Special Issue Information
Dear Colleagues,
Type 2 diabetes is characterized by a high level of morbidity and mortality. Although there is a trend toward better survival among diabetic and non-diabetic patients, a relevant residual risk is still present among those with diabetes. Therefore, an early diagnosis of diabetes is essential. CGMS, as well as the evaluation of a high quantity of blood glucose data, might help in obtaining an earlier and better diagnosis of carbohydrate disturbances.
Microvascular complications usually precede microvascular complications; both survival and quality of life are related to vascular complications. This way, early and more precise diagnosis of microvascular and macrovascular complications is essential for improving the survival of our patients. Among microvascular complications, neuropathy is of particular importance, which is a complication of diabetes with a poor prognosis. This condition develops over time in more than half of diabetic patients. It is now clear that the prevention of microvascular complications such as neuropathy, near-normoglycemia, close metabolic control, and the management of other risk factors like hypertension, obesity, and hyperlipidemia are also very important. There are two main mechanisms involved in the development of neuropathy: functional and/or structural damage to the vasa nervorum, and the direct effect of hyperglycemia on neurons. The pathogenetic significance of the metabolic pathway is under continuous investigation. Hyperglycemia leads to an increase in the amount of glucose entering nerve cells, which is compensated by the hexokinase capacity for a period of time. However, at the limit of maximum capacity, the alternative metabolic pathways, e.g., the sorbitol and hexosamine pathways, as well as the mechanisms leading to protein kinase C activation and enhanced end-glycation product (AGE) formation, are amplified. In some trials on diabetic patients, intensive metabolic control reduced the progression of diabetic neuropathy without being completely preventable. Progressing neuropathy may occur with a persistently favorable metabolic status in some patients with diabetes mellitus, while in others, though seldom, persistently unfavorable metabolic status is not associated with significant neuropathy. This may be mainly due to genetic differences. Furthermore, the impact of COVID-19 on diabetes and its complications is still uncertain and needs to be defined.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metabolites is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).
