Relative Adrenal Insufficiency in Preterm Very Low Birth Weight Infants With Shock

2014-08-27 03:19:25 | BioPortfolio

Summary

The objective of this study is to estimate the prevalence of relative adrenal insufficiency in preterm very low birth weight infants with and without shock.

Description

Till date, no studies are available that have evaluated the incidence of relative adrenal insufficiency in preterm very low birth weight (VLBW) infants with shock. The focus had been on stable preterm and critically ill preterm infants. Given that steroid treatment improves blood pressure and stabilizes cardiovascular status in preterm infants with volume and pressor-resistant hypotension,it becomes essential to examine the incidence of adrenal insufficiency in this cohort (rather than a broad group of critically ill preterm infants). Moreover, there are no studies on adrenal function in Indian neonates.

The purpose of this study is to compare the levels of basal and stimulated (using low dose [1µg/k] ACTH) cortisol levels in preterm (28-34 weeks gestation) very low birth weight (birth weight 750 gm to 1500 gm) infants with shock in the first week of life requiring vasopressor therapy and matched (gestation, birth weight, postnatal age-matched) hemodynamically stable infants ('control group').

Medical and Biotech [MESH] Definitions

Conditions in which the production of adrenal CORTICOSTEROIDS falls below the requirement of the body. Adrenal insufficiency can be caused by defects in the ADRENAL GLANDS, the PITUITARY GLAND, or the HYPOTHALAMUS.

A condition caused by overwhelming BACTERIAL INFECTIONS or SEPTICEMIA, leading to HEMORRHAGE and NECROSIS of the ADRENAL GLAND. It is characterized by rapidly developing ADRENAL INSUFFICIENCY; HYPOTENSION; and widespread cutaneous PURPURA. This syndrome may occur at any age but is more common in children.

Neoplasm derived from displaced cells (rest cells) of the primordial ADRENAL GLANDS, generally in patients with CONGENITAL ADRENAL HYPERPLASIA. Adrenal rest tumors have been identified in TESTES; LIVER; and other tissues. They are dependent on ADRENOCORTICOTROPIN for growth and adrenal steroid secretion.

The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM.

A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.
