Refeeding syndrome as described in 1507 by Antonio Benivieni in Florence

In 1981, Weinsier and Krumdieck described death resulting from overzealous total parenteral nutrition in two chronically malnourished, but stable, patients given aggressive total parenteral nutrition. This was the birth of what is now called the refeeding syndrome, a nutrition-related disorder associated with severe electrolyte disturbances. The purpose of this work is to demonstrate that refeeding syndrome was first described medically in Florence by Antonio Benivieni in 1507 in his book On Some Hidden and Remarkable Causes of Diseases and Cures. What we now know as refeeding syndrome was described in Report No. LVII of that book. The condition occurred as a result of the famine that affected Florence in 1496. The report documents (i) death due to starvation, (ii) death due to ingestion of deteriorated/toxic foods (inevitable in times of famine when healthy food is scarce), (iii) death caused by excessive food ingestion after forced, prolonged abstinence from food in adults, (iv) the death of breast-fed children and of their starved mothers eating to satiety and (v) the more favourable clinical outcome of those admitted to hospitals. It is possible that Benivieni was inspired by the description of the deaths of starved deserters in the book The Jewish War (70 AD) by the Romano-Jewish historian Flavius Josephus. Nevertheless, Benivieni wrote the first medical account of the central clinical features of refeeding syndrome. The main, broad clinical aspects of refeeding syndrome, described by Weinsier and Krumdieck in 1981, had been documented in medical literature four centuries earlier by Benivieni.
