Balloon Dilation Eustachian Tuboplasty for Dilatory Dysfunction With and Without Effusion: A Comprehensive Outcome Analysis.

OBJECTIVE: This study aimed (1) to demonstrate the efficacy of balloon dilation Eustachian tuboplasty (BDET) for dilatory Eustachian tube dysfunction (ETD) and (2) to determine whether adjunctive ventilation tube insertion (VTI) is superior to myringotomy in relieving symptoms for patients with ETD and concurrent middle ear effusion (MEE) treated with BDET. STUDY DESIGN: A retrospective cohort study. SETTING: Tertiary care academic center. METHODS: Patients with dilatory ETD undergoing BDET with a ≥6-month follow-up period were enrolled and evaluated mainly using Eustachian tube function (ETF) tests and Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7). Participants with concurrent MEE were further classified into 2 subgroups, BDET with VTI and BDET with myringotomy. An intergroup comparison and comprehensive outcome evaluation were performed. RESULTS: In total, 35 patients with 50 symptomatic ears were enrolled. According to ETF test results, the normalized ETF rate was 94% on the last visit. The mean ETDQ-7 scores decreased significantly from 3.7 ± 1.4 to 2.0 ± 0.9 after interventions, with the most improvement in symptoms occurring for "ear fullness" and "muffled hearing." For the final visit, strong correlations among ETF tests, tympanometry, and Valsalva results were noted. The aforementioned assessment results did not significantly differ between (1) the patients with MEE and patients without MEE and (2) "BDET with VTI" subgroup and "BDET with myringotomy" subgroup. CONCLUSION: BDET was effective for dilatory ETD, even in cases with concurrent MEE. For patients with ETD and MEE, further research is required to evaluate the benefits of adjunctive myringotomy with or without VTI.

An experience in treatment of neurologically silent clival chordoma mimicking a nasopharyngeal tumor.

Cranial chordoma is a rare neoplasm that is challenging to both diagnose and manage. We present our experience in treating a case of clival chordoma mimicking a nasopharyngeal mass without any signs of cranial deficits or intracranial insult. Management was comprised of endoscopic transnasal debulking surgery followed by radiotherapy. However, we failed to achieve an oncologic outcome due to the development of lethal central nervous system and respiratory infections 1 month after the surgery.

Elevated Serum Interleukin-8 Level Correlates with Cancer-Related Cachexia and Sarcopenia: An Indicator for Pancreatic Cancer Outcomes.

Cancer cachexia (CC), characterized by body weight loss and sarcopenia, contributes to over 20% of all cancer-related death. Approximately 80% of pancreatic cancer (PC) patients develop CC during disease progression. Pro-inflammatory cytokines, including interleukin (IL)-1ß, IL-6, IL-8, and tumor necrosis factor (TNF)-α, have been correlated with CC; however, its prognostic significance remains unclear. In this study, serum levels of the CC-related cytokines were determined in normal donors and PC patients. IL-8 expression was assessed in PC tissue microarrays. The correlation of levels of each cytokine with disease progression, weight loss, and sarcopenia was calculated. The relationships among the baseline variables, CC, and IL-8 expression with disease progression were examined using univariate and multivariate analyses. Of these mentioned cytokines, only serum IL-8 level was elevated in the locally advanced group (n = 55) compared with the normal (n = 17) and resected groups (n = 55). Serum IL-8 level was positively correlated with CC status, weight loss, sarcopenia, but was negatively correlated with total psoas area (TPA). IL-8 expression in tissue samples was also positively associated with weight loss. Furthermore, serum IL-8 level was an independent predictor of survival. In conclusion, elevated serum IL-8 level significantly correlates with CC and sarcopenia and can be used as a prognostic indicator in PC.

Elevated body mass index is a risk factor associated with possible liver cirrhosis across different etiologies of chronic liver disease.

BACKGROUND/PURPOSE: Metabolic risk factors are associated with liver fibrosis. Whether or not metabolic risk factors affect the severity of liver fibrosis in patients with chronic hepatitis B (CHB), chronic hepatitis C (CHC), or risk factors associated with non-alcoholic fatty liver disease (NAFLD) remains unclear. We aimed to investigate this by transient elastography. METHODS: In this cross-sectional study, we enrolled 1513 patients who presented with chronic liver disease (CLD) at a tertiary hospital. Liver stiffness measurement (LSM) >13 kPa was used as a cutoff suggesting possible liver cirrhosis (LC). RESULTS: Possible LC was noted in 7.8% of the CHB patients, 19.9% of the CHC patients, and 11.9% of the patients with risk factors associated with NAFLD. After adjustments for biochemical and virological factors were made, BMI (per 1 kg/m2 increase) (OR: 1.17, 95% CI: 1.06-1.29, P = 0.002) was found to be an independent factor associated with possible LC in CHB patients; BMI (per 1 kg/m2 increase) (OR: 1.15, 95% CI: 1.07-1.24, P < 0.001) and diabetes mellitus (DM) (OR: 2.32, 95% CI: 1.25-4.30, P = 0.008) were found to be independent factors associated with possible LC in CHC patients; and BMI (per 1 kg/m2 increase) (OR: 1.19, 95% CI: 1.07-1.32, P = 0.002) and DM (OR: 10.35, 95% CI: 2.95-36.32, P < 0.001) were found to be independent factors associated with possible LC in patients with risk factors associated with NAFLD. CONCLUSION: Elevated BMI was an independent risk factor associated with possible LC across the three different etiologies of CLD. As such, weight loss may be beneficial in these patients.

The association between steatosis and diabetes with hepatocellular carcinoma in non-genotype 3 chronic hepatitis C patients.

BACKGROUND & AIMS: Diabetes mellitus (DM) has been found to be strongly associated with an increased risk of hepatocellular carcinoma (HCC) among chronic hepatitis C (CHC) patients. Several studies have also found an association between metabolic steatosis and the risk of HCC in CHC patients, whether this latter association has been accounted for by the known relationship between DM and HCC is still unknown. METHODS: A cohort consisting of 976 non-genotype 3 patients histologically proven to have CHC and treated with interferon and ribavirin was studied. Cumulative incidence and HCC risk were analysed using the Kaplan-Meier method and Cox proportional hazard analysis. RESULTS: Hepatocellular carcinoma developed in 140 subjects over a median follow-up period of 97.3 months, while 699 patients achieved sustained virological response (SVR). According to multivariate analyses, age ≥ 60 years, advanced fibrosis and genotype 1 were identified as independent factors significantly associated with HCC development in SVR patients. Furthermore, using the absence of steatosis and absence of DM as references, the presence of steatosis without DM (HR = 2.09, 95% CI = 1.12-3.9, P = .021), the presence of DM without steatosis (HR = 2.78, 95% CI = 1.3-5.92, P = .008) and the combined presence of steatosis and DM (HR = 3.25, 95% CI = 1.44-7.33, P = .004) were identified as independent factors significantly associated with HCC development in the SVR patients. In contrast, steatosis alone, DM alone and the combined presence of steatosis and DM were not associated with HCC development in non-SVR patients. CONCLUSIONS: Steatosis and DM may be associated with HCC development in non-genotype 3 CHC patients with SVR.

Association between PNPLA3 (rs738409 C>G) variant and hepatocellular carcinoma in Asian chronic hepatitis C patients: A longitudinal study.

BACKGROUND/PURPOSE: Prdevious meta-analyses assess whether or not patatin-like phospholipase domain containing 3 (PNPLA3) (rs738409 C > G) was associated with increased risk of hepatocellular carcinoma (HCC) in Caucasians patients with hepatitis C virus (HCV)-related cirrhosis, these meta-analyses did not provide firm conclusions. Only one cross-sectional study involving Asian patients has previously been conducted to explore this issue. We aim to investigate this in a longitudinal cohort of Asian chronic hepatitis C (CHC) patients. METHODS: We consecutively enrolled 1011 CHC patients who underwent liver biopsy before initiating interferon-based therapy. These patients were followed-up and screened for HCC up to a median of 6.9 years. The influence of rs738409 (GG) genotype on the occurrence of HCC was assessed using the Kaplan-Meier method, then according to the multivariate Cox model. RESULTS: During follow-up, 143 (14.1%) patients developed HCC. rs738409 (GG) genotype was not associated with time-to-HCC development on multivariate Cox regression (P = 0.634). When considering the occurrence of these events over time, rs738409 (GG) genotype did not influence the risk of HCC development (log-rank = 0.12). Among 261 patients with liver cirrhosis, rs738409 (GG) genotype was not associated with time-to-HCC development on multivariate Cox regression (P = 0.737). When considering the occurrence of these events over time, rs738409 (GG) genotype did not influence the risk of HCC development (log-rank = 0.72). CONCLUSION: In this longitudinal study with liver biopsy to stage liver fibrosis, we affirm there is no influence of the rs738409 (GG) genotype on the occurrence of HCC in Asian CHC patients, including cirrhotic patients.

The correlation of controlled attenuation parameter results with ultrasound-identified steatosis in real-world clinical practice.

BACKGROUND/PURPOSE: Controlled attenuation parameter (CAP) is a method for measuring steatosis based on FibroScan. Despite observer dependency, ultrasound (US) robustly diagnoses moderate and severe steatosis. Here, we aimed to evaluate the correlation of CAP with US-identified steatosis in real-world clinical practice. METHODS: CAP and US were performed for 1554 chronic liver disease (CLD) patients. CAP was performed by two technicians, and US was performed by 30 hepatologists. The performance of the CAP as compared with the US results was assessed using the area under the receiver operating characteristic curve (AUROC). RESULTS: 532 (34.2%) of the patients had hepatitis C virus (HCV) infection, 723 (46.5%) of the patients had hepatitis B virus (HBV) infection, and the rest were patients with metabolic risk factors. CAP values were significantly correlated with the steatosis grades identified by US for all the patients (ρ = 0.497, P < 0.001), for the HBV-infected patients (ρ = 0.495, P < 0.001), for the HCV-infected patients (ρ = 0.343, P < 0.001), and for the patients with metabolic risk factors (ρ = 0.515, P < 0.001). Using CAP, the AUROC values were 0.759, 0.795, 0.715, and 0.716 for ≥moderate steatosis identified by US in, respectively, all the patients, the HBV-infected patients, the HCV-infected patients, and the patients with metabolic risk factors. The AUROC values were 0.791, 0.868, 0.807 and 0.701 for severe steatosis identified by US in, respectively, all the patients, the HBV-infected patients, the HCV-infected patients, and the patients with metabolic risk factors. CONCLUSION: CAP values were well correlated with the steatosis grades assessed by US in real-world clinical practice.

Transient elastography as a screening tool for liver fibrosis in a large hemodialysis population.

Metabolic syndrome, an etiological factor in non-alcoholic fatty liver disease (NAFLD), is often present in hemodialysis patients. Little is known about the prevalence of, and factors associated with, liver fibrosis in hemodialysis populations. We used transient elastography (TE) to investigate these phenomena. 659 patients treated with chronic hemodialysis were enrolled. We excluded those with excess alcohol intake, liver stiffness measurement (LSM) failure, or unreliable LSM values. LSM ≥8.0 kPa was used as a cutoff suggesting clinically relevant fibrosis. Controlled attenuation parameter (CAP) ≥ 232.5 dB/m was used as a cutoff suggesting steatosis. 333 patients (50.5%) had steatosis, 159 (24.1%) had hepatitis B or C, and 149 (22.6%) had LSM ≥8.0 kPa. In multivariable analyses, male gender (OR: 2.16; 95% CI: 1.29-3.63; P = 0.004), overweight body habitus (OR:2.31; 95% CI: 1.35-3.94; P = 0.002), high AST level (OR:1.08; 95% CI: 1.04-1.12; P < 0.001), low albumin level (OR: 0.25; 95% CI: 0.12-0.53; P < 0.001), low creatinine level (OR: 0.89; 95% CI: 0.79-1.00; P = 0.05) and low platelet count (OR: 0.99; 95% CI: 0.99-1.00; P < 0.001) were associated with LSM ≥8.0 kPa. We thus conclude that hemodialysis patients have a high prevalence of NAFLD and clinically relevant fibrosis. NAFLD may be an important determinant of clinically relevant fibrosis in hemodialysis populations.
