They are also seen in patients with end-stage kidney disease on hemodialysis, Hodgkins disease, pellagra, and sickle cell anaemia.The lines remain visible as long as protein intake is inadequate or synthesis is impaired, and they should disappear upon return to normal function.In extreme conditions, Muehrckes lines may also arise from physical changes in peripheral circulation: one case study reported appearance of the lines in a healthy subject following ascent to 8,848 meters (29,029 ft) on Mount Everest. History
Muehrckes lines were described by American physician Robert C. Muehrcke (1921–2003) in 1956. In a study published in BMJ, he examined patients with known chronic hypoalbuminemia and healthy volunteers, finding that the appearance of multiple transverse white lines was a highly specific marker for low serum albumin (no subject with the sign had SA over 2.2 g/dL), was associated with severity of the underlying condition, and disappeared upon successful treatment (corticosteroids in nephrotic syndrome) or direct infusion of HSA.
