ABSTRACT

We identified demographic, clinical and biological determinants of herpes simplex virus type 2 (HSV-2) shedding among HIV-infected participants in the Women's HIV Interagency Study (WIHS). Cervicovaginal lavage (CVL) specimens from 369 HIV-infected HSV seropositive women were tested with TaqMan polymerase chain reaction (PRC) for detection HSV-2 DNA. Seven percent of women tested positive for HSV-2 DNA in CVL. Significant correlates of the presence of HSV-2 DNA in CVL were being younger, African American or Hispanic race/ethnicity and injecting drugs in the past six months (P < 0.05). A borderline significant trend for reduced viral shedding with higher CD4+ T cell counts was observed (P = 0.08). All women who were never observed with any genital lesions and had consistently negative self-reported history of genital sores throughout the follow-up (n = 29, 8%) were negative for CVL HSV-2 DNA. HSV-2 DNA quantity was significantly associated with having frequent subsequent lesion recurrences (Spearman rho = 0.48, P = 0.016; adjusted prevalence ratio [APR] = 2.5, P = 0.012). Increasing the age of the host was inversely correlated with decreased viral shedding over time. However, a subset of older women continued to shed significant amounts of virus despite passage of time. This study provides genital HSV-2 DNA titre as a quantitative and symptom- and sign-based measures as qualitative predictors of HSV-2 shedding from the lower genital tract among HIV-infected women.

ABSTRACT

Human immunodeficiency virus type 1 (HIV-1) RNA measurements were evaluated within an externally controlled multilaboratory program. Three external standards (1.5 x 10(3) to 1.5 x 10(6) copies/ml) were included in 814 assay runs by four laboratories. Results indicate that HIV-1 RNA levels can be measured with a precision equal to that of the pre-highly active antiretroviral therapy era (standard deviations, +/-0.16 to 0.25 log10 units).

ABSTRACT

Solitary rectal ulcer syndrome (SRUS) is a rarely reported condition in children. The typical presentation is one of anorectal pain with passage of blood and mucus per rectum in the setting of defecation abnormalities. Diagnosis is made via endoscopy and biopsy. Solitary rectal ulcer syndrome alone is usually a benign condition; however, significant morbidity can occur if complicated by underlying disease states. We report an adolescent with hemophilia A and SRUS who presented with a rectal bleed that required blood transfusion.

ABSTRACT

OBJECTIVES: Chicken skin mucosa is a newly described endoscopic finding associated with colonic neoplasms in adults. Chicken skin mucosa was sought in children with juvenile polyps to determine the prevalence, endoscopic features, and location. An alternative theory is proposed for the pathogenic mechanism of this finding. METHODS: Children having colonoscopy and polypectomy were prospectively evaluated for the presence of chicken skin mucosa. The location of the polyps was determined at colonoscopy; the size of removed polyps was measured during processing of samples in pathology. Biopsies from colonic chicken skin mucosa were stained with hematoxylin and eosin and mucicarmine. RESULTS: Over a 1-yr period, 27 juvenile polyps were removed from 15 children at colonoscopy. Eleven of 15 children (73%) were found to have polyps with chicken skin mucosa; overall, 43% of the polyps had associated chicken skin mucosa. Chicken skin mucosa-positive polyps were larger than chicken skin mucosa-negative polyps and were only found in the rectosigmoid colon. Lipid-laden macrophages were found in all samples of chicken skin mucosa tested. CONCLUSIONS: Chicken skin mucosa is a common finding in children with juvenile polyps. It probably is the result of local mucosal trauma, rather than a preneoplastic lesion.
