Impaired Quality of Life in Patients with Autoimmune Atrophic Gastritis.

BACKGROUND: Autoimmune atrophic gastritis (AAG) leads to vitamin B12 deficiency that may manifest with neuropsychiatric disorders, such as emotional instability, cognitive deficits, depression, and personality changes. AIMS: To evaluate the quality of life (QoL) in patients with AAG and the interplay between QoL, psychopathological symptoms, and demographic factors. METHODS: This is an observational, cross-sectional study including 102 patients with AAG (mean age 62 ± 13 years), 100 with functional gastrointestinal disorders (mean age 38.3 ± 17 years), 100 with other chronic organic gastrointestinal diseases (mean age 50.9 ± 21.4 years), and 100 healthy controls (mean age 37.5 ± 18.9 years). The 36-Item Short Form Health Survey questionnaire (SF-36) and the General Health Questionnaire-12 were administered. The results of the scales were compared among the study groups. Linear regression analyses were fitted to identify independent predictors of QoL in AAG patients. RESULTS: QoL was significantly different among the four groups in all subdomains. In particular, the AAG group was significantly (P < 0.01) more impaired than the functional gastrointestinal disorder group in the physical functioning and it was significantly more impaired than the control group in all the quality of life subdomains with exception of vitality. Vitamin B12 serum level was a significant (P < 0.04) independent predictor of physical functioning. CONCLUSIONS: Patients with AAG have a decreased QoL compared to healthy controls, but in line with that of patients with organic gastrointestinal disorders. Physical component is responsible for worsening QoL. Vitamin B12 supplementation may positively affect patient's perception of body functioning.

Mortality rate and risk factors for gastrointestinal bleeding in elderly patients.

BACKGROUND: Gastrointestinal bleeding (GIB) is burdened by high mortality rate that increases with aging. Elderly patients may be exposed to multiple risk factors for GIB. We aimed at defining the impact of GIB in elderly patients. METHODS: Since 2008, samples of elderly patients (age ≥ 65 years) with multimorbidity admitted to 101 internal medicine wards across Italy have been prospectively enrolled and followed-up (REPOSI registry). Diagnoses of GIB, length of stay (LOS), mortality rate, and possible risk factors, including drugs, index of comorbidity (Cumulative Illness Rating Scale [CIRS]), polypharmacy, and chronic diseases were assessed. Adjusted multivariate logistic regression models were computed. RESULTS: 3872 patients were included (mean age 79 ±â€¯7.5 years, F:M ratio 1.1:1). GIB was reported in 120 patients (mean age 79.6 ±â€¯7.3 years, F:M 0.9:1), with a crude prevalence of 3.1%. Upper GIB occurred in 72 patients (mean age 79.3 ±â€¯7.6 years, F:M 0.8:1), lower GIB in 51 patients (mean age 79.4 ±â€¯7.1 years, F:M 0.9:1), and both upper/lower GIB in 3 patients. Hemorrhagic gastritis/duodenitis and colonic diverticular disease were the most common causes. The LOS of patients with GIB was 11.7 ±â€¯8.1 days, with a 3.3% in-hospital and a 9.4% 3-month mortality rates. Liver cirrhosis (OR 5.64; CI 2.51-12.65), non-ASA antiplatelet agents (OR 2.70; CI 1.23-5.90), and CIRS index of comorbidity >3 (OR 2.41; CI 1.16-4.98) were associated with GIB (p < 0.05). CONCLUSIONS: A high index of comorbidity is associated with high odds of GIB in elderly patients. The use of non-ASA antiplatelet agents should be discussed in patients with multimorbidity.

Natural history of autoimmune atrophic gastritis: a prospective, single centre, long-term experience.

BACKGROUND: Autoimmune atrophic gastritis (AAG) is an immune-mediated disorder characterised by destruction of gastric oxyntic mucosa AIM: To explore gastric histopathological evolution in a cohort of AAG patients over a prolonged follow-up METHODS: Single centre prospective study enrolling consecutive patients with histologically confirmed AAG between 2000 and 2018. All AAG patients undergoing endoscopic follow-up every 1-3 years were classified as having stages 1, 2 or 3 according to atrophy severity (mild, moderate and severe). AAG patients with either glandular or neuroendocrine dysplasia/neoplasia were classified as having stage 4. Disease stage progression, and changes in serum anti-parietal cell antibody (PCA), chromogranin A and gastrin-17 were assessed. RESULTS: In total, 282 AAG patients (mean age 60.3 years; F:M ratio 2.4:1; median follow-up 3 years, interquartile range 1-7) were enrolled. All patients with stages 1 or 2 progressed to stage 2 or 3 over time with a steady trend (P = .243) and regression from a severe to a milder stage was never noticed. Disease progression of patients with stages 1 or 2 occurred within the first 3 years. PCA positivity rate did not change over time. Stage 3 patients had higher gastrin-17 levels compared to patients with stages 1 and 2 (median 606 vs 295 pg/mL; P < .001). In stage 3, the hazard ratio for the risk of developing stage 4 was 6.6 (95% CI 1.5-29; P = .001). CONCLUSIONS: AAG is a steadily progressive disease, in which stages 1 and 2 always progress to stage 3. The risk of developing a complicated disease stage is greater in patients with more severe gastric lesions.
