RESUMO

The use of chest computed tomography (CT) as an imaging test for the evaluation of thoracic pathology has significantly increased during the last four decades. Although cardiopulmonary diseases often overlap in their clinical manifestation, radiologists tend to overlook the heart while interpreting routine chest CT. Recent advances in CT technology have led to significant reduction of heart motion artefacts and now allow for the identification of several cardiac findings on chest CT even without electrocardiogram (ECG) gating. These observations range from simple curiosity to both benign and malignant discoveries, to life-threatening discoveries. We here present a clinical and radiologic review of common and less common cardiac findings discovered on non-gated chest CT in order to draw the attention of radiologists and referring physicians to these possibilities.

RESUMO

BACKGROUND: Imatinib (400 mg daily) is considered the best initial therapy for patients with newly diagnosed chronic myeloid leukemia (CML) in the chronic phase. However, only a minority of patients treated with imatinib have a complete molecular remission. METHODS: We randomly assigned 636 patients with untreated chronic-phase CML to receive imatinib alone at a dose of 400 mg daily, imatinib (400 mg daily) plus cytarabine (20 mg per square meter of body-surface area per day on days 15 through 28 of each 28-day cycle) or pegylated interferon (peginterferon) alfa-2a (90 µg weekly), or imatinib alone at a dose of 600 mg daily. Molecular and cytogenetic responses, time to treatment failure, overall and event-free survival, and adverse events were assessed. An analysis of molecular response at 12 months was planned. A superior molecular response was defined as a decrease in the ratio of transcripts of the tyrosine kinase gene BCR-ABL to transcripts of ABL of 0.01% or less, corresponding to a reduction of 4 log(10) units or more from the baseline level, as assessed by means of a real-time quantitative polymerase-chain-reaction assay. RESULTS: At 12 months, the rates of cytogenetic response were similar among the four groups. The rate of a superior molecular response was significantly higher among patients receiving imatinib and peginterferon alfa-2a (30%) than among patients receiving 400 mg of imatinib alone (14%) (P=0.001). The rate was significantly higher among patients treated for more than 12 months than among those treated for 12 months or less. Gastrointestinal events were more frequent among patients receiving cytarabine, whereas rash and depression were more frequent among patients receiving peginterferon alfa-2a. CONCLUSIONS: As compared with other treatments, the addition of peginterferon alfa-2a to imatinib therapy resulted in significantly higher rates of molecular response in patients with chronic-phase CML.

RESUMO

PURPOSE First-line treatment for patients with newly diagnosed follicular lymphoma (FL) still remains debated, even in the rituximab-based combination therapy era. Few studies have addressed the question whether complete remission (CR) translates into better survival. The aim of this study was to assess the long-term follow-up of prospectively treated patients with FL and the potential correlation between response quality to first-line treatment and overall survival (OS). PATIENTS AND METHODS Data from 536 patients with FL with low (n = 193) or high (n = 343) tumor burden enrolled from October 1986 to May 1995 in the French and Belgian GELF86 studies were analyzed. Data from these trials have been previously reported for low-tumor burden and high-tumor burden patients. Results Median follow-up was 14.9 years, and median OS was 9.8 years. Treated patients who achieved a complete response (CR; n = 194; 45%) had a significant longer OS than those only reaching a partial response (PR; n = 168; 39%) throughout treatment (hazard ratio [HR], 0.55; 95% CI, 0.42 to 0.72; P < .001) in an univariate time-dependent Cox model. Similar findings were found when response to treatment (CR v PR) was adjusted for potentially confounding factors in a multivariate model (HR, 0.53; 95% CI, 0.38 to 0.73; P < .001). CONCLUSION These data provide a long follow-up of these patients' cohorts and indicate that a better response to first-line treatment translates into an improved survival for patients with FL. Therefore, response-adapted therapy aiming to achieve a CR should be considered as first-line treatment.

RESUMO

BACKGROUND AND OBJECTIVES: In non-randomized studies, thalidomide appeared to be effective in myeloid metaplasia with myelofibrosis (MMM). We compared thalidomide to placebo for treatment of anemia in MMM. DESIGN AND METHODS: A prospective phase II B, randomized double-blind multicenter trial comparing thalidomide 400 mg/d with placebo for 180 days was conducted in 52 anemic patients (hemoglobin pounds Sterling 9 g/dL or transfused). The main outcome measure was a 2 g/L increase in hemoglobin or 20% reduction in transfusions. RESULTS: In the thalidomide group only 10 patients completed 6 months of treatment. At 180 days, in an intention-to-treat analysis, no difference was observed between the thalidomide and placebo groups as regards improvement of hemoglobin levels (one patient in each group) or reduction of red blood cell transfusions (three vs five patients, respectively). The spleen size, determined by ultrasonography, increased significantly less in the thalidomide group than in the placebo group (p < 0.05). Thalidomide had no apparent benefit on the Dupriez score, the severity score, survival, death, or any other clinical or biological parameter. Somnolence, gastro-intestinal signs, weight gain, and edema were significantly more frequent in the thalidomide group. Outpatient discontinuation of thalidomide was significantly correlated with a high severity score > 4 (odds ratio, OR = 16; p < 0.01), and g-glutamyl transferase levels > 40 IU/L (OR = 12; p < 0.05). INTERPRETATION AND CONCLUSIONS: Thalidomide (200-400 mg/d) does not demonstrate substantial efficacy in anemic MMM patients. The natural history of disease in the placebo group revealed spontaneous periods of remission of anemia. Tolerance of thalidomide was significantly correlated wih the severity and liver involvement of the disease.

RESUMO

BACKGROUND: Efavirenz (EFV) is a highly active antiretroviral drug, use of which is associated with frequent (although transient) neurosensorial adverse reactions. Whether the use of EFV is associated with the risk of depression or suicide remains controversial. METHODS: ALIZE-ANRS (Agence Nationale de Recherches sur le SIDA et les Hepatites Virales) 099 was a 48-week randomized trial involving virologically suppressed, human immunodeficiency virus (HIV)-infected patients that compared the maintenance of a treatment regimen that contained protease inhibitors (177 subjects) with a switch to a once-daily combination of EFV, didanosine, and emtricitabine (178 subjects). We used the trial's adverse events reporting system and a self-administered Center for Epidemiologic Studies-Depression Scale questionnaire to assess depressive disorders. Determinants were studied using a multivariate proportional hazards model adjusted for antiretroviral treatment, sex, age, HIV risk factor, history of depression, hepatic disorder, alcohol abuse, and HIV-related or non-HIV-related events. RESULTS: Thirty cases of depressive disorder (26 cases of depression and 4 suicide attempts) occurred during treatment in 27 patients (12 patients [7%] and 15 patients [8%] in the protease inhibitor-based and EFV-based treatment arms, respectively; P = .56). In the proportional hazards model, only age (hazard ratio, 1.6 per 10 years younger; 95% confidence interval, 1.0-2.6) and a history of depressive disorder (hazard ratio, 5.0; 95% confidence interval, 2.1-12.0) were associated with a risk of depressive disorders. The proportion of depressive patients (24%), as determined on the basis of the Center for Epidemiologic Studies-Depression Scale data, was stable during the follow-up period, without difference between treatment groups. Patients with a history of depressive disorder were more frequently depressed (53%) than were those without such history (22%; P = .03). CONCLUSIONS: The frequency of depressive disorders was high in this population, but the disorders were not related to EFV treatment. Younger age and a history of depression are important determinants for depression and should be considered for early detection and case management.

RESUMO

The incidence of hepatic adverse drug reactions (ADRs) remains unknown in the general population. The goal of this population-based study was to assess the incidence and seriousness of hepatic ADRs. All new cases of symptomatic drug-induced hepatic injuries were collected by 139 trained physicians (general practitioners [GPs] and specialists) between November 1997 and November 2000 in an area containing 81,301 inhabitants who could not go elsewhere for medical care. Over 3 years, 34 cases of hepatic ADRs were collected, 82% of them in outpatients. Global crude annual incidence rate was 13.9 +/- 2.4 per 100,000 inhabitants; corresponding standardized annual global rate was 8.1 +/- 1.5. There was no difference between urban and rural areas. Standardized incidence female/male ratio was 0.86 (0.26-2.90) until 49 years of age and 2.62 (1.00-6.92) after this age. Diagnosis was carried out by GPs in half of the cases. The outcome was recovery for 32 patients and death for 2. The main drugs implicated were anti-infectious, psychotropic, hypolipidemic agents, and nonsteroidal anti-inflammatory drugs (NSAIDs). Our results suggest that the number of hepatic ADRs in the French population would be 16 times greater than the number noted by spontaneous reporting to French regulatory authorities. In conclusion, the incidence and seriousness of drug-induced hepatitis are largely underestimated in the general population. These results may be useful for further evaluation of drug-induced hepatotoxicity.
