RESUMO

Objective: This paper aimed to describe another form of aggressive limited Granulomatosis with polyangiitis (GPA) revealed by dacryoadenitis. Methods and results: We report an unusually limited GPA in a 48-year-old man presenting with bilateral proptosis. She had never presented kidney or pulmonary manifestations, but her disease was persistently active including oto-rhino-laryngological manifestations, dacryoadenitis, and neurological manifestations unresponsive to corticosteroids and immunosuppressors. Discussion: Granulomatosis with polyangiitis (GPA) is an auto-immune inflammatory vasculitis. Involvement of lacrimal glands as the first presentation is uncommon. It is characterized by the development of granulomas. Patients with orbital mass without lacrimal gland involvement have a higher rate of systemic disease, a severe clinical course, and a higher rate of recurrences. A patient with dacryoadenitis seems to be with a good prognosis. Eye manifestations were significantly more common in patients with pachymeningitis. MPO-ANCA-positive pachymeningitis was more frequent in older female patients. PR3-ANCA-positive pachymeningitis had more severe neurological damage. Induction treatment consists of intravenous methylprednisolone (IV) associated with cyclophosphamide. Conclusion: Faced with dacryoadenitis, it is important to screen for ANCA-associated vasculitis. Abbreviations: GPA = Granulomatosis with polyangiitis, ANCA = Antineutrophil Cytoplasmic Antibodies.

RESUMO

Conventional immunosuppressants are ineffective for the management of EGPA-related asthma. Tezepelumab is a human monoclonal antibody that inhibits thymic stromal lymphopoietin (TLSP) that has proven efficacy in several phase 3 studies for the treatment of asthma. We treated with off-label tezepelumab the first two patients with severe refractory EPGA-related asthma. These preliminary findings suggest that targeting upstream signaling of the T2 inflammatory pathway can improve symptoms, reduce BVAS and increase Asthma Control Test scores, even in patients with refractory asthma who have failed several previous lines of treatment. Nevertheless, by analogy with dupilumab-induced IL-4/13 blockade, the persistence of sputum eosinophilia (reported in both patients) raises questions as to whether TSLP inhibition could lead to a rebound of eosinophilia and potentially to eosinophil-related symptoms in patients with EGPA.

RESUMO

Objective: To explore the clinical characteristics and treatment outcomes of children with central nervous system (CNS) involvement in eosinophilic granulomatosis with polyangiitis (EGPA). Methods: A child who presented with EGPA complicated by CNS involvement was admitted to our hospital in June 2023. The clinical features were analyzed retrospectively, and relevant literatures were reviewed to provide a comprehensive overview of this condition. Results: A ten-year-old girl, who had a history of recurrent cough and asthma accompanied by peripheral blood eosinophilia for eight months, was admitted to our hospital. On admission, spotted papules were visible on her hands and feet, bilateral pulmonary rales were audible. The laboratory examination revealed that the proportion of eosinophils (EOS) exceeded 10% of white blood cells, the anti-neutrophil cytoplasmic antibody (MPO-ANCA) was positive, the immunoglobulin G level was 15.80g/L, and the immunoglobulin E level was greater than 2500.00IU/mL. The imaging examination showed multiple patchy and nodular high-density shadows in both lungs as well as sinusitis. Pulmonary function tests indicated moderate ventilation and diffusion dysfunction. Bone marrow cytology demonstrated a significant increase in the proportion of eosinophils. Skin pathology confirmed leukocytoclastic vasculitis. During the hospitalization, the child had a convulsion. The magnetic resonance imaging (MRI) scan of the brain showed multiple abnormal signal shadows in the bilateral cerebral cortex and the electroencephalogram (EEG) showed epileptic waves. Following the administration of methylprednisolone pulse therapy in combination with cyclophosphamide treatment, her cough and asthma resolved, the skin rash disappeared without any further convulsions. We found that only a young EGPA patient with CNS involvement had been previously reported. The previously reported case began with long-term fever, weight loss, and purpuric rash. Both patients responded well to treatment with glucocorticoids and cyclophosphamide, experiencing significant improvement in their clinical symptoms and normalization of their peripheral blood eosinophils. Conclusion: The diagnosis of EGPA in children can be challenging. When a child is affected by EGPA, it is essential to remain vigilant for signs of CNS involvement. The treatment with glucocorticoids and cyclophosphamide is effective in managing EGPA in children.

RESUMO

The association between the use of certain medications (including sulfonamides, hydralazine, and procainamide) and the occurrence of drug-induced lupus or hepatitis is well established. More recently, cases of immune-related adverse events ranging from inflammatory polyarthritis to necrotizing myositis in patients taking checkpoint inhibitors have been reported. However, data linking drugs to systemic vasculitis are scarce and at times debatable. Propylthiouracil, hydralazine, and minocycline have been associated with rare cases of ANCA-associated syndromes, including life-threatening pulmonary-renal syndromes and systemic polyarteritis nodosa-like diseases. Eosinophilic granulomatosis with polyangiitis (EGPA) has been reported in patients taking leukotriene inhibitors. Since the link between the use of leukotriene inhibitors and occurrence of EGPA remains highly controversial, we performed a literature review for cases of EGPA in patients taking montelukast without prior history of oral corticosteroid use. We found 24 cases, along with our own two cases described, making 26 cases in total. The mean age was 43 and a majority (18/26) were female. In majority of cases EGPA-like disease never relapsed after they were taken off leukotriene inhibitors suggesting a clear causal relationship between the use of these drugs and occurrence of eosinophil-rich systemic EGPA.

RESUMO

Granulomatosis with polyangiitis is a systemic vasculitis. While the classic triad typically comprises otorhinolaryngologic, pulmonary, and renal manifestations, it is essential to recognize that granulomatosis with polyangiitis can affect any organ. Furthermore, reports have documented less common sites of involvement, such as the gastrointestinal tract. In this case-based review, we focus on a case of granulomatosis with polyangiitis presenting with intestinal perforation and the added challenge of concurrent pancytopenia.A 25-year-old female was diagnosed with granulomatosis with polyangiitis, with her clinical course progressing from joint pain to severe multi-organ involvement, including gastrointestinal complications. Treatment challenges emerged with the development of pancytopenia. While this may not directly result from granulomatosis with polyangiitis, it introduced an additional layer of complexity and delayed the induction of remission with immunosuppressants. Despite initial stabilization, an unexpected jejunal perforation occurred, requiring surgical intervention and subsequent postoperative care. The case underscores the complex nature of granulomatosis with polyangiitis and its potential complications. A literature search yielded discrete relevant cases in the context of our patient's intricate presentation, which has been summarized.We highlight the complexities in diagnosing and managing granulomatosis with polyangiitis-related complications, especially in uncommon presentations, and emphasize the importance of a personalized approach to patient care in these circumstances.

RESUMO

Proteinase 3 (PR3)-specific antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is one of two major ANCA-associated vasculitis variants and is pathogenically linked to granulomatosis with polyangiitis (GPA). GPA is characterised by necrotising granulomatous inflammation that preferentially affects the respiratory tract. The small vessel vasculitis features of GPA are shared with microscopic polyangiitis. Necrotising granulomatous inflammation of GPA can lead to PR3-ANCA and small vessel vasculitis via activation of neutrophils and monocytes. B cells are central to the pathogenesis of PR3-ANCA-associated vasculitis. They are targeted successfully by remission induction and maintenance therapy with rituximab. Relapses of PR3-ANCA-associated vasculitis and toxicities associated with current standard therapy contribute substantially to remaining mortality and damage-associated morbidity. More effective and less toxic treatments are sought to address this unmet need. Advances with cellular and novel antigen-specific immunotherapies hold promise for application in autoimmune disease, including PR3-ANCA-associated vasculitis. This Series paper describes the inter-related histopathological and clinical features, pathophysiology, as well as current and future targeted treatments for PR3-ANCA-associated vasculitis.

RESUMO

OBJECTIVES: Prospective long-term observational data on the disease course of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) were missing in Germany to date. Therefore, the Joint Vasculitis Registry in German-speaking countries (GeVas) has been established to follow the course of patients with AAV. The aim of this study is to present baseline data of patients with newly diagnosed and relapsing AAV enrolled in the GeVas registry. METHODS: GeVas is a prospective, web-based, multicentre, clinician-driven registry for the documentation of organ manifestations, damage, long-term outcomes, and therapy regimens in various types of vasculitis. Recruitment started in June 2019. RESULTS: Between June 2019 and October 2022, 266 patients with AAV were included in the GeVas registry: 173 (65%) with new-onset and 93 (35%) with relapsing AAV. One hundred and sixty-two (61%) patients were classified as granulomatosis with polyangiitis (GPA), 66 (25%) as microscopic polyangiitis (MPA), 36 (13%) as eosinophilic granulomatosis with polyangiitis (EGPA), and 2 (1%) as renal limited AAV. The median age was 59 years (51-70 years, IQR), 130 (51%) patients were female. Most patients were ANCA positive (177; 67%) and affected by general symptoms, pulmonary, ear nose throat (ENT), renal and neurological involvement. For induction of remission, the majority of patients received glucocorticoids (247, 93%) in combination with either rituximab (118, 45%) or cyclophosphamide (112, 42%). CONCLUSIONS: Demographic characteristics are comparable to those in other European countries. Differences were found regarding ANCA status, frequencies of organ manifestations, and therapeutic regimens. The GeVas registry will allow longitudinal observations and prospective outcome measures in AAV.

RESUMO

Granulomatosis with polyangiitis (GPA) is an uncommon disorder that mainly involves the upper and lower respiratory tract and kidney, presenting as sinusitis, saddle nose, otitis media, pulmonary nodule and cavity, rapidly progressive glomerulonephritis. It also affects skin, eye, heart, joint and nervous system. Renal involvement in GPA is commonly manifested as necrotising glomerulonephritis, while renal mass is very rare. We herein present two hospitalised cases with fever, pulmonary cavity and renal mass. Clinical course and examinations of the cases, from symptoms to diagnosis, will be discussed in detail, along with a relevant literature review of this unusual renal manifestation.

RESUMO

OBJECTIVE: To report on a series of patients with cANCA/PR3-positive, granulomatosis with polyangiitis (GPA)-associated subglottic stenosis (SGS) and evaluate response to medical maintenance therapy with rituximab versus other immunosuppressants following initial endoscopic laser excision. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary academic center. METHODS: A retrospective chart review of patients with SGS and cANCA/PR3-positive GPA who received immunosuppressive maintenance therapy following endoscopic laser excision at our institution from June 1989 to March 2020 was performed. Data pertaining to patient demographics, clinical features, medications, and endoscopic laser procedures were collected. RESULTS: A total of 27 patients (15 women) with mean age (range) of 40 (19-59) years and mean (range) follow-up of 12.6 years (1.5-28.6) were identified. Sixteen patients (60%) had limited GPA. Six patients (24%) had previously received local intervention with open surgery (n = 1, 4%) or endoscopic techniques (n = 5, 20%). All patients experienced symptom improvement following initial CO2 laser excision at our institution without any procedural complications or adverse events. Following initial laser excision, 15 patients (60%) were treated with rituximab and 10 patients (40%) were treated with nonrituximab immunosuppressive agents. Patients treated with rituximab were less likely to recur (P = 0.040). Limited GPA was associated with an increased incidence of recurrence (P = 0.031). Median time (years) to recurrence (range) was 3.2 (0.3-19.3) and was not significantly associated with treatment or GPA subtype. CONCLUSION: Endoscopic CO2 laser excision is a safe and effective local intervention for GPA-associated SGS. Medical maintenance therapy with rituximab reduces risk of recurrence following initial laser excision relative to treatment with non-rituximab agents.

RESUMO

BACKGROUND: Microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) are the two major antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). OBJECTIVES: To characterize a homogenous AAV cohort and to assess the impact of clinicopathological profiles and ANCA serotypes on clinical presentation and prognosis. Clinical differences in GPA patients according to ANCA serotype and the diagnostic yield for vasculitis of biopsies in different territories were also investigated. RESULTS: This retrospective study (2000-2021) included 152 patients with AAV (77 MPA/75 GPA). MPA patients (96.1% myeloperoxidase [MPO]-ANCA and 2.6% proteinase 3 [PR3]-ANCA) presented more often with weight loss, myalgia, renal involvement, interstitial lung disease (ILD), cutaneous purpura, and peripheral nerve involvement. Patients with GPA (44% PR3-ANCA, 33.3% MPO, and 22.7% negative/atypical ANCA) presented more commonly with ear, nose, and throat and eye/orbital manifestations, more relapses, and higher survival than patients with MPA. GPA was the only independent risk factor for relapse. Poor survival predictors were older age at diagnosis and peripheral nerve involvement. ANCA serotypes differentiated clinical features in a lesser degree than clinical phenotypes. A mean of 1.5 biopsies were performed in 93.4% of patients in different territories. Overall, vasculitis was identified in 80.3% (97.3% in MPA and 61.8% in GPA) of patients. CONCLUSIONS: The identification of GPA presentations associated with MPO-ANCA and awareness of risk factors for relapse and mortality are important to guide proper therapeutic strategies in AAV patients. Biopsies of different affected territories should be pursued in difficult-to-diagnose patients based on their significant diagnostic yield.

RESUMO

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is a vasculitis characterized by eosinophilic inflammation. Benralizumab, a monoclonal antibody against the interleukin-5α receptor expressed on eosinophils, may be an option for treating EGPA. METHODS: We conducted a multicenter, double-blind, phase 3, randomized, active-controlled noninferiority trial to evaluate the efficacy and safety of benralizumab as compared with mepolizumab. Adults with relapsing or refractory EGPA who were receiving standard care were randomly assigned in a 1:1 ratio to receive benralizumab (30 mg) or mepolizumab (300 mg) subcutaneously every 4 weeks for 52 weeks. The primary end point was remission at weeks 36 and 48 (prespecified noninferiority margin, -25 percentage points). Secondary end points included the accrued duration of remission, time to first relapse, oral glucocorticoid use, eosinophil count, and safety. RESULTS: A total of 140 patients underwent randomization (70 assigned to each group). The adjusted percentage of patients with remission at weeks 36 and 48 was 59% in the benralizumab group and 56% in the mepolizumab group (difference, 3 percentage points; 95% confidence interval [CI], -13 to 18; P = 0.73 for superiority), showing noninferiority but not superiority of benralizumab to mepolizumab. The accrued duration of remission and the time to first relapse were similar in the two groups. Complete withdrawal of oral glucocorticoids during weeks 48 through 52 was achieved in 41% of the patients who received benralizumab and 26% of those who received mepolizumab. The mean (±SD) blood eosinophil count at baseline was 306.0±225.0 per microliter in the benralizumab group and 384.9±563.6 per microliter in the mepolizumab group, decreasing to 32.4±40.8 and 71.8±54.4 per microliter, respectively, at week 52. Adverse events were reported in 90% of the patients in the benralizumab group and 96% of those in the mepolizumab group; serious adverse events were reported in 6% and 13%, respectively. CONCLUSIONS: Benralizumab was noninferior to mepolizumab for the induction of remission in patients with relapsing or refractory EGPA.

RESUMO

PURPOSE: Intravitreal Ganciclovir has been one of the treatments of choice for cytomegalovirus (CMV) retinitis and has been used extensively for its treatment since 1987. It has not been shown to have any major adverse effects. There are no reports on any retinal toxicity even after multiple, repeated injections. Herein, we report a rare case of retinal toxicity after multiple intravitreal injections in a patient of CMV retinitis. CASE REPORT: A 69-year-old one eyed male, who was on oral corticosteroids and systemic immunosuppression for Granulomatosis with Polyangiitis, presented with CMV retinitis in both eyes. His visual acuity was 20/60 in his right eye and no perception of light in his left eye. He was treated with multiple injections of intravitreal Ganciclovir in his right eye. The left eye was not treated since it had no vision potential. The right eye of the patient which had received multiple injections went on to developed a progressive diffuse atrophy of Retinal Pigment Epithelium (RPE). No such changes were noted in the left eye of the patient. CONCLUSION AND IMPORTANCE: We present a case of progressive diffuse RPE atrophy as a result of toxicity of intravitreal ganciclovir injections. It is important to be aware of this rare potential toxicity of intravitreal Ganciclovir.

RESUMO

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis consists of two main diseases, granulomatosis with polyangiitis and microscopic polyangiitis, and remains among the most devastating and potentially lethal forms of autoimmune inflammatory disease. Granulomatosis with polyangiitis and microscopic polyangiitis are characterised by a necrotising vasculitis that can involve almost any organ, and have generally been studied together. The diseases commonly affect the kidneys, lungs, upper respiratory tract, skin, eyes, and peripheral nerves. Granulomatous inflammation and multinucleated giant cells are key pathological hallmarks of granulomatosis with polyangiitis, but are absent in microscopic polyangiitis. Many immune system events are essential to disease aetiopathogenesis, such as activation of the alternative complement pathway, neutrophil activation via complement receptors, and the influx of inflammatory cells, including monocytes and macrophages. These cells perpetuate inflammation and lead to organ damage. During the 21st century, the management of ANCA-associated vasculitis has moved away from reliance on cytotoxic medications and towards targeted biological medications for both the induction and maintenance of disease remission. Earlier diagnosis, partly the result of more reliable ANCA testing, has led to improved patient outcomes and better survival. Reductions in acute disease-related mortality have now shifted focus to long-term morbidities related to ANCA-associated vasculitis and their treatments, such as chronic kidney disease and cardiovascular disease. Therapeutic approaches in both clinical trials and clinical practice still remain too reliant on glucocorticoids, and continued efforts to reduce toxicity from glucocorticoids remain a priority in the development of new treatment strategies.

RESUMO

Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) are two entities of ANCA-associated vasculitis (AAV). Both diseases are characterised by systemic necrotising small-vessel vasculitis, which can affect any organ. In GPA, extravascular necrotising granulomatous inflammation, usually affecting the respiratory tract, is found in addition. In the majority of cases, the clinical presentation is dominated by a pulmonary-renal syndrome with alveolar haemorrhage and rapidly progressive glomerulonephritis. Other organ involvement is found as well. In GPA, the upper respiratory tract is commonly affected. GPA is associated with anti-neutrophil cytoplasmic autoantibodies (ANCA) with specificity for proteinase 3 (PR3-ANCA) and MPA with specificity for myeloperoxidase (MPO-ANCA).

RESUMO

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystemic disease characterized by eosinophilic tissue inflammation. Benralizumab, an anti-IL-5 receptor (anti-IL-5R) monoclonal antibody, induces rapid depletion of eosinophils; its longer-term effect in EGPA is unknown. OBJECTIVE: To assess the real-world effectiveness and clinical remission rates of anti-IL-5R therapy in EGPA. METHODS: We performed a retrospective cohort analysis of patients with EGPA, who commenced treatment with benralizumab. Clinical remission, assessed at 1 year and 2 years after the initiation of benralizumab, was defined as an absence of active vasculitis (Birmingham Vasculitis Activity Score of 0) and an oral corticosteroid (OCS) dose of ≤4 mg/d of prednisolone. "Super-responders" were defined as patients in remission and free of any significant relapses (asthma or extrapulmonary) over the preceding 12 months. The corticosteroid-sparing capacity of benralizumab, patient-reported outcome measures, and characteristics associated with clinical remission and super-responder status were also analyzed. RESULTS: A total of 70 patients completed at least 1 year of treatment with benralizumab, of whom 53 completed 2 years. Of 70 patients, 47 (67.1%) met the definition for clinical remission at 1 year, with a similar proportion in remission at 2 years. Excluding asthma-related relapses, 61 of 70 (87.1%) patients were relapse free at 1 year, and of the 53 who completed 2 years, 45 (84.9%) were relapse free. A total of 67.9% of patients no longer needed any OCS for disease control. No significant difference was seen between antineutrophilic cytoplasmic antibody (ANCA)-positive and ANCA-negative subgroups. CONCLUSIONS: In this real-world setting of patients with EGPA, treatment with benralizumab was well tolerated and resulted in corticosteroid-free clinical remission for the majority of patients.

RESUMO

OBJECTIVE: Although sporadic case reports have demonstrated successful management of eosinophilic granulomatosis with polyangiitis (EGPA) by anti-IL-5 therapy, larger-scale monocentric studies for the efficacy of mepolizumab (MEP), an IL-5 monoclonal antibody, are still lacking in Taiwan. METHODS: Hospitalized EGPA patients aged at least 18 years were enrolled from November 1998 to October 2023, and analyzed for demographic, clinical, laboratory, medication and outcome data, focusing on the efficacy and safety of biologics use, particularly induction therapy with MEP. RESULTS: Twenty-seven EGPA patients aged 10-70 years (43 ± 15) at disease diagnosis were recruited with 21 under combined corticosteroids/cyclophosphamide induction therapy. Seventeen patients received biologics with 13 under MEP therapy. Ten patients aged 19-71 years (48 ± 15) completed 12-month induction therapy with a 100 mg quadri-weekly subcutaneous injection regimen indicated for active or relapse disease. There were reduced BVAS with complete remission in 6 and partial remission in 4 patients, lower CRP levels, decreased eosinophil counts with an inhibition of 92∼96 %, and tapered prednisolone dosages from 5 to 25 (13.0 ± 6.3) to 0-10 (3.3 ± 3.1) mg/day. Only one patient had an adverse event of injection site reactions. Nine patients received the same regimen for annual maintenance therapy. All had a persistent clinical remission. In these patients, 13-56 injections (41 ± 15) were prescribed with a follow-up period of 12∼52 months (38 ± 14). CONCLUSION: In this retrospective study, induction therapy with a 12-month 100 mg MEP quadri-weekly subcutaneous injection regimen demonstrates the efficacy and safety for active and relapsing EGPA patients.

RESUMO

RATIONALE: Granulomatosis with polyangiitis (GPA) is a systematic autoimmune disease. The typical clinical involvement of GPA entails the upper and lower respiratory tracts, and the kidneys. Gastrointestinal (GI) involvement is uncommon and unless detected and treated promptly, may lead to life-threatening complications such as perforation. We aim to review all available publications since the first description in 1982 dealing with GI perforation in patients with Wegener granulomatosis and draw attention to this serious situation. PATIENT CONCERNS: We present a 54-year-old man diagnosed with GPA who presented initially with nasal symptoms and suffered ileal perforation following Corona Virus Disease 2019 infection. We also review previously reported patients with Wegener granulomatosis who had GI perforation to investigate the perforation site and period, pathology, diagnosis, and treatment methods. DIAGNOSES AND INTERVENTIONS: The case of a GPA-diagnosed patient who presented initially with nasal symptoms and suffered ileal perforation following Corona Virus Disease 2019 infection. We recommended a renal puncture biopsy, steroids, and immunosuppressants to improve the patient condition. The patient and his family refused these treatment recommendations. OUTCOMES: Our patient exhibited continued progressive vascular inflammatory changes and eventual irreversible systemic damage. These sequelae were attributed to the patient declining prednisolone and immunosuppressant therapy. LESSONS: GI perforation is rare in GPA but severe complication. Consequently, we recommend that early diagnosis and treatment with steroid hormones and immunosuppressants for GPA patients with GI perforation.
