Linear immunoglobulin A bullous dermatosis induced by atezolizumab.

Linear immunoglobulin A bullous dermatosis (LABD) is a rare immune-mediated vesiculobullous disease that is reported to be induced by infections or medications. Atezolizumab is a monoclonal antibody that targets programmed cell death ligand-1 and has been used to treat multiple cancers. Here, we report a case of drug induced LABD following the administration of Atezolizumab.

Assessing the Inhospital Complications in Patients Postrenal Transplantation, in a Tertiary Care Center, Riyadh, Saudi Arabia.

Complications of chronic kidney disease (CKD) can range from localized to systemic manifestations that can worsen patients' outcomes. CKD results in irreversible deterioration in renal function, which ultimately progresses to end-stage renal failure and necessitates the need for renal transplantation. Our study aimed to identify patients' complications postrenal transplant during hospitalization and assess the main factors affecting these patients' outcomes and survival rates. This study is a single-centered, retrospective cohort chart review conducted from January 2016 to March 2019. The collected data parameters included patients' characteristics (e.g., gender, age, body mass index), as well as surgical-related details and postoperative complications. Microsoft Excel and IBM SPSS Statistics version 22.0 were used for data entry and analysis. The descriptive statistics were presented as frequency and percentage for the categorical variables (e.g., gender and smoking status), while the mean ± standard deviation was used for numerical variables. A total of 80 posttransplant patients who fulfilled the inclusion criteria were recruited. Urogenital complications were the most commonly seen during the postoperative period, especially developing urinary tract infections by 16%. During our study, the rate of complications was considered minimal and not significant in assessing posttransplant patients.

Genetic Profile of Epidermolysis Bullosa Cases in King Abdulaziz Medical City, Riyadh, Saudi Arabia.

Epidermolysis bullosa (EB) is a rare heterogeneous genetic mechanobullous skin disorder that is characterized by increased skin fragility leading to blistering following minor trauma. EB may be inherited as an autosomal dominant or an autosomal recessive disorder and can be classified into dystrophic EB (DEB), junctional EB (JEB), and EB simplex (EBS). A total of 28 Saudi patients with EB were included in this observational, retrospective chart-review study. A consecutive non-probability sampling technique was used to approach all affected patients. Molecular analysis was done to test the patients' genomic DNA using a custom-designed AmpliSeq panel of suspected genes. All disease-causing variants were checked against available public databases. Twelve patients (42.9%) were found to have DEB, 6 patients (21.4%) with JEB, and 10 patients (35.7%) with EBS. The molecular genetic results revealed detections of 24 various homozygous genetic variations in the genes associated with EB, of which 14 were novel mutations. The most frequent variations were detected in COL7A1 in 12 cases (42.9%), followed by LAMB3 in 5 cases (17.9%), TGM5 in 4 cases (14.3%), and other genes. Furthermore, the majority (87.5%) of EB cases were confirmed to have homozygous mutations, and few were documented with positive consanguinity history. Only 3 cases (12.5%) were found to be autosomal dominant displaying heterozygous mutations. This is the first study to establish the EB genetic profile in Saudi Arabia where DEB is the most frequent type. A total of 14 novel mutations were identified that had not been previously reported. Consanguineous marriage is clearly recognized in the Saudi population; therefore, we propose a nationwide EB program that would help extend the spectrum of the genetic profile and help in the diagnosis and better understanding of this disease.
