Summary
Contact allergy is common in diabetes medical device (MD) users. Specific allergies, like Myroxylon pereirae resin, were more prevalent in individuals with diabetes.
Area of Science:
- Dermatology
- Allergology
- Endocrinology
Background:
- The prevalence of contact allergy among individuals with diabetes, particularly those using diabetes medical devices (MDs), remains largely unknown.
- Understanding these allergies is crucial for managing patient health and device compatibility.
Purpose of the Study:
- To determine the prevalence of contact allergy in users of diabetes medical devices.
- To compare allergy rates in individuals with diabetes to control groups.
Main Methods:
- Adults with type 1 diabetes underwent patch testing using the Swedish baseline series (SBS) and a specific MD series.
- Contact allergy rates to the SBS were compared with those of consecutive dermatitis patients.
Main Results:
- Contact allergy prevalence to the SBS was similar between individuals with diabetes (34.3%) and controls (39.6%).
- A higher prevalence of sesquiterpene lactone mix allergy (2.5% vs. 0.3%) and Myroxylon pereirae resin (MP) allergy (8.3% vs. 3.8%) was observed in individuals with diabetes compared to controls.
Conclusions:
- Contact allergy to the SBS is common in diabetes MD users.
- The overrepresentation of MP allergy in individuals with diabetes warrants further investigation to identify causative agents.

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...
01:30Allergic 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),...
01:12Type I Diabetes I: Introduction
Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
01:25Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
