Country differences and determinants of yield in programmatic migrant TB screening in four European countries.

INTRODUCTION The WHO End TB Strategy emphasises early diagnosis and screening of TB in high-risk groups, including migrants. We analysed TB yield data from four large migrant TB screening programmes to inform TB policy.METHODS We pooled routinely collected individual TB screening episode data from Italy, the Netherlands, Sweden and the United Kingdom under the European Union Commission E-DETECT.TB grant, described characteristics of the screened population, and analysed TB case yield.RESULTS We collected data on 2,302,260 screening episodes among 2,107,016 migrants, mostly young adults aged 18-44 years (77.8%) from Asia (78%) and Africa (18%). There were 1,658 TB cases detected through screening, with substantial yield variation (per 100,000): 201.1 for Sweden (95% confidence intervals CI 111.4-362.7), 68.9 (95% CI 65.4-72.7) for the United Kingdom, 83.2 (95% CI 73.3-94.4) for the Netherlands and 653.6 (95% CI 445.4-958.2) in Italy. Most TB cases were notified among migrants from Asia (n = 1,206, 75/100,000) or Africa (n = 370, 76.4/100,000), and among asylum seekers (n = 174, 131.5/100,000), migrants to the Netherlands (n = 101, 61.9/100,000) and settlement visa migrants to the United Kingdom (n = 590, 120.3/100,000).CONCLUSIONS We found considerable variations in yield across programmes, types of migrants and country of origin. These variations may be partly explained by differences in migration patterns and programmatic characteristics

Drivers determining TB disease screening yield in four European screening programmes: a comparative analysis.

INTRODUCTION: The WHO End-TB Strategy emphasises screening for early diagnosis of tuberculosis (TB) in high-risk groups, including migrants. We analysed key drivers of TB yield differences in four large migrant TB screening programmes to inform TB control planning and feasibility of a European approach. METHODS: We pooled individual TB screening episode data from Italy, the Netherlands, Sweden, and the UK and analysed predictors and interactions for TB case yield using multivariable logistic regression models. RESULTS: Between 2005-2018 in 2,302,260 screening episodes among 2,107,016 migrants to four countries; the programmes identified 1,658 TB cases (yield 72.0 per 100,000; 95% confidence interval, CI68.6-75.6). In logistic regression analysis, we found associations between TB screening yield and age (>55 years odds ratio, OR2.91, CI2.24-3.78), being an asylum seeker (OR3.19, CI1.03-9.83) or on a settlement visa (OR1.78, CI1.57-2.01), close TB contact (OR12.25, 11.73-12.79), and higher TB incidence in the country of origin (CoO). We demonstrated interactions between migrant typology and age, as well as CoO. For asylum seekers, the elevated TB risk remained similar above CoO incidence thresholds of 100 per 100,000. CONCLUSIONS: Key determinants of TB yield included close contact, increasing age, incidence in CoO and specific migrant groups including asylum seekers and refugees. For most migrants such as UK students and workers, TB yield significantly increased with levels of incidence in CoO. The high, CoO-independent TB risk in asylum seekers above a 100 per 100,000 threshold could reflect higher transmission and reactivation risk of migration routes; with implications for selecting populations for TB screening

An epidemiological survey of vulvovaginal candidiasis in Italy

Eight Italian hospital or University gynecology clinics participated in a prospective survey of patients with culture-confirmed symptomatic vulvovaginal candidiasis (VVC) (October 1999 to March 2001). Of 1138 patients recruited in the study, 931 were evaluable. A recent history of VVC was documented in 43.5% patients (358/823) with a mean number of 2.9 +/- 2.7 episodes per patient (N = 302). A total of 77 patients (10.0%) had a history of recurrent VVC (four and more episodes in a 12-month period). The most frequent associated factors were related to life style: synthetic fabric underwear, vaginal douching and bike, training bike and motorbike (about 1/3 each). Oral contraception was found in 20.8% patients, recent antibiotic use in 15.9% patients, current pregnancy concemed 10.3% patients while 3.4% patients were taking hormonal replacement therapy. Diabetes, corticosteroids or HIV were rarely encountered. Yeast was documented by direct microscopy in 78.3% patients (448/572). A positive culture was obtained in 98.3% patients (909/925). Candida albicans was the predominant species (77.1%), followed by Candida glabrata (14.6%) and Candida krusei (4.0%). With the exception of one center with a lower proportion of C albicans, this latter represented between 75 and 85% of the isolates. Overall, this study confirmed the preponderant role played by C. albicans in either sporadic and recurrent VVC. (C) 2003 Elsevier Science Ireland Ltd. All rights reserved
