Earlier research has suggested a positive association between Addison's disease (AD) and celiac disease (CD). We have here investigated the risk of AD in individuals with CD from a general population cohort.
Through the Swedish national registers we identified 14,366 individuals with a diagnosis of CD (1964-2003) and 70,095 reference individuals matched for age, sex, calendar year, and county of residence. We used Cox regression to estimate hazard ratios (HRs) for subsequent AD. Analyses were restricted to individuals with more than 1 yr of follow-up and without AD prior to study entry or within 1 yr after study entry. Conditional logistic regression estimated the odds ratio for CD in individuals with prior AD.
There was a statistically significantly positive association between CD and subsequent AD [HR = 11.4; 95% confidence interval (CI) = 4.4-29.6]. This risk increase was seen in both children and adults and did not change with adjustment for diabetes mellitus or socioeconomic status. When we restricted reference individuals to inpatients, the adjusted HR for AD was 4.6 (95% CI = 1.9-11.4). Individuals with prior AD were at increased risk of CD (odds ratio = 8.6; 95% CI = 3.4-21.8).
This study found a highly increased risk of AD in individuals with CD. This relationship was independent of temporal sequence. We therefore recommend that individuals with AD should be screened for CD. We also suggest an increased awareness of AD in individuals with CD.
"Conversely, this association was also confirmed, showing an increased risk of developing Addison's disease among celiac patients (HR 11.4; 95% CI, 4.4–29.6) , and it has been described that GFD does not modify the natural history of Addison's disease . "
[Show abstract][Hide abstract] ABSTRACT: Celiac disease (CD) is frequently accompanied by a variety of extradigestive manifestations, thus making it a systemic disease rather than a disease limited to the gastrointestinal tract. This is primarily explained by the fact that CD belongs to the group of autoimmune diseases. The only one with a known etiology is related to a permanent intolerance to gluten. Remarkable breakthroughs have been achieved in the last decades, due to a greater interest in the diagnosis of atypical and asymptomatic patients, which are more frequent in adults. The known presence of several associated diseases provides guidance in the search of oligosymptomatic cases as well as studies performed in relatives of patients with CD. The causes for the onset and manifestation of associated diseases are diverse; some share a similar genetic base, like type 1 diabetes mellitus (T1D); others share pathogenic mechanisms, and yet, others are of unknown nature. General practitioners and other specialists must remember that CD may debut with extraintestinal manifestations, and associated illnesses may appear both at the time of diagnosis and throughout the evolution of the disease. The implementation of a gluten-free diet (GFD) improves the overall clinical course and influences the evolution of the associated diseases. In some cases, such as iron deficiency anemia, the GFD contributes to its disappearance. In other disorders, like T1D, this allows a better control of the disease. In several other complications and/or associated diseases, an adequate adherence to a GFD may slow down their evolution, especially if implemented during an early stage.
"This disease is triggered by gluten exposure in genetically sensitive individuals. Earlier research suggests that CD is associated with a number of autoimmune diseases (Collin et al., 2002; Ludvigsson et al., 2006; Elfstrom et al., 2007, 2008; Neuhausen et al., 2008). Psoriasis is a chronic autoimmune skin disease. "
[Show abstract][Hide abstract] ABSTRACT: Earlier studies on the association between celiac disease (CD) and psoriasis show contradictory results. The purpose of this study was to assess the risk of psoriasis in patients with biopsy-verified CD. Through 28 pathology departments in Sweden, we identified individuals with CD diagnosed between 1969 and 2008 (Marsh 3: villous atrophy; n = 28,958 unique individuals). We then used Cox regression to compare individuals with CD with 143,910 sex- and age-matched controls regarding their risk of psoriasis. CD was a risk factor for future psoriasis (hazard ratio (HR) = 1.72; 95% confidence interval (CI) = 1.54-1.92; during follow-up, 401 individuals with CD and 1,139 controls had a diagnosis of psoriasis). The absolute risk of future psoriasis in patients with CD was 135/100,000 person-years (excess risk = 57/100,000). In all, 42% of all psoriasis in patients with CD could be attributed to the underlying CD. Moreover, in children we saw a positive association between CD and psoriasis (HR = 2.05; 95% CI = 1.62-2.60). The association between CD and psoriasis seems to be independent of a temporal relationship, as we also found a positive association between CD and psoriasis before CD diagnosis (odds ratio = 1.91; 95% CI = 1.58-2.31). In conclusion, individuals with CD were at increased risk of psoriasis both before and after CD diagnosis.
