Excessive release of cytokines during systemic inflammatory response syndrome (SIRS) often leads to refractory hypotension and multiple organ failure with high mortality. Cytokine removal with hemoadsorption has emerged as a possible adjuvant therapy, but data on interleukin-6 (IL-6) reduction and outcomes in clinical practice are scarce. We aimed to evaluate the effect of CytoSorb hemoadsorption on laboratory and clinical outcomes in shocked patients with SIRS. We designed a retrospective analysis of all patients with SIRS treated with CytoSorb in intensive care units (ICU). IL-6, laboratory and hemodynamic parameters were analyzed at approximate time intervals during CytoSorb treatment in the whole cohort and in a subgroup with septic shock. Observed and predicted mortality rates were compared. We included 118 patients with various etiologies of SIRS (septic shock 69%, post-resuscitation shock 16%, SIRS with acute pancreatitis 6%, other 9%); in all but one patient, CytoSorb was coupled with renal replacement therapy. A statistically significant decrease in IL-6 and vasopressor index with an increase in pH and mean arterial pressure was observed from 6 h onward. The reduction of lactate became significant at 48 h. Results were similar in a subgroup of patients with septic shock. Observed ICU and in-hospital mortalities were lower than predicted by Sequential Organ Failure Assessment (SOFA) (61% vs. 79%, p = 0.005) and Acute Physiology and Chronic Health Evaluation (APACHE) II (64% vs. 78%, p = 0.031) scores. To conclude, hemoadsorption in shocked patients with SIRS was associated with a rapid decrease in IL-6 and hemodynamic improvement, with improved observed vs. predicted survival. These results need to be confirmed in a randomized study.

Impaired physical mobility in hemodialysis (HD) patients is considered an important modifiable risk factor of increased all-cause morbidity and mortality. To our knowledge, no study to date has determined the overall burden of limited physical mobility in prevalent HD patients. The aim of this research is to investigate impaired physical mobility and its clinical correlates. We conducted a cross-sectional observational study in all patients of the Centre for Acute and Complicated Dialysis at the University Medical Centre of Ljubljana, where the most complex patients receive HD on average three times per week. The data were collected through interviews based on a prepared questionnaire and medical history review. A total of 205 patients were included in this study (63.9 ± 15.4 years). Sixty percent (122/205) of the patients had little or no physical mobility impairment, and others were categorized with a minor or severe mobility limitation. A minor mobility impairment was found in 21% (43/205) of patients: 10 patients (5%) used a mobility aid in the form of a crutch, 9 patients (4%) were dependent on two crutches or a walker, and 24 patients (12%) were temporarily dependent on the assistance of a third person. Severe mobility limitations were observed in 22% (40/205) of patients, ranging from being confined to bed (19/205, 9%), confined to bed but able to perform some movements (19/205, 9%), and ambulatory but dependent on the assistance of a third person for locomotion (2/205, 1%). The most common causes of the limitation of mobility were neurological (19/40, 47.5%), cardiovascular (9/40, 22.5%), musculoskeletal (8/40, 20%), and other causes (4/40, 10%). A significant, moderate positive correlation was observed between mobility problems and the age of the participants (r = 0.36, p < 0.001), while a significant, small positive correlation was obtained between the mobility problems and C-reactive protein (r = 0.15, p = 0.044). Moreover, mobility problems had a small but significant negative correlation with albumin levels (r = −0.15, p = 0.042). When controlling for age, results yield no significant correlations, and, in regression analysis, only the age (p < 0.001) and male gender (p = 0.007) of the participants were independent predictors of mobility impairment. We conclude that impaired mobility has a high overall prevalence among chronic HD patients. Strategies to prevent and improve mobility limitations are strongly needed.

Background: Pro- and anti-inflammatory cytokines help regulate the inflammatory response. A cytokine storm is a dysregulated cytokine response associated with sepsis and other conditions that result in a hyper-inflammatory state. Extracorporeal cytokine adsorption has the potential to restore a balanced inflammatory response. Hemoperfusion with CytoSorb® (CS) appears to be a short-term mode of treatment of sepsis in both adults and children. Objective: We present a case series of eight critically ill children involving the use of hemoperfusion with CS at the University Medical Center Ljubljana to treat clinically manifested cytokine storm. Results: In our preliminary experience, it was applied without complication in five children weighing more than 10 kg, who all survived. The effect of age on complications regarding CS treatment is unclear, yet in our case series, all three patients weighing less than 10 kg died of their disease. Conclusions: In our preliminary experience, cytokine adsorption with CS remains a potential adjunctive treatment for cytokine storm in critically ill children.

This study summarized the relevant literature and aimed to determine the effect of exercise-based interventions after myocardial infarction in middle-aged and older adults. Studies were identified and analyzed according to the PRISMA guidelines. The following electronic databases were used: Google Scholar, PubMed, Mendeley, Science Direct, and Scopus. The identified studies had to be longitudinal, be published in English, have taken place between 2010 and 2020, involve participants who had suffered myocardial infarction, and address different types of exercise-based interventions to be included. Of the 592 relevant studies identified, 20 were included in the qualitative analysis. After analyzing the results obtained, it could be concluded that different types of exercise-based interventions or their combination have a positive effect after myocardial infarction in middle-aged and elderly adults. It can also be suggested that the combination of a cycle ergometer and a treadmill may be the most effective exercise-based intervention. An adequate choice of intensity and volume is crucial, with the optimal duration of the experimental program and the type(s) of exercises adapted to participants after myocardial infarction.

Background. CMV seropositivity has been associated with increased epoetin demand in patients with end-stage kidney disease (ESKD) undergoing kidney replacement therapy (KRT). However, the available data remain inconclusive. Methods. In this single-center retrospective study we screened adult kidney transplant candidates with dialysis-dependent ESKD and whose CMV serostatus was known. Baseline patient characteristics and erythropoiesis-stimulating agent (ESA) prescription data were evaluated. Multivariate analysis was performed to determine whether CMV seropositivity or anti-CMV immunoglobulin levels are associated with more frequent ESA prescription and higher standardized ESA weekly dose. Results. A total of 198 patients were included, with a median age of 51 years; 31% were female. The majority of patients (73%) were treated with hemodialysis, and the median dialysis vintage was 1 year. ESA therapy was prescribed to 77% of patients, with a standardized median weekly dose of 61 units per kilogram of body weight. CMV seropositivity was identified in 79% of patients and was associated with older age, longer dialysis vintage, higher serum CRP and ferritin levels, and lower serum total iron-binding capacity. In adjusted regression models, ESA prescription rate and ESA weekly dose were not associated with CMV seropositivity. Conversely, higher ESA weekly dose was associated with CMV IgG levels in the 5th quintile (both p < 0.001) after adjustment for hemoglobin levels and body iron stores. Conclusion. CMV seropositivity was not associated with an increased likelihood of ESA prescription among transplant-listed individuals with ESKD. In a fully adjusted regression model, however, standardized weekly ESA dose was significantly higher in individuals with anti-CMV IgG levels in the highest quintile. Further studies are warranted to determine the true nature of these observations. If confirmed, it will be important to clarify whether elevated anti-CMV IgG levels reflect underlying immune dysregulation, or conversely, whether CMV reactivations contribute both to increased IgG levels and to ESA hyporesponsiveness.
