Well lets start with white matter lesions. VERY common in anybody over the age of 50 and not uncommon under the age of 50. In general mean nothing unless accompanied by some rather significant ANA counts. (which would be SSA and SSB)
But lets talk numbers. The highest estimate for peripheral involvement with whats considered "Primary SjS" is 5% while up to 50% may have cutaneous involvement. Less than 10% of the time are the skin erruptions are Vasculitis.
Up until 2012 with SICCA you had to have:
According to the American-European classification system ,diagnosis of primary Sjögren syndrome requires at least four of the criteria listed below; in addition, either criterion number 5 or criterion number 6 must be included. Sjögren syndrome can be diagnosed in patients who have no sicca symptoms if three of the four objective criteria are fulfilled. The criteria are as follows:
- Ocular symptoms - Dry eyes for more than 3 months, foreign-body sensation, use of tear substitutes more than 3 times daily
- Oral symptoms - Feeling of dry mouth, recurrently swollen salivary glands, frequent use of liquids to aid swallowing
- Ocular signs - Schirmer test performed without anesthesia (< 5 mm in 5 min), positive vital dye staining results
- Oral signs - Abnormal salivary scintigraphy findings, abnormal parotid sialography findings, abnormal sialometry findings (unstimulated salivary flow < 1.5 mL in 15 min)
- Positive minor salivary gland biopsy findings
- Positive anti–SSA or anti–SSB antibody results
Secondary Sjögren syndrome is diagnosed when, in the presence of a connective-tissue disease, symptoms of oral or ocular dryness exist in addition to criterion 3, 4, or 5, above.
SINCE 2012 in the US anyway, we no longer distinguish between the two(we talk about it but that is it) except for some occular disease for which there is a blood test that a few try to apply to regular SjS:
According to the ACR criteria, the diagnosis of Sjögren syndrome requires at least two of the following three findings:
-
Positive serum anti-SSA and/or anti-SSB antibodies or positive rheumatoid factor and antinuclear antibody titer of at least 1:320
-
Ocular staining score of at least 3
-
Presence of focal lymphocytic sialadenitis with a focus score of at least 1 focus/4 mm2 in labial salivary gland biopsy samples
I don't even know where to begin. The chances of folk who have actual SjS having some of the things I see discussed on this site range from 1 in a hundred to 1 in 100,000.
I read a thread about vasculitis. In particular there was an article posted about Polyarteritis Nodosa which is a very serious large cell condition but has NO CONNECTION to SjS ever. First of all peripheral involvement only happens 5% of the . Less than 10% of the time are the skin eruptions Vasculitis (which BTW is very treatable) IF it is vasculitis, over 90% is small vessel vasculitis called Hyperglobulinemic purpura treated with a topical ointment.
SjS is a very unpleasant disease. It is life changing for many and usually associated with other autoimmune diseases. Knowledge is great but this constant attempt to find the worst is not support. There have been patients coming here reading a bit and immediately leaving because they are SCARED.
I am not dismissing the significance of SjS. I am one of those 35% of autoimmune disease sufferers that have SjS an additional gift, but for crying out loud lets keep it real.
Rituximab helps a lot of people, as does plaquenil along with a number of other meds. DO NOT try to make your experience someone elses.
