Adoptive cellular immunotherapy is a promising and powerful method for the treatment of a broad range of malignant and infectious diseases. Although the concept of cellular immunotherapy was originally proposed in the 1990s, it has not seen successful clinical application until recent years. Despite significant progress in creating engineered receptors against both malignant and viral epitopes, no efficient preclinical animal models exist for rapidly testing and directly comparing these engineered receptors...

Onychomycosis accounts for 50% of all nail disease cases and is commonly caused by dermatophytes. Diabetes, human immunodeficiency virus, immunosuppression, obesity, smoking, and advancing age are predisposing factors of this fungal infection. Potassium hydroxide and culture are considered the current standard for diagnosing onychomycosis, revealing both fungal viability and species identification. Other diagnostic tests currently available include periodic acid-Schiff staining, polymerase chain reaction techniques, and fluorescent staining...

Invasive fungal and fungal-like infections contribute to substantial morbidity and mortality in immunocompromised individuals. The incidence of these infections is increasing-largely because of rising numbers of immunocompromised patients, including those with neutropenia, human immunodeficiency virus, chronic immunosuppression, indwelling prostheses, burns, and diabetes mellitus, and those taking broad-spectrum antibiotics. Invasive fungal pathogens include primary mycotic organisms such as Histoplasma capsulatum, Coccidioides immitis, Blastomyces dermatitidis, and Paracoccidioides brasiliensis, which are true pathogens and inherently virulent...

Ramsay Hunt syndrome (or herpes zoster oticus) is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus infection in the geniculate ganglion occurs. Usually, there are auricular vesicles and symptoms and signs such otalgia and peripheral facial paralysis. In addition, rarely, a rash around the mouth can be seen. Immunodeficient patients are more susceptible to this condition. Diagnosis is essentially based on symptoms. We report the case of a diabetic female patient who sought the emergency department with a complaint of this rare entity...

BACKGROUND: Wellens syndrome is a pattern of electrocardiographic (ECG) changes in the context of unstable angina characterized with deep inverted T-waves or biphasic T-waves in the precordial leads. These specific ECG changes are highly suggestive of stenosis in the left anterior descending artery (LAD), which can result in acute myocardial infarction, left ventricular dysfunction, or death. Human immunodeficiency virus (HIV) infection is known as an independent risk factor for the cardiovascular disease...

BACKGROUND: With the advent of effective antiretroviral therapy, the care of patients with human immunodeficiency virus infection became more like that of other chronic diseases. Diabetes mellitus can also occur as one of the chronic illnesses affecting patients with human immunodeficiency virus infection. We report a case of newly developed diabetes mellitus in a patient with human immunodeficiency virus infection, most likely caused by the nucleoside analogue zidovudine, and its improvement after discontinuation of zidovudine...

Ceramide is a glycosphingolipid, a component of nerve and non neuronal cell membrane and plays a role in maintaining the integrity of neuronal tissue. Butyrylcholinesterase (BChE) is a multifunctional enzyme, its involvement in neurodegenerative diseases has been well established. Anticeramide antibody (Ab-Cer) and enzyme BChE have been implicated in peripheral neuropathies. The present study investigates whether there is an association between Ab-Cer and BChE activities and peripheral neuropathies. Patients included: human immunodeficiency virus associated peripheral neuropathy (HIV-PN, n=39), paucibacillary leprosy (PB-L, n=36), multibacillary leprosy (MB-L, n=52), diabetic neuropathy (DN, n=22), demyelinating sensory motor polyneuropathy (DSMN, n=13) and chronic inflammatory demyelinating polyneuropathy (CIDP, n=10)...

Infection with Mycobacterium tuberculosis predominantly establishes subclinical latent infection over the lifetime of an individual, with a fraction of infected individuals rapidly progressing to active disease. The immune control in latent infection can be perturbed by comorbidities such as diabetes mellitus, obesity, smoking, and coinfection with helminthes or HIV. Modeling the varying aspects of natural infection remains incomplete when using zebrafish and mice. However, the nonhuman primate model of tuberculosis offers a unique and accurate model to investigate host responses to infection, test novel therapeutics, and thoroughly assess preclinical vaccine candidates...

This report describes an unusual case of an insidiously enlarged traumatic palatal perforation after orotracheal intubation in a four-year-old female child with Insulin Dependent Diabetes Mellitus (IDDM). The child was first diagnosed with diabetes at 10 months of age when she was hospitalized for pneumonia. Severe respiratory distress warranted assisted ventilation via orotracheal intubation. Multiple factors namely infection, relative immunodeficiency, poor wound healing, trauma via orotracheal intubation as well as uncontrolled glucose levels, all contributed to the formation and deterioration of the palatal perforation...

Miliary tuberculosis results from the lymphohematogenous spread of Mycobacterium tuberculosis and it is a rare form of this disease. The most affected places are the lymph nodes, pleura, and osteoarticular system, but any organ can be involved. Currently the disease is still endemic in developing countries by its close association with poor living conditions and malnutrition. Other comorbidities, particularly infection by human immunodeficiency virus (HIV), diabetes mellitus, smoking and alcoholism are of great importance in the epidemiology of this disease...

The immune system protects our body against foreign pathogens. However, if it overshoots or turns against itself, pro-inflammatory diseases, such as rheumatoid arthritis, inflammatory bowel disease, or diabetes develop. Ions, the most basic signaling molecules, shape intracellular signaling cascades resulting in immune cell activation and subsequent immune responses. Mutations in ion channels required for calcium signaling result in human immunodeficiencies and highlight those ion channels as valued targets for therapies against pro-inflammatory diseases...

The prevalence of diabetes is higher amongst individuals infected with HIV. The major contributor to hyperglycaemia is thought to be iatrogenic, with protease inhibitors being most commonly associated to insulin resistance. This article is to update general practitioners on the diagnosis and management of diabetes in HIV-infected patients. Specific considerations are highlighted including interactions of particular diabetic drugs with antiretroviral therapy (ART). We articulate why the use of Hemoglobin A1c (HbA1c) testing is not recommended as a diagnostic tool...
