Background: Systems for quality and safety assurance in organ donation and transplantation are vital, especially those that seek to minimize donor disease transmission. Australia has developed a national vigilance and surveillance system to identify, review, and analyze actual and potential donor-derived infections and other disease transmissions.

Methods: The system involves notification of incidents to the Australian Organ and Tissue Authority for review by a Vigilance and Surveillance Expert Advisory Committee (VSEAC).

Coronavirus-19 (COVID-19) mortality rates among haemopoietic stem cell transplant (HSCT) patients are high, ranging between 20% and 40%. We prospectively evaluated the mortality outcomes of COVID-19 in Western Australian HSCT patients. A total of 32/492 (6.

We transplanted six solid organs from three hepatitis C virus (HCV) polymerase chain reaction (PCR)-positive donors during 2018-2023. Recipients were treated with glecaprevir/pibrentasvir or sofosbuvir/velpatasvir for 4-12 weeks, with all six achieving sustained virological response without significant adverse events. As occurs in other jurisdictions, solid organ transplants from HCR PCR-positive donors can be safely utilised in Australia.

Background: Western Australia (WA) serves as a unique global case study on the impact of coronavirus disease 2019 (COVID-19) on an isolated, prepared and highly vaccinated population. This study builds upon the study performed by House et al. through an extended data set.

Patients can be immunocompromised from a diverse range of disease and treatment factors, including malignancies, autoimmune disorders and their treatments, and organ and stem-cell transplantation. Infections are a leading cause of morbidity and mortality in immunocompromised patients, and the disease treatment landscape is continually evolving. Despite being a critical but preventable and curable adverse event, the reporting of infection events in randomised trials lacks sufficient detail while inconsistency of categorisation and definition of infections in observational and registry studies limits comparability and future pooling of data.

Background: Cytomegalovirus (CMV) is a common cause of morbidity after allogeneic haematopoietic cell transplantation (alloHCT). Pre-emptive therapy (PET) with valganciclovir (VGC) is associated with haematological toxicity.

Methods: We included alloHCT patients from 2018 to 2021 where letermovir (LTV) was used for CMV PET because of cytopenias.

Background: Western Australia (WA) was in a unique position to experience coronavirus disease 2019 (COVID-19) in a highly vaccinated and geographically isolated population.

Aim: To describe the COVID-19 Omicron experience at the only quaternary hospital in WA following border opening from 3 March to 11 May 2022.

Participants: A total of 158 adults with microbiologically confirmed COVID-19 were admitted to the respiratory or intensive care unit (ICU).

Background: The global COVID-19 pandemic disproportionately affected certain populations and its management differed between countries. This national study describes characteristics and outcomes of COVID-19 in patients with cancer in Australia.

Methods: We performed a multicentre cohort study of patients with cancer and COVID-19 from March 2020 to April 2022.

Hyperammonemia syndrome (HS) is a life-threatening condition occurring in solid organ transplant patients, affecting primarily lung recipients, and is associated with and/or spp infection. The organ donor was a young man who died of hypoxic brain injury and had urethral discharge antemortem. The donor and 4 solid organ transplant recipients had infection with and/or spp.

Anterior uveitis is a reported complication of intravenous cidofovir, almost exclusively described in human immunodeficiency virus (HIV) infected patients treated for cytomegalovirus retinitis. In this study, we report the case of an allogeneic stem cell transplant recipient with significant visual impairment and hypotony following administration of high-dose intravenous cidofovir for hemorrhagic cystitis due to BK virus.

We aimed to study COVID-19 infection in healthcare workers (HCWs) during the first wave in a setting of low community incidence prior to HCW vaccination. We performed a cross-sectional study of frontline HCWs in two tertiary hospitals in Western Australia with questionnaire and testing for SARS-CoV-2 IgG antibodies, using a screening assay followed by confirmatory assays for initial reactive results. 799 Frontline HCWs were enrolled in the study, working in the emergency department (n = 194, 24.

High-throughput diagnostic assays are required for large-scale population testing for severe acute respiratory coronavirus 2 (SARS-CoV-2). The gold standard technique for SARS-CoV-2 detection in nasopharyngeal swab specimens is nucleic acid extraction followed by real-time reverse transcription-PCR. Two high-throughput commercial extraction and detection systems are used routinely in our laboratory: the Roche cobas SARS-CoV-2 assay (cobas) and the Roche MagNA Pure 96 system combined with the SpeeDx PlexPCR SARS-CoV-2 assay (Plex).

Background: Antifungal administration via outpatient parenteral antimicrobial therapy (OPAT) is infrequent. As patients with invasive fungal infections (IFIs) receiving OPAT are at high risk of readmissions, careful, risk-based patient selection and monitoring is important.

Objectives: To describe our experience managing IFIs via OPAT, including assessment of risk factors associated with unplanned readmissions.

Context/objective: Prevention of urinary tract infection (UTI) after spinal cord injury is an important goal. Intravesical hyaluronic acid with chondroitin sulphate (HA+CS) has been effective in preventing UTI in other settings. We aimed to demonstrate safety and feasibility of a standard treatment course of 7 intravesical HA+CS instillations over 12 weeks, in patients with acute (Arm A) and chronic (Arm B) spinal cord injury (SCI).

Internationally, the designation of a patient as an increased viral risk organ donor has been associated with lower utilisation rates. The actual prevalence of blood borne viruses in Australian potential organ donors, and the predictive performance of questionnaires administered to stratify this risk, remains unknown. We conducted a retrospective review of all patients who commenced workup for donation on the national database between 2014-2020.

SARS-CoV-2 viral load declines from the time of symptom onset; in some studies viral load is higher or persists longer in more severe COVID-19 infection, and viral load correlates with culture positivity. This was a retrospective cohort study of inpatients and outpatients during the first wave of COVID-19 infection in Western Australia, March to May 2020, of the relationship of SARS-CoV-2 viral load (using the First WHO International Standard for SARS-CoV-2 RNA) from symptom onset, by clinical subgroups determined from the public health database and hospital records, using regression analysis. We studied 320 samples from 201 COVID-19 cases: 181 mild, seven severe, 11 critical, and four cases who died (two were also critical cases).
