Diagnose
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:
Liquor
| Normal | Virale Meningitis | Bakterielle Meningitis | Tuberkulöse Meningitis | |
|---|---|---|---|---|
| Aspekt | klar | klar | trüb | klar-trüb |
| Druck (cm H2O) | 5-12 | Normal oder (Pfeil nach oben) | >20 | Normal oder (Pfeil nach oben) |
| Leukozyten(x 106/l) | 1-4 | < 1000 Lymphozyten | > 1000
(> 70% Neutrophile) |
< 1000
(Mono- und Lymphozyten) |
| Glukose (% des Serumwertes) | 50-80% | 50-80% | < 40% | < 40% |
| Eiweiß (mg(l) | 150-500 | Normal oder (Pfeil nach oben) | >> 500 | |
| Laktat (mmol/l) | < 1,6 | < 1,6 | > 3,5 | > 1,6 |
| Direktpräparat | Negativ | Negativ | 80% positiv | 35% positiv |
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].
Xpert MTB/Rif, PCR zur Bestimmung von Tbc sowie Rifampicin-Resistenz, welches ein Hinweis für eine MDR-Tbc ist. 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% [8]
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)
