Overview

Several West African countries are badly affected by Buruli ulcer, an unsightly skin condition caused by infection with Mycobacterium ulcerans. Buruli ulcer affects predominantly the upper and lower limbs of patients and common in rural tropical communities in West and Central Africa. In Ghana it is one of the commonest skin NTDs.

The Buruli ulcer group is particularly interested in promoting approaches aimed at early detection of the disease, understanding the mechanisms underlying disease pathogenesis, improving diagnostic confirmation and optimization of antibiotic treatment and its outcomes.

The group currently collaborates extensively with local partners and international partners from all over the world including Africa, United Kingdom, USA, Europe in carrying out research aimed at improving the care of Buruli ulcer patients globally. Our activities include training, planning, supervision, implementation of clinical and epidemiological studies.

Research Projects

Ongoing Research projects:

The role of coagulation in the pathogenesis of Buruli ulcer

The necrotic subcutaneous tissue of the Buruli lesions can be extensive. Wound healing is a major issue in Buruli ulcer and healing rates can range widely between patients, although it is not clear why. Haemostatic components including thrombomodulin have known roles in wound healing, therefore this research will throw light onto these under-explored areas. This is a collaborative study with the University of Surrey (UK) and sponsored by a Wellcome Trust grant to Dr Rachel Simmonds. The overarching hypothesis is that disordered haemostasis in the skin tissue of BU patients initiates lesion formation and determines clinical susceptibility.  Here we at explore that role of haemostasis (blood clotting) in the pathogenesis of Buruli ulcer.

This study will substantially increase our understanding of the pathogenic mechanism of Buruli ulcer lesion development. It will show whether it might be possible to improve BU treatment strategies by harnessing anticoagulants alongside antibiotics to reduce healing times. It will contribute to knowledge of the interaction between coagulation and infectious diseases more widely.

Pathogenesis and management of M. ulcerans disease, Buruli ulcer  

This study sponsored by the MRC/DFID African Research Leader scheme aims to identify markers of rapid response to antibiotic treatment in Mycobacterium ulcerans disease and to investigate the pathogenesis of oedematous disease and paradoxical reactions in M. ulcerans disease. Methods include molecular, mass spectrometry and immunological approaches using flow cytometry. Proteome biomarkers are validated for field applicability.

Using a novel a novel molecular assay we already show that patients with detectable viable organisms after antibiotic treatment had significantly higher bacterial load at baseline, longer healing time and lower healing rate at week 4 compared with those with undetectable viable organisms at baseline or by week 4.

Results suggest that although current antibiotic therapy for BU disease is highly successful in most patients it may be possible to abbreviate treatment to 4 weeks in patients with a low initial bacterial load. On the other hand persistent infection contributes to slow healing in patients with a high bacterial load, some of whom may need antibiotics for longer than 8 weeks. 1 PhD students and 4 MSc students have been trained on this project

 

Co-infection of M. tuberculosis or M ulcerans with Mansonella perstans in Ghana and Cameroun

The DFG provided sponsorship for our group and partners in the University of Bonn and Duesseldorf ( Germany) and University of Buea (Cameroon) to better understand the effect of Mansonella perstans co-infection on mycobacterial diseases such as Buruli ulcer and Tuberculosis.

M. perstans is one of the most prevalent human parasites in sub-Saharan Africa. However the epidemiology of M. perstans in most regions and relevant transmitting vector species are poorly defined. We were able to characterize ecological zones prerequisite for M. perstans infection and identified a potential novel vector for transmission of M. perstans in the initial project period. Amongst others we demonstrated that M. perstans infections are strongly linked to dense equatorial rainforest areas and mass drug administration with the anti-helminthic drug ivermectin had limited efficacy on M. perstans prevalence in areas with optimal vector habitat (Wanji el al. Parasit Vectors, 2016). In addition, we could show that Culicoides (C.) milnei is the transmitting vector for M. perstans in South-West region within Cameroon

Mansonella perstans (M. perstans) epidemiology, the role of Wolbachia endosymbionts and M. perstans infection effects on host immunity. In addition we characterized immunological mechanisms crucial for protection as well as pathognomonic features of mycobacterial diseases (i.e. Buruli disease and tuberculosis). Outstanding progress has been made in several topics and great collaborations have been established between the partner institutes from Ghana, Cameroon, and Germany. These achievements enable us now to target challenging efficacy trials on the role of M. perstans for M. bovis BCG vaccine induced protection as well as tuberculosis disease manifestation and recovery in Ghana and Cameroon.

Recently completed projects:

Training and field evaluation of new diagnostic tool for Buruli ulcer in Ghana

The goal of this work is to establish fluorescent thin layer chromatography in endemic sites and to train laboratory technicians from 6 Buruli ulcer endemic districts in Ghana on a standard protocol for this new diagnostic tool for Buruli ulcer disease and in its field evaluation.
