Amantadine may be lifesaving in severe influenza A.
at the B. P. Koirala Institute of Health Sciences (Dharan, Nepal), a policy was instituted of performing baseline and weekly electrocardiograms (ECGs) for all patients receiving sodium stibogluconate, with temporary suspension of treatment if the corrected QT interval (QTc) exceeded 0.5 s. In the several months that followed the institution of this policy, there were no sudden deaths of patient...
متن کاملAmantadine-Resistant among Seasonal H1N1 and 2009 Pandemic Isolated of Influenza A Viruses in Iran
Background and Aims: Influenza A viruses are important pathogens for humans especially in pandemic episodes. Two adamantane derivates, amantadine and rimantadine, are used for prophylaxis and treatment of influenza A virus infections. However, single amino acid substitutions in the M2 transmembrane domain which lead to amantadine resistance of these viruses occur at residues 26, 27, 30, 31 or 3...
متن کاملOseltamivir- and Amantadine-Resistant Influenza Virus A (H1N1)
To the Editor: We previously reported detection of double resistance to oseltamivir and amantadine of influenza virus A (H1N1) in Hong Kong during the first half of 2008 (1). Three different strains of A/Hong Kong/2652/2006-like (clade 2C) viruses that carried the S31N mutation in the matrix (M2) gene associated with amantadine resistance acquired a neuraminidase (NA) gene with CAT→TAT change a...
متن کاملOseltamivir- and Amantadine-Resistant Influenza Viruses A (H1N1)
Surveillance of amantadine and oseltamivir resistance among influenza viruses was begun in Hong Kong in 2006. In 2008, while both A/Brisbane/59/2007-like and A/Hong Kong/2652/2006-like viruses (H1N1) were cocirculating, we detected amantadine and oseltamivir resistance among A/Hong Kong/2652/2006-like viruses (H1N1), caused by genetic reassortment or spontaneous mutation.
متن کاملHigh frequency of amantadine-resistant influenza A (H3N2) viruses in the 2005-2006 season and rapid detection of amantadine-resistant influenza A (H3N2) viruses by MAMA-PCR.
Using the newly designed mismatch amplification mutation assay (MAMA) PCR, we demonstrated the high frequency of amantadine-resistant influenza A (H3N2) viruses isolated during the 2005-2006 season by detecting the mutation at amino acid position 31 of the M2 protein (S31N). Further, phylogenetic analyses of the HA1 sequences of the S31N viruses revealed that they comprised a clonal lineage tha...
