Interestingly, one of the major pruritic conditions treated by gabapentin and pregabalin is uremic pruritus in patients with chronic kidney disease (CKD) . Although uremic pruritus is not classically considered to be a neuropathic form of pruritus, it has been shown that 65% of patients with CKD exhibit peripheral nerve disorders, such as Gabapentin is a viable treatment for conservatively managed CKD and ESKD patients with pruritus and/or RLS, but side effects are common. Gabapentin should be used with caution although higher doses do not appear to be a factor associated with side effects. Gabapentin has been successfully used to treat cutaneous pain and pruritus in a variety of conditions. The authors describe a case of PHI successfully treated with a course of gabapentin and propose that this agent be considered for use in patients who present with PHI. Our study suggests that gabapentin is a safe and effective treatment for uremic itch. Despite advances made in treatment, uremic pruritus remains a common and distressing symptom in patients on hemodialysis (HD). Gabapentin is an effective drug in the management of neuropathic pain. Gabapentin is likely effective for uremic pruritus but adverse events are common. Starting at a low dose of 100 mg orally after hemodialysis and titrating to effect may best provide effective and safe outcomes. Although the mechanisms of pruritus and pain differ substantially in the acute phase, chronic pruritus and pain share similarities, particularly in their features of peripheral and central sensitivity enhancement, diminished inhibitory spinal cord control, as well as interactions between neural, immune, and glial elements. ciated primary skin lesion.5-7 Uremic pruritus can vary from a generalized itch to a localized itch affecting the back, face, and arms.5 Uremic pruritus intensity is associated with multiple health-related quality-of-life outcomes, such as sleep quality, mood, and social function,2,7 and is independently associated with mortality.8 Uremic Multiple studies have shown that gabapentin and pregabalin appear to be effective for several forms of pruritus, particularly uremic pruritus and that of neural origin. Consideration of the underlying pathophysiology of each chronic pruritic condition and emphasis on accuracy of diagnosis are important for selecting appropriate therapeutic agents. Gabapentin or pregabalin relieved itching in 85% of 71 consecutively treated CKD patients. Patients should be advised about side effects and the drug initiated at a low dose. Patients intolerant of gabapentin may tolerate pregabalin. This study demonstrates that gabapentin can effectively alleviate pruritus in uremic patients. In 2003, a review of over 150 original papers approved the use of gabapentin for neuropathic pain, neuritis or neuralgia of various sorts, and suggested the assessment of its role in the management of pruritus.[ 11 ] improvement in pruritus score or in proportions, but not both. UVB phototherapy was found to be the treatment of choice in moderate to severe uremic pruritus.10 Another study evaluated the effect of UV phototherapy on uremic pruritus in 56 patients with chronic kidney disease (52 on HD, 4 PD). Seven Gabapentin, phototherapy, and FDA-approved difelikefalin are promising treatment options for recalcitrant uremic pruritus. Other developing treatments are opioid mediators, neural transmission mediators, and biologics targeting IL-31. For example, in reports of DOPPS participants who had severe pruritus, 18 percent received no treatment for pruritus, and 17 percent did not even report their itch symptoms to health care staff . Over two-thirds of medical directors underestimated the prevalence of pruritus in their units [ 11,15 ]. Gabapentin, an anticonvulsant, may control pruritus with neuropathic origin. The objectives of this study were to assess the efficacy of gabapentin in reducing pruritus scores of patients with uremic pruritus and evaluate its safety among dialysis patients. Gabapentin is likely effective for uremic pruritus but adverse events are common. Starting at a low dose of 100 mg orally after hemodialysis and titrating to effect may best provide effective and safe outcomes. Gabapentin is a viable treatment for conservatively managed CKD and ESKD patients with pruritus and/or RLS, but side effects are common. Gabapentin should be used with caution although higher doses do not appear to be a factor associated with side effects. Gabapentin is a promising and a well-tolerated treatment option for patients with UP. We recommend it as a first line therapy with a maintenance post-HD dose of 100-300 mg. We also recommend the 5-D scale in the assessment of the severity of pruritus. There is a modest but growing body of literature showing the efficacy of gabapentin in the management of both uremic RLS and pruritus. There are two principal concerns when prescribing gabapentin to this cohort of patients: dose strength and frequency. Interestingly, one of the major pruritic conditions treated by gabapentin and pregabalin is uremic pruritus in patients with chronic kidney disease (CKD) . Although uremic pruritus is not classically considered to be a neuropathic form of pruritus, it has been shown that 65% of patients with CKD exhibit peripheral nerve disorders, such as A statistically significant difference was found in each domain of 5D-Pruritus scale after gabapentin and pregabalin therapy.

Skin problems are one among the many frustrating manifestations of end-stage renal disease affecting 25%–90% of patients.
