Summary
POEMS syndrome, a rare condition, frequently involves hypothyroidism. This study found a strong link between hypothyroidism and fluid overload (edema/effusions) in POEMS patients, with treatment improving both.
Area of Science:
- Endocrinology
- Neurology
- Rare Diseases
Background:
- POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M protein, skin changes) is a rare multisystem disorder.
- Endocrinopathy, particularly hypothyroidism, is a key feature of POEMS syndrome.
- Limited data exists on thyroid function's clinical significance in POEMS syndrome.
Purpose of the Study:
- To investigate thyroid function in POEMS syndrome patients.
- To analyze the association between hypothyroidism and clinical manifestations, specifically edema/effusions.
- To evaluate the impact of treatment on these conditions.
Main Methods:
- Retrospective analysis of 24 POEMS syndrome cases.
- Assessment of thyroid function tests (clinical and subclinical hypothyroidism).
- Correlation analysis between hypothyroidism and extravascular volume overload (edema/effusions).
Main Results:
- 17 out of 24 (70.8%) POEMS patients had hypothyroidism (11 clinical, 6 subclinical).
- 14 out of 24 (58.3%) patients exhibited edema/effusions.
- 12 of the 14 patients with edema/effusions were hypothyroid, suggesting a link.
Conclusions:
- Hypothyroidism is highly prevalent in POEMS syndrome.
- Hypothyroidism may contribute to edema and effusions in POEMS syndrome.
- Thyroid hormone replacement and chemotherapy effectively improved hypothyroidism and fluid overload symptoms.

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...
01:24Graves 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...
01:25Hyperthyroidism 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...
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...
01:28Graves' 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...
01:18Functions of Thyroid Hormones
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
