HEPATITIS C VIRUS SCREENING AND LINKAGE TO CARE IN MENTAL HEALTH UNITS: AN OPPORTUNITY FOR HCV ELIMINATION.

Hepatitis C Virus (HCV) affects approximately 71 million people infected, with 1.75 million people being diagnosed each year, according to the World Health Organization (WHO) estimates. HCV infection leads to cirrhosis, hepatocellular carcinoma (HCC), liver failure and death.

Kinetics of emergence of liver complications in hepatitis C virus infected patients and advanced fibrosis, with and without HIV-coinfection, after sustained virological response.

OBJECTIVE: There is scarce available evidence on the distribution over time of liver complications emergence in hepatitis C virus (HCV)-infected patients who achieve sustained virological response (SVR) with direct-acting antiviral (DAA)-based therapy. Therefore, we aimed at describing the kinetics of liver-related events appearance in this setting. DESIGN: A multicentric prospective cohort study. METHODS: HCV-monoinfected and HIV/HCV-coinfected patients from GEHEP-011 cohort, whose inclusion criteria were had achieved SVR with DAA-based therapy; liver stiffness prior to starting treatment at least 9.5 kPa; and available liver stiffness measurement at SVR. SVR was considered as the baseline time-point. RESULTS: One thousand and thirty-five patients were included, 664 (64%) coinfected with HIV. Before DAA-based therapy, 63 (6.1%) individuals showed decompensated cirrhosis. After SVR, 51 (4.9%) patients developed liver complications. Median (Q1-Q3) time to the emergence of hepatic events was hepatic encephalopathy 11 (7-24) months, ascites 14 (6-29) months, hepatocellular carcinoma (HCC) 17 (11-42) months and portal hypertension gastrointestinal bleeding (PHGB) 28 (22-38) months (P = 0.152). We define two profiles of liver complications: those emerging earlier (encephalopathy and ascites) and, those occurring continuously during the follow-up (HCC, PHGB) [median (Q1-Q3) time to emergence 12.7 (6.6-28.2) months vs. 25.4 (12.5-41.53) months, respectively (P = 0.026)]. CONCLUSION: The vast majority of HCV-infected patients who develop liver complications after reaching SVR with DAA do it within 3 years after SVR time-point. Specifically, hepatic encephalopathy and ascites do not usually emerge after this period. Conversely, HCC and PHGB may occur in longer term. It is critical to identify patients at risk of developing hepatic events to continue performing surveillance for them.

Liver Stiffness-Based Strategies Predict Absence of Variceal Bleeding in Cirrhotic Hepatitis C Virus-Infected Patients With and Without Human Immunodeficiency Virus Coinfection After Sustained Virological Response.

BACKGROUND: In the setting of hepatitis C virus (HCV) active infection, liver stiffness (LS)-based strategies identify patients with low risk of developing esophageal variceal bleeding (VB) episodes, in whom unnecessary upper esophagogastroduodenoscopy (UGE) screening can be safely avoided. However, after sustained virological response (SVR), data on the accuracy of the criteria predicting this outcome in HCV-infected patients with cirrhosis, with or without human immunodeficiency virus (HIV) coinfection, are very limited. METHODS: This was a multicenter prospective cohort study, where HCV-monoinfected patients and HIV/HCV-coinfected individuals were included if they had (1) SVR with direct-acting antiviral-based therapy; (2) LS ≥9.5 kPa previous to treatment; and (3) LS measurement at the SVR time-point ≥14 kPa. Diagnostic accuracy of HEPAVIR, expanded Baveno VI, and HIV cirrhosis criteria, at the time of SVR, was evaluated. Missed VB episodes, negative predictive values (NPVs), and number of spared UGEs were specifically assessed. RESULTS: Four hundred thirty-five patients were included, 284 (65%) coinfected with HIV. Seven (1.6%) patients developed a first episode of VB after SVR. In patients without a previous VB episode, HEPAVIR, expanded Baveno VI and HIV cirrhosis criteria achieved NPV for first VB episode after SVR of 99.5% (95% confidence interval [CI], 97.1%-100%), 100% (95% CI 97.8%-100%), and 100% (95% CI 98%-100%) while sparing 45%, 39%, and 44% of UGEs, respectively. When considering HIV coinfection, the performance of the 3 criteria was similar, both in HCV-monoinfected and HIV/HCV-coinfected individuals. CONCLUSIONS: After SVR, predictive LS-based strategies accurately identify HCV-infected patients, HIV coinfected or not, with low risk of developing VB during follow-up. In these specific patients, using HIV cirrhosis criteria maximize the number of spared UGEs while missing no VB episode.

Human Immunodeficiency Virus (HIV) Infection Is Associated With Lower Risk of Hepatocellular Carcinoma After Sustained Virological Response to Direct-acting Antivirals in Hepatitis C Infected Patients With Advanced Fibrosis.

BACKGROUND: The aim of this study was to assess the impact of human immunodeficiency virus (HIV) infection on the risk of developing hepatocellular carcinoma (HCC) in patients infected with hepatitis C virus (HCV) who achieve sustained virological response (SVR) with direct-acting antiviral (DAA). METHODS: Multisite prospective cohort study, where HCV-monoinfected patients and HIV/HCV-coinfected individuals were included if they met: (1) SVR with DAA-based combination; (2) liver stiffness (LS) ≥9.5 kPa previous to treatment; (3) LS measurement at the SVR time-point. The main endpoint was the occurrence of HCC. Propensity score (PS) was calculated to address potential confounders due to unbalanced distribution of baseline characteristics of HIV/HCV-coinfected and HCV-monoinfected patients. RESULTS: In total, 1035 HCV-infected patients were included, 667 (64%) coinfected with HIV. After a median (Q1-Q3) follow-up time of 43 (31-49) months, 19 (1.8%) patients developed HCC (11 [3.0%]; HCV-monoinfected, 8[1.2%]; HIV/HCV-coinfected individuals; P = .013). In the multivariable analysis, HIV coinfection was associated with a lower adjusted risk of developing HCC (subhazard ratio [sHR] = 0.27, 95% confidence interval [CI]: .08-.90; P = .034). Predictors of HCC emergence were: HCV genotype 3 (sHR = 7.9, 95% CI: 2.5-24.9; P < .001), MELD score at SVR >10 (sHR = 1.37, 95% CI: 1.01-1.86; P = .043) and LS value at SVR (sHR = 1.03, 95% CI: 1.01-1.06, for 1 kPa increase; P = .011). Using inverse probability weighting method on the PS, HIV-infected patients had a lower risk of HCC (powered HR = 0.33, 95% CI: .11-.85). CONCLUSIONS: Among HCV-infected patients with advanced fibrosis, who achieve SVR with DAA, HIV coinfection seems to be associated with a lower risk of HCC occurrence. The underlying causes for this finding need to be investigated.

Impact of HIV on the survival of hepatocellular carcinoma in hepatitis C virus-infected patients.

BACKGROUND: Previous studies have suggested that hepatocellular carcinoma (HCC) has an aggressive presentation and a shorter survival in people with HIV (PWH). This could be due to later diagnosis or lower rates of HCC treatment, and not to HIV infection itself. AIM: :: To assess the impact of HIV on HCC survival in hepatitis C virus (HCV)-infected patients. METHODS: Multicenter cohort study (1999-2018) of 342 and 135 HCC cases diagnosed in HIV/HCV-infected and HCV-monoinfected patients. Survival after HCC diagnosis and its predictors were assessed. RESULTS: HCC was at Barcelona-Clinic Liver-Cancer (BCLC) stage 0/A in 114 (33%) HIV/HCV-coinfected and in 76 (56%) HCV-monoinfected individuals (P < 0.001). Of them, 97 (85%) and 50 (68%) underwent curative therapies (P = 0.001). After a median (Q1-Q3) follow-up of 11 (3-31) months, 334 (70%) patients died. Overall 1 and 3-year survival was 50 and 31% in PWH and 69 and 34% in those without HIV (P = 0.16). Among those diagnosed at BCLC stage 0/A, 1 and 3-year survival was 94 and 66% in PWH whereas it was 90 and 54% in HIV-negative patients (P = 0.006). Independent predictors of mortality were age, BCLC stage and α-fetoprotein levels. HIV infection was not independently associated with mortality [adjusted hazard ratio (AHR) 1.57; 95% confidence interval: 0.88-2.78; P = 0.12]. CONCLUSION: HIV coinfection has no impact on the survival after the diagnosis of HCC in HCV-infected patients. Although overall mortality is higher in HIV/HCV-coinfected patients, this seem to be related with lower rates of early diagnosis HCC in HIV-infected patients and not with HIV infection itself or a lower access to HCC therapy.

Eficacia de la técnica Halsted II en pacientes geriátricos con hernia inguinal / Efficacy of the Halsted II technique in geriatric patients with inguinal hernia

RESUMEN Fundamento: el tratamiento ideal de la hernia inguinal en pacientes geriátricos siempre ha sido un reto. Objetivo: evaluar la eficacia de la técnica de Halsted II en pacientes geriátricos con hernia inguinal. Métodos: se realizó un estudio descriptivo transversal, con el objetivo de demostrar la eficacia de la técnica de Halsted II en pacientes geriátricos con hernia inguinal en el Servicio de Cirugía General del Hospital Militar Clínico Quirúrgico Docente Octavio de la Concepción y de la Pedraja, Camagüey desde julio de 2014 a julio 2017. El universo estuvo constituido por 84 adultos mayores con hernia inguinal y la muestra fue de 72 pacientes. Resultados: en el estudio predominaron los hombres caucásicos entre 60 y 74 años de edad, con hernia indirecta con aumento del anillo interno, además del tabaquismo y las enfermedades pulmonares obstructivas crónicas. La infección de la herida quirúrgica fue la complicación temprana más frecuente, sin ser significativo el número de rechazo al material de sutura no absorbible y recurrencia de la hernia. Conclusiones: la hernia inguinal en el adulto mayor, es más frecuente en los hombres blancos en edades comprendidas entre los 60 y 74 años. El tabaquismo y las enfermedades pulmonares obstructivas crónicas son factores de riesgo para padecer de hernia inguinal y a su vez son agentes asociados a la menor eficacia de la técnica. La herniorrafía de Halsted II es una técnica segura y eficiente en el adulto mayor, con escasa recurrencia y complicaciones postoperatorias.

ABSTRACT Background: the ideal treatment of inguinal hernia in geriatric patients remains a challenge. Objective: to evaluate the effectiveness of the Halsted II technique in geriatric patients with inguinal hernia. Methods: a cross-sectional descriptive study was carried out, with the objective of demonstrating the effectiveness of the Halsted II technique in geriatric patients with inguinal hernia in the General Surgery Service of the Teaching Surgical Clinical Military Hospital Octavio de la Concepción y La Pedraja, Camagüey, in the period from July 2014 to July 2017. The universe consisted of 84 older adults with inguinal hernia and the sample was 72 patients. Results: the study was dominated by Caucasian men between 60 and 74 years of age, with indirect hernia with increased internal ring, in addition to smoking and chronic obstructive pulmonary diseases. Infection of the surgical wound was the most frequent early complication, without being significant the number of rejection to the non-absorbable suture material and recurrence of the hernia. Conclusions: inguinal hernia in the elderly is more common in white men between the ages of 60 and 74. Smoking and chronic obstructive pulmonary diseases are risk factors for suffering from inguinal hernia and in turn are agents associated with the lower efficacy of the technique. Halsted II herniorrhaphy is a safe and efficient technique in the elderly, with low recurrence and postoperative complications.

Using machine learning methods to determine a typology of patients with HIV-HCV infection to be treated with antivirals.

Several European countries have established criteria for prioritising initiation of treatment in patients infected with the hepatitis C virus (HCV) by grouping patients according to clinical characteristics. Based on neural network techniques, our objective was to identify those factors for HIV/HCV co-infected patients (to which clinicians have given careful consideration before treatment uptake) that have not being included among the prioritisation criteria. This study was based on the Spanish HERACLES cohort (NCT02511496) (April-September 2015, 2940 patients) and involved application of different neural network models with different basis functions (product-unit, sigmoid unit and radial basis function neural networks) for automatic classification of patients for treatment. An evolutionary algorithm was used to determine the architecture and estimate the coefficients of the model. This machine learning methodology found that radial basis neural networks provided a very simple model in terms of the number of patient characteristics to be considered by the classifier (in this case, six), returning a good overall classification accuracy of 0.767 and a minimum sensitivity (for the classification of the minority class, untreated patients) of 0.550. Finally, the area under the ROC curve was 0.802, which proved to be exceptional. The parsimony of the model makes it especially attractive, using just eight connections. The independent variable "recent PWID" is compulsory due to its importance. The simplicity of the model means that it is possible to analyse the relationship between patient characteristics and the probability of belonging to the treated group.

Executive summary: Consensus document of GEHEP of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), along with SOCIDROGALCOHOL, SEPD and SOMAPA on hepatitis C virus infection management in drug users.

The micro-elimination of HCV infection in drug users (DU) in our area is a priority in order to achieve the overall elimination of this disease. Coordinated action between specialists in addiction treatment, microbiologists and physicians who treat HCV infection is required to implement infection screening, to achieve universal access to treatment and to prevent new infections and reinfections. The objective of this document was to come to a consensus on the screening, hospital referral, treatment, follow-up and prevention of HCV infection in DU by an expert panel from GEHEP/SEIMC and three scientific societies of addiction treating physicians: SEPD, SOCIDROGALCOHOL and SOMAPA.

HIV infection does not increase the risk of liver complications in hepatitis C virus-infected patient with advanced fibrosis, after sustained virological response with direct-acting antivirals.

OBJECTIVE: To assess the impact of HIV coinfection on the risk of developing liver-related complications in HCV-infected patients with advanced fibrosis treated with direct-acting antivirals (DAA) after sustained virological response (SVR). DESIGN: Prospective cohort study. SETTING: Multicenter. SUBJECTS: Patients from the GEHEP and HEPAVIR cohorts were selected if they fulfilled the following criteria: treatment against HCV with all oral DAA combination; SVR achievement, defined as undetectable plasma HCV RNA 12 weeks after the end of therapy; pretreatment liver stiffness equal to or higher than 9.5 kPa; liver stiffness measurement at the time of SVR. MAIN OUTCOME MEASURE(S): The primary variable was the time until the development of a liver complication or requiring liver transplant. RESULTS: Seven hundred and seventeen patients were included and 507 (71%) were coinfected with HIV. After a median follow-up time of 21 (14-25) months, 15 (2.1%) patients developed a liver complication and/or underwent a liver transplant and 15 (2.0%) died. The probability of remaining free of hepatic complications or transplant at 1 and 2 was, respectively, 99 and 96% in HCV-monoinfected patients and 99 and 98% in coinfected patients (P = 0.648). In a multivariate analysis, in which nonliver-related death was considered as a competing event, HIV coinfection was not associated with the appearance of hepatic complications or requiring liver transplant [hazard ratio = 0.24; 95% CI (0.03-1.93), P = 0.181]. Having presented hepatic decompensation prior to SVR [hazard ratio = 29.06; 95% CI (3.91-216.16), P < 0.001] and the value of liver stiffness at the SVR time-point (hazard ratio = 1.12; 95% CI (1.07-1.18), P < 0.001] were associated with a higher probability of development of liver events. CONCLUSION: HIV coinfection is not associated with a higher probability of developing liver complications in HCV-infected patients with advanced fibrosis, who achieved SVR with interferon-free regimens.

Low performance of ultrasound surveillance for the diagnosis of hepatocellular carcinoma in HIV-infected patients.

OBJECTIVE: To assess the performance of ultrasound surveillance for the diagnosis of hepatocellular carcinoma (HCC) in HIV-infected patients. METHODS: The GEHEP-002 cohort recruits HCC cases diagnosed in HIV-infected patients from 32 centers across Spain. The proportion of 'ultrasound lack of detection', defined as HCC diagnosed within the first 3 months after a normal surveillance ultrasound, and the proportion of 'surveillance failure', defined as cases in which surveillance failed to detect HCC at early stage, were assessed. To assess the impact of HIV, a control population of 104 HCC cases diagnosed in hepatitis C virus-monoinfected patients during the study period was used. RESULTS: A total of 186 (54%) out of 346 HCC cases in HIV-infected patients were diagnosed within an ultrasound surveillance program. Ultrasound lack of detection occurred in 16 (8.6%) of them. Ultrasound surveillance failure occurred in 107 (57%) out of 186 cases diagnosed by screening, whereas this occurred in 18 (29%) out of 62 diagnosed in the control group (P < 0.0001). HCC cases after ultrasound surveillance failure showed a lower frequency of undetectable HIV viral load at diagnosis. The probability of 1-year and 2-year survival after HCC diagnosis among those diagnosed by screening was 56 and 45% in HIV-infected patients, whereas it was 79 and 64% in HIV-negative patients (P = 0.038). CONCLUSION: The performance of ultrasound surveillance of HCC in HIV-infected patients is very poor and worse than that shown outside HIV infection. A HCC surveillance policy based on ultrasound examinations every 6 months might be insufficient in HIV-infected patients with cirrhosis.

Sustained virological response to direct-acting antiviral regimens reduces the risk of hepatocellular carcinoma in HIV/HCV-coinfected patients with cirrhosis.

Objectives: To assess the impact of all-oral direct-acting antiviral agent (DAA) regimens on the risk of hepatocellular carcinoma (HCC) in HIV/HCV-coinfected patients with cirrhosis. Methods: This was a multicentre prospective cohort study recruiting HIV/HCV-coinfected patients with a new diagnosis of compensated cirrhosis. Patients were followed up until HCC, death or the censoring date (March 2017). The primary endpoint was the emergence of HCC. The incidence rate (IR) (95% CI) of HCC in different groups was computed. Time-to-event analyses were performed to identify predictors of HCC emergence. Results: The study included 495 HIV/HCV-coinfected patients with cirrhosis. After a median (IQR) follow-up of 59 (27-84) months, 22 (4.4%; 95% CI 2.6-6.3) patients developed an HCC. The IR (95% CI) of HCC was 0.93 (0.06-1.42) per 100 person-years (PY). Three hundred and three (61%) patients achieved sustained virological response (SVR) during follow-up, 79 after interferon (IFN)-based regimens and 224 after an all-oral DAA regimen. The IR (95% CI) of HCC after all-oral DAA was 0.35 (0.14-0.85) per 100 PY whereas it was 1.79 (1.11-2.88) per 100 PY in the remaining cohort (P = 0.0005). When only patients with SVR were considered, the IR (95% CI) of HCC after all-oral DAA was 0.32 (0.12-0.86) whereas it was 0 per 100 PY among those with SVR after IFN-based therapies (P = 0.27). Achieving SVR with an all-oral DAA regimen during follow-up was independently associated with a lower risk of HCC emergence (subhazard ratio 0.264; 95% CI 0.070-0.991; P = 0.049). Conclusions: SVR with all-oral DAA regimens reduces the risk of HCC in HIV/HCV-coinfected patients with compensated cirrhosis.

Hepatocellular carcinoma after sustained virological response with interferon-free regimens in HIV/hepatitis C virus-coinfected patients.

OBJECTIVE: To assess the possible association between the use of direct antiviral agents (DAA) and the risk of hepatocellular carcinoma (HCC) in HIV/hepatitis C virus (HCV)-coinfected patients. METHODS: The GEHEP-002 cohort recruits HCC cases in HIV-infected patients from 32 centers from Spain. Three analyses were performed: the proportion of HCC cases after sustained virological response (SVR) and the evolution of this proportion over time, the frequency of HCC after SVR in HIV/HCV-coinfected patients with cirrhosis, and the probability of HCC recurrence after curative therapies among those undergoing HCV therapy. RESULTS: Forty-two (13%) out of 322 HCC cases in HIV/HCV-coinfected patients occurred after SVR. Twenty-eight (10%) out of 279 HCC cases diagnosed during the years of use of IFN-based regimens occurred after SVR whereas this occurred in 14 (32.6%) out of the 43 HCC cases diagnosed in the all-oral DAA period (P < 0.0001). One thousand, three hundred and thirty-seven HIV/HCV-coinfected patients with cirrhosis achieved SVR in the cohort. The frequency of HCC after SVR declined from 15% among those cured with pegylated-IFN with ribavirin to 1.62 and 0.87% among those cured with DAA with and without IFN, respectively. In patients with previous HCC treated with curative therapies, HCC recurrence occurred in two (25%) out of eight patients treated with IFN-based regimens and four (21%) out of 19 treated with DAA-IFN-free regimens (P = 1.0). CONCLUSION: The frequency of HCC emergence after SVR has not increased after widespread use of DAA in HIV/HCV-coinfected patients. DAA do not seem to impact on HCC recurrence in the short-term among those with previously treated HCC.

Changes in Liver Steatosis After Switching From Efavirenz to Raltegravir Among Human Immunodeficiency Virus-Infected Patients With Nonalcoholic Fatty Liver Disease.

BACKGROUND: Antiretroviral drugs with a lower potential to induce hepatic steatosis in human immunodeficiency virus (HIV) infection need to be identified. We compared the effect of switching efavirenz (EFV) to raltegravir (RAL) on hepatic steatosis among HIV-infected patients with nonalcoholic fatty liver disease (NAFLD) receiving EFV plus 2 nucleoside analogues. METHODS: HIV-infected patients on EFV plus tenofovir/emtricitabine or abacavir/lamivudine with NAFLD were randomized 1:1 to switch from EFV to RAL (400 mg twice daily), maintaining nucleoside analogues unchanged, or to continue with EFV plus 2 nucleoside analogues. At baseline, eligible patients should show controlled attenuation parameter (CAP) values ≥238 dB/m. Changes in hepatic steatosis at 48 weeks of follow-up over baseline levels were measured by CAP. RESULTS: Overall, 39 patients were included, and 19 of them were randomized to switch to RAL. At week 48, median CAP for the RAL group was 250 (Q1-Q3, 221-277) dB/m and 286 (Q1-Q3, 269-314) dB/m for the EFV group (P = .035). The median decrease in CAP values was -20 (Q1-Q3, -67 to 15) dB/m for the RAL arm and 30 (Q1-Q3, -17 to 49) dB/m for the EFV group (P = .011). CAP values <238 dB/m at week 48 were observed in 9 (47%) patients on RAL and 3 (15%) individuals on EFV (P = .029). CONCLUSIONS: After 48 weeks, HIV-infected individuals switching EFV to RAL showed decreases in the degree of hepatic steatosis, as measured by CAP, compared with those continuing with EFV. In addition, the proportion of patients without significant hepatic steatosis after 48 weeks was greater for those who switched to RAL. CLINICAL TRIALS REGISTRATION: NCT01900015.

Real-life experience with sorafenib for the treatment of hepatocellular carcinoma in HIV-infected patients.

OBJECTIVE: To report the real-life results of sorafenib use in a cohort of HIV-infected patients with hepatocellular carcinoma (HCC). METHODS: The GEHEP-002 cohort (ClinicalTrials.gov ID: NCT02785835) has recruited 302 HCC cases diagnosed in HIV-infected patients from 32 centers from Spain. RIS-HEP12 study included 44 (14%) cases that have received at least one dose of sorafenib. The overall survival after the start of treatment was the main efficacy outcome. Permanent discontinuation due to adverse events was the primary safety end point. RESULTS: Reasons for sorafenib use are HCC recurrence after previous curative therapy (n = 7), progression following transarterial chemoembolization (n = 6) and first treatment against HCC (n = 31). Nineteen (43%) patients harbored Child-Pugh B cirrhosis. Barcelona-Clinic Liver Cancer stage was A 3 (7%), B 6 (14%), C 30 (68%) and D 5 (11%). All patients were on antiretroviral therapy (ART). The median (Q1-Q3) duration of sorafenib treatment was 70 (31-158) days. Median survival was 7.2 months, whereas the median (Q1-Q3) duration of overall survival after the start of treatment was 4 (2-9.7) months. Twenty-six (59%) patients had any grade adverse events and 19 (43%) suffered a decompensation. Discontinuation due to adverse events occurred in 17 (38.6%) patients. There were no modifications or discontinuations of ART. CD4 cell counts and HIV viral load remained stable. CONCLUSION: The efficacy of sorafenib under real-life conditions in HIV-infected patients seems lower than that reported in the registration clinical trial. On the contrary, the tolerability of sorafenib appears to be similar to what is seen in patients without HIV infection. Sorafenib does not seem to modify the efficacy of ART.

Progression of liver stiffness predicts clinical events in HIV/HCV-coinfected patients with compensated cirrhosis.

BACKGROUND: Our objective was to assess the predictive value of the changes of liver stiffness (LS) for clinical outcome in HIV/HCV-coinfected patients with compensated liver cirrhosis and a LS value < 40 kPa. METHODS: Prospective cohort of 275 HIV/HCV-coinfected patients with cirrhosis, no previous liver decompensation (LD) and LS < 40 kPa. The time from diagnosis to LD and/or hepatocellular carcinoma (HCC) and the predictors of this outcome were evaluated. Significant progression of LS was defined as an increase ≥ 30 % over the baseline value at any time during the follow-up. RESULTS: After a median (Q1-Q3) follow-up of 32 (20-48) months, 19 (6.9 %, 95 % CI: 3.8 %-9.9 %) patients developed a first LD and/or HCC. At the end of the follow-up, 247 (90 %) patients had undergone a further LS examination. Of them, 77 (31 %) patients had a significant progression of LS. The mean (SD) survival time free of LD and/or HCC was 67 (3) and 77 (1) months in patients with or without significant progression of LS (p = 0.01). Significant progression of LS was an independent predictor of LD and/or HCC (Adjusted Hazard Ratio 4.63; 95 % confidence interval: 1.34-16.02; p = 0.015). CONCLUSIONS: Significant progression of LS is associated with a higher risk of clinical events in HIV/HCV-coinfected patients with compensated cirrhosis and LS < 40 kPa.

Low risk of liver decompensation among human immunodeficiency virus/hepatitis C virus-coinfected patients with mild fibrosis in the short term.

UNLABELLED: Liver fibrosis is used to make decisions about the timing of therapy against hepatitis C virus (HCV) in routine clinical practice, which should be based on the short-term likelihood of liver decompensations. Thus, we aimed at evaluating the risk of decompensations and death among human immunodeficiency virus (HIV)/HCV-coinfected individuals according to their baseline fibrosis classified by either liver biopsy or liver stiffness measurement (LSM). Patients coinfected with HIV/HCV, naive or without sustained virological response to HCV therapy, were included in this cohort. Fibrosis was classified by biopsy in 683 patients and by LSM in 1046 individuals. Reference categories were fibrosis stage 0 and LSM <6 kPa. For patients with biopsy, the adjusted subhazard ratio for decompensations and 95% confidence interval (95% CI) by fibrosis stage were as follows: stage 1, 2.3 (0.27-20.3), P = 0.443; stage 2, 2.8 (0.33-24), P = 0.345; stage 3, 4.91 (0.60-41), P = 0.137; stage 4, 9.89 (1.25-79.5), P = 0.030. For patients with LSM, the adjusted subhazard ratio and 95% CI by LSM category were as follows: 6-9.4 kPa, 1.89 (0.18-20.3), P = 0.599; 9.5-14.5 kPa, 6.59 (0.73-59.2), P = 0.092; ≥14.6 kPa, 59.5 (8.3-427), P < 0.0001. Regarding the risk of death, the adjusted hazard ratio and 95% CI for death by fibrosis stage were as follows: stage 1, 1.3 (0.4-4.11), P = 0.677; stage 2, 2.68 (0.86-8.36), P = 0.090; stage 3, 2.58 (0.82-8.15), P = 0.106; stage 4, 4.35 (1.43-13.3), P = 0.010. For patients with LSM, the adjusted hazard ratio and 95% CI for death by LSM were as follows: 6-9.4 kPa, 1.7 (0.63-4.79), P = 0.288; 9.5-14.5 kPa, 3.38 (1.2-9.5), P = 0.021; ≥14.6 kPa, 12.7 (4.9-33.6), P < 0.0001. CONCLUSION: Patients coinfected with HIV/HCV without advanced fibrosis are at very low risk of decompensations in the short term; deferral of HCV therapy for a few years and monitoring fibrosis progression is a safe option until cheaper, more effective, and more convenient HCV treatment becomes widely available.

Risk of liver decompensation among HIV/hepatitis C virus-coinfected individuals with advanced fibrosis: implications for the timing of therapy.

BACKGROUND: Most human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-infected patients who are currently receiving boceprevir or telaprevir-based therapy against HCV show cirrhosis. However, the risk of liver decompensation (DC) among HIV/HCV-coinfected patients with stage 3 fibrosis in the short term could be high enough to not allow delays. We aimed at assessing the risk of DC among HIV/HCV-coinfected individuals with advanced fibrosis (F3-F4). METHODS: Eight hundred ninety-two HIV/HCV-coinfected patients, naive or without sustained virologic response to HCV therapy, were included in this cohort. Fibrosis was staged by biopsy in 317 patients and by liver stiffness measurement (LSM) in 575 individuals. Precirrhosis was defined as an LSM of 9.5-14.6 kilopascals (kPa), and cirrhosis as an LSM of ≥14.6 kPa. RESULTS: For patients with biopsy, the probability of remaining free of DC for F3 vs F4 was 99% (95% confidence interval [CI], 95%-100%) vs 96% (95% CI, 91%-98%) at 1 year, and 98% (95% CI, 94%-100%) vs 87% (95% CI, 81%-92%) at 3 years. The only factor independently associated with DC was fibrosis stage (F4 vs F3, subhazard ratio [SHR], 2.1; 95% CI, 1.07-4.1; P = .032). For patients with LSM, the probability of remaining free of DC for precirrhosis vs cirrhosis was 99% (95% CI, 96%-100%) vs 93% (95% CI, 89%-96%) at 1 year, and 97% (95% CI, 94%-99%) vs 83% (95% CI, 77%-87%) at 3 years. Factors independently associated with DC were platelet count (<100 × 10(3) vs ≥100 × 10(3): SHR, 1.86; 95% CI, 1.01-3.42; P = .046) and LSM (cirrhosis vs precirrhosis: SHR, 5.67; 95% CI, 2.27-14.1; P < .0001). CONCLUSIONS: As in patients with cirrhosis, immediate therapy against HCV is warranted for patients with precirrhosis and HIV coinfection, as they are at risk of DC soon after the diagnosis of advanced fibrosis.

Condrosarcoma gigante de la pared torácica: presentación de un caso / Giant chondrosarcoma of the thoracic wall: a case presentation

Introducción: el condrosarcoma es un tumor maligno de células productoras de cartílago y se divide en dos tipos: primario y secundario, aunque se puede clasificar también atendiendo a la localización y el grado histológico. Objetivo: presentar un caso infrecuente de condrosarcoma gigante de la pared torácica con infiltración de la parrilla costal izquierda. Caso clínico: se presenta un paciente de 74 años con antecedentes de hipertensión arterial y acude al Servicio de Cirugía por presentar desde hacía 13 años aumento de volumen en la región pectoral izquierda, que desde hace seis meses aceleró su crecimiento. Se destacó al examen físico tumoración de 15 cm en la región precordial izquierda, adherida a planos profundos, no desplazable, no dolorosa a la palpación, multilobulada, caliente, con circulación venosa superficial visible. Conclusiones: el diagnóstico histológico se correspondió con condrosarcoma primario. La conducta a seguir en este paciente fue la cirugía con resección en bloque de la masa tumorosa y toracoplastia, pero después presentó complicaciones en la Unidad de Terapia Intensiva y falleció por un tromboembolismo pulmonar en silla de montar.

Background: chondrosarcoma is a malignant tumor of the cartilage-producing cells and it is divided into two groups: primary and secondary, but it can be also classified according to the location and the histological degree. Objective: to present an infrequent case of giant chondrosarcoma of the thoracic wall with infiltration in the left ribs. Clinical case: a seventy-four-year-old patient with hypertension antecedents came to the Surgery Department because, for 13 years, he showed volume increase in his left pectoral region; the growth had accelerated in the last six months. In the physical examination a fifteen-centimeter tumor was detected in the left precordial region, adhered to deep planes; it was non-displaced, non-painful, multilobate, hot, and with visible superficial venous circulation. Conclusions: the histological diagnosis was primary chondrosarcoma. The patient underwent a surgery with block removal of the tumorous mass and thoracoplasty; but soon afterward he showed complications while staying in the Intensive Care Unit and died of pulmonary thromboembolism in sella.

Reappraisal of the outcome of healthcare-associated and community-acquired bacteramia: a prospective cohort study.

BACKGROUND: Healthcare-associated (HCA) bloodstream infections (BSI) have been associated with worse outcomes, in terms of higher frequencies of antibiotic-resistant microorganisms and inappropriate therapy than strict community-acquired (CA) BSI. Recent changes in the epidemiology of community (CO)-BSI and treatment protocols may have modified this association. The objective of this study was to analyse the etiology, therapy and outcomes for CA and HCA BSI in our area. METHODS: A prospective multicentre cohort including all CO-BSI episodes in adult patients was performed over a 3-month period in 2006-2007. Outcome variables were mortality and inappropriate empirical therapy. Adjusted analyses were performed by logistic regression. RESULTS: 341 episodes of CO-BSI were included in the study. Acquisition was HCA in 56% (192 episodes) of them. Inappropriate empirical therapy was administered in 16.7% (57 episodes). All-cause mortality was 16.4% (56 patients) at day 14 and 20% (71 patients) at day 30. After controlling for age, Charlson index, source, etiology, presentation with severe sepsis or shock and inappropriate empirical treatment, acquisition type was not associated with an increase in 14-day or 30-day mortality. Only an stratified analysis of 14th-day mortality for Gram negatives BSI showed a statically significant difference (7% in CA vs 17% in HCA, p = 0,05). Factors independently related to inadequate empirical treatment in the community were: catheter source, cancer, and previous antimicrobial use; no association with HCA acquisition was found. CONCLUSION: HCA acquisition in our cohort was not a predictor for either inappropriate empirical treatment or increased mortality. These results might reflect recent changes in therapeutic protocols and epidemiological changes in community pathogens. Further studies should focus on recognising CA BSI due to resistant organisms facilitating an early and adequate treatment in patients with CA resistant BSI.

Liver stiffness measurement versus liver biopsy to predict survival and decompensations of cirrhosis among HIV/hepatitis C virus-coinfected patients.

OBJECTIVE: To compare the prognostic performance of liver biopsy with that of liver stiffness measurement (LSM) to predict survival and liver decompensations among HIV/hepatitis C virus (HCV)-coinfected patients. DESIGN: Retrospective cohort study. METHODS: Cohort of 297 HIV/HCV-coinfected patients, who underwent a liver biopsy and LSM separated by 12 months or less, followed in 10 Spanish tertiary care centers from December 2005 to December 2011 (median follow-up, 5 years; interquartile range, 4.2-5.4 years). Liver biopsies were staged following the Scheuer's score. LSM was obtained by hepatic transient elastometry. A survival analysis was carried out and the integrated discrimination improvement was computed to compare the ability of the survival models to predict outcomes. The incidence of death from any cause and of development of the first decompensation of cirrhosis was calculated. RESULTS: Overall mortality rate was 1.63 [95% confidence interval (CI) 1.06-2.49] per 100 person-years. The adjusted hazard ratio [AHR (95% CI)] of baseline fibrosis (per stage of fibrosis) was 1.52 (1.08-2.15, P=0.017) and of LSM (per 5 kPa increase) 1.28 (1.12-1.46, P<0.001). LSM including models yielded a performance 3.9% better than the liver biopsy-based models (P=0.072). For the prediction of liver decompensations, the AHR (95% CI) of baseline fibrosis by liver biopsy (per stage of fibrosis) was 1.67 (1.15-2.43, P=0.007) and of LSM (per 5 kPa increase) 1.37 (1.21-1.54, P<0.001). LSM-based models yielded a performance 8.4% better than the liver biopsy-based models (P=0.045). CONCLUSION: LSM-based prediction achieves a similar yield than liver biopsy-based models to predict overall mortality in HIV/HCV-coinfected patients. Models including LSM could predict better liver decompensations than liver biopsy.
