Case Statement == A 23-year-old G1P0 at 26 weeks and 3 days gestation presented to the Emergency Department (ED) at a private hospital (henceforth referred to as hospital no. with adding HIV RNA screening at time of standard anti-HIV Elisa screening Letaxaban (TAK-442) test in pregnancy. Novel laboratory methods including pooling of sera for HIV RNA could reduce the cost of HIV RNA screening. == 1. Case Statement == A 23-year-old G1P0 at 26 weeks and 3 days gestation presented to the Emergency Department (ED) at a private hospital (henceforth referred to as hospital no. 1) complaining of a headache. Her past medical history was significant for chronic hypertension, depressive disorder, stress, and uterine fibroids. Her obstetric course had been complicated by intermittent bouts of abdominal pain since 4 weeks of gestation, for which she underwent a diagnostic laparoscopy significant only for a ruptured corpus luteum. She had been a patient of our teaching institution since early first trimester, at which time all prenatal labs were performed. The only pertinent findings were Rh-negative status and Trichomonas vaginalis infection. HIV Elisa test was negative. At approximately 20 weeks gestational age, the patient transferred her care from the teaching institution to a community physician. All prenatal labs were again repeated; other than an abnormal pap smear, all labs including HIV antibody test were negative. Social history obtained upon admission revealed her current partner, and father of the baby, was a 50-year-old man with a history of incarceration, residence in shelters for Letaxaban (TAK-442) the homeless, and prior hospitalizations for respiratory infection that was suspicious for tuberculosis. Initial workup of the mother in the ED at hospital no. 1 revealed elevated liver enzymes in the range of 400500’s, leukopenia, and maternal fever. HIV Elisa was negative and HIV RNA viral load was ordered. The patient was admitted to the hospital. To evaluate the patients’ headache, neurology and infectious disease consults were requested and a lumbar puncture was performed. VDRL and Cryptosporidium Letaxaban (TAK-442) test were ordered and were negative. The working diagnosis at this time was disseminated infection with Herpes simplex virus (HSV). The infectious disease physician recommended intravenous acyclovir for 10 days. On antiviral therapy day number five, the patient requested transfer to another private hospital (henceforth identified as hospital no. 2) where her obstetrician had admitting privileges. Of note, HIV viral load was still pending at time of transfer. Upon arrival at hospital no. 2, a Maternal-Fetal medicine specialist from our teaching institution was consulted to evaluate the presumed disseminated HSV infection. Social history in the transferring note received from hospital no. 1 stated that the patient’s partner was currently hospitalized with renal failure and end-stage AIDS. The plan at this time was to continue intravenous Acyclovir for the presumed disseminated HSV infection while HIV workup was in progress. Repeating HIV rapid screen test, HIV RNA viral load, and CD4 and CD8 counts were done, a PPD test was placed, and workup was ordered for elevated liver enzymes. Consultations with infectious disease and hepatology were requested. WBC on admission to hospital no. 2 was 4.3; Hepatitis A, B, C serologies, Human Granulocytic Ehrlichiosis IgG and IgM, and Toxoplasmosis IgG and IGM were negative. A right upper quadrant ultrasound was performed and ruled out any pathology. The PPD was read as negative. Blood cultures were negative. Rapid screen HIV test was again negative. Several days after admission to hospital no. 2, laboratory results were received from hospital no. 1, which were significant for HIV viral load being greater than 500,000 copies/mL and CD4 count of Mouse monoclonal to CD15.DW3 reacts with CD15 (3-FAL ), a 220 kDa carbohydrate structure, also called X-hapten. CD15 is expressed on greater than 95% of granulocytes including neutrophils and eosinophils and to a varying degree on monodytes, but not on lymphocytes or basophils. CD15 antigen is important for direct carbohydrate-carbohydrate interaction and plays a role in mediating phagocytosis, bactericidal activity and chemotaxis 227 cell/mm3. Thus the patient received the new diagnosis of acute HIV infection. She was started on an antiretroviral regimen of Combivir 150 mg/300 mg 1 tablet twice daily and Viracept 625 mg 2 tablets twice daily. On hospital day 6, her liver function tests decreased to an AST of 191, ALT of 365, and an alkaline phosphatase of 111. HIV RNA viral load that was obtained on admission to hospital no. 2 returned as 434,000 copies/mL. CD4 count was 323.9 cell/mm3. Her symptoms of fever and headache resolved and she was later discharged home without further complications or findings. Of note, laboratory studies as an outpatient at approximately 3 weeks later demonstrated.
