Follow-up lasted 4.8 (0.4, 14.1) months. The most common symptoms were abdominal pain, and submandibular gland and lacrimal gland swelling (each 20.9%). Sixty-five (75.6%) participants had multiple organ involvement, and the most frequently affected organs were the pancreas (52.3%), submandibular gland (51.2%), and lacrimal gland (34.9%). A high eosinophil count; high IgE, IgG, IgG₁, and IgG₄ concentrations; and low complement C3 and C4 concentrations were present in 18.8% (16/85), 30.0% (24/80), 72.9% (62/85), 58.3% (28/48), 89.5% (77/86), 61.2% (52/85), and 50.0% (42/84), respectively, of the participants. In addition, 64.7% (55/85) were positive for autoantibodies, and the most frequent was anti-nuclear antibody (63.5%). The proportion of CD4⁺T lymphocytes increased in 25.7% (9/35) of the participants, which was accompanied by an increase in the ratio of CD4⁺/CD8⁺T lymphocytes (22.9%, 8/35). Importantly, most participants (90.0%, 18/20) had a high proportion of regulatory T (Treg) cells. High interleukin (IL)-2, IL-6, and IL-10 concentrations were present in 50.0% (11/22), 33.3% (10/30), and 16.7% (5/30), respectively, of the participants. Substantial lymphoplasmacytic infiltration, fibrosis, IgG₄-positive plasma cell infiltration, and lymphoid follicle hyperplasia or ectopic formation were present in 79.2% (42/53), 67.9%(36/53), 35.8%(19/53) and 30.2% (16/53), respectively, of the participants. Fifty-three participants with detailed pathologic data were also further evaluated, of whom 24.5% (13/53), 3.8% (2/53), and 67.9% (36/53) had definite, probable, and possible diagnoses; and 3.8% (2/53) could not be diagnosed. Compared with baseline, the percentage of eosinophils and the IgE, IgG, and IgG₄ concentrations decreased significantly; and the complement C3 and C4 concentrations had increased significantly after 6 months of treatment (all <i>P</i><0.05). The IgG₄ concentration after 6 months of treatment negatively correlated with that of C4, and positively correlated with the baseline concentration of IgE and the IgG₄/IgG ratio. <b>Conclusion:</b> IgG₄-RDs are a group of diseases characterized by male predisposition; multiple organ involvement; a high eosinophil count; high IgE, IgG, IgG₁, and IgG₄ concentrations; and a low C3 concentration.

Thirty-three confirmed cases (myosin group) and eight healthy volunteers (healthy control group) at the Department of Rheumatology and Immunology, the First Affiliated Hospital of Kunming Medical University, from October 2016 to December 2017, were collected and analyzed. Multiple parameters of the myosin group were quantified, including creatine kinase (CK), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), complement C3, and complement C4. Disease status was evaluated using a panel of tools: myositis disease activity assessment tool-muscle (MDAAT-muscle), myositis disease activity assessment tool-whole (MDAAT-all), health assessment questionnaire (HAQ), medical outcomes study health survey short form-36 item (SF-36), hand muscle strength test (MMT-8) score, and MRI T₂ mapping of muscle (22 muscles in the pelvis and thighs) T₂ values. The results showed that in the myositis group, the measurements for CK, ESR, CRP, complement C3, and complement C4 were 457.2 (165.6, 1 229.2) IU/L, 20 (10, 42) mm/1h, 3.25 (2.38, 10.07) mg/L, 0.90 (0.83, 1.06) g/L, and 0.18 (0.14, 0.23) g/L, respectively.

Using NanoString technology, the RNA expression of 770 bone marrow immune-related markers was compared between 16 patients who had progression-free survival ≥5 years and 5 patients with progressive disease. Among the 16 patients who achieved long-term survival, 9 achieved persistent minimal residual disease (MRD) negative while the other 7 had persistent positive MRD. The functional scores of each kind of immune cells were calculated based on the expression level of characteristic genes, so as to indirectly obtained the proportion of each immune cell subset. The Mann-Whitney <i>U</i> test and the Kruskal Wallis test were used for statistical analysis. <b>Results:</b> The proportion of neutrophils was significantly higher in long-surviving MM patients than in patients with progressive disease [functional scores, 13.61 (13.33, 14.25) vs. 12.93 (12.58, 13.38); <i>Z</i>=2.31, <i>P</i>=0.021].

In all, 652 consecutive patients with ANCA-associated vasculitis were admitted to the First Medical Center of the Chinese PLA General Hospital between January 2006 and December 2022. Peripheral neuropathy occurred in 91 patients. Patients were excluded if other known causes of neuropathy were present.
