Paget’s disease, otherwise known as osteitis deformans, is a chronic disorder that typically results in enlarged and deformed bones. It is named after Sir James Paget, the British surgeon who first described this disease[1]. The excessive breakdown and formation of bone tissue that occurs with Paget’s disease can cause bone to weaken, resulting in bone pain, arthritis, deformities, and fractures. Paget’s disease may be caused by a slow virus infection (i.e., paramyxoviruses such as measles, Canine distemper virus[2], and respiratory syncytial virus), present for many years before symptoms appear. Most studies have pointed at either Canine distemper virus or Measles.[3][4][5] There is also a hereditary factor since the disease may appear in more than one family member.
Paget’s disease is rarely diagnosed in people less than 40 years of age. Men are more commonly affected than women. Prevalence of Paget’s disease ranges from 1.5 to 8 percent depending on age and country of residence. Prevalence of familial Paget’s disease (where more than one family member has the disease) ranges from 10 to 40 percent in different parts of the world.[citations needed]Because early diagnosis and treatment is important, after age 40, siblings and children of someone with Paget’s disease may wish to have an alkaline phosphatase blood test every two or three years. If the alkaline phosphatase level is above normal, other tests such as a bone-specific alkaline phosphatase test, bone scan, or x-ray can be performed.
Many patients do not know they have Paget’s disease because they have a mild case with no symptoms. Sometimes, symptoms may be confused with those of arthritis or other disorders. In other cases, the diagnosis is made only after complications have developed. Symptoms can include:
Paget’s disease may be diagnosed using one or more of the following tests:
The outlook is generally good, particularly if treatment is given before major changes in the affected bones have occurred. Any bone or bones can be affected, but Paget’s disease occurs most frequently in the spine, skull, pelvis, thighs, and lower legs. In general, symptoms progress slowly, and the disease does not spread to normal bones. Treatment can control Paget’s disease and lessen symptoms but is not a cure. Osteogenic sarcoma, a form of bone cancer, is an extremely rare complication that occurs in less than one percent of all patients.
Paget’s disease may lead to other medical conditions, including:
