RESUMO
WHAT IS KNOWN AND THE OBJECTIVE: Low-grade evidence supports the use of newer biologics for otherwise refractory juvenile idiopathic arthritis (JIA)-associated uveitis, such as tocilizumab. CASE SUMMARY: This report details the cases of two adolescents whose severe JIA-associated uveitis was unresponsive to the first-line therapeutic approach. Tocilizumab therapy led to the remission of uveitis after a mean time of 3 weeks, and methotrexate was safely discontinued 1.5 years later. WHAT IS NEW AND CONCLUSION: To our knowledge, these are the first reports of successful methotrexate withdrawal during tocilizumab treatment of JIA-associated uveitis. The administration of tocilizumab without methotrexate could be considered in patients with JIA-associated uveitis unresponsive to conventional therapy.

PURPOSE: To evaluate the relation between CD34+ cells count in maternal blood and potential development of fetal congenital renal abnormalities. MATERIALS AND METHODS: We enrolled 16 women that gave birth to newborns carrying congenital renal malformations over a 3-year period and 48 women with uncomplicated pregnancies (controls) in a 1:3 ratio (three controls per case). RESULTS: CD34+ cells in the maternal peripheral blood were significantly lower in the group of women who gave birth to newborns carrying congenital renal malformations compared to the controls (p < .0001). CONCLUSIONS: CD34+ cells in maternal blood could be validated as a potential marker to predict the development of possible kidney malformations.
