Low Cross-Reactivity Between Cisplatin and Other Platinum Salts.
2019
Background Hypersensitivity reactions to platinum salts (PS) (cisplatin [CI], carboplatin [CA], and oxaliplatin [OX]) can be severe and their incidence is increasing due to their widespread use in cancer treatment. Objective To determine the rate of cross-reactivity between PS and whether CI can be administered without prior allergy testing in patients with a history of CA or OX hypersensitivity. Methods From September 2002 to April 2016, patients with suspected immediate PS hypersensitivity were tested and cross-reactivity between the 3 PS was evaluated. We then studied patients who were given CI without desensitization after immediate hypersensitivity to other PS. Results A total of 155 p…
Fatal multi-organ failure following anaphylactic shock induced by ceftriaxone
2014
In the latest years, based on the wide use of cephalosporins for antibiotic therapy, a large interest focused on the identification of causal relationship of adverse reactions after their prescription. We report a case of fatal anaphylactic shock following the administration of ceftriaxone in a woman who had tolerated the previous exposure to the drug. This case adds a contribution to the few cases reported in literature to further suggest the possibility of severe anaphylaxis after the administration of ceftriaxone even in patients without any previous reaction to this drug.
EAACI Position paper on the standardization of nasal allergen challenges.

DR. FARID, S.H. M.H. M. Kn. - FR FARID/0000-0003-0372-4963; Gevaert, Philippe/0000-0002-1629-8468; Hox, Valerie/0000-0003-2390-294X; Wagenman, Martin/0000-0002-9734-0241; Vent, Julia/0000-0001-5071-9580 WOS: 000438710600002 PubMed: 29377177 Nasal allergen challenge (NAC) is an important tool to diagnose allergic rhinitis. In daily clinical routine, experimentally, or when measuring therapeutic success clinically, nasal allergen challenge is fundamental. It is further one of the key diagnostic tools when initiating specific allergen immunotherapy. So far, national recommendations offered guidance on its execution; however, international divergence left many questions unanswered. These differ…
Epileptic seizures as a manifestation of cow's milk allergy: a studied relationship and description of our pediatric experience
2014
Adverse reactions after ingestion of cow's milk proteins can occur at any age, from birth and even amongst exclusively breast-fed infants, although not all of these are hypersensitivity reactions. The most common presentations related to cow's milk protein allergy are skin reactions, failure to thrive, anaphylaxis as well as gastrointestinal and respiratory disorders. In addition, several cases of cow's milk protein allergy in the literature have documented neurological involvement, manifesting with convulsive seizures in children. This may be due to CNS spread of a peripheral inflammatory response. Furthermore, there is evidence that pro-inflammatory cytokines are responsible for disruptin…
Different clinical allergological features of
2016
The tapeworm Taenia (T.) solium can be responsible for two different conditions: taeniasis and cysticercosis. Helminth infections in human host cause an immune response associated with elevated levels of IgE, tissue eosinophilia and mastocytosis, and with the presence of CD4+ T cells that preferentially produce IL-4, IL-5, and IL-13. Individuals exposed to helminth infections may have allergic inflammatory responses to parasites and parasite antigens. PubMed search of human cases of allergic reactions occurring during T. solium infestation was performed combining the terms (allergy, urticaria, angioedema, asthma, anaphylaxis) with T. solium. A study was considered eligible for inclusion in …
Ability of the T cell-replacing polyanion dextran sulfate to trigger the alternate pathway of complement activation.
1973
Dextran sulfate (DS) consumed C3 in C4 deficient guinea pig serum. This temperature-dependent reaction required Mg++ ions and could therefore be blocked by EDTA. Isolated C3 was not influenced by DS, but serum factors were required for C3 consumption. The C3 proactivator as well as C3 were converted to their activated state by DS in guinea pig and human serum, as revealed by immunoelectrophoretical analysis. DS generated anaphylatoxin activity in serum. It is concluded that DS activates C3 via the alternate pathway of complement activation. This potency of the polyanion might serve as a tentative explanation for its T cell-replacing effect in an antibody-forming system, which was reported b…
Cre-mediated cell ablation contests mast cell contribution in models of antibody- and T cell-mediated autoimmunity.
2011
SummaryImmunological functions of mast cells remain poorly understood. Studies in Kit mutant mice suggest key roles for mast cells in certain antibody- and T cell-mediated autoimmune diseases. However, Kit mutations affect multiple cell types of both immune and nonimmune origin. Here, we show that targeted insertion of Cre-recombinase into the mast cell carboxypeptidase A3 locus deleted mast cells in connective and mucosal tissues by a genotoxic Trp53-dependent mechanism. Cre-mediated mast cell eradication (Cre-Master) mice had, with the exception of a lack of mast cells and reduced basophils, a normal immune system. Cre-Master mice were refractory to IgE-mediated anaphylaxis, and this defe…
Hauttestungen mit Nahrungsmittelallergenen
2008
Hauttestungen haben einen zentralen Stellenwert in der Abklarung von Sensibilisierungen bei Nahrungsmittelallergien. Insbesondere der Pricktest stellt eine Routinemethode dar. Allerdings komplizieren instabile Allergene und das Fehlen standardisierter Extrakte das diagnostische Vorgehen bei Verdacht auf eine Nahrungsmittelallergie. Deswegen ist man nach wie vor auf einen Prick-zu-Prick-Test mit nativen Lebensmitteln angewiesen. Indikationen und Kontraindikationen fur eine Hauttestung mit Nahrungsmittelallergenen unterscheiden sich nicht wesentlich von anderen Allergien. Vorsicht ist bei Zustand nach schwerer anaphylaktischer Reaktion und bei bekannter hoher allergener Potenz der Nahrungsmit…
Zespół Kounisa – interdyscyplinarny problem na styku alergologii i kardiologii
2021
Anafilaksja oznacza zagrażającą życiu, uogólnioną reakcję nadwrażliwości mogącą mieć charakter alergiczny lub niealergiczny. Zespół Kounisa to ostry zespół wieńcowy spowodowany reakcją alergiczną. Wśród czynników etiologicznych wyzwalających reakcję alergiczną wymienia się pokarmy, czynniki środowiskowe, leki, radiologiczne środki kontrastowe oraz niektóre stany chorobowe. Zespół Kounisa jest stosunkowo rzadko rozpoznawaną przyczyną zawału serca, co najprawdopodobniej wynika z jego niedorozpoznawalności. Przedstawiono przypadek pacjenta z wywiadem choroby niedokrwiennej serca, po zabiegach angioplastyki wieńcowej. Do momentu użądlenia przez owada przebieg dławicy miał charakter stabilny. Pr…
Management of allergic disease in the elderly: key considerations, recommendations and emerging therapies
2015
The number of people over 65 is increasing around the world. At present, between 5 and 10% of allergic diseases affect the elderly. In particular, rhinitis is increasing worldwide; the presence of high comorbidity makes the therapy of asthma even more complicated. With reference to dermatological allergies, the dryness of the skin favors the onset of allergic contact and atopic dermatitis, while the senescence of mucous membranes and the impaired secretion of polymeric IgA could be linked to food allergy. Overcoming the problem of adverse drug reaction is limited by the diagnostic difficulty in patients taking multiple drugs. In addition, some drugs, such as β-blockers, angiotensin-converti…
