Abstract
H. pylori infection is considered a major global gastric disorder. Furthermore, the spread of H. pylori infection and its effect on systemic disorders and blood is not fully understood. On the other hand, the high percentage of smokers and their impacts on the health system have become a significant concern. Therefore, the current study aimed to compare the H. pylori infection in smokers and non-smokers and their effects on hematological parameters.190 patients participated and were divided into two groups; 95 were smokers and 95 were non-smokers. The Helicobacter pylori detector instrument showed that the participants were infected. Vein blood was collected to check hematological parameters via a fully automatic hematological analyzer (DIAGON Ltd.-D-Cell 60). The recorded data showed that the highest percentage of infected patients was 26-45 years in both smokers and non-smokers (P≤0.05). Furthermore, depending on the residence, our study revealed that the urban cases were the highest percentage compared to rural cases (P≤0.05). The hematological parameters showed that RBCs, Hb, PCV, MCV, MCH, and MCHC were significantly higher in smokers compared with non-smokers (P≤0.05).
