Cervical human papillomavirus infection and shedding of human immunodeficiency virus in cervicovaginal fluids: a cross-sectional study.

We evaluated the association between human papillomavirus cervical infection and HIV shedding in cervicovaginal lavage fluid (CVL), studying 89 HIV-infected women recruited at the Department of Infectious Diseases of Brescia (Italy). HIV shedding in CVL was found in a similar proportion of women with (30%; 21/70) and without (31.6%; 6/19) cervical human papillomavirus infection. A statistically significant correlation was found between HIV viral load in serum and CVL among the 27 women with detectable HIV in CVL (r = 0.4; P = 0.04). However, women on highly active antiretroviral therapy were more likely to have detectable HIV-RNA in CVL despite negative viremia (80% vs. 8%; P < 0.005).

Differential diagnosis of cervical mycobacterial lymphadenitis in children.

BACKGROUND AND AIMS: The differential diagnosis between tuberculosis (TB) and lymphadenitis caused by nontuberculous mycobacteria (NTM) in children is often based on epidemiologic and clinical data. The aim of this study was to identify epidemiologic and clinical variables associated with TB lymphadenitis in children attending 2 TB out-patient clinics in northern Italy during a 10-year period. PATIENTS AND METHODS: All children less than 16 years of age attending the study sites suspected of mycobacterial disease from 1999 through 2008 were included in the analysis. Logistic regression was used to evaluate the variables independently associated with TB lymphadenitis. RESULTS: From 299 children diagnosed with mycobacterial disease 121 children (40%) had a clinical diagnosis of cervical mycobacterial lymphadenitis: 38 TB (31%) and 83 NTM lymphadenitis (69%) cases. Increasing age (OR, 1.29; 95% CI, 1.02-1.69; P = 0.04), being foreign born (OR, 11.60; 95% CI, 1.37-114.20; P = 0.02), and having an abnormal chest radiograph (OR, 18.32; 95% CI, 2.37-201.68; P = 0.008) were independently associated with TB lymphadenitis. In the selected model, a 5-year-old foreign born child with cervical lymphadenitis and abnormal findings on chest radiograph has an estimated 0.90 probability of having TB disease. On the other hand, an Italy born child of the same age with cervical lymphadenitis and normal chest radiograph has a 0.04 probability of having TB. CONCLUSION: Epidemiologic and clinical data are useful tools in the differential diagnosis between TB and NTM lymphadenitis when etiologic diagnosis is not available.

Forty meals for a drop of blood ...

Increasing migration flow to Western countries poses formidable challenges from the epidemiological, clinical, and cultural standpoints. A case of Dhat syndrome is presented in a young Pakistani male migrant living in Italy, which required integrated medical and cultural approach to be solved after a through diagnostic workout that did not yield any result.

Insulin resistance impairs rapid virologic response in HIV/hepatitis C virus coinfected patients on peginterferon-alfa-2a.

OBJECTIVES: To investigate the association between insulin resistance and rapid virologic response. DESIGN: All consecutive HIV/hepatitis C virus coinfected patients who started peg-interferon alpha-2a (180 microg/week) and ribavirin 1000-1200 mg/day were analysed. METHODS: Insulin resistance was defined according to the homeostasis model of assessment-insulin resistance calculated as fasting insulin (mIU/l) x fasting glucose (mmol/l)/22.5. Rapid virologic response was defined as testing negative for hepatitis C virus-RNA after 4 weeks of therapy. Fasting levels of insulin and glucose in plasma were measured in all patients on the first day of treatment. Hepatitis C virus-RNA was determined by quantitative PCR assay (version 3.0). Hepatitis C virus-RNA was measured by qualitative PCR assay (COBAS 2.0) after 4 weeks of treatment. RESULTS: Seventy-four HIV/hepatitis C virus coinfected patients were enrolled [mean age 41.7 years (SD 5.3), 61 men, 54.1% with advanced fibrosis (F3-4 according to METAVIR classification), 52.4% with infection by hepatitis C virus genotype 1 or 4]. Rapid virologic response was reached by 30 subjects. In the multivariate analysis the independent predictors of rapid virologic response were: genotype 1 or 4 [adjusted odds ratio 0.18 (0.06-0.55)], hepatitis C virus-RNA < 400.000 UI/ml [adjusted odds ratio 0.229 (0.09-0.92)] and homeostasis model of assessment-insulin resistance more than 3.00 [adjusted odds ratio 0.1 (0.05-0.6)]. CONCLUSION: The homeostasis model of assessment-insulin resistance score should be evaluated and possibly corrected before starting anti-hepatitis C virus therapy.
