Abstract

Background

Bacterial infections in cirrhotic patients remain a challenge. Presepsin has been proposed as a valuable sepsis biomarker. We aimed to assess plasma presepsin levels in uncomplicated cirrhotic patients and to correlate them with liver disease severity and complicating events, defined as documented bacterial infection with or without concomitant portal hypertension-related bleeding, or bleeding without documented bacterial infection, with or without acute kidney injury.

Methods

We prospectively evaluated the presepsin levels of 108 consecutive uncomplicated cirrhotic patients with compensated (55, 50.9%) or decompensated (53, 49.1%) cirrhosis. During the follow up, 20 patients were reevaluated for a complicating event.

Results

Mean baseline presepsin levels of the entire population were 440.4 pg/mL. Patients with decompensated cirrhosis exhibited significantly higher baseline levels than patients with compensated cirrhosis (599.1±492.2 vs. 287.5±130.5 pg/mL, P<0.001). In complicated cirrhotic patients, admission levels were remarkably higher than baseline (1438.0±1247.2 vs. 725.3±602.8 pg/mL, P<0.001), especially in those who developed acute kidney injury compared to those who did not (1827.3±1118.8 vs. 1048.7±1302.1 pg/mL, P<0.05). Baseline presepsin levels, using a cutoff of 607.5 pg/mL, could predict liver disease-related 3-month mortality with 77.8% sensitivity and 86.9% specificity: area under the receiver operating characteristic curve 0.825; 95% confidence interval 0.684-0.967; P<0.01.

Conclusions

Plasma presepsin levels are elevated in uncomplicated cirrhotic patients, especially in those with advanced liver disease, and rise further in those complicated by an event. Baseline presepsin levels in cirrhotic patients could be used as an additional marker, along with the model for end-stage liver disease score, to predict short-term outcomes.

Abstract

Three methods of esophagoscopy are available until now: sedated conventional endoscopy, unsedated ultrathin endoscopy, and esophageal capsule endoscopy. The three methods carry comparable diagnostic accuracy and different complication rates. Although all of them have been found well accepted from patients, no comparative study comprising the three techniques has been published. The aim of this study was to compare the three methods of esophagoscopy regarding tolerability, satisfaction, and acceptance. Twenty patients with large esophageal varices and 10 with gastroesophageal reflux disease were prospectively included. All patients underwent consecutively sedated conventional endoscopy, unsedated ultrathin endoscopy, and esophageal capsule endoscopy. After each procedure, patients completed a seven-item questionnaire. The total positive attitude of patients toward all methods was high. However, statistical analysis revealed the following differences in favor of esophageal capsule endoscopy: (i) total positive attitude has been found higher (chi(2)= 18.2, df = 2, P= 0.00), (ii) less patients felt pain (chi(2)= 6.9, df = 2, P= 0.03) and discomfort (chi(2)= 22.1, df = 2, P= 0.00), (iii) less patients experienced difficulty (chi(2)= 13.7, df = 2, P= 0.01), and (iv) more patients were willing to undergo esophageal capsule endoscopy in the future (chi(2)= 12.1, df = 2, P= 0.002). Esophageal capsule endoscopy was characterized by a more positive general attitude and caused less pain and discomfort. Sedated conventional endoscopy has been found more difficult. More patients would repeat esophageal capsule endoscopy in the future. Patients' total position for all three available techniques for esophageal endoscopy was excellent and renders the observed advantage of esophageal capsule endoscopy over both sedated conventional and unsedated ultrathin endoscopy a statistical finding without a real clinical benefit.

Abstract

BACKGROUND AND AIMS

Diabetes mellitus is implicated in several liver diseases; hence, its potential affection to liver regenerative capacity is an open research question. So far, only sporadic studies have addressed this issue, mainly using basic statistical techniques. The current study evaluated the ability of a novel technique, namely higher-order crossings (HOC), based on liver DNA biosynthesis and thymidine kinase (TK) enzymatic activity data, to discriminate liver regeneration processes between hepatectomized diabetic and non-diabetic rats.

METHODS

We used 251 adult male rats, divided in two groups; diabetic by Alloxan injection and non-diabetic control, subjected to 70% partial hepatectomy and killed at different time intervals post-partial hepatectomy (PH) (0-240 h). The rate of tritiated thymidine (3HTdR) incorporation into hepatic DNA and the enzymatic activity of liver TK were estimated and, after proper interpolation, were analyzed using HOC sequences. Changes of the latter were captured and used as a means for linear discrimination between the two groups.

RESULTS

Ninth-order HOC estimated for post-PH (24, 28, 40, 44, 72 and 84 h) exhibited linear discrimination for the rate of 3HTdR incorporation, whereas second-order HOC estimated for (44-72 h) post-PH exhibited linear discrimination for the TK enzymatic activity data. Fuzzy logic-based c-means cluster analysis of HOC provided distinct areas of group categorization (100% accuracy) for diagnostic distinctions (P < 0.001). The data grouping pointed out by the HOC-based analysis revealed an onset delay in the liver regeneration process when Alloxan diabetes was present (P < 0.05).

CONCLUSIONS

Our results suggest that HOC have the potential to linearly discriminate between experimentally induced diabetic and non-diabetic liver regeneration post-PH processes, based on two liver regeneration indices, capturing the delay seen in the liver regeneration process due to Alloxan diabetes, fostering their use as an efficient classification tool. In this way, HOC could be used as an advanced, easily implemented and user-friendly method to thoroughly analyze liver regeneration processes.

Abstract OBJECTIVES:To evaluate the predictive value of serum beta2-microglobulin (β2m) levels for virological breakthrough in hepatitis B e antigen-negative chronic hepatitis B patients under long term lamivudine monotherapy.METHODS:Serum β2m levels were calculated at baseline and every three months during lamivudine monotherapy in 25 patients with chronic hepatitis B, using microparticle enzyme immunoassay technology to investigate their association with biochemical, virological and histological outcome data. Cox proportional hazard models were used to investigate the association between serum β2m levels and virological breakthrough.RESULTS:Seven of 25 (28%), nine of 25 (36%) and 14 of 25 (56%) chronic hepatitis B patients exhibited virological breakthrough at months 12, 24 and 36 of treatment, respectively. All chronic hepatitis B patients who did not show virological breakthrough in the follow-up period exhibited β2m elevation in month 3 of treatment. The duration (in months) of serum β2m elevation was significantly higher in the responders group than the nonresponders group (7.3±2.6 versus 3.8±3.4, P=0.02). In contrast to patients whose serum β2m levels were increased at three months, patients whose β2m levels were decreased had a 4.6 times higher risk of experiencing virological breakthrough (hazards ratio 4.6, 95% CI 1.22 to 17.36). When age, pretreatment serum alanine aminotransferase and hepatitis B virus DNA levels, and grade of liver disease were simultaneously included in the same Cox model, decreased β2m status was still associated with increased risk of virological breakthrough (hazards ratio 12.2, 95% CI 1.28 to 116.8).CONCLUSIONS:In hepatitis B e antigen-negative chronic hepatitis B patients under long term lamivudine monotherapy, serum β2m levels at three months of treatment, compared with baseline levels, are good predictors of risk for virological breakthrough.

Abstract

OBJECTIVE

Lamivudine is a nucleoside analogue with potent antiviral activity against hepatitis B virus (HBV). Plasma pituitary adenylate cyclase activating polypeptide (PACAP) is a multifunctional neuropeptide that is produced within the lymphoid microenvironment and induces the production of Th2-type cytokines. The aim of our study was to investigate the possible alterations of plasma PACAP-38 levels in chronic hepatitis B (CHB) patients during lamivudine treatment and to compare them with biochemical, virological and histological data.

METHODS

Plasma PACAP-38 levels were measured using competitive radio-immune analysis (RIA) in 25 CHB patients before and after completion of a 52-week lamivudine treatment period and in 22 healthy blood donors. Biochemical evaluation was done at baseline and every three months during treatment. Virological evaluation (HBV-DNA) was performed at baseline and at weeks 24 and 52 of treatment. Baseline liver histology was assessed for all patients at the beginning and at week 52 of the study for histological comparison with the pretreatment biopsy, according to the Ishak scoring system. Statistical evaluation of data was done using analysis of variance and Student's t-test.

RESULTS

Virological breakthrough was observed in seven (28%) patients at week 52 of treatment. Histological improvement was observed in 21 (84%) CHB patients, despite the emergence of tyrosine-methionine-aspartate-aspartate (YMDD) mutations. Plasma PACAP-38 levels were significantly lower in CHB patients at baseline than in healthy blood donors. Significant elevation of plasma peptide levels was observed in CHB patients after the completion of lamivudine treatment period, even in the subgroup of those who exhibited YMDD variants.

CONCLUSION

The elevation of plasma PACAP-38 levels in treated CHB patients following lamivudine-induced elimination of viraemia suggests a possible alteration of T-cellular immune response, resulting in biochemical and histological remission of liver disease, even in patients who exhibited virological breakthrough.
