Best insight from top research papers

Low neutrophil levels persisting for an extended period, such as 3 years, can indicate a condition known as late-onset neutropenia, which has been observed in very low birth weight (VLBW) infants . This phenomenon is characterized by a decrease in absolute neutrophil count (ANC) at a postnatal age of ≥3 weeks, with the duration of neutropenia typically lasting around 1.7 weeks. Late-onset neutropenia is often detected in stable, growing VLBW infants and is associated with anemia of prematurity and marked reticulocytosis. Despite the low neutrophil levels, infants with late-onset neutropenia are usually asymptomatic and do not exhibit signs of sepsis, suggesting that this condition may not have adverse effects on these infants' health .

What can be the reasons for low T3 in CSF?4 answersLow T3 in cerebrospinal fluid (CSF) can be caused by several factors. One possible reason is the disruption of the local intracerebral conversion process, leading to increased levels of reverse triiodothyronine (rT3) in the CSF. Another potential cause is the development of isolated syndrome in the brain, characterized by specific thyroidal metabolic disorders, which the authors propose to call the cerebral low T3 syndrome. Additionally, low T3 in CSF can be associated with neurocritical conditions, such as acute subarachnoidal hemorrhage and neurocritical events, leading to a depression of thyroidal metabolism. It is important to note that these studies focus on specific patient populations and conditions, and further research is needed to fully understand the mechanisms behind low T3 in CSF.
