    Health-related quality of life and adequacy of dialysis for the individual maintained on peritoneal dialysis
    SAGE Publications ; 2020

    Abstract: The goal of care of the peritoneal dialysis (PD) patient should be directed at adjusting therapy to maximize the patient’s health-related quality of life (HRQOL). Incorporating the routine assessments of HRQOL into the care of PD patients is important and should serve as an essential marker of the adequacy of dialysis and help the dialysis staff design the optimal treatment regimen for each patient. HRQOL is best assessed with patient-reported outcome measures (PROMs). How best to incorporate these PROMs into the routine care of the PD patient is not clear in terms of the best instruments to use, frequency of measurements, patient acceptability, and how to translate these assessments into improvements in patient care. Nevertheless, incorporating routine assessments of HRQOL into the care of PD patients is essential if the dialysis team is to provide optimal care; it is an area that is receiving increasing attention and is ripe for further study and investigation.

    Abstract: Regeneration of peritoneal dialysis (PD) fluid using sorbent technology can provide flexibility and improve quality of life. This study examined the safety and efficacy of the automated wearable artificial kidney (AWAK) device in PD patients. Methods: This pilot study included prevalent PD patients from a single center in Singapore between 2016 and 2018. Participants underwent up to nine AWAK therapies over 72 h and were followed up for 1 month. Primary outcomes were serious adverse events (SAEs) and completion of nine therapies without device deficiency. Secondary outcomes were weekly peritoneal Kt/ V urea , solutes clearance and adverse events (AEs). Results: Twenty-one patients were screened and 15 were included in the study. Device alterations were required to overcome issues including flow occlusions initially, which resulted in three cohorts ( n = 2, 2 and 11 respectively). No SAEs were observed during the study and at the follow-ups. Common AEs were abdominal pain/discomfort (60%) and bloatedness (47%). The median estimated peritoneal weekly Kt/ V urea was 3.0 (interquartile range: 2.2–4.8). There were significant reductions in pre- and post-study median serum urea (20.8 vs. 14.9 mmol/L; p = 0.001), creatinine (976.0 vs. 667.5 µmol/L; p = 0.001), phosphate (1.7 vs. 1.5 mmol/L; p = 0.03), and β2-microglobulin (29114.0 vs. 26339.0 µg/L; p = 0.048). Fluid reabsorption occurred among patients with residual kidney function. However, median body weights were not significantly different pre- and post-study (66.4 vs. 65.7 kg; p = 0.83). Conclusions: This preliminary study demonstrated that no SAEs were observed with the AWAK-PD device; however, 60% of participants developed abdominal pain/discomfort. Further device enhancements are needed to improve ultrafiltration and reduce AEs.

    Outcomes following peritoneal dialysis catheter removal with reinsertion or permanent transfer to haemodialysis
    SAGE Publications ; 2019

    Abstract: Long-term use of peritoneal dialysis catheter is associated with complications such as infection and malfunction, necessitating removal of catheter with subsequent reinsertion or permanent transfer to haemodialysis. This study aims to investigate the outcome in patients who underwent reinsertion. Methods and materials: A single-centre retrospective study was performed in Singapore General Hospital for all adult incident peritoneal dialysis patients between January 2011 and January 2016. Study data were retrieved from patient electronic medical records up till 1 January 2017. Results: A total of 470 patients had peritoneal dialysis catheter insertion with median follow-up period of 29.2 (interquartile range = 16.7–49.7) months. A total of 92 patients required catheter removal. Thirty-six (39%) patients underwent catheter reinsertion. The overall technique survival at 3 and 12 months were 83% and 67%. Median time to technique failure of the second catheter was 6.74 (interquartile range = 0–50.2) months. The mean survival for patients who converted to haemodialysis and re-attempted peritoneal dialysis was comparable (54.9 ± 5.5 vs 57.3 ± 3.6 months; p = 0.75). Twelve (13%) patients had contraindication for peritoneal dialysis and were excluded from analysis. Of 11 patients who required catheter removal due to malfunction, 7 (64%) underwent catheter reinsertion and 6 (86%) patients ultimately converted to haemodialysis during study period. Of the 69 patients who had catheter removal due to infection, 29 (42%) underwent catheter reinsertion and 8 (28%) patients eventually converted to haemodialysis during the study period. Conclusion: Patient survival was comparable between patients who re-attempted peritoneal dialysis and patients who transferred to haemodialysis. Patients who had previous catheter removal due to infections had favourable technique survival than those due to catheter malfunction.

    Genomics and Disease Progression in IgA Nephritis
    Academy of Medicine, Singapore ; 2013

    Abstract: Apart from clinical, histological and biochemical indices, genomics are now being employed to unravel the pathogenetic mechanisms in the disease progression of IgA nephritis (IgAN). The results of angiotensin converting enzyme (ACE) gene polymorphism have been controversial. Those patients with the DD genotype seem to have a poorer prognosis. However, with high dose angiotensin receptor blocker (ARB) therapy, the ACE gene polymorphism status of a patient may no longer be a matter for concern as those with the DD genotype would also respond favourably to high dose ARB therapy. Association studies with gene sequencing and haplotypes have suggested that multiple genes are involved in the pathogenesis of IgAN. Some workers have reported a synergistic effect in the combined analysis of AGT-M235T and ACE I/D polymorphism. With the use of deoxyribo nucleic acid (DNA) microarray, tens of thousands of gene expressions genome-wide can be examined together simultaneously. A locus of familial IgAN has been described with strong evidence of linkage to IgAN1 on chromosome 6q22-23. Two other loci were reported at 4q26-31 and 17q12-22. DNA microarray techniques could also help in the identification of specific pathogenic genes that are up- or down-regulated and this may allow genome wide analyses of these genes and their role in the pathogenesis and progression of IgAN. Recently, using genome-wide association studies (GWAS) more loci for disease susceptibility for IgAN have been identified at 17p13, 8p23, 22q12, 1q32 and 6p21.

    National Health Survey on the Prevalence of Urinary Abnormalities in the Population: then and now (1975 to 2012)
    Academy of Medicine, Singapore ; 2012

    Abstract: Introduction: This paper presents the results of a community survey on urinary abnormalities which covered 1/80th of the population of Singapore in 1975. These findings were compared with the data from the Singapore National Service Registrants in 1974 as well as data from a recent survey in Singapore and that of other Asian and Western countries. Materials and Methods: The study covered 18,000 persons aged 15 years and above, representing a sampling fraction of 1/80th of the population. A total of 16,808 respondents attended the fi eld examination centres, of whom 16,497 had their urine sample tested representing 92.7% of the sample population. Results: In the dipstick urine testing at the fi eld examination centres, 769 subjects (4.6%) were found to have urinary abnormalities. Two hundred and eighty-two (36.7%) of these 769 subjects were found to have urinary abnormalities based on urine microscopy constituting a prevalence of 1.71%. The prevalence of proteinuria was 0.63% and for both haematuria and proteinuria was 0.73%. The prevalence for hypertension was 0.43% and renal insufficiency was 0.1%. Discussion: The consensus is that routine screening for chronic kidney disease (CKD) in the general population is not cost effective as the yield is too low. Whilst, most studies showed that screening of the general population was not cost effective, it has been suggested that screening for targeted groups of subjects could help to identify certain risk groups who may benefit from early intervention to prevent or retard the progression of CKD. Conclusion: The prevalence of urinary abnormalities in Singapore has remained the same, now and three decades ago. Key words: Chronic kidney disease, Proteinuria, Screening
