non-nuke – a common term for NNRTI.

elite controller (EC) – if your viral load stays undetectable for more than five years without ART you are an elite controller.

Elite controllers also have a very good CD4 count (always above 500 cells/mm3) that stays at a similar level over many years.

Even with this good immune response, ART is still generally recommended in the long-term.

This is because over decades – some ECs have been undetectable for more than 20 years – there is a concern that low level HIV in different body compartments like the brain, might lead to accumulative serious damage that isn’t easy to detect until it is too late.

This is a real concern, though evidence is limited because of the rarity of ECs.

See: long-term slow progressor (LTSP)/long-term non-progessor (LTNP).

LTNP / LTSP – See: long-term non-progressor.

codon – the word for the junction on genetic material (DNA or RNA) occupied by three nucleotides (or bases) to form an amino acid. In HIV it is most used when refering to drug resistance. There is an amino acid at each codon and the codons are numbered (starting from 1) for each section of the HIV gene. For example the mutation M184V in RT refers to a mutation change at codon 184 in the reverse transcriptase gene.

natural history – the pattern a disease follows if it is not treated. The natural history of HIV includes very high viral load in the first weeks or months of infection (seroconversion), a drop in CD4 counts that then recovers, and then a slower progressive increase in viral load and decrease in CD4 count, that eventually lead to opportunistic infections.
