Symptoms of pemphigus vulgaris are more severe when the lesions generalize to the entire body and secondary infections occur, which varies from person to person. Ordinary-type pemphigus is one of the more common and more serious types of pemphigus, and because of the different physical qualities of individuals, the clinical manifestations will also vary greatly. The prognosis of this type of pemphigus is the worst among pemphigus. If long-term, high-dose application of glucocorticoids and other immunosuppressants causes complications such as infection and multiple organ failure, or if the continuous development of the disease leads to massive fluid loss, hypoproteinemia, and malignant stasis, it can be life-threatening. For patients suffering from pemphigus vulgaris, it is important to consult a doctor in a timely manner and carry out standardized treatment under the guidance of the doctor to avoid further aggravation of the symptoms.
