Transgelin is a 22-kDa protein involved in cytoskeletal organization and expressed in smooth muscle tissue. According to animal studies, it is a potential mediator of kidney injury and fibrosis, and moreover, its role in tumorigenesis is emerging in a variety of cancers. The study included 126 ambulatory patients with multiple myeloma (MM). Serum transgelin-2 concentrations were measured by enzyme-linked immunoassay. We evaluated associations between baseline transgelin and kidney function (serum creatinine, estimated glomerular filtration rate—eGFR, urinary markers of tubular injury: cystatin-C, neutrophil gelatinase associated lipocalin—NGAL monomer, cell cycle arrest biomarkers IGFBP-7 and TIMP-2) and markers of MM burden. Baseline serum transgelin was also evaluated as a predictor of kidney function after a follow-up of 27 months from the start of the study. Significant correlations were detected between serum transgelin-2 and serum creatinine (R = 0.29; p = 0.001) and eGFR (R = −0.25; p = 0.007). Transgelin significantly correlated with serum free light chains lambda (R = 0.18; p = 0.047) and serum periostin (R = −0.22; p = 0.013), after exclusion of smoldering MM patients. Patients with decreasing eGFR had higher transgelin levels (median 106.6 versus 83.9 ng/mL), although the difference was marginally significant (p = 0.05). However, baseline transgelin positively correlated with serum creatinine after the follow-up period (R = 0.37; p < 0.001) and negatively correlated with eGFR after the follow-up period (R = −0.33; p < 0.001). Moreover, higher baseline serum transgelin (beta = −0.11 ± 0.05; p = 0.032) significantly predicted lower eGFR values after the follow-up period, irrespective of baseline eGFR and follow-up duration. Our study shows for the first time that elevated serum transgelin is negatively associated with glomerular filtration in MM and predicts a decline in renal function over long-term follow-up.

Abstract Background and Aims Transcatheter aortic valve implantation (TAVI) is indicated for the treatment of patients with severe aortic stenosis with a high surgical risk that are rejected for surgical valve placement. The aim of this study is to evaluate the effect of TAVI on long-term kidney function in stage 3-4 chronic kidney disease (CKD) patients. Method We performed a single-center retrospective observational study of 529 consecutive patients that underwent TAVI between August 2007 and January 2018. We included patients with stage 3 or 4 CKD, with at least two stable measurements of glomerular filtration rate during the three months before TAVI. We excluded patients that presented with an acute kidney injury during the three months that preceded TAVI. Results 165 patients (31.3%) of the patients who underwent TAVI had a stable stage 3 or 4 CKD before implantation. Their mean age was 83.61 ±5.08 years, BMI of 27.79 ± 4.54 kg/m2, baseline serum creatinine of 1.62 ± 0.49 mg/dl for an eGFR measured by MDRD-4 of 40.19 ± 10.79 ml/min, EuroScore-II of 6 (IQR 4-8). 42 patients (28.6%) had a post-procedural acute kidney injury (AKI), 2 of them required temporary renal replacement therapy and 30 patients (71.4%) recovered to their baseline kidney function. Mean contrast media administered was 162.0 ±77.8 ml. Mean serum creatinine decreased from 1.64 ± 0.51 mg/dl to 1.46 ± 0.52 ml/min after 1 year of follow-up (p=0.032). Only 2.4% of patients showed a &gt;50% increase in serum creatinine after 1 year. Median follow-up was 3.8 years (IQR 2.3-5.7 years) during which time no patient progressed to end-stage kidney disease. 33.3 % of patients died during follow-up, with a one-year survival rate of 87% and two-year survival of 82%. Post-interventional major bleeding (14.6 vs 5.8%, p&lt;0.001) and the need for post-interventional pacemaker implantation (25 vs 13.3%, p&lt;0,001)were the only risk factors associated with the development of AKI. Contrast volume was not associated with the development of AKI. AKI was associated with an increased in-hospital stay (13.2 vs 7.4 days, p&lt;0.001), but was not associated with either a reduced kidney function at end of follow-up or an increased mortality (Log-rank X2=1.72, p=0,578). Conclusion Despite the high incidence of post-interventional AKI after TAVI, our study did not show an association between AKI and increased mortality or reduced renal survival. In most cases after AKI patients recovered to their baseline kidney function. There is an improvement in kidney function after one year of treatment of severe aortic stenosis with TAVI in patients with CKD Stage 3-4.

Objective. The article discusses the problem of assessing renal function of the kidneys in premature babies born as a result of prematurely premature births with extremely low birth weight. Materials and methods. The functional state of the kidneys was evaluated in 148 children with ELBW and VLBW in the period from 1 to 90 days of postnatal age. The urine output rate, serum creatinine level, GFR calculation according to the Schwartz formula. Results. The results of the study showed that premature babies with ELBW are characterized by elevated serum creatinine levels and a low glomerular filtration rate, starting from the 4th day of life. An increase in GFR from the 3rd week of postnatal life significantly increases the likelihood of survival of premature babies with ELBW. The decrease in glomerular filtration rate in this contingent of children is associated not so much with kidney damage, but rather due to a more pronounced immaturity of nephrons Conclusion: Kidney function in preterm infants with ENMT is much lower than even in more mature children with ONHT. This is confirmed by high persistent levels of creatinine in serum and low SCF values throughout the neonatal period of life.

Abstract Background and Aims The aim of the study was to analyse the utility of retinol binding protein (RBP) in case of renal impairment in MM patients and investigate its relationship with acclaimed parameters of renal failure and markers of MM stages. Method We recruited 73 patients (35 women, 38 men, in age range of 29-90 years, mean 70 ± 10 years) with multiple myeloma (MM), including 6 (8%) with smoldering MM, 40 (55%) with International Staging System (ISS) stage I, 15 (21%) with ISS II and 12 (16%) with ISS III. The majority of patients (65, 89%) received at least one treatment scheme. Thirty patients (41%) received maintenance treatment at recruitment. Median eGFR based on serum creatinine (CKD-EPICr) equaled 67 (range 9 – 117) ml/min/1.73 m2. Results Significant correlation was observed between RBP and the ordered variable describing MM stage from smoldering myeloma to ISS III (R=0.36; p=0.002). There were no differences between patients in CR, PR, SD and PD at the time of samples’ collection. Patients who were on maintenance treatment at recruitment tended to have higher serum RBP (median 42.6 versus 37.7 mg/l), however, the difference was not statistically significant (p=0.068). The patients who received steroid treatment had significantly higher RBP concentrations. There were no such association with other medications. There was no association between RBP and the number of previous treatment lines (p=0.8). Serum RBP did not differ between men and women (p=0.7) and did not correlate with age (p=0.6). Significant correlations were found between RBP and serum creatinine, cystatin C and eGFR values calculated based on creatinine and/or cystatin C (Table 1). In multiple regression, serum creatinine or cystatin C and the treatment with steroids were associated with RBP independently of ISS stage (Table 2). Moreover, RBP correlated with β2-microglobulin, LDH, leukocyte count, α-klotho, FGF-23, GDF-15, uNGAL and uIGFBP-7, however, only the associations with β2-microglobulin and sTfR were independent of serum creatinine in multiple regression (Table 1). Baseline serum RBP concentration was significantly correlated with eGFR after a median of 19 months follow-up (range 1-24 months) (R=-0.35; p=0.003), however, the correlation was not independent of baseline serum creatinine ((beta ± SE: 0.06 ± 0.10; p=0.5). To the contrary, baseline serum cystatin C (beta ± SE: -0.36 ± 0.13; p=0.009) predicted final eGFR independently of baseline serum creatinine. Conclusion RBP may be useful marker in renal damage in patients with chronic kidney injury among patients with MM. This can lead to noninvasive biomarker-targeted diagnostic interventions and contribute to early beginning of treatment that may improve life expectancy quality of life in MM.

Functional Reserve

Serum creatinine and glomerular filtration rate (GFR) are the current standard tests tomeasure kidney function. The baseline GFR does not reflect full function of the kidney sincehuman kidneys do not always work at full capacity. Similarly, serum creatinine is not a sensitivemeasure for kidney function or injury. In healthy individuals the GFR physiologically increasesin response to certain stresses or stimuli, such as protein loading.Renal functional reserve (RFR) is defined as the difference between the maximalglomerular filtration rate (generally determined after oral or intravenous protein loading) and thebaseline glomerular filtration rate. The absence of a normal RFR can help identify patients whoare more susceptible to kidney injury. The RFR is also important in patients who develop acutekidney injury and chronic kidney disease. Even though the GFR might return to a baselinelevel, there may be some loss of RFR which can make the patient more susceptible to anotherepisode of kidney injury.Acute kidney injury and chronic kidney disease are considered interconnected syndromes;each is a risk factor for the other. There are no current recommendations regarding theperformance of routine determinations of RFR. Physicians should focus on clinical history andphysical examination in patients with a history of prior episodes of acute kidney injury, monitorrenal function, and avoid nephrotoxic insults.

Transient Elevation

Background: Serum Creatinine (SCr) is the most widely used parameter in clinical practice to estimate glomerular filtration rate (GFR). Various drugs have been reported to cause a reversible and transient elevation in SCr without a true reduction in overall kidney function Case Presentation: We describe a case of a 66-year-old-woman with right breast poorly differentiated invasive ductal carcinoma, hormone receptor positive and HER2 negative who received treatment with fulvestrant and palbociclib. The initial dose of Palbociclib was 125 mg orally a day, then reduce to 100 mg orally a day. She presented for evaluation of elevated serum creatinine with decreased eGFR. Upon evaluation an estimated glomerular filtration rate by cystatin C showed kidney function at her baseline for the past year. Conclusion: Palbocicib is a selective inhibitor of the cyclin-dependent kinases CDK4 and CDK6. Physicians should be aware that patients undergoing therapy with palbociclib require monitoring of kidney function and an increase in serum creatinine from baseline, might represent an inhibitory effect of the secretion of creatinine.

Abstract BackgroundThe presence of acute kidney injury (AKI) in pre-eclampsia complicates treatment including; increasing length of hospital stay and a need to access services like dialysis which are largely expensive in resource-limited settings. We aimed to determine incidence and predictors of acute kidney injury among women with severe pre-eclampsia at Mbarara Regional Referral Hospital in southwestern Uganda. MethodsWe carried out a hospital-based prospective cohort study from 16 November 2018 to 18 April 2019, among pregnant women with severe preeclampsia followed up in the hospital. We enrolled 70 mothers with severe pre-eclampsia and eclampsia; we excluded patients with a history of chronic renal disease, chronic hypertension, and gestational hypertension.Data on socio-demographics, laboratory parameters, health system, obstetric and medical factors were collected. Baseline serum creatinine, complete blood count, and CD4 T-cell count were all done at admission (0-hour). Second serum creatinine was done at 48-hours to determine the presence of AKI. AKI was defined as a rise in serum creatinine of 0.3mg/dl or more from the baseline. The proportion of women diagnosed with acute kidney injury among the total number of women with severe pre-eclampsia was reported as incidence proportion. Univariate and multivariate logistic regression was used to establish the association of acute kidney injury and severe pre-eclampsia.ResultsIncidence of acute kidney injury was high (41.4%) among women with severe pre-eclampsia. Antenatal care attendance was protective 0.36 (0.16, 0.80), p<0.013 at bivariate analysis but had no statistical significance at multivariate analysis. Eclampsia was an independent risk factor for acute kidney injury. (aRR 2.74 (1.06, 7.08), P<0. 037.ConclusionThe incidence of acute kidney injury in patients with preeclampsia is high. Eclampsia is an independent risk factor of acute kidney injury.
