[Organized hepatitis C screening. Results and cost of a one-year campaign in a pilot area].

OBJECTIVES: The management and monitoring process and the efficiency of targeted hepatitis C screening in the French health care system are not known. We assessed the main results and the cost of the program established in the Doubs area, where organized screening was integrated into the activities of voluntary physicians. METHODS: All biological laboratories in the area, 23% of the private general practitioners, 42% of occupational physicians, one prison health service and one health centre agreed to participate. Screening was targeted to the following risk factors: transfusion before 1991, intravenous drug use, tattooing and household contact. The prescription form specified the indication and allowed free testing. RESULTS: Among the volunteers, 58% of the general practitioners, 63% of the occupational physicians and 50% of the laboratories prescribed at least one screening test. In one year, 948 serologies were prescribed, mainly for tattooing (45%) or transfusion (28%). Only 83% of the tests were performed, with patient observance depending on age, indication and the place of prescription. Thirty-one patients were positive (4%). The cost of the campaign was 10 994 F per screened case. CONCLUSION: Mobilizing health professionals for organized screening is difficult which affects the efficiency of strategies.

[Strategies of hepatitis C screening in general practice. Results of a two-center randomized trial].

OBJECTIVES: To improve the detection of patients infected with hepatitis C virus. METHODS: A study was undertaken in the general medicine setting in two hepatitis C networks. General practitioners volunteered and received training on hepatitis C, then were randomly assigned to one of two screening strategies: group 1: general practitioners prescribed hepatitis C virus testing if the risk factors for HCV hepatitis C virus infection were identified during questioning of patients, group 2: general practitioners were helped in their screening approach by posters and leaflets on the risk factors of hepatitis C virus, available in the waiting room. RESULTS: A total of 184 general practitioners enrolled 90 from group 1 and 94 from group 2. During a 15-month-period, 617 serologies were prescribed, 323 by general practitioners in group 1 (in patients who were an average of 40 year-old) and 294 in group 2 (in patients who were an average of 44 year-old); 489 serologies (79.3%) were actually performed (261 and 228 respectively) and 25 (5.1%) tested positive (15 and 10 respectively). The number of prescribed, performed, and positive serologies did not differ from one group to the other. The motive for hepatitis C virus screening was similar in both groups and included a history of transfusion in 27% of cases, intravenous drug use in 6%, increased ALT or symptoms compatible with hepatitis in 13%, nosocomial exposure in 22%. Risk factors in the 25 patients who were hepatitis C virus positive were drug use (44%), history of transfusion before 1991 (16%), elevated ALT or symptoms (12%), others (28%). CONCLUSION: This study comparing screening strategies in general medicine, resulted in the diagnosis of hepatitis C virus infection in 5% of tested patients, regardless of the strategy. However, the fewer serologies prescribed by general practitioners (an average of 3 tests in a 15-month-period) suggests a low rate of identified risk factors in general practice, and emphasizes that other types of screening procedures should be implemented and evaluated.

[Do general practitioners want to manage chronic hepatitis C and take part in hepatitis C health networks? A national survey].

OBJECTIVES: To assess information that general practitioners had on hepatitis C and on the hepatitis C network in hospitals and private practice. METHODOLOGY: A national telephone survey of 604 general practitioners was conducted between March 18 and 23, 1998. RESULTS: Screening and management of hepatitis C was important for 89% and 97% of general practitioners. Screening was performed in relation to the relative risk (IV drug users 89%, blood transfusion before 1991 88%). General practitioners wanted more information on treatment (54%), patient counselling (42%) and the potential risks of the disease (42%). Of 604 general practitioners, 6% were involved in a hepatitis C network, while 21% were involved in another network (drug users 9%, AIDS 8%). Of the 94% general practitioners who were not part of the network, 33% were willing to join a hepatitis C network. Only 56% were aware of a hepatitis C network (press article 30%, mailing 17% or local meeting 12%). The difficulties for the involvement of general practitioners were: lack of time, topics not adapted to daily practice and geographic constraints (74%), too few patients in their practice (52%), no need (38%), the idea itself of a network and lack of information (28%). CONCLUSION: General practitioners screen patients at risk of hepatitis C. They want to be better informed about treatment, patient counselling, and the potential risks of hepatitis C. They are less involved in hepatitis C networks than in other networks (drug, AIDS). However, one third of general practitioners would like to be involved in a hepatitis C network. These results could be useful for implementing post-graduate courses and general practitioner training.

[Pasteur's neurologic disease].

Based on Pasteur's own documents and studies devoted to him, we reconstruct the clinical presentation of his disease. At the age of 46, Pasteur suffered a left hemiplegia, probably with definitive dequellae related to a cavernoma. Ten years later, he developed signs of disturbed expression then a pseudo-bulbar syndrome. Possible causes are discussed.

Seroepidemiologic screening of Echinococcus multilocularis infection in a European area endemic for alveolar echinococcosis.

In a serologic survey for Echinococcus multilocularis infection, we screened sera from 7,884 subjects from the Doubs Departement in France, an area endemic for alveolar echinococcosis (AE) of the liver. An enzyme-linked immunosorbent assay (ELISA) with a highly species-specific antigen (Em2) and an E. multilocularis crude antigen (Emc) was used for screening. An evaluation of the cost/benefit relationship of this screening, followed by therapeutic management of patients, was made and compared with the actual cost of the follow-up and treatment of the disease in symptomatic cases in this endemic area. Antibody reactions to Em2 and/or Emc made possible the detection of eight asymptomatic clinical cases (seroprevalence averaging 1/1,000), with typical lesions of active AE revealed by abdominal ultrasonography and computed tomography. All were seropositive using the Emc ELISA but two were seronegative using the Em2 ELISA. In five additional seropositive cases, the radiologic investigations revealed small calcified lesions similar to the lesions of abortive AE previously found in Alaska. The cost of this serologic screening program per screened subject and per diagnosed case averaged 50.00 French Francs (FF) (U.S. $8.60) and 60,000.00 FF (U.S. $10,909.00), respectively. The cost of diagnosis, follow-up and treatment of the patients was 5,086.00 FF (U.S. $929.00) per patient per month in the case of diseases diagnosed by the screening program and 7,086.00 FF (U.S. $1,288.00) per patient per month for patients with symptomatic AE. This survey indicates a high prevalence of AE in the target area; it confirms the long latency period of the larval growth in human AE and shows that abortive AE is present in Europe. The use of both the Emc and Em2 ELISAs seems to be better than using the Em2 ELISA alone. The cost of the hospitalization and treatment of the eight screened patients would appear to be relatively high. Even though two of them were asymptomatic, they had very severe forms of the disease. In fact, the total cost was much lower than the actual cost of the disease when diagnosed from clinical symptoms.
