ABSTRACT

OBJECTIVE: Recent reports have suggested a link between COVID-19 infection and subacute thyroiditis (SAT). We aimed to describe variations in clinical and biochemical parameters in patients developing post-COVID SAT. DESIGN: Ours was a combined retrospective-prospective study on patients presenting with SAT within 3 months of recovery from COVID-19 infection, who were subsequently followed up for a further 6 months since diagnosis of SAT. RESULTS: Out of 670 patients with COVID-19, 11 patients presented with post-COVID-19 SAT (6.8%). Those with painless SAT (PLSAT, n = 5) presented earlier, had more severe thyrotoxic manifestations and exhibited higher C-reactive protein, interleukin 6 (IL-6), neutrophil-lymphocyte ratio and lower absolute lymphocyte count than those with painful SAT (PFSAT, n = 6). There were significant correlations of total and free T4 and total and free T3 levels with serum IL-6 levels (pall <0.04). No differences were observed between patients with post-COVID SAT presenting during the first and second waves. Oral glucocorticoids were needed for symptomatic relief in 66.67% of patients with PFSAT. At 6 months of follow-up, majority (n = 9, 82%) achieved euthyroidism, while subclinical and overt hypothyroidism were found in one patient each. CONCLUSIONS: Ours is the largest single-centre cohort of post-COVID-19 SAT reported until, demonstrating two distinct clinical presentations-without and with neck pain-depending on time elapsed since COVID-19 diagnosis. Persistent lymphopaenia during the immediate post-COVID recovery period could be a key driver of early,painless SAT. Close monitoring of thyroid functions for at least 6 months is warranted in all cases.

ABSTRACT

AIM: To compare admission-blood-glucose (ABG) or stress-hyperglycemia-ratio (SHR) performs better in predicting mortality and worse outcomes in COVID-19 patients with (DM) and without known Type 2 Diabetes Mellitus (UDM). METHODS: ABG and SHR were tested for 451 patients with moderate-severe COVID-19 infection [DM = 216,47.9%; pre-diabetes = 48,10.6%, UDM = 187,41.4%],who were followed-up to look for in-hospital-mortality (primary outcome) and secondary outcomes (ICU stay or mechanical ventilation, hospital-acquired-sepsis and multiple organ dysfunction syndrome [MODS]). Those with and without SHR ≥ 1.14 were compared; logistic regression was done to identify predictors of outcomes, with subgroup analysis based on pre-existing DM status and COVID-19 severity. RESULTS: Those who died (n = 131) or developed ≥ 1 secondary outcomes (n = 218) had higher prevalence of SHR ≥ 1.14, ABG ≥ 180 mg/dl and higher median SHR (pall < 0.01). Those with SHR ≥ 1.14 had higher mortality (53.7%), higher incidence of ≥ 1 secondary outcomes (71.3%) irrespective of pre-existing diabetes status. SHR ≥ 1.14, but not ABG ≥ 180 was an independent predictor of mortality in the whole group (OR: 7.81,4.07-14.98), as also the DM (OR:10.51,4.34-25.45) and UDM (5.40 (1.57-18.55) subgroups. SHR ≥ 1.14 [OR: 4.41 (2.49-7.84)] but not ABG ≥ 180 could independently predict secondary outcomes AUROC of SHR in predicting mortality was significantly higher than ABG in all subgroups. CONCLUSION: SHR better predicts mortality and adverse outcomes than ABG in patients with COVID-19, irrespective of pre-existing chronic glycemic status.

ABSTRACT

BACKGROUND: Recent literature suggests a bi-directional relationship between COVID-19 infection and diabetes mellitus, with an increasing number of previously normoglycemic adults with COVID-19 being admitted with new-onset diabetic ketoacidosis (DKA). However, the possibility of COVID-19 being a potential trigger for A-ß + ketosis-prone diabetes (KPD) in these patients needs elucidation. Our study aimed at analyzing such a cohort of patients and determining their natural course of ß-cell recovery on serial follow-up. METHODS: After initial screening, n = 42 previously non-diabetic patients with new-onset DKA and RT-PCR positive COVID-19, were included in our ten-month follow-up study. Of these, n = 22 were negative (suspected A-ß + KPD) and n = 20 were positive (Type 1A DM) for autoantibodies (GAD/IA-2/ZnT8). Subsequently, n = 19 suspected KPD and n = 18 Type 1A DM patients were followed-up over ten months with serial assessments of clinical, biochemical and ß-cell secretion. Amongst the former, n = 15 (79%) patients achieved insulin independence, while n = 4 (21%) continued to require insulin at ten-months follow-up. RESULTS: On comparison, the suspected KPD patients showed significantly greater BMI, age, Hba1c, IL-6 and worse DKA parameters at presentation. Serial C-peptide estimations demonstrated significant ß-cell recovery in KPD group, with complete recovery seen in the 15 patients who became insulin independent on follow-up. Younger age, lower BMI, initial severity of DKA and inflammation (IL-6 levels), along-with reduced 25-hydroxy-Vitamin-D levels were associated with poorer recovery of ß-cell secretion at ten-month follow-up amongst the KPD patients, CONCLUSIONS: This is the first prospective study to demonstrate progressive recovery of ß-cell secretion in new-onset A-ß + KPD provoked by COVID-19 infection in Indian adults, with a distinctly different profile from Type 1A DM. Given their significant potential for ß-cell recovery, meticulous follow-up involving C-peptide estimations can help guide treatment and avoid injudicious use of insulin.

ABSTRACT

Electrical storm or incessant ventricular tachycardia is a life-threatening condition and is associated with high morbidity and mortality. Often patients respond to traditional anti-arrhythmia treatment. However, some patients are resistant to the drug therapy and thus, pose huge challenges in effective management. Though stellate ganglion block has been found to be effective in treating patients with electrical storm, it is still under-utilized. In this case report, we successfully managed to revert the drug-resistant arrhythmia to sinus rhythm after ultrasound-guided stellate ganglion block. Earlier utilization of the block can possibly provide effective treatment in drug-resistant ventricular arrhythmias and prevent morbidity and mortality.

ABSTRACT

BACKGROUND AND AIM: COVID-19 infection predisposes to diabetic ketoacidosis(DKA); whether glucocorticoids enhances this risk is unknown.We aimed to study the occurrence of DKA after initiating glucocorticoids in patients with type 2 diabetes mellitus(T2DM) and moderate-to-severe COVID-19, and identify predictors for it. METHODS: Patients with T2DM and moderate or severe COVID-19 infection were prospectively observed for development of new-onset DKA for one week following initiation of parenteral dexamethasone. Clinical and biochemical parameters were compared between those who developed DKA (Group A) and those who didnot (Group B). Logistic regression was done to identify independent risk-factors predicting DKA; ROC-curve analysis to determine cut-offs for the parameters in predicting DKA. RESULTS: Amongst 302 patients screened, n = 196 were finally included, of whom 13.2% (n = 26,Group A) developed DKA. Patients in Group A were younger, had lower BMI, increased severity of COVID-19 infection, higher HbA1c%, CRP, IL-6, D-dimer and procalcitonin at admission (pall < 0.02). Further, admission BMI (OR: 0.43, CI: 0.27-0.69), HbA1c % (OR: 1.68, CI: 1.16-2.43) and serum IL-6 (OR: 1.02, CI: 1.01-1.03) emerged as independent predictors for DKA. Out of these, IL-6 levels had the highest AUROC (0.93, CI: 0.89-0.98) with a cut-off of 50.95 pg/ml yielding a sensitivity of 88% and specificity of 85.2% in predicting DKA. CONCLUSION: There is significant incidence of new-onset DKA following parenteral glucocorticoids in T2DM patients with COVID-19, especially in those with BMI <25.56 kg/m2, HbA1c% >8.35% and IL-6 levels >50.95 pg/ml at admission.

ABSTRACT

Cystatin C has been regarded as a novel sensitive marker for the assessment of renal function, and the role of cystatin C as a predictor of cardiovascular events in patients with impaired renal function has been confirmed in clinical studies. In this study we assessed the association between cystatin C and Coronary artery disease [CAD] in a consecutive series of patients with normal kidney function in order to avoid the well-known effect of overt renal insufficiency on coronary atherosclerosis, and evaluate whether cystatin C has an ability to identify individuals at a higher risk for CAD among patients belonging to a low-risk category according to estimated glomerular filtration rate .The current study and review of literature demonstrated that serum levels of cystatin C, were independently associated with the development of CAD.
