Background and Objectives: Hepatitis C virus (HCV) infection is a major global public health concern, particularly in hemodialysis (HD) patients. This study aims to evaluate the demographic, clinical, and laboratory characteristics of HCV-positive patients undergoing HD and assess the long-term impact of direct-acting antivirals (DAAs) on patient outcomes. Moreover, a narrative review aims to summarize the current knowledge regarding HCV treatment in HD patients. The search in the PubMed, Google Scholar, and Scopus databases identified 48 studies relevant to our topic, 18 regarding clinical history and 29 related to HCV treatment. Methods: A retrospective analysis was performed on 165 HD patients from Bihor County HD centers, Romania, between 2014 and 2024. The cohort was divided into two groups: 54 patients who tested positive for HCV and 111 controls who were HCV-negative. Data collected from GPs included demographic information, comorbidities, laboratory parameters, and psychological assessments. Outcomes were evaluated at over 5 years after DAA treatment. A literature review was conducted using PubMed and Google Scholar to identify relevant studies on HCV in HD patients from 1989 to 2024. Results: Laboratory results showed similar parameters across groups, except for lower serum cholesterol levels in the HCV-positive DAA-treated group vs. HCV-positive non-treated ones (155.607 mg% vs. 170.174 mg%, p = 0.040) and increased ALT levels when comparing the same groups (29.107 vs. 22.261, p = 0.027), whereas comorbidities did not differ significantly. The incidence of malignancies was significantly higher among HCV-positive compared to HCV-negative patients (20.3% vs. 8.1%, p = 0.023), mainly among those treated with DAAs, highlighted by the multivariate analysis. Cardiovascular disease remains the leading cause of mortality regardless of HCV status or the use of antiviral therapy. Psychological assessments revealed more severe depression in HCV-positive patients compared to their HCV-negative counterparts. Conclusions: HCV infection in the hemodialysis population typically follows a subclinical course. At over five years after DAA therapy, the results indicate a stabilization of the liver function and the absence of major complications. However, the incidence of malignancies remains high in HCV-positive patients.

Background: Hemodialysis (HD) patients are a highly vulnerable population with elevated mortality driven by comorbidities and dialysis-specific factors. While most studies focused on intra-pandemic outcomes, long-term effects remain underexplored. We aimed to evaluate 5-year mortality and the impact of COVID-19 vaccination in chronic HD patients. Methods: A retrospective study was conducted on 211 HD patients monitored between 2020 and 2024. Outcomes included overall and cardiovascular mortality, risk factors in COVID-19-positive patients, and vaccination impact. Logistic regression identified independent predictors. Results: The cohort had a mean age of 65.6 ± 13.3 years, with 55.9% males and mean dialysis vintage of 6.9 ± 5.5 years. Overall mortality reached 53.6%, while 38.4% were vaccinated. Predictors of all-cause mortality included age (OR = 1.078, p < 0.001), BMI (OR = 0.868, p < 0.001), hemoglobin (OR = 0.581, p < 0.001), phosphorus (OR = 1.351, p = 0.025), dialysis adequacy (OR = 0.138, p = 0.013), and ischemic cardiopathy (OR = 0.327, p = 0.009). In COVID-19-positive patients, mortality was associated with age (OR = 1.069, p = 0.002), low hemoglobin (OR = 0.642, p = 0.014), BMI (OR = 0.885, p = 0.009), CRP (OR = 1.015, p < 0.001), and coronary artery disease (OR = 5.68, p < 0.001). Cardiovascular disease was the leading cause of death (44.6% in COVID-19-positive vs. 73.3% in negatives, p = 0.006). Vaccination significantly reduced COVID-19-related mortality (OR = 0.023, p = 0.005) but did not influence overall or non-COVID mortality. Conclusions: Five-year mortality in HD patients remained high, mainly cardiovascular, and was strongly influenced by age, BMI, hemoglobin, dialysis adequacy, and comorbidities. COVID-19 vaccination substantially reduced COVID-related mortality but did not alter all-cause outcomes. These findings support vaccination and careful risk stratification in HD populations for future pandemics.

Background and Objectives: Hemodialysis (HD) patients represented a highly vulnerable population during the COVID-19 pandemic, both clinically and psychologically. Data regarding acute anxiety requiring pharmacologic treatment in this setting are limited. The aim of the study was to assess factors influencing clinical evolution, psycho-emotional disturbances reflected by “de novo” anxiolytic use, and vital prognosis of hospitalized COVID-19 patients on HD. Materials and Methods: The study included 211 patients followed between 2020 and 2023 (149 were COVID-19 positive and 80 required hospitalization) and comprised two sequential phases: an in-hospital phase during COVID-19, in which disease severity factors, in-hospital mortality, and the requirement for de novo anxiolytic therapy were assessed, and a follow-up phase, which evaluated overall mortality and the impact of vaccination on long-term outcomes. Results. Hospitalized patients were older, had lower dialysis adequacy, and a lower rate of COVID-19 vaccination. Severe COVID-19, associated with elevated inflammatory markers, prolonged hospitalization, and an increased need for anxiolytic therapy to control acute psychopathological disturbances, was significantly more frequent in patients with underlying oncological comorbidities. Patients who died from COVID-19 during hospitalization were older (69.364 ± 1.973 vs. 66.426 ± 1.546, p = 0.239), predominantly male (66.69% vs. 48.93%, p = 0.064), had similar BMI (26.836 ± 1.120 vs. 26.909 ± 0.943, p = 0.961), and had shorter duration on HD (5.182 ± 4.733 vs. 7.383 ± 6.060, p = 0.085). Patients who received anxiolytic therapy during hospitalization for COVID-19 were younger, predominantly male, and had a longer dialysis vintage as well as a higher body mass index. Although the de novo need for anxiolytics during COVID hospitalization was associated with multiple parameters in the linear regression analysis, the multivariable regression model showed a significant and strong association only with corticosteroid therapy (OR = 16.403, 95% CI = 4.433–62.111, p < 0.001). COVID-19 vaccination was associated with a significant reduction in mortality risk, with vaccinated patients exhibiting a 58% lower hazard of death compared with unvaccinated individuals (HR = 0.42; 95% CI: 0.28–0.62; p < 0.001). Conclusions: COVID-19 in HD patients is a multidimensional pathology, in which clinical severity and preventive strategies, such as vaccination, significantly influence survival. Acute anxiety requiring pharmacologic intervention was highly prevalent in hospitalized HD patients with COVID-19, but was not associated with worse survival (p = 0.903). Psychological burden should be recognized as an important component of care in this population.
