Fifty-two patients on regular haemodialysis at our institution were evaluated for the presence of HCV infection. Evaluation included detailed history, clinical examination, and monthly screening for anti-HCV antibody, liver enzymes (ALT, AST), serum iron and ferritin. Also, three-monthly screening for other viral markers, HBV (HBsAg, HBsAb, HBcAb), CMV (IgG and IgM), EBV, and HIV. Anti-HCV antibody was found in 21 patients (40.4%). There was a significant (P less than 0.05) relationship between presence of anti-HCV antibody and proportion of patients who received blood transfusion. During a 12-month follow-up, four (11.4%) patients seroconverted to be Anti-HCV positive while one case (4.8%) seroconverted to be anti-HCV negative. The frequency of elevation of liver enzymes was significantly higher in Anti-HCV positive cases (14/18) than in negative cases (11/28, P = 0.01). Evaluation of liver biopsies of 13 patients showed chronic persistent hepatitis in six and chronic active hepatitis in seven cases. We concluded that hepatitis C is a common problem among chronic haemodialysis patients at our institution; HCV infection is documented in 70% of all clinically diagnosed NANB hepatitis. Presence of anti-HCV antibodies cannot differentiate between active and past infection and cases with early HCV infection can be missed when relying on the mere detection of anti-HCV antibodies.

The results of the study have shown that the nutrition of rural population is characterized by excessive consumption of bread and baked products, by high content of phosphorus, magnesium and iron, low content of animal proteins, vegetable oils, calcium, vitamins A, ascorbic acid and riboflavin. The incidence of cardiovascular, respiratory and alimentary diseases in this group of population was rather high. The nutrition of students is characterized by excessive consumption of polysaccharides, vegetable oils, thiamine, niacin, ascorbic acid (in winter-spring period), and calcium. Diseases associated with nutrition disorders (obesity, hepatitis, cholecystitis, colitis) are most often recorded in this group of population.

Swaziland is a kingdom with 800,000 inhabitants bordering on Mozambique and South Africa with about 50% of the population under 15 years of age. The experience of a nurse in a small clinic in the course of several years is recounted. Swaziland ranks 3rd in the world in alcohol abuse which often leads to wounds requiring suturing. Penicillin is given prophylactically with a paracetamol preparation for analgesia. As a rule, every injured person will get a .5 ml tetanus injection for prophylaxis. The most serious conditions of polyclinic patients are hepatitis, bilharzia, diarrhea, pellagra, pneumonia, and malnutrition. A great number of patients have sexually transmitted diseases, and the rate of AIDS infection is not known. According to 1 study 60-80% of the population in reproductive age will die of AIDS in the course of a 5-year period. The majority of people are impervious to counseling about their sexual behavior in spite of educational programs on the radio, in schools, and in work places. Condoms are not popular, since they are not considered manly. Pregnant women receive iron and multivitamin tablets in the course of pregnancy. Many pregnant women are anemic, and 70% give birth at home, the rest in a hospital or clinic. During delivery they get no analgesia, and there are few complications. The average weight of the newborn is 3.5 kg, although none of the women are under 150 cm. A little after birth all children are vaccinated with bacillus Calmette-Guerin (BCG) and polio, later with diphtheria-pertussis-tetanus (DPT) and measles.

A 28-year-old man who had suffered from erythropoietic protoporphyria since infancy was referred because of worsening photosensitivity. Conventional therapy with beta-carotene, terfenadine and topical sunscreens was ineffective or not tolerated, and he was treated with transfusions of washed packed cells. Unexpectedly, his photosensitivity deteriorated further, his whole blood protoporphyrin levels doubled and he developed abnormal liver function tests. This is the first report of such an adverse response to blood transfusion therapy for erythropoietic protoporphyria and may have been related to subclinical hepatitis or the increased iron load associated with blood transfusion.

We evaluated the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in 78 Italian patients with hereditary hemochromatosis as well as the relation between HCV antibody (anti-HCV) status, hepatitis B surface antigen (HBsAg) and liver histology. None of the patients had been transfused or ever consumed more than 60 g of alcohol per day. Eighteen showed histological signs of chronic hepatitis, active cirrhosis was present in 12, chronic active hepatitis in 4 and chronic persistent hepatitis in 2. Liver fibrosis or cirrhosis without inflammatory activity was observed in 31 subjects, whereas liver histology was normal except for iron overload in 18. The prevalence of HBsAg in the whole series was 5% and of anti-HCV was 20.5%. The prevalence of HBsAg and anti-HCV was significantly higher in the chronic hepatitis group than in the fibrosis/cirrhosis (p = 0.01) and the normal groups (p < 0.01). Fourteen of 18 hereditary hemochromatosis patients with chronic hepatitis were HBsAg (4) or anti-HCV (10) positive and all the latter subgroup had HCV-RNA in their serum as shown by the polymerase chain reaction. Although most of the patients with associated chronic hepatitis had cirrhosis, their serum ferritin levels and amount of mobilizable iron were significantly lower than those of the fibrosis/cirrhosis group (p < 0.01). This indicates that hepatitis viral infection acts synergistically with iron in accelerating the development of liver damage.

There is a growing body of experimental and clinical evidence to suggest that oral or rectal administration of 5-ASA or 5-ASA conjugates is associated with significant adverse side effects including pancreatitis, hepatitis, and renal toxicity. The objective of this study was to assess the ability of 5-ASA to interact with low-molecular-weight iron to yield oxygen-derived free radicals and to determine whether these oxidants could damage model biological compounds. We found that 5-ASA was very effective at chelating ferric iron (Fe3+), and it rapidly reduced Fe3+ to the ferrous form (Fe2+). Addition of the 5-ASA/Fe2+ chelate to solutions containing polyunsaturated fatty acids or deoxyribose resulted in lipid peroxidation and oxidative carbohydrate degradation, respectively. These results are consistent with the formation of the highly reactive (and cytotoxic) hydroxyl radical. Formation of this free radical species was confirmed by the ability of hydroxyl radical scavengers (dimethyl sulfoxide, dimethyl thiourea) to inhibit the 5-ASA/Fe-mediated oxidative reactions. Maximum hydroxyl radical formation was achieved at a 5-ASA-to-Fe3+ ratio of 1.0 (20 microM 5-ASA and 20 microM Fe3+). Increasing this ratio significantly inhibited OH. formation with a concomitant reduction in lipid peroxidation and deoxyribose degradation. Finally, we demonstrated that 5-ASA promotes the reductive release of Fe3+ from ferritin. Data obtained in this study suggest that 5-ASA may, under certain conditions, promote the formation of potentially injurious free radical species. These oxidative reactions may contribute to some of the adverse side effects known to be associated with the newer preparations of 5-ASA.

The authors studied serum neopterin in 106 patients with beta thalassaemia major. A good correlation was found between neopterin values and glutamic pyruvic transaminase (GPT) mean values of the last 6 months, whereas no correlation was found between neopterin values and some siderosis indexes (iron/body weight, total accumulated iron). A statistically significant correlation was found between neopterin values (greater than 10 nM/L vs. less than 10 nM/L) and histological liver findings (chronic hepatitis vs. siderosis). Neopterin values were also statistically different between splenectomized and not splenectomized patients. Moreover serum neopterin was higher in HCV-Ab positive than in HCV-Ab negative patients, and 91.6% of the HCV-Ab positive group also showed histological signs of chronic hepatitis. These data suggest that increased serum neopterin might help to identify chronic C hepatitis in thalassaemic patients.

In this study, the target-specific behavior of magnetic resonance (MR) imaging contrast agents directed at human hepatic asialoglycoprotein (ASG) receptors was evaluated in vitro with use of two novel assays: relaxation time measurements of incubated human cell membrane solutions and iron staining of biopsy samples. Specific uptake of ASG receptor-directed agents was demonstrated in human samples of normal liver tissue, areas of hepatitis, regenerating nodules, areas of focal nodular hyperplasia, and hepatic adenomas. A conventional iron oxide preparation not directed at ASG receptors failed to demonstrate specific uptake in these tissues. Attachment of the ASG receptor-directed agents was competitively blocked with a receptor agonist (D(+)-galactose) in these tissues. No attachment of conventional or receptor agents was seen in areas of hepatocellular carcinoma, cholangiocarcinoma, or liver metastases. The studies indicate that in vitro receptor assays are useful in predicting the affinity of new receptor-directed MR imaging contrast agents in human tissue prior to clinical trials.

Multiple factors have been implicated in the hematologic response to erythropoietin (EPO). The authors studied 54 hemodialysis patients; 44 received 1.5 g of iron intravenously, 16 received oral iron for 12 weeks, and 24 were treated with EPO. Some patients received these treatments in sequence. The factors evaluated were serum albumin, protein catabolic rate, serologic evidence of hepatitis B or C, parathormone (PTH), and aluminum levels. Red cell production was expressed as milliliters of red blood cell increase per day per kilogram of body weight. For patients receiving EPO, hematologic response was normalized to 50 U/kg/dialysis. Of the patients on oral iron, 31% had a good response (hematocrit greater than or equal to 30%). Of the patients who received iron intravenously, 50% had a good response (hematocrit greater than or equal to 30%). All patients treated with EPO responded well, except for one patient who did not respond to doses of EPO up to 200 U/kg/dialysis. The response to intravenous iron dextran was more rapid than the response to oral iron or EPO. Nutritional factors (serum albumin and protein catabolic rate), serologic evidence of hepatitis, elevated PTH levels, or elevated aluminum levels did not significantly affect the response to iron supplementation or EPO treatment.

29 patients with diffuse liver disease were examined by ultrasound, CT and MRI. MRI imaging was performed using T1-and t2-weighted spin-echo-sequences and fast gradient-echo-sequences. The paramagnetic contrast agent Gd-DTPA was applied intravenously (0.1 mmol/kg). In all patients with hepatitis MRI enabled exact liver biopsy by delineation of inflammatory changes in cases of chronic or focal hepatitis. CT and ultrasound were superior to MRI in the detection of focal or diffuse fatty degeneration. However, MRI enabled an exact differentiation of fatty changes from neoplasm. In cases of fibrotic changes the most accurate findings could be shown by MRI. In patients suffering from hemochromatosis MRI supplied additional information compared to CT and ultrasound revealing significant reduction of signal intensity due to reinforced enhancement of iron. Concerning Wilson's disease MRI showed a characteristic pattern of parenchymal changes. The application of Gd-DTPA in cases of diffuse liver disease adds supplementary information about perfusion of liver parenchyma, but its value for diagnostic accuracy is only secondary.
