Abstract | Acute pallid disc edema is frequently seen with giant cell arteritis (GCA) in elderly patients. Elevated acute phase reactants (e.g., erythrocyte sedimentation rate [ESR] or C-reactive protein [CRP]) can support diagnosis of GCA but is typically confirmed with a temporal artery biopsy (TAB) and treated with high-dose corticosteroid therapy to preserve vision. Calciphylaxis (CPA), or calcific uremic arteriolopathy, can mimic GCA, especially in the setting of chronic kidney disease (CKD). |

Bindiganavile, MD, Patricia ChevezBarrios, MD, Andrew G. Lee, MD A cute pallid disc edema is frequently seen with giant cell arteritis (GCA) in elderly patients. Elevated acute phase reactants (e.g., erythrocyte sedimentation rate [ESR] or C-reactive protein [CRP]) can support diagnosis of GCA but is typically confirmed with a temporal artery biopsy (TAB) and treated with high-dose corticosteroid therapy to preserve vision. Calciphylaxis (CPA), or calcific uremic arteriolopathy, can mimic GCA, especially in the setting of chronic kidney disease (CKD). The true diagnosis can be elucidated with TAB. Clinicians should be aware that CPA can produce pallid optic disc edema mimicking GCA. This article reports a patient who had calciphylaxis presenting with signs and symptoms similar to GCA and a review of other similar cases in the literature. CASE REPORT A 72-year-old African American man with a medical history of end-stage renal disease (ESRD) on hemodialysis, peripheral arterial disease, hypertension, and hyperlipidemia presented with acute painless loss of vision in his left eye. He had previous optic atrophy that was long-standing in his right eye from presumed previous ischemic optic neuropathy. He was admitted for management of dry gangrene of his left middle finger and on review of symptoms, denied headache, jaw claudication, weight loss, temple pain, or scalp tenderness. On eye examination, his visual acuity was 20/200 in the right eye and hand motions in the left eye. Pupils measured 2 mm bilaterally (both eyes) with a poor light reaction in both eyes but no relative afferent pupillary defect (RAPD). Anterior segment, motility, and intraocular pressure were within normal limits. Dilated fundus examination revealed a pale, atrophic nerve in the right eye and pallid disc edema in the left eye. ESR and CRP were both elevated at 104 mm/h and 6.78 mg/L, respectively. Testing for sarcoidosis, tuberculosis, Lyme disease, syphilis, aquaporin-4 antibodies, and myelin oligodendrocyte glycoprotein was negative. Contrast-enhanced MRI of the head and orbit showed no lesion. The vision loss and the pallid disc edema in the setting of elevated acute phase reactants raised suspicion for GCA, and intravenous (IV) methylprednisolone 1 gm was started. A dry gangrenous-appearing lesion was noted on his left middle finger, and a necrotic ulcer with a black eschar was noted on his right knee (Fig. 1). An X-ray study of the left hand revealed dense vascular calcifications and a suspected large partially calcified aneurysm adjacent to the radius. Parathyroid hormone (PTH) was elevated at 883 pg/mL (normal ,55), and serum calcium was normal at 9.3 mg/dL.

Clinical Correspondence Although the gangrenous lesion and CKD were previously known in this patient, neuro-ophthalmology was not consulted until the visual loss occurred. A TAB was performed, which revealed extensive calcification of all the layers of the artery but predominantly in the muscularis, compatible with a diagnosis of calciphylaxis (1) (Fig. 2). IV methylprednisolone was subsequently discontinued after 2 days of therapy. DISCUSSION CPA is a rare but increasingly recognized condition that can mimic GCA. There are 10 other reported cases of acute optic neuropathy due to calciphylaxis (Table 1) (2–10). Common ophthalmic manifestations include acute visual loss, a RAPD, and pallid optic disc edema. Some patients may have symptoms that are usually associated with GCA including jaw claudication and temporal headache. Four patients had concurrent soft tissue manifestations of calciphylaxis (2,4,5,9) with another 2 developed them within a year of vision change (6,8). Soft tissue involvement was confirmed directly with biopsy or seen on imaging. Common patient characteristics included 7 patients with CKD (2–6,8,10). Of the 3 patients without CKD, 1 was on hemodialysis for uremia and volume overload with laboratory findings of improper phosphorus balance (3), 1 was on chronic steroids for her rheumatoid arthritis (9), and 1 patient’s medical history was unknown (7). Multiple patients were on warfarin (3,4,6,9). TAB results revealed diffuse calcification of the temporal artery media and sometimes lamina, with no signs of inflammation confirming the diagnosis of CPA. ESR was commonly elevated as was either parathyroid hormone or phosphorus. Eight patients were on a course of steroids (7 on high dose (2,3,5–8)) for presumed GCA but were discontinued when no improvement in vision was seen or when biopsy indicated CPA (10). Sodium thiosulfate was given to 2 patients, as well as our patient, but again, no improvement was observed (9,10). Three of the 7 patients, whose clinic outcomes are known, died within a year of visual presentation (3,6,8). Given our patient’s age and comorbidities, acute, pallid edema normally is suggestive of GCA and must be ruled out given the severe complications. However, other causes of pallid disc edema, especially in the setting of ESRD, include uremia, ischemic optic neuropathy, and hyperparathyroidism. Acute phase reactants are often obtained but can confound diagnosis. In our patient, the increased ESR could have been due to his CKD, and the skin gangrene can produce elevated CRP levels (11). Thus, CPA should be considered in the differential diagnosis of any patient with the combination of these risk factors. Interestingly, the kidneys are not typically involved in GCA although it is considered to be a systemic inflammation (12); therefore, renal disease should be considered independent rather than a sequela of GCA.

Risk factors for CPA include CKD, defective calcium– phosphorus balance, other autoimmune disease, diabetes, alcoholic hepatitis, female sex, Caucasian ethnicity, and older age (13). CPA has also been implicated after medication use including warfarin, calcium supplements, and vitamin D (1,13). Corticosteroids, the mainstay of treatment for GCA, are an additional risk factor for CPA and were noted to be present in 61% of nonuremic patients who went on to develop CPA, in a 36-case systemic review (1). Although corticosteroid therapy before TAB is the standard approach for patients suspected of having GCA, steroids can worsen symptoms in CPA. Fortunately, our patient suffered no untoward effects of the short course of empiric steroids before the TAB result. Although CPA affects only around 1%–4% of patients with ESRD, in the presence of other manifestations of the disease, such as cutaneous lesions supported by arterial calcification on biopsy or imaging, CPA needs to be high on a provider’s index Duong et al: J Neuro-Ophthalmol 2022; 42: e362-e366 of clinical suspicion. CPA has a 1-year mortality of 45%–80%, and patients with ulcerated lesions have a higher risk due to superimposed infections and ensuing sepsis (1). Unfortunately, there is no known cure for CPA. Sodium thiosulfate is an antioxidant and a calcium chelator that has been used in the management of CPA. Retrospective studies showed some modest benefit; however, more studies are required (1,13). In the 2 patients who received sodium thiosulfate, 1 experienced improvement of their cutaneous lesions but neither saw any visual benefit (9,10). Owing to its high morbidity, there is a clear cognitive bias toward GCA when examining older patients with acute vision loss and pallid disc edema. GCA requires prompt treatment, which otherwise can lead to devastating consequences. However, in the setting of chronic renal disease, arterial calcifications with cutaneous manifestations (e.g., gangrene), and abnormalities in PTH or calcium levels, CPA should be e365 Copyright © North American Neuro-Ophthalmology Society.

Physicians should consider these potential cognitive biases and explore broader differentials, especially if therapy of one diagnosis (e.g., GCA) can be harmful to another diagnosis (e.g., calciphylaxis). Clinicians should be aware that CPA can mimic GCA. Both can cause headache, visual loss, pallid edema, and elevated acute phase reactants. However, corticosteroids are not useful in CPA and may worsen the disease. A TAB may be useful to confirm the diagnosis and exclude GCA. STATEMENT OF AUTHORSHIP Category 1: a.
