Abstract Objective To identify the prevalence of functional health literacy and analyze the association between functional health literacy levels and clinical and sociodemographic variables in non-dialysis chronic kidney disease patients. Methods This is a cross-sectional study carried out with 167 chronic kidney disease patients being monitored at the nephrology outpatient clinic of a large city in the state of Minas Gerais, Brazil. For the interviews, a sociodemographic and clinical questionnaire and the Brazilian version of the Short Assessment of Health Literacy for Portuguese Speaking Adults (SAHLPA-18) were used to measure functional health literacy. Descriptive statistics were performed for sociodemographic and clinical variables, and correlation tests and linear regression models for association with functional health literacy. Results Most participants were older adults with a median age of 68 years, 33.3% (56 patients) were in stage 3B of chronic kidney disease and 53.9% (90 patients) had inadequate functional health literacy. There was no association between functional health literacy levels and clinical variables. The majority reported not using the internet and the more advanced stage of chronic kidney disease had lower literacy scores. Worse functional health literacy scores were also identified in those with lower income. Conclusion Most participants had inadequate functional health literacy. Clinical variables were not predictors of literacy scores. However, lower health literacy scores were identified in those with more advanced stage kidney disease, lower income and less internet use.

Abstract Introduction: Screening patients with diabetes mellitus (DM) for chronic kidney disease (CKD) enables early diagnosis and helps to establish adequate treatment and avoid possible damages to health associated with disease progression. This study aimed to verify whether screening for CKD has been properly conducted in populations with diabetes mellitus seen at primary care clinics. Methods: This descriptive study included 265 individuals with DM seen at Basic Healthcare Clinics in Divinópolis, MG, Brazil. Clinical and laboratory data were collected from the Integrated Health System. Frequency of testing and kidney function evaluations performed within the last 12 months were calculated along with the proportion of patients with increased urinary albumin excretion (UAE) and decreased glomerular filtration rate (GFR) to determine the proportion of patient with kidney involvement. Results: We found that 41.2% of the patients had kidney involvement and that 61.2% of the individuals with kidney involvement were on nephroprotective medication. Of the 21.9% tested for isolated albuminuria, 46.5% had increased UAE. The albumin-to-creatinine ratio (ACR) was measured in 12.1% of the patients, with 43.8% having an increased ACR. We found that 89.0% of the patients had their serum creatinine levels measured, and that 33.1% had a decreased GFR. Conclusion: CKD screening was more frequently performed via the GFR than UAE, a parameter analyzed only in a small proportion of patients. Therefore, CKD screening for patients with diabetes is not being performed properly in primary care.
Resumo Introdução: O rastreio da doença renal crônica (DRC) em pacientes com diabetes (DM) possibilita o diagnóstico precoce e ajuda a estabelecer um tratamento adequado, evitando possíveis danos à saúde pela progressão da doença. O objetivo deste trabalho foi verificar se o rastreio da DRC está sendo feito de maneira adequada entre diabéticos acompanhados na atenção primária à saúde. Métodos: Estudo descritivo com 265 pacientes com DM atendidos nas Unidades Básicas de Saúde de Divinópolis, MG. A coleta de dados clínicos e laboratoriais foi realizada por meio de consulta ao Sistema Integrado de Saúde. Foram calculadas a frequência de realização dos exames de avaliação da função renal nos últimos 12 meses e a frequência de pacientes com excreção urinária de albumina (EUA) aumentada e a taxa de filtração glomerular (TFG) reduzida, e assim determinada a frequência de pacientes com comprometimento renal. Resultados: Foi observado que 41,2% dos pacientes têm comprometimento renal; dentre esses, 61,2% utilizam algum medicamento nefroprotetor. Apenas 21,9% realizaram o exame de albuminúria isolada, dos quais 46,5% apresentaram albuminúria aumentada. O exame de relação albumina/creatinina (RAC) foi realizado por 12,1% dos pacientes, dos quais 43,8% apresentaram RAC aumentada. Foi observado que 89,0% dos pacientes realizaram o exame de creatinina sérica, dos quais 33,1% apresentaram TFG reduzida. Conclusão: Foi observado maior índice de rastreio da DRC por meio da TFG em relação ao rastreio por meio da EUA, o qual foi realizado por pequeno número de pacientes. Portanto, o rastreio da DRC não está sendo realizado adequadamente na atenção básica ao diabético.
RESUMO
Introduction: Post-streptococcal glomerulonephritis (PSGN) has a good prognosis in children, but few studies have evaluated the long-term renal outcomes in adults with PSGN. Methods: In a follow-up study, 47 predominantly adult patients with PSGN due to group C Streptococcus zooepidemicus were reassessed 20 years after an outbreak in Nova Serrana, Brazil. We evaluated clinical characteristics, renal outcomes, and the trajectory of the estimated glomerular filtration rate (eGFR) by the creatinine-based chronic kidney disease-epidemiology collaboration equation from 5 follow-up assessments. Logistic regression and mixed-effects regression were used in the analysis. Results: After 20 years, the participants' mean age was 56.6±15.1 years. Thirty-four (72%) patients had hypertension, 21 (44.7%) had eGFR <60 ml/min per 1.73 m2, 8 of 43 (18.6%) had urine protein-to-creatinine ratio >150 mg/g, and 25 (53%) had CKD (low eGFR and/or increased proteinuria). Increasing age was associated with CKD (odds ratio: 1.07; 95% confidence interval [CI]: 1.02-1.13; P = 0.011) in multivariate analysis. The mean eGFR decline in the last 11 years of follow-up was -3.2 ml/min per 1.73 m2 per year (95% CI: -3.7 to -2.7). Older age at baseline (coefficient -1.05 ml/min per 1.73 m2 per year; 95% CI -1.28 to -0.81; P < 0.001), and hypertension 5 years after the outbreak (coefficient -7.78 ml/min/1.73 m2; 95% CI -14.67 to -0.78; P = 0.027) were associated with lower eGFR during the whole study period. Conclusion: There was a marked worsening of renal function and a high prevalence of CKD and hypertension after 20 years of PSGN outbreak. Long-term follow-up is warranted after PSGN, especially among older patients.
RESUMO
Introdução: o objetivo foi avaliar a prevalência do distúrbio mineral e ósseo em pacientes com doença renal crônica e a associação entre Taxa de Filtração Glomerular estimada (TFGe) e os indicadores do distúrbio mineral e ósseo (DMO) (cálcio, fósforo e PTH) em pacientes renais crônicos não dialíticos. Materiais e Métodos: estudo seccional da linha de base de uma coorte de dois anos, com adultos e idosos renais crônicos em tratamento conservador. Para identificação do DMO utilizamos os seguintes valores séricos: PTH (> 150 pg/mL) e/ou hipocalcemia (Ca < 8,8mg/dl) e/ou hiperfosfatemia (P > 4,6 mg/dl). Na análise estatística utilizou-se: regressão de Poisson; T de Student, Mann Whitney e correlações de Pearson e Spearman. Nível de significância foi de 5%. Resultados: prevalência de DMO de 54,6% (n=41) (IC 95%: 43,45 - 65,43). A maior prevalência de DMO foi em pessoas do sexo feminino, alfabetizadas, idosas, não etilistas, não tabagistas, sedentárias e de cor de pele branca, porém, sem diferença estatística entre os grupos com e sem DMO. As correlações entre P e PTH com TFGe foram significativas, inversas, de força moderada (p= <0,005 e p = 0,003; coeficientes de correlação = - 0,312 e - 0,379 respectivamente). Discussão:os achados desse estudo mostraram que existe uma lacuna no acompanhamento do DMO-DRC pela atenção primária e a prática clínica deve ser revista. Conclusão:identificou-se prevalência robusta de DMO nos estágios precoces da DRC, além de correlações significativas entre o aumento dos níveis de fósforo e PTH e piora das funções renais.
Introduction: mineral and bone disorder (BMD) is a serious complication of chronic kidney disease (CKD) that increases risks for death from cardiovascular causes and impairs quality of life of affected patients. Objetive: to evaluate the prevalence of BMD in patients with CKD and the association between estimated Glomerular Filtration Rate (eGFR) and BMD indicators (calcium, phosphorus and PTH) in non-dialysis patients. Materials and Methods:sectional study of a two-year cohort of chronic renal adults and elderly patients on conservative treatment. BMD was identified by serum values of: PTH (> 150 pg/mL) and/or hypocalcemia (Ca < 8.8mg/dl) and/or hyperphosphatemia (P > 4.6 mg/dl). The statistical analysis used: Poisson regression; Student's T, Mann Whitney and Pearson and Spearman correlations with 5% significance level. Results:BMD prevalence was 54.6% (n=41) (95% CI: 43.45 - 65.43), more frequent in women, literate, elderly, non-drinkers, non-smokers, sedentary and white skin color. Correlations between P and PTH with GFRe were significant, inverse, moderate strength (p= <0.005 and p = 0.003; correlation coefficients = - 0.312 and - 0.379 respectively). Discussion: the findings of this study highlighted gaps in the monitoring of BMD-DRC by primary care, requiring a review of clinical practices. Conclusion: robust prevalence of BMD in the early stages of CKD was identified, in addition to correlations between increased phosphorus and PTH levels and worsening kidney function.
Introducciòn: el trastorno mineral y óseo (TMO) es una complicación grave de la enfermedad renal crónica (ERC) que aumenta el riesgo de muerte por causas cardiovasculares y deteriora la calidad de vida de los pacientes afectados. Objetivo: evaluar la prevalencia de la DMO en pacientes con RDC y la asociación entre la tasa de filtración glomerular estimada (TFGe) y los indicadores de DMO (calcio, fósforo y PTH) en pacientes no dialíticos. Materiales y Métodos: estudio seccional de una cohorte de dos años de pacientes renales crónicos adultos y ancianos en tratamiento conservador. La DMO se identificó por los valores séricos de: PTH (> 150 pg/mL) y/o hipocalcemia (Ca < 8,8mg/dl) y/o hiperfosfatemia (P > 4,6 mg/dl). El análisis estadístico utilizado: regresión de Poisson; T de Student, Mann Whitney y correlaciones de Pearson y Spearman con un nivel de significación del 5%. Resultados: la prevalencia de DMO fue del 54,6% (n=41) (IC 95%: 43,45 - 65,43), más frecuente en mujeres, alfabetizadas, de edad avanzada, no bebedoras, no fumadoras, sedentarias y de color de piel blanca. Las correlaciones entre el P y la PTH con el GFRe fueron significativas, inversas, de fuerza moderada (p= <0,005 y p = 0,003; coeficientes de correlación = - 0,312 y - 0,379 respectivamente). Discusión: los resultados de este estudio evidencian lagunas en el seguimiento de la DMO-DRC por parte de la atención primaria, lo que requiere una revisión de las prácticas clínicas. Conclusión: se identificó una fuerte prevalencia de la DMO en las primeras fases de la ERC, además de correlaciones entre el aumento de los niveles de fósforo y PTH y el empeoramiento de la función renal.

Abstract Introduction: Studies have shown that the renin angiotensin aldosterone system (RAAS) and inflammation are related to kidney injury progression. The aim of this study was to evaluate RAAS molecules and chemokine (C-C motif) ligand 2 (CCL2) in 82 patients with chronic kidney disease (CKD). Methods: Patients were divided into two groups: patients diagnosed with CKD and patients without a CKD diagnosis. Glomerular filtration rate (GFR) and albumin/creatinine ratio (ACR) were determined, as well as plasma levels of angiotensin-(1-7) [Ang-(1-7)], angiotensin-converting enzyme (ACE)1, ACE2, and plasma and urinary levels of CCL2. Results: CCL2 plasma levels were significantly higher in patients with CKD compared to the control group. Patients with lower GFR had higher plasma levels of ACE2 and CCL2 and lower ratio ACE1/ACE2. Patients with higher ACR values had higher ACE1 plasma levels. Conclusion: Patients with CKD showed greater activity of both RAAS axes, the classic and alternative, and higher plasma levels of CCL2. Therefore, plasma levels of RAAS molecules and CCL2 seem to be promising prognostic markers and even therapeutic targets for CKD.
Resumo Introdução: Estudos têm mostrado que o sistema renina angiotensina aldosterona (SRAA) e a inflamação estão relacionados à progressão da lesão renal. O objetivo deste estudo foi avaliar moléculas do SRAA e o Ligante 2 de Quimiocina com Motivo C-C (CCL2) em 82 pacientes com doença renal crônica (DRC). Métodos: Os pacientes foram divididos em dois grupos: pacientes diagnosticados com DRC e pacientes sem diagnóstico de DRC. Foram determinadas a taxa de filtração glomerular (TFG) e a relação albumina/creatinina (RAC), assim como os níveis plasmáticos de angiotensina-(1-7) [Ang-(1-7)], enzima conversora de angiotensina (ECA)1, ECA2 e níveis plasmáticos e urinários de CCL2. Resultados: Os níveis plasmáticos de CCL2 foram significativamente mais altos em pacientes com DRC em comparação com o grupo controle. Pacientes com TFG mais baixa apresentaram níveis plasmáticos mais elevados de ECA2 e CCL2 e menor relação ECA1/ECA2. Pacientes com valores de RAC mais altos apresentaram níveis plasmáticos de ECA1 mais elevados. Conclusão: Pacientes com DRC mostraram maior atividade de ambos os eixos do SRAA, o clássico e o alternativo, e níveis plasmáticos mais altos de CCL2. Portanto, os níveis plasmáticos de moléculas do SRAA e CCL2 parecem ser marcadores prognósticos promissores e até mesmo alvos terapêuticos para a DRC.

Abstract Evidence on factors associated with the progression of chronic kidney disease (CKD) is still under construction. The present study aimed to evaluate sociodemographic, clinical, and drug use factors associated with the progression of CKD. A retrospective cohort study was conducted with 193 patients with CKD stages 3A to 5- non-dialysis followed for three years in a Brazilian city. The outcome was the evolution to renal replacement therapy (RRT) or death. A total of 52.3 % (n = 101) were men and 83.4 % (n = 161) elderly. The median age was 72.0 years, and 22.3 % (n = 44) progressed to RRT or death, and the three-year mortality rate was 20.2 %. Participants exposed to angiotensin converting enzyme inhibitors or angiotensin II receptor blockers had a lower risk of progressing to the outcome (hazard ratio (HR) 0.25; p = 0.003) and higher survival (p = 0.022) when compared to those not exposed to these drugs. Age (HR 1.06;) and use of omeprazole (HR 6.25; CI; p <0.01) and hydrochlorothiazide (HR 2.80; p = 0.028) increased the risks of RRT or death. The results highlight the importance of rational management of pharmacotherapy for patients with CKD

Abstract Introduction: Progressive structural changes in the peritoneal membrane occur over the course of treatment in peritoneal dialysis (PD), resulting in an increase in cytokines such as CCL2 and structural changes in peritoneal membrane triggering an increase in CA-125 in dialysate, which reflects a probable local inflammatory process, with possible loss of mesothelial cells. Thus, the current study aimed to evaluate the association between plasma and CCL2 and CA-125 dialysate levels in patients undergoing PD. Methods: Cross-sectional study was conducted with 41 patients undergoing PD. The assessments of CA-125 and CCL2 levels were performed using a capture ELISA. Correlations were estimated using Spearman's correlation and the investigation of the association between the explanatory variables (CCL2) and response variable (CA-125) was done for crude ratio of arithmetic means and adjusted utilizing generalized linear models. Results: A moderate positive correlation was observed between the levels of CA-125 and CCL2 in the dialysate (rho = 0.696). A statistically significant association was found between the levels in the CCL2 and CA-125 dialysate (RoM=1.31; CI = 1.20-1.43), which remained after adjustment for age (RoM = 1.31; CI=1.19-1.44) and for time in months of PD (RoM=1.34, CI=1.22-1.48). Conclusion: The association of CA-125 levels with CCL2 in the dialysate may indicate that the local inflammatory process leads to temporary or definitive changes in peritoneal membrane. A better understanding of this pathogenesis could contribute to the discovery of new inflammatory biomarkers.
Resumo Introdução: Alterações estruturais progressivas na membrana peritoneal ocorrem no decorrer do tratamento em diálise peritoneal (DP), resultando em um aumento de citocinas como CCL2 e alterações estruturais na membrana peritoneal desencadeando um aumento de CA-125 no dialisato, o que reflete um provável processo inflamatório local, com possível perda de células mesoteliais. Assim, o presente estudo teve como objetivo avaliar a associação entre CCL2 e CA-125 no plasma e no dialisato de pacientes submetidos à DP. Métodos: Foi realizado um estudo transversal com 41 pacientes submetidos à DP. As avaliações dos níveis de CA-125 e CCL2 foram realizadas utilizando ELISA de captura. As correlações foram estimadas usando a correlação de Spearman, e a investigação da associação entre as variáveis explicativas (CCL2) e a variável resposta (CA-125) foi feita pela razão bruta das médias aritméticas e ajustada utilizando modelos lineares generalizados. Resultados: Foi observada uma correlação positiva moderada entre os níveis de CA-125 e CCL2 no dialisato (rho = 0,696). Foi encontrada uma associação estatisticamente significativa entre os níveis no dialisato de CCL2 e CA-125 (RoM=1,31; IC = 1,20-1,43), que permaneceu após ajuste por idade (RoM = 1,31; IC=1,19-1,44) e pelo tempo de DP em meses (RoM=1,34, IC=1,22-1,48). Conclusão: A associação dos níveis de CA-125 com CCL2 no dialisato pode indicar que o processo inflamatório local leva a alterações temporárias ou definitivas na membrana peritoneal. Uma melhor compreensão desta patogênese pode contribuir para a descoberta de novos biomarcadores inflamatórios.

Introdução: a doença renal crônica (DRC) nos estágios iniciais não apresenta manifestações clínicas e, por isso, as pessoas somente procuram as unidades de saúde já na fase terminal da doença. Isso ainda é uma rotina no Brasil. Objetivo: identificar a prevalência de taxa de filtração glomerular estimada (TFGe) alterada e fatores associados em usuários do sistema único de saúde com Diabetes Mellitus e/ou com Hipertensão Arterial Sistêmica de alto e muito alto risco para doença cardiovascular. Materiais e Métodos: estudo transversal com prontuários de 331 usuários do Centro Estadual de Atenção Especializada no Centro-Oeste mineiro/ Minas Gerais/ Brasil, entre setembro de 2017 a junho de 2019. Realizou-se análise descritiva, univariada e regressão logística multivariada. Resultados: do total de participantes, 118 (35,6%) tiveram TFGe alterada. Identificou-se associação significativa da TFGe alterada com a idade: idosos ≥ 60 anos apresentaram 5,53 vezes mais chance de ter a TFGe alterada. Os participantes em uso da polifarmácia tiveram 2,64 vezes mais chance de terem a TFGe alterada. Discussão: em analogia com estudos semelhantes, registrou-se a ausência de acompanhamento da instalação e desenvolvimento da DRC nas fases iniciais, implicando em abordagem tardia e ações limitadas para preservação das funções renais. Conclusões: identificou-se alta prevalência de TFGe alterada (35,6%), sem registros nos prontuários que pudessem direcionar uma abordagem preventiva da degeneração das funções renais. A idade avançada e polifarmácia foram identificadas como variáveis independentes para alteração da função renal.
Introduction: Chronic kidney disease (CKD) does not have any clinical symptoms in the early stages and, therefore, most people only attend healthcare units when they are already in the terminal phase of the disease, which is still common in Brazil. Objective: To identify the prevalence of altered estimated glomerular filtration rate (eGFR) and associated factors in users of the unified health system suffering from diabetes mellitus and/or systemic hypertension at high risk of cardiovascular disease. Materials and Methods: A cross-sectional study was conducted based on the medical records of 331 users attending the State Specialty Care Center located in the west-central region of Minas Gerais, Brazil between September 2017 and June 2019. A descriptive univariate analysis and multivariate logistic regression were performed. Results: A total of 118 (35.6%) of the participants had altered eGFR. A significant association between altered eGFR and age was identified: older people ≥ 60 years old were 5.53 times more likely to have altered eGFR. Participants using polypharmacy were 2.64 times more likely to have altered eGFR. Discussion: In line with similar studies, a lack of follow-up on the initiation and development of CKD in the early stages was identified, implying a late approach and limited actions to preserve kidney function. Conclusions: A high prevalence of altered eGFR was identified (35.6%) with no records in the tables that could lead to a preventive approach to impaired kidney function. Advanced age and polypharmacy were identified as independent variables in the alteration of kidney function.
Introducción: La enfermedad renal crónica (ERC) en sus primeras etapas no presenta manifestaciones clínicas y, por lo tanto, la mayoría de las personas solo se acercan a las unidades de salud cuando ya están en la fase terminal de la enfermedad, lo cual sigue siendo habitual en Brasil. Objetivo: Identificar la prevalencia de la tasa estimada de filtración glomerular (TFG) alterada y los factores asociados en usuarios del sistema de salud único que sufran de diabetes mellitus y/o hipertensión sistémica de alto riesgo de enfermedad cardiovascular. Materiales y métodos: Se realizó un estudio transversal con las historias clínicas de 331 usuarios del Centro Estatal de Atención Especializada ubicado en el centro oeste de Minas Gerais, Brasil entre septiembre de 2017 y junio de 2019. Se realizaron un análisis univariado descriptivo y una regresión logística multivariante. Resultados: Del total de participantes, 118 (35,6%) tenían la TFG alterada. Se identificó una asociación significativa entre la alteración de la TFG y la edad: los ancianos ≥ 60 años tenían 5,53 veces más posibilidades de tener la TFG alterada. Los participantes que utilizaron la polifarmacia tenían 2,64 veces más probabilidades de que se alterara la TFG. Discusión: En consonancia con estudios similares, se registró la falta de seguimiento del inicio y el desarrollo de la ERC en las primeras etapas, lo que implica un enfoque tardío y acciones limitadas para preservar las funciones renales. Conclusiones: Se identificó una alta prevalencia de TFG alterada (35,6%) sin registros en las tablas que pudieran conducir a un enfoque preventivo de la degeneración de la función renal. La edad avanzada y la polifarmacia se identificaron como variables independientes en la alteración de la función renal.

RATIONALE, AIMS AND OBJECTIVES: In recent years, the use of proton pump inhibitors (PPI), especially omeprazole, has been associated with development of chronic kidney disease (CKD). These drugs are widely used worldwide. Although some studies have found an association between the use of PPI and the onset of acute renal failure and CKD. This study aims to analyze the association between the continuous use of omeprazole and the progression of CKD in adult and elderly individuals. METHOD: A retrospective cohort study was conducted with patients followed up at a nephrology clinic in Brazil, in 2016 and 2017. Information about clinical and sociodemographic data, health behaviors, and medication use were collected from all patients diagnosed with CKD through consultation of medical charts and the Brazilian health information system (SIS). The participants were allocated into two groups: users and non-users of omeprazole, and the progression of CKD was then evaluated for each group. In the bivariate analysis, the Mann-Whitney U test to compare the quantitative variables between groups, and the Pearson/Fisher two-tailed chi-square test to compare the categorical variables were applied. Multivariate analysis was performed using Cox regression. RESULTS: A total of 199 CKD patients were attended in the polyclinic, and of these, 42.7% were omeprazole users. There was a higher percentage of CKD progression in users (70.6%) compared to non-users (10.5%). The hazard ratio was 7.34 (CI: 3.94-13.71), indicating a higher risk of progression to worse stages of CKD in omeprazole users than in non-users. As for the other variables, no statistically significant difference was found between groups (p > 0.05). CONCLUSION: An association between omeprazole use and progression of CKD stage was identified, showing a higher risk of disease evolution among omeprazole users.

Intoxications represent a serious public health problem. According to the World Health Organization, 193,000 deaths per year are caused by unintended intoxications worldwide. This study aims to know the profile of intoxications at the 24-hour Emergency Service Unit in Divinópolis, in the state of Minas Gerais. This is a descriptive study in which the study population chosen were all patients treated for intoxications in the period from 2017 to 2018, registered in the health service; 421 cases of intoxications were recorded. The female gender was the most prevalent, and the age group with the most cases was 21 to 30 years. The main circumstance found was attempted suicide (83.1%), and the main causative agent was drugs (76.5%), with benzodiazepines being the main class responsible for intoxications. The most used treatment was gastric lavage and activated charcoal. This study demonstrates that knowledge about the city's intoxication profile is important for the development of treatment and patient management methods to better suit the demands of the municipality.

OBJECTIVE: To evaluate if the recommendations of appropriate health care for Chronic Kidney Disease (CKD) are implemented in patients with Diabetes Mellitus (DM) and Systemic Arterial Hypertension (SAH). METHODS: This is a descriptive study conducted between January and March 2019 in Divinópolis, in the Brazilian state of Minas Gerais. Patients aged 18 years or older with CKD, DM and/or SAH were followed up at the municipal nephrology outpatient clinic. An interview was conducted using a structured questionnaire to assess care, which was categorized as adequate or inadequate, based on the health care recommendations of the national guidelines for care of patients with CKD. RESULTS: 42 participants with CKD participated in the study. All participants had SAH and 42.9% (nâ¯=â¯18) also had DM. It was evidenced that 81.0% (nâ¯=â¯34) of the individuals with CKD had adequate health care, especially among patients in earlier stages (3A and 3B) and those who progressed to renal replacement therapy. However, 80.0% (nâ¯=â¯8) of the participants in the intermediate stage (stage 4) were inadequately followed up by the nephrologist and multidisciplinary team. CONCLUSIONS: Patients in intermediate stages do not receive follow-up with a multidisciplinary team at the recommended frequency. The preventive approach of the progression of renal disease in the intermediate stage in the studied municipality was not within the recommendations of the Ministry of Health.

INTRODUCTION: We analyzed the distribution and frequency of glomerular diseases in patients biopsied between 1992 and 2016 in centers that make up the AMICEN (Minas Gerais Association of Nephrology Centers). METHODS: We analyzed the biopsy reports of patients from 9 AMICEN nephrology centers. We took note of their age, gender, ultrasound use, post-biopsy resting time, whether the kidney was native or a graft, number of glomeruli and indication for the biopsy. The kidney biopsy findings were broken down into four categories: glomerular and non-glomerular diseases, normal kidneys and insufficient material for analysis. Those patients diagnosed with glomerular diseases were further divided into having primary or secondary glomerular diseases. RESULTS: We obtained 582 biopsy reports. The median age was 38 years (1 to 85). The number of glomeruli varied between 0 and 70 (median = 13.0). In total, 97.8% of the biopsies were ultrasound guided. The main indication was nephrotic syndrome (36.9%), followed by hematuria-proteinuria association (16.2%). Primary glomerular diseases proved to be the most frequent (75.3%), followed by secondary diseases (24.7%). Among the primary glomerular diseases, FSGS was found at a higher frequency (28.8%), while among the secondary diseases, SLE was the most prevalent (42.4%). Regarding prevalence findings, those for both primary and secondary diseases were similar to those found in the large Brazilian registries published thus far. CONCLUSION: Glomerular disease registries are an important tool to identify the prevalence of such disease in regions of interest and can serve as an instrument to guide public policy decisions concerning the prevention of terminal kidney diseases.

RESUMO INTRODUÇÃO: Analisamos a distribuição e frequência de doenças glomerulares de pacientes biopsiados entre 1992 e 2016 em centros que compõem a Amicen (Associação de Minas Gerais de Nefrologia). MÉTODOS: Analisamos os relatórios de biópsia de pacientes de nove centros de nefrologia da Amicen. Observamos idade, gênero, uso de ultrassom, tempo de descanso pós-biópsia, se o rim era nativo ou um enxerto, número de glomérulos e indicação para a biópsia. Os achados da biópsia do rim foram divididos em quatro categorias: doenças glomerulares e não glomerulares, rins normais e material insuficiente para análise. Os pacientes diagnosticados com doenças glomerulares foram ainda divididos em doenças glomerulares primárias ou secundárias. RESULTADOS: Obtivemos 582 relatórios de biópsia. A idade mediana foi de 38 anos (1 a 85). O número de glomérulos variou entre zero e 70 (mediana = 13,0). No total, 97,8% das biópsias foram guiadas por ultrassom. A principal indicação foi síndrome nefrótica (36,9%), seguida de associação hematúria-proteinúria (16,2%). As doenças glomerulares primárias revelaram-se as mais frequentes (75,3%), seguidas de doenças secundárias (24,7%). Entre as doenças glomerulares primárias, o FSGS foi encontrado em maior frequência (28,8%), enquanto nas doenças secundárias, o lúpus eritematoso sistêmico foi o mais prevalente (42,4%). Quanto aos achados de prevalência, aqueles para doenças primárias e secundárias foram semelhantes aos encontrados nos grandes registros brasileiros publicados até o momento. CONCLUSÃO: Os registros de doenças glomerulares são uma ferramenta importante para identificar a prevalência dessas doenças em regiões de interesse e pode servir como um instrumento para orientar decisões de políticas públicas relativas à prevenção de doenças renais terminais.

Objective To analyzed the association of quality of life and compliance to drug treatment in chronic kidney disease patients. Methods The Short Form Health Survey was used to evaluate the quality of life of these patients, and the therapeutic complexity index was verified. The Morisky-Green test and the Brief Medication Questionnaire were applied to check compliance to drug therapy. Results A total of 197 patients were included. The Morisky-Green test and Brief Medication Questionnaire showed that most patients had low compliance to treatment (50.3% and 80.6%, respectively). Compliance was highly associated with gender (male) and slightly associated with complexity of therapy, mental health, and social aspects. Conclusion We observed a slight association between compliance to pharmacotherapy and quality of life and complexity of therapy, and a strong association with gender.

INTRODUCTION: Chronic kidney disease (CKD) is a worldwide public health alarming problem. OBJECTIVE: This study investigated the estimated prevalence of kidney disease in diabetic and high-risk hypertensive patients to cardiovascular disease registered in Hiperdia program of a city of southeast of Brazil. METHODS: It is a transversal study conducted between May 2014 and August 2015. The study has included randomly 243 diabetic and high-risk hypertensive patients to cardiovascular disease which were originally referred from primary health care to the Hiperdia. CKD was classified based on cause, Glomerular Filtration Rate (GFR), and albumin creatinine ratio (ACR). Were considered abnormalities GFR < 60 mL/min/1.73m2 and/or ACR ≥ 30 mg/g. RESULTS: Of the 243 patients, 89 (36.6%) showed alterations in renal function markers in the first collection. Of these, 60 patients had a GFR < 60 mL/min/1.73 m2 and 25 the GFR was < 45 mL/min/1.73 m2. The ACR was ≥ 30 mg/g in 43 patients and eight of the values were > 1000 mg/g. In 15 patients studied were found both changes. Of the 89 participants with abnormal renal function markers in the first collection 63 held the second test and 42 kept the changes being diagnosed with CKD. None of these patients had prior knowledge of the diagnosis of kidney disease and the need for consultation with the nephrologist. CONCLUSION: The prevalence of CKD was 17.3% of disease in the population studied.
