Association between cumulative rATG induction doses and kidney graft outcomes and adverse effects in kidney transplant patients: a systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis were performed to explore the association between rabbit thymoglobulin (rATG) doses and transplant-related efficacy and safety outcomes. METHODS: We searched PubMed and Scopus databases from inception up to June 2020. The primary efficacy and safety endpoints in kidney transplant recipients were evaluated. RESULTS: Data of 23 cohort studies (3457 patients) and three RCTs (154 patients) were extracted and analyzed. rATG doses of ≤4.5 m/kg was associated with lower rates of biopsy proven acute rejection, cytomegalovirus infection, BK virus infection, and malignancy with a comparable rate of delayed graft function, patients' mortality, and death-censored graft loss compared to rATG total doses of 4.5-6 mg/kg or more than 6 mg/kg. The rATG doses of 3-4.5 mg/kg was associated with better outcomes in dose-response analysis. EXPERT OPINION: Cumulative rATG induction doses as much as 3-4.5 mg/kg is as effective as higher doses regarding to allograft and patient outcomes while minimizing potential adverse effects in kidney transplant recipients.

Dose discordance of direct acting oral anticoagulants using different equations for estimating GFR: a literature review.

INTRODUCTION: Direct oral anticoagulants (DOACs) are widely prescribed nowadays. Available DOACs are renally eliminated to some extent and need dose adjustment in patients with kidney dysfunction. Cockcroft-Gault (CG) formula has been used to estimate creatinine clearance in DOACs trials. Nowadays, Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) are preferred equations for estimating glomerular filtration rate (GFR). We reviewed studies that simulated DOACs dosing in patients with atrial fibrillation by MDRD, CKD-EPI, and CG. AREAS COVERED: DOACs dose discordance varies from 28.8% underdosing to 59.2% overdosing when MDRD or CKD-EPI equations are substituted for CG. MDRD and CKD-EPI overestimate the GFR in lower thresholds of kidney function especially in elderly and females and result in overestimation of DOACs dosing or misclassifying the patients to be eligible for receiving DOACs when they are contraindicated. Compared with CG, MDRD and CKD-EPI underestimate the level of kidney function in higher GFR extremes and in these patients suggest DOACs when they are not recommended or suggest lower doses. EXPERT OPINION: Until running large clinical studies on efficacy/safety of DOACs dosing using MDRD or CKD-EPI equations, use of CG method for DOACs dosing is recommended in real practice.

Treatment of vincristine-induced ileus with metoclopramide: A case report.

INTRODUCTION: Acute lymphoblastic leukemia is an invasive malignancy which ought to be treated with several cytotoxic medications. Vincristine-based regimen is among the most commonly used regimens for the treatment of adult acute lymphoblastic leukemia. Peripheral neuropathy caused by vincristine provides a limitation in dose administration and can influence the treatment outcome and patient's quality of life. CASE PRESENTATION: Ileus and constipation occurred as a result of autonomic neuropathy in a 58-year-old man who underwent vincristine-based regimen for acute lymphoblastic leukemia treatment. Despite the administration of several laxative agents for constipation, the complication did not improve. So metoclopramide as a prokinetic agent was administered intravenously, and patient bowel movement and defecation started after 24 h. CONCLUSIONS: There is no approved protocol for vincristine-induced autonomic neuropathy treatment; thus, prokinetic agents such as metoclopramide can be considered as an option for ileus treatment after ruling out the possibility of bowel obstruction. Prophylactic stool softeners should be administrated in all patients undergoing chemotherapy with vincristine to prevent gastrointestinal motility disorders.

Effects of pre-transplant L-carnitine supplementation on primary graft dysfunction in liver transplant recipients: a pilot, randomized, placebo-controlled clinical trial.

Primary graft dysfunction (PGD) and non-function (PNF) happen in 8.7-24.7% and 0.9-7.2% of liver transplant recipients, respectively. These phenomena increase treatment cost and patients' death. This study assessed the effect of L-carnitine supplementation on the incidences of PNF/PGD in liver transplant recipients. This randomized, placebo-controlled, clinical trial was performed on adult liver transplant recipients. Patients took L-carnitine syrup 500 mg three times daily or placebo from the time of including in transplant waiting list until the day of transplant surgery (median 14 days, 1-192 days). Thirty-three patients in L-carnitine and 39 patients in placebo group completed the study. Although not statistically significant, PNF and PGD happened less frequently among recipients in L-carnitine compared with placebo group (3% vs. 12.8% for PNF; 15.2% vs. 30.8% for PGD). Alanine aminotransferase (ALT) and aspartate aminotransferase were lower in L-carnitine group at day 3 after transplantation. ALT declined more significantly within 48 h after transplantation in L-carnitine arm (median 120.50 vs. 79 IU/L; P = 0.03). One-month patients' survival was significantly higher in L-carnitine versus placebo group (97% vs. 74.4%; P = 0.008). The rates of PNF and PGD in L-carnitine group were approximately one-fourth and one-half of placebo group respectively. One-month patients' survival was higher in L-carnitine group.

Comparison of the Efficacy of Combination Therapy of Prednisolone - Acyclovir with Prednisolone Alone in Bell's Palsy.

OBJECTIVE: Bell's palsy is a rapid onset, usually, unilateral paralysis of the facial nerve that causes significant changes in an individual's life such as a decline in personal, social, and educational performance. This study compared efficacy of combined prednisolone and acyclovir therapy with prednisolone alone. MATERIALS & METHODS: This study is a randomized controlled trial conducted on 43 Children (2-18 years old) with Bell's palsy. The first group of 23 patients was treated with prednisolone and the remaining patients were treated with a combination of prednisolone and acyclovir. The required data were extracted, using an informational form based on the House-Brackmann Scale, which grades facial nerve paralysis. The data were analyzed with Mann-Whitney test using SPSS version 16. RESULTS: The mean age of the first and second group were 8.65 ± 5.07 and 8.35 ± 4.92 years, respectively, (p=0.84). Sixty one percent and 39% of patients in the first group, and 45% and 55% of patients in the second group were male and female, respectively. No significant differences exist between the groups in terms of age and gender. The rate of complete recovery was 65.2% in group I and 90% in the group II (p=0.04). CONCLUSION: The results of this study showed that the combined prednisolone and acyclovir therapy of patients with Bell's palsy is far more effective than treatment with prednisolone alone. Actually, age and gender had no impact on the rate of recovery.

Comparison between the Ability of Glasgow Coma Scale and Full Outline of Unresponsiveness Score to Predict the Mortality and Discharge Rate of Pediatric Intensive Care Unit Patients.

OBJECTIVE: Prediction of survival and mortality rates in costly environments such as the intensive care unit (ICU) is of great importance for the assessment of new treatments, resource consumption control, and improvement of quality control. This study aimed to determine the ability to predict mortality and discharge rate of patients using the FOUR score in the pediatric ICU (PICU) of Ali Ibn Abitalib Hospital, Zahedan and compare the results with those of Glasgow Coma Scale (GCS). METHODS: This prospective study was conducted on 200 patients admitted to the PICU. Convenience purposive sampling was used. Research data was collected using the Full Outline of Unresponsiveness (FOUR) score and GCS using questionnaires. Obtained data was analyzed with SPSS 16 using descriptive statistics and correlation analyses. FINDINGS: Of the 200 children admitted to the PICU, 71.5% and 28.5% were discharged and died, respectively. The inter-rater reliability for the FOUR score was good to excellent (weighted κ: eye, 0.72; respiration, 0.82; brainstem, 0.74; motor, 0.78), In terms of mortality and discharge prediction, logistic regression analyses (FOUR score = OR: 0.13; 95% CI: 0.06-0.29; P<0.001; GCS=OR: 2.49; 95% CI: 1.44-4.32; P<0.001) showed that the FOUR score is a good predictor for in-hospital mortality. CONCLUSION: Results indicated that the FOUR score is more capable than GCS in predicting the mortality and discharge of patients admitted to the PICU.
