Association of brucellosis with renal tubular and glomerular damage in children in Turkey

الملخص EN

Brucellosis is a multisystem disease that may present with a broad spectrum of clinical manifestations.

Until now, no studies have been performed on renal tubular disorders in patients with brucellosis.

The present study aims to investigate renal tubular disorders in patients with brucellosis.

This prospective case–control study includes a total of 31 brucellosis patients (Group 1) and 30 healthy controls (Group 2) matched for age and sex.

Renal tubular functions of children who were diagnosed as having brucellosis in outpatient pediatric clinics were evaluated.

First-morning urine samples were collected from Group 1 and Group 2 at the same time.

Urea, creatinine, potassium, sodium, and phosphorus were determined in serum and urine by an autoanalyzer.

Tubular reabsorption and excretion of urine electrolytes were calculated using the related formulas.

Patients with brucellosis had significantly lower levels of tubular reabsorption of phosphorus and serum phosphorus than those of the control group.

Furthermore, urine sodium and serum potassium levels and fractionated sodium excretion of brucellosis patients were significantly higher than healthy control group.

Estimated glomerular filtration rate was remarkably higher in the patient group (P < 0.001).We concluded that tubular and glomerular functional parameters demonstrate deterioration in patients with brucellosis compared to those in healthy participants
