Influenza A(H1N1)pdm09 Resistance and Cross-Decreased Susceptibility to Oseltamivir and Zanamivir Antiviral Drugs

Neuraminidase inhibitors (NAIs) oseltamivir and zanamivir are currently the only effective antiviral drugs available worldwide for the management of influenza. The potential development of resistance is continually threatening their use, rationalizing and highlighting the need for a close and sustained evaluation of virus susceptibility. This study aimed to analyze and characterize the phenotypic and genotypic NAIs susceptibility profiles of A(H1N1)pdm09 viruses circulating in Portugal from 2009 to 2010/2011. A total of 144 cases of A(H1N1)pdm09 virus infection from community and hospitalized patients were studied, including three suspected cases of clinical resistance to oseltamivir. Oseltamivir resistance was confirmed for two of the suspected cases. Neuraminidase (NA) H275Y resistant marker was found in viruses from both cases but for one it was only present in 26.2% of virus population, raising questions about the minimal percentage of resistant virus that should be considered relevant. Cross-decreased susceptibility to oseltamivir and zanamivir (2-4 IC50 fold-change) was detected on viruses from two potentially linked community patients from 2009. Both viruses harbored the NA I223V mutation. NA Y155H mutation was found in 18 statistical non-outlier viruses from 2009, having no impact on virus susceptibility. The mutations at NA N369K and V241I may have contributed to the significantly higher baseline IC50 value obtained to oseltamivir for 2010/2011 viruses, compared to viruses from the pandemic period. These results may contribute to a better understanding of the relationship between phenotype and genotype, which is currently challenging, and to the global assessment of A(H1N1)pdm09 virus susceptibility profile and baseline level to NAIs.

The role of spleen macrophages in malaria: an ultrastructural study

An electronmicroscopy study of the spleen from mice infected with Plasmodium berghei was carried out to investigate the types ofcells in volved in the removal of parasites from the blood, and the mechanisms by which this occurs. Macrophages, particularly from the red pulp and the marginal zone of the spleen, constituted the most important population of phagocytic cells in the spleen. At the height ofparasitaemia, macrophages in the periphery of the white pulp, especially in the mantle zone of secondary follicles, were also found to participate in phagocytosis, although to a limited extent. Our fingings suggest that phagocytosis of free parasites or parasitized erythrocytes in the spleen is an important mechanism of clearance of parasites from the circulation. Parasites removed from the erythrocytes when these cells cross the interendothelial slits are further phagocytosed by neighbouring macrophages. Evidence is presented suggesting that spleen macrophages may act against the parasite through a process of cytotoxicity.
