    Abstract Background: Invasive disease caused by airway pathogens, including
    Methods: A retrospective analysis was conducted at a large tertiary Australian health service, comprising multiple centers. Patients aged 18 years or older, in whom the above pathogens were isolated from sterile sites, were included as identified through a microbiology database, between 2015 and 2020. Using electronic medical records, patient demographics, medical history, outcomes of admission, and pathology results were captured and reviewed to address the aims.
    Results: In 252 patients,
    Conclusions: Immunodeficiency is common in this patient population. Screening should be undertaken to ensure timely diagnosis and treatment of the underlying condition to avoid future morbidity and mortality.

    Abstract Coronavirus disease 2019 (COVID-19) in immunocompromised patients can lead to severe and prolonged illness. Data are limited with regard to management of COVID-19 in this setting, particularly in persistent or recrudescent infection. The authors conducted an online survey among infectious diseases doctors to determine current approaches to treatment across Australasia. There was marked variability in responses relating to the diagnostic modalities and use of antiviral agents in patients with immunocompromise, highlighting the need for high-quality studies to guide treatment decisions in this group.

    Abstract Objectives: To evaluate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine acceptance among patients with rheumatic diseases (RMD).
    Methods: All rheumatology patients attending a large suburban health network were invited to participate in an anonymized online survey. The primary outcome of interest was SARS-COV-2 vaccine acceptance.
    Results: The mean (SD) age of respondents (n = 641) was 52.7 (15.1) years and 74.4% (n = 474) were female. Sixty-five percent were willing to have a SARS-COV-2 vaccine, while 34.4% were vaccine-hesitant (unwilling or undecided). On multivariate analysis, vaccine acceptance was associated with smoking (OR: 2.25 [95% CI: 1.22-4.15;
    Conclusion: SARS-COV-2 vaccine hesitancy is prevalent amongst RMD patients and associated with concerns regarding vaccine safety, efficacy, side effects and RMD flare. Clinician recommendation, vaccine choice and communications targeting patient concerns could facilitate vaccine acceptance.

    Abstract Objective: To identify barriers and enablers to COVID-19 vaccination in renal transplant recipients who are undecided about vaccination.
    Methods: An online survey was distributed to 876 adult kidney transplant recipients at a tertiary referral service, who had not been vaccinated against COVID-19. The survey assessed willingness to be vaccinated, attitudes toward COVID-19 vaccines, and barriers and enablers to proceeding with vaccination.
    Results: The survey response rate was 54% (473/876). Three hundred and forty-six (73.1%) participants planned to receive vaccination (yes group), 105 (22.2%) were undecided, and 22 (4.7%) refused vaccination. The undecided group were younger but were not different in other demographic characteristics to the yes group. The undecided group were less positive toward (34.29% vs. 91.3%, p < .001) and more concerned about (93.3% vs. 25.1%, p < .001) vaccination than the yes group. Their concerns related to vaccine safety (including harm to their transplant), poor efficacy, and a lack of rigorous testing in transplant recipients. Undecided recipients had received less vaccine-specific information from medical specialists than the yes group. Most undecided participants (95.1%) were willing to proceed with vaccination with appropriate supports. The most desired supports were information and a recommendation to proceed with vaccination from their treating transplant specialist and team.
    Conclusion(s): Concerns about vaccine safety (including harm to transplant), poor vaccine efficacy, and lack of rigorous testing were barriers to vaccine uptake. Most undecided recipients would proceed with vaccination with specific recommendations and vaccine information provided by their transplant specialist/team. These simple interventions can be readily implemented to optimize vaccine uptake.

    Abstract Objective: The infection risk in patients receiving ibrutinib, idelalisib or venetoclax for chronic lymphocytic leukaemia (CLL) or B-cell lymphoma treated outside of clinical trials is incompletely defined. We sought to identify the severe infection rate and associated risk factors in a 'real-world' cohort.
    Methods: We conducted a retrospective cohort study of adult patients with CLL or lymphoma treated with ibrutinib, idelalisib or venetoclax.
    Results: Of 67 patients identified (ibrutinib n = 53, idelalisib n = 8 and venetoclax n = 6), 32 (48%) experienced severe infection. Severe infection occurred at a rate of 65 infections per 100 person-years, with a median of 17.8 months of therapy. Median time to first infection (IQR) was 5.4 months (1.4-15.9). Poor baseline Eastern Cooperative Oncology Group (ECOG) performance status and high Charlson Comorbidity Index (CCI) score associated with increased risk of severe infection [hazard ratios (95% CI) 1.57 (1.07-2.31, p = .018) and 1.3 (1.05-1.62, p = .016) respectively].
    Conclusion: The severe infection rate for patients receiving ibrutinib, idelalisib or venetoclax for lymphoma and CLL exceeded those reported in clinical trials. Patients with poor ECOG or high CCI should be closely monitored for early signs of infection and prevention strategies actively pursued. Further prospective research is required to define optimal antimicrobial prophylaxis recommendations.

    Abstract Background: Infections are an important cause of morbidity and mortality in T-cell lymphomas. Factors contributing to increased risk of infection include the nature of the underlying disease, as well as treatment-associated immunosuppression. Currently there are few reports describing the types of infections, including preventable infections, in this cohort of patients. The aim of the study was to identify the type, frequency and severity of infection in patients with T-cell lymphoma undergoing treatment.
    Methods: A case series was performed on all patients with T-cell lymphoma over a 5-year period from 2011 to 2016 at a tertiary Australian hospital. Information was collected from medical record review regarding patient demographics, lymphoma treatment and outcomes, and infectious outcomes. Severe infections were recorded, defined as infection requiring hospitalization.
    Results: Sixteen patients were identified with a diagnosis of T-cell lymphoma who received treatment at our institution. There were 42 discrete episodes of severe infections in total. Severe infections occurred in 81% of patients, with over 40% having more than one infection. The median length of hospital stay was 13 days, 33% required intensive care admission and 14% of infectious episodes resulted in death. Only 50% of infectious episodes were microbiologically proven, with the most common etiology being bacterial. The most commonly isolated organism overall was
    Conclusion: Infections are frequent, opportunistic and severe in patients with T-cell lymphoma. Our data suggests that fungal prophylaxis may be indicated with T-cell lymphoma.

    Abstract Despite improvements in graft survival, solid organ transplantation is still associated with considerable infection induced morbidity and mortality. If we were able to show that serious infection risk was associated with excessive suppression of immune capacity, we would be justified in "personalizing" the extent of immunosuppression by carefully monitored reduction to see if we can improve immune compromize without increasing the risk of rejection. Reliable biomarkers are needed to identify this patients at an increased risk of infection. This review focuses on the currently available evidence in solid organ transplant recipients for immune non-pathogen specific biomarkers to predict severe infections with the susceptibility to particular pathogens according to the component of the immune system that is suppressed. This review is categorized into immune biomarkers representative of the humoral, cellular, phagocytic, natural killer cell and complement system. Biomarkers humoral and cellular systems of the that have demonstrated an association with infections include immunoglobulins, lymphocyte number, lymphocyte subsets, intracellular concentrations of adenosine triphosphate in stimulated CD4
