A Survey From Major Guidelines..in the treatment of CAP & bronchitis Prepared by: Magdy El-Shafei Pharm B Group Product Manager Medical Union Pharmaceuticals M.U.P.
For the memory of a great Egyptian person in industry, Medical practice and Manhood..Prof./ Zakareya Gad Honorarium
Objective To discuss the recommendations outlined by major guidelines For Bronchitis and CAP Infectious Diseases Society of America American Thoracic Society The Canadian guidelines for the management of AECB, With a particular focus on what M.U.P. Offers for the best of our patients, Doctors and medical practice.
In AECB(ABECB) Controversial role of antibiotics • FEV1 > 50% • Exacerbations =OR> 4 /Yr. • Heart diseases • Use of Oxygen • Antibiotics in the last 3 mo.
How the antibiotics Are chosen for AECB Contribute -With M. Ctarrahlalis- to 30-50% of bronchitis 10-15% • Evidence-based practice • Best outcome for patients • Best use of resource • Least resistance • Least cost • Restricts idiosyncratic behaviour Staph. aureus Strept. Pneumonia Klebsiella Pneumonia Haemophylus influenzae >5 to 15% Mycoplasma Pneumonia Chlamydia Pneumonia Legionella Pneumophila
In Pneumonia 70% of the cases 1% Co-morbidities, Elderly 31.8 % 61.0 % Strept. Pneumonia Staph. aureus 35.7 % Mortality Klebsiella Pneumonia Haemophylus influenzae P. aeruginosa Probably the most common cause of community-acquired pneumonia 14.7 % Mycoplasma Pneumonia Chlamydia Pneumonia Legionella Pneumophila

2010 -11 Surfing across major guidelines In cases of acute exacerbations of chronic bronchitis (AECB) and community-acquired pneumonia (CAP), recent guidelines suggest: using fluoroquinolone (moxifloxacin – levofloxacin) antibiotics as first-line therapy. This suggestion is based on level I evidence from several trials (clinical and microbial superiority of these agents). Fluoroquinolones (moxifloxacin – levofloxacin) shorten hospital stay, reduce recurrences, and lower costs. Resistance is still very low. M. Balter – CFP 2002 & 2010

A study was designed to test whether cephalosporin resistance could be reversed by withdrawing these agents. The hospital-wide cephalosporin class restriction resulted in a 44% reduction in ceftazadine-resistant Klebsiella infection and colonization. COULD CEPHALOSPRINS resistance BE REVERSED??
