Abstract

Introduction: : Gram-negative bacteria such as Helicobacter pylori (HP) are becomingincreasingly implicated in the etiology of Parkinson’s disease (PD). This study aimed toinvestigate the association between PD and HP infections.Materials and Method: Eighty-three patients with PD and age- and sex-matched healthycontrol subjects with no history of PD were enrolled. Patients with secondary Parkinsonism andsevere cognitive impairment were excluded. All patients were staged according to the Hoehnand Yahr scale. We obtained 10 mL venous blood samples from all patients and controls. Theplasma was separated, and samples were stored at −200°C. IgG antibodies developing againstHP were investigated using the ELISA method. Values >5 IU/ml were considered positive.Results: Eighty-three patients and 81 controls were included in the study. HP IgG waspositive in 87% of the patient group and in 74% of the control group. The median antibodytiter in the patient group was higher than that in the control group (p=0.0019). No significantrelation was observed between disease severity and IgG positivity (p=0.947). However, amoderate correlation was observed between disease severity and mean IgG level (r=0.277,p=0.011). HP IgG positivity (OR 3.15, 95% CI 1.23–8.07, p=0.002), a family history of PD (OR 2.57,95% CI 1.02–4.13, p= 0.03), and male gender (OR 2.05, 95% CI 0.95–6.99, p= 0.02) increase thelikelihood of PD.Conclusion: HP infections may trigger various abnormal or enhanced immunologicalprocesses in patients diagnosed with PD; these abnormal immunological activities areprobably involved in the disease pathogenesis.

Özet

Giriş: Helicobacter pylori (HP) gibi Gram-negatif bakteriler Parkinson Hastalığı’nda (PH) etiyolojik etmen olabilir. Bu çalışmada PH ve HP enfeksiyonu arasındaki ilişki araştırıldı. Gereç ve Yöntem: Parkinson Hastalığı tanısı olan 83 hasta ve yaş-cinsiyet uyumlu olan sağlıklı kontrol grubu çalışmaya alındı. Sekonder parkinsonizm tanısı olan ve ağır bilişsel etkilenmesi olan hastalar çalışma dışı bırakıldı. Tüm hastalar Hoehn Yahr skalasına göre klinik olarak evrelendirildi. Çalışma grubundan 10 ml venöz kan örnekleri toplandı ve plasma ve serumları ayrılarak, örnekler -200°C’de muhafaza adildi. HP’ye karşı oluşan IgG’ler ELİSA yöntemiyle bakıldı ve değerin >5 IU/ml’in üzerinde olması pozitif olarak değerlendirildi. Bulgular: Çalışmaya 83 hasta grubu ve 81 sağlıklı kontrol grubu dahil edildi. Parkinson hastalığı olan grupta %87, kontrol grubunda %74 oranında HP IgG pozitifliği saptandı. Hasta grubunun ortalama antikor titresi kontrol grubuna göre anlamlı olarak daha yüksekti (p=0.0019). Hastalık şiddeti ve IG pozitifliği arasında korelasyon saptanmadı (p=0.947). Ancak, hastalık şiddeti ile ortalama IgG düzeyleri arasında orta derecede korelasyon saptandı r=0,277, p=0.011). HP IgG pozitifliğinin (OR 3.15, 95% CI 1.23–8.07, p=0.002), ailede PH öyküsü olmasının (OR 2.57, 95% CI 1.02–4.13, p= 0.03) ve erkek cinsiyetin (OR 2.05, 95% CI 0.95–6.99, p= 0.02 ), PH olma olasılığını anlamlı biçimde artırmış olduğu saptandı. Sonuç: : HP enfeksiyonu, çeşitli immünolojik yolaklar üzerinden PH ‘yı tetikleyebilir ve bu anormal immün reaksiyonlar hastalık patogenezinde olasılıkla rol oynamaktadır.
