Summary
Hereditary angioedema is a genetic disorder affecting C1 esterase inhibitor. This case study details a 25-year-old male diagnosed with hereditary angioedema type 1, successfully treated with stanozolol.
Area of Science:
- Immunology
- Genetics
- Pharmacology
Background:
- Hereditary angioedema (HAE) is a rare genetic disorder.
- It results from C1 esterase inhibitor (C1-INH) deficiency or dysfunction.
- HAE causes recurrent swelling episodes, often mistaken for allergic reactions.
Purpose of the Study:
- To report a case of hereditary angioedema type 1.
- To highlight diagnostic findings and treatment outcomes.
- To differentiate HAE from allergic angioedema.
Main Methods:
- Clinical case presentation.
- Patient history and physical examination.
- Laboratory investigations including complement C4 and C1-INH levels.
- Treatment with stanozolol.
Main Results:
- A 25-year-old male presented with facial swelling.
- History of recurrent, self-subsiding swelling episodes.
- Diagnosed with HAE type 1 due to low C4 and C1-INH levels.
- Stanozolol treatment resulted in no recurrence over one year.
Conclusions:
- Hereditary angioedema type 1 is a distinct genetic condition.
- Timely diagnosis and appropriate treatment are crucial.
- Stanozolol can be effective in managing HAE type 1 symptoms.

01:30Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...

Overview
01:27Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
01:30Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
01:20Asthma: Pathogenesis and Management
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

01:30Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors
Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...
