Inter-relationships between renal metabolism (both in physiology and renal dysfunction) and the liver.
Recently, evaluation of organ-specific glucose release showed that renal glucose release is of the same order of magnitude as splanchnic glucose release during the postabsorptive period. Moreover, renal glucose release appeared to be more sensitive to hormone action than did hepatic glucose release, and appeared to have a pre-eminent role during the adaptation to various physiological and pathological conditions. The kidney is now recognized as playing a key role in interorgan glucose metabolism, and particularly in the Cori cycle and glutamine-glucose cycle. During chronic renal failure the suppression of renal glucose release, together with impaired hormone action, decreased glycogen storage and abnormal liver gluconeogenesis, are responsible for an increased risk for hypoglycaemia.
