• Recent therapy or a repeated course of therapy with beta-lactams, macrolides, or fluoroquinolones is a risk factor for pneumococcal resistance to the same class of antibiotic.

INDICATIONS FOR HOSPITALIZATION in Pneumonia —

• CURB-65 uses five prognostic variables  :

1. Confusion (based upon a specific mental test or disorientation to person, place, or time)
2. Urea (blood urea nitrogen in the United States) >7 mmol/L (20 mg/dL)
3. Respiratory rate >30 breaths/minute
4. Blood pressureChronic Long-term Complications Of Diabetes Mellitus. Read more ... » [BP] (systolic <90 mmHg or diastolic <60 mmHg)
5. Age >65 years

• The authors of the original CURB-65 report suggested that patients with a CURB-65 score of 0 to 1,
• Those with a score of 2 should be admitted to the hospital, and those with a score of 3 or more should be assessed for ICU care, particularly if the score was 4 or 5.

No comorbidities or recent antibiotic use —

• For uncomplicated pneumonia in patients who do not require hospitalization, have no significant comorbidities and/or use of antibiotics within the last three months,
• Azithromycin
  • (500 mg on day one followed by four days of 250 mg a day); 500 mg a day for three days, or 2 g single dose (microsphere formulation) are acceptable alternative regimens
• Clarithromycin
  • XL (two 500 mg tablets once daily) for five days or until afebrile for 48 to 72 hours
• Doxycycline
  • (100 mg twice a day) for seven to 10 days

Comorbidities or recent antibiotic use —

• Combination therapy with a beta-lactam effective against S. pneumoniae (high-dose amoxicillin, 1 g three times daily or amoxicillin-clavulanate 2 g twice daily
• or cefpodoxime 200 mg twice daily
• or cefuroxime 500 mg twice daily) PLUS either a macrolide (azithromycin 500 mg on day one followed by four days of 250 mg a day
• or clarithromycin 250 mg twice daily or clarithromycin XL 1000 mg once daily) or doxycycline (100 mg twice daily).
• A respiratory fluoroquinolone (gemifloxacin 320 mg daily, levofloxacin 750 mg daily, or moxifloxacin 400 mg daily) for a minimum of five days.
• Treatment should be continued for a minimum of five days.

Duration of Antibiotic treatment:

• Antibiotics are given for 10 – 14 days. Azithromycin is given for 5 days.

ASPIRATION PNEUMONIA

• Aspiration pneumonia is due to foreign objects or substances entering the lower respiratory tract.
• In the supine position the most prone areas are the posterior segments of the upper lobes and the supe­rior segments of the lower lobes.
• Common in the elderly
• Organisms responsible are Enterobacter, S. aureus, S. pneumonae, H influenzae.
• In aspiration pneumonia, gastric contents or oropha­ryngeal flora are aspirated into the lungs resulting in inflammatory response and bacterial infection.
• Aspiration is common in unconscious patients, neu­romuscular diseases.

Clinical features of Aspiration pneumonia

• Gastric acid aspiration results in chemical pneumoni­tis.
• There is dyspnoea, tachypnoea, bronchospasm, cy­anosis, diffuse opacities in lung x-ray.
• Lung abscess is a common complicationHyperglycemic Hyperosmolar State (HHS) Acute Complication Of DM. Read more ... » of aspiration pneumonia.

HOSPITAL ACQUIRED PNEUMONIA

• HAP is defined as pneumonia occurring 48 hours af­ter hospital admission by a new pathogen.
• It has a high morbidity and mortality.
• It occurs in 5 – 10% of patients admitted to medical and surgical wards.
• Incidence is highest in ICU in patients on mechanical ventilation. Patients of ventilator acquired pneumo­nia (VAP) develop the disease in 4 days of intubation.
