Summary
Sulphite additives in foods and pharmaceuticals can cause adverse reactions, including skin issues and asthma attacks, in sensitive individuals. Awareness and dietary changes can significantly improve outcomes for those affected by sulphite sensitivity.
Area of Science:
- Food science and toxicology
- Clinical immunology
- Dermatology and pulmonology
Background:
- Sulphites are common food and pharmaceutical additives used as preservatives and antioxidants.
- Exposure to sulphites, via ingestion, topical application, or parenteral routes, can trigger diverse adverse clinical effects in sensitive individuals.
- These reactions range from mild skin conditions like dermatitis and urticaria to severe respiratory distress and anaphylaxis.
Purpose of the Study:
- To review the clinical manifestations and sources of sulphite sensitivity.
- To highlight the prevalence and risk factors associated with sulphite-induced reactions, particularly in asthmatic populations.
- To underscore the importance of physician awareness regarding sulphite sensitivity.
Main Methods:
- Literature review of studies on sulphite sensitivity.
- Analysis of reported adverse clinical effects and exposure routes.
- Examination of prevalence data, especially in asthmatic subjects.
Main Results:
- Sulphite sensitivity presents with a spectrum of symptoms, including skin reactions and respiratory issues.
- Asthmatic individuals, particularly those with steroid dependence or high airway hyperresponsiveness, face increased risk.
- Prevalence of sulphite sensitivity in asthmatics ranges from 3-10% following ingestion.
Conclusions:
- Sulphite sensitivity can manifest in acute, chronic, skin, and respiratory symptoms.
- Physicians need to recognize the varied clinical presentations and sources of sulphite exposure.
- Dietary and behavioral modifications are effective in managing sulphite sensitivity.

01:20Sulfur Assimilation
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 become...
01:26Toxic Reactions: Overview
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,...

01:27Effects of Chemicals: Overview
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...
01:21Skeletal Muscle Relaxants: Adverse Effects
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.

01:36Types of Toxins
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
