Background: Oxidative stress may play an important role in rheumatoid arthritis (RA) etiopathogenesis. The thiol group is a very strong antioxidant. In this study, we aimed to investigate the presence of oxidative stress in patients with RA by evaluating thiol/disulfide homeostasis.

Material and methods: A total of 50 female RA patients and 50 healthy female controls were included in this study. Thiol and disulfide values were calculated utilizing novel methods.

Results: Native thiol (p<0.001) and total thiol (p<0.001) levels of RA patients were significantly lower compared to values in the control group. However, the disulfide (p<0.001) levels of RA patients were strongly higher than in healthy individuals. A negative correlation was found between thiol and disease activity score-28 among the patients, whereas a positive correlation was found between disulfide and disease activity score-28 among the patients.

Conclusion: We found that the thiol–disulfide rate deteriorated in RA patients, with the proportion of disulfide increasing. There is a strong correlation between the decrease in thiol levels, increase in disulfide levels and the disease activity scores.

Background. It is now suggested an association between non-alcoholic fatty liver disease (NAFLD) and the occurrence of coronary artery disease even in non-diabetic patients. We will determine the rate of NAFLD and its main determinants in non-diabetic patients undergoing coronary angiography.

Methods. This cross-sectional study was accomplished on 264 patients who were candidates for coronary angiography during the year 2016. Coronary angiography has been done to depict the presence or absence of coronary involvement, and the severity of coronary artery disease by determining the number of vessels involved and also the SYNTAX score. During 48 hours after coronary angiography, the patients underwent abdominal ultrasonography for detection of NAFLD.

Results. The overall prevalence of NAFLD in the patients was 72.3%. The prevalence of NAFLD in those with and without coronary involvement was 71.9% and 73.1% respectively, with no notable difference (p = 0.837). The mean SYNTAX score in the patients with and without NAFLD was 22.32 ± 11.10 and 21.75 ± 10.71 respectively with no difference (p = 0.702). According to the multivariable regression models, the presence of NAFLD could not predict the likelihood of coronary artery disease (OR = 0.879, p = 0.669) or its severity assessed by the SYNTAX score (beta = 0.046, p = 0.456). NAFLD grade was also not a determinant for coronary artery disease (OR = 1.139, p = 0.178) or its severity (beta = 0.058, p = 0.165).

Conclusion. It seems that the presence and grade of NAFLD may not be correlated with atherosclerotic involvement of coronary arteries and its severity in non-diabetic patients. Future large studies and trials could elucidate the independent role of fatty liver in nondiabetic non-alcoholic patients.

Introduction. Hypertrophic cardiomyopathy (HCM) is a disease with increased left ventricular (LV) wall thickness not solely explained by abnormal loading conditions, with great heterogeneity regarding clinical expression and prognosis. The aim of the present study was to collect data on HCM patients from different centres across the country, in order to assess the general characteristics and therapeutic choices in this population.

Methods. Between December 2014 and April 2017, 210 patients from 11 Romanian Cardiology centres were enrolled in the National Registry of HCM. All patients had to fulfil the diagnosis criteria for HCM according to the European Society of Cardiology guidelines. Clinical, electrocardiographic, imaging and therapeutic characteristics were included in a predesigned online file.

Results. Median age at enrolment was 55 ± 15 years with male predominance (60%). 43.6% of the patients had obstructive HCM, 50% non-obstructive HCM, while 6.4% had an apical pattern. Maximal wall thickness was 20.3 ± 4.8 mm (limits 15-37 mm) while LV ejection fraction was 60 ± 8%. Heart failure symptoms dominated the clinical picture, mainly NYHA functional class II (51.4%). Most frequent arrhythmias were atrial fibrillation (28.1%) and non-sustained ventricular tachycardia (19.9%). Mean sudden cardiac death risk score (SCD-RS) was 3.0 ± 2.3%, with 10.4% of the patients with high risk of SCD. However, only 5.7% received an ICD. Patients were mainly treated with beta-blockers (72.9%), diuretics (28.1%) and oral anticoagulants (28.6%). Invasive treatment of LVOT obstruction was performed in a small number of patients: 22 received myomectomy and 13 septal ablation. Cardiac magnetic resonance was reported in only 14 patients (6.6%).

Conclusions. The Romanian registry of HCM illustrates patient characteristics at a national level as well as the gaps in management which need improvement – accessibility to high-end diagnostic tests and invasive methods of treatment.

Introduction. Our research strategy was aimed at evaluating the possible implication of the type of factor VIII product administered as substitution treatment to haemophilia A patients in the occurrence of inhibitors and their consequences on the management.

Methods. Scientific articles from July 2015 to July 2017 were searched using the PubMed and PubMed Central databases. The used search terms included “haemophilia A”, “inhibitors”, “plasma-derived factor VIII” and “recombinant factor VIII”.

Results. The risk factors for inhibitors occurrence may be patients-related (genetic and nongenetic) and treatment-related. The possibility of a correlation between the increased purity of factor VIII given as substitution treatment and the occurrence of inhibitors is discussed in the light of literature data. Plasma-derived factor VIII is less immunogenic, but not entirely safe from the point of view of the possibility of transmitting biological agents. It is obvious that there is not enough plasma-derived factor VIII for the planet’s needs. Recombinant factor VIII products have revolutionized the treatment of patients with haemophilia A over the past 3 decades by the disappearance of transfusion-related infections and their complications. They are safer in terms of pathogens and the new long-acting factor VIII products are based on recombinant DNA technology.

Conclusion. Plasma-derived or recombinant factor VIII products must co-exist on the market for the benefit of haemophilic patients. Future solutions could be: less immunogenic factor VIII products, nonfactor replacement strategies, or bispecific antibody that mimics the function of coagulation factor VIII.

Tracheoesophageal fistula (TEF) is frequently congenital and requires surgical correction. TEF can also occur secondary to malignant esophageal tumors or benign diseases and these cases are managed by endoscopic means, such as closing the defect with metallic stents. Although esophageal injury can occur secondary to nonsteroidal anti-inflammatory drugs (NSAIDs), TEF secondary to chronic NSAIDs use has not been described in the literature.

We report the case of a male patient with refractory migraine and chronic use of NSAIDs, with a history of esophageal stenosis presenting with acute-onset total dysphagia. Upper gastrointestinal endoscopy and CT-scan revealed TEF located at 25 cm from the incisors. An esophageal stent was placed endoscopically, and 6 weeks a second stent was placed in a stent-in-stent manner to allow removal of both stents. Endoscopic control after the removal of the stents showed the persistence of the fistula, so a third stent was placed as a rescue therapy.

Against medical advice, the patient continued to use OTC painkillers and NSAIDs in large doses. Three months later, he was readmitted with total dysphagia and recent-onset dysphonia. CT scan revealed a new fistula above the already placed stent. A second metallic stent was endoscopically placed through the old stent to close the newly developed fistula. The patient was discharged on the third day with no complications and he remains well at 6 months follow-up.

Due to small cases studies, recurrent TEF remains a therapeutic challenge. Endoscopic therapy is usually an effective solution, but complex cases might require multiple treatment sessions.

Introduction. Combinations of gefitinib and radiotherapy have been observed to have synergistic and anti-proliferative effects on lung cancer in vitro. In the clinical setting, patients who presented with respiratory difficulties such as superior vena cava syndrome (SVCS), radiotherapy should be given immediately to address the emergency while waiting for the results of epidermal growth factor receptor (EGFR) mutation test. However, there has been no study that described the role of radio-therapy in Indonesian patients with EGFR-mutant lung adenocarcinoma.

Methods. This preliminary study aimed to evaluate the efficacy and toxicities of gefitinib and radiotherapy combination in lung adenocarcinoma patients in Persahabatan National Respiratory Referral Hospital, Jakarta, Indonesia. Subjects were consecutively recruited between January 2013 and December 2016.

Results. Thirty-one lung adenocarcinoma with EGFR mutations were enrolled. Most of them were male (51.61%) with a median age of 54.5 years old (range 38-70 years old). EGFR mutation characteristics were on exon 21 L858R point mutation (61.30%), exon 21 L861Q point mutation (16.12%) and exon 19 deletion (22.58%). Radiotherapy was given at doses between 30-60 Gy. Among these subjects, median progression-free survival (PFS) was 185 days (95%CI; 123.69 – 246.30), 1-year survival rate (1-yr) was 45.2%, and median overall survival (OS) was 300 days (95%CI; 130.94 – 469.06). There were no grade 3/4 hematological and nonhematological toxicities recorded. The most frequent grade 1 and 2 non-hematological toxicities were skin rash, diarrhea, and paronychia that might be related to tyrosine kinase inhibitor (TKI).

Conclusion. The combination of TKI with radiation may be considered in EGFR-mutant lung adenocarcinoma subjects.

Introduction. LIM Homeobox 6 (LHX6) encodes a LIM homeodomain transcription factor, contributes to tissue development and morphogenesis, and is mostly expressed in medial ganglionic eminence and odontogenic mesenchyme. However, it has been reported to play a role in cancer progression. This narrative review summarizes literatures that emphasize the molecular regulation of LHX6 in tumorigenesis.

Methods. In our systematic review, the PubMed database was used for the literature search using the combination of words that included “LHX6” and “cancer”. Relevant studies, including in vitro, in vivo experiments, and clinical studies, were analyzed in this review.

Results. We found evidences that LHX6 might be important in the inhibition of tumor cell proliferation, growth, invasion, and metastasis through the suppression of Wnt/β-catenin signaling pathway. Moreover, LHX6 is observed to be downregulated in certain types of cancer due to hypermethylation, thus hindering its tumor suppressing ability. In addition, hypermethylation can also be used to determine the stage of cancer development.

Conclusion. The downregulation of LHX6 expression might be responsible in promoting cancer progression. Future studies are necessary to investigate the potential of LHX6 as a novel cancer biomarker as well as its therapeutic implications towards certain types of cancer.

Background. We aimed to determine the relationship between endocan and cirrhotic cardiomyopathy.

Materials and methods. Patients with liver cirrhosis and no heart disease were included in a prospective observational study with liver disease decompensation and death as primary outcomes.

Results. 83 cirrhotic patients were included and 32 had cirrhotic cardiomyopathy. Endocan levels were significantly lower in patients with cirrhotic cardiomyopathy (5.6 vs. 7 ng/mL, p = 0.034). Endocan correlated with severity of cirrhosis, time to decompensation or death from liver disease (OR 4.5 95% CI 1.06-31.1).

Conclusion. Endocan is a promising biomarker of severity of cirrhosis and may help in the diagnosis of cardiac dysfunction in this population.
