BACKGROUND Antisynthetase syndrome is a rare and debilitating multiorgan disease characterized by inflammatory myopathy, interstitial lung disease, cutaneous involvement, and frequent chronic inflammation of the joints. Standard treatments include corticosteroids and immunosuppressants. In some cases, treatment resistance may develop. Administration of immunoglobulins intravenously is recommend...

Primary immunodeficiencies (PIDs) are genetic disorders that predispose to frequent and severe infections, autoimmunity and cancer. The expanded life span of such patients increases the overall risk for developing cancer, which is now estimated at 4-25% . The type of malignancy depends on the primary immunodeficiency, the age of the patient and possible viral infection, suggesting that differen...

LP-BM5 retrovirus complex-infected C57BL/6 mice develop immunodeficiency, somewhat analogous to AIDS, termed murine AIDS (MAIDS). After secondary stimulation with syngeneic B-cell lymphomas from LP-BM5-infected mice, C57BL/6 mice produced vigorous CD8+ cytotoxic T lymphocytes specific for MAIDS-associated tumors. An anti-LP-BM5 specificity was suggested because spleen and lymph node cells from ...

It remains difficult to obtain high-resolution atomic force microscopy images of HIV-1 integrase bound to DNA in a dimeric or tetrameric fashion. We therefore constructed specific target DNAs to assess HIV-1 integrase binding and purified the complex by dialysis prior to analysis. Our resulting atomic force microscopy analyses indicated precise size of binding human immunodeficiency virus type ...

epidemiological studies have shown wide geographical and racial variation in the prevalence and patterns of immunodeficiency disorders. to determine the frequency of primary immunodeficiencies (pid) in iran, the iranian primary immunodeficiencies registry (ipidr) was organized in 1999. the diagnosis of immunodeficiency in our patients was based on standard criteria. the patient’s data were extr...

Major histocompatibility complex (MHC) class II deficiency is a primary immunodeficiency disease characterized by abnormality of MHC class II molecules surface expression on peripheral blood lymphocytes and monocytes. Clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections but the immunodeficiency is not as severe as SCID (severe combined immunodeficien...

Objective: Primary immunodeficiency diseases (PID) are rare and heterogeneous congenital diseases leading to increased unusual susceptibility to developing infections and causingsome malignancies and autoimmune diseases. This study was conducted to evaluate the epidemiological characteristics of primary these diseases in patients attending the clinic of immunodeficiency diseases in Kerman.Subje...

A statistically significant correlation exists between the locations of drug resistance mutations (DRMs) observed for various reverse transcriptase inhibitors and features of the secondary structure predicted for the RNA coding for human immunodeficiency virus type 1 reverse transcriptase. The known DRMs map onto "unstable" bases, which are predominantly nonhelical regions (i.e., loops, bulges,...

Background: Injecting drug users (IDUs) and prisoners are considered to be highly vulnerable to human immunodeficiency virus (HIV) infection in Iran. This study was carried out to determine the prevalence of HIV infection among IDUs released from jail in Bahar (Hamadan, Iran). Methods: In a cross-sectional study, 118 IDUs who were prisoners during 2001-07 were evaluated. Their demographic and p...
