In this 2-year study, children aged 6-18 who have JRA will take either a calcium supplement or a matching placebo (inactive or \"dummy\" pill) containing no calcium. During the study, researchers and patients will not know if a patient is taking calcium or placebo. We believe that patients who take calcium supplements will have at least a 10 percent greater increase in total body bone mineral density compared to patients who take the placebo.\n\nWe will evaluate patients at Children's Hospital Medical Center every 6 months for 2 years. During this 2-year period, participants in the study will take one multivitamin containing 400 IU (international units) of vitamin D and either 1,000 mg of calcium carbonate (Tums tablets) by mouth or a matching placebo once a day. We will check patients 6 and 18 months after the 2-year treatment period to find out if people in the Tums-treated group maintain any increases in bone formation that occurred during the 2-year treatment period.", "DetailedDescription"=>"This is a randomized, double-blind, placebo-controlled trial of 24 months in which juvenile rheumatoid arthritis (JRA) patients will take either an oral calcium supplement of 1,000 mg elemental calcium per day or a matching placebo containing no calcium (Ca), plus one multivitamin per day. We hypothesize that patients receiving calcium supplementation will demonstrate at least a 10 percent greater increase in total body bone mineral density compared to those treated with placebo.\n\nWe will evaluate patients at Children's Hospital Medical Center (CHMC) every 6 months for 2 years. We will also evaluate patients 6 and 18 months after the end of the intervention period to determine the persistence of any demonstrated increased bone mineralization in the Tums-treated group. The study requires analysis of human blood and urine samples and low-dose radiation exposure.\n\nWe have randomized 193 JRA patients equally into two treatment groups (active and placebo). The active treatment group is taking, in a single daily dose, two 500 mg tablets of elemental Ca as CaC03 (calcium carbonate) and one multivitamin tablet containing 400 IU vitamin D. The placebo treatment group is taking, in a single daily dose, two placebo tablets (matched on size, appearance, and taste) containing 0 mg elemental Ca and one multivitamin tablet containing 400 IU vitamin D. We do all patient evaluations in the Clinical Research Center at Children's Hospital Medical Center.\n\nEvery 6 months during the 2-year intervention trial, we will perform interval history, general and joint physical exam, anthropometric measurements (height, weight, BMI), pill counts, MMEM monitor check, DXA scan of total body and lumbar spine for bone mineral density, and dispensing of study drugs. At yearly intervals during the intervention trial, we will do the Youth/Adolescent Questionnaire (YAQ) on diet (which is validated for 1-year recall), 3-day diet diary for current intake, blood tests for mineral and calcitropic hormone concentrations, 24-hour urine for measurements of bone turnover markers and mineral excretion, physical function assessment (JAFAR), and physical activity questionnaire. We will obtain blood for determining vitamin D receptor (VDR) genotype at baseline only. We will perform fasting random urine tests to determine Ca/creatinine ratio to assess for treatment-induced hypercalciuria at months 0, 3, 6, 12, 18, and 24.\n\nMonthly during the intervention trial, the study coordinator will contact all participants by phone in a blinded fashion to increase compliance and encourage continued participation in the trial. We will evaluate participants 6 and 18 moths after the end of the intervention trial. At each of these visits, we will obtain the following: general and medication history, general and joint physical exam, Tanner Stage, anthropometric measurements, blood for minerals and calcitropic hormones, 24-hour urine collection for measurements of bone turnover markers and mineral excretion, JAFAR, physical activity questionnaire, and total body and lumbar spine DXA scans. The YAQ and 3-day diet diary will be completed at the 42-month visit. Prior to every DXA scan, we will do a urine pregnancy test in all menstruating females to ensure that they are not pregnant. Any patient who withdraws from the blinded portion of the study early will complete an evaluation as outlined for the 24 months visit. Patients who withdraw early during the open phase of the study will complete the 42 months evaluation.\n\nWe will exclude from the study people who have recently taken systemic corticosteroids, people taking oral contraceptives, smokers, and pregnant women because these factors have been shown to significantly lower bone mineralization. We will withdraw subjects from the study if they demonstrate an elevated fasting random urinary calcium/creatinine ratio (>0.2), a chronic disease in addition to JRA that affects growth or bone mineralization, or they become pregnant. We will include these patients and all those withdrawing from the study voluntarily in an \"intention-to-treat\" analysis."}, "EligibilityModule"=>{"Gender"=>"All", "MaximumAge"=>"18 years", "MinimumAge"=>"6 years", "StdAgeList"=>{"StdAge"=>["Child", "Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"Inclusion Criteria:\n\nJRA Diagnosis by American College of Rheumatology diagnostic criteria\nAge 6-18 years\n\nExclusion Criteria:\n\nTaking calcium supplements or calcium- containing antacids\nTaken systemic corticosteroids in the prior 3 months\nUse of oral contraceptives\nSmoker\nHave been or currently pregnant\nHave another chronic illness that affects growth or bone mineralization (for example, Down's Syndrome, inflammatory bowel disease, steroid-dependent asthma)\nFasting random urinary calcium/creatinine ratio > 0.2"}, "IdentificationModule"=>{"NCTId"=>"NCT00000429", "BriefTitle"=>"Calcium Supplements for Bone Health in Juvenile Rheumatoid Arthritis", "Organization"=>{"OrgClass"=>"OTHER", "OrgFullName"=>"Children's Hospital Medical Center, Cincinnati"}, "OfficialTitle"=>"Calcium Supplementation for Bone Mineralization in Juvenile Rheumatoid Arthritis (JRA)", "OrgStudyIdInfo"=>{"OrgStudyId"=>"P60AR044059", "OrgStudyIdLink"=>"https://reporter.nih.gov/quickSearch/P60AR044059", "OrgStudyIdType"=>"U.S. NIH Grant/Contract"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"P60AR044059", "SecondaryIdLink"=>"https://reporter.nih.gov/quickSearch/P60AR044059", "SecondaryIdType"=>"U.S. NIH Grant/Contract"}, {"SecondaryId"=>"NIAMS-020"}]}}, "ArmsInterventionsModule"=>{"InterventionList"=>{"Intervention"=>[{"InterventionName"=>"Calcium carbonate", "InterventionType"=>"Drug"}]}}, "ContactsLocationsModule"=>{"LocationList"=>{"Location"=>[{"LocationZip"=>"45229", "LocationCity"=>"Cincinnati", "LocationState"=>"Ohio", "LocationCountry"=>"United States", "LocationFacility"=>"Children's Hospital Medical Center"}]}, "OverallOfficialList"=>{"OverallOfficial"=>[{"OverallOfficialName"=>"Daniel J.
