In this study, we investigated the effects of KBT-3022 (ethyl 2-[4,5-bis(4-methoxyphenyl)-thiazol-2-yl]pyrrol-1-ylacetate) , a potent and long-lasting anti-platelet agent, in several experimental thrombosis models and compared them with those of other anti-platelet drugs. Oral administration of KBT-3022 prevented arachidonic acid-induced death due to pulmonary embolism in mice and rabbits with respective ED50 values of 0.29 and 0.12 mg/kg. The protective effect of acetylsalicylic acid (ASA) against mortality was weaker than that of KBT-3022, and ticlopidine hydrochloride (TP) showed no such effect in these models. In a guinea pig arterio-venous shunt model, the inhibition by KBT-3022 of thrombus formation on a silk thread inserted into the shunt was dose-dependent and 300 and 30 times more potent than the inhibition obtained with ASA and indomethacin, respectively. In a model of aortic thrombosis induced by perivascular application of 20% silver nitrate solution, KBT-3022 (1 mg/kg, p.o.) inhibited thrombus formation significantly, ASA (100 mg/kg, p.o.) tended to inhibit it, and TP had no effect. However, in a stasis-induced venous thrombosis model in guinea pigs, TP inhibited thrombus formation significantly, but KBT-3022 and ASA were ineffective. These results suggest that KBT-3022 may be a useful drug for the treatment and/or prophylaxis of thrombus formation in shunts and aortic thrombosis.

Central venous lines were used to administer total parenteral nutrition at our institution. In an attempt to reduce line sepsis, silver impregnated cuff central lines (Hohn catheter) were adopted as standard of practice. Using a comprehensive morbidity and mortality database, 134 patients with Hohn catheters were compared to 252 patients who had polypropylene central line. The incidence of central line sepsis was increased with Hohn catheters to 23 of 134 (17.2%). This compared to 8 of 252 (3.2%) patients with polypropylene catheters (P < 0.0001). Also, an increased incidence of pulmonary embolism of 15 of 134 (11.2%) in patients with Hohn catheters was observed as compared to 2 of 252 (0.8%) with a polypropylene catheter (P < 0.0001). Insertion of Hohn catheters through the intrajugular vein was judged to be more difficult than polypropylene catheters. This may cause increased trauma to the vein resulting in a higher incidence of line infection and pulmonary embolism.

Pulmonary embolism (PE) is common and associated with significant morbidity and mortality. An association between obesity and PE has been suggested, but the nature of the association has not been well defined. We performed a prospective cohort study of 87,226 women in the Nurses' Health Study (1984-2002) to define the association between BMI and the risk of incident PE. Primary exposure was BMI (<22.5, 22.5-24.9, 25.0-27.4, 27.5-29.9, 30.0-34.9, and >or=35.0 kg/m(2)). Primary outcome was idiopathic PE (medical record confirmed cases of PE not associated with prior surgery, trauma, or malignancy). Secondary analysis of nonidiopathic PE was also performed. Multivariable Cox proportional hazards models were controlled for age, physical activity, caloric intake, smoking, pack-years, race, spouse's educational attainment, parity, menopause, nonaspirin nonsteroidal anti-inflammatory drugs, warfarin, multivitamin supplements, hypertension, coronary heart disease, and rheumatological disease. There were 157 incident idiopathic PE and 338 nonidiopathic PE. There was a strong positive association between BMI, the risk of idiopathic PE (relative risk (RR) = 1.08 (95% confidence interval (CI), 1.06-1.10) per 1 kg/m(2) increase in BMI, P < 0.001) and nonidiopathic PE (RR = 1.08 (95% CI, 1.07-1.10), P < 0.001). The association was linear, and apparent even with modest increases in BMI (22.5-25 kg/m(2)). The risk increased nearly sixfold among subjects with BMI >or=35 kg/m(2), and was present in multiple subgroups. Increasing BMI has a strong, linear association with the development of PE in women. Clinicians should consider BMI when assessing the risk of PE in their patients.
