Abstract
Cyclophosphamide (CP) is a popular cancer treatment; however, despite its efficacy, it is known to cause harm to the testicles. To mitigate the reproductive damage caused by CP in male rats, we examined the protective effect of azilsartan (AZ) on CP-induced testicular damage. Thirty Sprague-Dawley male rats were equally divided into three groups: normal control group: received 0.5% CMC suspension for 13 days; induction group: received a single dose of 200 mg/kg of CP on day 6 by intraperitoneal (IP) injection, azilsartan group: received azilsartan (4 mg/kg) orally for 5 days followed by a single dose of 200 mg/kg of (CP) on day 6 by IP injection, then azilsartan administered again for 7 days. Animals were sacrificed on day 14, and sperm characteristics, testosterone levels, and testicular histopathology were evaluated. Induction with CP caused a significant reduction in median value compared to normal control in sperm count (12.0 vs. 22.0 × 106/mm3), sperm motility (30 vs. 90%), abnormal sperm (30.32 vs. 14.43%), dead sperm count (32.43 vs. 10.49 × 106/mm3), DNA fragmentation (21.57 vs. 5.49%); meanwhile, azilsartan prevent these effects on median sperm count (17.0 × 106/mm3), sperm motility (70.0%), abnormal sperm (23.19%), dead sperm count (26.17 × 106/mm3), DNA fragmentation (13.81%), and improved plasmatic testosterone levels compared to the CP group and prevented histopathological alterations of the testes. Azilsartan's mitigation of CP's effects suggests it can prevent male rats' reproductive damage caused by CP. One possible explanation for AZ's protective effects is that it inhibits lipid peroxidation and has antioxidant properties.

Abstract
Autoimmune encephalitis is increasingly recognized as a neurologic cause of acute mental status changes with similar prevalence to infectious encephalitis. Despite rising awareness, approaches to diagnosis remain inconsistent and evidence for optimal treatment is limited. The following Canadian guidelines represent a consensus and evidence (where available) based approach to both the diagnosis and treatment of adult patients with autoimmune encephalitis. The guidelines were developed using a modified RAND process and included input from specialists in autoimmune neurology, neuropsychiatry and infectious diseases. These guidelines are targeted at front line clinicians and were created to provide a pragmatic and practical approach to managing such patients in the acute setting.

Front Pharmacol 2023; 14:1324339. [PMID: 38143498 PMCID: PMC10746162 DOI: 10.3389/fphar.2023.1324339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Accepted: 11/24/2023] [Indexed: 12/26/2023] Open
Abstract
Introduction: Malignant bone and soft tissue tumors, commonly called sarcomas, predominantly originate in bone and soft tissues and typically affect individuals at a younger age. Following the resection of the primary tumor, treatment often necessitates radiation therapy and gonadotoxic chemotherapy, the specifics of which depend on the disease's stage Conversely, there is a notable concern regarding the potential loss of fertility due to these treatments. Consequently, it is recommended that men consider sperm cryopreservation before initiating treatment. This study aims to assess spermatogenesis in male patients diagnosed with malignant bone and soft tissue tumors before and after chemotherapy. Methods: This study involved 34 male patients diagnosed with malignant bone and soft tissue tumors and subsequently underwent sperm cryopreservation before initiating treatment. Medical records included details about the primary disease, age, marital status at presentation, semen analysis results, treatment regimen and number of courses, post-treatment semen analysis, renewal status and outcomes. Results: The mean age at the time of sperm cryopreservation was 22.8 years. The median semen volume was 2.5 mL, sperm concentration was 32.6 million/ml, and sperm motility was 38.5%. Following chemotherapy, semen analysis was conducted on 12 patients, with ifosfamide being the predominant drug used in all cases. Among these 12 patients, eight retained viable spermatozoa, and two successfully achieved spontaneous pregnancies resulting in live births. In one of the remaining four cases where no sperm were detected in ejaculate, a live birth was achieved through intracytoplasmic sperm injection using cryopreserved sperm. Discussion: While ifosfamide, the primary chemotherapy drug for patients with malignant bone and soft tissue tumors, was associated with severe impairments in spermatogenesis, recovery of spermatogenesis was observed in many cases. However, there were instances of prolonged azoospermia. Even in such cases, assisted reproduction using cryopreserved sperm remained viable for achieving parenthood. In light of these findings, offering patients the opportunity for fertility preservation is advisable.

Chronic kidney disease, female infertility, and medically assisted reproduction: a best practice position statement by the Kidney and Pregnancy Group of the Italian Society of Nephrology. J Nephrol 2023; 36:1239-1255. [PMID: 37354277 PMCID: PMC11081994 DOI: 10.1007/s40620-023-01670-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/01/2023] [Indexed: 06/26/2023]
Abstract
Fertility is known to be impaired more frequently in patients with chronic kidney disease than in the general population. A significant proportion of chronic kidney disease patients may therefore need Medically Assisted Reproduction. The paucity of information about medically assisted reproduction for chronic kidney disease patients complicates counselling for both nephrologists and gynaecologists, specifically for patients with advanced chronic kidney disease and those on dialysis or with a transplanted kidney. It is in this context that the Project Group on Kidney and Pregnancy of the Italian Society of Nephrology has drawn up these best practice guidelines, merging a literature review, nephrology expertise and the experience of obstetricians and gynaecologists involved in medically assisted reproduction. Although all medically assisted reproduction techniques can be used for chronic kidney disease patients, caution is warranted. Inducing a twin pregnancy should be avoided; the risk of bleeding, thrombosis and infection should be considered, especially in some categories of patients. In most cases, controlled ovarian stimulation is needed to obtain an adequate number of oocytes for medically assisted reproduction. Women with chronic kidney disease are at high risk of kidney damage in case of severe ovarian hyperstimulation syndrome, and great caution should be exercised so that it is avoided. The higher risks associated with the hypertensive disorders of pregnancy, and the consequent risk of chronic kidney disease progression, should likewise be considered if egg donation is chosen. Oocyte cryopreservation should be considered for patients with autoimmune diseases who need cytotoxic treatment. In summary, medically assisted reproduction is an option for chronic kidney disease patients, but the study group strongly advises extensive personalised counselling with a multidisciplinary healthcare team and close monitoring during the chosen medically assisted reproduction procedure and throughout the subsequent pregnancy.
