Intolerance or idiosyncrasy to acetylsalicylic acid (ASA) and other nonsteroidal anti-inflammatory drugs (NSAIDs) is a crucial problem because these drugs are frequently used in medical treatment. In this study, we tested whether nimesulide, a selective cyclooxygenase-2 (COX-2) inhibitor, might be a valid alternative for patients with histories of adverse reaction to ASA or NSAIDs. A single-blind, placebo-controlled oral challenge procedure was applied to 60 adult patients (19 male, 41 female; with a mean age of 40.31 +/- 10.44 years, range 20-68 years) with a reliable history of ASA/NSAIDs-intolerance. According to history, the clinical presentations of intolerance were urticaria/angioedema in 32 patients, anaphylactoid reaction in 2 patients, respiratory reaction in 19 patients, and respiratory and cutaneous reaction in 7 patients. Atopy was confirmed by means of skin prick test with inhalant allergens. Oral challenge protocol was started with 25 mg of nimesulide and the remaining 75 mg was given 1 hr later. During the challenge procedure, blood pressure, pulse, nasoocular, pulmonary, and cutaneous symptoms were monitored. Of the 60 patients tested, 55 (91.7%) tolerated the drug with no adverse reaction. Only five (8.3%) patients demonstrated a positive response to oral challenge. The clinical presentations of intolerance to nimesulide were urticaria/angioedema in three patients, mild rhinitis in one patient, and mild dyspnea in one patient. The atopy prevalence was higher, with a ratio of 41.7%, in patients with ASA/NSAIDs intolerance than that of the healthy adult population in Turkey (p < 0.05). We believe that nimesulide can be used as an alternative drug for patients with ASA/NSAIDs intolerance.

A forty-four-year-old Japanese female, who had persistant rhinorrhea, was administered Benza block tablets orally along with two other medicines. Immediately after ingestion, the patient displayed itching of the right upper eyelid, followed by coughing, sneezing, nasal discharge, nasal obstruction, nausea, vomiting, swelling of the face, and dyspnea. She had edema, a wheal extending from the face to the neck, and swelling of the eyelids and lips. Her symptoms subsided after treatment. Her reaction to ibuprofen, which was contained in the Benza Block tablets, was confirmed by a positive reaction to prick testing. From the results of these examinations, our patient was diagnosed as having anaphylaxis due to the ibuprofen in the Benza Block tablets. A review of the literature revealed no previous reports of anaphylaxis due to ibuprofen, although a few cases of ibuprofen urticaria have been reported.

A 15 year old female with uterus bicornis bicollis was admitted for operation. She had a history of atopic dermatitis and allergy to buckwheat, raw egg and latex. Two months previously she had developed whole body flushing during dental treatment, and latex glove used by the dentist had been suspected as the cause. Prior to the operation she underwent internal examination and intrauterine echogram in which a latex glove was carelessly used by another gynecologist who had not confirmed her past history. After 30 minutes, dyspnea and urticaria without itching, appeared suddenly. Blood pressure decreased to 80/50 mmHg and heart rate increased to 120 beats.min-1. She was then transferred to our ICU. Methylprednisolone was administered intravenously for dyspnea and circulatory collapse. After 3 hours, the patient made an uneventful recovery. The increased plasma latex protein-specific IgE levels confirmed anaphylaxis to latex. The increasing incidence of potentially life-threatening allergic reactions to latex has caused mounting concern over recent years. We may suspect latex allergy when an anaphylaxic reaction or shock of unknown origin occurs. In hospitals, latex free products must be prepared for use with latex allergic patients and for protection of medical staff with this allergy.

Anaphylactic shock is a life-threatening allergic reaction with cardiovascular collapse. The cardiovascular collapse may occur suddenly without warning signs or may be preceded by symptoms such as pruritus, wheezing, dyspnea, urticaria, pallor, digestive symptoms, and weakness. Food allergens, injected drugs and hymenoptera stings are the main etiologies. Anaphylactic shock requires an emergency treatment with immediate intramuscular or subcutaneous epinephrine injection. Subsequent avoidance of the inciting allergens is mandatory together with the availability of a first aid kit including ready-to-use epinephrine syringes. Besides its absolute necessity in any doctor's office, such first aid kits should be available in any children's group.

Exposure to wood dusts may cause various skin and mucosal symptoms. Allergic dermatoses, caused by wood dusts, diagnosed at the Finnish Institute of Occupational Health during 1976-1999 are reported here. 16 had allergic contact dermatitis and, 2 had contact urticaria. 9 men (3 cabinet makers, 3 joiners, 1 carpenter, 1 knifemaker and 1 machinist) were mainly exposed to tropical hardwoods. 1 man had dermatitis caused by western red cedar. 5 patients, 3 men and 2 women, were exposed to Finnish pine or spruce dusts, and 1 man to aspen. 7 also had rhinitis, 4 asthma or dyspnoea and 3 conjunctivitis. On patch testing, 10 men reacted to 9 different wood dusts, including teak (5), palisander (3), jacaranda (2), mahogany (2), walnut (2) and obeche (1). Reactions to wood allergens, including lapachol (2), deoxylapachol (1), (R)-3,4-dimethoxydahlbergione (2), 2,6-dimethoxy-1,4-benzoquinone (1), mansonone A (2) and salicyl alcohol (1), were noted in 4 cases. All but 1 of 5 patients exposed to pine or spruce dusts reacted to the sawdusts, all 5 to colophonium, 3 to abietic acid, 2 to tall oil resin, 3 to wood tar mix and 4 to other wood gum resins. Of the 2 CU patients, 1 was prick and RAST positive to obeche, 1 reacted with urticarial dermatitis to punah wood dust on chamber exposure. Occupational allergic dermatoses are mainly caused by the dusts of hardwoods, mostly due to Type IV allergy, but may also be caused by softwood dusts. Patch tests can be done with wood dusts, but should be confirmed by patch testing with wood allergens if possible.

Latex devices release allergenic proteins which are responsible for immune IgE mediated reactions. Casual surgical gloves are most often responsible for contact urticaria. Other allergic manifestations include conjunctivitis, rhinitis, asthmatiform dyspnoea and diverse gastro-intestinal troubles. Cardiovascular collapse and anaphylactic shock are possible. Physicians and the paramedical staff are particularly affected by the allergy to latex proteins. Multi-operated patients and those under prolonged health care using latex-made medical probes also present a high-risk group for this type of allergy.

A male athlete suffered complete respiratory arrest after collapsing at the entrance to an Accident and Emergency Department of a hospital. He was resuscitated and recovered fully after several hours. He had multiple wheals on both legs and had complained of severe breathlessness before collapsing. The athlete had run through a wheat field, upon finding his usual pathway overgrown, which had caused wheat pollen to be released. He had been a mild asthmatic for 30 years and had recalled some mild urticaria after exercise but had never experienced exercise-induced asthma, or hay fever. Subsequent allergy tests showed negative for wheat but positive for house dust mite and grass mix. It is possible that the symptoms were triggered either by the running itself, inhalation of allergens other than wheat pollen, skin abrasions caused by contact with wheat stalks, or a combination of these factors.

Following approval of the fat replacer olestra for use in preparing savory snacks, Procter & Gamble implemented a postmarketing surveillance program to monitor marketplace introduction. Three and one-half percent of all health effects reported by consumers to the surveillance toll-free number were allergy-type symptoms (e.g., rash, itching, edema, hives, dyspnea). Because of these reports, we investigated whether olestra or some component of olestra snacks was a likely allergen in some subset of the population. A single center, randomized, double-blind, placebo-controlled, within-subject crossover food challenge study was conducted to confirm or refute the allergenicity of olestra snacks. Of the 65 subjects who reported symptoms consistent with immediate hypersensitivity to olestra's postmarketing surveillance program, 14 men and women traveled to the Arkansas Children's Hospital Research Institute to participate in this study. Each subject underwent a standard skin prick test at the beginning of the study, to help determine what component, if any, of the olestra product was allergenic. Following the skin prick test, subjects ate in random order, olestra-containing potato chips and regular fat-containing potato chips. The dose of potato chips consumed at each challenge was at least the amount alleged to have caused the symptoms that prompted the consumer to phone the postmarketing surveillance toll-free number. No subject experienced an allergic reaction after consuming the olestra-containing chips. Nor did any subject elicit a positive response to olestra following the skin prick testing. Two subjects had positive reactions consistent with immediate hypersensitivity after consuming the regular-fat, placebo potato chips. The results of this study confirm that olestra is unlikely to have an allergenic potential.

Post-marketing experience shows zanamivir to be well tolerated in the general population for the treatment and prophylaxis of influenza type A and B infections. Individuals at high-risk of influenza have potentially more to gain from zanamivir therapy. We assessed safety and tolerability findings from treatment and prophylaxis studies in over 982 high-risk subjects. Eight treatment studies involving high-risk subjects have been conducted with zanamivir 10 mg twice daily for 5 days. The incidence and pattern of adverse events was similar in zanamivir and placebo recipients. Lower respiratory adverse events reported by recipients receiving zanamivir occurred at similar or lower frequencies to those receiving placebo. In one treatment study involving 525 patients with asthma or chronic obstructive pulmonary disease, zanamivir recipients had a small but significantly increased mean morning peak expiratory flow rate (PEFR) and evening PEFR compared with placebo during the treatment period (days 1 to 5). Eight prophylaxis studies have been conducted, five in family or community settings and three in nursing homes. Data from these studies demonstrate that zanamivir is well tolerated for prophylaxis. In nursing home studies, where 90% of participants were high risk, the pattern and incidence of adverse events were similar to that reported in otherwise healthy individuals, and similar to both placebo and rimantadine, a comparator in one study. In treatment and prophylaxis studies the incidence and pattern of adverse events in participants > or =65 years or with chronic underlying respiratory disorders was similar for zanamivir or placebo recipients. Overall, zanamivir was well tolerated and study drug discontinuations were low. A small number of deaths have been reported in studies of high-risk elderly individuals, but none were considered to be related to zanamivir. Thus clinical studies have demonstrated that zanamivir has a comparable safety profile in high-risk and otherwise healthy recipients. Approximately 1.72 million treatment courses of zanamivir were prescribed up to the end of January 2001. Many spontaneous adverse event reports received since marketing, a third of these from non-healthcare professionals, reflect the underlying condition being treated. However, a number of events have resulted in changes to the zanamivir prescribing information, including rare reports of bronchospasm, dyspnoea, rash, urticaria and allergic type reactions including facial and oropharyngeal oedema. The reported safety profile of zanamivir, for treatment and prophylaxis of high risk subjects with influenza type A and B infections supports its continued use in these individuals who are likely to benefit most.

A 71-year-old Japanese male with myelodysplastic syndrome progressing to overt leukaemia and hepatocellular carcinoma developed dyspnea and urticaria immediately after infusion of platelet concentrate (PC). He exhibited an identical reaction following blood transfusion. Serum haptoglobin was undetectable. The patient was determined to be homozygous for Hp(del) by polymerase chain reaction (PCR). Antibody to haptoglobin was detected by enzyme-linked immunosorbent assay (ELISA) and Western blot analysis. No antibodies against human leucocyte antigen (HLA) or platelet-specific antigens were detected. Washed PC and washed red blood cells were effective in preventing the transfusion-related anaphylactoid reactions.
