Por su parte, en los auxiliares de enfermería el comportamiento en algunas subescalas fue muy similar; el 14,5% obtuvo una puntuación alta para cansancio emocional; 12,8%, para despersonalización y 59,8% obtuvo puntuaciones bajas para la realización personal. Conclusiones La presencia del síndrome de burnout en la población estudiada es alta. Es similar tanto en enfermeros como en auxiliares de enfermería. La dimensión más afectada fue la realización personal en ambos grupos estudiados, lo cual corresponde a sentimientos altos del "quemado".

ABSTRACT Objective To determine the prevalence of burnout syndrome in the nursing staff in four hospitals located in the State of Atlántico (Colombia). Material and Methods A descriptive cross-sectional study was conducted and included as participants 117 nursing professionals and 229 nursing auxiliaries from four hospitals located in the State of Atlantico (Colombia), two public and two privates. An anonymous self-study survey was used on sociodemographic, labor data and Maslach Scale. Results The overall prevalence of Burnout Syndrome or professional burnout was 65%. In nursing professionals it was 63,2% and in nursing auxiliaries 65,9%. At least 13,3% of the participants had a high degree of Burnout from emotional exhaustion, 9.2% for depersonalization, and 62,7% had low scores for personal fulfillment. In nursing professionals, 12,7% had a high score for emotional exhaustion, 7,4% for depersonalization, and 64,2% obtained low scores for personal fulfillment. On the other hand, in nursing auxiliaries the behavior in some subscales was very similar, 14,5% had a high score for emotional exhaustion, 12,8% for depersonalization and 59,8% had low scores for personal fulfillment. Conclusions The presence of burnout syndrome is high in the studied population, it is similar in both, nurses and nursing auxiliaries. The most affected dimension was the personal fulfillment in both groups, which corresponds to high feelings of the "burned".

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.

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.

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.

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.

Adverse drug reactions in hospitalized Colombian children / Reacciones adversas a medicamentos en niños hospitalizados en Colombia

Abstract Introduction: The occurrence of adverse drug reactions is an important issue due to the lack of drug safety data in children. Objective: To describe the Adverse Drug Reactions in inpatient children under 6 years of age in two general pediatrics wards located in Barranquilla, Colombia. Methods: A prospective cohort study based on intensive pharmacovigilance was conducted during six months in order to monitor the emergence of Adverse Drug Reactions in inpatients children under 6 years of age with at least one medication prescribed. The study was conducted in two pediatric wards of two hospitals located in Barranquilla, Colombia. Naranjo´s Algorithm was used to evaluate imputability, the modified Hartwig and Siegel assessment scale to establish severity and the Schumock and Thornton criteria to determine preventability. Results: Of a total of 772 monitored patients, 156 Adverse Drug Reactions were detected on 147 children. The cumulative incidence of Adverse Drug Reactions was 19.0% (147/772); the incidence density was 37.6 Adverse Drug Reactions per 1,000 patients-days (147/3,913). The frequency was higher in children under 2 years of age (12.7%). Emergence of Adverse Drug Reactions was higher in male patients (RR= 1.66; 95% CI= 1.22-2.22, p= 0.001) and in those who used systemic antibiotics (RR= 1.82; 95% CI= 1.17-2.82, p= 0.005). Conclusions: Adverse Drug Reactions are common among hospitalized children and represent an additional burden of morbidity and risk, particularly in those who used several medicines, including antibiotics...(AU)

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.

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.

Response to pegylated interferon plus ribavirin among HIV/hepatitis C virus-coinfected patients with compensated liver cirrhosis.

BACKGROUND: The objective of this study was to determine the efficacy of pegylated interferon (peg-IFN) plus ribavirin (RBV) in human immunodeficiency virus (HIV)-infected patients with hepatitis C virus (HCV)-related compensated liver cirrhosis, as well as the predictors of response in these individuals. METHODS: All subjects enrolled in a prospective cohort of 841 HIV/HCV-coinfected patients who received peg-IFN and RBV and who had a liver biopsy or a liver stiffness measurement within the year before starting peg-IFN plus RBV were included in this study. The sustained virologic response (SVR) rate and predictors of SVR response were analyzed. RESULTS: A total of 629 patients were included in this study; 175 (28%) had cirrhosis. In an intention-to-treat analysis, 44 (25%) patients with cirrhosis and 177 (39%) without cirrhosis achieved SVR (P = .001). Among patients with cirrhosis, SVR was observed in 14%, 47%, and 30% of individuals with HCV genotypes 1, 2-3, and 4, respectively. Discontinuation of therapy owing to adverse events was observed in 30 (17%) individuals with cirrhosis and 37 (8%) subjects without cirrhosis (P = .001). CONCLUSIONS: The efficacy of peg-IFN plus RBV among HIV/HCV-coinfected patients with cirrhosis is lower than in those without cirrhosis, although this antiviral combination still leads to a substantial rate of SVR in those carrying HCV genotype 3. A higher rate of discontinuations of HCV therapy due to adverse events among cirrhotic patients could partially explain the differences in the SVR rate between both populations.

Liver stiffness predicts clinical outcome in human immunodeficiency virus/hepatitis C virus-coinfected patients with compensated liver cirrhosis.

UNLABELLED: Our aim was to assess the predictive value of liver stiffness (LS), measured by transient elastography (TE), for clinical outcome in human immunodeficiency virus / hepatitis C virus (HIV/HCV)-coinfected patients with compensated liver cirrhosis. This was a prospective cohort study of 239 consecutive HIV/HCV-coinfected patients with a new diagnosis of cirrhosis, done by TE, and no previous decompensation of liver disease. The time from diagnosis to the first liver decompensation and death from liver disease, as well as the predictors of these outcomes, were evaluated. After a median (Q1-Q3) follow-up of 20 (9-34) months, 31 (13%, 95% confidence interval [CI]: 9%-17%) patients developed a decompensation. The incidence of decompensation was 6.7 cases per 100 person-years (95% CI, 4.7-9-6). Fourteen (8%) out of 181 patients with a baseline LS < 40 kPa developed a decompensation versus 17 (29%) out of 58 with LS ≥ 40 kPa (P = 0.001). Factors independently associated with decompensation were Child-Turcotte-Pugh (CTP) class B versus A (hazard ratio [HR] 7.7; 95% CI 3.3-18.5; P < 0.0001), log-plasma HCV RNA load (HR 2.1; 95% CI 1.2-3.6; P = 0.01), hepatitis B virus coinfection (HR, 10.3; 95% CI, 2.1-50.4; P = 0.004) and baseline LS (HR 1.03; 95% CI 1.01-1.05; P = 0.02). Fifteen (6%, 95% CI: 3.5%-9.9%) patients died, 10 of them due to liver disease, and one underwent liver transplantation. CTP class B (HR 16.5; 95% CI 3.4-68.2; P < 0.0001) and previous exposure to HCV therapy (HR 7.4; 95% CI 1.7-32.4, P = 0.007) were independently associated with liver-related death; baseline LS (HR 1.03; 95% CI 0.98-1.07; P = 0.08) was of borderline significance. CONCLUSION: LS predicts the development of hepatic decompensations and liver-related mortality in HIV/HCV-coinfection with compensated cirrhosis and provides additional prognostic information to that provided by the CTP score.

Natural history of compensated hepatitis C virus-related cirrhosis in HIV-infected patients.

OBJECTIVE: To provide information about the incidence and predictors of liver decompensation and death due to liver failure in human immunodeficiency virus (HIV)-infected patients with compensated hepatitis C virus (HCV)-related cirrhosis. METHODS: Prospective cohort study of 154 HIV-HCV-coinfected patients with a new diagnosis of Child-Pugh-Turcotte (CPT) class A compensated cirrhosis. We evaluated time from diagnosis to the first liver decompensation and death from liver disease, as well as predictors of these outcomes. RESULTS: Thirty-six patients (23.4%) developed liver decompensation. The incidence of liver decompensation was 6.40 cases per 100 person-years (95% confidence interval [CI], 4.18-9.38 cases per 100 person-years). Factors independently associated with liver decompensation were lack of HCV therapy (hazard ratio [HR], 3.38; 95% CI, 1.09-10.53; P = .035), baseline CD4 cell counts

Application of transient elastometry to differentiate mild from moderate to severe liver fibrosis in HIV/HCV co-infected patients.

BACKGROUND/AIMS: Transient elastometry (TE) is accurate for detecting cirrhosis (F=4) in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infected patients. However, this procedure is less precise to differentiate mild (F < or = 1) from moderate to severe (F > or = 2) fibrosis using the cut-off value of 7.2kPa, a level previously proposed by some authors. Because of this, we elaborated and validated cut-off values of liver stiffness (LS) to better discriminate F < or = 1 from F > or = 2 in HIV/HCV co-infected subjects to aid therapy decisions. METHODS: One hundred and ninety-seven co-infected patients with liver biopsy and TE measurement, without prior therapy against HCV infection, were included. RESULTS: To diagnose F < or = 2, a cut-off of 9.0kPa showed a positive predictive value of 87%. To discard F > or = 2, a cut-off of 6.0kPa showed a negative predictive value of 90%. Considering all the patients, 61 (31%) patients yielded LS values < or = 6.0kPa and 81 (41%) patients showed LS values > or = 9.0kPa. There were no severe classification errors as the NPV of L < or = S6.0kPa for F > or = 3 was 100% and the NPV LS > or = 9.0kPa for F=0 was also 100%. CONCLUSIONS: The usefulness of TE can be enhanced using two different cut-off values to identify patients with F < or = 1 and F > or = 2.

Influence of concomitant antiretroviral therapy on the rate of sustained virological response to pegylated interferon plus ribavirin in hepatitis C virus/HIV-coinfected patients.

OBJECTIVES: To investigate whether concomitant antiretroviral therapy (ART) is a predictor of sustained virological response (SVR) in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients treated with pegylated interferon plus ribavirin. METHODS: Three hundred and ten HIV/HCV-coinfected patients on pegylated interferon plus ribavirin treatment, 258 of them with concurrent ART, were included in this retrospective multicentre study. The predictors of SVR were evaluated. RESULTS: SVR was shown by 114 (37%) subjects. HCV genotype 2 or 3, plasma HCV-RNA load lower than 600 000 IU/mL, an exposure to the therapy against HCV infection > or =80% of the planned dose and baseline CD4 cell counts higher than or equal to 300/mm(3) were predictors of SVR. Likewise, patients without ART and those receiving a combination including tenofovir or stavudine plus lamivudine plus a protease inhibitor (PI) or a non-nucleoside reverse transcriptase inhibitor (NNRTI) showed a higher SVR rate than the subjects who were on other ART strategies at baseline [44%, 44% and 29%, respectively; adjusted odd ratio (95% CI) for no ART = 1.96 (1.07-4.76), P = 0.025, and for ART including tenofovir or stavudine plus lamivudine plus a PI or a NNRTI = 2.08 (1.16-3.70), P = 0.014]. CONCLUSIONS: The ART strategy on starting therapy with pegylated interferon plus ribavirin is a predictor of SVR in HIV/HCV-coinfected patients. Subjects without ART and those receiving combinations of a PI or a NNRTI with a nucleos(t)ide backbone of tenofovir or stavudine plus lamivudine respond better than those who receive other regimens.

The use of transient elastometry for assessing liver fibrosis in patients with HIV and hepatitis C virus coinfection.

BACKGROUND: Transient elastometry (TE) is accurate for detecting significant liver fibrosis and cirrhosis in hepatitis C virus (HCV)-monoinfected patients. However, this procedure has been insufficiently validated in patients with human immunodeficiency virus (HIV) and HCV coinfection. The purpose of this study was to validate reported cutoff values of TE that discriminate significant liver fibrosis and cirrhosis in HIV-HCV-coinfected subjects. METHODS: Liver stiffness measurements were obtained for 169 HIV-HCV-coinfected adult patients who had undergone a liver biopsy or who had received a nonhistologic diagnosis of cirrhosis within 12 months before or after a liver stiffness measurement. Patients had received no prior therapy for HCV infection. RESULTS: TE measurements ranged from 3.6 kPa to 75 kPa. The area under the receiver operating characteristic curve was 0.87 (95% confidence interval, 0.84-0.93) for significant liver fibrosis and 0.95 (95% confidence interval, 0.92-0.99) for cirrhosis. To diagnose significant liver fibrosis, a cutoff value of 7.2 kPa was associated with a positive predictive value of 88% and a negative predictive value of 75%. Thirty-four patients (20%) were misclassified when this cutoff value was used. Thirteen (24%) of 54 patients with liver stiffness values <7.2 kPa had significant liver fibrosis detected by liver biopsy. To diagnose cirrhosis, a cutoff value of 14.6 kPa was associated with a positive predictive value of 86% and a negative predictive value of 94%. Thus, 13 patients (10%) had disease that was misclassified using this cutoff value. CONCLUSIONS: We found that the diagnostic accuracy of TE was high for detecting cirrhosis and good for diagnosis of significant liver fibrosis. However, the performance of TE was low for discriminating mild fibrosis from significant liver fibrosis, which might limit the applicability of this technique in clinical practice.

Predictors of severe haematological toxicity secondary to pegylated interferon plus ribavirin treatment in HIV-HCV-coinfected patients.

BACKGROUND: Haematological adverse events related to pegylated interferon (PEG-IFN) and ribavirin (RBV) therapy could affect the patients' quality of life; however, the risk factors for severe haematological toxicity associated with this therapy in patients coinfected with hepatitis C virus (HCV) and HIV are unclear. The objective of this study was to identify predictors of severe haematological toxicity among HIV-HCV-coinfected patients treated with PEG-IFN plus RBV. METHODS: This retrospective multicentric study included 237 HIV-HCV-coinfected patients on PEG-IFN plus RBV. Predictors of severe anaemia, neutropenia, thrombocytopenia and overall haematological toxicity were analyzed. RESULTS: Eighty (34%) individuals showed an episode of severe haematological toxicity. Severe anaemia, neutropenia and thrombocytopenia occurred in 32 (13%), 42 (18%) and 26 (11%) patients, respectively. In the multivariate analysis, zidovudine use (adjusted odds ratio [AOR] 3.3; 95% confidence interval [CI] 1.6-10; P = 0.001), baseline body weight < 65 kg (AOR 2.5; 95% CI 1.1-5; P = 0.024), cirrhosis (AOR 5; 95% CI 1.6-16.6; P = 0.006), PEG-IFN-alpha2a (AOR 2.7; 95% CI 1.1-6.6; P = 0.029) and pretreatment haemoglobin level < 14 g/dl (AOR 2.7; 95% CI 1.3-5.5; P = 0.005) were associated with any kind of severe haematological toxicity. Likewise, haemoglobin level < 13 g/dl, neutrophil counts < 2,500 cells/mm3 and platelet counts < 175,000 cells/mm3 were independent predictors of severe anaemia, neutropenia and thrombocytopenia, respectively. CONCLUSIONS: Zidovudine treatment, cirrhosis, baseline low body weight, use of PEG-IFN-alpha2a, and baseline haemoglobin level < 14 g/dl are predictors of overall severe haematological toxicity secondary to PEG-IFN plus RBV in HIV-infected individuals. Low pretreatment levels of each haematological series predict a significant decrease of their values during therapy.

Incidence of and risk factors for severe hepatotoxicity of nelfinavir-containing regimens among HIV-infected patients with chronic hepatitis C.

OBJECTIVES: To determine the incidence of and risk factors for severe hepatotoxicity of nelfinavir-containing regimens among human immunodeficiency virus/hepatitis C virus (HIV/HCV)-coinfected patients with known stage of liver fibrosis. METHODS: All HIV/HCV-coinfected patients were monitored for a period of 12 months after starting nelfinavir-containing regimens and, with an available liver biopsy, were included in a retrospective study. RESULTS: A total of 82 patients were included in the study. Nine (10.9%) HIV/HCV-coinfected patients showed an episode of severe hepatotoxicity during the study period. Eight (9.8%) individuals showed grade 3 or 4 change in levels of serum alanine aminotransferase and one subject presented with an event of decompensated liver cirrhosis. Six (18.2%) of 33 patients with advanced liver fibrosis and three (6%) of 49 individuals without advanced liver fibrosis showed an episode of severe hepatotoxicity (P = 0.1). In the multivariate analysis, only nevirapine use during nelfinavir therapy [adjusted odds ratio (AOR) 8.9; 95% confidence interval (CI), 1.4-54.1; P = 0.01] was independently associated with risk of development of severe liver toxicity. CONCLUSIONS: The incidence of severe hepatotoxicity of nelfinavir-containing regimens is low among HIV/HCV-coinfected patients with known stage of liver fibrosis. In addition, our findings show that concomitant nevirapine use is associated with an increased risk of severe hepatotoxicity in these subjects. Likewise, the proportion of severe liver toxicity tended to be higher in individuals with advanced liver fibrosis.
