  1. 11/6/2014 Andrew H. Murr, MD Professor and Chairman Roger Boles, MD Endowed Chair in Otolaryngology Education Department of Otolaryngology- Head and Neck Surgery Sialadenitis without Stones: RAI, Autoimmune, and Management UCSF Sialendoscopy/Salivary Duct Surgery Course November 6, 2014 University of California, San Francisco Sialadenitis without Stones Case • 43 year old female • Bacterial sialadenitis • Bilateral Parotid • Radioactive Iodine (RAI) effects swelling • Autoimmune Disease • In tact VIIth nerve 1/6 • Other • No discrete mass 1

  2. 11/6/2014 Bacterial Differential Diagnosis of Gland Enlargement: Is there pus in the duct? Sialadenitis Yes No • Erythema Bacterial Sialadenitis Other categories • Tenderness • Pus in duct • Dehydrated • Diabetic • Elderly • Often unilateral • “Surgical Parotitis” Salivary Duct Stenosis RAI Koch et al., Arch OHNS, Sept., 2012 Types Causes • RadioActive Iodine Sialadenitis • Inflammatory • Allergic • Web associated • Infectious • Fibrous • Granulomatous • RAI associated • Autoimmune 2

  3. 11/6/2014 Radioiodine (I131) Papillary Thyroid Carcinoma • Key treatment modality for management of benign and malignant thyroid disease • Utility is due to propensity of thyroid follicular cell uptake • I 131 beta emissions cause cellular necrosis Increasing incidence of differentiated thyroid cancer I 131 Radiation Sialadenitis in the United States, 1988-2005 Chen A. et al; Cancer, 2009 • Salivary glands also concentrate iodine through selective sodium/iodine symporter • Symporter most prevalent in ductal epithelial cells • I 131 creates a dose-related injury to salivary glands • Serous glands and acini are more susceptible than mucinous acini: Parotid = serous • Parotid gland more affected than submandibular or sublingual salivary glands 3

  4. 11/6/2014 I 131 Radiation Sialadenitis Morbidity and Quality of Life • I 131 injury causes: • Dingle et al: OHNS, May, 2013 - acute and chronic inflammation n = 145 well-differentiated thyroid cancer patients - duct lumen narrowing and stricture formation - altered saliva, mucous plugs • Dose dependent increase in sialadenitis • Salivary stagnation; obstructive symptoms ( >150mCi I131 2.47 times more likely) • Pain, gland swelling; exacerbated by meals • Xerostomia, taste alteration • Reduced oral and overall QOL if received >150mCi I131 • Clinical incidence and severity variable Incidence – I 131 Sialadenitis Prevention –Lack of consensus Van Nostrand; Oral Dis, 2011 Van Nostrand, Oral Diseases, 2011 • Variable • Hydration • Sialagogues • Discontinuation of anticholinergic meds • Gland massage • Anti-inflammatory meds • Cholinergic meds 4

  5. 11/6/2014 Pale mucosa with ductal stenosis, Therapy ductal debris and mucous plugs • Medical – Hydration – Gland massage – Heat – Anti-inflammatory medication – Cholinergic medication • Interventional – Sialendoscopy – Sialadenectomy Technique Post-irrigation Gland Swelling •Introduction of diagnostic sialendoscope •Ductal lumen inspected thoroughly •Duct flushed with copious saline irrigation •Confirmation of gland engorgement 5

  6. 11/6/2014 I 131 Radiation Sialadenitis - I 131 Radiation Sialadenitis - Sialendoscopy Sialendoscopy • Nahlieli, Nazarian; Oral Diseases, 2006 • De Luca et al; Br J OMFS, 52(7), 2014 n=15 n=30 (100 mg hydrocortisone) (“hydrocortisone solution” irrigation) 100% symptom-free 77% improved symptoms f/u 2wks – 84 months • Kim et al; Laryngoscope, 117, 2007, 133-136 n=6 50% symptom-free • Bomeli et al; Laryngoscope, 2009 n=12 (40 mg triamcinolone in 5cc NSS) 75% improved symptoms Prendes et al. Arch OHNS, 2012 Pre-treatment Patient Characteristics Prendes, B. L. et al. Arch Otolaryngol Head Neck Surg 2012 11 patients - all patients had previously attempted and failed conservative management - 7/11 (64%) of patients had been treated with a least one course of antibiotics for an episode of presumed bacterial sialadenitis - median time after I 131 16 months 6

  7. 11/6/2014 Treatment Results Proposed Mechanisms of Benefit • Instrument dilation of papilla and duct • Saline hydraulic dilation of ductal system • Flushing of debris from duct • Additional benefit of steroid irrigation and dosing of steroid irrigant is unclear Summary Autoimmune Sialendoscopy for I 131 induced sialadenitis • • Sjogrens provides therapeutic benefit for most patients with symptoms recalcitrant to conservative medical therapy • Effective in providing a sustained period of patient-reported improvement in symptoms • Further experience with this treatment modality, its timing, and long-term outcomes data are needed 7

  8. 11/6/2014 Sjogren’s Syndrome Sjogren’s Syndrome Primary Secondary: • Inflammation of salivary • Associated with connective tissue disease- glands • RA • Lacrimal gland involved • SLE • Keratoconjunctivitis • Scleroderma sicca • Dermatomyositis Sjogren’s Work-up Sjogren’s Imaging Primary Secondary • SSA and SSB • ESR • SS rho and SS la • ANA • “Sjogrens Antibodies” • RF • CBC • EBV • Quantitative immunoglobulins 8

  9. 11/6/2014 Salivary Gland Biopsy Primary Sjogren’s: 20 Years Gomes, JOMFS, Jan-Mar, 2012 • Minor salivary gland – ~50% sensitivity • Parotid tail biopsy – ~100% sensitivity Other-viral: Mumps Sjogrens Treatment • Symptomatic treatment Systemic treatment • Corticosteroids/antibiotics • Xerostomia • Surveillance for non- – Dental caries Hodgkin lymphoma • Flouride • Dental hygiene – Artificial saliva – Sialogogues – Pilocarpine • Salagen – Role for Sialendoscopy with irrigation 9

  10. 11/6/2014 Other- viral: HIV Other • Pneumoparotitis • Alcoholism • Bulemia • Sarcoid OHNS Faculty and Residents Conclusion Sialendoscopy with or without steroid irrigation can be a diagnostic and therapeutic treatment in cases of: • RAI sialadenitis • Sjogren’s • HIV Differential includes: • Viral and other pathologies 10
