Cord blood cholesterol, triglyceride and FFA levels were estimated in 73 newborns, subdivided into various gestation weight categories (FTAGA, PTAGA, FTSGA and PTSGA). Cholesterol levels were not influenced by birth weight and gestation. Prematurity and growth retardation caused a significant elevation in triglyceride values. FFA levels were not influenced by prematurity, but growth retardation produced a significant increase. Birth weight and gestational age should be taken into consideration before labelling the newborn as hyperlipidemic.

This study was designed to determine whether the National Cholesterol Education Program (NCEP) lipid guidelines accurately identify subclinical atherosclerosis and whether low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels are related to the extent and prematurity of coronary artery disease (CAD) as determined by electron beam tomography (EBT). Out of personal concern for CAD risk, 930 consecutive asymptomatic subjects, without clinical CAD and on no lipid-lowering agents, underwent EBT. Calcium score and percentile were correlated with total cholesterol (TC), LDL-C, HDL-C, triglycerides, and demographic parameters. A calcium score of > 0 (EBT+) was found in 55% of patients; 45% of patients had a 0 score (EBT-). Mean age (58.0 +/- 10.5 vs 49.3 +/- 9.7 years, p = 0.0001), TC (218 +/- 39 vs 211 +/- 41 mg/dl, p = 0.006), LDL-C (136 +/- 36 vs 127 +/- 27 mg/dl, p = 0.005), and TC/HDL-C (4.6 +/- 1.4 vs 4.2 +/- 1.5, p = 0.0001) were significantly higher and HDL-C (52.2 +/- 17.6 vs 55.4 +/- 19.3 mg/dl, p = 0.008) lower in the EBT+ compared with EBT- group. In the EBT+ group, 75.1% of subjects had LDL-C < 160 mg/dl and would not be advised to use lipid-lowering medications according to NCEP guidelines. In subjects with LDL-C < 160 mg/dl, 51.8% of subjects were EBT+, as were 46.1% of those with LDL-C < 100 mg/dl. There were no significant differences in the calcium scores throughout the entire range of all lipid parameters; calcium percentiles were virtually identical within lipid value subgroups. We conclude that asymptomatic patients with EBT-defined subclinical atherosclerosis are not reliably identified by NCEP guidelines, and TC, LDL-C, HDL-C, TC/HDL-C, and triglyceride levels do not correlate with either the extent or prematurity of calcified plaque burden.

Bronchopulmonary dysplasia (BPD) is usually seen in premature infants who require mechanical ventilation and oxygen therapy for acute respiratory distress. Although most patients wean from oxygen therapy by the ages of 2 to 3, rehospitalization for respiratory problems is common in these patients in adulthood. There have been few studies that document the long-term outcomes of BPD survivors and information about the pulmonary function and radiographic findings of adult BPD are limited. Data on pathologic features of adult BPD are scarce. Three adult patients who underwent recent lung transplantation for BPD from 2 institutions were identified. Clinical data including clinical presentation, chest radiographic images, pulmonary function tests, cardiac catheterization, and echocardiography were retrieved from the electronic medical records. Hematoxylin and eosin and selective elastic stained sections of the explant lungs were examined. CD31 immunohistochemical stain is performed on representative sections. All 3 cases had similar clinical and radiologic features including the history of prematurity and long-term mechanical ventilation after birth, hyperexpanded lungs with air trapping and mosaic attenuation on chest computed tomographic scan, severe obstructive changes on pulmonary function test, and pulmonary hypertension. Pathologic examination showed common features including enlarged and simplified alveoli, peribronchial, subpleural, and interlobular septal fibrosis, narrowing/obliteration of the small airways by elastosis and muscular hypertrophy, thickening of venous walls by fibromuscular hyperplasia, and bronchitis/bronchiolitis. Cholesterol granulomas were seen in 2 cases. The common pathologic findings in the lungs explain the clinical and radiologic findings. Future studies are warranted to further characterize the clinical and pathologic features of adult BPD to develop optimal management strategies for these patients.
