Sensitivity to ingested metabisulfite: variations in clinical presentation
The Journal of Allergy and Clinical Immunology
|May 1, 1983
Summary
Anaphylactic reactions linked to meals were diagnosed as sensitivity to metabisulfites. Allergy and immunologic studies confirmed this food allergy, highlighting the need for careful diagnosis.
Area of Science:
- Allergy and Immunology
- Clinical Medicine
Background:
- Anaphylaxis is a severe, potentially life-threatening allergic reaction.
- Reactions are often triggered by specific food allergens or environmental factors.
Observation:
- Two patients experienced anaphylactic episodes temporally associated with meal consumption.
- Initial clinical presentation suggested a food-related allergic response.
Findings:
- Comprehensive allergy and immunologic evaluations identified metabisulfite sensitivity as the cause.
- Metabisulfites, commonly used as preservatives, were confirmed as the specific triggers.
Implications:
- This case series underscores the importance of considering sulfite sensitivity in unexplained anaphylaxis.
- Accurate diagnosis of metabisulfite allergy is crucial for effective patient management and avoidance strategies.

01:26Toxic Reactions: Overview
4.2K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

01:22Phase II Reactions: Glutathione Conjugation and Mercapturic Acid Formation
1.3K
Glutathione, a tripeptide made up of glutamate, cysteine, and glycine, is a critical player in the detoxification of drugs and xenobiotics via a process known as glutathione conjugation or mercapturic acid formation. This phase II biotransformation reaction involves the covalent binding of glutathione to a drug or its metabolite, enhancing the compound's water solubility and enabling its excretion.
Several distinctive characteristics distinguish glutathione conjugation from other phase II...

Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...

01:16Drug toxicity: Idiosyncratic Reactions
220
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...

2.9K
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

01:20Sulfur Assimilation
554
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to...
