Detecton of Helicobacter Pylori Infecton
in Biliary System in Egyptan Patents with
Calcular Obstructve Jaundice
Abstract
Background: Bacterial infecton was described as one of the precipitatng factor
in cholesterol gallstone formaton and many studies have confrmed the presence
of Helicobacter species in the hepatobiliary system. The aim of our study was
to detect the presence of Helicobacter species in bile juice by polymerase chain
reacton (PCR) in patents presented with calcular obstructve jaundice.
Methods: Bile samples from 75 patents presented with calcular obstructve
jaundice were obtained during Endoscopic retrograde cholangiopancriatography
(ERCP) and subjected to nested PCR for H. pylori DNA detecton and bacterial
culture. Gastric biopsies were also taken for H. pylori rapid urease and culture.
Results: Helicobacter DNA was detected in 11 out of 75 bile sample by nested PCR,
0 were positve by bile culture, 30 were positve by rapid urease test from gastric
biopsy and 5 were positve by gastric biopsy culture.
Conclusion: H. pylori was found in the biliary system, in patents with calcular
obstructve jaundice suggestng that these bacteria may be of etological
importance in gallstone formaton.

Introducton
Helicobacter pylori (H. pylori), is a gram-negatve microaerophilic
bacterium found usually in the stomach, was frst identfed by
Warren and Marshall [1] in 1982 and soon afer it was linked
with chronic gastrits and gastric ulcers [2]. Although H. pylori is
recognized as a human pathogen associated with gastric lesions,
studies have revealed the presence of Helicobacter species with
some extragastric diseases such as cardiovascular diseases,
lung diseases, hematologic diseases, eye and skin diseases,
hepatobiliary diseases, diabetes mellitus, and neurological
disorders [3].
Gallstone disease is one of the common problems afectng
the digestve tract however, the cause of gallstone formaton
beginning with a change in the compositon of bile, leading to
stones formaton [4]. Diferent studies suggest that bacterial
infecton has an important role in the formaton of brown
pigmented gallstones and that the formaton of pure cholesterol
gall-stones depends mainly on cholesterol saturaton and
solubility [5].
In many studies, the presences of diferent Helicobacter species
were shown in the hepatobiliary system [4,6]. Bile-resistant
hepatc Helicobacter species such as H. bilis, H. pullorum, and
F. rappini were isolated from gall bladder (GB) mucosa and bile
juice of patents with chronic cholecystts and gallstones so these
agents may be the key elements in the development of various
GB-related diseases, especially GB cancer [7].
Diagnosis of H. pylori infecton includes invasive (culture of
Biopsy specimens taken by endoscopy) and non-invasive
(serologic testng of the patent's serum antbody response to
the organism) methods [8,9]. Recently Polymerase chain reacton
(PCR) has been a reliable and highly sensitve tool for detecton of
H. pylori gene sequences in clinical specimens [10,11].
