Patients with chronic hepatitis C virus (HCV) infection experience a range of symptoms including depression, fatigue and neurocognitive deficits, impairing quality of life. Depression, in particular, may be reactive to increased psychosocial stress, and the physical symptoms of advanced HCV or associated comorbidities. However, even patients at an early stage of HCV infection, with minimal hepatic inflammation or comorbidities, report more depressive symptoms and fatigue than the general population. Similarly, specific neurocognitive deficits occur in early stage HCV infection and are independent of the presence of depression or encephalopathy...

Peripheral nerve blockade (PNB) is a conventional strategy for the management of acute postoperative pain. However, the short duration of the associated analgesia and the potential systemic toxicity due to the low molecular weights of local anesthetics limit their application. Methods: An in situ forming injectable Gel-microsphere (Gel-MS) system consisting of PLGA-PEG-PLGA Gel (Gel) and Gel-immobilized bupivacaine-loaded microsphere (MS/BUP) was prepared for precision-guided long-acting analgesia. A series of in vitro characterizations, such as scanning electron microscopy, rheology analysis, confocal laser scanning microscopy, drug release, and erosion and degradation, were carried out...

The dipeptide amide H-Phe-Phe-NH2 (1) that previously was identified as a ligand for the substance P 1-7 (SP1-7 ) binding site exerts intriguing results in animal models of neuropathic pain after central but not after peripheral administration. The dipeptide 1 is derived from stepwise modifications of the anti-nociceptive heptapeptide SP1-7 and the tetrapeptide endomorphin-2 that is also binding to the SP1-7 site. We herein report a strong anti-allodynic effect of a new H-Phe-Phe-NH2 peptidomimetic (4) comprising an imidazole ring as a bioisosteric element, in the spare nerve injury (SNI) mice model after peripheral administration...

Chronic occupational exposure to carbon disulfide (CS2) has debilitating motor and sensory effects in humans, which can increase the risk of falls. Although no mention of vestibulotoxic effects is contained in the literature, epidemiological and experimental data suggest that CS2 could cause low-frequency hearing loss when associated with noise exposure. Low-frequency noise might also perturb the peripheral balance receptor through an as-yet unclear mechanism. Here, we studied how exposure to a low-frequency noise combined with 250-ppm CS2 affected balance in rats...

Background Persistent pain after breast cancer treatment (PPBCT) is a considerable clinical problem affecting between 25 and 60% of breast cancer survivors [1]. Several risk factors have been proposed, among them nerve damage caused by adjuvant treatment [2]. Taxanes used in adjuvant therapy for breast cancer are neurotoxic, and thereby being a potential risk factor for PPBCT and sensory disturbances. However, the long term influence of taxanes on PPBCT is not well documented. Thus, the aim of this study was therefore to compare a nationwide cohort treated with cyclophosphamide and epirubicin + docetaxel (CE + T) versus a nationwide cohort treated with cyclophosphamide, epirubicin and fluoruracil (CEF), in order to assess differences in reporting of PPBCT, sensory disturbances in surgical area, symmetric peripheral sensory disturbances, and functional impairment...

BACKGROUND: Neuroblastoma survivors may be at elevated risk for psychological impairments because of their young age at diagnosis and neurotoxic treatment, but this is not well described. METHODS: A total of 859 ≥5-year survivors of neuroblastoma younger than 18 years (diagnosed in 1970-1999), who had a median age at diagnosis of 0.8 years (range: 0.0-7.3 years) and a median follow-up of 13.3 years (range: 8.0-17.9 years), were compared with 872 siblings of childhood cancer survivors who were younger than 18 years with the parent-reported Behavior Problem Index (BPI) for psychological functioning...

Cytotoxic compounds vincristine sulphate (VCR) is widely used to against hemato-oncology, and especially the acute lymphoblastic leukemia (ALL). However, VCR's full therapeutic potential has been limited by its dose-limiting neurotoxicity, classically resulting in autonomic and peripheral sensory-motor neuropathy. Therefore, we developed a targeted liposomal drug delivery system (sgc8/VCR-Lipo) for improving the therapeutic effects of VCR against leukemia and reducing its systematic adverse effects. sgc8/VCR-Lipo could specifically bind to CCRF-CEM cells and significantly inhibit proliferation of cancer cells in vitro and tumor growth in vivo...

Peripheral nervous system neurotoxicity is the most problematic complication of cisplatin treatment. In this study, we have addressed the possible neuroprotective effect of canagliflozin on cisplatin-induced peripheral neurotoxicity in rats. Rats were randomly allocated into the following: control (vehicle) group, received hydhroxypropyl methyl cellulose; cisplatin group, injected cisplatin 2 mg/kg intraperitoneal, twice a week for 5 consecutive weeks; canagliflozin-cisplatin of received canagliflozin, 10 mg/kg/day by gavage and cisplatin in the same schedule like cisplatin group...

BACKGROUND/AIM: Mounting evidence suggests that trophic cell signaling can be mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) activation. It has been demonstrated that exogenous application of brain-derived neurotrophic factor (BDNF) is highly neuroprotective in vitro against neurotoxic insults such as standard chemotherapies. MATERIALS AND METHODS: Because positive allosteric modulation of AMPARs with ampakines can increase both BDNF mRNA and protein in vitro and in vivo, we examined whether application of the ampakines CX614 and CX729 promoted neuroprotection against staurosporine-induced cell death in rat primary cortical neurons using propidium iodide to stain for dead cells...

Oxaliplatin is a key drug in the treatment of advanced metastatic colorectal cancer. Despite its beneficial effects in tumor reduction, the most prevalent side-effect of oxaliplatin treatment is a chemotherapy-induced neuropathy that frequently forces to discontinue the therapy. Indeed, along with direct damage to peripheral nerves, the chemotherapy-related neurotoxicity involves also the central nervous system (CNS) as demonstrated by pain chronicity and cognitive impairment (also known as chemobrain), a newly described pharmacological side effect...

Importance: In light of the excellent long-term survival of childhood cancer patients, it is imperative to screen for factors affecting health, function, and quality of life in long-term survivors. Objective: To comprehensively assess chemotherapy-induced peripheral neuropathy in childhood cancer survivors to define disease burden and functional effect and to inform screening recommendations. Design, Setting, and Participants: In this cross-sectional observational study, cancer survivors who were treated with chemotherapy for extracranial malignancy before age 17 years were recruited consecutively between April 2015 and December 2016 from a single tertiary hospital-based comprehensive cancer survivorship clinic and compared with healthy age-matched controls...

OBJECTIVES: Chemotherapy-induced peripheral neuropathy (CIPN) is a common chemotherapy side effect, but its prevention and treatment remains a challenge. Neurotoxicity may lead to dose limitation or even treatment discontinuation, and therefore potentially affect the efficacy of anticancer treatment and long term outcomes. The practice to administer gabapentin for neuropathy may be applicable, but is limited by insufficient studies. The aim of our study was to assess the presence of chemotherapy-induced peripheral neuropathy in ovarian cancer patients treated with first-line paclitaxel and carboplatin chemotherapy and evaluate the effectiveness of gabapentin in treatment of this condition...

Paclitaxel is a chemotherapeutic agent that is effective against ovarian, breast, lung, and other cancers. Although peripheral neurotoxicity is among the most common side effects of paclitaxel treatment, central neurotoxicity is rarely reported. When centrally mediated side effects are observed, they are attributed to Cremophor EL™ (CrEL), a surfactant-containing vehicle used for paclitaxel administration. In the present report, we discuss the case of a 72-year-old woman with ovarian carcinoma who experienced a non-convulsive seizure following administration of a CrEL-free, polymeric micelle formulation of paclitaxel...

Hereditary sensory neuropathy type 1 (HSN-1) is a peripheral neuropathy most frequently caused by mutations in the SPTLC1 or SPTLC2 genes, which code for two subunits of the enzyme serine palmitoyltransferase (SPT). SPT catalyzes the first step of de novo sphingolipid synthesis. Mutations in SPT result in a change in enzyme substrate specificity, which causes the production of atypical deoxysphinganine and deoxymethylsphinganine, rather than the normal enzyme product, sphinganine. Levels of these abnormal compounds are elevated in blood of HSN-1 patients and this is thought to cause the peripheral motor and sensory nerve damage that is characteristic of the disease, by a largely unresolved mechanism...
