Churg Strauss syndrome: a review
Summary
Churg Strauss syndrome, a condition involving asthma, eosinophilia, and vasculitis, has an improved prognosis with steroid and immunosuppressive therapies. Early diagnosis based on history, examination, and specific criteria is crucial for effective management.
Area of Science:
- Rheumatology
- Pulmonology
- Immunology
Background:
- Churg Strauss syndrome is an idiopathic condition characterized by asthma, eosinophilia, and small vessel vasculitis affecting the lungs and nasal sinuses.
- The syndrome's natural history, pathogenesis, clinical manifestations, and treatment options are not fully understood.
Purpose of the Study:
- To review the natural history of Churg Strauss syndrome.
- To highlight the pathogenesis, clinical features, and available treatment modalities.
- To discuss the prognosis of patients diagnosed with this condition.
Main Methods:
- A comprehensive literature review was conducted.
- Searches included manual library searches, journal articles, internet resources, and conference abstracts.
Main Results:
- Churg Strauss syndrome predominantly affects middle-aged individuals, with a history of new or worsening asthma.
- The condition exhibits a male predisposition.
- While previously fatal, steroid and immunosuppressive therapies, such as prednisolone, have significantly improved patient outlook and long-term survival.
Conclusions:
- Suspicion of Churg Strauss syndrome requires thorough patient history, physical examination, and laboratory investigations.
- Diagnosis should be confirmed using the established criteria set forth by the American College of Rheumatology.

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
01:30Esophageal Strictures-I: Introduction
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

01:26Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

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...
01:20COPD: Pathogenesis and Clinical Features
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

01:21Barrett Esophagus-II: Clinical Manifestations and Management
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...
