Abstract
Objectives: Henoch Schönlein Purpura is the most common systemic vasculitis of the childhood. The objective of this study was to evaluate whether there is a clinical significance of laboratory parameters and clinical features on the prediction of the recurrent Henoch Schönlein Purpura in children.Methods: For recurrent Henoch Schönlein Purpura, several laboratory results and clinical features were examined to identify the predictor factors via the logistic regression model in 99 children with Henoch Schönlein Purpura. A p-value of <.05 was considered significant. The patients were divided into two groups as the first attack and the recurrent.Results: The demographic features and laboratory results were not found statistically significant between the two groups (p > .05). The multiple logistic regression model showed that the risk of recurrent Henoch Schönlein Purpura increased 17.2-fold in children with Henoch Schönlein Purpura affected by the four systems including skin, joint, kidney and gastrointestinal system [Odds Ratio (OR) 17.2, 95% CI 1.4-12; p < .001].Conclusion: In our inpatient population, the laboratory characteristics were detected not to be a factor for the prediction of recurrence. However, the four systems including skin, joint, kidney and gastrointestinal involvement may be used as a predictive factor for recurrent HSP.

Abstract
To further investigate into the relapses of Henoch-Schönlein purpura (HSP), we analyzed the frequency, clinical features, and predictors of relapses in series of 417 unselected patients from a single center. After a median follow-up of 12 (interquartile range [IQR]: 2-38) years, almost one-third of the 417 patients (n = 133; 32%; 85 men/48 women) had experienced at least 1 relapse. At the time of disease diagnosis, patients who later experienced relapses had less commonly infections than those who never suffered flares (30.8% vs 41.9%; P = 0.03). In contrast, patients who experienced relapses had a longer duration of the first episode of palpable purpura than those without relapses (palpable purpura lasting >7 days; 80.0% vs 68.1%; P = 0.04). Abdominal pain (72.3% vs 62.3%; P = 0.03) and joint manifestations (27.8% vs 15.5%; P = 0.005) were also more common in patients who later developed relapses. In contrast, patients who never suffered relapses had a slightly higher frequency of fever at the time of disease diagnosis (9.3% vs 3.8%; P = 0.06). At the time of disease diagnosis, corticosteroids were more frequently given to patients who later had relapses of the disease (44% vs 32% in nonrelapsing patients; P = 0.03). Relapses generally occurred soon after the first episode of vasculitis. The median time from the diagnosis of HSP to the first relapse was 1 (IQR: 1-2) month. The median number of relapses was 1 (IQR 1-3). The main clinical features at the time of the relapse were cutaneous (88.7%), gastrointestinal (27.1%), renal (24.8%), and joint (16.5%) manifestations. After a mean ± standard deviation follow-up of 18.9 ± 9.8 years, complete recovery was observed in 110 (82.7%) of the 133 patients who had relapses. Renal sequelae (persistent renal involvement) was found in 11 (8.3%) of the patients with relapses. The best predictive factors for relapse were joint and gastrointestinal manifestations at HSP diagnosis (odds ratio [OR]: 2.22; 95% confidence interval [CI]: 1.34-3.69, and OR: 1.60; 95% CI: 1.01-2.53, respectively). In contrast, a history of previous infection was a protective factor for relapses (OR: 0.60; 95% CI: 0.38-0.94). In conclusion, joint and gastrointestinal manifestations at the time of diagnosis of HSP are predictors of relapses.

Abstract
INTRODUCTION A study was conducted to determine whether the human leukocyte antigen (HLA) B alleles are implicated in the susceptibility to Henoch-Schönlein purpura (HSP) in the largest series of Caucasian HSP patients ever assessed for genetic studies. METHODS The study population was composed of 349 Spanish patients diagnosed with HSP fulfilling the American College of Rheumatology and the Michel et al. classification criteria, and 335 sex and ethnically matched controls. HLA-B phenotypes were determined by sequencing-based typing (SBT) and analyzed by chi-square or Fisher exact test. RESULTS A statistically significant increase of HLA-B*41:02 allele in HSP patients when compared with controls was found (8.3% versus 1.5% respectively; P = 0.0001; OR (odds ratio) =5.76 [2.15-19.3]). These results remained statistically significant after adjusting for Bonferroni correction (P = 0.0028). An internal validation also confirmed the susceptibility effect on HSP associated with HLA-B*41:02 (OR = 5.70 [1.98-16.44]). Since a former study described an association between HLA-DRB1*01:03 and HSP susceptibility, we also evaluated the implication of HLA-B*41:02 independently of HLA-DRB1*01:03. Interestingly, the association remained statistically significant (P = 0.0004, OR = 4.97 [1.8-16.9]). No HLA-B association with specific HSP clinical features was found. CONCLUSIONS Our study indicates that HLA-B*41:02 is associated with the susceptibility to HSP in Spanish patients irrespective of HLA-DRB1 status.

Abstract
Henoch Schonlein purpura (HSP) is the most common vasculitis of childhood. Susceptibility to HSP and associated clinical heterogeneity in HSP may be conferred by a number of genetic loci, including the major histocompatibility complex. We aimed to investigate the implications of the human leukocyte antigen (HLA) class 1 alleles in susceptibility to HSP and determine the possible associations with renal, gastrointestinal (GI), and joint manifestations of the disease. 110 children with HSP (66 boys, 44 girls) and 250 unrelated healthy controls were enrolled in the study. The mean age was 8.65 +/- 3.59 years. HSP was diagnosed on the basis of clinical and laboratory data according to the American College of Rheumatology classification. The diagnosis was supported with skin and/or kidney in most of the patients. Clinical and laboratory findings revealed: skin involvement in 110 (100%), joint manifestations in 82 (74.5%), GI symptoms in 58 (52.7%), and hematuria and/or proteinuria in 36 (32.7%) patients. HLA class 1 alleles were identified by DNA amplification, hybridized with specific primer sequences. Comparison of frequencies between patients and controls were made by using the Fisher's exact test. Odds ratio (OR) was used as the measure of association. HLA A2, A11, and B35 antigens showed an increased risk for predisposition to HSP (OR = 1.714, 95%CI = 1.088-2.700, p = 0.020; OR = 2.185, 95%CI = 1.289-3.703, p = 0.003; and OR = 2.292, 95%CI = 1.451-3.619, p = 0.000, respectively), while HLA A1, B49, and B50 antigens revealed decreased risk for predisposition to HSP (OR = 4.739, 95%CI = 1.828-12.345, p = 0.001; OR = 3.268, 95%CI = 0.955-11.236, p = 0.047; and OR = 7.462, 95%CI = 0.975-55.555, p = 0.024, respectively). Considering the renal involvement and severity of proteinuria, there was no association with HLA class 1 alleles. Our results suggest that the increased frequency of HLA A2, A11, and B35 alleles in unselected pediatric HSP patient population and miscarrying of HLA A1, B49, and B50 could be considered as a risk factor for susceptibility to HSP.

Abstract
BACKGROUND Henoch-Schönlein purpura (HSP), also known as anaphylactoid purpura is a clinically recognizable systemic disorder occurring in children, mainly from ages 3 to 10 years. OBJECTIVES To describe the clinical, epidemiological, and laboratory findings in a group of patients with recurrent HSP, admitted to a tertiary pediatric center. METHODS Retrospective analysis of medical records of patients hospitalized due to HSP between 1969 and 2004. RESULTS Two hundred sixty children (56.7% males) were hospitalized due to HSP, 7 (2.7%) more than once. There were no statistically significant differences in demographic or clinical characteristics between the patients with 1 event of HSP and patients with recurrence. Mean age of the subgroup with recurrence was 3.67 years (10 months to 7.4 years) at the first episode, and 5.03 years (2.2-10 years) at the second one, with a mean lag period of 13.5 +/- 2.8 months (range 2-26). The duration of the recurrent clinical symptoms ranged from 9 to 30 days, and in 72% of those patients, resolution took more than 14 days. CONCLUSION In our inpatient population, no clinical or laboratory characteristics were found to be predictive of recurrence; the second episode was longer than the first and the lag period between the 2 episodes was substantially longer than previously reported. Hospital admissions for recurrent HSP are not common. Nevertheless, a good prognosis was the rule of our admitted patients.

Abstract
BACKGROUND Parvovirus B19 has recently been implicated in various vasculitic syndromes including Henoch Schönlein purpura (HSP), Wegener's granulomatosis and microscopic polyarteritis. The association was established through serology, the identification of DNA in the peripheral blood and affected tissues and more recently by RNA localization to cutaneous capillary endothelium. However, direct localization of the viral DNA to the glomerular and cutaneous endothelium in HSP in correlation with the histopathologic findings has not been demonstrated. METHODS Skin and kidney biopsy tissues were processed for hematoxylin and eosin, immunofluorescent, polymerase chain reaction (PCR) and reverse transcriptase in situ PCR studies. CASE PRESENTATION A 64-year-old-female presented with palpable purpura and nephrotic range proteinuria. Kidney and skin biopsies showed IgA-associated mesangioproliferative glomerulonephritis and IgA-associated leukocytoclastic vasculitis, respectively. A diagnosis of HSP was rendered. Her clinical course was refractory to prednisone. Parvovirus B19 DNA and tumor necrosis factor alpha DNA were identified in the dermal and glomerular capillary endothelial cells and surrounding dermal inflammatory cells. CONCLUSION This is the first documentation of B19 localization to dermal and glomerular capillary endothelium in HSP. It is important to recognize parvovirus B19-associated adult HSP cases, as the treatment of choice is intravenous gamma globulin in concert with anti-TNFalpha therapy. In contrast immunosuppressive therapy may lead to a persistent and/or worsening disease course.

Abstract
Schönlein-Henoch syndrome is a form of systemic small-vessel vasculitis, characterised by vascular and/or mesangial immunoglobulin A1 deposits. The main clinical manifestations are vascular purpura, predominating on the lower limbs, and articular, gastrointestinal and renal symptoms. Pulmonary, cardiac, genital and neurological symptoms have also be observed. The syndrome usually affects children, whereas it is rare in adults. The frequency of renal involvement varies between individual studies (from 20 to 100%). Renal manifestations are usually mild and transient, although chronic nephropathies may occur. Overall, an estimated 2% of children with Schönlein-Henoch purpura progress to renal failure and up to 20% of children with nephritis treated in specialised centres require haemodialysis. The renal prognosis appears to be worse in adults. Aetiological investigations are required, as a triggering factor is found in approximately half the patients (e.g. viral, bacterial and parasitic infections, drugs, toxins, systemic diseases and cancer). Dapsone has beneficial effects on cutaneous, gastrointestinal and articular manifestations in adults, especially those with chronic forms. Corticosteroids may be useful for refractory abdominal pain. Methylprednisolone pulse therapy, immunosuppressive drugs (e.g. cyclophosphamide and azathioprine), plasma exchange and polyclonal immunoglobulin therapy are beneficial in very rare life-threatening forms of the disease and in rare instances where renal function is compromised.

Abstract
Henoch-Schönlein purpura (HSP) is an acute leukocytoclastic vasculitis that primarily affects children. In the current report, the author presents the clinical features of 100 children with HSP and reviews the literature, placing particular emphasis on new information concerning the etiology, immunopathogenesis, and treatment of HSP. The dominant clinical features of HSP are cutaneous purpura (100%), arthritis (82%), abdominal pain (63%), gastrointestinal bleeding (33%), and nephritis (40%). The etiology of HSP remains unknown, but it is clear that IgA plays a critical role in the immunopathogenesis of HSP, as evidenced by increased serum IgA concentrations, IgA-containing circulating immune complexes, and IgA deposition in vessel walls and renal mesangium. There are 2 subclasses of IgA, but HSP is associated with abnormalities involving IgA1 exclusively, and not IgA2. This finding may be a consequence of abnormal glycosylation of O-linked oligosaccharides unique to the hinge region of IgA1 molecules. Although several lines of evidence suggest a genetic susceptibility to HSP, the fundamental basis for the abnormalities involving IgA remain unclear. In general, HSP is an acute, self-limited illness, but one-third of patients will have 1 or more recurrences of symptoms. Corticosteroid therapy may hasten the resolution of arthritis and abdominal pain, but does not prevent recurrences. To date, no form of therapy has been shown to shorten appreciably the duration of HSP. The long-term prognosis of HSP is directly dependent on the severity of renal involvement. Corticosteroids in usual doses have no effect on established nephritis. Evidence is emerging that treatment with high-dose intravenous pulse methylprednisolone coupled with azathioprine or cyclophosphamide may be beneficial in patients with severe nephritis.

Abstract
A 7-year-old boy was seen for severe abdominal pain, vomiting, and a 2.0-kg weight loss of 2 weeks duration. Stools were Hemoccult positive. Upper gastrointestinal (UGI) endoscopy showed multiple, raised red lesions in the duodenal bulb and descending duodenum. Although the patient did not have the typical cutaneous eruption, other findings such as acute onset of abdominal pain in a previously healthy boy, absence of infectious or surgical lesions, and more importantly endoscopic changes seen typically in the descending duodenum, led to the likely diagnosis of Henoch-Schönlein purpura (HSP). The patient was treated with prednisone and the duodenal lesions resolved. The diagnosis of HSP was confirmed 24 weeks after the initial symptom when he developed a palpable purpuric rash over both legs. Thirteen months following the initial symptoms and 6 months after the onset of rash, severe abdominal pain with epigastric tenderness recurred and stools were Hemoccult positive. UGI endoscopy showed multiple, raised red lesions in the descending duodenum as seen earlier. The patient was diagnosed with recurrent HSP. This presentation is atypical because of the abnormally long interval between the onset of abdominal pain and the appearance of the skin rash, and unique because of the endoscopically demonstrated recurrent gastrointestinal lesions.

Abstract
Immunoglobulin (Ig) A-associated vasculitis is commonly equated with the multiorgan systemic vasculitic syndrome Henoch-Schonlein purpura (HSP), which occurs predominantly in the pediatric age group. By natural language search of the databases of two outpatient dermatopathology practices, the authors selected for review 37 cases of IgA-associated vasculitis, 23 of which were associated with antecedent infection, most commonly of the upper respiratory tract. Criteria for a diagnosis of HSP were met in 15 cases, 13 of which were in the setting of prior infection. Lower extremity skin involvement was ubiquitous. A more widespread form of vasculitis was also seen, particularly in the setting of previous infection. Several of the patients with previous infection had underlying medical illnesses including rheumatoid arthritis, atopy, renal failure, lupus erythematosus, insulin dependent diabetes mellitus, autoimmune thyroid disease, and Wegener's granulomatosis. In those patients lacking an apparent microbial trigger, Sjogren's disease with anti-Ro antibodies and hypergammaglobulinemia, lupus erythematosus, inflammatory bowel disease, IgA paraproteinemia, bronchogenic and prostatic carcinoma, cryoglobulinemia, and lymphoma were uncovered. Regardless of whether an infectious stimulus was implicated, certain cofactors with the potential to enhance vascular injury were uncovered; these included anti-Ro antibodies, antineutrophil cytoplasmic antibody, diabetic microangiopathy, and a hyperviscosity state. In the infective group, a pustular vasculitis, defined as a neutrophilic vascular reaction in concert with epithelial pustulation, was seen in 81% of cases versus 33% in the noninfectious group (p = 0.02). The prototypic histomorphology in the noninfective group was one of a mild cell poor leukocytoclastic vasculitis; Vasculitis was of greater severity in patients with antecedent infection (p = 0.026). An infectious trigger, typically of mucosal origin, can frequently be identified in patients with cutaneous IgA-associated vasculitis, especially those with the symptom complex of HSP. The light microscopy appears to distinguish patients who have an infectious trigger from those who do not. IgA-associated vasculitis may be a clue to the presence of certain underlying disorders where there is immune dysregulation or enhanced susceptibility to immune complex entrapment.
