Background:Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the leading causes of hypersensitivity reactions to drugs. The pathogenesis may be immunological mechanisms (allergic reactions) or non specific immunological reactions often incriminated in cross reactivity independently of chemical structure of these molecules. Understanding of the underlying mechanism is necessary for prevention and choice of safe alternatives [1, 2].Objectives:Analyze all cases of non-steroidal anti-inflammatory drugs cutaneous eruption reported to sfax pharmacovigilance service since January 2015 to December 2020 and evaluate the possibility of cross-reactions between different molecules in this class.Methods:We conducted a retrospective study of all cases reported to sfax pharmacovigilance department. An enquiry of pharmacovigilance was performed in patients who presented side effects to AINS. The imputability study was carried out by the French method of Imputability. Medical history specifies if there is a re-administration to assess tolerance and cross-reactivity.Results:Our study included 87 patients whose average age was 45, 8 years. The sex ratio (F/M) was 1.18. lysine salicylate acetyl is the most incriminated (31%), then mefenamic acid (19.5%), diclofenac (19.5 %), ketoprofen in (9.2%), piroxicam in (6.9 %), ibuprofen in (5.4%), celocoxib in (3.4%), tiaprofenic acid in (1.1%) and naproxen in 1.1% of cases. The most common skin injury was urticaria in 29 cases (33.3%). Fixed drug eruption was observed in 17 cases. Maculopapular rash was observed in 19 cases, anaphylaxis in 5 cases and 4 cases of photosensitivity were observed. In our study we found cross-reactivity between (NSAIDs) in 8 patients.Conclusion:The diagnostic approach is often based on the controlled administration of the drug to assess tolerance and to identify safe alternatives. In cases of intolerance to COX 1 inhibitors, cross-reactions to selective cox 2 inhibitors are very rare [3].References:[1]Inmaculada Dona, Maria Salas, James R Perkins and al.

The role of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) in neurosurgical practice is a secondary one, however they are still constantly involved in perioperative management of pain or in nonoperative management of acute radiculopathy. Beside the well-known adverse reactions (ADRs), the neurosurgeon practitioner should also take in account the drug hypersensitivity reactions (DHRs) of NSAIDs and be able to deal with it. The aim of this paper was to review the diagnostic and management steps for NSAIDs-induced Hypersensitivity Reactions. The actual stratification of NSAIDs-induced Hypersensitivity Reactions is based on understanding of the heterogeneity of immunological/non-immunological mechanisms of reactions and complexity of clinical manifestations. Practically, this stratification allows the physician to assess suspicion of DHR, based on anamnesis and clinical analysis, and to consider further practical steps to manage and eventually confirm the diagnosis. Drug allergies are considered only the DHRs for which a definite immunological mechanism (either drug-specific antibody or T cell) is demonstrated. In conclusion, clinical analysis and anamnesis of patient with NSAIDs-induced Hypersensitivity Reactions can be realized by any physician and could be enough to diagnose, but it is not sufficient to confirm the diagnosis. In vitro tests and oral provocation challenges may be necessary to be undertaken by an allergy specialist.

Non-steroidal anti-inflammatory drugs (NSAIDs) are the main triggers of drug hypersensitivity reactions in children. According to the EAACI latest classification NSAIDs hypersensitivity reactions are differentiated into cross-reactive reactions, with non-immunological mechanisms (based on COX-1 inhibition), and selective reactions, with immunological mechanisms. Paediatric clinical manifestations of NSAID hypersensitivity are typically cutaneous, but sometimes, similarly to anaphylaxis, can involve other systems, especially the respiratory one. Differentiating between NSAID intolerance and NSAID allergy through drug provocation tests is crucial for the patient because the two clinical entities require different management.

Delayed Hypersensitivity Reaction

We present the unique case of a 33-year-old male referred to our clinic in search of analgesic options who was found to have a delayed hypersensitivity reaction to ibuprofen manifesting as a maculopapular rash and acute urticaria to acetaminophen. Non-steroidal anti-inflammatory drugs are associated with predictable reactions as well as immunoglobulin E-mediated reactions or T-cell mediated reactions. This case highlights the importance of knowledge of the different types of reactions to non-steroidal anti-inflammatory agents as well as the risk of cross reactivity. Delayed reaction to a single non-steroidal agent is rare; urticaria to acetaminophen is very rare. This is the first report we have found in the literature where one individual has a delayed reaction manifesting as rash to ibuprofen as well as urticaria to acetaminophen. We challenged our patient to aspirin which helped identify that his delayed reaction was only to ibuprofen and urticaria only to acetaminophen. The case also highlights the importance of an oral provocation challenge when no contraindications exist which helped us find that he could take celecoxib and avoid narcotics as initial therapy.

Privileged Structures

Rheumatoid arthritis, arthrosis and gout, among other chronic inflammatory diseases are public health problems and represent major therapeutic challenges. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed clinical treatments, despite their severe side effects and their exclusive action in improving symptoms, without effectively promoting the cure. However, recent advances in the fields of pharmacology, medicinal chemistry, and chemoinformatics have provided valuable information and opportunities for development of new anti-inflammatory drug candidates. For drug design and discovery, thiophene derivatives are privileged structures. Thiophene-based compounds, like the commercial drugs Tinoridine and Tiaprofenic acid, are known for their anti-inflammatory properties. The present review provides an update on the role of thiophene-based derivatives in inflammation. Studies on mechanisms of action, interactions with receptors (especially against cyclooxygenase (COX) and lipoxygenase (LOX)), and structure-activity relationships are also presented and discussed. The results demonstrate the importance of thiophene-based compounds as privileged structures for the design and discovery of novel anti-inflammatory agents. The studies reveal important structural characteristics. The presence of carboxylic acids, esters, amines, and amides, as well as methyl and methoxy groups, has been frequently described, and highlights the importance of these groups for anti-inflammatory activity and biological target recognition, especially for inhibition of COX and LOX enzymes.

The effects of piroxicam, tenoxicam, diclofenac sodium, acetylsalicylic acid and tiaprofenic acid on the chemotaxis and random migration of human polymorphonuclear leukocytes were investigated, using zymosan-activated serum as chemo-attractant, with a modified Boyden chamber technique. All five compounds significantly reduced chemotaxis. The random migration of polymorphonuclear leukocytes was inhibited by piroxicam, diclofenac sodium and tiaprofenic acid but not by tenoxicam or acetylsalicylic acid. The inhibitory effect of these non-steroidal anti-inflammatory drugs on polymorphonuclear leukocyte chemotaxis and on random migration was generally dose-dependent. The results suggest that the drugs studied may have a direct effect on polymorphonuclear leukocyte chemotaxis and that this activity may contribute to their anti-inflammatory properties.
