In a series of studies, recombinant interferon-alpha 2a (rIFN alpha 2a, Roferon-A) was administered alone (273 men) or combined with vinblastine (91 men) to patients with acquired immunodeficiency syndrome (AIDS)-related Kaposi's sarcoma (KS). Patients were treated with daily doses of rIFN alpha 2a ranging from 3 to 54 million international units (I.U.) administered intramuscularly. A dose of 36 million I.U. daily for approximately 10 weeks followed by a three times weekly maintenance schedule with the same dose resulted in the best overall therapeutic benefit. An escalating-dose regimen of 3, 9, and 18 million I.U. daily, each for 3 days, followed by 36 million I.U. daily, produced equivalent therapeutic benefit with amelioration of acute toxicity in some patients. Response was more likely in patients without a history of
opportunistic infection
or B symptoms (fever, night sweats, or weight loss). Response rate increased with increasing baseline CD4 lymphocyte count and was 45.5% in patients with a CD4 count of greater than 400/mm3. Responding patients with a CD4 count of greater than 200/mm3 had a distinct survival advantage over patients who had similar CD4 counts but whose tumors did not regress with therapy. The addition of vinblastine increased toxicity and did not improve the response rate or prolong survival. Side effects included fatigue, fever, chills, myalgias, headaches, anorexia, nausea, diarrhea, and

. Mild abnormalities in hematologic and liver function tests occurred in some patients. Most adverse effects diminished or resolved with continued therapy. We conclude that rIFN alpha 2a offers important therapeutic benefit in a select group of patients with AIDS-related KS.

In this discussion of infection control in patients with acquired immune deficiency syndrome (AIDS), attention is directed to nursing. Due to the fact that the majority of individuals who suffer with AIDS will be homosexual, intravenous drug users, or both, it is essential that the nurse historian be aware of his/her own feelings about the lifestyles of these patients. History-taking should be done in a nonjudgmental manner. A major pitfall to be avoided when taking a history is making assumptions about an individual's sexual preferences or activities based on the response to a simple question about marital status. It is important to note whether or not the person has a monogamous relationship or leads a polyandrous lifestyle. Another area that should be tactfully but explicitly explored when interviewing an individual who is homosexual or bisexual is the number of different sexual partners that he/she has been involved with on a weekly or monthly basis. Whether the patient has a history of sexually transmitted diseases should be determined. The use of recreational drugs should be explored. When taking the history of a client who uses intravenous drugs, it is important for the nurse to record the agents and sites of injection as well as to note whether the individual uses his/her own equipment. When reviewing the major body systems and the presence or absence of related symptoms, the nurse should note whether the client has experienced skin rashes/lesions, swollen lymph nodes, fever, extreme fatigue, weight loss, shortness of breath, changes in bowel habits, cuts or bruises that do not heal, and headaches,

, blurred vision, or stiff neck. The physical examination of the individual with AIDS and an
opportunistic infection
usually will reveal positive findings in the central nervous system, respiratory system, gastrointestinal system, and/or the integumentary system, as well as the lymphatic system. As the leading cause of morbidity in the compromised host is infection, infection prevention should be regarded as a pragmatic necessity. 2 major things that nurses can do in the acute care setting to control infection are to limit the frequency of invasive or traumatic procedures and to reduce the acquisition of new potential pathogens.

Disseminated histoplasmosis is an
opportunistic infection
encountered in immunocompromised patients such as those with human immunodeficiency virus infection/acquired immune deficiency syndrome. Involvement of the central nervous system (CNS) can occur in 5-20% of cases of disseminated histoplasmosis, and CNS histoplasmosis can be very difficult to diagnose
via
conventional imaging modalities such as CT or MRI. The role of
18
F-fludeoxyglucose positron emission tomography/CT scan in the diagnosis of CNS histoplasmosis has not been established. A 66-year-old female presented with
dizziness
and unsteady gait and was diagnosed with human immunodeficiency virus infection and CNS histoplasmosis. In this report, we present the MRI and
18
F-fludeoxyglucose positron emission tomography/CT image findings.
