Pyridoxine induced rosacea-like dermatitis
Acta Clinica Croatica
|June 11, 2015
Summary
Rosacea is an inflammatory skin condition. A case study shows isoniazid and pyridoxine combination therapy for tuberculosis can induce rosacea-like symptoms.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Rosacea is a common chronic inflammatory skin disease affecting adults, characterized by facial redness and visible blood vessels.
- Its exact cause is unknown, but risk factors include genetics, skin type, sun exposure, and diet.
- Emerging evidence suggests certain medications and vitamins may trigger or worsen rosacea.
Observation:
- A 53-year-old female patient developed a rosacea-like skin condition.
- This occurred while she was undergoing treatment for pulmonary tuberculosis.
Findings:
- The patient was receiving a fixed combination of isoniazid and pyridoxine, along with rifampicin.
- The rosacea-like dermatitis was attributed to this specific drug combination.
Implications:
- This case highlights a potential drug-induced cause for rosacea-like symptoms.
- It emphasizes the importance of considering medication side effects in dermatological diagnoses.
- Further research is needed to understand drug-induced rosacea and its management.

01:30Vitamins
3.1K
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

01:30Drug Toxicity: Allergic Reactions
169
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...

01:16Drug toxicity: Idiosyncratic Reactions
195
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...

01:23Role of Skin in Vitamin D Synthesis
8.9K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

01:27Allergic Drug Reactions
1.6K
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...
