BACKGROUND Even though the pathogenicity and invasiveness of pneumococcus largely depend on capsular types, the impact of serotypes on post-viral pneumococcal pneumonia is unknown. METHODS AND FINDINGS This study was performed to evaluate the impact of capsular serotypes on the development of pneumococcal pneumonia after preceding respiratory viral infections. Patients with a diagnosis of pne...
introduction acute disseminated encephalomyelitis (adem) is an acute inflammatory and demyelinating disease of the central nervous system, resulting in various neurological symptoms. usually, the disease appears following vaccination or systemic viral infections. in rare cases, the disease appears following pneumococcal infections. case presentation the patient was a 27 year-old man who was ref...
bronchiectasis is a chronic debilitating condition characterized by abnormal dilated thick-walled bronchi. to investigate humoral immune function in bronchiectatic patients, this study was performed . forty patients with established diagnosis of bronchiectasis, who were referred from two tertiary care pulmonology centers in tehran, were investigated in this study. immunoglobulin isotypes concen...
Diagnosis of invasive pneumococcal disease is challenging. We compared Binax NOW pneumococcal urinary antigen test with blood pneumococcal PCR in healthy Malawian children with and without pneumococcal carriage, and we found a high false-positive rate with Binax NOW. Blood pneumococcal PCR positivity was 66/88 (75%) compared to 5/27 (18%) when nasopharyngeal swabbing was performed first compare...
Pneumococcal pneumonia is concentrated among the elderly. Using a decision analytic model, we projected the future incidence of pneumococcal pneumonia and associated healthcare utilization and costs accounting for an aging US population. Between 2004 and 2040, as the population increases by 38%, pneumococcal pneumonia hospitalizations will increase by 96% (from 401 000 to 790 000), because popu...
BACKGROUND Several cohort studies have indicated associations between S. pneumoniae and other microbes in the nasopharynx. To study causal relationships between the nasopharyngeal microbiome and pneumococcal carriage, we employed an experimental human pneumococcal carriage model. Healthy adult volunteers were assessed for pneumococcal carriage by culture of nasal wash samples (NWS). Those witho...
A 53-year-old woman with systemic lupus erythematosus presented with a 3-day history of fever and coughing. Diagnosis of pneumococcal bronchitis was made based on symptoms and positivity of pneumococcal urinary antigen test. On day 3, severe low back pain acutely occurred. Pneumococcal vertebral osteomyelitis and psoas abscess was diagnosed 17 days later by yield of penicillin-susceptible S. pn...
This study examined the effectiveness of a community-wide outreach campaign to promote the use of pneumococcal vaccine at public flu immunization clinics, and assessed whether this intervention was more effective than simply making pneumococcal vaccination available at such clinics. In 1997, a community-wide outreach campaign promoting pneumococcal and influenza immunizations was launched in a ...
Pneumococcal polysaccharide vaccine has been licensed for use in the United States for >30 years, and two-thirds of the elderly population in the United States have received this vaccine. Observational studies have demonstrated that pneumococcal polysaccharide vaccine reduces the risk of invasive pneumococcal disease in immunocompetent elderly individuals, but neither observational studies nor ...
To evaluate the clinical outcomes of pneumococcal pneumonia caused by antibiotic-resistant strains in Asian countries, we performed a prospective observational study of 233 cases of adult pneumococcal pneumonia in 9 Asian countries from January 2000 to June 2001. Among 233 isolates, 128 (55%) were not susceptible to penicillin (25.3% were intermediately susceptible, and 29.6% were resistant). C...
