The salicylates and nonsteroidal anti-inflammatory drug (NSAIDs) are important in the treatment of arthritic conditions. For example, the salicylates and NSAIDs are used in the treatment of rheumatoid arthritis (a chronic disease characterized by inflammatory changes within the body s connective tissue) and osteoarthritis (a noninflammatory joint disease resulting in degeneration of the articular cartilage and... 

Although the use of barbiturates and miscellaneous sedatives and hypnotics for sedation has largely been replaced by the antianxiety drugs (see Chap. 30), they occasionally may be used to provide sedation before certain types of procedures such as cardiac catheterization or the administration of a local or general anesthesia Sedative doses usually given during daytime hours, may be used to treat anxiety and apprehension. Fhtients with chronic disease may require sedation, not only to reduce anxiety, but also as an adjunct in the treatment of their disease...

Alcoholics Anonymous (AA) is a self-help organization for people whose common goal is recovery from alcoholism, and it is the most widely accessed resource for individuals with alcohol problems (McCrady and Miller 1993). The philosophy is based on the concept of alcoholism as a chronic disease that cannot be cured, but one that can be halted by means of complete abstinence. AA has described 12 principles or steps to guide those in recovery. Twelve-step facilitation, a manual-based psychotherapy to promote AA participation (Nowinski et al. 1992), was equally efficacious, compared with cognitive-behavioral and motivational enhancement therapies, in a large study of treatments for alcohol dependence (Project Match Research Group, 1997). 

Only one study to date has been conducted on the treatment of acute pancreatitis with antioxidants. Clemens et al. (1991) were unable to show any difference in the incidence or severity of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in a prospective, randomized, double-blind, placebo-controlled trial of allopurinol. However, Salim (1991) performed a similar trial of the effect of allopurinol and DMSO in patients with pain from recurrent pancreatitis, and found significant benefit. On the basis that depletion of antioxidants is important in the pathogenesis of chronic pancreatitis, the administration of a cocktail of antioxidants was assessed for its effect on pain in this disease. Treatment with a combination of organic selenium, d-carotene, vitamins C and E, and methionine was of benefit in the initial pilot study, and in a placebo-controlled trial (San-dilands etal., 1990 Uden et al., 1990). 

Patients must understand the role of long-term control and quick relief medications in their asthma treatment plan. The importance of understanding asthma as a chronic disease and the need for daily treatment with long-term control medications should be stressed. Additionally, the importance of proper use of medication delivery devices should be continually reinforced. Basic education should be provided over several visits with the health care provider. 

Patients with viral hepatitis B, C, and D may develop chronic disease leading to ESLD. Treatment is only available for chronic liver disease associated with HBV, HCV, and HDV.20,21... 

Many women seek medical treatment for the relief of menopausal symptoms, primarily hot flashes however, the role of hormone-replacement therapy (HRT) has changed dramatically over the years. HRT has long been prescribed for relief of menopausal symptoms and, until recent years, has been purported to protect women from CHD. The original reason behind recommending HRT in postmenopausal women revolved around a simple theory If the hormones lost during menopause were replaced through drug therapy, women would be protected from both menopausal symptoms and chronic diseases that often follow after a woman experiences menopause. Recent studies have disproved this theory. 

In summary, combined estrogen plus progestin should not be used for the prevention of chronic diseases because it increases the risk of CHD, stroke, breast cancer, and venous thromboembolism. However, colorectal cancer and rates of fracture were reduced with combined hormonal treatment. 

Methotrexate has been used successfully with cyclosporine, either concurrently34 or in rotation. Rotational therapy is particularly effective since it minimizes the serious adverse effects of both agents hepatotoxidty from methotrexate and hypertension and nephrotoxicity from cyclosporine. Having an overlapping treatment period may not be necessary and patients have been successfully switched after a 1-week washout period.21,35 This is a very useful combination of systemic agents in the longterm management of this chronic disease. 

The underlying cause of anemia (e.g., blood loss iron, folic acid, or vitamin B12 deficiency or chronic disease) must be determined and used to guide therapy. As discussed previously, patients should be evaluated initially based on laboratory parameters to determine the etiology of the anemia (see Fig. 63-3). Subsequently, the appropriate pharmacologic treatment should be initiated based on the cause of anemia. 

SCD treatment and prevention are considered successful when complications are minimized. The major outcome parameters are a decrease in morbidity and mortality, measured by the number of hospitalizations, and the extent of end-organ damage seen over time. SCD is a chronic disease that cannot be cured, except with transplantation. 

The goals of treatment for ABRS are to eradicate bacteria and prevent serious sequelae. Specific aims are to relieve symptoms, normalize the nasal environment, use antibiotics when appropriate, select effective antibiotics that minimize resistance, and prevent development of chronic disease or complications. 

In the treatment of chronic diseases, a long term zero order release dosage form is highly desirable as it reduces fluctuations of drug levels, reduces toxicity and increases patient compliance. Problems in the treatment of both hypertension, a lifetime disorder, and opiate addiction are associated with compliance. The goal of this research is to develop a subcutaneously injectable system which can release drug at constant rates over a long period of time. 

The promise of the isolation and production of therapeutic polypeptides and proteins demands that for treatment of a chronic disease state an oral delivery system be developed which will protect these valuable agents from the hostile gastric environment. Subsequently, the drugs will have to be completely released in the intestine, preferably in a state that will enhance their rapid dissolution and transport across the gut wall minimizing interaction with intestinal proteases. 

In the case of chronic processes, the patient can, at any time, take the decision to stop the treatment, as a reaction to changes in price or other variables. Whereas the econometric technique for analysing the demand for pharmaceuticals for acute processes is that of discrete choice models, here we will apply duration or survival models. In addition, the technology of drags for chronic diseases can have non-constant returns to scale. For example, the consumption of anxiolytics raises the tolerance and reduces the effect, resulting in an increase in the necessary dose. 

The release characteristics of polyanhydride systems could be used not only to develop clinical treatments, but also to induce chronic disease states as models for studying immune function. Many current models of chronic diseases are based on induction of acute effects, which do not exhibit the same long-term behavior as the disease being modeled. 

Treatment for HCV infection is necessary because a high percentage of acutely infected patients develop chronic infections. Treatment is indicated in patients previously untreated who have chronic HCV, circulating HCV RNA, increased alanine transaminases levels, evidence on biopsy of moderate to severe hepatic grade and stage, and compensated liver disease. 

Treatment of anemia of chronic disease is less specific than that of other anemias and should focus on correcting reversible causes. Iron therapy is... 

In a patient with chronic respiratory acidosis (e.g., chronic obstructive pulmonary disease), treatment is essentially similar to that for acute respiratory acidosis with a few important exceptions. Oxygen therapy should be initiated carefully and only if the Pao2 is less than 50 mm Hg because the drive to breathe depends on hypoxemia rather than hypercarbia.
