Survival of HIV patients with tuberculosis started on simultaneous or deferred HAART in the THRio cohort, Rio de Janeiro, Brazil

Background: The timing of highly active antiretroviral therapy (HAART) after a tuberculosis diagnosis in HIV-infected patients can affect clinical outcomes and survival. We compared survival after tuberculosis diagnosis in HIV-infected adults who initiated HAART and tuberculosis therapy simultaneously to those who delayed the start of HAART for at least two months. Methods: The THRio cohort includes 17,983 patients receiving HIV care in 29 public clinics in Rio de Janeiro, Brazil. HAART-naïve patients at the time of a new TB diagnosis between September 2003 and June 2008 were included. Survival was measured in days from diagnosis of TB. We compared survival among patients who initiated HAART within 60 days of TB treatment (simultaneous – ST) to those who started HAART >60 days of TB treatment or never started (deferred – DT). Kaplan–Meier plots and Cox proportional hazards regression analyses were conducted. Results: Of 947 patients diagnosed with TB, 572 (60%) were HAART naïve at the time of TB diagnosis; 135 were excluded because of missing CD4 count results. Among the remaining 437 TB patients, 56 (13%) died during follow-up: 25 (10%) among ST patients and 31 (16%) in DT group (p = 0.08). ST patients had lower median CD4 counts at TB diagnosis than DT patients (106 vs. 278, p < 0.001). Cox proportional hazards utilizing propensity score analysis showed that DT patients were more likely to die (adjusted HR = 1.89; 95% CI: 1.05–3.40; p = 0.03). Conclusion: HAART administered simultaneously with TB therapy was associated with improved survival after TB diagnosis. HAART should be given to patients with HIV-related TB as soon as clinically feasible. .

Risk Factors and Case Management of Acute Diarrhoea in North Gondar Zone, Ethiopia.

In Ethiopia, evidence is lacking about maternal care-taking and environmental risk factors that contribute to acute diarrhoea and the case management of diarrhoea. The aim of this study was to identify the risk factors and to understand the management of acute diarrhoea. A pretested structured questionnaire was used for interviewing mothers of 440 children in a prospective, matched, case-control study at the University of Gondar Referral and Teaching Hospital in Gondar, Ethiopia. Results of multivariate analysis demonstrated that children who were breastfed and not completely weaned and mothers who were farmers were protective factors; risk factors for diarrhoea included sharing drinking-water and introducing supplemental foods. Children presented with acute diarrhoea for 3.9 days with 4.3 stools per day. Mothers usually did not increase breastmilk and other fluids during diarrhoea episodes and generally did not take children with diarrhoea to traditional healers. Incorporating messages about the prevention and treatment of acute diarrhoea into child-health interventions will help reduce morbidity and mortality associated with this disease.

Prevalence and risk factors for reproductive tract infections among women in rural Vietnam.

The objective of this study was to estimate prevalence and risk factors of reproductive tract infections (RTIs) among women in Haiphong, Vietnam. In October 1998, 197 women aged 18-49 were recruited into a community-based, cross-sectional study. Of the 197 women, 95 (49.5%) were diagnosed with > or = 1 endogenous reproductive tract infections (RTI) and 7 (3.6%) with > or = 1 sexually transmitted disease (STD). In three separate multivariate analyses, age <30 years (OR = 2.5; 95% CI = 1.1, 5.8), residential mobility (OR = 2.3; 95% CI = 1.1, 4.9), self reported genital itch/discharge (OR = 2.1; 95% CI = 1.1, 4.1), and reported belief that RTI symptoms were shameful (OR = 2.5; 95% CI = 1.2, 5.0) were associated with bacterial vaginosis (BV); low education was associated with candida (OR = 2.6; 95% CI = 1.0, 6.7); > or = 1 abortion was associated with > or = 1 STD (OR = 9.2; 95% CI = 1.1, 427). The prevalence of STDs was low but the prevalence of endogenous infections was high. Abortion is a proxy for other factors, such as high risk sexual behavior in either the woman or her partner. Given the low prevalence STD in this area of Vietnam, clinical case management of women presenting with RTI symptoms should focus on treatment of the more common endogenous infections, candida and BV.
