Reicy R, Jari M. Comparison of Different Treatment Regimens for Long-term Improvement of Renal Function in Patients with Henoch-Schönlein Purpura: A Systematic Review. Curr Rheumatol Rev 2024; 20:57-64. [PMID: 37698064 DOI: 10.2174/1573397119666230825163008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 06/27/2023] [Accepted: 07/25/2023] [Indexed: 09/13/2023]
Abstract
BACKGROUNDS Henoch-Schönlein purpura (IgA vasculitis) is the most common childhood vasculitis, one of its complications is renal involvement. However, several treatment regimens have been proposed to improve renal function in the long term, but which drug regimen can be most effective is still controversial. METHODS This study was a systematic review. In order to find evidence related to the purpose of this study, databases including Google Scholar, Web of Science, ProQuest and Medline via PubMed, and Scopus were searched with the appropriate keywords. QUADAS-2 (a Quality Assessment tools for Diagnostic Accuracy Studies) checklist was also used to evaluate the quality of studies. Based on the keywords used in reviewing the information sources of scientific articles, in the first stage, 86 studies were included in the review. Taking into account characteristics such as lack of homogeneity with the objectives of the present study, finally, 11 studies were selected for analysis and final evaluation. RESULTS A total of 11 studies, including 722 patients in the age range of 5.5 to 9.9 years with HSP were included in the study. The follow-up period of the patients varied from 6 months to 16 years in terms of examining the treatment process. In terms of study type, 7 studies were conducted as prospective or retrospective (non-interventional) cohorts and 4 studies as randomized clinical trials. The treatment regimen of injectable methylprednisolone followed by oral prednisolone resulted in a long-term recovery of 79.2% (95% confidence interval between 0.66% and 88.2%); however, the need for additional immunosuppressive in two studies was mentioned as 38% and 46.1%, respectively. In the therapeutic regimen of oral methylprednisolone alone, a significant improvement in long-term renal function was achieved in comparison with placebo. Administration of injectable methylprednisolone followed by cyclosporine A had the highest effectiveness in terms of improving renal function in the long term. CONCLUSION Regimes based on the administration of prednisolone (either oral or injectable, either as a single drug or as a combination) lead to long-term improvement of renal function in patients with HSP, but the use of other immunosuppressive drugs such as cyclosporine A, of course, with optimizing the drug dose can lead to a significant improvement in the clinical performance.

Abstract
BACKGROUND IgA vasculitis (IgAV), previously known as Henoch-Schönlein purpura, is the most common vasculitis of childhood but may also occur in adults. This small vessel vasculitis is characterised by palpable purpura, abdominal pain, arthritis or arthralgia and kidney involvement. This is an update of a review first published in 2009 and updated in 2015. OBJECTIVES To evaluate the benefits and harms of different agents (used singularly or in combination) compared with placebo, no treatment or any other agent for (1) the prevention of severe kidney disease in people with IgAV with or without kidney involvement at onset, (2) the treatment of established severe kidney disease (macroscopic haematuria, proteinuria, nephritic syndrome, nephrotic syndrome with or without acute kidney failure) in IgAV, and (3) the prevention of recurrent episodes of IgAV-associated kidney disease. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies up to 2 February 2023 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing interventions used to prevent or treat kidney disease in IgAV compared with placebo, no treatment or other agents were included. DATA COLLECTION AND ANALYSIS Two authors independently determined study eligibility, assessed the risk of bias and extracted data from each study. Statistical analyses were performed using the random-effects model, and the results were expressed as risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes with 95% confidence intervals (CI). Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS Twenty studies (1963 enrolled participants) were identified; one three-arm study has been assessed as two studies. Nine studies were at low risk of bias for sequence generation (selection bias), and nine studies were at low risk of bias for allocation concealment (selection bias). Blinding of participants and personnel (performance bias) and outcome assessment (detection bias) was at low risk of bias in four and seven studies, respectively. Nine studies reported complete outcome data (attrition bias), while 10 studies reported expected outcomes, so were at low risk of reporting bias. Five studies were at low risk of other bias. Eleven studies evaluated therapy to prevent persistent kidney disease in IgAV with or without kidney involvement at presentation. There was probably no difference in the risk of persistent kidney disease any time after treatment (5 studies, 746 children: RR 0.74, 95% CI 0.42 to 1.32) or at one, three, six and 12 months in children given prednisone for 14 to 28 days at presentation of IgAV compared with placebo or supportive treatment (moderate certainty evidence). There may be no differences in the risk of any persistent kidney disease with antiplatelet therapy (three studies) or heparin (two studies) in children with or without any kidney disease at study entry, although heparin may reduce the risk of proteinuria by three months compared with placebo or no specific treatment (2 studies, 317 children: RR 0.47, 95% CI 0.31 to 0.73). One study comparing montelukast with placebo found no differences in outcomes as assessed by severity scale scores. Nine studies examined the treatment of severe IgAV-associated kidney disease. In two studies (one involving 56 children and the other involving 54 adults), there may be no differences in efficacy outcomes or adverse effects with cyclophosphamide compared with placebo or supportive treatment. In two studies, there may be no differences in the numbers achieving remission of proteinuria with intravenous (IV) cyclophosphamide compared with mycophenolate mofetil (MMF) (65 children evaluated) or tacrolimus (142 children evaluated). In three small studies comparing cyclosporin with methylprednisolone (15 children), MMF with azathioprine (26 children), or MMF with leflunomide (19 children), it is unclear whether the treatment had any effect on the numbers in remission or the degree of proteinuria between treatment groups because of small numbers of included participants. In one study comparing plasmapheresis, cyclophosphamide and methylprednisolone with cyclophosphamide and methylprednisolone, there may be no difference in the numbers achieving remission. One study compared fosinopril with no specific therapy and reported fosinopril reduced the number of participants with proteinuria. No studies were identified that evaluated the efficacy of therapy on kidney disease in participants with recurrent episodes of IgAV. AUTHORS' CONCLUSIONS There are no substantial changes in conclusions from this update compared with the initial review or the previous update despite the addition of five studies. From generally low to moderate certainty evidence, we found that there may be little or no benefit in the use of corticosteroids or antiplatelet agents to prevent persistent kidney disease in children with IgAV in participants with no or minimal kidney involvement at presentation. We did not find any studies which evaluated corticosteroids in children presenting with IgAV and nephritic and/or nephrotic syndrome, although corticosteroids are recommended in such children in guidelines. Though heparin may be effective in reducing proteinuria, this potentially dangerous therapy is not justified to prevent serious kidney disease when few children with IgAV develop severe kidney disease. There may be no benefit of cyclophosphamide compared with no specific treatment or corticosteroids. While there may be no benefit in the efficacy of MMF or tacrolimus compared with IV cyclophosphamide in children or adults with IgAV and severe kidney disease, adverse effects, particularly infections, may be lower in MMF or tacrolimus-treated children. Because of small patient numbers and events leading to imprecision in results, it remains unclear whether cyclosporin, MMF or leflunomide have any role in the treatment of children with IgAV and severe kidney disease. We did not identify any studies which evaluated corticosteroids.

Abstract
QUESTION A few patients have previously presented to my clinic with palpable purpura, joint inflammation, and severe abdominal pain characteristic of Henoch-Schönlein purpura (HSP). Considering that renal injury is the primary long-term complication of HSP, are corticosteroids effective in preventing or treating renal disease in children with HSP? ANSWER Henoch-Schönlein purpura is self-limiting in 94% of children, but permanent renal injury is reported in one-fifth of children with nephritic or nephrotic features. Corticosteroids have been considered as candidates for preventing and treating renal involvement in HSP. There is a moderate level of evidence to suggest corticosteroids are not effective in preventing renal involvement in HSP. However, based on low-level evidence and similarities with primary immunoglobulin A nephropathy, experts recommend corticosteroids in treating renal involvement in HSP to prevent long-term kidney injury. Dose and duration of therapy should be carefully considered in consultation with a pediatric nephrologist.

Abstract
Henoch-Schönlein purpura nephritis and immunoglobulin A nephropathy are common glomerulopathies in the pediatric population that deserve special attention. In some cases the primary care provider can follow the patient but others need more intensive management. Delaying this treatment can lead to worse morbidity. This article provides information on the pathogenesis, outcomes, and follow-up strategies that will aid in the diagnosis and referral of patients at risk for kidney disease.

Abstract
A 64-year-old man was admitted to our hospital for purpuric rash, joint pain, and a fever. He had earlier undergone a follow-up examination for interstitial lung disease. At the current visit, the diagnosis was immunoglobulin A (IgA) vasculitis, based on skin and renal biopsy findings. He developed sudden breathlessness and hemoptysis. Chest computed tomography revealed ground glass opacity in the right lower lung fields, suggesting pulmonary hemorrhaging associated with IgA vasculitis. Despite steroid and cyclophosphamide therapy, and plasma exchange, he died 52 days after admission. Early aggressive therapies may be recommended for old patients with IgA vasculitis who have an additional comorbidities.

Abstract
BACKGROUND Henoch-Schӧnlein purpura (HSP) is a common vasculitis of childhood. Though HSP is usually self-limiting, severe complications can occur. The management for this condition has not been established yet. Thus, this nationwide study aimed at investigating epidemiological characteristics of children with HSP in Korea. The patterns of clinical practice with regard to the complications of the condition were also investigated. METHODS This is a national population-based study that used the National Health Insurance Database. Children below 18 years who were diagnosed with HSP in Korea between 2006 and 2015 were enrolled. Data, such as age, sex, yearly and monthly distribution of HSP, hospitalization, re-hospitalization, comorbidities, and interventions were obtained. The use of steroids was also analyzed. RESULTS A total of 56,841 children were enrolled. The annual incidence of HSP was 55.9 per 100,000 children. The peak age was 5 years. Spring was the most prevalent season. Sex (male) and young age (< 9 years) were risk factors of hospitalization. Younger children were more likely to be re-hospitalized and suspected with intussusception, arthritis, and nephritis. Only 4 children received laparotomy. In total, 57% were managed with steroids, and mean durations of medication were 4-5 days. Children who were hospitalized and those with comorbidities used steroids more frequently (P < 0.001). CONCLUSION The annual incidence of HSP is 55.9 per 100,000 children which is higher in Korea than that in other countries. Younger children can have a more severe clinical course. This nationwide survey provides valuable information to understand HSP in children and to inspire further research on HSP.

Abstract
OBJECTIVE The treatment of Henoch-Schönlein purpura (HSP) with moderate proteinuria remains controversial. We retrospectively analyzed the efficacy of immune suppressants, with a particular emphasis on mycophenolate mofetil (MMF). METHODS Ninety-five HSP patients with moderate proteinuria (1.0-3.5 g/24 h) after at least three months of therapy with angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) were divided into three groups: an MMF group (n=33) that received MMF 1.0-1.5 g/d combined with prednisone (0.4-0.5 mg/(kg·d)), a corticosteroid (CS) group (n=31) that received full-dose prednisone (0.8-1.0 mg/(kg·d)), and a control group (n=31). Patients in the MMF and CS groups continued to take ACEI or ARB at the original dose. The patients in the control group continued to take ACEI or ARB but the dose was increased by (1.73±0.58)-fold. The patients were followed up for 6-78 months (median 28 months). RESULTS The baseline proteinuria was higher in the MMF group ((2.1±0.9) g/24 h) than in the control group ((1.6±0.8) g/24 h) (P=0.039). The proteinuria decreased significantly in all groups during follow-up, but only in the MMF group did it decrease significantly after the first month. At the end of follow-up, the proteinuria was (0.4±0.7) g/24 h in the MMF group and (0.4±0.4) g/24 h in the CS group, significantly lower than that in the control group ((0.9±1.1) g/24 h). The remission rates in the MMF group, CS group, and control group were respectively 72.7%, 71.0%, and 48.4% at six months and 72.7%, 64.5%, and 45.2% at the end of follow-up. The overall number of reported adverse events was 17 in the MMF group, 30 in the CS group, and 6 in the control group (P<0.001). CONCLUSIONS MMF with low-dose prednisone may be as effective as full-dose prednisone and tend to have fewer adverse events. Therefore, it is probably superior to conservative treatments of adult HSP patients with moderate proteinuria.

Abstract
BACKGROUND Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood but may occur in adults. This small vessel vasculitis is characterised by palpable purpura, abdominal pain, arthritis or arthralgia and kidney involvement. This is an update of a review first published in 2009. OBJECTIVES To evaluate the benefits and harms of different agents (used singularly or in combination) compared with placebo, no treatment or any other agent for: (1) the prevention of severe kidney disease in patients with HSP without kidney disease at presentation; (2) the prevention of severe kidney disease in patients with HSP and minor kidney disease (microscopic haematuria, mild proteinuria) at presentation; (3) the treatment of established severe kidney disease (macroscopic haematuria, proteinuria, nephritic syndrome, nephrotic syndrome with or without acute kidney failure) in HSP; and (4) the prevention of recurrent episodes of HSP-associated kidney disease. SEARCH METHODS We searched the Cochrane Kidney and Transplant's Specialised Register to 13 July 2015 through contact with the Trials Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing interventions used to prevent or treat kidney disease in HSP compared with placebo, no treatment or other agents were included. DATA COLLECTION AND ANALYSIS Two authors independently determined study eligibility, assessed risk of bias and extracted data from each study. Statistical analyses were performed using the random effects model and the results were expressed as risk ratio (RR) or risk difference (RD) for dichotomous outcomes and mean difference (MD) for continuous outcomes with 95% confidence intervals (CI). MAIN RESULTS Thirteen studies (1403 enrolled patients) were identified. Risks of bias attributes were frequently poorly performed. Low risk of bias was reported in six studies (50%) for sequence generation (selection bias) and in seven (58%) for allocation concealment (selection bias). Blinding of participants and personnel (performance bias) and of outcome assessment (detection bias) was at low risk of bias in three studies. Five studies reported complete outcome data (attrition bias) while eight studies reported expected outcomes so were at low risk of reporting bias.Eight studies evaluated therapy to prevent persistent kidney disease in HSP. There was no significant difference in the risk of persistent kidney disease any time after treatment (5 studies, 746 children: RR 0.74, 95% CI 0.42 to 1.32), or at one, three, six and 12 months in children given prednisone for 14 to 28 days at presentation of HSP compared with placebo or supportive treatment. There were no significant differences in the risk of persistent kidney disease with antiplatelet therapy in children with or without kidney disease at entry. Heparin significantly reduced the risk of persistent kidney disease by three months compared with placebo (1 study, 228 children: RR 0.27, 95% CI 0.14 to 0.55); no significant bleeding occurred. Four studies examined the treatment of severe HSP-associated kidney disease. Two studies (one involving 56 children and the other involving 54 adults) compared cyclophosphamide with placebo or supportive treatment and found no significant benefit of cyclophosphamide. There were no significant differences in adverse effects. In one study comparing cyclosporin with methylprednisolone (15 children) there was no significant difference in remission at final follow-up at a mean of 6.3 years (RR 1.37, 95% CI 0.74 to 2.54). In one study (17 children) comparing mycophenolate mofetil with azathioprine, there was no significant difference in the remission of proteinuria at one year (RR 1.32, 95% CI 0.86 to 2.03). No studies were identified which evaluated the efficacy of therapy on kidney disease in participants with recurrent episodes of HSP. AUTHORS' CONCLUSIONS There are no substantial changes in conclusions from this update compared with the initial review. From generally low quality evidence, we found no evidence of benefit from RCTs for the use of prednisone or antiplatelet agents to prevent persistent kidney disease in children with HSP. Though heparin appeared effective, this potentially dangerous therapy is not justified to prevent serious kidney disease when fewer than 2% of children with HSP develop severe kidney disease. No evidence of benefit has been found for cyclophosphamide treatment in children or adults with HSP and severe kidney disease. Because of small patient numbers and events leading to imprecision in results, it remains unclear whether cyclosporin and mycophenolate mofetil have any roles in the treatment of children with HSP and severe kidney disease.

Immunoglobulin A (IgA) vasculitis, formerly called Henoch-Schönlein purpura, is an immune complex vasculitis affecting small vessels with dominant IgA deposits. Clinical manifestations mainly involve cutaneous purpura, arthralgias and/or arthritis, acute enteritis and glomerulonephritis. IgA vasculitis is more common among children than adults, with more severe disease in adults. Gastrointestinal and renal involvements represent the principal causes of morbidity and mortality in adults. Factors associated with long-term end-stage renal disease (ESRD) include baseline renal function impairment and baseline proteinuria >1 or 1.5 g/day, and on renal biopsy degree of interstitial fibrosis, sclerotic glomeruli and fibrinoid necrosis. Management of IgA vasculitis in adults is rendered difficult for clinicians because of the absence of correlation between initial presentation and long-term renal outcome, and the possible occurrence of spontaneous remission in patients with severe presentation or, in contrast, possible evolution to ESRD in patients with mild symptoms. Treatment is often symptomatic because disease course is usually benign. Treatment of severe involvement, including severe gastrointestinal complications or proliferative glomerulonephritis, remains controversial, with no evidence that corticosteroids or immunosuppressive agents improved long-term outcome. Prospective, randomized, controlled trials are thus needed to analyze the benefit-risk ratio of such treatments.

Abstract
Henoch-Schönlein purpura (HSP) is a systemic disorder characterized by leukocytoclastic vasculitis involving the capillaries and the deposition of IgA immune complexes. Renal involvement is the principal cause of morbidity and mortality in children with HSP. Thus, it is important to clarify the onset mechanism as well as the prognostic factors of Henoch-Schönlein purpura nephritis (HSPN) and to identify the most appropriate treatment. We herein review the pathogenesis, the prognostic factors and treatment of HSPN. As to the pathogenesis, several studies suggest that galactose-deficient IgA1 (Gd-IgA1) is recognized by anti-glycan antibodies, leading to the formation of circulating immune complexes and their mesangial deposition, thereby inducing renal injury. With regard to the prognostic factors, a number of factors have been suggested including nephrotic syndrome, decreased factor XIII activity, hypertension, severe renal injury, high renal accumulation of activated macrophage, alpha-smooth muscle actin, and high serum myeloid-related protein levels. For the treatment of severe HSPN, aggressive therapies including multiple drug combination therapy and plasmapheresis have been shown to be effective in ameliorating proteinuria and histological severity. Nevertheless, detailed investigation into the pathogenesis of HSPN and double-blind randomized control studies on children with HSPN are still necessary.

Abstract
BACKGROUND The long-term prognosis of Henoch-Schönlein Purpura (HSP) is predominantly determined by the extent of renal involvement. There is no consensus as to whether treatment with prednisolone at presentation can prevent or ameliorate the progression of nephropathy in HSP. METHODS Children under 18 years of age with new-onset HSP were randomly assigned to receive prednisolone or placebo for 14 days. The primary outcomes were (a) the presence of proteinuria at 12 months (defined as urine protein : creatinine ratio (UP : UC) >20 mg/mmol) and (b) the need for additional treatment (defined as the presence of hypertension requiring treatment or renal biopsy anomalies or the need for treatment of renal disease) during the 12 month study period. RESULTS 352 children were randomised. Of those patients with laboratory UP : UC results available at 12 months, 18/123 (15%) patients on prednisolone and 13/124 (10%) patients on placebo had UP : UC >20 mg/mmol. There was no significant difference in the proportion of patients with UP : UC >20 mg/mmol at 12 months between the treatment groups (OR (prednisolone/placebo)=1.46, 95% CI 0.68 to 3.14, n=247), even after adjusting for baseline proteinuria and medications known to affect proteinuria (adjusted OR=1.29, 95% CI 0.58 to 2.82, n=247). Similarly, there was no significant difference in the time needed for additional treatment between the two groups (hazard ratio (HR) (prednisolone/placebo)=0.53, 95% CI 0.18 to 1.59, n=323). CONCLUSIONS This is the largest trial of the role of steroids in children with HSP. We found no evidence to suggest that early treatment with prednisolone reduces the prevalence of proteinuria 12 months after disease onset in children with HSP. TRIAL REGISTRATION NUMBER ISRCTN71445600.

Abstract
Central nervous system vasculitides in children may develop as a primary condition or secondary to an underlying systemic disease. Many vasculitides affect both adults and children, while some others occur almost exclusively in childhood. Patients usually present with systemic symptoms with single or multiorgan dysfunction. The involvement of central nervous system in childhood is not frequent and it occurs more often as a feature of subtypes like childhood polyarteritis nodosa, Kawasaki disease, Henoch Schönlein purpura, and Bechet disease. Primary angiitis of the central nervous system of childhood is a reversible cause of severe neurological impairment, including acute ischemic stroke, intractable seizures, and cognitive decline. The first line therapy of CNS vasculitides is mainly based on corticosteroids and immunosuppressor drugs. Other strategies include plasmapheresis, immunoglobulins, and biologic drugs. This paper discusses on current understanding of most frequent primary and secondary central nervous system vasculitides in children including a tailored-diagnostic approach and new evidence regarding treatment.

Outcome of Henoch-Schönlein purpura 8 years after treatment with a placebo or prednisone at disease onset. Pediatr Nephrol 2012; 27:933-9.

Abstract
BACKGROUND Corticosteroids have been shown not to prevent the development of Henoch-Schönlein nephritis. However, long-term follow-up data are scarce. METHODS The long-term outcome of patients in a randomized placebo-controlled prednisone study was evaluated 8 years later with a health questionnaire completed by 160/171 (94%) patients and by urine and blood pressure screening (138/171, 81%). RESULTS Twelve patients had hematuria and/or proteinuria and seven had hypertension. The patients with nephritis at onset of Henoch-Schönlein purpura (HSP) had an increased risk of hypertension and/or urine abnormalities (odds ratio 3.6, p = 0.022, 95% confidence interval 1.3-10.0). There were no differences between the prednisone and placebo groups. Recurrences of purpura were reported by 15 patients, with some recurrences continuing for 10 years. All five reported pregnancies were complicated by proteinuria. Four patients presented with hematuria and/or proteinuria at the control visit, and four had hypertension. Of these, two had a decreased estimated glomerular filtration rate. CONCLUSIONS HSP has a good long-term prognosis in unselected patients, although skin relapses with/without late-onset nephritis may occur, even a decade after the initial disease. Urine and blood pressure abnormalities 8 years after HSP are associated with nephritis at its onset. Early prednisone treatment does not affect the outcome and should not be routinely used.

Abstract
OBJECTIVE To characterize the effect of corticosteroid exposure on clinical outcomes in children hospitalized with new-onset Henoch-Schönlein purpura (HSP). PATIENTS AND METHODS We conducted a retrospective cohort study of children discharged with an International Classification of Diseases, Clinical Modification code of HSP between 2000 and 2007 by using inpatient administrative data from 36 tertiary care children's hospitals. We used stratified Cox proportional hazards regression models to estimate the relative effect of time-varying corticosteroid exposure on the risks of clinical outcomes that occur during hospitalization for acute HSP. RESULTS During the 8-year study period, there were 1895 hospitalizations for new-onset HSP. After multivariable regression modeling adjustment, early corticosteroid exposure significantly reduced the hazard ratios for abdominal surgery (0.39 [95% confidence interval (CI): 0.17-0.91]), endoscopy (0.27 [95% CI: 0.13-0.55]), and abdominal imaging (0.50 [95% CI: 0.29-0.88]) during hospitalization. CONCLUSIONS In the hospital setting, early corticosteroid exposure was associated with benefits for several clinically relevant HSP outcomes, specifically those related to the gastrointestinal manifestations of the disease.

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
Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood. In this review, the main clinical features and complications are described. Although most features are self-limiting, renal disease is the most likely to result in long-term morbidity. Treatment of HSP nephritis is controversial, and the evidence for both prevention and treatment of established disease is reviewed. Follow-up for children presenting with HSP should be for at least 6 months and should include regular urine testing for proteinuria and haematuria and a blood pressure measurement. Women with a history of HSP during childhood are at increased risk of complications (such as proteinuria and hypertension) during pregnancy and should be monitored closely. This paper describes current practice with regard to investigation and management and proposes a practical care pathway of the management of a child with HSP.

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
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
Leukocytoclastic vasculitis (LcV) is the most common form of vasculitis of the skin and usually results from deposition of immune complexes at the vessel wall. It presents in different forms and in association with different diseases. When IgA is the dominant immunoglobulin in immune complexes, systemic involvement is likely in both children and adults (Henoch-Schönlein purpura--HSP). LcV due to IgG- or IgM-containing immune complexes has less systemic involvement and a better prognosis than HSP. Other forms of LcV include cryoglobulinaemic, urticarial and ANCA-associated LcV as well as LcV associated with vasculopathy and coagulopathy in SCLE/SLE or in bacteraemia/sepsis. The aim of diagnostic guidelines is to determine the specific type and systemic involvement of LcV and to identify an underlying cause. Basic work-up should encompass history of drug intake and of preceding infections, biopsy with immunofluorescence, differential blood count, urine analysis and throat swabs. Therapy of immune complex LcV often does not require aggressive therapy due to a usually favourable course. It includes avoidance or treatment of eliciting agents and use of compression stockings to reduce purpura. There are no large prospective randomized controlled studies. Corticosteroids are indicated when there are signs of incipient skin necrosis. In chronic or relapsing LcV we suggest colchicine as a first-line and dapsone as a second-line therapy. Corticosteroids may reduce the incidence of severe renal insufficiency in children according to some studies, but there is no study showing such an effect in adults. Severe systemic vasculitis requires immunosuppressive strategies.

Abstract
BACKGROUND To determine the benefits and harms of therapies used to prevent or treat kidney disease in Henoch-Schönlein Purpura (HSP). OBJECTIVES To evaluate the benefits and harms of different agents (used singularly or in combination) compared with placebo or no treatment or another agent for the prevention or treatment of kidney disease in patients with HSP. SEARCH STRATEGY Randomised controlled trials (RCTs) and quasi-RCTs were identified from the Cochrane Renal Group's specialised register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE using optimally sensitive search strategies combined with search terms for HSP. SELECTION CRITERIA RCTs comparing any intervention used to prevent or treat kidney disease in HSP compared with placebo, no treatment or other agents were included. DATA COLLECTION AND ANALYSIS Three authors independently assessed trial quality and extracted data from each study. Statistical analyses were performed using the random effects model and the results were expressed as risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes with 95% confidence intervals (CI). MAIN RESULTS Ten studies (1230 children) were identified. There was no significant difference in the risk of persistent kidney disease at six months (3 studies, 379 children: RR 0.51, 95% CI 0.24 to 1.11) and 12 months (3 studies, 498 children: RR 1.02, 95% CI 0.40 to 2.62) in children given prednisone for 14 to 28 days at presentation of HSP compared with placebo or supportive treatment. In children with severe kidney disease, there was no significant difference in the risk of persistent kidney disease with cyclophosphamide compared with supportive treatment (1 study, 56 children: RR 1.07, 95% CI 0.65 to 1.78) and with cyclosporin compared with methylprednisolone (1 study, 19 children: RR 0.39, 95% CI 0.14 to 1.06). AUTHORS' CONCLUSIONS Data from RCTs for any intervention used in improve kidney outcomes in children with HSP are very sparse except for short-term prednisone. There was no evidence of benefit of prednisone in preventing serious long-term kidney disease in HSP.

Gastrointestinal manifestations of Henoch-Schonlein Purpura. Dig Dis Sci 2008; 53:2011-9.

Abstract
Henoch-Schonlein Purpura (HSP) is the most common systemic vasculitis in childhood. The diagnostic criteria include palpable purpura with at least one other manifestation -- abdominal pain, IgA deposition, arthritis or arthralgia, or renal involvement. Immune complex deposits result in necrosis of the wall of small- and medium-sized arteries with infiltration of tissue by neutrophils and deposition of nuclear fragments, a process called leukocytoclastic vasculitis (LCV). It is often associated with infections, medications, or tumors. It may coexist with or mimic Crohn's disease. Periumbilical and epigastric pain worsens with meals, from bowel angina. Bleeding is usually occult or, less commonly, associated with melena. Intussusception, the most common surgical complication, is usually ileo-ileo or ileo-colic. Perforations, usually ileal, may occur spontaneously or be associated with intussusception. Ultrasound, recommended as the first diagnostic test, and CT scans may show intussusception and asymmetric bowel wall thickening mainly involving the jejunum and ileum. There are a range of endoscopic findings including gastritis, duodenitis, ulceration, and purpura, with the second portion of the duodenum characteristically being involved more than the bulb. Intestinal biopsies show IgA deposition and LCV in the submucosal vessels. Superficial biopsies may show inflammation, ulceration, edema, hemorrhage, and vascular congestion, presumably due to vasculitis-induced mucosal ischemia. The efficacy of corticosteroids in preventing severe complications or relapses is controversial. The majority of patients, however, improve spontaneously.

Abstract
OBJECTIVE No consensus exists among general pediatricians or pediatric rheumatologists regarding whether corticosteroid therapy ameliorates the acute manifestations of Henoch-Schönlein purpura or mitigates renal injury. Therefore, we sought to synthesize the reported experimental and observational data regarding corticosteroid use. METHODS We performed a meta-analysis based on a comprehensive review of the literature in the Medline database (1956 to January 2007) and the Cochrane Controlled Trials Register. On the basis of reported outcomes among patients with Henoch-Schönlein purpura who were treated at diagnosis with corticosteroids compared with patients treated with supportive care only, we calculated odds ratios for the resolution of abdominal pain, the need for surgical intervention secondary to severe pain or intussusception, the likelihood of Henoch-Schönlein purpura recurrence, and the development of transient or persistent renal disease. RESULTS Of 201 articles retrieved from the initial literature search, 15 were eligible for inclusion. Corticosteroid treatment did not reduce the median time to resolution of abdominal pain but did significantly reduce the mean resolution time and increased the odds of resolution within 24 hours. Early corticosteroid treatment significantly reduced the odds of developing persistent renal disease. In addition, although the results were not statistically significant, the prospective data suggest reduced odds of both surgical intervention and recurrence. CONCLUSIONS Corticosteroids, given early in the course of illness, seem to produce consistent benefits for several major clinically relevant Henoch-Schönlein purpura outcomes.

Abstract
Henoch-Schönlein purpura (HSP) frequently occurs in children below the age of 15 years and is rare with increasing age. Prognosis and therapy largely depend on the clinical presentation. The disease may be preceded by an upper respiratory tract infection, and drugs have also been implicated in the pathogenesis of the disease. Most children recover from the illness, whereas 40% of adults have persistent hematuria and 10% develop chronic renal failure. Recent studies strongly suggest that adults with HSP should be monitored for prolonged periods and treated aggressively. Here, we present a case of a patient with HSP who developed multiorgan failure requiring assistance in breathing and dialysis, and also sustained gastrointestinal bleeding despite aggressive immunosuppressive therapy. In analogy to published data in children with severe HSP, the patient was treated by plasma exchange in combination with low dose oral cyclophosphamide, while high dose steroids were reduced over time. The patient could be discharged 70 days after admission. One year after discharge, the patient is doing well without any signs of activity of HSP and completely unremarkable renal function. The maintenance daily dose of steroids is 7.5 mg.

Abstract
OBJECTIVE To evaluate the efficacy of early prednisone therapy in preventing renal and treating extrarenal and renal symptoms in Henoch-Schönlein purpura (HSP) in a placebo-controlled trial. STUDY DESIGN A total of 171 patients (84 treated with prednisone and 87 receiving placebo) were included and followed up for 6 months. The endpoints were renal involvement at 1, 3, and 6 months and healing of extrarenal symptoms. The analyses were performed on an intent-to-treat basis. RESULTS Prednisone (1 mg/kg/day for 2 weeks, with weaning over the subsequent 2 weeks) was effective in reducing the intensity of abdominal pain (pain score, 2.5 vs 4.8; P = .029) and joint pain (4.6 vs 7.3; P = .030). Prednisone did not prevent the development of renal symptoms but was effective in treating them; renal symptoms resolved in 61% of the prednisone patients after treatment, compared with 34% of the placebo patients (difference = 27%; 95% confidence interval = 3% to 47%; P = .024). CONCLUSIONS The general use of prednisone in HSP is not supported, but patients with disturbing symptoms may benefit from early treatment, because prednisone reduces extrarenal symptoms and is effective in altering (but not preventing) the course of renal involvement.

Abstract
BACKGROUND In paediatric clinical practice treatment is often adjusted in relation to body size, for example the calculation of pharmacological and dialysis dosages. In addition to use of body weight, for some purposes total body water (TBW) and surface area are estimated from anthropometry using equations developed several decades previously. Whether such equations remain valid in contemporary populations is not known. METHODS Total body water was measured using deuterium dilution in 672 subjects (265 infants aged <1 year; 407 children and adolescents aged 1-19 years) during the period 1990-2003. TBW was predicted (a) using published equations, and (b) directly from data on age, sex, weight, and height. RESULTS Previously published equations, based on data obtained before 1970, significantly overestimated TBW, with average biases ranging from 4% to 11%. For all equations, the overestimation of TBW was greatest in infancy. New equations were generated. The best equation, incorporating log weight, log height, age, and sex, had a standard error of the estimate of 7.8%. CONCLUSIONS Secular trends in the nutritional status of infants and children are altering the relation between age or weight and TBW. Equations developed in previous decades significantly overestimate TBW in all age groups, especially infancy; however, the relation between TBW and weight may continue to change. This scenario is predicted to apply more generally to many aspects of paediatric clinical practice in which dosages are calculated on the basis of anthropometric data collected in previous decades.

Abstract
BACKGROUND The duration of follow up to assess the risk of long term renal impairment in Henoch-Schönlein purpura (HSP) without nephritic or nephrotic syndrome or renal failure on diagnosis remains undetermined. AIMS To undertake a systematic review of the literature to assess whether the risk of long term renal impairment without renal involvement on diagnosis could be estimated and to determine the time period when renal involvement is very unlikely after the diagnosis of HSP. METHODS Search of studies of unselected children with HSP, and available information on urinary findings, renal involvement, and long term renal function follow up. Studies of selected children with HSP nephropathy at diagnosis were excluded. RESULTS Twelve studies of 1133 children were reviewed. The follow up period ranged from 6 weeks to 36 years. Proteinuria and/or haematuria, which occurred in 34.2%, of which only one fifth were in association with nephritic or nephrotic syndrome, developed in 85% of cases within 4 weeks of the diagnosis of HSP, in 91% within 6 weeks, and in 97% within 6 months. Permanent renal impairment never developed after normal urinalysis; it occurred in 1.6% of those with isolated urinary abnormalities, and in 19.5% of those who developed nephritic or nephrotic syndrome. CONCLUSION No long term renal impairment occurred after normal urinalysis. Even if urinalysis is normal at presentation, the testing should be continued for six months. There is no need to follow up after the first six months those whose urinalysis remains normal.

Abstract
Palpable purpura, the inflammation of blood vessels is the hallmark of vasculitis. It can be observed in a variety of settings, where vessels can be affected primarily or as a secondary event. Every patient with vasculitis should be considered to have a systemic disease unless proven otherwise. One or more systemic symptoms occur in at least 50% of patients and there is no way to predict systemic involvement. Patients may demonstrate mild systemic involvement like arthralgia and arthritis, fever and malaise or more severe symptoms such as massive proteinuria and raised creatinine leading to chronic renal failure, severe intestinal bleeding or perforation with a fatal outcome. In this article we will review the life-threatening aspects of purpura and vasculitis.

Abstract
BACKGROUND Henoch-Schonlein purpura (HSP) is a vasculitic syndrome with palpable purpura and renal involvement. The treatment for HSP with persistent renal disease remains controversial. The kidney biopsy in HSP shows IgA deposits and fish-oil therapy has proven to be promising in halting the progression of IgA nephropathy. METHODS Five children with biopsy-proven HSP with repeated episodes of haematuria and proteinuria were treated with fish oil (1 g orally twice daily). In three of the five patients an angiotensin-converting enzyme inhibitor (ACEI) was added for hypertension. RESULTS The mean duration of follow up after starting fish-oil therapy was 49.2 weeks. The protein excretion rate prior to starting fish oil was 1041 mg/day and on the last follow-up visit the rate had decreased to 104 mg/day (P <0.05). The average blood pressure (BP) prior to therapy was 135/82. On the last follow-up visit the average BP off ACEI had decreased to 100/54 (P <0.05). After a year of follow up serum creatinine and glomerular filtration rates have remained stable at 51.2 micromol/L and 128 mL/min/1.73 m2, respectively. CONCLUSION This is the first report of abatement of HSP with fish oil and ACEI in children. There is a need for randomized prospective trials to confirm this observation.

Abstract
The pediatric IgA nephropathies are IgA nephrothapy (Berger's Disease) and Henoch-Schönlein purpura nephritis. Both conditions are reviewed in detail with respect to epidemiology, clinical features, outcome, prognostic markers, and therapeutic approaches. For both conditions variable disease severity and outcome along with the lack of conclusive evidence for efficacy of treatment based on randomized clinical trials makes it difficult to make strong recommendations regarding therapy.

Abstract
OBJECTIVE To describe pulmonary involvement in Henoch-Schönlein purpura (HSP). PATIENTS AND METHODS We retrospectively reviewed the medical records of patients with HSP who were seen at the Mayo Clinic in Rochester, Minn, during a 6-year period (January 1, 1997, to December 31, 2002). Patients with HSP and pulmonary involvement were identified through a review of clinical records, radiological studies, pulmonary function data, and lung biopsy findings. RESULTS We identified 124 patients with HSP during the study period; 72 (58.1%) were males. The median age was 15 years (range, 8 months to 81 years). Among the 124 patients with HSP, 3 (2.4%), all adults, had pulmonary involvement. Of these 3 patients, aged 20, 67, and 76 years, 2 were women. Pulmonary manifestations consisted of diffuse alveolar hemorrhage (DAH) (2 patients) and usual interstitial pneumonia that improved with corticosteroid therapy (1 patient). CONCLUSIONS Pulmonary involvement in HSP is rare. It occurs more often in adults and commonly manifests as DAH and occasionally as usual interstitial pneumonia or interstitial fibrosis. Our cases and previously reported cases suggest that DAH is the most common manifestation of pulmonary involvement in HSP.

Abstract
BACKGROUND Henoch Schönlein Purpura (HSP) is the most common systemic vasculitis of childhood. There is considerable controversy over whether children with HSP should be treated with corticosteroids. The goal of this study was to investigate whether early corticosteroid administration could reduce the rate of renal or gastrointestinal complications in children with HSP. METHODS Forty children with HSP, seen in the emergency room of a tertiary-care, paediatric centre, entered a randomized, double-blind, placebo controlled study. The treatment group (n = 21) received oral prednisone, 2 mg/kg/day for one week, with weaning over a second week, while the placebo group (n = 19) received an identical appearing placebo. Co-primary outcomes were the rate of renal involvement at one year and the rate of acute gastrointestinal complications. Co-primary outcomes were analysed using Fisher's Exact test. RESULTS At one year, there was no difference in the rate of renal involvement (3/21 prednisone group vs. 2/19 placebo group, P = 1.0). There was also no statistically significant difference in the rate of acute gastrointestinal complications (2/21 prednisone group vs. 3/19 placebo group, P = 0.7). Two children in the placebo group did experience intussusceptions compared with none in the prednisone group (P = 0.2). CONCLUSIONS Early prednisone therapy in HSP does not appear to reduce the risk of renal involvement at one year, or the risk of acute gastrointestinal complications. There may be a reduced risk of intussusception. The routine, early use of prednisone in uncomplicated HSP cannot be recommended at this time.

Abstract
Nephritis in Henoch-Schönlein purpura (HSP) is the primary cause of morbidity and mortality. Although many therapeutic regimens have been reported to be effective, no therapy has been shown in a controlled trial to be beneficial. Fifty-six patients with histopathologically severe HSP nephritis were randomized to receive supportive therapy with or without cyclophosphamide, 90 mg/m(2)/day for 42 days. Patients were classified according to status at final follow-up: Fully Recovered 48.2%, Persistent Abnormalities 39.3%, or ESRD/Death 12.5%. There were no differences in onset data or outcome between the two trial groups or in outcome between trial and 23 non-trial patients followed concurrently. Therefore, data from trial and non-trial patients were combined for further analysis. There was no correlation between outcome and age, blood pressure, serum total protein, or serum albumin. Although rates of proteinuria did not correlate with outcome, all those with progression to ESRD had nephrotic levels of proteinuria at onset. Only five of 28 patients with nephrotic levels of proteinuria and severe onset histopathology recovered fully. No patient with crescents in 50% or more of glomeruli went on to full recovery. Recurrence of non-renal symptoms did not correlate with outcome. Nephrotic syndrome, decreased GFR, and more severe histopathology at onset, as well as persistence of urinary abnormalities for several years, are ominous signs.

Abstract
Henoch-Schönlein purpura (HSP) is an IgA-mediated small vessel vasculitis which commonly involves the skin, gastrointestinal system and kidneys. Numerous HSP triggers have been identified, and pregnancy has been reported as an exacerbating factor. After a pregnant woman had been diagnosed as having new-onset HSP, we reviewed all cases of immunofluorescence-proven HSP evaluated by the Department of Dermatology at the Johns Hopkins Hospital between 1990 and 2002, and report three cases of HSP occurring during pregnancy. Two patients developed new-onset HSP, one at 16 weeks gestation and one at 22 weeks, while the third developed a recurrence of HSP at 12 weeks gestation after 19 years of remission. We conclude that pregnancy may be a trigger for HSP onset or recurrence in susceptible individuals.

Abstract
UNLABELLED Vasculitis can range in severity from a self-limited single-organ disorder to a life-threatening disease with the prospect of multiple-organ failure. This condition presents many challenges to the physician, including classification and diagnosis, appropriate laboratory workup, treatment, and the need for careful follow-up. The physician must not only be able to recognize vasculitis but also be able to provide a specific diagnosis (if possible) as well as recognize and treat any underlying etiologic condition. Most diagnostic criteria are based on the size of vessel involvement, which often correlates with specific dermatologic findings. This may allow the dermatologist to provide an initial diagnosis and direct the medical evaluation. This article reviews the classification and diagnosis of cutaneous vasculitic syndromes and current treatment options; it also presents a comprehensive approach to diagnosing and treating the patient with suspected cutaneous vasculitis. (J Am Acad Dermatol 2003;48:311-40.) LEARNING OBJECTIVE At the completion of this learning activity, participants should be familiar with the classification and clinical features of the various forms of cutaneous vasculitis. They should also have a rational approach to diagnosing and treating a patient with vasculitis.

Abstract
ABSTRACT. IgA nephropathy (IgA-N) that comprises Berger disease and Henoch-Schönlein Purpura (HSP) nephritis is defined by mesangial IgA deposits. Recently, this group has characterized a new receptor for IgA, the transferrin receptor (CD71), expressed on mesangial cells. To assess whether CD71 was involved in the pathogenesis of IgA-N, its expression was analyzed together with IgA deposits on 16 kidney biopsies from 16 patients with Berger disease (n = 4) or HSP (n = 12). These biopsies were compared with 17 kidney biopsies of a group of 15 patients (control group) with other glomerulonephritis, including systemic lupus erythematosus, poststreptococcal acute glomerulonephritis, membranoproliferative glomerulonephritis, steroid-sensitive minimal change nephrotic syndrome, steroid-resistant idiopathic nephrotic syndrome with focal and segmental glomerulosclerosis, and persistent and isolated proteinuria with minimal change on kidney biopsy. In this control group, IgA deposits could be observed in eight kidney biopsies of seven patients. These biopsies were also compared with normal kidney specimens (normal group). In normal kidney, it was found that CD71 was linearly expressed on tubular epithelium but was either not expressed or very dimly in glomeruli. In contrast, CD71 was strongly expressed in 105 of the 107 glomeruli of the kidney biopsies from the IgA-N group. For the control group, it was found that expression of CD71 in glomeruli was correlated to the presence of IgA deposits. Indeed, among the 87 glomeruli of nine kidney biopsies (eight patients) without IgA fixation, 78 exhibited no CD71 expression and nine exhibited a very dim one. On the other hand, all 49 glomeruli of the eight kidney biopsies (seven patients) in which IgA deposits were detected exhibited CD71 expression (P < 10(-4)). Performance of dual-labeling studies with confocal microscopy on kidney biopsies of IgA-N patients demonstrated that most of the IgA deposits co-localized with CD71. It was also demonstrated that the intensity of the expression of CD71 was not linked to the intensity of clinical or biologic findings but to the intensity of cellular proliferation in both IgA-N and control groups. These results show that mesangial CD71 expression is not specific to IgA-N. However, the association between IgA deposits and CD71 expression and their co-localization in the mesangium provide strong evidence that CD71 is a major IgA receptor on mesangial cells.

Abstract
Vasculitis is an important diagnostic consideration in the child with prolonged fever, unexplained pains, new neurologic findings, or other persistent and troubling signs of inflammation. As long as the etiology of vasculitis remains unknown, reliance upon imperfect diagnostic criteria is likely to remain the state of the art. Nonetheless, anti-inflammatory and immunosuppressive therapy is highly effective in speeding resolution of systemic inflammation and reducing long-term complications. The care, experience, and acumen of the treating physician thus remain the gold standard for diagnosing and treating pediatric vasculitides. In all cases this begins with a high level of suspicion in the primary care physician.
