Prophylactic trimethoprim/sulfamethoxazole (TMP/SMX) prevents Pneumocystis jirovecii pneumonia and nocardiosis in immunocompromised patients but sometimes is avoided because of purported allergies or ...side effects. Of 25 immunocompromised patients receiving alternative prophylaxis in whom nocardiosis developed, 16 subsequently tolerated TMP/SMX treatment. Clinicians should consider TMP/SMX allergy evaluation and rechallenging to assess patient tolerance.

Abstract
Background
The coronavirus disease 2019 (COVID-19) pandemic has led to significant reductions in transplantation, motivated in part by concerns of disproportionately more severe disease ...among solid organ transplant (SOT) recipients. However, clinical features, outcomes, and predictors of mortality in SOT recipients are not well described.
Methods
We performed a multicenter cohort study of SOT recipients with laboratory-confirmed COVID-19. Data were collected using standardized intake and 28-day follow-up electronic case report forms. Multivariable logistic regression was used to identify risk factors for the primary endpoint, 28-day mortality, among hospitalized patients.
Results
Four hundred eighty-two SOT recipients from >50 transplant centers were included: 318 (66%) kidney or kidney/pancreas, 73 (15.1%) liver, 57 (11.8%) heart, and 30 (6.2%) lung. Median age was 58 (interquartile range IQR 46–57), median time post-transplant was 5 years (IQR 2–10), 61% were male, and 92% had ≥1 underlying comorbidity. Among those hospitalized (376 78%), 117 (31%) required mechanical ventilation, and 77 (20.5%) died by 28 days after diagnosis. Specific underlying comorbidities (age >65 adjusted odds ratio aOR 3.0, 95% confidence interval CI 1.7–5.5, P < .001, congestive heart failure aOR 3.2, 95% CI 1.4–7.0, P = .004, chronic lung disease aOR 2.5, 95% CI 1.2–5.2, P = .018, obesity aOR 1.9, 95% CI 1.0–3.4, P = .039) and presenting findings (lymphopenia aOR 1.9, 95% CI 1.1–3.5, P = .033, abnormal chest imaging aOR 2.9, 95% CI 1.1–7.5, P = .027) were independently associated with mortality. Multiple measures of immunosuppression intensity were not associated with mortality.
Conclusions
Mortality among SOT recipients hospitalized for COVID-19 was 20.5%. Age and underlying comorbidities rather than immunosuppression intensity-related measures were major drivers of mortality.
In this analysis of 482 solid organ transplant recipients with coronavirus disease 2019 (COVID-19), the authors report 28-day mortality of 20.5% among inpatients, strongly associated with age and comorbidities, and conclude that this is comparable to rates observed in the general population.
Invasive aspergillosis (IA) is a serious fungal infection that primarily affects patients with prolonged and profound neutropenia, and compromised cell-mediated immunity. Aspergillosis of the ...oesophagus and gastrointestinal tract is uncommon but seen in advanced cases of disseminated IA. However, it is difficult to diagnose antemortem due to the poor specificity of the symptoms and the absence of characteristic imaging findings. Therefore, the reported cases of gastrointestinal aspergillosis have been associated with high morbidity and mortality, and frequently diagnosed postmortem. Here we present a successful outcome in a patient with relapsed and refractory multiple myeloma who had presented with febrile neutropenia, cough and dysphagia, and was diagnosed with disseminated IA comprising of pulmonary and oesophageal involvement. This case highlights the need for a high index of suspicion and the importance of invasive procedures for histopathology and molecular diagnostics to ensure an early diagnosis and therapeutic intervention.

We evaluated our hospital-wide BLA protocol (BLA-P) that used following categories: intolerance, low-risk, and high-risk.Hospitalized adult patients with listed BLA during 10/2021-12/2022 were eligible. Exclusions were critically ill, surgical, hospice or comfort care, or non-verbal patients. Assessment was counted each time a pharmacist evaluated BLA. Interventions were no further action (high-risk allergy, patient refusal, unstable clinical status), updated allergy label, or delabeled. Delabeling was done either based on antibiotic history (direct-delabeling), or via test-dose challenge for low-risk patients.

Purpose
Diabetes mellitus (DM) is common among recipients of heart transplantation (HTx) but its impact on clinical outcomes is unclear. We evaluated the associations between pretransplant DM and ...posttransplant DM (PTDM) and outcomes among adults receiving HTx at a single center.
Methods
We performed a retrospective study (range 01/2008 – 07/2018), n = 244. The primary outcome was survival; secondary outcomes included acute rejection, cardiac allograft vasculopathy, infection requiring hospitalization, macrovascular events, and dialysis initiation post‐transplant. Comparisons were performed using Kaplan‐Meier and multivariable Cox regression analyses.
Results
Pretransplant DM was present in 75 (30.7%) patients and was associated with a higher risk for infection requiring hospitalization (p < 0.05), but not with survival or other outcomes. Among the 144 patients without pretransplant DM surviving to 1 year, 29 (20.1%) were diagnosed with PTDM at the 1‐year follow‐up. After multivariable adjustment, PTDM diagnosis at 1‐year remained associated with worse subsequent survival (hazard ratio 2.72, 95% confidence interval 1.03‐7.16). Predictors of PTDM at 1‐year included cytomegalovirus seropositivity and higher prednisone dose (> 5 mg/day) at 1‐year follow‐up.
Conclusions
Compared to HTx recipients without baseline DM, those with baseline DM have a higher risk for infections requiring hospitalization, and those who develop DM after HTx have worse survival.

Advances in solid organ transplantation have improved the survival of end‐stage organ disease at the expense of an increased risk for opportunistic infections. Unusual clinical presentations and the ...possibility of concurrent infections make diagnosing invasive fungal infection (IFI) more difficult. Here, we present a case of simultaneous vertebral infection caused by Coccidioides immitis‐posadasii and subcutaneous phaeohyphomycosis due to Nigrograna mackinnonii in a kidney transplant recipient. The diagnosis of both infections required invasive procedures to obtain tissue and a high index of suspicion that more than one IFI could be present. A multidisciplinary team approach for the management of immunocompromised patients with suspected or diagnosed IFI is warranted.

BACKGROUND.Heart transplantation is a life-saving procedure that has seen improvements in transplant and patient outcomes due to advances in immunosuppression and prevention of posttransplantation ...infectious episodes (IEps). This study systematically evaluates IEps in the modern era of heart transplantation at Stanford University Medical Center.
METHODS.This is a single-center retrospective review that includes 279 consecutive adult heart transplantation recipients from January 2008 to September 2017. Baseline demographic, clinical, serological, and outcomes information were collected. Kaplan-Meier estimator was used to assess survival stratified by IEp occurrence within the first year.
RESULTS.A total of 600 IEps occurred in 279 patients (2.15 IEps per patient) during a median follow-up period of 3 years. Overall survival was 83.3% (95% confidence interval CI, 76.2-88.4) at 1 year posttransplantation for those with any IEp compared with 93.0% (95% CI, 87.2-96.4) in those without IEp (P = 0.07). Bacterial IEps were the most common (n = 375; 62.5%), followed by viral (n = 180; 30.0%), fungal (n = 40; 6.7%), and parasitic (n = 5; 0.8%). IEps by Gram-negative bacteria (n = 210) outnumbered those by Gram-positive bacteria (n = 142). Compared with prior studies from our center, there was a decreased proportion of viral (including cytomegalovirus), fungal (including Aspergillus spp. and non-Aspergillus spp. molds), and Nocardia infections. There were no IEps due to Mycobacterium tuberculosis, Pneumocystis jirovecii, or Toxoplasma gondii.
CONCLUSIONS.A significant reduction in viral, fungal, and Nocardia IEps after heart transplantation was observed, most likely due to advancements in immunosuppression and preventive strategies, including pretransplant infectious diseases screening and antimicrobial prophylaxis.
Background
Incarceration is disruptive to HIV care, often resulting in poor retention in care for people living with HIV (PLWH) after jail release. This gap in HIV care might result in potentially ...preventable emergency department (ED) utilization. We analyzed demographic, incarceration, socioeconomic and clinical data for PLWH released from the Dallas County Jail to the community (1450 incarcerations, 1155 unique individuals) between January 2011 and November 2013.
Results
The study population consisted of predominantly men (77%), with a mean age of 39 years, 67% were black and 14% were Hispanic; half of the releasees visited the ED at least once during the first-year post-jail. In adjusted analyses, female gender, family awareness of HIV status, serious mental illness, and late engagement to HIV care were significantly associated with higher ED utilization. Compared to the general Dallas population, PLWH released from jail had a 5-fold higher proportion of ED visits classified as related to substance use or mental health.
Conclusions
Further efforts are needed to improve the transition from incarceration to community-based HIV care, substance use disorder treatment and mental health services, and to directly address re-engagement in HIV care for out-of-care PLWH who visit the ED.

Introduction
In November 2020, the FDA issued an emergency use authorization (EUA) for monoclonal antibody (mAb) therapy in patients with mild‐to‐moderate COVID‐19 at high risk for disease ...progression.
Methods
We retrospectively reviewed 38 adult hematology patients who received mAbs from 11/2020 to 2/2021.
Results
Thirty (79%) patients received bamlanivimab and 8 (21%) casirivimab‐imdevimab. Four (11%) patients were hospitalized due to COVID‐19, two (5%) progressed to severe disease and one patient (3%) died within 30 days from COVID‐19 disease. Most patients (n = 34, 89%) ultimately tested negative for SARS‐CoV‐2, with 34% (n = 13) clearing the virus within 14 days after mAb infusion. The median time to clearance of viral shedding was 25.5 days (range: 7–138). After mAb infusion, most patients with hematological malignancies (HM) (n = 10/15; 67%) resumed therapy for underlying disease with a median delay of 21.5 days (range: 12–42). We observed a significant difference in hospitalization among patients who received a HCT versus non‐HCT (0% n = 0/26 and 36% n = 4/11, respectively; p < 0.01).
Conclusions
This study demonstrates that SARS‐CoV‐2 specific mAb was safe and may reduce hospitalization compared to what is reported in malignant hematology patients at high risk for disease progression. Our HCT cohort patients had less hospitalization rate compared with HM cohort patients.
