Methods: An open-label, single-arm, interventional clinical trial in which LAM patients received doxycycline (100 mg/day) for 12 months. Patients underwent full pulmonary function testing, a six-minute walk test, and quality of life assessment, as well as blood and urine sampling for quantification of MMP-2, MMP-9, and VEGF-D levels at baseline, as well as at 6 and 12 months after the initiation of doxycycline. Results: Thirty-one LAM patients received doxycycline for 12 months. Although there was effective blockade of urinary MMP-9 and serum MMP-2 after treatment, there were no significant differences between pre-and post-doxycycline serum levels of MMP-9 and VEGF-D. On the basis of their response to doxycycline (as determined by the variation in FEV1), the patients were divided into two groups: the doxycydine-responder (doxy-R) group (n = 13); and the doxycycline-nonresponder (doxy-NR) group (n = 18). The patients with mild spirometric abnormalities responded better to doxycycline. The most common side effects were mild epigastric pain, nausea, and diarrhea. Conclusions: In patients with LAM, doxycydine treatment results in effective MMP blockade, as well as in improved lung function and quality of life in those with less severe disease. However, these benefits do not seem to be related to the MMP blockade, raising the hypothesis that there is a different mechanism of action.

R.- Pseudocisto pulmonar pós-traumático em jogador de futebol: relato de caso(2013) COSTA, Andre Nathan; GIASSI, Karina de Souza; BACHION, Guilherme Hipolito; APANAVICIUS, Andre; MUSOLINO, Rafael Silva; KAIRALLA, Ronaldo AdibPulmonary pseudocysts are uncommon cavitary lesions that develop in the lung parenchyma as a consequence of blunt thoracic trauma, whose diagnosis is based on an association of clinical history and imaging findings. The present report describes the case of a pulmonary pseudocyst observed in the parenchyma contralateral to the trauma site in a 31-year-old man presenting with hemoptysis after falling during a soccer match.
- A pilot study assessing the effect of bronchodilator on dynamic hyperinflation in LAM(2013) BALDI, Bruno Guedes; ALBUQUERQUE, Andre Luis Pereira de; PIMENTA, Suzana Pinheiro; SALGE, Joao Marcos; KAIRALLA, Ronaldo Adib; CARVALHO, Carlos Roberto RibeiroIntroduction: Positive responses to bronchodilators (BDs) on spirometry can be found in up to 30% of patients with lymphangioleiomyomatosis (LAM). However, no previous studies have investigated the impact of BDs on exercise outcomes, including dynamic hyperinflation (DH). Methods: A randomised, double-blind, placebo-controlled, crossover trial was conducted on 38 patients with LAM, comparing inhaled placebo versus salbutamol. Pulmonary function tests and a cycle endurance test at 75% of the maximal work capacity, with evaluation of DH by serial measurement of inspiratory capacity (IC), which was the primary endpoint, were performed after each intervention. Results: Although salbutamol produced a slight improvement in airway obstruction, compared with placebo, there was no significant variation in resting IC or air trapping. A total of 18% of the patients met the criteria for a positive response to BD. During submaximal exercise, BD did not reduce DH or dyspnoea nor did it improve exercise tolerance in the entire population. In addition, BD produced only slight improvement in FEV1 and air trapping in patients who had DH during incremental cardiopulmonary exercise testing, without the beneficial effects on exercise outcomes. Conclusions: Although salbutamol produced a slight improvement in airway obstruction, it did not lead to a reduction in DH or increase in exercise tolerance in patients with LAM.
