Patients with systemic autoimmune rheumatic disease (SARD) have increased susceptibility to viral infections, including SARS-CoV-2. The aim of this study was to analyse the SARD patient population with COVID-19 (coronavirus disease 2019) in terms of baseline characteristics, severity, course and outcomes of the disease compared with the non-SARD group, and to identify factors associated with prognosis, including remdesivir therapy efficacy. Retrospective study comprised 8220 COVID-19 cases from the SARSTer database, including 185 with SARD. Length of hospitalisation, duration of oxygen therapy, mortality and the need for HFNO (high-flow nasal oxygen) and/or NIV (noninvasive ventilation) were significantly higher in the SARD versus non-SARD group. There was no difference in clinical features on admission to hospital. Patients with SARD were older and more likely to have cardiovascular, pulmonary and chronic kidney diseases. Age, the presence of cardiovascular disease, more severe conditions on admission and higher inflammatory marker values were found to be risk factors for death in the SARD group. In patients with SARD treated with remdesivir, there was a trend towards improved mortality but without statistical significance. Length of hospitalisation, 28-day mortality and the need for HFNO and/or NIV were higher in the SARD group. These patients often had other chronic diseases and were older.

BACKGROUND The COVID-19 pandemic has sped up the implementation of telehealth solutions in medicine. A few symptom checkers dedicated for COVID-19 have been described, but it remains unclear whether and how they can affect patients and health systems. OBJECTIVE This paper demonstrates our experiences with the COVID-19 risk assessment (CRA) tool. We tried to determine who the user of the web-based COVID-19 triage app is and compare this group with patients in the infectious diseases ward’s admission room to evaluate who could benefit from implementing the COVID-19 online symptom checker as a remote triage solution. METHODS We analyzed the answers of 248,862 people interacting with an online World Health Organization–based triage tool for assessing the probability of SARS-CoV-2 infection. These users filled in an online questionnaire between April 7 and August 6, 2020. Based on the presented symptoms, risk factors, and demographics, the tool assessed whether the user’s answers were suggestive of COVID-19 and recommended appropriate action. Subsequently, we compared the sociodemographic and clinical characteristics of tool users with patients admitted to the Infectious Diseases Admission Room of J. Gromkowski Hospital in Wrocław. RESULTS The CRA tool tended to be used by asymptomatic or oligosymptomatic individuals (171,226 [68.80%] of all users). Most users were young (162,432 [65.27%] were below 40 years of age) and without comorbidities. Only 77,645 (31.20%) of the self-assessment app users were suspected of COVID-19 based on their reported symptoms. On the contrary, most admission room patients were symptomatic—symptoms such as fever, cough, and dyspnea were prevalent in both COVID-19-positive and COVID-19-negative patients. COVID-19-suspected patients in the CRA tool group presented similar COVID-19 symptoms as those who presented to the admission room. These were cough (25,062/40,007 [62.64%] in the CRA tool group vs 138/232 [59.48%] in the admission room group), fever (23,123/40,007 [57.80%] in the CRA tool group vs 146/232 [62.93%] in the admission room group), and shortness of breath (15,157/40,007 [37.89%] in the CRA tool group vs 87/232 [37.50%] in the admission room group). CONCLUSIONS The comparison between the symptomatology of the users interacting with the CRA tool and those visiting the admission room revealed 2 major patient groups who could have benefited from the implementation of the self-assessment app in preclinical triage settings. The primary users of the CRA tool were young, oligosymptomatic individuals looking for screening for COVID-19 and reassurance early in the COVID-19 pandemic. The other group were users presenting the typical symptoms suggestive of COVID-19 at that time. The CRA tool recognized these individuals as potentially COVID-19 positive and directed them to the proper level of care. These use cases fulfil the idea of preclinical triage; however, the accuracy and influence on health care must be examined in the clinical setting.

Background: Patients with kidney failure are at an increased risk of progression to a severe form of coronavirus disease 2019 (COVID-19) with high mortality. The current analysis was aimed to assess the impact of renal failure on the severity of COVID-19 and identify the risk factors of the fatal outcome in this population. Methods: The analysis included patients from the SARSTer database, a national real-world study evaluating treatment for COVID-19 in 30 Polish centers. Data were completed retrospectively and submitted online. Results: A total of 2322 patients were included in the analysis. Kidney failure was diagnosed in 455 individuals (19.65%), of whom 373 presented moderate stage and 82 patients, including 14 dialysis individuals, presented severe renal failure. Patients with kidney failure were significantly older and demonstrated a more severe course of COVID-19. The age, baseline SpO2, the ordinal scale of 4 and 5, neutrophil and platelet count, estimated glomerular filtration rate, and C-reactive protein concentration as well as malignancy and arterial hypertension were the independent predictors of 28-day mortality in logistic regression analysis. Conclusions: Underlying kidney disease in patients with COVID-19 is among the leading factors associated with a higher risk of severe clinical presentation and increased mortality rate.

BackgroundRemdesivir (RDV) is the only antiviral drug registered currently for treatment of COVID-19 after a few clinical trials with controversial results. The purpose of this study was to evaluate the effectiveness and safety of RDV in patients with COVID-19 in real world settings.MethodsPatients were selected from 1496 individuals included in the SARSTer national database; 122 of them received therapy with RDV and 211 were treated with lopinavir/ritonavir (LPV/r)-based therapy. The primary end-point of effectiveness was clinical improvement in the ordinal 8-point scale, which was defined as a 2-point decrease from baseline to 7, 14, 21 and 28 days of hospitalization. The secondary end-points of effectiveness included: death rate, rate of no clinical improvement within 28 days of hospitalization in the ordinal scale, rate of the need for constant oxygen therapy, duration of oxygen therapy, rate of the need for mechanical ventilation, total hospitalization time, and rate of positive RT PCR for SARS-CoV-2 after 30 days.FindingsSignificantly higher rates of clinical improvement, by 15% and 10% respectively, were observed after RDV treatment compared to LPV/r at days 21 and 28. The difference between regimens increased with worsening of oxygen saturation (SpO2) and depending on the baseline score from the ordinal scale. Statistically significant differences supporting RDV were also noted regarding the rate of no clinical improvement within 28 days of hospitalization and hospitalization duration in patients with baseline SpO2 ≤90%. In the logistic regression model only the administration of remdesivir was independently associated with at least a 2-point improvement in the ordinal scale between baseline and day 21.InterpretationIn conclusion, data collected in this retrospective, observational, real world study supported use of remdesivir for treatment of SARS-CoV-2 infection particularly in patients with oxygen saturation ≤95%.

Chronic hepatitis B virus (HBV) infection and HBV-related liver disease are estimated to affect about 240 million people worldwide. Now that a vaccine is available, the number of new HBV infection cases has plummeted. Yet, there are still regions with very high incidence of HBV. Hepatocellular carcinoma (HCC) is the fourth to six most common malignancy in men and the ninth most common malignancy in women worldwide. 54% of all HCC cases are HBV-associated, making it the most common cause of cancer worldwide. Hepatitis B therapy prevents progression of chronic hepatitis to cirrhosis and HCC development, but even with the best HBV treatment, such patients are still at risk of HCC. Also in patients after transarterial chemoembolization (TACE), liver resection (hepatectomy) or liver transplant, suppression of hepatitis B virus (HBV) improves patient survival. In this paper we present current possibilities of HCC and HBV treatment, which lead to improved survival and quality of life.

Spontaneous bacterial peritonitis (SBP) is one of the most common bacterial infections in patients with liver cirrhosis and it significantly contributes to the deterioration of the prognosis and increased risk of mortality. Previous data suggested that the most common pathogens causing SBP are G-negative aerobic bacteria and treatment recommended by the international guidelines (EASL, AASLD) is highly effective. In recent years, due to the widespread use of antibiotic prophylaxis and the increased frequency of hospitalization along with the use of invasive procedures in patients with cirrhosis, the involvement of Gram-positive cocci and multi-drug resistant bacteria in the etiology of SBP is increasing. This is related to the lowering of the effectiveness of the first-line therapy used so far and worsening of the prognosis, increasing in-hospital mortality. In this work we summarize current data on the characteristics of pathogens responsible for SBP in the context of currently recommended treatment regimens.

Aim of the study To determine the influence of HBsAg and HBeAg negative but anti-HBc positive status on the sustained virological response (SVR) rate in HCV-infected patients treated with pegylated interferon alfa 2 (Peg-IFNα-2) and ribavirin (RBV). Material and methods The study was based on the retrospective analysis of medical records of HCV-infected patients who started Peg-IFNα and RBV treatment between 1 January 2011 and 31 December 2013 at the 1st and 2nd Department of Infectious Diseases of the Regional Hospital in Wroclaw, Poland. Results Among 240 patients included in the analysis 99 were anti-HBc positive and 141 anti-HBc negative. In the genotype 1, anti-HBc positive group the SVR rate was 47% and in the anti-HBc negative group it was 42.7% (p = 0.591). In the genotype 3, anti-HBc positive group the SVR rate was 60% and in anti-HBc negative patients it was 63.2% (p = 0.79). Differences in SVR rates between anti-HBc positive and negative groups were not statistically significant. None of the anti-HBc positive patients developed reactivation of HBV infection during or in the 24 weeks following the end of treatment. Conclusions Anti-HBc determination does not seem to be useful in predicting treatment outcome of conventional Peg-IFNα/RBV therapy in patients infected with HCV genotypes 1 and 3.

Because the optimal treatment for COVID-19 is still unknown, it is important to explore every potential way of improving the chances of survival for COVID-19 patients. The aim of the study was to analyze the effectiveness of convalescent plasma on COVID-19 patients. The study population consisted of 78 patients diagnosed with COVID-19, selected from the SARSTer national database, who received convalescent plasma. The impact on clinical and laboratory parameters was assessed. A clinical improvement was observed in 62 (79%) patients, and 10 (13%) patients died from COVID-19. No side effects of the convalescent plasma treatment were observed. When plasma was administered earlier than 7 days from diagnosis, the total hospitalization time was shorter (p &lt, 0.05). Plasma efficacy was inferior to remdesivir in endpoints such as the necessity and duration of oxygen therapy, the duration of hospitalization, and mortality rate, and inferior to other drugs in the case of the duration of hospitalization and the necessity of constant oxygen therapy, but comparable in most other measured endpoints. A comparison of a 30-day mortality rate in patients who received plasma and remdesivir (4/25, 16%) and who received only plasma (6/53, 11%) showed no significant difference. Convalescent plasma efficacy is inferior to remdesivir when treating COVID-19 patients but the addition of remdesivir to plasma does not improve the treatment effectiveness. In most endpoints, plasma was comparable to other treatment options. In our opinion, convalescent plasma may be used as a supportive treatment in COVID-19 patients because of the low frequency of adverse effects and availability, but must be given as early from the diagnosis as possible.

We are presenting the case study of the patient diagnosed at the age of 37 with liver cirrhosis due to genotype 1b hepatitis C virus infection. At the age of 46, he was diagnosed with hepatocellular carcinoma with subsequent resection of the tumour in May 2015. In December 2015, the treatment was started with ombitasvir, paritaprevir/ritonavir and dasabuvir (3D) with ribavirin (RBV) 1000 mg per day. After 24 days of this treatment, the patient received a deceased donor liver transplantation, followed by 18-day interruption of 3D therapy. Due to the anaemia, RBV dose was reduced to 600 mg per day for the rest of the treatment. At the 11th week of 3D+RBV treatment, there was another 8-day long discontinuation of therapy due to the postoperative wound infection. In total, the patient received 24 weeks of 3D+RBV treatment, achieving sustained virological response at week 24 post-treatment.

INTRODUCTION Chronic kidney disease (CKD) is one of the consequences of human immunodeficiency virus-1 (HIV-1) infection. The disease increases the risk of progression to acquired immunodeficiency syndrome and death and complicates antiretroviral therapy. The prevalence of CKD in HIV-1-infected patients is difficult to estimate and depends on the diagnostic criteria for CKD. OBJECTIVES The aim of the study was to evaluate the usefulness of a single measurement of serum asymmetric dimethylarginine (ADMA) levels in the diagnosis of kidney damage in patients infected with HIV-1. PATIENTS AND METHODS The study included 119 HIV-1-infected individuals (88 males [74%]), both on antiretroviral treatment and treatment-naive, with a negative history of kidney disease, and 31 healthy volunteers. We analyzed demographic characteristics as well as data on concomitant diseases, antiretroviral regimen, serum ADMA concentrations, parameters of renal function, CD4+ cell count, and HIV-1 viral load. RESULTS No significant impairment of renal function was observed. Mean serum ADMA levels in all HIV-1-infected patients, as well as in treatment-naive patients and treated patients, were significantly higher (P
