Proteomic profiling of bronchoalveolar lavage fluid uncovers protein clusters linked to survival in idiopathic forms of interstitial lung disease.

Background: Idiopathic interstitial pneumonias (IIPs), such as idiopathic pulmonary fibrosis and interstitial pneumonia with autoimmune features, present diagnostic and therapeutic challenges due to their heterogeneous nature. This study aimed to identify intrinsic molecular signatures within the lung microenvironment of these IIPs through proteomic analysis of bronchoalveolar lavage fluid (BALF).

Methods: Patients with IIP (n=23) underwent comprehensive clinical evaluation including pre-treatment bronchoscopy and were compared with controls without lung disease (n=5).

Neutrophil extracellular traps linked to idiopathic pulmonary fibrosis severity and survival.

Background: Idiopathic pulmonary fibrosis (IPF) leads to progressive loss of lung function and mortality. Understanding mechanisms and markers of lung injury in IPF is paramount to improving outcomes for these patients. Despite the lack of systemic involvement in IPF, many analyses focus on identifying prognostic markers.

21st century natural product research and drug development and traditional medicines.

Natural products and related structures are essential sources of new pharmaceuticals, because of the immense variety of functionally relevant secondary metabolites of microbial and plant species. Furthermore, the development of powerful analytical tools based upon genomics, proteomics, metabolomics, bioinformatics and other 21st century technologies are greatly expediting identification and characterization of these natural products. Here we discuss the synergistic and reciprocal benefits of linking these 'omics technologies with robust ethnobotanical and ethnomedical studies of traditional medicines, to provide critically needed improved medicines and treatments that are inexpensive, accessible, safe and reliable.

Dose separation does not overcome the pharmacokinetic interaction between fosamprenavir and lopinavir/ritonavir.

Previous investigations have shown a significant negative two-way drug interaction between fosamprenavir (FPV) and lopinavir/ritonavir (LPV/RTV) in both human immunodeficiency virus (HIV)-infected patients and seronegative volunteers. This randomized, nonblinded, three-way crossover study of HIV-seronegative adult volunteers investigated dose separation and increased doses of RTV as a means to overcome the interaction between FPV and LPV/RTV. Eleven HIV-seronegative volunteers were given FPV plus LPV/RTV at 700 mg plus 400/100 mg every 12 hours (q12h) simultaneously for 10 days and then randomized to receive each of three 7-day treatments in one of six possible sequences, as follows: FPV plus LPV/RTV at 700 mg plus 400 mg/100 mg q12h simultaneously, FPV/RTV at 700 mg/100 mg q12h plus LPV/RTV at 400 mg/100 mg q12h, with doses separated by 4 h, and FPV/RTV at 1,400 mg/200 mg in the morning plus LPV/RTV at 800 mg/200 mg in the evening.
