• Introduction Patients with hematologic disease are at high risk of morbidity and mortality from COVID‐19 due to disease‐inherent and therapy‐related immunodeficiency. Whether infection with the SARS‐CoV2 omicron variant leads to attenuated disease severity in these patients is currently unknown. Methods We assessed clinical and laboratory parameters in 61 patients with underlying hematologic conditions with a SARS‐CoV2 omicron variant infection confirmed by nucleic acid amplification testing. Results Fifty patients reported symptoms of COVID‐19, most commonly fatigue (37 patients, 60.66%) and cough (32 patients, 52.46%). 39.34% of patients reported fever. Dyspnea was reported by 10 patients and 7 patients (11.48%) required oxygen therapy. Anosmia and ageusia were relatively rare, occurring in less than 10% of patients. Severity of SARS‐CoV2 infection could be assessed in 60 patients. Five cases of critical illness leading to ICU admission occurred during the observation period. Overall mortality was 9.84% in this patient cohort, with heterogeneous causes of death. The majority of omicron‐infected hematologic patients experienced mild symptoms or remained asymptomatic. Discussion In this study, symptoms of COVID‐19 tended to be milder than described for previous SARS‐CoV2 variants. However, the extent to which attenuated severity of omicron‐variant SARS‐CoV2 infection is caused by altered viral pathogenicity or pre‐existing host immunity cannot be inferred from our data and should be investigated in larger prospective studies.
