Serum selenium status of HIV-infected children on care and treatment in Enugu, Nigeria

Objective. To compare the selenium status of HIV-infected and HIV-uninfected children. Methods. This was a hospital-based comparative study using a structured questionnaire in the quantitative research domain at the University of Nigeria Teaching Hospital, Ituku/Ozalla, Enugu, Nigeria. Seventy-four HIV-infected children were compared with 74 non-HIV-infected children (35 males and 39 females in each group). The outcome measure was the selenium status of the study participants. Results. The mean (standard deviation (SD)) weight-for-height z-score among the subjects was ­0.18 (1.53) compared with 0.05 (1.68) among the controls (p=0.457). The mean (SD) height-for-age z-score among the subjects was ­1.16 (1.44) compared with 0.06 (1.06) among the controls (p<0.001). Eighteen subjects (24.3%) compared with eight controls (11.4%) were selenium deficient (odds ratio 2.49; 95% confidence interval 1.00 - 6.18; p=0.044). Median CD4 counts of selenium-deficient and non-deficient subjects were 765.5 (range 409 - 1 489) and 694.0 (range 85 - 2 196) cells/µL, respectively (p=0.321). The proportions of selenium deficiency were 26.4% and 22.2% in the highly active antiretroviral therapy (HAART) and pre-HAART groups, respectively (p=0.565). Conclusion. There was a significant difference in the proportion of HIV-infected children who were selenium deficient compared with their uninfected counterparts

Outcomes of Paediatrics HIV care at the University of Nigeria Teaching Hospital, Ituku-Ozalla, Enugu after ten years of service

Background: Antiretroviral therapy is associated with improved survival among HIV-infected children. In Nigeria, HIV treatment scale up was extended to children over a decade ago. This poses new challenges of sustained quality care. Aim: To determine the outcomes for HIV infected children and factors that influenced retention in care at the University of Nigeria Teaching Hospital, Ituku/Ozalla, Enugu.Methods: This was a study of HIV-infected children seen between September 2004 and October 2015 and at the Paediatric HIV clinic of the University of Nigeria Teaching Hospital, Ituku Ozalla, Enugu. Data collected include socio-demographics, HAART regimen and outcomes. Data analysis were done with Statistical Package for Social Sciences (SPSS) version 19 (Chicago IL).Results: Five hundred and nineteen of 555 enrolled children with complete data were included in the data analysis. Two hundred and sixty-seven (51.4%) were females. Three hundred and thirty-nine participants (65.3%) were still in care, 12345 (23.7%) had been lost to follow up, or 22 (4.2%) dead while 35 (6.87%) were transferred out to other health facilities or into the adult ART clinic. Factors associated with retention in care were both parents being HIV positive (p<0.0001), commencement of HAART (p<0.0001) and HIV disclosure status of the child (Fisher's exact Test =0.003).Conclusions: About a quarter of our HIV-infected children were lost to follow up. Prompt initiation of HAART and HIV disclosure will positively influence retention in care

Clinical and Laboratory Profile of ARV Naive HIV Infected Children in the Era of Highly Active Anti-retroviral Therapy in Enugu, South-East Nigeria.

Background: HIV/AIDS is one of the most dynamic epidemic infectious diseases. An estimated 1000 children are newly infected with HIV every day, most of them in sub-Saharan Africa. They often present with various clinical and laboratory manifestations that complicates their management. Objectives: To determine the baseline clinical and laboratory features of HIV-infected children presenting at the University of Nigeria Teaching Hospital (UNTH) Ituku/Ozalla. Methods: Clinical and laboratory data were collected from HIV infected children seen at the Pediatric HIV Clinic of UNTH between July 1st 2010 and June 30th 2012. Clinical and immunological staging of the patients were done using the WHO criteria and data analysis was with SPSS version19. Results: Two hundred and ten children were enrolled into the study. The most common route of HIV infection was vertical transmission (95.2%). Common presenting clinical and laboratory data were: anaemia (92.9%), cough (76.2%), fever (63.3%), popular rash (62.9%) and poor weight gain (61.0%). Thirty-four children (16.2%) each had severe and moderate acute malnutrition while 92 children (43.8%) were stunted. Tuberculosis, hepatitis B and C co-infections were seen in 32.4%, 1.9% and 3.3% of the children respectively. Most of the patients had either a WHO clinical stage III (42.4%) or II (39.0%) disease. Severe immunosuppression based on CD4% or count was seen in more than half of the patients (59.1%). Conclusions: Anaemia was the most common clinical/laboratory finding; followed by cough. Although our patients were likely to present with WHO clinical 2 or stage 3 disease, severe immunological suppression was common.

Prevalence of Human Immunodeficiency Virus Transmission among Transfused Children with Sickle Cell Anemia in Enugu Nigeria

Background: There are a number of routes for human immuno-deficiency virus (HIV) transmission in children. Blood transfusion-related HIV is still common in developing countries like Nigeria especially among high risk children such as those who require repeated blood transfusions. Aim: The aim of this study was to find the prevalence of HIV among transfused children with sickle cell anemia in Enugu. Subjects and Methods: This is a descriptive cross-sectional study conducted at the Sickle Cell Clinic of the University of Nigeria Teaching Hospital; Enugu Sixty-nine transfused children with SCA were enrolled after obtaining consent from their caregivers and assent from older children. Non transfused children matched for age; sex; and social status with the subjects served as control. Voluntary counseling and testing were then provided. Relevant data were obtained using pretested questionnaire. Statistical Package for Social Science (SPSS) version 11 (Chicago; IL) was used for data analysis. The chi-square was used to test for significant association of categorical variables and a P-value of less than 0.05 accepted as significant. Results: HIV antibodies were found in 2.9 (2/69) of the subjects and in 1.6 (1/64) of the control (P = 0.604). All the infected individuals among the subjects were males; had only been transfused once and were from the lower socioeconomic class. The only infected child from the control group was a 7-year-old male and he probably acquired it through vertical transmission since the mother also tested positive to HIV antibody. Conclusions: Blood transfusion is still a risk factor for HIV transmission among children with sickle cell anemia in Nigeria. Strategies that will ensure improved blood transfusion safety at health facilities need to be strengthened

Assessment of Clinical Features and Haematocrit Levels in Detection of Hypoxaemia in Sick Children

This cross-sectional study was to determine the prevalence of hypoxaemia among sick children in EnuguState University Teaching Hospital, Enugu, Nigeria and correlate it with clinical features and haematocrit levels.Ninety-two (92) sick children aged 2­48 months hospitalised at the teaching hospital were recruited after obtaining consent from their carers.The prevalence of hypoxaemia in this study, defined by oxygen saturation of less than 90%, was 13%, and was not dependent on age or sex. A higher proportion of subjects with hypoxaemia had tachypnoea (81.8%),compared with those without (18.2%) (χ² = 1.69; p=0.19).The sensitivity of using tachypnoea alone to predict hypoxaemia was 18.4% while the specificity was 92.3%.The presence of hypoxaemia predicted poor outcome 66.7% of those that died had hypoxaemia. The difference was statistically significant (χ2= 17.9; p=0.00).Tachypnoea had a poor sensitivity although good specificity in predicting hypoxaemia. Presence of hypoxaemia connotes poor prognosis. We recommend that finger pulse oximeters, which are cost effective,should be routinely available at hospitals in developing countries, so that hypoxaemia can be detected earlier and more intensive management instituted
