Background: Immune thrombocytopenia (ITP) is an autoimmune condition characterized by low platelet count and increased risk of bleeding. Several pathophysiological processes contribute to the disease, including complement activation by autoantibodies bound to platelet surfaces. This study aimed to assess complement levels in ITP patients and determine their correlation with clinical presentation and disease severity.Patients and methods This case–control study enrolled 40 patients (both sexes, aged 18–40 years) with primary ITP and 40 healthy controls. All participants underwent a comprehensive health assessment, thorough physical examination, laboratory investigations, and abdominal ultrasound. These included a complete blood count (CBC) with blood film, renal and hepatic function tests, hepatitis B surface antigen (HBsAg), hepatitis C virus antibodies (HCV-Abs), human immunodeficiency virus (HIV) antibodies, hepatitis B core antibody (HBcAb), C-reactive protein (CRP), antinuclear antibody (ANA), thyroid-stimulating hormone (TSH), erythrocyte sedimentation rate (ESR), serum complement levels (C3 and C4), and Helicobacter pylori antigen in stool. Results: Mean C3 and C4 levels were significantly lower in patients with ITP than in healthy controls. A statistical significant negative correlation was found between CRP and C4 levels in ITP patients. However, no statistically significant relationship was observed between C3 and C4 levels and platelet count in ITP patients, regardless of the presence of bleeding complications. Conclusion Complement levels were significantly lower in patients with ITP than in healthy controls. Complement levels were also significantly lower in treatment-naïve patients than in patients who received treatment. Therefore, complement levels could serve as a valuable laboratory test for disease activity.

Objective: Hepatitis C virus (HCV) infection is known to influence the seminal and hormonal parameters of infected men. This study was performed to assess the effects of HCV clearance using direct-acting antiviral (DAA) agents on semen and hormonal parameters. Methods: A total of 50 patients with chronic HCV were enrolled, and conventional semen analysis was performed according to World Health Organization guidelines. Basal levels of total testosterone, free testosterone (FT), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), prolactin, and sex hormone-binding globulin (SHBG) were assessed before and 3 months after treatment with DAAs. Results: Following DAA treatment, statistically significant increases were observed in sperm motility and the proportion of grade A sperm. Additionally, the percentage of abnormal forms was significantly decreased after treatment (p=0.000). However, no significant differences were observed in semen volume, concentration, or total sperm count. Sex hormone analysis of patients after DAA treatment revealed significant increases in FT, LH, and FSH levels, along with significant decreases in SHBG, prolactin, and E2 levels. Conclusion Following HCV clearance, we noted an improvement in sperm motility and an increase in the percentage of sperm with normal morphology. Treatment with DAAs was also associated with increased levels of FT and LH, along with decreased levels of SHBG, prolactin, and E2.

Purpose: Allgrove syndrome, also known as “triple A” syndrome, is characterized by adrenal insufficiency, achalasia, and alacrimia. When neurological signs are also present, the condition is referred to as “4 A” syndrome. Methods: We conducted a retrospective analysis of three patients with 4 A syndrome confirmed genetically. A complete neurological exam was carried out by an experimented neurologist. Results: Herein, we describe the neurological characteristics often associated with this condition, through the clinical and electrophysiological analysis of three patients. All patients exhibited a mutation in AAAS, the gene coding for ALADIN. While these individuals presented with the classic features of triple-A syndrome, neurological symptoms were not prominent. Conclusion The neurological manifestations of Allgrove syndrome have historically been overlooked and inadequately explored. Due to the condition’s rarity and substantial phenotypic heterogeneity, only recently have a variety of symptoms been recognized and described.

Objective: This study was conducted to investigate the impact of previous delivery mode on pregnancy outcomes in patients with secondary infertility after frozen-thawed embryo transfer. Methods: This prospective observational study included 140 patients experiencing secondary infertility. Of these, 70 patients had a previous cesarean delivery (CD), while the remaining 70 patients had a previous normal vaginal delivery (NVD). The primary outcome was the implantation rate. The secondary outcomes included rates of clinical pregnancy, chemical pregnancy, miscarriage, and ectopic pregnancy. Results: The comparison of all fertility outcomes between the two groups revealed no statistically significant differences. The implantation rate was 40.4% in the CD group and 41.7% in the NVD group (p=0.842). The clinical pregnancy rate was 50% in the CD group and 49.3% in the NVD group (p=0.932), while the chemical pregnancy rate was 14.6% in the CD group and 19% in the NVD group (p=0.591). The miscarriage rates in the CD and NVD groups were 20% and 17.6%, respectively (p=0.803). One case of tubal ectopic pregnancy occurred in the NVD group (1.4%). Conclusion The mode of prior delivery did not significantly impact pregnancy outcomes following frozen-thawed embryo transfer.

Background: The clinical use of sildenafil citrate (Viagra), a drug used to treat erectile dysfunction, is limited because of its many side effects on tissues. In this context, we aimed to investigate the protective effects of hesperidin, a citrus flavonoid, on hepatic and testicular damage induced by a high dose of sildenafil citrate in male rats. Rats were randomly divided into four groups. The first group was used as the control group. The second group was orally administered sildenafil citrate at a high dose of 75 mg/kg thrice a week. In the third group, hesperidin was administered orally at a dose of 50 mg/kg/day. The fourth group was administered 75 mg/kg sildenafil citrate three times a week with 50 mg/kg hesperidin daily. The experiment lasted for 28 days. Results: In the sildenafil-treated groups, blood indices were altered, liver function tests were deranged, and serum testosterone levels were reduced. In the liver and testicular tissue, sildenafil citrate treatment resulted in significant reductions in catalase and total antioxidant capacity; as well as increased malondialdehyde, reactive oxygen species, and nitrous oxide levels. In addition, sildenafil citrate treatment caused abnormal histopathological patterns in both the liver and the testes. Liver vascular endothelial growth factor and testicular steroidogenic acute regulatory protein gene expression were upregulated. Conclusions Hesperidin attenuated the harmful effects of intensive sildenafil citrate treatment on liver and testicular functions, alleviated oxidative stress and normalized blood indices. Therefore, hesperidin could be protective against sildenafil citrate-induced oxidative damage that may develop over the long term.

Objectives: To assess the predictive value of the initial uterine artery Doppler indices, the pulsatility index (PI), and resistance index (RI) in the prediction of heavy menstrual bleeding before and after copper intrauterine contraceptive device (IUCD) insertion. Methods: The current prospective clinical study included 100 women who intended to use a copper IUCD (Cu T-380A) and met the inclusion criteria. Uterine artery Doppler PI and RI indices were calculated before IUCD insertion and at three and six months after insertion. Based on the presence or absence of menorrhagia, all women were classified into two groups: non-bleeding (n=52) and extreme menstrual bleeding (n=48). Receiver operating curve analysis was used to determine the predictive value of uterine artery PI and RI in patients with menorrhagia relevant to IUCD. Results: The PI and RI indices displayed a highly significant difference between the IUCD groups at three and six months after insertion (P<0.001). Uterine artery PI ≤2.02 (sensitivity of 95.8%, specificity of 100%, and area below the curve [AUC] of 0.97 at P-value<0.001) and RI ≤0.83 (sensitivity of 93.8%, specificity of 100%, and AUC of 0.949 at P-value<0.001) were correlated with significant menstrual bleeding following insertion of IUCD. Conclusion The presented results confirmed our assumption that the initial studies of uterine artery Doppler can predict heavy-menstrual bleeding associated with IUCD and therefore, should be conducted in women pursuing reversible longacting contraception.
