The epidemiology, mechanisms, diagnosis and treatment of cardiovascular disease in adult patients with HIV.

More than 1.2 million people in the United States have Human Immunodeficiency Virus (HIV) infections but 13% of these people are unaware of their HIV infection. Current combination antiretroviral therapy (ART) does not cure HIV infection but rather suppresses the infection with the virus persisting indefinitely in latent reservoirs in the body.

Uncommon presentations of common variable immunodeficiency.

Common variable immunodeficiency (CVID) is a primary immunodeficiency disorder that causes decreased immunity and increased susceptibility to infections. It affects B lymphocyte differentiation, resulting in predominantly bacterial and less frequently viral, fungal, and protozoal infections. The respiratory and gastrointestinal tracts where antibody defences are essential are usually affected.

Main Body: India has reported world's highest number of CAM cases where was the most predominant etiology. CAM caused by was the most common from the rest of the world.

Zoonotic Bacterial Respiratory Infections Associated With Cats and Dogs: A Case Series and Literature Review.

Cats and dogs make up an essential part of the household for families in the United States. Close contact with pets can carry a risk of potential infectious disease transmission. This case series outlines causes of zoonotic pneumonia associated with cats and dogs, with a particular focus on the three cases presented of respiratory infection with and in patients with an underlying malignancy.

COVID-19 in Immunocompromised Cancer Patients: A Case Series and Review of the Literature.

The global pandemic of the novel coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has presented newfound challenges to the oncology community regarding management of disease progression in immunocompromised and cancer patients. Further, the large influx of COVID-19 patients has overwhelmed healthcare facilities, limited access to intensive care unit beds and ventilators, and canceled elective surgeries causing disruptions to the cancer care continuum and re-organization of oncological care. While it is known that the potential threat of infection is greatest in elderly patients (>60 years of age) and patients with underlying comorbidities, there is still insufficient data to determine the risk of COVID-19 in cancer patients.

Preventing the Spread: A Comprehensive Cancer Center's Journey to Prevent the Spread of Coronavirus Disease (Covid-19) During the 2020 Pandemic.

Background: On March 11, 2020, the World Health Organization (WHO) declared Coronavirus Disease (COVID-19) a pandemic. Hospitals around the world began to implement infection prevention and control (IPC) measures to stop further spread and prevent infections within their facilities. Healthcare organizations were challenged to develop response plans, procure personal protective equipment (PPE) that was in limited supply while continuing to provide quality, safe care.

Prospective CYP2C19-Guided Voriconazole Prophylaxis in Patients With Neutropenic Acute Myeloid Leukemia Reduces the Incidence of Subtherapeutic Antifungal Plasma Concentrations.

A risk mitigation strategy was implemented to determine if a higher prophylactic voriconazole dosage in patients with CYP2C19 rapid metabolizer neutropenic acute myeloid leukemia (AML) reduces the incidence of subtherapeutic trough concentrations. Patients with AML (n = 263) were preemptively genotyped for CYP2C19*2, *3, and *17 alleles as part of a single-center prospective, interventional, quality improvement study. CYP2C19 rapid metabolizers (CYP2C19*1/*17) were recommended to receive interventional voriconazole 300 mg twice daily, ultrarapid metabolizers (CYP2C19*17/*17) were recommended to avoid voriconazole, and all others received the standard prophylactic dosage of 200 mg twice daily.

A Case Series of Infection in Cancer Patients at an Academic Cancer Institute in the United States.

Background: is a coagulase-negative staphylococcus (CoNS) that is a part of the normal human skin flora. Even though it belongs to CoNS family, it can cause severe and destructive infections in a similar fashion to . Skin and soft tissue infections (SSTI), bacteremia and endocarditis are amongst the most common clinical presentations.

Malignancy Trends in HIV-Infected Patients Over the Past 10 Years in a Single-Center Retrospective Observational Study in the United States.

The introduction of antiretroviral therapy (ART) in 1995 had a dramatic impact on the morbidity and mortality of the HIV population, and subsequently, the natural history of cancer has changed. The purpose of our study was to review the prevalence of AIDS-defining malignancies and non-AIDS defining cancers (NADC), taking into consideration racial and gender variations. After the institutional review board approval, the study was conducted as a retrospective chart review of 279 HIV-infected patients who were treated at the Moffitt Cancer Center between January 1, 2000 and December 31, 2010.

Treatment of Enteropathogenic Diarrhea in Cancer Patients: A Series of Three Cases.

Enteropathogenic (EPEC) is a common cause of watery diarrhea in children in the developing world and an infrequent cause of significant diarrhea in adult patients. EPEC diarrhea, while not commonly seen in cancer patients, can cause significant distress to patients, and antimicrobial choice for this condition in this patient population is not clearly delineated in the literature. We report 3 cases of EPEC diarrhea in cancer patients and discuss the use of azithromycin for successful treatment of these patients.

Infectious Risks and Complications in Adult Leukemic Patients Receiving Blinatumomab.

Background: Blinatumomab is an anti-CD19 immunotherapy approved for relapsed/refractory B-cell acute lymphoblastic leukemia (ALL) with significantly increased survival rate. While blinatumomab showed lower rates of infection, neutropenia and mucosal barrier injury versus chemotherapy, its infection risks are not well described.

Methods: All patients who received blinatumomab for ≥ seven days at an academic cancer center from May 2015 to April 2017 were included.

Typhlitis in a Patient with Acute Myelogenous Leukemia: A Case Report and Review of the Literature.

is a Gram-positive rod that is now recognized as a rare cause of frank disease in the neutropenic hematologic malignancy patient. Because this pathogen is rarely isolated in clinical specimens, no large studies exist to guide the management of these acutely ill patients. Individual case reports and case series exist in the literature describing various clinical manifestations of in the neutropenic patient including bacteremia/septicemia, pneumonia, meningitis/encephalitis, hepatic abscesses, and gastritis.

Two cases of disseminated infection following live organism anti-cancer vaccine administration in cancer patients.

Vaccines containing live attenuated bacterial or viral organisms are currently being investigated as potential therapy for locally advanced or metastatic cancers. However, the use of such live organisms in an immunocompromised population, such as patients who recently or are currently receiving chemotherapy, raises the concern that these organisms can themselves disseminate and cause frank infection. We report a hereunto unreported phenomenon of anti-cancer vaccines (containing live attenuated organisms) leading to frank, disseminated infection.

Necrotizing Fasciitis Secondary to Infection Presenting with Septic Shock.

This report describes a case of necrotizing fasciitis presenting with septic shock due to an infection. The patient cut his foot while mowing the lawn and then spent time in a pool with black mold. He began feeling ill and developed swelling and a quarter-sized black area on his right lower extremity.

Mucositis and oral infections secondary to gram negative rods in patients with prolonged neutropenia.

Patients with prolonged neutropenia are at risk for a variety of complications and infections including the development of mucositis and oral ulcers. The changes in oral flora during chemotherapy and its effects on the development of infections of the oral cavity have been studied with inconsistent results. However, there is evidence that supports the colonization of gram negative rods in patients undergoing chemotherapy.

Invasive Haemophilus influenzae Infection in Patients With Cancer.

A major cause of morbidity and mortality in patients with cancer is infection. Since the introduction of the Haemophilus influenzae type b (Hib) vaccine in the United States in the 1990s, invasive H influenzae infection has become less common. We report on 5 patients with cancer and invasive H influenzae infection.

Infectious Causes of Right Middle Lobe Syndrome.

Right middle lobe (RML) syndrome is defined as recurrent or chronic obstruction or infection of the middle lobe of the right lung. Nonobstructive causes of middle lobe syndrome include inflammatory processes and defects in the bronchial anatomy and collateral ventilation. We report on 2 case patients with RML syndrome, one due to infection with Mycobacterium avium complex followed by M asiaticum infection and the other due to allergic bronchopulmonary aspergillosis.

Use of tigecycline for the management of Clostridium difficile colitis in oncology patients and case series of breakthrough infections.

Background: Clostridium difficile infection (CDI) is the most frequent cause of nosocomial diarrhoea in adults. Cancer patients, in particular, are at a higher risk for CDI. Limited clinical data exist regarding the use of tigecycline for the treatment of CDI, especially in patients with oncologic and haematologic malignancies.

A Case of Refractory Pulmonary Coccidioidomycosis Successfully Treated with Posaconazole Therapy.

Coccidioidomycosis is an endemic fungal infection caused by the inhalation of the spores of species. Patients with underlying immunosuppressive illness can contract chronic or disseminated disease which requires prolonged systemic therapy. Pulmonary coccidioidomycosis remains as an illusory and abstruse disease, with increased prevalence that poses as a challenge for clinicians in developing an effective strategy for treatment.

Human Metapneumovirus Infection in Immunocompromised Patients.

Human metapneumovirus (HMPV) is a pathogen associated with respiratory tract infection and is related to avian pneumovirus. Typically, children, the elderly, and those who are immunocompromised are the most susceptible to HMPV infection; however, the virus can infect persons of all ages. In otherwise healthy individuals, HMPV infection is generally self-limiting, but immunocompromised individuals can develop fatal complications.

Marijuana Smoking in Patients With Leukemia.

Worldwide, marijuana (cannabis) is a widely used drug. The incidence of marijuana smoking is increasing and is second only to tobacco as the most widely smoked substance in the general population. It is also the second most commonly used recreational drug after alcohol.

Primary Gangrenous Cutaneous Mold Infections in a Patient With Cancer and Neutropenia.

Background: Opportunistic fungal infections caused by Aspergillus and Candida followed by infections with Fusarium, Rhizopus, Mucor, and Alternaria species are an important cause of morbidity and mortality in patients with hematological malignancies. Cutaneous mucormycosis infections are rare, and the incidence, outcomes, and factors associated with survival in the setting of hematological malignancies are not clear.

Methods: A literature search was conducted for all cases of primary cutaneous mold infections in patients with hematological malignancy, of which 50 cases were found.
