This trial will test the hypothesis that among 20 children and adolescents from Children's Hospital, Boston with Crohn's disease, ulcerative colitis, systemic-onset juvenile rheumatoid arthritis, juvenile dermatomyositis, systemic lupus erythematosus, mixed connective tissue disease and vasculitis, treatment of glucocorticoid-associated osteopenia and osteoporosis with 18 months of alendronate (FOSAMAX®, Merck & Co., Inc.) will result in greater improvement in the mean change of individual AP spine bone mineral density (BMD) (gm/cm2) determined by dual energy X-ray absorptiometry (DXA) than treatment with 18 months of standard of care therapy.

Ages Eligible for Study:
8 Years to 22 Years (Child, Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Subjects must be diagnosed with either ulcerative colitis, Crohn's disease, systemic-onset juvenile rheumatoid arthritis, juvenile dermatomyositis, systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD) or vasculitis according to standard criteria where available, and according to treating physicians when not available.
Subjects must have diminished AP lumbar spine (L1-L4) BMD by DXA (Hologic 4500) with a Z score ≤ -1.5 SD assessed within 8 weeks of the Baseline Visit.
Subjects must have received daily, alternate day or weekly systemic glucocorticoid therapy for a minimum of six months total in their life-time.
Subjects must be between the ages of 8 and 21 years, 11 months, at randomization. Although subjects younger than 8 years of age may be affected by osteoporosis, limited normative data prevents assignment of a BMD Z score for this group.
Regarding subjects with child-bearing potential Females who have had at least one menstrual cycle must either be abstinent or must be using an effective method of birth control.
Current or recent (within 6 months) treatment with therapeutic doses of a bisphosphonate, calcitonin, human growth hormone, and heparin, all agents known to alter bone density
A history of recent (within one year of screening) major upper gastrointestinal (GI) disease (above the jejunum), including, but not limited to, peptic ulcer, esophageal disease or active GI bleeding, or ever had surgery of the upper GI tract other than pyloroplasty. A history of abnormalities of the esophagus which delay esophageal emptying, such as stricture or achalasia
Hyperthyroidism (suppressed thyroid stimulating hormone (TSH) and elevated free thyroxine (T4)), hyperparathyroidism (elevated parathyroid hormone (PTH)), malignancy, rickets, or osteomalacia (by history), all assessed within 8 weeks of the Baseline Visit.
25 (OH) vitamin D below 20 mg/L
Planned or current pregnancy and/or breastfeeding
Renal dysfunction defined as dependence on dialysis or a creatinine clearance < 35 ml/min, assessed within 4 weeks of the Baseline Visit. Creatinine clearance = [(height in cm x 0.55)/plasma creatinine] for all females and for males < 13 years old; [(height in cm x 0.70)/plasma creatinine] for males ³ 13 years old.
Hepatic insufficiency defined as SGPT or SGOT greater than twice normal for age, assessed within 4 weeks of the Baseline Visit.
Uncorrected hypocalcemia (ionized calcium>10% below age-adjusted range), assessed within 4 weeks of the Baseline Visit
Known or suspected hypersensitivity to bisphosphonates
Inability to follow instructions for dosing, including being unable to swallow the study medication with plain water first thing in the morning, stand or sit upright without any other food or beverage for at least 30 minutes following dosing and until their next meal
Weight greater than 136 kg (300 lb), as the DXA is not reliable for subjects of this size
Weight less than 17 kg (37 lb), assessed within 8 weeks of the Baseline Visit
Permanent foreign body (prosthetic, surgical clips, permanent earring/umbilical ring) in region of results of the study
Enrollment Procedures interest, or soft tissue calcinosis overlying the region of interest
Inability to undergo dual energy X-ray absorptiometry or CT scan
Developmental or cognitive delay which may interfere with cooperation and/or compliance with the procedures
Subject expects to move out of the area during the study period, rendering follow-up per protocol impractical
