Legionnaires' Disease in Leukaemic Reticuloendotheliosis

At our hospital 15 cases of leukaemic reticuloendotheliosis and 4 cases of Legionnaires' disease have been diagnosed. 3 patients had both diseases. The clinical findings are reported. It is probable that patients with leukaemic reticuloendotheliosis have an increased susceptibility to Legionnaires' disease. Possible reasons for the decreased resistance are discussed.     

Plasma lyso-phosphatidylcholine concentration is decreased in cancer patients with weight loss and activated inflammatory status

Background  

It has been observed that ras-transformed cell lines in culture have a higher phosphatidylcholine (PC) biosynthesis rate as well as higher PC-degradation rate (increased PC-turnover) than normal cells. In correspondence to these findings, the concentrations of the PC-degradation product lyso-phosphatidylcholine (LPC) in cancer patients were found to be decreased. Our objective was the systematic investigation of the relationship between LPC and inflammatory and nutritional parameters in cancer patients. Therefore, plasma LPC concentrations were assessed in 59 cancer patients and related to nutritional and inflammatory parameters. To determine LPC in blood plasma we developed and validated a HPTLC method.
