Iron deficiency, still a rarity in children with sickle cell anemia in Ile-Ife, Nigeria

ABSTRACT In this study, children with sickle cell anemia were evaluated for iron deficiency. Serum ferritin and free erythrocyte protoporphyrin free erythrocyte protoporphyrin (FEP) levels, mean corpuscular volume mean corpuscular volume (MCV) and mean corpuscular hemoglobin mean corpuscular hemoglobin (MCH) were used in determining their iron status. The study was done at Pediatric Hematology Outpatient Clinic of the Obafemi Awolowo University Teaching Hospitals' Complex, Ile-Ife. Forty-eight HbSS subjects in steady state and 48 apparently well age and sex matched HbAA controls were evaluated. Serum ferritin less than 25 ng/dL FEP greater than cut off for age, mean corpuscular volume MCV and mean corpuscular hemoglobin MCH less than cut off for age were regarded as indicating iron deficiency. Serum ferritin values ranged from 34.2 to 3282.9 µg/L, with a mean of 381.2 (1.0), median 180 µg/L; which was significantly higher than the controls (p = 0.000). FEP was lower in the subjects but none was iron deficient compared with the controls. The mean corpuscular hemoglobin MCH of subjects was significantly lower than the controls. Subjects had lower mean corpuscular volume MCV compared with controls. Iron deficiency was not detected in any of the subjects with sickle cell anemia in comparison to a prevalence of 43.75% in the controls. Iron deficiency anemia (IDA) was found in 16.7% of the controls, using the WHO cut off for anemia which is hemoglobin concentration of <11 g/dl. While a high prevalence of iron deficiency was noted in the control group, patients with sickle cell anemia were largely iron sufficient, despite their anemia. Iron supplementation remains unnecessary as part of routine management of children with sickle cell anemia in our practice.

Prevalence, risk factors and short-term outcome of babies with Neonatal Jaundice in a secondary facility with free-health services in South-West, Nigeria

Background: Neonatal Jaundice (NNJ) is a common occurrence in about 60% of term infants and 80% of preterm infants worldwide and a leading cause of hospitalization during the first week of life. Available evidence suggests that low- and middle-income countries (LMICs) bear the greatest burden of severe neonatal jaundice characterized by very high rates of morbidity, mortality and long-term sequel compared to high-income countries (HICs). Aims: To document the prevalence, risk factors and short-term outcome of babies with neonatal jaundice in a secondary health facility with free health services in South-West Nigeria. Method: Babies were recruited from both in-born and out-born arms of the Special Care Baby Unit (SCBU). It was a prospective study of all babies admitted for neonatal jaundice from January to December 2014; the babies were followed up till discharge. Patients' information including socio-demographic characteristics, risk factors, treatment modalities and outcomes were collected and entered directly into an Excel sheet. Results: There were a total of 1,309 admissions: 734 males and 575 females giving a M: F ratio of 1.3:1. NNJ was present in 125 (9.5%) of them. Thirty-five (28%) of the affected babies were preterm babies while 90 (72%) were term babies. Ten (8%) of them presented within the first 24 hours of life, 103 babies (82.4%) presented between 1st and 7th day of life while 12 (9.6%) presented after the 7th day of life. Neonatal sepsis, prematurity, perinatal asphyxia and prolonged rupture of membrane (PROM) were the leading causes and risk factors for NNJ in our setting. One hundred and seven (85.6%) of them had only phototherapy as treatment modality while 18 (14.4%) had exchange blood transfusion (EBT). One hundred and twenty babies (96%) were discharged alive, 5 (4%) had bilirubin encephalopathy and 2 babies (1.6%) died. Conclusion: Neonatal Jaundice is common in our setting with possible dire consequences. Health education of the public on its associated modifiable risk factors is desirable

Serum Vitamin D, Calcium and Phosphate among children with pneumonia

Background:Vitamin D is partly responsible formaintainingcalcium and phosphatehomeostasisbut has been shown to have immune modulatory functions.Objective:To measure serumlevels of vitamin D, and plasma levels of calcium and phosphatein children with pneumonia and compare with those of apparentlyhealthy controls.Methods:A cross-sectional study involving seventy-six childrenwith pneumonia, matched with 76 apparently healthy controls.Results:There was no statistically significant difference in the mean serum vitamin D levels between the cases and the controls (t = 1.190, p = 0.236). The mean serum vitamin D level was significantly higher in childrenwith non-severe pneumonia than in those with severe pneumonia (t = 3.299, p =.002). Themean serum vitamin D level was higher among the controls than those with severe pneumonia (t = 2.674, p = 0.009).The mean plasmacalcium and phosphate levels in the controls were significantly higher than in the cases (t = 2.528, p = .013 and t = 4.594, p < .001 respectively). Plasmacalcium and phosphate levels did not vary with the severity of pneumonia. Pneumonia was independently associated with the occurrence of hypocalcaemia and hypophosphataemia (OR= 4.366, 95% CI = 1.851-10.295, p= 0.001; OR= 7.355, 95% CI = 1.545-35.027, p= 0.01 respectively). Conclusion:Children with severe pneumonia hadlower levels of vitamin D than those with the non-severe disease.Derangements in plasma levels of calcium and phosphateare common in children with pneumonia, and these abnormalities occur independently of low vitamin D levels
