Summary

Serum protein changes in tuberculosis patients show decreased total proteins and albumin, with increased globulins, particularly gamma globulin. The albumin/alpha-2 ratio decrease is not diagnostic of disease activity.

Area of Science:

  • Clinical Chemistry
  • Immunology
  • Pulmonology

Background:

  • Serum protein electrophoresis is a valuable diagnostic tool.
  • Pulmonary tuberculosis (TB) is a significant global health concern.
  • Understanding protein alterations in TB can aid diagnosis and monitoring.

Purpose of the Study:

  • To investigate serum protein changes in patients with pulmonary tuberculosis.
  • To compare protein profiles between TB patients and healthy controls.
  • To evaluate the diagnostic utility of the albumin/alpha-2 ratio in TB.

Main Methods:

  • Serum electrophoresis was performed on 31 pulmonary tuberculosis patients and 62 controls.
  • Total protein, albumin, and globulin fractions (including gamma and alpha-2) were quantified.
  • The albumin/alpha-2 ratio was calculated and analyzed.

Main Results:

  • Tuberculosis patients exhibited significantly lower total proteins and albumin compared to controls.
  • A notable increase in globulin levels, primarily the gamma globulin fraction, was observed in TB patients.
  • The albumin/alpha-2 ratio decreased significantly in sputum-positive TB cases, mainly due to reduced albumin, not elevated alpha-2 globulin.

Conclusions:

  • Pulmonary tuberculosis significantly alters serum protein electrophoresis patterns.
  • The observed changes include decreased albumin and increased gamma globulin.
  • The decrease in the albumin/alpha-2 ratio is not a reliable diagnostic marker for active tuberculosis.
