Treatment opportunistic infections

Gable et al. (1996) estimated lifetime costs of treating a person with HIV to be US 94,726, using an expert panel and several cost data sources to produce treatment protocols for opportunistic infections and primary antiretroviral therapy.

Staphylococcus, Moraxella, or other opportunistic bacteria typically cause chronic conjunctivitis.10 Moraxella infections may cluster in groups of women who share makeup.12 Both acute and chronic bacterial conjunctivitis are self-limiting except if caused by staphylococci.13 Because of this, the pathogens are rarely cultured unless the case is unresponsive to treatment. While infection typically begins in one eye, it will often spread to both within 48 hours.11... 

O The treatment goals for HIV infection are to maximally and durably suppress HIV replication, avoid the development of drug resistance, restore and preserve immune function, prevent opportunistic infections, and minimize adverse effects. 

HIV RNA plasma concentrations and CD4+ T-cell counts are used to assess risk of progression to AIDS (or risk for opportunistic infection) and to monitor efficacy and durability of treatment. 

Effective and complete treatment of HIV infection involves a multidisciplinary approach, which includes pharmacists, clinicians, social workers, and others. Treatment of HIV infection always requires combination prescription antiretroviral therapy, and may include prescription treatment or prophylaxis for opportunistic infections, and prescription or nonprescription treatment for adverse effects. 

Degree of immune function preservation also correlates with decreased viral replication, and is measured by CD4+ T-cell counts. CD4 measures are the best predictor of progression to AIDS, and help decide when to initiate treatment. At CD4+ T-cell counts of 200 cells/mm3 and lower, patients require drug prophylaxis for opportunistic infections. Table 84—2 details the monitoring endpoints of HIV treatment for HIV RNA and CD4+ T-cell counts. 

Alemtuzumab is the antibody to the CD52 receptor present on B and T lymphocytes. The pharmacokinetics of alemtuzumab demonstrate a terminal half-life of 7 days. Alemtuzumab has shown clinical activity in the treatment of chronic lymphocytic leukemia. Severe and prolonged (6 months) immunosuppression may result, which necessitates prophylaxis with cotrimox-azole and antivirals to prevent opportunistic infections.

The major problems for AIDS patients generally are the opportunistic infections that result from the lack of immunological protection. Thus, development of better therapies for these infections will play an important role in improved treatment of AIDS patients.

Nelfinavir is indicated for the treatment of human immunodeficiency virus (HIV) infection when antiretroviral therapy is warranted. At present, there are no results from controlled trials evaluating the effect of therapy with nelfinavir on clinical progression of HIV infection, such as survival or the incidence of opportunistic infections. 

Opportunistic infections During the initial phase of treatment, patients responding to antiretroviral therapy may develop an inflammatory response to indolent or residual opportunistic infections. 

As opportunistic infections (OIs) are common in HIV/AIDS and as their treatment is part of the cost-effectiveness considerations of ART in RLS, requirements for the diagnosis of different OIs are listed in Table 3. Due to the significant burden of tuberculosis in HIV-infected individuals and its contribution to early mortality in cohorts of individuals initiating ART, screening for active TBC in individuals before initiating ART is generally recommended. 

The prevention and treatment of opportunistic infections (OIs) in the ART era is still an important component of HIV care in RLS for three major reasons. First of all, many individuals present with life threatening OIs as the first indication of HIV infection. The proportion of the population at risk for HIV infection that is aware of its HIV serostatus is considerably very low. Secondly, whereas over the last two years access to ART has improved greatly, ART coverage in RLS is still less than 25% of the ART eligible population. 

The reason that it was decided to discuss the treatment of tuberculosis in a chapter together with HIV/AIDS is because tuberculosis is the most deadly opportunistic infection in people with HIV/AIDS, certainly in resource poor settings. We still felt that in this chapter tuberculosis should be a section on its own as also outside the HIV/AIDS context, tuberculosis poses a grave and growing threat to global public health.

NK cells, monocytes, macrophages, and a small population of granulocytes. Currently, alemtuzumab is approved for the treatment of -cell chronic lymphocytic leukemia in patients who have been treated with alkylating agents and have failed fludarabine therapy. Alemtuzumab appears to deplete leukemic and normal cells by direct antibody-dependent lysis. Patients receiving this antibody become lymphopenic and may also become neutropenic, anemic, and thrombocytopenic. As a result patients should be closely monitored for opportunistic infections and hematologic toxicity. 

Stopping HIV is not the only avenue for research. Much work is proceeding on drugs to treat or prevent the opportunistic infections which prey upon immune deficient victims. Aerosol pentamidine was approved several years ago for the prophylaxis and treatment of pneumocystis infection.

Antiviral agents (qv) (15—17) are used in attempts to combat the devastating effect of HIV on the immune system. As of this writing there are three principal approaches to the treatment of AIDS (/) use of anti-HIV agents to destroy the virus or control its growth the National Cancer Institute (NCI) encourages submission of synthetic and characterized natural products for anti-HIV screening (18) (2) immunotherapy to restore impaired immune functions and (3) treatment of specific opportunistic infections or tumors. 

The treatment of patients with AIDS and individuals infected by HIV is continually being modified as new drugs become available and more information is gained about the nature of the AIDS virus. Currently, the pharmacologic management of HIV-infected patients consists of two principal strategies (1) controlling the proliferation and effects of HIV in individuals infected with this virus and (2) treatment and prevention of various opportunistic infections that...
