Gastrointestinal bleeding associated with antithrombotic therapy in the elderly in Japan
Abstract
Background/aims: We summarize data of patients with gastrointestinal bleeding (GIB) and discuss the relationship between antithrombotic drug use and age in patients with GIB.
Methodology: One-hundred and twenty patients with GIB were divided into two groups according to age (=75 years old and <75 years old). The causes and clinical outcome of each group were compared.
Results: Forty-two patients received antithrombotic therapy. The main antithrombotic drugs were low dose aspirin (38 patients), ticlopidine (5 patients) and warfarin (3 patients). Compared with younger GIB patients, elderly patients had more coexisting illness and antithrombotic drugs. In patients taking antithrombotic drugs, upper GIB is more frequent than those not taking antithrombotic drugs (p<0.05) and antithrombotic drugs were the risk for GIB from erosive lesions of the esophagus or stomach. In the lower gastrointestinal tract, there was no difference of incidence related to antithrombotic use. The initial endoscopic hemostasis was performed in 14 patients. Eight varices patients received endoscopic vanding and 6 of 43 gastroduodenal ulcer patients had mechanical clip hemostasis.
Conclusions: From our findings, antithrombotic drugs were considered to be a risk for GIB. It might be important to prevent or minimize GIB in elderly patients prescribed antithrombotic drugs.
