TL;DR: The comparison with the three previous surveys confirms that the mechanism of about half of the anaphylatoid reactions occurring during anaesthesia is of immune origin, due to specific IgE antibodies.
Abstract: Since 1984 an epidemiological survey of anaphylactoid reactions occurring during anaesthesia has been obtained in France with regular repeated inquiries by the Perioperative Anaphylactoid Reactions Study Group (Gerap). The members of this group collected during the study period cases of patients having suffered from an anaphylactoid reaction and subsequently tested in their allergoanaesthetic outpatient clinic. The three previous surveys published in the Annales francaises d'anesthesie et de reanimation in 1990, 1993 (in English) and 1996 included 1,240, 1,585 and 1,730 patients respectively. The current survey concerned 1,648 patients, tested by the GERAP (38 diagnostic centres) from July 1994 to December 1996. The diagnostic tests for IgE anaphylaxis were cutaneous tests (prick tests and intradermal tests), which minimal dilutions for specific positive skin test were previously determined by comparison with control subjects. The cutaneous tests were performed by all the centres. These tests were associated, in 29 centres, with the detection of specific IgEs against quaternary ammonium compound and inhibition test, and detection of IgEs against propofol, thiopental and latex. Moreover, leukocyte histamine release test was performed in seven centres. The mechanism of the reaction was: anaphylaxis in 692 patients (characteristic clinical symptoms and positive allergological tests), anaphylactoid reactions in 611 patients (characteristic clinical symptoms and negative allergological tests), and other causes in 345 patients (unusual clinical symptoms and negative allergological tests). An immune mechanism was found in 53% of the reactions, with characteristic clinical symptoms occurring during anaesthesia. The 692 cases of anaphylaxis were due to 734 substances (double anaphylaxis in 42 patients): muscle relaxants (61.6%), latex (16.6%), antibiotics (8.3%), hypnotics (5.1%), colloids (3.1%), opioids (2.7%) and others (2.6%) among which aprotinin (four cases) ethylene oxide (five cases) local anaesthetics (two cases). The muscle relaxants implicated in anaphylactic reactions included: vecuronium (n = 130), atracurium (n = 107), suxamethonium (n = 106), pancuronium (n = 41), rocuronium (n = 41), mivacurium (n = 18), and gallamine (n = 9). These results reflected French anaesthetic practice, except for suxamethonium (5% of the French market share of curares). In 70% of the patients who were allergic to one muscle relaxant, cross-sensitivity was found with the other relaxants. The comparison with the three previous surveys confirms that the mechanism of about half of the anaphylatoid reactions occurring during anaesthesia is of immune origin, due to specific IgE antibodies. Muscle relaxants remain the most common cause of anaphylaxis, followed by latex whose incidence seems to decrease, whereas the incidence of anaphylaxis to antibiotics increases. Incidence of reactions to suxamethonium decreased, corresponding however to one quarter of all muscle relaxant anaphylaxis, similar with vecuronium and atracurium. For this survey, more clinical information was obtained in 583 patients, allowing the following conclusions: reactions were always more severe in case of anaphylaxis than nonspecific histamine release; reactions occurred more frequently in females (F/M = 2.5); 17% of patients allergic to a muscle relaxant were never anaesthetized beforehand; a history of reactions during previous anaesthetics was a risk factor for a reaction during subsequent anaesthetics; neither drug allergy nor atopy (except for latex allergy) were a predisposing factor for reactions with anaesthetic agents. Considering that in 1996, 8 million anaesthetics were administered in France, of which 2.5 million included the use of muscle relaxants, the overall incidence for anaphylactic reactions, all agents included, was evaluated as 1 in 13,000 anaesthetics, while the incidence of anaphylaxis to muscle relaxants was 1 in 6,500 anaesthetics.

TL;DR: The results of a 2-yr survey of reactions observed during anesthesia in France further corroborate the need for systematic screening in the case of anaphylactoid reaction during anesthesia and for the constitution of allergoanesthesia centers to provide expert advice to anesthesiologists and allergists.
Abstract: Background Anaphylactic and anaphylactoid reactions occurring during anesthesia remain a major cause of concern for anesthesiologists. The authors report the results of a 2-yr survey of such reactions observed during anesthesia in France. Methods Between January 1, 1999, and December 31, 2000, 789 patients who experienced immune-mediated (anaphylaxis) or nonimmune-mediated (anaphylactoid) reactions were referred to one of the 40 participating centers. Anaphylaxis was diagnosed on the basis of clinical history, skin tests, and/or specific immunoglobulin E assay. Results Anaphylactic and anaphylactoid reactions were diagnosed in 518 cases (66%) and 271 cases (34%), respectively. The most common causes of anaphylaxis were neuromuscular blocking agents (NMBAs) (n = 306, 58.2%), latex (n = 88, 16.7%), and antibiotics (n = 79, 15.1%). Rocuronium (n = 132, 43.1%) and succinylcholine (n = 69, 22.6%) were the most frequently incriminated NMBAs. Cross-reactivity between NMBAs was observed in 75.1% of cases of anaphylaxis to an NMBA. No difference was observed between anaphylactoid and anaphylactic reactions when the incidences of atopy, asthma, or drug intolerance were compared. However, atopy, asthma, and food allergy were significantly more frequent in the case of latex allergy when compared with NMBA allergy. Clinical manifestations were more severe in anaphylaxis. The positive predictive value of tryptase for the diagnosis of anaphylaxis was 92.6%; the negative predictive value was 54.3%. The diagnostic value of specific NMBA immunoglobulin E assays was confirmed. Conclusions These results further corroborate the need for systematic screening in the case of anaphylactoid reaction during anesthesia and for the constitution of allergoanesthesia centers to provide expert advice to anesthesiologists and allergists.

TL;DR: Clinical reactions to neuromuscular blocking drugs were more severe than to latex, and the diagnostic value of specific IgE assays was confirmed, consistent with changes in the epidemiology of anaphylaxis related to anaesthesia.
Abstract: Between January 1, 1997 and December 31, 1998, 467 patients were referred to one of the allergo-anaesthesia centres of the French GERAP (Groupe d'Etudes des Reactions Anaphylactoides Peranesthesiques) network and were diagnosed as having anaphylaxis during anaesthesia. Diagnosis was established on the basis of clinical history, skin tests and/or a specific IgE assay. The most frequent cause of anaphylaxis was a neuromuscular blocking agent (69.2%). Latex was less frequently incriminated (12.1%) than in previous reports. A significant difference was observed between the incidence of anaphylactic reactions observed with each neuromuscular blocking agent and the number of patients who received each drug during anaesthesia in France throughout the study period (P<0.0001). Succinylcholine and rocuronium were most frequently incriminated. Clinical reactions to neuromuscular blocking drugs were more severe than to latex. The diagnostic value of specific IgE assays was confirmed. These results are consistent with changes in the epidemiology of anaphylaxis related to anaesthesia and are an incentive for the further development of allergo-anaesthesia clinical networks.

TL;DR: L'origine anaphylactique de l'accident grave a ete prouvee chez 443 d'entre eux ; pour la majorite de ceux-ci (263), un curarisant a ee responsable du choc.
Abstract: The details of 826 patients referred to an Anaesthetic Allergy Clinic over a 17-year period are described. 443 were classified as having severe immediate anaphylactic reactions and in the majority of these (263) a muscle relaxant was involved. In Australia, the most common cause of a reaction is alcuronium, which probably reflects usage, although it is the most commonly found to give a positive skin test in relaxant reactors. Suxamethonium and atracurium appear to have an incidence of reactions greater than predicted by market share and pancuronium and vecuronium appear safer both on incidence of reactions and on positive skin tests in reactors. The incidence of reactions is between 1:10,000 and 1:20,000 anaesthetics. Patients who react have greater incidence of allergy, atopy, asthma and previous reactions than non reactors. Previous exposure is usually apparent in reactors to induction agents but not muscle relaxants. Cardiovascular collapse is the most common presenting problem and is the only problem in 10%. Skin changes are the next most common and then bronchospasm which may be transient and is the hardest feature to treat. With an investigation protocol based on history, skin and RIA testing subsequent anaesthesia is usually safe.

TL;DR: It is concluded that increased mast cell tryptase concentrations are a valuable indicator of an anaphylactic reaction during anaesthesia and their presence favours an IgE-mediated cause but does not always distinguish betweenAnaphylactoid and anaphlyactoid reactions, and patients in whom mast celltrypt enzyme concentrations are not increased still require skin testing.
Abstract: Increased concentrations of mast cell tryptase are a highly sensitive indicator of anaphylactic reactions during anaesthesia. We obtained serum specimens from 350 patients after possible anaphylactic reactions during anaesthesia. Serum was collected from patients in our own institution (27), and transported by mail and courier from other hospitals in response to a request in the medical literature (323). Concentrations of mast cell tryptase were measured in 416 specimens. Intradermal testing was performed in 217 patients and radioimmunoassay for drug-specific antibodies with serum in 198 patients. Mast cell tryptase concentrations were increased in 158 patients, equivocal in 10 and not increased in 182. There was a significant difference in the incidence of positive intradermal tests, radioimmunoassay tests and evidence of an IgE-mediated reaction in patients whose mast cell tryptase concentrations were increased. Seven of 143 patients whose mast cell tryptase concentrations were not increased at appropriate sampling times had positive tests for IgE antibodies, and in 33 of 158 patients with increased mast cell tryptase concentrations no IgE antibodies were detected. We conclude that increased mast cell tryptase concentrations are a valuable indicator of an anaphylactic reaction during anaesthesia. Their presence favours an IgE-mediated cause but does not always distinguish between anaphylactoid and anaphylactoid reactions, and patients in whom mast cell tryptase concentrations are not increased still require skin testing.

TL;DR: An epidemiological inquiry was carried out in departments of anaesthesia and immunology in French University and General Hospitals and among those who were already known to have an allergo-anaesthesia outpatient clinic to find out how many patients had undergone diagnostic investigations after as well as an anaphylactoid reaction during an anaesthetic in 1990 and 1991.
Abstract: An epidemiological inquiry was carried out in departments of anaesthesia and immunology in French University and General Hospitals, as well as among those who were already known to have an allergo-anaesthesia outpatient clinic. This inquiry aimed to find out how many patients had undergone diagnostic investigations after as well as an anaphylactoid reaction during an anaesthetic in 1990 and 1991, as well as the demographic data, the kind of assessment, the accident mechanism and the drugs involved. Twenty-one French centres replied to the questionnaire and a series of 1,585 patients tested over a two-year period was thus collected. There were three female patients to one male. The reactions occurred mostly in the adult (80%), but 9% were observed in children. Allergological tests for IgE-dependent anaphylaxis were the skin tests (21 centres), combined with radioimmunological assays of specific serum antibodies to muscle relaxants (10 centres), propofol (9 centres), latex (5 centres), leukocyte histamine release (9 centres) and human basophil degranulation test (4 centres). The criteria for a positive result were the same for all centres. Among these 1,585 patients, 813 were recognized as having had a reaction of immunological origin (52%). The substances involved were identified in these 813 patients as being muscle relaxants (70%), latex (12.6%), hypnotics (3.6%), benzodiazepines (2.0%), opioids (1.7%), colloids (4.7%), and antibiotics (2.6%). Suxamethonium was responsible for 43% of the IgE-dependent reactions involving a muscle relaxant, vecuronium for 37%, pancuronium for 13%, alcuronium for 7.6%, atracurium for 6.8% and gallamine for 5.6%.(ABSTRACT TRUNCATED AT 250 WORDS)

TL;DR: The reactive‐solid phase which was used in the present work significantly increased the sensitivity of detection of anti‐muscle relaxant IgE in serum.
Abstract: Until now, immunoassays for detection of anti-muscle relaxant IgE in serum have been performed with the drug coupled to epoxy-activated Sepharose or to RAST papers dics. In the present work we have used a quaternary ammonium-Sepharose in which the quaternary ammonium reactive group (choline chloride) was directly coupled to Sepharose via an ether linkage. 50 μl of the quaternary ammonium solid phase (QAS) was incubated with 50 μl of serum for 3 h, washed, incubated 18 h with 125I-anti-IgE and washed again. The results were expressed as the percentage of 125I-anti-IgE adsorbed onto the solid phase. The results were at 1.3±0.5% for 20 control sera, with an upper normal limit estimated to 2.3%. The within-run reproducibility ranged from 3.2% to 10.0%. The results were significantly correlated with those obtained with either alcuronium-epoxy-Sepharose, choline-epoxy-Sepharose, the RAST-alcuronium or with the RAST-succinyl choline (respectively, r - 0.66, r = 0.80, r = 0.81, r = 0.40 and r = 0.85). The values obtained with the sera of 83 patients ranged from 0.3 to 38.5%. The sensitivity was estimated at 87.9%, 66.7% and 40.7% with the QAS-RIA, the RAST-succinyl choline and the RAST-alcuronium, respectively. The inhibition of adsorption of specific IgE onto the gel ranged from 13.0 to 90.6% in presence of 130 nmol of soluble muscle relaxants. In 83.3% of 30 cases, the highest inhibition was obtained with the muscle relaxant which was clinically incriminated. In conclusion, the reactive-solid phase which was used in the present work significantly increased the sensitivity of detection of anti-muscle relaxant IgE in serum.
