One child has since developed uveitis following completion of this study. JIA associated uveitis is usually a chronic Ku-0059436 solubility dmso anterior uveitis. It has a high complication rate, including visual loss, and requires regular ophthalmological screening depending on the JIA sub-type. The overall prevalence of uveitis in JIA

is 13%.[20] Patients with oligoarticular JIA have the highest rate of uveitis (20%).[20] Active uveitis does not usually correspond with active joint disease and joint disease can be well controlled or in remission and the uveitis can be active. It is difficult to draw any real conclusions from this observation given the sample size. However, it would seem that active uveitis in patients with JIA may contribute see more to the stress experienced by mothers. It also highlights the importance of factors

other than joint disease activity and functional status (as evidenced by the CHAQ) as promotors of stress. The findings of this study should be generalizable to all JIA cohorts as it reflects the spectrum of disease seen in clinical practice. Oligoarticular JIA is the most common sub-type accounting for 60% of JIA cases.[21, 22] This was similar in this study with 56% of mother’s having children with oligarticular arthritis. While these children often have a less severe disease course than those with other sub-types, the burden of JIA can be felt across all subtypes. As discussed, these patients are at increased risk of chronic uveitis, which could lead to an increase in stress despite inactive or low levels of joint disease activity. Higher levels of parental stress may have been demonstrated if this cohort had included only, or at

least predominantly, Masitinib (AB1010) polyarticular patients. However, we should not assume that because a patient has oligoarticular JIA that there is less stress experienced by the family. Weaknesses of this study lie in the fact that the sample was not of sufficient size to conduct comparisons between sub-types, gender or age and no details of duration of disease were collected to allow analysis of whether this factor impacted on maternal stress. The results of this study demonstrate that JIA is a chronic disease that can induce high levels of stress within carers. One-third of mothers reported stress levels in the range where professional help is recommended. This study supports the findings in previous studies on maternal and parental stress in JIA and reveals that stress levels are comparable to those reported in mothers of children with other chronic conditions. We must recognize the importance of addressing how the child and family are coping with the illness, and the child’s functional status, rather than focussing solely on improvements in clinical parameters. Further studies are required to identify factors that might alleviate this stress so that service provisions to such patients and their families can be further improved and targeted to this aspect of management.
