Pаget diseаse оf bоne (аlsо known as osteitis deformans) is characterized by high bone turnover and disorganized bone formation. The disease may involve one bone (monostotic) or multiple bones (polyostotic), with the latter being more common. The affected bone will initially have increased osteoclast activity causing lytic lesions throughout, then increased osteoblastic activity occurs, where bone is formed in a disorganized fashion. The high bone turnover results in highly vascular, weak, and deformed bones. Paget disease of bone is the second most common bone disease after osteoporosis and is common in patients over the age of 55 years. The cause of this disease is unknown, but a significant number of cases are genetic and passed on as an autosomal dominant trait. Patients with this condition are often asymptomatic or have mild symptoms. The bones most commonly affected are the pelvis, vertebrae, femur, humerus, and skull. Patients often report an aching, deep pain that is worse at night as the first symptom. This disease typically affects the bones proximally and then advances distally. Patients may also report arthritic pain if the adjacent joints are involved. Due to the disorganized bone turnover, bones can be soft, leading to bowed tibias, kyphosis, and easy fractures with light trauma. Patients with skull involvement may report increased hat size, headaches, or dilated scalp veins. If the temporal bone is involved, the cochlea can be damaged, leading to mixed sensorineural and conductive hearing loss, tinnitus, and vertigo. Laboratory findings will reveal a markedly elevated serum alkaline phosphatase, although patients with monostotic disease may have a normal level. In patients with normal serum alkaline phosphatase levels, a bone-specific alkaline phosphatase should be ordered, which will be high to distinguish an elevated phosphatase from bone as opposed to the liver. Other markers for bone turnover are serum N-terminal propeptide of type I collagen and serum beta C-terminal propeptide of type I collagen. If the patient is on bed rest, serum calcium may be elevated. A serum 25-OH vitamin D level should also be obtained to rule out vitamin D deficiency, which can also present with increased alkaline phosphatase in the presence of bone pain. Radiographs will reveal osteolytic lesions of the affected bones with focal radiolucencies or advancing flame-shaped lytic lesions. Bones may become sclerotic as well. Technetium-99m pyrophosphate bone scans may be helpful to determine the activity of bone lesions even before they appear on radiographs. Since most patients have mild disease or are asymptomatic, they are typically diagnosed incidentally during radiologic imaging or because of an elevation of alkaline phosphatase on a routine blood test. Treatment depends on the symptomaticity and severity of the disease. Asymptomatic patients may only require routine follow-up without treatment. However, even those who are asymptomatic but have significant long bone, skull, or vertebral involvement should be treated, closely monitored for serial serum alkaline phosphatase levels, and receive regular physical examinations. The mainstay of treatment for Paget disease is bisphosphonates, with intravenous zoledronic acid as the treatment of choice, which has been shown to normalize serum alkaline phosphatase levels in most patients within the first 2 years. Prognosis of this disease is good, but relapse can occur. Therefore, patients must be monitored long-tern with yearly serum alkaline phosphatase measurements.
