Trial summary

This study will examine whether PET imaging can reveal what is happening in lymph nodes of patients with systemic lupus erythematosus, or lupus, during periods of active disease. Patients may have periods of active disease when they may feel sick with fever, fatigue, and aching or swollen joints. Read more about this study

About this study

Official title: A Pilot Study of F-18FDG Positron Emission Tomography (PET) to Assess the Distribution of Activated Lymphocytes in Systemic Lupus Erythematosus (SLE)

This study will examine whether PET imaging can reveal what is happening in lymph nodes of patients with systemic lupus erythematosus, or lupus, during periods of active disease. Patients may have periods of active disease when they may feel sick with fever, fatigue, and aching or swollen joints. Their blood tests are abnormal and their kidney, lungs or heart may be affected. At other times, the disease is inactive, and patients feel well, their blood is normal, and there is no evidence of organ disease.

In lupus, like other autoimmune diseases, the body's immune system attacks it own healthy tissues. Activated lymphocytes (a type of immune cell) lead to the production of antibodies and chemical signals that contribute to the disease process. In animals with lupus, these cells are activated in the lymphoid organs, such as the lymph nodes or spleen. It is not known exactly where these cells are activated in humans. Because some lymph nodes are located deep inside the chest and abdomen; surgery is currently the only way to examining them. PET imaging may provide an alternative, non-invasive, means of obtaining information on lymph node activity in humans. This test uses a radioactive sugar molecule called F18-FDG to find areas of increased cellular activity in the body. (Cells use sugar for fuel, so active cells, such as active lymphocytes, uses more FDG than other body tissues.) This study will determine whether PET can detect these areas of increased activity in lupus during active disease.

Patients with active or inactive lupus may be eligible for this study. Candidates are screened with a history, physical examination, and routine blood and urine tests. Women who are pregnant or breastfeeding may not participate.

Participants will undergo PET scanning. On the day of the scan they have a brief medical history and physical examination and a blood sample is drawn to check blood count and look for markers of lymphocyte activation. Then, a small plastic tube (catheter) is placed into a vein in the patient's arm, the FDG is injected through the catheter, and the patient rests for an hour. For the scan, the patient lies flat in a cradle that is moved into the central hole of the doughnut-shaped PET camera, and pictures are taken over the next 2 hours, with the patient lies quietly, without moving the head or arms. After the scan is finished, the patient empties the bladder approximately every hour for 6 hours to excrete the radioactive sugar.

Read the detailed description

This pilot study aims to evaluate the value of Positron Emission Tomography (PET) in assessing the distribution of activated lymphocytes in SLE patients. Systemic lupus erythematosus (SLE), often defined as the prototypical autoimmune disease, is a chronic occasionally life threatening, multisystem disorder. Determining disease activity in SLE is essential for the selection of appropriate and effective therapeutic regimes. Lymphocyte activation is the hallmark of SLE and correlates well with disease activity. 2-deoxy-2 [F-18] fluoro-2-D-Glucose positron emission scanning (FDG-PET) is a physiologically based method of imaging that provides non-invasive information on uptake and metabolism of glucose in various tissues. Actively metabolizing cells will preferentially take up the radioactively labeled glucose analog and therefore demonstrate increased signal. Actively proliferating lymphocytes take up FDG at a higher rate than resting lymphocytes and are expected to accumulate in selected lymph nodes or spleen that are the anatomic sites of lymphocyte activation. Lymphocyte activation will be confirmed by FACS analysis of circulating lymphocytes.

This study is designed as a single center pilot study with two groups of patients divided into active vs. non-active SLE and both groups will undergo FDG-PET scanning. The primary objective will be to evaluate the feasibility of FDG-PET in assessing distribution of activated lymphocytes in active and inactive SLE patients. The goal is to detect activated lymphocytes at their homing sites and correlate the pattern of distribution with clinical disease activity.

Questions about this trial

What is this clinical trial studying?

An observational study of Lupus Erythematosus and Systemic, run by National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00029926, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
