ABSTRACT

Resumen Rothia mucilaginosa es una bacteria propia de la microbiota del tracto respiratorio superior, que se asocia en forma infrecuente a infecciones en pacientes inmunocomprometidos y con enfermedades pulmonares crónicas, principalmente neumonía y bacteriemia. Su tratamiento generalmente, se basa en el uso de antibacterianos β lactámicos. Se describe el caso de un paciente sometido a un trasplante renal con uso de fármacos inmunosupresores, que cursó con una infección diseminada por Cryptococcus neoformans. Tras el inicio de la terapia antifúngica, presentó un cuadro febril, con aparición de nuevos infiltrados radiológicos e insuficiencia respiratoria aguda, demostrándose en el estudio con lavado broncoalveolar, un cultivo positivo para R. mucilaginosa, descartándose otras etiologías. Evolucionó en forma favorable tras el uso de meropenem, con buena respuesta clínica y resolución de los infiltrados radiológicos.


Abstract Rothia mucilaginosa is a bacterium derived from the upper respiratory tract microbiota, which is rarely associated with infections in immunocompromised patients suffering chronic lung diseases, mainly pneumonia and bacteremia. Its treatment is generally based on the use of β-lactams. The case study of a kidney transplant patient using immunosuppressive drugs, who developed a disseminated Cryptococcus neoformans infection, is described. After starting antifungal therapy, he presented with fever, appearance of new radiological infiltrates and acute respiratory failure, demonstrating a positive culture for R. mucilaginosa in a study with bronchoalveolar lavage, ruling out other etiologies. He evolved favorably after the use of meropenem, with good clinical response and resolution of radiological infiltrates.

ABSTRACT

OBJECTIVES@#After renal transplantation, patients need to take various immunosuppressant, but the drug compliance is poor. The theory of planned behavior suggests that the past medication behavior and subjective norms of individuals are closely related to medication compliance. This study aims to explore the change of medication compliance behavior and its influenting factors for renal transplantation patients at different stages.@*METHODS@#This study was a prospective longitudinal study. The Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS), Medication Belief Scale, Social Support Scale and Quality of Life Scale were used to dynamically follow up renal transplantation patients at pre-operation and 1-month, 6-month, and 12-month after transplantation.@*RESULTS@#A total of 300 patients completed the whole follow-up. The percentage of patients with good medication compliance was 97.60%, 87.30% and 84.30% at 1-month, 6-month and 12-month after transplantation respectively. The life quality of the patients was decreased at 6 months after the operation, and the patients with better self-reported life quality had poor medication compliance. After adjusting for demographic data, the risk of medication incompliance in patients with poor medication compliance before operation was 37.646 times than those with good compliance. Patients who did not use medication reminders had high risk (odds ratio=2.467) of drug non-adherence. The risk of drug non-adherence in patients with more postoperative misgivings was 1.265 times compared with that in patients with less postoperative misgivings.@*CONCLUSIONS@#The medication compliance decreases with the time of transplantation, but the medication compliance of patients with good self-reported life quality is poor. Medication concerns reduce the compliance behavior. Preoperative medication behavior has a significant predictive effect on postoperative behavior. Medication reminder is a protective factor for promoting compliance. Medical staff should pay more attention to preoperative medication belief, behaviors and reminder of using drug so as to provide precise intervention in the renal transplantation patients.

ABSTRACT

Las complicaciones cardiovasculares representan la principal causa de morbilidad y mortalidad en pacientes con enfermedad renal crónica, por lo que el objetivo de este artículo es demostrar la influencia de la permanencia de la fístula arteriovenosa sobre variables eco cardiográficamente mensuradas en el corazón izquierdo. Para ello, se definió un estudio multivariable, longitudinal, prospectivo y controlado de grupos independientes después de una intervención que incluyó 39 pacientes a los que se le cerró el angioacceso (grupo de estudio) y 42 que no fueron expuestos a la cirugía (grupo control). Ambos grupos exhibían trasplante renal funcionante. Los principales resultados surgenal comparar el predominio entre el grupo de estudio con el de control, la edad promedio; 45,6 y 44,1 años, el sexo masculino, 24 (60%) y 23 (53,5%) y el color de la piel blanca; 33 (82,5%) y 32 (74,4%). La etiología de la nefropatía originaria más frecuente fue la nefropatía vascular hipertensiva; 12 (30%) vs 14 (32,6%). Entre las manifestaciones clínicas, en el grupo de estudio se evidenció remisión de las palpitaciones y la disnea de esfuerzo. Respecto a la tensión arterial, para la sistólica oscilaba; de 123 ±13,4 a 120,5 ±9,2 vs de 125,6 ±8,4 a 128 ±8,3 mm Hg (p= 0,000), mientras la diastólica variaba de; 76,8 ±7,5 a 76,3 ±6,2 vs 78,6 ±4,9 a 82,4 ±3,9 mm Hg (p= 0,000). El hematocrito comportaba valores equivalentes; 0,43 ±0,06 y 0,45 ±0,06 vs 0,42 ±0,05 y 0,42 ±0,06 l/l (p= 0,035) y la creatinina sérica mostró descenso en los pacientes intervenidos de; 106,8 ± 26,2 hasta 99,8 ±23,9 µ Mol/l vs 114 ±27,8 a 120,3 ±31 µ Mol/l (p= 0,002). Las variables ecocardiográficas mensuradas comparativamente según la localización de los angioaccesos a nivel del codo izquierdo; diámetro del ventrículo izquierdo: 3,12 ±4,08 vs 1,48 ±3,46 mms (p=0,001), fracción de eyección del ventrículo izquierdo: 2,99 ±5,47 vs -1,98 ±6,23 % (p=0,018) y el volumen telediastólico: -23 ±33,41 vs 10,86 ±36,87 ml (p=0,006). El codo contralateral revelaba; para la fracción de eyección del ventrículo izquierdo: 3,32 ±3,42 vs -2,18 ±4,78 % (p=0,037) y para el gasto cardíaco: -1,29 ±0,88 vs -0,26 ±0,86 l/min (0,020). Las conclusiones demuestran que el cierre del angioacceso a pacientes con trasplante renal funcionante respecto a los no intervenidos, contribuye a la regresión de las alteraciones morfológicas y hemodinámicas constatadas por ecocardiografía transtorácica en el corazón izquierdo a nivel de las diferentes localizaciones de los accesos vasculares.


Cardiovascular complications represent the main cause of morbidity and mortality in patients with chronic renal disease, so the objective of this article is to demonstrate the influence of the patency of the arteriovenous fistula on echocardiographic variables measured in the left heart. For this, a multivariate study, longitudinal, prospective and controlled study of independent groups after an intervention that included 39 patients who had their angioaccess closed (study group) and 42 who were not exposed to surgery (control group). Both groups exhibited functional kidney transplantation. The main results emerge when comparing the prevalence between the study group and the control group, the average age; 45.6 and 44.1 years, the male sex, 24 (60%) and 23 (53.5%) and the white skin color; 33 (82.5%) and 32 (74.4%). The most frequent etiology of the original nephropathy was hypertensive vascular nephropathy; 12 (30%) vs 14 (32.6%). Among the clinical manifestations, remission of palpitations and dyspnea on exertion were evidenced in the study group. With regard to blood pressure, for the systolic it ranged from 123 ±13.4 to 120.5 ±9.2 vs. 125.6 ±8.4 to 128 ±8.3 mmHg (p= 0.000), while the diastolic varied from; 76.8 ±7.5 to 76.3 ±6.2 vs. 78.6 ±4.9 to 82.4 ±3.9 mmHg (p= 0.000). The hematocrit had equivalent values; 0.43 ±0.06 and 0.45 ±0.06 vs 0.42 ±0.05 and 0.42 ±0.06 l/l (p= 0.035) and the serum creatinine showed decrease in the operated patients from; 106.8 ±26.2 to 99.8 ±23.9 µMol/l vs 114 ±27.8 to 120.3 ±31 µMol/l (p= 0.002). The echocardiographic variables measured comparatively according to the location of the angioaccesses at the left elbow level; diameter of the left ventricle: 3.12 ±4.08 vs 1.48 ±3.46 mms (p=0.001), ejection fraction of the left ventricle: 2.99 ±5.47 vs -1.98 ±6.23 % (p=0.018) and the telediasolic volume: -23 ±33.41 vs 10.86 ±36.87 ml (p=0.006). The contralateral elbow revealed; for the left ventricular ejection fraction: 3.32 ±3.42 vs -2.18 ±4.78 % (p=0.037) and for cardiac output: -1.29 ±0.88 vs -0.26 ±0.86 l/min (0.020). The conclusions show that the our study has shown that closing the angioaccess to patients with functioning renal transplants with respect to those not operated, contributes to the regression of morphological and hemodynamic alterations observed by transthoracic echocardiography in the left heart at the different locations of the vascular accesses.

ABSTRACT

Resumo Os aneurismas de aorta abdominal (AAA) são os mais frequentes, mesmo quando comparados a outros segmentos da aorta. A prevalência e a história natural de aneurismas arteriais em receptores de transplante de órgão abdominal permanecem incertas. Relatamos a abordagem de um caso de aneurisma de aorta abdominal em um paciente transplantado renal e com alergia ao contraste. Foi realizado o tratamento convencional do aneurisma de aorta abdominal com um by-pass aorto bi-ilíaco. Para manutenção do enxerto renal, foi confeccionado um by-pass temporário da artéria axilar direita até a artéria ilíaca comum direita. O paciente foi encaminhado para a unidade de terapia intensiva, onde permaneceu estável hemodinamicamente e recebeu alta no 2º pós-operatório. A cirurgia convencional aberta com derivação extra-anatômica temporária é uma alternativa para o tratamento do AAA em pacientes com transplante renal.


Abstract Abdominal aortic aneurysms (AAA) are the most common type, even when compared to those involving other segments of the aorta. The prevalence and natural history of arterial aneurysms in abdominal organ transplant recipients remain uncertain. We report a case of abdominal aortic aneurysm in a kidney transplant patient with contrast allergy. Conventional abdominal aortic aneurysm repair was performed, constructing a bi-iliac aortic bypass. A temporary bypass was constructed from the right axillary artery to the right common iliac artery to maintain the renal graft. The patient was transferred to the intensive care unit, where he remained hemodynamically stable, and he was discharged on the 2nd postoperative day. Conventional open surgery with temporary extra-anatomic bypass is an alternative option for treatment of AAA in patients with transplanted kidneys.

ABSTRACT

Resumo: Este estudo avaliou a prevalência e os fatores associados a não procura por transplante renal entre pacientes em diálise crônica na Região Metropolitana de Fortaleza, Ceará, Brasil. Foram excluídos os pacientes sem condições clínicas e aqueles em avaliação pré-transplante renal. Um questionário semiestruturado foi aplicado, incluindo opções para a pergunta "Qual o principal motivo pelo qual o senhor/senhora não está inscrito(a) para o transplante renal?". A prevalência de pacientes considerados aptos, mas não inscritos e nem em avaliação pré-transplante renal foi de 50,7%. As principais causas foram: receio de insucesso/perda do enxerto (32,5%), dificuldade de transporte e acesso aos exames (20,9%) e problemas pessoais ou familiares temporários (13,7%). Em análise múltipla, as variáveis associadas a risco de receio do insucesso/perda do enxerto foram: sexo feminino (OR = 1,763; IC95%: 1,224-2,540) e doença renal dialítica (DRC 5-D) por hipertensão (OR = 1,732; IC95%: 1,178-2,547), tendo a renda mensal (salários mínimos) uma associação de proteção (OR = 0,882; IC95%: 0,785-0,991). O tempo em diálise (meses) foi um fator de risco para a dificuldade de transporte e acesso aos exames (OR = 1,004; IC95%: 1,001-1,007) e o sexo feminino apresentou uma associação de proteção (OR = 0,576; IC95%: 0,368-0,901). Esses resultados mostram elevada prevalência de pacientes em diálise fora de lista para transplante renal. As principais causas são reflexo da desinformação e falta de acesso. Sexo feminino, baixa renda e DRC 5-D por hipertensão foram os fatores de risco para a não procura por transplante renal por receio de perda do enxerto, reflexo da carência de informações sobre a modalidade. Sexo masculino e maior tempo em diálise foram os fatores de risco para a dificuldade de acesso à terapia.


Abstract: This study evaluated the prevalence and factors associated with lack of enrollment for kidney transplant among patients in chronic dialysis in Greater Metropolitan Fortaleza, Ceará, Brazil. The sample excluded patients with insufficient clinical status and those already in pre-kidney transplant evaluation. A semi-structured questionnaire was applied, including options for the question, "What is the main reason why you are not enrolled for kidney transplant?" Prevalence of patients considered fit but not enrolled or in pre- kidney transplant evaluation was 50.7%. The main reasons were fear of failure/loss of grafting (32.5%), difficulty with transportation or access to tests (20.9%), and temporary personal or family problems (13.7%). In the multivariate analysis, the variables associated with fear of failure or loss of graft were female sex (OR = 1.763; 95%CI: 1.224-2.540) and end-stage renal disease (ESRD) due to hypertension (OR = 1.732; 95%CI: 1.178-2.547), while monthly income (number of minimum wages) showed a protective association (OR = 0.882; 95%CI: 0.785-0.991). Time on dialysis (months) was a risk factor for difficulty with transportation and access to tests (OR = 1.004; 95%CI: 1.001-1.007), and female sex showed a protective association (OR = 0.576; 95%CI: 0.368-0.901). These results show high prevalence of patients in dialysis not enrolled on the kidney transplant waitlist. The main causes were lack of information and lack of access. Female sex, low income, and ESRD due to hypertension were risk factors for lack of enrollment on the kidney transplant waitlist due to fear of loss of graft, resulting from lack of information on this treatment modality. Male sex and longer time on dialysis were risk factors for difficulty in access to kidney transplant.


Resumen: Este estudio evalúo la prevalencia y los factores asociados a la no búsqueda de un trasplante renal entre pacientes con diálisis crónica en la Región Metropolitana de Fortaleza, Ceará, Brasil. Se excluyeron a pacientes sin condiciones clínicas y aquellos en evaluación pre-trasplante renal . Se aplicó un cuestionario semiestructurado, incluyendo opciones a la pregunta "¿cuál es el principal motivo por el cual usted no está inscrito(a) para un trasplante renal?" La prevalencia de pacientes considerados aptos, pero no inscritos y ni en evaluación pre-trasplante renal fue de un 50,7%. Las principales causas fueron: recelo al fracaso/pérdida del injerto (32,5%), dificultad de transporte y acceso a los exámenes (20,9%), así como problemas personales o familiares temporales (13,7%). En el análisis múltiple, las variables asociadas al riesgo del recelo al fracaso/pérdida del injerto fueron de sexo femenino (OR = 1,763; IC95%: 1,224-2,540) y enfermedad renal dialítica (DRC 5-D) por hipertensión (OR = 1,732; IC95%: 1,178-2,547), teniendo la renta mensual (salarios mínimos) una asociación de protección (OR = 0,882; IC95%: 0,785-0,991). El tiempo en diálisis (meses) fue un factor de riesgo para la dificultad en el transporte y acceso a los exámenes (OR = 1,004; IC95%: 1,001-1,007), y el sexo femenino tuvo una asociación de protección (OR = 0,576; IC95%: 0,368-0,901). Estos resultados muestran la elevada prevalencia de pacientes en diálisis fuera de la lista para transplante renal. Las principales causas son reflejo de la desinformación y falta de acceso. Sexo femenino, baja renta y DRC 5-D por hipertensión fueron factores de riesgo para la no búsqueda de trasplante renal por recelo a la pérdida del injerto, reflejo de la carencia de información sobre la modalidad. Sexo masculino y mayor tiempo en diálisis fueron factores de riesgo para la dificultad de acceso a la terapia. izará la atención a las vulnerabilidades individuales desde la perspectiva de la salud integral.

ABSTRACT

Abstract Renal transplant remains the preferred therapy for end-stage renal disease (ESRD). Given the shortage of suitable donor kidneys, use of an expanded criteria donor (ECD) allows marginal kidneys to be transplanted; albeit at risk of increased graft failure due to lower nephron mass. To reduce the risk of graft failure, double kidney transplant (DKT) is advocated, with favorable outcomes. Transplant renal artery stenosis (TRAS) is one of the most common vascular complications following renal transplant. Unlike single kidney transplants, where TRAS usually presents with fluid overload, uncontrolled hypertension, and worsening kidney functions; it may be clinically silent in DKT patients since they have two functional transplanted kidneys. We hereby report a case of TRAS in a DKT patient who had 2 years of favorable clinical outcomes following successful endovascular stenting. He however recently died of COVID-19 associated pneumonitis.


Resumo O transplante renal continua sendo a terapia preferida para doenças renais em fase terminal. Dada a escassez de rins de doadores adequados, o doador com critérios expandidos permite que rins marginais sejam transplantados, embora haja um maior risco de falha do enxerto devido à diminuição da massa nefrótica. Para diminuir o risco de falha do enxerto, recomenda-se o transplante renal duplo (TRD), com resultados favoráveis. A estenose de artéria renal transplantada (EART) é uma das complicações vasculares mais comuns após o transplante renal. Ao contrário dos transplantes de rim simples, nos quais a EART geralmente se manifesta como sobrecarga de fluido, hipertensão descontrolada e piora das funções renais, ela pode ser clinicamente silenciosa em pacientes com TRD, pois eles têm dois rins funcionais transplantados. Relatamos aqui um caso de EART em um paciente com TRD que teve resultados clínicos favoráveis por dois anos após o sucesso do implante de stent endovascular. No entanto, ele morreu recentemente de pneumonite associada à covid-19.

ABSTRACT

Abstract Various vascular complications following renal transplantation include renal artery and vein thrombosis, renal artery stenosis, pseudoaneurysm, and iliac artery dissection. Transplant renal artery stenosis (TRAS) is the most common, while iliac artery dissection is the rarest of these various vascular complications. We describe an elderly male, who had both external iliac artery dissection and TRAS at 2 months following renal transplantation. He underwent successful percutaneous endovascular intervention of both complications. The post-intervention course was uneventful, with improvement in graft renal functions and left lower limb perfusion.


Resumo As diversas complicações vasculares possíveis após um transplante renal incluem trombose da veia e artéria renais, estenose da artéria renal, pseudoaneurisma e dissecção da artéria ilíaca. Entre essas diversas complicações, a estenose da artéria renal transplantada é a mais comum, enquanto a dissecção da artéria ilíaca é a mais rara. Relatamos o caso de um homem idoso que desenvolveu tanto dissecção da artéria ilíaca quanto estenose da artéria renal transplantada 2 meses após transplante renal. As intervenções endovasculares percutâneas foram bem-sucedidas em ambas as complicações. O período pós-intervenção cursou sem complicações, com melhora na função renal do enxerto e na perfusão do membro inferior esquerdo.

ABSTRACT

Hypercalcemia is common in patients after kidney transplantation (KTx) and is associated with persistent hyperparathyroidism in the majority of cases. This retrospective, single-center study evaluated the prevalence of hypercalcemia after KTx. KTx recipients were evaluated for 7 years after receiving kidneys from living or deceased donors. A total of 301 patients were evaluated; 67 patients had hypercalcemia at some point during the follow-up period. The median follow-up time for all 67 patients was 62 months (44; 80). Overall, 45 cases of hypercalcemia were classified as related to persistent post-transplant hyperparathyroidism (group A), 16 were classified as "transient post-transplant hypercalcemia" (group B), and 3 had causes secondary to other diseases (1 related to tuberculosis, 1 related to histoplasmosis, and 1 related to lymphoma). The other 3 patients had hypercalcemia of unknown etiology, which is still under investigation. In group A, the onset of hypercalcemia after KTx was not significantly different from that of the other groups, but the median duration of hypercalcemia in group A was 25 months (12.5; 53), longer than in group B, where the median duration of hypercalcemia was only 12 months (10; 15) (P<0.002). The median parathyroid hormone blood levels around 12 months after KTx were 210 pg/mL (141; 352) in group A and 72.5 pg/mL (54; 95) in group B (P<0.0001). Hypercalcemia post-KTx is not infrequent and its prevalence in this center was 22.2%. Persistent hyperparathyroidism was the most frequent cause, but other important etiologies must not be forgotten, especially granulomatous diseases and malignancies.

ABSTRACT

Abstract Reactivation of chronic Trypanosoma cruzi infection in solid organ transplant recipients (SOTRs) has been reported. The patient presented with a 2-week history of two painful erythematous, infiltrated plaques with central ulceration and necrotic crust on the left thigh. She had a history of chronic indeterminate Chagas disease (CD) and had received a kidney transplant before 2 months. Skin biopsies revealed lobular panniculitis with intracellular amastigote forms of T. cruzi. The patient was diagnosed with CD reactivation. Treatment with benznidazole significantly improved her condition. CD reactivation should be suspected in SOTRs living in endemic areas with clinical polymorphism of skin lesions.

ABSTRACT

OBJECTIVES@#Urinary tract infection (UTI) is the most common infection complication after kidney transplantation, and the reports of the incidence vary greatly among different centers. This study aims to explore the risk factors for UTI after kidney transplantation with the donation from brain death (DBD) and the impact on graft function, thus to provide theoretical basis for comprehensive prevention and treatment of UTI after kidney transplantation.@*METHODS@#The clinical and laboratory data of DBD kidney transplantation from January 2017 to December 2018 in Xiangya Hospital, Central South University were collected and retrospectively analyzed. Patients were assigned into an UTI group and a non-UTI group. The base line characteristics, post-transplant complications, and graft function were compared between the 2 groups. Multivariate logistic regression was used to analyze the risk factors for UTI.@*RESULTS@#A total of 212 DBD kidney transplant recipients were enrolled in this study. UTI occurred in 44 (20.75%) patients after transplantation. The female, the time of indwelling catheter, and postoperative urinary fistula were independent risk factors for UTI after DBD kidney transplantation. A total of 19 strains of gram-positive bacteria, 12 strains of gram-negative bacteria , and 10 strains of fungi were isolated from the urine of 44 UTI patients. The UTI after kidney transplantation significantly increased time of hospital stay (@*CONCLUSIONS@#UTI after DBD kidney transplantation transplantation affects the renal function at 3 months and increases the patient's economic burden.

ABSTRACT

With the continuous development of kidney transplantation technique, the survival time after kidney transplantation is gradually prolonged. Thus, the malignant tumor has been the important influencing factor on the long-term survival for kidney transplantation patients. Renal cell carcinoma is a relatively common tumor after kidney transplantation. Besides, clear cell renal cell carcinoma and papillary renal cell carcinoma are the relatively common pathological types for renal cell carcinoma following kidney transplantation. However, bilateral renal cell carcinoma following kidney transplantation is comparatively rare. In this article, we presented a case of bilateral papillary renal cell carcinoma, which occurred after kidney transplantation. And the diagnosis and treatment were introduced in detail. The patient was 37 years old, and he underwent kidney transplantation 13 years ago in our hospital, because of kidney failure. After kidney transplantation, he had regular medical check-up every year. In this year, his urological ultrasound results indicated bilateral renal tumors. And then, he received abdominal and pelvic computed tomography, and the result also showed bilateral renal tumors, which were likely to be malignant tumors. After adequate consultation, the patient chose surgical treatment. The patient received long-term immunosuppressive therapy, because of kidney transplantation. Considering this, the surgeon decided to choose a staging surgical treatment, in order to reduce the bad influence of one-stage surgery. Then, the patient first underwent retroperitoneal laparoscopic radical nephrectomy for right renal tumor in our hospital, and he had no complications after operation. The pathological results showed papillary renal cell carcinoma. He was discharged successfully. He underwent retroperitoneal laparoscopic radical nephrectomy for left renal tumor in our hospital one month later, and he had no complications after operation. The pathological results also showed papillary renal cell carcinoma. He was discharged successfully two days after surgery. In the 3-month follow-up, the patient was recovering well. To sum up, the incidence of bilateral renal cell carcinoma following kidney transplantation is relatively rare, and bilateral radical nephrectomy is effective and safe treatment. Above all, it is the patient's condition that determines the choice of staging surgery or simultaneous surgery.

ABSTRACT

BACKGROUND@#Delayed graft function (DGF) is the main cause of renal function failure after kidney transplantation. This study aims at investigating the value of hypothermic machine perfusion (HMP) parameters combined with perfusate biomarkers on predicting DGF and the time of renal function recovery after deceased donor (DD) kidney transplantation.@*METHODS@#HMP parameters, perfusate biomarkers and baseline characteristics of 113 DD kidney transplantations from January 1, 2019 to August 31, 2019 in the First Affiliated Hospital of Xi'an Jiaotong University were retrospectively analyzed using univariate and multivariate logistic regression analysis.@*RESULTS@#In this study, the DGF incidence was 17.7% (20/113); The multivariate logistic regression results showed that terminal resistance (OR: 1.879, 95% CI 1.145-3.56) and glutathione S-transferase (GST)(OR = 1.62, 95% CI 1.23-2.46) were risk factors for DGF; The Cox model analysis indicated that terminal resistance was an independent hazard factor for renal function recovery time (HR = 0.823, 95% CI 0.735-0.981). The model combining terminal resistance and GST (AUC = 0.888, 95% CI: 0.842-0.933) significantly improved the DGF predictability compared with the use of terminal resistance (AUC = 0.756, 95% CI 0.693-0.818) or GST alone (AUC = 0.729, 95% CI 0.591-0.806).@*CONCLUSION@#According to the factors analyzed in this study, the combination of HMP parameters and perfusate biomarkers displays a potent DGF predictive value.

ABSTRACT

BACKGROUND@#The complement system plays an important role in the immune response to transplantation, and the diagnostic significance of peritubular capillary (PTC) C4d deposition (C4d+) in grafts is controversial. The study aimed to fully investigate the risk factors for PTC C4d+ and analyze its significance in biopsy pathology of kidney transplantation.@*METHODS@#This retrospective study included 124 cases of kidney transplant with graft biopsy and donor-specific antibody (DSA) testing from January 2017 to December 2019 in a single center. The effects of recipient pathological indicators, eplet mismatch (MM), and DSAs on PTC C4d+ were examined using univariate and multivariate logistic regression analyses.@*RESULTS@#In total, 35/124 (28%) were PTC C4d+, including 21 with antibody-mediated rejection (AMR), eight with renal tubular injury, three with T cell-mediated rejection, one with glomerular disease, and two others. Univariate analysis revealed that DSAs (P < 0.001), glomerulitis (P < 0.001), peritubular capillaritis (P < 0.001), and human leukocyte antigen (HLA) B eplet MM (P = 0.010) were the influencing factors of PTC C4d+. According to multivariate analysis, DSAs (odds ratio [OR]: 9.608, 95% confidence interval [CI]: 2.742-33.668, P < 0.001), glomerulitis (OR: 3.581, 95%CI: 1.246-10.289, P = 0.018), and HLA B eplet MM (OR: 1.166, 95%CI: 1.005-1.353, P = 0.042) were the independent risk factors for PTC C4d+. In receiver operating characteristic curve analysis, the area under the curve was increased to 0.831 for predicting PTC C4d+ when considering glomerulitis, DSAs, and HLA B eplet MM. The proportions of HLA I DSAs and PTC C4d+ in active antibody-mediated rejection were 12/17 and 15/17, respectively; the proportions of HLA class II DSAs and PTC C4d+ in chronic AMR were 8/12 and 7/12, respectively. Furthermore, the higher the PTC C4d+ score was, the more serious the urinary occult blood and proteinuria of recipients at the time of biopsy.@*CONCLUSIONS@#PTC C4d+ was mainly observed in AMR cases. DSAs, glomerulitis, and HLA B eplet MM are the independent risk factors for PTC C4d+.

ABSTRACT

Abstract Infections are frequent complications of kidney transplants. We aimed at determining the frequency and type of infections that occur in renal transplant recipients during the early (0-1 month), intermediate (1-6 months) and late (6-12 months) post-transplant period and analyzing the risk factors for infection. To this aim, we conducted a retrospective cohort study on 1-year post-transplant follow-up in two third-level university hospitals in Cordoba city. All consecutive recipients of renal transplants performed between 2009 and 2015 were included, except those with multiple solid organ transplantation and pediatric patients. We included 375 recipients, of which 235 (62.7%) had at least one episode of infection during follow-up. There were 504 episodes of infection, of which 131 (26%) occurred in the early, 272 (53.9%) in the intermediate, and 101 (20.1%) in the late post-transplant period. The most frequent infections in all periods were caused by bacteria (mainly urinary tract infections), and the most frequent viral infection was caused by Cytomegalovirus (mainly in the second and third period). In the multivariate analysis, infection risk factors were: age > 60 years (adjusted odds ratio [aOR] = 1.92; 95% CI = 1.05-3.49), organ transplantation from deceased donor (aOR = 8.19; 95% CI = 2.32-28.9), use of pigtail catheter for urinary tract drainage (aOR = 4.06; 95% CI = 1.27-12.9), and number of days in hospital after transplant (aOR = 1.05; 95% CI = 1.01-1.11). In conclusion, infections in renal transplant recipients represent a very frequent health problem in our hospitals. Understanding the local epidemiology of infection and the potential risk factors for infection acquires utmost importance.


Resumen Las infecciones son complicaciones frecuentes de los trasplantes renales. Los objetivos del estudio fueron determinar la frecuencia y el tipo de infecciones que ocurren en el período post-trasplante temprano (0-1 mes), intermedio (1-6 meses) y tardío (6-12 meses) en nuestro medio y analizar los factores de riesgo de infección. Se realizó un estudio de cohorte retrospectivo que incluyó todos los pacientes con trasplantes renales realizados entre 2009 y 2015 en dos hospitales universitarios de tercer nivel de la ciudad de Córdoba, excluidos los receptores de trasplante simultáneo de múltiples órganos sólidos y los menores de 18 años. Fueron incluidos 375 pacientes, de los cuales 235 (62.7%) tuvieron al menos un episodio de infección. Hubo 504 episodios de infección: 131 (26%) ocurrieron en el período temprano, 272 (53.9%) en el intermedio y 101 (20.1%) en el tardío. La mayoría de las infecciones fueron de origen bacteriano (principalmente del tracto urinario). La mayoría de las infecciones virales ocurrieron en el segundo y el tercer período y Citomegalovirus fue el responsable más frecuente. En el análisis multivariado, los factores de riesgo de infección post-transplante renal fueron: edad > 60 años (odds ratio ajustado [aOR] 1.92; IC95% 1.05-3.49), donante cadavérico (aOR 8.19; IC95% 2.32-28.9), uso de catéter pigtail (aOR 4.06; IC95% 1.27-12.9) y número de días internado postrasplante (aOR 1.05; IC95% 1.01-1.11). En conclusión, confirmamos que las infecciones en pacientes con trasplante renal son muy frecuentes en nuestro medio, por lo cual es importante conocer la epidemiología local y los factores de riesgo.

ABSTRACT

Las mujeres con trasplante renal (TR) suelen cursar un embarazo de alto riesgo, pues son más susceptibles a presentar complicaciones médicas. Aunado a este hecho pueden presentar alteraciones en su estado emocional y psicológico durante y después del embarazo, lo que impactaría directamente en el estilo de crianza y desarrollo posterior del niño. Se desconoce cómo son los estilos de crianza en los hijos de las mujeres con TR y el posible impacto en su funcionamiento cognoscitivo. El presente trabajo tuvo dos objetivos: 1) determinar si existían diferencias en los estilos de crianza y las funciones cognoscitivas de los hijos de mujeres con trasplante renal en comparación con los hijos de mujeres sanas y 2) identificar la asociación entre las variables asociadas al riesgo en el embarazo y los estilos de crianza con las funciones cognoscitivas. Para ello fueron reclutados de diversos centros de trasplantes 23 niños (9 casos y 14 controles) de 7-15 años con sus respectivas madres a quienes se evaluó mediante el WISC-IV y el cuestionario CRPBI. Las madres fueron evaluadas con el cuestionario BRIEF, el cuestionario PCRI-M y el BDI-II. Se realizó un diseño transversal con alcance correlacional. No se encontraron diferencias entre el grupo caso y control en los estilos de crianza ni en las funciones cognoscitivas. Sin embargo, sí se encontró asociación entre los estilos de crianza y las funciones cognoscitivas. Un estilo en el que predomine la comunicación y la disciplina se asocia con mejores resultados cognoscitivos y conductuales.


Pregnancy in Kidney Transplant (KT) recipients is usually considered of high risk. KT recipients are susceptible to have obstetric complications. Studies report that KT recipients are at higher risk of experiencing distress during and after pregnancy, situation that may have an impact in parenting styles and child's development. Characteristics of parenting styles in KT recipients' offspring and its possible impact in cognitive functions remain unknown. The aims of the study were: 1) to determine if there are differences in parenting styles and cognitive functions among KT recipients' offspring and healthy women's offspring, and 2) to identify associations between high risk pregnancy variables, parenting styles and cognitive functions. Twenty-three children (9 cases and 14 controls) aged 8-15 years and their mothers were assessed with the (WISC-V) and the CRPBI. Mothers were asked to complete BRIEF, PCRI-M, BDI-II and a socioeconomic status instrument. A transversal correlational design was performed. No differences were found between case and control group in parenting styles or cognitive functions. However, an association between parenting styles and cognitive functions was found. Being raised with communication and discipline is associated with increased cognitive results.

ABSTRACT

Introducción: Las complicaciones cardiovasculares constituyen la primera causa de morbilidad y mortalidad en el receptor de trasplante renal. Objetivo: Caracterizar la repercusión de la fístula arteriovenosa sobre variables hemodinámicas del corazón derecho en trasplante renal. Métodos: Estudio prospectivo, longitudinal. Se incluyeron 52 pacientes, evaluados clínica y ecocardiográficamente. Se compararon cinco variables hemodinámicas en el corazón derecho, previos y seis meses posteriores al cierre de la fístula arteriovenosa. Resultados: La edad promedio 46,02 años, 29 masculinos (55,8 por ciento). El diámetro de la aurícula derecha en las fístulas cerradas en la muñeca izquierda 8805; 6 años disminuyó (p=0,044), al igual que en el ventrículo derecho <6 años a nivel del pliegue del codo izquierdo (p=0,004). La presión sistólica de la arteria pulmonar descendió tras el cierre en el codo izquierdo lt;6 años (p=0,002), en las 8805;6 (p=0,05) y en el derecho (p=0,006). La presión media de la arteria pulmonar se redujo en las cerradas en pliegue del codo izquierdo <6 años (p=0,001) y 8805;6 años (p=0,017) al igual que en el derecho (p=0,009). La fracción de eyección del ventrículo derecho se incrementó al cierre en muñeca izquierda ;6 años (p=0,046) y en el codo derecho 8805;6 años (p=0,027). Conclusiones: La permanencia de la fístula arteriovenosa en el receptor de trasplante renal contribuye a la perpetuación y progresión de la disfunción cardiovascular preexistente(AU)


Introduction: Cardiovascular complications are the leading cause of morbidity and mortality in kidney transplant recipients. Objective: To describe the consequence of arteriovenous fistula on hemodynamic variables of the right heart in kidney transplantation. Methods: We conducted a prospective, longitudinal study. Fifty two patients were included, and they were clinically and echocardiographically assessed. Five hemodynamic variables were compared in the right heart, prior to the closure of the arteriovenous fistula and six months after. Results: The average age was 46.02 years, 29 were male (55.8 percent). The diameter decreased in the right atrium in closed fistulas in the left wrist #8805; 6 years (p = 0.044). The same occurred in the right ventricle <6 years at the level of the left elbow crease (p = 0.004). The systolic pressure of the pulmonary artery decreased after closure in the left elbow <6 years (p = 0.002), in ≥6 (p = 0.05) and in the right (p = 0.006). The mean pressure of the pulmonary artery was reduced in those closed in the crease of the left elbow <6 years (p = 0.001) and ≥6 years (p = 0.017) as well as in the right (p = 0.009). The right ventricular ejection fraction increased at closure in the left wrist <6 years (p = 0.046) and in the right elbow ≥6 years (p = 0.027). Conclusions: The permanence of arteriovenous fistula in the kidney transplant recipient contributes to the perpetuation and progression of the pre-existing cardiovascular dysfunction(AU)

ABSTRACT

ABSTRACT Background: Persistent hyperparathyroidism post-transplant is associated with increases in the incidence of cardiovascular events, fractures, and deaths. The aim of this study was to compare both therapeutic options available: parathyroidectomy (PTX) and the calcimimetic agent cinacalcet. Methods: A single center retrospective study including adult renal transplant recipients who developed hypercalcemia due to persistent hyperparathyroidism. Inclusion criteria: PTH > 65 pg/mL with serum calcium > 11.5 mg/dL at any time after transplant or serum calcium persistently higher than 10.2 mg/dL one year after transplant. Patients treated with cinacalcet (n=46) were compared to patients treated with parathyroidectomy (n=30). Follow-up period was one year. Clinical and laboratory data were analyzed to compare efficacy and safety of both therapeutic modalities. Results: PTX controlled calcemia faster (month 1 x month 6) and reached significantly lower levels at month 12 (9.1±1.2 vs 9.7±0.8 mg/dL, p < 0.05); PTX patients showed significantly higher levels of serum phosphate (3.8±1.0 vs 2.9±0.5 mg/dL, p < 0.05) and returned PTH to normal levels (45±51 pg/mL). Cinacalcet, despite controlling calcium and phosphate in the long term, decreased but did not correct PTH (197±97 pg/mL). The proportion of patients that remained with PTH above normal range was 95% in the cinacalcet group and 22% in the PTX group. Patients treated with cinacalcet had better renal function (creatinine 1.2±0.3 vs 1.7±0.7 mg/dL, p < 0.05). Conclusions: Surgical treatment was superior to cinacalcet to correct the metabolic disorders of hyperparathyroidism despite being associated with worse renal function in the long term. Cinacalcet proved to be a safe and well tolerated drug.


RESUMO Introdução: O hiperparatireoidismo persistente pós-transplante está associado a aumento na incidência de eventos cardiovasculares, fraturas e óbitos. O objetivo deste estudo foi comparar as opções terapêuticas disponíveis: paratireoidectomia (PTX) e o agente calcimimético cinacalcete. Métodos: Estudo retrospectivo de um único centro incluiu pacientes transplantados renais adultos que desenvolveram hipercalcemia devido a hiperparatireoidismo persistente. Critérios de inclusão: PTH > 65 pg/mL com cálcio sérico > 11,5 mg/dL a qualquer momento após o transplante, ou cálcio sérico persistentemente superior a 10,2 mg/dL um ano após o transplante. Os pacientes tratados com cinacalcete (n = 46) foram comparados aos pacientes tratados com paratireoidectomia (n = 30). O período de acompanhamento foi de um ano. Dados clínicos e laboratoriais foram analisados para comparar a eficácia e a segurança de ambas as modalidades terapêuticas. Resultados: a PTX controlou a calcemia mais rapidamente (mês 1 x mês 6) e atingiu níveis significativamente mais baixos no mês 12 (9,1 ± 1,2 v.s. 9,7 ± 0,8 mg/dL, p < 0,05); pacientes submetidos à PTX apresentaram níveis significativamente mais altos de fósforo sérico (3,8 ± 1,0 v.s. 2,9 ± 0,5 mg/dL, p < 0,05) e retornaram aos níveis normais de PTH (45 ± 51 pg/mL). O cinacalcete, apesar de controlar o cálcio e o fósforo no longo prazo, diminuiu, mas não corrigiu o PTH (197 ± 97 pg/mL). A proporção de pacientes que permaneceram com PTH acima da faixa normal foi de 95% no grupo cinacalcete e 22% no grupo PTX. Os pacientes tratados com cinacalcete apresentaram melhor função renal (creatinina 1,2 ± 0,3 v.s. 1,7 ± 0,7 mg/dL, p < 0,05). Conclusões: O tratamento cirúrgico foi superior ao cinacalcete para corrigir os distúrbios metabólicos do hiperparatireoidismo, apesar de estar associado a pior função renal no longo prazo. Cinacalcete provou ser um medicamento seguro e bem tolerado.

ABSTRACT

Abstract Introduction: Renal fibrosis is the end point of a process that begins at transplant, with ischemia reperfusion and early inflammation, and progresses over time with immunological and non-immunological phenomena. Early identification of morphological markers and intervention could improve graft function and survival. Objective: to evaluate the correlation between intensity and specificity of pre-transplant anti-HLA antibodies and kidney allograft pathology in order to identify early risk factors or markers of allograft dysfunction. Methods: A retrospective cohort of kidney transplant recipients with pre-transplant anti-HLA antibodies who underwent graft biopsy within the first two years post-transplant was divided into two groups according to the specificity of anti-HLA antibodies: nonspecific (non-DSA, n = 29) and specific (DSA+, n = 16). Kidney graft pathology, renal function, and proteinuria were analyzed. Results: general characteristics were similar in both groups, except for the higher dose of thymoglobulin in DSA+ group (p < 0.05). The non-DSA group had higher scores for glomerulosclerosis, interstitial inflammation (i) and interstitial fibrosis (ci) (p < 0.05) and higher incidence of cell-mediated acute rejection. No statistical difference in incidence of antibody-mediated rejection, renal function, and proteinuria was observed during follow up. Discussion and conclusions: the difference in inflammation scores and interstitial fibrosis may be associated to the higher incidence of acute cell-mediated rejection and polyomavirus nephropathy in the Non-DSA group. We also should take into account the protective effect of higher doses of thymoglobulin, reducing ischemia reperfusion injury in the DSA+ group. The short follow-up might have been insufficient to detect long-term changes in allograft tissue, renal function, and proteinuria.


Resumo Introdução: A fibrose renal é o desfecho de um processo iniciado no transplante, com reperfusão, isquemia e inflamação precoce, que progride ao longo do tempo com fenômenos imunológicos e não imunológicos. A identificação de marcadores morfológicos e a intervenção precoce poderiam melhorar a função e a sobrevida do enxerto. Objetivo: Avaliar a correlação entre intensidade e especificidade de anticorpos anti-HLA pré-transplante alterações histológicas do enxerto renal, de forma a identificar fatores de risco ou marcadores de disfunção precoces do aloenxerto. Métodos: O presente estudo incluiu uma coorte retrospectiva de receptores de transplante renal sensibilizados com anticorpos anti-HLA no pré-transplante submetidos a biópsia de enxerto nos primeiros dois anos após o transplante. Os grupos foram divididos em função da especificidade dos anticorpos anti-HLA: sem anticorpos doador-específicos (não-DSA, n = 29) e com anticorpos doador-específicos (DSA+, n = 16). Alterações histológicas do enxerto renal, função renal e proteinúria foram analisados. Resultados: Os dois grupos tinham características gerais semelhantes, exceto pela dose mais elevada de timoglobulina administrada nos indivíduos do grupo DSA+ (p < 0,05). O grupo não-DSA teve escores mais elevados de glomeruloesclerose, inflamação intersticial (i) e fibrose intersticial (ci) (p < 0,05), além de maior incidência de rejeição celular aguda (RCA). Não foi observada diferença estatística na incidência de rejeição mediada por anticorpos, função renal ou proteinúria durante o seguimento. Discussão e Conclusões: A diferença nos escores de inflamação e fibrose intersticial pode estar associada à maior incidência de RCA e nefropatia por poliomavírus no grupo não-DSA. Devemos considerar ainda o efeito protetor das doses mais elevadas de timoglobulina na redução da lesão por isquemia-reperfusão no grupo DSA+. O curto período de seguimento pode ter sido insuficiente para detectar alterações de longo prazo no tecido do aloenxerto, função renal e proteinúria.

ABSTRACT

Abstract Early hospital readmission (EHR), defined as all readmissions within 30 days of initial hospital discharge, is a health care quality measure. It is influenced by the demographic characteristics of the population at risk, the multidisciplinary approach for hospital discharge, the access, coverage, and comprehensiveness of the health care system, and reimbursement policies. EHR is associated with higher morbidity, mortality, and increased health care costs. Monitoring EHR enables the identification of hospital and outpatient healthcare weaknesses and the implementation of corrective interventions. Among kidney transplant recipients in the USA, EHR ranges between 18 and 47%, and is associated with one-year increased mortality and graft loss. One study in Brazil showed an incidence of 19.8% of EHR. The main causes of readmission were infections and surgical and metabolic complications. Strategies to reduce early hospital readmission are therefore essential and should consider the local factors, including socio-economic conditions, epidemiology and endemic diseases, and mobility.


Resumo A Readmissão Hospitalar Precoce (RH), definida como todas as readmissões dentro de 30 dias após a alta hospitalar inicial, é uma métrica da qualidade hospitalar. É influenciada pelas características demográficas da população em risco, pela abordagem multidisciplinar da alta hospitalar inicial, pelo acesso, pela cobertura e pela abrangência do Sistema de Saúde e pelas políticas de reembolso. A readmissão hospitalar precoce está associada a maior morbidade, mortalidade e aumento dos custos com saúde. O monitoramento da RH permite a identificação das fragilidades hospitalares e ambulatoriais e a implementação de intervenções corretivas. Entre os receptores de transplante renal nos EUA, a RH varia entre 18% e 47% e está associada a maior mortalidade e perda do enxerto no primeiro ano do transplante. Um estudo no Brasil mostrou uma incidência de 19,8% de RH. As principais causas de readmissão foram infecções e complicações cirúrgicas e metabólicas. As estratégias para reduzir a readmissão hospitalar precoce são, portanto, essenciais e devem considerar o ambiente local, incluindo condições socioeconômicas, epidemiologia local, doenças e mobilidade endêmicas.

ABSTRACT

Abstract Introduction: Kidney Donor Profile Index (KDPI) has been incorporated in the United States to improve the kidney transplant allocation system. Objectives: To evaluate deceased kidney donors' profile using KDPI and compare to the previous United Network for Organ Sharing (UNOS) definition of expanded criteria donors (ECD) and assess the KDPI applicability to predict five-year graft survival and renal function in our sample. Methods: Retrospective cohort of 589 kidney transplants from deceased donors performed from January 2009 to May 2013 with follow-up until May 2018. Results: In 589 kidney transplants, 36.6% of donors were classified as ECD and 28.8% had KDPI ≥ 85%. Mean KDPI was 63.1 (95%CI: 60.8-65.3). There was an overlap of standard and ECD in KDPI between 60 and 95 and a significantly lower death-censored graft survival in KDPI ≥ 85% (78.6%); KDPI 0-20: 89.8%, KDPI 21-59: 91.6%, and KDPI 60-84: 83.0%; p = 0.006. The AUC-ROC was 0.577 (95%CI: 0.514-0.641; p = 0.027). Renal function at 5 years was significantly lower according to the incremental KDPI (p < 0.002). KDPI (HR 1.011; 95%CI 1.001-1.020; p = 0.008), donor-specific antibodies (HR 2.77; 95%CI 1.69-4.54; p < 0.001), acute rejection episode (HR 1.73; 95%CI 1.04-2.86; p = 0.034) were independent and significant risk factors for death-censored graft loss at 5 years. Conclusion: In our study, 36.6% were classified as ECD and 28.8% had KDPI ≥ 85%. KDPI score showed a moderate power to predict graft survival at 5 years. Renal function was significantly lower in patients with higher KDPI.


Resumo Introdução: O Índice de Perfil de Doadores de Rins (KDPI) foi adotado nos Estados Unidos para melhorar o sistema de alocação de transplantes renais. Objetivos: avaliar o perfil dos doadores de rim falecidos usando o KDPI e comparar com a definição anterior do United Network for Organ Sharing (UNOS) de doadores de critérios expandidos (DCE) e avaliar a aplicabilidade do KDPI para prever a sobrevida do enxerto em cinco anos e a função renal em nossa amostra. Métodos: Coorte retrospectiva de 589 transplantes renais de doadores falecidos, realizada de janeiro de 2009 a maio de 2013, com acompanhamento até maio de 2018. Resultados: Em 589 transplantes renais, 36,6% dos doadores foram classificados como DCE e 28,8% apresentaram KDPI ≥ 85%. O KDPI médio foi de 63,1 (IC 95%: 60,8-65,3). Houve uma sobreposição de padrão e DCE no KDPI entre 60 e 95 e uma sobrevida do enxerto censurada por óbito significativamente menor no KDPI ≥ 85% (78,6%); KDPI 0-20: 89,8%, KDPI 21-59: 91,6% e KDPI 60-84: 83,0%; p = 0,006. A ASC-ROC foi de 0,577 (IC 95%: 0,514-0,641; p = 0,027). A função renal aos 5 anos foi significativamente menor de acordo com o aumento do KDPI (p <0,002). KDPI (HR 1.011; 95% CI 1.001-1.020; p = 0.008), anticorpos específicos contra doadores (HR 2,77; 95% CI 1,69-4,54; p <0,001), episódio de rejeição aguda (HR 1,73; 95% CI 1,04-2,86; p = 0,034) foram fatores de risco independentes e significativos para perda do enxerto censurada por óbito em 5 anos. Conclusão: Em nosso estudo, 36,6% foram classificados como DCE e 28,8% apresentaram KDPI ≥ 85%. O escore KDPI mostrou potencial moderado para prever a sobrevida do enxerto em 5 anos.
