This paper studied the effects of atorvastatin on experimental endometriosis in 24 female rats, comparing daily atorvastatin (10 mg/kg for 14 days) with leuprolide acetate (1 mg/kg) and saline controls after endometriosis induction. The authors assessed endometriotic focus dimensions and performed biochemical, histopathological, and immunohistochemical analyses, along with nociception testing using a hot plate model. Atorvastatin produced significant analgesic activity and significantly reduced serum high-sensitivity C-reactive protein and tumor necrosis factor-α levels, with lower histologic and immunohistochemical scores versus controls. The main caveat is that this is an animal model with short-term dosing and no explicit discussion of translation limits to humans. This paper is centrally about endometriosis — it evaluates atorvastatin’s anti-nociceptive and anti-inflammatory effects in a rat endometriosis model.

Abstract

PurposeThe purpose of this study was to examine the effects of atorvastatin in the treatment of experimental endometriosis.MethodsEndometriosis was induced in 24 female rats. 4 weeks after the procedure dimensions of the foci were recorded. Rats were divided into three groups: in Group 1 (n = 8), a daily dose of 10 mg/kg atorvastatin was given for 14 days. In the second group (n = 8), a single dose of 1 mg/kg leuprolide acetate was injected intraperitoneally. The rats in Group 3 (n = 8) were received 1 mg/kg i.p. 0.9 % NaCl. At the end of the treatment, laparotomy was performed, and the dimensions of the endometriotic foci were recorded. Biochemical, histopathological and immunohistochemical studies were performed and nociception was compared in groups.ResultsAtorvastatin treatment exhibited significant analgesic activity in hot plate model (P = 0.022). The serum hs-CRP and tumor necrosis TNF-α levels were similar between the Group 2 and Group 3 (P > 0.05); however atorvastatin caused significant decrease in both serum markers. The histological and immunohistochemical scores were also found to be markedly lower in Group 1 and Group 2 (P < 0.05).ConclusionAtorvastatin treatment may have a therapeutic potential in the treatment of endometriosis through its anti-inflammatory and anti-nociceptive properties.

Abstract

Purpose The purpose of this study was to examine the effects of atorvastatin in the treatment of experimental endometriosis.

Methods

Endometriosis was induced in 24 female rats. 4 weeks after the procedure dimensions of the foci were recorded. Rats were divided into three groups: in Group 1 (n = 8), a daily dose of 10 mg/kg atorvastatin was given for 14 days. In the second group (n = 8), a single dose of 1 mg/kg leuprolide acetate was injected intraperitoneally. The rats in Group 3 (n = 8) were received 1 mg/kg i.p. 0.9 % NaCl. At the end of the treatment, laparotomy was performed, and the dimensions of the endometriotic foci were recorded. Biochemical, histopathological and immunohistochemical studies were performed and nociception was compared in groups.

Results

Atorvastatin treatment exhibited significant analgesic activity in hot plate model (P = 0.022). The serum hs-CRP and tumor necrosis TNF-α levels were similar between the Group 2 and Group 3 (P > 0.05); however atorvastatin caused significant decrease in both serum markers. The histological and immunohistochemical scores were also found to be markedly lower in Group 1 and Group 2 (P < 0.05).

Conclusion

Atorvastatin treatment may have a therapeutic potential in the treatment of endometriosis through its anti-inflammatory and anti-nociceptive properties. Similar content being viewed by others
