This study was designed to examine the rates of HIV serostatus disclosure in a sample of HIV-infected children in the state of Karnataka in South India, their reactions to learning their HIV-positive status and the reasons for and barriers to disclosure from the point of view of their caregivers. We enrolled 233 HIV-infected children, aged 5-18 years and their caregivers between July 2011 and February 2013 at HIV clinics in three tertiary care centers. Caregiver interviews included information about demographic characteristics, medical history, type of disclosure to the child and other related factors, including disclosure barriers. Three quarters (n = 185) of the caregivers reported that there had been no disclosure to the child, 15.4% (n = 38) reported partial disclosure (e.g. telling the child he or she had a 'chronic illness') and only 9.7% (n = 24) reported full disclosure, at a mean age of 10.9 (SD: 2.5) years. Caregivers, who planned to disclose in the future, stated on average that 16 years would be the right age. Those who favored a later disclosure reported that they feared strong negative emotional reactions from the child (p = 0.03) and social isolation (p

Adherence to ART, fundamental to treatment success, has been poorly studied in India. Caregivers of children attending HIV clinics in southern India were interviewed using structured questionnaires. Adherence was assessed using a visual analogue scale representing past-month adherence and treatment interruptions >48 h during the past 3 months. Clinical features, correlates of adherence and HIV-1 viral-load were documented. Based on caregiver reports, 90.9 % of the children were optimally adherent. In multivariable analysis, experiencing ART-related adverse effects was significantly associated with suboptimal adherence (p = 0.01). The proportion of children who experienced virological failure was 16.5 %. Virological failure was not linked to suboptimal adherence. Factors influencing virological failure included running out of medications (p = 0.002) and the child refusing to take medications (p = 0.01). Inclusion of drugs with better safety profiles and improved access to care could further enhance outcomes.

The administration of antiretroviral therapy (ART) leads to a rapid reduction in plasma viral load in HIV-1 seropositive subjects. However, when ART is suspended, the virus rebounds due to the presence of a latent viral reservoir. Several techniques have been developed to characterize this latent viral reservoir. Of the various assay formats available presently, the Tat/Rev induced limiting dilution assay (TILDA) offers the most robust and technically simple assay strategy. The TILDA formats reported thus far are limited by being selective to one or a few HIV-1 genetic subtypes, thus, restricting them from a broader level application. The novel TILDA, labelled as U-TILDA ('U' for universal), can detect all the major genetic subtypes of HIV-1 unbiasedly, and with comparable sensitivity of detection. U-TILDA is well suited to characterize the latent reservoirs of HIV-1 and aid in the formulation of cure strategies.

The majority of cases of multisystem inflammatory syndrome in children (MIS-C) manifest non-specific mucocutaneous features. We report the case of a 3-month-old infant presenting with purpura, acral desquamation, and scrotal ulcers. Scrotal ulcers have not been previously reported in MIS-C and add to the spectrum of cutaneous findings associated with the disorder., (© 2021 Wiley Periodicals LLC.)

Background: Most research on adolescent focuses on the risk associated with the illness. Very little research has been carried out on adolescents who have been diagnosed with HIV since birth. With recent advances with ART treatment, life span of these children has increased, and there are lots of protective factors in the environment influencing the resilience. The present study has focused on the resilience among the adolescence with respect to the living arrangement, i.e., in institutionalized care and extended family., Methodology: The current study follows an exploratory research design with the aim of comparing resilience among adolescents living in the institutional setup and those living with their families-parents and extended families. Adolescents receiving ART treatment from a tertiary care hospital constitute universe and were selected purposively for the study. Resilience was measured using Child and Youth Resilience Measure., Results: The results indicated that 70% of the female and majority of them belong to Hindu religion. For majority, the mode of transmission is mother to child. There is no statistically significant difference between the resilience with respect to the living arrangement. However, respondents are resilient., Conclusion: This study has given a space for resilience for different groups of adolescents with respect to the living arrangement., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Indian Journal of Sexually Transmitted Diseases and AIDS.)

Tat/Rev Induced Limiting Dilution Assay (TILDA) is instrumental in estimating the size of latent reservoirs of HIV-1. Here, we report an optimized TILDA containing a broader detection range compared to the reported methods and high sensitivity. Giving priority to sequence conservation, we positioned the two forward primers and the probe in exon-1 of HIV-1. The reverse primers are positioned in highly conserved regions of exon-7. The optimized TILDA detected eight molecular clones belonging to five major genetic subtypes of HIV-1 with a comparable detection sensitivity. Using the optimized assay, we show that only a minor proportion of CD4 + T cells of primary clinical samples can spontaneously generate multiply spliced viral transcripts. A significantly larger proportion of the cells produced viral transcripts following activation. The optimized TILDA is suitable to characterize HIV-1 latent reservoirs and the therapeutic strategies intended to target the reservoir size., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Mehta, Gohil, Mishra, D’silva, Amanullah, Selvam, Pargain, Nala, Sanjeeva and Ranga.)

Children exposed to antiretroviral therapy (ART) are at risk of developing metabolic complications. The association between gene polymorphisms and the development of dyslipidemia in children post ART initiation was studied. Children initiating first-line ART were followed for 2 years at the National Institute for Research in Tuberculosis (Chennai, India), and St. John's Medical College Hospital (Bangalore, India). Clinical examination and fasting serum lipid profiles were measured every 6 months. Participants were genotyped for the polymorphisms in the APOC3 gene (rs2854116; rs2854117, and rs5128). Changes in lipid levels from baseline to months 6, 12, and 24, and the difference between the various genotype variants were analyzed using a modified analysis of variance test. Study enrolled 393 ART-naive HIV-infected children (mean age: 7.6 ± 3 years, mean weight: 18 ± 6) of whom 289 (75%) were started on nevirapine (NVP)-based ART and the remaining 96 (25%) were started on efavirenz-based ART. Only children carrying the GG allele of rs5128 genotype showed a decrease in CD4% and serum triglycerides pre-ART. An increasing trend of total cholesterol, high-density lipoprotein cholesterol (HDL-c), and low-density lipoprotein cholesterol were seen at 6 months in both EFZ and NVP groups, which subsequently stabilized by 12 months irrespective of genotype variants. Genotype variants of APOC3 (rs2854116 and rs2854117 polymorphism) did not show significant changes in serum lipid levels after 24 months of ART, whereas rs5128 polymorphism with "G" allele showed an association with HDL-c levels when on NVP-based ART. Our results suggest that ART plays a major role in normalizing lipid levels in HIV-infected children and APOC3 polymorphisms may not play a significant role in ART-induced dyslipidemia.

Objectives: In India, access to free anti-retroviral therapy has improved the survival of perinatally human immunodeficiency virus (HIV) infected children resulting in the transition of many such children to adulthood. This study aims to understand the social-outcomes and quality of life (QOL) among these adults., Methods: This cross-sectional study was conducted in two tertiary HIV care centers in south India. Perinatally HIV-infected adults aged >18 y were enrolled after obtaining consent. Data were collected by questionnaire based interviews for social outcomes and WHO Quality of Life-BREF (WHOQOL-BREF) for QOL. The social-outcome indicators monitored pertained to family support, educational qualification and occupational, economic, and marital status., Results: The mean age of 107 participants was 18·9 ± 1·1y. The school drop-out rate was 58%. Sixty-two percent were double orphans. Forty-three-percent of the participants were employed with mean per-capita monthly income of Rs.4105 ± 2979 ($65·2 ± 47·3). Fourteen-percent of the participants were married, or in a relationship, and a majority of them, 93%, were females. For QOL, the mean raw score was highest for social relationship (15·79). Relative to studying subjects, a higher proportion of school dropouts scored poorly in social relationship (42% vs.14·8%; Chi-square = 5·28; p = 0·02) and environmental QOL (46% vs.19·6%;Chi-square = 8·09; p = 0·004). The proportion of subjects with a poor physical health QOL was higher among those with a per-capita monthly income above the national average than those with below the national average (69% vs.33·3%; Chi-square = 5·27; p = 0·02)., Conclusions: Though clinico-immunological disease was stable in these perinatally HIV-infected young adults, their social-outcomes pertaining to education, occupation, income, and family support were poor. Factors like education, parental care, and income of the subjects were associated with poor QOL.

Background: Studies relating to long-term virological outcomes among children on first-line antiretroviral therapy (ART) from low and middle-income countries are limited., Methods: Perinatally HIV infected, ART-naive children, between 2 and 12 years of age, initiating NNRTI-based ART during 2010-2015, with at least 12 months of follow-up, were included in the analysis. CD4 cell counts and plasma HIV-1 RNA were measured every 24 weeks post-ART initiation. Immunologic failure was defined as a decrease in the CD4 count to pre-therapy levels or below and virologic failure as HIV-RNA of > 1000 copies/ml at 48 weeks after ART initiation. Genotypic resistance testing was performed for children with virologic failure. Logistic regression analysis was done to identify predictors of virologic failure., Results: Three hundred and ninety-three ART-naïve children living with HIV [mean (SD) age: 7.6 (3) years; mean (SD) CD4%: 16% (8); median (IQR) HIV-RNA: 5.1 (3.5-5.7) log 10  copies/ml] were enrolled into the study. At 48 weeks, significant improvement occurred in weight-for-age and height-for-age z-scores from baseline (all p < 0.001). The immunologic response was good; almost 90% of children showing an increase in their absolute CD4 + T cell count to more than 350 cells/mm 3 . Immunological failure was noted among 11% (28/261) and virologic failure in 29% (94/328) of children. Of the 94 children with virologic failure at 12 months, 36 children showed immunologic failure while the rest had good immunologic improvement. There was no demonstrable correlation between virologic and immunologic failure. 62% had reported > 90% adherence to ART. At the time of virologic failure, multiple NNRTI-associated mutations were observed: 80%-K103N and Y181C being the major NNRTI mutations-observed. Sensitivity (95% CI) of immunologic failure to detect virologic failure was 7% (2-12), specificity 97% (92.4-98.9), PPV 44% (13.7-78.8) and NPV was 72% (65-77.9). There were no statistically significant predictors to detect children who will develop virologic failure on treatment., Conclusions: Considerable immunological improvement is seen in children with ART initiation, but may not be an effective tool to monitor treatment response in the long-term. There is a lack of correlation between immunologic and virologic response while on ART, which may lead to a delay in identifying treatment failures. Periodic viral load monitoring is, therefore, a priority.

Background: As large numbers of children are accessing antiretroviral therapy (ART) in India, we evaluated the dietary intake, growth pattern and risk of metabolic complications like dyslipidemia and insulin resistance among ART-naïve HIV-infected children (CLHIV)., Methods: CLHIV 2-12 years of age, at the time of initiating ART in Chennai and Bangalore, were assessed for their dietary intake, anthropometry, blood CD4 cell count, HIV-1 viral load, fasting serum lipids, glucose and insulin. Homeostatic model assessment-insulin resistance was derived., Results: Three hundred and ninety CLHIV (mean age [SD]: 8 [3] yrs; median viral load: 141,000 [25,876-436,000] copies/mL) were started on non-nucleoside reverse transcriptase inhibitor-based ART. Perinatal infection was documented among 97%. Sixty percent of children were in stage 3 or 4 of World Health Organization clinical staging of HIV/AIDS. Food insecurity was seen in 40% of households. A total of 204 children (52.4%) were stunted and 224 (57.6%) were underweight. Stunting seemed to be more prevalent with increasing age (0-4 years: 48%; >9 years: 60%). Mean intakes of calories, iron, folate and calcium were significantly less than recommended dietary allowances across all age groups. Dyslipidemia, in terms of any abnormal triglycerides or total cholesterol or low-density lipoprotein cholesterol (excluding high-density lipoprotein cholesterol), was seen in approximately 40% of children; insulin resistance in 17%; and C-reactive protein in risk range of metabolic syndrome in 24% of children., Conclusions: In the background of high food insecurity and malnutrition, cardiometabolic abnormalities were seen in 20%-35% of ART-naïve CLHIV in India emphasizing close monitoring of these children for long-term cardiovascular morbidities after initiation of ART.

Objectives: To describe the clinical presentations and molecular diagnosis to aid the clinicians in early diagnosis and appropriate management of Prader-Willi syndrome (PWS)., Methods: Thirty-four clinically diagnosed PWS cases were enrolled after obtaining informed consent/assent. Demographic details, clinical data and anthropometry were recorded using structured proforma. The facial dysmorphology was evaluated. Appropriate genetic testing was performed to confirm the diagnosis., Results: At diagnosis, the most common clinical features included obesity (59%) and short stature (53%). Distinct dysmorphic features were observed in 67%. Neonatal hypotonia with feeding difficulty, delayed development in infancy and childhood behavioral problems were reported in 94%, 94% and 74% respectively. Food seeking behavior and hyperphagia was reported in 67%. Seizures were reported in 47%. All children had underdeveloped external genitalia. Growth hormone (GH) deficiency and impaired glucose tolerance were found in 56% and 50% respectively. Sleep related problems were seen in 67%. Skin and rectal picking were reported in 67%. FISH confirmed micro-deletion was found in 64.7% and abnormal methylation in 35%, of which uniparental disomy was confirmed in 14.7%., Conclusions: Clinical suspicion is vital for early detection of PWS. Confirmation of the diagnosis requires complex multi-tier molecular genetic testing.

Disclosure is an important component of comprehensive management of children living with HIV infection (CLHIV). Many parental concerns are barriers for disclosure in children and only few studies addresses children's perspective on these concerns. Our study aims to understand children's perspective on parental concerns for disclosure and assess the knowledge of HIV. A questionnaire-based cross-sectional study involving CLHIV between 10 and 18 years attending HIV clinic in southern India, was conducted. Data were collected by directly interviewing only the children after obtaining consent from parents/caregivers. Initial open-ended questions were asked to assess the disclosure status and only fully disclosed children were included. Out of 362 enrolled eligible children, the prevalence of full and partial disclosure was 36.7% and 24%, respectively. The mean age of disclosure was 10.4 years (SD ± 2.6) and non-parental family members in an informal setting were the most common source of disclosure (38.3%). Forty-six percentages of parents were unaware of their child's disclosure status. Only 2% had disclosed their status to others who were not part of their care. Among disclosed children, 33.8% became upset or sad upon knowing their status, 12% faced discrimination and 41.4% had complete knowledge about their illness. Though the prevalence of disclosure among CLHIV was high, a majority of them had incomplete knowledge about HIV infection. The parental concerns as reported in literature like the child is too young to disclose, concerns about coping, fear of stigma and discrimination and child disclosing to others were not expressed by children.

Objectives: To study the predictors of mortality and mortality rate in a clinical cohort of Children Living with Human Immunodeficiency Virus infection (CLHIV) from India., Methods: This retrospective cohort analysis of CLHIV aged between 2 mo and 18 y registered during January 2004 through December 2014 at Pediatric Centre of Excellence (PCOE), Indira Gandhi Institute of Child Health (IGICH), was conducted using standard data collection sheet. Demographic and clinical characteristics of all eligible children were analyzed. The primary outcome measured was mortality. The authors also analyzed the cause of death and baseline parameters associated with death to study the predictors of mortality., Results: Out of 1289 CLHIV registered in the PCOE during the study period, 834 (64.7 %) CLHIV, with or without antiretroviral therapy (ART) care, were included. The total time contributed by the study participants was 2872.8 child-years. The mortality rate in these children was 4.9/100 child-years. A significantly higher mortality rate of 28.2 % was found in children < 5 y, 38.6 % in children with advanced WHO clinical staging, 35.2 % among severely immunosuppressed children and 22.3 % in severely malnourished children. Tuberculosis accounted for 28 % of deaths. Univariate Cox regression analysis showed treatment status, age <5 y, baseline WHO clinical stage 3 and 4, severe immune suppression and severe malnutrition were strongly associated with mortality., Conclusions: The mortality rate in the index study cohort was 4.9/100 child-years and tuberculosis was the major cause of death. Younger age, baseline advanced clinical and immunological staging were predictors of mortality. Even though mortality was significantly higher in Pre-ART children, treatment status was not found to be an independent predictor of mortality.

Objectives: To compare the pharmacokinetics of rifampicin (RMP), isoniazid (INH) and pyrazinamide (PZA) between HIV-infected and HIV-uninfected children with tuberculosis (TB) and correlate it with TB treatment outcome., Methods: HIV-uninfected (n = 84) and HIV-infected (n = 77) children with TB receiving standard thrice weekly treatment were recruited from 6 hospitals in India. Semi-intensive pharmacokinetic sampling was performed during intensive phase of TB treatment after directly observed administration of drugs. Drug concentrations were measured by high performance liquid chromatography. INH acetylator status was determined, and nutritional assessment was done. Children were followed-up and treatment outcomes noted., Results: Children with HIV and TB had significantly lower RMP peak concentration (Cmax) (2.6 vs. 5.1 μg/mL; P < 0.001) and exposure [area under the time-concentration curve (AUC0-8); 10.4 vs. 23.4 μg/mL h; P < 0.001] than those with TB. Among HIV-infected children, a significantly higher proportion had stunting (77% vs. 29%; P < 0.001) and underweight (73% vs. 38%; P < 0.001) compared with children with TB. Combining both groups, RMP Cmax (P = 0.001; adjusted odds ratio = 1.437; 95% confidence interval: 1.157-1.784) and PZA Cmax (P = 0.027; adjusted odds ratio = 1.041; 95% confidence interval: 1.005-1.079) significantly influenced treatment outcome., Conclusions: HIV infection was associated with lower Cmax of RMP and INH and AUC0-8 of RMP. Over 90% of children in both groups had subtherapeutic RMP Cmax. Cmax of RMP and PZA significantly influenced TB treatment outcome in children with TB. The findings have important clinical implications and suggest the need to increase anti-TB drug doses in children with HIV and TB.

The objective of this report was to study the pharmacokinetics of rifampin (RMP), isoniazid (INH), and pyrazinamide (PZA) in HIV-infected children with tuberculosis (TB) treated with a thrice-weekly anti-TB regimen in the government program in India. Seventy-seven HIV-infected children with TB aged 1 to 15 years from six hospitals in India were recruited. During the intensive phase of TB treatment with directly observed administration of the drugs, a complete pharmacokinetic study was performed. Drug concentrations were measured by high-performance liquid chromatography. A multivariable regression analysis was done to explore the factors impacting drug levels and treatment outcomes. The proportions of children with subnormal peak concentrations (Cmax) of RMP, INH, and PZA were 97%, 28%, and 33%, respectively. Children less than 5 years old had a lower median Cmax and lower exposure (area under the time-concentration curve from 0 to 8 h [AUC0-8]) of INH (Cmax, 2.5 versus 5.1 μg/ml, respectively [P=0.016]; AUC0-8, 11.1 versus 22.0 μg/ml·h, respectively [P=0.047[) and PZA (Cmax, 34.1 versus 42.3 μg/ml, respectively [P=0.055]; AUC0-8, 177.9 versus 221.7 μg/ml·h, respectively [P=0.05]) than those more than 5 years old. In children with unfavorable versus favorable outcomes, the median Cmax of RMP (1.0 versus 2.8 μg/ml, respectively; P=0.002) and PZA (31.9 versus 44.4 μg/ml, respectively; P=0.045) were significantly lower. Among all factors studied, the PZA Cmax influenced TB treatment outcome (P=0.011; adjusted odds ratio, 1.094; 95% confidence interval, 1.021 to 1.173). A high proportion of children with HIV and TB had a subnormal RMP Cmax. The PZA Cmax significantly influenced treatment outcome. These findings have important clinical implications and emphasize that drug doses in HIV-infected children with TB have to be optimized., (Copyright © 2015, American Society for Microbiology.

In this retrospective study, incidence of nevirapine (NVP) toxicity in children who were switched from efavirenz (EFV) to NVP (treatment experienced [TE] group) was compared with that of children who had started NVP-based antiretroviral therapy directly (treatment naïve [TN] group). This study also identified risk factors associated with development of NVP toxicity in children. The incidence and risk of developing NVP toxicities were significantly higher in TE when compared to TN group. Median duration of onset of NVP toxicity from the initiation was 2.14 and 3.84 weeks in TE and TN children, respectively. Mean CD4 count was found to be significantly higher in children who developed toxicity (577 ± 81 cells/µL) as compared to the children who did not develop toxicity (403 ± 29 cells/µL). Similarly, children in TE group who developed NVP toxicity had higher mean CD4 cell count than children in TN with NVP toxicity. The risk factors for the development of NVP toxicity include female gender with CD4 count >250 cells/μL and TE children especially girls with CD4% >15% and boys with CD4 count >400 cells/μL. To conclude, the higher incidence of NVP toxicity among TE group warrants a cautious approach while switching the NVP- from EFV-based therapy.
