Department of Molecular Genetics, Wakayama Medical University, Wakayama, Japan.
Background: Biomarkers that predict disease activity and prognosis should be established for neuromyelitis optica spectrum disorders (NMOSD). In this study, we investigated the association between complement factors and the prognosis of NMOSD.
Methods: We validated laboratory parameters as potential prognostic factors in 34 patients with NMOSD (31 females and 3 males) whose serum was collected at the time of recurrence and who were subsequently followed-up for 3 years without the use of biologics.
Challenges for complement functional assays in the clinical laboratory: From test validation to clinical interpretation.

Complement functional assays are essential first-tier tests for a gamut of disorders spanning from inborn errors of the immune system which lead to recurrent severe infections, to angioedema attacks, presentation of autoimmune disease, thrombotic microangiopathies and rare kidney disorders. These assays evaluate the activity of the three complement pathways and specific complement components, which helps in differential diagnosis and monitoring disease progression. The rising use of complement inhibitors for treating complement-mediated thrombotic microangiopathies has heightened the demand for personalized treatment plans and laboratory assessment of complement blockage.

Background: Fibromyalgia (FM) is a disease characterized by chronic widespread pain concomitant with various symptoms such as fatigue and anxiety. Although chronic inflammation has been implicated in the immunological abnormalities of FM, there are few human studies on complement and immunoglobulins. In this study, we investigated the immunological characteristics of FM patients and the association between their clinical symptoms and immunological indices, including complement and immunoglobulins.

Methods: The retrospective study cohort comprised 40 patients diagnosed with first-episode SCZ (SCZ group) and 40 healthy individuals (control group). Quantitative analyses were conducted on five complement factors, namely complement component 1 (C1), C2, C3, C4, and the 50% hemolytic complement (CH50).

Objective: To explore the therapeutic mechanism of maggot for psoriasis-like lesions in mice from the perspective of immune stress and complement activation regulation.
Methods: Thirty-six male C57BL/6 mice were randomly divided into control group, model group, maggot (1.25%, 2.
