Abstract
Ribosomal RNA gene amplicon sequencing is commonly used to evaluate microbiome profiles in health and disease and document the impact of interventional treatments. Nanopore sequencing is attractive since it can provide greater classification at the species level. However, optimized protocols to target marker genes for bacterial and fungal profiling are needed. To achieve an increased taxonomic resolution, we developed extraction and full-length amplicon PCR-based approaches using Nanopore sequencing. Three lysis conditions were applied to a mock microbial community, including known bacterial and fungal species: ZymoBIOMICS lysis buffer (ML) alone, incorporating bead-beating (MLB) or bead-beating plus MetaPolyzyme enzymatic treatment (MLBE). In profiling of bacteria in comparison to reference data, MLB had more statistically different bacterial phyla and genera than the other two conditions. In fungal profiling, MLB had a significant increase of Ascomycota and a decline of Basidiomycota, subsequently failing to detect Malassezia and Cryptococcus. Also, a principal coordinates analysis plot by the Bray-Curtis metric showed a significant difference among groups for bacterial (P=0.033) and fungal (P=0.012) profiles, highlighting the importance of understanding the biases present in pretreatment. Overall, microbial profiling and diversity analysis revealed that ML and MLBE are more similar than MLB for both bacteria and fungi; therefore, using this specific pipeline, bead-beating is not recommended for whole gene amplicon sequencing. However, ML alone was suggested as an optimal approach considering DNA yield, taxonomic classification, reagent cost and hands-on time. This could be an initial proof-of-concept study for simultaneous human bacterial and fungal microbiome studies.

Abstract
Tuberculosis (TB) is an infectious disease with the burden concentrated in low- and middle-income countries. Systemic lupus erythematosus (SLE) is an autoimmune disease associated with widespread inflammation that is prevalent in some TB endemic areas including East Africa and parts of Southeast Asia. SLE patients are known to be at higher risk of becoming infected with M. tb, developing TB disease. However, the immune mechanisms underlying this susceptibility are not well understood, particularly in the absence of immunosuppressive drugs. We present a pilot study in which we have evaluated intracellular cytokine responses and ex vivo ability to control mycobacterial growth using peripheral blood mononuclear cells (PBMC) collected from SLE patients before and during SLE treatment. After six months of treatment, SLE patients had the highest frequencies of CD8+ T cells, NK cells and NKT cells producing IFN-γ and/or TNF-α. This group also showed superior control of mycobacterial growth, and proinflammatory cytokine-producing NK and NKT cells correlated with mycobacterial growth inhibition at the individual patient level. These findings contribute to a better understanding of autoimmune profiles associated with control of mycobacterial growth in SLE patients, which may inform intervention strategies to reduce risk of TB disease in this population.

Semin Arthritis Rheum 2023; 63:152257. [PMID: 37633041 DOI: 10.1016/j.semarthrit.2023.152257] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 07/25/2023] [Accepted: 08/15/2023] [Indexed: 08/28/2023]
Abstract
OBJECTIVE Invasive fungal infections (IFIs) are life-threatening opportunistic infections in patients with connective tissue disease CTD) that cause significant morbidity and mortality. We attempted to determine the potential risk factors associated with IFIs in CTD. METHODS We systematically searched PubMed, Embase, and the Cochrane Library databases for relevant articles published from the database inception to February 1, 2023. RESULTS Twenty-six studies were included in this systematic review and meta-analysis. Risk factors identified for IFIs were diabetes (odds ratio [OR], 1.62; 95% confidence interval [CI], 1.00 to 2.64), pulmonary diseases (OR 3.43; 95% CI 2.49 to 4.73), interstitial lung disease (ILD; OR, 4.06; 95% CI, 2.22 to 7.41), renal disease (OR, 4.41; 95% CI, 1.84 to 10.59), glucocorticoid (GC) use (OR, 4.15; 95% CI, 2.74 to 6.28), especially moderate to high-dose GC, azathioprine (AZA) use (OR, 1.50; 95% CI, 1.12 to 2.01), calcineurin inhibitor (CNI) use (OR, 2.49; 95% CI, 1.59 to 3.91), mycophenolate mofetil (MMF) use (OR, 2.83; 95% CI, 1.59 to 5.03), cyclophosphamide (CYC) use (OR, 3.35; 95% CI, 2.47 to 4.54), biologics use (OR, 3.43; 95% CI, 2.36 to 4.98), and lymphopenia (OR, 4.26; 95% CI, 2.08 to 8.73). Hydroxychloroquine (HCQ) use reduced risk of IFIs (OR, 0.67; 95% CI, 0.54 to 0.84). Furthermore, 17 of the 26 studies only reported risk factors for Pneumocystis jiroveci pneumonia (PJP) in patients with CTD. Pulmonary disease; ILD; and the use of GC, CNIs, CYC, methotrexate (MTX), MMF and biologics, and lymphopenia increased the risk of PJP, whereas the use of HCQ reduced its risk. CONCLUSION Diabetes, pulmonary disease, ILD, renal disease, use of GC (especially at moderate to high dose) and immunosuppressive drugs, and lymphopenia were found to be associated with significant risk for IFIs (especially PJP) in patients with CTD. Furthermore, the use of HCQ may reduce the risk of IFIs in patients with CTD.

Abstract
BACKGROUND To systematically evaluate the clinical risk factors of patients with systemic lupus erythematosus (SLE) complicated with invasive fungal infection (IFI) among patients. METHODS A meta-analysis was performed of all the literatures germane to estimate the clinical risk factors of patients with SLE complicated with IFI from published clinical trials from 1990 to April 2022. Mean differences, odds ratio and 95% confidence intervals were calculated, and the meta-analysis was conducted with Stata 12.0 software (StataCorp, College Station, TX). RESULTS A total of 14 clinical research involving 1129 patients were included. The results of meta-analysis demonstrated that immunosuppressant, glucocorticoids, systemic lupus erythematosus disease activity index score, antibiotic were risk factors associated with IFI in SLE patients. However, age, sex, course of disease, leukopenia, lymphopenia, C- reactive protein and hypoproteinemia were not the risk factors associated with IFI in patients with SLE. CONCLUSION Our results indicate that immunosuppressant, glucocorticoids, systemic lupus erythematosus disease activity index score, antibiotic were risk factors for IFI in SLE patients. However, high quality of multicenter, large sample size-controlled trials are needed to validate the result.

Abstract
OBJECTIVES To evaluate the inconsistency between clinical diagnosis of death and autopsy findings in adolescents with chronic diseases. METHODS A cross-sectional study including a sample of adolescents' autopsies who died in a pediatric and adolescent tertiary hospital over 18 consecutive years. During this period, there were n = 2912 deaths, and n = 581/2912(20%) occurred in adolescents. Of these, n = 85/581(15%) underwent autopsies and were analyzed. Further results were divided into two groups: Goldman classes I or II (high disagreement between main clinical diagnosis of death and anatomopathological findings, n = 26) and Goldman classes III, IV or V (low or no disagreement between these two parameters, n = 59). RESULTS Median age at death (13.5 [10‒19] vs. 13 [10‒19] years, p = 0.495) and disease duration (22 [0‒164] vs. 20 [0‒200] months, p = 0.931), and frequencies for males (58% vs. 44%, p = 0.247) were similar between class I/II vs. class III/IV/V. The frequency of pneumonia (73% vs. 48%, p = 0.029), pulmonary abscess (12% vs. 0%, p = 0.026), as well as isolation of yeast (27% vs. 5%, p = 0.008), and virus (15% vs. 2%, p = 0.029) identified in the autopsy, were significantly higher in adolescents with Goldman class I/II compared to those with Goldman class III/IV/V. In contrast, cerebral edema was significantly lower in adolescents of the first group (4% vs. 25%, p = 0.018). CONCLUSION This study showed that 30% of the adolescents with chronic diseases had major discrepancies between clinical diagnosis of death and autopsy findings. Pneumonia, pulmonary abscess, as well as isolation of yeast and virus were more frequently identified at autopsy findings in the groups with major discrepancies.

Abstract
Invasive fungal infections cause over 1.5 million deaths worldwide. Despite increases in fungal infections as well as the numbers of individuals at risk, there are no clinically approved fungal vaccines. We produced a "pan-fungal" peptide, NXT-2, based on a previously identified vaccine candidate and homologous sequences from Pneumocystis, Aspergillus,Candida, and Cryptococcus. We evaluated the immunogenicity and protective capacity of NXT-2 in murine and nonhuman primate models of invasive aspergillosis, systemic candidiasis, and pneumocystosis. NXT-2 was highly immunogenic and immunized animals had decreased mortality and morbidity compared to nonvaccinated animals following induction of immunosuppression and challenge with Aspergillus, Candida, or Pneumocystis. Data in multiple animal models support the concept that immunization with a pan-fungal vaccine prior to immunosuppression induces broad, cross-protective antifungal immunity in at-risk individuals.

Abstract
Diagnosis disproportionately affected minority and low-income populations, underscoring the need for broad public health interventions. Fungal infections cause substantial rates of illness and death. Interest in the association between demographic factors and fungal infections is increasing. We analyzed 2019 US hospital discharge data to assess factors associated with fungal infection diagnosis, including race and ethnicity and socioeconomic status. We found male patients were 1.5–3.5 times more likely to have invasive fungal infections diagnosed than were female patients. Compared with hospitalizations of non-Hispanic White patients, Black, Hispanic, and Native American patients had 1.4–5.9 times the rates of cryptococcosis, pneumocystosis, and coccidioidomycosis. Hospitalizations associated with lower-income areas had increased rates of all fungal infections, except aspergillosis. Compared with younger patients, fungal infection diagnosis rates, particularly for candidiasis, were elevated among persons > 65 years of age. Our findings suggest that differences in fungal infection diagnostic rates are associated with demographic and socioeconomic factors and highlight an ongoing need for increased physician evaluation of risk for fungal infections.

Abstract
Objective To evaluate the risk of major infections and the relationship between major infections and mortality in patients with newly diagnosed SLE. Methods A newly diagnosed (<3 months) hospitalised Systemic Lupus Inception Cohort (hSLIC) in our centre during 1 January 2013 and 1 November 2020 was established. All patients were followed up for at least 1 year or until death. Patient baseline characteristics were collected. Major infection events were recorded during follow-up, which were defined as microbiological/clinical-based diagnosis treated with intravenous antimicrobials. The cohort was further divided into a training set and a testing set. Independent predictors of major infections were identified using multivariable logistic regression analysis. Kaplan-Meier survival analyses were conducted. Results Among the 494 patients enrolled in the hSLIC cohort, there were 69 documented episodes of major infections during the first year of follow-up in 67 (14%) patients. The major infection events predominantly occurred within the first 4 months since enrolment (94%, 65/69) and were associated with all-cause mortality. After adjustments for glucocorticoid and immunosuppressant exposure, a prediction model based on SLE Disease Activity Index >10, peripheral lymphocyte count <0.8×109/L and serum creatinine >104 µmol/L was established to identify patients at low risk (3%–5%) or high risk (37%–39%) of major infections within the first 4 months. Conclusions Newly onset active SLE is susceptible to major infections, which is probably due to underlying profound immune disturbance. Identifying high-risk patients using an appropriate prediction tool might lead to better tailored management and better outcome.

Abstract
Background Fungal infections are responsible for >1.5 million deaths globally per year, primarily in those with compromised immune function. This is concerning as the number of immunocompromised patients, especially in those without human immunodeficiency virus (HIV), has risen in the past decade. The purpose of this analysis was to provide the current prevalence and impact of fungal disease in the United States. Methods We analyzed hospital discharge data from the most recent (2018) Healthcare Cost and Utilization Project National Inpatient Sample, and outpatient visit data from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. Costs are presented in 2018 United States (US) dollars. Results In the 35.5 million inpatient visits documented in 2018 in the US, approximately 666 235 fungal infections were diagnosed, with an estimated attributable cost of $6.7 billion. Aspergillus, Pneumocystis, and Candida infections accounted for 76.3% of fungal infections diagnosed, and 81.1% of associated costs. Most fungal disease occurred in patients with elevated risk of infection. The visit costs, lengths of stay, and risks of mortality in this population were more than twice that of those without fungal diagnoses. A further 6.6 million fungal infections were diagnosed during outpatient visits. Conclusions Fungal disease is a serious clinical concern with substantial healthcare costs and significant increases in morbidity and mortality, particularly among predisposed patients. Increased surveillance, standardized treatment guidelines, and improvement in diagnostics and therapeutics are needed to support the rising numbers of at-risk patients.

Abstract
Background: Brain paracoccidioidomycosis (PCM) or neuroparacoccidioidomycosis (NPCM) is a fungal infection of the central nervous system (CNS) caused by Paracoccidioides brasiliensis, a dimorphic fungus. The CNS involvement is through bloodstream dissemination. The association between NPCM and systemic lupus erythematous (SLE) is rare. However, SLE patients are under risk of opportunistic infections given their immunosuppression status. Case Description: The aim of this case report is to present a 37-year-old female with diagnosis of SLE who presented with progressive and persistent headache in the past 4 months accompanied by the right arm weakness with general and neurologic examination unremarkable. The computerized tomography of the head showed left extra-axial parietooccipital focal hypoattenuation with adjacent bone erosion. The brain magnetic resonance imaging reported left parietooccipital subdural collection associated with focal leptomeningeal thickening with restriction to diffusion and peripheral contrast enhancement. The patient underwent a left craniotomy and dura mater biopsy showed noncaseous granulomatosis with multinucleated giant cells with rounded birefringent structures positive for silver stain, consistent with PCM. Management with itraconazole 200 mg daily was started with a total of 12 months of treatment, with patient presenting resolution of headache and right arm weakness. Conclusion: The diagnosis of NPCM is challenging and a high degree of suspicious should be considered in patients with persistent headache and immunosuppression.

Abstract
INTRODUCTION Little is known about the relationship between exposure levels of mycophenolic acid (MPA), the active metabolite of mycophenolate mofetil (MMF), and comorbidities of systemic lupus erythematosus (SLE) in children. This study aims to explore this association. METHODS Longitudinal data from SLE children, who were taking MMF for immunosuppression and under therapeutic drug monitoring (TDM), were retrospectively collected. Area under the concentration-time curve of mycophenolic acid (MPA) over 24 hours (AUC0-24h) was estimated with Bayesian methods. Logistic regression and random forest models were used to explore the association between comorbidities and MPA exposure levels. RESULTS This study included 107 children with 358 times of follow-up (median age 169.02 months). The incidence of diabetes, acute kidney injury (AKI), or pneumonia was significantly associated with AUC0-24h (odds ratio [OR] 0.991, 95% confidence interval [CI] 0.982-0.999), SLE duration (OR 1.012, 95% CI 1.002-1.022), lymphocyte percentage (OR 0.959, 95% CI 0.925-0.991), plasma albumin levels (OR 0.891, 95% CI 0.843-0.940), use of aspirin (OR 0.292, 95% CI 0.126-0.633) and hydroxychloroquine (OR 0.407, 95% CI 0.184-0.906). The random forest model showed that albumin and AUC0-24h were two important predictors. The case group (with the three comorbidities) had a mean AUC0-24h of 73.63 mg · h/L, while the control group had a mean AUC0-24h of 100.39 mg · h/L. CONCLUSIONS Increased levels of MPA exposure are associated with decreased incidence odds of diabetes, AKI or pneumonia in SLE children. An AUC0-24h of 100.39 mg · h/L or an AUC0-12h of 50.20 mg · h/L could be used as the targeted exposure level for clinical practice.

Abstract
Growing evidence suggests that autoimmune diseases (AIDs) are risk factors for cryptococcal meningitis (CM). Therefore, understanding the epidemiological and clinical profile of CM in patients with AIDs is important. This meta-analysis assessed the prevalence, clinical profiles, and clinical outcomes of CM in AIDs. Studies on CM in patients with AIDs were searched for in PubMed, EMBASE, Web of Science, and China National Knowledge Infrastructure, and meta-analyses were performed using the statistical program of R. Nineteen studies with 36,631 patients with AIDs were analyzed. The overall pooled CM prevalence was 0.4% (95% confidence interval [CI], 0.3-0.6%), 90.7% of which occurred in female patients. Thirteen studies with 77 patients with AIDs diagnosed with CM were analyzed, and the mortality rate was 26.7% (95% CI, 9.5-47.2%). Of patients with systemic lupus erythematosus, 30.1% of CM cases were initially misdiagnosed (95% CI, 0-65.6%). The primary symptom of CM with AIDs was headache (99.4%; 95% CI, 92.1-100%), followed by fever (93.7%; 95% CI, 82.8-100%) and vomiting (37.2%; 95% CI, 13.2-61.2%). The prevalence of CM infections among patients with AIDs should not be underestimated despite non-specific clinical presentations as there were fatal outcomes. Our results suggest that more research is needed to understand the relationship between AIDs and CM, and clinical trials are necessary to improve treatment strategies.

Abstract
Childhood-onset systemic lupus erythematosus (cSLE) is a prototype of a multisystemic, inflammatory, heterogeneous autoimmune condition. This disease is characterized by simultaneous or sequential organ and system involvement, with unpredictable flare and high levels of morbidity and mortality. Racial/ethnic background, socioeconomic status, cost of medications, difficulty accessing health care, and poor adherence seem to impact lupus outcomes and treatment response. In this article, the management of cSLE patients is updated. Regarding pathogenesis, a number of potential targets for drugs have been studied. However, most treatments in pediatric patients are off-label drugs with recommendations based on inadequately powered studies, therapeutic consensus guidelines, or case series. Management practices for cSLE patients include evaluations of disease activity and cumulative damage scores, routine non-live vaccinations, physical activity, and addressing mental health issues. Antimalarials and glucocorticoids are still the most common drugs used to treat cSLE, and hydroxychloroquine is recommended for nearly all cSLE patients. Disease-modifying antirheumatic drugs (DMARDs) should be standardized for each patient, based on disease flare and cSLE severity. Mycophenolate mofetil or intravenous cyclophosphamide is suggested as induction therapy for lupus nephritis classes III and IV. Calcineurin inhibitors (cyclosporine, tacrolimus, voclosporin) appear to be another good option for cSLE patients with lupus nephritis. Regarding B-cell-targeting biologic agents, rituximab may be used for refractory lupus nephritis patients in combination with another DMARD, and belimumab was recently approved by the US Food and Drug Administration for cSLE treatment in children aged > 5 years. New therapies targeting CD20, such as atacicept and telitacicept, seem to be promising drugs for SLE patients. Anti-interferon therapies (sifalimumab and anifrolumab) have shown beneficial results in phase II randomized control trials in adult SLE patients, as have some Janus kinase inhibitors, and these could be alternative treatments for pediatric patients with severe interferon-mediated inflammatory disease in the future. In addition, strict control of proteinuria and blood pressure is required in cSLE, especially with angiotensin-converting enzyme inhibitor and angiotensin receptor blocker use.

Genetic and immunologic findings in children with recurrent aphthous stomatitis with systemic inflammation. Pediatr Rheumatol Online J 2021; 19:70. [PMID: 33971891 PMCID: PMC8111718 DOI: 10.1186/s12969-021-00552-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Accepted: 04/14/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Recurrent aphthous stomatitis with systemic signs of inflammation can be encountered in inflammatory bowel disease, Behçet's disease (BD), Systemic Lupus Erythematosus (SLE). In addition, it has been proposed that cases with very early onset in childhood can be underpinned by rare monogenic defects of immunity, which may require targeted treatments. Thus, subjects with early onset recurrent aphthous stomatitis receiving a clinical diagnosis of BD-like or SLE-like disease may deserve a further diagnostic workout, including immunologic and genetic investigations. OBJECTIVE To investigate how an immunologic, genetic and transcriptomics assessment of interferon inflammation may improve diagnosis and care in children with recurrent aphthous stomatitis with systemic inflammation. METHODS Subjects referred to the pediatric rheumatologist for recurrent aphthous stomatitis associated with signs of systemic inflammation from January 2015 to January 2020 were enrolled in the study and underwent analysis of peripheral lymphocyte subsets, sequencing of a 17-genes panel and measure of interferon score. RESULTS We enrolled 15 subjects (12 females, median age at disease onset 4 years). The clinical diagnosis was BD in 8, incomplete BD in 5, BD/SLE overlap in 1, SLE in 1. Pathogenic genetic variants were detected in 3 patients, respectively 2 STAT1 gain of function variants in two patients classified as BD/SLE overlap and SLE, and 1 TNFAIP3 mutation (A20 haploinsufficiency) in patients with BD. Moreover 2 likely pathogenic variants were identified in DNASE1L3 and PTPN22, both in patients with incomplete BD. Interferon score was high in the two patients with STAT1 GOF mutations, in the patient with TNFAIP3 mutation, and in 3 genetic-negative subjects. In two patients, the treatment was modified based on genetic results. CONCLUSIONS Although recurrent aphthous stomatitis associated with systemic inflammation may lead to a clinical diagnosis of BD or SLE, subjects with early disease onset in childhood deserve genetic investigation for rare monogenic disorders. A wider genetic panel may help disclosing the genetic background in the subset of children with increased interferon score, who tested negative in this study.

Abstract
BACKGROUND Invasive fungal infections (IFIs) in the United States are chronically underdiagnosed and a lack of coordinated surveillance makes the true burden of disease difficult to determine. The purpose of this analysis was to capture mortality-associated burden of risk conditions and fungal infections. METHODS We analyzed data from the National Vital Statistics System from 1999-2018 to estimate the mortality attributed to risk conditions and related fungal disease. RESULTS The number of risk conditions associated with fungal disease is steadily rising in the United States with 1,047,422 diagnoses at time of death in 2018. While fungal disease decreased substantially from 1999 to 2010, primarily due to the control of HIV infection, the number deaths with fungal diagnosis has increased in the non-HIV cohort, with significant increases in patients with diabetes, cancer, immunosuppressive disorders, or sepsis. CONCLUSION The landscape of individuals at risk for serious fungal diseases is changing, with a continued decline in HIV-associated incidence, but increased diagnoses in patients with cancer, sepsis, immunosuppressive disorders, and influenza. Additionally, there is an overall increase in the number of fungal infections in recent years, indicating a failure to control fungal disease mortality in these new immunocompromised cohorts. Improvement in prevention and management of fungal diseases is needed to control morbidity and mortality in the rising number of immunocompromised and at-risk patients in the United States.

Abstract
OBJECTIVE Infection is one of the major causes of morbidity and mortality in systemic lupus erythematosus (SLE) patients. We conducted a systematic review and meta-analysis to investigate the clinical characteristics and risk factors of infection in SLE by comparing demographic factors, laboratory data, clinical features, and therapeutic factors between infection and non-infection SLE patients. METHODS PubMed, Embase, and Cochrane databases were searched systematically without restricting the language or year (up to September 2019) by using MeSH terms and keywords pertaining to SLE and infection. Three independent reviewers selected all observational studies based on the established inclusion criteria. Odds ratio (OR) and standardized mean difference (SMD) along with 95% confidence intervals (CI) were used and the analyses were carried out by using a random/fixed-effects model. When necessary, different subgroup and sensitivity analyses were conducted. Study quality was assessed by the modified version (nine-star scoring system) of the Newcastle-Ottawa Scale (NOS) and publication bias was evaluated by funnel plots, and Egger's and Begg's tests. RESULTS In total, we included 39 studies (3709 infection SLE patients and 10526 non-infection SLE patients) based on the inclusion criteria. Compared with the SLE patients without infection, we found that infected SLE patients had a significantly higher incidence rate of the following: 1) lymphopenia (OR = 2.738 95%CI (1.017-7.376), P = 0.046, I2 = 81.4%), 2) thrombocytopenia (OR = 1.61 95%CI (1.4-1.85), P<0.001, I2 = 0%), 3) anemia (OR = 2.294 95%CI (1.402-3.755), P = 0.001, I2 = 83.0%), 4) hypoproteinemia (OR = 2.336 95%CI (1.408-3.876), P = 0.001, I2 = 84.2%), 5) C3 consumed (OR = 1.890 95%CI (1.190-3.002), P = 0.007, I2 = 77.4%), 6) diabetes mellitus (OR = 3.890 95%CI (2.450-6.160), P < 0.001, I2 = 0%), 7) elevated creatinine (OR = 1.954 95%CI (1.646-2.320), P < 0.001, I2 = 0.0%), 8) renal involvement (OR = 2.692 95%CI (2.000-3.623), P < 0.001, I2 = 76.0%), 9) serositis (OR = 3.877 95%CI (0.995-15.110), P = 0.051, I2 = 79.1%), and 10) use of steroid immunosuppressants (OR = 3.116 95%CI (1.959-4.957), P < 0.001, I2 = 77.9%). Furthermore, infected SLE patients had a significantly higher mean dose of prednisone (SMD = 2.088 95%CI (1.196-2.981), P < 0.001, I2 = 97.8%). In addition, SLE patients with infection showed a significantly lower incidence of antimalarial drug use (OR = 0.634 95%CI (0.451-0.892), P = 0.009, I2 = 56.0%). Infected SLE patients had a significantly higher level of 1) 24-h urinary protein (SMD = 0.560 95%CI (0.300-0.810), P < 0.001, I2 = 0%), 2) CRP (SMD = 0.437 95%CI (0.184-0.691), P = 0.001, I2 = 68.6%), and 3) SLE Collaborating Clinics damage index (SDI) (SMD = 0.451 95%CI (0.238-0.664), P < 0.001, I2 = 0.0%), along with a significantly lower level of albumin (SMD = -0.400 95%CI (-0.610--0.200), P < 0.001, I2 = 0.0%). After adjustment for false discovery rate (FDR), lymphopenia and serositis were no longer associated with the occurrence of infection; however, the remaining factors were still associated with infection in SLE. According to the nine-star scoring system of NOS, 71.79% of the studies were considered as high methodological quality (low risk of bias). No significant publication bias, except for renal involvement, was detected from funnel plots or Egger's and Begg's test, while this publication bias of renal involvement did not impact the pooled estimates. CONCLUSION We identified many factors including thrombocytopenia, anemia, hypoproteinemia, hypocomplementemia, hypoalbuminemia, higher level of CRP, higher SDI score, renal involvement and diabetes mellitus that were associated with infection in SLE patients. In addition, glucocorticoids (especially high-dose) and immunosuppressants (e.g. cyclophosphamide) rendered SLE patients more susceptible to infection, while antimalarial drug administration (hydroxychloroquine) was a protective factor against infection in SLE patients. SLE patients with the above clinical characteristics and risk factors might be at high risk from infection, which might contribute to the early identification of infection in SLE patients for better prognosis.

Abstract
Objective This study aimed to investigate the clinical characteristics and risk factors associated with severe pneumonia in systemic lupus erythematosus (SLE) patients from China. Method We performed a retrospective study in 112 hospitalized SLE patients who had had pneumonia for 8 years. The primary outcome was severe pneumonia, followed by descriptive analysis, group comparison and bivariate analysis. Results A total of 28 SLE patients were diagnosed with severe pneumonia, with a ratio of 5:23 between men and women. The mean age at diagnosis was 44.36 ± 12.389 years. The median disease duration was 72 months, and the median SLE Disease Activity Index 2000 (SLEDAI 2K) score was 8. The haematological system was the most affected, with an incidence of anaemia in 85.7% of cases and thrombocytopenia in 75% of cases, followed by lupus nephritis in 50% of cases and central nervous system involvement in 10.71% of cases. Cultured sputum specimens were positive in 17 (68%) SLE patients with severe pneumonia, of whom nine (36%) were cases of fungal infection, five (20%) were cases of bacterial infection and three (12%) were cases of mixed infection. Using multivariate logistic regression analysis, we concluded that a daily dosage of prednisone (>10 mg; odds ratio (OR) = 3.193, p = 0.005), a low percentage of CD4+ T lymphocytes (OR = 0.909, p = 0.000), a high SLEDAI 2K score (OR = 1.182, p = 0.001) and anaemia (OR = 1.182, p = 0.001) were all independent risk factors for pneumonia in SLE patients, while a low percentage of CD4+ T lymphocytes (OR = 0.908, p = 0.033), a daily dose of prednisone of >10 mg (OR = 35.67, p = 0.001) were independent risk factors for severe pneumonia in SLE patients. Conclusion Severe pneumonia is not rare in lupus, and is associated with high mortality and poor prognosis. Monitoring CD4+ T-cell counts and giving a small dose of glucocorticoids can reduce the occurrence of severe pneumonia and improve the prognosis of patients with lupus.

Fatal Disseminated Aspergillosis in a Patient with Systemic Lupus Erythematosus. Case Rep Infect Dis 2020; 2020:9623198. [PMID: 32181030 PMCID: PMC7066410 DOI: 10.1155/2020/9623198] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2019] [Revised: 01/20/2020] [Accepted: 02/05/2020] [Indexed: 12/17/2022] Open
Abstract
Patients with systemic lupus erythematosus (SLE) are at increased risk for infection including opportunistic infections. Fungal infection in particular can be difficult to diagnose and treat and often can be life-threatening in the immunocompromised patient. We present a case in which a patient with SLE presented to the hospital with shortness of breath and cough. Throughout the hospital course, the patient's condition continued to decline leading to acute respiratory failure, and eventually, the patient expired. Postmortem autopsy revealed invasive fungal aspergillosis infection involving the heart, lungs, and brain. Earlier diagnosis and treatment with empiric antifungals may improve survival in these patients.

Abstract
OBJECTIVES To describe the epidemiological, clinical and microbiological characteristics and mortality of patients with Candida bloodstream infection and systemic autoimmune diseases. METHODS We performed a retrospective multicenter study of candidemia in adults with systemic autoimmune diseases between 2010 and 2016. RESULTS Among 1040 patients with candidemia, 36 (3.5%) had a systemic autoimmune disease. The most common systemic autoimmune disease was rheumatoid arthritis (27.8%). The most common species was Candida albicans (66.7%). Twenty-two (61.1%) patients received a corticosteroid therapy and nine (25%) received an immunosuppressive therapy at the time of candidemia. The mortality rate was 27.8%. CONCLUSIONS Systemic autoimmune diseases are not common in patients with candidemia. The unadjusted mortality rate was comparable to other candidemia studies in the general population.

Abstract
OBJECTIVES To evaluate mortality in adolescents and young adult patients with chronic diseases followed in a Latin American tertiary hospital. METHODS A cross-sectional retrospective study was performed in a tertiary/academic hospital in the state of São Paulo, Brazil. Death occurred in 529/2850 (18.5%) adolescents and young adult patients with chronic diseases, and 25/529 (4.7%) were excluded due to incomplete medical charts. Therefore, 504 deaths were evaluated. RESULTS Deaths occurred in 316/504 (63%) of early adolescent patients and in 188/504 (37%) of late adolescent/young adult patients. Further comparisons between early adolescents (n=316) and late adolescent/young adult patients (n=188) with pediatric chronic diseases at the last hospitalization showed that the median disease duration (22.0 [0-173] vs. 43.0 [0-227] months, p<0.001) was significantly lower in early adolescents vs. late adolescent/young adult patients. The median number of previous hospitalizations was significantly lower in the former group (4.0 [1-45] vs. 6.0 [1-52], p<0.001), whereas the last hospitalization in intensive care unit was significantly higher (60% vs. 47%, p=0.003). Regarding supportive measures, palliative care was significantly lower in the younger group compared to the older group (33% vs. 43%, p=0.02). The frequencies of renal replacement therapy (22% vs. 13%, p=0.02), vasoactive agents (65% vs. 54%, p=0.01), and transfusion of blood products (75% vs. 66%, p=0.03) were significantly higher in the younger group. The five most important etiologies of pediatric chronic diseases were: neoplasias (54.2%), hepatic diseases/transplantation (10%), human immunodeficiency virus (5.9%), and childhood-onset systemic lupus erythematosus and juvenile idiopathic arthritis (4.9%). Autopsy was performed in 58/504 (11%), and discordance between clinical and postmortem diagnoses was evidenced in 24/58 (41.3%). CONCLUSIONS Almost 20% of deaths occurred in adolescents and young adults with distinct supportive care and severe disease patterns. Discordance between clinical diagnosis and autopsy was frequently observed.

Abstract
INTRODUCTION Treatment of lupus nephritis class III, IV and V with immunosuppressive therapy increases patient survival but poses a risk of infection-related mortality. This study was conducted to evaluate risk factors for fatal infection in children with lupus nephritis in under-resourced areas. METHODS Medical records of patients, who were admitted to a tertiary-care university-based hospital from January 2002 to July 2018 with the diagnosis of systemic lupus erythematosus, were reviewed. Only patients aged less than 18 years with lupus nephritis and documented infection were included in the study. The primary outcome was infection-associated mortality. The logistic regression model was used to identify independent variables associated with fatal infection. Predicted probabilities of infection-related mortality adjusted for factors significant in multivariate analysis were calculated using marginal effects at representative values. RESULTS Infection-related deaths occurred in 27 of 179 patients (15.1%). Hospital-acquired infections occurred in 72 of 375 episodes of hospital admissions (19.2%) and 13 hospital-acquired infections (18.1%) resulted in fatal infection. Invasive fungal infections were the leading cause of death (44.4%) and pulmonary infections were the predominant site (55.5%). Haemoglobin levels and glomerular filtration rates were significantly lower in deceased versus surviving patients. Percentages of patients with hospital-acquired infections, invasive fungal infections and pulmonary infections were significantly higher in deceased than surviving patients. Urine protein, the neutrophil-to-lymphocyte ratio, cumulative methylprednisolone dose and daily prednisolone dose were significantly higher in deceased than surviving patients. In multivariate analysis, a neutrophil-to-lymphocyte ratio more than 20, invasive fungal infections and high daily prednisolone dose were independently predictive of fatal infection with adjusted odds ratio of 3.02 (95% confidence interval 1.02-8.97, p = 0.04), 15.08 (95% confidence interval 4.72-48.24, p < 0.001) and 1.03 (95% confidence interval 1.01-1.06, p = 0.04), respectively. A high daily prednisolone dose intensified the impact of invasive fungal infections and high neutrophil-to-lymphocyte ratio on predicted probability of infection-associated mortality. CONCLUSIONS Prevention of invasive fungal infections and minimization of daily prednisolone should be emphasized in routine clinical practice of children with lupus nephritis in under-resourced areas to achieve better survival. Children with lupus nephritis and a high neutrophil-to-lymphocyte ratio should be under cautious surveillance for infection.

Abstract
SCOPE Presenting symptoms, distributions and patterns of diseases and vulnerability to invasive aspergillosis (IA) are similar between children and adults. However, differences exist in the epidemiology and underlying conditions, the usefulness of newer diagnostic tools, the pharmacology of antifungal agents and in the evidence from interventional phase 3 clinical trials. Therefore, the European Society for Clinical Microbiology and Infectious Diseases (ESCMID) and the European Confederation of Medical Mycology (ECMM) have developed a paediatric-specific guideline for the diagnosis and management of IA in neonates and children. METHODS Review and discussion of the scientific literature and grading of the available quality of evidence was performed by the paediatric subgroup of the ESCMID-ECMM-European Respiratory Society (ERS) Aspergillus disease guideline working group, which was assigned the mandate for the development of neonatal- and paediatric-specific recommendations. QUESTIONS Questions addressed by the guideline included the epidemiology of IA in neonates and children; which paediatric patients may benefit from antifungal prophylaxis; how to diagnose IA in neonates and children; which antifungal agents are available for use in neonates and children; which antifungal agents are suitable for prophylaxis and treatment of IA in neonates and children; what is the role of therapeutic drug monitoring of azole antifungals; and which management strategies are suitable to be used in paediatric patients. This guideline provides recommendations for the diagnosis, prevention and treatment of IA in the paediatric population, including neonates. The aim of this guideline is to facilitate optimal management of neonates and children at risk for or diagnosed with IA.

Abstract
OBJECTIVE Patients with systemic lupus erythematosus (SLE) are susceptible to herpes simplex virus (HSV) infection, which occasionally leads to severe complications including meningoencephalitis and keratitis. However, few attempts to analyse the associated incidence and risk factors have been made. METHODS We enrolled patients with SLE recorded between 1997 and 2012 and compared the incidence rate (IR) of severe HSV infection, including meningoencephalitis, septicaemia, ocular and visceral involvement, and other specific complications demanding hospitalisation, with that of a non-SLE cohort. A Cox multivariate proportional hazards model was applied to analyse the risk factors of severe HSV infection in patients with SLE. RESULTS A total of 122 520 subjects (24 504 patients with SLE and 98 016 age-matched and sex-matched non-SLE controls) were included, and a higher IR of severe HSV infection was revealed in the SLE group (IR ratio=3.93, p<0.001). In patients with SLE, previous oral and genital infection (HR=2.29, p=0.049), intravenous steroid pulse therapy (HR=5.32, p<0.001) and daily oral dose of over 7.5 mg of prednisolone (HR=1.59, p=0.024) were independent risk factors for severe HSV infection, whereas age of ≤18 (HR=0.45, p=0.029) was a protective factor. CONCLUSIONS Patients with SLE are at higher risk of severe HSV infection, and related risk factors include being older than 18 years, having a history of HSV mucocutaneous infection, recent receipt of steroid pulse therapy and a daily oral dose of steroid over 7.5 mg prednisolone.

Abstract
Objective To investigate the characteristics and associated factors of invasive fungal disease in patients with systemic lupus erythematosus from Southern China. Methods A retrospective study was performed. Demographic and clinical characteristics, laboratory data, and radiographic manifestations were recorded. Results A total of 45 lupus patients with invasive fungal disease (incidence 1.1%) were included. Twenty-three cases (51.1%) were infected with mold and 22 cases (48.9%) with yeast. Aspergillus spp. (44.4%) and Cryptococcus spp. (33.3%) were common. Aspergillosis mainly occurred in the lung. Cryptococcosis developed in the lung (40.0%), meninges (46.7%) and bloodstream (13.3%). Compared with yeast infection, mold infection tended to develop in patients with active lupus nephritis (65.2% vs. 31.8%, P = 0.03) and the mortality rate was higher (20.0% vs. 0%, P = 0.001). Co-infection with bacteria, virus or superficial fungi occurred in 12 patients (26.7%). Multivariate logistic regression analysis indicated that lymphopenia (odds ratio 2.65, 95% confidential interval 1.14–6.20, P = 0.02) and an accumulated dose of glucocorticoid (odds ratio 1.58, 95% confidence interval 1.10–2.25, P = 0.01) was associated with invasive fungal disease in lupus patients. Conclusion Mold infection tended to develop in patients with active lupus disease with high mortality. Co-infection is not rare. Lymphopenia and an accumulated dose of glucocorticoid are associated with invasive fungal disease in lupus patients.

Abstract
To assess epidemiology and management practices of Latin America Pediatric Rheumatologists (LAPR) about childhood-onset systemic lupus erythematosus (cSLE). A cross-sectional study was performed in 288 LAPR PANLAR members based on online survey about cSLE practices. The response rate of web-based survey by LAPR was 170/288(59%) and the majority worked in university hospitals (63%). The ACR and/or SLICC classification criteria (99%) and disease activity tools (97%) were almost universally used by LAPR, whereas damage index (70%) and CHAQ (58%) instruments were less frequently used. Laboratory exams, diagnostic imaging, and biopsies were generally available (> 75%), however low availability for densitometry (66%). Drug access was excellent for the most common prescribed medications (> 75%), except for belimumab (11%). Emerging mosquito-borne diseases were also reported: dengue (20%), chikungunya (11%), and Zika (8%). Groups were further divided in two, according to the median number of cSLE patients followed by LAPR in the last year: groups A and B (≥ 25 and < 25, respectively). Frequencies of condom in combination with other contraceptive methods were significantly higher in group A than B (p = 0.01). The frequencies of reported pregnancy (p < 0.001) and non-adherence to therapy were significantly higher in group A (p = 0.023). Alcohol intake (p = 0.004) and illicit drug use (p = 0.007) were also reported more frequently by LAPR of group A in at least one cSLE patient. This first large web-based survey demonstrated an overall excellent access for diagnosis and therapy by LAPR, probably related to their high rate of practices in tertiary care of university hospitals. Adherence to therapy, pregnancy, and substance abuse was identified as major challenges in this population, particularly in larger centers.

Abstract
Introduction Systemic lupus erythematosus is an autoimmune disease with multi-organ involvement. Complications, such as invasive fungal infections usually occur in patients with a greater severity of the disease. Objective The objective of this study was to determine the prevalence and risk variables associated with invasive fungal infections in a Colombian systemic lupus erythematosus population. Materials and methods A cross-sectional, retrospective study that evaluated patients with systemic lupus erythematosus for six years. The primary outcome was invasive fungal infection. Descriptive, group comparison and bivariate analysis was performed using Stata 12.0 software. Results Two hundred patients were included in this study; 84.5% of the patients were women and the median age was 36 years; 68% of the subjects had haematological complications; 53.3% had nephropathy; 45% had pneumopathy and 28% had pericardial impairment; 7.5% of patients had invasive fungal infections and the most frequently isolated fungus was Candida albicans. Pericardial disease, cyclophosphamide use, high disease activity, elevated ESR, C3 hypocomplementemia, anaemia and lymphopenia had a significant association with invasive fungal infection ( P < 0.05). Conclusions We describe for the first time the prevalence of invasive fungal infection in a Colombian population with systemic lupus erythematosus, which was higher than that reported in other latitudes. In this population the increase in disease activity, the presence of pericardial impairment and laboratory alterations (anaemia, lymphopenia, increased ESR and C3 hypocomplementemia) are associated with a greater possibility of invasive fungal infections. Regarding the use of drugs, unlike other studies, in the Colombian population an association was found only with the previous administration of cyclophosphamide. In addition, patients with invasive fungal infections and systemic lupus erythematosus had a higher prevalence of mortality and hospital readmission compared with patients with systemic lupus erythematosus without invasive fungal infection.

Abstract
OBJECTIVE To investigate the nationwide prevalence and incidence of serious infections among children with systemic lupus erythematosus (SLE) enrolled in Medicaid, the US health insurance program for low-income patients. METHODS From Medicaid claims (2000-2006) we identified children ages 5 to <18 years with SLE (≥3 International Classification of Diseases, Ninth Revision [ICD-9] codes of 710.0, each >30 days apart) and lupus nephritis (LN; ≥2 ICD-9 codes for kidney disease on/after SLE codes). From hospital discharge diagnoses, we identified infection subtypes (bacterial, fungal, and viral). We calculated incidence rates (IRs) per 100 person-years, mortality rates, and hazard ratios adjusted for sociodemographic factors, medications, and preventive care. RESULTS Among 3,500 children with identified SLE, 1,053 serious infections occurred over 10,108 person-years; the IR was 10.42 per 100 person-years (95% confidence interval [95% CI] 9.80-11.07) among all those with SLE and 17.65 per 100 person-years (95% CI 16.29-19.09) among those with LN. Bacterial infections were most common (87%, of which 39% were bacterial pneumonias). In adjusted models, African Americans and American Indians had higher rates of infections compared with white children, and those with comorbidities or receiving corticosteroids had higher infection rates than those without. Males had lower rates of serious infections compared to females. The 30-day postdischarge mortality rate was 4.4%. CONCLUSION Overall, hospitalized infections were very common in children with SLE, with bacterial pneumonia being the most common infection. Highest infection risks were among African American and American Indian children, those with LN, comorbidities, and those taking corticosteroids.

Abstract
Objectives Anti-ribosomal P protein (anti-P) autoantibodies are highly specific for systemic lupus erythematosus (SLE). However, the evaluation of this autoantibody in childhood-onset SLE (cSLE) populations has been limited to a few small series, hampering the interpretation of the clinical and laboratorial associations. Therefore, the objective of this multicenter cohort study was to evaluate demographic, clinical/laboratorial features, and disease damage score in cSLE patients with and without the presence of anti-P antibody. Methods This was a retrospective multicenter study performed in 10 pediatric rheumatology services of São Paulo state, Brazil. Anti-P antibodies were measured by ELISA in 228 cSLE patients. Results Anti-P antibodies were observed in 61/228 (27%) cSLE patients. Frequencies of cumulative lymphadenopathy (29% vs. 15%, p = 0.014), acute confusional state (13% vs. 5%, p = 0.041), mood disorder (18% vs. 8%, p = 0.041), autoimmune hemolytic anemia (34% vs. 15%, p = 0.001), as well as presence of anti-Sm (67% vs. 40%, p = 0.001), anti-RNP (39% vs. 21%, p = 0.012) and anti-Ro/SSA antibodies (43% vs. 25%, p = 0.016) were significantly higher in cSLE patients with anti-P antibodies compared to those without these autoantibodies. A multiple regression model revealed that anti-P antibodies were associated with autoimmune hemolytic anemia (odds ratio (OR) = 2.758, 95% confidence interval (CI): 1.304-5.833, p = 0.008) and anti-Sm antibody (OR = 2.719, 95% CI: 1.365-5.418, p = 0.004). The SLICC/ACR damage index was comparable in patients with and without anti-P antibodies ( p = 0.780). Conclusions The novel association of anti-P antibodies and autoimmune hemolytic anemia was evidenced in cSLE patients and further studies are necessary to determine if anti-P titers may vary with this hematological manifestation.

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).

Abstract
Invasive fungal diseases (IFDs) are devastating opportunistic infections that result in significant morbidity and death in a broad range of pediatric patients, particularly those with a compromised immune system. Recognizing them can be difficult, because nonspecific clinical signs and symptoms or isolated fever are frequently the only presenting features. Therefore, a high index of clinical suspicion is necessary in patients at increased risk of IFD, which requires knowledge of the pediatric patient population at risk, additional predisposing factors within this population, and the clinical signs and symptoms of IFD. With this review, we aim to summarize current knowledge regarding the recognition and clinical presentation of IFD in neonates and children.

Abstract
Objective The objective of this study was to assess outcomes of childhood systemic lupus erythematosus (cSLE) in three different age groups evaluated at last visit: group A early-onset disease (<6 years), group B school age (≥6 and <12 years) and group C adolescent (≥12 and <18 years). Methods An observational cohort study was performed in ten pediatric rheumatology centers, including 847 cSLE patients. Results Group A had 39 (4%), B 395 (47%) and C 413 (49%). Median disease duration was significantly higher in group A compared to groups B and C (8.3 (0.1-23.4) vs 6.2 (0-17) vs 3.3 (0-14.6) years, p < 0.0001). The median Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR-DI) (0 (0-9) vs 0 (0-6) vs 0 (0-7), p = 0.065) was comparable in the three groups. Further analysis of organ/system damage revealed that frequencies of neuropsychiatric (21% vs 10% vs 7%, p = 0.007), skin (10% vs 1% vs 3%, p = 0.002) and peripheral vascular involvements (5% vs 3% vs 0.3%, p = 0.008) were more often observed in group A compared to groups B and C. Frequencies of severe cumulative lupus manifestations such as nephritis, thrombocytopenia, and autoimmune hemolytic anemia were similar in all groups ( p > 0.05). Mortality rate was significantly higher in group A compared to groups B and C (15% vs 10% vs 6%, p = 0.028). Out of 69 deaths, 33/69 (48%) occurred within the first two years after diagnosis. Infections accounted for 54/69 (78%) of the deaths and 38/54 (70%) had concomitant disease activity. Conclusions This large multicenter study provided evidence that early-onset cSLE group had distinct outcomes. This group was characterized by higher mortality rate and neuropsychiatric/vascular/skin organ damage in spite of comparable frequencies of severe cumulative lupus manifestations. We also identified that overall death in cSLE patients was an early event mainly attributed to infection associated with disease activity.
