Objective The aim was to investigate the existence of immunoglobulin (Ig)G antibody against Helicobacter pylori (H. pylori) in blood sample from patients having laryngeal lesions and comparing its level in benign versus malignant lesions. Patients and methods Under general anesthesia, direct laryngoscopy was performed for patients having laryngeal lesions, and biopsy was taken and sent for histopathology. Anti-H. pylori IgG antibodies were measured by enzyme-linked immunosorbent assay from venous blood samples from each patient. Results Within the included 56 patients, 30 had benign lesion and 26 (46%) had squamous cell carcinoma (SCC). Overall, 73.3% of patient with benign lesions were seropositive and 92.3% of patient with laryngeal SCC were seropositive. The mean anti-H. pylori IgG antibody level was significantly (P=0.0041) higher in patients who had SCC (23.93±19.6) than patients who had benign laryngeal lesions (38.9±27.5). Conclusion Laryngeal lesions are commonly associated with H. Pylori infection and showed significantly higher level in laryngeal SCC than benign lesions, reflecting more association of larynx cancer with H. pylori infection.
