The Case | Ectopic calcifications in a child

The case A nine year old boy, born of third degree consanguinity, presented with a hard left scapular swelling for 6 months. There was no history of fever, trauma or weight loss. There was no pain, redness or discharge. This mass was excised but recurred over the next 6 months (Left panel of Figure 1). A similar swelling had been excised from the left knee one year before presentation, but had recurred over 6 months. Family history was negative for similar lesions. Development was normal for age and he had no other medical problems. On examination, pulse was 84 per minute, blood pressure 96/68 mmHg, weight 22 kg and height 122 cm (both between 10th and 25th percentile). A 6 × 4 cm mass was noted in the right scapular region and a 3 × 3 cm mass at the lateral aspect of the left knee. Both of these masses were firm to hard, globular, nontender, and fixed to the bone. The overlying skin was without erythema or local warmth, though scars from the previous resections were noted. Lymphadenopathy was absent. The rest of the examination was unremarkable. Radiographs of the knee showed a lobular, inhomogenously but densely calcified lesion in the anterolateral region of the left knee (Right panel of Figure 1). Serum calcium was 9.

Cardiovascular complications in kidney transplant recipients with COVID-19: A case series

Kidney transplant recipients (KTRs) are at a higher risk for developing severe COVID-19 which can be associated with cardiovascular complications. We studied five KTRs recipients infected with COVID-19 who developed severe cardiovascular complications. Two patients presented with ST segment myocardial infarction and two with clinically suspected myocarditis. One patient presented with atrial fibrillation. Two of these patients developed cardiogenic shock. Inflammatory markers were at peak during the event in four of these who had presented with severe COVID-19. Coronary angiography done in two patients with STEMI did not reveal any evidence of atherosclerotic coronary artery disease. Also, based on the cardiovascular (CV) risk estimation by Framingham score, four patients had low CV risk and one patient had intermediate CV risk. All five patients survived. Even with low CV risk, KTRs can develop myocardial injury and arrhythmias solely because of severe COVID-19

Clinical course and outcomes of COVID-19 in kidney transplant recipients

Introduction: Kidney transplant recipients (KTR) are at increased risk of morbidity and mortality due to coronavirus disease 2019 (COVID-19). This study aimed to explore the clinical characteristics and outcomes of COVID-19 in KTR. Methods: We reviewed the clinical profile, outcomes, and immunological responses of recipients admitted with COVID-19. We determined the risk factors for mortality and severe COVID-19. Results: Out of 452 recipients on follow-up, 60 were admitted with COVID-19. Prevalent comorbidities were hypertension (71%), diabetes (40%), lung disease (17%). About 27% had tuberculosis. The median Sequential Organ Failure Assessment score at presentation was 3 (interquartile range [IQR] 1–5). There was a high incidence of diarrhea (52%) and anemia (82%). Treatment strategies included antimetabolite withdrawal (85%), calcineurin inhibitor decrease or withdrawal (64%), increased steroids (53%), hydroxychloroquine (21%), remdesivir (28.3%), and tocilizumab (3.3%). Severe COVID-19 occurred in 34 (56.4%) patients. During a median follow-up of 42.5 days (IQR 21–81 days), 83% developed acute kidney injury (AKI) and eight (13%) died. Mortality was associated with the baseline graft dysfunction, hypoxia at admission, lower hemoglobin and platelets, higher transaminases, higher C reactive protein, diffuse radiological lung involvement, hypotension requiring inotropes, and Kidney Diseases Improving Global Outcomes (KDIGO) stage 3 AKI (univariate analysis). Around 57% of patients remained RT-PCR positive at the time of discharge. By the last follow-up, 66.6% of patients developed IgM (immunoglobulin M) antibodies and 82.3% of patients developed IgG antibodies. Conclusion: COVID-19 in kidney transplant recipients is associated with a high risk of AKI and significant mortality
