GC is wonderful drug to prevent and control bronchial asthma. Methods: 1026 inpatients with asthma presented at the Department of Allergy and Clinical Immunology were included in this study. Cross - sectional surveys and retrospective studies. Objectives: Study on situation of using GC of asthmatic patients. Describe adverse drug reactions of glucocorticoid to asthmatic in - patients at the Department of Allergy and Clinical Immunology. Results: All of 1026 patients used Gc. Prednisolon, solu - medrol, depersolon and pulmicort were most used medications. There were 295 asthmatic patients have side effects (28.75%) with 24 types of symptom, 15 diseases and syndromes are resulted: Cushing syndrome, gastric ulcer, diabetes, hypertension, ponosis, retarded development... Almost systemic organs of the patients were influenced negatively by Gc. It has relationship among the way to use, the time in used GC and adverse drug reactions of GC. Conclusions: GC caused many adverse drug reactions to asthmatic patients.

Study on 98 patients with SJS and Lyell were treated at the Department of Allergology and Clinical immunology in Bach Mai Hospital (1997-2002). SJS & TEN always occurred when patients used the ampicillin and antibiotics of beta-lactam family, carbamazepine and anti-convulsion drugs properly or not.

Tuberculosis treatment-related allergic reactions are increasing. It influenced to therapy regimen for tubeculosis over our country. Objectives: (1) Make a list of tuberculosis treatments can cause allergic reactions. (2) Study on clinical symptoms of tuberculosis treatment allergy in tubeculosis patients. (3) Study on some of liver biochemical test. Subjects and method: 91 patients who had allergic reactions related to tuberculosis treatments presented between 1998 and 2003 in the National Hospital of Tubeculosis and Lung Diseases. Cross sectional survey and retrospective study. Results: There are 6 tuberculosis treatments related to allergic reactions: rifampicin, streptomycin, ethambutol, isoniazid, pyrazynamid and RH; Rifampicin, streptomycin and ethambutol are main cause. Most of all allergic reations happened late (after 24 hours) in patients with lung tuberculosis treated by "formula I".

At the Department of Allergy and Clinical immunology of Bach Mai Hospital from the year 1981 – 2003, study was performed in vivo on 1.728 patients of drug allergy and a control group of 143 healthy students without allergic history. Results showed that the positive rate of mastocyte degenerative reaction was 81.2%, of the test of lymphocyte transformation was 76.2%, applicated skin test was 66.7%. The highly accurate test such as the total IgE quantification and the determination of the number of thrombocyte in the forth of T lymphocyte were recommended for complementing, the diagnosis and for minotring the treatment of drug allergy. Methyl-prednisolon, Dimedron, vitamin C and glucose solution were the main medication for allergic control. Patients with Stevens-Johnson and Lyell syndromes required special cares such as for burn, preliminary good results were given for 100% of patients. Mean duration of the course of treatment got 9.6 6.8 days and for Stevens-Johnson syndrome 16.1  9.5 days.
