Abstract: The invention provides, in certain embodiments, a method of preventing and/or treating peritoneal injury and/or diminished function by administering an effective amount of one or more inhibitors of JAK. The invention also provides a pharmaceutical composition including a JAK inhibitor for the treatment of peritoneal injury and/or diminished function. In another aspect, the invention provides a method of detecting an indicator of peritoneal injury. The method entails assaying a biological sample for periostin, wherein the presence of periostin at an elevated level indicates the presence and/or degree of peritoneal injury. Also provided, are methods of identifying subject for treatment of peritoneal injury and/or diminished function, methods of determining progression of these conditions, as well as methods of determining subjects' response to treatment.

Abstract: The invention provides, in certain embodiments, a method of detecting an indicator of renal injury or renal disease. The method entails assaying a urine sample for periostin, wherein the presence of periostin at an elevated level indicates the presence and/or degree of renal injury or renal disease. Also provided, are methods of determining progression of these conditions, as well as methods of determining subjects' response to treatment.

Abstract: The invention provides, in certain embodiments, a method of assaying an indicator of, and treating, renal injury or renal disease. The method entails assaying a urine sample for periostin, wherein the presence of periostin at an elevated level indicates the presence and/or degree of renal injury or renal disease. The method also involves prescribing, initiating, or altering prophylaxis or therapy for renal injury or renal disease. Also provided, are methods of determining progression of these conditions, as well as methods of determining subjects' response to treatment.
