Autoantibodies to Cytosolic 5′-Nucleotidase 1A in Primary Sjögren’s Syndrome and Systemic Lupus Erythematosus

@lupuscyclopedia @MymaAlbaydaMD Diagnosis of sIBM should not be done based on anti-cN1A, as it is quite often positive in SLE and Sjogren and not associated with IBM. If IBM is suspended in that case a biopsy is necessary always. https://t.co/584JbJv4ux

Agree with you. It has to be used with utmost caution.

@docrota It is available on the latest EuroImmun lineblot. Having said this, it isn't required to diagnose IBM and I would urge caution regarding using CN1A in this way given the frequent occurrence in other diseases: https://t.co/JHcm4dw0tB
