Methods / characteristics of patients Cryptococcal meningitis in resource-limited countries High burden : 500 000 deaths per year in sub-Saharan Africa Amphotericin B + flucytosine + serial lombar punctures (LP) = gold standard treatment but often unavailable Treatment is usually fluconazole alone 800 to 1200 mg/day Prospective pilot study of « optimal real life treatment » for induction phase : 41 patients : oral fluconazole 1600 mg + oral flucytosine + serial LP (2 weeks) Excluded : children, relapse, comatose (Glasgow < 9)
Results : mortality rates Results of ANRS 12257 study In the litterature Study / Arm Mortality rate at 2 weeks Mortality rate at 10 weeks Mortality rate at 24 weeks Fluco 1200 (1) 55% Fluco 1200 (2) 37 % 48 % Fluco 1200 + flucytosine (2) 10 % 43 % AmB (3) 25% 44% 53% AmB + fluco 800 (3) 20% 33% 45% AmB + flucytosine (3) 15% 30% 34% Fluco 1200 + flucytosine (4) 18 % 35 % AmB-based 7 days (4) 22 % 36 % (1) Gaskell, PLoS One 2014 (2) Nussbaum, CID 2010 (Malawi) (3) Day, NEJM 2013 (Vietnam) (4) ACTA Trial, IAS 2017
Results : early fongicidal activity (EFA) EFA = -0.27 +/- 0.20 logCFU/ml/day In the litterature Study / Arm EFA (log CFU / ml / day) Fluco 1200 (1) - 0.11 Fluco 1200 + flucytosine (1) - 0.28 AmB (2) - 0.31 AmB + fluco 800 (2) - 0.32 AmB + flucytosine (2) - 0.42 Fluco 1200 + flucytosine (3) -0.26 AmB-based 7 days (3) -0.40 (1) Nussbaum, CID 2010 (Malawi) (2) Day, NEJM 2013 (Vietnam) (3) ACTA Trial, IAS 2017
Conclusion CAN WE DO BETTER ? YES WE SHOULD => Urgent need of Amphotericin B (short course 7 days) => Fluconazole –based preemptive strategies Acknowledgements : ANRS, IMEA, and every physician of the study in Côte d’Ivoire and Burundi
