Factors associated with parietal cell autoantibodies in the general population.

The presence in serum of parietal cell autoantibodies (PCA) is a characteristic of autoimmune gastritis. We determined the prevalence of PCA in the general population and investigate their association with type 2 diabetes, insulin resistance and lifestyle factors related with autoimmune gastritis. A cross-sectional study was performed, involving 429 individuals enrolled in a cohort study of the general population of the Canary Islands. All participants underwent physical examination, provided a blood sample and responded to a questionnaire regarding health and lifestyle factors. Serum concentrations of PCA, soluble CD40 ligand (sCD40L), C-peptide and glucose (to determine insulin resistance) were measured. The association of PCA with the other factors was determined with bivariate analysis, and logistic regression models were used to adjust the associations for age and sex. The prevalence of PCA was 7.8% (95% CI=10.3-5.3). The factors associated with PCA were female sex (p=0.032), insulin resistance (p=0.016), menopause (p=0.029) and sCD40L (p=0.019). Alcohol consumption (p=0.006) and smoking (p=0.005) were associated with low prevalences of PCA. After adjustment for age and sex, the association with PCA was confirmed for smoking (OR=0.1 [0.0-0.9]), alcohol consumption (OR=0.3 [0.1-0.9]), insulin resistance (OR=2.4 [1.1-4.9]), female sex (OR=2.4 [1.1-5.3]), sCD40L (OR=3.7 [1.2-11.4]) and menopause (OR=5.3 [1.2-23.3]). In conclusion, smoking and alcohol consumption acted as protective factors against the appearance of PCA in the general population, whereas female sex, menopause, insulin resistance and elevated serum sCD40L were risk markers for PCA. In patients who smoke or drink alcohol, clinicians should be cautious when using PCA to rule out autoimmune gastritis.

Cardiovascular disease (CVD) is the first cause of death in the Spanish population among both diabetics and non-diabetics. In diabetes, CVD is between 2 and 4 times more frequent, earlier and more aggressive. With current measures, approximately 50% of CVD can be prevented. The risk factors for CVD in diabetes are hypertension, dyslipidemia, smoking, obesity and sedentariness. More than 80% of patient with type 2 diabetes have hypertension and dyslipidemia and approximately 15% continue to smoke. However, all these factors are controlled in at least 10%. Although dyslipidemia is the most influential and least treated factor, the greatest benefit for CVD prevention is obtained with integrated intervention on all risk factors, reducing blood pressure to below 140/80 mmHg, low-density lipoprotein cholesterol (LDL-c) to below 100 mg/dl, encouraging smoking cessation, regular physical activity and maintaining a healthy weight (BMI < 25 kg/m²). In secondary prevention or persons with microvascular disease, the targets may be stricter (blood pressure 130/80 mmHg and LDL-c 80 mg/dl). Drug treatment should always include an angiotensin converting-enzyme inhibitor or an angiotensin II receptor antagonist and a statin. Aspirin should be reserved for patients in secondary prevention or with very high CV risk. Consequently, interventions should be prioritized according to the foreseeable risk for each patient, which can be estimated through the SCORE scale or other scales such as Regicor or UKPDS, with a SCORE > 5% indicating high risk. These high-risk patients should receive personalized care.
