- OBJECTIVES: Primary adrenocortical insufficiency is mostly caused by an autoimmune destruction of the adrenal cortex. The disease may appear isolated or as a part of an autoimmune polyendocrine syndrome (APS). APS1 is a rare hereditary disorder with a broad spectrum of clinical manifestations. In APS2, primary adrenocortical insufficiency is often combined with autoimmune thyroid disease and/or type 1 diabetes. We analysed mortality and cancer incidence in primary adrenocortical insufficiency patients during 40 years. Data were compared with the general Swedish population. DESIGN AND PATIENTS: A population based cohort study including all patients with autoimmune primary adrenocortical insufficiency (3299) admitted to Swedish hospitals 1964-2004. MEASUREMENTS: Mortality risk was calculated as the standardized mortality ratio (SMR) and cancer incidence as the standardized incidence ratio (SIR). RESULTS: A more than 2-fold increased mortality risk was observed in both women (SMR 2.9, 95% CI 2.7-3.0) and men (SMR 2.5, 95% CI 2.3-2.7). Highest risks were observed in patients diagnosed in childhood. SMR was higher in APS1 patients (SMR 4.6, 95% CI 3.5-6.0) compared with patients with APS2 (SMR 2.1, 95% CI 1.9-2.4). Cancer incidence was increased (SIR 1.3, 95% CI 1.2-1.5). When tumours observed during the first year of follow-up were excluded, only the cancer risk among APS1 patients remained increased. Cause-specific cancer incidence analysis revealed significantly higher incidences of oral cancer, nonmelanoma skin cancer, and male genital system cancer among patients. Breast cancer incidence was lower than in the general population. CONCLUSIONS: Our study shows a reduced life expectancy and altered cancer incidence pattern in patients with autoimmune primary adrenocortical insufficiency.

- Context: Autoimmune Addison's disease(AAD) tends to affect young and middle-aged women. It is not known whether the existence of undiagnosed or diagnosed AAD influences the outcome of pregnancy. Objective: The aim of the study was to compare the number of children and pregnancy outcomes in individuals with AAD and controls. Design and Setting: We conducted a population-based historical cohort study in Sweden. Patients: Through the Swedish National Patient Register and the Total Population Register, we identified 1,188 women with AAD and 11,879 age-matched controls who delivered infants between 1973 and 2006. Main Outcome Measures: We measured parity and pregnancy outcome. Results: Adjusted odds ratios (ORs) for infants born to mothers with deliveries 3 yr or less before the diagnosis of AAD were 2.40 [95% confidence interval (Cl), 1.27-4.53] for preterm birth (<= 37 wk), 3.50 (95% Cl, 1.83-6.67) for low birth weight (<2500 g), and 1.74 (95% Cl, 1.02-2.96) for cesarean section. Compared to controls, women who gave birth after their AAD diagnosis were at increased risk of both cesarean delivery (adjusted OR, 2.35; 95% Cl, 1.68-3.27) and preterm delivery (adjusted OR, 2.61; 95% Cl, 1.69-4.05). Stratifying by isolated AAD and concomitant type 1 diabetes and/or autoimmune thyroid disease in the mother did not essentially influence these risks. There were no differences in risks of congenital malformations or infant death. Women with AAD had a reduced overall parity compared to controls (P < 0.001). Conclusion: Clinically undiagnosed and diagnosed AAD both entail increased risks of unfavorable pregnancy outcomes. AAD also influences the number of childbirths.

- Objectives: Earlier research has suggested a positive association between Addison’s disease (AD) and celiac disease (CD).Wehave here investigated the risk of AD in individuals with CD from a general population cohort.Methods: 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.Results: 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).Conclusions: 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.

- Background: It has been suggested that celiac disease is associated with thyroid disease. Earlier studies, however, have been predominately cross-sectional and have often lacked controls. There is hence a need for further research. In this study, we estimated the risk of thyroid disease in individuals with celiac disease from a general population cohort.Methods: A total of 14,021 individuals with celiac disease (1964–2003) and a matched reference population of 68,068 individuals were identified through the Swedish national registers. Cox regression estimated the risk of thyroid disease in subjects with celiac disease. Analyses were restricted to individuals with a follow-up ofmorethan 1 yr and withnothyroid disease before study entry or within 1 yr after study entry. Conditional logistic regression estimated the odds ratio for subsequent celiac disease in individuals with thyroid disease.Results: Celiac disease was positively associated with hypothyroidism [hazard ratio (HR)_4.4;95% confidence interval (CI) _ 3.4 –5.6; P _ 0.001], thyroiditis (HR _ 3.6; 95% CI _1.9–6.7; P _ 0.001) and hyperthyroidism (HR_2.9;95%CI_2.0–4.2; P_0.001). The highest risk estimates were found in children (hypothyroidism, HR _ 6.0 and 95% CI _ 3.4 –10.6; thyroiditis, HR _ 4.7 and 95% CI _ 2.1–10.5; hyperthyroidism, HR _ 4.8 and 95% CI _ 2.5–9.4). In post hoc analyses, where the reference population was restricted to inpatients, the adjusted HR was 3.4 for hypothyroidism (95% CI_2.7– 4.4; P_0.001), 3.3 for thyroiditis(95%CI_1.5–7.7; P_0.001), and 3.1 for hyperthyroidism (95% CI _ 2.0–4.8; P _ 0.001).Conclusion: Celiac disease is associated with thyroid disease, and these associations were seen regardless of temporal sequence. This indicates shared etiology and that these individuals are more susceptible to autoimmune disease.

- Context: Celiac disease (CD) has been linked to several endocrine disorders, including type 1 diabetes and thyroid disorders, but little is known regarding its association to primary hyperparathyroidism (PHPT).Objective: The aim of the study was to examine the risk of PHPT in patients with CD.Design and Setting: We conducted a two-group exposure-matched nonconcurrent cohort study in Sweden. A Cox regression model estimated hazard ratios (HR) for PHPT.Participants: We identified 17,121 adult patients with CD who were diagnosed through biopsy reports (Marsh 3, villous atrophy) from all 28 pathology departments in Sweden. Biopsies were performed in 1969-2008, and biopsy report data were collected in 2006-2008. Statistics Sweden then identified 85,166 reference individuals matched with the CD patients for age, sex, calendar period, and county.Main Outcome Measure: PHPT was measured according to the Swedish national registers on inpatient care, outpatient care, day surgery, and cancer.Results: During follow-up, 68 patients with CD and 172 reference individuals developed PHPT(HR = 1.91; 95% confidence interval = 1.44-2.52). The absolute risk of PHPT was 42/100,000 person-years with an excess risk of 20/100,000 person-years. The risk increase for PHPT only occurred in the first 5 yr of follow-up; after that, HR were close to 1 (HR = 1.07; 95% confidence interval = 0.70-1.66).Conclusions: CD patients are at increased risk of PHPT, but the absolute risk is small, and the excess risk disappeared after more than 5 yr of follow-up.

- Background: In earlier studies based on selected populations, the relative risk for thyroid cancer in celiac disease has varied between 0.6 and 22.5. We aimed to test this relationship in a population-based setting. Methods: We collected small intestinal biopsy report data performed in 1969-2008 from all 28 Swedish pathology departments. 29,074 individuals with celiac disease (villous atrophy; Marsh histopathology stage III) were matched for sex, age, calendar year, and county to 144,440 reference individuals from the Swedish general population. Through Cox regression, we then estimated hazard ratios (HRs) and confidence intervals (CIs) for any thyroid cancer and papillary thyroid cancer (defined according to relevant pathology codes in the Swedish Cancer Register) in patients with celiac disease. Results: During follow-up, any thyroid cancer developed in seven patients with celiac disease (expected = 12) and papillary thyroid cancer developed in five patients (expected = 7). Celiac disease was not associated with an increased risk of any thyroid cancer (HR 0.6 [CI 0.3-1.3]) or of papillary thyroid cancer (HR 0.7 [CI 0.3-1.8]). All cases of thyroid cancer in celiac disease occurred in female patients. Risk estimates were similar before and after the year 2000 and independent of age at celiac diagnosis (<= 24 years vs. >= 25 years). Conclusions: We conclude that, in the Swedish population, there is no increased risk of thyroid cancer in patients with celiac disease. This differs from what has been reported in smaller studies in Italy and the United States.
