Pruritus is a bothersome and prevalent symptom reported by patients suffering from both cutaneous and extracutaneous diseases. Psychogenic pruritus, also referred to as functional itch disorder, is a distinct clinical entity. According to the definition proposed by the French Psychodermatology Group (FPDG) in 2007, the disorder is characterized by pruritus which is the chief complaint and psychologic factors that contribute to eliciting, worsening, and sustaining the symptoms. Specific diagnostic criteria were proposed, including 3 compulsory and 7 optional, of which 3 have to be met in order to establish the diagnosis. Psychogenic pruritus may require cooperation between dermatologists, psychiatrists, and psychologists. Psychotherapy and psychopharmacotherapy are mainstays of managing the disease. However, publications regarding psychogenic itch management are uncommon. Initially, general measures have to be taken, including avoiding irritating factors, preventing skin dryness, and frequent application of emollients. As in pruritus of other causes, several drugs are used, with more emphasis on substances that influence central nervous system: H1-antihistamines (hydroxyzine, chlorpheniramine, cyproheptadine, diphenhydramine, promethazine), tricyclic antidepressants (doxepin), tetracyclic antidepressants (mirtazapine), selective serotonin reuptake inhibitors (citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline), antipsychotic drugs (pimozide), anticonvulsants (topiramate), and benzodiazepines (alprazolam), preferably depending on the coexisting symptoms.

Neurologic itch is defined as pruritus resulting from any dysfunction of the nervous system. Itch arising due to a neuroanatomic pathology is seen to be neuropathic. Causes of neuropathic itch range from localized entrapment of a peripheral nerve to generalized degeneration of small nerve fibers. Antipruritic medications commonly used for other types of itch such as antihistamines and corticosteroids lack efficacy in neuropathic itch. Currently there are no therapeutic options that offer relief in all types of neuropathic pruritus, and treatment strategies vary according to etiology. It is best to decide on the appropriate tests and procedures in collaboration with a neurologist during the initial work-up. Treatment of neuropathic itch includes general antipruritic measures, local or systemic pharmacotherapy, various physical modalities, and surgery. Surgical intervention is the obvious choice of therapy in cases of spinal or cerebral mass, abscess, or hemorrhagic stroke, and may provide decompression in entrapment neuropathies. Symptomatic treatment is needed in the vast majority of patients. General antipruritic measures should be encouraged. Local treatment agents with at least some antipruritic effect include capsaicin, local anesthetics, doxepin, tacrolimus, and botulinum toxin A. Current systemic therapy relies on anticonvulsants such as gabapentin and pregabalin. Phototherapy, transcutaneous electrical nerve stimulation, and physical therapy have also been of value in selected cases. Among the avenues to be explored are transcranial magnetic stimulation of the brain, new topical cannabinoid receptor agonists, various modes of acupuncture, a holistic approach with healing touch, and cell transplantation to the spinal cord.

Psoriasis is a common chronic inflammatory skin disease observed in about 1-3% of the general population. About 60-90% of patients with psoriasis suffer from itching. Interestingly, in the past itch was not considered as an important symptom of psoriasis. Despite the high frequency of itch in psoriasis, the pathogenesis of this symptom is still not fully elucidated. Although most studies indicate neurogenic inflammation and the role of neuropeptides, other mediators may be important as well. The majority of psoriatic patients consider itch as the most bothersome symptom of the disease as it significantly alters daily functioning and psychosocial well-being. Patients with itch showed greater impairment of their health-related quality of life compared to those without itch, and the intensity of itch correlated with the degree of quality-of-life reduction. However, treatment options for itch in psoriasis are limited. Therapy of itch in patients with psoriasis should be directed toward the resolution of skin lesions, as disease remission usually is linked with itch relief. Recent studies have clearly pointed to an important role of apremilast and biologic agents in itch intensity reduction in subjects suffering from psoriasis. Other treatment modalities include antihistamines, especially with a sedative effect, narrowband ultraviolet B, and antidepressants (doxepin, mirtazapine, paroxetine). Support by family members and/or health professionals may also be of importance in helping psoriatic subjects cope with itch.

Introduction Pruritus is one of the frustrating skin manifestations of advanced renal failure. Many options have been used for the management of uremic pruritus (UP) such as pregabalin. There are some studies that reported beneficial effects of pregabalin in reducing UP; however, most of them did not have a comparator arm. Therefore, we designed this study to compare antipruritic effects of pregabalin with doxepin in the management of pruritus in hemodialysis patients. Methods Seventy-two patients suffering from UP were randomly assigned to receive pregabalin (50 mg every other day) or doxepin (10 mg per day) for 4 weeks. Severity of pruritus and its effect on quality of life were assessed by visual analog scale (VAS), 5-D itch scale and dermatology life quality index (DLQI) at baseline and after 1 week, 2 weeks and 4 weeks of the treatment. Findings Mean scores of the VAS decreased from 7.5± 1.4 and 7.1 ± 1.3 at baseline to 2.1 ± 2.6 and 4.2 ± 2.6 at the end of the study (P < 0.001) in the pregabalin and doxepin groups, respectively. Similarly, pregabalin significantly reduced mean scores of the 5-D itch scale and the DLQI compared to doxepin. The most reported side effect in each group was somnolence which occurred in similar rates in the both groups. Discussion Pregabalin was more effective than doxepin in reducing the severity of uremic pruritus and improving the quality of life of patients in this study, so we suggest that clinician can consider pregabalin prior to using antihistamine drugs in the management of severe itch in hemodialysis patients.

Psoriasis is a common chronic inflammatory disease with an incidence of about 0.5-3 %. Previously psoriasis was not primarily regarded to be associated with pruritus; however, this perception has changed in recent years. Meanwhile data conclusively show that between 64 and 97 % of patients report about pruritus that can be severe in a number of cases. Apart from suffering from psoriasis, the presence of pruritus causes additional stress and leads to a significant impairment of health-related quality of life. Neurogenic inflammation at least in part contributes to the development of pruritus in psoriasis skin lesions. A number of neuropeptides including substance P and calcitonin gene related peptide can act as pro-inflammatory mediators. There is evidence for a dysbalance between κ‑ and µ‑opioid receptors in lesional skin favoring inflammation and pruritus. After clearing of psoriasis lesions, pruritus is relieved as well. Therefore, specific treatment of pruritus is not necessary in general. In cases where severe pruritus is a prominent symptom, targeted therapy with mirtazapin or doxepin or neuroleptic compounds such as pregabalin or gabapentin or drugs affecting the κ‑ und µ‑opioid receptor balance can be administered. Today the importance of pruritus as a prominent symptom of psoriasis lesions has been widely accepted. In recent and running clinical trials with new drugs, pruritus at baseline and the effect of these drugs on pruritus is always assessed. This awareness also fuels basic research about pruritus in psoriasis.

Depressive symptoms are very frequent over a lifetime, especially for women. Menopause is a period of higher depressive vulnerability. There are suggestive data that estrogen deficiency may increase the susceptibility for depression. We studied whether a bilateral ovariectomy (OVX) modifies mice behaviors and antidepressant drug effects through tail suspension test (TST). We evaluated behavioral changes at 1 week, 2 weeks, and up to 2 months after OVX. The behavior responses to doxepin, paroxetine, and venlafaxine at 1 week, 2 weeks, and 2 months after OVX were evaluated. No obvious difference was detected on the duration of immobility among control group, sham group, and OVX group in the TST at 1 week and 2 weeks after OVX. But the duration of immobility of OVX group was distinctly longer than that of both control group and sham operation group at 2 months after OVX. At 1 and 2 weeks after OVX, only the antidepressant response to venlafaxine was observed, while response to paroxetine increased 2 months after OVX. Response to antidepressant drugs was strongly modified in OVX mice. The present results suggest that not all antidepressant drugs are appropriate for depression with estrogen deficiency.

Tricyclic antidepressants (TCAs) are found to have an analgesic action for relieving cutaneous pain associated with neuropathies. The aim of this study was to assess cutaneous absorption and analgesia of topically applied TCAs. Percutaneous delivery was investigated using nude mouse and pig skin models at both infinite and saturated doses. We evaluated the cutaneous analgesia in nude mice using the pinprick scores. Among five antidepressants tested in the in vitro experiment, mesoridazine, promazine and doxepin showed a superior total absorption percentage. The drug with the lowest total absorption percentage was found to be fluphenazine (<7%) either at an infinite dose or at saturated solubility. The follicular pathway was important for mesoridazine and promazine delivery. Mesoridazine showed stronger skin analgesia than the other TCAs although the in vivo skin absorption of mesoridazine (0.34nmol/mg) was less than that of promazine (0.80nmol/mg) and doxepin (0.74nmol/mg). Mesoridazine had a prolonged duration of pain relief (165min) compared to promazine (83min) and doxepin (17min). The skin irritation test demonstrated an evident barrier function deterioration and cutaneous erythema by promazine and doxepin treatment, whereas mesoridazine caused no obvious adverse effect by topical application for up to 7days.
