| Abstrakt: | Objective: To determine the prevalence of complement system deficiencies in patients who have survived a Neisseria meningitidis infection. Design: Retrospective. Setting: Reference laboratory for bacterial meningitis of the University of Amsterdam and the National Institute of Public Health and Environmental Protection. Method: Out of the files of the laboratory 187 patients who had experienced a meningococcal infection in the Netherlands between 1959-1990 were selected in two groups according to the infecting bacterial strain: 97 patients with a serogroup X, Y, Z, W135, 29E, or non-groupable strains and 90 patients with an infection due to serogroup A or C. The patients were asked for their cooperation by their family doctor and one of us visited the patients at home to take blood samples. The complement activity was studied with a haemolysis in gel test and with an assay of haemolytic activity in free solution. Results: Complement deficiency was present in 18% of the 187 patients who had experienced a meningococcal infection. The highest prevalence was found in patients older than 10 years who had developed infections due to serogroups X, Y, W135, or non-groupable strains (45%). Of the patients with a serogroup A or C infection, 3% had an complement deficiency. Of the complement deficiencies, 42% concerned a component of the alternative pathway, 12% a deficiency of C3, and 46% a component of the terminal route. The most commonly found deficiencies were properdin deficiency (39%) and C8 deficiency (18%). 30% of the complement deficient patients reported other family members having experienced meningitis. Recurrent meningitis was only observed in patients with terminal route deficiencies. Conclusion: We recommend that patients with a meningococcal infection due to serogroups X, Y, W135 or non-groupable strains should be screened for complement deficiency. |
