Diseases of the immune system (Immunology)

In our outpatient clinic we treat children with suspected congenital disorders of the immune system. This includes diseases characterized by a weakness of the immune system (immune deficiency), but also diseases with defective regulation of the immune system and unclear, recurring fever states (auto-inflammation). With our experienced team we run one of the largest immune deficiency outpatient clinics in Germany. We have special diagnostics that are only available at  few centers in Germany. We are a JMF center, Find-ID certified and listed by the Association for Pediatric Immunology (API) as a so-called CID center. As such, we perform the immediately required diagnostics in case of abnormal SCID screening (for further information please click here). Due to the cooperation with our colleagues in pediatric oncology we can offer all the necessary treatment forms for immune deficiencies.
