    Genetic factors have been implicated in the pathogenesis of osteoporosis, a common disorder in primary biliary cirrhosis (PBC). Estrogen receptor-alpha gene (ER-ïżœ), vitamin-D-receptor gene (VDR) and IL-1-receptor-antagonist gene (IL-1RN) are all attractive candidates for osteoporosis susceptibility. Furthermore insulin-like growth factor-I (IGF-I) gene microsatellite repeat polymorphism was found to be associated with osteoporosis in some studies and collagen-Iïżœ1 (COLIA1) Sp1 s allele was associated with lower bone mineral density (BMD) in one study in PBC. IGF-I treatment restored osteopenia and reduced fibrogenesis in experimental cirrhosis. In this study we summarize our results on polymorphisms of the above genes and bone disease in Hungarian PBC patients. Patients and methods: 70 female patients with PBC were enrolled (age:57.6yrs, range:37-76yrs, each AMA-M2 positive, stage II-IV). 139 age-matched female subjects served as controls (age: 55.9 yrs, range:43-72 yrs). COLIA1 Sp1 and IGF-I microsatellite polymorphisms were determined by PCR in all patients and controls. VDR BsmI, IL-1RN variable-number tandem repeat (VNTR) and ER-ïżœ PvuII and XbaI polymorphisms were detected in 33 patients and controls. BMD was measured by dual energy x-ray absorptiometry (Lunar,Prodigy,USA) in lumbar spine (LS) and femoral neck (FN). Results: There was no difference in IGF-I microsatellite repeat polymorphism (192/192=34.2%, 194/192=28.6%, other=37.2%) and COLIA1 Sp1 polymorphism (SS=72.9%, Ss=22.8% and ss=4.3%) and IL-1 VNTR polymorphism between PBC patients and controls, however, the COLIA1 Sp1 s allele was significantly less frequent in patients with PBC (p=0.038). The genotype frequency of VDR BsmI (BB=57.5%, Bb=33.3%, bb=9.1%, p=0.01) and ER-a PvuII (PP=18.2%, Pp=75.6%, pp=6.2%, p=0.03) and XbaI (XX=9.1%, Xx=90.9%, xx=0%, p=0.0003) of the patients was different from that of the control group, with higher frequency of the BB, Pp and Xx genotypes in PBC. Osteoporosis (t score<-2.5) was detected in 22 patients (31.4%). Osteoporotic patients were elder and had longer disease history (p=0.01 for both). An association was found between the IGF-I genotypes and ODM data, the 192/192 genotype was associated with higher FN Z-score compared to other genotypes (p=0.036). Conclusions: In contrast to previous studies the COLIA1 Sp1 s allele was less frequent in patients with PBC, and its presence was not associated with BMD. We confirmed previous findings on higher frequency of VDR BsmI BB genotype in patients with PBC. The ER-α PvuII and XbaI Pp and Xx genotypes were more frequent in PBC patients, while IL-1RN VNTR and IGF-I microsatellite repeat polymorphism was not different. Since IGF-I polymorphism was associated to BMD, it may be hypothesized that not COLIA1 but IGF-I together with other genetic and environmental factors may be involved in the complex regulation of BMD in PBC

Aim: The aim of the authors was to obtain data on the significance of the culprit vessel in patients with ST elevation myocardial infarction treated successfully by primary percutaneous coronary intervention. Method: The authors performed a retrospective study in 10,763 patients with ST elevation myocardial infarction who underwent successful primary percutaneous coronary intervention. The culprit vessels were the left main artery, left anterior descendent artery, left circumflex artery, and right coronary artery. The authors constructed univariate survival curves for different culprit vessels and also performed multivariate modelling of time-to-death, controlling for age, sex, and comorbidities. Results: The majority of the culprit lesions were found in the left anterior descendent artery (44.3%), the right coronary artery (40.9%), and the left circumflex artery (13.7%). The culprit vessel was overall a highly significant (p<0.0001) factor of survival, with right coronary artery exhibiting a highly significantly better prognosis (hazard ratio 0.69, 95% CI 0.61–0.79, p<0.0001) and left main artery exhibiting a significantly worse prognosis (hazard ratio 1.56, 95% CI 1.04–2.35, p = 0.0321) than the reference vessel (left anterior descendent artery). Conclusion: These data demonstrate that the culprit vessel has independent prognostic significance. Orv. Hetil., 2016, 157(32), 1282–1288

    AIM: To determine common NOD2/CARD15 mutations and TLR4 D299G polymorphism in Hungarian patients with CD. METHODS: A total of 527 unrelated patients with CD (male/female: 265/262, age: 37.1 (SD 7.6) years) and 200 healthy subjects were included. DNA was screened for possible NOD2/CARD15 mutations by denaturing high-performance liquid chromatography (confirmed by direct sequencing). TLR4 D299G was tested by PCR-RFLP. RESULTS: NOD2/CARD15 mutations were found in 185 patients (35.1%) and in 33 controls (16.5%, P< 0.0001). SNP8/R702W (10.8% vs 6%, P = 0.02), SNP13/3020insC (19.4% vs 5%, P< 0.0001) and exon4 R703C (2.1% vs 0%, P = 0.02) mutations were more frequent in CD, while the frequency of SNP12/G908R was not increased. The frequency of TLR4 D299G was not different (CD: 9.9% vs controls: 12.0%). Variant NOD2/CARD15 allele was associated with an increased risk for CD (OR(het) = 1.71, 95% CI = 1.12-2.6, P = 0.0001, OR(two-risk alleles) = 25.2, 95% CI = 4.37-, P< 0.0001), early disease onset (carrier: 26.4 years vs non-carrier: 29.8 years, P = 0.0006), ileal disease (81.9% vs 69.5%, OR = 1.99, 95% CI = 1.29-3.08, P = 0.02, presence of NOD2/CARD15 and TLR4: 86.7% vs 64.8%), stricturing behavior (OR = 1.69, 95% CI = 1.13-2.55, P = 0.026) and increased need for resection (OR= 1.71, 95% CI: 1.13-2.62, P = 0.01), but not with duration, extraintestinal manifestations, familial disease or smoking. TLR4 exhibited a modifier effect: age of onset in wt/TLR4 D299G carriers: 27.4 years vs NOD2mut/TLR D299G: 23 years (P = 0.06), in NOD2mut/wt: 26.7 years. CONCLUSION: These results confirm that variant NOD2/CARD15 (R702W, R703C and 3020insC) alleles are associated with earlier disease onset, ileal disease, stricturing disease behavior in Hungarian CD patients. In contrast, although the frequency of TLR4 D299G polymorphism was not different from controls, NOD2/TLR4 mutation carriers tended to present at earlier age. (C) 2005 The WJG Press and Elsevier Inc.

    Absztrakt A meningococcusok közĂŒl MagyarorszĂĄgon többnyire a B szerocsoportĂș okozza a legtöbb megbetegedĂ©st. Az ellene kifejlesztett egyik oltĂĄs (Bexsero) 2014 nyarĂĄtĂłl MagyarorszĂĄgon is kaphatĂł. A szerzƑk összefoglaljĂĄk a betegsĂ©ggel Ă©s az oltĂĄssal kapcsolatos legfontosabb ismereteket, illetve tĂĄrgyaljĂĄk a vakcinĂĄval kapcsolatos jelenleg mĂ©g nyitott kĂ©rdĂ©seket irodalmi ĂĄttekintĂ©s alapjĂĄn. Az immunolĂłgiai adatokon alapulĂł elƑzetes vĂĄrakozĂĄsok alapjĂĄn a Bexsero vĂ©delmet adhat e ritka, de igen sĂșlyos megbetegedĂ©s ellen. Az oltĂĄs azonban rendkĂ­vĂŒl költsĂ©ges, klinikai hatĂ©konysĂĄga mĂ©g tisztĂĄzatlan, Ă©s szokatlanul gyakran okoz lĂĄzreakciĂłt, fƑleg csecsemƑkorban, amikor a legnagyobb szĂŒksĂ©g lenne rĂĄ. A szerzƑk vĂ©lemĂ©nye szerint a hazai ajĂĄnlĂĄs megfogalmazĂĄsĂĄval cĂ©lszerƱ lenne megvĂĄrni, amĂ­g a mĂĄsutt szerzett tapasztalatok alapjĂĄn jobban meg lehet Ă­tĂ©lni az oltĂĄs hasznĂĄt, kockĂĄzatait, költsĂ©ghatĂ©konysĂĄgĂĄt. LĂ©p- vagy komplementhiĂĄnyos Ă©s egyĂ©b immunszupprimĂĄlt betegeknĂ©l, valamint kiemelkedƑen magas egyĂ©ni kockĂĄzat esetĂ©n a Bexsero alkalmazĂĄsa mĂĄr most is indokolt. Orv.

MĂłdszer: A Nemzeti SzĂ­vinfarktus Regiszterben 2014. 01. 01. Ă©s 2015. 06. 30. között 18 091, heveny szĂ­vinfarktus (AMI) miatt kezelt beteg adatait rögzĂ­tettĂŒk; 8334 betegnĂ©l ST-elevĂĄciĂłval jĂĄrĂł (STEMI), 9757 esetben nem ST-elevĂĄciĂłval jĂĄrĂł infarktus (NSTEMI) volt a klinikai diagnĂłzis. A STEMI-csoportban vizsgĂĄltuk az ST-elevĂĄciĂłs (n = 7937), illetve az ĂșBTSZB-s betegek (n = 397) klinikai jellemzƑit Ă©s prognĂłzisĂĄt. A halĂĄlozĂĄs vizsgĂĄlatĂĄra többvĂĄltozĂłs regressziĂłs modellt (Cox-regressziĂłt) hasznĂĄltunk. EredmĂ©nyek: Az AMI-betegcsoportban 1274 esetben (7%) talĂĄltunk BTSZB-t. STEMI klinikai diagnĂłzisa esetĂ©n az ĂșBTSZB-s alcsoportba tartozĂł betegek (n = 397) idƑsebbek voltak, s nagyobb volt a fĂ©rfiak rĂ©szarĂĄnya Ă©s a tĂĄrsbetegsĂ©gek elƑfordulĂĄsa, mint azoknĂĄl, akiknĂ©l a felvĂ©teli EKG-n ST-elevĂĄciĂł volt. A BTSZB-s csoport halĂĄlozĂĄsa mind a 30 napos (25,4% versus 12,4%), mind az 1 Ă©ves idƑpontban (47,3% versus 19,9%) magasabb volt, mint az ST-elevĂĄciĂłs betegcsoportban. A percutan coronariaintervenciĂł (PCI) mindkĂ©t csoportban lĂ©nyegesen alacsonyabb halĂĄlozĂĄssal jĂĄrt egyĂŒtt. Többfaktoros elemzĂ©s sorĂĄn a BTSZB önĂĄllĂł prognosztikai jelentƑsĂ©gĂ©t igazoltuk: az ST-elevĂĄciĂłhoz viszonyĂ­tott hazĂĄrdhĂĄnyadosa 1,33 (95%-os konfidenciaintervallum: 1,10–1,62), kontrollĂĄlva nemre, Ă©letkorra, PCI megtörtĂ©ntĂ©re, szisztolĂ©s vĂ©rnyomĂĄsra, szĂ­vfrekvenciĂĄra, szĂ©rumkreatinin-eltĂ©rĂ©sre Ă©s öt kĂłrelƑzmĂ©nyi/tĂĄrsbetegsĂ©gi adatra. KövetkeztetĂ©s: Az akut szĂ­vinfarktus miatt kezelt betegek prognĂłzisĂĄt a felvĂ©teli EKG is befolyĂĄsolja: BTSZB esetĂ©n az Ă©letkilĂĄtĂĄsok rosszabbak, mint ST-elevĂĄciĂłnĂĄl. Orv Hetil. 2018; 159(17): 677–681. | Abstract: Introduction and aim: By using the database of the National Registry of Myocardial Infarction, the authors examine the prognosis of patients treated with acute myocardial infarction, in case of whom there was new or presumably new left bundle branch block (nLBBB) on the ECG recorded at hospitalization. Method: We recorded the details of 18 091 patients treated with acute myocardial infarction (AMI) between 1 January 2014 and 30 June 2015 in the National Registry of Myocardial Infarction. In case of 8334 patients, the clinical diagnosis was ST-elevation myocardial infarction (STEMI), whereas in 9757 cases it was non-ST elevation myocardial infarction (NSTEMI). In the STEMI population we examined the clinical characteristics and prognosis of patients with ST-elevation (n = 7937) and nLBBB (n = 397). We used the proportional hazards regression model (Cox-regression) to examine mortality. Results: In the AMI patient population, we found LBBB in 1274 cases (7%). In case of STEMI clinical diagnosis, the patients belonging to the nLBBB subpopulation (n = 397) were older, and the proportion of men and the occurrence of co-morbidities was higher than in case of those who had ST-elevation on their ECG recorded at hospitalization. The mortality rate of the LBBB population was higher than that of the ST-elevation patient population in both the 30-day (25.4% versus 12.4%) and the 1-year period (47.3 versus 19.9%). Percutaneous coronary intervention (PCI) had significantly lower mortality in both populations. In the course of a multifactorial analysis we verified the independent prognostic significance of LBBB: the hazard ratio compared to ST-elevation was 1.33 (95% confidence interval: 1.10–1.62), checked for gender, age, occurrence of PCI, systolic blood pressure, cardiac frequency, serum creatinine difference, and the details of five anamneses/co-morbidities. Conclusion: The admission ECG has prognostic significance. Patients with LBBB have poorer prognosis compared to patients with ST-elevation on admission ECG. Orv Hetil. 2018; 159(17): 677–681
