[Isolation of three species of Nocardia in a patient receiving long-term corticosteroid therapy].

INTRODUCTION: Nocardia are saprophyte bacteria of the environment responsible for systemic infections in immunodepressed patients, due essentially to long-term corticosteroids. OBSERVATION: A patient having received corticosteroids for sarcoidoses for a year was hospitalised because of disseminated granulomatosis (neurological, respiratory, abdominal and cutaneous). Culture of various bacteriological samples isolated three species of Nocardia: N. otitidiscaviarum in uretheral pus and pus from the right gland, N. nova and N. asteroides in respiratory samples (protected distal sampling and broncho-alveolar washing). COMMENTS: Other than the mixed Nocardia infections described habitually, infections with two different species of Nocardia have recently been reported. Our case report is the first to have isolated three concomitant species of Nocardia.

[Pneumopathy caused by minocycline].

BACKGROUND: Minocycline has been identified as a pathogenic agent in drug-induced pneumonia. We report a new case. CASE REPORT: A 38-year-old female asthmatic patient was given minocycline (100 mg/j) for facial acne. She was allergic to penicillin. Other treatments were theophylline, salbutamol and inhaled budesonide. Severe bilateral hypoxemia pneumonia developed with high eosinophil blood counts within a few days of treatment onset. The lung disease regressed with minocycline withdrawal. DISCUSSION: This case is exceptional because the minocycline-induced lung disease continued to progress despite high-dose corticosteroids in this asthmatic patient.

Bronchial Kaposi's sarcoma after single lung transplantation.

Kaposi's sarcoma (KS) has been reported in 6% of malignancies of solid organ transplant recipients. Most of the observations have been in recipients of renal allografts but, so far, KS has not been described in lung transplantation. We report a case of bronchial KS occurring in a black patient 6 months after single lung-transplantation. Skin lesions were absent and, interestingly, KS lesions were observed solely in the trachea and the native lung. Following reduction of the immunosuppressive regimen a complete remission was obtained 1 year later. Up to the present time, this clinical remission is very encouraging, but close surveillance remains necessary to detect rejection episodes or the reappearance of KS following manipulation of the immunosuppressive therapy.

[Lung volume reduction surgery in emphysema].

Lung volume reduction surgery in emphysema has, as an objective, the reduction of dyspnoea and an increase in the exercise tolerance in patients with respiratory insufficiency suffering from diffuse emphysema. In principle the resection of the most diseased areas of emphysema leads to improvement in the mechanical properties of the emphysematous lung and correct pulmonary hyperinflation. The respiratory function benefits both objective and subjective, produced by surgery are real but transitory and inconstant depending in particular on the evolutionary profile of the emphysematous disease. The indications should be further refined and an objective comparison of different surgical techniques has not been achieved. The impact on the quality of life for these patients is unknown.

[Selection criteria of candidates for lung transplantation].

Amongst the elements which contributed to the success of the early lung transplants at the beginning of the 1980's we feel that the careful selection of candidates probably played a predominant role. If some of the selection criteria initially described remain somewhat intangible, others have either been eased or have been invalidated. The experience acquired over the last 15 years has enabled to precise the optimal moment to include patients on the waiting list and to refine the choice for the type of surgical procedure according to the underlying disease. This article aims to review the different selection criteria for candidates for transplantation and stresses those which have recently undergone change.

[Pulmonary emphysema: surgical indications].

Surgery for pulmonary emphysema, with the exception of lung transplantation, is limited at present to resection of the emphysematous areas. The resection of a unique bulla within an otherwise healthy parenchyma can be indicated in case of complications but rarely in asymptomatic patients. When the bullae are large (i.e. volume greater than one-third of the hemithorax) in a patient suffering from diffuse emphysema, bullectomy is the ideal indication. Mortality varies from 0 to 10%, essentially due to infection or acute respiratory failure. In most patients, the subjective improvement in terms of dyspnea and the objective improvement as measured by spirometry remains significative up to 5 years after surgery. Inversely, surgical resection is classically considered to be contraindicated in patients with small poorly-limited bullae. Recent data would however question this idea since subjective and objective improvement after reduction of the lung volume is still present 1 year after surgery in most patients, even those with severe obstruction. The mechanism is probably related to increased elastic recoil. Even if only temporary improvement can be achieved for a few years, the persisting course of emphysema would suggest that volume reduction should always be entertained as an alternative before lung transplantation.

Lung volume reduction in patients with severe diffuse emphysema. A retrospective study.

BACKGROUND: For most authors, surgery of emphysema is restricted to resection of large bullae, whereas resection of small bullae or lung volume reduction is generally considered to have poor results. STUDY OBJECTIVE: To report our experience of lung volume reduction in patients with severe emphysema without large bullae. PATIENTS: Thirteen patients were operated on from 1982 to 1992. Before surgery, they all had severe diffuse emphysema with a dyspnea grade 4 or 5 and mean FEV1 values of 18 +/- 5% of predicted. Seven patients had a PaCO2 greater than 42 mm Hg. On radiologic evaluation, they had either small bullae or, most often, areas of destroyed lung. INTERVENTION: The surgical procedure was unilateral in 11 patients and bilateral in 2. MEASUREMENTS AND RESULTS: Postoperative assessment included dyspnea grading, FEV1 measurements, and blood gas analysis followed at 6- to 12-month intervals. There was no perioperative mortality and the morbidity was limited. At 6, 12, 18, 24, and 36 months postoperatively, a symptomatic improvement was observed in 92%, 85%, 54%, 31%, and 31% of the patients, respectively, with FEV1 increasing by at least 20% in 92%, 46%, 46%, 31%, and 24% of the patients, respectively. CONCLUSION: Our data show that lung volume reduction may result in symptomatic and spirometric improvement in patients with severe emphysema without large bullae.

[Treatment of severe acute asthma].

Severe acute asthma remains associated with significant mortality. Medical treatment of acute severe episodes includes oxygentherapy, inhaled or intravenous beta-2-agonists, and high doses of systemic corticosteroids. The benefit of additional treatment with other agents such as nebulized ipratropium bromide, epinephrine and intravenous aminophylline is still not well defined. Mechanical ventilation, which remains necessary in case of life-threatening acute respiratory failure, addresses specific problems: PaCO2 may be allowed to remain elevated and ventilator settings should be chosen that avoid barotrauma under appropriate sedation. The use of inhalation anesthesics, helium or even extracorporeal life support necessitates further study to determine the optimal therapeutic strategy in those particular situations.

[Asthma and its treatment during pregnancy].

Asthma occurs in 0.4 to 4.0% of pregnant women and is considered to be the most frequent respiratory disease during pregnancy. Physiological modifications during pregnancy, including hyperventilation due to increased progesterone levels and lower residual volume and functional capacity resulting from increased uterine volume can interfere with the asthmatic disease and require adapted management. Results of studies evaluating the interaction between asthma and pregnancy provide a wide variety of results. For some authors, manifestations of asthma may worsen during pregnancy requiring reinforced medical treatment in as many as 42% of the patients. For others bronchial hyperreactivity is significantly diminished during pregnancy. These findings should be examined in light of several individual factors including the spontaneous clinical course of asthma itself and more rigorous control during pregnancy. It is thus very difficult to predict the effect of pregnancy on clinical manifestations of asthma in any given patient or from one pregnancy to another. Certain authors have observed a correlation between IgE levels and the gravity of asthma in pregnant women: normally IgE levels tend to decline during pregnancy but may remain unchanged or increase if asthma manifestations worsen. Therapeutic options remain unchanged during pregnancy although only drugs proven safe for the fetus may be used. If carefully managed, pregnancy in the asthmatic patient usually reaches term with no major problem.

[Single-lung transplant in chronic obstructive disease].

The feasibility and the good immediate acceptability of unilateral lung transplants in the patients with obstructive respiratory problems have recently been demonstrated and since the initial reports, some hundreds of lung transplants have been performed in various parts of the world for this indication. Nevertheless, few results of respiratory function are currently available in the medium term. We report these in a series of 20 patients with severe obstruction who were given single lung transplants. The actual probability of survival for 1 and 2 years was 75 and 70% respectively with 4 peri-operative deaths and 2 later deaths. In the 16 survivors of more than 6 months, in relation to the pre-operative values, a significant improvement was observed 3 months after the graft in the FEV1 which rose from 17 +/- 6 to 53 +/- 13% of the predicted values. The PaO2 rose from 52 +/- 10 to 81 +/- 3 mmHg. The distance covered on the six minute walking test went from 99 +/- 84 m before the graft to 587 +/- 147 m 6 months after the operation. In addition to the improved distance, the lung function was stable in a group of patients as the months went by, although there was a fall in the respiratory function in others with the appearance of the syndrome of bronchiolitis obliterans or in 2 patients with bronchial complications. The four patients with severe deterioration in the graft function were re-transplanted with a good clinical result in three of them, the fourth dying in the immediate post-operative period. We conclude that single lung transplant represents an effective treatment both in the short and medium term in patients with chronic airflow obstruction.
