RESUMO

Hepatitis B virus may reactivate in patients with chronic hepatitis C treated with direct-acting antivirals. The aim of this study was to investigate the risk of hepatitis B virus (HBV) reactivation in HBV + hepatitis C virus (HCV)-co-infected patients with compensated liver cirrhosis treated with paritaprevir/ombitasvir/ritonavir, dasabuvir with ribavirin. We reviewed prospectively gathered data from a national cohort of 2070 hepatitis C virus patients with compensated liver cirrhosis who received reimbursed paritaprevir/ombitasvir/r, dasabuvir with ribavirin for 12 weeks from the Romanian National Health Agency during 2015-2016. Twenty-five patients in this cohort were HBs antigen positive (1.2%); 15 untreated with nucleotide analogues agreed to enter the study. These patients were followed up: ALT monthly, serology for HBV and DNA viral load at baseline, EOT and SVR at 12 weeks. Hepatitis B virus (HBV)-co-infected patients were all genotype 1b and 52% females, with a median age of 60 years (51 ÷ 74); 76% were pretreated with peginterferon + ribavirin; 72% were with severe necroinflammatory activity on FibroMax assessment; 40% presented comorbidities; and all were HBe antigen negative. Hepatitis C virus (HCV) SVR response rate was 100%. Hepatitis B virus (HBV)-DNA viral load was undetectable in 7/15 (47%) before therapy, and for the other 8 patients, it varied between below 20 and 867 IU/mL. Five patients (33%) presented virological reactivation (>2 log increase in HBV-DNA levels) during therapy. One patient presented with hepatitis associated with HBV reactivation, and two started anti-HBV therapy with entecavir. Hepatitis B virus (HBV) virological reactivation was present in 33% in our patients. Generally, HBV-DNA elevations were mild (<20 000 IU/mL); however, we report one case of hepatitis associated with HBV reactivation.

RESUMO

CONTEXT: Nonalcoholic fatty liver disease is common in type 2 diabetes mellitus patients, being difficult to diagnose. OBJECTIVE: To find a correlation between elastographic parameters and lab results, for facilitating the diagnosis of nonalcoholic fatty liver disease. DESIGN: This is a cross sectional study, conducted at the Departments of Diabetes, Nutrition and Metabolic Diseases, and Gastroenterology and Hepatology, of the Clinical Emergency Hospital "Pius Brinzeu" Timisoara. SUBJECTS AND METHODS: We included 190 type 2 diabetes mellitus patients, collected data regarding medical history, clinical and biological features and applied the Alcohol Use Disorders Identification Test. We excluded patients with other causes of liver disease. Liver steatosis and fibrosis were evaluated through transient elastography, yielding two parameters: liver stiffness as an indicator of liver fibrosis stage, expressed in kPa, and liver steatosis stage, assessed by controlled attenuation parameter, expressed in dB/m. Data were analyzed using SPSS 15. RESULTS: The analyzed group comprised 113 patients. Elastographic measurements showed that 93.8% of the patients had steatosis (controlled attenuation parameter ≥232.5 dB/m) and 70.8% severe steatosis (controlled attenuation parameter ≥290 dB/m). Severe steatosis was more common in women (75.7%) than in men (68.1%) (p<0.0001). From the patients with steatosis, 47.2% had liver stiffness values suggestive for fibrosis and 19.8% for cirrhosis. Most patients with steatosis and severe fibrosis were obese (66.7%). Triglycerides/HDLc ratio >4 correlated with hepatic steatosis (p=0.04), being more common in patients with severe fibrosis/cirrhosis (58.3%) than in those with absent or mild fibrosis (36.2%). CONCLUSIONS: Our study found a clear correlation between type 2 diabetes mellitus and the presence of liver steatosis. It correlates with body mass index, waist circumference (in men) and triglycerides/HDLc ratio. Controlled attenuation parameter is a useful noninvasive method for detection and quantification of liver steatosis.

RESUMO

The relationship between the kidney and other organs is notable. The best known is the relation with the cardiovascular system. Relationships with other organs are less studied, although their involvement sometimes dominates the clinical picture and the outcome of disease. The paper analyzes the kidney-liver relationship, namely chronic kidney disease and chronic liver disease from an immune viewpoint. The immune system operates as a unitary whole. There is an interdependence between the immune system of the liver, considered a lymphoid organ, and the kidney, whose participation in immune processes is well-known. The most important chronic liver diseases are viral hepatitis B and C. Infection with these viruses can lead to renal involvement, producing mainly glomerular disease. At the same time, secondary glomerulonephritis can cause an unfavorable outcome of the primary disease. The relationship between chronic liver disease and chronic kidney disease during chronic B and C hepatitis occurs via circulating immune complexes or complexes formed in situ. Cell-mediated immunity is also involved. The antiviral treatment of B and C hepatitis is also aimed at secondary glomerular disease. The participation of immune mechanisms raises the question of administering immunomodulating medication, a type of medication that influences viral replication--this is why it is associated with antiviral medication. Other two chronic liver diseases, namely liver cirrhosis, in which the main mechanism is a toxic one, and non-alcoholic steatohepatitis can produce via immune mechanisms glomerular involvement. In its turn, chronic kidney disease in advanced stages causes lipid metabolism disturbances with hypertriglyceridemia, which can influence fatty loading of the liver in the above-mentioned liver diseases. One can speak about a cross-talk between the liver and the kidney, in which immune mechanisms play an important role.

RESUMO

Colorectal cancer is a major health problem in the world. It can be detected in asymptomatic early stages so screening programs have been implemented in many countries for many years. Unfortunately, in Romania, the screening program for the detection of colonic pathologies is still not working. This paper suggests that an opportunistic colorectal cancer screening may be a solution in our country. This means that when a physician is contacted by a subject older than 50 years, a colorectal screening procedure--fecal occult blood testing or colonoscopy should be suggested to him/her. Thus, by collaborating between physicians from many specialties (gastroenterologists, general practitioners, internal medicine specialists, and surgeons) we hope to decrease the rate of advanced colorectal cancers found in daily practice.

RESUMO

UNLABELLED: HCV is an important cause of renal disease. Taal and Brenner have identified risk factors for CKD and have suggested that these risk factors be incorporated into a renal risk score analogous to the Framingham cardiovascular score. Given the high HCV-renal disease comorbidity, we sought to assess risk factors for CKD in patients with HCV chronic hepatitis. METHODS: One hundred-seventeen patients with HCV chronic hepatitis (mean age: 50.68 +/- 9.14 years; 86 female and 31 male) hospitalized in the Department of Hepatology during 2009 were enrolled into the study. All patients were assessed for the risk factors for CKD proposed by Taal and Brenner: albuminuria, diabetes mellitus, hypertension, obesity, anemia, hypercholesterolemia, hypertriglyceridemia, nephrotoxins, primary renal disease, associated urological disorder, cardiovascular disease and family history of CKD. Renal function (GFR-CKD-Epi) was also evaluated. STATISTICAL ANALYSIS: Pearson's correlation coefficient and Odds Ratio (OR) was performed using SPSS17 and Epi 3.2.2. RESULTS: The prevalence of albuminuria was 21.36%, of hypertension was 20.51%, of obesity was 21.36%, and hypercholesterolemia was present in 41.02% of the cases. Renal function was as follows: 10.25% (12/117) of the patients had a GFR < 60 mL/min/1.73 sqm.; 64.95% (76/117) of the patients had a GFR between 60-89 mL/min/1.73 sqm.; and 24.78% (29/117) had a GFR > or = 90 mL/min/1.73 sqm. CONCLUSIONS: Our study shows that HCV chronic hepatitis is associated with renal function impairment in a high percentage of patients. Prominent risk factors for CKD are present in these patients, such as albuminuria, hypertension, obesity, and hypercholesterolemia, which need to be actively searched and addressed therapeutically.

RESUMO

PURPOSE: To assess the value of contrast-enhanced ultrasound (CEUS) for differentiating malignant from benign focal liver lesions (FLLs) and for diagnosing different FLL types. MATERIAL AND METHODS: CEUS performed in 14 Romanian centers was prospectively collected between February 2011 and June 2012. The inclusion criteria were: age > 18 years; patients diagnosed with 1 - 3 de novo FLLs on B-mode ultrasound; reference method (computed tomography (CT), magnetic resonance imaging (MRI) or biopsy) available; patient's informed consent. FLL lesions were characterized during CEUS according to the European Federation of Societies for Ultrasound in Medicine and Biology guidelines. For statistical analysis, indeterminate FLLs at CEUS were rated as false classifications. RESULTS: A total number of 536 cases were included in the final analysis, 344 malignant lesions (64.2 %) and 192 benign lesions (35.8 %). The reference method was: CT/MRI - 379 cases (70.7 %), pathological exam - 150 cases (27.9 %) and aspiration of liver abscesses - 7 cases (1.4 %). CEUS was conclusive in 89.3 % and inconclusive in 10.7 % of cases. To differentiate between malignant and benign FLLs, CEUS had 85.7 % sensitivity, 85.9 % specificity, 91.6 % positive predictive value, 77.1 % negative predictive value and 85.8 % accuracy. The CEUS accuracy for differentiation between malignant and benign liver lesions was similar in tumors with diameter ≤ 2 cm and those with diameter > 2 cm. CONCLUSION: CEUS represents a useful method in clinical practice for differentiating between malignant and benign FLLs detected on standard ultrasonography, and the results of this study are in concordance with previous multicenter studies: DEGUM (Germany) and STIC (France).

RESUMO

AIM: The aim of the study was to evaluate the benefit of the immunochemical fecal blood test (FIT) for detection of advanced adenomas. MATERIAL AND METHODS: We have conducted a screening study on a average-risk cohort of subjects, aged 50 -74 years. We used a rapid quantitative FIT to perform the screening. Colonoscopy was recommended in all participants with positive FIT. We assessed the participation rate and analyzed advanced adenomas detected in the screening examinations. RESULTS: Our study enrolled 1111 asymptomatic participants. Immunochemical test results were positive in 72 subjects (6.5%). Colonoscopy was performed by 50/72 (69.4%) subjects. The detection rate for advanced adenomas was 2.2%. A total number of 28 advanced adenomas were detected in 24 subjects, meaning 1.2 advanced adenoma/subject. Analyzing the 3 characteristics of advanced adenomas, we observed in our study that 25/28 adenomas (89.3%) had sizes > or = 10 mm, 11/28 adenomas (39.3%) were tubulovillous/villous and 19/28 adenomas (67.9%) had high dysplasia. The majority of advanced adenomas were found in the left colon as compared to the right colon: 71.4% vs. 28.6%. p = 0.0008. CONCLUSIONS: In our study was obtained a 2.2% detection rate for advanced adenomas, most of them (71.4%) being located in the left colon. The dominant feature of advanced adenomas detected was the size > or = 10 mm (89.3% of cases).

RESUMO

The technical part of these Guidelines and Recommendations, produced under the auspices of EFSUMB, provides an introduction to the physical principles and technology on which all forms of current commercially available ultrasound elastography are based. A difference in shear modulus is the common underlying physical mechanism that provides tissue contrast in all elastograms. The relationship between the alternative technologies is considered in terms of the method used to take advantage of this. The practical advantages and disadvantages associated with each of the techniques are described, and guidance is provided on optimisation of scanning technique, image display, image interpretation and some of the known image artefacts.

RESUMO

The clinical part of these Guidelines and Recommendations produced under the auspices of the European Federation of Societies for Ultrasound in Medicine and Biology EFSUMB assesses the clinically used applications of all forms of elastography, stressing the evidence from meta-analyses and giving practical advice for their uses and interpretation. Diffuse liver disease forms the largest section, reflecting the wide experience with transient and shear wave elastography . Then follow the breast, thyroid, gastro-intestinal tract, endoscopic elastography, the prostate and the musculo-skeletal system using strain and shear wave elastography as appropriate. The document is intended to form a reference and to guide clinical users in a practical way.

RESUMO

UNLABELLED: The aim of the paper was to evaluate the national availability of colonoscopy and the quality parameters of this procedure in our country. MATERIAL AND METHOD: During a 6 months period (01.07- 31.12.2009), we performed a prospective multicenter study in which 76 centers were invited to respond to a questionnaire regarding colonoscopy, 39 centers agreeing to participate. We assessed: the number of colonoscopies, the number of total colonoscopies and the causes of incomplete colonoscopies. RESULTS: During the study period, 16,083 colonoscopies were performed, 12,294 (76.4%) of them total colonoscopies. In 1,191 cases, stenosis was the cause of incomplete colonoscopy. If we consider this an objective reason for an incomplete colonoscopy, there were 12,294 total colonoscopies (82.4%). Comparing university centers with non-university ones, the proportion of total colonoscopies was 10,400/12,475 (83.4%) vs. 1,894/2,417 (78.4%) (p less then 0.0001). However, comparing the present study with previous ones, performed in 2003 and 2007, the proportion of total colonoscopies increased from 70.5% to 76.9% and 82.4% respectively (2003 vs. 2007 p less then 0.0001; 2007 vs. 2009 p less then 0.0001), while the quality difference between university and non-university hospitals persisted. CONCLUSIONS: the quality of colonoscopy in Romania increased in the last 5 years, while the quality difference between university and non-university hospitals persisted.

RESUMO

BACKGROUND: Current polypectomy practices are highly variable. Endoscopists report increased size, nonpolypoid lesion type and unfavorable position as characteristic of difficult polypectomies. We studied reported difficult colonic polypectomies to determine polyp-related and operator-dependent factors influencing complication rates. PATIENTS AND METHODS: We conducted an international multicenter observational prospective study of difficult colonic polypectomies. Endoscopists reported difficult cases of colonic polypectomies, techniques and complication rates. Per-polyp and per-endoscopist analyses were performed. RESULTS: Ninety procedures were reported at 4 participating centers by 19 endoscopists. 43% of the lesions were pedunculated, 39% were sessile and 18% were flat. Lesion size ranged between 5-60 mm. Bleeding occurred in 18 out of 90 procedures (17 immediate, 1 delayed); no perforations were reported. Bleeding rate was independent of patient age or sex, polyp type, size and histology or resection method. Procedures were deemed difficult due to polyp size (37/90), unfavorable position (23/90), bleeding risk (12/90), lesion type (12/90) or other reasons (6/90) with no statistically significant difference between expert and beginner endoscopists (p = 0.14). CONCLUSION: Difficult colonic polypectomies are unpredictable with a complication rate independent of polyp type or size. There was no difference between experts and beginners with regard to technical aspects of resection or complication rates.

RESUMO

Colorectal cancer represents the third cause of cancer. Since its detection in due time is important resolution, appropriate monitoring is mandatory. The present study deals with the relationship between colorectal cancer and renal function, as well as other associated risk factors. Chronic kidney disease (CKD) represents a risk factor of cancer, both in non-dialysed patients and especially in dialysed patients and in patients with renal transplant. It can get aggravated with cancer in general and particularly with colorectal cancer, partly related to the toxins that cannot be appropriately eliminated because of renal functional disturbances. At the same time, immunosuppressive therapy used for treating glomerular or secondary nephropathies represents an important risk factor of cancer. Some patients with colorectal cancer were found to present also impaired renal function, a fact whose significance is still little known. The object of the present paper is an analysis of the case records of a clinic of gastroenterology on the relationship between colorectal cancer and renal functional impairment. We found in the patients with colorectal cancer under study a glomerular filtration rate (GFR calculated with the EPI formula) of < 60 ml/min/1.73m2 in 31/180 patients, respectively 17.22% of the cases, a value that is similar to that in specialised literature. We also analysed associated risk factors that could be related to renal function impairment in these patients: age, gender, anaemia, diabetes mellitus and hypertension. These could represent, together with the colorectal cancer of the investigated patients, risk factors affecting on the one hand renal function, and on the other hand, potentially increasing the risk of cancer. Correction of these risk factors would have beneficial effects on patients. The relationship between renal functional impairment, respectively CKD, and colorectal cancer is to be regarded from the point of view of complex reciprocity: the impairment of the renal function is a factor of risk of colorectal cancer and colorectal cancer can influence renal function of these patients. This report of reciprocity based on important pathogenic mechanisms also interrelates with factors of risk consecutive to both renal function impairment and colorectal cancer.

RESUMO

Liver Biopsy was considered the "gold standard" for severity assessment in chronic hepatitis for a very long time. In recent years, non invasive methods were developed in order to replace it. Among them ultrasound based elastographic methods: Transient Elastography (already validated and replacing liver biopsy in some countries), Real Time Tissue Elastography and Acoustic Radiation Force Impulse Elastography (currently under evaluation) and Shear Wave Elastography (the newest one). As an alternative to liver biopsy, the development of all these non invasive methods for dynamic evaluation of liver fibrosis will decrease the need for LB, making clinical care safer and more convenient for patients with liver diseases.

RESUMO

Acoustic Radiation Force Impulse (ARFI) imaging is a novel ultrasound-based elastography method that is integrated in a conventional ultrasound machine enabling the exact localization of measurement site. It might present an alternative method to transient elastography for the noninvasive assessment of liver fibrosis. At present, studies with small patient population have shown promising results. A systematic review and meta-analysis of pooled patient data were performed to evaluate the overall performance of ARFI for the staging of liver fibrosis. Literature databases were searched up to 10/2010. The authors of the original publication were contacted, and the original patient data were requested. A meta-analysis was performed using a random effect meta-analytic method for diagnostic tests. In addition, available data comparing ARFI with FibroScan with the DeLong test were evaluated. Literature search yielded nine full-paper publications evaluating ARFI while using liver biopsy as reference method. Original patient data were available from eight studies including 518 patients. The mean diagnostic accuracy of ARFI expressed as areas under ROC curves (AUROC) was 0.87 for the diagnosis of significant fibrosis (F ≥ 2), 0.91 for the diagnosis of severe fibrosis (F ≥ 3), and 0.93 for the diagnosis of cirrhosis. ARFI can be performed with good diagnostic accuracy for the noninvasive staging of liver fibrosis.

RESUMO

PURPOSE: To evaluate and compare the values of thyroid tissue elasticity in subjects without known thyroid pathology, in patients with Graves' disease and with chronic autoimmune thyroiditis (CAT). PATIENTS AND METHODS: We performed a prospective study that included 74 subjects, 23 without thyroid pathology, 29 with Graves' disease and 22 with CAT (diagnosed by specific tests). In all patients, 10 elastographic measurements were performed in the right thyroid lobe (RTL) and 10 in the left thyroid lobe (LTL) using a 2-6 MHz convex probe. Median values were calculated for each thyroid lobe, measured in meters/second (m/sec). We calculated a mean ARFI value from measurements made in the RTL and LTL. RESULTS: Thyroid stiffness was statistically significant lower in normal subjects vs. those with Graves' disease (2.07±0.44 m/sec vs. 2.82±0.47 m/sec, p<0.001) and with CAT (2.07±0.44 m/sec vs. 2.49±0.48 m/sec, p=0.004). We also found a statistically significant difference between subjects without thyroid pathology and those with autoimmune thyroid pathology (Graves' disease and CAT) (2.07±0.44 m/sec vs. 2.68±0.50 m/sec, p<0.001). CONCLUSION: ARFI seems to be a useful method for the evaluation of diffuse thyroid gland pathology and is able to predict with sufficient accuracy the presence of thyroid diffuse diseases (AUROC=0.80).

RESUMO

The study assesses the presence of asymptomatic urinary anomalies in patients with inflammatory bowel disease. Asymptomatic urinary anomalies are mainly due to glomerular nephritis, they being one of the forms of its manifestation, together with chronic nephrotic and nephritic syndromes. We identified urinary anomalies in 18 patients (20%) with bowel inflammatory disease that consisted of haematuria in 8 (9%) patients, isolated proteinuria in 5 (6%) patients and haematuria associated with proteinuria in 5 (6%) patients. Asymptomatic urinary anomalies were more frequent in patients with the Crohn disease than in those with ulcerative colitis. We identified RFG under 60ml/min in 4 patients with asymptomatic urinary anomalies. It is very easy to evaluate asymptomatic urinary anomalies with dipstick. This method is also required in current practice for patients with urinary anomalies for identifying the glomerular disease that might have caused them. One must take into consideration differential diagnosis with other diseases that can manifest themselves with proteinuria or isolated proteinuria. One must also take into account the fact that urinary anomalies may also be related to administration of 5-aminosalicylates.

RESUMO

PURPOSE: To compare two methods of noninvasive assessment: transient elastography (TE) and acoustic radiation force impulse elastography (ARFI). PATIENTS AND METHODS: Our study included 114 subjects: 38 healthy volunteers, (considered to have no fibrosis - F 0) and 76 patients with chronic liver disease: 53 who had undergone liver biopsy (LB) (7 with F 1, 24 with F 2, 22 with F 3 Metavir) and 23 previously diagnosed with cirrhosis (F4 Metavir). In each patient we performed a liver stiffness measurement by means of TE and ARFI. ARFI (shear wave velocity quantification) was performed at 3 points: at 0 - 1 cm, at 1 - 2 cm and at 2 - 3 cm under the capsule. For each depth, 5 valid measurements were made, and a median value was calculated, measured in m/sec. RESULTS: A direct, strong, linear correlation (Spearman rho = 0.848) was found between TE and the stage of fibrosis (p < 0.001). A significant, direct correlation was found between ARFI measurements made 1 - 2 cm and 2 - 3 cm below the liver capsule and the severity of fibrosis (rho = 0.675 and 0.714 respectively). The subcapsularly measured ARFI values showed a poor correlation with fibrosis (rho = 0.469). The best test for predicting significant fibrosis (F ≥ 2) was TE, with the area under receiver-operating characteristic curve (AUROC) 0.908, significantly larger than the AUROCs for ARFI. If only ARFI is considered, measurements made 1 - 2 and 2 - 3 cm below the capsule have the best predictive value, with AUROCs not significantly different from each other (0.767 and 0.731, respectively). For predicting fibrosis (F > 0), TE had the best predictive value: optimized cut-off 5.65 kPa (AUROC -0.898). For ARFI, the cut-offs were: 1.4 m/sec, AUROC -0.747 (1 - 2 cm), and 1.26 m/sec AUROC -0.721 (2 - 3 cm). For predicting cirrhosis (F = 4 Metavir), the optimized cut-offs were: TE -12.9 kPa (AUROC -0.994); ARFI - 1.78 m/sec for measurements made 2 - 3 cm below the capsule, AUROC - 0.951. CONCLUSION: At present, liver elasticity evaluation by means of ARFI is not superior to TE for the assessment of liver fibrosis. For ARFI, the most reliable results are obtained if measurements are made 1 - 2 and 2 - 3 cm below the liver capsule. ARFI is an accurate test for the diagnosis of cirrhosis.
