| Project Title: | Metabolomics analysis of leprosy patients with type 1 reaction |
| Project Type: | MS qualitative analysis and identification of polyunsaturated fatty acids in retrospective serum samples of leprosy patients with type 1 reaction |
| Project Summary: | Type 1 reaction (T1R) is an acute inflammatory episode that causes severe neuronal damages in patients with leprosy. The factors that trigger this pathology is still unknown, and further studies are needed to understand T1R and to early prevent its start. It is well established that the host immune response is linked to T1R and previous studies indicated that the metabolism of the host also influences the adaptive immune response against M. leprae antigens. Therefore, metabolomics-based analyses of sera from 7 patients with and 9 without T1R were conducted via liquid chromatography–mass spectrometry. The main goal of this project was to determine whether the metabolism of polyunsaturated fatty acids (such as eicosanoids and omega-3 fatty acids) were perturbed in leprosy patients with T1R. |

Collection:
| Collection ID: | CO000909 |
| Collection Summary: | The whole blood (10 mL) was collected in a Vacutainer tube from Becton Dickinson (BD). After collection of the whole blood, it was allowed the blood to clot by leaving it undisturbed at room temperature for 30 minutes. The clot was removed by centrifuging at 1,000–2,000 x g for 10 minutes in a refrigerated centrifuge (4 C). The resulting supernatant is designated serum. The serum samples were aliquoted in 100 microliters and stored in a serum bank at -80C. These samples were collected in the Leprosy Outpatient Unit (Oswaldo Cruz Foundation, Rio de Janeiro, Brazil) and then they were sent in dry ice to Colorado State University, where it was processed and analyzed for metabolomics. At Colorado State University the samples were stored at -80C until processing. |

Sample Preparation:
| Sampleprep ID: | SP000922 |
| Sampleprep Summary: | Serum samples (7 serum samples from leprosy patients with T1R) were pooled prior the extraction. These pooled serum samples were incubated with 3 volumes of cold methanol (100%) for 1 hour at -20C. After this incubation, the samples were centrifuged for 30 minutes at 18,000 xg at 4C to clear the supernatant. The supernatant was then transferred and dried under vacuum. Samples were re-suspended in 80 μl of 50% methanol. Prior to the injections on the LC-MS instrument, the samples were centrifuged for 30 minutes at 18,000 xg at 4oC. |
