COVID-19 Infection in Patients with Humoral Immunodeficiency: A Case Series and Literature Review
Abstract
Background: The coronavirus 2019 disease (COVID-19) has infected many individuals worldwide and continues to pose a significant threat to those with weakened immune systems. The data evaluating the clinical outcomes of patients with humoral immunodeficiencies that contract COVID-19 is limited and conflicting.
Objective: To describe the clinical outcomes of COVID-19 infections in patients with primary humoral immunodeficiency and compare results to current literature.
Methods: We conducted a retrospective cohort review on 15 patients with a humoral immunodeficiency defined as Common Variable Immunodeficiency, Specific Antibody Deficiency, or unspecified hypogammaglobulinemia, who contracted COVID-19. Severity scores were determined to evaluate the clinical outcomes of these patients.
Results: Of our 15-patient cohort, 33% of individuals with a humoral immunodeficiency infected with COVID-19 had moderate to severe disease, requiring hospitalization or resulting in death. COVID-19 mortality rate was found to be 7%. All 5 of our patients with severe COVID-19 infection had at least 1 comorbidity or risk factor.
Conclusion: Within our cohort of humoral immunodeficient patients infected with COVID-19, we found a higher rate of moderate to severe COVID-19 infection and worse clinical outcomes, particularly in patients with comorbidities or risk factors.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 19 participants or records.
