The endometriosis treatment was critical due to complications associated with current drug delivery system. The present study was conducted with aim to compare the curative effect of Vitamin D3 (VTD3) and Omega–3 (OG3) with Diphereline during the treatment of endometriosis.

In this study, endometriosis was induced in different groups containing 60 adult female rats. The rat model was categorized into 6 groups untreated and treated (Olive Oil (solvent), VTD3 (42 mcg/kg/day), OG3 (450 mg/kg/day), VTD3+OG3, Diphereline (3 mg/kg/day)). The suspension containing combination of Diphereline and supplements was injected and treated for 4 weeks to analyze the effect of supplements. The interleukin -6 (IL-6) and Tumor necrosis factor – alpha (TNFα) inflammatory responses were measured from the serum samples while endometrial implants was dissected and histopathological investigation was done.

At the end of four weeks, pathologic score decreased significantly with simultaneous measurement of inflammation score of endometriotic lesion, size of implant area, IL-6, TNFα response and compared with untreated female rat. No significant different was observed in groups undergoing treatment of VTD3, OG3 and Diphereline. The combined effect of VTD3+OG3 has similar responses with Diphereline treated endometrial implants.

treatment of VTD3 deficiency and making a change in dietary habits of high-risk population for endometriosis from adolescence may also play a preventative role in adulthood.

Ectopic pregnancy (EP) is one of the major causes of maternal mortality during the first trimester of pregnancy.

Four treatment methods for EP including single-dose methotrexate (SD-MTX), double-dose methotrexate, expectant and surgical management were considered.

In this cross-sectional study, the clinical characteristics of 365 women aged 15-44 yr who had been diagnosed with EP were reviewed from March 2017 to March 2019 in hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. Receiver operating characteristics curves were plotted to determine the cut-off points for size of ectopic mass and beta-human chorionic gonadotropin (β-hCG) that suitably discriminated between double-dose methotrexate and surgery management.

The most common site of EP was adnexa. According to the receiver operating characteristics analysis, surgery was the best plan for the women with an ectopic mass > 34.50 mm in diameter or with an initial β-hCG level > 6419 mIU/ml. The β-hCG levels in the women successfully treated with SD-MTX were significantly lower than in those with failed treatment (p = 0.02). The SD-MTX group had a higher success rate and significantly shorter duration of hospitalization, and so this was a more effective medical treatment in comparison with the DD protocol.

Surgery is proposed as the best option for the cases with large ectopic mass or high β-hCG level. SD-MTX had a higher success rate and shorter hospital stay than the DD protocol, and so was found to be an efficient and safe alternative. Further randomized clinical trials with larger sample sizes are recommended to validate the current results.
