Haart Therapy

The prognosis of HIV infection has considerably improved following the introduction of highly active anti-retroviral therapy by reducing AIDS related morbidity and mortality. At the same time, ART drugs are well known for their side effects. Gynaecomastia is a lesser known side effect of a commonly used anti-retroviral drug efavirenz. There are very few reports of HAART-induced gynaecomastia in resource-limited settings. The current study presents a series of three cases that developed ultrasound confirmed gynaecomastia following efavirenz containing HAART. Initial reports of gynaecomastia related to HAART were in HIV patients with lipodystrophy, they were termed as pseudogynaecomastia. Gradually, few reports of efavirenz related gynaecomastia were published wherein other causes of gynaecomastia were ruled out. Several hypothesis have been suggested for the pathophysiology of development of gynaecomastia related to efavirenz consumption. All other causes were ruled out in our patients too. The incidence of gynaecomastia is increasing in men with HIV on HAART therapy, proper identification and management will promote better drug adherence.

Morphological Diagnostics

Background. The progression of HIV infection is accompanied by the development of opportunistic diseases, including pleural effusions of various origins. Morphological examination of pleura tissue in cases of pleural effusion serves as the basis for establishing the etiology of the pathological process and, therefore, the final clinical diagnosis. Objective – analysis of results of morphological diagnostics of pleura lesions in HIV-infected patients in comparison with other laboratory tests and clinical diagnosis. Methods. 103 cases of pleurisy of various origins were studied. Pleural biopsies were obtained by various types of minimally invasive diagnostic interventions with subsequent morphological examination. Results were compared with the available data of microbiological and molecular genetic studies of pleural biopsies. Results. At the time of hospitalization the preliminary clinical diagnosis was pleurisy of unknown etiology in 96,1 % of cases. A combined disease was diagnosed – hepatitis C in a third of all observations according to the results of laboratory tests. Due to routine staining with hematoxylin and eosin, tuberculosis lesions of the pleura were diagnosed in 59,2 %, the second most frequent was the diagnosis of nonspecific pleurisy, 20,4 %. According to the duration of the process, acute pleural tuberculosis was established in 19,7 % of cases, the subacute form of tuberculosis pleurisy – in 54,1 % of cases, and chronic pleural tuberculosis was established in 22,9 % of cases. In 17,5 % of cases, in order to clarify the etiology of pleurisy, additional histochemical staining for infectious agents was performed. The results of microbiological and molecular genetic studies were established in 76,7 % of cases. The greatest number of M. tuberculosis detection was obtained during the culture study of the biopsy material and exudates. When comparing the final clinical diagnosis and the level of CD4 cells in peripheral blood, it was found that in most cases (74,5 %) pleural effusions developed at low counts of CD4 cells, less than 350/l. Conclusion. Tuberculosis predominates in the etiological structure of pleural effusions in patients with HIV infection. Pleural tuberculosis can be the main secondary disease or be combined with pulmonary tuberculosis. In second place in terms of frequency of occurrence, nonspecific pleurisy was diagnosed as a complication of the main secondary disease. Pleural effusions develop when CD4 cell counts are low. Morphological diagnostics of pleural lesions is the main research method in the diagnostic algorithm of cases of pleural effusions of unknown etiology against the background of HIV infection.

Ige Synthesis

Increased levels of serum IgE and eosinophilia have been described in human immunodeficiency virus (HIV) infection, almost exclusively in patients with CD4+ cell count < 200 cells/microliters. IgE production is regulated by CD4+ T helper type 2 (Th-2) lymphocytes, producing interleukin 4 (IL-4) and expressing a ligand for the B cell-specific CD40 molecule (CD40 ligand [L]). A shift to a Th-2-like pattern of cytokine secretion has been postulated to be associated with progression toward acquired immunodeficiency syndrome (AIDS). We studied three AIDS patients with very high levels of IgE and almost complete depletion of CD4+ lymphocytes, suggesting that IgE synthesis could not be driven by CD4+ cells. IgE in vitro synthesis by cells from such patients was, however, inhibited by anti-IL-4. We show that both CD8+ T cell lines and the majority of CD8+ T cells clones derived from these patients produce IL-4, IL-5, and IL-6 in half of the cases together with interferon gamma (IFN-gamma). 44% of CD8+ T cell clones expressed a CD40L, and the supernatants of the clones were capable of inducing IgE synthesis by normal B cells costimulated with anti-CD40. CD8+ T cells in these patients therefore functionally mimic Th-2 type cells and may account for hyper-IgE and eosinophilia in the absence of CD4+ cells. The presence of such CD8+ cells may also provide a source of IL-4 directing the development of predominant Th-2 responses in HIV infection.

The Impact

Background of study: There is emerging evidence that human immunodeficiency virus (HIV) infection, even in the absence of anti-retroviral therapy (ART) toxicity and other cofactors, may have a direct impact on liver pathogenesis. Aim: Based on this premise, our study determined the impact of HIV infection on liver enzymes as markers of hepatic function. Methods: the case-control study comprised of a total of 60 participants (30 males and 30 females) aged 18-60 years. The study compared aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), cluster of differentiation (CD4+) cells among ART-naïve HIV patients (n=20), follow-up HIV patients who were on highly active ART (n=20) and apparently healthy controls (n=20). Results: a significant (P<0.05) change was observed in the liver enzymes and CD4+ cells among the study groups compared. Specific changes showed that serum AST, ALP levels of ART-naïve patients were significantly (P<0.05) higher than that of follow-up and controls. Serum ALT levels of controls were significantly (P<0.01) lower than that of ART-naïve and follow-up patients. The CD4+ cell count of ART-naïve patients was significantly (P=0.000) lower than that of follow-up and control groups. Conclusion: Liver enzyme abnormalities were observed in ART naïve HIV infected patients. Consequently, there is a need to monitor liver enzyme levels before and after initiation of therapy.

Haart Therapy

The prognosis of HIV infection has significantly changed following the introduction of highly active anti-retroviral therapy by reducing AIDS related morbidity and mortality. At the same time, HAART is documented for its side effects. Gynaecomastia is a less documented side effect of a commonly used ART drug efavirenz. There are only few case reports of HAART-induced gynaecomastia in resource limited settings. Initially gynaecomastia related to HAART in HIV patients was thought due to lipodystrophy and was termed as pseudogynaecomastia. Later, few case reports of efavirenz related gynaecomastia were published after ruling out other causes of gynaecomastia. All other causes of gynaecomastia were ruled out in our patients too. The incidence of gynaecomastia is increasing in men with HIV on HAART therapy, proper identification and management will promote better drug adherence. The present study presented a series of two cases that developed ultrasound confirmed gynaecomastia following efavirenz containing HAART.

Abstract: HIV viremia is the essential element for progression of an initial HIV infection into AIDS and death. The currently approved management relies primarily on chemotherapy repressing the HIV replication in the infected CD4+ cells, although with severe systemic adverse effects. The problem is that it does not physically eliminate viruses, which then not only keep infecting healthy cells of these patients, but also promote infectivions of other people.

In spite of significant advancements and success in antiretroviral therapies directed against HIV infection, there is no cure for HIV, which scan persist in a human body in its latent form and become reactivated under favorable conditions. Therefore, novel antiretroviral drugs with different modes of actions are still a major focus for researchers. In particular, novel lead structures are being sought from natural sources. So far, a number of compounds from marine organisms have been identified as promising therapeutics for HIV infection. Therefore, in this paper, we provide an overview of marine natural products that were first identified in the period between 2013 and 2018 that could be potentially used, or further optimized, as novel antiretroviral agents. This pipeline includes the systematization of antiretroviral activities for several categories of marine structures including chitosan and its derivatives, sulfated polysaccharides, lectins, bromotyrosine derivatives, peptides, alkaloids, diterpenes, phlorotannins, and xanthones as well as adjuvants to the HAART therapy such as fish oil. We critically discuss the structures and activities of the most promising new marine anti-HIV compounds.
