A portable surface plasmon resonance (SPR) sensor for the detection of immunoglobulin A in plasma. Transfusion 2024; 64:881-892. [PMID: 38591151 DOI: 10.1111/trf.17818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 03/05/2024] [Accepted: 03/20/2024] [Indexed: 04/10/2024]
Abstract
BACKGROUND A life-threatening anaphylactic shock can occur if a patient with undiagnosed immunoglobulin A (IgA) deficiency (i.e., IgA levels <500 ng/mL) receives IgA-containing blood, hence the need for a rapid, point-of-care (POC) method for IgA deficiency screening. Enzyme-linked immunosorbent assay (ELISA) is routinely used to detect IgA, but this method requires trained specialists and ≥24 h to obtain a result. We developed a surface plasmon resonance (SPR)-based protocol to identify IgA-deficient patients or donors within 1 h. MATERIALS AND METHODS The SPR sensor relies on the detection of IgAs captured by primary antibodies adsorbed on the SPR chip and quantified with secondary antibodies. The sensor was calibrated from 0 to 2000 ng/mL in buffer, IgA-depleted human serum, and plasma samples from IgA-deficient individuals. A critical concentration of 500 ng/mL was set for IgA deficiency. The optimized sensor was then tested on eight plasma samples with known IgA status (determined by ELISA), including five with IgA deficiency and three with normal IgA levels. RESULTS The limit of detection was estimated at 30 ng/mL in buffer and 400 ng/mL in diluted plasma. The results obtained fully agreed with ELISA among the eight plasma samples tested. The protocol distinguished IgA-deficient from normal samples, even for samples with an IgA concentration closer to critical concentration. DISCUSSION In conclusion, we developed a reliable POC assay for the quantification of IgA in plasma. This test may permit POC testing at blood drives and centralized centers to maintain reserves of IgA-deficient blood and in-hospital testing of blood recipients.

Case Report: A Rare Case of Iodixanol-Induced Anaphylactic Shock in Cerebral Angiography. J Asthma Allergy 2024; 17:361-367. [PMID: 38623449 PMCID: PMC11018123 DOI: 10.2147/jaa.s460263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 04/01/2024] [Indexed: 04/17/2024] Open
Abstract
Background Adverse reactions induced by isoosmolar contrast medium (iodixanol) are mostly mild, with rashes and headaches being the most common. Although anaphylactic shock has been reported, no related incidents have been documented on cerebral angiography. Objective This article reports a serious case of anaphylactic shock possibly induced by iodixanol and provides an overview of the case report. Case Summary A 65-year-old female with persistent headaches for nearly six months and CTA examination revealed multiple intracranial aneurysms. After two treatments, she returned to the hospital for aneurysm of reexamination a month ago. Following a preoperative assessment, cerebral angiography was performed. Three minutes after the procedure, the patient experienced dizziness, increased heart rate, followed by hypotension (BP 90/43 mm Hg), a sudden drop-in heart rate (HR 68 bpm), and a drop in SpO2 to 92%. Intravenous dexamethasone for anti-allergic were administered immediately, along with therapy through oxygen-inhalation. However, the patient then developed limb convulsions, unresponsiveness, and was urgently given diazepam for sedation and sputum aspiration to maintain airway patency. Blood pressure decrease to 53/29 mm Hg, and SpO2 readings were unavailable. Intravenous dopamine to elevates blood pressure, and assists breathing by intubating in the endotracheal. After 3 minutes, as the blood pressure remained undetectable, intermittent intravenous epinephrine 1mg was administered to raise the blood pressure, gradually restoring it to 126/90 mm Hg, and SpO2 increased to 95%. The patient was diagnosed with iodixanol-induced anaphylactic shock and urgently transferred to the NICU for monitoring and treatment. The patient died despite immediate treatment. Conclusion A 65-year-old female developed serious anaphylactic shock during cerebral angiography after receiving iodixanol. Although iodixanol is considered one of the safest iodinated contrast mediums (ICM), clinicians should be aware of its the potential for serious hypersensitivity reactions that can lead to fatal and life-threatening events.

Adverse reactions of piperacillin: A literature review of case reports. Open Med (Wars) 2024; 19:20240931. [PMID: 38623456 PMCID: PMC11017182 DOI: 10.1515/med-2024-0931] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 01/26/2024] [Accepted: 02/16/2024] [Indexed: 04/17/2024] Open
Abstract
Aim This study aimed to summarize case reports of adverse drug reactions (ADRs) caused by piperacillin and explore their effects on human organs in real-world settings. Method Case reports of piperacillin ADRs were collected by searching databases such as PubMed, Embase, Web of Science, CNKI, WanFang, and VIP from inception to December 2022. Results A total of 170 patients were ultimately included. The results revealed that ADRs caused by piperacillin were primarily associated with the entire body, followed by the blood system, skin and soft tissues, and the nervous system. The most frequently reported cases included anaphylactic shock, drug fever, rash, and thrombocytopenia. The most severe ADRs were identified as anaphylactic shock and bullous epidermal necrolysis. Furthermore, a comparison was made between systemic adverse reactions caused by piperacillin as a single drug and two composite preparations of piperacillin/β-lactamase inhibitor. ADRs not mentioned in the instructions included convulsions or hallucinations and Kounis syndrome (KS). Conclusion This review suggests that the most severe ADRs associated with piperacillin are toxic epidermal necrolysis and anaphylactic shock. Rare ADRs caused by piperacillin, such as myoclonic jerks, hallucinations, and KS, were identified. The most common symptom with domestic preparations of piperacillin/sulbactam and piperacillin sodium was dyspnea.

Type III Kounis Syndrome Caused by Iodine Contrast Media After Improvement of Allergic Symptoms. Cureus 2024; 16:e55514. [PMID: 38449915 PMCID: PMC10915903 DOI: 10.7759/cureus.55514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/04/2024] [Indexed: 03/08/2024] Open
Abstract
Kounis syndrome is an acute coronary syndrome (ACS) caused by an allergic reaction that almost always occurs immediately and simultaneously with allergic symptoms. We present a case of Kounis syndrome type III that developed after complete resolution of contrast-induced anaphylaxis in a 60-year-old man with a coronary stent placed in the proximal left anterior descending (LAD) artery branch for ischemic heart disease. Contrast-enhanced computed tomography revealed anaphylactic shock. Symptoms quickly improved with intramuscular adrenaline injection; however, chest pain appeared after approximately 30 min. ECG revealed ST-wave elevation in the precordial leads. Coronary angiography revealed acute stent thrombosis with total occlusion of the proximal LAD, and percutaneous coronary angioplasty was performed. We diagnosed Kounis syndrome based on the allergic symptoms and ACS. Because some cases of Kounis syndrome develop after anaphylactic symptoms have resolved, it is advisable to follow-up patients with allergic symptoms and pay attention to chest symptoms and ECG changes, especially when they have a history of noted or treated coronary artery disease.

Abstract
Hydrochlorothiazide (HCTZ) is a commonly used diuretic antihypertensive drug that can cause electrolyte disorders, hyperglycemia and hyperuricemia as well as rare life-threatening adverse drug reactions. These include non-cardiogenic pulmonary edema, interstitial pneumonia, angioedema and aplastic anemia. The present report describes a case of a 59-year-old man who developed a hypersensitivity reaction to HCTZ. Specifically, the patient presented with symptoms of cough, chest tightness and shortness of breath, with pneumonic consolidation on chest CT and elevated levels of white blood cell count, neutrophil percentage, C-reactive protein and procalcitonin. A presumptive diagnosis of severe pneumonia was made initially. However, during the gradual recovery of the patient through treatment, he mistakenly ingested HCTZ containing losartan potassium intended for another patient, which resulted in symptoms similar to those observed upon admission. Upon further inquiry into the medical history, it was revealed that the patient had also taken irbesartan/HCTZ 4 h prior to hospitalization. There was no evidence of a pathogenic infection. Therefore, HCTZ-induced anaphylactic reaction was considered to be the most likely etiology for his severe shock. Treatments including epinephrine, methylprednisolone and respiratory support were administered. After 7 days, the patient was transferred from the Respiratory Intensive Care Unit [The Affiliated Jiangning Hospital of Nanjing Medical University (Nanjing, China)] to a general ward. During the follow-up, 12 months after advising the patient to discontinue HCTZ, there had been no recurrence of the aforementioned symptoms. At the time of publication, the patient is currently alive.

Anaphylactic shock following the mad honey consumption: a case report. Ann Med Surg (Lond) 2024; 86:1120-1123. [PMID: 38333261 PMCID: PMC10849406 DOI: 10.1097/ms9.0000000000001610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 12/03/2023] [Indexed: 02/10/2024] Open
Abstract
Introduction Mad honey consumption is a common practice in Nepal for medicinal and consumption purposes, but it can lead to severe adverse effects. Grayanotoxin I and Grayanotoxin III isoforms found in rhododendron interfere with voltage-gated sodium channels resulting in gastrointestinal symptoms, and cardiovascular effects such as low blood pressure, abnormal heart rhythms, cardiac arrest, and abnormal electrical conduction in the heart, as well as rare central nervous system disorders. Here the authors report a case of Mad honey consumption leading to anaphylactic shock along with its investigations and management. Case presentation The authors present a case of a 51-year-old female who developed anaphylactic shock after consuming mad honey. The patient experienced symptoms including nausea, vomiting, abdominal pain, sweating, dizziness, facial and lip swelling, but no chest pain, loss of consciousness, abnormal body movement, or dyspnoea. The patient had no prior medical conditions, regular medications, or history of allergic reactions to honey or pollen. Discussion Mad honey intoxication is caused by grayanotoxins, with distinct cardiac effects for different types of grayanotoxins. Symptoms include bradycardia, hypotension, abdominal pain, dizziness, and nausea, which subsided within 24 h following the initial management. The presence of grayanotoxin can be detected using specialized instrumentation, but it may not be available in all medical facilities. Co-intoxication with alcohol or propolis may also occur. Conclusion This case highlights the importance of recognizing and managing complications associated with mad honey consumption, particularly in regions where it is prevalent. Prompt medical attention is advised if unusual symptoms occur after honey consumption.

Abstract
Background Kounis syndrome (KS) is an underdiagnosed disease. The management of the disease remains elusive because of its infrequency. Case Presentation A 78-year-old man with anaphylactic shock was admitted to our hospital 2 h after multiple bee stings. After recovering from an anaphylactic reaction, he presented with chest pain with ST elevation. We diagnosed him with KS. After a continuous intravenous infusion of vasodilators, his chest pain and ST elevation improved. However, chest pain with ST-segment elevation recurred the next day. Coronary angiography revealed severe stenosis in the middle left anterior descending coronary artery, and drug-eluting stents were implanted. The patient was discharged on foot after treatment for heart failure. Conclusion KS, in which anaphylaxis and acute coronary syndrome occur simultaneously, can recur repeatedly after an initial anaphylactic reaction; however, it could be delayed or it could present simultaneously with the anaphylactic reaction. Therefore, long-term observation is important.

Abstract
Antibiotics are known to be able to cause hypersensitivity reactions through various mechanisms. We present a case of drug-induced immune thrombocytopenia (DITP) and anaphylactic shock occurring simultaneously in a dog after the administration of two classes of antibiotics, namely trimethoprim-sulfamethoxazole (TMP-SMX) and amoxicillin-clavulanate (AMC). The patient recovered completely from DITP on discontinuation of TMP-SMX and the anaphylactic shock caused by AMC was treated with intensive care. DITP is a rare adverse drug reaction (ADR), and anaphylactic shock is a life-threatening ADR. This is the first case report of a dog manifesting two types of hypersensitivity reactions caused by two antibiotics.

Abstract
An allergy to insect stings is one of the most frequent causes of anaphylactic reactions. Such reactions can be fatal, even on the first reaction, although it very rarely happens. The use of veno-arterial extracorporeal membrane oxygenation (VA ECMO) in refractory anaphylactic shock was previously described. We report a case of a 31-year-old female who presented with refractory anaphylactic shock after bee stings without the presence of cutaneous manifestations other than the rashes in her neck. The toxic component of bee venom and systemic allergic response plays a vital role in pathophysiology. She did not respond to conventional advanced life support, but following urgent VA ECMO, she survived neurologically intact. Despite an uncommon indication for anaphylaxis, ECMO support may be possible and effective in patients with refractory shock.

Refractory cardiac arrest caused by type I Kounis syndrome treated with adrenaline and nicorandil: A case report. Medicine (Baltimore) 2023; 102:e34535.

Abstract
RATIONALE Kounis syndrome is a rare but life-threatening anaphylactic reaction that can lead to acute coronary syndrome and cardiac arrest, and requires prompt diagnosis. Adrenaline, which is used to treat anaphylaxis, may cause coronary vasoconstriction and worsen ischemia, whereas coronary vasodilators may dilate systemic vessels and exacerbate hypotension. Delayed diagnosis of Kounis syndrome and inadequate therapeutic intervention may thus lead to a poor outcome. PATIENT CONCERNS A 59-year-old man was treated for sepsis due to a liver abscess. Following administration of daptomycin, the patient developed severe anaphylactic shock leading to refractory cardiac arrest. Because conventional cardiopulmonary resuscitation was ineffective, extracorporeal cardiopulmonary resuscitation was considered as an alternative approach. DIAGNOSES On bedside monitoring during cardiopulmonary resuscitation, unexpected ST-segment elevation was found on lead II electrocardiogram. Accordingly, the patient was clinically diagnosed with Kounis syndrome. INTERVENTIONS Nicorandil (6 mg/h), a coronary vasodilator with minimal blood pressure effects, was administered along with high doses of vasopressors, including adrenaline 0.2 µg/kg/min. OUTCOMES After the initiation of nicorandil administration, the patient achieved return of spontaneous circulation and did not require extracorporeal cardiopulmonary resuscitation. Based on the elevated serum tryptase level, normal creatine kinase-MB range, and lack of stenosis on coronary angiography, the patient was definitively diagnosed with type I (coronary vasospasm) Kounis syndrome. He was subsequently transferred to the referring hospital without neurological sequelae. LESSONS If anaphylaxis leads to refractory shock and cardiac arrest, ischemic changes on the electrocardiogram should be investigated to identify underlying Kounis syndrome. In addition to adrenaline, coronary dilators are the definitive treatment. Nicorandil may be a useful treatment option because of its minimal effect on blood pressure.

Abstract
The most common cause of vasoplegic shock in critical care is sepsis. However, although rarely and only in specifically sensitised individuals previously bitten by a tick, red meat may provoke a delayed allergic reaction called an alpha-gal syndrome. We present a case of a protracted life-threatening manifestation of alpha-gal syndrome, which, due to an unusual absence of typical features of anaphylaxis can masquerade as septic shock and calls attention to the premature diagnostic closure as a contributor to diagnostic error. Alpha-gal syndrome is a relatively new, but increasingly recognised health issue. We propose that alpha-gal syndrome should be considered in the differential diagnosis of vasoplegic shock of unclear aetiology even in the absence of typical allergic symptomatology and typical allergen exposure since alpha-gal is present in a wide variety of carriers. LEARNING POINTS Alpha-gal syndrome, otherwise known as "red meat allergy", is a potentially life-threatening allergic syndrome induced by the immunological properties of tick saliva.A typical case of alpha-gal syndrome is a patient bitten by a tick who develops an allergic reaction, anaphylaxis or anaphylactic shock even after an ingestion of a significant amount of alpha-gal, typically present in red mammalian meat or organs.As global warming continues, we may expect tick-borne diseases to spread wider around the globe and due to the possibility of complete absence of typical allergic symptomatology and the delayed onset of symptoms, this syndrome needs to be considered when encountering vasoplegic shock of uncertain origin.

Abstract
BACKGROUND Comparative hypersensitivity risk profile of frequently-used iodinated contrast media (ICM) may be required for their safer use. OBJECTIVE To explore the association between hypersensitivity reactions (HSRs) and specific ICM, as well as to characterize the spectrum of ICM-related HSRs. METHODS Disproportionality analysis and proportionality test were performed to assess the safety profile of ICM-related HSRs and compare the frequency ratio of specific HSRs in diverse age, sex, and country subgroups. Reports downloaded from the FDA Adverse Event Reporting System (FAERS) and data on the national usage of individual ICM were used for the above analysis. RESULTS A total of 11,343,365 adverse event reports were collected from the first quarter of 2013 to the first quarter of 2021, among which 5,432 cases were identified as ICM-induced HSRs. All the studied ICMs were associated with over-reporting frequencies of HSRs, with iomeprol showing the highest reporting odds ratio (ROR) (ROR = 24.75, 95% confidence interval (CI) = 19.61-31.24). Iopromide (22.29, 20.18-24.62) and ioversol (20.85, 18.54-23.44) were more likely to cause angioedema than other ICMs, particularly in the 45-64 age group. Iomeprol was associated with the largest disproportionality for severe cutaneous adverse reactions (SCARS) (127.90, 103.32-159.88), while iodixanol exhibited maximal incidence when total usage cases were considered. Regarding anaphylactic shock, iopamidol presented the highest disproportionality (31.11, 27.15-35.65), especially in males or seniors aged > 65 years, while iopromide resulted in the maximum frequency in China and the US. CONCLUSION Different ICMs exhibited diverse profiles regarding HSRs, which could be further affected by age, sex or geographical area. Prospective studies are required for patient safety.

Abstract
Background Anaphylactic shock of diclofenac etalhyaluronate agent can be prolonged and recurrent. However, its reports are rare, and consequently, its method of management remains to be established. Case Presentation A 65-year-old woman received an intra-articular injection of diclofenac and hyaluronate. After 20 min, systemic urticaria and severe hypotension developed after walking. After an intramuscular adrenaline injection, she was transferred to our hospital. Despite administration of continuous noradrenaline and adrenaline, hypotension persisted. Seven hours after the joint injection, 25 mL of knee joint fluid was aspirated under ultrasound guidance. Mobilization was performed 24 h after joint injection. However, urticaria rapidly spread after standing. At 45 and 46 h after joint injection, we confirmed that no symptoms, including urticaria, recurred after walking. Conclusion Anaphylactic shock due to intra-articular injection of diclofenac etalhyaluronate is prolonged and requires extended observation. Aspiration of joint fluid may be one of the treatment options.

Abstract
Simple Summary Allergic diseases are presenting a constant increase all over the world and caused by such different substances as food, drugs, and pollens. Anaphylactic shock is the more severe complication of allergy which can induce death if the treatment is not administered immediately. Some patients do not respond to the recommended treatment, intra venous or intramuscular epinephrine. The pathophysiology of anaphylactic shock is still under investigation. The mediators released after the activation of mast cells and basophiles act on endothelial cells and smooth muscle cells, inducing the vasodilation responsible for hypotension and shock. Nitric oxide and hydrogen sulphide are both intracellular mediators that induce vasodilation. The role of potassium voltage dependent channels is suspected. We aimed to demonstrate the ability of a blocker of potassium voltage dependent channels, 4-aminopyridine, alone or in combination with inhibitors of cystathionine γ-lyase to restore blood pressure and improve survival in an ovalbumin rat anaphylactic shock model. The blockade of potassium voltage dependent channels alone or combined with inhibitors of cystathionine γ-lyase, dl-propargylglycine, or β-cyanoalanine restored blood pressure and improved survival. These findings suggest possible investigative treatment pathways for research concerning epinephrine-refractory anaphylactic shock in patients. Abstract The mechanism of anaphylactic shock (AS) remains incompletely understood. The potassium channel blocker 4-aminopyridine (4-AP), the inhibitors of cystathionine γ-lyase (ICSE), dl-propargylglycine (DPG) or β-cyanoalanine (BCA), and the nitric oxide (NO) synthase produce vasoconstriction and could be an alternative for the treatment of AS. The aim of this study was to demonstrate the ability of L-NAME, ICSE alone or in combination with 4-AP to restore blood pressure (BP) and improve survival in ovalbumin (OVA) rats AS. Experimental groups included non-sensitized Wistar rats (n = 6); AS (n = 6); AS (n = 10 per group) treated i.v. with 4-AP (AS+4-AP), epinephrine (AS+EPI), AS+DPG, AS+BCA, or with L-NAME (AS+L-NAME); or AS treated with drug combinations 4-AP+DPG, 4-AP+BCA, 4-AP+L-NAME, or 4-AP+EPI. AS was induced by i.v. OVA (1 mg). Treatments were administered i.v. one minute after AS induction. Mean arterial BP (MAP), heart rate (HR), and survival were monitored for 60 min. Plasma levels of histamine, prostaglandin E2 (PGE2) and F2 (PGF2α), leukotriene B4 and C4, angiotensin II, vasopressin, oxidative stress markers, pH, HCO3, PaO2, PaCO2, and K+ were measured. OVA induced severe hypotension and all AS rats died. Moreover, 4-AP, 4-AP+EPI, or 4-AP+BCA normalized both MAP and HR and increased survival. All sensitized rats treated with 4-AP alone or with 4-AP+BCA survived. The time-integrated MAP “area under the curve” was significantly higher after combined 4-AP treatment with ICSE. Metabolic acidosis was not rescued and NO, ICSE, and Kv inhibitors differentially alter oxidative stress and plasma levels of anaphylactic mediators. The AS-induced reduction of serum angiotensin II levels was prevented by 4-AP treatment alone or in combination with other drugs. Further, 4-AP treatment combined with EPI or with BCA also increased serum PGF2α, whereas only the 4-AP+EPI combination increased serum LTB4. Serum vasopressin and angiotensin II levels were increased by 4-AP treatment alone or in combination with other drugs. Moreover, 4-AP alone and in combination with inhibition of cystathionine γ-lyase or EPI normalizes BP, increases serum vasoconstrictor levels, and improves survival in the Wistar rat model of AS. These findings suggest possible investigative treatment pathways for research into epinephrine-refractory anaphylactic shock in patients.

Abstract
BACKGROUND Anaphylactic shock is the severe state of the allergic reaction, which is rapid in onset and fatal. This is the first study that discusses the anaphylactic shock of exenatide reexposure in the patient who has interrupted exenatide treatment. PATIENT CONCERNS A 47-year-old man was treated with exenatide owing to high blood glucose and obesity. Then he developed localized urticarial on the face, white lip, hands tremble, nausea, vomit, chest stuffiness, dizziness, accompanying with confusion and dyspnea. His blood glucose was 4.6 millimole per liter (mmol/L) and blood pressure was 85/50 millimeters of mercury (mm Hg). DIAGNOSIS Exenatide-induced anaphylactic shock was considered. INTERVENTIONS The emergency electrocardiogram was performed. The patient was treated with dexamethasone sodium phosphate and calcium gluconate, combined with exenatide withdrawal. He also received oral antiallergic agents and intravenous nutrition treatment. OUTCOMES After antishock treatment, the clinical response gradually alleviated. LESSONS Although exenatide is not prone to anaphylaxis, it is the synthetic peptide that can induce antibody formation. Exenatide has immunogenicity with the potential to elicit an allergic reaction upon administration. Clinicians should always pay more attention to the anaphylactic shock of exenatide, when prescribing for diabetics.

Impaired Myocardial Mitochondrial Function in an Experimental Model of Anaphylactic Shock. BIOLOGY 2022; 11:730.

Abstract
Anaphylactic shock (AS) is associated with a profound vasodilation and cardiac dysfunction. The cellular mechanisms underlying AS-related cardiac dysfunction are unknown. We hypothesized that myocardial mitochondrial dysfunction may be associated with AS cardiac dysfunction. In controls and sensitized Brown Norway rats, shock was induced by ovalbumin i.v bolus, and abdominal aortic blood flow (ABF), systemic mean arterial pressure (MAP), and lactatemia were measured for 15 min. Myocardial mitochondrial function was assessed with the evaluation of mitochondrial respiration, oxidative stress production by reactive oxygen species (ROS), reactive nitrogen species (RNS), and the measurement of superoxide dismutases (SODs) activity. Oxidative damage was assessed by lipid peroxidation. The mitochondrial ultrastructure was assessed using transmission electronic microscopy. AS was associated with a dramatic drop in ABF and MAP combined with a severe hyperlactatemia 15 min after shock induction. CI-linked substrate state (197 ± 21 vs. 144 ± 21 pmol/s/mg, p < 0.05), OXPHOS activity by complexes I and II (411 ± 47 vs. 246 ± 33 pmol/s/mg, p < 0.05), and OXPHOS activity through complex II (316 ± 40 vs. 203 ± 28 pmol/s/mg, p < 0.05) were significantly impaired. ROS and RNS production was not significantly increased, but SODs activity was significantly higher in the AS group (11.15 ± 1.02 vs. 15.50 ± 1.40 U/mL/mg protein, p = 0.02). Finally, cardiac lipid peroxidation was significantly increased in the AS group (8.50 ± 0.67 vs. 12.17 ± 1.44 µM/mg protein, p < 0.05). No obvious changes were observed in the mitochondrial ultrastructure between CON and AS groups. Our experimental model of AS results in rapid and deleterious hemodynamic effects and was associated with a myocardial mitochondrial dysfunction with oxidative damage and without mitochondrial ultrastructural injury.

Abstract
Hydatid disease is rare; nevertheless, several areas of the world are endemic. Lebanon is one of the endemic countries. This disease requires careful management, as its diagnosis is tough, and its complications are severe and can lead to sudden death. These complications include fistulas, infection, and rupture. Rupture of a hydatid cyst can mimic acute abdomen and show an array of nonspecific symptoms. It could be mistaken for hemorrhagic shock, trauma, or injury to an intra-abdominal organ. The diagnosis of ruptured hydatid cyst should be kept in mind in cattle-raising countries. We report the case of a polytrauma patient who was suspected to have severe intra-abdominal bleeding and hemorrhagic shock, but imaging and laparotomy showed the rupture of a liver hydatid cyst that drove the patient into anaphylactic shock. This article reviews similar cases in the literature and discusses the diagnostic tools, appropriate management, and expected complications.

Abstract
The effectiveness and safety of drug treatment are the main criteria for its success. Local anesthetics, used in all medical fields, in some cases can cause a wide variety of undesirable side reactions, but in recent years, such manifestations that have arisen in Russian clinical practice tend to qualify as anaphylactic shock. This article presents the types of adverse reactions and global statistics of anaphylaxis to local anesthetics, as well as analyzes the possible reasons for the erroneous diagnosis of fatal outcomes of anaphylaxis. The purpose of the review was to clarify information about reliable markers of clinical and postmortem anaphylaxis, providing unambiguousness and objectivity of forensic medical examination. Attention is focused on the specific postmortem signs of immediate allergic reactions and the sequence of professional interpretation of all the circumstances associated with a fatal adverse reaction against the background of the use of local anesthetics.

Mastocytosis and Mast Cell Activation Disorders: Clearing the Air. Int J Mol Sci 2021; 22:ijms222011270.

Abstract
Mast cells are derived from hematopoietic stem cell precursors and are essential to the genesis and manifestations of the allergic response. Activation of these cells by allergens leads to degranulation and elaboration of inflammatory mediators, responsible for regulating the acute dramatic inflammatory response seen. Mast cells have also been incriminated in such diverse disorders as malignancy, arthritis, coronary artery disease, and osteoporosis. There has been a recent explosion in our understanding of the mast cell and the associated clinical conditions that affect this cell type. Some mast cell disorders are associated with specific genetic mutations (such as the D816V gain-of-function mutation) with resultant clonal disease. Such disorders include cutaneous mastocytosis, systemic mastocytosis (SM), its variants (indolent/ISM, smoldering/SSM, aggressive systemic mastocytosis/ASM) and clonal (or monoclonal) mast cell activation disorders or syndromes (CMCAS/MMAS). Besides clonal mast cell activations disorders/CMCAS (also referred to as monoclonal mast cell activation syndromes/MMAS), mast cell activation can also occur secondary to allergic, inflammatory, or paraneoplastic disease. Some disorders are idiopathic as their molecular pathogenesis and evolution are unclear. A genetic disorder, referred to as hereditary alpha-tryptasemia (HαT) has also been described recently. This condition has been shown to be associated with increased severity of allergic and anaphylactic reactions and may interact variably with primary and secondary mast cell disease, resulting in complex combined disorders. The role of this review is to clarify the classification of mast cell disorders, point to molecular aspects of mast cell signaling, elucidate underlying genetic defects, and provide approaches to targeted therapies that may benefit such patients.

Abstract
OBJECTIVE To describe the clinical features of dogs treated for suspected anaphylaxis in Perth, Western Australia. DESIGN Single-centre observational case series with retrospective and prospective phases. METHODS This was a two-phase study of dogs with clinical suspicion of anaphylaxis presenting to the emergency service of a university teaching hospital. Dogs required evidence of, and appropriate treatment of, a type 1 hypersensitivity reaction as well as two or more organs affected (or cardiovascular signs alone) to be included. Phase 1 includes retrospective case series of 186 dogs (March 2006-December 2018). Phase 2 includes prospective descriptive case series of 46 dogs (October 2017-July 2018) focused on clinical signs. RESULTS In phase 1, 88 (47%) dogs had evidence of insect exposure prior to the acute event. One hundred forty (75%) dogs had dermatological signs, 141 (76%) had gastrointestinal signs and 129 (69%) had cardiovascular signs. Ninety-two (49%) dogs had vasoconstrictive shock (5 with bradycardia), 24 (13%) had vasodilatory shock, 8 (4%) had mixed vasodilatory and vasoconstrictive shock and 5 (3%) had unclassifiable shock. On focused abdominal ultrasound, 42 of 71 (59%) dogs had gallbladder wall oedema and 3 of 71 (4%) dogs had peritoneal free fluid. In phase 2, the distributions of insect exposure, organ dysfunction and sonographic abnormalities were similar to phase 1. CONCLUSION Dogs presenting with suspected anaphylaxis showed a broad range of presentations. Dermatological signs were absent in a proportion of dogs, vasoconstrictive shock was more frequent than vasodilatory and unique features of shock were identified. This study highlights the challenges of diagnosis based on presenting features alone.

Mechanisms Governing Anaphylaxis: Inflammatory Cells, Mediators, Endothelial Gap Junctions and Beyond. Int J Mol Sci 2021; 22:ijms22157785.

Abstract
Anaphylaxis is a severe, acute, life-threatening multisystem allergic reaction resulting from the release of a plethora of mediators from mast cells culminating in serious respiratory, cardiovascular and mucocutaneous manifestations that can be fatal. Medications, foods, latex, exercise, hormones (progesterone), and clonal mast cell disorders may be responsible. More recently, novel syndromes such as delayed reactions to red meat and hereditary alpha tryptasemia have been described. Anaphylaxis manifests as sudden onset urticaria, pruritus, flushing, erythema, angioedema (lips, tongue, airways, periphery), myocardial dysfunction (hypovolemia, distributive or mixed shock and arrhythmias), rhinitis, wheezing and stridor. Vomiting, diarrhea, scrotal edema, uterine cramps, vaginal bleeding, urinary incontinence, dizziness, seizures, confusion, and syncope may occur. The traditional (or classical) pathway is mediated via T cells, Th2 cytokines (such as IL-4 and 5), B cell production of IgE and subsequent crosslinking of the high affinity IgE receptor (FcεRI) on mast cells and basophils by IgE-antigen complexes, culminating in mast cell and basophil degranulation. Degranulation results in the release of preformed mediators (histamine, heparin, tryptase, chymase, carboxypeptidase, cathepsin G and tumor necrosis factor alpha (TNF-α), and of de novo synthesized ones such as lipid mediators (cysteinyl leukotrienes), platelet activating factor (PAF), cytokines and growth factors such as vascular endothelial growth factor (VEGF). Of these, histamine, tryptase, cathepsin G, TNF-α, LTC4, PAF and VEGF can increase vascular permeability. Recent data suggest that mast cell-derived histamine and PAF can activate nitric oxide production from endothelium and set into motion a signaling cascade that leads to dilatation of blood vessels and dysfunction of the endothelial barrier. The latter, characterized by the opening of adherens junctions, leads to increased capillary permeability and fluid extravasation. These changes contribute to airway edema, hypovolemia, and distributive shock, with potentially fatal consequences. In this review, besides mechanisms (endotypes) underlying IgE-mediated anaphylaxis, we also provide a brief overview of IgG-, complement-, contact system-, cytokine- and mast cell-mediated reactions that can result in phenotypes resembling IgE-mediated anaphylaxis. Such classifications can lead the way to precision medicine approaches to the management of this complex disease.

Abstract
Abstract Anaphylaxis is defined as a rapid systemic reaction that develops in individuals previously exposed to specific allergens. The new exposure causes systemic cellular degranulation, which in turn leads to cardiovascular and respiratory changes that are fatal if not treated immediately. One of the main problems of this scenario in the forensic field is the determination of a correct post-mortem diagnosis. Traditional methods, such as histopathological examination of the respiratory tract and the use of specific antibodies used in immunohistochemistry, are sensitive but not always specific and therefore do not guarantee a high degree of probability in the diagnosis of anaphylaxis. For this reason, a new and promising research frontier in this field of forensic pathology could be represented by the application of miRNAs as biomarkers, as has been done in other areas of medicine.

Abstract
A 70-year-old man was admitted to our hospital due to "liver cirrhosis; grade 3 hypertension; pulmonary infection". On May 27, 2019, during upper abdomen plain and enhanced magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP), the patient experienced anaphylactic shock, manifested as sudden unconsciousness and lack of response, after intravenous administration of gadobenate dimeglumine (Multihance®). Gadobenate dimeglumine is a paramagnetic contrast used during diagnostic MRI. It has hepatobiliary specificity with very good imaging performance. A small amount is absorbed by normal liver cells after intravenous injection and excreted via the bile ducts while maintaining the chemical structure of gadobenate dimeglumine. It allows the visualization of local angiogenesis and perfusion, which reflect the hepatic blood supply and recent liver function, thereby providing a reference for clinical diagnosis. Gadobenate dimeglumine intravenous injection may cause adverse reactions such as nausea, dizziness, and anaphylactic shock. Anaphylactic shock is a known serious adverse reaction of gadobenate dimeglumine injection. In this paper, we report a case of gadobenate dimeglumine-induced anaphylactic shock based on the temporal relationship between the onset of symptoms and the injection. The patient received chest compressions and balloon-assisted ventilation in addition to rehydration and volume expansion and vasoactive drugs to maintain blood pressure, etc. The patient died despite treatments. In the clinical, physicians, nurses, and clinical pharmacists should closely monitor patients and promptly discontinue drug administration and provide symptomatic care in case of adverse reactions.

Abstract
INTRODUCTION The SARS-CoV-2 pandemic has taken a heavy toll of 4 million deaths. We were all looking forward to the authorisation of safe vaccines. Soon after vaccination programmes started, the reports about anaphylaxis began to emerge. Growing anxiety has urged regulatory agencies and academic societies to issue adequate recommendations regarding patient eligibility to vaccination. AIM OF THE STUDY Observation of patients who had a history of a severe anaphylactic reaction and/or anaphylactic shock and were vaccinated against COVID-19. MATERIAL AND METHODS A single-centre, prospective, observational study was conducted at the Department of Infectious Diseases and Paediatrics at Stefan Żeromski Specialist Hospital in Krakow, Poland. Adult patients with a history of a severe anaphylactic reaction and/or anaphylactic shock and patients without it were administered the Comirnaty vaccine by Pfizer-BioNTech or the ChAdOx1-S vaccine by AstraZeneca in a two-dose schedule at the department. The patients were then observed at the department for 60 minutes. A week after each vaccination dose, the patients were contacted by telephone in order to collect data about a late allergic reaction. RESULTS In total, 403 patients were enrolled. For the Pfizer BioNTech Comirnaty vaccine, the study group (i.e. patients with a history of severe anaphylactic reactions to various substances, other than those present in the vaccine) included 151 patients, and there were 161 controls. For the AstraZeneca ChAdOx1-S vaccine, the study group included 47 patients, and 44 patients formed the control group. Nine cases of severe anaphylactic reactions were reported: 3 in the study groups (1.5%) and 6 in the control groups (3%). Anaphylactic shock after vaccine administration occurred in one patient from the control group. CONCLUSIONS COVID-19 vaccination with using Pfizer-BioNTech Comirnaty and AstraZeneca ChAdOx1-S is safe also for patients with a history of a severe anaphylactic reaction and/or anaphylactic shock. Severe anaphylactic reactions and anaphylactic shock, although rare, may also develop in patients without a prior history of allergic conditions. The Personnel od vaccination centres should be therefore trained to provide medical help. Incorrect patient exclusions delay the attainment of the goal determined for the vaccination programme.

Abstract
Intravenous injection of nanopharmaceuticals can induce severe hypersensitivity reactions (HSRs) resulting in anaphylactoid shock in a small percentage of patients, a phenomenon explicitly reproducible in pigs. However, there is a debate in the literature on whether the pig model of HSRs can be used as a safety test for the prediction of severe adverse reactions in humans. Given the importance of using appropriate animal models for toxicity/safety testing, the choice of the right species and model is a critical decision. In order to facilitate the decision process and to expand the relevant information regarding the pig or no pig dilemma, this review examines an ill-fated clinical development program conducted by Baxter Corporation in the United States 24 years ago, when HemeAssist, an αα (diaspirin) crosslinked hemoglobin-based O2 carrier (HBOC) was tested in trauma patients. The study showed increased mortality in the treatment group relative to controls and had to be stopped. This disappointing result had far-reaching consequences and contributed to the setback in blood substitute research ever since. Importantly, the increased mortality of trauma patients was predicted in pig experiments conducted by US Army scientists, yet they were considered irrelevant to humans. Here we draw attention to that the underlying cause of hemoglobin-induced aggravation of hemorrhagic shock and severe HSRs have a common pathomechanism: cardiovascular distress due to vasoconstrictive effects of hemoglobin (Hb) and reactogenic nanomedicines, manifested, among others, in pulmonary hypertension. The main difference is that in the case of Hb this effect is due to NO-binding, while nanomedicines can trigger the release of proinflammatory mediators. Because of the higher sensitivity of cloven-hoof animals to this kind of cardiopulmonary distress compared to rodents, these reactions can be better reproduced in pigs than in murine or rat models. When deciding on the battery of tests and the appropriate models to identify the potential hazard for nanomedicine-induced severe HSR, the pros and cons of the various species must be considered carefully.

Abstract
Anaphylaxis secondary to thymoglobulin (anti-thymocyte globulin) is a rare condition that can be life threatening. Thymoglobulin is a rabbit-derived T-cell depleting polyclonal immunoglobulin. It is commonly used for induction immunosuppression and/or for treatment of acute rejection in renal transplantation. We report a case of a living kidney transplant recipient who developed intraoperative anaphylactic shock secondary to thymoglobulin. The patient had a history of pet rabbit exposure. This case report highlights the importance of prompt identification and management of intraoperative anaphylaxis, which is key to a successful outcome. Induction immunosuppression selection based on patient characteristics is important. Communication between the anesthesia team and surgeons played a key role in stopping the donor surgery.

[PMID: 32650469 PMCID: PMC7399996 DOI: 10.3390/ijerph17144921] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 07/02/2020] [Accepted: 07/03/2020] [Indexed: 12/23/2022]
Abstract
Allergic disorders in the agriculture sector are very common among farm workers, causing many injuries and occupational diseases every year. Agricultural employees are exposed to multiple conditions and various allergenic substances, which could be related to onset of anaphylactic reactions. This systematic review highlights the main clinical manifestation, the allergens that are mostly involved and the main activities that are usually involved. This research includes articles published on the major databases (PubMed, Cochrane Library, Scopus), using a combination of keywords. The online search yielded 489 references; after selection, by the authors, 36 articles (nine reviews and 27 original articles) were analyzed. From this analysis, the main clinical problems that were diagnosed in this category were respiratory (ranging from rhinitis to asthma) and dermatological (eczema, dermatitis, hives) in nature, with a wide symptomatology (from a simple local reaction to anaphylaxis). The main activities associated with these allergic conditions are harvesting or cultivation of fruit and cereals, beekeepers and people working in greenhouses. Finally, in addition to the allergens already known, new ones have emerged, including triticale, wine, spider and biological dust. For these reasons, in the agricultural sector, research needs to be amplified, considering new sectors, new technologies and new products, and ensuring a system of prevention to reduce this risk.

Cephalosporins' Cross-Reactivity and the High Degree of Required Knowledge. Case Report and Review of the Literature. Antibiotics (Basel) 2020; 9:antibiotics9050209. [PMID: 32344946 PMCID: PMC7277108 DOI: 10.3390/antibiotics9050209] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 04/14/2020] [Accepted: 04/23/2020] [Indexed: 12/30/2022] Open
Abstract
Antibiotic cross-reactivity represents a phenomenon of considerable interest as well as antibiotic resistance. Immediate reactions to cephalosporins are reported in the literature with a prevalence of only 1%-3% of the population, while anaphylactic reactions are rarely described (approximately 0.0001%-0.1%) as well as fatalities. Allergic reaction to cephalosporins may occur because of sensitization to unique cephalosporin haptens or to determinants shared with penicillins. Cross-reactivity between cephalosporins represents, in fact, a well-known threatening event involving cephalosporins with similar or identical R1- or R2-side chains. The present report describes the case of a 79-year-old man who suddenly died after intramuscular administration of ceftriaxone. Serum dosage of mast cell tryptase from a femoral blood sample at 3 and 24 hours detected values of 87.7μg/L and 93.5μg/L, respectively (cut-off value 44.3 μg/L); the serum-specific IgE for penicillins, amoxicillin, cephaclor and also for the most common allergens were also determined. A complete post-mortem examination was performed, including gross, histological and immunohistochemical examination, with an anti-tryptase antibody. The cause of death was identified as anaphylactic shock: past administrations of cefepime sensitized the subject to cephalosporins and a fatal cross-reactivity of ceftriaxone with cefepime occurred due to the identical seven-position side chain structure in both molecules. The reported case offers food for thought regarding the study of cross-reactivity and the need to clarify the predictability and preventability of the phenomenon in fatal events.

Abstract
OBJECTIVE We aim to examine the characteristics of the symptoms induced by exercise provocation tests following allergen consumption in patients who have undergone oral immunotherapy (OIT). METHOD Patients who were positive for exercise provocation tests in Miyagi Children's Hospital from April 2012 to January 2019 were retrospectively analyzed. Patients were classified into food-dependent exerciseinduced anaphylaxis (FDEIA) group and post-OIT-FDEIA group. RESULT Six patients in the FDEIA group and 19 patients in the post-OIT-FDEIA group were analyzed. There were no significant differences in age, sex, and number of complications between the FDEIA and post-OIT-FDEIA groups, except for level of total serum immunoglobulin E. The median time from the start of exercise to onset of symptoms was 20 min in the FDEIA group and 25 min in the post-OIT-FDEIA group. The rate of adrenaline administration in post-OIT-FDEIA group was significantly lower. The median time from exercise to onset of severe symptoms requiring adrenaline was 32.5 min in the FDEIA group and 25 min in the post-OIT-FDEIA group. CONCLUSION These data suggest that FDEIA and post-OIT-FDEIA patients can exhibit similar clinical symptoms, and all symptoms occurred in 60 minutes after exercise.

Abstract
The term allergic angina, introduced for the first time by Nicholas Kounis in 1991, initially referred to the coexistence of acute coronary syndromes with allergy or hypersensitivity. At present, it is believed that Kounis syndrome is a particular case of systemic disease, with multiorgan arterial involvement generated during immediate hypersensitivity reactions. Myocardial bridging (MB), a condition that can induce coronary artery spasm, has long been regarded as a benign condition. Since both pathologies are associated with arterial spasm, Kounis syndrome and MB are considered to be confounding pathologies for acute coronary syndromes, and their association is quite a rare finding. To date, there are no precise data on the epidemiology, and the population affected by Kounis syndrome seems to be highly heterogeneous. Since this is a rare disease, even less is known about possible different phenotypes, including MB overlap. We report a case of type I variant Kounis syndrome associated with MB with no evidence of coronary artery disease, occurring as late presentation, following a severe systemic reaction (anaphylaxis) induced by a Hymenoptera sting. At present, only two other cases of type I and one case of type II Kounis syndrome occurring in patients with myocardial bridging have been described.

Abstract
A 66-year-old patient with aortic stenosis was scheduled for an aortic valve replacement and coronary artery bypass surgery. Anesthesia was induced by intravenous injection of midazolam, fentanyl, and propofol. After administration of rocuronium, he developed anaphylactic shock, which was diagnosed by clinical signs, vital parameters, and unresponsiveness to the usual vasopressors. After 30 min of cardiopulmonary resuscitation, the patient survived without any neurological deficits. This case is a reminder that early recognition and treatment of intraoperative hypersensitivity reactions are imperative. Anesthetists should also receive simulation training to achieve an adequate experience in a safe environment. With a well-trained team, it is possible to save the life of patients with aortic stenosis.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most prescribed medications globally. They act through inhibiting cyclooxygenase (COX)-1 and COX-2 enzymes. In contrast to other NSAIDs, anaphylaxis due to ibuprofen is quite rare, especially in adults. The management of anaphylaxis depends on early recognition of the symptoms, administering epinephrine, and avoidance of the causing allergen. Here, we report a case of a 23-year-old female who presented with anaphylactic shock after ingesting ibuprofen.

Recurrent anaphylaxis in the United States: time of onset and risk factors. Int Forum Allergy Rhinol 2019; 10:320-327. [PMID: 31774625 DOI: 10.1002/alr.22502] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 11/06/2019] [Accepted: 11/08/2019] [Indexed: 01/06/2023]
Abstract
BACKGROUND Studies have not yet examined the trends and risk factors of biphasic and recurrent anaphylaxis in the United States using International Classification of Diseases, tenth revision (ICD-10) CM codes. The goal of this study is to examine the trends of biphasic and recurrent anaphylaxis in all patient care settings (inpatient, outpatient, emergency department, and observation). METHODS We used the Clinformatics database from 2015 to 2017. Our main outcome measure was recurrent anaphylactic events occurring within 1 year after the initial event. We used Cox proportional hazards modeling to assess the factors associated with recurrent anaphylaxis and the Kaplan-Meier method to estimate time to recurrence. RESULTS There were a total of 19,039 patients with incident anaphylaxis in 2016 and, of these, 2017 had a recurrent anaphylaxis event in the 12-month period after the index date (10.6%). The most common trigger for recurrent anaphylaxis is venom followed by food allergens. Pediatric patients aged <18 years were more likely to develop recurrent anaphylaxis compared with patients aged 18 to 64 years (hazard ratio [HR], 1.53). Patients with allergic rhinitis and asthma were more likely to develop recurrent anaphylaxis compared to those without these comorbidities (HR, 1.15 and 1.27, respectively). CONCLUSION This is the first national study using ICD-10 CM codes looking at rates of biphasic and recurrent anaphylaxis in all patient care settings. Recurrent anaphylaxis is more common in the first 3 days after the initial event, in younger patients (<18 years), and in patients with allergic rhinitis and/or asthma. Physicians need to prescribe epinephrine auto-injectors and educate their patients about the risk of recurrence.

Abstract
A 10-year-old male castrated Maltese was referred with clinical signs of hematuria, stranguria, and pollakiuria. The dog was diagnosed with sterile hemorrhagic cystitis with urethroliths and cystoliths. To remove the uroliths, the dog underwent retrograde urohydropropulsion followed by a cystotomy. The following day, persistent bleeding in the urinary bladder was identified with large hematoma, hematuria and anemia. In order to reduce bleeding, the dog received 10 mg/kg of tranexamic acid (TXA) intravenously. Immediately after TXA administration, the dog developed anaphylactic shock manifested by hypotension, hypothermia, tachycardia and a dull mentation. Thus, an emergency treatment including bolus injection of crystalloid, administration of dexamethasone and diphenhydramine, and oxygen supplementation was given, after which the dog quickly recovered within a few minutes.

Abstract
Systemic anaphylaxis is a life-threatening and allergic reaction that affects various organs. We previously reported that, in the stomach, gastric vasoconstriction occurring at the late phase (15-55 min after injection of ovalbumin antigen) was observed in anesthetized rats sensitized with ovalbumin. In addition, anaphylaxis enhances gastric motility and delays emptying. However, the role of extrinsic autonomic nervous system on antigen-induced gastric alterations was not known. Thus, using the same rat anaphylaxis model, we aimed to determine the changes in the efferent and afferent autonomic nerve activities in the stomach during anaphylactic hypotension. The findings showed that injection of ovalbumin antigen caused substantial systemic hypotension in all sensitized rats. The efferent gastric sympathetic nerve activity (ef-GSNA), but not the efferent vagal nerve activity, increased only at the early phase (1-10 min after injection of ovalbumin antigen) and showed baroreceptor reflex, as evidenced by a stimulatory response to sodium nitroprusside-induced hypotension. In general, excitation of ef-GSNA could induce pylorus sphincter contraction and gastric vasoconstriction. In the present study, we found that sympathectomy attenuated the anaphylaxis-induced decrease in gastric flux but not the increase in gastric vascular resistance. Thus, the increase in ef-GSNA may cause anaphylactic pylorus sphincter contraction but not anaphylactic gastric vasoconstriction. On the other hand, the afferent gastric vagal nerve activity, but not the afferent sympathetic nerve activity, increased during the early phase of anaphylactic hypotension. However, vagotomy produced no effects on the anaphylactic gastric dysfunction. In conclusion, the gastric sympathetic nerves partly modulate stomach function during systemic anaphylaxis.

Abstract
One Case for Two Abstract. We report on a 59-year-old patient with a rash, hypotension and chest pain after eating tuna fish. A diagnosis of scombroid fish poisoning was made. It is a syndrome resembling an allergic reaction that occurs after eating fish of the Scombridae family contaminated with high levels of histamine. The authorities responsible for food safety should be immediately informed in order to investigate the event from their perspective, i.e. inspect selling premises, sample and test implicated food, as well as to take appropriate measures. Anaphylaxis rarely manifests as a vasospastic acute coronary syndrome, called Kounis syndrome.

Abstract
Intraoperative search for the sentinal node using patent blue is considered a non risk procedure. We emphasize the highly exceptional nature of this adverse effect previously observed in other disciplines using this coloring agent. We present a case of allergic reaction to patent blue in a patient who underwent left mastectomy with sentinel lymph node. About 25 min after the dye injection, the patient developed increased heart frequency and allergic skin reaction. The patient was treated successfully with decreased inspired fraction of inhaled anesthetic and fluid replacement. The patient recovered uneventfully and was discharged from the PACU 3h after the end of surgery without skin changes and was discharged from hospital on the morning after surgery. Allergic reactions with the use of patent blue are far superior to the hypersensitivity reactions seen with anesthetic and adjuvant drugs. Therefore, the anesthesiologist must be aware of cardiovascular instability associated with skin changes during the use of patent blue, for early diagnosis and appropriate treatment of this hypersensitivity reaction to this dye. Skin tests done later confirmed allergy to patent blue dye; the tests induced a small syndrome reaction. Surgical personnel who use patent blue dye should be made aware of the risk of allergic reactions, sometimes severe, to this dye.

Abstract
The first reported human anaphylactic death is considered to be the Pharaoh Menes death, caused by a wasp sting. Currently, anaphylactic cardiovascular events represent one of most frequent medical emergencies. Rapid diagnosis, prompt and appropriate treatment can be life saving. The main concept beyond anaphylaxis lies to myocardial damage and ventricular dysfunction, thus resulting in cardiovascular collapse. Cardiac output depression due to coronary hypoperfusion from systemic vasodilation, leakage of plasma and volume loss due to increased vascular permeability, as well as reduced venous return, are regarded as the main causes of cardiovascular collapse. Clinical reports and experiments indicate that the human heart, in general, and the coronary arteries, in particular, could be the primary target of the released anaphylactic mediators. Coronary vasoconstriction and thrombosis induced by the released mediators namely histamine, chymase, tryptase, cathepsin D, leukotrienes, thromboxane and platelet activating factor (PAF) can result to further myocardial damage and anaphylaxis associated acute coronary syndrome, the so-called Kounis syndrome. Kounis syndrome with increase of cardiac troponin and other cardiac biomarkers, can progress to heart failure and cardiovascular collapse. In experimental anaphylaxis, cardiac reactions caused by the intracardiac histamine and release of other anaphylactic mediators are followed by secondary cardiovascular reactions, such as cardiac arrhythmias, atrioventricular block, acute myocardial ischemia, decrease in coronary blood flow and cardiac output, cerebral blood flow, left ventricular developed pressure (LVdp/dtmax) as well as increase in portal venous and coronary vascular resistance denoting vascular spasm. Clinically, some patients with anaphylactic myocardial infarction respond satisfactorily to appropriate interventional and medical therapy, while anti-allergic treatment with antihistamines, corticosteroids and fluid replacement might be ineffective. Therefore, differentiating the decrease of cardiac output due to myocardial tissue hypoperfusion from systemic vasodilation and leakage of plasma, from myocardial tissue due to coronary vasoconstriction and thrombosis might be challenging during anaphylactic cardiac collapse. Combined antiallergic, anti-ischemic and antithrombotic treatment seems currently beneficial. Simultaneous measurements of peripheral arterial resistance and coronary blood flow with newer diagnostic techniques including cardiac magnetic resonance imaging (MRI) and myocardial scintigraphy may help elucidating the pathophysiology of anaphylactic cardiovascular collapse, thus rendering treatment more rapid and effective.

Abstract
RATIONALE Life-threatening anaphylactic shock is a rare (1 in 1 million) but documented occurrence in response to subcutaneous immunotherapy. Immediate administration of Epinephrine (Epi) is critical to save lives in these situations. The current protocol for systemic reactions in immunotherapy is for the prescribing physician to reassess the dosing and schedule as well as the risk:benefit assessment for the therapy and determine whether or not to proceed. PATIENT CONCERNS The patient revealed concerns regarding the neurologic sequela sustained after undergoinig life-threatening anaphylactic shock. DIAGNOSIS The patient was diagnosed with anaphylactic shock and treated appropriately. INTERVENTIONS The patient experienced shortness of breath and was promptly administered 2 shots of 0.3mg Epi followed by a loss of consciousness (LOC) and a series of 4 consecutive seizures accompanied with LOC and urinary incontinence. Seizures as a manifestation of anaphylaxis are rare with 1 study claiming 13% of cases of anaphylaxis having LOC and only 1.5% cases with loss of bladder or bowel control. OUTCOMES This case is one of continued subcutaneous immunotherapy after the patient had an initial systemic reaction suspicious for anaphylaxis 6 months before the life-threatening anaphylaxis, both induced by immunotherapy. In both instances, there was a significant amount of neurologic involvement. Neurologic sequela included a transient tremor and permanent deficits in vision, fine motor coordination evidenced by a change in handwriting. LESSONS The current protocol was followed in this patient but still ended up almost ending her life. This protocol seems to be inadequate with regards to potential fatality. Even though a very small number, some patients face life-threatening adverse effects after apparently very low-risk immunotherapies. Therefore, reevaluating the treatment protocol with addition of a longer post-shot observation step and discontinuing treatment in the case of adverse events may help minimize the overall risk of any fatal outcome.

Abstract
Steroid pulse therapy with methylprednisolone (mPSL) succinate ester is the most common treatment for neuromyelitis optica (NMO); no cases of anaphylaxis have been reported to date. Here, we report two cases of anaphylactic shock induced by mPSL pulse therapy in patients with NMO and concurrent systemic lupus erythematosus. Both patients had received several courses of mPSL pulse therapy without any problems previously. Repeated mPSL pulse therapy and comorbid humoral autoimmune disease might increase the risk of anaphylaxis. Corticosteroids without succinate esters should be considered as an alternative therapy to prevent anaphylaxis.

Abstract
Slow lorises (Nycticebus spp.) are one of six venomous mammals, and the only known venomous primate. In the wild envenomation occurs mainly during conspecific competition for mates and territory, but may also be used as an application against parasites or for predator defense. Envenomation in humans is documented, with the most extreme accounts detailing near-fatal anaphylactic shock. From September 2016 - August 2017, we received questionnaire responses from 80 wild animal practitioners working with Nycticebus spp. in zoos, rescue centres and in the wild. We identified 54 practitioners who had experience of being bitten or were otherwise affected by slow loris venom, and an additional 26 incomplete entries. No fatalities were reported. Fifteen respondents noted that medical intervention was required, 12 respondents indicated no reaction to being bitten (9 of these indicated they were wearing gloves). Symptoms for those affected included: anaphylactic shock, paraesthesia, haematuria, dyspnoea, extreme pain, infection and general malaise. Impact of slow loris bites ranged from instantaneous to long-persisting complications, and healing time ranged from 1 day to >8 months. Extremities, including hands and arms, were mostly affected from the bites. Six of nine species of slow loris were reported to bite, with N. pygmaeus being the most common in our sample. We make suggestions regarding the use of these highly threatened yet dangerous primates as unsuitable tourist photo props and zoo animal ambassadors. We discuss the medical complications experienced in relation to protein sensitisation, and bacterial pathogenesis. We recommend future work to ascertain the protein content of slow loris venom to aid in enabling mitigation of risks posed.

Abstract
During general anesthesia, while muscle relaxants, latex and antibiotics are normally considered as very common causes of anaphylactic reactions, there are no documented cases of anaphylaxis due to inhalational agents. We report the case of a 6-year-old child scheduled for adenotonsillectomy who had an anaphylactic shock reaction due to Sevoflurane. Several allergic tests were performed to detect the trigger. Drugs used during operation were tested on both patient and three matched controls. While controls were negative, the patient displayed a positive reaction to Sevoflurane. To our knowledge, this is the first published report describing an allergic reaction caused by a volatile anesthetic.

Abstract
Although glucocorticoids are often used as an adjunct to epinephrine to treat anaphylactic shock, glucocorticoids can also be a rare cause of anaphylactic shock. Only through the administration of a challenge dose of different glucocorticoids and different substrates that glucocorticoids are delivered in can the determination be made about which glucocorticoid or accompanying solvent may be the culprit which caused the anaphylactic reaction. These challenge tests should only be performed in a controlled environment as repeat anaphylaxis is a risk, especially if the patient has a history of glucocorticoid-induced anaphylaxis.
