OBJECTIVE To observe the effect of methylprednisolone (MP) plus adrenaline to treat patients injured by wasp stings. METHODS This study was carried out at The First College of Clinical Medical Science, China Three Gorges University, Yichang, Hubei Province, China, from June to November 2008. A total of 45 cases were divided into 2 groups. The MP was used alone in the control group, and MP plu...

BACKGROUND The aim of this study was to analyze the frequency of clinical features and the severity of systemic reactions to wasp stings, and to establish their relationship with mean age, sex, and atopy. METHODS We studied 115 patients who suffered an anaphylactic reaction to wasp sting and showed specific IgE to venoms from Vespula and/or Polistes. In all patients, age, sex and personal his...

OBJECTIVE To study the relationship between the primary sensitization to wasp venoms and the geographical and seasonal circumstances of the anaphylaxis-induced sting. METHODS We performed a retrospective review of 115 patients (age 10-80) who suffered a systemic reaction to a wasp sting. Season and type of locality (urban or rural) at the moment of the sting were recorded. Serum specific IgE ...

It has been reported that Paulistine in the venom of the wasp Polybia paulista co-exists as two different forms: an oxidized form presenting a compact structure due to the presence of a disulfide bridge, which causes inflammation through an apparent interaction with receptors in the 5-lipoxygenase pathway, and a naturally reduced form (without the disulfide bridge) that exists in a linear confo...

 Wasp sting is a relatively common arthropod assault. This usually results in pain and mild allergic reactions, but sometimes may cause severe systemic reaction and multiorgan dysfunction including rhabdomyolysis, hemolysis, coagulopathy, hepatic, renal and cardiac complications. Along with several other pathomechanisms, rhabdomyolysis is a distinguished cause of acute kidney injury (AKI) in pa...

Background Double sensitization to both honeybee (Apis mellifera) and Yellow Jacket (Vespula ssp.) venom is common in up to 59% of Northern European Hymenoptera venom allergic patients and this rate is more than 50% in the United States. In Brazil yellow jacket is not a common wasp, but Polistes sp. and Polybia paulista poses the major risk for Brazilian patients. Reports about double sensitiza...
