Cystic fibrosis (CF) clinicians may see patients who have difficult-to-manage symptoms that do not have a clear CF-related etiology, such as unusual gastrointestinal (GI) complaints, vasculitis, or arthritis. Alterations in immunity, inflammation and intraluminal dysbiosis create a milieu that may lead to autoimmunity, and the CF transmembrane regulator protein may have a direct role as well. While autoantibodies and other autoimmune markers may develop, these may or may not lead to organ involvement, therefore they are helpful but not sufficient to establish an autoimmune diagnosis...

BACKGROUND: Takayasu arteritis (TAK) is an autoimmune large vessel vasculitis that affects the aorta and its major branches, eventually leading to the development of aortic aneurysm and vascular stenosis or occlusion. This retrospective and prospective study aimed to investigate whether the gut dysbiosis exists in patients with TAK and to identify specific gut microorganisms related to aortic aneurysm formation/progression in TAK. METHODS: We analysed the faecal microbiome of 76 patients with TAK and 56 healthy controls (HCs) using 16S ribosomal RNA sequencing...

OBJECTIVES: To investigate the association between decreased serum IgG levels caused by remission-induction immunosuppressive therapy of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) and the development of severe infections. METHODS: We conducted a retrospective cohort study of patients with new-onset or severe relapsing AAV enrolled in the J-CANVAS registry, which was established at 24 referral sites in Japan. The minimum serum IgG levels up to 24 weeks and the incidence of severe infection up to 48 weeks after treatment initiation were evaluated...

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...

Primary hemophagocytic lympho-histiocytosis (HLH) is a hyperinflammatory syndrome with devastating consequences. Multisystem involvement is a hallmark of HLH; however, HLH may rarely present with signs and symptoms isolated to the central nervous system (CNS). Within the brain, HLH can mimic demyelination, chronic infection, or vasculitis, leading to a diagnostic delay of months to years. We describe here a 7-year-old boy who presented with a history of prolonged fever and multiple focal neurologic deficits, which were being treated as CNS tuberculosis at the referring hospital...

Behçet disease (BD) is a chronic systemic vasculitis that is clinically characterized by recurrent oral ulcers, genital ulcers, uveitis, and skin lesions. Here, we conducted bulk RNA-seq of skin samples from 4 BD patients and 4 normal controls (NCs). A total of 260 differentially expressed genes (DEGs), including 99 upregulated and 161 downregulated genes, were detected in the skin lesions of BD patients compared to NCs. These DEGs were mainly enriched in the following biological processes: the activation and migration of immune cells, the release of proinflammatory factors, and the IFN-γ signaling pathway...

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...

A 61-year-old man with no previous record of autoimmune disease developed fever, polyarthralgia, purpura, and urticaria-like rash 2 weeks after the first dose of the Moderna mRNA-1273 vaccine, and symptoms deteriorated following the second dose. He presented reduced erythrocyte and platelet counts, hyperferritinemia, high sIL-2R levels, and severe hypocomplementemia. We diagnosed hypocomplementemic urticarial vasculitis (HUVS), and his symptoms as well as laboratory findings improved following treatment with mPSL 1000 mg/day for 3 days and PSL 40 mg/day...

Kawasaki disease is a generalized systemic vasculitis that affects blood vessels throughout the body. The aetiology of Kawasaki disease is still unknown but is thought to be related to the combined effects of the immune response, genetic susceptibility, and infections including COVID-19. In this case report, we present a seven months old male infant who presented to us with fever, swollen lips, ulcers in the mouth, enlarged tonsils, strawberry tongue, conjunctivitis and generalised non-blanchable maculopapular rash...

Eosinophilic granulomatosis with polyangiitis (EGPA) is systemic vasculitis caused by eosinophilia affecting small to medium-sized blood vessels, which damages the organs. Antineutrophil cytoplasmic antibody-associated vasculitis EGPA treatment guidelines added anti-interleukin-5 antibody mepolizumab to the standard treatment protocol for active-non-severe EGPA based on the MIRRA study. Nevertheless, the role of mepolizumab in treating patients with active severe EGPA has not been established. We treated a patient with EGPA complicated with small intestine perforation using steroid pulse intravenous, high-dose glucocorticoids, intravenous high-dose immunoglobulin therapy, and mepolizumab without immunosuppression agents; the patient went into remission, suggesting that mepolizumab is an effective therapeutic agent that could lead to remission in severe EGPA...

Anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) can be associated with a high burden of morbidity and mortality in an ageing population. It is increasingly recognised that individualised management is needed. Few studies have looked specifically at frailty related outcomes in AAV and a gap remains in understanding the application of frailty assessment tools in these patients. We carried out a single centre, cohort study between 2017 to 2022. Forty-one patients who had newly diagnosed or relapsing AAV and aged ≥65 years were included...

Kawasaki disease (KD), also known as mucocutaneous lymph node syndrome, is a systemic acute vasculitis belonging to autoimmune disease. Up to now, the specific pathogenesis of this disease remains unclear, and it may involve various factors such as immune response, inflammatory response, and vascular endothelial injury caused by the activation of the nuclear factor-kappa B (NF-κB) signaling pathway. In particular, children with KD and cardiac injury tend to have a poor prognosis, and researchers hope to explore the specific pathogenesis of cardiac injury in KD to provide new options for clinical diagnosis and treatment and reduce the incidence rate of this disorder...

Kawasaki disease (KD) is a febrile disease mainly observed in children aged <5 years, with medium- and small-vessel vasculitis as the main lesion. Although KD has been reported for more than 50 years and great progress has been made in the etiology and pathology of KD in recent years, there is still a lack of specific indicators for the early diagnosis of KD, especially with more difficulties in the diagnosis of incomplete Kawasaki disease (IKD). At present, there are no clear diagnostic criteria for IKD, which leads to the failure of the timely identification and standardized treatment of IKD in clinical practice and even induce the development of coronary artery lesion...

BACKGROUND: The objectives were to define the distribution of rheumatic diseases in patients with erythrocyte sedimentation rate (ESR) ≥ 100 mm/h and to find variables that can differentiate main study groups from others. METHODS: Charts of patients admitted with ESR ≥ 100 mm/h between 2015 and 2020 were reviewed. Patients were divided into four diagnostic groups based on etiology: infection (without a rheumatic diagnosis), oncologic (without a rheumatic diagnosis), rheumatic, and no definitive diagnosis...
