Abstract
Objective To study the prognosis of HIV-infected patients with virological failure after exposure to three classes of antiretroviral drugs (ARVs). Design Cohort study. Setting: French Hospital Database on HIV. Patients Patients previously exposed to at least two nucleoside reverse transcriptase inhibitors (NRTIs), two protease inhibitors and one non-NRTI, with viral load (VL) values of >5000 copies/ml after the exposure criteria were met and a new treatment initiated between 1998 and 2001 with VL >5000 copies/ml. Main outcome measures Risk of new AIDS-defining-events (ADEs) or death from first introduction of a drug never used before occurring between 1998 and 2001 defined as baseline. Results The main baseline characteristics of the 1092 patients were: previous ADE in 49% of cases, median CD4 cell count 181 μl, median VL 4.9 log10 copies/ml, median duration of ARV therapy 5.0 years and previous exposure to a median of nine ARVs. The crude progression rates were 20.1/100 patient-years among patients included in 1998, 15.1 in 1999, 11.1 in 2000 and 8.6 in 2001. After adjustment for baseline characteristics, the calendar year of inclusion was associated with the risk of clinical progression ( P<0.001). When the types of newly available drugs used at baseline or during follow-up were introduced into the model, year of inclusion was no longer associated with the risk of clinical progression ( P=0.42), while exposure to amprenavir/r, lopinavir/r, abacavir or tenofovir was associated with a lower risk. Conclusions The clinical prognosis of heavily pretreated patients experiencing virological failure improved between 1998 and 2001, mainly thanks to the use of newly available drugs with more favourable resistance profiles.

Abstract
Whereas valacyclovir is widely used and is recommended by some authors in moderately immunocompromised HIV-infected patients, its use has not been validated by clinical studies. We report a case of herpes zoster in an HIV-infected patient for whom neurologic complication was not avoided despite valacyclovir therapy. Clinical outcome was favorable after intravenous acyclovir. This case suggests careful monitoring of valacyclovir in HIV-infected patients is necessary.

Abstract
Some HIV-infected patients have a discordant response to highly active antiretroviral therapy with a low virus load and an incomplete restoration of CD4+ T-cell counts. Zidovudine may limit CD4+ restoration by a hematotoxic mechanism. Apoptosis and T-cell counts were assessed in two patients before and after they switched from zidovudine to stavudine. Whereas CD4+ T-cell apoptosis fell from 52% and 66% before the zidovudine switch to 7% and 12%, respectively, after the switch, the patients' CD4+ counts rose gradually to +183 and +150 cells, respectively. It was therefore hypothesized that zidovudine directly induced apoptosis. Zidovudine withdrawal could be tested before immunological interventions such as interleukin-2 therapy are considered.

Abstract
To assess the frequency of shedding of cytomegalovirus (CMV) in saliva, the distribution of CMV glycoprotein B (gB) genotypes, and the occurrence of CMV diseases, we screened 98 human immunodeficiency virus (HIV)-seropositive patients without CMV disease. CMV was detected by culture more frequently in saliva (45 [46%] of 98 patients) than in blood (7 [7.5%] of 93) and was associated with CD4 cell counts <100 cells/mm3 (P=.013). CMV in the saliva of 37 patients was successfully genotyped. Three patients (8%) were infected by a gB1 strain, 26 (70%) by a gB2 strain, 2 (5.5%) by a gB3 strain, 1 (3%) by a gB4 strain, and 5 (13.5%) by mixed gB strains. Thirteen patients developed CMV disease after a mean period of 143+/-112 days; at inclusion, 9 (69%) had salivary CMV shedding and 2 had CMV viremia. CMV salivary shedding (P=.043), low CD4+ cell count (P=.041), and CMV viremia (P=.011) were associated with occurrence of CMV disease.

Abstract
INTRODUCTION Immune restoration syndrome was first described in 1998 and involved mycobacterium avium complex. We report the case of a patient with acquired immunodeficiency syndrome who had disseminated cutaneous lesions due to Mycobacterium tuberculosis, following initiation of highly active antiretroviral therapy. CASE REPORT A 42 year-old HIV-infected man, was admitted for fever, cough, nocturnal sweat and impaired of general condition. He had a viral load of 127,200 copies/ml and 199/ml CD4 T-cells. He was treated with triple tuberculosis combination therapy according to tuberculous contagium, positivity of the tuberculin intradermoreaction (15 mm) and right upper lung nodule on thoracic scan. M. tuberculosis was not found. Fever improved at day 3. Highly active antiretroviral therapy with zidovudine, lamivudine, indinavir, was started at day 11 and 33 days after, fever and dermohypodermal nodules with necrotising evolution appeared. Skin biopsy specimen showed tuberculoid granuloma. The levels of viral load and CD4 T-cells were less than 200 copies/ml and 497/ml respectively. Fever and cutaneous lesions spontaneously resolved without changing therapy. DISCUSSION Immune restoration syndrome appears after initiation of antiretroviral therapy, in patients with advanced HIV infection and without prophylactic treatment versus MAC. This case report probably involves mycobacterium tuberculosis. Bacterial lysis and immune restoration take part in cutaneous pathogenesis. Subclinical mycobacterial infection should be monitored during initiation of antiretroviral therapy in patients with advanced HIV infection.

Abstract
BACKGROUND Restoration of immunocompetence in HIV-infected patients after antiretroviral treatment can have unexpected effects. CASE REPORTS An unusual course of treated tuberculosis was observed in four HIV-infected patients soon after initiation of antiretroviral therapy. These patients developed fever and enlarged necrotic adenopathies despite an efficacious antituberculous therapy. They were in the initial stage of their antituberculous therapy that had been initiated a mean 12 days prior to initiation of antiretroviral therapy. The antiretroviral therapy led to an undetectable HIV load within 2 months. DISCUSSION These unusual features, which also occurred with an increase in CD4 cell counts, could be related to the immunological restoration and to the reappearance of delayed type hypersensitivity. The onset of antiretroviral therapy could thus be delayed by several weeks in HIV-infected patients treated for active tuberculosis and who have never received antiretroviral therapy.

Abstract
OBJECTIVE To determine the specific characteristics of Streptococcus bovis infective endocarditis (IE) by reviewing our own experience of S. bovis IE. METHODS Twenty episodes of definite S. bovis IE were reviewed in 20 patients hospitalized from 1980 to 1996. RESULTS The mean age was 62 +/- 14 years, and 14 (70%) patients had no known predisposing cardiac condition. The principal antimicrobials used were penicillin G (N = 10) and amoxycillin (N = 8). Surgery was required in four (20%) patients. Neurologic complications occurred in eight (40%) patients, after initiation of therapy in six (75%) (mean time: 14 days). An unfavorable outcome was observed in four of 20 patients and tended to be more frequent in patients who had had neurologic complications (P = 0.10). Colonic tumors were present in 11 of 16 (69%) patients. CONCLUSIONS Advanced age, occurrence of IE on presumably normal valves, high rate of neurologic complications, associated gastrointestinal diseases and low mortality rate during initial follow-up are characteristic features of S. bovis IE observed in this study.

Abstract
Haemophagocytic syndrome (HPS) and HIV infection are both associated with cytokine network dysregulation. We therefore analysed plasma levels and mRNA synthesis in peripheral blood mononuclear cells (PBMC) of cytokines, chemokines and chemokine receptors in one HIV-infected patient with HPS. We compared the results with those for eight HIV-infected patients with similar CD4+ T cell counts (207/mm3 versus controls: median 214/mm3) and plasma virus load (4.1 log copies/ml, versus controls: median 4.2 log copies/ml). The HPS patient had a lower viral DNA load in PBMC and higher plasma levels of interferon-gamma, IL-10, and macrophage inflammatory protein (MIP)-1beta. No difference in plasma tumour necrosis factor-alpha (TNF-alpha), IL-6 and MIP-1alpha concentration was observed between the HPS patient and control patients. No difference was observed in TNF-alpha, IL-1beta, IL-10, IL-4, MIP-1alpha, MIP-1beta, RANTES, CXCR-4, and CCR-5 mRNA levels in PBMC, but IL-6 levels were higher in the HPS patient. Our results emphasize the role of IL-10 in the control of immune hyperactivation that is observed in HPS.

Abstract
This prospective multidisciplinary survey started in October 1994. The survey assessed the modalities of care of hospitalized patients with advanced AIDS in an Infectious and Tropical Diseases Unit with regards to the practices of palliative care in a Palliative Care Unit. Seventy-eight (78) AIDS patients with CD4 < or = 30/mm3 who had 102 consecutive hospitalizations were recruited. Types (symptomatic or curative) and number of drugs administered to the patients, as well as biological and radiological investigations performed were recorded. Symptoms were concomitantly assessed on a weekly basis by self-evaluation of the patients themselves and by physicians. The results showed that the practices of care were different in the two units according to the specific goals and norms of each unit. A higher density of care was delivered at the Infectious and Tropical Diseases Unit. Symptoms assessed by both patients and physicians were underestimated by physicians in frequency and in intensity. In conclusion, an integrated approach including objective and subjective criteria should enable a better adjustment of the palliative and curative therapeutic strategies in advanced AIDS. These would concomitantly take into account the wishes of the patient and the goals regarding care in the unit where the patient is hospitalized.

Abstract
OBJECTIVE To describe the spontaneous course, before the introduction of highly active antiretroviral therapy (HAART), of HIV-1 RNA during the AIDS-free period of the disease. To assess the predictive value of changes in HIV-1 RNA levels. DESIGN A total of 330 patients with a known date of infection followed in the SEROCO cohort. METHODS HIV-1 RNA levels (threshold, 200 copies/ml) were evaluated from 2243 frozen sera obtained from enrolment until the onset of AIDS or until February 1996. Lowess curves were used to describe the variations of viraemia during follow-up. A Cox regression model was used to assess the predictive value of early and updated CD4 cell count and viral load. RESULTS In addition to a lower early viral load, patients who remained AIDS-free had, on average, a longer period of viral load decrease after infection (36 versus 18 months), followed by a slower viral load increase compared with those who progressed to AIDS. A true plateau-phase after the seroconversion period, lasting approximately 4 years, was identified only in patients who remained AIDS-free for at least 90 months. In multivariate analysis, both early viral load and later changes were significant predictors of progression to AIDS. A decrease in the CD4 cell count to less than 200 cells/microl and the onset of a group B condition remained significant predictors of progression. CONCLUSION Our study extends to the early post-seroconversion phase the prognostic value of extracellular HIV-1 RNA levels. Moreover, our data suggest that, in most HIV-infected individuals, a progressive loss of control of viral replication arises during the early years of HIV-1 infection.

Abstract
Mycotic pulmonary aneurysm is an infrequently diagnosed complication of endocarditis. We report here a case of mycotic pulmonary aneurysm and a review of 25 cases from the literature. The mortality rate is greater than 50%. Prompt diagnosis is necessary because early intrasaccular embolization and/or surgical repair is essential to avoid death from rupture of the aneurysm.

Abstract
We report the cases of three patients treated for infective endocarditis (IE) for whom corticosteroids were added to the antibiotic treatment. They all had clinical and biological evidence of immune-mediated glomerulonephritis. The microorganisms responsible for IE were Coxiella burnetii, Streptococcus bovis, and Cardiobacterium hominis. Median duration of IE before antimicrobial therapy was 7 months. In all patients, renal function deteriorated despite appropriate antimicrobial treatment for a mean duration of 16 days, but it improved after addition of corticosteroid therapy. All patients were cured of IE. A literature review revealed four additional cases of IE-related glomerulonephritis in which adjunctive immunosuppressive therapy was considered to be effective. Although corticosteroid therapy is generally not recommended for IE, it should be considered for patients whose renal dysfunction secondary to glomerulonephritis does not improve with appropriate antimicrobial treatment, especially if the duration of the illness is long.

Abstract
A randomized open-label phase 2 trial compared the virological and clinical effects on cytomegalovirus (CMV) infection of a 14-day course of intravenous foscarnet (100 mg/[kg x 12 h]) or no treatment in 42 HIV-infected patients with < 100 CD4 cells/mm3 and persistent asymptomatic CMV viremia. All CMV markers (blood culture, pp65 antigenemia, plasma and leukocyte DNA) either became negative or decreased significantly at day 14 in the foscarnet group. CMV blood culture results at day 14 were positive in 14% of those receiving foscarnet versus 60% of control patients (P = .004). However, after the end of treatment, all markers reappeared or the virus load rapidly increased. The probability of CMV disease at 6 months was 43% in both groups. Patients who had or who achieved a negative blood culture at any time had a reduced risk of CMV disease (RR = 2.64; 95% CI = 1.24-5.62; P = .02). This study suggests that sequential courses of intravenous foscarnet might not be a good strategy for preemptive therapy in this population and that in patients with a positive blood marker, treatment able to induce and maintain negative CMV blood cultures could constitute an effective intervention.

Abstract
OBJECTIVE To determine the frequency of Clostridium difficile carriage in HIV-infected in- and out-patients, and to assess the role of this carriage in nosocomial transmission of C. difficile. PATIENTS AND METHODS Prospective study in a university hospital. Forty-five consecutive HIV-infected out-patients and 120 hospitalized patients (52 HIV and 68 non HIV-infected-patients) were studied. During the period of hospitalization, 44 patients (24 HIV and 20 non-HIV-infected patients) with a negative culture within 48 h of admission were followed weekly for fecal carriage. Clostridium difficile culture and latex agglutination were performed on the fecal samples of each patient. In the case of positive culture and/or latex agglutination, C. difficile toxin assays were performed by microtitre cytotoxicity method. RESULTS Out-patients: one patient was a carrier and one patient with diarrhoea was infected with a toxigenic strain (2/45, 4.5%, 95% CI = 1-17). Eighty percent of the HIV-infected out-patients had received antimicrobial agents previously. In-patients: in the first 48 h, five asymptomatic patients were carriers (three non-HIV and two HIV-infected patients). Among 20 patients who complained of diarrhoea, one HIV-infected patient had only a positive latex agglutination and one HIV-infected patient was infected with a toxigenic strain. Overall, 7/120 (5.8%, 95% CI = 2-10) patients were infected or colonized with C. difficile. During the hospitalization (743 patient-days), none of the 44 patients acquired C. difficile. CONCLUSION This study suggests that in this given unit, C. difficile carriage is low, at least with single room accommodation, and in the absence of clusters of cases. This carriage is not different in HIV and non-HIV infected patients despite treatment with multiple antibiotics, and is not different in patients managed in different care environments. The systematic identification of C. difficile carriers for isolation and prophylactic treatment is not useful under these circumstances.

Abstract
Randomized clinical trials analyzed by the intent-to-treat approach provide unbiased comparisons among treatment groups. To avoid dilution of treatment effect, many people also perform an analysis by treatment actually received, although this method may introduce bias into the results. This paper presents several approaches used for analyzing data of a recent trial and the difficulties encountered in interpreting the results of each approach. The ANRS 005/ACTG 154 Study was a double-blind, placebo-controlled, randomized, international (French, U.S., and Spanish) multicenter trial designed to assess the effectiveness of pyrimethamine for the primary prophylaxis of cerebral toxoplasmosis (CT) in HIV-infected patients with advanced immunodeficiency. In the intention-to-treat analysis, the cumulative probability of CT at 1 year did not differ significantly between the pyrimethamine arm (11.9%) and the placebo arm (13.1%), Hazard Ratio (HR) = 0.94 (95% Confidence Interval (CI) = 0.62-1.42), whereas an on-treatment analysis resulted in a significant difference: 4.2% in the pyrimethamine arm and 12.4% in the placebo arm, HR = 0.44 (95% CI = 0.24-0.80). The data showed a significant interaction between compliance and treatment outcome; and side effects were more frequently cited as reasons for compliance violations in the pyrimethamine group. Several different analytic approaches (censoring data at the time patients discontinued the study medication only for selected reasons) failed to explain the disparity between the estimation of effect of pyrimethamine by the intention-to-treat and on-treatment analyses. This experience led us to believe that comparing the results of both analyses was the best method to convince clinicians that intention-to-treat was the only interpretable analysis. We were concerned that even if pyrimethamine had a beneficial effect, it was very difficult (1) to quantify and (2) to apply to clinical practice unless one could predict the occurrence of study drug discontinuation for each patient at the time of treatment assignment. Although exploratory analyses may yield clinically relevant information and useful clarifications in the evaluation of treatments, intention-to-treat remains the only interpretable analysis of clinical trials.

Abstract
We screened 192 patients infected with human immunodeficiency virus (HIV) to examine the relation between CD4+ lymphocyte counts and cytomegalovirus (CMV) viremia and the occurrence of CMV disease and subsequent duration of survival. When we stratified the viremic patients by CD4+ lymphocyte counts, the proportions were as follows: <50/mm3, 20 (25%) of 80 patients; 50-100/mm3, 2 (5.5%) of 36; 101-150/mm3, none of 14; and >150/mm3, 1 (1.5%) of 62. After a mean follow-up period of 8.5 months, 21 (11%) of 192 patients developed CMV disease. The probability of developing CMV disease at 6 months was 13% when the CD4+ lymphocyte count was <50/mm3, 3% when the CD4+ lymphocyte count was 50-100/mm3, and 0 when the CD4+ lymphocyte count was >100/mm3; this probability was 46% for viremic patients and 1% for nonviremic patients. In a multivariate analysis, CMV viremia was independently prognostic of CMV disease (relative risk, 22.03; 95% confidence interval, 6.49-78.97; P < .001), whereas a CD4+ lymphocyte count of <50/mm3 was not (P = .26). These results support the value of CMV viremia for predicting which HIV-infected patients are at risk of developing CMV disease and should therefore receive primary prophylaxis.

Abstract
The objective of this study was to assess whether patients with CD4+ cell counts <200 x 10(6)/L have a decreased survival after the occurrence of any AIDS-defining event; 187 patients from the placebo arm of a clinical trial of toxoplasmosis prophylaxis (ANRS005-ACTG154) were included. For this analysis, patients were HIV infected without any AIDS-defining event, had a CD4+ lymphocyte count < 200 x 10(6)/L, had a positive serology for Toxoplasma gondii, and had no severe liver, renal, or hematologic abnormalities. We used proportional hazards regression to study the relationships between baseline variables. AIDS-defining events as time-dependent variables, and survival. The risk of dying was increased by 1.9 for a 10-year increase in age and by 1.3 when CD4+ decreased by 50 x 10(6)/L; after the occurrence of a pneumocystosis, a cytomegalovirus infection, or a toxoplasmosis, the risk of dying was multiplied, respectively, by 10.9 (3.0-40.2), 10.0 (2.8-35.4), and 10.0 (4.5-22.2). None of the other AIDS-defining events was associated with an increased risk of dying, but the power to detect such an association was limited. We conclude that the occurrence of pneumocystosis, cytomegalovirus infection, or toxoplasmosis; age; and CD4+ cell count are important determinants of survival for HIV1-infected patients with CD4+ counts < 200 x 10(6)/L who are toxoplasmosis antibody positive.

Abstract
In randomized placebo-controlled trials in Haïti, Zambia and Uganda, prophylactic use of isoniazid (INH) for 6 to 12 months reduced the annual incidence of tuberculosis in HIV-infected patients by more than 50 per cent. For several years, WHO, IUTATLD and CDC have recommended that HIV-positive patients testing positive in a PPD test should be treated with INH as a form of anti-tuberculosis chemoprophylaxis (ATC). Whilst these recommendations are easy to follow in industrialized countries, widespread use of ATC in developing countries remains problematic because: (i) It is unknown what proportion of patients are likely to be re-infected at the end of ATC in countries where TB is endemic; (ii) It is possible that resistant bacilli may be selected due to the incomplete exclusion from the ATC program of patients with active TB at enrollment; (iii) It is difficult to identify asymptomatic carriers of M. tuberculosis at enrollment; (iv) It is doubtful that all patients will comply with a treatment regime which lasts several months; (v) The cost of a widespread ATC program, whose full benefit remains to be evaluated, may be difficult to justify. This paper attempts to review these issues and demonstrates the need for more population-based clinical trials in the field.

Abstract
Although drug-induced rash is frequent in human immunodeficiency virus (HIV)-infected patients, rash due to pyrimethamine has not been described previously. In a randomized, double-blind, placebo-controlled study of pyrimethamine as primary prophylaxis for toxoplasmic encephalitis, the incidence of rash (per hundred patient-years) was 8.1 in the pyrimethamine group versus 1.5 in the placebo group (P < .0002). The 1-year incidence of toxoplasmic encephalitis after occurrence of rash was 37%, as compared with 9.6% in the pyrimethamine group without rash, with a 3.7 times higher risk for patients with pyrimethamine-induced rash (P = .001); the incidence was 13% in the placebo group. At the time of toxoplasmic encephalitis, pyrimethamine was successfully readministered to 80% of patients who discontinued it because of rash. Thus, pyrimethamine, when used for prophylaxis, does induce rash in HIV-infected patients. These patients are at higher risk for toxoplasmic encephalitis and should be carefully monitored for it.

Abstract
OBJECTIVE To study the predictive value of anti-Toxoplasma gondii antibody titres for the occurrence of toxoplasmic encephalitis (TE) in HIV-infected patients. METHODS Data from the placebo arm of a trial of primary prophylaxis for TE (ANRS 005/ACTG 154) were analysed. Patients included had CD4+ cell counts < 200 x 10(6)/l and a positive Toxoplasma serology. Immunoglobulin (Ig) G and IgM Toxoplasma antibody titres at entry were retrospectively determined by enzyme-linked immunosorbent assay and agglutination on serum samples in a single laboratory. Incidence of TE was estimated by Kaplan-Meier method and a Cox model was used to study the predictive value of antibody titres, adjusted for other covariates. RESULTS All 164 patients studied were positive for IgG antibodies and one had IgM antibodies. After a mean follow-up of 16 months, 31 cases of TE were documented. One-year incidence of TE was significantly higher in patients with IgG titres > or = 150 IU/ml (23.7%) than in patients with titres < 150 IU/ml (7.7%; relative risk, 3.1; P < 0.003). IgG titres remained significantly associated with the occurrence of TE (relative risk, 3.3; P < 0.005) in the Cox model. Predictive value of IgG titres did not differ according to baseline CD4+ cell counts. CONCLUSIONS In patients with CD4+ cell counts < 200 x 10(6)/l, IgG anti-Toxoplasma antibody titre is a prognostic factor of occurrence of TE, with a higher risk for titres > or = 150 IU/ml. This finding should reinforce the recommendation of specific prophylaxis in these patients.

Abstract
Toxoplasmosis can be a severe infection in immunosuppressed patients. In these patients it can present as collected encephalitis, diffuse hypoxemic pneumopathy, or disseminated infection with fatal outcome. These presentations are observed mainly in HIV-infected patients, and less frequently in bone-marrow transplanted, or heart or heart and lung transplanted patients, or in patients given long term steroids or immunosuppressive therapy. The disease is due most often to the reactivation of latent persistent forms of the parasite at a moment of depression of host defense mechanisms, with local reactivation, and/or hematogenous dissemination. In some cases, the disease is favored by an insufficient protective response after primary infection. Treatment, based on the pyrimethamine-sulfadiazine combination should be continued as long as a profound immunosuppression is present. Prevention is based on recommendations to avoid acquisition of the parasite for seronegative patients, and on chemoprophylaxis, using cotrimoxazole as first line regimen, in patients already infected with Toxoplasma gondii.

Abstract
Pyrimethamine (50 mg) with folinic acid (15 mg) given three times weekly was assessed as primary prophylaxis for toxoplasmic encephalitis (TE) in 554 human immunodeficiency virus-infected patients seropositive for Toxoplasma gondii and with < 200 CD4 cells/mm3. At 1 year, the incidence of TE was similar in pyrimethamine, 12%, and placebo, 13%, groups (relative risk [RR], 0.9; 95% confidence interval [CI], 0.6-1.4), and the survival rate was also similar, 85% and 80%, respectively (RR, 0.9; 95% CI, 0.7-1.2). Rash was the only adverse event that appeared significantly more frequently in the pyrimethamine arm (7% vs. 1%). In the on-treatment analysis, the incidence of TE was lower in the pyrimethamine arm, 4%, than in the placebo arm, 12% (P < .006). Thus, pyrimethamine cannot be recommended as a first-line regimen for primary prophylaxis of TE if the patient can take cotrimoxazole. However, it should be considered for patients who are intolerant to cotrimoxazole, especially in high-risk patients with < 100 CD4 cells/mm3.

Abstract
OBJECTIVE To investigate whether HIV-1 infection acquired through a severely immunodepressed sexual partner increases the risk of disease progression. DESIGN A prospective cohort of patients infected through sexual contact at a known date and enrolled a few months (median, 2 months) after their first HIV-positive test. At enrolment, 12 subjects stated having had unprotected intercourse (anal or vaginal penetration) with a partner with AIDS within the 6 months prior to their first HIV-positive test. For the same period, 60 subjects stated having had unprotected intercourse with a partner, known to be HIV-positive, but who had not developed AIDS. METHOD The endpoint was the first occurrence of an HIV-related illness (group IV or AIDS, 1987 Centers for Disease Control and Prevention revised classification). Event-free survival curves since infection were constructed using the Kaplan-Meier method and compared by the log-rank test. The Cox model was used for multivariate analysis. RESULTS Disease progression was more rapid among the 12 subjects who stated having sex with a person with AIDS at a time close to infection, than among the other subjects (P = 0.03). Homosexuality and age at infection were also related to HIV disease progression. The adjusted relative risk of developing an HIV-related illness among those 12 subjects was 3.9 (95% confidence interval, 1.5-9.9). CONCLUSION Our results confirm the influence of virus-related factors on the onset of immunodepression in subjects infected through sexual contact.

Abstract
A randomized, unblinded study compared aerosolized pentamidine, 300 mg every month, and dapsone, 50 mg/day, for secondary prophylaxis of pneumocystosis in 196 AIDS patients. The study was prematurely discontinued due to excess mortality in the dapsone group. After a mean follow-up of 13 +/- 6.4 months, 22 (21%) of 103 patients in the pentamidine group were dead compared with 39 (42%) of 93 receiving dapsone; the estimated mortality rates at 18 months were 24.6% and 53.1%, respectively (P < .003, log-rank test). A negative interaction was observed between zidovudine and dapsone (P < .049, interaction test of Cox model), and the mean CD4 cell count during the study was lower in the dapsone (49 +/- 61/mm3) than in the pentamidine group (83 +/- 88/mm3; P < .002, t test). The lower survival might also be related to the oxidative effect of dapsone or to the addition of iron protoxalate to dapsone in this study. These results suggest caution in using dapsone as long-term therapy in advanced human immunodeficiency virus infection, especially in those receiving zidovudine.

Abstract
OBJECTIVES Determine the clinical features and outcome of acute pneumonia due to Streptococcus pneumoniae in HIV infected patients compared with non-HIV infected patients. METHODS From January 1986 to February 1992, we observed 33 episodes of pneumococcal pneumonia in 27 HIV-infected patients. Most of the patients were drug addicts (16/27), and/or originated from Central Africa or Haiti (10/27). In 9/27 (33%) patients, HIV infection was previously unknown. Eleven of the 27 patients were at the CDC stages II-III and CD4 cell count was greater than 200/mm3 and CD8 cell count was greater than 1000/mm3 in 12/23 patients and 10/20 patients respectively. RESULTS In 10/33 episodes, respiratory symptoms were severe: bilateral pneumonia (n = 2) and/or hypoxaemia (n = 9). In 22/33 episodes, hospitalization occurred less than 24 h after the onset of symptoms and in 9/33 episodes, the initial chest X-ray was normal. Streptococcus pneumoniae was isolated in 16/33 episodes, from blood (n = 10), bronchoalveolar lavage (n = 3) or sputum (n = 3). Penicillin G or amoxicillin was used and allowed a favorable and quick response in all episodes. Recurrence occurred in 5/18 (27%) followed patients. These recurrences were not favoured by a low CD4 cell count since it was more than 200/mm3 in these five patients. However, the mean count of CD8 cells was higher in patients with recurrence than in patients without recurrence, 1990/mm3 versus 995/mm3 (p = 0.03). CONCLUSION CD8 hyperlymphocytosis could increase the risk of recurrence and would help identify a subgroup with higher risk of pneumococcal pneumonia among HIV infected persons.

Abstract
The activity of roxithromycin against three clinical isolates of Mycobacterium avium was compared with that of clarithromycin both in a model of infection of human monocyte-derived macrophages and in a model of established infection of C57BL/6 mice. In the cell culture model, roxithromycin and clarithromycin were bactericidal for strains MO-1 and N-92159 and bacteriostatic for strain N-93043. For the three strains, the differences between the intracellular activities of roxithromycin and clarithromycin were not singificant after 7 days of treatment. Mice were infected with the MO-1 strain. Drugs were given by gavage at a dosage of 200 mg/kg of body weight 6 days per week for 16 weeks starting 5 weeks after infection. At the end of treatment, clarithromycin was more effective than roxithromycin in lungs; roxithromycin was as effective as clarithromycin in spleens. Thus, the activity of roxithromycin was comparable to that of clarithromycin both in vitro and in vivo.

Abstract
Bacterial spondylodiskitis--i.e., adjacent vertebral osteomyelitis and diskitis--was studied in 80 adult patients. The infection was due to Mycobacterium tuberculosis in 31 cases (39%) and to pyogenic bacteria in 49 cases (61%). The latter pathogens included gram-negative bacilli in 16 cases (20%), Staphylococcus species in 15 (19%), Streptococcus species in 9 (11%), and Corynebacterium species in 1 (1%); the pathogens in the 8 remaining cases (10%) were not identified. Of the patients with tuberculous spondylodiskitis, 55% came from countries where tuberculosis is endemic (P < .001). Cases due to staphylococci and those due to M. tuberculosis were associated with a high frequency of previous active infection with those respective organisms at any site (47% and 42%, respectively; P < .001) and with a high rate of neurological complications (33% and 32%, respectively; P < .001). Nine patients with pyogenic spondylodiskitis (18%) but only one patient with tuberculous spondylodiskitis (3%) had diabetes mellitus (P < .05). Blood cultures were positive in 23 (56%) of the 41 cases of pyogenic spondylodiskitis due to an identified bacterium. Discovertebral needle biopsy contributed to the bacteriologic diagnosis in 29 (74%) of 39 cases.

Abstract
SETTING Tuberculosis may be diagnosed too late, especially in HIV-infected patients, with consequences on bacillus transmission and survival. Empiric antibuberculosis treatment (EATT) may be started before diagnosis of tuberculosis is confirmed. As rifampicin is a broad spectrum antibiotic, EATT including rifampicin may be effective in infections other than tuberculosis, leading to misdiagnosis. OBJECTIVE To define the efficiency criteria of EATT with or without rifampicin. DESIGN Between 1988 and 1991, 20 febrile patients with suspected tuberculosis (including 15 who were HIV-positive) were started on EATT in the absence of bacteriological or histological proof of tuberculosis. 10 patients (50%) received a 4-drug non-specific EATT including rifampicin, isoniazid, pyrazinamide and ethambutol, and 10 (50%), received a 3-drug specific EATT without rifampicin. RESULTS In 10 patients (50%), the diagnosis of tuberculosis was confirmed by positive cultures within a mean of 32 days (15-57 days) after the beginning of EATT (group TB 1). Of the 10 patients whose cultures remained negative, 4 (20%) became afebrile and showed improvement under EATT (group TB 2), and 6 (30%) remained febrile and did not improve (group No TB). Patients from groups TB 1 and TB 2 became afebrile within a mean of 11 days (1-54 days). This delay was not different between patients receiving specific or non-specific EATT. In patients receiving specific EATT, rifampicin was added to the initial 3-drug treatment after resolution of fever. CONCLUSION EATT appears to be a useful method for rapid presumptive diagnosis and treatment of tuberculosis.

Abstract
OBJECTIVES A prospective multicentric epidemiological study (SEROCO) of subjects with a diagnosis of human immunodeficiency virus (HIV) infection was started on January 1, 1988 in order to better understand the natural history of HIV infection and factors related to outcome. Observations after 4 years of follow-up are reported here. METHODS After authorization by the French national ethics committee and the national commission for personal freedom, 18 French centres included non-haemophiliac volunteers who were asymptomatic, had had non anti-HIV treatment and whose HIV positivity had been known less than 1 year at inclusion. These last three criteria were not required for patients whose precise date of contamination was known within a range of +/- 3 months. RESULTS On July 15, 1992, there were 1453 infected subjects in the cohort (1063 males, 417 females; age range at inclusion 18-75 years; mean age 31.3 +/- 9.4). Globally, 2.7% of the subjects were symptomatic at inclusion. Mean CD4 lymphocyte count at inclusion was 508/mm3. Clinically, 51.5% of the patients had a history of sexually transmitted disease at inclusion. After 4 years (on July 15, 1992) mean follow-up was 28 +/- 12.9 months for a total of 3428 patient-years. Disease progression to stage IV was observed in 439 patients including 202 who developed the acquired immuno-deficiency syndrome (AIDS). Among these 202 patients, 113 had died at the end-point of this report. The first manifestation of AIDS was Kaposi sarcoma in 44, pulmonary pneumocystosis in 38 and cerebral toxoplasmosis in 27. The probability of developing AIDS was calculated at 13.9% at 5 years, 27.7% at 7 years and 33.7% at 10 years. The probability of a CD4 count below 200/mm3 was 32.7, 55.6 and 67% at 5, 7 and 10 years respectively. For patients with a CD4 count below 200, the probability of developing AIDS was 18% at 1 year, 39% at 2 years and 51% at 3 years. CONCLUSIONS SEROCO has been a most useful prospective epidemiological tool due to the diversity of the subjects included. The observed natural history of HIV infection will lead to specific research projects aimed at better understanding the disease process.

Abstract
SETTING Chloroquine, an alkalinizing lysosomotropic agent, enhances the intracellular activity of antibiotics against Mycobacterium tuberculosis or Coxiella burnetii. OBJECTIVE To determine if chloroquine modifies the activity of clarithromycin, less effective at acidic pH, against intracellular Mycobacterium avium. DESIGN The activity of clarithromycin (4 micrograms/ml) against the MO-1 strain of M. avium was evaluated within human macrophages in presence of chloroquine (5 micrograms/ml). The minimal inhibitory concentration of clarithromycin for the strain was 2 micrograms/ml. RESULTS While clarithromycin alone did decrease the intracellular infection at day 7 of culture (P < 0.01), chloroquine alone did not impede the intracellular growth of M. avium, and did not enhance the activity of clarithromycin. CONCLUSION Chloroquine should not improve clarithromycin treatment against M. avium infection.

Abstract
OBJECTIVE To determine criteria for the diagnosis of cytomegalovirus (CMV) colitis and to analyse stages of the course and prognosis of CMV colonic involvement in HIV-1-infected patients. DESIGN Prospective search for CMV colonic involvement with systematic biopsies to search for CMV intranuclear inclusion bodies and for CMV culture. The evolution of CMV colonic involvement was estimated using further coloscopies and autopsy. SETTING Infectious diseases department in a tertiary referral teaching hospital in Paris, France. PARTICIPANTS Fifty-five consecutive patients with HIV-1 infection, who had not previously received anti-CMV drugs, and who had at least one coloscopy performed. RESULTS According to initial coloscopy, colitis, either ulcerative or inflammatory, was found in nine (16%) out of the 55 patients, CMV intranuclear inclusions were present in the colon of four (7%) patients, and colonic cultures were positive for CMV in 15 (27%) patients. The results of the initial coloscopy showed a positive correlation between endoscopic colitis (either ulcerative or inflammatory), CMV inclusions and positive CMV culture from colonic biopsies. The absence of endoscopic ulcerative lesions had a 98% (49 out of 50) negative predictive value for recording CMV inclusions in the colon (95% confidence interval, 89-100). CMV inclusions were recorded in three out of five ulcerative colitis. Male homosexuality, HIV-1 infection stages IVB, C1, D or E, according to the Centers for Disease Control and Prevention classification, CD4 lymphocyte count < 200 x 10(6)/l and CMV viraemia also correlated positively with CMV colonic involvement. During the observation period (mean, 7.3 months), the estimated incidence of CMV colitis according to coloscopic studies was 13%. Deterioration in condition was the most frequent spontaneous evolution of CMV colonic infection, whereas anti-CMV treatment resulted in an improvement. Ulcerative lesions occurred earlier in patients with colonic CMV inclusions or positive colonic CMV culture than in patients without CMV colonic involvement at the initial coloscopy. CMV colitis occurred late in the course of HIV-1 infection, on average 4 months before death. The presence of CMV inclusions was an indicator of poor prognosis with earlier occurrence of CMV viraemia and retinitis and no survival after 9 months. CONCLUSIONS These results confirm that the colon is a target organ for CMV in HIV-1-infected patients. Coloscopy should be used to diagnose CMV colitis, because of the close correlation between endoscopic and histological data (i.e., intranuclear inclusions). This combination allows us to propose an evolutive staging of CMV colonic involvement and provide stratification criteria to assess the efficacy of anti-CMV drugs.

Abstract
The case of an immunocompetent woman who died of disseminated cytomegalovirus infection with encephalitis and skin ulcerations is reported. The duration of the disease, from onset to death, was five months. Cytomegalovirus was found in the blood, urine, skin, muscle, liver and periventricular brain tissue, but not in frontal cortex tissue. This case underlines the fact that cytomegalovirus may exceptionally cause life-threatening illness in immunocompetent adults.

Abstract
We report two cases of penicillin G-resistant pneumococcal meningitis in adults, with clinical and bacteriological failure of amoxicillin and negative or incomplete response to third generation cephalosporins. Meningitis occurred in a man treated for myeloma and in an elderly woman under prolonged intermittent amoxicillin therapy for chronic otitis. Such situations are known as exposing to pneumococcal meningitis and to resistance of the strain involved to penicillin G. Both patients were cured by vancomycin in continuous infusion associated with rifampicin or fosfomycin. Contrary to third generation cephalosporins, which have higher minimal inhibitory concentrations, vancomycin and rifampicin are still fully active against penicillin G-resistant pneumococcal strains. Thus, vancomycin administered in continuous infusion and associated with rifampicin and fosfomycin deserves to be tried as first-line treatment of pneumococcal meningitis in patients at risk of resistance to penicillin G.

Abstract
A prospective study was conducted to evaluate azithromycin in combination with pyrimethamine for treatment of acute Toxoplasma encephalitis in patients with AIDS. Of the 14 patients given 75 mg pyrimethamine and 500 mg azithromycin daily for four weeks, eight were evaluable for clinical response. Five responded favorably, one had an intermediate response and two an unfavorable response. Of the nine patients evaluable for radiological response, six responded favorably, and three had an intermediate response. Eleven adverse events occurred in nine patients: rash (n = 5), abnormal liver function (n = 2), vomiting (n = 3) and hypoacousia (n = 1). This pilot study suggests that the combination of pyrimethamine and azithromycin may be further investigated and that the optimal dosage of azithromycin has yet to be determined.
