Brazilian Dialysis Survey 2022 / Censo Brasileiro de Diálise 2022

Abstract Introduction: The Brazilian Dialysis Survey (BDS) is an annual national survey about patients on chronic dialysis that contributes to health policies. Objective: To report the 2022 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN). Methods: A survey was carried out in Brazilian chronic dialysis centers using an online questionnaire that included clinical and epidemiological aspects of patients on chronic dialysis, dialysis therapy data, and dialysis center characteristics. Results: Overall, 28% (n = 243) of the centers answered the questionnaire. In July 2022, the estimated total number of patients on dialysis was 153,831. The estimated prevalence and incidence rates of patients per million population (pmp) were 758 and 214, respectively. Of the prevalent patients, 95.3% were on hemodialysis (HD, 4.6% of these on hemodiafiltration) and 4.7% on peritoneal dialysis (PD). Only 1.3% of patients were not vaccinated against COVID-19. The prevalence of anemia (Hb < 10g/dL) was 27% and hyperphosphatemia (P > 5.5mg/dL) reached 30%. The estimated overall crude annual mortality rate was 17.1%. Conclusions: The absolute number and prevalence rate of patients on chronic dialysis continue to increase. A growing number of patients were receiving hemodiafiltration. The mortality rate decreased, probably due to the end of COVID-19 pandemic. The conclusions were drawn in the context of relatively low voluntary participation, which imposed methodological limitations on our estimates.

Resumo Introdução: O Censo Brasileiro de Diálise (CBD) é uma pesquisa nacional anual sobre pacientes em diálise crônica que contribui para as políticas de saúde. Objetivo: Informar os dados epidemiológicos de 2022 do CBD da Sociedade Brasileira de Nefrologia (SBN). Métodos: Foi realizada uma pesquisa em centros brasileiros de diálise por meio de um questionário online que incluiu aspectos clínicos e epidemiológicos de pacientes em diálise crônica, dados da terapia dialítica e características do centro de diálise. Resultados: No total, 28% (n = 243) dos centros de diálise ativos cadastrados na SBN responderam ao questionário. Em julho de 2022, o número total estimado de pacientes em diálise era de 153.831. As taxas estimadas de prevalência e incidência de pacientes por milhão (ppm) de habitantes foram 758 e 214, respectivamente. Dos pacientes prevalentes, 95,3% estavam em hemodiálise (HD; 4,6% desses em hemodiafiltração) e 4,7% em diálise peritoneal (DP). Apenas 1,3% dos pacientes não foram vacinados contra a COVID-19. A prevalência de anemia (Hb < 10g/dL) foi de 27% e de hiperfosfatemia (P > 5,5mg/dL) alcançou 30%. A taxa bruta total anual de mortalidade estimada foi de 17,1%. Conclusões: O número absoluto e a taxa de prevalência de pacientes em diálise crônica continuam a aumentar. Um número crescente de pacientes estava em hemodiafiltração. A taxa de mortalidade diminuiu, provavelmente devido ao fim da pandemia da COVID-19. As conclusões foram de um contexto de participação voluntária relativamente baixa, o que impõe limitações metodológicas às nossas estimativas.

Correlation analysis between peripheral blood dendritic cell subsets and PD-1 in patients with peritoneal adenocarcinoma

Abstract The aim of this study was to explore the association between differential percentages of dendritic cell (DC) subsets in peripheral blood and malignancy (grade and lymph node metastasis) of peritoneal adenocarcinoma patients and the frequencies of dendritic cell subsets in the normal controls. The peripheral blood of 30 patients with peritoneal adenocarcinoma and 12 healthy controls were collected for multicolor flow cytometry analysis. Peritoneal adenocarcinoma patients were grouped according to the malignant degree (grade and lymph node metastasis). Percentages of myeloid DCs (mDCs) and its subsets MDC1 and MDC2 in DCs were lower in peripheral blood of patients with peritoneal adenocarcinoma than in normal controls. The percentages of plasmacytoid dendritic cells (pDCs) and CD16+mDCs in DCs were higher than in normal controls. Compared with poor differentiation grade, patients with well/moderate differentiation grade had an increased percentage of CD16+mDCs. Contrary to CD16+mDCs, the percentage of MDC1 was lower in the well/moderate differentiation grade group. In patients with no lymph node metastasis, pDCs and CD16+mDCs levels were higher compared with patients with lymph node metastasis. mDCs and MDC1 levels had opposite results. pDCs were positively correlated with CD16+mDCs in peripheral blood of peritoneal patients, as was mDCs and MDC1. CD16+mDCs were negatively correlated with MDC1. The percentages of pDCs and CD16+mDCs in DCs were positively correlated with CD3+CD8+T cells, and pDCs also positively correlated with CD8+PD-1+T cells. Our results revealed that DCs subsets correlated with peritoneal adenocarcinoma malignancy. Dendritic cells play an independent role in the immune function of peritoneal adenocarcinoma.

Catéter peritoneal tunelizado para el manejo de ascitis refractaria en paciente con síndrome nefrótico

Introducción: la ascitis refractaria puede ser una complicación frecuente en el síndrome nefrótico (SN), existen casos reportados del uso de un catéter tunelizado de diálisis peritoneal en pacientes con cirrosis o neoplasias abdominales. Se presenta el caso de un paciente con SN en quién se utilizó un catéter para diálisis peritoneal (DP) para manejo de la ascitis refractaria. Objetivo: mostrar que el catéter peritoneal puede ser considerado como una alternativa para el manejo de la ascitis refractaria en pacientes con síndrome nefrótico. Presentación del caso: paciente varón de 19 años, sin antecedentes patológicos, cursó con edema progresivo y alteración de la función renal. Se evidenció síndrome nefrótico con anasarca y evolucionó con empeoramiento de la función renal ingresando a hemodiálisis de soporte. Se realizó biopsia renal: podocitopatía, glomerulopatía colapsante. Se inició tratamiento con corticoterapia, mejorando la función renal hasta suspender la hemodiálisis, pero presentó ascitis refractaria al tratamiento médico, por lo que se realizó paracentesis evacuatoria en reiteradas ocasiones. Se decidió colocación de catéter peritoneal tunelizado para el manejo de la ascitis refractaria. La ascitis fue disminuyendo progresivamente hasta el retiro del catéter peritoneal. Discusión y conclusión: el uso de catéter tunelizado de diálisis peritoneal es una opción de manejo efectiva en casos de síndrome nefrótico con ascitis refractaria.

Introduction: Refractory ascites can be a frequent complication in nephrotic syndrome (NS), there are reported cases of the use of a tunneled peritoneal dialysis catheter in patients with cirrhosis or abdominal neoplasms. The case of a patient with NS is presented in whom used a peritoneal dialysis (PD) catheter to manage refractory ascites. Purpose: To show that the peritoneal catheter can be considered as an alternative for the management of refractory ascites in patients with nephrotic syndrome. Presentation of the case: A 19-year-old male patient, with no pathological history, presented progressive edema and impaired renal function. Nephrotic syndrome with anasarca was evidenced, and it evolved with worsening renal function, entering supportive hemodialysis. Renal biopsy was performed: podocytopathy, collapsing glomerulopathy. Corticosteroid treatment was started, improving renal function until hemodialysis was discontinued, but he presented ascites refractory to medical treatment, for which evacuatory paracentesis was performed repeatedly. It was decided to place a tunneled peritoneal catheter for the management of refractory ascites. Ascites gradually decreased until the peritoneal catheter was removed. Discussion and conclusion: The use of a tunneled peritoneal dialysis catheter is an effective management option in cases of nephrotic syndrome with refractory ascites.

Objective: to evaluate the evidence about telehealth strategies in caring for people with chronic kidney disease. Method: integrative literature review. The search for primary studies was carried out in six databases: PubMed/MEDLINE, Web of Science, EMBASE, CINAHL, LILACS, and Scopus. The sample consisted of 48 articles published between 2000 and 2021. The telehealth strategy was applied by a multidisciplinary team of doctors, nurses, pharmacists, nutritionis, and social workers. The type of study, country, strategy applied, setting, population, and professional were extracted from the articles. The studies were selected by reading the title and abstract (phase 1) and then reading them in full (phase 2), categorizing them by telehealth strategy. The results were summarized descriptively and the studies were classified according to their level of evidence. Results: the home was the most representative in dialysis and conservative treatment. Six categories of telehealth strategies were identified: remote monitoring devices, teleconsultation, digital platforms, apps, multimodality strategies, and telephone contact. Conclusion: using these strategies for the care of people with chronic kidney disease presents different forms and implementations, being feasible for the renal population at any stage of the disease and applicable by different health professionals with an emphasis on the home environment. The evidence shows that telehealth favors lower cost, accessibility to remote locations, and better monitoring of dialysis with positive resul in symptom control, risk reduction, and patient training.

Severe Manifestation of Peritoneal Tuberculosis: Clinical Case Report

Aim: To describe the clinical manifestation and the diagnostic process of a patient with peritoneal tuberculosis as a clinical challenge in a tertiary referral center in a Latin American country. Case description: A 61-year-old male patient from the urban area of Cali consulted for edema in the lower limbs, ascites, hyporexia, weight loss, cachexia, thrombocytopenia, elevated transaminases, imaging of splenomegaly and pulmonary, hepatic, and peritoneum nodules. Initially, neoplasia was suspected, but the adenosine deaminase report and histopathology were consistent with the diagnosis of peritoneal tuberculosis. Conclusion: Peritoneal tuberculosis represents the sixth cause of extrapulmonary tuberculosis, after lymphatic, pleural, osteoarticular, genitourinary, and meningeal manifestations. Despite having surveillance systems, peritoneal tuberculosis is still considered the most challenging infectious disease to reach a definitive diagnosis. We present a case of disseminated tuberculosis in which invasion of the peritoneum was verified, for which tetraconjugate treatment was started; however, the patient showed an adverse hepatic reaction and died due to multisystem involvement of a pulmonary infectious complication.

Objetivo: describir la presentación clínica y el proceso diagnóstico de un paciente con tuberculosis peritoneal como reto clínico en un centro de alta complejidad de un país latinoamericano. Descripción del caso: un paciente masculino de 61 años procedente del área urbana de Cali consultó por edema en los miembros inferiores, ascitis, hiporexia, pérdida de peso, caquexia, trombocitopenia, elevación de transaminasas, imágenes de esplenomegalia y nódulos pulmonares, hepáticos y en el peritoneo. Inicialmente se sospechó neoplasia, pero el reporte de adenosina desaminasa y la histopatología fueron consistentes con el diagnóstico de tuberculosis peritoneal. Conclusión: la tuberculosis peritoneal representa la sexta causa de tuberculosis extrapulmonar, después de las manifestaciones linfáticas, pleurales, osteoarticulares, genitourinarias y meníngeas. A pesar de contar con sistemas de vigilancia, la tuberculosis peritoneal sigue siendo considerada como la enfermedad infecciosa más desafiante para llegar a un diagnóstico definitivo. Se presenta un caso de tuberculosis diseminada en el que se comprobó invasión del peritoneo, por lo que se inició un tratamiento tetraconjugado; sin embargo, presentó una reacción adversa hepática y falleció producto del compromiso multisistémico de una complicación infecciosa pulmonar.

Peritonitis asociada a diálisis peritoneal causada por el complejo Paecilomyces variotii

La peritonitis asociada a diálisis peritoneal es una complicación grave en el paciente con este tipo de modalidad de terapia de reemplazo renal, siendo la etiología fúngica una de las que conlleva mayor morbimortalidad. Presentamos el caso de un paciente de 22 años que desarrolló una peritonitis asociada a diálisis peritoneal causada por el complejo Paecilomyces variotii; un hongo filamentoso poco frecuente en este grupo de pacientes.

Peritonitis associated with peritoneal dialysis is a serious complication in patients with this type of renal replacement therapy modality, with fungal aetiology being one of the most associated with morbidity and mortality. We present the case of a 22-year-old patient who developed fungal peritonitis associated with peritoneal dialysis caused by Paecilomyces variotii complex; a rare cause of peritonitis in this group of patients.

STRN-ALK rearranged malignant peritoneal mesothelioma—Presenting with bilateral extensive pelvic masses in a young woman: Mimicking low-grade serous ovarian carcinoma

Malignant peritoneal mesothelioma (MPM) is an exceptionally rare tumor type. Although some somatic/germline genetic alterations including BAP1 loss have been identified in some cases, the molecular properties of MPMs are remained poorly understood. In recent years, anaplastic lymphoma kinase (ALK) gene rearrangement was revealed in a subset of (3.4%) MPMs. Low-grade serous carcinomas (LGSCs) are a rare subtype of ovarian carcinoma and have some morphologic and immunophenotypic overlapping features with MPMs and this may cause misdiagnosis in daily practice. Here, we report a case of 18-year-old women with STRN-ALK-rearranged MPM and no previous exposure to asbestos. This case was presented with bilateral pelvic masses and histologically was displaying pure papillary morphology with mild-to-moderate nuclear atypia, psammoma bodies, and diffuse PAX8 expression as LGSCs. With the detection of ALK alteration in some of the MPMs, a targeted treatment option has emerged for these unusual tumor types.

Peritoneal sarcomatosis due to undifferentiated pleomorphic sarcoma: A case report and review of the literature

Undifferentiated pleomorphic sarcoma (UPS), which was previously known as malignant fibrous histiocytoma (MFH), rarely presents in the abdomen, and sarcomatosis due to UPS has not yet been reported in the literature. Here, we present a 62-year-old man who had abdominal sarcomatosis due to UPS with a poor prognosis.

Infección simultánea del Injerto Renal por virus BK y CMV: reporte de casos / Simultaneous infection of the renal graft by BK virus and CMV: case report

RESUMEN El camino para llegar a la diálisis peritoneal (DP) como tratamiento de la enfermedad renal crónica (ERC) avanzada estuvo jalonado por hitos a lo largo de la historia. Los conocimientos sobre la anatomía del peritoneo fueron aportados por los embalsamadores egipcios, Galeno (siglo II), y Vesalio (siglo XVI). Recién en 1628 Asellius Gaselli describe los capilares linfáticos abdominales. El siglo XIX fue rico en avances: se identificarn la célula como unidad de los seres vivos y el fenómeno de ósmosis (Dutrochet, 1828), los cristaloides y coloides y su pasaje o no a través de una membrana (Graham T, 1850), el flujo de solutos y partículas a través de la membrana peritoneal (v.Recklinghausen, 1863), la absorción de sustancias hipotónicas y el aumento del efluente con las hipertónicas (Wegner G, 1877), y experimentos en animales confirmaron que la remoción de fluidos y otras sustancias ocurría primariamente a través de vasos sanguíneos (Starling & Tubby, 1894). Pero recién en el siglo 20 se utilizó la DP como tratamiento. El primer intento de utilizar el peritoneo para tratar la uremia lo realizó Georg Ganter en 1923, primero en animales con ligadura de uréteres y luego en dos pacientes. Recién en 1937 se publicó el primer caso que sobrevivió a un "lavaje "peritoneal (Wear y col), pero fueron Fine, Frank y Seligman quienes inicialmente en perros nefrectomizados y luego en pacientes con injuria renal aguda (IRA) demostraron que el método no sólo era viable, sino también efectivo. Luego continuaron los progresos, sobre todo para pacientes con IRA, pero también en algunos casos con ERC avanzada: el doble frasco colgante (Maxwell M, 1959), la diálisis crónica intrahospitalaria con cicladora (Tenckoff y col, 1965), las bolsas plásticas para DP, hasta que en 1975 Moncrief y col pusieron en marcha la DP continua ambulatoria, y en 1981 se introdujo la DP automatizada. Los años noventa fueron de expansión de la DP, hoy instalada como una de las alternativas de tratamiento de la ERC avanzada.

ABSTRACT Milestones throughout history marked the path to reach peritoneal dialysis (PD) as a treatment for advanced chronic kidney disease (CKD). The Egyptian embalmers, Galen (2nd century) and Vesalius (16th century) provided knowledge about the anatomy of the peritoneum. It was not until 1628 that Asellius Gaselli described the abdominal lymphatic capillaries. The 19th century was rich in advances: the cell was identified as the unit of living beings and the phenomenon of osmosis (Dutrochet, 1828), crystalloids and colloids and their passage or not through a membrane (Graham T, 1850), the flow of solutes and particles through the peritoneal membrane (Recklinghausen, 1863), the absorption of hypotonic substances and the increase in effluent with hypertonic ones (Wegner G, 1877), and animal experiments confirmed that fluid removal and other substances occurred primarily through blood vessels (Starling & Tubby, 1894). But it was not until the 20th century that PD was applied as treatment. The first attempt to use the peritoneum to treat uremia was made by Georg Ganter in 1923, first in animals with ureteral ligation and then in two patients. It was not until 1937 that the first case that survived a peritoneal "lavage" was published (Wear et al), but it was Fine, Frank and Seligman who initially in nephrectomized dogs and later in patients with acute kidney injury (ARI) demonstrated that the method was not only viable, but also succesful. Then progress continued, especially for patients with ARI, but also in some cases with advanced CKD: the double hanging bottle (Maxwell M, 1959), chronic intrahospital dialysis with a cycler (Tenckoff et al, 1965), plastic bags for PD, until 1975 when Moncrief et al launched continuous ambulatory PD, and in 1981 automated PD was introduced. The 1990s saw the expansion of PD, to date installed as one of treatment alternatives for advanced CKD.

Prevalencia de peritonitis asociada a diálisis peritoneal en el Hospital Central Militar / Prevalence of peritonitis associated with peritoneal dialysis in the Central Military Hospital

Resumen La definición de la enfermedad renal crónica (ERC) es la disminución del filtrado glomerular (FG) por debajo de 60 ml/min/1.73 m2, durante tres o más meses, acompañada por anormalidades estructurales o funcionales. México reporta una incidencia de 467/1 000 00 casos de ERC. La modalidad de diálisis más utilizada es la diálisis peritoneal y la complicación más común es la peritonitis. Se obtuvo la prevalencia de peritonitis en pacientes con diálisis peritoneal del HCM en 2021, determinar las comorbilidades asociadas a la ERC, la diferencia entre diálisis automatizada y continua ambulatoria, sus desenlaces y la mortalidad global. Estudio observacional, descriptivo, transversal. Pacientes con diálisis peritoneal atendidos durante 2021 en nefrología del HCM. Se recolectaron y analizaron los datos, utilizando estadística descriptiva e inferencial determinado la prevalencia de peritonitis, las diferencias entre la modalidad de diálisis peritoneal y los episodios de peritonitis. Se analizaron 339 pacientes atendidos en el HCM, durante un año, la prevalencia de peritonitis fue de 0.2625 peritonitis/paciente/año, las comorbilidades fueron la hipertensión (70.5%) y la diabetes mellitus (65.19%), entre los grupos de diálisis peritoneal automatizada y diálisis peritoneal continua ambulatoria no hubo diferencia y la mortalidad general fue 6.48%. La peritonitis es la principal complicación en diálisis peritoneal, la prevalencia en el HCM esta por abajo de la media del país y del mundo siendo esta del 26.25%. Las Guías de la Sociedad Internacional de la Diálisis Peritoneal recomiendan mantener una prevalencia por abajo de 0.5 episodios de peritonitis por paciente por año.

Abstract The definition of the Chronic Kidney Disease (CKD) is the decrease in glomerular filtration rate (GFR) below 60 ml/min/1.73 m2, for 3 or more months, accompanied by structural or functional abnormalities. Mexico reports an incidence of 467/1,000,000 cases of CKD. The most used dialysis modality is peritoneal dialysis, and the most common complication is peritonitis. We obtained the prevalence of peritonitis in patients with peritoneal dialysis in HCM in 2021, to determine the comorbidities associated with CKD, the difference between automated and continuous ambulatory dialysis, its outcomes, and overall mortality. Observational, descriptive, cross-sectional study. Patients with peritoneal dialysis attended during 2021 in HCM nephrology. Data were collected and analyzed using descriptive and inferential statistics to determine the prevalence of peritonitis and the differences between the modality of peritoneal dialysis and the episodes of peritonitis. The prevalence of peritonitis was 0.2625 peritonitis/patient/year, and the comorbidities were hypertension (70.5%) and diabetes mellitus (65.19%), between the groups of Automated Peritoneal Dialysis and Continuous Ambulatory Peritoneal Dialysis there was no difference, and the overall mortality was 6.48%. Peritonitis is the main complication in peritoneal dialysis, the prevalence of HCM is below the country and world average of 26.25%. International Guidelines recommend maintaining a prevalence below 0.5 episodes of peritonitis per patient per year.

Equinococosis quística peritoneal diseminada en paciente con infección Por VIH: reporte de caso / Disseminated peritoneal cystic Echinococcosis in a patient with HIV: case report

RESUMEN La equinococosis quística es una infección zoonótica producida por la larva de Echinococcus granulosus que es capaz de invadir diversos órganos desde su ubicación en el intestino humano. En los casos de coinfección con el virus de la inmunodeficiencia humana (VIH), existe una diversidad de complicaciones condicionadas por la enfermedad inmunosupresora con pronóstico reservado. El objetivo de este reporte es describir un caso de equinococosis multiquística peritoneal en una paciente en tratamiento antiviral para VIH durante casi diez años, que recibió la combinación de albendazol más cirugía, con evolución favorable. Este reporte sería el primero en el Perú en una persona con inmunosupresión por VIH y equinococosis quística.

ABSTRACT Cystic echinococcosis is a zoonotic infection caused by the larva of Echinococcus granulosus, which is capable of invading several organs starting from the human intestine. There are several complications in cases of co-infection with the human immunodeficiency virus (HIV), which are conditioned by the immunosuppressive disease and have poor prognosis. This report aims to describe a case of multi-cystic peritoneal echinococcosis in a patient under antiviral treatment for HIV for almost ten years, who received albendazole, underwent surgery and progressed favorably. This would be the first Peruvian report of a person with HIV and cystic echinococcosis.

Brazilian Dialysis Survey 2021 / Censo Brasileiro de Diálise 2021

ABSTRACT Introduction: The Brazilian Dialysis Survey (BDS) is an important source of national data about people on chronic dialysis that contributes to the formulation of health policies regarding kidney failure. Objective: To report the 2021 epidemiological data from the BDS of the Brazilian Society of Nephrology (BSN). Methods: A survey was carried out in Brazilian chronic dialysis centers using an online questionnaire covering clinical and epidemiological aspects of patients in chronic dialysis, data on dialysis therapy, characteristics of dialysis centers, and the impact of the COVID-19 pandemic of 2021. Results: Thirty percent (n = 252) of the centers answered the questionnaire. In July 2021, the estimated total number of patients on dialysis was 148,363. The estimated prevalence and incidence rates of patients per million population (pmp) were 696 and 224, respectively. Of the prevalent patients, 94.2% were on hemodialysis (HD) (1.8% of these on hemodiafiltration), and 5.8% on peritoneal dialysis (PD); 21% were on the transplant waiting list. The incidence rate of confirmed COVID-19 between January and July 2021 was 1,236/10,000 dialysis patients, and the case-fatality rate reached 25.5%. Up to July 2021, 88.6% of patients had received at least one dose of the anti-SARS-CoV-2 vaccine. The estimated overall and COVID-19 crude annual mortality rates were 22.3% and 5.3%, respectively. Conclusion: The absolute number and the prevalence rate of patients on chronic dialysis continue to increase. Most dialysis patients were vaccinated against COVID-19 during the year. The COVID-19 pandemic was associated to the overall mortality rate.

RESUMO Introdução: O Censo Brasileiro de Diálise (CBD) constitui importante fonte de dados nacionais sobre pessoas em diálise crônica que contribui para a formulação de políticas de saúde. Objetivo: Relatar dados epidemiológicos de 2021 do CBD da Sociedade Brasileira de Nefrologia (SBN). Métodos: Realizou-se pesquisa em centros brasileiros de diálise crônica utilizando questionário online abrangendo aspectos clínicos e epidemiológicos de pacientes em diálise crônica, dados sobre terapia dialítica, características dos centros de diálise e o impacto da pandemia COVID-19 em 2021. Resultados: Trinta por cento (n = 252) dos centros responderam ao questionário. Em Julho de 2021, o número total estimado de pacientes em diálise foi 148.363. As taxas estimadas de prevalência e incidência de pacientes por milhão da população (pmp) foram 696 e 224, respectivamente. Dos pacientes prevalentes, 94,2% estavam em hemodiálise (HD) (1,8% destes em hemodiafiltração), e 5,8% em diálise peritoneal (DP); 21% estavam na lista de espera para transplante.

PERIOPERATIVE CONCERNS OF VENTRICULOATRIAL SHUNT-A RETROSPECTIVE ANALYSIS OF 40 CASES.

Background: Ventriculo -peritoneal [VP] shunt is the most commonly used cerebrospinal ?uid (CSF) diversion procedure for the management of hydrocephalus. However, when the absorption of CSF from the peritoneum is defective, it results in abdominal distension with CSF ascites. In such cases, an alternate diversion procedure - the ventriculo-atrial [VA] shunt – may be performed. However, this procedure is also associated with several perioperative problems like arrhythmias, air embolism and infection. Materials and methods: A retrospective analysis of 40 cases on the perioperative concerns of VA shunt procedures, performed in our institute, was done. Indication of the shunt, preoperative status & work -up, intraoperative adverse events & management and immediate post-operative complications were assessed. Out of the 40 patients, there were 25 male Results: s and 15 females and there were a total of 12 paediatric patients. Blocked shunt, abdominal infection and CSF ascites were common indications for VA shunt. All patients received general endotracheal anaesthesia with preoperative hypovolemia correction. Intraoperative tachycardia and arrhythmia were noted. Various Conclusion : preoperative concerns like distended abdomen and compromised respiration increase risk of VA shunt procedures. A better understanding of the underlying disease pathology and anticipation of related complications along with cautious and meticulous management can help prevent most of the complications of VA shunt procedure and thereby improve outcome

Introducción. El espacio extraperitoneal, se define como el segmento topográfico ubicado entre el peritoneo parietal internamente y la fascia transversalis externamente. Como resultado del desarrollo y consolidación de la cirugía laparoscópica, en particular de la herniorrafia inguinal por esta vía, se ha presentado un renovado y creciente interés en esta área anatómica, debido a la importancia de su conocimiento detallado en la cirugía de mínima invasión. Métodos. Se hizo una revisión narrativa de la literatura para presentar una información actualizada y detallada sobre la anatomía del espacio extraperitoneal y su importancia en diferentes procedimientos quirúrgicos realizados actualmente. Resultados. Por fuera del espacio peritoneal, se encuentran las áreas anatómicas externas al peritoneo parietal, que incluyen la preperitoneal y la retroperitoneal. Mediante la laparoscopia, se pueden localizar en estos espacios cinco triángulos anatómicos, además de la corona mortis y el triángulo supra vesical. Conclusión. El conocimiento del espacio extraperitoneal es de gran importancia para el cirujano general, teniendo en cuenta los múltiples procedimientos que requieren el abordaje de esta área topográfica

Introduction. The extraperitoneal space is defined as the topographic segment located between the parietal peritoneum internally and the fascia transversalis externally. As a result of the development and consolidation of laparoscopic surgery, particularly inguinal herniorrhaphy by this route, there has been a renewed and growing interest in this anatomical area, due to the importance of its detailed knowledge in minimally invasive surgery. Methods. A narrative review of the literature was made to present updated and detailed information on the anatomy of the extraperitoneal space and its importance in different surgical procedures currently performed. Results. Outside the peritoneal space are the anatomical areas external to the parietal peritoneum, including the preperitoneal and extraperitoneal. Using laparoscopy, five anatomical triangles, in addition to the corona mortis and the supravesical triangle, can be located in these spaces. Conclusion. Knowledge of the extraperitoneal space is of great importance for the general surgeon, taking into account the multiple procedures that require the approach of this topographic area

Existence of SARS-Cov-2 in the Peritoneal Fluid / Existência de SARS-Cov-2 no líquido peritoneal

Abstract Objective To determine the existence of SARS-CoV-2 in the peritoneal fluid to assess the risk of exposure through surgical smoke and aerosolization threatening healthcare workers during abdominal surgery. Background SARS-CoV-2 is a respiratory virus and possible ways of viral transmission are respiratory droplets, close contact, and fecal-oral route. Surgeries pose risk for healthcare workers due to the close contact with patients. Aerosolized particles may be inhaled via the leaked CO2 during laparoscopic procedures and surgical smoke produced by electrocautery. Methods All the data of 8 patients, who were tested positive for COVID-19, were collected between August 31, 2020 and April 30, 2021. Recorded clinicopathologic data included age, symptoms, radiological and laboratory findings, antiviral treatment before surgery, type of surgery and existence of the virus in the peritoneal fluid. Nasopharyngeal swab RT-PCR was used for the diagnosis. COVID-19 existence in the peritoneal fluid was determined by RT-PCR test as well. Results All 8 COVID-19 positive patients were pregnant, and surgeries were cesarean sections. 1 of the 8 patients was febrile during surgery. Also only 1 patient had pulmonary radiological findings specifically indicating COVID-19 infection. Laboratory findings were as follows: 4 of 8 had lymphopenia and all had elevated D-dimer levels. Peritoneal and amniotic fluid samples of all patients were negative for SARS-CoV-2. Conclusion SARS-CoV-2 exposure due to aerosolization or surgical fumes does not seem to be likely, provided the necessary precautions are taken.

Resumo Objetivo Determinar a existência de SARS-CoV-2 no fluido peritoneal para avaliar o risco de exposição através da fumaça cirúrgica e aerossolização que ameaçam os profissionais de saúde durante a cirurgia abdominal. Contexto O SARS-CoV-2 é um vírus respiratório e as possíveis formas de transmissão viral são gotículas respiratórias, contato próximo e rota fecal-oral. As cirurgias representam risco para os profissionais de saúde devido ao contato próximo com os pacientes. As partículas aerossolizadas podem ser inaladas através do CO2 vazado durante os procedimentos laparoscópicos e a fumaça cirúrgica produzida pela eletrocauterização. Métodos Todos os dados de 8 pacientes, que foram testados positivos para COVID-19, foram coletados entre 31 de agosto de 2020 e 30 de abril de 2021. Dados clinicopatológicos registrados incluíam idade, sintomas, achados radiológicos e laboratoriais, tratamento antiviral antes da cirurgia, tipo de cirurgia e existência do vírus no fluido peritoneal. O diagnóstico foi feito através do swab nasofaríngeo RT-PCR. A existência de COVID-19 no fluido peritoneal foi determinada pelo teste de RT-PCR também. Resultados Todas as 8 pacientes positivas para COVID-19 estavam grávidas, e as cirurgias eram cesarianas. 1 das 8 pacientes estava com febre durante a cirurgia. Também apenas 1 paciente tinha achados radiológicos pulmonares especificamente indicando infecção por COVID-19. Os achados laboratoriais foram os seguintes: 4 de 8 tinham linfopenia e todas apresentavam níveis elevados de D-dímero. Amostras de fluido peritoneal e líquido amniótico de todas as pacientes foram negativas para SARS-CoV-2. Conclusão A exposição ao SARS-CoV-2 devido à aerossolização ou fumaças cirúrgicas não parece ser provável, desde que sejam tomadas as precauções necessárias.

Caracterización clínica y microbiológica de los eventos de peritonitis asociada a diálisis peritoneal en un hospital de Chile. Un análisis retroāspectivo

Introducción: Las infecciones asociadas a diálisis peritoneal constituyen una de las causas de morbimortalidad más importante en estos pacientes y la terapia antimicrobiana empírica y dirigida adecuada es fundamental para mejorar el resultado, por lo que es importante establecer la microbiología local. Objetivo: Revisar la experiencia clínica de cinco años del Hospital Carlos Van Buren de Valparaíso, Chile, describiendo las características clínicas y microbiológicas de los pacientes con episodios de peritonitis asociada a diálisis peritoneal. Metodología De forma retrospectiva se accedió a los registros clínicos de aquellos pacientes mayores de 18 años que presentaron al menos un evento de peritonitis asociada a diálisis peritoneal. Resultados: De un total de 26 episodios, 62% de los pacientes fueron de sexo femenino, con un promedio de edad de 53 años. La principal comorbilidad fue la hipertensión arterial (100%), y el dolor abdominal fue el síntoma más frecuente (85%), con una mortalidad general de 7,7%. En el laboratorio la leucocitosis, la proteína C reactiva (PCR) y la velocidad de hemosedimentación (VHS) fueron los hallazgos más importantes. Predominaron las cocáceas grampositivas (54%), seguido de bacilos gramnegativos no fermentadores y Enterobacterales en igual proporción (11,5% cada grupo). Casos aislados de Candida albicans y Pasteurella canis fueron identificados, y en 15% de los casos el cultivo resultó negativo. Conclusión: Se pudo conocer las características clínicas y microbiológicas locales de esta patología, para así redefinir las directrices de manejo en la institución.

Background: Infections associated with peritoneal dialysis are one of the most important causes of morbidity and mortality in these patients, and adequate empirical and targeted antimicrobial therapy are essential to improve the outcome, so it is important to establish the local microbiology. Aim: To review the clinical experience of 5 years at the Carlos Van Buren Hospital in Valparaíso, Chile, in order to know the clinical and microbiological characteristics of patients with episodes of peritonitis associated with peritoneal dialysis. Methods: Retrospectively, the clinical records of those patients over 18 years of age who presented at least one peritonitis event associated with peritoneal dialysis were accessed. Results: Of a total of 26 episodes, 62% of the patients were female, with a mean age of 53 years. The main comorbidity was arterial hypertension (100%), and abdominal pain was the most frequent symptom (85%), with an overall mortality of 7.7%. In the laboratory parameters, leukocytosis, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were the most important findings. Gram-positive cocci (54%) predominated, followed by Gram-negative non-fermenting and enterobacterial bacilli in the same proportion (11.5% each group). Isolated cases of Candida albicans and Pasteurella canis were identified, and in 15% of the cases the culture was negative. Conclusion: It was possible to know the local clinical and microbiological characteristics of this pathology, in order to redefine management guidelines for our institution.

Impact of different automated peritoneal dialysis modalities on the inflammatory profile of elderly patients with chronic kidney disease / Impacto das diferentes modalidades de diálise peritoneal automatizada sobre o perfil inflamatório de idosos portadores de doença renal crônica

Abstract Introduction: Chronic kidney disease, more prevalent in the elderly, is considered a public health issue worldwide. Objective: To evaluate the impact of automated, peritoneal dialysis modalities, intermittent and continuous, on the inflammatory profile of elderly people with chronic kidney disease. Methods: Prospective, cross-sectional and analytical study carried out in a dialysis clinic in Brasília - Brazil, with 74 elderly people aged 60 years or older. The patients underwent rapid Peritoneal Equilibration Test, clinical assessment, blood collection for biochemical and cytokine assessments, interleukin 6 and transforming growth factor beta 1, and answered a quality-of-life questionnaire (KDQOL-SF36). We used a 5% significance level for data analysis, associations and correlations. Results: Patients in the continuous modality had higher serum values of transforming growth factor beta 1 than those in the intermittent modality, which had higher peritoneal transforming growth factor beta 1, age and residual renal function than those in continuous mode. Interleukin 6 dosage in the peritoneum was associated with age, while serum IL-6 was associated with IL-6 in the peritoneum, time on dialysis and age. There was no association between the modality and the presence of diabetes, blood volume or nutritional status. Both modalities enable good adaptation to the dialysis treatment. Conclusion: Inflammation in automated peritoneal dialysis is mainly associated with low residual renal function, advanced age and longer time on therapy, and not to the type of dialysis performed.

Resumo Introdução: A doença renal crônica, mais prevalente em idosos, é considerada um problema de saúde pública em todo o mundo. Objetivo: Avaliar o impacto das modalidades de diálise peritoneal automatizada, intermitente e contínua, no perfil inflamatório de idosos renais crônicos. Métodos: Estudo prospectivo, transversal e analítico realizado em uma clínica de diálise em Brasília, com 74 idosos com idade igual ou maior que 60 anos. Os pacientes foram submetidos ao Teste de Equilíbrio Peritoneal rápido, avaliação clínica, coleta de sangue para avaliações bioquímicas e de citocinas, interleucina 6 e fator de crescimento transformador beta 1, e questionário de qualidade de vida (KDQOL-SF36). Foram utilizadas para análise dos dados, associações e correlações com nível de significância de 5%. Resultados: Pacientes na modalidade contínua apresentaram valores séricos do fator de crescimento transformador beta 1 maiores do que os em modalidade intermitente. Estes apresentaram fator de crescimento transformador beta 1 no peritônio, idade e função renal residual maiores do que os em modalidade contínua. A dosagem da interleucina 6 no peritônio foi associada à idade, enquanto a IL-6 sérica foi associada à IL-6 no peritônio, ao tempo em diálise e à idade. Não houve associação entre a modalidade e a presença de diabetes, volemia ou estado nutricional. Ambas as modalidades permitem boa adequação à terapia dialítica. Conclusão: A inflamação na diálise peritoneal automatizada está associada principalmente à baixa função renal residual, à idade avançada e ao maior tempo em terapia, e não à modalidade de diálise realizada.

Infectious and mechanical complications in planned-start vs. urgent-start peritoneal dialysis: a cohort study / Complicações infecciosas e mecânicas relacionadas à diálise peritoneal de início planejado vs. não planejado: um estudo de coorte

Abstract Background: Few studies have compared the infectious and mechanical complications seen in planned-start and urgent-start peritoneal dialysis (PD) patients. Objectives: To compare the incidence and etiology of mechanical and infectious complications in patients offered planned- and urgent-start PD and assess potential differences in patient survival and time on PD. Methods: This retrospective cohort study included patients with chronic kidney disease on planned- and urgent-start PD seen from 2014 to 2020 and compared them for mechanical and infectious complications, clinical outcome, death rates, and need to switch to hemodialysis. Results: Ninety-nine patients on planned-start PD and 206 on urgent-start PD were included. Incidence of exit-site infection (18.9 vs. 17.17%, p=0.71) and peritonitis (24.27 vs. 27.27%, p=0.57) were similar between patients, while pathogens causing peritonitis were different, although non-fermenting Gram-negative bacilli were more commonly seen in the planned-start PD group. Leakage as a mechanical complication and hospitalization were more common among patients needing urgent-start PD (10.68 vs. 2.02%, p=0.0085 and 35.44 vs. 17.17%, p=0.0011, respectively). Patient survival was similar between groups. Cox regression found an association between death and age (HR=1.051, 95% CI 1.026-1.07, p=0.0001) and albumin (HR=0.66, 95% CI 0.501-0.893, p=0.0064), and between peritonitis and a diagnosis of diabetes (HR=2.016, 95% CI 1.25-3.25, p=0.004). Conclusion: Patient survival and time on PD were similar between the planned- and urgent-start PD groups, while leakage was more frequently seen in the urgent-start PD group. Death was associated with lower albumin levels and older age, while peritonitis was associated with diabetes.

Resumo Antecedentes: Poucos estudos compararam as complicações infecciosas e mecânicas relacionadas à diálise peritoneal (DP) de início planejado e não planejado. Objetivos: Comparar a incidência e etiologia das complicações mecânicas e infecciosas associadas à DP tanto de início planejado quanto não planejado e avaliar comparativamente a sobrevida da técnica e dos pacientes. Métodos: Estudo de coorte retrospectivo que avaliou pacientes com doença renal crônica em DP não planejada e planejada de 2014 a 2020 quanto às complicações mecânicas e infecciosas e desfechos clínicos óbito ou mudança para hemodiálise. Resultados: Foram avaliados 99 pacientes em DP planejada e 206 em DP não planejada. Foram semelhantes quanto à incidência de Infecção do Orifício de Saída (18,9x17,17%, p=0,71), peritonite (24,27x27,27%, p=0,57) e diferentes quanto aos agentes etiológicos das peritonites, sendo os bacilos Gram-negativos não fermentadores mais frequentes no grupo planejado. Diferiram quanto à complicação mecânica extravasamento e internação, ambas mais frequentes no grupo não planejado (10,68 x 2,02%, p=0,0085 e 35,44 x 17,17%, p=0,0011, respectivamente). Semelhantes quanto à sobrevida dos pacientes e da técnica. À regressão de Cox, associou ao óbito a idade (HR=1,051, IC 95% 1,026-1,07, p=0,0001) e a albumina (HR=0,66, IC 95% 0,501-0,893, p=0,0064), e à peritonite a presença de diabetes (HR=2,016, IC 95% 1,25-3,25, p=0,004). Conclusão: A sobrevida da técnica e dos pacientes foi semelhante nos grupos DP planejada e não planejada, enquanto o extravasamento foi mais frequente no grupo de início não planejado. Associaram-se ao óbito menores valores de albumina e maior idade, e à peritonite, o diabetes.
