Earlier onset and poor prognosis of lung cancer in imprisoned patients.

INTRODUCTION: Prison inmates are known to be more exposed to various lung cancer risk factors, and some studies have shown that lung cancer is the most common cancer in prisoners. However, no study has particularly focused on lung cancer features in this population. METHOD: Charts of patients with lung cancer hospitalized in one of the French secured hospital units between 1997 and 2012 were reviewed. Data from this cohort were then compared to those of two large observational studies conducted in 2000 and 2010 (KBP studies). RESULTS: Thirty-two cases were included. All were men. The mean age was 52.2 ± 11.5 years, which was significantly lower than in the KBP-2000 (64.4 years) and KBP-2010 (65.5 years; both p < 0.0001) studies. The percentage of current smokers was much higher in prisoners (87.1 vs. 52.2 and 49.2%, respectively; both p < 0.001). Ninety percent of prisoners presented with at least one comorbidity. Lung cancer clinical presentation did not differ between prisoners and the reference populations. The median overall survival was 5.8 months (range 0-15.1) for all stages and 4.7 months (range 2.8-6.6) for stage IIIB/IV. CONCLUSION: Although our study suffers from limitations, prisoners seem to develop lung cancer at a younger age and their prognosis is poor.

[Alcohol, steatohepatitis, insulin resistance and hepatitis C]. / Alcool, stéatohépatite métabolique, insulinorésistance et hépatite C.

Patients with chronic hepatitis C have frequently other morbidities, either because they are frequent in the general population (metabolic syndrome) and/or because the route of contamination (chronic alcohol consumption succeeding to drug abuse). These co-morbidities have a harmfull impact on fibrosis progression during the natural history of HCV infection and reduce the efficacy of antiviral treatments. Thus, it is crucial to diagnose early and treat these different diseases which may be combined. They are the metabolic syndrome and/or chronic alcohol consumption resulting in insuline resistance, infection by the human immune deficiency virus or by the hepatitis B virus as well as chronic tobacco use or excessive consumption of cannabis. An optimal is based on a multidisciplinary approach to reduce fibrosis progression and improve the efficiency of antiviral therapies. However, the hepatologist has to come back to a global care, which is mandatory at the individual level as well as for the public health.

A French prospective observational study of the treatment of chronic hepatitis C in drug abusers.

The objective of this prospective, multicenter, observational study was to evaluate healthcare for hepatitis C virus (HCV)-infected drug abusers in France and to determine predictors of successful therapeutic intervention. A total of 170 drug users were recruited from 40 French centers. Three centers recruited 66 participants (38.8%), and one to eight patients each were enrolled from 37 other centers (n=104). A sustained viral response (SVR) was seen in 65 (38.2%) patients. SVR rates were significantly higher in compliant than in non-compliant patients (43.5% versus 23.9%; P=0.019), in patients from high- rather than low-recruiting centers (54.5% versus 27.9%; P<0.001) and in patients receiving Buprenorphine rather than methadone (48.1% versus 21.8%; P=0.001). In patients, who completed both the treatment and follow-up (n=94), SVR rate was 57.4%. Buprenorphine substitution therapy and genotypes 2 or 3 HCV infection were associated with significantly higher rates of SVR (P<0.01, for both comparisons). In conclusion, successful care of hepatitis requires an active treatment policy of every center toward drug addicts. Additional studies are needed to explore the difference in SVR with methadone versus Buprenorphine therapy.

The carboxy-terminal cross-linked telopeptide of type I collagen (ICTP) is a potential serum marker of ongoing liver fibrosis.

We report for the first time the measurement of the serum concentration of the carboxy-terminal cross-linked telopeptide of type I collagen in patients with various liver diseases. This breakdown product of type I collagen, which is the major collagen type found in fibrotic liver, was measured by a radioimmunoassay in the serum of 149 patients with various liver diseases and in 67 controls. Its concentration is significantly elevated (P < 0.05) above reference intervals in sera from patients with liver diseases, except in patients with chronic active hepatitis of unknown origin and in patients with acute hepatitis A. In the 143 patients with liver fibrosis, the serum level of the carboxy-terminal telopeptide of type I collagen is correlated with the extent of fibrosis, as assessed by a histological scoring system (r = 0.3899, P < 0.0001), but not with inflammation and necrosis.

[Influence of HIV infection on hepatitis B virus infection in homosexual patients]. / Influence de l'infection à VIH sur l'infection par le virus de l'hépatite B chez les patients homosexuels.

Clinical expression and outcome of hepatis B virus infections associated with human immunodeficiency virus infection (without AIDS) were studied in 17 homosexuals during 23 months. In an attempt to distinguish the respective impacts of homosexuality from that of human immuno-deficiency virus, patient were compared with a population of homosexual males infected by hepatitis B virus alone. The ratio of biochemical evidence of liver cell necrosis (ALAT)/viral replication (DNAp) was significatively decreased (p less than 0.01), despite evidence of severe histological damage in some cases. Two-thirds of patients with HBV replication tolerated HBV infection at the end of follow-up. This tolerance was significatively more common than in homosexuals infected by HBV alone (p less than 0.01), and did not appear to be related to decreased T4 cell count but seemed to correlate with the existence of the AIDS related complex.

[Vidarabine treatment of chronic active hepatitis associated with hepatitis B virus multiplication. A randomized multicenter study]. / Traitement par la vidarabine de l'hépatite chronique active associée à la multiplication du virus de l'hépatite B. Etude multicentrique randomisée.

A randomized controlled study of one course of vidarabin was carried out in 30 patients with HBs Ag, HBe Ag, DNAp, positive chronic active hepatitis: 15 patients were treated with vidarabin given intravenously (15 mg/kg/day for 7 days then 7.5 mg/kg/day for 14 days); the other 15 patients received a placebo for 21 days. During treatment, DNA polymerase activity fell dramatically in 13 treated patients and in no controls (p less than 0.001). Six months after inclusion, ALT normalization was observed in 40 p. 100 of the treated patients and 6 p. 100 of the controls (p less than 0.05), a decrease in inflammatory activity on liver biopsies was observed in 70 p. 100 of the treated patients and 20 p. 100 of the controls (p less than 0.05), a permanent lost of DNA polymerase and of HBe Ag occurred in 33 p. 100 and 13 p. 100 of the treated patients and 20 p. 100 and 7 p. 100 of the controls, respectively. In addition, a second course of vidarabin was administered to the 12 patients who were still HBe Ag positive 6 months after the first course. During the next 6 months, 8 patients lost DNA polymerase and 4 lost HBe Ag. Altogether, the final score of durable inhibition of HBV replication was 11/15 (73 p. 100) within one year. The above results demonstrate that one course of vidarabin can significantly improve ALT and liver inflammatory activity but the effect upon HBV replication is only transient. A second course does however increase efficacy on HBV replication without additional side effects.

[Effects of a postpituitary extract and lysine vasopressin on portal and systemic hemodynamics in the cirrhotic patient]. / Effets d'un extrait de post-hypophyse et de la lysine vasopressine sur l'hémodynamique portale et systémique chez le cirrhotique.

The purpose of this work was to study the hemodynamic effects of a pituitary extract (Post-Hypophyse, Choay, EPH) and of lysine vasopressin (Diapid, Sandoz, VP). Cardiac, pulmonary and liver hemodynamics were measured in 50 cirrhotic patients before and during intravenous infusion (0.45 IU/kg/h) of EPH (24 patients) or VP (26 patients). EPH and VP did not have identical consequences in cardiac output and systemic resistances. EPH significantly increased cardiac output and significantly decreased systemic resistances while VP significantly and increased systemic resistances. Both vasoactive drugs similarly decreased myocardial performances. EPH and VP had a moderate influence on WHV/IVC pressure gradient. This was variable from one patient to another. The decrease of WHV/IVC pressure gradient observed during EPH infusion was mainly related to an increase of IVC pressure. Since the effects of both drugs on WHV/IVC pressure gradient are slight and unpredictable and they exert an important effect on cardiopulmonary hemodynamics, caution should be taken in administering EPH or VP to cirrhotic patients. The clinical use of EPH or VP should be undertaken only when cardiac and liver hemodynamics monitoring are available.

[Patients with alcoholic liver disease hospitalized in gastroenterology. A national multicenter study]. / Maladies alcooliques du foie hospitalisées en Hépato-Gastroentérologie. Enquête multicentrique nationale.

OBJECTIVES: To describe the characteristics of in-patients with alcoholic liver disease in Hepatogastroenterology and to evaluate whether geographic location was a risk factor for cirrhosis. METHODS: A French, national, multicenter, prospective investigation was performed in the last quarter of 1997. To be included in the study, patients had to have drunk at least 50 g of alcohol per day for the past year or to have cirrhosis. RESULTS: Seventeen centers included 802 patients, 20% had histologically proven cirrhosis or probable cirrhosis. Thirty-five percent had undergone liver biopsy. Twenty five percent of these patients had cirrhosis without acute alcoholic hepatitis and 37% had cirrhosis with acute alcoholic hepatitis. After dividing France along a Bordeaux-Strasbourg axis, there was more histologically proven or probable cirrhosis in the North (46%) than in the South (36%) (P<0.005) while daily alcohol intake was greater the South (150 +/- 6 g) than in the North (129 +/- 4 g) (P<0.0001). When the six variables (age, sex, daily consumption of alcohol over the past 5 years, presence of hepatitis B surface antigen and antibodies to hepatitis C virus, total duration of alcohol abuse) were considered together in stepwise logistic regression analysis, geographic location changed the prediction of cirrhosis. The odds ratio for cirrhosis in patients living to the North of the Bordeaux-Strasbourg axis was 1.9 (95% confidence interval range 1.1-3.2) (P<0.02), suggesting the role of nutritional factors.

[Epidemiology of acute hepatitis among outpatients in the urban community of Lyon, 1983]. / Epidémiologie des hépatites aiguës survenues chez des malades ambulatoires dans la communauté urbaine de Lyon, en 1983.

We conducted in 1983 an hepatitis surveillance programme in collaboration with 93% of the medical analysis laboratories in Lyons' urban area (1,100,000 inhabitants) and diagnosed 1,002 cases of acute hepatitis (incidence : 90.5 cases/10(5) inhabitants; HAV : 50.4 cases/10(5) inhabitants; HBV : 12 cases/10(5) inhabitants; non A non B : 24 cases/10(5) inhabitants; drugs : 4.2 cases/10(5) inhabitants). HBs Ag was undetectable in 12% of acute hepatitis B. Hepatitis A accounted for 91% of children's cases and 48% of cases among adults between 20 and 40 years old. Epidemics were observed among children after summer holidays related to the return of migrants from trips to their native country. For acute hepatitis B and non A non B, classical epidemiological data were observed, but the prevalence of drug addicts and homosexuals was low.

[Cost of acute hepatitis A in adults in France]. / Coût en France des hépatites A aiguës de l'adulte.

OBJECTIVES: Seroprophylaxy against hepatitis A has been limited to subjects visiting endemic areas or in contact with acutely infected patients due to the short half-life and high cost of the non-specific immunoglobulins. Inactivated vaccines might offer a better solution, but the real cost factors remain unknown. We undertook this study to determine the cost of acute hepatitis A. METHODS: Serum samples from all the non-hospital medical laboratories in the Lyon (France) area were prospectively screened to identify 100 consecutive patients with acute hepatitis (positive for hepatitis A IgM antibodies). A questionnaire was addressed to these 100 subjects 1 year later requesting information on health care expenditures and work loss related to their episode of acute hepatitis A. Imprecise answers were completed by telephone interview. RESULTS: Answers were obtained from 92 subjects. Confirmation was obtained that the 8 other subjects had not died from their episode of acute hepatitis. Only two patients were hospitalized (for 2 and 4 days). Total mean cost (including medical expenditures and work loss was 11,789 French francs (range 1,524-62,117). Medical consultations and prescriptions comprised 20.0% of the total cost. The real mean cost of work loss (8,423 F) was greater than the cost calculated by the national health service (6,500 F). CONCLUSIONS: This evaluation of the real cost of hepatitis A in non-hospitalized patients should contribute to the definition of an adapted policy for the prevention of hepatitis A.

[Epidermolysis bullosa acquisita and hepatitis C]. / Epidermolyse bulleuse acquise et hépatite virale C.

INTRODUCTION: Epidermolysis bullosa acquisita is a bullous dermatosis. Its etiology remains unknown and the efficacy of its treatment is low. OBSERVATION: We report the first association between epidermolysis bullosa acquisita, chronic hepatitis C and cryoglobulinemia, healing with interferon alpha and ribavirine. DISCUSSION: We suggest a role for hepatitis C virus in the pathogenesis of epidermolysis bullosa acquisita. We suppose a synthesis of autoimmune antibodies in a dysimmune environment. Interferon alpha and ribavirine might be a new therapeutic avenue but further studies are necessary to confirm it.
