Significance of QTc interval in chronic hypoparathyroidism and its correlates.

CONTEXT: Hypocalcemia predisposes patients with chronic hypoparathyroidism (cHypoPT) to an increased risk of QTc prolongation and life-threatening arrhythmias. Information on clinical and biochemical correlates of QTc in cHypoPT is limited. DESIGN AND SETTING: Observational cohort study at tertiary-care-center. SUBJECTS AND METHODS: Eighty-eight non-surgical cHypoPT (mean age 44.1 ± 15.4 years, 45 males) were assessed for QTc interval and its possible correlates including arrhythmic symptoms (palpitation/giddiness/syncope), serum total-calcium, phosphate, 25(OH)D and iPTH. RESULTS: The mean QTc in HypoPT cohort was 428 ± 34 ms with 13.6% having prolonged QTc. There was a significant inverse correlation between QTc interval and serum total-calcium measured on the same day (r = -0.43, p < 0.001). The mean serum total-calcium was significantly lower in patients with prolonged QTc (7.05 ± 1.94 vs. 8.49 ± 1.01 mg/dL, p = 0.02). 21.6% of cHypoPT patients had arrhythmic symptoms. They had significantly higher mean QTc (p = 0.02) and also tended to have lower mean serum total-calcium during follow-up (p = 0.06). In multivariable regression, female gender, higher current-age, higher BMI, and low serum total-calcium showed significant association with prolonged QTc. For every mg/dL decrease in serum total-calcium, QTc increased by 13 ms. Receiver-operating-characteristic analysis revealed serum total-calcium at cut-off of 8.3 mg/dL discriminated prolonged QTc with area-under-curve being 0.72 [95% CI: 0.51,0.93]. CONCLUSION: One-fifth of cHypoPT had arrhythmic symptoms and a significant proportion had prolonged QTc. This highlights the need for close monitoring of cHypoPT patients for arrhythmic symptoms and QTc prolongation. The serum total-calcium should be maintained to at least 8.3 mg/dL to minimize the risk of potentially life-threatening arrhythmia in cHypoPT.

Cardiopulmonary Outcomes in Covid-19 Patients Discharged From a Tertiary Care Center: A Prospective Study.

To determine the cardiopulmonary changes in the survivors of acute COVID-19 infection at 3-6 month and 6-12 month. We followed up 53 patients out of which 28 (52%) had mild COVID-19 and 25 (48%) had severe COVID-19. The first follow-up was between 3 month after diagnosis up to 6 month and second follow-up between 6 and 12 month from the date of diagnosis of acute COVID-19. They were monitored using vital parameters, pulmonary function tests, echocardiography and a chest computed tomography (CT) scan. We found improvement in diffusing capacity for carbon monoxide (DLCO) with a median of 52% of predicted and 80% of predicted at the first and second follow-up, respectively. There was improvement in the CTSS in severe group from 22 (18-24) to 12 (10-18; p-0.001). Multivariable logistic regression revealed increased odds of past severe disease with higher CTSS at follow-up (OR-1.7 [CI 1.14-2.77]; P = 0.01). Correlation was found between CTSS and DLCO at second follow-up (r2 = 0.36; p < 0.01). Most of patients recovered from COVID-19 but a subgroup of patients continued to have persistent radiological and pulmonary function abnormalities necessitating a structured follow-up.

Coronary artery disease and its vascular associates in patients with chronic nonsurgical hypoparathyroidism.

OBJECTIVE: Patients with chronic hypoparathyroidism (cHypoPT) are prone to intracranial-calcification, cataract and nephrocalcinosis. In this study, we systematically investigated the possibility of increased coronary artery calcification (CAC) and coronary artery disease (CAD) in them. DESIGN: Cross-sectional. PATIENTS AND MEASUREMENTS: Ninety-four nonsurgical cHypoPT (M:F = 50:44; age = 45 ± 15 years) with 18.6 ± 9.3 years of illness were assessed. Those with dyspnoea, angina, syncope, abnormal electrocardiogram, echocardiography or significant CAC underwent coronary angiography or myocardial-perfusion-stress imaging. Their lipid parameters and high-sensitivity C-reactive protein (hsCRP) were compared with age-matched healthy controls (Group A, n = 101). The prevalence of CAC in cHypoPT was compared with that of subjects referred from cardiology-clinics (Group B, n = 148, age = 52 ± 11 years). RESULTS: One of 94 cHypoPT had known CAD. On screening, 17 cHypoPT required evaluation for CAD. Two of 17 had severe coronary stenosis, and 12 showed subclinical CAD. CAC and aortic-valve calcification occurred in 21.5% and 11.8%. Clinical and subclinical CAD, CAC and aortic-valve calcification in cHypoPT ≥50 years of age was 8.1%, 27.0%, 52.8% and 27.8%, respectively. Frequency of age-adjusted CAC was comparable between cHypoPT and control Group B (30.2% vs. 30.7%, p = .93). Elevated hsCRP was higher in cHypoPT than in controls A (52% vs. 32%, p < .01). Factors associated with CAD in cHypoPT were CAC and hypertension. However, CAD and CAC showed no association with long-term calcemic or phosphatemic control and intracranial-calcification in cHypoPT. CONCLUSIONS: Clinical and subclinical CAD was observed in 3.2% and 12.8% of cHypoPT patients. The increased prevalence of CAD, CAC and aortic-valve calcification in cHypoPT above 50 years of age suggested their careful cardiac evaluation during follow-up.

Awareness and adherence to primary and primordial preventive measures among family members of patients with myocardial infarction-the unmet need for a "Preventive Clinic".

Cardiovascular diseases remain the most common cause of sudden death and cause significant morbidity. We planned this study to assess awareness of cardiovascular risk factors among kin of myocardial infarction patients. We assessed 382 individuals for their knowledge of cardiovascular risk factors. Less than 50% of subjects identified cardiovascular risk factors correctly. Amongst the kins of patients 19.1%, 18.5%, 15.4% were newly diagnosed to have hypertension, impaired fasting blood glucose, diabetes in this study. This study reveals that most of the subjects were unaware of risk factors and were reluctant to adopt a healthy lifestyle. This is a lost opportunity for community-level preventive interventions. There is an unmet need for active health education, follow up with electronic support systems, and a team approach for a model preventive clinic.

Chronic brucellosis with hepatic brucelloma and AA amyloidosis in a patient with autosomal dominant polycystic kidney disease

We describe an autopsy case of a 45-year-old male diagnosed with autosomal dominant polycystic kidney disease who presented with complaints of altered sensorium. The autopsy revealed multiple tumor-like masses in the liver, which on histological examination depicted multiple large suppurative granulomas with the presence of variable acid-fast coccobacilli (consistent with Brucella spp.). Interestingly, extensive amyloid deposition in multiple organs was noted. To the best of our knowledge, this is the first case of chronic brucellosis causing tumor-like abscesses in the liver accompanied by secondary systemic amyloidosis in a patient with underlying autosomal dominant polycystic kidney disease.

Tubercular aortitis presenting as primary aortoenteric fistula: Report of an uncommon case.

Tubercular aortitis presenting as primary aortoenteric fistula (AEF) is a rare entity. We present a 78-year-old male who presented with upper gastrointestinal bleed and also had abdominal pain and pulsating abdominal mass and on evaluation was found to have tubercular AEF which was successfully repaired with surgery and the patient recovered with antitubercular therapy along with the surgery. This case highlights the importance of high index of suspicion with early institution of surgical repair along with antitubercular therapy for tubercular AEF with good results.
