We report on clinical experiences obtained in 7 uremic patients treated since January 1976 3 times weekly by chronic hemofiltration. The observations which we collected in more than 300 treatments suggest that hemofiltration might be superior to conventional hemodialysis. The main advantages of this treatment are characterized by its better control of hypertension, hyperhydration, and possibly of uremic bone disease. Furthermore, the applied acrylonitrile membrane allows the removal of substances with a molecular weight up to 60,000, similar to the glomerular basement membrane. Additionally, we report on methodological problems, on the compatibility of hemofiltration, and finally on its efficiency for removal of different uremic solutes.

A young woman presented with a novel multisystem disease: painful periostitis, osteosclerosis, hypertension, and renal dysfunction. The similarity of some of this clinical picture to fluoride intoxication led to the discovery of massively elevated fluoride levels in serum, urine, and bone. Although initially an enigma, the source of fluoride was later found to be the illicit use of an anesthetic agent, methoxyflurane. This agents is one of a class of organofluorides that, by virtue of biotransformation, is a known cause of inorganic fluoride exposure. Though the drug is potentially nephrotoxic as generally used, exposure to it is transient and has not previously led to discernible bone disease.

The management of patients with chronic renal failure is complicated and demanding for both physician and patient, but is frequently rewarding. When specific treatment of the underlying cause is not possible, therapy is aimed at making the maximum use of existing nephrons and preventing further loss of nephrons through hypertension and infection. Careful attention to salt and water balance is necessary, and all patients and all drugs prescribed must be considered with care. Special problems exist with regard to anaemia, bone disease, pericarditis and hyperkalaemia. An important aspect of care at this time is the education of patients about the next major phase of management, dialysis and transplantation.

Primary hyperparathyroidism during pregnancy has been reported in 36 women; 1 new case is reported here. Screening by determining serum calcium levels is a valuable method of diagnosing the disease. Radioimmunoassay of serum parathyroid hormone (PTH) greatly aids in the diagnosis. Amniotic fluid PTH values are discussed. Hyperparathyroidism has a high association with progressive renal insufficiency, renal calculi, hypertension, and bone disease. During pregnancy, there is an increased incidence of stillborns, premature labor, and neonatal tetany. Acute hyperparathyroid crisis may result in maternal death. This is the first reported case surgically treated during the third trimester of pregnancy. Surgery should be considered when the diagnosis is made late in pregnancy, as this may protect the infant from neonatal tetany.

During the past decade, the morbidity and mortality associated with cardiac transplantation have decreased dramatically. The current survival for patients who undergo orthotopic cardiac transplantation is 80 to 90% at 1 year and 70 to 80% at 5 years; these results are attributed chiefly to improved immunosuppression and the consequent decrease in infectious illnesses and rejection. Because surgical mortality and technique have not changed appreciably during the past 20 years, improved survival can be ascribed to advances in the medical management of recipients of cardiac transplants. Medical problems frequently encountered in such patients include allograft rejection, allograft vasculopathy, hypertension, renal dysfunction, hyperlipidemia, hyperglycemia, malignant disorders, general surgical disease, and osteopenic bone disease. Hence, the expertise needed for management of patients who undergo cardiac transplantation is not confined to a particular specialty--optimal care necessitates the integrated efforts of a team, including transplant physicians and personnel to provide broad subspecialty and laboratory support. Meticulous management with proactive intervention and minimal effective immunosuppression will prevent or ameliorate many problems and contribute to increased survivorship and improved quality of life. For additional substantive improvement in long-term survival and quality of life for recipients of cardiac allografts, multicenter, prospective, and placebo-controlled clinical investigations will be necessary.

Over the last 25 years, the perceived clinical spectrum of primary hyperparathyroidism (HPT) has changed dramatically from a disorder characterized by severe bone and renal disease to one typically manifested by few or mild symptoms and little evidence of organ damage. Reasons for this change in spectrum include changing demographics (primary HPT is primarily a disease of the middle-aged and elderly), diffusion of medical knowledge leading to a higher index of suspicion, and improved clinical laboratory technology (especially inexpensive and accurate determination of serum calcium and parathyroid hormone). In the first 343 cases of primary HPT seen at the Massachusetts General Hospital, 57% had renal stones, 23% had hyperparathyroid bone disease, and less than 1% had no symptoms. By contrast, studies dating from the availability of automated serum calcium measurement found renal stones and hyperparathyroid bone disease in less than 5% of cases, and about half of cases had few or no symptoms. Most patients with primary HPT today have mild, nonspecific symptoms, such as weakness, fatigue, and mental depression, and such signs as arterial hypertension and osteopenia, and detection of their hypercalcemia is generally serendipitous. The mildness and slow progression seen in many cases of primary HPT has resulted in much controversy about appropriate management.

Improved immunosuppressive regimens, better postoperative intensive care and judicious patient selection have all resulted in increased patient survival following orthotopic liver transplantation (OLT), which has become the preferred option for most patients with end-stage primary biliary cirrhosis (PBC). As with most other clinical series, PBC is now the most common indication for OLT in the King's College hospital and Cambridge programmes. To date (30 July 1990), 129 patients with PBC have been transplanted, with overall actual 1 and 5 year survival rates of 65 and 63% respectively. When patients transplanted since 1985 are considered, both the 1 and 2 year survival rates are 78%. Immediate operative mortality was 4.5%, generally due to uncontrollable bleeding, while further mortality within 30 days of operation--mainly consequent upon infection and multi-organ failure--has fallen from 40% prior to 1985 to 9% since 1988. Thirteen per cent of patients have been retransplanted for vanishing bile duct syndrome, manifest in this series invariably within the first 6 months following OLT. Although rehabilitation in this series was excellent, a significant percentage of cases have continuing problems with metabolic bone disease, hypertension and renal impairment, mainly due to cyclosporin toxicity.

The main objectives of medical and nutritional management of patients with chronic renal failure are to slow down the progression of renal disease and to prevent secondary complications due to hypertension, uremic metabolic disturbances, and bone disease. The importance of nutritional measures for this purpose is increasingly recognized. In the setting of vitamin D and calcium deficiency secondary hyperparathyroidism and retention of phosphate result in renal osteodystrophy. An increase in dietary calcium and avoidance of foods rich in phosphate are important. In some patients supplementation of vitamin D3 may be necessary while calcium homeostasis is monitored during follow up. The dietary protein content can influence the severity of the uremic state. Normal or increased consumption of protein may accelerate the progression of renal disease due to the accumulation of nitrogenous products. In addition, uremia itself may cause loss of appetite and thus accumulation of endogenous nitrogen compounds as a result of protein catabolism. Protein restriction under such circumstances may cause malnutrition and an associated increase in morbidity and mortality. Thus, dietary management must consist of individually designed restriction of total protein intake with ingestion of high value protein. This allows balanced nitrogen metabolism with a reduction in circulating uremic toxins.

11 cases of primary hyperparathyroidism were seen during 1975-1988. Follow up has varied from 1-10 years. Renal disease in the form of renal calculi and nephro-calcinosis was observed in nine cases (81.8%). Two presented in chronic renal failure and required dialysis. Bone disease was found radiologically in six patients (54.5%); two had bone cysts in multiple bones while all six had subperiosteal bone erosion. Hypertension was found in three patients (27.3%). Proximal myopathy was observed in two cases (18.1%). One patient each presented with hypercalcaemic crisis, chondrocalcinosis and acute pancreatitis. The calcification of blood vessels and cornea was seen in two cases.

A prospective cross-sectional study of 84 foot lesions in 50 diabetic patients was done in a Nigerian teaching hospital over a three-year period (1982-1984) to assess factors that may influence the choice of treatment and treatment outcome. Age, gender, duration of diabetes, mode of treatment of diabetes and tobacco smoking did not influence whether or not a diabetic with a foot lesion will have major amputation, an unsatisfactory outcome of primary treatment, prolonged hospital stay or will die. Similarly, the presence of foot infections alone, microangiopathy (nephropathy, retinopathy), foot ischaemia alone or neuropathy alone had no relationship to poor prognostic indices. However, when these complications appeared in concert (neuropathy, ischaemia and infection) and when, at presentation, there was associated systemic disease (as shown by anaemia and leucocytosis), severe fasting hyperglycaemia, evident bone destruction and anaerobic superinfection, the outcome of treatment was adverse. In addition, hypertension and infection of the foot were related to need for major amputation. Poor long-term control did not influence prognosis adversely. We therefore suggest that the high morbidity seen with diabetic foot lesions could be reduced by optimizing glycaemic control, using combination antibiotic chemotherapy, vigorously correcting anaemia and encouraging early presentation of even mild lesions before underlying bone disease supervenes.
