Plasmapheresis therapy in an elderly patient with rapidly progressive Henoch-Schönlein purpura with disseminated organ involvement

Therapeutic plasma apheresis for IgA vasculitis-related gastrointestinal bleeding

INTRODUCTION

Adult-onset IgA vasculitis (IgAV) often presents with severe renal and gastrointestinal (GI) complications, yet therapeutic guidelines for life-threatening manifestations remain unclear.

METHODS

We conducted a systematic text-mining analysis of all PubMed-indexed case reports of IgAV treated with therapeutic plasma exchange (TPE).

RESULTS

We describe an 80-year-old woman with refractory GI bleeding and rapidly progressive glomerulonephritis. Despite high-dose corticosteroids and cyclophosphamide, GI bleeding persisted and necessitated multiple transcatheter embolization. A total of seven sessions of TPE using fresh frozen plasma successfully controlled disease activity, resulting in improvement of GI bleeding. Literature review suggests that TPE may provide additive benefits in IgAV patients, particularly in those unresponsive to standard immunosuppressants.

CONCLUSION

This case supports the utility of TPE as a valuable adjunctive therapy in severe IgAV with organ-threatening manifestations and highlights the need for further studies to define optimal indications.

IgA vasculitis nephritis-outcomes in adult-onset disease

OBJECTIVES

IgA vasculitis (IgAV) in adults has been relatively under-investigated. Since outcomes are worse in other forms of vasculitis with increasing age, we investigated the outcomes of IgAV comparing younger adults (18-34), middle-aged adults (35-64) and elderly patients (≥64 years) focusing on kidney outcomes.

METHODS

We identified patients with renal biopsy-confirmed IgAV nephritis and collected data regarding clinical features and progression to end stage kidney disease (ESKD). The relationship between patient factors and ESKD was analysed by regression.

RESULTS

We identified 202 cases, 34% aged 18-34, 43% aged 35-64 and 23% elderly (>64 years). Median follow-up was 44 months. Elderly patients were more likely to present with ESKD (23.9%) compared with middle-aged (13.7%) and younger adults (2.9%) (χ2 11.6, P = 0.002). In patients with independent kidney function at biopsy, there was no difference in outcomes between age groups. Male gender, Black ethnicity, diabetes, histological evidence of chronic renal damage and estimated glomerular filtration rate < 30 ml/min were risk factors for development of ESKD. In this observational study 68.3% of patients received glucocorticoids and 56.9% additional immunosuppression.

CONCLUSION

Elderly patients with IgAV are more likely to have ESKD at presentation, but there is no difference in renal survival between age groups, among those presenting with independent renal function. Renal impairment at biopsy is an independent risk factor for subsequent development of ESKD. There is significant variability in the timing of kidney biopsy and management of these patients among specialist centres. Young adults have outcomes more in keeping with childhood IgAV.

Efficacy and Safety of Plasma Exchange as an Adjunctive Therapy for Rapidly Progressive IgA Nephropathy and Henoch-Schönlein Purpura Nephritis: A Systematic Review

Patients with IgA nephropathy (IgAN), including Henoch-Schönlein purpura nephritis (HSP), who present with rapidly progressive glomerulonephritis (RPGN) have a poor prognosis despite aggressive immunosuppressive therapy. The utility of plasmapheresis/plasma exchange (PLEX) for IgAN/HSP is not well established. This systematic review aims to assess the efficacy of PLEX for IgAN and HSP patients with RPGN. A literature search was conducted using MEDLINE, EMBASE, and through Cochrane Database from inception through September 2022. Studies that reported outcomes of PLEX in IgAN or HSP patients with RPGN were enrolled. The protocol for this systematic review is registered with PROSPERO (no. CRD42022356411). The researchers systematically reviewed 38 articles (29 case reports and 9 case series articles) with a total of 102 RPGN patients (64 (62.8%) had IgAN and 38 (37.2%) had HSP). The mean age was 25 years and 69% were males. There was no specific PLEX regimen utilized in these studies, but most patients received at least 3 PLEX sessions that were titrated based on the patient's response/kidney recovery. The number of PLEX sessions ranged from 3 to 18, and patients additionally received steroids and immunosuppressive treatment (61.6% of patients received cyclophosphamide). Follow-up time ranged from 1 to 120 months, with the majority being followed for at least 2 months after PLEX. Among IgAN patients treated with PLEX, 42.1% (n = 27/64) achieved remission; 20.3% (n = 13/64) achieved complete remission (CR) and 18.7% (n = 12/64) partial remission (PR). 60.9% (n = 39/64) progressed to end-stage kidney disease (ESKD). Among HSP patients treated with PLEX, 76.3% (n = 29/38) achieved remission; of these, 68.4% (n = 26/38) achieved CR and 7.8% achieved (n = 3/38) PR. 23.6% (n = 9/38) progressed to ESKD. Among kidney transplant patients, 20% (n = 1/5) achieved remission and 80% (n = 4/5) progressed to ESKD. Adjunctive plasmapheresis/plasma exchange with immunosuppressive therapy showed benefits in some HSP patients with RPGN and possible benefits in IgAN patients with RPGN. Future prospective, multi-center, randomized clinical studies are needed to corroborate this systematic review's findings.

Guidelines on the Use of Therapeutic Apheresis in Clinical Practice-Evidence-Based Approach from the Writing Committee of the American Society for Apheresis: The Seventh Special Issue

The American Society for Apheresis (ASFA) Journal of Clinical Apheresis (JCA) Special Issue Writing Committee is charged with reviewing, updating, and categorizing indications for the evidence-based use of therapeutic apheresis in human disease. Since the 2007 JCA Special Issue (Fourth Edition), the Committee has incorporated systematic review and evidence-based approaches in the grading and categorization of apheresis indications. This Seventh Edition of the JCA Special Issue continues to maintain this methodology and rigor to make recommendations on the use of apheresis in a wide variety of diseases/conditions. The JCA Seventh Edition, like its predecessor, has consistently applied the category and grading system definitions in the fact sheets. The general layout and concept of a fact sheet that was used since the fourth edition has largely been maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis in a specific disease entity. The Seventh Edition discusses 87 fact sheets (14 new fact sheets since the Sixth Edition) for therapeutic apheresis diseases and medical conditions, with 179 indications, which are separately graded and categorized within the listed fact sheets. Several diseases that are Category IV which have been described in detail in previous editions and do not have significant new evidence since the last publication are summarized in a separate table. The Seventh Edition of the JCA Special Issue serves as a key resource that guides the utilization of therapeutic apheresis in the treatment of human disease. J. Clin.

Long-Term Therapeutic Plasma Exchange to Prevent End-Stage Kidney Disease in Adult Severe Resistant Henoch-Schonlein Purpura Nephritis

A 27-year-old man presented with a palpable purpuric skin rash and joint and abdominal pain in April 2010. He had acute kidney injury and his creatinine quickly deteriorated to 687 μmol/L, with associated nephrotic range proteinuria. Kidney biopsy showed crescentic Henoch-Schonlein nephritis. He was treated with intravenous cyclophosphamide and prednisolone despite which his renal function deteriorated; he required haemodialysis for a short duration and seven sessions of therapeutic plasma exchange (TPE). Renal function improved, but after discharge from hospital he suffered 2 further relapses, each with AKI, in 4 months. Cyclophosphamide was not effective and therefore Rituximab was introduced. He initially had a partial response but his renal function deteriorated despite continued therapy. TPE was the only treatment that prevented rapid renal functional deterioration. A novel long-term treatment strategy involving regular TPE every one to two weeks was initiated. This helped to slow his progression to end-stage kidney disease over a 3-year period and to prolong the need for renal replacement therapy over this time.

Henoch-Schönlein purpura complicated with severe gastrointestinal bleeding

Bleeding from the gastrointestinal tract is one of the common determinants of morbidity and mortality in the ordinary clinical setting. The gastrointestinal involvement of Henoch-Schönlein purpura (HSP) has often been described as self-limiting, with no long-term morbidity. In this report, we describe our experience with a male HSP patient who presented with abdominal pain, loss of appetite and deteriorated renal function associated with nephrotic syndrome. Despite the use of aggressive immunomodulatory treatments, including corticosteroids and plasmapheresis, he developed lethal gastrointestinal hemorrhage. We believe that the accumulation of more experience with additional cases similar to ours is mandatory for the establishment of optimal management for HSP patients with severe gastrointestinal manifestations.

Therapeutic apheresis for renal disorders

This review summarizes the clinical evidence and practical details for the use of plasmapheresis and other apheresis modalities for each indication in nephrology. Updated information on the molecular biology and immunology of each renal disease is discussed in relation to the rationale for apheresis therapy and its place amid other available treatments. Autoantibody-mediated diseases, such as anti-GBM (anti-glomerular basement membrane) glomerulonephritis (GN), ANCA (antineutrophil cytoplasmic antibody)-related GN and the antibody-mediated type of TTP (thrombotic thrombocytopenic purpura), and alloantibody-mediated diseases such as kidney transplant sensitization and humoral rejection, can be treated by various plasmapheresis methods. These include standard plasmapheresis with a replacement volume, or plasmapheresis with online plasma purification using adsorption columns or secondary filtration. However, it should be noted that the pathogenic molecules implicated in FSGS (focal segmental glomerulosclerosis), myeloma cast nephropathy, and perhaps other diseases are too small to be removed by most online purification methods. A great majority of controlled trials and series on which evidence-based treatment recommendations are made were performed using centrifugal plasmapheresis; it is presumed that membrane-separation plasmapheresis is equally efficacious. For some rarer diseases, such as MPGN (membranoproliferative GN) type 2 with factor H abnormalities or C3Nef (C3 nephritic factor) autoantibodies, there are only a few case reports, but enough scientific understanding to warrant a trial of plasmapheresis in severe cases. Photopheresis, which is effective for cell-mediated rejection in heart and lung transplantation, has not yet found a place in the routine treatment of kidney transplant rejection.

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.

Henoch-Schonlein purpura nephritis: pathophysiology, treatment, and future strategy

Henoch-Schönlein purpura nephritis is a rare kidney disease leading to chronic kidney disease in a non-negligible percentage of patients. Although retrospective studies suggest beneficial effects of some therapies, prospective randomized clinical trials proving treatment efficacy are still lacking. The dilemma of spontaneous recovery even in patients with severe clinical and histologic presentation and of late evolution to chronic kidney disease in patients with mild initial symptoms renders it difficult for clinicians to expose patients to treatment protocols that are not evidence-based. A better understanding of the pathophysiology of progression to chronic kidney disease in Henoch-Schönlein purpura patients could be achieved by designing prospective international multicenter studies looking at determinants of clinical and histopathological evolution as well as possible circulating and urinary markers of progression. Such studies should be supported by a database available on the web and a new histologic classification of kidney lesions. This paper reports clinical, pathologic, and experimental data to be used for this strategy and to assist clinicians and clinical trial designers to reach therapeutic decisions.

Massive lower gastrointestinal haemorrhage, successfully treated with corticosteroids, as main symptom of Schönlein-Henoch purpura

Schönlein-Henoch purpura is a small vessel disease that affects mainly skin and kidney, although several gastrointestinal symptoms may occur including abdominal pain, intussusception, perforation or bleeding. Massive lower gastrointestinal haemorrhage is rare and even more as the main symptom of the disease. We present a case of a 2-year-old boy with Schönlein-Henoch purpura who developed a massive lower gastrointestinal bleeding requiring blood transfusion. In this patient both Schönlein-Henoch purpura and gastrointestinal haemorrhage were successfully treated with intravenous methylprednisolone, avoiding surgical intervention. Physicians need to have a high index of suspicion when evaluating these patients, even more when dermatologic signs are scarce. Glucocorticosteroid therapy may be effective when treating severe gastrointestinal symptoms.

Successful treatment of Henoch-Schonlein purpura nephritis with plasma exchange in an adult male

Henoch-Schonlein purpura (HSP) frequently occurs in children under 15 years of age but is quite rare in adults. Most children who develop HSP nephritis completely recover from the illness, whereas up to 40% of adults have persistent hematuria and 10% develop chronic renal failure. Plasma exchange alone has been shown to be beneficial in children who have HSP nephritis. Adults have been treated using immunosuppressive drugs such as cyclophosphamide but effects are not certain. Here, we present a case of a 59-year-old white male who developed HSP nephritis while undergoing treatment with steroids. The patient developed acute renal failure with proteinuria and hematuria ∼2 weeks after being initially diagnosed with HSP by skin biopsy. Renal biopsy showed proliferative, exudative glomerulonephritis involving all 20 glomeruli; some with early crescent formation. Immunofluorescence staining showed 3+ IgA deposits in mesangium suggesting HSP-induced GN. The patient's serum creatinine rose to 2.5 mg/dl with ∼5 g of proteinuria by dipstick. Steroids were continued and the patient received plasma exchange treatments. Due to a very low leukocyte count, immunosuppressive agents were not given. Subsequently, renal function improved and the creatinine level came down to 1.3 mg/dl and proteinuria to <1 g/24 h. Since then, 1 year after this event, his serum creatinine has continued to stay at 1.2 mg/dl and he has trace proteinuria while taking a low-dose ACE inhibitor. This case illustrates the usefulness of plasma exchange in adult onset HSP nephritis, even without concomitant use of cytotoxic agents.

Gastrointestinal manifestations of Henoch-Schonlein Purpura

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.

Successful treatment of recurrent Henoch-Schönlein purpura in a renal allograft with plasmapheresis

Acute and severe cases of Henoch-Schönlein purpura (HSP) nephritis have been treated with plasmapheresis (PA) in both adults and children. It has been used either alone or with steroids, antiplatelets or cytoxic drugs. Generally, renal function has been shown to improve when PA is utilized. The role of PA in recurrent HSP after renal transplantation is unclear and has not been well described in the literature. We report a 29-year-old female with HSP who developed end-stage renal disease and subsequently underwent a renal transplantation with eventual loss of the allograft 5 years later due to recurrent HSP nephritis. Retransplantion was performed and the patient developed active HSP nephritis in her second allograft within a week after transplantation. In an effort to preserve her allograft, four cycles of PA were performed. Her proteinuria resolved and renal biopsies afterwards demonstrated marked reduction in mesangial IgA deposition. We conclude that PA may be useful in recurrent HSP nephritis, especially when used early. The risk of additional immunosuppression caused by PA needs to be considered. More studies need to be done to evaluate the efficacy of PA in this setting as well as to define the optimal treatment regimen.
