superinfection – another term for reinfection.
Compassionate use programmes enable people with life-threatening, long-lasting or seriously disabling illnesses to use drugs that have not yet been authorised. This is usually only for drugs that are near to drug approval, especially for people who would be excluded from research studies.
This is similar to, and sometimes called, a named-patient programme.

long-term non-progressor (LTNP) – An HIV positive person whose CD4 count stays above 500 copies/mm3 with very low viral load for more than five years, without using ART.
Some LTNPs have kept their CD4 count above 500 for more than 10-15 years without ART. Recent guidelines suggest the LTNPs should still strongly consider using ART. This is because ongoing HIV replication is still likely to increase the risk of serious illnesses, even at low viral load levels,
Because CD4 counts gradually fall in LTNPs, just very slowly, a more accurate term is long-term slow-progressors (LTSPs).
Elite controllers (ECs) are a sub-group of LTSP who also maintain undetectable viral load (less than 50 copies/mL) without ART. See: elite controller.
