RESUMO
Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder among reproductive-age women. As a leading cause of anovulatory infertility, it complicates fertility treatments, including in vitro fertilization. The widely accepted 2003 Rotterdam diagnostic criteria for PCOS include sub-phenotypes based on variations in androgen excess, ovulatory dysfunction, and polycystic ovarian morphology. In this systematic review, we examined the impacts of inositol and vitamin D on fertility in PCOS. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, we used relevant keywords to comprehensively search databases including PubMed, Google Scholar, and MDPI. From an initial pool of 345 articles, 10 met the inclusion criteria. The articles suggest that vitamin D and inositol, particularly myo-inositol and D-chiro-inositol, may represent therapeutic options for PCOS. Vitamin D influences ovarian follicular development, glucose regulation, and insulin sensitivity. When combined with metformin therapy, it is associated with improved menstrual regularity and ovulation. Inositol is crucial for cellular signaling, energy metabolism, glucose regulation, and fertility. This systematic review underscores the importance of investigating inositol and vitamin D within a PCOS management strategy, given the disorder's prevalence and impacts on fertility and metabolic health. Although these agents show promise, additional research could clarify their mechanisms of action and therapeutic benefits. This review emphasizes the need for exploration of effective treatments to improve the quality of life among individuals with PCOS. Inositol and vitamin D represent potential options, but more studies are required to elucidate their roles in the management of this condition.
RESUMO
Inflammatory bowel disease (IBD) is a group of chronic disorders, including Crohn's disease (CD) and ulcerative colitis (UC), that contribute to inflammation of the gastrointestinal tract, manifesting as bloody diarrhea, fecal urgency, bloating, cramping, and weight loss. IBD manifests as an exacerbation of these symptoms, which medications with high side effect profiles can manage; consequently, many novel therapies, including biologics such as ustekinumab and vedolizumab, have been developed over the years. This systematic review aims to assess the safety and efficacy of ustekinumab and vedolizumab in treating inflammatory bowel disease based on a comprehensive analysis of relevant studies. A thorough literature search was conducted to identify randomized controlled trials, post hoc analyses, case reports, observational cohorts, and meta-analyses involving ustekinumab and vedolizumab as treatment in IBD patients. The selected studies were critically evaluated for their methodology, patient characteristics, and outcomes. The analysis involved twelve distinct studies investigating the impact of ustekinumab and vedolizumab on individuals afflicted with inflammatory bowel disease (IBD). The findings revealed a notable trend: ustekinumab displayed a propensity for yielding higher rates of clinical remission in patients with ulcerative colitis (UC). Moreover, one study underscored substantial reductions in endoscopic disease activity in patients with Crohn's disease (CD) who were on ustekinumab. Similarly, ustekinumab exhibited promising outcomes in CD patients, including swift ultrasound responses and the achievement of transmural remission, particularly among those who were new to biologic treatments. In line with this, vedolizumab demonstrated early and considerable symptomatic improvements when used to treat both UC and CD patients. While both biologics showed promising results in inducing and maintaining remission, cautious monitoring is warranted due to the potential adverse events observed in some cases. Further research with larger sample sizes and longer follow-up periods is needed to establish a comprehensive understanding of the medications' effects on IBD patients.
