COVID-19 patients with severe or critical symptoms are often treated with corticosteroids, per contemporary guidelines. Due to their immunosuppressive and immunomodulatory properties, corticosteroids are associated with the development of superinfections. We aimed to retrospectively assess patterns of corticosteroid use and the profiles of bacterial blood stream infections associated with exposure to different dosing levels, in a cohort of 1558 real-life adult COVID-19 patients.

Background: There are uncertainties regarding associations of prior proton pump inhibitor (PPI) use with susceptibility for COVID-19 and risks associated with SARS-CoV-2 infection. We aimed to evaluate the associations of prior PPI use with outcomes in hospitalized patients with COVID-19.

Research Design And Methods: We have retrospectively evaluated a total of 5959 consecutively hospitalized patients with COVID-19 from a tertiary-level institution in the period 3/2020-6/2021.

Antimicrobial consumption is increasing. In order to maximize the effectiveness of antimicrobial stewardship and provide safe and optimal use of restricted antimicrobial drugs, renal dosing should be evaluated. The aim of this study was to determine the prevalence of restricted antimicrobial drugs that required dose adjustment according to renal function.

Healthcare-associated infections are an emerging cause of morbidity and mortality in COVID-19 intensive care units (ICUs) worldwide, especially those caused by multidrug-resistant (MDR) pathogens. The objectives of this study were to assess the incidence of bloodstream infections (BSIs) among critically ill COVID-19 patients and to analyze the characteristics of healthcare-associated BSIs due to MDR in an COVID-19 ICU. A single-center retrospective study was conducted at a tertiary hospital during a 5-month period.

Article Synopsis
  • The study aimed to assess the effectiveness of various prognostic scores in predicting survival outcomes for hospitalized COVID-19 patients.
  • A review of 4,014 patient records showed that all scores could distinguish mortality rates, with CURB-65 and 4C Mortality Score being the most effective, particularly for predicting 30-day mortality and in-hospital mortality.
  • The results indicated that simpler scores like CURB-65 performed equally or better than more complex prognostic systems, making it a valuable tool for risk assessment in COVID-19 patients.

Aim: To evaluate the association of remdesivir use and the survival of hospitalized patients with coronavirus disease 2019 (COVID-19).

Methods: We retrospectively reviewed the medical records of 5959 COVID-19 patients admitted to our tertiary-level hospital from March 2020 to June 2021. A total of 876 remdesivir-treated patients were matched with 876 control patients in terms of age, sex, Charlson comorbidity index (CCI), WHO-defined COVID-19 severity on admission, and oxygen requirement at the time of remdesivir use.

Aim: To investigate clinical and prognostic associations of red cell distribution width (RDW) in hospitalized coronavirus disease 2019 (COVID-19) patients.

Methods: We retrospectively analyzed the records of 3941 consecutive COVID-19 patients admitted to a tertiary-level institution from March 2020 to March 2021 who had available RDW on admission.

Results: The median age was 74 years.

Aim: To evaluate the burden and predictors of thromboembolic complications in a large real-life cohort of hospitalized patients with established coronavirus disease 2019 (COVID-19).

Methods: We retrospectively reviewed the records of 4014 consecutive adult patients admitted to a tertiary-level institution because of COVID-19 from March 2020 to March 2021 for the presence of venous and arterial thrombotic events.

Results: Venous-thromboembolic (VTE) events were present in 5.

Outcomes of 109 hospitalized COVID-19 patients who received at least one vaccine dose 14 or more days prior the disease onset were retrospectively compared to control cohort of 109 age, sex, and Charlson comorbidity index-matched patients chosen among 2990 total hospitalized patients in our tertiary-level institution in a period from January to June 2021. Among 109 vaccinated patients, 84 patients were partially and 25 fully vaccinated. Vaccinated patients experienced significantly lower 30 days mortality (30% vs.

Eosinophilic esophagitis and herpes simplex esophagitis are separately well-described entities, but their simultaneous occurrence may pose a special challenge to the clinician, especially regarding the optimal therapeutic approach. The following case report describes a patient with a history of cow's milk and dairy products intolerance, but without an underlying immunologic defect, in whom eosinophilic esophagitis was diagnosed in the course of primary herpes simplex virus 1 (HSV1) infection that clinically presented as herpes labialis and severe esophagitis. The diagnosis was confirmed by a polymerase chain reaction from cytological brush and by immunohistochemical staining that detected the presence of HSV1 DNA in esophageal mucosa, and histologically by persistent eosinophil-predominant inflammation, typical of eosinophilic esophagitis.
