[PMID: 36107741 DOI: 10.1093/mr/roac111] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 07/18/2022] [Accepted: 09/12/2022] [Indexed: 08/27/2023]
Abstract
OBJECTIVES Immunoglobulin (Ig) A vasculitis (IgAV), is the most common vasculitis of childhood, is a leucocytoclastic vasculitis that affects small vessels of the skin, gastrointestinal (GI) tract, joints, and kidneys. Scrotal involvement is relatively rare. In this study, we aimed to reveal the clinical and laboratory characteristics of patients with scrotal involvement in IgAV and its relationship with other clinical features of the disease. METHODS A total number of 301 male patients with a diagnosis of IgAV between January 2005 and 2022 were retrospectively analysed. The patients were divided into two groups as with and without scrotal involvement. The clinical and laboratory characteristics of the groups were compared. RESULTS Scrotal involvement was detected in 16.3% (49) of male IgAV patients. Scrotal involvement was unilateral in 51% of patients. While single acute scrotal attack was present in 93.9% of patients, only three patients had recurrent acute scrotal involvement. In patients with scrotal involvement, the age at diagnosis was younger (p = .007), and disease recurrence was higher (p = .003). Glucocorticoid use was more common in patients with scrotal involvement (p < .001). In multivariable analysis, a statistically significant relation between scrotal involvement and age at diagnosis (odds ratio = 0.85, 95% confidence interval 0.76-0.96, p = .006) was detected. CONCLUSIONS In IgAV patients with scrotal involvement, the age at diagnosis is lower, steroid use is more common, and recurrent disease is more frequent.

Abstract
OBJECTIVES To describe venous sinus thrombosis involved in immunoglobulin A (IgA) vasculitis and identify the clinical features and imaging findings of this rare disease. METHODS We describe a case with venous sinus thrombosis related to IgA vasculitis, and a systematic review of previously reported cases in the literature. RESULTS A 10-year-old boy presented with recurrent petechiae of the lower extremities with abdominal pain, and was diagnosed as having IgA vasculitis. He had a sudden headache during the treatment of steroids, and venous sinus thrombosis was diagnosed according to magnetic resonance imaging. Venous sinus thrombosis is a rare complication of IgA vasculitis. Based on the systematic review, most of these reported cases who developed venous sinus thrombosis had multi-system involvement, which included skin, joints, gastrointestinal tract or kidneys. Sudden headache was the most common symptom of central venous sinus thrombosis. Some cases may also manifest as seizures and blindness. The sagittal sinus was the most common site of thrombosis. Magnetic resonance image, magnetic resonance venography, or computed tomography angiography were helpful for early diagnosis of this disease. Combination therapy of steroids and anticoagulation medication was effective in rapidly reliving clinical symptoms. CONCLUSIONS Sudden headache in patients with IgA vasculitis requires vigilance for the possibility of central venous sinus thrombosis. Anti-inflammatories combined with anticoagulant therapy were needed for these patients.

Abstract
Henoch-Schönlein purpura (HSP) is the most common vasculitis in childhood, presenting with purpura, predominantly of the lower extremities and occasionally with renal involvement as well. Although associated with childhood, HSP, although rarely, can also develop in adults as well. Here we present a patient in his sixties, presenting with a myriad of rash units on his lower extremities, including bullous ones, and a constellation of chronic kidney failure. Skin and renal biopsy specimens revealed morphological changes and immune depositions representative of HSP. Despite treatment, the patient's kidney failure slowly progressed, and he expired eight months after his presentation due to associated complications. Although rare, the bullous form of HSP can be viewed as a more aggressive form of the disease, as seen by the presentation constellation and rapid progression in our case.

Abstract
PURPOSE OF REVIEW This review paper evaluates the use of patient reported outcome (PROs) in systemic vasculitis and the increasing incorporation of these measures in the evaluation of clinical outcomes and healthcare provision. RECENT FINDINGS Generic PROs such as the SF-12, SF-36, EQ-5D have been used to evaluate health-related quality of life (HRQOL) across the spectrum of vasculitis; including giant cell arteritis, antineutrophil cytoplasmic antibody (ANCA)-related vasculitis and immunoglobulin A vasculitis (IgA) vasculitis. More recently disease-specific PROs have been developed including the associated vasculitis (AAV)-PRO and GCA-PRO, whilst further work is ongoing including a Steroid-PRO. SUMMARY Generic and disease-specific PROs are complimentary in nature, but the advent of disease-specific PROs allows evaluation of the impact of specific symptoms and intervention on patient HRQOL. Following the COVID-19 pandemic, the advent of increasing virtual work has brought the potential for electronic-PRO measures to the forefront and is a current area of interest.

Abstract
OBJECTIVE Henoch-Schönlein purpura is a systemic vasculitis that mainly occurs in children. Renal impairment is a major complication of Henoch-Schönlein purpura, but there is no established predictive marker for renal involvement. Thus, in this study, we investigated the risk factors for renal involvement in children with Henoch-Schönlein purpura. METHOD The medical records of children newly diagnosed as having Henoch-Schönlein purpura between 2005 and 2020 were reviewed retrospectively. Selected laboratory data were recorded before treatment initiation. The date and the age at diagnosis; sex; and the presence of arthralgia, gastrointestinal and renal involvement were obtained retrospectively. RESULTS This study included a total of 186 patients with Henoch-Schönlein purpura. Among them, 36.0% had renal involvement; 28.4% had only microscopic hematuria, 53.7% had non-nephrotic range proteinuria, and 17.9% had nephrotic-range proteinuria during follow-up. The mean age was higher (p = 0.016) and female sex was predominant (p = 0.001) in patients with renal involvement than in those without renal involvement. Blood neutrophil/lymphocyte ratio (p = 0.002) and platelet/lymphocyte ratio (p = 0.002) were significantly higher than that of the patients without renal involvement. No statistically significant differences were observed in the hemoglobin concentration, platelet count, presence of arthralgia, and gastrointestinal involvement between patients with and without renal involvement. Logistic regression analysis revealed female sex (odd ratio = 3.213) and neutrophil/lymphocyte ratio (odd ratio = 1.329) as risk factors for renal involvement. CONCLUSIONS Female sex and high neutrophil/lymphocyte ratio were risk factors for renal involvement in Henoch-Schönlein purpura.

Abstract
BACKGROUND Henoch-Schönlein purpura (HSP), also called IgA vasculitis, is a systemic vasculitis characterized by deposits of immunoglobulin A in blood vessels. Renal impairment of these patients is the main determinant of prognosis. The optimal treatment of HSP nephritis (HSPN) in children remains controversial, but many clinicians administer an immunosuppressive agent with a corticosteroid. A previous study reported that leflunomide (LEF) with a corticosteroid was effective for adult patients with HSPN and nephrotic proteinuria. However, data on this treatment in pediatric patients is limited. METHODS We described our experience at a single center on the use of LEF in 5 pediatric patients who had IgA vasculitis with proteinuria that was nearly 50 mg/kg (nephrotic range) and remained high despite administration of intravenous steroid, and biopsy-proven nephritis. All patients had class II to IIIb lesions based on the International Study of Kidney Disease in Children (ISKDC). RESULTS We successfully treated all 5 children who had IgA vasculitis with nephritis using LEF with a corticosteroid. Four patients achieved a complete remission of proteinuria, and 1 patient had significantly reduced proteinuria. The children received LEF for 6 months to 12 months, and none of them had severe adverse events. CONCLUSIONS To our knowledge, this is the first case series to report successful treatment of pediatric HSPN with LEF in combination with a corticosteroid.

Abstract
BACKGROUND Knowledge on normal progress and treatment of Henoch-Schönlein purpura nephritis (HSPN) is limited. This study reviews outcome, clinical, pathological, and therapeutic factors affecting the prognosis of HSPN patients. METHODS Forty-nine children with biopsy-confirmed HSPN diagnosed between September 2008 and 2018 were included. Demographics, clinical and laboratory data, treatment, and outcome were recorded at the time of biopsy, 3, 6, 12, and 24 months and at last visit. Clinical outcome was graded according to Meadow's criteria. RESULTS The median age at time of biopsy was 10.1 years (IQR:5.7) and female/male ratio 24/25. At presentation, 40.8% of patients had nonnephrotic proteinuria, 18.4% nephrotic syndrome (NS), 4.1% nephritic syndrome (NephrS), and 36.7% NephrS+NS. There were 11 patients with an estimated glomerular filtration rate below 90 ml/min/1.73 m2. Biopsy specimens were classified according to International Study of Kidney Diseases in Children (ISKDC) and Oxford Classification MEST-C scoring systems. Forty-one patients received angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, 37 patients steroids, and 35 patients other immunosuppressive medications. At last visit, 24 patients had stage 1 chronic kidney disease (CKD), three stage 2 CKD, and two had stage 5 CKD. Neither clinical parameters nor ISKDC biopsy grade or treatment modalities effected the final outcome. The Oxford classification showed significantly increased segmental glomerulosclerosis in patients with unfavorable outcome. Favorable outcome was associated with shorter time from kidney involvement to biopsy and start of treatment. CONCLUSION A large proportion of patients continued to show signs of CKD at last follow-up while only a small proportion developed stage 5 CKD.

Abstract
Henoch-Schönlein purpura (HSP) is the most common small vessel vasculitis in children with an annual incidence of between 10 and 30 per 100,000. It is an inflammation that affects many organs primarily in the skin, gastrointestinal (GI) tract, musculoskeletal, also vital organs like kidneys and lungs which may lead to chronic kidney disease and pulmonary hemorrhage. In this review, we are showing the characteristics of Saudi patients with HSP and the relation with preceding infections, gender, and seasonal variations in addition to the common and most severe systemic involvements. We found cases that were challenging to diagnose and others with unfortunate fetal complications.

Abstract
BACKGROUND IgA vasculitis (IgAV) is the most common vasculitis of childhood. Renal involvement defines late morbidity of the disease. A better understanding of the pathophysiology of the progression to kidney disease and predictive biomarkers are required for better management of IgAV and its nephritis (IgAVN). OBJECTIVES An untargeted metabolomics approach was performed to reveal the underlying molecular mechanism of disease pathogenesis and to define potential biomarkers from plasma samples from IgAV and IgAVN patients. METHODS Forty-five active IgAV patients (H) and six healthy controls (C) were enrolled in the study. Plasma samples were collected on the same day of diagnosis and before any immunosuppressive treatment was initiated. At the time of diagnosis and sample collection, none of the patients had renal involvement. We used Quadrupole Time of Flight Mass Spectrometry (Q-TOF LC/MS) to investigate the alterations in plasma metabolomic profiles. Three separate pools were created: healthy controls (group C), active IgAV patients who did not develop renal involvement (group H), and patients who developed IgAVN at follow up (group N). Peak picking, grouping, and comparison parts were performed via XCMS (https://xcmsonline.scripps.edu/) software. RESULTS At follow-up, IgAVN developed in 6 out of 45 IgAV patients. The median time of renal involvement development is 23 days (range 5-45 days). Of these, 3 had nephritic proteinuria, one had nephrotic proteinuria, and 2 had microscopic hematuria. There were no significant differences in gender, age, clinical manifestations, and laboratory findings between the six patients who developed renal involvement and those who did not. In multivariate analysis, there was no significant association between any of the defined demographic and clinical characteristics (male sex, gastrointestinal system involvement, joint involvement, CRP, WBC, PLT) and the occurrence of renal involvement. Totally 2618 peaks were detected for group H, N, and C. Among them, 355 peaks were found to be statistically significant and reliable (p<0.05), and 155 of these peaks were found to be changed (fold change >1.5) between the groups C and H, and 66 peaks were found to be changed (fold change >1.5) between the groups H and N. The number of the peaks on the intersection of the peaks found to be different between the groups (C and H) and (H and N) was 39. Based on putative identification results, 15 putatively identified metabolites matched with 11 peaks were presented as biomarker candidates after careful evaluation with a clinical perspective. CONCLUSION We suggest that DHAP (18:0), prostaglandin D2/I2, porphobilinogen, 5-methyltetrahydrofolic acid, and N-Acetyl-4-O-acetylneuraminic acid/N-Acetyl-7-O-acetylneuraminic acid may serve as biomarkers for predicting kidney disease. Future studies with larger groups of IgAV patients are needed to validate the identified metabolic profile.

Abstract
Background: Henoch-Schönlein purpura (HSP) is one of the most common systemic types of vasculitis in children. Although it is a self-limited disease, life-threatening complications such as nephritis may occur. Early diagnosis and follow up might improve the long term outcome in renal involvement. There are few studies that have evaluated HSP in Iran. Objectives: The purpose of this study was to investigate demographic, laboratory data and clinical presentations of admitted HSP patients in a tertiary referral center, over a twelve-year period. Methods: This retrospective descriptive study evaluated 195 patients, diagnosed with HSP, who were admitted to Namazi Hospital in southwest of Iran (2006 - 2018). Demographic, clinical and laboratory findings, as well as treatment outcome of HSP patients were collected. Results: There were 118 males and 77 females with the mean age of 6.7 ± 3.21 years. About 70 (36%) patients showed common cold symptoms two weeks before HSP presentations. Admission course was 1 - 17 days (mean 4.55 ± 2.83) and autumn was recorded with the highest number of admitted patients (44.1%). In the course of hospitalization, 100% of the patients presented with palpable purpura, 61.02% with joint pain and 19.49% with abdominal pain. Moreover, 17.95% of the patients were noted with renal involvement. Laboratory data shows that more than half of patients (54%) had leukocytosis, only 9% of patients had positive CRP but all the patients had high erythrocyte sedimentation rate (ESR). Total of 43.1% of the patients received corticosteroids. Conclusions: The observed number of male patients with HSP was higher than females and the highest frequency of the HSP cases was observed in autumn. Joint pain and abdominal pain were the predominant clinical presentations, following skin purpura. The presented data can help with further HSP diagnosis and treatment plan.

Abstract
The outcomes of rheumatic diseases (RDs) have improved over the past decades. However, a significant proportion of the patients still suffer from end-stage renal disease (ESRD) and have to bear the burden of hemodialysis. It is crucial to prevent patients with RDs from developing ESRD from viewpoints of medicine and medical economics. For those who already have ESRD, it is important to improve vial prognosis and quality of life through appropriate management of disease activity and comorbidities related to ESRD. Thus, rheumatologists and nephrologists need to recognize risk factors associated with progression to ESRD along with their appropriate management. Although the activity of most RDs tends to decrease after initiation of hemodialysis, disease activity may still increase, and recognizing how to appropriately use immunosuppressive agents even after the development of ESRD is crucial. The treatment of RDs needs extra attention as hydroxychloroquine requires more frequent monitoring for adverse drug reactions; therapeutic drug monitoring is necessary for mycophenolate mofetil, cyclosporine A, and tacrolimus; cyclophosphamide and azathioprine need dose adjustments; methotrexate and bucillamine are contraindicated in patients with ESRD; leflunomide and sulfasalazine do not require significant dose reduction and iguratimod should be carefully administered. The pharmacokinetics of biological agents such as rituximab or belimumab are not affected by ESRD, and dose adjustments are not necessary. Collaboration between rheumatologists and nephrologists is needed more than ever and is expected to produce a complementary effect and achieve better outcomes in clinical settings, although this cooperation has not always been conducted appropriately.

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
Abstract
Objectives
IgA vasculitis (IgAV, formerly known as Henoch–Schönlein purpura) is the most common cause of systemic vasculitis in childhood. To date, there are no internationally agreed, evidence-based guidelines concerning the appropriate diagnosis and treatment of IgAV in children. Accordingly, treatment regimens differ widely. The European initiative SHARE (Single Hub and Access point for paediatric Rheumatology in Europe) aims to optimize care for children with rheumatic diseases. The aim therefore was to provide internationally agreed consensus recommendations for diagnosis and treatment for children with IgAV.
Methods
Recommendations were developed by a consensus process in accordance with the EULAR standard operating procedures. An extensive systematic literature review was performed, and evidence-based recommendations were extrapolated from the included papers. These were evaluated by a panel of 16 international experts via online surveys and subsequent consensus meeting, using nominal group technique. Recommendations were accepted when ⩾80% of experts agreed.
Results
In total, 7 recommendations for diagnosis and 19 for treatment of paediatric IgAV were accepted. Diagnostic recommendations included: appropriate use of skin and renal biopsy, renal work-up and imaging. Treatment recommendations included: the importance of appropriate analgesia and angiotensin-converting enzyme inhibitor use and non-renal indications for CS use, as well as a structured approach to treating IgAV nephritis, including appropriate use of CS and second-line agents in mild, moderate and severe disease along with use of angiotensin-converting enzyme inhibitors and maintenance therapy.
Conclusion
The SHARE initiative provides international, evidence-based recommendations for the diagnosis and treatment of IgAV that will facilitate improvement and uniformity of care.

[PMID: 30819179 PMCID: PMC6393980 DOI: 10.1186/s12969-019-0311-z] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2018] [Accepted: 02/21/2019] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Nephritis is the most important chronic complication of IgA Vasculitis (IgAV)/Henoch-Schönlein purpura (IGAV/HSP) and thus the main prognostic factor of this most common childhood vasculitis. Since the prognosis and treatment selection depends on the mode of interpretation of biopsy material, in this manuscript we have presented several issues related to the uneven application of different histological classifications in IgAV/Henoch-Schönlein purpura nephritis (HSPN). The nephritis of IgAV/IGAV/HSP will be abbreviated as HSPN for this paper. MAIN BODY In clinical practice we use different histological classifications for HSPN. It is not known which of these classifications best correlates with severity of renal disease and renal outcome in IgAV/IGAV/HSP. One of the major problem with existing histological classifications is that there is no consensus on the implementation of biopsy in the treatment of HSPN. There is a histologic classification system conventionally used in HSPN, of the International Study of Kidney Disease in Children (ISKDC). On the other hand there is the new classification system suggested for IgA nephropathy, the Oxford classification. The latter has been validated only in IgA nephropathy. There are also two further histologic classifications of Haas and Koskela that have been developed. Current treatment strategies in HSPN are not standardised nor predominantly based on histological classification. CONCLUSION One of the possible solutions to problems related to the application of different histological classification in HSPN is the implementation of multicenter multinational prospective studies with joint collaboration between pediatric rheumatologists, nephrologists and nephropathologists to correlate the clinical features and outcome with the classification systems as well among the classifications. This classification should be the basis for the construction of guidelines for the treatment of patients with HSPN.

Abstract
Primary vasculitides that affect children are a challenging and complex group of disorders that may involve any system of the body and lead to significant morbidity and mortality. In recent years, there have been significant advances in the field of childhood vasculitides, including the development of classification criteria and outcome assessment. Although some forms of vasculitis occur in both children and adults, considerable differences exist between childhood and adult vasculitides; we review childhood vasculitides, thus highlighting their differences with the adult forms of the disease. We will also discuss monogenic forms of vasculitis, such as deficiency of adenosine deaminase type 2 (DADA2) and haploinsufficiency of A20 (HA20).

Abstract
BACKGROUND Henoch-Schönlein purpura (HSP) is a common form of vasculitis in children. It typically involves small vessels of the skin, the gastrointestinal (GI) tract, joints, and kidneys. GI involvement is the most severe short-term complication and GI bleeding is a major complication of HSP, but there is no established predictive marker of GI bleeding. Blood neutrophil-to-lymphocyte ratio (NLR) has been proposed as a potentially useful marker of clinical outcome in diseases with an inflammatory component. The aim of this study was to clarify the association of NLR with HSP and investigate the usefulness of NLR as a marker to predict GI bleeding in children with HSP. METHODS All patients with newly diagnosed HSP were reviewed retrospectively. White blood cell count, hemoglobin, platelet counts, mean platelet volume, neutrophil and lymphocyte count were evaluated. NLR and platelet-to-lymphocyte ratio (PLR) were calculated using complete blood count data. RESULTS This study involved 141 HSP patients. GI involvement was found in 65 patients (46.1%), and, of these, 15 (10.6%) had GI bleeding. At the time of diagnosis, NLR was significantly higher (P = 0.001) and PLR significantly lower (P = 0.032) in patients with GI bleeding than in those without GI bleeding. On logistic regression analysis, NLR was the only independent predictor of GI bleeding (P = 0.004). The optimal cut-off of NLR for predicting GI bleeding was 2.86 (sensitivity, 73%; specificity, 68%). CONCLUSIONS NLR, a simple and easily obtainable parameter, is a potential predictive marker of GI bleeding in children with HSP.

Abstract
To identify the risk factors for developing renal involvement and severe kidney disease in Chinese childhood Henoch-Schönlein purpura (HSP) patients.This was a retrospective study of 2731 children with HSP diagnosed between 2012 and 2015. We analyzed their demographic data, clinical manifestations, and laboratory tests retrospectively. Multivariate logistic regression analysis was used to assess the risk factors.Renal involvement occurred in 844 HSP patients (35.60%), and severe kidney disease occurred in 104 HSP patients (4.39%). Age over 6 years old at onset, colder season, more than 8 days interval between symptom onset and diagnosis, residence in rural, recurrence, angioedema, and the central nervous system (CNS) involvement were the significant risk factors for renal involvement. At the same time, age over 6 years at onset, more than 8 days interval between symptom onset and diagnosis, recurrence, angioedema, and CNS involvement were highly associated with severe kidney disease. Angioedema, longer interval between symptom onset and diagnosis, older age at HSP onset, and recurrence are prognostic indicators for renal involvement and severe kidney disease in children with HSP. The onset in colder season and rural residence associated with an increased risk for renal involvement, and the CNS involvement had an increased risk for severe kidney disease.HSP tends not to be self-limiting, and could progress into renal involvement or severe kidney disease for some of the HSP patients. Pediatricians should pay more attention to the children diagnosed with HSP, who also have these risk factors, for potential to develop renal involvement, and severe kidney disease, especially.

Abstract
Introduction Vasculitides are a heterogeneous group of diseases characterized by inflammation of the blood vessel walls. Etiological factors include infections, drugs, connective tissue diseases, and malignancies. Aim To examine the demographic characteristics, etiological factors, and treatment options in 75 patients with leukocytoclastic vasculitis. Material and methods The study included 75 patients diagnosed with leukocytoclastic vasculitis at our clinic. The patients’ medical records were reviewed to determine their age, sex, presence of systemic symptoms, possible etiological factors, laboratory results, types of cutaneous lesions, locations of the lesions, treatment options, and disease course. Results There were 43 women and 32 men. Cutaneous lesions affected only the lower limbs in 60 of the 75 patients (80%) and usually presented as palpable purpura (64%, n = 48). Arthralgia (26.7%, n = 20) was the most frequent extracutaneous symptom. Of the patients with secondary vasculitis, the most common causes were infections and drugs. The mean age of the patients with Henoch-Schönlein purpura was 26.8 years. There was no significant association between age and renal, gastrointestinal, or joint involvement. Conclusions The most common form of vasculitis in our study was cutaneous leukocytoclastic vasculitis. In most of the patients it appeared to be idiopathic. Among drugs, antibiotics were the most common etiological factor. In 4 patients, the cutaneous leukocytoclastic vasculitis behaved like the paraneoplastic syndrome.

Abstract
BACKGROUND Some allergic inflammation-associated mediators have been reported in acute stage of Henoch-Schönlein purpura (HSP). However, the association of children with allergic diseases and their subsequent risks of HSP and HSP nephritis remain unknown. METHODS In this study, we included 2,240 children with HSP diagnosed between 2000 and 2008 as well as 8,960 non-HSP controls matched for age, sex, and level of urbanization. The odds ratios (ORs) of HSP were calculated with respect to associations with pre-existing allergic diseases. RESULTS Children with allergic diseases had an increased subsequent risk of HSP; the lowest adjusted OR (aOR) was 1.33 for allergic conjunctivitis (95% confidence interval (CI): 1.17-1.52) and the highest was 1.68 for asthma (95% CI: 1.48-1.91). The aOR increased to 2.03 (95% CI: 1.80-2.31) in children with at least two allergic diseases. Children who visited medical institutes more often per year for associated allergic diseases had an increased risk of HSP. Of the 2,240 children with HSP, 249 (11%) had HSP nephritis and 45.8% of those with nephritis had history of any allergic disease. CONCLUSION Atopic children had an increased subsequent risk of HSP but not an increased risk of HSP nephritis.

Abstract
Elevation of Th2 cytokine-driven inflammatory mediators has been reported in acute stage of Henoch-Schönlein purpura (HSP). However, the temporal interaction between Th2-mediated allergic diseases and HSP with renal involvement remains unknown. Herein, we conducted a population-based cohort analysis to investigate the risk of HSP and renal involvement in children with atopic dermatitis (AD) as 1 of the first steps in the atopic march.From 2000 to 2007, 95,208 children with newly diagnosed AD and 190,416 randomly selected non-AD controls were included in the study. By the end of 2008, incidences of HSP in both cohorts and the AD cohort to non-AD cohort hazard ratios (HRs) and confidence intervals (CIs) were measured. Comparison of renal involvement in HSP between children with and without AD was analyzed.The incidence of HSP during the study period was 1.75-fold greater (95% CI: 1.27-2.42) in the AD cohort than in the non-AD cohort (14.2 vs 8.11 per 100,000 person-years). The AD to non-AD HR of HSP was greater for girls (1.92, 95% CI: 1.18-3.13), children older than 6 years (2.54, 95% CI: 1.15-5.59), and those living in less urbanized area (2.74, 95% CI: 1.10-6.82). Concurrent allergic rhinitis or asthma did not increase the HR of HSP further. The HR for HSP in AD children increased from 0.67 (95% CI: 0.41-1.11) for those with ≤2 AD-related visits to 9.77 (95% CI: 6.44-14.8) for those with >4 visits (P < 0.0001, by the trend test). The risk of developing HSP in the AD cohort was highest within first year after AD diagnosis (HR: 3.99; 95% CI: 1.61-9.89). AD cohort with HSP had higher occurrence rate of renal involvement, particular hematuria, than non-AD cohort with HSP.AD children had a greater risk of developing HSP and HSP with renal involvement. Further research is needed to clarify the role of allergy in the pathogenesis of HSP and renal involvement.

Abstract
UNLABELLED The main aim of this study was to evaluate the relationship between obesity and renal involvement in children with Henoch-Schönlein purpura (HSP). A retrospective study of 141 pediatric patients with HSP was conducted in our hospital. The clinical data of all patients were collected from the electronic medical record management system from January 2010 to June 2014. The possible risk factors of renal involvement, especially obesity, were analyzed using univariate and multivariate analyses. Renal involvement occurred in 45/141 of the patients. A univariate analysis showed that an age more than 7 years at onset, persistent purpura, obesity, time from symptoms onset to diagnosis more than 14 days, and decreased C3 all increased the risk of renal involvement in HSP. The forward stepwise logistic regression analysis indicated obesity (odds ratio (OR) 4.43, 95 % confidence interval (CI) 1.896 to 10.358), age more than 7 years at onset (OR 2.81, 95 % CI 1.142 to 6.907), and persistent purpura (OR 2.57, 95 % CI 1.119 to 5.909) were independent risk factors for renal involvement. CONCLUSIONS Our results show that obesity can increase the hazard of renal involvement in children with HSP and reconfirm that older age at onset and persistent purpura are the independent risk factors for renal involvement. WHAT IS KNOWN • There have been some reports that obesity was associated with the development of renal injury. • It is not clear whether obesity can increase the risk of renal involvement in children with HSP. What is New: • The main finding of this study is that obesity can increase the hazard of renal involvement in children with HSP.

Could serum pentraxin 3 levels and IgM deposition in skin biopsies predict subsequent renal involvement in children with Henoch-Schönlein purpura? Pediatr Nephrol 2015; 30:969-74. [PMID: 25543194 DOI: 10.1007/s00467-014-3026-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2014] [Revised: 11/26/2014] [Accepted: 12/01/2014] [Indexed: 11/30/2022]
Abstract
BACKGROUND The aim of this study was to evaluate the potential of serum pentraxin 3 (PTX3) values as an early predictor of subsequent renal involvement in patients with Henoch-Schönlein purpura (HSP) with no abnormalities on urinary examination and in renal function tests at disease onset. METHODS This was a prospective cohort study which included 60 pediatric patients with HSP (age range 3-15 years) who were diagnosed between February 2011 and October 2012 and 60 age- and sex-matched healthy controls. The patients were followed up for at least 18 months. Clinical findings were recorded for all patients at first examination, and blood samples for routine laboratory parameters and PTX3 value as well as skin biopsy specimens were obtained from each subject. RESULTS Of the 60 patients with HSP, 29 (48.3 %) developed subsequent renal involvement, of whom four underwent kidney biopsy. The mean serum PTX3 level of patients with subsequent renal involvement was significantly higher than those of patients without renal involvement and of the controls (2.20 ± 1.30 vs. 1.36 ± 0.85 and 1.03 ± 0.7 ng/ml, respectively; p = 0.004). Immunofluorescence evaluation of skin biopsy revealed that in addition to immunoglobulin A (IgA) deposition, the IgM deposition was significantly associated with subsequent renal involvement (p = 0.008). CONCLUSIONS A high PTX3 level and IgM staining in skin biopsies from HSP patients may be harbingers of subsequent renal involvement.

Abstract
Introduction Henoch–Schönlein purpura is an immunoglobulin A-mediated, small vascular inflammatory disease that can be associated with palpable purpura, arthralgia, abdominal pain, or nephritis. The presence of purpura facilitates the diagnosis of Henoch–Schönlein purpura at the onset of associated symptoms, whereas the absence of purpura makes the diagnosis challenging. It is important to diagnose Henoch–Schönlein purpura with delayed-onset skin purpura to avoid unnecessary surgery for acute abdomen. Most cases of Henoch–Schönlein purpura with severe abdominal pain are treated with low-dose steroids and intravenous immunoglobulin. Case presentation A 15-year-old Korean girl complained of severe abdominal pain and delayed-onset purpura on admission. Henoch–Schönlein purpura was diagnosed based on endoscopic findings of hemorrhagic duodenitis and duodenal vasculitis and abdominal computed tomography findings of edematous bowels. Two common initial treatments, a low-dose steroid and intravenous immunoglobulin, were administered, but there was no improvement for 1 month. Subsequently, we used high-dose intravenous methylprednisolone pulse therapy (30mg/kg/day, with a maximum of 1g/day), which dramatically alleviated her abdominal symptoms. Conclusions High-dose intravenous methylprednisolone pulse therapy can be used as the ultimate treatment for delayed-onset Henoch–Schönlein purpura with severe abdominal pain when symptoms do not improve after low-dose steroid and intravenous immunoglobulin treatments.

Abstract
A 29-year-old woman was diagnosed with Henoch-Schönlein purpura nephritis (HSPN) based on the presence of purpura and histopathological findings showing crescent formation, mesangial proliferation and IgA deposition in the glomerular mesangium. She was treated with high-dose steroids; however, the nephritic syndrome persisted. Therefore, we diagnosed her with steroid-resistant HSPN and decided to add treatment with cyclosphamide pulse therapy. After one year of treatment, the histopathological findings, including crescent formation and IgA deposition, improved, as confirmed on a renal biopsy, and the patient fulfilled the criteria for complete remission. Cyclophosphamide pulse therapy may be considered an effective treatment for intractable HSPN.

Abstract
Henoch-Schönlein purpura (HSP) is the most common vasculitis in children, in whom prognosis is mostly dependent upon the severity of renal involvement. Nephritis is observed in about 30% of children with HSP. Renal damage eventually leads to chronic kidney disease in up to 20% of children with HSP nephritis in tertiary care centres, but in less than 5% of unselected patients with HSP, by 20 years after diagnosis. HSP nephritis and IgA nephropathy are related diseases resulting from glomerular deposition of aberrantly glycosylated IgA1. Although both nephritides present with similar histological findings and IgA abnormalities, they display pathophysiological differences with important therapeutic implications. HSP nephritis is mainly characterized by acute episodes of glomerular inflammation with endocapillary and mesangial proliferation, fibrin deposits and epithelial crescents that can heal spontaneously or lead to chronic lesions. By contrast, IgA nephropathy normally presents with slowly progressive mesangial lesions resulting from continuous low-grade deposition of macromolecular IgA1. This Review highlights the variable evolution of similar clinical and histological presentations among paediatric patients with HSP nephritis, which constitutes a challenge for their management, and discusses the treatment of these patients in light of current guidelines based on clinical evidence from adults with IgA nephropathy.

Abstract
BACKGROUND The management of Henoch-Schönlein purpura nephritis (HSPN) in childhood is controversial. Adjuvant therapies such as immunoglobulin, anticoagulants, and vitamins have been used with conventional treatments despite a lack of evidence of their efficacy. OBJECTIVE The aim of this study was to review the scientific literature regarding adjuvant treatments administered with conventional drugs in the treatment of childhood HSPN. METHODS Published articles were identified from the MEDLINE and EMBASE databases (1988-December 2008; key words: Henoch-Schönlein nephritis and Henoch-Schönlein purpura). The search was limited to published English-language studies on therapeutic options for HSPN in children. RESULTS A total of 12 studies were identified and included in this review; most (n = 8) were case series or retrospective studies. Studies of conventional therapy combined with adjuvant treatment should be interpreted with caution. In particular, factor XIII administration was reported to improve kidney symptoms in 1 study. Based on the results from 9 studies, no convincing evidence on intravenous immunoglobu-lin, urokinase, or anticoagulants was identified. No substantial information was available on the benefit of antiplatelet agents or heparin in treating HSPN. Integrating treatment with vitamin E was not recommended based on the results from 1 randomized controlled trial. Fish oil was reported to be effective in 1 case series. CONCLUSIONS Studies concerning the treatment of HSPN in children with adjuvant therapies were retrospective and recommendations were drawn from level IV evidence. One randomized controlled trial on the use of tocopherol as adjuvant treatment was identified; however, no clinical utility was reported. At present, there is no strong evidence supporting benefits with the use of adjuvant treatments.

Abstract
OBJECTIVES To analyse the clinical features of Henoch-Schönlein purpura (HSP) with or without nephritis in Chinese children and to determine the risk factors for renal involvement. METHODS Patient characteristics, clinical parameters and laboratory data were retrospectively analysed in patients with HSP with or without nephritis. Logistic regression analysis was used to identify the risk factors for renal involvement. RESULTS A total of 535 patients with HSP were included in the study. HSP nephritis occurred in 267 patients (49.9%), ranging from isolated haematuria in 5.2%, mild proteinuria in 77.5%, moderate proteinuria in 6.4% and severe proteinuria in 10.9% of cases. In 90% of the cases, nephritis developed within 1 week of HSP onset; 98.5% of the cases with nephritis developed the condition within 1 month. Risk factors for the development of nephritis were age ≥6 years, purpura on sites other than the lower limbs and the presence of occult blood in the stool. CONCLUSION These results suggest that patients aged ≥6 years, or who have purpura on the upper limbs or face, or who have occult blood in the stool should be particularly monitored for signs of nephritis.

Abstract
Objective To evaluate the parameters associated with significant gastrointestinal (GI) involvement in Henoch-Schönlein Purpura (HSP), and construct a scoring system for the identification of patients at high risk of gross blood in stools. Study design Data for HSP patients hospitalized at each of seven institutes were retrospectively analyzed. Patients were divided into four groups according to the consequent severity of GI involvement. Identification of laboratory parameters at the time of admission were then used to differentiate the groups, and a scoring system to predict gross intestinal bleeding was constructed. Prognostic efficiency, correlation with the subsequent duration of abdominal pain, and association with manifestations excluding abdominal pain were also analyzed. Results An analysis of variance (ANOVA) test showed significant intergroup differences in white blood cell (WBC) count, neutrophil count, serum albumin, potassium, plasma D-dimer and coagulation factor XIII activity. A scoring system consisting of these parameters showed a good prognostic value for gross intestinal bleeding in a receiver operating characteristic (ROC) analysis, and a cut-off value of 4 points showed a sensitivity of 90.0% and specificity of 80.6%. The score was also correlated with the duration of abdominal pain after admission. A significantly higher score (s) was observed in patients presenting with nephritis, although the predictive value was poor. Conclusion A scoring system consisting of generally available parameters was of use in predicting severe GI involvement in HSP patients. Although further study is needed, initial therapy in accordance with disease activity may be taken into consideration using this scoring system.

Abstract
The current study aimed to define evidence-based admission criteria of pediatric Henoch-Schonlein purpura (HSP). In addition, we aimed to better characterize epidemiological and clinical features of pediatric HSP in Israel. We performed a retrospective cohort study of all children with HSP admitted during a 15 years period to a single pediatric department. We strictly collected the clinical data of all HSP cases. Each case was categorized as either "necessary admission" or "unnecessary admission." We compared the two groups, using initially Chi square (χ(2)) and student "t" tests, and thereafter, we employed logistic stepwise regression analysis. One hundred and sixty-three children with HSP were included. A set of six clinical criteria of which the presence of minimum one predicts the need for hospitalization were identified including: orchitis, moderate or severe abdominal pain, arthritis involving more than two joints, proteinuria, clear evidence of gastrointestinal bleeding, and inability to ambulate. In conclusion, we suggest a predictive model for the admission of pediatric patients with acute HSP. The implementation of this model can significantly reduce unnecessary admissions.

Abstract
Myeloid-related protein (MRP) 8/14 complex is a marker of monocyte and neutrophil activation. We evaluated whether serum MRP8/14 complex is associated with clinical manifestations and pathological findings of Henoch-Schönlein purpura nephritis (HSPN). Patients were divided into two groups based on serum MRP8/14 complex levels at renal biopsy. Group 1 consisted of 18 HSPN patients with less than median (670 ng/ml) MRP8/14 complex levels, and Group 2 of 12 HSPN patients with greater than median levels. Clinical manifestations, laboratory findings and serum E-selectin levels, as a marker of vascular endothelial cell dysfunction, as well as histological and immunohistochemical findings were investigated for both groups. We also measured MRP8/14 complex levels in disease control and healthy control children. Urinary protein excretions, serum MRP8/14 complex levels, and serum E-selectin levels were all higher in Group 2 than in Group 1 patients. Serum MRP8/14 complex levels were higher in HSPN patients than in controls. Serum MRP8/14 complex levels were strongly associated with serum E-selectin levels. Pathological findings revealed that the proportions of patients with ISKDC grades III, IV and V in Group 2 were higher than in Group 1. Our findings suggest that serum MRP8/14 complex levels might be associated with the severity of renal injury and endothelial cell dysfunction in HSPN patients.

Abstract
Henoch-Schönlein purpura is the most common form of vasculitis in childhood and adolescence. It is manifested as palpable purpuras in the region of position-dependent extremities with otherwise good clinical general condition. The expression on the skin can, however, be variable so that sometimes other differential diagnoses must be included. In typical cases an extensive diagnostic procedure is unnecessary but the short-term complications of abdominal symptoms as well as the long-term complications of nephritis should be pursued. If musculoskeletal symptoms occur paracetamol or non-steroidal anti-inflammatory drugs are effective as are steroids for reducing the duration of abdominal pain. The effectiveness of steroid prophylaxis of renal damage is still controversial.

Abstract
Knowledge about how to treat severe Henoch-Schönlein nephritis (HSN) is scarce. The aim of our study is to compare cyclosporine A (CyA) and methylprednisolone pulses (MP) in the treatment of severe HSN. Out of 24 pediatric HSN patients with nephrotic-range proteinuria or crescentic HSN in kidney biopsy, seven were randomized to receive CyA for 12 months at an initial dose of 5 mg/kg and eight to receive 3 MP pulses of 30 mg/kg followed by prednisone for 4 months. The other nine patients received identical treatment without randomization. Kidney biopsies were performed at inclusion and after 2 years. The primary outcomes were the duration of proteinuria and hematuria, estimated glomerular filtration rate, and renal biopsy histology. All the 11 CyA-treated patients achieved resolution of nephrotic-range proteinuria within 3 months, while the MP-group response was slower, and in 6/13 was not achieved with the initial treatment. Additional immunosuppressive treatment was needed in none of the CyA-treated patients but in six patients treated with MP (difference in proportion 46%, p = 0.008). The 2-year control biopsies were similarly improved in both groups. After mean 6.1 years (2.2-10.4 years), 16 patients (eight CyA, eight MP) had no renal symptoms and six (three CyA, three MP) had persistent nephropathy but normal renal function. One MP-treated patient had reduced renal function and another had developed ESRD and received a renal transplant. CyA gave a 100% resolution of nephrotic-range proteinuria and a 100% renal survival rate without additional therapy after a mean follow-up of 6 years. Treatment of HSN with CyA is efficacious, safe and not inferior to MP.

Abstract
INTRODUCTION Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood. It is characterized by symptoms including nonthrombocytopenic purpura, abdominal pain, haematuria/proteinuria, and arthralgia/arthritis. The pleiomorphism of clinical signs in HSP could be confused with other conditions or other vasculitis forms. OBJECTIVE Evaluation of HSP clinical presentation, the onset and severity of renal manifestation in affected children and their outcome. METHODS A retrospective study of 49 patients diagnosed with HSP was conducted from September 1999 to September 2009. Children with severe renal manifestations (nephrotic range proteinuria, with or without nephrotic or nephritic syndrome) have undergone kidney biopsy. RESULTS Twenty-five patients developed renal manifestations after onset of the disease. In our study child's older age was a risk factor for association with HSP nephritis. Six of the patients required kidney biopsy. They were successfully treated with various immunosuppressive protocols, as well as three of nine patients with nephrotic range proteinuria. Two patients developed most severe form of HSP nephritis, nephrotic-nephritic syndrome with histology grade IIIb/IVb. During the study period (average followup 6 years), all patients had a normal global renal function with mild proteinuria in only two cases. The prognosis of renal involvement was better than reports from other patient series. CONCLUSION Long-term morbidity of HSP is predominantly attributed to renal involvement. During the study period, no patient had renal insufficiency or end stage renal disease after various combinations of immunosuppressive treatment. It is recommended that patients with HSP nephritis are followed for longer periods of time with a regular measurement of renal function and proteinuria.

Abstract
Nephritis develops in 18-81% of Henoch-Schönlein purpura patients, and the long-term outcomes of this nephritis show great variation. A nephrotic state at disease onset has been proposed as a predictor of poor renal outcomes. We studied 42 children with Henoch-Schönlein purpura nephritis (HSPN) who presented with a nephrotic state during the early phase of the disease. The median age of the patients at the time of diagnosis was 7.4 years. The median follow-up period was 6.2 years. Twenty-five children (60%) made a complete recovery; nine (21%) progressed to end-stage renal disease. Multivariate logistic regression analyses revealed that the nephrotic state lasting for more than 3 months had a significant effect on renal outcomes (odds ratio 11.6; 95% confidential interval, 1.16-348.4; p = 0.03), whereas initial renal insufficiency, renal pathological findings, age at onset, and types of treatment did not. These findings indicate that clinical presentation, particularly duration of the nephrotic state, is related to long-term outcomes in HSPN patients with nephrosis. Our results also indicate that the therapeutic options for HSPN patients with a nephrotic state should be based on the clinical presentation rather than on the initial pathological findings alone.

Abstract
To evaluate the therapeutic role of cyclosporin A (CyA) for the treatment of Henoch-Schönlein nephritis (HSN), 29 patients (18 boys, 11 girls) with nephrotic-range proteinuria were analyzed retrospectively. Mean age was 8.6 years (range 2.0-15.5 years) at diagnosis of Henoch-Schönlein purpura (HSP). All patients had developed the nephrotic-range proteinuria at a mean interval of 4.4 months (range 0-50.7 months) after the diagnosis of HSP. Mean duration of CyA treatment was 12.3 months (range 2.6-55.0 months). Mean follow-up times were 3.7 years (range 1.2-12.9 years) from the beginning of the CyA treatment. Steroids were tapered off and stopped gradually after initiation of CyA. All patients responded to the CyA treatment within a mean of 1.8 months (range 1 week to 3.5 months). Twenty-three patients achieved stable remission with mean follow-up duration of 3.2 years and 6 patients seemed to become CyA-dependent, since they developed proteinuria when the treatment was stopped. Renal function was preserved in all patients but one who developed end-stage renal disease after poor compliance with CyA. We concluded that CyA treatment for HSN showing nephrotic-range proteinuria is very effective and a safe method, although some patients become CyA-dependent.

Abstract
Background. Henoch-Schönlein purpura (HSP) is the most common childhood vasculitis with an incidence of approximately 10 per 100 000 children. There is some evidence to support steroid therapy in the treatment of severe abdominal pain, severe nephritis, and central nervous system involvement. However, the routine use of corticosteroids is controversial. Frequent relapses, lack of response to steroid, steroid dependency, and steroid side effects may occur in some patients. Mycophenolate mofetil (MMF) gains increasing popularity in the treatment of autoimmune disorders, but hitherto, the available evidence to support the use of MMF in HSP is limited to some case study reports. Case Presentation. We report six children with HSP who failed to respond to systemic steroid therapy, whereas MMF successfully treated the manifestations of the disease. Conclusion. The manifestations of HSP disappeared mainly during the first week of treatment with MMF and all the patients were in a complete remission at the end and after discontinuation of the therapy. In our experience, MMF appeared to be safe and effective for the maintenance of remission in the HSP patients.

Abstract
The aim of this study was to evaluate the effectiveness of intravenous corticosteroid therapy when Henoch-Schönlein purpura (HSP) patients are unable to tolerate oral medications due to abdominal pain. We retrospectively analyzed 111 children with a diagnosis of HSP (mean age 6.9 ± 2.3 years, male:female = 54:57) from the years 2000 to 2007. They were divided into two groups: 49 patients received only oral prednisolone (PL group) and 62 patients received oral prednisolone after intravenous dexamethasone (Dexa + PL group). Palpable purpura was seen in all 111 patients (100%), abdominal pain in 55 (50%), and arthralgia in 65 (59%). Dexa + PL group had significantly longer duration of fasting than PL group (0.7 ± 1.2 vs. 0.02 ± 0.1 days, P < 0.01) due to more severe and frequent abdominal pain (68 vs. 27%, P < 0.01). Intravenous dexamethasone resulted in the rapid resolution of abdominal pain or arthralgia in all patients without major complications. However, the development of nephritis (21% in PL group versus 32% in Dexa + PL group, P = 0.098), the number of relapse (4 vs. 11%, P = 0.167), and persistent nephritis at last follow-up (12 vs. 16%, P = 0.563) were not different between the two groups despite more severe symptoms in Dexa + PL group. Intravenous dexamethasone followed by oral prednisolone may be a useful and effective therapeutic strategy in HSP children who cannot tolerate oral medications due to severe abdominal pain.

Abstract
The childhood vasculitides are a group of diseases affecting small to large blood vessels. The two most common conditions are Henoch-Schönlein purpura (HSP) and Kawasaki disease (KD). HSP is diagnosed on the basis of typical clinical findings and is mostly a self-limiting disease. KD is the most common vasculitis in infants and the development of coronary artery aneurysms is the major complication. Early treatment with intravenous immunoglobulin and aspirin (acetylsalicylic acid) is required to minimize this risk. All other vasculitides are very rare in children and include anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis, polyarteritis nodosa and Takayasu disease. The etiology of all these vasculitic diseases is generally unknown and, therefore, no specific treatment is available. The more rare vasculitides are generally much more severe, often needing treatment with high doses of corticosteroids and immunosuppressant agents such as cyclophosphamide, azathioprine, and mycophenolate mofetil.

Abstract
AIM To identify risk factors for a child with Henoch-Schönlein purpura (HSP) either to develop nephritis (HSPN) or to contract progressive course and to obtain the currently available evidence on the efficacy of treatment options in both preventing and treating the established renal disease. METHOD Review of the literature published over the last two decades. RESULTS Persistent or recurrent purpura, severe abdominal symptoms and an older age proved as the most significant risk factors for later HSPN. The risks of long-term renal impairment are the highest in children having at presentation nephritic/nephrotic syndrome and/or more than 50% of glomeruli occupied by large crescents or sclerosing lesions. Randomized controlled trials (RCT) do not support short course prednisone at presentation of HSP in preventing persistent renal disease. Many uncontrolled studies using various treatment regimens have reported outcomes considered better than expected. However, the data from RCTs are sparse and no treatment options for the established renal disease can be currently recommended based on RCTs. CONCLUSION Severity and/or duration of extrarenal HSP symptoms and an older age are the most significant risk factors for developing HSPN, whereas clinical and histological severity at HSPN onset are in general predictive of a long-term renal impairment. The existing evidence does not support of short course prednisone in preventing persistent renal disease. A well-designed RCTs are needed in children with moderately severe or rapidly progressive (crescentic) HSPN.

Abstract
Considerable concern has been expressed on the importance of identifying an improved therapeutic protocol for use in the treatment of childhood Henoch-Schönlein purpura nephritis, primarily due to the unpredictable success shown to date in improving long-term renal outcome. This review focuses on published reports describing the outcomes of therapeutic approaches currently being used in the treatment of pediatric Henoch-Schönlein purpura nephritis, with the aim of providing information that will facilitate a treatment-based approach in children presenting with varying degrees of kidney disease. The conclusions of the authors of this review are that currently prescribed treatments of children affected by Henoch-Schönlein purpura nephritis are not adequately guided by evidence obtained in properly designed, randomized, placebo-controlled trials with outcome markers related to the progression to end stage renal disease (level I evidence). Moreover, firm evidence supporting the best practice to be applied with the aim of delaying the progression of kidney disease is still lacking.

Abstract
BACKGROUND Henoch-Schönlein purpura (HSP) primarily affects children, but age at onset is thought to be important in determining disease severity and outcome. This study compared the clinical and laboratory data from children and adults with HSP. METHODS This retrospective 5-year study enrolled 65 children and 22 adult HSP patients attending a medical center. RESULTS Gross hematuria and lower-extremity edema were significantly more frequent in adults (p < 0.05). All the children developed renal involvement within 2 weeks, while 67% of the adult patients developed hematuria by the fifth week of disease onset. Elevated white blood cell count and increased erythrocyte sedimentation rate were significantly more common in children (p < 0.05). Adults had a higher frequency of renal involvement (p < 0.05), though this was also present in 14 children (21.54%), 12 with isolated hematuria and proteinuria and two with nephrotic syndrome. All the children maintained normal renal function. Twelve adults had renal involvement (52.6%), six with progression to renal insufficiency. Patients with abdominal pain at disease onset had a significantly higher probability of developing nephrotic syndrome (p < 0.05). Logistic regression revealed that age >20 years, male, bloody stools, clinical course with relapse of purpuric rash, and persistent rash for >1 month were poor prognostic indicators for HSP nephritis (p < 0.05). CONCLUSIONS HSP nephritis in adults had a higher risk of progression to renal insufficiency. More aggressive treatment and extended follow-up with repeated urinalysis for at least 6 weeks were often necessary, especially in older patients.
