Nocturnal pruritus common among pruritic
conditions, diminishes quality of life
N
octurnal pruritus was found to be a
common complaint among a wide
range of pruritic conditions, and
exerts a negative impact on quality of life,
report results of a retrospective analysis.
Michael Lavery, MD, of Lewis Katz School
of Medicine at Temple University, Philadel-
phia, and colleagues set out to assess the
prevalence, characteristics, and impact
on quality of life of patients with noctur-
nal pruritus.
Patients who attended an “itch clinic” from
2015 to 2016 were surveyed. Patients with
chronic itch (≥6 weeks) were asked to
complete a validated questionnaire assess-
ment of pruritus.
This itch questionnaire assessed the
severity of itch on a numeric rating scale
of 0–10 and several associated character-
istics, including the presence and severity
of nocturnal pruritus and sleep disturbance
on a scale of 0–4. A validated quality of life
questionnaire (ItchyQ) was also completed.
Questionnaires from 160 subjects were
analysed. Mean subject age was 57 ± 16.
Ninety-seven (60.6%) of the cohort were
female and 63 (39.4%) were male. A total
of 146 of the 160 subjects (91.3%) reported
suffering from nocturnal pruritus.
The most common conditions that
co-occurred with nocturnal pruritus were
atopic dermatitis, prurigo nodularis,
brachioradial pruritus, and psoriasis.
Mean itch intensity severity was signifi-
cantly high (8.2 ± 2.1). Subjects reported
significantly higher itch severity at night vs
during the day (P < 0.0001). The severity
of nocturnal pruritus was significantly cor-
related with overall itch severity (r = 0.22, P
= 0.006). Of the 146 subjects with nocturnal
pruritus, 90% reported sleep disturbance.
Furthermore, for subjects with nocturnal
pruritus, the severity of itch at night corre-
lated significantly with the severity of sleep
disturbance (r = 0.35, P < 0.0001).
The severity of nocturnal pruritus corre-
lated significantly with total Itchy Quality
of Life score (r = 0.22, P = 0.006), indicating
that nocturnal pruritus was associated with
an overall reduced quality of life.
Specifically, the severity of nocturnal pruri-
tus correlated with two of the Itchy Quality
of Life subscales: functioning (r = 0.29, P =
0.0004) and emotions (r = 0.18, P = 0.03).
Dr Lavery concluded that nocturnal pruri-
tus was found to be a common complaint
among a wide range of pruritic conditions,
and exerts a negative impact on quality of
life. The results highlight the need for tar-
geted clinical interventions for patients with
chronic pruritus.
