          Abstract

          Antibiotics are used extensively in the treatment of various infections. Consequently, they can be considered among the most important agents involved in adverse reactions to drugs, including both allergic and non-allergic drug hypersensitivity [J Allergy Clin Immunol 113:832–836, 2004]. Most studies published to date deal mainly with reactions to the beta-lactam group, and information on hypersensitivity to each of the other antimicrobial agents is scarce. The present document has been produced by the Special Committee on Drug Allergy of the World Allergy Organization to present the most relevant information on the incidence, clinical manifestations, diagnosis, possible mechanisms, and management of hypersensitivity reactions to non beta-lactam antimicrobials for use by practitioners worldwide.

            The lymphocyte transformation test in the diagnosis of drug hypersensitivity.

            Diagnosis of drug hypersensitivity is difficult, as an enormous amount of different drugs can elicit various immune-mediated diseases with distinct pathomechanism. The lymphocyte transformation test (LTT) measures the proliferation of T cells to a drug in vitro--from which one concludes to a previous in vivo reaction due to a sensitization. This concept of the LTT has been confirmed by the generation of drug-specific T-cell clones and the finding that drugs can directly interact with the T-cell receptor, without previous metabolism or need to bind to proteins. In this review, technical aspects and usefulness of this test for the diagnosis of drug hypersensitivity are discussed. The main advantage of this test is its applicability with many different drugs in different immune reactions, as drug-specific T cell are almost always involved in drug hypersensitivity reactions. Its main disadvantages are that an in vitro proliferation of T cells to a drug is difficult to transfer to the clinical situation and that the test per se is rather cumbersome and technically demanding. In addition, its sensitivity is limited (for beta-lactam allergy it is in the range of 60-70%), - although at least in our hands - it is higher than of other tests for drug hypersensitivity diagnosis. Consequently, drug hypersensitivity diagnosis needs to rely on a combination of history and different tests, as none of the single tests available has per se a sufficiently good sensitivity. Within this setting, the LTT has proven to be a useful test for the diagnosis of drug hypersensitivity reactions and helped to better understand these reactions. Further work on the simplification of this test and systematic evaluation of its sensitivity and specificity in some main groups of drugs are necessary to make this test more widely available.

              Association of chronic nasal carriage of Staphylococcus aureus and higher relapse rates in Wegener granulomatosis.

              To examine possible risk factors for relapse, including chronic nasal carriage of Staphylococcus aureus and serial antineutrophil cytoplasmic antibody (ANCA) determinations in patients with Wegener granulomatosis. Observational cohort study. Outpatient clinic at a university-affiliated hospital. Consecutive patients (n = 71) with biopsy-proven Wegener granulomatosis who were seen during follow-up at the outpatient clinic from January 1988 to July 1991. Fourteen patients were ineligible or dropped out; 57 patients were analyzed. Serial ANCA determinations and swab cultures of both anterior nares for S. aureus taken at each visit every 4 to 6 weeks. Occurrence of infections and relapses of Wegener granulomatosis were identified according to strict, predefined criteria. Thirty-six of the 57 patients (63%; 95% CI, 49% to 76%) were found to be chronic nasal carriers of S. aureus (> or = 75% of nasal cultures positive for S. aureus). Proportional-hazards regression analysis identified chronic nasal carriage of S. aureus (adjusted relative risk, 7.16; CI, 1.63 to 31.50), creatinine clearance above 60 mL.min-1 (adjusted relative risk, 2.94; CI, 1.27 to 6.67), and a history of previous relapses of Wegener granulomatosis (adjusted relative risk, 1.33; CI, 0.98 to 1.78) as independent risk factors for relapse. Twenty-two of 33 patients persistently or intermittently positive for ANCA had a relapse as opposed to only 1 of 21 persistently negative patients. Relapses of Wegener granulomatosis were not related to diagnosed infections. Chronic nasal carriage of S. aureus identifies a subgroup of patients with Wegener granulomatosis who are more prone to relapses of the disease, suggesting a role for S. aureus in its pathophysiology and a possible clue for treatment.
