Angry back syndrome is often due to marginal irritants: a study of 17 cases seen over 4 years.
17 patients with angry back syndrome were identified over a 4-year period (1994-97). 10 such patients were classified as multiple reactors and 7 as exacerbations of atopic eczema. The 10 multiple reactors reacted most commonly to medicaments, rubber chemicals, fragrances, methylchloroisothiazolinone/methylisothiazolinone, colophonium and nickel. A final diagnosis of relevant allergic contact dermatitis was made in 8 of the 10 patients with multiple reactions. Relevant contact allergens were rubber chemicals, plants, metals and preservatives, all of which can be marginal irritants. None of the reactions in the patients with exacerbation of dermatitis were thought to be relevant or helpful in the further management of the patient. Reactions in the angry back syndrome appear to be due most commonly to marginal irritants. In multiple reactors, marginal irritants were also the most common allergens finally identified.
