Introduction: Treatment with biological therapies increases the incidence of tuberculous disease. The introduction of systematic screening for latent tuberculosis infection in patients who are to receive these therapies has reduced this risk. In 2016, the consensus document on the prevention and treatment of tuberculosis in patients who are candidates for biological treatment was published in Spain. The main objective of this study was to evaluate adherence to these guidelines., Methods: Multicenter, descriptive, observational study via an anonymous online survey sent to medical societies involved in biologics., Results: We received 747 responses. Most respondents performed screening at the right time in the right patients (93.7%). Only 36.6% of respondents requested the appropriate diagnostic test, while 56.3% correctly recommended chemoprophylaxis. Up to 96% were familiar with the recommended chemoprophylaxis regimens, while only 63.9% initiated them at the right time. The specialist area that participated most and screened most patients for latent tuberculosis infection was rheumatology (54%). In most cases, pulmonologists were involved in an advisory capacity., Conclusions: This study shows poor overall adherence to recommendations, with only 56% of respondents reporting appropriate compliance. The incidence of tuberculous disease in patients who are to receive biological therapies could be reduced further by emphasizing the importance of the right diagnostic test and use of the diagnostic algorithm for latent tuberculosis infection., (Copyright © 2018 SEPAR.

Spontaneous pneumothorax is a relatively frequent complication of human immunodeficiency virus (HIV) infection. Seven hundred sixty-five HIV-infected inpatients were treated at Marques de Valdecilla University Hospital between 1990 and 1996. Spontaneous pneumothorax developed in 9 patients. Pneumocystis carinii pneumonia was diagnosed in 6 patients (66%), either before or simultaneous to the appearance of pneumothorax. Pneumothorax was related to active or old tuberculosis infection in 3 patients (33%). Prophylactic therapy with nebulized pentamidine was used in 55% of the patients. Successful initial control of pneumothorax was achieved with simple drains in 58% of the episodes, although the recurrence rate was 71%. Pleurodesis with talcum with a chest tube was used successfully in 3 patients, in 2 because of sings of persistent air leakage uncorrected by simple drainage. Pleurodesis initially failed but later controlled pneumothorax the second time it was used. The mortality rate in this series was 66%, with a mean survival time of 55.6 days. We conclude that spontaneous pneumothorax is associated with poor prognosis in HIV infected patients. Prior or concurrent P. carinni pneumonia or tuberculosis were the etiologic factors identified in our patients. A simple pleural drain was associated with a high rate of recurrence, such that pleurodesis seems warranted in all patients.
