Intimate partner violence (IPV) is a risk factor for non-adherence to HIV treatment for women, however the evidence on the impact of IPV on uptake of the prevention of mother to child transmission of HIV (PMTCT) cascade is inconclusive. We examined data from 433 HIV positive pregnant women in Kinshasa, Democratic Republic of Congo, enrolled between April 2013 and August 2014 and followed-up through 6 weeks postpartum. Participants were asked about their IPV experiences in a face-to-face interview at enrollment. Measures of PMTCT cascade included: uptake of clinical appointments and services, viral suppression, and adherence to antiretrovirals (ARV). Approximately half of the sample (51%) had experienced some form of IPV; 35% had experienced emotional abuse, 29% physical abuse, and 19% sexual abuse. There were no statistically significant associations between experiencing any form of IPV and uptake of clinical appointments and services (Adjusted Prevalence Ratio [aPR] = 1.02; 95% [CI]: 0.89–1.17), viral load suppression (aPR = 1.07, 95% CI:0.96–1.19) and ARV adherence (aPR = 1.01, 95% CI: 0.87–1.18). Findings from this study indicate that, among HIV-infected pregnant women enrolled in PMTCT care, experiencing IPV does not reduce adherence to clinic visits and services, adherence to ARV. The high prevalence of IPV in this population suggests that IPV screening and intervention should be included as part of standard care for PMTCT.
In 1988, 1233 prostitutes from different geographic areas of Kinshasa participated in a cross-sectional survey on HIV infection and other sexually transmitted diseases (STDs). Despite relatively good knowledge about AIDS and STDs, the reported preventive behaviour was poor. Only 12% of the women reported regular use of condoms, while >50% of the women reported regular use of antibiotics and 38% reported doing nothing specific to prevent STDs. Thirty-five per cent of the women were HIV-positive compared with 27% in a similar survey in Kinshasa in 1986. The prevalence of other STDs was very high, ranging from 5% for genital ulcer disease (GUD) to 23% for gonococcal infection. HIV-positive women were older than HIV-negative women (26.9 versus 25.4 years; P < 0.001), had a significantly lower level of reported condom use (9 versus 14%, P = 0.009), and reported more frequent use of antibiotics to prevent STDs (55 versus 42%, P = < 0.001). The prevalence of syphilis, gonorrhoea, chlamydial infection and trichomoniasis was not higher in HIV-positive women compared with HIV-negative women. However, HIV-positive women had a higher prevalence of GUD (9 versus 3%, P < 0.001), antibodies against Haemophilus ducreyi (82 versus 57%, P < 0.001), antibodies against herpes simplex virus type 2 (96 versus 76%, P < 0.001), condylomata accuminata (5 versus 1%, P = 0.003) and cytologic evidence of human papilloma virus on Papaniclaou cervical smear (11 versus 5%, P = 0.006). This study confirms the high incidence of HIV and other STDs among prostitutes in Africa. Taking into account the low frequency of effective preventive behaviour, these women are at high risk of acquiring and/or transmitting HIV. Targeted interventions aimed at increasing condom use and lowering STDs levels among this population are of the highest priority.
In Brief Background: Participants' protocol adherence may influence assessments of the effectiveness of new female-controlled methods for sexually transmitted infection prevention. Methods: In 2005 we conducted a randomized pilot study among female sex workers (FSWs) in Madagascar in preparation for sexually transmitted infection prevention trial of diaphragms and a vaginal microbicide. Participants (n = 192) were randomized into 4 arms: diaphragm plus microbicide (Acidform), diaphragm plus placebo gel hydroxyethyl cellulose (HEC), Acidform alone, or HEC alone. FSWs were seen weekly for 4 weeks. Using multivariable regression with generalized estimating equations, we assessed predictors of adherent product use during all sex acts in the last week. We collapsed the gel-diaphragm arms together and the gel-only arms together for this analysis. Results: Between 43% and 67% of gel-diaphragm users (varying by visit) reported using study products during all sex acts in the last week, compared with 20% to 45% of gel-only users. Adherence increased with follow-up [visit 4 vs. visit 1 risk ratio (RR) for gel-diaphragm users: 1.55, P <0.01; for gel-only users, RR: 1.58, P = 0.01]. Gel-diaphragm users whose casual partners were never aware of products (RR: 2.02, P = 0.03) and who had experienced partner violence after requesting condom use (RR: 1.45, P <0.01) were more adherent. Gel-only users reporting lower sexual frequency (1–9 weekly acts vs. ≥19 acts, RR: 1.98, P <0.01) and no sex with primary partners in the past week (RR: 1.54, P = 0.02) were more adherent. Conclusions: Gel-diaphragm users had better adherence than gel-only users, and predictors of adherence differed between groups. Addressing modifiable factors during counseling sessions may improve adherence. A 4-week randomized pilot trial of female sex workers in Madagascar assessed demographic, behavioral, product- and trial-related factors associated with adherent use of candidate vaginal microbicide and diaphragm during sex.
Women seeking care in Madagascar for genital discharge ( n =1066) were evaluated for syphilis seroreactivity; bacterial vaginosis (BV) and trichomoniasis. Chlamydial infection was assessed by ligase chain reaction (LCR) and by direct immunofluorescence (IF); gonorrhoea by direct microscopy, culture and LCR. Leucocytes were determined in endocervical smears and in urine using leucocyte esterase dipstick (LED). Gonococcal isolates were tested for minimal inhibitory concentrations. BV was found in 56%, trichomoniasis in 25%, and syphilis in 6% of the women. LCR detected gonorrhoea in 13% and chlamydial infection in 11% of the women. Detection of Gram(-) intracellular diplococci in endocervical smears, and gonococcal culture were respectively 23% and 57% sensitive and 98% and 100% specific compared to LCR. Chlamydia antigen detection by IF was 75% sensitive and 77% specific compared to LCR. Leucocytes in endocervical smears and LED testing lacked precision to detect gonococcal and chlamydial infections. Of 67 gonococcal strains evaluated, 19% were fully susceptible to penicillin, 33% to tetracycline; all were susceptible to ciprofloxacin, ceftriaxone, and spectinomycin. Patients who present with genital discharge in Madagascar should be treated syndromically for gonococcal and chlamydial infections and screened for syphilis. Gonorrhoea should be treated with ciprofloxacin.
Background: Based on clinical trial results, the World Health Organization recommends infant HIV testing at age 4–6 weeks and immediate antiretroviral therapy (ART) initiation in all HIV-infected infants. Little is known about the outcomes of HIV-infected infants diagnosed with HIV in the first weeks of life in resource-limited settings. We assessed ART initiation and mortality in the first year of life among infants diagnosed with HIV by 12 weeks of age. Methods: Cohort of HIV-infected infants in Kinshasa and Blantyre diagnosed before 12 weeks to estimate 12-month cumulative incidences of ART initiation and mortality, accounting for competing risks. Multivariate models were used to estimate associations between infant characteristics and timing of ART initiation. Results: One hundred and twenty-one infants were diagnosed at a median age of 7 weeks (interquartile range, 6–8). The cumulative incidence of ART initiation was 46% [95% confidence interval (CI), 36%, 55%] at 6 months and 70% (95% CI 60%, 78%) at 12 months. Only age at HIV diagnosis was associated with ART initiation by age 6 months, with a subdistribution hazard ratio of 0.70 (95% CI 0.52, 0.91) for each week increase in age at DNA polymerase chain reaction test. The 12-month cumulative incidence of mortality was 20% (95% CI 13%, 28%). Conclusions: Despite early diagnosis of HIV, ART initiation was slow and mortality remained high, underscoring the complexity in translating clinical trial findings and World Health Organization’s guidance into real-life practice. Novel and creative health system interventions will be required to ensure that all HIV-infected infants achieve optimal treatment outcomes under routine care settings.
The HIV seroprevalence per 100,000 adults Malagasy rose from 20 in 1989, to 30 in 1992, and to 70 in 1995. In that year, the total number of HIV infected people in the Big Island was estimated at 5,000, the number of people sick with AIDS at 130, and the people at risk at more than 1,000,000. The latter are the persons infected with other STDs and individuals (or their partners) with risky sexual behaviour (e.g. numerous sexual partners, occasional sexual partners, and/or sexual contacts with commercial sex workers). The HIV prevalence rate is low as compared with those of other countries. Nevertheless, the spread of the HIV infection is alarming in some parts of the country and the risk factors are also present, namely: the high prevalence of STDs, numerous sexual partners, the low use of condoms in all groups, the development of tourism, the development of prostitution associated with social and economical problems, and internal and international migrations (with risky sexual contacts). Therefore, the still low but rising HIV prevalence in 1995 does not warrant complacency. To estimate the trend of HIV prevalence within the population, it is useful to know two different assumptions, as follows: firstly, a controlled evolution of the epidemic (low epidemic) and secondly, a very fast spread of the epidemic (high epidemic). If we consider the 5,000 individuals seropositive in July 1995, the Aids Impact Model (AIM) projection model shows that HIV seroprevalence rates among adults in 2015 might be between 3% (when the progression course of HIV epidemic is low) and 15% (when the progression course of HIV epidemic is high). By 2015 AIDS could have severe demographic, social, and economic impacts. Then, it is necessary to take measures to prevent contamination. Five major interventions are required: public information about AIDS, HIV transmission mechanism, and its prevention, communities education via the respected people and the notabilities to promote moral values, reduce the number of sexual partners, delay visit of sexual activity, and advice for infected couples; screening of blood donors and the supposed high risk group; control of STDs; reduction of the number of sexual partners; promotion of condom use, abstinence, and fidelity. To sum up, the fight against AIDS is not only the health professional workers' problem. It concerns all Malagasy people. Therefore, successfullness in prevention efforts to slow the epidemic needs concerted, collective, and long lasting actions from all sectors of the society for the nation's future and the well-being of the rising generations.
Abstract Background HIV counseling and testing, HIV prevention and provision of HIV care and support are essential activities to reduce the burden of HIV among patients with TB, and should be integrated into routine TB care. Methods The development of training materials to promote HIV services for TB patients involved the definition of target health care workers (HCWs); identification of required tasks, skills and knowledge; review of international guidelines; and adaptation of existing training materials for voluntary counseling and testing, prevention of mother-to-child transmission of HIV, and management of opportunistic infections (OIs). Training effectiveness was assessed by means of questionnaires administered pre- and post-training, by correlating post-training results of HCWs with the centre's HIV testing acceptance rates, and through participatory observations at the time of on-site supervisory visits and monthly meetings. Results Pre-training assessment identified gaps in basic knowledge of HIV epidemiology, the link between TB and HIV, interpretation of CD4 counts, prevention and management of OIs, and occupational post-exposure prophylaxis (PEP). Opinions on patients' rights and confidentiality varied. Mean test results increased from 72% pre-training to 87% post-training (p < 0.001). Important issues regarding HIV epidemiology and PEP remained poorly understood post-training. Mean post-training scores of clinic's HCWs were significantly correlated with the centre's HIV testing acceptance rates (p = 0.01). On-site supervisory visits and monthly meetings promoted staff motivation, participatory problem solving and continuing education. Training was also used as an opportunity to improve patient-centred care and HCWs' communication skills. Conclusion Many HCWs did not possess the knowledge or skills necessary to integrate HIV activities into routine care for patients with TB. A participatory approach resulted in training materials that fulfilled local needs.
In the Discussion section of the article, “Vaginal microbicide and diaphragm use for sexually transmitted infection prevention: a randomized acceptability and feasibility study among high-risk women in Madagascar” (Sex Transm Dis 2008 Sep;35(9):818–26), we misstated key results of the MIRA study, which investigated the effect of a prevention package of the diaphragm, lubricant, and male condoms, compared to male condoms alone, for prevention of HIV and STI among Zimbabwean and South African women.1 We wrote: “Of note, self-reported condom use was similar for both arms at baseline, but during follow-up, significantly more women in the diaphragm arm than in the control arm reported condom use during the last sex act.” Actually, as is demonstrated by the figure in the Lancet publication that we cited, during the follow-up period participants’ reported condom use at last sex was lower in the intervention (diaphragm, lubricant and condom) arm compared to the control (condom only) arm.
OBJECTIVES--To compare characteristics of syphilis serological reactivity in HIV positive (+) and HIV negative (-) female sex workers, as well as the serological response to therapy after treatment with intramuscular benzathine penicillin, 2.4 million U weekly, for three consecutive weeks. METHODS--Rapid plasma reagin (RPR) and Treponema pallidum haemagglutination assay (TPHA) results of 72 HIV-positive and 121 HIV-negative women reactive in both tests were assessed. The response to therapy was prospectively monitored with quantitative RPR serology in 47 HIV-positive and 73 HIV-negative patients. Cumulative probabilities of becoming nonreactive by RPR were compared at six months, one and two years after therapy. RESULTS--At enrolment, the geometric mean titres of RPR and TPHA were lower in HIV-positive patients (RPR, 1:2.6) than in HIV-negative patients (RPR, 1:3.8; p < 0.01). The evolution over time of RPR titres was similar among HIV-positive patients as compared to HIV-negative patients. Among patients with an initial RPR titre of < 1:8, 53% of HIV-positive and 44% of HIV-negative patients became RPR negative two years after therapy. Among patients with an RPR titre of 1:8 or greater at enrolment, 83% of HIV-positive and 90% of HIV-negative patients had reached at least a fourfold decline of RPR titres two years after therapy. CONCLUSIONS--Syphilis serology findings (both RPR and TPHA) may be altered in the presence of HIV infection, but the serological response to therapy was similar in HIV-positive and HIV-negative patients.
To determine the accuracy and cost efficiency of pooling sera prior to HIV-1 testing, sera from 8,000 Kinshasa factory workers and their spouses were screened individually (2.44% seropositive) and in 800 pools of 10 sera each. There were no false-negative or false-positive pools, resulting in a calculated seroprevalence estimate of 2.42%. Further testing of all sera in positive pools can identify HIV-positive individuals. These applications were modeled to compare the cost-efficiency of pooling with individual testing under different conditions. The results suggest that pooling provides an alternative test format for use in both developing and industrialized countries when the seroprevalence and/or the marginal cost of obtaining a sample are sufficiently low. For our cohort, testing only the pools for seroprevalence estimation resulted in a 78% cost saving compared with individual testing; pooling with subsequent identification of individual seropositives represented a 56% cost reduction.
