OBJECTIVE: Hypersensitivity reactions (HSR) are frequently reported in patients rechallenged with carboplatin for recurrent ovarian cancer (ROC) and represent a critical issue, since discontinuation of the platinum-based therapy could affect prognosis. Several strategies to allow platinum rechallenge have been described, with controversial outcomes. The aim of this study is to illustrate a 10-year experience with cisplatin in patients with a previous HSR to carboplatin or at risk for allergy...

Elotuzumab is a humanized, immunostimulatory anti-signaling lymphocytic activation molecule F7 (SLAMF7) IgG1 monoclonal antibody indicated in combination with lenalidomide and dexamethasone for patients with multiple myeloma (MM) who have received 1-3 prior therapies. We assessed the immunogenicity of elotuzumab as a monotherapy and in combination with bortezomib/dexamethasone and lenalidomide/dexamethasone in patients with MM in five clinical studies, including the pivotal ELOQUENT-2 trial (NCT01239797). Anti-drug antibody (ADA) prevalence was determined using a validated bridging assay...

There is experimental and clinical evidence that some exanthematous allergic drug hypersensitivity reactions are mediated by drug-specific T cells. We hypothesized that the capacity of certain drugs to directly stimulate the innate immune system may contribute to generate drug-specific T cells. Here we analyzed whether abacavir, an HIV-1 reverse transcriptase inhibitor often inducing severe delayed-type drug hypersensitivity, can trigger innate immune activation that may contribute to its allergic potential...

The Adverse Drug Reaction (ADR) to a commonly prescribed anti-microbial can pose a major public health problem. The authors report a rare case of 24-year-old young lady who presented with angioedema of lips after ingestion of Ofloxacin, prescribed to her for treatment of loose motions. Fluoroquinolones are widely prescribed antibiotics for various disease conditions. The history, clinical examination and normal laboratory parameters led to the diagnosis of ofloxacin induced hypersensitivity reaction and the patient was successfully treated with corticosteroids and antihistamines...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDS) are among the most common causes of drug hypersensitivity (HS) reactions. The diagnosis is based on a careful clinical history, and provocation tests are considered the gold standard for diagnosis. Skin tests have some value to study reactions to pyrazolones. Laboratory investigations are mostly used for research purposes. Different phenotypes have been described. OBJECTIVE AND METHODS: Our aim was to describe the most common clinical manifestations of NSAID HS in a large population of adult patients, the drugs involved, the association with previously described risk factors, and the outcome of diagnostic procedures...

BACKGROUND: Rapid drug desensitization (RDD) has become a cornerstone in the management of immediate drug hypersensitivity reactions (DHRs) to chemotherapeutic agents. Because of the inherent risk of anaphylaxis during RDD, biomarkers to predict patients at risk of developing such severe reactions are needed. The basophil activation test (BAT) has been used in DHRs as a diagnostic tool. OBJECTIVE: We evaluated basophil CD63 and CD203c expression (BAT) as a biomarker to assess the safety and effectiveness of RDD in platinum compounds-allergic patients...

REVIEW
Toru Usui, Dean J Naisbitt
A clinical association between a specific human leukocyte antigen (HLA) allele and idiosyncratic adverse drug reactions (IADRs) is a strong indication that IADRs are mediated by the adaptive immune system. For example, it is well-established that HLA-B*15:02 and HLA-B*57:01 are associated with carbamazepine-induced Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) and abacavir-induced hypersensitivity/flucloxacillin-induced liver injury, respectively. Drug-specific T-cells whose response is restricted by specific HLA risk alleles have been detected from IADR patients, also suggesting an adaptive immune pathogenesis...

BACKGROUND: Lamotrigine is an anticonvulsant as well as a mood stabilizer. Apart from its established use in the treatment of epilepsy, there has been an expansion of its use in the treatment of mental disorders. Patients with epilepsy as well as those with mental disorders are at increased risk of deliberate drug overdoses. An evidence base for the safety profile of lamotrigine in overdose is an essential tool for prescribers. The objective of this study was to carry out a narrative synthesis of the existing evidence for the safety profile of lamotrigine in overdose...

Erythema exsudativum multiforme is an immunologically mediated skin condition caused by viruses, bacteria, food, and drugs. There are different forms, and depending on the severity of the disease there is a major and minor form. Whereas the minor form passes without consequences, the major form and Stevens-Johnson syndrome affect the mucosa and may result in death. The disease affects all age groups but is more often observed in young individuals. Typical signs of the disease are skin lesions termed herpes iris...

REVIEW
C Möbs, W Pfützner
Drug hypersensitivity reactions comprise approximately 25% of all adverse drug reactions and can be classified into allergic and pseudoallergic drug reactions. Immediate type anaphylactic and delayed type rash reactions of various clinical patterns can be distinguished, depending on the pathogenesis and clinical symptoms. The diagnostic work-up encompasses a thorough but also focused evaluation of the medical history, skin tests and when indicated challenge tests. Furthermore, in vitro tests, such as basophil activation tests and T cell assays not only add valuable additional information but can also yield decisive results for the diagnosis, especially in cases of severe drug reactions or reactions which cannot be further clarified by provocation tests...

Intramuscular teicoplanin (400 mg every 12 h for three doses, then 400 mg daily, intramuscularly) was prescribed for a 37-year-old woman with presumptive diagnosis of cellulitis. On the 14th day of treatment, she developed generalized maculopapular rash, accompanied by fever, wheezing, shortening of breath, and lymphadenopathy. Lab tests revealed abnormal liver enzymes, leukocytosis, and eosinophilia. The treatment was interrupted with suspicion of drug reaction. Fever subsided after 48 h. Skin eruption and respiratory symptoms began to resolve within 2 weeks...

The discovery that several drug hypersensitivity reactions (DHRs) are associated with specific human leukocyte antigen (HLA) alleles has attracted increasing research interest. However, the underlying mechanisms of these HLA-induced DHRs remain unclear, especially for drug-induced immediate activation of T-cell clones (TCCs). Recently, a novel hypothesis involving partial detachment between self-peptide(s) and the HLA molecule (altered peptide-HLA (pHLA) model) has been proposed to explain these phenomena. In order to clarify this hypothesis, we performed long-timescale molecular dynamics (MD) simulations...

BACKGROUND: Polyethylene glycols (PEGs) or macrogols are polyether compounds and are widely used as additives in pharmaceuticals, cosmetics, and food. CASE REPORT: We report on a Caucasian patient experiencing recurrent severe allergic reactions to several drugs. An extensive diagnostic workup including skin prick tests, intradermal tests (IDT) and a double-blind oral challenge was performed to identify the trigger of anaphylaxis. In the present case hypersensitivity to the additive polyethylene glycol was confirmed by an IDT suggesting an Immunoglobulin E-dependent mechanism as a cause of the reaction...

Drug hypersensitivity reactions affect over 7% of the population and are problematic both for patients and doctors. They frequently occur in the form of exanthematous drug eruptions. The clinical manifestation of delayed hypersensitivity reactions is very variable ranging from localized fixed drug eruptions to life-threatening, severe bullous mucocutaneous eruptions or systemic drug hypersensitivity syndromes. In the case of suspicion of an exanthematous drug eruption, the causality should initially be assessed according to the proposed algorithm...

: Ergosterol, a fungal specific sterol enriched in cell plasma membranes, is an effective antifungal drug target. However, current knowledge of the ergosterol biosynthesis process in the saprophytic human fungal pathogen Aspergillus fumigatus remains limited. In this study, we identified that two endoplasmic reticulum-localized sterol C-24 reductases encoded by both erg4A and erg4B homologs are required to catalyze the reaction during the final step of ergosterol biosynthesis. Loss of one homolog of Erg4 induces the over-expression of the other one, accompanied with almost normal ergosterol synthesis and the wild-type colony growth...
