Strategies to improve the uptake of Prevention of Mother-To-Child Transmission of HIV (PMTCT) are needed. We integrated HIV and maternal, newborn and child health services in a One Stop Clinic to improve the PMTCT cascade in a rural Tanzanian setting. The One Stop Clinic of Ifakara offers integral care to HIV-infected pregnant women and their families at one single place and time. All pregnant women and HIV-exposed infants attended during the first year of Option B+ implementation (04/2014-03/2015) were included. PMTCT was assessed at the antenatal clinic (ANC), HIV care and labour ward, and compared with the pre-B+ period. We also characterised HIV-infected pregnant women and evaluated the MTCT rate. 1,579 women attended the ANC. Seven (0.4%) were known to be HIV-infected. Of the remainder, 98.5% (1,548/1,572) were offered an HIV test, 94% (1,456/1,548) accepted and 38 (2.6%) tested HIV-positive. 51 were re-screened for HIV during late pregnancy and one had seroconverted. The HIV prevalence at the ANC was 3.1% (46/1,463). Of the 39 newly diagnosed women, 35 (90%) were linked to care. HIV test was offered to >98% of ANC clients during both the pre- and post-B+ periods. During the post-B+ period, test acceptance (94% versus 90.5%, p<0.0001) and linkage to care (90% versus 26%, p<0.0001) increased. Ten additional women diagnosed outside the ANC were linked to care. 82% (37/45) of these newly-enrolled women started antiretroviral treatment (ART). After a median time of 17 months, 27% (12/45) were lost to follow-up. 79 women under HIV care became pregnant and all received ART. After a median follow-up time of 19 months, 6% (5/79) had been lost. 5,727 women delivered at the hospital, 20% (1,155/5,727) had unknown HIV serostatus. Of these, 30% (345/1,155) were tested for HIV, and 18/345 (5.2%) were HIV-positive. Compared to the pre-B+ period more women were tested during labour (30% versus 2.4%, p<0.0001). During the study, the MTCT rate was 2.2%. The implementation of Option B+ through an integrated service delivery model resulted in universal HIV testing in the ANC, high rates of linkage to care, and MTCT below the elimination threshold. However, HIV testing in late pregnancy and labour, and retention during early ART need to be improved.

Background: To what extent antiretroviral therapy (ART) reduces mother-to-child HIV transmission (MTCT) during breastfeeding remains unclear. We assessed the MTCT risk from mothers on ART to their infants during breastfeeding.Setting: Ifakara, rural Tanzania.Methods: We included infants born between January 2013 and May 2016 to mothers who initiated ART before delivery, had a negative HIV DNA polymerase chain reaction at 4–12 weeks and exclusively breastfed for ≥6 months. Mothers' plasma HIV-RNA viral loads (VLs) were measured up to 11 months postdelivery. Infants were tested for HIV following national guidelines.Results: Among 214 women with 218 pregnancies and 228 infants (10 twins), the median age at delivery was 33 years (interquartile range 28–36 years), and the mean time on ART was 23 months (interquartile range, 4–52 months). VL was measured twice in 53% (113/218) of pregnancies. During breastfeeding, 91% of mothers (199/218) had VL of <1000 copies per milliliter, and 75% (164/218) had <100 copies per milliliter. To November 2017, 8% (19/228) of infants were lost to follow-up (LTFU), 2% (5/228) transferred, and 8% (18/228) died before the determination of final HIV serostatus. Among the remaining 186 infants, 2 (1%; 95% confidence interval: 0.3% to 4%) were HIV positive: 1 born from a mother with high VL 1-month postdelivery and 1 from a mother who interrupted ART. Assuming a 15% MTCT risk through breastfeeding among the 42 infants LTFU, transferred, or dead, the overall MTCT risk would be 4%.Conclusions: We found no MTCT from mothers who were retained in care and had suppressed VL. Breastfeeding signifies a very low risk when mothers adhere to ART. Adherence counseling, VL monitoring, and strategies to trace back those LTFU should be a priority.

Guidelines on prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) are inconsistently implemented in low-income countries. Strategies are needed to improve the uptake of these guidelines to prevent avoidable new HIV infections of infants. In 2010 the World Health Organisation presented its new PMTCT guidelines, offering two options for short courses of antiretroviral prophylaxis: Option A and Option B. Option A consists of antenatal prophylaxis with zidovudine followed by intrapartum and postpartum prophylaxis with single-dose nevirapine and zidovudine plus lamivudine. Option B recommends triple antiretroviral prophylaxis until after finishing breastfeeding. Tanzania has adopted Option A, and it is currently implementing it. A new option termed Option B+ has emerged recently, which recommends providing lifelong antiretroviral treatment to all HIV-positive pregnant women. In this article, we discuss the likely impact of this last PMTCT strategy in rural Africa with an example of an observational cross-sectional analysis in a rural referral hospital in Tanzania aiming to assess the uptake of PMTCT recommendations. Gaps were identified at all steps of the PMTCT pathway. Effective uptake of PMTCT guidelines has been shown to be extremely challenging in this setting. The continuously changing recommendations on PMTCT stress the need for a much simpler and effective approach. We argue in favour of implementing Option B+ in Tanzania. Financial challenges need to be faced, but Option B+ would help to overcome many barriers that prevent guidelines to be implemented in order to increase coverage and ultimately achieve the goal of ‘virtual elimination’ of mother-to-child transmission in sub-Saharan Africa.

Background: Strategies to improve HIV diagnosis and linkage into care, antiretroviral treatment coverage, and treatment outcomes of mothers and children are urgently needed in sub-Saharan Africa. Methods: From December 2012, we implemented an intervention package to improve prevention of mother-to-child transmission (PMTCT) and pediatric HIV care in our rural Tanzanian clinic, consisting of: (1) creation of a PMTCT and pediatric unit integrated within the reproductive and child health clinic; (2) implementation of electronic medical records; (3) provider-initiated HIV testing and counseling in the hospital wards; and (4) early infant diagnosis test performed locally. To assess the impact of this strategy, clinical characteristics and outcomes were compared between the period before (2008–2012) and during/after the implementation (2013–2014). Results: After the intervention, the number of mothers and children enrolled into care almost doubled. Compared with the pre-intervention period (2008–2012), in 2013–2014, children presented lower CD4% (16 vs. 16.8, P = 0.08) and more advanced disease (World Health Organization stage 3/4 72% vs. 35%, P < 0.001). The antiretroviral treatment coverage rose from 80% to 98% (P < 0.001), the lost-to-follow-up rate decreased from 20% to 11% (P = 0.002), and mortality ascertainment improved. During 2013–2014, 261 HIV-exposed infants were enrolled, and the early mother-to-child transmission rate among mother–infant pairs accessing PMTCT was 2%. Conclusions: This strategy resulted in an increased number of mothers and children diagnosed and linked into care, a higher detection of children with AIDS, universal treatment coverage, lower loss to follow-up, and an early mother-to-child transmission rate below the threshold of elimination. This study documents a feasible and scalable model for family-centered HIV care in sub-Saharan Africa.

Dalbavancin is an antibiotic active against most Gram-positive bacteria approved for acute bacterial skin and skin structure infections (ABSSSI). Owing to its long half-life, it is being increasingly used for other indications. We present a case series of children and adolescents treated with dalbavancin for osteoarticular, catheter-related and other non-ABSSSI infections. Dalbavancin was prescribed to 15 patients. Six (40%) were female and median age at prescription was 11.9 (IQR 1.3–18.0) years. Most of them (12/15) had significant comorbidities. Patients presented mainly with deep surgical site infections, osteoarticular infections and central-line-associated bloodstream infections. The most common isolate was Staphylococcus aureus followed by Staphylococcus epidermidis. Major reasons to prescribe dalbavancin were to ensure compliance and patients’ convenience. Two patients discontinued the drug due to adverse events possibly related to it. The rest of the patients completed the treatment with dalbavancin, with a median duration of 56 days (IQR 17.5, 115.5). All achieved complete resolution and present no relapse after a median follow-up of 9.9 months (IQR 4.8, 16.6). Dalbavancin was a safe, effective and convenient alternative in selected paediatric patients with complicated non-ABSSSI infections caused by Gram-positive bacteria.

The acquisition of drug-resistance mutations among African children living with in human immunodeficiency virus on antiretroviral treatment has been scarcely reported. This threatens the overall success of antiretroviral programs and the clinical outcomes of children in care. We present a well characterized series of children from rural Tanzania with acquired drug-resistance mutations to contribute to the better understanding of this emerging public health concern.
