Indolylacryloylglycine (IAcrGly) is one of the physiological components of urine, although its source and its role in the human organism have not yet been unambiguously established. Changes in the IAcrGly excretion level have been found under some physiological (age dependence, seasonal variations) and pathological (photodermatoses, muscle dystrophy, liver cirrhosis) conditions. The proposed method for IAcrGly, indolylacrylic acid and its possible precursors, namely indolyllactic and indolylpropionic acids, involves deproteinization and extraction of urine on a Sep Pak C18 cartridge. HPLC analysis was carried out using a DataApex liquid chromatograph, equipped with an LCD 2082 UV detector, signals being acquired with a CSW workstation. The chromatographic column was Spherisorb ODS, 5 microns (125 x 4 mm I.D.), the mobile phase for isocratic elution was ethanol-1% acetic acid (27:73) and the flow-rate was 0.7 ml/min. The lower response limit is about 1 mumol/l for all metabolites at 280 nm.

There is controversy among pathologists when assessing the presence or absence of liver cell dysplasia in liver biopsies taken from cirrhotic patients. The objective of the present study was to determine the DNA ploidy pattern of hepatocytes of patients with liver cirrhosis and its relationship to liver cell dysplasia. A total of 48 male patients diagnosed with liver cirrhosis based on clinical, laboratory and histopathological criteria were included in the study. A liver biopsy was taken from each patient; one part of the biopsy was subjected to histopathology, and the other to flow cytometry. The histopathological examination revealed liver cell dysplasia in 60% of patients with liver cirrhosis (62% of them had large cell dysplasia [LCD] and 38% had small cell dysplasia [SCD]). Abnormal DNA content (aneuploidy) was found in 81.5% of positive liver cell dysplasia specimens and found only in 11.1% of negative liver cell dysplasia specimens, with a statistically significant difference (P<0.001). Aneuploidy was found more commonly in LCD but without significant difference (P>0.05) in comparison with SCD. In conclusion, SCD (similar to LCD) is also associated with aneuploidy and elevated DNA index, and may carry the same risk for progression to hepatocellular carcinoma.

Pharmacokinetics of sildenafil and its metabolite, N-desmethylsildenafil, in humans and rats with liver cirrhosis (LC) and diabetes mellitus (DM), alone and in combination (LCD) did not seem to be reported. Sildenafil was administered intravenously (10 mg/kg) and orally (20 mg/kg) to control, LC, DM, and LCD rats. Expression of intestinal CYP isozymes in those rats was also measured. In LC, DM, and LCD rats, the areas under the curve (AUCs) of intravenous sildenafil were significantly greater (by 195%, 54.2%, and 127%, respectively) than controls. In LC and LCD rats, AUCs of oral sildenafil were significantly greater (3010% and 2030%, respectively) than controls. In LC, DM, and LCD rats, significantly greater AUCs of intravenous sildenafil were due to the slower hepatic extraction of sildenafil (because of decrease in the protein expression of hepatic CYP2C11 and 3A subfamily in LC and LCD rats, and CYP2C11 in DM rats). In LC and LCD rats, greater magnitude of increase in AUCs of oral sildenafil than those after the intravenous administration could be mainly due to the decrease in the intestinal extraction of sildenafil (because of decrease in the protein expression of intestinal CYP2C11 in LC and LCD rats).

Both type 2 diabetes (T2D) and chronic hepatitis C (CHC) infection are associated with increased risk of developing hepatocellular carcinoma (HCC). Cytokines are known to play an important role not only in the mechanisms of insulin resistance and glucose disposal defects but also in the pathological processes occurring in the liver during viral infection. We evaluated the serum levels of many cytokines, chemokines, adipokines and growth factors in patients with type 2 diabetes, CHC, CHC-related cirrhosis, CHC and type 2 diabetes and CHC-related cirrhosis and type 2 diabetes by BioPlex assay. The obtained data evidenced that the serum levels of some proteins are significantly up-regulated in all the patients or in those with only one disease and are often higher, even if in different amounts, when both diseases are associated. In particular, our results can be useful for the clinical monitoring of patients because they give specific information in regard to the progression from CHC to LC and CHD to LCD. Moreover, some molecules have shown significant correlations with clinical/biochemical data, suggesting the possibility to define mini-panels that can be used as specific markers for the different disease staging. However, our observations demonstrate that an integrated approach is much more powerful than isolated measurements to evaluate specific stages of these two complex pathologies (type 2 diabetes and chronic CHC hepatitis) alone or when they are concomitant in a patient. In fact it has emerged as an accurate, simple, specific, noninvasive, reproducible and less expensive method that, in future, could be included in routine clinical practice to monitor the association of type 2 diabetes and/or CHC to liver cirrhosis and, possibly, to cancer, and to improve the prognosis of these diseases.
