Euthyroid Sick Syndrome (ESS) Effect on Traumatic Brain Injury Patients and Its Relation With GFAP...

Euthyroid Sick Syndromes in Traumatic Brain Injury Patient and GFAP Level

Euthyroid sick syndrome (ESS) effects on patients suffering from traumatic brain injury (TBI) have received little attention. Moreover, there is limited evidence that serum levels of thyroid-related hormones might influence functional outcome in the acute phase of brain damage. However, the relationship is complex, and the relevance for functional outcome and the question of therapeutic interventions remain the subject of ongoing researches . Historically, a wide range of brain damage markers have been examined in TBI patients. However, owing to the limited tissue specificity and other concerns, most markers, including neuro-specific enolase and S100B protein, were compromised in routine clinical use . Glial fibrillary acidic protein (GFAP) was recently reported to have greater prognostic value than other biomarkers in TBI patients as a monomeric intermediate filament protein concentrated in the astroglial cytoskeleton; GFAP is specific to brain tissue and is not routinely found in peripheral blood circulation. However, GFAP is released after astrocyte death, making it an ideal candidate marker for brain injury patients . Several studies have found that the serum levels of GFAP on admission were significantly increased in TBI patients, also a correlation between serum concentrations and the pathological types of brain damage and clinical outcomes were also reported . However, the changes in serum GFAP over time and the associated predictive utility over the acute days post injury are largely unknown. To study the hypothesis of euthyroid sick syndrome (ESS) traumatic brain injury patients and its relation with GFAP.

Can Oral T3 Normalize Thyroid Hormone Levels Following Cardiopulmonary Bypass in Children?

Low T3 Syndrome

Low triiodothyronine (T3) syndrome defines as decrease of T3 levels during critically ill. This decrease of T3 levels was observed after congenital heart surgery using cardiopulmonary bypass. Previous largest study,Triiodothyronine for Infants and Children Undergoing Cardiopulmonary bypass (TRICC) study showed T3 supplementation decreased time to extubation for infants less than 5 months undergoing cardiopulmonary bypass. Intravenous regiment was known effective in maintaining T3 levels during pediatric cardiac surgery. This drug preparation however is not commonly used in many countries due to the relatively high costs and/or the simple lack of availability. The use of oral T3 to treat postoperative low T3 levels in pediatric patients has not been reported so far, although recent adult studies showed benefit in using oral T3 after cardiac surgery. The purpose of this study was to determine if oral T3 supplementation could prevent the decline of serum T3 in children less than 2 years of age undergoing congenital heart surgery using CPB.

Feeding the Critically Ill During Phases of Altered Redox Status

Acute Respiratory Distress SyndromeOxidative Stress2 more

The FEDOX trial is a prospective randomized clinical trial exploring oxidative stress as a mechanism of harm to explain the negative outcomes found in feeding trials that achieved caloric exposure commensurate with the nationally recommended guidelines. Due to its impact on energy metabolism, we will also explore low T3 syndrome's relationship to this mechanism. Finally, we will explore circadian patterns of diurnal/nocturnal TSH fluctuation as a potential biomarker to indicate this mechanism of harm has subsided. This 7-day prospective randomized clinical trial is designed to address the following specific aims (SA) in ICU patients (n=40) with systemic inflammatory response syndrome. SA1) Determine whether provision of enteral nutrition (EN) at 100% of levels in Nationally Recommended Guidelines NRG (25-30 kcals/kg, 100%NRG) early in critical illness increases reactive oxygen species (ROS) production compared to EN at 40% of NRG levels (10-12 kcals/kg, 40%NRG). Subjects will be fasted overnight and randomized to receive either 100% NRG or 40%NRG for 7 days. Plasma F2-isoprostanes will be measured daily and compared between groups through repeated measures analysis. SA2) Determine if EN at 100%NRG interrupts the critical illness induced low T3 syndrome and subsequently further increases the ROS production compared to 40%NRG. Serum thyroid parameters (T3, T4, rT3, TSH) with be measured daily and compared between groups as above. Mediation analysis will be used to determine the proportion of the effect of nutrition group on F2-isoprostane production explained by each thyroid parameter. SA3) Determine if the return of diurnal/noctural fluctuations in TSH is associated with decreased nutrition-induced ROS production. Plasma TSH will be measured twice per day at 0300 and 1800hrs to determine TSH fluctuation. The interaction effect between TSH fluctuation and nutrition group on F2-isoprostane production will be assessed through repeated measures analysis. This study provides vital mechanistic insight into the impact of feeding on oxidative stress during the first week of critical illness, represents an important first step in determining the safest timing and dosage of nutrition support, and sets the foundation for future larger clinical trials on these topics.

An Analysis of the Relative Risk for Low Triiodothyronine Syndrome in Patients With Chronic Radiation...

The Clinical Incidence of Low Triiodothyronine Syndrome

Radiation enteritis (RE) is by simple definition an inflammatory process occurring at the level of the intestines as a response to abdominal or pelvic radiation energy exposure. Due to the dosage of radiation, sensitivity of organs to radiation, and some patient characteristics, RE can present as either an acute or chronic syndrome. Clinical manifestations differ but may include abdominal pain, malabsorption, diarrhea, cachexia, intestinal bleeding, obstruction, and even perforation, which compromise quality of life. For many years, radiotherapy of the abdominal or pelvic region is commonly used for a significant percentage of patients with rectosigmoid and genitourinary system tumors. Different techniques have been developed to prevent the occurrence of radiation induced injury. However, the incidence of CRE is expected to continue to rise during the coming years. What's more, abdominal or pelvic radiotherapy can also lead to other side effects in addition to RE, such as skin desquamation, local soft tissue injury, and so on. Till now, lots of attention is only paid to local complications, there is little report on systemic damage of abdominal or pelvic radiotherapy. Low triiodothyronine syndrome (LT3S), a condition characterized by low circulating triiodothyronine (T3) levels, normal thyroxine (T4), free thyroxine (FT4) and thyroid-stimulating hormone (TSH) levels in the absence of an intrinsic thyroid disease, is variously known as the "nonthyroidal illness syndrome (NTIS)". This condition is frequently detected in critical illness. Reichlin et al. first noticed that some aspects of thyroid hormone metabolism might change during many chronic illnesses as early as 1973. Data has shown that about 35-70% of acute and chronic critical conditions were associated with a significant abnormal thyroid hormone metabolism, of which LT3S was the most common type. Furthermore, these changes have been shown to be associated with disease severity and have been connected with poor short-term prognosis. To date, there are lots of literatures include detailed reports on the relationship between LT3S and chronic illnesses such as rheumatoid arthritis, systemic lupus erythematosus, sepsis, and so on. However, no systematic analysis of LT3S in patients with CRE has been undertaken. As such, the present study aimed to investigate the frequency of LT3S in CRE patients.
