RESUMO
BACKGROUND: Neonatal jaundice (NNJ) is a major cause of hospital admission during the neonatal period and is associated with significant mortality. This case-control study with cross-sectional design sought to identify the possible factors associated with neonatal jaundice and assess maternal knowledge level of this condition. METHODS: One hundred and fifty (150) neonates comprising 100 with clinically evident jaundice and 50 without jaundice were conveniently recruited from the Trauma and Specialist Hospital in the Effutu Municipality. Blood samples were collected for the determination of serum bilirubin, glucose-6-phosphate dehydrogenase (G6PD), status and blood group (ABO and Rhesus). Well-structured questionnaire was used to collect maternal and neonate sociodemographic and clinical history. RESULTS: Majority (54%) of neonates developed jaundice within 1-3 days after birth with 10% having it at birth. Duration of labour and neonatal birth weight were associated with neonatal jaundice (P < 0.05). G6PD abnormality was found in 11 (12%) of the neonates with jaundice and ABO incompatibility was present in 18%. Neonates delivered by mothers with formal occupation and those who had prolonged duration of labour were significantly more likely to have neonatal jaundice (OR = 4.174, P = 0.003; OR = 2.389, P = 0.025, resp.). Neonates with low birth weight were also more likely to develop neonatal jaundice (OR = 2.347, P = 0.044). Only 17.3% of mothers had heard of neonatal jaundice. School was the major source of information on neonatal jaundice (34.6%). Majority of participants (mothers) did not know that NNJ can cause damage to other organs in the body (90%). CONCLUSION: Low neonatal birth weight and prolonged duration of labour are associated with neonatal jaundice. Mothers had inadequate knowledge of neonatal jaundice and its causes.
RESUMO
Haemoglobinopathies are common in sub-Saharan Africa. As such haemoglobin electrophoresis are required to inform clinical decision making. However, haemoglobin electrophoresis is an assay that detects protein at either alkaline or acidic pH. Such assays do not interrogate gene sequences but rather the product of a gene. As many post-transcriptional and post-translational modifications impact the final output of the gene (i.e. protein), presentation of such protein-based assay must accurately reflect the technique employed. It is grossly misleading and scientifically inaccurate to report cellulose acetate and/or citrate agar haemoglobin electrophoresis results as 'haemoglobin genotype'. We propose a new paradigm in which haemoglobin electrophoresis data would be presented as 'haemoglobin phenotype' at a specified pH. FUNDING: None declared.
