Hospital-based antibiotic use in patients with Mycobacteriumaviumcomplex Treatment guidelines exist for pulmonary Mycobacteriumaviumcomplex (MAC) infection, although studies suggest poor concordance in clinician practice. Using a national database including hospital encounters of laboratory-confirmed MAC patients, we sought to characterise US treatment practices. We assessed patients in the Premier Healthcare Database from 2009 to 2013 with two or more MAC-positive cultures or one MAC
Serodiagnosis of Mycobacteriumavium-complex pulmonary disease using an enzyme immunoassay kit The diagnosis of Mycobacteriumavium-complex pulmonary disease (MAC-PD) and/or its discrimination from pulmonary tuberculosis (TB) is sometimes complicated and time consuming.We investigated in a six-institution multicenter study whether a serologic test based on an enzyme immunoassay (EIA) kit was useful for diagnosing MAC-PD and for distinguishing it from other lung diseases.An EIA kit detecting
Successful discontinuation of therapy for disseminated Mycobacteriumaviumcomplex infection after effective antiretroviral therapy. Highly active antiretroviral therapy (HAART) is associated with improvement or resolution of several HIV-associated opportunistic infections. Although prophylaxis against disseminated Mycobacteriumaviumcomplex infection may be successfully discontinued after a favorable response to HAART, the 1999 guidelines from the U.S. Public Health Service/Infectious (...) Diseases Society of America recommend continuing therapy for disseminated M. aviumcomplex infection, regardless of the response to HAART.To examine the outcome among patients with disseminated M. aviumcomplex infection whose antimycobacterial therapy was discontinued after a favorable response to HAART.Retrospective chart review between May 2000 and May 2001.13 Canadian HIV clinics.52 HIV-infected adults (43 men; mean age, 37.3 years) in whom successful antimycobacterial therapy for disseminated M
Discontinuation of prophylaxis for Mycobacteriumaviumcomplex disease in HIV-infected patients who have a response to antiretroviral therapy. Terry Beirn Community Programs for Clinical Research on AIDS. Several agents are effective in preventing Mycobacteriumaviumcomplex disease in patients with advanced human immunodeficiency virus (HIV) infection. However, there is uncertainty about whether prophylaxis should be continued in patients whose CD4+ cell counts have increased substantially (...) with antiviral therapy.We conducted a multicenter, double-blind, randomized trial of treatment with azithromycin (1200 mg weekly) as compared with placebo in HIV-infected patients whose CD4+ cell counts had increased from less than 50 to more than 100 per cubic millimeter in response to antiretroviral therapy. The primary end point was M. aviumcomplex disease or bacterial pneumonia.A total of 520 patients entered the study; the median CD4+ cell count at entry was 230 per cubic millimeter. In 48 percent

A randomized trial of clarithromycin as prophylaxis against disseminated Mycobacteriumaviumcomplex infection in patients with advanced acquired immunodeficiency syndrome. Disseminated infection with Mycobacteriumaviumcomplex is the most common opportunistic infection in patients with advanced stages of the acquired immunodeficiency syndrome (AIDS). We studied the efficacy and safety of prophylactic treatment with clarithromycin, a macrolide antibiotic.We conducted a randomized, placebo (...) -controlled, double-blind study of clarithromycin in patients with AIDS in the United States and Europe. Entry criteria included blood cultures that were negative for M. aviumcomplex, a Karnofsky performance score of 50 or higher, a CD4 cell count of 100 or less per cubic millimeter, and a life expectancy of at least six months.After the first interim analysis, the study was stopped. M. aviumcomplex infection developed in 19 of the 333 patients (6 percent) assigned to clarithromycin and in 53 of the 334
A comparison of two regimens for the treatment of Mycobacteriumaviumcomplex bacteremia in AIDS: rifabutin, ethambutol, and clarithromycin versus rifampin, ethambutol, clofazimine, and ciprofloxacin. Canadian HIV Trials Network Protocol 010 Study Group. Bacteremia with the Mycobacteriumaviumcomplex is common in patients with the acquired immunodeficiency syndrome (AIDS), but the most effective treatment for this infection remains unclear.We randomly assigned 229 patients with AIDS and M (...) . aviumcomplex bacteremia to receive either rifampin (600 mg daily), ethambutol (approximately 15 mg per kilogram of body weight daily), clofazimine (100 mg daily), and ciprofloxacin (750 mg twice daily) (the four-drug group) or rifabutin (600 mg daily), ethambutol (as above), and clarithromycin (1000 mg twice daily) (the three-drug group). In the three-drug group the dose of rifabutin was reduced by half after 125 patients were randomized, because 24 of 63 patients had uveitis.Among 187 patients who
Prophylaxis against disseminated Mycobacteriumaviumcomplex with weekly azithromycin, daily rifabutin, or both. California Collaborative Treatment Group. Azithromycin is active in treating Mycobacteriumaviumcomplex disease, but it has not been evaluated as primary prophylaxis in patients with human immunodeficiency virus (HIV) infection. Because the drug is concentrated in macrophages and has a long half-life in tissue, there is a rationale for once-weekly dosing.We compared three (...) prophylactic regimens in a multicenter, double-blind, randomized trial involving 693 HIV-infected patients with fewer than 100 CD4 cells per cubic millimeter. The patients were assigned to receive rifabutin (300 mg daily), azithromycin (1200 mg weekly), or both drugs. They were monitored monthly with blood cultures for M. avium complex.In an intention-to-treat analysis, the incidence of disseminated M. aviumcomplex infection at one year was 15.3 percent with rifabutin, 7.6 percent with azithromycin
Two controlled trials of rifabutin prophylaxis against Mycobacteriumaviumcomplex infection in AIDS. Disseminated Mycobacteriumaviumcomplex infection eventually develops in most patients with the acquired immunodeficiency syndrome (AIDS). This infection results in substantial morbidity and reduces survival by about six months.We conducted two randomized, double-blind, multicenter trials of daily prophylactic treatment with either rifabutin (300 mg) or placebo. All the patients had AIDS (...) and CD4 cell counts < or = 200 per cubic millimeter. The primary end point was M. aviumcomplex bacteremia as assessed monthly by blood culture. The secondary end points were signs and symptoms associated with disseminated M. aviumcomplex infection, adverse events, hospitalization, and survival.In the first trial, M. aviumcomplex bacteremia developed in 51 of 298 patients (17 percent) assigned to placebo and 24 of 292 patients (8 percent) assigned to rifabutin (P < 0.001). In the second trial
