Emerging Nanotechnology in Chronic Respiratory Diseases

A large population, including people of all age groups, is suffering from chronic respiratory diseases worldwide. Asthma, chronic obstructive pulmonary disease, occupational lung diseases, cystic fibrosis, etc. are the most common of these diseases and are noncurable with conventional and currently available therapies. Nanotechnology is emerging as a great therapeutic promise in different spheres including drug delivery systems and is becoming the technology of choice nowadays. The administration of drugs via inhalation helps in avoiding the first-pass metabolism by targeted delivery to the affected site. It has been observed that there is a huge diversity in nanotechnology being used in pulmonary diseases, and thus safety assessment is a challenging as well as important task. The present review focuses on some of the major emerging nanotechnologies for chronic pulmonary diseases and includes some of the latest studies in the field of nanomedicines

The immune reconstitution inflammatory syndrome related to HIV co-infections: a review

The immune reconstitution inflammatory syndrome (IRIS) is a consequence of an excessive pathogen-specific immune recovery reaction and occurs in a subset of patients on antiretroviral therapy (ART). Infective forms of IRIS may present either as an 'unmasking' of a previously subclinical infection or the paradoxical clinical deterioration of an infection for which the patient received appropriate antimicrobial therapy. The most important risk factors for IRIS are a low CD4+ T-cell count and a short time between treatment of the infection and the commencement of ART. The general approach to the treatment of IRIS is to continue ART and provide antimicrobial therapy for the provoking infection. The majority of cases are self-limiting; however, mortality and hospitalisation rates are particularly high when tuberculosis- or cryptococcal-IRIS affects the central nervous system (CNS). Corticosteroid therapy should be considered in certain forms of IRIS after the exclusion of other conditions that could explain the inflammatory manifestations in the patients. Given that a low CD4+ T-cell count is a major risk factor for the development of IRIS, commencing ART at a CD4+ T-cell count of >350/muL will prevent most cases
