A 31-year old woman with persistent fever for 6 weeks and unresponsive to antibiotic therapy came for rheumatologic investigation. After computed tomography (CT) studies of her neck, thorax and abdomen revealed bilateral cervical, axillary and retroperitoneal lymph node enlargements, histopathologic evaluation of the resected nodes showed features of histiocytic necrotizing lymphadenopathy suggestive of Kikuchi-Fujimoto's lymphadenopathy. Kikuchi-Fujimoto Disease (KFD) involving the retroperitoneal nodes is extremely unusual and even more challenging to diagnose when there are no early signs of extranodal involvement or abdominopelvic pain. We present a case of systemic KFD involving the cervical, axillary and retroperitoneal lymph nodes and emphasize the clinical interest to properly differentiate between the benign condition of KFD that requires no more than minimal to low dosage steroid therapy and the potentially life-threatening lupus lymphadenitis that mandates intensive immunosuppressive treatment.

Blood DNA virome associates with autoimmune diseases and COVID-19.

Aberrant immune responses to viral pathogens contribute to pathogenesis, but our understanding of pathological immune responses caused by viruses within the human virome, especially at a population scale, remains limited. We analyzed whole-genome sequencing datasets of 6,321 Japanese individuals, including patients with autoimmune diseases (psoriasis vulgaris, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), pulmonary alveolar proteinosis (PAP) or multiple sclerosis) and coronavirus disease 2019 (COVID-19), or healthy controls. We systematically quantified two constituents of the blood DNA virome, endogenous HHV-6 (eHHV-6) and anellovirus.

Kikuchi-Fujimoto disease (KFD) is a rare, self-limiting, and ultimately benign condition characterised by localised lymphadenopathy. The association of KFD with aseptic meningitis is even more uncommon. We report a case of KFD accompanied by aseptic meningitis in a 31-year-old male who initially presented with lethargy, night sweats, axillary lymphadenopathy, and oral ulcers.

Therapeutic plasma exchange (PLEX) is an adjunctive treatment for patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis and kidney involvement. Little is known about the effect of PLEX on early changes in kidney function. This post-hoc analysis of the PEXIVAS trial investigated the effects of PLEX on changes in kidney function within 12 months.

Article Synopsis
- Autoinflammatory disorders are characterized by an exaggerated response of the innate immune system, primarily involving neutrophils and macrophages, and are differentiated from connective tissue diseases by the absence of anti-nuclear antibodies.
- Many of these disorders are linked to inherited genetic mutations and tend to manifest in childhood or early adulthood, though some, like VEXAS syndrome, highlight the potential for acquired mutations in adults.
- The review focuses on the cutaneous manifestations of various acquired autoinflammatory disorders, including adult-onset Still's disease and Schnitzler syndrome, which have significant diagnostic implications.

Kikuchi-Fujimoto disease (KFD) and adult-onset Still disease (AOSD) are two rare conditions whose association poses a significant diagnostic challenge. KFD is characterized by subacute necrotizing lymphadenitis of unknown etiology, primarily affecting young adults, and often presents with fever and posterior cervical lymphadenopathy. AOSD is a systemic inflammatory disorder of unclear origin, defined by high-spiking fever, lymphadenopathy, hepatosplenomegaly, hyperferritinemia, and leukocytosis.
