CRP and anemia: Patients who suffered phagocytic diseases and experienced COVID-19 were maybe more likely to have lymphopenia (n = 5) [43, 77, 90, 101], high C-reactive protein (n = 5) [43, 53, 77, 90, 107], neutropenia (n = 4) [77, 101, 107, 127], high erythrocyte sedimentation rate (n = 4) [48, 77, 90], low haemoglobin (n = 3) [48, 53], high lactate dehydrogenase (n = 3) [53, 90], thrombocytopenia (n = 3) [40, 95], neutrophilia (n = 3) [43, 90, 107], anaemia (n = 3) [53, 95], thrombocytosis (n = 2) [48, 53], elevated prothrombin time (n = 2) [53] and high ferritin (n = 2) [53, 107].
