Enhancing pharmacology of ARVs using evidencebased probiotics
12
HIV mediated loss of Th17 cells from GALT during acute
infection4
Impairs mucosal integrity and innate defense mechanisms
Microbial translocation correlates with chronic immune
hyperactivation
Maintaining a healthy GALT may be key to reducing
pathogenic potential of HIV due to compromised flora and
subsequent barrier disruption resulting in elevation in
inflammation
Conclusion
13
Intervention with therapeutic probiotics HIV\AIDS
of drug absorption and drug resistance
diarrhea and GI side-effects and other SAEs
compliance to HAART
