COVID-19 in a Patient Newly Diagnosed with Chronic Lymphocytic Leukemia

Coronavirus disease (COVID-19) pandemic continues to pose challenges.Patients with Chronic Lymphocytic Leukemia (CLL) have many risk factors that predispose them to a severe course of COVID-19– related illness, including co-morbidities, older age, and higher prevalence of immunodeficiency from leukemia. Case presentation: A 70-year-old man had a 2-day history of nonproductive cough, dysnoea and shortness of breath, myalgias/ arthralgias, and headache. He explained that had 6-7 day that not felt well: fatigue, fever over 38.0°C, renching and night sweats. He has been healthy till now. His finger oxygen saturation on air room was 80%. Chest tomography showed bilateral ground glass opacities with basal pulmonary consolidation and bilateral pleural effusions. The complete blood count showed a high leucocytosis and a rise of absolute lymphocyte count. TR-PCR of swab nasopharyngeal for Sars-Cov-2 resulted negative. Antibody anti-Sars-CoV-2 IgM and IgG resulted negative on admission and positive on discharged day. Conclusions: There are limited cases available regarding the presentation of COVID-19 in CLL patients. For these reasons this patient group is of particular concern. Our aim is to describe a patient diagnosed with COVID-19 induced hyperleucocytosisand newly diagnosed CLL. Keywords: COVID-19; Chronic lymphocytic leukemia; Leucocytosis; Lymphocytosis
