Outcomes

Primary Outcome Measures

Change in Dermatomyositis-associated Calcinosis of a Single Lesion by Assessing Its Severity as Measured by a Difference in Physician Calcinosis Visual Analog Scales.
Change in dermatomyositis-associated calcinosis of a single lesion by assessing its severity as measured by a difference in Physician Calcinosis Visual Analog Scales. The Visual Analog Scale range is from zero (0) to ten (10). Zero (0) being no evidence of disease activity and ten (10) being extremely active or severe disease activity. A negative percent change indicates improvement in the lesion.

Secondary Outcome Measures

Change in Dermatomyositis-associated Calcinosis of a Single Lesion by Assessing Its Hardness as Measured by a Difference in Durometer (Rex Durometer Model 1600, Type OO) Measurements.
Change in dermatomyositis-associated calcinosis of a single lesion by assessing its hardness as measured by a difference in durometer (Rex durometer Model 1600, Type OO) measurements. The range of a durometer is from 0 to 100. The higher the durometer reading, the harder the lesion. Improvement in the lesion hardness would result in a negative change over time.
Change in Dermatomyositis-associated Calcinosis of a Single Lesion by Assessing Its Severity as Measured by a Difference in Patient Calcinosis Visual Analog Scales.
Change in dermatomyositis-associated calcinosis of a single lesion by assessing its severity as measured by a difference in Patient Calcinosis Visual Analog Scales. The scale ranges from zero (0) to ten (10). Zero (0) being no evidence of disease activity and ten (10) being extremely active or severe disease activity. A negative change would indicate improvement in the disease activity. A positive change would indicate worsening of disease activity.
Change in Size of Dermatomyositis-associated Calcinosis Area on Lesions as Measured by a Difference in Plain Film (X-ray) Studies.
Change in dermatomyositis-associated calcinosis as measured by a difference in centimeters in plain film (x-ray) studies. X rays were compared between baseline and final assessment for any changes.
Change in Patient Functionality and/or Quality of Life.
This will be assessed through the use of the Dermatology Life Quality Index (DLQI), Health Assessment Questionnaire (HAQ)/Childhood Health Assessment Questionnaire (CHAQ), Manual Muscle Testing (MMT8), and range of motion evaluations. DLQI index scores range from 0 to 30. The higher the score, the more quality of life is impaired.Change in scores from baseline to final assessment yielding a negative percent change indicate an improvement in DLQI. HAQ scales range from 0 to 3. The higher the score, the greater the disability. Change in scores from baseline to final assessment yielding a negative percent change indicate an improvement in the HAQ. MMT8 testing results in a score between 0 and 150. The higher the score, the more normal the function of the muscle. A positive percent change would indicate an improvement in MMT8 testing results.

5. Study Description

Brief Summary
Dermatomyositis is an inflammatory muscle disorder that is often associated with many skin findings. One of the skin findings seen in up to 50% of individuals with juvenile dermatomyositis, an early onset form of this condition, and up to 20-30% of adult dermatomyositis patients who have not responded to treatment, is calcinosis, or deposits of calcium within the skin and muscle tissue. In addition to being cosmetically unappealing, involvement of deeper tissues with calcinosis may lead to contractures, or shortening of muscles, which may have a significant impact on functioning and quality of life. Unfortunately, there is no known effective treatment of dermatomyositis associated calcinosis. However, recent reports have shown that a medication called sodium thiosulfate has been effective in treating individuals with calciphylaxis, a condition where calcium is deposited within blood vessels, and with tumoral calcinosis, a genetic form of calcification, when receiving this medication by vein. In addition, recent advances in laser technology have led to the development of methods that may allow topical medications to penetrate deeper layers of the skin. The investigators have designed a pilot study to evaluate the use of topical sodium thiosulfate solution in treating superficial calcinosis in individuals with juvenile and adult dermatomyositis. The investigators will use laser to assist in the delivery of this medication to areas of calcinosis.
Detailed Description
Five individuals who meet the eligibility criteria will take part in this study. They will have a variety of assessments performed throughout the treatment period in order to evaluate both dermatomyositis and calcinosis severity and their potential response to fractional carbon dioxide and sodium thiosulfate treatment. A medical history will be taken and baseline assessments will be performed during the screening period. Serum creatinine kinase levels will be determined on this visit and repeated at the end of the study (week 20); these levels will be one measure of monitoring disease activity during the study. One calcinosis lesion will be treated, assessed, and followed. If a second calcinosis lesion is present, it will act as a control (not treated). Two weeks prior to the first treatment session, an optional (not required) skin biopsy of the target (treated) calcinosis lesion will be offered to the the first 3 patients ≥ 18 years of age to determine optimal fractional carbon dioxide laser settings that will be used for treatment. Area and durometer (a device that measures hardness) measurements and photographs of the calcinosis lesions will be performed at weeks 0,4,8,12,16,and 20. One x-ray of the control and one x-ray of the target calcinosis lesion will also be performed during the screening period and at week 20. Assessment of muscle strength, physical functioning, endurance, and range of motion, as well as myositis activity outside of the muscles will be performed during the screening period and at weeks 8 and 20. Myositis damage assessment will be performed at the screening period and at week 20. Questionnaires to assess physical functioning pertaining to activities of daily living and quality of life, as well as the quality of life related to skin disease and the calcinosis lesions will be completed during the screening period and at weeks 8 and 20. Treatment of the target calcinosis lesion with fractional carbon dioxide laser and topical sodium thiosulfate will occur on weeks 0,2,4,6,8,10,12,14,16,and 18. Each patient will receive a total of 8-10 treatments over a 6 month period. Assessments for any side effects from the treatment will be performed prior to each treatment session on weeks 0,2,4,6,8,10,12,14,16,18, and 20.
