Satisfaction with care in HIV-infected patients treated with long-term follow-up antiretroviral therapy: the role of social vulnerability.

The aim of this study was to determine factors associated with complete satisfaction with the care provided (satisfaction with physicians and satisfaction with services and organization) among HIV-infected patients followed up in the French ANRS CO8 APROCO-COPILOTE cohort. Analyses focused on cross-sectional data collected during the ninth year of cohort follow-up. Satisfaction with care, sociodemographic characteristics, and behavioral data were collected using self-administered questionnaires, while clinical data were derived from medical records. Complete satisfaction with care was defined as being 100% satisfied. Two logistic regression models were used to identify predictors of (1) complete satisfaction with physicians (n=404) and (2) complete satisfaction with services and organization (n=396). Sixteen percent of patients were completely satisfied with physicians, while 15.9% were completely satisfied with services and organization. Being older and reporting fewer discomforting antiretroviral therapy (ART) side effects were factors independently associated with complete satisfaction with both physicians and services and organization. Strong support from friends and absence of hepatitis C (HCV) co-infection were independently associated with complete satisfaction with physicians, while strong support from one's family and comfortable housing conditions were independently associated with complete satisfaction with services and organization. Even after nine years of follow-up, social vulnerabilities still strongly influence HIV-infected patients' interactions with the health care system. Day-to-day experience with the disease, including perceived treatment side effects, appears to play a key role in the quality of these interactions. More attention should be given to patient satisfaction, especially for socially vulnerable patients, in order to avoid potentially detrimental consequences such as poor adherence to ART.

Hepatitis C virus (HCV) protease variability and anti-HCV protease inhibitor resistance in HIV/HCV-coinfected patients.

OBJECTIVES: Data on the natural selection of isolates harbouring mutations within the NS3 protease, conferring resistance to hepatitis C virus (HCV) protease inhibitors (PIs), are limited for HIV/HCV-coinfected patients. The aim of this study was to describe the natural prevalence of mutations conferring resistance to HCV PIs in HIV/HCV-coinfected patients compared with HCV-monoinfected patients. METHODS: The natural prevalences of HCV PI resistance mutations in 120 sequences from HIV/HCV-coinfected patients (58 genotype 1a, 18 genotype 1b and 44 genotype 4) and 501 sequences from HCV-monoinfected patients (476 genotype 1 and 25 genotype 4), retrieved from GenBank as a control group, were compared. RESULTS: Of 76 sequences from HIV/HCV genotype 1-coinfected patients, six (7.9%) showed amino acid substitutions associated with HCV PI resistance (V36L, n=1; V36M, n=2; T54S, n=2; R155K, n=1). In 31 of 476 (6.5%) HCV genotype 1 sequences retrieved from the GenBank database, HCV PI resistance mutations were found. The difference was not statistically significant (P=0.6). All of the sequences from HIV/HCV genotype 4-coinfected patients and those retrieved from the GenBank database had amino acid changes at position 36 (V36L). CONCLUSION: Our study suggests that the natural prevalence of strains resistant to HCV PIs does not differ between HCV-monoinfected and HIV/HCV-coinfected patients. Further studies on larger cohorts are needed to confirm these findings and to evaluate the impact of these mutations in clinical practice.

[A case of severe community acquired pneumonia and non-respiratory illness induced by Influenza A]. / Une grippe exceptionnelle.

BACKGROUND: Severe community acquired pneumonia is a common cause of acute respiratory failure. The influenza virus itself can cause a severe pneumonia and non-respiratory illness. CASE REPORT: A physician developed an acute respiratory failure associated with hemolytic anemia, acute renal failure, and myocarditis. Influenza A infection was diagnosed by screening for antibodies (complement fixation, ELISA Ig A). DISCUSSION: Fulminant influenza pneumonia is a rare clinical presentation of influenza infection and usually has a severe clinical course. Influenza infection is also associated with myositis, myocarditis, acute renal failure, encephalopathy, and hemolytic anemia. Rapid laboratary diagnosis can be made by PCR or immunofluorescence applied directly to respiratory specimens. Antiviral treatment did not prove its efficacy in fulminant Influenza. This case report is an opportunity to stress the importance of seroprophylaxis by parenteral vaccination in exposed occupations.

[Clinical, microbiological, and therapeutic aspects of Nocardia sp. infections in the Bordeaux hospital from 1993 to 2003]. / Aspects cliniques, microbiologiques et thérapeutiques des infections à Nocardia sp. au centre hospitalier universitaire de Bordeaux entre 1993 et 2003.

OBJECTIVE: Our goal was to describe the epidemiological, clinical, and microbiological characteristics of nocardiosis in the Bordeaux teaching hospital, between January 1, 1993 and December 31, 2003. DESIGNS: The retrospective study included patients examined between January 1, 1993 and December 31, 2003 in whom a Nocardia bacterium had been identified from a biological sample. RESULTS: Twenty-four out of 30 Nocardia sp. strains identified during the study period were classified as colonizing strains. 19 patients presented with risk factors for nocardiosis. Nocardia asteroïdes were found in 22 samples, mainly from pulmonary samples. 11 cases of infection due to Nocardia sp. were reported during the study period. Immunosuppression was reported in 7 cases. The clinical forms were not specific. The species incriminated belonged to the N. asteroïdes complex in 8 cases. Treatment consisted in a combination of 2 or 3 molecules including cotrimoxazole for an average duration of 9 months. 9 patients recovered. CONCLUSIONS: The variability of clinical presentation and the lack of standard identification methods delayed the diagnostic. The treatment is not well defined. Clinical strains should be reported to the reference laboratory and prospective studies are necessary.

An imported case of canine rabies in Aquitaine: investigation and management of the contacts at risk, August 2004-March 2005.

In August 2004, a case of rabies was diagnosed in a puppy that had been illegally imported from Morocco to Bordeaux (France). Because a great number of people and animals were thought to have come into contact with the puppy, extensive tracing measures were implemented, and an international alert was launched to trace and treat the contacts at risk. One hundred and eighty seven people received post-exposure treatment, eight of whom also received serovaccination, and 57 animals known to have been exposed to the puppy were tested. Six months after the death of the rabid animal, none of the people treated showed any signs of rabies, nor was any secondary animal case reported. The management of this crisis highlights the importance of the role of a rapid alert system at European level. Strict application of sanitary control regulations is essential for animals introduced into EU countries, and all necessary information must be made available to EU residents travelling to rabies enzootic areas.

Short-term effect of red wine (consumed during meals) on insulin requirement and glucose tolerance in diabetic patients.

OBJECTIVE: To determine the effect of wine on insulin requirement or glucose tolerance. RESEARCH DESIGN AND METHODS: Five men with insulin-treated diabetes and 10 men with non-insulin-treated diabetes ate the same lunch with the same volume of either water or red wine (2 glasses). Insulin requirement was determined with an artificial pancreas (Biostator). Glucose tolerance was evaluated from the postprandial glycemic level. RESULTS: There was no significant difference in insulin requirement determined with an artificial pancreas in the insulin-treated patients after the two meals (31.5 +/- 4.21 U with water and 31.8 +/- 4.3 U with wine). Glucose tolerance in the non-insulin-treated patients was lower after the meal with wine. CONCLUSIONS: Moderate prandial wine consumption has no adverse effect on the glycemic control of diabetic patients. Thus, it appears unnecessary to proscribe the consumption of red wine in moderation with meals to diabetic patients. Wine contains tannins and phytates that can explain its action.

Tuberculosis and HIV infection: a cohort study of incidence and susceptibility to antituberculous drugs, Bordeaux, 1985-1993. Groupe d'Epidémiologie Clinique du SIDA en Aquitaine.

OBJECTIVES: To assess the temporal trends in incidence of tuberculosis (TB) in HIV-infected patients, to evaluate the impact of pulmonary TB on the Centers for Disease Control and Prevention (CDC) 1993 AIDS case definition and to assess the frequency of Mycobacterium tuberculosis strain resistance. DESIGN: A retrospective study within a cohort. SETTING: The Bordeaux University Hospital and three general hospitals in Aquitaine, southwest France. SUBJECTS: Since 1985, HIV-infected in- and outpatients aged > 13 years have been included in the Aquitaine cohort. Reported cases of pulmonary and extrapulmonary TB were investigated and records cross-referenced with the files of the TB reference laboratory. RESULTS: As of 30 June 1993, the Aquitaine cohort (3119 patients) accounted for 6409 person-years (PY) of follow-up. TB was diagnosed in 139 patients (average annual incidence, 2.17 per 100 PY) of whom 79 had bacteriological diagnosis, 13 histological diagnosis and 47 clinical and/or radiological diagnosis. Extrapulmonary TB accounted for 40% of the cases. Intravenous drug use was more frequent in the group who developed TB (50%) than in the rest of the cohort (40%) (P = 0.009). There was an increase in the incidence rate of TB in the cohort between 1985 (0.45 per 100 PY) and 1989 (2.67 per 100 PY) and a stabilization around 1.5-2.0 per 100 PY until 1993. Pulmonary TB was estimated to increase the AIDS cumulative incidence by 0.4% when performing a simulation with the 1993 AIDS case definition. Single drug resistance was documented in 3.4% of the cases and a multiple drug resistance in 5.1%. CONCLUSION: TB incidence has stabilized since 1990 in the Aquitaine cohort with a limited increase of the number of AIDS cases (1993 CDC criteria). Drug resistance was rare.

Women and HIV infection: a cohort study of 483 HIV-infected women in Bordeaux, France, 1985-1991. The Groupe d'Epidémiologie Clinique du SIDA en Aquitaine.

OBJECTIVES: To study the epidemiological trends, clinical patterns, evolution and prognosis of HIV infection in women. DESIGN: Cohort study of 1816 HIV-infected patients. RESULTS: Up to 1 January 1991, 483 (26.6%) of the patients reported to the Groupe d'Epidemiologie Clinique du SIDA en Aquitaine surveillance system were women. The male-to-female ratio has decreased progressively (3.4:1 in 1985; 2.7:1 in 1990) over time. Fifty per cent of HIV-infected women are or have been intravenous drug users (IVDU). The proportion of heterosexually acquired HIV infection increased from 11.6 to 34.6% over the last 5 years; 46.9% of the women infected through heterosexual intercourse reported sexual contacts with male IVDU. Excluding Kaposi's sarcoma, no significant difference was observed between men and women in the overall distribution of AIDS-defining events. The observed trend of a slower progression to AIDS in women, compared with men, disappeared when controlling for prognostic variables. However, female sex significantly enhanced survival after AIDS diagnosis in multivariate analysis (relative risk, 2.7; 95% confidence interval, 1.1-6.2). CONCLUSION: Early diagnosis of HIV infection in female patients and prevention of HIV infection among women is now a priority for public health interventions, both in industrialized and in developing countries.

Impact of protease inhibitors on intrahepatic hepatitis C virus viral load.

During chronic hepatitis C, hepatitis C virus (HCV) load in plasma was shown to be higher in HIV-co-infected than in immunocompetent patients [1]. The reason for this increased HCV replication is not known. It may be as a result of HIV-induced immune deficiency [2], although some authors did not find any correlation with the CD4 cell count [3]. A direct interaction between HCV and HIV was also hypothesized [4]. Protease inhibitors (PI) used in highly active antiretroviral therapy (HAART) have no HCV reduction effect during the first months of treatment [5-8]. However, a decrease in HCV plasma load was recently described in patients treated with HAART for a year [9,10]. We therefore investigated the potential impact of HAART on intrahepatic HCV load.

Detection of JC virus DNA in the peripheral blood leukocytes of HIV-infected patients.

OBJECTIVES: To assess whether JC virus (JCV) DNA is frequently harboured by peripheral blood leukocytes (PBL) in HIV-positive patients, before the onset of progressive multifocal leukoencephalopathy (PML). DESIGN: The polyomavirus JCV induces PML in immunocompromised persons and particularly AIDS patients. Leukocytes may play a central part in the onset of PML, but their precise role in JCV latency and reactivation still remains hypothetical. The controversial presence of JCV DNA in PBL has been, until now, investigated only among small groups of patients. We therefore studied 157 HIV-positive persons and compared them with 65 HIV-negative immunocompromised patients. METHODS: DNA was extracted from PBL. The presence of JCV DNA was demonstrated by the polymerase chain reaction (PCR) alone or combined with a molecular hybridization assay. RESULTS. The presence of JCV DNA was ascertained by PCR and hybridization in 28.9% of 135 HIV-infected persons at all stages of HIV infection and only 16.4% of 61 HIV-negative immunocompromised patients. No correlation could be drawn between the detection of JCV DNA and the clinical or biological status of the HIV-positive patients. CONCLUSIONS: JCV DNA is detectable in the PBL of 28.9% of HIV-infected persons, even in the early stages of infection. JCV is more seldomly amplified in HIV-negative immunocompromised patients. Further work is in progress to determine the prognostic value of the presence of JCV DNA in the blood of HIV-positive patients.

Increase in CD3+ CD4- T lymphocytes in patients with AIDS and disseminated Mycobacterium avium-intracellulare complex infection: a prospective study. GECSA. Groupe d'Epidemiologie Clinique du SIDA en Aquitaine.

In a retrospective study, an increase in double-negative (CD3+ CD4- CD8-) (DN) T lymphocytes has been shown to be an independent predictor of disseminated Mycobacterium avium complex (D.MAC) infection in patients with less than 100 CD4+ T cells per mm3. To better characterize this cell expansion, a prospective study was designed. From July 1995 to April 1997, 206 HIV-infected patients with less than 100 CD4+ T cells per mm3 were prospectively followed up and immunophenotyped. The median followup was 1.1 year (+/-0.5 year), and 14 new D.MAC infections were diagnosed among 84 first AIDS-defining events. In univariate and multivariate analyses, D.MAC infections were the only opportunistic infection with a significant increase in DN T-cell percentage (median = 6.6; range = 1.7 to 24.5, P = 0.004) compared with patients without any opportunistic infection. This alteration in T-lymphocyte count could constitute a predictor for D.MAC infection in clinical practice.

Intraperitoneal injection of technetium-99m sulfur colloid in visualization of a peritoneo-vaginalis connection.

Ten minutes after an intraperitoneal infusion of Tc-99m sulfur colloid, a gamma camera was used to obtain anterior abdominal views. This visualized a peritoneoscrotal communication in an 80-yr-old patient. He had developed extensive edema of the genitals and lower limbs after about 6 wk of continuous ambulatory peritoneal dialysis. At operation the communication was confirmed and closed. A repeat test verified the success of operation.

Course of specific T lymphocyte cytotoxicity, plasma and cellular viral loads, and neutralizing antibody titers in 17 recently seroconverted HIV type 1-infected patients.

Relationships were sought between specific anti-HIV cytotoxic T lymphocyte (CTL) responses (against structural and regulatory proteins of the HIV-1 LAI isolate) and plasma and cellular viral loads (VLs) in 17 recently HIV-1-infected patients including 3 displaying asymptomatic primary infection (PI) followed up for 12 months. Plasma VL was correlated directly with CD8 counts and inversely with CD4 counts. Cytotoxic reactions were observed in all patients and directed mainly against structural proteins. The earliest CTL responses were against Gag and Env proteins detected in 87 and 75% of the subjects, respectively, within the first month following PI. Anti-Env and Gag cytotoxic responses were inversely correlated with the plasma VL. Reactions against the pol gene products were thought to be either less involved in or less efficient for the initial decrease of viremia. Responses against regulatory gene products were weak and variable, apart from Nef, which was recognized by half of the subjects. Neutralizing antibodies were not detected before month 3, and were found only in six patients at subsequent times. Two of three patients with asymptomatic PI had a low viral burden and either a delayed response or one limited to a few protein CTL responses, suggesting that the magnitude of the CTL response depends on the initial plasma VL. The third patient displayed viral and CTL parameters identical to those of the patients with symptomatic PI. However, two subjects with symptomatic PI exhibited similarly low plasma VL and moderate CTL responses. Overall, the results suggest that the CTL response may not be the sole factor controlling viremia.

Pharmacokinetics of intravenous and intraperitoneal ceftazidime in chronic ambulatory peritoneal dialysis.

The pharmacokinetics of ceftazidime have been investigated in eight patients with chronic renal failure undergoing continuous ambulatory peritoneal dialysis. Each subject was given ceftazidime 1 g intravenously and 1 g intraperitoneally at an interval of 1 week. Ceftazidime was assayed by high-pressure liquid chromatography. After intravenous administration, the pharmacokinetic parameters of ceftazidime were: elimination plasma half-life (t1/2 beta) = 24.6 +/- 4.6 hours; apparent volume of distribution (V(area)): 0.37 +/- 0.09 1/kg, total plasma clearance (CL): 11.9 +/- 3.3 mL/minute, peritoneal clearance (CLp): 1.7 +/- 0.3 mL/minute. Over 72 hours, only 15.6 +/- 4.7% of the dose was eliminated by the peritoneal route. After intraperitoneal administration, ceftazidime appeared in the plasma rapidly, and the peak plasma concentration of 24.5 +/- 5.2 mg/L was achieved at the fourth hour; the elimination half-life (t1/2ke) was 20.8 +/- 1.7 hours. The absorption of ceftazidime from the peritoneal space was 74.1 +/- 7.4%. These data suggest that ceftazidime has bidirectional exchange characteristics through the peritoneal membrane. A single 1-g intraperitoneal dose led to serum and dialysate concentrations of ceftazidime above the minimum concentrations for susceptible pathogen germs for 24 hours.

Emphysematous cystitis.

We present a case of emphysematous cystitis in a diabetic patient with a poor glycemic control in the context of alcoholic chronic pancreatitis. A 62-year-old woman was admitted to the emergency department after being found on floor with confusion and vomiting. The clinical examination was unremarkable except she was undernourished, agitated and presented an hepatomegaly. Urine contained 5.104 leukocytes/mm3 and culture grew Escherichia coli, 10(7) Colony Forming Unit/ml. Abdominal plain film showed gas shadows along the wall of urinary bladder. CT scan of the pelvis confirmed the presence of gas, and diffuse thickening of the urinary bladder wall. A Foley catheter was placed and the patient was treated with antibiotics for 6 weeks. She was also treated with insulin, rehydratation, vitamin B1 and B6, and pancreatic enzyme replacement. Emphysematous cystitis is defined by the presence of gas in the urinary bladder wall. It complicates urinary tract infections especially in diabetic patients but other disabled general medical conditions may be present. Because this relatively uncommon disease may present with fairly nonspecific findings, the diagnosis is often made incidentally on X-rays. However, as early diagnosis and treatment improve the outcome, a high index of suspicion for unusual presentations is warranted. Every diabetic patient with a urinary tract infection who seems to be severely ill should have an abdominal X-ray as a minimal screening tool to detect emphysematous complications.

Hepatitis B exacerbation with a precore mutant virus following withdrawal of lamivudine in a human immunodeficiency virus-infected patient.

Chronic active hepatitis B exacerbations have been reported following development of resistance to or withdrawal of lamivudine in HIV-infected patients. A 38-year-old woman with HIV and chronic HBV infections was hospitalized because of acute hepatitis. The occurrence of cytolysis with replication of HBV 2 months after withdrawing lamivudine suggests that our patient experienced a severe reactivation of HBV infection due to the modification of her treatment. Sequencing of the HBV precore region showed the strain to be a mutant. We conclude that lamivudine should not be stopped in HIV- and HBV-infected patients, but could be continued at the dose of 100mg/day as used in isolated HBV infection.

Incidence of cytomegalovirus disease in the Aquitaine cohort of HIV-infected patients: a retrospective survey, 1987-1993. Groupe d'Epidémilogie Clinique du SIDA en Aquitaine (GECSA).

We estimated the incidence of the first episodes of cytomegalovirus (CMV) disease in the Aquitaine cohort of HIV-infected subjects, south-western France. Cases were retrospectively investigated using standardized definition criteria. Retinitis was confirmed by an ophthalmologist. Gastro-intestinal lesions were confirmed histologically. Encephalitis was histologically confirmed; it was considered possible if TDM or magnetic resonance imaging (MRI) and symptomatology suggested this diagnosis. Pneumopathy was probable in case of hypoxemia, interstitial X-Ray images and response to CMV treatment; it was confirmed if intranuclear inclusions were identified on biopsy or brushing specimen. In the cohort (n = 3525) followed for an average of 46 months, 158 patients had a first episode of CMV disease. The cumulative incidence was 4.5% and the incidence rate (IR) 1.2 per 100 person-years. The IR was higher for homosexuals (2.0) than for heterosexuals (1.0) and intravenous drug users (0.5). Retinitis was the most frequent site (90 cases), followed by digestive system (40), lung (three confirmed and 17 probable) and central nervous system (eight confirmed and three possible). Sixty-eight percent of the patients were at the AIDS stage when CMV disease was diagnosed, with a mean CD4 count of 42/mm3. The cumulative probability of developing CMV disease 2 years after falling below 200 CD4 lymphocytes/mm3 was 8.0%. Retinitis is by far the most common site for CMV disease. Homosexual transmission of HIV, clinical AIDS and low CD4 count are associated with the occurrence of the first episode of CMV disease.

Pathologic correlations between ocular and cerebral lesions in 36 AIDS patients.

The eyes and brain have rarely been studied simultaneously in AIDS patients. We have examined both the eyes and brain of 36 patients autopsied these past 3 years. Ten cases had concomitant involvement of eyes and brain by the same pathology: cryptococcus neoformans in 1, aspergillus in another, cytomegalovirus (CMV) infection in 5, and B cell lymphomas in 2 (1 patient had the last 2 disorders associated). One patient presented pericapillary microhemorrhages in the retina of the left ocular globe as well as in the right occipital lobe. Six other patients had isolated CMV retinopathy and 4 others had B cell cerebral lymphomas. Eleven patients with foci of cerebral toxoplasmosis did not have visible cysts of toxoplasma gondii in their retina, in agreement with the other series devoted to the concomitant study of the eyes and brain in AIDS patients. On the other hand, their simultaneous involvement in an AIDS patient must first point to CMV infection.

[Hepatic manifestations of psittacosis]. / Les manifestations hépatiques de la psittacose.

A moderate increase in transaminases and alkaline phosphatase serum concentrations was observed in 14 of 32 patients with psittacosis (antibodies anti-Chlamydia psittaci greater than or equal to 1/40 with the complement fixation test). Clinical manifestations were present in 4 patients (hepatomegaly in 4 cases; jaundice in one case). In one patient, histological examination of a liver specimen showed granuloma. In 13 patients treated with tetracycline or macrolides, the outcome was favorable. One patient recovered spontaneously. In comparison with the group of 18 patients without hepatic involvement, there was no difference pertaining to epidemiological, clinical, or serological findings. Equally, there was no difference in the course of the disease.
