ЗАСТОСУВАННЯ ПОЛіМЕРАЗНО ЛАНЦЮГОВОЇ РЕАКЦІЇ З МЕТОЮ ВИЯВЛЕННЯ ХЕЛІКОБАКТЕРНОЇ ІНФЕКЦІЇ ПРИ ЗАХВОРЮВАННЯХ ЖОВЧОВИВІДНИХ ШЛЯХІВ

ЗАСТОСУВАННЯ ПОЛіМЕРАЗНО ЛАНЦЮГОВОЇ РЕАКЦІЇ З МЕТОЮ ВИЯВЛЕННЯ ХЕЛІКОБАКТЕРНОЇ ІНФЕКЦІЇ ПРИ ЗАХВОРЮВАННЯХ ЖОВЧОВИВІДНИХ ШЛЯХІВ

Abstract

Helicobacter. Обобщая проанализированы литературные данные, можно утверждать, что определенную роль в формировании желчных камней играют отдельные виды бактерий рода Helicobacter.The paper give grounds application of polymerase chain reaction to detect bacteria of the genus Helicobacter in biliary diseases. It has proved to be a highly specific method indicating the presence of DNA specific section of pathogens in the test material. The infection detection is possible even if the material taken from a patient contains only one cell of bacteria or virus. The uniqueness of the abovementioned diagnosis method is also evident with its high speed results. The high sensitivity of PCR to diagnose infection not only in the acute stage of the disease, but in chronic infection with the presence of a single bacteria or viruses as well. Under conducting the analysis of the tested material a specific DNA fragment is released, that is peculiar only to a particular pathogen, i. e. only to a certain bacteria or virus. This section of DNA is unique and is not typical for any infection. In our country, this diagnostic method has become widespread lately but it is not widely used for the diagnosis of H. pylori. There has studied 84 samples of bile and gallbladder wall obtained intraoperationally in patients with diseases of the biliary tract. The positive were considered samples in which two on the level of internal control and the positive control. Negative were considered samples in which only one amplification product lines was determined on the level of internal control. Among the subjects there were 28 patients 33. 3% males; 56 patients 66. 7% females. In 35 patients 42 % obtained positive result in bile and gallbladder wall under PCR reaction, i. e. positive Helicobacter. In 49 patients 58% negative Helicobacter. Considering the high percentage of positive samples of Helicobacter of bile in patients with biliary tract disease it is possible to assume H. pylori infection as the cause of stone forming genesis. Analysis of the published papers on molecular detection of bacteria of Helicobacter DNA genus in the gallbladder in patients with chronic cholecystitis shows that as early as in 2003, Chen W. et al. in bile samples obtained at cholecystoectomy, the DNA bacteria was detected in 50 % of cases, while in 56 of the 61 positive samples the DNA was related to H. pylori. In our study, using identical methods of DNA isolation from samples of gallbladder wall we got the results that indicate the presence of the bacteria genes in 42 % of cases. This emphasizes again that molecular modern biology is an extremely valuable tool for the identification of microorganisms. Polymerase chain reaction can become the “gold” standard for detection of bacteria of the genus Helicobacter. Analysis of the published reports and the results obtained in this study indicates the need for standardization of methods of genetic detection of bacteria of the genus Helicobacter and development of commercial kits available for practical laboratories. Summarizing the analyzed literature data, it can be argued that certain types of bacteria of the genus Helicobacter play their role in the formation of gallstones.

Обґрунтовано перспективність застосування полімеразно-ланцюгової реакції з метою виявлення бактерій роду Helicobacter при захворюваннях жовчовивідних шляхів. Доведено, що це високоспеци-фічний метод оскільки безпосередньо вказує на наявність в досліджуваному матеріалі специфічної ділянки ДНК збудника хвороби. У нашому дослідженні при використанні однакової методики виділення ДНК із зразків жовчі та слизової жовчного міхура отримані результати, що вказують на присутність генів бактерії в 42% випадків. Доведено, що молекулярна біологія нині є надзвичайно цінним інструментом для ідентифікації мікроорганізмів. Полімеразно-ланцюгова реакція може стати «золотим» стандартом детекції бактерій роду Helicobacter. Узагальнюючи проаналізовані літературні дані, можна стверджувати, що певну роль у формуванні жовчних каменів відіграють окремі види бактерій роду Helicobacter.Обосновано перспективность применения полимеразно-цепной реакции с целью выявления бактерий рода Helicobacter при заболеваниях желчевыводящих путей. Доказано, что это высокоспецифичный метод поскольку непосредственно указывает на наличие в исследуемом материале специфического участка ДНК возбудителя болезни. В нашем исследовании при использовании одинаковой методики выделения ДНК из образцов желчи и слизистой желчного пузыря получены результаты, указывающие на присутствие генов бактерии в 42% случаев. Доказано, что молекулярная биология ныне является чрезвычайно ценным инструментом для идентификации микроорганизмов. Полимеразно-цепная реакция может стать «золотым» стандартом детекции бактерий рода
