Environmental and occupational respiratory diseases – 1039. Clinical course and side effects of anti-IgE monoclonal antibody in patients with severe persistent asthma
Bibliographic record
Abstract
This article was originally published online on 23 April 2013 Omalizumab, a recombinant humanized monoclonal antibody to IgE, is recommended as a new option for the treatment of severe persistent allergic asthma. The purpose of this study is to assess the effects omalizumab treatment on life quality and its side effects in the severe persistent asthma patients. In this study, we evaluated 19 severe persistent asthma patients who received therapy with omalizumab for 8 months. Omalizumab was administered every 2 weeks between the doses of 150 to 375 mg. Symptoms and severity of allergic reactions were recorded before and after being on omalizumab. IgE levels, mean platelet volume (MPV), platelet levels, pulmonary function test and asthma control test were evaluated in all patients before and 8 months after the treatment. Local and systemic side effects of omalizumab were evaluated. Stool parasites were examined at 4th and 8th months after initiation of treatment to investigate any parasitosis. The patients had severe persistent asthma for periods ranging from 3 to 8 years, and they were diagnosed with allergic asthma for 7-28 years. Thrombocytopenia developed in a male patient after the 22nd dose of the drug was given. When the platelet count fell down to 55.000, the omalizumab treatment was suspended. During the therapy period, one patient had parasitosis (giardiasis), one patient had severe side effects, one patient had dyspnea two hours after the injection, and one patient had a dyspnea attack 2 hours after the injection. The changes in MPV levels were not statistically significant. There was also significant decrease in IgE levels after the treatment. Our clinical follow-up study suggesting that monitoring the complete blood cell count might be important in the use of omalizumab. Only in one case, a dyspnea attack occurred 2 hours after the injection. The patient was hospitalized and treated appropriately, and discharged after a 24 hours of follow-up period. Thrombocytopenia developed in one patient and the treatment was suspended. Although we did not have any anaphylaxis, we believe that the patients should be monitored at least for 3 hours after the Omalizumab injection.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
