RESUMEN
BACKGROUND & AIMS: Infections by multidrug-resistant bacteria (MDRB) are an increasing healthcare problem worldwide. This study analyzes the incidence, burden, and risk factors associated with MDRB infections after liver transplant(ation) (LT). METHODS: This retrospective, multicenter cohort study included adult patients who underwent LT between January 2017 and January 2020. Risk factors related to pre-LT disease, surgical procedure, and postoperative stay were analyzed. Multivariate logistic regression analysis was performed to identify independent predictors of MDRB infections within the first 90 days after LT. RESULTS: We included 1,045 LT procedures (960 patients) performed at nine centers across Spain. The mean age of our cohort was 56.8 ± 9.3 years; 75.4% (n = 782) were male. Alcohol-related liver disease was the most prevalent underlying etiology (43.2.%, n = 451). Bacterial infections occurred in 432 patients (41.3%) who presented with a total of 679 episodes of infection (respiratory infections, 19.3%; urinary tract infections, 18.5%; bacteremia, 13.2% and cholangitis 11%, among others). MDRB were isolated in 227 LT cases (21.7%) (348 episodes). Enterococcus faecium (22.1%), Escherichia coli (18.4%), and Pseudomonas aeruginosa (15.2%) were the most frequently isolated microorganisms. In multivariate analysis, previous intensive care unit admission (0-3 months before LT), previous MDRB infections (0-3 months before LT), and an increasing number of packed red blood cell units transfused during surgery were identified as independent predictors of MDRB infections. Mortality at 30, 90, 180, and 365 days was significantly higher in patients with MDRB isolates. CONCLUSION: MDRB infections are highly prevalent after LT and have a significant impact on prognosis. Enterococcus faecium is the most frequently isolated multi-resistant microorganism. New pharmacological and surveillance strategies aimed at preventing MDRB infections after LT should be considered for patients with risk factors. IMPACT AND IMPLICATIONS: Multidrug-resistant bacterial infections have a deep impact on morbidity and mortality after liver transplantation. Strategies aimed at improving prophylaxis, early identification, and empirical treatment are paramount. Our study unveiled the prevalence and main risk factors associated with these infections, and demonstrated that gram-positive bacteria, particularly Enterococcus faecium, are frequent in this clinical scenario. These findings provide valuable insights for the development of prophylactic and empirical antibiotic treatment protocols after liver transplantation.

BACKGROUND & AIMS: Life-long hepatocellular carcinoma (HCC) surveillance is recommended after sustained virological response (SVR) in patients with advanced hepatitis C. Since the identification of patients who could be safely discontinued for surveillance is essential, we aimed to identify subsets of patients with low-risk HCC. METHODS: 491 patients with advanced and compensated fibrosis (≥F3) were prospectively followed after achieving SVR with interferon-free therapies. Clinical-biological parameters and liver stiffness measurement (LSM) were performed before starting treatment (ST) and at SVR, and HCC surveillance was carried out. RESULTS: During a median follow-up of 49.8 months, 29 (5.9%) patients developed HCC [incidence rate: 1.6/100 patient-years (PYs)]. Two predictive models based on LSM (Model-A) or FIB-4 score (Model-B) were proposed. Only SVR parameters were included in the models, because they showed a higher accuracy for predicting HCC than ST measurements. Variables independently associated with HCC were LSM (HR, 1.03; 95% CI, 1.01-1.05), age (HR, 1.04; 95% CI, 1.01-1.08) and albumin levels (HR, 0.90; 95% CI, 0.84-0.97) in Model-A, and FIB-4 (HR, 1.22; 95% CI, 1.08-1.37) and albumin (HR, 0.90; 95% CI, 0.84-0.97) in model-B. Both models allow HCC risk stratification, identifying low-risk groups with an HCC incidence rate of 0.16/100 and 0.25/100 PYs, respectively. An overall increased hazard of HCC was observed over time. CONCLUSION: Simple models based on non-invasive markers of liver fibrosis, LSM or FIB-4, together with age and albumin levels at SVR permit to identify subsets of patients with HCC risk clearly <1%/year, for whom HCC surveillance might not be cost-effective.

OBJECTIVE: The effectiveness of transarterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) depends on the selection of suitable patients. The ''Six-and-twelve score" distinguishes three groups of ideal patients with different overall survival, based on the sum of the number and size of tumors. This may impact on clinical practice and trial design. The aim of this study was to assess the reproducibility and prognostic value of the model in western patients treated with Drug-Eluting Beads (DEB)-TACE. METHODS: Observational, retrospective, unicentric study with consecutive compensated patients treated with DEB-TACE from October 2008 to October 2017. Exclusion criteria were Child-Pugh ≥ 8 and DEB-TACE used as a bridge to liver transplantation. RESULTS: 225 HCC consecutive patients were included; BCLC-0/A n=131 (single nodules > 5, n=29) and BCLC-B n=94. The median overall survival (OS) was 27 months (95% CI 23.8-30.2). OS was different between BCLC-0/A vs BCLC-B: 30 vs 24 months (p= 0.03), Child-Pugh A5 vs A6-B7: 30 vs 27 months (p= 0.003). ''Six-and-twelve score" groups discriminated OS: group 1, n=123, 32 months (95% CI 27.5-63.5), group 2, n=101, 24 months (95% CI 19.6-28.4) and group 3, n=1, 27 months (p=0.024). When comparing the three scores, the ''Six-and-twelve score" showed the best discrimination power: C-index 0.603, Akaike's information criterion (AIC) 1.642, likelihood ratio test (LRT) 16.21. CONCLUSION: The ''Six-and-twelve score" is a prognostic tool for patients with HCC treated with DEB-TACE. However, few patients were included in the third group (score >12) and no differences were observed with BCLC, therefore its applicability is limited. .

BACKGROUND AND AIM: reduction in calcineurin inhibitor levels is considered crucial to decrease the incidence of kidney dysfunction in liver transplant (LT) recipients. The aim of this study was to evaluate the safety and impact of everolimus plus reduced tacrolimus (EVR + rTAC) vs. mycophenolate mofetil plus tacrolimus (MMF + TAC) on kidney function in LT recipients from Spain. METHODS: the REDUCE study was a 52-week, multicenter, randomized, controlled, open-label, phase 3b study in de novo LT recipients. Eligible patients were randomized (1:1) 28 days post-transplantation to receive EVR + rTAC (TAC levels ≤â¯5 ng/mL) or to continue with MMF + TAC (TAC levels = 6-10 ng/mL). Mean estimated glomerular filtration rate (eGFR), clinical benefit in renal function, and safety were evaluated. RESULTS: in the EVR + rTAC group (nâ¯=â¯105), eGFR increased from randomization to week 52 (82.2 [28.5] mL/min/1.73â¯m2 to 86.1 [27.9] mL/min/1.73â¯m2) whereas it decreased in the MMF + TAC (nâ¯=â¯106) group (88.4â¯[34.3]â¯mL/min/1.73 m2 to 83.2â¯[25.2]â¯mL/min/1.73 m2), with significant (pâ¯<â¯0.05) differences in eGFR throughout the study. However, both groups had a similar clinical benefit regarding renal function (improvement in 18.6 % vs. 19.1 %, and stabilization in 81.4 % vs. 80.9 % of patients in the EVR + rTAC vs. MMF + TAC groups, respectively). There were no significant differences in the incidence of acute rejection (5.7 % vs. 3.8 %), deaths (5.7 % vs. 2.8 %), and serious adverse events (51.9 % vs. 44.0 %) between the 2 groups. CONCLUSION: EVR + rTAC allows a safe reduction in tacrolimus exposure in de novo liver transplant recipients, with a significant improvement in eGFR but without significant differences in renal clinical benefit 1 year after liver transplantation.

BACKGROUND & AIMS: The incidence and outcomes of coronavirus disease 2019 (COVID-19) in immunocompromised patients are a matter of debate. METHODS: We performed a prospective nationwide study including a consecutive cohort of liver transplant patients with COVID-19 recruited during the Spanish outbreak from 28 February to 7 April, 2020. The primary outcome was severe COVID-19, defined as the need for mechanical ventilation, intensive care, and/or death. Age- and gender-standardised incidence and mortality ratios (SIR and SMR) were calculated using data from the Ministry of Health and the Spanish liver transplant registry. Independent predictors of severe COVID-19 among hospitalised patients were analysed using multivariate Cox regression. RESULTS: A total of 111 liver transplant patients were diagnosed with COVID-19 (SIR = 191.2 [95% CI 190.3-192.2]). The epidemiological curve and geographic distribution overlapped widely between the liver transplant and general populations. After a median follow-up of 23 days, 96 patients (86.5%) were admitted to hospital and 22 patients (19.8%) required respiratory support. A total of 12 patients were admitted to the ICU (10.8%). The mortality rate was 18%, which was lower than in the matched general population (SMR = 95.5 [95% CI 94.2-96.8]). Overall, 35 patients (31.5%) met criteria of severe COVID-19. Baseline immunosuppression containing mycophenolate was an independent predictor of severe COVID-19 (relative risk = 3.94; 95% CI 1.59-9.74; p = 0.003), particularly at doses higher than 1,000 mg/day (p = 0.003). This deleterious effect was not observed with calcineurin inhibitors or everolimus and complete immunosuppression withdrawal showed no benefit. CONCLUSIONS: Being chronically immunosuppressed, liver transplant patients have an increased risk of acquiring COVID-19 but their mortality rates are lower than the matched general population. Upon hospital admission, mycophenolate dose reduction or withdrawal could help in preventing severe COVID-19. However, complete immunosuppression withdrawal should be discouraged. LAY SUMMARY: In liver transplant patients, chronic immunosuppression increases the risk of acquiring COVID-19 but it could reduce disease severity. Complete immunosuppression withdrawal may not be justified. However, mycophenolate withdrawal or temporary conversion to calcineurin inhibitors or everolimus until disease resolution could be beneficial in hospitalised patients.

INTRODUCTION: Although alcohol cessation is the only effective treatment for alcohol-related liver disease, few data exist concerning its influence on the risk of hepatocellular carcinoma (HCC). We aimed to evaluate the effect of alcohol abstinence on the incidence of HCC in patients with alcohol-related cirrhosis. METHODS: We studied 727 patients with alcohol-related cirrhosis (247 with compensated disease and 480 with previous decompensation) who were included in a surveillance program for the early detection of HCC and prospectively followed. Baseline clinical and biological parameters and alcohol consumption during follow-up were recorded. Abstinence was defined as the absence of any alcohol use. RESULTS: During follow-up (median 54 months), 354 patients (48.7%) remained abstinent and 104 developed HCC (2.3 per 100 person-years). Factors independently associated with the risk of HCC among patients with previous decompensation were age, male gender, and aspartate aminotransferase, whereas abstinence was not linked to a reduced risk (hazard ratio 0.95; 95% confidence interval 0.59-1.52). However, among patients without previous decompensation, prothrombin activity and abstinence were independently associated with the risk of HCC. Abstinent patients had a significant decrease in the risk of developing tumor (hazard ratio 0.35; 95% confidence interval 0.13-0.94). These results did not change after applying a competing risk analysis where death and liver transplantation were considered as competing events. DISCUSSION: Alcohol abstinence reduced the risk of HCC in patients with alcohol-related cirrhosis, but only in those without a history of decompensated disease. This finding emphasizes the need for an early diagnosis of alcohol-related liver disease and for implementing strategies leading to an increase in the rate of achieving and maintaining abstinence among this population.

Safety of regorafenib in hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT) has been recently demonstrated. We aimed to assess the survival benefit of regorafenib compared with best supportive care (BSC) in LT patients after sorafenib discontinuation. This observational multicenter retrospective study included LT patients with HCC recurrence who discontinued first-line sorafenib. Group 1 comprised regorafenib-treated patients, whereas the control group was selected among patients treated with BSC due to unavailability of second-line options at the time of sorafenib discontinuation and who were sorafenib-tolerant progressors (group 2). Primary endpoint was overall survival (OS) of group 1 compared with group 2. Secondary endpoints were safety and OS of sequential treatment with sorafenib + regorafenib/BSC. Among 132 LT patients who discontinued sorafenib included in the study, 81 were sorafenib tolerant: 36 received regorafenib (group 1) and 45 (group 2) received BSC. Overall, 24 (67%) patients died in group 1 and 40 (89%) in group 2: the median OS was significantly longer in group 1 than in group 2 (13.1 versus 5.5 months; P < 0.01). Regorafenib treatment was an independent predictor of reduced mortality (hazard ratio, 0.37; 95% confidence interval [CI], 0.16-0.89; P = 0.02). Median treatment duration with regorafenib was 7.0 (95% CI, 5.5-8.5) months; regorafenib dose was reduced in 22 (61%) patients for adverse events and discontinued for tumor progression in 93% (n = 28). The median OS calculated from sorafenib start was 28.8 months (95% CI, 17.6-40.1) in group 1 versus 15.3 months (95% CI, 8.8-21.7) in group 2 (P < 0.01). Regorafenib is an effective second-line treatment after sorafenib in patients with HCC recurrence after LT.

BACKGROUND AND AIMS: The effectiveness of systemic treatment in advanced hepatocellular carcinoma (HCC) depends on the selection of patients, management of cirrhosis complications and expertise to treat adverse events. The aims of the study are to assess the frequency and management of cardiovascular events in HCC patients treated with sorafenib (SOR) and to create a scale to predict the onset of major adverse cardiovascular events (MACE). METHOD: Observational retrospective study with consecutive HCC patients treated with SOR between 2007 and 2019 in a western centre. In order to classify cardiovascular risk pre-SOR, we designed the CARDIOSOR scale with age, hypertension, diabetes, dyslipidaemia and peripheral vascular disease. Other adverse events, dosing and outcome data were collected during a homogeneous protocolled follow-up. RESULTS: Two hundred ninety-nine patients were included (219 BCLC-C). The median overall survival was 11.1 months (IQR 5.6-20.5), and duration of treatment was 7.4 months (IQR 3.3-14.7). Seventeen patients (6%) stopped SOR due to cardiovascular event. Thirty-three patients suffered MACE (7 heart failure, 11 acute coronary syndrome, 12 cerebrovascular accident and 8 peripheral vascular ischemia); 99 had a minor cardiovascular event, mainly hypertension (n = 81). Age was the only independent factor associated to MACE (HR 1.07; 95% CI 1.03-1.12; P = .002). The CARDIOSOR scale allows to identify the group of patients with higher risk of MACE (sHR 3.4; 95% CI 1.4-6.7; P = .04). CONCLUSION: The incidence of cardiovascular events in HCC patients treated with SOR is higher than expected. Multidisciplinary approach and clinical tools like CARDIOSOR scale could be helpful to manage these patients.

BACKGROUND: A single-centre cohort study was performed to identify the independent factors associated with the overall survival (OS) of hepatocellular carcinoma (HCC) patients treated with transarterial chemoembolization with drug-eluting beads (DEB-TACE). METHODS: A total of 216 HCC patients who underwent DEB-TACE from October 2008 to October 2015 at a tertiary hospital were consecutively recruited. The analysis of prognostic factors associated with overall survival after DEB-TACE, stressing the role of post-TACE events, was performed. RESULTS: The objective response (OR) rate (Modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria) to the first DEB-TACE (DEB-TACE-1) was 70.3%; the median OS from DEB-TACE-1 was 27 months (95% confidence interval (CI), 24-30). In the multivariate analysis, tumor size, AFP < 100 ng/mL and serum alkaline phosphatase were independent factors for survival following DEB-TACE-1. The most important clinical event associated with poor survival was the development of early ascites after DEB-TACE-1 (median OS, 17 months), which was closely related to the history of ascites, albumin and hemoglobin but not to tumour load or to response to therapy. CONCLUSIONS: Early ascites post-DEB-TACE is associated with the survival of patients despite adequate liver function and the use of a supra-selective technical approach. History of ascites, albumin and hemoglobin are major determinants of the development of early ascites post-DEB-TACE.

BACKGROUND: the development of interferon-free regimens, based on direct acting antivirals (DAAs) has revolutionized the treatment of hepatitis C virus (HCV) infection. AIMS: to determine if there have been changes in the characteristics of hospital admissions due to decompensated cirrhosis in a general hospital since the introduction of DAAs. PATIENTS AND METHODS: this was a prospective study of all hospital admissions due to decompensated cirrhosis during two periods: October 2012-October 2014 (P-I) and July 2016-July 2018 (P-II). Clinical and demographic variables were collected and standard statistical methods were used for the analysis. RESULTS: there were 746 hospital admissions; 347 in P-I and 399 in P-II. P-I patients were younger (59 vs 63 years; p = 0.034), while the proportion of admissions due to HCV-cirrhosis was lower in P-II (15.8 % vs 21.6 %; p = 0.041). There were no significant differences in the proportion of admissions due to other etiologies of cirrhosis between both periods. Patients in the P-II group presented an active viral infection (57.1 vs 97.3 %; p = 0.001) less frequently and had a higher rate of excessive alcohol consumption (55.5 vs 30.7 %; p = 0.003) when admitted, while HIV co-infection was less frequent (1.6 % vs 10.7 %; p = 0.039). CONCLUSION: the proportion of admissions due to decompensated HCV-related cirrhosis has decreased by almost 30 % since the introduction of the DAA. In addition, the characteristics of patients admitted have changed since the application of interferon-free regimens.

BACKGROUND AND AIM: Surveillance for hepatocellular carcinoma (HCC) intends to detect tumors at an early stage to improve survival. The study aims were to assess the frequency and risk factors associated with HCC surveillance failure. METHODS: The study analyzed data from 188 consecutive patients diagnosed with HCC within a surveillance program conducted among 1,242 cirrhotic patients and based on ultrasonography and alpha-fetoprotein (AFP) testing every 3 or 6 months. Program failure was defined as the detection of HCC exceeding the Milan criteria. Variables recorded at entry into the program, during follow-up and at HCC diagnosis, were analyzed. RESULTS: At diagnosis, 50 (26.6%) HCC tumors were beyond the Milan criteria. In univariate analysis, Child-Pugh B at entry (P = 0.03), development of complications of portal hypertension before tumor diagnosis (P = 0.03), and failure to complete the prior screening round (P = 0.02), Child-Pugh B/C (P = 0.001) and AFP ≥ 100 ng/mL (P = 0.03) at diagnosis, were associated with failure. In multivariate analysis, only Child-Pugh B/C (hazard ratio, 3.18; 95% confidence interval, 1.66-6.10, P < 0.001) and AFP ≥ 100 ng/mL, both at diagnosis (hazard ratio, 2.80; 95% confidence interval, 1.37-5.71, P = 0.005), were independently associated with failure. Survival was higher among patients with tumors within the Milan criteria than those with program failure (33.9 vs 7.6 months, P < 0.001). CONCLUSIONS: Approximately 25% of HCC cases diagnosed among patients included in a surveillance program were beyond the Milan criteria. Child-Pugh B/C and AFP ≥ 100 ng/mL at diagnosis were associated with program failure. However, Child-Pugh B at entry and development of liver-related complications during follow-up can be early predictors of failure.

INTRODUCTION: chronic kidney disease is a frequent complication after liver transplantation. The use of calcineurin inhibitors is one of the causes of this complication. Current immunsuppression regimens that reduce the use of calcineurin inhibitors may be associated with an improved preservation of renal function. OBJECTIVE: the study aimed to assess the evolution of renal function after liver transplantation in the current routine clinical practice. METHODS: an observational, prospective, multicenter study in adult liver transplant recipients was performed. Two hundred and thirty patients with a good renal function before transplantation were assessed six months post-transplantation (baseline) and every six months until month 30. RESULTS: at baseline, 32% of the patients had a reduction in the glomerular filtration rate below < 60 ml/min/1.73 m2. The mean glomerular filtration rate increased from 72.3 to 75.6 ml/min/1.73 m2 at baseline and month 30 respectively (p < 0.01). The mean serum creatinine levels (mg/dl) decreased from 1.13 to 1.09 (p < 0.01). The percentage of patients with stage 3 chronic kidney disease decreased from 31.7% to 26.4%, whereas the percentage of patients with stage 4 remained unchanged (0.4% at baseline and 0.5% at month 30). No patients progressed to end-stage kidney disease that required dialysis or renal transplantation. CONCLUSION: in the routine clinical practice, a moderate deterioration of renal function is frequent after liver transplantation. However, advanced chronic kidney disease is infrequent in patients with a good pre-transplant renal function.

BACKGROUND: Patient adherence to screening for hepatocellular carcinoma (HCC) is not well known. Our aims were to analyze the adherence to a surveillance program in a prospective cohort of cirrhotic patients and to examine its association with HCC stage at diagnosis. MATERIALS AND METHODS: A total of 770 patients with cirrhosis were examined semiannually by ultrasound and alpha-fetoprotein at a tertiary center. We collected data on 17 variables at baseline. Suboptimal adherence was defined as failure to complete 2 consecutive screening rounds. RESULTS: Over a median follow-up period of 42.0 months (interquartile range: 60.0), 125 patients (16.2%) had suboptimal adherence. Active or previous intravenous drug use [hazard ratio (HR), 5.33; 95% confidence interval (CI), 3.07-9.23], active alcohol consumption (HR, 3.03; 95% CI, 2.03-4.51), absence of liver decompensation before the inclusion in the program (HR, 1.65; 95% CI, 1.07-2.55) and aspartate transaminase/alanine transaminase ratio ≥1.6 (HR, 1.82; 95% CI, 1.23-2.70) were independent predictors of suboptimal adherence. Compared with those with optimal adherence, patients with suboptimal adherence had a more advanced HCC stage at diagnosis (P=0.015), they were less frequently treated with curative intention (P=0.078) and survived less (median: 14.2 mo; IQR: 36.0 vs. 22.7 mo; IQR: 47.4; P=0.160), although these differences were not significant. CONCLUSIONS: The adherence to the process of HCC surveillance can be considered as adequate among cirrhotic patients. Active alcohol consumption and a history of intravenous drug use are the strongest predictors of suboptimal adherence. These patients have a more advanced HCC stage at diagnosis and tend to be less frequently treated with curative intention.

The recent availability of commercial techniques for the quantification of the hepatitis B surface antigen (HBsAg) has revived interest in this antigen. In recent years, the antigen's potential as a biomarker of the natural history of the disease and its response to antiviral treatment has been assessed. HBsAg serum values reflect the transcriptional activity of cccDNA; reading these values could therefore complement the reading of hepatitis B virus (HBV) DNA in the categorization of the various phases of chronic HBV infection. During its natural history, HBsAg values progressively decrease from the immune-tolerant phase to the inactive carrier phase. For patients who are HBeAg-negative, the combined reading of HBV DNA and HBsAg can be useful for differentiating inactive carriers from patients with chronic HBeAg-negative hepatitis, for stratifying the risk of developing hepatocarcinoma and for predicting HBsAg clearance.

BACKGROUND AND AIM: Recommendations on pregnancy, lactation, and contraception in women with Wilson disease are briefly stated in international guidelines but are not entirely homogeneous. Data regarding the management of these special events among patients with Wilson disease in Spain are lacking. We used the Wilson Registry platform of the Spanish Association for the Study of the Liver to question patients on their reproductive and gestational lives. METHODS: This was a multicentre ambispective study including adult women with Wilson disease in the Spanish Wilson Registry interviewed about their contraception, childbearing, pregnancy, and lactation experiences. Clinical and analytical data were extracted from the registry. RESULTS: The study included 92 women from 17 centres in Spain. Most (63%) reported having a previous pregnancy history. The rate of spontaneous miscarriages was 21.6%, mainly occurring in the first trimester and up to one third among undiagnosed patients. Most pregnant women received chelator therapy during pregnancy, but dose reduction was recommended in less than 10%. After delivery, artificial lactation predominated (60.3%) and its use was mainly based on physician's recommendations (68%). Up to 40% of the women included reported some concerns about their reproductive lives, mainly related to the potential drug toxicity to their children. Most of the patients considered the information given by specialists to be sufficient. CONCLUSION: Gestational management among women with Wilson disease in Spain was found to be highly heterogeneous and frequently different from what is described in international guidelines. Education on rare liver diseases should be a priority for scientific societies in order to homogenize patient follow-up and recommendations.
RESUMEN
Chronic hepatitis B is still a major public health problem, aggravated by the growing phenomenon of immigration from areas with a high prevalence of infection with this virus. In the last few years, marked progress has been achieved in diagnostic methods, knowledge of the natural history of the disease and in therapeutic options, including liver transplantation, which has improved survival in these patients. These advances have been accompanied by an increase in the complexity of decision making. Six treatments have currently been approved for hepatitis B, including two interferon formulations--standard and pegylated--and four neucleos(t)ide analogs, lamivudine, adefovir, entecavir and telbivudine, as well as two further drugs that are used in patients coinfected with HIV, tenofovir and emtricitabine. However, none of the current treatments is able to eradicate the virus and consequently prolonged treatments are often required with the consequent risk of generating resistance. For this reason, as well as the heterogeneity of the natural history of the disease, there is a lack of consensus on the indications for treatment and the parameters in which treatment should be based, the most suitable drug or drug combination, and the criteria to be used to continue, modify or suspend treatment. Therefore, despite the enormous progress made, numerous questions remain that make the clinical management of these patients a major challenge.
