Description of intervention(s) / exposure
Ivermectin is a semisynthetic product from Streptomyces avermitilis.

The compound has activity against internal and external parasites as arthropods, insects, filaroidea, platyhelmints and protozoa. The usual dosage for human use is 150 or 200 micrograms/kg as an unique dose, per orum.

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be examined by hemoscopy (venopuncture) for the presence of Mansonella ozzardi in their blood. These subjects are riverine inhabitants of Purus River in the municipality of Labrea, Amazonas State, an area of high prevalence of mansoneliasis. Those who agree will be enrolled in the study , will be treated with ivermectine 150 mcg/kg (as already used for the treatment of with Onchocerca volvulus infections ) in an unique dose and followed-up for 180 days

Summary
Brief summary
Mansonella ozzardi infection is highly prevalent in the Amazonian riverine population in Brazil. The Brazilian government has no drug protocol for the treatment of such disease. In order to determine the efficacy and safety of the use of ivermectine in the treatment of such disease, 50 subjects between 5-60 years old will be enrolled and treated with ivermectine 150 mcg/kg (the usual dosage for the treatment of Onchocerca volvulus infections) in an unique dose and followed-up for 180 days in order to observe microfilaremia clearance and the occurence of side-effects post ivermectin treatment
