Serum placental phosphatase (heat-stable alkaline phosphatase, HSAP) was measured in the following gravidae with normal weight gain: 71 normal weight normal subjects (NWN), 26 overweight normal subjects (OWN), and 28 underweight normal subjects (UWN); and in the following gravidae with excess gain (XsG), small gain (SmG), or weight loss (WtL): 11 NWN-XsG, seven NWN-SmG, seven OWN-SmG, two OWN-XsG, three OWN-WtL, and five UWN-XsG. The NWN regression equation between 31 and 40 weeks was: Y = 0.66X - 18.44. Overweight subjects' HSAP values were typically below and underweight subjects' values were above the regression line, providing that the weight gain was not less than normal in the overweight group or greater than normal in the underweight group. The average difference from the NWN regression line for each subject was designated "deltaHSAP." The differences between the mean delta HSAP values was statistically significant for: NWN versus OWN, NWN versus UWN, OWN versus UWN, NWN-XsG versus NWN-SmG, NWN-SmG, NWN versus NWN-XsG, and OWN versus OWN-WtL. The higher delta HSAP values were associated with relative caloric insufficiency, the lower values with relative caloric excess. A low degree of inverse correlation was found between infant birthweight and delta HSAP (r = -0.37; P less than 0.002).

We have evaluated the effects of dextrofenfluramine treatment on body weight control during a 90 day period, in obese patients on a calorie-restricted diet. The weight loss in dextrofenfluramine-treated patients was significantly higher than in placebo group. The rate of weight loss was linear up to the end of the trial in d-fenfluramine patients. Neural disturbances (vertigo, headache, depression) were the most frequent side effects observed in both the d-fenfluramine and in the placebo-treated groups, without significant differences between the groups. A total number of 23 patients in the dextrofenfluramine group and 20 patients in the placebo group complained side effects. Six patients (five in the d-fenfluramine group and one in the placebo group) discontinued the treatment, due to the side effects. No modifications of the biochemical parameters considered (fasting blood glucose, bilirubin, alkaline phosphatase, creatinine, blood cell counts, asparate-amino transferase (AST), alanine-amino transferase (ALT), total plasma and HDL cholesterol, and triglycerides) were observed at the end of the trial. A significant reduction of total serum cholesterol was observed in both groups at the end of the period of treatment. In conclusion, dextrafenfluramine was proved to be in short term trials an effective and safe tool in overweight control in obese patients.

A study was carried out in 30 hospitalized diabetics suffering from allergic conditions to assess the effects of ketotifen on various laboratory parameters. Ten of the patients were on diet only, 10 on biguanides plus diet, and 10 on sulphonylureas plus diet. Most were overweight. Patients received 4 mg ketotifen daily for 14 days. Oral glucose tolerance tests and other laboratory investigations were carried out before and 7 and 14 days after the start of ketotifen administration. There were no pathological changes measured in blood levels of sodium, potassium, SGPT, SGOT, alkaline phosphatase, cholesterol, triglycerides, creatinine, uric acid, non-protein nitrogen, haemoglobin, haematocrit, white cell count and differential, and platelet count. Glucose tolerance improved somewhat during the repeated oral glucose tolerance test, and there were no significant changes either in the immunoreactive insulin or growth hormone levels during the test. In the diabetics on biguanides, initial blood pressures were raised both in the lying and standing positions. The levels decreased significantly to normal during ketotifen administration. The results indicate that ketotifen can be used without problems in the treatment of diabetics with allergic disorders and its suggested that a long-term study with ketotifen in diabetic patients could be useful.

Liver morphology and biochemistry were investigated in 61 morbidly obese subjects selected by defined criteria. Median overweight was 82 per cent (range 61 to 170 per cent), and median duration of overweight was 20 years (range two to 45 years). No patient had more than a moderate alcohol consumption and only one was diabetic. Four biopsies (7 per cent) showed normal liver tissue, while fatty change was the main diagnosis in most cases (85 per cent). Increasing degrees of fatty change was significantly (P less than 0.02) associated with presence of lipogranulomas (found in 54 per cent of the biopsies), focal necroses (found in 28 per cent), slight parenchymal inflammation (found in 33 per cent), and Kupffer cell proliferation (found in 49 per cent). Slight portal inflammation was seen in 23 per cent but portal fibrosis in only 2 per cent of the biopsies. No case of cirrhosis was registered. Patients with moderate or severe fatty change, lipogranulomas , focal necroses or with parenchymal inflammation were significantly more obese than patients without these changes (P less than 0.05). Even in absence of fatty change, obese subjects showed a markedly decreased serum albumin concentration and an elevated serum alkaline phosphatase activity (P less than 0.0001) compared with non-obese controls. Serum lactate dehydrogenase and aspartate aminotransferase were significantly raised only in patients with fatty change. With respect to serum bilirubin and plasma cholesterol concentrations no significant differences were detected between patient subgroups and controls.(ABSTRACT TRUNCATED AT 250 WORDS)

We have studied factors affecting biological variation in total plasma alkaline phosphatase in a population of 32 329 apparently healthy subjects four years old or older. Quantification of the bone and liver isoenzymes after thermal denaturation made it possible to specify the contributions of each isoenzyme to variations in the total activities. The main factors that modify plasma alkaline phosphatase activity are age, sex, hormonal state (puberty or menopause), and morphometric parameters (height, body weight, or degree of overweight). The bone isoenzyme is mainly responsible for the variations associated with age, sex, and puberty and to some extent with the menopause. Activity of the liver isoenzyme was also altered at the menopause and by certain drugs, such as oral contraceptives and blood-lipid-lowering agents. These data allow us to propose reference limits for total plasma, bone, and liver alkaline phosphatases according to age and sex.

The effect of long-term voluntary fasting on hematologic variables, biochemical profiles, and liver histologic findings was assessed in 15 obese cats (> 40% overweight). Clinical signs and laboratory results consistent with hepatic lipidosis were observed in 12 of 15 cats after 5 to 7 weeks of fasting, and were associated with 30 to 35% reduction of initial body weight. Histologic examination of successive liver biopsy specimens revealed that obesity was not associated with liver parenchymal lipid accumulation, but that fasting resulted in lipidosis in all 15 cats. The long-term fast was associated with an early (after 2 to 4 weeks of fasting) and significant (P < 0.05) reduction in serum urea, glucose, and albumin concentrations, and RBC mass. Fasting for 5 to 7 weeks was associated with a significant (P < 0.05) increase in hepatic-associated enzyme activities and in total and direct serum bilirubin concentrations. Significant (P < 0.05) changes in serum alkaline phosphatase developed as early as 3 weeks before the onset of hyperbilirubinemia. Except for development of hepatic lipidosis, cats appeared to tolerate the fast without other adverse effect. This study confirmed that long-term fasting may induce clinical hepatic lipidosis in obese cats. Fasting appears to induce a syndrome of hepatic lipidosis that is indistinguishable from feline idiopathic hepatic lipidosis and may be an appropriate model to study the pathophysiologic features and treatment of hepatic lipidosis.

Surgical Eye-camps for cataract treatment of low-income adult Mexicans have been undertaken over the last 10 years. Despite the high prevalence of cataracts among these subjects, no assessment of their nutritional or health status has ever been made. We compare the results obtained for 81 adults (44 men and 37 women) who received treatment in May 1997 with those for a "control" group of age and sex-matched but affluent individuals in Mexico City. alpha-Tocopherol and beta-carotene were assessed and analysed by HPLC and colorimetric procedures, respectively. The plasma tocopherol to cholesterol ratio did not reveal deficiencies of this vitamin, and only 5 patients (2 men and 3 women) had low beta-carotene plasma levels. The patients had high BMI values, with 32% of men and 30% of women overweight, and 2% and 14%, respectively, obese, with higher glucose, cholesterol and triglyceride values reflecting enhanced insulin resistance and lipid abnormalities. The alkaline phosphatase values were elevated suggesting that many of these blind patients are osteomalacic because they now remain indoors. Although it has been suggested that an adequate intake of carotenes and tocopherol are associated with absence of cataract, this appears not to be the case in our study population. Surveys in Mexico have revealed, however, a highly prevalent deficiency of other vitamins such as niacin and riboflavin, both of which have been proved to be protective against cataract. It appears that nutritional deficiencies, obesity, incipient diabetes and lipid disorders co-exist in modern Mexico. We have identified a need for research to aid the design of preventive nutritional approaches at the population level that could be applied in parallel with ongoing surgical treatment.

Weight and gonadal status are the main determinants of bone mass in women. Because of this it is important to study which influences it more. The effect of weight (expressed as body mass index, BMI) and gonadal status of women on total-body bone mineral content (TBBMC) and regional bone mineral content (BMC) was investigated. A total of 373 normal women (mean age 48.9 +/- 13.4 years) were studied: 171 postmenopausal women (mean age 59.3 +/- 9.5 years; years since menopause 11.3 +/- 6.7 years); 76 perimenopausal women (mean age 48.9 +/- 2.2 years); and 126 premenopausal women (mean age 34.7 +/- 7.4 years). In all the women, TBBMC and regional BMC were determined by dual-energy X-ray absorptiometry. Also biochemical markers of bone metabolism (total alkaline phosphatase and tartrate-resistant acid phosphatase) and serum estrone and estradiol were determined. When the women were stratified by gonadal status and BMI, thin women (BMI <20 kg/m2) had significantly lower TBBMC and regional BMC, lower gonadal steroid concentration and higher levels of biochemical markers than overweight (BMI 25-30 kg/m2) and obese (BMI >30 kg/m2) women, regardless of gonadal status. Overweight and obese women had findings suggestive of increased parathyroid activity, but greater bone mass. Weight rather than gonadal steroid concentration is the main determinant of bone mass in women regardless of gonadal status.

An aged, overweight, female cynomolgus macaque (Macaca fascicularis) was diagnosed preliminarily with fatal fasting syndrome based on a history of chronic anorexia, weight loss, hepatomegaly, elevated serum alkaline phosphatase, bilirubinuria, and diffuse increased hepatic echogenicity. Histopathologic examination confirmed the diagnosis of severe hepatic lipidosis. A percutaneous endoscopic gastrotomy (PEG) tube was inserted after a month of orogastric tube feedings failed to stimulate normal appetite. Within 2 weeks of twice daily PEG tube feedings, the animal began to eat voluntarily, and PEG tube feedings were discontinued. The PEG tube was removed without incident. Periodic percutaneous ultrasound-guided hepatic biopsies revealed partial resolution of the hepatic lipidosis during the following 18 months. PEG tube placement should be considered as an alternative treatment to provide nutritional support in macaques with fatal fasting syndrome.

To investigate the associations between obesity and serum hepatic enzyme activities, we measured total body fat (TBF), body mass index (BMI), and hepatic biochemical parameters in 732 apparently healthy adults. TBF was assessed using a body fat analyzer. Serum activities of alanine and aspartate aminotransferase (ALT and AST), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), and lactate dehydrogenase (LD) were determined by standard spectrophotometric methods. Mean activities (+/- SD) of serum ALT and AST in men with high fatness were 51.2 +/- 12.6 U/L and 32.9 +/- 9.2 U/L, which were significantly higher than those in men with low fatness (23.5 +/- 7.4 U/L and 22.5 +/- 7.8 U/L, p < 0.01). Of 147 men with high fatness, 56 (38.1%) had serum ALT levels above the upper limit of normal, whereas only 9.5% (31/328) of men with low or desirable fatness showed elevated serum ALT activities (p < 0.01). Serum ALT, AST, and GGT activities correlated significantly with TBF in both overweight men and women. Among subjects having high TBF, those with fatty liver showed significantly higher incidence of elevated hepatic enzymes, compared to those without fatty liver. In short, elevated serum hepatic enzyme activities are associated with TBF and a high prevalence of fatty liver is observed in subjects with elevated TBF.
