Large cohort studies suggest that high convective volumes associated with online hemodiafiltration may reduce the risk of mortality/morbidity compared to optimal high-flux hemodialysis. By contrast, intradialytic tolerance is not well studied. The aim of the FRENCHIE (French Convective versus Hemodialysis in Elderly) study was to compare high-flux hemodialysis and online hemodiafiltration in terms of intradialytic tolerance. In this prospective, open-label randomized controlled trial, 381 elderly chronic hemodialysis patients (over age 65) were randomly assigned in a one-to-one ratio to either high-flux hemodialysis or online hemodiafiltration. The primary outcome was intradialytic tolerance (day 30-day 120). Secondary outcomes included health-related quality of life, cardiovascular risk biomarkers, morbidity, and mortality. During the observational period for intradialytic tolerance, 85% and 84% of patients in high-flux hemodialysis and online hemodiafiltration arms, respectively, experienced at least one adverse event without significant difference between groups. As exploratory analysis, intradialytic tolerance was also studied, considering the sessions as a statistical unit according to treatment actually received. Over a total of 11,981 sessions, 2,935 were complicated by the occurrence of at least one adverse event, with a significantly lower occurrence in online hemodiafiltration with fewer episodes of intradialytic symptomatic hypotension and muscle cramps. By contrast, health-related quality of life, morbidity, and mortality were not different in both groups. An improvement in the control of metabolic bone disease biomarkers and β2-microglobulin level without change in serum albumin concentration was observed with online hemodiafiltration. Thus, overall outcomes favor online hemodiafiltration over high-flux hemodialysis in the elderly.
During a cumulated survey of 286 months, covering 11 gastroenterological patients under nocturnal-cyclic home parenteral nutrition, 24 cases of catheter-related sepsis were observed (one/11.9 months). None of these were associated with focus of infection at the cutaneous entry point or at the subcutaneous tunnel of the catheters. In this study attempt was made to control sepsis without removal of the surgically implanted siliconed lines (Vygon code 180-20 with an internal filling volume of 1 ml). The first two catheter-sepsis were conventionally treated with systemic antibiotics for 3 weeks which meant a 1-month hospital admission each time. Consequently, we used a new antibiotic therapy consisting of locking 12 hr/day 2 ml of highly concentrated antibiotic solution within the catheter. After identification of bacterial strains by blood cultures, the antibiotic lock-technique was daily applied either alone for 16 days (group I, n = 11) or for 12 days following a 3-day course of systemic antibiotics (group II, n = 11). After starting antibiotics via the infected line, the time taken for fever abatement and for obtaining negative in-line blood cultures were 2 and 4 days, respectively, and identical in group I and II. Failure of antibiotic treatment leading to catheter withdrawal was observed once in each group (9%) and was due to secondary candida catheter-sepsis. The time for hospital stay was shorter p less than 0.02 in group I (4 days) than in group II (7 days). Antibiotic-lock technique was then applied by trained patients at home.(ABSTRACT TRUNCATED AT 250 WORDS)
The aim of this study was to estimate the incidence of COVID-19 disease in the French national population of dialysis patients, their course of illness and to identify the risk factors associated with mortality. Our study included all patients on dialysis recorded in the French REIN Registry in April 2020. Clinical characteristics at last follow-up and the evolution of COVID-19 illness severity over time were recorded for diagnosed cases (either suspicious clinical symptoms, characteristic signs on the chest scan or a positive reverse transcription polymerase chain reaction) for SARS-CoV-2. A total of 1,621 infected patients were reported on the REIN registry from March 16th, 2020 to May 4th, 2020. Of these, 344 died. The prevalence of COVID-19 patients varied from less than 1% to 10% between regions. The probability of being a case was higher in males, patients with diabetes, those in need of assistance for transfer or treated at a self-care unit. Dialysis at home was associated with a lower probability of being infected as was being a smoker, a former smoker, having an active malignancy, or peripheral vascular disease. Mortality in diagnosed cases (21%) was associated with the same causes as in the general population. Higher age, hypoalbuminemia and the presence of an ischemic heart disease were statistically independently associated with a higher risk of death. Being treated at a selfcare unit was associated with a lower risk. Thus, our study showed a relatively low frequency of COVID-19 among dialysis patients contrary to what might have been assumed.
