Cardiomyopathy II: Dilated Cardiomyopathy

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Graves' Disease I: Introduction

Graves' 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...

Graves Disease II: Pathophysiology

Graves 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...

Cushing Syndrome I: Introduction

Cushing Syndrome I: Introduction

Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...

Cushing Syndrome II: Pathophysiology

Cushing 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...

Huntington Disease l: Introduction

Huntington 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,...

Summary

Vogt-Koyanagi-Harada syndrome, a rare inflammatory condition, affects multiple systems. This study highlights three non-Asian cases, suggesting an autoimmune basis and guiding treatment strategies.

Area of Science:

Immunology
Ophthalmology
Neurology

Background:

Vogt-Koyanagi-Harada (VKH) syndrome is a rare multisystem inflammatory disorder affecting ocular, neurological, auditory-vestibular, and integumentary systems.
While more prevalent in Asia, VKH syndrome is also observed in European populations.

Observation:

Three non-Asian patients presented with bilateral panuveitis and hearing loss (hypoacusia).
Associated symptoms included peripheral facial palsy (2 patients), vestibular syndrome (2 patients), and lymphocytic meningitis (1 patient).
Characteristic HLA II typing was identified in all cases, with one patient exhibiting auto-antibodies against retina, choroid, and cochlea.

Findings:

Treatment involved corticosteroids, with cyclophosphamide added for persistent symptoms.

Two patients experienced favorable visual outcomes, while one had auditory sequelae.

The presence of specific auto-antibodies supports an autoimmune etiology.

Implications:

These findings contribute to understanding the autoimmune pathogenesis of Vogt-Koyanagi-Harada syndrome.
The study underscores the importance of early diagnosis and multimodal treatment approaches.
Further research into the autoimmune mechanisms of VKH syndrome is warranted.
