Coeliac disease in chronic hepatitis C: a French multicentre prospective study.

BACKGROUND: A prevalence of 1.2% of coeliac disease (CD) in patients with chronic hepatitis C was recently reported, suggesting a possible epidemiological link between these two diseases. However, other studies have not found this relationship. AIM: To conduct a French multicentre prospective study to assess the prevalence of CD in hepatitis C virus (HCV)-infected patients. METHODS: Between June 2003 and November 2005, 624 consecutive HCV-positive out-patients were tested for antiendomysial IgA antibodies (AEA), antigliadin IgA and IgG antibodies (AGA). Patients with positive AEA or IgA AGA and positive IgG AGA in a context of a high suspicion of CD were asked to undergo gastroscopy with duodenal biopsies. RESULTS: Isolated IgA AEA, IgA AGA and IgG AGA were 0.16%, 5.7% and 4.4%, respectively. Gastroscopy was required for 39 patients, 31 were performed (eight refusals), but only 25 duodenal biopsies were performed as six patients had cirrhosis. CD was never detected. CONCLUSIONS: The prevalence of CD in HCV-positive patients was 0% (95% confidence interval: 0-0.59%), but there is a low prevalence of CD in the whole French population.

Epidemiology of chronic hepatitis B infection in France: risk factors for significant fibrosis--results of a nationwide survey.

BACKGROUND: Epidemiological data concerning hepatitis B are scarce in France. AIM: To describe epidemiological, clinical, virological and histological features of HBsAg-positive patients followed at non-academic hospitals in France. METHODS: Clinical, biological, virological and histological data of all HBsAg-positive consecutive patients observed from April 1, 2001 to May 31, 2002 in participating centres were recorded prospectively. Multivariate analyses of factors associated with significant fibrosis and cirrhosis were performed. RESULTS: Nearly 1166 HBsAg-positive patients were seen in the 58 centres: 671 males and 495 females from metropolitan France (32%) and from outside metropolitan France (68%); mean age 41 +/- 15 years. Twenty-nine percent of patients were probable HBsAg inactive carriers, while 50% had chronic hepatitis; 43% of these were HBeAg-positive and 57% HBeAg-negative. Liver biopsy had been performed in 558 (51%) patients; 205 (17.6%) patients had cirrhosis. By multivariate analysis, factors associated with significant fibrosis were: age >40 years (P < 0.05), HBeAg-negative status (P < 0.02) and histological activity (P < 0.0001). Factors associated with cirrhosis: age (P < 0.0001), platelet count <150 000/mm(3) (P < 0.0001) and viral co-infection (P < 0.03). CONCLUSION: HBV infection represents a significant workload for hepatogastroenterologists at non-academic hospitals in France.

Retrospective investigation of patients exposed to possible transmission of hepatitis C virus by a capillary blood glucose meter.

A 75-year-old female with no known risk factors for hepatitis C virus (HCV) infection was hospitalized and a diagnosis of HCV seroconversion was established (HCV immunoblot and a positive quantitative viral load). An epidemiological investigation revealed that, during a previous hospitalization resulting in a diagnosis of diabetes, she had shared a Glucotrend capillary blood glucose meter (CBGM; Roche Diagnostics, France) with a known HCV-positive diabetic patient. Poor hygiene practices were observed when using this device. Since the Glucotrend CBGM had been purchased, the suspected source patient had been hospitalized eight times and another 19 diabetic patients with known anti-HCV antibodies also regularly attended the same hospital. Consequently, 35 diabetic patients who had been hospitalized at the same time as the suspected source patient and 1305 patients who had used the Glucotrend CBGM were invited to undergo serum anti-hepatitis B virus, anti-HCV and anti-human immunodeficiency virus testing. Among the 35 diabetic patients, none of the 24 subjects tested were positive. Among the 1305 other patients, 995 were tested and 19 (2%) were anti-HCV positive. Although this prevalence is higher than that reported in the general French population, this excess risk cannot be attributed to use of the CBGM. Furthermore, molecular analysis showed that the two HCV strains isolated did not belong to the same phylogenetic cluster. However, as a result of this incident, measures were taken to minimize the transmission of bloodborne viruses in the hospital concerned. Other French hospitals were informed by a national alert message from the French Agency for the Safety of Health Products.

Treatment of chronic hepatitis C with amantadine hydrochloride in patients who had not responded to previous treatment with interferon-alpha and/or ribavirin.

Seven women and 3 men infected with hepatitis C virus, all of whom had failed to respond to therapy with either IFN-alpha or IFN and ribavirin, were treated with 200 mg/day of amantadine hydrochloride for 12 months. We found a significant decrease of serum ALT activity without any decrease in virus load. These results suggest that amantadine hydrochloride should not be used as monotherapy for patients who do not respond to treatment with IFN-alpha and/or ribavirin.

[Hepatitis C epidemiology at a general hospital center. Management and natural history as a function of the manner of identification]. / Epidémiologie de l'hépatite C dans un centre hospitalier général. Prise en charge et histoire naturelle en fonction du mode de découverte.

OBJECTIVES: To study the epidemiological characteristics of patients with chronic hepatitis C virus followed in a primary referral hospital and the clinical influence of "systematic screening" defined as the screening of patients without symptoms and with known risk factors of hepatitis C (past transfusion, past or present intravenous drug use, haemodialysis) on the natural history and treatment of chronic hepatitis C virus. METHODS: The files of 311 consecutive patients who screened positive for anti-hepatitis C virus and were seen at the primary referral hospital, Creil, from January 1992 to February 1996, were analyzed. RESULTS: Patients who underwent "systematic screening" were younger with a shorter duration of infection. They were more often intravenous drug addicts and had lower alanine aminotransferase activity and Knodell scores than patients who underwent screening during "a diagnostic procedure", because of symptoms and/or abnormal liver biochemistry. Increased age at contamination and alcohol consumption of more than 40 g per day was associated with an increased risk of cirrhosis while patients who underwent "systematic screening" had a lower risk of cirrhosis and higher survival rate. Interferon therapy was attempted less often in anti-hepatitis C virus positive patients from "systematic screening" programs. CONCLUSIONS: Anti-hepatitis C virus positive patients from "systematic screening" programs had a benign disease and were rarely treated with interferon compared to anti-hepatitis C virus positive patients diagnosed during a "diagnostic procedure".

[Hepatitis B: epidemiology, natural history, biology, treatment monitoring]. / Hépatite B: épidémiologie, histoire naturelle, biologie, surveillance du traitement.

Hepatitis B virus (HBV) infection is a worldwide public health problem. In France, 150,000 individuals are infected with the HBV. Although many are asymptomatic carriers, about 30% have chronic hepatitis, a condition associated with a risk of cirrhosis and hepatocellular carcinoma. Antiviral treatments, most notably interferon alpha, probably modify the natural history of hepatitis B, decreasing the risk of hepatocellular carcinoma and increasing survival. Nucleoside analogs, particularly lamivudine, have also demonstrated potent antiviral activity, which should however be weighed against the increasing risk over time of mutation development in the YMDD region of the DNA polymerase reverse transcriptase. Antiviral therapy monitoring should include clinical safety evaluations and periodic laboratory tests including blood cell counts, transaminase activities, and serum DNA levels. The improving results provided by antiviral drugs should not deflect attention away from the importance of large-scale hepatitis B immunization of neonates, which has been shown to decrease the incidence of hepatocellular carcinoma in areas with high levels of hepatitis B endemicity.

Slow progression rate of fibrosis in hepatitis C virus patients with persistently normal alanine transaminase activity.

In hepatitis C virus (HCV) patients with persistently normal alanine transaminase (ALT), the progression rate of fibrosis is unknown. The aims of this study were: 1) to compare HCV patients with normal ALT (group I) with HCV patients with elevated ALT (group II) matched on independent factors associated with fibrosis; and 2) to assess the progression rate of fibrosis. One hundred two HCV patients were included in each group. Histological lesions were staged using the METAVIR score. We defined fibrosis progression per year as the ratio of the fibrosis stage in METAVIR units to the duration of infection. In group I, ALT values were normal, and lower than in group II (25 vs. 127 IU/L; P < .0001). HCV RNA was present less frequently in group I (66% vs. 97%; P < .0001). There were no significant differences for viremia and genotypes. Histological activities were lower in group I (0.6 vs. 1.38; P < .0001). The stage of fibrosis was lower in group I (0.95 vs. 1.8; P < .001). The median progression rate of fibrosis was lower in group I (0.05 vs. 0.13; P < .001). In group I, after exclusion of negative HCV-RNA patients, the median progression rate of positives remained lower (0.05 vs. 0.13; P < .001). In group I, all cirrhotic patients (n = 3) were heavy drinkers. HCV patients with normal ALT showed weaker histological activity and lower fibrosis scores, and the progression rate of fibrosis was twice as slow as in HCV patients with elevated ALT. In these patients, severe fibrosis was associated with high alcohol consumption.

[Coexistence of myeloma and chronic myeloid leukemia]. / Coexistence d'un myélome et d'une leucémie myéloïde chronique.

The case of an eighty-one-year-old woman who had myeloma followed 18 months later by chronic myeloid leukemia with Philadelphia chromosome unrelated to therapeutic interferences is reported. This case is compared to other reports of lymphoid hemopathies associated with myeloid hemopathies found in the medical literature. The different etiopathogenic hypotheses are discussed, particularly in the light of recent studies of chromosomes. Such caryotypic studies in malignant hemopathies may improve our knowledge of the connexions between apparently dissimilar diseases and prove helpful for the understanding of cell differentiation from pathological data.

[A systematic search for Ureaplasma urealyticum in vaginal swabs. The results (author's transl)]. / Recherche systématique d'Ureaplasma urealyticum au cours des prélèvements vaginaux. Résultats.

6.6 per cent 1.069 vaginal swabs showed Ureaplasma urealyticum in our patients. Ureaplasma does not seem to alter the cytology or the physiological flora of the vagina. On the other Hand trichomonas vaginalis was often found in association with it. There is no racial predisposition to infection of the vagina with Ureaplasma. Pregnancy, however, does seem to favour the growth of this mycoplasma. But this does not seem to have any adverse effect on the progress of the pregnancy.

[2 cases of Plasmodium falciparum malaria. Probable responsibility of Anopheles transported by air]. / A propos de deux cas de paludisme à Plasmodium falciparum. Responsabilité probable d'anophèles importés par voie aérienne.

Report of two cases of Plasmodium falciparum malaria which seem to be originary from the Pariser area: the first one in a luggage carrier working in an airport; the second one in a subject living in the neighbourhood of this airport. These cases perhaps question the hygiene measures taken on the arrival of planes coming from impalutaded regions.
