BACKGROUND Kaposi's sarcoma in HIV antibody positive patients may affect the lungs. This study describes the presentation, chest radiographic appearances, and pulmonary function test abnormalities in patients with AIDS who had tracheobronchial Kaposi's sarcoma. METHODS AND RESULTS Twenty nine (8%) of 361 consecutive HIV antibody positive patients(More)
The value of continuous positive airway pressure (CPAP) ventilation via a tight fitting face mask was assessed in eight HIV-1 antibody-positive patients with Pneumocystis carinii pneumonia who were in hypoxaemic respiratory failure. All patients were conscious, able to protect their airway and not hypercapnic. Treatment was effective in seven patients.(More)
We prospectively compared sputum induction with bronchoalveolar lavage (BAL) in HIV positive patients presenting with acute respiratory episodes and also assessed the effects of using an experienced respiratory physiotherapist on the diagnostic yield from induced sputum. One hundred and fifty-one consecutive patients underwent sputum induction, in 96 the(More)
OBJECTIVES To determine serum concentrations of proinflammatory (C reactive protein, complement C3 and C4) and anti-inflammatory (alpha(1) antitrypsin, C1 esterase inhibitor (C1-INH)) acute phase proteins in elite cyclists before and during a three week cycle tour. METHODS Seventeen professional cyclists participating in the Vuelta a Espańa volunteered(More)
BACKGROUND Strenuous exercise is associated with tissue damage. This activates the innate immune system and local inflammation. Interaction between innate and adaptive immunity is essential for maintaining health, suggesting that the adaptive immune system may also be altered by exercise. OBJECTIVES To determine exercise induced changes in the adaptive(More)
OBJECTIVE To examine the effect of downhill running on immunoglobulin responses. METHOD Eleven untrained men performed 2 x 60 minute bouts of downhill running (-13.5% gradient), at a speed eliciting 75% of their vO2peak on a level grade. Two runs were spaced 14 days apart. Serum samples were collected before, after, and every hour for 12 hours and every(More)
1. The hypothesis that respiratory oscillations of arterial blood gas composition influence ventilation has been examined. 2. Phrenic motoneurone output recorded in the C5 root of the left phrenic nerve and the respiratory oscillations of arterial pH in the right common carotid artery were measured in vagotomized anaesthetized dogs which had been paralysed(More)
