Patient Subgroup Response to Belimumab Remains Unclear

DESTIN, FLA. – For now, the lupus patients most likely to respond to recently approved belimumab may be those with moderate to severe disease without renal or central nervous system involvement who have failed to respond to standard therapy, according to Dr. R. John Looney.

More specific details on which patients are most likely to benefit will require further experience with the drug, he said at the Congress of Clinical Rheumatology.

Belimumab (Benlysta), which was approved in March, is the first new drug for systemic lupus erythematosus (SLE) in 50 years. It has a very good safety profile, although the effect size, while statistically significant, is relatively small, with only an average of about a 12 percentage point difference in the response rates between treatment and placebo in trials of the fully human monoclonal antibody that inhibits B-lymphocyte stimulator, said Dr. Looney, professor of medicine at the University of Rochester (N.Y.).

Still, that reflects improvement of about 25%-30%, he noted.

The standard dosage is 10 mg/kg, given intravenously every 2 weeks for three times, then every 4 weeks, in addition to standard care.

Keep in mind that the onset is somewhat slow, so this "may not be a drug you would use in a flaring patient," Dr. Looney said.

Also, it has not been studied in severe renal or central nervous system disease, nor in combination with cyclophosphamide, he noted.

Furthermore, no particular subgroup has yet been identified in whom the drug has particular benefits, so it is a bit of a challenge to determine who should be put on this drug.

"I would consider it in patients with moderate to severe, nonrenal, nonneurologic disease who have failed standard therapy," Dr. Looney said, explaining that he would consider those to be patients with continued disease activity or patients in whom steroids can’t be tapered or stopped despite treatment.

"So I look at this as a drug that might help me get my patients who are on hydroxychloroquine and let’s say CellCept [mycophenolate] or Imuran [azathioprine], down to a manageable dose of steroids," he added.

Determining how long to treat, however, is a challenge.

"We have no good way to look at an individual patient and say they are better and they are better because they are on belimumab," Dr. Looney said, noting that based on belimumab trial data, three out of four patients who were responders at 1 year would have been responders on placebo, so further study is needed to help guide treatment duration.

"I would also really like to see predictors of response," he said, noting that such predictors have thus far not been reported.

Further analysis of existing data may be useful for identifying subgroups who will respond best to belimumab. Additional studies in renal and CNS disease would also be useful.

"It may be that you add this drug to current therapies [in renal and CNS patients] and they do that much better," Dr. Looney said, noting that it would also be useful to look at belimumab treatment in conjunction with cyclophosphamide and rituximab as well "to see what happens when B cells are targeted in two different ways."

Dr. Looney disclosed that he has been an adviser for Genentech.

Consider Celiac Disease in Autoimmune Disorder Patients

Consider Celiac Disease in Autoimmune Disorder Patients

DESTIN, FLA. – Consider screening for celiac disease in children with juvenile idiopathic arthritis, arthromyalgias, and myositis, advised Dr. Alexa B. Adams at the Congress of Clinical Rheumatology.

Celiac disease has a strong association with numerous autoimmune disorders. Untreated celiac disease poses serious health consequences, such as short stature, failure to thrive, osteopenia/osteoporosis, and enteropathy-associated T-cell lymphoma. Early diagnosis and treatment could obviate or reduce the need for the more aggressive treatments that are typically prescribed for these associated autoimmune disorders, said Dr. Adams, a pediatric rheumatologist and pediatrician at Cornell University, New York.

The identification and treatment of celiac disease in the setting of autoimmune disorders also appear to have the potential to alter the course of subsequent autoimmune disease, she said.

A link between celiac disease and juvenile idiopathic arthritis (JIA), for example, is well established. Several studies have demonstrated an increased prevalence of celiac disease among children with JIA, and cases of celiac disease in association with juvenile spondyloarthropathies and with pauciarticular, polyarticular, and psoriatic arthritis also have been reported. Furthermore, data show that a gluten-free diet can improve the musculoskeletal symptoms that are associated with celiac disease.

The mechanisms for the association between JIA and celiac disease are unknown, but may be related to ongoing intestinal permeability in untreated celiac disease, Dr. Adams said, adding that she advocates screening for celiac disease in all JIA patients.

She described a case involving a 6-year-old boy who presented with pain and swelling of the knee as well as morning stiffness. He had previously been treated for Lyme disease, and he had a 2-year history of headaches, behavioral problems, and poor growth, compared with his identical twin.

Based on physical and laboratory examinations (serology was negative for celiac disease) and after the young patient was referred to pediatric infectious disease and neurology specialties where he underwent lumbar puncture and brain MRI, the treatment focused on possible central nervous system Lyme disease. Although his joint complaints were resolved, he had persistent headaches, poor growth, and worsening transaminitis.

The boy tested negative for infectious and autoimmune hepatitis. An abdominal ultrasound showed fatty infiltration of the liver. Ultimately, the child was referred to a pediatric gastroenterologist. Work-up, including duodenal biopsy, showed findings that were consistent with celiac disease, and a gluten-free diet was initiated.

"On a gluten-free diet, the child’s headaches resolved, he had no recurrence of joint pain, he was growing and gaining weight, and he had no further behavioral issues," Dr. Adams said.

An early diagnosis of celiac disease in a JIA patient and early initiation of a gluten-free diet can prevent unnecessary treatment with NSAIDs, disease-modifying antirheumatic drugs, and anti–tumor necrosis factor agents. The patent can also avoid unnecessary imaging and joint injections.

Associations between celiac disease and adult rheumatoid arthritis/seronegative arthritides also exist, but are not as robust as that seen between celiac disease and JIA.

The coexistence of adult RA and positive celiac antibodies – including EmA (endomysial antibodies) and gliadin IgA – has been well described, but an association with biopsy-proven celiac disease has not borne out, Dr. Adams said.

The same is true in adult spondyloarthropathy.

It is possible that there are age-related differences in gluten tolerance or in the pathogenesis of arthritis and/or gut permeability that can explain the age-related differences, but this remains unclear, she noted.

As for celiac disease and myositis, the associations are well documented in both the pediatric rheumatology and pediatric gastroenterology literature, and also (although only more recently) in the adult literature.

Interestingly, a high prevalence of the DQAI*0501 allele is found in both diseases, Dr. Adams noted.

Because treatment of inflammatory myositis often requires significant use of glucocorticoids and sometimes additional immunosuppressive therapy, screening for celiac disease should be considered in myositis patients, she said, describing two cases involving young girls who were diagnosed with myositis and polymyositis, respectively. Both failed to respond adequately to prednisone/methotrexate, and both are doing well now on only a gluten-free diet after being diagnosed with celiac disease on biopsy.

Screen for celiac disease in patients with vague musculoskeletal complaints who don’t respond to treatment, she said. These are the patients with whom "you just don’t know what to do," she said, adding that these are the patients who don’t clearly have arthritis, whose symptoms are out of proportion to findings on examination, whose symptoms impact their participation in sports or other activities, and who fail to respond well to a number of treatments. Often these patients will be diagnosed with fibromyalgia – a diagnosis that is unusual in young patients and should raise concern about possible other causes, she added.

 

 

In these cases, maintain a high index of suspicion for celiac disease, she said, describing the case of a 16-year-old girl who had given up sports because of a 2-year history of increasing pain in the calves, forearms, Achilles tendon, heels, and back. The skin on her thighs and calves was sensitive to touch, but she had no GI symptoms and had normal growth.

Massage, chiropractic manipulation, acupuncture, electrical stimulation, and saline injection in her calf all failed to alleviate her symptoms. The child was diagnosed with fibromyalgia and treated with gabapentin, an over-the-counter NSAID, as well as intensive physical therapy.

After a gastroenterology referral, she was diagnosed with celiac disease based on biopsy findings, and was started on a gluten-free diet. At 5 months, she was symptom free and was once again active in sports activities.

Given the consistent findings associating celiac disease with certain autoimmune disorders, and the safety and effectiveness of the gluten-free diet that is used to treat celiac disease, screening deserves consideration in these patients, she concluded.

An association between celiac disease and systemic autoimmune disease has been reported, but is less established than the association between celiac disease and nonsystemic autoimmune disorders, Dr. Adams said.

Reports of a link between celiac disease and systemic lupus erythematosus (SLE), for example, are limited to case reports, and at this point should be "taken with a grain of salt," she said.

However, it does appear that in children the celiac disease diagnosis typically precedes the SLE diagnosis, whereas the converse is true in adults.

Also, reports of SLE following celiac disease despite histologic normalization of the celiac disease on biopsy suggest that the treatment of celiac disease via a gluten-free diet does not modify the disease course in SLE, as it appears to do in cases of arthritis and myositis (J. Clin. Gastroenterol. 2008;42:252-5), Dr. Adams said.

There does, however, appear to be a fairly strong association between celiac disease and Sjögren’s syndrome.

A 2003 report said Sjögren’s syndrome is present in up to 15% of patients with biopsy-proven celiac disease, and demonstrated that anti-tTG (tissue transglutaminase, a marker for celiac disease) is more prevalent in Sjögren’s syndrome than in other systemic rheumatic diseases (J. Rheumatol. 2003;30:2613-9).

Systemic sclerosis and morphia have also been reported in association with celiac disease, Dr. Adams said.

The strongest associations between celiac disease and systemic autoimmune disease are with adult idiopathic diabetes mellitus, autoimmune thyroid disease, Addison’s disease, and polyendocrinopathies, she added.

More data are needed to define the prevalence of celiac disease in various subtypes of systemic autoimmune disease, she concluded.

Dr. Adams serves as a speaker for Abbott Pharmaceuticals. She had no other relevant disclosures.

Reports of a link between celiac disease and systemic lupus erythematosus (SLE), for example, are limited to case reports, and at this point should be "taken with a grain of salt," she said.

However, it does appear that in children the celiac disease diagnosis typically precedes the SLE diagnosis, whereas the converse is true in adults.

Also, reports of SLE following celiac disease despite histologic normalization of the celiac disease on biopsy suggest that the treatment of celiac disease via a gluten-free diet does not modify the disease course in SLE, as it appears to do in cases of arthritis and myositis (J. Clin. Gastroenterol. 2008;42:252-5), Dr. Adams said.

There does, however, appear to be a fairly strong association between celiac disease and Sjögren’s syndrome.

A 2003 report said Sjögren’s syndrome is present in up to 15% of patients with biopsy-proven celiac disease, and demonstrated that anti-tTG (tissue transglutaminase, a marker for celiac disease) is more prevalent in Sjögren’s syndrome than in other systemic rheumatic diseases (J. Rheumatol. 2003;30:2613-9).

Systemic sclerosis and morphia have also been reported in association with celiac disease, Dr. Adams said.

The strongest associations between celiac disease and systemic autoimmune disease are with adult idiopathic diabetes mellitus, autoimmune thyroid disease, Addison’s disease, and polyendocrinopathies, she added.

More data are needed to define the prevalence of celiac disease in various subtypes of systemic autoimmune disease, she concluded.

DESTIN, FLA. – Consider screening for celiac disease in children with juvenile idiopathic arthritis, arthromyalgias, and myositis, advised Dr. Alexa B. Adams at the Congress of Clinical Rheumatology.

Celiac disease has a strong association with numerous autoimmune disorders. Untreated celiac disease poses serious health consequences, such as short stature, failure to thrive, osteopenia/osteoporosis, and enteropathy-associated T-cell lymphoma. Early diagnosis and treatment could obviate or reduce the need for the more aggressive treatments that are typically prescribed for these associated autoimmune disorders, said Dr. Adams, a pediatric rheumatologist and pediatrician at Cornell University, New York.

The identification and treatment of celiac disease in the setting of autoimmune disorders also appear to have the potential to alter the course of subsequent autoimmune disease, she said.

A link between celiac disease and juvenile idiopathic arthritis (JIA), for example, is well established. Several studies have demonstrated an increased prevalence of celiac disease among children with JIA, and cases of celiac disease in association with juvenile spondyloarthropathies and with pauciarticular, polyarticular, and psoriatic arthritis also have been reported. Furthermore, data show that a gluten-free diet can improve the musculoskeletal symptoms that are associated with celiac disease.

The mechanisms for the association between JIA and celiac disease are unknown, but may be related to ongoing intestinal permeability in untreated celiac disease, Dr. Adams said, adding that she advocates screening for celiac disease in all JIA patients.

She described a case involving a 6-year-old boy who presented with pain and swelling of the knee as well as morning stiffness. He had previously been treated for Lyme disease, and he had a 2-year history of headaches, behavioral problems, and poor growth, compared with his identical twin.

Based on physical and laboratory examinations (serology was negative for celiac disease) and after the young patient was referred to pediatric infectious disease and neurology specialties where he underwent lumbar puncture and brain MRI, the treatment focused on possible central nervous system Lyme disease. Although his joint complaints were resolved, he had persistent headaches, poor growth, and worsening transaminitis.

The boy tested negative for infectious and autoimmune hepatitis. An abdominal ultrasound showed fatty infiltration of the liver. Ultimately, the child was referred to a pediatric gastroenterologist. Work-up, including duodenal biopsy, showed findings that were consistent with celiac disease, and a gluten-free diet was initiated.

"On a gluten-free diet, the child’s headaches resolved, he had no recurrence of joint pain, he was growing and gaining weight, and he had no further behavioral issues," Dr. Adams said.

An early diagnosis of celiac disease in a JIA patient and early initiation of a gluten-free diet can prevent unnecessary treatment with NSAIDs, disease-modifying antirheumatic drugs, and anti–tumor necrosis factor agents. The patent can also avoid unnecessary imaging and joint injections.

Associations between celiac disease and adult rheumatoid arthritis/seronegative arthritides also exist, but are not as robust as that seen between celiac disease and JIA.

The coexistence of adult RA and positive celiac antibodies – including EmA (endomysial antibodies) and gliadin IgA – has been well described, but an association with biopsy-proven celiac disease has not borne out, Dr. Adams said.

The same is true in adult spondyloarthropathy.

It is possible that there are age-related differences in gluten tolerance or in the pathogenesis of arthritis and/or gut permeability that can explain the age-related differences, but this remains unclear, she noted.

As for celiac disease and myositis, the associations are well documented in both the pediatric rheumatology and pediatric gastroenterology literature, and also (although only more recently) in the adult literature.

Interestingly, a high prevalence of the DQAI*0501 allele is found in both diseases, Dr. Adams noted.

Because treatment of inflammatory myositis often requires significant use of glucocorticoids and sometimes additional immunosuppressive therapy, screening for celiac disease should be considered in myositis patients, she said, describing two cases involving young girls who were diagnosed with myositis and polymyositis, respectively. Both failed to respond adequately to prednisone/methotrexate, and both are doing well now on only a gluten-free diet after being diagnosed with celiac disease on biopsy.

Screen for celiac disease in patients with vague musculoskeletal complaints who don’t respond to treatment, she said. These are the patients with whom "you just don’t know what to do," she said, adding that these are the patients who don’t clearly have arthritis, whose symptoms are out of proportion to findings on examination, whose symptoms impact their participation in sports or other activities, and who fail to respond well to a number of treatments. Often these patients will be diagnosed with fibromyalgia – a diagnosis that is unusual in young patients and should raise concern about possible other causes, she added.

 

 

In these cases, maintain a high index of suspicion for celiac disease, she said, describing the case of a 16-year-old girl who had given up sports because of a 2-year history of increasing pain in the calves, forearms, Achilles tendon, heels, and back. The skin on her thighs and calves was sensitive to touch, but she had no GI symptoms and had normal growth.

Massage, chiropractic manipulation, acupuncture, electrical stimulation, and saline injection in her calf all failed to alleviate her symptoms. The child was diagnosed with fibromyalgia and treated with gabapentin, an over-the-counter NSAID, as well as intensive physical therapy.

After a gastroenterology referral, she was diagnosed with celiac disease based on biopsy findings, and was started on a gluten-free diet. At 5 months, she was symptom free and was once again active in sports activities.

Given the consistent findings associating celiac disease with certain autoimmune disorders, and the safety and effectiveness of the gluten-free diet that is used to treat celiac disease, screening deserves consideration in these patients, she concluded.

She described a case involving a 6-year-old boy who presented with pain and swelling of the knee as well as morning stiffness. He had previously been treated for Lyme disease, and he had a 2-year history of headaches, behavioral problems, and poor growth, compared with his identical twin.

Based on physical and laboratory examinations (serology was negative for celiac disease) and after the young patient was referred to pediatric infectious disease and neurology specialties where he underwent lumbar puncture and brain MRI, the treatment focused on possible central nervous system Lyme disease. Although his joint complaints were resolved, he had persistent headaches, poor growth, and worsening transaminitis.

The boy tested negative for infectious and autoimmune hepatitis. An abdominal ultrasound showed fatty infiltration of the liver. Ultimately, the child was referred to a pediatric gastroenterologist. Work-up, including duodenal biopsy, showed findings that were consistent with celiac disease, and a gluten-free diet was initiated.

"On a gluten-free diet, the child’s headaches resolved, he had no recurrence of joint pain, he was growing and gaining weight, and he had no further behavioral issues," Dr. Adams said.

An early diagnosis of celiac disease in a JIA patient and early initiation of a gluten-free diet can prevent unnecessary treatment with NSAIDs, disease-modifying antirheumatic drugs, and anti–tumor necrosis factor agents. The patent can also avoid unnecessary imaging and joint injections.

Associations between celiac disease and adult rheumatoid arthritis/seronegative arthritides also exist, but are not as robust as that seen between celiac disease and JIA.

The coexistence of adult RA and positive celiac antibodies – including EmA (endomysial antibodies) and gliadin IgA – has been well described, but an association with biopsy-proven celiac disease has not borne out, Dr. Adams said.

The same is true in adult spondyloarthropathy.

It is possible that there are age-related differences in gluten tolerance or in the pathogenesis of arthritis and/or gut permeability that can explain the age-related differences, but this remains unclear, she noted.

As for celiac disease and myositis, the associations are well documented in both the pediatric rheumatology and pediatric gastroenterology literature, and also (although only more recently) in the adult literature.

Interestingly, a high prevalence of the DQAI*0501 allele is found in both diseases, Dr. Adams noted.

Because treatment of inflammatory myositis often requires significant use of glucocorticoids and sometimes additional immunosuppressive therapy, screening for celiac disease should be considered in myositis patients, she said, describing two cases involving young girls who were diagnosed with myositis and polymyositis, respectively. Both failed to respond adequately to prednisone/methotrexate, and both are doing well now on only a gluten-free diet after being diagnosed with celiac disease on biopsy.

Screen for celiac disease in patients with vague musculoskeletal complaints who don’t respond to treatment, she said. These are the patients with whom "you just don’t know what to do," she said, adding that these are the patients who don’t clearly have arthritis, whose symptoms are out of proportion to findings on examination, whose symptoms impact their participation in sports or other activities, and who fail to respond well to a number of treatments. Often these patients will be diagnosed with fibromyalgia – a diagnosis that is unusual in young patients and should raise concern about possible other causes, she added.

 

 

In these cases, maintain a high index of suspicion for celiac disease, she said, describing the case of a 16-year-old girl who had given up sports because of a 2-year history of increasing pain in the calves, forearms, Achilles tendon, heels, and back. The skin on her thighs and calves was sensitive to touch, but she had no GI symptoms and had normal growth.

Massage, chiropractic manipulation, acupuncture, electrical stimulation, and saline injection in her calf all failed to alleviate her symptoms. The child was diagnosed with fibromyalgia and treated with gabapentin, an over-the-counter NSAID, as well as intensive physical therapy.

After a gastroenterology referral, she was diagnosed with celiac disease based on biopsy findings, and was started on a gluten-free diet. At 5 months, she was symptom free and was once again active in sports activities.

Given the consistent findings associating celiac disease with certain autoimmune disorders, and the safety and effectiveness of the gluten-free diet that is used to treat celiac disease, screening deserves consideration in these patients, she concluded.

An association between celiac disease and systemic autoimmune disease has been reported, but is less established than the association between celiac disease and nonsystemic autoimmune disorders, Dr. Adams said.

Reports of a link between celiac disease and systemic lupus erythematosus (SLE), for example, are limited to case reports, and at this point should be "taken with a grain of salt," she said.

However, it does appear that in children the celiac disease diagnosis typically precedes the SLE diagnosis, whereas the converse is true in adults.

Also, reports of SLE following celiac disease despite histologic normalization of the celiac disease on biopsy suggest that the treatment of celiac disease via a gluten-free diet does not modify the disease course in SLE, as it appears to do in cases of arthritis and myositis (J. Clin. Gastroenterol. 2008;42:252-5), Dr. Adams said.

There does, however, appear to be a fairly strong association between celiac disease and Sjögren’s syndrome.

A 2003 report said Sjögren’s syndrome is present in up to 15% of patients with biopsy-proven celiac disease, and demonstrated that anti-tTG (tissue transglutaminase, a marker for celiac disease) is more prevalent in Sjögren’s syndrome than in other systemic rheumatic diseases (J. Rheumatol. 2003;30:2613-9).

Systemic sclerosis and morphia have also been reported in association with celiac disease, Dr. Adams said.

The strongest associations between celiac disease and systemic autoimmune disease are with adult idiopathic diabetes mellitus, autoimmune thyroid disease, Addison’s disease, and polyendocrinopathies, she added.

More data are needed to define the prevalence of celiac disease in various subtypes of systemic autoimmune disease, she concluded.

DESTIN, FLA. – Consider screening for celiac disease in children with juvenile idiopathic arthritis, arthromyalgias, and myositis, advised Dr. Alexa B. Adams at the Congress of Clinical Rheumatology.

Celiac disease has a strong association with numerous autoimmune disorders. Untreated celiac disease poses serious health consequences, such as short stature, failure to thrive, osteopenia/osteoporosis, and enteropathy-associated T-cell lymphoma. Early diagnosis and treatment could obviate or reduce the need for the more aggressive treatments that are typically prescribed for these associated autoimmune disorders, said Dr. Adams, a pediatric rheumatologist and pediatrician at Cornell University, New York.

The identification and treatment of celiac disease in the setting of autoimmune disorders also appear to have the potential to alter the course of subsequent autoimmune disease, she said.

A link between celiac disease and juvenile idiopathic arthritis (JIA), for example, is well established. Several studies have demonstrated an increased prevalence of celiac disease among children with JIA, and cases of celiac disease in association with juvenile spondyloarthropathies and with pauciarticular, polyarticular, and psoriatic arthritis also have been reported. Furthermore, data show that a gluten-free diet can improve the musculoskeletal symptoms that are associated with celiac disease.

The mechanisms for the association between JIA and celiac disease are unknown, but may be related to ongoing intestinal permeability in untreated celiac disease, Dr. Adams said, adding that she advocates screening for celiac disease in all JIA patients.
