ABSTRACT

Urolithiasis has a high incidence among confined sheep. It is multifactorial and may cause economic damage. Our aim was to determine the capacity of urinary acidification using ammonium chloride in sheep. Twenty-five 3-month-old male sheep were confined and randomly divided into three groups; the G200 and G500 groups received 200mg/kg/GW and 500mg/kg/GW of ammonium chloride daily for 56 consecutive days, respectively, whereas the CG group did not receive ammonium chloride. Sampling times and clinical evaluation were performed weekly, starting from the 14th day of confinement (M1 or immediately before administering ammonium chloride) until the 17th day (M9) of the feedlot. Hemogasometry, biochemical examination of serum urea and creatinine concentration and ultrasound evaluation of the urinary tract were performed. The urinalysis indicated a higher incidence of ammonium magnesium phosphate crystals at the beginning of the study, showing a migration to urate crystal formation, mainly in the G500 group because of urinary acidification. No hemogasometric, serum biochemistry, ruminal fluid, or ultrasonographic changes were observed. Urinary acidification was achieved and maintained after M7 during the administration of ammonium chloride in the G500 group, but not in the other study groups.(AU)


A urolitíase apresenta alta incidência em ovinos confinados, etiologia multifatorial, e pode causar prejuízo econômico. O objetivo do presente estudo foi determinar a capacidade da acidificação urinária mediante o uso de cloreto de amônio em ovinos. Foram utilizados 25 ovinos de três meses de idade, confinados e divididos aleatoriamente em três grupos: grupo CG (controle) não recebeu cloreto de amônio; grupo G200 (200mg/kg/PV) recebeu cloreto de amônio por 56 dias consecutivos; grupo G500 (500mg/kg/PV) recebeu cloreto de amônio por 56 dias consecutivos, administrados diariamente por via oral. Os momentos (M) de colheita de amostras e de avaliação clínica foram realizados com intervalo de sete dias, sendo M1 (imediatamente antes do cloreto de amônio), M2 (sete dias após) até M9, totalizando 70 dias de confinamento. Foram realizadas hemogasometria, concentração sérica de ureia e creatinina e avaliação ultrassonográfica do trato urinário. Na urinálise, houve uma maior incidência de cristais de fosfato amônio magnesiano no início do estudo, com migração para formação de cristais de urato, principalmente no G500, devido à acidificação urinária. Não houve alterações hemogasométricas, na bioquímica sérica, no líquido ruminal, ou alterações ultrassonográficas. A acidificação urinária foi obtida e mantida a partir do M7 durante a administração do cloreto de amônio no grupo G500, não ocorrendo nos outros grupos de estudo.(AU)

ABSTRACT

Objetivou-se no presente estudo comparar as técnicas de coleta de urina via sondagem uretral e cistocentese guiada por ultrassom, afim de verificar se o método de coleta pode influir nos resultados laboratoriais. Foram utilizados 12 cães machos, sem histórico de enfermidades, dos quais coletou-se cinco mililitros (mL) de urina via sondagem uretral e cinco mL via cistocentese guiada por ultrassom, ambas no mesmo momento. Posteriormente foi realizada a análise física (cor, odor, densidade, turbidez), química (urobilinogênio, glicose, corpos cetônicos, bilirrubina, proteína, nitrito, pH, sangue e leucócitos) e sedimentoscopia (avaliação de 10 campos de luz, objetiva de 40x). Cilindros urinários, cristais, corpúsculos gordurosos, espermatozoides, bactérias e células vesicais foram classificados qualitativamente como: ausentes (0), discretos (1), moderados (2) e intensos (3). Hemácias, leucócitos, e células de descamação foram quantificadas a partir da média dos campos analisados. As análises bioquímicas de microalbuminúria, creatinina e proteína total urinárias foram realizadas a partir do sobrenadante urinário, removido das amostras após centrifugação, e utilizados kits reagentes, conforme recomendação do fabricante, sendo a leitura em espectrofotômetro. Em todos os testes realizados os valores de p encontrados foram superiores 0,05 (p>0,05), excluindo-se a possibilidade de haver diferenças significativas dos resultados laboratoriais obtidos pelas duas formas de coleta.


The objective of this study was to compare two techniques of urine collection, urethral catheterization and ultrasound-guided cystocentesis, in order to verify if the collection method may influence the laboratory results. Twelve male dogs were used, with no history of diseases, of which five milliliters (mL) of urine were collected by urethral catheterization and five mL by both at the same time. Subsequently, the samples underwent physical analysis (color, smell, density andturbidity), chemical analysis (urobilinogen, glucose, ketone bodies, bilirubin, protein, nitrite, pH, blood and leukocytes) and sedimentoscopy (evaluation of 10 light fields, 40x objective). Urinary casts, fatty corpuscles, spermatozoa, bacteria and bladder epithelial cells were classified qualitatively as absent (0), discrete (1), moderate (2) and intense (3). Red blood cells, leukocytes and desquamation cells were quantified from the mean of the analyzed fields. The urine supernatants were obtained after centrifugation and were used for biochemical analyzes of microalbuminuria, urinary protein and creatinine. The reagent kits were used as recommended by the manufacturer and the samples were read by spectrophotometry. All tests presented p values higher than 0,05 (p>0,05), excluding the possibility of significant differences between the laboratory results of both forms of urine collection.

ABSTRACT

Objetivou-se verificar a compatibilidade entre diferentes marcas de tiras reagentes para urinálise, tanto de uso veterinário, como de uso humano, e confrontar os parâmetros semiquantitativos desse instrumento com métodos quantitativos. Para isso, foram analisadas 77 amostras frescas de urina de cães e gatos e testados 04 modelos de tiras reagentes. Quanto à densidade urinária, houve correlação razoável entre os métodos quantitativo e semiquantitativo naquelas amostras com pH ácido, mas não naquelas com pH neutro ou alcalino. Quanto à concentração proteica, houve similaridade de 53,3% a 83,3% entre as marcas testadas e quando comparadas com a análise fotométrica houve uma correlação razoável (rs = 0,69752 a 0,75074). Em ponto de corte de 15mg/dL de proteína, a sensibilidade da tira reagente foi 82,5% e 100% para urina canina e felina, respectivamente. No tocante à hematúria, houve divergência razoável entre a sedimentoscopia e as diferentes marcas de tiras reativas. Quanto à piúria, há uma baixa sensibilidade das tiras em relação às amostras caninas com muitos resultados falso-negativos (33% a 75%), enquanto em amostras felinas a sensibilidade foi de 100%. Assim, independente da marca, as tiras reagentes devem servir apenas como teste rápido de triagem, sendo mais apropriado o uso de métodos quantitativos na avaliação clínica do paciente a partir da urinálise.


The aim was to verify the compatibility between different brands of urinary dipsticks, for both human and veterinary use, and to compare the semiquantitative parameters of this instrument with quantitative methods. For this, 77 fresh samples of urine from dogs and cats were analyzed e and 04 models of reagent strips were tested. Regarding urinary density, a reasonable correlation was observed between the quantitative and semiquantitative methods in those samples with acidic pH, which did not occur in those with neutral or alkaline pH. Regarding the protein concentration, there was similarity from 53.3% to 83.3% between the brands and in the comparative analysis between the control strip and the photometric analysis, there was a reasonable correlation (rs = 0.69752 to 0.75074). In cut-off point of 15mg/dL protein, the sensitivity of the reagent strip was 82.5% and 100% for canine and feline urine, respectively. Regarding hematuria, there was a reasonable divergence of results between sedimentation and tested dipsticks. As for pyuria, there is a low sensitivity of the strips in relation to canine samples with many false negative results (33% to 75%), while in feline samples the sensitivity was 100%. Thus, regardless of the brands, the reagent strips should serve only as a rapid screening test, while the use of quantitative methods in the clinical evaluation of the patient from urinalysis is more appropriate.

ABSTRACT

ABSTRACT Introduction Dehydration has been described as one of the main factors of reduced performance in combat sports activities, leading to death in extreme cases. Objective To investigate the pre-training hydration status and changes in fluid homeostasis during two taekwondo training sessions. Methods Eighteen male college athletes (age 22.6 ± 3.37 years) were assessed. The study design aimed to reproduce the conditions of a 90-minute taekwondo training session, divided into three stages: a) warm-up exercises (20 min); b) poomsae (30 min) and c) technical training (40 min). The athletes had ad libitum water intake during training. To assess the hydration status we considered body mass (BM), the amount of liquid consumed and urine output, which enabled us to establish absolute and relative fluid loss in kg and percentage as well as the sweating rate. We also considered urine specific gravity (USG), urine color (U-COL), and subjective sensation of thirst (Sthirst) before and after the training session. Pre- and post-training results were compared separately in each session and between sessions. Results There was a significant difference (P<0.05) in pre-training BM between the two days of training. There was a significant difference (P<0.05) in the final BM on both days of the experiment. Most subjects had relative dehydration below 2%. A significant difference (P<0.05) was recorded pre and post training for U-COL and Sthirst, with the highest rates obtained at the end of each session. Participants always started training at a low dehydration status (USG >1,020g.ml-1). Conclusions The athletes tended to start the training sessions in dehydration status, which increases over the course of the training. Ad libitum water intake was not sufficient to balance fluid loss. Changes in fluid levels between sessions were similar.

RESUMO Introdução A desidratação tem sido descrita como um dos principais fatores de redução de desempenho em atividades de luta, levando, em casos extremos, à morte. Objetivos Investigar o estado da hidratação antes do treino e as alterações no balanço hídrico corporal durante dois treinamentos de taekwondo. Métodos Foram avaliados 18 atletas universitários do sexo masculino (22,6 ± 3,37 anos). O desenho do estudo procurou reproduzir uma condição de treinamento de taekwondo com duração de 90 minutos, dividido em três etapas: a) aquecimento (20 min.), b) poomsae (30 min.) e c) treino técnico (40 min.). Durante o treino, adotou-se o consumo de água ad libitum. Para avaliar o estado de hidratação, considerou-se a massa corporal (MC), a quantidade de líquido consumido e o volume de urina produzido, o que permitiu estabelecer a perda hídrica absoluta e relativa em kg e porcentagem, além da taxa de sudorese. Foi considerada ainda a gravidade específica da urina (GEU), bem como sua coloração (COL-U), além da sensação subjetiva de sede (SSede) antes e depois do treino. Os resultados antes e depois do treino foram comparados de forma isolada em cada sessão, assim como entre as sessões. Resultados Houve diferença significativa (P < 0,05) da MC pré-treinamento entre os dois dias de treino. Houve redução significativa (P < 0,05) da MC final em ambos os dias de experimento. A maior parte dos avaliados apresentou desidratação relativa inferior a 2%. Registrou-se diferença significativa (P < 0,05) antes e depois do treino para COL-U e para SSede, com os maiores índices obtidos ao final de cada sessão. Os participantes sempre iniciaram o comparados de forma isolada em cada sessão, assim como entre as sessões. Resultados Houve diferença significativa (P < 0,05) da MC pré-treinamento entre os dois dias de treino. Houve redução significativa (P < 0,05) da MC final em ambos os dias de experimento. A maior parte dos avaliados apresentou desidratação relativa inferior a 2%. Registrou-se diferença significativa (P < 0,05) antes e depois do treino para COL-U e para SSede, com os maiores índices obtidos ao final de cada sessão. Os participantes sempre iniciaram o treinamento em leve estado de desidratação (GEU > 1.020 g.ml-1). Conclusões Os atletas tendem a iniciar os treinamentos em estado de desidratação, que se amplia durante o treino. O consumo de líquidos ad libitum não foi suficiente para equilibrar a perda hídrica. As alterações hídricas entre as sessões foram semelhantes. Nível de Evidência II; Estudos terapêuticos- Investigação dos resultados do tratamento.

ABSTRACT

The abundance of proteins in human urine is low and easily to be masked by high-abundance proteins during mass spectrometry analysis. Development of efficient and highly selective enrichment methods is therefore a prerequisite for achieving deep coverage of urine protein markers. Notably, different experimental methods would affect the urine protein enrichment efficacy and the coverage of urine proteome. In this study, ultrafiltration, nitrocellulose membrane enrichment and saturated ammonium sulfate precipitation were used to process 10 mL urine samples from five healthy volunteers and five bladder cancer patients. The urine proteins were enriched and separate by SDS-PAGE to compare the purification efficiency of different methods. Moreover, the peptide identification effects of different purification methods were analyzed by mass spectrometry to determine the best method for enriching urine protein histones. Saturated ammonium sulfate precipitation method outperformed the ultrafiltration and the nitrocellulose membrane enrichment methods in terms of the protein enrichment efficacy and quality. The interference of highly abundant albumin was reduced, whereas the amount of low-abundance protein was increased, and the sensitivity of mass spectrometry identification was increased. The saturated ammonium sulfate precipitation method may be applied for large-scale urine processing for screening clinical diagnostic markers through proteomics.

ABSTRACT

A diabetes mellitus (DM) é uma doença comum na rotina veterinária, de caráter multifatorial, gerando graves consequências na saúde dos pacientes acometidos. O diagnóstico é possível por meio de manifestações clínicas apresentadas e da realização de exames laboratoriais complementares. Entre esses exames, estão a dosagem da glicose sérica e a urinálise, as quais trazem ao clínico diversas informações, que podem ser correlacionadas aos demais achados, tornando possível o diagnóstico conclusivo de DM. Dessa forma, o presente trabalho teve como objetivo avaliar as alterações urinárias e de glicemia em cães com DM. Para isto, foram analisados laudos de amostras urinárias e de glicose sérica de 15 animais, onde o diagnóstico foi conclusivo para DM. Verificou-se presença de glicosúria em 100% dos casos, sendo observado em 66,67% das amostras glicosúria maior que 1000 mg/dL e, em 33,33% amostras, de 500 mg/dL; a cetonúria esteve presente em 66,67 %; proteinúria em 66,67% e bacteriúria presente em 73,33 dos dados analisados. Já a hiperglicemia foi constatada em 13 pacientes (86,67%). Assim, conclui-se que a urinálise é um exame de suma importância para o estabelecimento do diagnóstico, da melhor terapêutica para cada caso e do prognóstico dos pacientes.(AU)


Diabetes mellitus (DM) is a common disease on the veterinary routine. It has a multifactorial character generating severe consequences on the health of the patient. It can be diagnosed by clinical manifestations and by making additional laboratory tests. These tests include the measurement of serum glucose and urinalysis, which provides the physician with additional information to be correlated with other findings, in order to reach a conclusive diagnosis of DM. Therefore, this study aimed at evaluating urinary and glycemic alterations in dogs with DM. It analyzed reports of urine and serum glucose samples from 15 animals with a conclusive diagnosis for DM. Glycosuria was present in 100% of the cases. In addition, it was also observed that in 66.67% of the samples, glycosuria was higher than 1000 mg/dL, and in 33.33%, it was 500 mg/dL. Ketonuria was present in 66.67% of the samples, while proteinuria was observed in 66.67%. Bacteriuria was present in 73.33% of the samples on the analyzed data. Hyperglycemia was observed in 13 of these patients (86.67%), and thus, it can be concluded that urinalysis is an extremely important test for diagnosis, to choose the best therapy for each case and prognosis of the patients.(AU)

ABSTRACT

Apesar de inicialmente terem surgido como agentes etiológicos de resfriados comuns, os coronavírus se tornaram uma ameaça global no século XXI, provocando síndromes respiratórias com alto poder de transmissão e contribuindo para quadros graves que podem levar à morte. Além dos coronavírus que emergiram no século XXI, quatro outros coronavírus humanos são mundialmente endêmicos e atualmente representam até 30% das infecções do trato respiratório superior em adultos. A pandemia atual de Síndrome Respiratória Aguda Grave causada por SARS-CoV-2, denominada COVID-19, vem aumentando sua casuística de forma importante, causando o colapso dos sistemas de saúde. Além dos danos ao sistema respiratório, a insuficiência renal aguda (IRA) é uma importante complicação da COVID-19, ocorrendo em 0,5%-7% dos casos e em 2,9%-23% dos pacientes em Unidade de Terapia Intensiva (UTI). Até o momento não se conhecem os mecanismos relacionados à etiologia da IRA associada à COVID-19. Nesta revisão são apresentadas algumas informações associadas à COVID-19 como histórico, manifestações clínicas e laboratoriais, à IRA (especialmente em pacientes internados em UTI) e enfatizando as alterações evidenciadas no exame de urina em pacientes com COVID-19.


Although they initially emerged as etiologic agents of common colds, coronaviruses became a global threat in the 21st century, causing respiratory syndromes with high transmission power and contributing to serious conditions that can lead to death. In addition to the coronaviruses that emerged in the 21st century, four other human coronaviruses are globally endemic and currently account for up to 30% of upper respiratory tract infections in adults. The current pandemic of Severe Acute Respiratory Syndrome caused by SARS-CoV-2, called COVID-19, has been increasing its casuistry significantly, and causing the collapse of health systems. In addition to damage to the respiratory system, acute kidney injury (AKI) is an important complication of COVID-19, occurring in 0.5-7% of cases and in 2.9-23% of patients in the Intensive Care Unit (ICU). So far, the mechanisms related to the etiology of AKI associated with COVID-19 are not known. In this review, some information associated with COVID-19 is presented, such as history, clinical and laboratory manifestations, AKI (especially in ICU patients), and emphasizing the changes evidenced in the urine test in patients with COVID-19.

ABSTRACT

BACKGROUND: Taraxacum species (commonly known as dandelion) used as herbal medicine have been reported to exhibit an antiproliferative effect on hepatoma cells and antitumor activity in non-small-cell lung cancer cells. Although several investigations have demonstrated the safety of Taraxacum officinale, the safety of tissue-cultured plants of T. formosanum has not been assessed so far. Therefore, the present study examines the safety of the water extract of the entire plant of tissue cultured T. formosanum based on acute and subacute toxicity tests in rats, as well as the Ames tests. RESULTS: No death or toxicity symptoms were observed in the acute and subacute tests. The results of the acute test revealed that the LD50 (50% of lethal dose) value of the T. formosanum water extract for rats exceeded 5 g/kg bw. No abnormal changes in the body weight, weekly food consumption, organ weight, or hematological, biochemical, and morphological parameters were observed in the subacute toxicity test. Thus, the no observed adverse effect level (NOAEL) of T. formosanum water extract was estimated to be higher than 2.0 g/kg. Finally, the results of the Ames test revealed that T. formosanum water extract was not genotoxic at any tested concentration to any of five Salmonella strains. CONCLUSIONS: The water extract of tissue-cultured T. formosanum was non-toxic to rats in acute and subacute tests and exhibited no genotoxicity to five Salmonella strains.

ABSTRACT

Objetivo: As infecções urinárias (ITU) acometem indivíduos no mundo inteiro e são causadas principalmente por bactérias Gram-negativas, sendo o diagnóstico laboratorial realizado pelo EAS e urocultura. Nesse estudo foram pesquisadas, em amostras de uroculturas positivas, as alterações apresentadas no exame de EAS, principalmente os marcadores de leucócitos e nitrito, e se estes poderiam contribuir para o diagnóstico da ITU. Também foram pesquisadas a faixa etária e a bactéria mais prevalente. Métodos: Um estudo retrospectivo foi realizado com base no levantamento de dados dos exames de urocultura realizados no Laboratório Clínico da PUC Goiás (LAC/PUC Goiás), no período de janeiro/2017 a agosto/2018, de acordo com idade, gênero do paciente e a espécie bacteriana isolada. Resultados: De 629 uroculturas positivas foi encontrada prevalência de ITU em adultos (63,3%), com predomínio no sexo feminino (85,8%), sendo a Escherichia coli (58,9%) a bactéria mais isolada. O nitrito foi detectado em 36,9% e a leucocitúria em 60,6% das amostras. Conclusão: Os resultados evidenciaram predomínio de ITU em adultos do sexo feminino, sendo a Escherichia coli a bactéria com maior prevalência. Quanto aos resultados do EAS, a leucocitúria revelou-se um marcador mais sensível para auxílio diagnóstico de ITU em relação ao nitrito, corroborando com a literatura científica especializada.


Objective: Urinary tract infections (UTI) affect individuals worldwide and are mainly caused by Gram-negative bacteria, and the laboratory diagnosis is performed by urinalysis and uroculture. In this study were investigated in samples of positive urocultures, the alterations presented in the examination of urinalysis, mainly leukocytes and nitrite, and if could contribute to the diagnosis of UTI. The most prevalent age group and bacteria were also investigated. Methods: A retrospective study was carried out based on data collection of uroculture examinations performed at the Clinical Laboratory of PUC Goiás (LAC/PUC Goiás), from january/2017 to august/2018, according to age, gender of patient and the isolated bacterial species. Results: Of 629 positive urocultures, the prevalence of UTI was found in adults (63,3%), with predominance in females (85,8%), and Escherichia coli (58,9%) was the most isolated bacteria. Nitrite was detected in 36,9% and leukocyturia in 60,6% of the samples. Conclusion: The results evidenced a predominance of UTI in female adults, and Escherichia coli was the most prevalent bacteria. Regarding the results of the urinalysis, leukocyturia proved to be a more sensitive marker for the diagnosis aid of UTI in relation to nitrite, corroborating with the literature.

ABSTRACT

BACKGROUND: Pyuria seems to be common in chronic kidney disease (CKD), irrespective of urinary tract infection (UTI). It has been hypothesized that sterile pyuria occurs in CKD because of chronic renal parenchymal inflammation. However, there are limited data on whether CKD increases the rate of pyuria or how pyuria in CKD should be interpreted. We investigated the prevalence and characteristics of asymptomatic pyuria (ASP) in CKD via urinary white blood cell (WBC) analysis.METHODS: Urine examination was performed for all stable hemodialysis (HD) and non-dialysis CKD patients of the outpatient clinic (total N=298). Patients with infection symptoms or recent history of antibiotic use were excluded. Urine culture and WBC analysis were performed when urinalysis revealed pyuria.RESULTS: The prevalence of ASP was 30.5% (24.1% in non-dialysis CKD and 51.4% in HD patients). Over 70% of the pyuria cases were sterile. The majority of urinary WBCs were neutrophils, even in sterile pyuria. However, the percentage of neutrophils was significantly lower in sterile pyuria. In multivariate logistic regression analysis, the degree of pyuria, percentage of neutrophils, and presence of urinary nitrites remained independently associated with sterile pyuria.CONCLUSIONS: The prevalence of ASP was higher in CKD patients and increased according to CKD stage. Most ASP in CKD was sterile. Ascertaining the number and distribution of urinary WBCs may be helpful for interpreting ASP in CKD.

ABSTRACT

RESUMEN Objetivo: determinar la prevalencia de infección del tracto urinario (ITU), el perfil microbiológico y la resistencia a los antibióticos en mujeres gestantes con sospecha de infección del tracto urinario. Materiales y métodos: estudio de corte transversal. Ingresaron gestantes con sospecha de infección del tracto urinario adquirida en la comunidad, remitidas a consulta externa desde su control prenatal o atención por urgencias, y hospitalizadas entre agosto de 2013 y septiembre de 2015 en un hospital universitario de referencia ubicado en Medellín, Colombia. Se excluyeron gestantes que hubieran recibido antibióticos el día anterior a la admisión. Muestreo aleatorio simple. Variables medidas: sociodemográficas, clínicas y bacteriológicos. Se aplicó estadística descriptiva. Resultados: la prevalencia de infección del tracto urinario fue del 29 %. Predominaron los aislamientos de bacterias Gram negativas, principalmente E. coli y K. pneumoniae en un 57,7 y 11,4 % respectivamente. Se observó resistencia a trimetoprim-sulfametoxazol en el 19,5 % y ampicilina-sulbactam en el 17,5 % de los aislamientos. Conclusiones: se requieren estudios de base poblacional para una mejor aproximación a la resistencia de las bacterias causantes de la ITU en la comunidad. Por otra parte, la alta resistencia observada podría sugerir que algunos antibióticos expuestos no sean incluidos en las guías locales de manejo de la ITU.


ABSTRACT Objective: To determine the prevalence of urinary tract infections (UTIs), the microbiological profile and antibiotic resistance in pregnant women with suspected urinary tract infection. Materials and methods: Cross-sectional study of pregnant women with suspected community- acquired urinary tract infection referred to the outpatient clinic by prenatal care practitioners or seen in the emergency room, and hospitalized between August 2013 and September 2015 in a referral teaching hospital located in Medellin, Colombia. Pregnant women who had received antibiotics on the day before admission were excluded. Random sampling. Measured variables: sociodemographic, clinical and bacteriological. Descriptive statistics were applied. Results: The prevalence of urinary tract infections was 29%. Gram negative bacteria isolates were found predominantly, the main ones being E. coli and K. pneumoniae at 57.7 and 11.4%, respectively. Resistance to trimethoprim- sulfamethoxazole and to ampicillin-sulbactam was observed in 19.5% and 17.5% of isolates, respectively. Conclusions: Population-based studies are needed to provide a better approach to bacterial resistance in community-acquired UTIs. On the other hand, the high resistance observed may suggest that some of the exposed antibiotics might not be included in the local guidelines for the management of UTIs.

ABSTRACT

ABSTRACT Objectives To primarily evaluate the functional outcomes of PCNL for bilateral renal calculi/calculi in solitary functioning kidney with Chronic Kidney Disease(CKD). To identify factors affecting the renal replacement therapy following PCNL. Materials and Methods Patients with bilateral renal calculi/calculi in solitary kidney and CKD (eGFR<60/s.creatinine>2) and Good Performance Status [Eastern Cooperative Oncology Group (ECOG): 0-2] were included in the study. Results A total of 60 patients with CKD who had bilateral renal calculi/calculi in solitary functioning kidney underwent PCNL. At 6 months, eGFR improved or stabilized in 45 (75%) patients, while in 15 (25%) patients eGFR deteriorated. A total of 5 (14.28%) and 2 (25%) patients of CKD stage 4 and 5 respectively had improvement in eGFR as well as CKD stage. Fourteen (82.35%), 21 (60%), 3 (37.5%) patients of CKD stage 3, 4, 5 had improvement in eGFR but not significant enough to cause stage migration. Again 3 (17.65%) , 9 ( 40%) and 3 (37.5%) patients of CKD stage 3, 4, 5 had reduction in eGFR but not significant enough to cause stage migration. None of the patients had worsening of CKD stage. Preoperative CKD stage and eGFR were compared with measurements made at the final follow up visit (6 months). Conclusion Our results indicate that most patients of renal calculi with CKD show improvement or stabilization of renal function with aggressive stone removal. Improvement is more in patients who have mild to moderate CKD. Aggressive management of comorbidities, peri-operative UTI and complications may delay or avoid progression of CKD status in such patients.

ABSTRACT

Objetivo: A sedimentoscopia apresenta atividade manual acentuada, pouca uniformidade e maiores custos aos laboratórios. Em diversos países é utilizado o emprego seletivo da sedimentoscopia em amostras de rotina de urina com normalidade nas etapas físico-químicas, no Brasil não ocorre uma abordagem nesse modelo. Assim, é importante avaliar a aplicabilidade do emprego seletivo da sedimentoscopia tendo em vista o custo-benefício na análise da rotina de urina. Métodos: Foi realizado um estudo analítico descritivo através de resultados de exames de urina de indivíduos do município de Paulo Afonso ­ BA. Para análise estatística foi utilizado o teste de qui-quadrado e o valor de p<0,05 foi considerado estatisticamente significativo. Resultados: A partir dos resultados referentes aos 2.607 exames de urina de rotina analisados, foi observado que 66% das mostras não apresentaram alterações físico-químicas. Destas amostras com análise físico-química sem alterações, 12,89% compreenderam alteração na análise sedimentoscópica e, dentre os elementos analisados, a presença de piócitos foi a anormalidade que apresentou maior incidência. O valor preditivo negativo referente aos elementos encontrados na sedimentoscopia de urina com análise físico-química sem alterações foi de 86%. Conclusão: Apesar do considerável valor preditivo negativo, o valor de alterações encontradas em urinas com análise físico-química normal é relevante e expõe a necessidade da realização dessa etapa no exame de rotina de urina. A utilização seletiva da sedimentoscopia deve ser adotada de maneira crítica, pois é necessária uma avaliação minuciosa dos riscos relacionados à saúde do paciente e à qualidade do exame.


Objective: Sediment microscopy is a markedly manual activity, with poor uniformity and high labor costs. In several countries, the selective use of sediment microscopy for routine urine samples with normal physicochemical results is used, in Brazil, an approach in this model does not occur. It is therefore important to evaluate the applicability of a selective use of sediment microscopy in Brazil, taken from the view of cost-benefit analysis. Methods: A descriptive analytical study was carried out using results of urine exams from individuals in the city of Paulo Afonso/BA. The chi-square test was used for analysis and the value of p <0.05 was considered statistically significant. Results: From the results of the 2607 routine urine tests analyzed, 1722 samples presented no physicochemical alterations. Of these samples with physicochemical analysis without alterations, 12.89% presented alterations during sediment analysis and among the elements analyzed the presence of pyocytes was the abnormality that presented higher incidence. The negative predictive value for the urine elements found during sediment microscopy of the normal physicochemical analyses was 86%. Conclusion: Despite the considerable negative predictive value, the value of alterations found in urines with normal physicochemical analysis is relevant and exposes the need to perform this step in the routine urinalysis. Since a thorough evaluation of the risks linked to the patient's health and quality examination

ABSTRACT

Objetivo: O objetivo foi avaliar a concordância entre o método de sedimentoscopia proposto pela Associação Brasileira de Normas Técnicas e o método proposto pela Sociedade Brasileira de Patologia Clínica/Medicina Laboratorial. Métodos: A partir da urina de nove indivíduos, foram obtidas 72 amostras analisadas por ambos os métodos. Cada amostra foi examinada por quatro avaliadores. A concordância entre os métodos foi medida através do coeficiente de correlação de Pearson (r) para as variáveis contínuas e o coeficiente de concordância kappa (k) para as categóricas. Resultados: Houve concordância entre os métodos para a quantificação de cilindros leucocitários (97,2%, k = 0,61, p<0,01), e presença de cristais de oxalato de cálcio (77,8%, k = 0,43, p=0,04), cilindros hialinos (88,9%, k = 0,51, p=0,04), sais de uratos amorfos (83,3%, k = 0,59, p=0,03), fios mucosos (83,3%, k = 0,48, p=0,04) e leveduras (75,9%, k = 0,54, p=0,04). Os métodos tiveram correlação moderada quanto ao número de hemácias (r = 0,56, p=0,04) e células epiteliais (r = 0,73, p=0,04). Destaca-se um maior tempo de processamento e leitura da amostra para o método proposto pela SBPC/ML (23,4 min) quando comparado com o da ABNT NBR 15268 (16,6 min, p<0,01). Conclusão: Embora os métodos propostos tenham apresentado concordância entre muitos dos parâmetros avaliados, os principais achados associados a processos infecciosos e inflamatórios como bacteriúria e leucocitúria, comuns no exame de urina, precisam ser mais bem investigados. Além disso, é importante que, de acordo com a metodologia empregada, o tempo de processamento e a logística técnica/laboratorial sejam adequados.


Objective: Evaluate the conformity between sediment method suggested by Brazilian Association of Technical Norms and another method suggest by Brazilian Society of Clinical Pathology Laboratory Medicine. Methods: It was used urine from nine people, obtaining 72 samples analyzed by both methods. Four different researchers examined each sample. The conformity between these methods was measured by the Pearson correlation coefficient for continuous variables and kappa concordance coefficient for the category variables. Results: There was concordance between methods for quantification of leukocyte casts (97.2%, κ = 0.61, p < 0.01), calcium oxalate crystals presence (77.8%, κ = 0.43, p = 0.04), hyaline casts (88.9%, κ = 0.51, p = 0.04), amorphous urate crystals (83.3%, κ = 0.59, p = 0.03), mucus (83.3%, κ = 0.48, p = 0.04) and yeast (75.9%, κ = 0.54, p = 0.04). These methods had moderate correlation for erythrocytes number (r = 0.56, p = 0.04) and epithelial cells (r = 0.73, p = 0.04). It is still worth noting SBPC/ML method requests a larger processing time (23.4 minutes) when compared to ABNT NBR 15268 (16.6 minutes, p < 0.01). Conclusion: Although the proposed methods had presented conformity at the evaluate parameters, the most important results associated to infection and inflammatory processessuch as bacteriuria and leukocyturia, common at urine exams, need to b e more studied. Thus, it is important that, according to the used methodology, the processing time and technical/laboratory logistic needs to be adequate

ABSTRACT

Kidney disease that affects bitches with pyometra may lead patients to develop chronic renal failure even after pyometra treatment. Therefore, several studies have sought to clarify the gaps in the understanding of the pathogenesis of renal injury in pyometra. Identification of early detection markers for renal damage, which can predict and identify the prognosis of the disease, is very important. Proteinuria analysis can diagnose kidney damage, since proteins such as albumin are not filtered through the glomerulus and those that undergo glomerular filtration are almost completely reabsorbed by tubular cells. The objective of this study was to evaluate whether the urinary protein-to-creatinine ratio (UPC) can detect renal injury in bitches with pyometra before development of azotemia. For this, 44 bitches with pyometra were divided into two groups: bitches with azotemic piometra (A, n=15, creatinine >1.7) and bitches with non-azotemic pyometra (NA, n=29). The two groups were compared to the control group (CG, n=12), which had no signs of systemic disease. All animals underwent blood and urine tests. Leukocytosis was more evident in bitches in the A group than in the other groups. This shows that the inflammatory response may be associated with the pathogenesis of renal injury. The median UPC in bitches with pyometra was significantly higher than in the CG, with a median above the reference values. In conclusion, the UPC can be used in bitches with pyometra to detect renal damage before the development of azotemia. It has been suggested that the UPC of bitches with pyometra should be followed through during the postoperative period so that permanent renal lesions secondary to pyometra can be diagnosed and treated properly before the development of azotemia.(AU)


A doença renal que afeta cadelas com piometra pode levar a insuficiência renal crônica mesmo após o tratamento. Portanto, vários estudos procuraram esclarecer as lacunas na compreensão da patogênese da lesão renal na piometra. A identificação de marcadores de lesão renal precoce, que podem prever e identificar o prognóstico da doença é muito importante. A análise da proteinúria pode diagnosticar lesão renal, uma vez que proteínas como a albumina não são filtradas através do glomérulo e aquelas que sofrem filtração glomerular são quase completamente reabsorvidas pelas células tubulares. O objetivo deste estudo foi avaliar se a relação proteína-creatinina urinária (UPC) pode detectar lesão renal em cadelas com piometra antes do desenvolvimento de azotemia. Para isso, 44 cadelas com piometra foram divididas em dois grupos: cadelas com piometra azotêmica (A, n=15, creatinina >1,7) e cadelas com piometra não azotêmica (NA, n=29). Os dois grupos foram comparados ao grupo controle (CG, n=12), que não apresentaram sinais de doença sistêmica. Todos os animais foram submetidos a exames de sangue e urina. A leucocitose foi mais evidente nas cadelas do grupo A do que nos outros grupos. Isso mostra que a resposta inflamatória pode estar associada à patogênese da lesão renal. A mediana da UPC em cadelas com piometra foi significativamente maior que no CG, com uma mediana acima dos valores de referência. Em conclusão, a UPC pode ser usada em cadelas com piometra para detectar lesões renais antes do desenvolvimento de azotemia. Sugeriu-se que a UPC de cadelas com piometra deve ser acompanhada durante o pós-operatório, de modo que as lesões renais permanentes secundárias à piometra possam ser diagnosticadas e tratadas adequadamente antes do desenvolvimento de azotemia.(AU)

ABSTRACT

BACKGROUND: Yersinia pseudotuberculosis is known to cause fever, gastroenteritis, or acute kidney injury (AKI). There have been several Y. pseudotuberculosis infection outbreaks to date associated with ingestion of contaminated food or unsterile water. While this disease was considered to have practically been eradicated with the improvement in public health, we encountered several cases of AKI associated with Yersinia infection. METHODS: We retrospectively collected data from medical records of patients with suspected Y. pseudotuberculosis infection who visited Seoul National University Children’s Hospital in 2017. RESULTS: There were nine suspected cases of Yersinia infection (six males and three females; age range 2.99–12.18 years). Among them, five cases occurred in May, and seven patients were residing in the metropolitan Seoul area. Three patients had history of drinking mountain water. Every patient first presented with fever for a median of 13 days, followed by gastrointestinal symptoms and oliguria. Imaging studies revealed mesenteric lymphadenitis, terminal ileum wall thickening, and increased renal parenchymal echogenicity. Creatinine levels increased to 5.72 ± 2.18 mg/dL. Urinalysis revealed sterile pyuria, proteinuria, and glycosuria. Oliguria continued for 4 to 17 days, and two patients required dialysis; however, all of them recovered from AKI. Mucocutaneous manifestations developed later. In the diagnostic work-up, Yersinia was isolated from the stool culture in one patient. Anti-Yersinia immunoglobulin (Ig) A and IgG were positive in 6 patients. CONCLUSION: Y. pseudotuberculosis infection is an infrequent cause of interstitial nephritis presenting with AKI. When a patient presents with fever, gastroenteritis, and AKI not resolving despite hydration, the clinician should suspect Y. pseudotuberculosis infection.
