A Case of Legionnaire’s Disease

This case report aims to provide up-to-date information about the conditions requiring hospitalization in primary health-care services in cases of Legionella pneumonia. This case was a 66-year-old female patient with a smoking history; the patient applied to emergency with increased dyspnea and fatigue. There was dyspnea and tachypnea. Inspiratory rales and bilateral widespread expiratory rhonchi were detected. C-reactive protein was 324.3 mg/L, leukocytosis was 10980 103/mm3, and neutrophil-dominated (90.2%). There was a respiratory failure (PO2: 57.3 mmHg, HCO3: 25.7 mEq/L, PCO2: 33.6 mmHg, SO2: 91.3%). Moxifloxacin (400 mg 1×1), oseltamivir (75 mg 2×1), inhaler steroid (400 mcg 2×1), and bronchodilator treatments (Salmeterol+flutikazon 50/500 mcg) were initiated empirically. However, on the 3rd day of treatment, an increase in dyspnea and orthopnea was distinguished, and parenteral ampicillin–sulbactam and methylprednisolone were added to the treatment. In the respiratory tract, bacterial polymerase chain reaction evaluation reported that Legionella was detected. Low awareness about the disease may cause serious mortality and morbidity in patients presenting with a vague clinical picture in the early stages.
