Öğe Diagnosis of tularemia in a university hospital in Türkiye - 11-year evaluation(2023) Gezer, Yakup; Toplu, Sibel; Celık, Dondu; Ersoy, Yasemin; Bayindir, Yasar; Özden, Mehmet; Memişoğlu, FundaAim: Francisella tularensis is a Gram-negative coccobacillus and is the causative agent of tularemia, which is endemic in our country. The most common clinical form in Turkey is the oropharyngeal form. Sensitive lymphadenopathy is the most important finding, and fever, fatigue, and muscle and joint pain may occur in all clinical forms. Rodents such as rabbits, mice, and squirrels are the main reservoirs for humans, and the transmission is through contact with infected animal secretions and organs, contaminated water, and food. This study aimed to examine the socio-demographic, epidemiological, and clinical features of cases diagnosed with tularemia. Materials and Methods: Among the 583 patients whose serum samples were sent with a preliminary diagnosis of tularemia between 2011 and 2021, tularemia microagglutination test result (MAT) ?1/160 titer, 18 years and older cases were included in the study. Results: A total of 24 tularemia cases were detected, with a mean age of 43.3±17 years, 10 (41.7%) were male, and 14 (58.3%) were female. The most common symptoms and findings among the cases were lymphadenopathy (LAP) (95.8%), fatigue (66.7%), sore throat, and high fever (58.3%), and the most common epidemiological history was living in a rural area (91.7%) and dealing with animal husbandry (66.7%), and 18 (75%) cases were referred to as oropharyngeal tularemia. More than half of the cases were detected between October and March. Conclusion: Tularemia is one of the endemic diseases in our country, and the epidemio- logical history should be taken carefully and kept in mind in the differential diagnosis of lymphadenopathy. Since it is the first tularemia study conducted in Malatya, it shows the epidemiological characteristics of the region.Öğe Evaluation of CD4/CD8 ratio in treatment follow-up of patients with HIV diagnois in an infection clinic(2022) Gezer, Yakup; Toplu, Sibel; Yüksel, Mustafa; Köse, Adem; Memişoğlu, Funda; Ozden, Mehmet; Bayindir, YasarAbstract Aim: Antiretroviral therapy (ART) regimens used in the treatment of HIV are assumed to suppress the virus in plasma indefinitely and restore CD4 lymphocyte count. There is increasing evidence that a reversed CD4/CD8 ratio is associated with immune dysfunction, even in patients who have achieved virological suppression with ART and have elevated CD4 lymphocytes. The CD4/CD8 ratio has emerged as a guiding marker as an indicator of immunoactivation in HIV-infected patients. It was aimed to evaluate the CD4/CD8 ratio of HIV-diagnosed patients at baseline and at follow-up after ART regimen. Materials and Methods: A total of 150 patients were included in the study by retrospectively scanning the CD4/CD8 ratio at the initial and 24th week of follow-up in patients who were diagnosed with HIV and started treatment in the Infectious Diseases and Clinical Microbiology Clinic of the Hospital of the Medical Faculty between 2011-2021. ART treatment regimens were divided into three groups as nucleoside reverse transcriptase inhibitor (NRTI)+protease inhibitor (PI), NRTI+non-nucleoside reverse transcriptase inhibitor (NNRTI) or NRTI+ integrase strand transfer inhibitor (INSTI). Results: A total of 150 patients were included in the study. While the initial CD4/CD8 ratio of the patients was 0.36, it increased to 0.61 at the 24th week of treatment. Among the 144 patients whose baseline values were CD4/CD8<1, the rate of the ones who achieved CD4/CD8?1 value at week 24 after ART regimens was found as 13.2% (19/144). It was observed that the CD4/CD8 ratio in the group receiving INSTI was higher (15.1%) than those of the other groups. The undetectable HIV RNA level after treatment was significantly mostly observed in the group, receiving the integrase-based regimen, with 77.1%. With effective ART, CD4/CD8 normalization is higher in individuals with high CD4 T cell counts before treatment. There was a significant increase in the CD4/CD8 ratio in all three ART regimen groups. However, most of the patients who achieved a CD4/CD8 ratio ?1 were in the INSTI-based ART group. Conclusion: The CD4/CD8 ratio may contribute to clinical evaluation in long-term follow-up as a marker of immunological response in individuals treated with a diagnosis of HIV.Öğe Evaluation of the patient with lymphadenopathy: Is it always easy to reach the correct diagnosis?(2021) Köse, Adem; Doğan, Ahmet; Bayindir, Yasar; Ersoy, Yasemin; Özden, Mehmet; Memişoğlu, Funda; Toplu, SibelLymphadenopathy (LAP) is a common clinical problem in adult patients and should be thoroughly evaluated in a tertiary hospital to investigate its reasons. In this study,we aimed to present the demographic characteristics, etiology, diagnosis and follow-up results of the patients who applied with LAP symptoms and findings. This studywas designed to include adult patients with neck, armpit, or groin swelling accompanied by symptoms, such as fever, night sweats, weight loss, cough and sputum betweenJanuary 2010 and August 2017, retrospectively. Patients’ data were collected from electronic files. Patients were diagnosed using radiological, histopathological,bacteriological, serological and other microbiological methods. Two hundred-thirty patients were included in this study. The mean age was 43.12±17.06 SD in males and45.74±16.64 in females. On admission, the most common symptoms were night sweats (31%), fever (23%), weight loss (17%) and cough and/or sputum (13%) in orderof frequency. However, 16% of the patients were asymptomatic. In this study, 157 (68.26%) patients were diagnosed. Tuberculosis (n=76; 33%), malignancies (n=28,12.1%) and tularemia (N=14; 6.1%) were the most common diseases causing LAP that was most commonly located in the bilateral cervical chain. Lymphadenopathyshould be evaluated comprehensively concerning diagnosing or ruling out many diseases that must be treated necessarily. Knowledge and awareness of the diseases as acause of LAP may contribute to the early and correct diagnosis. Therefore, undiagnosed patients should be followed, and the institutions should develop policies for thispurpose, such as telemedicine applications.Öğe Is peritoneal dialysis prior to kidney transplantation a risk factor for ureteral stenosis after adult to adult live kidney transplantation(2020) Kutlutürk, Koray; Şahin, Tevfik Tolga; Çimen, Serhan; Dalda, Yasin; Gönültaş, Fatih; Doğan, Sait Murat; Toplu, Sibel; Ünal, Bülent; Pişkin, TurgutAbstract: Objective: Major urinary complications such as urinary leaks, stenosis or urinary tract infections after kidney transplantation can lead to graft or patient loss. The effect of peritoneal dialysis on post-kidney transplantation complications have been discussed but its effect on ureteral stenosis is unknown. In this study, it was aimed to analyze factors effecting major ureteral complications after living donor kidney transplantation and impact of peritoneal dialysis and double J-stents (JJ stents). Material and Methods: This study included 116 adult to adult living donor kidney transplant patients. Factors effecting major urologic complications after living donor kidney transplantation were analyzed. The donors were primary relatives of the recipients. Results: Major urologic complications after living donor kidney transplantation was 8/116 (6.9%). Urinary leak was present in 2 (1.7%) patients. Ureteral stenosis was encountered in 6 (5.2%) patients. Double J stents were used in 84 (72.4%) of the cases. The effect of JJ ureteral stent was not statistically significant for urinary leak, ureteral stenosis (p= 0.074, p= 0.470, respectively). A total of 29 (25%) patients had peritoneal dialysis before kidney transplantation. Preoperative peritoneal dialyses and bacteriuria after kidney transplantation were independent risk factors for ureteral stenosis in multivariate analysis (p= 0.013, and p= 0.010 respectively). Conclusion: In the guidance of the results of the present study, peritoneal dialysis prior to kidney transplantation and bacteriuria are independent risk factors for ureteral stenosis after living donor kidney transplantation. JJ stents have no effect on urologic complications after living donor kidney transplantation.Öğe Karaciğer nakli alıcılarında herpes simpleks virüs viremisinin tanısı, klinik görünümleri ve tedavi yönetimi(2021) Köse, Adem; Toplu, Sibel; Gönültaş, Fatih; Koç, Cemalettin; Yakupoğulları, Yusuf; Otlu, Barış; Şamdancı, Emine TürkmenAim: We aimed to evaluate the clinical variations, possible risk factors and results of diagnostic procedures in liver transplant (LT) recipients who suffered from Herpes Simplex Virus (HSV) viremia in the post-transplant period, despite Cytomegalovirus (CMV) prophylaxis. Material and methods: The data of 1100 LT recipients were evaluated retrospectively. HSV DNA RT-PCR detected in blood and vesicular fluid samples of the patients with active painful mucocutaneous vesicular lesions and patients with organ involvement who had biopsy and confirmed HSV viremia were included in the study. The 110 recipients diagnosed with HSV viremia were included. Results: In 110 recipients, total 130 HSV viremia episodes were observed over sixty months. HSV viremia rate was 11.8%. Of the 130 HSV episodes, 120 (92.3%) were mucocutaneous form of the disease. In 10 cases, there was a specific organ involvement. HSV-1 was detected in all of viremia episodes. Sixty-four (49.2%) episodes developed six months after the LT, 41 (31.5%) episodes developed between the 1st and 6th months after LT, and 25 (20.3%) episodes were observed within the first postoperative month. All episodes were treated successfully with different antiviral therapy modalities. Conclusion: Despite CMV prophylaxis performed, HSV viremia may be occurred as a wide range of clinical presentation in LT recipients. It can be seen at any time point after the LT. HSV DNA RT-PCR from serum samples may not be sufficient for diagnosis of viremia, therefore the analysis of the vesicular fluid or the biopsy from the organs may be necessary for supporting the diagnosis.Öğe Living Donor Kidney Transplantation: Why Potential Donors and Recipients do not Achieve it. Malatya Algorithm(Asoc Regional Dialisis Trasplantes Renales, 2020) Simsek, Arife; Dogan, Sait Murat; Gurbu, Huseyin; Ulutas, Ozkan; Toplu, Sibel; Turgut, Asli; Yildirim, Ismail OkanIntroduction: In some countries, organ donation is not widespread enough due to medical, cultural, ethical and socioeconomic factors. Living-donor kidney transplant constitutes the main source of kidney donation. Aim: To evaluate the causes of cancellation of living-donor kidney transplant and improve the effectiveness of transplant programs. Methods: Medical records of possible donors and recipients who were evaluated for living-donor kidney transplant at a tertiary medical center between November 2010 and September 2019 were reviewed retrospectively. Results: Evaluations were performed on 364 potential donors and 338 living-donor kidney transplant recipients; 207 of the latter (61.24%) underwent living-donor kidney transplant. Immune disorders represented the majority of cancellations (38.84%). Fifty-six donors (15.38%) were rejected mainly due to renal disorders (39%). Conclusion: Timely referral of patients to transplant centers must be guaranteed in order to overcome immune problems. Transplant centers should invest in programs adequate both for their resources and for their patients: paired kidney exchange, desensitization protocols, future research, etc.Öğe The relationship between caspase-1 related inflammasome expression and serum inflammatory cytokine levels during acute brucellosis(Kare Publ, 2019) Karaca, Gamze; Karaca, Zeynal Mete; Kayhan, Basak; Bayindir, Yasar; Kayabas, Uner; Toplu, Sibel; Elmasdag, SirvanOBJECTIVE: Brucellosis is a zoonotic disease caused by Brucella in domestic and wild animals. It also causes systemic diseases with the involvement of different parts of the human body. An efficient innate immune response is crucial to cure brucellosis with optimum antibiotic treatment. The inflammasomes are innate immune system receptors and sensors that regulate the activation of cysteine-dependent aspartate specific protease-1 (caspase-1) and caspase-1-induced cell death process known as pyroptosis. The aim of the present study was to investigate the expression levels of CASPASE-1 and associated inflammasomes AIM2, NLRP3, and NLRC4 to analyze their relationship with the inflammatory cytokine interleukin (IL)-1 beta, IL-18, and interferon-gamma (IFN-gamma) in peripheral blood samples of patients with acute brucellosis with healthy controls. METHODS: Peripheral blood samples were obtained from 20 healthy volunteers and 20 patients with acute brucellosis. RNA and serum samples were isolated to examine the expression levels of AIM2, NLRP3, NLRC4, and CASPASE-1 by real-time polymerase chain reaction, and IL-1 beta, IL-18, and IFN-gamma were measured by enzyme-linked immunosorbent assay. RESULTS: In the acute brucellosis group, AIM2 and NLRC4 expressions were significantly higher than in healthy volunteers. A significant increase on caspase-1 expression in patients with acute brucellosis was not observed. Serum IL-18 and IFN-gamma levels were significantly higher in patients with acute brucellosis than in healthy controls. CONCLUSION: Caspase-1-related inflammasomes are sufficiently activated to induce the secretion of cytokines, such as IFN-gamma and IL-18, to induce cellular immune response. Caspase-1 activation level should be investigated at different periods of disease in a group with high number of patients to understand the role of pyroptosis and caspase-1 in brucellosis.
