OBJECTIVE Mesenteric fat hyperplasia is a hallmark of Crohn's disease (CD), and C reactive protein (CRP) is correlated with disease activity. The authors investigated whether mesenteric adipocytes may be a source of CRP in CD and whether inflammatory and bacterial triggers may stimulate its production by adipocytes. DESIGN CRP expression in the mesenteric(More)
To determine whether the size of the intestinal bifidobacterial population can influence the immune response to poliovirus vaccination in infants, we set up a randomized, placebo-controlled trial. From birth to 4 mo, infants were given a fermented infant formula (FIF) or a standard formula (placebo). Bifidobacteria were quantified monthly in infant stools.(More)
The identification of mutations in the MEN1 gene causing MEN1 has represented a challenge since the cloning of the gene in 1997 because of the lack of mutation hot-spots in the gene and the lack of phenotype-genotype correlations. The use of denaturing high performance liquid chromatography (DHPLC), a high throughput, reliable and automated(More)
Multiple endocrine neoplasia syndrome type 1 (MEN1), which is secondary to mutation of the MEN1 gene, is a rare autosomal-dominant disease that predisposes mutation carriers to endocrine tumors. Although genotype-phenotype studies have so far failed to identify any statistical correlations, some families harbor recurrent tumor patterns. The function of(More)
Three multiplex polymerase chain reactions (PCRs) targeted on Bifidobacterium and related species were designed to identify human species. The selected primers yielded amplified products of various sizes, each specific for a species. Three to four pairs were gathered in one PCR reaction and their specificity under multiplex conditions was confirmed using(More)
For facilitated genotypic analysis of multiple endocrine neoplasia type 1 (MEN1), a familial syndrome associated with tumors of the parathyroid and neuroendocrine tissues, we developed two screening methods, heteroduplex mutation assay (HMA) and mutation detection gel analysis (MDGA), both based on electrophoretic discrimination of polymerase chain reaction(More)
CONTEXT Hyperparathyroidism-jaw tumor syndrome (HPT-JT) is an autosomal dominant syndrome with incomplete penetrance that can associate in a single patient parathyroid adenoma or carcinoma, fibro-osseous jaw tumor, cystic kidney lesion, and uterine tumor. Germline mutations of the HRPT2 gene (CDC73) coding for parafibromin are identified in approximately(More)
CYP24A1 gene mutations induce infantile hypercalcemia, with high 1,25(OH)2D contrasting with low PTH levels. The adult phenotype is not well known. Two unrelated adult patients were referred for nephrolithiasis, hypertension, hypercalcemia, hypercalciuria, normal 25-OHD levels, and inappropriate PTH levels (22 to 92pg/mL;N: 15-68) suggesting primary(More)
CONTEXT Multiple Endocrine Neoplasia Type 1 (MEN1) is an autosomal dominant inherited syndrome, related to mutations in the MEN1 gene. Controversial data suggest that the nonsynonymous p.Ala541Thr variant, usually considered as a non-pathogenic polymorphism, may be associated with an increased risk of MEN1-related lesions in carriers. OBJECTIVE The aim of(More)
Alpha- 1-antitrypsin (A1AT) deficiency is a hereditary autosomal codominant genetic disorder resulting in low circulating levels of A1AT and leading to lung and/or liver disease. It remains underdiagnosed and only 5 to 10% of PIZZ patients, the most common form of severe A1AT deficiency, would be actually identified in France. Facilitating early diagnosis(More)
