BACKGROUND: Bee venom (BV) has been widely investigated for potential medical uses. Recent inadvertent uses of BV based products have shown to mitigate signs of fungal infections. However, the component mediating the antifungal effect has not been identified. OBJECTIVE: This investigation compares bee venom in its whole and partial forms to evaluate the possible component responsible for the antifungal effect. METHODS: Forty-eight plates inoculated with Trichophyton rubrum were allocated into four groups. The groups were treated with raw BV (RBV), melittin, apamin and BV based mist (BBM) respectively and each group was further allocated accordingly to three different concentrations. The areas were measured every other day for 14 days to evaluate the kinetic changes of the colonies. RESULTS: The interactions of ratio differences over interval were confirmed in groups treated with RBV and BBM. In RBV, the level of differences were achieved in groups treated with 10 mg/100 µl (p=0.026) and 40 mg/100 µl (p=0.000). The mean difference of ratio in groups treated with RBV was evident in day 3 and day 5. The groups that were treated with melittin or apamin did not show any significant interaction. In BBM groups, the significant levels of ratio differences over time intervals were achieved in groups treated with 200 µl/100 µl (p=0.000) and 300 µl/100 µl (p=0.030). CONCLUSION: The the bee venom in its whole form delivered a significant level of inhibition and we concluded that the venom in separated forms are not effective. Moreover, BV based products may exert as potential antifungal therapeutics.

Bee venom injection therapy is an alternative treatment sometimes used for chronic inflammatory diseases, including rheumatoid arthritis and multiple sclerosis, to reduce pain. Several chemical components of bee venom have anti-inflammatory effects, and apitoxin, one of the mixed components, has been used for pain prevention therapy. However, there have been no large-scale investigations regarding the efficacy or side effects or apitoxin. In this study, a case of serum sickness reaction that developed after receiving bee venom injection therapy is reported.

Bee venom immunotherapy (b-VIT) can be combined with omalizumab therapy in order to suppress systemic reactions developing due to b-VIT itself. Omalizumab acts as a premedication and gains time for the immunotherapy to develop its immunomodulatory effects. However, the combination of omalizumab and b-VIT is not always effective enough. Herein we present a patient in whom successful immunotherapy cannot be achieved with combination of omalizumab to b-VIT.

Bee stings can cause severe adverse reactions, leading to anaphylaxis, cardiovascular collapse, and death. In some cases, bee venom also induces disseminated intravascular coagulation (DIC). However, to our knowledge, there has been no fatal case of intravascular coagulation accompanied by anaphylaxis caused by bee sting acupuncture. Here, we report a fatal case of a 65-year-old woman with DIC, following anaphylactic shock after bee sting acupuncture. This case emphasizes that practitioners should consider anaphylaxis followed by coagulation abnormalities when a patient's vital signs are unstable after bee sting acupuncture.

BACKGROUND: Allergic reactions developing after bee sting can be severe and life-threatening. According to epidemiological data, serious systemic reactions range between 1.2%–3%, and this is 2–3 times higher (6%) in beekeeping. In different beekeepers' populations, risk factors of systemic reactions have been investigated and diverse results have been found. OBJECTIVE: The aim of this study is to evaluate the level of knowledge of beekeepers about venom allergy, epidemiological data, systemic reaction rates, risk factors for systemic reactions, and the rate of emergency admissions after bee sting. METHODS: With the collaboration of Uludağ University Beekeeping Development Research Center and Beekeepers Association, a questionnaire consisting of 19 questions was applied to 242 beekeepers in Bursa and Yalova. Two hundred twenty-one beekeepers who completed the questionnaire were involved in the study. RESULTS: The mean age of the beekeepers was 49.9 years (range, 18–75 years). The systemic reaction to bee sting in beekeepers was 37.6%. Allergic rhinitis was found to be a risk factor for systemic reaction. Although 80% of the beekeepers recognized that bee venom could be lethal, only 60% of the beekeepers were aware of immunotherapy, and only 30% were aware of the adrenaline auto-injector drug. CONCLUSION: Similar to previous studies, we found that the systemic response to the bee sting in beekeepers was higher compared to normal population. Considering the occupational exposure to bee venom and thus higher risk, the awareness of venom allergy in this high risk population was low, and they were poorly informed about the treatment options.

Bee venom (Apis mellifera L., BV) has been used as a cosmetic ingredient for antiaging, anti-inflammatory and antibacterial functions. The aim of this study was to access the skin sensitization of BV, a Buehler test was conducted fifty healthy male Hartley guinea pigs with three groups; Group G1 (BV-sensitization group, 20 animals), group G2 (the positive control-sensitization group, 20 animals), and group G3 (the ethyl alcohol-sensitization group, 10 animals). The exposure on the left flank for induction was repeated three times at intervals of one week. Two weeks after the last induction, the challenge was performed on the right flank. No treatment-related clinical signs or body weight changes were observed during the study period. The average skin reaction evaluated by erythema and edema on the challenge sites and sensitization rate in the BV-sensitization group at 30 hours were 0.0 and 0%, respectively, which are substantially low compared with in positive control group (average skin reaction: 0.55, sensitization rate: 40%) and identical with in vehicle control group, representing a weak sensitizing potential. The average skin reaction and sensitization rate observed at 54 hours were 0.0 and 0% in the BV-sensitization group, respectively, and 0.25 and 20% in the positive control group, respectively. It was concluded that BV classified to Grade I, induced no sensitization when tested in guinea pigs and may provide a developmental basis for a cosmetic ingredient or external application for topical uses.

Honeybee sting is an important problem because of their high incidence and ability to produce fatal anaphylactic reactions. They can also produce erythema and edema at the site of a sting in non-allergic individuals and extensive local reactions in allergic patients. Bee venom acupuncture has been widely used in Oriental medicine as pain control, however, its side effects are not well known. Only a few cases of anaphylaxis by bee venom acupuncture have been reported, but there is no case report of its delayed type skin reaction. We report a case of persistent delayed type skin reaction due to bee venom acupuncture.

Subcutaneous injection of bee venom causes long-term neural activation and hypersensitization in the dorsal horn of the spinal cord, which contributes to the development and maintenance of various pain-related behaviors. The unique behavioral 'phenotypes' of nociception and hypersensitivity identified in the rodent bee venom test are believed to reflect a complex pathological state of inflammatory pain and might be appropriate to the study of phenotype-based mechanisms of pain and hyperalgesia. In this review, the spinal processing of the bee venom-induced different 'phenotypes' of pain and hyperalgesia will be described. The accumulative electrophysiological, pharmacological, and behavioral data strongly suggest that different 'phenotypes' of pain and hyperalgesia are mediated by different spinal signaling pathways. Unraveling the phenotype-based mechanisms of pain might be useful in development of novel therapeutic drugs against complex clinic pathological pain.

Bee venom (Apis mellifera L. BV) has been used as a cosmetic ingredient for anti-ageing, anti-inflammatory and antibacterial functions. The aim of this study was to evaluate the acute toxicity after a single dermal administration of BV, BV was administered to 2 groups of Sprague-Dawley (SD) male and female rats (5 animals/group) at doses of 0 and 1,500 mg/kg body weight (BW). Mortality, clinical signs, body weight changes and gross findings were continually monitored for 15 days following the single dose. There were no unscheduled deaths in any groups during the study period. No BV related clinical signs and body weight changes were observed in any groups during the study period. There were no abnormal gross findings at necropsy on day 15 after the treatment. On the basis of the above results, it was concluded that there were no treatment-related effect on mortality, clinical signs, body weight changes and gross findings in SD rats treated with a single dermal dose of BV at dose of 1,500 mg/kg BW. Therefore, the approximate lethal dose of BV was considered to be over 1,500 mg/kg/day for both sexes of rats. BV may provide a developmental basis for a cosmetic ingredient or external application for topical uses.
