The Role of Whole-Body Magnetic Resonance Imaging in Assessing Extrapulmonary Metastases in Osteosarcoma Staging and Restaging: A Pilot Study.

OBJECTIVE: The aim of the study is to investigate the role of whole-body magnetic resonance imaging (MRI) in assessing extrapulmonary metastases in primary osteosarcoma staging. METHODS: We retrospectively reviewed medical data to identify primary osteosarcoma patients with available preoperative whole-body MRI obtained in the staging or restaging. Histopathology was the reference test for assessing the diagnostic performance, if available. Otherwise, oncology board decisions were used as the reference. In addition, the benefits of whole-body MRI to F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) and bone scintigraphy were investigated. RESULTS: In all, 36 patients with osteosarcoma (24 staging, 12 restaging) with a mean age of 16.36 ± 5.63 years (range, 9-29 years) were included in the study. The median follow-up duration was 26.61 months (interquartile range, 33.3 months). Of 36 patients, 8 had skeletal, 1 had a lymph node, and 1 had a subcutaneous metastasis. Whole-body MRI correctly identified all patients with metastatic disease but incorrectly classified a bone infarct in one patient as a skeletal metastasis, equating a scan-level sensitivity, specificity, accuracy, negative predictive value, and positive predictive value of 100%, 96.3%, 97.3%, 100%, and 90.91%. Whole-body MRI contributed to bone scintigraphy by identifying a skeletal metastasis in one patient and positron emission tomography-computed tomography by ruling out a skeletal metastasis in another. CONCLUSIONS: Whole-body MRI could accurately identify extrapulmonary metastases in primary osteosarcoma patients for staging or restaging. In addition, it might contribute to the standard whole-body imaging methods.

The value of MRI contrast enhancement in biopsy decision of suspicious mammographic microcalcifications: a prospective multicenter study.

OBJECTIVES: To investigate the inclusion of breast MRI in radiological assessment of suspicious, isolated microcalcifications detected with mammography. METHODS: In this prospective, multicenter study, cases with isolated microcalcifications in screening mammography were examined with dynamic contrast-enhanced MRI (DCE-MRI) before biopsy, and contrast enhancement of the relevant calcification localization was accepted as a positive finding on MRI. Six experienced breast radiologists evaluated the images and performed the biopsies. Imaging findings and histopathological results were recorded. Sensitivity, specificity, NPV, and PPV of breast MRI were calculated and compared with histopathological findings. RESULTS: Suspicious microcalcifications, which were detected by screening mammograms of 444 women, were evaluated. Of these, 276 (62.2%) were diagnosed as benign and 168 (37.8%) as malignant. Contrast enhancement was present in microcalcification localization in 325 (73.2%) of the cases. DCE-MRI was positive in all 102 invasive carcinomas and in 58 (87.9%) of 66 DCIS cases. MRI resulted in false negatives in eight DCIS cases; one was high grade and the other seven were low-to-medium grade. The false-negative rate of DCE-MRI was 4.76%. The sensitivity, specificity, PPV, and NPV for DCE-MRI for mammography-detected suspicious microcalcifications were 95.2%, 40.2%, 49.2%, and 93.3%, respectively. CONCLUSIONS: In this study, all invasive cancers and all DCIS except eight cases (12.1%) were detected with DCE-MRI. DCE-MRI can be used in the decision-making algorithm to decrease the number of biopsies in mammography-detected suspicious calcifications, with a tradeoff for overlooking a small number of DCIS cases that are of low-to-medium grade. KEY POINTS: • All invasive cancer cases and 87.8% of all in situ cancer cases were detected with MRI, showing a low false-negative rate of 4.7%. • Dynamic contrast-enhanced MRI can be used in the decision-making algorithm to decrease the number of biopsies in mammography-detected suspicious calcifications, with a tradeoff for overlooking a small number of DCIS cases that are predominantly low-to-medium grade. • If a decision for biopsy were made based on MRI findings in mammography-detected microcalcifications in this study, biopsy would not be performed to 119 cases (26.8%).

[Unilateral congenital aplasia of the submandibular gland]. / Submandibüler bezin tek tarafli dogustan aplazisi.

Aplasia of the major salivary glands is very uncommon, whereas isolated aplasia of unilateral submandibular gland is even rarer. In this article, we report a 55-year-old female case in whom unilateral aplasia of the left submandibular gland was detected incidentally by ultrasonography with no other congenital comorbidities in the light of literature data.

Interdisiplinary and intraobserver reliability of the Greulich-Pyle method among Turkish children.

OBJECTIVES: Greulich-Pyle (GP) is one of the most used method for bone age determination (BAD) in various orthopedic, pediatric, radiological, and forensic situations. We aimed to investigate the inter- and intra-observer reliability of the GP method between the most relevant disciplines and its applicability to the Turkish population. METHODS: One-hundred and eighty (90 boys, 90 girls) patients with a chronological age younger than 18 (mean 9.33) were included. X-rays mixed by the blinded investigator were evaluated by two orthopedists, two radiologists, and two pediatric endocrinologists to determine skeletal age according to the GP atlas. A month later the process was repeated. As a statistical method, Paired t-test was used for comparison, an Intraclass Correlation Coefficients test was used for reliability and a 95 % confidence interval was determined. Results were classified according to Landis-Koch. RESULTS: All results were consistent with chronological age (p<0.001), according to the investigators' evaluations compared with chronological age. At the initial evaluation, the interobserver reliability of the method was 0.999 (excellent); at the second evaluation, the interobserver reliability was 0.997 (excellent). The intra-observer reliability of the method was 'excellent' in all observers. When results were separately evaluated by gender, excellent intraobserver correlation and excellent correlation with chronological age were found among all researchers (>0.9). When X-rays were divided into three groups based on age ranges and evaluated, 'moderate' and 'good' correlations with chronological age were obtained during the peripubertal period. CONCLUSIONS: The GP method used in skeletal age determination has excellent inter- and intra-observer reliability. During the peripubertal period, potential discrepancies in bone age assessments should be kept in mind. This method can be used safely and reproducibly by the relevant specialists.

Characterization of nonalcoholic fatty liver disease unrelated to the metabolic syndrome.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome (MS). However, not all patients with the MS will develop NAFLD and not all patients with NAFLD have the MS. We sought to investigate the differences between patients with biopsy-proven NAFLD with and without the MS. METHODS: A total of 357 consecutive patients with biopsy-proven NAFLD were analysed. Of them, 216 patients had nonalcoholic steatohepatitis (NASH) and 96 a fibrosis score ≥ 2. The MS was defined as ≥ 3 of the ATP III criteria. RESULTS: A total of 214 patients with NAFLD met the criteria for the MS, while the remaining 143 did not. In NAFLD patients with the MS, homeostasis model of insulin resistance (P = 0·03; OR, 1·06; 95% CI, 1·023-1·25 per unit increase) and diabetes (P = 0·01; OR, 1·2; 95% CI, 1·1-2·4) were independent predictors of NASH. In NAFLD patients without the MS, the only variable independently associated with NASH was haemoglobin (P = 0·007; OR, 1·9; 95% CI, 1·4-3·6 per 50 g/L increase). Alanine aminotransferase (P = 0·03; OR, 1·04; 95% CI, 1·006-1·11 per 10 U/L increase) was an independent predictor of fibrosis ≥ 2 in NAFLD patients with the MS, while haemoglobin (P = 0·02; OR, 1·4; 95% CI, 1·2-1·9 per 50 g/L increase) was the only variable significantly associated with fibrosis ≥ 2 in NAFLD patients without the MS. CONCLUSIONS: Increased haemoglobin in NAFLD subjects without MS should be considered in the selection of cases for histological assessment.

The impact of early percutaneous endoscopic gastrostomy placement on treatment completeness and nutritional status in locally advanced head and neck cancer patients receiving chemoradiotherapy.

To investigate the impact of early insertion of percutaneous endoscopic gastrostomy-tube on nutritional status and completeness of concurrent chemotherapy in locally advanced head and neck cancer patients treated with chemoradiotherapy. Twenty-three patients were enrolled into this prospective study. Gastrostomy-tube was inserted in patients before the initiation of chemoradiotherapy. There was not any significant change in nutritional parameters of patients that used their tube during treatment. Despite the grade 3 mucositis, the planned concurrent chemotherapy could be given in 70% of the patients. However, nine patients had weak compliance and their body weight (P = 0.01) and body mass index (P = 0.01) deteriorated in the first 4 weeks of chemoradiotherapy. The completeness of concurrent chemo-rate was 44% in these patients. Toxicity, requiring aggressive supportive care, may limit the chemotherapy part of curative concomitant chemoradiotherapy. By providing adequate enteral nutrition the insertion of gastrostomy-tube can increase the completeness rate of concurrent chemotherapy.

Serum levels of omentin, chemerin and adipsin in patients with biopsy-proven nonalcoholic fatty liver disease.

OBJECTIVE: The novel adipokines omentin, chemerin, and adipsin are associated with insulin resistance and the components of the metabolic syndrome. We assayed circulating levels of these molecules and examined their association with clinical, biochemical, and histological phenotypes in patients with nonalcoholic fatty liver disease (NAFLD). MATERIAL AND METHODS: Serum levels of omentin, chemerin, and adipsin were assayed by enzyme-linked immunosorbent assay in 99 patients with biopsy-proven NAFLD and 75 control subjects. We analyzed associations between adipokines and the characteristics of patients with NAFLD using multivariable linear regression models. RESULTS: Adipsin levels did not differ between patients and controls, whereas both omentin and chemerin levels were significantly higher in patients with biopsy-proven NAFLD than in controls (both p values <0.001). Serum omentin levels were significantly associated with C-reactive protein (r = 0.29, p < 0.01) and the degree of hepatocyte ballooning (r = 0.27, p < 0.01), whereas chemerin showed a modest association with liver fibrosis (r = 0.22, p = 0.04). After stepwise linear regression analysis adjusting for potential confounders, serum omentin levels retained their independent significance as a predictor of hepatocyte ballooning in patients with NAFLD (ß = 1.42; t = 2.79, p < 0.01). CONCLUSIONS: Our results suggest that serum omentin levels are raised in patients with NAFLD regardless of potential confounders and represent an independent predictor of hepatocyte ballooning.

Serum zinc-α2-glycoprotein concentrations in patients with non-alcoholic fatty liver disease.

BACKGROUND: Evidence suggests that zinc-α(2)-glycoprotein (ZAG) might serve as a biomarker for human metabolic alterations. We measured serum ZAG in patients with non-alcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome, and examined its association with clinical, biochemical, and histological phenotypes. METHODS: Serum ZAG was determined using ELISA in 90 patients with biopsy-proven NAFLD and 81 controls. RESULTS: Serum ZAG concentrations did not differ in patients with NAFLD (median 61 µg/mL; interquartile range: 56-73 µg/mL) compared with healthy controls (median 66 µg/mL; interquartile range: 56-78 µg/mL, Mann-Whitney U-test, p=NS). However, among patients with NAFLD serum ZAG concentrations were significantly higher in males and in those with the metabolic syndrome. After stepwise linear regression analysis, serum ZAG concentrations were the only independent predictor of the number of metabolic syndrome components in patients with NAFLD (ß=0.22; t=2.001, p<0.05). CONCLUSIONS: In summary, the hypothesis of an association between NAFLD and serum ZAG concentrations is not supported by the present results. However, ZAG remains an interesting molecule for further research in the field of human metabolic disorders.

A case of mediastinal lymphangioma: endosonographic appearance.

Mediastinal lymphangioma is a rare, benign disease characterized by an abnormal proliferation of lymphatic vessels. Although a definitive diagnosis can be best made by surgical resection, computed tomography (CT) and magnetic resonance imaging (MRI) can be used as radiological methods to diagnose a pulmonary lymphangioma preoperatively. Endoscopic ultrasonography is a new method for visualizing pathological changes in the mediastum and may be used for preoperative diagnosis of a pulmonary lymphangioma, which is a rare example of a mediastinal disease.

Increased serum FGF21 levels in patients with nonalcoholic fatty liver disease.

BACKGROUND: The fibroblast growth factor 21 (FGF21) hormonal pathway is a metabolic signalling cascade and has been recently identified as the master hormonal regulator of glucose, lipids and overall energy balance. In this observational, case-control study, we assayed serum levels of FGF21 in patients with nonalcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome, and examined their association with clinical, biochemical and histological phenotypes. MATERIALS AND METHODS: Serum levels of FGF21 were assayed by ELISA in 82 patients with biopsy-proven NAFLD and 77 controls. We analysed associations between FGF21 and the characteristics of patients with NAFLD by multiple linear regression analysis. RESULTS: Levels of FGF21 were significantly higher in patients with NAFLD (median 200 pg mL(-1) ; interquartile range: 87-410 pg mL(-1)) than in healthy controls (median 93 pg mL(-1) ; interquartile range: 70-180 pg mL(-1) , Mann-Whitney U-test, P<0·001). There was a stepwise increase in serum FGF21 levels according to the liver steatosis score (median level in subjects with score 1: 170 pg mL(-1) ; score 2: 220 pg mL(-1) ; score 3: 280 pg mL(-1) , P for trend <0·01). After stepwise linear regression analysis, serum FGF21 levels were the only independent predictor of hepatic steatosis scores in patients with NAFLD (ß=0·26; t=2·659, P<0·01). CONCLUSIONS: Serum FGF21 levels are increased in patients with NAFLD regardless of potential confounders and represent an independent predictor of liver steatosis. These findings support further investigation of this molecule in metabolic liver diseases.

Serum levels of osteoprotegerin in the spectrum of nonalcoholic fatty liver disease.

OBJECTIVE: Osteoprotegerin (OPG) is a member of the tumor necrosis factor superfamily with pleiotropic effects on inflammation, endocrine function and the immune system. Reduced OPG levels are related to insulin resistance. We tested the hypothesis that serum levels of OPG may be associated with nonalcoholic fatty liver disease (NAFLD). MATERIAL AND METHODS: Four groups of patients were enrolled in the present study: subjects with definite nonalcoholic steatohepatitis (NASH, n = 56), borderline NASH (n = 26), simple fatty liver (n = 17) and healthy controls without evidence of liver disease (n = 58). Serum levels of OPG were measured by ELISA. RESULTS: Concentrations of OPG were significantly lower in patients with definite NASH (median: 45 pg/mL, p < 0.001) and borderline NASH (57 pg/mL, p < 0.001) than in controls (92 pg/mL). The area under the ROC curve for distinguishing between steatohepatitis (definite NASH plus borderline NASH) and healthy controls using OPG was 0.82. The use of a cut-off level < 74 pg/mL for serum OPG levels yielded sensitivity and specificity values of 75.6% and 75.9%, respectively. CONCLUSIONS: Serum osteoprotegerin concentrations are reduced in patients with the more severe forms of NAFLD and may serve as a noninvasive biomarker to identify patients with NASH.

Dipeptidyl peptidase IV inhibitors: therapeutic potential in nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease is the most common chronic liver disease in industrialized countries and is considered the hepatic manifestation of metabolic syndrome. Apart from correction of underlying metabolic abnormalities, restriction of caloric intake, and physical exercise, no drugs have been licensed for the treatment of nonalcoholic fatty liver disease. Of note, reduced caloric intake and exercise with resultant weight loss may lead to a reduction in liver fat content, but no studies have shown long-term benefits of this. Dipeptidyl peptidase IV inhibitors are promising new oral drugs for the treatment of type 2 diabetes. Here, we hypothesize that dipeptidyl peptidase IV inhibitors can reduce fat infiltration in the liver and thus be a potential treatment for nonalcoholic fatty liver disease. There are 3 lines of evidence supporting this hypothesis. First, dipeptidyl peptidase IV inhibitors are known to improve insulin resistance, a key metabolic abnormality encountered by patients with nonalcoholic fatty liver disease. Second, patients with nonalcoholic steatohepatitis have increased dipeptidyl peptidase IV activity, which has been found to correlate positively with the histopathologic grade and degree of liver steatosis. Finally, data from experimental studies suggest that dipeptidyl peptidase IV inhibitors can reduce liver inflammation and steatosis. In light of these findings, we propose that pharmacologic inhibition of dipeptidyl peptidase IV may provide a new therapeutic option for slowing the progression of nonalcoholic fatty liver disease. Future research is expected to support the efficacy and tolerability of dipeptidyl peptidase IV modulation in early liver steatosis.

Calcific tendinitis: intramuscular and intraosseous migration.

Calcific tendinitis is a well-documented and extensively studied disease in the literature. Intramuscular and intraosseous migration are rare complications, which may present diagnostic challenges. This pictorial essay illustrates the imaging findings of these complications. Considering that neoplastic processes and infectious diseases are included in the differential diagnosis, recognizing the imaging findings of these complications is of critical importance.

Esomeprazole in acute and maintenance treatment of reflux oesophagitis: a multicentre prospective study.

INTRODUCTION: The aim of this study was to assess the efficacy and safety of esomeprazole 40 mg once daily (q.d.) in healing reflux oesophagitis at 4 and 8 weeks, and the efficacy of esomeprazole 20 mg q.d. for 12 weeks in the maintenance of remission. METHODS: A total of 235 patients with endoscopically proven reflux oesophagitis were enrolled in this study, which consisted of two phases (healing and maintenance therapy). Patients who showed complete endoscopic and symptomatic healing at the end of 4 or 8 weeks were switched to maintenance treatment with esomeprazole 20 mg q.d. for 12 weeks. The primary efficacy endpoint was healing of reflux oesophagitis at week 8. Secondary assessments included the proportion of patients with symptomatic relapse in the maintenance phase. RESULTS: At the end of week 8, 88% (95% life-table confidence intervals [CI]: 84%, 92%) of patients were healed endoscopically and 90.6% of the patients were asymptomatic. Patient age, gender and Helicobacter pylori status had no effect on the efficacy of treatment. During the 12-week maintenance treatment phase, symptomatic relapse ratios were 0.5%, 2.2%, and 0%, for the first, second, and third 4-week periods, respectively. The proportions of patients satisfied with treatment were 95% and 99.4% at the end of acute and maintenance treatment, respectively. The most common adverse effects were headache, upper respiratory tract infection and abdominal pain. CONCLUSIONS: Esomeprazole is effective in the healing of reflux oesophagitis, the resolution of heartburn, and in maintaining symptomatic remission. The effectiveness of esomeprazole in patients with gastroesophageal reflux disease is not affected by the presence of H. pylori.

Determination of hepatitis B genotypes in patients with chronic hepatitis B virus infection in Turkey.

BACKGROUND/AIMS: There are significant variations in the geographic distribution of hepatitis B virus genotypes throughout the world, and some genotypes are associated with different clinical outcomes. Eight genotypes of human hepatitis B virus (designated A-H) have been described to date. To determine the hepatitis B virus genotypes in Turkish patients with chronic liver disease and compare the results with clinical characteristics of the patients. METHODS: Fifty-four (pediatric: n=25 and adult: n=29) patients with chronic hepatitis B virus infection and with an hepatitis B virus DNA level above 5 pg/ml were entered into the trial. Restriction fragment length polymorphism method was used to determine hepatitis B virus genotype and their restriction fragment length polymorphism patterns. Hepatitis B virus DNA samples of 13 patients were sequenced automatically for further confirmation of restriction fragment length polymorphism results. RESULTS: Genotype D was the dominant genotype in all of our cases. Among six restriction fragment length polymorphism patterns of genotype D reported in the literature, three (D1, D2, D6) were present in our series and D2 was the most frequent restriction fragment length polymorphism pattern (81.5%). No significant differences were observed among different genotype D restriction fragment length polymorphism patterns with respect to patients' serum ALT, AST, and hepatitis B virus DNA titer, but D2 restriction fragment length polymorphism pattern was significantly more common in younger adults compared to D1 restriction fragment length polymorphism pattern. CONCLUSION: Genotype D with D2 restriction fragment length polymorphism pattern is the dominant hepatitis B virus genotype in all age groups in Turkey.

Botulinum toxin injection versus lateral internal sphincterotomy in the treatment of chronic anal fissure: a non-randomized controlled trial.

BACKGROUND: Although lateral internal sphincterotomy is the gold-standard treatment for chronic anal fissure, intrasphincteric injection of botulinum toxin seems to be a reliable new option. The aim of this non-randomized study is to compare the effect of lateral internal sphincterotomy and botulinum toxin injection treatments on the outcome and reduction of anal sphincter pressures in patients with chronic anal fissure. METHODS: Patients with chronic anal fissure were treated with either botulinum toxin injection or lateral internal sphincterotomy by their own choice. Maximal resting pressure and maximal squeeze pressure measurements were performed before and 2 weeks after treatments by anal manometry. Patients were followed for fissure relapse during 14 months. RESULTS: Twenty-one consecutive outpatients with posterior chronic anal fissure were enrolled. Eleven patients underwent surgery and ten patients received botulinum toxin injection treatment. Before the treatment, anal pressures were found to be similar in both groups. After the treatment, the maximal resting pressures were reduced from 104 +/- 22 mmHg to 86 +/- 15 mmHg in the surgery group (p < 0.05) and from 101 +/- 23 mmHg to 83 +/- 24 mmHg in the botulinum toxin group (p < 0.05). The mean maximal squeeze pressures were reduced from 70 +/- 27 mmHg to 61 +/- 32 mmHg (p > 0.05) in the surgery group, and from 117 +/- 62 mmHg to 76 +/- 34 (p < 0.01) in the botulinum toxin group. The fissures were healed in 70 percent of patients in the botulinum group and 82 percent in the surgery group (p > 0.05). There were no relapses during the 14 months of follow up. CONCLUSION: Lateral internal sphincterotomy and botulinum toxin injection treatments both seem to be equally effective in the treatment of chronic anal fissure.

Isolated sphenoid fungal sinusitis and coexisting intrasellar mass lesion presenting with headache as the sole symptom.

A case of isolated sphenoid fungal sinusitis in an elderly diabetic patient is described. A coexisting mass lesion located in the sellar region was detected incidentally. Coincidence of these two entities represents a potential surgical disaster which may result in direct intracranial spread of fungal infection.

Helicobacter pylori: management in 2013.

Helicobacter pylori (H. pylori) is a prevalent, worldwide, chronic infection. Choice of treatment can be modified according to antibiotic-resistance rates of H. pylori. The ideal therapeutic regimen for H. pylori infection should achieve an eradication rate of ≥ 80%. In some countries, triple therapy with a proton-pump inhibitor (PPI), clarithromycin, and amoxicillin or metronidazole is still the best option. Bismuth-containing quadruple therapy consisting of bismuth salts, tetracycline, metronidazole and PPI, may be the preferred option in countries with clarithromycin resistance > 20%. Sequential therapy including a PPI and amoxicillin given for the first 5 d, followed by triple therapy including a PPI, clarithromycin, and nitroimidazole antimicrobial (all twice daily) for the remaining 5 d, can be another option for the first-line treatment of H. pylori. Recent data suggest that treatment with PPI, levofloxacin, and amoxicillin for 10 d is a good choice for second-line therapy. Concomitant therapy consisting of PPI, amoxicillin, clarithromycin and metronidazole is another option for second-line treatment. If second-line treatment also fails, it is recommended to culture H. pylori from biopsy specimens and perform antimicrobial susceptibility testing. Rescue treatment should be based on antimicrobial susceptibility.

Effects of sitagliptin in diabetic patients with nonalcoholic steatohepatitis.

BACKGROUND & AIMS: Preliminary evidence suggests that inhibition of dipeptidyl peptidase (DPP)-IV preserves pancreatic beta cell function in patients with type 2 diabetes (T2D). However, its effects on liver histology in nonalcoholic steatohepatitis (NASH), hepatic complication of diabetes, have not yet been adequately explored. The present open-label, single-arm observational pilot study investigated the effects of one year of treatment with a dipeptidyl peptidase-IV inhibitor, sitagliptin, on liver histology, body mass index (BMI), and laboratory parameters in NASH patients with T2D. PATIENTS AND METHODS: Paired liver biopsies from 15 diabetic patients with NASH (7 males, 8 females; mean age: 49.7 +/- 8.1 years (range: 36-62)) before and after one year of therapy with sitagliptin 100 mg once daily were studied. Clinical and laboratory parameters were recorded. RESULTS: Treatment with sitagliptin resulted in a significant decrease in ballooning (P = 0.014) and NASH scores (P = 0.04), while the reduction in the steatosis score was of borderline statistical significance (P = 0.054). These effects were accompanied by a significant reduction in body mass index, AST, and ALT levels. CONCLUSION: Our study suggests that sitagliptin ameliorates liver enzymes and hepatocyte ballooning in NASH patients with T2D and may have therapeutic implications.
