Resumo As arboviroses são endêmicas em vários países e representam um preocupante problema de saúde pública. A mais importante delas é a dengue, que teve um aumento progressivo do número de casos, atingindo a marca dos milhões de casos anuais no Brasil desde a última década. Outras arboviroses de importância para a saúde pública incluem a chikungunya e a Zika, ambas causas de epidemias recentes, e a Febre Amarela, que também tem causado surtos epidêmicos em nosso país. Assim como a maioria das doenças infecciosas, as arboviroses têm o potencial de acometer os rins, por meio de diversos mecanismos que levam à injúria renal, incluindo ação direta dos vírus, inflamação sistêmica, fenômenos hemorrágicos e outras complicações, além da toxicidade de drogas utilizadas no tratamento. Neste artigo de revisão, serão abordados os aspectos epidemiológicos das principais arboviroses no Brasil e em outros países onde estas doenças são endêmicas, os aspectos clínicos e as principais alterações laboratoriais encontradas, incluindo as alterações na função renal. Como as arboviroses se comportam nos pacientes transplantados renais também será descrito. Serão também descritos os mecanismos fisiopatológicos da injúria renal associada às arboviroses e, por fim, o tratamento recomendado para cada doença e as recomendações para o suporte renal neste contexto. dengue década Zika recentes Amarela país infecciosas rins vírus sistêmica complicações revisão encontradas descrito fim contexto

Abstract Arboviruses are endemic in several countries and represent a worrying public health problem. The most important of these diseases is dengue fever, whose numbers continue to rise and have reached millions of annual cases in Brazil since the last decade. Other arboviruses of public health concern are chikungunya and Zika, both of which have caused recent epidemics, and yellow fever, which has also caused epidemic outbreaks in our country. Like most infectious diseases, arboviruses have the potential to affect the kidneys through several mechanisms. These include the direct action of the viruses, systemic inflammation, hemorrhagic phenomena and other complications, in addition to the toxicity of the drugs used in treatment. In this review article, the epidemiological aspects of the main arboviruses in Brazil and other countries where these diseases are endemic, clinical aspects and the main laboratory changes found, including changes in renal function, are addressed. It also describes how arboviruses behave in kidney transplant patients. The pathophysiological mechanisms of kidney injury associated with arboviruses are described and finally the recommended treatment for each disease and recommendations for kidney support in this context are given. problem fever decade Zika epidemics country viruses inflammation complications article found function addressed patients given

SUMMARY OBJECTIVE: The objective was to analyze the implementation and use of the electronic patient record in the health services of the Brazilian Air Force. METHODS: This is a cross-sectional study carried out with 234 physicians, between March and May 2021. The data collection instrument was sent by email. The electronic patient record was implemented in the Air Force approximately 3 years ago (64.5%), and about 81% of the physicians received training to operate it. RESULTS: The most common records involve data related to consultations (90.1%) and interviews with physical examination (67.1%). Physicians cited that information storage (75.6%), agility, and feasibility of recording (55.1%) were the main advantages of the electronic patient record. As disadvantages, problems in electronic equipment (69.7%) and system errors (65%) were reported. Most participants considered that the implementation had a positive impact on work dynamics (75.6%) and productivity (66.7%), mainly regarding the components "Work processes" (57.3%) and "Amount of carried out activities" (21.4%). Keeping records was significantly associated with the job position (p<0.001), type of unit (p=0.008), time of implementation (p<0.001), and participation in training (p=0.028). CONCLUSION: The implementation of the electronic patient record in the Air Force was recently done, and just over half of the physicians were trained prior to the implementation. The tool is considered compatible with work processes and has a positive effect on productivity.

ABSTRACT Objective: To assess whether the use of ELMO, a helmet for noninvasive ventilation created in Brazil, had a positive impact on the prognosis of patients with hypoxemic respiratory failure caused by severe COVID-19. Methods: This is a retrospective study of 50 critically ill COVID-19 patients. Epidemiological, clinical, and laboratory data were collected on ICU admission, as well as before, during, and after ELMO use. Patients were divided into two groups (success and failure) according to the outcome. Results: ELMO use improved oxygenation parameters such as Pao2, Fio2, and the Pao2/Fio2 ratio, and this contributed to a gradual reduction in Fio2, without an increase in CO2, as determined by arterial blood gas analysis. Patients in the success group had significantly longer survival (p < 0.001), as determined by the Kaplan-Meier analysis, less need for intubation (p < 0.001), fewer days of hospitalization, and a lower incidence of acute kidney injury in comparison with those in the failure group. Conclusions: The significant improvement in oxygenation parameters, the longer survival, as reflected by the reduced need for intubation and by the mortality rate, and the absence of acute kidney injury suggest that the ELMO CPAP system is a promising tool for treating ARDS and similar clinical conditions.

RESUMO Objetivo: Avaliar se o uso do ELMO, um capacete para ventilação não invasiva criado no Brasil, teve impacto positivo no prognóstico de pacientes com insuficiência respiratória hipoxêmica por COVID-19 grave. Métodos: Estudo retrospectivo com 50 pacientes críticos com COVID-19. Dados epidemiológicos, clínicos e laboratoriais foram coletados na admissão na UTI e antes, durante e após o uso do ELMO. Os pacientes foram divididos em dois grupos (sucesso e falha) de acordo com o desfecho. Resultados: O uso do ELMO melhorou parâmetros de oxigenação como Pao2, Fio2 e relação Pao2/Fio2, e isso contribuiu para uma redução gradual da Fio2, sem aumento do CO2, conforme determinado pela gasometria arterial. Os pacientes do grupo sucesso apresentaram sobrevida significativamente maior (p < 0,001), conforme determinado pela análise de Kaplan-Meier, menor necessidade de intubação (p < 0,001), menos dias de hospitalização e menor incidência de lesão renal aguda em comparação com os do grupo falha. Conclusões: A significativa melhora nos parâmetros de oxigenação, a maior sobrevida, refletida pela menor necessidade de intubação e pela taxa de mortalidade, e a ausência de lesão renal aguda sugerem que o sistema ELMO CPAP é uma ferramenta promissora para o tratamento da SDRA e de condições clínicas semelhantes.

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

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

ABSTRACT HIV-infected patients are at high risk for developing critical diseases, including opportunistic infections (OI), with consequent admission in intensive care units (ICU). Renal disfunctions are risk factors for death in HIV/AIDS patients, and survival rates in patients undergoing hemodialysis are smaller than the ones observed in the general population. In this context, this study aimed to investigate death-related factors in HIV/AIDS patients in an intensive care setting. This is a retrospective cross-sectional study performed through the analysis of medical records from 271 HIV/AIDS-diagnosed patients hospitalized in an intensive care unit of an infectious disease hospital, in Fortaleza, Ceara State, Brazil. Patients were divided into two groups: those who underwent dialysis during hospitalization and those who did not. Clinical and demographic parameters that could be associated with death were evaluated. Results indicated a prevalence of death of 19.1% (CI 95%: 14.8-24.3). The median age of patients was 47 years, with a male predominance (71.3%). The main causes of admission were pulmonary tuberculosis (16.9%), followed by neurotoxoplasmosis (14.9%). In the bivariate analysis, for those that did not undergo dialysis, age, fever, dyspnea, oliguria, disorientation, kidney injury, use of lamivudine and efavirenz, length of hospitalization, CD4 count, WBC count, platelet count, urea, sodium and LDH levels were the associated variables. In those who needed dialysis, the use of stavudine, abacavir and ritonavir, and the length of hospitalization were associated factors. Renal toxicity by the antiretroviral agents and length of hospitalization increased the risk of death among HIV patients under dialysis.

RESUMO Objetivos: identificar as evidências científicas acerca das complicações e manifestações clínicas da sífilis congênita e aspectos relacionados à prevenção. Métodos: revisão integrativa, mediante busca nas bases de dados LILACS e MEDLINE, realizada em março de 2018, utilizando os descritores “syphilis, congenital”, “complications”, “signs and symptoms”, resultando em 27 pesquisas selecionadas. Resultados: encontraram-se publicações entre os anos de 1966 e 2017, na maioria oriundas da América Latina e África. O desfecho desfavorável, a alteração laboratorial e as manifestações clínicas da sífilis congênita precoce e tardia mais evidenciados foram, respectivamente, baixo peso ao nascer, anemia, hepatoesplenomegalia e alterações odontológicas. Observou-se que a falta de tratamento da gestante no pré-natal foi a principal oportunidade perdida de prevenção das complicações da sífilis congênita. Conclusões: as evidências científicas analisadas apresentam graves complicações da sífilis congênita que seriam evitadas desde que oportunidades precoces de diagnóstico e tratamento da gestante não fossem perdidas durante o pré-natal.

ABSTRACT Objectives: to identify the scientific evidence about the clinical complications and manifestations of congenital syphilis and aspects related to its prevention. Methods: integrative review after a search in the databases LILACS and MEDLINE, carried out in March 2018, using the descriptors “syphilis, congenital”, “complications”, and “signs and symptoms”, leading to the selection of 27 researches. Results: the publications found were published from 1966 to 2017, and most of them were from Latin America and Africa. Negative outcomes, laboratory changes, and the clinical manifestations in congenital syphilis, whether early or delayed, were, respectively: low weight at birth, anemia, hepatosplenomegaly, and dental alterations. The lack of treatment of the pregnant women in the prenatal was the most common occasion in which the opportunity to prevent the complications of congenital syphilis was lost. Conclusions: the scientific evidences analyzed showed serious complications of congenital syphilis that could be avoided if early opportunities of diagnosing and treating the pregnant women are not lost during the prenatal.

ABSTRACT Bothrops erythromelas are serpents that belong to the Viperidae family, which are the main species responsible for human snakebites in Ceara State, Northeast Brazil. Thrombotic microangiopathy (TMA) is an uncommon group of disorders characterized by microangiopathic hemolytic anemia (MAHA), thrombocytopenia and acute kidney injury (AKI), and occurrence after snakebites have been rarely reported. In this report, we described the case of a 57 year-old-man without comorbidities who was bitten by a Bothrops erythromelas on his right ankle. He presented with pain, edema and local bleeding. Symptomatology and laboratory tests were compatible with the diagnosis of TMA. He received specific antivenom and fluids replacement without any anaphylactic reaction. The conservative treatment was effective and there was no need for red blood cells transfusion or plasmapheresis. The aim of this report was to describe the first case of thrombotic microangiopathy following Bothrops erythromelas envenoming in the Northeast Brazil, providing insights about important mechanistic pathways of Bothrops snakebite-associated TMA and how to change the prognosis of the disease.

Abstract Bothrops are one of the most common medically important snakes found in Latin America. Its venom is predominantly hemotoxic and proteolytic, which means that local lesion (edema and redness) and hemorrhagic symptoms are recurrent in envenoming by this snake. Although hemorrhage is usually the major cause of death, snakebite-related acute kidney injury is another potentially fatal clinical complication that may lead to chronic kidney disease. The present review highlights the main studies on Bothrops venom-related acute kidney injury, including observational, cross-sectional, case-control and cohort human studies available up to December 2019. The following descriptors were used according to Medical Subject Headings (MeSH): on Medline/Pubmed and Google Scholar “acute kidney injury” or “kidney disease” and “Bothrops”; on Lilacs and SciELO “kidney disease” or “acute kidney injury” and “Bothrops”. Newcastle-Ottawa quality assessment scale was used to appraise the quality of the cross-sectional and cohort studies included. The selection of more severe patients who looked for health care units and tertiary centers is a risk of bias. Due to the methodological heterogeneity of the studies, a critical analysis of the results was performed based on the hypothesis that the design of the included studies influences the incidence of acute kidney injury. Fifteen human studies (total participants 4624) were included according to stablished criteria. The coagulation abnormalities (hemorrhagic symptoms, abnormal fibrinogen and activated partial thromboplastin time) were associated with acute kidney injury in the most recent studies reported. The findings observed in this review provide up-to-date evidence about the acute kidney injury pathogenesis following Bothrops syndrome. Studies pointed out that coagulation abnormalities comprise the major pathway for acute kidney injury development. This review may improve patient management by primary healthcare providers, allowing earlier diagnosis and treatment of Bothrops venom-related acute kidney injury.

Abstract INTRODUCTION: Loxoscelism is a clinical condition involving spiders of the genus Loxosceles. One of the most severe complications is acute kidney injury (AKI). This study aimed to investigate AKI and other complications associated with loxoscelism. METHODS: We analyzed cases diagnosed with loxoscelism in an area where most accidents were caused by Loxosceles amazonica from January 2010 to December 2015. AKI was defined according to the KDIGO criteria. RESULTS: Forty-five patients were recorded: 95.6% presented characteristic necrotic skin lesions and 13.3% AKI. CONCLUSIONS: Loxoscelism could cause kidney involvement which is uncommon and could lead to the death of these patients.

Pyelonephritis is a pyogenic infection of renal parenchyma that involves the renal pelvis. It is generally of easy diagnosis. The present case report aims to describe two different manifestations of this infection: xanthogranulomatous pyelonephritis and emphysematous pyelonephritis, which have poor prognosis and require a more effective treatment. The two cases were women in the fiftieth and sixtieth decade of life, with diabetes mellitus and history of weight loss. The diagnosis of the renal infection was established through computed tomography and the treatment was based in surgical procedure, with favorable outcome.

O envolvimento renal na hanseníase é diverso, incluindo glomerulonefrites, amiloidose e nefrite túbulo-intersticial. Um homem de 58 anos foi admitido com edema de membros inferiores e dispnéia. Na admissão, havia retenção de escórias nitrogenadas, anemia, hipercalemia e acidose metabólica, com necessidade de hemodiálise. Referia história de hanseníase virchoviana. Foi realizada biopsia renal, compatível com amiloidose. O paciente evoluiu estável, sem recuperação da função renal, permanecendo em tratamento hemodialítico. A hanseníase deve ser investigada em todo paciente com perda de função renal, sobretudo naqueles que apresentam lesões cutâneas ou outras manifestações sugestivas de hanseníase.

Renal involvement in leprosy includes glomerulonephritis, amyloidosis and tubulointerstitial nephritis. A 58-year-old man was admitted with complaints of lower limb edema and dyspnea. At admission, nitrogen retention, anemia, hyperkalemia and metabolic acidosis were observed, requiring hemodialysis. The patient had a history of lepromatous leprosy. A renal biopsy was performed that was compatible with amyloidosis. The patient had a stable outcome, but without renal function recovery and remained on regular hemodialysis. Leprosy should be investigated in every patient with renal function loss, particularly in those with cutaneous lesions or other manifestations suggestive of leprosy.

OBJETIVO: A população idosa está aumentando em todo o mundo, assim como a necessidade de cuidados intensivos para os idosos. Existem poucos estudos que investiguem os fatores de risco para óbito em pacientes idosos gravemente enfermos. Este estudo teve o objetivo de investigar os fatores associados ao óbito em uma população de pacientes idosos gravemente enfermos admitidos a uma unidade de terapia intensiva no Brasil. MÉTODOS: Estudo retrospectivo de coorte que incluiu todos os pacientes idosos (idade ≥ 60 anos) admitidos a uma unidade de terapia intensiva em Fortaleza, Brasil, de janeiro a dezembro de 2007. Foi realizada uma comparação entre os sobreviventes e os não sobreviventes, e os fatores de risco para óbito foram investigados por meio de análise univariada e multivariada. RESULTADOS: Foi incluído um total de 84 pacientes, com uma média de idade de 73 ± 7,6 anos, sendo 59% do gênero feminino. A mortalidade foi de 62,8%. A principal causa de morte foi disfunção de múltiplos órgãos (42,3%), seguido por choque séptico (36,5%) e choque cardiogênico (9,7%). As complicações durante a permanência na unidade de terapia intensiva associadas com óbito foram insuficiência respiratória (OR = 61; p<0.001), lesão renal aguda (OR =23, p<0,001), sepse (OR = 12; p<0,001), acidose metabólica (OR = 17; p<0,001), anemia (OR = 8,6; p<0,005), distúrbios da coagulação (OR = 5,9; p<0,001) e fibrilação atrial (OR = 4,8; P<0,041). Os fatores de risco independentes para óbito foram idade (OR = 1,15; p<0,005), coma (OR = 7,51; p<0,003), hipotensão (OR = 21,75; p=0,003), insuficiência respiratória (OR = 9,93; p<0,0001), e lesão renal aguda (OR = 16,28; p<0,014). CONCLUSÕES: A mortalidade é elevada em pacientes idosos gravemente enfermos. Os fatores associados ao óbito foram idade, coma, hipotensão, insuficiência respiratória e lesão renal aguda.

BACKGROUND: The elderly population is increasing all over the world. The need of intensive care by the elderly is also increasing. There is a lack of studies investigating the risk factors for death among critically ill elderly patients. This study aims to investigate the factors associated with death in a population of critically ill elderly patients admitted to an intensive care unit in Brazil. METHODS: This is a retrospective cohort study including all elderly patients (>60 years) admitted to an intensive care unit in Fortaleza, Brazil, from January to December 2007. A comparison between survivors and nonsurvivors was done and the risk factors for death were investigated through univariate and multivariate analysis. RESULTS: A total of 84 patients were included, with an average age of 73 ± 7.6 years; 59% were female. Mortality was 62.8%. The main cause of death was multiple organ dysfunction (42.3%), followed by septic shock (36.5%) and cardiogenic shock (9.7%). Complications during intensive care unit ICU stay associated with death were respiratory failure (OR=61, p<0.001), acute kidney injury (OR=23, p<0.001), sepsis (OR=12, p<0.001), metabolic acidosis (OR=17, p<0.001), anemia (OR=8.6, p<0.005), coagulation disturbance (OR=5.9, p<0.001) and atrial fibrillation (OR=4.8, p<0.041). Independent risk factors for death were age (OR=1.15, p<0.005), coma (OR=7.51, p<0.003), hypotension (OR=21.75, p=0.003), respiratory failure (OR=9.93, p<0.0001) and acute kidney injury (OR=16.28, p<0.014). CONCLUSION: Mortality is high among critically ill elderly patients. Factors associated with death were age, coma, hypotension, respiratory failure and acute kidney injury.

O lítio é amplamente empregado na terapia do transtorno bipolar. Sua toxicidade renal inclui distúrbio na capacidade de concentração urinária e natriurese, acidose tubular renal, nefrite túbulo-intersticial evoluindo para doença renal crônica e hipercalcemia. O efeito adverso mais comum é o diabetes insipidus nefrogênico, que acomete de 20%-40% dos pacientes semanas após o início do tratamento. A nefropatia crônica correlaciona-se com a duração do uso de lítio. A detecção precoce de disfunção renal deve ser feita através de monitoração rigorosa dos pacientes e colaboração entre o psiquiatra e o nefrologista. Recentes trabalhos experimentais e clínicos começam a esclarecer os mecanismos pelos quais o lítio induz alteração da função renal. No presente trabalho, objetivamos revisar a patogênese, a apresentação clínica, os aspectos histopatológicos e o tratamento da nefrotoxicidade induzida pelo lítio.

Lithium is widely used in the therapy of bipolar disorder. Its toxicity includes urinary concentration deficit and natriuresis, renal tubular acidosis, tubulointerstitial nephritis which complicates with chronic kidney disease and hypercalcemia. The most common adverse effect is diabetes insipidus, which occurs in 20-40% of patients some weeks after initiation of treatment. Such chronic nephropathy correlates with duration of lithium use. Early detection of renal dysfunction should be achieved by rigorous monitoring of patients and collaboration between the psychiatrist and nephrologist. Recent experimental and clinical studies are now clarifying the mechanisms by which lithium induces renal abnormalities. The aim of this work is to review the pathogenesis, clinical presentation, histopathologic aspects and treatment of lithium nephrotoxicity.
