A

Two patients who experienced grade 3-4 neurotoxicity in the aSTR were under linezolid (1 from the start of treatment and 1 after switching amikacin to linezolid).

B

All 3 patients who experienced grade 3-4 anaemia in the aSTR were under linezolid from the start of treatment.

C

The 3 patients who experienced grade 3-4 hepatotoxicity in the aSTR were under linezolid from the start of treatment.

D

Others registered AE were gastritis disorders (19), skin rash/Pruritus (3), and ionic disturbances (3).

AE = adverse event; N = number; aSTR = Niger treatment strategy with a second-line injectable drug (SLID)-containing short treatment regimen (STR), with linezolid replacing the SLID in case of any grade of ototoxicity on monthly audiometry; oSTR = all oral short treatment regimen with linezolid throughout the intensive phase.
