A gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine.The tumors are thought to grow from specialized cells found in the gastrointestinal tract called interstitial cells of Cajal (ICCs) or precursors to these cells. gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine.
Warfarin Maintenance Dosing and INR Recall Algorithms These algorithms are intended to be used after the patient has gone through the initiation period and a chronic maintenance dose has been established. Target INR 2.5 (Range 2.0-3.0) INR â¤1.5 1.51-1.99 2.00-3.00 3.01-4.00 4.01-4.99 5.00-10.00 >10.00 Dose Change1
In addition, the percentage of patients with a follow-up INR higher than 3.5 -- which would typically trigger a change in warfarin dose in patients taking antibiotics was significantly higher in the antibiotic and sick control groups (13.5% and 15.1%, respectively) compared with the stable controls (9.2%).ction Points. 1  Upper respiratory tract infection increases the risk of excessive anticoagulation even without antibiotics. 2  Antibiotics interfering with warfarin metabolism (metronidazole and trimethoprim-sulfamethoxazole) were more likely to result in more clinically concerning increases in INR.
