Pharmacy practice in hospital settings in GCC countries: Pharmacists' medication therapy monitoring activities.

Purpose: Our study aims to provide an overview of medication therapy monitoring practices carried out by pharmacists in hospitals across the Gulf Cooperation Council (GCC) countries. Methods: This is a cross-sectional questionnaire-based study of hospitals located in the GCC. Questions were adopted from the American Society of Health-System Pharmacists (ASHP) national survey. Frequency analyses were used to examine the number and percentages of specific responses to the survey questions. Results: A total of 64 hospitals participated in this survey, reflecting an overall response rate of 52.0%. Almost half of participating hospitals (48.4%) were from Saudi Arabia. Among the 64 participating hospitals, 54.7% monitored their patients daily, 40.6% assigned pharmacists to patient care units for at least eight hours per day, and 42.2% held pharmacists accountable for medication-related outcomes. Moreover, the criteria used to identify patients requiring monitoring, 35.9% relied on the list of high-risk medications, 26.5% relied on specific medical services, 21.9% relied on directions from the hospital committee, and 17.2% relied on lab abnormalities. The most frequently utilized method for monitoring adverse drug events (ADEs) was through notifications from nurses or physicians, observed in 60.9% of participating hospitals. Conclusion: The survey emphasizes the need for hospitals in the GCC to promote increased pharmacist accountability for medication-related outcomes, explore technological solutions to enhance monitoring efficiency and extend the presence of pharmacists in patient care units beyond the current level.

Pharmacy practice in hospital settings in GCC countries: Dispensing and administration.

Purpose: To outline dispensing and administration practices in hospital pharmacy across the Gulf Cooperation Councils (GCC) countries' hospitals. Paucity of data in appraising hospital pharmacy practice in GCC regions motivated us to conduct this study. Methods: A modified survey questionnaire was prepared from the American Society of Health-System Pharmacist (ASHP) survey questions. Three major domains of questions for general characteristics of the medication use process for dispensing and administration were identified. These were, (1) medication distribution system, and medication distribution technology, (2) technology used to compound sterile preparations, compounding I.V. medication and method of compounding nutrition support preparations, (3) medication administration practices, medication orders, medication administration records (MARs), and technician activities. A list of hospitals was obtained from the Ministry of Health of the targeted GCC countries. A secure invitation link containing a survey questionnaire was sent to the participants directly. Results: Sixty-four hospitals responded to this survey. The overall response rate was 52%. Most surveyed hospitals have centralized inpatient medications distribution system (75.0%). About 37.5% of hospitals used automated dispensing cabinets (ADCs) in their patient care areas. Compounding sterile preparations in the pharmacy, barcode verification technology, workflow management technology, and robotic technology were used by 17.2%, 15.6%, and 4.7% of hospitals, respectively. In using safety technology for medication administration, almost all hospitals have partially or completely implemented an electronic health record (EHR). About 40.6% of hospitals used electronic medication administration records (e-MARs), 20.3% used bar-code-assisted medication administration (BCMA), and 35.9% used smart infusion pumps. Conclusion: The results of this survey revealed an opportunity to improve the medication use management process on dispensing and administration practices in hospitals in GCC countries.

Pharmacy practice in hospital settings in GCC countries: Prescribing and transcribing.

PURPOSE: To outline hospital pharmacy practices across the Gulf Cooperation Councils (GCC) countries' hospitals. METHODS: A modified survey questionnaire was prepared from the original 2019 American Society of Health-System Pharmacist (ASHP) survey questions. Survey details were discussed with some pharmacy directors for clarity and relevance. A list of hospitals were obtained from the Ministry of Health of each of the targeted GCC countries. A secure invitation link containing a survey questionnaire was sent to the participants directly. RESULTS: Sixty four hospitals responded to this survey. The overall response rate was 52%. About 47% of the surveyed hospitals considered their drug formularies as closed, and strict. Additionally, only 44% of hospitals compare the effectiveness of products, when taking formulary decisions for drug inclusion. Forty-four percent of hospitals have computerized prescriber order entry (CPOE / EHR) system functionality for formulary system management. At about 39.1% hospitals, pharmacists have the responsibility for managing medication therapies, majority were engaged in providing anticoagulation therapies. About 61% of hospital pharmacies in GCC countries receive medication orders electronically, through CPOE/EHR. Majority (66%) of the hospitals in GCC countries have an active Antimicrobial Stewardship Program (ASP) while only 40% of pharmacists have a key role in providing clinical support. About 57.8% of hospital pharmacy directors reported that pharmacists do not provide ambulatory care clinical pharmacy services in their hospitals. CONCLUSION: In GCC countries' hospitals, there are major areas for improvement to patient care of which pharmacists are uniquely qualified as the medication experts to have the most meaningful outcomes in all of the domains of safe medication use, medication therapy management, antimicrobial stewardship program and participation in outpatient clinics.

A P&T Committee's Transition to a Complete Electronic Meeting System-A Multisite Institution Experience.

PURPOSE: In the last few decades, changes to formulary management processes have taken place in institutions with closed formulary systems. However, many P&T committees continued to operate using traditional paper-based systems. Paper-based systems have many limitations, including confidentiality, efficiency, open voting, and paper wastage. This becomes more challenging when dealing with a multisite P&T committee that handles formulary matters across the whole health care system. In this paper, we discuss the implementation of the first paperless, completely electronic, Web-based formulary management system across a large health care system in the Middle East. SUMMARY: We describe the transitioning of a multisite P&T committee in a large tertiary care institution from a paper-based to an all-electronic system. The challenges and limitations of running a multisite P&T committee utilizing a paper system are discussed. The design and development of a Web-based committee floor management application that can be used from notebooks, tablets, and hand-held devices is described. Implementation of a flexible, interactive, easy-to-use, and efficient electronic formulary management system is explained in detail. CONCLUSION: The development of an electronic P&T committee meeting system that encompasses electronic document sharing, voting, and communication could help multisite health care systems unify their formularies across multiple sites. Our experience might not be generalizable to all institutions because this depends heavily on system features, existing processes and workflow, and implementation across different sites.

Saudi National Clinical Practice Guidelines for Management of Adult Systemic Lupus Erythematosus.

OBJECTIVE: To provide evidence-based clinical practice recommendations for managing Systemic Lupus Erythematosus (SLE) in Saudi Arabia. METHODS: This EULAR-adapted national guideline in which a multidisciplinary task force utilized the modified Delphi method to develop 31 clinical key questions. A systematic literature review was conducted to update the evidence since the EULAR publication. After reaching a consensus agreement, two rounds of voting and group discussion were conducted to generate consolidated recommendations/statements. RESULTS: A significant number of patients in Saudi Arabia experience delays in accessing rheumatologists, highlighting the significance of timely referral to SLE specialists or rheumatologists to ensure accurate diagnosis and prompt treatment. The primary goal of Glucocorticoid (GC) therapy in SLE patients is to establish disease control with a minimum dose and duration. Steroid-sparing agent utilization facilitates steroid-sparing goals. Hydroxychloroquine is recommended for all SLE patients, though physicians must carefully monitor toxicity and prioritize regular medication adherence assessment. SLE management during pregnancy starts from preconception time by assessing disease activity, major organ involvement, hypercoagulability status, and concomitant diseases that may negatively impact maternal and fetal outcomes. Multidisciplinary care with close monitoring may optimize both maternal and fetal outcomes. For patients with antiphospholipid antibodies, low-dose aspirin prophylaxis is recommended. Also, Long-term anticoagulant medications are fundamental to prevent secondary antiphospholipid syndrome due to high thrombosis recurrence. CONCLUSION: This Saudi National Clinical Practice guidelines for SLE management provide evidence-based recommendations and guidance for healthcare providers in Saudi Arabia who are managing patients with SLE. These guidelines will help to standardize healthcare service, improve provider education, and perhaps lead to better treatment outcomes for SLE patients.

Hospital pharmacy practice in Saudi Arabia: Drug monitoring and patient education in the Riyadh region.

BACKGROUND: The purpose of this national survey is to evaluate hospital pharmacy practice in the Riyadh region of Saudi Arabia. The results of the survey pertaining to the monitoring and patient education of the medication use process were presented. METHODS: We have invited pharmacy directors from all 48 hospitals in the Riyadh region to participate in a modified-American Society of Health-System Pharmacists (ASHP) survey questionnaire. The survey was conducted using similar methods to those of the ASHP surveys. RESULTS: The response rate was 60.4% (29/48). Most hospitals (23, 79%) had pharmacists regularly monitor medication therapy for patients. Of these hospitals, 61% had pharmacists monitoring medication therapy daily for less than 26% of patients, 17% monitored 26-50% of patients and 22% monitored more than half of patients daily. In 41% of hospitals, pharmacists routinely monitored serum medication concentrations or their surrogate markers; 27% gave pharmacists the authority to order initial serum medication concentrations, and 40% allowed pharmacists to adjust dosages. Pharmacists routinely documented their medication therapy monitoring activities in 52% of hospitals. Overall, 74% of hospitals had an adverse drug event (ADE) reporting system, 59% had a multidisciplinary committee responsible for reviewing ADEs, and 63% had a medication safety committee. Complete electronic medical record (EMR) systems were available in 15% of hospitals and 81% had a partial EMR system. The primary responsibility for performing patient medication education lays with nursing (37%), pharmacy (37%), or was a shared responsibility (26%). In 44% of hospitals, pharmacists provided medication education to half or more inpatients and in a third of hospitals, pharmacists gave medication education to 26% or more of patients at discharge. CONCLUSION: Hospital pharmacists in the Riyadh region are actively engaged in monitoring medication therapy and providing patient medication education, although there is considerable opportunity for further involvement.

Evidence-based Management of Major Bleeding in Patients Receiving Direct Oral Anticoagulants: An Updated Narrative Review on the Role of Specific Reversal Agents.

The indications of direct oral anticoagulants (DOACs) have expanded over the past 15 years. DOACs are effective and safe oral anticoagulants associated with lower bleeding risks and mortality than vitamin K antagonists. However, DOAC users are prone to a considerable bleeding risk, which can occur at critical sites or lead to severe life-threatening conditions. Recent statistics indicated that major bleeding occurs in up to 6.62 DOAC users per 100 treatment years. With the increased use of DOACs in clinical practice, DOAC-associated major bleeding is expected to be encountered more frequently in the emergency department. The current international guidelines recommend specific reversal agents for the management of DOAC users with severe bleeding to reverse the anticoagulant effect and restore normal hemostasis. An individualized assessment was incorporated in specific clinical situations to guide the decision pathway of major bleeding management. However, specific reversal agents are unavailable or have limited availability in many countries, which is expected to negatively impact the clinical outcomes of DOAC-associated major bleeding. Limited real-world evidence is available from these countries regarding the clinical outcomes of patients with DOAC-associated major bleeding. This narrative review provided an updated assessment of the evidence-based approaches for the management of major bleeding in DOAC users. We also explored the clinical outcomes of patients with major bleeding from clinical settings where specific reversal agents are unavailable.

Saudi consensus guidance for the management of inflammatory bowel disease during pregnancy.

ABSTRACT: The management of inflammatory bowel disease (IBD) in pregnant women is challenging and must be addressed on a patient-by-patient basis. Optimal patient management requires a multidisciplinary team and clear evidence-based recommendations that cater to this subset of patients. In this article, we provide concise guidelines and clinical care pathway for the management of IBD in pregnant women. Our recommendations were developed by a multidisciplinary working group that includes experts from the Saudi Ministry of Health in collaboration with the Saudi Gastroenterology Association and the Saudi Society of Clinical Pharmacology. All recommendations are based on up-to-date information following an extensive literature review. A total of 23 evidence-based expert opinion recommendations for the management of IBD in pregnant women are herein provided.

Assessment of foetal risk associated with 93 non-US-FDA approved medications during pregnancy.

Health care practitioners utilize the United States-Food and Drug Administration (US-FDA) pregnancy categorization (A, B, C, D, X) for making decision on the appropriateness of certain medications during pregnancy. Many non US-FDA approved medications are registered and marketed in Saudi Arabia. However, these medications do not have an assigned pregnancy risk categorization like those approved in the US. The objective of this review is to evaluate, report, and categorize the foetal risk associated with non-US-FDA approved medications registered by the Saudi Food and Drug Authority (S-FDA) according to the US-FDA pregnancy risk categorization system. We identified 109 non-US-FDA approved medications in the Saudi National Formulary (SNF) as of October 2007. We searched for data on functional or anatomical birth defects or embryocidal-associated risk using different databases and references. An algorithm for risk assessment was used to determine a pregnancy risk category for each medication. Out of 93 eligible medications, 73% were assigned category risk C, 10 medications (11%) were assigned category risk D, and 12 medications (13%) were assigned category risk B. Only three medications were judged to be safe during pregnancy based on the available evidence and were assigned category risk A. Inconsistencies in defining and reporting the foetal risk category among different drug regulatory authorities could create confusion and affect prescribing. We believe that standardization and inclusion of this information in the medication package insert is extremely important to all health care practitioners.

Hospital pharmacy practice in Saudi Arabia: Prescribing and transcribing in the Riyadh region.

PURPOSE: The purpose of this survey is to outline pharmacy services in hospitals on a regional level in the Kingdom of Saudi Arabia. METHODS: A modified-American Society of Health-System Pharmacists (ASHP) survey questionnaire as pertinent to Saudi Arabia was used to conduct a national survey. After discussing with the pharmacy directors of 48 hospitals in the Riyadh region over the phone on the survey's purpose, the questionnaires were personally delivered and collected upon completion. The hospital lists were drawn from the Ministry of Health hospital database. RESULTS: Twenty-nine hospitals participated in the survey giving a response rate of 60.4%. Approximately 60% of the hospitals which participated in the survey required prior approval for the use of non-formulary medications. About 83.3% of hospitals reviewed compliance with clinical practice guidelines and 72.7% hospitals reported that pharmacists are also actively involved in these activities. Pharmacists in more than 95% of hospitals provided consultations on drug information. A staff pharmacist routinely answering questions was the most frequently cited (74.1%) method by which objective drug information was provided to prescribers. Electronic drug information resources were available in 77.7% of hospitals, although internet use is not widely available to hospital pharmacists, with only 58.6% of hospitals providing pharmacist access to the internet. About, 34.5% of hospitals had computerized prescriber order entry (CPOE) systems with clinical decision-support systems (CDSSs) and 51.9% of the hospitals had electronic medical record (EMR) system. CONCLUSION: Hospital pharmacists are increasingly using electronic technologies to improve prescribing and transcribing of medications in Saudi Arabia.

Hospital pharmacy practice in Saudi Arabia: Dispensing and administration in the Riyadh region.

BACKGROUND: There is very little published data assessing hospital pharmacy practice in Saudi Arabia. Hence, a comprehensive survey has been undertaken to evaluate hospital pharmacy services of the Kingdom of Saudi Arabia. Recently, we published the survey results on the prescribing and transcribing steps of the medication use process. This paper focuses on dispensing and administration. METHODS: A modified-American Society of Health-System Pharmacists (ASHP) survey questionnaire was personally delivered to the pharmacy directors of 48 hospitals in the Riyadh region. Three attempted follow-ups were made within 3 months to non-responders and the surveys were collected upon completion. The survey was conducted using similar methods to those of the ASHP surveys. RESULTS: Twenty-nine hospitals participated in the survey with a response rate of 60.4%. Centralized distribution (74%) is the most commonly used model for inpatient pharmacies. Overall, 21% of hospitals routinely use bar coding technology in medication dispensing. None of the hospitals are using a robotic distribution system to automate the dispensing of unit doses. Automated dispensing cabinets (ADCs) are used by 21% of hospitals as part of their decentralized distribution model. Sixty-one percent of hospital pharmacies have IV admixture preparation area in their facility. In the use of safety technology for medication administration, only one third of hospitals are using electronic medication administration records (eMARs), 7.4% had bar-code-assisted medication administration (BCMA) and 12% had smart infusion pumps. CONCLUSION: Hospital pharmacies in the Riyadh region are fairly well developed in providing dispensing and administration services. Further improvement can be achieved by increasing the use of new technologies such as bar-code technology, unit dose drug distribution systems, pharmacy-based IV admixture services, smart infusion pumps, and automated medication distribution.

Tacrolimus-Induced Neurotoxicity in Early Post-Liver Transplant Saudi Patients: Incidence and Risk Factors.

BACKGROUND Tacrolimus is a calcineurin inhibitor (CNI) commonly used as an immunosuppressant to prevent the rejection of organ transplants. After liver transplantation, it can cause early neurological complications, known as early calcineurin inhibitor-induced neurotoxicity (ECIIN). Its management requires CNI withdrawal, a measure that can affect post-transplant outcomes, primarily allograft rejection. In addition, it can negatively impact the quality of life. The incidence and risk factor of ECIIN has not been reported in the Saudi population. We investigated the incidence and risk factors of ECIIN after liver transplant in Saudi patients. We also looked at the length of stay in the Intensive Care Unit, hospital, and 30-day mortality as secondary endpoints. MATERIAL AND METHODS This was a retrospective cohort study of adult patients on tacrolimus with mild, moderate, or severe neurological events within the first month after liver transplantation at a single center of patients who meet the inclusion criteria and were over age 14 years. A total of 338 patients were included in the analysis, and the sample size was calculated based on a pilot study. RESULTS Among 338 liver transplantation patients, 63 patients (19%) developed ECIIN. Forty-eight percent of patients had seizures, 23% had agitation, 21% had psychosis, 10% had severe tremors, 13% had confusion, and 6% developed coma. The median time of the incident to develop ECIIN was 9 (IQR: 5-13.5) days after transplant. Thirty-eight patients were managed by switching to cyclosporine, 12 required a reduction in the dose, and 3 were managed temporarily by discontinuing therapy. Autoimmune hepatitis as an underlying liver disease was one of the statistically significant risk factors (P=0.0311). The median length of hospital stay was 31 (IQR: 21-75.5) days, ICU length of stay was 10 (IQR: 5-20.5) days, and 8 patients died within 30 days after transplant. CONCLUSIONS The incidence of ECIIN in Saud Arabia was similar to that reported in other populations with similar risk factors. Electrolyte imbalance, mainly hyponatremia, was significantly associated with developing ECIIN. Therefore, ECIIN may potentially increase hospital and ICU length of stay.

Saudi Arabia consensus guidance for the diagnosis and management of adults with inflammatory bowel disease.

Optimal management of inflammatory bowel disease (IBD) relies on a clear understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This article provides concise guidelines for the management of IBD in adults, based on the most up-to-date information at the time of writing and will be regularly updated. These guidelines were developed by the Saudi Ministry of Health in collaboration with the Saudi Gastroenterology Association and the Saudi Society of Clinical Pharmacy. After an extensive literature review, 78 evidence-and expert opinion-based recommendations for diagnosing and treating ulcerative colitis and Crohn's disease in adults were proposed and further refined by a voting process. The consensus guidelines include the finally agreed on statements with their level of evidence covering different aspects of IBD diagnosis and treatment.

Saudi consensus recommendations on the management of multiple sclerosis: MS management in children and adolescents.

Multiple sclerosis (MS) most commonly presents in young adults, although 3-5% of patients develop MS prior to the age of 18 years. The new and comprehensive consensus for the management of MS in Saudi Arabia includes recommendations for the management of MS and other CNS inflammatory demyelinating disorders in pediatric and adolescent patients. This article summarizes the key recommendations for the diagnosis and management of these disorders in young patients. Pediatric and adult populations with MS differ in their presentation and clinical course. Careful differential diagnosis is important to exclude alternative diagnoses such as acute disseminated encephalomyelitis (ADEM) or neuromyelitis optica spectrum disorders (NMOSD). The diagnosis of MS in a pediatric/adolescent patient is based on the 2017 McDonald diagnostic criteria, as in adults, once the possibility of ADEM or NMOSD has been ruled out. Few data are available from randomized trials to support the use of a specific disease-modifying therapy (DMT) in this population. Interferons and glatiramer acetate are preferred initial choices for DMTs based on observational evidence, with the requirement of a switch to a more effective DMT if breakthrough MS activity occurs.

Saudi consensus recommendations on the management of Neuromyelitis Optica Spectrum Disorders (NMOSD).

This article focuses on the diagnosis and management of neuromyelitis optica spectrum disorder (NMOSD). NMOSD is an autoimmune, demyelinating condition characterized by inflammation of the optic nerve and/or the spinal cord, with symptoms that can range from mild impairment of movement to paralysis. The newly approved diagnostic criteria have improved the accuracy of NMOSD diagnosis. The management of NMOSD is under major revolution due to the many new therapeutic options. The role of the antibodies directed at aquaporin-4 (AQP4) has materialized as a biomarker for NMOSD. Several new treatments that target variable aspects in immunopathology such as IL-6, complement, or depletion of B cells are emerging. The management of AQP4-negative patients remains challenging.

Sirolimus induced dyslipidemia in tacrolimus based vs. tacrolimus free immunosuppressive regimens in renal transplant recipients.

BACKGROUND: Sirolimus is a potent immunosuppressive drug that has been shown to decrease the incidence of rejection post renal transplantation. Dyslipidemia is a well recognized side effect of sirolimus therapy, which may have an impact on patient survival and post-transplant cardiac morbidity and mortality. It is unknown whether sirolimus-induced dyslipidemia is aggravated by concomitant use of tacrolimus which may also affect lipid profile. To compare sirolimus induced dyslipidemia in tacrolimus based vs. tacrolimus free regimens in renal transplant recipients. MATERIAL/METHODS: Patients who received sirolimus post kidney transplantation for at least nine sequential months were included in our retrospective study. Forty-eight renal transplant recipients were divided into 2 groups based on the immunosuppressive regimen; Group 1 received prednisone, sirolimus and mycophenolate mofetil, while Group 2 received prednisone, sirolimus, mycophanolate mofetil and tacrolimus. Lipid profile was assessed pre-transplantation and at one, three, six and nine months post sirolimus therapy. RESULTS: Both groups showed significant but comparable elevation in total cholesterol, LDL-C and triglycerides with sirolimus therapy. The elevation was evident starting from the first month of sirolimus administration and remained to the ninth month at the end of the follow up period. At first month, mean triglycerides was 2.68 and 2.6 mmol/L (P>0.1) and mean total cholesterol was 6.3 and 5.7 mmol/L in group 1 and 2 (P>0.1); respectively. By the ninth month, triglycerides level was 2.6 and 3.9 mmol/L (P>0.1) while mean total cholesterol level was 6.2 and 6.1 mmol/L (P>0.1) in group 1 and 2 respectively. Lipid-lowering agents and total steroids dose were similar in both groups. CONCLUSIONS: Hypercholesterolemia and hypertriglyceridemia secondary to sirolimus therapy is independent from concomitant tacrolimus use. Lipid-profile should be monitored in all renal transplant recipients receiving sirolimus as early as first month regardless of the immunosuppressive regimen used.

Cost-effectiveness of oral agents in relapsing-remitting multiple sclerosis compared to interferon-based therapy in Saudi Arabia.

BACKGROUND: Promising clinical and humanistic outcomes are associated with the use of new oral agents in the treatment of relapsing-remitting multiple sclerosis (RRMS). This is the first cost-effectiveness study comparing these medications in Saudi Arabia. OBJECTIVES: We aimed to compare the cost-effectiveness of fingolimod, teriflunomide, dimethyl fumarate, and interferon (IFN)-b1a products (Avonex and Rebif) as first-line therapies in the treatment of patients with RRMS from a Saudi payer perspective. DESIGN: Cohort Simulation Model (Markov Model). SETTING: Tertiary care hospital. METHODS: A hypothetical cohort of 1000 RRMS Saudi patients was assumed to enter a Markov model model with a time horizon of 20 years and an annual cycle length. The model was developed based on an expanded disability status scale (EDSS) to evaluate the cost-effectiveness of the five disease-modifying drugs (DMDs) from a healthcare system perspective. Data on EDSS progression and relapse rates were obtained from the literature; cost data were obtained from King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. Results were expressed as incremental cost-effectiveness ratios (ICERs) and net monetary benefits (NMB) in Saudi Riyals and converted to equivalent $US. The base-case willingness-to-pay (WTP) threshold was assumed to be $100000 (SAR375000). One-way sensitivity analysis and probabilistic sensitivity analysis were conducted to test the robustness of the model. MAIN OUTCOME MEASURES: ICERs and NMB. RESULTS: The base-case analysis results showed Rebif as the optimal therapy at a WTP threshold of $100000. Avonex had the lowest ICER value of $337282/QALY when compared to Rebif. One-way sensitivity analysis demonstrated that the results were sensitive to utility weights of health state three and four and the cost of Rebif. CONCLUSION: None of the DMDs were found to be cost-effective in the treatment of RRMS at a WTP threshold of $100000 in this analysis. The DMDs would only be cost-effective at a WTP above $300000. LIMITATIONS: The current analysis did not reflect the Saudi population preference in valuation of health states and did not consider the societal perspective in terms of cost.

Renal allograft loss as the result of polyomavirus interstitial nephritis after simultaneous kidney-pancreas transplantation: results with kidney retransplantation.

BACKGROUND: Polyomavirus (PV) infection in kidney transplant patients has been reported to cause interstitial nephritis and subsequent graft loss. The cornerstone of current therapy is a reduction in immunosuppression, which can subsequently lead to kidney allograft rejection. This dilemma becomes even more challenging in the setting of simultaneous kidney-pancreas transplantation, because a reduction in immunosuppression may result in rejection of the pancreas allograft. Antiviral therapy has not been shown to be clinically successful in decreasing the risk of graft loss secondary to PV infection. Furthermore, because of limited experience, the decision to perform retransplantation in patients who lost their primary kidney grafts to PV interstitial nephritis becomes a difficult one. METHODS: Retrospective review and case studies. RESULTS: We report two successful living donor kidney retransplants in simultaneous kidney-pancreas transplant patients who lost their first kidney grafts to PV infection. Both patients are receiving rimantadine therapy and performing well, with functioning kidney and pancreas grafts and no evidence of recurrent PV interstitial nephritis 22 and 37 months after retransplantation. CONCLUSIONS: Although follow-up is limited, our initial experience would indicate that graft loss secondary to PV interstitial nephritis is not an absolute contraindication for kidney retransplantation.
