  1. Tenosynovitis in children with inflammatory arthritis

     

    Background:

    In children with juvenile idiopathic arthritis (JIA) clinical examination seems to be not very reliable in terms of detection of inflammatory changes in joints and joint structures. For the determination of the extent of inflammation imaging plays an increasing role in pediatric rheumatology. Synovitis has been thoroughly studied both in musculo-skelettal ultrasound (MSUS) and magnetic resonance imaging (MRI). In contrast to adult rheumatomlogy, in pediatric rheumatology only little knowledge exists on the presence of tenosynovitis and only few articles have been published on that topic. All publications point to the presence of tenosynovitis frequently clinically not detectable and frequently present in patients with clinically inactive disease.

    Tenosynovitis represents disease activity and being clinically not detectable the influence on the outcome of the patient hasn’t neither been addressed nor measured so far, although tenosynovitis could be one major factor for the loss of hand function.

     

    Objective:

    To study tenosynovitis in children with inflammatory arthritis and to develop a scoring system for grading tenosynovitis as a measurement for disease activity.

     

    Methods:

    Following the OMERACT filter 2.0 the following steps will be taken:

    - Literature Review and definition of the items/sites of tenosynovitis

    - Consensus process on definition and grading of US tenosynovitis

    - Reliability of US-assessed (presence and grade) tenosynovitis in JIA

    - Construct validity of US in detecting and scoring tenosynovitis as compared with MRI

    - Construct validity of US in detecting and scoring tenosynovitis as compared with hand measurements (e.g. power, grip etc.)

Objectives:

Accurate musculoskeletal ultrasound (MSUS) assessment of disease activity and joint damage is essential in the clinical management of children with Juvenile idiopathic Arthritis (JIA). Several studies have described improved sensitivity for detection of joint inflammation with the use of ultrasound as compared with clinical assessment. But there is still a lack of validated normal B-Mode and Power Doppler sonographic findings in different age groups. The development of the skeletal system with different stages of maturity of the ossification nuclei, has to be taken into account performing MSUS in children.

At birth, cortical bone is present in most of the long bone diaphyses representing the primary ossification center. The secondary ossification centers in the epiphyses will only subsequently become apparent. In a recently published ultrasound study assessing the skeletal development of newborns, the dimension of the ossification centers correlated well with the age and maturity of the newborns. Children with juvenile idiopathic arthritis may have an accelerated bone development following  inflammation and hypervascularization of affected joints. It seems to be very  important and helpful for the rheumatologist to assess the skeletal maturity of examined joints in children. The OMERACT pediatric ultrasound subtask group has recently agreed a new four-degree score to assess the ossification stage of different joints. The first practical study assessing skeletal maturity by the new semiquantitative score in healthy children showed a very good applicability and was found to correlate well with the age of probands. A very good interobserver and intraobserver agreement shown by high kappa values and intraclass coefficients was calculated. The semiquantitative score seemed to be a very practicable tool and should be tested now on different joints of a higher count of probands and patients e.g. with juvenile idiopathic arthritis.

Scientific/Medical Rationale – Aim of the project

  1. One objective of the project is to evaluate the development of ossification in several joints in healthy children and to produce an atlas of childhood ossification with sonographic anatomic landmarks for age- and sex-dependent ossification in children.

  2. A second objective includes the evaluation of accelerated ossification in joints of patients with JIA.

  3. A third objective is to validate the recently agreed ossification score in different joints in healthy children and patients with JIA.

Procedures/ Agenda

1. Literature Review “ossification”

2. Healthy joints (images, multi-observer exercise)

3. JIA patients (images, multi-observer exercise)
