The management of immune thrombocytopenic purpura (ITP) involves several lines of therapy such as corticosteroids and intravenous immunoglobulin. With the emergence of novel therapies such as thrombopoietin receptor agonists (TPO-RAs), there has been a shift in treatment modalities. Eltrombopag and romiplostim have proven to be effective in the management of ITP through clinical studies, but their safety in pregnancy remains uncertain. The purpose of the study is to review the literature to evaluate the safety of TPO-RAs in pregnant women. Ten case reports and a cohort study pertaining to the use of TPO-RAs in pregnancy were obtained. According to the reported cases and prospective study, the use of eltrombopag and romiplostim appears to be relatively safe in the first, second, and third trimesters, as there were no reported congenital malformations. Low fetal birth weight has been observed following the administration of eltrombopag during the second trimester, whereas preterm birth has occurred following the administration of eltrombopag in the third trimester. Eltrombopag and romiplostim seem relatively safe. Further studies are necessary to clarify their safety during pregnancy.

Background: Small cell lung cancer (SCLC) accounts for approximately 13% of all lung cancer diagnoses each year. SCLC is characterized by a rapid doubling time, early metastatic spread, and an unfavorable prognosis overall. Areas of Uncertainty: Most patients with SCLC will respond to initial treatment; however, the majority will experience a disease recurrence and response to second-line therapies is poor. Immune checkpoint inhibitors may be an option given the success in other diseases. Data Sources: A literature search was conducted using Medline (1946–July week 1, 2017) and Embase (1996–2017 week 28) with the search terms small cell lung cancer combined with nivolumab or ipilimumab or pembrolizumab or atezolizumab or tremelimumab or durvalumab. Five clinical trials, including extended follow-up for 2, that evaluated immune checkpoint inhibitors in limited stage or extensive stage SCLC were included. Results: In 2 phase 2 trials, ipilimumab was added to upfront chemotherapy. In both trials, an improvement in progression-free survival was seen. Toxicity, when combined with a platinum and etoposide, was significant. In a confirmatory phase 3 trial, ipilimumab did not prolong overall survival when added to first-line chemotherapy. Overall, response rates were similar between the placebo and ipilimumab groups. A phase 1/2 trial evaluated nivolumab alone or in combination with ipilimumab in recurrent SCLC. Results revealed that nivolumab monotherapy and the combination of nivolumab and ipilimumab were relatively safe and had antitumor activity. Pembrolizumab has been evaluated in a multicohort, phase 1b trial. Preliminary data showed a durable response in the second-line setting. Conclusion: Given the lack of overall survival data and significant toxicity associated with the combination of ipilimumab with first-line chemotherapy, this treatment is not a reasonable option at this time. Nivolumab alone or in combination with ipilimumab is a valid option for recurrent SCLC.

Parenteral nutrition (PN) is essential for patients who are unable to tolerate oral or enteral feeding, providing them with necessary nutrients intravenously, including dextrose, amino acids, electrolytes, vitamins, trace elements, and lipid emulsions. Clinical pharmacists (CPs) play a critical role in PN management by ensuring proper formulation, monitoring therapy, preventing complications, and optimizing patient outcomes. In Saudi Arabia, limited literature exists on CPs’ involvement in total parenteral nutrition (TPN) administration, health information management (HIM) systems, and pharmacist staffing ratios. This paper examines the evolving role of CPs in PN management, addressing key challenges such as the optimal patient-to-CP ratio, the impact of HIM systems on PN prescribing, and the advantages and limitations of centralized versus decentralized PN prescription models. It highlights the need for standardized staffing levels, structured pharmacist training, and improved HIM integration to enhance workflow efficiency and prescribing accuracy. Additionally, the study examines how the adoption of advanced HIM systems can streamline documentation, reduce prescribing errors, and enhance interdisciplinary collaboration. This paper provides a framework for optimizing PN delivery, enhancing healthcare quality, and strengthening CPs’ contributions to nutrition support by addressing these factors. Implementing these recommendations will improve patient outcomes and establish a more efficient PN management system in Saudi Arabia, reinforcing the vital role of CPs in multidisciplinary care.

Background: The management of Acute Myeloid Leukemia (AML) during pregnancy remains challenging as both the maternal and fetal outcomes should be considered. Several reports suggested that chemotherapy can be administered safely during the second and third trimester of pregnancy. However, the use of 5-azacytidine presents limitation due to lack of data.Case presentation: A 28-years-old woman in the 26th week of gestation diagnosed with FLT3/ITD-mutated AML, complete remission was induced by Daunorubicin and Cytarabine, and subsequently with 5-azacytidine (75 mg/m2 daily for 7 days) with no fetal hematological or toxicity issues. Fetal ultrasound showed no aberrant morphology. Fetal size below the 5th percentile with normal umbilical artery dopplers, normal middle cerebral artery dopplers and ductus venosus doppler.Three weeks post 5-azacytidine, the team determined the most appropriate time for delivery after balancing the risks of prematurity and prevention of disease relapse since patient in hematological remission. The patient underwent elective lower segment caesarian section and had a baby girl delivered at 35 weeks of gestation weighing 1670 g without apparent anomalies.Conclusion: Treatment using 5-azacytadine during last trimester of pregnancy resulted in no major fetal and maternal complications. These findings concluded that 5-azacytadine during the third trimester of pregnancy seems to be safe however, potential risks of this agent should be considered.

Background: Cancer care is posing immense challenges to healthcare systems globally. Advances in screening, monitoring, and treating cancer improved patient outcomes and survival rates yet amplified the disease burden. Multiple barriers might impede early access to innovative therapies. We thoroughly examined the current challenges in oncology medication access in Saudi Arabia and provided consensus recommendations to revitalize the process. Methods: A focus group discussion was conducted. Expert healthcare providers (pharmacists and physicians) were invited to participate based on prespecified criteria. The research team conducted a qualitative analysis of the discussion to identify themes and formulate recommendations. Results: Fourteen experts were equally distributed into two groups, limiting the number in each group to 7. Pharmacists were 12 (∼86%), and physicians were 2 (∼14%). Ten were practicing in governmental hospitals, four representing different sectors; regulatory bodies, including Ministry of Health, National Unified Procurement Company, and Saudi Food and Drug Authority. Five themes were identified: national cancer burden, local data availability, pharmacoeconomic evaluation, patients reported outcomes, administration, and procurement. Consensus recommendations were formulated to optimize the formulary management process, enabling informed decision-making and facilitating early medication access for cancer patients. Conclusions: The formulary management process can be enhanced by addressing the national cancer burden, promoting local data availability, conducting pharmacoeconomic evaluations, focusing on patient outcomes, and improving administration and procurement procedures. Implementing these recommendations can improve access to oncology medications and improve patient care outcomes in Saudi Arabia.
