HIV-1 detection by nested PCR and viral culture in fresh or cryopreserved postmortem skin: potential implications for skin handling and allografting
No full textAIMS: To date, the risk relating to the handling or allografting of human immunodeficiency virus type 1 (HIV-1) infected postmortem skin remains hypothetical. While blood screening for HIV antibodies is still the key safety procedure to detect HIV infected cadavers, false negative results are a concern. Conversely, false positive results may hamper the collection of skin allografts. Accordingly, viral culture was used to clarify skin infectivity and the nested polymerase chain reaction (PCR) was used to assess the reliability of skin PCR testing. METHODS: Viral culture and nested PCR performed with gag and pol specific primers were investigated in cadaveric skin and blood from 12 HIV-1 infected patients. Samples were collected repeatedly between one and five days in seven patients. In most cases, analyses were performed on triplicate skin samples: fresh (n = 26); cryopreserved in 5% dimethylsulphoxide (n = 21), or cryopreserved in 30% glycerol (n = 26). RESULTS: HIV was isolated in two of 26 cultures of fresh skin specimens (8%), seven of 47 cryopreserved skin specimens (15%), and eight of 26 blood specimens (31%). The nested PCR detected HIV-1 in all skin samples (n = 73), regardless of the postmortem interval or cryopreservation. In blood, a positive signal was found in eight of 12 patients but two of them had discordant results on successive samples. CONCLUSIONS: These data suggest that nested PCR on postmortem skin samples can detect HIV more reliably than on blood. They also demonstrate the potential viral infectivity of fresh or stored skin postmortem samples in HIV infected patients. They underscore the need for caution during the handling of skin tissue from HIV infected cadavers and confirm the potential risk related to accidental allografting of HIV contaminated skin
Successful treatment with voriconazole of prolonged Paecilomyces lilacinus fungemia in a chronic hemodialyzed patient
No full textPaecilomyces lilacinus is a saprophytic mould which rarely causes infection in humans. We report a case of Paecilomyces lilacinus catheter-related fungemia in a chronic hemodialyzed patient. Blood cultures remained positive for 8 weeks. The infection was cured after eventual acceptance by the patient of oral voriconazole treatment for 6 weeks and removal of the tunneled catheter. The literature on Paecilomyces fungemia in humans is reviewed

Epidemiology and prevention of Clostridium difficile infections in a leukemia unit.
No full textA 29-month prospective study was carried out in a leukemia unit with the aim of investigating the epidemiology of Clostridium difficile infections and limiting their spread. Systematic cultures of stools and assays for cytotoxin were performed on patient admission and at weekly intervals, yielding 1,355 cultures and assays. The study period was divided in period A, before total unit renovation, and period B, afterwards. During period B all patient carriers of Clostridium difficile received vancomycin. A comparison of the two periods showed that the percentage of positive cultures fell from 16.6% to 3.6% and the positive toxin assays from 9.9% to 1.2%. It was concluded that colonization by Clostridium difficile can be prevented in hospital wards with generally high rates of infection by a combination of decontamination of the environment, introduction of preventive measures and treatment of Clostridium difficile carriage with vancomycin
La co-infection par le virus de l'immunodéficience humaine (VIH) et le virus de l'hépatite C (VHC) ou le virus de l'hépatite B (VHB)
No full textCo-infection HIV/HCV or HBV is frequent because of the common ways of transmission of these various viruses. HIV-infected patients are living longer since the introduction of highly active antiretroviral therapy. However, co-infection with the hepatitis C virus (HCV) or hepatitis B virus leads to increased morbidity from liver disease and higher overall mortality. Noxious interactions between these viruses are currently well-known in particular acceleration by the HIV of the natural history of HCV or HBV infection. Recent progress was made in the diagnosis and management of the patients Co-infected by HIV/HCV or HBV Although remarkable, this progress does not occult the need for continuing the preventive measures to reduce the acquisition of new infections and the development of new drugs more effective and better-tolerated to ensure a more important therapeutic success for all the Co-infected patients
Fluconazole Orally Dispersible Tablets for the Treatment of Patients with Oropharyngeal Candidiasis
No full text The efficacy and tolerability of fluconazole orally dispersible tablets (ODT) in the treatment of oropharyngeal candidiasis was evaluated in this multicentre non-comparative study. A total of 89 adults with signs and symptoms of oropharyngeal candidiasis were enrolled; 70 of whom completed therapy with fluconazole ODT 100 mg once daily for 7–14 days. Acquired immunodeficiency syndrome (AIDS)/ AIDS-related complex was an underlying illness in 69% of patients (61). An antimicrobial and corticosteroid therapy was given in 52% (46) and 20% (18) of patients, respectively. Of the 60 patients who had baseline signs and symptoms of infection and a culture positive for Candida albicans, 90% (54) were cured or had improved at the end of therapy, and the fungal pathogen was eradicated in 19/57 (33%) patients. At the 4-week post-treatment follow-up, signs and symptoms of oropharyngeal candidiasis were absent in 73% (27/37) patients. The adverse events and laboratory abnormalities recorded during the study period were attributable to underlying illnesses rather than to fluconazole therapy. These results indicate that this novel dosage form of fluconazole is effective and well tolerated in the treatment of oropharyngeal candidiasis. </jats:p
Vaccinations for adult solid organ transplant recipient: current recommendations.
No full textThe need for immunization in solid organ transplant recipient can arise from three factors: immune deficit owing to underlying disease, rejection of the organ graft, and immunosuppressive therapy given after transplantation. As a general rule, primary immunizations should be given as early as possible before transplantation because the immune response to vaccines is decreased in patients with end-stage organ disease. There are three categories of vaccines: Live vaccines--oral polio, vaccinia, bacillus Calmette-Guerin, live oral typhoïd, and intranasal influenza vaccines--are contraindicated in solid organ transplant recipients. The use of varicella vaccine remains controversial. The use of rubella vaccine is recommended in young women of childbearing age. Of the killed vaccines or genetically engineered vaccines, the following are recommended: pneumococcal vaccine, influenza vaccine, hepatitis A vaccine, hepatitis B vaccine, diphtheria, and tetanus vaccine. Vaccination of household contacts and health care workers in transplant centers is recommended. However, live vaccine (with the exception of varicella vaccine) should be avoided in these contacts
