Optimizing antiretroviral therapy for children living with HIV: Experience from an observational cohort in Lesotho.

INTRODUCTION: We describe transition of HIV-positive children from efavirenz- or nevirapine-based antiretroviral therapy (ART) to optimal dolutegravir (DTG) or lopinavir/ritonavir (LPV/r) (solid formulation)-based ART in Lesotho. METHODS: We followed a cohort of children less than 15 years of age who were initiated on ART on or after January 1, 2018 from 21 selected health facilities in Lesotho. From March 2020 to May 2022, we collected data retrospectively through chart abstraction and prospectively through caregiver interviews to cover a period of 24 months following treatment initiation. We used a structured questionnaire to collect data on demographics, ART regimen, drug formulations and switches, viral suppression, retention, and drug administration challenges. Data were summarized as frequencies and percentages, using SAS ver.9.4. RESULTS: Of 310 children enrolled in the study, 169 (54.5%) were female, and median age at ART initiation was 5.9 years (IQR 1.1-11.1). During follow-up, 19 (6.1%) children died, 41 (13.2%) were lost to follow-up and 74 (23.9%) transferred to non-study sites. At baseline, 144 (46.4%) children were receiving efavirenz-based ART regimen, 133 (42.9%) LPV/r, 27 (8.7%) DTG, 5 (1.6%) nevirapine; 1 child had incomplete records. By study end, 143 (46.1%) children were receiving LPV/r-based ART regimen, 109 (35.2%) DTG, and 58 (18.7%) were on efavirenz or nevirapine-based regimen. Of 116 children with viral load results after six months or more on a consistent regimen, viral suppression was seen in 35/53 (66.0%) children on LPV/r, 36/38 (94.7%) children on DTG and 19/24 (79.2%) children on efavirenz. CONCLUSION: Following optimal ART introduction in Lesotho, most children in the cohort were transitioned and many attained or maintained viral suppression after transition; however, we recommend more robust viral load monitoring and patient tracking to reduce losses and improve outcomes after ART transition.

Adverse Pregnancy Outcomes Among HIV-positive Women in the Era of Universal Antiretroviral Therapy Remain Elevated Compared With HIV-negative Women.

BACKGROUND: Without treatment, HIV infection in pregnant women is associated with adverse pregnancy outcomes. We compared adverse pregnancy outcomes among HIV-positive women on antiretroviral therapy (ART) and HIV-negative women who enrolled for antenatal care in selected health facilities in Maseru district, Lesotho. METHODS: We enrolled a cohort of HIV-positive and HIV-negative women at their first antenatal visit and followed them through delivery. Study data on miscarriage, stillbirth, preterm birth, low birth weight and birth defects were collected through participant interviews and medical record abstraction. We used the Rao-Scott χ2 test and the t test to assess differences in characteristics and outcomes between HIV-positive and HIV-negative women and generalized estimating equations for multivariable analysis. RESULTS: A total of 614 HIV-positive and 390 HIV-negative pregnant women were enrolled in the study with delivery information on 571 (93.1%) and 352 (90.3%) respectively. In the delivery cohort, the median age at enrolment was 28 years for HIV-positive women and 23 years for HIV-negative women with median gestational ages of 20 and 21 weeks, respectively. A total of 149 singleton pregnancies had documented adverse pregnancy outcomes; 33 (9.6%) HIV-negative pregnancies and 116 (20.6%) HIV-positive pregnancies. Compared with their HIV-negative counterparts, HIV-positive women were more likely to experience an adverse pregnancy outcome, adjusted odds ratio (AOR) 2.6 [95% confidence interval (CI): 1.71-3.97]; an intrauterine death (miscarriage or stillbirth), AOR 2.64 [95% CI: 1.25-5.49]; or a low birth weight delivery, AOR 1.89 [95% CI: 1.16-3.09]. CONCLUSION: Adverse pregnancy outcomes remained 2-3 times higher among HIV-positive women compared with HIV-negative women despite universal ART.

Assessment of Computer Literacy of Nurses in Lesotho.

Health systems worldwide are moving toward use of information technology to improve healthcare delivery. However, this requires basic computer skills. This study assessed the computer literacy of nurses in Lesotho using a cross-sectional quantitative approach. A structured questionnaire with 32 standardized computer skills was distributed to 290 randomly selected nurses in Maseru District. Univariate and multivariate logistic regression analyses in Stata 13 were performed to identify factors associated with having inadequate computer skills. Overall, 177 (61%) nurses scored below 16 of the 32 skills assessed. Finding hyperlinks on Web pages (63%), use of advanced search parameters (60.2%), and downloading new software (60.1%) proved to be challenging to the highest proportions of nurses. Age, sex, year of obtaining latest qualification, computer experience, and work experience were significantly (P < .05) associated with inadequate computer skills in univariate analysis. However, in multivariate analyses, sex (P = .001), year of obtaining latest qualification (P = .011), and computer experience (P < .001) emerged as significant factors. The majority of nurses in Lesotho have inadequate computer skills, and this is significantly associated with having many years since obtaining their latest qualification, being female, and lack of exposure to computers. These factors should be considered during planning of training curriculum for nurses in Lesotho.
