Caracterización del paciente diabético como antecedente para una intervención educativa / Characterization of diabetic patients as a background for an educational intervention

Introducción: La diabetes mellitus es una enfermedad no transmisible con una elevada comorbilidad, sobre todo, vinculada a la enfermedad renal crónica. La caracterización del paciente diabético, según variables epidemiológicas y los conocimientos de la enfermedad renal crónica que presentan, deben preceder a la valoración clínica y a la intervención educativa dirigida a modificar estilos de vida como parte de la atención primaria de salud. Objetivos: Caracterizar a pacientes diabéticos del Policlínico Santa Clara, según variables epidemiológicas seleccionadas, y la comorbilidad vinculada con la enfermedad renal crónica. Métodos: Se realizó un estudio descriptivo-exploratorio a los pacientes diabéticos en el consultorio médico de la familia 16-11 del Policlínico Santa Clara, de octubre del 2019 a junio del 2022. La población estuvo conformada por 79 pacientes diabéticos y la muestra por 60, según criterios de inclusión y exclusión. Se utilizaron técnicas de análisis estadístico: análisis de frecuencias simples, estadística descriptiva y la prueba de independencia de Chi cuadrado. Resultados: Predominó el sexo masculino; grupo etario de 55-59; diabetes mellitus tipo 2 y cifras elevadas de tensión arterial correlacionadas con la diabetes. Además, existió un nivel bajo de conocimientos acerca de las enfermedades renales crónicas. Conclusiones: Los resultados obtenidos permiten confirmar la relevancia de este tipo de estudios para elevar el nivel de conocimientos sobre la relación entre el padecimiento de diabetes mellitus y la enfermedad renal crónica, para contribuir a mejorar la calidad de vida de este grupo poblacional a través de una intervención educativa previamente orientada.

Introduction: diabetes mellitus is a non-communicable disease with high comorbidity and especially linked to chronic kidney disease. Characterization of diabetic patients according to epidemiological variables and knowledge of their chronic kidney disease must precede the clinical assessment and educational intervention aimed at modifying lifestyles as part of primary health care. Objectives: to characterize diabetic patients from Santa Clara Polyclinic according to selected epidemiological variables as well as the comorbidity linked to chronic kidney disease. Methods: a descriptive exploratory study was carried out on diabetic patients belonged to the 16-11 doctor's office in Santa Clara Polyclinic from October 2019 to June 2022. The population was made up of 79 diabetic patients and 60 formed the sample according to inclusion and exclusion criteria. Statistical analysis techniques such as descriptive statistics, simple frequency analysis and the Chi- square independence test were used. Results: males, age group 55-59 years, type 2 diabetes mellitus and high blood pressure levels correlated with diabetes predominated. Besides, a low level of knowledge on chronic kidney diseases was identified. Conclusions: the obtained results confirm the relevance of this type of studies to raise the level of knowledge on the relationship between diabetes mellitus and chronic kidney disease in order to contribute to the improvement of the quality of life of this population group through a previously oriented educational intervention.

Diplejía facial en paciente con nefropatía por virus de inmunodeficiencia humana

Introducción: El síndrome de Guillain-Barré comprende un grupo heterogéneo de polirradiculoneuropatías inflamatorias agudas autoinmunes, las cuales se caracterizan por debilidad simétrica de extremidades con pérdida de reflejos miotáticos. Presenta gran variabilidad clínica, donde la afectación facial es habitual, sin embargo, incluye manifestaciones atípicas que dificultan el diagnóstico temprano de la enfermedad. Objetivo: Describir el comportamiento de un caso atípico de diplejía facial en un paciente con nefropatía por virus de inmunodeficiencia humana. Caso clínico: Se presentó el caso de un paciente portador de nefropatía por virus de la inmunodeficiencia humana, que comenzó con parálisis facial bilateral, como forma de presentación atípica de este síndrome. Acudió a los servicios de salud refiriendo decaimiento marcado, náuseas, vómitos, hipo y dos deposiciones líquidas. Se realizaron estudios que corroboran el diagnóstico. El tratamiento empleado facilitó la recuperación paulatina de la afección. Conclusiones: El diagnóstico precoz de las variantes atípicas de presentación del síndrome, permite un tratamiento oportuno, donde las posibilidades de complicaciones en el paciente son reducidas, así como la mortalidad asociada a la enfermedad.

Introduction: Guillain-Barré Syndrome comprises a heterogeneous group of autoimmune acute inflammatory polyradiculoneuropathies, which are characterized by symmetrical limb weakness with loss of stretch reflexes. It presents great clinical variability, where facial involvement is common; however, it includes atypical manifestations that make early diagnosis of the disease difficult. Objective: To describe the behavior of an atypical case of facial displejía in a patient with nephropathy due to Human Immunodeficiency Virus. Case report: A case of a patient with HIV nephropathy is presented, which begins with bilateral facial paralysis, as an atypical presentation of this syndrome. The patient went to the health services reporting marked weakness, nausea, vomiting, hiccups and two liquid stools. Studies were performed that corroborate the diagnosis. The treatment used facilitated the gradual recovery of the condition. Conclusions: Early diagnosis of the atypical presentation variants of the syndrome allows timely treatment, where the chances of complications in the patient are reduced, as well as the mortality associated with the disease.

The influence of hemodialysis on intracranial pressure waveform in patients with chronic kidney disease: an observational study

ABSTRACT BACKGROUND: Among the complications related to chronic kidney disease (CKD), those of a neurological nature stand out, and for a better quality of life for patients, the diagnosis and treatment of these complications is fundamental. OBJECTIVES: This study aimed to assess the effect of hemodialysis on intracranial pressure waveform (ICPw) in patients with chronic kidney disease undergoing hemodialysis and those who are not yet undergoing substitutive therapy. DESIGN AND SETTING: An observational study was conducted in two stages at a kidney replacement therapy center in Brazil. The first was a longitudinal study and the second was a cross-sectional study. METHODS: Forty-two patients on hemodialysis were included in the first stage of the study. In the second stage, 226 participants were included. Of these, 186 were individuals with chronic kidney disease (who were not undergoing substitutive therapy), and 40 did not have the disease (control group). The participants' intracranial compliance was assessed using the non-invasive Brain4care method, and the results were compared between the groups. RESULTS: There was a significant difference between the hemodialysis and non-hemodialysis groups, with the former having better ICPw conditions. CONCLUSIONS: Hemodialysis influenced the improvement in ICPw, probably due to the decrease in the patients' extra-and intracellular volumes. Furthermore, ICPw monitoring can be a new parameter to consider when defining the moment to start substitutive therapy.

Síndrome de Currarino incompleto. Presentación de un caso

El síndrome de Currarino es una enfermedad hereditaria y de baja incidencia, compuesta por una tríada: estenosis anal, malformación sacro coccígea y masa presacra. Puede cursar desapercibido hasta la adultez y generar subdiagnósticos. Se describe un paciente de 75 años, masculino, piel negra, de procedencia urbana y con antecedentes de hipertensión arterial, quien acudió al hospital por presentar hematuria, dolor en fosa lumbar izquierda y estreñimiento. Se realizaron estudios imagenológicos, como ultrasonido, tomografía de abdomen y resonancia magnética lumbosacra, los cuales condujeron al diagnóstico de tumor renal, síndrome de Currarino incompleto (dado por dos elementos de la triada: malformación sacro coccígea y masa presacra) asociado a otra enfermedad malformativa raquimedular, médula anclada. Son pocos los casos reportados en el mundo (casi 300), por lo que se considera una entidad rara, pero de fácil diagnóstico debido al advenimiento de las nuevas tecnologías en el campo de la imagenología.

Currarino syndrome is a hereditary disease with a low incidence, composed of a triad: anal stenosis, sacrococcygeal malformation and presacral mass. It can go unnoticed until adulthood and generate subdiagnoses. A 75-years-old male, black-skinned, urban origin patient with a history of arterial hypertension is described, who attended the hospital presenting hematuria, pain in the left lumbar fossa, and constipation. Radiological studies such as ultrasound, abdominal tomography and lumbosacral magnetic resonance were performed, which led to the diagnosis of a renal tumor, incomplete Currarino syndrome (given by two elements of the triad: sacrococcygeal malformation and presacral mass) associated with another spinal cord malformation disease, tethered cord. There are few cases reported in the world (almost 300), so it is considered a rare entity, but easy to diagnose due to new imaging technologies.

Frailty syndrome and end-stage kidney disease outcomes at a Latin American dialysis center

Introduction. Frailty syndrome generates a high risk of adverse outcomes and mortality, and its prevalence is elevated in patients with end-stage kidney disease. Few studies have reported the prevalence and outcomes of frailty in populations from less developed countries. Objective. To identify the clinical outcomes and factors associated with the frailty syndrome in patients with stage five chronic kidney disease who started renal replacement therapy - both hemodialysis and peritoneal dialysis- in a dialysis center in Bucaramanga, Colombia. Materials and methods. This was a prospective study of patients with end-stage kidney disease who initiated dialysis at a center in Colombia and had a twelve-month follow-up. Results. The overall frailty prevalence was 50.47% and two out of three patients older than 65 years had the syndrome. We found significantly higher followup mortality among patients with frailty: odds ratio of 2.95 (CI: 1.07- 8.13; p=0.036) in unadjusted analysis. Conclusions. Literature shows that compared to developed nations, Latin American adults are facing a higher prevalence of chronic diseases, and frailty syndrome is increasing. In this study, according to the FRAIL scale, having a frailty syndrome predicts a higher mortality; hypoalbuminemia and low creatinine levels at the beginning of dialysis could act as predictors of its diagnosis.

Introducción. El síndrome de fragilidad implica un alto riesgo de desenlaces adversos y mortalidad, y tiene una prevalencia elevada en pacientes con enfermedad renal en etapa terminal. Hay pocos estudios que investiguen la prevalencia y los desenlaces de este síndrome de fragilidad en las poblaciones de los países en desarrollo. Objetivo. Identificar los desenlaces clínicos y los factores asociados al síndrome de fragilidad en los pacientes con enfermedad renal crónica en estadio cinco que inician terapia de reemplazo renal -con hemodiálisis o diálisis peritoneal- en un centro de diálisis de Bucaramanga, Colombia. Materiales y métodos. Se trató de un estudio prospectivo de pacientes con enfermedad renal en etapa terminal que iniciaron diálisis en un centro de Colombia y a quienes se les hizo seguimiento durante doce meses. Resultados. La prevalencia global del síndrome de fragilidad fue del 50,47 % y dos de cada tres pacientes mayores de 65 años lo presentaban. Se encontró una mortalidad significativamente mayor entre los pacientes con síndrome de fragilidad: razón de probabilidad de 2,95 (IC:1,07-8,13; p=0,036) en el análisis no ajustado. Conclusiones. La literatura muestra que, en comparación con los países desarrollados, los adultos latinoamericanos presentan una mayor prevalencia de enfermedades crónicas y un aumento progresivo del síndrome de fragilidad. En este estudio, la fragilidad -según la escala FRAIL- predijo una mayor mortalidad. Además, la hipoalbuminemia y los niveles bajos de creatinina al inicio de la diálisis podrían actuar como elementos predictores de su diagnóstico.

Exposure of patients with chronic kidney disease on dialysis to pesticides / Exposição de pacientes com doença renal crônica em tratamento dialítico aos agrotóxicos

ABSTRACT Introduction: Pesticides can trigger kidney disease. Objective: To describe the exposure to pesticides of patients with chronic kidney disease on dialysis. Methods: Quantitative and descriptive field research, with 90 patients with chronic kidney disease on dialysis in two hemodialysis units in the state of Santa Catarina, through the application of a structured questionnaire. Participants were divided into two groups: with and without exposure to pesticides. The questionnaire was applied in hemodialysis clinics during treatment. Laboratory test values were collected from clinical records. Data were analyzed using descriptive statistics and association using the chi-square test. For laboratory test data, a comparison of means was performed using the unpaired Student's t-test between the groups. Results: The mean age of exposed participants was 58 years (±13.7; minimum = 23; maximum = 75) and that of non-exposed participants was 64 years old (±13.9; minimum = 35; maximum = 96). Of the 90 patients, 30% were exposed to pesticides. The mean exposure time was 6.7 ± 3.8 hours/day. There was a statistically significant association between the preparation of the mixture with pesticides and diabetes (p ≤ 0.048). There was no statistically significant difference between the results of laboratory tests in the exposed and non-exposed groups. Conclusion: This study shows that pesticides can be triggering factors for chronic kidney disease (CKD); however, we must expand research in this field to prove the relationship between exposure to pesticides and CKD.

Resumo Introdução: O uso de agrotóxicos pode desencadear doença renal. Objetivo: Descrever a exposição a agrotóxicos de pacientes com doença renal crônica em tratamento dialítico. Métodos: Pesquisa de campo, quantitativa e descritiva, com 90 portadores de doença renal crônica em tratamento dialítico em duas unidades de hemodiálise no estado de Santa Catarina, por meio da aplicação de um questionário estruturado. Os participantes foram divididos em dois grupos: sem e com exposição a agrotóxicos. O questionário foi aplicado nas clínicas de hemodiálise durante o tratamento. Foram coletados valores de exames laboratoriais dos prontuários clínicos. Os dados foram analisados pela estatística descritiva e associação pelo teste qui-quadrado. Para os dados dos exames laboratoriais, foi realizada comparação de médias pelo teste t de Student não pareado entre os grupos. Resultados: A idade média dos participantes expostos foi de 58 anos (±13,7; mínimo = 23; máximo = 75) e a dos não expostos, de 64 anos (±13,9; mínimo = 35; máximo = 96). Dos 90 pacientes, 30% foram expostos a agrotóxicos. O tempo médio de exposição foi de 6,7 ± 3,8 horas/dia. Houve associação estatística significativa entre o preparo da calda com agrotóxicos e a presença de diabetes (p ≤ 0,048). Não houve diferença estatística significativa entre os resultados dos exames laboratoriais do grupo exposto e do não exposto. Conclusão Esta pesquisa evidencia que os agrotóxicos podem ser fatores desencadeadores da doença renal crônica (DRC), entretanto sugere-se ampliar pesquisas na área que possam comprovar a relação entre exposição a agrotóxicos e DRC.

Endovascular treatment of intrarenal aneurysms bleeding and angiomyolipomas in a patient with tuberous sclerosis and polycystic kidney disease / Tratamento endovascular de sangramentos e angiomiolipomas de aneurismas intrarrenais em um paciente com esclerose tuberosa e doença renal policística

Abstract Tuberous sclerosis complex (TSC) and autosomal dominant polycystic kidney disease (ADPKD) are conditions related to renal failure that can rarely occur in association as a contiguous gene syndrome. Angiomyolipomas (AMLs) are renal tumors strongly related to TSC that may rupture and cause life-threatening bleedings. We present a patient with TSC, ADPKD, and renal AMLs with persistent hematuria requiring blood transfusion. The persistent hematuria was successfully treated through endovascular embolization, a minimally invasive nephron sparing technique.

Resumo O complexo de esclerose tuberosa (CET) e a doença renal policística autossômica dominante (DRPAD) são condições relacionadas à insuficiência renal que raramente podem ocorrer em associação como uma síndrome do gene contíguo. Angiomiolipomas (AMLs) são tumores renais fortemente relacionados ao CET que podem romper-se e causar hemorragias com risco de vida. Apresentamos um paciente com CET, DRPAD e AMLs renais com hematúria persistente que requer transfusão sanguínea. A hematúria persistente foi tratada com sucesso por meio de embolização endovascular, uma técnica de preservação do néfron minimamente invasiva.

A case of colonoscopy-induced Wunderlich's syndrome in a hemodialysis patient: coincidence or association? / Um caso de síndrome de Wunderlich induzida por colonoscopia em um paciente em hemodiálise: coincidência ou associação?

Abstract Wunderlich syndrome, or spontaneous renal hemorrhage (SRH), is a rare condition encountered in patients undergoing chronic hemodialysis (HD) usually attributed to acquired cystic kidney disease (ACKD) among other causes. In the literature, colonoscopy is associated with splenic injuries, and renal hemorrhage has not been previously described. Management can range from conservative treatment to angiographic embolization or exploration and nephrectomy. Here we report an unusual case of a 54-year-old woman HD patient who presented with SRH within a few days of colonoscopy. The reason of SRH was rupture of an ACKD cyst. We assumed that colonoscopy was a provoking factor and elaborated hypotheses for its etiopathogenesis. The patient underwent successful left nephrectomy. The importance of this case lies in the fact that colonoscopy is not always an innocent procedure in HD patients, and could be complicated by renal cyst hemorrhage.

Resumo A síndrome de Wunderlich, ou hematoma perirrenal espontâneo (HPE), é uma condição rara encontrada em pacientes submetidos à hemodiálise crônica (HD) geralmente atribuída à doença renal cística adquirida (DRCA), entre outras causas. Na literatura, a colonoscopia está associada a lesões esplênicas, e o hematoma renal não foi descrito anteriormente. O manejo pode variar de tratamento conservador a embolização angiográfica ou exploração e nefrectomia. Aqui relatamos um caso incomum de uma paciente em HD de 54 anos de idade que se apresentou com HPE dentro de poucos dias após a colonoscopia. O motivo do HPE foi a ruptura de um cisto de DRCA. Consideramos que a colonoscopia foi um fator provocador e elaboramos hipóteses para sua etiopatogenia. A paciente foi submetida a uma nefrectomia esquerda bem-sucedida. A importância deste caso reside no fato de que a colonoscopia nem sempre é um procedimento inocente em pacientes em HD, e pode ser complicada por hemorragia do cisto renal.

Kidney Disease in Ankylosing Spondylitis: a case series and review of the literature / Doença Renal na Espondilite Anquilosante: uma série de casos e revisão da literatura

Abstract Background Kidney disease is a rare manifestation of ankylosing spondylitis (AS) and its pathological alterations remain poorly described. The aim of this study was to investigate the clinical presentation and pathological alterations on kidney biopsy of AS patients and review and discuss the current literature on the issue. Methods: We retrospectively studied the clinical presentation and kidney pathological alterations of 15 Caucasian AS patients submitted to kidney biopsy between October 1985 and March 2021. Results: Patients were predominantly male (66.7%) with median age at the time of kideney biopsy of 47 years [IQR 34 - 62]. Median serum creatinine at presentation was 1.3 mg/dL [IQR 0.9 - 3] and most patients also had either proteinuria (85.7%) and/or hematuria (42.8%). The most common indication for kidney biopsy was nephrotic syndrome (33.3%), followed by acute or rapidly progressive kidney injury (20%) and chronic kidney disease of unknown etiology (20%). Chronic interstitial nephritis (CIN) (n=3) and AA amyloidosis (n=3) were the most common diagnosis. Others included IgA nephropathy (IgAN) (n=2), focal segmental glomerulosclerosis (n=2), membranous nephropathy (n=1), and immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN)(n=1). Conclusions: We present one of the largest series of biopsy-proven kidney disease in Caucasian AS patients. We found a lower prevalence of IgAN than previously reported in Asian cohorts. We found a higher prevalence of CIN and a lower prevalence of AA amyloidosis than that described in previous series of Caucasian patients. We also present the first case of AS-associated IC-MPGN.

Resumo Antecedentes: A doença renal é uma manifestação rara de espondilite anquilosante (EA) e as suas alterações patológicas permanecem pouco descritas. O objetivo deste estudo foi investigar a apresentação clínica e alterações patológicas na biópsia renal de doentes com EA bem como rever e discutir a literatura atual sobre o assunto. Métodos: Estudamos retrospectivamente a apresentação clínica e alterações patológicas renais de 15 doentes caucasianos com EA submetidos a biópsia renal entre Outubro de 1985 e Março de 2021. Resultados: Os doentes eram predominantemente homens (66,7%) com idade mediana no momento da biópsia de 47 anos [IIQ 34 - 62]. A creatinina sérica mediana na apresentação foi de 1,3 mg/dL [IIQ 0,9 - 3] e a maioria dos pacientes apresentava também proteinúria (85,7%) e/ou hematúria (42,8%). A indicação mais comum para biópsia renal foi a síndrome nefrótica (33,3%), seguida de lesão renal aguda ou rapidamente progressiva (20%) e doença renal crónica de etiologia desconhecida (20%). A Nefrite intersticial crónica (NIC) (n=3) e a amiloidose AA (n=3) foram os diagnósticos mais comuns. Outros incluíram nefropatia por IgA (NIgA) (n=2), glomeruloesclerose segmentar focal (n=2), nefropatia membranosa (n=1) e glomerulonefrite membranoproliferativa mediada por imunocomplexos (GNMP-IC) (n=1). Conclusões: Apresentamos uma das maiores séries de doenças renais comprovadas por biópsia em doentes caucasianos com EA. Encontramos uma prevalência de NIgA menor do que a relatada anteriormente em coortes asiáticas. Encontramos uma maior prevalência de NIC e uma prevalência menor de amiloidose AA do que a descrita em séries anteriores de pacientes caucasianos. Também apresentamos o primeiro caso de GNMP-IC associada à EA.

Detección de ansiedad y depresión en el binomio receptor-donador durante el protocolo de trasplante renal / Anxiety and depression in the recipient-donor binomial during the kidney transplant protocol

ABSTRACT Introduction: Detection of anxiety and depression in the recipient-donor pair (BinRD) during the kidney transplant protocol (KT) is important to establish psychoeducational interventions that help achieve success during and after KT. Objective: To determine the presence of anxiety and depression symptoms in the BinRD during the RT protocol and to identify characteristics and associated factors. Methods: Cross-sectional study, including 174 binomials being evaluated for TR. The Beck Depression Scale (BDI-II) and the Hospital Anxiety and Depression Scale (HADS) were applied at the beginning of the RT protocol. Results: Anxiety and depression symptoms were more frequent in recipient candidates than in donors ([anxiety 39% vs 21%] [depression 46% vs 15%]) (p<0.0001). The recipients presented a higher risk of depression (OR=4.770, 95% CI 2.854-7.974, p<0.0001) and anxiety (OR=2.383, 95% CI 1.478-3.841, p<0.001). Undertaking hemodialysis in private units (OR 0.264, 95%CI 0.106-0.662, p=0.004) or being on automated peritoneal dialysis (OR 0.386, 95%CI 0.173-0.862, p=0.020 was associated with less anxiety in recipients. Conclusions: a high frequency of anxiety and depression symptoms in the BinRD, so it is important to offer effective psychological interventions focused especially on the recipient during the donation evaluation process.

RESUMEN Introducción: La detección de ansiedad y depresión en el binomio receptor-donador (BinRD) durante el protocolo de trasplante renal (TR) es importante, para establecer intervenciones psicoeducativas que ayuden a lograr el éxito durante y después del TR. Objetivo: Determinar presencia de síntomas de ansiedad y depresión en el BinRD durante el protocolo de TR e identificar características y factores asociados. Métodos: Estudio transversal, incluye 174 binomios en evaluación para TR. Se aplicó la Escala de Depresión de Beck (BDI-II) y la Escala de Ansiedad y Depresión Hospitalaria (HADS) al inicio del protocolo de TR. Resultados: Síntomas de ansiedad y depresión fueron más frecuentes en candidatos a receptores que en donadores ([ansiedad 39% vs 21%] [depresión 46% vs 15%]) (p<0.0001). Los receptores, presentaron mayor riesgo de depresión (OR=4.770, IC 95% 2.854-7.974, p<0.0001) y ansiedad (OR=2.383, IC 95% 1.478-3.841, p<0.001). Realizarse hemodiálisis en unidades privadas (OR 0.264, IC95% 0.106-0.662, p=0.004) o estar en diálisis peritoneal automatizada (OR 0.386, IC95% 0.173-0.862, p=0.020 se asoció a menor ansiedad en receptores. Conclusiones: Se evidenció una alta frecuencia de síntomas de ansiedad y depresión en el BinRD, por lo que es importante ofrecer intervenciones psicológicas eficaces enfocadas especialmente al receptor durante el proceso de evaluación para la donación.

Percutaneous treatment of simple renal cysts with 24-h-interval ethanol sclerotherapy / Tratamento percutâneo de cistos renais simples por escleroterapia com etanol em intervalo de 24 horas

Abstract Objective: To investigate the efficacy of 24-h interval multiple-session ethanol sclerotherapy for the treatment of simple renal cysts. Materials and Methods: The study sample included 58 patients (mean age, 65.37 ± 11.95 years). We included 76 simple renal cysts that were treated with percutaneous aspiration with a minimum of two sessions of 95% ethanol sclerotherapy in a 24-h interval between sessions. Patients were evaluated at 1, 3, and 6 months after the intervention for the efficacy of the treatment. Treatment success was defined as a complete regression of a cyst or a > 50% reduction in its volume, with no recurrence of symptoms. Results: The mean preprocedural cyst size was 72.98 ± 25.14 mm, and the mean preprocedural cyst volume was 205.76 ± 244.15 mL. The mean volume of ethanol used in the first sclerotherapy session was 62.76 ± 30.71 mL. The mean fluid accumulation in the cysts at the end of the first 24-h interval was 4.66 ± 7.13 mL. The mean quantity of ethanol used in the second sclerotherapy session was 26.48 ± 22.2 mL. A third sclerotherapy session was required in only 10 (13.2%) of the cysts. The mean follow-up period was 52.84 ± 37.83 months. The rate of complete regression was 97.4% for the whole sample at the end of the follow-up. Conclusion: Ethanol ablation with 24-h intervals is a safe and effective treatment option in the minimally invasive percutaneous treatment of simple renal cysts.

Resumo Objetivo: Demonstrar a eficácia da escleroterapia com etanol em sessões múltiplas em intervalos de 24 horas no tratamento de cistos renais simples. Materiais e Métodos: Foram avaliados 76 cistos renais simples de 58 pacientes (média de idade: 65,37 ± 11,95 anos) submetidos a aspiração percutânea e ao menos duas sessões de escleroterapia com etanol 95% num intervalo de 24 horas. Considerou- se sucesso de tratamento a regressão completa ou uma redução > 50% do volume do cisto, sem recorrência dos sintomas. Os pacientes foram reavaliados 1, 3 e 6 meses após o procedimento. Resultados: Antes do procedimento, a média do tamanho dos cistos foi de 72,98 ± 25,14 mm e a média do volume dos cistos foi de 205,76 ± 244,15 mL. A quantidade média de etanol utilizada na primeira sessão de escleroterapia foi de 62,76 ± 30,71 mL. A média de acúmulo de líquido ao final do intervalo de 24 horas foi de 4,66 ± 7,13 mL, sendo utilizada uma média de quantidade de etanol de 26,48 ± 22,2 mL na segunda sessão de escleroterapia. Uma terceira sessão de escleroterapia foi necessária em apenas 10 (13,2%) dos cistos. Na amostra geral, a taxa de regressão completa foi de 97,4%. O tempo médio de seguimento foi de 52,84 ± 37,83 meses. Conclusão: A ablação com etanol em intervalo de 24 horas é uma opção de tratamento segura, eficaz e minimamente invasiva no tratamento percutâneo de cistos renais simples.

Objective:To investigate the clinical effect of Shenqi Dihuang Decoction and Xiaochengqi Decoction enema combined with hemodialysis in the treatment of qi deficiency, blood stasis and dampness and turbidity in chronic kidney disease (CKD) stage 5.Methods:Randomized controlled trial. A total of 102 elderly CKD stage 5 patients with Qi and Yin deficiency and turbid poison inherent type were selected from May 2021 to January 2022 of the Beijing Longfu Hospital. The patients were divided into two groups by random number table method. Control group (51 cases) received hemodialysis treatment for 4 weeks, and the observation group (51 cases) received Shenqi Dihuang Decoction and Xiaochengqi Decoction enema combined with hemodialysis treatment for 4 weeks. The levels of BUN, SCr and β2-microglobulin (β2-MG), and K +, Ca 2+, P 3- content, hemoglobin were detected by automatic blood cell analyzer, and serum CRP and IL-6 levels were detected by latex enhanced immune scattering turbidimetry. The adverse reactions during the treatment and evaluate the clinical efficacy were observed and recorded. Results:During the treatment, 2 patients in the observation group withdrew from the study due to severe diarrhea, and other patients completed the study.

Fatores associados à autoavaliação de saúde bucal por adultos em hemodiálise / Factors associated with self-rated oral health in adults with hemodialysis

Resumo Introdução Pacientes com insuficiência renal crônica podem apresentar prejuízos em sua saúde bucal em decorrência da própria doença, do tratamento e das alterações de estilo de vida associadas. Objetivo Avaliar os fatores associados à autoavaliação de saúde bucal ruim entre adultos com insuficiência renal crônica submetidos à hemodiálise. Método Estudo transversal com 243 adultos submetidos à hemodiálise em um hospital do sul de Minas Gerais nos anos de 2013 e 2014. O desfecho foi avaliado pelo autorrelato da condição bucal dicotomizada em boa (ótima/boa) e ruim (regular/ruim/péssima). As variáveis independentes incluíram condições sociodemográficas, saúde geral, saúde bucal e uso de serviços odontológicos, a partir de informações coletadas por meio de questionário. A associação entre o desfecho e as variáveis independentes foi testada por meio de modelos logísticos múltiplos com inclusão hierarquizada de variáveis. Resultados A prevalência de autoavaliação de saúde bucal ruim foi de 35,4%. Os mais jovens (p = 0,015), os que se submetem à hemodiálise há menos tempo (p = 0,016), têm halitose (p <0,001), necessitam de tratamento odontológico (p <0,001) e tiveram a última consulta odontológica por motivo diferente de dor (p = 0,027) expressaram maiores chances de autoavaliação de saúde bucal ruim, independentemente de condições sociodemográficas e de saúde. Conclusão Condições sociodemográficas, tempo em hemodiálise, agravos à saúde bucal e uso de serviços odontológicos influenciaram a autoavaliação da saúde bucal dos adultos submetidos à hemodiálise.

Abstract Background Patients with chronic renal failure may have their oral health impaired as a result of the disease itself, its treatment, and its associated lifestyle alterations. Objective To assess the factors associated with poor self-rated oral health among adults with chronic renal failure treated by hemodialysis. Method This is a cross-sectional study with 243 adults undergoing hemodialysis in a hospital in Minas Gerais, Brazil in 2013-2014. The outcome was assessed by the self-report of oral health categorized into good (excellent/good) and bad (fair/bad / very bad). The independent variables included sociodemographic conditions, general health, oral health, and the use of dental services were collected through a structured questionnaire. The association between the outcome and the independent variables was tested using multiple logistic models with hierarchical inclusion of variables. Results The prevalence of poor self-rated oral health was 35.4%. The youngest (p = 0.015), those who have undergone hemodialysis in the shortest time (p = 0.016), have halitosis (p <0.001), need dental treatment (p <0.001), and had their last dental appointment not for pain (p = 0.027) expressed higher odds of poor self-rated oral health, independently of sociodemographic and health conditions. Conclusion Sociodemographic conditions, time on hemodialysis, oral impairments, and use of dental services affected the oral health self-assessment among adults undergoing hemodialysis.

Tasa de filtración glomerular como estimador de la hipertensión en enfermedades renales y cardiovasculares / Glomerular filtration rate as an estimator of renal and cardiovascular diseases such as hypertension

Introducción: Las fórmulas para la estimación de la tasa de filtración glomerular son fundamentales para estimar el curso de enfermedades renales; incluso ha sido de gran ayuda para obtener datos de prevalencia. Las ecuaciones comparadas con otros métodos son una forma económica y rápida para dar una estimación de la función renal. Objetivo: Describir la utilización de diferentes fórmulas para calcular la tasa de filtración glomerular relacionada con la hipertensión arterial y otras patologías renales y cardiovasculares. Metodología: Se realizó la búsqueda de artículos de investigación en bases de datos como PubMed, Science-Direct, Embase y otras, se estableció un tiempo de publicación entre los años 2018-2022 y se seleccionaron 42 artículos científicos relacionados con el tema. Resultados: La hipertensión arterial es una situación que incrementa el riesgo tanto de enfermedad cardiovascular como de deterioro de la función renal, por lo que en los pacientes hipertensos se espera una relación estrecha en la expresión de ambas patologías. Existen factores que alteran los valores de la creatinina sérica como la dieta, el ejercicio, la edad, el género, la masa muscular, enfermedades musculares y medicamentos. El impacto de la hipertensión en la función renal está descrito además de la relación entre el deterioro de la función renal y el incremento del riesgo cardiovascular; es por esto que en los últimos años la estimación de la función renal se ha incorporado como un marcador de morbilidad y mortalidad cardiovascular. Conclusiones: La estimación de la tasa de filtración glomerular es importante en varios contextos clínicos, en especial en aquellos pacientes con enfermedades que afectan la función glomerular, la creatinina es el biomarcador más usado a pesar de sus evidentes limitaciones.

Introduction: Formulas for estimating glomerular fil-tration rate are fundamental for estimating the course of renal diseases; they have even been of great help in obtaining prevalence data. Equations compared with other methods are an economical and fast way to give an estimation of renal function. Objective: Describe the use of different formulas to calculate the glomerular filtration rate related to high blood pressure and other kidney or cardiovascular pa-thologies. Methodology: Research articles were searched in da-tabases such as PubMed, Science-Direct, Embase and others, a publication time was established between the years 2018-2022 and 42 scientific articles related to the topic were selected. Results: Arterial hypertension is a situation that in-creases the risk of both cardiovascular disease and re-nal function deterioration, so in hypertensive patients a close relationship in the expression of both pathologies is expected. There are factors that alter serum creati-nine values such as diet, exercise, age, gender, muscle mass, muscle diseases and medications. The impact of hypertension on renal function has been described in addition to the relationship between the deterioration of renal function and the increase in cardiovascular risk; this is why in recent years the estimation of renal func-tion has been incorporated as a marker of cardiovascu-lar morbidity and mortality. Conclusions: The estimation of glomerular filtration rate is important in several clinical contexts, especia-lly in those patients with diseases that affect glomerular function; creatinine is the most widely used biomarker despite its obvious limitations

Extra-articular Manifestations of Chikungunya

ABSTRACT Chikungunya fever (CHIK) is a neglected tropical disease associated with chronic arthritis. CHIK is usually a self-limiting condition; however, extra-articular manifestations present as atypical illness in a minority of patients. These atypical features may mimic other conditions and potentially distract physicians from the true diagnosis. This review analyzes the evidence of many unusual extra-articular manifestations reported in cases of CHIK. Depending on the affected system, these unusual manifestations include encephalitis, myocarditis, acute interstitial nephritis, cutaneous manifestations, acute anterior uveitis, abdominal pain, and depression. In addition, coinfections and comorbidities may cause atypical illness and obscure the diagnosis. Further studies are required to clarify the pathophysiology and natural history of CHIK, as it remains a burdening condition. Exploring its atypical symptoms may be the missing scientific piece of this puzzle.

Validation of equations to estimate kidney function with and without adjustment by race/color in Brazilian adults (ELSA-Brazil) / Validação das equações para estimativa da função renal com e sem ajuste por raça/cor em adultos brasileiros (ELSA-Brasil)

ABSTRACT Objective: To evaluate accuracy and agreement between creatinine clearance (CrCl) measured in 12-h urine and glomerular filtration rate (GFR) calculated by the Modification of Diet in Renal Disease (MDRD-4) and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formulas, with and without adjustment for race/color. Methods: Baseline data from the Longitudinal Study of Adult Health (ELSA-Brazil) in adults (35-74 years of age) of both genders were used. Serum creatinine was measured in fasting blood and urinary creatinine was measured in an overnight 12-h urine collect. The agreement between CrCl and the calculated GFR was analyzed by the Bland-Altman method. One-way analysis of variance (ANOVA) with race/color factor was used to verify differences between means of CrCl and GFR with and without correction for race/color. Statistical significance was accepted for p<0.05. Results: From 15,105 participants in the ELSA-Brazil, 12,813 had a validated urine collect. The Bland-Altman diagrams showed that formulas and CrCl agree with each other with a better accuracy for GFR <90 mL/.min x 1.73m2. The adjustment by race/color increased data dispersion. In this range, one-way ANOVA of CrCl with race/color factor showed similarity between groups (p=0.27). Conclusion: MDRD-4 and CKD-EPI are useful formulas for screening cases of chronic kidney disease, and correction by race/color, only in blacks or in black and brown subjects, proved to be unnecessary and reduced the reliability of the equations.

RESUMO Objetivo: Avaliar a acurácia e a concordância entre o clearance de creatinina (ClCr) medido na urina de 12 h e a taxa de filtração glomerular (TFG) calculada pelas fórmulas Modification of Diet in Renal Disease (MDRD-4) e Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), com e sem ajuste por raça/cor. Métodos: Foram usados dados da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil), em adultos (35-74 anos) de ambos os sexos. A creatinina sérica foi medida no sangue em jejum e a creatinina urinária foi medida na urina de 12 h coletada no período noturno. A concordância entre o ClCr e a TFG calculada pelas fórmulas foi analisada pelo método de Bland-Altman. Análise de variância (ANOVA) de uma via com fator raça/cor foi usada para comparar médias do ClCr e da TFG calculadas com e sem ajuste por raça/cor. A significância estatística foi aceita para p<0,05. Resultados: Dos 15.105 participantes do ELSA-Brasil, 12.813 tiveram a coleta urinária de 12 h validada. Os diagramas de Bland-Altman mostraram que as fórmulas e o ClCr concordam entre si e têm melhor acurácia para TFG <90 mL/min/1,73m2, e que o ajuste por raça/cor aumenta a dispersão dos dados. Nessa faixa, a ANOVA de uma via do ClCr com fator raça/cor mostrou semelhança entre grupos (p=0,27). Conclusão: MDRD-4 e CKD-EPI são fórmulas adequadas para rastreamento da doença renal crônica na população brasileira, sendo desnecessário o ajuste por raça/cor para o uso desses instrumentos, uma vez que a introdução do ajuste tanto em pretos quanto em pretos e pardos diminuiu a acurácia dos métodos.
