Pneumocystis carinii pneumonia (PCP) is the most frequently occurring opportunistic infection in individuals infected with the human immunodeficiency virus. Improved methods of diagnosing and treating PCP have resulted in increased survival rates. Nurses are more frequently faced with treatment of the critical care patient with PCP. Knowledge about the mechanisms and manifestations of PCP as well as its diagnosis and treatment provides a baseline for the nursing management of PCP. Nursing care for the critically ill adult patient with PCP focuses on the management of the human responses to PCP including hyperthermia, impaired gas exchange, altered respiratory function, fatigue, and altered nutrition, and on the management of the side effects of treatment including nausea, vomiting, and hypoglycemia. Effective interventions related to these patient problems can improve the quality of care and ultimately affect patient outcomes.

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 dizziness. 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.

Deferoxamine (DFO) has been widely used in the treatment of aluminum toxicity in patients on chronic dialysis. Mucormycosis is an opportunistic infection caused by fungi of the Mucorales order and some reports suggested a role for DFO in the precipitation of this infection. A 50-year-old man had been on hemodialysis for 16 years. 6 weeks before admission, he was begun on DFO because of aluminum toxicity. 2 weeks before admission, general fatigue and fever developed and followed by headache and loss of vision. He was admitted to this hospital with disturbed consciousness. His clinical course and a CT scan of the head suggested cerebral infarction. Within 24 hours he required ventilatory support and died 5 days after the admission. On autopsy, rhino-cerebral mucormycosis was demonstrated with a mycotic thrombus involving the left middle cerebral artery. Dialysis-related mucormycosis has recently appeared in the literature. We feel that hemodialysis patients on DFO may be at risk for potentially fatal mucormycosis infections. With a possible relationship between DFO treatment and this fatal opportunistic infection, caution should be given before using this drug and the indications should be definitive.

Tumor necrosis factor (TNF) has demonstrated antitumor activity against a variety of tumors and is particularly cytotoxic to capillary endothelial cells, which are the presumed cell of origin of Kaposi's sarcoma. We evaluated the toxicity and clinical antitumor and antiretroviral effects of recombinant TNF administered at a once weekly dose of 100 micrograms/m2 intravenously for 8 weeks in five men with AIDS-related Kaposi's sarcoma and without prior opportunistic infection. One patient was removed from study at week 4 due to rapid progression of Kaposi's sarcoma, another patient with stage IV disease and a pretreatment CD4 count of 11 developed fever, hypotension, and pneumonia at week 7 and died 8 days after discontinuing recombinant TNF. No pathogenic organisms were isolated. He had marked eschar formation of his Kaposi's sarcoma lesions, particularly in areas previously exposed to radiation therapy. Uniform toxicities included fevers, rigors, and headaches during drug infusion that were ameliorated by prophylactic meperidine hydrochloride and acetaminophen. All experienced fatigue and three had arthralgias. One patient had transient hypotension which corrected with i.v. fluids. No significant hematologic, hepatic, or renal toxicities were seen. All patients had some progression of their Kaposi's sarcoma on study. There was no change in CD4 or CD8 count or in CD4:CD8 ratios. Serum human immunodeficiency virus (HIV) p24 antigen levels increased greater than 50% in three patients. We conclude that, as a single agent, at a dose of 100 micrograms/m2 recombinant TNF by i.v. infusion has no obvious antitumor or antiretroviral effects in patients with AIDS-related Kaposi's sarcoma.

Forty-one homosexual men with the acquired immune deficiency syndrome (AIDS) or AIDS-related complex were treated with 0.5, 1.0, or 1.5 g of suramin weekly for up to six months. In no patient was evidence of symptomatic improvement or regression of Kaposi's sarcoma shown. Opportunistic infections developed in 16 patients during therapy. Only six patients (15 percent) became human immunodeficiency virus (HIV) culture-negative during treatment, despite documentation of adequate serum suramin levels. All but one of these six have had disease progression. Decreases in the numbers of total T4 cells with time were observed in both AIDS and AIDS-related complex subgroups. Toxicity was significant and consisted of fatigue, fever, and hepatic and renal dysfunction, all of which were observed most frequently with the 1.0 or 1.5 g dosages. Fatal hepatic failure developed in two patients, and adrenal insufficiency was documented in eight patients. Suramin is a toxic agent that shows no virologic, immunologic, or clinical benefit in patients with HIV-related disease.

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, dizziness, 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.

This paper presents clinical data on 41 patients (29 male and 12 female) from Haiti who presented with acquired immunedeficiency syndrome (AIDS). Their mean age was 32 years (range 17-61 years). 4 of thes cases were homosexual or bisexual; none was an illicit drug user or a hemophiliac. In addition, 3 of the female patients had sexual contact with a male partner with AIDS. 4 patients had received blood transfusions before their illness. The most prominent clinical symptom in this series was chronic diarrhea of 2-33 months' duration, which occurrred in 39 patients (95%). Also reporte were marked weight loss (95%), fatigue (95%), prolonger fever (90%), and nodular or maculopapular skin lesions (54%). Opportunistic infections in this series included oroesophageal candidiasis (88%) and intestinal cryptosporidiosis (31%). Tuberculosis developed in 22% of patients. Immunologic evaluation revealed profoundly depressed T-helper cells and an inverted T-helper/T-suppressor cell ratio. Biologic markers included elevated alpha-1 thymosin and beta-2 microglobulin levels, elevated immune complexes, and the presence of acid-labile interferon. Of interest were differences in the clinical expression of AIDS between this series and cases in the US. The Haitian data suggest a higher incidencs of female cases,a predominance of gastrointestinal symptoms rather than respiratory symptoms and lymphadenopathy, a frequent association with tuberculosis, and a relatively low incidence of Kaposi's sarcoma or P. carinii pneumonia compared to the situation in the US. As in the US, where most AIDS cases are concentrated in New York and California, most AIDS cases in Haiti are found in residents of Port-au-Prince and Carrefour, which are centers for male and female prostitution.

A 74-year-old man was admitted to our hospital because of edema of the lower legs, fever, and increasing fatigue. Laboratory evaluation revealed proteinuria, microhematuria, leukocytosis, thrombocytosis, anemia, a high level of C-reactive protein. A test for myeloperoxidase-antineutrophil cytoplasmic antibodies was highly positive. Microscopic polyarteritis nodosa was diagnosed and therapy with prednisolone was begun. Examination of a renal biopsy sample showed necrotizing crescentic glomerulonephritis. A chest roentgenogram and CT scan disclosed bilateral basilar interstitial changes. Six months later, the patient was admitted again because of disturbance of consciousness, malnutrition, and hyponatremia. After admission, alveolar infiltrates developed in the right lung and the patient died on the 5th hospital day as a result of respiratory failure. An autopsy revealed Candida pneumonia of the right lung and massive intra-alveolar hemorrhage, which was believed to have caused the respiratory failure. Other findings were usual interstitial pneumonia, cellular small-vessel angiitis in the lungs, and healed angiitis in the kidneys and liver. In this case of microscopic polyangiitis and chronic interstitial pneumonia, steroid therapy was effective against the angiitis, but the patient died of an opportunistic infection and alveolar hemorrhage.

Mycobacterium avium complex (MAC) is a common opportunistic infection in people with HIV. It causes fever, night sweats, weight loss, fatigue, diarrhea and abdominal pain, and the bacteria that causes it is found everywhere. Medicines can be given to strengthen the immune system and increase resistance to MAC. Patients need to consult with their doctors and follow their medical regimens to prevent MAC.
