BACKGROUND: Nephrogenic pruritus (NP) is a well-known associated symptom in patients with chronic renal failure. The aim of the present study was to make a detailed dermatological analysis including distribution of excoriations and their correlation with pruritus characteristics.
PATIENTS AND METHODS: Data on a total of 17 patients with NP (14 males, mean 65.4 ± SD 14.3 years) were subjected to retrospective analysis. Most of the patients developed NP after start of kidney disease; however, in 20 % of the patients, there was premonitory appearance of the symptom 18 months (median) earlier. A majority of patients reported neuropathic symptom qualities (burning, stinging). In 94.1 % of patients xerosis was present; in 58.8 %, prurigo nodularis. The latter group of patients had a longer duration of pruritus as well as up to 10 years longer duration of renal disease than those without prurigo.
RESULTS: Pruritus characteristics of NP show a wide variance without a clear profile that is useful for clinical diagnosis. NP can occur premonitorily, and, if of long duration and with coexistent metabolic diseases, can develop into prurigo.
