RESUMO

OBJECTIVES: To study the association between CD4/CD8 ratio and morbidity in HIV-infected patients on antiretroviral therapy (ART). METHODS: The APROCO/COPILOTE cohort enrolled patients initiating a protease inhibitor-containing ART in 1997-1999. The association between occurrence of first non AIDS-defining severe events (NADE) and time-dependent measures of immune restoration was assessed by 4 Cox models with different definitions of restoration, CD4+ cell counts (CD4), CD4/CD8 ratio, both CD4 and CD4/CD8 ratio, or a composite variable (CD4< 500/mm3, CD4 > 500/mm3 and CD4/CD8 ratio < 1, CD4 > 500/mm3 and CD4/CD8 ratio > 1). Models adjusted on baseline characteristics and time-dependent viral load were compared using Akaike Information Criterion. RESULTS: We included 1227 patients. Median duration of follow-up was 9.2 years (IQR: 4.2-11.4). Median CD4 was 530/mm3 at 9 years. Median CD4/CD8 ratio was 0.3 (IQR: 0.2-0.5) at baseline and 0.6 (IQR: 0.4-0.9) after 9 years. Incidence of first NADE was 7.4/100 person-years, the most common being bacterial infections (21%), cardiovascular events (14%) and cancers (10%). For both bacterial infections and cardiovascular events, the CD4/CD8 ratio did not add predictive information to the CD4 cell count. However, low CD4/CD8 ratio was the best predictor of non-AIDS cancers (adjusted HR = 2.13 for CD4/CD8 < 0.5; 95% CI = 1.32-3.44). CONCLUSIONS: CD4/CD8 ratio remains < 1 in most HIV-infected patients despite long-term CD4+ cell counts restoration on ART. A CD4/CD8 ratio < 0.5 could identify patients who require a more intensive strategy of cancer prevention or screening.

RESUMO

BACKGROUND: Although the role of clinical/biological factors associated with mortality has already been explored in HIV-infected patients on antiretroviral therapy (ART), to date little attention has been given to the potential role of social vulnerability. This study aimed to construct an appropriate measure of social vulnerability and to evaluate whether this measure is predictive of increased mortality risk in ART-treated patients followed up in the ANRS CO8 APROCO-COPILOTE cohort. METHODS: The cohort enrolled 1,281 patients initiating a protease inhibitor-based regimen in 1997-1999. Clinical/laboratory data were collected every 4 months. Self-administered questionnaires collected psycho-social/behavioural characteristics at enrolment (month [M] 0), M4 and every 8-12 months thereafter. A multiple correspondence analysis using education, employment and housing indicators helped construct a composite indicator measuring social vulnerability. The outcome studied was all-cause deaths occurring after M4. The relationship between social vulnerability and mortality, after adjustment for other predictors, was studied using a shared-frailty Cox model, taking into account informative study dropout. RESULTS: Over a median (IQR) follow-up of 7.9 (3.0-11.2) years, 121 deaths occurred among 1,057 eligible patients, corresponding to a mortality rate (95% CI) of 1.64 (1.37, 1.96)/100 person-years. Leading causes of death were non-AIDS defining cancers (n=26), AIDS (n=23) and cardiovascular diseases (n=12). Social vulnerability (HR [95% CI] =1.2 [1.0, 1.5]) was associated with increased mortality risk, after adjustment for other known behavioural and bio-medical predictors. CONCLUSIONS: Social vulnerability remains a major mortality predictor in ART-treated patients. A real need exists for innovative interventions targeting individuals cumulating several sources of social vulnerability, to ensure that social inequalities do not continue to lead to higher mortality.

RESUMO

OBJECTIVES: The objective of this study was to analyse the respective roles of personal factors and HIV infection markers on the systemic immune activation/inflammatory profile of long-term antiretroviral treatment-controlled patients. PATIENTS AND METHODS: A panel of soluble immune activation/inflammatory biomarkers was measured in 352 HIV-infected treatment-controlled patients from the APROCO-COPILOTE cohort, all of whom were started on a PI in 1997-99 and had a final evaluation 11 years later, and in 59 healthy controls. RESULTS: A total of 81.5% of the patients were male, with the following characteristics: median age 49 years; 620 CD4 cells/mm(3); 756 CD8 cells/mm(3); CD4/CD8 ratio 0.81; BMI 23.0 kg/m(2); waist-to-hip ratio 0.95. Markers of inflammation-high-sensitivity (hs) IL-6 (median and IQR) (1.3 pg/L, 0.7-2.6), hs C-reactive protein (CRP) (2.1 mg/L, 0.9-4.5) and D-dimer (252 ng/mL, 177-374)-were elevated compared with healthy controls (P < 0.001) and strongly related to each other, as were markers of immune activation [soluble (s) CD14 (1356 ng/mL, 1027-1818), ß2-microglobulin (2.4 mg/L, 2.0-3.1) and cystatin-C (0.93 mg/L, 0.82-1.1)]. Inflammatory and immune activation markers were also associated with each other. In HIV-infected patients: age was related to D-dimer, ß2-microglobulin and cystatin-C levels; being a smoker was related to increased IL-6 and cystatin-C; and BMI and waist-to-hip ratio were related to CRP. Conversely, markers of HIV infection, current CD4 or CD8 values, CD4 nadir, CD4/CD8 ratio, AIDS stage at initiation of PIs, current viral load and duration of ART were not associated with immune activation/inflammation markers. CONCLUSIONS: In these long-term treatment-controlled HIV-infected patients, all systemic markers of inflammation and immune activation were increased compared with healthy controls. This was related to demographic and behavioural factors, but not to markers of severity of the HIV infection. Intervention to decrease low-grade inflammation must thus prioritize modifiable personal factors.

RESUMO

Our goal was to determine if paraoxonase 1 (PON1) activity relates to the presence of metabolic syndrome (MS) and inflammation in HIV patients treated with highly active antiretroviral therapy (HAART). This was a prospective, multicenter study including 269 patients receiving HAART for at least 1 year and a maximum of 4 years. PON1 and inflammatory markers [C reactive protein (CRP), interleukin-6 (IL-6), serum amyloid A (SAA), and soluble tumor necrosis factor receptors 2 (sTNF-R2)] were compared between patients with or without MS and the association between inflammatory markers and PON1 was assessed by logistic regression analyses. MS was found in 18.2% of the patients. Inflammatory markers, with the exception of sTNF-R2, were significantly higher, while PON1 activity was significantly lower in the presence of metabolic syndrome. PON1 activity was significantly related to apolipoprotein C3, CD4 count, and sTNF-R2. It may be concluded that PON1 appears to be a marker for the metabolic syndrome in HIV-infected subjects. PON1 activity is related to dyslipidemia and the immunological status of the patients but is not fully determined by inflammation.

RESUMO

OBJECTIVE: To investigate the relationship between response to antiretroviral therapy (ART), alcohol use and occurrence of a major coronary or other arterial disease event (CADE) in HIV-infected individuals. DESIGN: A cohort study. A Cox model was used to identify the correlates of a first occurrence of a major CADE. SETTING: The French ANRS CO8 APROCO-COPILOTE cohort was set up in 1997 to study clinical progression and patient-reported outcomes (PRO) after initiating a protease inhibitor-containing ART. Clinical data were retrieved from medical records. Self-administered questionnaires collected data on PRO and behaviours, including alcohol use. PARTICIPANTS: Metabolic data were only available for a subgroup (n=675) of the study group (n=1154). MAIN OUTCOME MEASURES: Major coronary or other arterial disease first event. RESULTS: Over the 11-year follow-up, 49 major CADE were observed, with an incidence rate (95% CI)=0.75(0.57 to 0.99) per 100 person-years. Immunodepression (CD4 cell count <200 cells/mm(3)) was associated with an increased risk of CADE (adjusted HR (95% CI)=2.52(1.15 to 5.48)) after adjustment for female gender (0.25(0.08 to 0.83)), age (1.07(1.04 to 1.10)) and smoking>20 cigarettes/day (4.19(2.17 to 8.11)). Moreover, individuals with moderate alcohol consumption (≤4(3) alcohol units (AU)/day for men(women)) had a lower risk of CADE (0.38(0.20 to 0.71)) than alcohol abstainers, although the risk for those drinking>4(3) AU/day for men(women) was not significantly different from this latter group. These associations remained valid after adjustment for metabolic disorders. No significant association with exposure to any specific antiretroviral was detected. CONCLUSIONS: In the long term, absence of immunodepression and moderate alcohol consumption remain associated with a lower risk of a major CADE. Combined interventions to reduce CADE-risk-related behaviours including adherence counselling for assuring long-term immunological response to ART in HIV-infected individuals are now a clinical and public health priority.

RESUMO

BACKGROUND: Psychiatric disorders are relatively common among HIV-infected patients. However, there are few studies about their potential risk factors. This analysis aimed to measure the incidence of severe psychiatric events (PE) among patients receiving combination antiretroviral therapy (cART) of the French APROCO-COPILOTE (ANRS CO8) cohort, and to identify the medical and socio-behavioural correlates of their first episode of depression, suicide or suicide attempt (D/S/SA). METHODS: APROCO-COPILOTE is a cohort of patients started on a protease inhibitor regimen between 1997 and 1999, with prospective medical standardized records and self-administered questionnaires collecting socio-demographic and socio-behavioural data. This analysis included all 11-year follow-up visits for 1,095 patients having completed baseline self-administered questionnaires. A proportional hazard Cox model was used to identify the correlates of a first D/S/SA event. RESULTS: The overall prevalence of severe PE remained low: 50 patients experienced 67 events (incidence rate [95% CI] =1.04 [0.82, 1.32] per 100 person-years). Depression (n=16), suicides (n=5) and suicide attempts (n=14) were the most frequently diagnosed PE (0.54 [0.39, 0.76] per 100 person-years) among 25 patients. Multivariate results showed that unemployment, unstable housing, detectable viral load and smoking more than 20 cigarettes/day were independently associated with D/S/SA. CONCLUSIONS: Although the incidence of severe PE remained relatively low among the patients of APROCO-COPILOTE cohort, this study's results underline a clinically important problem in HIV-infected patients receiving cART. Furthermore, our findings not only emphasize the importance of comprehensive care, especially for socially vulnerable patients, but may also help future studies designed to assess the effectiveness of interventions in reducing the risk of PE during cART.

RESUMO

BACKGROUND: Preoperative coronary angiography (CA) is recommended in patients with acute aortic valve infective endocarditis (AV-IE) and high cardiovascular risk profile but the level of evidence is low and its potential interest may be counterbalanced by the risk of dislodgement of vegetations and contrast-induced nephropathy. OBJECTIVE: To review the use, indications and complication of preoperative CA in patients with AV-IE. Design Retrospective study. PATIENTS: Consecutive series of 83 patients operated on for AV-IE between January 2002 and March 2007. RESULTS: CA was performed in 36 (43%) patients, all but one as a preoperative test. Significant (>or=70%) lesions were observed in 10 patients and six underwent an associated coronary artery bypass graft. 47 patients were operated on without preoperative CA because of young age in 16 or recent CA in 13. Despite being theoretically indicated in all but one of the 18 remaining patients, CA was not performed because surgery as judged too urgent (eight patients) or valvular lesions were estimated as too important (10 patients). While the 35 patients with preoperative CA tended to be healthier (longer time to surgery and lower rate of urgent surgery), anatomical lesions were not different (rate of severe regurgitation, periannular complications and vegetation size, all p>0.20). No embolic event occurred after CA and preoperative CA was not associated with increased in-hospital mortality (p=0.80) or worsening renal function (p=0.93). CONCLUSION: Preoperative CA can be performed at low risk in selected patients with AV-IE and should be considered before surgery in patients with cardiovascular risk factors. Our results support current guidelines.

RESUMO

OBJECTIVE: To determine risk factor for non-AIDS severe clinical events in HIV-infected patients on long-term combination antiretroviral therapy (cART). METHODS: A validation committee reviewed each severe clinical event that occurred in the APROCO/COPILOTE (ANRS CO8) cohort that enrolled 1281 patients in 1997-1999 at the initiation of cART containing protease inhibitor. Probability of the occurrence of a first non-AIDS, cART-related, and AIDS-defining event was estimated, and potential determinants were studied using Cox regression models. RESULTS: During a median follow-up of 7.3 years, the incidence of non-AIDS events was higher than that of cART-related and AIDS-defining events (10.5, 3.6, and 2.6 per 100 patient-years, respectively). Bacterial (mainly airway) infections were the most frequent non-AIDS events (23.4%) followed by non-AIDS-defining malignancies and cardiovascular events (both 9.5%). Factors independently associated with the occurrence of a first non-AIDS event were age >60 years [hazard ratio (HR) 2.1; 95% confidence interval (CI): 1.3 to 3.2] and CD4 <100 cells per milliliter (HR 2.5; 95% CI: 1.8 to 3.6) but also plasma HIV RNA >4 log10 copies per milliliter at the time of the event (HR 1.9; 95% CI: 1.5 to 2.5). CONCLUSION: Optimization and permanent continuation of long-term antiretroviral therapy in HIV-infected patients is the best strategy to prevent or reduce the occurrence of non-AIDS severe morbidity.

RESUMO

BACKGROUND: To assess the prevalence of and factors associated with tobacco smoking and dependence in HIV patients. METHODS: In a one-day cross-sectional national survey of a representative sample of 82 French units specialized in HIV-infected patient care, 727 consecutive outpatients were asked to complete a self-administered questionnaire, assessing smoking habits, dependence, cessation motivation, other substance abuse, sociocultural characteristics, life with HIV and its treatment. Smoking prevalence and dependence were assessed and compared with a representative sample of the general French population. RESULTS: The questionnaire was completed by 593 (82%) patients: 12% were active or ex-intravenous drug users, 37% were homosexual men, and 43% were active smokers (compared with 31% in the French population) of whom 56% were classified as moderately or highly dependent. Fourteen percent of smokers were highly motivated and free of other substance abuse and of depressive symptoms. Smoking was independently associated with male sex (odds ratio [OR] = 2.38; 95% confidence interval [CI] 0.99-1.11), lower body mass index (OR 1.08; 95% Cl 1.14-1.03), smoking environment (OR 4.75; 95% Cl 3.02-7.49), excessive alcohol consumption (OR 2.50; 95% CI 1.20-5.23), illicit drug use (OR 2.43; 95% CI 1.41-4.19), HIV status disclosure to family (OR 1.81; 95% CI 1.16-2.85) and experience of rejection due to disclosure (OR 1.90; 95% CI 1.14-3.17). Disclosure and drug substitute usage were associated with high tobacco dependence. CONCLUSIONS: Very few HIV smokers seem to be good candidates for a standard tobacco cessation program. Tobacco reduction or cessation strategies should be adapted to this population.

RESUMO

OBJECTIVES: We studied the evolution of the patient-provider relationship (PPR) in HIV-infected patients who reported trustful relationships at highly active antiretroviral therapy (HAART) treatment initiation. METHODS: Psychosocial and clinical data were obtained from the French ANRS CO-8 cohort. Break of trust was defined using the question "How much do you trust the provider who usually treats you at this clinic?" Predictors of a possible break of trust during the 5 years after initiating treatment for those patients reporting a trustful PPR at month 0 were identified using a Cox model. RESULTS: During a total follow-up of 3,044 person-years, 68 (7%) patients reported having at least 1 break of trust in their PPR. Break of trust is independently associated with younger age, dissatisfaction with medical staff's explanations, cigarette smoking, and self-reported side effects and is independently inversely associated with severe HIV-related events and changes of treatment. CONCLUSIONS: A patient's break of trust in his provider is relatively infrequent. Accounting for the influence of immunologic status and psychosocial factors, self-reported side effects are shown to be detrimental to the PPR. Interestingly, clinical events and changes of treatment prevent a possible break of trust by reinforcing the provider's role. These results underline the importance of recognizing a patient's perceived secondary effects and developing appropriate care.

RESUMO

OBJECTIVE: To assess the prevalence of and factors associated with squamous intraepithelial lesions and condyloma [human papillomavirus (HPV)-related lesions) in HIV-infected patients. DESIGN: A cross-sectional study in a tertiary-care university hospital conducted in 516 consecutive outpatients. INTERVENTION: A systematic examination for macroscopic HPV-related lesions through anoscopy with histological confirmation, evaluation of dysplasia and HPV typing. Sexual behaviours were assessed using a semi-directive questionnaire. RESULTS: Of 473 patients examined, (200 homosexual men, 123 heterosexual men, 150 women), 108 (23%) had histologically confirmed anal HPV-related lesions (36, 15 and 11% of the respective populations), including 51 (47%) with only endoanal localization. Among these 108 patients, histological dysplasia of grades I or II and grade III were noted in 59 and two patients, respectively, invasive endoanal cancer in one; three patients also had high-risk oncogenicity HPV without dysplasia. Independent identified associated factors of HPV-related condyloma were the number of incidents of sexual intercourse per month [odds ratio (OR) 1.04; 95% confidence interval (CI) 1.01-1.06], CD4 cell count below 200 x 10 cells/l (OR 3.22; 95% CI 1.37-7.60), history of anal HPV lesion (OR 4.57; 95% CI 2.13-9.81), and receptive anal intercourse (OR 2.30; 95% CI 1.11-4.77). The two latter factors remained associated with histological dysplasia (OR 2.82; 95% CI 1.38-5.76 for history of anal condyloma, and OR 4.29; 95% CI 2.18-8.44 for receptive anal intercourse). CONCLUSION: The high rate of condyloma and histological dysplasia seen argues for a systematic screening for these lesions in HIV-infected individuals.

RESUMO

AIMS: To analyse the characteristics of infective endocarditis (IE) in patients with diabetes mellitus (DM), and to evaluate the prognostic significance of DM according to insulin use. METHODS AND RESULTS: A total of 559 patients with definite IE including 75 patients (13%) with DM (insulin use n = 22; oral antidiabetic n = 53) were evaluated. Comparison of insulin-DM, oral-DM, and non-DM patients showed an older age (66 +/- 13, 66 +/- 10, 58 +/- 17, respectively; P = 0.004) in DM patients, and more frequent IE on prosthetic valves (32, 11, and 15%, respectively; P = 0.068) in insulin-DM patients. Oral streptococci (0, 8, and 18%, respectively; P = 0.016) were less frequently the causative organism than staphylococci (64, 26, and 29%, respectively; P = 0.002) in insulin-DM patients. Vegetations, dehiscence, abscess, and regurgitation rates did not differ among the three groups, nor did cardiac surgery rates (32, 47, and 48%, respectively; P = 0.334), but in-hospital mortality was higher in insulin-DM patients (50, 19, and 15%; P < 0.001). In multivariable analysis, independently of other determinants of death (age, IE location, Staphylococcus aureus, history of heart failure, immunosuppression, creatinine serum), insulin-DM was a predictor of death (OR, 4.69; 95% CI, 1.77-12.44), whereas oral-DM was not. CONCLUSION: IE prognosis in insulin-DM patients is poor due to the coexistence of host and pathogen factors. Insulin-DM patients with IE may require specific management.

RESUMO

Approximately 50,000 valve replacement operations take place in Europe annually and almost as many valve repair procedures. Previous European guidelines on management of patients after valve surgery were last published in 1995 and were limited to recommendations about antithrombotic prophylaxis. American guidelines covering the broader topic of the investigation and treatment of patients with valve disease were published in 1998 but devoted relatively little space to post-surgical management. This document represents the consensus view of a committee drawn from three European Society of Cardiology (ESC) Working Groups (WG): the WG on Valvular Heart Disease, the WG on Thrombosis, and the WG on Rehabilitation and Exercise Physiology. In almost all areas of patient management after valve surgery, randomized trials and meta-analyses do not exist. Such randomized trials as do exist are very few in number, are narrowly focused with small numbers, have limited general applicability, and do not lend themselves to meta-analysis because of widely divergent methodologies and different patient characteristics. Recommendations are therefore almost entirely based on non-randomized studies and relevant basic science.

RESUMO

BACKGROUND: Persistent low CD4(+) cell counts are observed in 5%-27% of patients treated for human immunodeficiency virus (HIV)-1 infection despite their having prolonged undetectable plasma viral loads. METHODS: To understand the possible mechanisms of this discordant immunological situation, a prospective transsectional case-control study was designed. HIV-1-infected subjects who had a plasma viral load <200 copies/mL for >1 year were considered to be case patients if their CD4(+) cell count was <250/mm(3); control patients had CD4(+) cell counts >500/mm(3) and were matched by sex, age, and nadir CD4(+) cell count to case patients. T cell proliferation after stimulation with various antigens, T cell subset counts, T cell rearrangement excision circles (TRECs), T cells undergoing apoptosis, cytokines influencing apoptosis, and cellular proviral DNA and plasma viral RNA persistence were assessed. RESULTS: Compared with the 19 control patients, the 19 case patients had undistinguishable lymphoproliferative responses to candidin and cytomegalovirus, fewer naive CD4(+) cells (CD45RA(+)62L(+), 23%+/-13% vs. 47%+/-14%; P<.0001), lower thymic output (1.28 vs. 3.95 TRECs/microL of blood; P=.0015), increased cell death by apoptosis (spontaneous, 23.2%+/-8.3% vs. 11.9%+/-8.4% [P=.02]; Fas induced, 38.6%+/-13.7% vs. 16.4%+/-8.0% [P=.004]), higher levels of plasma soluble tumor necrosis factor receptor II (9.6 vs. 5.3 ng/mL; P=.0058), and undistinguishable plasma HIV-1 and cellular proviral DNA loads. CONCLUSIONS: The mechanisms responsible for the low-level regeneration of CD4(+) cells involve, at least, deficiency in the regeneration of central CD4(+) cells and excessive apoptosis.

RESUMO

Tenofovir disopril fumarate, a new nucleotide analogue against human immunodeficiency virus-1 (HIV-1), can induce hypophosphataemia, the mechanism of which is unclear. Moreover, a renal tubulopathy can occur in long-term treated patients, as observed in 2 HIV-1-infected patients after 12 months of tenofovir therapy, with polyuria-polydipsia, proteinuria, glycosuria and amino-aciduria, which resolved after discontinuation of tenofovir. The risk of renal tubulopathy symptoms in patients on long-term tenofovir therapy should be noted.

RESUMO

Indinavir and nelfinavir plasma levels were studied in 407 patients having plasma HIV RNA <500 copies/mL after 4 months of treatment with these drugs. For each drug, an observed/predicted (O/P) ratio was calculated between individual and mean time-adjusted population plasma drug levels. The relationship between the O/P ratio and the risk of rebound of plasma HIV RNA >500 copies/mL beyond month 4 was studied using Cox proportional hazard models. Median follow-up was 20 months. There was no association between indinavir plasma levels and risk of virologic rebound, whereas low nelfinavir + M8 (active nelfinavir metabolite) plasma levels were associated with a higher risk of virologic rebound. In multivariate analysis, the adjusted relative hazard of virologic rebound for patients with an O/P ratio of nelfinavir + M8 metabolite <0.8 compared with others was 2.2 (P = 0.01). In some patients, plasma levels of nelfinavir sufficient to achieve early viral response may not be sufficient to maintain it in the long term. This may be related to insufficient compliance with dietary recommendations. Monitoring of nelfinavir plasma levels thus seems useful, even in patients having early virologic response.

RESUMO

The distribution of risk factors for cardiovascular disease in patients aged 35-44 years who were treated for human immunodeficiency virus type 1 (HIV-1) infection was compared with that for a population-based cohort. HIV-1-infected men treated with a protease inhibitor-containing regimen (n=223), compared with HIV-1-uninfected men (n=527), were characterized by a lower prevalence of hypertension, a lower mean high-density lipoprotein cholesterol level, a higher prevalence of smoking, a higher mean waist-to-hip ratio, and a higher mean triglyceride level. No difference was found for total plasma or low-density cholesterol levels, nor for the prevalence of diabetes. Similar trends were observed among female subjects. The predicted risk of coronary heart disease was greater among HIV-1-infected men (relative risk [RR], 1.20) and women (RR, 1.59; P<10(-6) for both), compared with the HIV-1-uninfected cohort. The estimated attributable risks due to smoking were 65% and 29% for HIV-1-infected men and women, respectively. Because most HIV-1-infected people will ultimately need antiretroviral therapy, risk factors for cardiovascular disease should be determined at the initiation of treatment, and interventions should be considered for all patients who have them.

RESUMO

CONTEXT: Since the first modern clinical description of infective endocarditis (IE) at the end of the 19th century, the profile of the disease has evolved continuously, as highlighted in epidemiological studies including a French survey performed in 1991. OBJECTIVE: To update information gained from the 1991 study on the epidemiology of IE in France. DESIGN AND SETTING: Population-based survey conducted from January through December 1999 in all hospitals in 6 French regions representing 26% of the population (16 million inhabitants). PATIENTS: Three hundred ninety adult inpatients diagnosed with IE according to Duke criteria. MAIN OUTCOME MEASURES: Incidence of IE; proportion of patients with underlying heart disease; clinical characteristics; causative microorganisms; surgical and mortality outcomes. RESULTS: The annual age- and sex-standardized incidence was 31 (95% confidence interval [CI], 28-35) cases per million, not including the region of New Caledonia, which had 161 (95% CI, 117-216) cases per million. There was no previously known heart disease in 47% of the cases. The proportion of prosthetic-valve IE was 16%. Causative microorganisms were: streptococci, 48% (group D streptococci, 25%; oral streptococci, 17%, pyogenic streptococci, 6%); enterococci, 8%; Abiotrophia species, 2%; staphylococci, 29%; and other or multiple pathogens, 8%. Blood cultures were negative in 9% and no microorganism was identified in 5% of the cases. Early valve surgery was performed in 49% of the patients. In-hospital mortality was 16%. Compared with 1991, this study showed a decreased incidence of IE in patients with previously known underlying heart disease (20.6 cases per million vs 15.1 cases per million; P<.001); a smaller incidence of oral streptococcal IE (7.8 cases per million vs 5.1 cases per million; P<.001), compensated by a larger proportion of IE due to group D streptococci (5.3 cases per million vs 6.2 cases per million; P =.67) and staphylococci (4.9 cases per million vs 5.7 cases per million; P =.97); an increased rate of early valve surgery (31.2% vs 49.7%; P<.001); and a decreased in-hospital mortality rate (21.6% vs 16.6%; P =.08). CONCLUSION: Although the incidence of IE has not changed, important changes in disease characteristics, treatment, and outcomes were noted.
