title: New thoughts concerning the epidemic of rickets: was the role of alum overlooked?
abstract: Recent emphasis on the re-emergence of nutritional rickets has renewed interest in the etiology and therapy of this devastating disorder. At its peak in the 19th and 20th century, rickets was a major area of study for countless experts in childhood disorders and numerous theories abounded as to its cause. These included, among others, infections, confinement or intestinal disturbances, and were largely discarded after the discovery of the role of vitamin D and the importance of ultraviolet irradiation. Once a good explanation had been found for the cause of the disorder and the curative power of vitamin D proven, whether it was obtained from the diet or through exposure to sunlight, there was no apparent need to look any further into the etiology of rickets. But in fact there may have been other contributory factors, recognition of which might have lessened the severity of the disease or hastened recovery. One of these theories might be of particular interest to pediatric nephrologists because it relates to insoluble aluminum-based phosphate binders. Namely, alum used as an adulterant in bread in certain locations may have contributed to metabolic bone disease during the great epidemic of rickets.
