Abstract
Rare cases of Cryptococcus have been documented in patients living with multiple myeloma. To date there has been no documented evidence of cryptococcosis revealing multiple myeloma. We reported a 63-year-old man who had a 2-months history continuous holocranial headaches, morning vomiting, complaining of blurred vision and fever. The biologic and the imaging showed a Cryptococcus meningoencephalitis. The search for a cause of immunodeficiency revealed a multiple myeloma. The diagnosis for Cryptococcus was confirmed according to an India ink stain, blood and cerebrospinal fluid culture. The patient's treatment for multiple myeloma was initiated with a chemotherapy regimen. The evolution was good without complication. Cryptococcosis, especially in the neuro-meningeal form, is a serious, deadly opportunistic infection. The search of an underlining immunodeficiency must be systematic. In this case, it was associated with early stage multiple myeloma.

Abstract
La coagulation intravasculaire disséminée (CIVD) est une cause de mortalité redoutable en milieu de réanimation. L´utilisation du système de score de la société internationale sur la thrombose et l´hémostase (ISTH) permet de faciliter le diagnostic précoce de la CIVD. Nous présentons trois observations cliniques de CIVD d´étiologies différentes: un adénocarcinome prostatique, un choc septique et un hématome rétro-placentaire. Les tests d´hémostase nécessaires au calcul du score de la Société Internationale sur la Thrombose et l´Hémostase (ISTH) (numération plaquettaire, taux de prothrombine, fibrinogène et D-dimères) ont été régulièrement réalisés. D´autres tests complémentaires (recherche de complexes solubles, test de lyse des euglobulines, dosage des taux d´antithrombine, de protéine C activée et du facteur V) ont été également réalisés. L´utilisation du score ISTH permet de faciliter le diagnostic précoce de la CIVD.

Abstract
Coronary artery disease (CAD) is one of the chief causes of death in the world. Several
hypotheses have been promoted as for the origin of the disease, among which are genetic
predispositions and/or environmental factors. The aim of this study was to determine the
effect of factor V (FV) gene polymorphisms (Leiden, G1691A [FVL] and HR2 A4070G) and to
analyze their association with traditional risk factors in assessing the risk of CAD. Our
study population included 200 Tunisian patients with symptomatic CAD and a control group
of 300 participants matched for age and sex. All participants were genotyped for the FVL
and HR2 polymorphisms. Multivariate logistic regression was applied to analyze independent
factors associated with the risk of CAD. Our analysis showed that the FVL A allele
frequency (P < 10–3, odds ratio [OR] = 2.81, 95% confidence
interval [CI] = 1.6-4.9) and GA genotype (P < 10–3, OR =
4.03, 95% CI = 2.1-7.6) are significantly more prevalent among patients with CAD compared
to those controls and may be predisposing to CAD. We further found that the FVL mutation
is an independent risk factor whose effect is not modified by other factors (smoking,
diabetes, hypertension, dyslipidemia, and a family history of CAD) in increasing the risk
of the disease. However, analysis of FV HR2 variation does not show any statistically
significant association with CAD. The FVL polymorphism may be an independent risk factor
for CAD. However, further investigations on these polymorphisms and their possible
synergisms with traditional risk factors for CAD could help to ascertain better
predictability for CAD susceptibility.

Abstract
OBJECTIVE The aim of this study was to determine whether plasminogen activator inhibitor 1 (PAI-1) is associated with the risk of Alzheimer's disease (AD) in Tunisian patients. DESIGN AND METHODS We analyzed the genotype and allele frequency distribution of the PAI-1 polymorphism in 60 Tunisian patients with AD and 120 healthy controls. RESULTS The results show a significantly increased risk of AD in carriers of the 4G/4G and 4G/5G genotypes versus the wild-type 5G/5G genotype (4G/4G: 28.33% in patients vs 10.0% in controls; P < 10-3; OR = 8.78; 4G/5G: 55.0% in patients vs 38.33% in controls; OR = 4.45; P < 10-3). The 4G allele was also more frequently found in patients compared with controls; P < 10-3; OR = 3.07. For all participants and by gender, homozygotic carriers (4G/4G) were at an increased risk of AD over heterozygotes and women were at an increased risk over their male genotype counterparts. The odds ratio for AD among 4G/4G carriers for any group was approximately twice that of heterozygotes in the same group. Women homozygotes ranked highest for AD risk (OR = 20.8) and, in fact, women heterozygotes (OR = 9.03) ranked higher for risk than male homozygotes (OR = 6.12). CONCLUSION These preliminary exploratory results should be confirmed in a larger study.

Abstract
BACKGROUND Autoimmune diseases and schizophrenia share many common features. Association studies confirm a shared genetic association in the human leukocyte antigen (HLA) region between schizophrenia and most autoimmune diseases. To our knowledge, the simultaneous syndromes of Graves' disease (GD) and type 2 diabetes (T2D) in schizophrenia are rare in Tunisia. CASE PRESENTATION We report a case of a 42-year-old woman admitted to the department of psychiatry for an acute relapse of chronic schizophrenia. Her medical history revealed that she was followed for Graves' disease and for a type 2 diabetes mellitus. A low-resolution HLA typing was performed by polymerase chain reaction sequence-specific primer (PCR-SSP) techniques according to determine the patient's haplotype. CONCLUSIONS Our study suggests that the HLA DRB1*03 allele may explain a common etiology underlying the co-morbidity of Graves' disease, type 2 diabetes, and schizophrenia in our patient.

Abstract
BACKGROUND The angiotensin-converting enzyme gene (ACE) insertion/deletion (I/D or indel) polymorphism has long been linked to Alzheimer's disease (AD), but the interpretation of established data remains controversial. The aim of this study was to determine whether the angiotensin-converting enzyme is associated with the risk of Alzheimer's disease in Tunisian patients. METHODS We analyzed the genotype and allele frequency distribution of the ACE I/D gene polymorphism in 60 Tunisian AD patients and 120 healthy controls. RESULTS There is a significantly increased risk of AD in carriers of the D/D genotype (51.67% in patients vs. 31.67% in controls; p = .008, OR = 2.32). The D allele was also more frequently found in patients compared with controls (71.67% vs. 56.25%; p = .003, OR = 2.0). Moreover, as assessed by the Mini-Mental State Examination, patient D/D carriers were more frequently found to score in the severe category of dementia (65%) as compared to the moderate category (32%) or mild category (3%). CONCLUSIONS The D/D genotype and D allele of the ACE I/D polymorphism were associated with an increased risk in the development of AD in a Tunisian population. Furthermore, at the time of patient evaluation (average age 75 years), patients suffering with severe dementia were found predominantly in D/D carriers and, conversely, the D/D genotype and D allele were more frequently found in AD patients with severe dementia. These preliminary exploratory results should be confirmed in larger studies and further work is required to explore and interpret possible alternative findings in diverse populations.

Abstract
BACKGROUND Coronary artery disease (CAD), also known as atherosclerotic heart disease, is a leading cause of mortality and morbidity throughout the world. The role of insertion/deletion (I/D) polymorphisms of the angiotensin-converting enzyme (ACE) gene in the etiology of CAD remains to be more completely clarified. The aim of this study was to determine the role of the ACE I/D polymorphism in patients with CAD and to study the association together with traditional risk factors in assessing the risk of CAD. METHODS Our study population included 145 Tunisian patients with symptomatic CAD and a control group of 300 people matched for age and sex. All participants in the study were genotyped for the ACE I/D polymorphisms obtained by polymerase chain reaction amplification on genomic DNA. RESULTS Our analysis showed that the ACE D allele frequency ( P < 10-3; odds ratio [OR] = 5.2; 95% confidence interval [CI] = 3.6-7.6) and DD genotype ( P < 10-3; OR = 6.8; 95% CI = 4.4-10) are significantly more prevalent among patients with CAD than in controls and may be predisposing to CAD. We further found that the risk of CAD is greatly potentiated by several concomitant risk factors (smoking, diabetes, hypertension, dyslipidemia, and a family history of CAD). CONCLUSION The ACE D allele may be predictive in individuals who may be at risk of developing CAD. Further investigations of these polymorphisms and their possible synergisms with traditional risk factors for CAD could help to ascertain better predictability for CAD susceptibility.

Abstract
The cause of thrombosis in hemodialysis vascular access is considered to be of a multifactorial nature, including stenosis of the venous or arterial connection. Therefore, identification of relevant thrombotic risk factors could lead to an improved antithrombotic therapy. This case control study was performed to evaluate the relationship between Factor V (G1691A and A4070G) and Factor II polymorphisms and vascular access thrombosis in hemodialysis patients. One hundred and twenty-one patients undergoing dialysis were selected as subjects. This sample was divided into two groups; a case group of 60 patients who had sustained one or more thrombotic events that resulted in vascular access failure and a control group of 61 patients, who never had a thrombotic occlusion of a functioning permanent dialysis access. Our data demonstrated a significantly increased risk of vascular access thrombosis in carriers of the mutant FV (G1691A and A4070G) polymorphisms (P < 0.05).Further studies on a large-scale population and other genetic variants will be needed to find candidate genes for vascular access thrombosis in hemodialysis patients.

Abstract
Apolipoprotein E ( APOE) is a member of the apolipoprotein gene family. APOE is polymorphic with 3 main allelic types: ∊2, ∊3, and ∊4. Certain of these alleles have been associated with higher vascular risk. However, the association of APOE genotypes with retinal biomarkers and risk of retinal stroke is less clear. This study evaluated the role of APOE polymorphisms in retinal vein occlusion (RVO). In the present study, 2-point mutations coding amino acid residues 112 and 158 were amplified using the polymerase chain reaction (PCR) from DNA extracted from Tunisian participants. APOE genotypes were determined by multiplex PCR followed by molecular hybridization. Eighty-eight patients (26 women and 62 men) and 100 age- and gender-matched healthy participants were enrolled. The statistical study revealed a higher frequency of the ∊4 allele in patients as compared to controls (27.3% vs 9%) with a significant association of the ∊4 allele with the disease ( P < 10−3, Pa < 10−3, odds ratio [OR] = 3.8, 95% confidence interval [CI] = 2.1-6.8). The frequency of the ∊3 allele was significantly lower in the patients with RVO compared to the controls (60.2% vs 82.5%, respectively; P < 10−3, Pa < 10−3, OR = 0.32, 95% CI = 0.19-0.53). The ∊3 allele seems to be protective against the disease. There was no association between the APO ∊2 allele and RVO. The association of APOE allele and genotype with RVO requires further investigation in different populations.

Abstract
OBJECTIVE The present study evaluated the role of the methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C gene polymorphisms and correlated these results with plasma homocysteine (Hcy) levels in Tunisian ischemic stroke (IS) patients. METHODS Overall, 84 patients with IS were included and compared with 100 healthy controls. The most common stroke risk factors were investigated. Fasting plasma Hcy levels were measured. Genotyping of the MTHFR C677T and A1298 polymorphisms was studied by polymerase chain reaction. RESULTS Aside from tobacco and alcohol use, the other studied factors were significant risk factors for IS. Mean plasma Hcy levels were significantly higher in IS patients than in controls (16.1 ± 8.28 μmol/L versus 8.76 ± 3.48 μmol/L, P < 10(-3)). Significant associations were found with both the MTHFR 677(CT + TT) and 1298 (AC + CC) genotypes in comparison with controls (P < 10(-3)). A significant synergistic interaction was also found with the double heterozygote MTHFR 677CT/1298AC (P < 10(-3)). Homocysteine levels were significantly higher in IS patients with the MTHFR C677T variant (CT and TT genotypes) (P < 10(-3)); however, the difference was not significant with the MTHFR A1298C variant (AC and CC genotypes) (P = .31). CONCLUSION The MTHFR C677T and A1298 polymorphisms (individually or in concert) and hyperhomocysteinemia represent important risk factors for IS. Elevated Hcy levels were found to be associated with the MTHFR C677T variant; however, no significant association was found with the MTHFR A1298C variant.

Abstract
BACKGROUND AND OBJECTIVE Multiple sclerosis (MS) is a chronic neurological disease characterized by central nervous system (CNS) inflammation and demyelination of nerve axons. The aim of this study was to investigate a possible association between the methylenetetrahydrofolate reductase (MTHFR) gene and multiple sclerosis in Tunisian patients. PATIENTS AND METHODS The genotyping of two missense variants of the methylenetetrahydrofolate reductase (MTHFR) gene, C677T and A1298C was performed in 80 multiple sclerosis patients and 200 healthy controls. RESULTS No significant differences were found in the frequency of the MTHFR C677T polymorphism between MS patients and healthy controls. However, the genotype prevalence of the missense variant MTHFR A1298C was significantly different between patients and controls (A/C: 55% versus 7%, p<10(-3); C/C: 13.75% versus 0%, p<10(-3), respectively). CONCLUSION Although our preliminary findings suggest no association between the MTHFR C677T variants and MS, there is evidence to suggest a significant association between the MTHFR A1298C polymorphisms and MS.

Abstract
The importance of the extrinsic haemostatic system, of which factor VII/VIIa (FVII/FVIIa) is a key constituent, in acute coronary syndrome (ACS) is well recognized. The contribution of FVII gene variants R353Q and -323P0/10, and altered FVII plasma levels to the risk of ACS was investigated in a North African Tunisian Arab cohort consisting of 308 ACS cases and 312 age-, gender- and ethnically-matched control subjects; FVII antigen levels were determined by ELISA. Regression analysis was used in assessing the association of FVII variants and changes in FVII levels to the overall risk of ACS. Significantly higher FVII antigen levels were seen in ACS patients (P < 0.001), and were associated with ACS and with ACS severity, and this association was confirmed by multivariate regression analysis, after adjusting for a number of confounders (BMI, smoking, systolic blood pressure, hypertension, diabetes, and glucose, cholesterol, and triglycerides levels). While the carriage of 353Q allele, was associated with significant reduction in FVII plasma levels, the distribution of the R353Q genotypes was comparable between cases and control subjects, thereby indicating that altered FVII levels, independent of R353 variant, were associated with increased risk of ACS. In contrast, the -323Ins variant, while not associated with altered FVII plasma levels, was associated with ACS, following adjustment for BMI, smoking, systolic blood pressure, hypertension, diabetes, and glucose, cholesterol, triglycerides and FVII levels. In summary, elevated FVII levels, and the -323P0/10 but not R353Q polymorphism, constitute risk factors for ACS.

Abstract
We investigated the contribution of JAK2 rs2203724 and STAT3 rs1053023 and rs1053004 to the susceptibility of idiopathic recurrent miscarriage (IRM) in Bahraini (246 cases and 279 controls) and Tunisian (235 cases and 235 controls) Arabs. The distribution of JAK2 rs2203724 and STAT3 rs1053023 genotypes were in Hardy-Weinberg equilibrium (HWE) in both communities, while mild deviation from HWE was noted for rs1053004 in Tunisians but not Bahraini. JAK2 rs2203724 was not associated with IRM in either community, while STAT3 rs1053023 was positively associated with IRM in both Bahraini and Tunisian women. STAT3 rs1053004 displayed mixed association: it was positively associated with IRM in Bahraini (P < 0.001), but not Tunisian women (P = 0.10). Genotype association confirmed the association of both STAT3 variants with IRM under additive, dominant, and recessive models, while the association of STAT3 rs1053023 was seen under additive and dominant, but not recessive models in Tunisians. The contribution of JAK2 and STAT3 variants to IRM susceptibility must be evaluated regarding specific variants, and the ethnic/racial background.

Abstract
BACKGROUND AND OBJECTIVES A state of low-grade inflammation accompanies the pathogenesis of atherosclerotic events. Interleukin-6 (IL-6) is a pleotropic pro-inflammatory cytokine that modulates the development of acute coronary syndromes (ACSs), partly by destabilizing coronary atherosclerotic plaques. We have examined the contribution of the -174G>C IL-6 promoter variant on the risk of coronary artery disease (CAD) among Tunisians. PATIENTS AND METHODS Study subjects included 418 CAD patients and 406 age- and sex-matched controls. IL-6 genotyping was done by PCR-restriction fragment length polymorphism. RESULTS The frequency of the -174C allele (mutant) was lower in Tunisians than in Europeans, and the distribution of -174 G>C genotypes was similar between CAD patients and control subjects. Moreover, compared to GG genotype carriers, -174C allele carriage did not increase the CAD relative risk (odds ratio and 95% confidence interval=1.09 and 0.80-1.49), which remained nonsignificant after adjusting for traditional risk factors for CAD (age, smoking, hypertension, diabetes and obesity). CONCLUSION The -174G>C IL-6 promoter variant is not associated with an increased risk of CAD among Tunisians.

Abstract
The contribution of human platelet antigen (HPA)-1 (GPIIb/IIIa), HPA-2 (GPIb/IX), and HPA-3 (GPIIb/IIIa) polymorphisms to the risk of coronary artery disease (CAD) was investigated in 341 CAD patients and 316 matched control subjects. HPA genotyping was performed by PCR-SSP. Regression analysis was employed in assessing the contribution of these variants to CAD risk. The frequency of HPA-1b (P = .009) and HPA-3b (P = .004) alleles, and HPA-1a/1b (P = .045), HPA-1b/1b (P = .007), and HPA-3b/3b (P = .008) genotypes were higher in patients than control subjects. No significant association was demonstrated between the HPA variants and 1-, 2- and 3-vessel disease. HPA-1b/2a/3b (Pc = .021) and HPA-1b/2b/3a (Pc = .002) haplotypes were positively associated with CAD, thereby conferring a disease susceptibility nature to these haplotypes. Multivariate analysis confirmed the positive association of HPA-1b/2a/3b (aOR = 3.72; 95% CI = 1.49-9.28), and in addition identified HPA-1b/2a/3a (aOR = 2.49; 95% CI = 1.06-5.86) to be positively associated with CAD, after adjusting for a number of covariates. Our results demonstrate positive association of HPA variants and specific HPA-1/HPA-2/HPA-3 haplotypes with CAD in Tunisians.

Abstract
Factor V G1691A (FV-Leiden) and prothrombin (PRT) G20210A single nucleotide polymorphisms (SNPs) were associated with venous thrombosis among Caucasians. We assessed the contribution of both SNPs to the genetic susceptibility of deep venous thrombosis (DVT) among Lebanese and Tunisian patients. Subjects comprised 198 DVT patients and 540 healthy controls from Lebanon and 126 Tunisian DVT patients and 197 control subjects; FV-Leiden (MnlI) and PRT G20210A (HindIII) genotyping was done by PCR-RFLP. While the prevalence of FV-Leiden mutant A allele and the G/A and A/A genotypes were significantly higher among DVT patients from Lebanon and Tunisia, the association of PRT G20210A with DVT was pronounced among Lebanese but not Tunisian patients. The prevalence of PRT G20210A mutant A allele (P < 0.001 vs. P = 181) and G/A genotype (P < 0.001 vs. P = 0.994) was significantly higher among Lebanese but not Tunisians, respectively. While FV-Leiden was a common genetic risk factor for DVT in both communities, the contribution of PRT G20210A to the genetic susceptibility of DVT differed among Lebanese and Tunisians, which underscores the need to determine prothrombotic gene polymorphisms associated with DVT among Arab and Mediterranean basin communities.

Abstract
Thrombophilia was implicated in the development of pregnancy complications, including recurrent idiopathic pregnancy loss, and is aggravated in women who are carriers of factor V G1691A (FV Leiden) and prothrombin (PRT) G20210A single-nucleotide polymorphisms (SNPs). Previous studies examined the role of FV-Leiden and PRT G20210A in recurrent pregnancy loss with conflicting results. Here we examined the prevalence of FV Leiden and PRT G20210A SNPs, in 200 women with 3 or more consecutive early (n = 87), late (n = 41), or early-late (n = 72) recurrent pregnancy losses, and 200 age-matched fertile parous control women. APC resistance (APCR) was detected functionally (measuring the activated clotting time triggered by activated factor X in presence of a fixed amount of purified APC), and FV-Leiden and PRT G20210A genotypes were assessed by PCR. The frequency of the mutant FV (0.1400 vs. 0.0276; P < 0.001) but not PRT 20210 (0.0100 vs. 0.0225; P = 0.159) allele was higher in patients than controls, respectively. APC resistance with factor V Leiden was seen in 27% of patients compared to 11.5% of controls, while APC resistance without factor V Leiden was seen in 12.5% of patients compared to 9.5% of controls. Regression analysis demonstrated that the significant predictors for early abortion was FV Leiden; those for late abortion were oral contraceptive, APCR, and FV Leiden; and predictors for early-late abortions were oral contraceptives, obesity, FV Leiden, and smoking. APC resistance and FV Leiden, as well as combination of both, are common thrombotic defects seen in women with idiopathic recurrent pregnancy loss, thus testing for these is recommended in women who have experienced recurrent miscarriages.

Abstract
OBJECTIVE We assessed the prevalence of inherited (FV-Leiden and PRT G20210A), and acquired (anti-PL antibodies) risk factors among habitual aborters in Tunisia. STUDY DESIGN We studied prospectively 146 patients with > or =3 consecutive early, late, or early-late recurrent pregnancy losses, together with 99 age-matched controls. Anticardiolipin antibodies (ACL), lupus anticoagulant (LA), and APC resistance (APCR) were detected by ELISA, dilute Russell Viper Venom Time (dRVVT), and coagulation tests, respectively, and FV-Leiden and PRT G20210A genotypes were assessed by PCR. RESULTS Anti-PL antibody frequencies were 45 and 9% among patients and controls, respectively (P < 0.001), with positive LA only (P = 0.004), or combined elevated ACL-positive LA being consistently higher (P < 0.001) among patients than controls. FV-Leiden (20.54% versus 6.06%), but not PRT G20210A (2.74% versus 4.04%) was significantly higher in patients versus controls. Among LA-positive cases higher prevalence of G/A (14/146 versus 1/99) and A/A genotypes (4/146 versus 0/99) were seen, and among ACL-positive cases higher prevalence of G/A (10/146 versus 0/99) and A/A genotypes (2/146 versus 0/99) were recorded. CONCLUSIONS Anti-PL antibodies and FV-Leiden, but not PRT G20210A, are associated with recurrent idiopathic pregnancy losses in Tunisian women.

Abstract
The present survey was carried out in the Military Center of Blood Transfusion from January 1998 to December 2001. 63,375 blood donors were concerned coming from different regions of Tunisia. Gene frequencies were found as follows: O = 0.686, A = 0.196 and B = 0.120. Important variations are observed between different regions of the country. The comparison with other countries' results traces the history of the Tunisian population, Tunisia being a strategic point in the Mediterranean region.

Abstract
The biallelic NA antigen system is of special interest as the NA antigens are frequent targets of neutrophil antibodies, causing alloimmune neonatal neutropenia, blood transfusion reactions, and chronic benign autoimmune neutropenia in infancy. Neutrophils isolated from the peripheral blood of 119 unrelated individuals at the National Blood Center were phenotyped for NA1 and NA2 using a granulocyte immunofluorescence assay. A subsequent analysis of the phenotyping study showed that the NA1 and NA2 antigen frequencies were 0.529 and 0.865 respectively, and that the estimated NA1 and NA2 gene frequencies were 0.313 and 0.632 respectively. In conclusion, it was determined that the Tunisian population is of Caucasian origin. However, to validate this finding, further investigations are necessary.

Abstract
Antiphospholipid antibodies were investigated in 37 individuals with sickle cell disease and compared to a control group of 30 healthy subjects. Sickle cell patients included 18 homozygous sickle cell patients, 8 S/beta thalassemic patients and 11 sickle cell trait subjects. In all individuals, antiphospholipid antibodies were explored by lupus anticoagulant (LA) detection and the quantification of IgG and IgM anticardiolipin (aCL) isotypes, total antiphospholipid antibodies (APA) and IgM, IgG and IgA antiphospholipid classes. In homozygous sickle cell patients, mean level of IgG aCL and total APA were significantly increased (17.02 +/- 8.88 GPL/ml, p < 0.05 and 10.64 +/- 10.58 UPL/ml, p < 0.05 respectively). The IgG aCL, total APA and LA frequencies were 22.2%, 44.4% and 62.2%, respectively. APA isotypes were mostly IgG or IgG and IgA. In S/beta thalassemic patients, mean levels of APA were significantly increased (10.81 +/- 7.82 UPL/ml, p< 0.05). Their frequency was 71.4% and they were mostly IgG or IgG and IgA. In patients with sickle cell trait, mean levels of APA were significantly increased (10.84 +/- 5.84 UPL/ml, p < 0.01). Their frequency was 72.7% and mostly of IgG isotype. Our study showed a close association between high APA levels and sickle cell syndrome, however there was no relationship between high levels of antiphospholipid antibodies and the major complications of sickle cell disease.

Abstract
87 pregnancies in diabetic women older than 35 years at time of conception were studied. 3% were insulin-dependent diabetes mellitus (IDDM), 52% non insulin-dependent diabetes mellitus (NIDDM) and 45% gestational diabetes mellitus (GDM). Mean age was 38 +/- 3 years; BMI was 33.2 +/- 7.0 kg/m2; gestation rate was 5 +/- 3 and number of alive children was 2 +/- 2. Only 3% of pregnancies were planned. Mean time of reference to diabetic care unit was 17 +/- 10 weeks. 95% of the women required human insulin. Mean total daily insulin dose was 0.49 +/- 0.28 UI/kg/d, increasing with gestational age. Mean fasting glycemia was 6.85 +/- 1.93 mmol/l and mean post-prandial glycemia was 8.29 +/- 2.52 mmol/l. Mean time of delivery was 38 +/- 2.1 weeks (less than 37 weeks in 9%). Cesarean section was performed in 44% of 34 cases. Death in utero occurred in 11% of 54 cases, postnatal death in 4%, congenital malformations in 4%, macrosomia in 40%. 9% of infants received intensive neonatal care. No difference was found between NIDDM and GDM about outcome of pregnancy. These results underlined importance of early screening for GDM as most cases seem to be undiagnosed pregravid diabetes mellitus (DM).

Abstract
The aim of this in vitro study was to sketch the subtle anticoagulant profile of iopamidol 300 mg l/ml (low osmolality non ionic contrast medium) and meglumine amidotrizoate 370 mg l/ml (high osmolality ionic contrast medium) in situations where variable amounts of clotting factors are observed and to check whether thrombin-generation significantly occurred in non anticoagulated blood-contrast materials mixtures. In the first experiment, mixtures of deficient plasmas with a routine plasma pool provided different ranges with variable amounts of clotting factors II, V, VIII, X, XI and XII. For each clotting factor level studied within these ranges, an activated partial thromboplastin time was determined with either contrast material loaded thromboplastin (5% v/v) or glucose loaded thromboplastin (5% v/v) used as a control. In the second experiment fibrino-peptide A (FpA) or modified antithrombin III (ATM) assays were performed in either (9:1) non anti-coagulated blood contrast materials mixtures or blood-glucose mixtures (control). Differing aPTT prolongation profiles were observed when clotting factors V, VIII, XI and XII were lowered in the plasma. However, neither iopamidol nor amidotrizoate induced an aPTT prolongation with decreasing clotting factor II. In the second experiment no significant thrombin generation was observed as both blood-contrast materials mixtures showed significantly lower FpA and ATM levels (p < 0.001) than glucose control after 5 minutes and 10 minutes incubation at room temperature. These findings provide evidence that the use of iopamidol in angiographic procedures does not increase risk of clotting or hemorrhage.

Abstract
The fibrinolytic potential was evaluated in 37 patients with homozygous sickle cell disease and compared to a control group of 30 age- and sex-matched healthy volunteers. In all individuals, the euglobulin clot lysis time and plasma antigen levels of t-Pa and PAI-1 were measured before and after venous occlusion (v.o) for 10 min. The global fibrinolytic activity was normal in 4 patients (good responders to v.o), while it was decreased in 33 patients (poor responders to v.o). Among the latter, 22 patients had significantly increased baseline levels of PAI-1 Ag (82.6 +/- 27.5 ng/ml, p < 0.001) and a normal release of t-Pa Ag after v.o. In contrast, 11 patients had basal values of PAI-1 Ag comparable to those in controls with a defective release of t-Pa Ag after v.o (11.4 +/- 5.2 ng/ml, p < 0.01). These data provide evidence for reduced fibrinolytic capacity resulting from either increased basal levels of PAI-1 or defective release of t-PA.

Abstract
Abnormalities of coagulation and fibrinolysis were studied in a group of 28 children and young adults with homozygous sickle cell disease (SCD), either in the steady state (n = 12) or during painful crisis (n = 16). Coagulation was explored by standard clotting tests and by measurement of prothrombin complex factors, factor VIII (VIII:C) and antithrombin III (ATIII), protein C (PC) and protein S (PS) activities, while fibrinolytic potential was evaluated using D-dimer, tissue plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI-1) assays. In SCD patients, thrombin time (TT) was constantly shortened, both in the steady state (ratio to control 0.83 +/- 0.08, p < 0.0001) and in crisis (0.76 +/- 0.06, p < 0.0001). Mean levels of prothrombin complex were similar in asymptomatic patients to those in controls, but were significantly decreased during sickle cell crisis (p < 0.05 for factor V and p < 0.0001 for factors II, VII and X). Factor VIII:C was significantly increased, both in the steady state (207 +/- 35%, p < 0.0001) and during crisis (208 +/- 34%, p < 0.0001). PS activity was reduced int he steady state (81 +/- 12%, p < 0.01) and further diminished in crisis (68.5 +/- 27.5%, p < 0.001), while D-dimers were significantly elevated during sickle cell crisis (1028 +/- 675 ng/ml, p < 0.001). In all SCD patients, baseline levels of t-PA antigen were comparable to those in controls, whereas concentrations of PAI-1 antigen were significantly increased, either in the steady state (89.7 +/- 26.3 ng/ml, p < 0.0001) or in crisis (75.0 +/- 24.8 ng/ml, p < 0.0001). These results provide evidence for the presence of circulating activated clotting factors in SCD and for an imbalance of the profibrinolytic and antifibrinolytic systems most likely due to increased PAI-1 levels.
