Echocardiographic changes in anorexia nervosa: a pathophysiological adaptation or a disease?

Anorexia Nervosa is one of the most common form of eating disorders. Cardiac involvement occurs in approximately 80% of patients. Few reports focused on the association between body weight fluctuations and echocardiographic abnormalities, considering linear measurements. We describe echocardiographic and clinical features among male and female patients with anorexia nervosa and the effect of weight gain on these parameters. We performed a single center, retrospective study of patients followed at a dedicated multidisciplinary Unit. The study population consisted of 81 patients, mean age 25 ± 11 years, 94% female. Median body mass index was 14.4 kg/m2 (25th-75th percentile 12.7-15.6 kg/m2). Patients with body mass index below the median value had more often pericardial effusion, smaller left ventricular mass and left ventricular end-diastolic volume and thinner interventricular septum. However, when indexed to body surface area, left ventricular mass and volumes were within the normal range in 90% of population. Patients with pericardial effusion showed mitral valve abnormalities and lower values of white blood cells and platelets, although within normal limits. Presence of pericardial effusion was not related to inflammatory parameters or low plasma protein levels. In 39 patients who displayed weight gain during a median follow-up of 189 days (25th-75th percentile 47-471), increased left ventricular mass, interventricular septum thickness, white blood cells and platelet count and decreased pericardial effusion were observed. Patients with anorexia nervosa have a specific echocardiographic pattern which seems to be proportional to the body size, suggesting a pathophysiological adaptation to the lack of substrates.

[Pulmonary hypertension in autoimmune rheumatic diseases]. / L'ipertensione polmonare nelle malattie reumatiche autoimmuni.

OBJECTIVE: Pulmonary hypertension is a severe and rapidly progressive disease, particularly frequent in patients with rheumatic diseases. The aims of this study were the following: to determine the prevalence of pulmonary hypertension in Italian patients with autoimmune rheumatic diseases, and to evaluate if the presence of a rheumatic disease in general, or of a specific autoimmune rheumatic disease, is a risk factor for the development of pulmonary hypertension. PATIENTS AND METHODS: One hundred and thirteen Italian patients with connective tissue diseases (105 females, 8 males), aged 19 to 83 yrs, entered the study. Fifty-one had systemic sclerosis (SSc): 49 were females, 2 males, aged 34 to 83 yrs; 41 had limited cutaneous SSc, 8 diffuse cutaneous SSc, and 2 SSc sine scleroderma. Thirty-three patients had systemic lupus erythematosus (SLE): all but one were females, their age ranged from 19 to 82 yrs. Twenty-five had rheumatoid arthritis (RA): 21 females, 4 males, aged 26 to 45 yrs. Three females and one male, 51-77 yrs, had mixed connective tissue disease (MCTD). Systolic pulmonary arterial pressure (SPAP) was assessed by Doppler echocardiography. RESULTS: Twenty three patients had pulmonary hypertension, which was more frequent in MCTD than in SLE (75% vs 6.1%, p=0.0002) or in AR (20%, p=0.0313). Pulmonary hypertension was more frequent in SSc than in SLE (25.5% vs 6.1%, p=0.0028) and in limited than in diffuse SSc (21.6% vs 3.9%). SPAP was significantly related to age (r=0.35, p=0.0275), with patients with pulmonary hypertension older than patients with normal SPAP (66+/-13 vs 52+/-16 yrs, p=0.0003). CONCLUSIONS: These data show a significant association between pulmonary hypertension and autoimmune rheumatic diseases. Therefore, pulmonary hypertension assessment seems mandatory, at least in MCTD and SSc. However, more studies are needed to clarify the relationship between age and pulmonary hypertension and to verify whether the low prevalence of pulmonary hypertension we found in our SLE patients is related or not to their lower age.

Carcinoid heart disease from ovarian primary presenting with acute pericarditis and biventricular failure.

A case is described of a 54 year old woman who had acute pericarditis with large exudative effusion accompanied by severe right and left ventricular failure. The patient was finally diagnosed with carcinoid heart disease from an ovarian carcinoid teratoma. She was treated with octreotide--a somatostatin analogue--followed by radical surgical resection of the neoplasm. At one year follow up only mild carcinoid tricuspid regurgitation remained. Only 16 cases of carcinoid heart disease from an ovarian primary have been described in literature. Moreover clinically manifest acute, nonmetastatic pericarditis and left heart failure are not considered as possible presentations of carcinoid heart disease, whatever the origin. In a recent series a small pericardial effusion was considered an infrequent and unexpected echocardiographic finding in carcinoid heart patients. One case of "carcinoid pericarditis" has previously been described as a consequence of pericardial metastasis. Left sided heart involvement is usually caused by bronchial carcinoids or patency of foramen ovale; both were excluded in the case presented.
