[Necrotic myocarditis in acute eosinophilic lymphoblastic leukaemia].

INTRODUCTION: Hypereosinophilia can cause severe cardiac complications. The association between an acute lymphoblastic leukemia and hypereosinophilia was rare. We report a case of a 29-year-old man who presented a heart failure secondary to necrotic myocarditis related to an acute eosinophilic lymphoblastic leukaemia. EXEGESIS: The patient developed a heart failure and secondary a cardio-embolic stroke, due to a large mobile left ventricle thrombosis. His peripheral blood showed a total white count of 28,500 leucocytes/mm3 with 18,800 eosinophils/mm3. The myelogram cytology showed precursor B-cell acute lymphoblastic leukaemia with hypereosinophilia. CONCLUSION: The possibility of the rapid emergence of cardiac lesions in hypereosinophilic syndromes warrants very close physician vigilance. An Echocardiography and MRI performed at the early stage and in the follow-up allow to detect and to manage these cardiac disorders.

[Is pure red cell aplasia a new extra digestive manifestation of celiac disease?].

INTRODUCTION: Celiac disease is an autoimmune enteropathy that appears on a predisposed genetic background. Its clinical presentation has been extended those last years by varied extradigestive manifestations. EXEGESIS: This is a case report of a twenty-year-old woman who presented simultaneously a celiac disease and pure red cell aplasia. The IgA and IgG antigliadin antibodies as well as antinuclear, anti-DNA, anti-SSA and anti-SSB antibodies were detected, without any clinical symptom supporting the diagnosis of systemic lupus erythematosus or Sjögren syndrome. Thoracic CT-scan reveals a thymus enlargement and biopsy concludes to thymus hyperplasia at histological examination. Pure red cell aplasia regressed after gluten-free diet, corticoid therapy and thymectomy. CONCLUSION: This observation, added to the three others paediatric cases previously published in the literature concern an uncommon association between pure red cell aplasia and celiac disease. However, they are not enough to conclude to a direct link between these two disorders. Pure red cell aplasia could represent un new dysimmune manifestation occurring in celiac disease, but this will need to be confirmed with others cases.

[Arterial blood pressure and arterial stiffness in adolescents are related to gestational age].

BACKGROUND: Recent studies show that low birth weight (LBW) infants are at risk of increased arterial blood pressure (BP) in adulthood. Previous work from our centre and others suggests that arterial stiffness (AS) is increased in such patients. However, the respective roles of preterm birth and of intrauterine growth restriction (IUGR) are unclear. AIM: To characterize AS and BP in adolescents who were: born at term with an appropriate birth weight for gestational age (GA) (group 1, n=41); born preterm with an appropriate birth weight for GA (group 2, n=25); born at term and small for GA (group 3, n=24). PATIENTS AND METHODS: Systemic BP was measured with an automated oscillometric device. AS was assessed by measuring pulse wave velocity (PWV) between carotid and radial arteries. RESULTS: 90 adolescents were studied at a mean (SD) age of 13.9 (1.2) years. Subjects from group 2 were born with a 33.6 (1.5) GA. Systolic BP, mean BP, and PWV were significantly increased in group 2 subjects in comparison to both group 1 (123 +/- 11 vs. 117 +/- 11 mmHg, p = 0.04; 88 +/- 7 vs. 83 +/- 7 mmHg, p = 0.03; 7.7 +/- 1.0 vs. 7.0 +/- 0.9 m/s, p = 0.02 respectively) and to group 3 (114 +/- 15 mmHg, p = 0.03: 79 +/- 8 mmHg, p = 0.001; 6.8 +/- 0.9 m/s, p = 0.005 respectively) subjects. Systolic BP, mean BP, and PWV were similar in group 1 and group 3 subjects. CONCLUSION: BP and AS are increased during adolescence in subjects born with a LBW due to preterm birth, while they are not altered in subjects when LBW is related to IUGR. It may be speculated that such changes predispose to long term hypertension and that preterm birth is involved in the early programming of arterial diseases in adulthood.
