There is a correlation between the abnormality and the extent of the rash. A reduced glomerular filtration rate was found in a few of the patients in whom it was measured, and this must have been responsible, at least in part, for the reduced excretion of vitamin B\n                    <jats:sub>12<\/jats:sub>\n                    in these patients, but abnormal vitamin B\n                    <jats:sub>12<\/jats:sub>\n                    excretion also occurred in the absence of impaired renal function.
