Symptoms and Glycemic Control in Young People With Type 1 Diabetes Following SARS-CoV-2 Infection: An Observational Study.

CONTEXT: Data is needed regarding the effect of SARS-CoV-19 infection on young people with established type 1 diabetes. Identifying the disease outcomes, short and long-term sequelae may help to establish an evidence-based prevention and education policy for sick days management and DKA prevention. OBJECTIVE: This work aims to describe clinical manifestations of SARS-CoV-2 infection in children, adolescents, and young adults with established type 1 diabetes (T1D) and explore the effects of COVID-19 on glycemic control and disease course. METHODS: An observational study was conducted at 3 pediatric diabetes clinics in Israel between mid-March 2020 and mid-March 2021. Included were young people with established T1D, age younger than 30 years, who tested positive for SARS-CoV-2 (quantitative real-time polymerase chain reaction). Data were collected from medical files, diabetes devices, and COVID-19 questionnaire. Outcome measures were analyzed by the presence/absence of clinical symptoms (symptomatic/asymptomatic) and by age group (pediatric, < 19 years/young adults, 19-30 years). RESULTS: Of 132 patients, mean age 16.9 ±â€…5.3years, with COVID-19-confirmed infection, 103 (78%) had related symptoms; the most common were headaches, fatigue, fever, and loss of sense of smell. All had a mild disease course, but 4 required hospitalization and 2 cases were directly related to COVID-19 infection (pleuropneumonia in a patient with immunodeficiency syndrome, 1 case of diabetic ketoacidosis). Logistic regression analysis showed that age (odds ratio [OR] = 1.11; 95% CI, 1.01-1.23; P = .033), elevated glucose levels (OR = 5.23; 95% CI, 1.12-24.41; P = .035), and comorbidities (OR = 8.21; 95% CI, 1.00-67.51; P = .050) were positively associated with symptomatic infection. Persistent symptoms occurred in 16.5% of the cohort over a median of 6.7 months; age (OR = 1.14; 95% CI, 1.01-1.29; P = .030) and elevated glucose levels (OR = 3.42; 95% CI, 1.12-10.40; P = .031) were positively associated with persistent symptoms. Usually, no change was reported in glucose levels (64%) except for a temporary deterioration in glycemic control during the short infection period. CONCLUSION: Young people with established T1D experience mild COVID-19 infection. Elevated glucose levels during COVID-19 infection and older age were associated with prolonged disease course.

Dyslipidemia and cardiovascular disease risk factors in patients with type 1 diabetes: A single-center experience.

BACKGROUND: Type 1 diabetes (T1D) contributes to altered lipid profiles and increases the risk of cardiovascular disease (CVD). Youth with T1D may have additional CVD risk factors within the first decade of diagnosis. AIM: To examine risk factors for dyslipidemia in young subjects with T1D. METHODS: Longitudinal and cross-sectional retrospective study of 170 young subjects with T1D (86 males; baseline mean age 12.2 ± 5.6 years and hemoglobin A1c 8.4% ± 1.4%) were followed in a single tertiary diabetes center for a median duration of 15 years. Predictors for outcomes of lipid profiles at last visit (total cholesterol [TC], triglycerides [TGs], low-density lipoprotein-cholesterol [LDL-c], and high-density lipoprotein-cholesterol [HDL-c]) were analyzed by stepwise linear regression models. RESULTS: At baseline, 79.5% of the patients had at least one additional CVD risk factor (borderline dyslipidemia/dyslipidemia [37.5%], pre-hypertension/hypertension [27.6%], and overweight/obesity [16.5%]) and 41.6% had multiple (≥ 2) CVD risk factors. A positive family history of at least one CVD risk factor in a first-degree relative was reported in 54.1% of the cohort. Predictors of elevated TC: family history of CVD (ß[SE] = 23.1[8.3], P = 0.006); of elevated LDL-c: baseline diastolic blood pressure (DBP) (ß[SE] = 11.4[4.7], P = 0.003) and family history of CVD (ß[SE] = 20.7[6.8], P = 0.017); of elevated TGs: baseline DBP (ß[SE] = 23.8[9.1], P = 0.010) and family history of CVD (ß[SE] = 31.0[13.1], P = 0.020); and of low HDL-c levels: baseline DBP (ß[SE] = 4.8[2.1], P = 0.022]). CONCLUSION: Our findings suggest that elevated lipid profiles are associated with DBP and a positive family history of CVD. It is of utmost importance to prevent and control modifiable risk factors such as these, as early as childhood, given that inadequate glycemic control and elevation in blood pressure intensify the risk of dyslipidemia.

Low dose palliative radiotherapy for splenomegaly in hematologic disorders.

Splenomegaly (SM) is a common complication in hematologic disorders often associated with hypersplenism, and may cause pain, epigastric discomfort and variable systemic effects due to cytopenias. We retrospectively evaluated the results of palliative splenic irradiation (PSI) in terms of symptomatic relief in patients with hematologic disorders. In 1998-2006, 32 patients with hematologic disorders (median age 57) received 52 courses of PSI for SM. Twenty-one patients (66%) were diagnosed with myeloproliferative disorders (MPD), five patients (16%) had malignant lymphoma (ML), five patients (16%) had chronic lymphocytic leukemia (CLL) and one patient (3%) had hairy cell leukemia. Splenomegaly was accompanied by pain, anemia, thrombocytopenia and cachexia. Radiation therapy to the entire spleen was delivered by two parallel opposed fields using 0.5 Gy daily fractions given 5 days per week to a total dose of 6-10 Gy. PSI resulted in splenic size reduction in 78.8%, improvement of anemia in 75% and improvement of thrombocytopenia in 63.5% of PSI courses. The median survival (MS) of patients with MPD, CLL and ML was 45, 10 and 5 months, respectively. The MS of responders to PSI versus non-responders was 45 and 16 months, respectively (hazard ratio 0.17; p = 0.03; 95% confidence interval 0.035-0.84). In our hands, low dose PSI provided effective palliation for patients with hematologic disorders with SM. Splenic re-irradiation was feasible without excessive toxicity.
