Analysis of the costs and cost-effectiveness of the guidelines recommended by the 2018 GESIDA/Spanish National AIDS Plan for initial antiretroviral therapy in HIV-infected adults.

BACKGROUND: The GESIDA/National AIDS Plan expert panel recommended preferred regimens (PR), alternative regimens (AR) and other regimens (OR) for antiretroviral treatment (ART) as initial therapy in HIV-infected patients for 2018. The objective of this study was to evaluate the costs and the efficiency of initiating treatment with PR and AR. METHODS: Economic assessment of costs and efficiency (cost-effectiveness) based on decision tree analyses. Effectiveness was defined as the probability of reporting a viral load <50copies/mL at week 48, in an intention-to-treat analysis. Cost of initiating treatment with an ART regimen was defined as the costs of ART and its consequences (adverse effects, changes of ART regimen, and drug-resistance studies) over the first 48 weeks. The payer perspective (National Health System) was applied considering only differential direct costs: ART (official prices), management of adverse effects, studies of resistance, and HLA B*5701 testing. The setting was Spain and the costs correspond to those of 2018. A deterministic sensitivity analysis was conducted, building three scenarios for each regimen: base case, most favourable and least favourable. RESULTS: In the base-case scenario, the cost of initiating treatment ranges from 6788 euros for TAF/FTC/RPV (AR) to 10,649 euros for TAF/FTC+RAL (PR). The effectiveness varies from 0.82 for TAF/FTC+DRV/r (AR) to 0.91 for TAF/FTC+DTG (PR). The efficiency, in terms of cost-effectiveness, ranges from 7814 to 12,412 euros per responder at 48 weeks, for ABC/3TC/DTG (PR) and TAF/FTC+RAL (PR), respectively. CONCLUSION: Considering ART official prices, the most efficient regimen was ABC/3TC/DTG (PR), followed by TAF/FTC/RPV (AR) and TAF/FTC/EVG/COBI (AR).

Costs and cost-efficacy analysis of the 2017 GESIDA/Spanish National AIDS Plan recommended guidelines for initial antiretroviral therapy in HIV-infected adults.

INTRODUCTION: GESIDA and the Spanish National AIDS Plan panel of experts have recommended preferred (PR), alternative (AR) and other regimens (OR) for antiretroviral therapy (ART) as initial therapy in HIV-infected patients for 2017. The objective of this study was to evaluate the costs and the efficiency of initiating treatment with PR and AR. METHODS: Economic assessment of costs and efficiency (cost-efficacy) based on decision tree analyses. Efficacy was defined as the probability of reporting a viral load <50copies/mL at week 48, in an intention-to-treat analysis. Cost of initiating treatment with an ART regimen was defined as the costs of ART and its consequences (adverse effects, changes of ART regimen and drug resistance studies) during the first 48 weeks. The payer perspective (National Health System) was applied considering only differential direct costs: ART (official prices), management of adverse effects, resistance studies and HLA B*5701 screening. The setting was Spain and the costs correspond to those of 2017. A deterministic sensitivity analysis was conducted, building three scenarios for each regimen: base case, most favourable and least favourable. RESULTS: In the base case scenario, the cost of initiating treatment ranged from 6882 euro for TFV/FTC/RPV (AR) to 10,904 euros for TFV/FTC+RAL (PR). The efficacy varied from 0.82 for TFV/FTC+DRV/p (AR) to 0.92 for TAF/FTC/EVG/COBI (PR). The efficiency, in terms of cost-efficacy, ranged from 7923 to 12,765 euros per responder at 48 weeks, for ABC/3TC/DTG (PR) and TFV/FTC+RAL (PR), respectively. CONCLUSION: Considering ART official prices, the most efficient regimen was ABC/3TC/DTG (PR), followed by TFV/FTC/RPV (AR) and TAF/FTC/EVG/COBI (PR).

Costs and cost-efficacy analysis of the 2016 GESIDA/Spanish AIDS National Plan recommended guidelines for initial antiretroviral therapy in HIV-infected adults.

INTRODUCTION: GESIDA and the AIDS National Plan panel of experts suggest preferred (PR), alternative (AR), and other regimens (OR) for antiretroviral treatment (ART) as initial therapy in HIV-infected patients for the year 2016. The objective of this study is to evaluate the costs and the efficacy of initiating treatment with these regimens. METHODS: Economic assessment of costs and efficiency (cost/efficacy) based on decision tree analyses. Efficacy was defined as the probability of reporting a viral load <50copies/mL at week 48 in an intention-to-treat analysis. Cost of initiating treatment with an ART regimen was defined as the costs of ART and its consequences (adverse effects, changes of ART regimen, and drug resistance studies) during the first 48 weeks. The payer perspective (National Health System) was applied, only taking into account differential direct costs: ART (official prices), management of adverse effects, studies of resistance, and HLA B*5701 testing. The setting is Spain and the costs correspond to those of 2016. A sensitivity deterministic analysis was conducted, building three scenarios for each regimen: base case, most favourable, and least favourable. RESULTS: In the base case scenario, the cost of initiating treatment ranges from 4663 Euros for 3TC+LPV/r (OR) to 10,894 Euros for TDF/FTC+RAL (PR). The efficacy varies from 0.66 for ABC/3TC+ATV/r (AR) and ABC/3TC+LPV/r (OR), to 0.89 for TDF/FTC+DTG (PR) and TDF/FTC/EVG/COBI (AR). The efficiency, in terms of cost/efficacy, ranges from 5280 to 12,836 Euros per responder at 48 weeks, for 3TC+LPV/r (OR), and RAL+DRV/r (OR), respectively. CONCLUSION: Despite the overall most efficient regimen being 3TC+LPV/r (OR), among the PR and AR, the most efficient regimen was ABC/3TC/DTG (PR). Among the AR regimes, the most efficient was TDF/FTC/RPV.

Executive summary: Prevention and treatment of opportunistic infections and other coinfections in HIV-infected patients: May 2015.

Opportunistic infections continue to be a cause of morbidity and mortality in HIV-infected patients. They often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an opportunistic infection. The present article is an executive summary of the document that updates the previous recommendations on the prevention and treatment of opportunistic infections in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome. This document is intended for all professionals who work in clinical practice in the field of HIV infection.

Prevention and treatment of opportunistic infections and other coinfections in HIV-infected patients: May 2015.

Despite the huge advance that antiretroviral therapy represents for the prognosis of infection by the human immunodeficiency virus (HIV), opportunistic infections (OIs) continue to be a cause of morbidity and mortality in HIV-infected patients. OIs often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an OI. The present article updates our previous guidelines on the prevention and treatment of various OIs in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome.

Rate and predictors of progression in elite and viremic HIV-1 controllers.

BACKGROUND: The proportion of HIV controllers developing virologic, immunological or clinical progression and the baseline predictors of these outcomes have not been assessed in large cohorts. METHODS: A multicenter cohort of HIV controllers was followed from baseline (the first of the three HIV-1 RNA levels < 50 in elite controller or from 50 to 2000 copies/ml in viremic controllers) up to August 2011, to the development of a progression event (loss of viral load control, CD4 decline, AIDS or death) or to the censoring date (lost to follow-up or initiation of antiretroviral therapy). Predictive models of progression at baseline and a risk score for the combined HIV-1 progression end point were calculated. RESULTS: Four hundred and seventy-five HIV-1 controllers of whom 204 (42.9%) were elite controller with 2972 person-years of follow-up were identified. One hundred and forty-one (29.7%) patients lost viral load control. CD4 cell count declined in 229 (48.2%) patients. Thirteen patients developed an AIDS event and four died. Two hundred and eighty-seven (60.4%) developed a combined HIV-1 progression. Baseline predictors for the progression end points and for elite and viremic controller patients were very similar: risk for HIV-1 acquisition, baseline calendar year, CD4 nadir, viral load before baseline and hepatitis C virus coinfection. The probability of a combined HIV-1 progression at 5 years was 70% for elite controllers with the highest score compared with 13% for those with the lowest. CONCLUSION: HIV-1 disease progression in elite and viremic controllers is frequent. We propose a baseline clinical score to easily classify these patients according to risk of progression. This score could be instrumental for taking clinical decisions and performing pathogenic studies.

Clinical, epidemiological and treatment failure data among HIV-1 non-B-infected patients in the Spanish AIDS Research Network Cohort.

INTRODUCTION: The prevalence of HIV-1 non-B variants is increasing in Spain, showing a higher number of transmitted drug resistance mutations (TDR) since 2002. This study presents the features of non-B-infected patients enrolled in the cohort of antiretroviral treatment (ART) naïve HIV-infected patients included in the Research Network on HIV/AIDS (CoRIS). METHODS: The study includes a selected group of HIV-1 non-B-infected subjects from 670 subjects with pol sequences collected from 2004 to 2008 in the CoRIS cohort. Epidemiological-clinical-virological data were analyzed since cohort entry until October 2011, considering the presence or absence of treatment failure (TF). RESULTS: Eighty two non-B infected subjects with known HIV-1 variants were selected from 2004 to 2008 in the CoRIS cohort, being mainly female, immigrants, infected by recombinant viruses, and by heterosexual route. They had an intermediate TDR rate (9.4%), a high rate of TF (25.6%), of losses to follow-up (35%), of coinfections (32.9%), and baseline CD4+ counts ≥350cells/mm(3) (61.8%). Non-B subjects with TF showed higher rates of heterosexual infection (85.7% vs. 69.5%, p<0.05), tuberculosis (30.8% vs. 9.1%, p=0.10) and hepatitis C (23.8% vs. 13.9%, p=0.34) coinfections and lower rates of syphilis (0% vs. 21.9%, p<0.05), and had more frequently received first-line ART including protease inhibitors (PIs) than patients without TF (70% vs. 30%, p<0.05). Interestingly, infection with non-B variants reduced the risk of TDR to nucleoside reverse transcriptase inhibitors and increased the risk to PIs. CONCLUSION: HIV-1 non-B-infected patients in Spain had a particular epidemiological and clinical profile that should be considered during their clinical management.

Extremely High Mutation Rate of HIV-1 In Vivo.

Rates of spontaneous mutation critically determine the genetic diversity and evolution of RNA viruses. Although these rates have been characterized in vitro and in cell culture models, they have seldom been determined in vivo for human viruses. Here, we use the intrapatient frequency of premature stop codons to quantify the HIV-1 genome-wide rate of spontaneous mutation in DNA sequences from peripheral blood mononuclear cells. This reveals an extremely high mutation rate of (4.1 ± 1.7) × 10-3 per base per cell, the highest reported for any biological entity. Sequencing of plasma-derived sequences yielded a mutation frequency 44 times lower, indicating that a large fraction of viral genomes are lethally mutated and fail to reach plasma. We show that the HIV-1 reverse transcriptase contributes only 2% of mutations, whereas 98% result from editing by host cytidine deaminases of the A3 family. Hypermutated viral sequences are less abundant in patients showing rapid disease progression compared to normal progressors, highlighting the antiviral role of A3 proteins. However, the amount of A3-mediated editing varies broadly, and we find that low-edited sequences are more abundant among rapid progressors, suggesting that suboptimal A3 activity might enhance HIV-1 genetic diversity and pathogenesis.

Association of baseline CD4+ cell count and HIV-RNA on sustained virologic response to interferon-ribavirin in HIV/HCV coinfected patients.

UNLABELLED: BACKGROUND AND RATIONALE FOR THE STUDY: We assessed the association of CD4+ T-cell counts and HIV-RNA on sustained viral response (SVR) after therapy with pegylated interferon and ribavirin (PR) in HIV/HCV coinfected patients. We examined two large cohorts of coinfected patients treated with PR in Spain between 2000 and 2008. SVR was defined as undetectable HCV-RNA at 24 weeks after the end of PR. RESULTS: We studied 1682 patients, of whom 38% achieved SVR. Baseline factors independently associated with reduced odds of SVR included genotype 1 or 4, HCV-RNA > 500,000 IU/mL, advanced liver fibrosis, CDC clinical category C, and detectable HIV-RNA. By multivariate logistic regression analysis, we found that, in comparison with patients with combination antiretroviral therapy (cART) and undetectable HIV-RNA, the odds ratio [95% confidence interval (CI)] of SVR was 0.56 (0.41-0.78) for cART and detectable HIV-RNA, 0.86 (0.56-2.57) for no-cART and detectable HIV-RNA, and 1.38 (0.74-2.57) for no-cART and undetectable HIV-RNA. CONCLUSIONS: Detectable HIV-RNA, but not CD4+ T-cell count, was associated with reduced odds of SVR. However, this finding was only confirmed for cART and detectable HIV-RNA, raising the question as whether this represents a true association of HIV-RNA on response to PR or a spurious association due to poor adherence to treatment.

Comparison of the prognostic value of liver biopsy and FIB-4 index in patients coinfected with HIV and hepatitis C virus.

BACKGROUND: We compared the prognostic value of liver biopsy (LB) and FIB-4 index in patients with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection. METHODS: We studied patients from the Grupo de Estudio del SIDA 3603 study cohort, in whom fibrosis was evaluated at baseline using both LB (Metavir score) and FIB-4 index. We assessed overall death (OD) and liver-related events (LREs), defined as decompensation or hepatocellular carcinoma, whichever occurred first. We used receiver operating characteristic (ROC) curves to determine the ability of LB and FIB-4 to predict outcomes. We also assessed the association between advanced fibrosis-LB (F3 or greater) or FIB-4 (≥3.25)-and outcomes using multivariate Cox regression analysis. RESULTS: The study sample comprised 903 patients (328 with sustained virologic response [SVR]). Baseline fibrosis by LB was as follows: F0, n = 71; F1, n = 242; F2, n = 236; F3, n = 236; F4, n = 118. Fibrosis by FIB-4 was as follows: ≤1, n = 148; >1 to <3.25, n = 597; ≥3.25, n = 158. After a median follow-up of 62 months, there were 46 deaths and 71 LREs. The area under the ROC curves for OD/LREs was 0.648 and 0.742 for LB and FIB-4, respectively (P = .006). Similar results were found for patients without SVR and for OD and LREs separately. The adjusted hazard ratios of OD or LRE were 1.740 (95% confidence interval [CI], 1.119-2.7.06; P = .014) for advanced fibrosis assessed by LB and 3.896 (95% CI, 2.463-6.160; P < .001) assessed by FIB-4. CONCLUSIONS: FIB-4 outperformed LB as a predictor of OD and LRE. These findings are of relevance for clinical practice and research and call into question the role of LB as a gold standard for assessing prognosis in HIV/HCV coinfection.

Executive summary of the consensus document on metabolic disorders and cardiovascular risk in patients with HIV infection.

The importance of the metabolic disorders and their impact on patients with HIV infection requires an individualized study and continuous updating. HIV patients have the same cardiovascular risk factors as the general population. The HIV infection per se increases the cardiovascular risk, and metabolic disorders caused by some antiretroviral drugs are added risk factors. For this reason, the choice of drugs with a good metabolic profile is essential. The most common metabolic disorders of HIV infected-patients (insulin resistance, diabetes, hyperlipidemia or osteopenia), as well as other factors of cardiovascular risk, such as hypertension, should also be dealt with according to guidelines similar to the general population, as well as insisting on steps to healthier lifestyles. The aim of this document is to provide a query tool for all professionals who treat HIV-patients and who may present or display any metabolic disorders listed in this document.

[Consensus statement on metabolic disorders and cardiovascular risks in patients with human immunodeficiency virus]. / Documento de consenso sobre alteraciones metabólicas y riesgo cardiovascular en pacientes con infección por el virus de la inmunodeficiencia humana.

OBJECTIVE: This consensus document is an update of metabolic disorders and cardiovascular risk (CVR) guidelines for HIV-infected patients. METHODS: This document has been approved by an expert panel of GEAM, SPNS and GESIDA after reviewing the results of efficacy and safety of clinical trials, cohort and pharmacokinetic studies published in biomedical journals (PubMed and Embase) or presented in medical scientific meetings. Recommendation strength and the evidence in which they are supported are based on the GRADE system. RESULTS: A healthy lifestyle is recommended, no smoking and at least 30min of aerobic exercise daily. In diabetic patients the same treatment as non-HIV infected patients is recommended. HIV patients with dyslipidemia should be considered as high CVR, thus its therapeutic objective is an LDL less than 100mg/dL. The antihypertensive of ACE inhibitors and ARAII families are better tolerated and have a lower risk of interactions. In HIV-patients with diabetes or metabolic syndrome and elevated transaminases with no defined etiology, the recommended is to rule out a hepatic steatosis Recommendations for action in hormone alterations are also updated. CONCLUSIONS: These new guidelines update previous recommendations regarding all those metabolic disorders involved in CVR. Hormone changes and their management and the impact of metabolic disorders on the liver are also included.

Consensus document on the management of renal disease in HIV-infected patients.

OBJECTIVE: To update the 2010 recommendations on the evaluation and management of renal disease in HIV-infected patients. METHODS: This document was approved by a panel of experts from the AIDS Working Group (GESIDA) of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), the Spanish Society of Nephrology (S.E.N.), and the Spanish Society of Clinical Chemistry and Molecular Pathology (SEQC). The quality of evidence and the level of recommendation were evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. RESULTS: The basic renal work-up should include measurements of serum creatinine, estimated glomerular filtration rate by CKD-EPI, Urine protein-to-creatinine ratio, and urinary sediment. Tubular function tests should include determination of serum phosphate levels and urine dipstick for glucosuria. In the absence of abnormal values, renal screening should be performed annually. In patients treated with tenofovir or with risk factors for chronic kidney disease (CKD), more frequent renal screening is recommended. In order to prevent disease progression, potentially nephrotoxic antiretroviral drugs are not recommended in patients with CKD or risk factors for CKD. The document advises on the optimal time for referral of a patient to the nephrologist and provides indications for renal biopsy. The indications for and evaluation and management of dialysis and renal transplantation are also addressed. CONCLUSIONS: Renal function should be monitored in all HIV-infected patients. The information provided in this document should enable clinicians to optimize the evaluation and management of HIV-infected patients with renal disease.

Overall and cause-specific mortality in HIV-positive subjects compared to the general population.

INTRODUCTION: Emerging non-AIDS related causes of death have been observed in HIV-positive subjects in industrialized countries. We aimed to analyze overall and cause-specific excess of mortality of HIV-positive patients compared to the general population and to assess the effect of prognostic factors. MATERIAL AND METHODS: We used generalized linear models with Poisson error structure to estimate overall and cause-specific excess of mortality in HIV-positive patients from 2004 to 2012 in the cohort of the Spanish Network of HIV Research (CoRIS), compared to Spanish general population and to assess the impact of multiple risk factors. We investigated differences between short-term and long-term risk factors effects on excess of mortality. Multiple Imputation by Chained Equations was used to deal with missing data. RESULTS: In 9162 patients there were 363 deaths, 16.0% were non-AIDS malignancies, 10.5% liver and 0.3% cardiovascular related. Excess mortality was 1.20 deaths per 100 person years (py) for all-cause mortality, 0.16 for liver, 0.10 for non-AIDS malignancies and 0.03 for cardiovascular. Short-term (first-year follow-up) excess Hazard Ratio (eHR) for global mortality for baseline AIDS was 4.27 (95% CI 3.06-6.01) and 1.47 (95% CI 0.95-2.27) for HCV coinfection; long-term (subsequent follow-up) eHR for baseline AIDS was 0.88 (95% CI 0.58-1.35) and 4.48 (95% CI 2.71-7.42) for HCV coinfection. Lower CD4 count and higher viral load at entry, lower education, being male and over 50 years were predictors for overall excess mortality. Excess of liver mortality was higher in patients with CD4 counts at entry below 200 cells compared to those above 350 (eHR: 6.49, 95% CI 1.21-34.84) and in HCV-coinfected patients (eHR: 3.85, 95% CI 0.85- 17.37), although it was borderline significant. Patients over 50 years old (eHR: 5.55, 95%CI 2.4-12.85) and HCV coinfected (eHR: 5.81, 95% CI 2.6-13) showed a higher risk of non-AIDS malignancies mortality excess. Excess of cardiovascular mortality was related with HCV coinfection (eHR: 6.68, 95% CI 1.25-35.73). CONCLUSIONS: Our results show overall, liver, non-AIDS malignancies and cardiovascular excess of mortality associated with being HIV-positive, despite improvements in HIV disease management and antiretroviral therapies. Differential short-term and long-term effect of AIDS before entry and HCV coinfection was found for overall mortality.

Telaprevir or boceprevir in HIV/HCV-1 co-infected patients in a real-life setting. Interim analysis (24 weeks). COINFECOVA-SEICV study.

INTRODUCTION: In general, HIV co-infected patients included in clinical trials evaluating the hepatitis C virus (HCV) therapy with telaprevir (TVR) or boceprevir (BOC) with advanced fibrosis, are scarce. We analyze data concerning the use of these drugs in a real-life clinical setting with patients affected by a more advanced degree of fibrosis in a Spanish cohort. METHODS: We evaluated safety and efficacy in an interim analysis encompassing the first 24 weeks of triple therapy with peginterferon (alfa-2a or alfa-2b), ribavirin and TVR or BOC in an observational, multicentre study. HIV/HCV genotype 1 co-infected patients beginning therapy from January 2012 to July 2013 were included. RESULTS: Enrolled patients were 155 (144 patients on TVR and 11 on BOC), average age was 47 years, 83% were male. With respect to HCV treatment, 44% were naïve, 13% relapsers, 17% partial responders, 21% null responders, and in seven patients, the previous response was unknown. All but three (98%) were under antiretroviral therapy (ART) (other than reverse transcriptase inhibitors, the backbone was raltegravir 43%, atazanavir 35%, and etravirine 28%). Median HCV-RNA at baseline was 6.1 log10, 54% were cirrhotic and 38% F3. At week 4, 93% of patients continued on therapy, 81% at w12, and 73% at w24. Virological failure was observed more frequently in: cirrhotic patients (19% [95% CI, 11-27]) vs F3 (12% [CI, 4-20]); patients with TT allele of the IL28B polymorphism (40% [CI, 18-61]) vs CT (21% [CI, 12-31]), or CC (2,2% [CI, -2-6]); previous null responders (37.5% [CI, 21-54]) vs partial responders (15.4% [CI, 1-29]), naïve (13% [CI, 5-21]) or relapsers (0% [CI, 0-0]); and in patients with a genotype subtype 1a (23.6% [CI, 57-76]) vs 1b (8.1% [CI, -1-17]). Overall, 17% had virological failure and in 8% treatment was discontinued due to adverse events. Severe adverse events occurred in 30 patients (19%). Haematologic disorders were the most common type including severe anaemia in 12 (7.7%) patients. Erythropoietin was employed in 41 patients (26.4%) and 11 (7.1%) received blood transfusions. Nineteen patients (12.2%) were treated with G-CSF, and 17 (11%) with thrombopoietin-receptor agonists. Five patients died (3.2%), three due to hepatic decompensation, one due to pneumonia and one due to pulmonary hypertension. CONCLUSIONS: In a real-life setting, therapy against HCV in co-infected patients with advanced liver fibrosis shows high virologic success at 24 weeks. However, frequent haematologic disorders are observed and a close monitoring and an intensive therapy are needed to optimize the results.

[Executive summary of the recommendations on the evaluation and management of renal disease in human immunodeficiency virus-infected patients]. / Resumen ejecutivo del documento de consenso sobre el manejo de la patología renal en pacientes con infección por el virus de la inmunodeficiencia humana.

The aim of this article is to update the 2010 recommendations on the evaluation and management of renal disease in human immunodeficiency virus (HIV)-infected patients. Renal function should be monitored in all HIV-infected patients. The basic renal work-up should include measurements of serum creatinine, estimated glomerular filtration rate by CKD-EPI, urine protein-to-creatinine ratio, and urinary sediment. Tubular function tests should include determination of serum phosphate levels and urine dipstick for glycosuria. In the absence of abnormal values, renal screening should be performed annually. In patients treated with tenofovir, or with risk factors for chronic kidney disease (CKD), more frequent renal screening is recommended. In order to prevent disease progression, potentially nephrotoxic antiretroviral drugs are not recommended in patients with CKD or risk factors for CKD. The document provides indications for renal biopsy and advises on the optimal time for referral of a patient to the nephrologist. The indications for and evaluation and management of dialysis and renal transplantation are also addressed.

Effects of sustained viral response in patients with HIV and chronic hepatitis C and nonadvanced liver fibrosis.

OBJECTIVE: We assessed the effects of sustained viral response (SVR), after treating with interferon-ribavirin (IF-RB), on mortality, liver-related (LR) events (decompensation, hepatocellular carcinoma), HIV progression, and liver stiffness in HIV/hepatitis C virus (HCV)-coinfected patients with nonadvanced liver fibrosis. METHODS: From a cohort of HIV/HCV-coinfected patients treated with IF-RB, we selected those with baseline liver fibrosis stages F0, F1, or F2 according to METAVIR. The study started when IF-RB was stopped and ended at death or at the last follow-up visit. RESULTS: A total of 695 patients were included (HCV genotype 1 or 4, 431; F0, 77; F1, 290; and F2, 328), and 274 patients achieved SVR. After a median follow-up of 4.9 years, the adjusted hazard ratio (aHR) [95% confidence interval (CI)] of LR events or overall death, for patients with SVR taking the group of patients with no SVR as a reference was 0.217 (0.079 to 0.599) (P = 0.003) for the whole cohort with F0 to F2. For patients with F0, the aHR (95% CI) was 0.514 (0.040 to 6.593) (P = 0.609), for patients with F1, the aHR (95% CI) was 0.305 (0.053 to 1.762) (P = 0.185), and for patients with F2, it was 0.075 (0.009 to 0.662) (P = 0.020). We also found that, in comparison with no SVR, SVR was followed by less frequent HIV progression for the entire population (F0 to F2) and less frequent liver stiffness across all categories of fibrosis. CONCLUSIONS: SVR in HIV/HCV-coinfected patients with moderate stages of liver fibrosis is associated with a reduction of mortality and LR events, and with a reduction of progression of HIV and liver fibrosis.

Executive summary of the GeSIDA/National AIDS Plan consensus document on antiretroviral therapy in adults infected by the human immunodeficiency virus (updated January 2014).

In this update, antiretroviral therapy (ART) is recommended for all patients infected by type 1 human immunodeficiency virus (HIV-1). The strength and grade of the recommendation varies with clinical circumstances, number of CD4 cells, comorbid conditions and prevention of transmission of HIV. The objective of ART is to achieve an undetectable plasma viral load. Initial ART should always comprise a combination of 3 drugs, including 2 nucleoside reverse transcriptase inhibitors and a third drug from a different family (non-nucleoside reverse transcriptase inhibitor, protease inhibitor, or integrase inhibitor). This update presents the causes and criteria for switching ART in patients with undetectable plasma viral load and in cases of virological failure. An update is also provided for the specific criteria for ART in special situations (acute infection, HIV-2 infection, and pregnancy) and with comorbid conditions (tuberculosis or other opportunistic infections, kidney disease, liver disease, and cancer).
