Objective: To identify the frequency of syphilis among Iranian HIV-positive patients. Methods:A cross-sectional study on the prevalence of syphilis and HIV co-infection among 450 patients diagnosed with HIV infection was conducted between 2004 and 2008 at Imam Khomeini hospital, Tehran, Iran. The lab tests including CD4 cell count, cerebrospinal fluid, veneral disease research laboratory (VDRL), fluorescent treponema antibody-absorption (FTA-Abs) and viral load were performed for all the patients. Data regarding medical history and their demographics were also collected. Results: Of all 450 HIV-positive patients, 24 (5.3%) had a positive VDRL test and only two men had a FTA-Abs positive test which means 0.45% of them had a definite co-infection of syphilis. 65.3% of the HIV-positive patients were injection drug users that the co-infection prevalence of them was 0.7%. We did not find any patient with neurosyphilis. Conclusions: Considering the increasing prevalence of HIV and also extensive use of highly active antiretroviral therapy in developing nations, the diagnosis of syphilis should be timely established using screening tests among such patients.

After its identification in 1980s, HIV has infected more than 30 million people worldwide. In the era of highly active anti-retroviral therapy, anti-retroviral drug resistance results from insufficient anti-retroviral pressure, which may lead to treatment failure. Preliminary studies support the idea that anti-retroviral drug resistance has evolved largely as a result of low-adherence of patients to therapy and extensive use of anti-retroviral drugs in the developed world;however, a highly heterogeneous horde of viral quasi-species are currently circulating in developing nations. Thus, the prioritizing of strategies adopted in such two worlds should be quite different considering the varying anti-retroviral drug resistance prevalence. In this article, we explore differences in anti-retroviral drug resistance patterns between developed and developing countries, as they represent two distinct ecological niches of HIV from an evolutionary standpoint.

Objective:To determine the prevalence of HIV infection among homeless men and women and the related risk behaviors in Tehran, Iran.
Methods: In 2007-2008, Tehran municipality stacked up 10 657 homeless men and women for assessment of HIV and began collaboration with Iranian Research Center for HIV/AIDS (IRCHA) departments to conduct HIV infection prevalence surveys in homeless populations. The results were analyzed for associations with demographic information, family support, status of drug abuse and relation with family and friends.
Results:Overall HIV prevalence was 1.7%(95%confidence interval 1.4-1.9). Factors independently associated with HIV infection included history of using drugs [AOR 8.15 (4.86-13.67)], older age [AOR 1.80 (1.08-2.99) for 40- 55 yr], occupation [AOR 1.64 (1.19-2.24) for unemployed], and no relation with family [AOR 1.82 (1.30-2.54)].
Conclusions: This study supports the idea that injection drug use is contributing to the increased spread of HIV among Iranian homeless. Harm reduction programs should be expanded, particularly among homeless injection drug users.

OBJECTIVETo determine the prevalence of HIV infection among homeless men and women and the related risk behaviors in Tehran, Iran.
METHODSIn 2007-2008, Tehran municipality stacked up 10672 homeless men and women for assessment of HIV and began collaboration with Iranian Research Center for HIV/AIDS (IRCHA) departments to conduct HIV infection prevalence surveys in homeless populations. The results were analyzed for associations with demographic information, family support, status of drug abuse and relation with family and friends.

Ebola virus is transmitted to people as a result of direct contact with body fluids containing virus of an infected patient. The incubation period usually lasts 5 to 7 d and approximately 95% of the patients appear signs within 21 d after exposure. Typical features include fever, profound weakness, diarrhea, abdominal pain, cramping, nausea and vomiting for 3-5 days and maybe persisting for up to a week. Laboratory complications including elevated aminotransferase levels, marked lymphocytopenia, and thrombocytopenia may have occurred. Hemorrhagic fever occurs in less than half of patients and it takes place most commonly in the gastrointestinal tract. The symptoms progress over the time and patients suffer from dehydration, stupor, confusion, hypotension, multi-organ failure, leading to fulminant shock and eventually death. The most general assays used for antibody detection are direct IgG and IgM ELISAs and IgM capture ELISA. An IgM or rising IgG titer (four-fold) contributes to strong presumptive diagnosis. Currently neither a licensed vaccine nor an approved treatment is available for human use. Passive transfer of serum collected from survivors of Junin virus or Lassa virus, equine IgG product from horses hypervaccinated with Ebola virus, a "cocktail" of humanized-mouse antibodies (ZMapp), recombinant inhibitor of factor VIIa/tissue factor, activated protein C, RNA-polymerase inhibitors and small interfering RNA nano particles are among the therapies in development. Preclinical evaluation is also underway for various vaccine candidates. One is a chimpanzee adenovirus vector vaccine; other vaccines involve replication-defective adenovirus serotype 5 and recombinant vesicular stomatitis virus.

Zika virus (ZIKV) has two lineages: African and Asian. Mosquito-borne flaviviruses are thought to replicate initially in dendritic cells and then spread to lymph nodes and the blood stream. Risk for infection through blood transfusion, sexual practices and perinatal transmission exists. The possible routes of perinatal transmission are during delivery, breastfeeding and by close contact between the mother and her newborn. Also, mucocutaneous exposures to the virus by infected blood or monkey bite, organ transplantation or hemodialysis are the other routes of ZIKV transmission. There are two types of ZIKV infection; Zika fever and congenital infection. Clinical presentation of Zika fever varies from asymptomatic infections to a self-limiting febrile disease with low grade fever, conjunctivitis, maculopapular rash, headache, retro-orbital pain and arthritis/arthralgia with periarticular edema, myalgia, vertigo, vomiting and asthenia. This clinical feature could be mistaken for dengue or chikungunya fevers. Microcephaly is the most important and frequently reported clinical picture of suspected congenital Zika syndrome. Laboratory tests are needed for diagnosis of ZIKV infection, because there is no known pathognomonic clinical, biochemical or radiological features. RT-PCR is the most well-liked assay. Serum samples are tested by immunoglobulin G ELISA with ZIKV antigen. Samples are also tested by immunoglobulin M ELISA. There is no certified vaccine or therapeutic medication. In asymptomatic or uncomplicated patients, treatment is not necessary.

Objective: Depression affects people living with HIV (PLWH) compliance leading to poor control infection. Previous observational studies showed an anti-depression effect of green tea extract (GTE). The therapeutic effect of GTE on depression were investigated in PLWH receiving antiretroviral therapy (ART). Methods: Fifty PLWH on ART with diagnose of mild to moderate of depression, participated in a double-blind, placebo-controlled trial and underwent 12 weeks of treatment with either 400 mg GTE capsules or placebo twice daily. The Hamilton depression scale of patients was measured before, 6 weeks and 12 weeks after treatment in two groups. The primary outcome measure was performed to evaluate the efficacy of GTE in improving depressive symptoms. Results: The mean of Hamilton score showed a significant difference between the two groups after 12 weeks (P = 0.035). Repeated measures ANOVA test showed a significant effect for time × treatment interaction on the Hamilton mean score between the two groups (P = 0.000). Conclusion: It seems the use of GTE capsules in PLWH on ART is safe and could lead to greater and more rapid improvement in depressive symptoms than placebo. Thus it can be considered as an alternative therapy for mild to moderate depression. Further studies with higher sample size and longer follow-up and comparisons with other antidepressive drugs are warranted.
