Curran, M.D., M.P.H. 1993 Revised Classification System for HIV Infection and Expanded Surveillance Case Definition for AIDS Among Adolescents and Adults Summary CDC has revised the classification system for HIV infection to emphasize the clinical importance of the CD4+ T-lymphocyte count in the categorization of HIV-related clinical conditions. This classification system replaces the system published by CDC in 1986 (1) and is primarily intended for use in public health practice. Consistent with the 1993 revised classification system, CDC has also expanded the AIDS surveillance case definition to include all HIV-infected persons who have less than 200 CD4+ T-lymphocytes/uL, or a CD4+ T-lymphocyte percentage of total lymphocytes of less than 14. This expansion includes the addition of three clinical conditions

EASL 2017 Clinical Practice Guidelines on the management of hepatitis B virus infection.

Background Infliximab is a humanized antibody against tumor necrosis factor α (TNF-α) that is used in the treatment of Crohn's disease and rheumatoid arthritis. Approximately 147,000 patients throughout the world have received infliximab. Excess TNF-α in association with tuberculosis may cause weight loss and night sweats, yet in animal models it has a protective role in the host response to tuberculosis. There is no direct evidence of a protective role of TNF-α in patients with tuberculosis. Methods We analyzed all reports of tuberculosis after infliximab therapy that had been received as of May 29, 2001, through the MedWatch spontaneous reporting system of the Food and Drug Administration. Results There were 70 reported cases of tuberculosis after treatment with infliximab for a median of 12 weeks. In 48 patients, tuberculosis developed after three or fewer infusions. Forty of the patients had extrapulmonary disease (17 had disseminated disease, 11 lymph-node disease, 4 peritoneal disease, 2 pleural dis...

Tuberculosis associated with infliximab, a tumor necrosis factor alpha-neutralizing agent

To the Editor—We appreciate the comments by Fe Talento et al regarding our article evaluating the rate of effective empirical therapy for mefhicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections. Fe Talento et al comment on the success of an integrated clinical microbiology service at Beaumont Hospital in Dublin, Ireland. This service is led by specially trained clinical microbiologists who communicate with the attending physician of each patient who has a positive blood culture result and provide recommendations for further evaluation and treatment. The authors note that, with use of this system, 80 of 83 patients with bloodstream infection due to MRSA received antibiotics. Of these 80 patients, 91% received appropriate antibiotics within the first 24 hours after the initial blood culture isolate was identified as suspected S. aureus. Three patients received no antibiotics and were not included in this calculation. Fe Talento and colleagues report that this rate is much higher than the rate of appropriate therapy reported in our study. Although the success of this program is laudable, the authors' comparison is not accurate: Fe Talento et al judged appropriateness of treatment on the basis of antibiotics given after a blood culture result had first been noted to be positive and after S. aureus had been suspected as a pathogen (presumably after gram-positive cocci were identified as pathogens in the blood culture). In our study, appropriateness was judged on the basis of antibiotics administered on the day that the blood culture specimen was obtained—often days before the blood culture result was even known to be positive. For a more appropriate comparison, we suggest that Fe Talento and colleagues analyze the appropriateness of therapy on the day that blood samples for culture were obtained and not the day that a positive culture result was obtained. We agree that communication between the microbiology laboratory and treating clinicians is an important tool to improve rates of effective antimicrobial therapy, and having an integrated clinical microbiology service is a wonderful asset (although it is probably not feasible in many community hospitals in the United States, the majority of which have less than 250 beds). Rapid diagnostic methods, such as polymerase chain reaction testing and culture on selective media (eg, CHROMagar; Becton Dickinson), are additional tools that can be used to assist with early identification of organisms once culture results turn positive to improve rates of effective antimicrobial therapy.

Inside-out: the changing epidemiology of methicillin-resistant Staphylococcus aureus.

To assess the association of illicit drug use and USA300 methicillin-resistant Staphylococcus aureus (MRSA) bacteremia, a multicenter study was conducted at 4 Veterans Affairs medical centers during 2004-2008. The study showed that users of illicit drugs were more likely to have USA300 MRSA bacteremia (in contrast to bacteremia caused by other S. aureus strains) than were patients who did not use illicit drugs (adjusted relative risk 3.0; 95% confidence interval 1.9-4.4). The association of illicit drug use with USA300 MRSA bacteremia decreased over time (p = 0.23 for trend). Notably, the proportion of patients with USA300 MRSA bacteremia who did not use illicit drugs increased over time. This finding suggests that this strain has spread from users of illicit drugs to other populations.
