Peachy sputum is a common clinical manifestation of pulmonary schistosomiasis. Lung schistosomiasis, also known as pulmonary schistosomiasis, is an acute or chronic endemic parasitic disease caused by Schistosoma haematobium. The parasites are mainly found in the lungs, with cough and peachy sputum as the main manifestations, but also in various tissues and organs, such as the brain, spinal cord, gastrointestinal tract, abdominal cavity and subcutaneous tissue, producing corresponding symptoms. The clinical manifestations are also diverse. The incubation period is a few days to 20 years, mostly within 1 year. What are the examination methods of rotten peach-like blood sputum? 1, pathogenic diagnosis 1) Sputum or fecal egg examination: finding and colonizing the eggs of trematodes can confirm the diagnosis. (2) Biopsy: surgical removal of subcutaneous masses or nodules may reveal child worms, or typical pathological changes. (3) Blood picture: total white blood cell count and eosinophil count are elevated. 2, immunological test (1) intradermal test: commonly used in census, positive compliance rate can be up to 95% or more, but there are often false positives and false negatives. (2) Enzyme-linked immunosorbent assay: high sensitivity, positive rate of up to 90% to 100%. (3) Circulating antigen detection: recent application of enzyme-linked immunosorbent antigen spot test (AST-ELISA) directly detects circulating antigen in serum, with a positive rate of more than 98%, and can be used as efficacy evaluation. 3.X-ray examination The lungs may have infiltration, cystic nodules and hard nodules shadow. Sometimes signs such as thickened pleural adhesions, pleural fluid, pneumothorax or hydropneumothorax are found. In most cases, there are mixed shadows in the lungs. In some cases, there is no abnormal X-ray examination, or there is only thickening of the middle and lower textures of both lungs. Regular radiographs should be taken before and after treatment for comparison. For brain type, cerebral angiogram and myelogram can be done to show the lesion site.
