The symptoms did not resolve with standard treatments(nonsteroidal anti-inflammatory drugs, steroids and methotrexate). TNF-alpha inhibitors(certolizumab pegol and adalimumab) were added to the treatment regime, with some adverse effects. A trial of human umbilical cord stem cell therapy was then initiated. The stem cells were enriched and concentrated from whole cord blood, by removal of erythrocytes and centrifugation. The patient received several infusions of cord blood stem cells, through intravenous and intra-articular injections. These stem cell treatments correlated with remission of symptoms(joint pain and psoriatic plaques) and normalized serologic results for the inflammatory markers C-reactive protein and erythrocyte sedimentation rate. These improvements were noted within the first thirty days post-treatment, and were sustained for more than one year. The results of this trial suggest that cord blood stem cells may have important therapeutic value for patients with psoriatic arthritis, particularly for those who cannot tolerate standard treatments.展开更多

Methods: Participating rheumatologists each performed a chart audit on 20 patients with PsA and SpA. Accredited education (determined by a survey and chart audits) and results of chart audits (comparing to other rheumatologists) were provided for each participant (intervention). Eight months later, a repeat chart audit by each participant was conducted on another 20 PsA and SpA patients. Changes in measurements collected, treatment given and patient characteristics pre and post intervention were analyzed. Results: Nine rheumatologists received the intervention. At baseline, most routinely monitored PsA and SpA for clinical and laboratory markers. In PsA, there was no change post-intervention in performing SJC (96%), TJC (≥91%), ESR (≥70%), CRP (≥73%), and CDAI (25%). In SpA, there were increased measurements of inflammatory markers (54% pre vs. 61% post for CRP), more NSAID use and decreased physical exam measures and HAQ but no significant changes. There were no major treatment differences pre and post intervention including NSAIDs, DMARDs and biologics. Conclusions: The rheumatologists frequently performed measurements of disease activity, did not change significantly with educational intervention so there may have been little room for improvement and many patients were already in a low disease state. Calculation of composite scores did not increase in PsA. The validity of physical exam and BASDAI as a measurement of disease activity were noted as concerns in applying a treat-to-target approach in SpA. Significance and Innovation: This study did not show a significant change in behavior for rheumatologists who had education based on care gaps and needs assessment in psoriatic arthritis and spondyloarthropathy. The rheumatologists identified that disease activity is difficult to determine with usual care in SpA and thought some measures lacked validity.展开更多

PsA patients may present a wide range of clinical manifestations including skin and nail abnormalities. Indeed, articular involvement is variable too. Disease development relies on a heterogeneous net made of multiple cytokines pathways which are regulated by several factors including human leucocyte antigen (HLA) expression, miRNAs, microbiome. Among genetic polymorphisms which can lead to abnormal cytokine expression, tumor necrosis factor (TNF) polymorphisms have been studied. Thus, leading to the development of new therapeutic agents. Finally, further studies on genetic factors and epigenetics will give new insights into this complex disorder. The aim of this mini-review is to provide the reader with a summary of the fundamental and most innovative aspects of genetic and epigenetic factors involved in the PsA, thus including human leucocyte antigen (HLA) expression, tumor necrosis factor (TNF) polymorphisms, micro RNAs and microbiome.展开更多

Studies for this group of patients are lacking. Method: Qualitative in terviews were conducted with ten informants after hydrotherapy treatment. The treatment included exercises for increased mobility, coordination, endurance, aerobic fitness, stretching and relaxation. The interviews were analysed with content analysis. Results: A theme “hydrotherapy—a multidimensional experience” and two categories emerged: situational factors and effects of hydrotherapy. The category “situ- ational factors” comprised the subcategories: warm water, training factors and a competent instructor, and the category “effects of hydro- therapy” comprised the subcategories: psy- chological effects, improved physical capacity, social effects, changed pain experience and changes in work and participation in daily life. Conclusion: Positive effects of regular hydro- therapy in a group setting were shown in physical ability, energy, sleep, cognitive function, work and participation in daily life. The instruc- tors had an important coaching role, which needs to be promoted.展开更多

This was a case-control study. The case group consisted of six individual educational sessions delivered by a nurse. A total of 40 patients with PsA joined in this study: the case group (n = 20) and the control group (n = 18). After a 6-week intervention, the case group had significantly better management for the severity of arthritis symptoms (p < 0.05), better psychological well-being and significant lower levels of anxiety (p < 0.05), and depression score (p < 0.01), and reported better improvement of physical and psychological domain of quality of life (QOL) (both p values < 0.05) than the control group. In conclusion, this nurse-led individual education intervention has statistically significant benefits for the management of clinical symptoms of arthritis and for psychological well-being and QOL in patients with PsA.展开更多

ALL patients may present with isolated and persistent osteo-articular complaints, lower incidence of hepatomegaly, splenomegaly or lymphadenopathy without clear laboratory features, and misdiagnosed as systemic juvenile idiopathic arthritis (sJIA). Methods: This was a single center cross sectional study over a period of 4 years. Clinic laboratory profiles of 39 ALL children were compared with 39 age and sex-matched sJIA cases. Result: Among 39 ALL patients 89.7% were initially misdiagnosed as sJIA upon clinical presentation. Majority (66.7%) of ALL patients had oligo-articular joint involvement. In sJIA, small joints of the hands were most commonly involved. The total WBC count was significantly higher in ALL patients (p-value 0.0065). CRP and LDH values between the two groups showed significant differences (p-value 0.00006 and 0.00001 respectively). Conclusion: The presentation of leukemia with arthralgia or arthritis makes the diagnosis difficult for the physicians. The diagnosis of sJIA must be made with caution keeping the possibility of haematological malignancy in mind.展开更多

It is associated with abnormal levels of serum zinc (Zn) and copper (Cu) as during inflammation serum copper concentration increases and zinc decreases. Objective: To assess the serum Zn and Cu levels in different sub-types of JIA patients and their correlation with the disease duration. Methods: This cross-sectional study was conducted over twelve months at the Pediatric Rheumatology Division, Department of Paediatrics, Bangabandhu Sheikh Mujib Medical University. Sixty-nine JIA cases that fulfilled the International League of Association for Rheumatology (ILAR) criteria were taken as cases and age and sex-matched healthy children were considered as controls. The serum Zn and Cu tests were done using the spectrophotometric method with INDIKO PLUS Drug Analyzer. Data were recorded in a pre-designed questionnaire. Data were checked, verified and analyzed manually where continuous variables were analyzed using unpaired t-test and categorical variables using the ANOVA test. Pearson’s correlation coefficient test was used to see the correlation of serum zinc and copper levels with disease duration. Results: Boys were predominant in both case and control groups, with the majority within the 10 to 16-year-age group. Enthesitis-related arthritis (ERA) was the most common subtype followed by sJIA, Oligo JIA, Poly JIA (RF-) and unclassified subtypes. Disease duration was found less than 12 months in 30.4% of JIA patients. Serum analysis revealed a statistically significant reduction in mean zinc levels and increased copper levels in JIA patients compared to controls. This study observed a negative correlation between serum zinc levels and disease duration, whereas serum copper levels exhibited a positive correlation with disease duration. Conclusion: In conclusion, this study revealed that JIA patients exhibit alterations in serum zinc and copper levels. Serum copper levels showed a positive correlation and serum zinc levels showed a negative correlation with the duration of the disease.展开更多

Throughout the world, 287 cases of Rhupus have been described. We report two new observations of two patients who presented predominantly distal erosive polyarthritis with positive anti-Sm antibodies in one case and SmRNP in the other case. Observations: Case 1: 37 years old patient, with a recent diagnosis of pulmonary tuberculosis. She has since 8 months an inflammatory, bilaterally and symmetrical polyarthralgia without deformation or ankylosing synovitis, associated with malar erythema without other abnormalities. Immunological tests showed: positive Rheumatoid factor at 158 IU/ml, positive Anti-CCP at 550 IU/ml, and positivity of antinuclear at 1/1280 nuclear fluorescence with a strong presence of anti-Sm >8 IU/ml. The diagnosis of rhupus was concluded, without serious visceral involvement. Case 2: A 28-year-old patient, married with 3 children, with bilateral, symmetrical, deforming and chronic polyarthritis affecting large and small joints, which had been evolving for over 5 years without cutaneous abnormality associated. Paraclinical investigations showed: a biological inflammatory syndrome. Immunology was positive, with rheumatoid factors at 78 IU/ml, anti-CCP at 561 IU/ml, antinuclear antibodies at 1/1280 with positive anti-SmRNP and anti-SSA/Ro52, and a positive direct Coombs test. Joint ultrasound revealed tenosynovitis of the extensors and common flexors of the fingers, erosions and synovitis of multiple PPIs. The diagnosis of rhupus was based on the presence of 10 ACR criteria for RA and 8 ACR/EULAR 2019 criteria for SLE. Conclusion: Rheumatoid arthritis is a rare autoimmune disease combining features of both systemic lupus erythematosus and rheumatoid arthritis in the same patient, often sequentially. Despite a growing number of case reports and series, a consensus on the classification of SLE arthritis is still lacking, and diagnostic criteria for rhupus do not exist. These cases of rhupus must be recognized, as the vital and/or functional prognosis may be different from SLE alone or isolated RA.展开更多

In the era of biotherapies and the arrival of biosimilars in sub-Saharan Africa, the objective of this study was to describe plasma IL-6 variations in RA patients at Cité Verte District Hospital (Cameroon). Material and Methods: Descriptive and analytical cross-sectional study from December 1, 2021 to May 31, 2022. We included patients over 18 years old suffering from RA (ACR/EULAR 2010). Patients with an infection were not included. The data collected were age, sex, smoking status, family history, disease duration, disease activity by DAS28, CRP, rheumatoid factor, and plasma level of IL-6. Bone erosion was sought on radiography and ultrasound. Result: We included 31 patients, 25 of whom were women (80.6%). The mean age was 47.27 ± 17.97 years. Disease activity was predominantly moderate (32.3%) and severe (32.3%). Mean IL-6 level was 15.29 ± 2.36 pg/ml (extremes: 11.26 pg/ml and 20.15 pg/ml). IL-6 levels were higher in patients with a history of smoking. Similarly, IL-6 levels were higher in patients with mildly active RA in remission than in moderately and severely active RA. Mean IL-6 levels were significantly higher in patients with erosive RA (16.3 pg/ml VS 14.6 pg/ml). Conclusion: IL-6 levels were significantly elevated in men, weaned smokers and patients with bone erosions.展开更多

文摘BACKGROUND Immune checkpoint inhibitor(ICI)-induced rheumatic immune-related adverse events(ir AEs)have been infrequently reported,and the treatment of severe or refractory arthritis as ir AEs has not been established yet.CASE SUMMARY The patient was a 67-year-old man with a history of well-controlled foot psoriasis who presented with polyarthralgia.He had received pembrolizumab for metastatic gastric adenocarcinoma 2 mo previously.Physical examination revealed erythematous swelling in the distal interphalangeal joints,left shoulder,and both knees.He had plaque psoriasis with psoriatic nail dystrophy and dactylitis in the distal joints of the fingers and toes.Inflammatory markers including C-reactive protein and erythrocyte sedimentation rate were elevated but rheumatoid factor and anticyclic citrullinated peptide antibody were negative.The patient was diagnosed with psoriatic arthritis(PsA)and started on methylprednisolone 1 mg/kg/day after pembrolizumab discontinuation.However,despite 1 wk of methylprednisolone treatment,PsA worsened;hence,leflunomide and methotrexate were started.After 4 wk of steroid treatment,PsA worsened and improved repeatedly with steroid tapering.Therefore,the therapy was intensified to include etanercept,a tumor necrosis factor inhibitor,which ultimately resulted in adequate PsA control.CONCLUSION This is the first report of ICI-induced PsA in a gastric cancer patient.Some rheumatic ir AEs with refractory severe arthritis may require disease-modifying anti-rheumatic drugs and long-term management.
文摘Clinical and laboratory results document psoriatic arthritis in a 56-year old patient. The symptoms did not resolve with standard treatments(nonsteroidal anti-inflammatory drugs, steroids and methotrexate). TNF-alpha inhibitors(certolizumab pegol and adalimumab) were added to the treatment regime, with some adverse effects. A trial of human umbilical cord stem cell therapy was then initiated. The stem cells were enriched and concentrated from whole cord blood, by removal of erythrocytes and centrifugation. The patient received several infusions of cord blood stem cells, through intravenous and intra-articular injections. These stem cell treatments correlated with remission of symptoms(joint pain and psoriatic plaques) and normalized serologic results for the inflammatory markers C-reactive protein and erythrocyte sedimentation rate. These improvements were noted within the first thirty days post-treatment, and were sustained for more than one year. The results of this trial suggest that cord blood stem cells may have important therapeutic value for patients with psoriatic arthritis, particularly for those who cannot tolerate standard treatments.

文摘Leptin,an adipokine responsible for body weight regulation,may be involved in pathological processesrelated to inflammation in joint disorders including rheumatoid arthritis(RA),osteoarthritis,and psoriatic arthritis(PsA).These arthropathies have been associated with a wide range of systemic and inflammatory con-ditions including cardiovascular disease,obesity,and metabolic syndrome.As a potent mediator of immune responses,leptin has been found in some studies to play a role in these disorders.Furthermore,current potent biologic treatments effectively used in Ps A including ustekinumab(an interleukin 12/23 blocker) and ada-limumab(a tumor necrosis factor-alpha blocker also used in RA) have been found to increase leptin receptor expression in human macrophages.This literature review aims to further investigate the role leptin may play in the disease activity of these arthropathies.
文摘Objectives: To determine if comparative practice data and education for rheumatologists would change physician behavior for monitoring and treating psoriatic arthritis (PsA) and spondyloarthritis (SpA). Methods: Participating rheumatologists each performed a chart audit on 20 patients with PsA and SpA. Accredited education (determined by a survey and chart audits) and results of chart audits (comparing to other rheumatologists) were provided for each participant (intervention). Eight months later, a repeat chart audit by each participant was conducted on another 20 PsA and SpA patients. Changes in measurements collected, treatment given and patient characteristics pre and post intervention were analyzed. Results: Nine rheumatologists received the intervention. At baseline, most routinely monitored PsA and SpA for clinical and laboratory markers. In PsA, there was no change post-intervention in performing SJC (96%), TJC (≥91%), ESR (≥70%), CRP (≥73%), and CDAI (25%). In SpA, there were increased measurements of inflammatory markers (54% pre vs. 61% post for CRP), more NSAID use and decreased physical exam measures and HAQ but no significant changes. There were no major treatment differences pre and post intervention including NSAIDs, DMARDs and biologics. Conclusions: The rheumatologists frequently performed measurements of disease activity, did not change significantly with educational intervention so there may have been little room for improvement and many patients were already in a low disease state. Calculation of composite scores did not increase in PsA. The validity of physical exam and BASDAI as a measurement of disease activity were noted as concerns in applying a treat-to-target approach in SpA. Significance and Innovation: This study did not show a significant change in behavior for rheumatologists who had education based on care gaps and needs assessment in psoriatic arthritis and spondyloarthropathy. The rheumatologists identified that disease activity is difficult to determine with usual care in SpA and thought some measures lacked validity.
文摘Psoriatic arthritis (PsA) is a complex immune-mediated disease and its pathogenesis depends both on genetic factors and environment. PsA patients may present a wide range of clinical manifestations including skin and nail abnormalities. Indeed, articular involvement is variable too. Disease development relies on a heterogeneous net made of multiple cytokines pathways which are regulated by several factors including human leucocyte antigen (HLA) expression, miRNAs, microbiome. Among genetic polymorphisms which can lead to abnormal cytokine expression, tumor necrosis factor (TNF) polymorphisms have been studied. Thus, leading to the development of new therapeutic agents. Finally, further studies on genetic factors and epigenetics will give new insights into this complex disorder. The aim of this mini-review is to provide the reader with a summary of the fundamental and most innovative aspects of genetic and epigenetic factors involved in the PsA, thus including human leucocyte antigen (HLA) expression, tumor necrosis factor (TNF) polymorphisms, micro RNAs and microbiome.
文摘Purpose: To describe how patients living with psoriatic arthritis experience long-term hydrotherapy group treatment. Studies for this group of patients are lacking. Method: Qualitative in terviews were conducted with ten informants after hydrotherapy treatment. The treatment included exercises for increased mobility, coordination, endurance, aerobic fitness, stretching and relaxation. The interviews were analysed with content analysis. Results: A theme “hydrotherapy—a multidimensional experience” and two categories emerged: situational factors and effects of hydrotherapy. The category “situ- ational factors” comprised the subcategories: warm water, training factors and a competent instructor, and the category “effects of hydro- therapy” comprised the subcategories: psy- chological effects, improved physical capacity, social effects, changed pain experience and changes in work and participation in daily life. Conclusion: Positive effects of regular hydro- therapy in a group setting were shown in physical ability, energy, sleep, cognitive function, work and participation in daily life. The instruc- tors had an important coaching role, which needs to be promoted.

文摘[Objectives]To study the effect and mechanism of baicalin on the activation of NLRP3 inflammasome in human fibroblast like synoviocytes of rheumatoid arthritis(HFLS-RA).[Methods]To confirm that baicalin alleviated the activation of NLRP3 inflammasome in HFLS-RA,the expression of NLRP3 before and after baicalin treatment was observed by immunofluorescence.Western blot was used to detect the protein expression of p-PI3K,p-Akt,NF-κB p65,NLRP3,ASC and caspase-1 after baicalin treatment for 48 h,and the contents of IL-1 and IL-18 in the supernatents were detected by ELISA.In order to explore the mechanism of baicalin alleviating the activation of NLRP3 inflammasome,the corresponding relationship between let-7i-3p and PIK3CA was verified by double luciferin and Westen blot analysis.The expression of let-7i-3p and PI3K before and after baicalin intervention was detected by RT-qPCR.let-7i-3p interference was used to verify whether baicalin mitigated the activation of enhanced NLRP3 inflammasome.[Results]Baicalin(50 and 100 mg/L)significantly reduced the activation of NLRP3 inflammasome,inhibited the protein expressions of p-PI3K,p-Akt,NF-κB p65,NLRP3,ASC and caspase-1,and the secretion of IL-1 and IL-18.let-7i-3p and PIK3CA had a targeted correspondence,and baicalin up-regulated the expression of let-7i-3p and down-regulated the expression of PIK3CA.Baicalin attenuated the activation of NLRP3 inflammasome enhanced by let-7i-3p interference.[Conclusions]Baicalin can up-regulate let-7i-3p expression,inhibit PI3K/Akt/NF-κB signal transduction,and thus reduce the activation of NLRP3 inflammasome in HFLS-RA.
文摘The aim of this study was to evaluate the effect of an individual nurse-led educational intervention for patients with psoriatic arthritis (PsA). This was a case-control study. The case group consisted of six individual educational sessions delivered by a nurse. A total of 40 patients with PsA joined in this study: the case group (n = 20) and the control group (n = 18). After a 6-week intervention, the case group had significantly better management for the severity of arthritis symptoms (p < 0.05), better psychological well-being and significant lower levels of anxiety (p < 0.05), and depression score (p < 0.01), and reported better improvement of physical and psychological domain of quality of life (QOL) (both p values < 0.05) than the control group. In conclusion, this nurse-led individual education intervention has statistically significant benefits for the management of clinical symptoms of arthritis and for psychological well-being and QOL in patients with PsA.

文摘Rheumatoid arthritis(RA)is a systemic autoimmune disease that is primarily manifested as synovitis and polyarticular opacity and typically leads to serious joint damage and irreversible disability,thus adversely affecting locomotion ability and life quality.Consequently,good prognosis heavily relies on the early diagnosis and effective therapeutic monitoring of RA.Activatable fluorescent probes play vital roles in the detection and imaging of biomarkers for disease diagnosis and in vivo imaging.Herein,we review the fluorescent probes developed for the detection and imaging of RA biomarkers,namely reactive oxygen/nitrogen species(hypochlorous acid,peroxynitrite,hydroxyl radical,nitroxyl),pH,and cysteine,and address the related challenges and prospects to inspire the design of novel fluorescent probes and the improvement of their performance in RA studies.
文摘Background: Acute lymphoblastic leukemia (ALL), the most common paediatric malignancy, is a heterogeneous hematologic disease. ALL patients may present with isolated and persistent osteo-articular complaints, lower incidence of hepatomegaly, splenomegaly or lymphadenopathy without clear laboratory features, and misdiagnosed as systemic juvenile idiopathic arthritis (sJIA). Methods: This was a single center cross sectional study over a period of 4 years. Clinic laboratory profiles of 39 ALL children were compared with 39 age and sex-matched sJIA cases. Result: Among 39 ALL patients 89.7% were initially misdiagnosed as sJIA upon clinical presentation. Majority (66.7%) of ALL patients had oligo-articular joint involvement. In sJIA, small joints of the hands were most commonly involved. The total WBC count was significantly higher in ALL patients (p-value 0.0065). CRP and LDH values between the two groups showed significant differences (p-value 0.00006 and 0.00001 respectively). Conclusion: The presentation of leukemia with arthralgia or arthritis makes the diagnosis difficult for the physicians. The diagnosis of sJIA must be made with caution keeping the possibility of haematological malignancy in mind.

文摘Rheumatoid Arthritis(RA)is an autoimmune disorder that hinders the normal functioning of bones and joints and reduces the quality of human life.Every year,millions of people are diagnosed with RA worldwide,particularly among elderly individuals and women.Therefore,there is a global need to develop new biomaterials,medicines and therapeutic methods for treating RA.This will improve the Healthcare Access and Quality Index and also relieve administrative and financial burdens on healthcare service providers at a global scale.Hydrogels are soft and cross-linked polymeric materials that can store a chunk of fluids,drugs and biomolecules for hydration and therapeutic applications.Hydrogels are biocompatible and exhibit excellent mechanical properties,such as providing elastic cushions to articulating joints by mimicking the natural synovial fluid.Hence,hydrogels create a natural biological environment within the synovial cavity to reduce autoimmune reactions and friction.Hydrogels also lubricate the articulating joint surfaces to prevent degradation of synovial surfaces of bones and cartilage,thus exhibiting high potential for treating RA.This work reviews the progress in injectable and implantable hydrogels,synthesis methods,types of drugs,advantages and challenges.Additionally,it discusses the role of hydrogels in targeted drug delivery,mechanistic behaviour and tribological performance for RA treatment.
文摘Amultifunctional liposomal polydopamine nanoparticle(MPM@Lipo)was designed in this study,to combine chemotherapy,photothermal therapy(PTT)and oxygen enrichment to clear hyperproliferating inflammatory cells and improve the hypoxic microenvironment for rheumatoid arthritis(RA)treatment.MPM@Lipo significantly scavenged intracellular reactive oxygen species and relieved joint hypoxia,thus contributing to the repolarization of M1 macrophages into M2 phenotype.Furthermore,MPM@Lipo could accumulate at inflammatory joints,inhibit the production of inflammatory factors,and protect cartilage in vivo,effectively alleviating RA progression in a rat adjuvant-induced arthritis model.Moreover,upon laser irradiation,MPM@Lipo can elevate the temperature to not only significantly obliterate excessively proliferating inflammatory cells but also accelerate the production of methotrexate and oxygen,resulting in excellent RA treatment effects.Overall,the use of synergistic chemotherapy/PTT/oxygen enrichment therapy to treat RA is a powerful potential strategy.

文摘Rheumatoid arthritis(RA)is a prevalent autoimmune disease whose main features include chronic synovial inflammation,bone destruction,and joint degeneration.Neutrophils are often considered to be the first responders to inflammation and are a key presence in the inflammatory milieu of RA.Neutrophil extracellular traps(NETs),a meshwork of DNA-histone complexes and proteins released by activated neutrophils,are widely involved in the pathophysiology of autoimmune diseases,especially RA,in addition to playing a key role in the neutrophil innate immune response.NETs have been found to be an important source of citrullinated autoantigen antibodies and inflammatory factor release,which can activate RA synovial fibroblasts(FLS)and cause joint damage.This article reviews the role of NETs in the pathophysiology of RA,demonstrating the application of multiple molecules with various therapies,with a view to informing the discovery and development of novel biomarkers and therapeutic targets for RA.
文摘Background: Juvenile Idiopathic Arthritis (JIA) is the most prevalent rheumatic disease in children. It is associated with abnormal levels of serum zinc (Zn) and copper (Cu) as during inflammation serum copper concentration increases and zinc decreases. Objective: To assess the serum Zn and Cu levels in different sub-types of JIA patients and their correlation with the disease duration. Methods: This cross-sectional study was conducted over twelve months at the Pediatric Rheumatology Division, Department of Paediatrics, Bangabandhu Sheikh Mujib Medical University. Sixty-nine JIA cases that fulfilled the International League of Association for Rheumatology (ILAR) criteria were taken as cases and age and sex-matched healthy children were considered as controls. The serum Zn and Cu tests were done using the spectrophotometric method with INDIKO PLUS Drug Analyzer. Data were recorded in a pre-designed questionnaire. Data were checked, verified and analyzed manually where continuous variables were analyzed using unpaired t-test and categorical variables using the ANOVA test. Pearson’s correlation coefficient test was used to see the correlation of serum zinc and copper levels with disease duration. Results: Boys were predominant in both case and control groups, with the majority within the 10 to 16-year-age group. Enthesitis-related arthritis (ERA) was the most common subtype followed by sJIA, Oligo JIA, Poly JIA (RF-) and unclassified subtypes. Disease duration was found less than 12 months in 30.4% of JIA patients. Serum analysis revealed a statistically significant reduction in mean zinc levels and increased copper levels in JIA patients compared to controls. This study observed a negative correlation between serum zinc levels and disease duration, whereas serum copper levels exhibited a positive correlation with disease duration. Conclusion: In conclusion, this study revealed that JIA patients exhibit alterations in serum zinc and copper levels. Serum copper levels showed a positive correlation and serum zinc levels showed a negative correlation with the duration of the disease.
文摘Introduction: The association of systemic lupus erythematosus and rheumatoid arthritis (rhupus) is a rare clinical condition. Throughout the world, 287 cases of Rhupus have been described. We report two new observations of two patients who presented predominantly distal erosive polyarthritis with positive anti-Sm antibodies in one case and SmRNP in the other case. Observations: Case 1: 37 years old patient, with a recent diagnosis of pulmonary tuberculosis. She has since 8 months an inflammatory, bilaterally and symmetrical polyarthralgia without deformation or ankylosing synovitis, associated with malar erythema without other abnormalities. Immunological tests showed: positive Rheumatoid factor at 158 IU/ml, positive Anti-CCP at 550 IU/ml, and positivity of antinuclear at 1/1280 nuclear fluorescence with a strong presence of anti-Sm >8 IU/ml. The diagnosis of rhupus was concluded, without serious visceral involvement. Case 2: A 28-year-old patient, married with 3 children, with bilateral, symmetrical, deforming and chronic polyarthritis affecting large and small joints, which had been evolving for over 5 years without cutaneous abnormality associated. Paraclinical investigations showed: a biological inflammatory syndrome. Immunology was positive, with rheumatoid factors at 78 IU/ml, anti-CCP at 561 IU/ml, antinuclear antibodies at 1/1280 with positive anti-SmRNP and anti-SSA/Ro52, and a positive direct Coombs test. Joint ultrasound revealed tenosynovitis of the extensors and common flexors of the fingers, erosions and synovitis of multiple PPIs. The diagnosis of rhupus was based on the presence of 10 ACR criteria for RA and 8 ACR/EULAR 2019 criteria for SLE. Conclusion: Rheumatoid arthritis is a rare autoimmune disease combining features of both systemic lupus erythematosus and rheumatoid arthritis in the same patient, often sequentially. Despite a growing number of case reports and series, a consensus on the classification of SLE arthritis is still lacking, and diagnostic criteria for rhupus do not exist. These cases of rhupus must be recognized, as the vital and/or functional prognosis may be different from SLE alone or isolated RA.
文摘Introduction: Rheumatoid arthritis (RA) is a chronic, erosive and deforming inflammatory rheumatic disease. In the era of biotherapies and the arrival of biosimilars in sub-Saharan Africa, the objective of this study was to describe plasma IL-6 variations in RA patients at Cité Verte District Hospital (Cameroon). Material and Methods: Descriptive and analytical cross-sectional study from December 1, 2021 to May 31, 2022. We included patients over 18 years old suffering from RA (ACR/EULAR 2010). Patients with an infection were not included. The data collected were age, sex, smoking status, family history, disease duration, disease activity by DAS28, CRP, rheumatoid factor, and plasma level of IL-6. Bone erosion was sought on radiography and ultrasound. Result: We included 31 patients, 25 of whom were women (80.6%). The mean age was 47.27 ± 17.97 years. Disease activity was predominantly moderate (32.3%) and severe (32.3%). Mean IL-6 level was 15.29 ± 2.36 pg/ml (extremes: 11.26 pg/ml and 20.15 pg/ml). IL-6 levels were higher in patients with a history of smoking. Similarly, IL-6 levels were higher in patients with mildly active RA in remission than in moderately and severely active RA. Mean IL-6 levels were significantly higher in patients with erosive RA (16.3 pg/ml VS 14.6 pg/ml). Conclusion: IL-6 levels were significantly elevated in men, weaned smokers and patients with bone erosions.
