Cyclophosphamide is one of the key immunosuppressive agents for the management of LN. Leflunomide is an isoxazole immunomodulatory agent has been shown to be safe, well tolerated and effective in SLE and LN. <strong>Objective: </strong>To evaluate the outcome of leflunomide in the treatment of proliferative lupus nephritis compared to cyclophosphamide. <strong>Method: </strong>This randomized clinical trial was held in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2017 to August 2019. A total of 66 patients of proliferative lupus nephritis who need induction therapy were enrolled in this study. Leflunomide 100 mg/day for consecutive 3 days followed by 0.5 mg/kg/day in divided dose was given in experimental group (n = 32) and intravenous cyclophosphamide 0.5 gm/m2 of body surface area monthly pulse was given in control group (n = 34). All study patients have received prednisolone and hydroxychloroquine according to KDIGO guideline then followed up monthly for 6 months. Outcomes were measured at 6th month by renal function [S. Creatinine, 24 hours urinary total protein (24-hr UTP)], changes in SELENA-SLEDAI score, anti-ds DNA level, serum complement levels (serum C3 & C4), remission (complete/partial) and adverse drug responses.<strong> Result:</strong> In experimental group, remission occurred in 18 (56.3%) patients and no remission in 14 (43.7%) patients. In control group, remission occurred in 24 (70.6%) patients and no remission in 10 (29.4%) patients. Adverse effects in experimental group were: elevated ALT (6.3%), hypertension (12.5%), infection (6.3%) and amenorrhea (12.5%). In control group, adverse effects were mainly leucopenia (5.9%), infection (17.7%) and amenorrhea (29.4%). Intergroup analysis for treatment responses and adverse effects showed no significant difference (p > 0.05). <strong>Conclusion:</strong> Leflunomide combined with prednisolone is effective in the induction treatment of proliferative lupus nephritis in Bangladeshi patients in terms of response rate and adverse effects.展开更多

The prevalence of these antibodies in SLE patients at the time of diagnosis is not known in Indian SLE patients. This study was conducted to evaluate the prevalence of ACA and anti-β2GP autoantibodies in SLE patients and to correlate them with disease activity and immune parameters such as C3, C4 and CRP levels. where 85 SLE patients referred from Rheumatology Department, KEM hospital, Mumbai were studied. SLE disease activity was evaluated by SLE Disease Activity Index (SLEDAI) score at the time of evaluation. All patients studied were in an active stage of disease of which 37.6% patients had renal disorders, which were categorized as Lupus Nephritis (LN) and 62.3% patients did not show any renal manifestations (non-LN). ACA and anti-β2GP autoantibodies, to IgG and IgM subclasses were tested by ELISA. C3, C4 and CRP levels were detected by nephelometer. It was observed that 12.9% patients were IgG-ACA and IgM-ACA positive and ACA positivity was noted more among LN group Anti-β2GP autoantibody positivity was 27.1% for IgG and 31.8% for IgM., IgG-anti-β2GP antibodies were slightly higher in non-LN patients, whereas a higher incidence of IgM-anti-β2GP antibodies were detected in LN patients. Hence detection both ACA and anti-β2GP antibodies along with associated immune parameters were helpful to evaluate their possible association with disease severity in SLE patients. A long term follow up of patients having ACA and anti-β2GP antibodies without thrombotic event is also needed to detect their possible thrombotic event in future along with their clinical presentation.展开更多
