RESUMEN
Resumen Objetivo: Establecer la prevalencia de hipertensión arterial (HTA) en los pacientes pediátricos hospitalizados en un centro hospitalario de tercer nivel de Medellín, Colombia, durante seis años. Métodos: Se hizo un estudio descriptivo de corte transversal que revisó información retrospectiva obtenida de los registros de las historias clínicas de pacientes menores de 18 años hospitalizados en el Hospital Pablo Tobón Uribe de Medellín, Colombia. Resultados: De un total de 382 pacientes pediátricos hospitalizados en el periodo estudiado se obtuvo una prevalencia de HTA del 30.6%, la de hipertensión sistólica fue 23.6% y la de diastólica 20.7%. Los niños menores de cinco años, el uso de vancomicina y la estancia en cuidado crítico aumentan significativamente el riesgo de presentar hipertensión durante la hospitalización. Conclusiones: En pediatría la frecuencia de HTA en pacientes hospitalizados es elevada, mayor a la prevalencia reportada en pacientes ambulatorios. Se debe reconocer el grupo de mayor riesgo y los factores potencialmente modificables, así como definir el inicio de tratamiento de forma oportuna. Las complicaciones son bajas, excepto la hipertrofia ventricular izquierda, por lo que es necesario un seguimiento a largo plazo.
Abstract Objective: To establish the prevalence of arterial hypertension in pediatric patients hospitalized in a tertiary hospital center in Medellin, Colombia for 6 years. Methods: A descriptive cross-sectional study was carried out that reviewed retrospective information obtained from the clinical records of patients under 18 years of age hospitalized at the Pablo Tobón Uribe Hospital in Medellín. Results: From a total of 382 pediatric patients hospitalized in the studied period, a prevalence of hypertension of 30.6% was found. Systolic hypertension prevalence was 23.6% and diastolic 20.7%. Age under 5, treatment with vancomycin and critical care admission increased the risk of being hypertensive during hospitalization. Conclusions: In children the frequency of hypertension in hospitalized patients is higher than the prevalence reported in outpatients. The highest risk group and potentially modifiable factors must be recognized and treatment administered in a timely manner. Secondary complications are low, except for left ventricular hypertrophy, which requires long-term follow-up.

Abstract BK virus nephropathy in kidney transplantation is widely recognized as an important cause of graft dysfunction and loss. In the case of transplants of organs other than kidney, BK virus nephropathy in native kidneys has been recognized as a cause of chronic kidney disease, which is related with immunosuppression; however, the diagnosis is usually late because the renal dysfunction is attributed to other causes, such as toxicity by anticalcineurinic drugs, interstitial nephritis due to medications, hemodynamic changes, diabetes, hypertension, etc. We report a case of BK virus nephropathy in a patient who underwent heart transplantation due to peripartum cardiomyopathy. The kidney biopsy reported active chronic tubulointerstitial nephritis associated with late stage polyomavirus nephritis and the blood viral load for BK virus was positive (logarithm 4.5). The immunosuppressive treatment was reduced, and after two years of follow-up, the patient had stable renal function with a serum creatinine of 2.5 mg/dL (GFR of 23.4 mL/min/1.73m2). We recommend that the BK virus be considered as a cause of renal dysfunction in heart transplant recipients, with the aim of detecting its replication in time to reduce immunosuppressive therapy before irreversible compromise of renal function may manifest.
Resumo A nefropatia pelo vírus BK no transplante renal é amplamente reconhecida como uma importante causa de disfunção e perda do enxerto. No caso de transplantes de órgãos que não sejam rins, a nefropatia pelo vírus BK em rins nativos tem sido reconhecida como uma causa de doença renal crônica, que está relacionada com imunossupressão; entretanto, o diagnóstico é geralmente tardio porque a disfunção renal é atribuída a outras causas, tais como toxicidade por drogas anticalcineurínicas, nefrite intersticial devido a medicamentos, alterações hemodinâmicas, diabetes, hipertensão, etc. Relatamos um caso de nefropatia pelo vírus BK em um paciente que foi submetido a transplante cardíaco devido à cardiomiopatia periparto. A biópsia renal relatou nefrite túbulo-intersticial crônica ativa associada à nefrite por poliomavírus em estágio avançado e a carga viral sanguínea para o vírus BK foi positiva (logaritmo 4,5). O tratamento imunossupressor foi reduzido, e após dois anos de acompanhamento, o paciente apresentava função renal estável com creatinina sérica de 2,5 mg/dL (TFG de 23,4 mL/min/1,73m2). Recomendamos que o vírus BK seja considerado como uma causa de disfunção renal em receptores de transplante cardíaco, com o objetivo de detectar sua replicação a tempo de reduzir a terapia imunossupressora antes que um comprometimento irreversível da função renal possa se manifestar.

Abstract Introduction: The numbers of SARS-CoV-2 infection in the pediatric population are low so far. There is limited information about the behavior of SARS-CoV-2 in a pediatric patient with chronic kidney disease. Objective: To formulate informed recommendations to the prevention, diagnosis, and management of SARS-CoV-2 infection in pediatric patients with kidney disease or acute kidney injury associated with COVID-19 in Colombia. Methodology: A rapid systematic review was performed in Embase and Pubmed databases and scientific societies, to answer questions prioritized by clinical experts in pediatric nephrology. The quality of the evidence was evaluated with validated tools according to the type of study. The preliminary recommendations were consulted by an expert group. The agreement was defined when approval was obtained from at least 70% of the experts consulted. Results: A response was obtained from ' 9 experts in pediatric nephrology in Colombia, who declared the conflict of interest before the consultation. The range of agreement for the recommendations ranged from 78.9% to '00%. The recommendations did not require a second consultation. Conclusion: The evidence-based recommendations for the management of a patient with kidney disease and COVID-19 in the Colombian context are presented.

Abstract Renal crisis is a complication with significant morbidity and mortality in scleroderma patients and a rare entity in kidney transplantation. It may present with highly variable clinical manifestations, mainly arterial hypertension, acute kidney failure and multisystemic involvement. Following is the report of a patient with late reoccurrence of scleroderma crisis in kidney transplantation, who was given successful treatment with angiotensin-converting enzyme inhibitors.(Acta Med Colomb 2020; 45. DOI:https://doi.org/10.36104/amc.2020.1215).
Resumen La crisis renal es una complicación con importante morbilidad y mortalidad en pacientes con esclerodermia y una rara entidad en trasplante renal, que se puede presentar con manifestaciones clínicas muy variables, principalmente hipertensión arterial, falla renal aguda y compromiso multisistémico. A continuación se reporta el caso de una paciente con recurrencia tardía de la crisis esclerodérmica en el trasplante renal, que recibió tratamiento exitoso con inhibidores de la enzima convertidora de angiotensina.(Acta Med Colomb 2020; 45.

RESUMEN La linfohistiocitosis hemofagocítica (LHH) posterior al trasplante renal hace referencia a un estado hiperinflamatorio grave, asociado a la activación no controlada de los linfocitos T citotóxicos y macrófagos por causa infecciosas y/o secundaria al tratamiento inmunosupresor. Las causas más prevalentes dentro de las infecciones son la histoplasmosis, la tuberculosis y las infecciones por virus herpes. Se caracteriza por fiebre, organomegalias, citopenias, hiperferritinemia, hipertrigliceridemia y/o hipofibrinogenemia; puede acompañarse con hemofagocitosis documentada en la médula ósea, el hígado u otros órganos. Su curso puede ser fulminante con progresión a falla multisistémica y la muerte. El tratamiento va enfocado a controlar tempranamente la causa desencadenante, reducir la inmunosupresión y controlar la inflamación. En pocos casos es necesario el uso de otros inmunosupresores, quimioterapia o, en situaciones muy seleccionadas, se puede requerir el trasplante de médula ósea.
SUMMARY Hemophagocytic lymphohistiocytosis (HLH) in renal transplant recipients is a life-threatening hyper-inflammatory syndrome; associated with uncontrolled activation of cytotoxic T-lymphocytes and macrophages due to infections or immunosuppressive therapy. Histoplasmosis, tuberculosis and herpes virus infection are among the leading infectious causes. It is characterized by fever, organomegaly, cytopenia, hyperferritinemia, hypertrigiceridemia and/or hypofibrinogenemia; which may be accompanied by hemophagocytosis in bone marrow, liver or other organs. HLH can follow a rapidly fatal course, with progression to multisystemic failure and death. The treatment is based on early control of the triggering cause, reducing immunosuppression and stop the inflammatory process. In some cases, is necessary to use other immunosuppressant, chemotherapy and in a very few cases, a bone marrow transplant may be required.
