The Clinical Impact of Antibiotic Allergy Labels on One‐Year Outcomes of Solid Organ Transplant Recipients Antibiotic allergy labels (AALs) are common and often incorrect. They have many potential impacts, including the use of broader-spectrum antibiotics and suboptimal treatment of infections. The impact....

New research from our faculty: antibiotic allergy labels in transplant patients are linked to C. diff infections, more antibiotic use & longer hospital stays, and they may be preventable. 🔬 #IDSky #MedSky

Results: ✅ Inpatient initiation is non-inferior, safe and feasible. ✅ Higher completion: 76% completion in the inpatient group vs. 66% in the outpatient group. ✅ Safety: Adverse events were similar across both groups, though grade 4 anemia was actually less frequent in the inpatient group.

Inpatient initiation of tuberculosis preventive therapy with 1 month of isoniazid and rifapentine for adults with advanced HIV disease and cryptococcal meningitis (IMPROVE): a non-inferiority, randomi... 1HP initiation before hospital discharge was non-inferior to outpatient initiation among adults with AHD and cryptococcosis. These data suggest that following exclusion of active tuberculosis disease,...

Can we improve TB preventive therapy (TPT) for those with advanced HIV? 🏥

A new phase-3 trial from @drboulware.bsky.social and colleagues evaluated two strategies for the 1-month 1HP (rifapentine + isoniazid) regimen in patients with cryptococcal meningitis. #IDSky

Immediate or high-dose antituberculosis therapy for HIV-related sepsis in Tanzania and Uganda (ATLAS): a phase 3, open-label, randomised, controlled, 2 × 2 factorial, superiority trial Among all participants with HIV-related sepsis, 28-day mortality was not significantly reduced with immediate or high-dose antituberculosis therapy. In the subgroup with later confirmed tuberculosis, ...

ATLAS trial by faculty Dr. David Boulware and colleagues, studied TB treatment timing in people with HIV & sepsis in East Africa. Overall mortality unchanged, but early standard-dose TB therapy saved lives in confirmed TB cases. #IDSky #MedSky

Faculty research spotlight: Dr. Rajasingham and colleagues studied point-of-care CD4 testing for advanced HIV in Uganda. Visitect CD4 enabled faster ART initiation with similar 24-week survival and retention-in-care at comparable cost. #IDSky

Faculty highlight: Dr. Dimitri Drekonja and colleagues conducted a study showing AI can streamline infection surveillance after cardiac device procedures—reducing chart review time from ~25 to 5–7 minutes, with excellent accuracy and needed human oversight. #IDSky #AI

Headache as a predictor of cryptococcal meningitis in ambulatory patients with symptomatic HIV-associated cryptococcal antigenemia AbstractBackground. People with HIV-associated cryptococcal antigenemia are at high risk for meningitis and death. In resource-limited settings, lumbar pun

New faculty research in @ofidjournal.bsky.social shows that headache plus high plasma CrAg titer is the strongest predictor of cryptococcal meningitis in people with HIV. When titers are unavailable, combining neurologic symptoms improves triage decisions. #IDSky #MedSky

@drboulware.bsky.social and team tracked plasma cryptococcal antigen titers over time. Median titers in advanced HIV showed a modest, non-significant upward trend, while the proportion on ART declined.

Dr. @dimitridrekonja.bsky.social and colleagues examined inappropriate antimicrobial use after cardiac device procedures.

P-90. Microbiology of Spinal Fusion Infections: An Analysis of the National Healthcare Safety Network Database AbstractBackground. Understanding the current microbial causes of surgical site infections (SSIs) following spinal fusion surgeries is essential for guidin

Using cases reported to the National Healthcare Safety Network, Dr. Tai and team analyzed more than 5,000 spinal fusion surgical site infections from 2021–2022 to better understand the role of gram-negative organisms.

University of Minnesota Infectious Diseases researchers presented multiple abstracts at #IDWeek2025, spanning antimicrobial stewardship, global health, and orthopedic infections. Proud of our faculty and trainees. #IDSky

Induction Regimens and Kidney Re‐Transplant Outcomes after BK Nephropathy–Related Graft Loss: A U.S. Cohort Study This study investigated the association between induction type and long-term outcomes in kidney retransplant recipients who experienced graft loss due to BK virus–associated nephropathy (BKVAN).

A late reflection on @idweek.bsky.social , but a memorable start to the meeting. The opening plenary with Drs. Michael Osterholm and Ruth Lynfield set the tone on preparedness, public trust, and why public health partnerships matter. #IDSky

Prolonged antibiotic therapy for spinal implant infection may not improve outcomes ATLANTA — Results presented at IDWeek showed prolonged antibiotic therapy beyond 12 weeks may not improve outcomes for early postoperative spinal implant infections.“Shorter, standardized ...

Prolonged antibiotics may not improve outcomes in early spinal implant infections. At IDWeek, SPIRIT researchers showed no benefit to therapy >12 weeks when optimal surgical source control is achieved. #IDSky

Trial of High-Dose Oral Rifampin in Adults with Tuberculous Meningitis | NEJM Tuberculous meningitis is often lethal, and many survivors have disabilities despite antimicrobial treatment and adjunctive glucocorticoid therapy. Standard-dose rifampin has limited central nervou...

High-dose rifampin did not improve survival in adult tuberculous meningitis. In a trial across 3 countries, 6-month mortality was similar to standard dosing, with more liver injury at higher doses. Important evidence for TB care from @natebahrid.bsky.social @drboulware.bsky.social . #IDSky
