  • Cryptosporidium parvum causes a life-threatening diarrhea in acquired immunodeficiency syndrome (AIDS) patients. THe sporozoite stage of C. parvum has been known to be a target in treating cryptosporidiosis in AIDS patients as it is an extracellular stage. A sporozoite was ultrastructurally observed. It has a creascent shape with a rounded posterior end and a tapering body. The compact nucleus was located at the posterior end. A monoclonal antibody was produced, which recognized a 43 kDa of sporozoite antigens in a western blot analysis and showed the surface labeling in immunofluorescence.

  • According to the advance of antiretroviral regimen and the early treatment strategy, people living with human immunodeficiency virus (PLWH) are achieving the goal of virologic suppression and immune restoration. Most of them no more die of acquired immunodeficiency syndrome (AIDS) defining illnesses, and become older with chronic comorbidities such as cardiovascular, metabolic, hepatic, renal and neurological diseases. However some PLWH still visit hospitals as late presenters with very low CD4+ T cell counts, so that they suffer AIDS defining illnesses to die or experience severe neurological complications resulting in disabilities. Early palliative interventions are needed on the various symptoms of PLWH. Thus far chronic pains such as distal symmetric sensory polyneuropathies have been underevaluated. Active pain-relieving interventions are important to them. Recently we define end of life condition of human immunodeficiency virus (HIV) or eligibility to hospice care after adjusting current status of HIV treatment. Hospice teams should pay attention to the specific medical conditions, psychological needs, and social circumstances of PLWH. With just standard precautions as common infection control measures, general hospice cares can be provided to them like to other hospices subjects. For giving PLWH opportunities to have the end of life with value and dignity, hospice multidisciplinary team should intervene them early and aggressively. Now we need more clinical experiences and institutional improvements.

  • 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.

  • Cytomegaloviruses (CMVs) are ubiquitous but highly species-specific agents which commonly infect many animals, including humans. Cytomegalovirus (CMV) pneumonia has been one of the most important opportunistic infections in the immunocompromised host for those who have acquired immunodeficiency syndrome (AIDS) or who have received kidney, bone marrow or other organs. Cytomegalovirus infection has been known to be associated with congenital, infantile and adult nephrotic syndrome. We report a rare case of CMV pneumonia with nephrotic syndrome in a 62-year-old female who recovered fully with ganciclovir.

  • The purpose of this paper is to review the literature of AIDS/HIV (acquired immune deficiency syndrome/human immunodeficiency virus) and to introduce physical therapy of the AIDS client. It was first reported that five young homosexual men, in 1981 in Los Angeles, died of pneumonia caused by pneumocystis carinii - called "pest of twentieth century". AIDS was implied a fatal breakdown of the functioning of the normal human immune system. The major routes of transmission has occurred via l)sexual contact between men, 2)heterosexual intercourse, 3)contaminated blood and blood products, and 4)intrauterine or pre-natal infection from mothers. AIDS clients who may require physical therapy for a wide range of problems due to respiratory, neurological, musculoskeletal and painful syndromes as well as general decline in fitness and function. AIDS is growing rapidly in our contury as well as all over the world. Therefore, physical therapist has to correct his understandings of AIDS in order to protect himself and to give proper physical therapy to the AIDS clients.

  • Background: Feline immunodeficiency virus (FIV) causes an acquired immunodeficiency-like syndrome in cats. FIV is latent. No effective treatment has been developed for treatment the infected cats. The first and second generations non-nucleoside reverse transcriptase inhibitors (NNRTIs) for HIV treatment, nevirapine (NVP) and efavirenz (EFV), and rilpivirine (RPV), were used to investigate the potential of NNRTIs for treatment of FIV infection. Objective: This study aims to use experimental and in silico approaches to investigate the potential of NNRTIs, NVP, EFV, and RPV, for inhibition of FIV reverse transcriptase (FIV-RT). Methods: The FIV-RT and human immunodeficiency virus reverse transcriptase (HIV-RT) were expressed and purified using chromatography approaches. The purified proteins were used to determine the IC50 values with NVP, EFV, and RPV. Surface plasmon resonance (SPR) analysis was used to calculate the binding affinities of NNRTIs to HIV-RT and FIV-RT. The molecular docking and molecular dynamic simulations were used to demonstrate the mechanism of FIV-RT and HIV-RT with first and second generation NNRTI complexes. Results: The IC50 values of NNRTIs NVP, EFV, and RPV against FIV-RT were in comparable ranges to HIV-RT. The SPR analysis showed that NVP, EFV, and RPV could bind to both enzymes. Computational calculation also supports that these NNRTIs can bind with both FIV-RT and HIV-RT. Conclusions: Our results suggest the first and second generation NNRTIs (NVP, EFV, and RPV) could inhibit both FIV-RT and HIV-RT.

  • Infection with HIV (Human immunodeficiency virus), over time, develops into acquired immunodeficiency syndrome (AIDS). The development of non-toxic and effective anti-HIV drugs is one of the most promising strategies for the treatment of AIDS. In this study, we investigated the anti-HIV-1 activity of gelatin hydrolysates from Alaska pollack skin. Gelatin hydrolysates were prepared using four enzymes (alcalase, flavourzyme, neutrase, and pronase E). Among these, the pronase E gelatin hydrolysate was found to inhibit HIV-1 infection in the human T cell-line MT4. It exhibited inhibitory activity on HIV-1IIIB-induced cell lysis, reverse transcriptase activity, and viral p24 production at noncytotoxic concentrations. Moreover, it decreased the activation of matrix metalloproteinase-2 (MMP-2) in vitro. Because HIV infection-induced activation of MMP-2 can accelerate collagen resolution and collapse of the immune system, pronase E gelatin hydrolysate might prevent the activation of MMP-2 in cells, resulting in collagen stabilization and immune cell homeostasis consistent with anti-HIV activation. These results suggest that pronase E gelatin hydrolysate could potentially be incorporated into a novel therapeutic agent for HIV/AIDS patients.

  • Purpose - This paper investigates whether one's occupation influences one's attitude toward people with HIV/AIDS and suggests ways to counter HIV-related stigma in different work settings. Two samples comprising workers in different environments and occupations with contrasting personalities were chosen. Thus, security guards (authoritarian types) and catering workers (social types) were included. Research design, data, and methodology - The sample comprised246 service staff from the Rhodes University Catering Division and the Hi-Tec Security company, both in Grahamstown, South Africa, a small Eastern Cape province town. All employees at these organizations during the survey were eligible to participate. Results -The security sample displays significantly higher personal stigma scores than the catering sample, according to the Visser personal stigma scale (mean scores of 4.01 and 1.37, respectively; t=10.30, df=244, p=0.00). Similar results were found using Visser subscales. Conclusions - This study shows that occupation is a strong predictor of HIV-related stigma in the workplace, suggesting that workplace settings, by attracting particular personalities and influencing workers, may shape attitudes towards those who are HIV positive.
