ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of allergic rhinitis (AR) and its intervention on disease condition and medications in patients with juvenile-onset systemic lupus erythematosus (JSLE).</p><p><b>METHODS</b>The clinical data of 96 children diagnosed with JSLE were collected, and according to the presence or absence of AR or other allergic diseases, they were divided into AR group (n=44), non-AR group (n=20), and non-allergic group (n=32). The children in the AR group were randomly administered with or without intervention (n=22 each). All the children were given standard JSLE treatment. The systemic lupus erythematosus disease active index (SLEDAI) and application of hormones and immunosuppressants were compared between groups.</p><p><b>RESULTS</b>The AR and non-AR groups had significantly higher SLEDAI scores, daily cumulative doses of glucocorticoids, and number of types of immunosuppressants used than the non-allergic group before treatment (P<0.05), while there were no significant differences between the AR and non-AR groups (P>0.05). After one month of treatment, the AR group with intervention had significantly lower SLEDAI scores and daily cumulative doses of glucocorticoids than the AR group without intervention (P<0.05), while there was no significant difference in the application of immunosuppressants between these two groups (P>0.05). After 3 and 6 months of treatment, the AR group with intervention had significantly lower SLEDAI scores, daily cumulative doses of glucocorticoids, and number of types of immunosuppressants than the AR group without intervention (P<0.05).</p><p><b>CONCLUSIONS</b>JSLE combined with allergic diseases such as AR has an adverse effect on disease condition and treatment, and the intervention for AR helps with the control of JSLE.</p>
