Tariq Azamgarhi, Ashik Shah, Simon Warren
BACKGROUND: The rate of true anaphylaxis to teicoplanin is currently unknown. METHODS: A case-series including all suspected anaphylactic reactions attributed to teicoplanin anaphylaxis within a single institution over a 29-month period were categorised according to the probability of true IgE mediated anaphylaxis using previously published criteria. The number of patients who receive Teicoplanin was determined and used to calculate the rate of IgE mediated anaphylaxis...

The development of an effective and safe vaccine to prevent Toxoplasma gondii infection is an important aim due to the great clinical and economic impact of this parasitosis. We have previously demonstrated that immunization with the serine protease inhibitor-1 (TgPI-1) confers partial protection to C3H/HeN and C57BL/6 mice. In order to improve the level of protection, in this work, we combined this novel antigen with ROP2 and/or GRA4 recombinant proteins (rTgPI-1+rROP2, rTgPI-1+rGRA4, rTgPI-1+rROP2+rGRA4) to explore the best combination against chronic toxoplasmosis in C3H/HeN mice...

Children are at risk of rabies exposure in many Asian countries. The safety and immunogenicity profile of the WHO-approved two-site intradermal Thai Red Cross regimen (modified TRC-ID regimen; 2-2-2-0-2) with a new chromatographically purified Vero-cell rabies vaccine (CPRV) is lacking. Area covered: We studied the safety and immunogenicity of the TRC-ID regimen with a new CPRV in non-immunized Thai children with possible or proven rabies exposure. Thirty-nine seronegative patients (age range 2-14 years) with rabies exposure (WHO categories II or III) received two 0...

Manifestations of Leishmania infantum infection range from asymptomatic to symptomatic visceral leishmaniasis (VL). People with symptomatic VL (sVL) have suppressed immune responses against Leishmania antigens that are reversed after clinical cure. The intradermal leishmanin skin test (LST) is negative during sVL, but it becomes positive after treatment. The aim of this study was to compare T cell responses in individuals with sVL, recovered VL (RecVL), and endemic controls. Endemic controls were household contacts of a VL case and they were grouped by their LST results, either positive (LST+) or negative (LST-)...

Background. The term of α-Gal syndrome, which includes the delayed allergy to red meat and the allergic reactions following the administration of cetuximab, is associated to the presence of specific IgE to α-Gal. In Italy, only anecdotal cases were reported so far. The Association of Italian Allergists (AAITO) carried out a survey with the aim of evaluating presence, characteristics, clinical features, and distribution of the syndrome in Italy. Methods. A web structured questionnaire was made available on the website of AAIITO from July 2016 to January 2017...

Local skin heating to 42°C causes rapid increases in cutaneous perfusion (initial peak), followed by a brief nadir and subsequent sustained elevation (plateau). Several studies have demonstrated that nitric oxide synthase (NOS) largely contributes to the plateau response during local heating. In this study, we tested the hypothesis that voltage-gated potassium (Kv) channels contribute to the plateau of the cutaneous vasodilation during local heating through NOS-dependent mechanisms. Eleven young males (25±4years) participated in this study wherein cutaneous vascular conductance (CVC) was measured at four intradermal microdialysis sites that were continuously perfused with either 1) lactated Ringer (Control), 2) 10mM 4-aminopyridine (Kv channel blocker), 3) 10mM Nω-Nitro-L-arginine (NOS inhibitor), or 4) a combination of 4-aminopyridine and Nω-Nitro-L-arginine...

RATIONALE: Anaphylaxis is a serious, generalized allergic reaction typically triggered by drugs, food, and bee venom, which can be life-threatening. Seeds are one of the major food allergens and can cause anaphylaxis as well as systemic hypersensitivity reactions. Flaxseed has been widely used crop for numerous purposes, such as in alternative medicine and as a dietary supplement, hypersensitivity to it has rarely been reported. PATIENT CONCERNS: A 42-year-old female presenting with facial edema, dyspnea and urticaria after ingested half teaspoon of flaxseed flour 30 minutes previously...

Development of effective vaccine candidates against tuberculosis (TB) is currently the most important challenge in the prevention of this disease since the BCG vaccine fails to guarantee a lifelong protection, while any other approved vaccine with better efficiency is still absent. The protective effect of the recombinant fusion protein CFP10-ESAT6-dIFN produced in a prokaryotic expression system (Escherichia coli) has been assessed in a guinea pig model of acute TB. The tested antigen comprises the Mycobacterium tuberculosis (Mtb) proteins ESAT6 and CFP10 as well as modified human γ-interferon (dIFN) for boosting the immune response...

BACKGROUND: There has been little investigation regarding air quality and rhinitis in the pathophysiology of upper airway disease. In this study, we assessed the impact of inhalant pollutants (particulate matter 2.5 [PM2.5 ] and black carbon [BC]) on allergic rhinitis and chronic rhinosinusitis (CRS) disease severity. METHODS: CRS patients with nasal polyps (CRSwNP) and without polyps (CRSsNP) were identified. Spatial modeling from pollutant monitoring sites was used to estimate exposures for patients meeting the inclusion criteria (total, n = 125; CRSsNP, n = 67; CRSsNP, n = 58)...

BACKGROUND: Nexvax2® is a novel, peptide-based, epitope-specific immunotherapy intended to be administered by regular injections at dose levels that increase the threshold for clinical reactivity to natural exposure to gluten and ultimately restore tolerance to gluten in patients with celiac disease. Celiac disease patients administered fixed intradermal doses of Nexvax2 become unresponsive to the HLA-DQ2·5-restricted gluten epitopes in Nexvax2, but gastrointestinal symptoms and cytokine release mimicking gluten exposure, that accompany the first dose, limit the maximum tolerated dose to 150μg...

BACKGROUND: Red deer (Cervus elaphus) is regarded as an epidemiologically relevant host for Mycobacterium bovis (M. bovis) and closely related members of the Mycobacterium tuberculosis complex that cause animal tuberculosis (TB). The standard antemortem screening test for the detection of TB in deer is the intradermal tuberculin skin test, but the detection of interferon-gamma (IFNγ) produced by white blood cells exposed to M. bovis antigens can be used as an alternative or supplemental assay in most TB eradication/control programs...

Current research on wound infections is primarily conducted on animal models, which limits direct transferability of these studies to humans. Some of these limitations can be overcome by using-otherwise discarded-skin from cosmetic surgeries. Superficial wounds are induced in fresh ex vivo skin, followed by intradermal injection of Pseudomonas aeruginosa under the wound. Subsequently, the infected skin is incubated for 20 hours at 37°C and the CFU/wound are determined. Within 20 hours, the bacteria count increased from 107 to 109 bacteria per wound, while microscopy revealed a dense bacterial community in the collagen network of the upper wound layers as well as numerous bacteria scattered in the dermis...
