Evaluation of a pro-active strategy for managing tuberculosis-HIV co-infection in a UK tertiary care setting.

Management of tuberculosis (TB)-HIV co-infection is complicated by interactions between the diseases and their therapies. We developed and evaluated a strategy to (i) treat co-infected patients in a single co-infection clinic, (ii) maximize use of first-line drugs, (iii) delay antiretroviral therapy (ART) until two months post-TB treatment except in severe immunosuppression, (iv) commence efavirenz at 600 mg daily with therapeutic drug monitoring (TDM) and (v) target treatment completion. We conducted a prospective cohort review over 5.5 years in a UK tertiary referral center where 56 HIV-positive patients treated for TB were followed-up for a median 30 months. Main outcome measures were treatment completion, adverse events, immune reconstitution inflammatory syndrome, immunological and virological parameters, and TDM for efavirenz. Treatment completion rates were 88% (49/56); four patients were lost to local follow-up and three (5.4%) died during treatment; no deaths were TB-related. Adverse events were common (55%), but caused no treatment interruptions. Standard doses (600 mg daily) of efavirenz with rifampicin achieved or exceeded therapeutic levels in 25/28 (89%). This study supports combined management for TB-HIV co-infected patients. Delaying ART to two months post-TB treatment did not seem to result in poor clinical outcomes in this well-resourced context. Although efavirenz 600 mg daily usually achieved satisfactory levels, TDM is recommended.

Patient perception of cervical screening among women living with human immuno-deficiency virus infection attending an antiretroviral therapy clinic in urban South Africa.

This study aims to ascertain the perception of cervical screening practices among HIV-positive women attending an ART clinic in urban South Africa. It is a prospective cross-sectional study of 100 randomly selected patients using semi-structured interviews. Answers to fixed-response questions were recorded for statistical analysis and themes were identified from responses to open-ended questions. The study found that 59% of women surveyed reported ever having had a Papanicolau (Pap) smear and that 41% of these women had never been notified of the result. Many women surveyed lacked understanding of cervical screening; 78% had never heard of cervical cancer and around 40% had no correct knowledge about Pap smears. The findings suggest that cervical screening practices among HIV-positive women living in urban South Africa do not comply with the recommendations that are based on evidence of increased risk for this population. Systematic cervical screening programmes should be offered to HIV-positive women attending ART clinics in South Africa.
