    Antinuclear factor (ANF) was found in 30% of patients with mental depression. This ANF-positive depression may represent a distinct psychiatric condition, often more treatment-resistant than typical depression.

    Area of Science:

    • Psychiatry
    • Immunology
    • Clinical Medicine

    Background:

    • Mental depression is a common psychiatric disorder.
    • Antinuclear factor (ANF) is an autoantibody.
    • The association between ANF and depression is not well-established.

    Purpose of the Study:

    • To investigate the prevalence of ANF in patients with mental depression.
    • To characterize the clinical features of ANF-positive depression.
    • To determine if ANF-positive depression is a distinct clinical entity.

    Main Methods:

    • Serum samples were collected from 53 newly admitted psychiatric patients diagnosed with mental depression.
    • Antinuclear factor (ANF) was detected in these serum samples.
    • Clinical characteristics and treatment response were assessed for all patients.

    Main Results:

    • Antinuclear factor (ANF) was detected in approximately 30% of the studied patients.
    • ANF-positive depression cases showed clinical similarities to manic-depressive psychosis.
    • ANF-positive depression appeared to be more resistant to standard psychiatric treatments.

    Conclusions:

    • The presence of ANF in a significant subset of depressed patients suggests a potential biological marker.
    • ANF-positive depression exhibits distinct clinical features and treatment resistance.
    • Further research is warranted to confirm ANF-positive depression as a unique disease entity.
