ABSTRACT

Opportunistic infections continue to be a cause of morbidity and mortality in HIV-infected patients. They often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an opportunistic infection. The present article is an executive summary of the document that updates the previous recommendations on the prevention and treatment of opportunistic infections in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome. This document is intended for all professionals who work in clinical practice in the field of HIV infection.

ABSTRACT

Despite the huge advance that antiretroviral therapy represents for the prognosis of infection by the human immunodeficiency virus (HIV), opportunistic infections (OIs) continue to be a cause of morbidity and mortality in HIV-infected patients. OIs often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an OI. The present article updates our previous guidelines on the prevention and treatment of various OIs in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome.

ABSTRACT

OBJECTIVES: In vitro studies have shown good activity of linezolid against Mycobacterium tuberculosis, including multidrug-resistant strains. However, clinical experience with linezolid in tuberculosis is scarce. METHODS: We report our clinical experience with five consecutive patients with multidrug-resistant tuberculosis infection treated with combination regimens that included linezolid. RESULTS: Two patients had multidrug-resistant Mycobacterium bovis infection, with resistance to 12 antituberculous agents (one of them with HIV co-infection and <50 CD4 cells/mm(3)). The other three patients were infected by multidrug-resistant M. tuberculosis strains, with resistance to all first-line drugs and other second-line drugs. All patients received linezolid in combination with thiacetazone, clofazimine or amoxicillin/clavulanate. Susceptibility tests showed linezolid MIC values < or =0.5 mg/L against all tuberculosis strains tested (standard proportion method, Middlebrook agar 7H10). In all cases, tuberculosis cultures from respiratory samples were sterile after 6 weeks of therapy. Three patients have clinical and microbiological cure of tuberculosis with a combination regimen with linezolid (range: 5-24 months). One patient was lost to follow-up at month 5. The remaining patient has completed 11 months of therapy and is still on treatment. Four patients developed anaemia and needed blood transfusions. In two of these patients, the linezolid daily-dose (600 mg twice a day) was successfully reduced to 50% (300 mg twice a day) to decrease toxicity while maintaining efficacy. Peripheral neuropathy (two patients) and pancreatitis (one patient) were other adverse events observed during linezolid treatment. CONCLUSIONS: In our experience, linezolid has been a valid alternative drug in the management of multidrug-resistant tuberculosis. The prolonged use of linezolid is frequently associated with toxicity, mainly anaemia and peripheral neuropathy, that requires special management.

ABSTRACT

Liver transplantation is being evaluated as a therapeutic option for human immunodeficiency virus (HIV)-infected patients with end-stage liver disease, but experience is still scarce. We describe the outcome of 4 HIV-infected patients who underwent liver transplantation in our hospital between July 2002 and April 2003. HIV-infected liver transplant recipients meet the same standard criteria for transplantation as do HIV-negative candidates. In addition, HIV infected persons are required to have a CD4 T-cell count greater than 100/mL (CD4 T-cells are targets for HIV infection). Immunosuppressive regimens, perioperative surgical prophylaxis, and prophylaxis for opportunistic infections are standard in the Liver Transplantation Unit in our hospital. Four patients, including 3 former intravenous drug users, received a liver transplant (2 from deceased donors and 2 from living donors), with a median follow-up of 510 days. Three patients (75%) are alive, with 1 death occurring 17 months posttransplantation in a patient who developed fibrosing cholestatic hepatitis. Rejection occurred in 1 patient, and was managed with no complications. Hepatitis C virus (HCV) recurrence occurred in 3 patients. HIV-infection has remained under control with antiretroviral treatment. A combination of 3 nucleoside analogs was used in 3 patients, with no need for drug adjustments. No opportunistic infections or other significant infectious complications developed. In conclusion, orthotopic liver transplantation seems a safe therapeutic option in the short term for HIV-infected persons with end stage liver disease, including patients with a history of drug abuse. If indicated, an antiretroviral regimen consisting of 3 nucleosides could be used to avoid interactions with immunosuppressive drugs.
