Consequences of CKD-aP

Look beneath the surface to the physical and mental repercussions of CKD-associated pruritus.

CKD-aP is much more than just an itch for patients that suffer with it every day.1–5 CKD-aP is an important concern for affected patients, as it impacts their quality of life, disturbs sleep and they are more likely to suffer with depression, compared with patients not bothered by itching.

Sleep quality1,2

The DOPPS study has demonstrated the association between CKD-aP and significantly reduced sleep quality, in over 20,000 patients with varying degrees of CKD-aP severity. DOPPS first demonstrated the link between CKD-aP and sleep quality in 2006 and again more recently in a 2020 publication.1,2 The 2020 publication by Sukul N, et al. adjusted their analysis to account for DOPPS phase, country, age, sex, end-stage renal disease vintage, 15 comorbidities, post-dialysis weight, albumin, haemoglobin, phosphorus, and catheter use.2

a
Patients with severe (very much and extremely bothered by itching) CKD-aP are 2–2.5 times more likely to report suffering from poor sleep quality and 2 times as likely to report feeling washed out or drained than patients not bothered by itching.2

Sleep can also play an important part of general well-being. Disrupted sleep is an important concern for patients with CKD-aP and is associated to both physical and mental quality of life outcomes.1 Patients in the DOPPS study with very severe (extremely bothered by itching) CKD-aP were 2 to 3 times more likely to have poor sleep quality, be bothered by faintness/dizziness and/or feel washed out or drained than patients not at all bothered by itchy skin.2

Social isolation

CKD-aP can make patients avoid social interactions due to the appearance of their skin and the need to scratch which causes frustration and embarrassment, contributing to social isolation.4,5

Social isolation can be a significant risk factor for poor physical health outcomes, depression and unhealthy behaviours that can further impact health (e.g. physical inactivity, poor diet and illicit drug use), regardless of age.6

Could CKD-aP be disrupting your patients’ support
network and affecting their health?

Depression

The DOPPS study has also established a link between CKD-aP and depression in both 2006 and 2020, in patients undergoing haemodialysis.1,2 In the DOPPS 2006 publication, patients with moderate to severe (moderately-extremely bothered by itching) CKD-aP were significantly more likely to be diagnosed with depression (vs. patients with mild/no CKD-aP; p≤0.004).1 In the DOPPS 2020 publication, depression was self-assessed by patients using the Centre for Epidemiologic Studies-Depression (CES-D) score derived from the 10-item ‘Boston form’.2

44% of all haemodialysis patients included in DOPPS
reported depressive symptoms.2

a
Patients extremely bothered by itching are 2 times more likely to report feeling depressed (CES-D ≥10)  than patients not bothered by itching2

Talk to your CKD patients

Ask if they’ve experienced sleep disruption, social isolation or depression due to pruritus at their next appointment or dialysis session.

The consequences of CKD-associated pruritus lie beneath the surface

CKD-associated pruritus is more likely to increase healthcare utilisation and severe CKD-associated pruritus is associated with an increased risk of mortality, compared with patients without CKD-associated pruritus.1,2,7,8 Look beneath the surface to discover the consequences of CKD-associated pruritus.
