Background

Voglibose, an α-glucosidase inhibitor, inhibits breakdown of complex carbohydrates into simple sugar units in intestine. Studies showed that voglibose metabolism in the liver might be negligible due to its poor intestinal absorption. Numerous microorganisms live in intestine and have several roles in metabolism and detoxification of various xenobiotics. Due to the limited information, the possible metabolism of voglibose by intestinal microbiota was investigated in vitro and in vivo.

Methods

For the in vitro study, different concentrations of voglibose were incubated with intestinal contents, prepared from both vehicle- and antibiotics-treated mice, to determine the decreased amount of voglibose over time by using liquid chromatography-mass spectrometry. Similarly, in vivo pharmacodynamic effect of voglibose was determined following the administration of voglibose and starch in vehicle- and antibiotic-pretreated non-diabetic and diabetic mice, by measuring the modulatory effects of voglibose on blood glucose levels.

Results

The in vitro results indicated that the remaining voglibose could be significantly decreased when incubated with the intestinal contents from normal mice compared to those from antibiotic-treated mice, which had less enzyme activities. The in vivo results showed that the antibiotic pretreatment resulted in reduced metabolism of voglibose. This significantly lowered blood glucose levels in antibiotic-pretreated mice compared to the control animals.

Conclusion

The present results indicate that voglibose would be metabolized by the intestinal microbiota, and that this metabolism might be pharmacodynamically critical in lowering blood glucose levels in mice.

AbstractAbstract PDFPubReader   

The metabolic syndrome refers to a well defined group of risk factors, including central obesity and inflammation, for the development of diabetes and cardiovascular disease. Interestingly, many studies have recently led to the emergence of somewhat unexpected relationships between several infectious diseases and various aspects of the metabolic syndrome. Our understanding of the mechanisms underlying these interactions is also rapidly developing and some of these are summarized in this article. We will focus first on bacterial infection, and most notably the role of gut microbiota in regulaton of both obesity and inflammation. In particular, we focus on the role of inflammasomes and propose that understanding the role of Toll-like receptors and Nod-like receptors in the pathogenesis of inflammatory disorders with or without infection may provide novel targets for prevention and/or treatment of associated diseases. Secondly, chronic bacterial or viral infection and emerging links with metabolism will be reviewed. Finally, consideratons of biomarkers for metabolic syndrome, in particular lipocalin-2, and their link with infection will be discussed.

AbstractAbstract PDF
Acute multifocal bacterial nephritis is a severe form of acute renal infection in which a heavy leukocytic infiltrate occurs throughout the kidney. It is also an early phase of renal corticomedullary abscess. Clinically, patients have evidence of a severe urinary tract infection secondary to a gram-negative organism and there are frequently signs of sepsis. About half of the reported patients have been diabetics. Urinary tract infections are more common in diabetic women than in non-diabetic women. A variety of factors may contribute. The most important predisposing factor may be bladder dysfunction as a result of diabetic neuropathy and cystopathy. Diabetic cystopathy begins as decreased bladder sensation and decreased reflex detrusor activity caused by neuropathy affecting sympathetic and parasympathetic afferent fibers. Impaired bladder sensation results in bladder distention and increased residual urine volume. Long-term effects may eventually be vesicoureteral reflux and recurrent upper urinary tract infection. However, until now no diabetic patient with acute multifocal bacterial nephritis has been reported in Korea. Acute multifocal bacterial nephritis can be diagnosed by clinical manifestations and on radiologic grounds, including abdominal computed tomography showing multiple, wedge shaped, poorly defined areas of decreased contrast enhancement in multiple renal lobes. Therefore, we report the first Korean case of acute multifocal bacterial nephritis associated with diabetic autonomic neuropathy and review the literatures.
