Hypersensitivity reaction (HSR) is still a major concern during cancer chemotherapy with paclitaxel. In the present study, we investigated retrospectively the incidence of HSRs to paclitaxel and the risk factors in 105 patients (553 courses) who received adjuvant chemotherapy (paclitaxel and carboplatin) for ovarian cancer. Moderate to severe HSRs that led to cessation or discontinuation of the chemotherapy, including respiratory distress and hypotension, were observed in 14 patients (13.3%) and 16 courses (2.9%), regardless of the use of conventional premedication with glucocorticoid, and histamine H(1) and H(2) antagonists. The incidence of HSRs to paclitaxel in patients with ovarian cancer seemed to be considerably higher than those reported by other investigators in patients with other carcinomas such as non-small-cell lung cancer and breast cancer. Four risk factors were identified: (1) history of mild dermal reactions such as facial flushing and urticaria in previous courses, (2) presence of respiratory dysfunction, (3) obesity (body mass index >25), and (4) postmenopausal at the time of ovariectomy. The incidence of hypersensitivity increased linearly as the number of risk factors increased (r=0.992, P=0.008). It is likely that disappearance of the estrous cycle facilitates the occurrence of HSRs to paclitaxel.

This paper reviews a wide range of somatization-related symptoms that are encountered in dermatology. These include the unexplained cutaneous sensory syndromes especially the cutaneous dysesthesias associated with pain, numbness and pruritus; traumatic memories in post-traumatic stress disorder (PTSD) which are experienced on a sensory level as 'body memories' and may present as local or generalized pruritic states, urticaria and angioedema; and unexplained flushing reactions and profuse perspiration, in addition to unexplained exacerbations of stress-reactive dermatoses such as psoriasis and atopic eczema secondary to the autonomic hyperarousal in PTSD; classic 'pseudoneurologic' symptoms associated with dissociation including unexplained loss of touch or pain, in addition to the self-induced dermatoses such as dermatitis artefacta and trichotillomania that are encountered with dissociative states; and body dysmorphic disorder where the patient often presents with a somatic preoccupation involving the skin or hair.

There are many endocrine conditions that can present with allergic symptoms and signs. Thyroid conditions ranging from fatigue to orbitopathy associated with Grave's disease can be confused with allergic conjunctivitis and angioedema. Autoimmune thyroid disease is commonly associated with idiopathic urticaria. Symptoms of orthostatic hypotension and intolerance often present when least expected and should be considered ahead of time to avoid confusion in treating possible systemic allergic reactions. Flushing is a frequent sign and differentiating from complaints commonly associated with allergic reactions, rosacea, and endocrinopathies is helpful in sorting out some of the more complex conditions associated with this symptom.

The reported incidence of hypersensitivity reactions (HSRs) associated with oxaliplatin in patients with colorectal cancer (CRC) is approximately 12%, with 1 - 2% of patients developing grade 3 or 4 in severity. However, the recent rising incidence of HSR to oxaliplatin observed is the result of increasing clinical use. HSR to oxaliplatin may manifest as facial flushing, rash/hives, tachycardia, dyspnoea, erythema, pruritus, fever, tongue swelling, headache, chills, weakness, vomiting, burning sensations, dizziness and oedema. Anaphylactic shock is rare but serious, and must be considered in the event of hypotension. No definitive approaches to prevent and treat HSR associated with oxaliplatin are available; however, few successful strategies have been reported. Such strategies include: slowing the infusion rate, use of steroids and antagonists of type 1 and 2 histamine receptors, and desensitisation. Successful implementation of oxaliplatin desensitisation protocols based on other platinum-containing compounds have been reported, which could enable a small number of patients who experience severe HSR to further receive an effective therapy for CRC. However, reintroductions have only been reported as single case studies or small cohorts. Large-scale validation on desensitisation strategies are still missing. Recently, subcutaneous adrenaline has also been utilised as an alternative approach to manage HSR to oxaliplatin. Knowledge of this rare but real toxicity of oxaliplatin is paramount because the use of this drug continues to increase not only for the treatment of patients with stage II-IV CRC, but also other solid malignancies. In this article, the author discusses the incidence, clinical presentation, pathogenesis, risk factors and current strategies of management of HSR associated with oxaliplatin.

Allergic and nonallergic reactions to nitroglycerin occur. The aims of this study were to review the different manifestations of nitroglycerin allergy, to explain how to evaluate for it, and to discuss its treatment. We reviewed relevant literature in peer-reviewed journals, computerized databases, and references identified from relevant bibliographics. Nitroglycerin's most common side effects are headache, facial flushing, head throbbing, fainting, hypotension, tachycardia, and syncope. The majority of reported skin reactions to topical and transdermal nitroglycerin products are irritant contact dermatitis, allergic contact dermatitis, and urticaria. Five cases of presumed allergic reactions to oral, sublingual, intravenous, or perianal nitroglycerin products have been described. Patch testing may be helpful in subjects with skin reactions to topical or transdermal nitroglycerin. In subjects with positive patch tests to nitroglycerin (allergic contact dermatitis), transdermal nitroglycerin patches and other topical nitroglycerin products should be avoided. Most patients with contact dermatitis to nitroglycerin have tolerated oral nitroglycerin, sublingual nitroglycerin, or oral isosorbide challenges.

Cutaneous reactions to foods represent one of the most common presentations of food allergy in children. IgE-mediated (urticaria, angioedema, flushing, pruritus), cell-mediated (contact dermatitis, dermatitis herpetiformis), mixed IgE- and cell-mediated (atopic dermatitis), and nonimmune-mediated (irritant contact dermatitis, Frey's syndrome) reactions to foods have all been reported. It is important for the pediatrician to recognize the variety of skin reactions potentially related to food allergy and to consider timely referral to an allergy specialist for further evaluation and definitive diagnosis.

Histamine intolerance results from a disequilibrium of accumulated histamine and the capacity for histamine degradation. Histamine is a biogenic amine that occurs to various degrees in many foods. In healthy persons, dietary histamine can be rapidly detoxified by amine oxidases, whereas persons with low amine oxidase activity are at risk of histamine toxicity. Diamine oxidase (DAO) is the main enzyme for the metabolism of ingested histamine. It has been proposed that DAO, when functioning as a secretory protein, may be responsible for scavenging extracellular histamine after mediator release. Conversely, histamine N-methyltransferase, the other important enzyme inactivating histamine, is a cytosolic protein that can convert histamine only in the intracellular space of cells. An impaired histamine degradation based on reduced DAO activity and the resulting histamine excess may cause numerous symptoms mimicking an allergic reaction. The ingestion of histamine-rich food or of alcohol or drugs that release histamine or block DAO may provoke diarrhea, headache, rhinoconjunctival symptoms, asthma, hypotension, arrhythmia, urticaria, pruritus, flushing, and other conditions in patients with histamine intolerance. Symptoms can be reduced by a histamine-free diet or be eliminated by antihistamines. However, because of the multifaceted nature of the symptoms, the existence of histamine intolerance has been underestimated, and further studies based on double-blind, placebo-controlled provocations are needed. In patients in whom the abovementioned symptoms are triggered by the corresponding substances and who have a negative diagnosis of allergy or internal disorders, histamine intolerance should be considered as an underlying pathomechanism.

Hypersensitivity reactions (HSR) to oxaliplatin in patients with colorectal cancer include facial flushing, erythema, pruritus, fever, tachycardia, dyspnea, tongue swelling, rash/hives, headache, chills, weakness, vomiting, burning sensations, dizziness, and edema. We report a patient with fever as the sole manifestation of initial HSR, review the literature and discuss the management of HSR. A 57-year-old female with T3N2M0 rectal adenocarcinoma received modified FOLFOX-6. She tolerated the first 8 cycles without any toxicities except grade 1 peripheral neuropathy and nausea. During 9th and 10th infusions, she developed fever to a maximum of 38.3 centigrade with stable hemodynamic status despite medications. During 11th infusion, she developed grade 3 HSR consisting of symptomatic bronchospasm, hypotension, nausea, vomiting, cough, and fever. On examination, she was pale, cyanotic, with a temperature of 38.8 centigrade, BP dropped to 95/43 mm Hg, pulse of 116/min and O(2) saturation of 88%-91%. She was hospitalized for management and recovered in 24 h. Fever alone is not a usual symptom of oxaliplatin HSR. It may be indicative that the patient may develop serious reactions subsequently, as did our patient who developed hypotension with the third challenge. Treatment and prevention consists of slowing the infusion rate, use of steroids and antagonists of Type 1 and 2 histamine receptor antagonists, whereas desensitization could help to provide the small number of patients who experience severe HSR with the ability to further receive an effective therapy for their colorectal cancer.

Anaphylaxis is an IgE mediated severe allergic reaction causing release of vasoactive substances from mast cells and basophils after re-exposure to an antigen. Signs and symptoms include flushing, urticaria, hypotension, tachycardia, bronchospasm, cardio-respiratory arrest etc. It can occur at induction of anaesthesia when multiple drugs are being administered, but prompt diagnosis with correct management is the key to a successful outcome. This case report describes a patient who developed severe bronchospasm with difficulty in inflating the lungs and dropping oxygen saturations, alongwith hypotension, tachycardia and widespread flushing, at induction of anaesthesia for elective breast surgery. She was promptly managed and her hypotension was corrected, but the bronchospasm was more resistant to treatment. The patient also developed ST segment elevation, which was successfully managed with intravenous glyceryltrinitrate. The bronchospasm responded slowly to salbutamol and aminophylline. The patient underwent surgery and was discharged home on the third postoperative day.
