Abstract
We present a case of a 52-year-old woman who had transient speech impediment and progressive numbness, weakness, and a purpuric rash affecting her limbs, with severe joint pains. Because she had a chest infection two weeks prior, her clinical presentation gave rise to a suspicion of post-infective vasculitis or post-infective polyneuritis. Further investigation proved this to be eosinophilic granulomatosis with polyangiitis (EGPA) presenting with purpura, mononeuritis multiplex, and cerebral infarction. Treatment with glucocorticoids and cyclophosphamide led to rapid remission. This case highlights the potential difficulty in diagnosing EGPA because of its multiple clinical manifestations and emphasizes the importance of a thorough review of the past medical history.

Abstract
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) refers to a group of disorders characterized by inflammation and destruction of small- and medium-sized blood vessels. It can be classified into various clinical disease phenotypes: granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA), and renal-limited AAV or serologic subtypes, which are myeloperoxidase (MPO)-AAV and proteinase 3 (PR3)-AAV. Renal involvement is a common manifestation in these types of vasculitis. MPO-AAV usually involves the glomeruli causing membranous changes and presents with glomerulonephritis. However, MPO-AAV renal type without glomeruli involvement is much rarer, and very few case reports of this condition have been reported in the literature. Once the diagnosis is confirmed by renal biopsy, the treatment of AAV involves high-dose steroids and cyclophosphamide to induce remission. Rituximab, a chimeric monoclonal antibody that targets against the pan-B-cell marker CD20, was the first monoclonal antibody to be approved for the treatment of vasculitis. It is now considered first-line therapy for ANCA vasculitis with kidney involvement thanks to the higher remission rates associated with it. We report a unique and rare case of acute kidney injury due to MPO-AAV without glomeruli involvement, which was successfully treated with rituximab over a period of 12 months and led to the remission of the disease in the kidneys.

Abstract
In this article, we present an unusual case of granulomatosis with polyangiitis (GPA) in a 41-year-old man. The initial presentation of the disease was atypical, with persistent fever, cough, and fatigue, accompanied by elevated inflammatory markers in association with a large, solitary lung lesion observed at the chest X-ray. Despite the presence of an initial radiological picture suggesting pneumonia, the lack of response to antibiotics necessitated a more in-depth evaluation. The diagnosis was confirmed through a lung biopsy and serological tests positive for anti-neutrophil cytoplasmic antibodies (c-ANCA). GPA is an anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, a systemic autoimmune disease characterized by necrotizing granulomatous inflammation and pauci-immune small vessel vasculitis. This case posed diagnostic challenges due to the atypical presentation, initially mistaken for a respiratory tract infection versus cancer. However, the lack of improvement with antibiotics and persistent inflammation raised suspicions of an underlying complex condition. The diagnosis was confirmed through a lung biopsy and positive c-ANCA serological tests. The patient had reported a prior SARS-CoV-2 infection, raising questions about the possible connection between COVID-19 and GPA, as suggested by previous studies. The diagnostic workup ruled out common and rare pulmonary infections, autoimmune diseases, and neoplasms. However, the presence of positive c-ANCA antibodies was pivotal for the GPA diagnosis. Treatment involved the use of high-dose corticosteroids and rituximab to suppress the autoimmune response. Early diagnosis and timely treatment are essential for improving outcomes in patients with GPA.

Abstract
Granulomatosis with polyangiitis (GPA), previously Wegener's granulomatosis, is a necrotizing vasculitic disease process affecting the small- and medium-sized blood vessels. GPA is frequently associated with damage to the respiratory tract and kidneys but often affects other organ systems including the eyes, nasopharynx, and nervous system. Due to the vague nature of presenting symptoms and the progressive nature of GPA, it is essential to keep a broad differential to mitigate the high morbidity and mortality associated with the disease. Here we introduce a case of a GPA presenting as respiratory distress, stridor, and renal injury. We also review common clinical presentations, diagnostic evaluation, and treatment options.

Abstract
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis comprises several conditions involving vascular destruction that extends into tissue necrosis. There are several autoimmune and environmental causes implicated in the disease progression; among these is drug-induced vasculitis caused by hydralazine use. Hydralazine-induced vasculitis is an uncommon potential complication of the medication and can progress to multisystem involvement and eventually advance to end-organ damage and renal failure. Our patient presented with symptoms of lower extremity edema, dyspnea, and a nonproductive cough eventually resulting in the identification of hydralazine-induced ANCA-associated vasculitis with hypocomplementemia and positive anti-histone antibody. Due to the prevalence of hydralazine as a cardiac drug, physicians managing patients on the medication should have a high index of suspicion of the potential for vasculitis in order to promote prompt diagnosis and treatment of the ANCA-vasculitis.

Abstract
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a necrotizing vasculitis disease that traditionally includes three variants classified based on their clinical and pathological appearance: microscopic polyangiitis (MPA), granulomatosis with polyangiitis, and eosinophilic granulomatosis with polyangiitis (alternatively, Churg-Strauss syndrome). The mainstay of AAV treatment is immunosuppressive treatments, which improve survival and lower rates of end-stage kidney disease. Here we describe a patient with MPA ANCA who presented with diffuse alveolar hemorrhage and, six months later, recurrent pulmonary hemorrhage with renal sparing while off therapy.

Abstract
A 79-year-old man presented with dyspnea upon exertion, marked renal dysfunction, proteinuria, and hematuria. He was diagnosed with rapidly progressive glomerulonephritis. Serological tests were positive for MPO-ANCA, PR3-ANCA, and anti-GBM antibodies. Since the anti-GBM antibody titer was significantly higher than the ANCA titer and the renal dysfunction was severe, we initially assumed anti-GBM disease and started treatment. Due to poor general condition, a definitive diagnosis could not be made by renal biopsy. Corticosteroid therapy, plasmapheresis, and cyclophosphamide treatment were performed. However, renal function did not improve, and hemodialysis was required. He died of sepsis during treatment. An autopsy was performed with the consent of the family. Renal pathological examination revealed fibrocellular crescent formation in the glomeruli. Immunofluorescence revealed no major deposition in the glomeruli, suggesting ANCA-associated nephritis but not anti-GBM disease. Gross pathological findings of the abdominal aorta showed that a part of the artificial blood vessel had formed a pseudoaneurysm and abscess. There is no evidence of inflammatory cell infiltration or vasculitis in the alveoli. Pathological findings in the other organs did not suggest vasculitis. The renal prognosis of this case could have been improved with appropriate treatment if early diagnosis by renal biopsy had been made. There have been case reports of triple-seropositive rapid progressive glomerulonephritis (RPGN). We report a rare autopsy case of triple-seropositive RPGN.

Abstract
A 41-year-old man was admitted to the Emergency Department with bilateral numbness in lower extremities and left femoral palsy. He also reported constitutional symptoms, vomiting and non-bloody diarrhoea for the last several months. He had a previous history of eosinophilic asthma with erratic follow-up. During admission, eosinophil count was 66% of white blood cells. Sural nerve biopsy revealed vasculitis with eosinophilic infiltration. Further evaluations consisted of colonoscopy and nasal endoscopy that confirmed eosinophil infiltrates on colonic ulcers and nasal polypi. The patient was started on systemic corticosteroids and cyclophosphamide. Among his personal records, he had been taking nandrolone decanoate without medical prescription, and had withdrawn a few years before the first asthma exacerbation.

Abstract
Anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV) is a class of small vessel vasculitis that includes granulomatosis with polyangiitis (GPA), eosinophilic GPA (EGPA), and microscopic polyangiitis (MPA). Despite extensive research, the mechanisms behind AAV etiology remain obscure. The genetics of AAV is a complex area of investigation because of the rarity of familial cases. However, recent multi-center genome-wide association studies (GWAS) have greatly contributed to our understanding of the genetic basis of AAV. In this study, we report a rare occurrence of GPA in two Caucasian family members who presented with similar clinical symptoms and performed a comprehensive review to study the present literature available regarding the heritability of this disease.

Abstract
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of disorders that causes severe small-vessel inflammation with systemic manifestations. There are three subtypes of AAV, namely granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic GPA (EGPA). The most commonly affected organs are the upper and lower respiratory tract and the kidneys with occasional and varied neurological manifestations. Here we report a case of a 61-year-old female who presented with a one-month history of numbness, paresthesia, and asymmetric distal weakness of both lower limbs without any bladder or bowel involvement. Similar complaints appeared in her upper limbs three days prior to admission. She also suffered from myalgia, arthralgia, reduced appetite, and lost 8-10 kg weight over the past six months. Her nerve conduction study (NCV) revealed asymmetrical, predominantly motor, mixed, axonal and demyelinating polyneuropathy affecting both lower limbs, which was suggestive of mononeuritis multiplex. After a detailed workup, she tested strongly positive for cytoplasmic ANCA (c-ANCA). Although there was no clinical involvement of the respiratory tract, a contrast-enhanced computed tomography scan of the thorax and abdomen showed multifocal subpleural and lung parenchymal soft tissue lesions and mediastinal and bilateral hilar lymphadenopathy suggestive of a granulomatous lesion. She was diagnosed with the GPA variant of ANCA-associated vasculitis. Remission induction was achieved with high-dose methylprednisolone and cyclophosphamide along with alternate-day cotrimoxazole. Remission was maintained with tapering doses of steroid and mycophenolate mofetil with a slow but sustained recovery. On follow-up after one year, she walked without support with mild residual burning paresthesia in both feet. This case highlights the fact that neurological symptoms can be the presenting manifestation of AAV, and clinicians should have a high level of suspicion for AAV in patients presenting with mononeuritis multiplex, especially after ruling out common causes. By considering such etiologies, it may be possible to diagnose the condition at an earlier stage and initiate treatment to prevent potential pulmonary or renal damage.

Abstract
RATIONALE Pneumocystis pneumonia (PCP) is an opportunistic fungal infection that occurs in people with impaired or suppressed immunity such as patients with human immunodeficiency virus or organ transplant. However, the incidence and characteristics of PCP in the population with long-term hemodialysis is poorly described in the literature. PATIENT CONCERNS We present a case of a 50-year-old female patient being transferred to our hospital in February 2022 with a 20-day history of cough and tight breath. She received amoxicillin and cephalosporin anti-infection treatment successively in local hospital but no significant improvement in symptoms. She had a 2-year history of hemodialysis and no relevant transplantation and human immunodeficiency virus infection. She was diagnosed as ANCA associated vasculitis (AAV) and given oral prednisone acetate (20 mg/day) and methotrexate (2.5 mg/week) half a year ago. DIAGNOSES Based on the patient's medical history, Lung computerized tomography image, the Next generation sequencing report, the patient was diagnosed with renal failure, anti-neutrophil cytoplasmic antibody associated vasculitis, and Pneumocystis pneumonia. INTERVENTIONS The dosage of immunosuppressant was reduced due to leucocyte dripping and fever, and antibiotic and antifungal treatment were also given. The patient's lung condition was getting worse and noninvasive ventilator was required to maintain blood oxygen. Blood filtration is used to remove toxins. Ganciclovir and trimethoprim-sulfamethoxazole was used based on the next generation sequencing report. OUTCOMES The patient died of respiratory failure. LESSONS The risk of PCP in hemodialysis patients may be higher than that in ordinary population, and the prognosis of patients with immunosuppression may be worse. Dynamic assessment of vasculitis activity is necessary for hemodialysis patients with AAV because infections may obscure lung symptoms of AAV. It is not recommended that hemodialysis patients with long-term immunosuppression should reduce or stop the dosage of immunosuppressive drugs during the treatment because it may aggravate the condition of PCP. There is still no clear conclusion on whether hemodialysis patients need preventive medicine, but the identification of risk factors and early diagnosis and treatment are important for the prognosis of PCP on hemodialysis population.

Abstract
[Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis] (AAV) is an autoimmune disease characterized by systemic vascular inflammation. We present a case of a 76-year-old man who presented with shortness of breath, fatigue, and weakness. He was eventually diagnosed with hydralazine-induced ANCA-associated renal limited glomerulonephritis. The presentation of this case was unique for a few reasons; the patient showed an initial improvement in kidney function, was non-oliguric, and had no systemic signs of vasculitis. This led to the patient being discharged prematurely with the diagnosis of acute tubular necrosis. We discuss educational features of this case and warn future clinicians about the possibility of waxing and waning renal function in these patients, as well as the importance of having a higher index of suspicion for glomerulonephritis in patients who take hydralazine.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection triggers elevated levels of circulating cytokines and immune-cell hyperactivation, called a cytokine storm, which leads to dysregulated immune response not only towards the pathogen itself but also contributes to cellular, vascular injury and multiorgan dysfunction. The cytokine-induced endothelial inflammation and vascular pathology of COVID-19 is well reported in post-mortem biopsies and several cases reporting small, medium and large vessel micro/macro thrombotic events and vasculitis in multiple organs. So far, few cases have been reported with newly diagnosed antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis at the time of acute COVID-19 infection. The exact pathophysiology of SARS-CoV-2 and ANCA-associated vasculitis continues to be studied and reviewed. Here we report a case of a 60-year-old female who presented to our institution with sudden onset of shortness of breath and hemoptysis. A detailed history revealed a recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Labs showed elevated serum creatinine, urine analysis with large blood and nephrotic range proteinuria. CT chest was remarkable for abnormal appearance of the parenchyma bilaterally compatible with a crazy paving pattern, suggesting pulmonary alveolar proteinosis versus diffuse alveolar hemorrhage. Vasculitis was suspected and the patient was started on IV corticosteroids and plasmapheresis. Diagnostic workup was positive for antineutrophil cytoplasmic antibodies-myeloperoxidase (ANCA-MPO), anti-Sjögren's syndrome-related antigen A autoantibodies (anti-SS-A) and antinuclear antibodies (ANA). Renal biopsy confirmed focal segmental necrotizing, crescentic and sclerosing glomerulonephritis, pauci-immune type, anti-MPO antibody/P-ANCA associated. A diagnosis of microscopic polyangiitis was made and she was started on rituximab immunosuppressive therapy following which she showed clinical improvement. In this document, we present a unique case of microscopic polyangiitis possibly induced by SARS-CoV-2 infection confirmed by renal biopsy and clinical presentation. In the current setting of a global pandemic, we strongly recommend that vasculitis be high on the differential diagnosis in patients who are currently infected or had been infected with SARS-CoV-2 and present with acute kidney injury (AKI).

Abstract
Objective According to the manufacturer's documentation, rituximab (RTX) should be administered with slow infusion rates to prevent infusion-related adverse events (AEs). Nevertheless, slow infusions are time-consuming and uncomfortable for patients and medical staff. Therefore, faster infusion rates have been studied and proven safe and well tolerated in lymphomas and rheumatoid arthritis (RA). A small amount of data is available for rapid RTX infusions in non-RA autoimmune diseases. Methods Beginning in September 2015, all RTX-reated patients in our centre and willing to participate, were switched from slow RTX infusions (4.25 hours, given at least once to all patients) to fast infusions (2 hours). A total of 85 RTX 2-hour infusions was administered to 53 patients with autoimmune diseases with renal involvement and selected primary glomerulonephritides (26 ANCA-associated vasculitis, nine systemic lupus erythematodes, seven membranous nephropathy, five IgM nephropathy and six other autoimmune disease). Most of the patients received chronic corticosteroid therapy. The prednisone equivalent dose median (IQR) was 0.1 (0.0-0.2) mg/kg/day. Results Rapid RTX infusions were generally well tolerated. Only two infusion-related AEs were recorded: one Common Terminology Criteria for Adverse Events, grade 3, (lower back pain and hypotension followed by chills necessitating methylprednisolone and dipyrone administration) and one grade 1 (subjective intolerance). The AEs frequency does not differ from other studies with rapid RTX infusions in patients with lymphomas and RA. Conclusions Our experience supported other published data and provides evidence concerning the safety of non-initial RTX 2-hour infusion which can be administered without raising the infusion-related AEs rate in patients with kidney-affecting autoimmune diseases and glomerulonephritides.
