Genetic Variants in Cytosolic Phospholipase A2 Associated With Nonsteroidal Anti-Inflammatory Drug-Induced Acute Urticaria/Angioedema.

Front Pharmacol 2021 30;12:667824. Epub 2021 Apr 30.

Allergy Research Group, Instituto De Investigación Biomédica De Málaga-IBIMA, Malaga, Spain.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the main triggers of drug hypersensitivity reactions, probably due to their high consumption worldwide. The most frequent type of NSAID hypersensitivity is NSAID cross-hypersensitivity, in which patients react to NSAIDs from different chemical groups in the absence of a specific immunological response. The underlying mechanism of NSAID cross-hypersensitivity has been linked to cyclooxygenase (COX)-1 inhibition causing an imbalance in the arachidonic acid pathway. Read More

Polymorphisms in eicosanoid-related biosynthesis enzymes associated with acute urticaria/angioedema induced by nonsteroidal anti-inflammatory drug hypersensitivity.

Br J Dermatol 2021 May 6. Epub 2021 May 6.

Allergy Research Group, Instituto de Investigación Biomédica de Málaga-IBIMA, ARADyAL, Malaga, Spain.

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs), probably the most consumed medicines, are the main triggers of drug hypersensitivity, being NSAID-induced acute urticaria/angioedema (NIUA) the most frequent phenotype. NSAID-hypersensitivity is bred by cyclooxygenase (COX)-1 inhibition, which leads to an imbalance in prostaglandin (PG) and cysteinyl-leukotriene (CysLT) synthesis. As only susceptible individuals develop NSAID-hypersensitivity, genetic factors are believed to participate; however, no study has assessed the overall genetic variability of key enzymes in PG and CysLT synthesis in NSAID-hypersensitivity.

Immun Inflamm Dis 2021 May 4. Epub 2021 May 4.

Covid Unit, Istituto Dermopatico dell'Immacolata-IRCCS, FLMM, Rome, Italy.

The coronavirus disease (COVID-19), during its course, may involve several organs, including the skin with a petechial skin rash, urticaria and erythematous rash, or varicella-like eruption, representing an additional effect of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, as commonly observed in other viral diseases. Considering that symptomatic patients with COVID-19 generally undergo multidrug treatments, the occurrence of a possible adverse drug reaction presenting with cutaneous manifestations should be contemplated. Pleomorphic skin eruptions occurred in a 59-year-old Caucasian woman, affected by a stable form of chronic lymphocytic leukemia, and symptomatic SARS-CoV-2 infection, treated with a combination of hydroxychloroquine sulfate, darunavir, ritonavir, sarilumb, omeprazole, ceftriaxone, high-flow oxygen therapy devices, filgrastim (Zarzio®) as a single injection, and enoxaparin.

Viral Infections and Cutaneous Drug-Related Eruptions.

Front Pharmacol 2020 10;11:586407. Epub 2021 Mar 10.

Pediatric Allergy Unit, University Hospitals of Geneva and University of Geneva, Geneva, Switzerland.

In the general population, up to 10% of children treated by antibiotics have cutaneous adverse drug reaction, but allergy is confirmed in less than 20% of patients. Most of the non-allergic reactions are probably due to virus, such as enterovirus acute infection or Ebstein-Barr Virus (EBV) acute infection or reactivation. Especially in children, viruses have the propensity to induce skin lesions (maculopapular rash, urticaria) due to their skin infiltration or immunologic response. Read More
