Management of HIV-infected patients in the intensive care unit.

The widespread use of combination antiretroviral therapies (cART) has converted the prognosis of HIV infection from a rapidly progressive and ultimately fatal disease to a chronic condition with limited impact on life expectancy. Yet, HIV-infected patients remain at high risk for critical illness due to the occurrence of severe opportunistic infections in those with advanced immunosuppression (i.e., inaugural admissions or limited access to cART), a pronounced susceptibility to bacterial sepsis and tuberculosis at every stage of HIV infection, and a rising prevalence of underlying comorbidities such as chronic obstructive pulmonary diseases, atherosclerosis or non-AIDS-defining neoplasms in cART-treated patients aging with controlled viral replication. Several patterns of intensive care have markedly evolved in this patient population over the late cART era, including a steady decline in AIDS-related admissions, an opposite trend in admissions for exacerbated comorbidities, the emergence of additional drivers of immunosuppression (e.g., anti-neoplastic chemotherapy or solid organ transplantation), the management of cART in the acute phase of critical illness, and a dramatic progress in short-term survival that mainly results from general advances in intensive care practices. Besides, there is a lack of data regarding other features of ICU and post-ICU care in these patients, especially on the impact of sociological factors on clinical presentation and prognosis, the optimal timing of cART introduction in AIDS-related admissions, determinants of end-of-life decisions, long-term survival, and functional outcomes. In this narrative review, we sought to depict the current evidence regarding the management of HIV-infected patients admitted to the intensive care unit.

Varicella pneumonia in patients with HIV/AIDS.

OBJECTIVE: To determine the potential role of steroid therapy combined with early antiviral and supportive care in patients infected with human immunodeficiency virus (HIV) with varicella pneumonia. MATERIALS AND METHODS: A retrospective review was conducted of the incidence, clinical course, and outcome of varicella pneumonia in patients with HIV or acquired immunodeficiency syndrome (AIDS). RESULTS: Seven of 12 patients (58%) who were hospitalized with chickenpox developed clinically severe varicella pneumonia. All patients had advanced immunosuppression and all developed diffuse reticulonodular radiographic abnormalities, although two patients had normal chest radiographs on admission. All patients received antiviral therapy within 12 hours of hospital admission. The overall mortality rate was 43%. Six patients were treated with systemic corticosteroids in addition to antiviral agents, including all four of the survivors. CONCLUSIONS: Hospitalized patients with HIV or AIDS with chickenpox are at high risk for developing varicella pneumonia. There is a potentially high rate of death despite prompt initiation of appropriate antiviral therapy. Intensive care management and adjunctive use of systemic corticosteroids may improve outcome.
