COVID-19 versus applied infection control policies in a Major Transplant Center in Iran.

BACKGROUND: Since Shiraz Transplant Center is one of the major transplant centers in Iran and the Middle East, this study was conducted to evaluate outcomes of the applied policies on COVID-19 detection and management. METHODS: During 4 months from March to June 2020, patient's data diagnosed with the impression of COVID-19 were extracted and evaluated based on demographic and clinical features, along with the length of hospital stay and expenses. RESULTS: Our data demonstrated that a total of 190 individuals, with a median age of 58, were diagnosed with COVID-19 during the mentioned period. Among these, 21 patients had a positive PCR test and 56 patients had clinical symptoms in favor of COVID-19. Also, 113 (59%) patients were classified as mild based on clinical evidence and were treated on an outpatient basis. Furthermore, 81 out of 450 cases (18%) of the healthcare workers at our center had either PCR of clinical features in favor of COVID-19. The mortality rate of our study was 11% and diabetes mellitus, hypertension were considered risk factors for obtaining COVID-19 infection. The direct cost of treatment and management of patients with COVID-19 amounted to 2,067,730,919 IRR, which considering the 77 patients admitted to Gary Zone per capita direct cost of treatment each patient was 26,853,648 IRR. CONCLUSION: We demonstrated that the COVID-19 pandemic had a noticeable influence on our transplant center in aspects of delaying surgery and increased hospital costs and burden. However, by implanting proper protocols, we were able to was able to provide early detection for COVID-19 and apply necessary treatment and prevention protocols to safeguard the patients under its coverage, especially immunocompromised patients.

Immunogenicity of Inactivated SARS-CoV-2 Vaccine (BBIBP-CorV; Sinopharm) and Short-Term Clinical Outcomes in Vaccinated Solid Organ Transplant Recipients: A Prospective Cohort Study.

BackgroundImmunocompromised patients have lower seroconversion rate in response to COVID-19 vaccination. The aim of this study is to evaluate the humoral immune response with short-term clinical outcomes in solid organ transplant recipients vaccinated with SARS-CoV-2 vaccine (BBIBP-CorV; Sinopharm).MethodsThis prospective cohort was conducted from March to December 2021 in Abu Ali Sina hospital, Iran. All transplant recipients, older than 18 years were recruited. The patients received two doses of Sinopharm vaccine 4 weeks apart. Immunogenicity was evaluated through assessment of antibodies against the receptor-binding domain (RBD) of SARS-CoV-2 after the first and second dose of vaccine. The patients were followed up for 6 months after vaccination.ResultsOut of 921 transplant patients, 115 (12.5%) and 239 (26%) had acceptable anti S-RBD immunoglobulin G (IgG) levels after the first and second dose, respectively. Eighty patients (8.68%) got infected with COVID-19 which led to 45 (4.9%) of patients being hospitalized. None of the patients died during follow-up period. Twenty-four (10.9%) liver transplant recipients developed liver enzyme elevation, and increased serum creatinine was observed in 86 (13.5%) kidney transplant patients. Two patients experienced biopsy-proven rejection without any graft loss.ConclusionOur study revealed that humoral response rate of solid organ transplant recipients to Sinopharm vaccine was low.

Antibiotic stewardship implementation at the largest solid organ transplantation center in Asia: a retrospective cohort study.

BACKGROUND: Using Antimicrobial stewardship programs (ASP) to monitor the use of antibiotics can lead to improved antibiotic use and reduced costs. METHODS: This retrospective cohort study was done at Shiraz Organ Transplant Center, the largest transplant center in Asia. Antimicrobial use, cost, clinical outcomes, and antibiotic resistance pattern were evaluated before and after ASP. RESULTS: This study included 2791 patients, 1154 of whom were related to the time before ASP and 1637 to the time after ASP. During the period of the research, a total of 4051 interventions were done. The use of all classes of antibiotics was significantly reduced by ASP, with 329 DDD/100PD before the intervention compared to 201 DDD/100PD after it (p = 0.04). In addition, the overall cost of antibiotics purchased was much lower after the ASP measures were implemented ($43.10 per PD) than before implementation of the ASP measures ($60.60 per PD) (p = 0.03). After the implementation of ASP, the number of MDR isolates was significantly reduced. CONCLUSION: The results of our study showed that the implementation of ASP significantly reduced the number and costs of antibiotics and also the number of resistant pathogens, but did not affect the patients' length of stay.

Assessment of Risk Factors and Clinical Outcomes in Hospitalized COVID-19 Patients with Candida spp. Co-infections: Species Distribution and Antifungal Susceptibility Patterns of Isolates.

INTRODUCTION: Fungal co-infections are considered an important complication in hospitalized patients with SARS-CoV-2 that can be attributed to disease aggravation, increased mortality, and poor outcomes. This study was conducted to determine the species distribution and antifungal susceptibility patterns of Candida isolates from hospitalized COVID-19 patients in Shiraz, Iran, in addition to associated risk factors and outcomes of co-infections with Candida species. MATERIALS AND METHODS: In this single-center study, a total of 106 hospitalized COVID-19 patients were evaluated for clinical characteristics and outcomes. Species identification was performed by ITS1-5.8S-ITS2 gene sequencing. Antifungal susceptibility testing to fluconazole, itraconazole, voriconazole, posaconazole, caspofungin, amphotericin B, and nystatin was determined according to the M27-A3/S4 CLSI protocol. RESULTS: Candida species were recovered from 48% (51/106) of hospitalized COVID-19 patients. Statistical analysis showed that patients who had heart failure, bacterial co-infection, and were receiving empirical antifungal therapy had a higher risk of developing Candida co-infection. In total, 71 Candida isolates were recovered, of which C. albicans (69%) was the most prevalent isolate. The majority of the Candida isolates were susceptible to all classes of tested antifungal drugs. DISCUSSION: Our results elucidate a high rate of Candida co-infections among hospitalized COVID-19 patients. Comorbidities such as heart failure, HTN, COPD, bacterial infections as well as therapeutic interventions including catheterization, mechanical ventilation, and ICU admission increased the risk of Candida spp. isolation from the bloodstream, respiratory tract and urine samples, which led to a higher in-hospital mortality rate. Additionally, obtained data clarified that empirical antifungal therapy was not as successful as anticipated.

Bacterial and fungal co-infections with SARS-CoV-2 in solid organ recipients: a retrospective study.

BACKGROUND: SARS-CoV-2, a novel corona virus, has caused clusters of fatal pneumonia worldwide. Immune compromised patients are among the high risk groups with poor prognosis of the disease. The presence of bacterial or fungal co-infections with SARS-CoV-2 is associated with increased mortality. METHODS: The electronic data of the liver and kidney recipients, hospitalized in COVID-19 intensive care unit in an 8-month period in 2020 were retrospectively assessed. The documented bacterial or fungal infections alongside with outcome and risk factors were recorded and analyzed by binary logistic regression model and multivariate analyses. RESULTS: Sixty-Six liver and kidney recipients with positive RT-PCR for SARS-CoV-2 were included this study. Twenty one percent of the patients had at least one episode of co-infection during their COVID-19 course. Bacterial and fungal co-infections contributed to a significantly higher mortality. Urine and sputum were the most common sites of pathogen isolation (45.45% and 36.36%; respectively). The majority of infections were caused by vancomycin- resistant Enterococci (30%). Escherichia coli stood in the next position with 23.3%. Prior hospitalization and high doses of corticosteroids were associated with co-infections (p < 0.001 and p = 0.02; respectively.) CONCLUSIONS: Bacterial and fungal co-infections with COVID-19 are more prevalent in solid organ recipients compared to the general population. Prior hospitalizations and use of broad-spectrum antimicrobial agents lead to emergence of multi-drug resistant pathogens in this susceptible patient population. Early detection and treatment of co-infections as well as antibiotic stewardship is recommended in solid organ recipients.

Evaluation of the therapeutic regimen in COVID-19 in transplant patients: where do immunomodulatory and antivirals stand?

BACKGROUND: The management of COVID-19 in organ transplant recipients is among the most imperative, yet less discussed, issues based on their immunocompromised status along with their vast post-transplant medication regimens. No conclusive study has been published to evaluate proper anti-viral and immunomodulator medications effect in treating COVID-19 patients to this date. METHOD: This retrospective study was conducted in Shiraz Transplant Hospital, Iran from March 2020 to May 2021 and included COVID-19 diagnosed patients based on SARS-CoV-2 RT-PCR positive test who had been hospitalized for at least 48 h before enrolling in the study. Clinical and demographic information of patients, along with their treatment course and the medication used were evaluated and analyzed using multiple regression analysis. RESULTS: A total of 245 patients with a mean age of 49.59 years were included with a mortality rate of 8.16%. The administration of Remdesivir as an anti-viral drug (P value < 0.001) and Tocilizumab as an immunomodulator drug (P value < 0.001) could reduce the hospitalization period in the hospital and the intensive care unit, as well as the mortality rates significantly. Meanwhile, the patients treated with Lopinavir/Ritonavir experienced a lower chance of survival (OR < 1, P value = 0.04). No significant difference was observed between various therapeutic regimens in clinical complications such as bacterial coinfections, cardiovascular and gastrointestinal adverse reactions, and liver or kidney dysfunctions. CONCLUSION: The administration of Remdesivir as an anti-viral and Tocilizumab as an immunomodulatory drug in solid-organ transplant recipients could be promising treatments of choice to manage COVID-19.

Serial transverse enteroplasty and nipple valve construction, two life saving techniques for patients with short bowel syndrome, a report of 5 cases.

BACKGROUND: Various abdominal pathologies end up with surgical resection of small intestine. When the small intestine remnant is too short for adequate fluid and micronutrients absorption, short bowel syndrome is diagnosed. The disabling condition needs a multidisciplinary approach to design parenteral nutrition, care for thrombotic, hepatic and infectious complications and gradually wean the patient from parenteral nutrition. Various surgical techniques have been introduced to increase absorptive mucosa and enhance the intestinal adaptation process. Serial transverse enteroplasty and nipple valve reconstruction are among the procedures, which will be discussed in the current article. CASE PRESENTATION: Herein, we presented 5 cases of short bowel syndrome as a consequence of abdominal laparotomies, patients were referred to our center to receive parenteral nutrition and to be prepared for the final autologous gastrointestinal reconstruction or intestinal transplantation, if indicated. CONCLUSION: Patient's age, performance status and bowel remnant length determines the appropriate technique for autologous gastrointestinal reconstruction. Serial transverse enteroplasty is designed to increase bowel's length by creating zigzag patterns through dilated bowel loops. Presence of ileocecal valve is crucial to delay intestinal transit time and to prevent colonic bacterial transfer to ileum. Patient's with ileocecal valve loss benefit from creating an artificial valve, namely, nipple valve.

Pediatric liver and kidney transplantation in the era of COVID-19: a follow-up study from a tertiary referral center in Iran.

BACKGROUND: We aimed to evaluate the impact of COVID-19 pandemic on pediatric transplant outcomes and determine whether to continue pediatric transplant activity or not, and how policies intended our center has been effective in preventing COVID-19 among organ transplant recipients. METHODS: We conducted a single-center, retrospective, cohort study of hospitalized pediatrics after organ transplantation at Shiraz transplant center since March to August 2020. All liver and kidney transplanted children were included the study and their laboratory and clinical related COVID-19 characteristics were followed up till 3 months after transplantation during hospitalization period and then weekly by the transplant committee. RESULTS: Fifty-one patients underwent transplantation including 11 kidney and 40 liver recipients. The mean age of the pediatric cases was 6.72 ± 5.47 years. A total of 11 patients died due to post-transplant complications, while none of the patients presented any sign or symptoms in favor of COVID-19 in the hospital course after transplantation. Six transplants including 2 kidney and 4 liver were canceled when positive PCR tests were detected in their donors before the surgery. In the 3 months of follow up, two patients presented with symptoms including high grade fever, malaise, rhinorrhea, and GI symptoms. Both patients had two negative PCR, and no radiologic or laboratory results regarding COVID-19 were also detected. One had positive influenza PCR, while the second one had a positive serologic test for EBV; CT, computed tomography CONCLUSION: Transplant programs could continue their activities during the COVID-19 pandemic with specific case selection, accurate screening methods and following protective protocols.

Lessons learned from successful autologous gastrointestinal reconstruction in patients with intestinal failure: a case series.

BACKGROUND: Intestinal failure (IF) is a rare but severe form of organ failure. The condition is defined as body's inability to absorb adequate fluids, macronutrients and minerals for growth and development, so that intravenous supplementation is necessary. A broad spectrum of diseases, trauma and complications of surgery might eventually end up with intestinal failure. Nowadays, intestinal failure patients are preferably cared for in intestinal rehabilitation units (IRU). Autologous gastrointestinal reconstruction (AGIR) refers to non-transplant operative management of IF patients designed to improve enteral tolerance and gut absorptive capacity. CASE PRESENTATION: Herein we present five cases with complications of surgeries due to peptic ulcer bleeding, blunt abdominal trauma, obesity and gastric tumor. The surgeries were complicated by anastomotic leak, peritonitis and fistula formation. By adopting multidisciplinary decisions and special care for each complication, all the five patients were successfully managed and discharged. DISCUSSION AND CONCLUSIONS: As presented, re-anastomosis in presence of abdominal contamination will probably fail. In patients with intestinal failure, PN should start as soon as possible to increase the success rate of future surgeries and prevent potential need for intestinal transplantation. We suggest referring patients with complicated outcomes of gastrointestinal surgeries to the IRUs to reduce morbidity and mortality.

Protective effects of silymarin on preventing vancomycin nephrotoxicity in infectious patients: a randomized, double-blinded, placebo-controlled, pilot clinical trial.

Nephrotoxicity is one of the most common complications of vancomycin use in clinical practice. Silymarin has potential to be a renoprotective agent for nephrotoxic drugs due to its antioxidant, anti-inflammatory, and anti-apoptotic effects. The aim of this clinical study is evaluating the potential effects of silymarin on preventing vancomycin nephrotoxicity. A multicenter, randomized, double-blinded, placebo-controlled, clinical trial was conducted on patients with the indication of systemic vancomycin for at least 7 days. Patients were screened daily and those who met the inclusion criteria were selected and randomly assigned into either silymarin or placebo groups. Accordingly, 140 mg silymarin tablet (Livergol®) or placebo was given orally three times daily. Silymarin or placebo were provided in conjunction with vancomycin for at least 7 days. If vancomycin therapy was extended beyond 7 days, the administration of silymarin or placebo was continued until the end of vancomycin treatment. Malondialdehyde, glutathione, and total antioxidant capacity were measured in the serum on days 0 and 7. A trough level of vancomycin was assessed 30 min before the fifth dose of vancomycin. Acute kidney injury (AKI) was monitored in each patient daily during the course of vancomycin treatment. The causality assessment of all identified cases of vancomycin associated AKI was performed by the Naranjo scale. The primary endpoint was vancomycin nephrotoxicity. It was defined based on the KDIGO 2012 criteria for AKI as either an increase of 0.3 units or more in serum creatinine level during 48 h or 50% (1.5-fold) or more during 7 days compared to baseline values. During the study period, 34 patients in the silymarin group and 32 patients in the placebo group completed the clinical trial. Demographic, baseline clinical, and laboratory characteristics were comparable between placebo and silymarin groups. The number of patients with AKI on days 5, 6, 7, 11,12, 13, and 14 in the placebo group was significantly higher than that in the silymarin group (p-value < 0.05). The incidence of acute tubular injury on the day  5 and 7 of vancomycin treatment was significantly lower in the silymarin group (p-value = 0.005 and p-value = 0.032, respectively). Antioxidant indexes including serum total antioxidant capacity and glutathione significantly increased in the silymarin group (p-value < 0.001 for both indexes). In contrast, serum malondialdehyde as an end product of lipid peroxidation pathway significantly decreased in the silymarin group during 7 days (p-value < 0.001). The results of the present pilot, clinical trial suggested that silymarin co-administration may prevent vancomycin nephrotoxicity.

Disseminated Gastrointestinal Basidiobolomycosis: A Case Report with Review of Diagnostic Clues.

Introduction: Basidiobolomycosis is a rare fungal infection caused by an environmental saprophyte, Basidiobolus ranarum. It usually presents as a chronic subcutaneous infection; however, few cases of gastrointestinal involvement have been reported. The exact transmission route of gastrointestinal cases is not clear, and diagnosis always requires a high index of suspicion because it tends to mimic other inflammatory and neoplastic conditions. Case Report. A 31-year-old immunocompetent woman presented with abdominal pain and an advanced colon mass. She was completely well until about 1.5 years ago, when she underwent bariatric surgery. One year after surgery, chronic abdominal pain developed. A colonoscopy showed an ulcerative lesion in the descending colon, and the biopsy was in favor of ulcerative colitis. Despite immunosuppressive treatment, there was no improvement, and with worsening symptoms, more investigations revealed advanced colon mass with entrapment of the stomach and pancreas. Colonic mucosa biopsy and trucut biopsy of the mass showed just necrosis and acute inflammation; thus, she underwent exploratory laparotomy with colectomy, partial gastrectomy, distal pancreatectomy, and left nephrectomy. On pathologic examination, there was granulomatous inflammation plus the Splendore-Hoeppli phenomenon around fungal hyphae, which was diagnostic for gastrointestinal basidiobolomycosis. Previous pathology slides were reviewed and revealed a tiny focus of basidiobolomycosis. After 6 months of treatment with itraconazole, she is relatively well without any clinical or radiologic abnormalities. Conclusion: Our case highlights the significance of suspicion for basidiobolomycosis in ulcerative and necrotic lesions with increased eosinophils, especially in the presence of abdominal mass and systemic eosinophilia.

Quality of life associated with immunosuppressant treatment adherence in liver transplant recipients: A cross-sectional study.

Purpose: Transplanted organ survival after solid organ transplantation highly correlates with the adherence levels of the patients to their immunosuppressive drugs. On the other hand, one of the main goals of liver transplantation is to increase the overall quality of life (QOL) for the patient. This study is aimed to analyze the relationship between adherence and QOL in adult liver transplant recipients of the biggest liver transplant center in Asia. Methods: All of the included patients were older than 18 years and at least 6 months had passed from their liver transplantation. The adherence level was measured with BAASIS method and the QOL was assessed by SF-36 questionnaire in real-time interviews. The relationship between adherence and different aspects of QOL in addition to qualitative and quantitative influential factors on these two outcomes was calculated with statistical analysis. Results: Among the 122 included patients, 41% of the were categorized in the non-adherent group. The most important reasons for non-adherence in these patients included forgetfulness (62%), lack of medication (12%), financial problems for drug supply (9%), and side effects (2%). According to the results of the multivariate linear regression model, rejection was the only influential factor in the occurrence of non-adherence among patients (OR = 8.226 CI (1.404-48.196)). The overall mean QOL score of patients was reported 51.09 ± 21.86. The lowest is given to social functioning, while mental health has achieved the highest score. The mean QOL scores in different dimensions in patients with adherence were higher than non-adherents, which was only significant in mental health (p-value = 0.01). Additionally, in total scores related to Physical Composite Score (PSC) and Mental Composite Score (MCS), the mean MSC scores in adherent patients were significantly higher than non-adherent patients (p-value: 0.02). Although adherent patients have an overall greater QOL, the only meaningful effect on QOL total score was from income level. Conclusion: The overall QoL score has been in all parameters higher in the adherent group compared with non-adherent patients. The difference in QoL was most meaningfully significant in mental composite score among other parameters of QoL.

Novel technique for arterial reconstruction in simultaneous pancreas-kidney transplantation, a randomized clinical trial.

INTRODUCTION: Simultaneous pancreas kidney (SPK) transplantation is an invaluable procedure to enhance the quality of life of insulin-dependent patients with advanced renal disease. The creation of vascular anastomoses of the donor's pancreas vessels to the recipient's, is of utmost importance to predict the graft outcome and surgical complications. In the study we introduce a novel technique for arterial reconstruction during SPK transplantation. METHODS: Conventionally, during the SPK transplantation, a so-called Y-graft is anastomosed between donor's superior mesenteric and splenic artery to the recipient's right iliac artery. In the study we adopted a new technique by preparing an extra extension using the donor's carotid artery, to be anastomosed to the Y-graft and the iliac artery. In this non-blinded randomized clinical trial we compared the surgical complications and early outcomes between the 2 groups of patients with the traditional and new arterial reconstruction techniques during 3 months after transplantation. RESULTS: Thirty adult patients were included in the study. The incidence of pancreatitis, vascular thrombosis and surgical site infection was lower in the new Y-graft and extension technique, which was not statistically significant. However, the calculated Cohen's d index showed the medium effect of new Y-graft and extension technique on complication after SPK transplantations. CONCLUSION: The post-operative complications tend to be lower in the novel arterial reconstruction technique, however a study on a larger patient group is encouraged to confirm our primary results. TRIAL REGISTRATION: The study was registered at the Iranian Registry of Clinical Trials on 12/05/2022; IRCT 20210625051701N2; ( http://www.irct.ir/ ).

Pharmacokinetic and Pharmacodynamic Considerations of Novel Antibiotic Agents for Pediatric Infections: A Narrative Review.

Background: Currently, the escalation of microbial resistance poses a significant global challenge. Children are more susceptible to develop infections and therefore are prescribed antibiotics more frequently. The overuse and misuse of antibiotics in pediatric patients can play a considerable role in developing microbial resistance. Accordingly, many policies, including research into new antibiotic agents have been recommended to combat microbial resistance. Recent developments in novel antibiotics have shown promising results against multi-drug resistant (MDR) and extensive drug resistance (XDR) pathogens. However, as pediatric patients are typically excluded from the clinical trials of new medications, labeling and information about approved antibiotics should be improved. This study aimed to evaluate antibiotics having been introduced to the market in the last decade focusing on pediatric population. Methods: This study reviewed the published literatures on novel FDA-approved antibiotics released between 2010 and 2022. Results: Finally, seven newly approved antibiotics including ceftaroline fosamil, ceftazidime-avibactam, ceftolozane-tazobactam, ceftobiprole, imipenem-cilastatin-relebactam, meropenem-vaborbactam, and tedizolid were considered in the present review-article. All relevant data extracted from literatures, were discussed in different subtitles of "Pharmacology", "Mechanism of action", "Indication", "Dosage regimen and pharmacokinetic and pharmacodynamic properties", "Dosage adjustment in renal/liver failure", "Resistance pattern", and "Adverse drug events". Conclusion: This study reviewed available data on seven new antibiotic agents and their pharmacodynamic and pharmacokinetic properties, with a particular focus on their use in pediatric patients. The information presented in this review will be useful for healthcare professionals in selecting appropriate antibiotics for pediatric patients and for researchers in achieving the ideal therapeutic regimens.

Vitamin D status as a predictor for liver transplant outcomes.

It is well known that vitamin D plays a pivotal role in immune system modulation; however, its role in liver transplantation (LT) has not yet been well elucidated. This study aimed to assess the association between vitamin D status and LT outcomes. This retrospective cohort study was conducted on 335 registered cirrhotic patients with end-stage liver disease (ESLD) who underwent LT during 2019-2021 and had measurement of serum vitamin D before LT. The association of vitamin D levels before LT with the odds of acute cellular rejection (ACR) and risk mortality was assessed by applying logistic and cox regression, respectively. The mean MELD-Na and serum level of vitamin D were 20.39 ± 9.36 and 21.52 ± 15.28 ng/ml, respectively. In the final adjusted model, there was a significant association between vitamin D deficiency in the pre-transplant period and odds of ACR (odds ratio [OR] 2.69; 95% confidence interval [CI] 1.50-4.68). Although in the crude model, vitamin D deficiency in the pre-transplant period was significantly associated with an increased risk of mortality after two years of follow-up (Hazard ratio (HR) = 2.64, 95% CI 1.42-4.33), after adjustment for potential confounders, the association of vitamin D status and mortality became non-significant (HR = 1.46, 95% CI 0.71-3.00). The present study provides evidence that pre-transplant serum vitamin D levels may be a predictor for ACR in patients with cirrhosis undergoing LT.

Drug-related Problems in Solid-Organ Transplant Recipients Hospitalized for COVID-19: An Experience of a Referral Tertiary Center in Iran.

Background: Transplanted patients receiving immunosuppressive agents are at a higher risk of Coronavirus-disease-2019 (COVID-19), and their polypharmacy state makes the choice of treatment challenging. This study aimed to assess the drug-related problems (DRP) and clinical pharmacists' interventions to manage transplanted patients and candidates for transplantation with COVID-19. Methods: This cross-sectional study was conducted in the COVID-19 intensive care unit of Shiraz Organ Transplantation Center (Iran), from March 2020 to April 2021. Patients were admitted to the COVID-19 intensive care unit based on clinical symptoms or positive polymerase chain reaction (PCR) tests. The clinical pharmacist reviewed all medications and physicians' orders on a daily basis and evaluated DRPs in accordance with the pharmaceutical care network of Europe (PCNE) classification (V 8.01). The treatment team was informed of the DRPs, and the acceptance or rejection of the intervention was also documented. Data were analyzed using SPSS (Version 25.0). In order to determine the proportion and determinants of drug-related problems, descriptive statistics and logistic regression were applied, respectively. Results: A clinical pharmacist reviewed 631 individuals with 11770 medication orders, and 639 DRPs were found in 69% of them with an average of 1.01±1 per patient. The most commonly reported DRPs were treatment efficacy issues followed by adverse drug reactions (ADRs). A total of 982 interventions were provided at prescriber, patient, and drug levels, of which 801 were accepted, and 659 (82.27%) were fully implemented. Conclusion: There have been considerable drug-related issues in managing transplanted patients with COVID-19. DRPs are more common in people with polypharmacy, more than three comorbidities, and hydroxychloroquine regimens.

The experience and outcomes of multidisciplinary clinical pharmacist-led parenteral nutrition service for individuals with intestinal failure in a center without home parenteral nutrition.

BACKGROUND/OBJECTIVES: Intestinal Failure (IF) is a rare but serious form of organ failure, and patients with IF are dependent on Total Parenteral Nutrition (TPN) to maintain growth and development. This study aimed to describe the experiences of a multidisciplinary clinical pharmacist-led TPN service in the Intestinal Rehabilitation Unit of Shiraz Organ Transplant Center. SUBJECTS/METHODS: This prospective study was conducted in Shiraz Organ Transplant Center, Iran from February 2018 to October 2020, including seven months with and 24 months without the clinical pharmacist involvement. Clinical and nutritional outcomes as well as the potential complications of TPN were compared in these two periods. RESULTS: This study was conducted on 107 patients. The most important complication occurred among the patients receiving TPN were catheter infection (42.05%), sepsis, and catheter thrombosis (18.69%). Portal vein thrombosis (OR = 26.56) and length of Intensive Care Unit (ICU) stay (OR = 1.12) were significantly associated with the rate of parenteral nutrition-associated liver disease. The results also revealed an association between the rate of sepsis and history of malignancy, catheter thrombosis, length of the small bowel, length of PN, length of hospital stay, and length of ICU stay. Moreover, the results showed a significant difference regarding the patients' outcomes and TPN complications before and after the clinical pharmacist interventions (P < 0.05). CONCLUSION: Working as a multidisciplinary team in Intestinal Rehabilitation Unit (IRU) has been suggested to improve patients' outcomes and reduce mortality and morbidity. Presence of a clinical pharmacist in this team can help improve the TPN service provided for individuals with IF.

Epidemiology, clinical features, therapeutic interventions and outcomes of mucormycosis in Shiraz: an 8-year retrospective case study with comparison between children and adults.

Mucormycosis is an invasive fungal infection with high morbidity and mortality rate despite the early diagnosis and proper therapeutic interventions. Given the importance of epidemiological data in reviewing the attitude toward infectious diseases in developing countries, the current retrospective case study aimed to compare the epidemiological aspects, risk factors, clinical characteristics, therapeutic interventions, and outcomes of mucormycosis between adults and children during eight years (2013-2021) in the main infectious disease referral centers in the southwest of Iran. The median age of 164 patients included in this study was 47 years (IQR 22-59). The median length of hospitalization was 33 days.The annual incidence of mucormycosis-related hospitalizations was estimated 1.76 per 10,000 admissions during the study period. Moreover, the incidence of infection was 2.4 times higher in males than females in children. Diabetes mellitus was the most frequent predisposing factor in adults (46.0%). The main risk factor in children was hematologic malignancy (52.6%), but a considerable proportion of them (28.9%) were immunocompetent.The most frequent antifungal agent used was liposomal amphotericin B (82.3%) as monotherapy. The combination therapy was used more in adults (15.8%) than children (7.9%). In addition, surgical intervention with antifungal therapy was considered the most effective therapeutic approach. The in-hospital mortality rate was 14.6% for adults, whereas it was zero for children. Our findings provide a recent epidemiologic analysis of mucormycosis among hospitalized patients in both children and adults. Mucormycosis mainly affects individuals with diabetes mellitus or hematological malignancies and presents as rhino-orbito-cerebral form. Proven diagnosis of mucormycosis according to clinical manifestations and histopathology observations accompanied by proper antifungal treatments may improve survival rates.

The effect of taurine supplementation on delirium post liver transplantation: A randomized controlled trial.

BACKGROUND & AIMS: Delirium is a prevalent complication of liver transplantation (LT). It may enhance the risk of morbidity and mortality. Taurine is considered to have antioxidant and neuroprotective activities. The aim of this study was to evaluate taurine supplementation effect on post-LT delirium. METHODS: Patients older than 18 years old who had received LT in Abu-Ali Sina transplantation center in Shiraz, Iran from September 2020 to June 2021, were enrolled in this double-blinded randomized clinical trial. Exclusion criteria was known hypersensitivity to taurine, pregnancy or breast-feeding and death within 72 h post-LT. Patients were randomly divided into two groups, each received 2 g/day placebo or taurine from the first day post-LT for 30 days. Delirium was assessed using Confusion Assessment Method-Intensive Care Unit (CAM-ICU). Mortality and rejection rates and length of Intensive Transplantation Unit (ITU) and hospital stays were evaluated within one month after transplantation. RESULTS: Two hundred and seven patients were divided into two groups. Twenty-eight and 23 patients were excluded due to their refuse to participate in the study and death within 72 h post-LT, respectively. Delirium rate within the first month was 23.08% and was significantly lower in taurine group (9.46%) compared with placebo (35.36%, P = 0.012). Length of ITU stay was significantly higher among delirious patients (P = 0.015) in this analysis. CONCLUSION: we reached to the result that taurine can prevent post-LT delirium, dramatically. Placebo receiving and longer stay in ITU were the only independent risk factors in this trial. REGISTRATION NUMBER OF CLINICAL TRIAL: The study was registered at the Iranian Registry of Clinical Trials (IRCT20200312046755N1; http://www.irct.ir/).

Passenger Lymphocyte Syndrome as a rare cause of hemolysis in a patient after small intestine transplantation, A case report and review of the literature.

Passenger lymphocyte syndrome (PLS) is a well-described phenomenon causing immune hemolytic anemia, mostly in non-ABO identical transplantations. The syndrome occurs when donor lymphocytes produce antibodies against the recipient's red blood cells. Although the syndrome is usually self-limited, further management with blood transfusions, immunosuppression, or plasmapheresis might be needed. A 23-year-old female with AB+ blood group underwent small intestine transplantation from a deceased donor with O+ blood group.

Previous cases have been successfully treated with a combination of immune suppression, plasma exchange, and transfusions.
