Risk Factors Associated with Permanent Access-Site Infections in Chronic Hemodialysis Patients

Abstract Background Hemodialysis patients with COVID-19 have been reported to be at higher risk for death than the general population. Several prognostic factors have been identified in the studies from Asian, European or American countries. This is the first national Lebanese study assessing the factors associated with SARS-CoV-2 mortality in hemodialysis patients. Methods This is an observational study that included all chronic hemodialysis patients in Lebanon who were tested positive for SARS-CoV-2 from 31st March to 1st November 2020. Data on demographics, comorbidities, admission to hospital and outcome were collected retrospectively from the patients’ medical records. A binary logistic regression analysis was performed to assess risk factors for mortality. Results A total of 231 patients were included. Mean age was 61.46 ± 13.99 years with a sex ratio of 128 males to 103 females. Around half of the patients were diabetics, 79.2% presented with fever. A total of 115 patients were admitted to the hospital, 59% of them within the first day of diagnosis. Hypoxia was the major reason for hospitalization. Death rate was 23.8% after a median duration of 6 (IQR, 2 to 10) days. Adjusted regression analysis showed a higher risk for death among older patients (odds ratio = 1.038; 95% confidence interval: 1.013, 1.065), patients with heart failure (odds ratio = 4.42; 95% confidence interval: 2.06, 9.49), coronary artery disease (odds ratio = 3.27; 95% confidence interval: 1.69, 6.30), multimorbidities (odds ratio = 1.593; 95% confidence interval: 1.247, 2.036), fever (odds ratio = 6.66; 95% confidence interval: 1.94, 27.81), CRP above 100 mg/L (odds ratio = 4.76; 95% confidence interval: 1.48, 15.30), and pneumonia (odds ratio = 19.18; 95% confidence interval: 6.47, 56.83). Conclusions This national study identified older age, coronary artery disease, heart failure, multimorbidities, fever and pneumonia as risk factors for death in patients with COVID-19 on chronic hemodialysis. The death rate was comparable to other countries and estimated at 23.8%.

All Cause Mortality

Background and objectives: Metabolic syndrome (MetS) is a cluster of risk factors, such as abdominal obesity, insulin resistance, dyslipidemia and hypertension, that together increase the risk of cardiovascular disease. Chronic hemodialysis (HD) patients have multiple comorbidities and many metabolic disorders, causing the frequent occurrence of metabolic syndrome. The goal of this study was to assess the prevalence of MetS in HD patients, and its association with all-cause and cardiovascular (CV) mortality. Patients and methods: A total of 138 HD patients were included in this prospective study. We analyzed demographic, anthropometric and biochemical data. Outcome measures were all-cause and CV mortality during the three-year follow-up. Results: MetS was diagnosed in 57.24% of enrolled patients. During the 36 months of follow-up, 33 patients died. MetS patients showed a significantly higher mortality rate than non-MetS (30.4% versus 16.36%, p < 0.001). The association of different MetS components with cardiovascular mortality reached significance when a minimum of three components were present (1.81 (95% confidence interval CI = 1.21–2.33)), with a grouped increase in effect size for subjects with four or five MetS components. Subjects with MetS exhibited nearly twice as high risk for all-cause (hazard ratio HR = 1.99 (95%CI) = 1.42–2.97) and 2.5 times for CV (HR = 2.51 (95%CI) = 1.25–3.83) mortality compared with those without MetS, after adjustment for age, gender, and cardiovascular disease. Conclusions: The study demonstrates that MetS is widespread in HD patients. In future, the focus must be on an active screening approach, and treatment of cardiometabolic risk factors, aiming to reduce mortality.

The Impact

Abstract Background and Aims Among hemodialysis patients, peripheral arterial disease (PAD) represents an important health care burden and has been associated with high mortality. The ancle-brachial index (ABI), is a reliable and noninvasive method used to asses PAD. The aim of this study was to evaluate the prevalence of PAD in patients undergoing chronic hemodialysis and the association with inflammation and malnutrition using serum C-reactive protein (CRP) and serum albumin as biomarkers. Method The study was conducted at different hemodialysis centers in patients receiving hemodialysis three times a week. We excluded patients with atrial fibrillation or who had been recently hospitalized. The ABI has been used as a diagnostic tool for PAD and measured before a hemodialysis session. A value of ABI less than 0.9 was considered abnormal. To better estimate the impact of malnutrition and inflammation we used the serum albumin, blood lipids values and serum C-reactive protein values defined by calculating the mean of the last three measurements. Results A total of 261 ESRD patients on maintenance hemodialysis were enrolled in the study. Mean age was 56.0 (±12) years, 58% were males, and 17.6% were diabetics. Mean time on hemodialysis was 5.9 (±6.7) years, with 24% of patients on dialysis for less than 3 years. Among our patients we found that the prevalence of PAD was 23.4%, of whom 58.1% were men. We found that age, diabetes, duration of hemodialysis, low serum albumin levels and high serum triglyceride levels were risk factors for PAD in hemodialysis patients. The multivariate analysis of our study has shown that a lower level of albumin and higher level of CRP were significantly associated with an ABI less than 0.9 (odds ratio, 4.54; 95% confidence interval, P = 0.017) after adjusting for demographic, clinical, biochemical and medication data. We did not find significant differences in serum calcium, phosphate or PTH levels between patients with PAD and those without it. Conclusion In conclusion, the present study showed high prevalence of PAD in patients on hemodialysis. The prevalence was higher in diabetics. Low albumin levels and C-reactive levels were independent risk factors of PAD. We found that early diagnosis and treatment of PAD could help to improve the quality of life of hemodialysed patients and postpone arterial complications in this group of patients.
