We report two infants with the acquired immunodeficiency syndrome (AIDS) and rectal bleeding due to cytomegalovirus (CMV) ileitis and colitis with minimal focal mucosal ulceration but with extensive leiomyolysis of the muscularis propria. Immunostaining and in situ hybridization for CMV showed numerous viral inclusions in the myocytes of the muscularis propria and vascular endothelium/smooth muscle with only occasional inclusions present in the muscularis mucosae. Colectomy was curative in one patient; in the other the bowel was only examined at postmortem.

We report the case of a 52-year-old male heterosexual patient with acquired immunodeficiency syndrome (AIDS) and reactivation of Chagas' disease manifested by meningoencephalitis and myocarditis, diagnosed post-mortem. Unexplained reactivation of Chagas' disease should be included among the diagnostic criteria of AIDS in human immunodeficiency virus positive patients. On the other hand, AIDS should be considered in the differential diagnosis of patients with unexplained reactivation of Chagas' disease.

Immunodeficiency Syndrome

Pathological abnormalities of the thymus were found in 3 of 37 fetuses aborted from human immunodeficiency virus (HIV)-infected mothers. These lesions were located predominantly in the thymic cortex, which contains mostly immature lymphocytes. Areas of focal lymphocyte depletion were infiltrated with CD4+ macrophages and were associated with abnormalities of the epithelial stromal network. No evidence of extensive HIV infection in any of the 37 thymuses was detected by either immunofluorescence or in situ hybridization techniques, although rare cells that expressed HIV antigens were found in 3 fetuses. Although less extensive, this thymic fetopathy was similar to that described in postnatal acquired immunodeficiency syndrome thymuses, strongly suggesting that the lesions were related to HIV infection. Thymic fetopathy might represent the initial injury to the lymphoid system in HIV-infected infants in whom early and severe immunosuppression develops.

AIDS (Acquired Immunodeficiency Syndrome) adalah syndrom yang timbul akibat adanya virus HIV (Human Immunodeficiency Virus) yang menyerang sistem kekebalan tubuh manusia. HIV/AIDS dapat menular melalui darah, sperma, cairan vagina, dan ASI (Air Susu Ibu). Penelitian ini dilakukan di Akademi Kebidanan Sandi Karsa Makassar yang terletak di jalan Bung lorong 2, Kelurahan Tamalanrea, Kecamatan Tamalanrea Jaya, Makassar. Jenis penelitian yang digunakan dalam penelitian ini bersifat deskriptif. Besarnya sampel yang digunakan adalah 30 responden dari 600 populasi yang dipilih secara Total Sampling. Di mana dalam pengambilan data digunakan instrumen berupa kuesioner yang dibagikan kepada responden. Dari keseluruhan responden didapatkan tingkat pengetahuan mahasiswa Akademi Kebidanan Sandi Karsa Makassar yang diteliti didapat 15 mahasiswa (50%) yang tingkat pengetahuan baik tentang HIV/AIDS dan terdapat 14 mahasiswa (46,7%) yang tingkat pengetahuan cukup tentang HIV/AID dan terdapat 1 mahasiswa (3,3%) yang tingkat pengetahuan kurang tentang HIV/AIDS

Plasmablastic lymphoma (PBL) is a subtype of non-Hodgkin’s lymphoma that manifests in patients with the diagnosis of human immunodeficiency virus (HIV), more prominently in the head, neck, and oral mucosal region. The diagnosis of this rare lymphoma serves as a concomitant diagnosis of acquired immunodeficiency syndrome. The case is of a 33-year-old previously healthy male, with an unknown diagnosis of HIV with a painful right mandibular mass. He was subsequently diagnosed with PBL and HIV. This case of PBL illustrates the importance of linking a rare and potentially life-threatening diagnosis as a possible first manifestation of HIV.

The early diagnosis of infection with the human immunodeficiency virus (HIV) in infancy is clinically important but remains problematic in the asymptomatic child born to an HIV-infected mother. In addition, many such women are unaware of their HIV infection until their child manifests symptomatic HIV disease. Nonspecific signs of pediatric HIV infection, such as generalized lymphadenopathy, hepatosplenomegaly, or persistent thrush, may be important in alerting the clinician to consider the possibility of HIV infection in the child whose history of HIV risk is unknown. We report one such sign which may be evident on plain chest radiography. The pathology of the thymus gland in pediatric acquired immunodeficiency syndrome has been described by Joshi and colleagues,1-3 who have reported precocious involution with marked reduction in thymus size and weight.

Abstract Context.—Progressive multifocal leukoencephalopathy is a fatal demyelinating disease of the central nervous system frequently seen in patients with impaired immune systems, particularly acquired immunodeficiency syndrome. JC virus (JCV), a human neurotropic polyomavirus, is the etiologic infectious agent of this disease. Objective.—The significantly higher incidence of progressive multifocal leukoencephalopathy in patients with acquired immunodeficiency syndrome than in patients with other immunosuppressive conditions suggests that molecular interactions between human immunodeficiency virus 1 and JCV, via the Tat protein, are responsible for the activation of the JCV enhancer/promoter and the development of progressive multifocal leukoencephalopathy. An indirect mechanism through activation of cytokines, such as transforming growth factor β1 and Smads 3 and 4, may also be responsible for the enhancement of JCV gene expression. Design.—Immunohistochemical analysis in progressive multifocal leukoencephalopathy samples and chloramphenicol acetyl transferase assays on cell cultures were performed to corroborate this hypothesis. Results.—The JCV capsid protein VP-1 was found in the nuclei of oligodendrocytes and in the nuclei and cytoplasm of bizarre astrocytes. Human immunodeficiency virus proteins, including p24 and Tat, were detected in the cytoplasm of astrocytes. Tat, but not p24, was detected in oligodendrocytes, suggesting that extracellular Tat accumulates in the nuclei of oligodendrocytes, where JCV gene transcription takes place. High levels of transforming growth factor β1 and Smads 3 and 4 were detected in JCV-infected oligodendrocytes. Results from in vitro studies confirm activation of the JCV early and late promoters by Smads 3 and 4. Conclusions.—These observations support our model, suggesting that the induction of transforming growth factor β1 by human immunodeficiency virus 1 Tat can stimulate its downstream factors, including Smads 3 and 4, which in turn augment transcription of the JCV promoter in glial cells.
