Practice of dialysis access interventional nephrology procedures in the Asia-Pacific region: Getting lay of the land.

AIM: This cross-sectional survey aimed to determine the prevalence of Interventional Nephrology (IN) practice amongst nephrologists in the Asia-Pacific Region (APR), specifically related to dialysis access (DA). METHODS: The Association of VA and intervenTionAl Renal physicians (AVATAR) Foundation from India conducted a multinational online survey amongst nephrologists from the Asia-Pacific to determine the practice of IN in the planning, creation, and management of dialysis access. The treatment modalities, manpower and equipment availability, monthly cost of treatment, specifics of dialysis access interventions, and challenges in the training and practice of IN by nephrologists were included in the survey. RESULTS: Twenty-one countries from the APR participated in the survey. Nephrologists from 18 (85.7%) countries reported performing at least one of the basic dialysis access-related IN procedures, primarily the placement of non-tunnelled central catheters (n-TCC; 71.5%). Only 10 countries (47.6%) reported having an average of <4% of nephrologists performing any of the advanced IN access procedures, the most common being the placement of a peritoneal dialysis (PD) catheter (20%). Lack of formal training (57.14%), time (42.8%), incentive (38%), institutional support (38%), medico-legal protection (28.6%), and prohibitive cost (23.8%) were the main challenges to practice IN. The primary obstacles to implementing the IN training were a lack of funding and skilled personnel. CONCLUSION: The practice of dialysis access-related IN in APR is inadequate, mostly due to a lack of training, backup support, and economic constraints, whereas training in access-related IN is constrained by a lack of a skilled workforce and finances.

Parvovirus B19-Associated Anemia in Kidney Transplant Recipients: A Single-Center Experience.

Parvovirus B19 (PVB19) has tropism to red blood cell progenitors and can be reactivated after organ transplantation. The aim of study was to describe clinical manifestations, laboratory findings, treatments used, and effectiveness in kidney recipients at Viet Duc hospital. A retrospective descriptive study was performed on 663 kidney recipients who were on regular follow-up from 2000 to 2018. PVB19 was detected by polymerase chain reaction PVB19-DNA. Effectiveness of therapy was assessed by Hemoglobin level. Nine out of 663 kidney recipients (1.4%) were diagnosed with PVB19-associated anemia. Eight of these 9 (89%) were diagnosed within the first 3 months following transplantation. All patients had normoscopic anemia; the average reticulocyte proportion and count were 0.15 ± 0.04% and 0.0039 ± 0.0011T/L, respectively. Graft dysfunction was observed in 4/9 (45%) patients. Treatment included reduction of immunosuppression, intravenous immunoglobulin (IVIG), and blood transfusion. All patients responded well to treatment except 1 (11%), who experienced relapse after using low dose of IVIG. PVB19-associated anemia usually occurred early after transplantation and was associated with very low reticulocyte proportion and count. Actual treatment was effective, but the risk of relapse was present.
