Magnetic resonance imaging in polymyalgia rheumatica-contrast enhancement is not always needed

BACKGROUND

Extracapsular inflammation at entheseal sites in the pelvic girdle as demonstrated by magnetic resonance imaging (MRI) was shown to be useful as an additional tool for diagnosing polymyalgia rheumatica (PMR). However, it is unclear whether MRI needs to be performed with contrast enhancement or whether oedema-sensitive sequences are sufficient.

OBJECTIVE

To evaluate the performance of T2w TIRM (turbo inversion recovery magnitude) imaging compared to fat-saturated contrast-enhanced (ce) T1w at predefined pelvic sites to detect extracapsular inflammation in patients with PMR.

METHODS

A total of 120 pelvic MRIs of patients with pelvic girdle pain, 40 with clinically diagnosed PMR and 80 controls, were retrospectively scored by three blinded radiologists separately evaluating the MRI with and without contrast enhancement at 19 previously defined pelvic structures. The intra- and interrater reliability and the diagnostic performance of both techniques were statistically analysed and evaluated.

RESULTS

The detection of inflammatory MRI signals correlated moderately between both techniques (Cohen's κ 0.583). With ceT1w imaging 20.7% more sites were detected as inflamed compared to T2w TIRM in PMR patients. Inter- and intrareader reliability was superior with ceT1w imaging. If the inflammatory signal was detected at three sites bilaterally including the origin of the rectus femoris muscle or adductor longus muscle, the sensitivity and specificity was 100% and 97.1% by ceT1w imaging vs. 80.8% and 93.3% by T2w TIRM, respectively.

CONCLUSION

Contrast enhancement is superior to oedema-sensitive MRI in the detection of extracapsular inflammation in PMR. However, using T2w TIRM also detects many but not all PMR cases.

[Polymyalgia rheumatica-A challenge in geriatrics : Interdisciplinary presentation of diagnostics and treatment]

Polymyalgia rheumatica is the second most frequent inflammatory rheumatic disease in people aged over 50 years, after rheumatoid arthritis. It is characterized by pain and morning stiffness in the region of the shoulders, hip girdle and neck. It can be associated with giant cell arteritis (CGA). Treatment with glucocorticoids is indispensable. The duration of treatment varies and often exceeds 1 year. The additive administration of methotrexate is an option for saving glucocorticoids. The biologicals tocilizumab or secukinumab are very promising alternatives. The course of treatment should be closely monitored for inflammation parameters, glucocorticoid side effects, pain, visual acuity, depression, activities of daily living and especially related to functions of the upper extremities. The geriatric assessment plays an important role in the management of this condition.

Polymyalgia Rheumatica

BACKGROUND

Polymyalgia rheumatica (PMR) is among the most common inflammatory rheumatic diseases in older adults. Presumed risk factors include female sex, previous infections, and genetic factors. No epidemiological data on PMR in Germany have been available until now.

METHODS

This review is based on publications retrieved by a selective literature search in PubMed. Moreover, the administrative incidence and prevalence of PMR in the years 2011-2019 was determined from data of the AOK Baden-Württemberg statutory health insurance carrier for insurees aged 40 and older. In addition, we quantified the number of consultations with physicians involved in the diagnosis.

RESULTS

The annual age- and sex-standardized incidence and prevalence of PMR from 2011 to 2019 were 18.6/100 000 persons and 138.8/100 000 persons, respectively. The incidence was higher in women than in men (21.8/100 000 vs. 12.8/100 000 persons per year). 60% of the cases were diagnosed in primary care practices. The treatment of PMR with orally administered glucocorticoids usually results in a treatment response within a few days to weeks. Approximately 43% of patients experience recurrent symptoms within a year, requiring adjustment of the glucocorticoid dose. For older patients with impaired physical ability, additional non-pharmacological treatment with exercise programs plays an important role.

CONCLUSION

PMR usually takes an uncomplicated course under treatment and can be managed in primary care, but these patients are often multimorbid and require frequent follow-up. Along with research on the etiology of the disease, further studies are needed to identify the risk factors for a chronic course and to evaluate the potential effects of non-pharmacological measures.

[Glucocorticoid-induced osteoporosis-Focus treatment (part 1)]

With a fracture prevalence of 30-50%, glucocorticoid (GC)-induced osteoporosis is one of the most important comorbidities in inflammatory rheumatic diseases. Because of a reduction of bone quality with a lack of correlation with bone mineral density, the fracture risk during long-term GC treatment is not sufficiently represented by the currently available methods of osteodensitometry and therefore underestimated. According to the Confederation for Osteology (DVO) guidelines, a baseline osteological diagnosis including osteodensitometry is indicated in all postmenopausal women and in men aged 60 years and older who receive or are scheduled to receive GC at a dose of ≥ 2.5 mg prednisolone equivalent/day for > 3 months. Basic measures in GC-treated patients include vitamin D and calcium supplementation as well as measures to promote muscle strength and coordination and to prevent falls. The indications for a specific osteological treatment depend on the calculated GC dose, age, sex, and other fracture risk factors in addition to bone mineral density and prevalent fractures.

[Chronic inflammatory demyelinating polyneuropathy as differential diagnosis to polymyalgia rheumatica]

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare disease affecting the peripheral nerves. The disease causes symmetric weakness of certain muscle groups, mainly affecting the hips and shoulders. In some patients a loss of sensitivity occurs. We report a case of symmetric and proximal weakness of the legs, which was found together with an elevation of inflammatory markers. The first tentative diagnosis was polymyalgia rheumatica; however, an interdisciplinary work-up of the case finally led to the diagnosis of CIDP in combination with infectious endocarditis.

Vessel Wall Inflammatory Activity as Determined by F-18 Fluorodeoxyglucose PET in Large Vessel Vasculitis Is Attenuated by Immunomodulatory Drugs

F-18 fluorodeoxyglucose (F-18 FDG) PET/CT plays an increasing role in the diagnostic workup of large vessel vasculitis (LVV); however, information on the relationship between immunosuppressive drugs and vessel wall uptake is limited. In 94 patients with a confirmed diagnosis of LVV, the vessel wall-to-liver ratio (VLR) was assessed in eight vessel segments. Patients were grouped according to intake of immunomodulatory drugs (Group 1, prednisone; Group 2, prednisone + methotrexate; and Group 3, prednisone + others) and compared to treatment-naïve individuals. A total of 54/94 (57.4%) were treated with immunomodulatory drugs (Group 1, 29/49 (53.7%); Group 2, 9/54 (16.7%); Group 3, 11/54 (20.4%); and Group 4, 5/54 (9.3%)), whereas the remainder received no therapy (40/94 (42.6%)). The mean VLR of the arterial segments correlated significantly with the hematopoietic organs (r ≥ 0.22, p ≤ 0.05), c-reactive protein (r ≥ 0.25, p ≤ 0.05), and prednisone dosage (r ≥ −0.4, p ≤ 0.05). Relative to treatment-naïve patients, a significantly lower VLR was recorded in 5/8 (62.5%) of the investigated vessel segments in Group 1 (p ≤ 0.02), in 6/8 of the vessel segments in Group 2 (75.0%, p ≤ 0.006), and in 7/8 of the segments in Group 3 (87.5%, p ≤ 0.05). In LVV, the F-18 FDG uptake in vessel wall as a marker of inflammatory activity was attenuated by immunomodulatory drugs, which provides a foundation for future serial monitoring of treatment efficacy.

[Polymyalgic complaint: is there a tumor behind it?]

HISTORY

A 61-year-old caucasian male presenting with pain in arms and thighs, weight loss of 10 kg in the last 3 months, and subfebrile temperatures, also had abdominal pain. In addition, he reported that his abdominal circumference had increased over the last two years.

FINDINGS AND DIAGNOSIS

Based on patient's complaints and the presence of elevated inflammatory markers in the absence of specific antibodies or peripheral synovitis a clinical diagnosis of polymyalgia rheumatica was made. The patient had an immediate clinical response to 20 mg prednisone/day, and inflammatory markers normalized. An abdominal MRI showed no signs of polymyalgia rheumatica but revealed a lipomatous mass with displacement of the adjacent intraabdominal and intrapelvine organs. Histologically a highly differentiated retroperitoneal liposarcoma was described.

THERAPY AND COURSE

The patient underwent a complete resection of the tumor. Because the liposarcoma was highly differentiated, the oncologists were reluctant to use any additional therapy.

CONCLUSIONS

The diagnostic work up of polymyalgic complaints should also include rare paraneoplastic diseases.

[Treatment of giant cell arteritis and polymyalgia rheumatica]

Patients with untreated active giant cell arteritis (GCA) are at high risk of permanent vision loss. Therefore, treatment with glucocorticoids should be immediately initiated at an initial dose of 40-60 mg prednisolone equivalent dose per day. Once remission is achieved, the prednisolone dose should be reduced to 15-20 mg within 2-3 months and then to ≤5 mg per day within 1 year. Glucocorticoid-sparing treatment with tocilizumab or alternatively methotrexate should be initiated in patients with an increased risk or pre-existing complications of glucocorticoid treatment and patients with relapse. In polymyalgia rheumatica, prednisolone dosages of 15-25 mg/day are sufficient. After achieving remission, the dose should then be reduced to 10 mg within 4-8 weeks and then to 1 mg per month thereafter. Glucocorticoid-sparing treatment with methotrexate should be initiated in patients with an increased risk or existing complications of glucocorticoid treatment, relapse or increased glucocorticoid requirements.

[Oral glucocorticoids : Therapeutic use and treatment monitoring in inflammatory rheumatic diseases]

Glucocorticoids (GC) have been proven drug substances in rheumatology for more than 70 years. They act very rapidly in high doses through membrane stabilizing effects. Genomic therapeutic effects of GC even in very low doses are mainly due to inhibition of the functions of the transcription factor nuclear factor kappa B (NFkB), which promotes the synthesis of proinflammatory mediators, adhesion molecules and other regulatory proteins. Indications for the use of GC in high doses in rheumatology are always given when a life-threatening, dangerous or treatment-resistant situation is involved. Lower doses of GC, usually administered orally, are particularly used in rheumatoid arthritis, vasculitis and collagenosis. In clinical practice the general principle is to use the smallest possible effective dose of GC for the shortest possible time in order to achieve the therapeutic effect of GC without running the risk of unacceptably severe side effects.

[Polymyalgia rheumatica and Giant Cell Arteritis - Update on Diagnosis and Therapy]

Polymyalgia rheumatica and Giant Cell Arteritis - Update on Diagnosis and Therapy Abstract. Polymyalgia rheumatica (PMR) is an inflammatory syndrome which often co-incides with giant cell arteritis (GCA). Due to unspecific symptoms and a plethora of possible alternative diagnoses, PMR often represents a diagnostic challenge. The use of ultrasound, but also other imaging methods has improved and accelerated the time to diagnosis in PMR and GCA, so that complications such as blindness can be reduced. Glucocorticoids are still the main initial therapy for both diseases. Although further research is needed concerning prevention of and screening for long term complications for GCA, the efficacy of biologicals, namely tocilizumab, has markedly increased therapeutic options for GCA and allows for a reduction of side effects.

[Rheumatological care in the Rheumazentrum Ruhrgebiet Rheumatism Center-a model for conurbations]

The Ruhrgebiet Rheumatism Center, which is highly specialized for rheumatic diseases, is the largest of its kind in Germany. For many years it has fulfilled all the requirements for structural quality required by the Association of Rheumatological Acute Clinics (VRA) including regular participation in the KOBRA benchmarking project. Therefore, the center regularly receives the VRA seal for quality of care. In 2018 more than 7500 patients were treated as inpatients. Within the framework of care according to §116b (ASV since May 2019) there were nearly 25,000 outpatient patient contacts. Furthermore, an early screening program (triage) was established 5 years ago in order to be able to identify patients with musculoskeletal complaints on a potentially inflammatory rheumatic basis. This functions in the sense of an early diagnosis and treatment in accordance with the treat-to-target concept within less than 4 weeks (initially) on an outpatient basis with respect to the required urgency, in order to subsequently provide sound diagnostic support. In the last 2 years 2017 and 2018, this deadline was met in more than 90% of cases. Within the scope of inpatient care approximately one third of patients were treated in recent years with a defined rheumatological complex therapy and 10% with pain complex therapy. Approximately 3% were treated with geriatric complex therapy and 65% were short-stay patients (<4 days), i.e. patients who received the necessary diagnostics and treatment on an inpatient basis at short notice. The overall structure of the rheumatism center, the cooperation with rheumatologists in private practice, many cooperation partners, referring physicians and patients represents a model for rheumatological care in large conurbations. The care of large numbers of patients also enables the further training of many assistants and this is essential for the future of good rheumatological medicine.

[Promotion of physical activity for older patients with rheumatism : Characteristics of inflammatory rheumatic diseases against the background of physical activity recommendations]

Due to the wide range of positive effects and the clear evidence of effectiveness, physical activity is one of the most important treatments for inflammatory rheumatic diseases. Because of the frequent overlap of disease and age-related aspects in older patients, the implementation of the German national physical activity recommendations has to be checked and accompanied by physicians. To get the older patients in motion, a patient-centered approach is required that takes the individual health problem(s) and the current context of life into account. This article provides an overview of the activity-related characteristics of older patients with inflammatory rheumatic diseases. Against this background a simple strategy is provided for promoting physical activity during medical consultation, which takes the characteristics of older patients with rheumatism into consideration. In this way, physicians can integrate a targeted, resource and time-saving economic strategy into consultations that is in concordance with the national physical activity recommendations.
