Pneumococcal pneumonia with bacteraemia.

Fourteen cases of pneumococcal pneumonia with bacteraemia have been studied. Thirteen of the patients were older than 50 years and in ten there was evidence of pre-existing disease. Pneumococci of six serotypes were responsible for these infections but type 3 was the commonest and was associated with three of the four fatal cases. The patients who died all had evidence of renal failure. Eight of the ten survivors had prerenal failure which responded to treatment. Hyponatraemia was a common finding. Despite prompt antibiotic treatment and intensive therapy there is still a high morbidity and mortality from this condition.
