Post-COVID syndrome, inflammation, and diabetes.

The raging COVID-19 pandemic is in its third year of global impact. The SARS CoV 2 virus has a high rate of spread, protean manifestations, and a high morbidity and mortality in individuals with predisposing risk factors. The pathophysiologic mechanisms involve a heightened systemic inflammatory state, cardiometabolic derangements, and varying degrees of glucose intolerance. The latter can be evident as significant hyperglycemia leading to new-onset diabetes or worsening of preexisting disease. Unfortunately, the clinical course beyond the acute phase of the illness may persist in the form of a variety of symptoms that together form the so-called "Long COVID" or "Post-COVID Syndrome". It is thought that a chronic, low-grade inflammatory and immunologic state persists during this phase, which may last for weeks or months. Although numerous insights have been gained into COVID-related hyperglycemia and diabetes, its prediction, course, and management remain to be fully elucidated.

Newly Diagnosed Diabetes Mellitus During COVID-19: The New Pandemic - A Literature Review.

Purpose of Review: Coronavirus disease 2019 (COVID-19) has caused a spike in newly diagnosed diabetes mellitus (NDDM). NDDM and COVID-19 infection are not well established as a cause-and-effect relationship; hence, the present review aims to define the underlying causes and consequences of COVID-19 infection in relation to the condition. Recent Findings: ß-Cells are infiltrated by SARS-CoV-2, causing glycometabolic dysfunction and insulin dysregulation. The disease causes systemic inflammation and pro-inflammatory cytokines, as well as hormonal changes that lead to insulin resistance and hyperglycemia that are difficult to manage. As a result of NDDM, complications related to COVID-19 infection become more severe. Summary: NDDM related to COVID-19 infection complicates hospitalization outcomes and adversely affects quality of life in patients. There are many possible causes and consequences associated with NDDM, but for establishing preventive measures and treatments for NDDM, more evidence regarding its epidemiology, physiopathology, etiology, and nutritional aspects is required.

Newly diagnosed diabetes vs. pre-existing diabetes upon admission for COVID-19: Associated factors, short-term outcomes, and long-term glycemic phenotypes.

AIMS: High rates of newly diagnosed diabetes mellitus (NDDM) have been reported in association with coronavirus disease-2019 (COVID-19). Factors associated with NDDM and long-term glycemic outcomes are not known. METHODS: Retrospective review of individuals admitted with COVID-19 and diabetes mellitus (DM; based on labs, diagnoses, outpatient insulin use, or severe inpatient hyperglycemia) between March and September 2020, with follow-up through July 2021. RESULTS: Of 1902 individuals admitted with COVID-19, 594 (31.2%) had DM; 77 (13.0%) of these had NDDM. Compared to pre-existing DM, NDDM was more common in younger patients and less common in those of non-Hispanic White race/ethnicity. Glycemic parameters were lower and inflammatory markers higher in patients with NDDM. In adjusted models, NDDM was associated with lower insulin requirements, longer length of stay, and intensive care unit admission but not death. Of 64 survivors with NDDM, 36 (56.3%) continued to have DM, 26 (40.6%) regressed to normoglycemia or pre-diabetes, and 2 were unable to be classified at a median follow-up of 323 days. CONCLUSIONS: Diabetes diagnosed at COVID-19 presentation is associated with lower glucose but higher inflammatory markers and ICU admission, suggesting stress hyperglycemia as a major physiologic mechanism. Approximately half of such individuals experience regression of DM.

Newly-Diagnosed Diabetes and Sustained Hyperglycemia are Associated with Poorer Outcomes in COVID-19 Inpatients Without Pre-Existing Diabetes.

PURPOSE: To analyze the impact of hyperglycemia on the clinical outcome of COVID-19 in patients with newly diagnosed diabetes (NDD). PATIENTS AND METHODS: We performed a retrospective study of 3114 cases of COVID-19 without pre-existing diabetes, 351 of which had NDD, in Hubei Province, China. The Cox regression model was used to calculate the risk of adverse clinical outcomes comparing the NDD vs non-NDD group before and after propensity score-matched (PSM) analysis. Patients with NDD were further divided into a sustained hyperglycemia group, a fluctuating group, and a remitted group based on their blood glucose levels during hospitalization as well as into hypoglycemic agent users and nonusers. RESULTS: Compared to the non-NDD individuals, individuals with NDD had a significantly increased risk of all-cause mortality (adjusted HR after PSM, 2.65; 95% CI, 1.49-4.72; P = 0.001) and secondary outcomes involving organ damage during the 28-day follow-up period. Subgroup analyses indicated that among individuals with NDD, the individuals with remitted hyperglycemia had the lowest 28-day mortality, whereas those with sustained hyperglycemia had the highest (IRR 24.27; 95% CI, 3.21-183.36; P < 0.001). Moreover, individuals treated with hypoglycemic agents had significantly lower all-cause mortality than those not treated with hypoglycemic agents (IRR 0.08; 95% CI, 0.01-0.56; P < 0.001). CONCLUSION: Our study reinforces the clinical message that NDD is strongly associated with poor outcomes in COVID-19 patients. Furthermore, resolved hyperglycemia in the later phase of the disease and the use of hypoglycemic agents were associated with improved prognosis in patients with NDD.

A Prospective Study on Type-2 Diabetic Complications and Efficacy of Integrated Yoga: A Pan India 2017.

BACKGROUND: Type 2 diabetes (T2DM) contributes to high mortality and morbidity because of its major complications related to kidney, heart, brain, and eyes. It also poses a high risk for mortality because of COVID-19. Studies suggest the possible implications of Yoga in delaying or attenuating such complications. METHODOLOGY: This was a pan-India multi centered cluster-randomized (4 level) two-armed trial in the rural and urban population of all populous states of India. Data were obtained using mobile app in all adults in the household of the selected clusters. RESULTS: We report the diabetes related complications in 16623 adults (48% males, 52% females) from 65 districts (1 in 10 districts, 2011 census) of 29 (out of 35) states and Union Territories of India; mean age was 48.2 ± 12.46 years. Out of this 40% lived in rural and 62% in urban locations. In high risk diabetes individuals (scored ≥ 60 points on Indian diabetes risk score key), 18.0% had self-reported history of (peripheral neuropathy, 6.1% had h/o major strokes, 5.5% had minor strokes (transient ischemic episodes), 18.1% had lower limb claudication, 20.5% leg ulcers, 4.4% had h/o cardiac surgery, 4.8% angioplasty, and 15.1% had diabetes retinopathy. Complications were higher in rural than in urban areas, higher in people with extended duration of diabetes. Integrated yoga module for three months (one hour daily) showed significantly better reduction in symptoms related to complications as compared to control group (P < .001). CONCLUSION: The alarming high prevalence of complications in diabetes population calls for urgent action, where yoga may show the benefits in reduction of symptoms of complications.

Newly diagnosed diabetes in patients with mild to moderate COVID-19.

BACKGROUND AND AIMS: We aimed to study newly diagnosed diabetes in patients with mild to moderate COVID-19. METHODS: This was a retrospective cohort study of COVID-19 patients who were admitted to a tertiary care hospital in India from May to October 2020. RESULTS: Of 102 patients, 21 (20.6%) had newly diagnosed diabetes on admission. Of which, four (19.0%) had marked hyperglycemia with no ketosis or ketoacidosis. CONCLUSION: In this study of patients with mild to moderate COVID-19, newly diagnosed diabetes and marked hyperglycemia in those with newly diagnosed diabetes were common.

Severe diabetic ketoacidosis and coronavirus disease 2019 (COVID-19) infection in a teenage patient with newly diagnosed diabetes.

Objectives Recently, World Health Organization has declared coronavirus disease 2019 (COVID-19) infection a pandemic. Patients with diabetes may be at an increased risk of developing COVID-19 infection, as well as increased risk of morbidity and mortality. Although the current data have shown that the coronavirus infection generally has a milder course in children. Case presentation In this case report, we present a teenage patient with severe diabetic ketoacidosis (DKA) as the first manifestation of his diabetes and COVID-19 infection. Conclusions He was treated for DKA and COVID-19 infection, and fortunately, had a good response to the treatment.
