What are symptoms of Churg-Strauss syndrome?
Churg-Strauss syndrome causes fever, weight loss, and sinus or nasal passage inflammation in the patient with asthma. Fatigue is common. Sometimes the asthma actually improves somewhat as the disease intensifies elsewhere. Cough, shortness of breath, and chest pain can occur as the lungs are affected by vasculitis.
Skin lumps, called nodules, can appear on the extremities. Diarrhea and pain in the belly occur due to blood vessel inflammation within the abdomen. The bladder and prostate gland can become inflamed.
How is Churg-Strauss syndrome diagnosed?
Churg-Strauss syndrome is suggested when the symptoms described above occur in a patient with a history of asthma.
Abnormalities of the lungs, skin, and nerves might be noted by the doctor during the examination. Blood pressure can be elevated.
Blood examination generally shows elevated levels of an uncommon white blood cell, called an eosinophil, and other white blood cells are also elevated in number. Kidney function blood tests and urinalysis can be abnormal when the kidneys are affected (which is not common).
The ultimate test for the diagnosis is a biopsy of involved tissue, which demonstrates a characteristic pattern of inflammation visible under a microscope. Eosinophil are also seen accumulated in the abnormal tissue.
