Abstract

CONTEXT: Paget's disease of bone is a common bone disease with a striking variation in its incidence and characteristics in different parts of the world. It is uncommonly reported in African patients.

AIMS: Given the lack of studies describing the characteristics of patients with Paget's disease of bone in North Africa, we aimed to describe demographic, clinical, biochemical, and imaging characteristics, as well as treatment outcomes of Tunisian patients with Paget's disease of bone.

SUBJECTS AND METHODS: This bicentric and retrospective study included patients with Paget's disease of bone. Clinical, laboratory, radiological profile, and response to treatment were analyzed.

RESULTS: Sixty-nine patients were identified. The mean age was 64.9 ± 11.6 years and 52.2% were women. One patient reported a positive family history. Seven patients were asymptomatic. Bone pain was the most common presenting symptom. Eight patients had a history of malignancy. In three patients, Paget's disease of bone was diagnosed as part of a metastatic workup. Monostotic disease was found in half of the cases. The most commonly involved sites were pelvis (43.5%), femur (21.7%), and spine (21.7%). The mean serum alkaline phosphatase level at presentation was 591 U/L (68-8380). Two patients received salmon calcitonin (2.8%) and 47 patients (68.1%) received bisphosphonates. After a mean follow-up of 55 months (2-240 months), bone pain improved in 43.1% of patients and the serum alkaline phosphate levels had normalized in 22 of them (43.1%). During follow-up, there was no malignant transformation.

CONCLUSIONS: In this series of Tunisian patients, Paget's disease of bone had a female predominance and was usually monostotic. The clinical and radiological presentations were similar to the European series.
