Evaluation of the Efficacy of Donepezil in the Treatment of Oxaliplatin-induced Peripheral Neuropathy: Proof of Concept Study
The use of oxaliplatin in the treatment of colorectal or pancreas cancer induces (>75% of patients) severe sensorimotor neuropathy decreasing the quality of life of cancer survivors. Today, no treatment remains univocal for these peripheral neuropathies. But preclinical works have demonstrated that donepezil (acetylcholinesterase inhibitor use for Alzheimer's disease) was able to prevent and treat neuropathic symptoms in oxaliplatin-treated rats. Present study aims to assess the therapeutic efficacy of donepezil on oxaliplatin-induced peripheral neuropathy (OIPN) in cancer survivors. Bibliographic data suggests an antineuropathic effect of donepezil in human and animal models. In clinic, a study have shown in healthy volunteers that donepezil (associated with gabapentin) reduced the pain threshold (better than gabapentin alone) caused by stimulation of the sural nerve, without severe adverse effect. Similarly, two studies in patients with neuropathic pain demonstrated that donepezil increases analgesic effect of gabapentin. Finally, a case report demonstrated an analgesic effect of donepezil in painful Alzheimer's disease patients. In animals, several studies demonstrated that donepezil induces analgesic and neuroprotective effects. Recently, a preclinical study demonstrated that donepezil induced antineuropathic effect in diabetic mice with neuropathic pain. Research unit INSERM U1107 (partner of the DONEPEZOX study) demonstrated the antineuropathic effects of donepezil in several animal models of chemotherapy-induced peripheral neuropathies, and very recently, a study have confirmed these results with oxaliplatin and cisplatin. These clinical and preclinical data have thus highlighted the potential beneficial effect of donepezil on neuropathic symptoms, without any significant adverse effects. Therefore the hypothesis is that the use of donepezil could reduce the symptoms of OIPN, limit the decrease in quality of life and the appearance of comorbidities (anxiety/depression) in cancer survivors. For this purpose, the investigators propose here a proof of concept, multicentre, phase II, randomised, double-blind, placebo-controlled clinical study. The primary objective will be the curative efficacy of donepezil on the severity of OIPN in patients who have completed oxaliplatin-based chemotherapy for the treatment of colorectal or pancreas cancer and have peripheral neuropathy of grade ≥2. This will be assessed using the EORTC QLQ-CIPN20 sensory scale. Our methodological choice to use the QLQ-CIPN20 as the primary endpoint will allow us to more accurately (and in a standardized manner) characterize neuropathic symptoms and assess the therapeutic effect of donepezil on these symptoms. In addition, as secondary objectives, we will study the effect of donepezil on neuropathic pain, the intensity of neuropathic symptoms, health-related quality of life, and the tolerance of donepezil. The 80 patients required will be randomized (1:1) to receive either placebo or donepezil (5 mg daily for 4 weeks and then 10 mg daily for 12 weeks as a single dose and according to tolerance and efficacy). Patients will be followed for 1 month after the end of treatment to assess the OIPN. As a proof of concept study, responder rate will be assessed only for Donepezil arm (primary objective) and compared between each treatment arm (secondary objective) after a minimum of 12 weeks of treatment. A responder will be defined as a patient with a decrease of neuropathic grade according to CIPN20 sensory score compraed to baseline.

Prevalence of Peripheral Neuropathy Among Patients With Auditory Neuropathy
Auditory neuropathy/ dys-synchrony/ peri-synaptic audiopathy (AN) are terms used to describe a specific hearing disorder with a disturbed auditory neural response in presence of normal cochlear function. Initially reported as early as the 1970s by ( Hinchcliffe et al) after observation of the patients with normal hearing thresholds, who had difficulty to detect the sounds especially in presence of background noise . Auditory Neuropathy is characterized by five integral features that distinguish it from other types of hearing loss. These are: Variable audiometric results anywhere from normal hearing to Sensorineural hearing loss of any degree up to profound hearing loss showing unusual audiometric pattern , Preserved outer hair cells (OHCs) responses such as otoacoustic emissions (OAEs) and/or cochlear microphonics (CM) , Altered neural processing such abnormal auditory brainstem responses (ABRs) with a reduced or absent wave V , Poor speech perception with poor speech recognition score that seems out of proportion compared to their pure-tone detection thresholds. , absent stapedial reflexes to the ipsilateral and contralateral tone at a 110-dB hearing level . In 2008 it was found that AN does not represent a single disease entity but it is a heterogeneous disease category with a wide range of hearing loss types ,etiologies , age and clinical manifestations hence the adoption of the term auditory neuropathy spectrum disorder (ANSD) by an International Newborn Hearing Screening Conference held in Italy following a comprehensive study of newborn hearing test results. The prevalence of ANSD is variable in published studies from (0.23 to 15%) among hearing impaired individuals . Regarding the underlying etiological factors, auditory neuropathy can be congenital or acquired . AN without the involvement of the neurological system has been termed as primary auditory neuropathy (PAN). Peripheral neuropathy is not a constant finding in all patients with this hearing disorder , AN may occur in the afferent pathway of acoustic nerve, probably accompanied by the pathological changes of efferent nerve in the olivocochlear system inside the brainstem Our study is conducted to detect the prevalence of peripheral neuropathy among patients with auditory neuropathy spectrum disorder .

Chemotherapy Induced Peripheral Neuropathy (CIPN): A Pilot Study of Intraneural Facilitation for Managing Chemotherapy-Induced Peripheral Neuropathy
Chemotherapy induced peripheral neuropathy (CIPN) is a common side effect of many forms of chemotherapy having a negative impact on the quality of life for cancer survivors due to numbness, decreased sensation, pain (of various intensities in the extremities), gait/balance problems, and difficulty with fine motor skills of the hands and fingers.To date, there are no preventive modalities to mitigate CIPN development.When CIPN becomes intolerable, optimal doses of chemotherapy have to be reduced or discontinued, which may affect a patient's overall survival. Intraneural facilitation (INF) is a technique developed by physical therapists at Loma Linda University after careful study of the structure, pathophysiology and biomechanics of peripheral nerves. The focus of INF is restoration of circulation to an ischemic nerve. INF has been offered to subjects receiving treatment at LLUCC with anecdotal success. The purpose of this study is to evaluate INF as a treatment modality under the rigor of scientific inquiry to determine its effectiveness as a viable treatment option for breast cancer patients with CIPN.

A View Of Perceived Symptoms Associated With Chemotherapy-Induced Peripheral Neuropathy In Patients With Breast Cancer
Breast cancer remains the most frequent type of cancer globally. Nevertheless, the increased rate of disease-free survival of breast cancer brought the specific need of managing of short and long-term side effects of multimodal treatment. Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most debilitating conditions which is characterized by a wide variety of experienceable symptoms by patients that need to be addressed in detail. Therefore, in this cross-sectional study, it was aimed to assess the potential symptoms associated with CIPN of patients with breast cancer who underwent systemic chemotherapy. In addition, it was aimed to assess the potential associations between experienced symptoms of CIPN and sociodemographic (age, body mass index etc.) and clinical features (mean exposed dose, type of surgery (if any) etc.).
