The data showed that deferring HAART until after TB treatment was completed was associated with a significant increase in mortality, even in patients with CD4 counts of >200 cells/μL, although there were few clinical events. We do not know if the six patients in this SAPIT study who died, out of the 86 who had TB, still had CD4 counts >200 cells/μL at the time of death. A recent study from Cambodia suggested that treatment with HAART Staurosporine in the first 2 weeks of TB treatment resulted in a lower mortality

rate than in the group delaying HAART to 8 weeks. The majority of these patients had a CD4 count of <100 cells/μL at enrolment [146]. The STRIDE (ACTG 5221) Study [147] also showed that starting HAART within 2 weeks resulted in http://www.selleckchem.com/products/MK-2206.html a lower mortality rate than in the group delaying HAART until 8–12 weeks in patients who had

a blood CD4 count of <50 cells/μL at enrolment [146]. In these trials the disadvantage of starting early was an increased risk of IRIS. Until we have further analyses of all data, we believe it is safer and more practicable to set a blood CD4 count of <100 cells/μL as the point below which HAART should be started within 2 weeks of commencing TB treatment. Other data sets suggest that starting HAART early, independent of CD4 cell count, improves long-term outcome [148,149]. Some physicians believe that starting HAART irrespective of CD4 cell count, including >350 cells/μL, is beneficial in patients with active TB. Although the SAPIT study suggested HAART started during the course of TB therapy, even in those with CD4 counts >350 cells/μL, was beneficial, almost all Edoxaban the patients within this arm had a CD4 count below that threshold. A study of the risks and benefits of starting HAART early vs. late in patients with HIV-associated TB meningitis in the developing world, where 90% of patients were male, the majority

were drug users, many had advanced disease and the diagnosis was made clinically in 40% of patients, showed no difference in mortality if HAART were started early, although there was a greater incidence of severe adverse events in the early arm [150]. How this translates to UK clinical practice remains unclear. Taking into account all the limited data available, we recommend: CD4 count (cells/μL) When to start HAART <100 As soon as practicable 100–350 As soon as practicable, but can wait until after completing 2 months of TB treatment, especially when there are difficulties with drug interactions, adherence and toxicities >350 At physician’s discretion After starting anti-tuberculosis treatment, some patients develop an exacerbation of symptoms, signs or radiological manifestations of TB. This has been well described in patients without HIV infection, but appears to occur more commonly in HIV-positive patients [151–169]. The phenomenon is known as IRIS, IRD or paradoxical reaction.
