The thiol/disulfide balance in ketone positive and ketone negative pregnant women with nausea and vomiting — a prospective study in a tertiary center

Objectives: We aimed to investigate the thiol/disulfide balance in ketone positive (hyperemesis gravidarum) and ketonenegative pregnant women with nausea and vomiting.Material and methods: A total of 60 patients under the 14th week of pregnancy were included in this study, and they weredivided into two groups. Group 1 included 30 pregnant women with ketone positive, group 2 included 30 ketone negativepregnant women with nausea, and vomiting.Results: The native thiol, disulfide, and total thiol concentrations were measured using an automated method and comparedamong the two groups. There were also three indexes that are derived from disulfide, native and total thiol (Index1 = 100 × disulfide/native thiol); (Index 2 = 100 × disulfide/total thiol); (Index 3 = 100 × native thiol/total thiol). Whencompared with Group 1 and Group 2, total thiol was high, native thiol was low but not statistically significant. Disulphide(p = 0.046), index 1 (p = 0.036) and index 3 (p = 0.034) were statistically significant.Conclusions: Patients with ketone positive are shifting to OS direction due to lack of nutrients and electrolytes. This studyemphasizes the therapeutic potential of antioxidant supplementation, which is becoming an increasingly used approachin treating the symptoms of women with ketone positive

Evaluation of catalase, myeloperoxidase and ferroxidase values in pregnant women with hyperemesis gravidarum

Objectives: To investigate maternal serum catalase, myeloperoxidase and ferroxidase levels in pregnant women with Hyperemesis Gravidarum and to compare the results with healthy pregnancies.  Material and methods: In this study, 60 female patients admitted to the Health Sciences University, Gazi Yaşargil Training and Research Hospital, Gynecology and Obstetrics Department were evaluated. The patients were divided into two groups: Group 1 included 30 pregnant women with hyperemesis gravidarum; Group 2 included 30 healthy pregnant women. Pregnancies over 14 weeks were excluded from the study.  Results: The laboratory and laboratory characteristics of both groups are shown in Table 1. No significant differences were found between the groups in terms of the maternal age, gestational age, gravidity, parity, fasting glucose level, and BMI. The maternal blood CAT levels were significantly higher in the HG group (219.6 ± 111.3 kU/L) when compared to the control group (71.5 ± 52.5 kU/L) (p < 0.001). The maternal blood MPO levels were lower in the control group (121.5 ± 36.3 U/L) than in the study group (90.9 ± 56.4 U/L) (p = 0.016). However, the ferroxidase levels were similar between the two groups. The independent variables BMI, age, parity, gravidity and gestational week effects were adjusted according to the logistic regression method with groups. Significant differences were observed between the two groups in the levels of CAT (0.001), MPO (0.005) values.  Conclusions: This study suggests that antioxidants in response to oxidative stress gave different reactions with different mechanisms; Also, we believe that insufficient food intake suppresses the immune system and this has an important role on antioxidants

Incidance of Familial Mediterranean Fever (FMF) Gene Mutations in Children in Van Region

Amaç: Ailesel Akdeniz Ateşi (AAA) otozomal resesif bir hastalık olup, periyodik karın ağrısı, ateş ve eklem ağrısına yol açan seröz membranların tekrarlayan inflamatuar ataklarıyla karakterizedir. MEFV genindeki mutasyonların hastalıktan sorumlu olduğu gösterilmiştir. Bu çalışmada Van ve çevresinde AAA tanısı ile takip edilen çocukların, MEFV geninin 12 mutasyonu açısından taranarak tekli veya birleşik mutasyonların oranlarının saptanması ve mutant bireyler içindeki homozigot ve heterozigot oranının tespiti amaçlanmıştır. Gereç ve yöntem: Bu amaçla 5-15 yaşlarında 157 hasta çalışmaya alındı. Hastalar klinik bulgularına göre aktif (n81) ve pasif (n76) grup olarak ikiye ayrıldı. Hastalarda revers hibridizasyon analizi ile MEFV gen mutasyonları incelendi. Bulgular: Hastaların %42,7'sinde heterozigot, %11,5'inde birleşik heterozigot ve %12,7'sinde homozigot olmak üzere toplam %66,87'sinde mutasyon saptandı. E148Q heterozigot (%22,92), M694V homozigot (%10,82) ve M694V heterozigot (%8,28) mutasyonları en sık izlenen mutasyonlardı. En sık tespit edilen alleller ise M694V (%40,0), E148Q (%32,41) ve V726A (%11,72) idi. Sonuç: Bu çalışmanın sonuçları AAA'lı hastalarda MEFV gen mutasyonundaki heterojeniteyi desteklemiş ve hastalarımızın geniş bir mutasyon yelpazesine sahip olduğunu göstermiştirBackground: Familial Mediterranean Fever (FMF) is an autosomal recessive disease and it is characterized by recurrent inflammatory attacks of the serous membranes which cause periodic abdominal pain, fever and joint pain. The mutations in the gene of MEFV have been determined to be responsible for the disease. The aim of this study was to screen MEFV gene for 12 mutations in children diagnosed with FMF and to detect alleles which were most frequently observed. Materials and methods: The study included 157 patients aged 5-15 years. The patients were divided into two groups as active (n 81) and passive (n 76) according to their clinical findings. Mutations of MEFV gene in patients were examined by analysis of reverse hybridization. Results: 66,87% of the total patients had mutation, of which 42,7% had heterozygous, 11,5% compound heterozygous and 12,7% homozygous mutations. The most frequently observed mutations were E148Q heterozygous (22,92%), M694V homozygous (10,82%) and M694V heterozygous (8,28%). The alleles which were detected most were M694V (40,0%), E148Q (32,41%) and V726A (11,72%). Conclusion: The results of this study have supported the heterogeneity of the mutation of MEFV gene in patients with FMF and have shown that our patients have a wide range of mutation

Cytokine Levels Of Familial Mediterranean Fever (FMF) in Attack and Remission Periods

Amaç: Ailesel Akdeniz Ateşi (AAA) otozomal resesif bir hastalık olup, periyodik karın ağrısı, ateş ve eklem ağrısına yol açan seröz membranların tekrarlayan inflamatuar ataklarıyla karakterizedir. MEFV genindeki mutasyonların hastalıktan sorumlu olduğu gösterilmişse de hastalığın fizyopatolojisi bilinenden daha karmaşık görünmektedir. Hastalığın patogenezinde çeşitli sitokinlerin de rol oynadığı düşünülmektedir. Gereç ve Yöntem: Bu çalışmada Van yöresinde AAA tanısı alan çocuklarda hastalığın aktif ve pasif dönemlerinde sitokin düzeylerinin kontrollerle karşılaştırılarak hastalığın gelişiminde sitokinlerin rolünün değerlendirilmesi amaçlandı. Bu amaçla 5-15 yaşlarında 157 hasta çalışmaya alındı. Hastalar klinik bulgularına göre aktif (n81) ve pasif (n76) grup olarak ikiye ayrıldı. Ayrıca kontrol grubu olarak 30 çocuk çalışmaya alındı. Hasta ve kontrol gruplarında IL-1?, IL-6, IL-8, IL-10, TNF-? ve CRP düzeyleri ölçüldü. Bulgular: IL-1? seviyeleri aktif grupta kontrol grubundan yüksek bulunurken, IL-8, TNF-? ve CRP seviyeleri hem aktif hem de pasif grupta kontrollerden daha yüksekti (p0,05). IL-6 seviyeleri ise hem aktif hem de pasif grupta kontrol grubundan yüksekken aynı zamanda aktif grubun seviyesi pasif gruptan da anlamlı olarak daha yüksekti (p0,001). Sonuç: Bu çalışmanın sonucunda, başta IL-6 olmak üzere IL-8, TNF-? ve CRP düzeylerinin akut atak tanısı ve tedaviye yanıtın izlenmesinde kullanılabileceğini düşündürmektedir. Yine pasif dönemde artmış sitokin düzeyleri bu hastalarda subklinik inflamasyonun devam ettiği görüşünü desteklemektedirObjective: Familial Mediterranean Fever (FMF) is an autosomal recessive disease, and it is characterized by recurrent inflammatory attacks of the serous membranes which cause periodic abdominal pain, fever and joint pain. The physiopathology of the disease seems more complex than it has been known. It has been considered that various cytokines have also played role in the pathogenesis of the disease. The aim of this study was to evaluate the role of cytokines in the development of the disease by comparing cytokine levels in controls and in active and passive periods of the disease in Van region. Materials and Methods: The study included 157 patients aged 5-15 years. The patients were divided into two groups as active (n 81) and passive (n 76) according to their clinical findings. In addition, 30 children were included in the study as a control group. Results: The level of IL-1? in the active group was found higher than that of the control group, the levels of IL-8, TNF-? and CRP were higher both in the active and in the passive group than the controls (p 0.05). While the levels of IL-6 both in the active and in the passive group were higher than those of the control group, the level of active group was also significantly higher than that of the passive group (p 0,001). Conclusion: The results of this study thought that, the levels of IL-8, TNF-?, CRP and especially IL-6 could be used in the diagnosis of acute attack and monitoring the response to the treatment. However, increased cytokine levels in the passive period have supported the view that the subclinical inflammation has continued in these patient

Does ischaemia-modified albumin level predict clomiphene citrate resistant polycystic ovary syndrome patients?

This study aims to examine the role of ischaemic-modified albumin (IMA) in predicting clomiphene citrate (CC) resistance in patients with CC-resistant and CC-sensitive infertile polycystic ovary syndrome (PCOS). Sixty women patients admitted to the infertility clinic were evaluated. The patients were divided into two groups. Group 1 comprised 30 infertile PCOS patients with CC resistance; group 2 was the control group comprising 30 infertile PCOS patients with CC sensitivity. Serum IMA levels of PCOS patients with CC resistance were significantly higher than CC sensitivity patients (p < .001). The independent variables BMI and age effects were adjusted according to the logistic regression method with groups. Significant differences were observed between the two groups in the levels of IMA (p = .0005), HOMA-IR (p = .0045), insulin (p = .022), free testosterone (p = .0001) and total testosterone (p = .03) values. By using ROC curve analysis for IMA between study and control groups, cut off point of IMA was calculated as 0.505 U/mL, sensitivity was 80% and specificity was 63%. The area under the curve was 0.926. This shows us that more oxidative stress (OS) occurs in the CC-resistant group. As a reflection of OS in the follicular endocrine, microenvironment may be linked with impaired oocyte developmental competence and embryo quality in association with increased IMA, free testosterone, total testosterone, insulin and HOMA-IR levels.Impact statement What is already known on this subject? In previous studies, IMA was compared between PCOS and control groups. In this study, serum IMA levels were measured in infertile PCOS patients resistant to CC for the first time. What the results of this study add? Serum IMA levels were significantly higher in resistant infertile PCOS patients compared to the control group. This shows us that more OS occurs in the CC-resistant group. What the implications are of these findings for clinical practice and/or further research? IMA will be a guide for PCOS management in patients with CC-resistant PCOS

Maternal serum thiol/disulfide homeostasis in pregnancies complicated by fetal hypoxia

We aimed to evaluate maternal serum thiol/disulphide homeostasis in pregnancies complicated by fetal distress (FD). A total of 100 patients beyond the 34th week of pregnancy were included in this study, and they were divided into two groups. The study group included 50 patients who had been diagnosed with FD; the control group was composed of 50 patients who had shown no signs of FD and who had undergone an elective (previous) caesarean section (CS). The native thiol, total thiol and native thiol/total thiol (%) concentrations were lower in Group 1 patients than Group 2 patients (p < .001). The disulphide, disulphide/native thiol (%) and disulphide/total thiol (%) concentrations were higher in Group 1 patients than Group 2 patients (p < .001). This study suggests that maternal thiol/disulphide homeostasis is impaired in pregnancies complicated by FD.IMPACT STATEMENT What is already known about this subject? Oxidative stress (OS) has previously been investigated in FD. This study reports for the first time a new novel and automatic measurement method. What do the results of this study add? This study shows that the thiol balance shifts in the direction of disulphide in the cases of FD. What are the implications of these findings for clinical practice and further research? Thiol balance can be used for the timely diagnosis of FD
