Spontaneous spleno-renal and spleno-caval shunts may be anatomically and functionally important in portal hypertension syndromes, as demonstrated by the distinct opacification of the inferior vena cava observed after portal venography with iodine contrast media. Part of the course of these porto-caval anastomotic vessels can be visualized by ultrasonography opposite the left adrenal gland and in the space between the spleen and the left kidney. The images obtained are characteristic enough for the diagnosis of spleno-renal shunt to be suspected before it is confirmed by portal venography, as was the case in the four patients with hepatic cirrhosis reported by the authors.

Clinical trials of the liposomal form of water-soluble x-ray contrast agent triombrast (90 mg of iodine in 1 ml) was carried out in 23 patients with Hodgkin's disease, 9 with liver cirrhosis, and 6 with malignant tumors of different localizations. Distinct images of the liver and spleen appeared 2-2.5 h after intravenous injection of the formulation. They could be observed during 4-6 h by plane radiography. Liposomal hepatolienography permits identification of the structural alteration sites 0.8-1.0 cm in size in these organs. Administration of higher doses of the formulation (more that 0.5 ml/kg) was associated with such side effects as fever and hyperthermia in 30% of patients parallel with the side effects common for iodine-containing x-ray contrast agents. These side effects could be eliminated by previous administration of prednisolone and pipolphen. These side effects were not observed after injection of lower doses of the formulation (less than 0.5 ml/kg) sufficient for an essential improvement of the image contrast during computer-aided tomography.

We report the case of a 68-year-old woman who underwent liver transplantation because of hepatitis-C-induced cirrhosis. She developed iodine-reduced hyperthyroidism postoperatively in temporal relation with cholestatic jaundice. Hepatic biopsies revealed moderate intrahepatic cholestasis and mild lobular inflammatory infiltration with some eosinophils. No histological evidence of acute graft rejection or reactivated hepatitis was found. Treatment with methimazole markedly reduced the serum parameters of cholestasis which, after subtotal thyroidectomy, returned to normal. Liver function recovered, as confirmed by repeated aminopyrine breath tests.

Thyroid function was investigated in patients with liver cirrhosis. 123I uptake after four hours was significantly reduced in the liver cirrhosis group (n = 19) compared with the control group (n = 16) (2.6 +/- 0.3% vs. 5.0 +/- 0.6%, mean +/- SE, p < 0.01). There was no significant difference in the blood inorganic iodine level between the two groups, and the blood 123I count after ingestion of 123I capsules was not significantly different between the two groups. The area of the thyroid was slightly smaller in the cirrhosis group. A thyroid stimulating hormone (TSH) loading test showed no significant difference in the TSH value at any time point. The serum albumin level and prothrombin time were significantly associated with the 4-hour thyroidal 123I uptake (p < 0.01, p < 0.05, respectively). We show that the thyroidal inorganic iodine uptake was reduced in patients with liver cirrhosis and this reduction correlates with the severity of liver cirrhosis. Possible mechanisms include abnormal thyroid iodine transport capacity or reduced turnover of thyroid hormones resulting in a reduction in iodine uptake in liver cirrhosis.

The aim of this study was to estimate thyroid function and the prevalence of thyroid antibodies among HCV seropositive patients. We undertook a screening for thyroid dysfunction, and antithyroperoxidase (ATPO) and antithyroglobulin (ATG) antibodies, in 215 HCV seropositive patients referred for hepatologic consultation, 118 males and 97 females, mean age 44 +/- 14 years, range 16-80 years. No patient was treated with interferon and all were seronegative for HIV. Eighteen patients (8%) had antithyroid antibodies, 12 with ATPO antibodies (5.6%) and 10 with ATG antibodies (4.7%). Four patients had both ATPO and ATG antibodies (1.8%), one case of Graves' disease and 3 cases of autoimmune hypothyroidism found during this study. Five patients (2.3%) had hyperthyroidism, three cases of Graves' disease, one case of iodine load and a case of Grave's disease incidentally diagnosed during medical examination. Eleven patients (5.1%) had hypothyroidism, one case already known and treated without antithyroid antibodies, 4 cases of autoimmune etiology (3 diagnosed in consultation and one already known and compensated hypothyroidism), one case of amiodarone-induced hypothyroidism discovered during this study, 5 cases of hypothyroidism without antibodies (two cases of compensated hypothyroidism with normal TRH stimulating test, two cases with severe liver cirrhosis and one case with chronic hepatitis). Twelve patients had antithyroid antibodies with normal TSH levels. The prevalence of ATPO and ATG antibodies in our study is similar to the prevalence usually observed in general population and does not suggest a pathogenic role of HCV in autoimmune thyroid disorders.

We recently showed that some decrease in thyroid hormone blood levels can effectively and significantly prevent the development of cirrhosis and fulminant hepatic failure and decrease portal pressure in three different rat models. This study was conducted to determine whether hypothyroidism has a beneficial effect over euthyroidism on patients with active liver cirrhosis of different etiologies. The medical files of hypothyroid patients with cirrhosis who were referred to the Tel-Aviv Medical Center between the years 1980 and 1995 were retrospectively evaluated. Of 3,528 patients with biopsy-proven cirrhosis and 4,738 hypothyroid patients who were identified, only 46 (25 female, 54%; mean age, 52.3 +/- 9.1) met the eligibility criteria. The patients suffered from cirrhosis (mean, 9.5 +/- 4.3 years; range, 4-23) and had hypothyroidism (mean, 12 +/- 6 years; range, 4-31). Most patients suffered from hypothyroidism of unknown etiology (85%), whereas the rest had hypothyroidism after surgical/iodine ablation of the gland. In the hypothyroid versus the euthyroid state, a significant negative correlation was found between thyroid-stimulating hormone blood levels and both functional and synthetic liver function tests (p < 0.001). A significant negative correlation was also found between thyroid-stimulating hormone blood levels and clinical deterioration manifested as bleeding varices, the development of ascites, and episodes of encephalopathy. We conclude that in patients with liver cirrhosis, the liver function in the hypothyroid state tend to be better than in the euthyroid state. A mild controlled decreased thyroid function may be beneficial for euthyroid cirrhotic patients.

Abnormal liver function in thyroid disorders may be secondary to thyrotoxicosis or to autoimmune injury to the liver. We report the case of a 36-year-old female who developed jaundice and pruritus with mild cholestasis and moderately elevated transaminase levels. The diagnosis of Graves' disease was made shortly thereafter. Laboratory findings were: alanine and aspartate aminotransferase 219 (IU/I (N: 9-50) and 102 IU/I (N: 10-15) respectively, alkaline phosphatase 336 IU/I (N: 40-135), bilirubin 24 micromol/I (N: 2-23), and gamma-glutamyl transpeptidase 232 IU/I (N: 9-43). Abdominal ultrasonography showed normal bile ducts; echocardiography ruled out heart failure; viral and autoimmune markers for hepatitis and cirrhosis were negative. Percutaneous liver biopsy showed moderate intrahepatic steatosis, anisokaryosis, lymphocyte infiltration in the portal areas, and Kupffer cell hyperplasia. Outcome was favorable after seven months of iodine therapy, confirming the diagnosis of thyrotoxicosis hepatitis.

Anorexia nervosa is a syndrome with multifactorial etiology in which several genetic, biologic, psychological and social factors are involved. Patients affected by anorexia nervosa (AN) may develop multiple endocrine abnormalities, e.g. amenorrhea, hypothalamus-pituitary-adrenal axis hyperactivity, low T3 syndrome and peculiar changes of somatotroph axis function. These endocrine abnormalities are also found after prolonged starvation and may represent an adaptive response developed in order to save energy and proteins. It is still a matter of debate whether these endocrine changes are etiologic or secondary. In fact, several evidences suggest the existence in AN of hypothalamus functional alterations, which may be involved in the development and maintenance of the food intake disorder; on the other hand, the increased CRH secretion seems to be secondary to malnutrition as well as GH hypersecretion coupled to low IGF-I levels; the latter is a common finding in AN, as well as in other undernutrition and malabsorption conditions, type 1 diabetes mellitus, liver cirrhosis and catabolic states. Hypothalamic amenorrhea, which is one of the diagnostic criteria for AN, is not linked only to the reduction of body weight but reflects also deep alterations of gonadotropin secretory pattern. Low T3 syndrome is frequently found in AN; on the other hand, an iodide-induced hypothyroidism is quite uncommon. T3 reduction in AN seems to be an adaptive response to prolonged starvation; however the presence of a simultaneous central dysregulation cannot be excluded. Finally, AN patients frequently show defects in urinary concentration or dilution with inappropriate secretion of antidiuretic hormone, which may be due to intrinsic defects in the neurohypophysis or to abnormalities of its regulatory afferent neurons.

In Western countries, most of the patients with hepatocellular carcinoma (HCC) are not eligible for curative treatments. Intra-arterial treatments have a palliative effect that could lead to extensive tumour necrosis and therefore have been widely used. Arterial embolization, Lipiodol-targeted chemoembolization and intra-arterial injection of radioactive iodine mixed with Lipiodol provided promising results in terms of tumoral growth, but were also responsible for severe side-effects, particularly in patients with cirrhosis. Their influence on survival has been assessed by randomized trials with contradictory results. In patients with advanced cases, embolization alone has limited or no influence on survival, and chemoembolization provided a beneficial effect mostly in patients with viral liver diseases, without liver failure, and with an adequate portal flux. The effects of radioactive iodine either in the treatment of advanced cases or the prevention of recurrences after a curative treatment must be investigated further.

Early esophageal squamous cell carcinoma detected by esophageal iodine staining can be easily treated by endoscopic mucosectomy, and identifying its predictors is important in better selecting candidates to screen for this high-mortality cancer. The common etiologies of elevated mean corpuscular volume (MCV) and esophageal cancer, including folate deficiency, smoking, drinking and high acetaldehyde exposure, suggest testing MCV as such a predictor. Japanese alcoholic men with (n = 65) and without (n = 206) esophageal squamous cell carcinomas, excluding those with liver cirrhosis, were assessed for MCV within 7 days of their last drink, alone or in combination with findings from either the alcohol flushing questionnaire or genotyping to identify inactive aldehyde dehydrogenase-2 (ALDH2*1/2*2) and the less-active form of alcohol dehydrogenase-2 (ADH2*1/2*1), which pose risks for esophageal squamous cell carcinoma. MCV was higher in cancer patients than in the control group. MCV was higher in both groups in those who were heavier smokers, had lower body mass index (BMI), experienced alcohol flushing, and had ALDH2*1/2*2. After adjusting for age, drinking and smoking habits, BMI and ALDH2/ADH2 genotypes, macrocytosis of MCV > or =106 fl was associated with increased risk for esophageal cancer (OR = 2.75). Men with both MCV > or =106 fl and alcohol flushing had an even higher cancer risk (OR = 5.51). The combinations of MCV > or =106 fl with ALDH2*1/2*2 or ADH2*1/2*1 alone, and both ALDH2*1/2*2 and ADH2*1/2*1 (ORs = 11.44, 21.22 and 319.7, respectively) showed consistently higher risk than the corresponding group with MCV <106 fl (ORs = 7.24, 4.71 and 27.01, respectively). In conclusion, MCV measurement, alone or in combination with the markers of alcohol sensitivity, provides a new means of predicting risk for esophageal squamous cell carcinoma in Japanese alcoholic men.
