Systematic literature review. To review the evidence from high-quality studies regarding the treatment of neuropathic pain originating specifically from spinal disorders. In general, treatment guidelines for neuropathic pain cover all its various causes, including medical disease, peripheral neuropathy, and cancer. However, the natural history of neuropathic pain originating from spinal disorders may differ from that of the pain originating from other causes or lesions. An expert research librarian used terms related to neuropathic pain and spinal disorders, disc herniation, stenosis, and spinal cord injury to search in MEDLINE, Embase, and Cochrane CENTRAL for primary research from January 2000 to October 2015...

Cisplatin is an effective chemotherapeutic agent indicated in cancer chemotherapy. However, its clinical use is associated with peripheral neuropathy that invariably impairs patient quality of life. Gabapentin (GBP) is an effective analgesic for neuropathic pain conditions but its clinical efficacy in cisplatin-induced neuropathic pain (CINP) is limited, in addition to generating unwanted side-effects. In this study, a gabapentin-salicylaldehyde derivative [gabapentsal (GPS)] was synthesized and evaluated to explore any potential benefit in comparison with GBP in a rat model of CIPN...

INTRODUCTION: Management of patients with cancer suffering from neuropathic pain refractory to opioids and gabapentinoids remains an important challenge. Duloxetine is one of the choices after first-line treatment fails. The efficacy of duloxetine has been reported in patients with non-cancer disease and in chemotherapy-induced peripheral neuropathy, but no randomised clinical trials have examined its effects on neuropathic cancer pain refractory to first-line treatment. The objective of this study is to assess the analgesic efficacy of duloxetine in patients suffering from neuropathic cancer pain refractory to opioids and gabapentinoids...

Diabetic peripheral neuropathy (DPN) is the most common complication of diabetes mellitus (DM). More than 90% of all cases of DM belong to type 2 diabetes mellitus (T2DM). Emodin is the main active component of Radix et rhizoma rhei and has anti-bacterial, anti-viral, anti-ulcerogenic, anti-inflammatory, and anti-cancer effects. Nanoparticle encapsulation of drugs is beneficial for drug targeting and bioavailability as well as for lowering drug toxicity side effects. The aim of this study was to investigate the effects of nanoparticle-encapsulated emodin (nano emodin) on diabetic neuropathic pain (DNP) mediated by the Purin 2X3 (P2X3) receptor in the dorsal root ganglia (DRG)...

Neuropathic pain is an integral component of several chronic pain conditions and poses a major health problem worldwide. Despite emerging understanding of mechanisms behind neuropathic pain, the available treatment options are still limited in efficacy or associated with side effects, therefore making it necessary to find viable alternatives. In a genetic screen, we recently identified SerpinA3N, a serine protease inhibitor secreted in response to nerve damage by the DRG neurons and we showed that SerpinA3N acts against induction of neuropathic pain by inhibiting the T-cell- and neutrophil-derived protease, leucocyte elastase (LE)...

Chemotherapy-induced neuropathic pain is a debilitating and common side effect of cancer treatment. Mitochondrial dysfunction associated with oxidative stress in peripheral nerves has been implicated in the underlying mechanism. We investigated the potential of melatonin, a potent antioxidant that preferentially acts within mitochondria, to reduce mitochondrial damage and neuropathic pain resulting from the chemotherapeutic drug paclitaxel. In vitro, paclitaxel caused a 50% reduction of mitochondrial membrane potential and metabolic rate, independent of concentration (20-100μM)...

CONTEXT: Neuropathic pain can be present in patients developing chemotherapy-induced peripheral neuropathy (CIPN). Nerve growth factor (NGF) is trophic to small sensory fibers and regulates nociception. OBJECTIVES: We investigated the changes in serum NGF and intraepidermal nerve fiber density (IENFD) in skin biopsies of cancer patients receiving neurotoxic chemotherapy in a single-center prospective observational study. METHODS: Patients were evaluated before and after chemotherapy administration...

BACKGROUND: In an evaluation of chemotherapy-induced peripheral neuropathy (CIPN), objectivity may be poor because the evaluation is determined by the patient's subjective assessment. In such cases, management of neuropathy may be delayed and CIPN symptoms may become severe. In this pilot study, we attempted an objective evaluation of CIPN using a quantitative pain measurement system (Pain Vision(®)). METHODS: The subjects were patients with gynecologic cancer who underwent chemotherapy using taxane and platinum drugs...

BACKGROUND: For the treatment of patients with cancer to be successful and well-tolerated, the complications and side effects of the disease and its treatment must be treated and limited as far as possible. Summarized recommendations based on the constantly increasing evidence in the area of supportive care must be defined, standardized, and communicated. METHODS: We systematically reviewed the literature on the topics of anemia, neutropenia, nausea/vomiting, diarrhea, oral mucositis, skin toxicity, and peripheral neurotoxicity induced by cancer treatment, as well as osseous complications, extravasation, and side effects of radiotherapy...

Purpose In patients with metastatic castration-resistant prostate cancer (mCRPC), overall survival (OS) is significantly improved with cabazitaxel versus mitoxantrone after prior docetaxel treatment. FIRSTANA ( ClinicalTrials.gov identifier: NCT01308567) assessed whether cabazitaxel 20 mg/m(2) (C20) or 25 mg/m(2) (C25) is superior to docetaxel 75 mg/m(2) (D75) in terms of OS in patients with chemotherapy-naïve mCRPC. Patients and Methods Patients with mCRPC and Eastern Cooperative Oncology Group performance status of 0 to 2 were randomly assigned 1:1:1 to receive C20, C25, or D75 intravenously every 3 weeks plus daily prednisone...

Vincristine (VNC) is commonly used to treat pediatric cancers, including the most prevalent childhood malignancy, acute lymphoblastic leukemia. Although clinical evidence suggests that VNC causes peripheral neuropathy in children, the degree to which pediatric chemotherapeutic regimens influence pain sensitivity throughout life remains unclear, in part because of the lack of an established animal model of chemotherapy-induced neuropathic pain during early life. Therefore, this study investigated the effects of VNC exposure between postnatal days (P) 11 and 21 on mechanical and thermal pain sensitivity in the developing rat...

PURPOSE OF REVIEW: Chemotherapy-induced peripheral neuropathy (CIPN) is a common, frequently chronic condition characterized by pain and decreased function. Given the growing number of cancer survivors and an increasing recognition of opioid therapy limitations, there is a need for critical analysis of the literature in directing an informed and thoughtful approach for the management of painful CIPN. RECENT FINDINGS: A PubMed search for 'chemotherapy-induced peripheral neuropathy AND pain' identifies 259 publications between 1 January 2016 and 31 March 2017...

Many chemotherapy treatments induce peripheral neuropathy (CIPN). These patients often experience neuropathic pain (NP) that reduces the quality of life. The aim of this prospective, open label study was to evaluate the efficacy and tolerability of tapentadol (TP) in patients affected by CIPN. CIPN were consecutively enrolled in a prospective open label study at the Neuro-Oncology Unit of the Regina Elena National Cancer Institute in Rome. During the titration phase, each patient initially received doses of TP 50 mg twice a day...

Oxaliplatin (L-OHP) is a platinum-based anticancer agent used to treat various types of cancer. It frequently causes acute and chronic peripheral neuropathies, such as cold allodynia and mechanical hyperalgesia. Ninjin'yoeito (NYT) is a formula used in traditional Japanese Kampo medicine to improve recovery from diseases and other medical disorders. We previously reported that treatment with a boiling-water extract of NYT prevented L-OHP-induced damage to neurite-like outgrowths from differentiated PC12 cells...

Although cisplatin (CDDP) is a key drug in cancer chemotherapy, CDDP-induced peripheral neuropathy is a dose-limiting factor. We previously reported that CDDP-induced peripheral neuropathy, which progressed from allodynia to hypoalgesia, was ameliorated by the administration of CDDP to rats at a specific time. However, mechanical allodynia cannot be prevented therapeutically. Pregabalin (PGN) is used to suppress neuropathic pain from herpes zoster and diabetes. Therefore, we investigated the effects of PGN on CDDP-induced mechanical allodynia in rats...

Peripheral neuropathy (PN) is very prevalent in cancer patients and a leading cause of pain related to cancer. However, the underlying pathophysiological mechanisms vary significantly. Peripheral neuropathy can be a direct or an indirect complication of cancer or cancer-related treatment, or a pre-existing comorbidity not related to cancer. PN might also occur as a paraneoplastic neurological syndrome. Such syndromes are immune-mediated manifestations that usually precede the diagnosis of cancer or cancer's relapse...

Chemotherapeutic drugs, including bortezomib, often cause painful peripheral neuropathy, which is a severe dose-limiting adverse effect experienced by many cancer patients. The glutamate N-methyl-d-aspartate receptors (NMDARs) at the spinal cord level are critically involved in the synaptic plasticity associated with neuropathic pain. In this study, we determined whether treatment with bortezomib, a proteasome inhibitor, affects the NMDAR activity of spinal dorsal horn neurons. Systemic treatment with bortezomib in rats did not significantly affect postsynaptic NMDAR currents elicited by puff application of NMDA directly to dorsal horn neurons...

Although there is an unmet need for pain medications that are both effective and safe, virtually no novel analgesics have been approved over the past two decades. In view of both experimental and clinical evidence of a major role for nerve growth factor (NGF) in the generation and maintenance of a wide range of pain states, the clinical development of humanised anti-nerve growth factor monoclonal antibodies (anti-NGF mAbs) aroused particular interest. However, the US Food and Drug Administration (FDA) placed a clinical hold on anti-NGF mAb clinical studies in late 2010, first because of reports of serious joint-related adverse events, and afterwards because of sympathetic nervous system safety concerns...
