Persistence and adherence in multiple sclerosis patients starting glatiramer acetate treatment: assessment of relationship with care received from multiple disciplines.

BACKGROUND: In multiple sclerosis patients, the persistence of, and adherence to, disease-modifying treatment are often insufficient. The degree of persistence and adherence may relate to the care received from various disciplines. METHODS: In an observational study of 203 patients treated with glatiramer acetate 20 mg subcutaneous daily, we assess the persistence and adherence in relation to the amount of care received in various disciplines. The frequencies and durations of care per discipline were reported by patients online, as were missed doses and eventual treatment discontinuation. The associations between the care provided by neurologists, nurses, psychologists, pharmacists, and rehabilitative doctors and persistence and adherence were the primary outcomes; the associations between care received from general practitioners, occupational therapists, physiotherapists, social workers, dieticians, home caregivers, informal caregivers, other medical specialists, and other caregivers and persistence and adherence were secondary outcomes. RESULTS: It was found that the 12-month persistence rate was 62% and that 85% of the persistent patients were 95% adherent (missed <5% of doses). Patients who discontinued treatment in the fourth quarter (Q) had received less-frequent and shorter psychological care in Q3 than persistent patients (P=0.0018 and P=0.0022). Adherent patients had received more frequent home care and informal care than nonadherent patients (P=0.0074 and P=0.0198), as well as longer home care and informal care (P=0.0074 and P=0.0318). Associations between care in other disciplines and persistence or adherence were not observed. As to the relationship between adherence and persistence, nonadherence in Q2 was related to discontinuation after Q2 (P=0.0001). CONCLUSION: We obtained no evidence that, in multiple sclerosis patients, persistence of and adherence to disease-modifying treatment are associated with the amount of neurological, nursing, pharmaceutical, or rehabilitative care. However, findings suggest that the treatment of psychological problems in Q3 may relate to persistence and that home care and informal care may relate to adherence.

The interactive web-based program MSmonitor for self-management and multidisciplinary care in multiple sclerosis: utilization and valuation by patients.

BACKGROUND: MSmonitor is an interactive web-based program for self-management and integrated, multidisciplinary care in multiple sclerosis. METHODS: To assess the utilization and valuation by persons with multiple sclerosis, we held an online survey among those who had used the program for at least 1 year. We evaluated the utilization and meaningfulness of the program's elements, perceived use of data by neurologists and nurses, and appreciation of care, self-management, and satisfaction. RESULTS: Fifty-five persons completed the questionnaire (estimated response rate 40%). The Multiple Sclerosis Impact Profile (MSIP), Medication and Adherence Inventory, Activities Diary, and electronic consultation (e-consult) were used by 40%, 55%, 47%, and 44% of respondents and were considered meaningful by 83%, 81%, 54%, and 88%, respectively. During out-patient consultations, nurses reportedly used the MSmonitor data three to six times more frequently than neurologists. As to nursing care, more symptoms were dealt with (according to 54% of respondents), symptoms were better discussed (69%), and the overall quality of care had improved (60%) since the use of the program. As to neurological care, these figures were 24%, 31%, and 27%, respectively. In 46% of the respondents, the insight into their symptoms and disabilities had increased since the use of the program; the MSIP, Activities Diary, and e-consult had contributed most to this improvement. The overall satisfaction with the program was 3.5 out of 5, and 73% of the respondents would recommend the program to other persons with multiple sclerosis. CONCLUSION: A survey among persons with multiple sclerosis using the MSmonitor program showed that the MSIP, Medication and Adherence Inventory, Activities Diary, and e-consult were frequently used and that the MSIP, Medication and Adherence Inventory, and e-consult were appreciated the most. Moreover, the quality of nursing care, but not so neurological care, had improved, which may relate to nurses making more frequent use of the MSmonitor data than neurologists.

The interactive web-based program MSmonitor for self-management and multidisciplinary care in multiple sclerosis: concept, content, and pilot results.

BACKGROUND: There is a growing need to offer persons with multiple sclerosis (PwMS) possibilities for self-management and to integrate multidisciplinary health data. In 2009-2014 we developed a patient-reported outcome based, interactive, web-based program (MSmonitor) for (self-)monitoring, self-management and integrated, multidisciplinary care in MS. METHODS: The notions underlying the MSmonitor concept and the program's elements are described. We analyze MSmonitor's role in the self-management of fatigue by retrospective comparison of fatigue and health-related quality of life (HRQoL) before and after usage of specific elements of MSmonitor, and by a correlative analysis between frequency of usage and fatigue change. RESULTS: After a step-wise development the program comprises six validated questionnaires: Multiple Sclerosis Impact Profile, Modified Fatigue Impact Scale-5 items (MFIS-5), Hospital Anxiety and Depression Scale, Multiple Sclerosis Quality of Life-54 items, and the 8-item Leeds Multiple Sclerosis Quality of Life (LMSQoL) questionnaires; two inventories: Medication and Adherence Inventory, Miction Inventory; two diaries: Activities Diary, Miction Diary; and two functionalities: e-consult and personal e-logbook. The program is now used in 17 hospitals by 581 PwMS and their neurologists, MS nurses, physical therapists, rehabilitative doctors, continence nurses, and family doctors. Those PwMS (N=105) who used the LMSQoL and MFIS-5 questionnaires at least twice in a period of up to 6 months, showed improved HRQoL (P<0.026). In the subgroup (N=56) who had also used the Activities Diary twice or more, the frequency of diary usage correlated modestly with the degree of fatigue improvement (r=0.292; P=0.028). CONCLUSION: MSmonitor is an interactive web-based program for self-management and integrated care in PwMS. Pilot data suggest that the repeated use of the short MFIS-5 and LMSQoL questionnaires is associated with an increase in HRQoL, and that a repeated use of the Activities Diary might contribute to the self-management of fatigue.

Reversible posterior leukoencephalopathy syndrome during sunitinib therapy for metastatic renal cell carcinoma.

Sunitinib is an oral receptor tyrosine kinase inhibitor with potent antiangiogenic and antitumor activity that is approved for the treatment of advanced renal cell carcinoma (RCC), malignant gastrointestinal stromal tumors and pancreatic neuroendocrine tumors. Well-known side effects of sunitinib include hypertension, fatigue, thyroid dysfunction, cardiotoxicity, gastrointestinal toxicity and skin toxicity. In this study, we report the case of a 61-year-old male with papillary metastatic RCC who responded to sunitinib but developed generalized tonic-clonic seizures during the third cycle. Magnetic resonance imaging (MRI) was compatible with reversible posterior leukoencephalopathy syndrome (RPLS). After the administration of anti-epileptic drugs and the withdrawal of sunitinib there was rapid clinical improvement. Notably, radiological characteristics of RPLS persisted during second-line therapy with the mammalian target of rapamycin (mTOR) inhibitor everolimus and only resolved when everolimus was terminated due to disease progression. Although sunitinib-induced RPLS has been reported previously, our case is the first to additionally suggest that everolimus may sustain and therefore potentially contribute to the occurrence of RPLS.

[A man in a coma after varices bleeding]. / Een man in coma na een varicesbloeding.

We admitted a 43-year-old comatose man with known liver cirrhosis and hyperintense subarachnoid spaces on brain CT, suggestive of subarachnoid hemorrhage. He died shortly thereafter. Autopsy did not show signs of subarachnoid hemorrhage, but revealed extensive cerebral edema. Pseudo-subarachnoid hemorrhage due to metabolic disturbances was diagnosed.

Correlating nerve conduction studies and clinical outcome measures on carpal tunnel syndrome: lessons from a randomized controlled trial.

The reported relationships between nerve conduction studies (NCS) and outcome measures in carpal tunnel syndrome (CTS) are weak to moderate. However, selection of patients may have confounded nonrandomized studies. NCS have potentially great value in selecting patients for a specific treatment and in objectively assessing the efficacy of treatments in CTS, especially if they correlate significantly with clinical outcome measures. To investigate the relationship between clinical outcome measures for the severity of complaints and NCS in patients treated for CTS, data were obtained from a multicenter randomized controlled trial on the efficacy of splinting versus surgery for CTS. At baseline and 12 months after randomization, clinical outcome measures were assessed and NCS were performed. In total, 138 patients completed the questionnaires and underwent repeated NCS. Relationships were analyzed with Spearman rank correlation coefficients and Pearson correlation coefficients. All NCS parameters showed highly significant improvement compared with baseline (P < 0.001). Modest correlations (< 0.4) were found between the neurophysiologic and clinical outcome measures after 12 months, and between the changes in these different categories of outcome measures. This study confirms that the parameters of NCS improve significantly after treatment for CTS, but the modest correlations between neurophysiologic and clinical outcome measures do not support that NCS are routinely performed in clinical practice to evaluate treatment effects. However, studies investigating the effects of treatment for CTS should incorporate both clinical outcome measures and NCS, because they are complementary. Furthermore, NCS can provide additional information to the clinician when treatment effects are unsatisfactory.

Gender-related association between the TGFB1+869 polymorphism and multiple sclerosis.

Our objective was to investigate whether polymorphisms and haplotypes in the TGFB1 gene are associated with susceptibility or disease characteristics of multiple sclerosis (MS). In 247 MS patients and 194 controls, single nucleotide polymorphisms (SNPs) at position +869 (Leu10Pro) and position +915 (Arg25Pro) in the signaling sequence of the TGFB1 gene were determined, and the distribution of alleles, genotypes, and haplotypes was related to clinical data. In addition, magnetic resonance imaging (MRI) data were studied in a subgroup of patients (n = 96). The allele distribution of the two polymorphisms studied was in Hardy-Weinberg equilibrium in patients and in controls. No association was found with any of the three haplotypes found in the Dutch population, denoted as haplotype 1 (TGFB1+869T-TGFB1+915G), haplotype 2 (TGFB1+869C-TGFB1+915G), and haplotype 3 (TGFB1+869C-TGFB1+915C). However, the TGFB1+869 genotype CC was significantly more frequent in patients (p = 0.031, chi2 test). The highest frequency of the TGFB1+869 genotype CC was observed in male patients (25.2% vs. 10.0% in controls, p = 0.004, chi2 test), and carriership of TGFB1+869 allele C was correspondingly increased in male patients (74.8% vs. 56.7%, p = 0.008, chi2 test, OR 2.27, 95% CI 1.23-4.17). Although there was no association with clinical markers of disease progression, patients homozygous for TGFB1+869 allele C showed a significantly higher annual increase in two MRI parameters: ventricular fraction (central atrophy) and T1-hypointense lesion load (matrix destruction). The TGFB1 T+869C (Leu10Pro) gene polymorphism is associated with MS susceptibility, especially in males, and with a more destructive course of the disease as illustrated by MRI.

The interleukin-1 gene family in multiple sclerosis susceptibility and disease course.

Multiple sclerosis (MS) is a chronic disease of presumed autoimmune origin with a considerable polygenic influence. We have previously observed that a specific allele combination in genes of the interleukin-1 (IL-1) family influenced the progression rate in MS. We have considerably expanded our patient population (492 MS patients and 228 controls). In the present study, we investigated the role of the IL-IA--889, IL-1B--511, IL-1B f3953 and IL-1RN VNTR gene polymorphisms in MS. In addition, we performed preliminary analyses on longitudinal magnetic resonance imaging (MRI) data. We found no associations between the polymorphisms and susceptibility to MS or clinical features. In addition, we observed no significant effect of the polymorphisms on brain or lesion volumes, Based on our data and those from the literature, one can conclude that there is currently no evidence to support a role for the IL-1 genes in MS.

Interleukin (IL)-1 gene polymorphisms: relevance of disease severity associated alleles with IL-1beta and IL-1ra production in multiple sclerosis.

BACKGROUND: Multiple sclerosis (MS) is an autoimmune disorder, with a considerable genetic influence on susceptibility and disease course. Cytokines play an important role in MS pathophysiology, and genes encoding various cytokines are logical candidates to assess possible associations with MS susceptibility and disease course. We previously reported an association of a combination of polymorphisms in the interleukin (IL)-1B and IL-1 receptor antagonist (IL-1RN) genes (i.e. IL-1RN allele 2+/IL-1B(+3959)allele 2-) with disease severity in MS. Extending this observation, we investigated whether IL-1beta and IL-1ra production differed depending on carriership of this gene combination. METHODS: Twenty MS patients and 20 controls were selected based upon carriership of the specific combination. In whole blood, in vitro IL-1beta and IL-1ra production was determined by enzyme-linked immunosorbent-assay after 6 and 24 h of stimulation with lipopolysaccharide. RESULTS: Carriers of the specific combination produced more IL-1ra, especially in MS patients, although not significantly. IL-1ra production was significantly higher in individuals homozygous for IL-1RN allele 2. In patients, Il-1ra production was higher and IL-1beta production lower compared with controls. In primary progressive patients, the IL-1beta /IL-1ra ratio was significantly lower than in relapsing-remitting patients. CONCLUSION: Our results suggest higher in vitro IL-1ra production in carriers of IL-1RN allele 2, with an indication of an allelic dose-effect relationship.
