Cytokine levels in pleural fluid as markers of acute rejection after lung transplantation

Citocinas no líquido pleural após transplante pulmonar como marcadores de rejeição aguda

Abstract PDF PT PDF EN Portuguese Text

Our objective was to determine the levels of lactate dehydrogenase, IL-6, IL-8, and VEGF, as well as the total and differential cell counts, in the pleural fluid of lung transplant recipients, correlating those levels with the occurrence and severity of rejection. We analyzed pleural fluid samples collected from 18 patients at various time points (up to postoperative day 4). The levels of IL-6, IL-8, and VEGF tended to elevate in parallel with increases in the severity of rejection. Our results suggest that these levels are markers of acute graft rejection in lung transplant recipients.

Lung transplantation presents a wide range of challenges for multidisciplinary teams that manage the care of the recipients. Transplant teams should perform a thorough evaluation of transplant candidates, in order to ensure the best possible post-transplant outcomes. That is especially true for the psychologist, because psychological issues can arise at any point during the perioperative period. The objective of our study was to evaluate the psychological causes of contraindication to waiting list inclusion in a referral program for lung transplantation. We retrospectively analyzed data on psychological issues presented by lung transplant candidates, in order to understand these matters in our population and to reflect upon ways to improve the selection process.

Alveolar hemorrhage associated with lupus nephritis

Hemorragia alveolar associada a nefrite lúpica

Ricardo Henrique de Oliveira Braga Teixeira, Marcel Hiratsuka, Flávia Calderini Rosa, Rogério Souza, Carlos Roberto Ribeiro de Carvalho

J Bras Pneumol.2003;29(6):401-404

Abstract PDF PT

Alveolar hemorrhage leading to respiratory failure is uncommon. Various etiologies have been reported, including systemic lupus erythematosus, which generally presents as pulmonary-renal syndrome. It is believed that the pathogenesis of microangiopathy is related to deposits of immune complexes that lead to activation of cellular apoptosis. The authors report two cases of alveolar hemorrhage and respiratory failure, both requiring mechanical ventilation. The two cases had opposite outcomes after pharmacological therapy. The presence of anti-glomerular basement membrane antibodies in one of the cases demonstrates the multiplicity of physiopathological mechanisms that may be involved. This multiplicity of mechanisms provides a possible explanation for the heterogeneous responses to the available treatments.

Lung hyperinflation after single lung transplantation to treat emphysema

Hiperinsuflação pulmonar após transplante unilateral por enfisema

Marcos Naoyuki Samano, Jader Joel Machado Junqueira, Ricardo Henrique de Oliveira Braga Teixeira, Marlova Luzzi Caramori, Paulo Manuel Pêgo-Fernandes, Fabio Biscegli Jatene

J Bras Pneumol.2010;36(2):265-269

Abstract PDF PT PDF EN Portuguese Text

Despite preventive measures, lung hyperinflation is a relatively common complication following single lung transplantation to treat pulmonary emphysema. The progressive compression of the graft can cause mediastinal shift and respiratory failure. In addition to therapeutic strategies such as independent ventilation, the treatment consists of the reduction of native lung volume by means of lobectomy or lung volume reduction surgery. We report two cases of native lung hyperinflation after single lung transplantation. Both cases were treated by means of lobectomy or lung volume reduction surgery.

Treatment of bronchial stenosis after lung transplantation using a self-expanding metal endobronchial stent

Utilização de endoprótese metálica no tratamento de estenose brônquica após transplante pulmonar

Abstract PDF PT PDF EN Portuguese Text

Although the incidence of bronchial anastomosis as a complication of lung transplantation has decreased in recent years, it remains a significant cause of morbidity and mortality in these patients. Treatment options include balloon dilatation, laser photocoagulation, placement of a stent (silicone or metal), and performing a second operation. We report the case of a patient who presented bronchial stenosis after left lung transplantation and was treated with a self-expanding metal alloy (nitinol) stent (UltraflexÒ). Despite the fact that this was the first case of stenosis treated in this fashion in Brazil, the positive clinical response, in agreement with results reported in the literature, indicates that this treatment is a viable alternative in such cases.
