Immunoadsorption and plasmapheresis are equally efficacious as adjunctive therapies for severe lupus nephritis

This was a prospective randomized controlled trial to evaluate the effects of immunoadsorption (IA) versus conventional PP (PP) as adjunctive therapy in the treatment of severe lupus nephritis (LN). Of 28 patients with biopsy-proven severe LN (ISN/RPS classes III or IV ± V), 14 underwent 36 sessions of PP and the other 41 sessions of IA in addition to our centers standard LN treatment protocol. Three patients in the PP group and 2 in the IA group experienced a transient, marked drop in platelets with the second session. Except for a higher pre treatment mean SLEDAI score in the PP group 17.4 ± 2.0 vs. 13.5 ± 4.8; p = 0.009 and a serum creatinine of 163 ± 7.9 vs. 81.7 ± 10.2; p = 0.33, there were no other baseline differences. Some differences did exist between the two therapies in the immediate post-treatment phase, at 1 and 3 months. Three in IA relapsed, none of PP in third months, whereas two patients relapsed in the PP and none of IA cohorts at 6 months. However, most of these parameters did not differ by 6 months. The pre- and post-therapy SLEDAI scores remained different 12.4 ± 4.5 vs. 9 ± 4; p = 0.04 at 1 month, and at 3 month 13.5 ± 4.7 vs. 7.7 ± 1.1; p = 0.012 but not at 6 months. We conclude that IA and PP were equally well tolerated and efficacious as adjunctive therapy for severe LN.

Subclinical atherosclerosis among rheumatoid arthritis patients without overt cardiovascular risk factors.

Abstract Objective. To determine the associated factors of subclinical atherosclerosis measured with carotid intima media thickness (CIMT) among rheumatoid arthritis (RA) patients without any overt traditional cardiovascular (CV) risk factors. Methods. Forty RA patients with matched age and gender healthy controls were recruited. Carotid ultrasound was performed to all subjects. CIMT was considered to be abnormally thickened if it was more than the 75th percentile matched for age and sex reference values. Univariate and multivariate analyses were performed to determine the association between the sociodemographics and disease characteristics of RA with thickened CIMT. Results. Abnormally thickened CIMT were observed in 11 RA patients (27.5%) and in 4 control subjects (10%), p = 0.04. It was highly prevalent among RA patients with active disease (54.5% vs 17.2%), p = 0.02. Patients with thickened CIMT also tend to have erosive disease, p = 0.06. Seropositive rheumatoid factor (RF) patients also had significantly higher CIMT values as compared with sero-negative patients, p = 0.03. Multivariable logistic regression analysis revealed that active disease was independently associated with thickened CIMT. Conclusions. RA patients are at risk for subclinical atherosclerosis despite absence of traditional CV risk co morbidities and active disease was the independent factor associated with it.

Steroid‐induced diabetes mellitus in systemic lupus erythematosus patients: analysis from a Malaysian multi‐ethnic lupus cohort

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease and glucocorticoid is the mainstay of treatment in SLE. The reported incidence of steroid‐induced diabetes mellitus (SDM) ranged between 1–53%. We sought to investigate the prevalence and associated factors of SDM in patients with SLE.

Damage in the multiethnic Malaysian systemic lupus erythematosus (SLE) cohort: Comparison with other cohorts worldwide

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease and despite the improvement in the survival in the past few decades, the morbidity due to disease damage remains significant. The objectives of this study were to investigate the disease damagepattern and determine the associated factors of damage in the multi-ethnic Malaysian SLE patients. We consecutively 424SLE patients who attended a consistent follow-up at the National University of Malaysia Medical Centre and Putrajaya Hospital were recruited. Disease damage was assessed using the SLICC/ACR (Systemic Lupus International Collaborating Clinics/American College of Rheumatology) Damage Index (SDI) scores. Information on their demographics and disease characteristics were obtained from the clinical record. Univariate analysis was performed and the best model of independent predictors of disease damage was determined by multivariate logistic regression analysis. A total of 182 patients (42.9%) had disease damage (SDI ≥1). A significantly higher number of Indian patients had disease/organ damage and they predominantly developed steroid-induced diabetes mellitus (SDM). Patients with corticosteroid-induced osteoporosis (CIOP) were more likely to be Malayswhile majority of patients who developed malignancy were Chinese (p<0.05). In the univariate and multivariate analyses, disease damage was significantly associated with age, Indian ethnicity, lower mean cumulative C3 level, neuropsychiatry lupus (NPSLE), and antiphospholipid syndrome (APLS). Patients who had ever and early treatment with hydroxychloroquine(HCQ)were less likely to develop disease damage while more patients who had received oral prednisolone ≥1mg/kg daily over 2 weeks had disease damage (p<0.05). In conclusion, there were inter-ethnic differences in the damage pattern and risks among SLE patients.

Etanercept in the treatment of recalcitrant enteropathic arthritis: a case report

IntroductionEnteropathic arthritis is one of the recognized extraintestinal manifestations of inflammatory bowel disease and affects up to 25% of patients. The treatment options for refractory disease were rather limited and ineffective until the arrival of biologic therapy in the last few years. The use of etanercept was unique for this disease.Case presentationIn this case report, a 58-year-old Malay woman with a 17-year history of ulcerative colitis had persistent left knee effusion and synovitis for seven years, despite remission of the primary disease. She had had multiple courses of systemic and intra-articular steroid that caused significant systemic side effects such as impaired fasting glucose, hypertension, cataract, and weight gain. She also had a total left knee replacement for secondary osteoarthritis. But the left knee synovitis and effusion recurred a month after the total knee replacement, and she was subjected to a total synovectomy the following year. In view of failure of remission despite multiple immunosuppressants (100 mg of azathioprine daily, 1 g of sulfasalazine twice a day, 10 mg of prednisolone daily, and 10 mg of methotrexate weekly), 25 mg of subcutaneous etanercept twice weekly was started. After 5 weeks of treatment, complete resolution of left knee effusion and normalization of the inflammatory markers were shown. This continued up to 12 months of follow-up while our patient was on etanercept and 10 mg of methotrexate weekly. No relapse or serious side effects were noted.ConclusionsThis case demonstrates the efficacy of etanercept in recalcitrant enteropathic arthritis with no relapse of the underlying colitis while on treatment. The usage of this tumor necrosis factor inhibitor was unique in this case of rheumatology and gastroenterology.

Risk of upper gastrointestinal adverse events in Malaysian rheumatic patients on long-term non-steroidal antiinflammatorydrugs

Background: Non-steroidal anti-inflammatory drug (NSAID)-induced upper gastrointestinal (GI) adverse events are well-described in the Western population but data is lacking in Asian patients. This study aims to describe the incidence and predictive factors for NSAID-induced upper GI complications in a cohort of multi-ethnic patients in Malaysia. Methods and Findings: A retrospective cohort study was conducted in adult patients with rheumatoid arthritis (RA) and/or osteoarthritis (OA) from 2010-2013 in four main rheumatology centres in Malaysia with computerized clinical and pharmaceutical records. Clinical, pharmaceutical and demographic data over a 24-months follow-up period were analysed in subjects who were prescribed long-term NSAID therapy (defined as a minimum duration of four weeks). 634 patients were included in the final analysis with the following characteristics: mean age 53.4 ± 12.5 years, 89.9% female, diagnosis: RA 59.5%, OA 10.2% and RA/OA combination 30.3%. 371 (58.5%) patients received non-selective NSAIDs and 263 (41.5%) patients received COX-2 inhibitors. There were a total of 84 GI adverse events during the period of study, giving an incidence rate of 66.2 per 1000 person-years and a risk of 13.2%. The majority of upper GI adverse events was dyspepsia (92.9%), and only 7.1% with peptic ulcer disease/ upper GI bleeding. Multivariate analysis showed that the only independent predictive factor of upper GI adverse event in this cohort was a history of upper GI disease (O.R. 2.073, 95% C.I. 1.029 – 4.176). COX-2 inhibitor showed a trend towards, but not independently predictive of, GI protection in this analysis (OR 0.643; 95% C.I. 0.397 – 1.043). Conclusion: Malaysian rheumatic patients on long-term NSAID therapy, managed at referral centres, have a 13.2% risk of upper GI adverse events, with dyspepsia being the commonest complication. Patients with a history of upper GI disease were twice as likely to develop further upper GI adverse events with the use of long-term NSAIDs.

Juvenile spondyloarthropathy: an important clinical lesson to remember

Spondyloarthropathy (SpA) is a group of inflammatory conditions that include spondylitis, sacroiliitis, asymmetrical peripheral arthritis and enthesitis. This condition is known as juvenile SpA when the diagnosis is made in patients up to 16 years of age. Enthesitis is a highly specific feature that occurs more often in juvenile SpA than in the adult form. In contrast to adult onset SpA, the initial manifestation of juvenile SpA rarely presents as inflammatory back pain. Peripheral arthritis is the more common presenting feature. We report a case of a 12-year-old boy who presented with a 1-year history of progressive low back pain, gluteal pain and thigh pain. There were no clinical symptoms of arthropathy of the distal extremities. MRI of the whole spine was performed twice, which, unfortunately, was unyielding. Finally, MRI of the sacroiliac joints revealed asymmetric sacroiliitis as well as enthesitis of the hips and pelvis. Further laboratory data showed negative rheumatoid factor and positive human leucocyte antigen (HLA) B27. A diagnosis of juvenile SpA with sacroiliitis and enthesitis was made. The imaging characteristics of juvenile SpA are highlighted.

Unusual association of diseases/symptoms: Sweet’s syndrome in Crohn’s colitis

We would like to report a case involving a 38-year-old woman who presented with knee and ankle swellings 2 weeks prior to admission. There were also multiple painful oral ulcers and a few skin sores on the wrist. She also had associated diarrhoea for 2 weeks. There was also marked loss of weight (6 kg in 2 weeks). Colonoscopy examination showed macroscopic and histopathological findings of Crohn’s disease; however, skin histology showed extensive neutrophilic infiltration in the dermis, predominantly in the perivascular region. Her final diagnosis was Sweet’s syndrome with Crohn’s disease.
