Introduction: The aim of this study was to investigate the relationship between Helicobacter pylori occurrence and, Cytotoxinassociated gene A (CagA) seropositivity with hemodialysis (HD) duration, Serum C-reactive protein (CRP) and hemogram parameters in hemodialysis patients. Materials and Methods: This study included 165 prevalent HD patients. Blood samples were collected before dialysis treatment of the patients. The samples were then centrifuged at 1500 x g for 10 min. immediately after collection. The presence of serum IgG antibody for H. pylori was determined using commercial ELISA kits. Serum anti-CagA IgG antibody of H. pylori positive patients was determined by ELISA method using commercial ELISA kits. CRP levels were measured by nephelometric method, and hemogram parameters were analyzed using fully automated hematology analyzer. Results: We found that the CRP levels of the patients having H. pylori were significantly high. However, there was no significant difference between CRP levels of long-term hemodialysis (LTHD) and short -term hemodialysis (STHD) patients. The possibility of being seropositive of CagA for STHD patients having H. pylori was found to be 2.3 times higher than that of LTHD patients. In addition to that, the periodicity of gastrointestinal (GI) bleeding was significantly high in STHD patients. Conclusion: In conclusion, we found no relationship between dialysis duration and H. pylori prevalence. However, we observed significantly higher odds ratio for CagA seropositivity in patients receiving STHD. These findings suggest that longer dialysis treatment can cause improving effects on H. pylori virulence. Further studies are needed to verify these findings.

CONTEXT: The association between Helicobacter pylori infection and colon neoplasia has been the subject of recent investigations which have produced controversial results. OBJECTIVE: To evaluate the prevalence of H. pylori infection in patients with colonic adenomas and also in patients whose colonoscopy exams were normal. METHODS: After colonoscopy, the individuals were distributed into two groups: patients with colon adenomas (cases) and patients whose colons were normal (controls). The groups were similar regarding age and gender. The individuals of both groups were subjected to a dosage of IgG antibody against H. pylori. The dosage was applied according to the solid phase, chemiluminescent immunometric assay. The chi-square test was used to analyze the data. RESULTS: There were 30 men and 64 women in each group (94 cases and 94 controls). The mean age of the cases was 59.79 ± 12.25 years and that of the controls was 58.98 ± 11.55 years. The H. pylori serology was positive for 66 (70.21%) of the cases and for 51 (54.25%) of the controls. There was a significant difference (P = 0.024). The odds ratio was 1.98 (CI 95%, 0.82-3.15). The prevalence of H. pylori in cases and controls according to gender, histological type and location of the colon lesions showed a significant difference only among women (P = 0.03), among patients with tubular adenomas (P = 0.03), and in those with distal adenomas (P = 0.038). CONCLUSION: There is a positive association between H. pylori infection and colonic adenomas. This association is more evident in women, especially for tubular adenomas and distal colonic location.

Background. Some studies suggest a significant relationship between Helicobacter pylori infection and atherogenesis; but the mechanism of the relationship is almost unknown. The current study aimed at evaluating the relationship between H. pylori infection and serum lipid profile. Patients and Methods. The current study was conducted on 2573 patients, from 2008 to 2015. The serum anti-Helicobacter pylori antibody titer and serum lipid profile were assessed in the study population; data were statistically analyzed by SPSS version 16. P values < 0.05 were considered significant. Results. In the current study, 66.5% of the cases were serologically positive for H. pylori. Among male cases, the level of low density lipoprotein (LDL) was higher in patients with H. pylori infection, compared with that of the ones without the infection (P=0.03); although level of triglyceride (TG) was higher and the level of high density lipoprotein (HDL) was lower in the cases with H. pylori infection; there was no statistically significant difference between the cases with and without H. pylori infection regarding the level of HDL and TG. Among female cases, the level of TG was significantly lower in patients with H. pylori infection, compared with that of the ones without the infection (P=0.001); but there was no significant difference between the cases with and without H. pylori infection regarding the level of LDL and HDL. The mean fasting blood sugar (FBS) in the cases with H. pylori infection was significantly higher than that of the ones without the infection (P=0.04). Conclusion. According to the results of the current study, the levels of LDL and FBS were high among the male cases with H. pylori infection. However, in females with H. pylori infection the level of TG was low; hence, it seems that the atherogenicity of H. pylori affected the level of blood sugar more.

4091 Background: The relationship between Helicobacter pylori (H.pylori) and hepatocellular carcinoma (HCC) was first proposed in 1994. Since then, several studies have been performed to explore the association. The role of Hepatitis C (HCV) viruses coexisting with H.pylori in causing HCC was also studied. With the emergence of data in this regard, a causal relationship has been postulated, but not confirmed, and hence the relationship remains controversial. Our meta-analysis aims to summarize the research on this topic and investigate if there exists a relationship between H. pylori infection and the development of HCC and if the presence of HCV along with H.pylori plays a role in liver carcinogenesis. Methods: Following PRISMA guidelines, we performed a systematic review of all relevant studies published in the literature using keywords “Helicobacter pylori” and “Hepatocellular carcinoma” on major literature databases, including PubMed, EMBASE, Web of Science, and Cochrane controlled trials register. A total of 656 studies were identified between 1994 to March 2020, out of which 26 studies qualified under our selection criteria. Patients positive for HCC are included as cases and patients that did not have HCC under control group. In both groups, H.pylori positive patients and their HCV status, was identified. Results: Out of the 26 studies included in the final analysis, the prevalence of H. pylori infection was 64.78% (561 of 866) amongst HCC cases and 47.92% (1718 of 3585) in the non-HCC control group. The summary odds ratio for the association of H. pylori infection with the risk for HCC using the random-effects model was determined to be 4.75 (95% CI, 3.06-7.37), I²=63%. Subgroup analysis to determine the odds of developing HCC in the presence of H.pylori and HCV coinfection, was 13.97 (95% CI, 3.94-49.61), I²=81%. Whereas, the odds of developing HCC in the presence of only HCV without H.pylori was found to be 2.21 (0.70-6.94), I²=79. Subgroup analysis by study design showed no significant difference between the study groups (P= 0.5705). Conclusions: Our meta-analysis showed a positive association between H. pylori infection and the development of HCC. It showed a significantly higher risk of developing HCC in the presence of HCV infection along with H.pylori. Further prospective cohort studies are needed to prove the causal relationship, especially in cases of Hepatitis B, C coinfection, and cirrhotic patients.[Table: see text]

The objective was to investigate the prevalence and the association between blood groups and <em>Helicobacter pylori</em> IgG seropositivity among pregnant Sudanese women. A cross-sectional survey was carried- out at Saad Abul Ela Maternity Hospital, Khartoum, Sudan during the period of July 2014 through December 2015. Questionnaires covering socio-demographic and obstetrics information were administered. Specific <em>H. pylori</em> IgG antibody was analysed using ELISA. One hundred eighty six pregnant women were enrolled. The mean (SD) of the age, parity was 28.3 (2.6) years and 2.6 (3.5), respectively. Of the 186 women, 42 (22.6%), 24 (12.9%), 11(5.9%) and 109 (58.6%) had blood group A, B, AB and O, respectively. <em>H. pylori</em> IgG seropositivity rate was 132/186 (71.0%). There was no significant difference in age and parity between women with <em>H. pylori</em> IgG seropositive and seronegative. Compared with the women with <em>H. pylori</em> IgG seronegative, significantly higher numbers of women with <em>H. pylori</em> IgG seropositive had O blood group, [84/132(63.6) <em>versus</em> 25/54(46.3), P&lt;0.001]. In binary logistic regression, women with O blood group (OR= 2.084, 95% CI=1.060 -4.097, P=0.033) were at a higher <em>H. pylori</em> IgG seropositivity. The current study showed that women with blood group O were at higher risk for <em>H. pylori</em> IgG seropositivity.

Introduction: Numerous studies have reported a high prevalence of Helicobacter pylori infection among healthy and non-healthy persons in different places. The Aim of the study is to investigate the seroprevalence of H. pylori infection among Kosovo’s Blood donor associated with ABO/Rhesus blood group.Methods: 671 blood donors are tested for H. pylori antibodies and results are classifi ed by way of donation, age, gender, blood groups and education level. Serum antibodies are analyzed by Enzyme Linked Fluorescent Assay test for H. pylori IgG with Biomerieux HPY-VIDAS.Results: The frequency of IgG antibody for H. pylori among healthy blood donors is 56.9%, there is not found any difference between voluntary and non-voluntary blood donors (57.4% respectively 56.3%)(OR=1.05; 95% CI 0.76 to 1.43; p=0.8). H pylori IgG antibodies positive are detected in 57.0 % ( 126 of 221) of women, compared with 56.9 % ( 256 of 450) of men(OR=0.99; 95% CI 0.72 to 1.38; p=0.96). Serpositive donors are older than seronegative ones (31.9 years, respectively 29.5 years, p=0.02). Mean value of IgG antibody of H. pylori is 3.61 with no significant difference between males and females (3.72 respectively 3.44; p=0.2). The seroprevalence of H. pylori infection is similar among blood groups: O (57.4%), A (56.2%), B (59.6%), AB (51.4%), RhD positive (56.7%) and RhD negative (58.3%).Conclusions: The seropositivity of H. pylori is moderately higher in the non voluntary and familiar blood donors among the total Kosovo blood donors. There is not found a significant relationship between infection with H. pylori and ABO/Rhesus blood group among blood donors.

Abstract Aim Helicobacter pylori (H. pylori) is one of the most common, well-known pathogenic agents in the development of peptic ulcers. Some investigators have shown a relationship between H. pylori and recurrent aphthous stomatitis (RAS). However, this relationship is controversial. The aim of this study was to determine the association between H. pylori and RAS using the urea breath test (UBT). Methods and Materials Forty-three patients with RAS and 44 non-RAS controls were evaluated. There were no differences in gender or age in the two groups. The UBT was used to detect H. pylori infection. Data were analyzed using the Chi Square Test. Results Sixteen individuals in the RAS patients (37.2%) and 14 individuals in the control group (31.8%) had a positive breath test. The difference was not considered statistically significant (p=0.597). Conclusion In the present study no statistically significant difference was found between frequency of a positive UBT in the RAS patients and the control group. Clinical Significance Since the probability of a positive test was higher in the more severe cases this factor needs to be considered in the diagnosis and treatment of RAS.

ABSTRACT We analyzed the specific anti-Helicobacter pylori immunoglobulin G (IgG) antibody profile for a sample of 824 asymptomatic schoolchildren in southern Germany (mean age, 10.7 ± 0.65 years) with an H. pylori-specific IgG enzyme-linked immunosorbent assay and Western blot analysis. The prevalence of infection was 19.8% (95% confidence interval, 17.1 to 22.7%). The immunoresponses were characterized predominantly by antibodies against low-molecular-mass antigens of 14 and 29 kDa, with a significant difference between children of German and Turkish nationalities (P = 0.0012 and P < 0.0001, respectively).

Objective Helicobacter pylori commonly occurs in the stomach, but localizations outside the stomach and related diseases have also been investigated. However, the relationship between H. pylori and gallstones remains controversial. We aimed to investigate the relationships between H. pylori in the stomach and the gallbladder and gallstones. Methods This prospective case-control study included patients who underwent cholecystectomy because of gallstones, pancreatic head cancer, or hepatic resection. The patients were separated into two groups according to the detection of H. pylori in gallbladder samples using Giemsa staining. Stomach H. pylori status was based on previous gastroscopy. Results The study enrolled 60 patients, comprising 27 patients with gallstones and 33 without. There was no significant difference in the incidence of gallstones between patients with or without H. pylori in the stomach or gallbladder. Furthermore, the presence of H. pylori in the stomach was measured in 14 patients and was significantly correlated with H. pylori in the gallbladder. Conclusion The current study showed no relationship between the occurrence of gallstones and the presence of H. pylori in either the gallbladder or the stomach. In contrast to previous reports, this suggests that H. pylori does not play a role in the development of gallstones.

Recent studies have shown a correlation between Helicobacter pylori (H. Pylori) infection and the neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR). The aim of this study was to investigate the relationship between H. Pylori infection and hematimetric indices in patients with dyspepsia symptoms. Overall, 448 patients who underwent gastroscopy were analyzed retrospectively. Histopathological evaluation of biopsies according to H. pylori presence was classified as H. Pylori positive and negative groups, which are analyzed in relation with hematimetric indices. NLR and PLR measurements did not show a statistically significant difference between H. pylori negative and positive groups (p > 0.05). NLR revealed a negative correlation between hemoglobin (HGB), iron, and ferritin measurements in the correlation analysis of the H. Pylori positive group (r = −0.133, p = 0.031; r = −0.270, p = 0.002; r = −0.162, p = 0.032). Again, with PLR, there was a negative correlation between HGB, mean corpuscular volume (MCV), iron, and ferritin measurements (r = −0.310, p = 0.001, r = −0.187, p = 0.002, r = −0.335, p = 0.001; r = −0.290; p = 0.001). The results of our study do not reveal an association between H. pylori presence and inflammatory response, which is evaluated by NLR and PLR measurements in patients with dyspepsia. However, low serum iron and ferritin values of H. pylori-positive patients suggest the effect of H. pylori on iron metabolism.
