Acceptability of voluntary HIV testing by pregnant women in developing countries: an international survey. Ghent International Working Group on Mother-to-Child Transmission of HIV.

International audienceOBJECTIVE: To evaluate acceptability of voluntary HIV counselling and testing (VCT) by pregnant women in the context of clinical trials assessing interventions to reduce mother-to-child transmission (MCT) of HIV in developing countries. METHODS: During September-October 1997, 13 studies located in West (Abidjan, Bobo Dioulasso), East (Nairobi, Mombasa, Dar Es Salaam, Blantyre, Lusaka, Harare) and South Africa (Soweto, Durban), and Thailand (Bangkok) were included in a cross-sectional mailing survey about the acceptability of VCT in antenatal clinics. Acceptance rate, return rate, overall acceptability of VCT (acceptance of both pre- and post-VCT sessions) were obtained using a standardized questionnaire. RESULTS: The median overall acceptability of VCT was 69% (range, 33-95%). Overall acceptability of VCT most frequently depended on return rates because acceptance rates were generally high. Where several studies were conducted in parallel in the same city or the same country, overall acceptability rates of HIV testing were generally comparable even if the intervention programmes differed. Overall acceptability rates of VCT were high in antenatal clinics where a particular effort in implementing VCT programmes had been made. CONCLUSIONS: This international survey shows that despite many obstacles, VCT is feasible and acceptable for pregnant women aiming to reduce their risk of transmitting HIV to their children

Histological features of peripilar signs associated with androgenetic alopecia

A study of the scalp in a large cohort of volunteers with androgenetic alopecia using macrophotographs showed the presence of peripilar signs (PPS) around the hair ostia.The aim of the present study was to establish the histopathological features related to PPS.Prospective clinicopathological study.Department of Dermatology, University Hospital of Bologna.A group of 40 patients (21 males and 19 females) participated in the study. Macrophotographs of the scalp were taken using a Dermaphot camera and PPS were scored using a three-point scale. Hair density and PPS were clinically scored according to reference scales. Two punch biopsies from the photographed area were obtained from each subject and histological analysis was performed on vertical and horizontal sections.Clinical parameters indicated that PPS were already detectable on scalp with high hair density. Moreover, in patients with high hair density (score >4), a significant relationship was found between the PPS score and the global score for perifollicular infiltrates. Thus PPS are linked to superficial perifollicular lymphocytic infiltrates in early androgenetic alopecia.PPS could be the clinical signs reflecting the presence of perifollicular infiltrates

Morbidity in relation to feeding mode in African HIV-exposed, uninfected infants during the first 6 mo of life: The Kesho Bora study

Background: refraining from breastfeeding to prevent HIV transmission has been associated with increased morbidity and mortality in HIV-exposed African infants.Objective: the objective was to assess risks of common and serious infectious morbidity by feeding mode in HIV-exposed, uninfected infants ?6 mo of age with special attention to the issue of reverse causality.Design: HIV-infected pregnant women from 5 sites in Burkina Faso, Kenya, and South Africa were enrolled in the prevention of mother-to-child transmission Kesho Bora trial and counseled to either breastfeed exclusively and cease by 6 mo postpartum or formula feed exclusively. Maternal-reported morbidity (fever, diarrhea, and vomiting) and serious infectious events (SIEs) (gastroenteritis and lower respiratory tract infections) were investigated for 751 infants for 2 age periods (0–2.9 and 3–6 mo) by using generalized linear mixed models with breastfeeding as a time-dependent variable and adjustment for study site, maternal education, economic level, and cotrimoxazole prophylaxis.Results: reported morbidity was not significantly higher in nonbreastfed compared with breastfed infants [OR: 1.31 (95% CI: 0.97, 1.75) and 1.21 (0.90, 1.62) at 0–2.9 and 3–6 mo of age, respectively]. Between 0 and 2.9 mo of age, never-breastfed infants had increased risks of morbidity compared with those of infants who were exclusively breastfed (OR: 1.49; 95% CI: 1.01, 2.2; P = 0.042). The adjusted excess risk of SIEs in nonbreastfed infants was large between 0 and 2.9 mo (OR: 6.0; 95% CI: 2.2, 16.4; P = 0.001). Between 3 and 6 mo, the OR for SIEs was sensitive to the timing of breastfeeding status, i.e., 4.3 (95% CI: 1.2, 15.3; P = 0.02) when defined at end of monthly intervals and 2.0 (95% CI: 0.8, 5.0; P = 0.13) when defined at the beginning of intervals. Of 52 SIEs, 3 mothers reported changes in feeding mode during the SIE although none of the mothers ceased breastfeeding completely.Conclusions: not breastfeeding was associated with increased risk of serious infections especially between 0 and 2.9 mo of age. The randomized controlled trial component of the Kesho Bora study was registered at Current Controlled Trials (www.controlled-trials.com) as ISRCTN7146840

Early infant feeding patterns and HIV-free survival

Objective: to investigate the association between feeding patterns and HIV-free survival in children born to HIV-infected mothers and to clarify whether antiretroviral (ARV) prophylaxis modifies the association.Methods: from June 2005 to August 2008, HIV-infected pregnant women were counseled regarding infant feeding options, and randomly assigned to triple-ARV prophylaxis (triple ARV) until breastfeeding cessation (BFC) before age 6 months or antenatal zidovudine with single-dose nevirapine (short-course ARV). Eighteen-month HIV-free survival of infants HIV-negative at 2 weeks of age was assessed by feeding patterns (replacement feeding from birth, BFC <3 months, BFC ?3 months).Results: of the 753 infants alive and HIV-negative at 2 weeks, 28 acquired infection and 47 died by 18 months. Overall HIV-free survival at 18 months was 0.91 [95% confidence interval (CI): 0.88–0.93]. In the short-course ARV arm, HIV-free survival (0.88; CI: 0.84–0.91) did not differ by feeding patterns. In the triple ARV arm, overall HIV-free survival was 0.93 (CI: 0.90–0.95) and BFC <3 months was associated with lower HIV-free survival than BFC ?3 months (adjusted hazard ratio: 0.36; CI: 0.15–0.83) and replacement feeding (adjusted hazard ratio: 0.20; CI: 0.04–0.94). In the triple ARV arm, 4 of 9 transmissions occurred after reported BFC (and 5 of 19 in the short-course arm), indicating that some women continued breastfeeding after interruption of ARV prophylaxis.Conclusions: in resource-constrained settings, early weaning has previously been associated with higher infant mortality. We show that, even with maternal triple-ARV prophylaxis during breastfeeding, early weaning remains associated with lower HIV-free survival, driven in particular by increased mortalit
