RESUMO

Mother to child transmission (MTCT) of human T-cell lymphotropic virus (HTLV)-1 is associated with increased risk of adult T-cell leukemia and can be unrecognized without routine antenatal screening. We assessed the seroprevalence of HTLV-1/2 among pregnant women attending The University Hospital of the West Indies Antenatal Clinic, 2019, and validated a cost-effective strategy to screen antenatal clinic attendees for HTLV-1/2. Residual antenatal samples from 370 women were tested for HTLV-1/2 by chemiluminescence microparticle immunoassay (CMIA). Six samples were confirmed HTLV-1 positive by Western blot (none for HTLV-2) for a prevalence of 1.62%. Four mother-child pairs were able to be recruited for HTLV testing of children, with two children testing HTLV-1/2 positive. Medical records of HTLV-1-infected women revealed that all women breastfed, indicating an unrecognized risk for HTLV MTCT. To assess whether pooling of samples as a cost-reduction strategy could be introduced, we pooled all antenatal samples received between November and December 2021 into 12 pools of eight samples/pool. Two pools were CMIA positive, and de-pooling of samples identified two CMIA-positive samples (one per pool), both confirmed as HTLV-1 by Western blot. These results indicate that HTLV-1 remains prevalent in pregnant Jamaican women and that sample pooling can be a cost-effective strategy to limit MTCT in Jamaica.

RESUMO

BACKGROUND: There is growing evidence of the benefits of mobile health technology, which include symptom tracking apps for research, surveillance, and prevention. No study has yet addressed arbovirus symptom tracking in pregnancy. OBJECTIVE: This study aimed to evaluate the use of a smartphone app (ZIKApp) to self-report arbovirus symptoms and pregnancy complications and to assess compliance with daily symptom diaries during pregnancy in a cohort of women in an arbovirus-endemic, subtropical, middle-income country (Jamaica). METHODS: Pregnant women aged ≥16 years, having a smartphone, and planning on giving birth at the recruiting center were enrolled between February 2020 and July 2020. ZIKApp comprised a daily symptom diary based on algorithms to identify potential episodes of arbovirus infection and pregnancy complications. Sociodemographic, epidemiological, and obstetric information was collected at enrollment, with additional review of medical records, and users' perception was collected through an exit survey. Descriptive analyses and logistic regression analysis of possible factors associated with diary adherence were performed. RESULTS: Of the 173 women enrolled, 157 (90.8%) used ZIKApp for a median duration of 155 (IQR 127-173) days until pregnancy end, 6 (3.5%) used the app for <7 days, and 10 (5.8%) exited the study early. For each successive 30-day period from enrollment up to 150 days after enrollment, of these 157 women, 121 (77.1%) to 129 (82.2%) completed their daily symptom diary; 50 (31.8%) to 56 (35.7%) did so on the same day. Overall, 31.8% (50/157) of the women had good adherence to diary reporting (ie, they completed the task on the same day or 2 to 3 days later for ≥80% of the days enrolled). There were 3-fold higher odds of good adherence for participants aged >34 years versus those aged 25 to 29 years (adjusted odds ratio 3.14, 95% CI 1.10-8.98) and 2-fold higher odds for women with tertiary versus secondary education (adjusted odds ratio 2.26, 95% CI 1.06-4.83). Of the 161 women who ever made a diary entry, 5454 individual symptom reports were made (median 17 per woman; IQR 4-42; range 0-278); 9 (5.6%) women reported symptom combinations triggering a potential arbovirus episode (none had an adverse pregnancy outcome) and 55 (34.2%) reported painful uterine contractions or vaginal bleeding, mainly in the month before delivery. Overall, 51.8% (71/137) of the women rated the app as an excellent experience and were less likely to be poor diary adherers (P=.04) and 99.3% (138/139) reported that the app was easy to understand and use. CONCLUSIONS: This pilot found a high adherence to ZIKApp. It demonstrated the feasibility and usability of the app in an arbovirus-endemic region, supporting its future development to contribute to surveillance and diagnosis of arbovirus infections in pregnancy and to optimize maternal care.

RESUMO

INTRODUCTION: Risk factors and outcomes of sexually-acquired human immunodeficiency virus infection were characterized in Jamaican children and adolescents. METHODOLOGY: Management was carried out by multidisciplinary teams in Infectious Diseases clinics during August 2003 through February 2019 using modified World Health Organization HIV criteria. RESULTS: There were 78 clients, aged 6 to 19 years, with females:males = 4:1 (p < 0.05). Sexual-initiation occurred in 60%, 47 before < 16 years (median 13 years, with four < 10 years; females:males = 7:1). Sexual-initiation preceded HIV diagnosis in all cases (median 2 years). Secondary education 93% (69/77) and living with non-parental relatives 17% (13/78) were associated with early sexual-initiation (p < 0.042); as was later imprisonment in 6% (3/52). Other sexually transmitted infections 36% (19/53) were associated with sexual-initiation ≥ 16 years (p < 0.01). Risks for ongoing HIV-transmission included infrequent condom use 74% (39/53), body-piercings 50% (24/48), illicit drug use 37% (28/76), tattoos 36% (19/52), transactional sex 14% (7/53) and pregnancy 56% of girls. 77% (59/77) had Centres for Diseases Control's Category A HIV infection; 82% (61/75) initiated anti-retroviral therapy; 75% (56/75) had first-line drugs, with helper T lymphocyte counts ≥ 500 cells/µL in 61% (48/78) and HIV viral load of < 1,000 copies/µL in 63% (40/64). Complications included dermatological 39% (20/52), respiratory 25% (13/52) and neurological 15% (8/52). Early sexual initiation was associated with depression 43% (33/76; p < 0.004) and suicidal attempt or ideation 23% (18/77; p < 0.096). Four (5%) died. CONCLUSIONS: Sexually transmitted HIV/AIDS in children and adolescents should preempt prompt medical, legal and psychosocial interventions.

RESUMO

Increasing access to antiretroviral therapy in resource-limited settings (RLS) has resulted in the survival of perinatally HIV-infected children into adulthood. We characterized the transition process from pediatric to adult care by conducting semi-structured interviews of HIV-infected adolescents and health care providers in Jamaica. Using an inductive content analytic approach, four themes emerged: (1) Transition should be holistic and a process; (2) Pediatric clinics were like families; (3) Rootedness in the pediatric clinic; and (4) Need for adolescent-centered services to bridge the gap between pediatric and adult-centered services. Adolescent informed- and centered-transition approach may result in better outcomes for HIV-infected adolescents.

RESUMO

ABSTRACT Objective There is a growing body of data that demonstrates increased infectious disease outcomes for HIV-exposed uninfected (HIV-EU) infants as compared to their HIV-unexposed (HU) counterparts. We hypothesized that these HIV-EU infants are at greater risk for infectious morbidity and mortality when compared to the general childhood population. We therefore aimed to characterize infections and growth outcomes among HIV-EU infants in Jamaica during their first two years of life. By identifying these outcomes, specific interventions could be implemented to mitigate this risk of morbidity and mortality. Methods HIV-EU infants born between 1 January 2004 and 31 December 2006 in Kingston, Jamaica, were enrolled and followed in multicenter health facilities, using standardized protocols. HIV status was determined by RNA/DNA polymerase chain reaction (PCR) and confirmatory HIV enzyme-linked immunoassay (ELISA). Data were collected on demographic and anthropometric characteristics, infectious morbidity and mortality, and hospitalizations. Outcomes (incidence of infections and hospitalizations; growth (z scores for weight)) were determined, using univariate analyses. Results Of 195 HIV-EU infants followed for 25.9 months (standard deviation, 10.9 months), 102 (52%) were male, 185 (95%) were non-breast-fed, 161 (83%) experienced at least one infection, and 58 (30%) were hospitalized at least once. Infectious disease incidence per 1 000 child-weeks included upper respiratory tract infection of 7.25 (95% confidence interval (CI): 5.92–8.90), otitis media of 4.12 (3.21–5.20), and acute gastroenteritis (AGE) of 1.92 (1.35–2.65). Hospitalization incidence per 1 000 child-weeks included lower respiratory tract infections (LRTIs) of 0.89 (0.53–1.40), sepsis of 0.48 (0.23–0.89), and AGE of 0.43 (0.20–0.81). These infection incidence rates among the HIV-EU infants were higher than those for published community controls. Among the HIV-EU infants, the low-birthweight ones and those born via cesarean section had significantly higher hospitalization rates from LRTI and sepsis than did published community controls. The mean z score for weight during the infants’ first 6 months ranged from -0.06 to 0.78 in this predominantly non-breast-fed population. That score trended upwards to 24 months of age. Conclusions Infectious disease morbidity was higher but growth was normal in this cohort of HIV-EU non-breast-fed infants, in comparison to published community controls. Specific interventions should be implemented to mitigate the risk in this setting.

RESUMO

Gay and bisexual men in Jamaica encounter stigma and discrimination due to criminalization of and negative attitudes towards same-sex sexuality. Disclosure of sexual orientation may be self-affirming, but could increase exposure to negative responses and stressors. Outcomes of an online survey among 110 gay and bisexual Jamaican men ages 18 to 56 years suggest that disclosure to family is affected by level of economic independence. Furthermore, negative familial responses to sexual identity significantly predicted depression. Social and structural interventions, and efforts to strengthen positive family relationships, are needed to foster an environment that enables well-being among sexual minorities in Jamaica.

RESUMO

This study reports on the drug resistance profiles for HIV-infected pediatrics in Jamaica who have been exposed to antiretroviral therapy (ART). The genetic diversity of HIV-1 found in these patients was also determined using phylogenetic analysis. The protease-reverse transcriptase (Pro-RT) region of the genome was amplified from 40 samples, sequenced, and analyzed for the identification of antiretroviral resistance-associated mutations (RAMs). All isolates belonged to subtype B and 39 possessed multiple RAMs in the reverse transcriptase genes that would compromise the efficacy of drugs being used to treat these patients. Four isolates possessed RAMs in the protease genes. The overall frequency of HIV drug resistance was 95%. The high frequency of drug resistance is supported by epidemiological data that revealed an equally high frequency of treatment failure (98%) among the study participants. The results of this study indicate the urgent need for greater access to drug resistance testing in Jamaica.
