Summary
Graves' disease relapse complicated by immune thrombocytopenia (ITP) was successfully treated with a thrombopoietin-receptor-agonist. Normalizing thyroid function also normalized platelet counts, suggesting a link between the conditions.
Area of Science:
- Endocrinology
- Hematology
- Immunology
Background:
- Graves' disease is an autoimmune disorder affecting the thyroid.
- Immune thrombocytopenia (ITP) is characterized by low platelet counts due to immune destruction.
- Co-occurrence of Graves' disease and ITP presents complex management challenges.
Observation:
- A patient with relapsed Graves' disease presented with severe immune thrombocytopenia (ITP).
- Standard ITP treatments including glucocorticoids, immunoglobulins, and rituximab were ineffective.
- Bone marrow examination revealed increased megakaryocytes, consistent with ITP.
Findings:
- Treatment with a thrombopoietin-receptor-agonist led to successful normalization of platelet counts.
- Resolution of Graves' disease through thyrostatic therapy correlated with normalized platelet counts.
- Platelet normalization persisted even after discontinuation of ITP-specific treatment.
Implications:
- Thrombopoietin-receptor-agonists are effective for refractory ITP.
- Effective management of Graves' disease may positively impact ITP in co-occurring cases.
- Splenectomy should be considered cautiously in patients with coexisting Graves' disease and ITP.

01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:28Graves' Disease I: Introduction
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...
01:24Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:23Hypothyroidism II: Pathophysiology
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
01:25Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
