zithromax and Abortion--Septic

The aim of this study was to determine the effect of azithromycin on LPS-induced pregnancy loss. Thirty-six pregnant female Wistar rats were divided into 4 equal groups as follows: control group, where 0.3 mL of normal saline solution was administered intravenously on day 10 of pregnancy; azithromycin group, where azithromycin was administered orally at 350 mg kg(-1) day on days 9, 10, and 11 of pregnancy; lipopolysaccharide group, where LPS was administered intravenously via the tail vein at 160 μg kg(-1) on day 10 of pregnancy; and the azithromycin + LPS group, where azithromycin was administered orally at 350 mg kg(-1) day on days 9, 10, and 11 of pregnancy and LPS was administered intravenously at 160 μg kg(-1) on day 10 of pregnancy. Blood samples were obtained from the tail vein on day 10 of the experiment. Pregnancy rates were determined. Tumor necrosis factor-alpha (TNF- α ) and interleukin (IL-10) levels were measured by ELISA. Azithromycin prevented (P < 0.05) LPS-induced pregnancy loss. Higher TNF- α and IL-10 levels were measured (P < 0.05) in the LPS and azithromycin + LPS groups, respectively. In conclusion, azithromycin may be useful in infection- or endotoxemia-dependent pregnancy loss.
