Clin Infect Dis 2004;38:
Slide #6 DH Spach, MD. Presented at IAS–USA/RWCA Clinical Conference, June Hepatitis A & B Vaccination Practices for Ambulatory Patients with HIV-Infection Conclusions “Although there were low rates of complete hepatitis vaccination in this cohort of ambulatory patients, prompt efforts to vaccinate patients entering care, receipt of antiretroviral therapy, and practice reminder systems may enhance vaccination practices.” DHS/HIV/PP From: Tedalid EM et al.

Slide #11 DH Spach, MD. Presented at IAS–USA/RWCA Clinical Conference, June Isolated HBcAb in HIV-Infected Persons Conclusions “After hepatitis B vaccination, the anamnestic response rate in HIV-1–positive subjects who tested positive for isolated anti-HBc but negative for anti-HBe was low and was comparable to that in subjects who tested negative for anti-HBc.” “This finding suggests that testing for anti-HBc alone may not be a reliable assessment of protection from HBV infection.” DHS/HIV/PP From: Gandi RT, et al.

Slide #28 DH Spach, MD. Presented at IAS–USA/RWCA Clinical Conference, June DHS/HIV/PP Medication-Related Adverse Effects Case Studies
Slide #29 DH Spach, MD. Presented at IAS–USA/RWCA Clinical Conference, June Case History A 38-year-old HIV-infected man with a CD4 count of 188 cells/mm 3 starts on a regimen of tenofovir plus lamivudine plus lopinavir-ritonavir. Other medications include inhaled fluticasone, montelukast, and trimethoprim-sulfamethoxazole. Three months later his HIV RNA is < 50 copies/ml, but at the 3- month visit, he complains of new weakness in his upper arms and legs as well as puffy cheeks. He also has new onset hypertension and hyperglycemia. What do you think is the most likely cause of his new problems? 1. Rapid onset protease inhibitor-related lipodystrophy 2. Iatrogenic Cushing’s syndrome from fluticasone 3. Renal toxicity caused by tenofovir 4. Lopinavir-ritonavir hepatotoxicity DHS/HIV/PP
Slide #30 DH Spach, MD. Presented at IAS–USA/RWCA Clinical Conference, June Case History A 43-year-old HIV-infected woman with a CD4 count of 374 cells/mm 3 is admitted to the hospital with a severe buttock MRSA abscess. The patient is discharged on a 7-day course of linezolid. Two days after leaving the hospital, the patient comes to the clinic with mental status changes, increased muscle tone, tremor, and diarrhea. Examination shows T = 38.5°, agitation, hyperreflexia, and clonus. Medications (Chronic) - Abacavir-lamivudine - Atazanavir - Citalopram - Methadone What do you think would best explain the clinical course in this patient? 1. Linezolid-induced opiate withdrawal (decrease in methadone level) 2. Abacavir hypersensitivity syndrome 3. Serotonin syndrome 4. Malignant hyperthermia DHS/HIV/PP
Slide #31 DH Spach, MD. Presented at IAS–USA/RWCA Clinical Conference, June DHS/ HIV/PP Case History A 29-year-old man has a CD4 count of 41 and an HIV RNA of 134,000 and is admitted to the hospital with moderately severe PCP (pO2 = 73). He has a history of Stevens-Johnson syndrome from TMP/SMX; he receives IV pentamidine 4 mg/kg/d. He is on no ARV therapy. On the 6th day after admission, the patient’s respiratory status has improved, but he complains of sudden onset of headache and blurred vision. The nurse notes he is acutely confused and minimally responsive. You are immediately called. What is likely to be the most effective diagnostic measure you could take? 1. Emergent contrast brain CT scan 2. Stat cryptococcal antigen 3. Finger stick for glucose level 4. Stat sodium level
