Symptomatic hypercalcemia in an infant secondary to excessive consumption of almond milk as a formula alternative.

A 4-month-old previously healthy female presented with persistent nonbloody, nonbilious emesis, decreased urine output, weight loss, fussiness, and lethargy. Serum levels of calcium were increased at 14.1 mg/dL, serum phosphate decreased at 1.6 mg/dL, and serum parathyroid hormone decreased at <4 pg/mL. The patient had been consuming unsweetened almond milk due to inability to find infant formula during a national infant formula shortage. Milk alternatives including almond milk are calorie-poor, low fat, low protein, and too high in free water and calcium to safely be the primary nutrition source for infants.

Type 1 Diabetes Overview and Perioperative Management.

Type 1 diabetes (T1D) is an increasingly common condition. Although often more effective, treatment regimens for patients with T1D have become more variable and complex with newer insulin analogues and increasing use of diabetes technology. Both surgery and anesthesia are known to trigger a stress response that causes dramatic metabolic changes in the patient that tend to increase glucose variability. Close monitoring of glucose levels and clear algorithms for insulin administration can ameliorate these characteristic responses. As T1D treatment technology becomes more effective at maintaining glucose in target range, there should be more consideration of using this technology during hospitalization and surgery.

Diabetic ketoacidosis drives COVID-19 related hospitalizations in children with type 1 diabetes.

BACKGROUND: Diabetes is a risk factor for poor COVID-19 outcomes, but pediatric patients with type 1 diabetes are poorly represented in current studies. METHODS: T1D Exchange coordinated a US type 1 diabetes COVID-19 registry. Forty-six diabetes centers submitted pediatric cases for patients with laboratory confirmed COVID-19. Associations between clinical factors and hospitalization were tested with Fisher's Exact Test. Logistic regression was used to calculate odds ratios for hospitalization. RESULTS: Data from 266 patients with previously established type 1 diabetes aged <19 years with COVID-19 were reported. Diabetic ketoacidosis (DKA) was the most common adverse outcome (n = 44, 72% of hospitalized patients). There were four hospitalizations for severe hypoglycemia, three hospitalizations requiring respiratory support (one of whom was intubated and mechanically ventilated), one case of multisystem inflammatory syndrome in children, and 10 patients who were hospitalized for reasons unrelated to COVID-19 or diabetes. Hospitalized patients (n = 61) were more likely than nonhospitalized patients (n = 205) to have minority race/ethnicity (67% vs 39%, P < 0.001), public insurance (64% vs 41%, P < 0.001), higher A1c (11% [97 mmol/mol] vs 8.2% [66 mmol/mol], P < 0.001), and lower insulin pump and lower continuous glucose monitoring use (26% vs 54%, P < 0.001; 39% vs 75%, P < 0.001). Age and gender were not associated with risk of hospitalization. Higher A1c was significantly associated with hospitalization, with an odds ratio of 1.56 (1.34-1.84) after adjusting for age, gender, insurance, and race/ethnicity. CONCLUSIONS: Higher A1c remained the only predictor for hospitalization with COVID-19. Diabetic ketoacidosis is the primary concern among this group.

Inequities in Diabetic Ketoacidosis Among Patients With Type 1 Diabetes and COVID-19: Data From 52 US Clinical Centers.

OBJECTIVE: We examined whether diabetic ketoacidosis (DKA), a serious complication of type 1 diabetes (T1D) was more prevalent among Non-Hispanic (NH) Black and Hispanic patients with T1D and laboratory-confirmed coronavirus disease 2019 (COVID-19) compared with NH Whites. METHOD: This is a cross-sectional study of patients with T1D and laboratory-confirmed COVID-19 from 52 clinical sites in the United States, data were collected from April to August 2020. We examined the distribution of patient factors and DKA events across NH White, NH Black, and Hispanic race/ethnicity groups. Multivariable logistic regression analysis was performed to examine the odds of DKA among NH Black and Hispanic patients with T1D as compared with NH White patients, adjusting for potential confounders, such as age, sex, insurance, and last glycated hemoglobin A1c (HbA1c) level. RESULTS: We included 180 patients with T1D and laboratory-confirmed COVID-19 in the analysis. Forty-four percent (n = 79) were NH White, 31% (n = 55) NH Black, 26% (n = 46) Hispanic. NH Blacks and Hispanics had higher median HbA1c than Whites (%-points [IQR]: 11.7 [4.7], P < 0.001, and 9.7 [3.1] vs 8.3 [2.4], P = 0.01, respectively). We found that more NH Black and Hispanic presented with DKA compared to Whites (55% and 33% vs 13%, P < 0.001 and P = 0.008, respectively). After adjusting for potential confounders, NH Black patients continued to have greater odds of presenting with DKA compared with NH Whites (OR [95% CI]: 3.7 [1.4, 10.6]). CONCLUSION: We found that among T1D patients with COVID-19 infection, NH Black patients were more likely to present in DKA compared with NH White patients. Our findings demonstrate additional risk among NH Black patients with T1D and COVID-19.

A phase I study of anti-inflammatory therapy with rilonacept in adolescents and adults with type 1 diabetes mellitus.

BACKGROUND: The innate immune system may be activated around the time of diagnosis of type 1 diabetes (T1D). Components of this system, including cytokines such as interleukin-1ß (IL-1ß) represent potential therapeutic targets for disease modifying therapy. OBJECTIVE: We conducted a phase 1 trial of rilonacept, an IL-1 cytokine trap, in patients with T1D. SUBJECTS AND METHODS: Thirteen T1D patients (10 males) with median age (interquartile range, IQR) of 17 years (16-18), a median (IQR) of 5 months (5-7) since diagnosis. Rilonacept was administered subcutaneously for 26 weeks. Incidence of infections was the primary end-point. RESULTS: There were 85 adverse events; 13 were Grade 2, of which 9 (8 infectious) were judged "possibly related" to the drug. The mean (SD) C-peptide on 2-hour mixed meal tolerance tests decreased from 0.87 (0.42) to 0.59 (0.29) ng/mL (P = .01 by paired t test) during 6 months on treatment. Hemoglobin A1c (HbA1c) increased from 6.8 (1.1) to 7.3 (1.1) (P = .05), but there was not a significant change in daily insulin dose (0.41 ± 0.23 to 0.47 ± 0.18), or in insulin dose-adjusted HbA1c (IDAA1c, 8.4 ± 1.8 to 9.0 ± 1.5). Subjects in "remission," defined as HbA1c <6.5 and a total daily insulin dose <0.5 units/kg/24 h, decreased from 5 to 4. There were no significantly differentially expressed genes in peripheral blood leukocytes before and after rilonacept. CONCLUSIONS: Rilonacept treatment for 6 months is well-tolerated in individuals with T1D of recent onset, but is unlikely to be efficacious as a single agent in preserving beta cell function.

Preliminary studies related to anti-interleukin-1ß therapy in children with newly diagnosed type 1 diabetes.

BACKGROUND: Interleukin-1ß (IL-1ß) may play a role in the pathogenesis of type 1 diabetes, but there are no data regarding the efficacy of agents antagonizing IL-1ß in patients with this disorder. We characterized the effects of IL-1ß on gene expression in peripheral blood mononuclear cells (PBMC) and the clinical and gene expression effects of a short course of recombinant IL-1 receptor antagonist protein, anakinra, on children with newly diagnosed diabetes. METHODS: PBMC from healthy adult volunteers were exposed to IL-1ß for 24 h in vitro. Gene expression was analyzed via microarray. Fifteen children within 1 wk of diagnosis of type 1 diabetes received daily anakinra for 28 d and were followed for 6 months. Blood was drawn for microarray analysis before and after anakinra treatment. Insulin secretory capacity was assessed by mixed-meal tolerance testing (MMTT) at 3-4 wk and 7 months after diagnosis. Hemoglobin A1c (HbA1c) and insulin doses were periodically recorded. Data were compared with two historical control groups of children with newly diagnosed diabetes. RESULTS: Although in vitro exposure to IL-1ß caused many changes in PBMC gene expression, gene expression did not change significantly after anakinra therapy in diabetes patients. Anakinra-treated patients had similar HbA1c and MMTT responses, but lower insulin requirements 1 and 4 months after diagnosis compared to controls, and lower insulin-dose-adjusted A1c 1 month after diagnosis. CONCLUSIONS: Anakinra therapy is well tolerated in children with newly diagnosed type 1 diabetes. Further studies are needed to demonstrate biological effects.
