RESUMEN
Infections in pregnancy are common, and although often not harmful to the woman or her unborn child, some infections may be associated with severe adverse outcomes. Pregnancy causes physiological and immunological adaptations which may make pregnant women more susceptible to infections and at increased risk of more severe illness. Infections in pregnancy represent a challenging area of concern for many specialists and general practitioners. Center for Pregnancy and Infection was developed to enhance knowledge, diagnosis, treatment, and care for pregnant women with infection in Denmark, as pointed out in this review.

Sweat chloride concentration, a diagnostic feature in cystic fibrosis (CF), reflects CF transmembrane conductance regulator (CFTR) activity. CFTR modulator therapies, especially elexacaftor/tezacaftor/ivacaftor (ETI), has improved CF outcomes. We report nationwide, real-world data on sweat chloride concentration in people with CF (pwCF) with and without modulator therapies. All Danish pwCF with a minimum of one F508del allele were included. Sweat chloride measurements were stratified by genotype and modulator treatment. Differences were assessed using mixed-effects models. We included 977 sweat chloride measurements from 430 pwCF, 71% of which were F508del homozygous. Heterozygous and homozygous ETI-treated pwCF had an estimated mean sweat chloride concentration of 43 mmol/L (95% confidence interval: 39; 48) and 43 mmol/L (39; 47), respectively-48% and 59% lower than those without treatment. High variation in concentrations remained regardless of treatment status. Despite ETI treatment, 27% heterozygous and 23% homozygous pwCF had elevated concentrations (≥60 mmol/L). These real-world data confirm a substantial decrease in sweat chloride concentration during modulator treatment, especially ETI, where mean concentrations halved. However, large variation remained, including persistently high concentrations. These findings emphasize the potential of sweat chloride concentration as a treatment response biomarker and the need to explore its heterogeneity and relationship with clinical outcomes.
RESUMEN
AIMS/HYPOTHESIS: The aim of this study was to investigate insulin secretion, insulin sensitivity, disposition index and insulin clearance by glucose tolerance status in individuals with cystic fibrosis (CF) and exocrine pancreatic insufficiency. METHODS: In a cross-sectional study, we conducted an extended (ten samples) OGTT in individuals with pancreatic-insufficient CF (PI-CF). Participants were divided into normal glucose tolerance (NGT), early glucose intolerance (EGI), impaired glucose tolerance (IGT) and CF-related diabetes (CFRD) groups. We used three different oral minimal models to assess insulin secretion, insulin sensitivity and insulin clearance during the OGTT. We evaluated insulin secretion using total secretion (Φ total), first-phase secretion (Φ dynamic) and second-phase secretion (Φ static) from the model, and we estimated the disposition index by multiplying Φ total and insulin sensitivity. RESULTS: Among 61 participants (NGT 21%, EGI 33%, IGT 16%, CFRD 30%), insulin secretion indices (Φ total, dynamic and static) were significantly lower in the CFRD group compared with the other groups. Insulin sensitivity declined with worsening in glucose tolerance (p value for trend <0.001) and the disposition index declined between NGT and EGI and between IGT and CFRD. Those with CFRD had elevated insulin clearance compared with NGT (p=0.019) and low insulin secretion (Φ total) was also associated with high insulin clearance (p<0.001). CONCLUSIONS/INTERPRETATION: In individuals with PI-CF, disposition index declined with incremental impairment in glucose tolerance due to a reduction in both insulin secretion and insulin sensitivity. Moreover in CF, reduced insulin secretion was associated with higher insulin clearance.
RESUMEN
OBJECTIVES: The HIV/AIDS epidemic has disproportionately affected men who have sex with men (MSM) since its onset. Despite important medical advancements in treatment, the enduring effects of living with HIV continue to adversely impact the health and well-being of this population. This cross-sectional nationwide study examined psychosocial and sexual health among MSM in Denmark, comparing those living with and without HIV. METHODS: Data from MSM living with HIV were collected from the SHARE study, a Danish nationwide survey that investigated psychosocial, sexual and reproductive health among people with HIV, and compared with data from MSM without HIV, retrieved from the nationally representative cohort study, Project SEXUS. Associations between HIV status and psychosocial and sexual health outcomes were examined using logistic regression models while controlling for potentially confounding variables. RESULTS: Among 369 MSM with HIV and 1002 MSM without HIV, logistic regression analyses revealed that living with HIV was significantly associated with having current symptoms of anxiety and depression and greater dissatisfaction with one's body. Additionally, MSM with HIV significantly more often than MSM without HIV reported low sexual desire, sexual inactivity, a lack of sexual needs in the last year and erectile dysfunction. Having received payment for sex was more frequently reported by MSM with HIV, as was sexualised drug use, including chemsex drugs. CONCLUSION: Compared with MSM without HIV, MSM with HIV in Denmark report a higher burden of mental health and sex life challenges.
RESUMEN
Many patients exhibit persistently reduced pulmonary diffusing capacity after coronavirus disease 2019 (COVID-19). In this study, dual test gas diffusing capacity for carbon monoxide and nitric oxide (DL,CO,NO) metrics and their relationship to disease severity and physical performance were examined in patients who previously had COVID-19. An initial cohort of 148 patients diagnosed with COVID-19 of all severities between March 2020 and March 2021 had a DL,CO,NO measurement performed using the single-breath method at 5.7 months follow-up. All patients with at least one abnormal DL,CO,NO metric (n = 87) were revaluated at 12.5 months follow-up. The DL,CO,NO was used to provide the pulmonary diffusing capacity for nitric oxide (DL,NO), the pulmonary diffusing capacity for carbon monoxide (DL,CO,5s), the alveolar-capillary membrane diffusing capacity and the pulmonary capillary blood volume. At both 5.7 and 12.5 months, physical performance was assessed using a 30 s sit-to-stand test and the 6 min walk test. Approximately 60% of patients exhibited a severity-dependent decline in at least one DL,CO,NO metric at 5.7 months follow-up. At 12.5 months, both DL,NO and DL,CO,5s had returned towards normal but still remained abnormal in two-thirds of the patients. Concurrently, improvements in physical performance were observed, but with no apparent relationship to any DL,CO,NO metric. The severity-dependent decline in DL,NO and DL,CO observed at 5.7 months after COVID-19 appears to be reduced consistently at 12.5 months follow-up in the majority of patients, despite marked improvements in physical performance.

BACKGROUND: Past and ongoing advancements in cystic fibrosis (CF) care warrant long-term analysis of the societal impact of the condition. This study aims to evaluate changes in key socioeconomic factors across three decades among people living with CF (pwCF), compared with both the general population and an early-onset chronic disease population. METHODS: This nationwide, registry-based, matched cohort study included all pwCF ≥ 18 years in Denmark in the years 1990, 2000, 2010, and 2018. Each person living with CF was matched to five individuals in the general population and five individuals living with type 1 diabetes or juvenile arthritis based on age, sex, and municipality. RESULTS: The Danish adult CF population increased nearly fourfold from 88 in 1990 to 331 in 2018, and mean age increased by ten years. The educational level of pwCF was similar to the two comparator cohorts, while pwCF were less often in employment and more often permanently outside the labor force. Personal and household income levels of the CF cohort were higher than those of the comparator cohorts. CONCLUSIONS: The disadvantage in employment for pwCF remained, but, over time, the societal profiles of the one-year CF cohorts increasingly converged with those of the comparator cohorts, indicative of improved clinical management, extended life expectancy, and the supportive role of the Danish welfare system in reducing health inequalities. Further research should be done to evaluate the effects of the newly introduced modulator therapies on employment, considering the broader societal impact and impact on quality of life.
RESUMEN
Cystic fibrosis (CF) care in Denmark has been characterized by close monitoring and pre-emptive treatment of lung disease and other CF-related complications. Continuous evaluation through data collection and commitment to clinical research has incrementally improved outcomes. This approach has been in line with best practices set forth by European Standards of Care but has also gone beyond Society standards particularly pertaining to early treatment with high-dose combination antimicrobial therapy. Despite a high prevalence of severe CF variants, lung function has been among the best in Europe. In this review, the Danish approach to management of CF prior to the introduction of new CF modulator treatment is explained and benchmarked. Downsides to the Danish approach are discussed and include increased burden of treatment, risk of antimicrobial resistance, side-effects and costs.

BACKGROUND: The recommendation of breastfeeding avoidance for women living with HIV in high-income settings may be influenced by cultural beliefs and come at an emotional cost. This multicenter, longitudinal, convergent mixed methods study aimed to compare differences in attitudes, concerns, and experiences surrounding breastfeeding in women living with HIV of Nordic and non-Nordic origin. SETTING: High-income setting. METHODS: Pregnant women living with HIV in the Nordic countries Denmark, Finland, and Sweden were recruited in 2019-2020. Quantitative data on attitudes surrounding infant feeding were assessed using the Positive Attitudes Concerning Infant Feeding questionnaire completed in the third trimester (T1), and 3 (T2) and 6 (T3) months postpartum. Women who completed the survey were also invited to participate in semistructured interviews at T1 and T3. The findings from the quantitative survey and qualitative interviews were brought together through merging to assess for concordance, complementarity, expansion, or discordance between the data sets and to draw metainferences. RESULTS: In total, 44 women completed the survey, of whom 31 also participated in qualitative interviews. The merged analyses identified three overarching domains representing commonalities across the quantitative and qualitative data: emotional impact, justifying not breastfeeding, and coping strategies. Not being able to breastfeed was emotionally challenging. Cultural expectations influenced the women's experiences and the strategies they used to justify their infant feeding choice. CONCLUSIONS: For women living with HIV in Nordic countries not breastfeeding was a complex, multilayered process substantially influenced by social and cultural expectations.

OBJECTIVE: To compare the consumption of antibiotics (AB), systemic steroids, and inhaled bronchodilators/glucocorticoids in the 3 years preceding the diagnosis of common variable immunodeficiency (CVID) among CVID patients and matched controls and to estimate whether the level of consumption was associated with the risk of a subsequent CVID diagnosis. METHODS: We conducted a nested case-control study, identifying all individuals (n=130 cases) diagnosed with CVID in Denmark (1994-2014) and 45 age- and sex-matched population controls per case (n=5850 controls) from national registers. Drug consumption was estimated as defined daily doses per person-year. We used conditional logistic regression to compute odds ratios and 95% confidence intervals. RESULTS: In the 3 years preceding a CVID diagnosis, we observed more frequent and higher consumption of all three drug classes. The association between consumption and risk of subsequent CVID diagnosis was statistically significant for all drug classes. The association was stronger with higher consumption and shorter time to CVID diagnosis. The fraction of cases compared to the controls redeeming ≥1 prescription of the included drugs during the study period was higher for AB (97% vs 52%), systemic steroids (35% vs 7.4%), and inhaled bronchodilators/glucocorticoids (46% vs 11.7%) (p<0.001). CONCLUSION: CVID patients have significantly higher use of AB, systemic steroids, and inhaled bronchodilators/glucocorticoids in the 3 years preceding CVID diagnosis than controls. Prescribing these drugs in primary healthcare could be an opportunity to consider (proactive) screening for CVID. Further studies are needed to identify optimal prescription cutoffs that could endorse its inclusion in public health policies.

This nationwide registry-based cohort study aimed to compare the risk of psychiatric diagnoses among HIV-exposed uninfected (HEU) children with a matched comparison group of HIV-unexposed uninfected (HUU) children, born in Denmark. We hypothesized that HEU children had an increased risk of psychiatric diagnoses and that this increased risk may differ by sex and age. All HEU children born in Denmark between year 2000 and 2020 were included. Each HEU child was matched by year of birth, maternal age at birth, and maternal immigration status to 10 HUU children. The primary outcome was risk of any psychiatric diagnosis (International Classification of Diseases, 10th Revision F00-F99). Incidence rate ratios (IRRs) were estimated using Poisson regression. Analyses stratifying by sex and age were also conducted. In total, 550 HEU children and 5500 HUU children were included. HEU children had an increased risk of any psychiatric disorder [IRR 1.45; 95% confidence interval (CI): 1.04-2.04] in the unadjusted analysis, but in the adjusted analysis, the risk was only significant for children aged 6-11 years [adjusted incidence rate ratio (aIRR) 1.93; 95% CI: 1.14-3.28]. Stratifying by sex, girls aged 6-11 years had an increased risk of any psychiatric disorder (aIRR 3.04; 95% CI: 1.27-7.28), while boys had an increased risk at age 12-20 years (aIRR 2.47; 95% CI: 1.18-5.17). In conclusion, HEU girls aged 6-11 years and HEU boys aged 12-20 years had an increased risk of any psychiatric disorder compared with HUU girls and boys, respectively. These findings highlight the importance of addressing the mental health needs of HEU children/adolescents.

PURPOSE: Delayed diagnosis of common variable immunodeficiency (CVID) remains a serious problem. We investigated whether some diseases diagnosed during out-patient visits or admission to hospitals could act as indicator conditions for CVID diagnosis. METHODS: In this nested case-control study, we identified 128 cases diagnosed with CVID in Denmark (1999-2013) and 640 age-, gender-, and region-matched controls. We obtained data on diseases diagnosed at hospitals in the five years before CVID diagnosis from The National Hospital Registry. We grouped hospital diagnoses in 33 major disease categories and 210 subcategories. We used conditional logistic regression to calculate the odds ratios (OR) and 95% confidence intervals (CI) to estimate associations between disease exposure and subsequent CVID. RESULTS: During the five years preceding a CVID diagnosis, cases had four times as many hospital contacts as the controls (p < 0.001). A diagnosis in 18 major disease categories showed a significant OR for subsequent diagnosis of CVID. The most substantial association with a subsequent CVID diagnosis was a diagnosis of lower respiratory tract infections (OR: 29.9; 95% CI: 14.2-63.2) and lung diseases (35.1; 15.0-82.5). We observed a similar association when we removed the last year before diagnosis from analysis and overall, in the years < 1, ≥ 1-3, and ≥ 3-5 before diagnosis, although the absolute number of exposures was small. Twenty-eight specific diseases displayed an at least 3-fold risk of subsequent CVID diagnosis. CONCLUSION: Targeted screening for antibody deficiency in patients diagnosed with specific diseases associated with CVID may lead to earlier CVID diagnosis and treatment and thereby potentially reduced morbidity and mortality.

Ceftolozane-tazobactam is a new ß-lactam/ß-lactamase inhibitor combination approved by the U.S. Food and Drug Administration in 2019 for the treatment of hospital-acquired and ventilator-associated pneumonia. The combination is a particularly potent inhibitor of penicillin-binding proteins with higher affinity than other ß-lactam agents. Persons with cystic fibrosis (pwCF) often harbour resistant Gram-negative bacteria in the airways and need antibiotics to prevent declining lung function. To test whether the introduction of ceftolozane-tazobactam in the period 2015-2020 led to a bacterial population level increase in cephalosporin resistance in a Danish CF population. In vitro, activity of ceftolozane-tazobactam was evaluated by susceptibility testing of clinical Pseudomonas aeruginosa isolated from pwCF from January 1, 2015, to June 1, 2020. Six thousand three hundred thirty two isolates collected from 210 adult pwCF were included. Thirty pwCF were treated with ceftolozane-tazobactam at least once. Ceftolozane-tazobactam exposure did not increase cephalosporin resistance on an individual or population level. However, resistance to ceftolozane-tazobactam was recorded despite no prior exposure in four pwCF. Compared to ceftazidime, ceftolozane-tazobactam had a better in vitro activity on P. aeruginosa. The percentage of non-mucoid P. aeruginosa isolates susceptible to ceftolozane-tazobactam were higher or equal to 5 other ß-lactams. Ceftolozane-tazobactam expands the armamentaria against P. aeruginosa with acceptable levels for a selection of drug resistance.

Norovirus is generally an acute infection causing symptoms such as diarrhea, nausea, and vomiting lasting for 24-48 hours. However, for immunocompromised patients, norovirus gastroenteritis can last for several years and result in villous atrophy and lead to severe malnutrition, dehydration, electrolyte imbalance and continuous viral shedding. Several treatment strategies have been suggested in case reports: nitazoxanide, ribavirin and enterally administered immunoglobulin with varying results. Favipiravir is also suggested but not tested on humans, highlighting the need for further research.

OBJECTIVES: To investigate psychosocial, sexual, reproductive and menopausal health in women with HIV (WWH) compared to women without HIV (WWOH) in Denmark. DESIGN: A nationwide cross-sectional study. METHODS: Data was retrieved from the SHARE study , a Danish nationwide cross-sectional survey examining psychosocial, sexual and reproductive health in people with HIV. Data from WWH, collected in 2021-2022, was matched 1:10 on age to a comparison group of WWOH from the nationally representative cohort study Project SEXUS . Associations between HIV status and psychosocial and sexual health outcomes were assessed by adjusted odds ratios (aOR) with 95% confidence intervals (95% CIs) obtained in logistic regression analyses controlling for potential confounding variables. The severity of menopausal symptoms in WWH was compared to published reference norms. RESULTS: Among 144 WWH and 1440 WWOH, recurrent loneliness was significantly more common among WWH (aOR 2.22 [95% CI: 1.25-3.96]), and WWH had significantly fewer children and close friends (aOR 0.52 [95% CI: 0.28-0.96] for 3-9 vs. 0-2 close friends). Symptoms of anxiety and depression did not differ between groups. Lack of sexual desire (aOR 2.90 [95% CI: 1.29-6.50]), low FSFI-6 score indicating sexual dysfunction (aOR 3.40 [95% CI: 1.33-8.69]), lubrication dysfunction (aOR 8.24 [95% CI: 2.83-24.00]) and genital pain dysfunction (aOR 5.13 [95% CI: 1.26-20.86]) were significantly more common in WWH compared to WWOH. No differences were seen in menopausal characteristics. CONCLUSIONS: WWH in Denmark have fewer children and close friends, and more often report recurrent loneliness, lacking sexual desire and sexual dysfunction compared to WWOH. No differences were evident in menopausal characteristics.

We describe the first case of infection with Helicobacter trogontum in a patient with X-linked agammaglobulinemia. A 22-year-old male with X-linked agammaglobulinemia presented with fever, malaise and a painful skin lesion on the lower left extremity. Spiral shaped Gram-negative rods were isolated from blood cultures and later identified as Helicobacter trogontum. The patient was treated with various intravenous and oral antibiotic regimens over a period of 10 months, each causing seemingly full clinical and paraclinical remission, yet several episodes of relapse occurred after cessation of antibiotic treatment. The review of the literature showed that only a few cases of infections with enterohepatic helicobacters belonging to the Flexispira rappini taxons have previously been reported. The majority of cases included patients with X-linked agammaglobulinemia and the symptomatology and course of disease were similar to the case described here. Infections with enterohepatic helicobacters, including Helicobacter trogontum, should be considered in patients with X-linked agammaglobulinemia presenting with fever, malaise and skin lesions. Careful cultivation and microbiological investigation are essential to determine the diagnosis and a long treatment period of over 6 months must be expected for successful eradication.
RESUMEN
Background: Long-term follow-up studies of COVID-19 olfactory and gustatory disorders (OGDs) are scarce. OGD, parosmia, and dysgeusia affect health-related quality of life (HRQoL) and the ability to detect potential hazards. Methods: In this study, 29 patients reporting OGD 1 month after severe-to-critical COVID-19 were tested at 3-6 months and retested at 12 months in case of hyposmia/anosmia. We used Sniffin Sticks Threshold, Discrimination, and Identification (TDI) test, Sniffin Sticks Identification Test (SIT16), Brief Smell Identification Test (BSIT), taste strips, and HRQoL. The patients were part of the prospective SECURe cohort. Results: Overall, 28% OD (TDI), 12% GD, 24% parosmia, and 24% dysgeusia (questionnaire) at 3-6 months (n = 29) and 28% OD (TDI), 38% parosmia, and 25% dysgeusia (questionnaire) at 12 months (n = 8) were observed. OGD decreased HRQoL: For 13%, it had a negative effect on daily life and, for 17%, it affected nutrition, 17% reported decreased mood, and 87-90% felt unable to navigate everyday life using their sense of smell and taste. A comparison of SIT16 and BSIT to TDI found sensitivity/specificity values of 75%/100% and 88%/86%. Conclusions: This is the first study to examine TDI, SIT16, BSIT, taste strips, and HRQoL up to 1 year after severe-to-critical COVID-19. The patients suffering from prolonged OGD, parosmia, and dysgeusia experienced severely decreasing HRQoL. We recommend including ear-nose-throat specialists in multidisciplinary post-COVID clinics.
RESUMEN
INTRODUCTION: Viral load measurement is an important gold standard for monitoring anti-retroviral treatment among people living with human immunodeficiency virus. The optimal use of the viral load results for guiding antiretroviral therapy depends on timely availability of the results at the clinic. The objective of the current study was to evaluate the turnaround time and utilization of viral load results in the clinical decision process. METHODOLOGY: This was a retrospective cohort study which involved patients receiving cART from 1 August 2018 to 31 January 2017 at three clinics in Tanzania. Data was extracted from patient files at the clinics and relevant records were kept at the viral load determining laboratory. The data were analysed with the Statistical Package for Social Sciences version 20. RESULTS: 445 subjects had a viral load in test results and 88% had a viral load of > 1,000 copies/mL. The median duration on the current regimen was five years. Median time between the clinics receiving the results and communicating them to the patients was 40 days. Shorter turnaround time was observed for patients with virological failure (p = 0.003). A higher prevalence of virological failure was found in patients monitored at the Kilimanjaro Christian Medical Centre (KCMC) compared to the two primary health clinics (p = 0.04). CONCLUSIONS: The median viral load turnaround time was longer than stipulated by the national Tanzanian guidelines. Interventions that may reduce viral load turn-around-time, including point of care viral load testing, are needed to optimise monitoring of anti-retroviral therapy.

A large proportion of patients exhibit persistently reduced pulmonary diffusion capacity after COVID-19. It is unknown whether this is due to a post-COVID restrictive lung disease and/or pulmonary vascular disease. The aim of the current study was to investigate the association between initial COVID-19 severity and haemoglobin-corrected diffusion capacity to carbon monoxide (DLco) reduction at follow-up. Furthermore, to analyse if DLco reduction could be linked to pulmonary fibrosis (PF) and/or thromboembolic disease within the first months after the illness, a total of 67 patients diagnosed with COVID-19 from March to December 2020 were included across three severity groups: 12 not admitted to hospital (Group I), 40 admitted to hospital without intensive care unit (ICU) admission (Group II), and 15 admitted to hospital with ICU admission (Group III). At first follow-up, 5 months post SARS-CoV-2 positive testing/4 months after discharge, lung function testing, including DLco, high-resolution CT chest scan (HRCT) and ventilation-perfusion (VQ) single photon emission computed tomography (SPECT)/CT were conducted. DLco was reduced in 42% of the patients; the prevalence and extent depended on the clinical severity group and was typically observed as part of a restrictive pattern with reduced total lung capacity. Reduced DLco was associated with the extent of ground-glass opacification and signs of PF on HRCT, but not with mismatched perfusion defects on VQ SPECT/CT. The severity-dependent decline in DLco observed early after COVID-19 appears to be caused by restrictive and not pulmonary vascular disease.
RESUMEN
The risk of severe adult respiratory coronavirus-2 (SARS-CoV-2) infection and the course of the infection among individuals with common variable immunodeficiency (CVID) relative to the general population have been a matter of debate. We conducted a Danish nationwide study comparing the timing of SARS-CoV-2 vaccination, the risk of first confirmed SARS-CoV-2 infection, re-infection, and the outcome of infection among individuals with CVID relative to an age- and gender matched control group. Cox regression was used to calculate incidence rate ratios. The CVID patients received SARS-CoV-2 vaccinations earlier than those included in the population control group. Even so, the risks of both first infection and re-infection were increased among the individuals with CVID. The CVID group also had increased risk for hospital contacts due to SARS-CoV-2 infection relative to the general population. However, reassuringly, the risk of mechanical ventilation and death did not differ between the groups, but the numbers were low in both groups, making the estimates uncertain. Though this is the largest study to investigate the risk of SARS-CoV-2 infections and outcomes hereof among individuals with CVID relative to the general population, we cannot rule out minor differences in severity, which might only be detectable with an even larger sample size.
