One of the most serious complications of assisted reproduction techniques is ovarian hyperstimulation syndrome (OHSS). OHSS not only increases morbidity and mortality in IFV cycles, but also causes significant other problems, as cancelled in vitro fertilization (IVF) cycles, prolonged hospitalization, causing emotional and sociofinancial consequences. Several treatments for OHSS have been proposed and among these Cabergoline (Cb2). Despite the above-mentioned beneficial effect, Cb2 has not been widely used in everyday's clinical practice. With our study, we try to review all studies with strong evidence examining Cb2 use for OHSS prevention.
[Show abstract][Hide abstract] ABSTRACT: Background: OHSS is a dangerous and potentially life-threatening condition for which many researchers look for new ways to treat. Aim: To determine the effectiveness of prophylactic cabergoline administration on prolactine levels in patients with high risk for ovarian hyperstimulation syndrome (OHSS). Material and Methods: 163 in vitro fertilisation (IVF) patients with high risk for OHSS were enrolled in the study. The criteria for inclusion were more than 15 oocytes retrieved at oocyte pick up. A standard antagonist protocol was used for ovulation induction. Cabergoline treatments (0.5 mg/day) were started on the day of oocyte retrieval and continued for eight days. Prolactine levels were measured at the day of oocyte retrieval and the 9th day after the oocyte retrieval. Results: Of the 163 patients, 26 (15.9%) had OHSS. Prolactine levels on the day of oocyte retrieval were 44.22 ± 24.78 ng/mL and 37.6 ± 22.5 ng/mL in patients with OHSS and without OHSS, respectively (P > 0.05). In contrary prolactine levels were significantly higher in patients with OHSS patients (3.9 ± 5.07 ng/mL) than in patients without OHSS (2.1 ± 2.92 ng/mL) at the 9th day after oocyte retrieval (P < 0.05). Conclusion: Prolactine levels were higher in patients with OHSS than without OHSS who were treated with cabergoline for the prevention of OHSS.

"Another notable result of our study was the fact that the introduction of Cabergoline treatment did not lead to a significant reduction in recovery times from severe OHSS. Recently, it has been suggested that the use of dopamine agonists appeared to be effective for the prevention of OHSS, but was less effective for the treatment of OHSS [27,28]. We, however, present only non-randomized data. "
[Show abstract][Hide abstract] ABSTRACT: Background
To evaluate predictive factors for recovery time from severe ovarian hyperstimulation syndrome (OHSS).
In a retrospective cohort study, 201 women who were hospitalized for severe OHSS were included. Patients with recurrent OHSS were excluded. All the patients received standardized treatment including intravenous hydration, plasma volume expansion, human albumin, furosemid, subcutaneous heparin, and paracentesis if necessary. The main outcome parameter was recovery time from OHSS. Recovery was defined if a morning hematocrit <40%, rebalance of electrolytes, and serum creatinine <1 mg/dL were reached during the standardized therapy and the patient had not suffered from abdominal pain and discomfort at least for one day without any OHSS-specific infusions or medications.
Pregnant patients (n = 80, 39.8%) revealed a longer median duration until recovery than non-pregnant patients (n = 121, 60.2%; 10 days, IQR 7-13, vs. 8 days, IQR 6-10, respectively; p = 0.001). In a generalized linear model, presence of polycystic ovary syndrome before controlled ovarian hyperstimulation (beta = 0.3342 +/- 0.1335, p = 0.012) and use of hCG for ovulation induction (beta = 0.222 +/- 0.1389, p = 0.048) were associated with a longer recovery time in pregnant patients. In non-pregnant patients, none of the tested factors was associated with recovery time.
Pregnant patients with severe OHSS needed a significantly longer recovery time than non-pregnant patients. In pregnant patients, presence of polycystic ovary syndrome and ovulation induction with hCG were associated with longer recovery times.
"Cabergoline is an ergot derived-dopamine D2-like receptor agonist that has high affinity for D2, D3, and 5-HT2B receptors (Ki = 0.7, 1.5, and 1.2, respectively) . Its property of having high affinity for D2 receptor is beneficial for dopamine replacement therapy of Parkinson disease (PD) , hyperprolactinemia , ovarian hyperstimulation syndrome , Cushing's disease , and restless legs syndrome . Because cabergoline has a longer elimination half-life (63 to 109 h) compared with other D2-like receptor agonists, both a long-lasting clinical effect following single-dose administration ,  and an improvement in the quality of life of patients with chronic diseases are expected. "
[Show abstract][Hide abstract] ABSTRACT: Several lines of evidence demonstrate that oxidative stress is involved in the pathogenesis of neurodegenerative diseases, including Parkinson's disease. Potent antioxidants may therefore be effective in the treatment of such diseases. Cabergoline, a dopamine D2 receptor agonist and antiparkinson drug, has been studied using several cell types including mesencephalic neurons, and is recognized as a potent radical scavenger. Here, we examined whether cabergoline exerts neuroprotective effects against oxidative stress through a receptor-mediated mechanism in cultured cortical neurons. We found that neuronal death induced by H2O2 exposure was inhibited by pretreatment with cabergoline, while this protective effect was eliminated in the presence of a dopamine D2 receptor inhibitor, spiperone. Activation of ERK1/2 by H2O2 was suppressed by cabergoline, and an ERK signaling pathway inhibitor, U0126, similarly protected cortical neurons from cell death. This suggested the ERK signaling pathway has a critical role in cabergoline-mediated neuroprotection. Furthermore, increased extracellular levels of glutamate induced by H2O2, which might contribute to ERK activation, were reduced by cabergoline, while inhibitors for NMDA receptor or L-type Ca2+ channel demonstrated a survival effect against H2O2. Interestingly, we found that cabergoline increased expression levels of glutamate transporters such as EAAC1. Taken together, these results suggest that cabergoline has a protective effect on cortical neurons via a receptor-mediated mechanism including repression of ERK1/2 activation and extracellular glutamate accumulation induced by H2O2.
