RESUMO
OBJECTIVE: To investigate the risk of DM and evaluate the impact of SLE therapies on the risk of developing DM in patients with SLE. METHODS: Electronic database searches of PubMed, Embase, Cochrane Library and Web of Science were performed from inception to February 2023. Cohort and cross-sectional studies that analysed the risk of DM in patients with SLE were included. The associations between diabetes and antirheumatic agents, such as antimalarials and glucocorticoids, were analysed in cohort studies. Data were pooled using fixed- or random-effects meta-analysis to estimate pooled odd ratios (OR), relative risks (RR) and 95% confidence intervals (CIs). This study was registered with PROSPERO (CRD42023402774). RESULTS: A total of 37 studies (23 cross-sectional and 14 cohort studies) involving 266 537 patients with SLE were included. The pooled analyses from cross-sectional studies and cohort studies did not show an increased risk of DM in SLE patients (OR = 1.05, 95% CI 0.87-1.27; P = 0.63 and RR = 1.32, 95% CI 0.93-1.87; P = 0.12, respectively). However, several cohort studies consistently demonstrated a reduced risk of diabetes with antimalarials, while glucocorticoid use has been associated with an increased risk of developing diabetes. Age, sex, hypertension and immunosuppressants have not been identified as risk factors for DM in SLE patients. CONCLUSION: Although there was no increased risk of DM in patients with SLE compared with controls, HCQ users or adherents had a decreased risk, whereas glucocorticoid users had an increased risk.

BACKGROUND: Anti-C20 monoclonal antibodies (MAb), such as rituximab, are commonly used for the treatment of patients with severe or refractory systemic lupus erythematosus (SLE) but clinical outcomes are highly variable. We aimed to provide an update of a systematic review of predictive and prognostic factors of anti-CD20 MAb treatment in SLE. METHODS: A systematic literature search was undertaken to identify predictive and prognostic factors of clinical response following treatment with anti-CD20 therapies in SLE patients. Studies examining rituximab published prior to 2015 were excluded. Risk of bias was assessed for randomized controlled trials (RCTs) using the Cochrane Collaboration (RoB2) tool for RCTs and the Quality In Prognosis Studies Tool (QUIPS) for cohort studies. A narrative synthesis of the evidence was undertaken and quality of evidence (QoE) was assessed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: From 850 studies identified, 17 studies met the inclusion criteria. A further 8 studies were identified and included through search updates. There were two post-hoc analyses of RCTs of rituximab, one RCT of ocrelizumab and one of obinutuzumab; and 16 cohort studies examining rituximab treatment. The overall QoE was low or very low. There was wide heterogeneity in definitions of clinical disease activity and outcome measures, non-standardized laboratory cut-offs, failure to account for confounders and multiple subgroup analyses of differing outcomes. B cell depletion as well as novel biomarkers, such as S100 proteins, FCGR genotype, anti-vimentin and anti-drug antibodies showed some evidence of prognostic value but QoE was limited due to moderate to high risk of bias, early phase of investigation and imprecision of results. CONCLUSION: There has been no validation of previously identified prognostic factors to guide outcome in anti-CD20 treated lupus patients. Hypothesis-driven studies of several novel markers however, demonstrate prognostic value and require replication and validation to support their use in routine clinical practice.

OBJECTIVE: To describe the results from the Global Burden Disease (GBD) study 2019 on the burden of other musculoskeletal (MSK) disorders in Latin America and the Caribbean (LAC). METHODS: In this cross-sectional study, we analyzed data from all LAC region in the GBD study from 1990 to 2019. Other MSK (other than rheumatoid arthritis, osteoarthritis, gout, low back pain, and neck pain) burden was measured as prevalence, mortality, years lived with disability (YLD), and disability-adjusted life (DALY), by year, sex, and country. We show the counts, rates, and 95% uncertainty intervals (95% UI). Joinpoint regression analysis was used to estimate the average annual percentage change (AAPC) from 1990 to 2019. A correlational analysis between the burden parameters and sociodemographic index (SDI) was performed. RESULTS: In 2019, there were 52.0 million (95% UI, 44.8-60.1 million) individuals with other MSK disorders in LAC. The age-standardized mortality rate in 2019 was 1.2 (95% UI, 0.8-1.6) per 100,000 inhabitants. The AAPC was estimated as 0.1% (95% confidence interval [CI], 0.1-0.2) and 0.2% (95% CI, 0.1-0.3) for prevalence and mortality rates, respectively. The age-standardized DALY rate was 685.4 (95% UI, 483.6-483.6) per 100,000 inhabitants, representing an AAPC of 0.2% (95% CI, 0.1-0.3). The burden was larger in women and the elderly. The SDI was positively correlated with the prevalence of YLD in 2019. CONCLUSIONS: LAC region has experienced a significant burden of other MSK disorders over the last three decades. To challenge this growing burden, population-based strategies designed to reduce the burden of other MSK and strengthen health systems to contribute effective and cost-efficient care are necessary.

OBJECTIVE: This study aimed to describe the disease burden and trends of musculoskeletal (MSK) disorders in Mexico from 1990 to 2019. METHOD: A cross-sectional study using systematic analysis from the Global Burden of Disease Study 2019 (GBD study 2019) was performed to analyze data on MSK disorders and estimate crude and age-standardized rates per 100,000 population concerning disease prevalence, incidence, mortality, disability-adjusted life-years (DALY), and years lived with disability (YLD). The average annual percentage change (AAPC) was calculated using the joinpoint regression. RESULTS: In 2019, there were 4.8 million (95% UI 4.3, 5.4) new cases and 3,312 (95% UI 2201, 4,790) deaths attributable to MSK disorders. In 2019, MSK disorders ranked first, increasing from 1990 (second rank) for the YLD in Mexico. Subnational variations were identified, with the state of Oaxaca having the highest age-standardized incidence rate (ASIR) per 100,000 population in 2019. Joinpoint analysis revealed a significant increase in prevalence in Mexico from 1990 to 2019 (AAPC: 0.14%; 95%CI 0.09-0.19), incidence (AAPC: 0.05%; 95%CI 0.03-0.07), DALY (AAPC: 0.13%; 95%CI 0.04-0.22), and YLD (AAPC: 0.13%; 95%CI 0.02-0.24). Among the risk factors, occupational ergonomic factors and high body mass index (BMI) had the largest influence on MSK disorders. CONCLUSIONS: In Mexico, we observed an increase the national burden of MSK disorders from 1990 to 2019. Specific determinants, such as occupational ergonomic factors and high BMI, contribute to the MSK disorder burden. The burden of MSK disorders requires an improved and prompt assessment to plan valuable diagnostic and management approaches. Key Points ⢠In Mexico, the burden of musculoskeletal (MSK) disorders increased from 1990 to 2019. ⢠Specific risk factors, such as occupational ergonomic factors and high body mass index, contribute to the MSK disorder burden.

Antiphospholipid antibody syndrome (usually named antiphospholipid syndrome, APS) is an autoimmune disorder seen mainly in young people. Clinically, APS is described by pregnancy complications and/or a hypercoagulable state, including the venous or arterial vasculature, and strongly related to antiphospholipid antibodies. Although several cardiac manifestations have been involved with APS, and accelerated atherosclerosis is present in this condition, little is known about cardiovascular (CV) risk and the relation between APS. Several studies have used imaging markers to associate them with the main clinical features of patients with APS and the probability of having subclinical atherosclerosis. However, it has not yet been established which markers are most related to the risk of developing CV diseases (CVD) in these patients. In this narrative review, we focus on non-invasive imaging markers that can predict CVD, including carotid intima-media thickness and carotid plaques assessed by carotid ultrasonography or coronary artery calcium score, which usually by computed tomography. We also examine the evidence about vascular function markers used in APS, such as arterial flow-mediated brachial dilation and artery stiffness measured by the velocity of the pulse wave. We present the current status of non-invasive imaging markers, which suggest the existence of subclinical atherosclerosis in patients with APS. However, new prospective research is required to identify the predictive value of these findings and their modification by current treatments for APS.

BACKGROUND: Low disease activity state (LDAS) has been linked to a significant reduction in flares and damage accrual in patients with systemic lupus erythematosus (SLE); however, the effect of LDAS on the risk of vertebral fractures (VFs) in subjects with SLE is unknown, considering that low bone mineral density (BMD) and VF are frequent in SLE. OBJECTIVE: to evaluate whether achieving LDAS ≥50% of the observation time prevents new VF and BMD changes in Mestizo women. METHODS: We carried out a longitudinal, observational, and retrospective study. Mestizo women with SLE were included for a median of an 8-year follow-up. LDAS was described as Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score ≤4, prednisone ≤7.5 mg/day, and stable immunosuppressive therapies. BMD measurements and lateral thoracic and lumbar radiographs for a semiquantitative analysis for VF were assessed at baseline and during the follow-up. Uni- and multivariable interval-censored survival regression models were carried out. RESULTS: We included 110 patients: 35 (31.8%) had new VF. A total of 56 patients (50.1%) achieved LDAS ≥50% of the time during the follow-up and achieved a significantly lesser risk of incident VF (HR = 0.16; 95% CI, 0.06-0.49). After adjusting by age, BMI, menopause, prevalent VF, baseline BMD, cumulative glucocorticoid use, and anti-osteoporotic therapy, LDAS-50 was significantly related to a decrease in the risk of a new VF (HR = 0.39; 95% CI, 0.16-0.98). There was no association between LDAS and BMD measurement changes. When only patients on LDAS but not in remission (n = 43) were evaluated for the risk of incident VF, both uni- and multivariate analyses were significant (HR = 0.12; 95 CI, 0.04-47; p = 0.001, and HR = 0.26; 95% CI, 0.7-0.88; p = 0.03). CONCLUSIONS: LDAS ≥50% of the time was significantly associated with a diminished risk of new VF in Mestizo women with SLE, even in patients not in remission. However, LDAS did not help modify BMD changes over time.

The Systemic Lupus International Clinics (SLICC)-Frailty Index (FI) is associated with adverse outcomes in systemic lupus erythematosus (SLE). However, to our knowledge, its association with bone mineral density (BMD) and vertebral fractures (VF), has not been investigated using a standardized methods. Our aim was to evaluate the relationship between frailty assessed by SLICC-FI, and BMD and VF in Mestizo women with SLE. Adult women were included in this cross-sectional study. Information concerning the risk factors for VF and BMD in the lumbar spine and total hip was acquired. SLICC-FI was assessed at baseline. A semi-quantitative method was utilized to evaluate the prevalence of VF on lateral thoracolumbar radiographs. Univariate and multivariate regression analyses were performed adjusting for age, body mass index (BMI), SLE duration, cumulative glucocorticoid dose, bisphosphonate use, and BMD measurements. We included 202 women with SLE (mean age [SD] = 43.3 [13.6] years). The mean (SD) SLICC-FI value was 0.14 (0.09). Eleven (5.4%) patients were categorized as robust, 62 (30.7%) as relatively less fit, 84 (41.6%) as least fit, and 45 (22.3%) as frail. Both univariate and multivariate models showed associations between frailty (defined as SLICC-FI > 0.21) and prevalent VF in the entire population (OR 5.76, 95% CI 2.53-13.12; P < 0.001) and in the premenopausal group (OR 4.29, 95% CI; P = 0.047). We also found an association between the SLICC-FI and low BMD. In conclusion, frailty assessed by SLICC-FI might be associated with VF and low BMD in mestizo females with SLE.

The study aimed to analyze the influence of the COVID-19 pandemic on mortality rates in patients with systemic autoimmune rheumatic diseases (SARD) in Mexico. We selected SARD-related deaths using National Open Data and Information from the Ministry of Health, Mexico, and ICD-10 codes. We assessed the observed compared to the predicted mortality values for 2020 and 2021, employing trends from 2010 to 2019 with joinpoint and prediction modelling analyses. Among 12,742 deaths due to SARD between 2010 and 2021, the age-standardized mortality rate (ASMR) increased significantly between 2010 and 2019 (pre-pandemic) (annual percentage change [APC] 1.1%; 95% CI 0.2-2.1), followed by a non-significant decrease during the pandemic period (APC 13.9%; 95% CI 13.9-5.3). In addition, the observed ASMR of 1.19 for 2020 for SARD and of 1.14 for 2021 were lower than the predicted values of 1.25 (95% CI 1.22-1.28) for 2020 and 1.25 (95% CI 1.20-1.30) for 2021. Similar findings were identified for specific SARD, mainly systemic lupus erythematosus (SLE), or by sex or age group. Interestingly, the observed mortality rates for SLE in the Southern region of 1.00 in 2020 and 1.01 in 2021 were both significantly greater than the predicted values of 0.71 (95% CI 0.65-0.77) in 2020 and 0.71 (95% CI 0.63-0.79). In Mexico, the observed SARD mortality rates were not higher than the expected values during the pandemic, except for SLE in the Southern region. No differences by sex or age group were identified.

The aims of this study were in systemic lupus erythematosus (SLE) patients: 1) to compare the metabolomic profile of insulin resistance (IR) with controls and 2) to correlate the metabolomic profile with other IR surrogates and SLE disease variables and vitamin levels. In this cross-sectional study, serum samples were collected from women with SLE (n=64) and gender- and age-matched controls (n=71), which were not diabetic. Serum metabolomic profiling was performed using UPLC-MS-MS (Quantse score). HOMA and QUICKI were carried out. Serum 25(OH)D concentrations were measured by chemiluminescent immunoassay. In women with SLE, the metabolomic Quantose score significantly correlated with HOMA-IR, HOMA2-IR, and QUICKI. Although concentrations of IR metabolites were not different between SLE patients and controls, fasting plasma insulin levels were higher and insulin sensitivity lower in SLE women. Interestingly, the Quantose IR score was significantly correlated with complement C3 levels (r=0.7; p=0.001). 25 (OH)D did not correlate with any metabolite or the Quantose IR index. Quantose IR may be a useful tool for IR assessment. There was a possible correlation between the metabolomic profile and complement C3 levels. The implementation of this metabolic strategy may help develop biochemical insight into metabolic disorders in SLE.

SLE increases disease burden in those affected with it, and that is particularly the case in low- and middle-income countries. The 2019 Addressing Lupus Pillar of Health Advancement project is a multiphase initiative whose objective is to recognize, hierarchize and establish approaches for diligent SLE research, care and access to healthcare. Lack of access to high-cost medications that have been shown to be efficacious in the short term and that potentially reduce damage in SLE is a complex issue. In this review, we highlight opportunities and plans of action to diminish costs and improve access to therapies, which should be recognized and executed, preferably within regional strategies with multiple stakeholders (including supranational organizations, governments, the pharmaceutical industry, medical societies and the general population) connected with and grounded in structured and clear cost-effectiveness analysis.

OBJECTIVE: We carried out a systematic review (SR) of adherence in diagnostic and prognostic applications of ML in SLE using the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) Statement. METHODS: A SR employing five databases was conducted from its inception until December 2021. We identified articles that evaluated the utilization of ML for prognostic and/or diagnostic purposes. This SR was reported based on the PRISMA guidelines. The TRIPOD statement assessed adherence to reporting standards. Assessment for risk of bias was done using PROBAST tool. RESULTS: We included 45 studies: 29 (64.4%) diagnostic and 16 (35.5%) prognostic prediction- model studies. Overall, articles adhered by between 17% and 67% (median 43%, IQR 37-49%) to TRIPOD items. Only few articles reported the model's predictive performance (2.3%, 95% CI 0.06-12.0), testing of interaction terms (2.3%, 95% CI 0.06-12.0), flow of participants (50%, 95% CI; 34.6-65.4), blinding of predictors (2.3%, 95% CI 0.06-12.0), handling of missing data (36.4%, 95% CI 22.4-52.2), and appropriate title (20.5%, 95% CI 9.8-35.3). Some items were almost completely reported: the source of data (88.6%, 95% CI 75.4-96.2), eligibility criteria (86.4%, 95% CI 76.2-96.5), and interpretation of findings (88.6%, 95% CI 75.4-96.2). In addition, most of model studies had high risk of bias. CONCLUSIONS: The reporting adherence of ML-based model developed for SLE, is currently inadequate. Several items deemed crucial for transparent reporting were not fully reported in studies on ML-based prediction models. REVIEW REGISTRATION: PROSPERO ID# CRD42021284881.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by damage to multiple systems and a higher risk of cardiovascular disease. In addition, several studies have found that insulin resistance (IR) is more prevalent in SLE patients than controls, increasing the risk of prediabetes, type 2 diabetes mellitus (T2DM) and morbidity. The objective of this review article was to summarize the most relevant evidence about the relationship among IR, T2DM and SLE, including the effects of proinflammatory states, acute-phase proteins, pro-inflammatory cytokines, and pharmacological SLE treatment. A better understanding of the mechanisms involved in these comorbidities will allow better treatment strategies.

BACKGROUND: Hospitalizations due to systemic lupus erythematosus (SLE) incur substantial resource use. Hospitalization trends provide a key benchmark of the disease burden. However, there is little long-term data in Mexico. Therefore, we evaluated Mexican hospitalization trends for SLE during 2000-2019. METHODS: Hospitalization trends of SLE were studied using data from 2000 to 2019 releases of the National Dynamic Cubes of the General Direction of Health Information, which provides data on hospitalization discharges in Mexico. Patients aged ≥15 years hospitalized during the study period with a principal discharge diagnosis of SLE (ICD-10 code M32) were included. RESULTS: From 2000 to 2019, there were 17,081 hospitalizations for SLE, of which 87.6% were in females and 87% in subjects aged 15-44 years. From 2000 to 2019, the age-standardized hospitalization rate for patients with SLE increased from 0.38 per 100,000 persons to 0.65 per 100,000 persons with an average annual percentage change (APC) of 2.9% (95% CI 6.2-63.2). Although there was a significant uptrend from 2000 through 2011, there was a significant decline from 2011 to 2019 (APC: -4.8%, 95% CI -7.0% to -2.5%). Similar trends were identified in subjects aged 15-44 years and in both sexes. The length of stay and inpatient mortality decreased between 2000-2009 and 2010-2019. CONCLUSIONS: Although there was a substantial increase in SLE hospitalizations in 2000-2019, in 2011-2019, a decreased trend was reported in younger patients and in females and males. The length of stay was also reduced.

BACKGROUND: Patients with systemic lupus erythematosus (SLE) have an increased cardiovascular (CV) risk. Insulin resistance (IR), which is higher in patients with SLE, adversely impacts left ventricular (LV) remodeling and function. The aims were to determine LV dysfunction and evaluate the influence of potential risk factors on subclinical LV dysfunction in women with SLE, including IR. METHODS: This cross-sectional study included adult women with SLE without diabetes mellitus (DM), hypertension or severe obesity. Diastolic dysfunction (DD) was verified according to current guidelines. Insulin resistance was estimated using the Quantose score. RESULTS: We included 77 women. The frequency of IR was 65%. All participants had a normal ejection fraction (EF), and 11 (15.7%) had abnormal LV global longitudinal strain (GLS). Twenty-three (32.8%) had DD. The GLS% and global circumferential strain (GCS)% did not differ in patients with and without IR (-20.8 ± 3.1 vs -20.5 ± 2.1; p = 0.61 and -27.9 ± 4.4 vs -27.4 ± 3.7; p = 0.57, respectively). The prevalence of DD was 38.1% in patients with IR versus 25% in those without (p = 0.30). E/e' and E/A ratios did not differ between groups (6.6 ± 1.9 vs 6.6 ± 1.5; p = 0.98 and 1.3 ± 0.3 vs 1.3 ± 0.2; p = 0.27). Higher BMI (OR: 1.2, 95% CI 1.1-1.5) and disease duration (OR: 1.2, 95% CI 1.1-1.4) were associated with DD. CONCLUSIONS: Patients with overweight/obesity may be at higher risk of LV dysfunction. Although IR was high in our patients with SLE was not associated with systolic dysfunction or DD. Body mass index and disease duration were associated with an increased risk of DD.

PURPOSE: Undifferentiated connective tissue disease (UCTD) encapsulates a broad range of conditions including incomplete forms of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc), some of whom progress to a formal clinical diagnosis over time. This systematic review (SR) and meta-analysis aimed to identify clinical and laboratory features and biomarkers that can predict progression of UCTD. METHODS: A systematic literature search was carried out on MEDLINE, EMBASE and the Cochrane Central Register of Randomized Controlled Trials. Abstracts and full-text manuscripts were screened by two reviewers. Publications were included if they included at least 20 UCTD patients, a minimum of six months of follow up, and provided data on at least one risk factor for developing a defined CTD. The QUIPS tool was used to assess risk of bias (RoB) and GRADE for grading the quality of the evidence. The study is registered with PROSPERO (ID: CRD42021237725). RESULTS: Fifty-nine studies were included in the SR, and forty-one in the meta-analysis. The predictors for progression to SLE with the highest certainty of evidence included those with younger age (MD -5.96 [-11.05-0.87 years]), serositis (RR 2.69 [1.61-4.51]), or the presence of anti-dsDNA antibodies (RR 4.27 [1.92-9.51]). For SSc, the highest certainty of evidence included puffy fingers (RR [3.09 [1.48-6.43]), abnormal nailfold changes (NFC) (avascular areas [RR 5.71 (3.03-10.8)] or active or late SSc pattern [RR 2.24 (1.25-4.01)] and anti-topoisomerase-I (RR 1.83 [1.45-2.30]). No novel biomarkers were included in the meta-analysis; however HLA molecules, regulatory T cell shift, pro-inflammatory cytokines and complement activation products were identified as potential predictors for evolution of disease. CONCLUSIONS: Clinical and immunological parameters may predict which patients with UCTD progress to definitive disease; however, the heterogeneous nature and RoB in most studies limits the ability to apply these results in routine clinical practice. Limited data suggest that some novel biomarkers may provide additional predictive value but these will need larger well designed studies to fully delineate their clinical utility.

OBJECTIVE: To investigate national temporal trends over time in mortality rates in patients with systemic sclerosis (SSc) in Mexico between 1998 and 2017. METHODS: Deaths between 1998 and 2017 were extracted from General Board of Health Information (DGIS) Open Access datasets. 2We identified all persons aged ≥15 years with a diagnosis of SSc (ICD-10 code M34). We calculated the age-standardized mortality rate (ASMR) for SSc and non-SSc (information provided by the National Institute of Statistics, Geography, and Informatics). A Joinpoint regression model was used to determine mortality trends by sex and geographic regions. Annual percentage change (APC) and average APC (AAPC) were calculated using Joinpoint analysis. RESULTS: From 1998 to 2017, the overall ASMR of SSc increased (AAPC = 2.5%), whereas the ASMR for non-SSc remained stable. By subpopulations, females, and males with SSc had a significant uptrend in the ASMR (APC = 4.6 and 4.4%, respectively), between 1998 and 2008 for the former and between 1998 and 2010 for the later. Females had a non-significant ASMR uptrend between 2008 and 2017 and males a non-significant ASMR decline between 2010 and 2017. Women had a higher SSc-ASMR to non-SSc-ASMR ratio than males. The relative cumulative change between 1998 and 2017 differed between females (78.1%) and males (50.8%), and residents of the Southern region had the largest cumulative change (147.8%). CONCLUSIONS: SSc mortality rate increased in Mexico between 1998 to 2017, with SSc mortality higher than non-SSc mortality. However, the SSc mortality rate steeply increased in the first ten years but has plateaued in the last 10 years of the study period. Variations by sex and geographic regions were also identified.

Systemic lupus erythematosus (SLE) is one of the leading causes of death in younger adults, but advances in diagnosis and management during recent years may have reduced mortality. We examined whether SLE is a leading cause of death in Mexico among females. Data for death counts for the female population were obtained from the General Board of Health Information (DGIS) Open Access datasets, which evaluate death certificates, from 2000 to 2020. SLE was defined using the Tenth Revision of the International Classification of Disease codes: M32.1, M32.8, and M32.9. From 2000 to 2020, there were 12,114 deaths of females with SLE recorded as an underlying cause of death in Mexico. SLE ranked among the top 20 leading causes of death in females aged 10-54 years. SLE ranked fifteenth for deaths in people aged 15-24 years, sixteenth in those aged 25-34 years and 35-44 years, and eighteenth in those aged 45-54 years. After three frequent external injury causes of death were excluded from the analysis, focusing on the organic causes of death, SLE ranked twelfth in those aged 15-24 years and thirteenth in those aged 25-34 years and 35-44 years. In Mexico, SLE is among the leading causes of death in young females, emphasizing its significance as a public health issue.

OBJECTIVE: The role of vascular damage in cognitive dysfunction (CD) in SLE is not entirely understood. Nailfold capillaroscopy (NFC) is a noninvasive method that may aid the description of further vascular contributions to CD in SLE. Therefore, the aim of our study was to examine and compare finger nailfold capillary morphology in subjects with SLE with and without CD. METHODS: We conducted a cross-sectional study in patients with SLE. Demographic, clinical, and laboratory characteristics were collected. We evaluated nailfold capillary findings including avascular zones, hemorrhage, dilated and tortuous capillaries, disarrangement, crossing, subpapillary venular plexus, branched loops, and shortened loops by NFC. The Montreal Cognitive Assessment (MoCA) scale was used to screen cognitive function. CD was defined as a score < 26/30. RESULTS: Sixty-five females (97.0%) and 2 males (3%) with SLE were analyzed. Means of age and disease duration were 44.3 ± 12.0 years and 15.5 ± 7.6 years, respectively. Thirty-five (54.7%) patients had CD. The rate of patients with ≥ 1 NFC abnormality was 50% in both patients with and without CD (P = 0.14). Eight (22.8%) patients with CD compared to 1 without (3.5%) displayed dilated capillaries (P = 0.036). Other NFC abnormalities differed between patients with and without CD, but the possible relationships between dilated capillaries and CD disappeared after adjusting by age, diabetes, and hypertension. CONCLUSIONS: NFC findings were not associated with mild CD in patients with SLE. Our exploratory data do not support systemic microvasculopathy measured by NFC related to CD in patients with SLE.
