Sjogren's Syndrome
"Persistent dry eyes that feel gritty, burning, or like there's sand in them"
What is Chronic Migraine?
Sjogren's syndrome is a chronic autoimmune disorder where the immune system mistakenly attacks the body's moisture-producing glands, primarily the lacrimal glands (tears) and salivary glands (saliva). This results in the hallmark symptoms of dry eyes (keratoconjunctivitis sicca) and dry mouth (xerostomia). Sjogren's can occur as a primary condition or secondary to other autoimmune diseases like rheumatoid arthritis or lupus. Beyond dryness, it can affect multiple organ systems including joints, lungs, kidneys, nerves, and blood vessels, significantly impacting quality of life.
Healthy Function
What your body should do
In a healthy individual, the lacrimal glands produce tears that lubricate, nourish, and protect the cornea through a complex three-layer tear film (lipid, aqueous, mucin). The salivary glands (parotid, submandibular, sublingual, and minor glands) produce 0.5-1.5 liters of saliva daily, containing enzymes (amylase, lipase), immunoglobulins (IgA), growth factors, and antimicrobial peptides. Saliva maintains oral pH, initiates digestion, protects teeth from decay, and facilitates speech and swallowing. The immune system maintains self-tolerance through central and peripheral mechanisms, preventing auto-reactive lymphocytes from attacking healthy tissue. Regulatory T-cells suppress inappropriate immune responses, and the balance of Th1, Th2, Th17, and Treg cells maintains immune homeostasis.
When Things Go Wrong
Signs of chronification
- Pain threshold lowers over time
- More frequent attacks
- Brain stays in alert mode
- Medication stops working
How This Develops
Understanding the biological mechanisms helps us target the root cause
Point 1
Understanding the mechanism helps us target the root cause rather than just treating symptoms.
Recognizing All Symptoms
Chronic migraine affects multiple systems. Understanding your symptoms helps us identify the underlying mechanisms.

Conditions That Occur Together
These conditions often coexist with chronic migraine due to shared mechanisms
Rheumatoid Arthritis (Secondary Sjogren's)
30-50% of RA patients develop secondary Sjogren's; shared autoimmune pathways; both involve synovial and glandular inflammation; HLA associations overlap
Systemic Lupus Erythematosus (SLE)
15-20% of lupus patients have secondary Sjogren's; shared anti-SSA/SSB antibodies; both have Type I interferon signature; female predominance
Systemic Sclerosis (Scleroderma)
Frequent overlap; both affect exocrine glands; Raynaud's common to both; shared autoimmune features
Hashimoto's Thyroiditis
Common comorbidity; shared autoimmune predisposition; both organ-specific autoimmune diseases; thyroid dysfunction worsens fatigue

HIV positive; diffuse infiltrative lymphocytosis syndrome (DILS); different lymphocyte subsets (CD8+ predominant)
Amyloidosis
Dryness, macroglossia, organ involvement
Congo red positive deposits; monoclonal protein; tissue biopsy shows amyloid; different underlying mechanism
What's Driving Your Migraines
Identifying the underlying causes allows us to target treatment effectively

Molecular mimicry hypothesis; EBV DNA found in salivary glandsEBV serology; history of infectious mononucleosis; elevated viral loads
Cytomegalovirus (CMV) and Other Viruses
Viral triggers may initiate autoimmune responseCMV serology; hepatitis C testing; HIV testing to rule out mimics
Hormonal Factors (Estrogen)
9:1 female-to-male ratio; often triggered postpartum or perimenopauseHormone panel; pregnancy history; menopausal status
Environmental Toxins
Silica exposure increases risk; occupational hazardsOccupational history; silica, solvent, pesticide exposure
Gut Microbiome Dysbiosis

Time Matters
Don't wait for symptoms to worsen. Early intervention leads to better outcomes.
How is Chronic Migraine Diagnosed?
Comprehensive evaluation to identify triggers, contributing factors, and appropriate treatment
Anti-SSA/Ro and Anti-SSB/La Antibodies
Purpose:
Primary serologic markers for Sjogren's
Anti-SSA in 60-70%, anti-SSB in 40-50%; highly specific when both present; associated with systemic features and neonatal lupus risk
ANA (Antinuclear Antibodies)
Purpose:
Screen for autoimmune disease
Positive in 70-90%; speckled pattern most common; supports but does not confirm diagnosis
Rheumatoid Factor (RF)
Purpose:
Additional autoantibody marker
Positive in 50-70%; associated with more severe disease and lymphoma risk
Schirmer's Test
Purpose:
Objective measure of tear production
Filter paper placed in lower eyelid; <5 mm wetting in 5 minutes strongly suggestive; 5-10 mm borderline
Rose Bengal or Lissamine Green Staining
Purpose:
Assess corneal and conjunctival damage
Stains devitalized epithelial cells; pattern of staining indicates dry eye severity
Salivary Flow Rate (Sialometry)
Purpose:
Measure unstimulated saliva production
<0.1 mL/min abnormal; objective confirmation of xerostomia
Salivary Gland Scintigraphy
Purpose:
Functional imaging of salivary glands
Technetium-99m uptake and secretion; reduced uptake indicates glandular dysfunction
Parotid Sialography
Purpose:
Anatomical imaging of ductal system
Ductal dilation, strictures, punctate sialectasis (sausage-link appearance)
Labial Salivary Gland Biopsy
Purpose:
Gold standard diagnostic test
Focal lymphocytic sialadenitis with >50 lymphocytes per 4 mm2; focus score >=1 diagnostic; assesses severity and lymphoma risk
Ocular Surface Staining (Fluorescein)
Purpose:
Assess tear film stability and corneal integrity
Corneal epithelial defects; tear break-up time <10 seconds abnormal
Serum Immunoglobulins and Protein Electrophoresis
Purpose:
Assess for hypergammaglobulinemia and monoclonal spikes
Polyclonal IgG elevation common; monoclonal spikes require lymphoma workup
ESSDAI (EULAR Sjogren's Syndrome Disease Activity Index)
Purpose:
Quantify systemic disease activity
Composite score across 12 domains (cutaneous, renal, joint, etc.); guides treatment decisions
Supporting Your Treatment
Evidence-based lifestyle modifications to enhance treatment effectiveness
Anti-inflammatory Mediterranean diet: olive oil, fatty fish, vegetables, fruits
Omega-3 fatty acids: reduce inflammation, support tear production
Hydration: sip water constantly; carry water bottle; avoid caffeine and alcohol
Moist foods: soups, stews, sauces make swallowing easier
Chewing sugar-free gum or xylitol mints: stimulates saliva
Avoid: spicy, acidic, salty foods that irritate dry mouth
Avoid: dry, crumbly foods (crackers, toast) without liquids
Limit: caffeine and alcohol (worsen dryness)
Vitamin D: essential for immune regulation (maintain 60-80 ng/mL)
Antioxidant-rich foods: berries, leafy greens combat oxidative stress
