Hepatic transplant during SARS-CoV-2 (COVID-19) pandemic. A literature review.

Antecedentes: En diciembre de 2019 se identificó en la ciudad de Wuhan, China, un nuevo beta coronavirus, el SARS-CoV-2, como agente causal de neumonía grave, conocida como COVID-19, lo cual ha provocado medidas estrictas de aislamiento, cierre de programas de trasplante hepático y la necesidad de modificar los protocolos de tratamiento.

Objetivo: Documentar la información publicada sobre el impacto de la COVID-19 en la población con antecedente de trasplante hepático y establecer un protocolo de tratamiento.

MÉtodo: Se buscaron en PubMed los términos MeSH "SARS-CoV-2", "COVID-19", "trasplante hepático" y "tratamiento".

COVID-19-Associated Pulmonary Aspergillosis, March-August 2020.

Pneumonia caused by severe acute respiratory syndrome coronavirus 2 emerged in China at the end of 2019. Because of the severe immunomodulation and lymphocyte depletion caused by this virus and the subsequent administration of drugs directed at the immune system, we anticipated that patients might experience fungal superinfection. We collected data from 186 patients who had coronavirus disease-associated pulmonary aspergillosis (CAPA) worldwide during March-August 2020.

De vuelta a la clínica. Métodos I. Diseños de investigación. Mayor calidad de información, mayor certeza a la respuesta.

Research designs refer to the way information is obtained and are limited by ethical, economic and temporal viability. Research designs are standardized strategies to reduce biases, which in the architectural model of research are identified in the baseline state, the maneuver and the outcome; hence, there are no specific designs for each question. The design with the lowest probability of bias is the clinical trial, followed by cohort and case-control studies and, finally, by cross-sectional surveys.

Candida norvegensis fungemia in a liver transplant recipient.

Background: The incidence of candidemia due to non-Candida albicans Candida species has been progressively increasing in recent years. The use of fluconazole as antifungal prophylaxis has been described as a risk factor for the development of infections by fluconazole resistant Candida strains. We report a case of Candida norvegensis bloodstream infection in a liver transplant recipient.

Incidence and outcome of early Candida peritonitis after liver and pancreas transplantation.

Candida peritonitis is a potentially life-threatening infection after abdominal transplantation, although there is scant information regarding its incidence and outcome. We analysed the incidence rate and outcome of Candida peritonitis in 717 liver or pancreas transplant recipients. Five cases of Candida peritonitis were diagnosed, representing the second most frequent cause of invasive fungal infection in the cohort.

Decreased serum linezolid concentrations in two patients receiving linezolid and rifampicin due to bone infections.

Methicillin-resistant Staphylococcus is a common cause of orthopaedic implant infections. In such cases, rifampicin is the antibiotic of choice, but it should not be administered alone to avoid the selection of resistant mutants. Linezolid has activity against resistant staphylococci and a high oral bioavailability; therefore, it could be a good option for combining with rifampicin.

Toxoplasma gondii primary infection in renal transplant recipients. Two case reports and literature review.

Toxoplasmosis after solid organ transplantation is a complication associated with high morbidity and mortality. Universal prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX) is effective to prevent post-transplant toxoplasmosis. We report two cases of renal transplant recipients with negative antibodies against Toxoplasma gondii pretransplant who developed toxoplasmosis after TMP-SMX discontinuation.
