Correlates of fasting blood glucose among children living with hiv in a Nigerian tertiary hospital: a cross-sectional study.

BACKGROUND: There is growing concern as regards the emergence of metabolic disorders among children living with the Human Immunodeficiency Virus (HIV) worldwide. However, there is paucity of data on the correlates of metabolic indices among HIV-positive children in Africa. METHODS: This study examined 84 HIV-positive children on HAART recruited from the paediatric infectious diseases clinic of the University of Nigeria Teaching Hospital for blood glucose levels using finger-prick testing with an Accu-check glucose meter and test strips. Clinical information was obtained via clinical history and medical records. Data was analyzed to examine the relationship between FBG and the classes of HAART, duration of illness and treatment using analysis of variance (ANOVA). RESULTS: FBG was significantly associated with the classes of HAART (x2=12.4, p = 0.017). In addition, there was a significant association between FBG and duration of illness [F(2, 81) = 6.0; P = 0.004], as well as FBG and duration on HAART [F(2, 81) = 7.9; P = 0.001]. However, duration on HAART and type of HAART were the significant predictors of FBG in this study accounting for 10.5% and 4.1% of the variance, respectively. CONCLUSIONS: There is a greater risk of dysglycemia in paediatric patients with a longer cumulative exposure to HAART. Routine blood glucose checks among children on HAART, especially those who have received HAART for a longer duration of time may therefore be useful in their management.

Childhood diabetes: a myth or reality?- perception of the public from a low-income country: a cross-sectional study.

BACKGROUND: The diagnosis of Type 1 diabetes is commonly missed in most health facilities in Nigeria. Adequate knowledge of childhood diabetes is necessary for the recognition and possible intervention for the control of the disease. However, research to assess knowledge deficiencies and their relationship to attitude is lacking in most developing countries including Nigeria. This study intends to survey the beliefs and perceptions of caregivers of children towards diabetes in childhood. It also aims at determining the caregivers' depth of knowledge of diabetes in children, the relationship between knowledge and practices as well as the association between level of education and gender with practices and knowledge. The study outcome will help in the formulation of policy and education of the communities with regards to the preconceived myths and realities of childhood diabetes. METHODS: A descriptive study involving 500 respondents, population groups were selected by multi-staged sampling from different areas in Enugu metropolis, south-East of Nigeria. A validated structured interviewer-administered questionnaire was used. Ethical approval was obtained, and only consenting subjects were interviewed. Data was analyzed with Statistical Package for the Social Sciences (SPSS) version 20. RESULT: Almost all the respondents (99.8%) had heard of diabetes in adults. However, a lower proportion of respondents 43.2% knew about diabetes in childhood. Only 24.8% had good knowledge of the different aspects of diabetes. Although females were more knowledgeable about the effects of healthy life style modifications on diabetes, there was no gender predisposition in knowledge about diabetes in childhood. A positive association existed between knowledge and education [p < 0.001] concerning childhood diabetes. Irrespective of this association 82.6% of the respondents with good knowledge of the disease still had a poor attitude towards healthy life style practices. CONCLUSION: This study has shown that beliefs and perceptions of childhood diabetes among the adult caregivers in Enugu, south - East Nigeria is mostly erroneous and their knowledge deficient. Literacy did not improve both knowledge and attitude to healthy lifestyle practices.

Sociodemographic determinants of glycaemic control among children with type 1 diabetes in South Eastern Nigeria.

INTRODUCTION: diabetic complications have been identified as the major causes of morbidity and mortality in persons with type 1 diabetes mellitus (T1DM). Lack of appropriate glycaemic control is a significant risk factor for the onset and progression of long term complications of diabetes. Identifying the determinants of good glycaemic control is therefore imperative. METHODS: this was a cross-sectional, hospital-based study of children aged 3-18 years with T1DM. Subjects were consecutively enrolled after obtaining consent from their parents and assent from children aged ≥7 years. A questionnaire was completed recording their clinical history and sociodemographic variables. Their HbA1c was estimated and values ≤7.5% was defined as the cut-off for optimal glycaemic control. RESULTS: seventy-one children with T1DM were enrolled for the study. Thirty-eight (53.5%) of them were males. Mean age (years) was 13.7±4. Mean age at onset of diabetes was 11.6 years (range: 3-16 years), mean duration of diabetes was 24.4 months (range: 4-84 months), mean HbA1c value was 10.5% (range: 6.4%-14%); a multivariate logistic regression analysis was performed to identify determinants of optimal glycaemic control. Only caregivers' involvement in diabetes management P<0.016, odd ratio 13.03 (95% CI: 1.60-105.95) was identified as determinant of good glycaemic control. CONCLUSION: our data suggest that of all the sociodemographic factors studied, caregivers' involvement in diabetes management was the only strong determinant for optimal glycaemic control.

The effect of sickle cell anemia on the linear growth of Nigerian children.

OBJECTIVES: Despite the high prevalence of children with sickle cell anaemia (SCA) in West Africa, there is paucity of data on the height velocity and prevalence of growth failure in SCA patients. With advances in clinical care of SCA patients, could there be a spatial and secular trend in the growth pattern of these children? Hence, the compelling needs to embark on this study. The objectives of the study were to determine the prevalence of growth failure among patients with SCA and its correlation with age, gender and age at diagnosis. METHODS: A Prospective longitudinal study of a cohort of sickle cell anaemic paediatric patients from Pediatrics SCA Clinic, University of Nigeria Teaching Hospital, Ituku Ozalla. Patients were enrolled over a period of two years using a non-parametric convenient sampling method. Their heights were measured at baseline, three months, six months and at 12 months intervals and subsequently plotted on a standard WHO growth chart. The height velocities at different monthly intervals were calculated and compared with the WHO standard normal linear growth rates) for children (used as control) to identify those with GF. (i.e. <10th percentile). The main outcome measures were the mean height velocities at different months' intervals calculated and compared using the repeated measurement analysis of variance (ANOVA) and the Wilcoxon signed test. RESULTS: A cohort of 316 children aged 1-18 years with SCA was evaluated with a male preponderance of 161 (57.4%). The mean age and age at diagnosis were 11.04 ± 5.56 and 4.2 ± 1.7 years, respectively. The prevalence of growth failure and short stature was 84.7%. The burden of GF was highest among post-pubertal participants (94.1%). The most important predictor of growth velocity deficit was age (R2=0.045, standard ß coefficient = -0.22, t=-03.51, p=0.001). CONCLUSIONS: The study demonstrated high prevalence of growth failure in children and adolescents with SCA which intensified with advancement in age and older age at diagnosis.

Early signs of microvascular complications in pediatric patients with short duration of type 1 diabetes mellitus seen in southeast Nigeria.

Background: Clinically evident microvascular complications are rarely seen among children and adolescents with type 1 diabetes mellitus (T1DM), although early signs develop during childhood and accelerate during puberty. Aim: The aim of this study was to determine the prevalence of early signs of microvascular complications in children and adolescents aged 9-19 years with a short duration of T1DM by screening for retinopathy and nephropathy. Methods: A cross-sectional study and participants were consecutively enrolled from the Endocrinology Clinic at Federal Teaching Hospital, Abakaliki. Physical examination and mydriatic ophthalmoscopy were conducted. Three early morning spot urine specimens for albumin/creatinine ratio were estimated 3 months apart. Serum creatinine levels were estimated, and the glomerular filtration rate was calculated. Glycosylated hemoglobin (HbA1c) was determined. Results: Twenty-four individuals participated, 15 (62.5%) were male and the mean age at diagnosis was 12.4 ± 2.3 years. The mean duration of diabetes was 23.8 ± 20.6 months. The mean HbA1c was 11.4%. Retinopathy was seen in 16.7%, whereas 33.3% had microalbuminuria. Blood pressure range was within the 50th-90th percentile for all the participants. Conclusion: The study outcome demonstrated a high prevalence of early signs of microvascular complications such as retinopathy and nephropathy among youths with short duration of T1DM. Poor glycemic control, if not halted, is associated with early signs of microvascular complications which may become clinically evident; contrary to the belief that they are rare in childhood.

RésuméObjectif: abstrait Déterminer la prévalence des signes précoces de complications microvasculaires chez les adolescents âgés de 9 à 19 ans ayant une courte durée de T1DM par dépistage de la rétinopathie et de la néphropathie. Méthodes: Une étude transversale et des sujets ont été inscrits consécutivement de la clinique d'endocrinologie à l'hôpital fédéral d'enseignement Abakaliki.L'examen physique et l'ophtalmose mydriatique ont été menés. Trois spécimens d'urine de tache tôt le matin pour le rapport d'albumine/créatinine ont été estimés 3 mois d'intervalle.Des niveaux de créatinine de sérum ont été estimés et le taux glomerular de filtration calculé.L'hémoglobine glycosylated (HbA1c) a été déterminée. Résultats: 24 sujets ont participé, Quinze (62,5%) étaient des mâles et l'âge moyen au diagnostic était de 12,4 à 2,3 ans.La durée moyenne du diabète était de 23,8 à 20,6 mois. Leur HbA1c moyen était de 11,4%.La rétinopathie a été vue dans 16.7% tandis que 33.3% a eu le microalbuminuria. La tension artérielle se situe entre le 50e et le 90e percentile pour tous les participants. Conclusion: Les signes de complication microvasculaire se manifestent tôt chez les enfants et les adolescents atteints de TIDM dans le sud-est du Nigeria.Contrairement à la croyance que les complications microvasculaires cliniquement évidentes sont rarement vues parmi des enfants avec T1DM.Un mauvais contrôle glycémique et la puberté sont des facteurs de risque importants.
