[PMID: 38953228 DOI: 10.1111/jpc.16609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 06/06/2024] [Accepted: 06/20/2024] [Indexed: 07/03/2024]
Abstract
AIMS The World Health Organization (WHO) estimates that 3.5% of the population live with hepatitis B virus (HBV); migrants to Europe are disproportionately affected. UK birth dose HBV vaccination is limited to infants born to those living with HBV (LWHBV). High-risk infants (high maternal infectivity, low birthweight) also receive HBV immunoglobulin (HBIG). The Family Hepatitis Clinic follows infants and those LWHBV working towards WHO goals of combating viral hepatitis by 2030. METHODS A trust-wide electronic note review of outcomes for infants born to those LWHBV (2016-2020). RESULTS Two hundred and eighty-three infants, 134 (47%) females, born to those LWHBV were referred. Two hundred and thirty-one (82%) attended follow-up with a vertical transmission rate of 0%. Twenty (7%) individuals LWHBV received tenofovir disoproxil fumerate in pregnancy; median viral load (VL) at initiation 125 416 376 DNA IU/mL, one having birth VL. Twenty-eight (10%) infants were stratified as high risk and all received HBIG and birth dose vaccination with 9 (32%) subsequently lost to follow-up, compared to 48 (19%) low-risk infants. 267/283 (94%) had birth dose vaccination documented and 206/283 (73%) received at least four vaccine doses. 215/283 (76%) infants had serology by 24 months; 17 (6%) with suboptimal vaccine responses: hepatitis B surface antibody <100 IU/mL. Serology before 18 months resulted in higher rates of maternal hepatitis B core antibody detection (15% vs. 3%). CONCLUSION Prevention of vertical transmission of HBV was universal in those attending, although high-risk infants were more likely lost to follow up. HBV post-vaccine serological protection was comparable with national data from 2021 (77% >4 doses, 77% HBsAb >100).

Antiretroviral adherence among people living with HIV during the postpartum period: a retrospective cohort study at a PMTCT reference center in Rio de Janeiro before and during the COVID-19 pandemic. AIDS Care 2024:1-11. [PMID: 38648527 DOI: 10.1080/09540121.2024.2343590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 02/28/2024] [Indexed: 04/25/2024]
Abstract
Despite success in achieving viral suppression during pregnancy in people living with HIV (PLWH), postpartum adherence remains a challenge. We aimed to describe rates of adherence at a Prevention of Mother-to-Child HIV Transmission (PMTCT) Center before and during the COVID-19 pandemic. This study was conducted from a cohort of PLWH who received prenatal care and were virally suppressed near delivery. We tracked combined antiretroviral therapy (cART) pickups for 12 months and HIV viral load (VL) from 2 to 12 months after delivery. We defined flexible adherence as a monthly pickup of cART and strict adherence as also having VL < 200 copies/mL and at least one maternal HIV VL between two and twelve months postpartum. Pre-pandemic was defined as delivery from March 2017-February 2019 and pandemic as March 2020-February 2022. During the study, 1119 PLWH were followed, and 965 (86%) were suppressed near delivery. There were 511 pre-pandemic and 290 pandemic participants. Adherence rates were 66/511 (13%) and 38/290 (13%), respectively. During the pandemic, more participants conceived using cART and were undetectable at the start of prenatal care; nevertheless, postpartum adherence was no better than pre-pandemic underscoring the need to improve strategies for adherence specific to this subset of PLWH in the postpartum period.

Giuliano M, Orlando S, Andreotti M, Mthiko B, Mphwere R, Kavalo T, Ciccacci F, Marazzi MC, Floridia M. Maternal retention and early infant HIV diagnosis in a prospective cohort study of HIV-positive women and their children in Malawi. Int J STD AIDS 2023; 34:54-61. [PMID: 36285600 PMCID: PMC10658750 DOI: 10.1177/09564624221136647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 10/14/2022] [Accepted: 10/17/2022] [Indexed: 01/04/2023]
Abstract
BACKGROUND Post-partum loss to follow-up and lack of early HIV infant diagnosis (EID) can significantly affect the efficiency of programs for the prevention of mother-to-child transmission. METHODS In a prospective observational study 167 women were enrolled at week 36 of gestation and followed with their infants up to one year after delivery. Retention was defined as the proportion of women who attended the 12 months visit and EID as an HIV PCR test performed within 2 months. Determinants for retention and EID were assessed in univariate analyses and in multivariable logistic regression models. RESULTS Women lost to follow-up (24/167 or 14.4%) had a shorter duration of antiretroviral therapy (ART) at enrolment in comparison to women retained in care (p = 0.025). Lack of EID (occurring in 18.9% of the cases) was directly correlated, although not significantly, with a history of child death (p = 0.071), a higher educational level (p = 0.083), and female infant gender (p = 0.064). CONCLUSIONS Longer duration of ART at enrolment significantly predicted a better post-partum retention, suggesting that specific counselling interventions should be targeted to recent ART initiators. A low proportion of infants did not receive an EID, but predictive factors were difficult to identify.
