Clinical characteristics and outcome in patients with combined diabetic ketoacidosis and hyperosmolar hyperglycemic state associated with COVID-19: A retrospective, hospital-based observational case series.

Aim: One of the risk factors for poor outcome with SARS-CoV-2 infection is diabetes mellitus; diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) are the most serious complications of diabetes mellitus. We aimed to explore the clinical characteristics and outcomes of COVID-19 patients presenting with combined DKA/HHS to our institution.

Methods: A retrospective, hospital based observation case series was performed on patients with SARS-CoV-2 admitted to Intensive Care Unit between 3/20/2020 and 4/20/2020.

The effects of human insulin on antibody formation in pregnant diabetics and their newborns.

We studied the immunogenicity of human insulin in 11 diabetic mothers and their newborns. Serum antibody formation was assayed by two different methods. Upon switching four patients from beef/pork insulin to human insulin, we found that elevated baseline antibody levels in three women decreased, in two to undetectable levels at term.

Effects of vitamin A deficiency and repletion on rat insulin secretion in vivo and in vitro from isolated islets.

We studied the effects of vitamin A deficiency and repletion on rat insulin release and islet cellular retinol binding protein (CRBP) and cellular retinoic acid binding protein (CRABP). Biphasic insulin release from vitamin A-deficient perifused islets was markedly impaired. Release remained impaired with retinoic acid (RA) repletion, 2 micrograms/g diet compared to release from islets of rats repleted with retinol in the form of retinyl palmitate, 4 micrograms/g diet.

Combined phenytoin and salicylate effects on thyroid function tests.

To evaluate the effects of salicylates (ASA) on thyroid function tests (TFT's) in patients already taking phenytoin (DPH), 6 adults received a daily dose of DPH to achieve a steady state serum DPH. ASA was then added stepwise (325, 650, 975 mg q 4hr) at 2-day intervals. TFTs, total serum and free salivary DPH were measured.

Renal hypophosphatemic osteomalacia unmasked by hyperthyroidism.

A case of renal hypophosphatemic osteomalacia (RHO) that was unmasked by hyperthyroidism is presented. The patient presented at age 64 with pathologic leg fractures. There was no family history of osteomalacia or rickets.
