We compared outcomes at 3 community hospitals before and after switching from in-person to a Tele-ID group from an academic medical center. Compared to in-person, Tele-ID received significantly more consultations with similar outcomes for length of hospital stay, transfers, readmission, and mortality. Tele-ID is a suitable alternative for community settings.

Background: Lack of on-site antimicrobial stewardship expertise is a barrier to establishing successful programs. Tele-antimicrobial stewardship programs (TASPs) utilizing a clinical decision support system (CDSS) can address these challenges.

Methods: This interrupted time series study reports the impact of CDSS implementation (February 2020) within an existing TASP on antimicrobial usage in a community hospital.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has revolutionized the practice of ambulatory medicine, triggering rapid dissemination of digital healthcare modalities, including synchronous video visits. However, social determinants of health, such as age, race, income, and others, predict readiness for telemedicine and individuals who are not able to connect virtually may become lost to care. This is particularly relevant to the practice of infectious diseases (ID) and human immunodeficiency virus (HIV) medicine, as we care for high proportions of individuals whose health outcomes are affected by such factors.

Infectious Diseases (ID) specialists pride themselves on performing a thorough history and physical exam, and developing a comprehensive diagnosis and management plan. A timely question is whether this tradition is at risk from the coming wave of telemedicine in clinical practice? It would not be if ID specialists embrace the changes ahead and leverage new technologies to enhance the efficiency and reach of their clinical practices. In this report, we highlight the opportunities and challenges offered by telemedicine for ID practice (Table 1).

Background: Extensively drug-resistant Acinetobacter baumannii (XDR-Ab) has emerged as a major nosocomial pathogen, but optimal treatment regimens are unknown. Although solid organ transplant (SOT) recipients are particularly susceptible to XDR-Ab infections, studies in this population are limited. Our objectives were to determine the epidemiology, clinical characteristics and outcomes of XDR-Ab infections among SOT patients.

Background: Staphylococcus aureus infections among lung transplant recipients are poorly studied.

Methods: We conducted a 5-year retrospective study of the epidemiology, clinical manifestations, risk factors, and outcomes of patients infected with S aureus within the first 90 days after lung transplantation.

Results: An S aureus infection developed in 109 of 596 lung transplant (18%) recipients.

Between 2000 and 2011, proven or probable invasive aspergillosis (IA) was diagnosed in 1.7% (8/455) of heart transplant (HTx) recipients at our center, in the absence of antifungal prophylaxis. All patients had invasive pulmonary infections and 75% (6/8) were diagnosed during 2 separate 3-month periods.

Immunity against cytomegalovirus (CMV) is initiated after its recognition by Toll-like receptor 2 (TLR2). We assessed the association between a single-nucleotide polymorphism (SNP) that impairs TLR2 function and CMV disease in a cohort of 737 liver recipients. Ninety-two of 737 patients (7.

Background: Toll-like receptor 4 (TLR4) is the main immune molecule that recognizes lipopolysaccharide from gram-negative bacteria. Single-nucleotide polymorphisms (SNPs) in the TLR4 gene that impair lipopolysaccharide recognition may influence gram-negative bacterial infections after liver transplantation.

Methods: TLR4 D299G and T399I SNPs were assessed in a cohort of 706 liver transplant recipients and were associated with the clinical characteristics and outcome of gram-negative bacterial infections.

Toll-like receptor 2 (TLR2) is an immune sensor for gram-positive bacterial cell wall components. Single-nucleotide polymorphisms (SNPs) in the TLR2 gene that impair its function may, therefore, influence the risk and outcomes of gram-positive bacterial infections. In a cohort of 694 liver transplant recipients, we assessed the TLR2 SNP that is translated into an amino acid substitution of arginine for glutamine at position 753 (R753Q), and we found that its presence was associated with the clinical characteristics and outcomes of gram-positive bacterial infections.

Bacteremia is a significant cause of morbidity and mortality after liver transplantation. The characterization of the microbiological spectrum of bacteremia after liver transplantation may help physicians in choosing the initial empirical antimicrobial therapy for patients presenting with sepsis. The clinical and microbiology records of patients who received liver transplantation from January 1997 to March 2006 were reviewed.

Human herpesvirus 6 (HHV-6) infections occur in > 95% of humans. Primary infection, which occurs in early childhood as an asymptomatic illness or manifested clinically as roseola infantum, leads to a state of subclinical viral persistence and latency. Reactivation of latent HHV-6 is common after liver transplantation, possibly induced and facilitated by allograft rejection and immunosuppressive therapy.
