Clinical Trial Summary

Toxoplasma gondii infects over one third of the global human population. Cerebral toxoplasmosis is the most common opportunistic infection in HIV patients resulting in up to 50% of mortality with proper treatment and 80% without it. The fatality mainly due to the brain edema resulted from the mass effect lesion. In addition of anti toxoplasmosis given, adjunctive therapy such as steroid is recommended in order to reduce brain edema, but the dose and duration of administration in cerebral toxoplasmosis has not been evaluated in a clinical trial. Adjunctive therapy given in cerebral toxoplasmosis patients still remains unclear. Moreover, its safety in immunodeficiency cases is still debatable.

Clinical Trial Description

Steroid produces a raising expression of anti inflammation genes (NF-κB, IκB-α and antagonist receptor IL-1) and inhibits pro inflammation cytokines ( TNF-α and IL-1β). It also works as anti edema by correcting the disrupted blood brain barrier during infection process. Dexamethasone is considered to be chosen in this clinical trial due to the long half life among steroids, the strongest glucocorticoid effect comparing other steroids, and easily prepared and used on daily practice.

There are limited data from using adjunctive steroid for treatment of HIV-associated with cerebral toxoplasmosis. Previous study in France published in 2012 showed steroid did not give any significant improvement for patients' neurological outcome and did not worsen patients' condition such as getting nosocomial infection. Meanwhile comparing previous study by Arens et. al in 2007, there was an increasing mortality rate on adjunctive steroid used in cerebral toxoplasmosis patients.

As result of limited data, our trial is looked forward to answer about the efficacy of dexamethasone treatment in reducing mortality rate of cerebral toxoplasmosis patients. ;
