In patients with idiopathic pulmonary fibrosis, nintedanib reduced the decline in FVC, which is consistent with a slowing of disease progression; nintedanib was frequently associated with diarrhea, which led to discontinuation of the study medication in less than 5% of patients. (Funded by Boehringer Ingelheim; INPULSIS-1 and INPULSIS-2 ClinicalTrials.gov numbers, NCT01335464 and NCT01335477.).

The guideline panel provided recommendations related to the diagnosis of IPF.

The panel formulated and provided the rationale for recommendations in favor of or against treatment interventions for idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a fatal disorder without an effective therapy to date. In a double-blind, randomized, placebo-controlled trial, 107 patients were prospectively evaluated for efficacy of a novel compound, pirfenidone. The difference in the change in the lowest oxygen saturation by pulse oximetry (SpO2) during a 6-minute exercise test, the primary endpoint, from baseline to 6 months was not significant between the two groups (p = 0.0722). In a prespecified subset of patients who maintained a SpO2 greater than 80% during a 6-minute exercise test at baseline, the lowest SpO2 improved during a 6-minute exercise test in the pirfenidone group at 6 and 9 months (p = 0.0069 and 0.0305, respectively). Positive treatment effect was demonstrated in secondary endpoints: (1) change in VC measurements at 9 months (p = 0.0366) and (2) episodes of acute exacerbation of IPF occurring exclusively in the placebo group during the 9 months (p = 0.0031). Significant adverse events were associated with pirfenidone; however, adherence to treatment regimen was similar between pirfenidone and placebo groups. In conclusion, treatment with pirfenidone improved VC and prevented acute exacerbation of IPF during the 9 months of follow-up. Future long-term studies are needed to clarify the overall safety and efficacy of pirfenidone in IPF.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease without proven effective therapy.A multicentre, double-blind, placebo-controlled, randomised phase III clinical trial was conducted in Japanese patients with well-defined IPF to determine the efficacy and safety of pirfenidone, a novel antifibrotic oral agent, over 52 weeks. Of 275 patients randomised (high-dose, 1,800 mg?day ; or placebo groups in the ratio 2:1:2), 267 patients were evaluated for the efficacy of pirfenidone. Prior to unblinding, the primary end-point was revised; the change in vital capacity (VC) was assessed at week 52. Secondary end-points included the progression-free survival (PFS) time.Significant differences were observed in VC decline (primary end-point) between the placebo group (-0.16 L) and the high-dose group (-0.09 L) (p50.0416); differences between the two groups (p50.0280) were also observed in the PFS (the secondary end-point). Although photosensitivity, a well-established side-effect of pirfenidone, was the major adverse event in this study, it was mild in severity in most of the patients.Pirfenidone was relatively well tolerated in patients with IPF. Treatment with pirfenidone may decrease the rate of decline in VC and may increase the PFS time over 52 weeks. Additional studies are needed to confirm these findings.

The present study was designed to identify recent clinical phenotypes using the National Epidemiological Survey and to compare findings with those of previous surveys in Japan.Pathologically confirmed sarcoidosis cases newly diagnosed in 2004 were eligible for the present study. Disease parameters were recorded and compared.A total of 1,027 patients were enrolled from a cluster encompassing 79.4% of the entire Japanese population. The study participants consisted of 364 males and 663 females, providing an average incidence rate of 1.01 per 100,000 inhabitants (0.73 for males and 1.28 for females). The age-specific incidence rate displayed a biphasic pattern in the whole patient population and in the females. The male incidence rates peaked in the 20-34-yr-old group. A second peak for 50-60-yr-old females showed a higher incidence than the first younger peak. Patients with abnormalities in eyes, skin and cardiac laboratory findings accounted for 54.8, 35.4 and 23.0% of cases, respectively. The female/male incidence ratio was increased, and the frequency of eye and skin involvement and cardiac abnormality was higher than in previous surveys conducted in Japan.In conclusion, the data obtained in the present study differ from those of other countries and showed changes in sarcoidosis clinical phenotypes compared with previous studies in Japan.
