[Treatment of hepatitis C virus infection in the Poitou- Charentes region]. / Prise en charge de l'infection par le virus de l'hépatite C dans la région Poitou-Charentes.

OBJECTIVES: The prognosis of hepatitis C virus infection could be improved by early treatment. However, this is only possible if most patients with hepatitis C consult a specialized institution. The aim of this study was to evaluate the modalities of care of hepatitis C virus infection in one French district. METHODS: Between November and December 1997, 89 biological laboratories from the "Poitou-Charentes" district were asked to provide results of hepatitis C virus serology tests performed during this period. A questionnaire concerning epidemiological and follow-up data was sent to the medical practitioner who prescribed the test, for all positive tests. RESULTS: Seventy eight out of 89 (88%) laboratoires agreed to participate in the study. During the study period, 6,168 subjects were tested and 196 (3.2%) were positive. This test was a diagnostic test in 69 cases (53%) and a confirmation test in 61 cases (47%). The epidemiological questionnaire was filled out in 130 cases. The main putative factors of viral contamination were: intravenous or nasal drug addiction in 69 cases (53%), blood transfusion in 39 cases (30%), and a nosocomial risk factor in 16 cases (12%). Treatment and care of virus infection was evaluated in 113 cases from the follow-up questionnaire: a liver biopsy was performed in 30 cases (27%) and interferon therapy was administered in 13 cases (12%). Liver biopsy was not performed in 83 cases (73%) due to normal transaminase levels or a contraindication to interferon therapy. The main causes of an absence of care or follow-up were: fear of complications of liver biopsy and/or side effects to interferon therapy (19%), chronic alcoholism (18%) and active drug addiction (8%). CONCLUSION: The main causes of failure to administer adequate care in hepatitis C patients were chronic alcoholism, drug addiction and fear of liver biopsy or side effects of interferon therapy. These data should be taken into account for future screening or information compaigns for the general population.

["Primum non nocere". Prospective study of 115 cases of iatrogenic diseases collected over one year in 106 patients]. / Primum non nocere. Etude prospective de 115 observations de pathologies iatrogènes recueillies en 1 an chez 106 malades.

One hundred and fifteen cases of iatrogenic disorders were observed in 106 patients during a one-year prospective study. Each case was included after informed agreement of two investigators. Each case was classified into 4 groups, according to duration time between iatrogenic disorder and hospitalization, and into 3 sections according to responsibility of causative agent. A control group of 200 patients matched for age and sex was studied. Patients represented 8% of the hospitalisations. Mean age (69.2 years) was higher than other patients hospitalized during the same period (61.6 years). Principal causative agents were diuretics (30), physchotrops (13) and technic examinations (12). Main pathologies were electrolytes disorders (28), orthostatic hypotension (19), confusion and/or alteration of mental functions (13), and cutaneous or allergic disorders (12). Mean induced hospitalization duration time was of 8 days. Mean estimate cost was 18,808 francs per patient. Associated factors were elderly, and an elevated number of drugs. A negligency could participate to iatrogenic disorders in 50% of cases. Half part of iatrogenic disorders could be avoided by using simple precautions: respect of contra-indications, restriction on self-therapy and of number of associated drugs.

Hepatic fibrin-ring granulomas in giant cell arteritis.

Hepatic fibrin-ring granulomas were found in a 70-year-old man with prolonged fever and inflammatory syndrome. Diagnosis of giant cell arteritis was confirmed by temporal artery biopsy. Other diseases usually associated with fibrin-ring granulomas in liver, such as Q fever, cytomegalovirus hepatitis, infectious mononucleosis, Hodgkin's disease, non-Hodgkin's lymphoma, allopurinol treatment, and visceral leishmaniasis, were ruled out. This report suggests that giant cell arteritis should be considered as an additional cause of hepatic fibrin-ring granulomas.

[Primum non nocere, a forgotten adage at times. Apropos of 106 cases of iatrogenic pathologies collected in a year]. / Primum non nocere, un adage parfois oublié. A propos de 106 observations de pathologies iatrogènes recueillies en un an.

Results of a prospective trial showed that 7.9% of patients in an internal medicine department were affected by a drug-induced pathology (DIP). Reasons for this include non respect of contra-indications or to non supervision of treatment such as anti-hypertensive drugs. DIP affected more often elderly patients, and reflected superconsummation of medication.
