Immunophenotypic profiles and inflammatory markers in Premature Ovarian Insufficiency.

Premature Ovarian Insufficiency (POI), also known as Premature Ovarian Failure (POF), is a heterogeneous disorder characterized by the cessation of ovarian function before age 40. Clinical symptoms include menstrual disorders: amenorrhea/oligomenorrhea or symptoms of estrogen deficiency. This review aims to provide the most important summary of the immunophenotypic profile of premature ovarian failure syndrome, along with a review of the latest reports on the usefulness of inflammatory markers. The inflammatory microenvironment in POI applies to many levels. Concomitants of autoimmune ovarian inflammation and impaired cellular immune response may be a picture of impaired regulation in autoimmune ovarian disease. The serum concentration of pro-inflammatory cytokines, like IL-6, IL-8, IL-17, tumor necrosis factor α (TNF-α), and interferon-gamma (IFN-γ), tend to increase, whereas levels of the anti-inflammatory cytokine, IL-10, tend to decrease. In our review, we focus on whether the measured immunological parameters could help in the diagnosis and prognosis of the syndrome. Among the inflammatory markers, neutrophil-to-lymphocyte ratio (NLR) is noteworthy, as it is decreased in patients with POI. It is important to stress that besides case series, we need properly powered studies with randomization to answer which treatment is effective, and how to deal with concurrent autoimmunity. In this review, we emphasize the importance of the premature ovarian failure syndrome immunoprofile for a proper understanding of the complexity of this syndrome, potential diagnostic points, and therapeutic targets.

A systematic review on idiopathic intracranial hypertension comorbid with polycystic ovarian syndrome and its consequences.

BACKGROUND: A few publications have examined the frequency and medical implications of individuals with idiopathic intracranial hypertension (IIH) and polycystic ovarian syndrome (PCOS), but the findings have been inconclusive. IIH and PCOS both mainly affect obese women of reproductive age and have an impact on women's health at various levels. The aim of this systematic review was to compare the prevalence and association between comorbid IIH and PCOS, and their effect on such aspects as metabolism, abnormalities in hormone levels, and reproduction. METHODS: The criterion for inclusion was a research study of patients suffering from both syndromes. We excluded review articles, case reports, and papers with an inappropriate study design, patient population or outcomes. Electronic databases PubMed, Scopus, Web of Science and gray literature were searched to retrieve studies published from inception to June 10, 2023. The risk of bias assessment was conducted utilizing Covidence software and by discussion between co-authors. RESULTS: After applying our inclusion/exclusion criteria, we consolidated the initial pool to a final selection of 9 articles, and 2185 patients with comorbidity of these two conditions. The prevalence of PCOS among patients with IIH was observed, with incidence rates ranging from 15.5% to 57%, which is up to 8 times greater, than the 4-10% prevalence of PCOS in the general population. These data may be valuable in clinical practice for both neurologists and gynecologists. DISCUSSION: PCOS associated with obesity facilitates concurrence of IIH. The diagnosis of concurrence of IIH and PCOS may have significant clinical implications for patients due to the accompanying hormonal disorders, obesity-related consequences, and fertility issues. Other No systematic review was found. We have registered the study in PROSPERO (International prospective register of systematic reviews), and the registration number is CRD42023437485.

Rare Clinical Presentation of Postmenopausal Endometriosis: A New Perspective.

Endometriosis affects 2-5 % of postmenopausal women with menopause hormone therapy and is less common in women without treatment with exogenous estrogen or tamoxifen. Postmenopausal endometriosis has more unknown aspects in its pathogenesis and clinical manifestation than in the case of premenopausal patients. The aim of this review was to summarize the clinical presentation of rare cases of endometriosis, including deep infiltrating (DIE) and extragenital endometriosis, in women. The symptoms of endometriosis in the post-reproductive age are more heterogeneous than in women of childbearing age, often resembling symptoms of gastrointestinal tumors or urinary tract diseases. We summarize cases of endometriosis of the intestines, liver, pancreas, and stomach, as well as endometriosis of the urinary tract and skin, with non-gynecological manifestations. We also describe the pathogenesis of endometrial tissue activity in the context of reduced estrogen levels after menopause, which is also not clear, and demands more molecular and genetic studies. NAD+-dependent deacetylases called Sirtuins are metabolic sensors for maintaining body homeostasis. In the context of endometriosis, Sirtuins are being studied for their potential role in modulating inflammation, cell proliferation, and sex hormone sensitivity, but their role in postmenopausal endometriosis is not well researched. Treatment in postmenopausal women includes mostly for now surgery, depending on the location of the lesion, and aromatase inhibitors. The complete genetic and epigenetic profile in women post-reproductive age is needed to propose target therapy, especially in severe cases such as endometriosis that is deeply infiltrating and located outside the pelvis.

A Rare Case of a Primary Leiomyoma of the Clivus in an Immunocompetent Patient and a Review of the Literature Regarding Clival Lesions.

Leiomyomas are common lesions that are usually located in the genitourinary and gastrointestinal tracts. Primary leiomyomas at the skull base are uncommon. They are composed of well-differentiated smooth muscle cells without cellular atypia. The diagnosis of a leiomyoma has to be confirmed by immunohistochemistry. The tumor tissue is immunoreactive for SMA, S100 and cytokeratin. Leiomyomas mainly occur in immunocompromised patients. Most tumor tissues are positive for EBV. The presented case is that of a 56-year-old immunocompetent woman with a tumor on the clivus. The radiological images suggested chordoma or fibrous dysplasia. Transnasal transsphenoidal surgery was performed. The tumor tissue consisted of well-differentiated smooth muscle cells with elongated nuclei. Immunohistochemistry revealed a positive reaction for desmin, SMA and h-Caldesmon and a negative reaction for S100, beta-catenin, PGR and Ki67. The leiomyoma diagnosis was subsequently established. To the best of our knowledge, the case of a primary leiomyoma on the clivus of an immunocompetent patient is the first to be described. We also extensively reviewed the literature on the immunohistopathological and radiological differential diagnosis of clival lesions.

The Genetic Backdrop of Hypogonadotropic Hypogonadism.

The pituitary is an organ of dual provenance: the anterior lobe is epithelial in origin, whereas the posterior lobe derives from the neural ectoderm. The pituitary gland is a pivotal element of the axis regulating reproductive function in mammals. It collects signals from the hypothalamus, and by secreting gonadotropins (FSH and LH) it stimulates the ovary into cyclic activity resulting in a menstrual cycle and in ovulation. Pituitary organogenesis is comprised of three main stages controlled by different signaling molecules: first, the initiation of pituitary organogenesis and subsequent formation of Rathke's pouch; second, the migration of Rathke's pouch cells and their proliferation; and third, lineage determination and cellular differentiation. Any disruption of this sequence, e.g., gene mutation, can lead to numerous developmental disorders. Gene mutations contributing to disordered pituitary development can themselves be classified: mutations affecting transcriptional determinants of pituitary development, mutations related to gonadotropin deficiency, mutations concerning the beta subunit of FSH and LH, and mutations in the DAX-1 gene as a cause of adrenal hypoplasia and disturbed responsiveness of the pituitary to GnRH. All these mutations lead to disruption in the hypothalamic-pituitary-ovarian axis and contribute to the development of primary amenorrhea.
