Background The best policy to follow when nursing homes are massively hit by SARS-CoV2 is unclear. Aim To describe COVID-19 containment in a nursing home transformed into a caring center. Methods Physicians and nurses were recruited. The facility was reorganized and connected with the laboratory of the reference hospital. Ultrasound was used to diagnose pneumonia. Patients needing intensive care were transferred to the reference hospital. Hydroxychloroquine/azithromycin/enoxaparin were used initially, while amiodarone/enoxaparin were used at a later phase. Under both regimens, methylprednisolone was added for severe cases. Prophylaxis was done with hydroxychloroquine initially and then with amiodarone. Period covered: March 22-July 31, 2020. Results The facility was reorganized in two days. Ninety-two guests of the 121 (76%) and 25 personnel of 118 (21.1%) became swab test positive. Seven swab test negative patients who developed symptoms were considered to have COVID-19. Twenty-seven patients died, 23 swab test positive, 5 of whom after full recovery. Four patients needing intensive care were transferred (3 died). Mortality, peaking in April 2020, was correlated with symptoms, comorbidities, dyspnea, fatigue, stupor/coma, high neutrophil to lymphocyte ratio, C-reactive protein, interleukin-6, pro-calcitonin, and high oxygen need (p ≤ 0.001 for all). Among swab-positive staff, 3 had pneumonia and recovered. Although no comparison could be made between different treatment and prophylaxis strategies, potentially useful suggestions emerged. Mortality compared well with that of nursing homes of the same area not transformed into care centers. Conclusion Nursing homes massively hit by SARS-CoV-2 can become caring centers for patients not needing intensive care.

Background Immune checkpoint inhibitors (ICI) have revolutionized the clinical management of a broad spectrum of solid and hematopoietic malignancies over the past decade. ICI are associated with several Immune-related Adverse Events, among which myocarditis and atrioventricular blocks are uncommon but potentially fatal toxicities. Material and Methods We describe two patients undergoing treatment with PD-1 checkpoint inhibitors for metastatic cancers who developed myositis and myocarditis complicated by complete atrioventricular block (CAVB). The first patient had a history of metastatic sarcomatoid urothelial carcinoma treated with Pembrolizumab. After two cycles, he developed eyelid ptosis and was hospitalized for syncopal episodes due to CAVB associated with ICI myocarditis. The second patient had a history of metastatic melanoma and was hospitalized for myocarditis and myositis after the second infusion of Nivolumab. Results In the first case, high-dose corticosteroid therapy was promptly initiated, with subsequent rapid recovery of sinus rhythm and rapid resolution of symptoms. The second patient, despite high-dose corticosteroid therapy, developed CAVB requiring implantation of a definitive PM. After initiation of mycophenolate mofetil and intravenous immunoglobulin therapy, gradual recovery was observed. Both patients had normal left ventricular function with no wall motion abnormalities. However, speckle tracking echocardiography revealed a normal global longitudinal left ventricular strain (GLS) of -19.8% in patient 1 and a depressed GLS of -14.7% in patient 2, consistent with the different evolution of the two myocarditis. Conclusions We recommend a high degree of caution and awareness to all physicians when treating immunotherapy patients. Myocarditis is a relatively rare but potentially fatal event due to its early onset, non-specific clinical presentation and fulminant progression. GLS may be useful in detecting myocardial damage in these patients. Discontinuation of ICI, cardiac pacing, treatment with high-dose corticosteroids and immunosuppressive agents may improve the outcome.
