The role of virological monitoring A clinical perspective
MSF South Africa
Impact of routine monitoring <> Immuno-clinical monitoring on regimen change
More accurate assessment of treatment failure will reduce the delay in switching to second-line drugs. Targeted use of VL can limit unnecessary switching and routine use of VL can reduce the risk of resistance.
WHO 2010 guidelines
HIV Viral Load Monitoring in Resource-Limited Regions:
Optional or Necessary?

Predicting virological failure ( < 30 % of nadir CD4)
Sensitivity = 17.2% (12.3% - 23.0%)
Specificity = 94.5% (93.6% - 95.3%)
PPV = 18.5% (13.3% - 24.8%)
NPV = 94.0% (93.1% - 94.9%)

( Mary Ann Davies, Durban Aids conference June 2011)
VL3 group : 22% less likely to experience subsequent virological failure, 27% less likely to be later switched to second line regimen
Viral load at 3 months after initiation of antiretroviral therapy is associated with
better virological and treatment outcomes than at 6 months.

Immuno/clinical monitoring do not replace virological monitoring
Key challenges are around technical/ geographical / financial access to virological monitoring
Unitaid/ Chai/Unicef / MSF concerted efforts will work on all 3 aspects to make virological monitoring a reality in LIC by 2015
