WELTER, Elisângela de Quevedo et al. Relationship between pruritus and quality of life in patients on hemodialysis. An. Bras. Dermatol. [online]. 2008, vol.83, n.2, pp. 137-140. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962008000200006.
INTRODUCTION: Pruritus is a frequent symptom affecting patients on hemodialysis. Its etiology is not known and treatment is difficult. This symptom considerably worsens the patients quality of life. OBJECTIVES: To evaluate the degree of pruritus and its influence on the quality of life of patients on hemodialysis. METHODS: Patients with chronic renal disease on hemodialysis and presenting pruritus in a Hospital of Porto Alegre were enrolled in this transversal study. A visual analogue scale for measuring the degree of pruritus was used and the Dermatology Life Quality Index questionnaire was applied. RESULTS: Of 200 evaluated patients; 69 (34.5%) presented pruritus, of whom 16 (23%) of mild degree, 39 (56.5%) moderate, 14 (20.2%) severe. Quality of life assessment revealed that in 14 of the patients (20.3%) there was no influence of pruritus, in 26 (37.4%) there was a small effect, in nine (13%) a moderate effect, in 13 (18.8%) a serious effect and in seven (10.1%) there was an extremely serious influence of pruritus on the quality of life. CONCLUSIONS: In this study, 57% of the individuals did not demonstrate important alterations in the quality of life related to the pruritus. A significant number of patients on hemodialysis have their quality of life from moderately to extremely modified by pruritus, which demonstrates the need for treating this symptom.
