Fluorescence-Based Binding Characterization of Small Molecule Ligands Targeting CUG RNA Repeats.

Int J Mol Sci 2022 Mar 19;23(6). Epub 2022 Mar 19.

Department of Chemistry and The RNA Institute, University at Albany, State University of New York, 1400 Washington Avenue, Albany, NY 12222, USA.

Pathogenic CUG and CCUG RNA repeats have been associated with myotonic dystrophy type 1 and 2 (DM1 and DM2), respectively. Identifying small molecules that can bind these RNA repeats is of great significance to develop potential therapeutics to treat these neurodegenerative diseases. Some studies have shown that aminoglycosides and their derivatives could work as potential lead compounds targeting these RNA repeats. Read More

Human immunodeficiency virus-associated vacuolar encephalomyelopathy with granulomatous-lymphocytic interstitial lung disease improved after antiretroviral therapy: a case report.

AIDS Res Ther 2020 07 9;17(1):38. Epub 2020 Jul 9.

Department of Respiratory Medicine, Nagasaki University Hospital, Sakamoto 1-7-1, Nagasaki City, Nagasaki, 852-8501, Japan.

Background: Vacuolar encephalomyelopathy, a disregarded diagnosis lately, was a major neurological disease in the terminal stages of human immunodeficiency virus (HIV)-1 infection in the pre-antiretroviral therapy (ART) era. Granulomatous-lymphocytic interstitial lung disease (GLILD) was classically identified as a non-infectious complication of common variable immunodeficiency; however, it is now being recognized in other immunodeficiency disorders. Here, we report the first case of GLILD accompanied by vacuolar encephalomyelopathy in a newly diagnosed HIV-infected man. Read More

A Simple Symptom Score for Acute Human Immunodeficiency Virus Infection in a San Diego Community-Based Screening Program.

Clin Infect Dis 2018 06;67(1):105-111

Division of Infectious Diseases, Department of Medicine, University of California, San Diego.

Background: Treatment of acute human immunodeficiency virus (HIV) infection (AHI) decreases transmission and preserves immune function, but AHI diagnosis remains resource intensive. Risk-based scores predictive for AHI have been described for high-risk groups; however, symptom-based scores could be more generalizable across populations.

Methods: Adults who tested either positive for AHI (antibody-negative, HIV nucleic acid test [NAT] positive) or HIV NAT negative with the community-based San Diego Early Test HIV screening program were retrospectively randomized 2:1 into a derivation and validation set. Read More

Rhabdomyolysis as presenting feature of acute HIV-1 seroconversion in a pediatric patient.

Am J Emerg Med 2016 Apr 29;34(4):760.e3-5. Epub 2015 Aug 29.

Mercer University School of Medicine, Macon, GA.

Acute rhabdomyolysis is a rare phenomenon in the emergency setting almost exclusively associated with trauma, drugs, and recent upper respiratory and gastrointestinal infection. Rare reports in the literature have highlighted adult patients presenting with rhabdomyolysis as 1 component in a constellation of symptoms in acute HIV-1 seroconversion; however, there are few reports of rhabdomyolysis as the sole presenting symptom. This case highlights the importance of investigating HIV and other sexually transmitted diseases in pediatric cases of rhabdomyolysis in the emergency care setting. Read More

Skeletal muscle toxicity in HIV-1-infected patients treated with a raltegravir-containing antiretroviral therapy: a cohort study.

AIDS Res Hum Retroviruses 2014 Dec;30(12):1162-9

Department of Medical and Surgical Sciences, Infectious Diseases Unit, S. Orsola-Malpighi Hospital, Alma Mater Studiorum University of Bologna , Bologna, Italy .

To evaluate the frequency of myopathy and serum creatine kinase (CK) elevation associated with the use of the integrase inhibitor raltegravir we conducted a retrospective, cohort analysis assessing the incidence of skeletal muscle toxicity among HIV-infected patients treated with raltegravir. Adult HIV-infected patients who started a raltegravir-containing therapy were enrolled into the study. The skeletal muscle toxicity was defined by the presence of one or more of the following parameters: (1) isolated and significant CK elevation without signs or symptoms; (2) diffuse myalgia without weakness; (3) proximal muscle weakness; (4) rhabdomyolysis.

Chronic alcohol ingestion exacerbates skeletal muscle myopathy in HIV-1 transgenic rats.

AIDS Res Ther 2011 Aug 16;8:30. Epub 2011 Aug 16.

Department of Medicine, Emory University School of Medicine, 615 Michael Street, Atlanta, GA 30322, USA.

Background: Separately, chronic alcohol ingestion and HIV-1 infection are associated with severe skeletal muscle derangements, including atrophy and wasting, weakness, and fatigue. One prospective cohort study reported that 41% of HIV-infected patients met the criteria for alcoholism, however; few reports exist on the co-morbid effects of these two disease processes on skeletal muscle homeostasis. Thus, we analyzed the atrophic effects of chronic alcohol ingestion in HIV-1 transgenic rats and identified alterations to several catabolic and anabolic factors. Read More

Skeletal and cardiac myopathy in HIV-1 transgenic rats.

Am J Physiol Endocrinol Metab 2008 Oct 19;295(4):E964-73. Epub 2008 Aug 19.

Department of Cellular and Molecular Physiology, The Pennsylvania State University College of Medicine, Hershey, Pennsylvania 17033, USA.

The mechanism by which human immunodeficiency virus (HIV)-1 infection in humans leads to the erosion of lean body mass is poorly defined. Therefore, the purpose of the present study was to determine whether transgenic (Tg) rats that constitutively overexpress HIV-1 viral proteins exhibit muscle wasting and to elucidate putative mechanisms. Over 7 mo, Tg rats gained less body weight than pair-fed controls exclusively as a result of a proportional reduction in lean, not fat, mass. Read More

Effect of HIV-1-related protein expression on cardiac and skeletal muscles from transgenic rats.

AIDS Res Ther 2008 Apr 25;5. Epub 2008 Apr 25.

Pulmonary, Allergy and Critical Care Medicine, Atlanta VA Medical Center and Emory University School of Medicine, 1670 Clairmont Road, Decatur, GA 30033, USA.

Background: Human immunodeficiency virus type 1 (HIV-1) infection and the consequent acquired immunodeficiency syndrome (AIDS) has protean manifestations, including muscle wasting and cardiomyopathy, which contribute to its high morbidity. The pathogenesis of these myopathies remains partially understood, and may include nutritional deficiencies, biochemical abnormalities, inflammation, and other mechanisms due to viral infection and replication. Growing evidence has suggested that HIV-1-related proteins expressed by the host in response to viral infection, including Tat and gp120, may also be involved in the pathophysiology of AIDS, particularly in cells or tissues that are not directly infected with HIV-1.

Expert Opin Ther Targets 2007 Jun;11(6):835-51

Istituto Pasteur-Fondazione Cenci Bolognetti, Dipartimento di Studi Farmaceutici, Università di Roma La Sapienza, Piazzale Aldo Moro 5, I-00185 Roma, Italy.

In contrast to genetic aberrations, epigenetic aberrations can be reversed by the use of histone acetyltransferase (HAT), histone deacetylase (HDAC), SIRT, or histone methyltransferase (HMT) inhibitors. A well-known HDACi, suberoylanilide hydroxamic acid, has been recently approved for the treatment of cutaneous T cell lymphoma, and a number of HDACi are in clinical trials as anticancer drugs. In addition, HDACi could be useful in antimalarial and antifungal therapies and can reactivate the HIV-1 expression in latent cellular reservoirs, thus suggesting the use in a combination therapy with highly active antiretroviral therapy.

Serum creatine phosphokinase monitoring in patients infected with HIV.

Int J STD AIDS 2006 Jan;17(1):61-2

Worcestershire HIV Clinic, Worcestershire Acute Hospitals NHS Trust, Worcestershire Royal Hospital, Charles Hastings Way, Worcester WR5 1DD, UK.

Creatine phosphokinase (CPK) estimations are done routinely in some HIV clinics, irrespective of patient symptoms. We studied patients attending the Worcestershire HIV clinic between 1987 and 2001 to identify whether routine elevations in serum levels of CPK in patients with HIV were associated with clinical features of muscle disease (CFMD), and whether such elevations influenced patient management. There was no association between CFMD and a rise in CPK. Read More

Bovine immunodeficiency virus in experimentally infected rabbit: tropism for lymphoid and nonlymphoid tissues.

Comp Immunol Microbiol Infect Dis 2001 Jan;24(1):1-20

Laboratorio Virus Animales, Centro de Microbiología v Biologia Celular, Instituto Venezolano de Investigaciones Científicas, Caracas, Venezuela.

The bovine immunodeficiency virus (BIV)/New Zealand (Oryctolagus cuniculus) rabbit model was used to study events that underlie the early and chronic stages of viral replication, routes and time course of viral dissemination and the distribution of the virus in the lymphoid. nonlymphoid and mucosa associated tissues. The results indicated that BIV, a lentivirus with genetic relatedness to the HIV, induced changes of clinical (anorexia, weight loss, muscular wasting, diarrhea, hypoalgesia, torticollis), immunological (recurrent T- and B-cell dysfunctions) and histopathological (lymphadenopathy, splenomegaly) nature that closely parallels those described for cat (Fly), monkey (SIV) and human (HIV) lentiviral diseases.
