We report the case of a female patient with thrombocytopenic purpura W
erlhof. Splenectomy was followed by relapsing pneumococcal meningitis.
Particularly, repetitive infections were caused by pneumococcus capsu
la type 13. This type is not included in the common 23-polyvalent vacc
ine matter. The necessity of splenectomy in autoimmunological diseases
should be consired carefully in the individual case. Patients should
be well informed of the high risk of infection after splenectomy and s
hould undergo medical treatment immediately.
