Westernization of the Filipino population resident in Rome: obesity, diabetes and hypertension

BACKGROUND: Aims of the present study were to examine the anthropometrical and metabolic characteristics of the Filipino population migrant to the Southern European city of Rome, Italy. METHODS: A cross-sectional study was carried out in the city of Rome. Three hundred thirty-five Filipinos (95 M/240 F, mean age: 44.0+/-9.8 years, mean residence in Italy: 12.9+/-6.3 years) were studied. Data were collected by standardized questionnaires; anthropometrical parameters, arterial pressure, and fasting capillary blood glucose (FCG) were measured. RESULTS: Abdominal obesity was found in 52.5%, and BMI >or= 25 kg/m(2) in 44.5% of subjects. History of type 2 diabetes mellitus (T2DM) and hypertension were reported by 6.0 and 9.0% of subjects, respectively. Impaired fasting glucose was found in 13.1%, and FCG >or= 110 mg/dl in 18.5% of subjects. Altered systolic and/or diastolic blood pressure was found in 34.3% of subjects. About three-fourths of subjects were unaware of being diabetic and/or hypertensive. Years of Italy residence showed a direct significant correlation with the degree of changes in alimentary behaviours (rho=0.18, p=0.001), and with weight gain (rho=0.27, p<0.001). Multivariate analysis showed only age and waist circumference to be associated with both diabetes and hypertension. CONCLUSIONS: In the present study, the first to examine the metabolic disorders in a migrant Filipino population resident in Rome, a high prevalence of obesity, diabetes, and hypertension was found. The alarming results emerging from this study should be seriously considered by public health practitioners and decision makers, and made known to the Filipinos resident in Europe.     

Antiendomysial and antihuman recombinant tissue transglutaminase antibodies in the diagnosis of coeliac disease: a biopsy-proven European multicentre study

OBJECTIVE: To investigate the value of serum antitissue transglutaminase IgA antibodies (IgA-TTG) and IgA antiendomysial antibodies (IgA-EMA) in the diagnosis of coeliac disease in cohorts from different geographical areas in Europe. The setting allowed a further comparison between the antibody results and the conventional small-intestinal histology. METHODS: A total of 144 cases with coeliac disease [median age 19.5 years (range 0.9-81.4)], and 127 disease controls [median age 29.2 years (range 0.5-79.0)], were recruited, on the basis of biopsy, from 13 centres in nine countries. All biopsy specimens were re-evaluated and classified blindly a second time by two investigators. IgA-TTG were determined by ELISA with human recombinant antigen and IgA-EMA by an immunofluorescence test with human umbilical cord as antigen. RESULTS: The quality of the biopsy specimens was not acceptable in 29 (10.7%) of 271 cases and a reliable judgement could not be made, mainly due to poor orientation of the samples. The primary clinical diagnosis and the second classification of the biopsy specimens were divergent in nine cases, and one patient was initially enrolled in the wrong group. Thus, 126 coeliac patients and 106 controls, verified by biopsy, remained for final analysis. The sensitivity of IgA-TTG was 94% and IgA-EMA 89%, the specificity was 99% and 98%, respectively. CONCLUSIONS: Serum IgA-TTG measurement is effective and at least as good as IgA-EMA in the identification of coeliac disease. Due to a high percentage of poor histological specimens, the diagnosis of coeliac disease should not depend only on biopsy, but in addition the clinical picture and serology should be considered.

Favorable toxicity profile of raltitrexed in elderly patients treated for colorectal cancer: a case series

BACKGROUND: Age-related physiological changes may lead to an increased toxicity of chemotherapy in the elderly, thus making tumor treatment difficult in this increasing subset of patients. OBJECTIVE: Since many trials claimed a favorable therapeutic index with raltitrexed, the aim of our preliminary study was to evaluate the anticancer activity and the toxic profile of this drug in the elderly. METHODS: Thirteen elderly patients with colorectal cancer, aged 75-90 years, were enrolled in a monochemotherapy treatment with raltitrexed. Due to their advanced age, the drug was administered with a 33% reduction of the dose. RESULTS: One partial response, four disease stabilizations, and two disease progressions were observed in 7 patients with advanced colorectal cancer. The patients with response or disease stabilisation had a satisfactory time to progression. Four out of 6 patients treated in the adjuvant setting for Dukes' C colorectal cancer remain disease free at observation periods of 15+ to 29+ months. Toxicity was virtually absent in all patients. CONCLUSIONS: The activity of monochemotherapy with raltitrexed appears to be appealing, above all because it is observed in the absence of toxicity. Though recent reports suggest some concern about severe complications of treatment with raltitrexed, administration of reduced doses of this drug seems to be a putative therapy for those patients who, because of their age, are highly susceptible to the adverse effects of chemotherapy.     

Plasma levels of cell adhesion molecules during hyperinsulinemia and modulation of vasoactive mediators

Endothelial expression of cell adhesion molecules (CAMs) plays an important role in atherosclerosis. Atherosclerosis is increased in hyperinsulinemic states, but whether insulin per se is proatherogenic remains unclear. To investigate the effects of hyperinsulinemia on CAM expression, plasma levels of ICAM-1, VCAM-1 and E-selectin were measured before and after forearm infusion of insulin in healthy subjects. Insulin administration for 2h resulted in significant hyperinsulinemia, whereas no significant change was observed in soluble CAMs (all p > 0.05). Because insulin stimulates endothelial release of both endothelin-1 (ET-1) and nitric oxide (NO), which may modulate the expression of CAMs, we also investigated the response of CAMs to ET-1 receptor blockade, alone and in combination with NO synthesis inhibition. ET-1 receptor blockade during hyperinsulinemia resulted in a vasodilator response, but did not affect soluble CAMs (all p > 0.05). Superimposition of NO inhibition by L-NMMA reversed the vasodilator effect of ET-1 blockade, without affecting soluble CAMs (all p > 0.05). In conclusion, acute hyperinsulinemia, alone or during ET-1 and NO pathway blockade, does not affect soluble CAMs. These results do not support a direct effect of insulin on endothelial cells to affect leukocyte adhesiveness to the vascular wall.     

Primary cardiac T-cell lymphoma

Primary cardiac lymphoma (PCL), defined as a lymphoma clinically mimicking cardiac disease, with the bulk of the tumor located intrapericardially, is extremely rare in immunocompetent patients. Clinical manifestations vary depending on sites of involvement in the heart and include chest pain, arrhythmias, pericardial effusion, and heart failure. Diagnosis is often difficult and may require invasive procedures; in some cases, diagnosis is not made until autopsy. Histologically, nearly all cases of PCL reported thus far have been of B-cell origin. In this report, we describe a case of PCL of T-cell origin in an adult immunocompetent patient, the second reported in the literature to the best of our knowledge, and provide a brief overview of the features of previously published PCL cases.     

Bcl-6 gene mutations in primary cutaneous B-cell lymphomas

We analyzed mutations in the 5' non-coding region of the BCL-6 gene in 46 cases of primary cutaneous B-cell lymphomas (PCBCL), using a polymerase chain reaction single strand conformation polymorphism (PCR-SSCP) method. The results indicate that PCBCL display a low frequency of mutations and support a marginal zone B-cell origin for most of these neoplasms.     

Investigational therapies currently in Phase II clinical trials for the treatment of pelvic serous carcinomas

Introduction: Pelvic serous carcinomas (PSCs) are a controversial entity, which mostly comprise fallopian tube carcinoma (FTC), primary peritoneal carcinoma (PPC) and serous ovarian carcinoma (OC). Despite incremental attention towards understanding pelvic serous carcinogenesis, the gold standard treatment and survival rates have not substantially changed in these last decades.

Areas covered: This review summarizes and gives a critical overview of the ongoing Phase II trials investigating therapies for PSC.

Expert opinion: Several novel molecules have been developed and are currently under investigation for the treatment of PSC, including FTC, PPC and serous OC. The trend of novel targeted agents is one towards individualized, tailored therapy, based on the molecular and biological differences that characterize tumors that seem similar based solely on histological analysis. The task of developing new molecules is particularly difficult for PSC, given the recurrent development of new patterns of drug resistance. However, even if current research is focused towards identifying the best treatments for each woman with a molecularly defined disease, a deeper knowledge of the molecular biology and genetics underlying FTC and its relation as a precursor of PSC is needed.     

Plasmodium falciparum chloroquine and quinine sensitivity in asymptomatic and symptomatic children in São Tomé Island

Plasmodium falciparum sensitivity to quinine in São Tomé was determined by in vivo and in vitro tests in 56 children with mild or cerebral malaria. Chloroquine sensitivity was assessed by in vitro tests in 105 parasitaemic asymptomatic children from the same community as the cases. The WHO standard methodology was used. No resistance to quinine was found by in vivo or in vitro tests in either group of patients or in asymptomatic children, although some degree of chloroquine resistance was found with the in vitro test. This was more common in patients than in asymptomatic children. Chloroquine resistance may be explained by the recent history of malaria in São Tomé Island, which caused an important decrease of immunity among the population and consequently the emergence of resistant strains. Implications of the use of in vivo / in vitro tests for determining the antimalarial drug policy within the primary health care system are discussed.
