Recent findings, new classification criteria and treatment guidelines, and concerted efforts by various organizations to provide educational resources are among a number of factors improving the outlook for patients with primary Sjögren’s syndrome, according to Judith James, MD, PhD.
Additionally, the number of studies of primary Sjögren’s syndrome (pSS) is increasing, albeit slowly, and ongoing studies of biologics are showing promise, Dr. James said during a clinical update at the Winter Rheumatology Symposium sponsored by the American College of Rheumatology.
Classification criteria
The ACR in conjunction with the European League Against Rheumatism (EULAR) published new criteria for pSS classification in 2016 based on the available evidence and expert consensus. Inclusion criteria include daily, persistent, troublesome dry eyes for more than 3 months, recurrent sensation of sand or gravel in the eyes, use of tear substitutes more than three times each day, frequent drinking of liquids to aid in swallowing dry food, or at least one EULAR Sjögren’s syndrome disease activity index (ESSDAI) domain with a positive item. Exclusion criteria include prior head and neck radiation treatment, polymerase chain reaction–confirmed active hepatitis C infection, AIDS, sarcoidosis, amyloidosis, graft-versus-host disease, or IgG4-related disease, said Dr. James, professor and chair of the arthritis and clinical immunology research program at the University of Oklahoma, Oklahoma City (Arthritis Rheumatol. Jan 2017;69[1]:35-45).
- A score of 4 or higher in patients who meet the inclusion criteria and do not have any of the exclusion criteria leads to classification with pSS, based on the following findings:
- Labial salivary gland with focal lymphocytic sialadenitis and focus score of at least 1 foci/4 mm2 (weight/score = 3).
- Anti-SSA/Ro-positivity (weight/score = 3).
- Ocular Staining Score of at least 5, or van Bijsterveld score of at least 4, in at least one eye (weight/score = 1).
- Schirmer’s test of no more than 5 mm/5 min in at least one eye (weight/score = 1).
- Unstimulated whole saliva flow rate of no more than 0.1 mL/min (weight/score = 1).
Clinical pearls for detection and management
In Dr. James’ experience, the three symptoms (taken together) with the highest predictive value for diagnosing pSS are dry mouth, sore mouth/tongue, and dry eyes. About 25% of Sjögren’s patients may have no detectable salivary flow, she said.
Dry, cracked skin that can lead to secondary infections is another common issue affecting about 55% of patients.
“So we always have to talk to our Sjögren’s patients about skin,” she said. “We also have recurrent sinusitis, chronic cough, dyspepsia, constipation, and other symptoms.”
Concurrent autoimmune diseases are another concern in Sjögren’s patients, she said. One to particularly keep in mind, in addition to lupus and rheumatoid arthritis, is autoimmune thyroid disease.
Data suggest that up to 45% of Sjögren’s patients have thyroid dysfunction, and if you look at just those with autoimmune thyroiditis, their risk of Sjögren’s is increased 10-fold vs. those without autoimmune thyroiditis, she said.
Other conditions to keep in mind when it comes to diagnosing and managing patients, as has been shown in numerous studies over the years, include Raynaud’s phenomenon, which affects at least 13% of patients, and subclinical muscle inflammation, which affects more than 50% of patients, Dr. James said.
“Depression ... as well as anxiety, is quite common in Sjögren’s patients, and fatigue is profound,” she added, noting that fatigue is “the No. 1 issue” for many patients.
Another area of particular concern in Sjögren’s is the increased risk of lymphoma, she said.
Studies show varying rates of lymphoma in Sjögren’s, with one suggesting a 44-fold increased risk, but this is likely only among those at very high risk. Other studies suggest the increase is risk overall is in the range of 4- to 10-fold, she said.
Mortality in Sjögren’s patients
A 2015 study by Soledad Retamozo et al. showed that the presence of cryoglobulinemic vasculitis (CV) at diagnosis is associated with increased mortality risk.
Of 515 consecutive pSS patients with a mean follow-up of 110 months, 65 (12%) had cryoglobulins detected, and 21 of those (32%) fulfilled CV criteria. The patients with cryoglobulins had higher cumulative mean disease activity, 45 (9%) developed B-cell lymphoma, and 33 (6%) died (Arthritis Rheumatol. 2015;67[suppl 10]. Abstract 628).
Additionally, both CV-positive and CV-negative patients had higher risk of B-cell lymphoma, but the risk was greatest in the CV-positive group (hazard ratios, 7.47 and 2.56, respectively), and the CV-positive patients had a higher risk of death (HR, 11.68).
“This actually has changed practice in our Sjögren’s clinic because we didn’t used to do cryos on everybody unless they had leukocytoclastic vasculitis, because they also have a higher risk of death,” Dr. James said.
Systemic activity also predicts pSS mortality, according to findings published in 2016 by Pilar Brito-Zerón et al. Of 1,045 patients who were part of the Spanish Group of Autoimmune Disease-SS Study Group and who were followed for a mean of 117 months, mortality was 11%. Survival was 96% at 5 years, 90% at 10 years, 81% at 20 years, and 60% at 30 years (Ann Rheum Dis. 2016;75:348-55).
Baseline factors associated with increased mortality on multivariate analysis included male gender, cryoglobulins, and low complement levels; the strongest model for death included high activity in at least one ESSDAI domain, baseline ESSDAI of at least 14, more than one laboratory predictive marker such as lymphopenia, anti-La, monoclonal gammopathy, low C3, low C4, and/or cryoglobulins.
Predicting progression to pSS
Progress has also been made with respect to predicting progression to pSS among patients who present with some related symptoms but don’t meet Sjögren’s criteria, Dr. James noted.
A 2017 study by Caroline Shiboski et al. looked at 771 patients from the Sjögren’s International Collaborative Clinical Alliance (SICCA) registry who had previously had objective measures of salivary hypofunction, dry eyes, focal lymphocytic sialadenitis or anti-Ro/anti-La. When these patients were recalled 2-3 years after their baseline evaluation, 28 (9%) of 308 patients who did not meet pSS criteria at baseline had then progressed to pSS (Arthritis Care Res. 2017;70[2]:284-94).
Those with baseline hypergammaglobulinemia were four times more likely to progress, and those with baseline low complement levels were six times more likely to progress.
Many patients will present with symptoms, but won’t ever develop Sjögren’s, but the subset of patients with these baseline characteristics may be at greater risk, she said.
Autoantibodies and pathogenesis
Up to 90% of pSS patients will have one or more of anti-Ro, anti-La, or rheumatoid factor, and many will have a positive antinuclear antibody (ANA) level of at least 1:320, Dr. James said, adding that anti-Ro and anti-La are linked with earlier disease onset, increased disease severity, longer disease duration, and extraglandular involvement.
Ro52, a target of Sjögren’s autoantibodies, may also confer more severe disease, and autoantibodies to muscarinic acetylcholine receptors appear to contribute to pathogenesis in Sjögren’s patients “above and beyond what we see with lymphocytic infiltrates and other things that are happening in the salivary gland,” she said.
Other exciting progress with respect to disease pathogenesis includes an increased focus on genetics and genetic predisposition beyond human leukocyte antigen associations.
Mutations in genes that overlap with Sjögren’s and lupus or Sjögren’s and RA, such as IRF5, Blk, and STAT4 appear to contribute to Sjögren’s syndrome development.
“And then there’s also some new genetics looking at Sjögren’s-specific genes, and these may help us as we think about new targetable pathways in this disorder,” she said.
Genomics and gene-environment interactions, such as interactions with viral infections or “other things that lead to molecular mimicry that get the disease process started,” are also getting increased attention; gene-expression profiling has shown overlap between Sjögren’s and lupus (shared genetics, autoantibodies, and similarly strong interferon signatures, for example), which isn’t surprising.
“But we’re also seeing NF-kB [NF-kappa B] activation, antigen presentation, and migration pathways that are being found in Sjögren’s that aren’t necessarily the ones that we see in lupus,” she added.
Clinical practice guidelines
A number of practice guidelines addressing various symptoms and issues associated with pSS have been released in the last few years, including several from EULAR, the United States, Brazil, and the United Kingdom, are summarized and reviewed in a recent paper by Vasco Romão et al. (RMD Open. 2018;4:e000789. doi: 10.1136/rmdopen-2018-000789).
The British Society of Rheumatology guideline, which came out about a year ago, has particularly practical guidance on the management of dryness and systemic disease, she said (Rheumatology. 2017;56[10]:1643-7).
The increasing focus on pSS research has important implications both for trial design and patient care, especially in light of the new classification criteria, practice guidelines, and educational resources provided by organizations such as the Sjögren’s Syndrome Foundation (including videos, health care provider information, and downloadable brochures and resource sheets) and the European Research Network’s ReCONNET Disease Info Toolbox for Sjögren’s, Dr. James concluded.
Dr. James reported having no disclosures.

Of 515 consecutive pSS patients with a mean follow-up of 110 months, 65 (12%) had cryoglobulins detected, and 21 of those (32%) fulfilled CV criteria. The patients with cryoglobulins had higher cumulative mean disease activity, 45 (9%) developed B-cell lymphoma, and 33 (6%) died (Arthritis Rheumatol. 2015;67[suppl 10]. Abstract 628).
