| Eosinophils in Parasitic Infections and Allergic Reactions Eosinophils are active in parasitic infections and in allergic reactions such as asthma and hay fever, and may be present in great numbers in the peripheral blood during these conditions.Stress, shock, or burns may also cause an increase in this type of cell.Eosinophils modulate an allergic response by liberating substances which can neutralize mast cell and basophil products. | View Page |
| TDM for Theophylline Theophylline is used as a bronchodilator for treatment of moderate to severe asthma and chronic obstructive pulmonary disease (COPD). TDM is needed for theophylline because the kinetics of the drug are highly variable. It has a narrow therapeutic window, and overdose can result in elevated heart rate, arrhythmia, and CNS excitability. Clearance of the drug is increased in children, smokers, persons with cystic fibrosis, and persons with hyperthyroidism. Elimination is slowed in congestive heart failure and in the elderly. | View Page |

| Eosinophilia Follow-Up As mentioned on the previous page, high percentages of eosinophils may be present in the peripheral blood smears of patients with a variety of conditions--asthma, urticaria, Loeffler's syndrome, larval parasitic infections and in chronic eosinophilic leukemia. One exception to the association of eosinophilia with parasitic infections is a fatal case of disseminated strongyloidiasis reported many years ago by Miale (Hematology--5th Edition, Mosby, pg. 776, 1977) in which the peripheral blood eosinophilia was masked by the administration of corticosteroids. | View Page |
