Chronic obstructive pulmonary disease (COPD) is an under recognized complication of HIV infection. It is estimated that up to 25% of HIV infected people may have COPD. HIV is associated with COPD as a result of a complex interplay of multiple factors such as pulmonary inflammation, recurrent pulmonary infections especially tuberculosis (TB), increased cigarette smoking, socio-economic status, childhood respiratory illnesses and industrial and environmental exposures; each of which are risk factors for COPD in their own right. ⋯ Prevention and control of HIV infection must be part of the multiple interventions to reduce the global burden of COPD. A multidisciplinary approach, including behavioural science is required to address this challenge. It presents research opportunities that should be driven by the pulmonology community.

Opportunistic chronic obstructive pulmonary disease (COPD) case finding approaches for high-risk individuals with or without symptoms is a feasible option for disease identification. PUMA is an opportunistic case finding study conducted in primary care setting of Argentina, Colombia, Venezuela and Uruguay. The objectives were to measure COPD prevalence in an at-risk population visiting primary care for any reason, to assess the yield of this opportunistic approach and the accuracy of a score developed to detect COPD. ⋯ This simple seven-item score is an accurate screening tool to select subjects for spirometry in primary care.

The aim of endoscopic valve therapy in patients with emphysema is complete lobar atelectasis of the most emphysematous lobe. However, even after the radiological advent of atelectasis, great variability in clinical outcomes can be observed. ⋯ Low attenuation volume of the target lobe to LAV of the target lung and baseline clinical measures seem to significantly predict clinical outcomes in patients with complete lobar atelectasis following valve treatment.

Review Meta Analysis
Statins for the prevention and treatment of acute lung injury and acute respiratory distress syndrome: a systematic review and meta-analysis.
The purpose of this meta-analysis was to assess whether statins could reduce the morbidity of acute lung injury and acute respiratory distress syndrome (ALI/ARDS) in high-risk patients and improve the clinical outcomes of patients with ALI/ARDS. Studies were obtained from PubMed, Medline, Embase and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) and cohort studies, which reported morbidity, mortality, ventilator-free days, length of stay in intensive care unit and hospital or oxygenation index, were included in our meta-analysis. ⋯ Moreover, no significant difference was observed in ventilator-free days, length of stay in intensive care unit as well as hospital and oxygenation index. This meta-analysis suggests that statins neither provide benefit for lowering the morbidity of ALI/ARDS in high-risk patients nor improve the clinical outcomes of ALI/ARDS patients. Hence, it may not be appropriate to advocate statin use for the prevention and treatment of ALI/ARDS.

Co-morbidities in idiopathic pulmonary fibrosis are common. These co-morbidities include obstructive sleep apnoea, gastro-oesophageal reflux disease, pulmonary hypertension and depression. The presence of co-morbidities among patients with idiopathic pulmonary fibrosis contributes to worse quality of life, morbidity and mortality. ⋯ The impact of co-morbidities on this patient population is becoming more apparent. Their relevance will only increase as significant effort is being made to develop novel therapeutics that will alter the disease trajectory of patients with idiopathic pulmonary fibrosis. The purpose of this review is to focus on the epidemiology, pathophysiology, diagnosis and management of select co-morbidities, including obstructive sleep apnoea, gastro-oesophageal reflux disease, pulmonary hypertension and depression, in idiopathic pulmonary fibrosis.
