Administration of Methylprednisolone for Prevention of Ovarian Hyper Stimulation Syndrome

2014-08-27 03:17:57 | BioPortfolio


This study is a prospective randomized clinical controlled trial to assess the efficacy of the Methylprednisolone for preventing ovarian hyper stimulation syndrome in in vitro fertilization (IVF) cycles.


Ovarian hyper stimulation syndrome is the most serious complication of ovarian stimulation which might be life threatening in the severe forms. Since there is still no definite cure for this syndrome, prevention is considered as an essential and vital issue. The objective of this study is to determine the effect of Methylprednisolone to prevent ovarian hyper stimulation syndrome in IVF cycles.

The study population comprises all infertile patients with diagnosis of polycystic ovarian syndrome which will undergo of in-vitro fertilization. The PCO subjects will be recognized based on the Rotterdam criteria inclusive the presence of least 2 signs of oligomenorrhea, hyper androgynism (clinical or laboratory), LH/FSH>2 and ovarian morphological evidences in Doppler ultrasound.

The existence of more than 20 follicles in both ovaries and E2 concentration >4000 pg/ml will be considered as the OHSS risk factors.

In this study all eligible patients will be randomly allocated into two study groups by a computerized randomization method:

Treatment group (case) will be administered 16 mg Methylprednisolone initiated from the first day of stimulation and will be tapered after the first pregnancy test (day 13 after the embryo transfer). Furthermore, these patients will receive a bolus IV dose methylprednisolone, 1g on the day of egg collection and embryo transfer.

Patients in the control group will not receive any treatment with glucocorticoids. If each group confronts with every kind of high risk signs or symptoms, they will undergo coasting or gonadotropin withdrawal or other treatment strategies.

The presence of OHSS is defined in accordance with the Golan 5 grade system and women who at least are at grade 2 of this classification (Mild) considered as OHSS cases and will experience abdominal distention and discomfort, nausea and vomiting and/or diarrhea and enlargement of ovaries(5-12cm). In Moderate forms, ultrasound evidences of ascites will be observed and severe OHSS accompany with clinical signs of ascites, hydrothorax, breathing disorders, hemoconcentration, coagulopathy and renal perfusion decrease.

Medical and Biotech [MESH] Definitions

A complication of OVULATION INDUCTION in infertility treatment. It is graded by the severity of symptoms which include OVARY enlargement, multiple OVARIAN FOLLICLES; OVARIAN CYSTS; ASCITES; and generalized EDEMA. The full-blown syndrome may lead to RENAL FAILURE, respiratory distress, and even DEATH. Increased capillary permeability is caused by the vasoactive substances, such as VASCULAR ENDOTHELIAL GROWTH FACTORS, secreted by the overly-stimulated OVARIES.

Autosomal dominant HEREDITARY CANCER SYNDROME in which a mutation most often in either BRCA1 or BRCA2 is associated with a significantly increased risk for breast and ovarian cancers.

Hereditary nonpolyposis colorectal neoplasms associated with other malignancies, more commonly of ovarian or uterine origin. When also associated with SEBACEOUS GLAND NEOPLASMS, it is called MUIR-TORRE SYNDROME.

Cessation of ovarian function after MENARCHE but before the age of 40, without or with OVARIAN FOLLICLE depletion. It is characterized by the presence of OLIGOMENORRHEA or AMENORRHEA, elevated GONADOTROPINS, and low ESTRADIOL levels. It is a state of female HYPERGONADOTROPIC HYPOGONADISM. Etiologies include genetic defects, autoimmune processes, chemotherapy, radiation, and infections.
