The modulating effects of astaxanthin on apoptosis in women with polycystic ovarian syndrome: A randomized clinical trial.

Objective: Astaxanthin (ASX) is a lipid-soluble keto-carotenoid with several biological effects. These effects may benefit polycystic ovarian syndrome (PCOS) patients. Imbalanced apoptosis/anti-apoptosis signaling has been considered the major pathogenesis of PCOS. In a randomized clinical trial, we tested the impact of ASX on the apoptotic pathway in PCOS granulosa cells (GCs). The present study hypothesizes that ASX may improve apoptosis in PCOS patients. Materials and Methods: This trial recruited patients with confirmed PCOS. A total of 58 patients were randomly assigned to take ASX (12 mg) or placebo for 8 weeks. Aspirated follicular fluid (FF) and blood samples were taken from both groups to measure BAX and BCL2 protein expression. Following FF aspiration, GCs from both groups were obtained; Real-Time PCR and Western blotting were used to evaluate the apoptotic pathway's gene and protein expression levels in GCs.BAXBCL2. Results: In GCs analysis, ASX reduced DR5 gene and protein expression after 8 weeks compared to placebo(p<0.05). Also, Caspase8 (p>0.05) and BAX (p<0.05) gene expression declined, although the difference was not statistically significant for Caspase8. Besides,ASX treatment contributed to an elevated BCL2 gene expression in GCs(p<0.05). In FF and serum analysis, a statistically significant increase was found in BCL2 concentration in the ASX group (p<0.05). Moreover, a reduction in BAX level was confirmed in both FF and serum of the ASX group; however, this change was not significant in the serum (p>0.05). Conclusion: It seems that ASX consumption among women with PCOS improved serum and FF levels of apoptotic factors and modulated genes and protein expression of the apoptosis pathway in GCs. Nevertheless, further investigations are needed to reveal the potential role of this compound in PCOS treatment.

Astaxanthin treatment ameliorates ER stress in polycystic ovary syndrome patients: a randomized clinical trial.

Astaxanthin (ASX), as a natural carotenoid compound, exists in various types of seafood and microorganisms. It has several possible beneficial therapeutic effects for patients with polycystic ovary syndrome (PCOS). Patients with PCOS also suffer from endoplasmic reticulum (ER) stress. In the present work, it was hypothesized that ER stress could be improved by ASX in PCOS patients. Granulosa cells (GCs) were obtained from 58 PCOS patients. The patients were classified into ASX treatment (receiving 12 mg/day for 60 days) and placebo groups. The expression levels of ER stress pathway genes and proteins were explored using Western blotting and quantitative polymerase chain reaction. To assess oxidative stress markers, follicular fluid (FF) was gained from all patients. The Student's t test was used to perform statistical analysis. After the intervention, ASX led to a considerable reduction in the expression levels of 78-kDa glucose-regulated protein (GRP78), CCAAT/enhancer-binding protein homologous protein (CHOP), and X-box-binding protein 1 compared to the placebo group, though the reduction in the messenger RNA (mRNA) expression level of activating transcription factor 6 was not statistically significant. However, ASX significantly increased the ATF4 expression level. GRP78 and CHOP protein levels represented a considerable decrease in the treatment group after the intervention. In addition, a statistically significant increase was found in the FF level of total antioxidant capacity in the treatment group. Based on clinical outcomes, no significant differences were found between the groups in terms of the oocyte number, fertilization rate, and fertility rate, but the ASX group had higher rates of high-quality oocytes, high-quality embryo, and oocyte maturity compared to the placebo group. Our findings demonstrated that ER stress in the GCs of PCOS patients could be modulated by ASX by changing the expression of genes and proteins included in the unfolding protein response.Trial registration This study was retrospectively registered on the Iranian Registry of Clinical Trials website ( www.irct.ir ; IRCT-ID: IRCT20201029049183N, 2020-11-27).

Postpartum Multiple Colon Perforation after Cesarean Section in COVID-19 Patients: A Case Series.

Introduction: Gastrointestinal symptoms are present in 50% of polymerase chain reaction (PCR)-positive COVID-19 patients. In addition, bowel abnormalities are a common finding of COVID-19, and bowel-wall disorder is reported in 31% of computed tomography images of COVID-19 patients. Case History: We report three postpartum cases with colon perforation after Cesarean section and positive PCR for SARS-CoV-2-RNA and during the main peak of COVID-19 pandemic, who were managed by early detection, laparotomy, and effective treatment and were discharged and followed up. Conclusion: A colonic perforation could be considered as one of the causes of abdominal pain especially in women with a past surgical history as well as patients with infectious diseases such as COVID-19. Therefore, abdominal and pelvic ultrasound or x-ray was strongly recommended for postpartum women with abnormal abdominal distension, gastrointestinal symptoms, and pain to prevent possible fetal complications.

Basal serum cortisol and adrenocorticotropic hormone levels in patients with atopic dermatitis.

BACKGROUND: Certain studies suggest that percutaneous absorption of topical steroids may cause suppression of hypothalamic-pituitary-adrenal axis (HPAA) in atopic dermatitis (AD) patients. This study aimed to investigate the basal serum cortisol, adrenocorticotropic hormone (ACTH), and IgE levels in patients with AD and their correlation with the disease severity. METHODS: Levels of basal serum cortisol, ACTH, and IgE were assessed by ELISA in 31 patients with AD and 31 controls. Clinical severity of AD was evaluated by the scoring of atopic dermatitis (SCORAD) index. RESULTS: No statistical difference was observed between the two groups for basal serum cortisol and ACTH levels. The serum IgE level was significantly higher in the AD group. The SCORAD index was correlated with serum IgE level. CONCLUSIONS: Basal serum cortisol and ACTH levels are normal in AD patients. Serum IgE level is significantly higher in AD patients and is correlated with the disease severity.

Uric Acid: a new antioxidant in patients with pemphigus vulgaris.

BACKGROUND: Increased reactive oxygen species (ROS) and lipid peroxidation are seen in many dermatologic disorders, for example, atopic dermatitis, psoriasis, vitiligo, acne vulgaris, pemphigus vulgaris (PV), lichen planus, and alopecia areata. ROS has an important role in the inflammation process. In PV, increased production of ROS leads to decline of antioxidants in plasma and red blood cells which results in oxidative stress. We aimed to evaluate the level of these antioxidants in PV patients and compare it to the controls. MATERIALS AND METHODS: Among patients attending the dermatology clinics, 30 patients with PV, who had never been on treatment, were enrolled to the study. The control group consisted of 30 age- and sex-matched healthy non-smoker individuals. Venous blood was collected from the subjects for the evaluation of plasma levels of glutathione peroxidase, vitamin C, selenium, bilirubin, and uric acid. RESULTS: Age mean and standard deviation of the patients (40.83, 12.74) was comparable to the controls (41.96, 13.08). Mean level of uric acid was significantly lower in PV patients compared to the controls (P = 0.006). Other antioxidants were not different between the two groups. Uric acid of the patients with mucosal involvement was significantly lower than patients with mucocutaneous involvement (P = 0.049). LIMITATIONS: The blood level of other antioxidants (e.g. malondialdehyde) was not evaluated. CONCLUSIONS: Uric acid as an antioxidant in our study had similar changes to previous studies in the field of other diseases but selenium, bilirubin, and glutathione peroxidase did not differ between patients and controls.

An ulcerated tumor in an infant.

Cutaneous leiomyoma is a benign dermal tumor of smooth muscle. Leiomyoma can occur at any age but typically develops during adolescence or early adult life. Congenital leiomyoma is an extremely rare reported variant. A five-month-old boy presented to our clinic with a progressively enlarging mass on his occipital scalp. Microscopic examination of the solitary ulcerated nodule showed a non-encapsulated mass in the dermis composed of spindle-shaped cells. The diagnosis was confirmed by immunohistochemical studies, which were compatible with leiomyoma. Therefore, clinical suspicion of leiomyoma should be considered in the case of a solitary ulcerated nodule in an infant.
