Per UWorld Step 1, QID: 14899 (I did not directly quote since it was discouraged in the mentions):
In Streptococcus pneumo meningitis, pretreatment with dexamethasone reduces the levels of inflammatory cytokines in the CSF and limits risk of inflammation-induced morbidity (eg, seizures, focal neurologic deficits) and death.
Other forms of bacterial meningitis, such as those due to Neisseria meningitidis and Haemophilus influenzae, do not benefit from glucocorticoid pretreatment.
This is possibly due to the thinner cell walls of those organisms, resulting in less inflammatory cytokine release.
I changed c2, but I am not confident that it should be changed to what I suggested. However, the inclusion of H. flu type B instead of S. pneumo directly contradicts a question from UWorld, so it is very relevant for both step 1 and step 2 since it has step 2 tags too.
