Multicenter Study Comparative Study
Cryptococcal immune reconstitution inflammatory syndrome after antiretroviral therapy in AIDS patients with cryptococcal meningitis: a prospective multicenter study.
A prospective multicenter study of cryptococcal immune reconstitution inflammatory syndrome (IRIS) was conducted as a substudy of the Bacteriology and Mycology Study Group 3-01. Of 101 AIDS patients with cryptococcal meningitis who received highly active antiretroviral therapy (HAART), 13 experienced cryptococcal IRIS. No association between the timing of HAART initiation and the diagnosis of IRIS was identified. Increased baseline serum cryptococcal antigen (CrAg) titer was a risk factor for cryptococcal IRIS.

Randomized Controlled Trial Multicenter Study Comparative Study
Initial low-dose gentamicin for Staphylococcus aureus bacteremia and endocarditis is nephrotoxic.
The safety of adding initial low-dose gentamicin to antistaphylococcal penicillins or vancomycin for treatment of suspected Staphylococcus aureus native valve endocarditis is unknown. This study evaluated the association between this practice and nephrotoxicity. ⋯ Initial low-dose gentamicin as part of therapy for S. aureus bacteremia and native valve infective endocarditis is nephrotoxic and should not be used routinely, given the minimal existing data supporting its benefit.

With use of data from the Prospective Antifungal Therapy (PATH) Alliance registry, we performed this multicenter, prospective, observational study to assess the epidemiologic characters and outcomes of invasive fungal infection (IFI) in hematopoietic stem cell transplant (HSCT) recipients. ⋯ IA remains the most commonly identified IFI among HSCT recipients, but rates of survival in persons with IA appear to have improved, compared with previously reported data. Invasive candidiasis and IFI due to molds other than Aspergillus species remain a significant problem in HSCT recipients.

High rates of resistance to trimethoprim-sulfamethoxazole (TMP-SMX) among uropathogenic Escherichia coli are recognized, and concerns exist about emerging fluoroquinolone resistance. ⋯ These results suggest that the prevalence of TMP-SMX-resistant infection among patients with uncomplicated pyelonephritis is > or =20% in many areas of the United States, and risk stratification cannot identify patients at low risk of infection. Rates of fluoroquinolone-resistant E. coli infection appear to be low among patients with uncomplicated pyelonephritis but higher among those with complicated infections. Fluoroquinolones should remain to be the preferred empirical treatment for women with uncomplicated pyelonephritis.

Randomized Controlled Trial Multicenter Study Comparative Study
Single-day, patient-initiated famciclovir therapy versus 3-day valacyclovir regimen for recurrent genital herpes: a randomized, double-blind, comparative trial.
Recurrent genital herpes is a major problem for patients worldwide. Early episodic treatment with short-course therapy is effective, often stopping progression of outbreaks. This study is the first head-to-head comparison of single-day famciclovir (1000 mg administered twice daily) versus 3-day valacyclovir (500 mg administered twice daily) for episodic therapy in immunocompetent patients. ⋯ Single-day famciclovir (1000 mg administered twice daily) was similar to 3-day valacyclovir (500 mg administered twice daily) in both efficacy and safety, representing a more convenient treatment for immunocompetent adults with recurrent genital herpes.
