Immature hemodialysis arteriovenous fistulas: What should we aim for?
Silva,Rui F.; Diniz,Hugo; Relvas,Miguel; Silvano,José; Malheiro,Ana; Coentrão,LuísABSTRACT Arteriovenous fistulas (AVFs) are the first-choice vascular access for most HD patients. Up to 60% of AVFs do not mature adequately, mostly due to stenosis. Surgical and endovascular techniques can rescue up to 80% of these AVFs from primary failure, allowing them to be safely and effectively used in HD, preserving venous capital, and avoiding placement of CVCs and associated complications. This articl...
Chemical peritonitis associated with intraperitoneal vancomycin: A case series
Silvano,José; Pereira,Luciano; Oliveira,Ana; Beco,Ana; Relvas,Miguel; Silva,Rui; Pestana,ManuelABSTRACT Peritonitis is a serious complication in peritoneal dialysis, usually secondary to an infectious cause. Chemical peritonitis is rarer. No case exclusively attributed to vancomycin has been reported in the last 20 years. Data from 4 consecutive patients diagnosed with culture‑negative peritonitis following administration of intraperitoneal vancomycin between May and June 2019 were retrospectively record...
Anti-phospholipase A2 receptor antibodies: Current applications in primary memb...
Relvas,Miguel; Batata,Rodrigo; Nunes,Ana Teresa; Coentrão,LuísBackground: Membranous nephropathy (MN) is among the most common causes of nephrotic syndrome in nondiabetic adults. The podocytic M-type phospholipase A2 receptor (PLA2R) has been identified as the major antigenic target of the immune response that underlies primary membranous nephropathy (PMN). In the last decade, anti-PLA2R antibodies have been seen as promising diagnostic biomarkers for PMN. Other potential...
