The relation between international normalized ratio and mortality in acute pulmonary embolism: A retrospective study.

BACKGROUND: Acute pulmonary embolism (PE) is a serious clinical disease characterized by a high mortality rate. The aim of this study was to assess the prognostic value of international normalized ratio (INR) in acute PE patients not on anticoagulant therapy. METHODS: The study included 244 hospitalized acute PE patients who were not receiving previous anticoagulant therapy. Based on their 30-day mortality, patients were categorized as survivors or non-survivors. INR was measured during the patients' admission, on the same day as the diagnosis of PE but before anticoagulation started. RESULTS: Thirty-day mortality occurred in 39 patients (16%). INR was higher in non-survivors than in survivors (1.3±0.4 vs 1.1±0.3, P=.003). In multivariate analysis, INR (HR: 3.303, 95% CI: 1.210-9.016, P=.020) was independently associated with 30-day mortality from PE. Inclusion of INR in a model with simplified pulmonary embolism severity index (sPESI) score improved the area under the receiver operating characteristics (ROC) curve from 0.736 (95% CI: 0.659-0.814) to 0.775 (95% CI: 0.701-0.849) (P=.028). Also, the addition of INR to sPESI score enhanced the net reclassification improvement (NRI=8.8%, P<.001) and integrated discrimination improvement (IDI=0.043, P=.027). CONCLUSION: Elevated INR may have prognostic value for 30-day mortality in acute PE patients not on anticoagulation. Combining INR with sPESI score improved the predictive value for all-cause mortality. However, further large-scale studies are needed to confirm it's prognostic role.

Protective Effects of Quercetin on Necrotizing Enterocolitis in a Neonatal Rat Model.

INTRODUCTION: Necrotizing enterocolitis (NEC) is one of the major health problems of newborn period. To date, a large amount of chemicals have been tested for NEC and some showed limited beneficial effects. The research for better results still continues. This study aims to investigate the effects of quercetin (QE) on NEC treatment in rats. METHODS: Newborn rats were divided into control, NEC, and NEC + QE groups. In NEC and NEC + QE groups, experimental NEC was induced. NEC + QE group animals were also given QE. Weight changes of the animals were recorded, and serum total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA), and glutathione (GSH) levels were measured. Histologic evaluation of the distal ileum and the terminal deoxynucleotidyl transferase dUTP nick end labeling staining were performed. RESULTS: A significant increase in the TAS levels was observed in NEC + QE group. Only NEC group exhibited significantly higher TOS and MDA levels and lower GSH levels. Rats in the NEC + QE group had better histopathology and less apoptosis than NEC group. CONCLUSION: QE is effective in enhancing antioxidant defense mechanism, limiting oxidative stress, reducing intestinal damage, and preventing NEC development.

Relation of Low T3 to One-Year Mortality in Non-ST-Elevation Acute Coronary Syndrome Patients.

BACKGROUND: Low T3 which is defined as decreased triiodothyronine (T3) and normal thyroid-stimulating hormone (TSH) and thyroxin (T4) levels is present in many acute diseases and is related to increased mortality. We studied low T3 level's relation to long-term mortality in non-ST-elevation acute coronary syndrome (NSTE-ACS) patients. METHODS: T3, T4, and TSH levels of consecutive NSTE-ACS patients were measured. Patients with normal T4 and TSH levels, but low T3 level were defined as low T3 group. Patients with normal T3, T4, and TSH levels were defined as normal group. Clinical and laboratory findings in these two groups were compared. In addition, we examined low T3 level's relation to early and long-term mortality. RESULTS: Mean patient age was 61 ± 13 (67% male) and 31 (11%) patients had low T3 level. Free T3 values were negatively correlated with age, serum creatinine, and brain type natriuretic peptide values at the time of admission (r = -0.452, P < 0.0001; r = -0.255, P < 0.0001; r = -0.544, P < 0.0001, respectively). Mortality at 1 month and 1 year was higher in low T3 group (3% vs. 16%, P = 0.002; 6.4% vs. 23%, P = 0.003, respectively). In multivariate analysis, low T3 was found to be related to mortality at 1 year (OR: 2.6, 95% CI: 1.1-6.5, P = 0.02). In ROC analysis, free T3 had a good area under the curve (AUC) value for mortality at 1 year [AUC: 0.709 (95% CI: 0.619-0.799, SE: 0.0459)]. CONCLUSION: Low T3 is related to increased early and late mortality in NSTE-ACS patients. Free T3 levels may be used to identify NSTE-ACS patients with high mortality risk.

Prognostic impact of pleural effusion in acute pulmonary embolism.

Background Pulmonary embolism (PE) is a common and life-threatening condition associated with considerable morbidity and mortality. Pleural effusion occurs in about one in three cases; however, data on its prognostic value are scarce. Purpose To investigate the association between pleural effusion and both 30-day and long-term mortality in patients with acute PE. Material and Methods We retrospectively evaluated 463 patients diagnosed with acute PE using computed tomography pulmonary angiography (CTPA). Echocardiographic, demographic, and laboratory data were collected. The study population was divided into two groups: patients with and without pleural effusions. Pleural effusion detected on CT was graded as small, moderate, and large according to the amount of effusion. The predictors of 30-day and long-term total mortality were analyzed. Results Pleural effusions were found in 120 patients (25.9%). After the 30-day follow-up, all-cause mortality was higher in acute PE patients with pleural effusions than in those without (23% versus 9%, P < 0.001). Also, patients with pleural effusions had significantly higher incidence of long-term total mortality than those without pleural effusions (55% versus 23%, P < 0.001). In a multivariate analysis, pleural effusion was an independent predictor of 30-day and long-term mortality (odds ratio [OR], 2.154; 95% confidence interval [CI], 1.186-3.913; P = 0.012 and OR, 1.591; 95% CI, 1.129-2.243; P = 0.008, respectively). Conclusion Pleural effusion can be independently associated with both 30-day and long-term mortality in patients with acute PE.

The Endothelial Nitric Oxide Synthase (NOS3-786T>C) Genetic Polymorphism in Chronic Heart Failure: Effects of Mutant -786C allele on Long-term Mortality.

BACKGROUND: Nitric oxide plays an important role in the regulation of basal vascular tone and cardiac myocyte function. We investigated the NOS3-786T>C polymorphism in chronic heart failure (CHF) and its effects on long-term mortality. METHODS: Ninety-one patients with CHF who were referred to the Department of Cardiology of Siyami Ersek Cardiovascular and Thoracic Surgery Center for cardiopulmonary exercise testing between April 2001 and January 2004 and 30 controls were enrolled in this study. Patient were followed prospectively for a period of 1 to 12 years. RESULTS: Patients and controls were divided into three groups: TT, TC and CC, according to their NOS3-786T>C polymorphism. We noted that there was no significant difference in the genotype distribution between patients and controls. There was also no significant difference in endothelial nitric oxide synthase (eNOS) gene polymorphism between ischemic HF and nonischemic HF. During the follow-up period, 61 (67%) deaths occurred. The nonsurvivor group had lower left ventricular ejection fraction (LVEF) (p = 0.01), reduced peak oxygen consumption (p = 0.04) and were of older age (p = 0.001). Age, LVEF, peak oxygen consumption and genotype were found to be predictors of mortality (p < 0.05). Additionally, mortality was significantly increased in -786CC genotype patients compared to TT genotype patients (hazard ratio = 2.2; p = 0.03). By multivariate analysis, age and eNOS genotype were determined to be significant independent predictors of death. Additionally, Kaplan-Meier analysis confirmed that homozygote -786C genotype was associated with an increased risk of death (χ2 = 4.6, p = 0.03). CONCLUSIONS: Our findings showed that the NOS3-786T>C polymorphism was associated with an increased risk of mortality in patients with CHF.

Can mean platelet volume and neutrophil-to-lymphocyte ratio be biomarkers of acute exacerbation of bronchiectasis in children?

INTRODUCTION: Bronchiectasis (BE) is a parenchymal lung disease evolving as a result of recurrent lung infections and chronic inflammation. Although it has been shown in adult studies that mean platelet volume (MPV) and neutrophil-to-lymphocyte ratio (NLR) can be used as biomarkers of airway inflammation, knowledge is limited in the paediatric age group. The aim of our study is to investigate the potential of MPV and NLR as biomarkers that may indicate acute exacerbations of non-cystic fibrosis BE in children. MATERIAL AND METHODS: Children with non-cystic fibrosis BE (n = 50), who were followed in the division of Paediatric Pulmonology of our hospital between June 2010 and July 2015, were involved in the present retrospective cross-sectional study. Haemogram values during acute exacerbations and non-exacerbation periods, and a control group were compared. RESULTS: In children with bronchiectasis, the average leukocyte count (p < 0.001), platelet count (p = 0.018), absolute neutrophil count (p < 0.001), and NLR (p < 0.001) were higher, as expected, when compared with the control group. NLR values, in the period of acute exacerbation were significantly higher than the values of both the non-exacerbation periods (p = 0.02) and the control group (p < 0.001). In contrast, MPV values in the period of acute exacerbation did not exhibit a significant difference from those of non-exacerbation periods (p = 0.530) and the control group (p = 0.103). CONCLUSIONS: It was concluded that leukocyte count, platelet count, absolute neutrophil count, and NLR can be used to show chronic inflammation in BE, but only NLR and absolute neutrophil count can be used as biomarkers to show acute exacerbations.

Fragmented QRS on Admission Electrocardiography Predicts Long-Term Mortality in Patients with Non-ST-Segment Elevation Myocardial Infarction.

BACKGROUND: Early diagnosis and identification of high-risk non-ST elevation myocardial infarction (NSTEMI) is an important issue. Fragmented QRS (fQRS) complexes are defined as various RSR' patterns on 12-lead resting electrocardiography (ECG). Previous studies revealed that fQRS is related with increased ventricular arrhythmias and cardiovascular mortality. The relation between fQRS and mortality in acute coronary syndromes, mitral valve disease severity and structural heart disease has been shown in different studies. The aim of this study was to investigate relation between fQRS and long-term cardiovascular mortality in NSTEMI patients. METHODS: Patients who admitted to our emergency unit and diagnosed NSTEMI between 2012 and 2013, 433 patients were included prospectively. fQRS complexes determined in 85 patients. Patients were divided into two groups according to fQRS existence. All patients evaluated for their clinical, laboratory, electrocardiographic, and echocardiographic characteristics. Angiographic features of 315 patients who underwent coronary angiography was also recorded. In-hospital, 30-day and 12-month mortality was compared between these groups. RESULTS: Demographic characteristics and cardiovascular risk factors were similar in both groups except hyperlipidemia. GRACE risk score was higher in patients with fQRS and positively correlated with existence of fQRS. In hospital and 30-days mortality were similar but late mortality was higher in fQRS group. Predictors of late mortality were found to be age, heart rate, male sex in addition to fQRS. CONCLUSION: We found a relation between fQRS and late mortality. Fragmented QRS may be seen as a cautionary signal for extensive myocardial damage and thereby increased long-term mortality for patients with NSTEMI.

Relation of contrast nephropathy to adverse events in pulmonary emboli patients diagnosed with contrast CT.

OBJECTIVE: Limited data exist on the incidence of contrast induced nephropathy (CIN) and its impact on in-hospital prognosis of patients diagnosed with acute pulmonary embolism (APE) using contrast computerized tomography pulmonary angiography (CTPA). In this study, we examined the frequency of nephropathy after CTPA in APE patients and its link to in-hospital adverse outcomes. METHODS: This was a retrospective study of 189 patients (mean age 67+16years, 48% male) with APE who underwent CTPA. CIN was defined as a≥0.5mg/dl and/or ≥25% increase in serum creatinine levels >48hours after CTPA. Patients were divided into two groups according to the presence or absence of CIN to compare clinical characteristics, risk factors, and in-hospital adverse events. RESULTS: Twenty-four (13%) of the patients were diagnosed with CIN. Patients with CIN were older (73±17 vs. 67±15years, P=.01) and had higher rates of heart failure (17% vs. 6%, P=.04). Preexisting renal dysfunction and advanced age were found to be independent predictors of CIN (OR: 4.2, 95% CI: 1.5-11.9, P=.006; OR: 3.2, 95% CI: 1.1-9.8, P=.03 respectively). The in-hospital adverse event rate was significantly higher in patients with CIN (16.7% vs. 2.4%, P=.001). A multivariate analysis revealed CIN as an independent predictor of in-hospital adverse event rate (OR: 6.1, 95%CI: 1.2-29.3, P=.02). CONCLUSION: CIN is associated with a higher in-hospital adverse event rate in APE patients diagnosed using CTPA. This is first large study to focus specifically on CIN in patients diagnosed with APE using CTPA.

Sublingual vs. Oral Captopril in Hypertensive Crisis.

BACKGROUND: There are confusing data in literature regarding oral and sublingual captopril effects over blood pressure (BP) decrease. OBJECTIVES: In our study we compared oral and sublingual captopril effectiveness over BP decrease in patients admitted to our Emergency Department with hypertensive urgency. METHODS: Our study was conducted from January 2012 to January 2013 in patients with hypertensive urgency. In this cross-sectional study after two initial BP measurements, patients were identified as eligible for the study. An initial electrocardiogram was obtained and blood samples were drawn. A total of 212 patients were accepted as eligible for the study, and 25 mg of captopril was randomly given orally or sublingually; BP was measured at 10, 30, and 60 min. We selected the patients to the groups consecutively. A 25% reduction of initial BP 1 h after initiation of the treatment was accepted as an accomplishment. A second 25 mg of captopril was given if the target of 25% reduction of BP was not reached after the first tablet. Intravenous drugs were administered to the patients resistant to the captopril and these patients were excluded from the study. RESULTS: The 10-min systolic BP (SBP), diastolic BP, and mean BP (MBP) decrease was more prominent in the sublingual captopril group (p < 0.001). This decrease was statistically significant in the SBP and MBP at 30 min (p < 0.001), and no statistical difference was recorded at 60 min (p > 0.05). CONCLUSIONS: In our study, sublingual captopril was found to decrease BP more efficiently in the first 30 min, but this difference equalized at 60 min.

Effects of boric acid and 2-aminoethoxydiphenyl borate on necrotizing enterocolitis.

OBJECTIVE: The aim was to study the effects of boric acid (BA) and 2-aminoethoxydiphenyl borate (2-APB) on oxidative stress and inflammation in an experimental necrotizing enterocolitis (NEC) rat model. METHODS: Experimental NEC was induced in 40 newborn Sprague-Dawley rats by asphyxia and hypothermia applied in 3 consecutive days. Rats were subdivided into 4 subgroups as NEC, NEC+BA, NEC+2-APB, and controls. BA and 2-APB were applied daily before the procedure. Serum total antioxidant status, superoxide dismutase (SOD), tumor necrosis factor (TNF)-α, interleukin (IL)-6, and erythrocyte glutathione (GSH) levels were measured. Pathological changes for NEC in intestinal architecture were evaluated by a grading system. RESULTS: Pretreatment with BA and 2-APB resulted in a decrease in NEC incidence. In all of the NEC groups, decreased serum levels of GSH and SOD were measured. Boron limited GSH consumption but had no effect on SOD levels. Total antioxidant status levels were not statistically different among groups. In our experimental NEC model, BA, but not 2-APB, prevented the increase of TNF-α. Pretreatment with BA and 2-APB downregulated the activity levels of IL-6 in NEC. CONCLUSIONS: In the experimental NEC model, BA and 2-APB partly prevent NEC formation, modulate the oxidative stress parameters, bring a significant decrease in GSH consumption, and enhance the antioxidant defense mechanism, but have no effect on total antioxidant status. BA inhibits the hypoxia and hypothermia-induced increase in both IL-6 and TNF-a, but 2-APB only in IL-6. Boron may be beneficial in preventing NEC.

Efficacy of oral hydration in the prevention of contrast-induced acute kidney injury in patients undergoing coronary angiography or intervention.

BACKGROUND: Efficacy of intravenous (IV) volume expansion in preventing contrast-induced acute kidney injury (CI-AKI) is well known. However, the role of oral hydration has not been well established. The aim of this work was to evaluate the efficacy of oral hydration in preventing CI-AKI. METHODS: We prospectively randomized 225 patients undergoing coronary angiography and/or percutaneous coronary intervention in either oral hydration or IV hydration groups. Patients who have at least one of the high-risk factors for developing CI-AKI (advanced age, type 2 diabetes mellitus, anemia, hyperuricemia, a history of cardiac failure or systolic dysfunction) were included in the study. All patients had normal renal function or stage 1-2 chronic kidney disease. Patients in the oral hydration group were encouraged to drink unrestricted amounts of fluids freely whereas isotonic saline infusion was performed by the standard protocol in the IV hydration group. RESULTS: CI-AKI occurred in 8/116 patients (6.9%) in the oral hydration group and 8/109 patients (7.3%) in the IV hydration group (p = 0.89). There was also no statistically significant difference between the two groups when different CI-AKI definitions were taken into account. CONCLUSION: Oral hydration is as effective as IV hydration in preventing CI-AKI in patients with normal kidney function or stage 1-2 chronic kidney disease, and who also have at least one of the other high-risk factors for developing CI-AKI.

Detection of Helicobacter pylori in adenoid tissue by real-time polymerase chain reaction.

OBJECTIVES: This study aims to investigate the presence of Helicobacter pylori (H. pylori) using the real-time polymerase chain reaction (PCR) method in the adenoid tissues in children undergoing surgical operation due to adenoid hypertrophy. PATIENTS AND METHODS: Adenoid tissues of 23 children (8 girls, 15 boys; mean age 6.2 years; range 3 to 9 years) who were operated with the diagnosis of adenoid hypertrophy, tonsil + adenoid hypertrophy or tonsil + adenoid hypertrophy + serous otitis media in our clinic between January 2012 and April 2012 were examined. RESULTS: Of 23 patients, H. pylori was detected in the adenoid tissues of two (8.7%). Regurgitation was present in seven patients. However, no regurgitation was found in H. pylori-positive patients. CONCLUSION: In this study the presence of H. pylori in patients with adenoid hypertrophy has been demonstrated using PCR method. To be able to support the hypothesis that H. pylori has a place in etiology of adenoid hypertrophy, multicenter studies are warranted.

Percutaneous closure of an iatrogenic ventricular septal defect associated with transcatheter aortic valve implantation.

An 81-year-old man who had dyspnea was admitted to our hospital with a diagnosis of severe aortic stenosis. A transcatheter aortic valve implantation was successfully performed with a 29 mm Edwards Sapien XT valve using a transfemoral access. After the procedure, the echocardiography showed a restrictive ventricular septal defect (VSD) in the membranous septum. As the patient had no symptoms, it was decided to follow him up conservatively. However, he was readmitted within three weeks with symptoms suggestive of biventricular failure. A control echocardiography revealed a membranous VSD, 8 mm in size, right chambers dilatation with moderate tricuspid regurgitation, and systolic pulmonary artery pressure of 60 mm Hg. The previously deployed aortic valve was normal in function. The decision to perform a percutaneous VSD closure was made. The defect was then closed with a 10 mm muscular VSD occluder. During and after the procedure, there was no dysfunction in the bioprosthetic aortic valve. At the one-year follow-up, the patient was still asymptomatic.

The Mean Corrected TIMI Frame Count Could Predict Major Adverse Cardiovascular Events in Patients with Coronary Slow-Flow Phenomenon.

OBJECTIVE: The aim of the present study was to investigate the association between the mean corrected thrombolysis in myocardial frame count and major adverse cardiovascular events in patients with the coronary slow-flow phenomenon. METHODS: A total of 98 patients with coronary slow-flow phenomenon who met inclusion cri- teria from 2015 to 2020 were retrospectively included in the analysis. The patients were ranked according to their mean corrected thrombolysis in myocardial frame count values and were divided into quartiles based on those. Group 1 consisted of patients who had a mean corrected thrombolysis in myocardial frame count value >36.68 (third quartile), while group 2 consisted of patients who had a mean corrected thrombolysis in myocardial frame count value ≤36.68 (first quartile+second quartile). Mortality and non-fatal cardiovascular complications were compared between the groups. RESULTS: Mean follow-up duration was 3.93 ± 1.50 years. Recurrent chest pain and major adverse cardiovascular events increased in group 1 compared to group 2 (P ≤ .001, P ≤ .001, respectively). Hypertension (odds ratio 2.627, P=.033), hyperlipidemia (odds ratio 2.469, P = .028) and mean corrected thrombolysis in myocardial frame count (odds ratio 1.106, P = .002) were independent predictors of recurrent chest pain according to Cox regression analysis. Although older age (odds ratio 1.125, P=.011), hypertension (odds ratio 6.081, P=.026), hyperlipidemia (odds ratio 12.308, P = 0.019), and mean corrected thrombolysis in myocardial frame count (odds ratio 1.476, P = .001) were found to be significantly related with major adverse cardiovascular events in patients with coronary slow-flow phenomenon, only mean corrected thrombolysis in myocardial frame count (odds ratio 1.161, P = .021) was an indepen- dent predictor of major adverse cardiovascular events in Cox regression analysis. CONCLUSION: Higher mean corrected thrombolysis in myocardial frame count could predict major adverse cardiovascular events in patients with the coronary slow-flow phenomenon.

Atrial fibrillation-related acute myocardial infarction and acute mesenteric ischemia.

Atrial fibrillation-related synchronous thromboembolism of the mesenteric and coronary arteries is a rare event. This case report is about an 82-year-old male patient who presented to the emergency department with epigastric pain and who was diagnosed with ST-elevated myocardial infarction accompanied with acute mesenteric ischemia. To our knowledge, this is the first report of angiographic evidence of synchronous thrombus in both the arteries.

The Impact of Intravenous Fluid Therapy on Acid-Base Status of Critically Ill Adults: A Stewart Approach-Based Perspective.

One of the most important tasks of physicians working in intensive care units (ICUs) is to arrange intravenous fluid therapy. The primary indications of the need for intravenous fluid therapy in ICUs are in cases of resuscitation, maintenance, or replacement, but we also load intravenous fluid for purposes such as fluid creep (including drug dilution and keeping venous lines patent) as well as nutrition. However, in doing so, some facts are ignored or overlooked, resulting in an acid-base disturbance. Regardless of the type and content of the fluid entering the body through an intravenous route, it may impair the acid-base balance depending on the rate, volume, and duration of the administration. The mechanism involved in acid-base disturbances induced by intravenous fluid therapy is easier to understand with the help of the physical-chemical approach proposed by Canadian physiologist, Peter Stewart. It is possible to establish a quantitative link between fluid therapy and acid-base disturbance using the Stewart principles. However, it is not possible to accomplish this with the traditional approach; moreover, it may not be noticed sometimes due to the normalization of pH or standard base excess induced by compensatory mechanisms. The clinical significance of fluid-induced acid-base disturbances has not been completely clarified yet. Nevertheless, as fluid therapy may be the cause of unexplained acid-base disorders that may lead to confusion and elicit unnecessary investigation, more attention must be paid to understand this issue. Therefore, the aim of this paper is to address the effects of different types of fluid therapies on acid-base balance using the simplified perspective of Stewart principles. Overall, the paper intends to help recognize fluid-induced acid-base disturbance through bedside evaluation and choose an appropriate fluid by considering the acid-base status of a patient.

Are infants with food allergy candidates for respiratory allergy?

AIM: Allergic sensitization in infancy generally develops against food allergens. We aimed to investigate the frequency of aero-allergens sensitization at older ages in infants with food allergy. MATERIAL AND METHODS: This retrospective cross-sectional study was conducted in Dr. Behçet Uz Children's Allergy Clinic. Infants with confirmed IgE-mediated food allergy between January 1st, 2004, and December 31st, 2016, were evaluated for aero-allergen sensitivities through skin prick tests (SPT) after at least two years after diagnosis, and the data were compared with a healthy control group. RESULTS: A total of 187 cases, 87 of which were patients, were included in the study. The cause of food allergies was cow's milk only in 24 (27.6%) cases, egg only in 26 (29.9%) cases, both cow's milk and egg in 33 (37.9%) cases, fish only in two cases (2.3%), and both fish and egg in two (2.3%) cases. The mean age at which the aero-allergen SPT was performed was 65 (46-180) months in the patient group and 72 (48-132) months in the healthy control group. In the patient group, 39 (44.8%) had aero-allergen sensitization, whereas, in the healthy control group, five (5%) had aero-allergen sensitization. Aero-allergen sensitization was more frequent in the patient group (p<0.05). There was no statistically significant difference in the type and number of food allergies and the development of aero-allergen sensitization (p>0.05). CONCLUSION: In infants with food allergies, sensitization may develop with aero-allergens at an early age. Clinical follow-up of these patients may be important in terms of allergic respiratory diseases.

Gastrointestinal evaluation in colchicine-treated familial Mediterranean fever patients with chronic abdominal pain: cases series. / Evaluación gastrointestinal en los pacientes con fiebre mediterránea familiar con dolor abdominal crónico y tratados con colchicina: serie de casos.

The aim of the study to evaluate familial mediterranean fever (FMF) patients with chronic abdominal pain unresponsive to colchicine treatment. Forty-eight patients who diagnosed in our Pediatric Rheumatology clinics and suffering from abdominal pain despite colchicine treatment were include. All patients were referred to a pediatric gastroenterologist. The pain characteristics such as onset, duration and frequency wererecorded; gastrointestinal (GI) endoscopy was planned for differential diagnosis. MEFV mutation was determined in 46 patients. The median duration of treatment was 2.8 years. Approximately 60% of the patients suffered from abdominal pain every day or 2-3 times a week, in 73% of the cases it lasted less than three hours. Forty one patients underwent upper GI endoscopy. Gastroduodenitis is a common finding in persisting abdominal pain despite therapy of FMF patients. The patients with the highest disease severity scores had severe inflammation within the entire GI system.

El objetivo de este estudio fue evaluar a los pacientes con fiebre mediterránea familiar (familial Mediterranean fever, FMF) y dolor abdominal crónico resistentes al tratamiento con colchicina. Se incluyó a 48 pacientes diagnosticados en nuestro consultorio de reumatología pediátrica que tenían dolor abdominal a pesar del tratamiento con colchicina. A todos los pacientes se los derivó a un gastroenterólogo pediátrico. Se registraron las características del dolor, tales como aparición, duración y frecuencia; se planificó una endoscopía digestiva para obtener un diagnóstico diferencial. Se determinó la presencia de una mutación del gen MEFV en 46 pacientes. La mediana de la duración del tratamiento fue de 2,8 años. Aproximadamente el 60% de los pacientes tenían dolor abdominal todos los días o de dos a tres veces a la semana; en el 73% de los casos, duró menos de tres horas. A 41 pacientes se les realizó una endoscopía digestiva alta. La gastroduodenitis es un hallazgo frecuente en los pacientes con FMF y dolor abdominal persistente a pesar del tratamiento. Los pacientes con los puntajes más altos de severidad de la enfermedad tenían inflamación digestiva grave.
