Each year around 80.000 people contact TBM

left with severe disability
TBM is a global problem, it is particularly
prevalent in developing world

Monotherapy with Streptomicyn reduce the case
fatality rate to 63% (Parson 1988)
Combination (Isoniazid, Rifampicin and
Pyrazinamide) fatality rate varying from 20% to
32% with permanent neurological deficit 5% to40% (Jacob, 1990; Alarcon, 1990; Ramchandran,
1986)
Doctors have used corticosteroids for TBM since
the 1950s but their role remains controversial

The corticosteroids used in different
study were :
Dexamethasone (OToole 1969, Girgis 1991,
Kumarvelu 1994, Lardizabal 1998, Thwaites
GE et al 2004)
Prednisolone (Chotmongkol 1996, Schoeman1997)

Steroids may :
Decreased inflammation, especially in
arachnoid space
Reduced cerebral and spinal cord oedema(Parson 1988, Feldman 1958)
Reduced inflammation of small blood vessels
and therefore reduce damage from blood flow
slowing to the underlying brain tissue

On the other hand, it is possible that steroids may
harm for patients :Suppress the immune response to Mycobacteria,
making the systemic effect worse
Reduced inflammation of the meningen, reducing drug
penetration into the subarachnoid space
In study reported Gastrointestinal hemorrhage (5
episodes), Glycosuria (1 episodes), infection (2
episodes) and hypothermia ( 5 episodes ) in 11 patientsreceiving dexamethasone (OToole 1969)
