Quality of life of patients with end-stage renal disease in Guinea

This questionnaire-based study included 69 patients from the Republic of Guinea with end-stage renal disease (ESRD) and was conducted over 12 months. The factors that affected their quality of life (QoL) were determined. The included ESRD patients had an estimated creatinine clearance (CCr) of <15 mL/minute using MDRD formula. We used the SF36 question-naire and classified the results into two groups: Scores <50/100 as poor QoL and scores 50/100 as good QoL. Factors that determined the QoL were cessation of all activities and additional effort required, severe or mild pain, good or bad health, and reduced or not reduced social and physical activities. Of the 69 patients, 32 (46.3%) had a good QoL and 37 (53.7%) had a poor QoL. The estimated CCr was similar in both groups. The average age of the poor QoL group was 54 ± 4 years, the good-QoL group′s average age was of 47.6 ± 4 years (P = 0.01). Patients with a good QoL had better overall health, but this was not statistically significant [OR = 0.42 (0.14-1.28); P = 0.14]. Patients with a poor QoL had more severe pain (P = 0.002); however, good QoL did not protect against mental problems [OR = 46.67 (8.18-351.97); P = 0.0001]. Mental status (P = 0.01) and social activities (P = 0.001) were reduced, and there were more comorbidities in the poor-QoL group (29.7%, with >4, P = 0.01). Good QoL was associated with younger age, fewer comorbidities, less severe physical pain, and fewer physical or social limitations. QoL could be increased by improving comorbidity treatments, giving more effective pain control, and providing more assistance for social and physical limitations

Low incidence of SARS-CoV-2, risk factors of mortality and the course of illness in the French national cohort of dialysis patients

International audienceThe 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
