Abstract
Objective We assessed experience and preferences among term women undergoing induction of labor with oral misoprostol or Foley catheter. Study Design In 18 of the 29 participating hospitals in the PROBAAT-II trial, women were asked to complete a questionnaire within 24 hours after delivery. We adapted a validated questionnaire about expectancy and experience of labor and asked women whether they would prefer the same method again in a future pregnancy. Results The questionnaire was completed by 502 (72%) of 695 eligible women; 273 (54%) had been randomly allocated to oral misoprostol and 229 (46%) to Foley catheter. Experience of the duration of labor, pain during labor, general satisfaction with labor, and feelings of control and fear related to their expectation were comparable between both the groups. In the oral misoprostol group, 6% of the women would prefer the other method if induction is necessary in future pregnancy, versus 12% in the Foley catheter group (risk ratio: 0.70; 95% confidence interval: 0.55-0.90; p = 0.02). Conclusion Women's experiences of labor after induction with oral misoprostol or Foley catheter are comparable. However, women in the Foley catheter group prefer more often to choose a different method for future inductions.

The cost effectiveness of a tailored, web-based care program to enhance postoperative recovery in gynecologic patients in comparison with usual care: protocol of a stepped wedge cluster randomized controlled trial. JMIR Res Protoc 2014; 3:e30. [PMID: 24943277 PMCID: PMC4090379 DOI: 10.2196/resprot.3236] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2014] [Accepted: 05/21/2014] [Indexed: 11/13/2022] Open
Abstract
Background The length of recovery after benign gynecological surgery and return to work frequently exceeds the period that is recommended or expected by specialists. A prolonged recovery is associated with a poorer quality of life. In addition, costs due to prolonged sick leave following gynecological surgery cause a significant financial burden on society. Objective The objective of our study was to present the protocol of a stepped wedge cluster randomized controlled trial to evaluate the cost effectiveness of a new care program for patients undergoing hysterectomy and/or adnexal surgery for benign disease, compared to the usual care. Methods The care program under study, designed to improve convalescence and to prevent delayed return to work, targets two levels. At the hospital level, guidelines will be distributed among clinical staff in order to stimulate evidence-based patient education. At the patient level, additional perioperative guidance is provided by means of an eHealth intervention, equipping patients with tailored convalescence advice, and an occupational intervention is available for those patients at risk of prolonged sick leave. Due to the stepped wedge design of the trial, the care program will be sequentially rolled out among the 9 participating hospitals, from which the patients are recruited. Eligible for this study are employed women, 18-65 years of age, who are scheduled for hysterectomy and/or laparoscopic adnexal surgery. The primary outcome is full sustainable return to work. The secondary outcomes include general recovery, quality of life, self-efficacy, coping, and pain. The data will be collected by means of self-reported electronic questionnaires before surgery and at 2, 6, 12, 26, and 52 weeks after surgery. Sick leave and cost data are measured by monthly sick leave calendars, and cost diaries during the 12 month follow-up period. The economic evaluation will be performed from the societal perspective. All statistical analyses will be conducted according to the intention-to-treat principle. Results The enrollment of the patients started October 2011. The follow-up period will be completed in August 2014. Data cleaning or analysis has not begun as of this article’s submission. Conclusions We hypothesize the care program to be effective by means of improving convalescence and reducing costs associated with productivity losses following gynecological surgery. The results of this study will enable health care policy makers to decide about future implementation of this care program on a broad scale.

Abstract
BACKGROUND Physiotherapy involving pelvic-floor muscle training is advocated as first-line treatment for stress urinary incontinence; midurethral-sling surgery is generally recommended when physiotherapy is unsuccessful. Data are lacking from randomized trials comparing these two options as initial therapy. METHODS We performed a multicenter, randomized trial to compare physiotherapy and midurethral-sling surgery in women with stress urinary incontinence. Crossover between groups was allowed. The primary outcome was subjective improvement, measured by means of the Patient Global Impression of Improvement at 12 months. RESULTS We randomly assigned 230 women to the surgery group and 230 women to the physiotherapy group. A total of 49.0% of women in the physiotherapy group and 11.2% of women in the surgery group crossed over to the alternative treatment. In an intention-to-treat analysis, subjective improvement was reported by 90.8% of women in the surgery group and 64.4% of women in the physiotherapy group (absolute difference, 26.4 percentage points; 95% confidence interval [CI], 18.1 to 34.5). The rates of subjective cure were 85.2% in the surgery group and 53.4% in the physiotherapy group (absolute difference, 31.8 percentage points; 95% CI, 22.6 to 40.3); rates of objective cure were 76.5% and 58.8%, respectively (absolute difference, 17.8 percentage points; 95% CI, 7.9 to 27.3). A post hoc per-protocol analysis showed that women who crossed over to the surgery group had outcomes similar to those of women initially assigned to surgery and that both these groups had outcomes superior to those of women who did not cross over to surgery. CONCLUSIONS For women with stress urinary incontinence, initial midurethral-sling surgery, as compared with initial physiotherapy, results in higher rates of subjective improvement and subjective and objective cure at 1 year.

Abstract
STUDY QUESTION What is the treatment success rate of systemic methotrexate (MTX) compared with expectant management in women with an ectopic pregnancy or a pregnancy of unknown location (PUL) with low and plateauing serum hCG concentrations? SUMMARY ANSWER In women with an ectopic pregnancy or a PUL and low and plateauing serum hCG concentrations, expectant management is an alternative to medical treatment with single-dose systemic MTX. WHAT IS KNOWN AND WHAT THIS PAPER ADDS MTX is often used in asymptomatic women with an ectopic pregnancy or a PUL with low and plateauing serum hCG concentrations. These pregnancies may be self-limiting and watchful waiting is suggested as an alternative, but evidence from RCTs is lacking. The results of this RCT show that expectant management is an alternative to treatment with systemic MTX in a single-dose regimen in these women. STUDY DESIGN, SIZE, DURATION A multicentre RCT women were assigned to systemic MTX (single dose) treatment or expectant management, using a web-based randomization program, block randomization with stratification for hospital and serum hCG concentration (<1000 versus 1000-2000 IU/l). The primary outcome measure was an uneventful decline of serum hCG to an undetectable level (<2 IU/l) by the initial intervention strategy. Secondary outcome measures included additional treatment, side effects and serum hCG clearance time. PARTICIPANTS, SETTING, METHODS From April 2007 to January 2012, we performed a multicentre study in The Netherlands. All haemodynamically stable women >18 years old with both an ectopic pregnancy visible on transvaginal sonography and a plateauing serum hCG concentration <1500 IU/l or with a PUL and a plateauing serum hCG concentration <2000 IU/l were eligible for the trial. MAIN RESULTS We included 73 women of whom 41 were allocated to single-dose MTX and 32 to expectant management. There was no difference in primary treatment success rate of single-dose MTX versus expectant management, 31/41 (76%) and 19/32 (59%), respectively [relative risk (RR) 1.3 95% confidence interval (CI) 0.9-1.8]. In nine women (22%), additional MTX injections were needed, compared with nine women (28%) in whom systemic MTX was administered after initial expectant management (RR 0.8; 95% CI 0.4-1.7). One woman (2%) from the MTX group underwent surgery compared with four women (13%) in the expectant management group (RR 0.2; 95% CI 0.02-1.7), all after experiencing abdominal pain within the first week of follow-up. In the MTX group, nine women reported side effects versus none in the expectant management group. No serious adverse events were reported. Single-dose systemic MTX does not have a larger treatment effect compared with expectant management in women with an ectopic pregnancy or a PUL and low and plateauing serum hCG concentrations. WIDER IMPLICATIONS OF THE FINDINGS Sixty percent of women after expectant management had an uneventful clinical course with steadily declining serum hCG levels without any intervention, which means that MTX, a potentially harmful drug, can be withheld in these women. BIAS, LIMITATION AND GENERALISABILITY: A limitation of this RCT is that it was an open (not placebo controlled) trial. Nevertheless, introduction of bias was probably limited by the strict criteria to be fulfilled for treatment with MTX.

The METEX study: methotrexate versus expectant management in women with ectopic pregnancy: a randomised controlled trial. BMC Womens Health 2008; 8:10. [PMID: 18565217 PMCID: PMC2453103 DOI: 10.1186/1472-6874-8-10] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2008] [Accepted: 06/19/2008] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Patients with ectopic pregnancy (EP) and low serum hCG concentrations and women with a pregnancy of unknown location (PUL) and plateauing serum hCG levels are commonly treated with systemic methotrexate (MTX). However, there is no evidence that treatment in these particular subgroups of women is necessary as many of these early EPs may resolve spontaneously. The aim of this study is whether expectant management in women with EP or PUL and with low but plateauing serum hCG concentrations is an alternative to MTX treatment in terms of treatment success, future pregnancy, health related quality of life and costs. METHODS/DESIGN A multicentre randomised controlled trial in The Netherlands. Hemodynamically stable patients with an EP visible on transvaginal ultrasound and a plateauing serum hCG concentration < 1,500 IU/L or with a persisting PUL with plateauing serum hCG concentrations < 2,000 IU/L are eligible for the trial. Patients with a viable EP, signs of tubal rupture/abdominal bleeding, or a contra-indication for MTX will not be included. Expectant management is compared with systemic MTX in a single dose intramuscular regimen (1 mg/kg) in an outpatient setting. Serum hCG levels are monitored weekly; in case of inadequately declining, systemic MTX is installed or continued. In case of hemodynamic instability and/or signs of tubal rupture, surgery is performed. The primary outcome measure is an uneventful decline of serum hCG to an undetectable level by the initial intervention. Secondary outcomes are (re)interventions (additional systemic MTX injections and/or surgery), treatment complications, health related quality of life, financial costs, and future fertility. Analysis is performed according to the intention to treat principle. Quality of life is assessed by questionnaires before and at three time points after randomisation. Costs are expressed as direct costs with data on costs and used resources in the participating centres. Fertility is assessed by questionnaires after 6, 12, 18 and 24 months. Patients' preferences will be assessed using a discrete choice experiment. DISCUSSION This trial will provide guidance on the present management dilemmas in women with EPs and PULs with low and plateauing serum hCG concentrations.

Abstract
OBJECTIVES (1) To describe the epidemiology of neonatal group B streptococcal (GBS) disease over five years (1997-2001) in the Netherlands, stratified for proven and probable sepsis and for very early (<12 h), late early (12 h - <7 days) and late (7-90 days) onset sepsis. (2) To evaluate the effect of the introduction in January 1999 of guidelines for prevention of early onset GBS disease based on risk factors. METHODS Data on cases were collected in collaboration with the Dutch Paediatric Surveillance Unit and corrected for under-reporting by the capture-recapture technique. RESULTS Total incidence of proven very early onset, late early onset and late onset GBS sepsis was 0.32, 0.11 and 0.14 per 1000 live births, respectively, and of probable very early onset, late early onset and late onset GBS sepsis was 1.10, 0.18 and 0.02 per 1000 live births, respectively. Maternal risk factors were absent in 46% of the proven early onset cases. Considerably more infants with proven GBS sepsis were boys. 64% of the infants with proven very early onset GBS sepsis were first born compared with 47% in the general population. After the introduction of guidelines the incidence of proven early onset sepsis decreased considerably from 0.54 per 1000 live births in 1997-8 to 0.36 per 1000 live births in 1999-2001. However, there was no decrease in the incidence of meningitis and the case fatality rate in the first week of life. The incidence of late onset sepsis also remained unchanged. CONCLUSION After the introduction prevention guidelines based on risk factors there has been a limited decrease in the incidence of proven early onset GBS sepsis in the Netherlands. This study therefore recommends changing the Dutch GBS prevention guidelines.

Abstract
The Dutch College of General Practitioners (NHG) revised their practice guideline on vaginal discharge. From a gynaecological point of view, relocation of cervix problems from this guideline to the NHG guideline 'The STD consultation' is not practical. Moreover, the role of simple, but effective diagnosis with a microscope in the primary-care setting cannot be overemphasized. The reluctance to oral treatment is rather inopportune, because once-only ingestion has the advantage of promoting compliance. As physical examination is not always necessary in a recurrent Candida infection, treatment performed by the patient with imidazole compounds is a possibility that does not always result in abuse or increased resistance.

Abstract
We sent a questionnaire to all members of the European Society for Paediatric Infectious Diseases and to all delegates of the European Association of Perinatal Medicine to determine existing policies for prevention of neonatal group B streptococcal (GBS) infection in Europe. The incidence of GBS colonization in pregnant women and of neonatal GBS infection varies. Policies for prevention of GBS infection are not well-developed.

Abstract
Group B streptococcal (GBS) infection is still an important cause of morbidity and mortality in newborn infants. In The Netherlands, there are no published data on the incidence of neonatal GBS infection. We collected data of all infants with GBS disease during the first 3 months of life, as reported to the Dutch Paediatric Surveillance Unit (DPSU) during a period of 2 years (1997-98). Neonates with early-onset GBS disease (both sepsis and probable sepsis) were included for further analysis. The level of completeness of the DPSU data was determined by capture-recapture techniques. The incidence of early-onset GBS disease in The Netherlands in 1997-98, as calculated from the DPSU data, was 0.9 per 1000 live births. After correction for under-reporting, the incidence was estimated to be 1.9 per 1000 live births. The case fatality rate of early-onset GBS disease was only 5%. Despite the decrease in the mortality rate during the last decades, it remains a serious condition with potential irreversible brain damage. Therefore, formal guidelines for the prevention of neonatal early-onset GBS disease in The Netherlands were introduced in 1999. The data collected in this study may serve as baseline data for evaluation of the effect of these guidelines.

Abstract
UNLABELLED The prevalence of human papillomavirus (HPV) rises with increasing histological severity of neoplasia, more cigarettes smoked per day and higher lifetime number of sexual partners in women with cervical dyskaryosis. Recently, the highly sensitive SPF10 primers and Inno-LiPA (line probe assay) HPV prototype research assay became available for the detection and typing of HPV. BACKGROUND using this system, we challenged the previously reported findings. STUDY DESIGN the study group comprised 304 women referred because of abnormal pap smears in whom a histological diagnosis was made. Data on the lifetime number of sexual partners and smoking behaviour were obtained by questionnaire. HPV analysis was performed on cervical scrapes obtained at the enrollment visit. RESULTS oncogenic HPV was found in 288 (95%) women. A total of 86 (30%) out of these 288 women disclosed multiple types. HPV 16 occurred significantly less often in multiple infections than was expected on the basis of chance alone. The grade of neoplasia was significantly associated with the presence of oncogenic HPV, and this association depended on the presence of HPV type 16. No association was found between grade of neoplasia and the presence of multiple HPV types. Neither the lifetime number of sexual partners nor smoking were associated with oncogenic HPV, the five most frequent HPV types separately or the presence of multiple types. CONCLUSION we conclude that the association between the detection of HPV and the epidemiological risk factors, as found with the GP5/6 PCR in the past, could not be confirmed when using SPF10 PCR primers and LiPA HPV genotyping. We suggest that the number of sexual partners and smoking may be determinants of high HPV viral load rather than determinants of the presence of HPV per se.

Abstract
OBJECTIVE To explore whether the presence of Chlamydia trachomatis antibodies is associated with the severity of neoplastic lesions in women with cervical dyskaryosis. METHODS In a cross sectional study in two groups of women referred for an abnormal Papanicolaou smear (group A: 296, group B: 331 women) blood samples were analysed for antichlamydial antibodies by enzyme immunoassay. Cervical neoplasia was graded histologically. RESULTS In group A no association was found between increasing grade of CIN and the presence of antichlamydial antibodies. The proportion (93%) of women with antichlamydial antibodies was higher in 14 women with (micro)invasive carcinoma than in women with CIN (35%). As the high prevalence of antichlamydial antibodies in women with cervical carcinoma is not consistent with prevalences reported in recent literature, we analysed a second group of women in which indeed the high prevalence was not confirmed CONCLUSION Our results suggest that the presence of circulating antichlamydial antibodies is not associated with the severity of neoplastic lesions and it seems unlikely that C trachomatis has a role in the progression of cervical neoplasia.

Abstract
Groups A and B streptococci are of great significance in the history of obstetrics. Group A streptococci were a great threat to the puerperium, especially in the 19th century, when homebirth was replaced by institutional birth in lying-in hospitals. The history of the rise and fall of puerperal fever is indeed a tragedy. Some people, like Semmelweis, who brought new and important evidence based findings were not believed by their fellow obstetricians, an attitude that spoiled thousands of innocent lives. Even today group A streptococci, though seldom, may be the cause of puerperal sepsis. Group B streptococci are widespread and may cause sepsis and important lifelong morbidity or mortality of the newborn. Obstetricians today try to establish cost-effective prophylactic measures during labor to prevent these neonatal infections.

Abstract
OBJECTIVE Comparison of the incidence and case fatality of early-onset group B streptococcus sepsis and sepsis caused by other pathogens in neonates after change of management of intrauterine infection. METHODS All infants delivered from 1988 through 1997 at a gestational age > or = 24 weeks with a birth weight > or = 500 gram without lethal congenital abnormalities were eligible for inclusion. Infants delivered by cesarean section before the onset of labor or rupture of membranes were excluded. During the first period (1988-1991) intrauterine infection was diagnosed by a temperature > 38 degrees C, during the second period (1992-1997) this diagnosis was made at a lower temperature (> or = 37.8 degrees C) or by fetal tachycardia > or = 160/min. Treatment of intrauterine infection was similar during both periods with 3 x 2 gram amoxicillin and 1 x 240 mg gentamicin every 24 hours intravenously during labor. Prophylactic treatment during labor was only given to women with a history of an earlier infant with early-onset group B streptococcus sepsis. RESULTS During the first period 6,103 infants were included, during the second period 8,504. Intrauterine infection was diagnosed and treated more often in the second period (7.1% vs. 2.6%). The incidence of early-onset group B streptococcus sepsis was significantly lower in the second period than in the first period [0.2% vs. 0.4%; OR 0.5 (0.3-0.9)] and survival without disability higher [80% vs. 52%; OR 4.5 (1.4-16.5)]. However, in both periods the overall incidence of neonatal sepsis (3.6% vs. 3.5%) and overall mortality because of sepsis (14.3% vs.13.1%) were similar. CONCLUSIONS Although the early detection of clinical signs of intrauterine infection might have been effective for the prevention of serious sequelae of early-onset group B streptococcus sepsis the overall incidence and mortality from neonatal sepsis remained unchanged. Evaluation of preventive measures for early-onset group B streptococcus sepsis should always take the incidence of neonatal sepsis caused by other pathogens into account.

Abstract
Risk indicators play an important role in the active prevention of neonatal Early-Onset GBS-related Disease (EOD). We studied the associations between potential risk indicators and the occurrence of EOD by means of a case-control study. All cases of EOD delivered in the Academic Medical Centre in Amsterdam between January 1988 and December 1995 were included. For each case we selected 3 controls, matched for date and time of birth. The association between continuous risk indicators and the occurrence of EOD was assessed using spline functions. Multivariable logistic regression analysis was performed to determine which risk indicators contributed independently. Forty-one cases were compared with 123 controls. In the multivariable analysis, gestational age < 37 weeks and intrapartum temperature > or = 37.4 degrees C showed to be statistically significant risk indicators for EOD, with odds ratios of 2.5 per week gestation and 1.6 per 0.1 degree C, respectively. After cesarean section the risk of EOD was significantly decreased (OR 0.13). Of the other potential risk indicators only prelabor rupture of membranes showed an increased risk, although the association was not statistically significant. Prolonged duration of ruptured membranes had no additional merit. Risk indicators that should be taken into account in strategies to prevent EOD are increased maternal temperature and decreased gestational age.

Abstract
Retrospectively, morbidity and mortality of neonatal early onset group B streptococcal (GBS) infection were established. Risk factors and prognostic factors were determined. Between 1985 and 1993, 78 patients with early onset GBS disease were identified. The overall mortality rate was 23%. In 60 of 73 cases (82%) at least one of the investigated risk factors was present. Low birth weight was not an independent risk factor. Outcome of 44 of 60 survivors (73%) at the age of at least one year was obtained. Almost 30% of them had sequelae. The most important were spastic disorders and delayed psychomotor development. In 42% of patients with symptoms of GBS-infection within six hours after birth sequelae occurred. There were no sequelae among patients with symptoms after 6 hours. All 9 severely brain damaged infants showed symptoms shortly after birth. Mortality and adverse outcome rate were higher in infants with low gestational age or low 5 minute Apgar scores. Early treatment resulted in less mortality, but not in less sequelae. GBS-sepsis still causes significant mortality and leaves a substantial number of survivors damaged. Alertness to GBS-infection, even in the absence of risk factors, remains crucial for early treatment and good outcome.

Abstract
Group B streptococcus is the leading cause of neonatal septicaemia. Major risk factors for early-onset disease are heavy maternal GBS colonization preterm delivery (and related low birthweight), preterm rupture of membranes, prelabour rupture of membranes, intrapartum fever, GBS urinary infection and low levels of maternal serum anti-GBS antibodies. Screening for maternal GBS colonization, a part of most current preventive strategies, can be targeted on all pregnant women or only on those with recognizable risk factors, and can be implemented antepartum or intrapartum. A culture in a selective broth is the 'gold standard' for detection of GBS colonization. The lower vagina (introitus) is the most suitable site for culturing, with the optional addition of an anorectal sample. The sensitivity of the available rapid GBS antigen tests for vagina samples seems too low to advocate their general use. Intrapartum prophylaxis with ampicillin, preferably targeted on GBS-colonized parturients with risk factors is, at present, the only strategy with established efficacy and safety to prevent early-onset infection. Vaginal chlorhexidine disinfection during labour in all women may, in addition offer a minor contribution to prevention. Late-onset GBS disease is unlikely to be reduced by these strategies. In the future, immunoprophylaxis may well prove to be the most safe and efficacious alternative to prevent GBS septicaemia, irrespective of age of onset, although protection of (very) preterm infants is unlikely.

Abstract
OBJECTIVE To evaluate the effect of vaginal disinfection with chlorhexidine gel during labor on vertical transmission of group B streptococcus, as a method to prevent vertical transmission and subsequent neonatal early onset group B streptococcal disease. STUDY DESIGN A prospective study with randomization of 1020 parturients to one of three groups as soon as labor started. In all parturients, anus, introitus and cervix were cultured semiquantitatively. Two groups were treated double-blindly with 10 ml of either a 0.3% chlorhexidine gel or a placebo gel, applicated around the portio and into the fornices. If labor still continued, a second application was given after 10 h. The third group received no treatment. Ear, pharynx and umbilicus of all newborns were also cultured semiquantitatively. RESULTS Nine hundred and eighty one women were evaluated. The overall incidence of group B streptococcal carriership was 19.4%. Vertical transmission was 52.4% in the chlorhexidine group, 71.4% in the placebo group and 66.7% in the control group (P = 0.069). When testing the transmission rates for the chlorhexidine versus the combined placebo plus control group (69.3%), the difference was 16.9% (P = 0.026). CONCLUSION Vaginal disinfection with a chlorhexidine gel during labor modestly reduces group B streptococcal vertical transmission. Because the method is cheap, simple and safe, it should be considered for routine use. Our results indicate that it may reduce the incidence of early onset group B streptococcal sepsis by 2-32%.

Abstract
OBJECTIVES To evaluate the sensitivity of intrapartum screening for group B streptococcal (GBS) colonization and to compare 4 rapid GBS antigen tests in vitro. DESIGN Two swabs of the lower vagina of 769 parturients were taken; one swab was cultured, the other was frozen at -70 degrees C until antigen testing with the Group B Strep Test (Quidel) of the culture positive samples was performed. The Quidel test was then compared with 3 other rapid GBS antigen tests in vitro: Wellcogen Strep B (Wellcome Diagnostics), Slidex méningite Strepto B (bioMérieux) and ICON Strep B (Hybritech). The supernatant of 29 GBS cultures in Todd-Hewitt broth was tested in bacterial concentrations of 10(6), 10(7), and 10(8) Colony-forming Units (CFU)/ml, respectively. RESULTS Lower vagina GBS carrier rate was 13.4% (103/769) and heavy colonization (growth density 3 and 4 on blood agar plates) was found in 5.2% (40/769). The Group B Strep Test detected 11% (11/103) of GBS carriers, with a sensitivity for heavy colonization of 25% (10/40). In vitro none of the tests scored positively with a concentration of 10(6) CFU/ml, while with 10(7) CFU/ml the enzyme immunoassay tests (Quidel, Hybritech) were more sensitive (McNemar test, P < 0.05) than the latex agglutination tests (Wellcome Diagnostics, bioMérieux). CONCLUSIONS Although in vitro the enzyme immunoassay tests are more sensitive than the latex agglutination tests, sensitivity in vivo is too low to recommend the use of rapid antigen tests for general screening.
