简要总结
Erythema Nodosum Leprosum (ENL) is a painful, debilitating complication of leprosy. Patients often require high doses of corticosteroids for prolonged periods. Thalidomide is expensive and not available in most countries. The use of corticosteroids for long periods is associated with adverse effects and mortality. It is a priority to identify alternative agents to treat ENL. Methotrexate (MTX) is a cheap, widely used medication which has been reported to be effective in ENL resistant to steroids and thalidomide.
详细描述
This is a double blind randomized controlled trial (RCT) to test the efficacy of MTX for managing ENL. Patients diagnosed with moderate or severe ENL at ENLIST Group centres in Bangladesh, Brazil, Ethiopia, India, Indonesia and Nepal will be randomly allocated to receive a 15 or 20 mg of oral MTX each week for 48 weeks and prednisolone 40 mg per day reducing to zero over 20 weeks. The control group will receive an identical prednisolone scheme. The participants will be stratified into two groups, those with acute ENL, those with chronic/recurrent ENL. The interventions for both populations are the same, although analysed separately. Adverse effects (AE) will be closely monitored clinically and using laboratory tests. Participants will receive folic acid, 5mg daily for 52 weeks except on the day of MTX to prevent AEs, and nausea will be managed with ondansetron.

研究组 & 干预措施
control
Participants will receive placebo+ prednisolone. Participants will start receiving 4 dummy tablets per week, than participants weighing less than 60 kg will receive 6 dummy tablets from week 8. The placebo will be prescribe weekly. Participants weighing 60 kg or more will receive 8 dummy tablets from week 8. Participants will receive dummy tablets for 52 weeks. Along with prednisolone. The start dose of prednisolone will be 40 mg per day decreasing dosage for 20 weeks.
干预措施: Placebo (Drug)

The placebo will be prescribe weekly. Participants weighing 60 kg or more will receive 8 dummy tablets from week 8. Participants will receive dummy tablets for 52 weeks. Along with prednisolone. The start dose of prednisolone will be 40 mg per day decreasing dosage for 20 weeks.
干预措施: Prednisolone (Drug)
intervention
Participants will receive Methotrexate(MTX)+prednisolone. All participants in intervention arm will receive an initial dose of MTX 10 mg. The MTX will be increased to 15 mg the following week. Participants weighing less than 60 kg will continue to receive 15 mg of MTX weekly thereafter. Individuals weighing 60 kg or more will receive MTX 20 mg from week 8. At week 48 the MTX will be reduced to 10 mg for two weeks followed by 5 mg for two weeks and then stopped. In total participants will receive 52 weeks of MTX along side prednisolone, which will be the same as the control arm.

时间窗: During first 48 weeks
Proportion of individuals who have not required additional prednisolone during the first 48 weeks. To evaluate if methotrexate will be more efficient to control ENL than only prednisolone
