Summary
Systemic autoimmune diseases (SAD) are relevant in sudden sensorineural hearing loss (SNHL). This study found 3.83% of SNHL patients had SAD, often with severe, unilateral, and profound hearing loss, but showed poor treatment response.
Area of Science:
- Otolaryngology
- Rheumatology
- Immunology
Background:
- Sudden sensorineural hearing loss (SNHL) is linked to systemic autoimmune diseases (SAD).
- Immune-mediated SNHL can be unilateral initially, affecting the other ear later.
- Early treatment offers a chance for reversible SNHL in immune-mediated cases.
Purpose of the Study:
- Describe clinical and audiological findings in patients with idiopathic SNHL and SAD.
- Identify probable immune-mediated SNHL cases.
- Estimate the prevalence of SAD in patients presenting with sudden SNHL.
Main Methods:
- Observational retrospective cohort study.
- Inclusion of patients diagnosed with SAD.
- Literature review of scientific repositories.
Main Results:
- 339 patients with sudden SNHL were evaluated; 13 (3.83%) had SAD.
- Three patients had bilateral involvement (16 ears total).
- Clinical, epidemiological, and audiological data were analyzed.
Conclusions:
- SAD prevalence is significant in sudden SNHL patients.
- Most SAD-associated SNHL cases presented with tinnitus, dizziness, unilateral, and profound hearing loss.
- These patients exhibited more severe initial impairment, higher bilateral involvement, poorer treatment response, and worse prognosis compared to SNHL of unknown etiology.

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:19Hypersensitivity Reactions: Immune-Complex Reactions
64
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum...
