  • 본 연구는 인간면역결핍바이러스의 입자를 비이온성 계면활성제로 처리할 때 바이러스 입자구조에서 분리되어 방출되는 바이러스 구조단백질들의 분포를 sucrose gradient로 분석하여, 바이러스 입자를 구성하는 바이러스 구조단백질과 바이러스입자의 생물리학적 특성을 연구하였다. 바이러스입자들을 0.16% NP40 (Nonidet P-40)으로 처리할 때, 바이러스 capsid 단백질과 바이러스 막 단백질 (membrance protein)들은 다른 바이러스 구성성분들과 잘 분리되었다. 계면활성제처리에서 방출되지 않은 구성 성분들은 matrix 단백질, nucleocapsid 단백질, reverse transcriptase, integrase 및 바이러스 RNA genome로써, 이들은 subviral 구조를 형성한다. 이러한 결과는 상대적으로 다른 바이러스들의 capsid 단백질과 면역 결핍 바이러스의 capsid 단백질 (p24)를 비교할 때, 면역결핍바이러스의 capsid 단백질은 바이러스핵을 형성할 때, capsid 단백질 사이의 결합력이 매우 약한 것으로 추정된다. 또한 바이러스 조절단백질의 하나인 vpr 단백질을 함유하는 바이러스입자를 NP40 처리하여 분석하였을 때, vpr 단백질은 subviral 구조에 존재하는 것으로 나타났다.

  • AIDS, 즉 후천성면역결핍증은 인간면역결핍바이러스(Human Immunodeficiency Virus : HIV)라고 불리우는 바이러스에 의한 인간면역체계의 붕괴로 발생하는 질환이다. 1979년 최초로 새로운 임상적특징을 가진 증후군으로 의학학술지에 발표되어 의료계의 주목을 끌어오다가 1981년 봄 로스앤절레스에 있는 남성동성연애자에게 발생한 AIDS의 첫 예가 보고되어 본격적 연구가 시작되었다.

  • There is no known publication about assessment of quality of life (QOL) in Korean HIV patients. We aimed to assess the QOL of HIV patients. We developed Korean version of the WHOQOL-HIV BREF (short forms of WHOQOL-HIV, 31 questions with 6 domains). Survey data from 220 HIV-positive adults were obtained in 14 centers in South Korea. Male were dominant (202/220, 91.8%). Mean age was $40.6{\pm}12.1$. Mean CD4+ T-cell count was $414.9{\pm}226.6/ml$. Overall of WHOQOL-HIV BREF were $53.2{\pm}14.9$ (perfect score=100) (Cronbach's ${\alpha}$ = 0.942). It is similar score comparing to another country (Portugal: 54.75/100, measured by WHOQOL-HIV). Correlations of WHOQOL-HIV BREF score with patients' subjective QOL and with subjective satisfaction were 0.747 (p <0.01) and 0.651 (p <0.01), respectively. WHOQOL-HIV BREF have internal reliability. There is in need of monitoring for QOL of HIV patients in the clinical practice and trials. This survey tool could be used to assess the effect of intervention. Additionally, comparison across countries would be possible and promising.

  • A 54-year-old homosexual man was diagnosed as human immunodeficiency virus-1-positive in 1992. He was admitted to a tertiary hospital in March, 2000 because of right flank pain, fever and intermittent cough. A chest roentgenogram showed right-sided pleural effusion, and closed thoracostomy was performed for drainage Salmonella species and Escherichia coli were isolated from the pleural fluid. In spite of 6 weeks of antibiotic treatment, fever did not subside and the general condition gradually deteriorated, and under the diagnosis of lung abscess with empyema thoracis, right pleuropneumonectomy was performed. The general condition improved postoperatively until day 10 when he showed sudden change in mental status to stuporous and developed focal seizure. Brain CT showed multiple abscesses in right frontal and left frontotemporal lobes and he expired on postoperative day 14.

  • 인간면역결핍바이러스(Human Immunodeficiency Virus: 이하 HIV로 표기) 감염환자에서 발생하는 기회감염은 다양한 미생물에 의해 발생한다. 기생충이 일으키는 감염질환은 세균이나 곰팡이, 바이러스가 일으키는 감염질환에 비해 발생빈도가 낮아 중요성이 간과되는 경우가 흔하지만, HIV 감염환자에게는 여전히 중요한 감염질환이다.

  • There are two forms of cryptococcal meningitis immune reconstitution inflammatory syndrome (CM-IRIS): paradoxical CM-IRIS and unmasking CM-IRIS. It is important to distinguish paradoxical CM-IRIS and CM relapse because mortality of CM-IRIS is higher than that of CM without IRIS, and paradoxical CM-IRIS and CM relapse requires different treatment. We report a case of paradoxical CM-IRIS that well matches the clinical findings with MR findings during three years follow-up of a HIV infected patient and new MRI finding is also introduced to help distinguish them.

  • Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) cause viral infections that lead to chronic diseases. When they invade human body, virus specific T cells play an important role in antiviral effector functions including killing virus-infected cells and helping B cells to produce specific antibodies against viral proteins. The antiviral activity of T cells is usually affected by immune-regulatory factors that express on surface of T cells. Recently, many researchers have investigated the relationship between effector functions of virus specific T cells and characteristics of immune regulatory factors (e.g., CD28, CD25, CD45RO, FoxP3, PD-1, CTLA-4). In particular, Immune inhibitory molecules such as forkhead box P3 (FoxP3), programmed death-1 (PD-1), and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) are associated with T-cell dysfunction. They are shown to be up-regulated in chronic viral diseases such as hepatitis B, hepatitis C or human immunodeficiency virus infection. Therefore, the positive correlation between viral persistence and expression of immune regulatory factors (FoxP3, PD-1, and CTLA-4) has been suggested. In this review, the roles of immune regulatory factors FoxP3, PD-1, and CTLA-4 were discussed in chronic viral diseases such as HIV, HBV, or HCV.

  • We have previously demonstrated that intracellular expression of an RNA aptamer termed RRE40, which was selected in vitro to bind HIV Rev 10-fold much tighter than wild-type RRE, efficiently protected human CD4+ T cell line, CEM, from HIV-1. In this study, to evaluate the efficacy of the RRE40 RNA in clinical settings, polyclonal CD4+ peripheral blood lymphocytes (PBLs) were transduced with retroviral vectors expressing RRE40 decoy RNA and then challenged with clinical isolates of HIV-1. In contrast to the control cells transduced with vectors expressing control tRNA, intracellular expression of RRE40 RNA more effectively inhibited HIV-1 replication in CD4+ PBLs. However, transient and diminished inhibition, rather than complete inhibition, of HIV-1 replication in PBLs expressing RRE40 decoys have been observed. These results suggest that RRE40 decoy RNA would be useful to inhibit HIV-1 replication in cells. However, development of more efficient gene transfer protocols and/or more effective decoy RNAs would be needed to apply RNA decoy to modulate HIV-1 patient.

  • The purpose of this study was to develop an application(app) on smoking cessation for patients with human immunodeficiency virus (HIV) infection and evaluate its usability. A methodological study design was applied. The program contents were developed by expert panel based on the theory of planned behavior, HIV infection, and smoking cessation and usability evaluation and then the application was developed by IT experts following usability testing composed of heuristic evaluation by 3 mobile experts and users evaluation was conducted using surveys and interviews by 10 individuals with HIV infection. Descriptive statistics and contents analysis were computed to evaluated the collected data. All participants were male and their age were ranged from 40s to 60s. The average of app usability was 4.2. The participants experienced no difficulties and responded somewhat satisfaction. The results showed that the app was feasible and useful on smoking cessation for HIV patients and could be used as an valid approach.
