Autoimmune thyroiditis (AIT) is not only one of the most prevalent human autoimmune diseases, but also the most frequent cause of primary hypothyroidism. It is characterized by lymphocytic infiltration of the thyroid gland with subsequent gradual destruction and fibrous replacement of thyroid tissue. Genetic predisposition, epigenetic modifications and environmental factors are suspected as disease triggers. ⋯ It not only depends on the level of TSH-elevation, but also on other factors, such as patient age, presence of comorbidities and clinical symptoms of hypothyroidism. In contrast, overt hypothyroidism and subclinical hypothyroidism with a TSH-level > 10 mIU/L is a strong indication for LT4 administration, aiming at rapid achievement of euthyroidism. In patients with dissatisfaction due to persistence of symptoms despite optimal LT4-treatment LT4/T3-combination therapy should be considered, based on expert opinion.

Thyroid dysfunctions are common endocrine disorders. With an increasing number of older persons in European societies, the number of older patients affected will also rise. The physiology of thyroid hormones and their regulation change with increasing age. ⋯ Patients older than 65 years with subclinical hypothyroidism and a TSH level > 10 mU/l should also be treated, in particular when cardiovascular comorbidities are present. Levothyroxine treatment has to be monitored on a regular basis, as overdosing is also harmful. For patients with TSH concentrations between 7 and 10 mU/l there is no clear indication to initiate a levothyroxine treatment, as they do not have a clearly elevated mortality and morbidity, also quality of life does not improve.

[The impact of immunosuppression and chronic kidney disease on immunogenicity of COVID-19 vaccines].
HOW EFFECTIVE ARE THE APPROVED VACCINES IN KIDNEY DISEASES AND THOSE RECEIVING IMMUNOSUPPRESSION?: Several observational studies indicated that immunosuppression is associated with a weakened or absent humoral response. Patients with chronic kidney diseases or undergoing maintenance dialysis without immunosuppression have a reduced humoral response to COVID-19 vaccines. I HAD COVID-19. ⋯ AFTER THE FIRST SERIES OF VACCINATION, NO OR ONLY A MARGINAL AMOUNT OF ANTIBODIES WERE DETECTABLE. ARE THERE STRATEGIES TO IMPROVE VACCINE RESPONSE?: Many countries recommend the application of a third dose for vulnerable patient cohorts, especially because of a weakened response and their risk to develop a severe disease course of COVID-19. Prospective clinical trials are ongoing to test the ideal strategy to improve vaccine response in these cohorts.

Graves' orbitopathy (GO) is an autoimmune orbital disease which is mostly associated with Graves' disease and requires good interdisciplinary cooperation. To minimize irreversible damages a stage-adapted anti-inflammatory therapy is of great importance. ⋯ The current concept for Graves' orbitopathy is as follows: first anti-inflammatory therapy then surgical correction of the permanent defects. This might be modified in the future, due to the promising effects of targeted therapies.
