Setting:
Queen Elizabeth Central Hospital, Blantyre, Malawi.Objectives:
To determine 1) the proportion of human immunodeficiency virus (HIV) infected tuberculosis (TB) patients started on antiretroviral therapy (ART), 2) the timing of ART and 3) the effect of the timing on TB treatment outcomes.Design:
A retrospective record review of HIV-infected TB patients registered from January to December 2009.Results:
A total of 3376 TB patients were registered, of whom 2665 (79%) were HIV-tested and 2042 (77%) were HIV-infected. A total of 1190 HIV-infected TB patients who were not on ART at the time of starting TB treatment were studied. Of 688 (58%) who started ART, 61% started therapy within 2 months of anti-tuberculosis treatment and 39% started later (≥2 months). Treatment success for patients with TB who started ART within 2 months was higher than for those starting ART later (RR 1.6, 95%CI 1.4–1.8), and death rates were lower (RR 0.25, 95%CI 0.19–0.35).Conclusion:
Under routine programme conditions in Malawi, a higher proportion of HIV-infected TB patients who started ART did so within 2 months of starting TB treatment, and early ART intervention was associated with better treatment outcomes. This confirms recommendations that co-infected TB patients should start ART early. 相似文献4.

A national survey was carried out in all the 103 public sector and 38 private sector facilities in Malawi providing antiretroviral therapy (ART) to determine uptake of ART and subsequent treatment outcomes in police force personnel. All patients registered for ART and their subsequent treatment outcomes were censored on December 31st 2006. There were 85168 patients started on ART in both public and private sectors, of whom 463 (0.6%) were police force personnel. Of police force personnel starting ART, 17% were in WHO clinical stage 1 or 2 with a CD4-lymphocyte count of ≤250 cells/µL and 83% were in stage 3 or 4. Treatment outcomes of police force personnel by the end of December 2006 were 302 (65%) alive and on ART at their registration facility, 59 (13%) dead, 30 (7%) lost to follow-up, 1 stopped treatment and 71 (15%) transferred to another facility. Their probability of being alive on ART at 6-, 12- and 18-months was 83.2%, 78.6% and 76.7% respectively. There has been a good access of police force personnel to ART since national scale up commenced with good treatment outcomes, and this should serve as an example for other police forces in the region. 相似文献

PURPOSE: Replication-selective oncolytic adenoviruses hold promise for cancer treatment, but the predictive use of cell lines, dissociated tumor tissue, and animal models for efficacy against primary cancers are unclear. To further evaluate cytotoxicity and the potential for efficacy of replication-competent adenoviruses we therefore developed a novel methodology using primary human cancer specimens ex vivo; ovarian, colon, rectal, and breast carcinomas were included. EXPERIMENTAL DESIGN: Tissue culture conditions were developed to maintain viability of adenocarcinomas ex vivo for 48 hours postsurgery. Explants were infected by replication-competent (wild type 5 and E1A mutant dl922-947) and replication-defective (dl312) adenoviruses; early (E1A) and late (hexon) viral gene expression, alphav integrins, coxsackievirus and adenovirus receptor (CAR) and tissue viability were assessed by immunohistochemistry and histopathology. Viral replication was verified by replication assays on selected samples. RESULTS: Viral gene expression varied dramatically among cancer specimens (n = 41). With Ad5, hexon expression was high in 8 of 11 tested specimens, whereas E1A levels were detectable in 16 of 27 tumor explants. Viral gene expression, distribution, and cytopathic effects were greater postinfection with dl922-947. Specimens that supported early gene expression (E1A) also supported viral replication in 13 of 14 tested cases, determined by recovery of infectious units. As predicted, the replication-defective adenovirus dl312 was not associated with viral gene expression. CONCLUSIONS: Primary human tumor tissue remained viable when cultured ex vivo enabling evaluation of viral mutants in tissue with intact morphology. This assay may have great use in determining treatment-sensitive cancers and assess specific oncolytic mutants in individual cases. 相似文献

Objective
To evaluate contraceptive adherence to the copper intrauterine device (Cu-IUD) and the injectable depot medroxyprogesterone acetate (DMPA) among women with HIV in Lilongwe, Malawi.Methods
We randomized 200 HIV-infected women on highly active antiretroviral therapy (HAART) to either the Cu-IUD or DMPA and followed these women prospectively, evaluating adherence and factors associated with nonadherence.Results
There was no difference in contraceptive adherence: 68% of Cu-IUD and 65% of DMPA users were adherent at 48 weeks. Receiving first-choice contraceptive was not associated with adherence. Women commonly cited partner's disapproval as an indication for discontinuation. Women who experienced heavy menstruation and first-time contraceptive users were more likely to be nonadherent. Among ongoing users at study conclusion, 95% were happy with their method, and 98% would recommend their method to a friend.Conclusion
Contraceptive adherence between the Cu-IUD and DMPA was similar at 1 year. With similar adherence and similar high rates of satisfaction among users of both methods at 1 year, the Cu-IUD offers a hormone-free alternative to DMPA.Implications
Adherence to the Cu-IUD and DMPA is similar at 1 year among HIV-infected women on HAART in a randomized controlled trial. Despite high method satisfaction, partner disapproval and heavy bleeding contribute to reduced adherence. Receiving a method that differs from participant's first-choice method did not influence adherence. 相似文献9.

Malawi’s Option B+ program provides all HIV-infected pregnant women free lifelong antiretroviral therapy (ART), but challenges remain regarding retention and ART adherence, potentially due to male partner barriers. We explored relationships between male partner involvement and Option B+ retention and adherence. In 2014, a randomized controlled trial in Malawi compared male recruitment strategies for couple HIV testing and counseling (cHTC) at an antenatal clinic. This secondary analysis was conducted among the entire cohort (N?=?200) of women, irrespective of randomization status. We assessed whether cHTC attendance, early disclosure of HIV-positive status, and partner ART reminders were associated with retention and adherence at one month after starting treatment. Retention was defined as attending HIV clinic follow-up within one day of running out of pills. Adherence was defined as taking ≥95% of ARTs by pill count. We used binomial regression to calculate adjusted risk ratios (aRR) and 95% confidence intervals (CI). Median female age was 26 years. Most women (79%) were retained; of these, 68% were adherent. Receiving cHTC was associated with improved retention (aRR 1.33, 95% CI 1.12, 1.59). Receiving male partner ART reminders was weakly associated with retention (aRR 1.16, 95% CI 0.96, 1.39). Disclosure within one day was not associated with retention (aRR 1.08, 95% CI: 0.91, 1.28). Among those who were retained, these three behaviors were not associated with improved 95% adherence. CHTC could play an important role in improving Option B+ retention. Increasing cHTC participation and enhancing adherence-related messages within cHTC are important. 相似文献
