These are the first 2 patients with inherited CARD9 deficiency and invasive Exophiala disease to be described. CARD9 deficiency should thus be considered in patients with unexplained invasive Exophiala species disease, even in the absence of other infections.

Background Treatment of patients with COVID-19 has included supportive care to mainly relief symptoms of the disease. Although World Health Organization (WHO) has not recommended any effective treatments for COVID-19, there are some reports about use of antiviral drugs. The aim of this study is to determine the effect of Arbidol (ARB) on COVID-19 disease. Methods Using an open-label randomized controlled trial, we examined the efficacy of ARB in patients with COVID-19 in a teaching hospital. One hundred eligible patients with diagnosis of COVID-19 were recruited in the study and assigned randomly to two groups of either hydroxychloroquine followed by KALETRA (Lopinavir/ritonavir) or hydroxychloroquine followed by ARB. The primary outcome was hospitalization duration and clinical improvement 7 days after admission. The criteria of improvement were relief of cough, dyspnea, and fever. Time to relief from fever was also assessed across the two groups. Without any dropouts, 100 patients were entered into the study for the final analysis at significance level of 0.05. Results The mean age of patients was 56.6 (17.8) years and 56.2 (14.8) years in ARB and KALETRA groups, respectively. Majority of patients were male across two groups (66 and 54%). The duration of hospitalization in ARB group was significantly less than KALETRA arm (7.2 versus 9.6 days; P = 0.02). Time to relief fever was almost similar across two groups (2.7 versus 3.1 days in ARB and KALETRA arms, respectively). Peripheral oxygen saturation rate was significantly different after 7 days of admission across two groups (94% versus 92% in ARB and KALETRA groups respectively) (P = 0.02). Based on multiple linear regression analysis, IHD, Na level, and oxygen saturation at the time of admission and type of therapy were the independent adjusted variables that determined the duration of hospitalization in patients with COVID-19. Conclusion Our findings showed that Arbidol, compared to KALETRA, significantly contributes to clinical and laboratory improvements, including peripheral oxygen saturation, requiring ICU admissions, duration of hospitalization, chest CT involvements, WBC, and ESR. We suggest further studies on ARB against COVID-19 using larger sample size and multicenter design. Trial registration IRCT20180725040596N2 on 18 April 2020.

Highlights We described GBS symptoms in three infected patients with COVID-19. The severity and fast progression of GBS linked to COVID-19 seems considerable in mentioned cases. Acute motor and sensory axonal neuropathy (AMSAN) type of GBS was diagnosed according to electrodiagnostic findings in all three cases. GBS is suggested to be considered as a severe and rapid progressive profile in neurologic complications of COVID-19.

Background: Severe coronavirus disease 2019 (COVID-19) may lead to the cytokine storm syndrome which may cause acute respiratory failure syndrome and death. Our aim was to investigate the therapeutic effects of infliximab, intravenous gammaglobulin (IVIg) or combination therapy in patients with severe COVID-19 disease admitted to the intensive care unit (ICU). Methods: In this observational research, we studied 104 intubated adult patients with severe COVID-19 infection (based on clinical symptoms, and radiographic or CT scan parameters) who were admitted to the ICU of a multispecialty hospital during March 2020 in Tehran, Iran. All cases received standard treatment regimens as local protocol (Oseltamivir + hydroxychloroquine + lopinavir/ritonavir or sofosbuvir or atazanavir ± ribavirin). The cases were grouped as controls (n = 43), infliximab (n = 27), IVIg (n = 23) and combination (n = 11). Results: There was no significant difference between controls and treatment groups in terms of underlying diseases or the number of underlying diseases. The mean age (SD) of cases was 72.42 (16.06) in the control group, 64.52 (12.965) in IVIg, 63.40 (17.57) in infliximab and 64.00 (11.679) in combination therapy; (P = 0.047, 0.031 and 0.11, respectively). Also, 37% in the infliximab group, 26.1% in IVIg, 45.5% in combination therapy, and 62.8% in the control group expired (all P < 0.05). Hazard ratios were 0.31 in IVIg (95% CI: 0.12-0.76, P = 0.01), 0.30 in infliximab (95% CI: 0.13-0.67, P = 0.004), 0.39 in combination therapy (95% CI: 0.12-1.09, P = 0.071). Conclusion: According to the findings of this study, it seems that infliximab and IVIg, alone or together, in patients with severe COVID-19 disease can be considered an effective treatment.

Background: Viral hepatitis is one of the health problems which have the effects on the health issues. It seems that hepatitis B virus (HBV) and hepatitis C virus (HCV) infection have negative impacts on the semen quality and male infertility rate. Objective: In this study, we aimed to evaluate the effects of HBV and HCV on sperm quality among Iranian infertile men referred to Royan Institute Reproductive Biomedicine Research Center between 2003 and 2014. Materials and Methods: This retrospective case-control study included 112 HBV positive infertile men and 47 HCV positive infertile men as case group and 112 HBV negative andHCVnegative matched infertile men as a control group. All semen analysis and viral parameters assessment was performed in the central laboratory with the same method and instruments. Results: Sperm count among infertile men with HBV and HCV infection was significantly lower than control group [the mean of the total sperm count 100.95 ± 118.59, 118.22 ± 141.18, 166.27 ± 151.25 (p < 0.001)]. Sperm motility was significantly decreased in HBV and HCV positive men in comparison to the control group [30.97 ± 25.88, 31.09 ± 28.72, 40.87 ± 23.37, respectively (p < 0.007)]. The percentage of normal sperm morphology was significantly higher in control group in comparison to HBV and HCV infected group [the mean of the normal semen morphology 3.23 ± 3.27, 3.70 ± 3.83, 4.51 ± 3.15 p < 0.015]. Although there is a significant decline in liquefaction time in the case group but the viscosity, semen volume, and PH of semen samples were similar in the both case and control groups. Conclusion: Our results suggest that HBV and HCV infection are associated with poor sperm quality.
