Background: Helicobacter pylori (H. pylori) infection is a global public health problem, a higher burden of the infection was reported in developing countries including Ethiopia. It has been associated with several gastrointestinal diseases, and recently implicated in some hematological abnormalities. Despite the high prevalence of H. pylori infection in Ethiopia, there was limited data regarding the relationship between hematological parameters with H. pylori infection. Therefore, this study aimed to evaluate selected hematological parameters of H. pylori-infected patients attending Wachemo University Nigist Eleni Mohammed Memorial Referral Hospital (WUNEMMRH), Hosanna, Southern, Ethiopia.
Methods and Materials: A comparative cross-sectional study was conducted from January to May 2019 among 374 (187 H. pylori-infected patients and 187controls) study participants. Data on socio-demographic characteristics were collected using a structured questionnaire. A five-milliliter venous blood sample was collected for hematological parameter analysis. Approximately two gram of stool specimen was collected to assess the presence of H. pylori antigen. Data were entered and analyzed by using SPSS version 21. Pearson correlation analysis and independent sample T-test was performed, and P-value < 0.05 was considered statistically significant.
Results: Mean value of Hgb (p< 0.001), RBC count (p< 0.001), HCT (p< 0.001), MCV (p=0.003), MCH (p=0.008), and MCHC (p=0.006) of H. pylori-infected patients were significantly lower than control group. However, the mean value of RDW (p=0.003) in H. pylori-infected patients was significantly higher than in the control group. About 13.3%, 7%, 6.4%, and 18.2% of H. pylori-infected patients showed reduced Hgb concentration, RBC count, HCT, and MCV values, respectively.
Conclusion: The study showed a statistically significant difference in the mean value of Hgb, RBC count, HCT, MCV, MCH, MCHC, and RDW of H. pylori-infected patients and controls. Thus, hematological parameters should be considered for proper diagnosis and management of H. pylori-infected patients and eradication of this microorganism from infected patients, determination of hematological parameters for H. pylori-infected patients were recommended.
