IKZF1plus is a frequent biomarker of adverse prognosis in Mexican pediatric patients with B-acute lymphoblastic leukemia.

Background: Recurrent genetic alterations contributing to leukemogenesis have been identified in pediatric B-cell Acute Lymphoblastic Leukemia (B-ALL), and some are useful for refining classification, prognosis, and treatment selection. IKZF1plus is a complex biomarker associated with a poor prognosis. It is characterized by IKZF1 deletion coexisting with PAX5, CDKN2A/2B, or PAR1 region deletions. The mutational spectrum and clinical impact of these alterations have scarcely been explored in Mexican pediatric patients with B-ALL. Here, we report the frequency of the IKZF1plus profile and the mutational spectrum of IKZF1, PAX5, CDKN2A/2B, and ERG genes and evaluate their impact on overall survival (OS) in a group of patients with B-ALL. Methods: A total of 206 pediatric patients with de novo B-ALL were included. DNA was obtained from bone marrow samples at diagnosis before treatment initiation. A custom-designed next-generation sequencing panel was used for mutational analysis. Kaplan-Meier analysis was used for OS estimation. Results: We identified the IKZF1plus profile in 21.8% of patients, which was higher than that previously reported in other studies. A significantly older age (p=0.04), a trend toward high-risk stratification (p=0.06), and a decrease in 5-year Overall Survival (OS) (p=0.009) were observed, although heterogeneous treatment protocols in our cohort would have impacted OS. A mutation frequency higher than that reported was found for IKZF1 (35.9%) and CDKN2A/2B (35.9%) but lower for PAX5 (26.6%). IKZF1MUT group was older at diagnosis (p=0.0002), and most of them were classified as high-risk (73.8%, p=0.02), while patients with CDKN2A/2BMUT had a higher leukocyte count (p=0.01) and a tendency toward a higher percentage of blasts (98.6%, >50% blasts, p=0.05) than the non-mutated patients. A decrease in OS was found in IKZF1MUT and CDKN2A/2BMUT patients, but the significance was lost after IKZF1plus was removed. Discussion: Our findings demonstrated that Mexican patients with B-ALL have a higher prevalence of genetic markers associated with poor outcomes. Incorporating genomic methodologies into the diagnostic process, a significant unmet need in low- and mid-income countries, will allow a comprehensive identification of relevant alterations, improving disease classification, treatment selection, and the general outcome.

Implementation of a roadmap for the comprehensive diagnosis, follow-up, and research of childhood leukemias in vulnerable regions of Mexico: results from the PRONAII Strategy.

The main objective of the National Project for Research and Incidence of Childhood Leukemias is to reduce early mortality rates for these neoplasms in the vulnerable regions of Mexico. This project was conducted in the states of Oaxaca, Puebla, and Tlaxcala. A key strategy of the project is the implementation of an effective roadmap to ensure that leukemia patients are the target of maximum benefit of interdisciplinary collaboration between researchers, clinicians, surveyors, and laboratories. This strategy guarantees the comprehensive management of diagnosis and follow-up samples of pediatric patients with leukemia, centralizing, managing, and analyzing the information collected. Additionally, it allows for a precise diagnosis and monitoring of the disease through immunophenotype and measurable residual disease (MRD) studies, enhancing research and supporting informed clinical decisions for the first time in these regions through a population-based study. This initiative has significantly improved the diagnostic capacity of leukemia in girls, boys, and adolescents in the regions of Oaxaca, Puebla, and Tlaxcala, providing comprehensive, high-quality care with full coverage in the region. Likewise, it has strengthened collaboration between health institutions, researchers, and professionals in the sector, which contributes to reducing the impact of the disease on the community.

Risk of Diabetes Mellitus in systemic lupus erythematosus: systematic review and meta-analysis.

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 analyzed the risk of DM in patients with SLE were included. The associations between diabetes and antirheumatic agents, such as antimalarials and glucocorticoids, were analyzed 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. CONCLUSIONS: 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.

Trends in the disease burden of musculoskeletal disorders in Mexico from 1990-2019.

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.

Non-invasive imaging in antiphospholipid syndrome to assess subclinical coronary artery disease.

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.

Low disease activity state associated with fewer incident vertebral fractures in Mestizo women with systemic lupus erythematosus.

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.

Trends in mortality in patients with systemic autoimmune rheumatic diseases (SARD) during the COVID-19 pandemic in Mexico.

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.

Subclassification of B-acute lymphoblastic leukemia according to age, immunophenotype and microenvironment, predicts MRD risk in Mexican children from vulnerable regions.

Introduction: The decisive key to disease-free survival in B-cell precursor acute lymphoblastic leukemia in children, is the combination of diagnostic timeliness and treatment efficacy, guided by accurate patient risk stratification. Implementation of standardized and high-precision diagnostic/prognostic systems is particularly important in the most marginalized geographic areas in Mexico, where high numbers of the pediatric population resides and the highest relapse and early death rates due to acute leukemias are recorded even in those cases diagnosed as standard risk. Methods: By using a multidimensional and integrated analysis of the immunophenotype of leukemic cells, the immunological context and the tumor microenvironment, this study aim to capture the snapshot of acute leukemia at disease debut of a cohort of Mexican children from vulnerable regions in Puebla, Oaxaca and Tlaxcala and its potential use in risk stratification. Results and discussion: Our findings highlight the existence of a distinct profile of ProB-ALL in children older than 10 years, which is associated with a six-fold increase in the risk of developing measurable residual disease (MRD). Along with the absence of CD34+ seminal cells for normal hematopoiesis, this ProB-ALL subtype exhibited several characteristics related to poor prognosis, including the high expression level of myeloid lineage markers such as MPO and CD33, as well as upregulation of CD19, CD34, CD24, CD20 and nuTdT. In contrast, it showed a trend towards decreased expression of CD9, CD81, CD123, CD13, CD15 and CD21. Of note, the mesenchymal stromal cell compartment constituting their leukemic niche in the bone marrow, displayed characteristics of potential suppressive microenvironment, such as the expression of Gal9 and IDO1, and the absence of the chemokine CXCL11. Accordingly, adaptive immunity components were poorly represented. Taken together, our results suggest, for the first time, that a biologically distinct subtype of ProB-ALL emerges in vulnerable adolescents, with a high risk of developing MRD. Rigorous research on potential enhancing factors, environmental or lifestyle, is crucial for its detection and prevention. The use of the reported profile for early risk stratification is suggested.

Trends in all-cause hospitalizations for systemic lupus erythematosus in Mexico, 2000-2019.

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.

Acute Promyelocytic Leukemia: A Long-Term Retrospective Study in Mexico.

BACKGROUND: The present retrospective study reviewed acute promyelocytic leukemia (APL) cases recorded in Mexico between January 2007 and January 2017. The primary objective of the study was to evaluate overall survival (OS) in Mexican patients with APL. Secondary objective was to evaluate the impact of induction treatment with different anthracyclines on OS, event-free survival (EFS) and complications in this patient population. METHODS: The medical charts of patients referred to medical institutions in Mexico from January 2007 through January 2017 for the treatment of suspected APL were reviewed retrospectively. Patients aged 15 - 75 years, in whom the diagnosis of APL was confirmed, who had an Eastern Cooperative Group performance status of 0 - 2, and who were eligible for combined treatment with intensive chemotherapy and all-trans retinoic acid (ATRA), were included in the study. Study participants received induction and consolidation treatment with ATRA plus either daunorubicin or idarubicin, followed by 2 years of single-agent ATRA as maintenance therapy. Patients who were unable to pay for ATRA treatment received anthracycline-based induction and consolidation, with methotrexate plus mercaptopurine as maintenance therapy. RESULTS: A total of 360 patients from 21 public and private hospitals were included in the study. The median age of the population was 37 years, and 51% were male. Of the 360 patients, 205 (57%) vs. 155 (43%) received daunorubicin vs. idarubicin as induction treatment for APL. ATRA was administered to 201 (98%) patients in the daunorubicin group vs. 138 (89%) in the idarubicin group (P = 0.001), and was initiated at diagnosis in 92% vs. 73% of recipients, respectively (P = 0.0001). At 150 months, OS and EFS for the entire population were 84% and 79%, respectively. Both OS (90% vs. 76%, P = 0.003) and EFS (85% vs. 72%, P = 0.001) were significantly prolonged in daunorubicin vs. idarubicin recipients. Rates of complications were similar in the two groups. CONCLUSIONS: As arsenic trioxide (ATO) is not currently available in Mexico, anthracycline plus ATRA is the mainstay of treatment for APL here. Our results confirm the efficacy of this strategy, with high OS and EFS rates being observed 12.5 years after diagnosis.

Treating Acute Leukemia During the COVID-19 Pandemic in an Environment With Limited Resources: A Multicenter Experience in Four Latin American Countries.

PURPOSE: The COVID-19 pandemic is a colossal challenge for global health; nonetheless, specific subgroups face considerably higher risks for infection and mortality. Among patients with malignant diseases, those with hematologic neoplasms are at a higher risk for poor outcomes. The objective of this study was to register treatment modifications associated with the COVID-19 pandemic and their short-term consequences in Latin America. METHODS: Multicenter, prospective, observational, cohort study including patients older than 14 years from 14 centers in four countries (Mexico, Peru, Guatemala, and Panama) who had a confirmed diagnosis of acute leukemia, and who were undergoing active treatment since the first COVID-19 case in each country until the cutoff on July 15, 2020. RESULTS: We recruited 635 patients. Treatment modifications because of the COVID-19 pandemic were reported in 40.8% of cases. The main reason for such modifications was logistic issues (55.0%) and the most frequent modification was chemotherapy delay (42.0%). A total of 13.1% patients developed COVID-19 disease, with a mortality of 37.7%. Several factors were identified as independently associated with mortality, including a diagnosis of acute myeloid leukemia (odds ratio 2.38 [95% CI, 1.47 to 3.84]; P < .001), while the use of telemedicine was identified as a protective factor (odds ratio 0.36 [95% CI, 0.18 to 0.82]; P = .014). CONCLUSION: These results highlight the collateral damage of COVID-19 in oncology patients.

Acute Myeloid Leukemia in Mexico: The Specific Challenges of a Developing Country. Results From a Multicenter National Registry.

BACKGROUND: In the past decades, long-term survival outcomes for younger patients with acute myeloid leukemia (AML) have improved. Nonetheless, developing nations might be lagging behind, highlighting the need to assess real-world outcomes in such regions. METHODS: We performed a multicenter retrospective study, which included patients with AML diagnosed between January 2013 and December 2017 from 13 centers in Mexico. RESULTS: A total of 525 patients with AML met the inclusion criteria and were included in the study. Median age for the entire cohort was 47 years. The patients were classified according to cytogenetic risk: favorable 16.0%, intermediate 55.6%, and unfavorable 28.4%. Most patients received intensive chemotherapy (80.2%), and among these 74.1% underwent a 7 + 3 induction regimen. A complete remission was achieved in 71.3% of patients. Induction-related mortality occurred in 17.8% and we identify the following as independent risk factors: >60 years (odds ratio [OR] 2.09 [1.09-4.02]), Eastern Cooperative Oncology Group >2 (OR 4.82 [2.46-9.43]), prior solid tumor (OR 3.8 [1.24-11.59]) and active infection (OR 1.82 [1.06-3.12]). Further, allogeneic hematopoietic stem-cell transplantation (AlloHSCT) was performed in 8.2% in CR1. The 3-year overall survival (OS) was 34.8%. In a multivariate analysis, several factors were independently associated with a worse OS, including secondary AML (hazard ratio [HR] 2.14 [1.15-4.01]) and unfavorable cytogenetic risk (HR 1.81 [1.16-2.82]), whereas maintenance therapy (HR 0.53 [0.32-0.86]) and AlloHSCT (HR 0.40 [0.17-0.94]) were associated with better OS. CONCLUSIONS: This is the first multicenter report analyzing AML survival in Mexico. Challenges in this setting include a high induction-related mortality and low AlloHSCT rate, which should be addressed to improve outcomes.

Hematopoietic stem cell transplantation in Puebla, México. Traveled roadand goals achieved

Introduction: In México there are only 4 cities that have significantly active hematopoietic stem cell transplantation programs; onlyin 3 of those cities, the most important national public health institution IMSS (Mexican Social Security Institute) count with them. The cities where these programs are found are Mexico City, Monterrey and Puebla. Since the beginning of this decade, and before, the productivity of these transplant programs in this public health institution is low, performing on average 148 transplants every year. Results: In the span comprised between April 1995 and October 2016, we have performed 474 hematopoietic transplants in our hospital; 229 of them were allogeneic and 245 autologous, in adult and children population. This accumulated experience has allowed the implementation of all the variety of hematopoietic stem cell transplantation available in our country, this has opened up the opportunity, for the first time in our institution, the possibility to provide a donor for every patient who requires an hematopoietic transplant, overcoming the phase in which patients could not be submitted to the procedure for lack of a compatible donor. Conclusions: The goals achieved in our hospital confirm the feasibility in developing uninterrupted long term transplant programs in hospitals not specially equipped with technology nor abundant funds of the public health system in the national province, and it shows that this programs can be created and developed in hospitals with similar conditions to ours in México, Latin America and middle-low income countries(AU)

Introducción: en méxico solo cuatro ciudades cuentan con programas de trasplante hematopoyético significativamente activos y en solo tres los tiene el IMSS, la principal institución de salud del país: Monterrey, Puebla y la ciudad de México .La productividad de estos centros del sector público es muy baja, realizando en conjunto 148 trasplantes en promedio por año desde el principio de la década actual. Resultados: en el lapso comprendido entre abril de 1995 y octubre de 2016, se efectuaron 474 trasplantes hematopoyéticos en nuestro hospital; 229 de ellos fueron alogénicos y 245 fueron autólogos, en población adulta e infantil. Esta experiencia acumulada ha permitido la implementación de todas las variedades disponibles en el país de estos procedimientos, lo que ha generado, por vez primera en la institución, poder contar con un donante para todo paciente que requiera un trasplante hematopoyético; superándose la etapa en la que los enfermos no se sometían al procedimiento por falta de un donador compatible. Conclusiones: la actividad acumulada en nuestra unidad hospitalaria confirma la factibilidad de desarrollar programas ininterrumpidos, a largo plazo, de estos procedimientos terapéuticos en hospitales no especialmente dotados de tecnología ni presupuesto del sector público de la provincia nacional y denota que estos mismos programas pueden ser creados y desarrollados en nosocomios con condiciones similares al nuestro en diversos territorios de México, de Latinoamérica y de países con ingreso medio-bajo(AU)

The impact of glucocorticoids and anti-cd20 therapy on cervical human papillomavirus infection risk in women with systemic lupus erythematosus

OBJECTIVE: To identify the prevalence and factors associated with cervical human papillomavirus infection in women with systemic lupus erythematosus METHODS: This cross-sectional study collected traditional and systemic lupus erythematosus-related disease risk factors, including conventional and biologic therapies. A gynecological evaluation and cervical cytology screen were performed. Human papillomavirus detection and genotyping were undertaken by PCR and linear array assay. RESULTS: A total of 148 patients were included, with a mean age and disease duration of 42.5±11.8 years and 9.7±5.3 years, respectively. The prevalence of squamous intraepithelial lesions was 6.8%. The prevalence of human papillomavirus infection was 29%, with human papillomavirus subtype 59 being the most frequent. Patients with human papillomavirus were younger than those without the infection (38.2±11.2 vs. 44.2±11.5 years, respectively; p = 0.05), and patients with the virus had higher daily prednisone doses (12.8±6.8 vs. 9.7±6.7 mg, respectively; p = 0.01) and cumulative glucocorticoid doses (14.2±9.8 vs. 9.7±7.3 g, respectively; p = 0.005) compared with patients without. Patients with human papillomavirus infection more frequently received rituximab than those without (20.9% vs. 8.5%, respectively; p = 0.03). In the multivariate analysis, only the cumulative glucocorticoid dose was associated with human papillomavirus infection. CONCLUSIONS: The cumulative glucocorticoid dose may increase the risk of human papillomavirus infection. Although rituximab administration was more frequent in patients with human papillomavirus infection, no association was found. Screening for human papillomavirus infection is recommended in women with systemic lupus erythematosus. .
