Human papillomavirus infection among adolescents living with HIV: a focus on prevention.

PURPOSE OF REVIEW: To highlight recent data on HPV infection and cervical precancerous lesions in adolescents with HIV, and priorities for primary and secondary HPV prevention. RECENT FINDINGS: Incident and persistent high-risk HPV infections and cervical abnormalities are higher among young women with perinatally acquired HIV compared to their HIV-negative peers; data on HPV among males with perinatally acquired HIV are scarce. HPV vaccination is highly effective in preventing HPV-related disease, but antibody titers may decline in people with HIV. It remains unclear if emerging recommendations to reduce vaccine schedules from three doses to two or one dose are appropriate for children and adolescents with perinatally acquired HIV. Due to higher risks of HPV-related cancers, screening guidelines for cervical cancer differ in their frequency and age at initiation for women with HIV, but there are no recommendations for women with perinatally acquired HIV; nor for anal cancer screening for men with perinatally acquired HIV. SUMMARY: Data on the effectiveness of reduced HPV vaccine schedules in children and adolescents with HIV are needed. Implementation research to guide strategies for vaccination, screening, and treatment should include children, adolescents, and young adults with perinatally acquired HIV to ensure they are not left behind.

Hospitalization among infants who initiate antiretroviral therapy before 3 months of age.

INTRODUCTION: Studies examining hospitalization among infants with HIV in resource-limited settings, in the context of early infant diagnosis and early antiretroviral therapy (ART) initiation, are limited. METHODS: We used routinely collected data on infants who initiated ART aged <3 months (Western Cape province, South Africa; 2013-2017) to describe hospitalization from birth until 12 months post-ART initiation. Record reviews were additionally performed at three tertiary-level facilities. We used mixed-effects Poisson regression to examine factors associated with hospitalization. RESULTS: Among 840 infants, 579 (69%) were hospitalized; 36% had >1 hospitalization. Median age at ART initiation decreased from 57 days (interquartile range [IQR] 22-74; 2013-2015) to 19 days (IQR 5-54; 2016-2017). Early neonatal hospitalization (age <7 days) occurred in 271 infants (32%) and represented 24% of hospitalizations (272/1131). Overall, 443 infants (53%) were hospitalized at age ≥7 days, including 13% with hospitalizations pre-ART initiation, 15% pre and post-ART initiation and 25% post-ART initiation. Excluding early neonatal hospitalizations, initiating ART at older age vs. age <1 week was associated with higher hospitalization rates: adjusted incidence rate ratios (95% confidence interval) were 1.86 (1.31-2.64); 2.31 (1.62-3.29) and 2.47 (1.76-3.46) if ART initiation age was 1-4 weeks; 5-8 weeks and 9-12 weeks respectively. Among infants whose hospital records were reviewed, reasons for early neonatal hospitalizations mostly related to prematurity or low birthweight (n = 46/60; 77%) whereas hospitalizations at age ≥7 days were mostly due to infections (n = 206/243; 85%). CONCLUSIONS: Earlier ART initiation is associated with lower hospitalization rates. High hospitalization rates, despite initiation age <3 months, is concerning.

False-positive rapid diagnostic tests in paediatric and obstetric patients in South Africa.

INTRODUCTION: Providing easily accessible, quick and accurate human immunodeficiency virus (HIV) testing services (HTS) is central to achieving the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets. Rapid diagnostic tests (RDTs) for HIV are affordable and technically easy to perform. Two positive RDTs from different manufacturers are required to make a diagnosis of HIV in South Africa. Difficulty arises when there are discordant results from the two kits. In this case report, we will discuss four instances of false-positive RDTs. PATIENT PRESENTATION: Case 1 is a 10-year-old female, referred for initiation of antiretroviral treatment (ART). She was diagnosed using two of the same brand RDT at her local clinic. Case 2 is a 21-year-old female who presented to obstetric admissions in labour. Case 3 is a 39-year-old female who was screened for HIV during a routine antenatal appointment. Case 4 is a 22-year-old female who was admitted 21 days postpartum with puerperal sepsis. All four cases had discordant RDTs when screened for HIV at our facility. MANAGEMENT AND OUTCOME: The results of all the investigations conducted on all four patients confirmed HIV negative status. The reference laboratory verified the results and reran the RDTs, which remained discordant. This confirmed a false-positive result in all four cases with the screening RDT. CONCLUSION: With high numbers tested and a low yield of new cases, each individual case of discordancy may cause unnecessary distress, confusion and treatment, particularly in high-risk scenarios like pregnancy. Trends of false-positive and discordant RDT results should be monitored and inform HTS guidelines.
