Plasmodium Infection Is Associated with Impaired Hepatic Dimethylarginine Dimethylaminohydrolase Activity and Disruption of Nitric Oxide Synthase Inhibitor/Substrate Homeostasis.

Inhibition of nitric oxide (NO) signaling may contribute to pathological activation of the vascular endothelium during severe malaria infection. Dimethylarginine dimethylaminohydrolase (DDAH) regulates endothelial NO synthesis by maintaining homeostasis between asymmetric dimethylarginine (ADMA), an endogenous NO synthase (NOS) inhibitor, and arginine, the NOS substrate. We carried out a community-based case-control study of Gambian children to determine whether ADMA and arginine homeostasis is disrupted during severe or uncomplicated malaria infections. Circulating plasma levels of ADMA and arginine were determined at initial presentation and 28 days later. Plasma ADMA/arginine ratios were elevated in children with acute severe malaria compared to 28-day follow-up values and compared to children with uncomplicated malaria or healthy children (p<0.0001 for each comparison). To test the hypothesis that DDAH1 is inactivated during Plasmodium infection, we examined DDAH1 in a mouse model of severe malaria. Plasmodium berghei ANKA infection inactivated hepatic DDAH1 via a post-transcriptional mechanism as evidenced by stable mRNA transcript number, decreased DDAH1 protein concentration, decreased enzyme activity, elevated tissue ADMA, elevated ADMA/arginine ratio in plasma, and decreased whole blood nitrite concentration. Loss of hepatic DDAH1 activity and disruption of ADMA/arginine homeostasis may contribute to severe malaria pathogenesis by inhibiting NO synthesis.

Pretreatment and Acquired Drug Resistance in Children With Human Immunodeficiency Virus Type 1 in Jos, Nigeria.

We determined pretreatment and acquired human immunodeficiency virus (HIV) drug resistance among children with HIV type 1 (HIV-1) in Jos, Nigeria. The majority (71%) of those who failed first-line antiretroviral therapy were on a nevirapine-containing regimen. The prevalence of pretreatment (48%) and acquired (76%) HIV drug resistance mutations was high in our study. Wider access to HIV drug resistance testing after treatment failure is necessary to optimize second-line treatment options among children with HIV in Nigeria.

Diagnostic accuracy of Xpert MTB/RIF Ultra for childhood tuberculosis in West Africa - a multicenter pragmatic study.

OBJECTIVE: To evaluate the performance of Xpert Mycobacterium Tuberculosis/rifampicin (MTB/RIF) Ultra (Ultra) for diagnosis of childhood tuberculosis (TB) within public health systems. METHODS: In this cross-sectional study, children aged <15 years with presumptive pulmonary TB were consecutively recruited and evaluated for TB at tertiary-level hospitals in Benin, Mali, and Ghana. Bivariate random-effects models were used to determine the pooled sensitivity and specificity of Ultra against culture. We also estimated its diagnostic yield against a composite microbiological reference standard (cMRS) of positive culture or Ultra. RESULTS: Overall, 193 children were included in the analyses with a median (interquartile range) age of 4.0 (1.1-9.2) years, 88 (45.6%) were female, and 36 (18.7%) were HIV-positive. Thirty-one (16.1%) children had confirmed TB, 39 (20.2%) had unconfirmed TB, and 123 (63.7%) had unlikely TB. The pooled sensitivity and specificity of Ultra verified by culture were 55.0% (95% confidence interval [CI]: 28.0-79.0%) and 95.0% (95% CI: 88.0-98.0%), respectively. Against the cMRS, the diagnostic yield of Ultra and culture were 67.7% (95% CI: 48.6-83.3%) and 70.9% (95% CI: 51.9-85.8%), respectively. CONCLUSION: Ultra has suboptimal sensitivity in children with TB that were investigated under routine conditions in tertiary-level hospitals in three West African countries.

Predictors of hyperlactataemia among children presenting with malaria in a low transmission area in The Gambia.

BACKGROUND: Hyperlactataemia and metabolic acidosis are important risk factors for malaria death, but measuring lactate at the point of care is not financially viable in many resource-poor settings. This study aimed to identify combinations of routinely available parameters that could identify children at high risk of hyperlactataemia. METHODS: Using data from a study of Gambian children aged six months to 16 years with severe or uncomplicated malaria, logistic regression modelling with a forward stepwise model selection process was used to develop a predictive model for hyperlactataemia from routinely available demographic, clinical and laboratory parameters. Potential predictors of hyperlactataemia considered for the modelling process were patient characteristics (age, sex, prior use of anti-malarials, and weight percentile for age), respiratory symptoms (deep breathing, irregular respiration, use of accessory muscles of respiration, lung crepitations, grunting respiration, cough, and age-specific respiratory rate), other clinical parameters recorded at presentation (duration of symptoms, Blantyre coma score, number of convulsions prior to admission, axillary temperature, dehydration, severe prostration, splenomegaly) and laboratory measures from blood tests (percentage parasitaemia, white cell count, lymphocyte count, neutrophil count, monocyte count, platelet count, haemoglobin level, blood glucose level). RESULTS: 495 children were included, and 68 (14%) had laboratory-confirmed hyperlactataemia (lactate > 7 mmol/L). Four features were independently associated with increased hyperlactataemia risk in a multivariable age- and sex-adjusted model: lower Blantyre score (odds ratio (OR) compared to score 5 = 2.68 (95% CI, 1.03-6.96) for score 3-4 and 6.18 (95% CI, 2.24-17.07) for score 0-2, p = 0.001), higher percentage parasitaemia (OR = 1.07 (1.03-1.11) per 0031% increase, p < 0.001), high respiratory rate for age (OR = 3.09 (1.50-6.38) per unit increase, p = 0.002), and deep breathing (OR = 2.81 (1.20-6.60), p = 0.02). Cross-validated predictions from the final model achieved area under the receiver operating characteristic curve of 0.83. CONCLUSIONS: This study identified predictors of hyperlactataemia requiring only simple bedside clinical examination and blood film examination that can be carried out in resource-limited settings to quickly identify children at risk of dangerously raised lactate. A simple spreadsheet tool implementing the final model is supplied as supplementary material.

Immunization status of children 1-5 years old seen at the Emergency Pediatric Unit of a Teaching Hospital in North-Central Nigeria.

Introduction: Advocacy for immunization has been ongoing in various parts of the world to improve immunization uptake amongst children. Annually within the last decade, immunization has been reported to avert over two million deaths globally. This study determined the current immunization status of children 1-5 years of age, the factors affecting immunization uptake and recommends ways of improving immunization uptake among children presenting at an Emergency Pediatric Unit (EPU). Methods: This was a prospective cross-sectional study conducted from 1st October to 30th November 2019. All eligible children aged 1-5 years old seen within the study period whose mothers/caregivers consented to participate in the study were recruited in the EPU of Jos University Teaching Hospital (JUTH), Plateau State, Nigeria. A systematic sampling technique was employed in the selection of caregiver/mother-child pair while data were obtained using an interviewer-administered questionnaire. Results: A total of 191 (76.4%) children were fully immunized for age. Distance to the health facility, experience of vaccine side effects and health workers' attitude were significantly associated with immunization status. Distance to health facility was an independent predictor of complete immunization while short messaging service (SMS) was the most preferred 190 (76.0%) way suggested to improve immunization uptake. Conclusions: This study has brought to light a suboptimal level of full immunization status for age, which can be improved by targeting homegrown interventions at improving accessibility to the facility and addressing adverse events following immunization promptly.

Improving the diagnosis of pulmonary tuberculosis using line probe assay and determining the factors associated with the disease in children in Jos, Nigeria.

INTRODUCTION: Diagnosing tuberculosis (TB), including pulmonary tuberculosis (PTB), in children remains a challenge, partly due to its paucibacillary nature in young children. Data on the use of line probe assay (LPA), on gastric and sputum samples, for diagnosing PTB in children are scarce. We determined the proportion of samples positive for Mycobacterium tuberculosis (MTB) by smear microscopy (SM) and LPA in presumptive PTB cases as well as the factors associated with PTB confirmed by LPA, in children in Jos, Nigeria. METHODS: An observational study in children aged 6 months-16 years. Gastric and sputum samples were examined by SM and by LPA for MTB using GenoType MTBDRplus Ver 2.0 (Hain Lifescience). Multivariate logistic regression was performed to determine the factors associated with PTB. RESULTS: Out of 103 children with presumptive PTB, 47 had confirmed PTB, 26 unconfirmed PTB and 30 unlikely PTB by LPA. In 67 gastric samples, MTB was identified by SM in 2 (3.0%) compared to 28 (41.8%) by LPA while in 31 sputum samples, MTB was identified by SM in 5 (16.1%) compared to 18 (58.1%) by LPA. The factors associated with pulmonary tuberculosis were an abnormal chest X-ray (adjusted odds ratio (AOR))=12.39 [3.75-40.90], p<0.001), sleeping in the same room with more than three persons (AOR=3.30 [1.23-8.85], p=0.018) and sleeping in a room with none or one window (AOR=2.86 [1.03-7.95], p=0.044). CONCLUSIONS: Line probe assay improves the diagnosis of pulmonary TB in children, especially with gastric samples, while an abnormal chest X-ray is a useful adjunct in PTB diagnosis. Avoiding overcrowding and having windows in sleeping rooms are a necessary part of TB prevention.

Long Term Exposure to Tenofovir Disoproxil Fumarate-Containing Antiretroviral Therapy Is Associated with Renal Impairment in an African Cohort of HIV-Infected Adults.

OBJECTIVES AND METHOD: There are growing concerns of tenofovir disoproxil fumarate (TDF)-associated renal toxicity. We evaluated the effect of long-term TDF exposure on renal function in a cohort of HIV-1-infected Nigerians between 2006 and 2015. Multivariate logistic regression was used to identify predictors of renal impairment at different time over 144 weeks of antiretroviral therapy (ART). RESULTS: Data of 4897 patients, median age 42 years (interquartile range: 36-49), and 61% females were analyzed. The prevalence of renal impairment increased from 10% at week 24 to 45% at 144 weeks in TDF-exposed participants compared to an increase from 8% at 24 weeks to 14% at 144 weeks in TDF-unexposed participants. Tenofovir disoproxil fumarate exposure predicted the risk of renal impairment at 144 weeks of ART (odds ratio: 2.36; 95% confidence interval: 1.28-4.34). CONCLUSION: Long-term exposure to TDF-based ART significantly increases the likelihood of renal impairment. The continued use of TDF-based regimen in our setting should be reviewed. We recommend the urgent introduction of tenofovir alafenamide-based regimen in the HIV treatment guidelines of Nigeria and other resource-limited countries.

Serum lipid and glucose profiles in HIV-positive Nigerian children.

OBJECTIVES: To describe the fasting serum lipid and glucose profiles of HIV-positive Nigerian children and determine the prevalence and risk factors for dyslipidaemia and hyperglycaemia, which are risk factors for cardiovascular diseases. METHODS: This was a comparative cross-sectional study carried out at the Paediatric Infectious Disease Clinic (PIDC) of the Jos University Teaching Hospital (JUTH) for HIV-positive children and at two primary schools in Jos for HIV-negative children as controls. One hundred and forty-two HIV-positive children aged 6-18 years and an equal number of controls were studied by determining their fasting serum lipid and glucose levels. The prevalence of dyslipidaemia and hyperglycaemia was determined and their risk factors obtained using multivariate logistic regression. P values of less than 0.05 were considered statistically significant. RESULTS: Mean triglyceride levels were significantly higher in HIV-positive children compared with controls at 87.2 mg/dL (95% confidence interval [CI] 79.4-95.0) and 68.1 mg/dL (95% CI 62.5-72.7), respectively (P<0.001). There were no significant differences in mean glucose levels. Dyslipidaemia was significantly higher in HIV-positive children (21.8%) compared with controls (12.7%; P=0.04). Total serum cholesterol was elevated in 17 (12.0%) HIV-positive participants compared with seven (4.9%) of controls (P=0.02). Children on lopinavir/ritonavir (LPV/r) and those with no significant or mild disease had a significantly higher prevalence of hypercholesterolaemia (33.3% vs 4.8% and 14.5% vs 0.0%, respectively; P<0.001). CONCLUSION: HIV-positive children on antiretroviral (ARV) drugs, especially LPV/r, should have their lipids regularly monitored as those with dyslipidaemia stand the risk of subsequently developing cardiovascular diseases.

Changes in the haematological parameters of HIV-1 infected children at 6 and 12 months of antiretroviral therapy in a large clinic cohort, North-Central Nigeria.

BACKGROUND: Prior to commencing antiretroviral therapy (ART), haematological abnormalities are a common occurrence in individuals diagnosed with human immunodeficiency virus (HIV). In the course of receiving ART, these abnormalities usually improve. We determined the prevalence of haematological abnormalities in children diagnosed with HIV-1 and the changes in haematological parameters that occur after 6 and 12 months of being on ART. METHODS: A cross-sectional study of HIV-1 infected children aged 2 months to 15 years, between July 2005 and March 2013, at the paediatric HIV clinic of the Jos University Teaching Hospital, Jos. Median values of repeated measures were compared using the Wilcoxon signed-rank sum test. RESULTS: The prevalence of anaemia, thrombocytopenia and leukopenia among the 941 children studied, prior to ART was 6.4%, 7.0% and 8.6%. Median (IQR) haemoglobin (Hb) levels increased from 10 g/dL (9-11 g/dL) at baseline to 11 g/dL (10-12 g/dL) and 11 g/dL (10-12 g/dL) at 6 and 12 months of ART (P<0.001 and P<0.001), respectively, a 10% increase in both cases. Also, platelet count increased from a median of 327×103/µL (243-426×103/µL) at baseline to 333×103/µL (266-408×103/µL) at 6 months and 339×103/µL (267-420×103/µL) at 12 months, representing a 1.8% and 3.7% increase, respectively. The median total white blood cell count decreased from 7.4×103/µL (5.3-9.9×103/µL) at baseline to 5.9×103/µL (4.6-8.0×103/µL) and 5.8×103/µL (4.5-7.5×103/µL) at 6 and 12 months of ART (P<0.001 and P<0.001), a 20.3% and 21.6% decrease, respectively. CONCLUSION: During the 12 months of ART, children in our cohort had significant improvements in haematological parameters such as haemoglobin levels and platelet counts, which would suggest an early positive response to ART.

Mortality among pulmonary tuberculosis and HIV-1 co-infected Nigerian children being treated for pulmonary tuberculosis and on antiretroviral therapy: a retrospective cohort study.

BACKGROUND: Mortality data, including the risk factors for mortality in HIV-infected children with pulmonary TB (PTB) being treated for PTB and who are on antiretroviral therapy (ART), are scarce in Nigeria. We determined the mortality rate and risk factors for mortality among such children, at the pediatric HIV clinic of the Jos University Teaching Hospital (JUTH) in Jos, Nigeria. METHODS: We performed a retrospective cohort study on 260 PTB-HIV-1 co-infected children, aged 2 months to 13 years, being treated for PTB and on ART from July 2005 to March 2013. The mortality rate and associated risk factors were determined using multivariate Cox proportional hazards modelling. RESULTS: The mortality rate for the study cohort was 1.4 per 100 child-years of follow-up. Median follow-up time was 5.2 years (IQR, 3.5-6.0 years) with total study time being 1159 child-years. The median age of those who died was lower than that of survivors, 1.9 years (IQR, 0.6-3.6 years) versus 3.8 years (IQR, 1.8-6.0 years), p=0.005). The majority of the deaths occurred in males (13, 81.2%), those <5 years of age (14, 87.4%) and those who had severe immunosuppression (11, 68.8%). Risk factors for death were age (with the risk of dying decreasing by 25% for every 1 year increase in age, adjusted hazard ratio (AHR)=0.75 [0.58-0.98], p=0.032), male gender (AHR=3.80 [1.07-13.5], p=0.039) and severe immunosuppression (AHR=3.35 [1.16-9.66], p=0.025). CONCLUSION: In our clinic setting, mortality among our PTB-HIV co-infected children being treated for PTB and on ART was low. However, those presenting with severe immunosuppression and who are males and very young, should be monitored more closely during follow-up in order to further reduce mortality.

Antituberculosis drugs and hepatotoxicity among hospitalized patients in Jos, Nigeria.

BACKGROUND: Tuberculosis (TB) could be fatal if left untreated, however, adverse effects of anti-TB medications (anti-TBs) themselves may limit treatment. We determined the incidence and clinical characteristics of hepatotoxicity in hospitalized patients receiving first-line anti-TB treatment. METHODS: A retrospective cohort study of patients aged ⩾18years seen at the medical wards of the Jos University Teaching Hospital from January 2013 to June 2013 was carried out. Data were retrieved for 110 patients who were prescribed anti-TBs. Their demographic and clinical characteristics were described, and the incidence of symptomatic hepatotoxicity determined. The incidence of hepatotoxicity by strict American Thoracic Society criteria (symptomatic hepatotoxicity plus alanine transaminase in IU/L levels >3×upper limit of normal) was also determined. RESULTS: Twenty patients developed symptomatic hepatotoxicity, giving an incidence of 18.2%. Furthermore, 18 (16.4%) patients had hepatotoxicity according to the American Thoracic Society criteria. Those with symptomatic hepatotoxicity unexpectedly had lower baseline alanine transaminase interquartile range (IQR) (35 [16-63] vs. 67 [4-226]; p=.04) and bilirubin (µmol/L): total IQR (15.3 [10.2-74.8] vs. 20.4 [20.4-20.4]; p=.01) and conjugated IQR (7.6 [5.1-34.8] vs. 10.2 [10.2-10.2]; p=.004). However, there were no significant differences in age, sex, body mass index, and duration of anti-TB treatment, human immunodeficiency virus infection status, antiretroviral therapy status, alcohol consumption, and the presence of hepatitis B surface antigen or hepatitis C virus antibody. CONCLUSION: Hepatotoxicity due to first-line anti-TBs, whether based on clinical features alone or backed by liver chemistry, is common among hospitalized patients in our environment. Studies to determine the predictors of hepatotoxicity to guide clinical interventions aimed at the prevention or timely identification of cases are needed.

Prevalence of and risk factors for pulmonary tuberculosis among newly diagnosed HIV-1 infected Nigerian children.

INTRODUCTION: Studies on the prevalence of and risk factors for tuberculosis (TB) among newly diagnosed human immunodeficiency virus (HIV)-infected children in sub-Saharan Africa are scarce and in Nigeria there is paucity of reported data. We determined the prevalence of and risk factors for pulmonary TB (PTB) in newly diagnosed (treatment-naïve) HIV-1 infected children at the pediatric HIV clinic of the Jos University Teaching Hospital (JUTH) in Nigeria. METHODS: We performed a retrospective analysis of 876 children, aged 2 months - 13 years, diagnosed with HIV-1 infection between July 2005 and December 2012, of which 286 were diagnosed with PTB at presentation after TB screening. The study site was the AIDS Prevention Initiative in Nigeria (APIN)-supported Pediatric HIV clinic at JUTH, Jos. A multivariate forward logistic regression modelling was used to identify risk factors for PTB-HIV co-infection. RESULTS: The prevalence of PTB-HIV co-infection was 32% (286/876). Severe immunosuppression (SI) and World Health Organization (WHO) HIV clinical stage 3/4 were identified as independent risk factors for PTB-HIV co-infection in HIV infected children. The odds of PTB-HIV co-infection was increased two-fold in HIV-infected children with WHO clinical stage 3/4 compared to those with stage 1/2 (adjusted odds ratio (AOR) 1.76 [1.31-2.37], p<0.001) and 1.5-fold in children with SI compared to those without SI (AOR 1.52 [1.12-2.06], p=0.007). CONCLUSION: In our setting, the burden of PTB was high among newly diagnosed HIV-infected children, and late WHO HIV clinical stage and severe immunosuppression were associated with PTB-HIV co-infection. Therefore there is a clear need to improve strategies for early diagnosis of both HIV and PTB to optimize clinical outcomes.

Factors associated with antiretroviral treatment interruption in human immunodeficiency virus (HIV)-1-infected children attending the Jos University Teaching Hospital, Jos, Nigeria.

BACKGROUND: Interrupting anti-retroviral therapy (ART) for any number of reasons is an indication of a compromised adherence to ART. Several factors, including the pill burden from other drugs used in treating co-infections in children with human immunodeficiency virus (HIV), may influence ART adherence. The aim of this study was to identify the factors associated with ART interruption in HIV-1-infected children. MATERIALS AND METHODS: A retrospective cohort study analysing data on 580 children consecutively enrolled on ART between February 2006 and December 2010 at the paediatric HIV clinic of Jos University Teaching Hospital (JUTH), Jos. Subjects were children aged 2 months - 15 years diagnosed with HIV-1 infection and on first-line ART. Cotrimoxazole prophylaxis was usually commenced at diagnosis while awaiting ART commencement. Children diagnosed with tuberculosis (TB) were also placed on multiple individual anti-TB drugs. STATISTICAL ANALYSIS USED: A comparison of the data on children with and without ART interruption was made. Variables associated with ART interruption in a univariate analysis were fit in a multivariate logistic model to determine the factors that were associated with ART interruption. RESULTS: Children on anti-TB drugs were twice more likely to interrupt ART compared to those who were not, (adjusted odds ratio, AOR = 1.84 (1.03-3.28); P = 0.04). But children on cotrimoxazole prophylaxis had a 57% reduction in the odds of interrupting ART compared to those who were not, (AOR = 0.43 (0.20-0.93); P = 0.03). CONCLUSION: Children on ART and also taking multiple individual anti-TB drugs should be monitored closely for ART adherence. Cotrimoxazole prophylaxis should be encouraged in children diagnosed with HIV while awaiting ART commencement as this may prime them for a better ART adherence.

Mother-to-Child Transmission Outcomes of HIV-Exposed Infants Followed Up in Jos North-Central Nigeria.

OBJECTIVE: Since 2010, Nigeria has adopted World Health Organization (WHO) 'Option B' which requires administration of triple antiretroviral prophylaxis or treatment (ART) to all HIVinfected pregnant women. We studied the transmission outcomes of HIV-exposed children up to 18 months of age. DESIGN: This was a retrospective, observational study of HIV-infected pregnant women and their exposed infants who accessed prevention of mother to child transmission (PMTCT) services at Jos University Teaching Hospital, Jos, North-central Nigeria. METHODS: HIV-infected women were enrolled during antenatal care or at labor/delivery between January 1, 2010 and December 31, 2012. Antiretroviral (ARV) prophylaxis/therapy was provided according to the 2010 Nigerian PMTCT guidelines (adapted WHO 2010 guidelines); Infant HIV diagnosis was performed at 6 weeks and at 6 months. HIV antibody diagnosis was used for exposed children at 18 months. RESULTS: A total of 996 HIV-exposed children were followed up. Of those children, 140 (14.1%) were lost to follow up by 18 months of age. Twelve children (1.4%) died (all HIV negative) before 18 months of age and six infants (0.7%) were confirmed to be HIV-infected (4 by the age of 6 months and 2 thereafter) and were referred for treatment. A total of 838 (84.1%) children tested HIV negative at 18 months and were discharged. Mother-to-child transmission (MTCT) of HIV by 18 months was lower among women on ART before pregnancy compared to those women who started ART/Triple ARV prophylaxis during pregnancy/delivery. (0.4%; 3/700 vs 2.0%; 3/150 P=0.05). Home delivery was associated with higher transmission than facility delivery (p=0.03). Mode of delivery or method of infant feeding had no significant impact on vertical transmission by 18 months. CONCLUSION: In North-central Nigeria where HIV is prevalent, ART started before pregnancy is enormously effective in preventing mother-to-child transmission. Adoption of WHO 'Option B+' deserves serious consideration in such settings.

Predictors of Mortality in a Clinic Cohort of HIV-1 Infected Children Initiated on Antiretroviral Therapy in Jos, Nigeria.

BACKGROUND: Mortality among human immunodeficiency virus-1 (HIV-1) infected children initiated on antiretroviral therapy (ART) though on a decline still remains high in resource-limited countries (RLC). Identifying baseline factors that predict mortality could allow their possible modification in order to improve pediatric HIV care and reduce mortality. METHODS: We conducted a retrospective cohort study analyzing data on 691 children, aged 2 months-15 years, diagnosed with HIV-1 infection and initiated on ART between July 2005 and March 2013 at the pediatric HIV clinic of Jos University Teaching Hospital. Lost to follow-up children were excluded from the analyses. A multivariate Cox proportional hazards model was fitted to identify predictors of mortality. RESULTS: Median follow-up time for the 691 children initiated on ART was 4.4 years (interquartile range (IQR), 1.8-5.9) and at the end of 2752 person-years of follow-up, 32 (4.6%) had died and 659 (95.4%) survived. The mortality rate was 1.0 per 100 child-years of follow-up period. The median age of those who died was about two times lower than that of survivors [1.7 years (IQR, 0.6-3.6) versus 3.9 years (IQR, 3.9-10.3), p<0.001]. On unadjusted Cox regression, the risk of dying was about three and half times more in children <5 years of age compared to those >5 years (p=0.02) Multivariate modeling identified age as the main predictor of death with mortality decreasing by 24% for every 1 year increase in age (Adjusted Hazard Ratio (AHR)=0.76 [0.62-0.94], p=0.013. CONCLUSION: The lower mortality rate for our study suggests that even in RLC, mortality rates could be reduced given a good standard of care. Early initiation of ART in younger children with close monitoring during follow-up could further reduce mortality.
