After study enrollment, all subjects started anakinra (Kineret™; Amgen, Thousand Oaks, CA, USA) as a subcutaneous daily injection. Subjects weighing >25 kg at the time of enrollment received 100 mg daily, whereas those weighing <25 kg received 50 mg daily. Anakinra was continued for 28 d with no dose adjustment.

Patients at Children's Medical Center Dallas between ages 6 and 18 years with Type 1 diabetes within one week of diagnosis were eligible.
Diabetes care. At diagnosis, all subjects were placed on a basal-bolus insulin regimen with glargine and either lispro or aspart. For the duration of the study, insulin doses were adjusted per standard clinic protocol with target glucose of 80-140 mg/dL fasting and 80-180 mg/dL before meals. At each study visit, we recorded the subject's current insulin doses and weight to allow calculation of the total daily dose (units/kg/day).
Anakinra. After study enrollment, all subjects started anakinra (Kineret; Amgen, Thousand Oaks, CA) as a subcutaneous daily injection. Subjects weighing more than 25 kg at the time of enrollment received 100 mg daily whereas those weighing 25 kg or less received 50 mg daily. Anakinra was continued for a total of 28 days with no dose adjustment.

Expression data at baseline and after treatment were available on 10 patients who had received anakinra. These were compared to similarly-timed samples from 10 patients from control group B. Several attempts have been made to contact the PI to verify information, but were unsuccessful. Unable to verify if 10 or 12 patients were analyzed.

Mixed-meal tolerance tests. MMTTs were conducted at the UT Southwestern Clinical Translational Research Center (CTRC). Subjects underwent MMTTs at 3-4 wk after diagnosis and again at 7 months after diagnosis. C-peptide analyses were performed by Dr Philip Raskin (UTSouthwestern MedicalCenter, Dallas, TX,USA). C-peptide AUC was calculated for each MMTT using the trapezoidal method. C-peptide AUC data between groups were rank transformed and then analyzed using a two-way repeated measures analysis of variance (ANOVA).

Patients at Children's Medical Center Dallas between ages 6 and 18 yr with type 1 diabetes within 1 wk of diagnosis were eligible. Exclusion criteria included treatment with systemic or inhaled corticosteroids or any other immunomodulatory drug, active infection, history of mycobacterial disease, pregnancy, live vaccine administration within 90 d of enrollment, and severe comorbidities. Patients were excluded if it was uncertain whether they had type 1 or type 2 diabetes.
