在非洲丛林地区,1700万盘尾丝虫感染者中有50％以上的患者主要表现为盘尾丝虫性皮肤病(OSD),这已成为当地一个重要公共卫生问题。严重的瘙痒症是感染者最重要的并发症。本研究使用伊维菌素每隔3个月、6个月和1年服用1次,连续15个月,采用双盲法,设安慰剂对照组,追踪观察伊维菌素对盘尾丝虫性皮肤病和严重瘙痒症的疗效。 In the African jungle region, over 50% of the 17 million people infected with Onchocerciasis are predominantly Onchocerciasis (OSD), an important public health problem in the area. Severe pruritus is the most important complication of infection. This study used ivermectin once every 3 months, 6 months and 1 year for 15 consecutive months. The double-blind, placebo-controlled group was followed up with ivermectin against Onchocerciasis Dermatosis and severe pruritus.
