Enterite mesentérica como complicação rara do lúpus eritematoso sistêmico / Mesenteric enteritis as a rare complication of systemic lupus erythematosus

A dor abdominal no paciente com lúpus eritematoso sistêmico tem amplo espectro clínico, variando desde condições inespecí- ficas, como diarreia e vômitos, até eventos de importante morbi- mortalidade, como o abdome agudo inflamatório e/ou perfura- tivo. A seguir, descreve-se um caso de paciente do sexo feminino, de 23 anos, internada por dor abdominal associada a vômitos e à diarreia crônica e progressiva. Foi diagnosticada com lúpus eritematoso sistêmico há 2 anos. Durante a internação, evoluiu com quadro de abdome agudo, e foi realizada tomografia compu- tadorizada de abdome, revelando importante edema de parede intestinal difuso. Isso, somado a alterações clínico-laboratoriais, permitiu o diagnóstico de enterite lúpica. Foi realizado tratamen- to conservador, com corticoterapia e terapia de suporte com correção de distúrbios eletrolíticos severos, sendo iniciado ciclo- fosfamida, com resolução dos sintomas gastrintestinais.

Abdominal pain in patients with systemic lupus erythematosus has a broad clinical spectrum, ranging from nonspecific symp- toms, such as diarrhea and vomiting, to events of significant morbidity and mortality, such as acute inflammatory and/or per- forating abdomen. This article describes a case of a 23-year-old female patient hospitalized for abdominal pain, associated with vomiting and progressive chronic diarrhea. She was diagnosed with systemic lupus erythematosus 2 years ago. During hospita- lization, the patient progressed with acute abdomen, and an ab- dominal computed tomography scan was performed, revealing major diffuse intestinal wall edema. This, added to clinical and laboratories alterations, allowed the diagnosis of lupus enteritis. A conservative treatment with corticotherapy and supportive therapy with correction of severe electrolyte disturbances were initiated, as well as the prescription of cyclophosphamide, with resolution of gastrointestinal symptoms.

Catheter-related infection due to Papiliotrema laurentii in an oncologic patient: Case report and systematic review

ABSTRACT Background: Papiliotrema laurentii is one of several non-neoformans cryptococci that have rarely been associated with human infection, since it was previously considered saprophyte and thought to be non-pathogenic to humans. Nevertheless, increasing number of reports of human infection have emerged in recent years, mostly in oncologic patients. Aim: To report a case of a female patient with pyloric obstructive cancer with a catheter-related Papiliotrema laurentii blood stream infection and systematically review the available evidence on P. laurentii infection in humans. Methods: Retrieval of studies was based on Medical Subject Headings and Health Sciences Descriptors, which were combined using Boolean operators. Searches were run on the electronic databases Scopus, Web of Science, MEDLINE (PubMed), BIREME (Biblioteca Regional de Medicina), LILACS (Latin American and Caribbean Health Sciences Literature), Cochrane Library for Systematic Reviews and Opengray.eu. There was no language or date of publication restrictions. The reference lists of the studies retrieved were searched manually. Results: The search strategy retrieved 1703 references. In the final analysis, 31 references were included, with the description of 35 cases. Every patient but one had a previous co-morbidity - 48.4 % of patients had a neoplasm. Amphotericin B was the most used treatment and only a single case of resistance to it was reported. Most patients were cured of the infection. Conclusion: P. laurentii infection in humans is usually associated to neoplasia and multiple co-morbidities, and amphotericin B seems to be a reliable agent for treatment.

Hemangioma esplênico no adulto associado à síndrome de Kasabach-Merritt / Kasabach-Merritt Syndrome-associated adult splenic hemangioma

O hemangioma esplênico, tumor benigno mais frequente do baço, porém, por vezes de difícil diagnóstico, pode integrar a síndrome de Kasabach-Merritt, afecção rara e potencialmente fatal, descrita como associação entre hemangioma, trombocitopenia e coagulopatia de consumo. Apresentamos um caso de paciente de 73 anos em acompanhamento com a hematologia por trombocitopenia crônica a princípio idiopática, que evoluiu com dor abdominal, anemia e derrame pleural. Foi realizada tomografia computadorizada de abdome, que evidenciou massa esplênica sólida heterogênea. A paciente foi submetida a esplenectomia total videolaparoscópica e evoluiu com melhora da dor abdominal e normalização da série plaquetária, sem recorrência do derrame pleural após o procedimento. A raridade e a complexidade do caso, somadas à dificuldade diagnóstica e à abordagem terapêutica, foram fatores que corroboraram para a apresentação desse caso. (AU)

Splenic hemangioma, the most common, but sometimes hard to diagnose, benign tumor of the spleen may integrate Kasabach- Merritt syndrome, a rare and potentially fatal condition described as an association ofhemangioma, thrombocytopenia and consumption coagulopathy. We present a case of a 73-year-old female patient being monitoring, with Hematology due to chronic idiopathic thrombocytopenia who progressed with abdominal pain, anemia and pleural effusion; a computed tomography scan of the abdomen was performed, showing a heterogeneous solid splenic mass. The patient underwent total videolaparoscopic splenectomy and progressed with improvement of abdominal pain and normalization of the platelet series, with no recurrence of pleural effusion after the procedure. The rarity and complexity of the case added to the diagnostic difficulty and therapeutic approach were factors that corroborated for the presentation of this case. (AU)

Evaluación de susceptibilidad y respuesta al tratamiento con piperacilina/tazobactam en pacientes con infecciones por Escherichia coli productoras de β -lactamasas de espectro extendido (BLEE) CTX-M / Evaluation of susceptibility and response to therapy with piperacillin-tazobactam in patients with infections caused by Escherichia coli with extended-spectrum β -lactamase (ESBL) CTX-M

Resumen Introducción: En las infecciones por enterobacterias productoras de β-lactamasas de espectro extendido (BLEE), los β-lactámicos preferidos para tratamiento son los carbapenémicos. Sin embargo, estudios clínicos muestran eficacia de piperacilina/tazobactam en ciertas infecciones por Escherichia coli productoras de BLEE. Objetivo: Determinar la cura clínica y microbiológica con piperacilina/tazobactam en pacientes con infecciones por E. coli productoras de BLEE, tipo CTX-M. Materiales/Métodos: Estudio descriptivo, retrospectivo, con adultos internados en un hospital universitario. Incluimos infecciones del tracto urinario (ITU), intra-abdominales (IIA) e infecciones de tejidos blandos (ITB). Resultados: Estudiamos 40 pacientes, donde 65% correspondían a ITU, 25% IIA y 10 % ITB. La cura clínica global se logró en 89,4%, con mejores resultados en las ITU (100%), seguidas de ITB (80%) e IIA (70%). El 85% de las cepas tenía concentraciones inhibitorias mínimas (CIM) ≤ 8 μg/mL y 70% con CIM ≤ 4 μg/mL. La tasa de fracaso fue mayor en las infecciones con inóculos altos intraabdominales. La BLEE del tipo CTX-M-15 se encontró en 62,5%. Conclusiones: Piperacilina/tazobactam logró cura clínica y microbiológica, en pacientes con infecciones por E. coli productoras de BLEE susceptibles, especialmente en ITU e IPB y en menor medida en IIA.

Background: Carbapenems are the preferred β-lactamics for treatment for infections caused by enterobacteria producing extended-spectrum β-lactamases (ESBL); however, clinical studies show effectiveness of piperacillin/tazobactam in certain infections by Escherichia coli ESBL producers. Aim: To determine the clinical and micro-biological cure with piperacillin/tazobactam in patients with infections caused by E. coli ESBL producers, CTXM type. Methods: Retrospective descriptive study with adults hospitalized in a university hospital. We included urinary tract infections (UTI), intra-abdominal infections (IAI), soft tissue infections (STI) and/or bacteremia. Results: We studied 40 patients, where 65% corresponded to UTI, 25% to IAI and 10% were STI. The overall clinical cure was achieved in 89.4%, with the best results in the ITU (100%), followed by STI (80%) and 70% in IAI. The 85% of the strains had minimum inhibitory concentrations (MIC) ≤8 μg/ml and 70% with MIC ≤4 μg/mL, however the rate of failure were high in intra-abdominal infections with high inocula or not controlled; CTX-M-15 was found in the 62.5%. Conclusions: Piperacillin/tazobactam was efficient to obtain clinical and microbiological cure in patients with infections caused by ESBL producers but susceptible E. coli, especially in UTI and STI and to a lesser extent in IAI.
