Serum fetuin-A levels showed a negative correlation with E/E' (r = -0.299, P = 0.009). Fetuin-A levels were considered an independent predictor of diastolic dysfunction.

A decrease in the serum fetuin-A level is associated with an increased risk of LVDD in patients on haemodialysis.

Coronavirus disease 2019 (COVID-19) causes a wide spectrum of symptoms, from asymptomatic conditions to severe inflammatory response. Hemodialysis (HD) patients have a higher risk for developing severe COVID-19 because of older age, multiple co-morbid conditions, and impaired immune system compared to the general population. As little is known about these special groups, we evaluated the clinical characteristics and outcomes of HD patients with COVID-19.

All hospitalized HD patients with COVID 19 between March 11, 2020 and May 31, 2020 were included in the study. The composite end-points consisted of admission to the intensive care unit (ICU), discharging or death were analysed. Demographic, clinical, laboratory, and treatment data were retrieved and compared between survivors and nonsurvivors.

A total of 45 patients (median age 65.33 ± 12.22, 24 female, 53.96 ± 40.68) were enrolled and of whom 14 were admitted to ICU and overall 14 (31.1%) have died. Hypertension was the most common comorbidity and fever (60%), dyspnea (55.6%) and cough (53.3%) were predominant symptoms at admission. 8.8% of patients developed severe complications (acute respiratory distress syndrome, macrophage activation syndrome) and secondary infection was observed in 51.1% of the patients. Elevation in the level of inflammatory markers, lactate dehydrogenase, liver enzymes, troponin, creatine kinase, and decrease in lymphocyte count and serum albumin level were observed in non-survivors compared with survivors throughout the clinical course. No significant difference was observed in the score of chest CT performed on the day of hospitalization for the survivors and non-survivors.

Mortality of COVID-19 in HD patients is high and follow up of certain laboratory parameters can help to predict the prognosis of the patients.

Acute kidney injury (AKI), secondary to renal ischemia/reperfusion (I/R), is a serious problem associated with high mortality. learn more The pathophysiology of AKI after renal I/R involves peroxynitrite production; hence, scavenging this metabolite may rescue AKI. Entacapone is a catechol-O-methyl transferase (COMT) inhibitor which elicits antioxidant activity by scavenging peroxynitrite. Therefore, we hypothesized that the peroxynitrite scavenging activity of entacopone protects against AKI after renal I/R injury in rats.

Male Wistar rats were given either entacapone or a well-known peroxynitrite scavenger (FeTPPS) daily for 10days before I/R procedures. I/R was induced by occluding both renal pedicles for 45min followed by reperfusion for 24h.

Pre-treatment with either entacapone or FeTPPS improved renal function as indicated by a significant reduction in serum creatinine and urea when compared to I/R group (P < 0.05). I/R injury increased renal levels of NO (4-folds, P < 0.05), iNOS (4-folds, P < 0.05), and 3-nitrotyrosine (5-folds, P < 0.05) compared to sham control. These effects were abrogated in animals pre-treated with entacapone or FeTPPS before being subjected to I/R (P < 0.05). In addition, entacapone or FeTPPS significantly inhibited I/R-induced elevation in renal TNF-α levels (78% and 58%, respectively) and caspase-3 activity (72% and 56%, respectively) indicating the reduction of both inflammation and apoptosis in the kidney (P < 0.05). The two drugs also improved kidney and liver functions in rats with renal I/R injury.

Our study showed that entacapone and FeTPPS protected against AKI and remote liver damage associated with renal I/R and this effect might be due to scavenging peroxynitrite and reducing nitrosative stress.

Early peritoneal dialysis catheter (PDC)-related complications are frequent and make an important contribution to long-term PD survival. We aimed to analyse the incidence and specific causes of early PDC-related complications.

This study was conducted from January 2001 to December 2012, utilising the New Zealand PD Registry (NZPDR) data. The objectives of this study were to analyse the incidence and causes of PDC-related complications within 4weeks and 3months of insertion. A logistic regression analysis was conducted to analyse any demographic or clinical risk factors of early PDC-related complications.

Of the 2573 PDC insertions during this period, majority 88% were surgically inserted. The number of complication within 4weeks ranged from minimum of 20% to a maximum of 34% annually, with infections and flow dysfunctions leading the causes. There has been a minor drop in the infection rates from 19 to 16% (p = 0.21), and flow dysfunction from 12 to 9% (p = 0.16), from 2001 to 2012. A reduced odds of ea 2001 to 2012. A reduced odds of early complication was noted in elderly individuals above 60 years age, with odds ratio of (OR) of 0.73 (95% CI 0.53-0.99), while as higher odds of early complications were recorded in female gender, OR 1.41 (95% CI 1.06-1.88). Of the 10% of patients who failed to initiate PD within 90 days, flow dysfunction contributed to 32%, followed by infectious and surgical causes in 16% and 15%, respectively. The median time from insertion of PDC to initiation of PD was 17 days (interquartile range of 14-24 days) CONCLUSIONS Improvements in PDC insertion techniques and reduction in infection rates may result in improvements in long-term PD technique survival.
Influenza and pneumococcal vaccination rates among peritoneal dialysis (PD) patients remain suboptimal, despite availability of vaccinations and health recommendations.

The primary aim was to improve influenza and pneumococcal vaccination rates among incident PD patients at our center to 80%. A secondary aim was to develop a sustainable workflow for vaccination in PD patients.

A quality improvement (QI) initiative to increase vaccination rate among incident PD patients was conducted in a tertiary care hospital in Singapore from Jul 2017 to Dec 2018. Key drivers and barriers to success were identified through root cause analysis. Change ideas focusing on improving opportunities, access and enhancement of reminder systems were implemented using Plan-Do-Study-Act methodology. Vaccination rates were monitored at 3-month intervals.

Total of 249 patients were eligible for vaccination. The baseline vaccination rate for influenza, pneumococcal conjugate vaccine (PCV13) and pneumococcal polysaccharide vaccine (PPSV23) were 63%, 54% and 14%, respectively.
