New guidelines to manage peripheral neuropathy related to Sjögren disease have been developed by a multidisciplinary team of physicians from across medicine.
The guidelines will provide an evidence-based resource for the assessment, diagnosis, and treatment of various peripheral neuropathies related to the disorder.
Up until now, the field has been “haphazard and chaotic,” lead author George Sarka, MD, DrPH, MPH, director of the CME Committee for MemorialCare, Saddleback Medical Center, Laguna Hills, California, and member of the Sjögren Foundation PNS Guidelines Topic Review Group (TRG), told this news organization.
Dr. Sarka discussed the initiative at the American Academy of Neurology 2024 annual meeting.
Severe, Complex Illness
Sjögren disease is the second most common autoimmune rheumatic disorder after rheumatoid arthritis, affecting an estimated 4 million Americans. Women make up most of the patient population at a ratio of 9:1.
The condition typically affects the mucous membranes and moisture-secreting glands of the eyes and mouth, resulting in decreased tears and saliva. But peripheral nervous system (PNS) manifestations often precede these symptoms and can occur in up to 60% of Sjögren disease cases.
“Traditionally, Sjögren’s was looked at as a dry eye and dry mouth disease, but we realize now that it’s so much broader than that,” said Dr. Sarka. “It’s a severe, systemic, and complex illness that can affect any body organ or system, and the nervous system is frequently affected.”
PNS manifestations cause more than mere discomfort; they can lead to diagnostic and management challenges, costly treatments, and diminished quality of life.
Getting a proper diagnosis goes a long way toward improving the quality of life for these patients, Steven Mandel, MD, clinical professor of neurology at the Zucker School of Medicine at Hofstra-Northwell, adjunct clinical professor of medicine at NY Medical College, New York City, and member of the TRG, told this news organization.
The problem is, doctors don’t always think an autoimmune disorder is causing the symptoms, said Dr. Sarka. “There’s an old adage in neurology that if you don’t think about it, you’re going to miss it; you have to ask, and that’s what we’re trying to get people to do.”
The condition often accompanies other immune system disorders such as rheumatoid arthritis and lupus. But as patients are referred back and forth between ophthalmologists, rheumatologists, and neurologists, the condition is often missed. “It could be 4 or 5 years before a definitive diagnosis of Sjögren’s is made,” said Dr. Sarka.
He believes the education system is partly to blame. “Medical schools have been very deficient in teaching people about recognizing Sjögren disease.”
That leaves many physicians at a loss about “what to do with these patients when they walk in the door,” said Dr. Mandel. “They don’t know how to manage them; they don’t know how to diagnose them; and they don’t know how to treat them.”
Developing guidelines with multispecialty collaboration was “absolutely critical” in addressing this knowledge gap, Dr. Mandel added. That process involved “a very rigorous and transparent methodology so that it would be accepted by all the professionals involved in Sjögren’s,” he said.
The process took 3 years and involved amassing and grading the evidence, getting consensus from committee members, developing recommendations, and getting feedback and external review.
