Summary
Nitrofurazone and neomycin are common causes of allergic contact dermatitis. Patch testing revealed significant hypersensitivity reactions to these and other antibacterial agents in patients with suspected contact dermatitis.
Area of Science:
- Dermatology
- Allergology
- Pharmacology
Background:
- Contact dermatitis is a common skin reaction.
- Antibacterial agents are frequently implicated in allergic contact dermatitis.
- Understanding the incidence of hypersensitivity is crucial for patient management.
Purpose of the Study:
- To determine the incidence of contact hypersensitivity to various antibacterial agents.
- To identify specific antibacterial agents causing allergic contact dermatitis in a patient cohort.
Main Methods:
- Patch testing was conducted on 101 patients with suspected antibacterial-induced contact dermatitis.
- Standardized concentrations of nitrofurazone, neomycin, penicillin, and other agents were used.
- Reactions were assessed, and different formulations of neomycin and nitrofurazone were compared.
Main Results:
- Nitrofurazone (56 cases) and neomycin (28 cases) showed the highest rates of positive patch tests.
- Penicillin, tyrothricin, gentamicin, framycetin, and oxytetracycline also induced hypersensitivity.
- Higher concentrations of neomycin in petrolatum yielded more positive results than commercial preparations.
Conclusions:
- Nitrofurazone and neomycin are significant causes of allergic contact dermatitis.
- Multiple antibacterial agents can elicit hypersensitivity reactions.
- Patch testing is essential for diagnosing antibacterial-induced contact dermatitis.

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...

01:12Local Anesthetics: Adverse Effects
919
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...

01:30Hypersensitivities
8.0K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

01:19Hypersensitivity Reactions: Immune-Complex Reactions
73
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...

01:27Allergic Drug Reactions
1.5K
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...
