Effect of remote ischemic postconditioning on left ventricular ejection fraction in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

BACKGROUND: Ischemic conditioning may help patients with ST-segment elevation myocardial infarction (STEMI) to limit ventricular remodeling. OBJECTIVES: To investigate the effect of remote ischemic postconditioning (RIPC) on left ventricular function during primary percutaneous coronary intervention (PPCI) in patients with STEMI. MATERIAL AND METHODS: Pre- and post-test intervention study with a total of 60 STEMI patients. Patients were divided in two groups: with and without RIPC. RESULTS: During the 6-month follow-up, a significant difference in left ventricular ejection fraction was observed in patients who underwent PPCI, which was higher in the group with RIPC in comparison with the group without RIPC: 1.0% (-1.0 to 4.3) vs. -1.0% (-4.0 to 1.3), p = 0.033. In addition, at 6-month measurement, left ventricular end-systolic volume in patients without RIPC was higher in comparison with their counterparts: 79.3 ± 30.5 mL vs. 64.4 ± 21.4 mL, p = 0.032. CONCLUSIONS: RIPC shows favorable effects on left ventricular function and, therefore, in the future, it could be a potential cardioprotective strategy against ischemia-reperfusion injury in STEMI patients.

The Difference of sVE-Cadherin Levels between Dengue Hemorrhagic Fever Patients with Shock and without Shock.

BACKGROUND: Dengue virus infection is an infectious disease caused by the dengue virus and transmitted by the Aedes aegypti mosquito. Dengue virus (DEN-V) consists of 4 serotypes, namely DEN-1, DEN-2, DEN-3, and DEN-4. The most feared result of DHF is death. Death in children is caused by hypovolemic shock due to plasma leakage from intravascular to extravascular space due to endothelial dysfunction. AIM: This study aims to analyse difference in sVE-Cadherin levels in Dengue Hemorrhagic Fever (DHF) with and without shock. MATERIAL AND METHODS: The method of taking samples is consecutive sampling, namely the research subjects obtained based on the order of entry in the hospital with a comparative cross-sectional design. From the results of the calculation using the sample formula, the sample size for each group is set at 32 people. So that the total sample size used for both groups is 64 people. The serum sVE-Cadherin levels using the ELISA method. The statistical test used is the independent t-test. The value of p < 0.05 was said to be statistically significant. RESULTS: The result showed that there was no difference in mean sVE-Cadherin levels between DHF patients with shock and without shock (p > 0.05). CONCLUSION: This study concluded that there was no difference in mean of sVE-Cadherin level in DHF patients with shock and without shock.

The Expression of Transforming Growth Factor Beta-1 and Interleukin-6 on Human Prostate: Prostate Hyperplasia and Prostate Cancer.

BACKGROUND: Prostate hyperplasia and prostate cancer are two of the most common pathological condition of the prostate to be found on male. Both of these diseases share common pathogenesis involving inflammation of prostatic tissues. Chronic inflammation will induce the release of cytokines, followed by cells injury and tissues damage. One of the cytokines that play a role in prostate pathology is IL-6. The inflammation will also induce the releases of anti-inflammatory cytokines such as TGFß-1. AIM: This study aims to analyse the expression of IL-6 and TGFß-1, in prostate hyperplasia and prostate cancer. MATERIAL AND METHODS: This is an observational study, using paraffin-embedded tissue samples of prostate hyperplasia and prostate cancer. Samples were obtained from the laboratory of Pathological Anatomy, Faculty of Medicine, Andalas University, Padang, Indonesia. Immunohistochemistry was performed to detect the cytokine expression, and a semiqunatitaves measurement according to Immunoreactive score (IRS) was performed for evaluation. For the TGFß-1, the stromal expression was also analysed by measurement of the stromal stained area. The correlation of cytokine expression to Gleason index score was also analysed in prostate cancer. RESULTS: The result showed that this study found that TGFß-1 was detected both in the stromal component as well as epithelial. With the stromal being the dominant site of expression. The stromal TGFß-1 expression was of significantly higher in prostate hyperplasia compares to prostate cancer (p < 0.05), while the epithelial expression of TGFß-1 was not found to be significantly different. IL-6 was mostly expressed intracytoplasmic in epithelia. The IL-6 expression was significantly higher in prostate cancer compared to hyperplasia. However, there was no significant correlation to found between IL-6 expression to the Gleason Score among prostate cancers. CONCLUSION: This study concluded that there were differences in expression of both TGFß-1 and IL-6 between prostate hyperplasia and prostate cancer tissue by immunohistochemistry.

BACKGROUND: Dengue infection is one of the problems in the national health sector in Indonesia because the incidence and mortality in Indonesia due to dengue infection is still very high. In 2005 Indonesia became the highest contributor to dengue infection in Southeast Asia (53%) with 95.270 people and 1.298 deaths. AIM: This study aims to analyse differences in angiopoietin-2 levels in dengue hemorrhagic fever (DHF) with and without shock. METHODS: This study was a consecutive sampling design with the research subject was obtained based on the order of admission to the hospital - the serum Angiopoietin-2 levels using the ELISA method. The statistical test used is the independent t-test. The value of p < 0.05 was said to be statistically significant. RESULT: The result showed that the mean of Angiopoietin-2 levels in DHF patients with shock was higher than in DHF (p < 0.05). CONCLUSION: This study concluded that there was a difference in the average level of Angiopoietin-2 among DHF patients with shock compared to without shock.

Differences in Expression of Inflammatory Mediator in Mucosal and Polyp Tissue between Chronic Rhinosinusitis and Recurrent Chronic Rhinosinusitis.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) remains a challenging clinical entity with its propensity for recurrence. This disease decreases the patients' quality of life and creates a high economic burden. An effort to investigate the aetiology of recurrent polyps has to be more alert. AIM: This study aims to prove the differences in expression of IL-5, IL-8, IL-17A and TGF-ß1 in mucosal and polyp tissue between CRSwNP and recurrent CRSwNP and also to determine which expression of cytokines that have the main role in mucosal and polyp tissue in recurrent CRSwNP. MATERIAL AND METHODS: An observational study was conducted with a comparative cross-sectional design of CRS patients with 15 recurrent CRSwNP and CRSwNP who had never undergone surgery for as many as 15 polyps. Mucosal specimens of nasal polyps are taken by brushing, and polyp tissue specimens are taken during surgical removal of nasal polyps. Specimens from the polyp mucosa were examined by ELISA while the polyp tissue specimens were carried out immunohistochemistry (IHC). RESULTS: The result showed that there is a significant difference in IL-5 expression in the polyp mucosal between CRSwNP with recurrent CRSwNP, where expression is higher in recurrent CRSwNP. The expression of IL-8, IL-17 and TGF-ß1 were lower in recurrent CRSwNP, but the difference was not significant. In nasal polyp tissue, there is a significant difference in TGF-ß1 and IL-8 expression between CRSwNP and recurrent CRSwNP, where the expression of both cytokines is lower in recurrent CRSwNP. Interleukin-5 expression was higher in recurrent CRSwNP than CRSwNP, but the difference was not significant. In the polyps mucosal, IL-5 has the main role in recurrent CRSwNP polyp, whereas TGF-ß has the main role in polyp tissue. CONCLUSION: This study concluded that the expression of IL-5 in the mucosa could be examined with simple techniques like brushing before polypectomy or FESS was performed to determine the possibility of polyps recurrencies.

Association of Inflammation Mediator in Mucosal and Tissue of Chronic Rhinosinusitis with Recurrent Nasal Polyp.

BACKGROUND: Chronic rhinosinusitis with polyps (CRSwNP) have a high risk of recurrence and patients often experience repeated surgery. There are several types of inflammatory patterns in CRSwNP, such as Th2 inflammation (eosinophilic) and Th1/Th17 inflammation (neutrophilic). AIM: This study aims to determine the expression of IL-5, IL-8, IL-17A and TGF-ß in recurrent CRSwNP using the most convenient and non-invasive examination tool such as brushing the mucosal polyp and find out its correlation with polyp tissues. MATERIAL AND METHODS: A cross-sectional comparative study was carried out on 15 samples of mucosal brushing and polyp tissue. Expressions of IL-5, IL-8, IL-17A and TGF-ß on mucosa were measured using the Enzyme-Linked Immunosorbent Assay (ELISA) examination and tissues using Immunohistochemical (IHC) examination. RESULT: The result showed that Only IL-5 has a significant relationship between mucosa and tissue with moderate positive correlation (p < 0.05; r = 0.527). CONCLUSION: This study concluded that mucosa brushing could be used as a simple and non-invasive examination to observe the expression of IL-5 in recurrent CRSwNP. IL-5 is one of the cytokines that mark the Th2 (eosinophilic) inflammatory pattern where eosinophilic polyps are closely related to recurrence.

The Effect of Mesenchymal Stem Cell Wharton's Jelly on ADAMTS-4 and iNOS Levels in Osteoarthritis Rat Model.

BACKGROUND: Osteoarthritis (OA) is one of the most common diseases among the elderly. OA occurs due to an imbalance between degradation and synthesis in articular joint tissue, causing changes in joint components such as cells, matrices and molecular production. Therefore, knowledge of cartilage-degrading enzymes such as ADAMTS-4 and iNOS is needed. AIM: This study aims to prove the effect of Mesenchymal Stem Cell Wharton Jelly on decreasing ADAMTS-4 levels as cartilage-degrading enzymes and increasing levels of iNOS which showed the immunosuppressive potential of MSC-WJ in cases of osteoarthritis in vivo. MATERIAL AND METHODS: This research is an experimental study with the design of Post-test-Only Control Group Design. The sample consisted of 16 OA rats as a control group and 16 OA rats treated with MSC-WJ as a treatment group. OA induction is done by injection of monosodium iodoacetate (MIA) into the intra-articular right knee. Giving MSC-WJ is done in the third week after MIA induction. The serum ADAMTS-4 and iNOS levels were measured after 3 weeks treated with MSC-WJ using the ELISA method. The statistical test used is an independent t-test. The value of p < 0.05 was said to be statistically significant. RESULT: The result showed that serum ADAMTS-4 levels were lower in the group treated with MSC-WJ than in the control group, but not statistically significant (p > 0.05). Serum iNOS levels were higher in the group treated with MSC-WJ than in the control group (p < 0.05). CONCLUSION: This study concluded that MSC-WJ significantly reduced ADAMTS-4 levels and increased the serum iNOS levels of OA rats.

The Effect of Mesenchymal Stem Cell Wharton's Jelly on Matrix Metalloproteinase-1 and Interleukin-4 Levels in Osteoarthritis Rat Model.

BACKGROUND: Osteoarthritis (OA) is generally considered a degenerative joint disease caused by biomechanical changes and the ageing process. In OA pathogenesis, the development of OA is thought to be regulated largely by excess matrix metalloproteinase (MMP), which contributes to the degradation of extracellular matrices such as MMP-1 and Interleukin-4. AIM: This study aims to prove the influence of Mesenchymal Stem Cell Wharton Jelly on decreasing MMP-1 levels and increasing IL-4 which is a specific target as a target component in cases of osteoarthritis in vivo. MATERIAL AND METHODS: This research is an experimental study with the design of Post-Test-Only Control Group Design. The sample consisted of 16 OA rats as a control group and 16 OA rats treated with MSC-WJ as a treatment group. OA induction is done by injection of monosodium iodoacetate (MIA) into the intra-articular right knee. Giving MSC-WJ is done in the third week after MIA induction. The serum MMP-1 and IL-4 levels were measured after 3 weeks treated with MSC-WJ using the ELISA method. The statistical test used is an independent t-test. The value of p < 0.05 was said to be statistically significant. RESULTS: The result showed that serum MMP-1 levels were higher in the group treated with MSC-WJ than in the control group (p < 0.05). Serum IL-4 levels were higher in the group treated with MSC-WJ than in the control group (p < 0.05). CONCLUSION: This study concluded that MSC-WJ increased MMP-1 levels and IL-4 levels in serum OA rats. MSC-WJ showed a negative effect on MMP-1 in the serum of OA rats.

The analysis of matrix metalloproteinase-8 in gingival crevicular fluid and periodontal diseases.

BACKGROUND: Periodontal disease, also generally called periodontitis or gum disease, is a chronic infection-induced inflammatory disease that causes tooth loss if not properly treated, and is considered as a modifying factor in systemic health. Gingival crevicular fluid (GCF) matrix metalloproteinase-8 (MMP-8) is an inflammatory marker found in periodontal pathologic conditions. Gingivitis, a nondestructive type of periodontal disease, can progress to periodontitis if left untreated. Therefore, assessing the level of MMP-8 with comfortable methods and no tissue intervention can determine the progression of the periodontal disease for a better treatment. OBJECTIVE: The purpose of the present study is to determine the relationship between MMP-8 in GCF and periodontal disease. SETTING AND DESIGN: This is a cross-sectional study that took place in West Sumatra, Indonesia from June to December 2013. MATERIALS AND METHODS: This study involves 60 respondents who are divided into three groups based on the periodontal disease index. The samples consist of 20 healthy individuals, 20 with mild gingivitis, and 20 periodontitis initial. GCF was collected from each group. MMP8 level in GCF was tested by using ELISA technique. STATISTICAL ANALYSIS: Data were analyzed with SPSS version 17 Software. ANOVA test was used to determine the differences in average levels of MMP-8. Bonferroni post hoc test was used to discover which spesific means differed. RESULTS: The level of MMP-8 is significantly different between the healthy group and mild gingivitis group, between the healthy group with mild periodontitis group, and also between groups with mild gingivitis and mild periodontitis (P < 0.05). CONCLUSION: The findings of this study can be used by practitioners of dentistry to establish a proper diagnosis and appropriate treatment of periodontal disease by measuring the scale of MMP-8, to prevent or to minimize further complication in periodontitis patients.

Analyzing Determinant Factors for Pathophysiology of Functional Dyspepsia Based on Plasma Cortisol Levels, IL-6 and IL-8 Expressions and H. pylori Activity.

BACKGROUND: there are many determinant factors that may play roles in pathophysiology of functional dyspepsia. One of them is psychological stress that can increase plasma cortisol levels, alter inflammation process and affect Helicobacter pylori activity. No study has been conducted to find out the dominant factor among them. This study aimed to find the dominant factor among plasma cortisol levels, IL-6 and IL-8 expressions and H.Pylori activity, as the determinant factors in the pathophysiology of functional dyspepsia. METHODS: a cross-sectional study was conducted in 80 patients with dyspepsia syndrome at M. Djamil General Hospital, Padang, West Sumatera, Indonesia. The patients were categorized into two groups, i.e. the stress and non-stress group, which were identified using DASS 42 questionairre criteria. The inflammatory expressions (IL-6 and IL-8 expressions) as well as H. pylori activity were determined using immunohistochemistry of gastric biopsy specimens; while plasma cortisol levels was measured from peripheral blood samples. Data were analyzed using binary multivariate logistic regression. RESULTS: there were 80 patients with functional dyspepsia with mean age of 38.9 years old. The morning cortisol levels was found significantly higher in the stress group. Higher IL-6 and IL-8 expressions were found in patients of non-stress group compared to those in the other group (IL-6: 73.28 (SD 16.60) vs. 72.95 (SD 19.49; and IL-8: 18.45 (SD 17.32) vs. 14.80 (SD 12.71)); although stastically not significant. There was greater Helicobacter pylori activity in the group with psychological stress compared to those in the non-stress group since there was antigen-antibody reaction invading the submucosa. The dominant determinant factor was the afternoon plasma cortisol levels. CONCLUSION: many factors can become the determinant factors for gastric mucosal damage; however, our study has demonstrated that the dominant factor is afternoon plasma cortisol levels.

The Effect of Psychological Stress on Mucosal IL-6 and Helicobacter pylori Activity in Functional Dyspepsia.

BACKGROUND: pathophysiology of functional dyspepsia remains poorly understood. Many factors such as gastric motility disorder, visceral hypersensitivity, Helicobacter pylori (Hp) infection, psychological stress and excessive gastric acid secretion play roles in this symptom. Psychological stress may promote peptic ulcer and has an effect on ulcers-associated Hp. This study aimed to determine Helicobacter pylori activity and expression of mucosal IL-6 and their association with psychological stress. METHODS: a cross-sectional study was done among 40 outpatients with dyspeptic syndromes in M. Djamil General Hospital and two-community health centers in Padang. The subjects were divided into two groups, with and without psychological stress, which were identified using DASS 42. Gastric biopsy specimens and peripheral blood samples were taken while performing esophagogastroduodenoscopy. Immunohistochemistry methods was used to determine the expression of IL-6 and Hp in gastric mucosa. The correlation of each variable in the group experiencing psychological stress and non-stress was analyzed using Chi-square test. RESULTS: there were 40 patients with functional dyspepsia with average age of 37.58(SD 11.82) years old. The cortisol levels were significantly different between both groups (non-stress vs. stress groups); moreover, morning cortisol level in psychological stress group was higher beyond normal limit. Inter-Leukin-6 expression, as the evidence of inflammatory activity, seemed higher in non-stress group than the group with psychological stress (8.25% vs. 7.25%). Helicobacter pylori activity was seemed to be increased in the stress group as characterized by higher numbers of invasion to the sub mucosa epithelium compared to the non-stress group (11 vs. 7 subjects). CONCLUSION: psychological stress seems to have no correlation with IL-6 in gastric mucous of patients with functional dyspepsia; however, there is an evidence of increasing activity of Helicobacter pylori.

Vitamin D status in under-five children with a history of close tuberculosis contact in Padang, West Sumatra.

BACKGROUND AND OBJECTIVE: Serum vitamin D influences cellular immunity against Mycobacterium tuberculosis, particularly in under-five children. Vitamin D insufficiency and deficiency as well as tuberculosis (TB) are highly prevalent in Indonesia. This study described the association of serum vitamin D in the incidence of latent TB in under-five children with a history of close TB contact. METHODS AND STUDY DESIGN: This cross-sectional study examined 178 under-five children with a history of close TB contact, with 98 index cases from primary health care facilities in Padang. Latent TB was defined based on a positive tuberculin skin test. Serum vitamin D was determined using ELISA method. General characteristics for age, sex, socioeconomic status, contact score, BCG scars, and nutritional status were also collected. RESULTS: Of 168 eligible subjects, 40.5% had latent TB, however no differences between 'latent TB' and 'without latent TB' were observed in participant characteristics. Vitamin D deficiency, insufficiency, and sufficiency were observed in 23.3%, 43.5%, and 33.3% of children, respectively. In general, the 'latent TB' group had lower serum vitamin D than those in the 'without latent TB' group, stratified by age, contact score and nutritional status; however, significant differences were observed in children age <1 years (18.0±2.6 vs 31.2±10.5, respectively, p=0.013). Nevertheless, no associations between the two groups were observed using multivariate analysis. CONCLUSION: Vitamin D status was not associated with the incidence of latent TB among under-five children with a history of close TB contact, although this may not obtain in children aged <1 year old.

Effect of Allogeneic Bone Marrow-mesenchymal Stem Cells (BM-MSCs) to Accelerate Burn Healing of Rat on the Expression of Collagen Type I and Integrin α2ß1.

BACKGROUND AND OBJECTIVE: Burn is a public health problem, it causes physical disability even death. Treatment of burn wound has been conducted in various ways, but the satisfactory healing has not been provided. Bone marrow-derived mesenchymal stem cells (BM-MSCs) treatment is one of attempt to burn recovery, accelerate wound healing and angiogenesis. This study aimed to investigate the effect of allogeneic BM-MSC treatment on the expression of collagen type I and integrin α2ß1 in burn skin tissue of rat observed on day 14. MATERIALS AND METHODS: Twelve Wistar rats divided into two groups, control group (injected with phospate buffer solution) and treatment group (injected with BM-MSC). Rat was anaesthetized with xylazine and ketamine (ratio 1:1), fur of rat's back was shaved and full thickness burn was made by boiling plate in hot water for 30 min and patched on the back for 20 min. The burns were covered by tegaderm film and elastomult haft. Antalgin as an analgetic was injected to rats during observation process. Burns of rat was observed on day 14. In this study one-way analysis of variance test and Tukey as a further test were analyzed. RESULTS: The results showed that the healing time of allogeneic BM-MSC treatment on burn skin tissue rats was faster, the thickness of collagen type I in burn skin tissue of rats was thicker (0.977 µm) than controls (0.475 µm) and statistically demonstrated significant differences (p = 0.000). The average percentage of integrin α2ß1 expression was higher (2.94%) than control group (2.34%), but the differences were not statistically significant (p = 0.176). CONCLUSION: The study concluded that BM-MSC treatment was able to accelerate the healing process of burns by increasing the thickness of the collagen and the percentage of integrin α2ß1, thus accelerated the cell migration involved during wound healing.
