Intravitreal ranibizumab in the treatment of choroidal neovascularization associated with idiopathic central serous chorioretinopathy.

PURPOSE: We evaluate the functional and anatomic outcome after intravitreal ranibizumab treatment in patients with choroidal neovascularization (CNV) related to chronic central serous chorioretinopathy (CSC). METHODS: This is a small case series of 5 eyes with CNV associated with chronic CSC treated with intravitreal injection of 0.5 mg ranibizumab in the Jules Gonin University Eye Hospital from July 2007 to July 2009. Baseline and monthly follow-up visits included best-corrected visual acuity (BCVA), fundus examination, and optical coherence tomography (OCT). Fluorescein and indocyanine green angiography (ICG) were performed at baseline and repeated at least every 6 months. RESULTS: We studied 5 eyes of 4 patients with a mean age of 66 years. Mean follow-up was 21 months (SD 1.9). The mean number of intravitreal injections administered for each patient was 10 (SD 4.6). The mean initial BCVA was 0.23 (decimal equivalent) (logMAR 0.64, SD 0.13). At the last follow-up, mean BCVA was 0.44 decimal equivalent (logMAR 0.36, SD 0.31). Mean central macular thickness (CMT) measured with OCT was 330 microm (SD 43) at baseline and decreased at the final follow-up to 243 microm (SD 44 ). Persistent intraretinal or subretinal fluid on OCT and/or multifocal areas of increased choroidal permeability on ICG angiographies were present in all patients at the last follow-up visit. CONCLUSIONS: Intravitreal ranibizumab appeared to be an effective treatment of CNV related to chronic CSC. However, residual intraretinal or subretinal fluid and increased choroidal permeability persisted. Prospective controlled studies are warranted to evaluate the long-term safety and efficacy of intravitreal ranibizumab.

Absence of BK viremia clearance after low-dose cidofovir therapy in kidney transplant recipients with BK virus associated nephropathy

Background: BK virus associated nephropathy occurs in 1-10% of kidney transplant recipients and may be a cause of graft loss. This infection is difficult to manage because of the absence of specific therapy. Cidofovir, a DNA polymerase inhibitor approved for the treatment of CMV retinitis, has shown in vitro activity against BK virus and some clinical efficacy when used at low-dose in uncontrolled series. Objective: To assess the efficacy of low-dose Cidofovir in the treatment of BK virus associated nephropathy. Method: Two adult kidney transplant recipients with biopsy-proven BK nephropathy and persistent high viremia (>10,000 copies/ml) despite 3-month reduction of immunosuppressive therapy were treated by Cidofovir 0.5 mg/kg fortnightly for a total of 16 weeks (8 doses). Clinical response was assessed by following BK viremia. Results: No decrease in BK viremia was observed at any point during cidofovir therapy (see figure). Creatinine clearance remained stable during therapy and no side-effects of Cidofovir were observed. Conclusions: Low-dose Cidofovir therapy was not associated with a clearance or with a significant decrease of BK viremia. This pilot study does not confirm previous reports suggesting clinical efficacy of Cidofovir for BK virus associated nephropathy.

Mechanism of reduction of virus release and cell-cell fusion in persistent canine distemper virus infection.

Canine distemper virus (CDV), a mobillivirus related to measles virus causes a chronic progressive demyelinating disease, associated with persistence of the virus in the central nervous system (CNS). CNS persistence of morbilliviruses has been associated with cell-to-cell spread, thereby limiting immune detection. The mechanism of cell-to-cell spread remains uncertain. In the present study we studied viral spread comparing a cytolytic (non-persistent) and a persistent CDV strain in cell cultures. Cytolytic CDV spread in a compact concentric manner with extensive cell fusion and destruction of the monolayer. Persistent CDV exhibited a heterogeneous cell-to-cell pattern of spread without cell fusion and 100-fold reduction of infectious viral titers in supernatants as compared to the cytolytic strain. Ultrastructurally, low infectious titers correlated with limited budding of persistent CDV as compared to the cytolytic strain, which shed large numbers of viral particles. The pattern of heterogeneous cell-to-cell viral spread can be explained by low production of infectious viral particles in only few areas of the cell membrane. In this way persistent CDV only spreads to a small proportion of the cells surrounding an infected one. Our studies suggest that both cell-to-cell spread and limited production of infectious virus are related to reduced expression of fusogenic complexes in the cell membrane. Such complexes consist of a synergistic configuration of the attachment (H) and fusion (F) proteins on the cell surface. F und H proteins exhibited a marked degree of colocalization in cytolytic CDV infection but not in persistent CDV as seen by confocal laser microscopy. In addition, analysis of CDV F protein expression using vaccinia constructs of both strains revealed an additional large fraction of uncleaved fusion protein in the persistent strain. This suggests that the paucity of active fusion complexes is due to restricted intracellular processing of the viral fusion protein.

Isolated limb perfusion with tumor necrosis factor and melphalan for non-resectable soft tissue sarcomas: long-term results on efficacy and limb salvage in a selected group of patients

Background And Objectives: Isolated limb perfusion with TNF-alpha and melphalan (TM-ILP) is a limb salvage therapy for non-resectable soft tissue sarcomas (STS) of the extremities. It is indicated for patients for whom amputation or debilitating surgery is the only alternative. It can be used either as an exclusive therapy (in palliation) or as a neo-adjuvant treatment, followed by marginal resection of tumor remnants with minimal functional impairment. Methods: Between February 1992 and March 2006, 57 TM-ILPs were performed on 51 patients with 88% high grade and 84% advanced stage tumors. Results: Mean follow-up is 38.9 months (4-159, median 22 months). Twenty-one percent patients had significant early complications, with 3 major re-operations, and 23% suffered long-lasting complications. Complete response was observed in 25%, partial response in 42%, stable disease in 14% and progressive disease in 14%. Resection of the tumor remnants was possible in 65%. A complementary treatment was necessary in 31%, mostly radiation therapy. A local recurrence was observed in 35%, after a mean of 20.3 months (2-78), and distant relapse was seen in 45%, after a mean of 13.4 months (5-196). Mean Disease-free survival was 14.9 months, and overall 5-year-survival 43.5%. Amputation rate at 5 years was 24%. Conclusions: TM-ILP is a conservative treatment with a high complications rate, but it can be successful even for the most severe STS of extremities. As a consequence the limb can be spared from amputation or debilitating surgery on the long term in about 75% of patients

Efficacy Of An Explicit Handwriting Program

The aim of this study was to investigate the effects of an explicit handwriting program introduced during the first grade of elementary school. Grade 1 children (N=23) with an age range of 6.1 to 7.4 yr. (15 girls, 8 boys) were administered an additional handwriting program of two weekly sessions of 45 min. over six weeks. Another group of 19 Grade 1 children (11 girls, 8 boys) received only the regular handwriting program of one weekly session. The Concise Assessment Scale for Children's Handwriting was administered to measure the changes in quality and speed of handwriting. The children given the explicit program showed better quality and speed of handwriting than did the control group. Their handwriting was more regular, with fewer ambiguous letters and fewer incorrect relative heights.

Persistent palinopsia following ingestion of lysergic acid diethylamide (LSD).

OBJECTIVE: To identify a distinctive chronic visual complication of lysergic acid diethylamide (LSD) use. DESIGN: Description of the clinical findings in three patients with this disorder. SETTING: A neuro-ophthalmology referral center. RESULTS: All three patients experienced prolonged afterimages (palinopsia) during LSD intoxication and have continued to be symptomatic up to 3 years after they ceased to ingest the drug. Results of neuro-ophthalmologic and neurologic examinations and neuroimaging and electrophysiologic studies were normal. CONCLUSIONS: We have described three patients in whom persistent palinopsia developed following ingestion of LSD. Clinicians should inquire about past LSD use in all patients who initially have seemingly spontaneous, isolated palinopsia. Recognition of this distinctive clinical syndrome associated with LSD use might avoid unnecessary anxiety and excessive diagnostic tests for patients with this disorder.

Dégénérescence maculaire liée à l'âge exsudative: efficacité et limites des différents traitements [Exudative age-related macular degeneration: efficacy and limits of the different treatments].

Ocular neovascularizations are responsible for irreversible loss of vision in various diseases, including age-related macular degeneration. Treatments have changed greatly, and photodynamic therapy with verteporfin has come into common use. However, the visual prognosis remains poor. The recent approval of new antiangiogenic molecules such as ranibizumab and pegaptanib should allow for new therapeutical possibilities. The unapproved ophthalmological use of bevacizumab requires further studies. This paper updates what is known about old and new neovascularization treatments: their mechanism of action, their efficacy, and their toxicity. It reviews the principal clinical studies, and concludes with the recognized recommendations. For the first time, ophthalmologists can hope not only to stabilize loss of vision, but also to improve visual acuity. Complementary treatments can now be tested in associations, concomitantly or not, with the hope of improving visual results.

Efficacy, tolerability and risk factors for virological failure of darunavir-based therapy for treatment-experienced HIV-infected patients: the Swiss HIV Cohort Study.

OBJECTIVES: Darunavir was designed for activity against HIV resistant to other protease inhibitors (PIs). We assessed the efficacy, tolerability and risk factors for virological failure of darunavir for treatment-experienced patients seen in clinical practice. METHODS: We included all patients in the Swiss HIV Cohort Study starting darunavir after recording a viral load above 1000 HIV-1 RNA copies/mL given prior exposure to both PIs and nonnucleoside reverse transcriptase inhibitors. We followed these patients for up to 72 weeks, assessed virological failure using different loss of virological response algorithms and evaluated risk factors for virological failure using a Bayesian method to fit discrete Cox proportional hazard models. RESULTS: Among 130 treatment-experienced patients starting darunavir, the median age was 47 years, the median duration of HIV infection was 16 years, and 82% received mono or dual antiretroviral therapy before starting highly active antiretroviral therapy. During a median patient follow-up period of 45 weeks, 17% of patients stopped taking darunavir after a median exposure of 20 weeks. In patients followed beyond 48 weeks, the rate of virological failure at 48 weeks was at most 20%. Virological failure was more likely where patients had previously failed on both amprenavir and saquinavir and as the number of previously failed PI regimens increased. CONCLUSIONS: As a component of therapy for treatment-experienced patients, darunavir can achieve a similar efficacy and tolerability in clinical practice to that seen in clinical trials. Clinicians should consider whether a patient has failed on both amprenavir and saquinavir and the number of failed PI regimens before prescribing darunavir.

Influenza vaccination in immunocompromised patients: efficacy and safety.

Yearly administration of the influenza vaccine is the main strategy to prevent influenza in immunocompromised patients. Here, we reviewed the recent literature regarding the clinical significance of the influenza virus infection, as well as the immunogenicity and safety of the influenza vaccine in HIV‑infected individuals, solid-organ and stem-cell transplant recipients and patients receiving biological agents. Epidemiological data produced during the 2009 influenza pandemic have confirmed that immunocompromised patients remain at high risk of influenza-associated complications, namely viral and bacterial pneumonia, hospitalization and even death. The immunogenicity of the influenza vaccine is overall reduced in immunocompromised patients, although a significant clinical protection from influenza is expected to be obtained with vaccination. Influenza vaccination is safe in immunocompromised patients. The efficacy of novel strategies to improve the immunogenicity to the vaccine, such as the use of adjuvanted vaccines, boosting doses and intradermal vaccination, needs to be validated in appropriately powered clinical trials.

Safety and efficacy of the peptide-based therapeutic vaccine for HIV-1, Vacc-4x: a phase 2 randomised, double-blind, placebo-controlled trial.

BACKGROUND: Present combination antiretroviral therapy (cART) alone does not cure HIV infection and requires lifelong drug treatment. The potential role of HIV therapeutic vaccines as part of an HIV cure is under consideration. Our aim was to assess the efficacy, safety, and immunogenicity of Vacc-4x, a peptide-based HIV-1 therapeutic vaccine targeting conserved domains on p24(Gag), in adults infected with HIV-1. METHODS: Between July, 2008, and June, 2010, we did a multinational double-blind, randomised, phase 2 study comparing Vacc-4x with placebo. Participants were adults infected with HIV-1 who were aged 18-55 years and virologically suppressed on cART (viral load <50 copies per mL) with CD4 cell counts of 400 × 10(6) cells per L or greater. The trial was done at 18 sites in Germany, Italy, Spain, the UK, and the USA. Participants were randomly assigned (2:1) to Vacc-4x or placebo. Group allocation was masked from participants and investigators. Four primary immunisations, weekly for 4 weeks, containing Vacc-4x (or placebo) were given intradermally after administration of adjuvant. Booster immunisations were given at weeks 16 and 18. At week 28, cART was interrupted for up to 24 weeks. The coprimary endpoints were cART resumption and changes in CD4 counts during treatment interruption. Analyses were by modified intention to treat: all participants who received one intervention. Furthermore, safety, viral load, and immunogenicity (as measured by ELISPOT and proliferation assays) were assessed. The 52 week follow-up period was completed in June, 2011. For the coprimary endpoints the proportion of participants who met the criteria for cART resumption was analysed with a logistic regression model with the treatment effect being assessed in a model including country as a covariate. This study is registered with ClinicalTrials.gov, number NCT00659789. FINDINGS: 174 individuals were screened; because of slow recruitment, enrolment stopped with 136 of a planned 345 participants and 93 were randomly assigned to receive Vacc-4x and 43 to receive placebo. There were no differences between the two groups for the primary efficacy endpoints in those participants who stopped cART at week 28. Of the participants who resumed cART, 30 (34%) were in the Vacc-4x group and 11 (29%) in the placebo group, and percentage changes in CD4 counts were not significant (mean treatment difference -5·71, 95% CI -13·01 to 1·59). However, a significant difference in viral load was noted for the Vacc-4x group both at week 48 (median 23 100 copies per mL Vacc-4x vs 71 800 copies per mL placebo; p=0·025) and week 52 (median 19 550 copies per mL vs 51 000 copies per mL; p=0·041). One serious adverse event, exacerbation of multiple sclerosis, was reported as possibly related to study treatment. Vacc-4x was immunogenic, inducing proliferative responses in both CD4 and CD8 T-cell populations. INTERPRETATION: The proportion of participants resuming cART before end of study and change in CD4 counts during the treatment interruption showed no benefit of vaccination. Vacc-4x was safe, well tolerated, immunogenic, seemed to contribute to a viral-load setpoint reduction after cART interruption, and might be worth consideration in future HIV-cure investigative strategies.

Morphological Study of Intracardiac Signals as a New Tool to Track the Efficiency of Stepwise Ablation of Persistent Atrial Fibrillation

Intracardiac organization indices such as atrial fibrillation (AF) cycle length (AFCL) have been used to track the efficiency of stepwise catheter ablation (step-CA) of longstanding persistent AF, however with limited success. The morphology of AF activation waves reflects the underlying activation patterns. Its temporal evolution is a local organization indicator that could be potentially used for tracking the efficiency of step-CA. We report a new method for characterizing the structure of the temporal evolution of activation wave morphology. Using recurrence plots, novel organization indices are proposed. By computing their relative evolution during the first step of ablation vs baseline, we found that these new parameters are superior to AFCL to track the effect of step-CA "en route" to AF termination.

Persistent infection of arenaviruses : molecular mechanisms and pathogenesis

Arenaviruses are enveloped negative single strand RNA viruses that include a number of important human pathogens. The most prevalent human pathogen among the arenaviruses is the Old World arenavirus Lassa virus (LASV) which is endemic in West Africa from Senegal to Cameroon. LASV is the etiologic agent of a severe viral hemorrhagic fever named Lassa fever whose mortality rate can reach 30% in hospitalized patients. One of the hallmarks of fatal arenavirus infection in humans is the absence of an effective innate and adaptive immune response. In nature, arenaviruses are carried by rodents which represent the natural reservoirs as well as the vectors for transmission. In their natural rodent reservoir, arenaviruses have the ability to establish persistent infection without any overt signs and symptoms of pathology. We believe that the modulation of the host cell's innate immunity by arenaviruses is a key determinant for persistence in the natural host and for the pathogenesis in man. In this thesis, we studied the interaction of arenaviruses with two main branches of the host's innate anti-viral defense, the type I interferon (IFN) system and virus-induced mitochondrial apoptosis. The arenavirus nucleoprotein (NP) is responsible for the anti-IFN activity of arenaviruses. Specifically, NP blocks the activation and the nuclear translocation of the transcription factor interferon regulatory factor 3 (IRF3) which leads to type I IFN production. LASV and the prototypic arenavirus lymphocytic choriomeningitis virus (LCMV) NPs contain a 3'-5'exoribonuclease domain in the C terminal part that has been linked to the anti-IFN activity of NP. In the first project, we sought to identify cellular component(s) of the type I IFN induction pathway targeted by the viral NP. Our study revealed that LCMV NP prevents the activation of IRF3 by blocking phosphorylation of the transcription factor. We found that LCMV NP specifically targets the IRF-activating kinase IKKs, and this specific binding is conserved within the Arenaviridae. We could also demonstrate that LCMV NP associates with the kinase domain of IKKs involving NP's C-terminal region. Lastly, we showed that the binding of LCMV NP inhibits the kinase activity of IKKs. This study allowed the discovery of a new cellular interacting partner of arenavirus NP. This newly described association may play a role in the anti-IFN activity of arenaviruses but potentially also in other aspects of arenavirus infection. For the second project, we investigated the ability of arenaviruses to avoid and/or suppress mitochondrial apoptosis. As persistent viruses, arenaviruses evolved a "hit and stay" survival strategy where the apoptosis of the host cell would be deleterious. We found that LCMV does not induce mitochondrial apoptosis at any time during infection. Specifically, no caspase activity, no cytochrome c release from the mitochondria as well as no cleavage of poly (ADP-ribose) polymerase (PARP) were detected during LCMV infection. Interestingly, we found that virus-induced mitochondrial apoptosis remains fully functional in LCMV infected cells, while the induction of type IIFN is blocked. Since both type IIFN production and virus- induced mitochondrial apoptosis critically depend on the pattern recognition receptor (PRR) RIG-I, we examined the role of RIG-I in apoptosis in LCMV infected cells. Notably, virus- induced mitochondrial apoptosis in LCMV infected cells was found to be independent of RIG- I and MDA5, but still depended on MAVS. Our study uncovered a novel mechanism by which arenaviruses alter the host cell's pro-apoptotic signaling pathway. This might represent a strategy arenaviruses developed to maintain this branch of the innate anti-viral defense in absence of type I IFN response. Taken together, these results allow a better understanding of the interaction of arenaviruses with the host cell's innate immunity, contributing to our knowledge about pathogenic properties of these important viruses. A better comprehension of arenavirus virulence may open new avenues for vaccine development and may suggest new antiviral targets for therapeutic intervention against arenavirus infections. - Les arenavirus sont des virus enveloppés à ARN simple brin qui comportent un grand nombre de pathogènes humains. Le pathogène humain le plus important parmi les arenavirus est le virus de Lassa qui est endémique en Afrique de l'Ouest, du Sénégal au Cameroun. Le virus de Lassa est l'agent étiologique d'une fièvre hémorragique sévère appelée fièvre de Lassa, et dont le taux de mortalité peut atteindre 30% chez les patients hospitalisés. L'une des caractéristiques principales des infections fatales à arenavirus chez l'Homme est l'absence de réponse immunitaire innée et adaptative. Dans la nature, les arenavirus sont hébergés par différentes espèces de rongeur, qui représentent à la fois les réservoirs naturels et les vecteurs de transmission des arenavirus. Dans leur hôte naturel, les arenavirus ont la capacité d'établir une infection persistante sans symptôme manifeste d'une quelconque pathologie. Nous pensons que la modulation de système immunitaire inné de la cellule hôte par les arenavirus est un paramètre clé pour la persistance au sein de l'hôte naturel, ainsi que pour la pathogenèse chez l'Homme. L'objectif de cette thèse était d'étudier l'interaction des arenavirus avec deux branches essentielles de la défense antivirale innée de la cellule hôte, le système interféron (IFN) de type I et l'apoptose. La nucléoprotéine virale (NP) est responsable de l'activité anti-IFN des arenavirus. Plus spécifiquement, la NP bloque 1'activation et la translocation nucléaire du facteur de transcription IRF3 qui conduit à la production des IFNs de type I. La NP du virus de Lassa et celle du virus de la chorioméningite lymphocytaire (LCMV), l'arénavirus prototypique, possèdent dans leur extrémité C-terminale un domaine 3'-5' exoribonucléase qui a été associé à l'activité anti-IFN de ces protéines. Dans un premier projet, nous avons cherché à identifier des composants cellulaires de la cascade de signalisation induisant la production d'IFNs de type I qui pourraient être ciblés par la NP virale. Nos recherches ont révélé que la NP de LCMV empêche 1'activation d'IRF3 en bloquant la phosphorylation du facteur de transcription. Nous avons découvert que la NP de LCMV cible spécifiquement la kinase IKKe, et que cette interaction spécifique est conservée à travers la famille des Arenaviridae. Notre étude a aussi permis de démontrer que la NP de LCMV interagit avec le domaine kinase d'IKKe et que l'extrémité C-terminale de la NP est impliquée. Pour finir, nous avons pu établir que l'association avec la NP de LCMV inhibe l'activité kinase d'IKKe. Cette première étude présente la découverte d'un nouveau facteur cellulaire d'interaction avec la NP des arenavirus. Cette association pourrait jouer un rôle dans l'activité anti-IFN des arénavirus, mais aussi potentiellement dans d'autres aspects des infections à arénavirus. Pour le second projet, nous nous sommes intéressés à la capacité des arénavirus à éviter et/ou supprimer l'apoptose mitochondriale. En tant que virus persistants, les arénavirus ont évolué vers une stratégie de survie "hit and stay" pour laquelle l'apoptose de la cellule hôte serait néfaste. Nous avons observé qu'à aucun moment durant l'infection LCMV n'induit l'apoptose mitochondriale. Spécifiquement, aucune activité de caspase, aucune libération mitochondriale de cytochrome c ainsi qu'aucun clivage de la polymerase poly(ADP-ribose) (PARP) n'a été détecté pendant l'infection à LCMV. Il est intéressant de noter que l'apoptose mitochondriale induite par les virus reste parfaitement fonctionnelle dans les cellules infectées par LCMV, alors que l'induction de la réponse IFN de type I est bloquée dans les mêmes cellules. La production des IFNs de type I et l'apoptose mitochondriale induite par les virus dépendent toutes deux du récepteur de reconnaissance de motifs moléculaires RIG-I. Nous avons, par conséquent, investigué le rôle de RIG-I dans l'apoptose qui a lieu dans les cellules infectées par LCMV lorsqu'on les surinfecte avec un autre virus pro-apoptotique. En particulier, l'apoptose mitochondriale induite par les surinfections s'est révélée indépendante de RIG-I et MDA5, mais dépendante de MAVS dans les cellules précédemment infectées par LCMV. Notre étude démontre ainsi l'existence d'un nouveau mécanisme par lequel les arénavirus altèrent la cascade de signalisation pro-apoptotique de la cellule hôte. Il est possible que les arénavirus aient développé une stratégie permettant de maintenir fonctionnelle cette branche de la défense antivirale innée en l'absence de réponse IFN de type I. En conclusion, ces résultats nous amènent à mieux comprendre l'interaction des arénavirus avec l'immunité innée de la cellule hôte, ce qui contribue aussi à améliorer notre connaissance des propriétés pathogéniques de ces virus. Une meilleure compréhension des facteurs de virulence des arénavirus permet, d'une part, le développement de vaccins et peut, d'autre part, servir de base pour la découverte de nouvelles cibles thérapeutiques utilisées dans le traitement des infections à arénavirus.

Application in the STRATHE trial of a score system to compare the efficacy and the tolerability of different therapeutic strategies in the management of hypertension

A score system integrating the evolution of efficacy and tolerability over time was applied to a subpopulation of the STRATHE trial, a trial performed according to a parallel group design, with a double-blind, random allocation to either a fixed-dose combination strategy (perindopril/indapamide 2 mg/0.625 mg, with the possibility to increase the dose to 3 mg/0.935 mg, and 4 mg/1.250 mg if needed, n = 118), a sequential monotherapy approach (atenolol 50 mg, followed by losartan 50 mg and amlodipine 5 mg if needed, n = 108), or a stepped-care strategy (valsartan 40 mg, followed by valsartan 80 mg and valsartan 80 mg+ hydrochlorothiazide 12.5 mg if needed, n = 103). The aim was to lower blood pressure below 140/90 mmHg within a 9-month period. The treatment could be adjusted after 3 and 6 months. Only patients in whom the study protocol was strictly applied were included in this analysis. At completion of the trial the total score averaged 13.1 +/- 70.5 (mean +/- SD) using the fixed-dose combination strategy, compared with -7.2 +/- 81.0 using the sequential monotherapy approach and -17.5 +/- 76.4 using the stepped-care strategy. In conclusion, the use of a score system allows the comparison of antihypertensive therapeutic strategies, taking into account at the same time efficacy and tolerability. In the STRATHE trial the best results were observed with the fixed-dose combination containing low doses of an angiotensin enzyme converting inhibitor (perindopril) and a diuretic (indapamide).
