title: Increased levels of serum IgE in children of mothers with systemic lupus erythematosus.
abstract: Various allergic diseases have been described in patients with systemic lupus erythematosus (SLE). In the present study, we evaluated the prevalence of allergic disease and serum IgE levels in 36 children of 26 mothers with SLE. None of the subjects had any rheumatic symptoms. There was at least one type of allergic disease in 28 (78%) of the 36 children of mothers with SLE, as compared with 30% in Japanese control children (P < 0.01). The prevalence of atopic dermatitis and bronchial asthma was higher in children of mothers with SLE (64% and 28%) than in controls (19% and 9%) (P < 0.01, respectively). Fourteen of the 36 subjects (39%) had higher levels of serum IgE than those of normal range for age-matched healthy Japanese children with no atopic family disease in the immediate family history, and these children had atopic disease. Among the 14 children with high serum-IgE levels, seven had neither immediate nor remote family history of atopic disease, while the others had an immediate family history of atopic disease. We think that genetic factors may influence the presence of allergic disease in children of mothers with SLE, and that the increased serum IgE levels in children of SLE mothers with no allergic family history may be a part of subclinical immunologic abnormalities related to SLE.
