Rituximab versus azathioprine for maintenance of remission for patients with ANCA-associated vasculitis and relapsing disease: an international randomised controlled trial.

Objective: Following induction of remission with rituximab in anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) relapse rates are high, especially in patients with history of relapse. Relapses are associated with increased exposure to immunosuppressive medications, the accrual of damage and increased morbidity and mortality. The RITAZAREM trial compared the efficacy of repeat-dose rituximab to daily oral azathioprine for prevention of relapse in patients with relapsing AAV in whom remission was reinduced with rituximab.

Human leukocyte antigen association with azathioprine-induced drug hypersensitivity reactions in patients with anti-neutrophil cytoplasmic antibody associated vasculitis.

Azathioprine (AZA) drug hypersensitivity reaction (DHR) is an uncommon yet potentially lethal condition that often goes unrecognised in patients with anti-Neutrophil Cytoplasmic Antibody (ANCA) associated vasculitis (AAV). We conducted a retrospective review of AAV patients on AZA maintenance therapy (N = 35). Participants were categorised into those who had experienced AZA-DHR (N = 15) and those who were AZA-tolerant (N = 20).

Plasma exchange and glucocorticoids to delay death or end-stage renal disease in anti-neutrophil cytoplasm antibody-associated vasculitis: PEXIVAS non-inferiority factorial RCT.

Background: Anti-neutrophil cytoplasm antibody-associated vasculitis is a multisystem, autoimmune disease that causes organ failure and death. Physical removal of pathogenic autoantibodies by plasma exchange is recommended for severe presentations, along with high-dose glucocorticoids, but glucocorticoid toxicity contributes to morbidity and mortality. The lack of a robust evidence base to guide the use of plasma exchange and glucocorticoid dosing contributes to variation in practice and suboptimal outcomes.

The Sound of Interconnectivity; The European Vasculitis Society 2022 Report.

The first European Vasculitis Society (EUVAS) meeting report was published in 2017. Herein, we report on developments in the past 5 years which were greatly influenced by the pandemic. The adaptability to engage virtually, at this critical time in society, embodies the importance of networks and underscores the role of global collaborations.

The effects of plasma exchange in patients with ANCA-associated vasculitis: an updated systematic review and meta-analysis.

Objective: To assess the effects of plasma exchange on important outcomes in anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV).

Design: Systematic review and meta-analysis of randomised controlled trials.

Eligibility Criteria: Randomised controlled trials investigating effects of plasma exchange in patients with AAV or pauci-immune rapidly progressive glomerulonephritis and at least 12 months' follow-up.

Characteristics and significance of "green snake" bites in Myanmar, especially by the pit vipers Trimeresurus albolabris and Trimeresurus erythrurus.

Snakebite is an important problem in Myanmar. Regionally, bites by Eastern Russell's vipers, Daboia siamensis (Viperidae, Viperinae), and monocled cobras, Naja kaouthia are considered medically important, but those categorised as "green snake" bites are not. However, these may include bites by green pit vipers, Trimeresurus spp.

Treatment preferences for primary membranous nephropathy: Results of a multinational survey among nephrologists in the South Asia Pacific region.

Aim: There is no clear consensus on how best to treat primary membranous nephropathy (PMN). This study aimed to ascertain prevailing views among nephrologists on their choice of immunosuppressive agents to treat this disease.

Methods: The Australasian Kidney Trials Network conducted a multinational online survey among nephrologists from the South Asia-Pacific region to identify prescribing practices to treat PMN.

Rituximab as therapy to induce remission after relapse in ANCA-associated vasculitis.

Objectives: Evaluation of rituximab and glucocorticoids as therapy to induce remission after relapse in ANCA-associated vasculitis (AAV) in a prospective observational cohort of patients enrolled into the induction phase of the RITAZAREM trial.

Methods: Patients relapsing with granulomatosis with polyangiitis or microscopic polyangiitis were prospectively enrolled and received remission-induction therapy with rituximab (4×375 mg/m) and a higher or lower dose glucocorticoid regimen, depending on physician choice: reducing from either 1 mg/kg/day or 0.5 mg/kg/day to 10 mg/day by 4 months.

Clinical importance of the Mandalay spitting cobra (Naja mandalayensis) in Upper Myanmar - Bites, envenoming and ophthalmia.

Examination of 18 cobras brought to three hospitals in the Mandalay Region by patients bitten or spat at by them distinguished 3 monocled cobras (Naja kaouthia) and 15 Mandalay spitting cobras (N. mandalayensis), based on their morphological characteristics. We confirm and extend the known distributions and habitats of both N.

Plasma Exchange and Glucocorticoids in Severe ANCA-Associated Vasculitis.

Background: More effective and safer treatments are needed for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis.

Methods: We conducted a randomized trial with a 2-by-2 factorial design to evaluate the use of plasma exchange and two regimens of oral glucocorticoids in patients with severe ANCA-associated vasculitis (defined by an estimated glomerular filtration rate of <50 ml per minute per 1.73 m of body-surface area or diffuse pulmonary hemorrhage).

Tracheobronchial calcification on bronchoscopy in a patient with end stage renal failure: an unusual cause of chronic cough.

Pulmonary calcification can develop as a complication of end-stage renal failure. Most patients are asymptomatic, with characteristic parenchymal changes incidentally detected on computed tomography (CT) imaging and a clinical course that is usually benign. In this report, we describe a 64-year-old female with a history of inadequate peritoneal dialysis who presented with severe chronic cough, a symptom that persisted despite treatment for respiratory tract infection.

Inadequate knowledge about snakebite envenoming symptoms and application of harmful first aid methods in the community in high snakebite incidence areas of Myanmar.

Introduction: Every year millions of people in developing countries suffer from snakebite, causing a large number of deaths and long term complications. Prevention and appropriate first aid could reduce the incidence and improve the health outcomes for those who suffer bites. However, many communities where snakebite is a major issue suffer from a lack of information about prevention and first aid measures that a family or community member could take to prevent severe envenoming, complications and poor outcomes.

Mycophenolate mofetil versus cyclophosphamide for remission induction in ANCA-associated vasculitis: a randomised, non-inferiority trial.

Objectives: Cyclophosphamide induction regimens are effective for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), but are associated with infections, malignancies and infertility. Mycophenolate mofetil (MMF) has shown high remission rates in small studies of AAV.

Methods: We conducted a randomised controlled trial to investigate whether MMF was non-inferior to cyclophosphamide for remission induction in AAV.

A comprehensive approach to managing a neglected, neglected tropical disease; The Myanmar Snakebite Project (MSP).

Snakebite is predominantly an occupational disease affecting poor rural farmers in tropical regions and was recently added to the World Health Organisation list of Neglected Tropical Diseases (NTD). We document an overview of methodologies developed and deployed in the Myanmar Snakebite Project, a foreign aid project largely funded by the Australian Government, with the core aim to "improve outcomes for snakebite patients". A multidisciplinary team of experts was assembled that worked in a collaborative manner with colleagues in Myanmar, first to identify problems related to managing snakebite and then develop interventions aimed to improve selected problem areas.

Twelve month prospective study of snakebite in a major teaching hospital in Mandalay, Myanmar; Myanmar Snakebite Project (MSP).

The Myanmar Snakebite Project is an Australian government (Department of Foreign Affairs and Trade) supported foreign aid project in collaboration with the Myanmar government with the aim of improving outcomes for snakebite patients in Myanmar. As part of the project a case record database was established to document prospective cases of snakebite presenting to Mandalay General Hospital, in Upper Myanmar. The study period was 12 months (1-2-2016 to 31-1-2017).

Development of an ELISA assay to determine neutralising capacity of horse serum following immunisation with Daboia siamensis venom in Myanmar.

Snakebite envenoming is a serious problem in Myanmar. The great majority of snakebite in this country is due to Russell's Viper (Daboia siamensis). For many years, the Burma Pharmaceutical Industry has produced a monovalent antivenom to Russell's Viper in horses.

Snakebite incidence in two townships in Mandalay Division, Myanmar.

Introduction: The global incidence of snakebite is estimated at more than 2.5 million cases annually, with greater than 100,000 deaths. Historically, Myanmar has one of the highest incidences of venomous snakebites.

Why snakebite patients in Myanmar seek traditional healers despite availability of biomedical care at hospitals? Community perspectives on reasons.

Background: Snakebite is a major public health problem in many developing countries. Farmers are particularly exposed to snakes, and due to their rural location often experience delays in accessing formal healthcare. The reasons to use traditional healers may include difficulties in accessing formal healthcare, certain beliefs about snakes and snake venom, tradition, and trust in the capacity of traditional healers.

Long-term outcomes of end-stage kidney disease for patients with lupus nephritis.

Patient outcomes in end-stage kidney disease (ESKD) secondary to lupus nephritis have not been well described. To help define this we compared dialysis and transplant outcomes of patients with ESKD due to lupus nephritis to all other causes. All patients diagnosed with ESKD who commenced renal replacement therapy in Australia and New Zealand (1963-2012) were included.

Long-term outcomes of end-stage kidney disease for patients with IgA nephropathy: A multi-centre registry study.

Background: Clinical outcomes of patients with end-stage kidney disease (ESKD) receiving renal replacement therapy (RRT) secondary to IgA nephropathy (IgAN) have not been well described.

Aim: To investigate the characteristics, treatments and outcomes of ESKD because of kidney-limited IgAN and Henoch-Schönlein purpura nephritis (HSPN) in the Australian and New Zealand RRT populations.

Methods: All ESKD patients who commenced RRT in Australia and New Zealand between 1971 and 2012 were included.

Viral RNA in the influenza vaccine may have contributed to the development of ANCA-associated vasculitis in a patient following immunisation.

A number of large studies have demonstrated influenza vaccinations to be safe and effective. However, there have been some sporadic case reports, describing a temporal association of influenza vaccination with onset or relapse of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. The nature of this association, beyond time of occurrence, remains unknown.

Rituximab versus cyclophosphamide in ANCA-associated renal vasculitis: 2-year results of a randomised trial.

Objectives: The RITUXVAS trial reported similar remission induction rates and safety between rituximab and cyclophosphamide based regimens for antineutrophil cytoplasm antibody (ANCA)-associated vasculitis at 12 months; however, immunosuppression maintenance requirements and longer-term outcomes after rituximab in ANCA-associated renal vasculitis are unknown.

Methods: Forty-four patients with newly diagnosed ANCA-associated vasculitis and renal involvement were randomised, 3:1, to glucocorticoids plus either rituximab (375 mg/m(2)/week×4) with two intravenous cyclophosphamide pulses (n=33, rituximab group), or intravenous cyclophosphamide for 3-6 months followed by azathioprine (n=11, control group).

Results: The primary end point at 24 months was a composite of death, end-stage renal disease and relapse, which occurred in 14/33 in the rituximab group (42%) and 4/11 in the control group (36%) (p=1.

Randomized trial investigating the safety and efficacy of influenza vaccination in patients with antineutrophil cytoplasmic antibody-associated vasculitis.

Aim: This study evaluated the safety and efficacy of influenza vaccination in patients with anti-neutrophil cytoplasmic antibody-associated vasculitis.

Methods: Thirty-one patients who were in remission were randomized to receive either a trivalent influenza vaccine or no vaccine. Vaccine efficacy was assessed at 28 days.
