Background: About half of the world's populations are infected with Helicobacter pylori, which may create atherogenic lipid profiles and contribute to atherosclerosis and related cardiovascular disease. Furthermore, it has been connected to hematological symptoms like anemia. Even though the high prevalence of H.pylori and its associated complications, including cardiovascular disease and anemia, in Ethiopia, there is little data regarding the risk factors associated with H.pylori infection, such as hematologic parameters, electrolyte imbalances, and lipid profiles.

Methods: A comparative cross-sectional study design with a consecutive sampling technique was employed at Jimma Medical Center among 108 dyspeptic patients. Five (5) ml of blood samples were collected from each participant, and serum was extracted and analyzed using a COBAS 6000 core for the lipid and electrolyte, and whole blood was used with a SYSMEX XN 550 to determine hematological parameters. Data were entered in to Epi-data version 4.6 and exported to SPSS version 25 for analysis. Simple descriptive statistics and chi-square test were used to present the socio-demographic characteristics of the study subjects. Student t-test was used for data comparison and p-value < 0.05 was considered statistically significant.

Results: H.pylori infected patients had significantly decreased levels of red blood cell count (p = 0.002), hemoglobin (p = 0.012), mean corpuscular hemoglobin concentration (p < 0.001), platelet count (p = 0.001), and sodium level (p = 0.006) when compared to the uninfected group. However, total cholesterol (p = 0.001), and low density lipoprotein (p = 0.021) were increased in H.pylori infected patients when compared to the uninfected group.

Conclusions: This study revealed that H.pylori infection can cause derangements of hematologic parameters, electrolyte imbalances, and alterations of lipid parameters which considered as risk factors for anemia and cardiovascular diseases.
