Neuro-meningeal cryptococcal infection revealing a multiple myeloma

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.

[Disseminated intravascular coagulation: role of the International Society on Thrombosis and Haemostasis (ISTH) diagnostic scoring system]

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.

Contribution de la mutation C677T dans la persistance des signes négatifs dans la schizophrénie en Tunisie

Introduction

Le trouble schizophrénique se subdivise, en signes positifs et négatifs. Les symptômes négatifs (S−) sont hétérogènes, reflétant à la fois les symptômes intrinsèques à la schizophrénie, des symptômes résultant d’une dépression concomitante ou distraction en raison des symptômes positifs. Récemment, certains facteurs de risque génétiques impliqués dans la persistance des (S−) sont étudiés, notamment la mutation C677T du gène MTHFR.

Patients et méthodes

Notre étude a porté sur 60 patients schizophrènes recrutés au service de psychiatrie à l’hôpital militaire principal d’instruction de Tunis. La mutation C677T du gène MTHFR a été étudiée par la technique PCR-RFLP. La digestion enzymatique a été effectuée avec Hinf1.

Résultats et discussion

Notre étude a révélé que le génotype CT est statistiquement significatif (Δ2 = 15,15, p = 0,001). Ainsi, le génotype CT semble prédisposer à la persistance des (S−) chez les schizophrènes. Ceci peut être expliqué par le rôle que joue le gène MTHFR qui code pour l’enzyme indispensable à la réduction de l’acide folique afin d’être métaboliquement actif. Le folate actif étant impliqué dans la synthèse des neurotransmetteurs notamment la sérotonine, son déficit induit la persistance des (S−).

Conclusion

La mutation C677T semble jouer un rôle dans l’étiopathologie de la schizophrénie. Il est nécessaire de mieux l’appréhender afin de mettre en place de nouvelles stratégies de prise en charge de la maladie.

Association of FV G1691A Polymorphism but not A4070G With Coronary Artery Disease

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.

The Plasminogen Activator Inhibitor 1 4G/5G Polymorphism and the Risk of Alzheimer's Disease

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.

HLA DRB1*03 as a possible common etiology of schizophrenia, Graves' disease, and type 2 diabetes

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.

Association between an angiotensin-converting enzyme gene polymorphism and Alzheimer's disease in a Tunisian population

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.

The Effect of ACE I/D Polymorphisms Alone and With Concomitant Risk Factors on Coronary Artery Disease

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.

Association Between Thrombophilic Gene Mutations and the Risk of Vascular Access Thrombosis in Hemodialysis Patients

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.

Role of the Apolipoprotein E Polymorphisms in the Development of Retinal Vein Occlusion in a Tunisian Population: A Case–Control Study

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.

[Neurologic manifestations of sarcoidosis: A study of 18 cases]

INTRODUCTION

Sarcoidosis is a multisystemic granulomatous disease of unknown aetiology. Neurologic manifestations are found in 5 to 10% of cases.

PATIENTS AND METHODS

We conducted a retrospective study over 6-year period including 18 patients diagnosed with neurosarcoidosis in the Neurologic department of the Military Hospital of Instruction of Tunis. Clinical, radiological, therapeutic features and outcome were studied.

RESULTS

The mean age was 43.44 years. Neurologic signs were the first symptom in 10 cases. Peripheral nervous system impairment was often found. Meningitis was noted in 8 cases. Biological tests are not contributive for the diagnosis. The brain magnetic resonance imaging was pathologic in 10 cases. Corticosteroids were administrated in the majority of cases. Eight patients did not show any sign of improvement. Ten cases improved with treatment.

DISCUSSION AND CONCLUSION

Diagnosis of neurosarcoidosis is difficult because of its clinical and radiological polymorphism. It is based on a clinical history suggestive of neurosarcoidosis, laboratory, imaging and histological studies.

Limbic encephalitis associated with leucine-rich glioma-inactivated 1 antibodies

We describe the case of a patient with confirmed limbic encephalitis associated with leucine-rich glioma-inactivated 1 (LGI1) antibodies. A 59-year-old man presented to the Department of Neurology with bizarre behavior, memory loss, cognitive impairment, visual hallucinations, and myoclonus and facio-brachial dystonic seizures. A brain magnetic resonance imaging (MRI) revealed no hippocampal lesions. Blood tests showed hyponatremia. An electroencephalogram showed disorganization and slowing of background activity. Antiepileptic drugs were ineffective. The patient exhibited considerable improvement following immunotherapy. The diagnosis of limbic encephalitis associated with LGI1 antibodies should be considered in patients with clinical manifestations mimicking psychiatric disorders and in cases of refractory epilepsy especially with faciobrachial dystonic seizures. There is frequently hyponatremia, and cerebral MRI may be normal. Full recovery can be expected with early diagnosis and prompt treatment.

Association of HLA-DR/DQ polymorphisms with schizophrenia in Tunisian patients

BACKGROUND AND OBJECTIVES

The hypothesis that human leukocyte antigens (HLAs) confer susceptibility to schizophrenic disorders has been tested by studying linkage and association in family samples. Our goal was to evaluate the role of HLA in the risk of developing schizophrenia in a Tunisian population.

DESIGN AND SETTINGS

Blood samples for this case-control study were collected from patients of the Department of Psychiatry at the Military Hospital of Tunisia between July 2012 and May 2013.

METHODS

A total of 140 patients with schizophrenia were recruited for genetic analysis. Controls included 100 persons matched for age, sex, and risk factors. Participants were tested for HLA class II alleles. HLA-DRB1 and HLA-DQB1 alleles were genotyped using polymerase chain reaction sequence-specific primers.

RESULTS

This study indicates that the alleles most responsible for disease susceptibility are DRB1*03 (P < 10-3) and DQB1*02 (P < 10-3) (P denotes probability values). The most protective alleles are DRB1*13 (P=.013) and DQB1*05 (P < 10-3). Further results revealed that DRB1*0301/DQB1*0201(P < 10-3), DRB1*0401/DQB1*0301 (P < 10-3) and DRB1*1101/DQB1*0301 (P < 10-3) are haplotypes most conducive to disease susceptibility.

CONCLUSION

The present findings support an association between schizophrenia and the HLA-DR-DQ locus among a Tunisian population. To our knowledge, this is the first study performed to analyze the association of HLA DRB1/DQB1 alleles on schizophrenia susceptibility in Tunisia.

Thrombophilic risk factors in different types of retinal vein occlusion in Tunisian patients

BACKGROUND

Retinal vein occlusion (RVO) is the second most common cause of vision loss because of retinal vascular disease. There are 2 types of RVO: branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). The pathogenesis of RVO is multifactorial. The role of factor V Leiden (FVL) and prothrombin mutations was examined in patients with CRVO and BRVO.

METHODS

FVL and prothrombin were investigated by extracting DNA of 88 patients with RVO. Sixteen of the patients were diagnosed with CRVO, 4 with hemispheric retinal vein occlusion, and 68 with BRVO. The genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism.

RESULTS

Significant differences were found in the frequencies of the genotypes for both the FVL (G1691A) (P<10(-3), odds ratio [OR]=17.4, confidence interval [CI]=6.20-59) and prothrombin (G20210A) (P=.007, OR=5.11, CI=1.30-29) polymorphisms between RVO patients and healthy controls. Additionally, the frequency of the GA genotype for the G1691A polymorphism was significantly higher among the patients in a subset of BRVO compared with controls (P<10(-3), OR=21.4, CI=7.34-74.2). However, no statistically significant differences were found in the frequencies of the prothrombin G20210A polymorphism between the BRVO group and healthy controls (P=.09, OR=3.13, CI=64-19.9). The frequency of both G1691A and G20210A genotypes among the patients of a CRVO subgroup was significantly higher compared with controls (P<10(-3), OR=11.4, CI=2.94-44.2; P=.007, OR=10.8, CI=2.15-54.1, respectively), suggesting an association between these polymorphisms and CRVO.

CONCLUSIONS

Large study would be required to understand completely the contribution of these markers in the risk of all types of RVO.

Methylenetetrahydrofolate reductase (C677T and A1298C) polymorphisms, hyperhomocysteinemia, and ischemic stroke in Tunisian patients

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.

Apolipoprotein E genotypes associated with Alzheimer disease and concomitant stroke

BACKGROUND

The ɛ4 allele of the apolipoprotein E (APOE) gene is a well-characterized genetic risk factor for Alzheimer disease (AD). The association between stroke and a higher risk for AD has also been reported. Our study sought to determine the relationship between the APOE gene and AD and the comorbid risk of stroke.

METHODS

The subjects of this study consisted of 48 patients with AD and 48 members of a control group. All subjects were genotyped for APOE.

RESULTS

The results clearly show a significant increased risk of AD in carriers of the APOE ε3/ε4 genotype (P = .003, odds ratio [OR] = 4.1) or ε4 allele (P = .001, OR = 4.2). The risk for stroke in AD patients was also increased for carriers of the APOE ε3/ε4 genotype (P = .02, OR = 9.0) and for carriers of the APOE ε4 allele (P = .004, OR = 5.5).

CONCLUSIONS

The present study is the first to establish a relationship between APOE ε4 and concomitant AD and stroke in the Tunisian population.

Association of methylenetetrahydrofolate reductase polymorphisms with susceptibility to Alzheimer's disease

BACKGROUND

Genetic risk factors play an important role in the pathogenesis of Alzheimer's disease (AD). In this case-control study, we examined the C677T and A1298C polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene and their correlation with this pathology.

OBJECTIVE

To verify the association between MTHFR C677T and A1298C polymorphisms and Alzheimer's disease.

METHOD

This work was conducted as a case-control study. Cases consisted of thirty-eight patients and 100 individuals without dementia constituted the control group. Genotyping of MTHFR polymorphisms was performed on patients and controls.

RESULT

Genetic analyses did not indicate a significant association between the MTHFR C677T mutation and AD (C/T: 63.15% versus 39%, p=0.087). 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)). Our data suggest an association between the MTHFR A1298C mutation and AD; however, the MTHFR C677T mutation did not contribute to susceptibility for AD.

CONCLUSION

The MTHFR A1298C polymorphism is a possible risk factor for Alzheimer's disease.

Combination of factor V Leiden and MTHFR mutations in myocardial infarction

Identifying patients who are at high risk of suffering myocardial infarction can be done by determining risk factors or by the adoption of molecular genetic testing for inherited thrombophilia. We report a case of myocardial infarction at a young age. The patient complained of dyspnea (stage III) and a burning pain of severe intensity that radiated to the left retrosternal side, but was not associated with palpitations or diaphoresis. A number of biochemical parameters were normal except for an elevated creatinine phosphokinase (CPK) level. Genetic testing revealed the subject to be heterozygous for both the factor V leiden and MTHFR C677T polymorphisms. The combination of these two mutations may be a high risk factor for myocardial infarction. Genetic screening for inherited thrombophilia in young patients, especially in the presence of a common risk factor, may be useful for primary thrombopro.phylaxis and in asymptomatic relatives of patients.

Role of thrombophilia in vascular access thrombosis among chronic hemodialysis patients in Tunisia

Vascular access thrombosis represents a serious and common problem in hemodialysis patients. 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 some thrombophilias and vascular access thrombosis in hemodialysis patients. Seventy-eight patients undergoing dialysis (between May 2007 and September 2009) were selected as subjects. This sample was divided into two groups; a case group of 28 patients who had sustained one or more thrombotic events that resulted in vascular access failure and a control group of 50 patients, who had never had a thrombotic occlusion of a functioning permanent dialysis access. Antithrombin, protein C and protein S levels were measured. Also, both groups were tested for the factor V Leiden mutation, the prothrombin G20210A mutation, the methylene tetrahydrofolate reductase C677T and A1298C mutations. Among genetic mutations of factor V Leiden, prothrombin G20210A and methylene tetrahydrofolate reductase genes, the C677T methylene tetrahydrofolate reductase mutation was the only significant genetic cause of vascular access thrombosis (P=0.005). Our data demonstrated a significantly increased risk of vascular access thrombosis in carriers of the C677T methylene tetrahydrofolate reductase mutation.

The status of thrombophilic defects and non-O blood group as risk factors for gestational vascular complications among Tunisian women

AIMS

Our objectives were to assess inherited thrombophilia and non-O blood group for the risk of gestational vascular complications among the Tunisian population.

METHODS

This study comprised 203 test subjects with adverse pregnancy outcomes including recurrent pregnancy loss, intra-uterine growth retardation, pre-eclampsia and placental abruption. Each subgroup was matched with 100 controls and analyzed separately. All patients were evaluated for factor V Leiden, factor II G20210A mutations and for non-O blood group. Protein S, protein C and antithrombin levels were determined and deficiencies noted.

RESULTS

The factor V Leiden mutation, non-O blood group and protein C deficiency had the highest incidences among patients both as a whole and in the 4 subgroups. The factor II G20210A mutation, protein S and antithrombin deficiencies were not statistically significant risk factors.

CONCLUSION

Our results provide evidence for a significant association between the factor V mutation and placental abruption. Furthermore, we found that this and the non-O blood group independently increased the risk for intra-uterine growth retardation in our population.
