Idiopathic non-histaminergic angio-oedema after routine extubation successfully treated with fresh frozen plasma.

Non-allergic angio-oedema is a potentially life-threatening condition typically seen in patients with hereditary or acquired angio-oedema caused by C1 inhibitor deficiency or an adverse drug reaction to angiotensin converting enzyme inhibitors. We report a case of sudden angio-oedema in a patient who developed severe swelling of the tongue and neck after routine extubation requiring resuscitative re-intubation. The oedema was refractory to conventional allergy treatment. Shortly thereafter, the patient was treated with fresh frozen plasma, and within a few hours his condition improved, allowing extubation. Familial history and exposure to potentially angio-oedema causative drugs were not evident. The serum complement status was normal, and no IgE sensitisation was detected. We therefore concluded that the patient was suffering from idiopathic non-histaminergic angio-oedema. To our knowledge, this is the first reported case of an acute, life-threatening attack of idiopathic non-histaminergic angio-oedema that was successfully treated with fresh frozen plasma.

Antimicrobial silk clothing in the treatment of atopic dermatitis proves comparable to topical corticosteroid treatment.

BACKGROUND: Atopic dermatitis (AD) is aggravated by mechanical irritation and bacterial colonization. OBJECTIVE: This study compared the efficacy of an antimicrobial silk fabric (DermaSilk) with that of a topical corticosteroid in the treatment of AD. METHODS: Fifteen children were enrolled and wore a dress, where the left side was made of DermaSilk and the right side was made of cotton. The right arm and leg were treated daily with the corticosteroid mometasone for 7 days. The treatment efficacy was measured with a modified EASI (Eczema Area and Severity Index) and with an assessment by the patients/parents and by a physician. All patients were evaluated at baseline, as well as 7 and 21 days after the initial examination. RESULTS: All parameters showed that, irrespective of the treatment, there was a significant decrease of eczema after 7 days. No significant difference between DermaSilk-treated and corticosteroid-treated skin could be observed. CONCLUSION: DermaSilk showed potential to become an effective treatment of AD.

House dust allergy: correlation between in vivo and in vitro diagnostic tests.

Two different house dust preparations (house dust and fractionated house dust) were compared using intracutaneous skin tests and RAST assays in 91 patients suspected of house duct sensitivity. Total correlations of 54-64% (house dust) and of 68-74% (fractionated house dust) were obtained. The positive/positive correlations amounted to 52% (n = 66) and to 60% (n = 42) respectively. Seventeen patients were also tested by nasal provocation (NPT) and 33 by bronchial provocation (BPT) using the same house dust extract. Correlations between NPT and skin tests and NPT and RAST were 42% and 47% respectively and between BPT and skin tests and BPT and RAST 56% and 57% respectively.

Clinical trial of Ro 6-0787, a monovalent specific hapten inhibitor of penicillin allergy.

A second clinical trial of the compound Ro 6-0787, which is a specific monovalent penicilloyl hapten inhibitor of allergic reactions to penicillin has been conducted by investigators from 9 different European groups in 90 patients allergic to penicillin. The effect of a combined Ro 6-0787-penicillin therapy was considered as clinically successful in the large majority of cases, since treatment with penicillin could be pursued or resumed without allergic manifestation in 42 from 46 cases (91 percent). The effect of Ro 6-0787 alone on acute allergic manifestations after interruption of penicillin therapy was more difficult to evaluate but was nevertheless considered satisfactory in 17 from 26 patients (65 percent). A depression of skin hypersensitivity to PPL and/or penicillin and penicillin derivatives sometimes persisting for weeks and months was obvious in numerous allergic patients submitted to combined Ro 6-0787-penicillin treatment. A depressing effect on antipenicillin antibody titers detected by passive hemaglutination was also manifest in some patients. Failure to suppress allergic manifestations was reported in 11 cases, among which some may have been due to insufficient dosage of inhibiting hapten. The overall tolerance of Ro 6-0787 in allergic patients has been very good. Nevertheless, the major obstacle to a wider general use of Ro 6-0787 at the present time appears to be the occurrence of positive skin reactions to that compound in approximately 5 percent of patients allergic to penicillin. It is not yet ascertained whether the occasional positive skin reactions and urticaria to Ro 6-0787 may have been due to aggregation, or incomplete dissolution of the compound or whether it reflects hypersensitivity to another antigenic determinant. With the reservation that patients with positive skin test to Ro 6-0787 have for the time being to be excluded from combined treatment, this monovalent hapten certainly offers a new possibility to resume and/or pursue penicillin therapy in patients demonstrably allergic to that drug.
