System nutritional therapies

Highly Active Antiretroviral Therapy (HAART) HAART slows or inhibits reverse transcriptase and protease enzymes by using several antiretroviral agents. HAART decreases the viral load. The viral load measures the amount of virus in the body. A decreased viral load causes an increase in CD4+ T cells and results in the immune system being able to identify, neutralize, and destroy non-self-cells. HAART therapy must be adhered to because the virus can become resistant to the antiretroviral agents. The patient must also adhere to nutritional therapy and avoid infections. 

It is expected that intensive research will be carried out to explore original and unexpected toxicity antidote applications of fat nanoemulsions traditionally used as components of parenteral nutrition therapy. Recently, these authors reviewed the potential role of fat nanoemulsions in treatment of toxicity due to local anesthetics and other lipid-soluble drugs. Litz and coworkers [2008] reported in a 91-yr-patient the reversal of central nervous system and cardiac toxicity after local... 

Overall, nutrition therapy is a component of medical treatment that includes oral, enteral, and parenteral nutrition (PN). However, a meta-analysis provided no evidence that nutritional support has a significant effect on anthropometric measures, lung function, or exercise capacity in patients with stable COPD (25,26). By contrast, repeated administration of ghrelin, a novel growth hormone- releasing peptide that is reduced in COPD (27), may improve body composition, muscle wasting, and functional capacity in cachectic patients with COPD, thus possibly reversing some of the systemic aspects of COPD (28). 

Other causes include magnesium-containing antacids in patients with renal insufficiency, enteral or parenteral nutrition in patients with multiorgan system failure, magnesium for treatment of eclampsia, lithium therapy, hypothyroidism, and Addison s disease. 

MedWatch program. The FDA recently established the Special Nutritionals Adverse Event Monitoring System, a searchable database including information about suspected adverse events associated with dietary supplements or nutritional products. This database includes reports that have been submitted to MedWatch and can be accessed via the Internet (http //vm.cfsan.fda.gov/ dms/ aems.html). Continued efforts by health-care professionals to recognize and report suspected interactions between prescription medications and herbal and other alternative therapies should ultimately increase knowledge and awareness of interactions and improve the quality of patient care (see Heck et al., 2000 Izzo, 2004 Butterweck, 2004 Chan, 2005). 

Cancer patients often develop symptoms from organs remote from the primary tumor. The symptoms are usually caused by metastasis or toxic effects of therapy and less often by such secondary factors as nutritional deficiency, metabolic disturbances, opportunistic infections, and effects of critical illness. Other systemic diseases such as diabetes or amyloid may become manifest or aggravated during the course of the cancer disease and cause symptoms from remote organs. Paraneoplastic neurological syndromes (PNS) are a rare cause of remote symptoms [1]. The PNS affect less than 1% of all cancer patients [2], Even in small cell lung cancer (SCLC), the tumor type most commonly associated with PNS, these disorders occur in less than 5% of the patients [3, 4],... 

Two children developed neurological complications of fat emulsion therapy, including focal and generalized seizures, weakness, and altered mental status, before any systemic findings were in evidence (15). Biopsy and autopsy findings included cerebral endothehal and intravascular lipid deposition. These complications are potentially reversible with alteration of the parenteral nutrition content, highlighting the importance of their early recognition. 

Most hospitals have a computerized CIVAS that is integrated into the unit-dose distribution system. Preparations handled in these units include cytotoxic drugs, antibiotics, parenteral nutrition, other drugs, and therapy with fluids (Fig. 4). References to Spanish articles dealing with recommendations for managing these units can be found in the bibliography.Protocols must include every procedure carried out in the unit, from preparation to identification, hazard handling, waste treatment, and so on. In Spain, admixtures and nutritional preparations are normally prepared by pharmacy nurses supervised by pharmacists.

Because nearly 70% of patients who use alternative therapies do not inform their health-care providers about these products, pharmacists and other health-care professionals should question all patients about their use of alternative therapies. Health-care professionals should remain vigilant for potential interactions between alternative therapies and prescription medications, especially medications with a narrow therapeutic index, and should report suspected interactions to the FDA MedWatch program. The FDA recently established the Special Nutritionals Adverse Event Monitoring System, a searchable database including information about...
