Critical evaluation of methods for determination of body fat content in children: back to basic parameters?

Considering the increasing prevalence of obesity among children and of obesity related disorders in the pediatric population, the reliable evaluation of body fat content in children is of critical importance in research and clinical medicine. In this study, we assessed the congruency of different estimates for body fat content in prepubertal children. We determined anthropometric parameters, such as BMI and skinfold thickness, and bioelectrical impedance in 676 prepubertal Caucasian children. We calculated body fat percentage (BF%) from these parameters applying 5 distinct algorithms and established raw centiles for these models. Expectedly, girls had significantly higher BF% regardless of the method applied. There were, however, significant variances in the calculated amount of BF% between the algorithms, with BIA based equations giving highest BF%, while skinfold based equations tended to provide lower BF% values. Direct comparison of the algorithms revealed a high degree of inconsistency and poor agreement in the assessment of body fat with variations of >10% BF%. Great differences in basic parameters, such as DeltaBMI (3.2 kg/m (2)) or Deltaskinfolds (1.75-fold), would be needed to reliably predict correct ranking of 10% difference in body fat with 95% probability. In summary, BF% strongly varies depending on both the method as well as the algorithm used. This questions the applicability of such field methods for the assessment of BF% for comparative analyses and the superiority of information over basic parameters such as BMI.

Sex-specific effect of the Val1483Ile polymorphism in the fatty acid synthase gene (FAS) on body mass index and lipid profile in Caucasian children.

OBJECTIVE: A Val1483Ile polymorphism in the human fatty acid sythase gene (FAS) has recently been shown to be associated with lower percentage of body fat and substrate oxidation rates in Pima Indians, but its role in other populations has not been described. Here, we investigate the effect of this variant on obesity in Caucasian children and adolescents. SUBJECTS AND METHODS: In total, 738 Caucasian children and adolescents aged 6-17 years of the Leipzig Schoolchildren cohort, which constitutes an unselected representative German population and 205 obese children (body mass index (BMI) 2.71+/-0.04 SDS) were genotyped for genotype-phenotype associations. RESULTS: The frequency of the Ile-allele was lower in German Caucasians compared with Pima Indians (0.03 compared to 0.10). Using generalized linear regression models, there was no effect of the polymorphism on BMI in the whole normal population. However, we identified a significant interaction effect between sex and genotype (P=0.004). Subsequent sex stratified analyses revealed a lower BMI SDS in boys with Ile/Val genotype compared to Val/Val (-0.36+/-0.29 vs 0.09+/-0.05, P<0.05), while an opposite effect was observed in girls (0.48+/-0.19 vs 0.09+/-0.05, P<0.05). In genotype-phenotype associations in obese children, the polymorphism did not affect parameters of insulin, glucose, or lipid metabolism in the whole population. Again, however, obese boys with Ile/Val genotype had significantly higher high-density lipoprotein (HDL) cholesterol levels (1.46+/-0.07 vs 1.23+/-0.03 mmol/l, P<0.05). CONCLUSION: In conclusion, our findings suggest a sex-specific protective effect of the Val1483Ile polymorphism in FAS for obesity in Caucasian boys. In addition, the polymorphism may be associated with a beneficial lipid profile in obese boys.

Metabolic decompensation in children with type 1 diabetes mellitus associated with increased serum levels of the soluble leptin receptor.

OBJECTIVE: Type 1 diabetes mellitus (T1DM) leads to increased serum levels of the soluble leptin receptor (sOB-R) by an as yet unknown cellular mechanism. The aim of our study was to investigate potential metabolic factors that may be associated with the induction of the sOB-R release from its membrane receptor. MATERIALS AND METHODS: Twenty-five children (aged between 1.5 and 17.0 years) were studied at the onset of T1DM. Blood samples were collected before (n = 25), during the first 18 h (mean +/- S.D. 11.1 +/- 4.3 h, n = 16) and 92 h (47.5 +/- 22.5 h; n = 14) after beginning insulin therapy. Serum sOB-R and leptin levels were determined by in-house immunoassays. RESULTS: The sOBR-level and the molar sOB-R/leptin ratio were significantly higher before than after starting insulin treatment (P < 0.05). In contrast, leptin levels were significantly lower (P < 0.05) before insulin therapy. The correlation between sOB-R and blood glucose (r = 0.49; P < 0.05), as well as sOB-R with parameters of ketoacidosis, such as pH (r = -0.72), base excess (r = -0.70), and bicarbonate (r = -0.69) (P < 0.0001) at diagnosis of T1DM remained significant during the first 18 h of insulin treatment. Multiple regression analysis revealed that base excess predicted 41.0% (P < 0.001), age 16.4% (P < 0.05), and height SDS 13.9% (P < 0.01) of the sOB-R variance. CONCLUSIONS: Metabolic decompensation in children with new onset T1DM is associated with dramatic changes of the leptin axis; serum levels of sOB-R are elevated and of leptin are reduced. The molar excess of sOB-R over leptin (median 11.3) in this condition may contribute to leptin insensitivity. Upregulation of the soluble leptin receptor appears to be a basic mechanism to compensate for intracellular substrate deficiency and energy-deprivation state.

[The influence of socio-demographic factors on personality dimensions in the elderly].

The personality factors neuroticism, extraversion, openness for experiences, agreeableness and conscientiousness were investigated in a random population sample of n=497 people over 60 years old with the help of a German version of the NEO Five-Factor Inventory - NEO-FFI (2, 6). The results were compared with those from n=497 people between 18 and 30 years old and with those from n=1051 people between 31 and 60 years old. The elderly described themselves as being less extroverted, less open, more agreeable and more conscientious than the people under 60 years old. Means of the personality factors were not associated with age in the over 60 years old. The average level of neuroticism and conscientiousness was significantly higher in women over 60 years old than in men. People living in the former Eastern Germany were more open and conscientiousness than those living in former Western Germany. A higher level of openness was found in people with a higher educational level. There was a higher level of neuroticism in people living without a partner than in those living with a partner.

Association between G-308A polymorphism of the tumor necrosis factor-alpha gene and 24-hour ambulatory blood pressure values in type 1 diabetic adolescents.

Tumor necrosis factor-alpha (TNF-alpha) is an inflammatory cytokine, which also influences blood pressure (BP). The G-308A polymorphism of the TNF-alpha gene is associated with altered TNF-alpha production. The prevalence of the TNF-alpha-308A allele is reportedly higher among patients with type 1 diabetes mellitus (T1DM) than in the healthy population. In this study we investigated whether this genetic polymorphism might correlate with BP values in diabetic adolescents. Ambulatory BP monitoring (ABPM) was performed in 126 adolescents with T1DM (mean age: 14 +/- 2.4 years). The TNF-alpha G-308A genotype was determined by using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methodologies. ABPM results were related to healthy reference values and are given as standard deviation score (SDS). The prevalence of the -308A allele was higher in diabetic adolescents than the Hungarian reference population (0.26 vs 0.14, p < 0.01). TNF-alpha genotype was associated both with systolic and diastolic BP values (p < 0.01 and p < 0.01, respectively). In patients with TNF-alpha-308GG and -308GA/AA genotypes, the 24-h systolic BP average values were 0.37 +/- 1.33 and -0.38 +/- 1.28 SDS, while 24-h diastolic BP average values were 0.09 +/- 1.30 and -0.67 +/- 1.31 SDS. Hence, the TNF-alpha-308A allele carrier state appears to be associated with lower systolic and diastolic BP values.

[Latent autoimmune diabetes in adults(LADA): part of the clinical spectrum of type-1 diabetes mellitus of autoimmune origin].

According to the most recent classification of diabetes mellitus the latent autoimmune diabetes in adults belongs to the group of type 1 autoimmune diabetes mellitus, as a slowly progressive form. It is not clear whether LADA is a distinct clinical entity or it is a part of the clinical spectrum of type 1 diabetes mellitus. The authors compare the antropologic (body mass index, waist to hip ratio), immunologic (occurrence of islet cell cytoplasmic autoantibodies and autoantibodies against glutamic acid decarboxylase and tyrosin phosphatase), genetic (HLA DR and DQ alleles known to be associated to type 1 diabetes mellitus) characteristics and occurrence of the features of the metabolic syndrome in the groups of type 1 and type 2 diabetes and LADA. 81 type 1 and 190 type 2 diabetics and 38 LADA patients were involved into the study. Freshly diagnosed type 1 diabetics served for controls of the autoantibody study: 48 patients manifested < or = 16 years of age and 89 type 1 diabetics manifested above 16 years of age. The three main diabetic groups differed in age: the average age in the type 1, type 2 and LADA groups were 37, 63 and 58 years respectively. There was no difference among the three groups in gender. The duration of the disease differed significantly between the type 2 and LADA groups (4.0 and 8.0 years respectively). In spite of the shorter duration of the disease in the LADA group, compared to the type 2 diabetics the frequency of insulin dependency was significantly higher in the LADA (81.6%) than in the type 2 group (46.7%). The BMI and WHR were comparable between the type 1 and LADA patients (average values were 23 and 0.83 in type 1 patients and 23.25 and 0.89 in LADA). The type 2 group differed significantly from type 1 and LADA (average values were 29.1 and 0.5). The concentration of glycated hemoglobin was comparable in the three groups. But there was a significant difference in HbA1c concentration between the freshly diagnosed subgroups of type 1 and LADA patients: 10.85% and 8% respectively. The fasting C-peptid levels were significantly higher in the sera of type 2 diabetics (0.75 pmol/l) compared to type 1 (0.2 pmol/l) and LADA patients (0.29 pmol/l). There was a significant difference in C-peptid concentrations between the type 1 and LADA groups, too. The insulin deficiency in LADA seemed to be not as severe as in type 1 diabetes. The serum total cholesterol and triglyceride levels were significantly higher and the HDL cholesterol concentration significantly lower in type 2 diabetics comparing to type 1 and LADA patients and there was no significant difference in this respect between the type 1 and LADA groups. The frequency of occurrence of hypertension differed no significantly between type 2 and LADA, but that of in type 1 diabetes was significantly lower than both type 2 and LADA. The occurrence of multiple autoantibodies (ICA + GADA + anti-IA2) was much more frequent in type 1 diabetes compared to LADA. In the sera of LADA patients the occurrence of ICA and GADA alone or ICA + GADA was characteristic (31.5% - 21.1% - 15.8% respectively). There was no difference between type 1 diabetes and LADA in the occurrence of the alleles of the MHC kown to be associated with type 1 diabetes. The occurrence of the haplotypes HLA DQ2/DR3 and/or DQ8/DR4 was observed in two thirds of type 1 diabetic and LADA patients. Chronic diabetic complications were observed in all of the groups and there was only a secondary connection of the complications with the type of the diabetes. Based on the results the authors suggest that LADA is a part of the clinical spectrum of type 1 diabetes of autoimmune origin.

[Central relationship patterns in comparison with different objects].

In the present study the Relationship Episode Paradigm Interviews of 70 female patients with different psychoneurotic diseases were analysed with respect to object-specific patterns with the CCRT method. The most frequent categories are the same in all relationship episodes and in subsamples of relationship episodes with mother and father. These categories are also predominant in episodes with women and men. Relationship episodes with mother do not differ from episodes with father, and relationship episodes with women are not different from episodes with men. But there are substantial differences in relationship episodes with the mother and women and between episodes with the father and men. Patients recount much more positive relationship patterns with women and men than with their parents. This could be understood as a hint of interpersonal resources.

Experimental cancer cachexia: the role of host-derived cytokines interleukin (IL)-6, IL-12, interferon-gamma, and tumor necrosis factor alpha evaluated in gene knockout, tumor-bearing mice on C57 Bl background and eicosanoid-dependent cachexia.

MCG 101 tumors were implanted sc. on wild-type C57 Bl and gene knockout mice to evaluate the role of host-produced cytokines [interleukin (IL)-6, IL-12, IFNgamma, tumor necrosis factor (TNF) receptor 1, and TNF receptor 2] to explain local tumor growth, anorexia, and carcass weight loss in a well-defined model with experimental cachexia. Indomethacin was provided in the drinking water to explore interactions between host and tumor-derived prostaglandins and proinflammatory cytokines for tumor growth. Wild-type tumor-bearing mice developed cachexia because of rapid tumor growth, which were both attenuated in IL-6 gene knockouts. Similar findings were observed after provision of anti-IL-6 to wild-type tumor-bearing mice. Alterations in food intake were not directly related to systemic IL-6 but rather secondarily to IL-6-dependent tumor growth. The absence of host-derived IL-12, IFN-gamma, or the TNF receptor 1 or receptor 2 gene did not attenuate tumor growth or improve subsequent cachexia. Thus, carcass weight loss was not improved by the omission of host cytokine (TNF-alpha, IL-12, or IFN-gamma) except for IL-6. Systemic indomethacin provision decreased plasma prostaglandin E2 in five of six groups of gene knockout tumor-bearing mice, which was associated with improved carcass weight in these groups. Indomethacin seemed to improve food intake to a similar extent in both wild-type and gene knockouts, which agree with the speculation that eicosanoids are more important to explain anorexia than host cytokines. Our results demonstrate that host- and tumor-derived cytokines and prostaglandins interact with tumor growth and promote cachexia in a more complex fashion than usually presented based on previous information in studies on either anti-cytokine experiments in vivo or on gene knockouts with respect to a "single cytokine model." Overall, host cytokines were quantitatively less important than tumor-derived cytokines to explain net tumor growth, which indirectly explains subsequent cachexia and anorexia.

[Diabetic ketoacidosis in childhood].

Diabetic ketoacidosis is the most serious acute complication of insulin-dependent diabetes mellitus and the most frequent reason for hospital admission of diabetic children. The most frequent cause of death of these patients is also the diabetic ketoacidosis. The mortality rate of the disease has not changed since the seventies (1-2%). In this work, the data of 89 patients with diabetic ketoacidosis were analyzed. These patients were admitted to the 1. Department of Pediatrics of the Semmelweis University of Medicine between 1992-1997. The data (metabolic parameters, the causes of ketoacidosis and the length of hospital stay) of previously known diabetic children was compared with the data of previously unknown diabetic children. Our patients were divided in 2 groups: serious (n = 11), and mild-to-moderate (n = 48) acidosis. Their laboratory findings, their intravenous infusion-, and insulin demand and the length of their hospital stay were compared. The state of consciousness at their hospitalisation and the concomitant complications were also examined. Significant difference was found only in the duration of intravenous insulin administration (with the exception of pH and BE, of course). There was no relationship between the seriousness of the disease and the duration of hospital treatment. It is noteworthy that even the previously known diabetic children with the shortest hospitalization spent more than 7 days at the department.

Combined antioxidant and COMT inhibitor treatment reverses renal abnormalities in diabetic rats.

The development and progression of diabetic nephropathy is dependent on glucose homeostasis and many other contributing factors. In the present study, we examined the effect of nitecapone, an inhibitor of the dopamine-metabolizing enzyme catechol-O-methyl transferase (COMT) and a potent antioxidant, on functional and cellular determinants of renal function in rats with streptozotocin-induced diabetes. Administration of nitecapone to diabetic rats normalized urinary sodium excretion in a manner consistent with the dopamine-dependent inhibition of proximal tubule Na,K-ATPase activity. Hyperfiltration, focal glomerulosclerosis, and albuminuria were also reversed by nitecapone, but in a manner that is more readily attributed to the antioxidant potential of the agent. A pattern of elevated oxidative stress, measured as CuZn superoxide dismutase gene expression and thiobarbituric acid-reactive substance content, was noted in diabetic rats, and both parameters were normalized by nitecapone treatment. In diabetic rats, activation of glomerular protein kinase C (PKC) was confirmed by isoform-specific translocation and Ser23 phosphorylation of the PKC substrate Na,K-ATPase. PKC-dependent changes in Na,K-ATPase phosphorylation were associated with decreased glomerular Na,K-ATPase activity. Nitecapone-treated diabetic rats were protected from these intracellular modifications. The combined results suggest that the COMT-inhibitory and antioxidant properties of nitecapone provide a protective therapy against the development of diabetic nephropathy.

[Critical review of the categorical structures of the core Conflictual Relationship Theme Method (CCRT)].

The CCRT-method developed by Lester Luborsky is the most widespread and best established method to assess relationship structures in the field of psychodynamic psychotherapy research. Although its categorical structures are criticised in many different ways there have not been any attempts to modify them. This article points out the inconsistency of the current categorical system and demonstrates first approaches to alternative solutions. For this purpose genetic algorithms are used. Their application in psychotherapy research is demonstrated here for the first time.

The combined dexamethasone/corticotropin-releasing hormone stimulation test is more closely associated with features of diurnal activity of the hypothalamo-pituitary-adrenocortical system than the dexamethasone suppression test.

BACKGROUND: The dexamethasone suppression test (DST) is a widely used endocrine test in psychiatry, but was reported to not allow reliable inferences with regard to the basal activity of the hypothalamo-pituitary-adrenocortical (HPA) system. We compared the association of the standard DST and the combined dexamethasone/corticotropin-releasing hormone (DEX/CRH) challenge with parameters of diurnal cortisol profiles. METHODS: We performed a DEX/CRH challenge and 24-hour cortisol profiles in 25 depressed patients (mean age: 47.4 +/- 16.0 years) and 33 age-matched healthy controls (mean age: 51.4 +/- 19.3 years). RESULTS: A path analysis showed cortisol area under the curve (AUC) after CRH (= DEX/CRH status) to be dependent upon minimal 24-hour cortisol and evening frequency of pulsatile cortisol release. In contrast, postdexamethasone cortisol (= DST status) was related to 24-hour mean cortisol. Simple linear regressions supported an association of cortisol AUC with several parameters of the diurnal cortisol profiles, which was not true for the standard DST. CONCLUSIONS: We conclude that the combined DEX/CRH challenge test is more closely associated with the activity of the HPA system than the standard DST in healthy and depressed subjects.

Reproducibility of erythrocyte sodium-lithium countertransport activity and ambulatory blood pressure measurements in type 1 diabetes mellitus.

We aimed to study the reproducibility of sodium-lithium countertransport [SLCT] activity and ambulatory blood pressure monitoring [ABPM] in type 1 diabetes. We did this by performing repeated measurements of SLCT activity and ABPM in 11 recent-onset diabetic children and in 11 patients with longer duration of diabetes. Both parameters were related to microalbuminuria. In the older group of diabetic children a significant correlation [r = 0.78; P<0.005] in SLCT activity between the first and second study was observed [514.3+/-186.4 vs 491.0+/-148.0 micromol/l erythrocytes/h]. Diurnal systolic and diastolic blood pressure were comparable at both time points within the same group of diabetic children [in group 1: 102.6+/-6.1 vs 108.6+/-7.6 mmHg N.S.; in group 2: 113.4+/-10.6 vs 114.0+/-7.8 mmHg N.S. Diastolic blood pressure in group 1: 57.4+/-4.8 vs 65.7+/-6.9 mmHg N.S., in group 2: 70.6+/-9.1 vs 68.5+/-5.3 mmHg N.S.]. Moreover, there was a significant correlation in both diurnal and nocturnal systolic blood pressure between the first and second study in the whole diabetic population. Both SLCT activity and blood pressure values obtained by ABPM were found to be reproducible individual characteristic markers in type 1 diabetic children.

Endurance training and its effect upon the activity of the GH-IGFs system in the elderly.

There is an age-associated decline in the activity of the GH-IGFs system. However, so far, it has not been studied, whether this decline in somatotrophic activity might be preventable by intensive exercising. We studied 11 elderly male (50-78 years) marathon runners and 10 age-matched male (52-73 years) sedentary controls to evaluate plasma concentrations of GH, total and free IGF-I and IGF-II and of IGF-binding protein-1 (IGFBP-1), IGFBP-2, IGFBP-3 and insulin. When comparing the two groups (runners vs controls) no differences were found in GH (1.0 +/- 1.2 vs 1.3 +/- 1.3 microg/l [mean +/- SD]), IGF-1 (115 +/- 23 vs 113 +/- 21 microg/l), IGF-II (961 +/- 192 vs 864 +/- 125 microg/l), free IGF-1 (227 +/- 80 vs 318 +/- 146 ng/l), free IGF-II (563 +/- 249 vs 492 +/- 108 ng/l), IGFBP-3 (2403 +/- 515 vs 2307 +/- 326 microg/l) or insulin (26 +/- 13 vs 27 +/- 18 mU/l). However, IGFBP-1 (4.44 +/- 2.61 vs 2.28 +/- 0.93 microg/l) and IGFBP-2 (493 +/- 143 vs 340 +/- 186 microg/l) were found to be significantly increased in marathon runners. In conclusion, our findings do not support the hypothesis that the age-associated decline in GH, IGF-1 and IGFBP-3 may be preventable by intensive endurance training. However, marathon running affects the regulation of the GH-IGFs system activity at the level of IGFBP-1 and -BP-2.

Rapid development of glomerulosclerosis in diabetic Dahl salt-sensitive rats.

Diabetic nephropathy tends to develop more readily in patients with a family history of hypertension and/or disturbances in sodium transport across the plasma membrane. This prompted us to study the renal effects of diabetes mellitus in a rat strain which is predisposed to develop salt-sensitive hypertension, the Dahl salt-sensitive rat. Diabetes is associated with several aberrations in the renal handling of sodium, such as elevation of tubular Na+, K+ATPase activity. This effect was more pronounced in Dahl salt-sensitive than in Dahl salt-resistant rats. Severe renal lesions, characteristic of the advanced phase of diabetic nephropathy are very rarely observed in rats with streptozotocin diabetes. However, 2 months after induction of diabetes, the Dahl salt-sensitive rats had morphological signs of advanced glomerular disease. The urinary albumin concentration was very high, but did not correlate with the blood pressure. Non-diabetic Dahl salt-sensitive rats as well as Dahl salt-resistant diabetic and non-diabetic rats had little or no signs of glomerular disease and consistently very low urinary albumin concentrations.

With aging in humans the activity of the hypothalamus-pituitary-adrenal system increases and its diurnal amplitude flattens.

There is compelling evidence for feedback disturbances in the hypothalamus-pituitary-adrenal system associated with human aging as assessed by challenge tests. However, reports about age-related changes in human basal activity are ambiguous and to date little is known about changes in the pulsatile features of the HPA system. To investigate these changes we studied twenty-two healthy male and eleven healthy female subjects ranging from 23 to 85 and 24 to 81 years respectively. 24-hour blood sampling with 30 minute sampling intervals was performed. From 18.00 to 24.00 hours blood was sampled every 10 minutes for analysis of pulsatile features of HPA activity. Statistical analysis revealed that age in particular had major effects upon basal HPA-system activity: there was a significant age-associated increase in minimal (p < 0.0001) and mean (p < 0.02) cortisol plasma concentrations, but no alteration in pulsatile features. We found no age-cortisol correlation during daytime, but were able to demonstrate a strong impact of age upon cortisol plasma levels from 20.00 to 1.30 hours. The diurnal amplitude of cortisol (p < 0.005) and ACTH (p < 0.006), relative to the 24-hour mean of the hormones, showed an age-associated decline. Additionally, the evening cortisol quiescent period (p < 0.01) was shortened in the elderly, suggesting increasingly impaired circadian function in aging. Our results suggest an increased basal activity and a flattened diurnal amplitude of the HPA system in the elderly.

Insulin-like growth factor-I (IGF-I) plasma concentrations are increased in depressed patients.

There is some evidence that the somatotrophic system in depression, as assessed by basal growth hormone (GH) concentrations and by GH releasing hormone (GHRH) challenge, might be dysfunctional. However, the rather limited data have been inconclusive so far and plasma concentrations of both insulin-like growth factor-1 (IGF-I) and binding proteins (IGFBP 1 to IGFBP-6) have not been measured simultaneously in depressed patients. We studied 24 severely depressed patients and 33 healthy controls and estimated 24-hour mean plasma cortisol, six-hour evening mean plasma growth hormone (GH), morning plasma IGF-I, IGFBP 2 and 3 and GH-binding protein (GH-BP). Twenty-four-hour mean cortisol (306 +/- 69 vs. 196 +/- 30 nmol/l, p < .001) and IGF-I (157 +/- 40 vs. 120 +/- 33 micrograms/l, p < .01) plasma concentrations were found to be significantly increased in depressed patients, while there was no difference in GH or binding proteins between both groups. MANOVA analysis revealed age and diagnosis to have main effects upon plasma IGF-I. Especially young age and a diagnosis of major depression are associated with higher plasma IGF-I. After treatment only patients in remission had attenuated IGF-I plasma concentrations. We conclude that plasma IGF-I is increased in acutely depressed patients similar to other states of hypercortisolemia.
