ABSTRACT
We examined the prevalence of mental health conditions, social support, and associated factors among adolescents living with HIV. We conducted a cross-sectional analysis with adolescents (ages 9-19) attending a primary care clinic in Johannesburg, South Africa. We analyzed the results of four self-report tools: Children's Depression Inventory-Short, Revised Manifest Anxiety Scale, Child Post-Traumatic Stress Disorder (PTSD) Checklist, and a modified version of the Medical Outcomes Study Social Support Scale. We used robust Poisson regression to quantify the association between social support and mental health. Among 278 adolescents, the majority were perinatally infected with HIV (92%), and had at least one deceased parent (59%). Depression symptom threshold scores were found among 8% of adolescents, and 7% screened positive for symptoms of anxiety. Few (1%) met the criteria for PTSD. Overall, 12% of adolescents screened positive for symptoms of depression, anxiety or PTSD. Older adolescents reported less social support than younger adolescents. Adolescents were less likely to have mental health symptoms if they had higher measures of social support (adjusted Prevalence Ratio 0.38, 95% CI 0.20-0.73). Attention should be paid to social support for adolescents living with HIV as this may play an important role in their mental health.

Background: Hospital studies have demonstrated the usefulness of alternative sampling strategies to expectorated sputum and new diagnostics for the diagnosis of childhood tuberculosis (TB) but there is limited evidence of how these approaches work in the primary-care setting. Aim: To assess the feasibility and yield of a variety of sample types and diagnostic tests for childhood TB at a primary-care clinic. Methods: A prospective cohort of children (<10 years) with signs and symptoms of TB was enrolled at a primary-care clinic in Johannesburg, South Africa. Tuberculin skin testing (TST) and chest X-ray (CXR) were performed in all. In those unable to expectorate, one induced sputum (IS), one ambulatory gastric aspirate (GA) and two nasopharyngeal aspirates (NPA) were collected. Stool was collected from all. Samples were processed for smear microscopy, liquid culture and Xpert MTB/RIF. The Determine TB LAM Ag (LAM) test was used for HIV-positive children. Results: From July 2013-December 2014, 119 children were enrolled, 21 (18%) of whom were HIV-positive. TST was positive in 25/105 (24%) and 70/116 (70%) had a positive CXR. Four (3%) had confirmed TB, 101 (85%) unconfirmed TB and 15 (13%) unlikely TB. Of the 469 samples collected, smear microscopy was positive in none, Xpert was positive in four (<1%) and culture was positive in two (<1%). Three of 11 (27%) HIV-positive patients were positive by LAM. Treatment was commenced in 48/119 (40%). Conclusions: At primary-care, alternative sampling strategies proved feasible but resulted in a low diagnostic yield. Extensive efforts to bacteriologically diagnose children did not contribute to clinical management.

OBJECTIVE: To identify baseline demographic and clinical risk factors associated with poor CD4 and weight response after initiation of antiretroviral therapy (ART) in a cohort of human immunodeficiency virus (HIV)-infected children in KwaZulu-Natal, South Africa. METHODS: We performed a retrospective cohort study of 674 children initiating antiretroviral therapy at McCord and St. Mary's hospitals in KwaZulu-Natal, South Africa, from August 2003 to December 2008. We extracted data from paper charts and electronic medical records to assess risk factors associated with CD4 and weight response using logistic regression. RESULTS: From the initial cohort of 901 children <10 years old initiating ART between August 2003 and December 2008, we analyzed 674 children with complete baseline data. Viral suppression rates (<400 copies/ml) were 84% after six months of therapy and 88% after 12 months of therapy. Seventy-three percent of children achieved CD4 recovery after six months and 89% after 12 months. Weight-for-age Z-score (WAZ) improvements were seen in 58% of children after six months of ART and 64% after 12 months. After six months of ART, lower baseline hemoglobin (p = 0.037), presence of chronic diarrhea (p = 0.007), and virologic failure (p = 0.046) were all associated with poor CD4 recovery by multivariate logistic regression. After 12 months of ART, poor CD4 recovery was associated with higher baseline CD4% (p = 0.005), chronic diarrhea (p = 0.02), and virologic failure (p<0.001). Age less than 3 years at ART initiation (p = 0.0003), higher baseline CD4% (p<0.001), and higher baseline WAZ (p<0.001) were all associated with poor WAZ improvements after 6 months by multivariate logistic regression. CONCLUSION: The presence of chronic diarrhea at baseline, independent of nutritional status and viral response, predicts poor CD4 recovery. Age at initiation of ART is an important factor in early WAZ response to ART, while viral suppression strongly predicts CD4 recovery but not WAZ improvement.

OBJECTIVE: To identify demographic and clinical risk factors associated with mortality after initiation of antiretroviral therapy (ART) in a cohort of human immunodeficiency (HIV) infected children in KwaZulu-Natal, South Africa. METHODS: We performed a retrospective cohort study of 537 children initiating antiretroviral therapy at McCord Hospital in KwaZulu-Natal, South Africa. Data were extracted from electronic medical records and risk factors associated with mortality were assessed using Cox regression analysis. RESULTS: Overall there were 47 deaths from the cohort of 537 children initiating ART with over 991 child-years of follow-up (median 22 months on ART), yielding a mortality rate of 4.7 deaths per 100 child years on ART. Univariate analysis indicated that mortality was significantly associated with lower weight-for-age Z-score (p<0.0001), chronic diarrhea (pâ=â0.0002), lower hemoglobin (pâ=â0.002), age <3 years (pâ=â0.003), and CD4% <10% (pâ=â0.005). The final multivariable Cox proportional hazards mortality model found age less than 3 years (pâ=â0.004), CD4 <10% (pâ=â0.01), chronic diarrhea (pâ=â0.03), weight-for-age Z-score (<0.0001) and female gender as a covariate varying with time (pâ=â0.03) all significantly associated with mortality. CONCLUSION: In addition to recognized risk factors such as young age and advanced immunosuppression, we found female gender to be significantly associated with mortality in this pediatric ART cohort. Future studies are needed to determine whether intrinsic biologic differences or socio-cultural factors place female children with HIV at increased risk of death following initiation of ART.

OBJECTIVE: To evaluate the association between treatment of HIV-tuberculosis (TB) coinfection and primary virologic failure among children initiating antiretroviral therapy in South Africa. DESIGN: We performed a retrospective cohort study of 1029 children initiating antiretroviral therapy at two medical centers in KwaZulu Natal, South Africa, a region of very high TB incidence. METHODS: Data were extracted from electronic medical records and charts and the impact of TB cotreatment on viral suppression at 6 and 12 months was assessed using logistic regression. RESULTS: The overall rate of virologic suppression (<400 HIV RNA copies/ml) was 85% at 6 months and 87% at 12 months. Children who received concurrent treatment for TB had a significantly lower rate of virologic suppression at 6 months (79 vs. 88%; P = 0.003). Those who received nonnucleoside reverse transcriptase inhibitor-based HAART had similar rates of viral suppression regardless of whether they received concurrent TB therapy. In contrast, children who received protease inhibitor-based HAART had significantly lower viral suppression rates at both 6 and 12 months if treated concurrently for TB (P = 0.02 and 0.03). Multivariate logistic regression revealed that age at initiation, protease inhibitor therapy, and TB coinfection were each independently associated with primary virologic failure. CONCLUSION: Concurrent treatment for TB is associated with lower rates of viral suppression among children receiving protease inhibitor-based HAART, but not among those receiving nonnucleoside reverse transcriptase inhibitor-based HAART. Guidelines for the care of young HIV-TB coinfected infants should be continually evaluated, as protease inhibitor-based antiviral therapy may not provide optimal viral suppression in this population.

The treatment of concurrent HIV and tuberculosis (TB) in children <3 years of age has not been well-studied and is complicated by potential drug-drug interactions. The recommended antiretroviral therapy (ART) in coinfected children in South Africa consists of full-strength ritonavir, lamivudine and stavudine. We report on a child initiated on this regimen, during concurrent TB treatment, who promptly developed an adverse reaction, virologic failure and dual-class antiretroviral drug resistance, compromising subsequent salvage ART.

OBJECTIVE: To report the case of a child with a retropharyngeal abscess complicated by carotid artery rupture. DESIGN: Descriptive case report. SETTING: Pediatric intensive care unit of a children's hospital. Patient: A 2-month old girl. INTERVENTION: Surgical ligation of the right common carotid artery was performed. MEASUREMENTS AND MAIN RESULTS: Carotid artery involvement is a rare but life-threatening complication of a retropharyngeal abscess. The child developed carotid arteritis, with pseudoaneurysm formation and acute rupture of the right carotid artery. Surgical ligation was performed, with no accompanying neurologic sequelae. A high index of suspicion is needed for the possibility of carotid space involvement if there is a delay in the resolution of symptoms, despite adequate treatment. CONCLUSION: If a retropharyngeal abscess extends into the carotid space or there is a slow resolution of symptoms, carotid artery involvement must be excluded.
