Brief Summary:

By supplying an adequate amount of calcium and vitamin D with the addition of weekly bisphosphonate, the investigators will be able to increase bone mass and decrease the incidence of fragility fractures in these children with muscular dystrophy.

The investigators think this treatment will also decrease the intensity of pain frequently present in these patients and slow the progression of scoliosis.

Condition or disease Intervention/treatment Phase
Osteoporosis Muscular Dystrophy Cystic Fibrosis Drug: Bisphosphonate treatment Phase 4

Detailed Description:

Children with muscular dystrophy, as well as children with other chronic diseases (e.g. cystic fibrosis, chronic inflammatory arthritis) are at risk to develop fragility fractures both due to the disease itself and to drugs (mostly corticosteroids) used to treat the diseases.

In addition, children with muscular dystrophy frequently complain of diffuse pain making daily care more difficult and almost always develop structural scoliosis.

The objective of the present protocol is to offer these children a preventive treatment aimed at maintaining or increasing their bone mass. We also propose that maintaining bone mass will decrease fracture rates, as well as pain and the rate of progression of scoliosis.

Rigorous care to ensure adequate intake of calcium and vitamin D, as well as addition of a weekly bisphosphonate, are the central aspect of the project. In addition, we will monitor to avoid possible side-effects such as hypercalciuria and kidney stones.

Arm Intervention/treatment
Experimental: Bisphosphonate treatment

Drug: Bisphosphonate treatment
Treatment with Calcium, vitamin D and a weekly bisphosphonate. Comparison of bone mass, fracture rate, pain intensity and scoliosis progression before and after treatment
Other Names:
  • Risedronate
  • Alendronate

Primary Outcome Measures :
  1. Increase in bone density according to osteodensitometry [ Time Frame: Over 2 years of treatment ]
    comparing successive bone densitometry

Secondary Outcome Measures :
  1. Decrease in bone pain [ Time Frame: Over the first 2 years of treatment ]
    comparing reports of bone pain

  2. Retardation of scoliosis development [ Time Frame: Over the first 2 years of treatment ]
    computing how many patients had to have scoliosis surgery

Other Outcome Measures:
  1. Side effects of treatment [ Time Frame: Over 2 years ]
    Look for increases in kidney stones or hypercalciuria
