The Severity Of Obstructing Tubulopathy Is Often Associated With Foci Of Renal Tubular Obstruction, Ping L. Zhang, Hassan D. Kanaan, Wei Li

Posters

Etiologies of renal failure due to renal tubular injury may result from either ischemic/toxic injury of proximal tubules (ATN), variants of interstitial nephritis or obstructing tubulopathy by the luminal blocking of either monoclonal casts, uric acid or calcified deposits. Our previous studies indicate that the polarizable semi-transparent calcium oxalate deposits block proximal tubules, whereas monoclonal casts, uric acid deposits and bluish calcium phosphates block the distal tubules. We hypothesized that the serum creatinine (SCr) levels and the number of tubular obstructing deposits were correlated so that pathologic identification of obstructing foci can be predictable for the extent of renal dysfunction.

An Early Successful Hematopoietic Stem Cell Transplant (Hsct) For A Boy With Ipex Syndrome, Ali H. Alnajim, Salman Aljubran

Posters

Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare inborn error of immunity. It affects about one in every 1.6 million people. It is caused by mutations in the forkhead box P3 (FOXP3) gene on chromosome Xp11.23. FOXP3 is a vital regulator of T cell development and function. Dysfunctional FOXP3 allows the hyperactivation of T cells, resulting in skin rash, enteropathy, diabetes, thyroiditis, hemolytic anemia, and thrombocytopenia. The classic clinical presentation is intractable diarrhea, growth problems, dermatitis, and autoimmune endocrinopathy. Case Description: A 4-week-old male was transferred to our hospital’s NICU due to respiratory distress and feeding difficulties. Neurology …

Background Apnea of prematurity is nearly universal among very low birth weight infants (VLBW). In VLBW infants, changes in clinical status usually occur due to sepsis or non-infectious causes and it is challenging to differentiate between the two. We as clinicians use irregularities in vital signs as an early warning sign of sepsis to facilitate early treatment and improve patient outcomes. Adults have used RDW as a marker of worsening respiratory status and mortality from acute respiratory distress syndrome (ARDS). In this study, we seek to investigate elevations in Red Cell Distribution Width (RDW) as markers for culture positive sepsis …

Acute lymphoblastic leukemia in infants (iALL) is a high-risk subtype of childhood leukemia, with poor survival outcomes despite intensive therapies. Rearrangement of KMT2A (KMT2A-r) occurs in 70% of cases and is associated with chemotherapy resistance, early relapse, and rapid leukemic progression, all of which contribute to poor survival outcomes. The most common KMT2A-r in iALL is KMT2A::AFF1 (MLL::AF4), derived from t(4;11)(q21;23). This KMT2A-r generates a driver fusion oncogene which leads to epigenetic dysregulation of target gene transcription. Infant ALL’s cell of origin is thought to be a very early hematopoietic precursor, with transcriptomic studies of iALL blasts showing similarities to …

Rhabdomyolysis As A Cause Of Pth Independent Hypocalcemia In A Child With Acute Influenza Infection, Samhita Bhattarai, Kelsee Halpin

Posters

INTRODUCTION Hypocalcemia is characterized by abnormally low level of calcium in the blood. Normal reference range for calcium for children between 12- 19-year-old is 8.5-10.6 mg/dl . Severe hypocalcemia is considered as serum calcium level of <7 mg/dl and can present with tetany, seizures, and life-threatening cardiac arrhythmias. Etiology of hypocalcemia varies but hypoparathyroidism, pseudohypoparathyroidism and Vitamin D deficiency are some of the most common causes encountered by pediatrician endocrinologists. Association of rhabdomyolysis with hypocalcemia and elevated PTH is a rare presentation that should be considered, particularly for those children presenting with acute viral illness. We present a rare case of rhabdomyolysis associated with hypocalcemia not related to hypoparathyroidism. CASE A 12-year-old female presented to the emergency department with body ache, decreased oral intake and vomiting. She was found to be influenza positive. Electrolytes showed hypocalcemia (4.8 mg/dl). She subsequently had an undetectable 25-OH vitamin D level (<5 ng/ml) and elevated iPTH level (609 pg/ml). We discussed the possibility of her etiology of hypocalcemia to be Vitamin D deficiency although her presentation was atypical at an older age with a negative imaging for rickets, hyperphosphatemia (6.0 mg/dl), and normal alkaline phosphatase (334 unit/L). She also did not have any phenotypic features of Albright’s hereditary osteodystrophy and renal function was within normal limits. She was identified to have elevated creatinine kinase (4829 U/L) supporting rhabdomyolysis secondary to acute influenza as a cause of her hypocalcemia. Rhabdomyolysis, a known complication of influenza infection, causes cell membrane destruction which impairs the normal function of Na-K-ATPase channel. This leads to increase in intracellular sodium activating Na/Ca exchanger which in turn causes influx of calcium intracellularly causing hypocalcemia. Additionally, any injury or infection leads to high phosphorus release from cells due to cell lysis. High phosphorus is also caused by reduced oxidative metabolism in muscles impairing phosphate use. This excess of phosphate then combines with calcium and causes calcium-phosphate complex in soft tissues. Hyperphosphatemia also additionally inhibits 1 alpha hydroxylase limiting formation of calcitriol leading to hypocalcemia. CONCLUSION Our patient had severe hypocalcemia due to influenza-related rhabdomyolysis. Rhabdomyolysis is an important consideration as a cause of hypocalcemia in children, especially with acute viral illness. Accordingly, it is also important to obtain serum electrolytes in patients presenting with rhabdomyolysis as hypocalcemia may lead to complications like seizures and cardiac arrhythmia if not appropriately recognized and treated.

3d Bioprinting The Tumor Microenvironment For Immunotherapy Development, Molly Leyda, Tykeem Manor, John Szarejko, Douglas Myers, John M. Perry

Posters

The tumor microenvironment (TME) is a complex system that plays a crucial role in tumor progression, immune evasion, and therapy resistance. The TME is composed of various cell types, including tumor cells, stromal cells, and immune cells such as macrophages. Macrophages are versatile myeloid cells which can exhibit both pro-tumoral and anti-tumoral functions, depending on their phenotype and the TME context. M1 macrophages have demonstrated promising pro-inflammatory and anti-tumor effects, while tumor associated M2 macrophages (TAMs) play an anti-inflammatory role and promote tumor immune escape. Understanding the complex interactions between TAMs and the TME is, therefore, essential for developing effective …
