The aim of this study was to investigate the level of serum adenosine deaminase (ADA) and the total antioxidant capacity (TAC) in pulmonary tuberculosis (PTB), non-tuberculosis pulmonary disease (non-PTB) and healthy subjects. Materials and methods: Serum ADA activity was measured using the Giusti and Galanti method, and the total antioxidant capacity of plasma was determined by the ferric reducing ability of plasma (FRAP) test. Results: The serum ADA levels were significantly higher (P < 0.001) in pulmonary TB (PTB, 19.78 ± 7.09 U/L), as well as in non-PTB patients (14.78 ± 4.65 U/L) when compared to healthy controls (10.02 ± 1.99 U/L). The sensitivity and specificity were found to be 71.7% and 63.3%, respectively, in distinguishing PTB from non-PTB. In distinguishing PTB from healthy subjects, the sensitivity and specificity were 87% and 93.3%, respectively. The TAC was significantly lower in PTB (485.2 ± 190.0 µM) and non-PTB patients (588.3 ± 195.8 µM), when compared to the controls (784.3 ± 190.0 µM; P < 0.001). Plasma antioxidative activity decreased in PTB and non-PTB patients when compared to the controls. Conclusion: We concluded that serum ADA activity is not a useful test to differentiate pulmonary TB from other respiratory diseases.

Bacterial lipopolysaccharide (LPS) triggers synthesis of nitric oxide (NO) and superoxide (O_2^{.-}). O_2^{.-} can react with NO to produce the powerful oxidant peroxynitrite (ONOO-). The presence of 3-nitrotyrosine (3-NT) in tissues is often used as a marker of ONOO- production. Vitamin A, vitamin C, and melatonin are potent antioxidant molecules. We sought to clarify this issue by examining the effects of vitamin A (15,000 IU/kg/day), vitamin C (600 mg/kg/day), and melatonin (25 mg/kg) on 3-NT formation in heart tissue in a guinea pig model of LPS-induced endotoxemia. Materials and methods: A total of 75 animals were randomly divided into 5 …

Netherton syndrome (NS) is a rare genodermatosis characterized by autosomal recessive inheritance pattern, unknown etiology, ichthyosiform cutaneous changes, atopic diathesis, and alterations in the hair shaft. As a result of aging coupled with immune deficiency, clinical symptoms may vary. Herein, we present 2 siblings with the characteristic cutaneous symptoms of NS, albeit with some differences between the siblings. Materials and methods: Two sisters presented to our clinic with sparse and brittle hair along with pruritic, erythematous, and scaling cutaneous lesions. Both patients underwent a clinical examination and laboratory analyses. Results: Based on the clinical and laboratory findings, both patients were …
