MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1920. [PMID: 38003970 PMCID: PMC10673265 DOI: 10.3390/medicina59111920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 10/22/2023] [Accepted: 10/26/2023] [Indexed: 11/26/2023]
Abstract
Background and Objectives: Treatment for antineutrophil cytoplasmic antibody-associated vasculitis (AAV) must deal with immunosuppression, as well as infections associated with a compromised immune system, such as tuberculosis (TB). Our aim was to examine the risk of incidental TB after diagnosis of AAV. Materials and Methods: This retrospective population-based cohort study was based on the data from the National Health Insurance Research Database in Taiwan. Patients with newly diagnosed granulomatous polyangiitis or microscopic polyangiitis were identified between 1 January 2000 and 31 December 2012. The primary outcome was risk of incidental TB. Cox proportional hazard models were used to evaluate the association between AAV and incidental TB. Results: A total of 2257 patients with AAV and a propensity-score matched cohort of 9028 patients were studied. Overall, patients with AAV were at a 1.48× higher risk of contracting incidental TB than the patients in the matched cohort (adjusted HR 1.48; 95% confidence interval [CI], 1.02-2.15). Note that the highest risk of contracting incidental TB was in the first two years following a diagnosis of AAV, with a nearly 1-fold increase in risk (adjusted HR, 1.91; 95% CI, 1.01-3.60). Female AAV patients were 3.24× more likely than females without AAV to develop TB (adjusted HR 3.24; 95% CI, 1.85-5.67). Conclusions: Patients with AAV exhibit a 48% elevated TB risk, notably, a 91% increase within the first two years postdiagnosis. Female AAV patients face a 3.24 times higher TB risk compared to females without AAV. This study is limited by potential misclassification and overestimation of AAV cases. Clinicians should closely monitor TB risk in AAV patients, especially in females and the initial two years following diagnosis.

Epidemiology of granulomatosis with polyangiitis and microscopic polyangiitis in adults in France. J Autoimmun 2022; 133:102910. [PMID: 36108505 DOI: 10.1016/j.jaut.2022.102910] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 08/30/2022] [Accepted: 08/31/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) are rare systemic necrotizing vasculitis. The national incidence and prevalence of GPA/MPA and patient mortality remain unknown in France. A real-life study using retrospective data from the French National Health Data System was set up to describe the epidemiology and demographic characteristics of hospitalized GPA and MPA patients, overall and by disease. METHODS All adult patients (≥18 years of age) hospitalized for GPA (ICD-10 M31.3) or MPA (ICD-10 M31.7) between 01 and 01-2010 and 31-12-2017 and affiliated to the General health insurance Scheme (covering 76% of the French population) were included in this national retrospective observational study. Descriptive analyses, univariate and multivariable logistic models, Kaplan-Meier survival analysis, and Cox models were performed. RESULTS The study involved 4445 prevalent GPA patients (including 1578 incident patients) and 1833 prevalent MPA patients (878 incident patients). Distinction between GPA and MPA diagnosis could not be made for 303 patients (149 incident patients). In people aged over 20 years, the age-standardized incidence rates of GPA and MPA were 0.5 and 0.3/100,000 person-years, respectively and the age-standardized prevalence rates were 10 and 4/100,000 person-years, respectively. The standardized mortality ratios in GPA and MPA patients aged over 20 years were 2.0 and 2.7, respectively, and remained constant. Renal failure, pulmonary and urinary tract infections, as well as coronary disease were more frequent among MPA than GPA patients. One-year survival rates among GPA and MPA patients were 96% (95%CI 94%-97%) and 94% (92%-95%), respectively. Five-year survival rates among GPA and MPA patients were 81% (95% CI 79%-83%) and 72% (68%-75%), respectively. After adjusting for comorbidities, the risk of death was still higher in MPA (hazard ratio 1.26 [95%CI 1.06-1.50]) than in GPA patients. CONCLUSIONS Despite advances in the therapeutic management of patients, mortality rates are still high and stable over time, highlighting the need for improved management.

Systematic Review and Metaanalysis of Worldwide Incidence and Prevalence of Antineutrophil Cytoplasmic Antibody (ANCA) Associated Vasculitis. J Clin Med 2022; 11:jcm11092573. [PMID: 35566698 PMCID: PMC9106044 DOI: 10.3390/jcm11092573] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 04/30/2022] [Accepted: 05/02/2022] [Indexed: 12/16/2022] Open
Abstract
Objective: In this study, we aimed to evaluate the worldwide incidence and prevalence of ANCA-associated vasculitis (AAV). Methods: A systematic search of Medline and Embase was conducted until June 2020 for studies that analyzed the incidence and prevalence of patients aged >16 years diagnosed with AAV in different geographical areas. A meta-analysis was undertaken to estimate the pooled incidence per million person-years and prevalence per million persons in AAV overall and for each subtype of AAV: granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). The 95% confidence interval (CI) and I2 for heterogeneity were calculated. Results: The meta-analysis included 25 studies that met the inclusion criteria and covered a total of 4547 patients with AAV. Frequency increased over time. The global pooled incidence (95% CI) was 17.2 per million person-years (13.3−21.6) and the global pooled prevalence (95% CI) was 198.0 per million persons (187.0−210.0). The pooled incidence per million person-years for each AAV subtype varied from highest to lowest, as follows: GPA, 9.0; MPA, 5.9; and EGPA, 1.7. The individual pooled prevalence per million persons was, as follows: GPA, 96.8; MPA, 39.2; and EGPA, 15.6. AAV was more predominant in the northern hemisphere. By continent, a higher incidence in America and pooled prevalence of AAV was observed in America and Europe. Conclusion: The pooled incidence and prevalence of AAV seem to be increasing over time and are higher in the case of GPA. AAV was generally more frequent (incidence and prevalence) in the northern hemisphere.

Abstract
Little is known about the epidemiology of systemic vasculitis in South American countries. The aim of this study is to compare the prevalence of systemic vasculitides in two vasculitis referral centers from Brazil and Peru. A cross-sectional study was performed and all patients above 18 years of age, with at least 6 months of follow-up and who met classification or diagnosis criteria for the most common forms of vasculitis, were included. A total of 562 patients with systemic vasculitis were analyzed, 345 (61.4%) from Brazil and 217 (38.6%) from Peru. The frequency of Behçet's disease (37.9% vs. 1.8%; p < 0.0001), Takayasu arteritis (TAK) (25.2% vs. 6.9%; p < 0.0001), and giant cell arteritis (9.8% vs. 0.9%; p < 0.0001) was higher in the Brazilian center than the Peruvian one. On the other hand, the frequency of microscopic polyangiitis (MPA) (67.3% vs. 2.8%; p < 0.0001) and renal-limited vasculitis (2.8% vs. 0.0%; p = 0.009) was higher in the Peruvian center. No differences were found concerning other forms of vasculitis. At diagnosis, Brazilian patients with TAK, granulomatosis with polyangiitis, and MPA were younger than Peruvian patients. Epidemiologic differences in the frequency of systemic vasculitis are observed between a vasculitis referral center from Brazil and another from Peru. Key Points • Significant differences are observed regarding the epidemiologic profile of systemic vasculitis between Brazil and Peru. • MPA is the predominant form of vasculitis in Peru while BD and TAK are the most frequent forms of vasculitis in Brazil. • The age at diagnosis of TAK, MPA, and GPA was lower in Brazilian patients than in Peruvian patients.

Abstract
ABSTRACT Most of the existing literature, including epidemiological studies and clinical trials, on antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) include North American (mainly United States and Canada), European, and Asian populations. Few studies have focused on multiethnic populations such as the one from Latin America. Racial and ethnic differences in the incidence of AAV could partially explain the comparatively low number of AAV studies originating in Latin America. However, given the racial/ethnic diversity as well as socioeconomic differences existing in this region, better reporting of AAV presentations and outcomes in Latin America could highlight valuable gaps on the understanding and treatment of these patients. Recently, larger case series and studies have provided better clinical information regarding AAV patients in Latin American countries; however, further information is needed to address gaps such as risk factors, genetic profiles, clinical features, and predictors of clinical outcomes. For these reasons, we have performed a systematic literature review to enhance our understanding of AAV patients in Latin America. We have included 11 articles focused on the epidemiological and clinical features of AAV in Latin America; some similarities and differences with AAV in other regions are shown in these articles. We have identified differences in their prevalence across Latin American countries, which may reflect reporting bias or true ethnic differences among the countries. Our findings should encourage further investigation into AAV in Latin America; such studies will hopefully lead to the optimal management of these patients.

Abstract
AIM The aim of this study was to identify the demographic and clinical features of patients with ANCA-associated vasculitides (AAVs) in a Peruvian tertiary referral hospital. METHODS Medical records of patients with AAV according to classification criteria or diagnosed by an experienced rheumatologist, and covering the period between January 1990 and December 2019, were reviewed. Granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA), and renal-limited vasculitis (RLV) were included. Demographic factors (age at diagnosis, sex), disease duration, clinical manifestations (per organ involvement), creatinine level at diagnosis (milligram per deciliter), ANCA status, diagnosis, 2009 Five Factor Score, disease categorization, and treatment were recorded. RESULTS Two hundred twelve patients were included. Their female-to-male ratio was 1.9:1 (139 [65.6%]/73 [34.4%]), and their mean (SD) age at diagnosis was 59.2 (12.5) years. One hundred fifty-eight patients (74.5%) had MPA, 42 (19.8%) GPA, 7 (3.3%) RLV, and 5 (2.4%) EGPA. Neurological, lung, and renal involvements were the most frequently affected systems. Myeloperoxidase preferentially occurred in MPA (82.5%), whereas proteinase 3 did occur in GPA (79.5%). Microscopic polyangiitis patients were older (61.1 [11.5] years). Female sex predominated in MPA and RLV (2.4:1 and 6:1, respectively), but the opposite was the case for EGPA (1:4). Ear-nose-throat and ocular involvement were more frequent in GPA (both p's < 0.001), and neurological and cardiovascular involvement were more frequent in EGPA (p < 0.001 and p = 0.002, respectively). CONCLUSIONS This is one of the largest series of AAV patients in Latin America. Overall, female sex predominated. Microscopic polyangiitis was the most frequent AAV, and myeloperoxidase-ANCA was the most frequent antibody in Peruvian AAV population.

Abstract
OBJECTIVES To compare the incidence of psoriatic arthritis (PsA) in patients with psoriasis (PsO) according to different treatments for their skin: topics/no treatment, conventional disease-modifying antirheumatic drugs (DMARDs) (cDMARDs) or biological DMARDs (bDMARDs). METHODS Patients with PsO without PsA followed at a university hospital were included in this retrospective cohort study. Patients were classified according to their treatment in topics (topics, phototherapy or no treatment), cDMARDs (methotrexate and cyclosporine) and bDMARDs (tumour necrosis factor inhibitors (TNFi), interleukin 17 inhibitors (IL-17i) and IL-12-23i ((interleukin (IL) 12/IL-23 inhibitor))) groups. Incident cases of PsA were attributed to one treatment if developed during the administration of that treatment. A Cox proportional hazards model was used to evaluate the adjusted risk of PsA development by treatment group. RESULTS 1719 patients with PsO contributed a total of 14 721 patient/years (py). 1387 (81%) patients were in the topics, 229 (13%) in cDMARDs and 103 (6%) in the bDMARDs group. During follow-up, 239 patients (14%) developed PsA (231 under topics, six under cDMARDs and two under bDMARDs). Global incidence was 1.6 per 100 py. The risk of developing PsA in patients with PsO treated with bDMARDs was significantly lower (incidence rate ratio (IRR)=0.26; 95% CI 0.03 to 0.94; p=0.0111), compared with topics, but not compared with cDMARDs (IRR=0.35; 95% CI 0.035 to 1.96; p=0.1007). Adjusted Cox proportional hazards regression analysis showed that male sex, nail involvement and higher body max index were associated with increased risk of developing PsA, while biologics use was protective (HR: 0.19; 95% CI 0.05 to 0.81). CONCLUSION Treatment with biologics in patients with PsO reduced the risk of PsA development.

Abstract
BACKGROUND To compare the incidence of osteoporotic fractures in patients with rheumatoid arthritis (RA) with matched controls from a university hospital. METHODS Consecutive RA patients (n = 100) were matched (age and sex) with controls (1:2). The follow-up period began at the index date, defined as the date of diagnosis for RA patients and the date of the first medical claim at the Health Management Organization (HMO) for non-RA patients. Fracture incidence rates per 1000 persons-years (PY) for distinct types of fractures were calculated. Multivariate cox regression analysis was performed to identify factors associated with fractures. RESULTS One hundred RA patients were followed for a total of 975.1 patients-years and 200 controls for 1485.7 patients-years. No difference was found in the overall fracture incidence rate per 1000 PY between RA and controls (19.5, 95% CI 12.7-28.6 vs 12.1, 95% CI 7.7-18.7, p = 0.07). In the Cox regression analysis, only age (HR 1.06, 95% CI 1.02-1.11, p = 0.006) and history of a prior fracture (HR 9.85, 95% CI 2.97-32.64, p < 0.001) were associated with fractures after the index date. The stratified analysis of the fractures by location showed that only the vertebral fractures were more frequent in RA patients compared with controls (12.9 per 1000 PY, 95% CI 8.9-25.8, vs. 3.4, 95% CI 1.4-8.1, respectively, p = 0.01). CONCLUSION Patients with RA didn't show an overall increased risk of osteoporotic fractures compared with matched controls, but vertebral fractures were more frequently observed in patients with RA.

Abstract
ANCA-associated vasculitides (AAV) comprise a group of systemic vasculitides characterized by inflammation of small-sized blood vessels leading to multi-organ involvement. The worldwide annual incidence of AAV ranges from 1.2 to 3.3 cases per 100 000 individuals with a prevalence of 4.6-42.1 cases per 100 000 individuals. The prevalence of AAV is geographically heterogeneous; therefore, regional epidemiological studies can be more informative to improve health care systems. Even though clinicians are aware that the healthcare burden and the risk of hospitalization of AAV appear high, data on hospitalization and cost of illness due to AAV are still scarce or even lacking. This study aims to characterize the economic burden of AAV in Friuli Venezia Giulia (FVG), Italy. Thus, a retrospective study was conducted through the integration of many administrative health databases of the FVG as the source of information. From data integration, we estimated that more than two-thirds of AAV patients showed at least one hospitalization in their medical history, most frequently caused by the disease itself or superimposed infections. Around 10% of patients developed end-stage renal disease. In an 8-year follow-up, the overall healthcare cost was € 1,215,078, corresponding to € 6,168 patient-year. ANCA-positive patients showed much higher costs than ANCA-negative patients did. Overall, AAV are rare diseases, but imply very high healthcare costs. Early diagnosis and optimal treatment probably still remain unmet needs for AAV.

Abstract
ANCA-associated vasculitis (AAV) includes granulomatosis with polyangiitis, microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis. Epidemiological studies in AAV are important in understanding possible aetiologic mechanisms and facilitating healthcare planning. However, epidemiological studies present a number of challenges including clear definition of cases differentiated from other clinical disorders, and identification of cases due to the rarity of AAV. The aim of this review is to summarize different aspects on the epidemiology of ANCA-associated vasculitis from different geographical areas throughout the world. During the past three decades, development of classification criteria worldwide, including the ACR classification of 1990, the Chapel Hill consensus definitions updated in 2012 and the EMA algorithm has facilitated epidemiology studies in AAV. The available epidemiological studies reported in AAV suggest that incidence and prevalence may have increased over the past 30 years. Possible explanations for this increase may be a genuine increase in incidence, the evolution of classification criteria and the definition, and availability and wider use of ANCA serology to aid diagnosis, and greater physician awareness through education. The age-specific incidence for the whole group of AAV showed a clear increase with age. However, there has been a clear shift in the peak age at onset towards a higher age during the last 20-30 years. In addition, variation in incidence of AAV between men and women has been clearly evident in a number of epidemiological studies.

Inpatient epidemiology and economic burden of granulomatosis with polyangiitis: a 10-year study of the national inpatient sample. Rheumatology (Oxford) 2021; 59:3685-3689. [PMID: 32129858 DOI: 10.1093/rheumatology/keaa069] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 01/25/2020] [Indexed: 02/06/2023] Open
Abstract
OBJECTIVE To characterize inpatient epidemiology and economic burden of granulomatosis with polyangiitis (GPA). METHODS Patients with GPA were identified from the Nationwide Inpatient Sample (NIS), the largest inpatient database in the USA consisting of over 4000 non-federal acute care hospitals, using the ICD-9 CM code. A cohort of comparators without GPA was also constructed from the same database. Data on demographics, procedures, length of stay, mortality, morbidity and total hospitalization charges were extracted. All analysed data were extracted from the database for the years 2005-2014. RESULTS The inpatient prevalence of GPA was 32.6 cases per 100 000 admissions. GPA itself (38.3%), pneumonia (13.7%) and sepsis (8.4%) were the most common reasons for admission. After adjusting for potential confounders, the all-cause mortality adjusted odds ratio (aOR) of patients with GPA was significantly higher than that of patients without GPA (aOR 1.20; 95% CI: 1.41, 1.61). This was also true for several morbidities, including acute kidney injury, multi-organ failure, shock and need for intensive care unit admission. Hospitalizations of patients with GPA were associated with higher cost as demonstrated by an adjusted additional mean of $5125 (95% CI: $4719, $5531) for total hospital cost and an adjusted additional mean of $16 841 (95% CI: $15 280, $18 403) for total hospitalization charges when compared with patients without GPA. CONCLUSION Inpatient prevalence of GPA was higher than what would be expected from prevalence in the general population. Hospitalizations of patients with GPA were associated with higher morbidity, mortality and cost.
