Clinical Manifestations of Compsobuthus persicus Scorpion Envenomation in Southern Iran

Background:Compsobuthus persicus scorpion is endemic to Iran and exists in Hormozgan, Bushehr and Fars provinces. The aim of this study was to assess the clinical manifestations of envenomation by C. persicus and the effect of its venom on the biochemical, hematological, and urinalysis parameters of the stung patients. Methods: In this analytical and retrospective study, all medical charts of patients who had been stung by C. persicus and admitted to the Emergency Departments of Shahid Mohammadi and Children Hospitals of Bandar Abbas, Iran, between May 2014 and November 2015 were assessed. Data from the patients’ test results were recorded including age, gender, clinical manifestations, urinalysis, blood chemistry, and complete blood cell count (CBC). Results: A total of 275 cases of scorpion stinging were assessed. Of them, 55 cases consisting of 28 males (50.9%) and 27 females (49.1%) at ages of 2 to 57 years old had been stung by C. persicus. Localized pain was the most frequent presenting patients’ complaint (90%). The most frequent symptom reported was vertigo (70%). However, the results of the urinanalysis, biochemical, and hematological parameters of the blood samples were in normal ranges. Conclusions: The severity of venom poisoning by C. persicus was mild and the biochemical and hematological parameters of the patients’ blood and urinalysis were within normal ranges, and there is no need for antivenin administration.
