Assessment of the usefulness of macroenzyme determination in the situation of increased plasma enzyme activity in the absence of clinical symptoms

Introduction: The increased activity of serum enzymes is usually a reason of multiple, often expensive and invasive diagnostic procedures. However, there are situations in which abnormal enzyme activity persists for many months or years, and detailed studies do not confirm the existence of anatomic disease. Such is the case when enzymes form complexes with immunoglobulins on the basis of the immune antigen-antibody reaction. This phenomenon is usually benign condition, is transient and does not require treatment. Aim of study: Detection of the macroenzymes in patients with elevated serum enzyme activity. Evaluation of the relationship between the presence of macroenzymes and the age of patients, body mass index, lipid profile, chronic and autoimmune diseases. Material and methods: Macroenzymes were examined by polyethylene glycol precipitation (PEG) in 121 patients with elevated values of liver or pancreatic enzymes. Results: In the study group, a statistically significant difference was found comparing the BMI of men and women. BMI was significantly higher in men with macroenzymes (p = 0.006). It was shown that the BMI of people with serum macroenzymes is significantly higher (p = 0.049) than those without macroenzymes. A statistically significant correlation was observed between the presence of macroamylase and body weight, r = 0.33, p = 0.039. A positive correlation of triglycerides and macrogenzofacts in the serum was found. Macroamylase was observed the most frequently in the healthy group and those suffering from chronic diseases (45.83% and 42.86%). In the group of autoimmune diseases (autos) the most common was macro-GGTP (42.86%). In patients with inflammatory bowel disease, 80% of the confirmed macroenzymes in serum were macro-CK.
