RESUMO
OBJECTIVE: The aim of this cross-sectional study was to evaluate the relationship between eating patterns and diabetic kidney disease in patients with type 2 diabetes. METHODS: Outpatients underwent clinical and nutritional evaluation. Dietary information was obtained through a validated quantitative food frequency questionnaire, and eating patterns were identified by cluster analysis. Diabetic kidney disease was defined as an estimated glomerular filtration rate <60 mL/min/1.73 m2 and/or persistently elevated urinary albumin concentration (albuminuria ≥ 14 mg/L). Procedures involving patients were approved by the Hospital's Ethics Committee. Patients with type 2 diabetes treated at university hospital and tertiary referral center, southern Brazil. RESULTS: A total of 329 patients were evaluated: mean age 62 ± 10 years, body mass index 30.9 ± 4.2 kg/m2, glycated hemoglobin 8.7% ± 2.0, and 10 (5 to 19) years of diabetes duration. Four eating patterns were identified based on cluster analysis: healthy= dairy products, fruits, and vegetables; snacks= dairy products, whole breads, vegetables, and low-calorie products; processed foods= refined carbohydrates and processed meat, and red meat= red meat. Poisson regression models confirmed that snack eaters (PR = 1.48, 95% CI 1.10, 1.99; P = .010) and red meat eaters (PR = 1.93, 95% CI 1.29, 2.89; P = .001) were associated with diabetic kidney disease. CONCLUSION: In this sample of outpatients with type 2 diabetes, the patterns of snacks and red meat were associated with diabetic kidney disease as compared to a healthy pattern.

Kidney disease in diabetes mellitus is usually explained by diabetic kidney disease, but other superimposed etiologies occur frequently. The distinction between diabetic kidney disease and non-diabetic kidney disease can only be made by performing kidney biopsy. Our objective was to evaluate the association of diabetic kidney disease, non-diabetic kidney disease, or both with renal replacement therapy initiation. This is a retrospective cohort that included patients with type 2 diabetes mellitus for whom a kidney biopsy was indicated. Subjects were followed-up for 5 years, until renal replacement therapy initiation or were lost to follow up. One hundred and forty-one patients were included, 53 (39%) had diabetic kidney disease, 13 (9%) had non-diabetic kidney disease and 75 (54%) had both. Ninety-four percent of the cohort initiated renal replacement therapy during the 5-year follow-up. Higher degree of fibrosis was associated with a trend towards higher risk of requiring renal replacement therapy. In addition, the combined diabetic kidney disease + non-diabetic kidney disease group was associated with higher need of renal replacement therapy initiation when compared to the diabetic kidney disease group.

Background: In a context where the prevalence of Diabetes Mellitus and Hypertension has increased significantly in recent years, kidney diseases become important for the potential demand for specialized health care and resources required. Objective: To analyze the geographical distribution of Diabetic Nephropathy (DN) and Renal Insufficiency (RI) based on the medical consultations given in first-level units of IMSS during 2019, to identify the medical units with the highest burden of care. Material and methods: Ecological-exploratory study in which indicators were estimated for every thousand persons in relation to medical consultations given by ND and RI according to service time, first-level medical unit (UMF) and representation to analyze the magnitude and geographic distribution at the national level. Results: 45% of medical consultations were by ND and 52.4% by RI. The highest burden per DN was registered in UMF No. 50 Cd. Juarez (Chihuahua) and No. 49 Gabino Barreda (Veracruz Sur), with 1.7 first-time medical consultations and 148.3 subsequent medical consultations per 1,000 persons, respectively. While in UMF No. 40 Manlio Fabio Altamirano and No. 25 Cotaxtla, in Veracruz Norte, the highest burden was for RI, with 4.9 first-time medical consultations and 134.2 subsequent medical consultations per 1000 persons, respectively. Conclusions: The results could contribute to strengthening of medical units where it is necessary and the efficient allocation of resources available to meet the demand for health services of ND and RI in IMSS.

Diabetic kidney disease (DKD) is the leading cause of chronic kidney disease (CKD) worldwide, contributing to a great burden across a variety of patient-reported and clinical outcomes. New interventions for DKD management have been established in recent years, unleashing a novel paradigm, in which kidney-dedicated trials yield informative and robust data to guide optimal clinical management. After unprecedented results from groundbreaking randomized controlled trials were released, a new scenario of evidence-based recommendations has evolved for the management of diabetic patients with CKD. The current guidelines place great emphasis on multidimensional and interdisciplinary approaches, but the challenges of implementation are just starting and will be pivotal to optimize clinical results and to understand the new threshold for residual risk in DKD. We thereby provide an updated review on recent advances in DKD management based on new guideline recommendations, summarizing recent evidence while projecting the landscape for innovative ongoing initiatives in the field. Specifically, we review current insights on the natural history, epidemiology, pathogenesis, and therapeutics of DKD, mapping the new scientific information into the recently released Kidney Disease - Improving Global Outcomes Guidelines translating results from major novel randomized controlled trials to the clinical practice. Additionally, we approach the landscape of new therapeutics in the field, summarizing ongoing phase IIb and III trials focused on DKD. Finally, reflecting on the past and looking into the future, we highlight unmet needs in the current DKD management based on real-world evidence and offer a nephrologist's perspective into the challenge of fostering continuous improvement on clinical and patient-reported outcomes for individuals living with DKD.

Background: The effect of glycemic control on diabetic kidney disease (DKD) is well known. Recent evidence has suggested that Vitamin D (VD) may have a nephroprotective effect in diabetes, but the relationship between VD, glycemic control, and albuminuria has yet to be clarified. Objective: Evaluate the relationship between 25-hydroxy-vitamin D [25(OH)D], HbA1c, and albuminuria in Diabetes Mellitus (DM). Patients and Methods: Cross-sectional study with 1576 individuals with DM who had 25(OH)D, HbA1c, and albuminuria levels measured. Patients with abnormal creatinine levels were excluded, in order to avoid interference on VD levels by impaired kidney function. Results: Patients with HbA1c ≥7% had lower 25(OH)D when compared to patients with HbA1c <7% (29.7 ± 10.2 vs 28.1 ± 9.9 ng/ml, p = 0.003) and 25(OH)D levels seems to predict 1.5% of HbA1c behavior. The 25(OH)D concentrations in patients with normoalbuminuria were higher than the levels observed in those with micro or macroalbuminuria (29.8 ± 9.0 vs 26.8 ± 8.6 and 25.1 ± 7.6, respectively, p = 0.001), patients who had 25(OH)D <20 ng/ml and 25(OH)D <30 ng/ml were at a higher risk of presenting albuminuria [OR = 2.8 (95% CI = 1.6 - 4.9), p<0.001, and OR = 2.1 (95% CI = 1.3 - 4.6), p<0.001, respectively]. In our regression model, albuminuria was influenced by HbA1c (r² = 0.076, p<0.00001) and 25(OH)D (r² = 0.018, p = 0.002) independently. Conclusion: Our study found an association between vitamin D levels, HbA1c and DKD. Additionally, our data suggest that the association between urinary albumin excretion and vitamin D levels is independent of glycemic control in patients with diabetes. Even though our patients presented normal creatinine levels, it is necessary further prospective studies to confirm if this association precedes or not the loss of renal function.

La diabetes mellitus tipo 2 (DM2), habitualmente asociada a adultos en edad media y adulto mayor, ha presentado un aumento en su incidencia en pacientes menores de 40 años, lo que se conoce como DM2 de inicio en paciente joven. Varios estudios sugieren que este tipo de diabetes presenta no sólo un deterioro más rápido de las células beta-pancreáticas en comparación con la DM2 de inicio más tardío, sino que también un mayor riesgo de complicaciones que pacientes con DM Tipo1, lo que sugiere una variable independiente de los años de exposición a la enfermedad y por tanto, un fenotipo más agresivo. Por otra parte, hay evidencia que afirma que existen grupos poblacionales en mayor riesgo de desarrollar esta patología, particularmente ciertas etnias. En el presente trabajo se exponen los principales hallazgos de una reciente revisión del tema y se los compara con los datos nacionales disponibles. Dada la alta prevalencia de DM2 en la población chilena y la escasa cantidad de estudios epidemiológicos de calidad que permitan conocer nuestro panorama con mayor precisión, es que se destaca la importancia de estos últimos para poder tomar medidas de salud pública adecuadas.
Type 2 diabetes mellitus type 2 (T2DM), commonly associated with the middle to old aged adults group, has shown an increase in incidence in patients younger than 40 years old, which is known as young-onset type 2 diabetes mellitus. Several studies suggest that this type of diabetes not only exhibits a faster deterioration of the beta-pancreatic cells in comparison with type 1 diabetes mellitus patients, but also a greater risk of complications not regarding the time of exposure to the disease, therefore a more aggressive phenotype. Otherwise, there is evidence which asserts that some population groups are in mayor risk of developing this disease, especially certain ethnics. In this work it is exposed the main findings of a recent review of the subject and it is contrasted with available national data. Given the high prevalence of T2DM in the chilean population and the little amount of epidemiological high-quality studies that allows us to know our outlook with greater precision, it is highlighted the need for them in order to make adequate public health decisions.

AIMS: To evaluate diagnosis, prevalence and associated factors of CKD in Brazilian patients with type 1 diabetes. METHODS: This cross-sectional, multicenter study was conducted in 14 public clinics in 10 Brazilian cities. From 1760 patients, 1736 were included (98.6%): 977 females (56.3%), 932 (54%) Caucasians, aged 29.9 ± 11.9 years, age at diagnosis 14.7 ± 8.9 years, diabetes duration 15.5 ± 9.3 years and 12.2 ± 3.8 years of school attendance. CKD was determined by using estimated glomerular filtration rate and by the presence of albuminuria in two out of three morning urine samples. RESULTS: The prevalence of CKD was 33.7%. Overall, 28.1% of the patients could not be classified due to insufficient number of urine samples for albuminuria determination. Multivariable analysis showed that female gender, diabetes duration, high levels of HbA1c and uric acid, use of renin-angiotensin system inhibitors, retinopathy, high systolic blood pressure, and economic status (medium, low and very low) were associated with CKD. CONCLUSIONS: Although a high prevalence of CKD, associated comorbidities and retinopathy was observed in our study, a large number of patients are still undiagnosed, making CKD a challenge in routine clinical practice in admixed populations with T1D in a developing country like Brazil.

OBJECTIVE: To evaluate the prevalence of nondiabetic renal diseases (NDRDs) in renal biopsies of patients with diabetes mellitus (DM) in the University Hospital of Ribeirão Preto, São Paulo. Research Design and Methods. We conducted a retrospective study including kidney biopsies performed in diabetic patients between 1987 and 2013. We evaluated 79 biopsies during this period. The primary variable was the prevalence of NDRD in patients with DM. The secondary variables were the presence of systemic arterial hypertension (SAH), hematuria, time since diagnosis of DM, serum creatinine, and proteinuria levels. The cases were divided into the following groups: isolated diabetic nephropathy (DN-group I), isolated nondiabetic renal diseases (NDRD-group II), associated NDRD/DN (group III), and associated NDRD+NDRD/DN (group IV). RESULTS: Most of the patients (58.22%) presented only alterations arising from DN. NDRDs were present in 41.77% of the patients. Membranous glomerulonephritis (30.3%) and IgA nephropathy (24.24%) were the most prevalent NDRDs. We found no differences between female and male patients with NDRD when assessing the secondary variables. A time since diagnosis of five years or less revealed a statistical difference (p = 0.0005) in the comparison between the isolated DN (group I) and the NDRD+NDRD/DN (group IV). The other secondary variables were not significant in the comparison of the groups. CONCLUSIONS: We concluded that the prevalence of NDRD is 41.77%. Membranous glomerulonephritis was the most prevalent NDRD in our study. We also conclude that the probability of the presence of NDRD with or without concomitant DN is greater for patients who had biopsies with a time since diagnosis of five years or less. A time since diagnosis of ten years or more does not allow the exclusion of the presence of NDRD.

Chronic renal disease patients under chronic dialysis (CRDD) have a multifactorial immunological deterioration with an increased risk of Candida infections. Incidence of Candida infections is increasing. Choice of suitable antifungal agents is limited due to the resistance of some species to several antifungals. Aim of the present study was to identify the distribution and antifungal susceptibility patterns of oral isolated Candida species from infected and colonized patients, as well as to investigate the risk factors for oral infection in patients on dialysis. Cross-sectional study, approved by the institutional bioethics committees was performed in CRDD patients. Demographic, clinic data, and oral mucosa samples were obtained. Infection diagnosis was established clinically and confirmed with exfoliative cytology, each sample was plated on CHROMagar Candida and incubated at 36°C for 2 days. Yeast species were identified by carbohydrate assimilation ID 32C AUX system and the apiweb database. For the antifungal susceptibility test, the M44 A-3 method (CLSI) using fluconazole (FCZ), miconazole (MCZ), nystatin (NYS), and voriconazole (VCZ). Study included 119 participants, the main cause of CRD was nephropathy due to DM2 (58%), and three-fourths of the patients were under hemodialysis. Candida prevalence was 56.3% of 67 colonized or infected patients, 88 isolates were obtained. Principal identified species were C. albicans (51.1%), C. glabrata (25%), and C. tropicalis (14.8%). C. glabrata showed a reduced response to FCZ in 50% of isolates and C. albicans had a reduced response in 16% of the isolates. Antifungal agent with the least efficacious response or with the lowest susceptibility in the isolates of these patients was MCZ, followed by VCZ and FCZ, whereas NYS induced the best antifungal response.
