Abstract Background Occurrence of acute oliguric renal failure in the immediate postoperative period carries important morbidity and mortality after a successful cardiac surgical procedure. Adult cardiac and aortic surgical procedures are especially prone to this complication with the incidence varying between 2% to 15% and the mortality rate as high as 40% to 60%. Aim of the Work to compare between furosemide versus mannitol as a renal protection after adult cardiac surgery. Patients and Methods This prospective comparative trial was conducted at Academy of Cardiothoracic Surgery Ain Shams University on patients undergoing CABG operation consisting of a total of 50 patients with normal renal function, EF of greater than 40%, normal protein and electrolyte levels. Results the study revealed no statistically significant difference between groups according to cystatin-C Conclusion The difference between patients given mannitol and patients given furosemide regarding urinary microalbumin, urinary creatinine and serum cystatin-c was insignificant. Addition of mannitol to the priming solution of the cardiopulmonary bypass acts as a renal protector against AKI postoperative. Finally, giving furosemide infusion to patients undergoing cardiac surgery at the beginning of the CPB improves renal perfusion.

Background: Cholangiocarcinoma (CCA) is the second most common primary hepatobiliary cancer. These patients have meager prognosis and short-term survival. Precise assessment of glomerular filtration rate is a fundamental aspect of clinical care in cancer patients. Cystatin C has been proposed to be superior to creatinine, a well-known marker of renal function. This study aimed to evaluate cystatin C as a marker of GFR calculation in CCA patients. Materials and Methods: One hundred thirty serum samples from CCA patients and 32 from controls were included in this study. Serum cystatin C was measured using immunoturbidity assay. Estimated glomerular filtration rate was calculated by three equations established by chronic kidney disease epidemiology collaboration (based on creatinine and/or cystatin C). Results: Serum cystatin C in CCA patients was higher than that of controls (p=0.0002). Cystatin C was positively correlated with BUN in CCA group (p=0.019). eGFR based on cystatin C and based on both cystatin C and creatinine in CCA was low with significantly different from those of control (p<0.001). Although there was no difference in eGFR using three equations in control, creatinine based eGFR was high with significantly different from eGFR based on cystatin C and on both creatinine and cystatin C in CCA (P=0.000). Proportion in each eGFR stage by three equations showed a high sensitivity with significantly different in CCA (p<0.05). Conclusion: There was a high sensitivity of cys C with significant difference between creatinine and/or cystatin C based eGFR in CCA patients. It should be taken into consideration of mild changes in eGFR by cystatin C which is important in managing drug dosage for CCA patients.

SummaryBackground:The aim of this study was to determine the level of serum cystatin C (CysC) in patients with Chronic Obstructive Pulmonary Disease (COPD) during exacerbation and stable periods and to investigate its potential diagnostic value and the relationship between CysC levels and the pulmonary function test (PFT).Methods:One hundred twenty-six patients with COPD (68 in stable periods, 58 during exacerbation periods) and 50 healthy subjects were included in the study. PFT, body mass index (BMI), white blood cell counts, C-reactive protein (CRP), serum urea and creatinine levels were evaluated in both groups of patients. CysC levels were measured in all participants.Results:Serum CysC levels were statistically higher in both COPD groups than the control group (p<0.001 for both) although there was no statistically significant difference between COPD groups (p>0.05). CysC levels showed negative correlation with forced expiratory volume in 1 second (FEV1) and a positive correlation with C-reactive protein (CRP) levels in patients with stable COPD. There was a positive correlation between serum CysC levels and serum urea, creatinine, CRP levels in patients with COPD exacerbation (r=0.333, p=0.011; r=0.260, p=0.049; r=0.414, p<0.01 respectively). When stable COPD and control groups were evaluated, serum CysC had an area under the curve (AUC) in the receiver operating characteristic (ROC) curve of 0.951 (0.909–0.994 95% CI: p<0.001).Conclusions:Our results showed that CysC levels increased in both COPD groups. Increased CysC levels may be related with lung function decline and inflammation in COPD patients. In addition, CysC levels may be a potential indicator for the diagnosis of COPD.

Purpose. Osteoporosis is a common age-related disorder leading to increased bone fragility and risk of fracture. Early diagnosis of osteoporosis is a vital step in providing early therapeutic intervention. Serum cystatin C is a marker of early renal dysfunction, a predictor of cardiovascular and inflammatory diseases, and an inhibitor of the differentiation of osteoclast precursor cells. The purpose of this study was to evaluate the relationship between serum cystatin C and osteoporosis. Methods. We enrolled 46 subjects who attended a health checkup and underwent measurement of bone status by quantitative ultrasound and determination of the level of serum cystatin C. A comparative study was conducted between those with and without osteoporosis for all subjects collectively and in two subgroups aged <65 and ≥65 years. Results. Serum cystatin C levels were strongly correlated with age, creatinine, and bone status data, with significant negative correlations with stiffness, T-score, and percentage of young adult mean. Among patients with osteoporosis, serum cystatin C was significantly higher even after adjustment for age and sex, whereas no significant difference was noted in creatinine. For patients aged ≥ 65 years, serum cystatin C was significantly higher in subjects with osteoporosis, although there was no significant difference in age between normal subjects and those with osteoporosis. Conclusions. To the best of our knowledge, this is the first study to demonstrate an association between serum cystatin C and osteoporosis. Serum cystatin C is significantly higher in osteoporosis and in particular may be a useful marker for osteoporosis among middle and elderly people aged ≥ 65 years. Measurement of serum cystatin C can be carried out easily and may contribute to early diagnosis and treatment of osteoporosis.

The objective is to examine and compare the usability of two physiotherapy programmes, analyzing respiratory function in patients before and after cardiac surgery in hospital during seven postoperative days (POD). Quantitative randomized prospective study of 157 patients before and after the valve replacement surgery, coronary artery bypass graft and combined surgeries, who moved independently. Participants were randomized into two groups (1 and 2) with different physiotherapy programmes. The routine physiotherapy of breath-enhancing techniques, micro-circulation improvement were used for the first group, for the second group - modified physiotherapy – the improvement of inspiration muscles, mm. quadriceps. gluteus max strength. Anthropometric measurements were defined for both groups on the day before surgery and during spirography - dynamic indicators - forced vital capacity (FVC), forced expiratory volume in the 2nd second (FEV1), Tiffeneau index (FEV1 / VC (%)), peak expiratory flow (PEF), operation parameters. By comparing the postoperative respiratory parameters between the two groups and using independent samples t test, it was found out that the difference in FVC between groups is 1.71 [95% CI: −8.25 to 4.8] and it is not statistically significant (t (155) = −0.52; p = 0.60). Based on the Leuven test results FVC the distribution variance is not statistically notably different for group 1 and group 2 (F = 0.27, p=0.60). Using routine and modified physiotherapy and comparing postoperative dynamic respiratory performance of the two groups, there was no statistically significant difference, proving that the two models are equally effective.

Introduction: Contrast-induced acute kidney injury (CI-AKI) is a known complication of cardiac interventions. Remote ischemic preconditioning (RIPC) is a non-pharmacological method which has a nephroprotective effect. Serum cystatin C (CysC) is a suitable biomarker for the early diagnosis of AKI. Objectives: This study aimed to evaluate the incidence of CI-AKI after RIPC in patients undergoing coronary angiography, through assessment of CysC. Patients and Methods: Around 140 patients with stable coronary artery disease undergoing angiography were randomly allocated to two groups of RIPC and control groups. In each group, the following biomarkers were assessed: serum creatinine (Cr) and CysC at baseline, 24-hour and 48-hour serum Cr and 24-hour CysC. The endpoint was the development of AKI based on either the KDIGO criteria or a 15% increase in serum CysC. Results: No significant difference was observed between two groups regarding the incidence of AKI according to either KIDIGO criteria or by the increase of serum CysC (P =0.116 and P =0.392, respectively). Moreover, a 46.99% increase in CysC level was observed among patients with AKI during the first 24 hours after the procedure, while at the same interval, it increased only 16.01% in patients without AKI. Conclusion: RIPC with three cycles of 5-minute ischemia and 5-minute reperfusion, did not decrease serum CysC based CI-AKI or alter renal biomarkers course in patients with low risk, who underwent coronary angiography.

AbstractBackgroundThe central role in the pathogenesis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), called as coronavirus disease 2019 (COVID-19), infection is attributed to angiotensin-converting enzyme 2 (ACE-2). ACE-2 expressing respiratory system involvement is the main clinical manifestation of the infection. However, literature about the association between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and higher ACE-2 expressing kidney is very limited. In this study, we primarily aimed to investigate whether there is a kidney injury during the course of SARS-CoV-2 infection. The predictive value of kidney injury for survival was also determined.MethodsA total of 47 participants who met the inclusion criteria were included in the study. The participants were classified as ‘‘COVID-19 patients before treatment’’ ‘‘COVID-19 patients after treatment’’, ‘‘COVID-19 patients under treatment in ICU’’ and ‘‘controls’’. The parameters comorbidity, serum creatinine and cystatin C levels, CKD-EPI eGFR levels, KIM-1 and NGAL levels, urine KIM-1/creatinine and NGAL/creatinine ratios were statistically compared between the groups. The associations between covariates including kidney disease indicators and death from COVID-19 were examined using Cox proportional hazard regression analysis.ResultsSerum creatinine and cystatin C levels, urine KIM-1/creatinine levels, and CKD-EPI, CKD-EPI cystatin C and CKD-EPI creatinine-cystatin C eGFR levels exhibited significant difference in the groups. The causes of the difference were more altered kidney function and increased acute kidney damage in COVID-19 patients before treatment and under treatment in ICU. Additionally, incidences of comorbidity and proteinuria in the urine analysis were higher in the COVID-19 patients under treatment in ICU group. Urine KIM-1/creatinine ratio and proteinuria were associated with COVID-19 specific death.ConclusionsWe found that COVID-19 patients under treatment in ICU exhibited extremely higher levels of serum cystatin C, and urine KIM-1/creatinine and urine NGAL/creatinine ratios. These results clearly described the acute kidney damage by COVID-19 using molecular kidney damage markers for the first time in the literature. Lowered CKD-EPI, CKD-EPI cystatin C and CKD-EPI creatinine-cystatin C eGFR levels were determined in them, as well. Urine KIM-1/creatinine ratio and proteinuria were associated with COVID-19 specific death. In this regard, considering kidney function and kidney damage markers must not be ignored in the COVID-19 patients, and serial monitoring of them should be considered.

In order to evaluate the early diagnosis value of CysC and the influence of mild hypothermia on the renal damage of asphyxia neonates, the serum cystatin C (CysC) levels of asphyxia neonates and normal neonates were measured by the nanomicrosphere-enhanced immunoturbidimetric method. The treatment was carried out, and the influence of mild hypothermia treatment on the renal damage of asphyxia neonates was analyzed. The results showed that the indicators of the asphyxia group were significantly higher than those of the control group, and the severe asphyxia group was significantly higher than that of the mild asphyxia group, which was statistically significant p < 0.05 ; the heart rate of patients in the mild hypothermia treatment group decreased gradually with the decrease in body temperature. And compared with the control group, there was a significant difference ( p < 0.05 ); after symptomatic treatment, the two groups of ALT, AST, BUN, and SCR were improved to varying degrees, and the difference was statistically significant compared with before treatment ( p < 0.05 ). Studies have shown that serum CysC level can be used as an indicator to detect glomerular filtration function and early asphyxia newborns, and it is sensitive and specific for early diagnosis of kidney damage. At the same time, it can be used to monitor clinical renal function and determine the status of asphyxia newborns.

The aim of the study – to determine the frequency of preeclampsia in pregnant females with anterior location of the placenta and to determine the prognostic significance when combined with a marker of acute renal damage – cystatin C level. Materials and Methods. In 2018–2020, a prospective cohort study that enrolled 91 pregnant women at their second trimester of gestation was conducted at Maternity Clinic and Obstetric Hospital of Maternity Hospital No. 2, Odesa. The group with the anterior location of the placenta consisted of 47 (51.65 %) pregnant women and 44 (48.35 %) had the posterior location of the placenta. Assessment of serum cystatin C was performed in women without clinical manifestations of PE at the second or third trimester of gestation (18–36 weeks), the average term was (32.22±0.41) weeks of pregnancy (p=0.011). Results and Discussion. 28.57 % of pregnant women were subsequently diagnosed with preeclampsia (PE), of whom 19 (20.88 %) had anterior and 7 (7.69 %) posterior placenta location. Body mass index (BMI) before pregnancy, age, and height: no statistically significant difference observed between groups (p> 0.05). Analysis of maternal factors of PE in relation to the anterior location of the placenta: odds ratio (OR) higher than 1.0 was noted for combination with obesity (OR 2.38 (95 % CI 0.75–7.53)), the age over 35 years (OR 1.01 (95 % CI 0.41–2.49)) and history of PE during previous pregnancy (OR 1.38 (95 % CI 0.21–9.01)), but no statistical significance was observed (р˃0.05). When analyzing cystatin C values over 1.0 mmol/l relative to the anterior location of the placenta, the OR was 3.92 (95 % CI 1.45–10.57), sensitivity 84.09 %, specificity 42.55 %, accuracy 62.64 % were reported, p=0.011. When analyzing the frequency of preeclampsia in the anterior location of the placenta, the OR was 3.59 (95 % CI 1.32 - 9.71), sensitivity 84.09 %, specificity 40.43 %, accuracy 61.54 % were reported with statistical significance p=0.019. Conclusions. The risk of preeclampsia in patients with the anterior location of the placenta increases by 3.59 times with a prognostic accuracy of 61.54 %. To increase the prognostic significance for the detection of preeclampsia in women with anterior location of the placenta, it is recommended to assess the serum level of cystatin C.
