Does Paget's disease exist in India?
Paget's disease of bone has been described as a few case reports from India. The aim of the present study is to document the existence of Paget's disease (PD) in India. We describe demography, clinical manifestations, biochemical and radiological profile and the treatment outcome of 21 patients of PD. Mean (+/-SD) age of these patients at presentation was 49.2 +/- 17.6 years and the male to female ratio was 2.5:1. Common clinical manifestations included backache, headache and bone pains. Others were fracture, joint pain, deafness, gait ataxia, visual impairment and difficulty in biting. Two patients presented with hydrocephalus and one had recurrent paraparesis. Fifteen (71.4%) patients had polyostotic and six (28.6%) had monoostotic Paget's disease. More commonly involved bones were skull and spine (61.9%) followed by pelvis (38.1%), femur (33.3%), tibia (9%) and ulna (9%). Mean (+/-SD) serum alkaline phosphatase at diagnosis was 1514 +/- 1168 IU/L and nine months after treatment with bisphosphonates decreased to 454 +/- 406 IU/ L(P<0.03).
This illustrates that Paget's disease does exist in India and a high index of suspicion is required to clinch the diagnosis.
