In 110 children-between 0-16 years of age-, 90 children with Down-syndrome and 20 controls the following metabolic parameter were analyzed: ETK (vitamin-B1-activating coefficient), EGR (vitamin B2), P-5'-P, EGOT (vitamin B6), GOT, GPT, pH, K, Na, Ca, Cl, uric-acid (HS). Among some important correlations between the different parameters it could be demonstrated-for the first time to our knowledge-that in Mongoloids a disturbance of the vitamin-B1-metabolism exists, certified by the so-called transketolase-test.

Twenty obese and 20 lean LA/N-cp male rats and 20 male Sprague-Dawley rats were fed a diet containing either 54 percent sucrose or starch for six weeks. After a 14-16 hour fast, rats were killed. Liver and kidney enzyme activities were determined in the LA/N-cp rats while plasma urea and selected amino acids were determined in all rats. Liver glucose-6-phosphatase (G6PASE), fructose-1,6-bisphosphatase (FBPASE), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphate dehydrogenase (G6PDH), 6-phosphogluconate dehydrogenase (6PGDH), malic enzyme (ME), glucokinase (GK), pyruvate kinase (PK), phosphofructokinase (PFK), glutamic-oxaloacetic-transaminase (GOT), glutamic-pyruvic transaminase (GPT), arginase (ARGASE), arginine-synthase (ARG-SYN) and ornithine transcarbamylase (OTC) levels were significantly affected by phenotype (obese greater than lean). All the above changes in enzyme levels were exaggerated by sucrose-feeding with the exception of PK, PFK, GOT, GPT, ARGASE and ARG-SYN. Kidney cortex G6PASE, PEPCK and ARGASE activities were higher in the obese rats as compared to the lean littermates. Sucrose feeding resulted in higher cortex G6PASE, FBPASE and PEPCK as compared to starch-fed rats. A phenotype effect was noted with plasma glutamate, urea, leucine, isoleucine and valine (obese greater than lean) and a diet effect was seen with aspartate, phenylalanine, leucine and valine (sucrose greater than starch) concentration. Sprague-Dawley rats had higher plasma urea and lower alanine than lean LA/N-cp males. Metabolic obesity in the LA/N-cp rat appears to involve an elevated capacity for pathways of glycolysis, gluconeogensis, lipogenesis and amino acid catabolism in the liver.

A total of 166 volunteers for an AIDS vaccine study (Vaxsyn, baculovirus produced recombinant GP160; MicroGeneSys Inc, West Haven, Connecticut, USA) were interviewed and examined. Blood was collected for routine laboratory testing as well as T-cell counts, HIV ELISA (EIA), Western blot (WB) and p24 Ag. Eighty-five men (mean age 22.2 years, range 18-42) and 81 women (mean age 23.9 years, range 17-50) volunteered; 130/166 (78%) were university students. Most had learned of the study from news media (55%), friends or workplace (37%). The most common causes for exclusion were the presence of indeterminate WB (26.5%) or a change of mind after the initial interview (24%). Other causes were abnormal cell count and differential (7.2%), elevated alanine aminotransferase (3.6%), positive hepatitis B antibody (3.6%), abnormal urinalysis (3.4%), recent venereal disease (3.0%), T4 cell count less than 400 (1.9%), abnormal chest X-ray (1.7%), recognized high-risk behaviour (1.7%), multiple sex partners (1.2%), positive rapid plasma reagin test (1.2%), failure to meet age criteria (1.2%), unable to be available for entire study (1.2%), abnormal physical examination (0.6%) and positive p24 Ag (0.6%). No volunteers had positive EIA, but 14.5% had more than one reason for exclusion. Even in a community with low prevalence for HIV, a large majority of healthy heterosexual volunteers can be expected to be ineligible for enrollment in HIV vaccine trials. An average of 4.8 volunteers were screened for each of 12 vaccinees chosen.

A 32-year-old male (Mr. A.), monitored during an 8-d heat acclimation (HA) investigation, unexpectedly exhibited heat intolerance and heat exhaustion. Thirteen other males completed HA without indications of either heat intolerance or heat exhaustion. Because Mr. A. responded normally to HA on days 1-4, the intervention of an unknown host factor on days 5-8 was suggested. Mr. A.'s heat exhaustion episode (day 8) was apparently forewarned by loss of body weight and increased delta HR, delta Tsk (days 5-8) and delta Tre (days 7-8) during daily 90-min trials. His symptoms indicated classical salt depletion heat exhaustion, but the calculated salt deficit (less than 0.1 g NaCl.kg-1 body weight) was mild. Post-heat exhaustion serum enzyme levels were either normal (ALT, AST) or acutely elevated (CPK). Blood beta-endorphin and cortisol levels were six times and two times greater than control values, respectively. This case report is unique because clinical/physiological measurements and blood analyses were performed before, during, and after heat intolerance and heat exhaustion.

With respect to liver disease, the primary function of the laboratory is to identify its presence. Tests are not available that permit a specific diagnosis and an accurate prognosis. Several tests should be present in a minimum data base that can help identify hepatobiliary disease. They are ALT, SAP, total serum bilirubin, urine bilirubin, cholesterol, albumin, BUN, glucose, red cell morphology, and urine sediment. It is sometimes possible to tentatively identify whether a disease is primarily hepatocellular or biliary from the pattern of changes that occur in these tests. In addition, an estimate of the severity is sometimes possible when abnormal values are extreme. The keys are to avoid overinterpretation, use serial evaluations, and rely on a liver biopsy when definitive answers are needed. If liver disease is suspected but there are only marginal changes in the routine tests, the more sensitive tests of function, BSP retention and ammonia tolerance, are warranted. In the future, as more knowledge is gained about the responses of ARG, GGT, and ICG retention to naturally occurring diseases, these tests may join or replace some of those currently used. Also, as the ability to accurately and economically measure the various bile acids improves, a sensitive, yet noninvasive, method to detect and define modest changes in hepatobiliary function may result.

Reporting of hepatitis B is not compulsory in France, but it is estimated that 8500-9000 acute cases and 100,000 hepatitis B infections occur every year. Seroprevalence studies have been carried out in selected populations. Every blood donation is screened for HBsAg, alanine aminotransferase elevation and anti-HBc antibody. Prevalence of HBsAg has declined from 13.9 positive donations in 1986 per 10,000 to 5.3 in 1991. In pregnant women, overall seroprevalence is estimated at 0.8-1%, which represents more than 5000 children born each year to carrier mothers. Screening of HBsAg for all women when six months pregnant is now compulsory. Heterosexual patients at STD clinics were shown to have a very high risk of being infected with hepatitis B virus, with a chronic carrier rate of 4-5%. In hospital employees before the introduction of vaccination, the overall incidence of hepatitis B was 100-300 acute cases per 100,000 employees per year. Risk varied according to exposure to blood; the highest incidence was found in nurses in dialysis wards. Vaccination against hepatitis B is now compulsory for all hospital and laboratory workers and medical and paramedical students. In preventive medicine consultants, routine medical check-up showed an overall HBV prevalence of 2.2% and a carrier rate of 0.3% in men and 0.1% in women. Immunization of all newborns and adolescents has recently been adopted in France, vaccination at school of adolescents aged 10-11 years being the main target.

Donor lymphocyte infusions (DLI) were given between June 1990 and March 1996 to 18 patients with chronic myeloid leukemia (CML) for the treatment of cytogenetic (n = 6) or hematologic relapse (n = 12) following an allogeneic bone marrow transplant (BMT). Patients were divided in two groups: patients in group A (n = 8) received a large dose of donor lymphocytes (> or = 1 x 10(8)/kg), whereas patients in group B (n = 10) received escalating numbers of cells (2 x 10(5) up to 2 x 10(8)/kg). The median number of DLI in group A was 2 (range 1-3); the median number of infusions in group B was 7 (range 3-9). Acute GVHD occurred in 12 patients (grades I-III) and was a major cause of death in two. The risk of developing GVHD correlated with the number of cells infused: 37%, 14%, 5% and 0% for DLI with cells > or = 1 x 10(8), 2 x 10(7)/kg, 2 x 10(6)/kg, and 2 x 10(5)/kg, respectively (P = 0.01). Median transaminase levels were found to be significantly increased in patients with, as compared to patients without, acute GVHD (GPT 412 vs 28 IU/l; P = 0.03). Severe aplasia occurred in four and was a contributing cause of death in two patients. Overall, four patients died as a consequence of DLI and all received > 1 x 10(8)/kg cells: the actuarial risk was 38% in group A and 14% in group B (P = 0.1). There were 10 complete and three partial cytogenetic responses: the actuarial probability at 5 years of being Ph negative was 69%: it was 46% for group A and 85% for group B (P = 0.1). The longest patient is now 6 years post-DLI, Ph negative, BCR-ABL negative. The actuarial 3 year survival is 38% in group A and 86% in group B (P = 0.06). The study confirms that DLI post-BMT is not innocuous and that there is a definite long-lasting antileukemic effect in patients with CML. It also suggests that: (1) the risk of developing GVHD correlates with the number of infused cells; (2) that significant elevations of serum GPT levels are associated with GVHD; and (3) that the use of escalating doses of cells may allow the identification of side-effects and discontinuation of infusions before life-threatening GVHD has developed.

In each of two experiments, rats were pre-exposed to two flavoured solutions, saline-lemon and sucrose-lemon. For group ALT, trials with one solution alternated with trials with the other. Group BLK received all trials with one solution in a block, before any trials with the other. An associative theory suggests that the alternating, but not the blocked, schedule would establish an inhibitory association between sucrose and saline. To provide a retardation test of this inhibition, some animals in each group were then given a single pairing of saline and sucrose, experienced sodium depletion, and were finally tested for their consumption of sucrose. Sodium depletion increased consumption of sucrose more in group BLK than in group ALT. In groups given no saline-sucrose pairing, sodium depletion had only a small effect on sucrose consumption, which was the same in both groups. After multiple pairings of saline and sucrose, sodium depletion had an equally large effect on sucrose consumption in both ALT and BLK groups. These results imply that alternating pre-exposure to two compound solutions does establish an inhibitory association between their unique elements, and thus provide support for an associative theory of perceptual learning.

Rats were exposed to two compound solutions, saline-lemon and sucrose-lemon. In Group ALT, trials with one solution alternated with trials with the other. Group BLK received all trials with one solution before any trials with the other. Previous retardation tests had implied that only alternating exposure would establish sucrose as an inhibitor of saline. To provide a complementary summation test for this inhibition, in Experiment 1, all the animals received pairings of peppermint and saline and were tested for consumption of peppermint-sucrose under sodium depletion. Consumption was increased by sodium depletion only in Group BLK. In Experiment 2, a retardation test was used to show that presentation of saline-lemon before sucrose-lemon on each exposure day would establish sucrose as an inhibitor of saline. Neither exposure to sucrose-lemon before saline-lemon nor alternating exposure to sucrose and saline alone had the same effect. These results provide support for an associative theory of perceptual learning that suggests that exposure to complex stimuli aids later discrimination partially as a result of establishing inhibitory associations between their unique elements.

We examined the risk and determinants of developing severe liver toxicity in 108 HIV-infected patients showing adherence to nevirapine- and efavirenz-containing regimens. Between January 1997 and December 2000, 70 patients were treated with nevirapine- and 38 patients with efavirenz-containing regimens, for a median period of 127 days (interquartile range 65-240). Severe liver toxicity was defined as grade 3-4 elevations (>5 x upper limit of normal) of aminotransferases AST or ALT. A total of 22 (20%) patients showed severe liver toxicity, 17 of them were treated with nevirapine- and five with efavirenz-containing regimens (relative risk [RR]: 1.85, 95% confidence intervals [CIs] 0.74-4.61; P=not significant). Multivariate analysis showed the association of severe liver toxicity with hepatitis C antibody positive (RR 7.64; 95% CI: 1.48-39.52; P=0.01), nevirapine- or efavirenz-containing regimens combined with a protease inhibitor (RR: 3.07, 95% CI: 1.01-9.32, P=0.04) and alcohol intake greater than 40 g per day (RR: 3.09, 95% CI: 1.27-7.54, P=0.01). These findings have potential implications for selecting and monitoring antiretroviral therapy in HIV-infected patients with hepatitis C virus coinfection and for avoiding alcohol intake during antiretroviral therapy.
