The definition of anaphylaxis is 'a serious, life-threatening generalized or systemic hypersensitivity reaction' and is considered as the life threatening adverse drug reaction. We experienced a case of cefotetan induced anaphylaxis with negative pre-skin test, used for surgical prophylaxis. A 82-year-old female was scheduled for total knee replacement therapy. She had no previous history of allergy and her skin test results were also negative. On her right knee surgery, she underwent cefotetan therapy as a surgical prophylaxis for a week with no problems identified. Next left knee surgery, she also received the prophylaxis of intravenous cefotetan. However, a few minutes later, anaphylactic reaction developed with vomiting, severe hypotension, bronchospasm, and dyspnea. After immediate intensive care treatment, she recovered without significant complications. Though commonly used laboratory data in case reports, such as the specific IgE, tryptase, histamine, or allergic skin prick test were limited, we successfully confirmed anaphylaxis based on clinical criteria for diagnosing anaphylaxis based on WAO 2011 guideline with through concurrent patient°Øs medical history review and the process of identifying the causes.

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are immune-complex-mediated hypersensitivity reactions that predominantly involve skin and mucous membranes. Despite the low incidence, both are considered medical emergencies as the mortality rate has been estimated at 30-50%. Although as many as half of cases are idiopathic, several drugs have been implicated as main cause of SJS/TEN. This review therefore aimed to identify drugs that were potentially associated with SJS/TEN and compare the relative risk of the medications. Method: A comprehensive search was performed using MEDLINE, EMBASE and 5 Korean databases. We defined study drugs as non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics, antiepileptics, and allopurinol. Only epidemiologic studies investigating associations between the above drugs and drug-induced SJS/TEN were included. Two reviewers independently selected and evaluated candidate papers and extracted odds ratios or incidence rates. Meta-analysis was performed only for drugs that were reported from 4 or more studies. Results: We found 8 case-control studies, 3 cohort studies and 1 RCT. The ranges of adjusted ORs were 0.6-34.0 for NSAIDs, 1.6-302.0 for antiepileptics, 0.3-10.0 for antibiotics and 1.0-187.0 for allopurinol. The drug with the highest incidence of SJS/TEN was carbamazepine (40 persons/1,000 DDD). Conclusion: Finally, the risk was highest in first 8 weeks after onset of treatment in all drugs.

Effects of methanol extract of Astragali Radix (AR) on the immune responses were studied using ICR mice. Mice were divided into 4 groups (10mice/group), and methanol extracts of AR at doses of 0.05, 0.25 and 1.25g/kg were orally administered to ICR mice once a day for 2 weeks. Mice were immunized and challenged with sheep red blood cells (SRBC). The results of this study were summarized as follows; (1) Methanol extract of AR at 0.05, 0.25 and 1.25g/kg didn't affect the weight ratios of thymus to body, as compared with those in controls, but significantly increased spleen weight ratio. (2)Methanol extract of AR at 0.05 and 0.25g/kg significantly increased hemagglutination titer and splenic plaque forming cells corresponding to humoral immunity, as compared with those in controls, but their enhancements were somewhat lowered at a high dose (1.25g/kg). (3) Methanol extract of AR at 0.05 and 0.25g/kg siginificantly increased delayed-type hypersensitivity reaction resulted from cell-mediated immunity, as compared with those in controls, but not so significant increases were observed at a high dose (1.25g/kg). (4) Methanol extract of AR at 0.05 and 0.25g/kg significantly increased phagocytic activity and the number of circulating leukocyte compared with those in controls, but their enhancements were lowered at a high dose (1.25g/kg). These results suggest that methanol extract of Astragali Radix increased humoral and cell-mediated immune responses, phagocytic activity and the number of circulating leukocyte, dependent upon dose, but inhibited their enhancement effects were decreased at a high dose (1.25g/kg).

Objective: To evaluate the current status of managing adverse reactions to iodinated contrast media (ICM) for computed tomography in referral hospitals in South Korea compared with hospitals in other countries. Materials and Methods: This survey investigation involved 59 Korean and 15 overseas hospitals using guideline-based questionnaires consisting of 24 items in 7 main categories related to managing adverse reactions to ICM. Results: Informed written consent with risk factor evaluation was appropriately performed in most of the Korean hospitals. There was considerable variability in assessing renal function across the hospitals; serum creatinine level was used as a reference in 76.4% of Korean hospitals. The Korean hospitals preferred a more stringent approach to determining normal renal function (p = 0.01), withholding metformin (p = 0.01), and fasting before ICM exposure (p < 0.001) compared with overseas hospitals. All the Korean hospitals had an emergency protocol and in-hospital system for adverse reactions to ICM. The Korean (87.7%) and overseas hospitals (100%) were similarly equipped with epinephrine (p = 0.332), but only 38.6% of Korean hospitals were equipped with a bronchodilator (p = 0.004). For patients with a previous hypersensitivity reaction to ICM, 62.3% of Korean hospitals pre-medicated with anti-histamine and corticosteroid according to the severity of the previous reaction, and changed the culprit ICM in 52.8%, while skin test was performed in 17%. Conclusion: In general, Korean referral hospitals were well-prepared regarding informed consent, protocol, and an in-hospital system for managing adverse reactions to ICM. Nevertheless, there was considerable variability in details and management, thus requiring standardization by reflecting current guidelines.

This review summarizes gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions. Gender differences in pharmacokinetics are categorized by four major factors: absorption/bioavailability, distribution, metabolism, and elimination. There are sex-based differences in gastric emptying time, gastric alcohol dehydrogenase activity, apparent volume of distribution, ${\alpha}1$-acid glycoprotein level, phase I (CYP) and phase II metabolizing enzymes, glomerular filtration rate, and drug transporters. This review also reports gender differences in pharmacokinetics and pharmacodynamics of cardiovascular agents, central nervous system acting agents and antiviral agents. In addition, it has been reported that females experience more adverse reactions such as coughing, tachycardia, nausea, vomiting, rash, hypersensitivity, hepatotoxicity, and metabolic disorder after taking cardiovascular, central nervous system acting and antiviral agents. Therefore, in order to provide optimal drug dosage regimens both in male and female, gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions must be considered.

Hyaluronidase, an enzyme that breaks down hyaluronic acid, has long been used to increase the absorption of drugs into tissue and to reduce tissue damage in cases of extravasation of a drug. With the increasing popularity of hyaluronic acid filler, hyaluronidase has become an essential drug for the correction of complications and unsatisfactory results after filler injection. For this reason, when performing procedures using hyaluronic acid filler, a sufficient knowledge of hyaluronidase is required. In order for hyaluronidase to dissolve a hyaluronic acid filler, it must interact with its binding sites within the hyaluronic acid. The reaction of a filler to hyaluronidase depends on the hyaluronic acid concentration, the number of crosslinks, and the form of the filler. Hyaluronidase is rapidly degraded and deactivated in the body. Therefore, in order to dissolve a hyaluronic acid filler, a sufficient amount of hyaluronidase must be injected close to the filler. If the filler is placed subcutaneously, injection of hyaluronidase into the filler itself may help, but if the filler is placed within a blood vessel, it is sufficient to inject hyaluronidase in the vicinity of the vessel, instead of into the filler itself. Allergic reactions are a common side effect of hyaluronidase. Most allergic reactions to hyaluronidase are local, but systemic reactions may occur in infrequent cases. Since most allergic responses to hyaluronidase are immediate hypersensitivity reactions, skin tests are recommended before use. However, some patients experience delayed allergic reactions, which skin tests may not predict.

Toxicity study of recombinant hepatitis B vaccine (LBD-008), a newly developed drug for acute and chronic hepatitis, was investigated in mice and guinea pigs. 1. Mice showed no production of antibodies against LBD-008 inoculated with aluminum hydroxide gel (Alum) as an adjuvant, judged by the heterologous anaphylaxis (PCA) test using rats. On the other hand, antibodies against ovalbumin (OVA) inoculated with alum were definitely detected. 2. In the studies with guinea pigs, both the inoculation of LBD-008 only and of LBD-008 with complete Freund's adjuvant (CFA) as an adjuvant did not produce positive reactions in any of homologous active systemic anaphylaxis (ASA). On the other hand, the inoculation of ovalbumin with complete Freund's adjuvant (CFA) produced positive reaction in both of PCA and ASA. 3. These findings suggested that LBD-008 has no antigenic potential in mice or guinea pigs.

Diamino-diphenyl-sulfone (Dapsone) is widely used in the treatment of leprosy and a variety of blistering skin diseases. It sometimes has adverse side effects with common usual doses, such as skin, nervous system, gastrointestinal tract, liver, kidney and hematologic toxicity. One of these side effects is a rare but serious hypersensitivity reaction called dapsone syndrome, which occurs several weeks after the initial administration of the drug and results in unpredictable, sometimes fatal outcomes. This report deals with a 13-year-old girl's case with typical features of dapsone syndrome that included fever, exfoliative dermatitis, jaundice, hemolytic anemia and pleural effusion after being treated with dapsone for four weeks.

A 11-year-old neutered male Maltese dog was vaccinated with a rabies vaccine (Rabisin^®, Boehringer Ingelheim International GmbH, Germany) subcutaneously at a local animal hospital. One hour after vaccination, purpura with edema was observed at the injection site and severe thrombocytopenia (0 K/μL) was noted on a complete blood count (CBC). No specific findings were found in serum chemistry, electrolyte, blood gas analysis, and coagulation tests. The patient was hospitalized and administered antihemorrhagic agents (vitamin K, desmopressin), antihistamines (chlorpheniramine) and corticosteroids (methylprednisolone sodium succinate). On a repeat CBC, mild anemia had developed, thrombocytopenia was still noted, and autoagglutination was observed on a saline agglutination test (SAT). A polymerase chain reaction panel for infectious agents (e.g., Babesia spp.) was negative. The diagnosis was secondary immune-mediated thrombocytopenia (IMT) with immune-mediated hemolytic anemia (IMHA) associated with vaccination. Therefore, the immunosuppressants (prednisolone, and mycophenolate mofetil) were administered. Six days after drug administration, new lesion was not observed, and the previous lesions were significantly improved. It gradually improved and 4 weeks after hematocrit and platelet recovered to normal levels. It was maintained for 6 months without recurrence of related symptoms. Based on patient's history and test results, the patient was diagnosed with Evans' syndrome associated with rabies vaccine.

Corticosteroids are widely used in the treatment of various diseases because of its potent antiinflammatory effect. According to recent knowledge, bronchial asthma is also chronic inflammatory disease. Therefore antiinflammtory agent such as cromoyln sodium and corticosteroid is highly recommended for treament of chronic bronchial asthma. Especially hydrocortisone succinate (Solu-Cortef) is commonly used for treament to acute asthmatic attack via intravenous injection due to have rapid therapeutic onset and short duration. Since Sunaga et al. reported acute asthma attack after hydrocortisone injection in 1973, several cases of bronchospam with or without angioedema and urticaria after intravenous injection of hydrocortisone have been reported. We experienced a case of severe bronchospasm and acute respiratory failure after intraveous injection of hydrocortisone succinate in 64 year-old female asthmatic patient who visited to emergency room for acute asthmatic attack. About 5 minites after Solu-Cortef injection, a severe bronchospasm with arterial hypoxemia was developed. In order to confirm the suspected relationship between the offending drug(Solu-Cortef) and acute bronchospasm, we examed intravenous and inhalation provocation test by hydrocortisone succinate and methylprednisolone(control). After administration of hydrocortisone succinate via intravenous and inhalation route, severe asthmatic attack occurred. But administration of intravenous methylprednisolone and orall triamcinolone and saline were not provoke bronchospasm. Skin test using hydrocortisone sodium succinate was also positive. Administration of hydrocortisone is very serious to asthmatic patient with hydrocortisone hypersensitivity. Therefore, the clinician must be have history taking about previous adverse reaction of steroid before its clinical use. And methylprednisone may be useful and safe drug to the treatment of acute asthmatic patient with hydrocortisone hypersensitivity.
