Hemophagocytic lymphohistiocytosis (HLH) is an immune response syndrome characterized by excessive inflammation and tissue destruction. A limited number of cases involving HLH patients with concomitant multiple myeloma (MM), leading to significant mortality, have been documented, underscoring the importance of timely diagnosis. We present the case of a 78-year-old previously healthy male admitted to our hospital with a newly diagnosed MM. Subsequently, he was diagnosed with HLH and received treatment with anakinra, intravenous immunoglobulin, and dexamethasone. This case report highlights the unique aspect of being the first documented instance of myeloma-associated HLH treated with anakinra., Competing Interests: The authors declare no conflict of interest., (© 2024 The Author(s). eJHaem published by British Society for Haematology and John Wiley & Sons Ltd.)

Purpose: This study aimed to estimate the prevalence, contributory factors, and severity of medication errors associated with direct acting oral anticoagulants (DOACs)., Methods: A systematic review and meta-analysis were undertaken by searching 11 databases including Medline, Embase, and CINHAL between January 2008 and September 2020. The pooled prevalence of errors and predictive intervals were estimated using random-effects models using Stata software. Data related to error causation were synthesised according to Reason's accident causation model., Results: From the 5205 titles screened, 32 studies were included which were mostly based in hospitals and included DOAC treatment for thromboembolism and atrial fibrillation. The proportion of study population who experienced either prescription, administration, or dispensing error ranged from 5.3 to 37.3%. The pooled percentage of patients experiencing prescribing error was 20% (95% CI 15-25%; I 2  = 96%; 95% PrI 4-43%). Prescribing error constituted the majority of all error types with a pooled estimate of 78% (95%CI 73-82%; I 2  = 0) of all errors. The common reported causes were active failures including wrong drug, and dose for the indication. Mistakes such as non-consideration of renal function, and error-provoking conditions such as lack of knowledge were common contributing factors. Adverse events such as potentially fatal intracranial haemorrhage or patient deaths were linked to the errors but causality assessments were often missing., Conclusions: Despite their favourable safety profile, DOAC medication errors are common. There is a need to promote multidisciplinary working, guideline-adherence, training, and education of healthcare professionals, and the use of theory-based and technology-facilitated interventions to minimise errors and maximise the benefits of DOACs usage in all settings., Protocol: A protocol developed as per PRISMA-P guideline is registered under PROSPERO ID = CRD42019122996., (© 2021.

Introduction: It is well-established that clinical pharmacist-managed anticoagulation services achieve superior anticoagulation control, with a positive impact. At King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia, the structure of anticoagulation management is a pharmacist-managed specialty service. With the current COVID-19 situation, measures were taken to assure the continuity of patient care by establishing tele-pharmacy anticoagulation clinics. Materials and Methods: This was a prospective study with patients prescribed anticoagulation and followed up for 3 months. Since establishing the anticoagulation virtual clinic in March 2020, 270 patients were recruited in the study. The data collected included age, gender, comorbidities, indication for anticoagulation, intended duration of treatment, warfarin dose, testing of International Normalized Ratio (INR), INR target, range of INR values, time INR that was within the therapeutic range (TTR), and complications of therapy (bleeding and/or bruises). The patients were asked to complete the pharmacist satisfaction survey (PSS) after their consultation to assess patient satisfaction with the new virtual consultation system. Linguistic and cultural validation was conducted for the questionnaire. Results: A total of 270 patients were included in the study. The mean percentage of overall INR values in the range was 59.39% ± 32.84, and the mean time with the overall INR was within the therapeutic range 57.81% ± 32.08. Thirty-one percent of the sample had good anticoagulation control (time in therapeutic range >70%). The median satisfaction score was 32 (IQR 28-36) with a maximum score of 40. Conclusion: This is the first study to assess the tele-pharmacy anticoagulation clinic's efficiency and patient satisfaction in Saudi Arabia during the COVID-19 pandemic. This type of consultation was as effective as face-to-face consultations. The study also highlighted that though the reduction in the cost of care was not substantial, there was a significant increase in resource (clinical pharmacist) utilization as a result of this model. The adoption of tele-pharmacy resulted in time savings for the clinical pharmacists who can be utilized in many other improvement projects in adult ambulatory clinics to ensure the delivery of better quality and safe patient care., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Al Ammari, AlThiab, AlJohani, Sultana, Maklhafi, AlOnazi and Maringa.)

Objective: The present study examined pharmacists' knowledge and practices towards prescribed medications for hemodialysis patients. The impact of a pharmacist's current positions and years of experience on practices and knowledge was also assessed., Methods: A cross-sectional survey was distributed to pharmacists working at King Abdul-Aziz Medical City-Central Region over a period of 4 months from July to October in 2015., Results: Of the 85 approached pharmacists, 66 pharmacists completed the questionnaire, among which 45 (68.2%), 9 (13.6%), and 12 (18.2%) of them were outpatient hospital pharmacists, discharge counselling pharmacists, and pharmacy practice residents, respectively. In total, 47 (55.3%) of the pharmacists sought drug information resources for newly prescribed medications to hemodialysis patients. Among the surveyed pharmacists, around two-thirds of them (63.6%) were completely confident during counselling hemodialysis patients, while 32% were moderately confident, and only 4.5% were not confident. All of the participating pharmacists checked each patient's allergic status before dispensing hemodialysis medications. The majority of the outpatient hospital pharmacists (35; 77.8%), discharge pharmacists (8; 88.9%), and the pharmacy practice residents (11; 91.7%) agreed that oral ciprofloxacin should be given after dialysis session on the same dialysis days, while 18 (40%), 5 (55.6%), and 9 (75%) of the outpatient hospital pharmacists, discharge pharmacists, and pharmacy practice residents agreed that IV route is preferred for hemodialysis patients to administer epoetin alfa, respectively. Sixty-six percent of discharge pharmacists ( n = 6), 91.7% ( n = 11) of the pharmacy practice residents, and 55.6% ( n = 25) of the outpatient hospital pharmacists checked patient laboratory results prior to dispensing medications ( p = 0.001)., Conclusions: Despite the limited knowledge regarding some prescribed medications, most of the hospital pharmacists showed good practices toward dialysis patients.

Objectives: The study aimed to assess the mental health outcomes and associated factors among health care workers during COVID 19 in Saudi Arabia. Design, Setting, and Participants: We conducted a cross-sectional survey of health care workers from tertiary care and ministry of health Centers across the Central, Eastern, and Western regions of Saudi Arabia. There were 1,130 participants in the survey, and we collected demographic and mental health measurements from the participants. Primary Outcomes and Measures: The magnitude of symptoms of depression, anxiety, and insomnia was measured using the original version of 9-item patient health questionnaire (PHQ-9), the 7-item generalized anxiety disorder scale (GAD-7), and 7-item insomnia severity index (ISI). We use the multiple logistic regression analysis to identify the associated risk factors of individual outcomes. Results: The scores on the PHQ-9 showed that the largest proportion of health care workers (76.93%) experienced only normal to mild depression (50.83 and 26.1%, respectively). The scores on the GAD-7 showed that the largest proportion of health care workers (78.88%) experienced minimal to mild anxiety (50.41 and 28.47%, respectively). The scores on the ISI showed that the largest proportion of health care workers (85.83%) experienced absence to subthreshold insomnia (57.08 and 28.75%, respectively). The risk factors for depression in health care workers were Saudi, living with family, working from an isolated room at home and frontline worker. For anxiety, being female was risk factor and for insomnia, being frontline worker was risk factor. Conclusion: It was observed that the symptoms of depression, anxiety, and insomnia were reported in a lower proportion of health care workers in our study. The participants who were female, frontline workers, Saudi, living with family, and working from home in isolated rooms were predisposed to developing psychological disorders., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Al Ammari, Sultana, Thomas, Al Swaidan and Al Harthi.)

Colistin-induced nephrotoxicity is a well-known major adverse event, which may occur within seven days [early acute kidney injury (AKI)] with a high mortality rate of 70% or after seven days (late AKI). The main objective of this retrospective study is to assess the severity and associated risk factors for the development of colistin-related nephrotoxicity. An observational retrospective cohort study was conducted over 12 months (January-December 2017). All patients with a baseline normal renal function, who received intravenous colistin for >72 h, were included. Nephrotoxicity was defined using the RIFLE criteria (Risk, Injury, Failure, Loss, and End-stage renal disease). The demographic and clinical variables were retrieved from the hospital's electronic medical record system and compiled in an electronic database. All the statistical analysis was carried out by SAS JMP from SAS Institute Inc., Cary, NC. Seventy patients met the inclusion criteria. Colistin-induced nephrotoxicity occurred in 45.71% of the patients, of whom 40.6% were at Risk, 21.9% at Injury, and 37.5% at Failure according to RIFLE criteria. In patients who developed AKI, the average total colistin dose received before AKI was 4.4 mg/kg/day. More than half of the AKI group (53.13%) received an inappropriate total dose of colistin. Age, 65 years and older, was significantly associated with a high risk of nephrotoxicity (P <0.05), which developed within 6.8 ± 0.44 days from receiving a colistin dose. Clinical pharmacy services were consulted in 28.13% of the cases, and the dose was adjusted in 37.5% of the patients. Colistin nephrotoxicity is common and is associated more with older age group and inappropriate dosing.

Warfarin is a frequently prescribed oral anticoagulant with a narrow therapeutic index, requiring careful dosing and monitoring. However, patients respond with significant inter-individual variability in terms of the dose and responsiveness of warfarin, attributed to genetic polymorphisms within the genes responsible for the pharmacokinetics and pharmacodynamics of warfarin. Extensive warfarin pharmacogenetic studies have been conducted, including studies resulting in genotype-guided dosing guidelines, but few large scale studies have been conducted with the Saudi population. In this study, we report the study design and baseline characteristics of the Saudi WArfarin Pharmacogenomics (SWAP) cohort, as well as the association of the VKORC1 promoter variants with the warfarin dose and the time to a stable INR. In the 936 Saudi patients recruited in the SWAP study, the minor allele C of rs9923231 was significantly associated with a 8.45 mg higher weekly warfarin dose (p value = 4.0 × 10 -46 ), as well as with a significant delay in achieving a stable INR level. The addition of the rs9923231 status to the model, containing all the significant clinical variables, doubled the warfarin dose explained variance to 31%. The SWAP cohort represents a valuable resource for future research with the objective of identifying rare and prevalent genetic variants, which can be incorporated in personalized anticoagulation therapy for the Saudi population.

Objective: The primary objective was to assess the satisfaction of patients undergoing hemodialysis regarding counseling services provided by pharmacists. The secondary objectives were to compare the effect of years on dialysis and the presence of comorbidities on patient satisfaction., Methods: A total of 138 patients were included in the study, and all demographic and clinical variables were retrieved from the dialysis unit records of King Abdulaziz Medical City over a period of 4 months from July to October 2015. Chi-square test and Fisher's exact test were used for group comparisons at a significance level of 0.05. Results : Most patients aged between 51 and 75 years and had been on dialysis for 1 to 5 years; 94.9% of them had comorbidities. The overall satisfaction of patients toward pharmacy services was excellent (77.5%), and approximately 38.4% of patients thought that pharmacists were providing clear information about their prescribed medications. In addition, 55.8 % of the patients did not know that hemodialysis could affect the efficacy of their medications. Conclusions: Patients undergoing hemodialysis were somewhat satisfied with the counseling provided by the pharmacist. Moreover, there is a need for educational programs for patients undergoing hemodialysis that would increase awareness among hospital pharmacists to improve patients' medication knowledge., Competing Interests: We declare that we have no competing interests.

Background: There is limited data that investigates the national rates of drug-resistant tuberculosis (TB) in Saudi Arabia.This study aimed to estimate the rates of multi-drug-resistant tuberculosis (MDR-TB), rifampicin-resistant tuberculosis (RR-TB), and monoresistance (MR) in Saudi Arabia., Methods: A retrospective cohort study was conducted on all TB cases reported to the National TB Control and Prevention Program (NTCPP) registry at the Saudi Ministry of Health between January 1, 2014 and December 31, 2015. A total of 2098 TB patients with positive TB cultures were included in the study. Subgroup analyses and multivariate binary logistic regression models were performed with IBM SPSS 23.0., Results: Of the total TB cases, 4.4% (95% CI: 3.59%-5.40%) were found to have MDR-TB. The rates of MR were 3.8% (95% CI: 2.99%-4.67%) for ethambutol, 5.4% (95% CI: 4.50%-6.49%) for pyrazinamide, 10.2% (95% CI: 5.89%-11.52%) for isoniazid, 11% (95% CI: 9.70%-12.43%) for streptomycin, and 5.9% (95% CI: 4.90%-6.96%) for rifampicin. The high rates of MDR and RR-TB were found among the younger age group, female gender, and those who had a previous history of TB. We also discovered that renal failure tends to increase the risk of rifampicin resistance., Conclusions: National TB data in Saudi Arabia shows that the rate of MDR-TB was similar to the global rate reported by the World Health Organization (WHO). It is a relatively high rate as compared to Western countries. The proportion of MDR/RR-TB patients tends to be higher in the younger age group, female gender, and in patients with a previous history of TB treatment. Effective strategies for prevention of all multi-drug-resistant TB cases are warranted., Competing Interests: The study received ethical approval from the Institutional Review Board (IRB) at Saudi Ministry of Health and King Abdullah International Medical Research Center.Not applicable.The authors declare that they have no competing interests.

Objectives: To delineate the clinical features and outcomes of dengue infection and to guide clinician of early diagnosis and identification of risks factors for dengue hemorrhagic fever. Methods: This study is a retrospective cross-sectional. Clinical records of 567 patients with a confirmed diagnosis of dengue infection, admitted to a single hospital in Jeddah, Saudi Arabia, between January 2010 and  June 2014 were reviewed.  Results: Dengue infection was most common in adult males. Sixty-eight percent of infections were in Saudi nationals. In addition to the diagnostic clinical features, leucopenia and thrombocytopenia were typical of dengue infection. Approximately 4.1% of adult patients and 7.1% of pediatric patients developed dengue hemorrhagic fever (DHF). Abdominal pain and vomiting were more common in patients developing DHF. Mean platelet count was lower in adult, but not pediatric patients developing DHF. Peak alanine aminotransferase (ALT) was higher in adult and pediatric patients developing DHF. Three patients died, 2 of them developed DHF. Ninety-eight percent of adult patients and 92% of pediatric patients made a full recovery. Conclusions:   Dengue infection is common in Jeddah.  Abdominal pain and vomiting, thrombocytopenia, and elevated ALT are typical of severe infection, which is more likely to be associated with significant morbidity and mortality.

Background: Vaso-occlusive crisis (VOC) is one of the acute complications of sickle-cell disease (SCD). Treatment mainly relies on hydration and pain control by analgesics. The specific aim of this study was to assess potential health outcomes within the first 72 h of admission between intermittent and patient-controlled analgesia (PCA) by opioids among VOC patients., Methods: A retrospective chart review study was conducted to determine SCD patients with VOC. Using the hospital electronic system, the following data were collected: patient's age, gender, blood pressure, heart rate, respiratory rate, oxygen saturation, and pain score on admission and daily for 3 days as well as the cumulative opioid analgesic dose for 72 h which is reported as morphine equivalent., Results: One hundred and seventeen patients were screened over a period of 5 years. Of those, 99 (84.6%) met the study inclusion criteria, and 18 patients (15.4%) were excluded from the study. During the first 72 h of admission, a significant reduction in pain score was observed in patients on intermittent intravenous (IV) administration compared to those in the PCA group ( P < 0.0004) where the mean pain scores were 3 and 5, respectively. The total amount of morphine administered over 72 h of admission was significantly higher in PCA group (777 ± 175 mg) as compared to the intermittent IV administration group (149 ± 74 mg) ( P < 0.000003). Clinically significant hypotension or respiratory depression was not observed in both groups over the 72 h of admission., Conclusion: During the first 72 h of admission, intermittent IV administration of morphine was more effective than PCA infusion in pain control., Competing Interests: There are no conflicts of interest.

An association between multiple myeloma (MM) and solid tumours has been previously described. 1 Furthermore, autoimmune disorders can precede plasma cell dyscrasias, and the pathogenesis of MM maybe linked to chronic immune stimulation. 2 We describe a case of concomitant MM and gastric adenocarcinoma preceded by Evan's syndrome. A previously healthy woman presented to the emergency room with symptomatic anaemia. Her initial workup was compatible with autoimmune haemolytic anaemia and monoclonal gammopathy of undetermined significance. On progression of the anaemia and development of thrombocytopenia, she was diagnosed with Evan's syndrome. Two months later, she presented with severe back pain and her MRI revealed L4-5 vertebral collapse. The clinical picture was compatible with MM. Occult blood was repeatedly positive in stools, and she underwent oesophagogastroduodenoscopy and was found to have gastric adenocarcinoma. The patient refused surgical resection of the adenocarcinoma and refused active treatment for MM., Competing Interests: Conflicts of Interest: None declared., (2016 BMJ Publishing Group Ltd.)

Objectives: To assess the proportion of critical errors committed while demonstrating the inhaler technique in hospitalized patients diagnosed with asthma and chronic obstructive pulmonary disease (COPD). , Methods: This cross-sectional observational study was conducted in 47 asthmatic and COPD patients using inhaler devices. The study took place at King Abdulaziz Medical City, Riyadh, Saudi Arabia between September and December 2013. Two pharmacists independently assessed inhaler technique with a validated checklist. , Results: Seventy percent of patients made at least one critical error while demonstrating their inhaler technique, and the mean number of critical errors per patient was 1.6. Most patients used metered dose inhaler (MDI), and 73% of MDI users and 92% of dry powder inhaler users committed at least one critical error.  , Conclusion: Inhaler technique in hospitalized Saudi patients was inadequate. Health care professionals should understand the importance of reassessing and educating patients on a regular basis for inhaler technique, recommend the use of a spacer when needed, and regularly assess and update their own inhaler technique skills.

Background: Little is known about the perceived attitude, barriers and facilitators of Saudi Pharmacists about practice based research. We aimed to measure the attitude, barriers, and facilitators of Saudi hospital pharmacists towards pharmacy practice research., Method: A cross-sectional survey of hospital pharmacists (n = 216) working in King Abdulaziz Medical Cities in Central, Eastern and Western region hospitals was conducted during first week of September, 2013. The survey instrument comprised of six different sections that explored pharmacists previous participation in research, items regarding attitude, perception and willingness to participate, motivators, barriers, different areas of interest for doing research and patient demographics. Quantitative data collected was initially explored using frequency distribution, and descriptive analysis was carried out. Mann-Whitney U and independent samples t-test were used to explore the differences between the study variables., Results: One hundred and eighty two pharmacists completed the survey yielding a response rate of 84 %. Fifty-nine percent of pharmacists have prior research experience. Pharmacists with research experience were more confident in reading and evaluating research papers (p = 0.01), and designing a research study (p = 0.001). Pharmacists with previous research experience were also more likely to participate in future research opportunities (p = 0.004) and were confident in their research skills (p = 0.003). No differences were observed about the perceived value of research, facilitators and barriers to participate in research, between pharmacists with prior research experience and pharmacists who have no prior experience to do research., Conclusion: Pharmacists in this study were unanimous about the importance of research but showed considerable differences in their confidence to carry out research. There is a need to provide additional support to enable Saudi pharmacists in conducting practice based research.
