Abstract
PURPOSE Autoimmune bullous diseases, connective tissue diseases, and vasculitis represent a group of severe rare skin diseases. While glucocorticoids and immunosuppressive agents serve as standard treatments for these diseases, their efficacy is limited due to adverse side effects, indicating the need for alternative approaches. Biologics have been used in the management of some rare skin diseases. However, the use of biologics is associated with concerns, such as infection risk and high costs, prompting the quest for efficacious and cost-effective alternatives. This study discusses the safety issues associated with tofacitinib and its potential in treating rare skin diseases. METHODS This narrative review focuses on the pharmacodynamic properties of tofacitinib and its impact on the JAK/STAT pathway. In addition, we present a comprehensive discussion of the effects and mechanism of action of tofacitinib for each severe rare skin disease. RESULTS This role of tofacitinib in treating severe rare skin diseases has been discussed, shedding light on its promising prospects as a treatment modality. Few reports of serious adverse events are available in patients treated with tofacitinib. CONCLUSION We explored the mechanism of action, efficacy, and safety considerations of tofacitinib and found that it can be used as a treatment option for rare skin diseases. However, multicenter clinical studies are needed to confirm the efficacy and safety of JAK inhibitors.

Abstract
Background IgA vasculitis (IgAV) is an immune-associated vasculitis, yet its exact etiology remains unclear. Here, we explore the interaction between IgAV and inflammatory factors using bidirectional Mendelian randomization (MR). Methods We conducted a bidirectional summary-level MR analysis to delineate the causality of C-reactive protein (CRP), procalcitonin (PCT), and 41 circulating inflammatory regulators with IgAV. Data on genetic variants related to inflammation were obtained from three genome-wide association studies (GWASs) on CRP, PCT, and human cytokines, whereas data on IgAV was from large meta-analyses of GWAS among 216 569 FinnGen Biobank participants. The primary MR analysis was performed using the inverse-variance weighted (IVW) approach, and the sensitivity analyses were carried out using MR-Egger, weighted median, weighted mode, and MR-pleiotropy residual sum and outlier. Results This study revealed the association of CRP higher levels with increased risk of IgAV through IVW method (Estimate odds ratio [OR] = 1.41, 95% confidence interval [CI]: 1.01-1.98, P = 0.04), MR-Egger (OR = 1.87, CI: 1.15-3.02, P = 0.01), weighted median (OR = 2.00, CI: 1.21-3.30, P = 0.01) and weighted mode (OR = 1.74, CI: 1.13-2.68, P = 0.02). Furthermore, elevated IL-8 was strongly implicated with a higher risk of IgAV (IVW OR = 1.42, CI: 1.05-1.92; P = 0.02). Conversely, genetically predicted IgAV was associated with decreased levels of TNF-β (IVW estimate β = -0.093, CI: -0.178 - -0.007; P = 0.033). Additionally, no such significant statistical differences for other inflammatory factors were found. Conclusion Our current study using bidirectional MR analysis provides compelling evidence for a causal effect of CRP, PCT, and circulating inflammatory regulators on IgAV. These findings contribute to a better understanding of the pathogenesis of IgAV and emphasize the potential of targeting inflammatory factors for therapeutic interventions.

Abstract
Introduction SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome is a rare disease clinically characterized by a wide range of cutaneous and osteoarticular manifestations, involving multiple system impairments. Vasculitis is a rare comorbidity of SAPHO. Henoch-Schönlein purpura (HSP) is a vasculitis involving the capillaries and arterioles mediated by IgA immune complex. No case report of SAPHO syndrome with HSP was ever found. Case Here we reported a case of SAPHO syndrome complicated with HSP and was successfully treated by methylprednisolone and tofacitinib. Discussion Although the treat-to-target management of HSP and the first-line clinical medication have given some advices on the treatment. A precise treatment was still needed based on the pathogenesis of the comorbidity. The mechanism of the co-occurrence includes innate immunity and adapted immunity. Considering the active inflammatory reaction and the rapid disease progression, methylprednisolone and tofacitinib were prescribed. Conclusion HSP is a new comorbidity of SAPHO. The spectrum of cutaneous small-vessel vasculitis in SAPHO syndrome was enriched. A new treatment approach for SAPHO with HSP was provided.

Abstract
The clinical characteristics and risk factors for testicular/epididymal involvement in 73 children with immunoglobulin A vasculitis (IgAV) who were admitted to our hospital between January 2012 and November 2022 were reviewed. The demographic data, laboratory parameters, and follow-up data of the patients were compared to those of 146 males without testicular/epididymal involvement. A logistic regression analysis was performed to determine the variables associated with testicular/epididymal involvement. The prevalence of testicular/epididymal involvement among male patients with IgAV was 1.3% (73/5,556). Increased blood flow in the testes and/or epididymis on ultrasound was found in 71 patients. The remaining two patients underwent surgical exploration for loss or reduction of testicular blood flow. One patient underwent orchiectomy for intraoperative confirmation of complete right testicular infarction. Pathological findings revealed IgA immune complex deposition in the testis. Patient age (odds ratio [OR] = 0.792; 95% confidence interval [CI]: 0.682-0.919, p = 0.002), platelet count (OR = 1.011; 95% CI: 1.002-1.020, p = 0.013), and immunoglobulin M (IgM) levels (OR = 0.236; 95% CI: 0.091-0.608, p = 0.003) were strongly associated with the occurrence of testicular/epididymal involvement in IgAV. Therefore, young age, increased platelet count, and low IgM levels in patients with IgAV are potential risk factors for testicular/epididymal involvement. Doppler ultrasound can help differentiate IgAV from acute scrotum. Most patients with testicular/epididymal involvement have good prognoses, although serious complications such as testicular infarction may occur.

Abstract
IgA, previously called Henoch-Schönlein vasculitis, is an essential immune component that drives the host immune response to the external environment. As IgA has the unique characteristic of a flexible response to broad types of microorganisms, it sometimes causes an autoreactive response in the host human body. IgA vasculitis and related organ dysfunction are representative IgA-mediated autoimmune diseases; bacterial and viral infections often trigger IgA vasculitis. Recent drug developments and the presence of COVID-19 have revealed that these agents can also trigger IgA vasculitis. These findings provide a novel understanding of the pathogenesis of IgA vasculitis. In this review, we focus on the characteristics of IgA and symptoms of IgA vasculitis and other organ dysfunction. We also mention the therapeutic approach, biomarkers, novel triggers for IgA vasculitis, and epigenetic modifications in patients with IgA vasculitis.

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
BACKGROUND To explore the changes of inflammatory and oxidative stress responses in Henoch-Schönlein purpura (HSP) children, and further analyzed the therapeutic effects and mechanisms of hemoperfusion (HP) on HSP with severe gastrointestinal (GI) involvement. METHODS There were 200 children with HSP were divided into three groups according to their clinical manifestations: 60 in HSP without GI and renal involvement group, 60 in HSP with GI involvement group, and 80 in HSPN group. The HSP with GI involvement group was subdivided into conventional treatment (n = 30) and HP (n = 30) groups. Thirty children who visited the department of children healthcare for healthy physical examinations from January to December 2017 were set as healthy control group. The IL-6 and TNF-α levels were detected by chemoluminescence method. The MDA, SOD and T-AOC levels were determined by thiobarbituric acid colorimetric method, hydroxylamine method and chemical colorimetry. RESULTS Compared with healthy group, IL-6, TNF-α and MDA levels in HSP were increased in each group, while SOD and T-AOC were decreased (P = 0.000). IL-6, TNF-α and MDA levels in the HSPN group were the highest, SOD and T-AOC levels were the lowest (P = 0.000). Compared with those before treatment, IL-6, TNF-α and MDA levels in the conventional and HP groups were decreased and SOD and T-AOC levels were increased (P = 0.000). The changes in HP group were more significant than those in conventional group (P < 0.047). Compared with conventional group, glucocorticoid dosage and the occurrence rate of hematuria and/or proteinuria within 3 months were lower in HP group. (P = 0.000, 0.004). CONCLUSIONS Inflammatory and oxidative stress may be involved in the acute phase of HSP children. The intensity of inflammatory and oxidative stress responses were related to the degree of renal involvement. HP can reduce glucocorticoid dosage and the rate of renal involvement in children with severe HSP with GI involvement. The mechanism may be related to the fact that HP can effectively remove IL-6, TNF-α, MDA in HSP children.

Abstract
Background Henoch-Schönlein purpura, more recently renamed immunoglobulin A vasculitis (IgAV), is a systemic vasculitis characterized by IgA deposits. The current markers used to assess IgAV inaccurately evaluate the risk of nephritis occurrence and its long-term outcomes. The current study assessed biomarkers of nephritis outcomes. Methods This French multicentre prospective study enrolled 85 adult patients at the time of disease onset. Patients were assessed for clinical and biological parameters and re-examined after 1 year. Immunoglobulins, cytokines, IgA glycosylation, IgA complexes and neutrophil gelatinase-associated lipocalin (NGAL) concentrations were assessed in blood and urine. Results We identified 60 patients with IgAV-related nephritis (IgAV-N) and 25 patients without nephritis (IgAV-woN). At the time of inclusion (Day 1), the serum levels of galactose-deficient IgA1 (Gd-IgA1) and urinary concentrations of IgA, IgG, IgM, NGAL, interleukin (IL)-1β, IL-6, IL-8, IL-10, IgA-IgG and IgA-sCD89 complexes were higher in the IgAV-N patients than in the IgAV-woN patients (P < 0.005 for all comparisons). After follow-up (1 year), 22 patients showed a poor outcome. Among the tested markers, urine IgA at disease onset adequately reclassified the risk of poor outcome over conventional clinical factors, including estimated glomerular filtration rate, proteinuria and age (continuous net reclassification improvement = 0.72, P = 0.001; integrated discrimination improvement = 0.13, P = 0.009) in IgAV patients. Conclusions Taken together, these results showed that serum Gd-IgA1 and urinary IgA, IgG, IgM, NGAL, IL-1β, IL-6, IL-8, IL-10, IgA-IgG and IgA-sCD89 complexes were associated with nephritis in IgAV patients. Urinary IgA level may improve patient risk stratification for poor outcome.

Abstract
AIMS IgA vasculitis (IgAV) is a common small-vessel systemic vasculitisthat is histologically characterised by granulocyte infiltration and IgA deposition in vessel walls. Information on microRNA (miRNA) involvement inIgAVis limited. The aim of this study was to analyse the association between histopathological changes and expression profiles of 14 miRNAs in the affected skin of 70 adult patients with IgAV. METHODS AND RESULTS miRNA expression analysis was performed by quantitative real-time polymerase chain reaction and evaluation of histopathological changes by light and immunofluorescence microscopy on formalin-fixed paraffin-embedded skin excision samples. In IgAV-affected skin, granulocyte infiltration was significantly associated with vessel fibrinoid necrosis. Of the analysed miRNAs, four showed two-fold increased expression (let-7d, let-7f, miR-21-5p, and miR-203-3p), five showed five-fold increased expression (let-7b, miR-17-5p, miR-155-5p, miR-423-5p, and miR-451a), and threeshowed 15-fold increased expression (let-7a, miR-21-3p, miR-223-3p), as compared with controls (all P < 0.001). miR-146a-5p and miR-148b-3p showed three-fold decreased expression (P = 0.981 and P < 0.001). The expression of miR-223-3p also showed a significant positive association with granulocyte infiltration and fibrinoid necrosis. CONCLUSIONS Altered miRNA expression, especially of miRNA-223-3p, may be associated with the skin inflammatory state in IgAV. The majority of aberrantly expressed miRNAs in IgAV-affected skin are known to influence the nuclear factor-κB signalling pathway, which is crucial for activation of key proinflammatory genes, including those encoding tumour necrosis factor-α, interleukin (IL)-6, and IL-8. Furthermore, miR-146a-5p and miR-148b-3p, which are negative regulators of inflammatory gene expression, showed decreased expression and could contribute to the exaggerated inflammation. Further investigation of miRNA expression in the affected tissues could improve our knowledge of IgAV pathogenesis, and possibly help to identify novel biomarkers in body fluids.

Abstract
The pathogenesis of the immunoglobulin A vasculitis (IgAV) is still unknown. The available data shows that interleukin (IL)-17, IL-18, IL-23, regulated on activation, normal T cell expressed and secreted (CCL 5, RANTES), and interferon (IFN)-γ-inducible protein 10 (IP10) participate in the pathogenesis of IgAV by influencing the recruitment of leukocytes to the site of inflammation. The aim of this study was to analyze the serum concentration of IL-17A, IL-18, IL-23, RANTES, and IP10 in patients with acute IgAV compared to healthy children. Moreover, we wanted to assess the suitability of the levels of tested cytokines to predict the severity of the disease. All children with IgAV hospitalized in our institution between 2012 and 2017 were included in the study. Cytokines levels were determined in a serum sample secured at admission to the hospital. Basic laboratory tests have also been analyzed. IL-17A, IL-18, and IL-23 were significantly higher in whole IgAV group (52.25 pg/ml; 164.1 pg/ml and 700 pg/ml, respectively) than in the control group (27.92 pg/ml; 140.1 pg/ml and 581.5 pg/ml, respectively). The receiver operating characteristic (ROC) curve analysis revealed the largest area under the curve (AUC 0.979, p < 0.001) for the IL-17A with 95.1% sensitivity and 91.7% specificity. There were no significant differences in cytokine levels depending on the severity of the IgAV. Although the serum levels of the IL-17A, IL-18, and IL-23 increase significantly in the acute phase of the IgAV, they cannot be used as indicators of predicting the course of the disease. IL-17A seems to be a good predictor of IgAV occurrences.

Abstract
Immunoglobulin A vasculitis (IgAV) is an immune complex, small vessel vasculitis with dominant IgA deposits in vessel walls, predominantly affecting the pediatric population. However, adults frequently have more severe gastrointestinal tract (GIT) and renal involvements as compared to children. Our aim was to study serological and cellular biomarkers to support clinicians in their diagnosis and the course of IgAV in adult patients. This cross-sectional study included 62 adult IgAV patients and 53 healthy blood donors (HBDs). Demographic and clinical data, as well as routine laboratory tests, were meticulously analyzed. Serum levels of IL-1β, IL-2, IL-6, IL-8, IL-9, IL-10, IL-17A, IL-23, TNF-α and serum amyloid A (SAA) were measured. Percentages of neutrophils, lymphocytes, and monocytes with neutrophil expression of L-selectin and integrin αM were determined by flow cytometry. SAA (12-fold), IL-6 (3-fold), IL-8 (2-fold), and TNF-α (2-fold) were significantly elevated in sera of adult IgAV patients compared to HBDs. There was a 16% elevation in neutrophils in IgAV patients, with IgAV neutrophils showing significantly higher CD62L surface expression. IgAV patients with GIT involvement exhibited elevated numbers of leukocytes, neutrophils, and neutrophil/lymphocyte (NLR), but lower neutrophil CD11b expression, as compared to IgAV patients without GIT. IgAV patients exhibit a low-medium grade inflammatory, neutrophil-driven response. Patients with GIT can be distinguished by their elevated NLR.

Abstract
We evaluated the occurrence of antiphospholipid antibodies (aPLs) in acute adult IgA vasculitis (IgAV), and potential correlations with IgAV clinical presentation. We determined lupus anticoagulants (LAs) and IgG, IgM, and IgA isotypes of anticardiolipin antibodies (aCL), antibodies against β2-glycoprotein I (aβ2GPI) and against the phosphatidylserine-prothrombin complex (aPS/PT) in prospectively collected, histologically proven IgAV, diagnosed for the first time between January 2013 and February 2018 at our secondary/tertiary rheumatology center. During the 62 months, we determined aPLs in 125 IgAV patients (56.8% male; median (IQR) age 64.7 (48.6-78.2) years). Sixty-four (51.2%) patients had aPLs. We found LAs, aPS/PT, aβ2GPI, and aCL in 24.8%, 21.6%, 13.6%, and 11.2% of cases, respectively. With 17.6%, the IgA aPS/PT was the most common aPL subtype. aPL-positive and aPL-negative patients did not differ in the clinical presentation of acute IgAV or in the frequency of thrombotic events. aPL-positive IgAV patients had significantly higher erythrocyte sedimentation rate (p < 0.001), and C-reactive protein (p < 0.001). The subset of IgA aPS/PT-positive patients more commonly had renal involvement in acute disease (RR 2.4 (95% CI 1.6-3.7)). aPLs are commonly detected during acute IgAV episodes. Patients with aPLs have similar clinical presentation, but higher markers of inflammation at than those without them. The subset of IgAV patients with IgA aPS/PT more commonly had renal involvement.

Abstract
The changes of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-10 (IL-10) in the serum of Henoch-Schonlein purpura nephritis (HSPN) patients were analyzed to explore the correlation between the above inflammatory factors and progression of the disease. The present study used the double antibody sandwich enzyme-linked immunosorbent assay (ELISA) method to detect the serum levels of TNF-α, IL-8, IL-10 and urine protein in 112 cases of patients with Henoch-Schonlein purpura (HSP), including 54 cases of HSP combined with renal function impairment (group HSPN), and 58 cases not combined with renal function impairment (NHSPN), as well as 50 healthy patients who were selected as the control group. The concentration of TNF-α, IL-8, and IL-10 in the serum of HSP patients were higher than that of the control group, and the difference was statistically significant (P<0.05). There was no significant difference in the levels of IL-10, and IL-8 between the HSPN group and the NHSPN group (P>0.05), but the level of TNF-α in the serum of HSPN group was significantly higher than that of NHSPN group (P<0.05). TNF-α, IL-8 and IL-10 levels of the acute nephritis, chronic nephritis and nephrotic syndrome groups were all higher than the simple proteinuria group. In addition, the levels of the three factors of the acute nephritis group were all higher than those of the chronic nephritis and nephrotic syndrome groups (P<0.05). IL-8, IL-10, and TNF-α were positively correlated with the urinary protein levels. The results indicated that the levels of serum TNF-α, IL-8 and IL-10 are correlated with HSPN, and serum TNF-α concentration can be used as an indicator of the severity of HSPN.

Abstract
Henoch–Schönlein purpura is a systemic vasculitis characterized by IgA deposits, which target the skin, joints, and kidneys, among other organs. In children, prognosis is often good but little is known about biomarkers of pediatric nephritis. We hypothesized that biological markers, including cytokines, immunoglobulins, IgA-immune complexes, IgA glycosylation and neutrophil gelatinase-associated lipocalin (NGAL), may discriminate IgA vasculitis (IgAV) pediatric patients with renal involvement from those without renal involvement. Fifty children at the time of IgAV rash between 2010 and 2015 were prospectively enrolled and compared to 21 controls. All patients were assessed for clinical and biological parameters at the time of diagnosis, including the levels of cytokines, immunoglobulins, immune complexes, IgA glycosylation and NGAL in serum and urine. Among IgAV patients, 33 patients exhibited nephritis (IgAV-N) and 17 children were without nephritis (IgAV-woN). The serum level of galactose-deficient (Gd)-IgA1 (p<0.01) and the urinary concentrations of IgA, IgG, IgM, IL-6, IL-8, IL-10, IgA-IgG complexes and IgA-sCD89 complexes (p<0.001 for all) were higher in the IgAV-N patients than in the IgAV-woN patients. Among those markers, urinary IgA and IgM had the highest AUC (0.86 and 0.87 respectively, p<0.0001). This prospective cohort study furthers our understanding of the pathophysiology of IgAV. We identified biomarkers that are able to distinguish patients initially with or without nephritis. To conclude, serum Gd-IgA1 and urinary IgA, IgG, IgM, IL-6, IL-8, IL-10, and IgA-IgG and IgA-sCD89 complexes could identify IgAV pediatric patients with renal involvement at the time of diagnosis.

Abstract
Background Henoch-Schonlein purpura is a systemic small-vessel vasculitis that occurs mainly in children. A review of the literature has suggested a correlation between mean platelet volume and several inflammatory disorders. However, to the best of our knowledge, any potential correlation between mean platelet volume and Henoch-Schonlein purpura has not been reported in the literature. Therefore, our study aimed to evaluate the role of mean platelet volume concentrations in patients with Henoch-Schonlein purpura. Methods This study included 97 children with Henoch-Schonlein purpura and 120 healthy individuals as controls. Results Mean platelet volume concentrations were found to be significantly lower in Henoch-Schonlein purpura patients compared with healthy controls (8.1 ± 0.86 vs. 9.4 ± 0.81, P < 0.001). Similarly, significant negative correlations were observed between mean platelet volume and neutrophil count, platelet count and erythrocyte sedimentation rate in patients with Henoch-Schonlein purpura (r=−0.327, P = 0.001; r=−0.419, P < 0.001; r=−0.255, P = 0.012). Interestingly, mean platelet volume was significantly lower in the acute phase compared with the convalescent phase of Henoch-Schonlein purpura patients (7.8 ± 0.86 vs. 8.3 ± 0.77, P = 0.002). A cut-off value for mean platelet volume was 7.85 with area under the curve of 0.726 to identify acute phase vs. convalescent phase in patients with Henoch-Schonlein purpura. Mean platelet volume was independently associated with Henoch-Schonlein purpura in logistic regression analysis (odds ratio = 0.114, 95% confidence interval = 0.053–0.243, P < 0.001). Conclusions Our results suggest that mean platelet volume is inversely associated with disease in patients with Henoch-Schonlein purpura, and mean platelet volume may be a useful marker to identify active disease in Henoch-Schonlein purpura patients.

Abstract
Henoch-Schönlein Purpura (HSP, IgA vasculitis) is an immunoglobulin A (IgA) mediated disorder characterized by systemic vasculitis with variable presentation, frequently affecting the skin, mucous membrane, joints, kidneys, and rarely lungs and the central nervous system. Interestingly, enhanced production of interleukin-8 (IL-8) levels are found during active disease and increased levels have been reported in supernatants from human umbilical venous endothelial cells after stimulation with sera from patients affected by HSP. While corticosteroid therapy is currently the recommended treatment for HSP, dapsone, an anti-leprosy agent, has also recently been suggested to have therapeutic efficacy due to its ability to suppress IL-8. Moreover, in addition to IL-8 suppression, dapsone has been reported to exert various anti-inflammatory effects by inhibiting the generation of toxic free radicals, myeloperoxidase mediated halogenation that converts H2O2 to HOCl, leukocyte chemotaxis, production of tumor necrosis factor, and other anti-inflammatory molecules. This review aims to provide a solid hypothesis for the pathogenesis of vasculitis in HSP. Moreover, we highlight potential mechanistic actions of dapsone in hopes that dapsone may be considered as an alternative viable treatment for patients affected by HSP.

Abstract
Immunoglobulin A (IgA) vasculitis is a form of leukocytoclastic vasculitis of small vessels, clinically characterized by purpuric skin lesions unrelated to any underlying coagulopathy, gastrointestinal manifestations, arthritis and/or arthralgia and renal involvement. The etiology remains unknown, but various triggers including infections, vaccination, drugs and malignancy have been hypothesized to be associated with the development of IgA vasculitis. Although the pathogenesis has not been completely figured out, genetic predisposition, aberrant glycosylation of the hinge region of IgA1, activated complements, cytokines and chemokines were put out to play important roles in the immunopathogenesis of IgA vasculitis. Histologically, the infiltration of small blood vessels with polymorphonuclear leukocytes and the presence of leukocytoclasia are typical pathologic findings in IgA vasculitis. The treatment is usually supportive, and advanced treatments include immunosuppressive drugs (glucocorticoids and immunosuppressive agents), hemopurification and surgery. The prognosis depends on the age at the disease onset and the renal involvement or not.
