Introduction Coronavirus 2 disease is associated with increased mortality and morbidity in chronic hemodialysis patients Methods A retrospective, observational case–control pilot study was conducted on consecutive hemodialysis outpatients (cases) and control group of individuals with preserved renal function. Complete SARS-CoV-2 vaccination with BNT162b2 mRNA vaccine, followed by determination of serum antibodies after the second dose, were required from participants in both groups. Previous COVID-19 was an exclusion criterium. Results 21 hemodialysis patients (M:F = 13:8, mean age 67.5 ± 13.4) and 16 controls without chronic kidney disease (M:F = 4:12, mean age 46.8 ± 12.7) were included. Hemodialysis patients had lower mean titers of serum antibodies to the SARS-CoV-2 spike antigen compared with controls (492.39 vs 1901.20 IU/mL, respectively; p < 0.001), a finding that was confirmed in the age-matched analysis on 18 participants (580.8 vs 1836.4 IU/mL, p = 0.006). Conclusions This study supports the finding of hyporesponsiveness to mRNA vaccination among hemodialysis patients.

Background: Chronic renal failure is a chronic medical condition characterized by a progressive and irreversible loss of kidney function. Up to 50% of patients undergoing dialysis experience symptoms of depression and anxiety: what is the impact of individual factors and medical conditions on the mental health issue? The present study was carried out to investigate the individual factors (biomarkers and psychological dimensions) of end-stage renal disease patients dealing with dialysis, analyzing their predictor values for developing negative disease adaptations by an allostatic paradigm. Methods: We conducted an observational study on 35 patients affected by end-stage renal disease; biological and psychological markers have been detected. We conducted descriptive statistical analyses (t-tests) and performed a hierarchical regression analysis to investigate the relationship between pathological medical conditions and psychological dimensions. Results: The findings showed a positive correlation between creatinine levels and psychological distress as well as stress index. No significant effect of “time of dialysis”, “time from diagnosis”, “age” and “personality traits” was found. Conclusion: Our findings showed that personality traits did not represent a protective factor by moderating positive emotional adaptations; conversely, creatinine levels appeared predictive for negative emotional adaptations. High levels of creatinine were found to be positively associated with high stress levels as well psychological distress. According to the allostatic paradigm, end-stage renal disease patients could experience an allostatic load and more overload towards poor health outcomes; integrated biological and psychological measurements could prevent increased negative mental health through a patient-centered approach.

Introduction Acute liver failure (ALF) is a rare syndrome defined by the rapid loss of liver function in the absence of pre‐existing liver disease, which may be secondary to hepatitis A virus, hepatitis E virus (HEV), or to drugs in about 50% of cases. Extracorporeal albumin dialysis enables the elimination of albumin‐bound toxins that accumulate in liver failure. Methods We report a case of ALF secondary to HEV associated with severe hyperbilirubinemia. Patient was treated with four consecutive sessions of single‐pass albumin dialysis (SPAD) carried out setting the following parameters: time: 300 min, Qb: 60 mL/min, Qd: 800–1000 mL/min, dialysate containing 4% albumin, citrate: 3–4 mmol/L. Result SPAD documented good support of liver function. Bilirubin levels were reduced from 22 to 14 g/dL after four treatments. Pruritus was the first clinical sign of improvement. Conclusion SPAD system can represent a safe and effective therapeutic option.

Acute and acute-on-chronic liver failure is a cause of death in patients suffering from viral hepatitis, and many cases need liver transplantation. Infection from hepatitis B virus may range from asymptomatic to severe acute and fulminant hepatitis. In this setting, treatment is mainly supportive as there is no consensus on antiviral therapy based on non-nucleoside reverse transcriptase inhibitors. Single-pass albumin dialysis is a liver-support technique for patients suffering from liver failure, that has shown effectiveness in the removal of both water-soluble and albumin-bound toxins, which accumulate due to impairment of the liver’s cleansing function. We report here the case of a 62-year-old male who presented with a severe acute hepatitis B infection, liver failure, and marked hyperbilirubinemia. Treatment with single-pass albumin dialysis combined with a hemoperfusion device was successful in improving clinical, physiological, and laboratory parameters.
