The recognized role of Anti-Müllerian hormone (AMH) as a marker for women's biological age and ovarian reserve prompts debate on its efficacy in predicting oocyte quality during IVF/ICSI. Recent findings challenging this view compelled us to conduct this study to examine the correlation between AMH levels and quantity/quality of oocytes in IVF/ICSI procedures.

The data were collected retrospectively from the medical records of 320 women between 25-42 years old. The included patients were divided into two groups: the high AMH group (>1.1 ng/ml) and the low AMH (=<1.1 ng/ml) group. The high AMH group comprised 213 patients, while the low AMH group consisted of 107 patients. Spearman's correlation coefficient and Multinomial logistic regression were computed to assess the relationships between different variables.

Significant positive correlations were detected between AMH level and the number of aspirated follicles (rho=0.741, p<0.001), retrieved oocytes (rho=0.659, p< 0.001), M2 oocytes (rho=0.624, p<0.001), grade A embryos (rho=0.419, p<0.001), and grade AB embryos (rho=0.446, p<0.001. In contrast, AMH levels had negative associations with the number and duration of cycles (p<0.05). AMH emerged as a statistically significant independent predictor of the number of M2 oocytes.

Serum AMH level could represent the quantity and quality of oocytes following IVF/ICSI treatments. Future studies should aim to delve deeper into the correlations between AMH levels and both the quality and quantity of embryos. Additionally, it would be beneficial to consider the influence of sperm factors, as well as assess pregnancy rates.

Pyogenic sterile arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome is a rare autosomal dominant autoinflammatory disorder caused by mutations in the PSTPIP1/CD2BP1 gene. We systematically reviewed 93 patients with PAPA and PAPA-like syndrome. Most patients were male (65.9%) mainly born to non-consanguineous parents. The median (IQR) age at the onset of symptoms and diagnosis was 6.0 (2.0-8.0) and 25.0 (7.0-32.0) years, respectively. 62.5% of patients were presented with arthropathies and septic arthritis was the most common (54.2%) initial diagnosis. Joint disorders were the most common findings (n=71, 78.9%) starting at the median (IQR) age of 4.0 (2.0-8.0) years, mainly in the knee (56.5%), ankle (36.9%), and elbow (47.8%).
Skin involvement (62 (66.7%)) initially presented at a median (IQR) age of 12.0 (20.-10.0) years and included pyoderma gangrenosum (n=41, 44.1%), acne (n=43, 46.2%), and nodulocystic acne (n=19, 20.4%).
There was a stronger association between skin manifestations and the development of the classic triad (P<0.001) compared to joint disorders (P=0.05) and patients with lower age of onset were more prone to the progression of the complete triad (P=0.18). Corticosteroids (n=45, 50.0%) with or without anakinra (33.3%) were the treatments applied in the majority of patients.
PAPA/PAPA-like syndromes involve mainly non-axial joints in early childhood and later skin in the second decade of life. Only 26.4% of the patients manifested the classical triad of PAPA syndrome. There is no clear genotype-phenotype association in these disorders. More studies are required to investigate the therapeutic options in PAPA/PAPA-like syndromes.

Lipopolysaccharide-responsive beige-like anchor (LRBA) deficiency is an inborn error of immunity characterized by a heterogeneous spectrum of manifestations, including enteropathy, immune dysregulation, and autoimmune disorder. Joint involvement has been less frequently reported, and limited data regarding its clinical presentation in LRBA deficiency has been published.

We reported an Iranian girl who was initially presented with recurrent respiratory tract infections and otitis media, later complicated by arthritis, growth failure, and organomegaly. The diagnosis of LRBA deficiency was confirmed by the identification of a novel homozygous missense variant in the LRBA gene (c.7742T>A, p.M2581K). Along with this report, a literature review focused on joint involvement, on 26 patients with LRBA deficiency was performed.

Non-infectious manifestations such as joint involvement have a broad spectrum in LRBA deficiency. For the timely diagnosis and appropriate clinical management, LRBA deficiency should always be kept in mind as a differential diagnosis in patients with joint involvement and clinically typical immune dysregulation.

Coronavirus disease 2019 (COVID-19) is an emerging worldwide issue, that has affected a large number of people around the world. So far, many studies have aimed to develop a therapeutic approach against COVID-19. Montelukast (MK) is a safe asthma controller drug, which is considered as a potential antiviral drug for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This review has a systematic approach to investigate the reports on the use of MK as a part of treatment or a prophylactic agent in COVID-19. The search was conducted in PubMed, Web of Science, and Scopus databases and yielded 35 studies containing the influence of MK on SARS-CoV-2. Ultimately, MK appears to be worth being used as an adjuvant therapeutic and prophylactic drug against SARS-CoV-2. Nevertheless, more clinical trials are required to accurately investigate its effectiveness.
