Treatment of Pediculosis (Head Lice) in Senegal

This is a prospective single-arm interventional study evaluating Therapeutic efficacy of a combination of two pharmaceutical drugs, Azithromycin (AZIT) and Ivermectin (IVER) administered orally in the treatment of head lice infestations. In case of persistence of lice and / or nits on day 7, a second oral administration of combination Azithromycin + Ivermectin will be considered.

The duration of the study period is 4 months, ie 1 month and ½ of inclusion and 2 months and ½ feedback. There will be a site initiation visit "site initiation visit" before inclusions at D-7, two monitoring visits and a closing visit "close out visit" at the end of the follow-up at 4 months.

The investigators will perform a clinical trial of efficacy, single-arm, until D28 from volunteer subjects infested with head lice.

The two villages of the study (Dielmo and Ndiop) will be visited to explain the protocol and obtain community permission to work on it. Schools will also be visited to inform teachers and explain the protocol. The search for lice will be done by village women recruited for this purpose. A systematic census by family will be performed. A clinical examination of the hair will detect the persons infested with lice. On D-1, individual informed consent (an assent for participants between the ages of 15 and 18) will be systematically obtained before inclusion.

At D1, an interview and a complete clinical examination will be done on each subject consenting. All volunteers meeting the inclusion criteria will be taken on a single arms. For each voluntary participant selected fasting 1 hour before, the treatments will be administered by the investigators of the study. After taking the AZIT + IVER dose, each treated volunteer will be followed for 1 hour to observe the appearance of any side effects, then a breakfast will be offered. Head lice and nits will be searched on D1, D7, D15 and D28 for each volunteer and the hair taken on D2, D5, D7, D15 and D28. Possibly, before each treatment, Stool samples will be taken systematically on day 1 and after treatment on day 15 at any participant infested with head lice to identify intestinal parasites (load parasite in helminthiasis) to evaluate also the efficacy of ivermectin on these parasites. Sociodemographic, clinical, dose and type of material taken biological will be documented. Data on co-infections (body lice, Sarcoptes scabeii) will also be collected and reported on the study register. Each volunteer will have an identification number (ID). Only, the principal investigator, the coordinator and the investigators can access sensitive information if they exist. Data will be entered immediately by a data entry agent. The investigators will sleep on the sites and will face possible cases of effects undesirable. Regular visits will be scheduled on D2, D5, D7, D15 and D28. A clinical monitor will stay with the team on the field of D2, D5, D7, D15 and D28. A Clinical Research Organisation (CRO) will ensure the external monitoring of the study (1 site initiation visit, 2 monitoring visits and 1 visit closing of the test). It will also be scheduled for a visit by Comité National d'Ethique en Santé (CNERS) members on the field according to their schedule. All willing participants and completing the eligibility criteria for entry into this study, will be taken on a single treatment arm Azithromycin-Ivermectin in orodispersible tablets. The evaluation of the answer therapy will be done on D7 and / or D15.
