Sodium pyruvate infusions in patients with alcoholic liver disease. Preliminary report.

Pyruvate has been shown to benefit cellular energy metabolism and to reduce free radical formation. Concerning gastrointestinal side effects of orally administered sodium pyruvate, in this pilot study we investigated the therapeutic effectiveness of sodium pyruvate infusions in patients with alcoholic liver disease (ALD). Fifteen patients with ALD received sodium pyruvate infusions for: (1) 10 days (54-86.4 g pyruvate daily, 150-180 mg/min., 6-8 h); and (2) 15 days (50-54 g daily, 100 mg/min., 6 h). Sodium pyruvate treatment resulted in significantly decreased serum AST (p<0.03), ALT (p<0.03), AP (p<0.004), GGT (p<0.05), and total bilirubin (p<0.04). Improvement of liver function was also evident from the significantly decreased Combined Clinical and Laboratory Index (from 6.50+/-0.71, to 3.92+/-0.84, p<0.001), and Liver Damage Score (from 3.83+/-0.71 to 2.75+/-0.58, p<0.01). The two therapy schedules used showed similar results. Unchanged serum pyruvate, lactate, and glucose confirmed the good utilization of pyruvate. Tolerance of sodium pyruvate treatment was very good in 26.09% and good in 68.94% of the observations. Our results showed good therapeutic effectiveness and good tolerance of sodium pyruvate infusions in patients with ALD. This is possibly due to the rapid gain of ATP and GTP, required to redress defective cells, and to antioxidant action of pyruvate.

Clinical meaning of GGT activity in follow-up of patients with alcohol-related liver injury and cholestasis.

The dynamics of GGT was investigated in three groups of patients after removing some primary causes of GGT increase. Group A included 34 patients with alcohol-related liver disease, group B included 16 patients with alcoholic liver injury and cholestasis, caused by concomitant alcoholic pancreatitis and group C included 17 patients with extrahepatic cholestasis, caused by choledocholithiasis. Follow-up assays of GGT were performed on the 7th, 14th and 30th days. Our results showed that the dynamics of GGT was more rapid after removing the cause for cholestasis than in stopping alcohol consumption in patients with chronic liver diseases. On the 14th day more than a 50% decrease in GGT activity was noted in 20% of the patients from groups A and B and in almost all cases from group C. On the 30th day, the reference range of GGT was not attained by any of the patients with liver disease nor in five patients from group C. No significant correlation was found between the severity of liver damage and the extent of GGT increase at the beginning and at the end of the follow-up period.

[The protease inhibitor treatment of the disseminated intravascular coagulation syndrome in patients with liver cirrhosis].

The results of the treatment of the syndrome of disseminated intravascular coagulopathy (DIC) in 41 patients with liver cirrhosis are reported. A relation between the severity of the liver impairment and the degree of the increase of the fibrin split products (FSP) was established. FSP above 100 micrograms/ml were found in patients with III class liver failure according to Child-Turcotte-Pugh and rating above 6.5 according to Z. Krŭstev. The administration of 30,000-60,000 U of the protease inhibitor contrykal led to mastering of the hemorrhagic diathesis in 19 of 21 patients (group A). The increased FSP in the serum fell (chi 2 = 5.79; p less than 0.001). In contrast, the administration of PAMBA and styptanon did not affect the hemorrhagic diathesis and DIC syndrome in 16 of 20 other patients (group B--chi 3 = 20.54; p less than 0.001). The authors recommend protease inhibitors as the treatment of choice of DIC syndrome in liver cirrhosis. Only in case of lack of effect should heparin be added.

[A modified Sugiura operation].

This is the first report in Bulgaria of the application of the modified method of Sugiura. The operation is less traumatic than the original one, the postoperative mortality is essentially reduced, patient survival to 7 years is increased and there is no encephalopathy. This operation is technically easier to perform than splenorectal anastomoses and may be performed both as planned and emergency intervention. Two personal observations on two patients operated by the modified technique of Sugiura are reported. The results were very good.

[A modified Sugiura operation].

The modified method of Sugiura is reported for the first time in Bulgaria. The operation is less traumatic than the original one, the postoperative case fatality rate is lower, patient survival rate up to 7 years is high and there is no encephalopathy. This operative technique is more practicable than splenorenal anastomosis and may be applied both for planned and for emergency operations. Two patients have been operated by the authors, using the modified technique of Sugiura, with very good results.

[Role of hepatitis B virus infection in chronic glomerulonephritis].

This study included 60 patients suffering from chronic glomerulonephritis (GN), confirmed by punch biopsy of the kidney. HBs antigen (Ag) was found in the sera of 5 patients, whereas anti-HBs and/or anti-HBc antibodies were found in 3 others. Of the 139 subjects carrying HBsAg or anti-HBc antibodies 117 suffered from chronic liver disease and 3 from chronic GN. Of the 11 patients afflicted with chronic GN and one with a hepatitis B virus (HBV) infection 9 had GN with IgA deposits and the other 2 had membranoproliferative GN. The renal tissue of these 11 patients was examined for the presence of HBs. HBc and HBe antigens using monoclonal antibodies. Virus particles were unsuccessfully sought by electron microscopy. It is possible that, in some patients infected with HBV and afflicted with chronic liver disease, the IgA deposits in the glomeruli result from the perturbed liver metabolism.

[Circadian changes in gastric acidity during drug therapy of duodenal ulcer].

The circadian change of gastric acidity was studied in 9 patients and 2 controls. Five patients were treated with gastrozepin, two with vicalin and buscolysin, two with biomet according to a schedule. Gastric content was aspirated at fixed intervals and pH determined separately of each portion. The data were juxtaposed to those of the gastric probe prior to the beginning of the treatment. They revealed that with the treatment with gastrozepin and biomet, the lowest pH values during the day were higher, with a statisticall significance, than those obtained at basal conditions prior to the treatment. During the night, pH over 3 was observed only in the treatment with biomet. The methodical conditions used ate suitable both for clinical-pharmacological investigations and for individualization of the treatment of some patients that failed to respond to the ordinary therapeutic combinations.

Quantitative assessment of severity of biliary tract infection.

BACKGROUND/AIMS: It is very important for physicians to evaluate the severity of the biliary infection. At the moment, there is no useful quantitative system. In this study, we propose a scoring system for assessing the severity of biliary infections and evaluation of the efficacy of antibacterial and endoscopic treatments. MATERIALS AND METHODS: We created a biliary tract infection score (BTIS) including local physical and ultrasound findings, signs of inflammation and hepatobiliary involvement. The BTIS was calculated in 317 patients: group I-155 pts with cholecystitis and cholangitis, treated only by antibiotics and group II-162 pts with acute cholangitis treated by endoscopic procedures. RESULTS: The BTIS allowed the differentiation of the severity of biliary infections: 15.50 +/- 0.52 in acute cholangitis group and 5.77 +/- 2.79 in group I (p < 0.001). The BTIS significantly decreased after antibacterial therapy (excluding only the cefotiam subgroup) and in endoscopicaly treated patients. CONCLUSIONS: The BTIS is a combination of simple, reliable, acceptable and low cost parameters, reflecting the principal pathological processes and degree of abnormalities. A BTIS facilitated the assessment of severity of biliary infection and comparison of the results of various methods of treatment.
