Amyloid goiter in Familial Mediterranean Fever (FMF): a clinicopathologic study of 10 cases.

FMF Amyloidosis is an important etiological factor of end stage renal disease (ESRD) in Mediterranean Countries. Apart from major target organs as cardiovascular, respiratory and gastrointestinal system, endocrine organs can also be involved. We planned to investigate the thyroid involvement in our amyloidosis group. The aim of this study was to determine clinical characteristics of amyloid goiter in FMF patients and the abnormalities of thyroid function, as well as to identify pathologic characteristics. Twenty-two hemodialysis patients (mean age 34.1 +/- 14 years, range 17-68) whose ESRD secondary to FMF amyloidosis were evaluated with physical examination, serum levels of thyroid hormones, ultrasound examination of thyroid glands, thyroid syntigraphic studies. Goiter was found in 10 patients (4 male, 6 female) having enlarged neck mass (mean age 35 +/- 14 years, range 23-64). The serum levels of thyroid hormones and TSH were normal in 4 patients. Other four cases had euthyroid sick syndrome. Only one patient developed tender enlarged neck mass with subacute thyroiditis symptoms and one had primary hyperthyroidism. Ultrasound examination showed; hypoecoic nodules in 6 patients diffuse multinodular enlargement in 4 patients. Thyroid syntigraphic studies revealed hypoactive nodules in 7 patients and hyperactive nodules in 3 patients. After the laboratory tests were completed, in 10 patients diagnosis were made with fine needle aspiration biopsy. Of 10 patients 5 underwent subtotal thyroidectomy. Immunohistochemical evaluation demonstrated the presence of amyloid AA immunoreactivity in all cases. In conclusion fine needle aspiration from the thyroid when enlarged is useful in the diagnosis of suspected amyloidosis, especially since it is a safe, easily performed procedure. With the help of amyloid goiter diagnosis the patient's prognosis on hemodialysis and with renal transplantation can be predicted. Amyloid goiter must be searched in hemodialysis patients especially in Mediterranean Countries.

Intake of fatty acids in western Europe with emphasis on trans fatty acids: the TRANSFAIR Study.

OBJECTIVE: To assess the intake of trans fatty acids (TFA) and other fatty acids in 14 Western European countries. DESIGN AND SUBJECTS: A maximum of 100 foods per country were sampled and centrally analysed. Each country calculated the intake of individual trans and other fatty acids, clusters of fatty acids and total fat in adults and/or the total population using the best available national food consumption data set. RESULTS: A wide variation was observed in the intake of total fat and (clusters) of fatty acids in absolute amounts. The variation in proportion of energy derived from total fat and from clusters of fatty acids was less. Only in Finland, Italy, Norway and Portugal total fat did provide on average less than 35% of energy intake. Saturated fatty acids (SFA) provided on average between 10% and 19% of total energy intake, with the lowest contribution in most Mediterranean countries. TFA intake ranged from 0.5% (Greece, Italy) to 2.1% (Iceland) of energy intake among men and from 0.8% (Greece) to 1.9% among women (Iceland) (1.2-6.7 g/d and 1.7-4.1 g/d, respectively). The TFA intake was lowest in Mediterranean countries (0.5-0.8 en%) but was also below 1% of energy in Finland and Germany. Moderate intakes were seen in Belgium, The Netherlands, Norway and UK and highest intake in Iceland. Trans isomers of C18:1 were the most TFA in the diet. Monounsaturated fatty acids contributed 9-12% of mean daily energy intake (except for Greece, nearly 18%) and polyunsaturated fatty acids 3-7%. CONCLUSION: The current intake of TFA in most Western European countries does not appear to be a reason for major concern. In several countries a considerable proportion of energy was derived from SFA. It would therefore be prudent to reduce intake of all cholesterol-raising fatty acids, TFA included.

Health implications of Mediterranean diets in light of contemporary knowledge. 1. Plant foods and dairy products.

Several carefully studied populations in Mediterranean countries and in some areas in Asia where traditional diets consisted largely of foods of plant origin exhibit low rates of many chronic diseases and long life expectancies. Many case-control and prospective studies have provided further evidence that high consumption of plant foods confers numerous health benefits. Investigations support links between increased vegetable, fruit, and fiber consumption, and lower rates of several cancers, coronary heart disease (CHD), neural tube defects, and cataracts. Although the mechanisms are not fully understood, carotenoids, folic acid, and fiber, all abundant in the Mediterranean diet, appear to play important roles in prevention of these diseases. In contrast, much evidence suggests that high consumption of full-fat dairy products is likely to increase CHD risk. Epidemiologic studies have not provided evidence that high dairy product consumption by adults prevents fractures; in fact, the results of several studies suggest positive associations. Thus, the abundant fruit, vegetables, and whole grains, and the low to moderate intake of dairy products in traditional Mediterranean diets are likely to have contributed to the low rates of numerous chronic diseases observed in these populations.

Epidemiology and pathogenesis of Kaposi's sarcoma-associated herpesvirus.

Kaposi's sarcoma (KS) occurs in Europe and the Mediterranean countries (classic KS) and Africa (endemic KS), immunosuppressed patients (iatrogenic or post-transplant KS) and those with acquired immune deficiency syndrome (AIDS), especially among those who acquired human immunodeficiency virus sexually (AIDS-KS). KS-associated herpesvirus (KSHV or HHV-8) is unusual among herpesviruses in having a restricted geographical distribution. Like KS, which it induces in immunosuppressed or elderly people, the virus is prevalent in Africa, in Mediterranean countries, among Jews and Arabs and certain Amerindians. Distinct KSHV genotypes occur in different parts of the world, but have not been identified as having a differential pathogenesis. KSHV is aetiologically linked to three distinct neoplasms: (i) KS, (ii) primary effusion lymphoma, and (iii) plasmablastic multicentric Castleman's disease. The histogenesis, clonality and pathology of the tumours are described, together with the epidemiology and possible modes of transmission of the virus.

Epidemiological evidence for the non-random clustering of the components of the metabolic syndrome: multicentre study of the Mediterranean Group for the Study of Diabetes.

OBJECTIVE: To determine: (a) whether the components of metabolic syndrome (MetS) cluster more frequently than predicted by chance alone and (b) whether increased risk for MetS is associated also with values of each component below, but close to the cutoff points defining MetS. RESEARCH DESIGN AND METHODS: Anthropometrical and biochemical measurements were performed and a dietary questionnaire was filled-in in 1833 randomly selected non-diabetic subjects, 916 men and 917 women, 20-74 years old, in nine centres in five Mediterranean countries. The prevalence of MetS and of possible combinations of its individual components was measured. The expected frequencies of the above combinations were calculated according to the mathematical formula of probabilities. RESULTS: The overall prevalence of MetS was 27.2%, but varied greatly among countries, from 5.8% in Algeria to 37.3% in Greece. The observed prevalence of each combination diagnostic of MetS was higher than the expected by chance. Thus, the observed overall prevalence of MetS was also higher than the expected, 27.2 vs 24.0%, P=0.03. Furthermore, for each individual component (except high-density lipoprotein), as values in the normal range, approached the cutoff point, the risk of having MetS (i.e. clustering of the other components) increased significantly (odds ratio 2.2-4.6, P<0.001). CONCLUSIONS: The MetS is not related to the Mediterranean type of diet and its prevalence varies greatly among five Mediterranean countries. The clustering of the components defining the MetS is not due to chance and moreover even 'high normal' levels of each component confer increased risk for the syndrome.

Spectrum of phenylketonuria mutations in western Europe and north Africa, and their relation to polymorphic DNA haplotypes at the phenylalanine hydroxylase locus.

A total of 252 chromosomes from 126 patients with phenylalanine hydroxylase (PAH) deficiencies were analyzed for both mutant genotypes and restriction fragment length polymorphism (RFLP) haplotypes at the PAH locus. The mutant genes studied originated either from Western Europe (116 alleles) or from Mediterranean countries (136 alleles). Only 27% of all mutant alleles were found to carry identified mutations, particularly mutations at codon 252 (2.3%), 261 (7.5%), 280 (6.3%), 408 (3.5%) and at the splice donor site of intron 12 (6.3%). The mutant genotypes were associated with RFLP haplotypes 7, 1, 38, 2 and 3 at the PAH locus respectively. Except for the splice mutation of intron 12, these associations were preferential, but not exclusive, since the other four mutations were found on the background of at least two RFLP haplotypes. These results, together with the observation that 85% of PAH deficient patients are heterozygotes for their mutant genotypes, emphasize the great heterogeneity of PAH deficiencies in Mediterranean countries and hamper systematic DNA testing for carrier status in this population.

Low calcium and vitamin D intake in healthy children and adolescents and their correlates.

BACKGROUND: Optimal dietary calcium and possibly vitamin D intake throughout childhood and adolescence may enhance bone mineral accrual. Little data on the intake of these nutrients in Mediterranean countries exist, and predictors of their suboptimal intake are not well defined. OBJECTIVE: To evaluate systematically the effect of gender, lifestyle factors, and socioeconomic status on mean calcium and vitamin D intake in healthy school children and adolescents from Lebanon. DESIGN: A total of 385 students aged 10-16 y were selected from four public and four private schools between Fall 1999 and Spring 2000. Information on calcium and vitamin D intake, through a semiquantitative food frequency questionnaire that was validated against a 7-day daily record, and on socioeconomic and lifestyle factors were obtained. RESULTS: Only 12% of the students met the adequate intake (AI) recommendation of 1300 mg of calcium/day, and only 16% met the AI recommendation of 200 IU of vitamin D/day. Boys had a significantly higher mean daily calcium intake than girls. Socioeconomic status as assessed by children's pocket money was a predictor of higher calcium and vitamin D intake. Eating breakfast and physical activity were other correlates of daily calcium and vitamin D intake. CONCLUSIONS: Only a minority of students in our study met the AI for calcium and vitamin D. Gender, lifestyle factors, and socioeconomic status were significant predictors of calcium and vitamin D intake. Our findings have important implications regarding the institution of dietary public health strategies to promote skeletal health in Mediterranean countries during a critical time for bone mass accrual.

[Ophthalmomyiasis externa acquired in Germany: case report and review of the literature].

UNLABELLED: Infestation with larvae (maggots) is known as myiasis. Ophthalmomyiasis externa refers specifically to infestation that involves the lids and conjunctiva in man. Ophthalmomyiasis which originates from Germany is unusual, because the vector of the Oestrus ovis larvae is most prevalent in the warm climate of Mediterranean countries. The sheep nasal botfly (Oestrus ovis sp.) is responsible for most cases of external ophthalmomyiasis. This case report gives a detailed description of the larvae, their life cycle and an overview of infestations in Germany as well as the therapy of ophthalmomyiasis. CASE REPORT: At the end of August 1999, a 28-year-old man attended the outpatient department of Giessen University Eye Clinic with a foreign body sensation in his left eye. He reported that something hit his left eye while he was climbing on his motorbike in the early evening hours. Shortly afterwards he had a foreign body sensation in his left eye. On history taking he reported no other ophthalmologic problems in the past. Slitlamp biomicroscopy revealed white, vivid, approximately 1.5-mm-long, light-sensitive maggots on the conjunctiva and under the upper lid. These were removed mechanically and the conjunctiva rinsed with saline. Local therapy was not applied. CONCLUSION: Infestation with larvae of O. ovis has to be considered not only in tourists from Mediterranean countries, but also in Germany in the late summer.

Diagnostic value of upper intestinal fiber endoscopy in primary small intestinal lymphoma. A prospective study by the Tunisian-French Intestinal Lymphoma Group.

To assess the diagnostic value of upper intestinal fiber endoscopy in primary small intestinal lymphomas observed in an underdeveloped Mediterranean country, the endoscopic records of 40 patients (Group A) offering histologic evidence of lymphoma were compared with those of 80 patients (Group B) displaying clinical findings of small intestinal disease, but who eventually proved to be free of lymphoma after a complete work-up. The endoscopic procedure reached the jejunum in 91% cases and was well tolerated with only one reversible complication. Five primary endoscopic patterns could be defined, occurring either alone or in various combinations. The infiltrated pattern was the most sensitive (0.80) and specific (0.96) finding with predictive positive and negative values reaching 0.88 and 0.93, followed by the nodular pattern (sensitivity 0.60, specificity 0.84). Other primary lesions (ulcerations, mosaic pattern, mucosal fold thickening alone) were either nonsensitive or nonspecific or both. The infiltrated pattern proved to be more valuable than any association of primary lesion. Per endoscopic biopsies were diagnostic of lymphoma in 85% cases. These findings strongly suggest that upper intestinal fiber endoscopy, using long ending view instruments should be the first investigation in patients suspected of small intestinal lymphoma in developing Mediterranean countries.

HLA-DRB1 alleles associated with polymyalgia rheumatica in northern Italy: correlation with disease severity.

OBJECTIVE: To examine the association of HLA-DRB1 alleles with polymyalgia rheumatica (PMR) in a Mediterranean country and to explore the role of HLA-DRB1 genes in determining disease severity. METHODS: A five year prospective follow up study of 92 consecutive PMR patients diagnosed by the secondary referral centre of rheumatology of Reggio Emilia, Italy was conducted. HLA-DRB1 alleles were determined in the 92 patients, in 29 DR4 positive rheumatoid arthritis (RA) patients, and in 148 controls from the same geographical area by polymerase chain reaction amplification and oligonucleotide hybridisation. RESULTS: No significant differences were observed in the frequencies of HLA-DRB1 types and in the expression of HLA-DRB 70-74 shared motif between PMR and controls. The frequency of the patients with double dose of epitope was low and not significantly different in PMR and in controls. No significant differences in the distribution of HLA-DR4 subtypes were observed between DR4+ PMR, DR+ RA, and DR4+ controls. Results of the univariate analysis indicated that an erythrocyte sedimentation rate (ESR) at diagnosis > 72 mm 1st h, the presence of HLA-DR1, DR10, rheumatoid epitope, and the type of rheumatoid epitope were significant risk factors associated with relapse/recurrence. Cox proportional hazards modelling identified two variables that independently increased the risk of relapse/recurrence: ESR at diagnosis > 72 mm 1st h (RR=1.5) and type 2 (encoded by a non-DR4 allele) rheumatoid epitope (RR=2.7). CONCLUSION: These data from a Mediterranean country showed no association of rheumatoid epitope with PMR in northern Italian patients. A high ESR at diagnosis and the presence of rheumatoid epitope encoded by a non-DR4 allele are independent valuable markers of disease severity.

General and cancer specific mortality of a population based cohort of patients with inflammatory bowel disease: the Florence Study.

BACKGROUND: A population based epidemiological study identified all the patients diagnosed with ulcerative colitis (UC) or Crohn's disease (CD) resident in the Florence area in the period 1978-1992. AIMS: To assess the mortality of unselected patients with inflammatory bowel disease (IBD) in a Mediterranean country. METHODS: Overall, 920 patients (689 UC and 231 CD) were followed until death or end of follow up (31 December 1996). Information on vital status was available for all except eight patients (0.9%); 70 deaths were identified (23 in patients with CD and 47 in patients with UC). Expected deaths were estimated on the basis of five year age group, gender, and calendar year national mortality rates. Standardised mortality ratios (SMR) and 95% confidence intervals were calculated. RESULTS: General mortality was significantly lower than expected in UC (SMR 0.6; 95% confidence interval 0.4 to 0.8), due to a reduced number of cardiovascular and, possibly, smoking related deaths. Cancers of the respiratory tract were significantly reduced in UC but tended to be increased in patients with CD. These latter patients had not only an increased cancer mortality but also a 40% increased risk of dying for all causes already evident in the first five year follow up period and persisting thereafter. In contrast, in patients with UC, SMRs were initially very low but tended to increase steadily over the follow up period. Gastrointestinal deaths were particularly increased in patients with CD, but only moderately in those with UC. Overall, there was some evidence of a twofold increased mortality for colorectal cancer, the risk being highest for rectal cancers in patients with UC. A non-significant excess of deaths due to haemolymphopoietic malignancies and suicides was also observed. CONCLUSIONS: This study, the first in a Mediterranean country, supports the existence of two divergent mortality patterns for patients with UC and CD, possibly explained by differences in smoking habits and by a greater severity of CD.

An epidemiologic study of acute coronary syndromes in northwestern Greece.

Acute coronary syndromes (ACS) represent the most common cause of morbidity and mortality in the Western world. Relative epidemiologic data for Greece, a Mediterranean country, are sparse. The aim of the study was to determine the incidence and the clinical presentations of ACS. Over a 1-year period we conducted a prospective, population-based survey of ACS cases in an isolated area of northwestern (NW) Greece with 170,000 inhabitants. Every patient living in the study area, aged <80 years, without history of coronary artery disease, who presented with symptoms suspicious for ACS and was hospitalized for at least 24 hours was eligible for inclusion in the study. For sudden cardiac deaths, relative information was obtained from the autopsy report or the physician who documented death. Additional information regarding timing and associated conditions was obtained from relatives. The diagnosis and classification of the studied cases was performed according to World Health Organization and European Society of Cardiology criteria. The authors identified 352 patients (265 men, 87 women, mean age 62.5 +/-10 and 68 +/-9.5 years, respectively) with first-appeared ACS (174 non-ST elevation, 105 ST elevation, 73 sudden cardiac deaths). Fifty-six patients with other forms of ischemic heart disease (stable angina, heart failure, and silent ischemia) were not included in the analysis. Moreover, 154 patients with chest pain and normal appearing EGG at rest, normal values for enzymes (CK, troponin), and negative exercise testing, as well as 77 patients with normal findings from coronary angiography studies, were also excluded. The annual incidence for the age group of 30-79 was 39/10,000 inhabitants (60.6 for men and 19 for women). The incidence of ACS increased with age in both sexes and was higher in men even after the age of 70. About one third of the ACS and half of the sudden cardiac deaths occurred in the age group of 70-79. Only 3 patients were successfully resuscitated. ACS are common in this area of NW Greece and the majority of them present in a form amenable to therapeutic manipulations. Twenty percent of patients died suddenly, and a very small percentage of these were successfully resuscitated. Preventive measures and acute management facilities need to be improved, even in a Mediterranean country where the incidence of ischemic heart disease is relatively lower than in northern European countries.

The Pro12Ala polymorphism in the peroxisome proliferator-activated receptor gamma2 gene is not associated with postprandial responses to glucose or fat tolerance tests in young healthy subjects: the European Atherosclerosis Research Study II.

This study investigated whether the Pro12Ala polymorphism of the peroxisome proliferator-activated receptor gamma2 (PPARgamma2) gene is associated with glucose and lipid metabolism in young healthy subjects participating in the European Atherosclerosis Research Study II. Men aged 18-28 years (n=675) were recruited from 14 university student populations in 11 European countries. At their first visit subjects had an oral glucose tolerance test and 1 week later an oral fat tolerance test. Lipid variables and genotype were measured centrally. The Ala allele frequency exhibited a clearcut north-to-south gradient through Europe, decreasing from 0.21 in Baltic countries to 0.07 in Mediterranean countries. There was no significant effect of the Pro12Ala polymorphism on fasting lipid, glucose, or insulin levels, nor on the postprandial changes in these variables after glucose and fat tolerance tests. Neither was the Pro12Ala polymorphism associated with body mass index. This study provides no evidence for a major effect of the Pro12Ala polymorphism on glucose and lipid metabolism in young healthy subjects. Since PPARgamma has a major role in adipogenesis, the differential effect of its polymorphism on weight and related metabolic disorders may become apparent only later in life.

Prevalence of factor V Leiden and G6PD 1311 silent mutations in Dalmatian population.

BACKGROUND: Factor V Leiden has been described as a common genetic risk factor for venous thromboembolism. The geographic distribution of this abnormality varies greatly, being high in Europe and almost absent in Asia and Africa. Particularly high prevalence is observed in some Mediterranean countries, which suggests the Mediterranean origin of this mutation. Similarly, prevalence of silent mutation 1311 of the G6PD gene seems to be higher among Mediterranean populations. Since the Dalmatian population (of south Croatia) geographically belongs to the Mediterranean populations we analyzed the prevalence of FV-Leiden and silent mutation 1311 in this region. Furthermore, because the coincidence of G6PD deficiency and venous thromboembolism was described earlier, we tested a possible association of FV-Leiden and G6PD deficiency. METHODS: One hundred sixty-eight healthy blood donors and 55 G6PD deficient individuals originating from the Dalmatian region were tested for the presence of FV-Leiden mutation and silent mutation 1311. RESULTS: Prevalence of FV-Leiden among blood donors was 2.4%, while among G6PD deficient individuals it was significantly higher, 11% (p=0.011). Prevalence of silent mutation 1311 among blood donors and G6PD deficient individuals was 21 and 15%, respectively. CONCLUSIONS: Observed allele frequencies among individuals originating from the Dalmatian region is similar to the neighboring European and Mediterranean populations. Interestingly, our results indicate the association of the FV-Leiden and G6PD deficiency and warrant further studies.

Surgical treatment of pulmonary hydatid disease: a comparison of children and adults.

BACKGROUND: Hydatid cyst still remains an important health problem in our country as in many Mediterranean countries. The disease may affect children, and its treatment may be challenging in this age group. Surgery is the primary way of treatment. In the current study, the features unique to childhood pulmonary hydatid disease are emphasized. METHODS: Between 1992 and 2003, 301 patients were operated on because of pulmonary hydatid cyst in our hospital; 44 of them were 14 years or younger. They were categorized as pediatric patients. We retrospectively evaluated the clinical data of the patients. RESULTS: The mean age of the patients was 10.6 +/- 3.7 years (5-14 years) in children and 32.2 +/- 14 years (16-75 years) in adults. The rate of intact cyst was 71% in children and 57% in adults (P = .07). The mean diameter of the cyst was 8.5 +/- 3.1 cm (3-15 cm) and 6.6 +/- 3 cm (2-16 cm) in children and adults, respectively (P < .001). The rate of parenchyme-saving procedures was 84.1% in children, whereas 94.9% in adults. Lobectomy was performed in 16% of children, whereas it was performed in 1.5% of adults (P < .001). Morbidity rates were 13.6% in children and 11.6% in adults. No children but 1 adult died. Long-term follow-up revealed the recurrence rates as 4.5% in children and 4.3% in adults. CONCLUSIONS: Surgery, the primary method of treatment of hydatid cyst, is safe. Parenchyma-saving procedures such as cystotomy and capitonnage should be performed as much as possible. Nevertheless, hydatid cyst can reach relatively larger dimensions in children than in adults, which causes parenchyme destruction eventually leading to lung resection.

Hepatitis C virus infection in Western Europe.

Hepatitis C virus (HCV) infection is now recognised as the most common infection causing chronic liver disease in Europe. Approximately 3% of the world population has been infected with HCV, which represents about 170 million chronic carriers at risk of developing serious complications with more than 5 million in Europe alone. In the general population, the prevalence varies geographically from about 0.5% in northern countries to 2% in Mediterranean countries. Among newly detected HCV cases, 40-60% have normal ALT levels, 80% are viraemic, while about 70% of newly detected HCV carriers present histologic liver disease. More than 75% of the cases remain to be identified. The residual risk for transmitting HCV by blood products is at present 1/200 000 units distributed. Intravenous drug users are currently the main risk group. The prevalence rate is about 80% and the yearly incidence varies between 4 and 6%. In haemodialysis patients, the prevalence ranges from 10% to 30% and the incidence from 3% to 7%. The source of infection for the 30% of cases without identifiable risk factor remains to be clarified and appropriate well-controlled case-control studies on large samples are necessary. Further training and information campaigns remain desirable to improve knowledge and awareness among health care professionals.

Dietary habits, lifestyle and cardiovascular risk factors in a clinically healthy Italian population: the 'Florence' diet is not Mediterranean.

OBJECTIVE: To evaluate dietary habits and lifestyle of Italian subjects, to provide current data on adequacy of the nutritional guidelines and recommendations especially in relation to primary prevention of cardiovascular diseases and to assess the influence of dietary habits on lipid profile and homocysteine levels. DESIGN: Cross-sectional. SETTING: Population-based study. SUBJECTS: A sample of 520 clinically healthy subjects (211 males, 309 females) with a mean age of 46 y, living in Florence area, Italy. INTERVENTIONS: Dietary pattern was assessed by trained dietitians through a semiquantitative food questionnaire. Fasting blood samples were drawn for assessment of lipid profile, homocysteine and circulating vitamins. RESULTS: Contribution from total fats was over 30% in about 70% of subjects and intake of saturated fatty acids (SFA) was above the recommended values in at least 40% of the study population. Furthermore, almost the whole (99.6%) population reported low intake of polyunsaturated fatty acids (PUFA). High levels of total cholesterol were present in over 40% of the study population, whereas abnormal values of LDL-cholesterol were observed in about 30%. High levels of homocysteine were found in 11.7% of the study population. An extremely high percentage of subjects reported low intake of vitamins, especially with regard to folic acid (89%), vitamin B(6) (70.1%) and vitamin E (99.6%). In a multiple linear regression model, circulating levels of vitamin B(12) and folic acid, and intake of alcohol and vitamin C resulted in being independently associated with homocysteine plasma levels. CONCLUSIONS: In a typical Mediterranean country, general outlines of Mediterranean diet are not completely followed, especially concerning total fats, SFA, PUFA and vitamins' intake.

Incidence, prevalence, and treatment of end-stage renal disease in the Middle East.

INTRODUCTION: This article reviews the status of end-stage renal disease in the Middle East, with emphasis on its incidence, prevalence, and treatment. METHODS: Data were obtained from English-language published literature through a Medline search over the past 40 years. Supplementary information was gathered from regional congresses and symposia, websites of specialized nephrology centers, and direct communications. RESULTS: Of the 14 Middle East countries, attention was focused on 10 countries with similar renal care systems: 7 Arabian Peninsula countries and 3 eastern Mediterranean countries. Collectively, they have a population of 72.5 million. Incidence of ESRD ranged between 64 and 212 patients per million population (pmp) with an average of 93 patients pmp. The lowest prevalence was 320, the highest was 462, and the average was 352 patients pmp. Hemodialysis is the preferred dialysis modality and is freely available in all countries for citizens. Non-citizen residents' access to hemodialysis is markedly restricted. Peritoneal dialysis is available on a limited scale. Renal transplantation is available in all countries with variable program activities. Most of the transplants are from living, related donors. Active deceased donor transplant programs exist in four countries. The results from countries with active programs are excellent, with 5-year patient and graft survival of > 90%. CONCLUSIONS: This review provides information on the incidence, prevalence and treatment modalities of ESRD in 10 Middle East countries.
