Clinical features and management of a severe paradoxical reaction associated with combined treatment of Buruli ulcer and HIV co-infectionIn West and Central Africa Buruli ulcer (BU) and HIV co-infection is increasingly recognised and management of these two diseases combined is an emerging challenge for which there is little published information. In this case we present a severe paradoxical reaction occurring after commencing antibiotic treatment for BU combined with antiretroviral therapy for HIV, and describe its clinical features and management. This includes to our knowledge the first reported use of prednisolone in Africa to manage a severe paradoxical reaction related to BU treatment.
Impact of HIV on the Severity of Buruli Ulcer Disease: Results of a Retrospective Study in CameroonBackground: Buruli ulcer (BU) is the third most common mycobacterial disease after tuberculosis and leprosy and is particularly frequent in rural West and Central Africa. However, the impact of HIV infection on BU severity and prevalence remains unclear. Methods: This was a retrospective study of data collected at the Akonolinga district hospital, Cameroon, from 1 January 2002 to 27 March 2013. HIV prevalence among BU patients was compared to regional HIV prevalence. Baseline characteristics of BU patients were compared between HIV-negative and HIV-positive patients, and according to CD4 cell count strata in the latter group. BU time-to-healing was assessed in different CD4 count strata and factors associated with BU main lesion size at baseline were identified. Results: HIV prevalence among BU patients was significantly higher than the regional estimated prevalence in each group (children, 4.00% vs 0.68% [P < .001]; men, 17.0% vs 4.7% [P < .001]; women, 36.0% vs 8.0% [P < .001]). HIV-positive individuals had a more severe form of BU with an increased severity in those with a higher level of immunosuppression. Low CD4 cell count was significantly associated with a larger main lesion size (beta-coefficient, -0.50; P = .015; 95% confidence interval [CI], -0.91 – 0.10). BU time-to-healing was more than double in patients with a CD4 cell count below 500 cell/mm3 (hazard ratio, 2.39; P = .001, 95% CI, 1.44 - 3.98). Conclusion: HIV-positive patients are at higher risk for BU. HIV-induced immunosuppression appears to have an impact on BU clinical presentation and disease evolution.
Management of BU-HIV co-infectionBuruli Ulcer (BU)-HIV co-infection is an important emerging management challenge for BU disease. Limited by paucity of scientific studies, guidance for management of this co-infection has been lacking.
