[Medical treatment in peripheral arterial disease: a professional practice study in 262 patients].

PURPOSE: Antiplatelet agents (APA), statins and angiotensin converting enzyme inhibitors (ACEI) are effective to reduce the risk of cardio-vascular events in patients with peripheral arterial disease (PAD). Few data are available on the actual prescription of these drugs in outpatients and on the effect of hospital care on the level of prescription. METHODS: Retrospective study of patients hospitalized with a confirmed diagnosis of PAD over a one-year period. Comparison of medical treatments on admission and on discharge. RESULTS: 262 patients were included. Mean age was 73 +/- 11 years, and 29% of the patients were women. APA were present in 64% on admission and in 83% when discharged (P < 0.0001). A statin was present in 29% on admission and in 38% when discharged (P = 0.001). ACEI were present in 27% on admission and in 32% when discharged (P= 0.02). A vasodilator was present in 47% on admission and 52% when discharged (P = 0.1). 35% of the patients had isolated PAD. Compared to the patients with associated clinical coronary or cerebro-vascular disease, they were less frequently discharged on statins (respectively 26 and 45%, p = 0.003) and on ACEI (respectively 23 et 38%, P = 0.016) whereas APA were equally prescribed (respectively 82 and 84%, P= 0.7). CONCLUSION: APA were prescribed to a majority of outpatients and the level of prescription was further improved when patients were discharged from the hospital. Statins and ACEI were insufficiently prescribed. On the other hand, vasodilator therapy remained still largely prescribed, despite the lack of any strong effect on morbidity and survival.

Optimized PCR using patient blood samples for diagnosis and follow-up of visceral Leishmaniasis, with special reference to AIDS patients.

We developed a highly sensitive PCR method that enables the diagnosis and posttherapeutic follow-up of visceral leishmaniasis with patient blood. The PCR assay was thoroughly optimized by successive procedural refinements to increase its sensitivity and specificity. It was compared to in vitro cultivation as well as to direct examination of bone marrow and to serology. Two hundred thirty-seven patients presenting with clinical signs compatible with visceral leishmaniasis were included in the study. Thirty-six were diagnosed as having Mediterranean visceral leishmaniasis (MVL). Twenty-three of them, including 19 AIDS patients, were monitored during and after treatment over a period from 2 weeks to 3 years. Our PCR assay proved more sensitive than in vitro cultivation, direct examination, and serology for all patients. It is simple and can be adapted to routine hospital diagnostic procedures. For the primary diagnosis of MVL, the sensitivity of PCR versus that of cultivation was 97 versus 55% with peripheral blood and 100 versus 81% with bone marrow samples. Regarding posttherapeutic follow-up, overall, 48% of positive samples were detected by PCR only. Seven patients presented with a clinical relapse during the study; six relapses were detected at first by PCR only, sometimes a few weeks before the reappearance of signs or symptoms. We conclude that an optimized and well-mastered PCR assay with a peripheral blood sample is sufficient to provide a secure diagnosis for all immunocompromised patients and most immunocompetent patients. We also suggest systematic posttherapeutic monitoring by PCR with peripheral blood for immunocompromised patients.

Treatment of Waldenstrom's macroglobulinemia with very low doses of alpha interferon.

Waldenström's macroglobulinemia (WM) is a differentiated B-cell malignancy which is usually less responsive to standard chemotherapy because of low-proliferating cells. Interferon alpha has been shown to possess a therapeutic action in numerous B-cell malignancies including the early stage of chronic lymphocytic leukemia, multiple myeloma, follicular lymphoma and hairy cell leukemia. Fourteen patients with progressive WM were included in a pilot study using very low dose of interferon alpha-2a (1 Million Units 3 times a week). The mean duration of treatment was 10.3 months (range 2-44). Six of 14 (42%) patients presented an increase in the hemoglobin level (> or = 0.9 g/dL) and 4/14 (28%) had a substantial decrease of the monoclonal component (> or = 20% of reduction). Only two patients presented both types of response, while the others with an increase in the hemoglobin level had a slight decrease in the monoclonal component (MC) (1 patient), a stable MC (1 patient) or a slight increase of MC (1 patient). One additional patient had a 15% decrease of the MC with a stable hemoglobin level. Response was observed within 3 months with a median duration of 6 months. Treatment was stopped for 3 patients because of flu-like symptoms (2 patients), or thrombocytopenia (1 patient). Follow up was possible in 12 patients lasting up to a maximum of 30 months after discontinuing treatment. Seven patients died, including 4 with progressive disease, two of infection and one of cardiac failure. In the view of these results, very low dose of interferon alpha may constitute a new approach for treatment of some cases of WM.

[Acute myocarditis in non-typhoid Salmonella infection].

The authors report a case of myocarditis secondary to a Salmonella Virchow infection in a 20 year old non-immunodeficient man without a previous medical history. The outcome was favourable after treatment with fluoroquinolone. The features of this rare complication of non-typhic salmonella infection are discussed with respect to this and four other recently published cases.
