Helicobacter pylori (H. pylori) infection is the main cause of peptic ulcer disease (PUD), mucosa associated lymphoid tissue lymphoma, and gastric cancer (Vilaichone and Mahachai, 2001; Vilaichone et al., 2006). Furthermore, H. pylori eradication potentially reduces the incidence of gastric cancer, especially in high prevalence area of this particular cancer (Ford et al., 2014; Demirel et al., ...

background: regulatory t cells (tregs) and myeloid-derived suppressor cells (mdscs) are two main regulatory cells modulating the immune responses in inflammation and cancer. objective: to investigate and compare tregs and mdscs in peptic ulcer and gastric cancer. methods: patients with dyspepsia were selected and divided into three groups of non-ulcer dyspepsia (nud, n=22), peptic ulcer disease...

background : data concerning the information on the prevalence and association of the helicobacter pylori cytotoxinassociated gene a (caga) with disease is still controversial. the aim of this study was to isolate and identify h. pylori by culture methode from biopsy specimens and its relationship with associated diseases by molecular techniques (pcr). materials and methods: gastric biopsy spec...

background: although helicobacter pylori and non-steroidal anti-inflammatory drugs (nsaids) are the main causes of peptic ulcers disease (pud), recently the prevalence of idiopathic peptic ulcer (ipu) is increasing in most parts of the world. the aim of this study was to assess the prevalence of ipu in kerman, the center of largest province in south-east iran. methods : we included 215 patients...

BACKGROUND Many individuals consulting their GP with upper abdominal symptoms are initially classified as having dyspepsia. Few studies have described the incidence of dyspepsia or the comorbidities, risk factors or prognosis associated with this diagnosis. METHODS We used the UK General Practice Research Database to find patients with a new diagnosis of dyspepsia in 1996 (n = 6,913) and a co...

The recent publication of “Helicobacter pylori infection rate in chronic kidney disease and end-stage renal disease patients with peptic ulcer disease” is very interesting. Chang and Hu noted that “the H. pylori infection rate is lower in PUD patients with CKD and ESRD than in those without CKD.” There are many concerns regarding this report. First, the prevalence of peptic ulcer disease (PUD) ...

DAB (Digital Audio Broadcasting) is the European successor of FM radio. Besides audio services, other services such as traffic information can be provided. An important parameter for data services is the probability of non-recognized or undetected errors in the system. To derive this probability, we propose a bound for the undetected error probability in CRC codes. In addition, results from mea...

Allelic variation among Helicobacter pylori vacA occurs in the signal and middle region of the gene. The aim of the study was to investigate alleleic variation of vacA among H. pylori strains from three regional areas of China and the relationship between vacA alleles and PUD. DNA extracted from 88 clinical isolates of H. pylori was analyzed by type-specific PCR and reverse hybridization line p...

AIM The purpose of this study was to determine quality of life in peptic ulcer patients referring to Al-Zahra hospital of Isfahan. BACKGROUND Peptic ulcer disease (PUD) is one of the most prevalent diseases. Its prevalence is 6-15% and about 10% of people experience its symptom in their life. PUD can have a considerable impact on patients' quality of life (QOL). PATIENTS AND METHODS This de...

conclusions the most predominant vaca genotypes in our areas were s1/m2 and s1/m1, which regard as the genotypes with more virulence intensity. the h. pylori vacas1a, caga genotypes have a significant relationship with the presence of pud and gc in iranian patients with dyspepsia. results in this study, vaca genotypes s1/m2, s1/m1, s2/m2 and s2/m1 were determined in 43.4%, 19.3%, 13.2% and 6% o...
