Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a hypersensitivity reaction associated with a variety of drugs, mainly anticonvulsants, which is characterized by systemic symptoms and erythematous lesions, common to other toxicodermas. It is an uncommon clinical entity that requires a high suspicion by clinical staff given its varied initial presentation, and the fact that symptoms can overlap with those of other adverse cutaneous reactions to drugs. Without early diagnosis and appropriate treatment, mortality increases...

Cisplatin resistance remains a major problem in the treatment of lung cancer. We have discovered that cisplatin resistant (CR) lung cancer cells, regardless of the signaling pathway status, share the common parameter which is an increase in reactive oxygen species (ROS) and undergo metabolic reprogramming. CR cells were no longer addicted to the glycolytic pathway, but rather relied on oxidative metabolism. They took up twice as much glutamine and were highly sensitive to glutamine deprivation. Glutamine is hydrolyzed to glutamate for glutathione synthesis, an essential factor to abrogate high ROS via xCT antiporter...

Hypersensitivity reactions (HSR) to pegylated liposomal doxorubicin (PLD; Caelyx(®)) have been reported, and symptoms usually resolve with drug withdrawal. However, the risk of relapse of severe HSR and prevention remain poorly described. To report the management and outcome in four patients with HSR due to PLD. Patient characteristics, premedication regimen, rate of infusion, time between onset and HSR, clinical manifestations, and management were documented. A first cycle of PLD was received for cutaneous T-cell lymphoma (n = 3) and Kaposi sarcoma (n = 1)...

Drug rash, eosinophilia, and systemic symptoms (DRESS) syndrome is a severe systemic hypersensitivity reaction that usually occurs within 6 weeks of exposure to the offending drug. Diagnosis is usually straightforward in patients with pyrexia, skin rash, hepatitis, and eosinophilia with a preceding history of exposure to agents often associated with DRESS syndrome, such as aromatic anticonvulsants and sulfa drugs, but diagnosis of DRESS may still be a challenge. We report a 4-year-old child with probable DRESS syndrome complicated by multiple hematologic complications that developed 1 month after exposure to fluoxetine, a drug not known to be associated with such severe reactions...

Percutaneous transluminal coronary angioplasty with coronary stent implantation is a life-saving medical procedure that has become, nowadays, the most frequent performed therapeutic procedure in medicine. Plain balloon angioplasty, bare metal stents, first and second generation drug-eluting stents, bioresorbable and bioabsorbable scaffolds have offered diachronically a great advance against coronary artery disease and have enriched our medical armamentarium. Stented areas constitute vulnerable sites for endothelial damage, endothelial dysfunction, flow turbulence, hemorheologic changes, platelet dysfunction, coagulation changes and fibrinolytic disturbances...

Risk factors for intraoperative immediate-type hypersensitivity reactions may require allergological evaluation. We report the case of a hairdresser with a positive history of penicillin hypersensitivity and anaphylactic shock during previous general anesthesia, whose in vivo and in vitro allergy tests were positive for neuromuscular blocking agents, opioids, and midazolam. Immediate-type hypersensitivity reactions to antibiotics and professional exposure to hairdressing products might induce simultaneous cross-sensitization to multiple drugs that are commonly used during general anesthesia...

Available evidence indicates voltage-gated Na(+) channels (VGSCs) in peripheral sensory neurons are essential for the pain and hypersensitivity associated with tissue injury. However, our understanding of the biophysical and pharmacological properties of the channels in sensory neurons is largely based on the study of heterologous systems or rodent tissue, despite evidence that both expression systems and species differences influence these properties. Therefore, we sought to determine the extent to which the biophysical and pharmacological properties of VGSCs were comparable in rat and human sensory neurons...

Oxaliplatin is one of the most commonly used drugs for patients with colorectal cancer. It has rarely been associated with disseminated intravascular coagulation (DIC) with only 3 previously reported cases. In all those instances, the patients had started receiving oxaliplatin, developed evidence of DIC during the course of planned treatment, and recovered with supportive care. We report a case of a 71-year-old man with colorectal cancer treated successfully with an oxaliplatin-based regimen who had disease relapse after 3 years...

Bone cancer pain is a challenge for its not completely clarified mechanism and broad clinical morbidity. Therefore, novel and more effective drugs are urgent needed for improvement of patients' quality of life. Glutamate receptors have been associated with the development of the central sensitization of chronic pain. Inhibition of N-methyl-D-aspartate (NMDA) and metabotropic glutamate (mGlu) receptors can effectively attenuate bone cancer pain respectively. Herein, our results indicated that levo-Corydalmine (l-CDL), a compound from Corydalis yanhusuo W...

Cough is one of the most common complaints for which sufferers seek medical assistance. However, currently available drugs are not very effective in treating cough, particularly that which follows an upper respiratory tract infection. Nonetheless, there has been a significant increase in our understanding of the mechanisms and pathways of the defensive cough as well as the hypersensitive/pathophysiological cough, both at airway and central nervous system (CNS) levels. Numerous molecules and signaling pathways have been identified as potential targets for antitussive drugs, including neurotrophins (NTs)...

PURPOSE: Recently, generic drugs of paclitaxel have been commonly used mainly by economic reasons; however, predictive factors for toxicities are not fully determined. Hypersensitivity reaction (HSR) is one of the most important adverse events in the paclitaxel-based therapy, and sometimes leads to lethal condition. The aim of the study was to identify predictors for HSR in patients treated with paclitaxel-based regimens. METHODS: All the patients treated with chemotherapy including paclitaxel at our hospital between 1998 and 2013 were retrospectively evaluated...

Ultraviolet (UV) radiation exposure induces immunosuppression, which contributes to the development of cutaneous malignancies. We investigated the effects of honokiol, a phytochemical found in plants of the genus Magnolia, on UVB-induced immunosuppression using contact hypersensitivity (CHS) as a model in C3H/HeN mice. Topical application of honokiol (0.5 and 1.0 mg/cm(2) skin area) had a significant preventive effect on UVB-induced suppression of the CHS response. The inflammatory mediators, COX-2 and PGE2, played a key role in this effect, as indicated by honokiol inhibition of cyclooxygenase-2 (COX-2) expression and PGE2 production in the UVB-exposed skin...

BACKGROUND: Penicillins are the drug family most commonly associated with hypersensitivity reactions. Current guidelines recommend negative skin tests (ST) before re-administering penicillins to patients with previous nonimmediate reactions (NIR). OBJECTIVE: The objective of this study was to examine whether ST are necessary before re-administering penicillin to patients with NIR. METHODS: Patients with NIR to penicillins starting longer than 1 hour after last dose administration or starting any time after the first treatment day or patients with vague recollection of their reaction underwent penicillin ST...
