A clinical study of Henoch-Schönlein Purpura associated with malignancy

Exploring the Diagnostic Odyssey of IgA Vasculitis

IgA vasculitis is a form of small vessel vasculitis characterized by IgA immune complex deposition. Although primarily affecting children, it can also occur in adults, often with more severe manifestations and a higher risk of chronic kidney disease (CKD). The authors present the case of a 77-year-old man with significant cardiovascular risk and atrial fibrillation who was admitted to the emergency department (ED) with pruritic and painful palpable purpuric rash, weight loss, and asthenia persisting for approximately one month prior to presentation. Laboratory findings revealed normocytic normochromic anemia, worsening renal function, elevated inflammatory markers, and leukoerythrocyturia. Initially diagnosed as infectious purpura associated with urinary tract infection, the patient was discharged with a prescription for antibiotics (cefixime). Subsequent worsening of the skin lesions, constitutional symptoms, and gross hematuria prompted a second visit to the ED, and the persistent deterioration of kidney function and inflammatory parameters led to admission for further investigation and consideration of a kidney biopsy. This case report describes the etiological investigation, providing a brief review of the typical characteristics of this disease and highlighting the importance of certain factors in establishing the diagnosis, notably the need and timing of a biopsy of the affected organ for a definitive diagnosis. Additionally, the clinical case underscores the diagnostic challenge, particularly when histological confirmation is elusive.

IgA vasculitis as an immune-related adverse event of durvalumab: A case report

A 78-year-old man with lung cancer underwent concurrent chemoradiotherapy followed by durvalumab for 24 cycles. After 6 months, he presented with anorexia and palpable purpura of the lower extremities, with increased proteinuria, hematuria, and elevated creatinine levels. Skin and kidney biopsies suggested a diagnosis of IgA vasculitis. No evidence of cancer progression was found; moreover, no infection or drug could be identified as the cause. Therefore, he was diagnosed with IgA vasculitis as an immune-related adverse event (irAE) caused by durvalumab. Because immune checkpoint inhibitors can cause vasculitis, clinicians should be cautious during their administration and after their discontinuation.

IgA Vasculitis in a Lung Cancer Patient During Chemoradiotherapy

A 72-year-old man with locally advanced lung squamous cell carcinoma experienced red purpura on the lower legs and hematuria when the disease progressed during definitive chemoradiotherapy. He had renal dysfunction and proteinuria. Biopsy specimens of the skin lesion and kidney revealed immunoglobulin A vasculitis. Potential causes such as paraneoplastic syndrome and cancer treatment have been proposed. The administration of steroids rapidly improved the symptoms. The presentation of immunoglobulin A vasculitis is accompanied by malignancies. Clinicians should keep this syndrome in mind, even during curative-intent treatment.

Henoch-Schönlein Purpura Associated With Diffuse Large B-cell Lymphoma of the Orbit

The association between Henoch-Schönlein purpura (HSP) and neoplasia is rare and has been more commonly reported in cases of solid tumors rather than hemotological malignancies. To the authors' knowledge, HSP in association with orbital lymphoma has not been previously reported. An 84-year-old man underwent anterior orbitotomy with biopsy for a rapidly growing orbital mass. Immediately following this procedure, he developed petechial rash, flash pulmonary edema, and kidney dysfunction with hematuria and proteinuria. Orbital biopsy revealed diffuse large B-cell lymphoma while skin and kidney biopsies showed features consistent with HSP. Multidisciplinary team involvement and treatment with chemotherapy and corticosteroid resulted in an excellent clinical response. Clinicians should be aware that HSP and orbital diffuse large B-cell lymphoma can co-occur, potentially leading to life-threatening rapid fluid shifts and metabolic derangements.

Morbidity and mortality in adult-onset IgA vasculitis: a long-term population-based cohort study

OBJECTIVES

With sparse data available, we investigated mortality and risk factors in adults with IgAV.

METHODS

Observational population-based cohort study using state-wide linked longitudinal health data for hospitalised adults with IgAV (n = 267) and matched comparators (n = 1080) between 1980-2015. Charlson comorbidity index (CCI) and serious infections (SI) were recorded over an extensive lookback period prior to diagnosis. Date and causes of death were extracted from WA Death Registry. Mortality rate (deaths/1000 person-years) ratios (MRR) and hazard ratio (HR) for survival were assessed.

RESULTS

During 9.9 (±9.8) years lookback patients with IgAV accrued higher CCI scores (2.60 vs1.50 p < 0.001) and had higher risk of SI (OR 8.4, p < 0.001), not fully explained by CCI scores. During 19 years follow-up, the rate of death in Patients with IgAV (n = 137) was higher than in comparators (n = 397) (MRR 2.06, CI 1.70-2.50, p < 0.01) and the general population (SMRR 5.64, CI 4.25, 7.53, p < 0.001). Survival in IgAV was reduced at five (72.7 vs. 89.7%) and twenty years (45.2% vs. 65.6%) (both p < 0.05). CCI (HR1.88, CI:1.25 - 2.73, p = 0.001), renal failure (HR 1.48, CI: 1.04 - 2.22, p = 0.03) and prior SI (HR 1.48, CI:1.01 - 2.16, p = 0.04) were independent risk factors. Death from infections (5.8 vs 1.8%, p = 0.02) was significantly more frequent in patients with IgAV.

CONCLUSIONS

Premorbid comorbidity accrual appears increased in hospitalized patients with IgAV and predicts premature death. As comorbidity does not fully explain the increased risk of premorbid infections or the increased mortality due to infections in IgAV, prospective studies are needed.

Immunoglobulin A Vasculitis in a Patient on Hemodialysis and With a Metastatic Liver Lesion

We present the case of a 79-year-old man on hemodialysis with immunoglobulin A (IgA) vasculitis. He developed palpable purpura three weeks after having pneumonia. A skin biopsy showed leukocytoclastic vasculitis with IgA and C3 deposition. He received a topical corticosteroid for his IgA vasculitis. He was also diagnosed with a metastatic liver lesion, which was thought to be of colorectal origin because of the elevations in carcinoembryonic antigen and cancer antigen 19-9 levels. The skin biopsy played an important role in the diagnosis of the patient on hemodialysis. Pneumonia and a metastatic liver lesion thought to be from colorectal cancer might be related to the pathogenesis of IgA vasculitis.

Henoch-Schönlein purpura in a patient with oesophageal cancer: A case report

RATIONALE

Understanding the association between Henoch-Schönlein purpura (HSP) and malignancy is essential for early diagnosis and treatment of the potential lethal disease. To the best of our knowledge, there has been only one published case of HSP coexisting with oesophageal cancer. Here, we report another patient diagnosed with HSP and oesophageal squamous carcinoma simultaneously.

PATIENT CONCERNS

A 60-year-old Chinese male was referred to our hospital because of intermittent abdominal pain, abdominal distension, melena, lower extremities purpura. Positive laboratory values included pancytopenia, microscopic hematuria, nephrotic proteinuria, hematochezia, hypoalbuminemia, hyperlipidaemia, hypocomplementemia, and increased levels of hepatobiliary enzymes and immunoglobulin (Ig) A. Gastrocolonoscopy showed multiple erosion lesion on descending duodenum, terminal ileum, and ileal flap. Biopsy of these lesions suggested non-specific inflammation.

DIAGNOSES

HSP (IIIb type) was diagnosed based on renal pathology examination in accordance with the International Study of Kidney Disease in Children (ISKDC) classification. Liver biopsy confirmed the diagnosis of nodular cirrhosis (Ishak 5). Gastroscopy unintentionally revealed three oesophagus lesions. Pathology study suggested intermediate differentiated squamous cell carcinoma (cTNM IB).

INTERVENTIONS

Before admission, he was administered intravenous Ig 10 g once daily(qd) for 10 days, methylprednisolone 40 mg qd for a week, followed by prednisolone 50 mg qd for almost 8 weeks. Endoscopic submucosal dissection (ESD) was performed to remove all lesions with negative margin after prednisolone was tapered (5 mg per week until 10 mg qd).

OUTCOMES

Despite prednisone being tapered to 2.5 mg qd within 2 months, complete remission of HSP and esophageal malignancy was achieved after the resection of the esophagus lesions during 12 months follow-up.

LESSONS

We report a rare case of oesophageal squamous cell carcinoma initially presented as HSP. This case suggests the importance of evaluating adult patients with HSP for an underlying malignancy.

New insights on IgA vasculitis with underlying solid tumor: a nationwide French study of 30 patients

OBJECTIVE

IgA vasculitis (IgAV) frequently occurs during or after a mucosal infection; it also rarely occurs in patients with cancer. We hypothesized that cancer could impact the baseline characteristics and/or outcome of vasculitis. We aimed to describe the presentation of IgAV in patients with cancer (IgAV ca+) compared to patients without cancer.

METHODS

We conducted a nationwide retrospective study of adult patients in France who presented with both IgAV and cancer. Baseline characteristics were described and compared with those of the 260 patients included in a nationwide French IgAV study.

RESULTS

Thirty patients were included. The mean age was 69 ± 12 years; 80% were men. Compared to patients without underlying cancer, IgAV ca+ patients were older (69 ± 12 vs. 50 ± 18 years; p < 0.0001) and they presented more frequently with necrotic purpura (53 vs. 26%; p < 0.002) and intra-alveolar hemorrhage (10 vs. 0.5%; p < 0.0001). IgAV ca+ patients frequently had elevated serum IgA levels (79 vs. 53%; p < 0.034); most (n = 22, 73%) had adenocarcinoma or urothelial carcinoma involving the large intestines (n = 6), bladder (n = 5), and lung (n = 5). Most IgAV ca+ patients had progressive cancer (n = 21); a minority had metastatic disease (n = 2) at IgAV diagnosis. After a median follow-up of 3 months, 8 deaths were observed but none was related to IgAV.

CONCLUSION

Compared to their noncancer counterpart, patients with IgAV related to cancer were older and more frequently presented with necrotizing purpura, intra-alveolar hemorrhage, and elevated serum IgA levels. Adult patients with IgAV and these latter characteristics should be carefully screened for cancer. Key Points • Clinical and biological characteristics of patients presenting with IgAV are distinct depending on the underlying cause of vasculitis related to cancer. • Patients with IgAV related to cancer are older, and compared to their counterparts without IgAV, they present more frequently with necrotic purpura, alveolar hemorrhage, and elevated serum IgA levels. • All adult patients with IgAV should be screened for cancer, and there should be a focus on elderly male patients presenting with necrotic purpura and/or alveolar hemorrhage.

Henoch-Schönlein Purpura Presenting in Association With Neuroblastoma: A Case Report

Henoch-Schönlein purpura (HSP) is a common systemic vasculitis affecting children. It is managed in the outpatient setting and rarely associated with malignancy. We present a case of neuroblastoma in a 7-year-old boy diagnosed after suspected HSP. Our case highlights the importance of maintaining a broad differential diagnosis in children with atypical HSP and performing a skin biopsy with immunofluorescence when a rash is present.

Bevacizumab-induced immunoglobulin A vasculitis with nephritis: A case report

RATIONALE

Bevacizumab-an inhibitor of vascular endothelial growth factor-is effective against various advanced cancers. However, it is associated with the development of hypertension and high-grade proteinuria during thrombotic microangiopathy of the kidney. In addition, there are several reports of immunoglobulin A deposition in the glomeruli, but the etiology is unclear.

PATIENT CONCERNS

A 67-year-old Japanese man with metastatic rectal cancer underwent low anterior rectal resection, followed by treatment with bevacizumab and SOX (S-1 plus oxaliplatin). Six months later, the patient developed hematuria, nephrotic syndrome, and purpura.

DIAGNOSES

Renal biopsy revealed endocapillary proliferative glomerulonephritis. Immunofluorescence analyses showed granular mesangial deposition of galactose-deficient immunoglobulin A1. Skin biopsy revealed leukocytoclastic vasculitis.

INTERVENTIONS

We ceased bevacizumab treatment, while continuing the remaining chemotherapy regimen, as we suspected bevacizumab-induced nephropathy.

OUTCOMES

Proteinuria and purpura improved immediately after cessation of bevacizumab. We identified this as a case of bevacizumab-induced immunoglobulin A vasculitis with nephritis.

LESSONS

To our knowledge, this is the first case of bevacizumab-related immunoglobulin A vasculitis with nephritis, as evidenced by galactose-deficient immunoglobulin A1. When a patient's urine tests are abnormal during bevacizumab treatment, clinicians should consider not only thrombotic microangiopathy but also vasculitis.

Clinical Characteristics of Biopsy-Proven IgA Vasculitis in Children and Adults: A Retrospective Cohort Study

OBJECTIVE

To describe the differences in clinical characteristics and outcome between adult- and childhood-onset biopsy-proven IgA vasculitis (IgAV) in North America.

PATIENTS AND METHODS

Patients with IgAV diagnosed from January 1, 1997, through December 31, 2016, were retrospectively identified. Data were abstracted from direct medical record review. Kaplan-Meier methods were used to estimate survival rates.

RESULTS

A total of 243 patients with IgAV were included (227 [93.4%] white, 141 [58.0%] male); 174 patients were adults (≥21 years), and 69 were younger than 21 years. Compared with patients younger than 21 years, adults at baseline more frequently had ulcerative skin lesions (19 [10.9%] vs 1 [1.4%]; P=.02) and nephrotic-range proteinuria (21 of 96 [21.9%] vs 1 of 38 [2.6%]; P=.007) but less commonly had abdominal pain (59 [33.9%] vs 42 [60.9%]; P<.001), ischemic gastrointestinal tract involvement (18 [10.3%] vs 14 [20.3%]; P=.04), and arthralgias (66 [37.9%] vs 42 [60.8%]; P<.001). During 389 person-years of follow-up, 29 deaths were observed. Five-year survival rates for patients aged younger than 21, 21 to 50, and 51 years or older were 100%, 94%, and 40%, respectively. In comparison to data from the United States life tables for whites, patients 51 years or older at diagnosis had a greater than 7-fold increased risk of mortality (standardized mortality, 7.60 [95% CI, 5.01-11.06]; P<.001).

CONCLUSION

IgA vasculitis in adults is associated with more severe skin/kidney involvement and poorer renal outcome. Among adults with IgAV, patients aged 51 years or older at diagnosis have significantly higher mortality (P<.001).

Clinical and Pathological Characteristics of Elderly Japanese Patients with IgA Vasculitis with Nephritis: A Case Series

Objective This case series aimed to identify the clinical and pathological characteristics of elderly patients (≥60 years) with biopsy-proven IgA vasculitis with nephritis (IgAVN). Methods The clinical and pathological presentation and treatment outcomes were compared between two groups. Patients Patients with IgAVN who were ≥19 years old at the time of their renal biopsy were divided into elderly (≥60 years) and adult (19-59 years) groups. Results Of the 23 patients in our study, 13 were elderly. In the elderly group, the median age at the diagnosis was 68 years (range, 60-85 years), with a median follow-up period of 15 months (range, 3-80 months). Twelve elderly patients had comorbidities, including hypertension, diabetes mellitus, chronic kidney disease, cardiovascular disease, and malignancies. A decrease in the estimated glomerular filtration rate, as well as massive proteinuria and rapidly progressive nephritic syndrome, were more frequent in the elderly group than in the adult group. Furthermore, renal pathological changes, including cellular or fibrocellular crescents, interstitial fibrosis, tubular atrophy, and arteriosclerosis, were more severe among elderly patients than adult patients. All elderly patients were treated with glucocorticoids and had no incidence of end-stage renal disease at the final follow-up; in addition, nine elderly patients had reduced proteinuria with a preserved renal function. Adverse events, including infection, diabetes mellitus, and vascular disorders, were identified in nine patients. Three elderly patients died from severe infections. Conclusion IgAVN in elderly patients is characterized by severe renal involvement. Elderly patients are at higher risk than adults for treatment-related adverse events.

Paraneoplastic IgA Vasculitis in an Adult with Lung Adenocarcinoma

A 50-year-old man with lung adenocarcinoma (c-T1aN2M1b) experienced reddish purpura mainly on the lower legs after receiving 12 cycles of second-line chemotherapy with docetaxel. There was tumor enlargement on computed tomography performed to assess the therapeutic response, so paraneoplastic IgA vasculitis was considered. IgA vasculitis was diagnosed based on a biopsy of the skin lesion and histology of an upper gastrointestinal hemorrhagic mucosal erosion. As IgA vasculitis can lead to serious gastrointestinal or systemic complications, IgA vasculitis should be considered as a differential diagnosis for rashes in patients with malignancy.

Successful rechallenge with ceritinib after leukocytoclastic vasculitis during ceritinib treatment for non-small cell lung cancer harboring the EML4-ALK fusion protein

Anaplastic lymphoma kinase (ALK)-tyrosine kinase inhibitors (TKIs) dramatically improve progression-free survival compared to cytotoxic agents. It is therefore important to manage patients with ALK-TKIs until drug resistance occurs. Leukocytoclastic vasculitis (LCV) is a rare complication during cancer treatment and is associated with a variety of factors. Currently, it is unclear whether we should withdraw a treatment when drug-induced LCV develops.

We report a 40-year-old man with advanced pulmonary adenocarcinoma harboring the EML4-ALK fusion protein who developed LCV during ceritinib treatment. Four weeks after withdrawing ceritinib, we could successfully perform rechallenge with ceritinib at the normal dose. Rapid and massive tumor apoptosis due to ceritinib treatment may lead to neoantigen release and immune complexes deposition.

To the best of our knowledge, we report the first case of LCV in a patient during ALK-TKI treatment. Following this occurrence, we were able to successfully perform rechallenge with ceritinib. Therefore, key drugs used in a patient's treatment regimen should not be discontinued without careful evaluation, and we should also consider the possibility of rechallenge.

Henoch-Schönlein Purpura Complicated by Hepatocellular Carcinoma

Although Henoch-Schönlein purpura (HSP) is known to be accompanied by malignancies, cases with hepatobiliary cancer are extremely rare. A 62-year-old man with palpable purpura rapidly extending to both lower legs was admitted to our hospital. He was undergoing follow-up for cirrhosis caused by chronic hepatitis B virus infection and hepatocellular carcinoma (HCC). He had renal dysfunction with hematuria and proteinuria and abdominal pain. Based on the clinical presentation and skin biopsy findings, he was diagnosed with HSP. The administration of steroids resulted in the rapid improvement of the patient's symptoms and he was discharged 12 days after admission.

Henoch-Schönlein Purpura with Concurrent Cytomegalovirus Duodenitis

Henoch-Schönlein purpura (HSP) is a systemic vasculitis involving the small vessels with distinct clinical features. The etiology of HSP is diverse, and viral infection is one of the many predisposing factors. Cytomegalovirus (CMV) infection mostly affects immune-suppressed patients, but rarely patients with normal immunity can also be affected. Authors experienced a case of HSP patient, with underlying small-cell lung cancer (SCLC) with CMV duodenitis. This is a rare case of HSP diagnosed in SCLC patient with predisposing factor of CMV infection.

Pathogenesis and gastrointestinal manifestations of IgA vasculitis

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

Henoch-Schonlein purpura in mesothelioma

Henoch–Schonlein purpura (HSP) is primarily a childhood immunoglobulin A (IgA)-mediated illness. When adults are affected, malignancy can be associated. We present a rare case of HSP in a 75-year-old man with malignant pleural mesothelioma. He presented with episodes of dizziness and subsequently developed non-palpable purpura across his legs, arthralgia, hematuria, proteinuria, and acute renal impairment. HSP was diagnosed based on clinical and histological findings on biopsy specimens from the skin and kidney that showed a leukocytoclastic vasculitis and mesangioproliferative glomerulonephritis with IgA deposits, respectively. He was treated with high-dose oral steroids with resolution of the skin and renal manifestations of the disease. HSP is rare in adults but has been linked to cancers. This is the first report of HSP in a patient with known malignant pleural mesothelioma.

Incidence of IgA vasculitis in the adult Slovenian population

BACKGROUND

IgA vasculitis (IgAV) is assumed to be uncommon in adults.

OBJECTIVES

To determine the incidence rate of histologically proven IgAV in the adult Slovenian population.

METHODS

A retrospective chart review of adult patients diagnosed with IgAV was performed at the departments of rheumatology, nephrology, infectious diseases and dermatovenereology at an integrated secondary/tertiary university teaching hospital. In order to avoid missing miscoded cases, the Institute of Pathology, University of Ljubljana, Slovenia, provided a list of all patients with an IgAV-compatible histological pattern on biopsy. The annual incidence rate of histologically proven IgAV was calculated.

RESULTS

Eighty-one new cases of IgAV were identified from June 2010 to June 2013. The estimated annual incidence rate of IgAV was 5·1 per 100,000 adults [95% confidence interval (CI) 3·4-7·4]; in men it was 6·1 per 100,000 (95% CI 3·9-10·6) and in women it was 3·7 per 100,000 (95% CI 1·8-6·8).

CONCLUSIONS

Although we only included histologically proven cases of IgAV, the annual incidence rate of 5·1 per 100,000 adults is 3-6-times higher than previously reported.

The first case of Henoch-Schonlein purpura associated with rosuvastatin: colonic involvement coexisting with small intestine

Henoch-Schönlein purpura (HSP) is a systemic vasculitis affecting small vessels. It is the most common systemic vasculitis in children, and is rare in adults. Serious gastrointestinal complications are more common in childhood. Infections and drugs are the most prominent factors in the aetiology. Wall thickening in segments of the small intestine is commonly seen in imaging studies in gastrointestinal system (GIS) involvement. Simultaneous involvement of small intestine and colon is rare. An HSP case involving small intestine and colon in an adult patient due to the use of rosuvastatin, an antihyperlipidaemic agent, is presented, and is first of its kind reported in the literature.

Differences in clinical manifestations and outcomes between adult and child patients with Henoch-Schönlein purpura

We aimed to investigate differences in clinical manifestations and outcomes between adult and child patients with Henoch-Schönlein purpura (HSP), and to analyze the factors associated with poor prognosis for HSP nephritis. This retrospective 10-yr study enrolled 160 patients with HSP who visited Severance Hospital. Purpura was mostly detected in lower extremities, but purpura in upper extremities was more frequently observed in adults than children (41.7% vs 19.3%). Children had a greater frequency of arthralgia (55.4% vs 27.1%), while adults had a greater frequency of diarrhea (20% vs 1.6%). Anemia, elevated C-reactive protein, and level of IgA were more frequently observed in adults (25% vs 7.1%, 65.6% vs 38.4%, 26.3% vs 3.5%). Renal involvement in adults was more severe than in children (79.2% vs 30.4%). Chronic renal failure showed a significant difference in outcomes of HSP between adults (10.4%) and children (1.8%) after a follow up period of an average of 27 months. Furthermore, renal insufficiency at diagnosis was significantly related to the progression to chronic renal failure. Our results showed several differences in the clinical features of HSP between adults and children. Adults with HSP had a higher frequency of renal insufficiency and worse renal outcomes than children. Renal insufficiency at diagnosis might be of predictive value for the progression to chronic renal failure in HSP patients.

Epidemiology of immunoglobulin A vasculitis (Henoch-Schönlein): current state of knowledge

PURPOSE OF REVIEW

To review the current knowledge of epidemiological features of immunoglobulin (Ig) A vasculitis (Henoch-Schönlein) and disease etiology.

RECENT FINDINGS

The annual incidence of IgA vasculitis in the population is an estimated 3-26.7/100 000 for children and infants and 0.8-1.8/100 000 for adults. These may be conservative approximations of the true frequency because of skewed case-finding strategies. In children, the marked autumn-winter peak in incidence rates, the frequent occurrence after an upper respiratory tract infection and the short interval between disease onset in index cases and in other family members collectively point to a transmissible infectious process. A subset of adult IgA vasculitis could be related to preceding or concurrent malignancies. Despite several lines of evidence supporting the critical role of an exogenous factor in IgA vasculitis, recent progress has been made in understanding the genetic susceptibility to IgA vasculitis. Recent findings also lessened the suggestion that IgA vasculitis might be triggered by vaccination.

SUMMARY

IgA vasculitis is two to 33 times more common in children than adults and appears to have a strong environmental component, with possibly different risk factors in childhood and adulthood. Support is strengthening for a role of genetics in IgA vasculitis.

[Skin manifestations of different forms of vasculitis]

The skin not only represents the organ which often reveals the first signs of systemic vasculitis, but also the organ which is most frequently involved in vasculitis. These diseases encompass systemic vasculitides and those which appear to involve the skin only. Among those vasculitides restricted to the skin, some are yet typically associated with other systemic diseases, such as nodular vasculitis, which often occurs during infections by M. tuberculosis, or erythema elevatum diutinum in patients with gammopathy. The type and localization of skin lesions give valuable indications as to the type of vasculitis. Subcutaneous nodules which ulcerate and are surrounded by livedo racemosa are suggestive of polyarteritis nodosa, a palpable purpura with predilection for the lower legs is almost pathognomonic for immune complex vasculitis (e.g. IgA vasculitis or cutaneous leukocytoclastic vasculitis), hemorrhagic papules and necrotic plaques which occur in acral areas after cooling indicate cryoglobulinemic vasculitis, hemorrhagic papules and macules which develop in patients who start to feel worse and develop fever should arouse suspicion of septic vasulitis, while the simultaneous presence of ulcerating nodules and hemorrhagic papules without predilection for the lower legs will suggest ANCA-associated vasculitis. The different morphology of the cutaneous signs of the various vasculitides depends to a large extent on the size of the vessels primarily involved. In this review the cutaneous signs of vasculitides will be presented with reference to the revised nomenclature of the Chapel Hill Consensus Conference from 2012.

Adult Henoch-Schönlein purpura associated with small cell lung cancer: A case report and review of the literature

The present study reports the case of a 53-year-old male who had been suffering from coughing and the presence of a blood-streaked sputum for >1 month. Chest computed tomography (CT) and a bronchoscopic brush smear were performed. The patient was subsequently diagnosed with small cell lung cancer (limited stage). The patient developed polyarthritis, abdominal pain, diarrhea and a purpuric rash at 14 days post thoracotomy surgery for lung cancer. Henoch-Schönlein purpura (HSP) was diagnosed based on the clinical symptoms. The patient received chemotherapy with steroid therapy, which resulted in complete remission of the HSP.

Henoch-schönlein purpura and elevated hepatitis C virus antibody in a girl with nasopharyngeal diffuse large B-cell lymphoma

Henoch-Schönlein purpura (HSP) or hepatitis C virus (HCV) infection was reported in association with malignancies. However, HSP and HCV infection rarely present in pediatric patients with non-Hodgkin's lymphoma. We describe an 8-year-old girl with Stage-IV diffuse large B-cell lymphoma who presented with HSP and elevated HCV antibody titer at diagnosis and at relapse. After treatment, purpura disappeared and HCV antibody titer returned to normal range. There was no recurrence of HSP or elevated HCV antibody during a follow-up of 2 years.

Gastrointestinal involvement revealing Henoch Schonlein purpura in adults: Report of three cases and review of the literature

The diagnosis of Henoch-Schönlein purpura (HSP) is difficult, especially when abdominal symptoms precede cutaneous lesions.

We report three cases of adult HSP revealed by gastrointestinal (GI) involvement.

Henoch Schönlein purpura associated with pulmonary adenocarcinoma

Introduction

Henoch-Schönlein purpura is a common immunoglobulin A-mediated vasculitis syndrome in children. Henoch-Schönlein purpura can also affect adults and is probably related to malignancy.

Case presentation

We report the case of a 61-year-old Japanese man who presented for examination after an abnormal shadow was detected by chest radiography. He received a diagnosis of pulmonary adenocarcinoma, stage IV. Purpura on the legs, abdominal pain, diarrhea, hematuria and proteinuria developed at this time. Henoch-Schönlein purpura was diagnosed, base on the clinical symptoms and histological findings of biopsy specimens of the skin, which showed vasculitis with immunoglobulin A deposits. Our patient received chemotherapy with gemcitabine after successful steroid therapy for the Henoch-Schönlein purpura.

Conclusion

Although hematological malignancies are well-known causes of vasculitides, cases of Henoch-Schönlein purpura associated with lung adenocarcinoma are rare. Our patient was treated with corticosteroid therapy, which cleared the purpura and cytotoxic chemotherapy for the non-small cell lung cancer. However, he died from heart failure due to cardiac tamponade.

The clinical implications of adult-onset henoch-schonelin purpura

Henoch-Schonlein Purpura (HSP) is a small vessel vasculitis mediated by IgA-immune complex deposition. It is characterized by the clinical tetrad of non-thrombocytopenic palpable purpura, abdominal pain, arthritis and renal involvement. Pathologically, it can be considered a form of immune complex-mediated leukocytoclastic vasculitis (LCV) involving the skin and other organs. Though it primarily affects children (over 90% of cases), the occurrence in adults has been rarely reported. Management often involves the use of immunomodulatory or immune-suppressive regimens.
