RESUMO
Making a distinction between facial palsy due to Lyme neuroborreliosis (LNB) and idiopathic facial palsy (IFP) is of importance to ensure timely and adequate treatment. The study objective was to assess incidence and patient characteristics of facial palsy due to LNB. Hospital records were reviewed of adult patients with facial palsy visiting the departments of neurology and/or otorhinolaryngology of Gelre hospitals between June 2007 and December 2017. Gelre hospitals are located in an area endemic for Lyme borreliosis. Patients with LNB had pleocytosis and intrathecal antibody production or pleocytosis with positive IgG serology. Patients with IFP had negative serology. Clinical characteristics were compared between patients with LNB and patients with IFP. Five hundred and fifty-nine patients presented with facial palsy, 4.7% (26) had LNB and 39.4% (220) IFP. The incidence of facial palsy due to LNB was 0.9/100 000 inhabitants/year. Over 70% of patients with facial palsy due to LNB did not report a recent tick bite and/or erythema migrans (EM). Patients with facial palsy due to LNB presented more often in July to September (69.2% vs. 21.9%, P < 0.001), and had more often headache (42.3% vs. 15.5%, P < 0.01). To reduce the risk of underdiagnosing LNB in an endemic area, we recommend testing for LNB in patients with facial palsy in summer months especially when presenting with headache, irrespective of a recent tick bite and/or EM.

OBJECTIVES: There is controversy whether non-specific symptoms can be related to previous Lyme borreliosis (LB). Positive serology can be considered a proxy for previous or persistent LB. We assessed non-specific symptoms and serology in patients suspected of LB referred to a Lyme centre. METHODS: Included were adult patients who visited a Lyme centre between 2008 and 2014. Before medical consultation, serum samples were taken and questionnaires on non-specific symptoms completed. The prevalence of non-specific symptoms was calculated for patients with positive and negative IgG serology. Logistic regression was used to obtain odds ratios (ORs) with 95% confidence interval (CI) for an association between positive serology and non-specific symptoms. RESULTS: Of 1439 included patients, 31.6% (455/1439) had positive serology. The most common non-specific symptoms were severe fatigue (61.4%, 883/1439), sleep disturbances (54.8%, 789/1439) and stiffness of neck/back (52.6%, 757/1439). The prevalence of severe fatigue was 53.0% (241/455) in patients with positive serology vs. 65.2% (642/984) in patients with negative serology (OR = 0.74; 95% CI, 0.58-0.94). The prevalence of sleep disturbances was respectively 46.2% (210/455) vs. 58.8% (579/984) (OR = 0.73; 95% CI, 0.58-0.93). The prevalence of stiffness of neck/back was respectively 47.7% (217/455) vs. 54.9% (540/984) (OR = 0.85; 95% CI, 0.67-1.06). CONCLUSIONS: In patients referred to a Lyme centre, non-specific symptoms did not occur more frequently in patients with positive serology compared to patients with negative serology. Hence, a questionnaire on non-specific symptoms cannot be used for identifying patients with possible post-LB symptoms in clinical practice.

OBJECTIVES: Current guidelines for the empirical antibiotic treatment predict the presence of third-generation cephalosporin-resistant enterobacterial bacteraemia (3GCR-E-Bac) in case of infection only poorly, thereby increasing unnecessary carbapenem use. We aimed to develop diagnostic scoring systems which can better predict the presence of 3GCR-E-Bac. METHODS: A retrospective nested case-control study was performed that included patients ≥18 years of age from eight Dutch hospitals in whom blood cultures were obtained and intravenous antibiotics were initiated. Each patient with 3GCR-E-Bac was matched to four control infection episodes within the same hospital, based on blood-culture date and onset location (community or hospital). Starting from 32 commonly described clinical risk factors at infection onset, selection strategies were used to derive scoring systems for the probability of community- and hospital-onset 3GCR-E-Bac. RESULTS: 3GCR-E-Bac occurred in 90 of 22 506 (0.4%) community-onset infections and in 82 of 8110 (1.0%) hospital-onset infections, and these cases were matched to 360 community-onset and 328 hospital-onset control episodes. The derived community-onset and hospital-onset scoring systems consisted of six and nine predictors, respectively. With selected score cut-offs, the models identified 3GCR-E-Bac with sensitivity equal to existing guidelines (community-onset: 54.3%; hospital-onset: 81.5%). However, they reduced the proportion of patients classified as at risk for 3GCR-E-Bac (i.e. eligible for empirical carbapenem therapy) with 40% (95%CI 21-56%) and 49% (95%CI 39-58%) in, respectively, community-onset and hospital-onset infections. CONCLUSIONS: These prediction scores for 3GCR-E-Bac, specifically geared towards the initiation of empirical antibiotic treatment, may improve the balance between inappropriate antibiotics and carbapenem overuse.

A two-step testing strategy is recommended in serological testing for Lyme borreliosis; positive and indeterminate enzyme-linked immunosorbent assay (ELISA) results are confirmed with immunoblots. Several ELISAs quantify the concentration of antibodies tested, however, no recommendation exists for an upper cut-off value at which an IgG ELISA is sufficient and the immunoblot can be omitted. The study objective was to determine at which IgG antibody level an immunoblot does not have any additional predictive value compared to ELISA results. Data of adult patients who visited a tertiary Lyme centre between 2008 and 2014 were analysed. Both an ELISA (Enzygnost Lyme link VlsE IgG) and immunoblot (recomLine blot Borrelia) were performed. Clinical data were extracted from the patient's digital medical record. Positive predictive values (PPVs) for either previous or active infection with Borrelia burgdorferi s.l. were calculated for different cut-off ELISA IgG antibody levels where the immunoblot was regarded as reference test. In total, 1454 patients were included. According to the two-step test strategy, 486 (33%), 69 (5%) and 899 (62%) patients had positive, indeterminate and negative Borrelia IgG serology, respectively. At IgG levels of 500â¯IU/ml and higher, all immunoblots were positive, resulting in a 100% PPV (95% CI: 97.0-100). At IgG levels of 200â¯IU/ml and higher, the PPV was 99.3% (95% CI: 97.4-99.8). In conclusion, at IgG levels of 200â¯IU/ml and higher, an ELISA was sufficient to detect antibodies to Borrelia burgdorferi s.l. At those IgG levels, a confirmatory immunoblot may be omitted in patients referred to a tertiary Lyme centre. Before these results can be implemented in routine diagnosis of Lyme borreliosis, confirmation of the results is necessary in other patient populations and using other quantitative ELISAs and immunoblots.

The prevalence of patients colonized with extended-spectrum beta-lactamase (ESBL)-producing bacteria increases, especially in long-term-care facilities (LTCFs). Identification of ESBL carriers at hospital admission is relevant for infection control measures and antibiotic therapy for nosocomial infections. We aimed to develop a prediction rule for ESBL carriage at hospital admission for patients admitted from home and LTCFs, and to quantify incidences of nosocomial infections caused by ESBL-producing bacteria. The ESBL-carrier status was determined of patients admitted from LTCFs and from home settings in four hospitals in the Netherlands using perianal swabs obtained within 48 hours of admission. Risk factors for ESBL carriage were assessed. Infections caused by ESBL-producing bacteria were identified retrospectively. Among 1351 patients, 111 (8.2%) were ESBL carriers at admission: 50/579 (8.6%) admitted from LTCFs and 61/772 (7.9%) from home settings (p 0.63). Previous ESBL carriage and previous hospital admission were risk factors for ESBL carriage in multivariable analysis. The area under the curve of the receiver operating characteristic curve of the model was 0.64 (95% CI 0.58-0.71). Presence of ≥1 risk factor (n = 803; 59%) had sensitivity of 72%. Incidences of nosocomial infections caused by ESBL-producing bacteria were 45.5/10,000 and 2.1/10,000 admission days for ESBL carriers and non-carriers, respectively (p <0.05). In conclusion, prevalence of ESBL carriage at hospital admission was 8.2%, and was comparable among patients admitted from LTCF and home. A clinically useful prediction rule for ESBL carriage at admission could not be developed. The absolute incidence of nosocomial infections by ESBL-producing bacteria was low, but higher among patients carrying ESBL-producing bacteria at the time of hospital admission.

We conducted a double-blind, placebo-controlled randomized trial to assess the effect of single-dose prophylaxis using co-trimoxazole (960 mg) (n = 46) or ciprofloxacin (500 mg) (n = 43) vs. placebo (n = 51) before urinary catheter removal on significant bacteriuria (SBU) (primary outcome) and urinary tract infection (UTI) in surgical patients with scheduled bladder drainage for 3-14 days. SBU was determined directly after catheter removal, and UTI 12-14 days after catheter removal. After 12-14 days, incidences of SBU were 19%, 19% and 33% for patients receiving ciprofloxacin, co-trimoxazole and placebo, respectively (p ns), and incidences of UTI were 3%, 0% and 3% for patients receiving ciprofloxacin, co-trimoxazole and placebo, respectively (p ns).

Campylobacter is the most common cause of bacterial gastroenteritis worldwide. This study describes regional and seasonal differences among culture-proven Campylobacter infections in The Netherlands in 2000-2004. Data were used from two ongoing projects in The Netherlands, covering 3 million and 8 million inhabitants, respectively, for surveillance of infectious diseases. The incidence of Campylobacter infection was highest in the south of The Netherlands (55.7/100,000 vs. an average of 39.1/100,000 in other regions). The incidence in urbanised areas was 41.9/100,000 vs. 32.4/100,000 in rural areas. High stable rates of resistance to fluoroquinolones (35%) were observed. Resistance to erythromycin increased from 1.9% (in 2001) to 2.7% (in 2004). The highest rates of resistance to erythromycin were found in the south. Resistance rates increased with increasing urbanisation, most obviously for fluoroquinolones (35.9% urban vs. 27.10% rural). An inverse relationship was observed between the incidence of infection (high in summer, low in winter) and resistance to both fluoroquinolones and macrolides. Resistance to fluoroquinolones was higher in travel-related infections (54%) than in endemic infections (33%). Differences in regional incidence and resistance rates of Campylobacter infections were found. Foreign travel appeared to be associated with higher resistance rates. Given the high fluoroquinolone resistance rate, empirical treatment of severe, microbiologically confirmed, Campylobacter infection with a fluoroquinolone should be discouraged, pending susceptibility testing.
