Neonatal abstinence syndrome is a potential cause of low TREC copy number

Adil Adatia, Ling Ling, Pranesh Chakraborty, Lauren Brick, Rae Brager
2021 Allergy, Asthma & Clinical Immunology  
We report 3 newborns with neonatal abstinence syndrome who presented with decreased TREC copy number.  ...  Many jurisdictions use the quantitation of T cell receptor excision circles (TRECs) to screen for SCID in newborns, but false positives may be seen in several conditions.  ...  Various medical conditions have been reported to cause low TREC values in the absence of defined immune deficiency syndromes.  ...

Leila Shakerian, Zahra Pourpak, Somayeh Shamlou, Erna Domsgen, Anoshirvan Kazemnejad, Hossein Dalili, Maryam Nourizadeh
2019 Iranian Journal of Allergy, Asthma and Immunology  
In this study, we aimed to explore the effects of demographic variables including age, gender, weight, height and ethnicity on these two episomal DNA molecules.  ...  TREC and KREC copies were markedly reduced with increasing age. Although the levels of TREC and KREC were higher in females than males, this difference did not reach statistical significance.  ...  Our results indicated low levels of both TREC and KREC values in DBS samples of twoautosomal recessive SCID patients (P1 and P2) which agrees with previous reports. 4, 7, 9 However, both XLA patients  ...

Improving retrieval feedback with multiple term-ranking function combination

Claudio Carpineto, Giovanni Romano, Vittorio Giannini
2002 ACM Transactions on Information Systems  
An analytical comparison shows that the retrieval performance of methods based on distinct term-scoring functions is comparable on the whole query set but considerably differs on single queries, consistent  ...  The combined retrieval feedback method is effective not only with respect to unexpanded queries but also to any individual method, with notable improvements on the system's precision.  ...  In Figure 1 and Figure 2 we report, for each query, the minimum and maximum of such differences on the test collections TREC-8 and TREC-9.  ...

Clinical significance of T cell receptor excision circle (TREC) quantitation after allogenic HSCT

Neveen Lewis Mikhael, Manal Elsorady
2019 Blood Research  
The study was conducted on 100 patients receiving allogenic HSCT from an HLA identical sibling. TREC quantification was done by real time PCR using a standard curve.  ...  The immune recovery of T cells relies on peripheral expansion of mature graft cells, followed by differentiation of donor-derived hematopoietic stem cells.  ...  Previous studies have not measured TREC levels before three months post-transplant, nor have they reported the full recovery of TRECs before 3-9 months [17] [18] [19] .  ...
