  • Title: [Chemotaxis defect and recurrent E. coli meningitis].
    Author: Herpertz B, Burdach SE, Rister M.
    Journal: Monatsschr Kinderheilkd; 1985 Feb; 133(2):82-5. PubMed ID: 3885013.
    Abstract:
    The increased susceptibility to bacterial infections due to a decreased chemotaxis of neutrophil granulocytes was investigated in a premature small for gestational age baby, who such suffered from recurrent E. coli-meningitis. Causes as anatomic lesions, brain abscess, septic granuloumatosus disease and the Chédiak-Higashi-anomaly were ruled out. At the age of 9 and 13 weeks chemotaxis function compared to age-matched and adult controls was diminished. Addition of serum from healthy adults increased directed migration without reaching normal levels. The study of the complement status revealed a diminution of CH50, the alternate pathway components and C6-C9. Thus, decreased chemotaxis is believed to originate from a combined intrinsic-extrinsic defect. No relapses of infection were observed during prophylactic treatment with ascorbate and cotrimoxazole. Intrinsic as well as extrinsic chemotaxis became normal at the age of 7 months. Simultaneously, complement status was found to approach normal levels. The relevance of haematologic-immunologic evaluation in cases of relapsing severe bacterial infections in preterm newborns is discussed.
