ABSTRACT
Introduction: Protein energy wasting (PEW) is an established entity in adults with CKD but is not well studied in children. The burden of PEW has been observed to be higher in Indian children with CKD compared to the chronic kidney disease in children (CKiD) cohort. The impact of PEW on outcomes needs to be addressed in these children with CKD. This prospective longitudinal study was undertaken in children with CKD 2-5D to assess the association of PEW with clinical outcomes of infection related hospital admissions (IRHA). Method(s): Children (age 2-18 years) with CKD 2-5D, from a tertiary care center were recruited for PEW assessment from January 2017 following ethical committee approval and informed consent. Children with evidence of infection in the last month and those on dialysis for less than a month were excluded. Demographic characteristics and clinical outcomes of hospital admissions were recorded till June 2022. Based on the CKiD study, PEW was diagnosed and categorized using 5 criteria: 1. Muscle mass (Mid arm muscle circumference);2. Body mass (body mass index);3. Biochemical parameters (serum cholesterol, serum albumin, serum transferrin, and C-reactive protein);4: Appetite and 5. Short stature. PEW was further categorized as mild (> 2 criteria), standard (> 3 criteria), and modified (> 3 criteria with short stature). Infections that needed hospitalization included viral hemorrhagic fever, COVID-19 infection, sepsis, urinary tract infection, lower respiratory tract infection, peritonitis, and catheter-related blood stream infection. Result(s): Among 136 children (45 on dialysis, mean age 122 + 46 months, 70% males) 72 (53%) had PEW. The proportions of those with mild, standard, and modified PEW were 8%, 13%, and 32% respectively. Over a mean follow-up of 38 + 21 months, 104 (76%) children required hospital admissions of which 69% were due to infections. Death was noted in 2%, and 12% got transplanted. The proportion of children needing hospital admissions was significantly higher in those with PEW compared to those without PEW (85% vs 66% respectively, p=0.011). IRHA was observed in 68% of children with PEW compared to 36% without PEW (p<0.001). The proportion of IRHA in those with dialysis with or without PEW ((87% vs 50%, p=0.001) was significantly higher compared to those with CKD 2-5 (54% vs 32%, p= 0.03). In the overall cohort, the proportion of IRHA was significantly higher with modified PEW compared to other PEW categories (p<0.001), [modified: 74.4%, standard: 58.0%, mild: 59%, no PEW: 36%]. On multivariable analysis, by adjusting for age, gender, etiology of CKD, and dialysis, the presence of PEW and dialysis status were independent factors associated with IRHA [Adjusted OR 3.58 (1.62,7.89), p=0.002] and [OR 3.29 (1.4,7.75), p=0.006, respectively]. Similarly, the presence of inflammation was independently associated with IRHA [OR 3.93 (1.49, 10.3), p=0.002]. Figure 1 shows the risk factors associated with IRHA based on PEW categories and inflammation status. [Formula presented] Conclusion(s): In children with CKD 2-5D, the presence of PEW and inflammation were significantly associated with IRHA. Children with modified PEW had nearly 5 times more risk of developing IRHA, reinforcing the importance of growth as a unique parameter of PEW in these children.

ABSTRACT
Purpose Characteristics and outcomes of heart transplant (HT) recipients who contract coronavirus (SARS-CoV-2) have been poorly described. The current study was undertaken to better understand the risk obesity may pose in this patient population Methods A prospectively-maintained Trans-CoV-VAD Registry containing HT recipients at 11 participating institutions who presented with SARS-CoV-2 were reviewed. Presenting characteristics, hospitalization rates, ventilator & intensive care unit usage, and mortality were queried. Patients were grouped by body mass index (BMI) into obese (BMI≥30 k/m2) and non-obese cohorts (BMI<30 kg/m2). Comparisons between groups were made utilizing chi-squared, Fisher's exact, and Mann-Whitney U-tests. Multivariable logistic regression models were utilized Results Across all centers, 85 HT recipients who tested positive for SARS-CoV-2 were identified, of whom 26 (31%) were obese. Median time from HT to diagnosis was 4.6 (1.8-13.8) years. No differences in age (57 vs 60 p 0.85) or female gender (31% vs 24% p 0.5) were noted between obese and non-obese patients. On presentation, obese patients were more symptomatic with higher rates of cough (76% vs 48% p 0.02), dyspnea (62% vs 41% p 0.09), diarrhea (60% vs 35% p 0.03), and headache (35% vs 14% p 0.03). No differences in rates of admission (62% vs 64% p 0.8), ICU presentation (44% vs 35% p 0.6) or need for mechanical ventilation were noted (38% vs 22% p 0.2). More secondary infections were noted amongst obese patients (32% vs 13% p 0.04). On follow-up, mortality was similar between groups (12% vs 9% p 0.7). On multivariable modeling, BMI was not associated with increased adjusted odds of hospital/ICU admission or mechanical ventilation (p>0.10) Conclusion Acute presentations of SARS-CoV-2 amongst HT recipients carry significantly higher mortality over the general population. Obesity appears to impact presenting symptoms and secondary infections, but does not strongly impact ICU requirements or mortality
ABSTRACT
Purpose Infection with the Coronavirus (SARS-CoV-2) is particularly dangerous for patients with left ventricular assist devices (LVAD). Obesity is associated with worse outcomes among both LVAD and SARS-CoV-2 patients. This study evaluated the risk of obesity among LVAD patients who contracted SARS-CoV-2. Methods A prospectively maintained Trans-CoV-VAD Registry of LVAD patients from 11 institutions who presented with SARS-CoV-2 was analyzed. Two cohorts, 1) non-obese and 2) obese, were formed utilizing a body mass index (BMI) cutoff of 30 k/m2. Presenting characteristics, hospitalization rates, ventilator & intensive care unit usage, and mortality were compared. Chi-squared, Fisher's exact test, Mann-Whitney U-tests and multivariable logistic regression models were utilized. Results Across all centers, 46 LVAD patients contracted SARS-CoV-2 during the study period of whom 19 (41%) were obese. Time from LVAD implantation to infection was 2.4±2.5 years. Age and gender profiles were similar. Non-obese and obese patients had similar presenting symptoms, most commonly cough (52% vs 47%), fever (48% vs 37%), dyspnea (41% vs 47%) and fatigue (41% vs 37%). No difference in rates of hospital (70% vs 63%, p 0.8) and ICU admissions (26% vs 37%, p 0.3) was observed. Hospital (20.0±23.2 vs 17.1±14.2) and ICU length of stay were similar (16.2±26.1 vs. 13.9±13.1 days). Obese patients were more likely to require mechanical ventilation than non-obese patients (7% vs 26%, p<0.05). Overall risk of mortality was significantly elevated but similar (19% vs 16%, p 0.9). On multivariable modeling, BMI was not associated with increased risk of hospitalization, ICU admission or mechanical ventilation (p>0.10). Conclusion Among LVAD patients who contract SARS-CoV-2, obese patients appear to have higher risk of intubation, but did not experience increased ICU requirements or mortality.
