Predicting hospital mortality in COVID-19 hemodialysis patients with developed scores.

Various risk scores such as COVID-GRAM Critical Illness Risk Score (COVID-GRAM), quick COVID-19 Severity Index (qCSI), and systemic immune-inflammation index (SII) have been developed to determine critical illness in hospitalized patients. None of these risk scoring systems was evaluated in HD patients who indeed carry the highest risk of developing critical illnesses. We aimed to evaluate, in hemodialysis (HD) patients with COVID-19, the performance of these scoring systems for the need of intensive care unit (ICU) and mortality. The qCSI, COVID-GRAM, and SII scores of the patients at admission to hospital were calculated and grouped according to the scoring results. The primary outcome of the study was mortality and need of ICU. Critical illness was described as a composition of admission to the ICU, invasive ventilation, or death. It was determined that when the qCSI is over 6.5, the need for ICU increased 13.8 times and mortality increased 21.3 times. When the COVID-GRAM score is >157, the ICU need increased 14.7 times and the mortality increased 33.7 times. We found that the need for ICU increased 4.2 times and mortality increased 3.1 times when the SII score was >1145. These tests, which can be easily calculated, could be used to estimate the risk of developing critical illness among COVID-19 HD patients. Estimating the risk of critical illness could help to reduce mortality in HD patients.

The value of C-reactive protein in infection diagnosis and prognosis in elderly patients.

BACKGROUND: The aim of this study was to determine the value of C-reactive protein level in the diagnosis and prognosis of infection in elderly patients. STUDY POPULATION: This prospective study included inpatients in the palliative care unit during the 1-year period between January 2016 and January 2017. Patients' demographic data, Acute Physiology and Chronic Health Evaluation score, and Charlson Comorbidity Index were recorded. RESULTS: A total of 233 patients were included in the study. A total of 199 instances of infection were diagnosed in 175 of those patients; 75.3% of the infections were detected at admission and 24.7% during hospitalization. At a cut-off value of 4.82, CRP value had 81.0% specificity and 75.4% sensitivity in the diagnosis of infection. Among the patients with infection, there was no difference between those who died and those who survived in terms of baseline CRP level, but a significant difference emerged in CRP level at 48 and 96 h. Factors which were found to significantly reduce survival time were the presence of chronic kidney disease, chronic obstructive pulmonary disease, hypoxia and tachycardia at admission, APACHE-II score over 20.5, initial albumin level below 2.44 g/dL, and serum CRP clearance rates of less than 11% at 48 h and 20% at 96 h. CONCLUSION: In elderly patients with infection, the initial CRP value alone does not have prognostic value, but changes observed in serial CRP measurement are a valid indicator of prognosis.

Comparison of QuantiFERON-TB gold in-tube test with tuberculin skin test in children who had no contact with active tuberculosis case.

INTRODUCTION: In this study, we aimed to compare QuantiFERON-TB gold in-tube test (QFT-GIT) and tuberculin skin test (TST) as a diagnosis of latent tuberculosis infection in the children with Bacille Calmette-Guerin (BCG) vaccine. MATERIALS AND METHODS: We evaluated 81 children in the study who have positive TST result without a known history of tuberculosis contact from 2008 to 2011 prospectively. Patients were separated into groups according to their ages, the reason of TST application, number of BCG vaccination scars and diameter of TST induration. Posteroanterior, lateral chest radiographies and computerized tomography, if necessary, were performed. RESULTS: The study consists of 48 (59.3%) boys and 33 (40.7%) girls with a mean age of 94.8 ± 51.9 months (ranged from 6 to 193 months). Sixty nine (85.2%) children had one and 12 (14.8%) had two BCG vaccination scars. The TST induration diameters were 15-19 mm in 65 (80.2%) children and ≥ 20 mm in 16 (19.8%) children. QFT-GIT positivity was found in 12 (14.8%) of the evaluated patients. QFT-GIT positive patients were treated with triple anti-tuberculosis regime or isoniazid (INH). In three years period of study, there were no tuberculosis disease observed among the children who had not been treated with anti-tuberculosis drugs. CONCLUSION: As a result of the study it is suggested to confirm positive TST results with tests based on interferon-gamma (IFN-γ) because it can reduce false positive diagnosis and treatment of latent tuberculosis infection, thus adverse reactions of drugs, in countries where BCG vaccination is routinely recommended especially for low risk children.

The effect of a multispecies synbiotic mixture on the duration of diarrhea and length of hospital stay in children with acute diarrhea in Turkey: single blinded randomized study.

Probiotics have been successfully used for the treatment of acute diarrhea in children and this effect depends on the strains and dose. The aim of this study was to assess the effect of a synbiotic mixture on the duration of diarrhea and the length of hospital stay in children with acute watery diarrhea. This is a prospective randomized, multicenter single blinded clinical trial in hospitalized children with acute watery diarrhea. All children were treated with conventional hydration therapy with or without a daily dose of a synbiotic (2.5 × 10(9) CFU live bacteria including Lactobacillus acidophilus, Lactobacillus rhamnosus, Bifidobacterium bifidum, Bifidobacterium longum, Enterococcus faecium, and 625 mg fructooligosaccharide) for 5 days. The primary endpoint was duration of diarrhea and duration of hospitalization was the secondary endpoint. Among 209 eligible children, 113 received the synbiotic mixture and 96 served as a control. The duration of diarrhea was significantly shorter (∼36 h) in children receiving the synbiotic group than the controls (77.9 ± 30.5 vs. 114.6 ± 37.4 h, p < 0.0001). The duration of hospitalization was shorter in children receiving the synbiotic group (4.94 ± 1.7 vs. 5.77 ± 1.97 days, p = 0.002). The effect of synbiotic mixture on diarrhea started after 24th hours and stool frequency significantly decreased after 24th and 48th hours. The percentage of diarrhea-free children is significantly higher in synbiotic group at 48th and 72nd hours of synbiotic group. In conclusion, this study showed a reduction in diarrhea duration by approximately 36 h and a reduction in the duration of hospitalization with approximately 1 day in children with acute diarrhea with this synbiotic mixture.

The effects of mycophenolate mofetil on encapsulated peritoneal sclerosis model in rats.

INTRODUCTION: Encapsulated peritoneal sclerosis (EPS) is a devastating complication of peritoneal dialysis. We aimed to investigate the effects of mycophenolate mofetil (MMF) treatment in experimental EPS in rats. METHODS: 40 nonuremic Wistar albino rats were divided equally into 4 groups: control rats received 2 ml isotonic saline intraperitoneally daily for 3 weeks without any other treatment. The chlorhexidine gluconate group received intraperitoneally 2 ml/200 g injection of chlorhexidine gluconate and ethanol dissolved in saline for 3 weeks. The resting group received chlorhexidine gluconate (0 - 3rd week) + peritoneal resting (4th - 6th week). The MMF group received chlorhexidine gluconate (0 - 3rd week) + 125 mg/l MMF in drinking water (4th - 6th week). Dialysate cytokine levels, leukocyte count, peritoneal thickness, inflammation and fibroblast activities were evaluated. RESULTS: Although the MMF and resting groups showed beneficial effects on ultrafiltration and D1/D0 glucose compared to the chlorhexidine gluconate group, only MMF treatment improved dialysate TGFß1, VEGF and MCP-1 levels compared to the resting group. Inflammatory activity and vascularity observed in a tissue biopsy, including capillaries number per mm2 of submesothelial area, decreased in the treatment group. CONCLUSIONS: MMF treatment has beneficial effects on EPS via inhibiting inflammation and neovascularisation by reducing dialysate VEGF overexpression.

Octreotide lessens peritoneal injury in experimental encapsulated peritoneal sclerosis model.

AIM: Encapsulated peritoneal sclerosis is characterized by neoangiogenesis and fibrosis. Octreotide, a somatostatin analogue is a well-known antifibrotic, antiproliferative and anti-angiogenic agent. The aim of the study is to evaluate the effects of octreotide in encapsulated peritoneal sclerosis-induced neoangiogenesis and fibrosis and compare the results with resting. METHODS: Non-uraemic Wistar-Albino male rats (n = 35) were divided into four groups. Group I, control rats, received 2 mL isotonic saline i.p. daily for 3 weeks. Group II, received daily i.p. 2 mL/200 g injection of chlorhexidine gluconate (0.1%) and ethanol (%15) dissolved in saline for 3 weeks. Group III, chlorhexidine gluconate for 3 weeks plus an additional 3 weeks without any treatment (rest), to a total of 6 weeks. Group IV, chlorhexidine gluconate for 3 weeks plus an additional 3 weeks octreotide, 50 mcg/kg bodyweight s.c., for a total of 6 weeks. RESULTS: Octreotide significantly reversed ultrafiltration capacity of peritoneum with decreasing inflammation, neoangiogenesis and fibrosis compared to the resting group. Octreotide also caused inhibition of dialysate transforming growth factor-ß1, vascular endothelial growth factor and monocyte chemotactic protein-1 activity and improved mesothelial cell cytokeratin expression. Peritoneal resting has no beneficial effects on peritoneum. CONCLUSION: In conclusion, octreotide may have a therapeutic value in peritoneal dialysis patients who suffer from encapsulated peritoneal sclerosis.

What does the dialysate level of matrix metalloproteinase 2 tell us?

Long-term peritoneal dialysis leads to encapsulating peritoneal sclerosis (EPS), which is a rare but often fatal complication. The pathogenesis of EPS is characterized by increased inflammation, neoangiogenesis, epithelial-mesenchymal transition (EMT), and fibrosis. Matrix metalloproteinase 2 (MMP-2), which degrades type IV collagen, plays an important role in pathogenesis. Clinical trials report that dialysate levels of MMP-2 can be used as an early marker of peritoneal sclerosis. We aimed to determine the association of MMP-2 with peritoneal function, histology, and effluent cytokine levels in an experimental EPS model in rats. We evaluated data for 71 rats from our various studies using an experimental EPS model. Functional assessment was performed using a 1-hour peritoneal equilibration test with peritoneal dialysis fluid containing 3.86% glucose. Specimens of parietal peritoneum were examined with light microscopy for histologic evaluation. Parietal peritoneum thickness and submesothelial area were measured. Fibrosis, number of vessels, neovascularization, and cellular infiltration were evaluated by one pathologist. The relationships between MMP-2 and other parameters were analyzed using Pearson correlation analysis. Dialysate levels of MMP-2 reflect both functional and histologic change in peritoneum. Levels of MMP-2 were negatively correlated with net ultrafiltration, effluent protein levels, and end (1-hour)-to-initial dialysate concentration ratio of glucose. Cytokines such as vascular endothelial growth factor transforming growth factor beta, monocyte chemotactic protein 1, and osteopontin-which are known to play important roles in neovascularization, inflammation, and EMT leading to fibrosis-were correlated with MMP-2. In peritoneal dialysis patients, MMP-2 levels may be an early marker of EPS and EMT

Relationship between Sarcopenia and Mortality in Elderly Inpatients.

OBJECTIVE: Sarcopenia, a geriatric syndrome, is an indicator of poor prognosis in elderly inpatients. In this study, we aimed to determine the effect of sarcopenia on mortality in elderly patients. MATERIALS AND METHODS: Mobile/immobile geriatric inpatients, treated in the internal medicine ward between February and November 2018, were included in the study between Days 2 and 7 of hospitalization. The patients' fat-free mass (FFM) was measured by bioimpedance. The FFM index (FFMI) (kg/m2) was determined by dividing fat-free mass by body surface area (FFM/BSA). Sarcopenia was defined as a FFMI value at least two standard deviations below the gender-specific mean of normal young adults. RESULTS: The study included 200 geriatric inpatients; 96 (48.0%) were men, and the mean age was 74.49±6.32 years. Sarcopenia was detected in 28 (14%) of the patients. Diabetes mellitus was associated with a significantly lower sarcopenia prevalence (p=0.006). The risk of sarcopenia was 9.046 times higher in malnourished patients. The sarcopenia group had more deaths (p=0.012). CONCLUSION: Sarcopenia in geriatric inpatients increased the length of hospital stay and mortality. Our findings may guide future studies examining the relationship between sarcopenia and mortality among elderly inpatients in other hospitals.

Primary skeletal muscle lymphoma: A case report.

Primary lymphomas of the bone or skeletal muscle are rare. Three mechanisms of lymphomatous involvement of the muscle have been described, namely direct invasion from adjacent involved lymph nodes or bone, metastatic spread and, least commonly, primary muscle lymphoma. We herein present a rare case of primary mucle non-Hodgkin lymphoma with a description if the associated clinicopathological findings and a review of the relevant literature. A 41-year-old female patient was referred to our hospital with a painful mass in the right lower extremity. Following resection and histopathological examination, a diffuse large B-cell lymphoma originating from the muscle with cutaneous and subcutanenous infiltration was diagnosed. The patient received chemotherapy with six cycles of cyclophosphamide, hydroxydaunomycin, oncovin and prednisone (CHOP regimen) and a complete radiological response was achieved after six cycles of treatment.

High C-Reactive Protein and Low Albumin Levels Predict High 30-Day Mortality in Patients Undergoing Percutaneous Endoscopic Gastrotomy.

BACKGROUND: Percutaneous endoscopic gastrotomy (PEG) enables long-term enteral feeding. The aim of this study was to identify biomarkers that may guide the decision of whether to perform the elective procedure of PEG. METHODS: The medical records of all patients who underwent PEG in our hospital from 2010 to 2016 were screened retrospectively. Patients with mortality within a 30-day follow-up period and those without were compared using the Chi-square test, and continuous variables were compared with the Kruskal-Wallis and Mann-Whitney U tests. Receiver operating characteristic (ROC) curve analysis was used to demonstrate the ability of biomarkers to predict mortality; a cut-off point was determined and its sensitivity, specificity, and positive and negative predictive values were calculated. The Youden index was used to determine the cut-off point. Kaplan-Meier analysis was used to identify PEG-related mortality risk factors and a Cox regression model was applied for risk characterization. RESULTS: A total of 120 patients who underwent PEG were evaluated in the study. The mean age was 67.00 ± 18.00 years. The most common indication for PEG was cerebrovascular disease, in 69 (57.5%) of the patients. Infection of the PEG site was most common within 14 days after PEG tube placement, occurring in 13 patients (10.3%). The mortality rate among patients with post-PEG infection was 68.2%, significantly higher than in patients without infection (P = 0.012). Thirty-four patients (28.3%) died within 30 days of undergoing PEG. CRP values ≥ 78.31 mg/L increased mortality by 8.756-fold, and albumin levels < 2.71 g/dL increased mortality by 2.255-fold. CONCLUSION: Our results indicate that the presence of both high CRP level and low albumin level were associated with significantly higher rate of mortality (73.1%) in patients who underwent PEG.

Autopsies in the elderly: Erzurum study.

INTRODUCTION: Clinical and forensic autopsies are the best methods for determining cause of death. The aim of this study was to determine demographic and etiologic characteristics in geriatric forensic cases analyzed in Erzurum, Turkey. MATERIALS AND METHODS: Autopsy reports and prosecution documents of decedents aged 65 and older autopsied in the Morgue Specialization Department of the Forensic Medicine Institute, Erzurum Division between January 1, 2010 and December 31, 2015 were screened retrospectively. RESULTS: The study included 399 subjects with a mean age of 74.38 ± 7.28 years. A large proportion of the subjects were in the young and middle old age group (n = 218, 54.63%) and male (n = 286, 71.68%). Autopsy was performed on 198 (49.62%) of the subjects, cause of death was determined by post-mortem external examination in 199 (49.87%), and documents were unavailable for 2 subjects. Cause of death was determined as natural in 130 (32.58%) of the decedents and unnatural in 269 (67.42%). The most common natural cause of death was cardiovascular disease (n = 94, 76.4%). Unnatural causes of death included accident in 223 (82.90%), suicide in 25 (9.30%) and homicide in 21 (7.80%) of the decedents. A large proportion of the accidents were traffic accidents (n = 120, 53.80%). The most common method of committing suicide was hanging (n = 15, 60%), whereas homicides were most often committed by blunt force trauma (n = 9, 42.86%). CONCLUSION: Our data are consistent with the literature, allowing for some variation based on regional sociocultural characteristics.

Mean platelet volume in euthyroid patients with Hashimoto's thyroiditis.

Mean platelet volume (MPV) is the measure of platelet size. MPV possibly is a simple way to estimate platelet activity. In this study, we aimed to investigate MPV levels in euthyroid Hashimoto's thyroiditis patients. Fifty-one euthyroid patients with Hashimoto's thyroiditis attending our outpatient clinic of the endocrinology department, and 51 age and BMI-matched healthy individuals were included in this study. All patients with euthyroid Hashimoto's thyroiditis were at euthyroid state. None of the study patients was subjected to levothyroxine replacement therapy. Anti-thyroid peroxidase (anti-TPO) antibody and anti-tiroglobulin antibody were positive. All the study participants were evaluated by biochemical and platelet parameters. There were no significant differences in age (33.88 ±â€Š12.87 and 30.18 ±â€Š12.43 years, respectively; P > 0.05) and BMI (23.55 ±â€Š3.34 and 22.25 ±â€Š3.65 kg/m, respectively, P > 0.05) between the study and the control groups. Anti-TPO and anti-tiroglobulin levels were significantly higher in the study group (anti-TPO 428.32 ±â€Š668.39 IU/ml in the euthyroid Hashimoto's thyroiditis group; 14.85 ±â€Š9.66 IU/ml in the control group, P = 0.001; anti-tiroglobulin 320.46 ±â€Š796.05 IU/ml in the euthyroid Hashimoto's thyroiditis group, 21.28 ±â€Š26.24 IU/ml in the control group, P = 0.09). There were no significant differences in terms of serum thyroid-stimulating hormone (TSH) (1.76 ±â€Š0.79 and 1.85 ±â€Š1.14 uIU/ml, respectively), FT3 (3.10 ±â€Š0.37 and 3.29 ±â€Š0.76 pg/ml, respectively) and FT4 (1.22 ±â€Š0.42 and 1.46 ±â€Š0.78 pg/ml, respectively) levels between the study and the control groups. Serum triglyceride levels were significantly higher in the study group than in the control group (133.81 ±â€Š91.50 and 90.18 ±â€Š41.15 mg/dl, respectively; P = 0.015). Mean MPV levels were significantly higher in the euthyroid Hashimoto's thyroiditis group than in the control patients (8.8 ±â€Š1.05 and 7.9 ±â€Š0.79 fl, respectively; P = 0.0001). To assess the correlation with MPV, a Pearson's correlation analysis was performed on each variable. There were positive correlations between anti-TPO and MPV levels (r = 0.246, P = 0.042), and between anti-tiroglobulin and MPV levels (r = 0.256, P = 0.033). The multiple regression analysis of MPV and other risk factors was performed. Age, BMI, C-reactive protein and waist circumference were independent predictive factors of MPV. Adjustment for other factors did not alter these relative risks. Our results suggest that even if in euthyroid state, patients with euthyroid Hashimoto's thyroiditis have higher MPV levels than the healthy controls. As higher MPV levels are closely related with cardiovascular diseases, euthyroid Hashimoto's thyroiditis patients have greater risk of atherothrombotic complications than controls.

[Three Pediatric Cases of Leishmaniasis with Different Clinical Forms and Treatment Regimens]. / Klinik Formlari ve Tedavi Rejimleri Farkli Üç Pediyatrik Leishmaniasis Olgusu.

Several clinical syndromes caused by an obligate intracellular parasite Leishmania spp. subsumed under the term leishmaniasis. Leishmaniasis is endemic in Turkey and the neighboring countries Iran, Iraq, and Syria. Leishmania spp. causes three main clinical forms: cutaneous, mucocutaneous, and visceral disease. The clinical forms may vary by species and/or region of acquisition. Two forms are observed in Turkey; visceral leishmaniasis and cutaneous leishmaniasis. Two cases of cutaneous leishmaniasis with different treatment regimens and a case of visseral leishmaniasis associated with hemophagocytic lymphohistiocytosis are presented in this report.

[Coexistence of Pulmonary Hydatid Cyst and Mycoplasma pneumoniae Pnömonia in a Child]. / Akciger Kist Hidatigine Eslik Eden Mycoplasma pneumonia Pnömonili Çocuk Olgu .

Hydatid cyst is a zoonotic disease and endemic in Turkey. The disease can involve any organ. The most common involved organ is lung in childhood. Hydatid cyst of lung may be asymptomatic or may be sometimes ruptured or infected. Secondary bacterial infections associated with the hydatid cyst are well known. A previously not reported pediatric case of hydatid cyst with Mycoplasma pneumoniae pneumonia is described in this report. It is emphasized that M. pneumoniae should be kept in mind as a cause of infected hydatid cyst which is unresponsive to beta-laktam antibiotics.

Coexistence of liver hydatid cyst and brucellosis in an adolescent.

A 15-year-old girl, who was evaluated for arthralgia of knees, was diagnosed as having brucellosis by serum agglutination and enzyme linked immunosorbent assay tests. Physical examination of the patient revealed massive hepatomegaly. Abdominal ultrasonography and computerised tomography showed a single large cystic lesion of the liver. The echinococcus indirect haemagglutination was positive at a titre of 1/1280. A giant hydatid cyst was removed with surgical intervention; in addition, she was treated with albendazole and antibrucellosis drug combination with success. Here, an immunocompetent adolescent case with brucellosis and concomitant hydatid cyst disease was reported to emphasise that the coexistence of both entities are infrequent but may occur due to increased prevalence of the diseases.

Nosocomial infections in the general pediatric wards of a hospital in Turkey.

The aims of this study were to determine the prevalence, type, and clinical features of nosocomial infections (NIs), their etiological distribution, and the antibiotic resistance patterns of causative organisms in the general pediatric wards of a hospital in Turkey over a 3-year period. The Hospital Infection Control Committee NI surveillance reports were used as a database. NIs were detected in 171 (2.25%) of the 7,594 hospitalized patients. Some of these patients experienced more than 1 episode, and thus, the total NI episodes were 229. Patients' age varied from 1 to 144 months (mean ± standard deviation, 14.5 ± 23.6 months). The NI rate was 3.02%, and the NI density was 3.17/1,000 patient days. The most frequent NIs were lower respiratory system infections, blood stream infections, and urinary tract infections. Gram-negative organisms were the most frequently isolated agents. Of the 171 patients with NIs, 47 (27.5%) died.

The clinical characteristics and treatment of pertussis patients in a tertiary center over a four-year period.

We performed a retrospective study of pertussis patients seen during the period July 2007-December 2011. All patients were microbiologically confirmed through polymerase chain reaction (PCR) or culture. Thirty one patients with positive Bordetella spp. culture or PCR were identified, with a median age of two months. Seventeen patients had received no pertussis vaccination. The most frequent symptoms were paroxysmal cough (100%) and cyanosis (87.1%). The mean duration of the symptoms prior to admission was 12.8 ± 8.0 days. Leukocytosis and thrombocytosis were detected in 64.3% and 67.9% of the 28 hospitalized patients, respectively. Erythromycin had been given to eight patients and clarithromycin to 23 patients. The mean hospital stay was 9.5 ± 5.5 days (range: 3 to 28 days). No patients were readmitted or died. We believe that patients with characteristic paroxysmal cough with cyanosis but no fever should alert clinicians to the possibility of pertussis, and they should be treated without delay. PCR assay provided additional benefit in the diagnoses of the study patients.

A novel angiogenesis inhibitor, sunitinib malate, in encapsulating peritoneal sclerosis.

INTRODUCTION: Encapsulated peritoneal sclerosis (EPS) is characterized by neoangiogenesis and fibrosis. Increased inflammation is the leading cause of EPS. In turn, neoangiogenesis is both a consequence of and contributor to inflammation. The effects of sunitinib, a multitargeted receptor tyrosine kinase inhibitor, have been postulated in various antiangiogenesis, antiinflammatory and antifibrotic processes both in vitro and in vivo. This novel angiogenesis inhibitor, Sutent (sunitinib malate), was investigated in our rat EPS model. MATERIALS AND METHODS: Forty nonuremic Wistar albino rats were divided into 4 groups as follows: 2-mL isotonic saline intraperitoneally (i.p.) daily, for 3 weeks (control group); daily 2 ml/200 g injection i.p. of chlorhexidine gluconate (0.1%) and ethanol (15%) dissolved in saline, 3 weeks (CG group); CG + additional 3 weeks without any treatment, total 6 weeks (resting group); and CG + additional 3 weeks 1 mg/kg daily Sutent (SUT) in drinking water, total 6 weeks (SUT group). At the end of the study, 1-hour PET was performed. Functional parameters and morphological changes of peritoneum with dialysate cytokine levels were examined. RESULTS: SUT renewed ultrafiltration failure, D1/D0 glucose levels and dialysate protein loss. Peritoneal thickness, white blood cell count and inflammation of peritoneum were also decreased with SUT treatment. SUT significantly improved overexpression of dialysate transforming growth factor-ß1, monocyte chemoattractant protein-1 and vascular endothelial growth factor (VEGF) levels as compared with resting group. CONCLUSION: In conclusion, SUT might preserve membrane viability even at lower dosages. Although this is an experimental study, we believe that SUT after controlled trials may be a therapeutic agent for long-term peritoneal dialysis patients.
