Objective: To detect the variations in peripheral blood levels of autoantibodies, immunoglobulilns and complements in patients with non-lactational mastitis and investigate whether non-lactational mastitis is an autoimmune disease with immune dysfunction.
Methods: Seven-eight patients with non-lactational mastitis treated in our hospital between September 2013 and May 2015 and 88 healthy women (control) were examined for peripheral blood levels of antinuclear antibody (ANA), anti-histone antibody (AHA), immunoglobulins (IgA, IgM, and IgG) and complements (C3, C4, and total complements).
Results: s Of the 78 patients with non-lactational mastitis, 50 (64.10%) were positive of ANA showing mainly the granular and cytoplasmic granular fluorescence patterns, and the positivity rate was significantly higher than that in the control group (P<0.000). Twenty-eight (36.00%) of the patients were positive of AHA, a rate significantly higher than that in the control group (P<0.000). The levels of IgA, IgM, C4, and total complements levels were all significantly elevated in the patients compared with those in the control group (P<0.05).
Conclusion: Patients with non-lactational mastitis have abnormal changes in peripheral blood levels of immunoglobulins and complements with high positivity rates for ANA and AHA, indicating that non-lactational mastitis is an autoimmune disease with immune dysfunction.

Discrimination Model Construction for Non-Lactational Mastitis and Breast Cancer Based on Imaging Features.

The clinical presentation of non-lactational mastitis (NLM) shares similarities with some symptoms and examination results of breast cancer (BC), which can lead to misdiagnosis or delayed treatment. Current studies on breast lesions mostly focus on the diagnostic performance of a single imaging technique. This study aims to construct a discrimination diagnostic model for NLM and BC based on such imaging features as ultrasound and magnetic resonance imaging (MRI) and to validate the application value of the model, assisting clinicians in improving disease diagnosis and refining medical decisions.

There is no unified and effective standard treatment plan for this disease at present. In addition to breast cancer, non-lactational mastitis is also becoming a presenting complaint in an increasing number of outpatients at the authors' clinic.

Breast abscesses are still a common cause of morbidity among lactational females. Over the years, there has been an increase in the incidence of non-lactational breast abscesses and a decrease in lactational breast abscesses. The management could be the use of the conventional method of surgical incision and drainage or the newer techniques of needle aspiration or suction drain or catheter in addition to the administration of antibiotics.

Background: Breast abscess is a prevalent cause of morbidity in women occurring in 0.4% to 11% of patients after mastitis. The majority are benign, but worrisome etiologies such as inflammatory cancer and concomitant immune-compromising diseases should be addressed when a non-lactating patient presents with a breast abscess.
