Anamnese

  • Chronischer Husten? Gewichtsverlust? B-Symptomatik?
  • Reiseanamnese
  • Herkunftsland
  • Frühere Tbc-Diagnose oder Therapie, Tbc-Fall im sozialen Umfeld?
  • Risikofaktoren:
    • Malnutrition
    • Immunsuppression
    • Andere Infektionen, v.a. HIV (Bei Erstdiagnose Tbc immer HIV Test)
    • Chronischer Alkoholabusus
Radiologie:
  • Röntgen-Thorax
  • Sensitivität MRT > CT für pathogene Tbc-Assoziation
  • Ggf. SPECT, PET
Mikrobiologie:

Goldstandard: Kultur auf Tbc (sensitiver als Mikroskopie, ist in bis zu 50-70% positiv). Dauer der Kultur bis 8 (-12) Wochen [1][2][3][4][5][6][7].

Es sollte eine kulturelle Resistenzbestimmung für die Medikamente der Standardtherapie erfolgen sowie zusätzlich eine molekularbiologische Analyse hinsichtlich der Genabschnitte mit einer Isoniazid- und Rifampicinresistenz. Die Verlässlichkeit eines resistenten Ergebnisses (positiv prädiktiver Wert) ist abhängig von der Häufigkeit der Resistenz in der untersuchten Bevölkerung. Liegt die MDR-Rate, wie in Deutschland, unter 5%, sinkt der positiv prädiktive Wert auf unter 70% [1]

Differentialdiagnose

  • Andere bakterielle Meningitiden (Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, Streptococcus, agalactiae), Neuroborreliose
  • Pilze: Candida spp., Aspergillus spp., Kryptokokkus spp.
  • Parasiten: Echinokokkus spp., Toxoplasma
  • Nicht-infektiös: Sarkoidose, tumorös (Meningiosis carcinomatosa)
