ABSTRACT: Introduction: Haematological disorders are common complications of chronic kidney disease (CKD) leading by anemia which increase with the severity of the disease. Objective: Assess the haematological profile of CKD patients stages 3 to 5 non-dialysed seen at the first nephrology consultation in Cameroon. Patients and Methods: A hospital-based cross-sectional study was conducted from February to July 2018 at the nephrology unit of the Yaounde University Teaching Hospital and Douala General Hospital. All adults’ (≥18 years old) patients who provided a written informed consent and attended their first nephrology consultation with a nephrologist diagnosis of CKD stages 3 to 5 non-dialysed were included. Clinical and paraclinical data (serum creatinine, full blood count, reticulocytes count, iron status, vitamin B12 and folates count, and bleeding time) were collected. Parametric, non-parametric and correlations tests were used to compare variables. Results: We included 105 (59% males) participants with a mean age of 55.2 ± 13.6 years divided into 20 (19%), 36 (34.3%) and 49 (46.7%) respectively in stage G3, G4 and G5 of CKD. The profile of hematological abnormalities was anemia (86.7%), leucopenia (15.2%), hyperleucocytosis (6.7%), thrombopenia (23.8%), thrombocytosis (3.8%) and prolonged bleeding time (13.3%) without any association with the stage of CKD (p > 0.05). The pattern of anemia was mainly normocytic and normochromic (59.3%) and aregenerative (92.3%) with iron deficiency found in 23 (21.9%) participants. There was no case of vitamin B12 and folates deficiency. Prolonged bleeding time was observed in 14 (13.3%) participants with a weak correlation between platelets count and bleeding time (r = 0.122). Conclusion: We observed that aregenerative normocytic normochromic anemia is the leading haematological abnormality during CKD in this setting. None of the full blood count parameters was associated with CKD stages and there was a week correlation between bleeding time and platelet count.
