Polypharmacy is a common problem among hemodialysis patients. It is associated with increased hospital admissions, morbidity, mortality, Medication-Related Problems (MRPs), and expenditures. There is a paucity of data on the prevalence of polypharmacy in our setting. This study aims to determine the prevalence of polypharmacy and MRPs and to assess its predictors. We conducted a cross-sectional study in the outpatient hemodialysis unit. A pharmacy resident assessed electronic prescribing records to identify MRPs and discussed therapeutic interventions to enhance effective therapeutic regimens over a three months period. Eighty-three patients were included. The median age was 63 (Interquartile range; IQR = 22), 50% were males, and the mean number of co-morbidities was 3.14 ± 1.64. The prevalence of polypharmacy was 97.6% with a 95% CI (91.6%–99.7%). Medication use without indication, was the highest identified MRPs at 36% (102/280), followed by subtherapeutic dosing at 23% (65/280), and overdosing at 15% (41/280). The number of comorbidities, the presence of ischemic heart disease, and respiratory diseases were the main predictors of the increased number of medications. Polypharmacy is highly prevalent among the Saudi hemodialysis population. A review of the medications prescribed by the pharmacist facilitated the identification of MRPs and provided opportunities for deprescribing to optimize medication use and to reduce polypharmacy in hemodialysis patients.

Chronic kidney disease (CKD) is a serious worldwide health problem with a rising incidence and prevalence. CKD can lead to end-stage renal failure that increases the risk of death and requires dialysis or kidney transplantation. Patients’ adherence, attitude, and knowledge are important to prevent and control CKD. The aim of this study was to investigate the awareness and knowledge about CKD and attitude toward kidney donation among the general population in Saudi Arabia. A cross-sectional study based on a questionnaire survey was conducted in Jeddah, Saudi Arabia. We surveyed the awareness about CKD among adult residents of Jeddah, Saudi Arabia. We used a self-administrated questionnaire that consisted of three sections; socio-demographic information, awareness about CKD, and attitude towards kidney donation. Simple descriptive statistics was employed using IBM SPSS Statistics version 24.0 software. The number of survey respondents was 268. More than half (53.7%) of the included participants knew that the use of non-steroidal anti-inflammatory drugs is a risk factor for CKD, whereas 54% thought that CKD could be diagnosed from a simple urine analysis, and 45% believed that lifestyle modifications can alter the course of the disease. Interestingly, most participants (57.4%) were ready to donate their kidney to a patient with end-stage renal disease, and 68.6% knew that patient can live with one kidney. The present study identifies a low rate of CKD awareness and calls for a need for awareness campaigns and other tools to strengthen knowledge dissemination. Improving public awareness about CKD needs to be addressed to help facilitate disease identification and prevention.

Background: Nonadherence to medications by patients requiring hemodialysis (HD) leads to unfavorable clinical outcomes. Limited data exist to demonstrate the effect of incorporating patient-centered interventions using concepts of medication therapy management and motivational interview by pharmacists on pharmacoadherence in patients requiring HD. Therefore, we assessed the impact of patient-centered pharmacist care on pharmacoadherence and its outcomes in patients requiring HD. Methods: Adult patients who had received outpatient HD for at least 3 months were enrolled. The study was conducted from October 2016 to April 2017. Pharmacists interviewed the patients at month 1, 2, 4 and 6, and the intervention (comprehensive review) occurred at months 3 and 5. The primary outcome was the change in pharmacoadherence as assessed by pre-HD serum phosphate levels and the differences in the number of medications between patient’ self-report and medications records at the electronic healthcare records (EHRs). The secondary outcomes included changes in systolic blood pressure (SBP), glycosylated hemoglobin levels, serum low-density lipoprotein (LDL) levels, and the prevalence and types of medication-related problems (MRPs). Results: Seventy-two patients were enrolled. Their median age was 59 (interquartile range: 47–67.5) years, and 53% were men. Pre- and post-intervention pharmacoadherence, as indicated by serum phosphate levels and the differences in the number of medications between patient’ self-report and the medication records at the EHRs, did not significantly differ (p = 0.682 and 0.348, respectively). Mean SBP and mean LDL did not significantly change post-intervention. The median number of MRPs declined between Months 3 and 5 (p = 0.002): the prevalence of MRPs at Month 3 was 44.9% (95 confidence interval [CI]: 40.4–49.3) and decreased to 29.8% (95 CI: 25.6–34.3) at Month 5. Drug use without indication was the most frequent MRP (23.9%). Conclusions: Patient-centered pharmacist care did not result in significant changes in pharmacoadherence. However, its clinical utility as a tool to identify and mitigate MRPs in patients requiring HD is indisputable. Trial Registration: ClinicalTrials.gov identifier: NCT03576404 (retrospectively registered on July 3rd, 2018).

Few data are available about the rate of short-term remission and its impact on the long-term outcomes of proliferative lupus nephritis in the Middle East. An observational study was carried out involving 96 adult patients with biopsy-proven focal or diffuse proliferative lupus nephritis (PLN) from four different hospitals. Data on induction, remission and long-term outcomes were collected and analyzed. Among the 96 patients with biopsy-proven PLN (median age 27 (IQR: 21,34) years, 85% women and median duration of systemic lupus erythematosus (SLE) prior to diagnosis 27 (IQR: 11, 55) months), 67% developed remission at 6 months (proportion 0.67; 95% CI 0.57, 0.76). Mycophenolate mofetil (MMF) was used in 45/96 (47%), CYC in 41/95 (43%) and other agents in 10/96 (10%). The choice of MMF as induction agent has increased in recent years. Among baseline characteristics, only histologic activity was found to have a significant association with remission, with active lesions more likely to remit than active/chronic and chronic lesions (AOR 6.5, 95% CI 1.44–29.39, p = 0.015). Based on Kaplan–Meier analysis, the 5-year renal survival rate without doubling serum creatinine was 73.8%. Compared to patients with complete remission, lower long-term renal survival rates were observed in patients with no remission (89.7 versus 43%, p = 0.001) and partial remission (89.7 versus 77.6%, p = 0.256). The cumulative rate of doubling serum creatinine, dialysis, relapse and death was 23%, 11%, 10% and 5%, respectively, at 48-month median follow up. Approximately two-thirds of patients with PLN develop remission in response to standard induction therapy. Remission was negatively associated with the presence of chronic changes in renal biopsy. Overall, MMF is the most commonly used agent to induce remission; however, with more severe disease CYC, is used more frequently. PLN is associated with significant long-term renal outcomes including a 26% cumulative rate of doubling of serum creatinine at 5 years. Initial remission predicts this long-term renal survival.

Introduction: One of the complications of diabetes mellitus (DM) is diabetic nephropathy (DN), which plays a significant role in the progression of end‐stage renal disease. Oxidative stress is implicated in DN pathogenesis, and genetic variations in antioxidant enzymes such as superoxide dismutase 2 (SOD2) and catalase (CAT) may contribute to the susceptibility. This study aimed to investigate the potential association between single nucleotide polymorphisms (SNPs) in antioxidant enzymes, specifically SOD2 rs4880 and CAT rs769217, and the risk of T2D and susceptibility to DN within the Saudi population.Methods: This case–control study included 150 participants, comprising 50 patients with T2D without DN (group 1), 50 patients with T2D with DN (group 2), and 50 healthy participants (group 3). The samples were genotyped using real‐time PCR for SOD2 rs4880 and CAT rs769217 SNPs. Sanger sequencing was used for validation. Statistical analyses were performed to explore associations between these SNPs and T2D with or without DN.Results: No significant difference was observed in CAT rs769217 expression between the groups. However, a significant difference was observed in SOD2 rs4880 expression between the healthy controls and patients with T2D with DN (p = .028). Furthermore, SOD2 rs4880 was associated with approximately threefold increased risk of DN in patients with T2D compared to that in healthy participants (odds ratio [OR] = 2.99 [1.31–6.83]). Validation through Sanger sequencing further confirmed these findings.Conclusions: The findings of this study provide evidence that SOD2 rs4880 SNP may contribute to inadequate defence by the antioxidant enzyme, SOD2, against DM‐induced oxidative stress and thus cause DN in Saudi patients with T2D. Therefore, SOD2 rs4880 may serve as a predictive marker to prevent the development and progression of DN in patients with T2D.
