    Abstract:
    We reported a 29-year-old woman with autoimmune polyglandular deficiency (APGD) type 1 accompanied by progressive myopathy. She had chronic mucocutaneous candidiasis at the age of 3, primary hypothyroidism at 12, insulin dependent diabetes mellitus at 27, and adrenal insufficiency at 29 years. Laboratory findings indicated an underlying defect in cell mediated immunity. Meanwhile, she had progressive muscular weakness and wasting at the age of 22 years which brought her to our hospital at 29 years. On admission, she could not walk without support and raise her arms up to the level of shoulders. Moderate to severe muscle wasting as well as weakness was observed in the limb girdle muscles. Serum CK levels were mildly elevated. A needle EMG examination disclosed short-duration and low-amplitude polyphasic motor units at voluntary contraction with few fibrillations and positive sharp waves at rest. On muscle CT examination, decreased density was detected in the neck extensor, paravertebral, rectus femoris, vastus intermedius, biceps femoris and soleus muscles. Muscle biopsy was performed on the biceps brachii and rectus femoris muscles. The former showed chronic dystrophic changes including marked variation in fiber size with necrotic and degenerating process, interstitial fibrosis, and lobulated and right fibers. In the latter, in addition to variation in fiber size with some necrotic fibers and occasional multi-core structures, nemaline bodies were seen in approximately 30% of muscle fibers. The progressive muscle involvement in our patient might be induced from 1) endocrine abnormality, 2) autoimmune disorder, and/or 3) coincidental complication of nemaline myopathy or limb girdle muscular dystrophy. The clinical and laboratory examinations, however, failed to support any of them.(ABSTRACT TRUNCATED AT 250 WORDS)
