Abstract Diabetes mellitus (DM) is a major cause of chronic kidney disease (CKD) and changes in lipoprotein. Literature data suggest that cholesterol associated with high-density lipoprotein (HDLc) plays a protective role against albuminuria and diabetic nephropathy. These factors are related with changes in serum apolipoproteins such Apo A-I. This work aims to evaluate the correlation of apolipoprotein A-I with renal function in diabetic outpatients. Samples were collected from 281 outpatients for analyses of glycated hemoglobin (HbA1c), serum creatinine (SCr), urea (BUN), cholesterol (TC), triglycerides (TG), HDL-cholesterol (HDLc) and estimation of glomerular filtration rate (eGFR). Urinary samples were obtained to assess urine albumin creatinine ratio (UACR). Triglyceride-glucose index (TyG) was calculated to estimate insulin resistance. The mean age was 61,5 ± 16,4 years. Most patients were female, Afro-Mestizo and over 50 years of age. Pearson's revealed negative correlation of creatinine with HDLc and Apo A-I. There was a correlation of eGFR with HbA1c, TG and HDLc. TyG presented a negative correlation with Apo A-I and HDLc. The highest quartiles of UACR presented the highest TyG and the lowest Apo A-I. In conclusion, Apo A-I indicated an association with insulin resistance and changes in renal function parameters, especially as a factor associated with the onset of albuminuria, with a better predictive potential than the HDLc.

ABSTRACT Introduction: Supplementation with probiotics for patients with chronic kidney disease (CKD) may be associated with decreased systemic inflammation. Objective: To assess the impact of oral supplementation with probiotics for patients with CKD on hemodialysis. Method: This double-blind randomized clinical trial included 70 patients on hemodialysis; 32 were given oral supplementation with probiotics and 38 were in the placebo group. Blood samples were collected at the start of the study and patients were given oral supplementation with probiotics or placebo for three months. The probiotic supplement comprised four strains of encapsulated Gram-positive bacteria: Lactobacillus Plantarum A87, Lactobacillus rhamnosus, Bifidobacterium bifidum A218 and Bifidobacterium longum A101. Patients were given one capsule per day for 3 months. Blood samples were taken throughout the study to check for inflammatory biomarkers. Non-traditional biomarkers Syndecan-1, IFN-y, NGAL, and cystatin C were measured using an ELISA kit, along with biochemical parameters CRP, calcium, phosphorus, potassium, PTH, GPT, hematocrit, hemoglobin, glucose, and urea. Results: Patients given supplementation with probiotics had significant decreases in serum levels of syndecan-1 (239 ± 113 to 184 ± 106 ng/mL, p = 0.005); blood glucose levels also decreased significantly (162 ± 112 to 146 ± 74 mg/dL, p = 0.02). Conclusion: Administration of probiotics to patients with advanced CKD was associated with decreases in syndecan-1 and blood glucose levels, indicating potential improvements in metabolism and decreased systemic inflammation.

Resumo Introdução: A suplementação com probióticos na doença renal crônica (DRC) pode estar associada à redução do processo inflamatório sistêmico. Objetivo: Avaliar a suplementação oral com probióticos em pacientes com DRC em hemodiálise. Método: Ensaio clínico, duplo cego, randomizado com 70 pacientes em hemodiálise, sendo 32 do grupo que recebeu o suplemento de probióticos e 38 do grupo placebo. Inicialmente ocorreu a coleta de sangue e suplementação oral com probióticos ou placebo durante três meses. O suplemento probiótico foi composto pela combinação de 4 cepas de bactérias Gram-positivas encapsuladas: Lactobacillus Plantarum A87, Lactobacillus rhamnosus, Bifidobacterium bifidum A218 e Bifidobacterium longum A101, sendo 1 cápsula do suplemento ao dia, durante 3 meses. Após esse período foram feitas novas coletas de sangue para dosagem dos biomarcadores inflamatórios. Foram analisados os biomarcadores não tradicionais: Syndecan-1, IFN-y, NGAL e cistatina C pelo método ELISA, e os seguintes parâmetros bioquímicos: PCR, cálcio, fósforo, potássio, PTH, TGP, hematócrito, hemoglobina, glicose e ureia. Resultados: Os pacientes que receberam suplemento tiveram diminuição significativa dos níveis séricos de syndecan-1 (de 239 ± 113 para 184 ± 106 ng/mL, p = 0,005). Outro parâmetro que diminuiu significativamente nos pacientes que receberam suplemento foi a glicemia (de 162 ± 112 para 146 ± 74 mg/dL, p = 0,02). Conclusão: O uso de probióticos na DRC avançada esteve associado à redução dos níveis de syndecan-1 e glicemia, sinalizando possível melhora no metabolismo e redução do processo inflamatório sistêmico.

Abstract Objective To analyze the quality of care transition of older adults who were discharged from hospital to home. Methods This is a cross-sectional observational study, conducted with 156 older adults after public hospital admission, located in the municipality of Piracicaba, state of São Paulo. Data were collected in patients’ electronic medical records and by telephone calls with older adults, their relatives and/or caregivers, up to four weeks after hospital discharge. We used a questionnaire with sociodemographic data and the Care Transitions Measure, version validated for Brazil. Results The mean duration of the last hospitalization was 8.27 days, mostly caused (72.44%) by COVID-19 and 75% of older adults had between 1 and 3 comorbidities, with hypertension (57.7%) being the most frequent. The mean CTM-15 score was 68.6. Factor 1, Management preparation, obtained the highest score (70.5), and Factor 4, Care plan, the lowest (59.14). There was a positive correlation between the 4 factors of Care Transitions Measure, also among these factors is the number of drugs used to treat older adults, according to the Anatomical Chemical Therapeutic Classification. Conclusion We evidenced the quality of the transition of care in the hospital close to the value considered satisfactory, with two of the four factors with a score greater than 70; however, there is a need to adopt strategies to improve the discharge process from hospital to home, especially with regard to preferences imported and care plan for older adults.

ABSTRACT Background: The long-term effects of schistosomiasis on the glomerulus may contribute to the development of chronic kidney disease. This study aimed to investigate baseline Schistosoma mansoni-Circulating Anodic Antigen (CAA) levels and their association with kidney biomarkers related to podocyte injury and inflammation in long-term follow-up after praziquantel (PZQ) treatment. Methods: Schistosoma infection was diagnosed by detecting CAA in urine using a quantitative assay based on lateral flow using luminescent up-converting phosphor reporter particles. A cutoff threshold of 0.1 pg/mL CAA was used to diagnose Schistosoma infection (baseline) in a low-prevalence area in Ceará, Northeast, Brazil. Two groups were included: CAA-positive and CAA-negative individuals, both of which received a single dose of PZQ at baseline. Urinary samples from 55 individuals were evaluated before (baseline) and at 1, 2, and 3 years after PZQ treatment. At all time points, kidney biomarkers were quantified in urine and adjusted for urinary creatinine levels. Results: CAA-positive patients had increased baseline albuminuria and proteinuria and showed greater associations between kidney biomarkers. CAA levels correlated only with Vascular Endothelial Growth Factor (VEGF) (podocyte injury) levels. Increasing trends were observed for malondialdehyde (oxidative stress), monocyte chemoattractant protein-1 (inflammation marker), and VEGF. In the follow-up analysis, no relevant differences were observed in kidney biomarkers between the groups and different periods. Conclusions: S. mansoni-infected individuals presented subclinical signs of glomerular damage that may reflect podocyte injury. However, no causal effect on long-term renal function was observed after PZQ treatment.

Abstract Changes in lipoprotein metabolism are among the main causes of hemodynamic impairment in renal function. COVID-19 is an multisystemic inflammatory disease, aggravating this situation. This cross-sectional study investigated the relationship of serum lipoprotein profile with inflammatory parameters and renal function in 95 COVID-19 outpatients in comparison with 173 with flu-like symptoms. Serum samples were collected for the determination of total cholesterol and fractions, apolipoproteins (Apo A-I and Apo B), urea (sUr) and creatinine (sCr). The glomerular filtration rate (eGFR) was calculated. Neutrophil/lymphocyte (NLR) and platelet/lymphocyte (PLR) ratios were calculated as inflammatory parameters derived from the blood tests. COVID-19 patients presented lower high-density lipoprotein cholesterol (HDL-c) (47.90 ± 1.543 vs. 51.40 ± 0.992) and higher PLR (190.9 ± 9.410 vs. 137.6 ± 5.534) and NLR (3.40 ± 0.22 vs. 2.80 ± 0.15). Both NLR and PLR correlated with each other (r = 0.639). Furthermore, the Apo B/Apo A-I ratio was correlated with PLR (r = 0.5818) and eGFR (r = -0.2630). COVID-19 patients classified as at high risk of developing acute myocardial infarction based on the Apo B/ Apo A-I ratio had higher values for sUr/sCr. Thus, serum apolipoproteins, PLR, and NLR could be related to renal dysfunction in COVID-19.

Resumo A lesão renal aguda (LRA) é comum na Unidade de Terapia Intensiva Neonatal (nUTI) e a sepse é uma de suas principais causas, especialmente em prematuros. Apresenta altas taxas de mortalidade e sua detecção precoce é o primeiro passo para a prevenção dessa condição, pois permite o tratamento adequado e melhora o desfecho, diminui o tempo de internação, os custos não médicos e a morbimortalidade. Destaca-se ainda que a LRA pode evoluir para doença renal crônica (DRC), havendo a necessidade de diálise, com maior risco de desenvolver doenças cardiovasculares. Este artigo de revisão tem como objetivo discutir a LRA em recém-nascidos (RNs) prematuros com sepse, abordando biomarcadores utilizados na rotina laboratorial e principalmente a utilização de biomarcadores não tradicionais para identificação precoce de LRA.

Abstract Acute kidney injury (AKI) is a common finding in Neotatal Intensive Care Units (NICU). Sepsis is one the main causes of AKI in preterm newborns. AKI has been associated with significant death rates. Early detection of the condition is the first step to improving prevention, treatment, and outcomes, while decreasing length of hospitalization, care costs, and morbimortality. AKI may progress to chronic kidney disease (CKD), a condition linked with dialysis and greater risk of cardiovascular disease. This review article aims to discuss cases of AKI in preterm newborns with sepsis, the use of biomarkers in lab workup, and the use of non-conventional biomarkers for the early identification of AKI.

ABSTRACT. The management of weeds in melon is hindered by the slow initial growth of the crop, favouring weed infestation and reducing production. During the years 2016 and 2017, weed interference periods were evaluated in two melon hybrids, yellow and frog skin, to determine the time of weed control in the crop. Four-parameter logistic regression was used to determine the critical weed control period (CPWC). The weed species with the highest occurrences in 2016 were Merremia aegyptia, Senna obtusifolia, and Urochloa plantaginea. In 2017, there was a predominance of M. aegyptia, indicating the possibility of successive cultivation, favouring the predominance of species with growth habits similar to melons. The increase in the period of living with weeds reduced the productivity and quality of melon fruits. Coexistence with weeds throughout the cycle reduced productivity by about 50%. The CPWC was 15 to 58 and 10 to 45 for frog skin and 12 to 52 and 4 to 50 days for yellow melon in 2016 and 2017, respectively, considering a productivity loss of 5%. These results underscore the importance of adopting strategies that allow melons to grow free from the presence of weeds, especially before they are fully established in the growing area.

Abstract INTRODUCTION: This study estimated the seroprevalence and risk factors of Chagas disease (CD) in a population of the Quixeré municipality, Ceará. METHODS: We conducted serological methods to detect the Trypanosoma cruzi infection. The other variables were evaluated by a standardized questionnaire. RESULTS: The estimated prevalence of CD was 3.7%. Male sex, age >40 years, being farmers, low education level, origin from rural areas, and being born in Quixeré were significantly associated with infection. CONCLUSION: CD persists in this rural population of Northeast Brazil. Poverty, low education, and limited information regarding CD are critical issues that need to be addressed.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Resumo COVID-19 é uma pandemia associada a manifestações clínicas sistêmicas. Neste estudo, apresenta-se revisão narrativa acerca do envolvimento renal na COVID-19. Envolvimento renal parece ser relacionado a efeitos citopáticos diretos, mecanismos imunológicos, efeitos indiretos de outros mediadores no tecido renal, além de disfunção e lesão de outros órgãos. A evolução da COVID-19 pode ser complicada por lesão renal aguda (LRA) em percentual significativo dos pacientes, e a disfunção renal parece ser associada a pior prognóstico. Pacientes com doença renal crônica (DRC) parecem ser mais suscetíveis a formas severas da COVID-19. Pacientes em terapia de substituição renal (TSR) contínua também constituem população vulnerável em razão de idade avançada, comorbidades subjacentes, resposta imune disfuncional e aglomeração em unidades de diálise, com necessidade de visitas frequentes aos serviços de saúde. Pacientes transplantados renais podem estar em alto risco dadas imunossupressão a longo prazo e comorbidades; assim, o manejo da imunossupressão é mandatório. Finalmente, TSR pode ser necessária durante a COVID-19, e diferentes modalidades são discutidas conforme manifestações clínicas e aspectos laboratoriais. Assim, COVID-19 parece acometer os rins por diferentes mecanismos, os quais contribuem para o desenvolvimento de LRA e aumento da severidade da doença. Ainda, pacientes com DRC e transplantados renais apresentam elevado risco para desenvolvimento de COVID-19 e de mortalidade.

Abstract COVID-19 is a pandemic associated with systemic clinical manifestations. In this study, we aimed to present a narrative review on kidney involvement in COVID-19. Kidney involvement could be derived from direct cytopathic effects, immunological mechanisms, indirect effects on renal tissue through other mediators, and dysfunction or injury of other organs. The evolution of COVID-19 may be complicated with acute kidney injury (AKI) in a significant percentage of patients, and renal dysfunction seems to be associated with worse prognosis. Patients with chronic kidney disease (CKD) seem to be more susceptible to the severe forms of COVID-19. Patients with renal replacement therapy (RRT) are also a vulnerable population as consequence of their advanced age, underlying comorbidities, impaired immune response, and clustering in hemodialysis centers, with requirements for frequent contact with healthcare services. Kidney transplant patients may be at high-risk due to long-term immunosuppression and comorbidities, hence, managing immunosuppression is imperative. Lastly, renal replacement therapy may be required during COVID-19, and different modalities are discussed based on clinical findings and laboratorial aspects. Therefore, COVID-19 seems to affect kidney by different mechanisms, which contributes for AKI development and increases the severity of the disease. Also, patients with CKD and kidney transplant recipients are at higher risk for COVID-19 and mortality.

Abstract: En | Text: En | PDF: En

Abstract Ischemia-reperfusion (I/R) plays an important role in the process of acute kidney injury (AKI) due to the generation of reactive oxygen species (ROS). Substances of natural origin have been studied in the prevention of oxidative damage related to I/R. Quercetin is a flavonoid with antioxidant potential and modulate enzymes, such the inhibition of the Rennin-Angiotensin System (RAS). The aim of this study is to evaluate the nephroprotective effect of quercetin against the I/R and analyze the inhibition of RAS. Rhesus monkey Kidney Epithelial Cells (LLC-MK2 line) were submitted to an in vitro ischemia/reperfusion model. After the reperfusion cells were treated with quercetin, the cell viability was accessed by the MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) assay. Tubular cell damage was assessed by the Kidney Injury Molecule-1 (KIM-1) measurement. Oxidative stress was evaluated through Thiobarbituric Acid Reactive Substances (TBARS) and reduced glutathione (GSH). The evaluation of cell death and the mitochondrial depolarization were analyzed by flow cytometry. Quercetin prevents cell death reducing oxidative stress and preventing mitochondrial membrane depolarization. Molecular docking showed that quercetin prevents cell damage better than losartan and lisinopril, inhibitors of RAS. Quercetin has a potential to interact with type 1 angiotensin II receptor (AT1) with greater affinity through the formation of five hydrogen bonds of strong intensity.
