Is there any genetic predisposition of MMP-9 gene C1562T and MTHFR gene C677T polymorphisms with essential hypertension?

The current study was conducted to determine whether there is a relation between hypertension and two different polymorphisms, including C1562T of the Matrix metalloproteinase-9 (MMP-9) gene and C677T of the methylenetetrahydrofolate reductase (MTHFR) gene. Genomic DNA obtained from 224 persons (125 patients with hypertension and 99 healthy controls) were used in the study. Polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism and electrophoresis. The results were statistically analyzed and were found to be statistically significant. The frequencies of the C1562T genotypes were found to be, in controls CC 75.8 % and CT 24.2 % and in patients CC 71.2 %, and CT 28.8 %. The frequencies of C677T genotype were found to be, in controls CC 56.6 %, CT 38.4 and TT 5.1 % in controls and in patients CC 52 %, CT 30.4 % and TT 17.6 %. In conclusion, we may suggest that there is no relation between the essential hypertension and C1562T polymorphism of MMP-9 gene; on the other hand C677T polymorphism (genotype TT) of MTHFR gene can be regarded as a genetic indicator for the development of essential hypertension.Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT), Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research (KAKENHI): 2450132

An Atypical Presentation of Allergic Myocardial İnfarction

Acute coronary syndromes secondary to hypersensitivity reactions related with allergic factors are defined as Kounis syndrome. Doxycycline is an antibiotic commonly used in clinical practice. In this report, we described an atypical presentation of Kounis syndrome in a patient who was admitted to the emergency service complaining of chest pain, generalized rash and fever. She was taking doxycycline for 3 days because of urinary tract infection. Non specific ST-T changes were seen on electrocardiography, positive troponin levels were detected and global left ventricular wall motion abnormalities were defined by echocardiography. The patient had no conventional risk factor for acute coronary syndrome. Normal coronary angiography results, improved left ventricular functions and symptoms by antihistaminic and steroid treatments were consistent with Kounis syndrome. All patients admitted with the concurrence of chest pain and allergic symptoms should be asked about exposure to allergens. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 202-4

Koroner arter hastalığında MTHFR ve MMP-9 genetik variantları

Amaç: Koroner arter hastalığı (KAH), hem genetik hem de çevresel faktörlerden etkilenen çok faktörlü bir hasta- lıktır. Aday genlerdeki tek nükleotid polimorfizmleri (SNP) bu tür multifaktöryel hastalıklara yatkınlığa neden olurlar. Bu yüzden, KAH etiyopatogenezinde rol oynayan genler- de SNPlerin araştırılması, önemli hale gelir. Bu çalışma- da, KAH oluşumu üzerinde, matriks metalloproteinaz-9 (MMP9) -1562 C/T ve metilentetrahidrofolat redüktaz (MTHFR) 677 C/T polimorfizmlerinin bağımsız ve siner- jistik etkileri araştırıldı. Yöntemler: 109 koroner arter hastası ve 108 sağlıklı kontrol olmak üzere toplam 217 birey incelendi. MTHFR 677 C/T ve MMP-9 -1562 C/T polimorfizmleri için genotip- ler polimeraz zincir reaksiyonu (PCR)- restriksiyon frag- manı uzunluk polimorfizmi (RFLP) ile belirlendi. Bulgular: KAH ile MMP-9 -1562 C/T ve MTHFR - 677 C/T polimorfizmlerinin genotipleri ve alel frekansları arasında istatistiksel olarak anlamlı bir farklılık olmadığı bulundu. (p> 0.05) MMP9 -1562 C/T polimorfizmi için TT homo- zigot genotipi hiç bir grupta bulunmadı. Bununla birlikte, Güneydoğu Anadolu Bölgesinde C aleli ve CC genotipi her iki polimorfizm için hakim iken, TT genotipi ise çok nadir olarak bulundu. Sonuç: MTHFR 677 C/T ve MMP9 -1562 C/T polimor- fizmleri ile koroner arter hastalığı arasında ilişki bulunma- dı. Ancak Güneydoğu Anadolu bölgesinde TT genotipinin çok nadir olduğu belirlendi.Objective: Coronary artery disease (CAD) is a multifacto- rial disease that influenced by both genetic and environ- mental factors. Single nucleotide polymorphisms (SNPs) in the candidate genes produce susceptibility to such mul- tifactorial diseases. Therefore, investigations of SNPs, in the genes that may play role in etiopathogenesis of CAD, become crucial. In the present study we investigated the both independent and synergistically effects of matrix me- talloproteinase (MMP) -1562 C/T and methylenetetrahy- drofolate reductase (MTHFR) 677 C/T polymorphisms on the CAD occurrence. Methods: In total 217 individuals, 109 coronary artery disease patients and 108 healthy controls were exam- ined. We determined the genotypes for MMP-9 -1562 C/T and MTHFR 677 C/T polymorphisms by polymerase chain reaction (PCR)-restriction fragment length polymor- phism (RFLP). Results: We found no statistically significant differences between genotypes and allelic frequencies of both MMP- 9 -1562 C/T and MTHFR 677 C/T polymorphisms and CAD (p>0.05). No TT homozygous genotype was found in any of groups for MMP9 -1562 C/T polymorphism. However, while C allele and CC genotype was found to be highly, TT genotype was found to be very rare for both polymorphisms in Southeastern Anatolia. Conclusion: We have found no associations between MMP9 -1562 C/T and MTHFR 677 C/T polymorphisms and coronary artery disease. However, TT genotype was determined to be very rare in Southeast Anatoli
