Relationship between joints bleeding and joint assessment in children with severe haemophilia A / 中华实用儿科临床杂志

ABSTRACT

Objective:To understand the relationship between joint bleeding and joint disease in hemophilia children, and to provide a theoretical basis for clinical treatment and prognosis.Methods:The patients with severe hemophilia A between 1 and 7 years old and with relevant nodal bleeding records were selected.All the patients admitted in Beijing Children′s Hospital, Capital Medical University, and Chengdu New Century Women′s and Children′s Hospital since June 2016 to January 2017.All the joint bleeding of each child was taken as the study joint, and the joint bleeding was collected during the last 3 months.The joints were assessed by using ultrasound, X-ray, magnetic resonance imaging(MRI) and Hemophilia Joint Health Score (HJHS) scoring systems.The correlation analysis was conducted between the joint bleeding, ultrasound, X-ray, MRI and HJHS scores.The correlation analysis was conducted for baseline ultrasound, X-ray, MRI and HJHS scores.Results:(1) There were 18 patients enrolled.The mean age was (5.6±1.8) years old.There were 30 joints bleeding in the observation period in total, with the annul median joint bleeding times of 4 (4-16 times), and the annul median target joint bleeding times of 8 (4-16 times). (2) Joint bleeding times of was correlated with ultrasound and X-ray evaluation ( r=0.390, P=0.033; r=0.517, P=0.008), and not correlated with HJHS or MRI(all P>0.05). (3) There was significantly positive correlation among ultrasound, X-ray, HJHS and MRI [ r=0.815(ultrasound vs.X-ray), r=0.510(ultrasound vs.HJHS), r=0.812(ultrasound vs.MRI), r=0.666(X-ray vs.HJHS), r=0.911(X-ray vs.MRI), r=0.781(HJHS vs.MRI), all P<0.01]. (4) There was no correlation between times and assessment for joints whose ultrasound and /or MRI in joints with abnormal ultrasound and /or MRI evaluation( P>0.05). Conclusions:The results of joint bleeding and joint evaluation are inconsistent.Joint bleeding can not truly reflect the situation of joint diseases.The assessment of hemophilia should include comprehensive evaluation of joint structure, function, activity ability and other aspects to guide the treatment of haemophi-lia children.
