Spondylarthritis presenting with an allergic immediate systemic reaction to adalimumab in a woman: a case report

<p>Abstract</p> <p>Introduction</p> <p>The efficacy of adalimumab, a fully human anti-tumor necrosis factor α recombinant antibody, has dramatically improved the quality of life of patients with rheumatoid and psoriatic arthritis and Crohn's disease. Because it is fully human, one should not expect immune reactions to this molecule. Adverse reactions to adalimumab are limited mainly to injection site reactions and are very common. Immediate systemic reactions are rarely reported.</p> <p>Case presentation</p> <p>We report the case of a 61-year-old Caucasian woman who was treated with adalimumab for spondylarthritis and developed injection site reactions after the sixth dose. After a two-month suspension, she recommenced therapy and experienced two systemic reactions. The first occurred after one hour with itching of the palms and soles and angioedema of the tongue and lips. Thirty minutes after the next dose the patient had itching of the palms and soles with diffusion to her whole body, angioedema of the lips, dizziness and visual disturbances. A skin-prick test and intra-dermal tests with adalimumab gave strong positive results at the immediate reading. However, serum-specific immunoglobulin E (IgE) to adalimumab were not detectable by using Phadia solid phase, especially harvested for this case, in collaboration with our Immunology and Allergy Laboratory Unit. Her total IgE concentration was 6.4 kU/L.</p> <p>Conclusion</p> <p>We describe what is, to the best of our knowledge, the first reported case of immediate systemic reaction to adalimumab studied with a skin test giving positive results and a serum-specific IgE assay giving negative results. The mechanism of the reaction must be immunologic but not IgE-mediated.</p

A survey of clinical features of allergic rhinitis in adults

Background: Allergic rhinitis (AR) has high prevalence and substantial socio-economic burden. Material/Methods: The study included 35 Italian Centers recruiting an overall number of 3383 adult patients with rhinitis (48% males, 52% females, mean age 29.1, range 18\u201345 years). For each patient, the attending physician had to fill in a standardized questionnaire, covering, in particular, some issues such as the ARIA classification of allergic rhinitis (AR), the results of skin prick test (SPT), the kind of treatment, the response to treatment, and the satisfaction with treatment. Results: Out of the 3383 patients with rhinitis, 2788 (82.4%) had AR: 311 (11.5%) had a mild intermittent, 229 (8.8%) a mild persistent, 636 (23.5%) a moderate-severe intermittent, and 1518 (56.1%) a moderate-severe persistent form. The most frequently used drugs were oral antihistamines (77.1%) and topical corticosteroids (60.8%). The response to treatment was judged as excellent in 12.2%, good in 41.3%, fair in 31.2%, poor in 14.5%, and very bad in 0.8% of subjects. The rate of treatment dissatisfaction was significantly higher in patients with moderate-to-severe AR than in patients with mild AR (p<0.0001). Indication to allergen immunotherapy (AIT) was significantly more frequent (p<0.01) in patients with severe AR than with mild AR. . Conclusions: These fndings confirm the appropriateness of ARIA guidelines in classifying the AR patients and the association of severe symptoms with unsuccessful drug treatment. The optimal targeting of patients to be treated with AIT needs to be reassessed

N-3 fatty acids in patients with multiple cardiovascular risk factors

BACKGROUND: Trials have shown a beneficial effect of n-3 polyunsaturated fatty acids in patients with a previous myocardial infarction or heart failure. We evaluated the potential benefit of such therapy in patients with multiple cardiovascular risk factors or atherosclerotic vascular disease who had not had a myocardial infarction. METHODS: In this double-blind, placebo-controlled clinical trial, we enrolled a cohort of patients who were followed by a network of 860 general practitioners in Italy. Eligible patients were men and women with multiple cardiovascular risk factors or atherosclerotic vascular disease but not myocardial infarction. Patients were randomly assigned to n-3 fatty acids (1 g daily) or placebo (olive oil). The initially specified primary end point was the cumulative rate of death, nonfatal myocardial infarction, and nonfatal stroke. At 1 year, after the event rate was found to be lower than anticipated, the primary end point was revised as time to death from cardiovascular causes or admission to the hospital for cardiovascular causes. RESULTS: Of the 12,513 patients enrolled, 6244 were randomly assigned to n-3 fatty acids and 6269 to placebo. With a median of 5 years of follow-up, the primary end point occurred in 1478 of 12,505 patients included in the analysis (11.8%), of whom 733 of 6239 (11.7%) had received n-3 fatty acids and 745 of 6266 (11.9%) had received placebo (adjusted hazard ratio with n-3 fatty acids, 0.97; 95% confidence interval, 0.88 to 1.08; P=0.58). The same null results were observed for all the secondary end points. CONCLUSIONS: In a large general-practice cohort of patients with multiple cardiovascular risk factors, daily treatment with n-3 fatty acids did not reduce cardiovascular mortality and morbidity.
