Subtotal parathyroidectomy was performed on 34 patients with severe renal insufficiency. The indications were grave clinical symptoms (pruritus, bone pains and mental disturbances), gastric ulcer and radiological abnormalities (metastatic calcifications, osteoporosis, fractures and subperiostal resorption). The serum calcium level was elevated in eight cases. The serum parathormone value was determined in 13 cases, it was elevated in all cases. Less than 500 mg tissue was removed in 12, between 500 and 6000 mg in 19 and over 6000 mg in 3 cases. Nodular hyperplasia was demonstrated in 11 and diffuse hyperplasia in 23 patients. The serum calcium and parathormone levels fell markedly after the operation, and pruritus, bone pains and mental disturbances were markedly alleviated. Complete recovery was achieved only by a successful renal transplantation, but the operation had often a favourable effect on the grave symptoms.

During the period 1971-1976, subtotal parathyroidectomy was performed on 34 patients with chronic renal failure, representing 8% of all uraemic patients treated on the Renal Ward. Preoperative treatment of renal failure was conservative therapy in 6, haemodialysis in 20 and renal transplantation in 8 patients. The operation was indicated by grave clinical symptoms (pruritus, bone pains and mental disturbances), gastric ulcer and radiological abnormalities (osteoporosis, fractures, subperiosteal resorption and metastatic calcifications). The serum immunoreactive parathyroid hormone was determined in 13 cases, and the value was elevated in all. The serum calcium level was elevated in 8 out of 34 cases. Less than 500 mg of parathyroid tissue was removed in 12 cases, between 500 and 6000 mg in 19 and over 6000 mg in 3. Nodular hyperplasia was present in 11 patients, diffuse hyperplasia in 23. Postoperatively marked falls in serum parathyroid hormone and serum calcium values were observed. The bone pains, pruritus and mental disturbances were alleviated, and the general condition was favourably influenced. The operation had a lesser and more retarded effect on the radiological changes. Complete recovery was only achieved with successful renal transplant. Parathyroidectomy often had a favourable effect on the grave symptoms and may, therefore, be considered in some cases of severe hyperparathyroidism secondary to chronic renal failure.

Autonomous hyperparathyroidism occurred in 15% of 152 patients maintained by long-term home dialysis during the past nine years. Twenty-two patients with elevated serum parathormone levels and progressive bone disease in the presence of normal serum phosphate and calcium levels were treated by subtotal parathyroidectomy. All had parathyroid hyperplasia. Eighteen of the 22 patients are presently alive and undergo dialysis. Symptoms of bone pain, pruritus, and muscle cramps had improved in three fourths of the patients. The serum parathormone level decreased from a preoperative average of 576 muLEq/mL to an average of 188 muLEq/mL postoperatively. All 18 patients, observed for six to 77 months, showed improvement in x-ray films of their bone disease. The autonomous hyperparathyroidism of end-stage renal disease is corrected by subtotal parathyroidectomy, and the effect is sustained.

Between 1969 and April 1975 24 patients with severe secondary hyperparathyroidism (sHPT) clinically presenting with uremic osteopathy required either total (n=5) or subtotal (n=18) parathyroidectomies, 17 patients were already supported by maintenance hemodialysis, 6 patients suffered from terminal renal insufficiency. The leading clinical symptoms consisted of general osteoporosis, spontaneous fractures, extraosseous calcifications and histologically proven dissecting fibroosteoclasia. After operation 18 patients experienced complete relief from their complaints and repair of their skeletal lesions, 2 patients required reexploration for an undetected hyperfunctioning 4th parathyroid gland, regretfully with no success. In 4 patients with subtotal parathyoidectomy a recurrence of varying intensity with increased PTH-secretion from the remnant had to be registered after months and years.-The indication for surgical treatment of sHPT due to chronic renal failure has to be based on two sets of findings: 1) inadequate longterm suppression of increased PTH secretion by conservative measures like high dialysate calcium concentration or oral calcium intake, serum phosphorus depletion by oral intake of aluminium hydroxyde and possibly also by Vit. D; 2) persistent hypercalcemia, progressive osteodystrophy and severe complaints like bone pain and pruritus.

Osteodystrophy is almost universally present in chronic renal failure. Mild, but detectable, abnormalities--especially in parathyroid hormone (PTH) secretion--occur even when the glomerular filtration rate is greater than 30 cc/min. Osteomalacia is common in areas in which vitamin D intake and exposure to sunlight are minimal; when these factors are plentiful, osteitis fibrosa predominates. Osteoporosis is seen with increasing frequency in hemodialyzed patients. Nonosseous complications of secondary hyper-parathyroidism include hypercalcemia, metastatic calcification and pruritus. The most important factor in the medical therapy of osteodystrophy is control of serum phosphate levels. Next, a positive calcium balance must be provided either by giving vitamin D as dihyrdotachysterol, raising dialysate calcium or administering calcium orally. Parathyroidectomy is sometimes indicated, especially when the patients are transplant candidates and manifest hypercalcemia. Whether or not transplant is contemplated, patients with persistently high calcium-phosphate products, severe metastatic calcification or rapidly progressive osteodystrophy should be considered for parathyroidectomy. Newer, experimental vitamin D preparations, such as 1,25-dihydroxycholecalciferol or 1-alpha-hydroxycholecalciferol, should improve the managemet of patients with renal osteodystrophy and decrease the need for parathyroidectomies.

Patients with uremia frequently have generalized pruritus that is usually related to a disturbance of calcium and phosphorus metabolism. This report describes three patients with uremia who had prurigo nodularis due to localized scratching and rubbing. The diagnosis of uremia in one case was made when the patient was hospitalized for evaluation of skin lesions.

Diets with a high-fiber content have been shown to produce some beneficial effects on metabolic factors in subjects with NIDDM. However, some controversies still exist. In this report, the long-term effect of guar gum (Guarina) on both glycemic and blood lipid profiles was assessed in a randomized, double-blind and cross-over study on 16 (seven male and nine female) subjects with NIDDM. Each subject received placebo (P) and Guarina (G) treatment for two eight-week periods separated by a four-week period to facilitate wash-out. Fasting plasma glucose levels showed significant improvement during G treatment but not during P treatment (151.7 +/- 7.9 vs 168.6 +/- 12.2 mg/dl, p less than 0.01 by paired Student's t test). Hemoglobin Alc levels decreased significantly during G treatment but not during P treatment (6.9 +/- 0.2 vs 7.2 +/- 0.8%, p less than 0.001). Fasting insulin concentrations also showed significant lowering during G treatment but not during P treatment (18.3 +/- 2.1 vs 23.1 +/- 2.9 U/ml, p less than 0.005). Other variables, including serum total cholesterol, triglyceride, HDLc, LDLc, sodium, potassium, chloride, magnesium and calcium levels showed no significant changes during G or P treatment. Ten out of the 16 patients (62.5%) suffered from side effects; these included abdominal cramps (one case), diarrhea (seven cases) and skin itching (one case). In conclusion, guar gum effectively lowers fasting plasma glucose and HbAlc levels in subjects with NIDDM. Hyperinsulinemia could also be ameliorated. The effectiveness and side effects of guar gum treatment should be cautiously evaluated in each NIDDM subject.

A 62-year-old woman presented with uveitis and abnormal chest X-ray (bilateral hilar adenopathy). Skin biopsy in 1983 had revealed non-caseating epithelioid cell granuloma consistent with sarcoidosis. Her serum biochemical investigations and exploratory laparoscopy suggested nodular liver cirrhosis, but biopsy was not performed. Both blood urea nitrogen (BUN) and serum creatinine values were within normal limits. She received prednisolone therapy of 15 mg daily initially, and later a maintenance dose of 5 mg daily. In 1985, she complained of skin itching and her laboratory data revealed severe renal insufficiency (BUN 97 mg/dl, serum creatinine 12.2 mg/dl) and hypercalcemia (corrected serum calcium level: 11.5 mg/dl). Prednisolone treatment (40 mg daily) resulted in a dramatic improvement of renal function as well as other clinical abnormalities due to sarcoidosis, without any significant changes in liver function. She died of cerebral infarction in 1989. Autopsy showed interstitial nephritis with tubular calcinosis and hyalinized glomeruli. It is postulated that hypercalcemia due to sarcoidosis contributed to the renal failure in this patient. This case suggests that renal damage due to sarcoidosis may be reversible with appropriate corticosteroid therapy.

The immunologic mechanisms responsible for the development of primary biliary cirrhosis (PBC) remain poorly defined, although recent investigations have provided new clues as to the role of cellular membrane proteins such as the mitochondrial autoantigens and intercellular adhesion molecules. Additionally, new therapeutic agents have become available that markedly enhance the prospect for medical management of both hepatic and extrahepatic manifestations of PBC. Definitive therapy with ursodeoxycholic acid and/or methotrexate, and symptomatic relief of pruritus with rifampicin or metronidazole may become standard in the years ahead. The results of their use to date in the treatment of PBC are detailed in this review. Successful therapy of hepatic osteodystrophy associated with PBC has yet to be achieved, although early data suggest a role for ursodeoxycholic acid, estrogen, calcium, and vitamin D in the management of this debilitating problem. Orthotopic liver transplantation continues to be successful for the management of advanced disease (greater than 70% 5-year survival) and will remain an essential therapeutic tool until definitive medical therapy for PBC becomes available.

The calcium antagonist, diltiazem is effective in the treatment of patients with various types of angina pectoris, as well as with essential and renovascular arterial hypertension. Sustained-release diltiazem in dose of 180 mg once daily is effective as sustained-release diltiazem in dose of 90 mg twice daily. Besides, in patients with stable angina pectoris and essential arterial hypertension the monotherapy with sustained-release diltiazem in dose of 180 mg is similarly effective as beta blockers and thiazide diuretics. However, monotherapy with sustained-release diltiazem is at least effective as monotherapy with sustained-release verapamil. Comparative clinical investigations showed that diltiazem is more effective than propranolol in decreasing ischemic attacks, whereas the risk of bradycardia is smaller. On the other hand, nifedipine (dihydropyridine calcium antagonist) is more effective than diltiazem in lowering ischemic electrocardiographic changes, incidence of attacks and improving working capability. The efficacy of diltiazem, nifedipine and verapamil is similar in the treatment of patients with spastic angina pectoris, whereas the least effective is propranolol. As far as the arterial hypertension is concerned, clinical investigations showed that the efficacy of diltiazem and nifedipine is similar. Side effects are relatively rare (1.8-9.6% patients) and depend on the dose (nausea, fatigue, dizziness, headache and itching).
