RESUMEN
OBJECTIVES: To assess the effectiveness of the adjunction of a one-gram single dose of ciprofloxacin to a symptomatic treatment for the early treatment of uncomplicated diarrhea during military operations of the French service members in Africa. PATIENTS AND METHODS: This phase IV, multicentric, randomized, open-label, controlled trial was conducted in Chad, Mali, and in Central African Republic. A total of 267 French service members having at least one loose stool in the previous 24 hours were enrolled from May 2015 to June 2016. Participants were randomized to receive ciprofloxacin 1 g and a symptomatic treatment (racecadotril 100 mg three times a day and ad libidum oral rehydration solution) or a symptomatic treatment alone. The primary outcome was the duration of the diarrhea. Secondary outcomes were evaluated at the 72-hour endpoint and included recovery status, number of loose stools, frequency and duration of associated symptoms and safety of treatments. RESULTS: Among 267 participants, 242 completed the trial. Participants receiving ciprofloxacin and a symptomatic treatment (n = 124) were significantly more likely to be cured at the endpoint than those who only received a symptomatic treatment (118): 94.4 % versus 74.6 % (OR = 5.7; 95 %CI: [2.4-13.6]; p < 10-3). The antibiotic therapy reduced the average diarrhea duration by 30 % (p = 10-4). Fever at inclusion was associated with a longer episode (HR = 0.61; 95 %CI: [0.41-0.89]; p = 0.012). No adverse event of medications was reported. CONCLUSION: A single dose of ciprofloxacin was effective and safe in treating uncomplicated diarrhea among service members in Africa.

INTRODUCTION: Improved knowledge of prediabetic subjects' profile and their risk of developing type 2 diabetes mellitus (T2DM) would enhance secondary prevention. The primary objective is to describe factors associated with incident T2DM in subjects with pre-diabetes diagnosed in primary care. METHODS AND ANALYSIS: The study is based on Reunion Island, a French overseas region that experiences a particularly high disease burden of T2DM. This is an observational, non-randomised prospective cohort study conducted in primary care in which private general practitioner (GP) investigators recruit participants with pre-diabetes from their practices regardless of the initial motive for consultation. Pre-diabetes is defined by WHO criteria, that is, fasting plasma glucose between 1.10 g/L and 1.25 g/L and/or plasma glucose 2 hours after ingestion of 75 g of glucose (2-hour post load plasma glucose) between 1.40 g/L and 1.99 g/L. The design is based on an annual follow-up by the GP (according to French National Health Authority recommendations) with collection of clinical and laboratory data and specific lifestyle questionnaires answered by telephone at three time points: inclusion, and at 2-year and 5-year follow-up visits. Follow-up clinical and laboratory data are collected by the investigating GP as part of the study, and study-specific laboratory collections (serum, DNA and urine) will be obtained 2 and 5 years after inclusion. The primary outcome is transition to T2DM. ETHICS AND DISSEMINATION: This protocol has been approved by the research ethics committee of Saint Etienne (CPP Saint Etienne reference number: 2019-03). Enrolment began in August 2019. Results will be disseminated in at least three papers published in peer-reviewed medical journals, one oral communication and a large-scale communication to the local population and healthcare policymakers. TRIAL REGISTRATION NUMBER: NCT04463160 and ID-RCB 2018-A03106-49.

This study presents the 6-year follow-up of French gendarmes exposed to the chikungunya (CHIK) infection in 2006 on Reunion Island. The aim was to see to what extent the subjective health differences observed in 2008 (30 months after infection) between CHIK infected (CHIK+) and noninfected (CHIK-) gendarmes still persisted in 2012, and to investigate a possible return to a pre-CHIK health status for CHIK+ subjects. Gendarmes were contacted by mail in 2012 and asked to complete a self-questionnaire asking for morbidity, health care and medicines consumption since the last follow-up in 2008. Quality of life (QoL) after 6 years was evaluated using the SF-36 scale. In comparison with CHIK- subjects (n = 171), CHIK+ (n = 81) presented with higher rheumatic but also nonspecific morbidity such as headaches and fatigue associated with a large psychological impact, frequent depressive moods and social disabilities, leading to a significant impairment of the QoL and higher health care consumption. When restricted to CHIK+ subjects, comparing the data with that of 2008 showed persistent but decreasing self-reported rheumatic morbidity, and an increase over time of chronic discomfort (headache, fatigue) and depressive moods, resulting in no overall improvement in QoL. Despite possible cohort attrition bias, the comparability of CHIK+/CHIK- subjects allows the assumption of a long-term impact of CHIK infection with less chance of returning to a previous health status. Although these results may be specific to the 2006 virus strain, we recommend that public health strategies in the epidemic-prone countries include a response to the consequences of chronic post-CHIK disorders.

OBJECTIVE: Many suicide victims had contacts with an emergency department before their attempt. We aimed to determine whether patients coming to a psychiatric emergency department were well assessed concerning their suicidal risk, and to test an easy to fill in scale rapidly assessing suicidal risk. METHOD: We conducted a descriptive epidemiological survey in Marseille. The source population was all patients admitted to the psychiatric emergency department. We used a booklet containing three questionnaires for "nurse", "psychiatrist" and "patient". We estimated the suicidal risk using both a visual analogue scale (similar for patients and caregivers), and validated scales on self-assessment (scale of suicidality SBQ-R and the Beck Hopelessness Scale). RESULTS AND DISCUSSION: The questionnaire results have shown that people who visited a psychiatric emergency department presented a significant suicidal risk on several criteria: socio-demographic criteria (social isolation, low level of education, low number of people with a job), psychiatric history (rate of pre-existing psychiatric disorders significantly higher than in the general population, high proportions of family and personal history of suicide attempts, psychiatric hospitalizations, and people with a psychiatrist). Six percent of patients claimed to have come to an emergency unit for suicidal ideas but they were ten times more with a suicidal risk, according to the SBQ-R score. The suicidal risk self-assessed by patients on our visual analogue scale was well correlated with SBQ-R scale and Beck Hopelessness scale, but was not well correlated with the evaluation of caregivers. CONCLUSION: Hence, the analog scale we created is easy to use and seems to be a good tool for suicidal risk estimation when it is self-assessed by patients in our study population.

RESUMEN
This retrospective and longitudinal study evaluated the long-term hepatic tolerance of a nelfinavir (NFV)-antiretroviral combined regimen in 82 patients of the HCV-HIV Cohort of CISIH-Sud of Marseilles. Follow-up data (liver enzyme levels, CD4 cell count, HIV viral load, and metabolic parameters) of patients treated with NFV on inclusion or during the follow-up of the cohort were analyzed under treatment over 24 months. Comparisons were performed with X2 or Kruskal-Wallis tests. At baseline (n = 82), the median exposure to NFV was 4.1 months; 58 patients received NFV combined with NRTI and 24 with NNRTI. The median CD4 cell count was 337/mm3 [interquartile range (IR): 216-480) and 39.7% had an undetectable HIV RNA level. Qualitative HCV PCR was positive in 91% of the patients and 19/51 patients with liver biopsy were F3-F4. Median alanine and aspartate aminotransferase (ALAT, ASAT), gamma-glutamyltransferase (GT), and alkaline phosphatase (ALP) were 46 UI/liter (IR: 36-76), 55 UI/liter (IR: 32-97), 97 UI/liter (IR: 50-194), and 88 UI/liter (IR: 72-104), respectively, with 76% of the patients with ALAT/ASAT grade <2. Median follow-up was 23 months (IR: 13.8-37). No significant difference was observed in the distribution of ALAT, ASAT, GT, and ALP as well as of ALAT/ASAT grades over the 24-month study period. Patients treated with NFV + NNRTI had significantly higher GT and ALP levels at baseline with no significant increase during follow-up. Cholesterol, triglyceride, and glycemia distributions remained stable over time. In conclusion, this study showed a good hepatic and metabolic tolerance of a long-term NFV-combined regimen in HIV-HCV coinfected patients.

BACKGROUND: HIV lipodystrophy syndrome, characterized by a significant excess of visceral adiposity and a reduced subcutaneous fat mass in association with insulin resistance and dyslipidemia, still affects the majority of antiretroviral-treated HIV-infected patients. The therapeutic management of this syndrome has not yet been well established. Benfluorex is known to decrease insulin resistance with no side effects on lactate levels in HIV-negative patients. METHOD: We conducted an open-label study of benfluorex (150 mg, 2-3 times a day) that was prescribed for 60 HIV-infected patients who were diagnosed with glucose metabolism abnormalities by oral glucose tolerance test (OGTT); 47 of these patients had visceral fat accumulation measured by computed tomography (VAT). Median follow-up was 12 months (interquartile range [IQR] = 6-12 months). The great majority of patients (90%) were treated with at least triple therapy (in 70% the therapy included at least one PI), with a nonsignificant change over the study period. RESULTS: Added to antiretroviral therapy, benfluorex improved OGTT in 47/60 cases, including total normalization in 34/60 without lactate concentration modification. A trend toward a decrease in VAT distribution was observed (p =.06). No significant difference was observed in subcutaneous fat distribution, although an increase in subcutaneous thigh adipose tissue was observed in 17/47 (36.2%) cases and 6 patients (12.7%) presented both subcutaneous fat increase and VAT decrease.

To investigate employment levels and identify barriers to work among persons living with HIV/AIDS in France in 2001, we conducted a cross-sectional study among HIV-infected patients seen in the hospital outpatient clinics of the two French regions most affected: Ile-de-France (IDF) and Provence-Alpes-Côte-d'Azur (PACA). Of the 840 outpatients included in the study, 58.8% in IDF and 46.8% in PACA were currently employed, and 28.1 and 47.8%, respectively, were receiving disability benefits. Among unemployed patients, 32.1% in IDF and 29.6% in PACA reported that they planned to (re)enter the workforce. Current and planned employment status were associated with characteristics indicative of the patients' social and demographic situation before the HIV diagnosis (region of residence, educational level, HIV transmission group, age, nationality) and with their health status at the interview (HIV progression, HCV co-infection). Receiving disability benefits was negatively associated with plans to return to work. HIV-related discrimination at work was reported by 11.9% of the patients in IDF and 9.2% in PACA, and was not associated with occupational status. Thus, social interventions should seek to prevent patients, particularly the most socially vulnerable, from leaving their jobs at acute stages of their illness and should promote (re)entry into the workforce among unemployed patients.

The objective of this study was to estimate the relative impact of hospitalization for depressive syndrome (DS) on all causes of hospitalization and characterize individuals more likely to experience hospitalization for DS in the French cohort study, Manif 2000, of patients HIV infected through injection drug use. We selected all patients followed-up to the 24-month visit (C24) who missed no more than one visit. Using medical records, dates and causes of hospitalizations, were collected retrospectively. A Poisson regression model based on generalized estimating equations was used to identify factors associated with hospitalization for DS. During the study period, 223 hospitalizations were recorded for 120 of the 335 selected patients. DS was the second reason for hospitalization after infections, accounting for 14.3% of the total number of hospitalizations. DS was reported in 32 hospitalizations and involved 24 patients, five of them being hospitalized more than once for the same cause. Factors independently associated with hospitalization for DS were history of multiple incarceration (RR = 2.1, 95% CI: 1.0-4.7), polydrug use (RR = 2.6, 95% CI: 1.1 -5.9) and lack of stable relationship (RR = 4.2, 95% CI: 1.6- 11. 1). In the HAART era, DS represents an important cause of hospitalization of HIV-infected injecting drug users, mainly concerning patients presenting no stable relationship and signs of social instability. Scheduled psychiatric consultations for these patients would permit us to identify those for whom major depression might lead to hospitalization and provide them with timely and appropriate care.

PURPOSE: To evaluate tolerance and efficacy of an open-label interferon-ribavirin treatment and their determinants in 62 HCV-HIV coinfected patients in routine followup. METHOD: Patients received at least 6 and up to 12 months of combination interferon alpha-2b (peg or not) plus ribavirin. Determinants of therapeutic success were estimated by a multivariate logistic regression. RESULTS: Five patients stopped the study, 4 were lost to follow-up, and 53 participated in the entire therapeutic protocol. Among these 53, the end-of-treatment results showed complete clearance of HCV-RNA in 17 (32%). A sustained virologic response (SVR) after 6 or 9 months was observed in 9 (17%) patients, 3 relapsed, and data were not available for 5. Genotype 3a (odds ratio [OR] = 14.4; confidence interval [CI] = 1.84-110.3) favored SVR and treatment with protease inhibitor (PI) therapeutic resistance (OR = 14.4; CI = 1.01-200); as well, a higher fibrosis score tended to increase resistance (p =.11). Adverse events were reported by 24/53 patients (45.3%). CONCLUSION: HCV therapy associating interferon and ribavirin in HCV-HIV coinfected patients is well accepted even if tolerance is moderate. Treatment permitted SVR in at least 17% of the cases. This is likely when patients initiate treatment at the early fibrosis stage and are infected with genotype 3a. The potential interaction with PI therapy should be explored.

OBJECTIVE: To describe the causes of hospitalization and mortality among the MANIF 2000 cohort study, composed of HIV-infected patients contaminated through intravenous drug use. METHOD: Data collection with a standardized questionnaires with clinical, biological, therapeutic and psycho-sociologic data on inclusion and every six months. Dates and causes of hospitalization and death were collected retrospectively by nurses from the hospital clinical records. Comparison were made using the chi(2) or Mann-Whitney tests with 5% significance threshold. RESULTS: The MANIF 2000 cohort study included, between October 1995 and June 1998, 467 patients with a median age of 33 years, 30% of whom were women. On inclusion, 42.2% were still injecting drugs (half of them were on substitution therapy), 10.5% had stopped injections of drugs, 32% exhibited more than 500CD4/mm(3) and 55.7% had not taken antiretroviral treatment. As of December 31(st) 1999, 21 patients had died, i.e. a mortality rate of 19% persons/years of follow-up (10-fold greater than that expected in the general population). Less than 5 deaths were due to HIV (n=4). Suicides and liver disease each represented the same number of deaths. Out of the 335 patients not having missed more than one follow-up throughout the 24 month period, 120 had been hospitalized at least once (n=223 hospitalizations), i.e., a hospitalization rate of 2.8 per 100 persons/month of follow-up. A quarter of hospitalizations were due to benign infections or stage B or C pathologies according to the 1993 classification of HIV infections and one hospitalization out of 5 was due to psychiatric problems (in majority depressive syndromes). Other predominant causes were worsening of general state of health, trauma, problems related to alcohol consumption, drugs abuse or hepatic decompensation. CONCLUSION: HIV-infected patients contaminated by intravenous drug use represent a particular population that cumulates many risk factors and which requires careful monitoring of co-morbidities such as hepatic and psychiatric diseases in order to avoid premature death.

OBJECTIVE: To describe trends in the evolution of causes of death in a cohort of HIV-infected patients before and after the introduction of highly active antiretroviral treatment (HAART). METHODS: This descriptive study concerned all the patients of the Aquitaine cohort who died between 1995 and 1997. Causes of deaths were grouped into 13 'deaths due to an AIDS-defining underlying cause', and eight 'non AIDS' categories. Comparisons were performed between two comparable periods of 18 months, January 1995-June 1996 and July 1996-December 1997 to focus on changes introduced by the prescription of HAART in June 1996. RESULTS: Five hundred and thirty-two deaths were notified in 36 months for a total of 3687 patients. The comparison between causes of deaths before and after June 1996 showed a significant difference between the two periods with a decreasing proportion of AIDS causes of death, from 82.7% to 72.2% (p = 0.007). CONCLUSION: HAART treatment has reduced the number and percentage of deaths due to AIDS-related causes among persons who died with HIV infection in South-western France.

BACKGROUND: Clinical guidelines for the prevention of opportunistic infections in human immunodeficiency virus (HIV)-infected individuals have been developed on the basis of natural history data collected in the USA. The objective of this study was to estimate the incidence of primary opportunistic infections in HIV-infected individuals in geographically distinct cohorts in France. METHODS: We conducted our study on 2664 HIV-infected patients from the Tourcoing AIDS Reference Centre and the hospital-based information system of the Groupe d'Epidémiologie Clinique du SIDA en Aquitaine enrolled from January 1987 to September 1995 and followed through December 1995. We estimated: (1) CD4-adjusted incidence rates of seven primary opportunistic infections in the absence of prophylaxis for that specific infection or any antiretroviral drugs other than zidovudine; and (2) CD4 lymphocyte count decline. RESULTS: The highest incidence rates for all opportunistic infections studied occurred in patients with CD4 counts < 200/microl. With CD4 counts < 50/microl, the most common opportunistic infections were toxoplasmic encephalitis (12.6 per 100 person-years) and Pneumocystis carinii pneumonia (11.4 per 100 person-years). Mycobacterium tuberculosis was the least common opportunistic infection (< 5.0/100 person-years). Even with CD4 counts > 300/microl, cases of Pneumocystis carinii pneumonia and toxoplasmic encephalitis were reported. The mean CD4 lymphocyte decline per month was 4.6 cells/microl. There was a significant association between HIV risk behaviour and the incidence of cytomegalovirus infection, between calendar year and the incidence of Pneumocystis carinii pneumonia, toxoplasmic encephalitis and Candida esophagitis, and between geographical area and the incidence of Pneumocystis carinii pneumonia and cytomegalovirus infection. CONCLUSIONS: Geographical differences exist in the incidence of HIV-related opportunistic infections. These results can be used to define local priorities for prophylaxis of opportunistic infections.

OBJECTIVE: To describe the viroimmunologic response and its prognostic factors 6 months after initiating triple antiretroviral therapy in a cohort of HIV-1-infected patients. METHODS: Positive virologic response during follow-up (VL+) was defined as plasma HIV RNA level <500 copies/ml and positive immunologic response (CD4+) as an increase of CD4+ count of at least 50 cells/mm3. Four categories of response were defined: VL+/CD4+; VL+/CD4-; VL-/CD4+ and VL-/CD4-. Prognostic factors were studied through a polytomous logistic regression (VL-/CD4-, as reference). RESULTS: Baseline characteristics of the 478 studied patients were: 22% at AIDS stage, 77% pretreated, median CD4+ cell count 195/mm3 and HIV RNA level 4.42 log. At 6 months 37.5% were VL+/CD4+; 15.7% VL+/CD4-; 23.8% VL-/CD4+ and 23.0% VL-/CD4-. Baseline HIV RNA level was associated to a higher risk of VL-/CD4+ response. More advanced age was associated with a higher risk of isolated immunologic failure (VL+/CD4-), whereas pretreatment and saquinavir therapy were associated with a lower frequency of positive virologic response independently of immunologic response. CONCLUSION: HIV-RNA level, pretreatment, and saquinavir therapy were already known to be linked to therapeutic response. Based on our results, a high baseline HIV-RNA level is associated with isolated immunologic response; moreover, age should be of importance in treatment decision.

OBJECTIVE: To assess the performance of weight related nutritional markers (reported involuntary weight loss greater than 10%, measured weight loss and body mass index-BMI-) in predicting HIV disease progression. DESIGN: Multirisk cohort of HIV-1 infected patients. METHOD: The three nutritional variables were studied in Cox proportional hazard models as time dependant variables. RESULTS: The sample included 2376 subjects (median follow up: 43.1 months), of those 675 experienced an AIDS defining event. After adjustment for well known prognostic factors, the reported weight loss greater than 10% tripled the risk of progression to clinical AIDS (Hazard ratio [HR] 3.0. 95% confidence interval [CI] 2.5-3.7). For measured weight loss under 5%. between 5% and 10% and greater than 10% of baseline weight compared with no weight loss, hazard ratios were respectively 1.8 (CI 1.5-2.2), 2.6 (CI 2.1-3.2) and 5.1 (CI 4.1-6.4). The relative risks of AIDS were 1.7 (CI 1.3-2.2) for BMI between 17 kg/m2 and 18.5 kg/m2, 2.6 (CI 1.7-4.0) for BMI between 16 kg/m2 and 17 kg/m2 and 4.7 (CI 3.0-7.4) for BMI under 16 kg/m2. COMMENTS: Even a limited weight loss measured at a given time during follow up increases the risk of HIV progression; moreover, a simple cross-sectionnal measure of BMI has a good predictive value for subsequent development of clinical disease.

The objective of this study was to estimate the prevalence of and risk factors for clinical lipodystrophy (LD) and metabolic disorders in human immunodeficiency virus (HIV) type 1-infected patients. A cross-sectional survey of the Aquitaine Cohort was performed in January 1999. The clinical diagnosis of LD was categorized as fat wasting (FW), peripheral fat accumulation (FA), and mixed syndromes (MS). Of the 581 patients studied, 61% were treated with protease inhibitors. The overall prevalence of LD was 38% (95% confidence interval [CI], 32-42): prevalence of FW was 16% (95% CI, 13-18); of FA, 12% (95% CI, 10-15); and of MS, 10% (95% CI, 8-13). The prevalences of metabolic abnormalities were 49% (95% CI, 44-53) for lipid disorders and 20% (95% CI, 17-23), for glucose disorders. Factors associated with LD were age (for FW and MS), male sex (for FW), AIDS stage (for MS), body mass index (for FW and FA), waist-to-hip ratio (for FA and MS), and duration of antiretroviral treatment (for FW).

The aim of the study was to assess the performance of weight related nutritional markers [reported involuntary weight loss (WL) greater than 10%, measured WL and body mass index (BMI)] in predicting survival at AIDS stage. The three anthropometric indices were used as time dependent variables in Cox models to predict survival at AIDS stage. The studied sample included 630 HIV1-infected individuals of a prospective cohort of those 421 died (median survival at AIDS stage: 19.9 months). After adjustment for usual prognostic factors of survival, the reported WL greater than 10% was a pejorative predictor of survival (hazard ratio (HR) 2.4; 95% confidence interval (CI): 1.9-3.0). For measured WL < 5%, between 5 and 10% and > or = 10% of baseline weight compared with no WL, HR were respectively, 1.9 (CI: 1.4-2.6), 3.3 (CI: 2.4-4.4) and 6.7 (CI: 5.2-8.6). The HR of death were 2.2 (CI: 1.6-3.0) for BMI between 16 and 18.4 kg/m2 and 4.4 (CI: 3.1-6.3) for BMI < 16 compared to normal BMI (> or = 18.5). Even a limited WL measured at a given point in time during follow up increases the risk of death at the AIDS stage. Simple cross-sectional measures of BMI have a good predictive value of survival.

Background: Cases of lipodystrophy syndrome and metabolic disorders have been described since the onset of highly active antiretroviral therapy in HIV-infected patients. The aim of our study was to estimate the prevalence of lipodystrophy (LD) and to define the associated lipid profile of these patients. Methods: The following were determined for each patient: lipid profile (cholesterol and its subfractions, atherogenicity ratios, and triglycerides), blood glucose, and immunovirological markers (CD4(+) cell count and plasma viral load). Patients were classified into two groups on the basis of whether or not they presented with clinical signs of LD. Results: Among 233 HIV-infected patients included in the study, 61 cases (26.1%) of lipodystrophy (LD) were noted. Compared with non-LD patients (NLD), LD patients were older men (P<10(-4)) with a lower CD4(+) lymphocyte cell count (P<0.007) and more often at the AIDS stage (P<10(-3)) (OR=3.2 (95% CI: 1.47-6.2)). Multivariate analysis showed a correlation between LD cases and age (10 years older) (OR=1.78 (95% CI: 1.23-2.57), P<0.002) and the decrease in CD4(+) cell count (100 CD4(+)/mm(3) lower) (OR=1.31 (95% CI: 1.09-1.58), P<0.004). An analysis of lipid subfractions and atherogenicity ratios clearly indicated a proatherogenic lipid profile for the LD patients. Conclusions: The underlying physiopathological mechanism of LD is still unknown. However, the lipid profile of HIV-1-infected patients with a LD syndrome appears to place these patients at an increased risk of progression of atherosclerosis.
RESUMEN
OBJECTIVE: To describe the response to combinations of two nucleoside reverse transcriptase inhibitors (NRTIs) initiated early in the course of HIV infection under routine circumstances and to research prognostic factors indicating good virologic response. SETTING: Patients of the Aquitaine Cohort, a hospital-based open cohort that had been recruiting since 1987 in five public hospitals of the Aquitaine region in southwestern France. METHODS: Prospective cohort study of antiretroviral-naive patients with CD4+ cell counts >0.350 x 10(9)/L who started dual NRTI therapy between January 1996 and June 1997. Intent-to-treat analysis and multivariate logistic regression were used with data collected up to March 31, 1998. RESULTS: In this study, 130 patients were enrolled with a median follow-up of 14 months. At the time of first prescription, 79% were in U. S. Centers for Disease Control and Prevention (CDC) group A, 16% in group B, and 5% in group C; median CD4+ cell count was 0.466 x 10(9)/L and median HIV RNA level was 4.52 log10 copies/ml. The two main combinations used were zidovudine (AZT) plus zalcitabine (ddC; 38%) and AZT plus didanosine (ddI; 37%). At week 52, median CD4+ and HIV RNA responses were, respectively, +80 cells and -1.6 log; the proportions of patients with HIV RNA level <5000 and <500 copies/ml were 70% and 45%, respectively, and 96% of the patients had a CD4+ cell count >0.350 x 10(9)/L at that time. At their last follow-up, 3 patients had reached been diagnosed with full-blown AIDS and the AIDS-free survival probability at 1 year was 98.2% (95% confidence interval [CI], 93.1-99.6); 1 death had occurred. The only significant variable associated with an undetectable HIV RNA level at 1 year was a lower HIV RNA level at the first prescription of dual therapy. CONCLUSION: Our data indicate that dual nucleoside combinations could be a therapeutic option for patients diagnosed and observed during follow-up in the early course of HIV infection.
