ABSTRACT

Increase in serum ferritin, which occurs in 40 to 70% of chronic alcoholics, remains poorly understood. We tested the hypothesis which links hyperferritinemia in chronic alcoholism not only to ferritin release from damaged liver cells, but also to increased ferritin secretion. Fifty-eight chronic alcoholic patients hospitalized for alcohol withdrawal were subdivided into three groups according to liver damage. Their serum levels of ferritin and ferritin bound to concanavalin A (ferritin Con A, which represents glycosylated, i.e., secreted ferritin) were measured serially on days 1, 7, and 11 of withdrawal and compared with a control group. The results were: (1) Total serum ferritin increased in alcoholics. Both free and Con A ferritins increased in equal proportions, the ferritin Con A to total ferritin ratio remaining unchanged. The increase was dependent on liver disease, as both free and Con A ferritins increased significantly with the severity of liver illness. Serum ferritin levels were related to iron status: it correlated with hepatic iron concentration (obtained in 19 patients); however, high ferritin values were not related to the degree of iron overload, which remained low. Finally, there was no correlation between serum ferritin and the average of alcohol consumption. (2) Both free and Con A ferritin decreased by about 40% during alcohol withdrawal. In conclusion, we have demonstrated that (1) total serum ferritin is increased in chronic alcoholism and (2) that this ferritin increase is due in part to an increase in ferritin Con A, proof of the induction of ferritin secretion by alcohol in humans.

ABSTRACT

Haemorheological parameters were studied in 138 alcoholic subjects at different stages of the liver disease, compared to non alcoholic liver diseases and controls. Results showed 1) a decrease in whole blood filterability in the three groups of alcoholic patients associated with a decrease in erythrocyte ATP level, 2) an increase in blood and plasma viscosities, 3) morphological alterations visualized by scanning electron microscopy. These disturbances are correlated to the abnormalities of red cell membrane lipids composition: increase in cholesterol/phospholipids ratio, increase in saturated fatty acids and decrease in polyunsaturated fatty acids (arachidonic and linoleic acids). The responsibility of alcohol itself, in the genesis of these disturbances has been demonstrated by acute alcohol drinking experiments in healthy subjects.

ABSTRACT

Hemorheological parameters were studied in 218 subjects: 129 alcoholic liver diseases, 19 alcoholic patients without liver damage, 20 liver diseases without alcoholism and 50 controls. Whole blood filtration (WBF) is significantly decreased in the group of alcoholic patients; whole blood and plasma viscosity are increased in the groups of alcoholic patients as well as in the group of non alcoholic liver diseases. The liver damage seems not to be a determining factor to the genesis of filterability impairment. Alcohol and/or one of its metabolites induce erythrocytes morphological alterations (scanning electro-microscopy) correlated with some alterations of the RBC membrane lipids content (increased cholesterol/phospholipids ratio). It is suggested that these hemorheological patterns must be discussed in cases of alcoholic liver diseases as well as in following up alcohol withdrawal.

ABSTRACT

Sterility of blood products is a cardinal contributor to patient safety. Bacteriologic controls of stable products comply with strict regulations, but legislation imposes only limited constraints in the case of perishable products, such as packed red cells (RBCs) or fresh-frozen plasma (FFP). Therefore, it is essential to monitor the sterility of aseptic donations from uninfected donors. Such bacteriologic monitoring can now be carried out through a tertiary bag (containing a soybean casein culture medium) connected to the classical double-pack system. This system does not jeopardize the sterility of the whole system, as the connection is tightly stoppered by a membrane. After the blood drawing, this tertiary bag is filled with 5 ml of blood, and separated from the rest of the system. It is then incubated for 3 days at 30 degrees C and for 14 days at 22 degrees C, to test for eventual bacteriologic or fungal contamination. In order to check the feasibility of this technique, we studied 76 blood drawings in the control laboratory of the blood center, and the results confirm the value of this system.

ABSTRACT

The present study tries to evaluate the diagnosit value in malignant hepatic tumors of polyamines, of which the relationship with cellular kinetics is known, and histamine, of which catabolism follows a similar pathway. One hundred and fifty six patients were studied: 53 with malignant liver tumors (27 primary, 26 metastatic) and 103 with non-tumoral liver diseases of which 65 were cirrhotic and 38 non-cirrhotic. Erythrocyte polyamines (spermidine and spermine) and histamine levels were assayed. The results indicate the following. 1. Polyamine levels were significantly increased (a) in cirrhotic patients, not only when compared with controls (p less than 10(-8)), but also when compared with the non-cirrhotic patients (p less than 10(-7)); (b) in primary malignant hepatic tumors (p less than 10(-3)). 2. Histamine was significantly increased (a) in the non-tumoral liver diseases (p less than 10(-4)), but with no difference between cirrhotic and non-cirrhotic patients; (b) in the secondary malignant tumor patients, histamine levels were lower than in primary tumor patients (p less than 0.04). 3. There was no correlation, in all groups studied, between polyamine and histamine levels. These results suggest the following practical implications. 1. For non-tumor liver diseases, appreciably increased polyamine levels may represent a further argument favoring a cirrhotic condition. 2. In diagnosing hepatic scintigraphic defects, increased polyamine levels would suggest a primary malignant hepatic tumor; low histamine levels are more in favor of a secondary malignant hepatic process.

ABSTRACT

Ultrasonically guided fine needle aspiration biopsy is known to be of great value in the diagnosis of malignant liver disease, with an overall accuracy rate of 73-94 p. 100. However, investigators have essentially reported cases of liver metastases. In this report, we examined the diagnostic value of this method in the specific case of tumors associated with cirrhosis. Twenty-seven patients with cirrhosis (20 alcoholic, 4 post-hepatitis, 3 hemochromatosis) with ultrasonically suspected hepatic malignancy were studied. They all presented severe blood clotting disturbances and/or ascites. At the end of the study, all patients had proven malignancy (by post mortem biopsy in 14 cases and/or serum AFP greater than 500 microgram/l in 17 cases). There were 25 primary and 2 metastatic tumors. Twenty-nine fine needle aspiration biopsies were performed under ultrasonic guidance. material suitable for cytologic evaluation was obtained in 25 patients. In 14 cases, a diagnosis of malignant involvement of the liver was firmly established by cytological examination; it was suggested in 4 other cases. Tumor typing was possible in 12 primary and 2 metastatic tumors, in agreement with the proven diagnosis. The present study shows that fine needle aspiration biopsy under ultrasound guidance is a safe and accurate diagnostic procedure in malignant liver disease associated with cirrhosis.

ABSTRACT

alpha-L-fucosidase, a lysosomal enzyme which catabolizes fucoproteins, was studied in sera from 30 controls, 32 patients with primary hepatic carcinomas, 24 patients with secondary metastatic liver carcinomas and 36 patients with cirrhosis. Serum alpha-L-fucosidase was increased in primary hepatic carcinomas (145.5 +/- 12 nkat per liter) with a high statistical significance versus controls (51.4 +/- 4.5 - p less than 10(-7], secondary metastatic liver carcinomas (58.9 +/- 6.4 - p less than 10(-5] and cirrhotics (71.3 +/- 6 - p less than 10(-5). A level exceeding 110 was a useful marker for the diagnosis of primary hepatic carcinoma with 75% sensitivity and 90% specificity.

ABSTRACT

Antipyrine metabolic clearance and BSP fractional (K1) clearance relationship in liver disease is the object of this study. 47 patients have been examined (liver cirrhosis: 17, liver disease without cirrhosis: 15, patients with no liver disease: 15). Results are as follows: antipyrine metabolic clearance is significantly lower in patients with cirrhosis; BSP fractional clearance is significantly lower in liver disease with and without cirrhosis; the clearances are significantly linked in liver cirrhosis patients, but not in the other patient groups. The role of liver cell deficiency and blood flow decrease is discussed with result interpretation.

ABSTRACT

The authors report a case of temporal arteritis accompanied with appearance of "cold areas" on the liver scan, regressing after steroid therapy. This observation confirms the existence of hepatic manifestation in giant cell arteritis and evokes a discussion of their mechanism. A hypothesis of hepatic ischemia is proposed.
