Insights
Helicobacter pylori infection is linked to increased arterial stiffness in young adults, indicated by higher pulse-wave velocity. This association diminishes with age, suggesting H. pylori may play a role in early arteriosclerosis development.
Area of Science:
- Cardiovascular Health
- Infectious Diseases
- Gerontology
Background:
- Helicobacter pylori infection is associated with cardiovascular diseases.
- The specific link between H. pylori and arteriosclerosis requires further investigation.
Purpose of the Study:
- To investigate the role of H. pylori infection in the development of arteriosclerosis.
Main Methods:
- Cross-sectional study of 996 individuals undergoing medical check-ups.
- Assessed H. pylori infection status via serum antibodies.
- Measured blood lipids, glucose, and arteriosclerotic parameters (SBP, ABI, PWV).
Main Results:
- H. pylori-seropositive individuals showed significantly lower high-density lipoprotein cholesterol (HDLC) levels.
- No overall differences in systolic blood pressure (SBP) or ankle-brachial index (ABI).
- Higher pulse-wave velocity (PWV) observed in H. pylori-seropositive young individuals (<39 years).
Conclusions:
- Arterial stiffness, measured by PWV, is greater in young H. pylori-positive subjects.
- This difference in arterial stiffness is not observed in elderly individuals.
- H. pylori infection may contribute to early-stage arteriosclerosis in younger populations.
Background:
Helicobacter pylori infection has been reported to correlate with the onset of cardiovascular diseases. However, the relationship between H. pylori infection and the development of arteriosclerosis has not been fully investigated. We performed a cross-sectional study to clarify the possible role of H. pylori infection in the development of arteriosclerosis.
Methods:
The subjects were 996 cases who attended their annual medical check-up between April and August 2001. H. pylori infection status was determined by assaying serum anti-H. pylori immunoglobulin G antibodies. Total cholesterol, high-density lipoprotein cholesterol (HDLC), triglyceride, fasting blood glucose, hemoglobin A1c and leukocyte levels were determined. Arteriosclerotic parameters (systolic blood pressure (SBP), ankle brachial index (ABI) and pulse-wave velocity (PWV)) were measured non-invasively using an automatic device. The data for H. pylori-seropositive and -seronegative individuals were compared.
Results:
Five hundred and seventy-three subjects (57.5%) were H. pylori-seropositive. After adjustment for sex, age, body mass index, and smoking and drinking habits, the HDLC levels of the seropositive and seronegative groups differed markedly (55.0 vs 58.0 mg/dL, P < 0.0001). Although there were no differences between the overall adjusted SBP and ABI values, the PWV was higher in H. pylori-seropositive than -seronegative young (<39 years old) individuals (heart-carotid PWV: 632.2 vs 589.7 cm/s, P = 0.027). These differences tended to disappear with aging.
Conclusions:
The degree of arterial stiffness in H. pylori-positive young subjects is higher than that in H. pylori-negative young subjects. However, no difference between the arterial stiffness values of H. pylori-seropositive and -seronegative elderly individuals was observed.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
