Abstract


Background and Objective: Multiorgan failure including liver dysfunction is a common finding in sickle cell anemia (SCA) patients, the cause of which is multifactorial with advancing age said to be a major determinant. There is a paucity of data on liver function among SCA patients in relation to age in northern Nigerian hospitals, including Ahmadu Bello University Teaching Hospital (ABUTH), Zaria. This study was to assess the biochemical liver function tests (LFTs) as they relate to age among SCA patients in steady state, with a view to improving the overall monitoring of these patients.

Subjects and Methods: This study was carried out in ABUTH, Zaria, Northern Nigeria. LFTs were carried out in 100 SCA and 100 apparently healthy participants (controls). The SCA group was made up of fifty adults and fifty children diagnosed of SCA, whereas the control group was made up of fifty adults and fifty children who were apparently healthy and had hemoglobin AA. Paired two‑tailed Student’s t‑test for matched samples and Pearson’s linear correlation statistical methods were employed for the data analysis using Microsoft Office Excel 2007. A P ≤ 0.05 was considered as statistically significant.

Results: The serum concentrations of total bilirubin (TB), alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and AST/ALT ratio were significantly higher in SCA patients compared to the controls (P = 0.001, P = 0.001, P = 0.05, P = 0.05 and P = 0.001, respectively). Serum total protein (TP) and ALB were significantly lower (P = 0.01 and P < 0.05, respectively) in SCA patients compared with the controls. The levels of TB, ALT, AST, ALP, and AST/ALT were significantly lower in SCA adults compared to SCA children, whereas TP and ALB were higher in SCA adults compared to the SCA children. There were significant negative correlations between age and each of TB, ALT, AST, ALP, and AST/ALT, and significant positive correlations between age and each of TP and ALB in SCA patients.

Conclusion: There are mild LFTs derangements in SCA patients even in steady state with the extent of the abnormalities decreasing with advancing age of the patients.
