Abstract

Q fever is a disease of high zoonotic potential, but interest in its causative agent is rather low although it causes some public health problems in Hungary. The prevalence of Q fever is highly variable by country. The main reservoirs of the disease are the same domestic ruminant species everywhere, but the epidemiological profile depends on the features of the specific reservoir. The aim of this large-scale study was to demonstrate the importance of Q fever in different species as a possible source for human infection in most regions of Hungary. A total of 851 serum samples from 44 dairy farms, 16 sheep flocks, 4 goat farms and 3 zoos located in different parts of Hungary were tested. The presence of antibodies to Coxiella burnetii was surveyed in dairy cattle (n = 547), goats (n = 71), sheep (n = 200) and zoo animals (n = 33). The animal species tested in Hungary showed different seroprevalence values of C. burnetii infection. Seropositivity by the enzyme-linked immunosorbent assay was found in 258 out of 547 (47.2%) cows and in 69 out of 271 (25.5%) small ruminants, among them in 47 out of 200 (23.5%) sheep and in 22 out of 71 (31.0%) goats. Antibodies to C. burnetii were not detected in zoo animals. Seropositivity was demonstrated in 44 out of 44 (100%) dairy cattle farms, with at least one serum sample found to be positive on each farm. The seropositivity rate of small ruminant farms was 55.0% (11 positive out of 20 tested), with 9 out of 16 (56.3%) sheep flocks and 2 out of 4 (50.0%) goat herds showing seropositivity.

Abstract

Q fever is one of the commonest infectious diseases worldwide. A Coxiella burnetii prevalence of 97.6% has been found by ELISA and PCR tests of the bulk tank milk in dairy cattle farms of Hungary. The herd- and individual-level seroprevalence rates of C. burnetii in the examined dairy cows and farms have dramatically increased over the past ten years. Three high-producing industrial dairy farms were studied which had previously been found ELISA and PCR positive for C. burnetii by bulk tank milk testing. Coxiella burnetii was detected in 52% of the 321 cows tested by ELISA. Pregnancy loss was detected in 18% of the cows between days 29–35 and days 60–70 of gestation. The study found a higher seropositivity rate (80.5%) in the cows that had lost their pregnancy and a seropositivity of 94.4% in the first-bred cows that had lost their pregnancy at an early stage. The ELISA-positive pregnant and aborted cows were further investigated by the complement fixation test (CFT). In dairy herds an average of 66.6% individual seropositivity was detected by the CFT (Phase II) in previously ELISA-positive animals that had lost their pregnancy and 64.5% in the pregnant animals. A higher (Phase I) seropositivity rate (50.0%) was found in the cows with pregnancy loss than in the pregnant animals (38.5%). The high prevalence of C. burnetii in dairy farms is a major risk factor related to pregnancy loss.

Bevezetés: Bélendometriosisról beszélünk abban az esetben, ha az endometriumhoz hasonló szövet infiltrálja a bélsubserosát, illetve eléri a subserosus neurovascularis plexust. A colorectalis endometriosis miatt végzett műtétek hatása az infertilitásra és a terhesség kiviselésére nem minden kétséget kizáróan igazolt. Célkitűzés: A Klinikánkon bélendometriosis miatt végzett idegkímélő anterior reszekción átesett betegek fertilitási adatait vizsgáltuk egy prospektíven létrehozott adatbázis segítségével. Módszer: 2009 és 2017 között 121, bélendometriosis miatt megoperált beteg teherbe esési szándékát, a teherbe esés módját, annak sikerességét, a terhességi kórképek előfordulását és a szülésvezetés módját vizsgáltuk. Statisztikai analízis: Az endometriosis és a terhességi kórképek előfordulása közti összefüggést χ2-próbával és Fisher-egzakt teszttel vizsgáltuk, és meghatároztuk az esélyhányadost (OR) és 95%-os konfidenciaintervallumát (CI). Az eredményt p<0,05 esetén tekintettük szignifikánsnak. Eredmények: Klinikánkon 121, bélendometriosis miatt megoperált beteg közül 48-an (39,6%) estek teherbe, 37-en (30,5%) mesterséges megtermékenyítés segítségével. A kontrollcsoportot andrológiai ok miatt in vitro fertilisatiós eljáráson átesett betegek alkották. Eredményeink azt mutatják, hogy az endometriosisban szenvedő nők körében szignifikánsan gyakrabban alakul ki a terhesség során praeeclampsia (p = 0,023) és placenta praevia (p = 0,045). Következtetések: Vizsgálatunk unikális a bélendometriosis miatt megoperált betegek terhességének és szülésvezetésének vizsgálata kapcsán, ahol a kevés esetszám ellenére hasonló eredményeket kaptunk, mint az eddigi multicentrikus tanulmányok.
