Association between urticaria and virus infections: A systematic review

2016

Background The association between urticaria and virus infections has rarely been reported in the literature. The lack of reported cases is probably due to the difficulty in establishing a cause-and-effect relationship. It is not possible to challenge the patient with an etiologic agent. Objective The purpose of this work was to perform a systematic review on the association between urticaria and virus infections. Methods This systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched for articles from January 1, 2008, through May 2015, by using two key terms related to urticaria and virus diseases, "urticaria" and…

D-dimer concentrations in acute urticaria in children

2021

Introduction: Urticaria is a clinical entity presenting as wheals, angioedema, or both simul-taneously. Elevated D-dimer levels were reported in the course of chronic spontaneous urticaria. Data regarding D-dimer levels in acute urticaria in children are limited. Objectives: To assess potential associations between duration of glucocorticosteroid (GCS) therapy and D-dimer concentrations in children with acute urticaria. Patients, materials, and methods: Hospital records of 106 children (59 females), aged 5.57 ± 4.91 years, hospitalized in 2014–2018 were analyzed retrospectively. The study group consisted of pediatric patients admitted to the hospital due to severe acute urticaria resistant …

A Popular myth - low-histamine diet improves chronic spontaneous urticaria - fact or fiction?

2016

Background Chronic spontaneous urticaria (CsU) is a frequent dermatological disease that might last for months or years with high impact on quality of life. Known causes are autoreactive phenomena, infections or intolerances, rarely IgE-mediated allergies. One third of CsU patients benefit from a low-pseudoallergen diet. Additionally, it is often discussed, that reducing histamine ingestion alone might improve clinical symptoms and quality of life in CsU-patients despite the uncertain role of the histamine-degrading enzyme diamine oxidase (DAO). Objective Aim of this study is to investigate the impact of low-histamine diet on symptoms and quality of life in patients with CsU. Methods Patien…

Epidemiology of urticaria in German children

2020

Background To date, robust epidemiological metrics as well as data on comorbidity in pediatric urticaria are lacking. They form the basis for the design of efficient healthcare. Methods Retrospective study to analyze epidemiological data in pediatric urticaria. The analysis is based on routine data of a health insurance company operating throughout Germany (DAK-Gesundheit). Insured people under 18 years of age who received at least one confirmed outpatient or inpatient urticaria diagnosis according to the ICD-10 classification in the years 2010 to 2015 were included in the analysis and compared to children without a corresponding diagnosis. Results Of 2.3 million insured individuals, 313,58…

Leucine Aminopeptidase Activity in Mast Cells

1959

DURING investigations of the behaviour of leucine aminopeptidase activity of blood-serum in patients with dermatoses and tumours1–3, in a case of diffuse skin mastocytosis of a new-born, we detected heightened activity of leucine aminopeptidase. After mechanical friction of the affected skin, greater activity of leucine aminopeptidase occurred. From this we supposed a release of leucine aminopeptidase from the mast cell infiltrates of the skin. As is well known, in urticaria pigmentosa mechanical irritation of the skin lesions give rise to a degranulation of mast cells4,5 with liberation of histamine and serotonin. Indeed, there is no doubt that mast cells contain the enzyme leucine aminope…

Medicinal Plants from Near East for Cancer Therapy.

2017

Background: Cancer is one of the major problems affecting public health worldwide. As other cultures, the populations of the Near East rely on medicinal herbs and their preparations to fight cancer. Methods: We compiled data derived from historical ethnopharmacological information as well as in vitro and in vivo results and clinical findings extracted from different literature databases including (PubMed, Scopus, Web of Science, and Google Scholar) during the past two decades. Results: In this survey, we analyzed the huge amount of data available on anticancer ethnopharmacological sources used in the Near East. Medicinal herbs are the most dominant ethnopharmacological formula used among ca…

Biological parameters of Neoseiulus longilaterus (Athias-Henriot) (Parasitiformes, Phytoseiidae) fed on prey and pollen in laboratory conditions

2019

Tetranychus urticae is the most important pest on different crops worldwide. Search for endemic phytoseiid mites co-occurring with the above pest, which might be good candidates as biocontrol agents, represents the policy followed by most scientists in recent years. The aim of the present work was to assess the various biological and demographic parameters of Neoseiulus longilaterus, associated with T. urticae on weeds, in laboratory conditions using the latter tetranychid and pollen of Oxalis pes-caprae as food. The results showed a better performance of the predator on the prey as regards the postembryonic development (7.63 and 8.18 days for prey and pollen respectively) and the demograph…

The global burden of chronic urticaria for the patient and society*

2020

Chronic urticaria (CU) affects about 1% of the world population of all ages, mostly young and middle-aged women. It usually lasts for several years (> 1 year in 25-75% of patients) and often takes > 1 year before effective management is implemented. It presents as chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU) or both in the same person. More than 25% of cases are resistant to H1 -antihistamines, even at higher doses, and third- and fourth-line therapies (omalizumab and ciclosporin) control the disease only in two-thirds of H1 -antihistamine-resistant patients. Here we review the impact of CU on different aspects of patients' quality of life and the burden of this …
