Clin Appl Thromb Hemost 2024; 30:10760296231223195. [PMID: 38225166 PMCID: PMC10793187 DOI: 10.1177/10760296231223195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 11/26/2023] [Accepted: 12/12/2023] [Indexed: 01/17/2024] Open
Abstract
Thrombophilia in venous thromboembolism (VTE) is multifactorial. Von Willebrand factor (vWF) plays a major role in primary hemostasis. While elevated vWF levels are well documented in VTE, findings related to its cleaving protease (ADAMTS-13) are contradicting. The aim of this study was to determine vWF, ADAMTS-13, and the multifactorial Thrombospondin-1 (TSP-1) protein levels in patients after 3-6 months following an unprovoked VTE episode. We also explored a possible association with factor V Leiden (FVL) mutation. vWF, ADAMTS-13 and TSP-1 were analyzed using ELISA kits in 60 VTE patients and 60 controls. Patients had higher levels of vWF antigen (P = .021), vWF collagen-binding activity (P = .008), and TSP-1 protein (P < .001) compared to controls. ADAMTS-13 antigen was lower in patients (P = .046) compared to controls but ADAMTS-13 activity was comparable between the two groups (P = .172). TSP-1 showed positive correlation with vWF antigen (rho = 0.303, P = .021) and negative correlation with ADAMTS-13 activity (rho = -0.244, P = .033) and ADAMTS-13 activity/vWF antigen ratio (rho = -0.348, P = .007). A significant association was found between the presence of FVL mutation and VTE (odds ratio (OR): 9.672 (95% confidence interval (CI) 2.074-45.091- P = .004), but no association was found between the mutation and the studied proteins (P > .05). There appears to be an imbalance between vWF and ADAMTS-13 in VTE patients even after 3-6 months following the onset of VTE. We report that the odds of developing VTE in carriers of FVL mutation are 9.672 times those without the mutation, but the presence of this mutation is not associated with the studied proteins.

Abstract
BACKGROUND Thrombophilia is a substantial source of indisposition and mortality in several countries, including Arab populations. Deep venous thrombosis (DVT) with or without pulmonary embolism (PE) is the prevalent clinical manifestation of thrombophilia. While many genetic risk factors for DVT are known, almost all associated with hemostasis, many genetic factors remain unexplained. Nowadays, Next Generation Sequencing (NGS) offers a potential solution that allows several candidate genes to be analyzed simultaneously at a reasonable expense. METHODS We performed variant screening in the thrombophilia associated genes in Factor V Leiden (FVL) mutation-negative patients using Ion Torrent Next-generation sequencing (NGS). Ion AmpliSeq panel for 18 genes was designed. Twenty-nine unrelated patients with idiopathic VTE were recruited for NGS. RESULTS We were able to identify 19 variants (1 novel and 18 previously reported) in 10 out of 18 targeted genes. Pathogenic variants were identified in 22 patients demonstrating mutation detection rates of 76%. Previously reported variants in the F5, MTHFR, PROS1, PROC, F8, F9, SERPINA10, SERPIND1, and HRG genes were recognized in 21 patients. More than one variant in the targeted genes was detected in some of the patients with VTE. We identified SERPINA10 recurrent variant p.(R88*) in seven patients representing 32% of VTE cases. Additionally, we report one novel variant c.356G > T, p.(G119V) in the F7 gene, considered to be pathogenic in this study. CONCLUSIONS Our studies finding illustrates the ability of targeted next-generation sequencing to uncover uncommon/unknown genetic variants that may predispose to thrombophilia. The finding of the novel variant in the F7 gene extends the spectrum of variants affecting thrombosis. While a comparatively small number of subjects have been included in our cohort, the findings summarize the possible genetic features of thrombophilia.

Abstract
AIMS The rate of laboratory referrals for thrombophilia patients' genetic workup was assessed and compared among the medical and surgical specialties and subspecialties at a major tertiary care center in Lebanon. METHODS DNA extraction was performed using the PEL-FREEZ extraction kit (PEL-FREEZ; DYNAL) and the Factor V, prothrombin, and methylenetetrahydrofolate reductase genotypic profiles were done using the FV-PTH-MTHFR StripAssay kit (ViennaLab) that employs a polymerase chain reaction-reverse hybridization method. A total of 2238 referred cases were analyzed. RESULTS Around 42.23% of all referred cases turned out to have a thrombosis-associated mutation. Referrals from medical and surgical specialties were almost equal. In the surgical specialty, most referrals came from the department of Obstetrics and Gynecology, while in the medical speciality, most of the workup referrals originated from the Hematology/Oncology physicians. However, low referral rates were reported from the emergency department and family medicine practitioners. CONCLUSION Genetic testing for thrombophilia workup is gaining more importance among the different medical and surgical specialties and is worth being introduced into the offered test lists of all established molecular diagnostics laboratories.

Abstract
Venous thromboembolic disorders (VTE) are serious disorders with high morbidity and mortality rates. Many genetic and acquired risk factors were identified to cause VTE. The most common genetic risk factor is Factor V Leiden mutation (FVL). FVL was found in high percentage of populations of Caucasian origin but was almost absent in non-Caucasians. It was also reported in populations living in North Africa and the Middle East. This review article briefly explains FVL and how it causes VTE, the distribution of FVL worldwide, and then it elaborates on the epidemiology of FVL in the Mediterranean Region and how this brought speculations that FVL might have originated in the Eastern Mediterranean area.

Abstract
INTRODUCTION Jugular vein thrombosis is mainly due to infectious, neoplastic and iatrogenic causes. Activated protein C (APC) resistance is an exceptional cause of jugular vein thrombosis. CASE REPORT A 40-year-old woman consulted for left lateral neck swelling present for two weeks. Neck ultrasound revealed left internal jugular vein thrombosis, which was confirmed by contrast CT. The rest of the examination, including routine clotting assessment and inflammatory work-up, was normal. Further investigations demonstrated APC resistance with Factor V Leiden mutation. Treatment consisted of oral anticoagulants with a good outcome. DISCUSSION APC resistance is a recently identified and relatively frequent cause of thrombophilia, mostly due to Factor V Leiden mutation. APC resistance is responsible for 20% to 50% of all thrombotic events. The laboratory diagnosis is based on two tests: a phenotypic test based on APTT with and without APC and a genotypic test based on detection of a Factor V Leiden mutation. CONCLUSION Screening for APC resistance and Factor V Leiden mutation is now part of the aetiological work-up of thromboses, particularly in subjects younger than 50. Treatment is based on oral anticoagulants.

Abstract
Factor V Leiden mutation (FVL; G1691A) is an established risk factor for venous thromboembolic disorders. FVL was reported with high prevalence in Caucasians (1-15%) but was absent in non-Caucasians like Africans and Asians. Studies reported FVL in 5-27% of Arabs and non-Arabs living in the Middle Eastern countries northern to the Arabian Peninsula, but was almost absent in Arabs in the Arabian Peninsula itself. Kuwait is an Arabic country present on the northern border of the Arabian Peninsula, and Kuwaitis are originally from Saudi Arabia (Southern to Kuwait and within the Arabian Peninsula) or from Iran and Iraq (northern to Kuwait and the Arabian Peninsula). This study was conducted to study FVL in Kuwaitis in relation to their origin. Real-time PCR was performed on DNA samples of 285 apparently healthy Kuwaitis using specially designed primers and probes for FVL. There were 109 Kuwaitis of Iranian origin, 71 of Iraqi origin and 105 of Saudi origin. FVL was present in 7 and 5 Kuwaitis of Iranian and Iraqi origin, respectively. None of the Kuwaitis of Saudi origin had the mutation. Prevalence of FVL in Kuwaitis of Iranian (6.42%) and Iraqi (7.04%) origin were statistically different from prevalence in Kuwaitis of Saudi (0%) origin (P-value<0.05). No difference was found between females and males (P-value>0.6). In conclusion, FVL is present in Kuwaitis of Iranian or Iraqi origin only. Therefore, testing and providing genetic consultation for FVL may be needed in those Kuwaitis only which should save time, cost and efforts. However, this assumption should be confirmed by other studies and on larger number of cases.
