  • Streptococcus pneumonia infection

    Streptococcus pneumonia infection also known as pneumococcal disease is an infection caused by Streptococcus pneumonia bacteria. These bacteria can affect to the different parts of the body causing different signs and symptoms depending on the site of infection. Pneumonia i.e., infection of the lungs, ear infections, sinus infections, meningitis i.e., infection of the covering around the brain, spinal cord and bacteremia covering blood stream infection. Streptococcus pneumoniae is communicable and spread from the infected person through coughing, sneezing, and close contact. The symptoms include fever, cough, shortness of breath, chest pain, stiff neck, confusion and disorientation, sensitivity to light, joint pain, chills, ear pain, sleeplessness, and irritability. In extreme cases Streptococcus pneumoniae infection can cause brain damage, hearing loss and death. Streptococcus pneumoniae infection mainly tends to occur in the elderly or in people with serious underlying medical conditions. Groups such as children under 2 years of age, children in childcare and Torres Strait Islander people. Streptococcus pneumoniae infection is usually diagnosed by microscopic examination and growth of bacteria from blood, sputum or other specimens. PCR (polymerase chain reaction) testing in a pathology laboratory is also used.

    In Canada before 2005, large outbreaks of pneumococcal disease, including invasive pneumococcal disease caused by serotype 5, were rare. Since then, an epidemic of serotype 5 invasive pneumococcal disease was reported: 52 cases during 2005, 393 during 2006, 457 during 2007, 104 during 2008, and 42 during in 2009. Of these 1,048 cases, 1,043 (99.5%) occurred in the western provinces of Canada. Median patient age was 41 years, and most (659 [59.3%]) patients were male. Most frequently representing serotype 5 cases (compared with a subset of persons with non–serotype 5 cases) were persons who were of First Nations heritage or homeless. Restriction fragment-length polymorphism typing indicated that the epidemic was caused by a single clone, which multilocus sequence typing identified as sequence type 289. Large pneumococcal epidemics might go unrecognized without surveillance programs to document fluctuations in serotype prevalence. Symptoms widely vary in patients with pneumococcal pneumonia, mild illness to febrile pneumonia to respiratory distress requiring ICU-level care. Factors such as age, type of symptoms, and duration of symptoms, underlying or chronic illness, and compliance with treatment, appropriate home care and potential for worsening disease are considered in determining the need and level of hospitalization.

    Most hospitalized should be treated with parenteral antibiotics in addition to medications for pulmonary symptoms, pain medications, intravenous fluids or parenteral or enteral nutrition, oxygen, and additional medications, as indicated on an individual basis. The use of steroids in adult patients with bacterial meningitis is recommended with caution, as they may decrease CSF antibiotic concentration; patients with meningitis treated with steroids should be monitored closely. Steroids can be considered prior to antibiotic therapy in children aged 6 weeks and older with pneumococcal meningitis. They should be given before or at the time of first dose of antibiotics. Intravenous fluids, parenteral or enteral nutrition, and other medications should be used as indicated clinical instances. A patient with pneumococcal bacteremia is treated with appropriate antibiotics. Children who undergo workup to rule out serious bacterial illness but who are not treated initially with antibiotics and whose cultures subsequently grow S pneumoniae are often asymptomatic and have negative repeat blood culture findings at follow-up. Repeat blood cultures should always be obtained in patients with S pneumoniae bacteremia. Patients with cardiac, skin or soft-tissue, bone, and joint infections with S pneumoniae should usually be admitted to the hospital for observation, intravenous antibiotic therapy, expedition of further workup and evaluation of location. Major Research is been done in Canada on Streptococcus pneumoniae infection by Public Health Agency of Canada, Centers for Disease Control and Prevention.
