Diabetes mellitus is a chronic disease associated with a series of long-term microvascular and macrovascular complications that requires continuing therapeutic control. In recent years, the pharmaceutical industry has developed new types of insulin and administration systems in order to more closely mimic human insulin secretion. ⋯ In type 2 diabetes mellitus, we can start with a simplified conventional regimen which could progress into an intensive one similar to that of T1DM treatment. Both types of diabetes require an individualized treatment prescription based on the needs and characteristics of each patient.

The participation of genetic and environmental factors has always been invoked in the pathogenesis of the autoimmune systemic diseases, including the primary vasculitides. Among the environmental factors, infections, fundamentally those having a viral nature, have always been focused on, especially after the discovery of the close existing relationship between the polyarteritis nodosa and the hepatitis B virus, on the one hand, and mixed cryoglobulinemia and the hepatitis C virus, on the other. The present review summarizes data from the most recent literature related to associations between virus infections and primary vasculitides, following the Chapel-Hill vasculitis classification.

In this article we briefly review the evidence on the effect of different "natural" products on cholesterolemia. Plant stanols and sterols reduce cholesterol intestinal absorption and decrease total and LDL cholesterol by approximately 10%. Polycosanol is a mixture of saturated alcohols that seem to inhibit cholesterol hepatic synthesis and decrease total and LDL cholesterol by up to 25%. The effects on the cholestorolemia of soy and soluble fiber are modest.

Review[ARB II in chronic heart failure. Coincidences and divergences. Class effect?].
Although it is possible to suggest that the ACE inhibitor may have a certain class effect in regards to the benefits observed in the treatment of chronic heart failure, it does not seem reasonable that the same can be assumed in the case of ARB II. Morbidity-mortality studies in chronic heart failure have only been conducted with three of the seven ARB II presently commercialized in our country. ⋯ In these clinical comments, we review the evidence available, stressing what effects could be common to all the ARB II, such as the prevention of diabetes or atrial fibrillation and what effects may only be attributable to some of these, at least up to now. However, new information of the already finished studies and some still on-going clinical trials may help us to know the effects of the ARB II in this disease more and better.

In this review the current situation of gene therapy is described in hematological diseases, immunological conditions, and cancer. In all of them, the principal objective of various approaches with gene therapy is transduction of therapeutic genes in most of target cells. ⋯ Consequently, vectors are one of the basic elements to optimize gene therapy approaches and protocols in view of the facts that we know that with liposomes less than 10% of cells are transduced, that retrovirus only infect cells in replication, and that adenovirus give rise to an important inflammatory response and a transitory transduction of the therapeutic gene. In addition recent approaches in cancer gene therapy with selective replication virus, suicidal genes, etc., are discussed.
