Can Pneumococcal cause injury and/or death?

disease injury death

Although most pneumococcal infections are mild, pneumococcal disease can cause serious illness.1 The 3 most common illnesses caused by invasive S. pneumoniae include pneumonia, meningitis, and bacteremia;2 however, S. pneumoniae can also cause other rare but serious pneumococcal infections including peritonitis, endocarditis and pericarditis, and infection of the bones and joints (septic arthritis, osteomyelitis).3

S. pneumoniae can also cause middle ear infections, conjunctivitis, and sinus infections but these infections are generally mild and rarely result in complications.4 5 S. pneumoniae can also cause a worsening of symptoms in someone with chronic bronchitis.6

The most common serious form of pneumococcal disease is pneumonia. Symptoms of infection may include rapid or difficulty breathing, chest pain, chills, fever, and cough. Older adults may also experience altered levels of alertness and confusion. Complications of pneumococcal pneumonia include pericarditis, airway obstruction, empyema, lung abscess, lung collapse, and death.7 Between 5 and 7 percent of persons with pneumococcal pneumonia die from the illness and elderly patients are most at risk of death.8

Since the introduction of pneumococcal conjugate vaccines, pneumococcal empyema, a complication of pneumococcal pneumonia which causes pus to accumulate between the lungs and the inner aspect of the chest wall, has become more common. 9 10  S. pneumoniae strains noted to cause this complication include serotype 1, 3, and 19A. 11 12

S. pneumoniae can also cause an infection of the blood, known as bacteremia. Initial symptoms of bacteremia may include a lower level of alertness, fever, and chills. Symptoms of sepsis, a serious complication of bacteremia, often include severe pain, sweaty or clammy skin, difficulty breathing, elevated heartrate, and confusion. Sepsis can lead to organ failure, tissue damage, and death.13

Pneumococcal meningitis, an infection of the lining of the spinal cord and brain, can also be cause by S. pneumoniae. Symptoms of infection often include sensitivity to light, headache, fever, neck stiffness, and confusion. In infants, symptoms may include a reduced level of alertness, lack of appetite, poor fluid intake, and vomiting.  Complications of pneumococcal meningitis include developmental delays, hearing loss, and death.14

Pneumococcal peritonitis, an infection of the lining of the walls of the abdomen and pelvis, is another rare but serious form of invasive pneumococcal disease. Pneumococcal peritonitis is more commonly found in persons with cirrhosis of the liver,15 HIV, and hepatitis C.16 but can also be the result of severe pelvic inflammatory disease, gastrointestinal ulcer or injury, or malignancy. Symptoms of infection often include diarrhea, vomiting, abdominal pain, fever, and dehydration.17

Pneumococcal endocarditis and pericarditis are 2 rare but serious heart infections. Symptoms of pneumococcal pericarditis often include fever, fatigue, chest pain which can radiate to the back, neck, abdomen or shoulder, cough, swelling of the extremities, and muffled heart sounds. Symptoms of pneumococcal endocarditis often include joint and/or muscle pain, fever, anorexia, sweating, and new or changing heart murmurs.18

In rare cases, S. pneumoniae can cause septic arthritis and osteomyelitis (bone infection). Symptoms of septic arthritis include hot, swollen, or painful joints and frequently involve the knees or ankles. Half of all persons who develop pneumococcal septic arthritis will also have osteomyelitis. Symptoms of osteomyelitis often include redness, warmth, and swelling to the infected area, fever, chills, pain, and children may show signs of lethargy or irritability.19

S. pneumoniae accounts for up to 50 percent of middle ear infections (otitis media). Symptoms of otitis media often include fever, a red or swollen ear drum, ear pain, and sleepiness. Ear and sinus infections are generally mild; however, children who develop frequent ear infections may require ear tube placement.20
