Retrospective 340 patients with hematological malignancy in Turkey, showing higher mortality with HCQ treatment. Confounding by time is likely because more HCQ patients were earlier in time when overall treatment protocols were significantly worse.
This study is excluded in the after exclusion results of meta analysis: substantial confounding by time likely due to declining usage over the early stages of the pandemic when overall treatment protocols improved dramatically.

Patients with solid malignancies are more vulnerable to SARS-CoV-2 infection than healthy population. The outcome of SARS-CoV-2 infection in highly immunosupressed populations, such as in patients with hematological malignancies is a point of interest.We aimed to analyze the symptoms, complications, intensive care unit (ICU) admission and mortality rates of patients with hematological malignancies infected with SARS-CoV-2 in Turkey. In this multicenter study, we included 340 adult and pediatric patients diagnosed as COVID-19 from March to November. Forty four (12.9%) patients were asymptomatic at diagnosis. In symptomatic patients, fever, cough and dyspnea were observed in 62.6%, 48.8 % and 41.8% of the patients, respectively. Sixty nine (20%) patients had mild SARS-Cov-2 disease, whereas moderate, severe and critical diseases were reported in 101 (29%), 71 (20%) and 55 (16%) patients, respectively. Two hundered fifty one (73.8%) patients were hospitalized for SARS-Cov2. Mortality related to SARS-CoV-2 infection was 26.5% in all cohort; 4.4% in those patients with mild disease, 12.4% in moderate disease and 83% in severe and critical disease. Active hematological disease, lower life expectancy related with primary hematological disease, neutropenia at diagnosis of SARS-CoV-2, ICU admission and firstline therapy used for COVID 19 treatment were found to be related to higher mortality rates. Treatments with hydroxychloroquine alone or in combination with azitromycin were associated with a higher rate of mortality in comparison with favipiravir use.In conclusion, patients with hematological malignancy infected with SARS-CoV-2 have an increased risk of severe disease and mortality.
