Associated with a host of different diseases, pruritus is a cardinal symptom that poses an interdisciplinary diagnostic and therapeutic challenge. Over time, that symptom may progress independently of the initial cause, thus losing its function as a warning sign and turning into a clinically relevant disease of its own. In Germany, approximately 13.5 % of the general population are affected by chronic pruritus, with an incidence of 7 %. All forms of chronic pruritus require targeted treatment consisting of (a) diagnosis and management of the underlying disease, (b) dermatological treatment of primary or secondary (for example, dry skin, scratch lesions) symptoms, (c) symptomatic antipruritic treatment, and (d) psychological/psychotherapeutic treatment in case of an underlying or associated psychological or psychosomatic condition. Medical care of patients with chronic pruritus should therefore include an interdisciplinary approach, in particular with respect to diagnosis and therapy of the underlying disease as well as in terms of the management of treatment and adverse events. The objective of the present interdisciplinary guidelines is to define and standardize diagnostic and therapeutic procedures in patients with chronic pruritus. This is a short version of the current S2 guidelines on chronic pruritus. The long version may be found at www.awmf.org.

“…However, also the presentation of certain (audio-) visual stimulus material has repeatedly been shown to induce itch. By now there are several studies, which found that the presentation of itch-related stimuli, like pictures of crawling insects or videos showing other people scratching, can trigger itch and scratch responses in both healthy subjects and patients with chronic itch (Niemeier et al, 2000; Papoiu et al, 2011b; Lloyd et al, 2013; Schut et al, 2014, 2015b). However, so far there are only two studies, which investigated brain activity induced by such itch related stimuli (Holle et al, 2012; Mochizuki et al, 2013).…”

Brain Processing of Contagious Itch in Patients with Atopic Dermatitis

et al. 2017

Several studies show that itch and scratching cannot only be induced by pruritogens like histamine or cowhage, but also by the presentation of certain (audio-) visual stimuli like pictures on crawling insects or videos showing other people scratching. This phenomenon is coined “Contagious itch” (CI). Due to the fact that CI is more profound in patients with the chronic itchy skin disease atopic dermatitis (AD), we believe that it is highly relevant to study brain processing of CI in this group. Knowledge on brain areas involved in CI in AD-patients can provide us with useful hints regarding non-invasive treatments that AD-patients could profit from when they are confronted with itch-inducing situations in daily life. Therefore, this study investigated the brain processing of CI in AD-patients. 11 AD-patients underwent fMRI scans during the presentation of an itch inducing experimental video (EV) and a non-itch inducing control video (CV). Perfusion based brain activity was measured using arterial spin labeling functional MRI. As expected, the EV compared to the CV led to an increase in itch and scratching (p < 0.05). CI led to a significant increase in brain activity in the supplementary motor area, left ventral striatum and right orbitofrontal cortex (threshold: p < 0.001; cluster size k > 50). Moreover, itch induced by watching the EV was by trend correlated with activity in memory-related regions including the temporal cortex and the (pre-) cuneus as well as the posterior operculum, a brain region involved in itch processing (threshold: p < 0.005; cluster size k > 50). These findings suggest that the fronto-striatal circuit, which is associated with the desire to scratch, might be a target region for non-invasive treatments in AD patients.

“…It is important to recognize that the extent to which subjects react to itch stimuli does not only depend on the itch stimulus (e.g. Kodama et al, 1999;Verhoeven et al, 2008;Van Laarhoven et al, 2011;Schut and Kupfer, 2013;Schut et al, 2014Schut et al, , 2015b. In a study in which histamine was used to induce itch, mood was an important factor influencing the intensity of the reaction to itch stimuli (Van Laarhoven et al, 2012): Women in a positive emotional state reported less intense itch than women who had negative emotions.…”

This review focuses on personality and expectations as psychological factors related to itch induced by (audio-) visual stimuli (Holle et al, 2012;Schut et al, 2014Schut et al, , 2015b. Besides, mood, also other psychological factors like stress, itch-related cognitions, personality and expectations towards itch stimuli have been shown to be associated with itch sensations in healthy subjects and patients with itchy skin diseases (e.g.…”

“…Interestingly, the results of the studies on the associations between audiovisually induced itch and personality characteristics differed between patients with chronic itch and healthy controls (Schut et al, 2014(Schut et al, , 2015b: One study, which investigated the relationship between induced itch, scratching and personality in patients with atopic dermatitis showed that induced scratching could be predicted to a large extent, namely 53.4%, by agreeableness and public self-consciousness. AD patients, who displayed a personality that was characterized by not being very empathetic, cooperative or tender-hearted, but instead rather cruel, competitive and unfriendly (low agreeableness) and at the same time were very much concerned about what other people thought about them (high public self-consciousness) showed more induced scratch responses than patients with opposite personality characteristics (Schut et al, 2014).…”

Itch is an unpleasant, bodily sensation, which--similar to pain--evokes behavioral reactions. As a response to itch, people start scratching. There are different ways to provoke itch and subsequent scratching in experimental settings. A non-invasive method to induce itch and scratching is the presentation of itch-related (audio-) visual stimulus material, like slide-supported lectures on skin diseases or crawling insects. Also, watching videos showing other people scratching provokes itch and the desire to scratch. In this review, we focus on psychological factors, which were shown to be associated with itch and scratching provoked by (audio-) visual itch stimuli. First, we summarize the findings on the relationship between personality characteristics and (audio-) visually induced itch. Agreeableness and self-consciousness were shown to be associated with induced itch and scratching in patients with chronic skin diseases, while neuroticism was linked to induced itch in healthy subjects. Second, we present results of a recent study, in which we altered the expectations towards audio-visually induced itch and scratching by changing the information given on upcoming itch stimuli. It was shown that subjects being informed about itch stimuli in a neutral way displayed a shorter scratch duration in itch inducing situations than subjects having catastrophizing expectations. Also, the increase in scratch duration and in the number of scratch movements induced by audiovisual itch stimuli was higher when the patients were not informed about itch induction. Thus, in itch patients neither catastrophizing nor trivializing symptoms seems to be helpful.
