Abstract:

A 19-year-old male patient of Nigerian nationality, an international student of a university in Wenzhou, came to Wenzhou International Travel Healthcare Centre for entry medical examination on October 23, 2023, and reported no symptoms of discomfort. The blood routine test showed an increased percentage of eosinophils (15.9%), and the serum immunoglobulin test showed elevated levels of IgM antibodies (2.37 g/L). The urine routine test showed positive occult blood (2 +), positive protein (1 +), and elevated counts of both red blood cells (360 RBCs per μl) and white blood cells (255 WBCs per μl). Schistosoma haematobium eggs were found in the urine sediment by microscopy, and miracidia were hatched from the eggs. Nucleic acid testing of the urine sediment confirmed a positive result for S. haematobium. The B-ultrasonic showed slight thickening of the bladder wall. Epidemiological investigation suggested that the patient might have been exposed to contaminated water while swimming in lakes in Nigeria. Based on laboratory examination and epidemiological investigation, the patient was diagnosed as imported schistosomiasis haematobia. On October 27, the patient took orally praziquantel, 30 mg/(kg·d), 3 times a day for 2 consecutive days. A follow-up examination on November 13 revealed no eggs in the urine sediment.
