Adventures in Rhinorrhea A Review of Sinusitis and Common Cold Peter Adler, MD Attending Physician UPMC Passavant 2/12/2015 Who Am I? • • • • Graduated from UPMC EM residency in 2009 Worked at Shadyside from 2009-2013 Worked in North Carolina from 2013-2014 Now work at UPMC Passavant Purpose of this talk • Explain typical course of Acute Bacterial Sinusitis (ABS) and Common Cold (CC) • Explain evidence behind our therapeutic options • Reduce your internal dread when a patient asks for an inappropriate antibiotic Patient #1 • 35 y/o male • 3 days of feeling “sick” • C/o sore throat initially – Fever yesterday to 102 – Bilateral facial pain and headache – Nonproductive cough • Rhinorrhea x 1 day, ST improving • AFVSS • Physical exam essentially WNL Should this patient receive an antibiotic? 1. Yes 2. No 50% 1 50% 2 Patient #2 • 30 y/o female with 7 days of rhinorrhea – Sore throat on days 1-3, now gone – Fever days 2-4, improved, now fever again x 1 day – No improvement in rhinorrhea • Facial pain is “getting worse” – More on left than right • Rhinorrhea is “green-colored” • Now with dental pain Should you prescribe this patient an antibiotic? (1 of 2) 1. Yes 2. No 0 of 30 50% 1 50% 2 What first-line antibiotic should you choose (assume NKDA)? (2 of 2) 1. 2. 3. 4. 5. 0 of 30 Amoxicillin Cefinidir Levofloxacin Macrodantin Linezolid 20% 1 20% 20% 2 3 20% 4 20% 5 Epidemiology of ABS/CC • ABS costs $5.8 billion/yr – Including all patients given the diagnosis of sinusitis – 11-16% of all adults will be diagnosed / yr • Common cold costs $40 billion/yr – Average kid gets 8-12x/yr – Average adult gets 2-3x/yr Ray et al. J Allergy and Clinical Immunology, Mar 1999. What % of all antibiotics prescribed in the US are for sinusitis? 1. 2. 3. 4. 0 of 30 5% 10% 20% 30% 25% 1 25% 25% 2 3 25% 4 Rhinorrhea Syndromes • Rhinitis – Involves nasal passages only • Rhinosinusitis (Sinusitis) – Involves nasal passages and sinuses • 4 sinuses – Maxillary – Sphenoid – Ethmoid – Frontal Image from http://ilmukedokterangigi.com/?p=336 dresdenplates.blogspot.com Pathogenesis of Sinusitis • Inflammatory response to bacterial/viral/ fungal/allergic challenge – Increased mucus buildup and viscosity – Ciliary paralysis or hypokinesis – Nasal conchae become obstructed and swollen – Mucus stagnates in sinuses – Further infectious contamination leads to primary or secondary infection Risk factors • Allergic rhinitis • Asthma • Nasal obstruction – Polyps – Foreign body – Nasal intubation • • • • Immunodeficiency Tobacco smoke Pollution GERD? Definitions of Sinusitis • Acute – Symptoms less than 4 weeks • Subacute – 4-8 weeks • Chronic – More than 8-12 weeks • Recurrent – 3+ episodes of acute sinusits / yr Causes of Acute Infectious Sinusitis • Viral – 98-99.5% estimated • Bacterial • Fungal – – – – – Aspergillus Candida Histoplasma Coccidioides Cryptococcus • Allergic* What’s a cold and what’s bacterial sinusitis? The $$$$$$$$$$$$$$$$ Question……………………….. http://theallergypage.com/page_18.html Time Course of URI • Time to onset 1-3 days after exposure • Total course of illness: 5-14 days – Should be improving by day 7 • Clear->yellow->green phlegm color typical • Green color of sputum DOES NOT EQUAL BACTERIA – But may be suggestive….like WBC for appendicitis Uncomplicated URI vs Sinusitis • Symptoms frequently indistinguishable from bacterial sinusitis on days 1-5!

Classical Guidelines for Diagnosis of Acute Bacterial Sinusitis • Symptoms of Viral URI for >10 days – Or acute worsening after 5-7 days • • • • Unilateral facial pain Maxillary dental pain “Moderate to Severe symptoms” “Double sickening” http://www.aafp.org/afp/2006/0915/p956.html “Official Diagnosis” of ABS • Major criteria – – – – – – Facial pain/pressure Purulent nasal discharge Fever Nasal congestion Nasal obstruction Hyposmia/anosmia • Minor criteria – – – – – – Headache Cough Fatigue Halitosis Dental pain Ear pressure *In a patient >7 days of symptoms. **2 major or 1 major and 2 minor criteria. From: Task force on rhinosinusitis: in Haro et al. Sinusitis and Rhinitis. Harwood Nuss’ Clinical Practice of Emergency Medicine, 2005 My Strategy…….. ABS if: • Days 1-5 – Fever, unilateral sinus tenderness, maxillary pain, purulent discharge (if early) • Consider delayed Abx script to start day 5-7 if trustworthy • Days 6-14ish – Abx if patient got better and then worsened – If above symptoms present and not improving • More than 2/3 weeks – Not ABS…..consider recurrent ABS or chronic Of course………… • There are some patients who you can’t convince they have a virus • Try and educate but know when to quit – Kids are exception http://www.gponlin e.com/consultationskills-staying-calmangrypatients/article/105 1676 Diagnostic tests • Imaging? – X-ray – CT – MRI • Rhinorrhea culture – Typically contaminated – Reserved for refractory sinusitis • Done by trained ENT, not us Imaging • Xrays – AP view (Caldwell) – Occipitomental 4-view (Waters) – Complete sinus opacification – Mucosal thickening >4mm – Air fluid level • CT – mucosal thickening • Ultrasound? – “back wall echo” Ghorayeb.com Imaging • X-rays – Poor specificity and sensitivity – No longer routinely used • CT – Test of choice but….. • Mucosal thickening seen in 40% of asymptomatic patients – Best test to evaluate for sinusitis complications • MRV – Test of choice to rule out Cavernous sinus thrombosis Cavernous Sinus Thrombosis http://doctorspiller.com/cavernoussinus.htm Complications • • • • • • Periorbital/orbital cellulitis/abscess Meningitis Cavernous sinus thrombosis Epidural/subdural empyema Brain abscess Maxillary sinusitis as a complication of dental abscess Chronic Sinusitis • • • • Greater than 8 weeks of symptoms Nasal steroids have shown benefit Antihistamines helpful Oral steroids also possibly beneficial but studies mixed – Seems more useful if nasal polyps present • Saline irrigation also helpful – Not well-studied in acute sinusitis Treatment of ABS/URI • Antibiotics? – Do we need them? – Which ones? – How long? • • • • • H1 antagonists? Alpha agonists? Nasal Saline? Vitamin C? Zinc? You diagnose ABS. What is the role of an antibiotic in your management? 1. None, you don’t need to give one 2. Patient will get better anyway, just faster with abx 3. The disease will spread or not improve w/o abx 33% 1 33% 2 33% 3 Are antibiotics necessary at all? • Let’s look at the data....... Abx vs Placebo at 7-15d Ahovuo-Saloranta A, Rautakorpi U-M, Borisenko OV, Liira H, Williams Jr JW, Mäkelä M. Antibiotics for acute maxillary sinusitis.

Otolaryngology-Head and Neck Surgery. 137, S1-S31. 2007. Conclusions: Abx for ABS • Antibiotics seem to decrease time to cure – Avg. 12 days with placebo – Avg. 8 days with antibioitic – No change at 2 weeks • No change in complication rates in immunocompetent patients • Adverse side effects (RR=1.75, ARR=0.11) – Diarrhea – GI upset – Allergic reaction Ahovuo-Saloranta A, Rautakorpi U-M, Borisenko OV, Liira H, Williams Jr JW, Mäkelä M.

A Comment about Dextromethorphan and Guaifenesin • Most trials on these are industry sponsored • CR: No clear evidence one way or another • UTD: Common cough medicine ingredients include guaifenesin and dextromethorphan; these are often combined with other medications in over-the-counter cold formulas. However, the benefit of cough medicines is likely to be small to non-existent. In clinical trials, cough suppressants were no more effective in reducing the duration or severity of coughing due to cold than a placebo (a non-drug substitute). • Translation: they may work but have not been proven Sexton et al.

Things that MAY work in kids • Saline irrigation/nasal spray – No good studies on therapeutics • NSAIDs – For pain and fever • Ipratropium bromide IN – Not well studied in kids, beneficial in adults • Zinc – 14% severity improvement in kids vs 8% improvement in adults if taken within 24 hours • Honey – 1-2tsp qhs for 3-5 days • Vapor Rub – one application What I would have said before this talk (adults and kids) • • • • Suck it up Drink plenty of fluids Nasal saline PRN 7-10 days to get better – 10-14 days for bronchitis • OTC meds don’t work What I will offer now (adults) • Antibiotic for ABS only if diagnosis highly suggestive • If you feel the need to give something for CC – Antihistamine/decongestant combo if not contraindicated • Or Afrin IN for 3 days – NSAIDs for pain or fever • If you feel the need to do more – Ipratropium bromide IN for rhinorrhea – Nasal Saline – Zinc lozenge if for 5 days if sx <24hours What I will offer now (kids>4) • ABS is rare, abx only if highly suggestive • If you feel the need to do something for CC – NSAIDs for pain/fever – Buckwheat honey (2 tsp qhs) – Saline nasal spray • If you feel the need to do more – Ipratropium bromide IN for rhonorrhea – Zinc lozenges for 5 days (if presenting within 24 hours) What I will offer now (kids<4) • • • • ABS basically nonexistent Bulb suctioning +/- nasal saline NSAIDs for fever If you feel the need to do something: – Honey (if age>1) • If you feel the need to do more: – No recommendations Overall conclusions • 98-99.5% of acute infectious rhinorrhea is viral • A common cold getting worse after day 5 may be acute bacterial sinusitis • Be specific with use and choice of antibiotic – Patient may be better 4 days faster with correct abx if correct diagnosis of bacterial sinusitis made • Consider use of adjunctive therapy – Especially antihistamine-decongestant combos References • Ray NF et al.
