NCT02281643

Brief Summary

This study will determine the influence of doxycycline treatment against Wolbachia/M. perstans on immunity against concomitant mycobacterial infections in healthy M. perstans infected individuals. In this regard, the investigators will perform a community-based randomized controlled trial (Phase 2a) in Asante Akim North District. A cohort of 200 participants who are contacts of patients with Tuberculosis or Buruli ulcer, of both sexes with no clinical condition requiring long-term medication but connected with Mansonella perstans will be investigated for the effect of doxycycline on microfilaria, the immune response and development of mycobacterial disease.

Outcome Measures

Primary Outcomes (1)

  • Microfilarial assessment

    Assessment of the microfilarial load

    Change from baseline microfilarial load at 12 months

Secondary Outcomes (1)

  • Demonstrate development of a T helper type 1 immunity through Immunological profile of cellular immune responses

    Change from baseline T helper type 1 cytokine levels at 24 weeks

Study Arms (2)

Early doxycycline administered

EXPERIMENTAL

Early doxycycline administered - volunteers will be treated immediately with 200mg daily doxycycline for 6 weeks

Drug: Doxycycline

Delayed doxycycline administered

ACTIVE COMPARATOR

Delayed doxycycline administered-volunteers will be treated six months after the early group has received treatment with 200mg daily doxycycline for 6 weeks

Drug: Doxycycline

Interventions

200mg oral doxycycline will be administered immediately (early) in the experimental arm or delayed in the comparator arm

Also known as: Vibramycim, Oracea
