DRUG THERAPY

Relative cardiovascular safety of celecoxib, naproxen, and ibuprofen (December 2016)

The cardiovascular (CV) safety of celecoxib, the COX-2 selective nonsteroidal anti-inflammatory drug (NSAID), compared with other NSAIDs, is a matter of debate. In a randomized trial (PRECISION) involving over 24,000 patients with arthritis and either known CV disease or CV risk factors, the CV safety of celecoxib was noninferior to both naproxen and ibuprofen, two nonselective NSAIDs [1]. Depending upon the analysis, about 2 to 5 percent of subjects experienced a CV event during follow-up, which was slightly lower than the expected event rate. Despite some limitations, this trial suggests that celecoxib in moderate doses can be administered, when indicated, without concern about increased CV risk compared with the nonselective nonsteroidal agents naproxen and ibuprofen. (See "COX-2 selective inhibitors: Adverse cardiovascular effects", section on 'Celecoxib' and "Nonselective NSAIDs: Adverse cardiovascular effects", section on 'Risk of myocardial infarction, stroke, and death'.)

Biosimilars for tumor necrosis factor inhibitors (August 2016)

Copies of biologic agents, termed biosimilars, including several of the tumor necrosis factor (TNF) inhibitors and other medications, have been marketed or are under development for use in the rheumatic diseases. A recent systematic review of 19 observational studies and clinical trials compared biosimilar TNF-alpha inhibitors with their reference biologic products, including infliximab, etanercept, and adalimumab, with testing done in healthy volunteers and in patients with rheumatoid arthritis, inflammatory bowel disease, and ankylosing spondylitis [2]. Pharmacokinetic measurements were within defined equivalence margins, and similar clinical responses and adverse events were found for the tested products and their reference drugs. Additionally, similar efficacy and safety were observed in four cohort studies in which patients were switched from the reference product to a biosimilar medication. Limitations for many of the studies included small sample size and short trial duration, but collectively these data illustrate the potential utility of these agents. (See "Overview of biologic agents and kinase inhibitors in the rheumatic diseases", section on 'Biosimilars for biologic agents'.)

ORTHOPEDICS, SPINE, AND SOFT TISSUE RHEUMATIC DISORDERS

Investigational autologous nasal chondrocyte grafts for articular cartilage defects (November 2016)

Replacing localized regions of degenerated cartilage with autologous chondrocytes grafts may be beneficial for selected patients with less severe, localized articular cartilage defects. There is an interest in using alternative sources of autologous chondrocytes with superior cartilage-forming capacity compared with articular chondrocytes. In a proof-of-concept, first-in-human trial, 10 patients with symptomatic, post-traumatic, full-thickness cartilage lesions on the femoral condyle or trochlea were treated with engineered tissue from autologous nasal cartilage [3]. Significant improvements in pain, knee function, and quality of life were found during the 24-month follow-up period. These early data will need further validation to establish efficacy and appropriateness of this approach for treating articular cartilage defects. (See "Overview of surgical therapy of knee and hip osteoarthritis", section on 'Autologous chondrocyte implantation'.)

Vertebroplasty for osteoporotic compression fractures (November 2016)

The indications for and timing of vertebroplasty for the treatment of osteoporotic compression fractures are controversial. In a trial comparing vertebroplasty or simulated vertebroplasty (sham) in 120 patients with acute (less than six weeks) vertebral fracture and back pain, more patients in the vertebroplasty group achieved clinically significant lower pain scores at 14 days [4]. Two previous sham-controlled trials, however, did not show a significant reduction in pain with vertebroplasty, likely due to differences in study design, including different sham procedures for the control arm and varying definitions of acute vertebral fracture. (See "Osteoporotic thoracolumbar vertebral compression fractures: Clinical manifestations and treatment", section on 'Vertebroplasty'.)

Treatment of degenerative meniscal tears (September 2016)

Acute meniscal tears often benefit from surgical treatment, but the appropriate management of chronic, degenerative tears, particularly in middle-aged adults, has been a source of debate. A recent trial randomly assigned 140 middle-aged adults (mean age 49.5) with a degenerative meniscal tear (and no evidence of osteoarthritis on magnetic resonance imaging [MRI]) to receive exercise therapy or partial meniscectomy [5]. The trial found no clinically significant difference in knee function or pain at two years of follow-up. This finding is consistent with several other small randomized trials that have reported no clinically significant benefit from arthroscopic surgery in such patients. In the absence of persistent joint effusions or mechanical dysfunction, we suggest physical therapy as the initial management for middle-aged patients with degenerative meniscal tears. (See "Meniscal injury of the knee", section on 'Chronic degenerative meniscal injury'.)

OSTEOARTHRITIS

Lack of benefit of chondroitin and glucosamine for knee osteoarthritis (January 2017)

The use of glucosamine and chondroitin for osteoarthritis (OA) has been controversial, with most studies showing little to no evidence of clinically meaningful benefit. In a multicenter randomized trial, 164 patients with moderate to severe knee osteoarthritis were treated with either placebo or chondroitin sulfate plus glucosamine [6]. At six months' follow-up, the mean reduction in the global pain score was greater in the placebo group, and there were no between-group differences in patient-reported function or other outcomes. Although the study was limited by the small size and potentially inadequate dosing of chondroitin and glucosamine, it is likely that the combination of glucosamine and chondroitin is no better than placebo in patients with knee osteoarthritis. (See "Initial pharmacologic therapy of osteoarthritis", section on 'Glucosamine and chondroitin'.)

OSTEOPOROSIS

Effect of antihypertensive drug class on fracture rates (January 2017)

Thiazide diuretics stimulate distal tubular reabsorption of calcium, leading to a decrease in urinary calcium excretion and a possible benefit on bone mineral density. The rates of hip or pelvic fractures among patients treated with thiazide-like diuretics, angiotensin converting enzyme (ACE) inhibitors, or calcium channel blockers were compared in a post-hoc analysis of the ALLHAT trial [7]. At approximately five years, those randomly assigned chlorthalidone had fewer hip or pelvic fractures as compared with those assigned to either lisinopril or amlodipine. Thus, if monotherapy is appropriate in a patient with hypertension and osteoporosis, thiazide-like diuretics may have advantages over ACE inhibitors, angiotensin receptor blockers (ARBs), and calcium channel blockers. (See "Choice of drug therapy in primary (essential) hypertension", section on 'Thiazide diuretics'.)

Investigational parathyroid hormone-related peptide analog for postmenopausal osteoporosis (October 2016)

Abaloparatide is an investigational synthetic analog of parathyroid hormone-related peptide (PTHrP) that binds more selectively than parathyroid hormone 1-34 (teriparatide) to the PTH1 receptor, conferring a more transient response favoring bone formation and minimizing bone resorption and hypercalcemia. In a phase III trial, nearly 2500 postmenopausal women with osteoporosis were randomly assigned to abaloparatide, placebo, or open-label teriparatide [8]. Compared with placebo, new radiographic vertebral fractures occurred less frequently in the abaloparatide and teriparatide groups. The incidence of hypercalcemia was lower with abaloparatide than teriparatide. (See "Overview of the management of osteoporosis in postmenopausal women", section on 'Emerging therapies'.)

Investigational monoclonal anti-sclerostin antibody for postmenopausal osteoporosis (September 2016)

Sclerostin is secreted by osteocytes and inhibits bone formation. Romosozumab, a monoclonal anti-sclerostin antibody under investigation for the treatment of osteoporosis, has been shown to improve bone density in postmenopausal women. In a trial specifically designed to assess radiographic vertebral fracture outcomes, 7180 postmenopausal women with osteoporosis were randomly assigned to romosozumab (210 mg subcutaneously once monthly) or placebo for 12 months [9]. Thereafter, all women received denosumab (60 mg subcutaneously every six months) for an additional 12 months. The incidence of radiographic vertebral fracture was lower in the romosozumab group at 12 months (0.5 versus 1.8 percent) and 24 months (0.6 versus 2.5 percent). There was an increased frequency of injection site reactions in the romosozumab group. Ongoing trials should provide more information about safety and efficacy, including nonvertebral fracture reduction. (See "Overview of the management of osteoporosis in postmenopausal women", section on 'Emerging therapies'.)

PEDIATRIC RHEUMATOLOGY

Adjuvant glucocorticoids for initial treatment of Kawasaki disease (January 2017)

The use of glucocorticoids to treat children with Kawasaki disease has been a subject of debate. In a meta-analysis of comparative studies examining initial treatment with glucocorticoids plus intravenous immune globulin (IVIG) compared with IVIG alone, combination therapy was associated with a lower rate of coronary artery abnormalities, with the greatest benefit in patients predicted to be at high risk for IVIG resistance at baseline [10]. The Kobayashi criteria can be used to determine this risk status in Japanese children but are not reliable in other populations. When increased risk for IVIG resistance cannot be determined, we do not recommend routine use of glucocorticoids for initial therapy. (See "Kawasaki disease: Initial treatment and prognosis", section on 'Glucocorticoids'.)

SCLERODERMA AND OTHER SYSTEMIC RHEUMATIC DISEASES

Management of microvascular damage in systemic sclerosis (December 2016)

Vasoactive drugs are used for systemic sclerosis (SSc) patients with severe Raynaud phenomenon (RP) and digital ulcers. For prevention of recurrent digital ulcers, there may be a benefit from combination therapy with intravenous iloprost and bosentan. In a prospective observational study with 30 SSc patients receiving intravenous iloprost for severe secondary RP, half of the patients were also given bosentan following the development of digital ulcers or pulmonary arterial hypertension [11]. After four years of follow-up, the iloprost plus bosentan group showed evidence of a significant improvement in digital microvasculature structure and function, which also corresponded with a significant reduction in the incidence of new digital ulcers. This limited study needs confirmation but suggests that combination therapy may be helpful in complex SSc patients with recurrent digital ulcers. (See "Treatment of the Raynaud phenomenon resistant to initial therapy", section on 'Recurrent digital ulcers in systemic sclerosis'.)

Mycophenolate mofetil for scleroderma lung disease (October 2016)

Cyclophosphamide has been the suggested treatment for moderate-to-severe interstitial lung disease complicating systemic sclerosis (SSc-ILD) but has well-known toxicity. A recent randomized trial compared mycophenolate mofetil (MMF) with oral cyclophosphamide in 142 patients with SSc-ILD, exertional dyspnea, and features of progressive disease [12]. Pulmonary function and dyspnea improved in both groups, without a significant difference between groups. MMF was better tolerated than cyclophosphamide based on a longer time to patient withdrawal and lower incidence of leukopenia and thrombocytopenia. We now suggest initiating treatment for symptomatic progressive SSc-ILD with mycophenolate, rather than cyclophosphamide, due to comparable efficacy, better safety profile, and the option for longer-term therapy. (See "Treatment and prognosis of interstitial lung disease in systemic sclerosis (scleroderma)", section on 'Choice of an agent'.)

Guidelines for the treatment of systemic sclerosis (October 2016)

The British Society for Rheumatology (BSR) and the British Health Professionals in Rheumatology (BHSR) have published a comprehensive set of guidelines for the management of systemic sclerosis (SSc) [13]. Some of the key points include the importance of making an early diagnosis and considering treatment with an immunosuppressive agent in patients with diffuse cutaneous SSc of less than three years' duration. They also review the major therapies for treating organ-based disease and emphasize the importance of referring patients to specialty centers with access to multidisciplinary care. (See "Overview of the treatment and prognosis of systemic sclerosis (scleroderma) in adults", section on 'General principles of management'.)

SYSTEMIC LUPUS ERYTHEMATOSUS AND SJOGREN'S SYNDROME

Accuracy of the spot urine protein to creatinine ratio in patients with kidney disease (October 2016)

A spot urine protein to creatinine ratio (UPCR) is frequently used to estimate 24-hour proteinuria and to follow the effects of treatment in patients with proteinuric kidney diseases. However, a longitudinal study of patients with biopsy-proven glomerular disease [14] and a systematic review of studies of patients with lupus nephritis [15] have demonstrated that a spot UPCR may not accurately predict the result of a 24-hour urine, particularly in patients with lower degrees (<1 g/day) of proteinuria. These findings support our recommendation that a 24-hour urine collection should be the method of choice for initial quantification of proteinuria and for verification of changes in proteinuria before therapy is altered in patients with kidney disease. (See "Assessment of urinary protein excretion and evaluation of isolated non-nephrotic proteinuria in adults", section on 'Accuracy of spot urine estimates'.)

Screening and prevention of hydroxychloroquine retinopathy (August 2016)

Antimalarial agents hydroxychloroquine (HCQ) and chloroquine are widely used for the treatment of systemic lupus erythematosus, rheumatoid arthritis, and other inflammatory and dermatologic conditions, and are generally thought to be safe. Retinal toxicity is a known risk, however, and measures to minimize this potential toxicity are necessary. Recently, the American Academy of Ophthalmology issued revised recommendations for screening and prevention of retinopathy [16]. Key changes include the following:

The maximum daily dose of HCQ should not exceed 5 mg/kg (previously 6.5 mg/kg), and the maximum daily dose of chloroquine should not exceed 2.3 mg/kg (previously 3 mg/kg).

Real body weight should be used to calculate dose limits instead of ideal body weight.

In addition to exceeding the recommended daily dose, major risk factors for retinal toxicity include antimalarial use for greater than five years, renal disease, concomitant tamoxifen use, and the presence of macular disease. All patients should undergo a baseline eye examination before or within a year of beginning treatment with an antimalarial drug and, if normal, at least annually after five years of exposure for patients without major risk factors. For the treatment of rheumatic diseases, we typically use standard daily doses of HCQ (non-weight-based, eg, up to 400 mg) in individuals weighing 80 kg or more. In patients weighing less than 80 kg, we use a lower daily dose of HCQ up to the maximum of 5 mg/kg of real body weight. (See "Antimalarial drugs in the treatment of rheumatic disease", section on 'Ocular health'.)

OTHER RHEUMATOLOGY

Anakinra for familial Mediterranean fever (January 2017)

Anti-interleukin (IL)-1 therapy has been the preferred second-line therapy for patients with familial Mediterranean fever (FMF) based on data from case reports and case series. In the first randomized trial to evaluate anti-IL-1 therapy in colchicine-resistant FMF, 24 patients from a single center received daily injections of either anakinra or placebo and were followed for four months [17]. Patients in the anakinra group had fewer attacks per month, significant improvement in quality of life, and no severe adverse events. Thus, anakinra appears to be a safe and effective alternative for patients who do not respond to or cannot tolerate colchicine. (See "Management of familial Mediterranean fever", section on 'Interleukin-1 inhibition'.)

Adalimumab for noninfectious uveitis (November 2016)

Patients with noninfectious uveitis can benefit from effective and safe glucocorticoid-sparing therapy. Two well-designed, randomized trials showed that adalimumab was effective in the treatment of noninfectious intermediate, posterior, and pan-uveitis [18,19]. In these trials, adalimumab improved the time-to-treatment failure in patients with uveitis who followed a tapering schedule for oral glucocorticoids. Both the European Medicines Agency and the US Food and Drug Administration recommended approval of adalimumab for adults with these forms of uveitis. (See "Uveitis: Treatment", section on 'Anti-tumor necrosis factor-alpha'.)

Rhabdomyolysis and sickle cell trait (August 2016)

Sickle cell trait is a benign carrier condition with a normal life expectancy. However, concerns have been raised regarding an increased risk of rhabdomyolysis and sudden death with prolonged physical activity. These risks were addressed in a cohort study of almost 50,000 black soldiers in the United States army for whom sickle cell trait status and other clinical information was available [20]. While the risk of rhabdomyolysis was increased (hazard ratio, 1.5), this magnitude of risk is similar to that conferred by obesity or smoking and less than that due to antipsychotic or statin medications. Mortality was not increased over that in black soldiers without sickle cell trait, and the sole death from rhabdomyolysis occurred in an individual without sickle cell trait. Interventions to reduce exertion-related injuries should be aimed at all athletes and members of the military, regardless of sickle cell trait status. (See "Sickle cell trait", section on 'Rhabdomyolysis and sudden death during strenuous physical activity'.)
