At the Department of Allergy and Clinical Immunology of Bach Mai Hospital in 1981-2003 year period, 1.728 patients with drug allergy and a controll group including 143 healthy students without allergic history were enrolled into study. Almost drug had been used in consultative clinic could make allergic reaction. 128 type of medicines could make diverse allergic reactions on 1.728 patients. Among 27 groups of medicine, antibiotics were the main caused with 72.4%. The main clinical symptoms of drug allergy in 615 inpatients were itchi, fever, dizzi, uncomfortable feeling and urticaria and some dangerous symdroms as Stevens-Johnson and Lyell syndrome.

Food allergy is defined as abnormal immune response elicited by food intake, in which a variety of clinical symptoms will appear as a result of physiological dysfunction and/or tissue damage. Possible mechanisms for food allergy include gastrointestinal tract barrier damage, failure to induce oral immune tolerance, intrauterine sensitization, and allergen transmission during pregnancy and breastfeeding. Hereditary and environmental factors can also contribute to the disease. Gastrointestinal disorders are the main clinical manifestations of the disease. However, hypoalbuminemia, growth retardation, and even acute circulatory failure or shock may occur in severe cases. Oral food challenges are the "gold standard" for the diagnosis of food allergy. Avoidance and replacement of the responsible food are the only effective treatment options for neonatal food allergy. The use of probiotics can offer protection against the disease.

Gastroesophageal reflux (GER) and cow's milk allergy (CMA) are common disorders in infants. In recent years, more and more research has investigated the relationship between these two diseases. Some studies reported that about half of the cases of GER in infants younger than 1 year may be an association with CMA. Therefore, overall understanding the role of CMA on the pathogenesis of GER has a great importance on improving clinical level of diagnosis and therapy. This review article tried to elaborate advances in research on the relationship between CMA and GER in infants, including epidemiology, pathogenesis, clinical manifestations, diagnosis and treatment.

Allergic reactions caused by traditional Chinese medicine injections (TCMIs) become a greatest concern in the clinic application safety. The integral animal evaluation method commonly used in the preclinical evaluation for allergic reactions of TCMIs was not sensitive, specific, quick and objective in observation indexes. Therefore, more researchers have paid attention to the in vitro test method for evaluating allergic reactions induced by TCMIs. Currently, the methods for evaluating allergic reactions induced by TCMIs are mainly targeted at type I allergic reaction and anaphylactic reaction, with only a few in vitro methods for evaluating type II allergic reaction. In this paper, researchers summarized relevant literatures published about evaluation methods for allergic reactions induced by TCMIs in recent years.

Because of the rapid action and high bioavailability, traditional Chinese medicine injections (TCMIs) had been widely used in clinical critical field. In recent years, with the increasing reports of clinical adverse reaction, more and more attention was paid to them, and acute allergic reaction was the main adverse reaction. Acute allergic reaction included type-I anaphylaxis reaction and anaphylactoid reaction, the latter had been found in a variety of TCMIs and accounted for 77% of adverse reaction. But the mechanism of anaphylactoid reaction was not completely understood, the standard animal model for TCMIs was not established, and the technical guidance for anaphylactoid reaction was not formulated. Thus the three aspects included mechanism, evaluation index and evaluation methods of TCMIs for anaphylactoid were reviewed. Five ways including direct stimulating pathway, complement pathway, coagulation pathway, kallikrein-kinin pathway and acute allergic pathway were the main mechanism of anaphylactoid reaction; whole animal model and cell model were the main evaluation methods; the occurrence index and effect index were reviewed for the evaluation index analysis.

Food-dependent, exercise-induced anaphylaxis (FDEIA) is a potentially life-threatening disorder that often occurs with exercise, and patients typically have eaten a specific food within hours before disease onset. This disease is exceedingly rare, with a prevalence of 0.02%. No well-recognized prevention or treatment strategy has been available for FDEIA except avoiding triggers strictly. Here we report an 11-year-old boy with a history of recurrent anaphylaxis of unknown etiology more than 10 times within two years. As the anaphylactic symptoms had not been controlled after traditional treatments, the patient was given subcutaneous injection of dupilumab seven times within 33 weeks. During dupilumab treatments, the patient was exposed to culprit mushrooms plus exercises at least twice a month but without notable anaphylaxis. Thus, Dupilumab may improve the allergic reactions in FDEIA patients.

Anaphylaxis following laminaria insertion rarely occurs but may be a life-threatening condition. Laminaria tents, prepared from natural sea kelp, are commonly used prior to elective termination of pregnancy to achieve cervical dilatation. We report herein two cases of anaphylaxis caused by IgE-mediated hypersensitivity to laminaria. Two women, each of whom had undergone at least one previous abortion where a laminaria had been utilized, developed anaphylactic reaction following laminaria insertion. The reaction included urticaria, nausea, breathing difficulty, and hypotension. The patients subsequently underwent skin testing and measurement of serum specific IgE level to laminaria extract, and were shown to elicit positive responses to laminaria. The implication and impact of laminaria allergy on gynecologic procedures are significant and this allergy should be included in the list of differential diagnoses for hypersensitive reaction in gynecologic procedures.

Drug hypersensitivity syndrome to both vancomycin and teicoplanin has not been previously reported. We describe here a 50-yr-old male patient with vertebral osteomyelitis and epidural abscess who developed hypersensitivity syndrome to both vancomycin and teicoplanin. Skin rash, fever, eosinophilia, interstitial pneumonitis, and interstitial nephritis developed following the administration of each drug, and resolved after withdrawing the drugs and treating with high dose corticosteroids. The vertebral osteomyelitis was successfully treated with 6-week course of linezolid without further complications. Skin patch tests for vancomycin and teicoplanin was done 2 months after the recovery; a weak positive result for vancomycin (10% aq.,+at D2 and +at D4 with erythema and vesicles; ICDRG scale), and a doubtful result for teicoplanin (4% aq.-at D2 and+/-at D4 with macular erythema; ICDRG scale). We present this case to alert clinicians to the hypersensitivity syndrome that can result from vancomycin and teicoplanin, with possible cross-reactivity, which could potentially be life-threatening.
