INTRODUCTION: Although it is an essential component of the treatment of acute lymphoid leukemia in children, asparaginase causes adverse reactions that sometimes make it impossible to use it fully. Hypersensitivity reactions are the most frequent and may lead to early discontinuation of treatment. The present study aimed to investigate suspicions of adverse reactions during the infusion of asparaginase in a pediatric cohort. METHODS: A retrospective observational study was carried out at a university pediatric institute in the state of Rio de Janeiro...

An unusual fluorescent pseudomonad was isolated from tomato exhibiting leaf spot symptoms similar to bacterial speck. Strains were fluorescent, oxidase- and arginine-dihydrolase-negative, elicited a hypersensitive reaction on tobacco and produced a soft rot on potato slices. However, the strains produced an unusual yellow, mucoid growth on media containing 5 % sucrose that is not typical of levan. Based on multilocus sequence analysis using 16S rRNA, gap1, gltA, gyrB and rpoD, these strains formed a distinct phylogenetic group in the genus Pseudomonas and were most closely related to Pseudomonas viridiflava within the Pseudomonassyringae complex...

Sensitization and activation of the trigeminal ganglia have been implicated in the pathology of migraine. Satellite glial cells (SGCs), a specialized type of glial cells that ensheathe trigeminal neurons, may be critical for peripheral nociceptive sensitization. Tetrandrine (TET), an alkaloid extracted from a traditional Chinese herb, exerts an inhibitory effect on glial activation in vitro and has been used in various neurologic diseases. The current study investigated the effect of TET on nitroglycerin (NTG)-induced trigeminal sensitization and examined potential signaling pathways related to SGC activation in the model of migraine...

<p>Extravasation of medications can manifest as tenderness, pain, tissue necrosis, and thrombophlebitis and lead to infection and severe long-term complications. Risk factors for leakage of medications include mechanical and pharmacologic mechanisms such as cannulation technique, vasoconstriction, and cytotoxicity. Well-known vesicants like anthracyclines, vinca alkaloids, and vasopressors are usually administered with proper caution. Often overlooked are many antimicrobial agents, which typically act via differences in osmolality and pH...

A healthy 50-year-old woman had a tattoo performed on the posterior aspect of her neck and another on the dorsum of her left foot. Several weeks later, she noted redness, tenderness, and intense pruritis at both tattoo sites. Treatment with cephalexin and hydrocortisone cream was instituted, without success. Within a few months, the red, but not black, pigment had disappeared from both tattoos and was replaced by pale areas of scarring. Persistently enlarged left supraclavicular and suboccipital lymph nodes were excised 7 and 10 months after receipt of the tattoos, respectively...

BACKGROUND: Endobronchial valve (EBV) placement is an established lung volume reduction procedure aiming to improve lung function and exercise capacity in patients with severe emphysema. As EBVs consist of silicone and nitinol (a metal alloy of nickel and titanium), there are concerns that nickel ions might be released and could have a clinical impact in patients with a contact allergy to nickel. Based on a case with hypersensitivity pneumonitis (HP) after treatment with EBVs, we aimed to evaluate the in vitro nickel release from EBVs using inductively coupled plasma mass spectrometry (ICP-MS) and scanning electron microscopy (SEM)...

Virtually all therapeutic proteins (biologics) elicit an immune response with the consequent production of anti-drug antibodies (ADA). The majority of ADA to therapeutic monoclonal antibodies (mAbs) are directed against the antigen-binding site of the therapeutic mAb, and hence are neutralizing. This nature of the ADA response explains why fully human antibodies can still be highly immunogenic. The detection of ADA is technically challenging and all assays have limitations, namely a limited capacity in detecting ADA in the presence of a drug due to immune complex (IC) formation, which may underestimate the ADA incidence...

Myeloid-derived suppressor cells (MDSCs) possess the ability to suppress the immune response, and to amplify the regulatory properties of other immune cells, i.e., dendritic cells. Here we describe a protocol in which MDSCs were differentiated from murine bone marrow cells, and CD11c(+) dendritic cells were purified from murine spleens. MDSCs and CD11c dendritic cells can be co-cultured and the immunoregulatory phenotype of the MDSCs-conditioned dendritic cells could be assessed by means of a specific functional in vivo experiment, i...

Over the past decade, smoking behaviors have changed in the US. Hookah or waterpipe smoking is increasing, especially among youth and young adults. Social media sites describe the "hookah high" or "buzz", which may be related to nicotine, carbon monoxide, or other inhalants in hookah smoke. Most important is the risk of carbon monoxide poisoning. Case reports include a high number of victims presenting with loss of consciousness from either syncope or seizures. Anaphylaxis and a very rare respiratory hypersensitivity reaction, acute eosinophilic pneumonia, have also been reported from hookah smoking in previously healthy young adults...

Inhalational anthrax is a highly lethal infection caused by Bacillus anthracis and a serious bioterrorism threat. Protective antigen (PA) is a critical component required for the virulence of Bacillus anthracis. Obiltoxaximab, a high-affinity monoclonal antibody that neutralizes PA, is approved in the United States for intravenous use for the treatment of inhalational anthrax in combination with appropriate antibacterial drugs and for prophylaxis of inhalational anthrax when alternative therapies are not available or appropriate...

Serum sickness is a hypersensitivity reaction to proteins in antiserum derived from nonhuman animal sources and can be seen in patients being treated with antiserum to prevent transplant rejection. Serum sickness may display variable clinical presentations. Because cutaneous findings may be the initial symptom in some cases, it is important for dermatologists to be able to recognize this condition given its potentially life-threatening symptoms. We present a case of a 35-year-old man with presumed serum sickness after receiving thymoglobulin for the treatment of acute cellular rejection of a heart transplant...

The PhoPQ two-component regulatory system coordinates the response of Salmonella enterica serovar Typhimurium to diverse environmental challenges encountered during infection of hosts, including changes in Mg(2+) concentrations, pH, and antimicrobial peptides. Moreover, PhoPQ-dependent regulation of gene expression promotes intracellular survival of Salmonella in macrophages, and contributes to the resistance of this pathogen to reactive nitrogen species (RNS) generated from the nitric oxide produced by the inducible nitric oxide (NO) synthase of macrophages...

PEGylated asparaginase (pegaspargase) can be administered via intramuscular (IM) injection or intravenous (IV) infusion with a hypersensitivity reaction (HSR) incidence ranging 3-41%. We evaluated grade ≥3 HSRs when given IM vs. IV on six Children's Oncology Group (COG) leukemia trials (2003-2015) to determine differences in HSR rates. 54,280 doses were administered to 16,534 patients. Considering all doses of pegaspargase during induction, consolidation, and delayed intensification, grade ≥3 HSR rate with IM injection was 5...

In this study, the immunomodulatory activities of Apostichopus japonicus glycosaminoglycan (AHG) on the nature killer (NK) cells, cytotoxic T lymphocytes (CTLs) and cyclophosphamide (CY)-treated mice were investigated. After stimulation with multiple concentrations of AHG (0-100 μg/mL), NK cells and CTLs displayed outperformance against YAC-1 and B16 cells, respectively. Furthermore, the mitogen-induced splenic lymphocyte proliferation in CY-induced immunosuppressed mice was significantly promoted by AHG. In addition, the administration of AHG dramatically increased the splenocytes Ca(2+) concentration and the delayed-type hypersensitivity (DTH) reaction in a dose-dependent manner...

The chemical amaranth (AM) is permitted as a colouring agent in a variety of foods. Safety was established based on chronic rodent studies. AM and its metabolite naphthionic acid (NA) can be absorbed through the intestine, exposing circulating immune cells including splenocytes. An AM feeding study in rats demonstrated an increase in blood lymphocytes. Yet, in contrast, AM inhibited the delayed-type hypersensitivity reaction to antigen. DO11.10 mice express a T Cell Receptor specific for ovalbumin323-339 peptide (OVAp) presented by I-A(d) MHCII...

Adverse drug reactions of the delayed type rank among the most common dermatoses and are predominantly characterized by exanthematous macular or maculopapular eruptions. However, approximately 2 % of affected individuals develop severe or even life-threatening systemic immune reactions associated with organ involvement, requiring immediate diagnosis and treatment. Numerous drugs are capable of eliciting delayed-type hypersensitivity reactions, with antibiotics, anticonvulsant drugs, and the xanthine oxidase inhibitor allopurinol being the most common...

Drug hypersensitivity reactions (DHRs) represent growing health problem worldwide, affecting more than 7% of the general population and represent an important public health problem. However, knowledge in DHRs morbidity and mortality epidemiological data is still not optimal and international comparable standards remain poorly accessed. Institutional databases worldwide increasingly use the WHO International Classification of Diseases (ICD) system to classify diagnoses, health services utilization and death data...

Antipsychotic drugs are used to treat schizophrenia and other psychiatric disorders. However, most of these drugs present side effects causing obesity and other serious metabolic alterations that correlate with grade of chronic inflammation. In contrast, ziprasidone's (ZIP) metabolic side effects are attenuated relative to those of other antipsychotic drugs, but some reports suggest that this drug could cause allergic, hypersensitive reactions in susceptible patients. At present, the mechanism of ZIP's effect on peripheral inflammatory metabolism is not well characterized...
