Alterations of Hematological Parameters, Hemoglobin and Hematocrit With Liver Enzymes, Aspartate Transaminase and Alanine Transaminase Among Patients With Chronic Kidney Disease Undergoing Hemodialysis in Aljouf Region, Saudi Arabia

BACKGROUND: Anemia results from low kidney production of the erythropoiesis-stimulant erythropoietin. Good liver function is crucial to patients with chronic kidney disease (CKD). This study analyzed two hematological parameters (hemoglobin (Hb) and hematocrit (Ht)) and two liver enzymes, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in patients with CKD undergoing hemodialysis (HD). METHODS: Three hundred and thirty individuals participated in this study. Of them, 159 patients with CKD undergoing HD and 171 healthy individuals as a control group were recruited between January and October 2017. Blood was collected into EDTA containers for complete blood count (CBC) and into additive plain containers for ALT and AST. Relevant case history data were also taken. RESULTS: Obtained results for first and second month of Hb, Ht, AST and ALT of CKD patients undergoing HD were lower (10.2 g/dL and 8.9 for Hb; 27.2% and 24.8% for Ht; 17.8 IU/L and 15.6 IU/L for ALT; 13.9 IU/L and 12.0 IU/L for AST, respectively) (P < 0.05) compared to healthy individuals (15.1 g/dL for Hb; 44.6% for Ht; 28.3 IU/L for ALT and 23.0 IU/L for AST). Furthermore, Hb, Ht, AST and ALT levels were significantly lower (P < 0.05) in their second month compared to the first month. CONCLUSIONS: Anemia might emerge in CKD patients because of low Hb concentration and consequent low Ht. Advanced stage CKD causes decreased AST and ALT, as a result of lipid metabolism disturbances. Therefore, anemia and liver diseases are recommended to be treated in CKD patients to alleviate related complications. Renal transplantation must be performed earlier for them to avoid further complications.
