A case of the clear cell variant of hepatocellular carcinoma with an abundant myxoid stroma is presented. The tumor occurred in a 55-year-old Japanese man, and swelling of the scrotum was the initial symptom. The patient underwent high-level orchiectomy, and the pathologic diagnosis was a metastatic tumor on the surface of the processus vaginalis and intact testis. Extensive examination failed to show a primary site. Subsequent autopsy revealed a large hepatic tumor and metastatic nodules with a prominent myxoid appearance in multiple organs. Histologically, each tumor consisted of uniform small tumor cells with clear cytoplasm attributed to abundant accumulation of glycogen particles, and an abundant myxoid stroma was also present. The tumor cells were positive for keratin, alpha 1-antitrypsin, alpha 1-antichymotrypsin, liver ferritin, prealbumin, and fibrinogen, but lacked alpha-fetoprotein. These findings indicated that this case was hepatocellular carcinoma of the clear cell type with a prominent myxoid stroma.

To determine the ability of intraoperative hypothermia to modify changes in the plasma protein component of the acute-phase response (APR) and the plasma hormone component of the endocrine response (ER) to surgical injury, 20 patients undergoing coronary artery surgery were randomised to an intraoperative blood temperature of 28 degrees C or 20 degrees C during cardiopulmonary bypass (CPB). Serial measurements of pack-cell-volume corrected concentrations (PCVCC) of five plasma proteins (albumin, prealbumin, transferrin, caeruloplasmin, ferritin) and six plasma hormones (adrenaline, noradrenaline, cortisol, triiodothyronine, thyroxine, and thyroid-stimulating hormone) were obtained twice preoperatively, seven times during surgery, six times in the 24 hours following surgery, and a further four times until the seventh postoperative day. A more profound level of intraoperative hypothermia significantly reduced the plasma adrenaline response to CPB but not the other components of the ER or APR.

Serum ferritin, prealbumin, pseudocholinesterase, alpha-1-antitrypsin and caeruloplasmin were determined in control subjects and patients with pancreatic cancer, chronic pancreatitis or extra-pancreatic disease mainly of gastrointestinal origin, in order to investigate the different hepatic changes which influence serum ferritin in chronic pancreatic and other digestive diseases. Increased circulating ferritin was found in pancreatic cancer and extra-pancreatic disease when compared to controls. Correlations were detected between ferritin and the other proteins investigated and between ferritin and total bilirubin, alkaline phosphatase and alanine aminotransferase. Multiple regression analysis demonstrated that cholestasis accounts for 45% of circulating ferritin, the acute-phase response accounted for 18% and decreased liver function accounted for 11%. We conclude that the increase in serum ferritin in chronic pancreatic and other gastrointestinal diseases largely depends on liver changes, with cholestasis probably playing a primary role.

Plasma levels of retinol binding protein (RBP), prealbumin, total protein, albumin, transferrin and ferritin were estimated in three groups of diabetic patients seen at a diabetes centre in S. India. The groups consisted of patients with fibrocalculous pancreatic diabetes (FCPD), non-insulin-dependent diabetes mellitus (NIDDM) and insulin-dependent diabetes mellitus (IDDM). Mean RBP levels were lower in FCPD and IDDM patients compared to controls but this did not reach statistical significance. Prealbumin levels were normal in FCPD patients, but low in IDDM compared to controls (P less than 0.005) and NIDDM (P less than 0.05). FCPD patients had lower transferrin levels compared to controls (P less than 0.05). There were no differences in the levels of total protein, albumin and ferritin in any of the study groups. The study shows that biochemical evidence of undernutrition is seen in FCPD and IDDM patients while NIDDM patients are not significantly different from non-diabetic control subjects.

Hepatoid adenocarcinomas of the stomach are gastric carcinomas with both adenocarcinomatous and hepatocellular differentiations. They usually produce large amounts of alpha-fetoprotein (AFP) with a Concanavalin A-binding property of hepatic type. In this study, these carcinomas occurred in older persons, with the antrum being a common site. Observed grossly, growth of the tumors was nodular and massive. Prognosis was poor because of frequent liver metastases. In the cytoplasms of tumor cells, various serum proteins were identified, including AFP, alpha-1 antitrypsin (AAT), alpha-1 antichymotrypsin (ACT), albumin, and prealbumin. Localizations of ferritin, prothrombin, and transferrin were demonstrated with less frequency. Adenocarcinomatous foci were composed of well-differentiated, intestinal-type epithelial cells and often contained carcinoembryonic antigen. These adenocarcinomatous and hepatoid areas were often intermingled with each other. There were extensive venous involvements by tumor cells. The poor prognosis of the tumors may be attributed to these involvements as well as to production of AFP and presence of AAT/ACT, which have immunosuppressive and protease-inhibitory properties, respectively.

We have compared the nutritional status of patients with lepromatous leprosy coinfected with pulmonary tuberculosis (18 cases) with that of lepromatous leprosy (239 cases) and of pulmonary tuberculosis (21 cases) and with that of healthy controls. There was a severe weight loss and reduction of skinfold thickness in the patients with pulmonary tuberculosis as well as in lepromatous patients with associated pulmonary tuberculosis, but not in patients with lepromatous leprosy. Levels in sera of diet-dependent proteins, such as albumin, prealbumin and retinol binding protein, were significantly decreased in all three groups of patients; on the other hand, levels of the diet-independent proteins, such as the immunoglobulins, were raised in all the groups, particularly in the pulmonary tuberculosis patients as compared with healthy controls. Serum transferrin levels were decreased only in the tuberculosis patients with or without lepromatous leprosy, but not in patients with leprosy alone. While haemoglobin levels decreased in all patient groups, serum iron concentrations were reduced most in lepromatous patients concomitantly infected with pulmonary tuberculosis. Serum ferritin levels increased in the sera of pulmonary tuberculosis and lepromatous leprosy patients, but was severely reduced in lepromatous patients with associated pulmonary tuberculosis. Mean serum zinc and calcium levels were decreased in all three groups of patients, while the serum copper concentration was increased in all of them compared with healthy controls. Also, inorganic phosphorus was elevated in tuberculosis and lepromatous patients coinfected with pulmonary tuberculosis, but not in lepromatous patients. Serum calcitonin levels were increased in all patient groups indicating an inverse correlation between serum calcium and calcitonin levels. This is the first comparative report describing the status of macro- and micronutrients in two most important mycobacterial diseases of the third world countries.

Routine clinical chemical variables and parameters of the vitamin, iron and zinc status were measured in 20 female patients with anorexia nervosa (AN) and in 10 lean and 10 normal weight, healthy, female control subjects. Patients with AN had higher activities of L-gamma-glutamyl transferase (gamma-GT) and glutamate pyruvate transaminase (SGPT) and a higher concentration of prealbumin in serum and lower leucocyte and lymphocyte counts in blood. For the other routine clinical chemical parameters no significant differences between the groups were observed. AN patients had higher serum vitamin B12 and retinol levels. No significant differences were found for the status parameters of thiamin, vitamin B6, vitamin C, folate, vitamin E and vitamin D. Contradictory results were obtained for the riboflavin status: AN patients had a lower level of flavin adenine dinucleotide (FAD) in blood and a lower stimulation ratio of the glutathione reductase activity in erythrocytes (alpha-EGR). Patients with AN had higher serum ferritin concentration and lower total iron binding capacity (TIBC). However, haemoglobin (Hb), haematocrit (Ht) and iron saturation were not significantly different. No significant difference was found in the concentration of zinc in plasma. In spite of the poor intake of nutrients and energy, the results obtained did not indicate an inadequate status of vitamins, iron and zinc in patients with AN.

The nutritional status of an unselected group of 111 children from the village of Bouansa, People's Republic of the Congo, was studied. Comprehensive clinical examinations, anthropometrical measurements and analysis of albumin, prealbumin, ferritin, C-reactive protein (CRP), IgA, IgG, IgM, IgE, IgG- and IgM-circulating immune complexes (CIC) were carried out. The results show, by anthropometrical classification, a high prevalence of moderate malnutrition. Low levels of plasma proteins and high levels of immunoglobulins and CIC were found. No correlation between anthropometrical classification and plasma proteins was established. Children with increased levels of CRP showed low prealbumin values and increased levels of ferritin. Patterns of immunoglobulins and CIC were close to those found in other studies in tropical countries. To evaluate the anthropometrical and biochemical findings it is necessary to take into consideration the apparently healthy appearance of the children, which shows the degree of adaptation to the limited availability of food and the high rate of acute and chronic infections.

Age- and sex-specific reference intervals based on the 0.025 and 0.975 fractiles of data derived from a healthy pediatric population are presented for zinc, copper, selenium, iron, ferritin, retinol, alpha-tocopherol, and related analytes in serum. Age was an important covariate for copper, selenium, retinol, and tocopherol, and ferritin in boys. Strong correlations were found between retinol and retinol-binding protein, prealbumin (transthyretin), alpha-tocopherol, and selenium. Tocopherol was highly correlated with both cholesterol and triglycerides. We found no relationship between serum zinc and either retinol or retinol-binding protein. Despite exclusion of children in whom anemia, microcytosis, or variant hemoglobins were found, the 0.025 fractile for iron in several age groups was even less than the concentration considered to indicate poor iron nutritional status.

We assessed the nutritional status of 302 menstruating women living in three urban, semi-rural and rural areas of eastern Algeria. The anthropometric data and the biochemical measurements (serum levels of total proteins, albumin, transferrin and prealbumin) have shown the absence of protein malnutrition and the evidence of problems of overweight, whatever the criterion used (body mass index or relative weight). There were no differences according to the residence. Anemia (defined by WHO references) was observed in 28% of urban women, 19% of semi-rural women and in 32% of rural women. Iron deficiency (defined by the association of serum ferritin level of 12 micrograms/l or less and transferrin saturation less than 15%) was observed in 29, 27 and 22% of the cases, respectively. Folate deficiency (defined by concentration of red blood cell folates of less than 100 micrograms/l) was observed in 48, 45 and 22% of cases, respectively. Finally, 81% of anemia were associated with biochemical evidence of iron and/or folate deficiency.
