Abstract

Cancer cachexia (CC), a progressive loss of body mass, leads to malnutrition and deficiencies of essential substances including polyunsaturated fatty acids (PUFAs) and L-carnitine (LC). The availability of these 2 compounds determines the rate of eicosanoid synthesis, which modulates inflammatory processes and hemostasis. We compared the effects of administration of emulsions containing long chain triglycerides (LCTs) relative to a 50:50 mix of medium chain triglycerides (MCTs) with LCTs on hemostasis and inflammatory reactions in patients with CC. The study was conducted on 50 patients with CC (23 women, 27 men) aged 66 ± 11 years with a mean loss in body weight of 21 ± 9% in the previous 6 months. Twenty patients received MCTs/LCTs while 30 received LCTs. Total parenteral nutrition (TPN) was administered using the 'all in one' method (25 kcal/kg/day, protein 1.2 g/kg/day). Selected parameters of coagulation and inflammatory state were evaluated on days 1, 5, 7 and 11 of TPN. Initial concentrations of D-dimers, fibrinogen, plasminogen activator inhibitor type 1 (PAI-1), fibronectin, CRP and IL-6 significantly exceeded the upper limit of the reference values. After 10 days of TPN, we detected significant differences in inflamma...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.
