Abstract

Background In this retrospective Italian study, which involved all major national interstitial lung diseases centers, we evaluated the effect of pirfenidone on disease progression in patients with IPF.Methods We retrospectively studied 128 patients diagnosed with mild, moderate or severe IPF, and the decline in lung function monitored during the one-year treatment with pirfenidone was compared with the decline measured during the one-year pre-treatment period.Results At baseline (first pirfenidone prescription), the mean percentage forced vital capacity (FVC) was 75% (35-143%) of predicted, and the mean percentage diffuse lung capacity (DLCO) was 47% (17-120%) of predicted. Forty-eight patients (37.5%) had mild disease (GAP index stage I), 64 patients (50%) had moderate IPF (stage II), and 8 patients (6.3%) had severe disease (stage III). In the whole population, pirfenidone attenuated the decline in FVC (p = 0.065), but did not influence the decline in DLCO (p = 0.355) in comparison to the pre-treatment period. Stratification of patients into mild and severe disease groups based on %FVC level at baseline (>75% and ≤75%) revealed that attenuation of decline in FVC (p = 0.002) was more pronounced in second group of patients. Stratification of patients according to GAP index at baseline (stage I vs. II/III) also revealed that attenuation of decline in lung function was more pronounced in patients with more severe disease.Conclusions In this national experience, pirfenidone reduced the rate of annual FVC decline (p = 0.065). Since pirfenidone provided significant treatment benefit for patients with moderate-severe disease, our results suggest that the drug may also be effective in patients with more advanced disease.

  • Systematic reviews and meta-analyses failed to show any therapeutic benefit of systemic corticosteroids in IPF.

    “Systemic corticosteroids have been widely studied in the treatment of IPF with systematic reviews and meta-analyses failing to show any therapeutic benefit [23,52,53].”

    From Emerging pharmacological options in the treatment of idiopathic pulmonary fibrosis (IPF) (2024) · cites this paper as [23]

    The Discussion (p. 8) says corticosteroids have been demonstrated ineffective in IPF, and the References (p. 9) include a systematic review on corticosteroids. The paper does not say that multiple systematic reviews and meta-analyses reached this conclusion; its own study evaluated pirfenidone, not corticosteroids. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
