Abstract

Introduction & Aims: Haemophilic arthropathy (HA) is a major complication in patients with haemophilia (PWH), but the study of age-specific prevalence and severity of HA is very limited in Asian countries. Materials & Methods: This study retrospectively reviewed 146 severe- and moderate-type Taiwanese PWH aged 4–73 years, with roentgenograms of elbows, knees and ankles and calculated Pettersson scores. Results: The prevalence of HA, mean number of HAs per patient and mean Pettersson scores of all the joints were 42.8%, 1.3 and 1.9 points in PWH aged 4–10 years; 64.3%, 1.4 and 4.1 points in PWH aged 11–19 years; 97.1%, 2.9 and 15.6 points in PWH aged 20–29 years; 93.1%, 4.4 and 33.1 points in PWH aged 30–39 years; 100%, 5.1 and 46.1 points in PWH aged 40–49 years and 100%, 5 and 49.6 points in PWH aged ≥50 years, respectively. There was a high prevalence of HA for PWH aged ≥20 years. Among PWH aged <20 years, prevalence of HA was low and mild ankle arthropathy was the most common. Besides, in the four age groups aged <40 years, the prevalence of ankle arthropathy was the highest, followed by elbow arthropathy and then knee arthropathy. Conclusions: Although severe arthropathy of the six major joints was rare in PWH aged <30 years, it increased rapidly in PWH after 30 years. Analysis of clinical correlates suggested that age, severity of haemophilia, absence of prophylaxis and presence of HCV infection correlated positively with Pettersson scores.
