Interim analysis of the PARADISE study: Benefits of add-on peginterferon-α in NA-treated patients with CHB.

This study aimed to investigate whether peginterferon-α (IFN) add-on nucleos(t)ide analogs(NAs) can further reduce hepatocellular carcinoma(HCC) risk compared with NAs monotherapy in NA-treated patients with chronic hepatitis B(CHB). In this multi-center randomized controlled trial "PARADISE study" (NCT05671315), CHB patients with intermediate to high risk of HCC after more than 24-week NAs pretreatment were recruited, randomized to two groups at a ratio of 1:2 and followed up for 240 weeks. NAs group maintained NAs monotherapy, while IFN + NAs group received IFN add-on NAs therapy for 48 weeks, then switched to NAs monotherapy. Totally, 196 patients were included in interim analysis (NAs group 68, IFN + NAs group 128). The 96-week cumulative HCC incidence was lower in IFN + NAs group than NAs group (0% vs. 4.5%, p < 0.05). Compared with NAs group, IFN + NAs group had significantly higher rates of HBsAg loss at week 48 and 96 (22.7% vs. 0%; 16.7% vs. 0%, both p < 0.05). A new scoring system was established to predict HBsAg decline >2log10 IU/ml, HBsAg <10 IU/ml or HBsAg loss at the end of 48-week IFN treatment. The area under ROC curve was 0.914, 0.922 or 0.905 in the original cohort (n = 128) and 0.896, 0.896 or 0.864 in the external validation cohort (n = 162) for the aforementioned three outcomes, respectively. IFN add-on NAs therapy may suggest the dual benefits of reducing HCC development and facilitating HBsAg loss among NA-treated CHB patients with intermediate to high risk of HCC. The new scoring system helps to make the most of IFN treatment for a higher cost-effectiveness in healthcare.

Farnesoid X receptor modulator 12ß-(m-methyl-benzoyl)-11,12-dihydro oleanolic acid represses liver fibrosis by inhibiting ERK/p38 signaling pathways.

Liver fibrosis is a common pathological process in the progression of several chronic liver diseases to cirrhosis and hepatocellular carcinoma. Therefore, the development of medications that can repress the progress of liver fibrosis is essential. We discovered that initially, 12ß-(m-methyl-benzoyl)-11,12-dihydro oleanolic acid (12d-OA), a farnesoid X receptor (FXR) modulator, possessed potential anti-fibrotic properties. Through an in-depth study, we revealed that 12d-OA not only inhibited the expression of fibrogenic markers in the LX-2 cells and HSC-T6 cells but also exhibited significant protective effects against liver injury and liver fibrosis in bile duct ligation (BDL) rats. Further exploration of its molecular mechanism indicated that 12d-OA exerted antifibrotic activity by inhibiting the extracellular signal-regulated kinase (ERK)/stress-activated protein kinase (p38) signaling pathways. Consequently, the great effects of 12d-OA in vitro and in vivo suggest that it may be a good candidate for liver fibrosis.

The Chinese Clinical Sleep Database: An Innovative Database System Includes Large-Scale Clinical Data of Chinese Population.

Purpose: In this study, we established the Chinese Clinical Sleep Database (CCSD), aiming to provide a safe, scalable, and user-friendly database that includes high-quality clinical data from Chinese population to facilitate sleep research. Material and Methods: We collect individual's demographic data, scales, anthropometric measurements, clinical diagnosis, and polysomnography (PSG) recordings from the routine medical process of sleep medicine centers using standardized procedures. The distributed cluster storage technology are utilized to store these data. The structured data are stored in a high-performance MySQL database, while the unstructured data are stored in an object storage service. And we have developed an online data platform to share and manage our data. Results: The data collection has been conducted in three hospitals. In the preliminary stage of data collection (from October 18, 2022 to September 4, 2023), our database included a total of 1183 patients. Among them, 56.8% were male and their ages ranged from 3 to 88 years. These patients were diagnosed with various types of sleep disorders. Conclusion: Since the CCSD's inception, it has demonstrated good stability, security, and scalability. As an public database, the CCSD also exhibits user-friendliness. The CCSD contains comprehensive clinical data, which can contribute to the advancement of the diagnosis and treatment strategies for sleep disorders, ultimately promoting sleep health.

Predictors of HBsAg seroclearance in patients with chronic HBV infection treated with pegylated interferon-α: a systematic review and meta-analysis.

BACKGROUND AND AIMS: The identification of reliable predictors for hepatitis B surface antigen (HBsAg) seroclearance remains controversial. We aimed to summarize potential predictors for HBsAg seroclearance by pegylated interferon-α (PegIFNα) in patients with chronic HBV infection. METHODS: A systematic search of the Cochrane Library, Embase, PubMed, and Web of Science databases was conducted from their inception to 28 September 2022. Meta-analyses were performed following the PRISMA statement. Predictors of HBsAg seroclearance were evaluated based on baseline characteristics and on-treatment indicators. RESULTS: This meta-analysis encompasses 27 studies, including a total of 7913 patients. The findings reveal several factors independently associated with HBsAg seroclearance induced by PegIFNα-based regimens. These factors include age (OR = 0.961), gender (male vs. female, OR = 0.537), genotype (A vs. B/D; OR = 7.472, OR = 10.738), treatment strategy (combination vs. monotherapy, OR = 2.126), baseline HBV DNA (OR = 0.414), baseline HBsAg (OR = 0.373), HBsAg levels at week 12 and 24 (OR = 0.384, OR = 0.294), HBsAg decline from baseline to week 12 and 24 (OR = 6.689, OR = 6.513), HBsAg decline from baseline ≥ 1 log10 IU/ml and ≥ 0.5 log10 IU/ml at week 12 (OR = 18.277; OR = 4.530), and ALT elevation at week 12 (OR = 3.622). Notably, subgroup analysis suggests no statistical association between HBsAg levels at week 12 and HBsAg seroclearance for treatment duration exceeding 48 weeks. The remaining results were consistent with the overall analysis. CONCLUSIONS: This is the first meta-analysis to identify predictors of HBsAg seroclearance with PegIFNα-based regimens, including baseline and on-treatment factors, which is valuable in developing a better integrated predictive model for HBsAg seroclearance to guide individualized treatment and achieve the highest cost-effectiveness of PegIFNα.

[Hepatotoxicity and mechanism of Rhododendri Mollis Flos based on zebrafish model].

This study used the zebrafish model to explore the hepatotoxicity of Rhododendri Mollis Flos(RMF). The mortality was calculated according to the number of the survival of zebrafish larvae 4 days after fertilization under different concentration of RMF, and the dose-toxicity curve was fitted to preliminarily evaluate the toxicity of RMF. The liver phenotypes under the sublethal concentration of RMF in the treatment group and the blank control group were observed by hematoxylin-eosin(HE) staining and acridine orange(AO) staining. Meanwhile, the activities of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were determined to confirm the hepatotoxicity of RMF. Real-time quantitative polymerase chain reaction(real-time PCR) and Western blot were used to determine the expressions of genes and proteins in zebrafish larvae. Gas chromatography time-of-flight mass spectrometry(GC-TOF-MS) was used to conduct untargeted metabolomics testing to explore the mechanism. The results showed that the toxicity of RMF to zebrafish larvae was dose-dependent, with 1 100 µg·mL~(-1) of the absolute lethal concentration and 448 µg·mL~(-1) of sublethal concentration. The hepatocyte apoptosis and degeneration appeared in the zebrafish larvae under the sublethal concentration of RMF. The content of ALT and AST in zebrafish larvae at the end of the experiment was significantly increased in a dose-dependent manner. Under the sublethal concentration, the expressions of genes and proteins related to apoptosis in zebrafish larvae were significantly increased as compared with the blank control group. The results of untargeted metabolomics showed that the important metabolites related to the he-patotoxicity of RMF were mainly enriched in alanine, aspartic acid, glutamic acid, and other pathways. In conclusion, it is inferred that RMF has certain hepatotoxicity to zebrafish larvae, and its mechanism may be related to apoptosis.

The interaction between polyphyllin I and SQLE protein induces hepatotoxicity through SREBP-2/HMGCR/SQLE/LSS pathway.

Polyphyllin I (PPI) and polyphyllin II (PII) are the main active substances in the Paris polyphylla. However, liver toxicity of these compounds has impeded their clinical application and the potential hepatotoxicity mechanisms remain to be elucidated. In this work, we found that PPI and PII exposure could induce significant hepatotoxicity in human liver cell line L-02 and zebrafish in a dose-dependent manner. The results of the proteomic analysis in L-02 cells and transcriptome in zebrafish indicated that the hepatotoxicity of PPI and PII was associated with the cholesterol biosynthetic pathway disorders, which were alleviated by the cholesterol biosynthesis inhibitor lovastatin. Additionally, 3-hydroxy-3-methy-lglutaryl CoA reductase (HMGCR) and squalene epoxidase (SQLE), the two rate-limiting enzymes in the cholesterol synthesis, selected as the potential targets, were confirmed by the molecular docking, the overexpression, and knockdown of HMGCR or SQLE with siRNA. Finally, the pull-down and surface plasmon resonance technology revealed that PPI could directly bind with SQLE but not with HMGCR. Collectively, these data demonstrated that PPI-induced hepatotoxicity resulted from the direct binding with SQLE protein and impaired the sterol-regulatory element binding protein 2/HMGCR/SQLE/lanosterol synthase pathways, thus disturbing the cholesterol biosynthesis pathway. The findings of this research can contribute to a better understanding of the key role of SQLE as a potential target in drug-induced hepatotoxicity and provide a therapeutic strategy for the prevention of drug toxic effects with similar structures in the future.

The potential effect of HBV vaccination on off-treatment HBsAg reversion after interferon-induced HBsAg clearance.

Off-treatment HBsAg reversion occurs in a considerable number of chronic hepatitis B(CHB) patients after IFN(interferon)-induced HBsAg clearance. HBV vaccination protects the general population against HBV infection. However, it remains unclear whether HBV vaccination could prevent off-treatment HBsAg reversion in CHB patients with HBsAg clearance. CHB patients (n = 199) with HBsAg clearance were included in the current study, comprising spontaneous HBsAg clearance group (n = 51), NA (nucleoside/nucleotide analogues)-induced group (n = 36) and IFN-induced group (n = 112). Log-rank test was performed to compare the cumulative incidences of HBsAg reversion between groups. Cox regression model was used to identify the factors associated with off-treatment HBsAg reversion. The 5-year cumulative incidence of HBsAg reversion in IFN-induced group was significantly higher than that in NA-induced group or spontaneous group (27.6% vs. 3.3% vs. 8.1%, both p < .05). In IFN-induced group, 66.7% of CHB patients received HBV vaccination. The cumulative incidence of HBsAg reversion in individuals with strong responses to HBV vaccination (HBsAb level >100mIU/ml) was significantly lower than that in those with weak responses to HBV vaccination (HBsAb level ≤100mIU/ml) or without HBV vaccination in IFN-induced group (7.7% vs. 58.5% vs. 31.9%, both p < .05). Multivariate Cox regression analysis confirmed strong responses to HBV vaccination were independently associated with a lower cumulative incidence of HBsAg reversion after IFN-induced HBsAg clearance (HR = 0.246, 95%CI: 0.066-0.907, p = .035). HBV vaccination has potential to prevent off-treatment HBsAg reversion in CHB patients after IFN-induced HBsAg clearance via a sufficiently high level of HBsAb, helping clinicians optimize the clinical management of such patients.

Carotid atherosclerosis: An independent risk factor for small fiber nerve dysfunction in patients with type 2 diabetes mellitus.

AIMS/INTRODUCTION: To explore whether carotid atherosclerosis is an independent risk factor for small fiber nerve dysfunction in type 2 diabetes mellitus patients. MATERIALS AND METHODS: A total of 247 type 2 diabetes patients from Nanjing Drum Tower Hospital received carotid ultrasonography and quantitative sensory testing, including cold and warm detection thresholds, and some patients received cold and heat pain detection thresholds, respectively. According to the results of quantitative sensory testing, patients were divided into normal small fiber nerve function (NSF) and small fiber nerve dysfunction (SFD) group. Meanwhile, patients were divided into the non-carotid atherosclerosis group, carotid intimal thickening, unilateral carotid atherosclerosis and bilateral carotid atherosclerosis group. The correlation between carotid ultrasonography with quantitative sensory testing parameters was analyzed by SPSS 26.0. RESULTS: First, the incidence rate of SFD increased significantly in patients with carotid atherosclerosis (72.2%, P < 0.001) especially in bilateral carotid atherosclerosis (81.7%, P < 0.001). Second, compared with the NS group, the carotid intima-media thickness in SFD was thicker (P = 0.018) and the size of atherosclerotic plaque was larger (P < 0.001). In addition, the cold detection threshold decreased (P < 0.001), whereas the warm detection threshold (P < 0.001) and heat pain detection threshold (P < 0.001) increased as aggravation of carotid atherosclerosis. In the correlation analysis, the size of atherosclerotic plaque presented a positive correlation with the warm detection threshold (r = 0.476, P < 0.001) and heat pain detection threshold (r = 0.213, P < 0.001), but presented a negative correlation with the cold detection threshold (r = -0.239, P < 0.01). Furthermore, carotid atherosclerosis (odds ratio 2.326, P = 0.017), especially bilateral carotid atherosclerosis (odds ratio 5.042, P = 0.001), was an independent risk factor for SFD (P < 0.05). CONCLUSIONS: Carotid atherosclerosis was significantly associated with quantitative sensory testing and found to be an independent risk factor for small fiber nerve dysfunction in type 2 diabetes patients.

Pseudogene SNRPFP1 derived long non-coding RNA facilitates hepatocellular carcinoma progress in vitro by sponging tumor-suppressive miR-126-5p.

Pseudogene-derived transcripts, especially those barely transcribed in normal tissues, have been regarded as a kind of non-coding RNAs, and present potential functions in tumorigenicity and tumor development in human beings. However, their exact effects on hepatocellular carcinoma (HCC) remain largely unknown. On basis of our previous research and the constructed online database for the non-coding RNAs related to HCC, a series of pseudogene transcripts have been discovered, and SNRPFP1, the homologous pseudogene of SNRPF, was found to produce an anomalously high expression long non-coding RNA in HCC. In this study, we validated the expression of the SNRPFP1 transcript in both HCC tissues and cell lines. The adverse correlation between SNRPFP1 expression and patients' outcomes was observed. And depletion of SNRPF1 in HCC cells significantly suppressed cell proliferation and apoptosis resistance. Meanwhile, the motility of HCC cells was potently impaired. Interestingly, miR-126-5p, one of the tumor-suppressive genes commonly decreased in HCC, was found negatively expressed and correlated with SNRPF1, and a specific region of SNRPF1 transcript is directly binding to miR-126-5p in a molecular sponge way. The rescue experiment by knock-out miR-126-5p significantly reversed the cell growth suppression and a higher ratio of cell apoptosis induced by SNRPF1 depletion. Lastly, we concluded that SNRPF1 is a pseudogene active in HCC, and its abnormally over-expressed transcript is a strong promoter of HCC cell progress in vitro by sponging miR-126-5p. We believe that the findings in this study provide new strategies for HCC prevention and therapeutic treatment.

Neuropathy scale score as an independent risk factor for myocardial infarction in patients with type 2 diabetes.

AIMS: To investigate whether peripheral neuropathy scale scores are associated with myocardial infarction (MI) in patients with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS: In this cross-sectional study, 32,463 T2DM patients were enroled from 103 tertiary hospitals in 25 Chinese provinces. Based on a history of MI, participants were divided into the MI group (n = 4170) and the non-MI group (n = 28,293). All patients were assessed using four neuropathy scales, namely, Neurological Symptom Score (NSS), Neurological Disability Score (NDS), Toronto Clinical Scoring System (TCSS), and Michigan Neuropathy Screening Instrument (MNSI), and some of the patients underwent evaluation of nerve conduction velocity (NCV) (n = 20,288). The relationship between these scores and myocardial infraction was analysed. RESULTS: The neuropathy scale scores in the MI group were higher than those in the non-MI group (p < 0.001). After dividing patients into four groups based on the grading criteria, our results showed that, in addition to aggravating the degree of neuropathy signs, the incidence of MI increased (p < 0.001). Logistic regression analysis results showed that neuropathy scale scores and NCV were both independent risk factors for MI (p < 0.001). Furthermore, among the scales used, MNSI presented a higher odds ratio and area under the curve (AUC; 0.625, p < 0.001) than the other three scales (AUCNSS  = 0.575, AUCNDS  = 0.606, and AUCTCSS  = 0.602, p < 0.001) for MI. CONCLUSIONS: Increased scores on these neuropathy scales (NSS, NDS, TCSS, and MNSI) and NCV were significantly associated with increased risk of MI and were considered independent risk factors.

qHBsAg for the Identification of Liver Histological Abnormalities in HBeAg-Negative Chronic Hepatitis B Patients with Normal and Mildly Elevated ALT Levels.

Backgrounds: Noninvasive detection of histological abnormalities remains challenging in patients with HBeAg-negative chronic HBV infection with normal or mildly elevated levels of alanine aminotransferase (ALT). This study aimed to assess the utility of serum quantitative hepatitis B surface antigen (qHBsAg) in identifying significant histological lesions in this population. Methods: This is a single-center study with retrospective analysis of 392 treatment-naive patients of HBeAg-negative chronic HBV infection with normal or mildly elevated levels of ALT. Results: In this cohort, significant necroinflammation and fibrosis were found in 69.4% and 61.5% of patients, respectively. Patients with qHBsAg >1000 IU/mL (N = 236) had more hepatic inflammation of ≥G2 (75.4% vs. 60.9%, P < 0.01) or fibrosis ≥ S2 (66.1% vs. 54.5%, P < 0.05) compared to those without (N = 156). Serum HBsAg (cutoff point = 1000 IU/mL), aspartate aminotransferase (AST) level (cutoff point = 25 IU/L), age (cutoff point = 40 years), and HBV family history were identified as independent predictors of significant histological abnormalities in multivariate logistic analysis. Conclusions: A significantly higher proportion of patients with histological abnormalities were found in patients with qHBsAg >1000 IU/mL than those without. The qHBsAg level together with age, AST, and family history of HBV infection could be used as an algorithm to help noninvasive patient selection for antiviral therapy.

Prognostic value of triglyceride glucose (TyG) index in patients with acute decompensated heart failure.

BACKGROUND: The triglyceride glucose (TyG) index has been proposed as a reliable marker of insulin resistance (IR) and an independent predictor of cardiovascular disease risk. However, its prognostic value in patients with acute decompensated heart failure (ADHF) remains unclear. METHODS: A total of 932 hospitalized patients with ADHF from January 1st, 2018 to February 1st, 2021 were included in this retrospective study. The TyG index was calculated as ln [fasting triglyceride level (mg/dL) × fasting plasma glucose level (mg/dL)/2]. Patients were divided into tertiles according to TyG index values. The primary endpoints were all-cause death, cardiovascular (CV) death and major adverse cardiac and cerebral events (MACCEs) during follow-up. We used multivariate adjusted Cox proportional hazard models and restricted cubic spline analysis to investigate the associations of the TyG index with primary endpoints. RESULTS: During a median follow-up time of 478 days, all-cause death, CV death and MACCEs occurred in 140 (15.0%), 103 (11.1%) and 443 (47.9%) cases, respectively. In multivariate Cox proportional hazard models, the risk of incident primary endpoints was associated with the highest TyG tertile. After adjustment for confounding factors, hazard ratios (HRs) for the highest tertile (TyG index ≥ 9.32) versus the lowest tertile (TyG index < 8.83) were 2.09 (95% confidence interval [CI], 1.23-3.55; p = 0.006) for all-cause death, 2.31 (95% CI, 1.26-4.24; p = 0.007) for CV death and 1.83 (95% CI, 1.18-3.01; p = 0.006) for MACCEs. Restricted cubic spline analysis also showed that the cumulative risk of primary endpoints increased as TyG index increased. When the TyG index was used as a continuous variable, the hazard ratios of the three primary endpoints rapidly increased within the higher range of the TyG index (all cause death, TyG > 9.08; CV death, TyG > 9.46; MACCEs, TyG > 9.87). CONCLUSIONS: The elevated TyG index was independently associated with poor prognosis, and thus would be useful in the risk stratification in patients with ADHF.

Better Islet Function and Cardiovascular Autonomic Function in Chinese Type 2 Diabetic Patients with Pure Small Fiber Neuropathy than with Mixed Neuropathy.

INTRODUCTION: The clinical characteristics and outcomes of small fiber neuropathy (SFN) in Chinese patients with type 2 diabetes mellitus (T2DM) have not been thoroughly described. In this study, we investigated the metabolic and neurological indexes and the prognosis of patients with T2DM based on skin biopsy. METHODS: A total of 34 healthy Chinese volunteers were recruited for skin biopsy to establish the reference range of intra-epidermal nerve fiber density (IENFD), and 89 patients with T2DM attending the Nanjing Drum Tower Hospital were evaluated at baseline. Of these 89 patients, 17 with pure SFN and nine with mixed diabetic polyneuropathy (DPN) were reassessed at the end of the follow-up. RESULTS: Glycated hemoglobin and postprandial blood glucose levels were lower (P = 0.005 and P = 0.041, respectively) and postprandial C-peptide and insulin levels were higher (P = 0.001 and P = 0.019, respectively) in the pure SFN group than in the mixed DPN group. A partial correlation study showed that there was a negative correlation between IENFD of the distal leg and cardiovascular autonomic reflex test (CART) scores (r = - 0.513, P = 0.001) after adjusting for age and duration of diabetes. Only vitamin B12 level (P = 0.028) and motor nerve conduction velocity (MCV) of the common peroneal nerve (P = 0.045) were increased in the patients with pure SFN at the final visit while MCVs of the common peroneal nerve (P = 0.025) and tibial nerve (P = 0.047) were decreased in the mixed DPN group at the final visit. CONCLUSION: Better islet function and cardiovascular autonomic function were observed in patients with pure SFN compared with mixed DPN. The metabolic and neurological indexes remained relatively stable in the patients with pure SFN during the follow-up.

A simple-to-use tool for predicting response to peginterferon in HBV DNA suppressed chronic hepatitis B patients in China.

BACKGROUND: Rational administration of peginterferon can remarkably reduce serum HBsAg level and improve the rate of HBsAg loss. Considering the high cost and adverse drug reaction of peginterferon, we aimed to develop a simple-to-use scoring system at early stage of treatment to predict low HBsAg level or HBsAg clearance at the end of treatment in virological suppression chronic hepatitis B (CHB) patients. METHODS: Non-cirrhotic CHB patients with NA (nucleoside/nucleotide analogues)-induced virological suppression initiated either by add-on or switch-to peginterferon for ≥ 48 weeks were enrolled from January 2012 to June 2017 in these two tertiary centers. The retrospective experiment identified 320 suitable patients, including 192 in training and 128 in validation cohorts. RESULTS: Using logistic regression, a simple-to-use scoring system integrating baseline HBsAg level <1000 IU/mL, HBsAg decline >0.5 log at week 12 and ALT flare at week 12 was developed in the training cohort and good for predicting HBsAg <100 IU/mL, HBsAg <10 IU/mL and HBsAg loss at the end of 48-week treatment. The area under receiver operating characteristics curve was 0.84, 0.86 or 0.78 in the training cohort and 0.88, 0.79 or 0.81 in the validation cohort, respectively. CONCLUSIONS: Our simple-to-use scoring system may guide for clinicians to decide whether to continue peginterferon in CHB patients to achieve low HBsAg levels or HBsAg clearance at the end of treatment, which might lead more cost-effective decision and get more patients to reach functional cures in Chinese population.

Quantitative sensory testing can effectively predict cardiovascular autonomic neuropathy in patients with type 2 diabetes mellitus.

AIMS: Cardiovascular autonomic neuropathy (CAN) is one of the most serious types of diabetic autonomic neuropathy and is a class of small fibre neuropathy. Among many inspection methods, quantitative sensory testing is an effective and convenient method for diagnosing diabetic small fibre neuropathy. This cross-sectional study aimed to identify the correlation between the development of cardiovascular autonomic neuropathy and quantitative sensory testing parameters in patients with type 2 diabetes mellitus. METHODS: A total of 266 participants with type 2 diabetes mellitus from Nanjing Drum Tower Hospital were enrolled in this study, and each of them received cardiovascular reflex tests (CARTs) and quantitative sensory testing, including testing of cold, warm, cold pain, and heat pain detection thresholds (CDT, WDT, CPT, and HPT, respectively). The results of CARTs were compared with the thermal detection thresholds in quantitative sensory testing by using SPSS 26.0. RESULTS: A total of 266 participants were divided into the CAN group, early CAN (ECAN) group, and without CAN (NCAN) group. There were significant differences in quantitative sensory testing parameters among three groups, and CARTs presented a positive correlation with the WDT and HPT and a negative correlation with the CDT. Moreover, after adjusting for age, sex, diabetes duration, and other influencing factors, WDT, HPT, and CDT were independent risk factors for cardiovascular autonomic neuropathy. CONCLUSIONS: The thermal detection thresholds, including cold, warm, and heat pain detection thresholds, in quantitative sensory testing were found to be significantly related to the results of CARTs. Some thermal detection thresholds were independent risk factors for cardiovascular autonomic neuropathy. Therefore, this study showed that quantitative sensory testing has a reliable predictive ability for the occurrence and development of cardiovascular autonomic neuropathy.

Corneal confocal microscopy: A useful tool for diagnosis of small fiber neuropathy in type 2 diabetes.

AIM: To investigate the diagnostic utility of corneal confocal microscopy (CCM) for small fiber neuropathy in type 2 diabetes. MATERIALS AND METHODS: There were 186 participants with type 2 diabetes enrolled in this cross-sectional research. Pure small fiber neuropathy and mixed fiber neuropathy were defined using clinical examination, electromyography, and quantitative sensory testing. Demographics and clinical data, corneal confocal microscopy parameters, and other neuropathy measures were compared among the groups. The diagnostic utility of corneal confocal microscopy for small fiber neuropathy was assessed by the receiver operating curve. RESULTS: Of the 186 patients, 24.7% had a pure small fiber neuropathy and 17.2% of patients were diagnosed with mixed fiber neuropathy. The corneal nerve fiber density (CNFD), corneal nerve fiber branch density (CNBD), and corneal nerve fiber length (CNFL) were significantly lower in subjects with pure small fiber neuropathy compared with those without diabetic peripheral neuropathy (all P < 0.05). The receiver operating curve analysis for corneal confocal microscopy diagnosing small fiber neuropathy demonstrated the area under the curve for CNFD of 0.791, CNFL of 0.778, CNBD of 0.710. CONCLUSIONS: Patients with type 2 diabetes with pure small fiber neuropathy showed more corneal nerve loss compared with those without diabetic peripheral neuropathy. It was revealed that corneal confocal microscopy can be a reasonable marker in the diagnosis of small fiber neuropathy in type 2 diabetes.

Application of Fatty Liver Inhibition of Progression Algorithm and Steatosis, Activity, and Fibrosis Score to Assess the Impact of Non-Alcoholic Fatty Liver on Untreated Chronic Hepatitis B Patients.

BACKGROUNDS AND PURPOSE: Concurrent non-alcoholic fatty liver disease (NAFLD) in chronic hepatitis B (CHB) patients is a frequent and increasingly concerning problem because of the NAFLD pandemic. Admittedly, NAFLD can progress to non-alcoholic steatohepatitis (NASH) and severe fibrosis. Direct evidence of the fibrotic effect of NAFLD or NASH in chronic hepatitis B virus (HBV) infection remains lacking. We aimed to reveal the influence of concurrent histologically proven fatty liver diseases in fibrogenesis with chronic HBV infection. METHODS: We performed a retrospective cross-sectional study on a liver biopsy population of CHB patients without excessive alcohol intake to evaluate the prevalence of concurrent histologically proven NAFLD or NASH according to the fatty liver inhibition of progression (FLIP) algorithm and its association with the liver fibrosis stage. RESULTS: Among 1,081 CHB patients, concurrent NAFLD was found in 404 patients (37.4%), among whom 24.0% (97/404) have NASH. The presence of NASH was an independent predictor of significant fibrosis (odds ratio (OR), 2.53; 95% CI, 1.52-4.21; p < 0.001) and severe fibrosis (OR, 1.83; 95% CI, 1.09-3.09; p = 0.023) in all patients, as well as in patients with normal alanine aminotransferase (ALT) (predicting significant fibrosis, OR, 2.86, 95% CI, 1.34-6.10; p = 0.007). The presence of lobular inflammation (p < 0.001) or presence of cytological ballooning (p < 0.001), rather than presence of steatosis (p = 0.419), was related with severity of fibrosis in Spearman's correlation analysis. CONCLUSIONS: Concurrent NAFLD is common in CHB patients, and NASH is an independent risk factor potentiating significant fibrosis by 2.53-fold and severe fibrosis by 1.83-fold. While coping with chronic HBV infection, routine assessment of co-existing NAFLD or NASH is also important.

Peginterferon and Entecavir Combination Therapy Improves Outcome of Non-Early Response Hepatitis B e Antigen-Positive Patients.

BACKGROUND: The efficacy of nucleot(s)ide analogs (NAs) and pegylated interferon (PegIFN) combination therapy for hepatitis B e antigen-positive (HBeAg+) patients is still controversial. Whether PegIFN and entecavir (ETV) combination therapy could provide a greater benefit for HBeAg+ patients was assessed. METHODS: Treatment-naïve HBeAg+ patients initiated on PegIFN alfa-2a (PegIFNα-2a) for 24 weeks without early response (early response: HBsAg <1500 IU/mL and hepatitis B virus [HBV] DNA <105 copies/mL) were recruited in the current study. Among total of 94 patients, 51 were continued on PegIFNα-2a monotherapy, and 43 were offered PegIFNα-2a and ETV combined therapy. RESULTS: Better outcomes in response to the combined therapy, compared with that of the monotherapy, were demonstrated, including more HBsAg decline and loss and HBV DNA decline and HBeAg clearance. Importantly, the patients with HBsAg levels between 1500 and 20 000 IU/mL initially or between 5000 and 20 000 IU/mL after 24 weeks of PegIFNα-2a benefitted more from the combined therapy, compared with those on monotherapy. CONCLUSIONS: Combined therapy of PegIFNα-2a and ETV is more efficacious for HBeAg+ patients without early response to PegIFN monotherapy, and HBsAg levels are a good predictor of treatment outcomes.

Purse-string sutures using novel endoloops and repositionable clips for the closure of large iatrogenic duodenal perforations with single-channel endoscope: a multicenter study.

BACKGROUND: Serious complications due to perforation restrict the development of duodenal endoscopic treatment. The key stage for remediation is the successful endoscopic closure to prevent peritonitis and the need for surgical intervention. This report aimed to present a new simple method for the closure of large iatrogenic duodenal perforations with purse-string sutures using the novel endoloops and repositionable clips through a single-channel endoscope. METHODS: A total of 23 patients with iatrogenic duodenal perforations ≥ 1 cm were retrospectively studied who were presently treated by purse-string sutures using the novel endoloops and the repositionable hemostasis clips with the single-channel endoscope at four institutes. During and after the procedure, a 20-gauge needle was used to relieve the pneumoperitoneum or subcutaneous emphysema. Finally, a gastroduodenal decompression tube was placed. RESULTS: The median maximum diameter of iatrogenic duodenal perforations was 1.65 cm (range 1.0-3.0 cm). Complete endoscopic closure of all 23 perforations was achieved. No patient had severe complications such as peritonitis. The wounds were healed and no obvious duodenal stricture was observed in all cases after 3 months. CONCLUSION: Purse-string sutures using the novel endoloops and repositionable endoclips through single-channel endoscope were feasible, effective and easy methods for the closure of large duodenal iatrogenic perforations.
