arcOGEN

Arthritis Research UK Osteoarthritis Genetics (arcOGEN) is a collection of 7410 unrelated, UK-based individuals of European ancestry with knee and/or hip osteoarthritis from the arcOGEN Consortium. Samples were collected in 2 stages from 10 United Kingdom locations (London, Nottingham, Oxford, Sheffield, Southampton, Edinburgh, Newcastle-Upon-Tyne, Sheffield, Wansbeck, and Worcester). The majority of cases had primary OA requiring joint replacement of the hip or knee while a smaller number were ascertained by radiographic evidence of disease (Kellgren-Lawrence (KL) grade ≥2). The exclusion criteria included the need for joint replacement due to fracture, secondary OA of any cause, and developmental, vascular, or infective causes of joint disease.

Japanese OA cohort

The Japanese cohort of knee OA GWAS (disease cohort) consists of 900 cases and 3,400 controls. The cases were all symptomatic OA. They were diagnosed and recruited by expert orthopedic surgeons based on clinical and radiographic examination. All had clinical records for OA and radiographs (standing knee A-P). The controls were obtained from Biobank Japan. The genotyping was done by using Illumina HumanHap550v3 Genotyping BeadChip. After excluding cases with call rate of <0.98, we applied SNP QC (call rate of ≥0.99 in both cases and controls and P value of Hardy-Weinberg equilibrium test of ≥1.0×10−6 in controls). Finally, 459,393 SNPs on autosomal chromosomes passed the QC filters (Nakajima M, et al. PLoS One 18;5(3):e9723, 2010.

 

Johnston County Osteoarthritis Project (JoCoOA)

For 30 years, the Johnston County Osteoarthritis Project (JoCoOA) in Smithfield, NC has established itself as one of the premier longitudinal research studies world-wide regarding the epidemiology of osteoarthritis.

Funded by the Centers for Disease Control and Prevention (CDC), the National Institutes of Health, and multiple other sources, it is internationally recognized as the flagship study of the UNC Thurston Arthritis Research Center. It was one of the first studies in the US to examine the incidence, prevalence and progression of osteoarthritis in African American and white men and women in a rural county.

The hallmark of this study is its population-based cohort. The strength of a population-based study is that results can be applied to the general population regarding lifetime risk or prevalence of a disease.

Stability is of paramount importance in the life of a research study. The Johnston County Osteoarthritis Project has been continuously managed by the same research team, has benefited from the direction and oversight of the same Project Officer at the CDC, has had its radiographs read by a single musculoskeletal radiologist, and the majority of its interviewers and research clinic examiners have been with the study for a decade or more.

Recently, the Johnston County Osteoarthritis Project received renewed funding from the CDC that extends to 2021. Enrollment was opened in 2019 to new participants to address naturally-occurring attrition over the past two and a half decades. The new enrollment includes a younger cohort of participants, starting at age 35, and White, African American, and for the first time, Hispanic men and women.

The Norwegian Arthroplasty Register

In 1985, the Norwegian Orthopaedic Association decided to establish a national hip register, and the Norwegian Arthroplasty Register was started in 1987. In January 1994, it was extended to include all artificial joints. The main purpose of the register is to detect inferior results of implants as early as possible. All hospitals participate, and the orthopedic surgeons are supposed to report all primary operations and all revisions. The register contains information on 221,913 hip arthroplasties, 89,410 knee arthroplasties, 8,466 shoulder arthroplasties and 9,949 arthroplasties in other joints. In 2017 10,583 hip arthroplasties and 7,188 knee arthroplasties were operated and we received reports from 57 Norwegian hospitals.

QIMR

Over 50’s (Aged) and Osteoarthritis (OA) Studies

The QIMR cohort consists of twins recruited to two studies conducted at QIMR Berghofer Medical Research Institute: the Over 50’s (Aged) and Osteoarthritis (OA) Studies.

The Aged Study was conducted in 1993 as a multi-wave mailout to 4562 twins (2281 pairs) aged over 50 years old who were registered with the Australian Twin Registry. In total, 3116 individuals (1279 complete pairs and 558 singles) completed and returned the 16-page questionnaire form. Self-report osteoarthritis data was collected in the ‘Bones and Joints’ section in collaboration with the Australian Arthritis Foundation, and in consultation with Nick Bellamy and David Duffy. Participants were questioned about ever having experienced pain, swelling or stiffness in any joints; prior diagnosis of osteoarthritis or degenerative arthritis, rheumatoid arthritis, and other forms of arthritis or rheumatism; as well as prior bone fracture or joint injury. Self-report of pain and/or swelling in the joints of the hands, hips and knees were used as indicators of potential osteoarthritis, excluding those joints indicated to have sustained prior injury. Genome-wide data are available for 933 participants for OA at any site and age of onset for OA. 

The OA Study was designed to investigate how similar identical and non-identical twins are to each other and reach an estimate of the effect of genetic and environmental influences on OA in the general population. The study conducted in 1994 where 441 twin pairs answered questions about prior diagnosis of OA; presence of pain or swelling in target joints for OA; and onset of joint pain/swelling not due to trauma after age 45. In addition, clinical examinations were performed by three Rheumatologists on 159 subjects, where approximately half were considered to be normal. Examinations of the twin's medical records and joint radiographs were conducted, where available. OA diagnosis involved comparing the self-report, clinical examination and radiological assessments. GWAS data is available for 1,073 participants (including 931 of the Aged Study participants) for OA at any site, hip OA, knee OA, hand OA and hip-knee OA.

 

Research Arthritis and Articular Cartilage study
