RESUMO
Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect multiple organs and body systems. Objective: To describe the sociodemographic, clinical, and biochemical characteristics of the Lupus-IMMS-Mexico (LUPUS-IMMex) patient cohort from a tertiary-level center. Material and methods: Observational descriptive study of 160 patients with diagnosis of SLE belonging to the aforementioned cohort. Various variables were analyzed at the time of diagnosis. For quantitative variables, normality tests were applied, followed by measures of central tendency and dispersion according to their distribution. For categorical variables, frequencies and percentages were calculated. Results: 81.87% of the patients were female, with a median age at diagnosis of 28 years. 18.12% had a family history of SLE, and concurrently with SLE, 32.50% had hypertension, and 11.25% had antiphospholipid syndrome. The most common clinical manifestation was joint involvement (68.12%), renal (49.37%) and hematological (43.75%) manifestations. Conclusions: SLE affects millions globally. Lack of awareness leads to delayed diagnoses, suboptimal management, and diminished quality of life. After analyzing 160 patients with SLE, their clinical, socioeconomic, and therapeutic characteristics are largely like other cohorts, with differences attributable to ethnic and geographical influences. Informing patients about SLE and providing reliable resources are essential for self-care. Awareness promotes research, therapies, and enhances medical care and the lives of patients globally.
Introducción: el lupus eritematoso sistémico (LES) es una enfermedad autoinmunitaria crónica que puede afectar a múltiples órganos y sistemas del cuerpo. Objetivo: describir las características sociodemográficas, clínicas y bioquímicas de la cohorte de pacientes Lupus-IMMS-México (LUPUS-IMMex) de un hospital de tercer nivel. Material y métodos: estudio descriptivo observacional de 160 pacientes con diagnóstico de LES de la cohorte mencionada. Se analizaron diversas variables al momento del diagnóstico. Para variables cuantitativas se aplicaron pruebas de normalidad y posteriormente medidas de tendencia central y dispersión de acuerdo con su distribución. Para variables categóricas se calcularon frecuencias y porcentajes. Resultados: 81.87% de los pacientes fueron del sexo femenino, con mediana de edad al diagnóstico de 28 años. El 18.12% tenían antecedentes familiares de LES y concomitante al LES, hipertensión (32.50%) y síndromes antifosfolípidos (11.25%). Las afecciones clínicas más frecuentes fueron la articular (68.12%), la renal (49.37%) y la hematológica (43.75%). Conclusiones: el LES afecta a millones de personas globalmente. La falta de conciencia lleva a diagnósticos tardíos, manejo deficiente y baja calidad de vida. Tras analizar 160 pacientes con LES, sus características clínicas, socioeconómicas y terapéuticas son mayormente similares a otras cohortes, con diferencias atribuibles a influencias étnicas y geográficas. Informar a los pacientes sobre el LES y brindar recursos confiables es esencial para el autocuidado. La sensibilización fomenta la investigación, las terapias y mejora la atención médica y la vida de pacientes a nivel global.

Introducción: el embarazo causa adaptaciones en el riñón, tanto en anatomía como en función, para mantener el entorno extracelular, hemodinámico y hormonal. Sin embargo, estos pueden no llevarse a cabo de manera completamente óptima en presencia de enfermedad renal. El objetivo era estudiar la relación entre la enfermedad renal y los resultados maternos de fetal durante el embarazo, asociado con un rechazo por paciente y/o en relación con el tratamiento especializado. Material y métodos: estudio observacional y retrospectivo en una serie de casos, revisando 134 archivos de pacientes embarazadas con cierto grado de enfermedad renal antes del embarazo. Los resultados maternos registrados fueron: enfermedad hipertensiva durante el embarazo, deterioro renal agudo, necesidad de terapia de sustitución renal y en productos: prematuridad, restricción del crecimiento intrauterino, muerte fetal y aborto espontáneo. Resultados: Resultados maternos: tasa media de filtración glomerular (GFR) de 58.23 ml/min, aumento de peso de 7 kg; La preeclampsia fue diagnosticada en 92 mujeres (55 severas). 46 pacientes mostraron lesión renal aguda, 40 se resolvieron conservativamente; 1 requirió diálisis peritoneal y 15 hemodiálisis (con una decisión retrasada un promedio de un mes por rechazo por paciente y/o pariente). La resolución del embarazo fue por cesárea en 111 pacientes; Nacieron 116 productos antes de las 37 semanas de gestación, con un peso promedio de 1910 g, 94 mostraron restricción del crecimiento intrauterino. Conclusión: la enfermedad renal influyó directamente en el mayor número de resultados adversos maternos y fetales cuando se rechazó la atención médica especializada. Existe una correlación entre el ligero estado de Davison con los estados I, II y IIIA de Kdigo en el análisis de correspondencia
Introduction: Pregnancy causes adaptations in the kidney, both in anatomy and function, to maintain the extracellular, hemodynamic and hormonal environment. However, these may not be carried out completely optimally in the presence of kidney disease. The objective was to study the relation between kidney disease and maternal-fetal outcomes during pregnancy, associated with a rejection by patient and/or relative to specialized treatment. Material and Methods: Observational, retrospective study in a series of cases, reviewing 134 files of pregnant patients with some degree of kidney disease prior to pregnancy. Maternal outcomes recorded were: hypertensive disease during pregnancy, acute renal deterioration, need for renal substitution therapy, and in products: prematurity, restriction of intrauterine growth, fetal death and miscarriage. Results: Maternal outcomes: mean glomerular filtration rate (GFR) of 58.23ml/min, weight gain of 7 kg; preeclampsia was diagnosed in 92 women (55 severe). 46 patients showed acute renal lesion, 40 were conservatively resolved; 1 required peritoneal dialysis and 15 hemodialysis (with decision delayed an average of one month by rejection by patient and/or relative). Resolution of pregnancy was by cesarean in 111 patients; 116 products were born before 37 weeks of gestation, with average weight of 1910 g, 94 showed restriction of intrauterine growth. Conclusion: Kidney disease directly influenced the greater number of adverse maternal and fetal outcomes when specialized medical care was rejected. There is a correlation between slight Davison state with states I, II and IIIa of KDIGO in correspondence analysis.

OBJECTIVE: To analyze the evolution of the stages of CKD and the progression of the estimation of glomerular filtration rate (eGFR) in patients with newly diagnosed hypertension. DESIGN: Retrospective cohort. SITE: Family Medicine Unit No. 31, Mexican Social Security Institute, Mexico City. PARTICIPANTS: Patients with hypertension who have been diagnosed in primary care and have developed chronic kidney disease. MAIN MEASUREMENTS: The eGFR was calculated with the CKD Epi formula in three moments, the first measurement was at the time of diagnosis of hypertension, the second measurement was made when it arrived a change in CKD stage and the last one at the end of the study, with which the evolution time from one stage to another was obtained, as well as the drop in eGFR. RESULTS: The sample consisted of 207 electronic health records of patients, with an average follow-up of 10.2 years from the moment of diagnosis of hypertension until the end of the study. The average time to go from one baseline stage of CKD to another was 7 years (average decline in eGFR of 5.8ml/min/year) and to have a second stage change was 3.2 years (average decline in eGFR of 6.8ml/min/year), with a statistically significant repeated measures ANOVA (p<0.001). CONCLUSIONS: Patients with newly diagnosed hypertension remain longer in the initial stages of CKD, to later evolve and change more quickly.

Background: Knowledge of the functionality of the graft and patient survival is essential to assess the success of kidney transplantation. Objective: To determine the survival of transplanted patients by type of donor and the functionality of kidney grafts in a cohort in Mexico. Material and methods: Kidney transplant cohort from 2013 to 2017 in Mexico. 790 patients followed up for one year were analyzed to assess the survival of transplanted patients by type of donor and the functionality of kidney grafts. For this, measures of central tendency and dispersion were used, as well as Kaplan-Meier survival tables with SPSS, version 25. Results: Out of the 790 patients, 518 were from living donors (65.56%) with patient survival of 97.88% and graft function of 93.24% at 12 months of follow-up; 272 patients received the graft from a deceased donor with patient survival of 91.18% and renal graft function of 84.19%. Conclusions: There is still a difference of almost 5% in the survival of the recipient patient from a living donor compared to a deceased donor. For the functionality of the kidney graft, this difference is > 7%. Cadaveric donation has increased; however, even at low figures is of approximately 35% in Mexico.

INTRODUCTION: For the majority of renal replacement therapy history, the main treatment option for patients with end-stage renal disease (ESRD) in Mexico has been peritoneal dialysis. However, the use of hemodialysis is overwhelmingly increasing, driving public health care institutions to subrogate this service. Even when the actual hiring model for subrogation is accurate, there is a lack of quality control points in the hemodialysis prescription, poor adherence to clinical practice guidelines, and a few or no record of outcomes in hemodialysis patients of these subrogated services. The objective of this work is to fill this information gap to allow for uniform and safe hemodialysis for patients of Mexico. MATERIAL AND METHODS: An observational and cross-sectional study was performed, including all patients receiving chronic hemodialysis treatment in subrogated units of Mexican Social Security Institute (IMSS) in the northern region of Mexico City. Clinical and biochemical data as well as hemodialysis dose by Kt/V and urea reduction rate were collected and evaluated. To determine distribution, mean or median and SD or interquartile range were used; for nominal variables, the difference in proportions was estimated using the χ2 test; proportions were analyzed for biochemical values using the statistical package SPSS version 25. RESULTS: In our study, >60% (485) of the patients were anemic with an average hemoglobin of 9.39 mg/dL (SD ± 1.83); serum calcium was found below 8.4 mg/dL in 51.3% (383) of patients, and only in 45.8% (342) was at an optimal level of this parameter. Only 33.5% of patients have arteriovenous fistula for dialysis access. The hemodialysis dose was optimal in >75% of patients. CONCLUSIONS: It is necessary to enhance and monitor treatment of comorbidities in patients with ESRD in subrogated hemodialysis units in México. We observed adequate prescription of hemodialysis in a majority of patients, achieving quality control points for removal of nitrogen products. Yet, there is a lack of quality control of comorbidities; therefore, we should aim to optimize treatment for mineral-bone disorder, anemia, and nutritional status.

BACKGROUND/AIMS: Vascular access (VA) is the highest risk factor for blood infections, hospitalization, and mortality of patients undergoing hemodialysis (HD). The risk of mortality while using a catheter is greater than that while using grafts. The objective of this article is to know the survival rate in relation to the type of VA. METHODS: A retrospective cohort of HD patients was studied. The data gathered included age, gender, first VA at the surrogate site, days between the first and second access, number of accesses, and anatomical site of VA placement. Mean differences were estimated using χ2 or Student's t test. Survival was calculated using the Kaplan-Meier curves and included in tables. Statistical significance was established as p < 0.05. The statistical computer software package SPSSw v25 was used for the analysis. RESULTS: A total of 896 patients were included with a mean age of 47.88 years (SD ± 16.52), the duration of the first VA was 398.81 days (±565.79), the mean number of VAs used was 2.26 (±1.15), and the median time undergoing HD was 728.73 days. The duration of catheter placement was 330.42 days, and 728.60 days for fistula use (p = 0.001). The mean number of days of renal replacement was 611.59 days for catheter and 1,495.25 days for internal arteriovenous fistula (IAVF) patients (p = 0.001). CONCLUSIONS: The survival of the initial VA is greater for the IAVF, followed by the tunneled catheters and the lowest by the non-tunneled catheters, which continue to be frequently used in our setting.

INTRODUCTION: Renal transplantation presents multiple complications after its completion, some of them related to the behavior of hemoglobin levels. The objective of this study is to determine the behavior and prevalence of anemia and erythrocytosis in the first year after renal transplantation. MATERIAL AND METHODS: A retrospective, observational study was conducted of a cohort of patients of the 21st Century National Medical Center in Mexico of transplants performed from January 1, 2013 to December 31, 2017. A total of 649 met the inclusion criteria. Pre-transplant hemoglobin (Hb) levels were determined, as well as levels 1 month, 3, 6, 9, and 12 months after transplantation, and the prevalence of anemia and erythrocytosis was determined in each month. Descriptive analysis was performed with measures of central tendency and measures of dispersion. The statistical program SPSS version 25 was used. RESULTS: The mean pre-transplant Hb was 10.69 g/dL (standard deviation [SD] 2.04). One year after the renal transplant, Hb averaged 14.45 g/dL (SD 2.30), which meant an increase over the first year after renal transplantation of 3.76 g/dL. Pre-transplant anemia occurred in 73.1% of patients, and erythrocytosis in 0.1%; 12.9% of patients and 5.9% in erythrocytosis continued with anemia for a year. CONCLUSIONS: Renal transplantation allows Hb levels to recover in a multifactorial way; however, the persistence of anemia and erythrocytes creates a study challenge in any transplant unit, due to their prevalence of 12.9 and 5.9% respectively.

OBJECTIVES: The biochemical conditions in which patients arrive before renal transplantation (RT) are rarely evaluated; examples of them are found in the Dialysis Outcomes and Practice Patterns Study (DOPPS). The objective of our study was to ascertain the fulfillment of biochemical goals for patients on renal replacement therapy before RT. MATERIAL AND METHODS: Observational, retrospective study of patients who were on a RT protocol between 2012 and 2017 in 2 RT centers in Mexico. The records of 1188 patients with a history of RT and their lab results before transplantation were analyzed. Anthropometric values including hemoglobin, iron levels, calcium, phosphorus, parathyroid hormone, urea, creatinine, uric acid, and left ventricular ejection fraction were studied. All values were categorized as low, optimal, or high levels. RESULTS: The fulfillment of pretransplant biochemical objectives for elimination of azotemia (urea and creatinine) was achieved in 60% of the patients. Optimal values for calcium were found in 715 (64%) patients and optimal values for albumin were found in 690 (61.8%) patients. In the case of phosphorus, hemoglobin, uric acid, and parathyroid hormone, the optimal values were below 50%. CONCLUSIONS: It is essential to improve compliance with biochemical and clinical objectives for patients on renal replacement therapy (dialysis, hemodialysis) before RT. Only half of the variables were within the optimal range before surgical intervention took place.

BACKGROUND: Renal transplants (RTs) from deceased donors have increased in Mexico because of the high need of people with terminal kidney damage. The objective of this study is to determine the impact of cold ischemia time (CIT) on clinical outcomes in the deceased donor kidney transplant. METHODS: A retrospective, observational study of deceased donor RTs performed from 2013 to 2017 in the RT unit of the CMN Siglo XXI was completed. Data were collected from 202 patient records in this period; 7 clinical outcomes were determined, and logistic regression analysis was performed with CIT and extended criteria. The statistical package SPSS version 25 was used. RESULTS: No risk was observed for clinical outcomes with a CIT of 1080 minutes, risk of delayed function and medical complications was observed with a CIT of 1260 minutes, and risk of surgical complications was observed with a CIT of 1309 minutes. There was a correlation of 0.556 between the Maryland classification score and post-transplant medical complications. The extended criteria are related to risk for death with an odds ratio of 6.91 (95% CI, 2.27-21.01; P = .001) CONCLUSIONS: CIT continues to be an extremely important factor in renal graft survival and post-transplant clinical conditions. The extended criteria represent a considerable risk of death.

BACKGROUND: Dyslipidemia represents a trigger for cardiovascular complications, being in minimized renal transplantation (RT) or most of the occasions associated as something secondary to immunosuppression. The objective is to determine the pattern of cholesterol and triglyceride behavior in the first 12 months of post-transplant evolution and its relationship with age, sex of the recipient, and type of renal donor. MATERIALS AND METHODS: An observational, longitudinal study of RT carried out from 2013 to 2017 at the National Medical Center La Raza. In total, 328 records of patients with RT were analyzed. Cholesterol and triglyceride levels were studied over 12 months after renal transplantation; the association with sex, age of the renal recipient, and type of donor (live or deceased) was determined. Measures of central tendency and dispersion were made; the difference of means was established with a χ2 or Student t test. For risk, a bivariate analysis was performed with a significant value of P < .05. SPSS version 25 (IBM, Armonk, NY, United States) was used. RESULTS: The mean pretransplant cholesterol was within normal values (176.32, standard deviation [SD] 40.15 mg/dL), but triglycerides were not (158.36, SD 36.60 mg/dL). The pattern in both cases increased the values the first month after transplant to reach similar pretransplant levels in month 12. Cholesterol showed differences for month 12 in the group over 50 years (P = .022); like triglycerides in the 9th and 12th months (P = .026 and .003, respectively), values were higher in those over 50 years. DISCUSSION AND CONCLUSIONS: The pattern of cholesterol and triglyceride behavior is similar, even without understanding the reasons for the immediate post-transplant increase in month 1. There is no influence on the sex of the renal recipient nor on the type of donor. Only the age in recipients older than 50 years has a ratio of higher triglyceride values in months 9 and 12 and in cholesterol in the 12 months post-transplant.

BACKGROUND: Bone mineral disease after transplantation persists and is an issue that must be addressed owing to the cardiovascular impact it presents. The objective of this study is to present the behavior of calcium, phosphorus, and parathormone (PTH) before renal transplantation (RT) and throughout the 12 months after transplant surgery. METHODS: A longitudinal observational study of RT patients was performed from 2013 to 2017 in 2 renal transplant units in Mexico. In total, 1009 records of patients with RT were analyzed. Calcium, phosphorus, and PTH levels were studied before transplantation and for 12 months after. Central tendency and dispersion were measured, the difference of means was established with chi square or student t tests, and the significant value of P was set at <.05. We also used the SPSS statistical package, version 25. RESULTS: Phosphorus had a median pre-RT of 5.73, which decreased to 2.8 in the first month post-transplant and then increased to 3.41 at 12 months post-RT. The median PTH, on the other hand, started at 420.60 and decreased to 67.45. Calcium began at 9.04 and hit a plateau of 9.58 during month 12 after the surgical event. CONCLUSIONS: Of the 3 biochemical parameters evaluated, phosphorus was the one that most corrected itself after transplantation. Despite a tendency toward hypophosphatemia in the first month after transplantation, it began to normalize from month 6 on. Meanwhile, calcium was the biochemical value that changed the least after transplantation.

BACKGROUND: Transplantation depends on a donation from a living or deceased donor, with the latter ideally involving a multiorgan transplant. The objective of this study was to determine the factors that influence the attitudes of the population in Mexico toward being a donor. METHODS: We conducted an observational, cross-sectional study with a survey on the attitudes toward donation in the population of Mexico. The survey had 33 items on it regarding sociodemographic aspects and people's positions on the issues of organ and tissue donation. We used central tendency and dispersion averages and calculated the difference between groups using chi squares or the Student t test. We also used the statistical program SPSS version 25. RESULTS: The perception of respondents regarding organ and tissue donation (with 1064 people or 65.1% in favor) points to a lack of knowledge in Mexico. People do not talk about organ donation with their relatives and especially do not discuss their wishes in case of death (only 660 people indicated they had or 40.4%). There is a better attitude toward donation among younger respondents, women, single people, health personnel, people with higher incomes, Catholics, and those who do not have a hospitalized family member. CONCLUSIONS: It is necessary to provide more information about organ donation to people in Mexico. The opinion toward donation is generally favorable; however, there are multiple factors that influence opinions. Family members of patients in intensive care are the least willing to donate themselves or donate a relative's organs.

OBJECTIVE: Posttransplant anemia (PTA) in kidney recipients is a complication that has repercussions mainly of cardiovascular consequence. The objective of this study is to determine the prevalence of anemia, as well as the relationship between kidney recipient and donor sex, in the presence or absence of anemia at 12 months after kidney transplant (KT). MATERIAL AND METHODS: Observational, longitudinal study of KTs made over a 5-year period, from 2013 to 2017, in a renal transplant unit from La Raza National Health Care Medical Center. Three hundred twenty-eight records were analyzed. Hemoglobin (Hb) and the presence or absence of anemia according to the definition by the World Health Organization were analyzed. The association between kidney recipient sex and donor type (living or deceased) was evaluated. Analysis of central tendency and dispersion were performed and the mean difference was established with χ2 test or Student t test. Significance level was set at P < .05. RESULTS: The mean Hb (standard deviation) before KT was 10.38 (2.16) g/dL; Hb at 12 months was 14.47 (2.37) g/dL with an absolute increase of 4.09 g/dL. Before KT, male kidney recipients had a mean Hb of 10.54 (2.17) g/dL. At 12 months post-KT, mean Hb was 15.33 (2.25) with a change of 4.79 g/dL. Before KT, female kidney recipients had a mean Hb of 10.16 (2.13) g/dL. At 12 months post-KT, mean Hb was 13.31 (2.01) with a change of 3.15 g/dL. The difference between both sexes was 1.64 g/dL at the end of 12 months. Sixteen out of 152 (10.5%) patients had a serum creatinine (Cr) < 1.2 mg/dL and anemia; 36 out of 176 (20.5%) patients had a Cr ≥ 1.2 mg/dL and anemia (P = .014). In the bivariate logistic regression with an odds ratio of 2.047 (95% confidence interval, 1027-4078; P = .042) for higher Cr levels and the presence of persistent anemia. CONCLUSIONS: There is a prevalence of anemia in female kidney recipients and recipients of kidneys from deceased donors. There is a higher risk of persistent anemia in the case of patients with some degree of graft failure at 12 months.

INTRODUCTION: Renal transplantation (RT) has evolved to improve its functionality. Some factors have been little studied, one of which is hyperuricemia and its impact on renal graft function. The objective of this study is to determine the prevalence of complications of renal transplantation and its influence on hyperuricemia values in the first year of evolution. MATERIAL AND METHODS: The authors completed a retrospective, observational study of 2 RT units in Mexico from January 2013 to December 2017. In total, 1009 files met the inclusion criteria; the levels of uric acid (UA) and creatinine (Cr) were determined before transplantation and in months 1, 3, 6, 9, and 12 after transplantation. Descriptive analysis was performed with measures of central tendency, measures of dispersion, difference of means with Student t test, and SPSS version 25 (IBM, Armonk, NY, United States). RESULTS: The mean pretransplant UA was 6.24 mg/dL (standard deviation [SD] 1.97); per month was 4.73 mg/dL (SD 1.49). There is a difference in means between categorized groups of UA in the 5 post-RT moments (1, 3, 6, 9, and 12 months). A positive correlation of 0.41 to 0.47 was found with Spearman's test. The delayed function of the graft influenced in the first month after transplant in presenting hyperuricemia and acute dysfunction in month 6 showed that the rejection had no significance at any time. CONCLUSIONS: The relationship between the values of UA and Cr in the RT represents a moderate positive correlation; delayed graft function in the first month impacts the presence of hyperuricemia, as well as acute dysfunction at month 6 after transplantation.

BACKGROUND: The presence of acute renal injury has been associated with increased cardiovascular morbidity and mortality (sudden death and arrhythmias). OBJECTIVE: To know the frequency of heart rhythm disorders documented by Holter in patients in need of intermittent hemodialysis due to acute renal injury. MATERIAL AND METHODS: A prospective observational study was conducted including patients with a diagnosis of acute renal injury who received intermittent hemodialysis; demographic, clinical and laboratory data were collected from 28 patients. Monitoring was carried out through Holter before, during and after the hemodialysis session. Nonparametric statistics were used, with a significant value of p < 0.05. Risks were established with logistic regression. RESULTS: There was a significant difference in supraventricular extra systoles (82.1% vs. 57.1%), ventricular extra systoles (26.7% vs. 3.6%), and supraventricular tachycardia (6.7% vs. 3.6%). The rest of the rhythm alterations without significance. CONCLUSIONS: Intermittent hemodialysis is a factor associated with the appearance of heart rhythm disorders. The death of patients with acute renal injury and substitution was related to ventricular extra systole detected by transhemodialysis Holter.
INTRODUCCIÓN: La presencia de lesión renal aguda se ha asociado a unas mayores morbilidad y mortalidad de causa cardiovascular (muerte súbita y arritmias). OBJETIVO: Conocer la frecuencia de trastornos del ritmo cardiaco documentado por Holter en pacientes con necesidad de hemodiálisis intermitente por lesión renal aguda. MATERIAL Y MÉTODOS: Se realizó un estudio observacional, prospectivo, en pacientes con diagnóstico de lesión renal aguda que recibieron hemodiálisis intermitente; se recabaron datos demográficos, clínicos y de laboratorio de 28 pacientes. Se realizó monitoreo mediante Holter, previo, durante y posterior a la sesión de hemodiálisis. Se utilizó estadística no paramétrica, con un valor significativo de p < 0.05. Se establecieron riesgos con regresión logística. RESULTADOS: Hubo diferencia significativa en extrasístoles supraventriculares (82.1% frente a 57.1%), extrasístoles ventriculares (26.7% frente a 3.6%) y taquicardia supraventricular (6.7% frente a 3.6%). El resto de las alteraciones del ritmo no mostraron significancia. CONCLUSIONES: La hemodiálisis intermitente es un factor asociado a la aparición de trastornos del ritmo cardiaco. La muerte de los pacientes con lesión renal aguda y sustitución estuvo relacionada con la extrasístole ventricular detectada por Holter transhemodiálisis.

Resumen OBJETIVO: Identificar los factores asociados con los desenlaces fetales, maternos y renales en embarazadas con enfermedad renal crónica. MATERIALES Y MÉTODOS: Estudio observacional y prospectivo llevado a cabo en el Hospital de Ginecoobstetricia 4 del IMSS de 2016 a 2018 en pacientes embarazadas con enfermedad renal crónica, con parámetros bioquímicos (creatinina, urea) y desenlaces obstétricos; se excluyeron los casos incompletos. Por el tipo de población se usó estadística no paramétrica con mediana (tendencia central) y rango intercuartilar (dispersión). Para la comparación de medias se utilizó t de Student y Kruskal Wallis; los valores de p < 0.05 se consideraron estadísticamente significativos. Para establecer el riesgo se efectuó análisis bivariado. Se utilizó el programa estadístico SPSS 25. RESULTADOS: Se estudiaron 48 pacientes; de éstas 16 cursaron con preeclampsia. La cesárea fue la vía de finalización del embarazo más común en 32 de los 48 casos. En relación con los recién nacidos: 41 supervivieron, 22 de 41 fueron prematuros, 19 de 41 nacieron a término, 29 de 41 recién nacidos no experimentaron complicaciones. Se registró elevación de la creatinina de 0.28 mg/dL y descenso de la tasa de filtración glomerular de 9.67 mL/min. CONCLUSIONES: Se identificaron 4 factores. La maduración pulmonar y las enfermedades crónico-degenerativas representaron riesgo de prematurez. Los factores contibuyentes para el embarazo de término fueron: no cursar con preeclampsia y no tener eventos de hospitalización o infección. La enfermedad renal crónica influye de forma directa en desenlaces adversos para la madre y el feto; el embarazo influye en mayor deterioro renal.
Abstract OBJECTIVE: To know the factors associated with fetal, maternal and renal outcomes in known pregnant women with chronic kidney disease. MATERIALS AND METHODS: An observational, prospective study at the IMSS Hospital of Gynecobstetrics No. 4 from 2016 to 2018 of pregnant women with chronic kidney disease with biochemical parameters (creatinine, urea) and obstetric outcomes; Incomplete cases were excluded. For the type of population, non-parametric statistics were used with median (central tendency), interquartile range (dispersion), for the comparison of means, a student's "t" was used, with a significance of p < 0.05 and Kruskal Wallis. To establish risk, a bivariate analysis is performed. SPSS 25 statistical program. RESULTS: The obstetric results obtained were: 16/48 of the women with preeclampsia, caesarean section was the most common resolution in 32/48 cases. In relation to newborns, 41 survived, 22/41 with prematurity, 19/41 were full term, 29/41 newborns without complications. There was an elevation of 0.28 mg/dL creatinine and a decrease in the glomerular filtration rate of 9.67 mL/min. CONCLUSIONS: 4 factors were identified. Pulmonary maturation and chronic-degenerative diseases represented a risk for prematurity; Two influential factors for the termination of pregnancy were: not taking preeclampsia and having no hospitalization and/or infection events. chronic kidney disease directly influences both maternal and fetal adverse outcomes, and pregnancy also has an influence on greater renal impairment.
