Impaired fibrinolysis is a common finding in obese humans. This condition is now considered as an established risk factor for thromboembolic complications. Furthermore, obesity is characterized by a specific pattern of circulating concentrations of fat-cell products interleukin-6 (IL-6), leptin, and adiponectin. The aim of our study was to investigate the relationship between these proteins and selected variables of the fibrinolytic system in 74 mildly hypertensive, overweight subjects. Circulating IL-6 and leptin levels showed a positive association with BMI (r = 0.24, p = 0.04 and r = 0.70, p < 0.0001), whereas adiponectin was not correlated to BMI. Interestingly, IL-6 was also positively associated with t-PA/PAI-1 complexes after adjustment for BMI and other anthropometric variables. Leptin was positively correlated with PAI-1 activity and antigen (r = 0.32, p = 0.006 and r = 0.37, p < 0.001, respectively) and negatively with t-PA activity (r = -0.27, p = 0.03). However, these associations lost significance after correction for BMI or HOMA, an insulin sensitivity index. In contrast, adiponectin levels were independently and negatively correlated with PAI-1 antigen (r = -0.26, p = 0.04, after correction for BMI). In conclusion, our study provides further evidence that IL-6, leptin, and adiponectin are associated with impaired fibrinolysis in overweight hypertensive humans.

We report a case of matched unrelated bone marrow transplant (BMT) in a morbidly obese patient with acute myeloblastic leukaemia. The challenges presented in the management of this case included the calculation of chemotherapy and radiotherapy doses and the acute presentation of obstructive sleep apnea. Despite these difficulties, an ultimately successful outcome was obtained, indicating that although associated with increased risk of peri-transplant morbidity, obesity need not represent a contraindication to BMT.
