Montelukast as an Add-On Drug in Induced Azotemia in Humans Following Gastroenteritis

Gastroenteritis, as a rare and heterogeneous condition, is characterized by patchy or diffuse infiltration of gastrointestinal tissue. Induced azotemia in humans following gastroenteritis has been evaluated in some studies.

The aim of the present study was to evaluate the effect of montelukast on induced azotemia in humans following gastroenteritis.

This study examined children with gastroenteritis with moderate dehydration and more than 3 years of age. The cases had a glomerular filtration rate (GFR) of less than 90 and were evaluated in 2 groups of control (n = 20) and intervention (n = 20). Montelukast (5-mg tablets) was given to patients in the intervention group for 5 days. Normal saline at a rate of 20 cc/kg was given to both groups within 20 minutes until clinical symptoms improved. Finally, the improvement of renal function was evaluated and compared between the 2 groups using SPSS.

Out of 40 evaluated patients, the mean age of the control and intervention groups was 5.52 and 5.15 years, respectively. Also, 13 cases (65.0%) in the control group and 9 cases (45.0%) in the control group were males. The mean creatinine (Cr) was significantly reduced after treatment in the intervention group (P = 0.001). Also, the mean GFR after treatment was significantly higher in the intervention group (P = 0.001), and GFR improvement duration was significantly lower in the intervention group (P = 0.002).

Montelukast as an add-on drug was effective in reducing the time of GFR enhancement; thus, we can consider it as an add-on drug in azotemia.
