Popis: Introduction: Research has implicated an exaggerated or self-directed immune response as a factor in determining patient outcome in COVID-19. Initial reports identify lymphopenia as having a predictive role in COVID-19 related disease severity.Objective: To document the occurrence of lymphopenia in COVID-19 patients and explore its association with demographic factors and disease course.Materials & Methods: This cross sectional, observational study was conducted at Rehman Medical Institute, Peshawar from May, 2020 to August, 2020. All patients admitted to the hospital with COVID-19 diagnosis were included. Relevant information including demographics, disease severity, laboratory findings & outcomes were noted in a predesigned Performa. The data were analyzed on SPSS 22 for descriptive and comparative statistics; p≤0.05 denoted significance.Results: A total of 216 patients were included, of whom 172 (79.6%) were males. The mean age was 54.61 ± 14.35 years. Classic lymphopenia was found in 67 (31.5%), 66 (31.0%) had borderline lymphopenia, and 80 (37.6%) had no lymphopenia. Of the classic lymphopenia group, 14 (20.9%) had mild disease, 21 (31.3%) had moderate disease, 18 (26.9%) had severe disease & 14 (20.9%) had critical disease. In patients with borderline lymphopenia 31 (47.0%) had mild disease, 17 (25.8%) moderate disease, 14 (21.2%) had severe disease and 04 (6.1%) had critical disease. In patients with no lymphopenia, 32 (40.0%) had mild, 32 (40.0%) had moderate, 14 (17.5%) had severe & 02 (2.5%) had critical disease. Mortality associated with classical lymphopenia was 37.3% (n=25) whereas 43.3% (n=29) patients recovered. Male gender, disease severity and outcome were statistically linked to lymphopenia; no statistical significance was observed with age.Conclusion: A statistically significant association of lymphopenia with severe/critical disease and adverse outcomes was noted.Keywords: Lymphopenia, COVID-19, Pandemic.
