A Comprehensive Study on the Hematological Progression of Sickle Cell Disease Patients with COVID-19 at the Center for Research and Control of Sickle Cell Disease, Bamako

Abstract

The Coronavirus disease 2019 pandemic is a real crisis that has exposed the unpreparedness of many healthcare systems worldwide. Several underlying health conditions have been identified as risk factors, including sickle cell disease, a chronic illness with various complications that can increase the risk of severe COVID-19 infection. Our study aimed to investigate the profile of sickle cell patients diagnosed with COVID-19 and explore any potential relationship between these two conditions. We analyzed data from 11 sickle cell patients who contracted COVID-19 between June and December 2020 and were treated at the CRLD (Center for Sickle Cell Disease and Research). The patients' COVID-19 diagnosis was confirmed using the (Real-Time Reverse Transcriptase-Polymerase Chain Reaction) RT-PCR technique on nasopharyngeal swab samples and/or based on clinical and radiological findings, including CT scans. The patients consisted of 7 males and 4 females, with a mean age of 40 ± 12 years. The sickle cell phenotypes observed were SC (45.4%), SS (36.37%), and Sβ± thalassemia (18.2%). During the COVID-19 infection, we observed a slight increase in white blood cell and platelet counts, but a decrease in mean hemoglobin levels and red blood cells. Only 3 out of 11 patients (28%) had a fever at the time of diagnosis. Three patients required red blood cell transfusions due to severe anemia, and 7 out of 11 patients (63.6%) were hospitalized, with one patient admitted to the intensive care unit due to pulmonary embolism. All patients recovered from COVID-19.
