Summary
Thrombocytopenia in sarcoidosis is uncommon but can result from hypersplenism, bone marrow granulomas, or immune causes. Corticosteroids are the primary effective treatment for this rare hematological manifestation.
Area of Science:
- Hematology
- Immunology
- Pulmonology
Background:
- Hematological manifestations in sarcoidosis are rare.
- The prevalence of thrombocytopenia in sarcoidosis requires further assessment.
Observation:
- Two personal cases of sarcoidosis-associated thrombocytopenia were described.
- A literature review identified 31 cases from 1972 onwards.
Findings:
- Mechanisms include hypersplenism (10 cases), bone marrow granulomas (4 cases), and immune thrombocytopenic purpura (suspected in others).
- Corticosteroids were effective in 21 of 23 treated patients.
- Splenectomy was successful in 4 of 7 cases, and intravenous immunoglobulin (IV-Ig) led to complete response in 4 of 5 patients.
Implications:
- Thrombocytopenia in sarcoidosis has diverse etiologies.
- Corticosteroids are the recommended first-line treatment.
- Early recognition and management are crucial for patient outcomes.

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...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
01:21Cytotoxic Edema: Pathophysiology
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
01:24Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
