RESUMEN

Multiple sclerosis (MS) is one of the 30 chronic conditions specifically listed by the French healthcare system as a long-term disease (affections de longue durée [ALD]) for which the main health insurance fund (Caisse nationale d'assurance maladie des travailleurs salariés [CNAMTS]) provides full (100%) coverage of healthcare costs. The CNAMTS insures 87% of the French population (52,359,912 of the 60,028,292 inhabitants). The objectives of this study were to evaluate the direct and indirect medical costs of MS among the entire population insured by the CNAMTS in France in 2004. The CNAMTS provided us with access to the ALD database of patients with MS that contains different MS-related expenditures made in 2004. We calculated the overall direct and indirect cost of MS and the cost per patient and per item of expenditure. In 2004, 49,413 patients were registered on the ALD list for MS. Direct cost for MS patients was 469,719,967 €. The direct cost per patient and per year was 9,506 € with variations between regions (French administrative divisions) ranging from 10,800 € in northeastern France (Champagne-Ardenne) to 8,217 € in western France (Pays de la Loire). The different items of expenditure were treatments (44.5%), hospitalization (27.9%), nursing care (5.8%), physiotherapy (5.7%), transport (4%), biology (1.1%), and other (1.5%). During the course of the disease, the overall cost of MS increased slowly during the first 15 years (from 8,000 to 11,000 €), but dramatically the last year of life (23,410 €). The costs of immunomodulator treatments were higher during the first six years after registration on the ALD list. Conversely, physiotherapy costs increased linearly with time during the course of MS. Indirect costs were an estimated 116 million euros in 2004. A disability pension (8,918 € per patient) was perceived by 9,430 patients (19.1%) and a daily allowance (3,317 € per patient) by 9,894 patients (20%). In France, MS has an important economic impact, comparable to human immunodeficiency virus infection.

RESUMEN

BACKGROUND: Net survival, the survival that might occur if cancer was the only cause of death, is a major epidemiological indicator. Recent findings have shown that the classical methods used for the estimation of net survival from cancer registry data, referred as to "relative-survival methods," provided biased estimates. OBJECTIVES: The aim of this study was to provide, for the first time, long-term net survival rates for colorectal cancer by using a population-based digestive cancer registry. DESIGN: This study is a population-based cancer registry analysis. The recently proposed unbiased nonparametric Pohar-Perme estimator was used. PATIENTS: Overall, 14,715 colorectal cancers diagnosed between 1976 and 2005 and registered in the population-based digestive cancer registry of Burgundy (France) were included. MAIN OUTCOME MEASURES: The primary outcome measured was cancer net survival, ie, the survival that might occur if all risks of dying of other causes than cancer were removed RESULTS: : Ten-year net survival increased from 31% during the 1976 to 1985 period to 47% during the 1986 to 1995 period and then leveled out (48% during the 1996-2005 period). There was a major improvement in 10-year net survival after resection for cure and for stage I to III. It was striking for stage III cancers, for which 10-year net survival increased from 21% (1976-1985) to 49% (1996-2005). The corresponding net survivals were 70% and 87% for stage I and 49% and 65% for stage II. These trends can be related to the decrease in operative mortality, the increase in the proportion of patients resected for cure, and the improvement in stage at diagnosis. They were mainly seen between 1976 and 1995, explaining why survival leveled out after 1995. LIMITATIONS: The study was limited by its retrospective and population-based nature. CONCLUSIONS: Further improvements for colorectal cancer management can be expected from more effective treatments and from the implementation of organized cancer screening.

RESUMEN

AIM OF THE STUDY: To describe trends in survival of non-resectable metastatic colorectal cancer (MCRC) over a 34-year period in a French population-based registry taking into account major advances in medical therapy. PATIENTS AND METHODS: 3804 patients with non-resectable metastatic colorectal cancer diagnosed between 1976 and 2009 were included. Three periods (1976-96, 1997-2004 and 2005-09) were considered. RESULTS: The proportion of patients receiving chemotherapy dramatically increased from 19% to 57% between the first two periods, then increased steadily thereafter reaching 59% during the last period (p<0.001). Median relative survival increased from 5.9 months during the 1976-96 period to 10.2 months during the 1997-2004 period but, despite the availability of targeted therapies, remained at 9.5 months during the 2005-09 period. During the last study period, less than 10% of elderly patients received targeted therapies compared to more than 40% for younger patients. Their median relative survival was 5.0 months compared to 15.6 months in younger patients. CONCLUSION: There was an improvement in survival in relation with the increased use of more effective medical treatment. However, at a population-based level, patients are not all treated equally and most of them, especially the elderly, do not benefit from the most up-to-date treatment options.

RESUMEN

BACKGROUND: In France, the incidence of multiple sclerosis (MS) is not well known, and MS is one of the 30 long-term illnesses for which patients are covered for 100% of their health care costs. OBJECTIVE: To estimate the incidence of MS in France and its geographic variations. METHODS: We estimated the national rate for notification of MS to the main French health insurance system, and its confidence interval (CI), between November 2000 and October 2007, which covers 87% of the population. We analysed geographic variations using a Bayesian approach. RESULTS: Between November 2000 and October 2007, among a covered population of 52,449,871, some 28,682 individuals were registered as having MS. After age standardization according to the European population, the notification rate for MS was 6.8 per 100,000 (6.7-6.9), 9.8 (9.7-10.0) in women and 3.7 (3.6-3.8) in men. When the under-notification rate (11.5% and 29%) was taken into account, the notification rate per 100,000 inhabitants was estimated between 7.6 and 8.8. The notification rate was higher in north-eastern France, and lower on the Atlantic coast and in the Alps as well as on both sides of the Rhône River. CONCLUSIONS: This study, conducted on a representative French population, provides for the first time national estimates of MS incidence between November 2000 and October 2007.

RESUMEN

Lipomas usually extend in subcutaneous tissues and rarely may be compressive. We report a case of neck lipoma resulting in jugular vein thrombosis and pulmonary embolism in a patient treated by clozapine. Clozpine may be considered an associated risk factor for thrombosis. This case suggests that performing a regional evaluation may be particularly important when thrombophlebitis occurs.

RESUMEN

INTRODUCTION: Whipple disease is a multisystem infectious disease caused by Tropheryma whipplei. We report a case in which an initial diagnosis of sarcoidosis was changed to Whipple disease endocarditis. CASE: Based on clinical, radiographic, endoscopic and histologic findings, this 61-year-old man was diagnosed with sarcoidosis. Initial response to corticotherapy was good, but the patient required 35 mg of prednisone daily. The subsequent onset of clinical and laboratory signs of inflammation cast doubt on the diagnosis. After cardiac ultrasound revealed a mass 1 cm in diameter on the mitral valve, apparently vegetation, we diagnosed culture-negative infective endocarditis and ruled out most possible causes. PCR of a duodenal biopsy sample showed Tropheryma whipplei, thus confirming the diagnosis of Whipple disease, despite normal histological findings. After 3 weeks of intravenous gentamicin and amoxicillin treatment, oral cotrimoxazole was substituted. Follow-up transesophageal ultrasound showed no mitral vegetation. The patient, still under cotrimoxazole, has been off prednisone for 13 months and is completely asymptomatic. CONCLUSION: This case is an illustration of the difficulty in distinguishing Whipple disease from sarcoidosis in practice and of the importance of that distinction.

RESUMEN

BACKGROUND: There are common risk factors between hepatitis A virus (HAV) and human immuno deficiency virus (HIV) infections. OBJECTIVES: We tried to evaluate if HIV-infected patients could be at risk for HAV. More over, HAV could worsen prognosis of HIV infection and HAV vaccination was then to be considered. Thus we assessed the prevalence and risk factors of HAV infection in an HIV-infected population. PATIENTS AND METHODS: Seroprevalence and risk factors for HAV were studied among 154 HIV-positive patients followed in a Parisian hospital (mean age: 42 years, male patients: 70.8%, female patients: 29.2%). They were screened for HAV antibodies and answered a questionnaire on risk factors for HAV and means of HIV contamination. RESULTS: The global prevalence was 72.7% [IC95%: 65.7-79.7]. We excluded patients who were born in highly endemic areas where seroprevalence reached 60% [IC95%: 51.2-70]. The HAV seroprevalence was almost 100% in migrants from highly endemic countries and for those born before 1946. The multivariate analysis showed that risk factors were the geographic origin [OR=20.88; IC95%: 2.40-181], age [OR = 2.33; IC95%: 1.24-4.39], and hemophilia [OR = 13.78; IC95%: 1.34-141]. CONCLUSION: Our results suggest that a screening test for HAV antibodies should be performed before vaccination, especially in HIV-infected patients born after 1946 or in non-endemic countries.

RESUMEN

OBJECTIVE: To assess the clinical spectrum of peripheral multifocal choroiditis (PMC) and its association with sarcoidosis. METHODS: Thirty-seven patients examined between November 1997 and November 2001 who met all diagnostic criteria for PMC were included in this retrospective study. Patients were assessed for the following signs of sarcoidosis: typical changes on chest radiography or computed tomography; predominantly CD4 lymphocytosis in bronchoalveolar lavage fluid; elevated serum angiotensin-converting enzyme levels; elevated gallium uptake; and noncaseating granuloma on biopsy. RESULTS: Most of the patients were female (30 of 37; 81%) and white (30 of 37; 81%). Mean +/- SD age at onset was 57.5 +/- 18.7 years. Seven (19%) of the 37 patients had biopsy-proven sarcoidosis and 18 patients (49%) with presumed sarcoidosis met at least 2 of the above-mentioned criteria for sarcoidosis but had normal biopsy results. Twelve patients (32%) had an indeterminate diagnosis. Patients with presumed sarcoidosis did not differ from those with proven sarcoidosis as regards the above-mentioned criteria, except for noncaseating granuloma, implying that more than two-thirds of patients (predominantly whites) had underlying sarcoidosis. Most patients with positive gallium scintigraphy had increased mediastinal uptake, as described in sarcoidosis. Patients with underlying sarcoidosis had more severe visual impairment due to cystoid macular edema (CME). Weekly methotrexate (0.3 mg/kg) seemed to control CME. CONCLUSION: White patients with PMC should be considered to have sarcoidosis. The identification of sarcoidosis in patients with severe ocular disease can help with therapeutic choices.

RESUMEN

A link between chronic hepatitis C virus (HCV) infection and low-grade B-cell lymphomas has been suggested by epidemiological studies. Marginal zone lymphomas (MZLs) including splenic lymphomas with villous lymphocytes are among the most frequently reported subgroups in the setting of chronic HCV infection. In this study, we examined the effect of antiviral treatment in eight patients with HCV-associated MZL. We found that five out of eight patients have responded to interferon alpha and ribavirin. In some cases, hematologic responses were correlated to virologic responses. In addition, we report a case of large granular lymphocyte leukemia occurring in association with MZL and HCV, and responding to interferon and ribavirin. We suggest that there is an etiologic link between HCV and antigen-driven lymphoproliferative disorders.

RESUMEN

Concomitant human immunodeficiency virus (HIV) infection and sarcoidosis is rare. Sarcoidlike reactions could belong to the "highly active antiretroviral therapy (HAART)-induced immune restitution syndrome." We report a case of sarcoidosis beginning after 2 months of interleukin-2 (IL-2) therapy in a patient with HIV who had undetectable plasmatic viral load under HAART and we discuss possible mechanisms.
