Obstruktív alvási apnoéban szenvedő betegek jellemzői hazai beteganyagon

Bevezetés és célkitűzés: Az obstruktív alvási apnoe (OSA) a felnőtt lakosság jelentős részét érintő betegség, mely ismert rizikófaktora a cardiovascularis és metabolicus betegségeknek és a korai halálozásnak. Mindazonáltal kevés magyar- országi adat áll rendelkezésre az OSA-ban szenvedő betegek demográfiai és klinikai jellemzőiről, így vizsgálatunk célja ennek bemutatása volt. Módszer: Retrospektív vizsgálatunkban a Semmelweis Egyetem Pulmonológiai Klinikájának Alváslaboratóriumában kivizsgált 394 személy (58 [46–66] év, 73% férfi, testtömegindex [BMI] = 32,5 [29,2–37,5]) adatait elemeztük, akik kitöltötték az Epworth Álmosság Skálát, poliszomnográfiás vizsgálaton estek át; felvettük az anamnézist, és 255 eset- ben reggeli éhomi vérvétel történt. Eredmények: 282 esetben igazolódott OSA. Ebben a csoportban magasabb volt a férfiak aránya (66 vs. 35%), maga- sabb volt az életkor (59 [48–66] vs. 47 [39–60] év) és a BMI (32,11 [27,78–37,18] vs. 25,29 [22,04–29,03] kg/m2), magasabbak voltak a C-reaktív protein értékek (3,0 [1,71–5,34] mg/l vs. 1,71 [0,91–3,31] mg/l), illetve a betegek gyakrabban szenvedtek társbetegségekben a kontrollcsoporthoz képest (magas vérnyomás 74% vs. 39%, cukorbeteg- ség 24% vs. 11%, dyslipidaemia 46% vs. 30%, szív- és érrendszeri betegség 22% vs. 5%, szívritmuszavar 27% vs. 16%; minden p<0,05). Bár az OSA valószínűsége progresszívan nőtt az életkorral és az Epworth Álmosság Skála emelke- désével, a trendekben szignifikáns különbségeket észleltünk a férfiak és a nők között (mindkettő p<0,05). Ezzel szemben az OSA valószínűségének BMI-függése nemektől független volt (p = 0,94). Következtetés: Az OSA valószínűsége progresszívan emelkedik a kor, a BMI és a nappali aluszékonyság függvényében, ugyanakkor ezt befolyásolja a nem is. Közleményünk rámutat a társbetegségek szűrésének fontosságára is az OSA különböző súlyossági fokaiban

A parlagfű okozta légzőszervi allergiás megbetegedések előfordulása Magyarországon

INTRODUCTION: Although the prevalence of ragweed allergy in Europe is still low, it is increasing according to recent statistics. In contrast, in Hungary ragweed is the most common allergen with very high sensitisation in the general Hungarian population. AIM: We investigated the number and clinical characteristics of ragweed allergy in the Hungarian population, as the first comprehensive study to evaluate ragweed allergy in Hungary. METHOD: One thousand Hungarian adult subjects were screened with a questionnaire for ragweed allergy. People with ragweed allergy answered further specific questions about their disease history, symptoms and medication use. RESULTS: 305 subjects reported allergy from which 218 patients had symptoms during ragweed pollination suggesting ragweed allergy. 40% of these had symptoms for more than 5 years. Asthma was reported in 18.3%. Around 24% of these patients were undiagnosed; they did not take any medications or visited professionals because of their symptoms. Compared to the non-ragweed allergic patients, subjects with ragweed allergy were older and better educated, but the dominance of female gender was less prominent than in the non-ragweed group (all p<0.05). CONCLUSIONS: Around 22% of the Hungarian population suffers from ragweed allergy. Studies should focus on eradication strategy and improvement of patient care. Orv. Hetil., 2016, 157(50), 1989-1993

Exhaled breath condensate in chronic obstructive pulmonary disease: Methodological challenges and clinical application

Collection of exhaled breath condensate (EBC) is a non-invasive method to sample the airway lining fluid. The composition of EBC may reflect physiological and pathophysiological processes within the lower airways, which could otherwise be investigated only with more invasive techniques. Hence, analysis of the condensate fluid seems feasible in chronic obstructive pulmonary disease (COPD) to monitor disease processes and facilitate personalized therapy. In the past two decades, a multitude of molecules has been assessed in EBC samples from patients with COPD, characterizing inflammation, oxidative and nitrative stress in this disorder. Recently, multimarker profiling with sensitive metabolomic or proteomic approaches, optimized for the EBC matrix, has also been applied, which could overcome the pitfalls of single marker detection using commercial assay systems. In this review, we describe the theoretical background of EBC formation, systematically discuss technical and methodological difficulties of sample collection and analysis and summarize data on EBC biomarkers in COPD. Finally, based on previous findings and our experience, we propose potential future directions for the EBC research community, which could pave the way for introducing EBC analysis in clinical practice. © 2018 EDIZIONI MINERVA MEDICA

Circulating survivin levels in healthy and asthmatic pregnancy.

BACKGROUND: Asthma is one of the most common conditions which complicate pregnancy. Pro- and anti-apoptotic mechanisms can be modulated by asthma accompanying pregnancy. Survivin, an anti-apoptotic protein has been implicated in the pathomechanism of asthma and also in the development of pathological pregnancies; however survivin has not been studied in pregnant asthmatics. METHODS: Twenty-eight asthmatic pregnant (AP), 25 asthmatic non-pregnant (ANP), 21 healthy pregnant (HP) and 29 healthy non-pregnant (HNP) women were enrolled in this cross-sectional study. Plasma survivin concentration was determined by ELISA. RESULTS: Plasma survivin was significantly lower in HP (1.64 /0-74.9/ pg/ml) than in HNP (24.6 /0-333.3/ pg/ml, p = 0.01). However, this difference was not observed between the asthmatic groups (p = 0.64). Similarly, there was no difference either between HNP and ANP (10.5 /0-215.4/ pg/ml, p = 0.23) or between HP and AP (13.9 /0-364.1/ pg/ml, p = 0.30) groups. CONCLUSIONS: Decreased plasma survivin levels in physiological but not in asthmatic pregnancy may suggest that the normal apoptotic mechanisms are compromised in asthmatic gestation
