How to improve the quality of a disease management program for HIV-infected patients using a computerized data system. The Saint-Antoine Orchestra program.

OBJECTIVES: The emergence of non-AIDS-related events in the HIV-infected population experiencing a longer life expectancy implies the implementation of a comprehensive approach of HIV clinical management through better access to care, prevention, and early diagnosis of co-morbidities. METHODS: The Orchestra program is a computer-assisted HIV care and support tool implemented since December 2004 in the outpatient clinic of a University Hospital set in Paris, France. The intervention aims at improving access to HIV information care and support specifically targeted five areas of actions: cardiovascular risk factors; gynecological follow-up; anti-hepatitis B virus (HBV) vaccine coverage; sexuality and prevention of sexually transmitted infections; and compliance to antiretrovirals. The impact of this program was examined prospectively on a "before-after" basis after a two-year implementation. RESULTS: In the two-year period, 1717 patients were regularly followed. The level of the database information significantly increased in time (low density lipoprotein (LDL) cholesterol and glycemia were informed in 74% of patients at inclusion versus 95% at two years, and 83% versus 97%, p < 0.001, respectively). The number of targeted interventions was also higher. For eligible women, papanicolaou smears and mammography were prescribed in 52% of cases after intervention, versus 44% at inclusion, p0.04 and 83% versus 50%, p < 0.001, respectively. Indicators of care eventually improved significantly. Initially 72% non-adherent patients declared to be adherent after the intervention ( p < 0.001) and 67% of patients with initial LDL-hypercholesterolemia normalized their LDL level within two years ( p < 0.001). CONCLUSION: The Orchestra program has provided a unique opportunity to assess and improve prevention and management of co-morbidities in HIV patients.

Switching the nucleoside reverse transcriptase inhibitor backbone to tenofovir disoproxil fumarate + emtricitabine promptly improves triglycerides and low-density lipoprotein cholesterol in dyslipidaemic patients.

OBJECTIVES: To assess the impact of switching to tenofovir disoproxil fumarate + emtricitabine on lipid parameters. METHODS: HIV-infected patients with plasma viral load <400 copies/mL, fasted triglycerides from 2.3 to 11.4 mmol/L and/or fasted low-density lipoprotein (LDL)-cholesterol >4.1 mmol/L were randomized to switch the nucleoside reverse transcriptase inhibitor (NRTI) backbone to fixed-dose combination tenofovir disoproxil fumarate + emtricitabine or to maintain the baseline antiretroviral regimen (the control group). The study has been registered with ClinicalTrials.gov under the identifier NCT00323492. RESULTS: Ninety-one patients were included in the intent-to-treat (ITT) analysis with triglycerides 2.4 mmol/L and LDL-cholesterol 4.0 mmol/L (median values). At week 12, the median changes from baseline of triglycerides were -0.5 mmol/L (-25%; n = 46) and -0.1 mmol/L (-6%; n = 45) in the tenofovir disoproxil fumarate + emtricitabine and control groups, respectively, indicating a difference of -0.4 mmol/L (P = 0.034) [95% confidence interval (CI): -0.9 to -0.0]. Similarly for LDL-cholesterol, changes of -0.4 mmol/L (-9%) and -0.1 mmol/L (-1%) were observed in the tenofovir disoproxil fumarate + emtricitabine and control groups, respectively, indicating a difference of -0.4 mmol/L (P = 0.031) [95% CI: -0.7 to -0.0]. The proportion of patients with LDL-cholesterol >4.1 mmol/L decreased from 48% at baseline to 26% at week 12 in the tenofovir disoproxil fumarate + emtricitabine group versus no change in the control group. No virological failure was observed during the study. CONCLUSIONS: Switching to tenofovir disoproxil fumarate + emtricitabine in dyslipidaemic HIV-infected patients improves triglycerides and LDL-cholesterol.

High rate of virologic suppression with raltegravir plus etravirine and darunavir/ritonavir among treatment-experienced patients infected with multidrug-resistant HIV: results of the ANRS 139 TRIO trial.

BACKGROUND: The introduction of 2 or 3 fully active drugs in human immunodeficiency virus (HIV)-infected patients receiving failing antiretroviral therapy is a key determinant of subsequent treatment efficacy. The aim of this study was to assess the safety and efficacy of a regimen containing raltegravir, etravirine, and darunavir/ritonavir for treatment-experienced patients infected with multidrug-resistant HIV. METHODS: Patients enrolled in this phase II, noncomparative, multicenter trial were naive to the investigational drugs and had plasma HIV RNA levels >1000 copies/mL, a history of virologic failure while receiving nonnucleoside reverse-transcriptase inhibitors (NNRTI), > or =3 primary protease inhibitor and nucleoside reverse transcriptase inhibitor (NRTI) mutations, and < or =3 darunavir and NNRTI mutations. The primary end point was the proportion of patients with plasma HIV RNA levels <50 copies/mL at 24 weeks. RESULTS: A total of 103 patients enrolled in the study. At baseline, genotypic resistance profiles showed a median of 4 primary protease inhibitor mutations, 1 NNRTI mutation, and 6 NRTI mutations. In addition to the investigational drugs, 90 patients (87%) received optimized background therapy that included NRTIs (86 patients) or enfuvirtide (12 patients). At week 24, 90% of patients (95% confidence interval, 85%-96%) had an HIV RNA level <50 copies/mL. At week 48, 86% (95% confidence interval, 80%-93%) had an HIV RNA level <50 copies/mL. The median CD4 cell count increase was 108 cells/mm(3). Grade 3 or 4 clinical adverse events were reported in 15 patients (14.6%). Only 1 patient discontinued the investigational antiretroviral regimen, because of an adverse event. CONCLUSION: In patients infected with multidrug-resistant virus who have few remaining treatment options, the combination of raltegravir, etravirine, and darunavir/ritonavir is well tolerated and is associated with a rate of virologic suppression similar to that expected in treatment-naive patients.

[Early diagnosis and prevention of comorbidities among HIV-infected patients: the Orchestra Saint-Antoine Program]. / Dépistage et prévention des comorbidités chez les patients infectés par le VIH: le programme Orchestra Saint-Antoine.

OBJECTIVES: The Saint-Antoine Orchestra Program aims at improving the clinical management of HIV-infected patients through access to care, prevention and early diagnosis of comorbidities. METHODS: The program was initiated in December 2004 on the whole database. The following topics were concerned: cardiovascular risk factors, gynecological follow-up, anti-HBV vaccinal coverage, sexuality and prevention of STIs, therapeutic adherence and counsels to travelers. The program included several actions: diffusion of information to patients, development of a computerized chart (alert pop-ups), individualized prescription advice and recommendations for specialist referral. RESULTS: The program was applied to 1959 patients whose initial characteristics were: mean age: 43+/-10 years; ratio M/W: 1466/493; European origin: 69%; sub-Saharan: 19%; mean duration of HIV infection: 9.3+/-6 years; naïve of antiretrovirals: 14%; mean CD4+count: 494+/-277/mm(3); HIV viral load inferior to 50 cp/ml: 62%. Among 1347 patients for whom cardiovascular risk factors were completely informed, 42% had two or more factors. In particular, 31% of them were smokers, 7% had an arterial pressure superior to 140/90 mmHg and 11% had LDL-cholesterolemia superior to 4.1 mmol/l. Among 1448 untreated patients, 70% were initially considered as adherent. Half of the concerned women had neither cervical smear nor mammography up to date. Among 67% patients with an informed complete HBV serology, 27% were seronegative among which 310 (86%) were eligible for the vaccine. Problems of sexual difficulties or prevention were initially discussed for 11% of patients. Among them, 14% had a problem of prevention and 148 (66%) recognized sexual difficulties. CONCLUSION: The initiation of the Saint-Antoine Orchestra program has provided a unique opportunity to assess and improve the prevention and management of comorbidities in HIV patients. Also, this program aimed to improve professional practices.

Major hypertriglyceridemia in HIV-infected patients on antiretroviral therapy: a role of the personal and family history.

BACKGROUND: Our aim was to identify factors predisposing HIV-infected patients on long-term antiretroviral therapy (ART) to major hypertriglyceridemia (HTG). PATIENTS AND METHODS: We conducted a retrospective, case-control study involving 76 HIV-infected patients with HTG, defined by 12-hour fasting plasma triglyceride (TG) > 4.5 mmol/l on at least one occasion, and 150 HIV-infected matched control patients with TG consistently below 1.8 mmol/l. RESULTS: Patients coinfected by the hepatitis C virus appeared to be protected from HTG. In addition to known predisposing factors for HTG in HIV-infected patients (ART and immune/viral status), patients with a history of excess body weight were twice as likely to have HTG (odds ratio [OR] 2.8, 95% confidence interval [CI]: 1.1-6.9); HTG was also more frequent in patients who had a first-degree relative with cardiovascular disease (CVD) or a major risk factor for CVD (OR = 3.6, CI: 1.3-9.9). CONCLUSION: By identifying subgroups of highly predisposed patients, appropriate lifestyle and dietary measures could be recommended on ART initiation.

[Predictive factors of virologic response to antiretroviral treatment with a protease inhibitor in HIV infection]. / Facteurs prédictifs de réponse virologique à un traitement antirétroviral avec inhibiteur de protéase au cours de l'infection à VIH.

OBJECTIVE: To investigate factors related to early virological response among a cohort of 224 patients who started a protease inhibitor (PI) for the first time. To determine which factors are associated with persistent response among patients with early response. PATIENTS AND METHODS: Early complete response was defined as an undetectable plasma viral load 2 to 3 months after treatment onset (< 400 copies/ml, Quantiplex HIV 2.0 Chiron diagnostics), incomplete response as at least 1 log reduction of viral load. In patients with an undetectable plasma viral load at 2 or 3 months, we also assessed the persistence of the response on the same regimen. Virology failure was defined by two consecutive viral load levels above the detection limit. RESULTS: In the total cohort, 66% of the patients had an early complete response, 11% a partial response and 23% no response. Complete virological response was significantly more frequent in naive (89%) than in pretreated (59%) patients (p < 0.001). Multivariate analysis of factors predictive of early response in pretreated patients (n = 169) showed that viral load (p = 0.001), the number of nucleoside analogs previously received (p = 0.06) and a full or partial treatment switch (p = 0.10) were associated with complete response. Analysis of later response in the 45 naive patients with prolonged follow-up showed that 22% had treatment failure after 3 to 16 months. None of the baseline variables (viral load, CD4+ cell count or nature of the PI) were associated with duration of response. The only factor associated with persistent response in pretreated patients was a low number of antiretroviral drugs previously received (log-rank test, p = 0.04). CONCLUSIONS: The absence of previous antiretroviral treatment as the main factor associated with an early complete virological response. In patients pretreated with nucleoside analogs who presented early virological success, the number of drugs previously received, often associated with full or partial switch of nucleoside analog, significantly influence the persistence of response to a given triple-drug regimen.

Long-term outcome and treatment modifications in a prospective cohort of human immunodeficiency virus type 1-infected patients on triple-drug antiretroviral regimens. Triest Cohort Investigators.

We designed a cohort in order to assess the long-term effects of triple-drug antiretroviral combinations in 608 patients infected with human immunodeficiency virus type 1 (HIV-1). We recruited patients who had been previously treated with nucleoside analogues as well as treatment-naive patients who were starting triple-drug antiretroviral combinations consisting of nucleoside analogues, either alone or in combination with a protease inhibitor. After a median follow-up time of 22 months, the incidence rates of acquired immune deficiency syndrome-defining events and death were, respectively, 6.9 (95% confidence interval [CI], 5.3-8.8) and 2.9 (95% CI, 1.9-4.2) per 100 person-years. Advanced clinical stage of disease (P=.004), a low CD4(+) cell count (P=.002), and a low quality-of-life score (P=.001) at baseline were independent predictors of clinical progression. The initial triple-drug combination was modified a total of 647 times in 321 patients. The only independent predictor of treatment modification was previous exposure to a nucleoside analogue in patients who did not receive a new nucleoside analogue at inclusion (P=.001). Plasma HIV RNA values below 500 copies/mL were obtained in 88% of the treatment-naive patients and in 57% of the previously treated patients (P<.001). Compared with previously treated patients who received > or = 1 new nucleoside analogue at enrollment, previously treated patients who did not receive a new nucleoside analogue at enrollment were twice as likely to have plasma HIV RNA values >500 copies/mL at the last visit (adjusted odds ratio [OR], 1.8; 95% confidence interval [CI], 1.2-2.8), and the antiretroviral-naive patients were significantly less likely to have plasma HIV RNA values >500 copies/mL at the last visit (adjusted OR, 0.2; 95% CI, 0.1-0.4).

Treatment of non-meningeal cryptococcosis in patients with AIDS. Centre d'Informations et de Soins de l'Immunodéficience Humaine de l'Est Parisien.

Amphotericin B, alone or combined with flucytosine, is the reference curative treatment for neuromeningeal cryptococcosis associated with the acquired immune deficiency syndrome (AIDS). Treatment of non-meningeal forms is less well standardized. Out of 75 human immunodeficiency virus (HIV)-infected patients with cryptococcosis, 16 had no meningeal involvement. One died before receiving any treatment, another received amphotericine B and recovered, and the remaining 14 received curative therapy with fluconazole (200-400 mg/day); 11 of the latter entered complete remission, while three deteriorated during the first week of treatment but recovered on amphotericin B combined, in two cases, with fluconazole. Only one relapse occurred during maintenance treatment with low-dose fluconazole (100 mg/day). No adverse effects of fluconazole treatment were observed. One of the patients on amphotericin B developed acute renal impairment requiring drug withdrawal. These results suggest that first-line fluconazole therapy is effective and well tolerated in patients with AIDS-associated non meningeal cryptococcosis.

Pulmonary cryptococcosis: localized and disseminated infections in 27 patients with AIDS.

We reviewed the records of 85 patients infected with both human immunodeficiency virus and Cryptococcus neoformans. Twenty-seven patients (32%) had pulmonary cryptococcosis. C. neoformans was cultured from bronchoalveolar lavage (BAL) or pleural fluid in 25 cases; the remaining two patients had cryptococcal antigen (CA) detected in BAL fluid and C. neoformans cultured from other sites. All but one of the 27 patients had detectable CA in serum. The CD4+ lymphocyte count was low in all cases (median, 24/mm3). Clinical manifestations of pulmonary cryptococcosis included fever (94%), cough (71%), dyspnea (7%), expectoration (4%), chest pain (2%), and hemoptysis (1%). Diffuse interstitial opacities (70.5%), focal interstitial abnormalities, alveolar opacities, adenopathies, cavitary lesions, and pleural effusions were evident. Outcome was poor (mean survival time, 23 weeks) despite treatment. Patients with localized pulmonary cryptococcosis appeared to have a higher CD4+ lymphocyte count, an earlier diagnosis, lower serum CA titers, fewer previous or concomitant infections, and a better prognosis than patients with disseminated cryptococcosis.
