Introduction: Impaired cardiac function is one of the most concomitant symptoms in patients with kidney failure after long-term dialysis. In addition, the preservation of adequate perfusion pressure to the graft plays a significant role in the intraoperative management during kidney transplantation, but the use of positive inotropic drugs in kidney transplant patients has been studied less. We investigated the protective effects of renal function by means of cardiac inotropes in kidney transplant patients. Methods: Eighty-nine patients that received kidney transplantation between April 2014 and December 2016 at Qilu Hospital were included and randomly divided into the treatment group receiving levosimendan and a control group. All kidney recipients received ABO-compatible donors. A poor outcome was defined as one of the following: delayed graft function, graft hemorrhage, or nephrectomy. Results: The treatment group had a better composite outcome and the level of neutrophil gelatinase-associated lipocalin was also lower than in the control group. Conclusion: Inotropic drugs may play a protective role in renal function in kidney transplantation.

Abstract Background This study aimed to investigate the phylogenetic characterization and virulence traits of uropathogenic Escherichia coli (UPEC) isolated from kidney transplant patients (KTPs) as well as non-KTPs and analyze the clonal distribution of Extended spectrum β-lactamases (ESBLs)-producing UPEC containing blaCTX-M gene. Methods To this end, we determined virulence marker and the phylogenetic characterization of UPEC in non-KTPs (n = 65) and KTPs (n = 46). The non-KTPs were considered the control group of the study. Also, according to the Achtman scheme, we performed multilocus sequence typing to assess the relationship between twenty-nine of ESBL-producing isolates containing blaCTX-M gene. Results According to the results of PCR assay, the prevalence of virulence factor genes ranged from 0% (cnf and papG III) to 93.7% (fimH). Also, KTP isolates significantly differed from non-KTP isolates only in terms of the prevalence of pap GI elements. Moreover, the most frequent UPEC isolates were in phylogenetic group B2, followed by group D (18.9%), and group A (13.5%). Furthermore, except for phylogenetic group C, there was no significant correlation between phylogenetic distribution in KTPs and non-KTPs. Additionally, MLST analysis of blaCTX-M carrying isolates identified 18 unique sequence types (ST) the most common of which was ST131 (24.1%), followed by ST1193 (10.3%), while fourteen STs were detected only once. Conclusions The results further revealed significant differences between the UPEC isolates from KTPs and non-KTPs regarding the phylogroups C and PAI gene. Based on MLST analysis, we also observed a relatively high diversity in UPEC isolates obtained from KTPs and non-KTPs. Moreover, clonal complex (CC) 131 and ST131 were found to be the most prevalent clones and ST types, respectively. Besides, for the first time, ST8503 were reported in KTPs. These results suggested regular studies on characterization of UPEC isolates among KTPs.

Background Attenuated immune responses to mRNA SARS-CoV-2 vaccines have been reported in solid organ transplant recipients. Most studies have assessed serological responses alone, and there is limited immunological data on vector-based vaccines in this population. This study compares the immunogenicity of BNT162b2 with ChAdOx1 in kidney transplant patients, assessing both serological and cellular responses. Methods 920 patients were screened for spike protein antibodies (anti-S) following 2 doses of either BNT162b2 (n=490) or ChAdOx1 (n=430). 106 patients underwent assessment with T-cell ELISpot assays. 65 health care workers were used as a control group. Results Anti-S was detected in 569 (61.8%) patients. Seroconversion rates in infection-naïve patients who received BNT162b2 were higher compared with ChAdOx1, at 269/410 (65.6%) and 156/358 (43.6%) respectively, p<0.0001. Anti-S concentrations were higher following BNT162b, 58(7.1-722) BAU/ml, compared with ChAdOx1, 7.1(7.1-39) BAU/ml, p<0.0001. Calcineurin inhibitor monotherapy, vaccination occurring >1st year post-transplant and receiving BNT162b2 was associated with seroconversion. Only 28/106 (26.4%) of patients had detectable T-cell responses. There was no difference in detection between infection-naïve patients who received BNT162b2, 7/40 (17.5%), versus ChAdOx1, 2/39 (5.1%), p=0.15. There was also no difference in patients with prior infection who received BNT162b2, 8/11 (72.7%), compared with ChAdOx1, 11/16 (68.8%), p=0.83. Conclusions. Enhanced humoral responses were seen with BNT162b2 compared with ChAdOx1 in kidney transplant patients. T-cell responses to both vaccines were markedly attenuated. Clinical efficacy data is still required but immunogenicity data suggests weakened responses to both vaccines in transplant patients, with ChAdOx1 less immunogenic compared with BNT162b2.

Kidney transplantation is the famous and most important choice of treatment of renal replacement therapies (RRTs) because of its positive impact on morbidity, survival and cost. The health related quality of life is becoming important outcome. Quality of life is usually impaired in patients who have renal transplant because of renal transplant patients have anxiety, lack of social, physical and emotional support and diminished ability to take care of themselves. The basic purpose of renal transplantation is to achieve maximum quality of life with minimum side effects. Methods: A cross sectional study was conducted at Rukhsana Akhtar Bahria International Orchard Hospital Lahore after approval from institution board of university of Lahore. 36 patients were enrolled in study by using purposive sampling technique. After taking informed consent all Kidney transplant patients aged between 18 years to 60 years, visited the post-transplantation OPD and continuously in follow-up sessions were included in study. A validated and standard WHO questionnaire of “Kidney Disease and Quality of Life (KDQOL-36™)” was used for data collection. Data was entered and analyzed in SPSS version.21.Chi-square test was applied to find out significant association between qualitative variables. P -Value < 0.05will be considered as statistically significant. Results: Majority of patients were from 40-49 years 10(27.0%). Females were more as compared to men (20(55.6) vs 16(44.4%)). 10(27.8) patients can read and write and 8(22.2%) have done matriculation. More patients live in Urban area as compared to rural area(19(52.8%) vs 17(47.2%)).8(22.2%) patients have less than 1 year of post kidney transplantation time and 19(52.8%) have 1 to 3 years. All the seven domains of KDQOL show poor QOL. General Health, Physical function and physical and emotional function shows average QOL and Emotional, social, daily activities and overall KDQOL shows poor QOL. There was insignificant association with age, gender, education; residential area and Post kidney transplantation length of time (years)(p-value > 0.05). Conclusions: After renal transplantation HRQOL becomes very important factor. After kidney transplantation HRQOL depends on many factors. It was concluded from current study that the HRQOL was not as good as it should be. Over the period of transplantation time patient’s quality of life remain same. The society, government, family, and medical staff need to support patients so they can also improve their QOL. Key word: Renal Diseases, Kidney transplant, Quality of life, KDQOL-36

Abstract Background and Aims Post-transplant weight gain and particularly visceral fat gain has been linked to the development of metabolic disorders and cardiovascular disease. Moreover, the effect of obesity on graft function after kidney transplantation has recently become a subject of interest. The aim of our study was to investigate the association of body mass index (BMI), body fat percentage (BF%) and waist-to-hip ratio (WHR) with the kidney function in kidney transplant patients. Method We conducted a cross-sectional study that enrolled 80 kidney transplant patients aged 23–75 years (mean age 46.7 ± 11.5 years, 60% males). Anthropometric measurements of weight, height, waist, and hip circumferences in addition to skinfold thickness were obtained. BH% was calculated using a 4-site skinfold thickness method calculated through the Jackson-Pollock equation with a Harpenden caliper, utilizing a BF% cutoff of 35% for women and 25% for men to define obesity. Results The calculated BMI in our study group was 32.7±8.7 kg/m2, a mean BF% of 29.9±8.5% and a mean WHR of 0.9±0.1 Statistically significant difference in GFR, BMI, WHR and BF% were observed between males and females (r=0.455, p=0.02; r=0.412, p=0.016; r=0.437, p=0.022; r=0.348, p=0.011), respectively. After adjustment for age, gender, donor group, donor age and years of dialysis before transplantation, higher levels of all obesity measures were related to lower eGFR: BMI per 1 SD (β coefficient −3.883, 95% confidence interval [CI] −5,422 to −3,132), WHR (β coefficient −4.443, 95% CI −6.201 to −3.772), and BF% (β coefficient −3.722, 95% CI −4.332 to −3.461). The combination of higher BF% (BF% &gt;33 kg/m2) and central obesity (WHR &gt;0.85 for women, &gt;0.90 for men) was associated with the lowest eGFR compared with that in lean subjects. Conclusion The combination of high BF% and WHR may be an important risk factor for lower GFR in a kidney transplant recipient.

Introduction: Ureteral stricture (US) in the kidney transplant recipient is a rare complication that can lead to morbidity and graft loss. Risk factor recognition is crucial in the prevention and management of this entity. Delayed graft function (DGF), as defined by the need for dialysis in the first week after transplantation, has been proposed as a risk factor in previous studies. Our objective is to determine the impact of DGF in US development in kidney transplant patients. Methods: We designed a matched case-control study. US cases in kidney transplant recipients were identified in the 2008–2017 period. We defined US as the rise in serum creatinine associated with findings suggesting obstruction in ultrasound, scintigraphy, or retrograde pyelogram; any other cause of graft dysfunction was excluded. Controls were defined as kidney transplant recipients from the same population and period without US, matched in a 1:2 fashion by age, sex, and donor type. Results: From 532 kidney transplant patients, 31 cases and 62 controls were included. Cumulative US incidence was 58 per 1000 cases. When calculating for odds ratio (OR), post-operative urinoma (OR 3.2; 95% confidence interval [CI] 2.36–4.37) and ureteral duplication (OR 3.29; 95% CI 2.40–4.51) were associated with an increased risk for US, while DGF was not found to be statistically significant as a risk factor (OR 3.3; 95% CI 0.96–11.52). No statistically significant differences were found between groups in other pre- and post-transplant-related factors. Conclusions: DGF was not associated with US in our cohort; however, ureteral duplication and postoperative urinoma were associated with an increased risk of graft ureteral stenosis development.
