The authors demonstrate in vitro antiviral activity of a methanolic extract of Combretum micranthum leaves against HSV-1 and HSV-2. This activity is present only in the extract dissolved 7 days before the assay, but not in the freshly prepared extract, thus indicating the presence of inactive precursors which undergo spontaneous transformations into active(More)
BACKGROUND In recent years, Highly-Active Anti-Retroviral Therapies (HAARTs) have modified the Human Immunodeficiency Virus (HIV) life-cycle and the disease is now considered chronic. Consequently, a longitudinal and complex follow-up is now required for HIV positive patients during their lifetime. Moreover, patients often encounter various complications(More)
The serum concentrations and safety of single daily dosing of amikacin were studied in 16 episodes of fever and granulocytopenia in children undergoing bone marrow transplantation. Amikacin (20 mg/kg) was administered as a 20 min iv infusion once daily for 7 to 19 days; all patients received concomitant therapy with ceftazidime. Peak amikacin concentrations(More)
The population pharmacokinetics of teicoplanin in plasma and tonsillar tissue in children was determined following intramuscular administration. Thirty seven patients in all received either a single 5 mg/kg dose; 2 doses of 5 mg/kg, 12 h apart; 3 doses of 5 mg/kg, 12 h apart; or, a single 10 mg/kg dose. Limited data, comprising a maximum of 2 blood samples(More)
METHOD Analysis of virological, immunological, and clinical data over 24 weeks of treatment of drug-experienced patients administered didanosine (ddI) and tenofovir (TDF) plus either PI or NNRTI (17 patients) compared to 14 patients on ddI plus lamivudine and to 19 patients on ddI plus stavudine. RESULTS Patients treated with TDF and ddI do not have a(More)
The pharmacokinetics of teicoplanin have been studied in 13 pediatric male patients from 2 to 12 years of age. Patients were given a single 3-mg/kg intravenous dose of teicoplanin for prophylaxis. Blood and urine samples were collected for 8 days after administration, and teicoplanin levels were determined by microbiological assay. Pharmacokinetic(More)
INTRODUCTION The persistence of immune activation and inflammation in HIV patients with HIV-RNA (VL) undetectable causes many co-morbidities [1-3]. The aim of this study is to correlate monocytes (m) and NK cell activation levels, soluble markers and oxidative stress with clinical, biochemical and metabolic data in HIV-1 infected patients with VL≤50 copies(More)
BACKGROUND Visceral Leishmaniasis (VL) is endemic in 88 countries, in areas of relatively low incidence with a relevant proportion of immune suppressed patients clinical presentation, diagnosis and management may present difficulties and pitfalls. METHODS Demographic data, clinical, laboratory features and therapeutic findings were recorded in patients(More)
Although rather uncommon and multifactorial in etiology, liver cirrhosis is a severe and often rapidly fatal disease in pediatrics. In our institution, during the last 15 years, 22 children with liver cirrhosis have been followed. The underlying predisposing condition was HBV infection (8 cases), CMV perinatal infection (2 cases), Wilson's disease (4(More)
