1 Palliative Management of Gastrointestinal Symptoms IGCE Session By Cora Pontee, MD Baylor Geriatrics February 6th, 2013

2 Common Gastrointestinal Symptoms in Palliative Patients Oral discomfort Dysphagia Nausea and vomiting Hiccups

3 Objectives To acquire knowledge of current evidence in managing GI symptoms To recognize oral discomfort and hiccups as treatable symptoms To apply principles of management of GI symptoms to clinical practice

4 Causes of Oral discomfort: Definitions Xerostomia : Dryness of the mouth resulting from diminished or arrested salivary secretion Dysgeusia : An impairment or dysfunction of the sensation of taste Stomatitis : The inflammation of the mucous lining of any structures of the mouth, which may involve the cheeks, tongue, gums, lips, and roof or floor of the mouth Mucositis : inflammation of a mucous membrane The Free Dictionary By Farlex

5 Causes of Oral discomfort Oral pain: angular stomatitis, dental caries, poorly fitting dentures, XRT or chemo induced stomatitis or mucositis, candidiasis, burning mouth syndrome Xerostomia: related to cancer (head and neck), dehydration, radiation, drug therapy (anticholinergic, psychotropic, opioid, cardiovascular) Dysgeusia: sinusitis or other infection, xerostomia, medications (antidepressants, HIV meds, chemotherapy), vitamin or mineral deficiency (zinc)

6 Denture stomatitis Definition: oral candidiasis that can occur in healthy adults wearing dentures May present as bleeding, swelling, burning sensation, xerostomia, or cacogeusia 35-50% of people wearing complete dentures Altarawneh et al, “Clinical and Histoligic Findings of Denture Stomatitis as Related to Intraoral Colonization Patterns of Candida albicans, Salivary Flow, and Dry Mouth,” J Prosthodont, 2012

7 Management of Oral Discomfort

8 Xerostomia treatment options Salivary substitute or oral gel every 1-2 hours or sugarfree gum Malic acid 1% spray Oral care: encourage family members to keep patient’s mouth moist (oral swabs to bedside) Increase liquid PO intake; try frozen juices, popsicles, ice chips, Resveratrol Pilocarpine 5 to 10 mg three times daily (watch for respiratory secretions or diarrhea) Gomez-Moreno G. et all, “Effectiveness of Malic Acid 1% in Patients with Xerostomia Induced by Antihypertensive Drugs,” Med Oral Patol Oral Cir Bucal 2012 Furness S et al, “Interventions for Management of Dry Mouth: Topical Therapies,” Cochrane Database Syst Rev 2011

9 ALTENS Acupuncture-like Transcutaneous Electric Nerve Stimulation 47 patients with cancer of the head and neck who were 3 to24 months from completing radiotherapy (mean age 60 years) with xerostomia Patients received twice weekly ALTENS sessions over 12 weeks Six month Xerostomia-Related Quality of Life Scale (XeQOLS) scores showed 86% of patients received a positive treatment response Now entering Phase 3 studies Wong RK et al, “Phase 2 Results from Radiation Therapy Oncology Group Study 0537: a Phase 2/3 Study Comparing Acupuncture-like Transcutaneous Electric Nerve Stimulation Verses Pilocarpine In Treating Early Radiation-Induced Xerostomia,” Cancer 2012, Sept 1

10 Mucositis: Physiology The Biology of Blood and Marrow Transplantation, Volume 11 Issue 12, Dec 2005

11 Treatment of Mucositis Chlorhexadine gluconate (Hibiclens, Betasept) Combination mouthwash preparations with: Diphenhydramine Lidocaine Loperamide Nystatin Tetracycline hydrocortisone Lidocaine 2% q4 to 8 hrs, 50/50 mixture with famotidine Sucralfate suspension swish and swallow q 3-4 times daily Doxepin oral rinse up to every 4 hours Opioids (topical, parenteral) Clarkson JE et al, “Interventions for Treating Oral Mucositis for Patients with Cancer Receiving Treatment,” Cochrane Database of Syst Rev, October, 2010

12 Laser Therapy in Mucositis 16 children (mean age 9.4 years) with chemotherapy-induced mucositis All children treated with GaAIAs diode laser with 830 nm wavelength, repeated every 48 hours until healing of lesion occurred On average 2.5 treatments in a period of 1 week were sufficient to heal the lesion; pain relief noted immediately after each treatment Cauwels RG and Martens LC, “Low level laser therapy in oral mucositis: a pilot study,” Eur Arch Paediatr Dent, 2011

13 Dysphagia Definition: Difficulty in swallowing or inability to swallow The Free Dictionary by Farlex

14 Dysphagia Oropharyngeal dysphagia Obstructing esophageal lesions Esophageal dysmotility (neuromuscular, autoimmune) Cognitive impairment

15 Oropharyngeal Dysphagia Upright positioning in bed, sitting at a table for meals Changing consistency of food (soft, pureed, thickened liquids) Careful hand feeding by caregivers Videofluoroscopy and Speech therapy consultation Deane K et al, “Dysphagia occurs frequently in Parkinson's disease although patients themselves may be unaware of swallowing difficulties. Speech and language therapists in conjunction with nurses and dietitians use techniques that aim to improve swallowing,” Cochrane Database of Syst Rev, Jan 2001.

16 Esophageal obstruction Surgical resection or laser ablation Placement of esophageal stent (SEMS) Placement of gastrostomy tube Help family cope with anxiety about patient’s poor PO intake Clarify goals of care Consider artificial nutrition and hydration Larssen L et al, “Long-term outcome of palliative treatment with self-expanding metal stents for malignant obstructions of the GI tract,” Scand J Gastroenterol, Oct 2012

17 Artificial Nutrition and Hydration (ANH) Finucane TE et al. Tube Feeding in Patients With Advanced Dementia: A Review of the Evidence. JAMA. 1999; 282(14) 1365-1370 Gillick MR. Rethinking the Role of Tube Feeding in Patients with Advanced Dementia. NEJM. 2000; 34 (3) 206-210

18 Nausea and Vomiting Definitions Nausea : A feeling of sickness in the stomach characterized by an urge to vomit Vomit (v): To eject part or all of the contents through the mouth, usually in a series of involuntary, spasmic movements The Free Dictionary by Farlex

19 Nausea and Vomiting

20 Diagnostic Work up Blood chemistries: calcium, sodium, BUN, creatinine, bilirubin Drug levels (theophylline, digoxin, anti-epileptic drugs) Neuroradiologic imaging to evaluate for sources of increased intracranial pressure or brainstem causes or vertigo and nausea Abdominal imaging HIDA scan

21 Nausea from GI tract Bowel inflammation or compression………………… ………………………………. Drugs (iron, NSAIDS, alcohol, antibiotics) Constipation Tube feedings (abdominal distention, diarrhea) Thick respiratory secretions, cough-induced vomiting Haldol (D, H1, M1), metoclopramide (D2), olanzapine (H1, M1) Stop drug, add PPI, H2 blocker Laxative, enema Reduce volume or change from bolus to continuous Nebulized saline, expectorant if cough reflex intact, anticholinergic if no cough reflex

22 Nausea from Chemoreceptor Trigger Zone Metabolic (renal, liver failure, or tumor products) Hyponatremia Drugs (opiates, chemotherapy, digoxin, carbemazepine, antibiotics, theophylline) Haldol (start at 0.5-1 mg q6 or q12), olanzapine Treat underlying etiology Decrease drug dosage or discontinue drug if possible

23 Nausea due to Vestibular etiology Middle ear infections Motion sickness …………………. Vestibular Antibiotics, decongestants Scopolamine (M1) or meclizine Meclizine, consider ENT consult Pullens B and van Bentham PP, “Intratympanic gentamycin for Meniere’s disease or syndrome,” Cochrane Database of Syst Rev 2011

24 Nausea due to bowel obstruction Therapeutic goal to manage symptoms in terminal patients (pain, cramps, nausea, emesis) Dexamethasone (may relieve malignant bowel obstruction) Transdermal scopolamine (slows gut, causes dry mouth, urinary retention, confusion) Glycopyrrolate (slows gut, causes dry mouth, urinary retention, confusion) Hyoscyamine (slows gut, causes dry mouth, urinary retention, confusion) Octreotide (expensive, reduces gut secretions)

25 Hiccups Definition: involuntary, intermittent, spasmodic contraction of the diaphragm and intercostal muscles. Muscle contraction results in a sudden inspiration and ends with abrupt closure of the glottis, thereby generating the characteristic ‘hic’ sound. Hiccups often occur with a frequency of 4 to 60 per minute, remaining relatively constant in a given individual. Lembo A, “Overview of hiccups”, Up to Date 2011

26 Hiccups Hiccup bout: lasts up to 48 hours Persistent hiccups: continues after 48 hours up to 1 month Intractable hiccups: continue longer than 1 month

27 Pathophysiology of hiccups Neural pathways of the hiccup reflex arc: Afferent limb of phrenic and vagus nerves and sympathetic chain Central mediator Efferent limb of phrenic nerve, nerve connections to glottis and inspiratory intercostal muscles Thought to involve the medulla oblongata, reticular formation of the brainstem, nuclei of phrenic nerve, and hypothalamus Image from Journal of Pain and Symptom Management, Vol 38, Sept 2009

28 Etiology Psychogenic gastric distension, aerophagia, sudden change in GI temperature Alcoholism, acute alcohol ingestion Arrhythmia-induced syncope (both cause and effect) Weight loss, insomnia

29 Etiology Foreign body adjacent to tympanic membrane Infections: pneumonia, pharyngitis Asthma CV: arrhythmia, MI, pericarditis, thoracic aortic aneurysm, PE Cerebral lesions, MS

30 Treatment options Non-pharmacological Pharmacological Surgical Calsina-Berna A et al, “Treatment of Chronic Hiccups in Cancer Patients: A Systematic Review,” Journal of Palliative Medicine, 2012

31 Non pharmacological treatment of hiccups Accupuncture Nebulized saline Folk remedies: Traction on the tongue Pressure over the eyebrow area Valsalva maneuver Drinking a glass of water through a straw Breath holding Sudden fright Irritation of the vagus nerve by supraorbital pressure or carotid sinus massage

32 Pharmacological treatment of hiccups Menon M, “Gabapentin in the treatment of persistent hiccups in advanced malignancy,” Indian J Palliat Care, May 2012 Calsina-Berna A et al, “Treatment of Chronic Hiccups in Cancer Patients: A Systematic Review,” Journal of Palliative Medicine, 2012
