Introduction: Immune checkpoint inhibitors (ICIs) are recommended for various types of cancer. On the other hand, these ICIs may cause immune-related adverse events (irAEs). Lichen sclerosus (LS) and lichen planus (LP) are two distinct phenotypes of irAEs that occur in a subset of patients treated with ICIs. These adverse effects have a detrimental effect on the patient’s quality of life and treatment phases; however, the clinical evaluation and assessment of LS and LP remain uncertain. This study aims to assess and evaluate the risk of LS and LP associated with the use of ICIs via a systematic review of the literature and the USA FDA Adverse Events FAERS database. Method: The study searched electronic databases such as PubMed, Medline, Cochrane, and Google Scholar for case reports on immune-checkpoint-inhibitor-associated lichen sclerosus and lichen planus published in English between inception and 31 December 2021. The FDA’s adverse event reporting system (FAERS) database was also analyzed. Results: Thirty-eight case reports and two retrospective studies with a total of 101 patients, in addition to the FAERS data, were evaluated. More cases involved lichen planus (78.9%) than lichen sclerosis (21%). Nivolumab and pembrolizumab were most frequently reported with LS and LP, among other ICIs. Thirty-six out of thirty-eight patients with LS or LP experienced complete remission, while two patients experienced partial remission. Most of the cases had an excellent response to corticosteroids (92.1%), while the remainder had moderate (5.2%) and poor (2.6%) responses. Additionally, the reporting odds ratio (ROR) of the FAERS database indicated a favorable association for ICIs, the risk of LP, and LS. A stronger association was uniquely found between nivolumab and pembrolizumab. Conclusion: There have been published case reports for these adverse events. Healthcare providers should be aware of the possibility of lichen sclerosis and lichen planus developing in patients receiving ICIs which could necessitate hospitalization or discontinuation. Regulatory agencies are advised to monitor the risks as a potential safety signal.

Solid organ transplant (SOT) recipients are at increased risk of COVID-19 infection because of their suppressed immunity. The available data show that COVID-19 vaccines are less effective in SOT recipients. We aimed to assess the cellular and humoral immunogenicity with an increasing the number of doses of COVID-19 vaccines in SOT recipients and to identify factors affecting vaccine response in this population. A systematic review and meta-analysis were conducted to identify ongoing and completed studies of humoral and cellular immunity following COVID-19 vaccines in SOT recipients. The search retrieved 278 results with 45 duplicates, and 43 records did not match the inclusion criteria. After title and abstract screening, we retained 189 records, and 135 records were excluded. The reasons for exclusion involved studies with immunocompromised patients (non-transplant recipients), dialysis patients, and individuals who had already recovered from SARS-CoV-2 infection. After full-text reading, 55 observational studies and randomized clinical trials (RCTs) were included. The proportion of responders appeared higher after the third, fourth, and fifth doses. The risk factors for non-response included older age and the use of mycophenolate mofetil, corticosteroids, and other immunosuppressants. This systematic review and meta-analysis demonstrates the immunogenicity following different doses of COVID-19 vaccines among SOT patients. Due to the low immunogenicity of vaccines, additional strategies to improve vaccine response may be necessary.

Post-transplant anemia (PTA) is a common serious complication following kidney transplantation. It affects graft and patient survival. Anemia that presents within six months post-transplantation is defined as an early PTA. Late PTA is when anemia occurs more than six months following transplantation. Despite this, there are limited studies on the long-term impact of anemia on patient survival and graft function in kidney transplants. We conducted a retrospective study with long-term follow-up to investigate the effect of early and late PTA on patient and graft function within seven years and to estimate the prevalence of PTA at six months, two, four, and seven years postrenal transplantation along with the associated risk factors. A retrospective chart review of 145 adult patients who had kidney transplants from January 1 to December 31, 2015, and were followed up until December 31, 2022. Anemia was defined according to the World Health Organization (WHO) criteria of hemoglobin<12 gm/dl in females and<13 mg/dl in males. Pretransplant, six months, two, four, and seven years postrenal transplantation medications and laboratory data were obtained. Patients were excluded if they were pediatrics or had missing data. 180 patients were screened, and 145 patients met the inclusion criteria. The prevalence of early PTA was 8.3%. Trimethoprim-sulfamethoxazole was significantly associated with anemia within six months. The prevalence of anemia increased at two, four-, and seven-years post-transplant (24.8%, 24.8%, and 27.6%, respectively). Graft failure was significantly associated with late PTA at four and seven years (p-value < 0.001). P < 0.005, respectively). Death was reported for 3 patients, and it was significantly associated with late transplant anemia (p-value < 0.005), Cytomegalovirus was associated with anemia at 6 months and 2 years post-transplant and significantly associated with graft failure (p-value < 0.037). The results of this study indicate that post-transplant anemia is associated with graft failure and patient mortality. Therefore, managing anemia post-transplant should be addressed more carefully.

Diseases management has reached the highest level of complexity and cost in history, worldwide, and in Saudi Arabia in particular, which led to prolonged, unnecessary hospital stays. There have been many recent innovative measures to reduce these issues. One is to provide home infusion services. Hence, this narrative review emphasizes the expected benefits and challenges of such services and the applicability of their implementation in Saudi Arabia. A literature search was conducted via PubMed database, involving all published studies from inception until March 24th, 2023. Many studies showed positive impacts of home infusion on reducing the length of hospital stays, increasing cost-saving, and leading to high patient satisfaction.

Background: Pharmacovigilance (PV) is an essential part of the healthcare system’s framework. In Saudi Arabia, pharmacovigilance is still a relatively new concept though it is well established in many countries. Study Aim: In this study, we aim to evaluate knowledge, attitude, and practice regarding pharmacovigilance and barriers to reporting adverse drug reactions (ADRs) among the general public in Saudi Arabia. Methods: This is a cross-sectional study that used a self-administered online questionnaire to assess knowledge, attitude, and practice of PV and ADRs. The study included only the adult population in Saudi Arabia. A scoring system was generated with a scale from 0 to 100, where 80% was set as a cut-off point, as any higher score resembled adequate knowledge, a positive attitude, and good practice. We used the Statistical Package for Social Sciences (SPSS) version 26 for performing the statistical analysis, where para-normal tests were used to associate scores with the socio-demographic characteristics of participants. Results: The study collected 1098 complete responses. The mean age (±SD) of participants was 37.9± 11.2 years. Females comprised 68.9% of the participants. The average knowledge score among participants was 37.8± 18.5, where only 4.3% of respondents had adequate knowledge. The average attitude score was 90.1± 19.2, where 83.4% had a positive attitude. The average practice score was 70.4± 18, and 34.5% of participants had good practice. Conclusion: The study found that the majority of participants had inadequate knowledge, a positive attitude, and poor practice. Individuals holding a master’s degree or higher and those working in the healthcare sector had the highest knowledge scores, whereas the group aged 31 to 50 years old, participants from the Al Jawf region, participants who are married with children, holders of a master’s degree or higher, and healthcare workers had the best attitude scores. Higher practice scores were seen among married individuals with children and those who work in the healthcare sector.

Introduction: As the pharmaceutical advertising landscape evolves with digital advancements, this study examines public awareness and perceptions of medication advertisements in Saudi Arabia. It focuses on the effects of regulatory frameworks and evaluates how they influence public understanding and attitudes toward these advertisements. Method: A cross-sectional study was conducted using an electronic survey in Saudi Arabia in December 2023. The survey was distributed on social media platforms and reached a diverse sample of 440 participants. It covered public perception and attitudes toward drug advertisements, knowledge of regulatory laws, and preferences regarding advertising mediums. Results: Out of the 440 participants in the study, who were primarily employees with bachelor’s degrees, there was a clear awareness of drug advertisements. The average age of the group was 33 years, and a significant portion (71.1%) held a bachelor’s degree, with 51.1% being employed. The findings revealed that 25.5% of participants frequently noticed drug ads, while 22.7% saw them very often. Although many found the ads informative, there were significant concerns about unrealistic expectations and the risk of overmedication; 89.8% believed the ads set unrealistic expectations about the effectiveness of medications. Additionally, 60.7% thought that celebrity endorsements might mislead the audience, and 91.1% felt that ads should provide more detailed information about potential risks and side effects. Regarding preferred advertising platforms, mobile apps and websites were favored (47%), followed closely by social media (46.4%). A striking 93.2% of participants believed that drug ads on social media should be subject to stricter regulations, and 96.4% wanted more proactive monitoring of online advertising. Many also reported using other sources, such as medical review sites, to verify medication information. Conclusions: Pharmaceutical advertising in Saudi Arabia must balance ethical transparency with educational value. The influence of digital platforms underscores the necessity for stricter regulation and accurate information dissemination. A collaborative approach is essential to align advertising practices with public health interests and regulatory standards.
