A sixty nine-year-old woman was admitted to the hospital because of further examination of hypercalcemia. On July 1990, she complained of general fatigue and loss of appetite. She was pointed out to have hypercalcemia (15.1mg/dl), urolithiasis, and renal insufficiency. CT films of the chest showed swelling of the mediastinal lymphnodes and CT of the abdomen nephrocalcinosis. Ga-scintigraphy demonstrated an abnormal accumulation of gallium in the mediastinum. Levels of the parathyroid hormone was normal. Levels of the serum calcium (13.7mg/dl), angiotensin converting enzyme (30.4IU/L) and 1.25 (OH)2D (87PG/ml) were elevated. Giant cells were found in the biopsy specimen of the lung. A significant relationship between the serum calcium and creatinine were observed (r = 0.76, p < 0.02). Proximal fractional reabsorption of sodium showed to be suppressed (47.7%), and distal fractional reabsorption of sodium showed to be normal (88.4%). From these findings hypercalcemia and urolithiasis was suggested to result from sarcoidosis. The hypercalcemia and renal insufficiency improved with corticosteroid therapy.

A middle aged man presented as a recalcitrant case of borderline leprosy with concomitant pulmonary tuberculosis and urolithiasis which continued to progress relentlessly despite adequate multiduring antileprosy and antitubercular treatment. After detailed and relevant workup, the diagnosis of sarcoidosis was made. Rapid clinical improvement occurred with steroid therapy.

Of 123 patients with sarcoidosis observed from 1971 to 1986, 4 had histologically proven renal involvement. Hypercalcemia was present in all of these 4 patients, hypercreatinemia in 3 and urolithiasis in one. Histologically renal interstitial nephritis or fibrosis was found in all 4 cases, and 3 cases showed sarcoid-like renale granulomas. In addition, nephrocalcinosis or mesangioproliferative glomerulonephritis was present in one patient each. Corticosteroid therapy corrected hypercalcemia in 3 patients and improved renal function in the patient with glomerulonephritis and in the case with interstitial fibrosis. One patient died of granulomatous myocarditis, renal insufficiency having been unaffected by corticosteroids.

Hypercalcaemia is one of the extra-pulmonary symptoms of sarcoidosis. We describe a case of acute and chronic renal failure due to urolithiasis and nephrocalcinosis probably caused by sunlight-induced hypercalcaemia in a patient with undiagnosed sarcoidosis. Attention must be given to excessive sun exposure and vitamin D intake in patients with sarcoidosis.

A 38-year-old woman was hospitalized in January 1994 with renal dysfunction and hypercalcemia. Before admission, she was diagnosed as having urolithiasis, and had been treated twice with extracorporeal shock wave lithotripsy (ESWL). Ophthalmologically, she exhibited iritis and secondary glaucoma. Hypercalcemia, an extremely low titer of parathyroid hormone (PTH), and elevation of angiotensin-converting enzyme (ACE) and lysozyme activity were noted. These findings suggested sarcoidosis, although the chest X-ray showed only fibrotic changes. Hypercalcemia was suspected of having been caused secondarily by sarcoidosis. Since her laboratory data also showed renal dysfunction and abnormal urinalysis, a renal biopsy was performed. The histological findings indicated a tubular and interstitial disorder without glomerular abnormality; calcium deposition, which was detected by X-ray energy dispersive analysis, was observed in the tubular cytoplasm. Administration of prednisolone alleviated the renal dysfunction and decreased the elevation of ACE activity and lysozyme level of the blood. Sarcoidosis is sometimes associated with hypercalcemia, but rarely with renal dysfunction. These findings suggested that sarcoidosis may be associated with renal dysfunction due to tubular injury caused by calcium deposition in the tubules, and that glucocorticoid therapy was effective for these disorders.

A 65-year-old man was admitted to our hospital because of thirstyness and left lower abdominal pain. On admission, he was found to have urolithiasis, renal insufficiency (BUN: 73 mg/dl, Crt: 4.4 mg/dl), and hypercalcemia (13.2 mg/dl). Chest X-ray films and computed tomograms showed enlargement and calcification of the hilar lymph nodes, and thickened interlobar fissures in both lungs. Levels of angiotensin converting enzyme (30.2 IU/l) and 1.25 (OH)2VitD3 (66.4 pg/ml) were elevated. Histologic examination of the specimen obtained from transbronchial lung biopsy showed non-caseous epithelioid cell granulomas. Because the level of parathyroid hormone was normal and no malignancies were detected, a diagnosis of sarcoidosis was made. Treatment with extracorporeal shock wave lithotripsy, transurethral lithotomy, saline infusion, and prednisolone (30 mg/day) alleviated the urolithiasis, renal insufficiency, and hypercalcemia. After discharge, the patient was followed up and given prednisolone therapy. About 1 month after the prednisolone dose had been tapered to 15 mg/day, the patient experienced dyspnea and facial and pedal edema. Because congestive heart failure was diagnosed, he was re-admitted to our hospital for a second time. Although he was then placed on intensive therapy, he died of ventricular tachycardia associated with sarcoidosis of the heart.

A 30-year-old black woman presented with a 1-year history of repeated episodes of worsening weight loss and fatigue. Physical examination showed no skin lesions and a chest roentgenogram was normal. Workup showed no obvious cause of recurrent renal stones. Finally, the detection of lymphadenopathy led to the diagnosis of extrapulmonary sarcoidosis. Up to 4% of all cases of sarcoidosis may present with urolithiasis only. Renal stones may be more common in severe cases of sarcoidosis, which affect blacks most frequently. Although not generally recommended for diagnostic purposes in sarcoidosis, in this case determination of the angiotensin-converting enzyme level was helpful in making the correct diagnosis. It is important that physicians are aware of the possibility that sarcoidosis may present as urolithiasis, even in the presence of a negative chest roentgenogram.

We report three cases of urolithiasis associated with sarcoidosis and reviewed the Japanese published reports. All cases had hypercalcemia, hyperuricemia, hypercalciuria and renal dysfunction. A serum level of 1,25-(OH)2D3 was elevated and intact parathyroid hormone (PTH) was decreased. Stone components were predominantly calcium oxalate. Abnormal calcium metabolism is a well-known feature of sarcoidosis and the reported prevalence of urolithiasis in patients with sarcoidosis was 1.3-14.0% in the English published reports. However, urolithiasis associated with sarcoidosis is uncommon in Japan and we could find only 16 documented cases including ours. Abnormal calcium metabolism is caused by an increase in serum concentration of 1,25-(OH)2D3, which is derived from endogenous overproduction in the pulmonary macrophages. If patients with urolithiasis have abnormal calcium metabolism, renal impairment and suppression of PTH, the possibility of sarcoidosis should be considered for a differential diagnosis. Also, it should be emphasized that the presence or developing of urolithiasis is to be monitored during follow up of patients with sarcoidosis.
