Diagnosing and Treating Cryptogenic Organizing Pneumonia (COP)
COP (formerly called BOOP) is a rare disease of unknown cause. It is usually diagnosed by ruling out other diseases. Sometimes the signs, symptoms, X-ray and biopsy findings of COP may occur as side effects of medications. It is essential to determine whether the condition is caused by a medication because stopping that treatment will help to treat the disease.
What to Expect
Your doctor will ask you many questions about your health to get a detailed patient history. He or she will also most likely have you undergo several tests before a diagnosis is given.
How COP Is Diagnosed
A diagnosis of COP will usually include a clinical evaluation, a detailed patient history and identification of characteristic findings. Your health provider may also order specialized tests such as chest X-rays, laboratory tests, pulmonary function tests, and possibly a lung biopsy.
How COP Is Treated
Sometimes COP will go away on its own; however, in most cases some form of treatment is necessary. The treatment of choice is corticosteroids, such as prednisone. Cytotoxic drugs such as cyclophosphamide may be used to treat COP if there is no improvement with corticosteroid treatment.
It is important to note that COP is not responsive to antibiotic treatment.
