Several secretory acid proteinases from C. albicans and C. tropicalis as well as membrane extracts from two strains of C. albicans were compared for their renin-like activity and for their ability to activate blood coagulation. The highest renin-like activity as measured fluorometrically, was found in the membrane extract of C. albicans 113, it accounted for approximately a tenth of the activity of pure human renin. Activation of blood coagulation by acid Candida proteinases is due to the trypsinogen kinase effect, it was detected preferentially at the level of factor X (Stuart-Prower). Conversion of factor X at rates sufficiently rapid to be of biological significance was effected by several proteinases tested. The highest activity was found in the membrane extract of C. albicans CBS-2730 and involves a proteinase of the serine type. Both renin-like activity and conversion of factor X are examples of limited proteolysis; they are discussed with respect to strain-specific pathogenicity in opportunistic yeasts.

A multilocus assay was used to genotype up to 27 variable sites in 15 genes in French and Italian, presumed to be healthy populations (n=1480, n=162, respectively). These genes are involved in lipid metabolism (APOE, APOB, APOC3, CETP, LPL, PON), homocysteine metabolism (CBS, MTHFR), blood viscosity (Fibrinogen, FV), platelet aggregation (GpIIIa), leukocyte adhesion (SELE), and renin-angiotensin system (AT1R, ACE, AGT). Allele frequencies for all the markers were compared between the two populations. Five allele frequencies differed between the two European countries: APOB 71Ile (p < 0.001), SELE 98T (p < 0.001), SELE 128Arg (p < or = 0.01), APOE E4 (p < or = 0.01) and MTHFR 677T (p < or = 0.01), suggesting the existence of a north-south gradient in European allele frequencies. The other allele frequencies : APOC3 -482T, -455C, 1100T, 3175G, 3206G; LPL -93G, 9Asn, 291Ser; CETP 405Val; PON 192Arg; ACE Del; AGT 235Thr; AT1R 1166C; CBS 278Thr, GpIIIa P1A2; Fibrinogen -455A, FV 506Gln and SELE 554Phe, were similar between the two populations. They were also similar to those observed in other European countries.

The purpose of this study was to examine the relationship between carotid intima-media thickness (CIMT) inter-individual variability and 16 polymorphisms of 11 genes associated with cardiovascular risk factors (genes among lipid and homocysteine metabolisms, blood viscosity, platelet aggregation, leukocyte adhesion and renin-angiotensin system). CIMT was measured by high resolution B-mode ultrasonography in an healthy population of 77 men and 84 women, aged 35-54 years and selected from a French Cohort: the Stanislas Cohort. The polymorphisms studied were genotyped by a multilocus approach. Statistical analyses were carried out by ANOVA, after adjustment of CIMT for age, body mass index, and smoking, and by multiple regression analyses. No association was found with APOB Thr71Ile, APOC3 -482C/T, -455T/C, GpIIIa P1A, AT1R 1166A/C, AGT Met235Thr, CBS Ile278Thr, SELE 98G/T, and SELE Ser128Arg, polymorphisms neither in men nor in women. Although, in women we did not find any association for APOC3 3206T/G, 3175C/G, 1100C/T, CETP Ile405Val, MTHFR 677C/T and fibrinogen -455G/A polymorphisms; in men these polymorphisms were associated with CIMT variability (p< or =0.01; p< or =0.05). The most interesting finding was that altogether these genes in men were able to explain a considerable part, 20.6%, of CIMT variability. Therefore, our study gives a new opportunity to understand CIMT variability.

Although, in women we found always no association for the APOC3 3206T/G, 3175C/G, 1100C/T, the CETP Ile405Val, the MTHFR 677C/T and the fibrinogen -455G/A polymorphism's, in men these polymorphism's were associated with CIMT variability (0.01 < or = p < or = 0.05). The most interesting finding was that altogether these genes in men were able to explain a considerable part, 20.6%, of CIMT variability.

The clinical phenotypes of patients with Bartter syndrome type III sometimes closely resemble those of Gitelman syndrome. We report a patient with mild, adult-onset symptoms, such as muscular weakness and fatigue, who showed hypokalemic metabolic alkalosis, elevated renin-aldosterone levels with normal blood pressure, hypocalciuria and hypomagnesemia. She was also suffering from chondrocalcinosis. A diuretic test with furosemide and thiazide showed a good response to furosemide, but little response to thiazide. Although the clinical findings and diuretic tests predicted that the patient had Gitelman syndrome, genetic analysis found no mutation in SLC12A3. However, a novel missense mutation, p.L647F in CLCNKB, which is located in the CBS domain at the C-terminus of ClC-Kb, was discovered. Therefore, gene analyses of CLCNKB and SLC12A3 might be necessary to elucidate the precise etiology of the salt-losing tubulopathies regardless of the results of diuretic tests.
