Multidrug-resistant tuberculosis (MDR-TB) outcomes are poor partly because of the long treatment duration; the World Health Organization conditionally recommends a shorter course regimen to potentially improve treatment outcomes. Here, we describe the drug susceptibility patterns of a cohort of MDR-TB patients in Haiti and determine the number of likely effective drugs if they were treated with the recommended shorter course regimen. We retrospectively examined drug susceptibility patterns of adults initiating MDR-TB treatment between 2008 and 2015 at the Haitian Group for the Study of Kaposi's Sarcoma and Opportunistic Infections in Port-au-Prince, Haiti. First- and second-line drug susceptibility testing (DST) was analyzed and used to determine the number of presumed effective drugs. Of the 239 patients analyzed, 226 (95%), 183 (77%), 135 (57%), and 38 (16%) isolates were resistant to high-dose isoniazid, ethambutol, pyrazinamide, and ethionamide, respectively. Eight patients (3%) had resistance to either a fluoroquinolone or a second-line injectable and none had extensively resistant TB. Of the 239 patients, 132 (55%) would have fewer than five likely effective drugs in the intensive phase of the recommended shorter course regimen and 121 (51%) would have two or fewer likely effective drugs in the continuation phase. Because of the high rates of resistance to first-line TB medications, about 50% of MDR-TB patients would be left with only two effective drugs in the continuation phase of the recommended shorter course regimen, raising concerns about the effectiveness of this regimen in Haiti and the importance of using DST to guide treatment.

Background Attrition during the period from HIV testing to antiretroviral therapy (ART) initiation is high worldwide. We assessed whether same-day HIV testing and ART initiation improves retention and virologic suppression. Methods and findings We conducted an unblinded, randomized trial of standard ART initiation versus same-day HIV testing and ART initiation among eligible adults [greater than or equal to]18 years old with World Health Organization Stage 1 or 2 disease and CD4 count [less than or equal to]500 cells/mm.sup.3 . The study was conducted among outpatients at the Haitian Group for the Study of Kaposi's Sarcoma and Opportunistic infections (GHESKIO) Clinic in Port-au-Prince, Haiti. Participants were randomly assigned (1:1) to standard ART initiation or same-day HIV testing and ART initiation. The standard group initiated ART 3 weeks after HIV testing, and the same-day group initiated ART on the day of testing. The primary study endpoint was retention in care 12 months after HIV testing with HIV-1 RNA Conclusions Same-day HIV testing and ART initiation is feasible and beneficial in this setting, as it improves retention in care with virologic suppression among patients with early clinical HIV disease.
