Research at the Clinical Center

Published Clinical Research Conducted at the Clinical Center

The NIH Clinical Center is the world’s largest hospital entirely devoted to clinical research. It is a national resource that makes it possible to rapidly translate scientific observations and laboratory discoveries into new approaches for diagnosing, treating, and preventing disease.

Over 1,600 clinical research studies are conducted at the NIH Clinical Center, including those focused on cancer, infectious diseases, blood disorders, heart disease, lung disease, alcoholism and drug abuse.

Here is a sample of abstracts from the clinical research conducted at the NIH Clinical Center and published in a peer reviewed medical journal this year. Links to the full text and video formats are provided if available.

Psychedelic-assisted psychotherapy to treat psychiatric and existential distress in life-threatening medical illnesses and palliative care

Published in: Neuropharmacology (September 2022)

Studies suggest preliminary evidence that psychedelic-assisted psychotherapy may provide robust and sustained quality-of-life improvements for patients in life-threatening or palliative situations. These patients experienced less anxiety, depression, suicidal ideation and existential distress. More rigorous research is recommended to further assess effectiveness of these psychedelic therapies.

Plasma Cell-Free DNA Predicts Survival and Maps Specific Sources of Injury in Pulmonary Arterial Hypertension

Published in:  Circulation (August 2022)

Risk prediction in pulmonary arterial hypertension (PAH) remains a major challenge. Cell-free DNA (cfDNA) is a noninvasive marker of cellular injury and its significance in pulmonary arterial hypertension (PAH) is unknown. In two PAH cohorts, plasma cfDNA was measured and found elevated in patients with PAH compared with healthy controls and increases with disease severity.

An exploratory study of pro-inflammatory cytokines in individuals with alcohol use disorder: MCP-1 and IL-8 associated with alcohol consumption, sleep quality, anxiety, depression, and liver biomarkers

Published in: Frontiers in Psychiatry (August 2022)

Chronic sleep disturbances from heavy alcohol use may contribute to a sustained inflammatory state. Researchers examined pro-inflammatory cytokines in individuals with alcohol use disorder (AUD) and found associations with inflammation and alcohol consumption, sleep quality, anxiety and depression. Further research on inflammation in individuals with AUD is needed.

Improvement of liver metabolic activity in people with advanced HIV after initiation of antiretroviral therapy

Published in: AIDS (July 2022)

Using advanced imaging (PET/CT), we found low glucose metabolism in the liver of untreated people living with HIV had improved, but did not resolve completely after long-term antiretroviral therapy. Residual liver metabolic changes in people with HIV after treatment should be further evaluated.

Examining the Relationships Between Sleep Physiology and the Gut Microbiome in Preclinical and Translational Research: Protocol for a Scoping Review

Published in: JMIR Publications (June 2022)

Researchers developed a protocol outlining methods to review research studying sleep and the gut microbiome. This research has been undertaken to determine the methodologies used to quantify sleep and the microbiome and synthesize microbiome responses associated with healthy/unhealthy sleep.

Low-dose methylprednisolone treatment in critically ill patients with severe community-acquired pneumonia

Published in: Intensive Care Medicine (May 2022)

Severe community acquired pneumonia (CAP) requiring Intensive Care Unit admission causes significant morbidity and mortality. Treatments directed at reducing inflammation in severe CAP have potential benefit. In a randomized multi-center trial of 586 patients with severe CAP, corticosteroid treatment did not significantly reduce 60-day mortality.

Early Intervention for Very Young Children with or at High Likelihood for Autism Spectrum Disorder: An Overview of Reviews

Published in: Developmental Medicine & Child Neurology (May 2022)

Autism spectrum disorder (ASD) is a neurodevelopmental condition with early childhood symptoms. As a result, there is growing movement toward identifying ASD during early, more rapid periods of brain development to initiate interventions sooner. However, while two different approaches show positive effects on outcomes, the added benefits of earlier interventions still lack strong evidence.

Fully Automated Abdominal CT Biomarkers for Type 2 Diabetes Using Deep Learning

Published in: Radiology (April 2022)

Researchers investigate computed tomography (CT) biomarkers that may be associated with the presence of type 2 diabetes using fully automated deep learning. The researchers found changes in the pancreases of patients as early as 7 years before the patients were diagnosed with diabetes.

Cone-Beam Computed Tomography-Based Spatial Prediction of Drug Dose After Transarterial Chemoembolization Using Radiopaque Drug-Eluting Beads in Woodchuck Hepatocellular Carcinoma

Published in: Investigative Radiology (March 2022)

CT imaging was used to predict the distribution of chemotherapy following intra-arterial delivery of drug-releasing microspheres to a woodchuck liver tumor. This “drug mapping” concept could improve  drug targeting and coverage of tumors, reducing side effects and improving treatment outcomes for patients with liver cancer.

Assessment of Aortoiliac Atherosclerotic Plaque on CT in Prostate Cancer Patients Undergoing Treatment

Published in: PubMed (March 2022)

Researchers compared atherosclerotic plaque in major arteries of the abdomen and pelvis of men with and without prostate cancer. The atherosclerotic plaque in prostate cancer patients did not differ from the normal control group, but were closely associated with age and heart disease.

Increased serum pro-B-type natriuretic peptide in hematopoietic progenitor cell donors stimulated with G-CSF

Published in: Journal of Clinical Apheresis (March 2022)

In a case series of 18 healthy stem cell donors who received a common stimulation regimen, a protein that is commonly associated with heart failure increased transiently in their blood. The long-term impact on donor’s health is pending evaluation.

Mineralocorticoid receptor antagonist treatment of established pulmonary arterial hypertension improves interventricular dependence in the SU5416-hypoxia rat model

Published in: American Journal of Physiology | Lung Cellular and Molecular Physiology (January 2022)

High-resolution cardiac MRI demonstrated that mineralocorticoid receptor blockade improved ventricular interdependence in a rat model of pulmonary arterial hypertension (PAH). This supports the use of advanced cardiac imaging in an ongoing clinical trial of spironolactone in PAH patients at the NIH Clinical Center.
