Iloprost, a stable prostacyclin analog, was evaluated clinically for its ability to ameliorate the symptoms of peripheral neuropathy associated with diabetes. In an open, nonrandomized trial, 13 diabetic patients with neuropathy but without proliferative retinopathy received an intravenous infusion of Iloprost at a dose of 10 micrograms, at a rate of 0.1 micrograms/kg/h, twice daily for two weeks. The administration of Iloprost relieved the majority of such subjective symptoms as pain, numbness or sensation of cold and to a lesser extent, such autonomic symptoms as dizziness. In contrast, there was little evidence of objective improvement, e.g., in motor nerve conduction velocity. Iloprost treatment significantly inhibited the platelet aggregation rate stimulated by collagen in vitro. In the one patient tested, thermography revealed an increase in skin temperature by more than 2 degrees C. Side effects associated with Iloprost included headache (3 patients) or aggravation of pain in the extremities (2 patients) and could be ameliorated by slowing the infusion rate or by discontinuing the drug (one patient). Iloprost appears to be safe and effective for relieving the symptoms of diabetic neuropathy. Our results provide the rationale for a double-blind, clinical trial in larger populations of diabetics with peripheral neuropathy.

A 19-year-old woman with insulin-dependent diabetes mellitus (IDDM) of 3.5 years duration had been suffering from recurrent episodes of diabetic ketoacidosis (DKA), dizziness, and weight loss (16 kg, 29%) for 6 months. History and physical examination gave evidence of severe peripheral and autonomic neuropathy. Radionuclide retention on gastric emptying test at 60 min was greater than 90% (normal < 60%). On autonomic cardiovascular testing there was evidence of both parasympathetic and sympathetic damage. There was no evidence of nephropathy or retinopathy. Optimal diabetic control using 4 insulin injections (2 u/kg/day) and high-dose cisapride terminated the vomiting, and she regained the weight lost within 5 months. This case is unique in that severe diabetic neuropathy followed relatively soon after onset of disease, without other microvascular complications. The correct diagnosis of gastroparesis as the cause of the recurrent DKA and weight loss, and the specific prokinetic therapy and nearly normoglycemic control of the diabetes led to dramatic clinical and functional improvement. Specific prokinetic therapy and the nearly normoglycemic control of the diabetes led to dramatic clinical and functional improvement. Gastroparesis can cause recurrent DKA even in young patients with IDDM of short duration.

Epalrestat is a carboxylic acid derivative which inhibits aldose reductase, an enzyme of the sorbitol (polyol) pathway. Under hyperglycaemic conditions epalrestat reduces intracellular sorbitol accumulation, which has been implicated in the pathogenesis of late-onset complications of diabetes mellitus. Epalrestat 150 mg/day for 12 weeks improved motor and sensory nerve conduction velocity, and vibration threshold compared with baseline and placebo in patients with diabetic neuropathy. Subjective symptoms including pain, numbness, hyperaesthesia, coldness in the extremities, muscular weakness, dizziness, and orthostatic fainting were also improved. Similar benefits were seen in a comparison with historical controls. Epalrestat 300 mg/day for 1 or 3 years was also significantly superior to placebo or no treatment in improving electroretinogram parameters and photo stress recovery time in patients with diabetic retinopathy. Improvements were also documented by funduscopy and fluorescein angiography. Epalrestat appeared most effective in patients with less severe diabetes mellitus and more recent development of late-onset complications. Epalrestat is apparently well tolerated with predominantly minor adverse events reported in clinical trials. Liver enzyme elevations were most commonly reported but generally resolved spontaneously on dose reduction or discontinuation. The effects of age and renal impairment on the efficacy and tolerability of epalrestat require clarification, and data on its use in other late-onset complications of diabetes such as nephropathy are also lacking. Comparisons with other aldose reductase inhibitors are also required to fully determine the role of epalrestat. The suggested ability of epalrestat to prevent the onset of diabetic complications should also be investigated. Thus, available data suggest epalrestat produces some improvement in the late-onset neuropathy and retinopathy associated with diabetes mellitus, although additional trials are required to determine whether ongoing therapy is necessary to maintain the improvements achieved and to confirm tolerability in the long term. Nevertheless, preliminary results suggest that epalrestat may be a useful drug in an area where there is a need for effective therapy.

Thirty-one adult diabetic patients with painful distal symmetrical polyneuropathy were treated with low doses of oral trazodone (50 or 100 mg/day). After 2 weeks of therapy, 19 patients (61.3%) experienced symptomatic relief, and 7 (22.6%) experienced complete relief. Although 8 patients (25.8%) discontinued the drug because of side effects, these were relatively minor (dizziness, headache, insomnia). Low-dose trazodone is recommended as an effective treatment option for painful diabetic neuropathy.

Gabapentin, which has been approved for add-on therapy of focal seizures, is increasingly used for treatment of neuropathic pain. Its analgesic effect is supposed to be due to reduction of glutamatergic transmission, improvement of GABAergic transmission and to binding to voltage-dependent calcium channels. Experimental studies demonstrated an ameliorating effect of gabapentin on neuropathic pain. Placebo-controlled studies revealed an efficacy of gabapentin against pain in diabetic neuropathy and postherpetic neuralgia and in prophylaxis of migraine. Case reports show an analgesic effect of gabapentin in trigeminus neuralgia and in reflex sympathetic dystrophy. The main adverse events are dizziness, ataxia and somnolence. Controlled studies, which compare the efficacy of gabapentin with that of the respective reference drug, are needed to evaluate its importance in treatment of pain.

Diabetic neuropathy encompasses various disturbances concerning somatic and autonomic nervous system and has significant impact on prognosis and course of diabetes mellitus. The aim of the work is an evaluation of vestibulo-spinal reflexes in children and young adults suffering from diabetes mellitus type 1. Material--95 children and young adults aged from 6 to 28 years with diabetes mellitus type 1 diagnosed. The control group consisted of 44 otoneurologically healthy subjects aged from 6 to 28 years. After detailed medical history collection and physical ENT examination stato-posturography was performed in each case. Posturographer PE 62 Model 04 was applied in the studies. Static posturography as well as dynamic one (one leg standing test) was performed in each case. 6 patients belonging to diabetic group complained about vertigo or dizziness. There were worse stabilograms parameters in diabetic group in comparison to control one, statistically significant in younger children. There were better stabilogram parameters in diabetic patients with longer history of the disease. The parameters analysed were significantly worse in the subgroup with not compensated diabetes. The parameters were slightly better in relation to the presence of hypoglycaemic incidents. No apparent differences in stabilograms parameters were present in relation to the presence of diabetic complications. Diabetes mellitus type 1 with slight or without complications does not have significant influence on vestibulo-spinal reflexes and posture stability of the patients. Balance organ disturbances in diabetes mellitus type 1 in children and young adults despite their presence have subclinical course. Perhaps one should consider monitoring of those disturbances in the course of the disease.

Neuropathic pain is a syndrome that affects around 1% of population. This condition can be severely disabling and traditional analgesics are useless against this type of pain. Several adjuvants such as the anticonvulsive agent gabapentin have been used to treat diabetic neuropathy with several degrees of effectiveness, but it is characterized of a high incidence of dizziness, somnolence and ataxia. Previously we have found a functional synergistic interaction after co-administration of gabapentin and B vitamins by using a neuropathic pain model in the rat. In order to evaluate the efficacy of gabapentin and B vitamins in the treatment of diabetic neuropathy in humans we carried out a comparative trial. In this study are presented preliminary results from 6 patients assigned to two groups: group A (n=3) received gabapentin, and group B (n=3) received gabapentin plus B vitamins. In both groups, the dose was increased at weekly intervals, and characteristics of pain and some parameters of quality of life were assessed. Both treatments significantly reduced pain and improved quality of life in the patients. Dizziness was the main adverse event observed in both groups. Data suggest that the combination of gabapentin and B vitamins could be an alternative treatment for diabetic neuropathic patients.

Pregabalin is increasingly being used for the treatment ofneuropathic pain, often as the first-line choice. The question is, however, whether this choice is based on evidence. Seven trials have been published on the effect ofpregabalin in patients with postherpetic neuralgia and painful diabetic neuropathy. These trials more frequently report a 50% reduction in pain in pregabalin treated patients than in patients treated with placebo (number needed to treat 4.3). Dizziness and somnolence are the most frequent adverse events of pregabalin. The number needed to harm for adverse events leading to discontinuation of treatment varies from 3.7 to 113.1 in these studies. Pregabalin has not been compared head-to-head with other drugs commonly used for neuropathic pain. Indirect comparison reveals the effectiveness of pregabalin is comparable with that of carbamazepin, tramadol, and gabapentin; pregabalin is possibly less effective than amitriptylin. However, taking into account its price and the lack of clinical experience and evidence, using pregabalin as first-line choice is not recommended.

Carisbamate is a novel drug with neuromodulator activity that is currently under development for the treatment of epilepsy, diabetic neuropathy and neuralgia. The compound possessed a promising pharmacological profile in tests in vivo, and demonstrated broad anticonvulsant activity in preclinical studies, both elevating seizure threshold and preventing seizure spread. Carisbamate was also effective in protecting against spontaneous recurrent seizures in kainate-treated animals and in genetic models of epilepsy, and displayed antiepileptic and neuroprotective activity in the lithium-pilocarpine model of status epilepticus. In a phase I clinical trial, orally administered carisbamate demonstrated efficacy at high doses of 500 to 1000 mg. A phase II clinical trial confirmed that oral carisbamate was efficacious at a 300- to 1600-mg dose range. The preliminary evaluations of carisbamate in humans indicated complete absorption, extensive metabolism, and carbamate ester hydrolysis. The most frequently reported side effects associated with carisbamate are dizziness, headache, somnolence and nausea. In clinical trials, carisbamate did not display any significant interactions with commonly used antiepileptic drugs such as carbamazepine, valproate and lamotrigine. At the time of publication, a phase III clinical trial for carisbamate in the treatment of epilepsy was ongoing, as well as phase II trials in neuropathy and neuralgia. Data from preclinical brain injury studies with carisbamate and the analog RWJ-333369-A have also been reported. This drug profile will focus on the development of carisbamate in epilepsy.
