A cross-sectional study was designed to identify a relationship between the presence of symptoms usually related to nervous system involvement as well as other chronic complications of diabetes with three objectively defined degrees of autonomic neuropathy (AN). Symptoms usually related to peripheral sensitive neuropathy and AN were assessed using a questionnaire applied to 132 diabetics (38 IDDM and 94 NIDDM), 65 without and 67 with AN. AN was classified as follows according to 5 cardiovascular autonomic tests described by Ewing: 1) early involvement-1 abnormal test (N = 27); 2) definite involvement-2 or 3 abnormal tests (N = 26); 3) severe involvement-4 or 5 abnormal tests (N = 14). A statistically significant association was observed between degree of autonomic involvement and the presence of the following symptoms: dizziness on standing, dysphagia, vomiting, diarrhea, fecal incontinence, gustatory sweating, urinary retention, numbness and hyperesthesia of the feet or legs. Constipation and cystitis were not significantly related to cardiovascular AN. Only 3% of the patients without neuropathy and with early involvement had four or more than four of the symptoms. The prevalence of proliferative retinopathy and nephropathy was increased among patients with more severe degrees of AN. For IDDM patients there was a positive correlation between the degree of cardiovascular AN and the duration of diabetes. We conclude that: 1) severe cardiovascular AN is usually related to 4 or more of the evaluated symptoms and those patients usually have the other complications of diabetes; 2) severe AN could be a risk factor or an indicator of the same underlying process that determines the beginning of proliferative retinopathy and/or nephropathy.

The present study was undertaken to investigate the efficacy of a new, highly purified (purity greater than 91%), ethyl esterification product from natural eicosapentaenoic acid (EPA-E, C20:5 omega 3) in patients with type II diabetes mellitus (NIDDM). Hemodynamic changes were assessed at the level of the dorsalis pedis artery using an ultrasonic color Doppler duplex system before and after oral administration of EPA-E at a dose of 1800 mg/day for 48 weeks. The cross-sectional area of the dorsalis pedis artery increased significantly from 2.5 +/- 0.2 to 3.9 +/- 0.4 mm2 (48 weeks, mean +/- SE, p < 0.05). Moreover, EPA-E improved the clinical symptom (coldness, numbness) as well as the vibration perception threshold sense of the lower extremities [from 32.1 +/- 8.5 to 16.1 +/- 4.8 (48 weeks) microns]. A significant decrease of serum triglycerides was also noted by EPA-E administration. Furthermore, significant decrease of the excretion of albumin in urine [from 24.4 +/- 3.3 to 13.9 +/- 1.8 (48 weeks) mg/g.Cr, p < 0.05]. The results of this study suggest that EPA-E has significant beneficial effects on diabetic neuropathy and serum lipids as well as other diabetic complications such as nephropathy and macroangiopathy.

Antioxidant treatment has been shown to prevent nerve dysfunction in experimental diabetes, providing a rationale for a potential therapeutic value in diabetic patients. The effects of the antioxidant alpha-lipoic acid (thioctic acid) were studied in two multicenter, randomized, double-blind placebo-controlled trials. In the Alpha-Lipoic Acid in Diabetic Neuropathy Study, 328 patients with NIDDM and symptomatic peripheral neuropathy were randomly assigned to treatment with intravenous infusion of alpha-lipoic acid using three doses (ALA 1,200 mg; 600 mg; 100 mg) or placebo (PLAC) over 3 weeks. The total symptom score (TSS) (pain, burning, paresthesia, and numbness) in the feet decreased significantly from baseline to day 19 in ALA 1,200 and ALA 600 vs. PLAC. Each of the four individual symptom scores was significantly lower in ALA 600 than in PLAC after 19 days (all P < 0.05). The total scale of the Hamburg Pain Adjective List (HPAL) was significantly reduced in ALA 1,200 and ALA 600 compared with PLAC after 19 days (both P < 0.05). In the Deutsche Kardiale Autonome Neuropathie Studie, patients with NIDDM and cardiac autonomic neuropathy diagnosed by reduced heart rate variability were randomly assigned to treatment with a daily oral dose of 800 mg alpha-lipoic acid (ALA) (n = 39) or placebo (n = 34) for 4 months. Two out of four parameters of heart rate variability at rest were significantly improved in ALA compared with placebo. A trend toward a favorable effect of ALA was noted for the remaining two indexes. In both studies, no significant adverse events were observed. In conclusion, intravenous treatment with alpha-lipoic acid (600 mg/day) over 3 weeks is safe and effective in reducing symptoms of diabetic peripheral neuropathy, and oral treatment with 800 mg/day for 4 months may improve cardiac autonomic dysfunction in NIDDM.

Starr County, Texas, a Texas-Mexico border community, was the site of a study involving culturally-appropriate education and group support for Mexican Americans with type 2 diabetes. Data were collected from 63 subjects on frequency of diabetes-related symptoms during the previous month and on self-care symptom treatments. On average, subjects were 57-year-old females, diagnosed with diabetes for 10 years, and exhibiting HbA1c levels of 12.5%. Almost 50% experienced excessive urination, excessive thirst, shakiness/nervousness, and numbness and/or tingling in their extremities. More than 50% of those who experienced symptoms did not view them as serious. Only one subject checked blood sugar levels when symptoms occurred. Significantly higher mean glycosylated hemoglobin levels were found for individuals who experienced dizziness and/or chest pain compared with those who did not. A variety of self-care treatments were employed, including over-the-counter medications and home remedies.

To investigate the changes of the arteries in extremities in patients with type 2 diabetes(DM2), fifty patients with DM2(35 women and 15 men, mean aged 57.54 +/- 14.19 years old, time of DM2 diagnosed one week-26 years, without the histories of hypertension and smoking) were studied. Radial, finger, anterior tibial and dorsum pedis arteries of all subjects were examined using color Doppler Ultrasonography, 30 of 50 patients had the symptoms of extremities (e.g., numbness, coldness and pain). The Doppler examination revealed: 1. In the patient group, arterial wall became thick, rough and rigid. The atherosclerotic plaques were found inside vascular cavities in 14/50 in patient group with one patient being asymptomatic of extremities. 2. The vascular cavities in patients remarkably narrowed compared with the control group (P < 0.05). The vascular lesion worsened along with the development of the symptoms. 3. Doppler spectra in the majority of patients displayed single-peak, whereas it displayed three peaks in normal subjects with significant differences (P < 0.05). 4. The peak flow velocities in the patients increased, and this increase was related to the development of the symptoms, but no significant differences were found. Color Doppler Ultrasound examination is valuable in the evaluation of the arterial lesion of the extremities, especially at the early stage of artery diseases in patients with DM2.

Type 2 diabetes mellitus is a prevalent disease in the US which affects more than 15 million people. As the disease progresses over time, neuropathic pain can become a common complication; it is present in more than 50% of individuals with diabetes mellitus aged >60 years. The pathogenesis of diabetic neuropathy is theorized to be multifactorial. Numerous medications, some with different mechanisms of action, have been examined regarding their effects on the symptoms associated with diabetic neuropathy such as pain, paraesthesia and numbness. However, the majority of the studies have included small patient populations. Tricyclic antidepressants, amitriptyline and desipramine in particular, have been relatively well studied and shown to be effective. However, anticholinergic adverse effects may limit their usefulness and may preclude use in the elderly. Studies have also shown gabapentin to be effective and well tolerated in the treatment of diabetic neuropathy. Capsaicin cream provides another treatment option with a favourable adverse effect profile. Many other medications have been evaluated in diabetic neuropathy; however, more placebo-controlled studies with adequate patient populations need to be performed to solidify their role in treatment.

The prevalence of diabetes and resultant complications continues to increase in many countries, including Brazil. A 1-day, multicenter descriptive study involving people with type 2 diabetes was conducted 1) to identify and describe indicators of foot neuropathy and ischemia and examine their relationship, and 2) to examine the relationship between existing risk factors and patient demographic and clinical variables. Seventy-nine (79) patients with an average age of 60.9 years (SD = 13.28) participated in the study. After obtaining a history, the feet of all participants were examined (assessment, palpation, and sensitivity tests using a 128-Hz tuning fork and a 10-g Semmes-Weinstein monofilament). The majority of study participants were women (57%) and the average length of time since diagnosis of diabetes for all participants was 7.76 years (SD = 6.69). The majority of participants were found to have neuropathic and ischemic changes, risk factors for the development of ulcers, or both. Thirty-one patients (42.47%) had cramps, 29 reported numbness (39.73%), 31 (39.24%) lacked sensory perception to the monofilament, 26 (35.62%) experienced tingling, 16 had paresthesia (22.86%), 15 (19.99%) lacked vibratory perception to the tuning fork, 14 felt burning (19.44%), and six had hyperesthesia (10.34%). Certain neuropathic and ischemic changes, as well as some risk factors, were observed more often in male and aged patients, respectively. Men were significantly more likely than women to lack vibratory perception or posterior tibial pulse and to have calluses and an ingrown toenail. Claw toe, lack of sensory perception to the monofilament, lack of posterior tibial pulse, lack of hair, reduced capillary filling, onychomycosis, ingrown toenail, and varices were significantly more common in older than in younger study participants. These results reinforce the importance of regular preventive foot examinations of patients with type 2 diabetes mellitus and confirm that nursing foot care can easily be expanded to include these much-needed assessments.

Dexamethasone-cyclophosphamide pulse (DCP) is the prefered mode of therapy in pemphigus in India because it is relatively free from the side effects seen with heavy doses of daily oral steroids. One hundred forty-six pemphigus patients treated with DCP were observed for side effects of this regimen. One hundred forty mg of dexamethasone was administered IV in 200 ml of 5% dextrose over a period of 60-90 minutes on 3 consecutive days. Five hundred mg of cyclophosphamide was added on first day of the pulse and 50 mg given orally daily in the intervening period. DCP was repeated every 4 weeks and continued for 6 months after subsidence of the disease (no new lesions). Flushing over the face was the most common event recorded during the adiministration in 78 subjects followed by palpitations in 11, hiccups in 9, and numbness of feet in 6. Fourteen patients had polyurea, and 3 developed skin rash. Shivering, shooting pains along thighs, breathlessness, seizure and unilateral limb edema were observed in one patient each. Generalized weakness/malaise was the most troublesome delayed side effect in 81 (55.4%) patients; it lasted for 8-15 days after the pulse. Thirty-six (24.6%) had inadequate sleep syndrome, 23 (15.7%) had headache, 21 (14.3%) complained of arthralgias, 19 (13%) experienced alteration in taste, and 13 (9%) had diffuse hair loss. 28 females developed menstrual disturbances, and 14 (9.5%) had blurring of vision (glaucoma in 3 and posterior subcapsular cataract in 1). Thirteen of eighteen diabetics had an increase in blood sugar requiring higher doses of insulin. Five NIDDM patients needed insulin. Four (2.7%) developed hypertension. Pulse therapy is not absolutely free from side effects. Hypertension and diabetes occur less frequently as compared to conventional steroid therapy. Generalized weakness, flushing, headache and taste alteration occur exclusively with pulse therapy.

Sixteen control subjects and 15 subjects with type 2 diabetes were examined to compare gait characteristics during walking in a linear path and in turns of 0.33 and 0.66 m diameter. Subjects were excluded if there was diminished sensation in the feet or impairment of strength in the legs. This was done to isolate the effect of diabetes gait independent of loss of sensation. Gait was assessed through contact sensors on the foot, video, and two axis accelerometers mounted bilaterally on the head, shoulders, hips, knees and ankles. The results of these experiments showed that subjects with diabetes walked significantly slower (P<0.05) than control subjects and with a wider stance (P<0.01), both for walking in a linear path (velocity of subjects with diabetes was 62.2% that of controls and stance was 134.9% wider than controls) and when making turns (velocity 50.6% of controls and stance 120.1% wider than that of controls). Accelerometry showed increased flexion/extension and lateral movement of the major joints in subjects with diabetes during both walking in a linear path and turns compared to control subjects. Part of the increased movement at the joints in the subjects with diabetes was due to tremor in both the 8 Hz and 16 Hz bands. These findings suggest that at least some of the increased joint movement during walking in people with diabetes is likely neurological in origin and not related to muscle weakness or loss of sensation in the feet.

A case manifesting symptoms due to organochlorine toxicity was treated with the fat substitute olestra in his diet. Before treatment, the patient was obese, with severe type 2 diabetes mellitus and mixed hyperlipidemia, chloracne, frequent headaches, and numbness and paraesthesias of his trunk and lower limbs. Earlier attempts at weight loss had been unsuccessful due to worsening of his symptoms. After inclusion of olestra in his diet for 2 years, weight loss was successful without aggravation of his symptoms, and the patient reverted to normoglycemia and normolipidemia. Olestra may have assisted weight loss and amelioration of his diabetes by increasing fecal elimination of organochlorines, rather than by preventing the partitioning of these pollutants into tissues, where they have been reported to exert antimetabolic effects on substrate oxidation.
