A biomedical study was undertaken at the Institute of Nutrition and Food Science, University of Dhaka to observe the effect of the antioxidative roles of vitamins A and E on the degenerative process occurring in spondylosis in human. A single and a double blind study were done. Thirty two patients suffering from spondylosis were selected for the study on the basis of certain criteria. The serum vitamin E level in most of the patients were lower (5.8 +/- 2.7 umol/L) than normal (11-41 umol/L). Vitamin E administration at a dose of 100 mg daily for three weeks resulted in a significant increase in serum vitamin E level accompanied by complete relief of pain. The serum vitamin A level of the patients were already within the normal (0.53-2 umol/L) range and vitamin A administration was not effective in relieving the pain. The results therefore strongly indicate that vitamin E is effective in curing spondylosis and most probably due to its antioxidant activity.

IRFI 016 has demonstrated significant antioxidant activity, inhibiting hepatic lipid peroxidation (rat intoxicated by CCl4) and the formation of gastric lesions by ethanol (rat). This activity proved equal to or better than that exhibited by the most investigated antioxidant/radical scavenger agents (such as BHA, BHT, Vitamin E). The drug markedly increased mucus production (rabbit, mouse) by all the administration routes used (os, i.v. and inhalatory) and proved more active than, or overlapping, the most noted mucoregulatory/mucolytic drugs (sobrerol, bromexine, thiopronine, ambroxol, N-acetylcysteine) which were chosen for comparison. The tracheo-bronchial mucus viscosity was also significantly reduced (bronchitic animals) as was the fucose and total protein content. In the pigeon, IRFI 016 improved mucociliary clearance. Moreover IRFI 016 evidenced anti-inflammatory activity nearly equal to that exhibited by ASA and phenylbutazone (carrageenin oedema, abcesses and inflammatory pain).

Thirty-two typical patients with breast cancer, aged 32-81 years and classified 'high risk' because of tumor spread to the lymph nodes in the axilla, were studied for 18 months following an Adjuvant Nutritional Intervention in Cancer protocol (ANICA protocol). The nutritional protocol was added to the surgical and therapeutic treatment of breast cancer, as required by regulations in Denmark. The added treatment was a combination of nutritional antioxidants (Vitamin C: 2850 mg, Vitamin E: 2500 iu, beta-carotene 32.5 iu, selenium 387 micrograms plus secondary vitamins and minerals), essential fatty acids (1.2 g gamma linolenic acid and 3.5 g n-3 fatty acids) and Coenzyme Q10 (90 mg per day). The ANICA protocol is based on the concept of testing the synergistic effect of those categories of nutritional supplements, including vitamin Q10, previously having shown deficiency and/or therapeutic value as single elements in diverse forms of cancer, as cancer may be synergistically related to diverse biochemical dysfunctions and vitamin deficiencies. Biochemical markers, clinical condition, tumor spread, quality of life parameters and survival were followed during the trial. Compliance was excellent. The main observations were: (1) none of the patients died during the study period. (the expected number was four.) (2) none of the patients showed signs of further distant metastases. (3) quality of life was improved (no weight loss, reduced use of pain killers). (4) six patients showed apparent partial remission.

Pravastatin is a new lipid-lowering drug belonging to the class of 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase inhibitors. Since 1986, more than 15,000 patients have received pravastatin in sponsored clinical research trials with more than 21,000 cumulative patient-years of exposure to the drug. Analysis of long-term follow-up data from 1142 patients participating between 1986 and 1990 in six core randomized clinical trials in the United States confirms the favorable safety profile of pravastatin. Rash, gastrointestinal complaints, musculoskeletal pain, and elevations in liver transaminase levels, whether or not attributed to treatment, were the most common reasons for patients withdrawing from these trials. Ophthalmologic monitoring revealed no adverse effects on the crystalline lens. Safety assessments continue for two core trials in more than 400 patients with up to 7 years of continuous follow-up. The effects of pravastatin on serum cholesterol levels are not influenced by the age, sex, weight, or initial cholesterol level of the patient. Vitamin E, A, and D metabolism remain normal during treatment. Combination therapy with pravastatin and bile-acid-binding resins or niacin is well tolerated, with additive effects on low-density lipoprotein cholesterol. There is limited experience with the combination of pravastatin and gemfibrozil or cyclosporine. An ongoing arteriosclerosis research program with more than 21,000 patients enrolled will further define the long-term safety of pravastatin and its effects on atherosclerosis progression, as well as its role in the primary and secondary prevention of coronary heart disease.

A case report is presented of an electrophysiologic recovery from vitamin E-deficient neuropathy after treatment with water-soluble vitamin E in a patient with chronic hepatobiliary disease. The patient was a 64-year-old man who had experienced progressive difficulty in ambulation, with ataxia, over the previous 3 years. The symptoms were associated with pain, tingling sensation in the extremities, and reduced fine motor activity. The patient had chronic hepatobiliary disease, with recurrent cholangitis and external drainage of bile acid through a T-tube for more than 20 years. Vitamin E level was barely detectable (<0.5 mg/L). Sensory conduction was absent in both sural nerves. Other sensory and motor conduction studies in the upper and lower extremities showed decreased amplitude. The patient was treated with water-soluble vitamin E. After 4 months of therapy, his ambulation function improved, but pain and tingling sensation in both hands remained. Sensory nerve action potentials appeared in both sural nerves, and amplitudes of other sensory nerves were increased. In a second follow-up study after 9 months, all of the evaluated parameters in the nerve conduction studies, as well as the vitamin E level, were normal. The authors conclude that vitamin E-deficient neuropathy is reversible and electrophysiologic recovery can occur with water-soluble vitamin E therapy.

It has been recently reported that intralesional therapy with alpha interferon 2B resulted in significant improvement of both objective and subjective complaints (penile curvature, pain, plaque size, sexual function) associated with Peyronie's disease. Vitamin E, with its antioxidant properties, may play a role in reducing the inflammatory response. This study was designed to determine the safety and effectiveness of a high dose of alpha INF-2B injected weekly into the Peyronie's plaque combined with oral Vitamin E therapy. Twenty-nine patients with Peyronie's disease were evaluated with penile duplex Doppler for degree of penile curvature, deformity, and plaque size both prior to and after treatment. Each patient then received 4.0 x 10(6) units of alpha INF-2B in 10 cc of normal saline after appropriate local anesthesia. Injections were given once per week directly into the Peyronie's plaque for a period of 10 weeks. Patients also received 400 units of Vitamin E by mouth twice a day. Subjective data was obtained via a questionnaire prior to and at the conclusion of the study. Preliminary results demonstrated improvement of penile curvature in 39% of patients, with one patient experiencing complete resolution. Significant decreases in plaque sizes were noted in 11 of these patients, with softening of the plaques noted in all patients completing the study. Seven patients dropped out of the study prior to completing the 10 weeks: three with severe disease proceeded to surgery, two were lost to follow-up, one had exascerbation of his arthritis symptoms, and one quit secondary to flu-like symptoms. Subjective data from questionnaires revealed improvement in sexual function in those men with decreased curvature and plaque size. Weekly intralesional injections with 4.0 x 10(6) units improved plaque consistency and decreased curvature and plaque size (P < 0.5). Overall subjective sexual performance was reportedly improved. Increased dosage of alpha INF-2B resulted in increased severity of flu-like symptoms when compared to the lower (1 x 10(6) units) biweekly dosage. No significant difference was noted with the addition of oral Vitamin E therapy.

The adjuvanticity of two gamma inulin/liposomes/Vitamin E combinations was evaluated in the mouse, in contraceptive vaccines with sperm protein extracts or a synthetic HE2 peptide ("Human Epididymis gene product"; residues 15-28) as antigen. The HE2 peptide was not conjugated to a protein carrier, to ensure that the antibodies elicited were specific against the HE2 peptide. The adjuvant combinations were designed to increase adjuvanticity, as their components have complementary mechanisms, and their performance was compared to Freund's adjuvant. Antibody production against native sperm structures was determined in sera by ELISA immunoassay and immunohistology. Toxicity of adjuvants was determined by histopathological study and treated mice were monitored for signs of pain or distress. Our results show that the gamma inulin (1-2 microm particle size)/liposomes/Vitamin E combination, with sperm protein extracts, is better than Freund's adjuvant because it elicits good antibody titres without any toxicity. When the synthetic HE2 peptide is used as antigen, the gamma inulin (1-2 microm particle size)/liposomes/Vitamin E combination is less effective than Freund's adjuvant; nevertheless, the anti-HE2 antibodies elicited are highly specific and recognize native structures in sperm.

Healing of wounds, whether from accidental injury or surgical intervention, involves the activity of an intricate network of blood cells, tissue types, cytokines, and growth factors. This results in increased cellular activity, which causes an intensified metabolic demand for nutrients. Nutritional deficiencies can impede wound healing, and several nutritional factors required for wound repair may improve healing time and wound outcome. Vitamin A is required for epithelial and bone formation, cellular differentiation, and immune function. Vitamin C is necessary for collagen formation, proper immune function, and as a tissue antioxidant. Vitamin E is the major lipid-soluble antioxidant in the skin; however, the effect of vitamin E on surgical wounds is inconclusive. Bromelain reduces edema, bruising, pain, and healing time following trauma and surgical procedures. Glucosamine appears to be the rate-limiting substrate for hyaluronic acid production in the wound. Adequate dietary protein is absolutely essential for proper wound healing, and tissue levels of the amino acids arginine and glutamine may influence wound repair and immune function. The botanical medicines Centella asiatica and Aloe vera have been used for decades, both topically and internally, to enhance wound repair, and scientific studies are now beginning to validate efficacy and explore mechanisms of action for these botanicals. To promote wound healing in the shortest time possible, with minimal pain, discomfort, and scarring to the patient, it is important to explore nutritional and botanical influences on wound outcome.

Palmar-plantar erythrodysesthesia (PPE) is a distinctive and relatively frequent toxic reaction related to some chemotherapeutic agents. Doxorubicin, cytarabine, docetaxel, fluorouracil, and capecitabine are the most frequently implicated agents. Recently, taxanes, especially docetaxel, have been widely used in combination with capecitabine in patients with metastatic breast cancer (MBC). A high percentage of PPE has been seen in patients undergoing this combination therapy. PPE seems to be dose dependent and both peak drug concentration and total cumulative dose determine its occurrence. Withdrawal or dose reduction of the implicated drug usually gives rise to amelioration of the symptoms. Supportive treatments such as topical wound care, elevation, and cold compresses may help to relieve the pain. Use of systemic corticosteroids, pyridoxine (vitamin B6), blood flow reduction, and, recently, topical 99% dimethyl-sulfoxide have been used with variable outcomes. Vitamin E treatment has not been published before, especially without dose reduction of docetaxel-capecitabine therapy. Here we present five MBC patients treated with docetaxel-capecitabine combination therapy in whom PPE was observed during the clinical follow-up period. In all patients grade 2-3 PPE was observed. Vitamin E therapy was started at 300 mg/day p.o. without dose reduction of therapy and after 1 week of treatment PPE began to disappear. We suggest that it could be of interest to consider vitamin E as a preventive drug when drugs with a strong association with PPE are going to be administered.

Recent studies suggest that reactive oxygen species (ROS) are critically involved in neuropathic pain. Although vitamin E is a well-known antioxidant, its efficacy on chronic pain is not known. This study investigated the efficacy and mechanisms of vitamin E analgesia in a rat model of neuropathic pain produced by spinal nerve ligation. The effects of vitamin E were investigated using behavioral testing, electrophysiological recording of dorsal horn neurons, and determinations of phosphorylated NMDA receptor subunit 1 (pNR1) levels in the spinal dorsal horn. Results showed that a systemic single injection of a high dose or repetitive daily injections of low doses of vitamin E significantly reduced neuropathic pain behaviors. Vitamin E was also effective in producing analgesia by intrathecal injection, suggesting the importance of spinal mechanisms. In spinal dorsal horn neurons, vitamin E reduced evoked responses to mechanical stimuli as well as the sizes of their receptive fields. In addition, levels of pNR1 in neuropathic rats were also reduced by vitamin E injection. These data suggest that vitamin E produces analgesia in neuropathic rats that is, at least in part, mediated by reducing central sensitization which, in turn, is induced by peripheral nerve injury.
