RESUMEN

AIM: Treatment modalities of vesicoureteral reflux (VUR) consist of antimicrobial prophylaxis and antireflux surgery. In this study, we aimed to determine if antireflux surgery changes the course of renal functional deterioration in children with VUR and urinary tract infections (UTI). METHODS: Medical files of patients with VUR diagnosed during evaluation for UTI were evaluated retrospectively for gender, age, follow-up period, and renal ultrasonography (US) and serial 99mTc-dimercaptosuccinic acid (99mTc-DMSA) scintigraphy findings. Estimated glomerular filtration rate and urinary protein levels were determined at the initial and last visits, and before the operation in children who had antireflux surgery. The patients were divided into two groups as solely medically treated (Group 1) and both medically and surgically treated (Group 2). Group 2 was further divided as those with stable renal function (Group 2a) and with progressive renal injury (Group 2b). RESULTS: There were 140 patients (77 female; mean age 51.6 ± 51.9 months). Group 1 and Group 2 included 82 and 58 patients, respectively. In Group 2, the number of patients with the abnormal US, DMSA scintigraphy, and renal function was higher than in Group 1. Recurrent UTI rate was similar, but progressive scarring was more prominent in the antireflux surgery group. In Group 2, 31 patients had a stable renal function (Group 2a) while 27 had progressive deterioration of renal functions (Group 2b). These subgroups were not different with respect to the rate of high-grade VUR, the presence of a renal scar in DMSA, and UTI recurrence. However, the bilateral renal scar was more common in Group 2b. CONCLUSION: Antireflux surgery does not change the course of ongoing renal injury and renal functional deterioration.

RESUMEN

AIM: Sarcopenia is a progressive and generalized syndrome that can be linked to many causes such as cancers, and is caused by a quantitative and qualitative disorder (loss of muscle strength and/or physical performance) of skeletal muscle mass. Although sarcopenia has some hypothetical explanation in clinical practice, the mechanisms underlying this condition have not been clearly differentiated in patients with cancer. We aimed to investigate the relationship between irisin, FGF21 and CRP in detecting sarcopenia in colorectal cancer patients. MATERIAL AND METHODS: Current prospectively study included non-metastatic newly diagnosed colorectal cancer patients. Patients were divided into 2 groups of 25 people, those with and without sarcopenia. Body composition measurements by examined by BIA. To measure the level of iris and FGF21 from patients, blood samples were taken into the biochemistry tube and their levels were measured. RESULTS: The median age of the patients included in the study was 60 years (range: 21-81), 68% were men. It was found that there was a significant relationship between sarcopenia and gender and BMI measurement. When Spearman correlation analysis was performed between skeletal muscle mass index and FGF21, irisin and CRP, there was a positive correlation between skeletal muscle mass index and irisin and FGF21, while there was a negative correlation between skeletal muscle mass index and CRP. [respectively: (r: 0.282, p: 0.048), (r: 0.564, p: < 0.001) and (r: - 0.360, p: 0.010)]. Similar results were found between hand-grip strength and FGF21, irisin and CRP. [respectively: (r: 0.342, p: 0.015), (r: 0.290, p: 0.041) and (r: - 0.476, p < 0.001)]. When sarcopenia was treated as the dependent variable in the logistic regression analysis, and FGF21, irisin, CRP, gender and BMI were treated as the independent variables, irisin and CRP levels were determined as independent predictors. CONCLUSION: This study was revealed that there is a negative relationship between sarcopenia and irisin and FGF-21 in operated non-metastatic colorectal cancer patients and there may be a relationship between sarcopenia and inflammation. It suggests that these biomarkers may play a role in the pathophysiology of sarcopenia. However, our results need to be validated in different types of cancer and with more patients.
