Is increased arterial pressure predictive of haemodynamic instability in patients undergoing adrenalectomy for phaeochromocytoma?
As previously demonstrated, in patients undergoing phaeochromocytoma removal, perioperative haemodynamic changes are mainly due to catecholamine release during tumour manipulation, and to the decrease in catecholamine level following tumour removal. Whether pre-operative hypotensive drugs are likely to alter these changes remains questionable.
HIV-1 coinfection is associated with a decreased HBV-specific CD8 T-cell response that can be partially rescued in vitro by addition of IL-21.
