We report a female patient diagnosed of Gitelman disease who suffered from severe hypokalemia and hypomagnesemia during pregnancy. We discuss the therapeutic approach and materno-fetal outcome.
Several uremic toxins have been identified and related to higher rates of morbidity and mortality in dialysis patients. Bisphenol A (BPA) accumulates in patients with chronic kidney disease. The aim of this study is to demonstrate the usefulness of online hemodiafiltration (OL-HDF) in reducing BPA levels. Thirty stable hemodialysis patients were selected to participate in this paired study. During three periods of 3 weeks each, patients were switched from high-flux hemodialysis (HF-HD) to OL-HDF, and back to HF-HD. BPA levels were measured in the last session of each period (pre- and post-dialysis) using ELISA and HPLC. Twenty-two patients (mean age 73 ± 14 years; 86.4% males) were included. Measurements of BPA levels by HPLC and ELISA assays showed a weak but significant correlation (r = 0.218, P = 0.012). BPA levels decreased in the OL-HDF period of hemodialysis, in contrast to the HF-HD period when they remained stable (P = 0.002). In conclusion, OL-HDF reduced BPA levels in dialysis patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
