[Follow-up with the assistance of TB-info software of 208 tuberculosis patients who were treated in 2004]. / Intérêt de l'utilisation du logiciel TB-info pour le suivi des patients mis sous traitement antituberculeux: analyse des 208 patients de la cohorte 2004.

INTRODUCTION: The impact of the TB-info software was assessed on the care of patients treated with antituberculosis regimen (ATT). METHODS: Cohort study of patients with tuberculosis who received an ATT in 2004 in two hospitals and five medical centres in Paris. Follow-up was implemented with the TB-info software. Data were compared to those of the 1999-2003 cohort. RESULTS: Two hundred and nine ATT were initiated in 2004, with a mean duration of 7.2 months. Demographic and clinical data reflected this population precariousness: 79% were foreign-born, 25% lived in institutions and half of them had no or unusual health insurance. Compared to the previous cohort, viral co-infections were tested in more than 80% cases and showed association with HIV, HBV or HCV in 11, 10 and 5% of the patients, respectively. Twenty-one patients were lost for follow-up (11%) and 76% of the smear-positive pulmonary tuberculosis therapies were declared successful but only 34% were declared cured with the WHO criteria. CONCLUSION: Analysis of the data obtained with TB-info software showed an improvement of tuberculosis patients care with more co-infection tested and less lost for follow-up. These results confirm the usefulness of this software for patients care and assessment of physicians practice in France.

Tuberculosis in European cities: establishment of a patient monitoring system over 10 years in Paris, France.

BACKGROUND: Tuberculosis (TB) is a persistent public health problem in European cities. France has been unable to report on treatment outcomes until now, and it is not known whether the World Health Organization (WHO) target cure rate of 85% has been met. METHODS: All patients placed under treatment in four hospitals and five out-patient Social Medical Centres in Paris were followed up between 1996 and 2005. Patient monitoring and evaluation were performed using a new software programme, TB-INFO. RESULTS: In a cohort of 1127 patients, 76% had pulmonary TB, of whom 39% were smear-positive, 81% were foreign-born and 9.3% were human immunodeficiency virus positive. At the end of the follow-up, 16% were cured and 54% had completed treatment. Among the 1118 non-multidrug-resistant patients, these percentages were 17% and 46%, respectively, for smear-positive pulmonary patients. Some patients died (1.9%) or failed treatment (0.1%), but many more defaulted (20.5%) as they interrupted treatment (1.5%), were lost to follow-up (19.5%) or were transferred out (7.9%). CONCLUSIONS: This 10-year follow-up of TB patients, managed with TB-INFO software, shows that a patient monitoring system can be implemented in France, providing essential information. Treatment success in this cohort of patients was far below the WHO target.

HIV infection and tobacco smoking behaviour: prospects for prevention? ANRS CO3 Aquitaine Cohort, 2002.

OBJECTIVE: To provide up-to-date and covariate-specific estimates on tobacco smoking prevalence in a representative cohort of French human immunodeficiency virus (HIV) 1 infected patients in 2002. DESIGN: We conducted a cross-sectional analysis of the Aquitaine Cohort of HIV-infected patients. A logistic regression model was used to estimate associations between regular tobacco smoking and sex, age, HIV transmission categories, duration and immuno-virological status of HIV infection and duration of antiretroviral therapy. Smoking prevalence estimates were compared with the general French population values after stratification on age and sex. RESULTS: Among 2036 patients included in the analysis, 51% were regular smokers (95%CI 49-53). Smoking prevalence was significantly higher with younger age (OR 1.7 among those < or = 45 years of age), among injecting drug users (OR 4.3), among those whose infection was not controlled (OR 1.2) and those whose HIV infection had been diagnosed for > or = 5 years (OR 1.5). The main difference with the general population was the peak smoking prevalence among HIV-positive patients infected through injecting drug use. CONCLUSIONS: HIV-infected patients are highly exposed to tobacco smoking, which is implicated in multiple conditions occurring in the course of HIV infection. Adapted smoking cessation programmes should become one of the priorities of the medical care of HIV-infected individuals.

[Portal vein thrombosis in HIV-infected patients: report of four cases]. / Thrombose portale chez des patients infectés par le virus de l'immunodéficience humaine: à propos de quatre observations.

Portal vein thrombosis (PVT) seems rare among HIV infected patients. Even though, the report of such cases is of great interest because it may help to determine the factors of occurrence. We describe cases of PVT in 4 HIV-infected men, aged 32 - 64. Two of them were co-infected with hepatitis C virus (HCV). The four patients had a history of disseminated mycobacterial infection (one case of tuberculosis, 3 cases of mycobacterium avium complex infection) with abdominal lymphadenitis. Despite HAART, their immunodeficiency was profound (CD4: 65 to 216/mm(3)). At the time of diagnosis, two patients were treated with protease-inhibitor containing regimen: indinavir (one case), ritonavir-saquinavir (one case). PVT was revealed by haematemesis (one case), abdominal pain (ome case), anasarca (2 cases). In three patients, the diagnosis of PVT was confirmed by imagery (echo-doppler or angio- RMI), and for the last patient, PVT was found during the transjugular intrahepatic portosystemic shunt setup. A low level of C protein was diagnosed in one case. Cirrhosis was not found in HIV-HCV co-infected patients. Two patients died early after diagnosis, one patient died 3 years after the onset of symptoms. Various factors may cause the development of a PVT in HIV infected patient. Serious immunodeficiency, opportunistic infections such as tuberculosis and mycobacterium avium complex related infection with abdominal lymphadenitis can further the development of PVT. Protease-inhibitor might have facilitated the process. Due to the severe prognosis of advanced cases, early evocation of diagnosis is needed.

[Efficacy and safety of pegylated-interferon plus ribavirin in HIV-infected patients co-infected with hepatitis C virus in clinical practice: a 32 cases observational follow-up]. / Efficacité et tolérance de l'association interféron pégylé-ribavirine chez les patients co-infectés VIH-VHC en pratique clinique: étude observationnelle de 32 patients.

OBJECTIVE: To describe efficacy and safety in clinical practice of pegylated interferon plus ribavirin (INFpeg-Riba) in the treatment of hepatitis C viral infection (HCV) in HIV infected patients. METHODS: Monocentric retrospective study with inclusion of all patients who received at least once INFpeg-Riba before April 1st 2003. All patients were followed up to six months after the end of HCV therapy. RESULTS: Thirty two HIV-positive patients (23 men and 9 women) with chronic hepatitis C treated by INFpeg-Riba were included. The mean age was 43 years. Fourteen patients carried HCV genotype 2 or 3 (43 %) and 18 patients carried genotype 1 or 4 (57%). The Metavir score of fibrosis showed fibrosis F1 (N =3), F2 (N =14), F3 (N =7) and F4 - cirrhosis (N =8). Twenty six patients (81%) were naive for anti hepatitis C drugs. Thirty one per cent of patients were at AIDS stage and 84% were receiving antiretroviral drugs. The mean CD4 cell count was 469 /ml and the plasma RNA HIV was less than 50 copies /ml in 57% of the cases. Adverse events leading to reduction of dose of drugs occurred in 40% and adverse events leading to discontinuation treatment occurred in 12%. A decline of CD4 cell count <200 CD4/ml was observed in 15%. Clearance of HCV-RNA in end of treatment was seen in 46 % and sustained virological response in 34 %. The main predictors of sustained virological response were HCV genotype 2 or 3 (P =0.04) and plasma HIV RNA less than 50 copies/ml (P =0.001). The predictive value of good virological response of a CD4 cell count >350/ml before treatment was very near the statistical significancy (p =0.07). CONCLUSIONS: The efficacy of pegylated interferon plus ribavirin in HIV-HCV co-infected patients is disappointing mainly due to a poor tolerance. In addition to HCV genotype, plasma HIV RNA level and CD4 cell count were essential to predict INFpeg-Riba response and should be taken into account in the process leading to the initiation of such therapy in HIV-HCV co-infected patients.

Acute liver failure as initial manifestation of low-grade non-Hodgkin's lymphoma transformation into large-cell lymphoma.

Acute liver failure as an initial manifestation of primary non-Hodgkin's lymphoma is a rare phenomenon with a grim prognosis. We report for the first time on a patient with a history of follicular lymphoma in complete remission, presenting fulminant liver failure due to massive liver infiltration by transformed lymphoma cells and portal vein thrombosis, as an initial manifestation of transformation into large-cell lymphoma.

Intramedullary abscess resulting from disseminated cryptococcosis despite immune restoration in a patient with AIDS.

We report on a case of cryptococcal intramedullary abscess, which occurred three years after a disseminated cryptococcosis and two years after a lymph node cryptococcal recurrence in a HIV-infected patient who exhibited a long-standing immune restoration. At the time of diagnosis, CD4(+) lymphocyte-count was 640x10(6)/l and HIV viral load was undetectable. Spinal involvement is rare during cryptococcosis of the central nervous system. As far as we are aware, there is only one case of proven intramedullary cryptococcal abscess reported in the literature and this case is then the second one. The significant and sustained increase in CD4 count following effective antiretroviral therapy was probably associated with only a partial immune restitution that did not allow to avoid the occurrence of the cryptococcal medullar abscess. Finally, this case raises the question of when to stop secondary prophylaxis of cryptococcal disease after increase in CD4 cell count under antiretroviral therapy.

[Hereditary multiple exostoses after 40 years of development: a case report]. / Maladie des exostoses multiples après 40 ans d'évolution: à propos d'un cas.

INTRODUCTION: Hereditary multiple exostoses is an autosomal dominant skeletal disorder with genetic heterogeneity and an estimated prevalence of 1/50,000 in western countries. Malignant degeneration is a rare (about 2%) but classical complication in patients with hereditary multiple exostoses. At least 3 loci identified as EXT 1, EXT 2 and EXT 3 are involved in this skeletal disease. EXEGESIS: The case of a 45-year old man is described with 15 years follow-up after resection of a well-differentiated chondrosarcoma (grade I), which arose from a right posterior pelvic exostosis. The observed radiological lesions remained relatively stable until now. The genetic mutation which is responsible for the disease was determined at the locus EXT 1. CONCLUSION: The present case report illustrates the natural history of hereditary multiple exostoses, especially since the patient underwent a malignant degeneration which could be resected without recurrence. The results of the genetic analysis contributed to the understanding of the pathophysiology of the disease.

Impact of pain in health related quality of life of patients with systemic sclerosis.

OBJECTIVES: Systemic sclerosis (SSc) has an heterogenous clinical pattern, with variable organ involvement and degrees of severity. Like in other rheumatic diseases, the self-questionnaires have been used to evaluate SSc globally. The aim of the study is as to evaluate the quality of life (QoL) in patients with either diffuse or limited SSc, and to examine the impact of pain on the QoL scores. METHODS: Patients with SSc, either diffuse or limited SSc, were included in a cross-sectional study. The QoL was evaluated with the short-form 36 (SF-36) and the functional repercussion with the SSc-modified Health Assessment Questionnaire (S-HAQ). RESULTS: A total of 89 patients (67 with diffuse and 22 with limited SSc) were included. The SF-36 score values were lower in SSc patients than those reported in the general population. The physical component scores (PCS) of the SF-36 was significantly worse in diffuse compared with limited SSc (P < 0.05). The PCS was significantly negatively related to the number of clinical manifestations (ANOVA, P < 0.0001). The mental component score (MCS) was not influenced by the type of SSc or the number of clinical manifestations presented by the patient. The QoL of SSc patients was highly correlated with pain (R = 0.69) and disability (R = 0.70). Interestingly, the QoL of SSc patients was only slightly correlated with cutaneous (R = 0.42) and pulmonary involvement (R = 0.57). CONCLUSION: The QoL of patients with SSc is strongly influenced by the type of SSc, the burden of clinical manifestations, the functional disability and by the pain, whatever its cause. The treatment of pain should be considered as priority to improve the QoL of SSc patients.
