A case of ovarian torsion in a patient carrier of a FSH receptor gene mutation previously affected by spontaneous ovarian hyperstimulation syndrome

Ovarian Hyperstimulation syndrome combined with hypothyroidism: a comprehensive review

Ovarian Hyperstimulation Syndrome (OHSS) is a systemic condition marked by the enlargement of the ovaries and heightened vascular permeability. And hypothyroidism (HT) emerges as a potential risk factor for OHSS occurrence. This review presented a comprehensive summary of pertinent case reports involving patients diagnosed with both HT and OHSS. Detailed exploration was conducted into their clinical presentations, diagnostic methodologies, and treatment modalities. Additionally, the review delved into potential interaction mechanisms between HT and OHSS, encompassing various aspects including hormone levels. Moreover, management strategies for mitigating the risk of OHSS in HT patients were thoroughly reviewed and the importance of monitoring thyroid function in those experiencing OHSS was emphasized. This review indicated that the association between HT and OHSS, underscoring its multifaceted complexity. It could accentuate the ongoing necessity for rigorous research and clinical refinement to deepen our comprehension of this association and to bolster diagnostic and therapeutic methodologies for optimal patient care. In conclusion, this review offered valuable insights for future research directions and clinical practices for patients afflicted with OHSS and HT.

Spontaneous ovarian hyperstimulation syndrome in a nonpregnant female patient: a case report and literature review

Spontaneous ovarian hyperstimulation syndrome (sOHSS) usually occurs in patients with a spontaneous ovulation cycle, especially in those with multiple pregnancies combined with hypothyroidism and polycystic ovary syndrome. sOHSS rarely occurs in women who are not pregnant. A 23-year-old woman with obvious abdominal distension visited our hospital. The patient was not pregnant and had not undergone controlled superovulation. Apart from abdominal distension, the patient denied any symptom of obvious incentives, abdominal pain, abnormal vaginal bleeding, or drainage. Biochemical analysis showed a high carbohydrate antigen-125 level and low total protein and albumin levels. Abdominal ultrasound and computed tomography showed a large amount of ascites and cystic uneven masses with an irregular shape in the area of the ovaries and fallopian tubes. Post-surgical histopathology indicated the diagnosis of sOHSS. Wedge resection of both ovaries was performed. Symptomatic treatment was further performed and the patient recovered well. Our findings indicate that sOHSS can occur in women who are not pregnant. Additionally, besides the follicle-stimulating hormone receptor gene mutation hypothesis, the pathogenesis of sOHSS should be further studied.

Ovarian hyperstimulation syndrome in a frozen-thawed embryo transfer pregnancy: a rare case report

Background

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of ovarian stimulation. Prevention and early recognition of OHSS are important to ensure patient safety.

Case presentation

In this case, we reported a patient who underwent controlled ovarian hyperstimulation (COH) and in vitro fertilization (IVF). All embryos were cryopreserved to reduce possible OHSS. However, OHSS still occurred after the patient had a frozen-thawed embryo transfer (FET) with hormone replacement therapy (HRT) and obtained a dichorionic diamniotic triplet pregnancy. After multifetal pregnancy reduction (MFPR) and supportive treatment, all the symptoms regressed.

Conclusions

Prompt recognition of OHSS, especially in patients who have no history of ovulation induction and fresh embryo transfer, is very important. Multiple pregnancies may lead to severe OHSS because of the high level of human chorionic gonadotropin (hCG) in the early stages. We suggest that a single embryo transfer may be necessary and beneficial for patients.

Oligosypthomatic ovarian hyperstimulation syndrome in a spontaneous uneventful pregnancy. A case report

Spontaneous hyperstimulation syndrome (spOHSS) is a rare event in pregnancies following natural conception. Only a few cases are reported in the scientific literature and result associated with massive ovarian enlargement with multiple cysts, dehydration, and fluid accumulation in the "third space". We report a novel case of spOHSS in a naturally conceived singleton pregnancy. The spOHSS was characterized by massive ovarian enlargement with multiple cysts. No dehydration and no signs of ascites were observed. The pregnancy uneventful evolved up to term.

Lifesaving dose increment of cabergoline in life-threatening spontaneous ovarian hyperstimulation syndrome resistant to all interventions

OBJECTIVE

Spontaneous ovarian hyperstimulation syndrome (SOHSS) is an extremely rare complication that deserves a multidisciplinary approach together with a thorough investigation for the correct diagnosis of the underlying pathology. The aim of this study was to present a case of severe SOHSS resistant to all interventions and to discuss the available interventions to overcome such a rare and serious clinical situation.

CASE REPORT

We report a case of severe, life-threatening spontaneous OHSS with a normal nine weeks singleton pregnancy in a 25-year-old nulliparous woman, which resulted with pregnancy termination and continuation of disease progression until the dose of cabergoline was increased to 1.5 mg/day.

CONCLUSION

This case report emphasizes that patients with life-threatening SOHSS resistant to all medical and surgical interventions may benefit from higher doses of cabergoline. Although spontaneous OHSS is extremely rare, it is potentially a life-threatening clinical entity in its severe form and needs time management and detailed examination of the underlying causes.

First mutation in the FSHR cytoplasmic tail identified in a non-pregnant woman with spontaneous ovarian hyperstimulation syndrome

Background

Spontaneous ovarian hyperstimulation syndrome (sOHSS) is a rare event occurring mostly during natural pregnancy. Among described etiologies, some activating mutations of FSH receptor (FSHR) have been identified.

Case presentation

We report hereby the case of a non-pregnant women with three episodes of sOHSS. Hormonal evaluation was normal and no pituitary adenoma was detected. However, genetic analysis identified a novel heterozygous FSHR mutation (c.1901 G > A). This R634H mutation is the first described in the cytoplasmic tail of the receptor. Functional analysis failed to reveal constitutive activity of the mutant but a decreased cAMP production in response to FSH. The weak activity of this mutant is correlated with a markedly reduced cell surface expression.

Conclusion

Pathophysiology of non gestationnal sOHSS is still ill established. The molecular characterization of this new mutant indicates that it might not be at play. Therefore, further investigations are needed to improve knowledge of the molecular mechanism of this syndrome.

Ovarian torsion and spontaneous ovarian hyperstimulation syndrome in a twin pregnancy: A case report

•

Spontaneous ovarian hyperstimulation syndrome (OHSS) can result from hyperstimulation of the follicle-stimulating hormone (FSH) receptor by FSH or other glycoprotein hormones such as chorionic gonadotrophin hormone (hCG), thyroid-stimulating hormone (TSH), and luteinizing hormone (LH); mutations of the FSH receptor gene can make these receptors abnormally sensitive to hCG, TSH, or both.

•

In patients with ovarian cysts and suspected spontaneous OHSS, it is important to determine whether hydatidiform mole, multiple pregnancie, hypothyroidism, glycoprotein-secreting adenoma or FSH receptor mutation are present.

•

Although rare, in the context of spontaneous OHSS and abdominal pain, ovarian complications such as follicular rupture, cyst hemorrhage, or ovarian torsion should always be considered.

Introduction

Ovarian hyperstimulation syndrome (OHSS) is extremely rare in spontaneous pregnancies. Spontaneous OHSS can result from glycoprotein hormones stimulating follicle-stimulating hormone receptors (FSHR).

Presentation of case

We report a twin pregnancy in which ovarian torsion and hemoperitoneum complicating OHSS were treated with left adnexectomy and aspiration. The only trigger for spontaneous OHSS in this case was high levels of chorionic gonadotropin hormone.

Discussion

Multiple pregnancy, gestational trophoblastic disease, primary hypothyroidism, thyroid-stimulating hormone/gonadotropin-secreting adenomas, and mutations of the FSHR gene may trigger spontaneous OHSS.

Conclusion

Spontaneous OHSS should be included in the differential diagnosis of acute abdomen in pregnant women; if spontaneous OHSS is diagnosed, the etiology should be determined in order to focus the treatment and avoid future complications.

Spontaneous ovarian hyperstimulation syndrome - understanding the dilemma

Ovarian hyper-stimulation syndrome (OHSS) is an uncommon identity due to variable number of causes, gestation and gestational disease being more common than thyroiditis and other causes. The role of radiology and biochemical markers are of utmost importance in not only diagnosing spontaneous ovarian hyper-stimulation syndrome (sOHSS) but also ruling out other cystic ovarian diseases and to determine the underlying aetiology and course of the disease. Understanding its pathophysiology and genetics holds the key to unravel the mysteries of this condition.
