Proteome Signature for Differential Diagnosis of Patients with Bilateral Lung Infiltrates

BackgroundThe differential diagnosis of bilateral lung infiltrates and prognosis prediction can be challenging for clinicians in the intensive care unit (ICU). We analyzed the proteome from bronchoalveolar lavage fluid (BALF) and determine their usefulness for evaluating the infectious causes and mortality associated with bilateral lung infiltrates.MethodsIn the ICU cohort, 136 patients with bilateral infiltrate on chest radiographs were selected, and bronchoscopy with bronchoalveolar lavage (BAL) was performed. Proteomics profiling of the exosomes in the BALF (n=20) was conducted to identify candidate protein biomarkers potentially associated with infection or mortality. The BAL samples (n=116) were used to measure the candidate biomarker levels.ResultsThe candidate biomarkers, CD20, CLIC4, SCFD1, and TAP1, were selected for the differential diagnosis of infection or mortality. The levels of CD20 were significantly elevated in patients with non-infectious causes compared to those with infectious causes (248.6±154.5versus177.6±150.9 ng·mL−1, p=0.014). The levels of CLIC4, SCFD1, and TAP1 did not differ between the two groups. As per the receiver operating characteristic analysis, CD20 was a significant predictor of non-infectious causes (area under curve, 0.668; 95% CI, 0.567–0.769; p=0.002; cut off value, 167.6 ng·mL−1; sensitivity, 74.1%; specificity, 63.2%). There were no significant differences in the concentrations of the biomarkers between survivors and non-survivors.ConclusionsOur results suggested that CD20 levels in BALF might be a useful biomarker for differentiating non-infectious and infectious diseases in patients with bilateral lung infiltrates.

Beyond Infection: Mortality and End-of-Life Care Associated with Infectious Disease Consultation in an Academic Health System.

Infectious diseases (ID) physicians are increasingly faced with the challenge of caring for patients with terminal illnesses or incurable infections. This was a retrospective cohort of all patients with an ID consult within an academic health system 1/1/2014 - 12/31/2023, including community, general, and transplant ID consult services. There were 60,820 inpatient ID consults (17,235 community, 29,999 general, and 13,586 transplant) involving 37,848 unique patients. The number of consults increased by 94% and the rate rose from 5.0 to 9.9 consults per 100 inpatients (p<0.001). In total, 7.5% of patients receiving an ID consult died during admission, and 1,006 (2.6%) of patients were discharged to hospice. In-hospital mortality was 5.2% for community ID, 7.8% for general ID, and 10.7% for transplant ID patients (p<0.001). Six-month mortality was 9% for all non-obstetric admissions, , vs. 19% for community ID, 20.9% for general ID, and 22.3% for transplant ID.In total 2,866 (7.6%) of all patients receiving ID consultation also received palliative care consultation during the same hospitalization. The index ID consult preceded any palliative consult in the majority (69.5%) of cases. 16.3% of patients had a do-not-resuscitate order during the index hospitalization. 12.2% of all patients with a do-not-resuscitate order had this placed on the same day as the ID consult. Patients receiving ID consultation were increasingly complex and more likely to die soon after consultation. These results provide a framework for ID clinicians to consider their role in end-of-life care.

Preventive dental care reduces risk of cardiovascular disease and pneumonia in hemodialysis population: a nationwide claims database analysis

This study aims to investigate the impact of dental care utilization status on the occurrence of fatal complications such as cerebral/cardiovascular disease (CVD) and infectious diseases in patients with end-stage renal disease (ESRD) undergoing hemodialysis. This retrospective cohort study was performed using the Japanese claims database and included patients who first underwent hemodialysis between April 2014 and September 2020. The exposure variable of interest was the pattern of dental utilization, which was categorized into three groups, “dental treatment group”, “preventive dental care group”, and “no-dental visit group”. The primary outcomes were the time interval until a composite end point of first major cardiovascular event (acute myocardial infarction, heart failure, or cerebral infarction) of infectious disease (pneumonia and sepsis). The secondary outcomes were the time interval until the incidence of each component of primary outcomes. Survival analyses, including log-rank tests and Cox proportional hazards regression analyses, were performed. Among the 10,873 patients who underwent the first dialysis treatment, 6152 were assigned to the no-dental visit group, 2221 to the dental treatment group, and 2500 to the preventive dental care group. The preventive dental care group had significantly lower hazard ratios (HRs) of the incidence of CVD (adjusted hazard ratio [aHR]: 0.86, 95% confidence interval [CI]: 0.77–0.96) and infectious diseases (aHR: 0.86, 95% CI: 0.76–0.97). As for pneumonia, preventive dental care and dental treatment groups had significantly lower HRs (aHR: 0.74 and 0.80, 95% CI: 0.61–0.88, 0.66–0.96) than the no-dental visit group. This study demonstrated that dental visits for preventive dental care were associated with a significant risk reduction in CVD and infectious complications in patients with ESRD undergoing hemodialysis.

New derivatives of quinazolinone as an object in the search for substances that exhibit a multi-target effect

Due to the rapid growth in the number of patients with diabetes in a complicated epidemiological picture, the question of the possibility of exposure of a substance to several targets becomes more important. It is noted that the most common infectious diseases in patients with diabetes mellitus are infections of the respiratory and urinary tract, skin and soft tissues, diabetic foot ulcers, otitis media and periodontal infections. Antimicrobial agents can have both direct and indirect hypoglycemic effects. Quinazolinones belonging to the group of heterocyclic derivatives exhibit a wide range of pharmacological activity. The use of the PASS program for the purpose of computer prediction of pharmacological activity showed a high probability of the hypoglycemic effect of new derivatives. The obtained results motivated the authors to search for the relationship between antimicrobial action and hypoglycemic effect within the general direction of studying the multi-targeting of drug ligands. Analysis of the literature data, as well as own studies of new quinazolinone derivative pharmacological activity make it possible to divide all ligands into functional groups that cause additional binding to the target molecule. The quinazolinone fragment, characterized by the uniqueness of its structure, can be reasonably attributed to multi-target ligands. The triazole cycle and the sulfonamide group can also purposefully bind to the target molecule. A carbamide residue, a fragment of sulfonylurea and an acetamide group, depending on the structure of the substance they are part of, can function both as a specific ligand and as a functional group involved in the stabilization of the intermediate transition state. The results obtained by the authors, as well as other researchers, allow us to formulate an assumption about the relationship between the mechanisms of antimicrobial and hyperglycemic activity.

Application of metagenomic next-generation sequencing in the clinical diagnosis of infectious diseases after allo-HSCT: a single-center analysis

BackgroundWe investigated the value of metagenomic next-generation sequencing (mNGS) in diagnosing infectious diseases in patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT).MethodsFifty-four patients who had fever following allo-HSCT from October 2019 to February 2022 were enrolled. Conventional microbiological tests (CMTs) and mNGS, along with imaging and clinical manifestations, were used to diagnose infection following allo-HSCT. The clinical diagnostic value of mNGS was evaluated.ResultsA total of 61 mNGS tests were performed, resulting in the diagnosis of 46 cases of infectious diseases. Among these cases, there were 22 cases of viral infection, 13 cases of fungal infection, and 11 cases of bacterial infection. Moreover, 27 cases (58.7%) were classified as bloodstream infections, 15 (32.6%) as respiratory infections, 2 (4.3%) as digestive system infections, and 2 (4.3%) as central nervous system infections. Additionally, there were 8 cases with non-infectious diseases (8/54, 14.81%), including 2 cases of interstitial pneumonia, 2 cases of bronchiolitis obliterans, 2 cases of engraftment syndrome, and 2 cases of acute graft-versus-host disease. The positive detection rates of mNGS and CMT were 88.9% and 33.3%, respectively, with significant differences (P < 0.001). The sensitivity of mNGS was 97.82%, the specificity was 25%, the positive predictive value was 93.75%, and the negative predictive value was 50%. Following treatment, 51 patients showed improvement, and 3 cases succumbed to multidrug-resistant bacterial infections.ConclusionsmNGS plays an important role in the early clinical diagnosis of infectious diseases after allo-HSCT, which is not affected by immunosuppression status, empiric antibiotic therapy, and multi-microbial mixed infection.

Live vaccinations in dermatology for immunosuppressed patients: a narrative review.

Given the higher susceptibility to infectious disease in patients receiving immunosuppressive therapies for inflammatory dermatologic conditions, immunization is important in this population. While live vaccines protect against life-threatening diseases, they can be harmful in immunosuppressed patients given the risk of replication of the attenuated pathogen and adverse reactions. The utilization of live vaccines in immunosuppressed patients depends on multiple factors such as the vaccine and therapy regimen. To provide an overview of evidence-based recommendations for the use of live vaccines in patients receiving immunosuppressive therapies for dermatological conditions. A literature search of the PubMed database was performed using keywords live vaccine, live-attenuated vaccine, dermatology, immunosuppressed, and immunocompromised, and specific immunosuppressive therapies: corticosteroids, glucocorticoids, methotrexate, azathioprine, cyclosporine, mycophenolate mofetil, biologics. Relevant articles written in English were included. Using these keywords, 125 articles were reviewed, of which 28 were ultimately selected. Recommendations for live vaccines can be determined on a case-by-case basis. Measles, mumps, rubella, varicella (MMRV) vaccines may be safely administered to patients on low-dose immunosuppressive agents while the yellow fever vaccine is typically contraindicated. It may be safe to administer live MMRV boosters to children on immunosuppressive therapies and the live herpes zoster vaccine to patients on biologics. Given poor adherence to immunization guidelines in immunosuppressed patients, dermatologists have a critical role in educating patients and general practitioners regarding live vaccines. By reviewing a patient's vaccination history and following immunization guidelines prior to initiating immunosuppressive therapies, physicians can mitigate morbidity and mortality from vaccine-preventable diseases.

Investigating and Summarizing Information Resources Related to the Clinical Presentation and Diagnosis of Cutaneous Manifestations of Infectious Diseases in Patients With Skin of Color.

Patients with skin of color (SOC) present diseases differently in many circumstances, yet there is a lack of information regarding the presentation and diagnosis of cutaneous manifestations in such patients experiencing infectious diseases. Therefore, we conducted a scoping review to investigate and summarize information pertaining to the clinical presentation and diagnosis of cutaneous manifestations of infectious diseases in patients with SOC focusing on the following viral, bacterial, toxin-mediated, and infestation diseases and fungal infections: human immunodeficiency virus, shingles, impetigo, scarlet fever, Lyme disease, toxic shock syndrome, scabies, rickettsioses, and cutaneous fungal infections. This scoping review identified literature gaps regarding cutaneous manifestations of infectious diseases in patients with SOC such as a lack of visual examples and more precise descriptions of common infectious diseases. The lack of better-quality literature and educational resources describing cutaneous manifestations of infectious diseases in patients with SOC may contribute to care barriers; therefore, more research and collaboration are needed in the specialties of both infectious diseases and dermatology.

Survey of Japanese nephrologists' use of clinical practice guidelines for rapidly progressive glomerulonephritis.

The guidelines in Japan for the treatment of rapidly progressive glomerulonephritis (RPGN) have been revised; the latest update was released in 2020. We investigated the actual usage of the new guidelines in Japan. We distributed a survey electronically to board-certified nephrologists throughout Japan from December 15, 2021 to January 31, 2022. The survey focused on anti-neutrophil cytoplasmic antibody (ANCA)-associated RPGN and anti-glomerular basement membrane (GBM)-antibody RPGN, plus the treatment strategies and infection-prevention measures used. The survey was completed by 155 certified nephrologists from medical facilities across Japan. Their responses regarding treatment procedures revealed that ANCA-associated RPGN was treated with immunosuppressants and/or biologics by 58.1% of the survey respondents, and with plasma exchange (PE) in combination with corticosteroids by 21.3%. Regarding anti-GBM-antibody RPGN, 78.1% of the respondents used corticosteroids in combination with PE (63.2%), cyclophosphamide (CY) (23.9%), or rituximab (RTX) (8.4%), suggesting a discrepancy between clinical practice and the actual use of the guidelines. Trimethoprim-sulfamethoxazole was prescribed as prophylaxis by 94.8% of the respondents, reflecting the widespread recognition of the need to prevent infectious disease in patients with RPGN. The survey responses revealed how Japan's new RPGN guidelines are used in actual clinical practice. Our findings will contribute to the guidelines' dissemination and implementation.

Clinical application of amplification-based versus amplification-free metagenomic next-generation sequencing test in infectious diseases.

Recently, metagenomic next-generation sequencing (mNGS) has been used in the diagnosis of infectious diseases (IDs) as an emerging and powerful tool. However, whether the complicated methodological variation in mNGS detections makes a difference in their clinical performance is still unknown. Here we conducted a method study on the clinical application of mNGS tests in the DNA detection of IDs. We analyzed the effect of several potential factors in the whole process of mNGS for DNA detection on microorganism identification in 98 samples of suspected ID patients by amplification-based mNGS. The amplification-based and amplification-free mNGS tests were successfully performed in 41 samples. Then we compared the clinical application of the two mNGS methods in the DNA detection of IDs. We found that a higher concentration of extracted nucleic acid was more conducive to detecting microorganisms. Other potential factors, such as read depth and proportion of human reads, might not be attributed to microorganism identification. The concordance rate of amplification-based and amplification-free mNGS results was 80.5% (33/41) in the patients with suspected IDs. Amplification-based mNGS showed approximately 16.7% higher sensitivity than amplification-free mNGS. However, 4 cases with causative pathogens only detected by amplification-based mNGS were finally proved false-positive. In addition, empirical antibiotic treatments were adjusted in 18 patients following mNGS testing with unexpected pathogens. Amplification-based and amplification-free mNGS tests showed their specific advantages and disadvantages in the diagnosis of IDs. The clinical application of mNGS still needs more exploration from a methodological perspective. With advanced technology and standardized procedure, mNGS will play a promising role in the diagnosis of IDs and help guide the use of antibiotics.

The case was identified via pathogen-targeted next-generation sequencing (ptNGS).ConclusionThis is the first report of disseminated M. thermoresistibile infection presented with lymphadenectasis in an AIDS patient. Prompt diagnosis and antimicrobial treatment are crucial.

Screening for latent infectious disease in patients with alopecia areata before initiating JAK inhibitors therapy: a single-center real-world retrospective study.

Although there is growing evidence supporting the effectiveness of Janus kinase (JAK) inhibitors in treating alopecia areata, the high rate of recurrence following drug discontinuation has led to prolonged treatment courses and raised concerns about long-term safety. In clinical practice, caution should be exercised while using JAK inhibitors for various indications, and a comprehensive pre-treatment screening. This study presents an analysis of screening data collected from real-world settings before the initiation of Janus kinase inhibitors in patients with alopecia areata. Investigators collected retrospective medical data characterizing patients' screening data. Data on demographic and clinical data, including age, sex, disease duration, severity of alopecia tool scale, history of prior treatment, and treatment regimen were recorded. In this cohort (N = 218), JAK inhibitors were initiated for 163 of 218 (74.8%) alopecia areata patients. The numbers of patients positive for antinuclear antibodies, hepatitis B surface antigen, hepatitis C virus antibodies, human immunodeficiency virus antibody, treponema pallidum hemagglutination assay, and thyroid-stimulating hormone were 32 (32/176), 10(10/218), 0 (0/218), 0 (0/218), 3 (3/218) and 9 (9/176), respectively. The number of patients with T-cell spot positive or imaging of the chest indicating tuberculosis was 37 (37/218). Our data provide additional information on the safety profile of JAK inhibitors in patients with alopecia areata. As such, it is necessary and crucial to screen for JAK inhibitors before it is used, particularly for individuals with a high risk of tuberculosis, hepatitis B, and other infections.

Effects of Antihypertensive Agents on the Clinical Outcome of Hospitalized COVID-19 Patients Concomitant with Hypertension: A Systematic Review and Meta-Analysis

BackgroundGiven the ongoing COVID-19 pandemic, it is crucial to prioritize the management of underlying diseases in infected patients, with hypertension being one of the most common conditions. However, there lies a complicated correlation between antihypertensive agents and COVID-19 infection. ObjectivesThis study is to systematically evaluate the impact of continuing or discontinuing antihypertensive agents on mortality and infection severity in hospitalized patients with both hypertension and COVID-19. MethodsA systematic electronic search was conducted on PubMed, Embase, Cochrane, Web of Science, and ClinicalTrials.gov to identify relevant clinical trials published between 1948 and September 2022. Two independent reviewers assessed the quality of the included studies and extracted relevant data. The primary outcome of interest was the relationship between in-hospital mortality and administration of antihypertensive agents. ResultsThe meta-analysis revealed that continuous administration of antihypertensive agents, compared with discontinuation, significantly reduced in-hospital mortality among hypertension patients with COVID-19 infection [OR=0.49, 95 %CI (0.38, 0.65), p < 0.001, I2=65.3 %]. Specifically, patients receiving ACEI/ARB type agents had even lower mortality rates. Meta-regression analyses were conducted to examine the impact of publication date, sample size, study design, and mean age of the patients, and the results showed that the number of participants in the included studies was the primary source of heterogeneity (p = 0.032). The findings indicated a clear association between the use of antihypertensive agents and reduced mortality in these patients. Conclusionnder the current circumstance of the sustained COVID-19 pandemic, it is recommended to continue the use of antihypertensive agents for patients with hypertension during COVID-19 infection, as it can help reduce the risk of mortality.

Implementing a peer-supported, integrated strategy for substance use disorder care in an outpatient infectious disease clinic is associated with improved patient outcomes

Substance use disorder (SUD) and infectious disease (ID) care integration may lead to improvements in SUD and ID outcomes. We assessed implementation of integrating peer-supported SUD care in an outpatient ID setting. In this implementation study, we describe REcovery in Specialty care Through medication and OutREach (RESTORE), a low-threshold SUD program implemented in a Baltimore outpatient ID clinic. Key program components were clinician training and support in SUD care, prescription of SUD treatment medications, and peer-based psychosocial support provided by peer recovery specialists. We assessed clinician adoption of RESTORE and compared patient outcomes from baseline to 6 months. Between January 2019 and January 2022, the number of ID clinicians (N=61) who prescribed buprenorphine increased eightfold from 3 (5%) to 24 (39%). Of 258 ID patients referred to RESTORE, 182 (71%) engaged, 137 consented to study participation. Mean age in the study sample was 52.1 (SD=10.4), 63% were male, 84% were Black/African-American. Among 127 (93%) who completed 6-month follow-up, fewer participants reported illicit/non-prescribed opioid use in the past 30 days at follow-up (32%) compared to baseline (52%; p<0.001). Similar reductions were noted for cocaine use (47% to 34%; p=0.006), emergency department visits (23% to 9%; p=0.002), and inpatient hospitalizations (15% to 7%; p=0.025). SUD care integration into an outpatient ID care setting using a peer-supported implementation strategy was adopted by clinicians and improved clinical outcomes for patients. This strategy is a promising approach to treating people with infectious diseases and SUD.

Infectious complications in patients with inflammatory bowel disease in Asia: the results of a multinational web-based survey in the 8th Asian Organization for Crohn's and Colitis meeting.

Infectious complications are major concerns when treating patients with inflammatory bowel disease (IBD). This study evaluated clinical differences across countries/regions in the management of infectious diseases in patients with IBD. A multinational online questionnaire survey was administered to participants at the 8th meeting of the Asian Organization for Crohn's and Colitis. The questionnaire included questions regarding surveillance, diagnosis, management, and prevention of infection in patients with IBD. A total of 384 physicians responded to the questionnaire. The majority of Korean (n=70, 63.6%) and Chinese (n=51, 51.5%) physicians preferred vancomycin to metronidazole in the treatment of Clostridium difficile infection, whereas more than half of the Japanese physicians (n=62, 66.7%) preferred metronidazole. Physicians in Korea (n=88, 80.0%) and China (n=46, 46.5%) preferred a 3-month course of isoniazid and rifampin to treat latent tuberculosis infection, whereas most physicians in Japan (n=71, 76.3%) favored a 9-month course of isoniazid. Most Korean physicians (n=89, 80.9%) recommended hepatitis B virus (HBV) vaccination in patients lacking HBV surface antigen, whereas more than half of Japanese physicians (n=53, 57.0%) did not consider vaccination. Differences in the diagnosis, prevention, and management of infections in patients with IBD across countries/regions reflect different prevalence rates of infectious diseases. This survey may broaden understanding of the real-world clinical settings across Asian countries/regions and provide information for establishing practical guidelines to manage patients with IBD.

Autoimmune skin disorders and SARS-CoV-2 vaccination - a meta-analysis.

The coronavirus SARS-CoV-2, which is the cause of COVID-19 disease in infected patients, has led to an ongoing worldwide pandemic. Although SARS-CoV-2 vaccination had a dramatic positive effect on the course of COVID-19, there has been increasing evidence of adverse effects after SARS-CoV-2 vaccination. This meta-analysis highlights the association between SARS-CoV-2 vaccination and de novo induction or aggravation of inflammatory and autoimmune skin diseases. A systematic meta-analysis of the literature on new onset or worsening of inflammatory and autoimmune diseases after SARS-CoV-2 vaccination was performed according to the PRISMA guidelines. The search strategy included following terms: "COVID-19/SARS-CoV-2 vaccine bullous pemphigoid/pemphigus vulgaris/systemic lupus erythematosus/dermatomyositis/lichen planus/leukocytoclastic vasculitis." Moreover, we describe representative cases from our dermatology department. The database-search in MEDLINE identified 31 publications on bullous pemphigoid, 24 on pemphigus vulgaris, 65 on systemic lupus erythematosus, nine on dermatomyositis, 30 on lichen planus, and 37 on leukocytoclastic vasculitis until June 30th, 2022. Severity and response to treatment varied among the described cases. Our meta-analysis highlights a link between SARS-CoV-2 vaccination and new onset or worsening of inflammatory and autoimmune skin diseases. Moreover, the extent of disease exacerbation has been exemplified by cases from our dermatological department.

Increased thoracic fluid content is associated with higher risk for pneumonia in patients undergoing maintenance hemodialysis

Background Pneumonia is the most common infectious disease in patients undergoing maintenance hemodialysis (MHD). The aim of this study is to determine the possible predictive value of thoracic fluid content (TFC) for pneumonia in this population. Method Clinical data were recorded for 1412 MHD patients who were hospitalized for certain comorbidities or complications. Each patient underwent an impedance cardiography (ICG) examination before next dialysis session after admission. Patients were divided into Having-, Will-have-, and Non-pneumonia groups based on whether they had pneumonia at the time of ICG examination after the admission and within five months after the examination. Hemodynamic parameters and other clinical data were compared and analyzed. Results Patients who were going to develop pneumonia were older, and had a higher proportion of diabetes, poorer nutritional status, a higher level of inflammatory, poorer cardiac function, and more fluid volume load than those who did not develop pneumonia. Multivariate binary logistic analysis revealed that for each 1/KΩ increase in TFC and 1 increase in neutrophil-to-lymphocyte ratio (NLR), the risk of the development of pneumonia increased by 3.1% (p ˂ 0.01) and 7.2% (p = 0.035), respectively, whereas for each 1 g/L increase in hemoglobin and 1 g/L increase in serum albumin, the risk of the development of pneumonia decreased by 1.3% (p = 0.034) and 5% (p = 0.048), respectively. Conclusions TFC, NLR, hemoglobin, and serum albumin were independent risk factors for the development of pneumonia in MHD patients. Given the advantages of ICG, TFC can be used clinically as a helpful predictor of pneumonia in MHD patients.

JAK inhibitors: high risk of infectious disease in patients with RA

JAK inhibitors: high risk of infectious disease in patients with RA

A survey of systemic lupus erythematosus patients' attitudes toward influenza and pneumococcal vaccination in Southwest China.

Vaccination is the most effective measure for prevention against infectious diseases in patients with systemic lupus erythematosus (SLE). Therefore, it is important to know SLE patients' attitudes toward influenza and pneumococcal vaccination. This study aimed to investigate the attitude toward influenza and pneumococcal vaccination among SLE patients in Southwest China and its influencing factors. A web-based questionnaire was conducted to collect data regarding SLE patients' demographics, history of infections, medications, comorbidities, attitudes toward infection and vaccination, rates of influenza and pneumococcal vaccination, and role of health professionals in promoting vaccination. Univariate and multivariate logistic regression analyses were conducted to assess the vaccination willingness-associated factors. A total of 251 patients participated in the survey and 240 questionnaires were completed and statistically analyzed. The influenza and pneumococcal vaccination rates were 8.3 and 1.7%, respectively. The top three reasons for non-vaccination were worrying about the SLE exacerbation or flare resulting from the vaccine or its adjuvants, being concerned about adverse events, and the lack of awareness of vaccine availability. More than half of the participants were willing to be vaccinated against influenza (56.2%) and pneumococcus (52.9%). Factors associated to the willingness to receive the influenza vaccine and pneumococcal vaccine were being afraid of infection, believing in the efficacy of influenza vaccination, lower family income, less perceived care from family members, perceived susceptibility to pneumococcal infection, and perceiving influenza and pneumococcal vaccination as beneficial for health. The influenza and pneumococcal vaccination rates are low among SLE patients in Southwest China. The positive perspective of vaccination on health represented the most impacting factor on their willingness to undergo influenza and pneumococcal vaccination. Non-vaccinated patients were mainly concerned about exacerbation of the disease or adverse events caused by vaccines. It is important to improve the compliance with the guideline-recommended roles of health professionals and to promote the collaboration between rheumatology and primary care teams.
