Objective It has recently been reported that some COVID-19 patients have long-term positive fecal nucleic acid after discharging from the hospital with negative nucleic acid in the respiratory tract, but it is unclear whether COVID-19 patients with positive long-term fecal nucleic acid tests have the risk of self-infection. Patients and methods From January 25, 2020 to March 9, 2020, 5 COVID-19 patients with negative respiratory tract nucleic acid and positive fecal nucleic acid were observed and studied to explore whether these patients can re-infect themselves. Five patients with COVID-19 accompanied by diarrhea as the main gastrointestinal symptoms were carefully observed through clinical symptoms, imaging and other auxiliary examinations. The RT-PCR technology was used to continuously detect fecal and respiratory viral nucleic acids. The IgM antibody was detected on the 7th day of admission and IgM/IgG at the time of discharge. Results All 5 patients had symptoms of fever and diarrhea upon admission. The fecal nucleic acid was positive, as well as the throat swab was positive. All COVID-19 patients had positive IgM antibodies on the 7th day of admission and positive IgM and IgG at the time of discharge, and there were no abnormalities in the gastrointestinal examination on discharge. All 5 fecal nucleic acid tests were positive at the time of discharge. After continuous dynamic follow-up for 3-15 days, no clinical symptoms recurred, and the last nucleic acid test was negative. GSK2879552 inhibitor Conclusions There is no risk of self-infection for COVID-19 patients with long-term 2019-nCoV nucleic acid positive in feces.Objective Coronavirus disease 2019 (COVID-19) related coagulopathy may be the first clinical manifestation even in non-vasculopathic patients and is often associated with worse clinical outcomes. Case presentation A 78 years old woman was admitted to the Emergency Unit with respiratory symptoms, confusion and cyanosis at the extremity, in particular at the nose area, hands and feet fingers. A nasal swab for COVID-19 was performed, which resulted positive, and so therapy with doxycycline, hydroxychloroquine and antiviral agents was started. At admission, the patient was hemodynamically unstable requiring circulatory support with liquids and norepinephrine; laboratory tests showed disseminated intravascular coagulation (DIC). During hospitalization, the clinical condition worsened and the cyanosis of the nose, fingers, and toes rapidly increased and became dried gangrene in three days. Subsequently, the neurological state deteriorated into a coma and the patient died. Discussion In severe cases, COVID-19 could be complicated by acute respiratory disease syndrome, septic shock, and multi-organ failure. This case report shows the quick development of dried gangrene in a non-vasculopathic patient, as a consequence of COVID-19's coagulopathy and DIC. Conclusions In our patient, COVID-19 related coagulopathy was associated with poor prognosis.Objective Hepatitis C virus (HCV) infection is a global epidemic, still highly prevalent in Europe. Given efficacy and safety of HCV therapy by Direct Antiviral Agents (DAA), World Health Organization called for actions to eliminate HCV infection. A limit is represented by access to care, mostly due to the high costs of medicines. In Italy, in 2015, the access to DAA therapy was reimbursed for patients with advanced disease, whereas in 2017 universal access was granted. The aim of this study was to analyse changes in patient recruitment trends treated with DAA with or without limitations to access to therapy. Patients and methods 165,105 patients treated with DAA in Italy from 2015 to December 2018 were analysed. Daily patient treatment rate was obtained by segmented regression of interrupted time series analysis. Results 74,199 patients with advanced disease (62% with cirrhosis) had access to the therapy during the time period from 2015 to 2017. Following the extension of reimbursement criteria, 90,906 additional patients were treated (43.2% with F0-F1 and 22.9% with F2), with an absolute reduction of 59.9% of patients with advanced disease (cirrhosis decreased to 18.5%). Segmented regression of interrupted time series analysis of daily patient treatment rate showed a progressive reduction of patients with advanced disease, offset by those with initial disease. Notably, elimination of restrictions to therapy did not change the overall treatment rate. Conclusions This study showed that a no-limit reimbursement policy for DAAs prescriptions to HCV infected individuals in Italy widened the types of treated patients, but the process towards elimination of HCV infection was not significantly changed.Objective This study aims to explore the clinical efficacy of ticagrelor combined with aspirin in patients with coronary heart disease angina pectoris and the effects on N terminal pro B type natriuretic peptide (NT-ProBNP) and creatine kinase-MB (CK-MB) levels. Patients and methods A total of 150 patients with coronary heart disease angina pectoris were prospectively analyzed in this study. These patients were admitted to Huaiyin Hospital of Huai'an City from February 2017 to February 2019. The patients were divided into control group and research group according to different treatment methods. The following indicators before and after treatment were observed therapeutic efficacy, prevalence of adverse reactions, duration and frequency of angina attack, NT-ProBNP and CK-MB levels. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of NT-ProBNP and CK-MB for the curative effect of coronary heart disease angina pectoris. Results The total effective rate in the research group was higher than that in the control group (p less then 0.05). The prevalence of adverse reactions in the research group was lower than that in the control group (p less then 0.05). The duration and frequency of seizures of the two groups after treatment were lower than those before treatment. The duration and frequency of seizures in the research group were lower than those in the control group (p less then 0.05). The physiological function, physical pain, vital energy score and general health status in the research group were higher than those in the control group (p less then 0.05). The NT-ProBNP and CK-MB levels in both groups after treatment were decreased. Conclusion Ticagrelor combined with aspirin has definite therapeutic effect on patients with coronary heart disease angina pectoris, with low prevalence of adverse reactions. It can significantly reduce the levels of NT-ProBNP and CK-MB, which is worthy of promotion.
