HIV/AIDS

Presentation:
H.U., a 57 year old male, presents to the emergency room alone with a persistent and productive cough lasting over three weeks, sore throat, oral ulcers, weakness, fever and report of consistent weight loss over past two years. The patient comes from rural Montana, has not received any medical care since being hospitalized after a car crash in 1982 (ruptured spleen and multiple fractured ribs, for which he received 2 units of PRBCs and has never visited a dentist. He reports that he had to leave his job as a landscaper 2 years ago because of his constant fatigue, and reports that the oral ulcers cause him pain when he eats. He is pale, diaphoretic and emaciated.

Differential Diagnoses:
    Infection (systemic, respiratory, or GI)
    Tuberculosis
    Cancer
    HIV infection

Diagnosis & prognosis:
A focused health history reveals that H.U. has experienced 6 episodes of suspected undiagnosed pneumonia since 1983 and has been “sick for as long as he can remember.” The physical assessment reveals multiple open, painful ulcers in the mouth, swollen lymph nodes, bilateral weakness of all extremities, severe cachexia, and small round, bluish-red lumps the size of peas all over the inner and anterior thighs. Blood is drawn, urine and stool samples are taken, and wound cultures are collected from the oral ulcers. Blood tests reveal H.U. is positive for HIV, and his CD4 count is 7 cells per microliter, well below the cut-off for AIDS (200 cells per microliter). The lumps on his thighs are determined to be Kaposi’s sarcoma, a cancerous tumor of the connective tissue commonly affecting persons with weakened immune systems. A sputum culture reveals TB and a chest X-ray shows extensive damage to the lung tissue, over 75%. It is speculated that H.U. acquired HIV through his blood transfusions in 1982, three years before HIV antibody testing methods became available to screen donor blood for the virus. Unfortunately, since H.U.’s CD4 count is so low and his therapy will be started so late, he does not have a good prognosis. Current guidelines suggest beginning treatment for HIV when a patient’s CD4 count is 350 or lower, though other studies support initiating treatment earlier. It has been found that late diagnoses are responsible for three quarters of AIDS deaths. Since H.U. will be starting treatment with a CD4 count of only 7 and almost 30 years of infection, it is unlikely that his immune system will ever recover. He will most likely die from one of the opportunistic infections he currently has.

Treatment: – the following treatments were offered to the patient

Outcome:
Having been told about his diagnosis and prognosis, H.U. chooses to try everything possible on the treatment list. However, after 3 weeks his CD4 count has dropped to 5, and his condition worsens. He surrenders all treatment except for the pain medication and palliative care, and 23 days after his admittance he chooses to return home, where he lives alone. He will be visited daily by a palliative care nurse who will help him with his pain medications and ADLs. H.U. is terminally ill, so the palliative care nurse will make him as comfortable as possible and help him prepare for a peaceful death.
