Article Abstract
Background: The ability of bronchial amylase level for predicting ventilator associated pneumonia (VAP) has been extensively studied with conflicting results. This meta-analysis aimed to explore the value of bronchial amylase for predicting VAP in intubated adults.
Methods: PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched up to November 2023. The diagnostic odds ratio (DOR), sensitivity, and specificity were calculated. The summary receiver operating characteristic curve was estimated, and the area under the curve (AUROC) was calculated.
Results: Overall, six studies including 769 patients were included in this review, of whom 273 (36%) were developed VAP. The cutoff values of bronchial amylase level were ranged from 8.1 U/L to 4681.5U/L. Heterogeneity between studies was assessed with an overall Q = 1.99, I = 0, and P = 0.185, The pooled sensitivity and specificity for the overall population were 0.78 [95% confidence interval (CI) 0.67-0.86] and 0.75(95% CI 0.56-0.88) respectively. The DOR was 11(95% CI 3.0-40.0). The pooled AUROC was 0.83 (95%CI 0.80-0.86).
Conclusions: The bronchial amylase is a helpful marker for predicting VAP in intubated adults. However, it cannot be recommended as the single definitive test for VAP, but rather it must be interpreted in context with information from careful medical history, physical examination, and when feasible, microbiological assessment.

Legumes in bread baking: A hidden risk for an IgE-mediated inhalant allergy.

New protein-rich flour blends from legumes are increasingly being processed for gluten-free bakery products, which may increase the risk of IgE-mediated sensitization through inhalation exposure. In the described case of a 29-year-old baker, work incapacity occurred due to respiratory complaints following exposure to various gluten-free baking ingredients. Occupation-related sensitization to "chestnut pea flour" (flour from lightly roasted and ground yellow peas) was identified, while the patient showed no IgE sensitization to five other ingredients.

Article Synopsis
- This meta-analysis evaluated the effectiveness of bronchial amylase levels in predicting ventilator-associated pneumonia (VAP) in adults on ventilators, after analyzing data from multiple studies.
- A total of six studies involving 769 patients found that about 36% developed VAP, and the bronchial amylase levels varied widely.
- The findings suggested that while bronchial amylase has a useful role in VAP prediction (with a sensitivity of 78% and specificity of 75%), it should not be the sole determinant for diagnosis, and should be used alongside other clinical assessments.
