RESUMO

OBJECTIVE: In this study, our objective was to present real-life data on the incidence of inflammatory bowel disease (IBD) among patients receiving secukinumab treatment. METHODS: The study consisted of 209 patients who had prior exposure to anti-tumor necrosis factor (TNF) or were biologically naive. Patients with a pre-existing history of IBD were excluded from the study. RESULTS: Of the 209 patients in the study, 176 (84.3%) had ankylosing spondylitis, while 33 (15.7%) had psoriatic arthritis. 112 (53.6%) patients had prior exposure to at least one anti-TNF treatment before initiating secukinumab. IBD developed in 10 (4.8%) of the 209 patients. The incidence of IBD among patients who initiated secukinumab as their first biologic agent was 1%. For patients who had previously received any anti-TNF treatment and subsequently transitioned to secukinumab, the incidence of IBD was 8% (p=0.018, odds ratio (OR): 8.38, 95% CI: 1.04-67.45). A mean of 3.67 months (±4.3) after anti-TNF use, whereas IBD symptoms developed in the biologically naive patient after 15 months. CONCLUSION: Our study observed IBD incidence in 4.8% of patients using secukinumab. Patients who initiated secukinumab after previous anti-TNF treatment exhibited a significantly higher rate and risk of developing IBD. The onset of IBD occurred earlier in these patients (mean 3.67 months), whereas a single case of IBD showed a longer duration (15 months). Further studies with larger patient numbers are warranted to provide a more comprehensive understanding of our findings.

Objetivo: En este estudio, nuestro objetivo fue presentar datos de la vida real sobre la incidencia de la enfermedad inflamatoria intestinal (EII) entre los pacientes que reciben tratamiento con secukinumab. Métodos: El estudio consistió en 209 pacientes que habían tenido una exposición previa al factor de necrosis antitumoral (TNF) o eran biológicamente naive. Los pacientes con antecedentes preexistentes de EII fueron excluidos del estudio. Resultados: De los 209 pacientes del estudio, 176 (84,3%) tenían espondilitis anquilosante, mientras que 33 (15,7%) tenían artritis psoriásica. 112 (53,6%) pacientes tenían exposición previa a al menos un tratamiento anti-TNF antes de iniciar secukinumab. La EII se desarrolló en 10 (4,8%) de los 209 pacientes. La incidencia de EII entre los pacientes que iniciaron secukinumab como primer agente biológico fue del 1%. Para los pacientes que habían recibido previamente algún tratamiento anti-TNF y posteriormente hicieron la transición a secukinumab, la incidencia de EII fue del 8% (p=0,018, odds ratio (OR): 8,38, IC del 95%: 1,04-67,45). Una media de 3,67 meses (±4,3) después del uso de anti-TNF, mientras que los síntomas de la EII se desarrollaron en el paciente biológicamente naive después de 15 meses. Conclusión: Nuestro estudio observó una incidencia de EII en el 4,8% de los pacientes que usaban secukinumab. Los pacientes que iniciaron secukinumab después de un tratamiento anti-TNF previo mostraron una tasa y un riesgo significativamente mayores de desarrollar EII. El inicio de la EII ocurrió antes en estos pacientes (media de 3,67 meses), mientras que un solo caso de EII mostró una duración más prolongada (15 meses). Se justifican más estudios con un mayor número de pacientes para proporcionar una comprensión más completa de nuestros hallazgos.(AU)

RESUMO

PURPOSE: Evaluation of the inflammatory response after Helicobacter pylori (Hp) eradication in patients with Familial Mediterranean Fever (FMF) during the non-attack period and determining whether there is a change in the ongoing inflammation during the non-attack period. MATERIALS AND METHODS: Sixty-four patients, who have not been eradicated for Hp in the last 2 years, diagnosed with FMF, and evaluated in the non-attack period, were included in the study. Hp eradication therapy was administered to patients who were found to be Hp-positive. C-reactive protein (CRP), high-sensitive C-reactive protein (hs-CRP), interleukin-6, interleukin-8, tumor necrosis factor-alpha, and serum amyloid A values were compared between the groups before and after eradication. RESULTS: CRP and hs-CRP levels were found to be statistically higher in the FMF group than in the control group. A statistically significant decrease was found in the values of CRP and hs-CRP, in the number of patients with attacks, and in attack frequency after eradication in the Infected Patients compared to the values before eradication. CONCLUSIONS: We determined a decrease in CRP and hs-CRP values, the number of patients with attacks, and attack frequency with the eradication of Infected Patients. In patients with FMF, in whom it has been proven by different studies that the inflammation continues during the non-attack period, it may be recommended to investigate the presence of Hp infection, which is thought to contribute to this inflammation and to give Hp eradication therapy to patients who are found positive to reduce the development of secondary complications caused by chronic inflammation.

RESUMO

OBJECTIVES: Paraneoplastic arthritis (PA) is one of the paraneoplastic syndromes. Both laboratory and clinical findings similar to rheumatological diseases can be seen. In this study, we aimed to present the clinical and laboratory findings, malignancy type, and pathological diagnoses of patients with paraneoplastic arthritis. METHODS: In a multicentre retrospective study, 92 patients with PA from the last 10 years were included in the study. RESULTS: Patients with PA and hematological malignancies detected the highest ratio of lymphomas (25,6%). The most common cancer detected in patients with solid malignancy and PA was lung cancer (41.5%). All malignant patients with PA had significant Anti-CCP positivity compared with the healthy control group (P= 0.014). CONCLUSION: As a result, although PA is a rare condition, it can be confused with many rheumatological diseases. The most commonly involved joint is the knee joint, followed by the ankle and hand-wrist. Autoantibody negativity, high LDH level, and arthritis unresponsive to treatment constitute important clues for diagnosis.

RESUMO

OBJECTIVE: Many treatment protocols are used in Helicobacter pylori eradication treatment within the framework of factors such as antibiotic resistance, drug side effects, patient compliance, and regional differences. MATERIALS AND METHODS: H. pylori was diagnosed with upper gastrointestinal system endoscopic biopsy in the Internal Diseases Gastroenterology Endoscopy Unit of Atatürk University Medical Faculty Hospital; a total of 229 patients over the age of 18 were evaluated prospectively by dividing them into 3 groups and applying 3 different H. pylori eradication treatment protocols. RESULTS: A total of 229 patients who completed the treatment were included in the study. H. pylori eradication was achieved in 186 patients and not achieved in 43 patients. The H. pylori eradication success of our study was found to be 81.2%. Among the 84 patients in group 1, while H. pylori eradication was achieved in 67 of them, it was not achieved in 17 patients. The eradication success of quadruple treatment with bismuth was 79.8%. Also, among the 68 patients in group 2, while H. pylori eradication was achieved in 55 patients, it was not achieved in 13. The eradication success of the 14-day hybrid treatment was 80.9%. Among the 77 patients in group 3, while H. pylori eradication was achieved in 64 patients, it was not achieved in 13. The eradication success of the 10-day sequential treatment was 83.1%. CONCLUSION: It is necessary to conduct studies to find the most successful eradication regimen in primary care treatment of H. pylori in our country, to determine the regional antibiotic resistance rates, to individualize the proton pump inhibitor treatment due to metabolism and resistance differences, to examine the factors that stop from achieving the desired eradication success, and especially to avoid unnecessary antibiotic use.

RESUMO

INTRODUCTION: Familial Mediterranean fever (FMF) is a hereditary auto-inflammatory disease characterized by recurrent fever and serosal inflammation. Anti-interleukin-1 (Anti-IL-1) treatments are recommended in colchicine resistant and/or intolerant FMF patients. This study aims to evaluate the efficacy of anakinra and canakinumab in FMF patients that are resistant/intolareted to colchicine or complicated with amyloidosis. METHODS: Between January 2014 and March 2019, 65 patients following-up at Sivas Cumhuriyet University (Medical Faculty Rheumatology-Internal Medicine Department) who were diagnosed with FMF according to the criteria of Tel-Hashomer were included in the study. The laboratory values and clinical features of patients and disease activities were recorded at least every 3 months, and these data were analyzed. RESULTS: Forty-one (63.1%) patients used anakinra (100 mg/day) and 24 (36.9%) patients used canakinumab (150 mg/8 week). The median duration of anti-IL-1 agents use was 7 months (range, 3-30). Fifteen (23.1%) cases were complicated with amyloidosis. Seven (10.8%) patients had renal transplantation. Overall, the FMF 50 score response was 96.9%. In the group that had a glomerular filtration rate (GFR) ≥ 60 ml/min/m2, the median proteinuria decreased from 2390 mg/day (range, 1400-7200) to 890 mg/day (range, 120-2750) (p = 0.008). No serious infections were detected, except in one patient. CONCLUSIONS: Anti-IL-1 agents are effective and safe in the treatment of FMF patients. These agents are particularly effective at reducing proteinuria in patients with GFR ≥ 60 ml/min/m2, but less effective in cases with FMF associated with arthritis and sacroiliitis. Large and long follow-up studies are now needed to establish the long-term effects of these treatments.

RESUMO

BACKGROUND: Burn trauma is a significant health problem that has physical, psychological, and economic repercussions on affected patients. The aim of this study was to present epidemiological and demographic characteristics of patients treated over an 8-year period at a reference burn treatment center located in the northeast of Turkey and serving a population of approximately four million people. METHODS: Each patient's medical record was reviewed, and demographic features, source of burns, place of residence, total body surface area (TBSA), surgical treatment, duration of hospital stay, and mortality rates were analyzed. RESULTS: The most frequent cause of burn was scalding from hot liquids (2013 cases, 74.2%). Freeze burn was observed in 16 (0.6%) cases due to climatic conditions of the region where our burn center is located. Grouping based on TBSA revealed that 88.7% patients had TBSA of 0%-15%, 8% patients had TBSA of 15%-30%, and 3.3% patients had TBSA ≥ %30.The most common microorganism was Pseudomonas aeruginosa. A total of 24 patients (0.9%; 8 males, 16 females) died, including 7 children and 17 adults. CONCLUSION: Removal of tandirs and replacement with high ovens, restriction of cheese and butter production under primitive circumstances, encouraging cheese and butter production via dairy farm systems, and raising people's awareness through training programs could greatly reduce the number of the burn accidents occurring in this region.

RESUMO

AIM: The purpose of this study was to investigate the relationship between the findings from liver biopsy and the serum angiotensin-converting enzyme (ACE) level to determine whether ACE might serve as a potential noninvasive sign of necroinflammatory activity in patients with Chronic Hepatitis B (CHB) infection. METHODS: A total of 54 CHB patients referred for liver biopsy were enrolled in the study. Serum ACE levels were determined photometrically with a kinetic test. RESULTS: The aspartate aminotransferase (AST), alanine aminotransferase (ALT), hepatitis B virus-deoxyribonucleic acid (HBV-DNA), histological activity index (HAI), and white blood cell counts were higher in patients with severe fibrosis, while albumin levels were low. The serum ACE levels showed a statistically significant correlation with HBV-DNA, HAI score, and ALT-AST levels. DISCUSSION: In this study, a statistically significant relation between serum ACE levels and HAI scores was observed. This represents the first analysis to compare necroinflammation of the liver and serum ACE levels. There may be some explanations that the suppression of hepatocyte growth factor (HGF) by Angiotensin II and increased inflammatory damage might be a reason for the correlation between HAI and ACE. Serum ACE levels, HBV-DNA levels, and serum transaminase levels might be used together as noninvasive markers for the prediction of necroinflammation in CHB patients.

RESUMO

Abstract Helicobacter pylori infection is usually acquired in early childhood and it can persist throughout life without antibiotic treatment. This study aimed to compare the accuracy of the noninvasive H. pylori Stool Antigen Test-applied on the stool samples with the invasive gold standart Rapid Urease Test-applied on the gastric biopy samples of patients with upper gastrointestinal complaints. After endoscopy, biopsy and stool specimens were taken in 122 patients. The infection was detected with rapid urease test which is accepted as gold standart test. Rapid, one-step H. pylori card test was applied to all patients stool specimens. In this study 106 of the 122 patients (86.8%) were positive for H. pylori infection, while 16 of the 122 patients (13.2%) were negative. H. pylori card test was negative in 13 of the 16 patients and was positive in 98 of the 106. The sensitivity, specifity, positive and negative predictive values were 92.45%, 81.25%, 97.02%, and 61.90%, respectively. H. pylori card test is rapid, easy, noninvasive and inexpensive methods for detection H. pylori infection. This test showed high sensitivity and specificity. Additionally, it may be a good alternative to invasive tests for the detection of H. pylori infections especially in children.

RESUMO

OBJECTIVE: To assess the effectiveness of resistin in predicting the severity of acute pancreatitis. METHODS: Patients with acute pancreatitis who presented at the Gastroenterology Clinic, Erzurum Education and Research Hospital, Turkey were enrolled in this prospective study. White blood cell (WBC), C-reactive protein (CRP) and resistin levels were measured on admission and at 24 h, day 3 and day 7 following admission, along with other blood parameters. Patients were divided into two groups: mild acute pancreatitis and moderate/severe acute pancreatitis. RESULTS: Of 59 patients with acute pancreatitis (mild, n = 37; moderate/severe, n = 22), significant between-group differences were found in terms of resistin and CRP levels. Receiver operating curve analysis showed that resistin levels were better for predicting severe cases of acute pancreatitis than CRP or WBC levels on day 3 (area under the curve [AUC], 0.88 versus 0.81 and 0.63, respectively). Resistin levels on day 3 were better than CRP levels for predicting necrosis development (AUC, 0.70 versus 0.69, respectively). CONCLUSIONS: Resistin may represent a new, effective indicator to predict the severity of acute pancreatitis and presence of necrosis in patients with acute pancreatitis.

RESUMO

BACKGROUND: Oxidative liver injury occurring with methotrexate restricts its use in the desired dose. Therefore, whether or not thiamine and thiamine pyrophosphate, whose antioxidant activity is known, have protective effects on oxidative liver injury generated with methotrexate was comparatively researched in rats using biochemical and histopathological approaches. MATERIAL/METHODS: Thiamine pyrophosphate+methotrexate, thiamine+methotrexate, and methotrexate were injected intraperitoneally in rats for 7 days. After this period, all animals' livers were excised, killing them with high-dose anesthesia, and histopathologic and biochemical investigations were made. RESULT: Biochemical results demonstrated a significant elevation in level of oxidant parameters such as MDA and MPO, and a reduction in antioxidant parameters such as GSH and SOD in the liver tissue of the methotrexate group. Also, the quantity of 8-OHdG/dG, a DNA injury product, was higher in the methotrexate group with high oxidant levels and low antioxidant levels, and the quantity of 8-OHdG/dG was in the thiamine pyrophosphate group with low oxidant levels and high antioxidant levels. In the thiamine and control groups, the 8-OHdG/dG rate was 1.48 ± 0.35 pmol/L (P>0.05) and 0.55 ± 0.1 pmol/L (P<0.0001). Thiamine pyrophosphate significantly decreased blood AST, ALT and LDH, but methotrexate and thiamine did not decrease the blood levels of AST, ALT and LDH. Histopathologically, although centrilobular necrosis, apoptotic bodies and inflammation were monitored in the methotrexate group, the findings in the thiamine pyrophosphate group were almost the same as in the control group. CONCLUSIONS: Thiamine pyrophosphate was found to be effective in methotrexate hepatotoxicity, but thiamine was ineffective.

RESUMO

The presence of liver disease in patients with progressively worsening insulin resistance may not be recognized until patients develop manifestations of the metabolic syndrome such as diabetes, hypertension, hyperlipidemia, and vascular disease. It was aimed to investigate whether three angiotensin II type 1 receptor antagonists (ARBs) (olmesartan, losartan, and valsartan) had preventive effect against hepatic fibrosis and this was a common characteristic among ARBs. In current study, 25 adult male rats were used and divided into five groups: the non-diabetic healthy group, alloxan induced diabetic (AID) control group, AID losartan group, AID valsartan group and AID olmesartan group. According to numerical density of hepatocytes, significant difference was found between the non-diabetic healthy group and diabetic control group. All treatments groups were significant when compared to diabetic control group. In diabetic control group it was examined swelling, irregular cristae arrangement in some of mitochondria. It was also determined mitochondria membrane degeneration in some areas of section profiles. In diabetic rats treated with losartan group, there were necrotic hepatocytes. In diabetic rats treated with valsartan group, predominantly, findings were similar to losartan group. In diabetic rats treated with olmesertan group, plates of hepatocytes were quite regular. There were hardly necrotic cells. Not only other organelles such as RER, SER and lysosom but also mitochondrial structures had normal appearance. In the diabetic control group electron microscopy revealed edema in both the cytoplasm and perinuclear area and the nuclear membranes appeared damaged. In conclusion, it was established that the most protective ARB the liver in diabetic rats was olmesartan, followed by losartan.

RESUMO

DRESS syndrome is a life-threatening adverse reaction characterized by skin rashes, fever, leukocytosis with eosinophilia or atypical lymphocytosis, lymph node enlargement, and liver or renal dysfunctions. DRESS syndrome related to valproic acid use is very rarely observed. We present a case of DRESS syndrome induced by sodium valproate, which developed and progressed fatally in a brucellosis patient with a positive c-ANCA test. A 19-year-old female patient presented with fever, cough, jaundice, and rash all over her body. Brucella Coombs test was positive at 1:1280 titers, and the Rose Bengal test was also positive. The involuntary movements were thought to be due to chorea, and the patient was started on sodium valproate 500 mg 2 1, as well as streptomycin 1 g flk 1 1 and tetradox capsules 2 1 for the brucellosis and was discharged. DRESS syndrome was suspected in the patient, and she was taken off sodium valproate and tetradox; N-acetylcysteine, ceftriaxon, prednizolone, and support treatment were started. When sodium valproate is used on its own, it carries no risk of inducing DRESS syndrome. However, in the case presented, another co-morbidity such as brucellosis and c-ANCA positivity was present. We believe that the presence of further co morbidity not yet reported in literature is important from the perspective of the risk of valproate-induced DRESS syndrome. Therefore, if sodium valproate treatment is to be started in patients, especially those with co morbidity, they must be closely monitored with clinical and laboratory observations. At the slightest suspicion of DRESS syndrome, all medication should be ceased immediately and the patient should be placed under continuous observation.

RESUMO

Abdominal cystic lymphangiomas are rare congenital benign malformations of the lymphatic system. To the best of our knowledge, only 6 mesenteric calcified cystic lymphangiomas have ever been reported. We herein describe a woman who presented to our hospital with stomachache that had been continuous for approximately 8 months. An abdominal computed tomography showed a cystic lesion. In the exploration, the cyst was totally excised. Based on the histomorphological data, a case of "calcified cystic lymphangioma" was diagnosed. Although mesenteric lymphangiomas are rare, especially in adults, they should be considered as a possible cause of abdominal pain. Treatment is surgical with resection of the mass, sometimes including resection of adjacent bowel.
