62 patients with tuberculosis experienced the antituberculosis drug allergy transferred to B¹ch Mai hospital in 1997. The reaction of mastocyte catalysis was used to identify the drug allergy. The results have shown that the rate of side effects of streptomycin, rifampicine, ethambutole, RH, PZH, PZA and INH was 73.91%, 64.7%, 63.88%, 59.09%, 40.74% and 16.66%, respectively. The common clinical symptoms were urticaria, itching, rash, and edema in face.

The study involved two groups: case group involved 65 patients with beta-lactam antibiotic allergy who were treating at B¹ch Mai Hospital during year 2000 and 25 healthy people were used a control group. Main findings: allergic symptoms onset rapidly within first 30 minutes in 43.07% of patients, onset after 1 hour of drug administration in 16.92% and after 1 day in 9.22%. 52.3% of patients have individual history and 13.84% have family history of allergy. Whole-body erythema occurred on 48.07% of patients, urticaria and Quinck edema on 27.69%, Stevens-Johnson syndrome on 18.46%, anaphylactic shock on 61.5% and drug-caused hepatitis on 4.61%. Levels of liver enzymes AST and ALT increase significantly in comparison with control group.

An investigation was carried out on 927 workers. A high rate of allergic disease was reported, especially at the respiratory system. 11 to 12 year long occupational ages are the most vulnerable ages with a highest rate of positive reaction to cotton dusty allergen. Mean value of pulmonary air flow volume decreased among all age groups in comparing with normal value.

908 people with allergy in which bronchial asthma: 113 and 997 medical students of Ha Noi medical University and pupils without history of allergy or without allergic diseases. Method: the finding of the sensitivity for foreign body (house dust) by prick tests as method of Dreborg. The results: the rate of sensitivity for foreign body (house dust) in the normal people, people with allergy and people with bronchial asthma were a statistical significance: 13.14; 35.13 and 57.14, respectively.

A study on 201 persons with the allergy within 2852 persons in Dong da, Hai ba trung, Ba dinh, Thanh tri, Tu liem districts, Ha noi has shown that 66.66% persons with the drug allergy had history of his own allergy or his family allergy. The allergy in the history comprises drug allergy, urticaria, allergic rhinitis, bronchial asthma, food allergy, chemical allergy.. The risk of allergy of persons with allergic history is higher 4 times than this of the normal person.

The study involved 197 patients at Clinical Immunology - Allergy Department of Bach Mai Hospital. These patients were diagnosed with asthma based on diagnostic criteria of the American Thoracic Association. Method: Clinical examination. Time of disease onset and factors that related to the arise of first breath difficulty. Date was processed by statistic method. The results showed that asthma could arise at any age. The prevalence is highest (39.59%) in children and teens (0-20 years of old) and lowest (4.06%) in group of 60 years of old or more. Among causal factors of asthma, respiratory inflammations such as bronchitis, pneumonia, tonsillitis and allergic rhinitis were most common (67.5%).
