[A Case of Pneumococcal Pneumonia Early Diagnosed by Detection Kit RAPIRUN® in a Dialysis Patient].

Abstract A 65-year-old woman developed fever and dyspnea and visited the emergency department of our hospital. On arrival she was hypoxic, and chest CT showed bilateral centrilobular nodules, infiltrative shadows and bronchial wall thickening. Gram staining wasn't performed on admission, and the urinary antigen-detection test for Streptococcus pneumoniae couldn't be performed because the patient has suffered from anuria caused by renal failure. Therefore, we conducted S. pneumoniae antigen test (RAPIRUN® Streptococcus pneumoniae) using sputum sample, then rapidly diagnosed pneumococcal pneumonia due to the positive result of the rapid test. RAPIRUN® Streptococcus pneumoniae is considered to be useful in the differential diagnosis of pneumonia, especially for patients who are unable to urinate or on the facilities that Gram stain cannot be carried out timely.
