The relationship between soluble Klotho (s-Klotho) levels, fibroblast growth factor 23 (FGF23) levels, and albuminuria in patients with diabetic chronic kidney disease (CKD) remains unclear. A total of 109 patients with type 2 diabetes (mean age 61.63±9.77 years), at the outpatient clinic of the Antalya Research and Training Hospital Nephrology Unit between January and June 2014, as well as 32 healthy controls (mean age 49.53±7.32 years) were enrolled for this cross-sectional study. Patients were classified into three groups according to their urinary albumin creatinine ratio (UACR), normoalbuminuria (UACR<30 mg/g), microalbuminuria (UACR 30-300 mg/g), and macroalbuminuria (UACR>300 mg/g). The blood was analyzed for FGF23, s-Klotho, parathyroid hormone (PTH), P, Ca, creatinine, and 25-hydroxyvitamin D3 (25hD) levels. Creatinine, s-Klotho, FGF23, and PTH levels were significantly higher and 25hD levels were significantly lower in the patient group than in the healthy controls (p<0.001). Between the groups according to UACR, 1-way analysis of variance revealed statistically significant differences for creatinine (p<0.001), 25hD (p<0.001), PTH (p=0.002), Ca (p=0.002), and albumin levels (p<0.001). A statistically significant positive correlation was found between s-Klotho and FGF23 (r=0.768; p=0.001), and between FGF23 levels and UACR (r=0.768; p=0.001). In conclusion, the results of the present study suggest that s-Klotho levels are significantly elevated in patients with diabetes and s-Klotho levels decreased with increasing albumin excretion in our patients despite a reduction in estimated glomerular filtration rate.
Background: The klotho (Klt)-fibroblast growth factor-23 (FGF-23)-vitamin D axis is the main component of calcium (Ca) and phosphorus (P) metabolisms; on the contrary, it is also secreted from the choroid plexus (CP). Purpose: This study is aimed at evaluating serum soluble Klt (sKlt), FGF-23, and 25-(OH)-vitamin D levels in multiple sclerosis (MS) patients. Methods: Thirty-two relapsing-remitting MS patients (11 males and 21 females; mean age 38.3 years) and 31 age-sex matched healthy controls (12 males and 19 females; median age 38.5 years) were included in this study. All patients were diagnosed with MS according to the criteria of McDonald. Results: Serum sKlt, FGF-23, and P levels were significantly higher in MS patients compared to the control group (p < 0.01, p < 0.01, and p = 0.02, respectively). Serum 25-(OH)-vitamin D and Ca levels were significantly lower in MS patients (p < 0.01 and p = 0.04, respectively). Conclusion: Klt, which is secreted from CP, could be a response to the inflammatory condition in MS. Elevated FGF-23 levels suppress 1α-hydroxylase and upregulates 24α-hydroxylase, which results in a decrease in 1,25-(OH)2D3 levels. Thus, the neuroprotective and immunomodulatory effects of vitamin D might not be seen in MS patients.
This study aims to determine fibroblast growth factor-23 and soluble α-Klotho levels in patients with autosomal dominant polycystic kidney disease. A total of 76 patients with autosomal dominant polycystic kidney disease and 32 healthy volunteers were included in the study. Serum fibroblast growth factor-23 and soluble α-Klotho levels were measured with ELISA kits. Parathyroid hormone, phosphate, calcium, creatinine, 25-hydroxyvitamin D3 levels, urinary protein to creatinine ratio and estimated glomerular filtration rate were also measured or calculated. Patients with autosomal dominant polycystic kidney disease had significantly higher serum parathyroid hormone (p<0.001), fibroblast growth factor-23 (p<0.001), soluble α-Klotho levels (p=0.001) and lower serum 25-hydroxyvitamin D3 levels (p<0.001) as compared with healthy volunteers. Serum fibroblast growth factor-23, soluble α-Klotho and 25-hydroxyvitamin D3 levels were similar in all five chronic kidney disease stages of autosomal dominant polycystic kidney disease (p>0.05). Fibroblast growth factor-23 (r=-0.251, p=0.034) and soluble α-Klotho levels (r=-0.251, p=0.034) were found to be negatively correlated with estimated glomerular filtration rate. This study shows increased fibroblast growth factor-23 levels in patients with autosomal dominant polycystic kidney disease which is in harmony with the general trend in patients with chronic kidney disease of other aetiologies, but, unlike them, also a significant increase in serum soluble α-Klotho levels in patients with autosomal dominant polycystic kidney disease suggesting an aberrant production or a decreased clearance of α-Klotho molecule. Considering the unique increases in erythropoietin levels due to erythropoietin production in renal cysts, we assume, patients with autosomal dominant polycystic kidney disease may potentially have different soluble α-Klotho production/clearance characteristics than the patients with other parenchymal renal diseases.
The genus of Cedecea was first isolated by the Centers for Disease Control (CDC) Laboratories in 1981 and designated as a separate genus in the Enterobacteriaceae family. They are Gram negative, lipase positive, non spore forming bacilli. This report presents the first case of urinary tract infection caused by Cedecea lapagei and a brief review of the literature including the reported infections that were caused by Cedecea spp. Forty years old male patient who had an operation for stabilization in brain surgery clinic after spinal cord injury and transferred to physical therapy clinic for rehabilitation, had a temperature of 38.5 o C on the 17th day of the injury and the following results were detected in laboratory examination: WBC 18900/mm³, CRP 345 mg/l and erythrocyte sedimentation rate 38 mm/h, abundant leukocytes and bacteria in urine examination. With the diagnosis of urinary tract infection, the patient was taken over to Infectious Diseases and Clinical Microbiology Clinic. In two consecutive urine cultures 100,000 CFU/ml Gram negative bacilli was isolated and identified as Cedecea lapagei with Phoenix automated system (BD Diagnostics, Sparcs, MD). Following the treatment with ciprofloxacin, his fever decreased on the second day and control urine culture was sterile. Nevertheless, the infections due to Cedecea spp. have been reported in the literature, this was the first urinary tract infection caused by Cedecea lapagei. Rare causes of urinary tract infection like Cedecea spp. should also be taken into consideration in long-term hospitalized patients.
Background: In patients with coronavirus disease 2019, the gastrointestinal symptoms have been reported increasingly in addition to the respiratory system symptoms. The studies show that the prevalence of gastrointestinal system symptoms and how the gastrointestinal system contributes to the severity and prognosis of the disease is still not clear. This study aims to find the prevalence of gastrointestinal symptoms and the correlation between the gastrointestinal symptoms and the clinical results in hospitalized patients diagnosed with coronavirus disease 2019. Methods: This study retrospectively analyzes patients diagnosed with coronavirus disease 2019 and hospitalized in the pandemic unit between March 2020 and August 2020 and compares their demographic and clinical characteristics, laboratory and radiologic findings, coronavirus disease 2019 treatments received, the clinical course of the disease, and the gastrointestinal symptoms. Results: In our study, we included 322 patients diagnosed with coronavirus disease 2019 and hospitalized; 39 patients (12.1%) were admitted to the hospital with at least one gastrointestinal symptom (nausea and vomiting, diarrhea, abdominal pain, and the loss of taste). Nausea and vomiting are the most common gastrointestinal symptoms with a prevalence of 7.1%, followed by diarrhea with 2.8%, the loss of taste with 2.2%, and abdominal pain with 1.5%. The mean age and D-dimer levels of the patients showing gastrointestinal symptoms were lower than those who did not have any gastrointestinal symptoms. We did not find a significant correlation between the presence of the gastrointestinal symptoms and the severity of the disease, treatment received, risk of acute respiratory distress syndrome and septic shock, admission to the intensive care unit, the need for mechanical ventilation, the mortality rate or the length of hospitalization in the medical floor or the intensive care unit. Conclusion: In this study, we observed that 12.1% of coronavirus disease 2019 patients apply to the hospital due to gastrointestinal symptoms. Furthermore, the gastrointestinal symptoms do not seem to affect the severity and the course of the disease, it is important to identify coronavirus disease 2019 patients showing unusual symptoms such as the gastrointestinal symptoms at an early stage to protect healthcare professionals from infection risk.
