Background: Since the beginning of 2020, the SARS-CoV-2 pandemic has become a serious public health problem. Numerous studies have highlighted the main clinical features of COVID-19, mainly the huge heterogeneity of the clinical manifestations that can vary from asymptomatic infection to serious viral pneumonia with a high mortality rate. The aim of this study was to analyze retrospectively the clinical characteristics and assess the risk factors for mortality in an Italian cohort of patients with COVID-19., Methods: Retrospective analysis including patients with COVID-19 admitted to the Infectious Diseases wards of Azienda Ospedaliera Universitaria Policlinico "Umberto 1", Rome, from March 2020 to May 2020. The data were part of an electronic anonymous web-based database processed by SIMIT (Italian Society of Infectious and Tropical Diseases)., Results: 258 patients were included in the analysis, and 34 (13.2%) died. The median age was 62 (IQR, 52-74), 106 (40%) were women, and 152 (60%) were males, 172 (66.7%) had at least one co-morbidity. The most common signs and symptoms were: fever [221 (85.6%)], cough [135 (52.3%)], and dyspnea [133 (51.5%)]. The PaO2/FiO2 ratio was often altered [352 (IQR, 308-424)]. Lymphopenia [lymphocyte counts, 875/μL (IQR, 640-1250)] and high levels of D-dimer [mg/dL, 874 (IQR, 484-1518)] were found. Non-survivors were older than survivors [median age, 74 (IQR, 67-85)] vs. 61 (QR, 51-72)], mostly men [25 (73.5%)] and more frequently with more than 2 comorbidities [21 (61.8%) vs. 94 (42.1%)]. In the multiple logistic regression model, the variables associated with in-hospital mortality were age [OR, 3.65 (95% CI, 1.22-10.89)], male gender [OR, 2.99 (95% CI, 1.18-7.54)], blood urea [OR, 2.76 (95% CI, 1.20-6.35)] and a low PaO2/FiO2 ratio [OR, 0.28 (95% CI, 0.12-0.62)]., Conclusion: The mortality rate in COVID-19 was 13,2%. The risk factors associated with in-hospital mortality were advanced age, male sex, increased blood urea, and the PaO2/FiO2 ratio reduction.

Drug-induced aseptic meningitis (DIAM) represents a diagnostic challenge since clinical and cerebrospinal fluid (CSF) findings may be indistinguishable from a bacterial meningitis. Intravenous immunoglobulin (IVIg) are commonly used in a variety of diseases, including inflammatory and autoimmune disorders. Although usually well-tolerated, various adverse effects have been reported. DIAM is a serious neurological side effect of IVIg therapy: albeit rare (0.067% of all IVIg infusions), the condition represents an important diagnostic challenge and should be considered by physicians. Here we report a case of an aseptic meningitis induced by IVIg therapy in a child with acute Epstein-Barr virus (EBV) infection and thrombocytopenia.

Dual therapies, including protease inhibitor + maraviroc (MVC), may represent an alternative to traditional regimens for management of HIV infection. The aim of this in vitro study was to assess the effects of darunavir (DRV) alone or in combination with MVC on cell apoptosis and chemotaxis. A significant decrease of cell apoptosis was found after DRV treatment. The addition of MVC to DRV also had an in vitro down-regulating effect on cell migration. The combination of an NRTI-sparing regimen including DRV+ MVC may have a potential role in immune system modulation by the direct down regulation of apoptosis and chemotaxis.
