Nonalcoholic Fatty Liver Disease as a Risk Factor for Severe Cholangitis.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is one of the most prevalent chronic liver disorders. Acute cholangitis (AC) is a life-threatening illness. OBJECTIVES: To determine whether NAFLD is a risk factor for the severity of AC. METHODS: We retrospectively studied hospitalized patients with a diagnosis of AC over 5 years. Patients were divided into a NAFLD group and a non-NAFLD group. We compared the two groups with regard to demographic characteristics, co-morbidities, laboratory data, and severity of AC (including Charlson Comorbidity Index [CCI] and Tokyo Consensus meeting criteria). RESULTS: In all, 298 of 419 hospitalized patients diagnosed with AC met the inclusion criteria. Of these, 73/298 (24.5%) were in the NAFLD group. NAFLD group patients were younger and more likely to be diabetic and obese than the non-NAFLD group. Participants in the NAFLD presented with higher serum C-reactive protein and higher liver enzymes (P < 0.05, for each parameter) and with more events of organ dysfunction (P < 0.001) and bacteremia (P < 0.005). Regarding the severity of AC according to Tokyo Consensus, among the NAFLD group more patients presented with Grade II (39.7 vs. 33.3%, P < 0.001) and Grade III (23.3 vs. 18.3, P < 0.001) cholangitis. More Grade I cholangitis was found among the non-NAFLD group (48.4 vs. 37%, P < 0.001). Multivariate logistic regression analysis showed that NAFLD was independently associated with severe AC, Grade III (odds ratio 3.25, 95% confidence interval 1.65-6.45, P = 0.038). CONCLUSIONS: NAFLD is an independent risk factor for the severity of AC.

Plasma Glycated Hemoglobin A1c Could Predict 30-Day All-cause Mortality of Intensive Care Unit Patients with Hyperglycemia.

BACKGROUND: An increased serum glucose level is a common finding among patients admitted to hospital with acute illness, including the intensive care unit (ICU), even without a history of previous diabetes mellitus (DM). Glycated hemoglobin (HbA1c) is not only a diagnostic tool for DM but may also has prognostic value for diabetic and non-diabetic populations. OBJECTIVES: To assess the relationship between HbA1c level on admission and clinical outcome among patients admitted to the ICU due to cardiopulmonary disorders with hyperglycemia. METHODS: Patients consecutively admitted to the ICU due to cardiopulmonary disorders who presented with hyperglycemia at admission were evaluated during a 6-month period. HbA1c and serum glucose levels were tested on admission and during the first 24-48 hours of hospitalization. Patients were divided according to HbA1c and compared in term of demographics. We evaluated the effect of HbA1c levels at admission on the clinical outcomes. RESULTS: Of patients with cardiopulmonary disorders who presented with hyperglycemia at admission to the ICU, 73 had HbA1c levels ≥ 6%, 92 had HbA1c levels < 6%: 63/165 (38.2%) known as diabetic patients. The 30-day all-cause mortality was higher in the group with high HbA1c levels; 38/73 vs. 32/98 (P = 0.02). Increased length of stay in the ICU and Acute Physiology and Chronic Health Evaluation II (APACHE II) score were associated with HbA1c ≥ 6% (P < 0.022 and P < 0.026), respectively. CONCLUSIONS: HbA1c ≥ 6% has an important clinical prognostic value among diabetic and non-diabetic patients with cardiopulmonary disorders and hyperglycemia.

Impact of Prior Statin Therapy on 1-year Recurrence and Length of Hospitalization for Acute Idiopathic Pericarditis.

BACKGROUND: Statins have anti-inflammatory effects that are independent of their lipid-lowering activity. OBJECTIVES: To examine whether prior statins therapy affects the clinical course of the first episode of acute idiopathic pericarditis (AIP) as the 1-year recurrence and length of hospitalization (LOH). METHODS: This retrospective study included 148 subjects with first episode AIP admitted between the years 2015 and 2019. Data were collected from two hospitals in Northern Israel. We divided the patients in into two groups: 117 those without statins use and 31 those with prior statins use. We compared age, sex, co-morbidities, drugs, laboratory data, 1-year recurrence, and LOH. RESULTS: The mean age of participants was 43.1 ± 19.4 years. Comparisons between subjects without statins and with prior statins use were made according to age (37.5 ± 16.7 years vs. 64.4 ± 12.7 years, P < 0.01), C-reactive protein (50 ± 40 vs. 48 ± 35 mg/dl, P = 0.9), LOH (5.4 ± 2.85 vs. 8.03 ± 4.92 days, P < 0.01), 1-year recurrence of pericarditis (23 vs. 6 cases, P = 0.95), respectively. Multivariate logistic regression analysis revealed that 1-year recurrence (odds ratio [OR] 0.8, 95% confidence interval [95%CI 0 0.6-1.1, P = 0.41), was not associated with prior statin use, while LOH (OR 2.56, 95%CI 2.08-2.75, P = 0.01) was prolonged with prior statins use in patients with first episode of AID. CONCLUSIONS: Prior statins use in patients with the first episode of AIP did not reduce the 1-year recurrence of pericarditis and prolong the LOH.

Diarrhea due to parasites: a short, updated point of view from the clinical setting.

Diarrhea represents a common manifestation of several gastrointestinal diseases. Infectious agents are the most common causes of diarrhea in developing countries, where the inadequate sanitation and hygiene are prevalent. In these countries, the scarcity of preventive measures as well as the limited health resources cause a substantial increase in incidence, morbidity and mortality due to infectious diseases, including diarrhea. Currently, with the availability of rapid and inexpensive air transportation millions of people travel for tourism, work and immigration from developing countries to industrialized countries and vice versa. This leads to a high number of imported pathogens such as parasites causing infectious diarrhea. Importantly, while most cases of parasitic diarrhea are short, mild and self-limited, other cases may be associated with chronic diarrhea and serious morbidity and mortality. The aim of the current review was to provide an update, from a clinician's point of view, of the main parasites causing diarrhea, with a focus on their diagnosis and management in the clinical setting.

Serum Albumin to Creatinine Ratio as Predictor for 30-Day All-Cause Mortality in Patients with Clostridium Di!cile-Associated Diarrhea.

BACKGROUND: Clostridium difficile-associated diarrhea (CDAD) is a significant cause of mortality and morbidity in hospitalized patients. Several scores have developed in order to assess the severity of CDAD. OBJECTIVE: To determine the role of the serum albumin to creatinine ratio (sACR) in predicting the 30-day all-cause mortality of patients with CDAD in comparison with other known severity scores of CDAD. METHODS: A retrospective study was conducted at Baruch-Padeh Medical Center from January 2014 to December 2019. Patients with CDAD were recruited from Internal Medicine Departments, Intensive Care Units, and Surgical Departments. Data on demographic characteristics, clinical signs, underlying conditions, and several risk factors for CD infection were collected. We compared between severity scores of CDAD, such as ATLAS, the CDAD severity score, and the sACR in predicting the 30-day all-cause mortality in hospitalized patients with CDAD. RESULTS: 116 patients with CDAD were included. The ATLAS, CDAD scores, and sACR were calculated for all patients. The mean age of the participants was 71.4±16.4 years. 57.7% were of female gender. Fifty-two (44.8%) died within 30 days. An ATLAS score of ≥8 points had a 3.6-fold higher risk of 30-day all-cause mortality in hospitalized patients with CDAD (HR 3.6, 95% CI 3.28-3.99, p=0.001), a CDAD score of ≥5 points (HR 1.1, 95% CI 0.91-1.42, p=0.05), and a sACR≤3.4 (HR 1.5, 95%CI 1.25-1.82, p=0.04). CONCLUSION: In this study, it was found that a sACR≤3.4 could predict the 30-day all-cause mortality in patients with CDAD.

Low serum potassium levels are associated with the risk of atrial fibrillation.

BACKGROUND: Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice. AF is associated with approximately a threefold to fivefold increased risk for stroke. Hypokalaemia is associated with ventricular arrhythmias and cardiac arrest. Little is known about the association of serum potassium with atrial fibrillation. AIMS: The aims of this study are to assess the association of low serum potassium (hypokalaemia) and the risk of AF. METHODS: Retrospective data were collected for all patients' records, who were hospitalised at department of Internal Medicine of Ziv Medical Centre, Safed, Israel, from January 2013 to December 2017 with AF. Clinical data were obtained from patient's hospital records. We excluded those who were pregnant, diagnosed with malignancy and those with thyrotoxicosis. Control group consisted of patients who were hospitalised in the same period with normal sinus rhythm (NSR). We compared between the two groups in term of age, gender, comorbidities and serum levels of potassium and magnesium. RESULTS: We enrolled 281 subjects with AF who responded to our study purposes. The control group consistend of 260 with NSR. Hypokalaemia of less than 3.5 mmol/l was found in 16% in the study group vs. 8.4% in control group, p = 0.001. Multivariate regression analysis showed that OR 2.08, 95% CI (1.378-3.138), p = 0.01, and hypokalaemia < 3.5 mmol/l OR1.827, 95%CI (1.50-3.179), p = 0.02 were found to be associated with atrial fibrillation. CONCLUSION: We found that low serum potassium levels of less than 3.5 mmol/l are associted with increased risk of AF.

Neutrophil-to-lymphocyte ratio and red blood cell distribution width as predictors of microalbuminuria in type 2 diabetes.

BACKGROUND AND AIM: Chronic inflammation has an important role in the development and progression of type 2 diabetes through immunologic inflammatory mechanisms. Simple new inexpensive inflammatory markers may contribute to the detection of microalbuminuria. Aim of our study is to evaluate the predictive value of neutrophil-to-lymphocyte ratio (NLR), mean platelet volume (MPV), and red blood cell distribution width (RDW) for microalbuminuria in type 2 diabetic patients for possible application as prognostic factors for the prediction of microalbuminuria and the progression of disease in patients with diabetes. METHODS: A total of 168 patients with type 2 diabetes mellitus were classified into gender- and BMI-matched three groups according to hemoglobin A1c and microalbuminuria: Group A: 53 patients with controlled diabetes, Group B: 57 patients with uncontrolled diabetes, both without microalbuminuria, and Group C: 58 patients with uncontrolled diabetes with microalbuminuria. Levels of NLR, MPV, and RDW between the study groups were examined and compared. RESULTS: A significant difference in NLR was found between Group C and groups A and B (P < .001, P = .005, respectively). A statistically significant difference in RDW was found between groups B and C (P = .014). Receiver operating characteristic curve analysis of inflammatory markers and microalbuminuria prediction showed an area under curve (AUC) of 0.675 for NLR (CI 0.58-0.76, P < .001) and 0.614 for RDW (CI 0.52-0.70, P = .013). NLR value of 2.54 has 39.7% sensitivity, 78.8% specificity, and 45% positive predictive value (PPV). RDW value of 14.44 has 37.9% sensitivity, 76% specificity, and 41.5% PPV. CONCLUSIONS: Neutrophil-to-lymphocyte ratio and RDW have PPV for microalbuminuria in diabetic patients.

The role of neutrophil-lymphocyte ratio, and mean platelet volume in detecting patients with acute venous thromboembolism.

BACKGROUND: Acute venous thromboembolism (VTE) refers to deep venous thrombosis (DVT) of the extremities or pulmonary embolism (PE), or to both. Reliable imaging is not always available making a serologic diagnosis, or biomarker, highly desirable. OBJECTIVE: This study aimed to examine the role of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and mean platelet volume (MPV) in detection patients with acute VTE. METHODS: A total of 327 patients with initial diagnosis of acute VTE who were admitted to Ziv hospital were evaluated. Of them, 272 patients with definitive diagnosis of VTE, and 55 patients without VTE were used as control group. Complete blood count (CBC), measurements of NLR, MPV, and PLR were determined at admission. RESULTS: Patients with VTE were older than controls (62 ± 18.9 vs 55.4 ± 15.1 years, respectively, P = .03). Female gender was predominant in the two groups. In the study group, 178/272 (66%) had DVT, 84/272 (31%) had pulmonary embolism (PE), and the rest had DVT and PE. NLR, MPV, and PLR were found to be significantly elevated in acute VTE compared to control (P < .001, P = .008, P = .014, respectively). A ROC curve analysis of NLR and MPV for predicting acute VTE was performed which found a cut-off value of 5.3 for NLR, an area under curve of (0.67 (0.60-0.75), P < .001, with a sensitivity of 69% and specificity of 57%. and a cut-off value of 8.6 for MPV, an area under curve of (0.61 [0.53-0.68], P = .014, with a sensitivity of 52% and specificity of 67%. Multivariate logistic regression model found that NLR (OR 1.2, 95% CI [1.01-1.4], P = .041) and MPV (OR 1.5, 95%CI [1.07-2.12], P = .5) were associated with acute VTE. CONCLUSIONS: Neutrophil-lymphocyte ratio and MPV could be beneficial predictors for the early detection of potential acute VTE.

Impact of pretreatment with carnitine and tadalafil on contrast-induced nephropathy in CKD patients.

Objective: The present study assesses whether phosphodiesterase type 5 (PDE-5) inhibitor or carnitine exert nephroprotective effects against clinical contrast-induced nephropathy (CIN).Materials and Methods: The present study consisted of three groups of CKD patients. The first group was control group, who were treated with N-acetyl-L-cysteine 1 day before and on the day of radiocontrast administration. The second one was carnitine group, where the patients were infused with carnitine over 10 min 2 h prior to the radiocontrast administration and 24 h post CT. The third one was PDE-5 inhibitor group, where patients were given tadalafil 2 h prior to the administration of the radiocontrast and in the subsequent day. Urine and blood samples were collected before and at the following time sequence: 2, 6, 12, 24, 48, and 120 h after the contrast administration, for creatinine and NGAL determination.Results: Pretreated with N-acetyl-L-cysteine prior to administration of contrast media (CM) to CKD patients caused a significant increase in urinary but not of plasma neutrophil gelatinase-associated lipocalin (NGAL) and serum creatinine (SCr). In contrast, pretreatment with carnitine prevented the increase in urinary NGAL and reduced SCr below basal levels. Similarly, tadalafil administration diminished the elevation of CM-induced urinary NGAL.Conclusions: These results indicate that carnitine and PDE-5 inhibitors may comprise potential therapeutic maneuvers for CIN.

Non-alcoholic fatty liver disease: a survey of involvement of primary care physicians.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are neglected in most patients' electrical medical report by their family physicians (FP). We have assessed whether family physicians have the proper knowledge of NAFLD and accurate training to diagnose and treat NAFLD/NASH in overweight and obese patients. METHODS: We conducted an anonymous survey questionnaire. Family Physicians who participated completed 4 years of residency and have passed the final examination. Our survey contained questions to measure the physician's attitudes, source of knowledge and recommendation regarding NAFLD/NASH treatment and attitudes toward patients with NAFLD/NASH. Categorical variables were extracted and analyzed using SPSS. RESULTS: A total of 310 of 422 FPs were included in the study with a compliance rate of 73%. Our data suggests that 167 of the 310 FPs (55%) refer their patients to a specialist for consultations if they exhibited fatty liver disease. Yet, 284 of 310 send their patients to consolations if exhibiting elevated liver enzyme. Our data significantly suggests that 241 of 310 (78%) reported that they have limited efficacy in treating NAFLD/NASH and consider themselves not properly prepared, by medical schools, to treat NASH/NAFLD patients; as well as patients with obesity and metabolic syndrome without fatty liver. CONCLUSIONS: FPs are more likely to neglect proper treatment for NAFLD/NASH due to lack of proper knowledge and are more likely neglect referring patients to specialist. Patients with significant obesity and obesity related conditions are more likely to have proactive treatment plans by their FPs.

The Prognostic Value of Inflammatory Markers in Clostridium difficile-associated Diarrhea.

BACKGROUND: The incidence of Clostridium difficile-associated diarrhea (CDAD) is increasing and is associated with significant morbidity and mortality. Therefore, there is a need to find new tools to determine the severity of the disease. OBJECTIVES: To investigate the prognostic values of inflammatory markers such as mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR), and C-reactive protein (CRP) in patients with CDAD. METHODS: The study comprised of 100 patients diagnosed with CDAD. The study included an additional control group of 69 patients with diarrhea who were negative for C. difficile toxin. The control group was age- and sex-matched and hospitalized at the same time period. NLR and MPV were obtained from complete blood count results. Serum CRP levels were measured by the latex particle enhanced immunoturbidimetric assay. Blood samples for all inflammatory markers were collected at time of diagnosis and prior to initiating the antibiotic therapy. Demographic, clinical, laboratory, and prognostic data were collected from medical records for a period of 90 days from the initial diagnosis of CDAD. RESULTS: The mean age of the CDAD group was 68.6 ± 21.5 years compared to 65.6 ± 24.5 in the control group (P = 0.29). Our findings show that patients with CDAD had significantly higher NLR, MPV and serum CRP levels compared to the control group (P < 0.001)). Moreover, significantly higher levels were observed when CDAD was fatal (P < 0.001). CONCLUSIONS: Elevated NLR, MPV, and serum CRP levels may serve as biomarkers for prediction of recurrence and mortality in patients with CDAD.

Non-alcoholic Fatty Liver Disease is Associated with Recurrent Urinary Tract Infection in Premenopausal Women Independent of Metabolic Syndrome.

BACKGROUND: Recently, studies have found that non-alcholic fatty liver disease (NAFLD) is associated with bacterial infections. Attempts to identify risk factors for recurrent urinary tract infections (rUTIs) are still underway. OBJECTIVES: To examine a possible association between NAFLD and rUTIs among premenopausal women. METHODS: In a case-control study, 1009 hospitalized premenopausal women with a UTI during a period of 3 years were retrospectively studied. A total of 186 subjects with rUTIs and 186 controls without a history of rUTIs were included in this study. Each participant had an abdominal ultrasonogram as part of the inclusion criteria. The two groups were compared in terms of risk factors for rUTIs, such as maternal history of rUTIs, use of contraceptives, frequency of sexual intercourse, metabolic syndrome, obesity, use of probiotics, serum levels of vitamin D, and NAFLD. An rUTI was defined as three or more episodes of UTI over a period of 1 year. NAFLD was diagnosed based on abdominal ultrasonography examination. RESULTS: Mean age of the 372 participants was 39.7 ± 5 years. NAFLD was diagnosed in 81/186 subjects (43.5%) with rUTIs vs. 40/186 controls (21.5%), P = 0.05. Women with rUTIs were more often obese and presented with lower serum levels of vitamin D than controls. Multivariate analysis showed that NAFLD (odds ratio = 1.6, 95% confidence interval 1.3-2.0, P = 0.04) were associated with rUTIs in premenopausal women. CONCLUSIONS: NAFLD was associated with rUTI in premenopausal women, independent of metabolic syndrome. Further studies are needed to confirm this association.

Omadacycline for Community-Acquired Bacterial Pneumonia.

BACKGROUND: Omadacycline, a new once-daily aminomethylcycline antibiotic agent that can be administered intravenously or orally, reaches high concentrations in pulmonary tissues and is active against common pathogens that cause community-acquired bacterial pneumonia. METHODS: In a double-blind trial, we randomly assigned (in a 1:1 ratio) adults with community-acquired bacterial pneumonia (Pneumonia Severity Index risk class II, III, or IV) to receive omadacycline (100 mg intravenously every 12 hours for two doses, then 100 mg intravenously every 24 hours), or moxifloxacin (400 mg intravenously every 24 hours). A transition to oral omadacycline (300 mg every 24 hours) or moxifloxacin (400 mg every 24 hours), respectively, was allowed after 3 days; the total treatment duration was 7 to 14 days. The primary end point was early clinical response, defined as survival with improvement in at least two of four symptoms (cough, sputum production, pleuritic chest pain, and dyspnea) and no worsening of symptoms at 72 to 120 hours, without receipt of rescue antibacterial therapy. A secondary end point was investigator-assessed clinical response at a post-treatment evaluation 5 to 10 days after the last dose, with clinical response defined as resolution or improvement in signs or symptoms to the extent that further antibacterial therapy was unnecessary. A noninferiority margin of 10 percentage points was used. RESULTS: The intention-to-treat population included 386 patients in the omadacycline group and 388 patients in the moxifloxacin group. Omadacycline was noninferior to moxifloxacin for early clinical response (81.1% and 82.7%, respectively; difference, -1.6 percentage points; 95% confidence interval [CI], -7.1 to 3.8), and the rates of investigator-assessed clinical response at the post-treatment evaluation were 87.6% and 85.1%, respectively (difference, 2.5 percentage points; 95% CI, -2.4 to 7.4). Adverse events that emerged after treatment initiation were reported in 41.1% of the patients in the omadacycline group and 48.5% of the patients in the moxifloxacin group; the most frequent events were gastrointestinal (10.2% and 18.0%, respectively), and the largest difference was for diarrhea (1.0% and 8.0%). Twelve deaths (8 in the omadacycline group and 4 in the moxifloxacin group) occurred during the trial. CONCLUSIONS: Omadacycline was noninferior to moxifloxacin for the treatment of community-acquired bacterial pneumonia in adults.

Fatal thoracic aortic aneurysm and dissection in a large family with a novel MYLK gene mutation: delineation of the clinical phenotype.

BACKGROUND: Thoracic and abdominal aortic aneurysms and dissection often develop in hypertensive elderly patients. At higher risk are smokers and those who have a family history of aortic aneurysms. In most affected families, the aortic aneurysms and dissection is inherited in an autosomal dominant manner with decreased penetrance and variable expressivity. Mutations at two chromosomal loci, TAA1 at 11q23 and the TAA2 at 5q13-14, and eight genes, MYLK, MYH11, TGFBR2, TGFBR1, ACTA2, SMAD3, TGFB2, and MAT2A, have been identified as being responsible for the disease in 23% of affected families. RESULTS: Herein, we inform on the clinical, genetic and pathological characteristics of nine living and deceased members of a large consanguineous Arab family with thoracic aortic aneurysm and dissection who carry a missense mutation c.4471G > T (Ala1491Ser), in exon 27 of MYLK gene. We show a reduced kinase activity of the Ala1491Ser protein compared to wildtype protein. This mutation is expressed as aortic aneurysm and dissection in one of two distinct phenotypes. A severe fatal and early onset symptom in homozygous or mild late onset in heterozygous genotypes. CONCLUSIONS: We found that MYLK gene Ala1491Ser mutation affect the kinase activity and clinically, it presents with vascular aneurysms and dissection. We describe a distinct genotype phenotype correlation where; heterozygous patients have mild late onset and incomplete penetrance disease compared with the early onset severe and generally fatal outcome in homozygous patients.

Relationship between Non-Alcoholic Fatty Liver Disease and Breast Cancer.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease which refers to the presence of hepatic steatosis. Breast cancer is now the most common cancer in women and is the leading cause of death from cancer among women. OBJECTIVES: To assess the relationship between NAFLD and newly diagnosed cases of breast cancer. METHODS: The results of mammography screening examinations in women referred to the Breast Center, Holy Family Hospital, Nazareth during a 4 year period were collected. We identified cases of women who were newly diagnosed with breast cancer and who underwent abdominal computed tomography (CT) within 1 month of the diagnosis. The control group comprised 73 women with normal mammography and breast ultrasonography who underwent abdominal CT within 3 months from the date of the breast cancer screening during the same study period. The control cases were matched by age and body mass index (BMI). We compared the cases with the controls in terms of the presence of diffuse hepatic fatty liver and other known risk factors for breast cancer. RESULTS: Of the 133 women who were screened, 73 with new diagnosis of breast cancer were eligible for the study. NAFLD was found in 33 of the women with breast cancer and in 12 in the control group (45.2% vs.16.4%, respectively, P = 0.002). Multivariate analysis showed NAFLD (odds ratio 2.82, 95% confidence interval 1.2-5.5, P = 0.016) to be associated with breast cancer. CONCLUSIONS: NAFLD is associated with breast cancer.

Association between Fatty Liver Disease and Hyperplastic Colonic Polyp.

BACKGROUND: Hyperplastic polyps (HPs) of the colon are the most common colorectal polyps. Metabolic syndrome components such as obesity and hyperlipidemia are considered the most common etiological factors for HPs as well contributing to the pathogenesis of fatty liver disease. OBJECTIVES: To determine the possible association between biopsy-proven steatohepatitis and hyperplastic colonic polyps. METHODS: This retrospective cohort observational study conducted at the Holy Family Hospital in Nazareth, Israel, included subjects who underwent screening colonoscopy over a 2 year period. Data were extracted from the patient charts and included demographics, anthropometric measurements, vital signs, underlying diseases, medical therapy, laboratory data, and results of the liver biopsy. The colonoscopy report and pathological report of each extracted polyp were also evaluated. RESULTS: A total of 223 patients were included in the study: 123 patients with biopsy-proven non-alcoholic steatohepatitis (NASH) and 100 patients without NASH who served as the control. Fourteen colonic adenomas (11% of patients) were found in the NASH group vs. 16 (16%) in the control group (P = 0.9); 28 HPs were found in the NASH group (22.7%) vs. 8 in the control group (8%) (P < 0.05). The multivariate analysis, after adjusting for, age, C-reactive protein and smoking, showed that the presence of NASH (OR 1.69, 95%CI 1.36-1.98, P < 0.01) was associated with increased risk for HP. CONCLUSIONS: Our study found an association between biopsy-proven steatohepatitis and the burden of hyperplastic polyp.

Advanced Hepatic Fibrosis in Fatty Liver Disease Linked to Hyperplastic Colonic Polyp.

Aim. Our study aims to determine possible association between biopsy-proven nonalcoholic steatohepatitis (NASH) and hyperplastic polyps (HP) of the colon. Methods. A retrospective cohort observational study. All subjects underwent screening colonoscopy within two years. Data were extracted from the patient charts including demographic, anthropometric measurement, vital signs, underlying diseases, medical therapy, laboratory data, results of the liver biopsy with degree of fibrosis and necroinflammatory activity, the colonoscopy report, and the pathological report of the extracted polyp. Results. A total of 223 patients were included in our study, 123 patients with biopsy-proven NASH and 100 patients without NASH who served as the control group matched for age. 14 colonic adenomas (11% of patients) were found in the NASH group compared with 16 adenomas (16% of patients) found in the control group (P = 0.9). 28 HPs were found in the NASH group (22.7%) compared with only 8 HPs in the control group (8%) (P < 0.05). 21 from the 28 (75%) HPs diagnosed in the NASH group were observed in the high degree fibrosis patients (Fibrosis Stages 3 and 4), 6 HPs (21%) were associated with Fibrosis Stages 1 and 2, and single HP (4%) was associated with Fibrosis Stage 0. Conclusions. Our study showed an association between biopsy-proven steatohepatitis and the burden of hyperplastic polyp. The severity of hepatic fibrosis may play important role in the increased occurrence of HPs.

Superb Microvascular Imaging: Added Value and Novel Applications.

Determining the presence and characteristics of vascular flow is an essential part of sonography interrogation. However, small vessels and low velocities are not always possible to depict with conventional color and power Doppler ultrasound. This can be frustrating, especially when the diagnosis depends mainly on the existence of vascular flow, the sonographic examination will be inconclusive, further imaging examinations will be required and diagnosis delayed. Superb microvascular imaging (SMI) is a novel vascular imaging mode, which provides visualization of low velocity and microvascular flow. SMI uses a clutter suppression algorithm to extract flow signals and depicts this information as a color overlay image or as a monochrome or color map of flow. By using SMI, high frame rates and high-resolution images remain maintained. With SMI, it is possible to visualize small vessels including their branches that, until now, it is possible to demonstrate only using contrast-enhanced ultrasound. Availability of this additional technology on all ultrasound machines may make some of the computed tomography scans unnecessary. In our paper, we describe six patients, aged 16-73 years, in which final diagnosis was achieved only with SMI and where conventional color and power Doppler failed. All these examinations were performed using Aplio 500 Platinum ultrasound unit (Toshiba Medical Systems, Tokyo, Japan).
