Serum cytokine levels in patients with acute brucellosis and their relation to the traditional inflammatory markers

The number of clinical studies on gamma interferon (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha) and interleukin-4 (IL-4) in human brucellosis is limited. The present study was focused on IFN-gamma, TNF-alpha and IL-4 levels in acute brucellosis cases, in the acute phase and at the end of the treatment. The relation of these cytokines to traditional inflammation markers was also investigated. The study included 27 cases of acute brucellosis and 20 healthy volunteers who had no complaints. It was found that mean IFN-gamma and TNF-alpha levels, CRP (C-reactive protein) levels and ESR (erythrocyte sedimentation rate) values were significantly higher in acute brucellosis cases as compared to post-treatment values and values measured in the control group. In addition, IFN-gamma and TNF-alpha levels measured in the acute phase correlated with the increase in CRP levels and ESR values. Our results confirmed that IFN-gamma and TNF-alpha are involved in the pathophysiology of brucellosis and are closely related to the inflammatory activation of the disease. In view of the present findings, it is suggested that IFN-gamma and TNFalpha may be used for monitoring brucellosis.

Toxocara Seroprevalence in Schizophrenic Patients in Turkey

Purpose To investigate the seroprevalence of toxocariasis in patients diagnosed as schizophrenia. Patients and Methods Ninety-eight schizophrenic patients hospitalized at The Elazığ Psychiatric Hospital were included in the study. Anti-Toxocara IgG and/or IgM antibodies were determined by using commercial Toxocara canis IgG and/or IgM ELISA kit. Results Seropositivity for T. canis was detected in 45 (45.9%) of 98 patients and 2 (2.0%) of 100 control subjects the difference was statistically significant (p < 0.001). The seroprevalence was 40.4% (19 cases) and 51.0% (26 cases) for female and male subjects, respectively (p = 0.3). When the seropositive and seronegative schizophrenic patients were compared with respect to the age group environment they were living in, occupation period of follow up and number of hospitalizations, there were no differences between the two groups (all, p > 0.05). Conclusion In conclusion, the schizophrenic state seems to present a high risk for Toxocara infection in Turkey.

Effects of Ibuprofen on the physiology and outcome of rabbit endotoxic shock

BackgroundDespite major developments in the management of septic shock, the mortality rate had progressively increased. Ibuprofen has been shown to have beneficial physiological effects when used as a treatment. However, there are conflicting results with respect to survival. This study aims to investigate the effect of ibuprofen on vital functions, various physiological parameters and survival during endotoxic shock in rabbits.MethodsTwenty-eight New Zealand rabbits were randomly separated into four groups. The first group received only saline, the second was given 2 mg/kg intravenous endotoxin at t0, the third received 30 mg/kg ibuprofen 30 minutes after endotoxin administration, whilst the fourth group received ibuprofen 30 minutes before the endotoxin. Respiratory and heart rate, mean arterial blood pressure and rectal temperature were recorded. Complete blood counts were performed and thromboxane B2 was measured every 30 minutes for the first two hours, and then hourly over the course of the experiment. Urine samples were collected at the same time points for the measurement of prostaglandin E2.ResultsIbuprofen was found to improve respiratory rate, heart rate, and arterial pressure. However, it did not improve the negative effects of endotoxin on body temperature, haematocrit values, white blood cell count, and thrombocyte number. Thromboxane B2 levels in group IV were significantly lower than in the other groups, and the increase started at a later timepoint. In ibuprofen-treated animals, Prostaglandin E2 levels stayed low for at least 90 minutes, but started to rise thereafter. While the average survival in Group II animals was 192.9 ± 46.9 minutes, those of groups III and IV were 339.1 ± 33.5 minutes (p < 0.05) and 383.0 ± 39.6 minutes (p = 0.01), respectively.ConclusionsIbuprofen appears to increase survival in endotoxic shock-induced animals. Therefore, it may be helpful for the prophylaxis and treatment of patients with, or who are likely to develop, septic shock.

Hepatocyte growth factor (HGF) in patients with acute brucellosis

In this prospective study, we investigated the serum levels of hepatocyte growth factor (HGF) and C-reactive protein (CRP) before and after the treatment of patients with acute brucellosis. The study comprised 58 patients with acute brucellosis and 30 healthy volunteers. Pre-treatment serum HGF levels of 58 patients with acute brucellosis (1548.6±220.1) were significantly higher than levels of the control group (401.4±69.7) (p<0.001). Serum levels of HGF and CRP significantly decreased at the end of the treatment period (p<0.001). Post treatment, levels did not differ from those of the control group (p>0.05). Serum HGF levels of patients with acute brucellosis correlated to CRP and ALT levels (r: 0.922, 0.752; p<0.001, respectively). Our findings suggest that serum HGF levels may be used as a supplementary marker to evaluate the effectiveness of the treatment in patients with acute brucellosis.

Comparison of Children and Adults with Tuberculous Meningitis in Elazig, Turkey

Retrospective evaluation of 16 cases of tuberculous meningitis revealed that BCG vaccination and tuberculin positivity were rare in pediatric as well as adult patients. Children with disease had developmental retardation and a high rate of maternal illiteracy as compared to normal controls.

An Investigation of Candida Species in Patients with Oral Leukoplakia

In 1966, Cawson 1 described the distinctive clinical and histological features of a form of oral candidosis presenting itself as a leukoplakia. This was termed chronic hyperplastic candidosis or candidal leukoplakia 2.
