Abstract

___________________________________________________________________________________________________________________

Background: H. pylori is a gram-negative, spiral shaped, Microaerophile pathogenic bacterium that specifically colonizes on the gastric epithelium, it is one of the most common human bacterial pathogens and is the main etiological factor for peptic ulcer disease, simple gastritis and gastric malignancy. The immune status of diabetic patients is compromised, which may lead to an increased susceptibility to H. pylori infection. The aim of this study is to assess Association between Helicobacter pylori and Diabetes Mellitus.

Methods and Material: This was a cross-sectional study with 102 diabetic patients (both IDDM and NIDDM). H.pylori was assessed through the determination of stool antigen by Immunochromatography. 

Results: Out of 102 samples were collected from diabetic patients, 58 were male and 44 were female. 52.9% of them are positive for H.pylori and 47.1% are negative. The mean ages of H.pylori positive patients were 44.01 years where the mean age of negative patients were 42.47 years. There was a statistically significance association (p=0.007) between the diabetes and H.Pylori infection, also there was association between history of GIT disorder and H. pylori infection, between smoking and H. pylori infection. 

Conclusion: The study showed that Helicobacter pylori infection was significantly higher in diabetes Mellitus.

INTRODUCTION

H. pylori is a gram-negative, spiral shaped, Microaerophile pathogenic bacterium that specifically colonizes on the gastric epithelium, it is one of the most common human bacterial pathogens and is the main etiological factor for peptic ulcer disease, simple gastritis and gastric malignancy .1  In some cases, such as immunodeficiency and underlying diseases, it can be problematic as opportunistic infections.2 It represents one of the most widespread bacterial infections globally. 2-3

Helicobacter pylori (H. pylori) infection is now broadly accepted that infection with H.pylori is one of the most common chronic infections worldwide; it approximately 50% of the world population is estimated to be infected with H. pylori. Its prevalence has been demonstrated to range considerably according to socioeconomic status and tends to be more serious in developing countries. 4

Elevated antibodies level against H. pylori also attracted the attention to some extra‑gastric diseases, including diabetes mellitus.2

Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. it is one of the fastest growing diseases worldwide, projected to affect 693 million adults by 2045. Devastating macrovascular complications (cardiovascular disease) and microvascular complications (such as diabetic kidney disease, diabetic retinopathy and neuropathy) lead to increased mortality, blindness, kidney failure and an overall decreased quality of life in individuals with diabetes. 5

Gastrointestinal inflammation caused by H. pylori can influence the absorption of glucose and lipids, which are also abnormal in DM patientsIt is a common infection in diabetic patients who have inadequate metabolic control, individuals are colonized by H. pylori infection in the gastric antrum, probably because of chemotactic factors such as tumor necrotic factor (TNF), interleukins-IL-1, IL-2, and IL-8, which are present in gastric epithelium6. Several studies reported that the relationship between H.pylori and diabetes Mellitus remains controversial. With few studies reported in Sudanese diabetic patients, so this study aims to determine the association between helicobacter pylori and diabetes mellitus.

 

 

MATERIALS AND METHODS

This study was cross-sectional study, that was carried out between August 2022 to December 2022.  The research was carried out in  Jabir Abu Eliz diabetic centre, Khartoum state, sudan.  All diabetic patients attending jabir abu eliz diabetic centre at the study period had been included, with 102 stool sample were collected from these patients.

Sample collection and Laboratory investigation

A stool sample was collected using sterile container and was tested by detecting stool antigen using Immuno-chromatography kits.

H.pylori Antigen detection method by ICT

The H.pylori antigen rapid test a double antibody sandwich technique based lateral flow chromatographic immunoassay. Two drops of the sample after diluted with buffer were squeezed into the well of cassette. The result was readed after 5 minutes, a positive result was confirmed by the presence of red line,while the negative result was indicated by the absence of red line.

Data collection and Analysis

Data was collected using structured questionnaire. Age, sex, body mass index, duration of DM. the diabetic patients were also enquired for intake of treatment, family history of diabetes mellitus, state of smoking, history of GIT infection, and chronic disease status. The collected data was proceeded for analysis using SPSS version 23.

RESULTS

A total of 102 samples were collected from diabetic patients, 52.9% of them are positive for H.pylori and 47.1% are negative. The mean age of H.pylori positive patients were 44.01 years where the mean age of negative patients were 42.47 years with a no statistically significance association (p=0.711) between age and H.Pylori. The mean duration of DM for H.pylori positive patients were 7.39 years where the mean duration of DM for negative patients were 6.72 years with a no statistically significance association (p=0.660) between the diabetes and H.Pylori as indicated by (Table 1,2).  Diabetic patients was assessed with regard the H.pylori results, of the 102 participants, all of them (100%) were diabetic with a statistically significance association (p=0.007) between the diabetes and their H.pylori as indicated (Table 3).

DISCUSSION

In the present study, we found a significant association between H. pylori infection and diabetes, while other studies did not find an association between H. pylori infection and diabetes. So the relationship between H. pylori infection and diabetes remained controversial for the last years. However, several studies supported my result on the positive association between H. pylori infection and diabetes 4, 9.  In contrast, others found H. pylori infection to be positively associated with diabetes 7, 10

Regarding the chronic diseases, there was no statistical significant association (p=0.103) between the hypertension and H.Pylori infection and this were consistent to publish studies8. In contrast, others found H. pylori infection to be positively associated with hypertension4. According to the history of GIT, there was statistical significant association (p=0.045) between the history of GITand H.Pylori infection and this was consistent to publish studies11. 

With regard to history of smoking there was statistical significant association (p= 0.004) between the status of smoking for the participants and H.Pylori infection and this was consistent to publish studies11. In which there was significant association (p= <0.001) between smoking for the participants and H.Pylori infection.

According to the BMI of the participants, the majority (61%) of the participants were normal and there was no statistical significant association (p >0.05) between the BMI of the participants and H. pylori infection and this was contradictory to publish studies12 in which there was significant association (p= <0.0001) between the BMI of the participants and H. pylori infection. 

According to the gender of the participants, 56.9% was male and 43.1% was female and there was no statistical significant association (p0.213) between the gender of the participants and H. Pylori infection and this were consistent to publish studies12. 

Regarding the educational level of participants, there was no difference in education between Illiterate, primary, secondary, and university participants about Helicobacter pylori results and also there was no statistical significant association (p=0.322) between the educational level of participants and H. Pylori infection and this was contradictory to publish studies4.

Regarding the type of treatment for participants, there was no statistical significant association (p=0.119) between the type of treatment and H. pylori and this were consistent to publish studies8. Although we know that there is a strong relationship between diabetes and family history, in my study, the majority (66.7%) of the participants had no family history of diabetes and also there was no statistically significant association (p=0.400) between the family history of diabetes and H. pylori infection and this was consistent to publish studies4.  

CONCLUSION

The study concluded that there was association between Helicobacter pylori and Diabetes Mellitus, between history of GIT disorder and H.pylori infection and  between smoking  and H. pylori infection.
