Abstract

Background Haematological abnormalities following renal transplantation are frequently observed and have a significant effect on survival and graft outcomes. The pattern of haematological abnormalities varies globally. Few studies have been conducted in Asian countries. We aimed to evaluate the patterns of haematological abnormalities in post-transplant recipients in our center during the first year after post-renal transplant and the association of post-transplant anemia with graft function. Methods This single-center retrospective study was conducted on renal transplantation recipients between 2014 and 2019. The study included all patients who received kidney transplants from live/cadaveric donors and had follow-up data collected up to 12 months after the transplant. The outcome studied was the prevalence of haematological abnormalities and the association between post-transplant anemia (PTA) and graft function in post-transplant recipients. Results A total of 106 renal transplant recipients were included in the study. The prevalence of PTA was 98% in the first week, 75% at one month, 35% at three months, 32% at six months, and 27% at 12 months. The other cytopenia cases were leukopenia (43.4%), thrombocytopenia (33.2%), and pancytopenia (15.1%). Post-transplant erythrocytosis was observed in 17.9% of patients. 18 patients with severe PTA in the first week of transplant had significant allograft dysfunction (p=0.04). Patients with and without PTA had similar graft functions at six and 12 months (p=0.50). Conclusions Haematological abnormalities are common in renal transplant recipients. PTA is highly prevalent during the first week and improves over time. Other haematological abnormalities observed were leukopenia, thrombocytopenia, pancytopenia, and post-transplant erythrocytosis. Leucopenia was primarily drug-induced, and thrombocytopenia and pancytopenia were frequently caused by infections in our cohort. Additionally, severe PTA was significantly associated with graft dysfunction in the first week post-transplant, whereas similar graft function was observed at 6 and 12 months post-transplant, irrespective of the presence or absence of PTA.
