Palliative Care for End-Stage Renal Disease:A Case Report and Literature Review / 中国医学科学院学报

Since end-stage renal disease leads to a variety of problems such as disability,reduced quality of life,and mental and psychological disorders,it has become a serious public health problem around the globe.Renal palliative care integrates palliative care philosophy in the care for patients with end-stage renal disease.As a planned,comprehensive,patient-centered care,renal palliative care focuses on the patient's symptoms and needs,aiming to reduce the suffering throughout the course of the disease,including but not limited to end-of-life care.This study reports the palliative care practice for a patient on maintenance dialysis in the Blood Purification Center of Peking Union Medical College Hospital and reviews the present situation of palliative care in end-stage renal disease.

Analysis of etiology and complications in children with stage 5 chronic kidney disease / 中华儿科杂志

Objective: To investigate the etiology, complications, and prognostic factors of stage 5 chronic kidney disease (CKD5) in children. Methods: A case series study was conducted to retrospectively analyze the general situation, clinical manifestations, laboratory tests, genetic testing, and follow-up data (until October 2022) of 174 children with CKD5 who were diagnosed and hospitalized at the Children's Hospital of Chongqing Medical University from April 2012 to April 2021. The characteristics of complications in the children were compared based on age, gender, and etiology. Based on the presence or absence of left ventricular hypertrophy (LVH), patients were divided into LVH group and non LVH group for analyzing the influencing factors of cardiovascular disease. Patients were also divided into death group and survival group, peritoneal dialysis group and hemodialysis group based on the follow-up data for analyzing the prognostic factors. The chi-square test, independent sample t-test, Fisher exact probability test, Mann-Whitney U test and Kruskal Wallis test were used to analyze data among different groups. Multivariate Logistic regression analysis was used to identify the prognostic factors. Results: A total of 174 children with CKD5 were enrolled in the study (96 boys and 78 girls), aged 11.2 (8.2, 13.0) years. Congenital kidney and urinary tract malformations (CAKUT) were the most common causes of the CKD5 (84 cases, 48.3%), followed by glomerular diseases (83 cases, 47.7%), and among which 28 cases (16.1%) were hereditary glomerular diseases. The common complications of CKD5 included anemia (98.2%, 165/168), mineral and bone disorder in chronic kidney disease (CKD-MBD) (97.7%, 170/174), lipid metabolism disorders (87.5%, 63/72), hypertension (81.4%, 127/156) and LVH (57.6%,57/99). The incidences of hypertension in primary glomerular disease were higher than that in CAKUT(93.8%(30/32) vs.73.7%(56/76),χ2=5.59,P<0.05). The incidences of hypertension in secondary glomerular disease were higher than that in CAKUT and that in hereditary kidney disease (100.0%(20/20) vs. 73.7%(56/76), 68.2%(15/22), both P<0.05). The incidence of hypocalcemia in CAKUT, primary glomerular disease, and hereditary kidney disease was higher than that in secondary glomerular disease (82.1%(69/84), 88.2%(30/34), 89.3%(25/28) vs. 47.6%(10/21), χ2=10.21, 10.75, 10.80, all P=0.001); the incidence of secondary hyperparathyroidism in women was higher than that in men (80.0%(64/80) vs. 95.0%(57/60), χ2=6.58, P=0.010). The incidence of LVH in children aged 6-<12 was higher than that in children aged 12-18 (73.5%(25/34) vs. 43.1%(22/51), χ2=7.62, P=0.006). Among 113 follow-up children, the mortality rate was 39.8% (45/113). Compared to the survival group, the children in the death group had lower hemoglobin, higher blood pressure, lower albumin, lower alkaline phosphatase and higher left ventricular mass index ((67±19) vs. (75±20) g/L, 142 (126, 154) vs. 128(113, 145) mmHg(1 mmHg=0.133 kPa), (91±21) vs. (82±22) mmHg, 32 (26, 41) vs. 40 (31, 43) g/L, 151 (82, 214) vs. 215 (129, 37) U/L, 48 (38, 66) vs. 38(32, 50) g/m2.7,t=2.03, Z=2.89, t=2.70, Z=2.49, 2.79, 2.29,all P<0.05), but no independent risk factors were identified (all P>0.05). The peritoneal dialysis group had better alleviation for anemia, low calcium, and high phosphorus than the hemodialysis group ((87±22) vs. (72±16) g/L, (1.9±0.5) vs. (1.7±0.4) mmol/L, (2.2±0.7) vs. (2.8±0.9) mmol/L, t=2.92, 2.29, 2.82, all P<0.05), and the survival rate of the peritoneal dialysis group was significantly higher than that of the hemodialysis group (77.8% (28/36) vs. 48.4% (30/62), χ2=8.14, P=0.004). Conclusions: CAKUT is the most common etiology in children with CKD 5, and anemia is the most common complication. The incidence of complications in children with CKD 5 varies with age, gender and etiology. Anemia, hypertension, hypoalbuminemia, reduced alkaline phosphatase and elevated LVMI may be the prognostic factors in children with CKD5. Peritoneal dialysis may be more beneficial for improving the long-term survival rate.

Relationship between dialysis quality and brain compliance in patients with end-stage renal disease (ESRD): a cross-sectional study

ABSTRACT BACKGROUND: The high number of patients with end-stage kidney disease (ESRD) on hemodialysis makes it necessary to conduct studies aimed at improving their quality of life. OBJECTIVES: To evaluate brain compliance, using the Brain4care method for intracranial pressure (ICP) monitoring, among patients with ESRD before and at the end of the hemodialysis session, and to correlate ICP with the dialysis quality index (Kt/V). DESIGN AND SETTING: Cross-sectional study conducted at a renal replacement therapy center in Brazil. METHODS: Sixty volunteers who were undergoing hemodialysis three times a week were included in this study. Brain compliance was assessed before and after hemodialysis using the noninvasive Brain4care method and intracranial pressure wave morphology was analyzed. RESULTS: Among these 60 ESRD volunteers, 17 (28%) presented altered brain compliance before hemodialysis. After hemodialysis, 12 (20%) exhibited normalization of brain compliance. Moreover, 10 (83%) of the 12 patients whose post-dialysis brain compliance became normalized were seen to present good-quality dialysis, as confirmed by Kt/V > 1.2. CONCLUSIONS: It can be suggested that changes to cerebral compliance in individuals with ESRD occur frequently and that a good-quality hemodialysis session (Kt/V > 1.2) may be effective for normalizing the patient's cerebral compliance.

¿Cómo viven su enfermedad las personas en diálisis?: una mirada cualitativa a la experiencia del paciente / How do patients on dialysis experience their disease? A qualitative approach

BACKGROUND: End-stage chronic kidney disease is a severe public health problem due to the poor quality of life of patients on dialysis and the costs associated with renal replacement treatment. Aim: To understand the social representations of kidney disease of people on dialysis. MATERIAL AND METHODS: In a qualitative study under the post-positivist paradigm, eighteen patients in peritoneal or hemodialysis participated in an in-depth interview. The analysis was performed using content analysis. Results: Eight categories were identified: Friends, Health Care Team, Spirituality and Disease, Family, Health Support System, Physical Consequences, Psychosocial Consequences, Self-Care of Continuous Health-Disease. CONCLUSIONS: Health care of people on dialysis should take into consideration the experience of kidney disease from the perspective of the patient, including his beliefs and feelings and involving the family, community, and the state.

Biochemical and histopathological evaluations of chronic renal failure rats treated with pluripotent human stem cells

Abstract Regeneration of damaged kidney cells using stem cells is the current research approach in the treatment of chronic renal failure (CRF). In the present study, the histopathological and biochemical techniques were used to evaluate stem cells' (SCs) role in treatment of CRF. Sixty-four rats were divided into eight groups. Group I (GI): rats were injected with doxorubicin (15 mg/kg) to initiate CRF. GII-GVII: rats were injected with doxorubicin and treated with SCs (1x106 MSCs or/and 2x104 HSCs/rat) with/without growth factors extract (200 µL/rat) and/or immunosuppressor (cyclosporine A, 5 mg/kg/day). GVIII: rats treated with PBS (100 µL/kg/day). Levels of creatinine, urea and uric acid were increased in rats sera after injection with doxorubicin, while blood electrolyte levels of Na, K, P and Mg were decreased. Also, histopathological abnormalities such as hyalinized blood vessels, degenerated hyalinized glomerulus tubules and cell debris in the lumen and degeneration of renal tissues were observed in these rats. After treatment with SCs, all these parameters restore their normal values with regeneration of the damaged cells as demonstrated in histopathology of the treated groups. It can be concluded that, the use of SCs in treatment of kidney diseases is a promising approach and needs more efforts.

Review of Leachable Substances in Hemodialyzer / 中国医疗器械杂志

With the rapid development of my country's hemodialysis industry, the application of hemodialysis machines has become more and more extensive, but at the same time, the quality control technology of hemodialysis machines is not perfect. Especially for a wide range of leachable substances in dialyzers, there are few studies and detection methods. This study first briefly describes the development of hemodialyzers, and then expounds the common types of leachables, extraction methods, and chromatography and mass spectrometry conditions. It is summarized that the research plan of leachable substances is to determine the type first, then formulate the extraction plan, and then establish the detection method. Finally, we look forward to the research prospects of hemodialyzer leachables, and point out that with the deepening and extensive development of research, it can further promote the healthy development of the hemodialyzer industry.

Health economics of kidney replacement therapy in Singapore: Taking stock and looking ahead

The prevalence of end-stage kidney disease (ESKD) in Singapore remains high and continues to rise. We continue to face major challenges in containing the rising incidence of ESKD and providing sustainable kidney replacement therapy. Our cost projections provide an insight into the present and future, urging a call to action to augment existing initiatives to address the emergent issues.

Comparison of planned-start, early-start and deferred-start strategies for peritoneal dialysis initiation in end-stage kidney disease

INTRODUCTION@#In patients with end-stage kidney disease (ESKD) suitable for peritoneal dialysis (PD), PD should ideally be planned and initiated electively (planned-start PD). If patients present late, some centres initiate PD immediately with an urgent-start PD strategy. However, as urgent-start PD is resource intensive, we evaluated another strategy where patients first undergo emergent haemodialysis (HD), followed by early PD catheter insertion, and switch to PD 48-72 hours after PD catheter insertion (early-start PD). Conventionally, late-presenting patients are often started on HD, followed by deferred PD catheter insertion before switching to PD≥14 days after catheter insertion (deferred start PD).@*METHODS@#This is a retrospective study of new ESKD patients, comparing the planned-start, early-start and deferred-start PD strategies. Outcomes within 1 year of dialysis initiation were studied.@*RESULTS@#Of 148 patients, 57 (38.5%) patients had planned-start, 23 (15.5%) early-start and 68 (45.9%) deferred-start PD. Baseline biochemical parameters were similar except for a lower serum urea with planned-start PD. No significant differences were seen in the primary outcomes of technique and patient survival across all 3 subgroups. Compared to planned-start PD, early-start PD had a shorter time to catheter migration (hazard ratio [HR] 14.13, 95% confidence interval [CI] 1.65-121.04, P=0.016) while deferred-start PD has a shorter time to first peritonitis (HR 2.49, 95% CI 1.03-6.01, P=0.043) and first hospital admission (HR 2.03, 95% CI 1.35-3.07, P=0.001).@*CONCLUSION@#Planned-start PD is the best PD initiation strategy. However, if this is not possible, early-start PD is a viable alternative. Catheter migration may be more frequent with early-start PD but does not appear to impact technique survival.

Death and cardiovascular outcomes in end-stage renal failure patients on different modalities of dialysis

INTRODUCTION@#Cardiovascular morbidity and mortality in end-stage renal failure (ESRF) patients are high. We examined the incidence and predictors of death and acute myocardial infarction (AMI) in ESRF patients on different modalities of dialysis.@*METHOD@#Data were obtained from a population-based database (National Registry Disease Offices) in Singapore. The study cohort comprised all adult patients initiated on dialysis between 2007 and 2012 who were closely followed for the development of death and AMI until September 2014. Cox regression methods were used to identify predictors of death and AMI.@*RESULTS@#Of 5,309 patients, 4,449 were on haemodialysis and 860 on peritoneal dialysis (PD). Mean age of the cohort was 61 (±13) years (44% women), of Chinese (67%), Malay (25%) and Indian (7%) ethnicities. By September 2014, the incidence of all-cause death was 34%; close to a third of the patients died from a cardiovascular cause. Age >60 years and the presence of ischaemic heart disease, diabetes, stroke, peripheral vascular disease and PD were identified as independent predictors of all-cause death. PD patients had lower odds of survival compared to patients on haemodialysis (hazard ratio 1.51, 95% confidence interval 1.35-1.70, P<0.0001). Predictors of AMI in this cohort were older age (>60 years) and the presence of ischaemic heart disease, diabetes, stroke, peripheral vascular disease and current/ex-smokers. There were no significant differences in the incidence of AMI between patients on PD and haemodialysis.@*CONCLUSION@#The short-term incidence of death and AMI remains high in Singapore. Future studies should investigate the benefits of a tighter control of cardiovascular risk factors among ESRF patients on dialysis.

Quality of life in primary caregivers of patients in peritoneal dialysis and hemodialysis / Qualidade de vida em cuidadores primários de pacientes em diálise peritoneal e hemodiálise

Abstract Background: Peritoneal dialysis (PD) is gaining track as an efficient/affordable therapy in poor settings. Yet, there is little data regarding differences in quality of life (QoL) of primary caregivers (PCG) of patients in PD and hemodialysis (HD). Aim: To compare the QoL of PCG of patients in PD and HD from an upper middle-income population in a Mexican city. Methods: Cross-sectional study was carried out with PCG of patients in PD (n=42) and HD (n=95) from 4 hospitals (response rate=70.2%). The SF 36-item QoL questionnaire, the Zarit burden interview, and the Goldberg anxiety/depression scale were used. Mean normalized scores for each QoL domain were compared by dialysis type. Adjusted odds were computed using logistic regression to determine the probability of low QoL (<70% of maximum possible score resulting from the added scores of the 8 dimensions). Results: The PD group had higher mean scores for emotional role functioning (+10.6; p=0.04), physical functioning (+9.2; p=0.002), bodily pain (+9.2; p=0.07), social functioning (+5.7; p=0.25), and mental health (+1.3; p=0.71); the HD group had higher scores for physical role functioning (+7.9, p=0.14), general health perception (+6.1; p=0.05), and vitality (+3.3; p=0.36). A non-significant OR was seen in multivariate regression (1.51; 95% CI 0.43-5.31). Zarit scores were similar, but workload levels were lower in the PD group (medium/high: PD 7.2%, HD 14.8%). Anxiety (HD 50.5%, PD 19%; p<0.01) and depression (HD 49.5%, PD 16.7%; p<0.01) were also lower in the PD group. Conclusion: Adjusted analysis showed no differences in the probability of low QoL between the groups. These findings add to the value of PD, and strengthen its importance in resource-limited settings.

Resumo Histórico: A diálise peritoneal (DP) vem ganhando terreno como terapia eficiente/acessível em ambientes pobres. Contudo, há poucos dados sobre diferenças na qualidade de vida (QV) dos cuidadores primários (CP) de pacientes em DP e hemodiálise (HD). Objetivo: Comparar QV dos CP de pacientes em DP e HD de uma cidade mexicana de renda média. Métodos: Estudo transversal com CP de pacientes em DP (n=42) e HD (n=95) de 4 hospitais (taxa resposta=70,2%). Aplicou-se o questionário QV-36 itens, entrevista de sobrecarga de Zarit e escala de ansiedade/depressão Goldberg. Escores médios normalizados para cada domínio de QV foram comparados por tipo de diálise. Probabilidades ajustadas foram calculadas usando regressão logística para determinar a probabilidade de baixa QV (<70% da pontuação máxima possível resultante das pontuações adicionadas das 8 dimensões). Resultados: O grupo DP apresentou escores médios mais altos para aspectos emocionais (+10,6; p=0,04), capacidade funcional (+9,2; p=0,002), dor (+9,2; p=0,07), aspectos sociais (+5,7; p=0,25), saúde mental (+1,3; p=0,71); o grupo HD teve pontuação maior para aspectos físicos (+7,9, p=0,14), estado geral de saúde (+6,1; p=0,05), vitalidade (+3,3; p=0,36). Uma probabilidade não significativa foi observada na regressão multivariada (OR=0,66; 95% IC 0,18-2,31). Os escores de Zarit foram semelhantes, mas os níveis da sobrecarga foram menores na DP (médio/alto: DP 7,2%, HD 14,8%). Ansiedade (50,5% vs 19%; p<0,01) e depressão (49,5% vs 16,7%; p<0,01) foram menores na DP. Conclusão: O risco de baixa QV entre grupos não foi diferente na análise ajustada. Estes achados fortalecem a importância da DP em ambientes com recursos limitados.

Evaluación de la calidad de vida de pacientes chilenos en diálisis peritoneal mediante el cuestionario KDQOL-36 / Health-related quality of life of patients on peritoneal dialysis

BACKGROUND: Health-related quality of life (HRQoL) is an important predictor of health outcomes in chronic kidney disease (CKD) including those patients in renal replacement therapy. Its evaluation through validated questionnaires is essential for comprehensive care in people undergoing renal replacement therapy. AIM: To evaluate the quality of life in patients with CKD on peritoneal dialysis. MATERIAL AND METHODS: Descriptive cross-sectional study. The KDQOL-36 quality of life questionnaire was applied to 67 patients aged 55 ± 15 years, in peritoneal dialysis at a public hospital in Santiago. Scores range from 0 to 100, values greater than 50 represent a better HRQoL. RESULTS: The burden, symptoms, and effects of kidney disease component of the survey had scores over 50. Women, people without diabetes, those actively working and those with better incomes reported a better HRQoL. CONCLUSIONS: These patients on peritoneal dialysis report a good quality of life, especially in the specific components of kidney disease.

Rehabilitación del intestino utilizando un análogo semisintético del péptido 2 similar al glucagón. Primera experiencia con teduglutide en Uruguay / Intestinal rehabilitation using semisynthetic glucagon-like peptide-2 analogue. First experience with teduglutide in Uruguay / Reabilitação do intestino usando um análogo semi-sintético do peptídeo 2 semelhante ao glucagon. Primeira experiência com teduglutide no Uruguai

Resumen: La falla intestinal crónica (FIC) o tipo III es una condición invalidante, y la nutrición parenteral crónica (NPC) domiciliaria es el tratamiento que permite a estos pacientes mantenerse con vida. Sin embargo, solamente uno de cada tres países latinoamericanos cuentan con ese recurso, y sus complicaciones no son infrecuentes. Estas complicaciones son las principales indicaciones para trasplante intestinal, un procedimiento que en la mayoría de los países de ingresos medios no se ha desarrollado y no ha presentado los resultados esperados. En los últimos años, la rehabilitación intestinal a nivel mundial ha mejorado sustancialmente con el uso de análogos semisintéticos del péptido 2 similares al glucagón, existiendo cada vez mayor evidencia que demuestra la posibilidad de rehabilitación intestinal e independencia de la NPC con este fármaco, incluso en pacientes con anatomía desfavorable. Estos resultados han permitido mejorar la supervivencia y la calidad de vida de pacientes con FIC y, en muchas ocasiones, prescindir del trasplante. El paciente del caso que presentamos es el primero en recibir esta terapéutica en nuestro país. En este artículo analizamos la respuesta precoz favorable al tratamiento y sus perspectivas a futuro.

Abstract: Long-term home parenteral nutrition (HPN) is a life-saving treatment for patients with chronic intestinal failure, an invalidating condition. However, only 1 out of 3 countries can rely on this treatment and complications associated to chronic parenteral nutrition are rather frequent. The latter constitute the main indication for intestinal transplantion, a procedure that in most middle-income countries has not yet developed and has not shown the expected outcome. In recent years, intestinal rehabilitation has significantly improved at the global level with the use of GLP2, based on the growing evidence that proves the possibility of intestinal rehabilitation and independence from parenteral nutrition with Teduglutide, even in the case of patients with unfavorable anatomy. These results have caused a positive impact on survival and the quality of life of patients with chronic renal failure, and they can often abstain from transplant. The patient of the case study is the first one who received this therapy in our country and this article analyses his favorable early response to treatment and future perspectives.

Resumo: A insuficiência intestinal crônica (CIF) ou tipo III é uma condição incapacitante e a nutrição parenteral crônica (NPC) domiciliar é o tratamento que permite a sobrevida desses pacientes. No entanto, apenas 1 em cada 3 países latino-americanos dispõe desse recurso e as complicações da NPC não são raras. Essas complicações são as principais indicações para o transplante intestinal, procedimento que na maioria dos países de renda média não foi desenvolvido ou não apresentou os resultados esperados. Nos últimos anos, a reabilitação intestinal em todo o mundo tem melhorado substancialmente com o uso de sGLP2, com um número cada vez maior de evidências que mostram a possibilidade de reabilitação intestinal e independência da NPC, mesmo em pacientes com anatomia desfavorável. Esses resultados têm possibilitado prolongar a sobrevida e melhorar a qualidade de vida dos pacientes com CIF e, em muitos casos, dispensar o transplante. O paciente do caso que apresentamos é o primeiro a receber essa terapia em nosso país. Neste artigo, analisamos a resposta favorável ao tratamento precoce e suas perspectivas futuras.

Urgent vs. early-start peritoneal dialysis: patients' profile and outcomes / Diálise peritoneal de urgência vs. início precoce: perfil dos pacientes e resultados

ABSTRACT Introduction: Peritoneal dialysis (PD) has been considered a safe option of therapy in end-stage renal disease patients with urgent need of dialysis. Recently, it was proposed that Urgent-Start-PD (US-PD) be defined when PD starts within 72 hours after catheter placement and "early start" PD (ES-PD) when PD starts between 3 and 14 days after. We aimed to compare demographic and clinical characteristics between patients in US-PD and ES-PD as well as 30-day complications, 6-month hospitalization, and dropout rate. Methods: Adult patients starting PD within 14 days after catheter insertion (October/2016 - February/2019) were included and divided into US-PD group and ES-PD group based on the their PD initiation time. Clinical and demographic data, fill volume for the first PD session, 30-day complications, 6-month hospitalization, and dropout rate were assessed. Results: In our study, 72 patients were analyzed (US-PD=40, ES-PD=32) with mean age of 53.2±15.2 years old. No differences between US-PD and ES-PD regarding demographic characteristics, 30-day complications, 6-month hospitalization, and dropout events were found. The most frequent short-term complication in patients who started PD urgently was leakage. The most common cause of dropout was transfer to HD. Conclusion: Fifty five percent of our sample started PD less than 72 hours after catheter insertion. The lack of difference in the measured outcomes compared to patients that had therapy initiated after this period encourages the use of urgent PD when needed.

RESUMO Introdução: A diálise peritoneal (DP) tem sido considerada uma opção segura de terapia em pacientes com doença renal terminal com necessidade urgente de diálise. Recentemente, foi proposto que a DP de início urgente (US-PD) fosse definida quando a DP iniciar dentro de 72 horas após o implante do cateter, e a DP de "início precoce" (ES-PD) quando a DP iniciar entre 3 e 14 dias após o procedimento. Nosso objetivo foi comparar características demográficas e clínicas entre pacientes em US-PD e ES-PD, bem como complicações em 30 dias, internação por 6 meses e taxa de saída do tratamento. Métodos: Pacientes adultos iniciando DP em até 14 dias após a inserção do cateter (outubro/2016 - fevereiro/2019) foram incluídos e divididos no grupo US-PD ou ES-PD com base no tempo de início da DP. Dados clínicos e demográficos, volume de preenchimento na primeira sessão de DP, complicações em 30 dias, hospitalização por 6 meses e taxa de saída foram avaliados. Resultados: Em nosso estudo, 72 pacientes foram analisados (US-PD = 40, ES-PD = 32) com média de idade de 53,2 ± 15,2 anos. Não foram encontradas diferenças entre US-PD e ES-PD em relação às características demográficas, complicações em 30 dias, hospitalização por 6 meses e saída do tratamento. A complicação de curto prazo mais frequente nos pacientes que iniciaram a DP com urgência foi o extravasamento de líquido peritoneal. A causa mais comum de saída foi a transferência para HD. Conclusão: Mais da metade da nossa amostra iniciou a DP menos de 72 horas após a inserção do cateter. A falta de diferença nos desfechos mensurados em comparação com os pacientes que iniciaram o tratamento após esse período incentiva o uso de US-PD quando necessário.

The spleen size in patients undergoing hemodialysis / O tamanho do baço em pacientes em hemodiálise

Abstract Introduction: Inflammation promotes the progression of chronic renal failure, and the start of dialysis worsens inflammation. The enlargement of the spleen is associated with inflammation, and patients on hemodialysis may show a large spleen. The aim of the present study was to compare the spleen size of patients undergoing hemodialysis versus controls to update this thread. Methods: Controls and patients were eligible to participate in the study provided they were negative for serological markers of hepatitis B and C viruses and HIV, if they had no lymphoproliferative disorder, and if they were at least 18 years of age. Age, sex, and the duration of dialysis were recorded. Laboratory variables (hemoglobin, hematological cell count, serum creatinine) and the underlying cause of end-stage renal disease were analyzed. The spleen sizes of the patients were divided into tertiles. Results: The 75 controls and 168 patients selected were sex-matched. The patients were older, had larger spleens and lower platelet counts than controls. The relationship between spleen size and age in the controls and patients was quite similar. The patients in the first tertile of spleen size compared with those in the third were older and had a higher platelet counts. The underlying disease and dialysis vintage had no effect on spleen size. Discussion: The patients had larger spleens and a greater range of spleen sizes than the controls. In patients, the association between larger and smaller spleen with lower and higher platelet counts, respectively, sparked the speculation of occurrence of hypersplenism and hyposplenism.

Resumo Introdução: A inflamação promove a progressão da insuficiência renal crônica, e o início da diálise agrava a inflamação. O aumento do baço está associado à inflamação e os pacientes em hemodiálise podem apresentar um baço grande. O objetivo do presente estudo foi comparar o tamanho do baço de pacientes em hemodiálise versus aquele de controles, para atualizar este tópico. Métodos: Controles e pacientes foram elegíveis para participar do estudo desde que fossem negativos para marcadores sorológicos dos vírus da hepatite B, C e HIV, se não apresentassem distúrbio linfoproliferativo e tivessem pelo menos 18 anos de idade. Registramos idade, sexo e duração da diálise. Avaliamos as variáveis laboratoriais (hemoglobina, contagem de células hematológicas, creatinina sérica) e a causa básica da doença renal terminal. O tamanho dos baços dos pacientes foram divididos em tercis. Resultados: Os 75 controles e 168 pacientes selecionados foram pareados por sexo. Os pacientes eram mais velhos, tinham baços maiores e menor contagem de plaquetas do que os controles. A relação entre o tamanho do baço e a idade dos controles e pacientes foi bastante semelhante. Os pacientes do primeiro tercil de tamanho do baço, em comparação com os do terceiro, eram mais velhos e apresentavam contagens de plaquetas mais altas. A doença subjacente e o período de diálise não tiveram efeito no tamanho do baço. Discussão: Os pacientes tinham baços maiores e uma maior variedade de tamanhos de baço do que os controles. Entre os pacientes, a associação entre baço maior e menor com contagens de plaquetas mais baixas e mais altas, respectivamente, gerou a especulação da ocorrência de hiperesplenismo e hiposplenismo.

Treatment of tegumentary leishmaniasis in two hemodialysis patients with end-stage renal disease using two series of pentamidine

Abstract In this study, we present two cases of cutaneous leishmaniasis in patients with end-stage renal disease, who were treated solely with intramuscular pentamidine. In such cases, treatment implies a fine line between therapeutic efficacy and toxicity. This is suggestive of a knowledge gap; however, findings indicate that this is still the fastest and safest alternative to the treatment with antimonials. Also, it can help avoid the side effects that occur upon using antimonials.

Demographics and clinical features of elderly patients undergoing regular dialysis in Brazil

An increasing number of elderly people in renal support is expected in the coming years. The objective of this study was to report the clinical and socio-demographic data of end-stage renal disease (ESRD) adult patients undergoing regular dialysis treatment comparing elderly (≥65 years old) and non-elderly subjects using data from the Brazilian Dialysis Registry database. The regional distribution of the sample was Southeast (48.8%), South (33.7), Northeast (13.1%), Midwest (5.1%), and North (0.1%). A total of 18,030 patients were included in the analysis with elderly patients accounting for 29.5% of the sample. The elderly patients were predominantly male, white, retired, and literate. Elderly ESRD patients had a slightly higher frequency of undernourishment and a lower frequency of obesity than the non-elderly adults. A higher frequency of elderly patients were from the South and Southeast regions. The dialysis treatment of patients from both groups was predominantly funded by the public system, but the percent of non-public funding was higher for the elderly group. The most used initial access in the elderly was the central venous catheter and hemodialysis was the main modality at the beginning of treatment (93.2%), as well as during maintenance therapy (91.8%). Advanced age was associated with greater use of central venous catheter in the first dialysis session. The survival of the elderly on dialysis was lower than that of the non-elderly early in the course of dialysis and this difference increased over time. This is yet the largest national epidemiological study of elderly people on chronic dialysis.

Opinions about Death in People Receiving Dialysis

ABSTRACT Objective: People receiving dialysis have a high mortality rate due to life-threatening, chronic renal failure. These patients experience the fear of pain and suffering, loneliness and death in the haemodialysis unit. This research aimed at determining the perception of death in people receiving dialysis. Methods: A cross-sectional, descriptive research was conducted under the supervision of the Ministry of Health in public hospitals in the cities of Mersin, Izmir, Antalya, Erzurum, Samsun and Gaziantep. A total 240 patients were treated in the dialysis units of these hospitals. Participants were selected with stratified random sampling. For data collection, a patient information form was prepared by the researcher. Data from the study were analysed with Tukey Honest Significant Difference and one-way ANOVA, using an SPSS version 11.5 software package (Statistical Package for the Social Sciences Windows, IBM Corp., Armonk, NY). The statistical significance level was defined as p < 0.05. Results: People receiving dialysis were found to be in a mildly depressive emotional state and they had death anxiety. Death-related anxiety and depression were more common among the female study participants compared to the male participants. Single patients exhibited higher levels of death anxiety compared to married patients. Conclusion: We recommend a holistic and personalised care to allow people receiving dialysis to express their feelings and to overcome the death anxiety. Further research is needed to improve dignified person-centred care for people receiving dialysis.

Safety and effectiveness of left atrial appendage occlusion in patients with atrial fibrillation and end-stage renal disease undergoing long-term hemodialysis / 中华心血管病杂志

Objective: To evaluate the safety and effectiveness of left atrial appendage occlusion (LAAO) in patients with atrial fibrillation and end-stage renal disease undergoing long-term hemodialysis. Methods: Six patients with AF and end-stage renal disease(ESRD)on long term hemodialysis who underwent LAAO from March 2017 to March 2021 in Beijing Anzhen Hospital were enrolled. Baseline characteristics such as age, sex, types of arrhythmia, stroke and bleeding score, and continuous dialysis time were collected. Four patients underwent LAAO, two patients underwent the combined procedure of catheter ablation and LAAO. Perioperative treatment and serious complications were recorded. Transesophageal echocardiography was repeated at 45 days and 60 days after the procedure. Telephone follow-up was conducted at 3, 6 and 12 months after the procedure, and every 6 months thereafter. Thromboembolism and major bleeding events and survival were evaluated. Results: The average age was (66.7±17.0) years old, and 5 were male (5/6). There were 4 patients with paroxysmal AF (4/6), and 2 patients with persistent AF (2/6). The mean CHA2DS2-VASc score was (4.8±1.5), and the HAS-BLED score was (3.5±1.4). The duration of hemodialysis was 2.6 (1.1, 8.3) years. Successfully Watchman implantation was achieved in all patients. There were no severe perioperative complications, and no device related thrombosis or leaks were observed by transesophageal echocardiography. During a mean of 22.0 (12.0, 32.0) months follow-up, there was no thromboembolism or major bleeding events. A total of 2 patients died, one from sudden cardiac death, and another one from heart failure. Conclusions: LAAO may be a safe and effective therapeutic option for prevention of thromboembolism in patients with atrial fibrillation and end-stage renal disease undergoing long-term hemodialysis, further studies with larger patient cohort are needed to confirm our results.
