1. Targeting Gut-Lung Crosstalk in Acute Respiratory Distress Syndrome: Exploring the Therapeutic Potential of Fecal Microbiota Transplantation.
Narrative/translation review arguing that gut microbiota modulates immune responses relevant to ARDS and that fecal microbiota transplantation (FMT) shows beneficial effects in preclinical ARDS models (reduced inflammation, oxidative stress, and improved oxygenation). The paper highlights the lack of randomized clinical trials and proposes FMT as a candidate for translational research.
Impact: Proposes a novel, translational therapeutic approach (FMT) targeting the gut–lung axis in ARDS and synthesizes preclinical evidence, potentially opening new clinical trial avenues.
Clinical Implications: Not immediately practice-changing but provides a mechanistic rationale to justify early-phase clinical trials of FMT in ARDS/sepsis-related lung injury; suggests monitoring systemic inflammation and oxygenation as endpoints.
Key Findings
- Gut microbiota significantly influences systemic immunity and may exacerbate or ameliorate lung injury via the gut–lung axis.
- Preclinical ARDS models show FMT can reduce inflammation, oxidative stress, and improve oxygenation and lung injury metrics.
- There is a current lack of well-designed randomized clinical trials of FMT in ARDS patients despite promising preclinical data.
Methodological Strengths
- Integrates mechanistic literature linking gut microbiota and systemic inflammation to lung injury.
- Highlights preclinical experimental data across in vivo and in vitro ARDS models.
Limitations
- Narrative review without systematic review methodology or meta-analysis; risk of selection bias in cited studies.
- Preclinical findings may not translate to human ARDS; heterogeneity of ARDS etiologies is not fully addressed.
Future Directions: Initiate carefully designed phase 1/2 randomized trials of FMT in well-characterized ARDS or sepsis-associated acute lung injury cohorts with mechanistic endpoints (inflammatory biomarkers, microbiome shifts, oxygenation indices). Standardize donor selection, FMT delivery route, and safety monitoring.
2. Acute Exacerbation of Interstitial Lung Disease: Early Diagnosis and Treatment.
Comprehensive review summarizing incidence, high mortality, diagnostic criteria (acute worsening within 30 days, new bilateral ground-glass/consolidation on HRCT after excluding cardiac causes) and current treatment options (corticosteroids, antibiotics, immunosuppressants, oxygen/ventilatory support) for AE-ILD; provides practical management algorithms despite limited RCT evidence.
Impact: AE-ILD carries high mortality and diagnostic overlap with ARDS; this review consolidates practical diagnostic criteria and management algorithms that clinicians can apply when ARDS-like acute worsening occurs in ILD patients.
Clinical Implications: Supports early recognition of AE-ILD, systematic exclusion of cardiac/volume overload causes, early use of oxygen/ventilatory support, and considered use of corticosteroids/immunosuppression despite limited RCT data; provides stepwise algorithms for ICU and non-ICU settings.
Key Findings
- AE-ILD has substantial incidence and in-hospital mortality (>50% in IPF), and histologically often resembles diffuse alveolar damage seen in ARDS.
- Diagnostic criteria emphasize acute respiratory worsening within 30 days plus new bilateral ground-glass/consolidation on HRCT after excluding heart failure/fluid overload.
- Pharmacologic therapies (corticosteroids, antibiotics, immunosuppressants) are commonly used, but randomized placebo-controlled trial evidence is scarce; oxygen and ventilatory support remain central.
Methodological Strengths
- Provides updated, clinically oriented synthesis and practical algorithms for diagnosis and management.
- Brings together incidence/mortality data across ILD subtypes and clarifies radiologic/histologic overlap with ARDS.
Limitations
- Review article without high-level randomized evidence to support many therapeutic recommendations.
- Heterogeneity among ILD subtypes and patient comorbidities limits generalizability of algorithmic recommendations.
Future Directions: Well-designed multicenter observational studies and randomized trials targeting AE-ILD therapeutic strategies (steroid dosing, immunosuppression, ventilatory approaches) are needed; biomarker-driven stratification may improve trial design.
3. Chemical Pneumonitis Following Inhalation of Fluoride-Based Waterproofing Agent: A Case Series.
Retrospective case series of seven occupational exposures to fluoride-based waterproofing agent resulting in acute chemical pneumonitis; one patient progressed to ARDS with multi-organ failure within 24 hours. Authors report characteristic CT acute lung injury patterns, elevated fluoride levels in one case, and favorable emphasis on early recognition, oxygenation-index–guided respiratory support, and early high-dose corticosteroids.
Impact: Documents a rapidly progressive, occupationally related toxic lung injury that can cause ARDS within hours and offers practical management recommendations (early steroid use, oxygenation-index guided respiratory support) for a rare but severe exposure.
Clinical Implications: In occupational exposures to fluoride-containing agents, maintain high index of suspicion for rapid deterioration; obtain CT imaging and fluoride assays when indicated; apply stepwise respiratory support based on oxygenation index and consider early high-dose corticosteroids alongside supportive care.
Key Findings
- Seven occupational exposure cases to fluoride-based waterproofing agents produced acute chemical pneumonitis; one patient developed ARDS with multi-organ failure within 24 hours.
- Chest CT showed acute lung injury patterns consistent with rapid toxic pneumonitis; one case had markedly elevated blood and urinary fluoride levels and systemic inflammation.
- All patients received respiratory support and corticosteroids; authors recommend early recognition and oxygenation-index–guided stepwise respiratory management with early high-dose steroids to improve prognosis.
Methodological Strengths
- Clear occupational exposure history for all cases with laboratory confirmation (in at least one case) and chest CT imaging documenting acute lung injury.
- Provides practical, actionable recommendations for early management in a rare but high-risk exposure setting.
Limitations
- Small retrospective case series (n=7) without a control group limits causal inference and generalizability.
- Only one patient had documented elevated fluoride measurements; dosing/exposure quantification across cases is limited.
Future Directions: Prospective occupational surveillance for fluoride-containing agents, standardized exposure measurement, toxicokinetic studies, and protocols for early management including steroid dosing and respiratory support thresholds are required.
