Study Title | Metabolomics panel associated with cystic fibrosis-related diabetes towards biomarker discovery |
Study Summary | Background: The most prevalent comorbidity among cystic fibrosis (CF) patients is cystic fibrosis-related diabetes (CFRD). CFRD has been linked to one of the worse clinical outcomes and higher mortality. Improved clinical results have been related to earlier diagnosis and treatment of CFRD. Therefore, the present study aimed to investigate the metabolome of human serum of patients with CFRD. This might aid in identifying novel biomarkers linked with the pathophysiology of CFRD and its diagnosis. Methods: The liquid chromatography–high-resolution mass spectrometry (LC–HRMS) metabolomics approach was utilized for serum samples from patients with CF (n= 36) and healthy control (n=36). Among the CF group, nine patients were with CFRD and 27 were non-CFRD (nCFRD). Results: A total of 2328 metabolites were significantly altered in CF compared to the healthy control. Among those, 799 significantly dysregulated metabolites were identified between CFRD and nCFRD. Arachidonic acid (AA), ascorbate, and aldarate metabolism were the most common metabolic pathways dysregulated in CF. L-homocysteic acid (L-HCA) levels were significantly reduced in CF and CFRD compared to control and nCFRD, respectively. In addition, gamma-glutamylglycine and L-5-hydroxytryptophan (5-HTP) had the highest discrimination between CFRD and nCFRD with AUC (0.716 and 0.683, respectively). Conclusions: These biomarkers might serve as diagnostic biomarkers and aid in understanding potential metabolic changes linked to CF and CFRD. |

Collection ID: | CO002912 |
Collection Summary: | CF patients (n=36) and age- and gender-matched healthy controls (n=36) were enrolled in this study. Among 36 patients with CF, nine patients had CFRD. The institutional review board at King Faisal Specialist Hospital and Research Center (KFSHRC) approved this study (RAC# 2160 031). The exclusion criteria were patients who participated in other clinical studies in the last 30 days and were unable or unwilling to provide informed consent. The samples were collected as previously described [17]. In brief, blood samples were taken from adult CF patients who visited the adult CF-Pulmonology clinic at the King Faisal Specialist Hospital and Research Center (KFSHRC) in Riyadh, Saudi Arabia. The samples were centrifugated to separate the serum and frozen at −80 ◦C for further analysis. |

Sampleprep Summary: | A standard procedure was used for metabolite extraction [18]. Briefly, metabolites were extracted from plasma samples by adding an extraction solvent of ACN: MeOH (1:1) followed by vortexing at 600 rpm, 4 °C for 1 hour in Thermomixer (Eppendorf, Germany). The samples were then centrifugated at 16000 rpm for 10 min at 4°C. Subsequently, the supernatant was dried using SpeedVac (Christ, Germany) and resuspended in 100 ul of 50% A: B mobile phase before LC/MS analysis. (A: 0.1% Formic acid in dH2O, B: 0.1% FA in 50% ACN: MeOH). Pooled QC was prepared from all samples to check the instrument performance. |

Chromatography Summary: | Untargeted metabolomics analyses were performed using LCMS as previously reported [19]. Waters Acquity UPLC system coupled with a Xevo G2-S QTOF mass spectrometer equipped with an electrospray ionization source (ESI) was used. The samples were separated by ACQUITY UPLC and eluted through XSelect (100×2.1mm 2.5 mm) column (Waters Ltd., Elstree, UK). The composition of mobile phase solvent A was 0.1% formic acid in dH2O, and solvent B was 0.1% formic acid in 50% ACN: MeOH. The flow rate was at 0.300 µL/min. The gradient started with 95- 5% A for 16 minutes, followed by 4 min of 5% - 95% A, 1 min of 5-95% A, then 2 min of 95- 5% A. The total run time was 23 minutes with an injection volume of 5 μL. MS spectra were acquired under positive and negative electrospray ionization modes (ESI+, ESI−). MS conditions were as follows: the source and desolvation temperatures were set at 150°C and 500°C (ESI+) or 140 (ESI−), respectively. The capillary voltage was 3.20 kV (ESI+) or 3 kV (ESI−), the cone voltage was 40 V, the desolvation gas flow was 800.0 L/h, cone gas flow was 50 L/h. The collision energies of low and high functions were set off at 10 V and 50 V, respectively, in MSE mode. Data were collected in continuum mode with a MasslynxTM V4.1 workstation (Waters Inc., Milford, MA, USA). |
