Clinical isolates with decreased susceptibility to voriconazole have been identified.
Resistance in cell culture: relative to wild-type HBV,LVDr viruses containing rtM204V and rtL180M substitutions within the reverse transcriptase exhibit 8-fold decreased susceptibility to entecavir.
Clinical isolates with decreased susceptibility to posaconazole have been identified.
In 1 virologic failure of the PREZISTA/ritonavir group, 1 developing NRTI RAM at position 184 was identified,which was associated with a decreased susceptibility to emtricitabine included in the background regimen.
Identification of determinants of decreased susceptibility to darunavir in those viruses is under investigation.
Decreased susceptibility in Acinetobacter baumannii has been attributed to the overexpression of the AdeABC efflux pump.
In vitro, there was a clear trend toward decreased susceptibility to atazanavir as isolates exhibited high resistance levels to.
Decreased susceptibility in both groups has been attributed to the overexpression of the non-specific AcrAB multi-drug efflux pump.
An HIV isolate obtained from a patient receiving saquinavir therapy showed decreased susceptibility to saquinavir(7- fold) but did not demonstrate a concordant decrease in susceptibility to nelfinavir.
The decreased susceptibility to darunavir of the emerging viruses in the selection experiment could not be explained by the emergence of these protease mutations.
Tipranavir resistant viruses which emerge in vitro from wild-type HIV-1 show decreased susceptibility to the protease inhibitors amprenavir, atazanavir, indinavir, lopinavir, nelfinavir and ritonavir but remain sensitive to saquinavir.
Conversely, following ritonavir therapy, 6 of 7 clinical isolates with decreased ritonavir susceptibility(8- to 113-fold)in vitro compared to baseline also exhibited decreased susceptibility to nelfinavir in vitro(5- to 40 fold).
HIV-1 isolates with decreased susceptibility to amprenavir have been selected during in vitro serial passage experiments.
Isolates with baseline fold change of> 0 to 3 are considered susceptible; isolates with>3 to 10 fold changes have decreased susceptibility; isolates with> 10 fold changes are resistant.
Clinical isolates(n=5) with decreased susceptibility to zidovudine, lamivudine, or nevirapine remain fully susceptible to nelfinavir in vitro.
Of the viruses isolated from patients experiencing virologic failure by rebound from the PREZISTA/ rtv 600/ 100 mg b. i. d. group of the POWER and DUET trials,85% of those susceptible to darunavir at baseline developed decreased susceptibility to darunavir during treatment.
Viruses selected in these conditions and showing decreased susceptibility to darunavir(range: 23-50-fold) harboured 2 to 4 amino acid substitutions in the protease gene.
Caution on the choice of antibiotic agent and dose should be taken when treating patients with late-onset ventilator-associated pneumonia(> 5 days hospitalisation) andin other nosocomial pneumonia cases where pathogens with decreased susceptibility are suspected or confirmed, such as.
The combination of abacavir/lamivudine has demonstrated decreased susceptibility to viruses with the substitutions K65R with or without the M184V/I substitution, and to viruses with L74V plus the M184V/I substitution.
Tuberculosis is still one of the diseases with a major medical and social impact, and in terms of early diagnosis(which would imply a fair treatment and established at the time),difficulties related to the delay bacilli isolation in culture, decreased susceptibility testing methods to antituberculosis drugs, lack of methods for differentiation of M.
Mechanisms of resistance Strains with decreased susceptibility to daptomycin have been reported especially during the treatment of patients with difficult-to-treat infections and/ or following administration for prolonged periods.
Tipranavir maintains significant antiviral activity(< 4-fold resistance)against the majority of HIV-1 clinical isolates showing post-treatment decreased susceptibility to the currently approved protease inhibitors: amprenavir, atazanavir, indinavir, lopinavir, ritonavir, nelfinavir and saquinavir.
While it may contribute to decreased susceptibility to atazanavir when it occurs with other protease substitutions, in clinical studies N88S by itself does not lead to phenotypic resistance to atazanavir or have a consistent impact on clinical efficacy.
Overall, the in vitro characterisation of phenotypic cross-resistance between lopinavir andother protease inhibitors suggest that decreased susceptibility to lopinavir correlated closely with decreased susceptibility to ritonavir and indinavir, but did not correlate closely with decreased susceptibility to amprenavir, saquinavir, and nelfinavir.
Cross-resistance Darunavir has a< 10-fold decreased susceptibility against 90% of 3,309 clinical isolates resistant to amprenavir, atazanavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir and/or tipranavir showing that viruses resistant to most PIs remain susceptible to darunavir.
In many instances the nitrile mimics functionality present in substrates for enzymes,whereas in other cases the nitrile increases water solubility or decreases susceptibility to oxidative metabolism in the liver. The nitrile functional group is found in several drugs.
Substitutions observed in clinical isolates(rtT184A, C, F, G, I, L, M or S; rtS202 C, G or I; and/ or rtM250I, L or V)further decreased entecavir susceptibility 16- to 741-fold relative to wild-type virus.
Incorporation of additional ETVr amino acid changes rtT184,rtS202 or rtM250 decreases entecavir susceptibility in cell culture.
These signature mutations decrease viral susceptibility to raltegravir and addition of other mutations results in a further decrease in raltegravir susceptibility. .
