Drug Interactions With Antimalarial Medications In Older Travelers: A Clinical Guide, Jelena Lewis, Tania Gregorian, Ivan Portillo, Jeff Goad

Pharmacy Faculty Articles and Research

Increasingly older adults are traveling to international destinations with malaria as a present risk. Surveillance systems indicate that older adults are more likely to suffer severe complications from malaria. The role of health care providers in selecting an appropriate medication for chemoprophylaxis or treatment of malaria in adults becomes more difficult as older adults undergo physiologic changes that alter the pharmacokinetic and pharmacodynamic nature of medications potentially causing increased drug interactions, adverse events, and altered drug action. A comprehensive literature search from 1970 to present, with a focus on the last 10 years, was conducted on drug interactions, pharmacokinetic and …

Chronic Environmental Exposure To Metal Mixtures In Tribal Populations And Potential Immune System Effects, Jennifer J. Ong

Biomedical Sciences ETDs

Hardrock mining in the United States (US) has left a legacy of mixed metal mine waste sites. Wastes may contain multiple metals of health concern, including arsenic, cadmium, lead, mercury, and uranium, among others. Mining waste sites are disproportionately located on or contiguous to the watersheds of tribal lands. Due to proximity, and because of reliance on natural resources to maintain traditional diets and customs, Native American communities’ contact with multiple metals is often increased. Two impacted communities are the Cheyenne River Sioux Tribe (CRST) and Navajo Nation. Both tribes have expressed concerns that metals in mine waste adversely affect …

Viral Infections And Interferons In The Development Of Obesity, Yun Tian, Jordan Jennings, Yuanying Gong, Yongming Sang

Agricultural and Environmental Sciences Faculty Research

Obesity is now a prevalent disease worldwide and has a multi-factorial etiology. Several viruses or virus-like agents including members of adenoviridae, herpesviridae, slow virus (prion), and hepatitides, have been associated with obesity; meanwhile obese patients are shown to be more susceptible to viral infections such as during influenza and dengue epidemics. We examined the co-factorial role of viral infections, particularly of the persistent cases, in synergy with high-fat diet in induction of obesity. Antiviral interferons (IFNs), as key immune regulators against viral infections and in autoimmunity, emerge to be a pivotal player in the regulation of adipogenesis. In this review, …

Establishing Computational Approaches Towards Identifying Malarial Allosteric Modulators: A Case Study Of Plasmodium Falciparum Hsp70s, Arnold Amusengeri, Lindy Astl, Kevin Lobb, Gennady M. Verkhivker, Özlem Tastan Bishop

Mathematics, Physics, and Computer Science Faculty Articles and Research

Combating malaria is almost a never-ending battle, as Plasmodium parasites develop resistance to the drugs used against them, as observed recently in artemisinin-based combination therapies. The main concern now is if the resistant parasite strains spread from Southeast Asia to Africa, the continent hosting most malaria cases. To prevent catastrophic results, we need to find non-conventional approaches. Allosteric drug targeting sites and modulators might be a new hope for malarial treatments. Heat shock proteins (HSPs) are potential malarial drug targets and have complex allosteric control mechanisms. Yet, studies on designing allosteric modulators against them are limited. Here, we identified allosteric …

Developments For The Treatment Of Invasive Infections Due To Multidrug-Resistant Acinetobacter Baumannii, David Laurent, Richard Drew, Dustin Wilson

The University of Louisville Journal of Respiratory Infections

Acinetobacter baumannii is a significant pathogen in healthcare settings (specifically prominent in healthcare- and ventilator-associated pneumonia) due primarily to its virulence and resistance to a wide variety of antimicrobial drug classes, including carbapenems (CRAB). Existing therapies (notably polymyxins, minocycline, tigecycline, amikacin, and sulbactam) often result in suboptimal tissue concentrations, high rates of toxicity, and increasing rates of resistance. Although utilizing combinations of antibiotics (specifically those containing colistin) have been employed, results have been mixed, and control trials are lacking. Eravacycline is a novel tetracycline with an improved pharmacokinetic profile and more potent activity against A. baumannii relative to tigecycline. Cefiderocol …

Oral Fungal Microbiota: To Thrush And Beyond, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

The oral microbiota is complex, multikingdom, interactive, and involves extensive biofilm formation. While dominated by bacteria, Candida is a frequent member of this microbiota; however, several other potentially pathogenic fungi (among around 100 identified species) appear to reside in some individuals, including Cryptococcus, Aspergillus, and Fusarium. Oral candidiasis may manifest as a variety of disease entities in normal hosts and in the immunocompromised. These include pseudomembranous candidiasis (thrush), hyperplastic or atrophic (denture) candidiasis, linear gingival erythema, median rhomboid glossitis, and angular cheilitis. The purpose of this review is to describe the oral fungal microbiota (ie, oral mycobiota), …

Spontaneous Fungal Peritonitis: A Rare Complication Of Ascites Secondary To Right Heart Failure: A Case Report, Saaah Siddiqui Md, Dharti R. Patel Md, Arshad M. Iqbal Md, Ateeq Mubarik Md, Salman Muddassir Md, Fahad Zafar Md

Internal Medicine

•Spontaneous fungal peritonitis (SFP) is an infection defined as a neutrophil count (> 250 cells/mL) in the ascitic fluid with the evidence of positive fungal culture (1) while excluding other intra-abdominal infections. SFP is not as common as spontaneous bacterial peritonitis and has higher mortality rates due to late recognition and difficulty in differentiation between SFP and SBP. (1,2). The common risk factors that have shown to increase the mortality for SFP include hepatorenal syndrome, patient on SBP prophylaxis, elevated APACHE II scores on admission, and elevated lactate levels (2,3). Candida albicans and Candida glabrata are the two …

Antimicrobial Stewardship Programs, Kevin Stack, Eric Stack, Stelios Theophanous, Anne Gentry, Jason M. Pogue

Pharmacy and Wellness Review

Antimicrobial Stewardship Programs (ASPs) are becoming increasingly prevalent in the United States as concerns continue to mount regarding antimicrobial resistance and the lack of new, novel antibiotics being introduced. There are a multitude of factors that have contributed to the escalation in antimicrobial resistance, with some of the more common concerns being overly broad antimicrobial coverage and prolonged antimicrobial treatment amongst others. While antimicrobial resistance is a problem of international proportion, each health care institution remains responsible for assessing its own protocols pertinent to antimicrobial usage. ASPs have had unparalleled success in achieving their goals due to the collaboration of …

Antibiotic Stewardship And Overcoming Antibiotic Resistance In Upper Respiratory Tract Infections, Katherine Elsass, Austin Hilverding, Steve Blake, Brendan Rasor, Steven N. Leonard

Pharmacy and Wellness Review

Antibiotic resistance has rapidly become one of the most significant challenges facing modern health care. Despite widespread public education efforts by the national government and health organizations worldwide, there remains a significant lack of public understanding of antibiotic resistance, how to prevent it and the implications if the science and health care communities fail to find a solution. The Centers for Disease Control and Prevention (CDC) and the American College of Physicians (ACP) recently published updated guidelines for appropriate antibiotic use in upper respiratory tract infections. These guidelines include several key recommendations for acute bronchitis, pharyngitis and acute rhinosinusitis (including …

Legionnaires' Disease, A Rising Occurrence In The United States, Jennifer Harklerode, Olivia Henton, Myranda Smith, Rebecca Worden, Andrew Roecker

Pharmacy and Wellness Review

Legionella pneumophila, a microscopic bacterium usually responsible for a number of illnesses and fatalities, can eliminate a local population, a region or even a nation. In 1976, L. pneumophila was first discovered due to a number of cases presenting with pneumonia-like symptoms. These cases occurred in an isolated population attending an American Legion convention in Philadelphia, Pennsylvania, therefore lending to the name Legionella. Usually found in aquatic environments such as lakes, streams, cooling towers, air conditioning systems and hot tubs, its ability to thrive in artificial and natural environments makes it an ideal bacterium. L. pneumophila can be transmitted via …

Zika Virus Induced Neurological Disorders And Impacts On Public Health, Alexandra Herman, Martha Zimmerman, Olivia Vanscoy, Olivia Henton, Lindsey Peters

Pharmacy and Wellness Review

Zika virus is a public health emergency of international concern. Zika virus (ZIKV) is a mosquito-borne pathogen that is carried by the Aedes genus. Zika is spread through direct bite and nonvector transmission. Most individuals infected with Zika will be asymptomatic, but some may present nonspecific viral symptoms. A rising number of neurological disorders in newborns whose mothers were infected with ZIKV during pregnancy have been reported due to recent outbreaks. Neurological disorders affect both the central and peripheral nervous systems and can result from bacterial, viral, fungal or parasitic infections of the nervous system or from the immune response …

The Zika virus has become a growing concern as a global pandemic. Since being identified in Uganda in 1947, the virus has spread around the world, recently emerging in South America with a great impact on Brazil. As of 2016, Zika has made its appearance in the United States and is now actively being transmitted in Florida. The virus is a mosquito-vectored flavivirus primarily transmitted by the Aedes mosquito which infects a human through biting. Transmission through sexual intercourse is also possible as well as transmission from a pregnant woman to her fetus. This latter form of transmission presents the …

Combating Antibiotic Resistance In The 21st Century, Kevin Krivanek, Brian Heilbronner, Brendan Rasor, Kelsey Lindsley, Andrew Roecker

Pharmacy and Wellness Review

Antibiotic resistance is one of the most significant challenges facing the medical community today. In response, the Centers for Disease Control and Prevention (CDC) created a list of the greatest antibiotic resistance threats, a number of which are gram-positive bacteria. The cell wall of these organisms has long been a favored target of antibiotic therapies, but the development of numerous resistance mechanisms has led to widespread resistance against nearly all major antibiotic compounds on the market. The medical community is faced with the task of developing better antibiotic compounds that preclude the spread of bacterial resistance and also increasing the …

Whooping Cough: A Pharmacist's Role In An Emerging Endemic, Haley Armstrong, Lydia Suchecki, Sarah Lipperman, Taylor Roberson, Andrew M. Roecker

Pharmacy and Wellness Review

Pertussis is an acute infectious disease caused by the organism Bordetella pertussis and characterized by a "whooping cough." Incidence of the disease had declined since the development of a vaccine, but is now increasing in reported cases. This increase has been attributed to both an increased awareness but also surmised to be related to a decrease in vaccinations. The pertussis vaccine is given in conjunction with tetanus and diphtheria vaccines to children before the age of 6 in five separate injections over the course of four to six years. A booster is now recommended for the older child and adults …

A Comparison Of Mipomersen (Kynamro®) And Lomitapide (Juxtapid®): Medications For The Treatment Of Homozygous Familial Hypercholesterolemia, Ann Marie Ruhe, Austin Brown, Ginny Daniels, Kelsey Fink, David Bright

Pharmacy and Wellness Review

Homozygous familial hypercholesterolemia (HoFH) is a rare disease that involves mutations in the genes coding for low density lipoprotein (LDL) receptors, preventing the uptake of LDL cholesterol from the serum and resulting in extremely high cholesterol levels.1 Between December 2012, and January 2013, two orphan drugs were approved by the U.S. Food and Drug Administration (FDA) for the treatment of HoFH. Mipomersen (Kynamro®) is a subcutaneous injection that functions as an antisense oligonucleotide inhibitor and ultimately prevents the translation of mRNA coding for apolipoprotein B (apoB)-100 which binds to LDL and very low density lipoprotein (vLDL) cholesterol.7 Lomitapide (Juxtapid®) is …

Fda Approves New Tuberculosis Drug: Bedaquiline (Sirturo®), Megan Ruffner, Kent Wilin, Charles Hay, Zachary Crawford, Andrew Roecker

Pharmacy and Wellness Review

Tuberculosis (TB), caused by the acid-fast bacilli (AFB) Mycobacterium tuberculosis, is an infectious disease that continues to greatly impact morbidity and mortality worldwide; in 2011 it caused 1.4 million deaths. Some strains of the bacteria have become resistant to current treatment regimens, resulting in multidrug-resistant (MOR) and extensively drugresistant (XOR) TB. The emergence of these resistant strains of bacteria calls for new treatment regimens that can quickly and effectively eradicate the organism. The U.S. Food and Drug Administration (FDA) recently approved Sirturo® (bedaquiline) with the indication of MDR pulmonary TB. Bedaquiline introduces a novel mechanism of action via the inhibition …

Laboratory Mutations Of H5n1 Confer Efficient Transmission In Animal Models And Generate International Debate Regarding Publication Of Dual Use Research, Morgan A. Belling, Kelly Dye, Joshua Ilenin, Jamie Amero, Andrew M. Roecker

Pharmacy and Wellness Review

H5N1, a subtype of influenza A virus that originated in Hong Kong in 1997 and has since spread across Asia and Africa, features a reported case fatality rate of nearly 60 percent in humans. Although naturally-occurring H5N1 has not developed the ability to be efficiently transmitted from human to human, two independent research teams have recently mutated strains of the virus, resulting in facile transmission among laboratory ferrets, which are considered the most accurate models for humans in viral studies. As a consequence of the security and public health risks of such information, the U.S. National Science Advisory Board for …

Fidaxomicin (Dificid®): New Antibiotic Approved For The Treatment Of Clostridium Difficile Infections, Sara M. Mcallister, Zachary Crawford, Joshua Ilenin, Ellen Hazelet, Andrew M. Roecker

Pharmacy and Wellness Review

Clostridium difficile is a gram-positive, spore forming bacteria normally transmitted by the fecal-oral route. Infection develops in patients with decreased normal gut flora and is typically associated with recent antibiotic use. Other risk factors include bowel surgery, compromised immune system function, extended hospital stays, and other underlying diseases. C. difficile bacteria produce two toxins, which cause increased intestinal fluid secretion and inflammation. Patients commonly present with diarrhea, abdominal discomfort, loss of appetite, and nausea. Current treatment guidelines are to discontinue antimicrobial agents and increase hydration. Less severe C. difficile associated diarrhea (CDAD) cases are treated with metronidazole 500 mg three …

Ecthyma Gangrenosum In An Immunocompromised Patient Without Detectable Bacteremia, Jonathan Miles, Alex Mari, Matthew Crabtree, Vinod Nambudiri, Jilian Sansbury

Dermatology

Ecthyma gangrenosum (EG) is typically pathognomonic of Pseudomonas aeruginosa bacteremia among immunocompromised patients, particularly with underlying malignancy. Recently, other pathogens and clinical histories have been implicated, challenging the classic picture of patients with EG. The cutaneous findings in patients follow a pattern of lesion progression from indurated pustules and hemorrhagic vesicles evolving to necrotic ulcers with central black eschar and surrounding erythema. While lesions typically occur on the perineum or lower extremities, their presence has also been described elsewhere. Herein, we describe a case of an immunocompromised man with chronic lymphocytic leukemia and multiple myeloma actively undergoing chemotherapy presenting with …
