Association of Paraoxonase Activity and Atherosclerosis in Patients With Chronic Hepatitis B
(Makerere Univ, Fac Med, 2012) Karsen, H.; Binici, I; Sunnetcioglu, M.; Baran, A., I; Ceylan, M. R.; Selek, S.; Celik, H.
Background: The hepatitis B virus is a significant pathogen that causes cirrhosis, and hepatocellular cancer as a result of the damage it causes to liver cells. Its infection affects more than 400 million people globally. Although there is an effective vaccine and treatment methods, almost 1, 000, 000 people die every year. Objective: To investigate paraoxonase and arylesterase activities along with oxidative status parameters and serum lipid levels, and to find out if there is any increased susceptibility to atherogenesis. Methods: Thirty-four subjects with chronic hepatitis B and 39 healthy subjects as control were enrolled in the study. Age, body mass index and gender, Serum Triglycerides (TG), High-density Lipoprotein (HDL) and Low-Density lipoprotein (LDL) levels, serum paraoxonase-1 and arylesterase activities were determined. Oxidative and antioxidative statuses were evaluated by measuring serum-free sulfhydryl groups, lipid hydroperoxide levels, total antioxidant capacity, total oxidant status, and oxidative stress index. Results: Serum TG and LDL levels were higher while serum HDL levels were lower in patients with chronic hepatitis B than in controls but the differences did not reach statistical significance. Serum paraoxonase-1 and arylesterase activities, plasma free sulfhydryl groups, and total antioxidant capacity were significantly lower in patients than in controls (p=0.018, p=0.005, p<0.001, p=0.037 respectively), while lipid hydroperoxide, total oxidant status, and oxidative stress index were significantly higher (for all p<0.001). Conclusion: The diminution in the paraoxonase-1 and arylesterase activities could contribute to the accelerated development of atherosclerosis in patients with chronic hepatitis B.
A Case of Brucellosis Lymphadenitis Mimicking Scrofuloderma
(TIP ARASTIRMALARI DERNEGI, 2007) Karsen, H.; Karahocagil, M.K.; Akdeniz, H.; Sünnetçioǧlu, M.; Evirgen, Ö.
Brucellosis is a zoonotic disease, which may be manifested by multisystemic involvement. While the complications related to musculoskeletal and gastrointestinal system are frequently seen, those related to the other systems are rarely encountered. In this paper, we present a brucellosis lymphadenitis case in the right side of the neck in a 20 years old female patient, presenting with a mass formation in the soft tissue mimicking scrofuloderma, with dimensions of 10x6x4 cm. Especially in endemic areas, brucellosis lymphadenitis should also be remembered in addition to scrofuloderma.
Cutaneous Anthrax in Eastern Turkey
(Wiley, 2008) Karahocagil, M. K.; Akdeniz, N.; Akdeniz, H.; Calka, Oe.; Karsen, H.; Bilici, A.; Evirgen, Oe.
Background. Anthrax is a zoonotic disease diminishing worldwide. Although a very rare disease in developed countries, anthrax is still endemic in developing countries. Aim. To evaluate the clinical history and features, treatment and outcome of our patients with anthrax and emphasize the importance of the disease in our region. Method. In this study, the records of all patients diagnosed with cutaneous anthrax admitted to Yuzuncu Yil University Medical Faculty between March 2002 and March 2007, were reviewed, and data on age, gender, occupation, clinical symptoms and findings, location and type of lesions, clinical history, laboratory findings, treatment and outcome were recorded. Results. There were 85 patients [46 (54.1%) male, 39 (45.9%) female; mean age 30.6 years, range 6-72]. All the patients had a history of contact with infected animals or animal products. The infectious agent was found using direct examination of Gram-stained smears from 17 patients (20%), and Bacillus anthracis was isolated from vesicle fluid cultures from 11 patients (12.9%). Diagnosis was based on clinical findings in the remaining 57 patients (67.1%). All patients, except for two with respiratory tract obstruction, made a full recovery. Conclusion. Anthrax continues to be an endemic disease in Turkey, and should be considered in patients with a relevant contact history having a painless ulcer and vesicular skin lesions surrounded by a zone of oedema. Gram staining and simple culture methods are useful aids to diagnosis, but diagnosis may have to be based on clinical grounds in the majority of patients.
Evaluation of Oxidative Status in Patients With Fasciola Hepatica Infection
(Makerere Univ, Fac Med, 2011) Karsen, H.; Sunnetcioglu, M.; Ceylan, R. M.; Bayraktar, M.; Taskin, A.; Aksoy, N.; Erten, R.
Background: F. hepatica infection is rare and mostly subclinical. Migration of juvenile forms of F. hepatica into the host's liver is accompanied by an inflammatory reaction followed by fibrosis and cirrhosis. Objective: The aim of this study was to evaluate oxidative status by using a novel automated method in patients with Fasciola hepatica. Methods: Twenty two patients with a diagnosis of F. hepatica and 26 healthy volunteers were enrolled in the study. Their Total antioxidant capacity status (TAC), total oxidant status (TOS) and catalase were measured in them and oxidative stress index (OSI) was calculated. These measurements were also taken for the control group and the values were compared. Results: Plasma levels of total TOS and OSI were significantly increased in patients as compared with healthy controls (P<0.001, P<0.001, P=0.001, P=0.008) respectively. In contrast, TAC level was significantly lower in patients as compared with controls (p<0.05). There was no significant difference between the catalase results of the two groups (p>0.05). Conclusion: Total oxidative status and OSI were increased and total antioxidative status capacity was decreased in patients with F. hepatica infeciton. A high oxidative stress occurs during F. hepatica infection, which may cause severe damage in both the liver.
Herpes Simplex Encephalitis
(2010) Karsen, H.; Demir, C.; Karahocagil, M.K.; Sünnetcioǧlu, M.; Akdeniz, H.
We presented four cases diagnosed with Herpes simplex virus encephalitis of those treated in our clinic in 2006 one of whom died, one recovered without any sequels. Two cases were left with advanced motor mental sequel. In this paper, clinical and laboratory findings along with diagnosis and treatment of Herpes simplex virus encephalitis were discussed.
Investigation of the Predictive Value of Amino Acids for Tuberculous Meningitis, Aseptic Meningitis and Bacterial Meningitis
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Binici, I.; Huyut, Z.; Alp, H.H.; Akbay, H.I.; Karsen, H.; Parlak, M.; Akmeşe, Ş.
In our study, we aimed to detect amino acid changes, if any, by comparing the levels of amino acids in cerebrospinal fluid (CSF) samples of patients with aseptic, bacterial, and tuberculous meningitis and control groups. Patients diagnosed with aseptic meningitis (n=41), tuberculous meningitis (n=21), bacterial meningitis (n=41) and a control group consisting of 64 individuals with similar gender and age characteristics were included in the study. 2 mL of cerebrospinal fluid specimens were obtained from all patients and control group and sto red at-80 °C until the study day. The amino acid measurements were performed using commercially available liquid chromatography-tandem mass spectrometry method (LC-MS / MS) kits. When we investigated amino acids levels in all groups, the levels of 1-methyl histidine, alanine, asparagine, histidine, isoleucine, lysine, methionine, norvaline, ornithine, phenylalanine, proline, sarcosine, threonine, tyrosine, valine in the aseptic, tuberculosis and bacterial meningitis groups were statistically higher than t hose of the control group. The levels of all amino acids except cystine, glutamic acid, homo-citrulline, and taurine in the patients with aseptic meningitis were statistically significantly higher than in the control group. The levels of all amino acids ex cept homocitrulline, and tryptophan were statistically significantly higher in the patient group with tuberculous meningitis than in the control group. The levels of all amino acids except glutamic acid were statistically significantly higher in the patient group with bacterial meningitis than in the control group. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi.
