Project description:The risk of developing severe complications from an influenza virus infection is increased in patients with chronic inflammatory diseases such as psoriasis (PsO) and atopic dermatitis (AD). However, low influenza vaccination rates have been reported. The aim of this study was to determine vaccination rates in PsO compared to AD patients and explore patient perceptions of vaccination. A multicenter cross-sectional study was performed in 327 and 98 adult patients with PsO and AD, respectively. Data on vaccination, patient and disease characteristics, comorbidity, and patient perceptions was collected with a questionnaire. Medical records and vaccination certificates were reviewed. A total of 49.8% of PsO and 32.7% of AD patients were vaccinated at some point, while in season 2018/2019, 30.9% and 13.3% received an influenza vaccination, respectively. There were 96.6% and 77.6% of PsO and AD patients who had an indication for influenza vaccination due to age, immunosuppressive therapy, comorbidity, occupation, and/or pregnancy. Multivariate regression analysis revealed higher age (p < 0.001) and a history of bronchitis (p = 0.023) as significant predictors of influenza vaccination in PsO patients. Considering that most patients had an indication for influenza vaccination, the rate of vaccinated patients was inadequately low.

Project description:IntroductionPsoriasis is a systemic inflammatory disease characterised by pruritic skin lesions that impair quality of life (QOL). Long-Term Documentation of the Utilization of Apremilast in Patients with Plaque Psoriasis under Routine Conditions (LAPIS-PSO; ClinicalTrials.gov: NCT02626793) was a 52-week, prospective, multicentre, observational cohort study conducted in real-world dermatology clinical settings in Germany. We evaluated physician- and patient-reported outcomes for QOL, effectiveness and tolerability in patients with moderate to severe psoriasis vulgaris in LAPIS-PSO.MethodsThe primary endpoint was the percentage of patients achieving Dermatology Life Quality Index (DLQI) score ≤ 5 or ≥ 5-point improvement from baseline in DLQI score at visit 2 (~ 4 months after baseline). Secondary endpoints included assessments of symptoms and disease severity. Tolerability was evaluated based on adverse events (AEs). A pre-defined subgroup analysis based on baseline Physician's Global Assessment (PGA) score (2 or 3 versus 4) was performed. Data were examined descriptively through visit 5 (~ 13 months) using the last-observation-carried-forward (LOCF) approach and data as observed.ResultsIn total, 257 patients were included for efficacy assessment. On LOCF analysis, most patients achieved the primary endpoint at visit 2 (66.5%); DLQI response was maintained at visit 5 (72.4%). Earlier treatment response was observed in patients with a PGA score of 2 or 3 versus 4 (visit 1 PASI ≤ 3: 20.5% versus 10.8%). Adverse events were consistent with the known safety profile of apremilast.ConclusionsIn routine clinical care in Germany, patients with moderate to severe plaque psoriasis benefited from apremilast treatment up to ~ 13 months, consistent with findings from clinical trials, with a good safety profile.

Project description:BackgroundThe German Committee on Vaccination recommends pneumococcal vaccination for infants, seniors 60+ years and patients at risk with defined underlying diseases. Aim of this study was to assess the pneumococcal vaccination rate (pnc-VR) in patients with certain incident inherited or acquired immunodeficiency or immunosuppression and to understand who vaccinates these patients who are particularly at high risk to develop a pneumococcal infection.MethodsWe conducted a cohort study in patients aged 2 years or older, with a first episode of a "high-risk" condition between January 2013 and December 2014 based on a representative sample of German claims data. Pnc-VR was calculated as the proportion of patients receiving any pneumococcal vaccine within two years after first episode of "high-risk" condition. Further analyses cover pnc-VR stratified by high risk conditions and region, time to vaccination, and physician specialty administering the pneumococcal vaccination.ResultsThe study population comprised 204,088 incident "high-risk" patients (56% female). The overall pnc-VR within two years was 4.4% (95%-confidence interval: 4.3%-4.5%). Within specific high-risk conditions, we found the highest vaccination rate of 11.5% (10.1%-13.0%) among patients starting immunosuppressants with underlying rheumatoid arthritis followed by 9.9% (7.8%-12.4%) in HIV patients. Stratification by region revealed a slightly higher vaccination rate in Eastern (6.5%: 6.0%-6.9%) compared to Western Germany (4.2%: 4.1-4.3%). Median time to vaccination within the first two years in vaccinated patients was 332.5 days (Q1 142 days, Q3 528 days). The majority of patients (92.6%) got vaccinated by a general practitioner.ConclusionAlthough these vulnerable patients need protection most, our study suggests that the overall pnc-VR after a first episode of a high-risk condition for pneumococcal disease is very low and vaccination is far too late. To prevent pneumococcal disease in patients at high risk, further efforts are needed to increase awareness and improve the timeliness of pneumococcal vaccination.

Project description:BackgroundInvasive (IPD, defined as detection of pneumococci in sterile body fluids like meningitis or bacteremic pneumonia) and non-invasive Streptococcus pneumoniae infections (i.e. non-bacteremic pneumonia, otitis media) in adults are associated with substantial morbidity, mortality and costs. In Germany, Pneumococcal polysaccharide vaccination (PPV23) is recommended for all persons >60 years and for defined risk groups (age 5-59). The aim of this model was to estimate the potential cost-effectiveness and benefit-cost ratios of the adult vaccination program (18 years and older), considering the launch of the pneumococcal conjugate vaccine for adults (PCV13).MethodsA cross-sectional steady state Markov model was developed to estimate the outcomes of PCV13, PPV23 vaccination schemes and 'no vaccination'. Conservative assumptions were made if no data were available for PCV13 and PPV23 respectively. The effectiveness of individual pneumococcal vaccination in adults was adjusted for expected indirect effects due to the vaccination in infants. Data on incidences, effectiveness and costs were derived from scientific literature and publicly available databases. All resources used are indicated. Benefit-cost ratios and cost-effectiveness were evaluated from the perspective of the German Statutory Health Insurance as well as from social perspective.ResultsUnder the assumption that PCV13 has a comparable effectiveness to PCV7, a vaccination program with PCV13 revealed the potential to avoid a greater number of yearly cases and deaths in IPD and pneumonia in Germany compared to PPV23. For PCV13, the costs were shown to be overcompensated by monetary savings resulting from reduction in the use of health care services. These results would render the switch from PPV23 to PCV13 as a dominant strategy compared to PPV23 and 'no vaccination'. Given the correctness of the underlying assumptions every Euro spent on the PCV13 vaccination scheme yields savings of 2.09 € (social perspective: 2.16 €) compared to PPV23 and 1.27 € (social perspective: 1.32 €) compared to 'no vaccination', respectively.ConclusionsResults of the model indicate that the health economic benefit of immunizing adults with PCV13 can be expected to outperform the sole use of PPV23, if the effectiveness of PCV13 is comparable to the effectiveness of PCV7.

Project description:This study describes the effects of the introduction of universal infant pneumococcal conjugate vaccination in 2006 on invasive pneumococcal disease (IPD) among children and adults in Germany with a focus on the dynamics of serotype distribution in vaccinated and non-vaccinated age groups. Over a period of 22 years (1992-2014), microbiological diagnostic laboratories from all over Germany have been sending isolates of IPD cases to the German National Reference Center for Streptococci on a voluntary basis. Streptococcus pneumoniae isolates were serotyped using Neufeld's Quellung method. Among children <16 years, the proportion of PCV7 serotypes among isolates from IPD cases decreased from 61.8% before vaccination (1997-2006) to 23.5% in the early vaccination period (2007-2010; p = 1.30E-72) and sank further to 5.2% in the late vaccination period (2010-2014; p = 4.59E-25). Similar reductions were seen for the separate age groups <2 years, 2-4 years and 5-15 years. Among adults, the proportion of PCV7 serotypes decreased from 43.4% in the pre-vaccination period (1992-2006) to 24.7% (p = 3.78E-88) in the early vaccination period and 8.2% (p = 5.97E-161) in the late vaccination period. Both among children and among adults, the non-PCV7 serotypes 1, 3, 7F and 19A significantly increased in the early vaccination period. After the switch from PCV7 to PVC10/PCV13 for infant vaccination in 2010, serotypes 1, 6A and 7F significantly decreased. A decrease in serotype 19A was only observed in 2013-2014, as compared to 2010-2011 (children p = 4.16E-04, adults p = 6.98E-06). Among adults, serotype 3, which strongly increased in the early vaccination period (p = 4.44E-15), remained at a constant proportion in the late vaccination period. The proportion of non-PCV13 vaccine serotypes increased over the whole vaccination period, with serotypes 10A, 12F, 23B, 24F and 38 most significantly increasing among children and serotypes 6C, 12F, 15A, 22F and 23B increasing among adults. Eight years of childhood pneumococcal conjugate vaccination have had a strong effect on the pneumococcal population in Germany, both among the target group for vaccination as well as among older children and adults.

Project description:INTRODUCTION:In Germany, a 23-valent polysaccharide pneumococcal vaccine (PPSV23) is recommended for elderly (60+) and patients 16+ with chronic diseases not associated with immune suppression. For all other patients at risk, sequential immunization with a 13-valent pneumococcal conjugate vaccine (PCV13) first, followed by PPSV23 is recommended. Repeated vaccination with PPSV23 is recommended every 6 years after individual assessment by the physician. This was adopted into the vaccination directive with binding reimbursement and funding. However, additional voluntary services allow statutory health insurances to differentiate from each other. Aim of this study is to estimate the cost-effectiveness of voluntary service scenarios compared to the strategy in place to support informed decision making. METHODS:A microsimulation framework with Markov-type process of a population susceptible to pneumococcal disease over a lifetime horizon was developed to compare effectiveness and cost-effectiveness of different vaccination strategies. We simulated 1,000 iterations for seven scenarios. Assumptions were derived from published literature and probabilistic sensitivity analysis was run to show the robustness of the model. RESULTS:Our study indicates that all voluntary service strategies could prevent further clinical cases compared to the existing policy. Depending on the scenario, 48-142 invasive pneumococcal disease (IPD), 24,000-45,000 hospitalized all-cause nonbacteremic pneumonia (NBP), 15,000-45,000 outpatient NBP cases, and 4,000-8,000 deaths could be avoided on average. This refers to potential savings of €115 Mio. - €187 Mio. for medical and non-medical costs. Additional costs per patient for the payer are €2.48 to €7.13 and for the society €2.20 to €6.85. The ICER per LYG ranged from €3,662 to €23,061 (payer) and €3,258 to €29,617 (societal). All but one scenario was cost-effective in ≥60% of the generated 1,000 simulations. CONCLUSION:Compared to the vaccination strategy in place, the different hypothetical scenarios can be considered cost-effective and suitable as additional voluntary services.

Project description:Psoriasis is a chronic inflammatory skin disease. The absence of microbial organisms as potential causal agents has given rise to the hypothesis that the inflammation is due to an autoimmune reaction. The defined inflamed areas of the skin lesions argue for an immunological disease with a local production of a causal antigen. Pso p27 is a protein generated in mast cells in psoriatic plaques, but not in uninvolved skin. We recently demonstrated that the Pso p27 is generated by cleavage of SerpinB3 (SCCA1) in the presence of mast cell associated chymase. In this communication we demonstrate by X-ray crystallographic analysis that the cleavage products associate into a complex similar to SCCA1, but with the reactive centre loop inserted into a 5-stranded central ?-sheet. Native gel electrophoresis show that these Pso p27 complexes form large aggregates which may be of significance with respect to an immunogenic role of Pso p27.

Project description:BackgroundThe utility of the Simplified Psoriasis Index (SPI), a recently developed multidomain tool for assessing psoriasis, was investigated in a study assessing response to secukinumab.MethodsIn an open-label, multicentre study involving 17 French centres, patients with moderate-to-severe plaque psoriasis received secukinumab 300 mg subcutaneously once weekly from baseline to W4, then every 4 weeks until W48. Dermatologist-scored SPI psoriasis severity (proSPI-s) was compared with Psoriasis Area and Severity Index (PASI). Patient self-assessed severity (saSPI-s) and psychosocial impact (SPI-p) were compared with PASI and Dermatology Life Quality Index (DLQI), respectively.ResultsWe included 120 patients (69.2% male; mean age 45.9 years; mean duration of psoriasis 21.6 years). Mean baseline scores were as follows: proSPI-s 24.9, saSPI-s 23.5, PASI 23.1, SPI-p 8.2 and DLQI 13.6. Severity scores achieved by 16 weeks (proSPI-s 2.3, saSPI-s 2.2 and PASI 2.2) were maintained to W52. Reductions in mean psychosocial impact scores were maintained to W52 (SPI-p and DLQI, respectively, 2.1 and 1.5 at W16; 1.5 and 1.9 at W52).ConclusionsDecrease of PASI scores in response to secukinumab was closely correlated with proSPI-s, supporting the latter's suitability for assessing response to therapy. Although the correlation between PASI and saSPI-s was slightly weaker, patients were able to complete a valid assessment of their psoriasis independently, and thus potentially remotely. With the added benefit of psychosocial impact assessment (SPI-p), SPI provides a valid tool enabling patients to assess their own psoriasis, remotely if necessary.

Project description:Patients with inflammatory bowel disease (IBD) will be assessed for immunologic response to pneumococcal vaccination. Patients with IBD meet criteria as outlined by the Centers for Disease Control (CDC) for pneumococcal vaccination, yet the investigators have found that pneumococcal vaccination in this population is under-utilized. It is unknown whether or not IBD or IBD-related medications impact the immune response to this recommended vaccine.
Three groups of 25 patients each will be recruited. The first group will consist of outpatients with IBD who are receiving infliximab (Remicade TM) while on concommitant immunosuppressive therapy (with either 6MP, azathioprine, or methotrexate). This group is intended to represent a common ‘heavily immunosuppressed’ patient group with IBD.
The second group will consist of patients with IBD seen in our outpatient clinic who are not on any immune-suppressive medications. These patients meet CDC criteria for vaccination by virtue of having a chronic medical illness. The third group will consist of healthy age-matched (to the first group) controls.
After obtaining informed consent, patients will be screened with baseline lab tests including testing for antibodies against pneumococcus. At the baseline visit, patients will also undergo a brief medical history, physical examination, and assessment of their IBD disease activity.
Included patients will then undergo a one-time intramuscular vaccination with 23-valent polysaccharide pneumococcal vaccine (Pneumovax TM). One month later, subjects will return for a blood draw to assess for response to pneumococcal vaccination.

Project description:BackgroundDespite recommendations from the German Standing Committee on Vaccination (STIKO), pneumococcal vaccination coverage remains low in vulnerable populations. This study estimated the pneumococcal vaccination coverage rate (VCR) and timing among individuals aged 16-59 years in Germany who were recommended to receive pneumococcal vaccination, according to STIKO.MethodsA retrospective cohort analysis was conducted using the German InGef database. Individuals aged 16 to 59 years diagnosed with at least one "at-risk" (chronic disease) or "high-risk" (e.g., immunocompromising) condition considered to be at-risk of pneumococcal infection were identified at the time of first diagnosis, between January 1, 2016 and December 31, 2018, and followed up until December 31, 2019. The percentage of cumulative pneumococcal VCR with 95% confidence interval (CI) was reported for each calendar year of follow-up.ResultsThere were 334,292 individuals followed for a median of 2.38 (interquartile range (IQR) 1.63-3.13) person years. For individuals aged 16-59 years diagnosed with an incident risk condition in 2016, pneumococcal VCR increased from 0.44% (95% CI 0.41-0.48) in 2016 to 1.24% (95% CI 1.18-1.30) in 2019. In 2019, VCRs were higher in individuals with high-risk conditions compared with at-risk conditions (2.24% (95% CI 2.09-2.40) vs. 0.90% (95% CI 0.85-0.96)). In 2019, VCRs were higher in individuals aged 50 to 59 years compared with individuals aged 16 to 49 years (2.25% (95% CI 2.10-2.41) vs. 0.90% (95% CI 0.84-0.96)). Similar trends were observed in individuals with newly diagnosed risk conditions identified in 2017 and in 2018. Older age, influenza vaccination and increasing number of risk conditions increased the likelihood of pneumococcal vaccination. Median time to vaccination from diagnosis of the risk condition was shorter for high-risk conditions (369.5 days (IQR 155.8-702.0)) compared to at-risk conditions (435.5 days (IQR 196.3-758.8)).ConclusionDespite recommendations from STIKO, pneumococcal vaccination coverage remains very low and with long delays in vulnerable individuals aged 16-59 in Germany. Further efforts are required to increase immunization levels and shorten time to vaccination among individuals 16-59 years of age developing conditions with higher susceptibility to pneumococcal infection.
