Eficacia y seguridad de un compuesto de ácidos grasos hiperoxigenados en la mejora de la microcirculación de la púrpura fulminante en pacientes pediátricos con sepsis: estudio piloto / Efficacy and safety of a hyperoxygenated fatty acid compound in improving the microcirculation of purpura fulminans in paediatric patients with sepsis: a pilot study

Introducción La púrpura fulminante (PF) es una complicación grave de la sepsis resultado de un conjunto de alteraciones caracterizadas por el desarrollo de lesiones hemorrágicas equimóticas y necrosis de la piel. Objetivo Analizar la eficacia y la seguridad de la aplicación tópica de un compuesto de ácidos grasos hiperoxigenados (AGHO) en la microcirculación de la PF en pacientes pediátricos afectados de sepsis. Material y métodos Se llevó a cabo un estudio prospectivo cuasiexperimental pretest-posttest de un solo grupo en una Unidad de Cuidados Intensivos Pediátrica (UCIP). Se incluyeron en el estudio pacientes con PF de 0 a 18 años. Para evaluar la efectividad del producto objeto de evaluación en la microcirculación de las lesiones por PF se determinaron los valores de oximetría somática antes y después de la aplicación de AGHO cada 4h durante los 3 primeros días de ingreso de los pacientes. Resultados Se reclutaron 4 pacientes, con una mediana de edad de 98 meses. Las lesiones purpúricas que se midieron estaban ubicadas, sobre todo, en ambos pies y manos y, en 2 pacientes, también en los maléolos laterales y gemelos de ambas extremidades inferiores. Se obtuvieron un total de 225 mediciones, observando unas puntuaciones medias preintervención de 71,17±15,65% versus los 73,68±14,83% postintervención. Se objetivó significación estadística (p<0,001) al comparar las mediciones pre- y postintervención. Conclusiones La aplicación precoz y continuada de AGHO en el manejo de la PF por sepsis es una práctica eficaz y segura en los casos de población pediátrica analizada. En más de la mitad de los episodios analizados se objetivó un aumento de microcirculación tisular tras la aplicación de los AGHO, sin eventos adversos. (AU)

Introduction Purpura fulminans (PF) is a serious complication of sepsis resulting from a set of alterations characterised by the development of ecchymotic haemorrhagic lesions and skin necrosis. Aim To analyse the efficacy and safety of the topical application of HOFA compound, in the cutaneous microcirculation of PF lesions in paediatric patients affected by sepsis. Material and methods A prospective quasi-experimental pre-test/post-test single-group conducted in a Paediatric Intensive Care Unit of a third level hospital was performed. Paediatric patients aged 0-18 years with sepsis were included. Somatic oximetry values were measured before and after application of HOFAs every 4hours over the first three days of the patients’ hospitalisation. Patient's socio-demographic and clinical variables and somatic oximetry by placing a sensor for measuring tissue perfusion on the area with PF were determined. Results Four patients were recruited, with a median age of 98 months. The purpuric lesions measured were mainly located on both feet and hands and, in two patients, also on the lateral malleoli and calves of both lower extremities. A total of 225 measurements were obtained, with mean pre-intervention scores of 71.17±15.65% versus 73.68±14.83% post-intervention. Statistical significance (p<0.001) was observed upon comparison of the pre- and post-intervention measurements. Conclusions Early and continued application of HOFAs in the management of sepsis-induced PF is an effective and safe practice in the cases analysed. In more than half of the episodes analysed, an increase in tissue microcirculation was observed after the application of HOFAs, with no adverse events. (AU)

Renal histological findings in a patient with acute renal injury associated with purpura fulminans: a case report / Achados histológicos renais em paciente com injúria renal aguda associada à purpura fulminans: relato de caso

ABSTRACT Introduction: Purpura fulminans (PF) is a rapid progressive thrombotic disease in which hemorrhagic infarction of the skin and disseminated intravascular coagulation (DIC) occurs. It can potentially cause acute kidney injury (AKI). However, there is no description in the medical literature of renal histological findings of PF. Case report: A 20-year-old female patient, previously healthy, was admitted to the emergency department (ED) with odynophagia, fever, generalized myalgia and anuria, which evolved with the appearance of purpuric plaques on the face and limbs. She required dialysis on admission. Laboratorial tests showed anemia, leukocytosis, thrombocytopenia, and elevation of lactic dehydrogenase (LDH). The purpuric lesions became bullous with ruptures and then necrotic and erosive, reaching the dermis, subcutaneous tissue and musculature, until bone exposure. There was no improvement with initial antibiotic therapy aimed at the treatment of meningococcemia. Thrombotic microangiopathy (TMA) and PF were then suspected. The patient remained in daily dialysis, requiring plasmapheresis. After sustained improvement of the thrombocytopenia, she underwent renal biopsy, which was not compatible with TMA, characterizing possible PF. A complete recovery of the renal function was achieved and cutaneous sequels were treated with grafts. Conclusion: When thrombotic and hemorrhagic phenomena overlap, obtaining a renal biopsy can be difficult. However, in the presented case, the biopsy allowed the exclusion of AKI caused by TMA, presenting for the first time, histological findings compatible with PF.

RESUMO Introdução: Purpura Fulminans (PF) é uma doença trombótica de rápida progressão, com infarto hemorrágico da pele e coagulação intravascular disseminada (CIVD). É potencialmente causadora de injúria renal aguda (IRA). Porém, não há descrição na literatura médica dos achados histológicos renais causados por PF. Relato de caso: Mulher, 20 anos, previamente hígida, hospitalizada por odinofagia, febre, mialgia generalizada e anúria, evoluiu com aparecimento de placas purpúricas em face e membros. Necessitou de hemodiálise (HD) já na admissão. Exames laboratoriais mostravam anemia, leucocitose, plaquetopenia e elevação de desidrogenase lática. As lesões purpúricas tornaram-se bolhosas com rompimento e progressão para necrose, se aprofundaram, atingindo derme, subcutâneo e musculatura, até a exposição óssea. Não houve melhora com antibioticoterapia inicial voltada para tratamento de meningococemia. Suspeitou-se, então, de microangiopatia trombótica (MAT) e PF. A paciente permaneceu em HD diária e necessitou também de plasmaférese, após melhora sustentada da plaquetopenia, foi submetida à biópsia renal, que não foi compatível com MAT, possivelmente caracterizando PF. Houve recuperação completa da função renal e as sequelas cutâneas foram tratadas com enxerto. Conclusão: Em casos nos quais os fenômenos trombóticos e hemorrágicos se sobrepõem, a obtenção da biópsia renal se torna difícil. Neste caso, a biópsia permitiu excluir IRA causada por MAT e mostrar, pela primeira vez, achados compatíveis com PF.

Purpura fulminans associated with Streptococcus pneumoniae septicemia in an asplenic pediatric patient.

Purpura fulminans is a rapidly progressive syndrome of small-vessel thrombosis and hemorrhagic necrosis of the skin accompanied by disseminated intravascular coagulation. We describe a case of Streptococcus pneumoniae septicemia in an asplenic 5-year-old boy on oral tacrolimus, with a past medical history of multivisceral organ transplantation and subsequent development of purpura fulminans on his chest and distal extremities. The acute infectious form of purpura fulminans is usually caused by gram-negative bacteria. Cases secondary to gram-positive encapsulated bacteria usually occur when individuals are immuno-suppressed or have anatomic or functional asplenia. Our patient had both, which likely increased his susceptibility, and he responded well to antimicrobial therapy in addition to prophylactic coverage in the setting of his immunosuppression. We review the literature for similar cases due to S. pneumoniae in the pediatric population and discuss the etiology and treatment of purpura fulminans.
