Folate levels in children with sickle cell anaemia on folic acid supplementation in steady state and crises at a tertiary hospital in Enugu, Nigeria: a prospective, comparative study.

Introduction: Folic acid supplementation is an integral aspect of the management of children with sickle cell anaemia (SCA) especially in Africa. In spite of this, there have been concerns about lower folate levels, especially during crisis. Aim: To determine red cell folate levels of children with sickle cell anaemia in steady state and during crisis and compare with those with haemoglobin AA genotype. Method: This study was prospective, hospital based, and comparative. Fifty children with sickle cell anaemia were recruited during crises and followed up until they met the criteria for attaining steady state. The controls were fifty children matched with those with SCA for age and gender and had haemoglobin AA genotype. Red cell folate estimation was done with the Electrochemiluminescence Immunoassay (ECLIA) method using the automated Roche Cobas e411 equipment. Results: The median (IQR) red cell folate level in children during sickle cell crisis was 265.95 (134.50) ng/ml, which was significantly lower than the median (IQR) of 376.30 (206.85) ng/ml obtained during steady state. Most children with SCA (41 out of 50) had significantly higher folate levels during steady state (T=1081, Z-score= -4.660, p < 0.001). Median level of red cell folate was lower during anaemic crisis compared to vaso-occlusive crisis, though not significantly so (N(50), U = 214.00, Z-score= -1.077, p = 0.305). The median red cell folate level of normal controls was 343.55 (92.90) ng/ml, which was significantly lower than the 376.30 (206.85) ng/ml obtained during steady state (N(50), U= 209.00, Z-score= -7.177, p <0.001). Conclusion: Median red cell folate levels of the study participants were within normal limits, though most children with SCA had significantly higher levels during steady state compared to crisis. Normal controls had significantly lower red cell folate levels than the children with SCA during steady state.

Relationship between disease severity and folate status of children with sickle cell anaemia in Enugu, South East Nigeria.

BACKGROUND: Repeated crises in children with sickle cell anaemia (SCA), which is a manifestation of disease severity, results in depletion of their minimal tissue folate stores, with higher likelihood of folate deficiency. The study aimed to determine the relationship between disease severity and the folate status of children with SCA attending University of Nigeria Teaching Hospital (UNTH), Enugu. METHODS: This was a hospital based, cross-sectional study conducted between September 2018 and March 2019. One hundred participants were recruited, consisting of 50 children having sickle cell crisis and 50 age and gender matched haemoglobin AA genotype controls. Relevant information was documented using a pretested questionnaire. Sickle cell severity score was determined using frequency of crisis, admissions and transfusions in the preceding one year, degree of liver and splenic enlargement, life-time cummulative frequency of specific complications of SCA, leucocyte count and haematocrit. RESULTS: Folate deficiency was observed in eight percent of the subjects and none of the controls. The difference was not significant (Fisher's exact = 4.167, p=0.117). The odds of being folate deficient was 8.5 times more likely during anaemic crisis than in vaso-occlusive crisis, though not significant (95% C.I 0.05 - 89.750, p = 0.075). The mean SCA severity score was 8.06 ± 3.64, signifying a moderate SCA severity in the study population. There was a no relationship between folate status and severity of SCA (Fisher's exact = 0.054, p = 0.949). CONCLUSION: Folate status in children with SCA is not affected by their disease severity. Therefore, there may be no need for additional folate supplementation with increasing severity of sickle cell anaemia.

Mother-to-child transmission of HIV: the pre-rapid advice experience of the university of Nigeria teaching hospital Ituku/Ozalla, Enugu, South-east Nigeria.

BACKGROUND: Mother-to-child transmission of human immune deficiency virus (HIV) is the most common route of HIV transmission in the pediatric age group. A number of risk factors contribute to the rate of this transmission. Such risk factors include advance maternal HIV disease, lack of anti-viral prophylaxis in the mother and child, mixing of maternal and infant blood during delivery and breastfeeding. This study aims to determine the cumulative HIV infection rate by 18 months and the associated risk factors at the University of Nigeria Teaching Hospital, Enugu. RESULTS: A retrospective study, involving HIV exposed infants seen at the pediatric HIV clinic of UNTH between March 2006 and September 2008. Relevant data were retrieved from their medical records. The overall rate of mother to child transmission of HIV in this study was 3.9% (95% CI 1.1%- 6.7%). However, in children breastfed for 3 months or less, the rate of transmission was 10% (95% CI -2.5%-22.5%), compared to 3.5% (95% CI 0.5%-6.5%) in children that had exclusive replacement feeding. CONCLUSIONS: This retrospective observational study shows a 3.9% cumulative rate of mother-to-child transmission of HIV by 18 months of age in Enugu. Holistic but cost effective preventive interventions help in reducing the rate of mother-to-child transmission of HIV even in economically-developing settings like Nigeria.

Clinical profile and home management of sickle cell-related pain: the Enugu (Nigeria) experience.

OBJECTIVE: To document the pattern of and ability of sickle cell anemic patients to manage painful crises at home. SUBJECT AND METHODS: Confirmed HbSS patients or caregivers attending the University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria, were interviewed, using a questionnaire, on their last painful episode. RESULTS: The limbs were involved in all ages, but involvement of the joints, ribs, and spine was uncommon in patients under 5 years old. Pain started between 6 pm and 12 midnight in 33.3%. Analgesics with or without massage or hydration was mostly used at home. 29% of subjects required hospitalization. CONCLUSION: Patients need better access to more potent analgesics to reduce the burden on the health system.
