The positive effect of spermidine in older adults suffering from dementia after 1 year.

Background: A positive effect of the effect of a 3-month oral spermidine intake on memory performance has already been demonstrated. The continuation of this study aimed to examine whether there could be observed an improvement in memory performance after one year.

Method: 45 residents of the nursing home "Gepflegt Wohnen" in Hart bei Graz, Styria, Austria, were given a daily dose of 3.

The positive effect of spermidine in older adults suffering from dementia : First results of a 3-month trial.

The worldwide prevalence of dementia is estimated at 35.6 million and will rise to 115 million by 2050. There is therefore an urgent need for well-founded dementia diagnostics and well-researched therapeutic options.

Drug-specific history, skin and in vitro tests can reduce the need for drug provocation tests in betalactam-hypersensitivity.

Background: Many patients report questionable drug hypersensitivity reactions (DHR) to betalactam antibiotics. A workup is required for objectivation. Direct drug provocation tests (DPTs) omitting a prior allergy workup are increasingly recommended as the primary diagnostic approach.

Spermidine in dementia : Relation to age and memory performance.

Previous studies have highlighted that spermidine has the ability to trigger the important process of dissolving amyloid-beta plaques by autophagy. This manuscript focuses on the correlation of serum spermidine levels between age and between performance in mini-mental state examinations. It will serve as a premise for an ongoing multicentric placebo-controlled study, which focuses on the effect of oral spermidine supplementation on memory performance.

Allergic patients with and without allergen-specific immunotherapy mount protective immune responses to tick-borne encephalitis vaccination in absence of enhanced side effects or propagation of their Th2 bias.

Background: Allergic diseases are caused by Th2-driven immune responses and their treatment with specific immunotherapy (SIT) leads to immunomodulation via IL10, TGF-ß and Th1/Tr1 shift. This phase IV, open-label clinical trial investigated whether allergies and SIT treatment influenced immune responses to routine vaccination.

Methods: We studied three groups: 49 allergic patients (allergic group), 21 allergic patients receiving maintenance doses of SIT (SIT group), and 49 non-allergic controls.

Clinical characteristics and risk profile of patients with elevated baseline serum tryptase.

Background: The clinical relevance of elevated basal serum tryptase (eBST ≥ 11.4 ng/ml) often remains unclear.

Methods: BST was assessed in 15,298 patients attending our outpatient clinic.

Impact of oral vitamin C on histamine levels and seasickness.

Background: Seasickness is a risk aboard a ship. Histamine is postulated as a causative agent, inversely related to the intake of vitamin C. Persons with mastocytosis experienced improvement of nausea after the intake of vitamin C.

Risk of anaphylaxis in opioid dependent persons: effects of heroin versus substitution substance.

Background: Across Europe, illicit drug-related mortality has not declined despite ever increasing prevention measures. The cause of these deaths has traditionally been associated with overdose. Previous findings have revealed the appearance of non-lethal opioid concentrations, leading us to investigate a further cause of death.

[Abdominal spasms, meteorism, diarrhea: fructose intolerance, lactose intolerance or IBS?].

Meteorism, abdominal spasms, diarrhea, casually obstipation, flatulence and nausea are symptoms of fructose malabsorption (FIT) and/or lactose intolerance (LIT), but are also symptoms of irritable bowel syndrome (IBS). Therefore these diseases should be considered primarily in patients with digestive complaints. For diagnosis an H(2)-breath test is used.

Thioredoxin from the Indianmeal moth Plodia interpunctella: cloning and test of the allergenic potential in mice.

Background/objective: The Indianmeal moth Plodia interpunctella is a highly prevalent food pest in human dwellings, and has been shown to contain a number of allergens. So far, only one of these, the arginine kinase (Plo i 1) has been identified.

Objective: The aim of this study was to identify further allergens and characterise these in comparison to Plo i 1.

Usefulness of post mortem determination of serum tryptase, histamine and diamine oxidase in the diagnosis of fatal anaphylaxis.

The diagnosis of fatal anaphylaxis can be difficult for clinical features may not always be evident in necropsy. Therefore post mortem determination of tryptase and other blood parameters can be helpful in verifying the diagnosis. We compared post mortem tryptase, histamine and diamine oxidase (DAO) serum levels of two patients who had died after a Hymenoptera sting and one patient who died of bronchospasm during anaesthesia with data obtained from 55 control subjects who had died from other causes than anaphylaxis.

Persistence of antibodies in 4-8 year old Austrian children after vaccination with hexavalent DTaP-HBV-IPV/Hib and MMR vaccines.

To determine the proficiency of the Austrian childhood vaccination schedule to induce long lasting seroprotection against vaccine preventable diseases a seroepidemiological study in 348 children between four and eight years of age was conducted. Antibodies against diphtheria, tetanus, pertussis, hepatitis B, measles, mumps and rubella antigens were assessed in children, who had been vaccinated with hexavalent DTaP-HBV-IPV/Hib vaccines at three, four, five months and in the second year of life and/or MMR vaccines in the second year of life at least once, but mostly twice. High seroprotection rates (SPRs) were detected for tetanus (96%) and measles (90%).

Levels of histamine and other biogenic amines in high-quality red wines.

Biogenic amines in wine may impair sensory wine quality and cause adverse health effects in susceptible individuals. In this study, histamine and other biogenic amines were determined by HPLC after amine derivatisation to dansyl chloride conjugates in 100 selected high-quality red wines made from seven different cultivars. Amine levels varied considerably between different wines.

[Jellyfish and poison-producing animals that endanger swimmers].

Exposure to fresh water as well as to sea water can cause unpleasant consequences. The water of lakes or biotopes may be the reason for severe itching reactions on exposed skin, caused by cercariae. Exposure to seawater may lead to skin affections including itching or burning urticarial lesions as well as life threatening reactions.

Identification of Bet v 1-related allergens in fig and other Moraceae fruits.

Background: Allergy to fig fruit (Ficus carica) has been described in patients allergic to Ficus benjamina or rubber latex but may occur also in pollen-allergic patients.

Objective: To study the potential cross-reactivity between fig and taxonomically related fruits with the major birch pollen allergen Bet v 1.

Methods: One hundred and eighty-eight patients with or without birch pollen allergy were prick-to-prick tested with fig (F.

Uncombable hair and atopic dermatitis in a case of trichodento-osseous syndrome.

The tricho-dento-osseous syndrome is a rare genetic disorder due to a mutation in the DLX3 gene on chromosome 17q21. It can affect hair, teeth, bone and nails, causing phenotypic variability. We report on an 8-year-old girl with tricho-dento-osseous syndrome, who presented in our allergy center with severe atopic dermatitis.

Reassessing the role of hyaluronidase in yellow jacket venom allergy.

Background: Yellow jacket hyaluronidase (YJ-HYA) is considered a major allergen in yellow jacket allergy. It shows 50% homology with the hyaluronidase from honeybee venom, Api m 2. Recently, IgE binding to YJ-HYA and cross-reactivity with Api m 2 has been shown to be due to cross-reactive carbohydrate determinants (CCDs).

Exogenous histamine aggravates eczema in a subgroup of patients with atopic dermatitis.

Food and beverages may contain high amounts of histamine and thus may cause symptoms after ingestion. The aim of this study was to investigate the role of ingested histamine in atopic dermatitis. Patients with atopic dermatitis had to maintain a histamine-free diet for one week.

Exercise with latex sport bands represents a risk for latex allergic patients.

Based on two clinical observations of adverse reactions during exercise with latex sport bands, we aimed to assess the possible risk for allergic patients posed by this equipment by investigating allergen content and IgE binding potential. Protein extracts of three different latex sport bands were characterized with sera of latex allergic patients. The IgE recognition profile of the allergic patients was identified by component resolved diagnosis and the allergen composition of the extracts was characterized by inhibition assays with the recombinant latex allergens Hev b 1, 3, 5, 6.
