Clinical characteristics of cerebral venous sinus thrombosis in childhood-onset systemic lupus erythematosus patients: a single-centre study from China.

OBJECTIVES Cerebral venous sinus thrombosis (CVST) is a rare complication of childhood-onset SLE (cSLE) and is potentially fatal to the patient. In order to better define the characteristics of CVST in cSLE, we analysed a single-centre study of cSLE presenting with CVST. METHODS Clinical characteristics and laboratory findings of cSLE patients complicated with CVST from January 2006 to December 2019 were analysed through this retrospective, single-centre study. RESULTS A total of 1395 records of cSLE patients were reviewed. Five patients (0.36%) had CVST. Headache (80%) was the most frequent symptom. The transverse sinus (45%) was the most frequent location of thrombus, followed by the sigmoid sinus (27%). The SLE disease activity index (SLEDAI) at the time of CVST was 11±3. The D-dimer was elevated in all 5 cases, only one patient was positive for ACL and anti-β2GP-I IgM. All the patients underwent MRV screen to confirm the diagnosis. All the patients had a favourable outcome after receiving glucocorticoid and immunosuppressant treatment, as well as anticoagulant therapy. CONCLUSIONS CVST is relatively rare in cSLE and tends to occur in active lupus patients. Severe and persistent headache is an index of CVST. Early diagnosis and more intensive therapy for SLE, combined with anticoagulation therapy, could significantly improve the prognosis of CVST in cSLE.
