Riesgo de mortalidad en candidemia en niños oncohematológicos: revisión sistemática / Mortality risk in candidemia in children with cancer and blood disorders: a systematic review

Introducción: La tasa de mortalidad de la candidemia es variable, pero puede estar influenciada por la patología de base, en especial aquella que condiciona la presencia de neutropenia. En niños con patología oncohematológica, son pocos los trabajos que han abordado la mortalidad relacionada a candidemias y sus factores asociados. Las preguntas que promueven esta revisión sistemática, son: ¿Cuáles son las características epidemiológicas, clínicas y de evolución de los pacientes pediátricos oncohematológicos con candidemia? ¿Cuál es la mortalidad relacionada con esta entidad? Materiales y métodos: Revisión sistemática de la literatura. Se utilizaron los siguientes términos de búsqueda: candidemia por Candida spp. y los siguientes filtros humanos, niños y adolescentes y patología oncohematológica. Se revisaron los artículos publicados en inglés, español o francés hasta el 21 de septiembre de 2023. Las referencias bibliográficas de los artículos incluidos se revisaron manualmente para identificar estudios relevantes adicionales. Resultados: Se encontraron 66 artículos. Del análisis cualitativo realizado en sus textos completos, quedaron finalmente 4 estudios que se consideró que cumplían con los criterios de inclusión. Todos los artículos seleccionados sumaron 191 pacientes con diversas patologías oncohematológicas. La presencia de accesos vasculares fue frecuente en esta serie y la no extracción del catéter venoso central fue el factor más prevalente entre los que fallecieron. El agente infectante predominante fue Candida no albicans y la mortalidad osciló entre el 11,3 y el 31% con una mediana de 25%. No fue posible establecer si la especie de Candida influía en la letalidad

Introduction: The mortality rate of candidemia is variable, but may be influenced by underlying diseases, especially those causing neutropenia. In children with cancer and blood disorders, few studies have addressed mortality related to candidemia and its associated factors. The questions that motivated this systematic review were: What are the epidemiological, clinical and outcome characteristics of pediatric cancer patients with candidemia? What is the mortality related to this condition? Materials and methods: Systematic review of the literature. The following search terms were used: Candida spp., candidemia, with the following filters: human, children and adolescents, and cancer and blood disorders. Articles published in English, Spanish, or French up to September 21, 2023 were reviewed. References of included articles were manually reviewed to identify additional relevant studies. Results: 66 articles were identified. From the qualitative analysis carried out on their full texts, 4 studies that were considered to meet the inclusion criteria were finally selected. The selected articles included a total of 191 patients with various types of cancer and blood disorders. The presence of vascular access was common in this series and failure to remove the central venous catheter was the most prevalent factor among those who died. The predominant infectious agent was non-albicans Candida and mortality ranged from 11.3% to 31% with a median of 25%. It was not possible to establish whether Candida species influenced mortality.

Riesgo de mortalidad en infecciones invasivas por Mucor SPP. en niños con enfermedades hemato-oncológicas: revisión sistemática / Mortality risk of invasive Mucor spp. infections in children with cancer: A systematic review

Los estudios sobre la infección fúngica invasiva (IFI) por Mucor spp. en pacientes pediátricos con patología hematooncológica, son de baja solidez científica, lo que dificulta conocer en profundidad sus características y evolución. Con el objetivo de analizar la evolución fatal de esos pacientes, se llevó a cabo esta revisión sistemática (RS). Material y métodos: La búsqueda bibliográfica se realizó con fecha 23 de marzo de 2023, en las principales bases de datos (Medline (a través de Pubmed), Embase (a través de Embase-Elsevier), The Cochrane Library (a través de Wiley), Cinahl (a través de Ebsco HOST), SCI-EXPANDED, SciELO (a través de la WOS) y Scopus (a través de Scopus-Elsevier), libre (mediante el motor Google) y revisando las citas de los artículos incluidos. Resultados: Se rescataron 1393 artículos, de los cuales se descartaron 1386 por diversas razones. Mediante el análisis de los textos completos, finalmente se incluyeron 7 estudios. Todos los estudios eran series de casos (nivel 4). La mediana de la frecuencia de muerte observada fue de 36,6% (Q1 20% - Q347%). Conclusiones: Esta RS mostró en niños con patología hemato-oncológica, que la mortalidad por IFI por Mucor spp. alcanzó a casi un tercio de los pacientes (AU)

Studies on invasive fungal infection (IFI) by Mucor spp. in pediatric patients with cancer have a low level of evidence, which makes it difficult to elucidate its characteristics and progression. To analyze the fatal outcome of these patients, this systematic review (SR) was conducted. Material and methods: A literature search was carried out on March 23, 2023, in the following main databases (Medline (via Pubmed), Embase (via Embase-Elsevier), The Cochrane Library (via Wiley), Cinahl (via Ebsco HOST), SCI-EXPANDED, SciELO (via the WOS) and Scopus (via Scopus-Elsevier). Additionally, a complementary search was carried out using free search engines (such as Google) and by reviewing the references of the included articles. Results: A total of 1393 articles were retrieved, of which 1386 were excluded for various reasons. After a thorough analysis of the full-text articles, 7 studies were ultimately included in the review. All studies were case series (level 4). The median observed death rate was 36.6% (IQR, 20% - 47%). Conclusions: This SR showed that in children with hematological-oncological disease, mortality due to IFI by Mucor spp. affected almost one third of the patients (AU)

Mortalidad en niños con bacteriemia por Stenotrophomonas maltophilia: revisión sistemática / Mortality in children with Stenotrophomonas maltophilia-related bacteremia: A systematic review

Introducción: En los niños, la bacteriemia por Stenotrophomonas maltophilia es considerada una complicación severa y asociada a una elevada mortalidad. Con el objetivo de conocer la mortalidad asociada a esa condición, se realizó una revisión sistemática de la literatura. Material y métodos: Se aplicó una estrategia de búsqueda bibliográfica con las palabras clave: bacteriemia por Stenotrophomonas maltophilia, niños y adolescentes como únicos filtros. Se informan la mediana y los valores intercuartílicos de la frecuencia de la mortalidad reportada por los estudios incluidos. Resultados: Se identificaron 165 estudios potencialmente útiles. De ellos, se seleccionaron finalmente, 9 estudios para ser incluidos. La incidencia de mortalidad a consecuencia de una bacteriemia por S.maltophilia fue del 25%; Q25: 11­Q75: 36; rango: 6,06 a 40,6. Consideraciones finales: La bacteriemia por Sm tuvo un alto porcentaje de mortalidad en especial en pacientes con patología subyacente y uso de procedimientos invasivos y el uso inadecuado de antibióticos empíricos (AU)

Introduction: In children, Stenotrophomonas maltophilia-related bacteremia is considered a severe complication associated with high mortality. With the aim to determine the mortality associated with this condition, a systematic review of the literature was conducted. Material and methods: A literature search strategy was applied using the keywords: bacteremia due to Stenotrophomonas maltophilia, children, and adolescents as the only filters. The median and interquartile ranges of the mortality rates described in the studies included are reported. Results: A total of 165 potentially useful studies were identified, of which nine were finally selected to be included in the analysis. The incidence of S.maltophilia bacteremia-related mortality was 25%; Q25: 11­Q75: 36; range: 6.06 to 40.6. Final considerations: S.maltophilia-related bacteremia was associated with a high mortality rate especially in patients with an underlying disease, when invasive procedures were performed, and when emperical antibiotics were inadequately used (AU)

Síndrome inflamatorio multisistémico pediátrico (SIMS) asociado con el SARS-CoV-2: Un estudio de cohorte retrospectivo / SARS-CoV-2-associated pediatric multisystemic inflammatory syndrome: A retrospective cohort study

Introduccion: El Síndrome inflamatorio multisistémico pediátrico (SIMS) asociado con el SARS-CoV-2 es una enfermedad aguda acompañada de un síndrome hiperinflamatorio, con falla multiorgánica y shock, asociada a la infección por SARS CoV2, que produce alta morbilidad en la población pediátrica, que hasta el momento es la afectada por este síndrome. Objetivo: Evaluar las características diferenciales del síndrome multisistémico inflamatorio asociado al SARS-COV-2 (SIMS) en niños. Métodos: se realizó un estudio de cohorte retrospectivo. La definición de SIMS se basó en los criterios de la OMS. Los pacientes con COVID-19 relacionados temporalmente se incluyeron como controles. Resultados: se incluyeron 25 pacientes con SIMS y 75 controles. El modelo de regresión logística múltiple de las variables que mostraron ser significativas en el análisis univariado reveló que la edad ≥ 2 años (OR 24,7; IC del 95%: 1,03 -592,4; P = 0,048), la linfopenia (OR 9,03; IC del 95%: 2,05-39,7; P = 0,004), y el recuento de plaquetas <150x109 / L (OR 11,7; IC del 95%: 1,88-75,22; P = 0,009) se asociaron significativamente con SIMS. La presencia de una enfermedad subyacente pareció reducir el riesgo de SIMS (OR 0,06; IC del 95%: 0,01-0,3). Conclusión: El SIMS fue más común en pacientes mayores de 2 años y en aquellos con linfopenia o trombocitopenia. La enfermedad subyacente parece reducir el riesgo del mismo. (AU)

Introduction: SARS-CoV-2-associated pediatric multisystemic inflammatory syndrome (PMIS) is an acute disease accompanied by a hyperinflammatory syndrome, with multiorgan failure and shock associated with SARS CoV2 infection, producing high morbidity in the pediatric population, which so far is affected by this syndrome. Objective: To evaluate the differential characteristics of SARS-COV-2-associated PMIS in children. Methods: A retrospective cohort study was conducted. The definition of PMIS was based on WHO criteria. Patients with temporally related COVID-19 were included as controls. Results: 25 patients with PMIS and 75 controls were included. A multiple logistic regression model of the variables shown to be significant in univariate analysis revealed that age ≥ 2 years (OR 24.7; 95% CI: 1.03 -592.4; P = 0.048), lymphopenia (OR 9.03; 95% CI 2.05-39.7; P = 0.004), and platelet count < 150x109/L (OR 11.7; 95% CI: 1.88-75.22; P = 0.009) were significantly associated with PMIS. The presence of an underlying disease appeared to reduce the risk of PMIS (OR 0.06; 95% CI: 0.01-0.3). Conclusion: PMIS was more common in patients older than 2 years and in those with lymphopenia or thrombocytopenia. Underlying disease appears to reduce the risk of SMIS.(AU)

Uterine muscle relaxant drugs for threatened miscarriage.

BACKGROUND: Miscarriage is the spontaneous loss of a pregnancy before the fetus is viable. Uterine muscle relaxant drugs have been used for women at risk of miscarriage in the belief they relax uterine muscle, and hence reduce the risk of miscarriage. OBJECTIVES: To assess the effects for the woman and her baby of uterine muscle relaxant drugs when used for threatened miscarriage. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group Trials Register (4 May 2004), and the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 2, 2004). SELECTION CRITERIA: Randomised trials were included, and quasi-randomised trials were excluded. The participants were women with a pregnancy of less than 20 weeks' gestation having a threatened miscarriage. The interventions were any uterine muscle relaxing drugs (including tocolytic and antispasmodic agents) compared with either placebo or no drug. Primary outcomes for the review were miscarriage: defined as spontaneous pregnancy loss before fetal viability, baby death (stillbirth or neonatal death) and maternal death. DATA COLLECTION AND ANALYSIS: Both review authors independently assessed studies for eligibility and trial quality, and extracted data. MAIN RESULTS: One poor quality trial (170 women) was included. This compared a beta-agonist with placebo. There was a lower risk of intrauterine death associated with the use of a beta-agonist (relative risk (RR) 0.25, 95% confidence interval (CI) 0.12 to 0.51). Preterm birth was the only other outcome reported (RR 1.67, 95% CI 0.63 to 4.38). AUTHORS' CONCLUSIONS: There is insufficient evidence to support the use of uterine muscle relaxant drugs for women with threatened miscarriage. Any such use should be restricted to the context of randomised trials.

Evaluation of methods used in the prediction of hypertensive disorders of pregnancy.

Several methods used in the prediction of hypertensive disorders of pregnancy (HDP) were evaluated with statistical techniques. Only cohort studies were considered. The data reviewed show that platelet count, hematocrit, serum uric acid, and microalbuminuria are poor predictors of HDP. Mean arterial pressure predicts transient hypertension rather than preeclampsia. Fibronectin, urinary calcium excretion, roll-over test, and Doppler ultrasound showed contradictory and nonconclusive findings among the different authors. Isometric exercise test showed high predictive values but only two studies have been performed. Angiotensin II sensitivity was the test that showed the best predictive values but it is useless in clinical practice. In conclusion, currently, there is no test that fulfills all criteria established to be a good predictor of hypertensive disorders of pregnancy. The search for an adequate method for the screening of HDP with a high sensitivity, inexpensive, and easy to perform should still be a priority in future investigations.

Anidulafungina en niños: Experiencia en niños con trasplante de médula ósea / Anidulafungin in children: experience in children undergoing bone marrow transplantation

Introducción: Las infecciones fúngicas invasoras (IFI) son un problema de salud cada vez mayor, y se asocian con una alta morbilidad y mortalidad. Las nuevas opciones terapéuticas, tales como las equinocandinas y entre estos anidulafungina, se han utilizado en la población adulta, pero en pacientes pediátricos con trasplante de médula ósea la experiencia es escasa. Objetivo: El objetivo de este estudio descriptivo es presentar nuestra experiencia con el uso de la anidulafungina como profilaxis o tratamiento en pacientes con trasplante de médula ósea. Material y métodos: Entre enero hasta junio 2016, 29 pacientes trasplantados de médula ósea recibieron anidulafungina como profilaxis o tratamiento de infecciones fúngicas invasivas (IFI) probadas, probables o posibles. En todos los casos se monitorizó el valor de transaminasas, bilirrubina, creatinina y el recuento de glóbulos blancos al inicio y al final del tratamiento. Resultados: La anidulafungina se administró por vía intravenosa en una dosis de carga de 3 mg/kg/día, seguida de 1,5 mg/kg/día durante una mediana (Md) de 16 días (intervalo intercuartílico: 2-65 d). La Md de la edad de los pacientes fue de 97 meses (rango: 6-211m). La anidulafungina fue indicada como tratamiento en 7 casos (24%) y como profilaxis primaria o secundaria,en 22 (76%). En un paciente se confirmó microbiológicamente una IFI, por Candida albicans. Las Md de los parámetros bioquímicos en el inicio del tratamiento y al final, fueron: transaminasas GOT 29,5 U/l y 32 U/l (p 0,44); bilirrubina 0,35 y 0,30 mg/dL (p: 0,20); creatinina, 0,52 y 0,60 mg/dl (p:0,67). El recuento de glóbulos blancos mostró una gran variabilidad debido a la enfermedad subyacente, pero la diferencia de su valor entre el inicio y al final de la administración del fármaco, no fue significativo: Md 2810 células/mm3 y 5160 células/mm3, respectivamente (p: 0,07). Ninguno de los pacientes tuvo eventos adversos o murieron por causas relacionadas con anidulafungina. En el seguimiento a 30 días no se registró recaída de la infección o mortalidad relacionada a la droga. Conclusiones: Los resultados de nuestra serie sugieren que la anidulafungina podría ser una opción para la profilaxis o el tratamiento de las IFI en los niños con trasplante de médula ósea. Se requieren más estudios para confirmar estas observaciones (AU)

Introduction: Invasive fungal infections (IFI) are an increasing health problem associated with high morbidity and mortality. New treatment options, such as echinocandins and among these anidulafungin, have been used in the adult population, but experience in children undergoing bone marrow transplantation is scarce. Aim: The aim of this descriptive study is to present our experience with the use of anidulafungine as prophylaxis or treatment in patients undergoing bone marrow transplantation. Material and methods: Between January and June 2016, 29 patients who underwent bone marrow transplantation received anidulafungin as prophylaxis against or treatment for confirmed, probable, or possible (IFI). In all cases transaminase, bilirubin, and creatinine levels as well as total white blood cell count were monitored at treatment initiation and completion. Results: Anidulafungine is administered intravenously in a loading dose of 3 mg/kg/day, followed by 1.5 mg/kg/day for a mean of 16 days (interquartile range: 2-65 d). Mean age of the patients was 97 months (range: 6-211m). Anidulafungine was used as treatment in 7 cases (24%) and as primary or secondary prophylaxis in 22 (76%). IFI was microbiologically confirmed to be Candida albicans in one patient. Mean biochemical parameters at treatment onset and completion were: transaminases AST 29.5 U/l and 32 U/l (p 0.44); bilirubin 0.35 and 0.30 mg/dL (p 0.20); creatinine, 0.52 and 0.60 mg/dl (p : 0.67). White blood cell count was highly variable due to the underlying disease; however, the difference between values at treatment initiation and completion were not significant: Mean 2810 cells/mm3 and 5160 cells/mm3, respectively (p: 0.07). None of the patients had adverse effects or died because of anidulafungin-related causes. At 30 days of follow-up no relapse of infection or drug-related mortality was observed. Conclusions: The results in our series suggest that anidulafungin is an option for the prophylaxis against or treatment of IFI in children undergoing bone marrow transplantation. Further studies are necessary to confirm these findings (AU)

Utilidad de Trimetoprima-sulfametoxazol en épocas de S. aureus meticilino resistente de la comunidad / Usefulness of trimethoprim-sulfamethoxazole in times of community-acquired methicillin-resistant S. aureus.

Trimetoprima-sulfametoxazol (TMP-SMX) tiene actividad in vitro contra cepas de Staphylococcusaureus, en especial las cepas resistentes a la meticilina de la comunidad (SAMR-Co), Éste es considerado un antibiótico útil debido a su bajo costo, amplio espectro y posibilidad de administración por vía oral dada su adecuada biodisponibilidad y sabor agradable. Se realizó esta revisión narrativa de la literatura para evaluar el uso de TMP-SMX en comparación con otras opciones disponibles en el tratamiento de las infecciones por SAMR-Co en niños (AU)

Trimethoprim/sulfamethoxazole (TMP-SMX) has in vitro activity against Staphylococcus aureus, especially against community-acquired methicillin-resistant (CAMR) strains. It is considered to be a useful antibiotic because of its low cost, broad spectrum, and possibility of oral administration because of its adequate bioavailability and agreeable flavor. A review of the literature was performed to evaluate the use of TMP-SMX compared to available options for the treatment of CAMR infections in children (AU)

Is routine use of episiotomy justified?

Episiotomy, one of the most common surgical procedures, was introduced in clinical practice in the eighteenth century without having strong scientific evidence of its benefits. Its use was justified by the prevention of severe perineal tears, better future sexual function, and a reduction of urine and fecal incontinence. With regard to the first assumption, the evidence that is based on five randomized controlled trials shows a 9% reduction in severe perineal tears in the selective use of episiotomy, but this effect fluctuates between a 40% reduction and a 38% increase. In relation to long-term effects, women in whom management includes routine use of episiotomy have shown poorer future sexual function, similar pelvic floor muscle strength, and similar urinary incontinence in comparison with women in whom episiotomy is used in a selective manner. In summary, there is no reliable evidence that routine use of episiotomy has any beneficial effect; on the contrary, there is clear evidence that it may cause harm such as a greater need for surgical repair and a poorer future sexual capability. In view of the available evidence the routine use of episiotomy should be abandoned and episiotomy rates > 30% do not seem justified.

What does an elevated mean arterial pressure in the second half of pregnancy predict--gestational hypertension or preeclampsia?

OBJECTIVE: The purpose of this study was to determine the predictive value of elevated mean arterial pressure in the second half of pregnancy for both preeclampsia and gestational hypertension. STUDY DESIGN: This was a cohort of 588 nulliparous pregnant women studied prospectively from the twentieth week until delivery. Mean arterial pressure was obtained by means of a random-zero sphygmomanometer at 20, 26, and 31 weeks of gestation. The best cutoff point for the determination of predictive values was established by a receiver-operator characteristic curve. RESULTS: Patterns of mean arterial pressure throughout pregnancy were different between preeclamptic and gestational hypertensive women. Receiver-operator characteristic curves for mean arterial pressure showed better predictive capacity for gestational hypertension than for preeclampsia. Sensitivity of mean arterial pressure to predict preeclampsia ranged between 39% and 48%, whereas for prediction of gestational hypertension it varied from 72% to 92%. Specificities for both groups were moderate (60% to 86%). Positive predictive values were low for all groups (5% to 33%). CONCLUSION: Elevated mean arterial pressure in the second half of pregnancy is a good predictor of gestational hypertension but is a poor predictor of preeclampsia.

Agreement between different frequencies of measurements in ambulatory blood pressure monitoring.

The purpose of this study was to determine the degree of agreement among different frequencies of blood pressure measurements (FoM) in 24-hour ambulatory blood pressure monitoring (ABPM) in their ability to obtain useful clinical information. ABPM records were obtained with a Del Mar IV Avionics device from 49 hospitalised preeclamptic women with a FoM of 7 per hour (high-FoM). With these records, we simulated two sets of data as if measurements had been recorded at a rate of 1 measurement per hour (low-FoM) and of 2 per hour (medium-FoM). Diastolic blood pressure > 89 mmHg defined hypertension and > 109 mmHg, severe hypertension The median and 25th and 75th centiles for the differences in hypertensive rate detected (expressed as percentage points) between lowFoM vs. high-FoM was 0.00 (- 3.4-3.00) and between medium-FoM vs. high-FoM,- 1.04 (- 3.7-1.5). The agreement in the detection of severely affected patients was 85% (CI 95%: 74-96) between low-FoM and high-FoM and 87% (CI 95%: 77-98), between medium-FoM and high-FoM. Average blood pressure was similar in the three FoMs studied at day-time and night-time. We did not find any strong argument to perform ABPM at a high-FoM. Lower FoM are more comfortable for the patient and could reduce equipment deterioration, while providing equivalent information to that supplied by high-FoM.

[Preterm delivery: detection of risks and preventive treatment]. / El parto pretérmino: detección de riesgos y tratamientos preventivos.

Every year around the world some 13 million premature children are born. Most of these children are born in developing countries, and they account for the largest share of perinatal morbidity and mortality. This review study analyzed scientifically validated data on interventions to prevent at least some portion of these preterm deliveries and to lessen their impact on neonatal health. The Cochrane and MEDLINE bibliographic databases were consulted. Fifty review pieces and research articles were studied, relating to the following aspects of preterm delivery: risk factors and early detection of the risk of preterm delivery; preventing the risk of preterm delivery; treating preterm delivery once it has begun; and preventing neonatal respiratory distress syndrome. There were few successful approaches to the prediction, prevention, or early detection of the threat of preterm delivery. The only measures that can be recommended for all pregnant women are screening for and treating asymptomatic bacteriuria as a part of prenatal check-ups. Screening for bacterial vaginosis and treating it reduce the incidence of preterm births in pregnant women with a history of premature delivery. In addition, prophylactic cerclage decreases the incidence of premature births in pregnant women who have had more than three preterm births. To treat a delivery that starts early, with or without premature membrane rupture, the interventions that have proved to be effective are administering betamimetics to the parturient woman in order to delay delivery for 48 hours, and using indomethacin for the same purpose, as the second-choice drug. The prenatal administration of corticosteroids to the pregnant woman can induce lung maturation in the fetus and reduce respiratory distress syndrome and ventricular hemorrhage, thus decreasing neonatal mortality. There is a need to continue and support basic and epidemiological research in order to develop new knowledge on the causes and mechanisms of preterm delivery and on preventing the morbidity and mortality that preterm delivery produces.

High-dose gammaglobulin (IVIG) followed by intrauterine transfusions (IUTs): a new alternative for the treatment of severe fetal hemolytic disease.

Intrauterine fetal transfusion is currently the therapy of choice in cases of severe anti-D isoimmunisation. However, its efficacy is reduced in patients with early severe hydrops fetalis due to the technical difficulties in performing this procedure before 20 weeks' gestation. The purpose of this study was to determine whether early onset of high-dose gammaglobulin therapy followed by intrauterine transfusions (IUTs) is more effective than IUTs alone in the treatment of very severe isoimmunised fetuses. The population studied in this retrospective clinical research was assigned to one of the following two groups: 1) Gamma group: 30 patients receiving gammaglobulin therapy before 21 weeks' gestation and IUTs after 20 weeks; or 2) IUT group: 39 patients receiving IUT treatment starting at a gestational age of 20-25 weeks. Both groups were statistically similar regarding history of perinatal deaths and anti-D antibody titers. The number of hydropic fetuses at the first IUT and of fetal deaths were significantly higher in the IUT than in the Gamma group. No significant differences were observed between the groups in fetal hematocrit at first IUT and at birth. However, the percentage of severely anemic fetuses was higher in the IUT group. Fetal mortality rate was 36% less in the Gamma group. Our results suggest that high-dose gammaglobulin therapy followed by IUTs may improve fetal survival in these severe cases. Further randomised clinical trials are needed to confirm these results.

Embarazo exitoso en una paciente en hemodiálisis crónica / Successful pregnancy in a chronic hemodialysis patient

Es presentado el embarazo exitoso en una paciente con IRC en hemodiálisis crónica. ella fue previamente transplantada rechazando el injerto. Inmediatamente fue reincorporada al tratamiento de diálisis crónica hallándose más tarde embarazada, arribando al parto en enero de 1983. Nació un feto vivo, prematuro, sin anormalidades congénitas. Se presentan a discusión las facetas adoptadas en el seguimiento de la paciente ys e efectúa una revisión de la bibliografía mundial. Concluímos que, aunque siempre la presencia de embarazo en una paciente en hemodiálisis crónica es un riesgo, esta paciente deber ser considerada en particular, individualizando el tratamiento dialítico.
