Immune Responses of Healthy Pregnant Women following an Elective Cesarean Section: Effects of Anesthetic Procedures. Diagnostics (Basel) 2024; 14:880. [PMID: 38732295 PMCID: PMC11083323 DOI: 10.3390/diagnostics14090880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Revised: 04/19/2024] [Accepted: 04/22/2024] [Indexed: 05/13/2024] Open
Abstract
A weakened immune system and more inflammatory cytokines being released are possible effects of the surgical stress that a cesarean section induces. This kind of reaction, in addition to the altered reaction to catecholamines, has the potential to significantly affect the immune system of the mother and the patients' general postoperative course. This prospective study compared the plasma levels of catecholamines and cytokines in healthy pregnant patients having cesarean sections under spinal anesthesia versus general anesthesia. A total of 30 pregnant women undergoing elective cesarean sections were divided into two groups: 15 who received general anesthesia (GA) and 15 who received spinal anesthesia (SA). Blood samples were collected from all subjects before anesthesia induction (pre-OP), 6 h postoperatively (6 h post-OP), and 12 h (12 h post-OP), to measure levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), IL-8, IL-4, IL-10, norepinephrine (NE), and epinephrine (EPI). When we compared the two groups, we discovered that only IL-6 and IL-4 had significantly higher levels pre-OP, whereas all studied cytokines exhibited an increase in the GA versus SA group at 6 and 12 h post-OP. In the case of catecholamines, we discovered that serum levels are positively related with pro-inflammatory or anti-inflammatory cytokines, depending on the time of day and type of anesthetic drugs. Compared to SA, GA has a more consistent effect on the inflammatory response and catecholamine levels. The findings of this study confirm that the type of anesthesia can alter postoperative immunomodulation to various degrees via changes in cytokine and catecholamine production. SA could be a preferable choice for cesarean section because it is an anesthetic method that reduces perioperative stress and allows for less opioid administration, impacting cytokine production with proper immunomodulation.

Abstract
BACKGROUND Acute fatty liver disease in pregnancy (AFLP) is a low-incidence condition that usually affects women in the third trimester of pregnancy or the early postpartum period. This article reviews recent advances in the diagnosis and treatment of AFLP with pancreatitis in pregnancy induced by in vitro fertilization (IVF). CASE REPORT A rare case of AFLP and pancreatitis occurred in a pregnant woman with an IVF-induced twin pregnancy delivered by cesarean section. Diagnosis of this condition is difficult, and delay in accurate diagnosis and timely and appropriate treatment can lead to serious complications such as acute pancreatitis or extensive damage to multiple organs and systems, which can have significant consequences. The main therapeutic approach was the rapid administration of drugs accompanied by therapeutic measures to support liver function and pancreatic complications. CONCLUSIONS We would like to reemphasize the importance of multidisciplinary management and rapid intervention in AFLP with acute pancreatitis after IVF.

Longitudinal 8-Epi-Prostaglandin F2-Alpha and Angiogenic Profile Mediator Evaluation during Pregnancy in Women with Suspected or Confirmed Pre-eclampsia. Biomedicines 2024; 12:433. [PMID: 38398035 PMCID: PMC10886743 DOI: 10.3390/biomedicines12020433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 01/31/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024] Open
Abstract
Background: In this exploratory study, we aimed to evaluate the dynamics of angiogenic [soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), soluble Endoglin (sEng), and sFlt-1/PlGF, PlGF/sFlt-1, and sEng/PlGF ratios] and oxidative stress [8-epi-prostaglandin F2 alpha (8-epi-PGF2α) and 8-epi-PGF2α/PlGF ratio] mediator levels in women with suspected or confirmed pre-eclampsia (PE) at least two times during pregnancy. We also wanted to identify the possible correlations between 8-epi-PGF2α and angiogenic mediator levels at the time of inclusion of pregnant women. Methods: We included 40 pregnant women with suspected or confirmed PE, with a mean age of 29 years (range between 18 and 41 years) and gestational age between 18 and 28 weeks at inclusion in this study. The Enzyme-Linked Immunosorbent Assay (ELISA) method to measure the levels of serum angiogenic and oxidative stress mediators was used. Results: The evaluation of baseline sFlt-1/PlGF ratios using a cut-off of 38 suggested that 25 pregnant women had a sFlt-1/PlGF ratio of >38 (sFlt-1/PlGF ratio of >38 group) and 15 had a sFlt-1/PlGF ratio of ≤38 (sFlt-1/PlGF ratio of ≤38 group). The increases in sFlt-1/PlGF ratio in the sFlt-1/PlGF ratio of >38 group were caused by both an increase in sFlt-1 (2.04-fold) and a decrease in PlGF levels (2.55-fold). The 8-epi-PGF2α median levels were higher in the sFlt-1/PlGF ratio of >38 group (1.62-fold). During follow-up after pregnancy, we observed that the mean values of sFlt-1 and sEng and the median values of 8-epi-PGF2α and sFlt-1/PlGF, sEng/PlGF, and 8-epi-PGF2α/PlGF ratios increased directly proportional to gestational age for each measurement time until delivery in both groups. For five women who had a sFlt-1/PlGF ratio ≤38 at inclusion, sFlt-1/PlGF ratio was observed to increase to >38 later in pregnancy. We observed that, in the sFlt-1/PlGF ratio >38 group, baseline 8-epi-PGF2α levels better correlated with angiogenic mediator levels. Conclusions: Our study shows that 33.33% of pregnant women evaluated for suspected or confirmed PE with a sFlt-1/PlGF ratio of ≤38 displayed a rise in sFlt-1/PlGF ratio in subsequent weeks. In addition, together with angiogenic mediators, 8-epi-PGF2 α can be utilized as an independent predictor factor to help clinicians identify or predict which pregnant women will develop PE.

Interrelation of Hypoxia-Inducible Factor-1 Alpha (HIF-1 α) and the Ratio between the Mean Corpuscular Volume/Lymphocytes (MCVL) and the Cumulative Inflammatory Index (IIC) in Ulcerative Colitis. Biomedicines 2023; 11:3137. [PMID: 38137357 PMCID: PMC10741094 DOI: 10.3390/biomedicines11123137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 11/20/2023] [Accepted: 11/23/2023] [Indexed: 12/24/2023] Open
Abstract
We intended to investigate the presence and medical application of serum hypoxia-inducible factor-1 alpha (HIF-1α) along with the already known systemic inflammatory markers and the new one's inflammatory indices, the proportion of mean corpuscular volume and lymphocytes (MCVL) and the cumulative inflammatory index (IIC), for patients with ulcerative colitis (UC). We sought to establish correlations that may be present between the serum levels of HIF-1α and these inflammatory indices, as well as their relationship with disease activity and the extent of UC, which can provide us with a more precise understanding of the evolution, prognosis, and future well-being of patients. Serum samples were collected from 46 patients diagnosed with UC and 23 controls. For our assessment of the serum levels of HIF-1α, we used the Enzyme-Linked Immunosorbent Assay (ELISA) technique. Thus, for HIF-1α we detected significantly higher values in more severe and more extensive UC. When it came to MCVL and IIC, we observed statistically significant differences between the three groups being compared (Severe, Moderate, and Mild). Our study highlighted that HIF-1α correlated much better with a disease activity score, MCVL, and IIC. With MCVL and IIC, a strong and very strong correlation had formed between them and well-known inflammation indices. By examining the ROC curves of the analyzed parameters, we recognized that TWI (accuracy of 83.70%) provides the best discrimination of patients with early forms of UC, followed by HIF-1α (73.90% accuracy), MCVL (70.90% accuracy), and PLR (70.40%). In our study, we observed that HIF-1α, MCVL, and PLR had the same sensitivity (73.33%) but HIF-1α had a much better specificity (60.87% vs. 58.70%, and 54.35%). Also, in addition to the PLR, HIF-1α and MCVL can be used as independent predictor factors in the discrimination of patients with early forms of UC.

Association between Serum 8-Iso-Prostaglandin F2α as an Oxidative Stress Marker and Immunological Markers in a Cohort of Preeclampsia Patients. Life (Basel) 2023; 13:2242. [PMID: 38137843 PMCID: PMC10745027 DOI: 10.3390/life13122242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 11/07/2023] [Accepted: 11/21/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND We aimed to analyze the presence and clinical use of serum 8-iso-prostaglandin F2-alpha (8-iso-PGF2α) as an oxidative stress marker and some inflammatory status biomarkers (tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), IL-10, high-sensitivity C-reactive protein (hs-CRP), and pentraxin-3 (PTX3)) for patients with preeclampsia (PE). METHODS Sixty pregnant women, including thirty diagnosed with PE and thirty who were healthy (NP), were included in this study. For the assessment of serum levels of biomarkers, we used the Enzyme-Linked Immunosorbent Assay (ELISA) technique. RESULTS Our preliminary study showed that the expression level of serum 8-iso-PGF2α in the PE group was higher than in the PE after delivery (PE-AD) group (742.00 vs. 324.00 pg/mL, p < 0.0001). Groups of preeclamptic patients (PE + PE-AD) expressed significantly elevated levels for all of the assessed inflammatory mediators as compared to NP. Significant strong positive correlations with 8-iso-PGF2α levels were found for systolic blood pressure (SBP), and TNF-α (Spearman's rho = 0.622, p-value = 0.020 and rho = 0.645, p-value = 0.002, respectively). Our study demonstrates that 8-iso-PGF2α and PTX3 have the greatest diagnostic value for pregnant women with PE. CONCLUSIONS 8-iso-PGF2α and PTX3 can be used as independent predictor factors, along with already-known cytokines, that could represent a prophylactic way to help clinicians identify or predict which pregnant women will develop PE.

MMP-13, VEGF, and Disease Activity in a Cohort of Rheumatoid Arthritis Patients. Diagnostics (Basel) 2023; 13:diagnostics13091653. [PMID: 37175043 PMCID: PMC10184131 DOI: 10.3390/diagnostics13091653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/04/2023] [Accepted: 05/05/2023] [Indexed: 05/15/2023] Open
Abstract
Identifying certain serum biomarkers associated with the degree of rheumatoid arthritis (RA) activity can provide us with a more accurate view of the evolution, prognosis, and future quality of life for these patients. Our aim was to analyze the presence and clinical use of matrix metalloproteinase-13 (MMP-13), along with vascular endothelial growth factor (VEGF) and well-known cytokines such as tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6) for patients with RA. We also wanted to identify the possible correlations between MMP-13 and these serological markers, as well as their relationship with disease activity indices, quality of life, and ultrasonographic evaluation. For this purpose, we analyzed serum samples of 34 RA patients and 12 controls. In order to assess serum concentrations for MMP-13, VEGF, TNF-α, and IL-6, we used the enzyme-linked immunosorbent assay (ELISA) technique. Our results concluded that higher levels of MMP-13, VEGF, TNF-α, and IL-6 were present in the serum of RA patients compared to controls, with statistical significance. We furthermore identified moderately positive correlations between VEGF, MMP-13, and disease activity indices, as well as with the ultrasound findings. We also observed that VEGF had the best accuracy (97.80%), for differentiating patients with moderate disease activity. According to the data obtained in our study, that although MMP-13, TNF-α and C-reactive protein (CRP) have the same sensitivity (55.56%), MMP-13 has a better specificity (86.67%) in the diagnosis of patients with DAS28(4v) CRP values corresponding to moderate disease activity. Thus, MMP-13 can be used as a biomarker that can differentiate patients with moderate or low disease activity. VEGF and MMP-13 can be used as additional parameters, along with TNF-α and IL-6, that can provide the clinician a better picture of the inflammatory process, disease activity, and structural damage in patients with RA. Our data can certainly constitute a start point for future research and extended studies with multicenter involvement, to support the selection of individualized and accurate therapeutic management strategies for our patients.

The Role of Uterine Artery Doppler in the Second and Third Trimesters for Prediction of Preeclampsia and Fetal Growth Restriction Developed as a Consequence of Placental-Mediated Diseases. CURRENT HEALTH SCIENCES JOURNAL 2023; 49:251-256. [PMID: 37779836 PMCID: PMC10541058 DOI: 10.12865/chsj.49.02.251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Accepted: 04/07/2023] [Indexed: 10/03/2023]
Abstract
Placenta-mediated pregnancy disorders represent a disease that includes preeclampsia (PE) and the birth of small for gestational age (SGA) children, these conditions increase the risk of mortality and morbidity both maternal and fetal/neonatal, in the short and long-term. METHODS The prospective study included 106 patients in whom ultrasound Doppler scans of uterine artery (UtA) were performed in the 2nd trimester between 20.0-23.6 weeks of gestation and the 3rd trimester between 28.0-32.6 weeks of gestation. RESULTS In the second trimester, the average of the UtA-PI percentiles was statistically significant (p<0.05) in correlation with PE and SGA, as in the third trimester. Statistically significant (p<0.05) was also the correlation of UtA-PI >95 percentile with the development of PE and SGA. On the other hand, the present notch, in the two trimesters studied, analyzed as a single index, did not present a statistically significant association (p>0.05). CONCLUSIONS The results of our study showed that UtA-PI Doppler is the best predictor of preeclampsia considering the association of intrauterine growth restriction, as most studies have found.

Abstract
The objective of the cross-sectional study was to assess periodontal and implant health condition among individuals diagnosed with Sjogren's Syndrome (SS), taking into account the clinical circumstances associated with this patient population. The clinical parameters employed to evaluate the periodontal status of both natural teeth and implants included: periodontal probing depth (PPD) measured at six sites per tooth/implant, clinical attachment level (CAL), bleeding on probing index (BOP), plaque index (PLQ). Gingival crevicular fluid samples were collected for interleukin-16 level evaluation. After clinical and immunological assessment of the study and control groups, the data was centralized, compiled and submitted for statistical analysis. In all four types of assessed periodontal parameters, there were statistically significant differences between the SS patients with no dental implants and the other test (SSi) and control groups (Cni and Ci). Nevertheless, in SS patients with dental implants, plaque levels were similar to that of controls. In addition, other periodontal parameters (PPD, BOP and CAL) were similar in SS patients with dental implants and controls, with no statistically significant difference. The highest GCF IL-6 levels were found in SS patients with no dental implants, the differences to the other study and control groups being statistically significant. In patients with SS and dental implants, there were no statistically significant differences to the other groups. Individuals diagnosed with Sjogren's Syndrome (SS) exhibit a less favorable periodontal condition compared to controls without SS. Notably, SS patients who undergo dental implant procedures demonstrate an improvement in their periodontal status. This highlights the importance of proactive and ongoing dental and periodontal surveillance for SS patients, aiming to decrease the risk of developing periodontal diseases.

Abstract
OBJECTIVE Evaluation of Intraplacental Villous Artery Doppler (IPVA) as a predictive factor compared to umbilical artery (UA) Doppler in placenta-mediated disease (PMD). METHODS This prospective study included a group of 106 pregnant women, of which 76 patients constituted the PMD group: preeclampsia (PE) and small for gestational age (SGA), and 30 pregnant women constituted the control group. IPVA and UA Doppler evaluation was performed in 2 pregnancy periods: 20.0-23.6 weeks, and 28.0-32.6 weeks of gestation. RESULTS From the study of maternal characteristics and risk factors for the presented pathology, we found that no studied risk factor was statistically involved in the evolution toward PMD during pregnancy. In the control group, we noticed a decrease in IPVA PI and RI, along with an increase in gestational age, while in the PMD group, these indices increased. Both in the 2nd and the 3rd trimester, we had a significant statistical difference between the two groups (p<0.001). Regarding the degree of prediction of the changes that occurred at this level, we found a good statistical correlation. A higher degree of positive predictability is noted, for IPVA-PI, but also for UA-PI, but with better sensitivity (72.27%) for UA PI in the 2nd trimester. CONCLUSIONS We can conclude that both Doppler measurements, IPVA and UA can be used to evaluate and detect pregnancy complications that belong to PMD, preeclampsia, and/or fetal growth restriction.

Abstract
Periodontitis is characterized by low-grade inflammation of the periodontal tissues, the structures that support and connect the teeth to the maxilla and mandible. This inflammation is caused by the accumulation of subgingival bacterial biofilm and gradually leads to the extensive damage of these tissues and the consequent loss of teeth. Hepatitis B is a major global health concern; infection with the hepatitis B virus causes significant inflammation of the liver and the possibility of its gradual evolution to cirrhosis. Hepatitis D, caused by infection with the delta hepatitis virus, is manifest only in patients already infected with the type B virus in a simultaneous (co-infected) or superimposed (superinfected) manner. The dental and periodontal status of patients with hepatitis B/D could exhibit significant changes, increasing the risk of periodontitis onset. Moreover, the progression of liver changes in these patients could be linked to periodontitis; therefore, motivating good oral and periodontal health could result in the prevention and limitation of pathological effects. Given that both types of diseases have a significant inflammatory component, common pro-inflammatory mediators could drive and augment the local inflammation at both a periodontal and hepatic level. This suggests that integrated management of these patients should be proposed, as therapeutical means could deliver an improvement to both periodontal and hepatic statuses. The aim of this review is to gather existing information on the proposed subject and to organize significant data in order to improve scientific accuracy and comprehension on this topic while generating future perspectives for research.

Abstract
Maternal obesity is associated with increased maternal and fetal morbidity and mortality, with an increased risk of gestational diabetes mellitus (GDM) and preeclampsia (PE). This prospective study histopathologically analyzes the placentas obtained from 34 pregnant obese women studied between October 2016 and May 2020. The 10 cases of term placentas from obese pregnancies with GDM and the 12 cases with PE were examined by the Hematoxylin–Eosin (HE), Masson’s trichrome (MT) and Periodic Acid–Schiff–Hematoxylin (PAS–H) classical stainings, and by the immunohistochemical evaluation and compared to placentae from uncomplicated term obese pregnancies (12 cases). We did not meet placental histopathological (HP) abnormalities that we could classify as characteristic only for the state of obese pregnancy, but we did find placental changes associated with PE and GDM, in the context of obese pregnancy. In the case of association with PE, there were common lesions, manifested by intra- and perivillous fibrinoid deposition, calcification, and placental infarction area, to which were added numerous syncytial knots. In the case of obese pregnancy associated with GDM, we found, in addition to common placental lesions of obesity, intravillositary vascular edema and in the terminal villi appearing chorangiosis. This study revealed a number of HP changes that occur in maternal obesity, even in uncomplicated obese pregnancies. A characteristic of obese pregnancies associated with PE was the presence of numerous syncytial knots, and in obese pregnancies associated with GDM, the most common HP lesion was placental chorangiosis. Certainly, we cannot conclude that these HP lesions are specific to a particular pathology, but they belong primarily to the status of maternal obesity.

Abstract
OBJECTIVE Demonstration of the predictive capacity of Doppler Uterine Artery (UtA) on preterm birth (PB) by serial measurement at various ages of pregnancy. METHODS The prospective study included a group of 116 pregnant women, of whom 85 gave birth prematurely and 31 pregnant women gave birth at term, constituting the control group. UtA Doppler measurement was performed by the abdominal approach. Quantitative wave evaluations were performed by the pulsatility index (PI), the systole/diastole ratio (S/D), as well as the qualitative analysis of the flow rate waveform (notch). UtA Doppler evaluation was performed in 3 pregnancy periods: 18.0-22.6 weeks, 28.0-31.6 weeks, and 32.0-35.6 weeks. RESULTS Only at the third examination, at 32.0-35.5 weeks of gestation, was there a statistically significant difference between the S/D-UtA ratio and PI-UtA correlated with the risk of premature birth (p<0.05). Although there was an association between UtA Doppler and late preterm birth, the predictive ability was low. Also, UtA Doppler was not statistically significant for preterm birth before 32 weeks of gestation. CONCLUSIONS Although we did not find a statistical association between second-trimester UtA Doppler and preterm birth, we do suggest a closer look at women with abnormal UtA Doppler in the second trimester. We believe that, according to the results obtained, UtA Doppler can predict especially iatrogenic premature birth depending on the prediction of the most severe complications, severe preeclampsia, and SGA.

Abstract
Septic arthritis (SA) is a less common joint pathology with potentially fatal outcome. It is considered a medical emergency, in which prompt diagnosis and differentiation of bacterial etiology is essential for appropriate management. The knee is the most prevalent site for SA (~50% of cases), followed by hip, shoulder, and elbow. Early intervention requires an accurate diagnosis and imaging techniques enable both a positive diagnosis, as well as arthrocentesis and liquid analysis, the “gold standard” criteria. We report the case of a 70-year-old patient, with history of rheumatoid arthritis (RA), diabetes mellitus (DM) and persistent left malum perforans in the last year, with development of a severe and debilitating Staphylococcus aureus-related SA of the left ankle, which posed significant therapeutic challenges. He developed a plantar lesion at the ball of the left foot, in the past one year, which was labeled as malum perforans in the setting of DM. Musculoskeletal ultrasound was the primary imaging technique used to define the location and extent of the infectious process. Cultures drawn from the tissue were positive for S. aureus. After an antibiotic course, the apparent infectious features were remitted but the long-lasting open wound failed to improve. Antibiotic therapy was initiated in accordance with culture sensibility tests but short- and long-term outcome was unfavorable with both treatment unresponsiveness and comorbidity burden posing considerable difficulties. The association and interrelation between different comorbidities (such as hypertension, diabetes, or obesity), chronic systemic inflammation (e.g., C-reactive protein level, disease activity), and RA medication is sometimes difficult to understand and to address in daily practice, and this case report highlights multiple toils encountered in a SA patient with RA on immunosuppressive therapy and complicated DM.

Abstract
Next to A and B antigens, agglutinogen D exhibits the highest immunogenicity. Following the transfusion of D-positive red blood cells (RBCs), almost 80% of D-negative recipients develop anti-D antibodies (Abs). Subsequently, anti-D immunization further promotes the synthesis of Abs towards other blood group antigens in or outside the Rh system. The D antigen is also involved in 95% of cases of hemolytic disease of the newborn. Transfusions, hemotherapy, grafts, and obstetric history (abortions, ectopic pregnancy, births) are all risk factors for Rh isoimmunization. In the case of ABO compatibility between mother and fetus, Rh-positive fetal RBCs that have reached the maternal bloodstream are not destroyed by group agglutinins, and Rh antigenic sites are not hidden by the maternal immune system. But a Rh-negative mother with a homozygous Rh-positive husband will certainly have a Rh-positive fetus. As it has an irreversible evolution, the Rh isoimmunization once installed cannot be influenced in the sense of decreasing the Ab titer, therefore, injectable globulin has no effect. A particular case was that of a newborn with Rh system incompatibility associated with hereditary spherocytosis The clinical balance at birth reflects the severe jaundice of the female newborn of 3140 g, gestational age 38∕39 weeks, extracted by lower-segment transverse Caesarean section, with a double loop nuchal cord, Apgar score 8. Because the jaundice was severe and atypical (face and upper chest), we considered the possibility of coexistence of hemolytic disease of the newborn by Rh blood group incompatibility associated with hereditary spherocytosis, as it turned out to be true and mentioned. Changes in genes encoding proteins in the structure of the RBC membrane have amplified hemolysis induced by maternal-fetal isoimmunization in the Rh system. Massive hemolysis accentuated by congenital spherocytosis, confirmed later, imposed blood transfusion and dynamic monitoring.

Non-Surgical Periodontal Therapy Could Improve the Periodontal Inflammatory Status in Patients with Periodontitis and Chronic Hepatitis C. J Clin Med 2021; 10:jcm10225275. [PMID: 34830557 PMCID: PMC8619210 DOI: 10.3390/jcm10225275] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 11/08/2021] [Accepted: 11/09/2021] [Indexed: 12/15/2022] Open
Abstract
Non-surgical periodontal therapy (NSPT) is the first essential step for the management of any periodontitis patient. This study aims to evaluate the impact of NSPT on pro-inflammatory mediators’ regulation and on clinical parameters in periodontitis patients who suffer from chronic hepatitis C. At baseline, selected patients were clinically evaluated for their periodontal status. A subsequent quantitative assessment of C-reactive protein and pentraxin-3 in samples of gingival fluid was performed by Enzyme-Linked Immunosorbent Assay (ELISA). Afterwards, NSPT was performed. Three months after NSPT, the clinical and ELISA assessments were repeated. The results show an improvement of the clinical parameters in periodontitis patients at the three-month recall. In chronic hepatitis C patients with periodontitis, the gingival fluid levels of pro-inflammatory markers reduced significantly. The targeted markers also expressed significant correlations with the clinical parameters used for the assessment of periodontitis’ severity. The results suggest that, while chronic hepatitis C patients exhibited a more negative periodontal status at baseline as compared to non-hepatitis ones, NSPT is effective in decreasing the local periodontal inflammatory reaction and in proving the periodontal status of this type of patients. Given the limitation of the study, periodontal screening and NSPT should be included in the integrated therapeutical approach of chronic hepatitis C patients, for its impact on the local inflammatory response.

Abstract
BACKGROUND Preeclampsia (PE), one of the classes of hypertensive pregnancy disorders, is one of the three causes of maternal morbidity and mortality worldwide. The angiogenic and anti-angiogenic factors are useful markers in predicting and diagnosing PE. AIM This study aims to detect and measure the serum level of some biomarkers [hypoxia-inducible factor-1 subunit alpha (HIF-1A), vascular endothelial growth factor (VEGF), interferon-gamma-inducible protein of 10 kDa (IP-10), matrix metalloproteinase-13 (MMP-13)] in patients with PE and their correlation with the severity of the disease, to find a good predictor for PE. PATIENTS, MATERIALS AND METHODS This prospective study aims to monitor 48 pregnant women who address obstetric consultation and who present risk factors for PE, and a control group with characteristics similar to the study group. Patients were divided into three groups: Group I (n=15) including normal pregnant (NP) women with blood pressure <140∕90 mmHg, without proteinuria, Group II (n=18) including patients with mild PE (MildPE), Group III (n=15) including patients with severe PE (SeverePE). The analysis of serum biomarkers was based on a quantitative sandwich enzyme-linked immunosorbent assay (ELISA), according to the manufacturer's instructions. RESULTS In our study, we found that all biomarkers investigated have higher concentrations in the serum of patients with SeverePE and MildPE than those in the control subjects (Group I, NP), the concentrations were increasing along with the disease activity. The means concentrations of HIF-1A, VEGF, IP-10, MMP-13, better correlated with indices in SeverePE group than in MildPE group. We found that VEGF was the biomarker that best correlates with indices that assess the severity of PE. The best separation of patients with SeverePE from those with MildPE can be done with the help of MMP-13 (82% accuracy), followed by VEGF (80.40% accuracy) and the least good detection being done by dosing IP-10. CONCLUSIONS We can say that, due to high specificity diagnostic accuracy, determination of serum concentrations of MMP-13 and VEGF, could be useful in the diagnosis and distinguishing of patients with SeverePE and may prove useful in the monitoring of the disease course.

The perioperative effect of anesthetic drugs on the immune response in total intravenous anesthesia in patients undergoing minimally invasive gynecological surgery. ROMANIAN JOURNAL OF MORPHOLOGY AND EMBRYOLOGY = REVUE ROUMAINE DE MORPHOLOGIE ET EMBRYOLOGIE 2021; 62:961-969. [PMID: 35673815 PMCID: PMC9289698 DOI: 10.47162/rjme.62.4.08] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Accepted: 05/09/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND The specific mechanism of action of each anesthetic drug on the immune system is still incompletely known. It is important to know how the various anesthetics used in minimally invasive surgery (MIS) act on the inflammatory response because the choice of the anesthetic agent can influence the patient's immune system. AIM Evaluation of the effect of anesthetic drugs used for total intravenous anesthesia (Propofol and Midazolam) on the inflammatory response after minimally invasive gynecological surgery. PATIENTS, MATERIALS AND METHODS The inflammatory response in 20 female patients who underwent minimally invasive gynecological surgery under which intravenous anesthesia was performed. Depending on the combination of anesthetics used, we subdivided the study group into two groups, Group 1 consisting of the patients (n=10) who were given for total intravenous anesthesia, the combination with Midazolam+Fentanyl, and Group 2 (n=10) the patients who received the combination of Propofol+Fentanyl, respectively. Surgical interventional procedures included day surgery: diagnostic and operative hysteroscopy, endometrial ablation, surgical treatment of vulvar disorders. Serological profiling of patients was performed by dosing the serum concentration of nucleotide-binding domain (NOD) and leucine-rich repeat protein 3 (NLRP3) inflammasomes, interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α), IL-10 before and two hours after the surgical procedure. RESULTS In our study, we found that in both groups of patients (Midazolam+Fentanyl - Group 1, Propofol+Fentanyl - Group 2), NLRP3 and cytokines concentrations in the serum were higher after MIS than those before MIS. CONCLUSIONS It appears that both Midazolam and Fentanyl and Propofol and Fentanyl have an immunomodulatory action due to the anti-inflammatory effect of both anesthetics. Therefore, anesthesiologists must choose an anesthetic method that uses individualized anesthetic agents, depending on the patient's immune status and disease.

Abstract
Psoriatic arthritis (PsA) is an inflammatory potentially destructive disease that requires early diagnosis and therapeutic approach. Its main pathogenic event and the condition's hallmark is considered to be enthesitis. Clinical examination of the enthesis can be a challenge in the clinical practice; thus, ultrasonography (US) has emerged as an indispensable imaging tool for evaluating both structural and inflammatory changes of this structure. In the present study, we aimed to analyze the type and frequency of entheseal involvement in PsA patients by US examination, performing a retrospective study on 41 patients diagnosed with PsA. Ultrasonographically confirmed enthesitis, identified according to Outcome Measures in Rheumatology group (OMERACT, initially Outcome Measures in Rheumatoid Arthritis Clinical Trials) definitions, was present in 26 of the included patients, Achilles enthesis being the most common site involved. The prevalence of tendon structure abnormalities and the presence of entesophytes underlines the importance of chronic inflammation on entheseal sites. US examination has proven to be a reliable imaging method, with significant and continuous improvement, which is clearly a requisite part for current understanding and diagnosis of enthesitis and more than this, for the patient follow-up algorithm.

Abstract
Chronic liver disease is a major health issue worldwide and chronic hepatitis C (CHC) is associated with an increased risk of cirrhosis and hepatocellular carcinoma (HCC). There is evidence that the hepatitis C virus (HCV) infection is correlated with immune senescence by way of immune activation and chronic inflammation, which lead to increased metabolic and cardiovascular risk, as well as progressive liver damage. Both the innate and adaptive immunity are firmly tied to the prognosis of an infection with HCV and its response to antiviral therapy. HCV is therefore associated with increased pro-inflammatory status, heightened production of cytokines, prolonged systemic inflammation, as well as increased morbidity and mortality, mainly due to the progression of hepatic fibrosis and HCC, but also secondary to cardiovascular diseases. Viral hepatic pathology is increasingly considered a disease that is no longer merely limited to the liver, but one with multiple metabolic consequences. Numerous in vitro studies, using experimental models of acute or chronic inflammation of the liver, has brought new information on immunopathological mechanisms resulting from viral infections and have highlighted the importance of involving complex structures, inflammasomes complex, in these mechanisms, in addition to the involvement of numerous proinflammatory cytokines. Beyond obtaining a sustained viral response and halting the aforementioned hepatic fibrosis, the current therapeutic “treat-to-target” strategies are presently focused on immune-mediated and metabolic disorders, to improve the quality of life and long-term prognosis of CHC patients.

Abstract
Angiogenesis is a critical component of normal implantation and placentation and underlines the importance of vascularization in early pregnancy. Differentiated expression of angiogenesis factors in different decision tissues during different stages of implantation, indicates their involvement in the regulation of vascular remodeling and angiogenesis. Disorders in vascular development may play a role in the pathogenesis of recurrent abortions. The success of implantation, placentation and subsequent pregnancy evolution requires coordination of vascular development and adaptations at both sides of the maternal–fetal interface. The human implantation process is a continuous process, which begins with the apposition and attachment of the blastocyst to the apical surface of the luminal endometrial epithelium and continues throughout the first trimester of pregnancy until the extravillous trophoblast invades and remodels maternal vascularization. Numerous regulatory molecules play functional roles in many processes, including preparation of the endometrial stroma (decidualization), epithelium for implantation, control of trophoblastic adhesion and invasion. These regulatory molecules include cytokines, chemokines, and proteases, many of which are expressed by different cell types, having slightly different functions as the implant progresses

Abstract
Ankylosing spondylitis (AS) is a progressive common autoimmune inflammatory disease, part of the spondylarthritis group, characterized, besides clinical spinal and peripheral joint inflammation, by enthesitis and new bone formation, that can lead to severe functional impairment. Beyond intensive and continuous research on the pathogenic process extensively performed in recent years, their impact on therapeutic management remains open to future development. Better knowledge of AS pathogenesis have shown results progressively and studies are being performed to advance our current understanding of the disease. It is well known that tumor necrosis factor (TNF) exerts a central role, along with interleukin-17 (IL-17) and interleukin-23 (IL-23), demonstrated by several clinical studies. Similar to other rheumatic inflammatory conditions, SA is associated with an early process of systemic bone loss, both trabecular and cortical, consecutive osteopenia, osteoporosis, and high fracture risk. Current personalized therapeutic options benefit from new published data, to prevent future complications and to improve quality of life.

Abstract
Rheumatoid arthritis (RA) is classified as an inflammatory, chronic autoimmune and disabling disease based on the intricate interplay between environmental and genetic factors. With a prevalence ranging from 0.3 to 1%, RA is the most prevalent inflammatory joint disease observed in adults. Disruption of immune tolerance becomes evident when abnormal stimulation of the innate and adaptive immune system occurs. This cascade of events causes persistent joint inflammation, proliferative synovitis and, ultimately, damage of the underlying cartilage as well as the subchondral bone, leading to permanent joint destruction, deformity and subsequent loss of function. With cytokines being the key to a multitude of biological processes, including inflammation, hematopoiesis and overall immune response, one must inevitably look at the main pathways through which a significant number of those molecules exert their function. Janus kinase/signal transducers and activators of transcription (JAK/STATs) represent one such pathway and, recently, JAK inhibitors (JAKinibs) have shown promise in the treatment of several inflammatory diseases, including RA. This narrative review focuses on the intricate signaling pathways involved as well as on the clinical aspects and safety profiles of JAKinibs approved for the treatment of RA.

Abstract
Burns have become an important public health problem in the last two decades, with just over a quarter of a million deaths annually. Major burns are accompanied by a strong inflammatory response, which will most often lead to systemic response inflammatory syndrome, followed by sepsis and finally induce multiple organ failure. The main mechanism involved in wound healing after burns is the inflammatory process, characterized by the recruitment of myeloid and T cells and by the involvement of numerous cytokines, chemokines, complement fractions, as well as various growth factors. Inflammasomes, protein-based cytosolic complexes, activated during metabolic stress or infection, play a role in modulating and improving the defense capacity of the innate immune system. Nucleotide-binding domain and leucine-rich repeat protein 3 (NLRP3) inflammasome has been studied predominantly and several hypotheses have been issued. Restoring the balance between the pro-inflammatory response and the anti-inflammatory activity is the key element to effective therapy in burns. Severe burns require nutritional support and pharmacotherapy not only for burn area but for different pathological complications of burn injury. In-depth research is required to find new ways to modulate the defense capacity, to prevent the complications of abnormal immune response and to treat burn injuries efficiently.

Abstract
The study assessed whether the increased production of interleukin-1α (IL-1α) and interleukin-1β (IL-1β), as a result of chronic hepatic inflammation, could be the expression of the negative impact on periodontal disease. The study included chronic periodontitis patients who were systemically healthy, chronic periodontitis patients suffering from chronic hepatitis C, as well as control patients, being systemically and periodontally healthy. After periodontal examination and the assessment of certain periodontal parameters, gingival crevicular fluid was collected from all participating patients. By using the enzyme-linked immunosorbent assay method, a quantitative assessment of IL-1α and IL-1β levels was possible. The immunologic results were correlated to the clinical periodontal data. The gingival fluid levels of cytokines were higher for periodontitis patients with chronic hepatitis C than for the systemically healthy periodontitis patients (1.8-fold higher for IL-1α and 2.1-fold higher for IL-1β). In addition, the gingival fluid cytokine levels were significantly higher for the periodontal patients (with/without chronic hepatitis C) than for the control group. Positive correlations were found between gingival fluid IL-1α and IL-1β levels and certain clinical periodontal parameters or the age of the viral hepatitis C diagnosis, in periodontitis patients with chronic hepatitis C. The chronic hepatic inflammation may have an important additional negative impact on the periodontal status, as both inflammatory reactions seem to be promoted by common pro-inflammatory cytokines.

Abstract
Ascorbic acid (vitamin C) is an important water-soluble vitamin found in many fruits and vegetables. It has well-documented beneficial effects on the human body and is used as a supplement, alone or in combination with other vitamins and minerals. Over recent years, research has focused on possible new therapeutic actions in chronic conditions including periodontal disease (PD). We conducted a systematic review on clinical trials from four databases (PubMed, Clinical Trials, Cochrane, Web of Science) which measured plasmatic/salivary levels of ascorbic acid in PD–diabetes mellitus (DM) association. Six studies were included in our review, three of them analyzing patients with different grades of PD and DM who received vitamin C as a treatment (500 mg vitamin C/day for 2 months and 450 mg/day for 2 weeks) or as part of their alimentation (guava fruits), in combination with standard therapies and procedures. Decreased levels of vitamin C were observed in PD patients with DM but data about efficacy of vitamin C administration are inconclusive. Given the important bidirectional relationship between PD and DM, there is a strong need for more research to assess the positive effects of ascorbic acid supplementation in individuals suffering from both diseases and also its proper regimen for these patients.

Abstract
Metatypical basal cell carcinoma (MTBCC) is a rare form of tumor, which associates the clinical and histopathological (HP) characteristics of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), with a 5% chance for the development of metastases. The reference diagnosis remains the HP confirmation from the lesional tissue. The current report illustrates the case of a 74-year-old patient, diagnosed with MTBCC consequently to the biopsy from the clinically malignant lesion with HP and immunohistochemical examination, currently in clinical remission following surgical treatment. The musculoskeletal symptoms represent the patient's admission reason to the Clinic of Rheumatology, where he was diagnosed with paraneoplastic type I complex regional pain syndrome (CRPS-I). The onset was six weeks prior with intense pain in the upper limb, burning sensation and nondermatomal distribution, exacerbated by lowering the position of the upper limb. The clinical evaluation revealed vasomotor disorders: color changes on the skin of the upper limb, venous turgescence on the back of the hands, and local increased temperature. Also, there were evident sudomotor modifications with hyperspiration and fluffy edema. The presence of clinical manifestations associated with the HP confirmation of MTBCC and the information provided by the imaging tests regarding the evaluation of tumor extension advocates for the diagnosis of paraneoplastic CRPS, consequently to both the primary tumor and the pulmonary metastasis. Diagnosis of CRPS-I is generally established on the basis of clinical criteria after excluding other conditions that may explain the degree of pain and the existing dysfunction. The therapist should be aware of the clinical manifestation of CRPS, as early recognition and aggressive treatment often leads to the best response.

Abstract
BACKGROUND Due to its role in angiogenesis, the inducible nitric oxide synthase (iNOS) gene promoter polymorphism may have a presumed role in recurrent spontaneous abortions (RSA). It is an intensely studied protein, a biological mediator, a modulator and an effector molecule by implication in numerous physiological processes: vasodilatation, angiogenesis, immunity, tissue remodeling, smooth muscle activity. AIM Our study aims to investigate a possible association between iNOS -2087A>G (rs2297518) polymorphism and the occurrence of idiopathic recurrent pregnancy loss (RPL). PATIENTS, MATERIALS AND METHODS In this study, as in the previously published one, 169 women, diagnosed with RPL, in the Clinics of Obstetrics and Gynecology, "Filantropia" Municipal Hospital, Craiova, Romania, were subjected to the analysis, from October 2009 to October 2016. As a control group, we used 145 women. Subjects from both groups were genotyped using specific probes for TaqMan polymerase chain reaction (PCR), allelic discrimination technique. RESULTS We evaluated in this study a possible association between iNOS -2087A>G (rs2297518) polymorphism and the occurrence of idiopathic RPL. The chi-square test showed no significant association between the presence of this polymorphism and the increased risk to develop RPL. When we performed a comparative analysis of the frequency of genotypes and our statistical data, it was observed that this polymorphism, iNOS -2087A>G (rs2297518), has not been associated with an increased risk of developing RPL. Also, when one genotype was compared with another, we did not obtain any association that would have statistical significance, between the presence of this polymorphism and the increased risk for patients to develop RPL [in dominant - A allele carriers, iNOS 2087 AG+AA vs. GG: odds ratio (OR) 1.31, 95% confidence interval (CI) 0.83-2.07, p=0.24]. Analyzing the overall risk of developing RPL by iNOS 2087 single-nucleotide polymorphism (SNP) genotype frequencies, between controls and RPL patients (which were stratified by number of consecutive PLs), taking into account the number of consecutive pregnancies, the chi-square test showed no association between the presence of this polymorphism and the increased risk for developing RPL in all three subgroups we analyzed (in a dominant model - A allele carriers, iNOS 2087 AG+AA vs. GG: the first subgroup, OR 1.31, 95% CI 0.83-2.07, p=0.24; the second subgroup, OR 1.26, 95% CI 0.76-2.11, p=0.37; the three subgroup, OR 1.4, 95% CI 0.77-2.53, p=0.272). CONCLUSIONS The iNOS -2087A>G (rs2297518) gene polymorphism does not influence RPL in the study area of Dolj County, Romania.

Abstract
Neuroinflammation is a complex process that contributes to the pathogenesis of both immune mediated and neurodegenerative pathologies. Systemic lupus erythematosus (SLE) is the prototype of connective tissue diseases that can present the complete spectrum of neurological and psychiatric dysfunctions. The precise etiological diagnosis of neuropsychiatric systemic lupus erythematosus (NPSLE) is rather difficult to be established and it is still controversial the exact timing of neuropsychiatric (NPS) events: either central nervous system (CNS) is the initial target of autoimmune abnormalities, either NPS symptoms are a part of multisystem involvement. Ischemic and inflammatory mechanisms have an important input on NPSLE pathogenesis. Neuroinflammation, consequent to blood-brain barrier (BBB) damage, local and systemic production of autoantibodies, determine neuronal injury and apoptosis, further responsible for diffuse cerebral events, mostly cognitive dysfunction and psychotic disorder. Moreover, SLE complications or therapy complications can interfere and contribute to complex clinical manifestations that can be present in SLE patients. Understanding the role of each pathogenic way can provide not only an early diagnosis, but a more accurate therapeutic approach of these patients.

Abstract
BACKGROUND Placental angiogenesis and vascular adaptation during pregnancy, along with diminished placental trophoblastic vascular endothelial growth factor immunoreactivity, play an important role in the early stages of human pregnancy, being possible causes of recurrent pregnancy loss (RPL). AIMS Our focus was directed towards investigating a possible association between vascular endothelial growth factor receptor-2 (kinase insert domain receptor) VEGFR-2 (KDR) -604A>G (rs 2071559) gene polymorphism and RPL in the study area of Dolj County, Romania. PATIENTS, MATERIALS AND METHODS In this study, 169 women, diagnosed with RPL, were included. They were hospitalized in the Clinics of Obstetrics and Gynecology, "Filantropia" Municipal Hospital, Craiova, during the following period: October 2009-October 2016. The control group consisted of 145 women. All subjects were genotyped by means of allelic discrimination TaqMan polymerase chain reaction assay with specific probes. RESULTS No statistically significant difference was observed between the RPL patients and the control group, when one genotype was compared to another [in a dominant model, -604 AG+GG vs. AA: odds ratio (OR) 1.71, 95% confidence interval (CI) 0.99-2.96, p=0.051]. While studying the overall risk of RPL by the genotype frequencies of KDR polymorphism between controls and RPL patients, which were stratified according to the number of consecutive pregnancy losses (PLs), the chi-square test showed a significant association between the presence of this polymorphism and the increased risk observed in patients with four or more consecutive PLs, to develop RPL (in a dominant model - G allele carriers, KDR -604 AG+GG vs. AA: OR 1.91, 95% CI 1.03-3.52, p=0.037). These results prove that G allele carriers have an increased risk of RPL about 1.91-fold higher than those with the AA genotype do. Although our results bear limited statistical significance, the study nonetheless represents a step forward in the evaluation of recurrent abortion, which has not yet been explored sufficiently. CONCLUSIONS VEGFR-2 (KDR) polymorphism does not influence RPL susceptibility in the study area of Dolj County, Romania. Therefore, further studies, which include a larger sample size, are required in order to clarify the role of KDR polymorphism in RPL.

Abstract
Sepsis is currently defined as the presence of organ dysfunction occurring as the result of a disturbed host response to a serious infection. Sepsis is one of the most common diseases, which cause mortality and a considerable absorber of healthcare resources. Despite progress in technology and improving knowledge of pathophysiology, the disease mechanism is still poorly understood. At present, diagnosis is based on non-specific physiological criteria and on the late identification of the pathogen. For these reasons, the diagnosis may be uncertain, treatment delayed or an immunomodulatory therapy cannot be established. An early and reliable diagnosis is essential to achieve better outcomes on disease progression. The host response to infection involves hundreds of many mediators of which have been proposed as biomarkers. There is a need for new diagnostic approaches for sepsis, new sepsis biomarkers that can aid in diagnosis, therapeutic decision and monitoring of the response to therapy. The differentiation of sepsis from non-infectious systemic inflammatory response syndrome is difficult, and the search for a highly accurate biomarker of sepsis has become one important objective of the medicine. The goal of our review is to summarize the recent advances on the most commonly studied serum biomarkers, evaluated in clinical and experimental studies, for early diagnosis of sepsis and their informative value in diagnosis, prognosis, or response to therapy. In this context, we have tracked the clinical utility of measuring serum biomarkers, such as procalcitonin, pro- and anti-inflammatory cytokines, C-reactive protein, leptin and their combinations. Currently, has not been identified an ideal biomarker to aid in the diagnosis of sepsis. It is hoped that the discovery of new serum markers, as well as their combinations, will serve for the diagnosis and prognosis of sepsis.

Abstract
In the present study, we aimed to estimate the concentrations of cytokines (interleukin 6, IL-6, tumor necrosis factor-α, TNF-α) and auto-antibodies (rheumatoid factor IgM isotype, IgM-RF, antinuclear auto-antibodies, ANA, anti–cyclic citrullinated peptide antibodies IgG isotype, IgG anti-CCP3.1, anti-cardiolipin IgG isotype, IgG anti-aCL) in serum of patients with eRA (early rheumatoid arthritis) and HCVrA (hepatitis C virus-related arthropathy) and to assess the utility of IL-6, TNF-α together with IgG anti-CCP and IgM-RF in distinguishing between patients with true eRA and HCVrA, in the idea of using them as differential immunomarkers. Serum samples were collected from 54 patients (30 diagnosed with eRA-subgroup 1 and 24 with HCVrA-subgroup 2) and from 28 healthy control persons. For the evaluation of serum concentrations of studied cytokines and auto-antibodies, we used immunoenzimatique techniques. The serum concentrations of both proinflammatory cytokines were statistically significantly higher in patients of subgroup 1 and subgroup 2, compared to the control group (p < 0.0001). Our study showed statistically significant differences of the mean concentrations only for ANA and IgG anti-CCP between subgroup 1 and subgroup 2. We also observed that IL-6 and TNF-α better correlated with auto-antibodies in subgroup 1 than in subgroup 2. In both subgroups of patients, ROC curves indicated that IL-6 and TNF-α have a higher diagnostic utility as markers of disease. In conclusion, we can say that, due to high sensitivity for diagnostic accuracy, determination of serum concentrations of IL-6 and TNF-α, possibly in combination with auto-antibodies, could be useful in the diagnosis and distinguishing between patients with true eRA and HCV patients with articular manifestation and may prove useful in the monitoring of the disease course.

Abstract
AIM Accurate diagnosis and early treatment in rheumatoid arthritis (RA) can lead to a good outcome and a correct management of the disease. We aimed toinvestigate the prognostic value of anti-RA33 antibodies, by evaluating the relationship with ultrasonographic (US) findings in patients with early RA. MATERIAL AND METHODS We performed a prospective study which included 29 patients, diagnosed with early RA according to the ACR/EULAR 2010 criteria and 21 sex and age-matched control subjects. All patients underwent clinical and biological assessment, followed by US examination in grayscale (GS) and power Doppler (PD) at baseline and after 12 months [from the second to the fifth metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints and wrists (RCC), in dorsal aspect]. The second and fifth MCP joints were scanned also in lateral aspects. RESULTS The initial GS evaluation revealed the presence of synovitis in all 29 patients; PD found at least one joint with a PD grade higher than 1 in 23 patients, higher than 2 in 20 patients, and grade 3 in 6 patients; at 12 months, we revealed the presence of GSUS synovitis in 25 patients and PDUS examination found active synovitis in 12 subjects. In those patients, the anti-RA33 titre was significantly lower compared to those without PDUS active synovitis (p=0.031), with a moderately negative correlation (r=-0.519, p=0.0039). CONCLUSIONS The current study shows that anti-RA33 antibodies might constitute an additional tool for diagnosing early RA patients and can help identify patients with mild disease and a low level of activesynovitis.

Determination of VEGFR-2 (KDR) 604A>G Polymorphism in Pancreatic Disorders. Int J Mol Sci 2017; 18:ijms18020439. [PMID: 28218664 PMCID: PMC5343973 DOI: 10.3390/ijms18020439] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2016] [Accepted: 02/03/2017] [Indexed: 12/15/2022] Open
Abstract
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 correlation between insulin-like growth factor with glycemic control, glomerular filtration rate, blood pressure, hematological changes or body mass index in patients with type 2 diabetes mellitus. ROMANIAN JOURNAL OF MORPHOLOGY AND EMBRYOLOGY = REVUE ROUMAINE DE MORPHOLOGIE ET EMBRYOLOGIE 2017; 58:857-861.

Abstract
Insulin-like growth factor (IGF) family is made up of two polypeptides, IGF-I and IGF-II, six specific binding proteins (IGFBPs 1-6) and specific receptors. IGF-I is involved in the regulation of growth and cellular proliferation and has a similar structure to insulin. The major IGF transport function is attributed to IGFBP-3. Some studies have highlighted the association between IGF and diabetes. The aims of this study were to analyze the correlation between IGF with glycemic control, glomerular filtration rate (GFR), blood pressure, hematological changes or body mass index (BMI) in patients with type 2 diabetes mellitus (T2DM). Thirty patients with T2DM and thirty non-diabetic control patients were included in this study. Clinical, anthropometric, biochemical parameters and morphology of blood smear were recorded. Blood pressure was determined by mercury sphygmomanometer. The anthropometric measurement included BMI. The biochemical parameters included fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), GFR, serum IGF-I, IGFBP-3 levels. The IGF-I÷IGFBP-3 ratio was evaluated. The plasma glucose was determined enzymatically, HbA1c was determined by high-performance liquid chromatography (HPLC) and GFR was calculated automatically. IGF-I was measured by immunoradiometric assay (ELISA - enzyme-linked immunosorbent assay) and IGFBP-3 by sensitivity immunoassay. For the analysis of the morphology of blood smear, May-Grünwald-Giemsa (MGG) was used as staining technique. The microscopic examination was performed initially with the objectives of 10×÷20× and subsequently with an immersion objective of 100×. Image acquisition was done after the examination of the preparations obtained with a 40× objective, using Image Pro Plus 6.0 software. In the present study, we observed that T2DM leads to an increase in the IGF-I and IGFBP-3 levels. No relationship was obtain between IGF-I, IGFBP-3 levels and IGF-I÷IGFBP-3 ratio with neither parameters studied. The difference of serum IGF-I and IGFBP-3 levels between patients with T2DM and subjects without diabetes showed that IGF-I may be a useful marker for diabetes mellitus and IGFBP-3 for possible complications of this affection.

The role of autoantibodies in health and disease. ROMANIAN JOURNAL OF MORPHOLOGY AND EMBRYOLOGY = REVUE ROUMAINE DE MORPHOLOGIE ET EMBRYOLOGIE 2016; 57:633-638.

Abstract
Serum of healthy individuals contains antibodies that react with self and non-self antigens, generated in absence of external antigen stimulation. These antibodies, called natural antibodies, are particularly IgM isotype, are considered natural autoantibodies (NAA), displaying a moderate affinity for self-antigens. Although incidence of NAA in healthy individuals is not reported, it is established that autoreactive antibodies and B-cells, as well as autoreactive T-cells, are present in healthy persons. The functional abilities of NAA are not clear but is well accepted that they may participate in a variety of activities, such as maintenance of immune homeostasis, regulation of the immune response, resistance to infections, transport and functional modulation of biologically active molecules. On the other hand, specific adaptive immune responses through high-affinity, class-switched IgG autoantibodies, which bind self-proteins, can cause tissue damage or malfunctions, inducing autoimmune diseases. The new technology that allows for more autoantibody screening may further enhance the clinical utility of autoantibody tests, making it possible to diagnose autoimmune disease in its early stages and to intervene before installing injuries. The aim of this review paper is to succinctly analyze the progress in the physiological role and regulatory significance of natural autoantibodies in health and disease.
