Analysis of Risk Factors for the Development of Gestational Diabetes Mellitus in a Group of Romanian Patients.

Introduction: Gestational diabetes mellitus (GDM) is caused by numerous risk factors, the most common being old age, obesity, family history of diabetes mellitus, GDM, history of fetal macrosomia, history of polycystic ovary syndrome or treatment with particular drugs, multiple births, and certain races. The study proposed to analyze the risk factors causing GDM. Method: In the study, we included 97 pregnant women to whom there was an OGTT performed between weeks 24th and 28th of pregnancy, divided into two groups, with GDM and without GDM. The statistical analysis was performed with SPSS 26.0, the tests being statistically significant if p value < 0.05. Results: The favoring risk factors for the onset of GDM were analyzed, with statistically significant differences between the GDM group and the group without GDM related to the delivery age (32.39 ± 4.66 years old vs. 28.61 ± 4.71 years old), history of fetal macrosomia (13.7% vs. 0%), presence of GDM during previous pregnancies (7.8% vs. 0%), HBP before pregnancy (9.8% vs. 0%), gestational HBP (17.6% vs. 0%), glycemia value at first medical visit (79.37 ± 9.34 mg/dl vs. 71.39 ± 9.16 mg/dl), and weight gain during pregnancy (14.61 ± 4.47 kg vs. 12.48 ± 5.87 kg). Conclusions: Identifying the risk factors for the GDM onset has a special importance, implying an early implementation of interventional measures in order to avoid the onset of GDM and associated maternal and fetal complications.

Maternal and Fetal Metabolites in Gestational Diabetes Mellitus: A Narrative Review.

Gestational diabetes mellitus (GDM) is a major public health issue of our century due to its increasing prevalence, affecting 5% to 20% of all pregnancies. The pathogenesis of GDM has not been completely elucidated to date. Increasing evidence suggests the association of environmental factors with genetic and epigenetic factors in the development of GDM. So far, several metabolomics studies have investigated metabolic disruptions associated with GDM. The aim of this review is to highlight the usefulness of maternal metabolites as diagnosis markers of GDM as well as the importance of both maternal and fetal metabolites as prognosis biomarkers for GDM and GDM's transition to type 2 diabetes mellitus T2DM.

Triglyceride and glucose index: a useful tool for non-alcoholic liver disease assessed by liver biopsy in patients with metabolic syndrome?

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is associated with metabolic impairments, being a component of metabolic syndrome. Considering the involvement of fat accumulation and insulin resistance in NAFLD, triglyceride and glucose (TyG) index was proposed as a marker of NAFLD progression. The "gold standard" for the evaluation of liver lesions characteristic for NAFLD remains the liver biopsy. The aim of this study was to establish the links between TyG index, assessing insulin resistance, and histopathological lesions of liver samples obtained by liver biopsy in patients with metabolic syndrome. PATIENTS, MATERIALS AND METHODS: We conducted a study over a period of three years, including 113 adult patients with metabolic syndrome in whom hepatic disorders were assessed by liver biopsy and insulin resistance was evaluated by TyG index. RESULTS AND DISCUSSIONS: In our study, steatosis had a frequency of 92.03%, being identified 26 cases with mild steatosis, 48 with moderate steatosis and 31 with severe steatosis. Regarding non-alcoholic steatohepatitis (NASH), the frequency of this disorder in our study group was 29.2% in the subjects with liver steatosis, while liver fibrosis had a frequency of 53.09%. When we analyzed the relationships between TyG index and the presence of each type of lesion necessary for NASH diagnosis, we obtained statistically significant differences for the presence of hepatocyte ballooning (p=0.01) and a high statistically significance for the NAFLD activity score (NAS) (p<0.0001). CONCLUSIONS: TyG index is a facile tool that can be used to identify patients at risk for advanced NAFLD lesions evaluated by liver biopsy.

An unusual onset of Crohn's disease with oral aphthosis, giant esophageal ulcers and serological markers of cytomegalovirus and herpes virus infection: a case report and review of the literature.

Isolated esophageal ulcerations in Crohn's disease pose a great challenge in diagnosing and providing the correct treatment. We present the case of a 23-year-old woman with recurrent episodes of oral aphthosis, dysphagia, odynophagia and heartburn. Upper digestive endoscopy revealed an irregular mucosa with multiple ulcerations with irregular margins within the mid-esophagus. Immunoglobulin G (IgG) for cytomegalovirus and herpes virus were both positive. Four years after, she presented with the same symptoms and the involvement of ileo-colonic lesions, with pathological findings helped establish the Crohn's disease diagnosis. Crohn's disease represents an idiopathic chronic inflammatory gut disease, which can affect any part of the digestive tract. The onset by esophageal disease and no intestinal involvement is rare and challenging for a proper diagnosis.

Difficulty in positive diagnosis of ascites and in differential diagnosis of a pulmonary tumor.

Ascites is the most frequent complication of cirrhosis and occurs only when the portal hypertension has already installed but ascites is caused by neoplasms, heart failure, tuberculosis, pancreatic illnesses, as well as other kind of affections. We describe the case of a 67-year-old patient, a retired person, without significant personal or familial history, nonsmoker, infrequent alcohol and coffee consumer with following chief complaints at onset: loss of appetite, weight loss, serious physical asthenia, delayed intestinal transit, diffuse abdominal pain and increase of abdominal circumference. Initially was misdiagnosed with liver cirrhosis. After discharged from our Clinic, suspicion of diagnosis was mesothelioma as well as after first thoracoscopy and pleural biopsy performed in a Clinic of Thoracic Surgery. Several pleural fragments collected by biopsy were sampled for the histopathological exam. The stainings used were Hematoxylin-Eosin (HE) and Periodic Acid-Schiff (PAS) for the mucopolysaccharides. For the immunohistochemistry was used the labeled Streptavidin-Biotin (LSAB)-Horseradish peroxidase (HRP) method, as well as the antibodies: cytokeratin (CK) cocktail (AE1÷AE3), vimentin, calretinin, CK7, CK5÷6, CK20, epithelial specific antigen/epithelial cell adhesion molecule (Ep-CAM) (BerEP4), thyroid transcription factor-1 (TTF-1), E-cadherin, CDX2, carcinoembryonic antigen (CEA) and the Hector Battifora mesothelial antigen-1 (HBME-1). The aspect at immunohistochemistry establishes a positive diagnostic of poorly differentiated mucinous pulmonary adenocarcinoma, with "signet ring" cells. The rapid and accurate determination of the diagnostics will allow not only for a decrease in the expenses for inefficient treatments, but also for the guidance of the patients towards clinics or centers able to provide and supervise these treatments.

Correlation of clinical and biological evidence - a dominant therapeutic element of succeeding in ectopic pregnancy.

Tubal pathology, smoking, pelvic inflammatory disease, miscarriage, medical or surgical abortion, usage of intrauterine devices (IUDs) for women with salpingitis latent injuries, older than 40 years, are risk factors for ectopic pregnancy. The objective of this study concerns the correlation of the clinical and biological evidence for the early diagnosis of the ectopic pregnancy and, as soon as possible, for the estimation for eventual risk of complications that may appear. The transvaginal ultrasound test, minimal increases in serum beta-human chorionic gonadotropin (ß-hCG) dynamics and blood counts are investigations of choice in achieving our objective. Overcoming ß-hCG critical level (>1198 IU÷mL), the decrease of platelets and changes in platelet constants announce the imminent risk of ectopic pregnancy rupture and the need to take a quick decision on the course of treatment.

Determination of VEGFR-2 (KDR) 604A>G Polymorphism in Pancreatic Disorders.

Pancreatic disorders have a high prevalence worldwide. Despite the fact that screening methods became more effective and the knowledge we have nowadays about pancreatic diseases has enhanced, their incidence remains high. Our purpose was to determine whether single nucleotide polymorphism (SNP) of VEGFR-2/KDR (vascular endothelial growth factor receptor 2/kinase insert domain receptor) influences susceptibility to develop pancreatic pathology. Genomic DNA was extracted from blood samples collected from patients diagnosed with acute pancreatitis (n = 110), chronic pancreatitis (n = 25), pancreatic cancer (n = 82) and healthy controls (n = 232). VEGFR-2 (KDR) 604A>G (rs2071559) polymorphism frequency was determined with TaqMan allelic discrimination assays. Statistical assessment was performed by associating genetic polymorphism with clinical and pathological data. In both pancreatic disorders and healthy control groups the polymorphism we studied was in Hardy-Weinberg equilibrium. Association between increased risk for pancreatic disorders and studied polymorphism was statistically significant. KDR 604AG and AG + GG genotypes were more prevalent in acute pancreatitis and pancreatic cancer patients than in controls. These genotypes influence disease development in a low rate. No association was found between chronic pancreatitis and KDR 604AG and AG + GG genotypes. In Romanian cohort, we found an association between the KDR 604A→G polymorphism and acute pancreatitis and pancreatic cancer. Carriers of the -604G variant allele were more frequent among acute pancreatitis and pancreatic cancer than among controls, suggesting that KDR 604G allele may confer an increased risk for these diseases. In the future, more extensive studies on larger groups are necessary, in order to clarify the role of VEGFR2 polymorphisms in pancreatic pathology.

The association between chronic pancreatitis and the iNOS-2087A>G polymorphism.

INTRODUCTION: Chronic pancreatitis is morphologically characterized by ductal dysplasia, breeding grounds for the proliferation of the ductal cells, the degenerative changes in pancreatic acinar cells and fibrosis, and it is defined on the basis of the clinical, morphological and functional criteria. AIM: The aim of our study is to examine the existence of a possible correlation between the iNOS-2087A>G polymorphism and chronic pancreatitis by means of the genetic analysis. MATERIAL AND METHOD: We have conducted the study at the Gastroenterology Clinic and the Research Center of Gastroenterology and Hepatology of the University of Medicine and Pharmacy, Craiova, between March 2015 - September 2016. The study had a prospective character. Both for the 58 patients diagnosed with chronic pancreatitis and for the 132 patients in the witness group, the biological material was represented by blood, (around 2.5 - 5 milliliters of venous blood) let on EDTA and kept at 4°C up to the separation of the DNA molecule. All the patients were genotyped for the iNOS - 2087A>G polymorphism, by means of the Real Time PCR technique with TaqMan probes. RESULTS: Analysing the prevalence of the iNOS genotypes within the study group and witness group, we have noticed that, statistically speaking, there are no significant differences between the two groups. CONCLUSION: As a conclusion, in the study lot we can sustain that the risk of developing chronic pancreatitis is not increased by the presence of the iNOS-2087A>G polymorphism.

Correlations between endothelial cell markers CD31, CD34 and CD105 in colorectal carcinoma.

PURPOSE: Colorectal carcinoma is an important cause of mortality worldwide. The fact that tumor growth is dependent on angiogenesis has supported researches for new prognostic parameters and the development of novel therapeutic strategies. Accordingly, we sought to evaluate angiogenesis quantitatively by assessing microvessel density in colorectal cancer. MATERIALS AND METHODS: The blood vessels stained with CD31, CD34 and CD105 were counted, and we reported their number per square millimeter in order to obtain microvascular density (MVD). Then, we aimed at comparing the performance of three endothelial cell markers (CD31, CD34, and CD105) on formalin-fixed tissues from 58 patients diagnosed with colorectal cancer. RESULTS: Following the comparison of the average effective vessels marked with the three markers, Student's t-test showed that the mean number of blood vessels marked with CD34 is higher than the blood vessels marked with CD31 and CD105. A significant difference that has been registered between the three levels of the T stage was found in the patients in our study, in terms of value marker CD105, ANOVA p=0.049, which returns to a value <0.05. Quick time decreases the pT stage, the observed differences being close to statistical significance. However, the result of ANOVA test does not allow us to say that differences can be generalized and not just a particular result, valid only for the study group, p=0.061 >0.05. There is a significant difference between patients with stage T, in terms of value: hemoglobin (ANOVA p<0.001), hematocrit (ANOVA p<0.001), mean corpuscular volume (MCV) (ANOVA p<0.001), mean corpuscular hemoglobin (MCH) (ANOVA p=0.002 <0.01 - significant difference with 99% confidence). By calculating the Pearson's correlation coefficient for the relationship CD31-CD105, we obtained a value r=0.440, which corresponds to p=0.0013 <0.05, indicating a statistically noteworthy direct correlation between the two factors. CONCLUSIONS: CD31 marker increases simultaneously with the CD105, in the cases analyzed throughout the present study. The ability of tumors to maintain a high vascular blood density in their inner portions may represent a reliable parameter to evaluate tumor angiogenesis and a finding relevant for future development of therapeutic angiogenesis strategies.

Histological factors that predict the liver fibrosis in patients with chronic hepatitis C.

In chronic hepatitis, pathologies reveal a prominent inflammatory infiltrate portal consisting mostly of lymphocytes and plasma cells invading the portal spaces, although one can also identify macrophages, neutrophils or eosinophils. In all the forms of chronic hepatitis, fibrosis starts in the portal area, namely periportally, subsequently extends towards the lobules to the central veins, causing septa, followed by fibrosis. We studied 52 patients with chronic hepatitis C, who underwent a hematological, biochemical, virological and histopathological investigation. We found that the severity degree of the portal inflammation was in direct relation to the hepatitis activity index (HAI) and to the degree of fibrosis. The portal inflammation is dependent to the degree of fibrosis. The degree of inflammation significantly changes the distribution of cases with different degrees of fibrosis (chi-square p=0.00011 <0.001). Periportal inflammation, periportal necrosis and focal necrosis are the morphological aspects of the necroinflammatory process best correlated to the occurrence and development of fibrosis.

Lymph node tuberculosis after melanoma treatment - sometimes the patient is lucky.

Tuberculosis (TB) is considered a pulmonary disease that can however disseminate to other organs through hematogenous dissemination following primary TB infection. Evolution of the disease can either be precocious, before healing of the primary infection, or late after primary infection, due to reactivation of initial lesions usually because of simultaneous immunosuppressive factors such as diabetes, renal disease, hepatic disease or different type of immunosuppressing treatments. Rare cases when tuberculosis and cancer are diagnosed at the same time create diagnostic difficulties and therapeutic challenges. We present the case of an asymptomatic 52-year-old female that was diagnosed "by chance, at the right moment" with a form of skin melanoma on the right forearm, for which she received a rather well tolerated cytostatic treatment. At the end of this treatment, she was also investigated for a breast mass that proved to be benign; however, enlarged lymph nodes were discovered in the right armpit were discovered upon further investigation. One of the lymph nodes was surgically removed, as first suspicion was of a metastasis from the skin melanoma. However, it was lymph node tuberculosis therefore anti-tuberculosis treatment was initiated. The patient tolerated the treatment with minor side effects. On few occasions, a patient can be diagnosed with incipient stages of skin melanoma and even more rarely the same patient is diagnosed and treated prematurely for lymph node tuberculosis. Sometimes, a successful outcome needs an organized and well-educated patient and a little luck.

Hepatocellular carcinoma and metabolic diseases - histological perspectives from a series of 14 cases.

Hepatocellular carcinoma (HCC) represents a major health burden, as curative methods only apply to a select small portion of the affected population. Screening programs are ineffective in the absence of established underlying conditions such as viral hepatitis or alcohol abuse resulting in liver cirrhosis. Thus, overweight or obese, diabetic patients as well as non-alcoholic fatty liver disease (NAFLD) cases are often overlooked as potential candidates for HCC development. Current diagnostic methods for HCC are restricted to non-invasive imaging tests; however, the need for accurate predictive or therapeutic markers make histological studies a necessity; the latest guidelines and recommendations demand an increased effort in obtaining pertinent data from immunohistochemical investigations. Our aim was to retrospectively evaluate a series of patients with common symptoms and manifestations of metabolic syndrome who underwent liver biopsy after imaging revealed suspicious liver masses. We describe the major findings of both common histological evaluation and microvessel density evaluated by positive CD34 immunostaining.
