Description

Nagendra and co-authors map, in 2026, the evidence for using the drug rifampicin as an antivirulence helper against hypervirulent Klebsiella pneumoniae. The germ causes invasive infections caught outside hospitals that sometimes fail treatment despite laboratory susceptibility. Lab work suggests rifampicin tamps down the bacterium's hypermucoviscous capsule through control of capsule genes. Using Joanna Briggs and PRISMA-ScR methods, they searched four databases plus grey sources to May 2026.

Of 1,361 records found, only 11 studies qualified: four experimental or mechanism papers, five clinical case reports, and two conference abstracts. Lab studies supported capsule suppression via the RpoB-rmpA pathway, and pairing with zidovudine or outer membrane disruptors looked stronger than rifampicin alone. Reported dosing ranged from 450 milligrams once daily to 600 milligrams twice daily where stated. The authors judge the effect plausible in biology but unproven in patients, casting rifampicin as a possible salvage add-on, not a proven strategy.
