Progression of autosomal dominant kidney disease: measurement of the stage transitions of chronic kidney disease

Authors: Christopher M Blanchette, Caihua Liang, Deborah P Lubeck, Britt Newsome, Sandro Rossetti, Xiangmei Gu, Benjamin Gutierrez, Nancy D Lin

Autosomal dominant polycystic kidney disease (ADPKD) is a progressive genetic disorder characterized by the development of numerous kidney cysts that result in kidney failure. The results of this study suggest that distribution of patients by age at transition to next stage may be useful for identification of ADPKD patients at risk of rapid progression.

Adherence to risk evaluation and mitigation strategies (REMS) requirements for monthly testing of liver function

Authors: Christopher M Blanchette, Anthony P Nunes, Nancy D Lin, Kathleen M Mortimer, Joshua Noone, Krishna Tangirala, Stephen Johnston, Benjamin Gutierrez

Risk evaluation and mitigation strategies (REMS), as mandated by the FDA for medications with the potential for harm, are increasingly incorporating rigid protocols for patient evaluation, but little is known about compliance with these programs. This study assessed adherence to liver function test (LFT) requirements included in the REMS program for bosentan and the results suggest that the program may not have adequately guaranteed adherence to monthly monitoring of LFTs.
