New oral spherical carbon adsorbent effectively reduces serum indoxyl sulfate levels in moderate to advanced chronic kidney disease patients: a multicenter, prospective, open-label study.


ABSTRACT: BACKGROUND:Elevated levels of serum indoxyl sulfate (IS) have been linked to cardiovascular complications in patients with chronic kidney disease (CKD). Oral sorbent therapy using spherical carbons selectively attenuates IS accumulation in CKD patients. This study aimed to investigate whether oral administration of a new oral spherical carbon adsorbent (OSCA), reduces serum IS levels in moderate to severe CKD patients. METHODS:This prospective, multicenter, open-label study enrolled patients with CKD stages 3-5. Patients were prescribed OSCA for 8?weeks (6?g daily in 3 doses) in addition to standard management. Serum IS levels were measured at baseline and 4 and 8?weeks of treatment with OSCA. RESULTS:A total of 118 patients were enrolled and 87 eligible patients completed 8?weeks of study. The mean age of the study subjects was 62.8?±?13.7?years, and 80.5% were male. Baseline levels of serum IS were negatively correlated with estimated glomerular filtration rate (eGFR) (r?=?-?0.406, P?
