Radiocontrast media hypersensitivity: skin testing differentiates allergy from non-allergic reactions and identifies a safe alternative as proven by intravenous provocation.

J Allergy Clin Immunol Pract 2019 Apr 10. Epub 2019 Apr 10.

Department of Dermatology and Allergy, University Hospital Würzburg, Germany.

Background: Hypersensitivity reactions occurring within minutes after intravascular injection of iodinated radiocontrast media (RCM) are common and have been previously considered to be non-allergic. However, in the last decades, evidence is increasing that also genuine RCM allergy may present as either full-blown anaphylaxis or delayed exanthematous skin reaction.

Objectives: We aimed to assess whether allergy diagnostics including skin and provocation testing can differentiate between non-allergic and allergic RCM hypersensitivity by identifying the causative RCM as well as tolerated alternative RCM. Read More

Dendritic Cells and T Cells Interact Within Murine Afferent Lymphatic Capillaries.

Front Immunol 2019 22;10:520. Epub 2019 Mar 22.

Institute of Pharmaceutical Sciences, ETH Zürich, Zurich, Switzerland.

Afferent lymphatic vessels contribute to immunity by transporting antigen and leukocytes to draining lymph nodes (LNs) and are emerging as new players in the regulation of peripheral tolerance. Performing intravital microscopy in inflamed murine ear skin we found that migrating dendritic cells (DCs) and antigen-experienced effector T cells spend considerable time arresting or clustering within afferent lymphatic capillaries. We also observed that intralymphatic T cells frequently interacted with DCs. Read More

Management of mycosis fungoides-type cutaneous T-cell lymphoma (MF-CTCL): focus on chlormethine gel.

Cancer Manag Res 2019 20;11:2241-2251. Epub 2019 Mar 20.

Dermatology Department, Centre Hospitalier Le Mans, Le Mans, France,

Mycosis fungoides (MF) is a low-grade cutaneous lymphoma accounting for more than half of primary cutaneous T-cell lymphomas (CTCLs). Due to the rarity of CTCL, randomized studies are lacking, and treatment is based mainly on the recent published European Organisation for Research and Treatment of Cancer guidelines. Basically, early-stage MF is treated with skin-directed treatments, whereas advanced-stage MF requires more aggressive therapies. Read More

The alpha-Gal syndrome: new insights into the tick-host conflict and cooperation.

Parasit Vectors 2019 Apr 3;12(1):154. Epub 2019 Apr 3.

UMR BIPAR, INRA, ANSES, Ecole Nationale Vétérinaire d'Alfort, Université Paris-Est, Maisons-Alfort, 94700, France.

This primer focuses on a recently diagnosed tick-borne allergic disease known as the alpha-Gal syndrome (AGS). Tick bites induce in humans high levels of IgE antibodies against the carbohydrate Galα1-3Galβ1-(3)4GlcNAc-R (α-Gal) present on tick salivary glycoproteins and tissues of non-catarrhine mammals, leading to the AGS in some individuals. This immune response evolved as a conflict and cooperation between ticks and human hosts including their gut microbiota. Read More

[Food Protein Induced Enterocolitis Syndrome due to ingestion of kiwi causing potentially severe unexplained event in a child].

Arch Argent Pediatr 2019 Apr;117(2):e178-e180

Área de Gestión de Pediatría, Hospital Universitario Central de Asturias, Oviedo, España.

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE food allergy manifesting as profuse, repetitive vomiting, sometimes with diarrhea, leading to dehydration and lethargy that can be severe and lead to shock. Despite the potential severity, awareness of FPIES is low and diagnosis is often delayed, especially in those triggered by solid foods. Presence of vomits and duration of more than 1 minute are the key differential factors to distinguish FPIES from brief resolved unexplained events. Read More

Immunotherapeutic Potential of Mollusk Hemocyanins in Combination with Human Vaccine Adjuvants in Murine Models of Oral Cancer.

J Immunol Res 2019 20;2019:7076942. Epub 2019 Jan 20.

Fundación Ciencia y Tecnología para el Desarrollo (FUCITED), Avenida Alcalde Eduardo Castillo Velasco 2902, Santiago, Chile.

Mollusk hemocyanins have been used for decades in immunological and clinical applications as natural, nontoxic, nonpathogenic, and nonspecific immunostimulants for the treatment of superficial bladder cancer, as carriers/adjuvants of tumor-associated antigens in cancer vaccine development and as adjuvants to dendritic cell-based immunotherapy, because these glycoproteins induce a bias towards Th1 immunity. Here, we analyzed the preclinical therapeutic potential of the traditional keyhole limpet hemocyanin (KLH) and two new hemocyanins from (CCH) and (FLH) in mouse models of oral squamous cell carcinoma. Due to the aggressiveness and deadly malignant potential of this cancer, the hemocyanins were applied in combination with adjuvants, such as alum, AddaVax, and QS-21, which have been shown to be safe and effective in human vaccines, to potentiate their antitumor activity.

Allison A Eddy

Pediatr Nephrol 2019 Feb 28. Epub 2019 Feb 28.

Department of Pediatrics, University of British Columbia and BC Children's Hospital Research Institute, Vancouver, Canada.

More than 250 drugs carry a small but important dose-independent risk of initiating a delayed-type hypersensitivity reaction that leads to acute tubulointerstitial nephritis (TIN). Clinical manifestations are often non-specific, making epidemiological studies challenging. In severe cases, if cessation of the offending drug is not followed by a prompt improvement in renal function, corticosteroid therapy appears to enhance renal recovery rates. Read More

Calcium-dependent, non-apoptotic, large plasma membrane bleb formation in physiologically stimulated mast cells and basophils.

J Extracell Vesicles 2019 20;8(1):1578589. Epub 2019 Feb 20.

Laboratory of Immunology and Signal Transduction, Chaminade University, Honolulu, Hawai'i.

Large membrane derangements in the form of non-detaching blebs or membrane protrusions occur in a variety of cell stress and physiological situations and do not always reflect apoptotic processes. They have been studied in model mast cells under conditions of cell stress, but their potential physiological relevance to mast cell function and formation in primary mast cells or basophils have not been addressed. In the current study, we examine the large, non-detaching, non-apoptotic, membrane structures that form in model and primary mast cells under conditions of stimulation that are relevant to allergy, atopy and Type IV delayed hypersensitivity reactions.

Adverse reaction to metal debris after small-head diameter metal-on-metal total hip arthroplasty: an increasing concern.

Hip Int 2018 Nov;28(2_suppl):35-42

3 IRCCS Istituto Ortopedico Galeazzi, Hip Department, Milan, Italy.

Introduction:: Failures due to adverse reaction to metal debris (ARMD) have become an area of common focus among surgeons performing hip replacements. Several authors have reported data on the prevalence of these masses, in both symptomatic and asymptomatic patients after either large-diameter head metal-on-metal (MoM) total hip arthroplasty (THA) or hip resurfacing arthroplasty, with a large variability of rate. To our knowledge, few data are reported on the association of this lesion with the use of small-head diameter MoM. Read More

Skin tests are important in children with β-lactam hypersensitivity, but may be reduced in number.

Pediatr Allergy Immunol 2019 Feb 7. Epub 2019 Feb 7.

Allergy Unit, Département de Pneumologie et Addictologie, Hôpital Arnaud de Villeneuve, CHU de Montpellier, Univ Montpellier, Montpellier, France.

Background: There is no perfect agreement on how to perform an allergy workup in suspected beta-lactam (BL)-allergic children, since skin test (ST)-induced pain is often a limitation. The aim of the study was to assess the possibility of reducing the number of ST in children when performing a complete allergy workup for BL hypersensitivity reactions.

Methods: A retrospective analysis of all patients referring to the Allergy Unit of the University Hospital of Montpellier (France) with positive responses in immediateand non-immediate-reading ST to a BL over a 16-year period was performed, to determine the positive predictive value (PPV) of ST.

The Inflammatory Effects of Breast Implant Particulate Shedding: Comparison With Orthopedic Implants.

Aesthet Surg J 2019 Jan;39(Supplement_1):S36-S48

Department of Orthopedic Surgery, Rush University Medical Center, Chicago, IL.

Currently, there is a dearth of information regarding the degree of particle shedding from breast implants (BIs) and what are the general biological consequences of BI debris. Thus, it is unclear to what degree BI debris compromises the long-term biological performance of BIs. For orthopedic implants, it is well established that the severity of biological reactivity to implant debris governs long-term clinical performance. Read More

Operational immune tolerance towards transplanted allogeneic pancreatic islets in mice and a non-human primate.

Diabetologia 2019 May 31;62(5):811-821. Epub 2019 Jan 31.

Diabetes Research Institute and Cell Transplant Center, University of Miami Miller School of Medicine, 1450 NW 10th Ave, Miami, FL, 33136, USA.

Aims/hypothesis: Patients with autoimmune type 1 diabetes transplanted with pancreatic islets to their liver experience significant improvement in quality of life through better control of blood sugar and enhanced awareness of hypoglycaemia. However, long-term survival and efficacy of the intrahepatic islet transplant are limited owing to liver-specific complications, such as immediate blood-mediated immune reaction, hypoxia, a highly enzymatic and inflammatory environment and locally elevated levels of drugs including immunosuppressive agents, all of which are injurious to islets. This has spurred a search for new islet transplant sites and for innovative ways to achieve long-term graft survival and efficacy without life-long systemic immunosuppression and its complications.

Sex Differences in Mouse Popliteal Lymph Nodes.

Sci Rep 2019 Jan 30;9(1):965. Epub 2019 Jan 30.

Division of Biomedical Sciences, School of Medicine, University of California, Riverside, Riverside, CA, 92521, USA.

Females have more robust immune responses than males, well-illustrated by the degree of inflammation elicited during delayed-type hypersensitivity (DTH) responses. Here, we have investigated underlying sex differences that may contribute to differential footpad DTH responses using wildtype and four core genotypes (FCG) mice and popliteal lymphnode cellularity and gene expression. DTH responses in XX and XY FCG females showed no role for almost all genes expressed on sex chromosomes. Read More
