Celiac Disease in the Elderly

Celiac Disease: Beyond Diet and Food Awareness

Celiac disease is attributable to a combination of genetic predisposition and exposure to dietary gluten, with immune system involvement. The incidence is increasing globally, and the societal economic burden of celiac disease stretches beyond the cost of gluten-free food. This enteropathy that affects the small intestine has been related to different disorders and comorbidities. Thus, the implications of suffering from this disease are multidimensional and need further consideration. Celiac disease is a serious condition that remains under-recognized, resulting in an increased need for programs for better management. This review aims to summarize the current evidence regarding celiac diseases, with special emphasis on clinical implications, diagnosis, dietary management, socioeconomical aspects, and future perspectives.

Older Adults With Celiac Disease Are At Increased Risk of Frailty: A Nationwide Cohort Study

INTRODUCTION

Celiac disease (CeD) is increasingly diagnosed in older adults, though few studies have explored complications in this group. As frailty confers increased risk for adverse events, we aimed to explore frailty in older adults with CeD.

METHODS

In a nationwide Swedish cohort, we identified adults ≥60 years with incident CeD between 2004 and 2017 which we matched to population-based controls without CeD by age, sex, county, and calendar-period. Baseline frailty within 3 years before CeD diagnosis or index date was assessed using the Hospital Frailty Risk Score. Among those without baseline frailty, we used conditional logistic regression to estimate odds ratios and 95% confidence intervals of future frailty at 5 years comparing CeD with controls. Logistic regression was used to evaluate the association between persistent villous atrophy vs mucosal healing and frailty in patients with CeD.

RESULTS

A total of 4,646 older adults with CeD were matched to 21,944 non-CeD individuals. Baseline frailty was increased in patients with CeD (54.4%) compared with controls (29.7%, P < 0.001), which existed across all frailty categories: low-risk (43.4% vs 23.8%), intermediate-risk (10.3% vs 5.4%), and high-risk (0.8% vs 0.6%). Among those without baseline frailty, patients with CeD had a 61% increased risk of overall frailty at 5 years (95% confidence interval 1.46-1.78). Mucosal healing in CeD individuals on follow-up biopsy did not protect against future frailty.

DISCUSSION

Older adults with CeD were significantly more likely to become frail than matched comparators. This analysis reveals the increased vulnerability that older patients with CeD are likely to experience.

Patient and Community Health Global Burden in a World With More Celiac Disease

Celiac disease is one of the most common life-long disorders worldwide, with a prevalence mostly ranging between 0.7% and 2.9% in the general population and a higher frequency in females and well-defined at-risk groups, such as relatives of affected individuals and patients with autoimmune comorbidities. Increasing clinical detection is facilitated by improving awareness, implementation of a case-finding approach, and serology availability for screening at-risk patients, among other factors. Nevertheless, due to huge clinical variability, many celiac disease cases still escape diagnosis in most countries, unless actively searched by proactive policies. The burden of celiac disease is increasing, as is the need for better longitudinal care. Pediatric screening of the general population could represent the road ahead for an efficient intervention of secondary prevention aimed to reduce the social and health burden of celiac disease. This review analyses the epidemiology of celiac disease continent by continent, discusses current strategies to improve the detection of celiac disease, and highlights challenges related to the burden of celiac disease globally.

Anemia and Its Connections to Inflammation in Older Adults: A Review

Anemia is a common hematological disorder that affects 12% of the community-dwelling population, 40% of hospitalized patients, and 47% of nursing home residents. Our understanding of the impact of inflammation on iron metabolism and erythropoiesis is still lacking. In older adults, anemia can be divided into nutritional deficiency anemia, bleeding anemia, and unexplained anemia. The last type of anemia might be caused by reduced erythropoietin (EPO) activity, progressive EPO resistance of bone marrow erythroid progenitors, and the chronic subclinical pro-inflammatory state. Overall, one-third of older patients with anemia demonstrate a nutritional deficiency, one-third have a chronic subclinical pro-inflammatory state and chronic kidney disease, and one-third suffer from anemia of unknown etiology. Understanding anemia's pathophysiology in people aged 65 and over is crucial because it contributes to frailty, falls, cognitive decline, decreased functional ability, and higher mortality risk. Inflammation produces adverse effects on the cells of the hematological system. These effects include iron deficiency (hypoferremia), reduced EPO production, and the elevated phagocytosis of erythrocytes by hepatic and splenic macrophages. Additionally, inflammation causes enhanced eryptosis due to oxidative stress in the circulation. Identifying mechanisms behind age-related inflammation is essential for a better understanding and preventing anemia in older adults.
