Bright's disease is a kidney disorder, according to MedicineNet. In Bright's disease, the blood vessels in the kidneys are inflamed and albumin, a type of protein, is excreted in the urine. Bright's disease is also known as nephritis and can be acute or chronic, says Wikipedia.
Acute nephritis comes about as a side effect of a drug or the patient having taken drugs such as NSAIDS for a long time, says MedlinePlus. It can also be an allergic reaction to a drug or a side effect of a drug such as penicillin or omeprazole. Bright's disease can come about because the levels of potassium in the patient's blood are too low or the levels of calcium or uric acid in the blood are too high.
Symptoms of Bright's disease are fever, nausea and vomiting, rash, swelling and weight gain from edema, claims MedlinePlus. The patient might need to urinate more frequently or less frequently than normal and may see blood in his urine. His mental state may also be disordered, and he might become drowsy or confused. In severe cases of Bright's disease, he could become comatose.
Treatment of Bright's disease can range from stopping certain medications to dialysis, says MedlinePlus.
