Preventing Postendoscopic Mucosal Resection Bleeding of Large Nonpedunculated Colorectal Lesions.

The most common major adverse event of endoscopic mucosal resection (EMR) is clinically significant post-EMR bleeding (CSPEB), with an incidence of 6%-7% in large lesions. Repeat colonoscopy, blood transfusions, or other interventions are often needed. The associated direct costs are much higher than those of an uncomplicated EMR. In this review, we discuss the aspects related to CSPEB of large nonpedunculated polyps, such as risk factors, predictive models, and prophylactic measures, and we highlight evidence for preventive treatment options and explore new methods for bleeding prophylaxis. We also provide recommendations for steps that can be taken before, during, and after EMR to minimize bleeding risk. Finally, this review proposes future directions to reduce CSPEB incidence.

Prophylactic Clipping After Colorectal Endoscopic Resection Prevents Bleeding of Large, Proximal Polyps: Meta-analysis of Randomized Trials.

BACKGROUND & AIMS: The benefits of prophylactic clipping to prevent bleeding after polypectomy are unclear. We conducted an updated meta-analysis of randomized trials to assess the efficacy of clipping in preventing bleeding after polypectomy, overall and according to polyp size and location. METHODS: We searched the MEDLINE/PubMed, Embase, and Scopus databases for randomized trials that compared the effects of clipping vs not clipping to prevent bleeding after polypectomy. We performed a random-effects meta-analysis to generate pooled relative risks (RRs) with 95% CIs. Multilevel random-effects metaregression analysis was used to combine data on bleeding after polypectomy and estimate associations between rates of bleeding and polyp characteristics. RESULTS: We analyzed data from 9 trials, comprising 71897 colorectal lesions (22.5% 20 mm or larger; 49.2% with proximal location). Clipping, compared with no clipping, did not significantly reduce the overall risk of postpolypectomy bleeding (2.2% with clipping vs 3.3% with no clipping; RR, 0.69; 95% confidence interval [CI], 0.45-1.08; P = .072). Clipping significantly reduced risk of bleeding after removal of polyps that were 20 mm or larger (4.3% had bleeding after clipping vs 7.6% had bleeding with no clipping; RR, 0.51; 95% CI, 0.33-0.78; P = .020) or that were in a proximal location (3.0% had bleeding after clipping vs 6.2% had bleeding with no clipping; RR, 0.53; 95% CI, 0.35-0.81; P < .001). In multilevel metaregression analysis that adjusted for polyp size and location, prophylactic clipping was significantly associated with reduced risk of bleeding after removal of large proximal polyps (RR, 0.37; 95% CI, 0.22-0.61; P = .021) but not small proximal lesions (RR, 0.88; 95% CI, 0.48-1.62; P = .581). CONCLUSIONS: In a meta-analysis of randomized trials, we found that routine use of prophylactic clipping does not reduce risk of postpolypectomy bleeding overall. However, clipping appeared to reduce bleeding after removal of large (more than 20 mm) proximal lesions.

Clip Closure After Resection of Large Colorectal Lesions With Substantial Risk of Bleeding.

BACKGROUND & AIMS: It is not clear whether closure of mucosal defects with clips after colonic endoscopic mucosal resection (EMR) prevents delayed bleeding, although it seems to have no protective effects when risk is low. We performed a randomized trial to evaluate the efficacy of complete clip closure of large (≥2 cm) nonpedunculated colorectal lesions after EMR in patients with an estimated average or high risk of delayed bleeding. METHODS: We performed a single-blind trial at 11 hospitals in Spain from May 2016 through June 2018, including 235 consecutive patients who underwent EMR for large nonpedunculated colorectal lesions with an average or high risk of delayed bleeding (based on Spanish Endoscopy Society Endoscopic Resection Group score). Participants were randomly assigned to groups that received closure of the scar with 11-mm through-the-scope clips (treated, n = 119) or no clip (control, n = 116). The primary outcome was proportion of patients in each group with delayed bleeding, defined as evident hematochezia that required medical intervention within 15 days after colonoscopy. RESULTS: In the clip group, complete closure was achieved in 68 (57%) cases, with partial closure in 33 (28%) cases and failure to close in 18 (15%) cases. Delayed bleeding occurred in 14 (12.1%) patients in the control group and in 6 (5%) patients in the clip group (absolute risk difference, reduction of 7% in the clip group; 95% confidence interval, -14.7% to 0.3%). After completion of the clip closure, there was only 1 (1.5%) case of delayed bleeding (absolute risk difference, reduction of 10.6%; 95% confidence interval, -4.3% to 17.9%). CONCLUSIONS: In a randomized trial of patients with large nonpedunculated colorectal lesions undergoing EMR, we found that clip closure of mucosal defects in patients with a risk of bleeding can be a challenge, but also reduces delayed bleeding. Prevention of delayed bleeding required complete clip closure. ClinicalTrials.gov ID: NCT02765022.

Clinical validation of risk scoring systems to predict risk of delayed bleeding after EMR of large colorectal lesions.

BACKGROUND AND AIMS: The Endoscopic Resection Group of the Spanish Society of Endoscopy (GSEED-RE) model and the Australian Colonic Endoscopic Resection (ACER) model were proposed to predict delayed bleeding (DB) after EMR of large superficial colorectal lesions, but neither has been validated. We validated and updated these models. METHODS: A multicenter cohort study was performed in patients with nonpedunculated lesions ≥20 mm removed by EMR. We assessed the discrimination and calibration of the GSEED-RE and ACER models. Difficulty performing EMR was subjectively categorized as low, medium, or high. We created a new model, including factors associated with DB in 3 cohort studies. RESULTS: DB occurred in 45 of 1034 EMRs (4.5%); it was associated with proximal location (odds ratio [OR], 2.84; 95% confidence interval [CI], 1.31-6.16), antiplatelet agents (OR, 2.51; 95% CI, .99-6.34) or anticoagulants (OR, 4.54; 95% CI, 2.14-9.63), difficulty of EMR (OR, 3.23; 95% CI, 1.41-7.40), and comorbidity (OR, 2.11; 95% CI, .99-4.47). The GSEED-RE and ACER models did not accurately predict DB. Re-estimation and recalibration yielded acceptable results (GSEED-RE area under the curve [AUC], .64 [95% CI, .54-.74]; ACER AUC, .65 [95% CI, .57-.73]). We used lesion size, proximal location, comorbidity, and antiplatelet or anticoagulant therapy to generate a new model, the GSEED-RE2, which achieved higher AUC values (.69-.73; 95% CI, .59-.80) and exhibited lower susceptibility to changes among datasets. CONCLUSIONS: The updated GSEED-RE and ACER models achieved acceptable prediction levels of DB. The GSEED-RE2 model may achieve better prediction results and could be used to guide the management of patients after validation by other external groups.

Real-life chromoendoscopy for neoplasia detection and characterisation in long-standing IBD.

OBJECTIVE: Outside clinical trials, the effectiveness of chromoendoscopy (CE) for long-standing IBD surveillance is controversial. We aimed to assess the effectiveness of CE for neoplasia detection and characterisation, in real-life. DESIGN: From June 2012 to 2014, patients with IBD were prospectively included in a multicentre cohort study. Each colonic segment was evaluated with white light followed by 0.4% indigo carmine CE. Specific lesions' features were recorded. Optical diagnosis was assessed. Dysplasia detection rate between expert and non-expert endoscopists and learning curve were ascertained. RESULTS: Ninety-four (15.7%) dysplastic (1 cancer, 5 high-grade dysplasia, 88 low-grade dysplasia) and 503 (84.3%) non-dysplastic lesions were detected in 350 patients (47% female; mean disease duration: 17 years). Colonoscopies were performed with standard definition (41.5%) or high definition (58.5%). Dysplasia miss rate with white light was 40/94 (57.4% incremental yield for CE). CE-incremental detection yield for dysplasia was comparable between standard definition and high definition (51.5% vs 52.3%, p=0.30). Dysplasia detection rate was comparable between expert and non-expert (18.5% vs 13.1%, p=0.20). No significant learning curve was observed (8.2% vs 14.2%, p=0.46). Sensitivity, specificity, and positive and negative predictive values for dysplasia optical diagnosis were 70%, 90%, 58% and 94%, respectively. Endoscopic characteristics predictive of dysplasia were: proximal location, loss of innominate lines, polypoid morphology and Kudo pit pattern III-V. CONCLUSIONS: CE presents a high diagnostic yield for neoplasia detection, irrespectively of the technology and experience available in any centre. In vivo, CE optical diagnosis is highly accurate for ruling out dysplasia, especially in expert hands. Lesion characteristics can aid the endoscopist for in situ therapeutic decisions.

Endoscopic tattooing of colorectal neoplasms removed by laparoscopy: a proposal for selective marking.

BACKGROUND AND AIM: Preoperative endoscopic tattooing is an effective procedure to identify small intraoperative neoplasms. However, there are no defined criteria with regard to the indications for endoscopic tattooing of these lesions at the time of diagnosis. The aim of this study was to establish endoscopic criteria that allow the selection of patients who will need a tattoo during the diagnostic colonoscopy. METHODS: An ambispective study of patients undergoing laparoscopy due to a colorectal neoplasia who underwent endoscopic tattooing during the period from 2007-2013 and 2016-2017. According to the endoscopic description of the neoplasms, the classification was polypoid lesions, neoplasms occupying < 50% or ≥ 50% of the intestinal lumen and stenosing neoplasias. RESULTS: Tattooing of the lesion was performed in 120 patients and the same lesions were identified during surgery in 114 (95%) cases. Most of the neoplasias described as polypoids and neoplasias that occupied < 50% of the intestinal lumen were not visualized during surgery and therefore required a tattoo (33 of 42 and 18 of 26 respectively, p = 0.0001, X2). On the other hand, stenosing lesions or neoplasias occupying ≥ 50% of the intestinal lumen were mostly identified during surgery (15 of 15 and 36 of 37 respectively, p = 0.0001, X2) without the need for a tattoo. Overall, the identification of neoplasms according to established criteria was 98%. CONCLUSION: These results suggest that it is possible to establish endoscopic criteria that allow a successful selective tattooing during diagnostic endoscopy.

A Scoring System to Determine Risk of Delayed Bleeding After Endoscopic Mucosal Resection of Large Colorectal Lesions.

BACKGROUND & AIMS: After endoscopic mucosal resection (EMR) of colorectal lesions, delayed bleeding is the most common serious complication, but there are no guidelines for its prevention. We aimed to identify risk factors associated with delayed bleeding that required medical attention after discharge until day 15 and develop a scoring system to identify patients at risk. METHODS: We performed a prospective study of 1214 consecutive patients with nonpedunculated colorectal lesions 20 mm or larger treated by EMR (n = 1255) at 23 hospitals in Spain, from February 2013 through February 2015. Patients were examined 15 days after the procedure, and medical data were collected. We used the data to create a delayed bleeding scoring system, and assigned a weight to each risk factor based on the ß parameter from multivariate logistic regression analysis. Patients were classified as being at low, average, or high risk for delayed bleeding. RESULTS: Delayed bleeding occurred in 46 cases (3.7%, 95% confidence interval, 2.7%-4.9%). In multivariate analysis, factors associated with delayed bleeding included age ≥75 years (odds ratio [OR], 2.36; P < .01), American Society of Anesthesiologist classification scores of III or IV (OR, 1.90; P ≤ .05), aspirin use during EMR (OR, 3.16; P < .05), right-sided lesions (OR, 4.86; P < .01), lesion size ≥40 mm (OR, 1.91; P ≤ .05), and a mucosal gap not closed by hemoclips (OR, 3.63; P ≤ .01). We developed a risk scoring system based on these 6 variables that assigned patients to the low-risk (score, 0-3), average-risk (score, 4-7), or high-risk (score, 8-10) categories with a receiver operating characteristic curve of 0.77 (95% confidence interval, 0.70-0.83). In these groups, the probabilities of delayed bleeding were 0.6%, 5.5%, and 40%, respectively. CONCLUSIONS: The risk of delayed bleeding after EMR of large colorectal lesions is 3.7%. We developed a risk scoring system based on 6 factors that determined the risk for delayed bleeding (receiver operating characteristic curve, 0.77). The factors most strongly associated with delayed bleeding were right-sided lesions, aspirin use, and mucosal defects not closed by hemoclips. Patients considered to be high risk (score, 8-10) had a 40% probability of delayed bleeding.

Peginterferon alpha-2a and ribavirin in patients with hepatitis C virus genotype 1 infection with persistently normal alanine aminotransferase levels.

BACKGROUND AND AIM: To evaluate the efficacy and safety of peginterferon α-2a plus ribavirin at standard doses in patients with hepatitis C virus (HVC) genotype 1 infection with persistently normal alanine aminotransferase (ALT) levels. METHODS: Patients aged 18 to 65 years were included in this observational, prospective study if they had evidence of a HCV genotype 1 infection. The serum HCV RNA concentration was determined at baseline and week 12. A qualitative HCV RNA test was performed at baseline and at weeks 48 and 72. Liver function tests were performed at each study visit. The primary efficacy measure was the sustained virological response in the intention-to-treat population. Logistic regression analyses were also performed to explore predictors of virological response. RESULTS: A sustained virological response was observed in 100 of the 175 patients (57%). An early virological response and end-of-treatment response were seen in 159 patients (91%) and 133 patients (76%), respectively. Thirty-seven of the 122 evaluable patients for this outcome (30%) showed a rapid virological response. A higher viral load was a significant predictor for a lack of rapid virological response and lack of sustained virological response. There were not any unexpected safety or tolerability findings. CONCLUSIONS: Our study suggests that the efficacy of the combination of peginterferon α-2a and ribavirin in patients with HCV genotype 1 infection and normal ALT levels is at least similar to that reported in patients with elevated ALT levels.

Long-term clinical course of decompensated alcoholic cirrhosis: a prospective study of 165 patients.

BACKGROUND: Prognosis of decompensated alcoholic cirrhosis is based mainly on studies that included patients with different severities of liver disease and did not recognize either hepatitis C virus epidemic or changes in clinical management of cirrhosis. AIM: To define the long-term course after the first hepatic decompensation in alcoholic cirrhosis. METHODS: Prospective inclusion at the start point of decompensated cirrhosis of 165 consecutive patients with alcoholic cirrhosis without known hepatocellular carcinoma hospitalized from January 1998 to December 2001 was made. Follow-up was maintained until death or the end of the observation period (April 1, 2010). RESULTS: The patients were followed for 835.75 patient years. Median age was 56 years (95% confidence interval: 54-58). Baseline Child-Pugh score was 9 (95% CI: 8-9), and model for end-stage liver disease (MELD) was 13.8 (95% CI: 12.5-14.7). Ascites was the most frequent first decompensation (51%). During follow-up, 99 (60%) patients were abstinent, hepatocellular carcinoma developed in 18 (11%) patients, and 116 patients died (70%). Median overall survival was 61 months (95% CI: 48-74). Median survival probability after onset of hepatic encephalopathy (HE) was only 14 months (95% CI: 5-23). Age, baseline MELD, albumin, development of HE, and persistence of alcohol use were independently correlated with mortality. CONCLUSIONS: Patients with alcoholic cirrhosis show a high frequency of complications. The low mortality rate in our cohort of patients probably reflects the improvement in the management of patients with cirrhosis; it is mainly influenced by baseline MELD, age, HE development, and continued abstinence. Patients who develop HE should be considered for hepatic transplantation.

[Cost of screening for hepatocarcinoma in patients with cirrhosis: a prospective study]. / Coste del cribado del hepatocarcinoma en pacientes cirróticos: un estudio prospectivo.

INTRODUCTION: Current clinical guidelines recommend biannual screening for hepatocarcinoma in cirrhotic patients; however, the cost of this preventive activity is unknown. OBJECTIVE: To determine the cost of ultrasound screening for hepatocarcinoma in patients with cirrhosis. PATIENTS AND METHOD: Data on patients diagnosed with liver cirrhosis in a population of 245,042 inhabitants were prospectively gathered. The screening tests performed and cases of hepatocarcinoma diagnosed during the annual follow-up were included in the analysis. The cost of these tests was calculated based on the tariffs paid by insurance companies for health coverage of civil servants. RESULTS: In 2009, there were 374 patients with cirrhosis; of these, 99 were aged > 80 years, with a performance status of >2 or associated comorbidities. During the annual follow-up, the remaining patients underwent a total of 602 visits (abdominal ultrasound, blood test), four contrast-enhanced computed tomography scans, nine magnetic resonance scans, two scintigraphies, four aspiration biopsies, four radiographs and six contrast ultrasound scans. In our environment, the total estimated cost of these procedures was 37,946 €, indicating that the cost of a screening program for hepatocellular carcinoma according to the above-mentioned selection criteria is 0.155 € per inhabitant/year. If only cirrhotic patients suitable for screening are included, the annual cost of screening is 138 € per patient. CONCLUSION: The cost of an ultrasound screening program for hepatocarcinoma is 0.155 € per inhabitant/year. These data should be taken into account when considering population-based screening programs.

Incidence and prognosis of different types of functional renal failure in cirrhotic patients with ascites.

BACKGROUND & AIMS: Hepatorenal syndrome is a well-characterized type of terminal renal failure that occurs in patients with cirrhosis with ascites. Information about other types of functional renal failure in these patients is scarce. We assessed the incidence and prognosis of different types of functional renal failure in cirrhotic patients with ascites and investigated prognostic factors for these disorders. METHODS: Consecutive cirrhotic patients (n = 263) were followed for 41 +/- 3 months after their first incidence of ascites. Three types of functional renal failure were considered: pre-renal failure (when renal failure was associated with a depletion of intravascular volume), renal failure induced by infection that did not result in hepatorenal syndrome, and hepatorenal syndrome. RESULTS: During the follow-up period, 129 (49%) patients developed some type of functional renal failure. The most frequent was pre-renal failure (27.4%), followed by renal failure induced by infection (14.1%), and then hepatorenal syndrome (7.6%). The 1-year probability of developing the first episode of any functional renal failure was 23.6%. The independent predictors of functional renal failure development were baseline age, Child-Pugh score, and serum creatinine. Although the 1-year probability of survival was 91% in patients without renal failure, it decreased to 46.9% in those patients who developed any functional renal failure (P = .0001). CONCLUSIONS: Approximately 50% of the cirrhotic patients with ascites developed some type of functional renal failure during the follow-up period; renal failure was associated with worse prognosis. Efforts should be made to prevent renal failure in cirrhotic patients with ascites.

Neurotoxoplasmosis con presentación imagenológica atípica / Atypical imaging presentation of neurotoxoplasmosis

La toxoplasmosis cerebral o neurotoxoplasmosis es una de las infecciones por agentes oportunistas más frecuentes en pacientes infectados por virus de inmunodeficiencia humana (VIH) y se relaciona con inmunodeficiencia severa. En estos pacientes causa lesiones neurológicas de alto grado e incluso la muerte. Suele aparecer como múltiples focos de lesión de predominio gangliobasal y con realce anular. Se presenta un caso clínico de neurotoxoplasmosis en paciente VIH con un patrón radiológico poco frecuente.

Cerebral toxoplasmosis or neurotoxoplasmosis is one of the most frequent infections by opportunistic agents in HIV-infected patients and is associated with severe immunodeficiency. In these patients, it causes high-grade neurological lesions and even death. It usually appears as multiple foci of lesions with gangliobasal predominance and annular enhancement. We present a clinical case of neurotoxoplasmosis in a HIV patient with an unusual radiological pattern.

Presence of depressive symptoms in medical students in a Mexican public university / Presencia de síntomas depresivos en estudiantes de medicina en una universidad pública de México

Abstract Introduction During their professional training, medical students are subject to diverse stress-causing factors such as academic demands and a highly competitive environment which may threaten their mental health. Objective Identify the presence of depressive symptoms in medical students in a public university in Mexico. Method Descriptive cross-sectional study of a random sample of 203 medical students at the Universidad Autónoma de Baja California from February to April 2018. The PHQ - 9 scale was used, and a cut-off score of ≥ 10 was employed as positive for depressive symptoms. Basic descriptive statistics were utilized to analyze sociodemographic variables such as gender, academic advancement, stage of training (basic science vs. clinical), and the prevalence of the five different categories of the scale. Results Of the medical students surveyed, 20.2% were found positive for depressive symptoms and 7.9% (16) had severe or moderately severe symptoms. Female gender increased the risk of presenting symptoms (OR = 3.5, 95% CI [1.6, 7.6]). Discussion Despite the fact that the prevalence of depressive symptoms encountered was similar to that reported worldwide, it is troubling that one fifth of the surveyed students presented depressive symptoms. These results may justify implementation of preventive strategies by academic authorities to improve student mental health, and maybe even for early detection of risk of major depressive disorder.

Resumen Introducción Durante su formación profesional, los estudiantes de medicina están sometidos a diversos factores generadores de estrés como la exigencia académica y un entorno altamente competitivo, lo cual podría llegar a ser adverso para su salud mental. Objetivo Identificar la presencia de síntomas depresivos en estudiantes de medicina de una universidad pública mexicana. Método Estudio transversal, descriptivo, que se realizó con una muestra aleatoria de 203 estudiantes de medicina de la Universidad Autónoma de Baja California de febrero a abril de 2018. Se utilizó el cuestionario PHQ - 9 tomando el punto de corte ≥ 10 como positivo para síntomas depresivos. Para el análisis de datos se utilizó estadística descriptiva; se estimaron proporciones de las variables sociodemográficas como género, semestre cursado, etapa básica o disciplinar y prevalencias de las diferentes categorías de la escala. Resultados Se encontró una prevalencia de 20.2% de estudiantes de medicina con presencia de síntomas depresivos y el 7.9% reportó síntomas graves o moderadamente graves. Pertenecer al género femenino resultó ser un factor que incrementa las posibilidades de presentar síntomas depresivos (OR = 3.5, IC 95% [1.6, 7.6]). Discusión A pesar de que la prevalencia de síntomas depresivos encontrada fue similar a lo reportado a nivel mundial, preocupa que una quinta parte de los encuestados presentaran síntomas depresivos. Estos resultados podrían permitir justificar a las autoridades académicas y a la comunidad estudiantil la implementación de estrategias preventivas para el mejoramiento de la salud mental de los estudiantes e incluso quizá detectar en forma temprana el riesgo de presentar un trastorno depresivo mayor.

Objetivo: Comparar la rapidez para obtener datos de frecuencia cardiaca neonatal entre el monitoreo electrocardiográfico y la oximetría de pulso en neonatos. Resultados: El tiempo promedio para obtener una lectura de frecuencia cardiaca confiable usando el electrocardiograma fue en promedio de 18,8 segundos, con una mediana de 13. El tiempo promedio para obtener una lectura estable de la frecuencia cardiaca usando pulso-oximetría fue de 27,8 segundos con mediana de 26 segundos. Conclusión: En la medición de la frecuencia cardíaca, el electrocardiograma fue 33% más rápido que el pulso-oxímetro

Objective: To compare the speed to obtain neonatal heart rate data between electrocardiographic monitoring and pulse oximetry in neonates. Methodology: The study was conducted in twenty-seven (27) neonates born by caesarean section; the heart rate was measured by pulse oximetry and electro-cardiographic monitoring. In each neonate, data was collected for a minimum of three minutes and the time in which a reliable heart rate was recorded was established. The study was approved by the Ethics Committee of the participating entity and the informed consent of the involved parents was obtained. Results: the average time to obtain a reliable heart rate reading using the electrocardiogram was, on average, 18.8 seconds, with a median of 13. The average time to obtain a reliable reading of the heart rate using pulse oximetry was 27.8 seconds with a median of 26. Conclusion: In the measurement of the heart rate, the electrocardiogram was 33% faster than the pulse-oximeter.

Probability of liver cancer and survival in HCV-related or alcoholic-decompensated cirrhosis. A study of 377 patients.

BACKGROUND: Although chronic alcohol intake and chronic hepatitis C may progress to cirrhosis and hepatocellular carcinoma (HCC), few data are available about survival and probability of developing HCC in decompensated cirrhosis of both aetiologies. METHODS: This study identified factors related with probability of developing HCC and survival in a cohort of 377 consecutive patients with decompensated HCV-related cirrhosis (200 cases) or alcoholic cirrhosis (177 cases) without known HCC, hospitalized for their first hepatic decompensation, as well as to evaluate differences between both aetiologies. Patients were followed for a mean period of 39 +/- 2 months. RESULTS: During follow-up, 42 patients (11.1%) developed HCC (16.5% vs 5.1%) in groups HCV and alcohol, respectively; p = 0.0008), and 131 patients (34.7%) died (42% vs 26.6% in groups HCV and alcohol, respectively; p = 0.002). Age and HCV-cirrhosis were independently related to HCC development, while baseline age and Child-Turcotte-Pugh score were independently correlated with survival. CONCLUSION: Survival in decompensated HCV-related or alcoholic cirrhosis is influenced by age and baseline Child-Turcotte-Pugh score, without differences in cirrhosis aetiology. The risk of developing HCC is greater in HCV-related cirrhosis than in alcoholic cirrhosis.

Natural history of decompensated hepatitis C virus-related cirrhosis. A study of 200 patients.

BACKGROUND/AIMS: Since few data are available concerning the clinical course of decompensated hepatitis C virus (HCV)-related cirrhosis, the aim of the present study was to define the natural long-term course after the first hepatic decompensation. METHODS: Cohort of 200 consecutive patients with HCV-related cirrhosis, and without known hepatocellular carcinoma (HCC), hospitalized for the first hepatic decompensation. RESULTS: Ascites was the most frequent first decompensation (48%), followed by portal hypertensive gastrointestinal bleeding (PHGB) (32.5%), severe bacterial infection (BI) (14.5%) and hepatic encephalopathy (HE) (5%). During follow-up (34+/-2 months) there were 519 readmissions, HCC developed in 33 (16.5%) patients, and death occurred in 85 patients (42.5%). The probability of survival after diagnosis of decompensated cirrhosis was 81.8 and 50.8% at 1 and 5 years, respectively. HE and/or ascites as the first hepatic decompensation, baseline Child-Pugh score, age, and presence of more than one decompensation during follow-up were independently correlated with survival. CONCLUSIONS: Once decompensated HCV-related cirrhosis was established, patients showed not only a very high frequency of readmissions, but also developed decompensations different from the initial one. These results contribute to defining the natural course and prognosis of decompensated HCV-related cirrhosis.
