[Gas analyzer "HelicoSense" as a new device for diagnosis of the Helicobacter infection].

According to recommendations of the European Health Committee, noninvasive methods should be preferred for diagnosis of Helicobacter pylori (HP) infection in children. Equipment and reagents for respiration diagnostic tests available from foreign manufacturers have rather high cost, which hinders their use in domestic medical institutions. A new noninvasive electrochemical technique for HP detection is based on the use of HelicoSense gas analyzer. 150 patients (100 children 6-17 years old and 50 adults 18-78 years old) participated in mulicenter testing of the developed technique. Chronic gastritis was previously diagnosed by endoscopic and morphological examination in all patients. HP status was studied using bacteriological, serological, and cytological methods, as well as the Helpil test. The obtained results were compared to the results of examination with HelicoSense gas analyzer. Our study showed that HelicoSense gas analyzer provides easy use, patient's safety, and possibility of rapid testing. Its application does not require specially trained medical personnel. The device provides high specificity (86.7%) and high sensitivity (93.7%).
