In the largest Selleckchem Autophagy inhibitor of these, patients were randomly allocated to either CD4 cell count-guided intermittent therapy (stopping ART once CD4 cell count >350 cells/μL, restarting when CD4 cell count falls to 250 cells/μL) compared with a continuous ART [96]. The trial showed intermittent therapy was associated with a significantly higher rate of opportunistic disease and all-cause mortality and a higher rate of major cardiovascular, renal or hepatic disease. The effect was seen at all CD4 cell count levels. The study showed for the first time that continuous ART with virological suppression is associated with a reduction in the risk of non-AIDS co-morbidities and all-cause mortality as well

as HIV disease progression. For this reason, treatment interruption or intermittent therapy is not recommended. Once ART has been started in a patient with HIV infection, it should be continued. Temporary interruptions of 1–2 days can usually be managed and are unlikely to be associated with adverse outcomes. Longer interruptions of ART should only be considered in exceptional circumstances. These may include: After pregnancy, in women who have taken

ART during pregnancy to prevent mother-to-child transmission, but do not Ibrutinib cost otherwise require treatment. After early initiation of ART (CD4 cell counts >500 cells/μL) (e.g. when started to reduce infectiousness). Severe drug toxicity (e.g. hepatotoxicity). Severe psychological distress. Guidance on pharmacokinetic considerations when stopping ART is contained in Section 6.2.3 Stopping therapy: pharmacological considerations. “
“This study provides an estimate of the proportion

of HIV-positive patients in Italian clinics showing an ‘adverse prognosis’ (defined as a CD4 count ≤200 cells/μL or an HIV RNA >50 HIV-1 RNA copies/mL) over time, and investigates whether this proportion varied according to patients’ characteristics. We estimated the annual proportion of patients with a CD4 Glutamate dehydrogenase count ≤200 cells/μL or HIV RNA >50 copies/mL out of the total number of patients in the Icona Foundation cohort seen in any given year, both overall and after stratifying by demographical and treatment status groups. Generalized estimating equation models for Poisson regression were applied. In 1998–2008, the prevalence of patients with a CD4 count ≤200 cells/μL decreased from 14 to 6% [adjusted relative risk (RR) 0.86/year; 95% confidence interval (CI) 0.84–0.88; P<0.0001]. The prevalence of HIV RNA >50 copies/mL decreased from 66 to 40% (adjusted RR 0.95/year; 95% CI 0.95–0.96; P<0.0001) in all patients and from 38 to 12% in the subgroup of patients who had previously received antiretroviral therapy (ART) for ≥6 months (adjusted RR 0.89/year; 95% CI 0.88–0.90; P<0.0001). There was a substantial increase in the success rate of ART in Italy in 1998–2008, resulting in a lower percentage of patients with adverse prognosis in recent years.
