Less Invasive Surfactant Administration: A Review of Current Evidence of Clinical Outcomes With Beractant.

Evidence supporting clinical recommendations or approval for less invasive surfactant administration (LISA) has primarily examined heterogeneous or small-volume (e.g., 1.25-2.5 mL/kg) animal-derived surfactant regimens. To address the evidence gap for larger-volume (e.g., 4-5 mL/kg) animal-derived surfactants, the aim of this review was to evaluate and summarize LISA literature for widely used larger-volume beractant. Surfactant treatment and the LISA technique were initially summarized. The available literature on beractant with LISA was thoroughly assessed and reviewed, including a recent systematic analysis, studies from regions where access or preferences may influence reliance on larger-volume surfactants, and investigations of short- and long-term outcomes. The available literature indicated improved short-term outcomes, including less need for mechanical ventilation, death, or bronchopulmonary dysplasia, and no negative long-term developmental outcomes when beractant was administered via LISA compared with older, more invasive techniques. The rates of short-term outcomes were similar to those previously observed in examinations of LISA with small-volume surfactants, including in populations reflecting very preterm infants. As uptake of LISA is expected to increase, future research directions for larger-volume surfactants include cost-effectiveness evaluations and robust examinations of repeat dosing and surfactant reflux to further inform clinical practice. This review provides a detailed assessment of the literature describing surfactant and LISA, with a focus on studies of beractant. Collectively, the available evidence supports the use of beractant with LISA based both on short-term and long-term outcomes relative to more invasive techniques and comparability of outcomes with small-volume surfactants and may be valuable in guiding clinical decision-making.

Beractant and poractant alfa in premature neonates with respiratory distress syndrome: a systematic review of real-world evidence studies and randomized controlled trials.

Findings from previous meta-analyses of randomized clinical trials (RCTs) in premature infants with respiratory distress syndrome (RDS) varied as to whether clinical outcomes differed by type of animal-derived pulmonary surfactant; real-world evidence (RWE) was excluded. We extracted study characteristics and outcomes from full-text articles from a systematic search for studies that compared beractant with poractant alfa for RDS in preterm infants. RWE data were tabulated; RCT data were subjected to meta-analyses. Designs, patient characteristics, and follow-up durations varied widely among studies (4 RWE, 15 RCT). RWE studies with adjusted odds ratios (ORs) found no statistically significant between-treatment differences in outcomes. In RCT meta-analyses, no statistically significant between-treatment differences were observed for death (OR [95% confidence interval], 1.35 [0.98-1.86]), bronchopulmonary dysplasia (1.25 [0.96-1.62]), pneumothorax (1.21 [0.72-2.05]), and air leak syndrome (2.28 [0.82-6.39]). Collectively, outcomes were similar with beractant and poractant alfa in RWE studies and pooled RCTs.

The Association Between HIV Disclosure Status and Perceived Barriers to Care Faced by Women Living with HIV in Latin America, China, Central/Eastern Europe, and Western Europe/Canada.

Generally, women are less likely than men to disclose their HIV status. This analysis examined the relationship between HIV disclosure and (1) perceived barriers to care and (2) quality of life (QoL) for women with HIV. The ELLA (EpidemioLogical study to investigate the popuLation and disease characteristics, barriers to care, and quAlity of life for women living with HIV) study enrolled HIV-positive women aged ≥18 years. Women completed the 12-item Barriers to Care Scale (BACS) questionnaire. QoL was assessed using the Health Status Assessment. BACS and QoL were stratified by dichotomized HIV disclosure status (to anyone outside the healthcare system). Multilevel logistic regression analysis was used to identify factors associated with disclosure. Of 1945 patients enrolled from Latin America, China, Central/Eastern Europe, and Western Europe/Canada between July 2012 and September 2013, 1929 were included in the analysis (disclosed, n = 1724; nondisclosed, n = 205). Overall, 55% of patients lived with a husband/partner, 53% were employed, and 88% were receiving antiretroviral therapy. Patients who were with a serodiscordant partner were more likely to disclose (p = 0.0003). China had a disproportionately higher percentage of participants who did not disclose at all (nearly 30% vs. <15% for other regions). Mean BACS severity scores for medical/psychological service barriers and most personal resource barriers were significantly lower for the disclosed group compared with the nondisclosed group (p ≤ 0.02 for all). Compared with the disclosed group, the nondisclosed group reported statistically significantly higher (p ≤ 0.03) BACS item severity scores for 8 of the 12 potential barriers to care. The disclosed group reported better QoL. Overall, HIV nondisclosure was associated with more severe barriers to accessing healthcare by women with HIV.

Outcomes related to 4864 pregnancies with exposure to lopinavir/ritonavir (LPV/r).

INTRODUCTION: During pregnancy, LPV/r is a common anchor drug employed to treat the mother's HIV-1 infection in addition to reducing the risk of mother-to-child transmission (MTCT). The National Study of HIV in Pregnancy and Childhood (NSHPC) conducts a comprehensive population-based surveillance of HIV infection in pregnant women exposed to antiretroviral therapy (ART) in the UK and Ireland; in 2003-2012 over a third of pregnancies reported to the NSHPC involved exposure to LPV/r. METHODS: We undertook a retrospective were descriptive analysis of individual NSHPC patient data, using pregnancy as the unit of observation. Clinical outcomes for pregnancies reported by June 2013, where women were exposed to LPV/r and due to deliver between January 2003 and December 2012, are described. RESULTS: A total of 4864 LPV/r exposed pregnancies in 4118 women were identified. These resulted in 4702 deliveries with 4759 live and 46 stillborn infants. Seventy five percent of women were born in sub-Saharan Africa, 13% in the UK or Ireland. Median maternal age at conception was 30 years. Nine hundred and eighty (20%) pregnancies were conceived while taking LPV/r, with a median duration of LPV/r exposure of 270 days. A total of 3884 (80%) pregnancies initiated LPV/r after conception, with a median duration of LPV/r exposure of 107 days. Viral load (VL) close to delivery was available for 4083/4702 (87%) deliveries, with VL <50 c/mL in 73% and <1000 c/mL in 94% of women. VL by timing of LPV/r initiation is shown in Table 1. Sixty three percent of deliveries were by C-section, of which 62% were classified as elective and 38% as emergency. Among singleton liveborn infants, 13% were born prior to 37 weeks gestation (2.5% <32 weeks) and 15% had birth weight <2500 g (2.3% <1500 g). HIV infection status was available for 4039 (89%) singleton infants. For the periods 2003-2007 and 2008-2012, MTCT rates were 1.1% (95% CI 0.6-1.6) and 0.5% (95% CI 0.2-0.8) respectively. Hundred and thirty four live born children (2.8%) had at least one congenital abnormality reported. CONCLUSIONS: In the NSHPC database, in women exposed to LPV/r during pregnancy in the UK and Ireland, MTCT rates are low and continue to decline, and are similar to rates in the entire NSHPC cohort of women with diagnosed HIV [1]. The congenital abnormality rate is comparable with that reported for the uninfected population in this geographic region.
