Human immunodeficiency virus (HIV) infection is a risk factor for both human papillomavirus infection (HPV) and cervical squamous intraepithelial lesions (SIL). This study was undertaken to determine the prevalence of underlying SIL among women with a cytological diagnosis of HPV infection alone. Of 160 women, the overall prevalence of HIV infection and SIL was 41.9% and 36.9%, respectively. Biopsy which confirmed SIL of any grade was demonstrated in 49.3% and 28% of HIV-infected and HIV-non-infected women. However, for individual grade of SIL, there was no statistical significant difference among the HIV-infected and HIV-non-infected groups. Although the finding of a cytological diagnosis of HPV among HIV-non-infected women is usually managed conservatively, the finding of a high rate of underlying SIL among HIV-infected women may argue against such a conservative approach.

Parenteral glutamine supplementation in acute inflammatory conditions is controversial. We evaluated the inflammatory and survival responses after parenteral glutamine infusion in sodium taurocholate-induced acute pancreatitis (AP) model. Lewis rats received 1 g/kg parenteral glutamine (n = 42), saline (n = 44), or no treatment (n = 45) for 48 h before AP induction. Blood, lung, and liver samples were collected 2, 12, and 24 h after AP to measure serum cytokines levels and tissue heat shock protein (HSP) expression. From each group, 20 animals were not sacrificed after AP for a 7-day mortality study. Serum cytokine levels did not differ among groups at any time point, but the intragroup analysis over time showed higher interferon-γ only in the nontreatment and saline groups at 2 h (versus 12 and 24 h; both p ≤ 0.05). The glutamine group exhibited greater lung and liver HSP90 expression than did the nontreatment group at 2 and 12 h, respectively; greater liver HSP90 and HSP70 expression than did the saline group at 12 h; and smaller lung HSP70 and liver HSP90 expression than did the nontreatment group at 24 h (all p ≤ 0.019). The 7-day mortality rate did not differ among groups. In experimental AP, pretreatment with parenteral glutamine was safe and improved early inflammatory mediator profiles without affecting mortality.
