- Introduction: In gender-skewed conditions such as Graves' disease (GD), the outcome naturally becomes dominated by the majority. This may lead to gender-biased misunderstandings regarding treatment outcomes. This especially holds true when complications, such as depression, are unevenly distributed. We have, therefore, studied the long-term outcome of GD from a gender perspective.Materials and Methods: A cohort of 1186 patients with GD was included in a follow-up 6-10 years after inclusion. Choice of treatment, the feeling of recovery, long-term treatment, comorbidity, and quality of life were investigated with questionnaires. All results were studied sex-divided.Results: We included 973 women and 213 men. There was no difference between men and women in the choice of treatment. At follow-up, women scored significantly worse in the general questionnaire 36-item Short-Form Health Status (SF-36) domain bodily pain and in the thyroid-specific Thyroid-Related Patient-Reported Outcome (ThyPRO) domains depression, impaired sex life, and cosmetic complaints, all p < 0.05. Women were twice as likely (29.5%) to be treated with levothyroxine after successful treatment with antithyroid drugs (ATD) compared with men (14.9%, p < 0.05).Conclusion: After treatment for GD, women were more affected by depression, impaired sex life, cosmetic issues, and bodily pain despite successful cure of hyperthyroidism. The prevalence of hypothyroidism was also doubled in women. Whether these observed gender differences reflect a worse outcome of GD in women or a natural consequence of a higher prevalence of these symptoms and autoimmunity in the female population is difficult to disentangle. Nevertheless, several years after GD, women reveal more persistent symptoms.

- Fetal goiter was detected by routine ultrasound in early pregnancy, gestational week (GW) 18, in a 28-year-old woman with no thyroid history, normal thyroid hormone levels and no TSH receptor or thyroid peroxidase antibodies. An umbilical cord blood sample was drawn in GW 23. The analysis indicated fetal hypothyroidism with TSH >100 mU/l (reference value 6.8 ± 2.9, mean ± SD), fT4 3.8 pmol/l (reference value 16.5 ± 5.3, mean ± SD). Intra-amniotic injections of thyroxine were given in conjunction with ultrasound every 7-10 days, in total nine times during GW 24-33. A dose of 10 µg thyroxine/kg of estimated fetal weight per day was administered on six occasions, and 5 µg/kg/day the last three times. Upon injections of thyroxine further growth of the goiter was reduced. Elevated amniotic TSH levels fell from 13 to 2.5 mU/l (reference range 0.04-0.51). Throughout pregnancy, fetal heart rate and skeletal maturation were within normal limits. In week 34, chorioamnionitis was suspected and the child was delivered by cesarean section. Cord blood revealed TSH 596 mU/l (reference value 8.0 ± 5.12, mean ± SD), fT4 4.4 pmol/l (reference value 19.3 ± 4.3, mean ± SD) and total T3 1.18 nmol/l (reference value 0.5 ± 0.3, mean ± SD); the newborn was put on thyroxine supplementation. Psychomotor development of the child, now 3 years old, has been uneventful. The reported experience of treating dyshormonogenetic fetal goiter is limited but growing, creating a need for guidelines on administration of intra-amniotic thyroxine and monitoring treatment.

- Objectives TSH-receptor antibodies (TRAb) targeting the TSH receptor (TSH-R) induce hyperthyroidism in Graves´ disease (GD). Graves´ orbitopathy (GO) is influenced by stimulation of the TSH-R in the orbita. GO has been, among other factors, linked to high TRAb levels. Thyroid stimulating immunoglobulins (TSI) is a relatively new method for assessing TSH-receptor antibodies. The aim of this study was to investigate the role of TSI in the management of GO.Methods Patients with newly diagnosed GD (n=30, median age 55 years (range 35–72), 29 women) received pharmacological therapy (methimazole+++thyroxine) for up to 24 months. GO was identified by clinical signs and symptoms. Eleven patients had GO at diagnosis, and another six developed GO during treatment. Blood samples for TSI and other thyroidal biomarkers were obtained at baseline and on five occasions during the 24-month follow-up. Twenty-two subjects completed the drug regimen without surgery or radioiodine treatment.Results At baseline, TSI was highly correlated with TRAb (r s =0.64, p<0.001), and both assays similarly correlated to fT3 values. TSI and TRAb did not differ significantly between GO and non-GO patients for visit v1 (n=30, 17 GO during the whole study) or at follow-up (n=22, 12 GO during the whole study). During follow-up, levels of TSI and TRAb decreased and normalized in both groups.Conclusion The present study does not support any added benefit of TSI compared to TRAb for the prediction and management of GO.

- Background: Population-based studies have indicated an increase in bone turnover in hyperthyroidism with a subsequent decrease in bone mineral density and an increased risk of fractures, especially in postmenopausal women. However, heterogeneity between studies prevents a definitive conclusion. Graves' disease (GD) is an autoimmune disease, and it is the most common cause of hyperthyroidism. The aim of this study was to investigate fracture risk in patients with GD. Methods: A total of 2134 patients with incident GD and 21,261 age, sex- and county-matched controls were included 16-18 years after diagnosis in a retrospective cohort study. Drug and patient national registries in Sweden were used to assess the risk of developing skeletal complications. Up to 10 years of age, sex- and county-matched controls per patient were selected from databases from the National Board of Health and Welfare and Statistics Sweden. Cox proportional hazards models were fitted to estimate hazard ratios (HR) and confidence intervals [CI]. Results: There were no significant differences in fracture rates between GD and controls but after adjustment for comorbidities, the data showed higher vertebral fracture rates in male GD patients aged >52 years compared to male controls, HR=2.83 [CI 1.05-7.64]. The rates of osteoporosis treatments as well as treatment with corticosteroids were higher in patients with GD. However, HR for the association between GD and fractures remained largely unchanged after adjustment for osteoporosis treatments and treatments with corticosteroids. Conclusions: There were no significant differences in total fracture rate between GD and the general population. However, men older than 52 years had a higher vertebral fracture rate. This study also shows that patients with treated GD receive more osteoporosis treatments compared to the general population.

Graves' Disease; Aspects on Orbitopathy and Bone Metabolism
- 2023

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Graves' disease (GD) is an autoimmune disorder that affects the thyroid gland, with an annual incidence of 21 in 100,000 individuals in Sweden. Graves' orbitopathy (GO) is relatively common in GD and affects 50% of all patients to varying degrees of severity, with severe forms affecting 3–5% of patients. Early diagnosis and treatment of GO are crucial to avoid developing complications from the severe forms of GO. Diagnosis and treatment of GO are still challenging in many complicated cases; thus, new biomarkers are required for improved management. Thyroglobulin (Tg) is a glycoprotein produced by the follicular cells in the thyroid gland whose connection to GO has not been clarified. Measurement of thyroid stimulating immunoglobulins (TSI) is described as a more precise method than the traditional third-generation immunoassay of TSH receptor antibodies (TRAb), for improved diagnosis and management of GD. Vitamin D and bone health in GD have been investigated in different studies with conflicting results. This thesis aimed to explore the role of new biomarkers in the management of GO and to study the impact of GD on bone health. In Papers I–III, we studied 30 consecutive patients with de novo GD. Our studies show that higher levels of Tg are associated with a higher risk of developing GO. However, TSI was highly correlated to TRAb in GD, and it was not more precise than TRAb in the management of GO. No vitamin D deficiency was observed, but data confirm that hyperthyroidism has a negative effect on bone health. During treatment of GD, bone health improved over a two-year follow-up period. In Paper IV, a total of 2,134 patients with GD were included in an investigation 16–18 years after inclusion regarding the risk of developing skeletal complications. There were no increased fracture rates in patients with GD compared to up to ten controls from the general population. However, male patients older than 52 years may have an increased risk of vertebral fractures.

- BACKGROUND: Management of Graves' ophthalmopathy (GO) is still a challenge in Graves' disease (GD). Moreover, 40% of GD patients show radiological muscle enlargement without clinically apparent GO. Delayed treatment of GO may lead to deterioration in prognosis.METHODS: Thirty GD patients with overt hyperthyroidism were included in this study, 17 of whom either had GO at diagnosis or developed GO during the study period. Samples were collected at the beginning of the study, at 6 months, and at 24 months. Plasma samples were analyzed for 92 cytokines using the Olink Target 96 inflammation panel.RESULTS: After adjustment for multiplicity testing using the false discovery rate approach, soluble programmed death ligand 1 (sPD-L1) and fibroblast growth factor 23 (FGF-23) were significantly elevated in GO patients.CONCLUSION: Using a broad cytokine panel we show that patients with Graves' ophthalmopathy have elevated PD-L1 and FGF-23 levels. The findings support previous suggestions that PD-L1 may serve as a treatment target.

- Purpose Serum thyroglobulin levels are often elevated in Graves' disease (GD) and in most cases decrease during treatment. Its relation to Graves' orbitopathy (GO) has not been clarified. Previously, a risk of GO has been linked to smoking, TSH receptor stimulation, high TSH-receptor antibodies (TRAb), low thyroid peroxidase and thyroglobulin antibodies (TPOAb, TgAb). Methods We examined Tg levels in 30 consecutive patients with GD were given drug therapy (methimazole + thyroxine) for up to 24 months. GO was identified by clinical signs and symptoms. 17 patients had GO, 11 of whom had it at diagnosis while 6 developed GO during treatment. During the study, 5 subjects were referred to radioiodine treatment, 3 to surgery. The remaining 22 subjects (GO n = 12, non-GO n = 10) completed the drug regimen. Results At diagnosis, Tg levels in GO patients (n = 11) were higher (84, 30-555 mu g/L, median, range) than in non-GO patients (n = 19) (38, 3.5-287 mu g/L), p = 0.042. Adding the 6 subjects who developed eye symptoms during treatment to the GO group (n = 17), yielded p = 0.001 vs. non-GO (n = 13). TRAb tended to be higher, while TPOAb and TgAb tended to be lower in the GO group. For the 22 patients who completed the drug regimen, Tg levels were higher in GO (n = 12) vs. non-GO (n = 10), p = 0.004, whereas TRAb levels did not differ. Conclusion The data may suggest that evaluation of thyroglobulin levels in GD could contribute to identify patients at increased risk of developing GO. Possibly, thyroidal release of Tg in GD reflects a disturbance that also impacts retroorbital tissues.

- Purpose Vitamin D and osteoporosis in Graves' disease (GD) have been examined in cross-sectional studies with divergent results. Here, we prospectively studied vitamin D metabolism and bone health in patients with newly diagnosed GD. Methods Thirty consecutive patients with de novo overt thyrotoxicosis diagnosed with GD were included. At diagnosis, none of the patients were treated with vitamin D or anti-osteoporotic drugs. All patients were initially treated with antithyroid drugs. Blood samplings were taken at baseline and at 6 weeks, 3, 6, 12 and 24 months after treatment start. Serum levels of 25OHD3, 1,25OH2D3, calcium, parathyroid hormone (PTH), and C-terminal telopeptides of Type I collagen (CTX-I) were analysed. Bone mineral density (BMD) was measured at baseline, and 1 and 2 years after treatment initiation. Results At diagnosis, patients with GD did not have vitamin D deficiency. There were no significant correlations between levels of 25OHD3 and thyrotoxicosis. Upon treatment of the thyrotoxicosis, serum calcium fell transiently, and PTH and 1,25OH2D3 increased. 25OHD3 fell within the normal range and stabilised at 6 months. CTX-I fell over 12 months, BMD increased significantly up to 2 years, p = 0.002, < 0.001 and 0.005 in the spine, left total hip and left femoral neck, respectively. Conclusions The present data underline that thyrotoxicosis has a negative impact on bone health and demonstrate fine-tuned dynamics in bone and vitamin D metabolism. Upon treatment, bone health improved over a follow-up period of 24 months despite rising PTH. Increased conversion of 25OHD3 to 1,25OH2D3 occurs during treatment of GD.
