Study start date: April 1, 2000Actual date on which the first participant was enrolled.

Registry participants will have a blood sample drawn and will be interviewed about their medical histories. Participants will be asked to return for a follow-up visit after two years. Clinical, demographic, and laboratory data will be collected. Registry resources will be made available to researchers and medical practitioners to support a broad range of research on the causes, diagnosis, mechanisms, and treatment of APS. The University of North Carolina at Chapel Hill is the coordinating center and an enrollment site for the registry. There are seven other enrollment sites: Ball Memorial Hospital, Muncie, IN; Duke University, Durham, NC; Hospital for Special Surgery, New York, NY; Johns Hopkins University, Baltimore, MD; Morehouse School of Medicine, Atlanta, GA; University of Texas Health Science Center, San Antonio, TX; and University of Utah Health Science Center, Salt Lake City, UT.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
860 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Cohort
These studies follow a group of individuals with common characteristics (such as a condition or birth year) over a specific period to study health outcomes or exposures.

What happens to patients' samples
Samples from participants are kept, and they can be used to extract DNA in the future. These might include things like blood or frozen tissue. This allows researchers to study genetics and how DNA may relate to the disease.

Other Options for Sample Use
Samples Without DNA: Samples are kept but not usable for DNA analysis.
None Retained: No samples are kept after the study.

How participants are selected
Participants are selected without using randomization. They may be chosen based on convenience, access, or willingness to participate. This approach is common when random selection isn’t practical.
Another way to select participants is through a probability sample, where participants are chosen randomly, so everyone has an equal chance to be included.

How information is collected
Researchers start collecting data from the present day forward, following participants over time to observe outcomes. This approach helps identify how exposures or behaviors may lead to health events in the future.

Other Ways to Collect Data
Retrospective: These studies use existing medical records or past data.
Cross-sectional: These studies collect data at one single point in time.
Others: Some studies use a mix of approaches or less common designs depending on the research goal.
