Inflammation and pruritus in haemodialysis patients

Background. Pruritus is a common symptom among patients on haemodialysis (HD). We studied 68 HD patients to assess the role of iron deficiency, anaemia, inflammation and other common serum and dialysis parameters in pruritus. Methods. The patients were questioned about the occurrence of pruritus at...

Zusammenfassung:Background. Pruritus is a common symptom among patients on haemodialysis (HD). We studied 68 HD patients to assess the role of iron deficiency, anaemia, inflammation and other common serum and dialysis parameters in pruritus. Methods. The patients were questioned about the occurrence of pruritus at home, quantified according to frequency (‘never’, ‘occasionally’ and ‘every day’) and intensity (‘absent’, ‘moderate’ and ‘severe’). The blood and serum variables considered were: haemoglobin, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, hypochromic red blood cells (RBC), hyperchromic RBC, microcytic RBC, macrocytic RBC, reticulocytes, iron, ferritin, transferrin, transferrin saturation, C‐reactive protein (CRP), urea, creatinine, calcium, phosphorus, albumin, total protein and glucose. We also analysed Kt/V, age and time on HD treatment. Patients were divided into 3 groups according to the frequency or intensity of their pruritus, and we analysed and compared the variables between the 3 groups. Results. Half (50%) of the patients reported never having pruritus, 32.4% occasionally and 17.6% every day. Pruritus was moderate in 41.2% of them and severe in 8.8%. None of the parameters considered revealed any statistically relevant differences between the three pruritus frequency groups, except for mean serum transferrin level (mg/dl) (‘never’=268±64 vs ‘occasionally’=244±40 vs ‘every day’=217±56, P
