Satisfaction, Qol and adherence of patients allergic to dust mites and/or pollens undergoing sublingual immunotherapy.

Aim: Sublingual immunotherapy (SLIT) changes history of allergic respiratory disease (ARD). However, adherence is a barrier for optimal outcomes. Patients & methods: In the QUALI study, 859 patients with house-dust mite (HDM) and/or pollen induced ARD uncontrolled with symptomatic treatment and undergoing SLIT for at least 6 months or including one pre-coseason (pollen) were collected. Results & conclusion: SLIT significantly improved allergic rhinoconjunctivitis (ARC) and asthma symptom control, leading to reduced medication, meaningful health-related quality of life gain, improved nasal, ocular and bronchial symptoms and everyday life activities. Patients were highly satisfied and most of them adhered to SLIT, being forgetfulness the main non-adherence motive. SLIT is a quick effective treatment against persistent moderate-to-severe symptoms in ARC and asthma but it should been improve forgetfulness, as non-adherence reason.

Sublingual immunotherapy (SLIT) has really changed how we deal with allergic respiratory disease. But there's a catch: sticking to the treatment can be tough.In the QUALI study, we looked at 859 patients dealing with dust mite and/or pollen allergies who were not getting relief from the usual treatments. We put them on SLIT for at least 6 months or during pollen season.This treatment made a big difference. Symptoms got better, people needed less medication and they felt better in their day-to-day lives. Most patients were happy with the treatment and stuck to it well, but some forgot sometimes.In short, SLIT works fast and works well for moderate to severe allergies and asthma. But we need to help people remember to stick with it.

Evaluating the usefulness of retesting for beta-lactam allergy in children.

Many children with adverse reactions to beta-lactams are labeled as allergic without performing an allergy study to confirm it. In this retrospective study of 10 years, we detected only 3.3% positive cases. Although international guidelines recommend a second allergy workup in patients with a negative study, we found from our results a low profitability of retesting.

T cell activity in successful treatment of chronic urticaria with omalizumab.

Omalizumab, a humanized monoclonal anti-IgE antibody has the potential to alter allergen processing. Recently, it has been postulated the assessment of PHA-stimulated adenosine triphosphate (ATP) activity as maker of CD4+ T cells activity in peripheral blood cells. We present the case report of a 35-year-old woman with a history of chronic idiopathic urticaria and angioedema of 8 years of development with poor response to treatment. The patient was partially controlled with cyclosporine at doses of 100 mg/12 h. However, she was still developing hives daily. Finally treatment with omalizumab was started at dose of 300 mg every 2 weeks. The patient experienced a decrease in urticarial lesions 2 days after starting therapy. We also evaluated the effects of omalizumab therapy on the activity of peripheral blood CD4+ T cells from the patient, in order to determine the potential modification of anti-IgE therapy on the process of antigen presentation-recognition. Activity of CD4+ cells by ATP release was clearly increased demonstrating an enlarged CD4 activity. Omalizumab may be useful in the treatment of severe chronic urticaria. ATP activity of peripheral blood CD4+ T cells might be a non-subjective method to assess Omalizumab activity.

Oral mite anaphylaxis by Thyreophagus entomophagus in a child: a case report.

Sensitization to Thyreophagus entomophagus, a storage mite, is uncommon and might produce occupational respiratory disorders in farmers. We present the first case of a child suffering anaphylaxis produced by ingestion of contaminated flour with Thyreophagus entomophagus.
