Abstract:
Objective To investigate the clinical features of neuromyelitis optica spectrum disorders(NMOSD)with connective tissue diseases(CTD). Methods Clinical data of 16 NMOSD-CTD patients and 54 NMOSD patients admitted to the Second Affiliated Hospital of Fujian Medical University from January 2015 to February 2020 were collected.The initial symptom,intracranial lesion,spinal cord lesion,laboratory examination and treatment response were compared between the two groups. Results The incidence of Sjögren's syndrome(SS)was the highest(10/16,62.5%)in NMOSD-CTD group.The NMOSD-CTD group had significantly higher positive rate of aquaporin-4 immunoglobulin G(AQP4-IgG)in serum or cerebrospinal fluid(100% vs. 70.2%,P=0.009),higher positive rates of serum anti-nuclear antibodies,anti Sjögren's syndrome A antibodies and anti-Ro52 autoantibodies(P<0.001),as well as higher proportion of patients with the expanded disability status scale score ≥ 6(50.0% vs. 22.2%,P=0.035)than the NMOSD group.There was no significant difference between the two groups in the age of onset,visiting age,recurrence frequency,disease course,distribution of intracranial lesions,spinal cord involvement,or the effective rate of glucocorticoid pulse therapy(all P>0.05).Conclusions NMOSD is often complicated with CTD,and SS is the most common one.The positive rate of serum or cerebrospinal AQP4-IgG and the seropositivity of several other autoantibodies in NMOSD-CTD patients were higher than those in NMOSD patients.Neurological impairment in NMOSD-CTD patients were severer,which should arouse attention of clinicians.
