To extend the method we also established PCR-based rapid genotyping protocols for Beijing, East-African-Indian and U lineages. (C) 2009 Elsevier B.V. All rights reserved.”
“Background: Drug-induced bodyweight gain (BWG)

is a serious concern in pharmacotherapy with second-generation antipsychotics. The interindividual variability is likely to be modulated by genetic factors. In the past, pharmacogenetic studies yielded conflicting results, and none of the identified genetic alterations exerts sufficient predictive value for this severe side effect of psychopharmacotherapy. Aim: We aimed to contribute to the replication and extension of prior association findings and investigated the genes Adavosertib supplier encoding serotonin 2C receptor (HTR2C), insulin-induced gene 2 (INSIG2) and leptin (LEP). Patients & methods: We investigated the association of HTR2C, LEP and INSIG2 SNPs with antipsychotic-induced BWG in 128 German schizophrenic patients. Genotyping was performed for nine SNPs (HTR2C: rs498207, rs3813928, rs6318 and rs3813929; INSIG2: rs17587100, rs10490624, rs17047764 and rs7566605; LEP: rs7799039). Association analysis included logistic regression analysis

and Pearson’s chi(2) tests. Results: We report a significant association of three HTR2C SNPs (rs498207, rs3813928 and rs3813929) and of the respective haplotype with antipsychotic-induced BWG. Regarding the X-chromosomal SNP rs498207, individuals with AA/A genotype gained more weight than those with GG/G genotype. The association observed with the SNP rs498207 was also significant after correcting for multiple testing (p = 0.0196). No association was found for INSIG2 Selleck Combretastatin A4 and LEP SNPs. Conclusion: The results contribute to the accumulating

evidence for an association of the X-chromosomal HTR2C gene with antipsychotic-induced BWG. The proposed underlying mechanisms include decreased HTR2C gene expression with reduced 5-HT-modulated activation of hypothalamic proopiomelanocortin-neurons, and inverse 5-HT(2C) agonism in the presence of D(2) receptor antagonism.”
“Context: More than 50% of Americans use dietary supplements, and 60-70% fail to report this use to their physicians. Intoxication from vitamin D supplements has been rarely reported but may now occur more frequently. This may be attributable to an increase learn more in vitamin D supplement intake due to the findings that deficiency is common and has been associated with a number of disease states.\n\nObjective: We report two cases of vitamin D intoxication with dietary supplements made in the United States caused by manufacturing and labeling errors.\n\nMethods: Case histories were obtained, and serial laboratory data (calcium and vitamin D metabolites) were measured. Each dietary supplement was analyzed by UV spectrophotometry followed by HPLC.\n\nResults: In both cases, repetitive inquiries were required to elicit the use of dietary supplements.
