Early and late contrast enhancing lesions after photon radiotherapy for IDH mutated grade 2 diffuse glioma.

Objective: The interpretation of new enhancing lesions after radiotherapy for diffuse glioma remains a clinical challenge. We sought to characterize and classify new contrast enhancing lesions in a historical multicenter cohort of patients with IDH mutated grade 2 diffuse glioma treated with photon therapy.

Methods: We reviewed all follow-up MRI's of all patients treated with radiotherapy for histologically confirmed, IDH mutated diffuse grade 2 glioma between 1-1-2007 and 31-12-2018 in two tertiary referral centers.

Evaluation of image-guided and surface-guided radiotherapy for breast cancer patients treated in deep inspiration breath-hold: A single institution experience.

Introduction: Nowadays, deep inspiratory breath-hold is a common technique to reduce heart dose in left-sided breast radiotherapy. This study evaluates the evolution of the breath-hold technique in our institute, from portal imaging during dose delivery to continuous monitoring with surface-guided radiotherapy (SGRT).

Materials And Methods: Setup data and portal imaging results were analyzed for 98 patients treated before 2014, and SGRT data for 228 patients treated between 2018 and 2020.

Changes of ferritin and CRP levels in melanoma patients treated with adjuvant interferon-α (EORTC 18952) and prognostic value on treatment outcome.

Adjuvant therapy with interferon-α (IFN) only benefits a small subgroup of melanoma patients and a predictive marker selecting responders does not exist. IFN induces increased ferritin and decreased C-reactive protein (CRP) levels; however, an association with treatment effect was not studied. Serum was collected from patients participating in the European Organization for Research and Treatment of Cancer 18 952 trial comparing adjuvant treatment with IFN to observation.

Churg-Strauss Syndrome following PTU Treatment.

Propylthiouracil (PTU) is a frequently prescribed drug in the treatment of hyperthyroidism. The use of PTU is, however, accompanied by numerous potentially serious side effects including vasculitis. PTU-related vasculitides can present as haematuria, pulmonary haemorrhage, or cutaneous lesion together with aspecific symptoms such as fever, myalgia, arthralgia, and fatigue.

ANCA-Positive Patients: The Influence of PR3 and MPO Antibodies on Survival Rate and The Association with Clinical and Laboratory Characteristics.

Objectives: To compare the survival rate, and the clinical and laboratory characteristics in patients, characterized by the presence of certain anti-neutrophil cytoplasmic auto-antibodies (ANCAs).

Methods: In a retrospective observational study, we analyzed the data of all patients with a positive ANCA test between 1995 and 2005 at our hospital. Based on serology patients were divided in three subgroups (ANCA-Proteinase 3 (PR3), ANCA-Myeloperoxidase (MPO) and atypical ANCA), irrespective of the diagnosis.

[ANCA(antineutrophil cytoplasmic antibodies)-associated vasculitis in a man with extreme fatigue, fever and progressive renal dysfunction].

A 55-year-old man, with no previous history, presented with extreme fatigue and fever and was admitted to hospital. He had progressive renal dysfunction and his serum anti-neutrophil cytoplasmic antibodies (ANCA) were markedly elevated. Renal histology was consistent with ANCA-associated vasculitis.

Current causes of death in systemic lupus erythematosus in Europe, 2000--2004: relation to disease activity and damage accrual.

Current therapeutic and diagnostic resources have turned systemic lupus erythematosus (SLE) into a chronic disease by reducing mortality rates. The exact contribution of disease activity and disease related damage to mortality is not well studied. The aim of this study was to describe the current causes of death (COD) in a multinational European cohort of patients with SLE in relation to quantified measures of disease activity and damage.

[Progressive multifocal leukoencephalopathy in a patient following long-term immunosuppressive therapy for systemic lupus erythematosus].

A 41-year-old woman who had suffered from systemic lupus erythematosus (SLE) for 22 years presented with signs of neurological deficits. CT-scanning of the brain revealed hypodense lesions that suggested cerebral infarction due to vasculitis in SLE. However, in spite of intensified immunosuppressive therapy, she showed rapid neurological deterioration.

Profiles of the acute-phase reactants C-reactive protein and ferritin related to the disease course of patients with systemic lupus erythematosus.

Objective: To obtain insight in the acute-phase response in SLE.

Methods: The clinical history, SLEDAI, CRP and ferritin concentrations were analysed throughout the disease course of 10 SLE patients.

Results: During a mean follow-up of 4.

A prospective study on silicone breast implants and the silicone-related symptom complex.

This cohort study prospectively evaluated the prevalence of the silicone-related symptom complex (SRSC) in relation to antinuclear antibodies (ANA) and magnetic resonance imaging (MRI) of silicone breast implants (SBI) 1 year after implantation. A total of 57 women undergoing mastectomy followed by immediate breast reconstruction (IBR) and SBI between March 1995 and March 1997 at the University Hospital Rotterdam/Daniel den Hoed Cancer Centre, were prospectively evaluated. Just before and 1 year after IBR the sera of these women were tested for the presence of ANA and they were screened for the prevalence of SRSC-related symptoms by questionnaire.

[Clinical thinking and decision making in practice. A young woman with fever, arthralgia and exanthema].

A 19-year-old woman was admitted because of high fever, rash, arthralgia and sore throat. On physical examination a diffuse skin rash was observed, leaving a facial mask unaffected. C-reactive protein and erythrocyte sedimentation rate were raised (114 mg/l and 26 mm in the first hour, respectively); white blood cell count was normal (6.

Regulation of ferritin: a specific role for interferon-alpha (IFN-alpha)? The acute phase response in patients treated with IFN-alpha-2b.

Background: Adult onset of Still's disease is characterized by very high serum ferritin levels, in disproportion with other acute phase proteins (APPs). Because interferon-alpha (IFN-alpha) was observed to cause hyperferritinaemia in three healthy people without increase of other APPs, we hypothesized that IFN-alpha stimulates specifically the synthesis of ferritin. To test this hypothesis, we studied ferritin and other APP levels in patients treated with IFN-alpha.

Systemic lupus erythematosus. Disease outcome in patients with a disease duration of at least 10 years: second evaluation.

Data related to the disease course of patients with systemic lupus erythematosus (SLE) with special attention to the persistence of disease activity in the long term are scarce. At this moment reliable figures are only known about the survival rate as a measure of outcome. The aim of this multicenter study was to describe the outcome of SLE patients with a disease duration of greater than 10 y.

Incomplete lupus erythematosus: results of a multicentre study under the supervision of the EULAR Standing Committee on International Clinical Studies Including Therapeutic Trials (ESCISIT).

Objective: Patients characterized with antinuclear antibodies (ANA) and disease symptoms related to one organ system can be described as having incomplete systemic lupus erythematosus (SLE). The aim of this multicentre study was to describe the outcome of these so-called incomplete SLE patients. Two aspects of the outcome were studied: (i) the disease course, defined by the presence or absence of clinical symptoms; and (ii) the number of patients that eventually developed full SLE.

First evaluation study of the Dutch Working Party on silicone breast implants (SBI) and the silicone-related symptom complex (SRSC).

This cohort study evaluates the postoperative prevalence of antinuclear antibodies (ANA) in relation to symptoms related to the so-called silicone-related symptom complex (SRSC). A total of 63 women who underwent mastectomy followed by immediate breast reconstruction with a silicone implant (SBI) between Septembber 1990 and May 1995 at the University Hospital Rotterdam/Daniel den Hoed Cancer Center, participated voluntarily in the study. Their sera were tested for the presence of antinuclear antibodies (ANA) and at the same time they were screened for the prevalence of SRSC-related symptoms by questionnaire.

Systemic toxicity and cytokine/acute phase protein levels in patients after isolated limb perfusion with tumor necrosis factor-alpha complicated by high leakage.

Background: Since the introduction of high-dose tumor necrosis factor-alpha (TNFalpha) in the setting of isolated limb perfusion (ILP) in the clinic, prevention of leakage to the body of the patient is monitored with great precision for fear of TNF-mediated toxicity. That we observed remarkably little toxicity in patients with and without leakage prompted us to determine patterns of cytokines and acute phase proteins in patients with high leakage and in patients without any leakage.

Methods: TNFalpha, interleukin (IL)-6, IL-8, C-reactive protein, and secretory (s)-phospholipase A2 were measured at several time points during and after (until 7 days) ILP in 10 patients with a leakage to the systemic circulation varying in percentage from 12% to 65%.

[Diagnostic significance of antinuclear antibodies].

In three patients, women of 17, 25 and 15 years, suffering from arthralgia and in whom the existence of antinuclear antibodies (ANA) was established, the diagnosis 'systemic lupus erythematosus' was made or considered. Upon reevaluation, the ANA results could not be confirmed. The conclusion was drawn that in patients, who lack one or more clinical signs of a connective tissue disease (CTD), no indication is present for determination of ANA.

Intrapleural administration of tumour necrosis factor-alpha (TNFalpha) in patients with mesothelioma: cytokine patterns and acute-phase protein response.

Background: Tumour necrosis factor-alpha (TNFalpha) has been found to be very effective in the isolated limb perfusion setting for advanced extremity tumours. In a phase I study of intrapleural administration of TNFalpha 5 patients were followed for inflammatory response patterns.

Patients And Methods: Malignant mesothelioma patients were treated with repeated intrapleural administration of 0.

Histone-containing immune complexes are to a large extent responsible for anti-dsDNA reactivity in the Farr assay of active SLE patients.

Increased titres of anti-dsDNA antibodies, especially if of high avidity, are associated with renal exacerbations in patients with systemic lupus erythematosus (SLE). One of the most reliable assays to measure anti-dsDNA antibodies, the Farr assay, is believed to detect preferentially high avidity antibodies. Purified non-complexed monoclonal antibodies (mAbs) against nucleosomes, obtained from mice with SLE, are not reactive in the Farr assay, but can become so once complexed to nucleosomes.

Systemic lupus erythematosus: clinical features in patients with a disease duration of over 10 years, first evaluation.

Objective: Most information available about the disease course of patients with systemic lupus erythematosus (SLE) is restricted to the first 5 yr after disease onset. Data about the disease course 10 yr after disease onset are rare. The aim of this multicentre study was to describe the outcome of SLE patients with a disease duration of >10 yr.

Recombinant human erythropoietin improves health-related quality of life in patients with rheumatoid arthritis and anaemia of chronic disease; utility measures correlate strongly with disease activity measures.

Treatment with recombinant human erythropoietin (r-hu-Epo) in patients with rheumatoid arthritis (RA) and anaemia of chronic disease (ACD) resulted in improvement of both anaemia and disease activity. Utilities represent a generic and comprehensive quality of life measure, capable of integrating domain-specific information into one overall value which a patient assigns to his state of health. Therefore, the effect of r-hu-Epo on quality of life was studied by measuring utilities, derived from the rating scale and standard gamble, in a 52-week placebo-controlled randomised double-blind study with r-hu-Epo in 70 patients with active RA and ACD.
