Validity of a smartwatch for detecting atrial fibrillation in patients after heart valve surgery: a prospective observational study.

OBJECTIVES: Atrial fibrillation (AF) is a common early arrhythmia after heart valve surgery that limits physical activity. We aimed to evaluate the criterion validity of the Apple Watch Series 5 single-lead electrocardiogram (ECG) for detecting AF in patients after heart valve surgery. DESIGN: We enrolled 105 patients from the University Hospital of North Norway, of whom 93 completed the study. All patients underwent single-lead ECG using the smartwatch three times or more daily on the second to third or third to fourth postoperative day. These results were compared with continuous 2-4 days ECG telemetry monitoring and a 12-lead ECG on the third postoperative day. RESULTS: On comparing the Apple Watch ECGs with the ECG monitoring, the sensitivity and specificity to detect AF were 91% (75, 100) and 96% (91, 99), respectively. The accuracy was 95% (91, 99). On comparing Apple Watch ECG with a 12-lead ECG, the sensitivity was 71% (62, 100) and the specificity was 92% (92, 100). CONCLUSION: The Apple smartwatch single-lead ECG has high sensitivity and specificity, and might be a useful tool for detecting AF in patients after heart valve surgery.

Chemsex Among Men Who Have Sex With Men: A Systematic Scoping Review of Research Methods.

Chemsex refers to the use of psychoactive substances with sex. We carried out a systematic scoping review of methodological characteristics of chemsex research among men who have sex with men (MSM), published between 2010 and 2020. For inclusion, chemsex had to be the main focus, and studies had to specify GHB/GBL, stimulant (amphetamine, crystal meth, ecstasy/MDMA, cathinones, cocaine) and/or ketamine use with sex as a variable. From 7055 titles/abstracts, 108 studies were included, mostly cross-sectional, and from Western countries. About one-third of studies recruited exclusively from clinical settings. A majority of these recruited from sexually transmitted infection (STI) clinics. The included quantitative studies analyzed possible associations between chemsex and STI health (40%), mental health (15%), drug health (12%), sexological health (10%), and post-diagnostic HIV health (7%). Most studies included GHB/GBL and crystal meth in their operationalization of chemsex. Definitions and operationalizations of chemsex vary greatly in the literature, and researchers of chemsex among MSM should consider ways in which this variation impacts the validity of their results. More studies are needed among MSM in non-high income and non-Western countries, and examination of possible links between chemsex and post-diagnostic HIV health, sexological health, and mental health.

Prevalence of mental distress and factors associated with symptoms of major depression among people living with HIV in Norway.

For people living with HIV (PLHIV) who can access lifesaving treatment, HIV has become a chronic lifelong condition; however, PLHIV have more mental and somatic comorbidities than their HIV-negative peers. In this cross-sectional study, we assessed the prevalence of mental distress and identified factors associated with major depression among 244 well-treated PLHIV residing in Norway. Participants completed validated questionnaires covering mental and somatic health. The prevalence of mental distress, defined as a score on the Hopkins Symptom Check List-25 >1.75, was 32%, and that of symptoms of major depression, defined as a score on the Beck Depression Inventory-II ≥20, was 15%. The factors associated with major depressive symptoms identified using logistic regression were risk of drug abuse (adjusted odds ratio (AOR) 15.1, 95% confidence interval (CI) 3.28, 69.3), fatigue (AOR 12.5, 95% CI 3.90, 40.0), trouble sleeping (AOR 7.90, 95% CI 2.85, 21.9), African origin (AOR 3.90, 95% CI 1.28, 11.9), low education (AOR 3.31, 95% CI 1.18, 9.30), and non-disclosure (AOR 3.22, 95% CI 1.04, 10.0). Our findings indicate that the prevalence rates of mental distress and major depressive symptoms are higher among well-treated PLHIV residing in Norway than in the general population. These conditions are under-diagnosed and under-treated, and increased awareness is needed.

Factors associated with health-related quality of life in people living with HIV in Norway.

BACKGROUND: Despite the advances in the treatment of HIV, people living with HIV (PLHIV) still experience impairment of health-related quality of life (HRQOL). The aim of the study was to explore factors associated with HRQOL in a well-treated Norwegian HIV population. METHODS: Two hundred and forty-five patients were recruited from two outpatient clinics to participate in this cross-sectional study of addiction, mental distress, post-traumatic stress disorder, fatigue, somatic health, and HRQOL. The latter was measured using the 36-Item Short Form Health Survey (SF-36). Stepwise multiple linear regression analysis was used to examine the adjusted associations between demographic and disease-related variables and HRQOL. RESULTS: The study population was virologically and immunologically stable. Their mean age was 43.8 (SD = 11.7) years, 131 (54%) were men, and 33% were native Norwegians. Compared with the general population (published in previous studies), patients reported worse SF-36 scores for five of eight domains: mental health, general health, social function, physical role limitation, and emotional role limitation (all p < 0.001). Compared with men, women reported better SF-36 scores within the domains vitality (63.1 (23.6) vs. 55.9 (26.7), p = 0.026) and general health (73.4 (23.2) vs. 64.4 (30.1), p = 0.009). In the multivariate analyses, higher SF-36- physical component score values were independently associated with young age (p = 0.020), being employed, student, or pensioner (p = 0.009), low comorbidity score (p = 0.015), low anxiety and depression score (p = 0.015), being at risk of drug abuse (p = 0.037), and not being fatigued (p < 0.001). Higher SF-36-mental component score values were independently associated with older age (p = 0.018), being from a country outside Europe or from Norway (p = 0.029), shorter time since diagnosis, low anxiety and depression score (p < 0.001), answering 'no' regarding alcohol abuse (p = 0.013), and not being fatigued (p < 0.001). CONCLUSIONS: HRQOL was poorer in PLHIV than in the general population in Norway. It is important to focus on somatic and mental comorbidities when delivering health-care services in the ageing population of PLHIV to improve HRQOL even among a well-treated group of PLHIV as found in Norway.

"They make a difference": a qualitative study of providers' experiences of peer support in outpatient clinics for people living with HIV.

BACKGROUND: Although the life expectancy of people living with HIV has increased, they are still often disconnected from society through stigma and discrimination. Peer support has been found to increase social support. Given the limited research on peer support from the providers' perspective, this study explored how peer supporters experience their roles and contributions in outpatient clinics (OPCs). Additionally, healthcare professionals' perceptions of working with peer supporters in OPCs were examined.  METHODS: This qualitative study included purposively selected peer supporters (n = 10) and healthcare professionals (n = 5) from five OPCs in Norway in 2020. In-depth interviews and focus group discussions were conducted in Norwegian or English, using interview guides. Interview transcripts were analysed in NVivo 12 using reflexive and collaborative thematic analysis. RESULTS: The results show that peer supporters experience mutual support through emotional and honest interactions. Further, the peer supporters found it essential to negotiate with the service users about their preconception of HIV, confront their views through dialogue, and replicate positive experiences by being credible role models. The participants expressed that integrating peer support in the OPCs' usual care processes increased the prospect of equitable services. Quality of peer support and role clarity were identified as critical components. The results demonstrate that emotional and honest conversations promote support between peers and that peer supporters identify a need for a reframed understanding of HIV by modelling plausible alternative interpretations and coping experiences. CONCLUSIONS: This study contributes to knowledge on how peer support can meet the needs of people living with HIV. Incorporating people living with HIV in the co-production and distribution of healthcare services may improve the knowledge and perspectives in healthcare services. However, the skill standards of peer supporters should be addressed when implementing peer support in usual care.

Health characteristics associated with chemsex among men who have sex with men: Results from a cross-sectional clinic survey in Norway.

BACKGROUND: Chemsex typically involves drugs such as GHB/GBL, crystal meth and mephedrone, and is increasingly common among MSM. The behaviour has been found to be associated with sexually transmitted infections (STIs) and mental health problems. We aimed to assess the extent of chemsex engagement and associations with different aspects of health, among MSM attending a free specialist walk-in clinic for STIs in Oslo, Norway. METHODS: Anonymous cross-sectional survey data was collected from June to October 2016. Differences in STI health (chlamydia, gonorrhoea, syphilis, HIV diagnoses), mental health (depression/anxiety) and internalised homonegativity between MSM using and not using GHB/GBL, crystal meth, mephedrone, cocaine or ketamine with sex in the last year were assessed descriptively and in a multivariate logistic regression model. The predictors were number of self-reported chlamydia, gonorrhoea or syphilis diagnoses, HIV diagnosis, depression/anxiety, and degree of internalised homonegativity. We adjusted for age, education level and having lived abroad. RESULTS: Of the 518 MSM respondents, 17% reported sexualised use of either GHB/GBL, crystal meth, mephedrone, cocaine or ketamine in the last year (chemsex). We found significant positive associations between chemsex and self-reported HIV diagnoses (adjusted odds ratio [aOR] = 3.26, 95%CI = 1.37-7.76), number of reported chlamydia, gonorrhoea or syphilis diagnoses in the last year (aOR = 1.63, 95%CI = 1.18-2.12), having lived more than one year abroad (aOR = 2.10, 95%CI = 1.20-3.65), but no significant association with depression/anxiety (aOR = 1.02, 95%CI = 0.53-1.93), nor internalised homonegativity (aOR = 0.62, 95%CI = 0.33-1.19). CONCLUSION: Chemsex engagement in Norway is relatively low compared to findings from STI clinics in other European countries, and GHB/GBL and cocaine the two most commonly used drugs with sex. Chemsex was more common among MSM having lived more than one year abroad, reporting HIV diagnoses and a higher number of either chlamydia, gonorrhoea or syphilis diagnoses in the last year. Health care providers need to be made aware of chemsex as a behavioural phenomenon among MSM, and special care should be afforded to MSM living with HIV and being diagnosed with STIs.

A national intercalated medical student research program - student perceptions, satisfaction, and factors associated with pursuing a PhD.

BACKGROUND: To counteract a decreasing number of physician-scientists, a national intercalated Medical Student Research Programme (MSRP) was launched in Norway in 2002. We aimed to assess whether the students' favourable perceptions and satisfaction with the program had prevailed since the inception in 2002 and until 2015, and to identify factors associated with pursuing a PhD. METHODS: The study was an incorporation of data from two previous national evaluations of the MSRP performed in 2007 and 2015. We used electronic questionnaires to explore demographic characteristics, area and type of research, student satisfaction, and future scientific goals. In 2007, questionnaires were sent to all 208 students, and 183 (88%) replied. In 2015, the corresponding numbers were 279, and 240 (86%). Categorical data were analysed using either Kruskal-Wallis or Pearson's chi square test. Differences between sample means were assessed with Student`s t-test while logistic regression was used to test associations between selected covariates and the students' ambitions to pursue a PhD degree. RESULTS: Overall, the student satisfaction was 79%. However, more students in 2015 received less regular and less supervision time and expressed a need for more of it. Seventy-seven per cent expressed an ambition to pursue a PhD. Students were more likely to have a PhD ambition if they were satisfied with the program, had a supervisor with high expectations for them, or had already published some of their results. At both time points, students (86% vs. 89%) responded that the MSRP had a positive impact on their regular curriculum achievements. CONCLUSIONS: The high degree of satisfaction with the national MSRP among undergraduate students has prevailed since the inception in 2002. By far, the program has also met its goal to increase the number of aspiring physician-scientists. However, to maintain that goal over time, adequate and personal supervision is a prerequisite.

Peer support in an outpatient clinic for people living with human immunodeficiency virus: a qualitative study of service users' experiences.

BACKGROUND: Although human immunodeficiency virus (HIV) has become a manageable condition with increasing life expectancy, people living with HIV (PLHIV) are still often isolated from society due to stigma and discrimination. Peer support provides one avenue for increased social support. Given the limited research on peer support from the perspective of PLHIV, this study explored their experiences of peer support organised by healthcare professionals in an outpatient clinical setting. METHODS: The study used a qualitative, descriptive research design for an in-depth understanding of peer support provided to PLHIV in the context of outpatient clinics. Healthcare professionals contributed to the recruitment of 16 participants. We conducted in-depth interviews about participants' experiences of peer support, and performed a directed content analysis of the data. Further, we sorted the data into pre-determined categories. RESULTS: The pre-determined categories constituted attachment, social integration, an opportunity for nurturance, reassurance of worth, reliable alliance, and guidance. The identified themes were: gained emotional support, disclosure behaviour allowed garnering of emotional support, non-disclosure promoted the need to meet a peer, experienced a sense of belonging, activated an opportunity for mutual support, means to re-establish belief in one's own worth, perceived a positive affirmation of disease management, facilitated dialogue about disease management, the outpatient clinic as a safe place, and a setting for flexible, individualised support. CONCLUSIONS: This study highlights the peer support experiences of PLHIV in the context of outpatient clinics. The participants' experiences align with previous findings, showing that peer support contributes to mutual emotional support between peers. This is particularly important in cultures of non-disclosure where PLHIV experience intersectional stigma. Additionally, our results show outpatient clinics to be supportive surroundings for facilitating peer support, ensuring confidentiality in peer support outreach. Therefore, peer support contributes positively to individualising outpatient clinic services to meet the changing needs of PLHIV.

Prevalence and predictors of fatigue among people living with HIV in Norway.

Fatigue is the most commonly noted symptom among people living with human immunodeficiency virus (PLHIV). The aim of this study was to investigate the prevalence and predictors of fatigue among PLHIV in Norway. Two hundred and forty-four people were recruited from two hospitals to participate in a survey, which contained seven instruments used to investigate mental health, addiction, quality of life, and fatigue. More than a third of the participants (38.5%) suffered from fatigue. Predictors of fatigue were the presence of mental distress (adjusted odds ratio [AOR] 8.98, 95%CI 3.81, 21.15), multimorbidity (AOR 5.13, 95%CI 1.40, 18.73), living alone (AOR 2.99, 95%CI 1.36, 6.56), trouble sleeping (AOR 2.67, 95%CI 1.06, 6.71), and increased body pain (AOR 1.44, 95%CI 1.25, 1.67). To improve the quality of life for many PLHIV, the continuum of HIV care must address fatigue and its predictors.

Tenofovir as a treatment option for multiple sclerosis.

Some antiretroviral medications are also inhibitors of EBV. We describe a patient with highly active MS who was infected with HIV and started HIV-treatment containing tenofovir alafenamide (TAF), a potent inhibitor of EBV lytic reactivation. Her MS was in complete remission during this treatment, and she had new radiological disease activity again after switching to tenofovir disoproxil fumarate, a HIV drug with less potent activity against EBV replication. Based on the recently detected mechanism of TDF and TAF, we suggest that further studies on these drugs in MS are warranted.

Empirical prescribing of penicillin G/V reduces risk of readmission of hospitalized patients with community-acquired pneumonia in Norway: a retrospective observational study.

BACKGROUND: Norwegian guideline recommendations on first-line empirical antibiotic prescribing in hospitalised patients with community-acquired pneumonia (CAP) are penicillin G/V in monotherapy, or penicillin G in combination with gentamicin (or cefotaxime) in severely ill patients. The aim of this study was to explore how different empirical antibiotic treatments impact on length of hospital stay (LOS) and 30-day hospital readmission. A secondary aim was to describe median intravenous- and total treatment duration. METHODS: We included CAP patients (≥18 years age) hospitalised in North Norway during 2010 and 2012 in a retrospective study. Patients with negative chest x-ray, malignancies or immunosuppression or frequent readmissions were excluded. We collected data on patient characteristics, empirical antibiotic prescribing, treatment duration and clinical outcomes from electronic patient records and the hospital administrative system. We used directed acyclic graphs for statistical model selection, and analysed data with mulitvariable logistic and linear regression. RESULTS: We included 651 patients. Median age was 77 years [IQR; 64-84] and 46.5% were female. Median LOS was 4 days [IQR; 3-6], 30-day readmission rate was 14.4% and 30-day mortality rate was 6.9%. Penicillin G/V were empirically prescribed in monotherapy in 51.5% of patients, penicillin G and gentamicin in combination in 22.9% and other antibiotics in 25.6% of patients. Prescribing other antibiotics than penicillin G/V monotherapy was associated with increased risk of readmission [OR 1.9, 95% CI; 1.08-3.42]. Empirical antibiotic prescribing was not associated with LOS. Median intravenous- and total treatment duration was 3.0 [IQR; 2-5] and 11.0 [IQR; 9.8-13] days. CONCLUSIONS: Our findings show that empirical prescribing with penicillin G/V in monotherapy in hospitalised non-severe CAP-patients, without complicating factors such as malignancy, immunosuppression and frequent readmission, is associated with lower risk of 30-day readmission compared to other antibiotic treatments. Median total treatment duration exceeds treatment recommendations.

The impact of age on risk assessment, therapeutic practice and outcome in candidemia.

BACKGROUND: In Norway, the epidemiological situation of candidemia is followed closely. We have previously demonstrated the highest incidence of candidemia in elderly >65 years of age. However, knowledge of other aspects of this infection is lacking. OBJECTIVE: The aim of this nationwide, retrospective study was to examine risk factors, therapeutic practice and outcome in adult candidemia patients according to age. METHODS: We retrieved data from medical records from patients who developed candidemia in Norway between 1 January 2008 and 31 December 2012. Data were analyzed according to age, younger patients being between 18 and 65 years, elderly being ≥65 years of age. RESULTS: From 771 eligible patients, 738 patients (95.7%) were included (58% men, mean age 65.2 years, 58.1% being ≥65 years). Exposure to health-care related risk factors for candidemia were significantly more common in the younger patients (neutropenia, central venous catheter, mechanical ventilation and chemotherapy) who received empirical treatment more often than the elderly (29.8% vs. 21.7%, p = .01). More elderly did not received any antifungal therapy (27.3% vs 16.8%, p < 0001) and had higher mortality compared to younger patients (45.5% vs 23.9%, p < .0001). In the study population, mortality was higher with age (per 10-years increase, OR 1.43;1.28-1.59, p < 0.0001), in patients not receiving targeted therapy (OR 2.5; CI 1.82-3.36, p < .0001) or any therapy at all (OR 4.64; 3.23-6.68, p < .0001). CONCLUSIONS: Risk factors for candidemia, treatment and outcome differed significantly according to age. Given the increasing numbers of elderly, scrutiny on our clinical practice is warranted.

Springboard to an academic career-A national medical student research program.

Over the last decades there has been a decline in the recruitment of medical students into academia in all medical fields. Concurrently, medical research has increasingly included other disciplines in multidisciplinary convergence, introducing an unmet recruitment gap and requirement for medical researchers. To counteract the trend and recruit students to academic medicine, a national intercalated Medical Student Research Program (MSRP) was established in Norway in 2002. A preliminary evaluation in 2009 suggested that the MSRP had resulted in recruitment, but could not conclude on a lasting effect beyond graduation in a study that did not include any controls. These results led us to hypothesize that the MSRP could increase the number of PhD degrees and attract medical students towards academic medicine. Adopting a case cohort design, we here report that the intercalated MSRP had a significant impact of the throughput of physician-scientists to PhD, by increasing the rate of PhD completion 10-fold (p<0.001). Moreover, almost twice as many MSRP physicians reported an academic aspiration (49% vs 22%, p<0.001). Results suggested that an MSRP-like approach could efficiently address the unmet recruitment gap and strengthen the medical disciplines in medical research.

Predictors of HIV Risk Behaviors Among a National Sample of Russian Men Who Have Sex with Men.

Russia has one of the fastest growing HIV epidemics in the world and is at the point of transitioning from injection drug use to sexual transmissions. We sought to identify factors associated with unprotected sex among men who have sex with men (MSM) in Russia, separately for Moscow, St. Petersburg and the rest of the country. Multivariable data from a national cross-sectional study (n = 5035) demonstrate that significant correlates of unprotected anal intercourse (UAI) with a non-steady partner across all areas were visiting sex-related venues (AOR range 1.35-1.96) and access to condoms (AOR range 0.37-0.52). In Moscow and St. Petersburg, being HIV-positive was correlated with UAI (AOR 2.13 and 2.69). The dynamics of the HIV epidemic among MSM in Russia appear to be both similar, and different, across various areas and factors associated with unprotected sex should be seen as part of an environment of exogenous factors impacting MSM's sexual behaviors.

Primary immunodeficiency diseases: Genomic approaches delineate heterogeneous Mendelian disorders.

BACKGROUND: Primary immunodeficiency diseases (PIDDs) are clinically and genetically heterogeneous disorders thus far associated with mutations in more than 300 genes. The clinical phenotypes derived from distinct genotypes can overlap. Genetic etiology can be a prognostic indicator of disease severity and can influence treatment decisions. OBJECTIVE: We sought to investigate the ability of whole-exome screening methods to detect disease-causing variants in patients with PIDDs. METHODS: Patients with PIDDs from 278 families from 22 countries were investigated by using whole-exome sequencing. Computational copy number variant (CNV) prediction pipelines and an exome-tiling chromosomal microarray were also applied to identify intragenic CNVs. Analytic approaches initially focused on 475 known or candidate PIDD genes but were nonexclusive and further tailored based on clinical data, family history, and immunophenotyping. RESULTS: A likely molecular diagnosis was achieved in 110 (40%) unrelated probands. Clinical diagnosis was revised in about half (60/110) and management was directly altered in nearly a quarter (26/110) of families based on molecular findings. Twelve PIDD-causing CNVs were detected, including 7 smaller than 30 Kb that would not have been detected with conventional diagnostic CNV arrays. CONCLUSION: This high-throughput genomic approach enabled detection of disease-related variants in unexpected genes; permitted detection of low-grade constitutional, somatic, and revertant mosaicism; and provided evidence of a mutational burden in mixed PIDD immunophenotypes.

An audit and feedback intervention study increased adherence to antibiotic prescribing guidelines at a Norwegian hospital.

BACKGROUND: Appropriate antibiotic prescribing is associated with favourable levels of antimicrobial resistance (AMR) and clinical outcomes. Most intervention studies on antibiotic prescribing originate from settings with high level of AMR. In a Norwegian hospital setting with low level of AMR, the literature on interventions for promoting guideline-recommended antibiotic prescribing in hospital is scarce and requested. Preliminary studies have shown improvement potentials regarding antibiotic prescribing according to guidelines. We aimed to promote appropriate antibiotic prescribing in patients with community-acquired pneumonia (CAP) and acute exacerbations of chronic obstructive pulmonary disease (AECOPD) at a respiratory medicine department in a Norwegian University hospital. Our specific objectives were to increase prescribing of appropriate empirical antibiotics, reduce high-dose benzylpenicillin and reduce total treatment duration. METHODS: We performed an audit and feedback intervention study, combined with distribution of a recently published pocket version of the national clinical practice guideline. We included patients discharged with CAP or AECOPD and prescribed antibiotics during hospital stay, and excluded those presenting with aspiration, nosocomial infection and co-infections. The pre- and post-intervention period was 9 and 6 months, respectively. Feedback was provided orally to the department physicians at an internal-educational meeting. To explore the effect of the intervention on appropriate empirical antibiotics and mean total treatment duration we applied before-after analysis (Student's t-test) and interrupted time series (ITS). We used Pearson's χ2 to compare dose changes. RESULTS: In the pre-and post-intervention period we included 253 and 155 patients, respectively. Following the intervention, overall mean prescribing of appropriate empirical antibiotics increased from 61.7 to 83.8 % (P < 0.001), overall mean total treatment duration decreased from 11.2 to 10.4 days (P = 0.015), and prescribing of high-dose benzylpenicillin decreased from 48.8 to 38.6 % (P = 0.125). With ITS we found that six months post-intervention, the effect on appropriate empirical antibiotic prescribing had increased and sustained, while the effect on treatment duration was at pre-intervention level. CONCLUSION: The combination of audit and feedback plus distribution of a pocket version of guideline recommendations led to a substantial increase in prescribing of appropriate empirical antibiotics, which is important due to favourable effect on AMR and clinical outcomes.

Neisseria gonorrhoeae strain with high-level resistance to spectinomycin due to a novel resistance mechanism (mutated ribosomal protein S5) verified in Norway.

Gonorrhea may become untreatable, and new treatment options are essential. Verified resistance to spectinomycin is exceedingly rare. However, we describe a high-level spectinomycin-resistant (MIC, >1,024 µg/ml) Neisseria gonorrhoeae strain from Norway with a novel resistance mechanism. The resistance determinant was a deletion of codon 27 (valine) and a K28E alteration in the ribosomal protein 5S. The traditional spectinomycin resistance gene (16S rRNA) was wild type. Despite this exceedingly rare finding, spectinomycin available for treatment of ceftriaxone-resistant urogenital gonorrhea would be very valuable.

Appropriate time for test-of-cure when diagnosing gonorrhoea with a nucleic acid amplification test.

Culture is commonly regarded as the gold standard for diagnosis of Neisseria gonorrhoeae. However, nucleic acid amplification tests (NAATs) have rapidly replaced culture for diagnostics in many settings. The aim of the present study was to investigate the appropriate time for test-of-cure (TOC) when NAATs are used for diagnosis of gonorrhoea. In total, 30 patients (28 men and 2 women) provided urethral, cervical, rectal or pharyngeal specimens for TOC. All included patients, except one who did not return for second TOC before day 19, tested negative within 2 weeks after treatment with cefixime 400 mg × 1. Antimicrobial susceptibility testing showed that 68% of the culture-positive strains were resistant to ciprofloxacin. Thus, the recommended empirical treatment with ciprofloxacin in Norway should be changed immediately. TOC can be performed 2 weeks after treatment when NAATs are used for diagnosis of gonorrhoea.

Recurrent meningococcal sepsis in a presumptive immunocompetent host shown to be complement C5 deficient-a case report.

Invasive meningococcal disease is a world wide challenge. Most cases occur in immunocompetent children and young adults, but some immunodeficiencies are linked to a greater risk of invasive neisserial infections. One of these is complement component deficiencies, particularly deficiency of properdin and the terminal complement components. We describe a case of recurrent meningococcal sepsis in a young man who was later diagnosed with complete lack of complement component C5. This case report emphasizes the need of having complement deficiencies in mind when being introduced to patients with invasive Neisseria-infections.

Clinical validation of a real-time polymerase chain reaction detection of Neisseria gonorrheae porA pseudogene versus culture techniques.

BACKGROUND: Diagnosing Neisseria gonorrheae using nucleic acid amplification tests (NAATs) might increase the sensitivity, compared to cultivation. However, using NAATs has also been problematic mainly due to the close genetic relationships between different Neisseria species, resulting in false positive diagnoses. This study was conducted to clinically validate a previously published real-time polymerase chain reaction (PCR) method targeting the porA pseudogene in N. gonorrheae in comparison to culture techniques. METHODS: In total, 360 samples, urethra (n = 109), rectum (n = 84), pharynx (n = 119), and cervix (n = 48) from 185 males and 57 females, were analyzed using porA pseudogene PCR and cultivation. Sequencing of the entire porA pseudogene and the 16S rRNA gene were used to resolve discrepant results. RESULTS: Of the 360 samples, 37 were positive by both culture and PCR, however, the PCR identified 15 additional confirmed positive samples. The PCR method showed a sensitivity, specificity, positive predictive value, and negative predictive value of 100% in a preselected population. The preselected population had a true gonorrhea prevalence of 17.4%. CONCLUSIONS: The present porA pseudogene real-time PCR comprises a valuable supplement to the traditional culture techniques for diagnosis of N. gonorrheae, especially for samples from extragenital sites such as pharynx and rectum.
