RESUMEN

In this placebo-controlled phase II randomized clinical trial, 103 human immunodeficiency virus type 1 (HIV-1)-infected patients under cART (combined antiretroviral treatment) were randomized 2:1 to receive either 3 doses of DNA GTU-MultiHIV B (coding for Rev, Nef, Tat, Gag, and gp160) at week 0 (W0), W4, and W12, followed by 2 doses of LIPO-5 vaccine containing long peptides from Gag, Pol, and Nef at W20 and W24, or placebo. Analytical treatment interruption (ATI) was performed between W36 to W48. At W28, vaccinees experienced an increase in functional CD4+ T-cell responses (P < 0.001 for each cytokine compared to W0) measured, predominantly against Gag and Pol/Env, and an increase in HIV-specific CD8+ T cells producing interleukin 2 (IL-2) and tumor necrosis factor alpha (TNF-α) (P = 0.001 and 0.013, respectively), predominantly against Pol/Env and Nef. However, analysis of T-cell subsets by mass cytometry in a subpopulation showed an increase in the W28/W0 ratio for memory CD8+ T cells coexpressing exhaustion and senescence markers such as PD-1/TIGIT (P = 0.004) and CD27/CD57 (P = 0.044) in vaccinees compared to the placebo group. During ATI, all patients experienced viral rebound, with the maximum observed HIV RNA level at W42 (median, 4.63 log10 copies [cp]/ml; interquartile range [IQR], 4.00 to 5.09), without any difference between arms. No patient resumed cART for CD4 cell count drop. Globally, the vaccine strategy was safe. However, a secondary HIV transmission during ATI was observed. These data show that the prime-boost combination of DNA and LIPO-5 vaccines elicited broad and polyfunctional T cells. The contrast between the quality of immune responses and the lack of potent viral control underscores the need for combined immunomodulatory strategies. (This study has been registered at ClinicalTrials.gov under registration no. NCT01492985.)IMPORTANCE In this placebo-controlled phase II randomized clinical trial, we evaluated the safety and immunogenicity of a therapeutic prime-boost vaccine strategy using a recombinant DNA vaccine (GTU-MultiHIV B clade) followed by a boost vaccination with a lipopeptide vaccine (HIV-LIPO-5) in HIV-infected patients on combined antiretroviral therapy. We show here that this prime-boost strategy is well tolerated, consistently with previous studies in HIV-1-infected individuals and healthy volunteers who received each vaccine component individually. Compared to the placebo group, vaccinees elicited strong and polyfunctional HIV-specific CD4+ and CD8+ T-cell responses. However, these immune responses presented some qualitative defects and were not able to control viremia following antiretroviral treatment interruption, as no difference in HIV viral rebound was observed in the vaccine and placebo groups. Several lessons were learned from these results, pointing out the urgent need to combine vaccine strategies with other immune-based interventions.

RESUMEN

OBJECTIVES: Studies evaluating the efficacy and safety of the fixed-dose combination ledipasvir (LDV)/sofosbuvir (SOF) in patients coinfected with HIV-1 and hepatitis C virus (HCV) have mainly included treatment-naïve patients without cirrhosis. We aimed to evaluate the efficacy and safety of this combination in treatment-experienced patients with and without cirrhosis. METHODS: We conducted a multicentre, open-label, double-arm, nonrandomized study in patients coinfected with HIV-1 and HCV genotype 1 with and without cirrhosis, who had good viral suppression on their antiretroviral regimens. All patients were pretreated with a first-generation NS3/4A protease inhibitor (PI) plus pegylated interferon/ribavirin. Patients received a fixed-dose combination of LDV/SOF for 12 weeks, or for 24 weeks if cirrhosis was present. The primary endpoint was a sustained virological response (SVR) 12 weeks after the end of therapy. Secondary endpoints included safety, pharmacokinetics and patient-reported outcomes. RESULTS: Of the 68 patients enrolled, 39.7% had cirrhosis. Sixty-five patients [95.6%; 95% confidence interval (CI): 87.6-99.1%; P < 0.0001] achieved an SVR, with similar rates of SVR in those with and without cirrhosis. Tolerance was satisfactory, with mainly grade 1 or 2 adverse events. Among patient-reported outcomes, only fatigue significantly decreased at the end of treatment compared with baseline [odds ratio (OR): 0.36; 95% CI: 0.14-0.96; P = 0.04]. Mean tenofovir area under the plasma concentration-time curve (AUC) at week 4 was high, with mean ± SD AUC variation between baseline and week 4 higher in cirrhotic than in noncirrhotic patients (3261.57 ± 1920.47 ng/mL vs. 1576.15 ± 911.97 ng/mL, respectively; P = 0.03). Mild proteinuria (54.4%), hypophosphataemia (50.0%), blood bicarbonate decrease (29.4%) and hypokalaemia (13.2%) were reported. The serum creatinine level was not modified. CONCLUSIONS: LDV/SOF provided a high SVR rate in PI-experienced subjects coinfected with HCV genotype 1 and HIV-1, including patients with cirrhosis.

RESUMEN

OBJECTIVES: Single nucleotide polymorphisms in the cytochrome P450 (CYP) 2B6 gene have been associated with high interindividual variation in efavirenz pharmacokinetics. However, clinical data on the relationship of CYP2B6 polymorphisms with the occurrence of efavirenz-induced central nervous system (CNS) symptoms are limited. METHODS: We analysed four polymorphisms in the CYP2B6 (516 G>T), CYP3A5 (6986 A>G) and ATP-binding cassette, sub-family B, member 1 (ABCB1) (2677 G>T/A and 3435 C>T) genes in HIV-infected adults virologically suppressed on a protease inhibitor-based regimen who switched to a regimen containing emtricitabine, didanosine and efavirenz in the setting of the ANRS ALIZE trial. Kaplan-Meier methods and Cox regression analysis were used to investigate their association with efavirenz plasma levels and CNS events up to 48 months after switching. RESULTS: In total, 191 patients with a median age of 41 years, who were 87% male and 85% Caucasian, were enrolled in the study. Variant allelic frequencies were 0.49, 0.93, 0.59 and 0.63 for CYP2B6 516, CYP3A5 392, ABCB1 2677 and ABCB1 3435, respectively. The median efavirenz plasma concentration (MEPC) was 2.2 mg/L [interquartile range (IQR) 1.7-2.8 mg/L] and was significantly higher in patients with the deficient CYP2B6 516T. Overall, 242 CNS events were reported in 104 individuals (54%). No correlation was found between MEPC and CNS events. The occurrence of a first CNS event was lower in patients with the CYP2B6 516 G/G genotype vs. CYP2B6 516 T genotypes [50% (IQR: 40-60%) vs. 66% (IQR: 56-75%), respectively; P = 0.02]. In an adjusted Cox regression model, there was a tendency towards a higher risk of a first CNS event among carriers of the variant CYP2B6 516 T allele (relative risk 1.4 [95% CI, 0.99-2.1]; P?=?.06), compared with noncarriers. CONCLUSIONS: The deficient CYP2B6 516 T allele is associated with higher efavirenz plasma drug levels and more frequent CNS-related symptoms.

RESUMEN

OBJECTIVES: The aim of this work was to provide a reference for the CD4 T-cell count response in the early months after the initiation of combination antiretroviral therapy (cART) in HIV-1-infected patients. METHODS: All patients in the Collaboration of Observational HIV Epidemiological Research Europe (COHERE) cohort who were aged ≥ 18 years and started cART for the first time between 1 January 2005 and 1 January 2010 and who had at least one available measurement of CD4 count and a viral load ≤ 50 HIV-1 RNA copies/mL at 6 months (± 3 months) after cART initiation were included in the study. Unadjusted and adjusted references curves and predictions were obtained using quantile regressions. RESULTS: A total of 28 992 patients were included in the study. The median CD4 T-cell count at treatment initiation was 249 [interquartile range (IQR) 150, 336] cells/µL. The median observed CD4 counts at 6, 9 and 12 months were 382 (IQR 256, 515), 402 (IQR 274, 543) and 420 (IQR 293, 565) cells/µL. The two main factors explaining the variation of CD4 count at 6 months were AIDS stage and CD4 count at cART initiation. A CD4 count increase of ≥ 100 cells/mL is generally required in order that patients stay 'on track' (i.e. with a CD4 count at the same percentile as when they started), with slightly higher gains required for those starting with CD4 counts in the higher percentiles. Individual predictions adjusted for factors influencing CD4 count were more precise. CONCLUSIONS: Reference curves aid the evaluation of the immune response early after antiretroviral therapy initiation that leads to viral control.

RESUMEN

BACKGROUND: Interstitial lung disease, cutaneous rash and elevated serum angiotensin converting enzyme (ACE) may suggest diagnoses other than sarcoidosis. PATIENTS AND METHODS: A 58-year-old man had presented dyspnoea for 2 years with increased angiotensin-converting enzyme, as well as an interstitial syndrome and micronodules. The possibility of sarcoidosis was raised. Systemic corticosteroids resulted in improvement of the dyspnoea although it recurred on dose reduction. We noted fluctuating eczematous macules of the limbs with a histology of aspecific folliculitis. The identification of Mycobacterium avium complex (MAC) in the bronchoalveolar wash prompted us to initiate antimycobacterial therapy, but this was to no avail. Review of the CT-scan and questioning of the patient (daily use of a Jacuzzi for 7 years) resulted in diagnosis of hypersensitivity pneumonitis due to MAC. The cutaneous lesions were taken to indicate "hot tub folliculitis". Discontinuation of hot-tub use and a short course of oral corticosteroids resulted in healing within 4 months, with no recurrence at 2 years. DISCUSSION: HTL is a form of hypersensitivity pneumonitis due to the presence of MAC in the water of Jacuzzis. This condition regresses spontaneously without treatment on discontinuation of Jacuzzi use. Hot-tub folliculitis due to Pseudomonas aeruginosa (PA) presents as macules and papules on covered skin areas (swimsuit) within 48hours of bathing and often declines within 2 weeks. CONCLUSION: Our case is original as regards the concomitant lung and cutaneous involvement associated with Jacuzzi use, with an immunoallergic mechanism for the MAC and probably an infectious mechanism for the PA.

RESUMEN

OBJECTIVES: The objective of this nested study was to assess the prevalence of psychiatric disorders in a sample of HIV/hepatitis C virus (HCV)-coinfected patients according to their HCV status. METHODS: The nested cross-sectional study, untitled HEPAVIH-Psy survey, was performed in a subset of HIV/HCV-coinfected patients enrolled in the French Agence Nationale de Recherche sur le SIDA et les Hépatites Virales (ANRS) CO13 HEPAVIH cohort. Psychiatric disorders were screened for using the Mini International Neuropsychiatric Interview (MINI 5.0.0). RESULTS: Among the 286 patients enrolled in the study, 68 (24%) had never received HCV treatment, 87 (30%) were treatment nonresponders, 44 (15%) were currently being treated and 87 (30%) had a sustained virological response (SVR). Of the 286 patients enrolled, 121 patients (42%) screened positive for a psychiatric disorder other than suicidality and alcohol/drug abuse/dependence, 40 (14%) screened positive for alcohol abuse/dependence, 50 (18%) screened positive for drug abuse/dependence, 50 (17.5%) were receiving an antidepressant treatment and 69 (24%) were receiving an anxiolytic. Patients with an SVR did not significantly differ from the other groups in terms of psychiatric disorders. Patients receiving HCV treatment screened positive less often for an anxiety disorder. The highest rate of drug dependence/abuse was among HCV treatment-naïve patients. CONCLUSIONS: Psychiatric disorders were frequent in HIV/HCV-coinfected patients and their rates were comparable between groups, even for patients achieving an SVR. Our results emphasize the need for continuous assessment and care of coinfected patients, even after HCV clearance. Drug addiction remains an obstacle to access to HCV treatment. Despite the recent advent and continued development of directly acting antiviral agents (DAAs), it is still crucial to offer screening and comprehensive care for psychiatric and addictive disorders.

RESUMEN

OBJECTIVES: The aim of this study was to describe the proportion of liver-related diseases (LRDs) as a cause of death in HIV-infected patients in France and to compare the results with data from our five previous surveys. METHODS: In 2010, 24 clinical wards prospectively recorded all deaths occurring in around 26 000 HIV-infected patients who were regularly followed up. Results were compared with those of previous cross-sectional surveys conducted since 1995 using the same design. RESULTS: Among 230 reported deaths, 46 (20%) were related to AIDS and 30 (13%) to chronic liver diseases. Eighty per cent of patients who died from LRDs had chronic hepatitis C, 16.7% of them being coinfected with hepatitis B virus (HBV). Among patients who died from an LRD, excessive alcohol consumption was reported in 41%. At death, 80% of patients had undetectable HIV viral load and the median CD4 cell count was 349 cells/µL. The proportion of deaths and the mortality rate attributable to LRDs significantly increased between 1995 and 2005 from 1.5% to 16.7% and from 1.2‰ to 2.0‰, respectively, whereas they tended to decrease in 2010 to 13% and 1.1‰, respectively. Among liver-related causes of death, the proportion represented by hepatocellular carcinoma (HCC) dramatically increased from 5% in 1995 to 40% in 2010 (p = 0.019). CONCLUSIONS: The proportion of LRDs among causes of death in HIV-infected patients seems recently to have reached a plateau after a rapid increase during the decade 1995-2005. LRDs remain a leading cause of death in this population, mainly as a result of hepatitis C virus (HCV) coinfection, HCC representing almost half of liver-related causes of death.

RESUMEN

Internal medicine is a medical specialty that is often poorly understood by the general public and sometimes misidentified. In an era of increasing subspecialization and high technicality, it is characterized by a comprehensive approach centered on clinical evaluation. Unlike what is observed in most developed countries, where systemic autoimmune diseases are managed by organ specialists based on their mode of presentation, French internists are at the forefront for diagnosing and managing these diseases. Their multidisciplinary training gives them legitimacy to justify this role. Internists also play a crucial role in the management of patients requiring unplanned hospitalizations downstream from emergency departments and in connection with primary care. Internists primarily practice in a hospital setting, with a specific position in the French healthcare system aligned with the training frameworks of all medical specialties. To better define internal medicine, its role in care activities, as well as in education and research, internists organized a General Assembly of internal medicine that took place on September 28, 2023, in Paris. Structured around think tanks focusing on care, education, and research activities, the general assembly aimed to improve visibility on internal medicine and internists. This article recounts the discussions that animated this meeting and highlights the main ideas that emerged. These general assemblies constitute a foundational step and will be followed by a Consultation Conference in order to better identify and promote internal medicine and internists, regardless of their types and places of practice.

RESUMEN

OBJECTIVES: Many HIV-infected patients with chronic hepatitis C virus (HCV) infection do not receive treatment for HCV infection, often because of contraindications or poor adherence to anti-HIV therapy. The aim of this study was to identify factors influencing guideline-based HCV treatment initiation in a large cohort of HIV/HCV-coinfected patients. METHODS: Between 2005 and 2011, 194 (40.5%) of 479 coinfected patients not previously treated for HCV infection started this treatment based on current recommendations, i.e. a Metavir score >F1 for liver fibrosis; HCV genotype 2 or 3 infection; or HCV genotype 1 or 4 infection and low HCV viral load (<800000 IU/mL), whatever the fibrosis score. Clinical and biological data were compared between patients who started HCV therapy during follow-up and those who did not. RESULTS: In multivariate analyses, good adherence to treatment for HIV infection, as judged by the patient's physician, was associated with HCV treatment initiation [odds ratio (OR) 2.37; 95% confidence interval (CI) 1.17-4.81; P=0.017], whereas patients with children (OR 0.53; 95% CI 0.30-0.91; P=0.022) and those with cardiovascular disease or respiratory distress (OR 0.10; 95% CI 0.01-0.78; P=0.03) were less likely to be treated. CONCLUSIONS: Adherence to treatment for HIV infection, as judged by the patient's physician, appears to have a major influence on the decision to begin treatment for HCV infection in coinfected patients. This calls for specific therapeutic education and adherence support in order to ensure timely anti-HCV therapy in this population.

RESUMEN

The impact of antiretroviral drug exposure and associated lipodystrophy and/or insulin resistance (IR) on advanced liver fibrosis in HIV/HCV-coinfected patients is not fully documented. We determined the prevalence of advanced liver fibrosis (defined by hepatic stiffness ≥9.5 kPa) and associated factors, focusing on the impact of highly active antiretroviral therapy and its major adverse effects (lipodystrophy and IR), in 671 HIV/HCV-coinfected patients included in the ANRS CO13 HEPAVIH cohort. One hundred ninety patients (28.3%) had advanced liver fibrosis. In univariate analysis, advanced liver fibrosis was significantly associated with male sex, higher body mass index, HCV infection through intravenous drug use, a lower absolute CD4 cell count, a longer history of antiretroviral treatment, longer durations of protease inhibitors, non-nucleoside reverse transcriptase inhibitors and NRTI exposure, lipodystrophy, diabetes, and a high homeostasis model assessment method (HOMA) value. The only antiretroviral drugs associated with advanced liver fibrosis were efavirenz, stavudine and didanosine. In multivariate analysis, male sex (OR 2.0, 95% CI 1.1-3.5; P = 0.018), HCV infection through intravenous drug use (OR 2.0, 95% CI 1.1-3.6; P = 0.018), lipodystrophy (OR 2.0, 95% CI 1.2-3.3; P = 0.01), median didanosine exposure longer than 5 months (OR 1.7, 95% CI 1.0-2.8; P = 0.04) and a high HOMA value (OR 1.1, 95% CI 1.0-1.2; P = 0.005) remained significantly associated with advanced liver fibrosis. Mitochondrial toxicity and IR thus appear to play a key role in liver damage associated with HIV/HCV-coinfection, and this should be taken into account when selecting and optimizing antiretroviral therapy. Antiretroviral drugs with strong mitochondrial toxicity (e.g. didanosine) or a major effect on glucose metabolism should be avoided.

RESUMEN

OBJECTIVES: The aims of the present study were to estimate the prevalence of renal impairment (RI) among HIV-infected adult patients and to investigate the associated factors. METHODS: A cross-sectional survey was conducted in a French hospital-based cohort. Clearance of creatinine (CC) was calculated using the Cockcroft-Gault formula. Four stages of RI were defined: mild (60-90 mL/min), moderate (30-60), severe (15-30) and end stage (<15). Logistic regression models were used to investigate factors associated with RI. RESULTS: The male/female ratio of the 2588 patients enrolled was 3:1 and the median age was 42 years. At the time of assessment of CC, the median CD4 count was 430 cells/microL and HIV plasma viral load (VL) was<50 copies/mL in 60%. The overall prevalence of RI was 39.0%: 34.2% mild, 4.4% moderate, 0.3% severe and 0.2% end-stage. Mild RI was associated with female gender [odds ratio (OR)=3.3: 95% CI 2.6-4.3)], age >50 years (OR=9.8: 7.4-13.0) and 40-50 years (OR=1.9: 1.5-2.4), body mass index (BMI) <22 kg/m(2) (OR=3.3: 2.7-4.3) and tenofovir exposure (OR=1.4: 1.0-1.9 for <1 year and OR=1.5: 1.2-2.0 for >1 year). Advanced RI (CC <60 mL/min) was associated with age >50 years (OR=5.6: 2.9-10.9) and 40-50 years (OR=2.2: 1.1-1.4), BMI <22 kg/m(2) (OR=1.5: 1.0-2.4), hypertension (OR=2.5: 1.4-2.5) and indinavir (IDV) exposure >1 year (OR=2.3: 1.5-3.6). CONCLUSION: This survey confirms the high prevalence of RI in HIV-infected patients and indicates the importance of the investigation of renal function especially in women, older patients, those with a low BMI or treated with tenofovir or IDV.

RESUMEN

BACKGROUND: More than 10 years after the introduction of combination antiretroviral therapy (cART), we examined the trend in the proportion of deaths caused by end-stage liver disease (ESLD) in HIV-infected adults in France between 1995 and 2005. DESIGN AND METHODS: In 2005, 34 departments prospectively recorded all deaths in HIV-infected patients who were followed in those departments (around 24 000). RESULTS: were compared with those of four previous cross-sectional surveys conducted since 1995 using the same methodology. Results Among 287 reported deaths in 2005, 100 (35%) were related to AIDS, and 48 (17%) to ESLD. Three out of four patients who died from ESLD-related causes had chronic hepatitis C. Excessive alcohol consumption was reported in approximately half of the patients (48%). At death, 62% of patients had undetectable HIV viral load and the median CD4 count was 237 cells/microL. From 1995 to 2005, the proportion of deaths caused by ESLD increased from 2 to 17% (P<0.001). The proportion of deaths caused by hepatocellular carcinoma increased from 5% in 1995 to 25% in 2005 (P=0.0337). CONCLUSIONS: Over the 10 years from 1995 to 2005, the proportion of deaths caused by hepatitis C virus-related ESLD has increased in HIV-infected patients. ESLD is currently a leading cause of death in this population, with hepatocellular carcinoma representing a quarter of liver-related deaths. Recommendations for the detection of hepatocellular carcinoma should be strictly applied in these patients.

RESUMEN

INTRODUCTION: The objective of this study was to analyse the influence of hospitalisation on the polypharmacy of elderly people in internal medicine. METHODS: Prescriptions before hospitalisation and after discharge were prospectively collected and analysed. The percentages of pharmaceutical medication classes used before and after hospitalisation were compared using marginal homogeneity's test for paired series. RESULTS: One hundred and sixteen patients (mean age: 79 years) were included in this study. The number of drugs prescribed amounted to 6.4 before hospitalisation and 6.7 at discharge. Hospitalisation did not lead to reduction in the amount of prescribed drugs but some medications were modified. We observed a significant reduction in beta-blockers (25 to 19.8%, P=0.035) and lipid-lowering drugs (21.6 to 15.5%, P=0.058). On the other hand, the laxative medication was increased at discharge (19.8 to 34.5%, P=0.001). Similarly, there was an increase in psycholeptic drugs after hospitalisation (34.5 to 44%, P=0.007). CONCLUSION: These results pointed out firstly the polypharmacy observed in elderly patients and secondly the difficulty to reassess prescriptions. Our results should heighten clinicians' awareness of polypharmacy of elderly patients and of the usefulness of performing an individual assessment of the various drugs prescribed to a patient. The hierarchical organisation of disorders and drugs should allow to optimise the safety of the medications and decrease iatrogenic events.

RESUMEN

A study was conducted to determine the nature and antimicrobial susceptibility of uropathogens in Mauritius in order to provide guidance on the empirical treatment of uncomplicated urinary tract infections. The study was based on urine samples sent for bacteriological investigation at the Central Health Laboratory from unhospitalized patients over a 3-month period. Information on organisms isolated in pure growth and their antibiotic susceptibility was collected and analyzed. Entero - bacteriaceae accounted for over 80% of the 260 isolates obtained during the study period, and showed high rates of resistance to ampicillin (80%), co-trimoxazole (50%), nalidixic acid (34%) and ciprofloxacin (26%). Resistance to mecillinam and fosfomycin were only 2% and 0% respectively. The high rate of antimicrobial resistance in Enterobacteriaceae in urine is cause for concern. Fluoroquinolones may not be very reliable for empirical treatment of urinary tract infections in Mauritius. Alternatives such as pivmecillinam and fosfomycin should be considered.

RESUMEN

OBJECTIVE: The aim of this study was to determine the incidence of abacavir discontinuation within the first two months of treatment and the link with a true hypersensitivity reaction (HSR). PATIENTS AND METHODS: A retrospective study was made between January 1998 and January 2006 on a cohort of HIV positive patients treated by abacavir delivered by the Bordeaux Saint-André University Hospital pharmacy. RESULTS: Six hundred (and) twenty-eight patients were included. The reasons for non-renewal of abacavir prescription within the first three months of treatment were investigated. Early discontinuation for adverse effects was reported in 32 patients (5.1%): proved diagnosis of HSR (N=10), uncertain diagnosis of HSR (N=8), and no HSR (N=14). The decision for discontinuation was taken by physician after consultation in 76% of cases.

RESUMEN

INTRODUCTION: Assessing disease activity in patients suffering from autoimmune diseases is complex. Symptoms are multiple, often subjective and there are no reliable biomarkers. Many activity scores have been implemented to compare treatment efficacy in clinical trials. Their use in clinical practice is largely unknown. We performed a practical survey to analyze the use of activity scores in clinical practice to consider treatment response and to assess the determinants of their use. METHODS: A sample of French internists answered a questionnaire about activity scores of systemic lupus erythematosus, Sjögren's syndrome, autoimmune myositis and necrotizing vasculitis of small vessels. The frequency of use of these tools, the causes of their non-use, and the general opinion of practitioners about the place of theses scores in current practice were described. RESULTS: The form was completed by 92 internists. Seventy percent of them supported the use of activity scores in consultations, but actually used them in less than 25% of patient visits. The reasons for the low use of these scores are mainly the ignorance of their existence (42%) and their length or complexity (28%). CONCLUSION: The discrepancy between the ratio of practitioners who believe that scores have a place in daily practice and their actual use shows that the current scores do not meet the needs. The implementation of easily usable activity scores in inflammatory diseases remains a challenge for the internists.

RESUMEN

PURPOSE: Morbidity and mortality related to neoplasia are increasing in HIV-infected patients. CURRENT KNOWLEDGE AND KEY-POINTS: The incidence of AIDS opportunistic infections dramatically decreased since the introduction of highly active antiretroviral therapy (HAART). Among AIDS-cancers, the incidences of Kaposi sarcoma and of cerebral lymphoma decreased in a same way than AIDS infections but the incidences of systemic non-Hodgkin lymphoma and of cervical cancer decreased less than the others and remain higher than in the general population. This suggests that other factors than the quantitative immune reconstitution could be implicated. The most recent and large studies have also shown a 1.7 to 3 fold increased risk of developing non-AIDS cancers in HIV-infected patients when compared to the general population without significant impact of HAART on incidence curves. These malignancies include Hodgkin disease, lung, anal, head and neck cancers, hemopathies, and conjunctival cancers. PERSPECTIVES: Epidemiologic survey will help to define priorities in terms of prevention and screening in this specific population and to evaluate interventions which should be systematically proposed (alcohol and tobacco cessation programs, viral coinfection). The own roles of HIV itself and of antiretrovirals as prooncogenic factors need to be assessed.

RESUMEN

INTRODUCTION: Autoimmune hepatitis (AIH) is a chronic inflammatory hepatic disorder, characterized by hypergammaglobulinemia and autoantibodies. In some cases, AIH can be associated with another liver disease; such as the hepatitis C-AIH overlap syndrome, which diagnosis and treatment may be delicate. EXEGESE: We report a type 1 AIH case in a HIV-HCV co-infected woman. AIH remission and HCV eradication were obtained with prednisone and interferon plus ribavirine. AIH relapse appeared with corticosteroid withdrawal and a new remission was obtained with immunosuppressive treatment associating prednisone and azathioprine, without opportunistic infection. CONCLUSION: This case illustrates diagnostic and therapeutic difficulties of hepatitis C-AIH overlap syndromes in an HIV-infected patient. To our knowledge, it is the first AIH case report in a HIV-HCV co-infected patient.
