Abstract

Cisplatin is one of the most widely used agents in cancer treatment. Cisplatin regimens can lead to a more or less pronounced hyponatremia in 4 to 10% of cases due to salt wasting with hypomagnesemia and normokaliemia. Functional and renal failure and orthostatic hypotension can be observed. A 54-year-old woman with brain metastases of a non-small-cell lung cancer was given a chemotherapy regimen containing cisplatin. Hyponatremia with confusion occurred after each cisplatin perfusion. The diagnosis retained was cisplatin-induced salt wasting. The patient was given salt prolonged supplementation and carboplatin was substituted for cisplatin in the chemotherapy regimen. Hyponatremia frequently occurs in cancer patients. Cisplatin-induced hyponatremia requires specific management. Treatment is based on sodium intake which sometimes takes several months to replete stores. Carboplatin can be used instead of cisplatin in case of major hyponatremia.

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.
