The zoonotic role of Cryptosporidium has also made it important in terms of economics and public health. Cryptosporidium is one of the most important common intestinal pathogens that has been reported in many organisms and in most parts of the world. Tyzzer first reported this protozoan in 1907 from the stomach glands of a laboratory mouse. don’t role in urticaria.Ĭryptosporidiosis is one of the protozoan diseases caused by coccidia of the genus Cryptosporidium.
Therefore, our result may be evidence for the role of this parasite in the development of urticaria if other causes such as food allergies, autoimmune diseases and etc. ConclusionĪ number of parasites are associated with urticaria, but to our knowledge, there is no information on Cryptosporidium-induced urticaria. The child was observed to produce < 3 loose stools in the previous 24 h after 1-week post-treatment and after 6 months of follow-up. The patient was successfully treated with nitazoxanide (100 mg twice daily) and became negative for parasites three days after treatment and one week after discharge from the hospital. Several Cryptosporidium oocysts were detected in the modified acid-fast staining of the child’s stool sample. Since the child’s father worked in livestock farming, the parasite may have been transferred from the cow or calve to the house and the child. The patient had moderate diarrhea (> 3 loose, watery stools but not more than 10 diarrhea stools in a day), weight loss, and acute urticarial (rash clears completely within 6 weeks). We report a case of urticaria associated with Cryptosporidium in a 17-month-old female Iranian child.
In immunocompromised patients and children under 5 years of age, the infection is severe and can be life-threatening due to severe diarrhea. Cryptosporidium is an intracellular protozoan that causes gastrointestinal symptoms in humans and animals.
