Abstract
Glucocorticoids are widespread anti-inflammatory medications used in medical practice. The immunosuppressive effects of systemic glucocorticoids and increased susceptibility to infections are widely appreciated. However, the dose-dependent model frequently used may not accurately predict the risk of infection in all patients treated with long-term glucocorticoids. In this review, we examine the risks of opportunistic infections (OIs) in patients requiring glucocorticoid therapy by evaluating the influence of the glucocorticoid dose, duration, and potency, combined with biological and host clinical factors and concomitant immunosuppressive therapy. We propose strategies to prevent OIs, which involve screening, antimicrobial prophylaxis, and immunizations. While this review focuses on patients with autoimmune, inflammatory, or neoplastic diseases, the potential risks and preventative strategies are likely applicable to other populations. Clinicians should actively assess the benefit-harm ratios of systemic glucocorticoids and implement preventive efforts to decrease their associated infections complications.

Abstract
Late opportunistic infections (OI) occurring beyond the first year after kidney transplantation (KT) are poorly described and not targeted by prophylactic strategies. We performed a ten-year retrospective monocentric cohort study describing epidemiology, risk factors and impact of late OI occurring 1 year after KT. We included clinically symptomatic OI requiring treatment besides BK virus nephropathy. Control groups included early OI occurring in the first year after KT, and KT recipients without OI since KT and alive with a functional allograft at 1 year. Among 1066 KT recipients, 185 (19.4%) presented a first episode of OI 21.0 (8.0-45.0) months after KT: 120 late OI (64.9%) and 65 early OI (35.1%). Late OI were mainly viral (N = 83, 69.2%), mostly herpes zoster (HZ) (N = 36, 43.4%). Pneumocystis represented most late fungal infections (N = 12/25, 48%). Compared to early OI, we reported more pneumocystis (p = 0.002) and less invasive aspergillosis (p = 0.01) among late OI. Patients with late OI were significatively younger at KT (54.0 ± 13.3 vs. 60.2 ± 14.3 years, p = 0.05). Patient and allograft survival rates between late OI and control groups were similar. Only age was independently associated with mortality. While late OI were not associated with higher mortality or graft loss, implementing prophylactic strategies might prevent such infections.

Abstract
OBJECTIVE To evaluate risk of infections requiring hospitalization and opportunistic infections, including tuberculosis, in patients with rheumatoid arthritis (RA) treated with abatacept versus conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs) and other biologic/targeted synthetic (b/ts) DMARDs. METHODS Five international observational data sources were used: two biologic registries (Sweden, Germany), a disease registry (USA) and two healthcare claims databases (Canada, USA). Crude incidence rates (IRs) per 1000 patient-years, with 95 % CIs, were used to estimate rate ratios (RRs) comparing abatacept versus csDMARDs or other b/tsDMARDs. RRs were adjusted for demographic factors, comorbidities, and other potential confounders and then pooled across data sources using a random effects model (REM). RESULTS The data sources included 6450 abatacept users, 136,636 csDMARD users and 54,378 other b/tsDMARD users, with a mean follow-up range of 2.2-6.2 years. Across data sources, the IRs for infections requiring hospitalization ranged from 16 to 56 for abatacept, 19-46 for csDMARDs, and 18-40 for other b/tsDMARDs. IRs for opportunistic infections were 0.4-7.8, 0.3-4.3, and 0.5-3.8; IRs for tuberculosis were 0.0-8.4, 0.0-6.0, and 0.0-6.3, respectively. The pooled adjusted RR (95 % CI), only reported for infections requiring hospitalization, was 1.2 (0.6-2.2) for abatacept versus csDMARDs and 0.9 (0.6-1.3) versus other b/tsDMARDs. CONCLUSIONS Data from this international, observational study showed similar hospitalized infection risk for abatacept versus csDMARDs or other b/tsDMARDs. IRs for opportunistic infections, including tuberculosis, were low. These data are consistent with the known safety profile of abatacept.

Abstract
Post-transplantation cyclophosphamide (PTCy) is an effective strategy for graft-versus-host disease (GVHD) prophylaxis and is the standard of care for haploidentical hematopoietic cell transplantation (HCT). It is increasingly used for matched and mismatched unrelated donor (MUD/MMUD) HCT, but infections remain a concern. The objective of this study was to evaluate the characteristics and risk factors for infections in haploidentical and unrelated donor HCT recipients treated with PTCy-based GVHD prophylaxis. This single-center retrospective study examined 354 consecutive adults undergoing HCT with PTCy-based GVHD prophylaxis (161 MUD/MMUD; 193 haploidentical) between 2015 and 2022. Opportunistic infections (OIs), including cytomegalovirus (CMV), adenovirus (AdV), Epstein-Barr virus (EBV), and invasive fungal disease (IFD), were assessed from day 0 through day +365. The 1-year cumulative incidence functions of OIs and nonrelapse mortality (NRM) were calculated using dates of relapse and repeat HCT as competing risks. Secondary analysis evaluated risk factors for OIs and NRM using univariate and multivariable Cox regression models. Haploidentical HCT recipients had an increased risk of OIs compared to unrelated donor allograft recipients (39% for haploidentical versus 25% for MUD/MMUD; hazard ratio [HR], 1.70; 95% confidence interval [CI], 1.16 to 2.49; P = .006). On multivariable analysis, haploidentical donor (HR, 1.50; 95% CI, 1.01 to 2.23; P = .046), prior HCT (HR, 1.99; 95% CI, 1.29 to 3.09; P = .002), and diagnosis of aGVHD (HR, 1.47; 95% CI, 1.02 to 2.14; P = .041) were associated with increased risk of OIs. NRM within the first year was not significantly different between the 2 cohorts (HR, 1.11; 95% CI, .64 to 1.93; P = .70). Overall, haploidentical donor was a significant risk factor for OIs in patients receiving PTCy, although 1-year NRM was not different between haploidentical HCT and MUD/MMUD HCT recipients. CMV and AdV infections were significantly increased among haploidentical HCT recipients, whereas the incidences of EBV infection and IFD were similar in the 2 cohorts. Our findings may have implications for infection monitoring and prophylaxis in the setting of PTCy, particularly in haploidentical HCT recipients.

Abstract
OBJECTIVES We compared the incidences of four opportunistic infections (OIs) in patients with rheumatoid arthritis (RA) treated with molecular-targeted drugs from big claims data. MATERIALS AND METHODS We identified 205,906 patients with RA who were prescribed molecular-targeted drugs in 2010-17 from the National Database of Japan and calculated the incidence of four OIs (Pneumocystis pneumonia, tuberculosis, nontuberculous mycobacterial infection, and herpes zoster). RESULTS The total number of Pneumocystis pneumonia, tuberculosis, nontuberculous mycobacterial infection, and herpes zoster patients with biological disease-modifying antirheumatic drugs or tofacitinib treatment history in RA was 765, 1158, 834, and 18,336, respectively. The incidence rates of each OI for all biological disease-modifying antirheumatic drugs were 0.14, 0.14, 0.09, and 2.40 per 100 person-years, respectively, while for tofacitinib they were 0.22, 0.22, 0.07, and 7.00 per 100 person-years. No big difference was observed among biological disease-modifying antirheumatic drugs. All OIs showed higher incidence in those >65 years, but Pneumocystis pneumonia, nontuberculous mycobacterial infection, and herpes zoster showed no difference between those 65-74 years old and those >75 years old. The median of occurrence was the third, seventh, ninth, and thirteenth month after treatment, respectively. CONCLUSIONS We counted real incidence rates of OIs for the whole nation from big claims data.

Abstract
BACKGROUND We report the results of an observational study, analyzing the clinical course of kidney transplant patients hospitalized for COVID-19 and comparing it with a control to determine if outcomes, nosocomial, and opportunistic infections were different between groups. METHODS An observational, retrospective, case-control, single-center study, including a group of kidney transplant adults diagnosed with COVID-19, from March 2020 to April 2022. Transplant patients hospitalized for COVID-19 comprised the cases. The control group consisted of non-transplanted adults, without immunosuppressive treatment, hospitalized for COVID-19, and matched by age, sex, and month at diagnosis of COVID-19. Study variables were collected, including demographic/clinical, epidemiologic, clinical/biological at diagnosis, evolutive, and outcome variables. RESULTS Fifty-eight kidney transplant recipients were included. Thirty required hospital admission. Ninety controls were included. Transplant recipients had a higher frequency of intensive care unit (ICU) admission, ventilatory support, and death. The relative risk for death was 2.45. When adjusted by baseline estimated glomerular filtration rate (eGFR) and comorbidity, only the risk for opportunistic infection remained high. Variables independently associated with death were dyslipidemia, eGFR at admission, MULBSTA score, and ventilatory support. Pneumonia by Klebsiella oxytoca was the most frequent nosocomial infection. Pulmonary aspergillosis was the most frequent opportunistic infection overall. Pneumocystosis and cytomegalovirus colitis were more frequent among transplant patients. The relative risk for opportunistic infection in this group was 1.88. Baseline eGFR, serum interleukin 6 level, and coinfection were independently associated with it. CONCLUSIONS Evolutive course of COVID-19 requiring hospitalization in renal transplant recipients was primarily determined by comorbidity and baseline kidney function. At equal comorbidity and renal function, there were no differences in mortality, ICU admission, nosocomial infection, and hospital stay. However, the risk for opportunistic infection remained high.

Abstract
BACKGROUND The Inflammatory Bowel Disease (IBD) patients have adopted lifestyle modifications to prevent infection via SARS COV-2. AIMS This study aims to examine rate of serious infections and opportunistic infections in the pre-pandemic and pandemic period, and to analyse if the risk associated with medications used to treat IBD were potentially modified by associated change in lifestyle. METHODS We conducted a retrospective cohort study of patients from the US national Veteran Affairs Healthcare System (VAHS). Patients were stratified into two groups: pre-pandemic (prior to SARS COV-2 pandemic) and pandemic (during SARS COV-2 pandemic) and outcomes were measured in these groups. Primary outcome was occurrence of any serious infection. Secondary outcome was occurrence of any opportunistic infection. RESULTS There were 17,202 IBD patients in the pre-pandemic era and 15,903 patients in the pandemic era. The pre-pandemic era had a significantly higher proportion of serious infections relative to the pandemic era (5.1% vs. 4.4%, p = 0.002). The proportion of opportunistic infections were similar between pre-pandemic and pandemic eras (0.3% vs. 0.3%, p = 0.82). Relative to 5-ASA, patients taking anti-TNF (HR = 1.50 (1.31-1.72)), anti-TNF+TP (HR = 1.56 (1.24-1.95)) or vedolizumab (HR = 1.81 (1.49-2.20)) had an increased hazard of serious infection (p > 0.001). CONCLUSION In a nationwide cohort of IBD patients, we found that risk of serious infections could possibly be affected by behavioural modifications due to SARS-COV-2 pandemic.

Abstract
BACKGROUND AND AIMS Advanced therapies for inflammatory bowel disease [IBD] could potentially lead to a state of immunosuppression with an increased risk of opportunistic infections [OIs]. We aimed to provide an update on the incidence of OIs among adult IBD patients in randomized controlled trials [RCTs] of approved biologics and small-molecule drugs [SMDs]. Also, we aimed to describe OI definitions utilized in RCTs, to ultimately propose a standardized definition. METHODS Electronic databases were searched from January 1, 1990, until April 16, 2022. Our primary outcome was incidence rate of overall OIs among IBD patients exposed and unexposed to biologics or SMDs. We also describe specific OIs reported in included trials, as well as definitions of OIs within studies when provided. RESULTS Ninety studies were included. The incidence rates of reported OIs were 0.42 and 0.21 per 100 person-years in patients exposed to advanced therapies and placebo, respectively. This was highest for anti-tumour necrosis factors [0.83 per 100 person-years] and Janus kinase inhibitors [0.55 per 100 person-years] and lowest for anti-integrins and ozanimod. On meta-analysis, no increased risk of OIs was observed. None of the studies provided a detailed definition of OIs, or a comprehensive list of infections considered as OIs. CONCLUSION Different mechanisms of action may have specific OI profiles. In the absence of a uniform definition of OIs, these estimates are less reliable. We propose a definition to be used in future studies to help provide standardized reporting. When using this definition, we saw significant differences in incidence rates of OIs across mechanisms of action.

Abstract
Introduction: Opportunistic infections (OIs) are the leading cause of morbidity and mortality among adults living with HIV. Current and accurate information about the occurrence of opportunistic infections in HIV-infected adults is critical for developing more effective treatments and interventions. However, few studies have been conducted in Ethiopia on the prevalence of common opportunistic infections in HIV-infected adults. Thus, the purpose of this study was to determine the prevalence and predictors of opportunistic infections among HIV-infected adults receiving antiretroviral therapy (ART) at the comprehensive specialized hospital affiliated with the University of Gondar.Methods: Between January 11, 2015, and January 10, 2021, a retrospective cohort study was conducted at the University of Gondar comprehensive specialized hospital. A total of 715 HIV-infected adults on ART were included in the study. Data were extracted from the charts of HIV-infected adults using a data extraction form adapted from the ART entry and follow-up forms. Epi-dataTM Version 4.5 was used to enter data, and StataTM Version 16 was used to analyze the data. The time interval between opportunistic infections was estimated using the Kaplan Meier survival curve. To identify risk predictors of opportunistic infections, bivariate and multivariate semi-parametric and parametric regression models were fitted.Result: This study included the records of 715 HIV-infected adults-initiated ART between January 11, 2015, to January 10, 2021. During the follow-up period, the overall incidence of opportunistic infections was 4.1 (95 percent CI 3.74 to 4.44) per 10,000 person-year observation, with a median of 57 months (IQR = 40-69 months). Pneumocystis' pneumonia at 90(16.51%) was the most encountered OI at follow-up. Adults are presenting with baseline CD4 < 200 cells/µl counts (AHR = 1.41, 95% CI 1.18 to 1.69), bedridden baseline functional status (AHR = 1.35, 95% CI 1.01 to 1.82), WHO clinical stage II (AHR = 5.87, 95% CI 3.97 to 8.69) and WHO clinical stage III (AHR = 5.85, 95% CI 3.55 to 9.65) were notably associated with the incidence of opportunistic infections development.Conclusions: Opportunistic infections are uncommon among HIV-infected adults in this study. In terms of predictors, such as a low CD4 count and an advanced WHO stage (II or III), bedridden functional status was found to be significantly associated with OIs.

Abstract
Opioids are excellent analgesics for the clinical treatment of various types of acute and chronic pain, particularly cancer-related pain. Nevertheless, it is well known that opioids have some nasty side effects, including immunosuppression, which is commonly overlooked. As a result, the incidence of opportunistic bacterial and viral infections increases in patients with long-term opioid use. Nowadays, there are no effective medications to alleviate opioid-induced immunosuppression. Understanding the underlying molecular mechanism of opioids in immunosuppression can enable researchers to devise effective therapeutic interventions. This review comprehensively summarized the exogenous opioids-induced immunosuppressive effects and their underlying mechanisms, the regulatory roles of endogenous opioids on the immune system, the potential link between opioid immunosuppressive effect and the function of the central nervous system (CNS), and the future perspectives in this field.

Abstract
OBJECTIVES The aim of this study was to describe the incidence, clinical characteristics, and risk factors of late-onset opportunistic infections (LOI) in people who live with HIV (PWLHA) within the Caribbean, Central and South America network for HIV epidemiology. METHODS We performed a retrospective cohort study including treatment-naive PWLHA enrolled at seven sites (Argentina, Brazil, Chile, Peru, Mexico, and two sites in Honduras). Follow-up began at 6 months after treatment started. Outcomes were LOI, loss to follow-up, and death. We used a Cox proportional hazards model and a competing risks model to evaluate risk factors. RESULTS A total of 10,583 patients were included. Median follow up was at 5.4 years. LOI occurred in 895 (8.4%) patients. Median time to opportunistic infection was 2.1 years. The most common infections were tuberculosis (39%), esophageal candidiasis (10%), and Pneumocystis jirovecii (P. jirovecii) pneumonia (10%). Death occurred in 576 (5.4%) patients, and 3021 (28.5%) patients were lost to follow-up. A protease inhibitor-based regimen (hazard ratio 1.25), AIDS-defining events during the first 6 months of antiretroviral-treatment (hazard ratio 2.12), starting antiretroviral-treatment in earlier years (hazard ratio 1.52 for 2005 vs 2010), and treatment switch (hazard ratio 1.31) were associated with a higher risk of LOI. CONCLUSION LOI occurred in nearly one in 10 patients. People with risk factors could benefit from closer follow-up.

Abstract
Over the past decades, the advent of targeted and biological therapies has revolutionized the management of cancer and autoimmune, hematological and inflammatory conditions. Although a large amount of information is now available on the risk of opportunistic infections associated with some of these agents, the evidence regarding the susceptibility to bacterial infections is more limited. Biological agents have been shown to entail a variable risk of bacterial infections in pivotal randomized clinical trials and post-marketing studies. Recommendations on risk minimization strategies and therapeutic interventions are therefore scarce and often based on expert opinion, with only a few clear statements for some particular agents (i.e. meningococcal vaccination for patients receiving eculizumab). In the present review the available information regarding the incidence of and risk factors for bacterial infection associated with the use of different groups of biological agents is summarized according to their mechanisms of action, and recommendations based on this evidence are provided. Additional information coming from clinical research and real-world studies is required to address unmet questions in this emerging field.

Abstract
Background In the era of the COVID-19 pandemic, people living with HIV (PLWH) face more challenges. However, it is unclear if PLWH is more susceptible to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than HIV-negative individuals. This study aimed to explore the prevalence of the SARS-CoV-2 infection and the associated risk factors among PLWH. Methods From 1 to 30 May 2020, we conducted a cross-sectional survey that enrolled 857 PLWH and 1,048 HIV-negative individuals from the Wuchang district in Wuhan, China. Our data analysis compared the rate of the SARS-CoV-2 infection among PLWH and HIV-negative participants, and the proportions of symptomatic patients and asymptomatic infectors between the two groups. We also assessed the risk factors associated with the SARS-CoV-2 infection among PLWH. Results Overall, 14/857 (1.6%) PLWH and 68/1,048 (6.5%) HIV-negative participants were infected with SARS-CoV-2. Among the SARS-CoV-2-infected PLWH participants, 6/14 (42.8%) were symptomatic patients, 4/14 (28.6%) were SARS-CoV-2 nucleic acid-positive asymptomatic infectors, and 4/14 (28.6%) were serology-positive asymptomatic infectors. Among the infected HIV-negative participants, 5/68 (7.4%) patients were symptomatic and 63/68 (92.6%) were serology-positive asymptomatic infectors. The rate of the SARS-CoV-2 infection was lower among the PLWH than in the HIV-negative group (1.96% vs. 5.74%, p = 0.001) and the rate of morbidity among the symptomatic patients was similar between the two groups (p = 0.107). However, there were more serology-positive asymptomatic infectors among the infected HIV-negative participants than among the infected PLWH (0.54% vs. 5.46%, p = 0.001). Furthermore, being 50 years or older (aOR = 4.50, 95% CI: 1.34-15.13, p = 0.015) and having opportunistic infections (aOR = 9.59, 95% CI: 1.54-59.92, p = 0.016) were associated with an increased risk of SARS-CoV-2 infection among PLWH. Conclusions PLWH has more varied forms of the SARS-CoV-2 infection than the HIV-negative population and should, therefore, undertake routine screening to avoid late diagnosis. Also, older age (≥50 years) and having opportunistic infections increase the risks of SARS-CoV-2 infection among PLWH.

Abstract
After cardiovascular diseases, infectious diseases are the second most common cause of death worldwide. Although these infections are caused mainly by viruses or bacteria, a systematically growing prevalence of human and animal opportunistic fungal infections is noticeable worldwide. More attention is being paid to this problem, especially due to the growing frequency of recalcitrant and recurrent mycoses. The latter are classically divided into superficial, which are the most common type, subcutaneous, and systemic. This work discusses opportunistic fungal pathogens without proven horizontal transmission between different animal species including humans and microsporidia as spore-forming unicellular parasites related to fungi; however, with a yet undetermined taxonomic position. The review also mentions aetiological agents, risk factors, epidemiology, geographical distribution, and finally symptoms characteristic for individual disease entities. This paper provides insight into fungal infections from a global perspective and simultaneously draws attention to emerging pathogens, whose prevalence is continuously increasing. Finally, this work also takes into consideration the correct nomenclature of fungal disease entities and the importance of secondary metabolites in the pathogenesis of fungal infections.

Abstract
Secondary immunodeficiency is reported in most patients with hematological malignancies such as chronic lymphocytic leukemia and multiple myeloma. The aim of our review was to evaluate the existing literature data on patients with hematological malignancies, with regard to the effect of immunodeficiency on the outcome, the clinical and therapeutic approach, and on the onset of noninfectious complications, including thrombosis, pleural effusion, and orofacial complications. Immunodeficiency in these patients has an intense impact on their risk of infection, in turn increasing morbidity and mortality even years after treatment completion. However, these patients with increased risk of severe infectious diseases could be treated with adequate vaccination coverage, but the vaccines' administration can be associated with a decreased immune response and an augmented risk of adverse reactions. Probably, immunogenicity of the inactivated is analogous to that of healthy subjects at the moment of vaccination, but it undertakes a gradual weakening over time. However, the dispensation of live attenuated viral vaccines is controversial because of the risk of the activation of vaccine viruses. A particular immunization schedule should be employed according to the clinical and immunological condition of each of these patients to guarantee a constant immune response without any risks to the patients' health.

Abstract
OBJECTIVE To determine the incidence rate, predictors and outcome of severe infections in a population-based cohort of ANCA-associated vasculitis (AAV). METHODS The study included 325 cases of AAV (152 female) diagnosed from 1997 through 2016 from a defined geographic area in Sweden. All severe infection events (requiring hospitalization and treatment with intravenous antimicrobials) were identified. The Birmingham vasculitis activity score (BVAS) was used to evaluate disease activity, and organ damage was assessed using the vasculitis damage index (VDI). Patients were followed from time of AAV diagnosis to death or December 2017. RESULTS A total of 129 (40%) patients suffered at least one severe infection. In 2307 person-years (PY) of follow-up, 210 severe infections were diagnosed. The incidence rate of severe infections was 9.1/100 PY and was highest during the first year following AAV diagnosis at 22.1/100 PY (P < 0.001). Pneumonia, sepsis and urinary tract infection were the most common infections. Opportunistic infections constituted only 6% of all severe infections. In Cox regression analysis age and BVAS at diagnosis were the only factors independently predicting severe infection [hazard ratio: 1.54 (P < 0.001) and 1.27 (P = 0.001), respectively]. Severe infection was associated with poorer prognosis with respect to median VDI score 12 months post-AAV diagnosis, renal survival and mortality. Severe infections were the cause of death in 32 patients (22% of all deaths). CONCLUSION . Severe infection is a common problem in AAV, with the most important prognostic factors being older age and high disease activity at diagnosis. Severe infections are associated with permanent organ damage and high mortality.

Abstract
Over the past decades, the treatment of inflammatory bowel diseases (IBD) has become more targeted, anticipating the use of immune-modifying therapies at an earlier stage. This top-down approach has been correlated with favorable short and long-term outcomes, but it has also brought with it concerns regarding potential infectious complications. This large IBD population treated with immune-modifying therapies, especially if combined, has an increased risk of severe infections, including opportunistic infections that are sustained by viral, bacterial, parasitic, and fungal agents. Viral infections have emerged as a focal safety concern in patients with IBD, representing a challenge for the clinician: they are often difficult to diagnose and are associated with significant morbidity and mortality. The first step is to improve effective preventive strategies, such as applying vaccination protocols, adopt adequate prophylaxis and educate patients about potential risk factors. Since viral infections in immunosuppressed patients may present atypical signs and symptoms, the challenges for the gastroenterologist are to suspect, recognize and diagnose such complications. Appropriate treatment of common viral infections allows us to minimize their impact on disease outcomes and patients’ lives. This practical review supports this standard of care to improve knowledge in this subject area.

Abstract
BACKGROUND AND AIMS Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis. We report integrated analyses of infections in the Phase [P]2 and P3 OCTAVE programmes. METHODS Three cohorts were analysed: Induction [P2/3 induction studies]; Maintenance [P3 maintenance study]; and Overall [all tofacitinib-treated patients in induction, maintenance, or ongoing, open-label, long-term extension studies; as of May 2019]. Proportions and incidence rates [IRs; unique patients with events/100 patient-years] of serious infections [SIs], herpes zoster [HZ] [non-serious and serious], and opportunistic infections [OIs] are reported [censored at time of event]. RESULTS In the Induction Cohort [N = 1220], no patients receiving placebo and eight [0.9%] receiving tofacitinib 10 mg twice daily [BID] developed SIs. Maintenance Cohort [N = 592] SI IRs (95% confidence interval [CI]) were 1.94 [0.23-7.00] for placebo and 1.35 [0.16-4.87] and 0.64 [0.02-3.54] for tofacitinib 5 and 10 mg BID, respectively; HZ IRs were 0.97 [0.02-5.42], 2.05 [0.42-6.00], and 6.64 [3.19-12.22], respectively. In the Overall Cohort [N = 1157; 82.9% predominantly received tofacitinib 10 mg BID], SI, HZ, and non-HZ OI IRs were 1.70 [1.24-2.27], 3.48 [2.79-4.30], and 0.15 [0.04-0.38], respectively. No SIs resulted in death. CONCLUSIONS During induction, SIs were more frequent with tofacitinib versus placebo. SIs were generally infrequent in the Maintenance and Overall Cohorts, with rates comparable between treatment groups. Maintenance Cohort HZ IR was numerically higher with tofacitinib 10 mg BID versus 5 mg BID. Overall Cohort HZ IRs remained stable over time. Non-HZ OIs and viral infections were rare.

Abstract
OBJECTIVES Predicting serious infections (SI) in patients with rheumatoid arthritis (RA) is crucial for the implementation of appropriate preventive measures. Here we aimed to identify risk factors for SI and to validate the RA Observation of Biologic Therapy (RABBIT) risk score in real-life settings. METHODS A multi-centre, prospective, RA cohort study in Greece. Demographics, disease characteristics, treatments and comorbidities were documented at first evaluation and one year later. The incidence of SI was recorded and compared with the expected SI rate using the RABBIT risk score. RESULTS A total of 1557 RA patients were included. During follow-up, 38 SI were recorded [incidence rate ratio (IRR): 2.3/100 patient-years]. Patients who developed SI had longer disease duration, higher HAQ at first evaluation and were more likely to have a history of previous SI, chronic lung disease, cardiovascular disease and chronic kidney disease. By multivariate analysis, longer disease duration (IRR: 1.05; 95% CI: 1.005, 1.1), history of previous SI (IRR: 4.15; 95% CI: 1.7, 10.1), diabetes (IRR: 2.55; 95% CI: 1.06, 6.14), chronic lung disease (IRR: 3.14; 95% CI: 1.35, 7.27) and daily prednisolone dose ≥10 mg (IRR: 4.77; 95% CI: 1.47, 15.5) were independent risk factors for SI. Using the RABBIT risk score in 1359 patients, the expected SI incidence rate was 1.71/100 patient-years, not different from the observed (1.91/100 patient-years; P = 0.97). CONCLUSION In this large real-life, prospective study of RA patients, the incidence of SI was 2.3/100 patient-years. Longer disease duration, history of previous SI, comorbidities and high glucocorticoid dose were independently associated with SI. The RABBIT score accurately predicted SI in our cohort.

Abstract
BACKGROUND Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection in immunocompromised patients. Clusters of PJP, especially among organ transplant recipients in clinic settings were described. Data regarding nosocomial PJP infection among inpatients are limited. OBJECTIVES To assess the magnitude and characteristics of inpatient healthcare-associated PJP infection (HCA-PJP) in HIV-negative patients. METHODS A retrospective chart review of hospitalized PJP patients was performed to identify HCA-PJP. The study was performed at six medical centers in Israel from 2006 to 2016. HCA-PJP was defined as cases of hospital-onset or those with documented contact with a PJP patient. We reviewed and cross-matched temporal and spatial co-locations of patients. Clinical laboratory characteristics and outcomes were compared. RESULTS Seventy-six cases of PJP were identified. Median age was 63.7 years; 64% men; 44% hematological malignancies; 18% inflammatory diseases; and 61% steroid usage. Thirty-two patients (42%) were defined as HCA-PJP: 18/32 (23.6%) were hospitalized at onset and 14/32 (18.4%) had a previous encounter with a PJP patient. Time from onset of symptoms to diagnosis was shorter in HCA-PJP vs. community-PJP (3.25 vs. 11.23 days, P = 0.009). In multivariate analysis, dyspnea at presentation (odds ratio [OR] 16.79, 95% confidence interval [95%CI] 1.78-157.95) and a tendency toward higher rate of ventilator support (72% vs. 52%, P = 0.07, OR 5.18, 95%CI 0.7-30.3) were independently associated with HCA-PJP, implying abrupt disease progression in HCA-PJP. CONCLUSIONS HCA-PJP was common. A high level of suspicion for PJP among selected patients with nosocomial respiratory infection is warranted. Isolation of PJP patients should be considered.

Abstract
Autopsy continues to play an essential role in monitoring opportunistic fungal infections. However, few studies have analysed the historical trends of fungal infections in autopsies. Here, we analyse available data on fungal infections obtained from autopsy reports during 85 years of autopsies performed by the largest autopsy service in Brazil. All invasive fungal infections presented in autopsy reports between 1930 and 2015 were included. Of the 158,404 autopsy reports analysed, 1096 involved invasive fungal infections. In general, paracoccidioidomycosis (24%) was the most frequent infection, followed by candidiasis (18%), pneumocystosis (11.7%), cryptococcosis (11%), aspergillosis (11%) and histoplasmosis (3.8%). Paracoccidioidomycosis decreased after the 1950s, whereas opportunistic fungal infections increased steadily after the 1980s during the peak of the AIDS pandemic. The lung was the most frequently affected organ (73%). Disseminated infection was present in 64.5% of cases. In 26% of the 513 cases for which clinical charts were available for review, the diagnosis of opportunistic fungal infections was performed only at autopsy. Our unique 85-year history of autopsies showed a transition from endemic to opportunistic fungal infections in São Paulo, Brazil, reflecting increased urbanization, the appearance of novel diseases, such as AIDS in the 1980s, and advances in medical care over time.

Abstract
Fungal co-infections, especially with Aspergillus and Candida species, are prevalent in hospitalised COVID-19 patients, and could influence patient outcomes and hamper treatment efforts. However, information about and elucidation of the causal relationship between fungal co-infections and COVID-19 disease outcomes or severity in patients are still lacking. Such information, if and when available, will help facilitate appropriate case management.

Abstract
The epidemiology of lymphomas has changed since the use of antiretroviral therapy. The incidence of Non-Hodgkin Lymphomas (NHL) has significantly decreased in high income countries but not in low and middle-income countries where AIDS-related events remain high. This observational study describes the characteristics, infectious complications and main outcomes of patients diagnosed with HIV and lymphoma at the Instituto Nacional de Cancerología.All adults >18 years diagnosed with HIV and lymphoma from January 2010 to December 2017 were included. Information on HIV and lymphoma was collected, as well as the occurrence of co-infections at diagnosis and during therapy. Multiple regression was done with NHL patients to evaluate independent variables associated to death.One hundred fifty three patients were included: 127 patients with NHL (83%) and 26 (17%) with Hodgkin lymphoma (HL). Of the NHL, 49 (38%) were diffuse large B cell Lymphomas (DLBCL), 35 (27%) plasmablastic, 28 (23%) Burkitt, 10 (8%) primary DLBCL of Central Nervous system, 3 (2%) T-cell lymphomas, and 2 (2%) pleural effusion lymphoma. Most patients were diagnosed in an advanced stage: 70% of NHL had a high International Prognostic Index (IPI); 68% of patients had <200 cells/mm. Almost 25% of NHL patients had an opportunistic infection at lymphoma diagnosis. During chemotherapy, 60% of all patients presented with at least 1 serious non-opportunistic infectious complication, and 50% presented 2 or more infectious complications, mostly bacterial infections. Thirty six percent of NHL and 23% of HL died. After adjusting for confounders, the variables associated with death were IPI and lymphoma type.HIV positive patients with lymphoma in our institution are diagnosed with an advanced stage and a high burden of infections complications. Death remains high and the variables strongly associated with death are those related to lymphoma prognosis such as lymphoma type and IPI.

Abstract
OBJECTIVE To investigate the incidence, clinical features, and risk factors of opportunistic infections in elderly patients with inflammatory bowel disease (IBD). STUDY DESIGN Observational study. PLACE AND DURATION OF STUDY Department of Digestive and Geriatrics Center, Sichuan University West China Hospital, China between January 2012 and January 2019. METHODOLOGY Patients (≥18 years) with IBD were enrolled in this study. Clinical data from the infected elderly group (age ≥60 years), non-infected elderly group (age ≥60 years) and infected adult group (age: 18-59 years) were compared. Logistic regression analysis was used for risk factors associated with opportunistic infection. RESULTS A total of 8.9% (307/3,456) of patients with IBD had opportunistic infection. The opportunistic infection rate of elderly group was 16.5% (80/485), which was significantly higher than that of adult group (7.6%, 227/2,971, p <0.05). Compared with infected adult group or non-infected elderly group, infected elderly group had less fever and leukocytosis, but more hypoproteinemia and several activities (p <0.05). Cytomegalovirus and Epstein-Barr virus were the most common agents in elderly group and adult group, respectively. Multiple episodes (three or more) were more common in infected elderly group; the time of opportunistic infections was associated with systemic inflammatory reaction syndrome (SIRS, p <0.05). Logistic regression analysis showed that age ≥60 years, corticosteroids, immunosuppressive and biological agents were risk factors for opportunistic infections in patients with IBD. CONCLUSION Hospitalised elderly IBD patients, receiving corticosteroids, immunosuppressive, and biological agents, are at higher risk for infection. The symptoms of opportunistic infections in elderly patients are atypical, but they are prone to multiple infections with poor prognosis. Key Words: Elderly patients, Inflammatory bowel disease, Opportunistic infection, Systemic inflammation reaction syndrome.

Abstract
Aims Heart transplantation may represent a particular risk factor for severe coronavirus infectious disease 2019 (COVID-19) due to chronic immunosuppression and frequent comorbidities. We conducted a nation-wide survey of all heart transplant centers in Germany presenting the clinical characteristics of heart transplant recipients with COVID-19 during the first months of the pandemic in Germany. Methods and results A multicenter survey of all heart transplant centers in Germany evaluating the current status of COVID-19 among adult heart transplant recipients was performed. A total of 21 heart transplant patients with COVID-19 was reported to the transplant centers during the first months of the pandemic in Germany. Mean patient age was 58.6 ± 12.3 years and 81.0% were male. Comorbidities included arterial hypertension (71.4%), dyslipidemia (71.4%), diabetes mellitus (33.3%), chronic kidney failure requiring dialysis (28.6%) and chronic-obstructive lung disease/asthma (19.0%). Most patients received an immunosuppressive drug regimen consisting of a calcineurin inhibitor (71.4%), mycophenolate mofetil (85.7%) and steroids (71.4%). Eight of 21 patients (38.1%) displayed a severe course needing invasive mechanical ventilation. Those patients showed a high mortality (87.5%) which was associated with right ventricular dysfunction (62.5% vs. 7.7%; p = 0.014), arrhythmias (50.0% vs. none; p = 0.012), and thromboembolic events (50.0% vs. none; p = 0.012). Elevated high-sensitivity cardiac troponin T- and N-terminal prohormone of brain natriuretic peptide were significantly associated with the severe form of COVID-19 (p = 0.017 and p < 0.001, respectively). Conclusion Severe course of COVID-19 was frequent in heart transplanted patients. High mortality was associated with right ventricular dysfunction, arrhythmias, thromboembolic events, and markedly elevated cardiac biomarkers.

Abstract
Autoimmune and autoinflammatory diseases are associated with severe morbidity, and represent an impactful health and economic burden worldwide. The treatment of these diseases can include a course with detrimental side effects. Immunosuppression increases the risk of opportunistic infections, but in some cases, the abrupt discontinuation of these medications can result in immune reconstitution inflammatory syndrome. Special attention must be directed to endemic tropical infections, such as leishmaniasis, Chagas disease, malaria, arbovirosis, yellow fever, leprosy, paracoccidioidomycosis, disseminated strongyloidiasis, and ectoparasitosis. These endemic diseases of developing countries can be considered as possible emerging diseases in developed regions partially because of environmental factors and migration. In the present article, we aim to review the evidence-based aspects of the most important opportunistic tropical infections in immunosuppressed patients. We also aim to review the important aspects of vaccination, chemical prophylaxis, and treatment for these infections in people with medication-induced immunosuppression.

Abstract
At the 2020 Conference on Retroviruses and Opportunistic Infections, held virtually as a result of the emerging COVID-19 pandemic, trends in the HIV epidemic were highlighted, with decreasing HIV incidence reported across several countries, although key regions remain heavily impacted, including the US South. Adolescent girls and young women, men who have sex with men (MSM), transgender persons, and people who inject drugs continue to experience a high burden of new infections. Sexually transmitted infections during pregnancy can lead to a number of adverse outcomes in infants; novel strategies to detect and treat these infections are needed. Innovative HIV testing strategies, including self-testing and assisted partner services, are expanding the reach of testing; however, linkage to care can be improved. Novel preexposure prophylaxis (PrEP) delivery strategies are increasing uptake of PrEP in different groups, although adherence and persistence remain a challenge. Use of on-demand PrEP is increasing among MSM in the US. Strategies are needed to address barriers to PrEP uptake and persistence among cis- and transgender women. Several novel regimens for postexposure prophylaxis show promise.

Abstract
BACKGROUND AND PURPOSE The clinical benefit of pre-hematopoietic cell transplantation sinus CT screening remains uncertain, while the risks of CT radiation and anesthesia are increasingly evident. We sought to re-assess the impact of screening sinus CT on pretransplantation patient management and prediction of posttransplantation invasive fungal rhinosinusitis. MATERIALS AND METHODS Pretransplantation noncontrast screening sinus CTs for 100 consecutive patients (mean age, 11.9 ± 5.5 years) were graded for mucosal thickening (Lund-Mackay score) and for signs of noninvasive or invasive fungal rhinosinusitis (sinus calcification, hyperattenuation, bone destruction, extrasinus inflammation, and nasal mucosal ulceration). Posttransplantation sinus CTs performed for sinus-related symptoms were similarly graded. Associations of Lund-Mackay scores, clinical assessments, changes in pretransplantation clinical management (additional antibiotic or fungal therapy, sinonasal surgery, delayed transplantation), and subsequent development of sinus-related symptoms or invasive fungal rhinosinusitis were tested (exact Wilcoxon rank sums, Fisher exact test, significance P < .05). RESULTS Mean pretransplantation screening Lund-Mackay scores (n = 100) were greater in patients with clinical symptoms (8.07 ± 6.00 versus 2.48 ± 3.51, P < .001) but were not associated with pretransplantation management changes and did not predict posttransplantation sinus symptoms (n = 21, P = .47) or invasive fungal rhinosinusitis symptoms (n = 2, P = .59). CONCLUSIONS Pre-hematopoietic cell transplantation sinus CT does not meaningfully contribute to pretransplantation patient management or prediction of posttransplantation sinus disease, including invasive fungal rhinosinusitis, in children. The risks associated with CT radiation and possible anesthesia are not warranted in this setting.

Abstract
The incidence and number of deaths from non-tuberculous mycobacterial (NTM) disease have been steadily increasing globally. These lesser known “cousins” of Mycobacterium tuberculosis (TB) were once thought to be harmless environmental saprophytics and only dangerous to individuals with defective lung structure or the immunosuppressed. However, NTM are now commonly infecting seemingly immune competent children and adults at increasing rates through pulmonary infection. This is of concern as the pathology of NTM is difficult to treat. Indeed, NTM have become extremely antibiotic resistant, and now have been found to be internationally dispersed through person-to-person contact. The reasons behind this NTM increase are only beginning to be elucidated. Solutions to the problem are needed given NTM disease is more common in the tropics. Importantly, 40% of the world's population live in the tropics and due to climate change, the Tropics are expanding which will increase NTM infection regions. This review catalogs the global and economic disease burden, at risk populations, treatment options, host-bacterial interaction, immune dynamics, recent developments and research priorities for NTM disease.

Abstract
Intestinal microsporidiosis is known as an opportunistic infection in immunocompromised patients. The current study aimed to investigate intestinal microsporidia infection in human subjects with/without immunodeficiency. Totally, 600 stool samples were collected from immunocompromised (254) and immunocompetent (346) subjects. DNA extraction was performed and the SSU rRNA and the ITS genes were amplified to detect and characterize microsporidia and the relevant genotypes. Phylogenetic trees were drawn using MEGA7 software to illustrate the correlation between isolates. From 600 enrolled subjects, 283 and 317 were male and female, respectively. The average age ± SD of all tested subjects was 28.85 ± 26.92. The results of PCR demonstrated the presence of E. bieneusi and Encephalitozoon sp., among 10/600 (1.67%) and 26/600 (4.33%) of samples, respectively. Accordingly, E. bieneusi was seen among 4/346 (1.15%), 1/53 (1.88%), 3/124 (2.42%), and 2/63 (3.17%), and Encephalitozoon sp., was detected from 17/346 (4.91%), 3/53 (5.36%), 4/124 (3.22%) and 2/63 (3.17%) of healthy subjects, RA patients, cancer patients, and transplantation recipients, respectively. Statistical significant correlation was not seen between the presence of microsporidia and age, gender, stool appearance, and geographical region. Molecular analysis showed that all E. bieneusi were the genotype D. Phylogenetic tree demonstrated no classification according to the presence/absence of immunodeficiency, geographical locations and presence of diarrhea. The high prevalence of Encephalitozoon sp., in comparison to E. bieneusi in this study suggested the importance of this genus alongside with E. bieneusi in Iran. In addition, predominance of the genotype D highlighted the wide distribution of this genotype in Iran.

Abstract
Fungi are an important but frequently overlooked cause of morbidity and mortality in humans. Life-threatening fungal infections mainly occur in immunocompromised patients, and are typically caused by environmental opportunists that take advantage of a weakened immune system. The filamentous fungus Aspergillus fumigatus is the most important and well-documented mold pathogen of humans, causing a number of complex respiratory diseases, including invasive pulmonary aspergillosis, an often fatal disease in patients with acute leukemia or in immunosuppressed bone marrow or solid organ transplant recipients. However, non-Aspergillus molds are increasingly reported as agents of disseminated diseases, with Fusarium, Scedosporium, Lomentospora and mucormycete species now firmly established as pathogens of immunosuppressed and immunocompetent individuals. Despite well-documented risk factors for invasive fungal diseases, and increased awareness of the risk factors for life-threatening infections, the number of deaths attributable to molds is likely to be severely underestimated driven, to a large extent, by the lack of readily accessible, cheap, and accurate tests that allow detection and differentiation of infecting species. Early diagnosis is critical to patient survival but, unlike Aspergillus diseases, where a number of CE-marked or FDA-approved biomarker tests are now available for clinical diagnosis, similar tests for fusariosis, scedosporiosis and mucormycosis remain experimental, with detection reliant on insensitive and slow culture of pathogens from invasive bronchoalveolar lavage fluid, tissue biopsy, or from blood. This review examines the ecology, epidemiology, and contemporary methods of detection of these mold pathogens, and the obstacles to diagnostic test development and translation of novel biomarkers to the clinical setting.

Abstract
IMPORTANCE The safety profile of interleukin (IL) inhibitors is not well established. OBJECTIVE To assess the risk of serious infections, opportunistic infections, and cancer in patients with rheumatologic diseases treated with IL inhibitors. DATA SOURCES Ovid MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations; Ovid MEDLINE Daily; Ovid Embase; Ovid Cochrane Central Register of Controlled Trials; Ovid Cochrane Database of Systematic Reviews; and Scopus were searched (inception to November 30, 2018). STUDY SELECTION Randomized, placebo-controlled trials that evaluated IL inhibitor therapies in rheumatic diseases and reported safety data were included in the analyses. DATA EXTRACTION AND SYNTHESIS This systematic review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Two investigators independently extracted study data and assessed risk of bias and certainty in the evidence. Fixed-effects meta-analysis was conducted to pool odds ratios (ORs) for serious infections, opportunistic infections, and cancers for IL inhibitors vs placebo. MAIN OUTCOMES AND MEASURES The outcomes of interest were the number of serious infections, opportunistic infections, and cancers in individuals receiving IL inhibitor therapies compared with placebo. RESULTS In this meta-analysis, 74 studies comprising 29 214 patients (24 236 patients for serious infections, 9998 for opportunistic infections, and 21 065 for cancer [number of patients overlaps for each outcome]) were included. Patients receiving IL inhibitors had a higher risk of serious infections (OR, 1.97; 95% CI, 1.58-2.44; P < .001, I2 = 0%; high certainty), opportunistic infections (OR, 2.35; 95% CI, 1.09-5.05; P = .03, I2 = 0%; moderate certainty), and cancer (OR, 1.52; 95% CI, 1.05-2.19; P = .03, I2 = 11%; moderate certainty). CONCLUSIONS AND RELEVANCE The risk of serious infections, opportunistic infections, and cancer appears to be increased in patients with rheumatologic diseases who are treated with IL inhibitors compared with placebo.

Abstract
Infections in immunocompromised-neoplastic patients represent a severe complication. Among bacteria, Enterococcus species constitute a common causative pathogen of urinary tract infections (UTIs), especially among hospitalized patients with or without urinary tract carcinoma, related commonly to urinary tract abnormalities, urinary catheters or prolonged antibiotic treatment. Although enterococci have been considered more commonly as colonization bacteria in the intestine than virulent agents, they are frequently implicated in UTIs. The high incidence of enterococcal UTIs is associated with several risk factors including age, female gender, previous UTI, diabetes, pregnancy, immunosuppression due to cancer development and progression, renal transplantation and spinal cord injury. Clinical manifestations are usually absent or mild in enterococcal UTIs, which may also become an important source for both bacteremia and endocarditis. Over the last years, the prevalence of multidrug resistant enterococci, particularly vancomycin-resistant E. faecium and E. faecalis has significantly risen worldwide, associated with increased morbidity, limited treatment options and increased health-care costs. In this review, the current knowledge on enterococcal UTIs epidemiology and influence in the corresponding immunocompromised patients is highlighted.

Abstract
AIM We report tofacitinib efficacy and safety in Asia-Pacific patients who participated in the rheumatoid arthritis (RA) clinical development program. METHOD This post-hoc analysis included pooled data from patients with RA in the Asia-Pacific region treated with tofacitinib with/without conventional synthetic disease-modifying antirheumatic drugs in Phase (P)1, 2, 3, and long-term extension (LTE) studies (one LTE ongoing; January 2016 data-cut). Efficacy was assessed over 24 months in patients who received tofacitinib 5 (N = 397) or 10 (N = 382) mg twice daily or placebo (N = 243) in three P2 and five P3 studies. Endpoints included American College of Rheumatology (ACR)20/50/70 responses, Disease Activity Score in 28 joints, erythrocyte sedimentation rate (DAS28-4[ESR]) and Clinical Disease Activity Index (CDAI) remission rates, and change from baseline in Health Assessment Questionnaire-Disability Index (∆HAQ-DI). Safety data pooled over 92 months from one P1, four P2, six P3, and two LTE studies for all tofacitinib doses (N = 1464) included incidence rates (IRs) (patients with events/100 patient-years) for adverse events (AEs) of special interest. RESULTS At month 3, patients receiving tofacitinib 5/10 mg twice daily improved vs placebo in ACR20 (69.2%/77.9% vs 27.5%), ACR50 (36.9%/44.4% vs 9.5%), and ACR70 (15.1%/22.4% vs 2.7%) responses, remission rates for DAS28-4(ESR) (8.5%/18.5% vs 2.6%) and CDAI (6.1%/12.3% vs 0.5%), and ∆HAQ-DI (-0.5/-0.6 vs -0.1); improvements were sustained through 24 months. IRs (95% CI) were 9.4 (8.5, 10.3) for serious AEs, 9.1 (8.3, 10.1) for discontinuations due to AEs, 3.7 (3.2, 4.3) for serious infections, 5.9 (5.2, 6.7) for herpes zoster, and 0.8 (0.6, 1.1) for malignancies (excluding non-melanoma skin cancer). CONCLUSION In Asia-Pacific patients, tofacitinib improved signs/symptoms over 24 months. Safety over 92 months was generally consistent with global tofacitinib studies; however, infection IRs were higher in Asia-Pacific patients.

Abstract
Opportunistic parasites are still important agents causing morbidity and mortality in immunocompromised patients, particularly those living with HIV/AIDS. Few studies in Mexico have attempted to determine the prevalence of opportunistic intestinal parasites causing diarrhea in immunocompromised patients. A study was conducted to determine the intestinal parasites in HIV-positive and HIV-negative immunocompromised patients with diarrhea admitted to a tertiary care hospital in Monterrey, Mexico, from 2014 to 2015. Stool samples were examined for trophozoites, cysts, and eggs using the EGRoPe sedimentation-concentration technique and special techniques (modified Ziehl-Neelsen stain, modified trichrome stain). A total of 56 patients were included. The overall prevalence of intestinal parasitism was 64% (36/56); 22/36 patients were HIV-positive. Prevalence of opportunistic parasites was 69% in HIV-infected patients compared to 44% in HIV-negative patients (P = 0.06). Microsporidia were the most frequently identified parasites (24/36, 67%), followed by Cryptosporidium sp. (6/36, 17%), Sarcocystis sp. (4/36, 11%), Cystoisospora belli (3/36, 8%), and Cyclospora cayetanensis (1/36, 3%). Overall prevalence rates of microsporidiosis and cryptosporidiosis were 43% and 11%, respectively. Among HIV-infected patients, prevalence rates of microsporidiosis and cryptosporidiosis were 48% and 14%, respectively. We also report the first cases of intestinal sarcocystosis in Mexico, all in HIV-infected patients. In conclusion, microsporidia and coccidia are major parasitic agents causing diarrhea in immunocompromised patients, particularly HIV-infected patients.

Abstract
BACKGROUND When opportunistic infections occur, patients with inflammatory bowel disease (IBD) commonly display a significantly increased rate of morbidity and mortality. With increasing use of immunosuppressive agents and biological agents, opportunistic infections are becoming a hot topic in the perspective of drug safety in IBD patients. Despite the well-established role of opportunistic infections in the prognosis of IBD patients, there are few epidemiological data investigating the incidence of opportunis-tic infections in IBD patients in China. Besides, the risk factors for opportunistic infection in Chinese IBD patients remain unclear.
AIM To predict the incidence of opportunistic infections related to IBD in China, and explore the risk factors for opportunistic infections.
METHODS A single-center, prospective study of IBD patients was conducted. The patients were followed for up to 12 mo to calculate the incidence of infections. For each infected IBD patient, two non-infected IBD patients were selected as controls. A conditional logistic regression analysis was used to assess associations between putative risk factors and opportunistic infections, which are represented as odds ratios (OR) and 95% confidence intervals (CIs).
RESULTS Seventy (28.11%) out of 249 IBD patients developed opportunistic infections. Clostridium difficile infections and respiratory syncytial virus infections were found in 24 and 16 patients, respectively. In a univariate analysis, factors such as the severity of IBD, use of an immunosuppressant or immunosuppressants, high levels of fecal calprotectin, and C-reactive protein or erythrocyte sedimentation rate were individually related to a significantly increased risk of opportunistic infection. Multivariate analysis indicated that the use of any immunosuppressant yielded an OR of 3.247 (95%CI: 1.128-9.341), whereas the use of any two immunosuppressants yielded an OR of 6.457 (95%CI: 1.726-24.152) for opportunistic infection. Interestingly, when immunosuppressants were used in combination with infliximab (IFX) or 5-aminosalicylic acid, a significantly increased risk of opportunistic infection was also observed. The relative risk of opportunistic infection was greatest in IBD patients with severe disease activity (OR = 9.090; 95%CI: 1.532-53.941, relative to the remission stage). However, the use of IFX alone did not increase the risk of opportunistic infection.
CONCLUSION Factors such as severe IBD, elevated levels of fecal calprotectin, and the use of immunosuppressive medications, especially when used in combination, are major risk factors for opportunistic infections in IBD patients. The use of IFX alone does not increase the risk of opportunistic infection.

Abstract
BACKGROUND Pneumocystis pneumonia (PCP) is an opportunistic infection occurring in renal transplant patients. Over a 14-month period an increase in PCP cases was identified among our renal transplant cohort. AIM The outbreak population was studied to identify potential risk factors for the development of PCP. METHODS A retrospective analysis of hospital records was carried out, with each case being matched with two case-linked controls. Information was collected on patient demographics, laboratory tests, and hospital visits pre and post development of infection. FINDINGS No patients were receiving PCP prophylaxis at the time of infection and mean time from transplantation to developing PCP was 4.7 years (range: 0.51-14.5). The PCP group had a significantly lower mean estimated glomerular filtration rate than the control group (29.3 mL/min/1.73 m2 vs 70 mL/min-1 (P = 0.0007)). Three patients were treated for active cytomegalovirus (CMV) infection prior to PCP diagnosis and two had active CMV at the time of diagnosis compared to none in the control group (P = 0.001). Those who developed PCP were more likely to have shared a hospital visit with another patient who went on to develop PCP; 37% of clinic visits vs 19% (P = 0.014). CONCLUSION This study highlights the ongoing risk of opportunistic infection several years after transplantation and adds weight to potential person-to-person Pneumocystis jirovecii transmission. Risk factors have been identified which may highlight those most at risk, enabling targeted rather than blanket long-term PCP prophylaxis.

Abstract
Individuals with HIV infection are living longer, and are at risk of autoimmune disorders and cancers associated with aging. Many of these conditions are treated with immunobiologic agents that affect immune function and may increase risk of opportunistic infections (OIs) and other immune disorders in individuals with HIV infection. For example, tumor necrosis factor-alpha inhibitors, used to treat such disorders as Crohn's disease, are associated with risk of tuberculosis and histoplasmosis. Rituximab, used to treat lymphoma, has been associated with progressive multifocal leukoencephalopathy due to JC virus and reactivation of other viral infections. Idealisib, used to treat chronic lymphocytic leukemia, has been associated with Pneumocystis pneumonia, and immune checkpoint inhibitors used to treat a variety of cancers have been associated with a wide range of immune-related adverse effects. Practitioners must maintain high vigilance for OIs and other immune-related disorders in patients with HIV infection who are receiving biologic therapies. This article summarizes a presentation by Peter Chin-Hong, MD, at the IAS-USA continuing education program held in Chicago in May 2018.

Abstract
The aims of this study were to determine the prevalence and phylogenetic relationship of motile Aeromonas spp. that might be pathogenic species for rainbow trout in infected/mix infection cases (based upon different outbreaks on fish farms). A total of 99 motile Aeromonas isolates (and three reference strains) were analysed that were isolated from four different fish species in different sizes of fish (0.1-3,000 g), different months and water temperatures (6.1-21.2°C). The biochemical characteristics of the isolates were determined using conventional tests and a rapid test kit. Additionally, molecular identification was performed using the gyrB housekeeping gene region and with glycerophospholipid-cholesterol acyltransferase polymerase chain reaction (GCAT-PCR). The sequencing results obtained from the gyrB gene region were deposited in the GenBank database, and phylogenetic relationships were determined with the BioNumerics 7.6 database. Nearly half of the Aeromonas isolates that were isolated from rainbow trout showing signs of disease were determined to be possible infectious agents. Aeromonas species exhibit biochemical variability for many characters, so some Aeromonas species tested negative for GCAT-PCR despite that this test was created especially for Aeromonas identification. The phylogenetic tree based upon gyrB contained 10 different phylogroups that were based on 96% cut-off value in gyrB gene region.

Abstract
PURPOSE Bloodstream infections (BSIs) are an important cause of mortality in patients with solid tumors. We conducted a retrospective study to evaluate the epidemiologic profile and mortality of patients with solid tumors who have BSIs and were admitted to Mexico Hospital. This is the first study in Costa Rica and Central America describing the current epidemiologic situation. METHODS We analyzed the infectious disease database for BSIs in patients with solid tumors admitted to Mexico Hospital from January 2012 to December 2014. Epidemiology and mortality were obtained according to microorganism, antibiotic sensitivity, tumor type, and presence of central venous catheter (CVC). Descriptive statistics were used. RESULTS A total of 164 BSIs were recorded, the median age was 58 years, 103 patients (63%) were males, and 128 cases of infection (78%) were the result of gram-negative bacilli (GNB). Klebsiella pneumoniae (21%), Escherichia coli (21%), and Pseudomonas aeruginosa (15%) were the most common microorganisms isolated. Gram-positive cocci (GPC) were found in 36 patients, with the most frequent microorganisms being Staphylococcus aureus (10%) and Staphyloccocus epidermidis (6%). With respect to tumor type, BSIs were more frequent in the GI tract (57%) followed by head and neck (9%) and genitourinary tract (8%). Regarding antibiotic susceptibility, only 17% (GNB) expressed extended-spectrum beta-lactamase and 12% (GPC) had methicillin resistance. Patients with CVCs (n = 59) were colonized mainly by GNB (78%). Overall the mortality rate at 30 days was about 30%. CONCLUSION GNB are the most frequent cause of BSIs in solid tumors and in patients with CVCs. GI cancers had more BSIs than other sites. Mortality and antibiotic sensitivity remained stable and acceptable during this observational period in this Latin American population.

Abstract
BK Polyomavirus-associated nephropathy (BKVAN) has been recognized as an increasing threat in renal transplant patients (RTP) for more than a decade. Reduction in immunosuppression is the mainstay of treatment through various options of treatment has been suggested. Published reports on these protocols have shown mixed results, and no randomized controlled trials have compared one strategy with another. In this context, we hypothesize that the appearance of BKV in the blood compels one to optimize the immunosuppression with possible long-term beneficial effects. We conducted a retrospective study among the RTP being followed up by the Renal Medicine Department at Royal Hospital who tested positive for BKV-polymerase chain reaction and whose immunosuppression was altered with a final aim to get rid of BK viremia, yet avoiding acute rejection. Results were analyzed by the clinical and statistical approach. Extensive literature review was carried out to look into the prevalence, prognosis, and treatment of BKVAN. In all the patients in whom BKV was detected alteration in immunosuppression resulted in eliminating the virus without precipitating acute rejection. The study shows that in the exercise of eliminating BKV by alteration of immunosuppression, we have "tailored" the immunosuppression in each particular RTPs, without precipitating acute rejection.

Abstract
Adult-onset immunodeficiency due to anti-interferon-γ autoantibody is an emerging acquired immunodeficiency with frequent skin manifestations. A retrospective chart review was conducted and identified 41 patients with the syndrome. Skin involvement was detected in 33 (80%) patients, 15 (45%) with infective skin diseases and 27 (82%) with reactive skin disorders. Reactive lesions were mostly neutrophilic dermatoses, e.g. Sweet syndrome. Of note, the presence of neutrophilic dermatoses was highly associated with infections of other sites. An adjusted odds ratio for the existence of infections in patients with neutrophilic dermatoses was 14.79 (95% CI: 5.13, 42.70; p < 0.001). Moreover, neutrophilic dermatoses were significantly correlated with opportunistic infections observed in those with defects in cell-mediated immunity including non-tuberculous mycobacterium and disseminated fungal infection. The odds ratio for opportunistic infections in the presence of neutrophilic dermatoses was 12.35 (95% CI: 5.00, 30.55; p <0.001). Thus, the presence of neutrophilic dermatoses in patients with the syndrome can signal opportunistic infections that warrant physician attention.

Abstract
The risk of infection among patients with psoriasis of varying severity in a broadly representative population remains poorly understood. Using The Health Improvement Network (THIN), an electronic medical records database representative of the general UK population, we performed a cohort study to determine the risks of serious infection, opportunistic infection, and herpes zoster among patients with versus without psoriasis and according to psoriasis severity. We identified 187,258 patients with mild and 12,442 patients with moderate to severe psoriasis based on treatment patterns. Using Cox proportional hazards regression, the adjusted hazard ratios (95% confidence intervals) for serious infection were 1.18 (1.16-1.21) and 1.63 (1.52-1.75) for the mild and moderate to severe psoriasis groups, respectively. Among a nested cohort of 8,569 psoriasis patients with disease severity classified by body surface area involvement, similar results were obtained with the exception of an attenuated but significantly increased risk of serious infection among the moderate to severe psoriasis group (1.27 [1.10-1.47]). Overall, the risks of opportunistic infection and herpes zoster were significantly increased only among the moderate to severe psoriasis group and were associated with immunosuppressive therapy. Our analyses suggest that psoriasis is associated with an increased risk of serious infection, and psoriasis severity is a predictor of serious infection risk.

Abstract
Introduction. The immunosuppression used after transplantation (Tx) is associated with an increased risk of opportunistic infections. In Europe, parasitic infections after Tx are much less common than viral, bacterial and fungal ones. However, diseases caused by parasites are very common in tropical countries. In the last years the number of travellers with immunosuppression visiting tropical countries has increased. Methods. We performed a literature review to evaluate a risk of parasitic infections after Tx in Europe. Results. There is a real risk of parasitic infection in patients after Tx travelling to tropical countries. Malaria, leishmaniasis, strongyloidiasis and schistosomiasis are the most dangerous and relatively common. Although the incidence of these tropical infections after Tx has not increased, the course of disease could be fatal. There are also some cosmopolitan parasitic infections dangerous for patients after Tx. The greatest threat in Europe is toxoplasmosis, especially in heart and bone marrow recipients. The most severe manifestations of toxoplasmosis are myocarditis, encephalitis and disseminated disease. Diarrhoea is one of the most common symptoms of parasitic infection. In Europe the most prevalent pathogens causing diarrhoea are Giardia duodenalis and Cryptosporidium. Conclusions. Solid organ and bone marrow transplantations, blood transfusions and immunosuppressive treatment are associated with a small but real risk of parasitic infections in European citizens. In patients with severe parasitic infection, i.e., those with lung or brain involvement or a disseminated disease, the progression is very rapid and the prognosis is bad. Establishing a diagnosis before the patient's death is challenging.

Abstract
OBJECTIVES Biological DMARDs are widely used in the treatment of rheumatoid arthritis (RA) but their relationship with adverse drug reaction (ADR) is important. RA is now known to increase in incidence and prevalence with age. Our objective was to assess the incidence of severe ADR in the long term, compare safety between the different bDMARDs and identify other possible risk factors for severe ADR in elderly RA patients. METHODS A 14-year retrospective longitudinal study was performed. RA patients followed in an out-patient clinic starting bDMARDs after the age of 65 were included. PRIMARY OUTCOME discontinuation due to a severe ADR related to bDMARDs (etanercept, infliximab, adalimumab, rituximab, golimumab, certolizumab, abatacept and tocilizumab). Covariables: sociodemographic, clinical and therapy. Incidence rates of discontinuation were estimated using survival techniques and comparison between bDMARDs discontinuation rates and other associated factors were run by Cox regression models. RESULTS We analysed 286 courses of bDMARDs therapy in 146 elderly patients (604 patient-years). 78% were women, with a mean age at diagnosis of 66.5±7 years, and a median time to the start of the first bDMARDs of 6±4 years. The incidence of discontinuation due to severe ADR estimated was 10.2% patient-years, with a median survival of around 7 years. The most frequent cause was infections. Etanercept had the lowest risk of severe ADR compared to other bDMARDs. CONCLUSIONS Our study reflects the 'real world' experience in elderly RA patients on bDMARDs, with non-selected patients for a 14-year follow-up.

Abstract
Sarcoidosis is associated with cell-mediated immunodeficiency and treatment of symptomatic sarcoidosis usually includes systemic immunosuppressants. Data relative to incidence, prognosis factors, and outcome of infections are scarce.Retrospective cohort study of 585 patients with biopsy proven sarcoidosis in a tertiary referral specialist clinic, with a nested case-control analysis. Twenty nine patients (4.9%) with severe infections were compared to 116 controls subjects with sarcoidosis, matched according to their gender, ethnicity, age at diagnosis, and treatment with corticosteroids.After a median follow-up of 8 years [range; 1-46], 38 severe infections [mycobacterial infections (n = 14), fungal infections (n = 10), bacterial (n = 8), viral (n = 3) and parasitic (n = 1)] were observed in 30 patients. The incidence of severe infections was 0.71% persons-year (CI 95% 0.5-0.98) and 0.43% persons-year (CI 95% 0.27-0.66). Patients with severe infection were more frequently of male gender (60% vs 46%) and were more likely treated by ≥ 3 immunosuppressive agents (OR = 3.8, IC 95% [1.5-9.64], P = .005) and by cyclophosphamide (OR = 5.55, IC 95% [1.9-16.1], P = .002), and with neurological (OR = 3.36 CI 95% [1.37-8.25], P = .008), or cardiac (OR = 2.65 CI 95% [1.09-6.43], P = .031) involvement of the sarcoidosis, compared to the controls. Two patients died within the 6 months following infection, due to progressive multifocal leucoencephalopathy (n = 1), and of peritonitis (n = 1).Severe infections are observed in 5.1% of our patients with sarcoidosis after a median follow-up of 8 years. Risk factors for severe infections included neurological or cardiac involvement of sarcoidosis, the use of immunosuppressive agents and mainly cyclophosphamide.

Abstract
UNLABELLED Due to the suboptimal persistence to osteoporosis (OP) treatment, factors triggering treatment discontinuation/switching may be causing time-varying confounding. BP treatment was associated with the risk of overall infection in opposite directions in the unweighted Cox model versus the weighted MSM. The discrepancy of effect estimates for overall infection in the MSM suggested there may be time-varying confounding. INTRODUCTION Due to the suboptimal persistence to osteoporosis (OP) treatment, factors triggering treatment discontinuation/switching may be affected by prior treatment and confound the subsequent treatment effect, causing time-varying confounding. METHODS In a US insurance database, the association between joint treatment of bisphosphonates (BP) and other OP medication and the incidence of infections among postmenopausal women was assessed using a marginal structural model (MSM). Stabilized weights were estimated by modeling treatment and censoring processes conditioning on past treatment, and baseline and time-varying covariates. RESULTS BP treatment was associated with the risk of overall infection in opposite directions in the unweighted Cox model {incidence rate ratio [IRR] [95% confidence interval (CI)] = 1.15 [1.14-1.17]} versus the weighted MSM [IRR (95% CI) = 0.79 (0.77-0.81)], but was consistently associated with a lower risk of serious infection in both the unweighted Cox model [IRR (95% CI] = 0.79 (0.78-0.81)) and the weighted MSM [IRR (95% CI) = 0.71 (0.68-0.75)]. Similar results were found when current and past treatments were simultaneously assessed. CONCLUSIONS The discrepancy of effect estimates for overall but not serious infection comparing unweighted models and MSM suggested analyses of composite outcomes with a wide range of disease severity may be more susceptible to time-varying confounding.

Abstract
Considerable progress has been made in the prevention, diagnosis, and management of pediatric patients with invasive fungal disease (IFD). The reported decreasing trend in the incidence of invasive candidiasis (IC) over the past 15 years in both neonates and children has been encouraging. Nevertheless, due to the growing number of immunocompromised children at risk for IFD, this disease continues to be associated with significant morbidity and death and with increased financial burden to the health care system. Therefore, it is important to understand the contemporary epidemiology of IFD. Incidence rates of IFD in children are affected by geographical, population, and time variability. There is an ongoing effort to constantly document and update the incidence of IFD and species distribution among different pediatric populations as a means to direct preventative, diagnostic, and therapeutic resources to the most appropriate subset of patients. Children with a hematologic malignancy or a primary or secondary immunodeficiency, those undergoing solid organ or hematopoietic stem cell transplantation, and premature neonates are the major subsets of pediatric patients at risk of developing IFD. In this review, we focus on fungal disease epidemiology with a specific emphasis on the 2 most common pediatric IFDs, IC and invasive aspergillosis (IA).
