Introduction: Coronavirus Disease 2019 (COVID-19) has significantly affected the way healthcare is delivered in Singapore. Healthcare services such as renal transplantation had to rapidly adjust and meet the needs to (1) protect patients and staff, (2) ramp up, conserve or redeploy resources while (3) ensuring that critical services remained operat...
Article
Peritoneal dialysis (PD) is the dialysis modality of choice for many regions. The application of innovative technology has led to the development of new PD devices that reduce the environmental and economic costs of the therapy, as well as miniaturized devices that provide greater freedom for patients.
Article
Introduction: Percutaneous renal biopsy remains critical for the workup of renal allograft dysfunction but is associated with the risk of bleeding. Prophylactic intravenous desmopressin has been proposed to reduce bleeding risk in native renal biopsies, but its efficacy in the renal transplant population is unclear and adverse events such as sever...
Article
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 de...
Article

Peritonitis and exit-site infections (ESI) are major causes of technique failure and morbidity in peritoneal dialysis (PD) patients. Topical mupirocin on the exit-site has been shown to reduce such complications and prolong life in PD. Since the year 2000, such an approach has been adopted for our new incident PD population. We now report the resul...

The ability of cell-free T helper cell products to provide helper activity in B cell antibody responses has been studied. The supernatants of activated T helper cells were sufficient to support hapten-specific IgG antibody responses by B cells in the absence of intact T cells. Moreover, this help was both antigen-specific and major histocompatibili...
