[The identification of plasma calcitonin in liver cirrhosis].

Increased levels of plasmatic calcitonin (PC) have been found in patients afflicted with liver cirrhosis (LC). Different circulating polypeptides of calcitonin with contrasting molecular weight (MW) have been observed by way of several methods of identification. The aim of our study is identify these types of PC in patients afflicted with LC, using a gel chromatography technique, comparing them with those obtained from patients with thyroid medullar carcinoma (TMC). A first PC peak with MW of 30,000 daltons (D) corresponding to macromolecular types of PC of LC was observed. Furthermore, a second peak of PC, corresponding to a synthetic human calcitonin and to monomers of PC in patients with TMC was noted. This indicates is a slight increase of monomeric PC in patients with LC, although its biological function is unknown.

[Sepsis: clinical course study of 126 patients in an internal medicine department].

126 cases of sepsis were retrospectively studied in an Internal Medicine Department, giving special attention to the clinical evolution. 67 males and 59 females with a median age of 65 years old were discovered. 92% had one or more diseases, mainly COLD (30%) and diabetes mellitus (28%). The septic sources were urinary (37%) and respiratory (31%). 84% of the germs were gram (-), mainly E. Coli and Proteus sp. A mortality rate of 36% was found, the primary rates being: eighth decade (52%), patients with neoplastic disease (46%), biliary tract diseases (64%), endocarditis (66%), infection by Serratia (60%), Pseudomonas (50%), shock (55%) and DIC (50%). These last two complications were analysed and found to be the more frequent (35% and 6.3% respectively), also being those with higher mortality rate. Finally, the prognostic factors are established based on the results obtained.

[Heterogeneity of calcitonin in liver cirrhosis].

Elevated serum calcitonin (SC) levels have been observed in cirrhotic patients although the biological activity of this hormone in such patients is not known. Twenty one patients diagnosed histologically of alcoholic hepatic cirrhosis (AC) and 12 healthy controls were studied evaluating the degree of hepatocellular failure by means of clinical and biological criteria. Serum calcitonin was determined by means of a radioimmuno assay (RIA) and a radioimmunometric assay (IRMA) in which by combining two monoclonal antibodies, mature calcitonin is determined. These levels almost correspond to levels of biologically active calcitonin. The results obtained show a significant increase in SC in patients with AC when compared to controls, both by RIA (280 +/- 197 pg/ml, p less than 0.001) and IRMA (18 +/- 6 pg/ml, p less than 0.01). Control values were 57 +/- 23 pg/ml and 12 +/- 7 pg/ml respectively. Mean SC values in cirrhotic patients obtained by RIA were 4.9 times greater than their controls while the increase in SC in cirrhotics determined by IRMA was 1.5 times the control, thus obtaining a significant direct correlation between SC and severity of hepatic failure. According to our results, the elevated SC found in cirrhotics is mainly due to immature or non active forms directly related with the degree of severity of the hepatic failure and probably to high Molecular Weight molecules. The slight increase in mature SC in this type of patients is probably due to hormonal mechanism of bone regulation, defendants of hepatic osteodystrophy.
