Abstract
INTRODUCTION AND OBJECTIVE Intravenous immunoglobulin (IVIg) is an anti-inflammatory drug with an unclear role in the treatment of patients with lupus nephritis (LN). This systematic review evaluates the evidence for IVIg in the care of patients with LN. METHODOLOGY A systematic search was done in the PubMed, EMBASE, BVS and OVID databases - All EBM Reviews following the PRISMA methodology (registration in PROSPERO CRD42021236662). The variables were extracted: indications for use, dosage, partial or complete response, adverse reactions, initiation of renal replacement therapy, reduction of proteinuria, and mortality. The quality assessment was done with the "The Joanna Briggs Institute (JBI) Critical Appraisal tools for use in Systematic Reviews Checklist". In addition, synthesis reports were prepared through the Synthesis Without Meta-analysis - SWiM guide. RESULTS A total of 2328 articles were obtained (28 were considered for inclusion). When the studies were evaluated, IVIg therapy was found to be between 60% to 70% effective (except for patients with class V LN) with overall responses (complete + partial) even for patients who are refractory to first line treatment. Normalization (<0.5 g) of nephrotic proteinuria occurred in 24% of cases with infrequent adverse events and a mortality plus dialysis composite of 11.5% and 24.1% (most representative study). CONCLUSION In patients with LN refractory to conventional treatment or co-infection situations, the reported data seem to demonstrate effectiveness of IVIg therapy. There are few adverse reactions and caution is exercised when using it on patients with class V NL. However, given the lack of controlled studies with long-term follow-up, these data should be interpreted cautiously thus encouraging the development of high-quality RCTs.

ANCA-Associated Necrotizing Glomerulonephritis Overlapping with Mesangial Proliferative Lupus Nephritis Refractory to Plasmapheresis, Steroid Pulse Therapy, and a Combination of Mycophenolate Mofetil and Rituximab. Case Rep Rheumatol 2018; 2018:3076806. [PMID: 30581646 PMCID: PMC6276453 DOI: 10.1155/2018/3076806] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Accepted: 11/05/2018] [Indexed: 12/11/2022] Open
Abstract
Necrotizing glomerulonephritis (GN) associated with antineutrophil cytoplasmic antibody (ANCA) has been increasingly recognized in the context of class III or IV lupus nephritis (LN), hereafter designated as ANCA-associated necrotizing LN. While this subset of GN appears to portend an unfavorable renal outcome, it is not clear whether it represents a distinct entity and benefits from a more aggressive therapy. We report a 78-year-old woman who presented with rapidly progressive GN and was found to have a double-stranded DNA (dsDNA) antibody, hypocomplementemia, antiphospholipid antibody, and strongly positive myeloperoxidase antibody. Renal pathology showed necrotizing and crescentic GN on a background of mesangial proliferative GN. Her kidney disease did not improve despite the treatment with plasmapheresis, three doses of methylprednisolone pulse therapy followed by prednisone at 1 mg/kg/day, rituximab, and mycophenolate mofetil. This case not only reinforces the notion that ANCA-associated necrotizing LN is associated with high dsDNA antibody, hypocomplementemia, and worse renal outcome but also adds new insight into the full spectrum of this emerging disease entity by demonstrating that the concurrence of ANCA-associated vasculitis is not specific for class III or IV LN but can also be seen on a background of class II LN.

Abstract
OBJECTIVE To assess the clinical features, pathological presentations, treatments and outcomes of lupus nephritis (LN) with anti-neutrophil cytoplasmic antibody (ANCA) positivity. DESIGN A case-control study. METHODS Patients (n=49) were retrospectively included from Jinling Hospital in China if presenting with biopsy-proven ANCA-positive LN between 1985 and 2008. Clinicopathological characteristics and outcomes were analysed and compared with those of a control group (n=1279). We further compared treatment responses and outcomes of ANCA-positive LN patients based on the treatment issued. RESULTS The study included 40 women and 9 men (median age 33 years at biopsy): 38 with myeloperoxidase (MPO)-ANCA, 7 with proteinase 3 (PR3)-ANCA and 4 with double positivity. ANCA-positive LN patients exhibited higher haematuria, serum creatinine levels and systemic lupus erythematosus disease activity index scores. On pathological evaluation, class IV LN was predominant, accounting for 61.22% of cases. Light microscopy revealed significantly higher activity index and chronicity index scores, including cellular crescents, interstitial inflammation, tubular atrophy and interstitial fibrosis. ANCA-positive LN patients receiving mycophenolate mofetil as induction therapy had a higher remission rate and better renal outcomes than those receiving cyclophosphamide. During follow-up, end-stage renal disease developed in seven (14.29%) ANCA-positive LN patients, all of them were MPO-ANCA positive. CONCLUSIONS The characteristics of ANCA-positive LN were massive haematuria and advanced renal insufficiency. We observed a higher remission rate and better prognoses when using mycophenolate mofetil than when using cyclophosphamide as induction therapy.

Positive antineutrophil cytoplasmic antibody serology in patients with lupus nephritis is associated with distinct histopathologic features on renal biopsy. Kidney Int 2017; 92:1223-1231.

Abstract
Class IV-S lupus nephritis is often associated with more necrosis and fewer subendothelial immune deposits compared to class IV-G lupus nephritis, suggestive of necrotising glomerular inflammation found in antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis. ANCAs are present in a significant proportion of patients with lupus nephritis. Here we determine whether ANCAs are associated with distinct clinical and histopathologic features of lupus nephritis. Thirty-two ANCA-positive biopsies were compared to 222 ANCA-negative biopsies from patients with lupus nephritis. The majority (82%) of ANCA-positive patients had antimyeloperoxidase antibodies. Class IV-S lupus nephritis and glomerular necrosis were significantly more common (36% vs. 16% and 35% vs. 15%, respectively) and isolated Class V lupus nephritis significantly less common (10% vs. 29%) in the ANCA-positive group. ANCA-positive patients had significantly higher dsDNA titers (335u/ml vs. 52u/ml), significantly lower serum C4 concentrations (0.125g/L vs. 0.15g/L) and significantly higher serum creatinine (130μmol/L vs. 84μmol/L) at the time of biopsy. Hence ANCAs appear to influence the histological pattern of lupus nephritis and are associated with worse baseline renal function and more active lupus serology. There was no significant difference in outcome between groups when matched for severity of disease and treatment using propensity scoring. Thus, further studies are needed to examine whether ANCAs in patients with lupus nephritis have a pathogenic role and whether they are associated with worse renal outcomes or are simply a marker of more severe disease.

Abstract
We report one case of pregnancy-onset severe diffuse proliferative nephritis in a patient with systemic lupus erythematosus (SLE), who was successfully treated with a combination of anti-tumour necrosis factor (TNF)-alpha, plasmapheresis and high-dose intravenous gammaglobulin. No flares were observed either in clinical symptoms or in laboratory examinations during pregnancy or after delivery. Her autoantibodies except fluorescent anti-nuclear antibodies were negative. We suggest that a combination of anti-TNF-alpha, plasmapheresis and high-dose intravenous gammaglobulin may be a safe and effective therapy for pregnant patients suffering severe lupus nephritis.

Abstract
The aim of the study was to report the clinical, biological, and pathological characteristics of patients with glomerulonephritis (GN) secondary to systemic lupus erythematosus (SLE)/antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) overlap syndrome.A nationwide survey was conducted to identify cases of SLE/AAV overlap syndrome. Data were collected from SLE and AAV French research groups. Inclusion criteria were diagnosis of both SLE and AAV according to international classification criteria and biopsy-proven GN between 1995 and 2014. Additional cases were identified through a systematic literature review. A cohort of consecutive biopsy-proven GN was used to study the prevalence of overlapping antibodies and/or overlap syndrome.The national survey identified 8 cases of SLE/AAV overlap syndrome. All patients were female; median age was 40 years. AAV occurred before SLE (n = 3), after (n = 3), or concomitantly (n = 2). Six patients had rapidly progressive GN and 3/8 had alveolar hemorrhage. All patients had antinuclear antibodies (ANA); 7/8 had p-ANCA antimyeloperoxidase (MPO) antibodies. Renal biopsies showed lupus nephritis (LN) or pauci-immune GN. Remission was obtained in 4/8 patients. A literature review identified 31 additional cases with a similarly severe presentation. In the GN cohort, ANCA positivity was found in 30% of LN, ANA positivity in 52% of pauci-immune GN, with no correlation with pathological findings. The estimated prevalence for SLE/AAV overlap syndrome was 2/101 (2%).In patients with GN, SLE/AAV overlap syndrome may occur but with a low prevalence. Most patients have an aggressive renal presentation, with usually both ANA and anti-MPO antibodies. Further studies are needed to assess shared pathogenesis and therapeutic options.

Abstract
A 43-year-old woman, with a 3-month history of fatigue, anaemia and swollen lymph nodes, underwent biopsy of a lymph node, which revealed reactive lymphadenopathy. Due to an increased serum creatinine concentration and severe proteinuria, a kidney biopsy was performed, which revealed diffuse, segmental, proliferative, immune-complex glomerulonephritis with crescents. Electron microscopy showed tubulo-reticular structures within one endothelial cell. These were a typical clinical presentation and compatible histopathological findings for systemic lupus erythematosus; however, the anti-myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) level was extraordinarily high. In spite of treatment with intravenous cyclophosphamide and methylprednisolone pulse therapy, the patient's kidney function declined. Starting plasma exchange improved her renal function and removed MPO-ANCAs, which were suspected to play the major role in the pathogenesis of glomerulonephritis. These findings indicate that in addition to lupus nephritis, MPO-ANCAs may be involved in the pathogenesis of glomerulonephritis and that the coincidence of systemic lupus erythematosus and ANCA may be responsible for the severe clinical course in our patient.

Abstract
Several cases with an overlap of antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (GN) and lupus nephritis (LN) features have been reported in recent years. However, the clinical and the pathologic features of this condition, including mode of development, histology, and response to treatment, are not fully understood. We report a 77-year-old woman who was diagnosed with Sjögren syndrome 15 years previously. The patient presented with acute worsening of renal function and was diagnosed with new-onset systemic lupus erythematosus. A renal biopsy specimen revealed proliferative LN with synchronous cellular crescents. She was also seropositive for myeloperoxidase-ANCA. Together with the positive staining for immunoglobulins and complement factors on immunofluorescence microscopy and scant subendothelial deposits by electron microscopy, we reached a diagnosis of ANCA-associated crescentic GN overlapping with LN. Although immunosuppressive treatment with methylprednisolone pulse therapy and intravenous cyclophosphamide followed by oral predonisolone was initiated, along with intermittent hemodialysis, these treatments did not induce remission of her GN. Therefore, she continued regular intermittent hemodialysis. However, she died because of candida pneumonia 4 months after admission. Generally, the glomeruli of patients with ANCA-associated GN exhibit different stages of crescents, namely cellular, fibrocellular, or fibrous. The histologically synchronous crescents in this case indicate that ANCA-associated GN overlapping with LN can progress more rapidly than that without LN. This overlapping type of GN may be resistant to conventional immunosuppressive therapies.

Abstract
The occurrence of nephritis in patients with systemic lupus erythematosus is associated with increased morbidity and mortality. The pathogenesis of lupus nephritis is complex, involving innate and adaptive cellular and humoral immune responses. Autoantibodies in particular have been shown to be critical in the initiation and progression of renal injury, via interactions with both Fc-receptors and complement. One approach in the management of patients with lupus nephritis has been the use of intravenous immunoglobulin. This therapy has shown benefit in the setting of many forms of autoantibody-mediated injury; however, the mechanisms of efficacy are not fully understood. In this paper, the data supporting the use of immunoglobulin therapy in lupus nephritis will be evaluated. In addition, the potential mechanisms of action will be discussed with respect to the known involvement of complement and Fc-receptors in the kidney parenchyma. Results are provocative and warrant additional clinical trials.

Abstract
OBJECTIVES Recent studies have shown that mycophenolate mofetil (MMF) is similar to intravenous cyclophosphamide (IVC) for the treatment of lupus nephritis (LN), but that treatment response may vary according to location and race/ethnicity. Moreover, no studies have been conducted to compare the efficacy of MMF with that of IVC for a Japanese population. We therefore conducted a retrospective study to clarify the efficacy and safety of MMF compared with that of IVC for induction therapy for active LN, classes III and IV, in a Japanese population of 21 patients, 11 of whom received MMF and 10 IVC. METHODS The primary endpoint was expressed as the percentage of responders, who in turn were defined as the patients who met complete or partial response criteria according to the European consensus statement. The secondary endpoints comprised the renal activity component and serological activity. RESULTS The primary endpoint was achieved in nine (81.8 %) patients receiving MMF and in four (40.0 %) receiving IVC, with no significant difference between the two groups (p = 0.081), while there was also no significant difference between them in terms of secondary endpoints. However, the MMF group suffered significantly fewer hematologic toxic effects than the IVC group. CONCLUSIONS MMF may be used as an alternative to IVC for inducing renal remission of LN in Japanese patients.

Abstract
Systemic lupus erythematosus (SLE) and small-sized vessel vasculitis are usually two distinguishable autoimmune diseases. However, a vasculitis may be found in the course SLE but rarely corresponds to an ANCA-associated vasculitis (AAV). We report four cases of de novo SLE associated with AAV, our aim being to discuss the clinical significance of this association. We included four patients fulfilling the criteria for both SLE and AAV and followed in two different university hospitals between 1996 and 2009. In light of a 20-year literature review (25 described clinical cases), we discussed the etiopathogeny of such an association. All patients presented a severe renal involvement (creatininemia ranging from 120 to 370 μmol/l) and thrombopenia (ranging from 45,000 to 137,000 platelets/mm(3)). The other main clinical symptoms were arthritis (n = 3), serositis (n = 2) and intra-alveolar hemorrhage (n = 2). An inflammatory syndrome was noticed at diagnosis in all cases. ANCAs were MPO-ANCAs in all cases. Two out of these four patients were also diagnosed with antiphospholipid syndrome. The frequency of this association seems not fortuitous. Although the etiopathogenic mechanisms of such an association remain to be more precisely described, several clinical, histological and immunological features support the hypothesis of the existence of a SLE-AAV overlapping syndrome. Moreover, clinicians must be aware of such an overlapping syndrome, notably because its initial presentation can be very severe.

Abstract
Intravenous immunoglobulins (IVIg) were first introduced in the middle of the twentieth century for the treatment of primary immunodeficiencies. In 1981, Paul Imbach noticed an improvement of immune-mediated thrombocytopenia, in patients receiving IVIg for immunodeficiencies. This opened a new era for the treatment of autoimmune conditions with IVIg. Since then, IVIg has become an important treatment option in a wide spectrum of diseases, including autoimmune and acute inflammatory conditions, most of them off-label (not included in the US Food and Drug Administration recommendation). A panel of immunologists and internists with experience in IVIg therapy reviewed the medical literature for published data concerning treatment with IVIg. The quality of evidence was assessed, and a summary of the available relevant literature in each disease was given. To our knowledge, this is the first all-inclusive comprehensive review, developed to assist the clinician when considering the use of IVIg in autoimmune diseases, immune deficiencies, and other conditions.

Abstract
There are few clinicopathologic and outcome data on patients with crescentic lupus nephritis, therefore, we determined factors of the disease by retrospectively reviewing the records of 327 patients diagnosed with lupus nephritis. Of these, 152 cases were regrouped as class IV-G, including 33 patients with crescentic glomerulonephritis. Significantly, all patients with crescentic glomerulonephritis had acute kidney injury as compared with only about a quarter of the patients without the disease. On pathological evaluation, activity scores, chronicity indexes, relapse rates, and the frequency of positive serum anti-neutrophil cytoplasmic antibody (ANCA) were each significantly higher, whereas complete remission rates and renal outcomes, over a mean follow-up of 4 years, were significantly poorer in patients with crescentic glomerulonephritis. Our study shows that crescentic glomerulonephritis was not rare in patients with lupus nephritis and that their long-term outcome was poor. The precise role of ANCA in the pathologic course of crescentic lupus nephritis remains to be determined.

Abstract
A 19-year-old female was admitted with general malaise and systemic edema. She had been diagnosed as having autoimmune hemolytic anemia (AIHA) eight years earlier and was successfully managed with oral prednisolone. During the current admission, she was diagnosed as having systemic lupus erythematosus (SLE) based on the presence of renal involvement, hematological abnormalities, and antinuclear and anti-double-stranded DNA antibodies, along with a recurrence of AIHA; her serology revealed a high myeloperoxydase-antineutrophil cytoplasmic antibody (MPO-ANCA) titer. She was treated with prednisolone (50 mg day(-1)), but her renal function started to deteriorate. She responded to treatment with hemodialysis, plasmapheresis, and methylprednisolone pulse therapy; her MPO-ANCA titer and renal function improved. Treatment with intravenous cyclophosphamide gradually suppressed her AIHA and SLE activity. A renal biopsy revealed a diffuse proliferative lupus nephritis (class IV-G (A)) with necrotizing crescentic glomerulonephritis that was presumed to be associated with MPO-ANCA. The association of MPO-ANCA with SLE in this refractory case is discussed.

Abstract
BACKGROUND AND OBJECTIVES Lupus nephritis is a classic immune complex glomerulonephritis. In contrast, antineutrophil cytoplasmic antibodies are associated with necrotizing and crescentic glomerulonephritis, in the absence of significant immune deposits. Antineutrophil cytoplasmic antibodies are detected by indirect immunofluorescence in 20% of patients with systemic lupus erythematosus. We report 10 cases of necrotizing and crescentic lupus nephritis with antineutrophil cytoplasmic antibody seropositivity. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Ten patients with systemic lupus erythematosus, antineutrophil cytoplasmic antibody positivity, and renal biopsy findings of lupus nephritis and antineutrophil cytoplasmic antibody-associated glomerulonephritis were identified. The clinical features, pathologic findings, and outcomes are described. RESULTS The cohort consisted of eight women and two men with a mean age of 48.4 yr. Perinuclear antineutrophil cytoplasmic antibody was detected by indirect immunofluorescence in nine patients. Four of the nine patients and the single remaining patient were found to have myeloperoxidase-antineutrophil cytoplasmic antibodies by enzyme-linked immunosorbent assay. Clinical presentation included proteinuria, hematuria, and acute renal insufficiency, with mean creatinine of 7.1 mg/dl. All biopsies exhibited prominent necrosis and crescents with absent or rare subendothelial deposits and were interpreted as lupus nephritis and antineutrophil cytoplasmic antibody-associated glomerulonephritis. All patients received cyclophosphamide and prednisone. Three patients died of infectious complications. Among the remaining seven patients, five achieved a complete or near-complete remission, one had a remission with subsequent relapse, and one had no response to therapy. CONCLUSION Antineutrophil cytoplasmic antibody-associated necrotizing and crescentic glomerulonephritis may occur superimposed on lupus nephritis. In patients with lupus nephritis and biopsy findings of prominent necrosis and crescent formation in the absence of significant endocapillary proliferation or subendothelial deposits, antineutrophil cytoplasmic antibody testing by enzyme-linked immunosorbent assay is recommended.

Abstract
BACKGROUND A recently proposed reclassification of lupus nephritis divides class IV (diffuse proliferative) lupus nephritis into those cases with predominantly segmental proliferative lesions (class IV-S) and those with predominantly global proliferative lesions (class IV-G). This report explores the validity of this distinction and possible differences in pathogenesis between the 2 types of lesions. METHODS Patients from a previously reported series of severe lupus nephritis, with initial biopsies (Bx1) and control biopsies (Bx2) at 6 months after induction therapy were reclassified according to the newly proposed classification. From the original series of 65 patients, 15 patients were reclassified as having class IV-S lesions and 31 patients class IV-G lesions. Clinical data at both biopsies and follow-up were available on all patients selected. RESULTS Patients with IV-G lesions had worse proteinuria, lower serum hemoglobins, lower CH50s, and likely higher SCrs (P = .06) and lower C3s (P = .08) than class IV-S patients. Serum CH50 and C3 correlated negatively with severity of class IV-G lesions, but not at all with class IV-S lesions. Patients with class IV-G lesions had greater overall immune deposits and subendothelial deposits on IF and greater hyaline deposits on light microscopy. By contrast, class IV-S showed predominant mesangial deposits and a much higher rate of glomerular fibrinoid necroses (13.3 +/- 15.3% vs. 5.6 +/- 8.0% of viable glomeruli, P = .03). Other distinctions included the fact that membranoproliferative features were found only in class IV-G lesions, and glomerular monocyte/macrophages were much more frequent in this group than in class IV-S lesions (1.77 +/- 0.92 vs. 0.86 +/- 0.77, P = .008). Finally, class IV-G frequently involved all viable glomeruli (74.2% of cases), whereas segmental proliferative lesions never did (P < .0001). Survivals from doubling of SCr at 10 years did not differ between the 2 types at Bx1: 72.5% segmental versus 60.4% global, P= .53. However, among those with persistent lesions at Bx 2 (11 IV-S and 9 IV-G), there was a dramatic difference in 10-year survivals between IV-S lesions (63.6%) and IV-G lesions (0%), P = .08. CONCLUSION There are definite clinical and morphologic differences between class IV-S and IV-G lesions. Data suggest that class IV-G lesions behave as an immune complex disease, having positive correlations with extent of immune deposits and negative correlations with serum complement levels, the model traditionally assumed for lupus nephritis as a whole. However, in class IV-S lesions, the presence of proportionally greater glomerular fibrinoid necroses and lack of correlation with extent of immune deposits suggest that these lesions may have a different pathogenesis.

Abstract
OBJECTIVES To review the literature on the use and efficacy of intravenous immunoglobulin (IVIG) in glomerulonephritis and to evaluate the nephrotoxic effect of IVIG. METHODS A structured literature search of articles published on the efficacy of IVIG in the treatment of nephritis between 1985 and 2003 was conducted. All articles dealing with lupus nephritis, IgA nephropathy, Henoch Schonlein purpura, antineutrophil cytoplasmic antibodies (ANCA) associated vasculitis, primary membranous glomerulonephritis, and primary chronic nephritis were reviewed. The same literature search was conducted for the nephrotoxic effects of IVIG. Two groups of patients were defined: (a) a group of patients with IVIG nephrotoxic effect published as case reports, and (b) a group of patients whose data were collected by the Food and Drug Administration (FDA). All existing data of both groups were pooled and compared. RESULTS One hundred six patients with lupus nephritis were treated with IVIG. In most reports proteinuria, nephrotic syndrome, and values of creatinine clearance were improved. In 3 cases improvement in World Health Organization (WHO) class was noted, and in 2 cases a reduction of immune deposits was demonstrated. In the other forms of autoimmune nephropathy, although the number of reported cases was small, improvement was noted in most patients. Thirty-two reports entailing 78 patients with IVIG-induced nephrotoxicity were found and their data were compared with those of 88 patients reported to the FDA. No specific differences were noted between the 2 groups of patients, as their age and indications for using IVIG were similar. Most of the patients who developed renal toxicity (72% in the literature and 90% in the FDA group) received sucrose -containing IVIG products. A high percentage of patients (31% in the literature and 40% in the FDA group) required hemodialysis. Mortality occurred in 10 and 15%, respectively. Renal histology done in a minority of the cases demonstrated vacuolization and swelling of the proximal tubules consistent with osmotic injury. CONCLUSIONS On one hand, there are encouraging reports on the efficacy of IVIG in different types of glomerulonephritis (mainly lupus nephritis) resistant to conventional therapy, but the exact success rate and clinical indications remain undetermined. On the other hand, IVIG and the kidney is a two-edged sword, since nephrotoxicity can be a serious rare complication of IVIG therapy. Products containing sucrose as a stabilizer are mainly associated with such injury through the mechanism of osmotic nephrosis. Preexisting renal disease, volume depletion, and old age are risk factors for such toxicity.

Abstract
Rheumatologic emergencies may pose a serious threat to life, and the treatment of patients with these illnesses continues to be challenging. In the last decade extensive animal and human research has led to development of new therapies. Considerable progress has been made in the therapy for RA. Newly developed biologic therapies have shown promising results in clinical studies, and two agents have already been approved by the FDA. These drugs are currently available for therapy and are under close postmarketing scrutiny to assess long-term efficacy and safety. Similar therapies are under investigation for SLE. Plasmapheresis, once used for many diseases, is now restricted mostly to conditions for which its use has been shown to be beneficial in randomized, controlled studies. Immunoadsorption is used to target specific disease-producing pathogens for removal during extracorporeal therapy. Evidence is accumulating for the use of IVIGs in several immune-mediated conditions. The outlook for some emergencies continues be grim, however, and various therapies are used based on evidence from anecdotal case reports and case series. The new therapies are relatively safe, but careful monitoring is needed, because there is potential for serious adverse events.
