Summary
Vogt-Koyanagi-Harada syndrome (VKHS) is a rare autoimmune disease affecting melanin-rich tissues. Current treatments involve corticosteroids, but immunomodulatory therapy is crucial for managing VKHS.
Area of Science:
- Ophthalmology
- Immunology
- Genetics
Background:
- Vogt-Koyanagi-Harada syndrome (VKHS) is a rare multisystemic autoimmune disorder targeting melanin-containing tissues.
- It presents with uveitis, auditory, neurological, and cutaneous symptoms, predominantly in individuals with darker pigmentation.
Purpose of the Study:
- To review current knowledge on the aetiopathogenesis of VKHS, including viral, genetic, and immune mechanisms.
- To discuss the pathogenesis and its implications for pharmacotherapy.
Main Methods:
- Systematic review of publications from 1965 to 2012.
- Analysis focused on aetiopathogenesis and pharmacotherapy of VKHS.
Main Results:
- VKHS is a T-cell-mediated autoimmune process against melanocytes, with unknown exact cause.
- Genetic factors, particularly HLA-DRB1*0405, play a role in susceptibility.
- Classic symptoms include panuveitis, hearing loss, meningitis, and skin manifestations.
Conclusions:
- Corticosteroids remain the primary initial therapy for VKHS.
- Recurrent attacks and steroid complications necessitate non-steroid immunomodulatory therapy (IMT).

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...
01:24Graves 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...
01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
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...
01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
01:43Sex-linked Disorders
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
