS patients were included in experimental group and 185 non-pSS patients in control group. The mean age of both groups matched (47.8 ± 10.9 years vs. 46.2±13.6 years, P 〉 0.05). The sensitivities of the criteria in pSS patients with lower lip biopsy and in pSS patients without lower lip biopsy were 89.2% and 87.2%, respectively; the overall sensitivity was 88.5%. The specificity was 97.3%. A total of 11.3% pSS patients with negative anti-SSA/SSB antibodies were diagnosed as pSS by lower lip biopsy. Coadwion The international classification criteria (2002) for pSS is feasible in Chinese patients. It has high sensitivity and specificity, and may serve as diagnosis criteria in routine clinical practice.展开更多

The differences of the above parameters between the two groups were examined, and the relationship between corneal biomechanics and tear film parameters were observed. RESULTS:The differences in age, sex, intraocular pressure(IOP) and central corneal thickness(CCT) were not significant between the two groups(P〉0.05). The tear film parameters had significant differences between the SSDE group and NSSDE group(all P〈0.05). Patients in the SSDE group had significantly lower A1-time and HC-time, but higher DA(P=0.01, 0.02, and 0.02, respectively) compared with the NSSDE group. In the SSDE group, DA was negatively correlated with TBUT(rho=-0.38, P=0.03); HC-time was negatively correlated with CSS(rho=-0.43, P=0.02). In the NSSDE group, HC-time was again negatively correlated with CSS(rho=-0.39, P=0.02).CONCLUSION:There are differences in corneal biomechanical properties between SSDE and NSSDE. The cornea of SSDE tends to show less "stiffness", as seen by a significantly shorter A1-time and HC-time, but larger DA, compared with the cornea of NSSDE. Biomechanical parameters can be influenced by different tear film parameters in both groups.展开更多

We compared the clinical features of 16 neuro- myelitis optica spectrum disorder patients with (n = 6) or without primary Sjogreffs syndrome (n = 10). All patients underwent extensive clinical, laboratory, and MRI evaluations. There were no statistical differences in demographics or first neurological involvement at onset between neuromyelitis optica spectrum disorder patients with and without primary Sjogren's syndrome. The laboratory findings of cerebrospinal fluid oligoclonal banding, serum C-reactive protein, antinudear autoantibody, anti-Sjogren's-syndrome-related antigen A an- tibodies, anti-Sjogren's-syndrome-related antigen B antibodies, and anti-Sm antibodies were significantly higher in patients with primary Sjogren's syndrome than those without. Anti-aquaporin 4 antibodies were detectable in 67% (4/6) of patients with primary Sjogren's syndrome and in 60% (6/10) of patients without primary Sj6gren's syndrome. More brain abnormalities were observed in patients without primary Sj6gren's syndrome than in those with primary Sj6gren's syndrome. Segments lesions (〉 3 centrum) were noted in 50% (5/10) of patients without primary Sj6gren's syndrome and in 67% (4/6) of patients with primary Sjogren's syndrome. These findings indicate that the clinical characteristics of neuromyelitis optica spectrum disorder patients with and without primary Sjogren's syndrome are similar. However, neu- romyelitis optica spectrum disorder patients without primary Sjogreffs syndrome have a high frequency of brain abnormalities.展开更多

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

Methods: We developed an in vitro model of Sjogren’s syndrome by transfecting human salivary gland (HSG) and acinar cells (NS-SV-AC) with a plasmid-encoding IκBαM (pCMV-IκBαM), a degradation-resistant IκBα (nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha)-mutant, and examined TNF-induced apoptosis and anti-apoptotic properties of NF-κB. Apoptosis and induction of pro-apoptotic and anti-apoptotic genes were investigated by cDNA arrays, RT-PCR, electrophoretic mobility shift assays, and western blot. Results: In the presence of NF-κB inhibitors, TNF-induced apoptosis was markedly increased in both salivary gland and acinar cells. Increased caspase-3 activity was present in both HSG and NS-SV-AC cells. IκBαM-transfected salivary gland cells were more sensitive to TNF-induced apoptosis than IκBαM-transfected acinar cells. Transcription of pro-apoptotic genes was confirmed in both HSG and NS-SV-AC cells that were transfected with IκBαM. Results from caspase-3 activity assay confirmed previous experiments showing an apoptotic role for NF-κB. Conclusion: Data from gene expression arrays suggest that different mechanisms may operate during TNF-induced apoptosis in salivary gland ductal and acinar cells.展开更多

As a systemic autoimmune disease, primary Sjogren’s syndrome(pSS) cannot be completely cured. Human studies have revealed that GM species and diversity are altered in patients with p SS compared with healthy individuals. Animal studies have provided possible mechanisms for the association between pSS and GM. The potential role of GM in pSS is exerted through several mechanisms. GM dysbiosis leads to increased intestinal permeability, which increases the risk of GM antigen exposure and activates specific autoreactive T lymphocytes via “molecular mimicry”. In addition, GM antigen exposure and intestinal immune tolerance loss caused by GM dysbiosis together induce chronic local gut mucosal inflammation, which deteriorates to systemic chronic non-specific inflammation with the circulation of pro-inflammatory lymphocytes and cytokines. These factors eventually activate autoreactive B lymphocytes and lead to pSS. If GM plays a key role in the pathogenesis of pSS, clarifying the underlying mechanisms will be helpful for the development of new therapies targeting GM for dry eye associated with pSS. This review summarizes the latest knowledge about the relationship between GM and p SS,with the aim of contributing to future research and to the development of new clinical applications.展开更多

Although ocular and oral dryness are the hallmarks of this syndrome, renal involvement when present most commonly has the histological appearance of tubointerstitial nephritis and less often glomerular involvement. We report, a unique case of renal manifestations of primary Sjogren’s syndrome with a proven histological focal proliferative and crescentric necrotizing glomeru-lonephritis. Case: A 30 years old man with Kimura disease presented with four months of subjective fevers, migrating skin erythema, dry mouth, and dry eyes. On further workup the patient was found to have a positive ANA, positive anti-SSA, and was evaluated by ophthalmology who found keratoconjunctivitis sicca. The patient was started on hydroxychloroquine in combination with prednisone. On follow up, the patient was found to be hypertensive with acute kidney injury, a creatinine of 3.65, proteinuria and hematuria. Renal ultrasound was unremarkable. Cytoplasmic ANCA was positive and kidney biopsy was performed revealing non pauci-immune focal proliferative and necrotizing glomerulonephritis with cellular crescents and mesangial dense deposits by electron microscopy. Conclusion: To our knowledge, the association between biopsy proven focal proliferative and necrotizing glomerulonephritis with primary Sjogren’s syndrome has never been previously described in the literature, nor has there been a reported case of association between Kimura disease, ANCA serology and primary Sjogren’s syndrome.展开更多

In addition to a systemic autoimmune response directed against ubiquitous antigens (such as Ro and La antigens), patients with SS mount a localized response that affects the epithelial component of exocrine glands leading to the establishment of a destructive inflammatory infiltrate comprised of activated T and B cells. Local chemokine and cytokine production drive the recruitment and local activation of immune cells that cause injury to acinar cells. CD4 T cells with different functional differentiation programs including Th1 (IFN-γ), Th2 (IL-13, IL-4) and Th17 (IL-17, IL-21, IL-22) as well as diverse cytokine signaling pathways, are involved at the initiation, perpetuation, and progression of the disease. Which factors initiate this response and allow it to become chronic are unknown. Proposed mecha-nisms include viral infections and acinar cell apoptosis. Moreover risk-conferring genetic variants, probably through the facilitation of innate and adaptive immune activation, most certainly contribute to the creation of an underlying environment that fosters tolerance loss and facilitates perpetuation of the autoimmune response. In this review, we describe the mechanisms through which the immune response causes SS and emphasize the pathways that are amenable of being targeted with therapeutic purposes.展开更多

The clinical feature is rarely revealed by manifestations due to hypokalemia. We report the case of a 46-year-old woman, admitted to explore a paresthesia and paresis of inferior limbs. The diagnosis of Sjögren’s syndrome was retained since there was the association of xerophthalmia, sialadenitis at the labial biopsy and positive immunological results (anti-SSA and anti-SSB). The absence of another auto-immune or systemic illness allowed us to consider that the Sjögren’s syndrome was primary. The biological explorations revealed a hyperchloremic and hypokalemic acidosis. The treatment was based on corticosteroid and potassium supplementation. The follow-up was marked by a clinical and biological amelioration.展开更多

However, ...Salts of calcium phosphate and inorganic phosphate are normally found in serum and extracellular fluids, balancing through poorly understood factors that prevent abnormal tissue deposition of these minerals. However, in those tissues that are injured, especially due to chronic inflammatory processes, a predisposition to the deposition of these minerals is developed, triggering what has been called Dystrophic Calcinosis (DC), common in different Connective Tissue Diseases (CTD), especially dermatomyositis and scleroderma, but there is no a frecuent association with diseases like Rheumatoid Arthritis (RA) and Sj?gren Syndrome (SS). We report a case of a female patient of 63 years old with RA and Secundary SS who presents with DC in the hands and no evidence of other connective tissue.展开更多

文摘BACKGROUND Sj?gren syndrome(SS)is a chronic and systemic autoimmune disease characterized by lymphocytic infiltration of the exocrine glands.And histoplasmosis is an invasive mycosis caused by the saprophytic dimorphic fungus H.capsulatum.In patients with primary SS(PSS),disseminated histoplasmosis(DH)is extremely rare.CASE SUMMARY We report a 37-year-old female patient admitted to our hospital with exacerbating fatigue,somnolence,and pancytopenia as the main symptoms.She was eventually diagnosed with DH based on pancytopenia,splenomegaly,and findings of bone marrow smears.The atypical clinical symptoms made the diagnosis process more tortuous.Unfortunately,she died of respiratory failure on the day the diagnosis was confirmed.CONCLUSION We present a rare and interesting case of DH in a PSS patient.This case updates the geographic distribution of histoplasmosis in China,and expands the clinical manifestations of DH in PSS,highlighting the significance of constantly improving the understanding of PSS with DH.
文摘We report a 9-year-old Japanese girl who presented with muscle weakness and elevated serum levels of muscle-derived enzymes following mycoplasma infection. Rhabdomyolysis or myositis was suggested by magnetic resonance imaging and repeated four times within 4 years. Each episode developed following respiratory infection and spontaneously recovered. The diagnosis of Sjogren’s syndrome was made by decreased salivary secretion, MR sialography, lip biopsy, and positive anti-SSA/Ro antibody. Given the rarity of rhabdomyolysis/myositis, recurrent episode could be induced by infectious disease on the basis of underlying Sjogren’s syndrome. Conclusion: Sjogren’s syndrome should be considered as an underlying disease of recurrent infection-induced rhabdomyolysis/ myositis.

文摘AIM:To compare the corneal biomechanics of Sj?gren's syndrome(SS) and non-SS dry eyes with Corneal Visualization Scheimpflug Technology(CorV is ST).METHODS:Corneal biomechanics and tear film parameters, namely the Schirmer I test value, tear film break-up time(TBUT) and corneal staining score(CSS) were detected in 34 eyes of 34 dry eye patients with SS(SSDE group) and 34 dry eye subjects without SS(NSSDE group) using CorV is ST. The differences of the above parameters between the two groups were examined, and the relationship between corneal biomechanics and tear film parameters were observed. RESULTS:The differences in age, sex, intraocular pressure(IOP) and central corneal thickness(CCT) were not significant between the two groups(P〉0.05). The tear film parameters had significant differences between the SSDE group and NSSDE group(all P〈0.05). Patients in the SSDE group had significantly lower A1-time and HC-time, but higher DA(P=0.01, 0.02, and 0.02, respectively) compared with the NSSDE group. In the SSDE group, DA was negatively correlated with TBUT(rho=-0.38, P=0.03); HC-time was negatively correlated with CSS(rho=-0.43, P=0.02). In the NSSDE group, HC-time was again negatively correlated with CSS(rho=-0.39, P=0.02).CONCLUSION:There are differences in corneal biomechanical properties between SSDE and NSSDE. The cornea of SSDE tends to show less "stiffness", as seen by a significantly shorter A1-time and HC-time, but larger DA, compared with the cornea of NSSDE. Biomechanical parameters can be influenced by different tear film parameters in both groups.
文摘Neuromyelitis optica spectrum disorder often co-exists with primary Sjogreffs syndrome. We compared the clinical features of 16 neuro- myelitis optica spectrum disorder patients with (n = 6) or without primary Sjogreffs syndrome (n = 10). All patients underwent extensive clinical, laboratory, and MRI evaluations. There were no statistical differences in demographics or first neurological involvement at onset between neuromyelitis optica spectrum disorder patients with and without primary Sjogren's syndrome. The laboratory findings of cerebrospinal fluid oligoclonal banding, serum C-reactive protein, antinudear autoantibody, anti-Sjogren's-syndrome-related antigen A an- tibodies, anti-Sjogren's-syndrome-related antigen B antibodies, and anti-Sm antibodies were significantly higher in patients with primary Sjogren's syndrome than those without. Anti-aquaporin 4 antibodies were detectable in 67% (4/6) of patients with primary Sjogren's syndrome and in 60% (6/10) of patients without primary Sj6gren's syndrome. More brain abnormalities were observed in patients without primary Sj6gren's syndrome than in those with primary Sj6gren's syndrome. Segments lesions (〉 3 centrum) were noted in 50% (5/10) of patients without primary Sj6gren's syndrome and in 67% (4/6) of patients with primary Sjogren's syndrome. These findings indicate that the clinical characteristics of neuromyelitis optica spectrum disorder patients with and without primary Sjogren's syndrome are similar. However, neu- romyelitis optica spectrum disorder patients without primary Sjogreffs syndrome have a high frequency of brain abnormalities.
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OBJECTIVE To study the therapeutic effects of TGP on SS both in C57BL/6J mice immunized by immu⁃nological induction(SS mice)and NOD/ShiltJNju(NOD)mice.METHODS TGP(180,360,720 mg·kg^-1)was intragastri⁃cally administered for 6 or 16 weeks for SS mice and NOD mice,respectively.Weekly food and water intake,saliva flow,submandibular gland(SMG)and spleen index,and SMG pathology were measured.ELISA was used to evaluate serum interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),interferon-γ(IFN-γ)and autoantigens(SSA/Ro,SSB/La,andα-fodrin).Real-time PCR and Luminex liquid suspension chip assay were applied to analyze SMG inflammatory cytokines mRNA TNF-α,IL-17A,CXCL9,CXCL13,and B-cell activating factor(BAFF)and protein(IL-1β,IL-6,TNF-α,and IFN-γ)expres⁃sion.RESULTS Compared with SS mice,TGP(720 mg·kg^-1)treatment increased saliva flow,reduced organ indexes,and decreased serum IL-6 and IFN-γ concentration.TGP(360 mg·kg^-1)treatment decreased serum IFN-γ concentra⁃tion.TGP(180,360,720 mg·kg^-1)treatment improved SMG pathological damage.Compared with NOD mice,the saliva flowincreased from 9 to 15 weeks of administration.After 2 weeks of administration,TGP(720 mg·kg^-1)treatment decreased serum SSA/Ro,SSB/La and a-fodrin concentration,increased SMG index,inhibited SMG IFN-γ concentra⁃tion,and down-regulated SMG TNF-α,IL-17A,CXCL9,CXCL13 and BAFF mRNA expression.TGP(360 mg·kg^-1)treat⁃ment decreased serum SSB/La and a-fodrin,and SMG TNF-α and IFN-γ concentration,and down-regulated SMG TNF-α,IL-17A,CXCL9 and BAFF mRNA expression.TGP(180 mg·kg^-1)treatment decreased serum SSB/La,a-fodrin,and SMG IL-1β concentration,and down-regulated SMG TNF-α,IL-17A and BAFF mRNA expression.After 8 weeks of administration,TGP(180,360,720 mg·kg^-1)treatment increased SMG index,and decreased serum a-fodrin concentra⁃tion.TGP(720 mg·kg^-1)treatment down-regulated mRNA expression of SMG TNF-α,IL-17A,CXCL9,CXCL13,and BAFF.TGP(360 mg·kg^-1)treatment reduced mRNA expression of TNF-α,CXCL9,CXCL13 and BAFF,and concentra⁃tion of IL-6 and TNF-α.TGP(180 mg·kg^-1)treatment down-regulated mRNA expression of TNF-α,CXCL9,and CXCL13,and decreased IL-6 and TNF-αconcentration in SMG.After 16 weeks of administration,TGP(180,360,720 mg·kg^-1)treatment reduced serum SSA/Ro and a-fodrin concentration,increased SMG index,and decreased SMG CXCL13 and BAFF mRNA expression.TGP(360,720 mg·kg^-1)treatment decreased serum SSB/Laconcentration and SMG TNF-α,IL-17A and CXCL9 mRNA expression.Besides,TGP(180,360,720 mg·kg^-1)treatment alleviated the pathological damage of SMG after 2 and 16 weeks of administration.CONCLUSION TGP has a certain therapeutic effect onmice through inhibiting inflammatory responses.
文摘Aim: To elucidate the anti-apoptotic properties of nuclear factor kappa light-chain-enhancer of activated B cells (NF-κB) and feedback regulation of NF-κB by nuclear factor of kappa light-chain-enhancer of activated B-cells inhibitor alpha (IκBα). Methods: We developed an in vitro model of Sjogren’s syndrome by transfecting human salivary gland (HSG) and acinar cells (NS-SV-AC) with a plasmid-encoding IκBαM (pCMV-IκBαM), a degradation-resistant IκBα (nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha)-mutant, and examined TNF-induced apoptosis and anti-apoptotic properties of NF-κB. Apoptosis and induction of pro-apoptotic and anti-apoptotic genes were investigated by cDNA arrays, RT-PCR, electrophoretic mobility shift assays, and western blot. Results: In the presence of NF-κB inhibitors, TNF-induced apoptosis was markedly increased in both salivary gland and acinar cells. Increased caspase-3 activity was present in both HSG and NS-SV-AC cells. IκBαM-transfected salivary gland cells were more sensitive to TNF-induced apoptosis than IκBαM-transfected acinar cells. Transcription of pro-apoptotic genes was confirmed in both HSG and NS-SV-AC cells that were transfected with IκBαM. Results from caspase-3 activity assay confirmed previous experiments showing an apoptotic role for NF-κB. Conclusion: Data from gene expression arrays suggest that different mechanisms may operate during TNF-induced apoptosis in salivary gland ductal and acinar cells.

文摘The recognition of the profound impact of the human gastrointestinal microbiome(GM) on human autoimmune diseases has gradually increased thanks to deeper research efforts. As a systemic autoimmune disease, primary Sjogren’s syndrome(pSS) cannot be completely cured. Human studies have revealed that GM species and diversity are altered in patients with p SS compared with healthy individuals. Animal studies have provided possible mechanisms for the association between pSS and GM. The potential role of GM in pSS is exerted through several mechanisms. GM dysbiosis leads to increased intestinal permeability, which increases the risk of GM antigen exposure and activates specific autoreactive T lymphocytes via “molecular mimicry”. In addition, GM antigen exposure and intestinal immune tolerance loss caused by GM dysbiosis together induce chronic local gut mucosal inflammation, which deteriorates to systemic chronic non-specific inflammation with the circulation of pro-inflammatory lymphocytes and cytokines. These factors eventually activate autoreactive B lymphocytes and lead to pSS. If GM plays a key role in the pathogenesis of pSS, clarifying the underlying mechanisms will be helpful for the development of new therapies targeting GM for dry eye associated with pSS. This review summarizes the latest knowledge about the relationship between GM and p SS,with the aim of contributing to future research and to the development of new clinical applications.

文摘BACKGROUND Sjogren’s syndrome(SS),which affect salivary gland function,is an autoimmune disease.SS may involve extraglandular organs.Approximately 10 to 20 percent of SS patients have clinically significant lung disease,but presentation of pulmonary amylodosis is extremly rare.The incidence of benign monoclonal gammopathy in SS patients is high,but multiple myeloma is rare.No case involving the simultaneous occurrence of two rare diseases,pulmonary amyloidosis and multiple myeloma,in the same patient with SS has been reported so far.CASE SUMMARY A 41-year-old male patient was referred to our hematology department due to incidentally detected gastric plasmacytoma.He had been diagnosed with SS four years earlier.Multiple miliary nodules,ground glass opacity in both lung fields,and enlargement of both inguinal lymph nodes was observed on chest and abdomen computer tomography.Based on the pathological findings of lung and lymph node biopsied specimens,the patient was diagnosed with pulmonary amyloidosis and multiple myeloma.Pulmonary amyloidosis and multiple myeloma associated with SS has rarely been reported.CONCLUSION This is an extremely rare case of simultaneous pulmonary amyloidosis and multiple myeloma in the same patient with SS.
文摘AIM:To focus on different visual resolution tasks under photopic and mesopic conditions in Sjogren’s syndrome patients compared to age-matched healthy controls.METHODS:The visual resolution measurements included high and low visual acuities and contrast sensitivity functions.These tests were conducted under photopic and then mesopic conditions.Twenty-one Sjögren’s syndrome patients and 21 aged-matched healthy volunteers completed all the measurements in this study.RESULTS:Sjogren’s syndrome patients have greater impairment in contrast sensitivity than standardized visual acuity.This reduction was significant under the mesopic condition.Also,Sjogren’s syndrome patients treated with pilocarpine suffer more than patients without pilocarpine treatment under low light conditions.CONCLUSION:Sjogren’s syndrome patients shows greater impairment in different visual resolution tasks due to dry eye symptoms.
文摘Intro: Primary Sjogren’s syndrome is a chronic systemic autoimmune disease. Although ocular and oral dryness are the hallmarks of this syndrome, renal involvement when present most commonly has the histological appearance of tubointerstitial nephritis and less often glomerular involvement. We report, a unique case of renal manifestations of primary Sjogren’s syndrome with a proven histological focal proliferative and crescentric necrotizing glomeru-lonephritis. Case: A 30 years old man with Kimura disease presented with four months of subjective fevers, migrating skin erythema, dry mouth, and dry eyes. On further workup the patient was found to have a positive ANA, positive anti-SSA, and was evaluated by ophthalmology who found keratoconjunctivitis sicca. The patient was started on hydroxychloroquine in combination with prednisone. On follow up, the patient was found to be hypertensive with acute kidney injury, a creatinine of 3.65, proteinuria and hematuria. Renal ultrasound was unremarkable. Cytoplasmic ANCA was positive and kidney biopsy was performed revealing non pauci-immune focal proliferative and necrotizing glomerulonephritis with cellular crescents and mesangial dense deposits by electron microscopy. Conclusion: To our knowledge, the association between biopsy proven focal proliferative and necrotizing glomerulonephritis with primary Sjogren’s syndrome has never been previously described in the literature, nor has there been a reported case of association between Kimura disease, ANCA serology and primary Sjogren’s syndrome.

文摘Sjogren’s syndrome (SS) is a systemic autoimmune disease that affects primarily the lacrimal and salivary glands. In addition to a systemic autoimmune response directed against ubiquitous antigens (such as Ro and La antigens), patients with SS mount a localized response that affects the epithelial component of exocrine glands leading to the establishment of a destructive inflammatory infiltrate comprised of activated T and B cells. Local chemokine and cytokine production drive the recruitment and local activation of immune cells that cause injury to acinar cells. CD4 T cells with different functional differentiation programs including Th1 (IFN-γ), Th2 (IL-13, IL-4) and Th17 (IL-17, IL-21, IL-22) as well as diverse cytokine signaling pathways, are involved at the initiation, perpetuation, and progression of the disease. Which factors initiate this response and allow it to become chronic are unknown. Proposed mecha-nisms include viral infections and acinar cell apoptosis. Moreover risk-conferring genetic variants, probably through the facilitation of innate and adaptive immune activation, most certainly contribute to the creation of an underlying environment that fosters tolerance loss and facilitates perpetuation of the autoimmune response. In this review, we describe the mechanisms through which the immune response causes SS and emphasize the pathways that are amenable of being targeted with therapeutic purposes.
文摘Hypokalemic acidosis can complicate a primary Sjögren’s syndrome. The clinical feature is rarely revealed by manifestations due to hypokalemia. We report the case of a 46-year-old woman, admitted to explore a paresthesia and paresis of inferior limbs. The diagnosis of Sjögren’s syndrome was retained since there was the association of xerophthalmia, sialadenitis at the labial biopsy and positive immunological results (anti-SSA and anti-SSB). The absence of another auto-immune or systemic illness allowed us to consider that the Sjögren’s syndrome was primary. The biological explorations revealed a hyperchloremic and hypokalemic acidosis. The treatment was based on corticosteroid and potassium supplementation. The follow-up was marked by a clinical and biological amelioration.

文摘Background:Sjögren syndrome(SS)is a long-term autoimmune disease that affects the body’s moisture-producing glands.It can occur independently of other health problems(primary disease)or as a result of another connective tissue disorder(secondary disease).Medication is directed at the person’s symptoms.Recently,it is reported that prescription of Chinese medicine has a great effect on SS and reduce adverse drugs reaction,which can provide a more safer treatment to SS.Case presentation:We here report a 43 year-old Chinese patient with continuous immune thrombocytopenia diagnosed as Sjögren syndrome,who was not response to routine medication such as Methylprednisolone and acyclovir.After that,the patient was treated by prescription of Chinese medicine,and the symptoms were improved apparently.We suppose that prescription of Chinese medicine has an unexpected effect on SS,which can alleviate patient’s symptoms.Conclusion:The clinical efficacy of Sjogren syndrome(SS)is effective in the treatment of prescription of Chinese medicine.It can improve patient’s symptoms and reduce adverse drug reactions.
文摘Salts of calcium phosphate and inorganic phosphate are normally found in serum and extracellular fluids, balancing through poorly understood factors that prevent abnormal tissue deposition of these minerals. However, in those tissues that are injured, especially due to chronic inflammatory processes, a predisposition to the deposition of these minerals is developed, triggering what has been called Dystrophic Calcinosis (DC), common in different Connective Tissue Diseases (CTD), especially dermatomyositis and scleroderma, but there is no a frecuent association with diseases like Rheumatoid Arthritis (RA) and Sj?gren Syndrome (SS). We report a case of a female patient of 63 years old with RA and Secundary SS who presents with DC in the hands and no evidence of other connective tissue.
