International audience; Antibiotic treatment of native osteomyelitis caused by extended-spectrum β-lactamase-producing Enterobacterales (ESBL-PE) is a challenge. Limited epidemiological and outcome data are available. This retrospective cohort study included osteomyelitis patients with ESBL-PE infections treated in a reference centre for bone and joint infections (BJIs) between 2011–2019. Twenty-nine patients with native BJI (mean age, 44.4 ± 15.7 years) were analysed. Fifteen cases were paraplegic patients with ischial pressure sores breaching the hip capsule. Other cases included eight other hip infections, four tibial infections and two foot infections. Infections were mostly polymicrobial (n = 23; 79.3%), including Staphylococcus aureus (n = 13; 8 methicillin-resistant). Klebsiella pneumoniae (n = 13) was the most frequent ESBL-producing species identified, followed by Escherichia coli (n = 10), including 3 E. coli/K. pneumoniae co-infections, and Enterobacter spp. (n = 9). ESBL-PE were rarely susceptible to fluoroquinolones (n = 4; 13.8%). Most therapies were based on carbapenems (n = 22) and combination therapies (n = 19). The median duration of treatment was 41 (5–60) days. Primary control of the infection was achieved in 62.1% (18/29) of cases and up to 86.2% after second look surgeries, after a median follow-up of 6 (1–36) months. Infection with ESBL-producing K. pneumoniae was associated with failure (P = 0.001), whereas age, infection location, prior colonisation and antimicrobial therapy were not found to be predictors of outcome. ESBL-PE native BJIs are often polymicrobial and fluoroquinolone-resistant infections caused by K. pneumoniae, highlighting the need for expert centres with pluridisciplinary meetings with experienced surgeons.

Background It is unclear whether HIV infection affects the long‐term prognosis after an acute coronary syndrome (ACS). The objective of the current study was to compare rates of major adverse cardiac and cerebrovascular events after a first ACS between people living with HIV (PLHIV) and HIV‐uninfected (HIV−) patients, and to identify determinants of cardiovascular prognosis. Methods and Results Consecutive PLHIV and matched HIV− patients with a first episode of ACS were enrolled in 23 coronary intensive care units in France. Patients were matched for age, sex, and ACS type. The primary end point was major adverse cardiac and cerebrovascular events (cardiac death, recurrent ACS, recurrent coronary revascularization, and stroke) at 36‐month follow‐up. A total of 103 PLHIV and 195 HIV− patients (mean age, 49 years [SD, 9 years]; 94.0% men) were included. After a mean of 36.6 months (SD, 6.1 months) of follow‐up, the risk of major adverse cardiac and cerebrovascular events was not statistically significant between PLHIV and HIV− patients (17.8% and 15.1%, P =0.22; multivariable hazard ratio [HR], 1.60; 95% CI, 0.67–3.82 [ P =0.29]). Recurrence of ACS was more frequent among PLHIV (multivariable HR, 6.31; 95% CI, 1.32–30.21 [ P =0.02]). Stratified multivariable Cox models showed that HIV infection was the only independent predictor for ACS recurrence. PLHIV were less likely to stop smoking (47% versus 75%; P =0.01) and had smaller total cholesterol decreases (–22.3 versus –35.0 mg/dL; P =0.04). Conclusions Although the overall risk of major adverse cardiac and cerebrovascular events was not statistically significant between PLHIV and HIV− individuals, PLHIV had a higher rate of recurrent ACS.

Introduction et but de l’etude L’anorexie mentale (AM) est la pathologie psychiatrique avec le plus haut taux de mortalite, notamment a cause de la denutrition. L’immunodepression cellulaire induite par cette denutrition severe pourrait etre a l’origine de l’apparition d’infections pulmonaires chroniques opportunistes (IPCO). Seuls quelques cas d’IPCO dans l’AM ont ete rapportes dans la litterature. Le but de cette etude etait d’identifier les facteurs associes aux IPCO dans une population de patients denutris atteints d’AM. Materiel et methodes Une etude observationnelle a ete realisee dans un service soins tertiaires dedie aux patients atteints d’AM et severement denutris. Le diagnostic d’IPCO a ete fait sur la presence de lesions suggestives au scanner thoracique, associe ou non a une identification microbiologique. Chaque patient avec un diagnostic d’IPCO a ete apparie sur l’âge et le sexe a deux patients non malades, hospitalises au cours de la meme periode. Les variables suivantes ont ete recueillies : poids, IMC, CRP, albuminemie, transthyretine, neutrophiles, lymphocytes, et identification des germes a la culture des expectorations le cas echeant. Le test t de Student et la regression logistique ont ete effectues pour determiner les parametres associes aux IPCO. Une analyse discriminante et des courbes de ROC ont ete realisees pour les variables significatives en univariee. Resultats et analyse statistique Entre 2004 et 2020, 1441 patients ont ete hospitalises et 31 avaient un diagnostic d’IPCO (2,2 %). Les patients atteints d’IPCO avaient un IMC inferieur (11,5 vs 13,0 ; p = 0,02), un taux de lymphocytes sanguins plus bas (763 vs 1637/mm3 ; p Conclusion L’IPCO est une des complications somatiques observees chez les patients avec AM. Cette etude observationnelle a identifie le taux de lymphocytes comme etant le principal facteur predictif d’IPCO. Des etudes prospectives sont necessaires pour confirmer ce seuil en prospectif et juger de l’utilite de realiser un scanner thoracique systematique pour ces patients.

Resume Objectifs Pour les patients vivant avec le VIH (PVVIH) naifs, de nombreux schemas d’associations d’antiretroviraux (ARV) peuvent etre utilises et bien souvent ce choix reste subjectif. L’objectif de ce travail est d’evaluer les facteurs associes au choix des molecules en primo-prescriptions d’ARV. Patients et methodes Du 01/01 au 30/10/2014, toutes les primo-prescriptions d’ARV ont ete analysees (donnees patients et donnees prescripteurs), puis reevaluees par un groupe de praticiens « relecteurs ». Resultats Trente-quatre prescripteurs (dans 11 centres) ont inclus 132 patients : 71 H, migrants : 57 %, homosexuels : 21 %, CD4 3 : 26 %, charge virale VIH > 100 000 cp/mL : 33 %. Les schemas prescrits ont ete : INRT/IP (43 %), INRT/INNRT (29,5 %), INRT/anti-integrase (23 %). Le choix etait conforme aux recommandations dans 75 % des cas. Ni les facteurs de risque, ni l’origine des patients, ni le taux de CD4 n’ont influence le choix du 3 e agent. En revanche, ce choix etait influence par l’activite professionnelle ( p = 0,007), un desir de grossesse ( p = 0,07), une grossesse ( p = 0,001), la primo-infection ( p = 0,049) et le niveau de charge virale ( p = 0,02). Ni l’âge, ni l’anciennete dans la prise en charge des PVVIH, ni la taille de la file active de chaque prescripteur n’a influe le choix des ARV. La non-conformite etait principalement le fait de l’utilisation des anti-integrases ( p Conclusions La prescription d’ARV chez les patients naifs respecte globalement les recommandations. Les facteurs influencant les choix sont essentiellement lies a l’existence d’une primo-infection, aux particularites de la procreation, et au niveau de charge virale. Les 25 % de prescriptions non conformes aux recommandations temoignent de l’interet des praticiens pour les classes therapeutiques mieux tolerees.

Introduction Peu de cas de COVID-19 chez des patients infectes par le VIH ont ete rapportes dans la litterature. Nous decrivons les caracteristiques clinicobiologiques et l’evolution de la COVID-19 chez 10 patients infectes par le VIH. Materiels et methodes 10 patients (1,8 %) de notre file active de 560 patients ont eu la COVID-19 entre le 9 mars et le 30 avril 2020. Le diagnostic d’infection a Coronavirus SARS-CoV-2 a ete fait par amplification par PCR en temps reel du gene E du betacoronavirus sur ecouvillon nasopharynge. Resultats Dix patients infectes par le VIH-1, 6 hommes et 4 femmes, d’âge moyen 56 ans ont presente la COVID-19. L’infection par le VIH avait ete diagnostiquee depuis 19 ans environ (min : 6 mois, max : 32 ans). Sept patients sur 10 etaient classes stade C. Tous les patients avaient un traitement antiretroviral : tritherapie (9/10) ou bitherapie (1/10), une charge virale VIH indetectable et des LT CD4 > 200/mm3 (min : 295, max : 1350/mm3). Quatre patients ont ete hospitalises pour une pneumonie, 1 patiente avec antecedent de cancer du poumon a presente une pneumonie nosocomiale a SARS-CoV-2. Quatre patients ambulatoires avaient une infection respiratoire haute et 1 un tableau digestif isole. Les patients hospitalises pour pneumonie communautaire avaient des comorbidites : hypertension arterielle (4/4), diabete de type 2 (4/4), obesite (2/4), maladie respiratoire chronique (1/4). La presentation clinique comprenait : fievre (7/10), toux (7/10), anosmie et agueusie (3 des 5 patients ambulatoires) et troubles digestifs (3/10). La guerison survenait en 7 a 14 jours sous traitement symptomatique (formes ambulatoires). L’hospitalisation survenait entre 7 et 12 jours apres le debut des symptomes avec une duree d’hospitalisation de 8 a plus de 45 jours. Deux patients ont presente un SDRA : une decedee a 12 jours en medecine ; l’autre admis en reanimation avec ventilation mecanique pendant 2 mois. La patiente decedee a eu du ritonavir/lopinavir, une corticotherapie et un antagoniste du recepteur IL1. Les autres patients hospitalises ont recu : antibiotiques (4/5), hydroxychloroquine (2/5), antagoniste du recepteur C5 (1/5). Conclusion Les patients infectes par le VIH ont les memes presentations cliniques que ceux non infectes par le VIH avec des formes severes de COVID-19 survenant chez des patients ayant les facteurs de risque decrits dans la litterature (âge, comorbidites tels l’hypertension arterielle, le diabete, l’obesite ou une pathologie respiratoire chronique). Une infection par le VIH bien controlee sur le plan immunovirologique ne semble pas etre un facteur de risque de COVID-19. Par ailleurs, le traitement antiretroviral en cours ne semble pas etre un facteur protecteur contre l’infection a SARS-CoV-2. Une etude etiologique est necessaire pour confirmer ces hypotheses.

Background. Calendar trends in virologic failure (VF) among human immunodeficiency virus (HIV)-infected patients can help to evaluate the performance of healthcare systems and the need for new antiretroviral therapy (ART). We examined the time trend in the rate of VF beyond 6 months of ART between 1997 and 2011 in France. Methods. We included patients from the French Hospital Database on HIV who received at least 6 months of ART. VF was defined as 2 consecutive plasma HIV-RNA values >500 copies/mL or as 1 value >500 copies/mL followed byatreatment switch. We adjusted for patients’ characteristics by fitting a multivariable generalized estimating equation logistic regression model with an exchangeable covariance matrix. Results. A total of 81738 patients were enrolled, and median follow-up was 112.4 months. Median CD4 count was 333 cells/µL, and 23% of patients had HIV infection classified as Centers for Disease Control and Prevention stage C. Overall, 29.3% of patients received single/dual-drug ART initially, and 45.4% of patients experienced at least 1 episode of VF during follow-up. The percentage of patients with VF fell from 61.5% in 1997–1998 to 9.7% in 2009–2011 (P

The efficacy and safety of switching to a combined regimen containing darunavir/ritonavir (DRV/r) was investigated in a retrospective study.Sixty-six experienced patients receiving once-daily DRV/r (900/100 mg) in various regimens were included (median age 51 y; male 82%; Centers for Disease Control and Prevention (CDC) stages B or C 70%). The number of patients with plasma HIV RNA50 copies/ml increased from 71% (45/63) at baseline (before switch) to 84% (52/62) at visit 1 (weeks 3-11), and to 92% (60/65) at visit 2 (weeks 12-24). CD4 cells increased from 498 ± 201 cells/mm³ at baseline to 567 ± 232 cells/mm³ by visit 2. Good digestive and metabolic tolerance was observed. The median steady-state DRV plasma concentration, measured 24 ± 4 h after the last drug intake, was 1427 ng/ml. All DRV plasma concentrations were above the protein-binding corrected median effective concentration (EC₅₀) for the wild-type virus (55 ng/ml).Once-daily DRV/r (900/100 mg) was efficacious in pretreated patients, with safe responses.

Objectives The mechanism of raltegravir (RAL)-resistant evolutions has not already been elucidated. Because the emergence of RAL resistance is usually initiated by the N155H mutant, we assessed the role of minor N155H-mutated variants in circulating RNA and archived DNA in five heavily treated patients experiencing long-term RAL therapy failure and harbouring three different resistance profiles determined by standard genotyping. Methods Allele-specific polymerase chain reaction (AS-PCR) was used to detect N155H mutants in longitudinal stored plasma and whole-blood samples before, during and after RAL-based regimens in five patients infected with the HIV-1 B subtype. Results No minor N155H-mutated variant was found by AS-PCR in either plasma or whole-blood samples collected at baseline and after RAL withdrawal in any of the five patients. During RAL failure, the mutation N155H was detected at different levels in three patients displaying the N155H pathway and gradually declined when the double mutant Q148H+G140S was selected in one patient. In two patients with the Q148H resistance pathway, no N155H variant was identified by AS-PCR in either viral RNA or DNA. Conclusions The N155H mutation present at various levels from minority to majority showed no relationship with the three RAL-associated resistance profiles, suggesting that this mutant may not play a role in determining different resistance profiles. Moreover, pre-existing N155H is very infrequent and, if selected during RAL failure, the N155H mutant disappears quickly after RAL withdrawal.

Introduction Du fait de l’augmentation de l’âge des patients et du risque de vieillissement premature, le vieillissement des patients infectes par le VIH (PVVIH) devient une realite de sante publique. Afin d’ameliorer la prise en charge de cette population particuliere, nous avons realise une etude visant a evaluer les comorbidites associees des PVVIH âges de plus de 75 ans. Materiels et methodes Recueil standardise des caracteristiques demographiques, virologiques, immunologiques, therapeutiques des patients du Corevih âges de 75 ans et plus en 2016. Les comorbidites evaluees etaient les suivantes : insuffisance renale (ClCr

Background Darunavir (DRV) is the latest protease inhibitor (PI) to be approved for antiretroviral-naive and -experienced HIV-infected patients. Objectives We examined virologic and immunologic outcomes of highly antiretroviral-experienced patients with triple-class drug resistance receiving DRV/r-based regimens, and attempted to identify factors predictive of virologic success. Study design We studied patients beginning a ritonavir-boosted DRV (DRV/r 600/100 mg twice daily)-containing regimen. Virologic success was defined as plasma viral load (pVL) Results We studied 62 patients with very severe immunodeficiency (CDC stage C in 69% of cases; median CD4 cell nadir 12/mm3). They had previously received a median of four PI and had extensive PI resistance, with a median of three major PI and two DRV resistance mutations. The baseline median pVL and CD4 cell count values were 4.6 log10 and 150/mm3. At week 36, pVL had fallen by 2.6 log10 and the CD4 cell count had risen by 123 cells/mm3. The virologic success rate was 55% overall, and was improved by concomitant first use of enfuvirtide (67%), raltegravir (69%) or etravirine (75%). Virologic success was independently associated with fewer major PI mutations, previous tipranavir exposure, and concomitant first use of enfuvirtide or raltegravir. Conclusions In these highly antiretroviral-experienced patients with triple-class drug resistance, virologic success of DRV-containing regimens was mainly associated with the use of new drug classes and/or fully active drugs. Interestingly, previous tipranavir failure did not undermine the efficacy of DRV, confirming the low level of cross-resistance and, probably, distinct resistance profiles between DRV and tipranavir.

Resume Introduction La lymphogranulomatose venerienne (LGV) est une maladie sexuellement transmissible rare provoquee par Chlamydiae trachomatis serovar L. Depuis 2003–2004, on assiste a une epidemie de rectites liees a la LGV C. trachomatis (serovar L2b) chez des patients homosexuels masculins, en particulier infectes par le VIH, en Amerique du Nord et en Europe, y compris en France. Observation Un homme de 41 ans, infecte par le VIH, presentait depuis trois semaines une volumineuse lesion granulomateuse ulceree de la verge et une adenopathie inguinale sans atteinte rectale associee. Un traitement par doxycycline, 200 mg/j pendant trois semaines, permettait une disparition totale des lesions. La positivite de la recherche par PCR de C. trachomatis (serovar L2) sur les serosites de l’ulceration genitale confirmait le diagnostic de bubonulus genital lie a la LGV. Discussion Depuis le debut de la recente epidemie occidentale de rectites liees a la LGV, les descriptions cliniques de lesions genitales masculines sont rares. Le diagnostic de LGV doit etre systematiquement evoque devant une lesion genitale sexuellement transmise, meme devant un aspect atypique, surtout chez les patients infectes par le VIH.

Resume Situation La prevalence de l'infection a VIH (virus d'immunodeficience humaine) augmente en France, l'incidence restant elevee et les multitherapies antiretrovirales reduisant fortement la mortalite. Les personnes infectees par le VIH ont desormais une esperance de vie augmentee et sont susceptibles d'etre pris en charge en reanimation plus facilement. Methode Nous avons realise en France metropolitaine une enquete nationale comparative (82 etablissements de sante) portant sur les pratiques des reanimateurs ( n = 101) et des medecins referents ( n = 78) pour la prise en charge du VIH, afin de connaitre leurs attitudes therapeutiques concernant les antiretroviraux dans differentes situations de reanimation. Resultats Les resultats demontrent une heterogeneite importante dans les reponses des reanimateurs, avec une proportion importante de reponses « non tranchees ». L'attitude des medecins referents pour le VIH semble plus homogene. Il apparait une absence de collaboration entre les deux specialistes au sein des hopitaux. Les CISIH (Centres d'information et de soin de l'immunodeficience humaine) sont peu consultes. Conclusion Il est necessaire de renforcer les connaissances des reanimateurs vis-a-vis d'une pathologie et de traitements en constante evolution. L'acces a l'information actualisee ou a un medecin referent doit etre simplifie et il convient de developper des etudes sur la gestion des antiretroviraux en reanimation.

Resume Objectifs Caracteriser par une methode d’imagerie reproductible les redistributions adipeuses abdominales chez les patients infectes par le virus de l’immunodeficience humaine (VIH) cliniquement lipodystrophiques. Materiels et methodes 89 patients VIH cliniquement lipodystrophiques ont ete inclus dans l’etude. Une seule coupe axiale abdominale ponderee T1 passant par le milieu du corps de la quatrieme vertebre lombaire (L4) est realisee en apnee. Deux radiologues mesurent de facon semi-automatique les surfaces de tissu adipeux abdominales dans les regions sous-cutanees (SAT) et viscerales (VAT). Les mesures sont comparees a celles de temoins apparies (ethnie, sexe, âge et indice de masse corporelle). Resultats Les mesures de surfaces adipeuses abdominales en IRM sont reproductibles. Chez l’homme lipodystrophique : on decrit trois formes cliniques de lipodystrophie avec augmentation du tissu adipeux visceral (VAT) et diminution du tissu graisseux sous cutane (SAT) par rapport aux sujets sains. Chez les femmes, on retrouve deux formes cliniques de lipodystrophie avec une augmentation du VAT mais aucune diminution du SAT. Conclusion L’IRM avec comparaison malades-temoins apparies est une methode reproductible pour caracteriser les redistributions adipeuses de la lipodystrophie et en evaluer la severite. Un large referentiel IRM de distribution du tissu adipeux abdominal sur temoins serait utile a l’etude des pathologies metaboliques.

29-69 % of pneumonias are microbiologically documented because it can be considered as an invasive procedure with variable test sensitivity. However, it drastically impacts therapeutic strategy in particular the use of antibiotics. Serum protein electrophoresis (SPEP) is a routine and non-invasive test commonly used to identify serum protein disorders. As virus and bacteria may induce different globulins production, we hypothesize that SPEP can be used as an etiological diagnosis test. Retrospective study conducted from 1/1/13 until 5/1/15 among patient hospitalized for an acute community-acquired pneumonia based on fever, crackles and radiological abnormalities. α/β, α/γ, β/γ globulins and albumin/globulin (A/G) ratio were calculated from SPEP. Data were analyzed in 3 groups: documented viral (DVP) or bacterial pneumonia (DBP) and supposedly bacterial pneumonia (SBP). We used ANOVA statistic test with multiple comparisons using CI95 and ROC curve to compare them. 109 patients included divided into DBP (n = 16), DVP (n = 26) and SBP (n = 67). Mean age was 62 ± 18 year-old with a sex ratio M/F of 1.3. Underlying conditions (e.g. COPD, diabetes) were comparable between groups in multivariate analysis. Means of A/G ratio were 0.80 [0.76-0.84], 0.96 [0.91-1.01], 1.08 [0.99-1.16] respectively for DBP, SBP and DVP (p = 0.0002). A/G ratio cut-off value of 0.845 has a sensitivity of 87.5 % and a specificity of 73.1 %. A/G ratio seems to be an easy diagnostic tool to differentiate bacterial from viral pneumonia. A/G ratio cut-off value below 0.845 seems to be predictable of a bacterial origin and support the use of antibiotics.

Background Thirteen clustered cases of American histoplasmosis, a deep mycosis caused by Histoplasma capsulatum and acquired through inhalation of airborne spores was reported. Twenty-five persons traveled in Martinique, French West Indies. Thirteen underwent trekking and passed through a mountain tunnel full of bats (tunnel group). The 12 others performed canyoning and did not go through the tunnel (control group). Fifteen days after exposure, 1 patient of the tunnel group developed fever, chills, and cough. Methods The index case was diagnosed in the hospital, but 12 cases where initially diagnosed as prolonged influenza. All individuals were contacted and submitted to a phone questionnaire. They were asked about eventual occurrence of influenzalike symptoms, about activities practiced, and the notion of contact with bats. All were invited to have clinical examinations, chest x-ray films, and blood samplings. Serologic testing for histoplasmosis was performed by immunodiffusion. Clinical evidence of infection with H. capsulatum was obtained in all the remaining patients of the tunnel group and in none in the control group. Symptoms occurred with an acute onset in 11 to 23 days: fever and chills, severe asthenia, headaches, digestive tract involvement, and then cough, dyspnea, hepatic involvement. Pulmonary micro- or macronodules and mediastinal adenopathies were seen on radiograph and/or computed tomography scan. ResultsH. capsulatum serologic tests were positive in all 13 cases with presence of specific M and or H precipitins, 5 to 13 weeks after exposure, and were negative in control group. All patients were treated with itraconazole 200 mg per day during at least 2 months. Treatment was well tolerated; patients progressively recovered. Clinical and serologic follow-up was obtained for some patients at 1 and 4 years. The present study reports the first large outbreak of histoplasmosis acquired in Martinique. Conclusion Histoplasmosis still occurs and is potentially serious. In patients returning from endemic areas, presenting prolonged influenzalike symptoms, clinicians should look for previous possible exposure to Histoplasma.

Treating Hepatitis C among HIV patients under antiretroviral drug therapy requires a high degree of vigilance and continuous monitoring because of frequent problems with intolerance and/or drug interactions. Recent studies, including three therapeutic trials, on Ribavic, APRICOT, and ACTG A5671, have given some insights on following these patients up. The adverse effects are relatively similar in HCV-HIV-co-infected patients and patients infected by HCV only. Their frequency is, on the other hand, higher among HCV-HIV-Co-infected patients. The adverse-effects are consistent, in a non-exhaustive way, with pseudo influenza-like symptoms, fever, myalgia, cephalgia, with psychiatric disorders (irritability, depression, etc.); endocrine disorders (thyroid dysfunction, diabetes...); and with hematological anomalies especially anemia and leucopenia. But the percentage of lymphocyte T CD4 is not modified, therefore there is no risk of opportunistic infection. Pharmacokinetic interactions between antiretroviral drugs and treatment for HCV infection including ribavirin plus interferon alpha (IFN-alpha) or pegylated IFN are described. They are almost exclusively due to the combination of ribavirin and of nucleoside analogue reverse transcriptase inhibitors. One of the principal consequences is the emergence of mitochondrial toxicity defined by the occurrence of hyperlactatemia, or acute pancreatitis). Thus, some combinations should be avoided such as ddI+ribavirin and ddI+d4T+ribavirin. The d4T+ribavirin combination must also be used with caution.

Background We have previously shown that lipid alterations in HIV-1-associated lipodystrophy (LD) are correlated with decreased serum dehydroepiandosterone (DHEA) and increased cortisol:DHEA ratio and IFN-α levels. Objective To evaluate in a longitudinal study whether steroid and cytokine modifications are associated with the evolution of physical changes and lipid alterations associated with LD. Methods Thirty-four HIV-1-positive men were followed during 32·5 ± 4·0 months and tested at four time-points. The patients were subdivided into five groups according to physical changes and anthropometric measurements: LD-negative, initially LD-negative becoming LD-positive, LD-positive unchanged, aggravated or improved. Serum lipids, apolipoproteins, adrenal steroids and cytokines were measured and compared with baseline values. Results (1) LD aggravation is associated with persistent elevated lipids, a decrease in serum DHEA, an increase in cortisol:DHEA ratio and persistent high levels of IFN-α. (2) LD improvement is associated with normalization of serum lipids, an increase in serum DHEA leading to normalization in cortisol:DHEA ratio, and normalization of IFN-α levels. (3) In LD-positive men evolution of VLDL cholesterol is negatively correlated with DHEA (r = −0·56, P

Gonococcal arthritis is typically acute and appears within 3 weeks after initial infection. Chronic gonococcal arthritis is now exceptionally rare, since the advent of the antibiotic era. Numerous host factors are involved in gonococcal dissemination, such as complement deficiency, HIV and gonococcus strain characteristics. Gonococcal arthritis shares the same risk factors. In this instance, our patient was a 16-year-old girl suffering from persistent polyarthralgia with joint swelling presenting with brief flare-ups for a period of 1 year. She disclosed a single episode of unprotected sexual intercourse 1 year ago, i.e. just before developing her first rheumatological symptoms. Therefore, we performed a joint aspiration (arthrocentesis), and synovial fluid was inoculated directly into aerobic and anaerobic blood culture bottles, which tested positive for Neisseria gonorrhoeae within 24 h. Clinical presentation was consistent with previous reports of chronic gonococcal arthritis. Further investigation revealed a C5 complement deficiency, which might explain the chronic Neisseria process. A favourable outcome was reached after a ten-day course of IV ceftriaxone, with no apparent sequelae found during follow-up 6 weeks later. This case demonstrates an unusual gonococcal arthritis with brief flare-ups for the course of a year, followed by a subacute form. N. meningitidis infections, similar to N. gonorrhoeae, are typically acute and may sometimes be involved in chronic processes. However, this characteristic appears to be rare in the case of N. gonorrhoeae. Risk factors for this chronic process will be discussed with a review of the literature.

Objective To assess the efficacy of highly active antiretroviral treatment (HAART) on AIDS-Kaposi's sarcoma (KS). Design Prospective cohort of patients followed for 24 months. Setting Four referral hospitals of the West Paris metropolitan area. Patients/intervention Thirty-nine AIDS-KS patients, 42 +/- 9 years old, who began HAART (HIV-protease inhibitor and two nucleoside analogues) between March and December 1996, were enrolled. One was lost to follow-up at month 12. Main outcome measures KS response, using criteria of the AIDS clinical trials group (ACTG), CD4 cell counts, and plasma HIV-RNA, assessed every 6 months. ACTG TIS staging of KS. Results Eighteen patients had T1 KS and 21 T0 KS. One patient died from KS at month 6. KS improved progressively, with complete and partial response rates of 46% and 28% at month 24, respectively. Only six patients were still receiving systemic KS therapy at month 24. Complete response was observed in 10 of the 19 patients without systemic KS therapy at inclusion. Patients with complete response at month 24 had higher CD4 cell counts than others (465 +/- 343 versus 185 +/- 167 x 10(6)/l; P 150 x 10(6)/l [odds ratio (OR), 13.4; 95% confidence interval (CI), 2-82] and T0 KS at inclusion: [OR, 7; 95% CI, 1.1-42] were predictive of complete response at month 24. Conclusions HAART appears to have prolonged efficacy on AIDS-KS, even without specific KS therapy, and this effect appears to be linked to the restoration of immune function.

Background: A syndrome of lipodystrophy, associated with hypertriglyceridaemia, hypercholesterolaemia, hyperinsulinaemia and peripheral insulin resistance has been reported in protease inhibitor (PI)-treated HIV-infected patients. Because lipid metabolism, fat mass distribution and insulin resistance are partly regulated by steroid hormones, we questioned whether lipodystrophy is related to hormonal perturbations. Objective: To evaluate serum lipid and steroid hormone concentrations in HIV-positive men on highly active antiretroviral therapy (HAART) in order to determine whether dyslipidaemia, peripheral loss of fatty tissue and central fat accumulation are related to steroid hormone modifications. Design: A cross-sectional study. Methods: Thirty-seven HIV-1-positive men on HAART, 23 of whom had symptoms of lipodystrophy, according to a subjective clinical score of lipodystrophy (SCSL), were tested. Serum concentrations of cholesterol, triglycerides and their subclasses, apolipoproteins and steroid hormones, including cortisol, dehydroepiandrosterone (DHEA), DHEA sulphate, androstenedione, testosterone and dihydrotestosterone were measured. Results: Serum cholesterol, very low density lipoprotein (VLDL) cholesterol, triglycerides, VLDL triglycerides, high density lipoprotein (HDL) and low density lipoprotein (LDL) triglycerides, apolipoprotein B (ApoB) and atherogenic ratios of cholesterol:HDL cholesterol, LDL cholesterol:HDL cholesterol and ApoB:apolipoprotein A1 (ApoA1) were significantly increased in lipodystrophy-positive compared with lipodystrophy-negative men. The serum cortisol level was similar in lipodystrophy-positive versus lipodystrophy-negative men, but was elevated compared with controls. Serum DHEA was significantly lower in lipodystrophy-positive versus lipodystrophy-negative men and, consequently, the cortisol:DHEA ratio was increased in lipodystrophy-positive patients. A positive correlation was found between the cortisol:DHEA ratio and increased levels of atherogenic lipids. In addition, the SCSL was positively correlated with dyslipidaemia and the cortisol:DHEA ratio. Conclusion: This study demonstrates an association between the cortisol:DHEA ratio, lipid alterations and lipodystrophy. This syndrome might result from an imbalance between peripheral lipolysis and lipogenesis, both regulated by cortisol and DHEA.

Twenty-four cerebrospinal fluid (CSF) samples from 19 AIDS patients with neurological signs were analysed by the polymerase chain reaction (PCR) for the presence of JC virus (JCV). Eleven of the 19 patients tested presented with progressive multifocal leucoencephalopathy (PML). Two specific JCV target sequences were used for the PCR analysis: a sequence specific for the T antigen genes from both BK virus (BKV) and JCV (PCR1) and a sequence specific for the large T antigen gene from JCV (PCR2). The JCV genome was detected in 10 of 11 patients with PML by the PCR1 method and in all 11 patients by the PCR2 method. With samples from the eight patients without PML, one positive result was obtained with the PCR1 method and this sample and another gave positive results with PCR2. Multiple CSF samples were collected from three patients with PML at different times, including after intrathecal cytarabine treatment, and were tested by the PCR2 method for the presence of the JCV genome. The PCR result became negative for two of the three patients during the cytarabine treatment. However, the absence of a PCR signal was not associated with clinical improvement in these patients. The PCR method is useful for the detection of JCV in CSF samples and in the diagnosis of PML. However, the application of PCR for monitoring the effect of treatment remains to be established.

The recent augmentation of the prevalence of multidrug resistant (MDR) tuberculosis is related to the high incidence of tuberculosis in HIV infected people, especially in those with low social status and no medical care; several nosocomial epidemics of MDR tuberculosis were observed in American and European institutions where HIV-infected persons were hospitalized; these MDR tuberculosis were associated with a high mortality-rate and frequent nosocomial transmission to immunocompromised contacts and care workers. The rapid institution of an adequate treatment with ancient antituberculosis agents (cycloserin, capreomycin, aminoglycosides) and/or new drugs (rifabutine, ofloxacin, sparfloxacin, etc) is necessary to avoid mortality and to diminish transmission. Prevention of MDR tuberculosis transmission is very important: patient isolation, adequate and prolonged therapy, better detection of resistance with gene-amplification methods (PCR) which are under investigation.

The mechanism of raltegravir (RAL)-resistant evolutions has not already been elucidated. Because the emergence of RAL resistance is usually initiated by the N155H mutant, we assessed the role of minor N155H-mutated variants in circulating RNA and archived DNA in five heavily treated patients experiencing long-term RAL therapy failure and harbouring three different resistance profiles determined by standard genotyping.Allele-specific polymerase chain reaction (AS-PCR) was used to detect N155H mutants in longitudinal stored plasma and whole-blood samples before, during and after RAL-based regimens in five patients infected with the HIV-1 B subtype.No minor N155H-mutated variant was found by AS-PCR in either plasma or whole-blood samples collected at baseline and after RAL withdrawal in any of the five patients. During RAL failure, the mutation N155H was detected at different levels in three patients displaying the N155H pathway and gradually declined when the double mutant Q148H+G140S was selected in one patient. In two patients with the Q148H resistance pathway, no N155H variant was identified by AS-PCR in either viral RNA or DNA.The N155H mutation present at various levels from minority to majority showed no relationship with the three RAL-associated resistance profiles, suggesting that this mutant may not play a role in determining different resistance profiles. Moreover, pre-existing N155H is very infrequent and, if selected during RAL failure, the N155H mutant disappears quickly after RAL withdrawal.

Ten severely immunocompromised HIV–HCV co-infected patients were enrolled in a quantifiable HCV-RNA assay. Serum alanine aminotransferase, HCV-RNA levels and HIV viral loads were determined at baseline, at month three and at month six after initiation of a highly active antiretroviral therapy including an HIV protease inhibitor. HCV genotypes were determined using a line probe assay kit. Our results suggested that this therapy did not result in lower HCV viraemia, whatever the HCV genotypes, and probably had no effect on the outcome of chronic viral hepatitis C. As our patients were severely immunocompromised and their mean increase of CD4 cell counts was less than 50/mm 3 , we cannot reach any conclusions about the impact of the improvement of immune status on the HCV-RNA load.

Resume L'objectif de cette etude ouverte prospective etait d'evaluer l'interet des aerosols d'isethionate de pentamidine a la dose quotidienne de 300 mg dans le traitement de relais de 13 episodes de pneumocystose survenus chez des patients atteints de syndrome d'immunodeficience acquise. Les aerosols de pentamidine ont ete administres dans 11 cas apres un traitement d'une duree moyenne de 10 jours par l'association trimethoprime-sulfamethoxazole, et dans 2 cas apres 6 jours de traitement par la pentamidine intraveineuse. Apres une duree totale du traitement anti-Pneumocystis de 21 jours, tous les patients ont ete consideres gueris sur les criteres cliniques. Une aggravation des anomalies radiologiques et gazometriques a ete constatee chez deux patients presentant une pathologie pulmonaire associee (tuberculose et sarcome de Kaposi). La tolerance des aerosols de pentamidine a ete bonne. Deux patients ont developpe des signes de surinfection bronchique. Au total, cette etude montre l'interet du traitement sequentiel — traitement par voie generale puis locale — des pneumocystoses non severes liees au SIDA.

Solid organ transplantations (SOT) are performed successfully in selected HIV-infected patients. However, multiple and reciprocal drug–drug interactions are observed between antiretroviral (ARV) drugs and calcineurin inhibitors (CNIs) through CYP450 metabolization. Raltegravir (RAL), a novel HIV-1 integrase inhibitor, is not a substrate of CYP450 enzymes. We retrospectively reviewed the outcomes of 13 HIV-infected transplant patients treated by an RAL + two nucleosidic reverse transcriptase inhibitor (NRTI) regimen, in terms of tolerability, ARV efficacy (plasma viral load, CD4 cell count), drug interactions, RAL pharmacokinetics and transplant outcome. Thirteen patients with liver (n = 8) or kidney (n = 5) transplantation were included. RAL was initiated (400 mg BID) either at time of transplantation (n = 6), or after transplantation (n = 7). Median RAL trough concentration was 507 ng/mL (176–890), which is above the in vitro IC95 for wild type HIV-1 strains (15 ng/mL). Target trough levels of CNIs were promptly obtained with standard dosages of tacrolimus or cyclosporine. RAL tolerability was excellent. There was no episode of acute rejection. HIV infection remained controlled. After a median follow-up of 9 months (range: 6–14), all patients were alive with satisfactory graft function. The use of an RAL + two NRTI-based regimen is a good alternative in HIV-infected patients undergoing SOT.

We have previously shown that lipid alterations in HIV-1-associated lipodystrophy (LD) are correlated with decreased serum dehydroepiandosterone (DHEA) and increased cortisol:DHEA ratio and IFN-alpha levels.To evaluate in a longitudinal study whether steroid and cytokine modifications are associated with the evolution of physical changes and lipid alterations associated with LD.Thirty-four HIV-1-positive men were followed during 32.5 +/- 4.0 months and tested at four time-points. The patients were subdivided into five groups according to physical changes and anthropometric measurements: LD-negative, initially LD-negative becoming LD-positive, LD-positive unchanged, aggravated or improved. Serum lipids, apolipoproteins, adrenal steroids and cytokines were measured and compared with baseline values.(1) LD aggravation is associated with persistent elevated lipids, a decrease in serum DHEA, an increase in cortisol:DHEA ratio and persistent high levels of IFN-alpha. (2) LD improvement is associated with normalization of serum lipids, an increase in serum DHEA leading to normalization in cortisol:DHEA ratio, and normalization of IFN-alpha levels. (3) In LD-positive men evolution of VLDL cholesterol is negatively correlated with DHEA (r = -0.56, P0.01) and positively with cortisol:DHEA ratio (r = 0.62, P0.004) and with IFN-alpha (r = 0.57, P0.01). (4) The switch to LD is associated with a decrease in serum DHEA. (5) Patients who remained LD-negative maintained normal lipids, elevated cortisol and DHEA, and normal cortisol:DHEA ratio and normal levels of IFN-alpha.This study indicates that cortisol:DHEA ratio and serum IFN-alpha levels are closely associated with clinical evolution and atherogenic lipid alterations in LD.

To assess the efficacy of highly active antiretroviral treatment (HAART) on AIDS-Kaposi's sarcoma (KS).Prospective cohort of patients followed for 24 months.Four referral hospitals of the West Paris metropolitan area.Thirty-nine AIDS-KS patients, 42 +/- 9 years old, who began HAART (HIV-protease inhibitor and two nucleoside analogues) between March and December 1996, were enrolled. One was lost to follow-up at month 12.KS response, using criteria of the AIDS clinical trials group (ACTG), CD4 cell counts, and plasma HIV-RNA, assessed every 6 months. ACTG TIS staging of KS.Eighteen patients had T1 KS and 21 T0 KS. One patient died from KS at month 6. KS improved progressively, with complete and partial response rates of 46% and 28% at month 24, respectively. Only six patients were still receiving systemic KS therapy at month 24. Complete response was observed in 10 of the 19 patients without systemic KS therapy at inclusion. Patients with complete response at month 24 had higher CD4 cell counts than others (465 +/- 343 versus 185 +/- 167 x 10(6)/l; P0.01), but the proportion of patients with HIV-1 RNA500 copies/ml was not significantly different. An increase in CD4 cell counts from inclusion to month 12 of150 x 10(6)/l [odds ratio (OR), 13.4; 95% confidence interval (CI), 2-82] and T0 KS at inclusion: [OR, 7; 95% CI, 1.1-42] were predictive of complete response at month 24.HAART appears to have prolonged efficacy on AIDS-KS, even without specific KS therapy, and this effect appears to be linked to the restoration of immune function.

Highly-active antiretroviral therapy (HAART) has lead to a dramatic decrease in the morbidity of patients infected with the human immunodeficiency virus (HIV). However, metabolic side effects, including lipodystrophy-associated (LD-associated) dyslipidemia, have been reported in patients treated with antiretroviral therapy. This study was designed to determine whether successful HAART was responsible for a dysregulation in the homeostasis of tumor necrosis factor-alpha (TNF-alpha), a cytokine involved in lipid metabolism. Cytokine production was assessed at the single cell level by flow cytometry after a short-term stimulation of peripheral blood T cells from HIV-infected (HIV(+)) patients who were followed during 18 months of HAART. A dramatic polarization to TNF-alpha synthesis of both CD4 and CD8 T cells was observed in all patients. Because it was previously shown that TNF-alpha synthesis by T cells was highly controlled by apoptosis, concomitant synthesis of TNF-alpha and priming for apoptosis were also analyzed. The accumulation of T cells primed for TNF-alpha synthesis is related to their escape from activation-induced apoptosis, partly due to the cosynthesis of interleukin-2 (IL-2) and TNF-alpha. Interestingly, we observed that LD is associated with a more dramatic TNF-alpha dysregulation, and positive correlations were found between the absolute number of TNF-alpha CD8 T-cell precursors and lipid parameters usually altered in LD including cholesterol, triglycerides, and the atherogenic ratio apolipoprotein B (apoB)/apoA1. Observations from the study indicate that HAART dysregulates homeostasis of TNF-alpha synthesis and suggest that this proinflammatory response induced by efficient antiretroviral therapy is a risk factor of LD development in HIV(+) patients.

Introduction et but de l’etude L’existence de perturbations des tests hepatiques au cours de l’anorexie mentale est decrite dans la litterature depuis plusieurs annees. Nous avons souhaite analyser les anomalies du bilan hepatique au cours des denutritions graves chez des patients atteints d’anorexie mentale, et observer leur evolution au cours de la renutrition enterale Materiel et methodes Etude retrospective monocentrique de la biologie hepatique chez des patients atteints d’anorexie mentale severement denutris (37 dossiers selectionnes au hasard parmi un collectif de 204 pris en charge entre Janvier 1998 et Octobre 2006). Criteres d’exclusion : affection hepatique, prise de medicaments hepatotoxiques ou d’alcool pouvant expliquer la perturbation du bilan hepatique. Resultats Parmi les patients inclus, 34 etaient des femmes (95 %). L’âge moyen etait de 28 ans ± 11, l’IMC moyen a l’admission etait de 12 ± 2,0, On a observe a l’admission une cytolyse hepatique chez 17 (46 %) patients. Leur IMC a l’admission etait de 10,9 ± 1,4; leur âge 25,4 ± 18. Ils presentaient une augmentation moyenne des ASAT a 8N, mediane (Extreme) 84 (46-1620), et ou des ALAT a 8N, mediane (Extreme) 215 (57-2614).L’evolution du bilan hepatique a la fin de la premiere semaine apres la mise en route d’une alimentation enterale progressive, associee a une supplementation en vitamines, oligoelements et phosphore etait favorable chez 16 des 17 patients (94 %) avec une moyenne des ASAT a 3N, mediane (Extreme) 65 (29-225) et Des ALAT a 4N, mediane (Extreme) 137 (55-1129). La normalisation totale du bilan hepatique est observee a la 4 e semaine d’hospitalisation. Une seule patiente a cependant presente une aggravation secondaire des transaminases sous alimentation entrale apres amelioration initiale avec des ASAT 10N et ALAT 8N a la 4 e semaine, un retour a des valeurs normales est observe au bout de la 7 e semaine ; elle avait par ailleurs presente une hypophosphoremie majeure a l’admission et un TP a 40 %. L’IMC moyen des patients presentant une cytolyse hepatique etait de 11,7 ± 1,6 a la 4 e semaine.Les patients n’ayant pas presente de cytolyse hepatique a l’admission, etaient âges de28 ans ± 11.Leur IMC a l’admission etait de 13,4 ± 2 et a 14 ± 2a la 4 e semaine de renutrition. Le reste du bilan hepatique etait peu perturbe. Conclusions Pres de la moitie des patients denutris severes atteints d’anorexie mentale admis pour renutrition enterale presentent une augmentation systematique des transaminases, ils avaient a l’admission un IMC inferieur et etaient plus jeunes que les patients ayant un bilan hepatique normal. L’evolution est rapidement favorable des la premiere semaine d’hospitalisation dans la majorite des cas. La normalisation des transaminases parallelement a la prise de poids a concerne tous les patients au terme d’un mois d’alimentation enterale progressive associee a une supplementation en vitamines et oligo-elements. Par ailleurs, une meilleure connaissance des mecanismes a l’origine des perturbations du bilan hepatique necessiterait certainement des etudes prospectives plus completes chez les patients atteints d’anorexie-mentale.

In order to test the hypothesis that a combination of protease inhibitors with nucleoside analogues-agents known to inhibit different steps of the human immunodeficiency virus (HIV) life cycle--is likely to prove more effective in reducing viral loads than either of those modalities alone, we performed a 60 week, open-label trial in 32 HIV-positive patients with depressed CD4 T lymphocyte cell counts but no active AIDS-defining illnesses. For the first 2 weeks, patients received 600 mg twice daily of liquid ritonavir, a protease inhibitor; then zidovudine 200 mg three times daily and zalcitabine 0.75 mg three times daily were added to the treatment regimen. Mononuclear blood cell fractions were analysed for infected cell levels, using a co-culture system. HIV-1 RNA in plasma was measured both by reverse transcriptase-polymerase chain reaction (RT-PCR) and reverse transcriptase quantitative PCR (QcRT-PCR); lymphocyte counts were determined by standard laboratory methods. In the 2 weeks of ritonavir therapy, both the mean count of infectious blood cells and plasma HIV RNA levels decreased dramatically. Mean CD4 cell counts increased from 173 cells/mm3 at baseline to 286 cells/mm3; CD8 cell counts rose from 951 cells/mm3 to 1,141 cells/mm3. With the introduction of the nucleoside analogues, infectious cell counts and plasma virus dropped another log unit to a nadir at 8 weeks, while CD4 T lymphocyte counts continued to rise slowly. By week 28, 12 patients had withdrawn due to adverse events, none of which were life-threatening. At week 36, infectious material could not be detected in the cells of 10 of the 17 remaining patients; by week 60, four of the seven patients with residual viraemia at week 24 had undergone viral relapse. After the introduction of a more palatable capsule formulation of ritonavir at week 52, infectious cells and plasma virus were undetectable in 50-60% of patients. The combination of protease inhibitors and nucleoside analogues significantly reduces HIV load, and in some patients may suppress viral activity for sustained periods.

Herpetic esophagitis (HE) associated with human immunodeficiency virus (HIV) is a rare condition mainly reported as isolated cases. We thus decided to study this association and analyze the possible predisposing factors, clinical and endoscopic presentations, and clinical response to treatment. Thirty-four HIV-1-infected patients were identified: 27 had histologically or virologically confirmed HE and seven had probable HE, a retrospective diagnosis based on the efficacy of acyclovir given alone. The median CD4 cell count was 15/mm3. Recent predisposing factors (such as nasogastric procedures, steroid therapy, and anticancer therapy) were noted with regard to 16 of the 34 patients (47%). Odynophagia and/or chest pain occurred in 30 patients (88%). At the time of diagnosis of HE, extraesophageal herpes was found in only 13 patients (38%). Superficial ulcers of the distal third of the esophagus were present in 17 (50%). Among 20 of the 27 patients with confirmed HE that could be evaluated, therapy with acyclovir led to complete resolution in 16 and partial response in 3; 1 patient died of HE. Five patients (15%) suffered confirmed or possible relapses. The mean interval between the diagnosis of HE and death was 8.8 months. Herpes simplex virus may be responsible for ulcerated esophagitis that occurs in the advanced stages of AIDS and that can be safely treated with acyclovir before a definitive diagnosis is made.

Introduction La citrullinemie est un biomarqueur innovant de la masse enterocytaire [1]. Elle constitue un parametre integre de la fonction absorptive globale de la muqueuse intestinale en situation chirurgicale, medicale et oncologique. Cependant les donnees evolutives sont rares, la majorite des etudes etant transversales. But determiner la citrullinemie, son evolution et sa valeur pronostique, dans les enteropathies medicales immunologiques, infectieuses et toxiques. La maladie VIH a ete prise comme modele. Patients et Methodes Trois groupes de patients (n = 53 ; 43H, 10F ; 43 (24 - 68) ans) ont ete prospectivement suivis pendant une duree mediane de 16 (6 - 37) mois avec 3 (2 -15) dosages, selon le contexte : 1) patients sans signes digestifs (n = 16) ; 2) patients non immunodeprimes (CD4 > 200/mm3) ayant une diarrhee du fait d’un effet toxique du traitement antiretroviral (ARV) (n = 12) ; 3) patients immunodeprimes (CD4 Resultats Chez les patients sans signes digestifs la citrullinemie ne se modifiait pas (36 ± 6 μmol/L vs 38 ± 8 chez les controles). Lors de gastro-enterite aigue de rencontre (n = 4) la citrullinemie baissait (19 ± 5 vs 34 ± 7) puis revenait a sa valeur basale en moins d’un mois. Lors d’enteropathie toxique, la citrullinemie augmentait quand l’ARV pouvait etre arrete ou substitue (n = 6, 22 ± 4 vs 42 ± 14, P 10). Aucun seuil ne pouvait etre determine pour la nutrition enterale (n = 10). Une correlation (P 6 mois d’une citrullinemie 20, P Conclusion La citrullinemie constitue un marqueur fiable de la fonction enterocytaire et de son evolution au cours des traitements specifiques. Elle determine les consequences fonctionnelles des enteropathies et notamment l’indication d’une nutrition parenterale. Elle constitue de plus un marqueur pronostique defavorable si elle reste inferieure a 20 μmol/L.

Introduction L’existence de perturbations des tests hepatiques dans l’anorexie mentale (AM) est decrite. La physiopathologie et la gravite potentielle de cette atteinte hepatique sont mal connues. L’objectif de ce travail a ete d’analyser les anomalies des tests hepatiques au cours des denutritions graves chez les patients atteints d’AM, d’identifier les facteurs de risque de survenue et d’observer leur evolution au cours de la renutrition. Patients et Methodes Etude retrospective sur un echantillon de patients AM hospitalises pour renutrition entre 1996 et 2006. Une perturbation du bilan hepatique a ete definie par une augmentation des ASAT et/ou des ALAT > 2N. Criteres d’inclusion : AM (definition DSM-IV), denutrition definie par un indice de masse corporelle (IMC) 18. Resultats Soixante six patients ont ete inclus. Sex ratio 62 F/4 H. AM restrictive pure 42 (63,6 %), des conduits purgatives associees 24 (36,3 %). L’âge moyen etait de 28,7 ± 11 ans, IMC 12,3 ± 1,9, albuminemie 36,7 ± 7 g/L. Tous les patients ont beneficie d’une renutrition progressive (enterale et/ou orale), selon les besoins calcules, associee a une complementation en vitamines, oligo-elements et phosphore. Plus de la moitie des patients (39, 59 %), IMC 12,9 ± 2,0, âge 30,6 ± 12, n’avait pas de cytolyse hepatique a l’admission. Aucun de ces patients n’a secondairement developpe d’hypertransaminasemie. Il existait une cytolyse a l’admission chez 41 % (n = 27) des patients, 78 % presentaient une AM restrictive pure, IMC 11,4 ± 1,9 ; âge 25,9 ± 7 ans. Ils presentaient une augmentation mediane des ASAT a 4N (extremes 2N-57N) et des ALAT a 4N (2N- 44N). Ces patients avec cytolyse avaient un IMC inferieur (P Conclusion La cytolyse hepatique est retrouvee pres d’une fois sur 2 dans l’AM au cours des denutritions severes. Quatre facteurs de risque ont pu etre identifies : âge jeune, homme, IMC bas et forme restrictive pure de maladie. L’evolution est le plus souvent benigne mais peut etre plus severe dans moins de 5 % des cas. Les facteurs de risque d’une evolution defavorable restent a identifier.

Apres une hepatite aigue C, une guerison survient spontanement dans 25 % des cas ; l’ARN plasmatique du VHC disparait dans les 6 premiers mois. La persistance de la viremie VHC apres 6 mois traduit le passage a la chronicite. De rares cas de guerison spontanee d’hepatites chroniques C ont ete decrits. Cas cliniques Nous en rapportons 4 cas chez des patients co-infectes par le VIH et le VHC. Il s’agit de 3 femmes et 1 homme d’âge moyen 42 ans, tous anciens usagers de drogue par voie veineuse qui avaient arrete la toxicomanie au profit d’une consommation importante d’alcool. L’infection VIH etait connue depuis en moyenne 13 annees, la serologie VHC positive etait connue depuis en moyenne 7 annees (genotype 4 deux patients, genotype 1 et 3 un patient chacun, charge virale VHC moyenne = 4,87 log). Chaque patient a eu plusieurs PCR VHC positives (2 a 4) accompagnees de transaminases elevees (moyenne 2 × N). La PCR est ensuite devenue negative jusqu’a ce jour (moyenne 4 determinations, recul moyen = 3 ans). Ces 4 guerisons ont ete observees apres mise sous tritherapie antiretrovirale (50 mois en moyenne). Lors de la negativation de la PCR VHC, le gain de CD4 etait de +270/mm 3 par rapport au nadir. Les 4 patients etaient devenus abstinents d’alcool depuis quelques mois. Discussion La guerison spontanee de l’hepatite chronique C apres restauration immunitaire et arret de l’alcool merite d’etre recherchee. Cette constatation plaide pour la mise sous tritherapie antiretrovirale et pour la promotion du sevrage alcoolique avant decision du traitement de l’hepatite C chez les patients co-infectes VIH/VHC.

Dans les pays en developpement, l’acces aux anti-retroviraux pour les patients infectes par le VIH est en constante progression. La malnutrition y est aussi tres frequente et represente une autre cause d’immunodeficience acquise. Objectif Cette etude avant/apres a evalue l’impact d’un appui nutritionnel standardise (ANS ; type blanket feeding) associe a une tritherapie anti-retrovirale (HAART) chez des patients infectes par le VIH a Niamey, Niger. Methode Le suivi clinico-biologique pendant 6 mois de 64 patients recevant l’ANS associe a une HAART, a ete compare a celui de 131 patients ayant seulement recu une HAART l’annee precedente. Resultats Dans le groupe recevant l’ANS, 3 patients decedaient contre 15 dans le groupe temoin (Ratio de Mortalite = 0,30 [0,05 ; 1,0]) ; la persistance d’infections opportunistes non resolutives etait reduite RR = 0,31 [0,11 ; 0,87] ; l’augmentation des lymphocytes T CD4+ etait 1,6 fois plus importante (p Conclusion Cette etude montrait un impact favorable de l’ANS des six mois de supplementation, associe a une HAART chez des patients infectes par le VIH dans un pays en developpement. L’impact etait observe sur les plans clinique, immunologique et sur l’observance. L’amelioration de l’observance etait le meilleur signe de la portee sociale de l’ANS associee a la HAART. L’ANS devrait etre propose le plus largement possible pour les patients infectes par le VIH dans les pays en developpement.
