Guidelines for the Use of Antibiotics in Acute Upper Respiratory Tract Infections DAVID M Guidelines for the Use of Antibiotics in Acute Upper Respiratory Tract Infections DAVID M. WONG, D.O., Arrowhead Regional Medical Center, Colton, California DEAN A. BLUMBERG, M.D., University of California at Davis Medical Center, Sacramento, California LISA G. LOWE, M.D., M.P.H., University of California at San Diego Medical Center, San Diego, California To help physicians with the appropriate use of antibiotics in children and adults with upper respiratory tract infection, a multidisciplinary team evaluated existing guidelines and summarized key practice points. Acute otitis media in children should be diagnosed only if there is abrupt onset, signs of middle ear effusion, and symptoms of inflammation. A period of observation without immediate use of anti- biotics is an option for certain children. In patients with sinus infec- tion, acute bacterial rhinosinusitis should be diagnosed and treated with antibiotics only if symptoms have not improved after 10 days or have worsened after five to seven days. In patients with sore throat, a diagnosis of group A beta-hemolytic streptococcus pharyngitis gener- ally requires confirmation with rapid antigen testing, although other lou guidelines allow for empiric therapy if a validated clinical rule suggests PE ara a high likelihood of infection. Acute bronchitis in otherwise healthy W. K N H adults should not be treated with antibiotics; delayed prescriptions O may help ease patient fears and simultaneously reduce inappropriate use of antibiotics.

SORT: KEY RECOMMENDATIONS FOR PRACTICE Evidence Clinical recommendation rating References Clinical criteria that assist in the diagnosis of acute otitis media include C 6 the abrupt onset of signs and symptoms, the presence of middle ear effusion, and signs or symptoms of middle ear inflammation. A period of observation is appropriate for select children with acute C 6 otitis media and nonsevere symptoms. A diagnosis of acute bacterial rhinosinusitis should be considered in C 7 patients with symptoms of a viral upper respiratory infection that have not improved after 10 days or that worsen after five to seven days. Treatment of sinus infection with antibiotics in the first week of C 7 symptoms is not recommended.

  • Acute Otitis Media, Acute Bacterial Sinusitis, and Acute Bacterial Rhinosinusitis
    Acute Otitis Media, Acute Bacterial Sinusitis, and Acute Bacterial Rhinosinusitis This guideline, developed by Larry Simmons, MD, in collaboration with the ANGELS team, on October 3, 2013, is a significantly revised version of the Recurrent Otitis Media guideline by Bryan Burke, MD, and includes the most recent information for acute otitis media, acute bacterial sinusitis, and acute bacterial rhinosinusitis. Last reviewed by Larry Simmons, MD on July 5, 2016. Preface As the risk factors for the development of acute otitis media (AOM) and acute bacterial sinusitis (ABS)/ acute bacterial rhinosinusitis (ABRS) are similar, the bacterial pathogens are essentially the same for both AOM and ABS/ABRS, and since the antimicrobial treatments are similar, the following guideline is based, unless otherwise referenced, on recently published evidenced-based guidelines by the American Academy of Pediatrics (AAP) for AOM,1,2 and by the Infectious Diseases Society of 3 America (IDSA) for ABRS. This guideline applies to children 6 months to 12 years of age and otherwise healthy children without pressure equalizer (PE) tubes, immune deficiencies, cochlear implants, or anatomic abnormalities including cleft palate, craniofacial anomalies, and Down syndrome. However, the IDSA ABRS guideline includes recommendations for children and adult patients. Key Points Acute otitis media (AOM) is characterized by a bulging tympanic membrane (TM) + middle-ear effusion. Antibiotic treatment is indicated in children ≥6 months of age with severe AOM, children 6-23 months of age with mild signs/symptoms of bilateral AOM. In children 6-23 months of age with non-severe unilateral AOM, and in children ≥24 months of age with bilateral or unilateral 1 AOM who have mild pain and low fever <39°C/102.2°F, either antibiotic treatment or observation is appropriate.

  • Acute (Serious) Bronchitis
    Acute (serious) Bronchitis This is an infection of the air tubes that go down to your lungs. It often follows a cold or the flu. Most people do not need treatment for this. The infection normally goes away in 7-10 days. We make every effort to make sure the information is correct (right). However, we cannot be responsible for any actions as a result of using this information. Getting Acute Bronchitis How the lungs work Your lungs are like two large sponges filled with tubes. As you breathe in, you suck oxygen through your nose and mouth into a tube in your neck. Bacteria and viruses in the air can travel into your lungs. Normally, this does not cause a problem as your body kills the bacteria, or viruses. However, sometimes infection can get through. If you smoke or if you have had another illness, infections are more likely to get through. Acute Bronchitis Acute bronchitis is when the large airways (breathing tubes) to the lungs get inflamed (swollen and sore). The infection makes the airways swell and you get a build up of phlegm (thick mucus). Coughing is a way of getting the phlegm out of your airways. The cough can sometimes last for up to 3 weeks. Acute Bronchitis usually goes away on its own and does not need treatment. We make every effort to make sure the information is correct (right). However, we cannot be responsible for any actions as a result of using this information. Symptoms (feelings that show you may have the illness) Symptoms of Acute Bronchitis include: • A chesty cough • Coughing up mucus, which is usually yellow, or green • Breathlessness when doing more energetic activities • Wheeziness • Dry mouth • High temperature • Headache • Loss of appetite The cough usually lasts between 7-10 days.

HIGGINS, DO, Envoy Hospice and Brookdale Hospice, Fort Worth, Texas EVAN D. PEREZ, MD, Memorial Family Medicine Residency, Sugar Land, Texas Group A beta-hemolytic streptococcal (GABHS) infection causes 15% to 30% of sore throats in children and 5% to 15% in adults, and is more common in the late winter and early spring. The strongest independent predictors of GABHS pharyngitis are patient age of five to 15 years, absence of cough, tender anterior cervical adenopa- thy, tonsillar exudates, and fever. To diagnose GABHS pharyngitis, a rapid antigen detection test should be ordered in patients with a modified Centor or FeverPAIN score of 2 or 3. First-line treatment for GABHS pharyngitis includes a 10-day course of penicillin or amoxicillin. Patients allergic to penicillin can be treated with first- generation cephalosporins, clindamycin, or macrolide antibiotics. Nonsteroidal anti-inflammatory drugs are more effective than acet- aminophen and placebo for treatment of fever and pain associated with GABHS pharyngitis; medicated throat lozenges used every two hours are also effective. Corticosteroids provide only a small reduc- tion in the duration of symptoms and should not be used routinely. (Am Fam Physician. 2016;94(1):24-31.

In these conditions, the administration of mucoactive agents is often indicated as adjuvant therapy. N-acetylcysteine (NAC) is a typical example of a mucolytic agent. A retrospective review of patients with pulmonary aspergillosis treated at the National Aspergillosis Centre in Manchester, United Kingdom, with NAC between November 2015 and November 2017 was carried out. Six Caucasians with Aspergillus lung disease received NAC to facilitate clearance of their viscid bronchial mucus secretions. One patient developed immediate bronchospasm on the first dose and could not be treated. Of the remainder, two (33%) derived benefit, with increased expectoration and reduced symptoms. Continued response was sustained over 6–7 months, without any apparent toxicity. In addition, a systematic review of the literature is provided to analyze the utility of NAC in the management of respiratory conditions which have unresponsive bronchial obstruction as a feature.
