The Spirochetes: Leptospirosis and Relapsing Fever
Dr. Richard L. Oehler, Professor of Medicine at the Division of Infectious Diseases, Morsani College of Medicine, reviews two important clinical syndromes caused by Spirochetes. Dr Oehler begins by presenting an actual clinical case of Leptospirosis in a returning traveller from the Caribbean. He then discusses the epidemiology of Leptospira, a widespread zoonotic pathogen that favors temperate and topical climates worldwide. He then relates the life cycle, means of transmission, microbiology, clinical manifestations, and most relevant diagnostic studies. He concludes the leptospirosis section by discussing treatment and prevention. The second case he discusses is a febrile illness in a returning traveler from Jordan. Dr. Oehler goes on to discuss the epidemiology and classification system for relapsing fever (RF), and its broad categorization into tick-borne (endemic) and louse-borne (epidemic) forms. He further describes the characteristics of the soft-shelled Ornithodoros ticks and the Human Body Louse, and differentiates the Hard Tick Relapsing Fevers such as Borellia miyamotoi and B. lonestarii. He then reviews the clinical manifestations, diagnostic criteria, and treatment options for each form of RF. Lastly, Dr, Oehler breaks down treatment and prevention strategies for each form of relapsing fever.
Syphilis: An Epidemic
Dr. Kitan Amin, Infectious Diseases Fellow at the USF Morsani College of Medicine, presents this talk on the current state of syphilis in the U.S. Dr. Amin begins by discussing the epidemiology and classification of Treponemial organisms. The history of Syphilis is then reviewed, including the origins of the disease in the new world and the unfortunate history of the Tuskegee trials. Next, the clinical manifestations of Syphilis are detailed, including primary, secondary, late latent, and neurosyphilis. The unique effects of Syphilis in HIV are also covered. Lastly, syphilis testing and treatment are reviewed, including the effects of the recent Benzathine penicillin shortage and alternatives to Penicillin for treatment.
Pneumocystis Pneumonia in Cushings Disease
Dr Cilia Nazef, Infectious diseases Fellow at the University of South Florida Morsani College of Medicine, explores how Pneumocystis jirovecii, a fungal infection typically affecting immunocompromised patients, can also affect patients suffering from hypercortisolism. Dr. Nazef begins by examining different cases of Pneumocystis jirovecii Pneumonia (PJP) in patients with Cushings disease. Next, she further explains the immunologic basis behind how the hypercortisol state induces immunosuppression. Dr. Nazef closes by examining the basis for PJP prophylaxis in Cushings disease patients, and the shortcomings of the current literature in advocating prophylaxis options.
HIV in Older Patients
Dr. Todd Wills, Professor of Medicine with the Morsani College of Medicine at the University of South Florida, reviews the unique complications and issues that can occur in the elderly HIV patient. Dr. Wills begins by reviewing the epidemiology of HIV by age group, including the fact that the HIV positive population is growing older with time. Dr. Wills also discusses issues regarding polypharmacy and medication tolerability in the older patient. Next, the speaker relates how the high prevalence of chronic diseases affect the HIV positive patient’s prognosis. HIV positive elderly patients can suffer not just from frailty, but from cardiovascular disease, diabetes, osteoporosis, and cancer. Dementia can also affect an elderly HIV paitent’s overall wellness and compliance with antiviral therapy. Dr. Wills also covers the assessment of bone density in elderly HIV positive patients. Lastly, Dr. Wills discusses HIV positive patient life expectancy in the modern age of antiretroviral therapy. The lecture is updated for 2024.
Getting to the HAART of HIV Drug Interactions
Dr. Sung Soo Kim, ID clinical pharmacist, presents a talk on the spectrum of HIV therapy and ART (Antiretroviral Therapy)-related adverse drug interactions. Dr. Kim begins by describing the mechanisms by which HIV therapy-related adverse drug interactions occur. Next, he discusses the various classes of antiretrovirals and their specific drug interactions, including integrate inhibitors, NNRTIs, NRTIS, and Protease Inhibitors. Dr. Kim closes by discussing the consequences of unmanaged drug-drug interactions in patients on ARTs as well as the available drug-drug interaction resources available to the clinician.
ID Management of Hematologic Malignancies and Stem Cell Transplants
Dr. Olga Klinkova covers essential information regarding the management of infectious complications of hematologic malignancies. Topics covered include the initial evaluation of patients, neutropenic fever, neutropenic enterocolitis, and antimicrobial prophylaxis. Next, Dr. Baluch discusses ID management of stem cell transplants, CAR-T therapy, and when it is necessary to administer antimicrobial prophylaxis in these patients. The lecture is updated as of 2024.
What to Do With a Positive Blood Culture in 2024
Dr. Richard Oehler, Professor of Medicine at the Division of Infectious Diseases at the University of South Florida Morsani College of Medicine, presents a review of bacteremia. Dr. Oehler begins by reviewing the epidemiology, personal and institutional costs of bacteremia. He then discusses blood culture collection and how false positive blood cultures occur. With the recent blood culture bottle shortage of 2024, he emphasizes the new concept of “blood culture stewardship”–when it is most appropriate to order a blood culture versus when it may be unnecessary. Next, Dr. Oehler reviews automated blood culture systems and other related identification technology, with a focus on new methods of blood culture isolate identification such as multiplex PCR and Maldi-TOF. The speaker then contrasts gram positive and gram negative bacteremia in general and by organism. The management of a positive blood culture with regard to treatment and source control is discussed. Lastly, ways to reduce the incidence of bacteremia are shared.
HIV-Associated Opportunistic Infections
Dr. Jackie Sherbuk, Assistant Professor of Medicine at the USF Morsani College of Medicine, presents this case-based review of the opportunistic infectious syndromes associated with HIV-AIDS. The speaker covers PJP prophylaxis and treatment, HIV pulmonary disease, and cryptococcal meningitis. Dr. Sherbuk also discusses IRIS (Immune Response Inflammatory Syndrome) and its effect on the AIDS patient when antiretrovirals are started. Lastly, Dr. Sherbuk covers HIV esophageal disorders, Histoplasmosis, Coccidioidomycosis, and Mycobacterium avian-complex-related syndromes.
Antiretroviral Therapy In Clinical Practice: A Case-based Approach
Dr. Jackie Sherbuk, Assistant Professor of Medicine at the Morsani College of Medicine Division of Infectious Diseases, presents this case-based review of the use of antiretroviral therapy in HIV/AIDS patients. Dr. Sherbuk begins by reviewing and available antireturovial options, including those that are considered first line. She also covers the use of antiretrovirals in special groups, including expectant mothers, elite controllers, treatment experienced patients, HBV/HIV connected patients, and patients with chronic renal insufficiency. Lastly, Dr. Sherbuk discusses the nuances of using co-formulated combinations of antiretrovirals and mentions the newer long-acting injectable preparations.
