Duration of inactive disease while off disease-modifying anti-rheumatic drugs seems to influence flare rates in juvenile idiopathic arthritis: an observational retrospective study.

BACKGROUND: many Juvenile Idiopathic Arthritis (JIA) patients reach inactivity while medicated, but there are no guidelines to determine the moment or method for discontinuing medications. We present the flare rates and remission and possible influencing factors after therapy discontinuation in children with JIA. METHODS: data was collected from charts of JIA patients (n=70) in remission on medication, who had their drugs withdrawn. RESULTS: Seventy patients fulfilled inclusion criteria and were included for analysis. The mean time of inactive disease on medication until tapering or withdrawal was 15.6±6.7 months; 45 (64.3%) patients remained in remission and 25 (35.7%) flared. There was no difference between groups regarding sex, age, JIA subtype, disease duration, time in remission on medication and scheme of therapy withdrawal. Patients who fulfilled Wallace criteria for remission off medication had lower flare rates than those who did not achieve 12 months of remission after the medication withdrawal (p<0.0001). Patients who used biologic DMARDs plus synthetic DMARDs appeared to flare more (77.8% vs 29.5% respectively, p=0.008) and presented shorter periods of inactivity off medication (15.3±24.7 vs 32.3 ± 31.7 months respectively, p=0.049) compared to those who used only synthetic DMARDs. CONCLUSION: It is possible that gradual drug tapering is not necessary for JIA patients, but caution must be exerted in those patients using biologic DMARDs, weighing carefully the decision to withdraw medication, due to their higher flare rates and shorter times of inactive disease after the medication withdrawal.

Bilateral frosted branch angiitis in an initial case of systemic lupus erythematosus.

Frosted branch angiitis is a rare and severe form of retinal vasculitis. It may be idiopathic or arise secondary to a systemic disease. We have reported here an unusually severe case of frosted branch angiitis in a previously healthy 13-year old girl who presented with significantly reduced vision in both eyes. In this case, frosted branch angiitis was one of the presentations of systemic lupus erythematosus. The characteristic patterns of frosted branch angiitis were observed on fundoscopy in both eyes. An extensive etiological study was conducted, whereby the diagnosis of systemic lupus erythematosus was confirmed. Only a few such cases have been reported so far in the literature.

In this case, frosted branch angiitis was one of the presentations of systemic lupus erythematosus. The characteristic patterns of frosted branch angiitis were observed on fundoscopy in both eyes.

RESUMO A angeíte congelada é tipo específico de vasculite retiniana rara e grave. Pode ser idiopática ou secundária à doença sistêmica. Relatamos um incomum caso com associação ao lúpus eritematoso sistêmico, sendo a angeíte congelada uma das manifestações do quadro. Uma jovem de 13 anos, previamente hígida, apresentou queixa de baixa visual importante bilateral. À fundoscopia foi evidenciado o aspecto de angeíte de vasos congelados em ambos os olhos. Extensa investigação etiológica foi realizada com diagnóstico confirmado de lúpus eritematoso sistêmico. Poucos casos foram descritos na literatura.
