Abstract
IgA-associated vasculitis (IgAV) known as Henoch - Schönlein purpura (HSP) disease is an inflammatory disorder of small blood vessels. It's the most common type of systemic vasculitis in children which can be associated with the inflammatory process following infections. IgA vasculitis is a rare and poorly understood systemic vasculitis in adults. Coronavirus disease 2019 (COVID-19) has been associated with HSP in both adults and children. A 58-year-old woman was diagnosed with HSP, fulfilling the clinical criteria: palpable purpura, arthritis, hematuria. The disclosure of the HSP disease was preceded by a infection of the respiratory tract. COVID-19 infection was confirmed via the presence of IgM and IgG antibodies. This case indicates the possible role of SARS-CoV-2 in the development of HSP. The clinical course of IgAV in adults appears to be different from pediatric IgAV, especially due to higher risk of renal complications. Symptoms of the disease quickly resolved with low-dose of steroids.

Abstract
Palpable purpura, gastrointestinal symptoms, joint involvement, and renal disease characterize immunoglobulin A vasculitis (IgAV). Renal involvement ranging from mild proteinuria to severe nephritic or nephrotic syndrome highlights the importance of monitoring kidney function in patients with IgAV. Recognizing these key features is crucial for early diagnosis and appropriate management to prevent long-term complications related to kidney disease. However, the pathogenesis of IgAV remains unclear. Disease mechanisms involve various factors, including the interplay of aberrantly glycosylated IgA, anti-endothelial cell antibodies, and neutrophils following infection triggers, which are the main pathogenic mechanisms of IgAV. Insights from cases of IgAV related to Coronavirus disease 2019 have offered additional understanding of the connection between infection and IgAV pathogenesis. This review provides a valuable resource for healthcare professionals and rheumatology researchers seeking a better understanding of the clinical features and pathophysiology of IgAV.

Abstract
INTRODUCTION Immunoglobulin A vasculitis (IgAV) in adults has a variable disease course, with patients often developing gastrointestinal and renal involvement and thus contributing to higher mortality. Due to understudied molecular mechanisms in IgAV currently used biomarkers for IgAV visceral involvement are largely lacking. Our aim was to search for potential serum biomarkers based on the skin transcriptomic signature. METHODS RNA sequencing analysis was conducted on skin biopsies collected from 6 treatment-naïve patients (3 skin only and 3 renal involvement) and 3 healthy controls (HC) to get insight into deregulated processes at the transcriptomic level. 15 analytes were selected and measured based on the transcriptome analysis (adiponectin, lipopolysaccharide binding protein (LBP), matrix metalloproteinase-1 (MMP1), C-C motif chemokine ligand (CCL) 19, kallikrein-5, CCL3, leptin, C-X-C motif chemokine ligand (CXCL) 5, osteopontin, interleukin (IL)-15, CXCL10, angiopoietin-like 4 (ANGPTL4), SERPIN A12/vaspin, IL-18 and fatty acid-binding protein 4 (FABP4)) in sera of 59 IgAV and 22 HC. Machine learning was used to assess the ability of the analytes to predict IgAV and its organ involvement. RESULTS Based on the gene expression levels in the skin, we were able to differentiate between IgAV patients and HC using principal component analysis (PCA) and a sample-to-sample distance matrix. Differential expression analysis revealed 49 differentially expressed genes (DEGs) in all IgAV patient's vs. HC. Patients with renal involvement had more DEGs than patients with skin involvement only (507 vs. 46 DEGs) as compared to HC, suggesting different skin signatures. Major dysregulated processes in patients with renal involvement were lipid metabolism, acute inflammatory response, and extracellular matrix (ECM)-related processes. 11 of 15 analytes selected based on affected processes in IgAV skin (osteopontin, LBP, ANGPTL4, IL-15, FABP4, CCL19, kallikrein-5, CCL3, leptin, IL-18 and MMP1) were significantly higher (p-adj < 0.05) in IgAV serum as compared to HC. Prediction models utilizing measured analytes showed high potential for predicting adult IgAV. CONCLUSION Skin transcriptomic data revealed deregulations in lipid metabolism and acute inflammatory response, reflected also in serum analyte measurements. LBP, among others, could serve as a potential biomarker of renal complications, while adiponectin and CXCL10 could indicate gastrointestinal involvement.

Abstract
The immune-mediated small vessel vasculitis is known as Schoenlein-Henoch purpura predominantly from pediatrics and in these cases occurs more frequently after infections of the upper airways. In adults, immunoglobulin A (IgA) vasculitis often proceeds more severely und recurrently with the classical tetrad of skin manifestations in the sense of leukocytoclastic vasculitis, joint affection, gastrointestinal involvement and IgA nephritis, in contrast to the mostly mild and self-limiting course in children. The background of this systemic vasculitis with formation of IgA immune complexes is considered to be an altered glycosylation of IgA, as this causes the exposure of binding sites for autoantibodies so that an immune complex reaction can be elicited. This ultimately leads to perivascular deposition of IgA and a further activation of neutrophils. Groundbreaking in the diagnostics is the histological detection of leukocytoclastic vasculitis and in cases of renal manifestations a kidney biopsy with characteristic deposits of immune complexes, which cannot be clearly differentiated from IgA nephropathy. The treatment is aimed at the respective manifestation and is mostly based on consensus recommendations due to the lack of randomized studies. In addition to immunosuppressive medication, in the presence of a chronic kidney disease general nephroprotection is becoming increasingly more important also by inhibition of sodium-glucose transporter 2 (SGLT2). The type and extent of kidney involvement and also rare cardiac manifestations are the main determinants of the prognosis. Continuous medical accompaniment of those affected is necessary due to the possible progression of the disease and the risk of recurrence.

Abstract
Background This study aims to evaluate the immunological features of gastrointestinal (GI) bleeding in children with Henoch-Schönlein purpura (HSP). Study Design This retrospective study was conducted on children with HSP. Demographic and clinical data were collected, including serum immunoglobulin (Ig) levels, complement C3 and C4 levels, and lymphocyte subtype percentage. Results A total of 446 hospitalized children had HSP. Eighty-six children with HSP had GI bleeding, 114 had proteinuria, and 107 had hematuria. Lower arthralgia, prolonged glucocorticoid use, increased white blood cell counts, elevated neutrophils and neutrophil-to-lymphocyte ratio, reduced IgG and C3 levels, elevated CD19+ cell percentage, and reduced CD3+ cell and natural killer cell percentages were associated with GI bleeding risk in patients with HSP. Multivariate regression analysis revealed that arthralgia, glucocorticoid use, increased neutrophil percentage, reduced IgG and C3 levels, and increased CD19+ cell percentage were independent predictors of GI bleeding. Further analysis indicated that the combination of C3 and CD19+ cell percentages had a high predictive ability for GI bleeding in children with HSP. Conclusion This study indicated that reduced C3 and increased CD19+ cell percentages contributed to the development of GI bleeding in children with HSP. Specific immunologic profiles may be strongly correlated with GI bleeding risk in children with HSP.

Abstract
IgA vasculitis (IgAV) is an immune complex-mediated vasculitis characterized by IgA1-dominant immune deposits in small vessels. It is the most common systemic vasculitis in childhood with a mostly uncomplicated and self-limiting course. Adults are less affected but the course is frequently more complicated and more frequently accompanied by renal involvement. IgAV characteristically manifests itself on the skin with palpable purpura and in joints, the kidneys and the gastrointestinal tract. In cases of incomplete or atypical symptoms a differential diagnostic work-up is required. A number of triggers have been suggested, especially infections and drugs. Disease management is tailored to organ manifestations and the severity of the symptoms. For children, optimized supportive care and targeted symptom relief are usually sufficient. Management of renal and gastrointestinal manifestations follows recommendations for ANCA-associated vasculitis and IgA nephropathy. Treatment options include glucocorticoids and immunosuppressive agents with varying and mostly insufficient evidence.

Abstract
Background Follow-up data on IgA vasculitis (IgAV) in adults are scarce. We aimed to investigate the outcome of adult IgAV in a well-defined cohort. Methods Data from histologically proven patients diagnosed between January 2010 and July 2022 with at least a 3-month follow-up were analyzed. The frequency and type of relapses and information on kidney function were extracted. Risk factors for IgAV relapse and decline in renal function were studied using the Cox hazards regression analysis. Mortality in IgAV was assessed using the Kaplan-Meier analysis and the standardized mortality ratio (SMR). Results In total, 265 patients were followed for a median of 24 months. At baseline, 38.9, 29.8, and 44.5% had articular, gastrointestinal, and renal involvement, respectively. Initially, 189 (71.3%) patients received systemic glucocorticoids, and 32 (12.1%) patients received an additional immunomodulator. During follow-up, 42 (15.8%) patients relapsed. Relapses were more common in younger patients (HR 1.03 [95%CI 1.01-1.05]) and those without baseline glucocorticoid treatment (HR 3.70 [95%CI 2.0-6.67]). Furthermore, 74 (27.9%) patients had persistent abnormal urinalysis and a substantial (≥20%) decline in glomerular filtration rate (eGFR) was recorded in 41 (15.5%) patients. The factors associated with persistent abnormal urinalysis were an absence of IgAV joint involvement and baseline immunomodulatory treatment. Pre-existent chronic kidney disease and heart failure were associated with eGFR decline. The overall SMR was 1.4 (95%CI 1.14-1.71) compared to the Slovenian general population. Conclusion IgAV relapses occurred in 15% of patients, with younger patients with symptomatically managed IgAV experiencing it more frequently. Heart failure emerged as a predictor of persistent abnormal urinalysis and a decline in eGFR. Adults with IgAV had increased mortality compared to the general population.

Abstract
Objective To illustrate the association of monocyte to high-density lipoprotein cholesterol ratio (MHR) and other serum indicators with the pathogenesis and prognosis of immunoglobulin A vasculitis (IgAV) patients in different subgroups. Methods A total of 158 adult patients and 113 healthy controls were enrolled, and the clinical presentation and laboratory indexes were comprehensively assessed. Results IgAV patients show significantly elevated levels of inflammatory parameters and lipid profiles compared to healthy controls (P < 0.05). Higher levels of the MHR and other normal inflammatory indicators were found in patients with Gastrointestinal (GI) involvement compared to other subgroups. And in group with GI involvement, significantly higher white blood cell (WBC), neutrophil, complement 4 (C4), NLR (neutrophil-to-lymphocyte ratio) and PLR (platelet-to-lymphocyte ratio) levels and lower levels of apolipoprotein-a (Apo-a) were observed. Their correlation analysis demonstrated positive results between MHR level and white blood cell (WBC) count (r = 0.416, P = 0.034), D-Dimer (r = 0.464, P = 0.026) and monocyte (r = 0.947, P < 0.001). And the time until first remission of skin purpura was shown positively correlated with their age (r = 0.456, P = 0.043), C-reactive protein (CRP) level (r = 0.641, P = 0.018), D-Dimer level (r = 0.502, P = 0.040) while negatively correlated with albumin (Alb) level (r=-0.626, P = 0.003) and low-density lipoprotein (LDL) level (r=-0.478, P = 0.033). Conclusion Our study suggests that those biomarkers represented for inflammatory responses, lipid profile and immunological functions have significant differences in the subgroups of adult IgAV patients. In addition, we also found that MHR level may serve as a potential biomarker for the pathogenesis and prognosis of IgAV patients with GI involvement.

Abstract
BACKGROUND This study aimed to investigate the characteristics of patients with preadolescent- and adolescent-onset immunoglobulin A vasculitis (IgAV) and to determine whether age affects IgAV outcomes in adolescents. METHODS Demographic, clinical, and laboratory data of 333 patients diagnosed with IgAV at the Department of Pediatric Rheumatology, University of Health Sciences, Ankara City Hospital, were evaluated retrospectively. The patients were classified into two groups: preadolescents (<10 years) and adolescents (10-19 years). Subgroup analyses were also performed by grouping the adolescent patients into early, middle, and late adolescent groups. RESULTS Of the 333 patients, 219 (65.8%) and 114 (34.2%) were preadolescents and adolescents. Palpable purpura, renal, joint, and gastrointestinal (GI) tract involvement were detected in 333 (100%), 78 (23.4%), 79 (23.7%), and 124 (37.2%) patients, respectively; testicular involvement was observed in 25 (13.3%) of 187 male patients. The frequency of renal involvement was significantly higher in the adolescent group than in the preadolescent group at the time of diagnosis (p = 0.030). Notably, joint involvement was significantly higher in the adolescent group (p = 0.001). The need for aggressive therapy was significantly higher in the adolescent group than in the preadolescent group (p = 0.003). There was no significant difference in clinical data, demographic characteristics, and laboratory findings between the adolescent subgroups (p > 0.05). CONCLUSIONS Immunoglobulin A vasculitis can occur at any age but the disease prognosis appears to worsen with age. The present study reported that joint involvement, kidney involvement, and the need for more aggressive treatment were higher in the adolescent group than in the preadolescent group.

Abstract
Immune deposits/complexes are detected in a multitude of tissues in autoimmune disorders, but no organ has attracted as much attention as the kidney. Several kidney diseases are characterised by the presence of specific configurations of such deposits, and many of them are under a 'shared care' between rheumatologists and nephrologists. This review focuses on five different diseases commonly encountered in rheumatological and nephrological practice, namely IgA vasculitis, lupus nephritis, cryoglobulinaemia, anti-glomerular basement membrane disease and anti-neutrophil cytoplasm-antibody glomerulonephritis. They differ in disease aetiopathogenesis, but also the potential speed of kidney function decline, the responsiveness to immunosuppression/immunomodulation and the deposition of immune deposits/complexes. To date, it remains unclear if deposits are causing a specific disease or aim to abrogate inflammatory cascades responsible for tissue damage, such as neutrophil extracellular traps or the complement system. In principle, immunosuppressive therapies have not been developed to tackle immune deposits/complexes, and repeated kidney biopsy studies found persistence of deposits despite reduction of active inflammation, again highlighting the uncertainty about their involvement in tissue damage. In these studies, a progression of active lesions to chronic changes such as glomerulosclerosis was frequently reported. Novel therapeutic approaches aim to mitigate these changes more efficiently and rapidly. Several new agents, such as avacopan, an oral C5aR1 inhibitor, or imlifidase, that dissolves IgG within minutes, are more specifically reducing inflammatory cascades in the kidney and repeat tissue sampling might help to understand their impact on immune cell deposition and finally kidney function recovery and potential impact of immune complexes/deposits.

Abstract
Immunoglobulin A vasculitis (IgAV), formerly known as Henoch-Schönlein purpura, is the most common systemic vasculitis in children, characterized by diverse clinical manifestations with a wide spectrum ranging from isolated cutaneous vasculitis to systemic involvement. The incidence of IgAV is geographically and ethnically variable, with a prevalence in autumn and winter, suggesting a driving role that genetic and environmental factors play in the disease. Although IgAV has a certain degree of natural remission, it varies widely among individuals. Some patients can suffer from severe renal involvement and even progress to end-stage renal disease. Its pathogenesis is complex and has not been fully elucidated. The formation of galactose-deficient IgA1 (Gd-IgA1) and related immune complexes plays a vital role in promoting the occurrence and development of IgAV nephritis. In addition, neutrophil activation is stimulated through the binding of IgA to the Fc alpha receptor I expressed on its surface, resulting in systemic vascular inflammation and tissue damage. Starting from the epidemiological characteristics, this article will review the role of immunological factors such as Gd-IgA1, autoantibodies, circulating immune complexes, complement system, cellular immunization, and the contributions of environmental and genetic factors in the pathogenesis of IgAV, and conclude with the major biomarkers for IgAV.

Abstract
Background IgA vasculitis in adults has not been thoroughly studied. This has left a practice gap related to the management and follow-up of a population that is at an increased risk of comorbidities and potentially poor outcomes. For this reason, it is important to synthesize evidence from the current literature because this can help direct the movement for more robust studies to clarify best practice recommendations. Objective We sought to create a narrative review for the practicing dermatologist when diagnosing and leading the care of IgA vasculitis in adult patients. Methods A broad literature search was performed with a focus on articles that were published after the introduction of the most updated European Alliance of Associations for Rheumatology/Pediatric Rheumatology International Trials Organization/Pediatric Rheumatology European Society criteria. Results The characteristics and management guidelines for IgA vasculitis in adults have been refined, although more rigorous studies are needed to develop best practice recommendations. Limitations Because of the lack of sufficient randomized controlled trials on IgA vasculitis in adults, this narrative review is composed of mostly observational, descriptive studies. Conclusion Adults with IgA vasculitis are at an increased risk of complicated disease course, necessitating formal diagnostic assessment and clear-cut follow-up recommendations to manage and prevent poor health outcomes related to various comorbidities.

Int Immunopharmacol 2022; 111:109178. [PMID: 36027850 DOI: 10.1016/j.intimp.2022.109178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 08/12/2022] [Accepted: 08/15/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND Skin-limited IgAV patients usually present self-limiting disease and good prognosis, while adult IgA vasculitis with nephritis (IgAV-N) present severe phenotype and poor prognosis. Previous studies showed that neutrophil-to-lymphocyte ratio (NLR) was an inflammatory indicator for predicting systemic involvement in children IgAV patients. In this study, we focused on adult IgAV-N patients to explore the relationship of NLR with disease phenotype and long-term renal prognosis. METHODS In this study, 245 IgAV-N patients, 1151 IgAN patients and 251 healthy controls were recruited. Composite endpoint was defined as 30% eGFR declined or end stage kidney disease. RESULTS IgAV-N patients presented increased white blood cells (WBC), neutrophils (NE), platelet-to-lymphocyte ratio (PLR), and NLR levels, while decreased lymphocyte (LY) than healthy controls. When compared to clinical and pathological features matched IgAN patients, IgAV-N patients still showed higher WBC, NE, and NLR levels. NLR showed the best performance for the diagnosis of IgAV-N with the highest area under the ROC curves (0.738). IgAV-N patients in high NLR group (>2.41) presented with sever baseline manifestations and more acute pathological lesions than low NLR group (≤2.41). 77 patients with regular follow-up were used for survival analysis. After adjusting some well-known risk factors, NLR levels remained as an independent risk factor for poor renal outcome in adult patients with IgAV-N (HR, 1.913; 95% CI, 1.314 to 2.787, P = 0.001). CONCLUSIONS NLR levels were associated with the clinical and pathological phenotypes, and NLR may serve as an independent risk factor for poor renal outcome in adult IgAV-N patients.

Abstract
A 47-year-old female presented with complaints of abdominal pain and a history of new-onset maculopapular rash. A workup including laboratory and imaging studies, colonoscopy, and biopsy was performed that led to the diagnosis of adult-onset IgA vasculitis. The patient responded well to intravenous methylprednisolone and was followed up as an outpatient where she continued with oral methylprednisolone and azathioprine. This case is noteworthy for the unusual adult-onset presentation with primarily gastrointestinal symptoms and atypical rash pattern. Furthermore, while very effective in this patient, the use of corticosteroids is a treatment decision that has some controversy in the current literature.

Abstract
We report the case of a 29-year-old adult presenting with severe IgA vasculitis, with cutaneous, urologic, and renal manifestations. The late appearance of severe gastrointestinal bleeding dominated the clinical picture, necessitating the administration of tens of units of packed cells and the augmentation of the immunosuppressive protocol. It was not until therapy with intravenous immunoglobulin (IVIG) was introduced that the massive bleeding was controlled. We herein discuss the patient's presentation, the gastrointestinal manifestations of IgA vasculitis, the recommended treatments, and the existent evidence about IVIG therapy.

Abstract
Hemorrhagic vasculitis (HV) is a systemic disease of widespread inflammation in small vessels, arterioles, small capillaries, and perivascular edema with blood cells infiltration. The pathogenesis of HV are currently not well understood, and insufficient investigators attention is given to this disease.
It has been established that patients with HV often have sonographic signs of the liver damage with normal liver tests, which indicates the presence of hepatic steatosis (HS).
The ratio of neutrophilic granulocytes to lymphocytes (N/L) is widely used by doctors to determine the activity of the process, but in patients with HV, depending on the presence of HS, it was not evaluated.
The objective: to analyze the diagnostic capabilities of the N/L ratio in HV adult patients.
Materials and methods. The retrospective analyse of the hospital examination results of 50 patients with HV was performed and included data from 20 men and 30 women aged 45.96±2.04 years. The patients were divided into two groups: the main group – 15 men and 16 women with HS, and the control group – 5 men and 14 women with sonographically and laboratory intact liver, in whom the N/L index was additionally determined.
Statistic of the study was performed by use Statistica 6.0 program, correlations were assessed by Pearson method (r); p<0.05 was taken as the significance threshold.
Results. In patients with HV, the N/L index was 3.29±0.40. It was slightly higher than in SP (3.48±0.53 vs 2.69±0.34; p>0.05). The N/L index exceeded 3.3 was determined in 38.71% and >3.5 – in 22.6 of HV patients with SP. Such patients had worse structural and functional parameters of the heart. According to the correlation analysis, an increase in the N/L index >3.3–3.5 was associated with hypertrophy and dilatation of the ventricles with stretching of the valves and development of dysfunction, activation of neutrophilic inflammation, and suppression of the immune cellular component.
It has been established that an increase in the N/L index can be not only a prognostic sign of gastrointestinal and renal lesions, but also a sign of heart changes – hypertrophy and dilatation with impaired systolic and diastolic functions.
Conclusion. The ratio of neutrophilic granulocytes to lymphocytes is a simple and informative indicator of the activity of inflammation which is easily calculated in practice and is associated with the structural and functional changes in heart in patients with hemorrhagic vasculitis and hepatic steatosis.

Abstract
Neutrophil to lymphocyte ratio has been examined among several studies regarding Henoch Schonlein purpura patients with gastrointestinal involvement. The current meta-analysis aims to evaluate neutrophil to lymphocyte ratio differences between Henoch Schonlein purpura patients with and without gastrointestinal manifestations.An extensive search of the available literature was done using MEDLINE (1966-2020), Clinicaltrials.gov (2008-2020), Cochrane Central Register of Controlled Trials (CENTRAL) (1999-2020) and Google Scholar (2004-2020) databases and statistical analysis was mainly conducted using RevMan 5.3 software.The current meta-analysis is based on data from six studies. Neutrophil to lymphocyte ratio was higher in Henoch Schonlein patients with gastrointestinal involvement than those without with a mean difference of 0.88 (95% confidence interval [CI]: 0.55, 1.22 [P < 10-5, I2 = 8%]). Low heterogeneity (I2) was observed between the included studies. Subgroup analysis, leave one out meta-analysis and meta-regression analysis were performed which led to the lowering of I2 to 0.The findings of our meta-analysis suggest that the neutrophil to lymphocyte ratio could serve as a marker of gastrointestinal involvement in patients with Henoch Schonlein purpura; however, most of the included studies are case-control, therefore future cohort studies should clarify the value of this marker.

Abstract
OBJECTIVE Although relatively rare, adult immunoglobulin A vasculitis (IgAV) can lead to severe complications and longer hospitalization, and result in poor prognosis, when compared to childhood IgAV. Hence, early identification and prevention for patients prone to develop systemic involvement are essential. The purpose of this study was to explore the correlations of common serological markers with the development of systemic involvement in adult IgAV. METHODS A retrospective analysis was performed for adult IgAV patients, who were hospitalized in Wuhan Union Hospital between January 2016 and December 2019. A total of 259 patients were enrolled, and the pre-treatment serological markers were comprehensively assessed. RESULTS In the present study, 49.0% and 33.2% of patients developed renal and gastrointestinal (GI) involvement, respectively. Furthermore, the elevated levels of white blood cells count, D-Dimer (D-D), C-reactive protein (CRP) and neutrophil granulocyte ratio (NE%) >60% were significantly associated with GI involvement in the univariate analysis, while the decrease in high density lipoprotein level, and the elevated D-D and CRP levels were significantly associated with renal involvement (P<0.05). Moreover, a prediction model that combined multiple markers was established by performing a logistic regression analysis, and this presented a more favorable value of prediction than the individual serological markers. CONCLUSION The present study suggests that common serological markers have close correlations with systemic involvement in adult IgAV, and that the establishment of a prediction model for systemic involvement may be helpful in facilitating personalized therapeutic strategies and clinical management for IgAV patients.

Abstract
The diagnosis of elderly-onset IgA vasculitis (IgAV) and its prognosis can be difficult to ascertain because of its rarity and the frequent presence of comorbidities. Furthermore, the treatment of elderly-onset IgAV remains controversial. We report a case of IgAV in an 87-year-old patient. Renal involvement was detected early during the IgAV follow-up. He was treated with low-dose corticosteroid and azathioprine, which led to a complete remission without any adverse effects. This suggests that precise intervention with early diagnosis and careful renal follow-up may prevent renal failure and that low-dose steroids with azathioprine can be an effective treatment for elderly-onset IgAV with nephritis.

Abstract
Purpose To describe a case series of scleritis associated with IgA vasculitis (IgAV) at a tertiary referral center. Observations Three men with scleritis associated with IgAV were identified: one with anterior scleritis alone, one with anterior scleritis and peripheral ulcerative keratitis (sclerokeratitis), and one with anterior and posterior scleritis. Visual acuity was preserved except from the patient who developed posterior scleritis. Ocular pain was the main symptom at presentation. All patients had a previous history of palpable purpura, but only one was aware of his underlying IgAV. Laboratory results revealed microhematuria and proteinuria with normal urinary β2 microglobulin levels and negative serum ANCAs. Skin or kidney biopsy demonstrated leukocytoclastic vasculitis or glomerulonephritis with dominant IgA immune deposits. Conclusions and Importance Although uncommon, IgAV should be included in the differential diagnosis of anterior scleritis alone or associated with peripheral ulcerative keratitis or posterior scleritis, even in systemically asymptomatic patients. Urinalysis should not be underestimated in assessment of scleritis to detect early stages of glomerular disease. Scleritis may be the first manifestation whose study may lead to the diagnosis of IgAV. Multidisciplinary approach is necessary to prevent irreversible organ damage such as renal failure.

Abstract
OBJECTIVE The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are associated with the severity of Henoch-Schonlein purpura (HSP). Therefore, we conducted a meta-analysis to evaluate the clinical significance of NLR and PLR in HSP and its complications. METHODS A comprehensive literature search was conducted by searching the PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang, VIP, and SinoMed databases from their inception to September 31, 2020. We used the standard mean difference (SMD) with a 95% confidence interval (CI) to estimate the pooled effect and used subgroup analysis to investigate heterogeneity. RESULTS A total of 1,691 HSP patients and 563 healthy controls (HCs) from 15 studies were included in the analysis. The NLR value was significantly higher in 431 HSP patients with gastrointestinal complications (HSP-GCs) than that in 833 HSP patients without GCs (SMD = 1.09, 95% CI: 0.62-1.57, P < 0.001); in 83 HSP adult patients with renal involvement (HSP-RI) than that in 131 adult HSP patients without RI (SMD = 0.33, 95% CI: 0.05-0.60, P = 0.021); and in 831 HSP patients than that in 563 HCs (SMD = 0.70, 95% CI: 0.51-0.89, P < 0.001). The PLR was significantly higher in 417 HSP patients than that in 264 HCs (SMD = 0.39, 95% CI: 0.06-0.71, P = 0.02). CONCLUSIONS NLR could serve as a useful biomarker to predict GCs and RI in patients with HSP. However, further well-designed and large cohort studies are warranted to confirm these findings.

Abstract
OBJECTIVES Immunoglobulin A vasculitis (IgAV) is a small-vessel vasculitis most frequently benign in children while the disease is more severe in adults. We aimed to study the impact of age on presentation and outcome of adult IgAV. METHODS We conducted a nationwide retrospective study including 260 IgAV patients. Patients were divided into four quartiles according to the age at IgAV diagnosis: <36; 36≤age < 52; 52≤age < 63 and ≥63 years. Comparison of presentation and outcome were performed according to age of disease onset. RESULTS Mean age at diagnosis was 50.1 ± 18 years and 63% were male. IgAV diagnosed in the lowest quartile of age was associated with more frequent joint (p< 0.0001) and gastrointestinal involvement (p= 0.001). In contrast, the oldest patients had more severe purpura with necrotic lesions (p= 0.001) and more frequent renal involvement (p< 0.0001), with more frequent hematuria, renal failure, higher urine protein excretion and more frequent tubulointerstitial lesions. Patients were treated similarly in all groups of age, and clinical response and relapse rates were similar between groups. In the 127 treated patients with follow-up data for >6 months, clinical response and relapse rates were similar between the four groups. Median follow-up was of 17.2 months (9.1-38.3 months). Renal failure at the end of follow-up was significantly more frequent in the highest quartile of age (p= 0.02), but the occurrence of end-stage renal disease was similar in all groups. Last, overall and IgAV-related deaths were associated with increase age. CONCLUSION Aging negatively impacts the severity and outcome of IgAV in adults. Younger patients have more frequent joint and gastrointestinal involvement, while old patients display more frequent severe purpura and glomerulonephritis.

Abstract
BACKGROUND IgA nephropathy (IgAN) is achronic immuno-inflammatory progressive disease. Several systemic inflammatory indicators, mainly the neutrophil-to-lymphocyte ratio (NLR), are regarded as valuable markers for many diseases, such as IgA vasculitis and chronic kidney disease. Here, we investigated multiple peripheral blood indicators in a large IgAN registry with regular follow-up to evaluate their effects on IgAN phenotypes and progression. METHODS Totally, 1151 IgAN patients with regular follow-up, and 251 healthy volunteers were enrolled. Complete blood count test results, including counts of white blood cells (WBC), neutrophils (NE), lymphocyte (LY), and platelets (PLT), were collected from medical records. Then, NLR and PLR were calculated. RESULTS IgAN patients presented with increased WBC, NE, NLR and PLR levels and decreased LY levels compared with controls. In univariate survival analysis, WBC, NE and NLR showed significant associations with IgAN progression, and NLR had a higher area under the ROC curves than NE and WBC. When adjusted for well-known risk factors, NLR remained an independent risk factor for poor renal outcome in IgAN patients and performed better than NE. By using NLR 2.40 as cutoff point, IgAN patients were divided into two groups. IgAN patients in the high NLR group presented with lower eGFR, higher proteinuria, higher incidence of hypertension, and more severe pathological lesions, as well as lower event-free renal survival rate. CONCLUSIONS We found patients with IgAN had elevated NLR levels than healthy controls, and the easily available NLR in clinical practice could serve as an independent risk factor for IgAN progression.
