BACKGROUND: Drug provocation test (DPT) represents the gold standard for the diagnosis of drug allergy. A DPT can be performed in a single-blind placebo-controlled manner. In anxiety and depressive disorders, patients need to be evaluated to understand the nature of placebo reactions. OBJECTIVE: The aim of this study was to evaluate the psychological profile of patients with reactions to placebo during a DPT. METHODS: We consecutively enrolled patients with suspected drug allergy undergoing a DPT preceded by the administration of the placebo...

BACKGROUND: Proton pump inhibitors (PPIs) are commonly used to treat gastrointestinal diseases. Incidence of hypersensitivity reactions to PPIs has risen, likely because of increased consumption. Their diagnosis is difficult, with skin tests (STs) presenting low sensitivity, making it necessary to perform drug provocation tests (DPTs). The value of in vitro tests for the diagnosis of immediate reaction to PPI is unclear. OBJECTIVE: To analyze the diagnostic value of the basophil activation test (BAT) in a group of patients diagnosed with immediate allergy to omeprazole...

FePt-Cys nanoparticles (FePt-Cys NPs) have been well used in many fields, despite their poor solubility and stability. We synthetized a cysteine surface modified FePt NPs, which exhibited good solubility, stability and biocompatibility. We explored the insight mechanisms of the antitumor effects of this new nanoparticle system in lung cancer cells. In the in vitro study, FePt-Cys NPs induced a reactive oxygen species (ROS) burst, which suppressed the antioxidant protein expression and induced cell apoptosis...

BACKGROUND: Middle East respiratory syndrome (MERS) is a severe respiratory illness with an overall mortality of 35%. There is no licensed or proven treatment. Passive immunotherapy approaches are being developed to prevent and treat several human medical conditions where alternative therapeutic options are absent. We report the safety of a fully human polyclonal IgG antibody (SAB-301) produced from the hyperimmune plasma of transchromosomic cattle immunised with a MERS coronavirus vaccine...

Tree nut allergy affects approximately 1.4-2.3%, depending on the study methodology, patient age, and region in which the study was conducted.1,2 Tree nut allergy can be severe, and tends to persist throughout life.1,3 Tree nut is not a singular allergen like the other allergens-we use the term "tree nut" to refer to these items, but in essence it can refer to one nut, eight nuts, or per the US Food and Drug Agency classification, on the order of 19 items.1,4 Older, more conservative practice is to treat one nut as "all nuts", and instruct avoidance of all tree nuts where there is a clinical allergy proven to just one...

Ambrosia artemisiifolia L. (common ragweed) is an invasive weed, well-known for the strong allergenic effect of its pollen, as well as for its invasiveness and impact in crop fields (e.g. causing yield losses). This species produces a broad range of sesquiterpenoids. In recent years, new bioactive molecules have been discovered in this plant, e.g. isabelin, a sesquiterpene dilactone. The bioactivity of isabelin has been already demonstrated on allergy-related receptors and its inhibitory effect on seeds of various plant species...

Eric M Macy
Radiocontrast-associated acute-onset hypersensitivity reactions now occur less frequently than before 1990, when high-osmolar, ionic, radiocontrast agents were widely used. Premedication with corticosteroids and antihistamines does not reliably prevent recurrent low-osmolar radiocontrast-associated acute hypersensitivity reactions. Corticosteroid prophylaxis for acute hypersensitivity currently causes more morbidity than benefit. The specific radiocontrast agent that is associated with a patient's adverse reaction must be displayed in the drug intolerance or drug "allergy" field of their electronic health record to enable effective management and prevention of future reactions...

Background: The purpose of this study was to identify chronic urticaria (CU) etiologies and treatment modalities in Ecuador. We propose that the sample distribution fits the expected one, and that there is an association between the etiology and its treatment. Methods: We performed a retrospective study involving 112 patients diagnosed with CU using a Checklist for a complete chronic urticaria medical history. Demographic and clinical variables were collected. The etiology of CU was classified using the EAACI/GA2LEN/EDF/WAO guideline...

REVIEW
Thanai Pongdee, James T Li
Penicillin allergy is the most commonly reported drug allergy in the United States. Although penicillin allergy is widely reported, 80% to 90% of individuals with self-reported penicillin allergy are actually able to tolerate penicillins after undergoing evaluation for penicillin allergy. Because most patients with self-reported penicillin allergy will have subsequent negative allergy testing results and tolerate penicillins, they may be unnecessarily exposed to broader-spectrum antibiotics. Use of such antibiotics leads to increased risks of developing antibiotic-resistant microorganisms and incur higher health care utilization costs...

BACKGROUND: Microbiologic studies suggest that complicated (CAA) and uncomplicated (UAA) acute appendicitis are different entities. Routine peritoneal fluid cultures continue to be controversially related to a low positive rate, found mainly in UAA; to isolation of typical micro-organisms with expected susceptibilities; and to a community-acquired intra-abdominal infection. The aim of this study was to describe microbiologic isolates in CAA and UAA and the usefulness of peritoneal fluid cultures to determine the susceptibilities to our antibiotic therapy guidelines...

Allergic rhinitis (AR) affects ca. 20% of the population. Approximately one third of patients affected by AR are suffering from perennial rhinitis due to mite allergy. Perennial rhinitis is the form of the disease that is most frequently associated with other allergy-related comorbidities such as asthma and atopic dermatitis, sleep disorders, chronic sinusitis, eustachian tube dysfunction and others.The often non-specific symptoms and the insidious course may lead to misinterpretations in diagnosing the disease...

BACKGROUND: Despite current therapies, diffuse cutaneous systemic sclerosis (scleroderma) often has a devastating outcome. We compared myeloablative CD34+ selected autologous hematopoietic stem-cell transplantation with immunosuppression by means of 12 monthly infusions of cyclophosphamide in patients with scleroderma. METHODS: We randomly assigned adults (18 to 69 years of age) with severe scleroderma to undergo myeloablative autologous stem-cell transplantation (36 participants) or to receive cyclophosphamide (39 participants)...

FOXP3+ regulatory T cell (Treg) based cellular therapies represent promising therapeutic options in autoimmunity, allergy, transplantation and prevention of Graft Versus Host (GVH) Disease. Among human FOXP3-expressing CD4+T cells, only the CD45RA+ naïve Treg (nTreg) subset is suitable for in vitro expansion. However, FoxP3 expression decays in cells using currently described culture protocols. Rapamycin alone was not able to prevent FOXP3 loss in nTregs cells, as only a half of them maintained FOXP3 expression after 14 days of culture...

A 51-year-old woman with a history of asthma and Hashimoto's thyroiditis presented to the dermatology service with a chief complaint of "itchy bumpy rashes" that persisted beyond 24 hours. She noted that, 3 days prior to the onset of urticaria, a pyrroloquinoline quinone supplement had been started. The urticaria was accompanied by variable episodes of transient facial swelling and difficulty breathing. The patient noted that exposure to fish, nuts, and nonsteroidal anti-inflammatory drugs triggered facial swelling...
