Congenital analbuminemia (CAA) is a very rare genetic disorder characterized by a significant reduced or even complete absence of human serum albumin. Our data describe the clinical features and laboratory results of a case confirmed by mutation analysis of the albumin gene in a 35-year-old man presenting recurrent acute coronary syndrome. To the best of our knowledge, only two cases of coronary artery disease have been reported worldwide without recurrence.

Systemic markers of inflammation such as Interleukin-6, Tumor Necrosis Factor alpha and C-reactive protein have previously been shown to be associated with increased risk of cardiovascular events. The aim of the present study is to assess the role of variants in the IL-6 (- 174 G/C), TNFα (- 308 A/G) and CRP (+ 1059G/C) genes as susceptibility markers for CAD in a Tunisian population.

Methods And Results: A total of 169 faecal specimens, collected from diarrhoeic calves from several farms located in the central eastern regions of Tunisia, between January 2006 and October 2010, were analysed by semi-nested multiplex RT-PCRs for P and G genotypes identification or were genotyped by DNA sequencing. Positive samples were tested by TaqMan real-time RT-PCR to quantify the viral load.
Two genetically distinct bovine enteric caliciviruses are known: noroviruses of genogroup III (NoVsGIII), which are genetically related to human noroviruses, and neboviruses, which represent a new calicivirus genus. To investigate the presence of NoVsGIII and nebovirus strains in diarrheic calves in Tunisia, a total of 169 faecal specimens were collected from January 2006 to October 2010 from different cattle herds located in the central-east regions. RT-PCRs and sequencing were carried out using primers targeting the 3' end of the polymerase gene of NoVsGIII and neboviruses.

Hyperhomocysteinaemia is considered as an important independent risk factor for atherosclerosis and thrombotic disease. This study determined the distribution of homocysteine (Hcy) levels in healthy Tunisian subjects and evaluated the relationship between Hcy levels and some cardiovascular risk factors. Randomly selected subjects (592 men and 114 women) were recruited from different regions of Tunisia.

Introduction: Type 2 diabetes is a chronic disease associated to the presence of multiple risk factors. Among recently studied factors we cite PCR and micro-albumin.
Objective: In the present study we intend to determine the correlation between urine albumin excretion rate, CRP levels and type of vascular complications in type 2 diabetes.
Recently, homocysteine and new inflamatory biomarkers are demonstrated to be involved in cardiovascular diseases. These risk factors are not well studied in acute coronary syndrome. We investigated the distribution of homocysteine and inflammatory markers in patients with acute coronary syndrome and evaluated the association between these parameters and severity of the disease.

It has been detected in high amount in human serum collected from nephropathy patients, especially those categorized as having a chronic interstitial nephropathy of unknown etiology. In the present study, ochratoxin A levels were measured in commonly consumed food items and in serum samples from nephropathy and healthy subjects in Tunisia.

Aim: This preliminary study aimed to investigate whether hyperhomocysteinaemia and/or MTHFR C677T mutation are associated with ischemic stroke.
Background: An elevated level of homocysteine (Hcy) has been shown to be a cardiovascular risk factor in the majority of research studies. Recently, it was found to be associated with new risk factors such as inflammatory markers.
Objectives: To investigate the distribution of plasma total Hcy (tHcy) and the levels of inflammatory markers in patients with acute coronary syndrome (ACS), and to evaluate the association between these parameters and the severity of the disease.
The aims of our investigations were (1) to look for Aichi virus in environmental samples and (2) to compare the Aichi virus strains in both clinical and environmental samples in order to evaluate the role of environmental contamination as a possible vehicle for viral transmission. Aichi virus was detected in 15 (6%) sewage samples and in 4 (6.6%) shellfish samples.

Methods And Results: A total of 250 sewage (raw and treated) and 60 shellfish samples were collected between January 2003 and April 2007 in Monastir region, Tunisia. Group A rotavirus (RVA) was detected in 80 (32%) sewage samples, norovirus (NoV) in 11 (4·4%) and enteric adenovirus (AdV) in 1 (0·4%).
Aim: Evaluate the effect of lipopenic and hypotensive treatment on homocysteine levels.
Methods: We recruited 145 type 2 diabetics and 130 control subjects. Thirty-seven diabetics had no complications, 54 had microvascular complications and 54 had macrovascular complications.
Aichi virus has been described as a novel causative agent of gastroenteritis in humans. In this study, we report the seroprevalence distribution of Aichi virus in Tunisia. A panel of 1,000 sera was screened by applying an enzyme-linked immunosorbent assay for immunoglobulin G specific for Aichi virus.

Since current water treatments do not ensure their complete removal and they become contaminants of the water environment.
Aim: In order to monitor and assess the prevalence and the seasonal incidence of enteric viruses contaminating wastewater, a total of 93 samples were collected from the stations of Sayada-Lamta-Bouhjar and El Frina.

The use of reliable and specific diagnosis tools in patients of intensive care unit constitutes the best way to follow up these patients and to take charge of severe infections. It is in the context that the measuring of procalcitonin should be considered in order to prove its role in invasive candidosis. This prospective study included 52 patients from an intensive care unit.
