Nsaids crossed hypersensitivity

Fixed drug eruption (FDE) is a well-recognized, non-immediate, drug hypersensitivity reaction, often attributed to the use of various medications, most commonly non-steroidal anti-inflammatory drugs (NSAIDs) and antibiotics. Cross-reactivity between related NSAIDs in FDE has been reported, but among chemically unrelated NSAIDs, is rare. Herein, we present a rare well-documented case where a patient initially displayed tolerance to etoricoxib after experiencing a nimesulide-induced FDE. Subsequently, the patient developed an etoricoxib-induced FDE, accompanied by the development of bullous lesions...

Perioperative hypersensitivity reactions vary from mild to potentially fatal anaphylaxis, resulting in significant morbidity and mortality. Most of the perioperative hypersensitivity and allergic reactions are attributed to antibiotics, antiseptic solutions, latex, and opioids. In the current thrust for opioid-free anesthesia, owing to its multiple advantages, paracetamol and nonsteroidal antiinflammatory agents play a significant role in multi-modal pain and inflammatory response management. Nearly nine out of ten individuals experience postoperative pain, one-third experience postoperative nausea and vomiting, and one-fourth experience fever, irrespective of surgery and type of anesthesia, often as an inflammatory response...

BACKGROUND: IgA vasculitis and hypersensitivity reactions following exposure to non-steroidal anti-inflammatory drugs (NSAIDs) are very rarely associated with purpura fulminans (PF). The latter is a coagulation event characterised by decreased levels of protein C and a rapidly progressive purpuric rash, often leading to ischaemia, amputations and death. CASE SUMMARY: A previously healthy 66-year-old man presented with a vasculitic rash and abdominal pain following exposure to naproxen (NSAID), which quickly deteriorated to purpura fulminans-like eruption and skin necrosis, mainly involving the face and hands...

BACKGROUND: Hypersensitivity reactions to non-steroidal anti-inflammatory drugs (HR-NSAIDs) are common adverse events related to the widespread use of over-the-counter NSAIDs for the treatment of a variety of inflammatory conditions. Urticaria is the most commonly reported immediate cutaneous clinical sign of HR-NSAIDs, but it can be a manifestation of pathophysiologically different clinical entities that require different therapeutic strategies. The aim of this study is to ease the identification of the correct phenotype of HR-NSAIDs in patients reporting urticaria associated with the intake of NSAIDs and provide updated information about their diagnosis and management...

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most commonly used classes of medications, and are among the leading causes of drug hypersensitivity. NSAIDs hypersensitivity reactions are classified by symptom involvement and NSAIDs subclass cross-reactivity. Reactions varying from cutaneous involvement to respiratory symptoms can be triggered by multiple NSAIDs subclasses. Anaphylaxis, while rare, can be induced by a single NSAID, with tolerability of other structurally unrelated subclasses...

BACKGROUND: Ibuprofen and other arylpropionic acid derivatives (APs) are among the most consumed non-steroidal anti-inflammatory drugs (NSAIDs) worldwide at all age ranges; however, little is known about drug hypersensitivity reactions (DHRs) they induce. OBJECTIVE: Our aim was to characterize in detail patients reporting DHRs to APs. METHODS: We prospectively evaluated patients with symptoms suggestive of AP-DHRs and analyzed their clinical characteristics, reported reactions, and diagnostic approaches...

BACKGROUND: Exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (IBU) and naproxen (NAP) is associated with idiosyncratic drug-induced liver injury (DILI). Carboxylate bioactivation into reactive metabolites (e.g., acyl glucuronides, AG) and resulting T-cell activation is hypothesized as causal for this adverse event. However, conclusive evidence supporting this is lacking. METHODS: In this work, we identify CD4+ and CD8+ T-cell hepatic infiltration in a biopsy from an IBU DILI patient...

PURPOSE: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a predominantly type 2 inflammatory disease with a high symptom burden. Data are lacking on the comparative health status of patients with CRSwNP. This analysis compared baseline physical and mental health-related quality of life (HRQoL) and overall health status of patients with severe CRSwNP enrolled in a Phase 3 clinical trial with general population norms and with other chronic diseases. METHODS: In this post hoc cross-sectional analysis of baseline data from the SINUS-24 study (NCT02912468), HRQoL was measured using the 36-item Short Form (SF-36) questionnaire and general health status was measured using the EuroQol-5 Dimension visual analog scale (EQ-VAS)...

BACKGROUND: There are hypersensitivity reactions (HRs) to foods in which nonsteroidal anti-inflammatory drugs (NSAIDs) act as aggravating factors (NSAID-exacerbated food allergy, NEFA) or cofactors (NSAID-induced food allergy, NIFA), often misdiagnosed as HRs to NSAIDs. Urticarial/angioedematous and/or anaphylactic reactions to ≥ 2 chemically unrelated NSAIDs do not meet the current classification criteria. However, they may be considered as part of a cross-reactive type of acute HR, which is NSAID-induced urticaria/angioedema with/without respiratory and/or systemic symptoms of anaphylaxis (NIUAA)...

BACKGROUND: Patients widely use medical identification (ID) to indicate their food and drug allergies, and chronic medical conditions. One chronic condition for which patients are recommended to use a form of medical ID is Aspirin-Exacerbated Respiratory Disease (AERD), a disease characterized by the presence of asthma, chronic rhinosinusitis with nasal polyps and sensitivity to aspirin and other COX-1 inhibitors, including nonsteroidal anti-inflammatory drugs (NSAIDs). The uptake of medical ID use in AERD is unknown and has not been widely studied in this population...

Dear Editor, Photoallergic reactions are classic T-cell-mediated or delayed-type hypersensitivity reactions of the skin in response to a photoallergen (or a cross-reacting chemical) to which a subject was sensitized in the past (1). The immune system recognizes the changes caused by ultraviolet (UV) radiation; it produces antibodies and causes inflammation of the skin in the exposed areas (2). Common photoallergic drugs and ingredients are included in some sunscreens, aftershave lotions, antimicrobials (especially sulfonamides), non-steroidal anti-inflammatory drugs (NSAIDs), diuretics, anticonvulsants, chemotherapy drugs, fragrances, and other hygiene products (1,3,4)...

The use of acetylsalicylic acid (ASA) is problematic in subjects with histories of hypersensitivity reactions (HRs) to it or with cross-reactive types of nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity. We sought to evaluate the efficacy of low-dose ASA challenge (LDAC) and desensitization to allow ASA therapy at an antiplatelet dose in patients with atherosclerotic cardiovascular disease (ASCVD) or multiple related risk factors and histories of HRs to ASA or ≥ 2 chemically unrelated NSAIDs...

PURPOSE OF REVIEW: To provide a review of available literature regarding nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity with an emphasis on more recent findings. RECENT FINDINGS: Oral provocation tests with aspirin are important for diagnosis and management in adult and pediatric populations with reported NSAID hypersensitivity. Risk of cross-reactivity to COX-2 inhibitors varies by NSAID hypersensitivity phenotype. COX-2 inhibitors are tolerated in aspirin-exacerbated respiratory disease...

Drug hypersensitivity reactions (DHRs) are a type of adverse drug reactions with heterogeneous pathophysiological mechanisms and a broad spectrum of clinical manifestations. Since over-diagnosing is common in children, a complete allergy work-up is needed. A cross-sectional study was conducted at a tertiary care institution, covering the five-year period. Five hundred and four patients of both sexes, mean age 7.5 and with a medical history suggestive of DHR were evaluated. ENDA/EAACI guidelines were used for a diagnostic algorithm...

Immediate hypersensitivity reactions can pose a clinical and diagnostic challenge, mainly because of the multifarious clinical presentation and distinct underlying - frequently uncertain - mechanisms. Anaphylaxis encompasses all rapidly developing and life-threatening signs and may cause death. Evidence has accumulated that immediate hypersensitivity and anaphylaxis do not necessarily involve an allergen-specific immune response with cross-linking of specific IgE (sIgE) antibodies bound to their high-affinity IgE receptor (FcεRI) on the surface of mast cells (MCs) and basophils...

INTRODUCTION: Ibuprofen is the most common culprit drug causing nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity in children. We aimed to evaluate the frequency, clinical characteristics, and risk factors of confirmed ibuprofen allergy in children presenting with a history of suspected immediate type ibuprofen-induced hypersensitivity reactions. METHODS: We evaluated 50 (35 M, 15 F) children with a median age of 7 years, who were referred to our clinic with suspected immediate ibuprofen hypersensitivity...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) may exacerbate respiratory symptoms. A recent European Academy of Allergy and Clinical Immunology position paper recommended the use of an acronym, N-ERD (NSAID-exacerbated respiratory disease), for this hypersensitivity associated with asthma or chronic rhinosinusitis with or without nasal polyposis. Our aim was to estimate the prevalence of N-ERD and identify factors associated with N-ERD. METHODS: In 2016, a cross-sectional questionnaire survey of a random adult population of 16 000 subjects aged 20-69 years was performed in Helsinki and Western Finland...

INTRODUCTION: Multiple drug hypersensitivity (MDHS) is defined as confirmed drug hypersensitivity (DHS) to 2 or more drugs that are not chemically related. The objective of our study is to describe the cases of MDHS with antibiotics notified to the regional pharmacovigilance service (SRPV) of Sfax (Tunisia). METHODS: Our study is of a descriptive cross-sectional type, focusing on patients who consulted at the SRPV in Sfax during the period between 2013 and 2020 and who presented at least two episodes of DHS occurring at different times (at least one month apart)...

INTRODUCTION: Wheat is the most important cereal for human nutrition but its high consumption is associated to an increasing complaint of wheat-related disorders, many of which are allergic in nature and different in respect to the involved allergens. In this study, we compared the clinical aspects of wheat allergy presented by patients sensitized to Tri a 19 in respect to those presented by patients sensitized to Tri a 14. METHODS: With this aim, we selected patients sensitized to 1 or both of the 2 allergens, and among these we identified those who were really wheat allergic and reactive on the basis of a standardized methodology...

BACKGROUND: Nonsteroidal anti-inflammatory drug (NSAID) outpatient challenge protocols are not standardized. They vary in clinical practice and can be time- and resource-intensive to perform. OBJECTIVE: To investigate the safety and outcomes of two-step outpatient NSAID challenges to evaluate patients with non-aspirin-exacerbated respiratory disease (AERD)-related NSAID hypersensitivity. METHODS: We conducted a retrospective study of patients with a history of NSAID allergy who underwent outpatient NSAID challenges under allergist supervision...
