Background: Parasite infections stimulate total and specific IgE production that, in the case of infection, corresponds to chronic allergic symptoms. There may also be other infections which have similar symptoms, such as infection. is a large nematode that causes abdominal pain, nausea, vomiting, bloating, anorexia and intermittent diarrhoea.

Introduction: From the literature, patients with a history of anaphylaxis to hymenoptera venom and positive specific IgE have shown a correlation between elevated tryptase levels and two clinical situations: systemic mastocytosis and an increased risk of reactions to venom immunotherapy or hymenoptera sting. Other clinical scenarios could explain elevated tryptase levels.

Material And Methods: A 67 year old male (P1) and a 77 year old male (P2) were evaluated for previous severe anaphylaxis to hymenoptera sting.

Infection from Toxocara species may give rise to a large array of clinical symptoms, including apparent manifestations of allergy such as asthma, urticaria/angioedema, and dermatitis. We report a case, thus far not described, of contact dermatitis attributed to nickel allergy but caused by Toxocara infection. The patient was a 53-year-old woman presenting from 10 years a dermatitis affecting head, neck, and thorax.

Background: Toxocara canis is an intestinal nematode affecting dogs and cats, which causes human infection when embryonated eggs excreted in dog feces are ingested. Humans are paratenic hosts. Although the larvae do not develop into adult worms in the human body, they may migrate to various tissues and organs where they can survive for several years, giving rise to several clinical symptoms, which can present in allergy-like form.

Introduction: The efficacy of venom immunotherapy (VIT) in patients with insect sting allergy is not questioned. However, its safety, especially when honeybee is used, is a matter of concern.

Areas Covered: A systematic review of the literature on VIT was done, with both aqueous and depot extracts, to compare the frequency of systemic reactions to honeybee and vespid venoms.
