ABSTRACT
Contradictory data about the impact of the rs738409 steatosis-related polymorphism within PNPLA3 gene on liver fibrosis progression in HIV/hepatitis C virus (HIV/HCV)-coinfected patients have been reported. Our objective was to test whether this, and other polymorphisms previously related to fatty liver disease in HIV infection linked to SAMM50 or LPPR4 genes, influence liver fibrosis progression in HIV/HCV-coinfected individuals. Three hundred and thirty two HIV/HCV-coinfected patients who consecutively attended four Spanish university hospitals from November 2011 to July 2013 were included. A liver stiffness cut-off of 14.6 kPa, as determined by transient elastography, was used to diagnose cirrhosis. Liver stiffness progression was studied in 171 individuals who had two available LS determinations without anti-HCV treatment between them. Moreover, 28 HIV/HCV-coinfected patients who underwent liver transplant, as well as 19 non-cirrhotic coinfected individuals used as controls, were included in an additional study. Only rs738409 was associated with cirrhosis: 45 (29.6%) of 152 G allele carriers versus 36 (20.0%) of 180 CC carriers showed cirrhosis (multivariate p = 0.018; adjusted odds ratio = 1.98; 95% confidence interval = 1.12-3.50). Also, 21 (30.4%) of 69 G allele carriers versus 16 (15.7%) of 102 CC patients showed significant liver stiffness progression (adjusted p-value = 0.015; adjusted odds ratio = 2.89; 95% confidence interval = 1.23-6.83). Finally, the proportion of rs738409 G allele carriers was significantly higher in transplanted individuals than in controls (p = 0.044, odds ratio = 3.43; 95% confidence interval = 1.01-11.70). Our results strongly suggest that the rs738409 polymorphism is associated with liver fibrosis progression in HIV/HCV-coinfected patients.

INTRODUCTION: Pegylated interferon plus ribavirin (Peg-IFN/RBV) therapy leads to improvements in liver stiffness measurements (LSM) in hepatitis C virus (HCV)-infected patients. However, the rate of LSM return to normal values in response to Peg-IFN/RBV is unclear. Thus, our aim was to assess the probability and factors associated with LSM normalization in HCV-infected patients receiving Peg-IFN/RBV. METHODS: This prospective observational longitudinal study included 160 HCV-infected patients, 111 (69%) with human immunodeficiency virus and receiving Peg-IFN/RBV, with baseline LSM ≥ 7kPa. The outcome variable was LSM normalization, i.e. a stable decrease in LSM below 7kPa after starting Peg-IFN/RBV. RESULTS: After starting Peg-IFN/RBV, 56 [35%, 95% confidence interval (95% CI): 28-42%] patients showed LSM normalization. The probability of LSM normalization was 21% (95% CI: 13.2-32.4%) at 12 months, and 51.3% (95% CI: 39.9-63.9%) at 24 months after Peg-INF/RBV initiation for individuals with sustained virological response (SVR), and 8.3% (95% CI: 4-16.6%) at 12 months and 11.3% (95% CI: 6-20.7%) at 24 months for those without SVR (p < 0.001). For individuals with LSM ≥7kPa 24 weeks after the pre-planned end of treatment, LSM normalizations were only observed among those with SVR. Achievement of SVR [Hazard ratio (HR, 95% CI): 6.84 (3.39-13.81)] and lack of baseline cirrhosis [HR (95% CI): 4.17 (1.69-10)] were independently associated with LSM normalization after starting Peg-IFN/RBV. CONCLUSIONS: LSM normalizations during Peg-IFN/RBV treatment are more likely, and occur earlier among patients with SVR. In addition, LSM normalizations continue 24 weeks after the scheduled end of therapy, but only among individuals who reach SVR
INTRODUCCIÓN: El retorno de la rigidez hepática (RH) a valores normales en respuesta al tratamiento de la infección por hepatitis C (VHC) con Peg-IFN/RBV no está claro. Por ello, evaluamos la probabilidad y los factores asociados con la normalización de la RH en pacientes tratados con Peg-IFN/RBV. MÉTODOS: Se incluyeron 160 pacientes infectados por VHC en este estudio longitudinal prospectivo, 111 (69%) de ellos por el virus de la inmunodeficiencia humana, con RH basal ≥ 7kPa y que recibieron Peg-IFN/RBV. La variable principal fue la disminución estable de la RH < 7kPa. RESULTADOS: Después de iniciar Peg-IFN/RBV, 56 (35%; intervalo de confianza del 95% [IC 95%]: 28-42%) pacientes normalizaron la RH. La probabilidad de la normalización de la RH fue del 21% (IC 95%: 13,2-32,4%) 12 meses y del 51,3% (IC 95%: 39,9-63,9%) 24 meses después de iniciar Peg-IFN/RBV en los pacientes con respuesta viral sostenida (RVS), y del 8,3% (IC 95%: 4-16,6%) 12 meses y del 11,3% (IC 95%: 6-20,7%) 24 meses en los sin RVS (p < 0,001). La normalización de la RH en los pacientes con ≥ 7kPa 24 semanas después de finalizar el tratamiento se observó solo en aquellos con RVS. La RVS (hazard ratio [HR]: 6,84; IC 95%: 3,39-13,81) y la ausencia de cirrosis [HR (95%IC): 4.17 (1.69-10)] se asociaron independientemente con la normalización de la RH después de iniciar Peg-IFN/RBV. CONCLUSIONES: La normalización de la RH durante la terapia con Peg-IFN/RBV es más probable y ocurre más temprano en los pacientes con RVS; además, continúa 24 semanas después del fin de tratamiento, pero solo en aquellos con RVS

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.

BACKGROUND & AIMS: This study aimed at developing a predictive algorithm based on interleukin 28B (IL28B) genotype, hepatitis C virus (HCV) genotype, and plasma HCV-RNA load, which could accurately allow us to define the probability of response to pegylated interferon (Peg-IFN) plus ribavirin (RBV) therapy in HIV/HCV-coinfected patients. METHODS: Five hundred and twenty-one treatment-naive HIV-infected patients, who initiated HCV therapy with Peg-IFN/RBV, were analysed in an on-treatment basis. Patients were categorized as unlikely responders, uncertain responders, and anticipated responders (<20%, 20-60%, and >60% probability to achieve SVR, respectively). RESULTS: HCV genotype, baseline HCV-RNA load, and IL28B genotype were confirmed as independent predictors of SVR in a logistic regression analysis. A stepwise algorithm based on these three variables was created based on 321 patients and evaluated in the remaining 200 patients. Unlikely responders included patients with genotype 1 or 4, HCV-RNA load ≥600,000IU/ml, and rs12979860 non-CC (rate of SVR: 17.3%). Anticipated responders were those with HCV genotype 2-3, patients harboring HCV genotype 4 and IL28B CC, as well as those who simultaneously bore HCV genotype 1, HCV-RNA load <600,000IU/ml, and IL28B CC (rate of SVR 74.1%, 77.8%, and 64.4%, respectively). The area under the receiver operating characteristic curve of the model was 0.77 (0.733-0.814). CONCLUSIONS: The combined use of IL28B genotype, HCV genotype, and HCV-RNA load enables to easily identify patients with a high and very low likelihood of SVR. HCV therapy could be deferred in the latter patients, until more effective options are available, at least if they do not show advanced liver fibrosis.

Introducción: Staphylococcus aureus (S. aureus) resistente a meticilina (SARM) se ha convertido en el principal problema de salud pública que causan los microorganismos multirresistentes. Los centros de larga estancia (CLE) constituyen un reservorio importante de SARM. Los objetivos de este estudio fueron determinar la prevalencia y los factores relacionados con la colonización por SARM en los sujetos residentes en CLE en el sur de España. Metodología Estudio transversal descriptivo en el que se incluyeron a los sujetos ingresados en 17 CLE entre el 1 de abril de 2009 y el 30 de junio de 2010. Se realizó una toma de muestra con torunda de ambas fosas nasales con cultivo posterior en medio cromogénico. Si hubo crecimiento bacteriano compatible con estafilococo, se realizó la prueba de coagulasa con el test de aglutinación en látex. Se utilizó un sistema automático para la identificación y sensibilidad del estafilococo aislado. Se construyó un modelo de regresión logística donde la variable primaria del estudio, el ser portador de SARM, fue incluida como variable dependiente y se incluyeron como covariables todas aquellas que en el análisis bivariado hubiesen mostrado un nivel de significación inferior a 0,2. Los individuos fueron clasificados en portador de SARM, S. aureus meticilín-sensible y no portador. Resultados Se incluyeron 744 individuos. Cuatrocientas ochenta y uno (65%) eran mujeres. La edad mediana (Q1-Q3) fue de 81 (74-86) años. Setenta y nueve (10,6%) y 67 (9%) sujetos estaban colonizados por (..) (AU)
Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) has become the most important problem related to multiresistant microorganisms in the health care system. Long-term-care facilities (LTCFs)are one of the main reservoirs of this microorganism. The objective of our study was to determine the prevalence and factors associated with MRSA colonization among subjects living in LTCFs in southern Spain. Methods: During the period from 1st April 2009 to 30th June 2010, all subjects living in 17 LTCFs of our area were included in a cross-sectional study. Patients were screened by using nasal swabs and these were cultured in a chromogenic media. Suspected S. aureus colonies were identified by the latex agglutination test. Testing for antimicrobial identification and susceptibility was performed by an automated system.A logistic regression model was built, in which to be colonized by MRSA was the dependent variable, and covariates were entered if a difference with P < .2 was detected in the bivariate analysis. Residents were classified as MRSA carriers, methicillin-susceptible S. aureus carriers and non-carriers. Results: Seven hundreds and forty-four subjects were included. There were 481 (65%) females. The median (Q1-Q3) age was 81 (74-86) years. Seventy-nine (10.6%) and 67 (9%) were colonized by MRSA and methicillin-susceptible S. aureus, respectively. Significant risk factors for MRSA carriers were recentantibiotic use, previous hospital admission in the last three months, a high comorbidity measured by Charlson index and a history of colonization by MRSA. Conclusions: The prevalence of MRSA colonization in the LTCFs of our area is similar to that described in others European countries. In our institutions, subjects with recent antibiotic use, a high comorbidity, a history of MRSA colonization and a hospital admission in the last three months are more susceptible to be colonized by MRSA (AU)

OBJECTIVE: The aims of this study were to appraise the predictive value of variations in a single-nucleotide polymorphism (SNP) in the low-density lipoprotein receptor (LDLR) gene for sustained virological response (SVR) to pegylated interferon (Peg-IFN) and ribavirin (RBV), as well as to analyze the relationship between LDLR genotype and other predictors of SVR, particularly IL28B genotype, in patients coinfected with HIV and hepatitis C virus (HCV). METHODS: One hundred and eighty-four HIV/HCV-coinfected, treatment-naive patients with chronic HCV infection, who received Peg-IFN and RBV, were included. Variations in the SNP rs14158 and rs12979860 were tested by Taqman PCR assay. RESULTS: Twenty-eight (38%) patients with rs14158 TT/TC and 61 (55%) with CC (P = 0.028) achieved SVR. The rates of SVR in patients with rs14158 TT/TC and with CC harboring HCV 1-4 were 20 and 41% (P = 0.020), respectively, and, in those with HCV genotype 2-3, 75 and 84% (P = 0.513), respectively. Patients with rs14158 CC showed less commonly plasma HCV-RNA load at least 600000 IU/ml (57 vs. 71%, P = 0.047) and lower likelihood of relapse (13 vs. 30%, P = 0.023). In patients with HCV genotype 1-4, the rates of SVR according to the combination of IL28B/LDLR genotypes were: CC/CC = 69%; CC/non-CC: 30%; non-CC/CC: 25%; non-CC/non-CC: 14% (P < 0.001). CONCLUSION: Variations in rs14158 are associated with SVR to Peg-IFN and RBV in HIV/HCV-coinfected patients harboring HCV genotype 1-4. LDLR and IL28B genotypes seem to have a synergistic effect on SVR. The combined use of LDLR and IL28B genotypes in routine clinical practice could enhance the predictive value of IL28B genotype alone.

BACKGROUND: Unexpected cases of severe liver disease in HIV-infected patients have been reported and an association with didanosine (ddI) has been suggested. Transient elastography (TE) might detect patients harbouring such a condition. Our objective was to search for the presence of abnormal liver stiffness (LS) in a cohort of HIV-infected patients without HBV or HCV coinfection and to assess the related factors. METHODS: A cross-sectional prospective study was conducted. LS was assessed by TE in 258 HIV-infected patients without HBV or HCV coinfection and with no evidence of acute hepatotoxicity or other origins of liver disease. LS values > or =7.2 kPa were considered abnormal. Multivariate analyses were performed to identify factors associated with abnormal LS. RESULTS: Abnormal LS was observed in 29 (11.2%) patients. A total of 18 (16.4%) patients previously treated with ddI and 11 (7.4%) of those who never received ddI had LS values > or =7.2 kPa (P=0.02). The prevalence of abnormal LS was higher in patients previously treated with abacavir than in those who had never received abacavir (15 [21.7%] versus 14 [7.4%]; P=0.001). After multivariate analyses, age (adjusted odds ratio [AOR] 1.05, 95% confidence interval [CI] 1.002-1.1; P=0.004) alcohol intake >50 g/day (AOR 7.2, 95% CI 2.6-19.7; P<0.0001), CD4(+) T-cell count <200 cells/ml (AOR 3.4, 95% CI 1.06-11.007; P=0.03), time on ddI treatment (AOR 1.31, 95% CI 1.12-1.52; P=0.001) and previous abacavir exposure (AOR 3.01, 95% CI 1.18-7.67; P=0.02) were independently associated with abnormal LS. CONCLUSIONS: The prevalence of abnormal LS in HIV-infected patients without HBV or HCV coinfection is substantial. Long-term exposure to ddI is a major cause of liver damage in these patients.

Liver-related disease has increased as a cause of hospitalization and in-hospital death in HIV-infected patients since the introduction of highly active antiretroviral therapy (HAART). Better clinical management of these diseases may contribute to decreasing their incidence. Admissions due to liver-related disease in HIV-infected patients in our institution increased from 2.9% in 1998-1999 to 11.3% in 2004-2005 (P = 0.001). In-hospital deaths due to this cause increased from 2.7% in 1998-1999 to 26% in 2002-2003 (P = 0.02), with a subsequent decrease to 22% in 2004-2005. Hospitalization of HIV-infected patients for liver-related disease continues to increase, whereas the rate of in-hospital deaths from this cause appears to have changed since 2003.

En el presente manuscrito se hace un breve resumen de lo que ha sido la historia de la infectología en España. Se consideran cuatro secciones referidas, en primer lugar, a los orígenes de una especialidad fruto de la necesidad de contar con expertos que dieran solución de una forma práctica y moderna a los diferentes problemas planteados por los pacientes con enfermedades infecciosas. En segundo lugar, la aparición del sida al comienzo de los años ochenta dio lugar a un enorme florecimiento en el campo de las enfermedades infecciosas, que trajo consigo la creación de unidades específicas dedicadas no sólo al control de los problemas asociados directamente con la infección por el virus de la inmunodeficiencia humana, sino al tratamiento de las infecciones oportunistas con comitantes. En tercer lugar, en estos últimos años ha despuntado de forma alarmante el problema de la infección nosocomial, problema de plena actualidad que obliga a la presencia de infectólogos expertos en este campo. Finalmente, la emigración y los viajes han requerido de los especialistas en enfermedades infecciosas una formación especial en salud internacional, lo que acrecienta la importancia de la disciplina de infectología (AU)
This paper includes a brief summary of the clinical historyof the diagnosis and treatment of infectious diseases in Spain. Firstly, the origins of a specialty arising from the need for specialists to attend to, in a practical and modern form, the different health problems of patients affected by infectious diseases, are described. Secondly, the appearance of AIDS, at the beginning of the 1980s, prompted the creation of specific units dedicated to the care of problems associated with human immunodeficiency virus (HIV) infection and the concomitant opportunistic infections arising from the immunodeficiency arising from the HIV infection. Thirdly, in the last decades and even today, nosocomial infections have appeared as an alarming problem, needing the presence of specialist physicians in this field. Finally, emigration and international travel require specialists ininfectious diseases with specific expertise in international health, once more highlighting the importance of the specialty of Infectious Diseases (AU)

La hepatopatía ha aumentado como causa de ingreso y muerte intrahospitalaria en pacientes infectados por el virus de la inmunodeficiencia humana (VIH) tras la aparición de la terapia antirretroviral de gran actividad (TARGA). Un mejor manejo clínico de la hepatopatía podría ayudar a disminuir su incidencia. En nuestro centro, los ingresos por hepatopatía aumentaron del 2,9% en 1998-1999 al 11,3% en 2004-2005 (p = 0,001). Las muertes intrahospitalarias debidas a hepatopatía aumentaron del 2,7% en 1998-1999 al 26% en el período 2002-2003 (p = 0,02) y disminuyeron al 22% en 2004-2005. Si bien el número de ingresos por hepatopatía en pacientes infectados por el VIH todavía sigue aumentando, parece que la mortalidad intrahospitalaria ha sufrido un cambio desde 2003 (AU)
Liver-related disease has increased as a cause of hospitalization and in-hospital death in HIV-infected patients since the introduction of highly active antiretroviral therapy (HAART). Better clinical management of these diseases may contribute to decreasing their incidence. Admissions due to liver-related disease in HIV-infected patients in our institution increased from 2.9% in 1998-1999 to 11.3% in 2004-2005 (P = 0.001). In-hospital deaths due to this cause increased from 2.7%in 1998-1999 to 26% in 2002-2003 (P = 0.02), with a subsequent decrease to 22% in 2004-2005. Hospitalization of HIV-infected patients for liver-related disease continues to increase, whereas the rate of in-hospital deaths from this cause appears to have changed since 2003 (AU)

This paper includes a brief summary of the clinical history of the diagnosis and treatment of infectious diseases in Spain. Firstly, the origins of a specialty arising from the need for specialists to attend to, in a practical and modern form, the different health problems of patients affected by infectious diseases, are described. Secondly, the appearance of AIDS, at the beginning of the 1980's, prompted the creation of specific units dedicated to the care of problems associated with human immunodeficiency virus (HIV) infection and the concomitant opportunistic infections arising from the immunodeficiency arising from the HIV infection. Thirdly, in the last decades and even today, nosocomial infections have appeared as an alarming problem, needing the presence of specialist physicians in this field. Finally, emigration and international travel require specialists in infectious diseases with specific expertise in international health, once more highlighting the importance of the specialty of Infectious Diseases.

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.

UNLABELLED: Little is known about the natural history of liver disease in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected subjects under highly active antiretroviral therapy (HAART). The objectives of this study were to obtain information about the mortality, the incidence of hepatic decompensations, and the predictors thereof in this population. In a multicenter cohort study, the time to the first hepatic decompensation and the survival of 1,011 antiretroviral naïve, HIV/HCV-coinfected patients who started HAART and who were followed prospectively were analyzed. After a median (Q1-Q3) follow-up of 5.3 (2.9-7.1) years, 59(5.83%) patients developed a hepatic decompensation and 69 (6.82%) died, 30 (43%) of them because of liver disease. The factors independently associated [HR (95% CI)] with the occurrence of hepatic decompensations were age older than 33 years [2.11 (1.18-3.78)], female sex [2.11 (1.07-4.15)], Centers for Disease Control stage C [2.14 (1.24-3.70)], a diagnosis of cirrhosis at baseline [10.86 (6.02-19.6)], CD4 cell gain lower than 100/mm3 [4.10 (2.18-7.69)] and less than 60% of the follow-up with undetectable HIV viral load [5.23 (2.5-10.93)]. Older age [2.97 (1.18-7.50)], lack of HCV therapy [11.32 (1.44-89.05)], hepatitis D virus coinfection [16.15 (2.45-106.48)], a diagnosis of cirrhosis at recruitment [13.69 (5.55-34.48)], hepatic encephalopathy [62.5 (21.27-200)] and lower CD4 cell gain [3.63 (1.45-9.09)] were associated with mortality due to liver failure. CONCLUSION: End-stage liver disease is the primary cause of death in HIV/HCV-coinfected patients under HAART. Higher increase of CD4 cell counts, lack of markers of serious liver disease and therapy against HCV are factors associated with better hepatic outcome.
