Serum Protein Electrophoresis Patterns in Patients with Osteoarticular Tuberculosis

Tuberculosis (TB) is a leading cause of infectious disease deaths in India. It is also one of the most challenging diseases to diagnose and treat effectively. TB can occur both in the lungs and in extrapulmonary locations through hematogenous spread. Osteoarticular TB is a type of extrapulmonary characterized by atypical presentation. If diagnosed early, it can be treated effectively with reduced risk of mortality.

At Nalanda medical college and hospital, an 18-month prospective research was undertaken. The study included a total of 120 patients with osteoarticular TB. Serum electrophoresis of blood samples was performed at baseline, 2 months, and 4 months following antitubercular medication administration. The fractions of albumin, α1, α2, β, and γ globulins were estimated and compared with the baseline value.

It was observed that as the disease progressed and became more chronic, there was a decrease in albumin and an increase in α1, α2, β, and γ globulin percentages of serum proteins. Upon follow-up, the serum electrophoresis revealed that these values observed during baseline could be reversed by the administration of antitubercular drugs.

This study suggests that analyzing serum protein fractions could be a cost-effective strategy to determine the presence of osteoarticular TB and also aid in initiating antitubercular treatment.
