Alcohol-Induced Neuropathy In Chronic Alcoholism: Causes, Pathophysiology, Diagnosis, And Treatment Options Current Pathobiology Reports

Alcoholic Neuropathy:

It is important to supplement the diet with vitamins, including thiamine and folic acid. Physical exam findings include diminished sensation to vibration, pain, dysfunctional thermo-proprioception, weakness in the ankle and toes with flexion and extension, atrophy of foot muscles, gait ataxia, and diminished deep tendon reflexes. Some of the most common symptoms are numbness or tingling sensation of the extremities, pain or a burning sensation in the extremities, difficulty walking, difficulty urinating, and difficulty talking or swallowing. A doctor may also want to test the functioning of the kidneys, liver, and thyroid.

Nerve damage can also make it difficult for you to carry out the functions of daily life. This review focuses on the many pathways that play a role in the onset and development of alcohol-induced neuropathy, as well as present the possible treatment strategies of this disorder, providing insights into a further search of new treatment modalities. A person can improve their outlook by significantly reducing or cutting off their alcohol intake and ensuring that they are receiving the right balance of nutrients.

Translocation of NFk’ to the nucleus has been reported to result in activation of the endogenous proteolytic enzyme system caspases [69]. Joseph & Levine [71] suggested that activity in signaling pathways that ultimately lead to apoptosis plays a critical role in the generation of neuropathic pain, before death of sensory neurones becomes apparent. Activator and effector caspases, defining components of programmed cell death signalling pathways, also contribute to pain-related behaviour in animals with small fibre peripheral neuropathies. The death receptor ligand, tumour necrosis factor a, and its downstream second messenger, ceramide, also produce pain-related behaviour via this mechanism. This suggests that these pathways are potential targets for novel pharmacological agents for the treatment of inflammatory as well as neuropathic pain [71]. Thiamine serves as an important coenzyme in carbohydrate metabolism and neuron development.

Other coexisting, alcohol-related diseases may induce exacerbation of AAN symptoms. It was shown that patients with liver cirrhosis (regardless of its etiology) present dysfunctions in ANS, primarily within the vagus nerve [170]. Proposed mechanisms include circulatory disturbances in liver cirrhosis, metabolic and neurohormonal (renin-angiotensin-aldosterone system) dysfunctions, excessive nitric oxide production, oxidative stress, and inflammatory mediators [11, 171]. There is a strong correlation between AAN and Child-Pugh scale which suggests that liver cirrhosis progression is related to impairments in ANS [172].

In studying the causes of polyneuropathy in alcoholics, most experts point to poor nutrition and the toxicity of long-term alcohol exposure. Many people who use alcohol neglect their diet, either eating too much or too little of essential nutrients important to maintaining good health. They will be prescribed the smallest dose of medicine needed to reduce symptoms. This may help prevent drug dependence and other side effects of chronic use. Seek medical care right away if you notice unusual tingling, weakness, or pain in your hands or feet. Early diagnosis and treatment give you the best chance for controlling your symptoms and preventing further damage to your peripheral nerves.

The medical community has recognized that addiction is a disease and that some people are predisposed to it. As a result, it is usually necessary to get medical help to manage alcohol use disorder. Among them, pure large fiber neuropathy was found in 18 patients, pure small fiber neuropathy in 12 patients, and both large and small fiber neuropathy was diagnosed in 24 patients. Elevated liver enzymes and fasting glucose levels upon admission were significantly correlated with neuropathy. Lower blood thiamine levels (than reference) were found in seven patients and were not correlated with neuropathy. For all animals, food intake and body weight were measured twice a week.

Later on, weakness appears in the extremities, involving mainly the distal parts. Progressively, the sensory and motor symptoms and signs extend proximally into the arms and legs and finally the gait may become impaired [11]. Progression of symptoms is usually gradual, continuing over months or years [2, 4].

Semi-thin slices (500 nm), one cut for each slice totaling five cuts per nerve were performed with the aid of an ultramicrotome (Leica Inc UC6 – Wetzlar/Germany) and were subsequently stained with alcoholic toluidine blue and analyzed by the stereological method. For the neurological domain, we evaluated the muscle tone parameters (forelimb grip strength and hypotonia), gait and equilibrium parameters (righting reflex and gait), and CNS excitation parameters (twitches, clonic and tonic convulsions). Regarding the autonomic domain, we evaluated lacrimation, pupil size, palpebral closure, salivation, piloerection, and breathing parameters. The behavioral domain was assessed by observation of spontaneous activity (hyperactivity), affective response (reactivity to catching and handling, defecation, and urination), and sensorial responses (touch response and tail-pinch response).

It was observed that abstinence may lead to the regression of several symptoms of AAN [159]. Alcoholic neuropathy is a condition in which the nerves become damaged as a result of years of heavy alcohol consumption. Symptoms include burning pain in the body, hyperalgesia (increased sensitivity to pain), and allodynia (a condition in which normal stimulus, like a soft touch, produces pain).

Conversely, we assured that the animals would be exposed to eight weeks of treatment as it is a time length capable of inducing systemic changes to reproduce alcohol-related peripheral neuropathy (Mellion et al. 2013). Vitamin E is used to refer to a group of fat-soluble compounds that include both tocopherols and tocotrienols. Treatment with vitamin E was found to be beneficial source in the treatment of patients with diabetic peripheral neuropathy [104] and neuropathic pain in streptozotocin-induced diabetic rats [105]. Recently findings from our laboratory also suggest the benefecial effects of both a-tocopherol and tocotrienol, isoforms of vitamin E, in the prevention of hyperalgesia and allodynia in rats administered ethanol for 10 weeks [55].

Light touch can feel exaggerated and painful, particularly in the fingers and toes. Alcoholic neuropathy is one of the most common but least recognizable consequences of heavy alcohol use. People with a long history of alcohol misuse might experience loss of balance, pain, tingling, weakness, or numbness after drinking alcohol. In an inpatient facility, you will cut off the alcohol consumption and allow the body to recover properly. When it comes to treating the condition, it is best to abstain from alcohol and restore your nutrient balance. With a healthy diet, you can halt its effect on the nerves and move to a full or partial recovery.

The morphological basis of post-alcoholic damage of neural tissue includes primary axonopathy and secondary demyelination of motor and sensory (especially small) fibers [105]. Demyelination is probably the effect of axoplasmic transmission slowdown; such degeneration so-called dying back bears semblance to Wallerian degeneration [64, 84]. An animal study on axonal transport in vitro using dorsal roots of the sciatic nerve showed decreased axonal transmission after long-term ethanol consumption [106]. In vivo study on rats showed impaired retrograde axonal transport [107, 108]. Thus, ALN might be induced by the combination of the effects of the direct activity of alcohol metabolites on the nerve fibers along with nutritional deficiencies primarily in a form of thiamine deficiency.

However, the limitations of those studies include the lack of the possibility to measure the amount of vitamin B1 in the serum; further, patients who were involved in the study have received an unrefined form of the supplement. Later, the results have been supported by Victor and Adams (1961)’among 12 patients with ALN, neuropathic symptoms were alleviated just after thiamine supplementation, even though the alcohol consumption was previously completely reduced [149]. Koike et al. (2003) compared clinical and histological differences between ALN with and without thiamine deficiency [65]. Also, the results of the group of 32 patients with non-alcoholic thiamine deficiency neuropathy were considered. Thiamine deficiency resulted in the progression of sensory dysfunctions; further, histological examination of the sural nerves revealed the loss of small nerve fibers and segmental demyelination.

Recently, extended release gabapentin relieved symptoms of painful polyneuropathy [120]. Lamotrigine was effective in relieving central post stroke pain [121] and painful diabetic polyneuropathy [122], but recent larger studies have failed to show a pain relieving effect you can try here in mixed neuropathic pain [123] and painful polyneuropathy [124]. Valproate demonstrated varying effects in different studies of neuropathic pain, with three studies from one group reporting high efficacy [125’127] and others failing to find an effect [128, 129].

Progression of the disease leads to symmetrical ascending motor and sensory deficits. However, it is known to be directly related to heavy and long-term alcohol consumption. Overconsumption of alcohol may directly harm and hinder the nerves’ ability to communicate information from one body area to another. In people with they said, the peripheral nerves have been damaged by too much alcohol use. The peripheral nerves transmit signals between the body, the spinal cord, and the brain. Alcohol abuse causes a wide range of disorders that affect the nervous system.
