Tuberculosis is the prototype of infections that require a cellular immune response for their control. It has been shown that CD4+ T-lymphocytes are most important in the protective response against Mycobacterium tuberculosis. CD8+ T-lymphocytes are also important for effective T-cell immune response. This study compares CD4+ and CD8+ baseline values in… (More)
Staphylococcus aureus is a significant cause of hospital-acquired pneumonia (HAP), particularly in mechanically ventilated patients. We used the fibronectin-binding protein A gene (fnbA) for the species-specific and quantitative detection of S. aureus directly from lower respiratory tract (LRT) specimens by a Taq Man real time PCR. For this reason, a total… (More)
Invasive fungal infections remain major causes of infection-related mortality in hematopoietic stem cell transplantation (HSCT) patients. Mixed infections and multiple organ involvement have been reported in these patients. Here, we report a case of mixed Aspergillus and Mucorales infection involving the lungs, brain, spleen and bone in a HSCT patient with… (More)
BACKGROUND Healthcare-associated outbreaks of fungal infections, especially with uncommon and emerging fungi, have become more frequent in the past decade. MATERIALS AND METHOD Here, we reviewed the history and definition of healthcare-associated outbreaks of uncommon fungal infections and discussed the principles of investigating, containing and… (More)
In 2001, a Liver Transplantation (LT) program was commenced in Imam Khomeini Hospital Complex as the first one in the capital city of Tehran which is the second liver transplantation center in Iran. This study presents the results of our 10-year experience with LT.
Brucellosis is a worldwide zoonosis. Infection with Brucella species results in the activation of cell-mediated immune response. The interaction between Th1and Th2 cytokines determines the outcome of disease. Production of each cytokine is in turn affected by genetic factors. In this study, we investigated the possible association between Th1 cytokines gene… (More)
BACKGROUND Pulmonary tuberculosis is still the most common form of tuberculosis in HIV infected patients having different presentations according to the degree of immunosuppression. This study appraised the impact of HIV infection on clinical, laboratory and radiological presentations of tuberculosis. METHODS The clinical, laboratory and radiological… (More)
Hepatitis A is acute and usually self-limiting disease, but sometimes it can be dangerous such as in immunosuppressed patients. Purpose of this study is to investigate the prevalence of hepatitis A serology in HIV/AIDS Patients. 247 HIV positive patients from March 2005 to September 2006 were entered in this study. Participants completed questionnaires to… (More)
Hepatitis A virus uncommonly causes neurological problems. Among these manifestations meningoencephalitis is very rare. We describe the clinical and laboratory features of a young boy with hepatitis A associated meningoencephalitis and compare it with other cases which had the same diagnoses.
OBJECTIVES The first liver transplant program in Tehran was started at Tehran University of Medical Sciences in 2002. The purpose of this study was to evaluate patient outcomes in this program. MATERIALS AND METHODS From January 2002 to February 2013, there were 172 deceased-donor orthotopic liver transplants performed in 166 patients, including revision… (More)
