The prevention and treatment of COVID‐19 in these patients is challenging. This experience, with the limitation of a small number of patients, highlights that early treatment of COVID‐19 can overcome the infection, also in hematological patients. We report five cases of Italian patients (two female, three male, age: 55, 63, 80, 70, and 79 years) with hematological malignancies and confirmed COVID-19 pneumonia, managed with a multidisciplinary therapeutic approach that included antiviral therapy, hydroxychloroquine, antibiotic therapy, and management of comorbidities. Three patients were discharged in good clinical conditions; two died. On March 2020, the World health Organization has characterized coronavirus infectious disease 2019 (COVID-19) as a public health emergency of international concern and defined it a pandemic. 1 In Italy, the most involved regions by COVID-19 are Lombardy, Emilia Romagna, and Veneto. The city of Piacenza (Emilia Romagna region) is very near to the epicenter of the outbreak of COVID-19, and the catastrophic nature of Lombardy's outbreak has been widely published. 2 Recently, a report of the first 25 patients with solid tumor and COVID-19 in a western country (Italy) was published. 3 Hematological patients are known to have a greater sensitivity to infections, caused by the immunosuppression produced by treatments and closely related to their disease. 4 Data on COVID-19 in patients with hematological malignancies are fragmentary and poor. [5] [6] [7] The current paper describes five patients with hematological cancer and COVID-19 infection diagnosed and treated in the district of Piacenza (North Italy). We retrospectively reviewed five patients with hematological malignancies and laboratory-confirmed COVID-19 infection, with reverse transcription-polymerase chain reaction (RT-PCR) in nasal-pharyngeal swabs 8 ; the COVID-19 severity was classified as follow in accordance with the diagnosis and treatment of COVID-19 guidelines 9 : 10 These patients were hospitalized. This study was approved by the Local Ethics Committee. Each patient or legal representative signed an institutional informed consent in which he/she expressed his/her will to allow the use of clinical history data and the publication of these information for research purposes. We report five cases of patients with hematological malignancies and confirmed COVID-19 pneumonia, hospitalized between March and April 2020. All patients' characteristics are reported in Table 1 . The mean age of the patients was 69.4 years (range 55-80), three were male and two female. Three patients had multiple myeloma (MM), one acute myeloid leukemia, and one gastric B-cell lymphoma. Three patients were in active hematological treatment, one in follow-up, and one in supportive therapy. All patients had comorbidities, as shown in Table 1 . At the time of admission, all patients showed an increase of CRP and LDH, two patients had anemia, two thrombocytopenia, and two an increased level of D-dimer ( Table 2) . The immunoglobulin levels were tested in all the five patients, and it was low for everyone. All patients were tested for HIV and were negative. Fever and dyspnea were the most common symptoms at the admission; patients did not report anosmia and ageusia. Typical findings of chest CT images were observed in four patients at hospital admission, and in one patient, chest CT scan was initially negative, but 5 days later it demonstrated bilateral pneumonia. All the patients were treated with antibiotic therapy, three with anticoagulant therapy (enoxaparin), and one patient started treatment with linezolid for evidence of sepsis. Oxygen therapy was required in four patients. Four patients received antiviral treatment, including darunavir/cobicistat (n = 2), darunavir/ ritonavir (n = 1), and lopinavir/ritonavir (n = 1). All the patients received hydroxychloroquine. Three patients received blood transfusion during the hospitalization for anemia, and three patients experienced respiratory failure. Three of them, treated with antiviral therapy and antibiotic, had gradually recovered and were discharged from the hospital. Two patients died for COVID-19 pneumonia. There are few data about the risk of developing COVID-19 in patients with hematological cancers. It is proven that patients with cancers involving the immune system or treated with immunochemotherapy regimen or immunomodulatory drugs, which suppress bone marrow function, are at risk of infections. 10 Low immunoglobulin levels measured in these patients may have contributed to COVID-19 susceptibility. In our case, patients presented with common symptoms of COVID-19, but many patients present with atypical symptoms and some are very difficult to diagnose 11 and require special attention. Studies about patients with COVID-19, evidence variable hematological findings, such as lymphopenia, elevated LDH levels or altered coagulation tests, such as the prothrombin time (PT) and activated partial thromboplastin time (aPTT). 12 Jin and colleagues 5 reported COVID-19 in a patient with chronic lymphocytic leukemia; they emphasized the fact that clinical and biochemical data of COVID-19 might be partly masked by coexisting hematological disease. In this case, all patients presented increased CRP and LDH levels; other anomalies have been highlighted such as thrombocytopenia and anemia but they may be related to therapy of the hematological cancers rather than COVID-19; indeed, case 05, without evidence of active hematological disease and in follow-up, did not present abnormalities of the blood count. Zhou and colleagues 13 evidence that, in COVID-19 patients, D-dimer level higher than 1 mg/mL was an independent risk factor of mortality and our patients 01 and 02 showed increased D-dimer levels, LDH and CRP (Table 2) over the course of illness; however, they recovered and were discharged ( Table 1) . Evidence of abnormal coagulation parameters associated with COVID-19 appeared in early reports from China. Baseline characteristics of the first 99 patients hospitalized in Wuhan found that 36% had elevated D-dimer and increased biomarkers of inflammation including CRP. 14 severe and critical patients with COVID-19, they exhibited a hypercoagulable state, with elevated levels of D-dimer, prolonged prothrombin time, and increased level of fibrinogen; caused by several factors like inflammatory status and aggressive immune response, which leads some patients to develop disseminated intravascular coagulation (DIC). Our data are consistent with data reported by Asakura and colleagues 18 ; they evaluated the pathophysiology of DIC associated with COVID-19 and observed an increased level of D-dimer and fibrinogen related to a patient in hypercoagulable state. Tang and colleagues 19 reported that 71.4% of nonsurvivors and 0.6% of survivors of COVID-19 showed evidence of DIC. In this case reports, all patients treated with anticoagulant therapy had signs and symptoms improvement, in agreement with He and colleagues 7 that early anticoagulation and early thrombolytic agents may provide better prognosis in COVID-19 patients and Singhania and colleagues that recommended prophylactic anticoagulation in all patients with COVID-19 unless contraindicated. 20 Zhou et al 13 reported that COVID-19 patients, with older age and preexisting conditions (diabetes, hypertension, etc), have an increased risk of death. All the cases in this report had comorbidities, for which they received treatment even during hospitalization. Currently, no specific treatment is effective for treating COVID-19, but HCQ with or without antiviral treatment has been incorporated in regional guideline to treat COVID-19 and was performed in our patients. [21] [22] [23] Zhan and colleagues 6 reported the first case of a patient with MM, diagnosed with COVID-19, treated with tocilizumab with resolution of the infectious disease. They observed that patients with MM are at high risk for COVID-19 and treatment difficulties and evidence the need to determine the safety and efficacy of tocilizumab with randomized controlled trial. Two of the five patients of this series died, and they were affected by MM. There are currently no data from rigorously conducted clinical trials evaluating COVID-19 infection in hematological patients. He and colleagues 7 evidence that hospitalized persons with hematological cancers have a similar case rate of COVID-19 compared with normal healthcare providers but have more severe disease and a higher case fatality rate; in their case series, it seems related predominately to bacterial coinfections; also, in case 03 the patient developed sepsis from gram + cluster bacteria which worsened the patient's condition leading to the fatal outcome. Every country is looking for a strategy to manage patients with hematological malignancies that reduce the risk of COVID-19 for patients and optimizes the use of resources, in Seattle (United States) specialists who manage adult patients with hematological malignancies, lay out treatment guidelines with treatment recommendations for different hematological malignancies 24 ; some of the recommended strategies are using oral and outpatient regimens, increasing telemedicine visits, and avoiding or omitting therapies known to be associated with higher risk of viral infections. Experience in managing COVID-19 patients suggests that early screening, diagnosis, and treatment are critical to prevent complications and to improve clinical outcome; Lin and colleagues 25 of the disease, a severe or recovery phase. The immune response depends on different factor: immune system, comorbidities, age, etc, and is concentrated in the first or second phase, but patients with immune dysfunction have a greater risk of aggravation and subsequent death, already in the first phase. There were several limitations to this study: The sample size is small, only five patients with hematological malignancies and COVID-19 were reported, and subject had heterogeneous hematological diagnoses and disease stage. However, patients with hematological cancer can overcame COVID-19 pneumonia when promptly diagnosed and precociously treated as demonstrated in 3 of 5 patients presented here. The three patients that overcame the infection were treated within 3 days from infection; conversely, the patients that died received treatment after 7 and 8 days, respectively, and these data underline the importance of early treatment. 26 Written informed consent was obtained from the patient for publication of this case report and any accompanying images.
