The choice of an adequate treatment for neuropathic Diabetic neuropathies may impair quality of life, they are both prognostically and pathogenetically important pain should take into account proven efficacy, number and severity of adverse events, toxicity, pharmacofactors for the development of the diabetic foot syndrome and associated with a reduced life expectancy. kinetics, contraindications, limitations for treatment due to comorbid conditions, and—last not least—Improvement of metabolic control over the years has been proven to reduce the incidence of diabetic neuro-costs. Obviously, it is difficult to compare all these variables for the drugs to be described later, since there pathy in type 1 [1] and presumably also in type 2 diabetic patients [2, 3]. In the near future, besides is no common denominator for efficacy, and only in rare instances have different drugs been compared intensified diabetes treatment, metabolic steps important in the pathogenesis of diabetic neuropathy may be directly. A rough estimate of efficacy may be the number of patients needed to treat (NNT) to obtain targeted by specific drugs effectively inhibiting the accumulation of sorbitol, reducing oxidative stress, a substance specific beneficial effect in one patient [4]. Direct comparisons are, however, hampered by the stopping the formation of advanced glycation end products, improving nerve blood flow, reversing factthatNNT’sarederivedfromstudieswithdifferent durations of drug treatment and with different endpochanges in membrane lipid metabolism, or substituting nerve growth factors. At present, and in the forseeable ints which may not be directly comparable. The relevance of the NNT is further weakened by the fact that future, it seems to be impossible to completely eliminate the development of neuropathic diabetic lesions due to the small number of patients included in most studies, the 95% confidence intervals are sometimes because normoglycaemia is achieved in only a small part of all patients. This implicates that neuropathy extremely large. Consequently, the differences of NNT’s for different substances that have been found will remain a clinical problem for the years to come. Besides intensive treatment of diabetes which is indi-are frequently not statistically significant. Clearly, in clinical practice, the apparent response to a given drug cated in all patients at risk, additionally symptomatic treatment is necessary in some patients with neuro-is much better than indicated by the NNT, because not only specific but also unspecific effects including pathic pain. The prevalence of symptomatic distal symmetrical polyneuropathy, being the predominant placebo effects are observed [5]. cause of neuropathic pain in diabetic patients, ranges from 20 to 40%. The proportion of patients suffering from pain not treatable with simple analgesics and thus requiring specialized care is largely unknown. Physical measures Since diabetic micro-and macroangiopathic complications cluster in patients, it is the patient with diabetic As the first step in treating neuropathic pain it is useful nephropathy who is particularly in need of treatment to apply physical measures even though the effects of for neuropathic pain. application of creams, massage, and cold and warm applications are difficult to quantitate.
