Abstract:
A 66-year-old female kidney transplant recipient presented to Shanghai Jiao Tong University Affiliated Renji Hospital on May 24th, 2024 due to recurring intermittent diarrhea for over 16 years. The parasites were found through examination of small intestinal fluid. Small intestinal fluid mNGS combined with blood mNGS confirmed Cyclospora cayetanensis infection. The cause of the diarrhea was clarified. Oral compound sulfamethoxazole was used as treatment, and the patient's diarrhea symptoms improved, and no Cyclospora cayetanensis was found in the small intestinal fluid smear three consecutive times. Parasitic infection factors should be excluded in patients with low immune function and chronic diarrhea. Non-invasive small intestinal fluid smear combined with mNGS detection provides a new method to clarify the cause of chronic diarrhea.
