Abstract
Background and Objective: Diagnosis of latent tuberculosis infection (LTBI) by tuberculin skin test (TST) is accompaind with limitations. A few documented data exist regarding the performance of serology tests for LTBI diagnosis in HIV infection. The aim of this study was to determine LTBI prevalency and compare TST results and IgM antibodies against M.tuberculosis antigens (IAMA) for the diagnosis of LTBI in HIV infected individuals. Materials and Methods: In this discriptive study, sixty two HIV infected subjects were chosen randomly from an addict treatment center in Ahvaz southwest Iran during 2008. The patients underwent TST, using 5 TU of purified protein derivative, and IAMA was measured. Data were analyzed using SPSS-15 software and Chi-Square test. Results: From 62 studied cases, 34 (54.8%) had positive result for TST, whereas 6 (9.7%) had positive IAMA. LTBI was diagnosed in 37 (59.7%) by either TST or IAMA. Overall concordance between TST and IAMA was 45.2%. In subjects with positive test by either TST or IAMA, only 4.8% had positive test by either diagnostic procedure. Discordant results were found in 54.8% of subjects. Positive results for both diagnostic methods in subjects with above and below 200 CD4-cell/mm3 did not show any significant differences. Conclusion: This study showed that LTBI prevalence among HIV infected individuals among addict patients, in this region is higher than other parts of the world. Also TST is a useful test for LTBI diagnosis is preferable to IAMA method.

Abstract
Background and Objective: HIV treatment influences the global health and finding new compounds against HIV virus is increased. This study was done to evaluate anti-HIV activity of 8-phenyl-4-quinolone derivatives containing different substituents at position 3.
Methods: In this descriptive study, single cycle replicable (SCR) HIV Virions were produced by co-transfecting HEK 293T cells with pmzNL4-3, pSPAX.2, pMD2.G plasmids. HeLa cells were infected with the SCR virions and then inhibit of virus replication by compounds were measured by p24 Antigen with ELISA kit. The cytotoxicity of these compounds on HeLa cells were measured by XTT method.
Results: All compounds including NPZ_4F, NPZ-2F, NPZ-4CL and NPZ-2CL had the best inhibitory effect at a concentration of 100µM with the inhibition rate of respectively 51%, 48%, 33%, and 25%, respectively. The compounds of NPZ-4F and NPZ-2CL had negligible cellular toxicity and have inhibited HIV replication at the highest concentration. This issue can make them a valuable compound since they are better compounds in therapeutic terms, which at a suitable concentration, they have the lowest rate of cellular toxicity and highest power to inhibit HIV replication.
Conclusion: Novel compounds derived from 8-phenyl-4-quinolone containing different substituents at position 3 can prevent HIV replication which is capable of high anti-viral and low cellular toxicity and suitable candidates for further investigation in antiviral studies.

Abstract
Background and Objective: Prisoners are among the high risk population for contagious infections such as HIV (Human Immunodeficiency Virus), HBV (Hepatitis B Virus), HCV (Hepatitis C Virus), TB (Tuberculosis), and other dangerous diseases. In spite of other countries in the world, data about the prevalence and risk factors for infectious diseases among prisoners are spars in Iran. The aim of this study was to determine the prevalence of HBV, HCV and TB coinfections among male prisoners suffering from HIV.
Methods: In this descriptive-analytical study, 100 HIV patients were selected. Microscopic examination (acid fast staining) was applied on sputum specimens and serological (HBsAg, anti- HCV) and molecular (Real time PCR and DNA sequencing) investigations carried out on patient’s sera.
Results: Among 100 prisoners affected with HIV, the prevalence of HCV, HBV and TB infections were 45%, 3%, and 9%, respectively. All HBV positive cases were genotype D, subgenotype ayw2. Among the HCV positive subjects, 34 (75.5%) and 11 (24.5%) were genotype 1a and genotype 3a, respectively. There was no significant relation between age, CD4 and transmission route of HCV in male prisoners affected with HIV. Drug injection was the main route for the acquisition of HCV, HBV infections.
Conclusion: This study showed that a high prevalence of HCV and TB infections among male prisoners affected with HIV.
