Brief Summary
Joint pain has been reported as a major problem in people with haemophilia (PwH). Therefore, haemophilia in adults seems clinically more related to a musculoskeletal disorder than a bleeding disorder, with many patients reporting a pain intensity exceeding 6/10 on a visual analogue scale. However, although the complexity of joint pain has been studied in chronic joint pain conditions such as low back pain, osteoarthritis or rheumatoid arthritis, until present only very limited research has been done on joint pain within PwH. Therefore, exploring the underlying mechanisms and the functional implications of this intense joint pain is urgently needed. As such, the main aim of the current prospective observational study is to gain more insights in joint pain in PwH enabling us to move towards adequate pain management in PwH.

At one year follow-up (T2)
Pain severity
The BPI was used to evaluate the individual's pain experience within the last 24 hours by four items, resulting in a total pain severity score. Minimum score 0, maximum score 10. The higher te score, the higher the pain severity.
At baseline (T0)
Pain severity
The BPI was used to evaluate the individual's pain experience within the last 24 hours by four items, resulting in a total pain severity score. Minimum score 0, maximum score 10. The higher te score, the higher the pain severity.
At one year follow-up (T2)
Pain interference
The BPI was used to evaluate how much pain interferes with patient's daily activities. This was assessed by seven items, resulting in a total pain interference score. Minimum score 0, maximum score 10. The higher the score, the more pain interference.

At one year follow-up (T2)
Signs of neuropathic pain
The Douleur Neuropathique en 4 questions (DN4) was applied as a screening tool for the presence of a neuropathic pain component. Minimum score 0, maximum score 10, a score of ≥4/10 was used as a cut-off.
At baseline (T0)
Signs of central sensitization
The Central Sensitisation Inventory (CSI) part A was used to identify signs of central sensitization (CS) i.e. increased sensitivity of nociceptive neurons in the central nervous system.The presence of 25 pain-related psychological, cognitive and functional signs are scored from 0 (never) to 4 (always). A total score exceeding ≥40/100 indicated central sensitization.
At baseline (T0)
Pain Catastrophizing
The Pain Catastrophizing Scale (PCS) asked participants to reflect on previous painful experiences and to rate their degree of catastrophic thinking in the content domains of rumination, magnification and helplessness. A score of 0 (not at all) to 4 (all the time) was indicated for each of the 13 items, resulting in a total score range of 0-52. Higher scores were associated with higher levels of pain catastrophizing.
At baseline (T0)
Anxiety and Depression
The Hospital Anxiety and Depression Scale (HADS) was used to establish symptoms of anxiety and depression. This 14-item questionnaire consists of two subscales each including 7 items, the first to identify anxiety and the second depression. Individual items were scored from 0 to 3, resulting in a total range score of 0-21 for each subscale. A score of ≥8/21 was determined as a cut-off, indicating anxiety and depression.
At baseline (T0)
Fear Avoidance and Beliefs
The fear avoidance and beliefs questionnaire (FABQ) will be used to assess fear avoidance behaviors. The first five items question physical activity, the other 11 activities work. A minimum score is 0, maximum 24. Higher scores indicate fear avoidance behaviors.
At baseline (T0)
Life quality
The EQ-5D-5L was used to assess quality of life. From five items investigating the impact of their disease, a health utility score was calculated. Additionally, the questionnaire consists of a visual analogue scale (VAS) labelled from 0: "worst imaginable health state," to 100 "best imaginable health state" providing the EQ-VAS.

Haemophilia Activity Limitations
The Haemophilia Activity List (HAL) was used to assess activity limitations and participation restrictions people with haemophilia suffer with. A sum score and component scores can be calculated, resulting in scores ranging from 0-100. Lower scores represent higher levels of participation restrictions.
At baseline (T0)
Physical endurance ability
The 2 minutes walking test (2MWT) was used as a performance-based test to assess their functional activity. Subjects were asked to walk as far as possible for two minutes in a 30 meters flat corridor, resulting in the walking distance in meters.
At baseline (T0)
Physical functioning
The Timed Up \& Go (TUG) consists of asking the patient to sit on a standard armchair; stand up and walk 3 meters; turn around at the line and walk back to the chair and sit down at a normal pace.
At baseline (T0)
Joint structure US
Ultrasound (US) examinations will be performed with a linear probe (3-13 MHz) Esaote, type MyLab Gamma, Genova, Italy).The Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) scanning procedure and scoring method will be performed by one of our investigators. A score of 0/8 (normal bone 0/2, normal cartilage 0/4, absent hypertrophic synovium 0/2) is considered normal. A score above 1/8 is considered as abnormal.
At baseline (T0)
Joint structure MRI
Magnetic Reasoning Imaging (MRI) of the ankles will be performed with a 3T-magnet (GE Signa Premier, GE Healthcare, Milwaukee, USA).Joint images will be classified with the international Prophylaxis Study Group (IPSG) scale. Joints will be classified as abnormal if talocrural joints or subtalar joints were positive at IPSG-score. Joints will be considered healthy if the total score was of 1/17.
At baseline (T0)
Illness perceptions
The illness perceptions questionnaire (B-IPQ) includes nine items ranging from 0 (minimum) to 10 (maximum) and questions the perceptions related to the patients disease. No total score exists, as each item is scored individually. Higher scores indicate more negative or unhelpful illness perceptions. A change score between baseline (T0) and one year follow-up (T2) will be calculated.

Study Arms (1)
Haemophilia
Adult males with severe or moderate haemophilia A or B
Interventions
At baseline (T0) patients underwent the somatosensory pain assessment, joint structure and function assessment and filled in all questionnaires. During one month after baseline (T1) patients wore an activity tracker and filled in the Illness Perceptions Questionnaire and the International Physical Activity questionnaire. During one year after the baseline assessment (T2) patients filled in every month The Brief Pain Inventory, Illness Perceptions Questionnaire and the EQ-5D-5L quality of life questionnaire.
Eligibility Criteria
Adult males with moderate or severe Haemophilia A or B will be recruited from the Haemophilia Treatment Centers in Antwerp (Antwerp University Hosptial) and Brussels (Cliniques universitaires Saint-Luc). Age-matched healthy control subjects will be recruited from family and acquintances of the researchers and hospital/university personnel.
You may qualify if:
- adult (18-65y) patients with moderate (i.e. between 1 and 5 % normal Factor activity) or severe (less than 1% normal Factor activity) Haemophilia A (i.e. Factor VIII deficiency) or B (i.e. Factor IX deficiency)
- Dutch or French speaking
- Patients who provide their haemophilia treatment regimen to be stable (i.e. a regular treatment during the last 6 months, verified by the existing patients' logbook).
You may not qualify if:
- Patients suffering from known neuropathies with definite medical causes independent from the haemophilia (e.g. diabetes polyneuropathy)
- Patients with a haemarthrosis in the month preceding study participation will be excluded as well. In case of doubt, ultrasound will be used to check the presence of bleed in the joint.
