Sequelae of meningococcal disease - studied about six weeks after hospital admission.

As part of a greater project (MenOPP), the type, distribution and frequency of sequelae after meningococcal disease (MCd) were estimated on the basis of examinations carried out about six weeks after hospital admission. Well documented sequelae were found in about 18% of 102 MCd cases compared to about 3% in 61 control patients. In 18 control patients with meningitis/septicemia due to other bacteria, the sequelae frequency was 11%. Our MCd sequelae results correspond with many of those published during the last few years. The frequency of uncertain sequelae was about the same (16%) in the MCd and the control group patients. A routine examination six weeks and one year after a MCd episode seems to be useful for the individual patient and for the research on better prophylaxis and improved treatment.
