NCT ID: NCT01108068 Completed - Clinical trials for Osteoporosis Pseudoglioma

Trial of Lithium Carbonate for Treatment of Osteoporosis-pseudoglioma Syndrome

Start date: July 2010
Phase: N/A
Study type: Interventional

This was a pilot study of 10 patients with Osteoporosis-pseudoglioma syndrome (OPPG) from the Old Order Mennonite community and 16 controls, who did not have OPPG. Five of the 10 OPPG patient elected to participate in the Lithium trial and 5 participated only in baseline data (labs, pQCT). The 5 with OPPG who were given lithium for 6 months had both dual energy xray absorptiometry (DXA), peripheral quantitative computerized tomography (pQCT) and lab assessment at baseline and 6 months. Studies in the mouse model of OPPG showed that lithium normalized their bone strength. Controls (n=16) were recruited from the Old Order Mennonite community, to minimize the effects of environmental and lifestyle factors. The controls were not be given lithium. The age range of participants was 4-64 years.

NCT ID: NCT00805493 Terminated - Bipolar Disorder Clinical Trials

Double-Blind Placebo-Controlled Trial of Riluzole in Pediatric Bipolar Disorder

Start date: November 2008
Phase: Phase 2
Study type: Interventional

Pediatric Bipolar Disorder (BD) is uncommon in children. Its symptoms include periods of manic behavior (being overly happy or giddy, feeling grandiose, feeling a decreased need for sleep, having too much energy, moving more than usual, talking fast, having speeded-up thoughts and other symptoms). Sometimes there also is depression (extreme feelings of sadness or irritability, not taking pleasure in things, even ones that used to be enjoyable, feeling worthless or guilty, sleeping too much or having trouble getting to or staying asleep, feeling slowed down or restless, having wishes to be dead or suicidal ideas, and other symptoms). Pediatric BD is often difficult to treat; children may respond only partially to the medications now available or have too many side effects to tolerate them. Riluzole is a medication that is thought to work on a brain chemical called glutamate that may be involved in symptoms of depression and BD. Previous research studies have shown that riluzole may help adults with BD who have depression and adults who have depression, anxiety disorders, or obsessive-compulsive disorders. Riluzole may also be helpful for children with obsessive-compulsive disorder. However, it has never been given to children with BD. This study will evaluate the effectiveness of riluzole in 80 patients between 9 and 17 years of age who have BD and symptoms of anxiety. Participants must have tried at least two other medications that have not been effective. The study will consist of four phases carried out over 4 to 5 months. Most children will be inpatients at the Pediatric Behavioral Health Unit for at least part of the study. In Phase 1, each patient will undergo blood and urine tests, and will gradually taper off his or her medication. The duration of this phase depends on the medication that the patient was receiving before starting the study. In Phase 2, the patient will remain off all medication for 1 week. Throughout this time, patients will be monitored carefully and medication will be restarted if needed. In Phase 3, which lasts 8 weeks, patients will be assigned randomly to receive only riluzole or only a placebo. Those who receive riluzole will have the dose adjusted as needed. Patients and families will be informed of which drug they were on at the end of this phase. Patients who improved on riluzole may continue to receive it from NIH for 1 month and will then be prepared for discharge from the study. Patients who received placebo and improved, and those who received riluzole but did not improve, will be treated with standard medications as appropriate and prepared for discharge from the study. Phase 4 is for patients who received placebo and did not improve. They will be given the chance to try riluzole for 8 weeks and, if it is effective, continue it for an additional 4 weeks while they prepare to be discharged from the study. Patients will not be able to receive riluzole at the National Institutes of Health after the completion of the study. However, the child's doctor may be able to prescribe riluzole as an off-label use. Most patients will be admitted to the Pediatric Behavioral Health Unit at the National Institutes of Health Clinical Center during the medication withdrawal part of the study (Phases 1 and 2). From Phase 3 on, a patient may participate as an inpatient, outpatient, or in day treatment, depending on what is in his or her best interests. All participants in this study will be invited to also enroll in the National Institute of Mental Health protocol 00-M-0198, The Phenomenology and Neurophysiology of Affective Dysregulation In Children And Adolescents With Bipolar Disorder. Some research tests for that protocol will be done during the medication-free period of this protocol.

NCT ID: NCT00774358 Completed - Clinical trials for Wiskott-Aldrich Syndrome (WAS)

Interleukin-2 Treatment for Wiskott-Aldrich Syndrome

WAS
Start date: October 2008
Phase: Phase 1
Study type: Interventional

Funding Source--FDA OOPD. Orphan Product Grant Number--1R01FD004091-01A1 Context: Wiskott-Aldrich syndrome (WAS) is a fatal, devastating disease with ill-defined treatment modalities, which affects young boys. Classic WAS is characterized by a clinical triad of thrombocytopenia, eczema and severe, recurrent infections. Despite diagnostic and therapeutic advances most WAS patients die at less than 12 years of age due to infections, hemorrhage, malignancy or complications from treatments. WAS patients suffer from herpesvirus infections as a result of poor Natural Killer (NK) cell function (cytotoxicity). In the laboratory, the investigators have seen correction of WAS Natural Killer Cell (NK) function after treatment with Interleukin-2 (IL-2). Objectives: Initiate a prospective clinical trial by treating WAS subjects with IL-2 and using safety as the primary endpoint. Restoration of NK cell cytotoxicity and effects on cytoskeletal dynamics are secondary endpoints. The investigators will also observe patient clinical status (eczema, infections, use of treatment dose antibiotics, food allergies, etc). Study Design/Setting/Participants: This is a prospective clinical trial treating 9 WAS subjects in the Clinical Translational Research Center (CTRC) with IL-2. Intervention: The investigators propose to subcutaneously administer 0.5 Million Units (MU)/m2 of IL-2 daily to WAS subjects for 5 days. Research treatment will be repeated 2 and 4 months later. Inter-patient dose escalation will be employed to 1 MU/m2 and/or 2 MU/m2 based on safety as the primary endpoint. Study Measures: The investigators will observe safety and tolerability measures and perform assays on subject blood samples prior to and after research treatment to observe improvement in NK cell function.

NCT ID: NCT00485186 Withdrawn - Clinical trials for Adrenal Insufficiency

Gene Polymorphisms Influencing Steroid Synthesis and Action

Start date: June 2007
Phase: N/A
Study type: Observational

The extend of steroid biosynthesis and action is mainly dependent on underlying genetic polymorphisms and gene mutations. These sequence variations in multiple genes involved in steroid biosynthesis and action cause different diseases (for example congenital adrenal hyperplasia or disorders of sex development). In addition, sequence variations in several other genes may influence the severity of a genetically caused disease of steroid biosynthesis or action. By this, the differences in an observed phenotype may be explained. Within the study all genes necessary for adrenal and gonadal steroid biosynthesis and several genes which are known to influence the action of steroid hormones will be analysed in patients with congenital disorders of adrenal and gonadal steroid biosynthesis, disorders of steroid action and disorders of sex development. The primary aim is to set up a correlation of the disease phenotype with the different genotypes detected.

NCT ID: NCT00474357 Recruiting - Clinical trials for Bipolar Affective Disorder

Myths About Bipolar Affective Disorder: The Role of Structured Group Psychoeducation Therapy

BAD
Start date: May 2007
Phase: N/A
Study type: Interventional

This study will examine: 1) The impact of psycho education group therapy sessions relating to beliefs/myths associated with bipolar affective disorder (BAD) on the emotional wellbeing, clinical course and cognition of individuals diagnosed with BAD 2) Will examine the existence of those same beliefs among the various caregivers - psychiatrists, general practitioners, social workers, and psychiatric nurses. The investigators hypothesize that psychoeducation group therapy will be effective in refuting the myths and will lead to better treatment adherence, longer remissions, fewer hospitalizations, improved self esteem, increased optimism, and better control over the disease process. The investigators also believe that they will identify some beliefs/myths or preconceived notions that are common to both caregivers and individuals with BAD.
