A questionnaire survey and review of the literature show that pregnancy can be well tolerated in most women with renal transplants. Fifty-two per cent of the renal transplant recipients who became pregnant had full-term infants with no serious complications. With therapeutic abortions, excluded, 71% of the 308 pregnancies permitted to continue resulted in full-term infants. Rejection episodes were occasionally a serious problem, occurring in 9% of the pregnancies. Mechanical interference with renal excretion or preventing vaginal delivery occurred in 5.6% of the cases. Hypertension and proteinuria, often existing prior to pregnancy, became frequently increased during pregnancy. Infections not associated with rejection were common but easily controlled in most cases. Prematurity was frequent but related to renal function and the time interval from transplant to conception. The most serious infant complications were related to prematurity. Unknown is the future of these infants and their progeny because of their intrauterine exposure to immunosuppressive drugs.

An analysis was carried out of the mortality rate on the medical wards of the University College Hospital, Ibadan, over a 14-year period (1960-73). A total of 4,568 cases were reviewed with an annual death rate of between 300 and 400. Most of the deaths resulted from cardiovascular diseases, especially hypertension, the mortality rate from which has shown no appreciable decline over the years. Death from cerebrovascular accident is steadily increasing. Infections contribute considerably to mortality from chest and alimentary tract disease, although there has been a progressive decline in mortality rates from infectious diseases such as tetanus and typhoid fever. The standard of death certification needs to be improved upon, especially with respect to the clarification of the primary and the contributory causes of death and whether post-mortem examination was carrie dout or not. It is suggested that more effort should be made to ensure that post-mortem examination is carried out in cases where there is doubt about the ante-mortem diagnosis unless such a request is specifically refused by the relatives of the deceased after explaining to them the value of such an examination to medical knowledge.

We address the question of whether or not age and comorbidity are related to intra- and postoperative complications after a transurethral resection. The data are derived from a retrospective, population-based study conducted in Hagen, Germany, which included all patients with an initial prostatectomy for benign prostatic hyperplasia (N = 621) during the five-year period 1984-1988. Seventy-seven percent of the patients had at least one of the following preoperative risk factors: heart disease, hypertension, smoking, chronic obstructive lung disease, and diabetes. There was no intraoperative death. The risk of intraoperative circulatory complications was found to be related to age only for patients without a history of heart diseases or hypertension. The incidence of major complications was 3.1 percent and was significantly higher in the oldest age group. Three patients (0.54%) died postoperatively in the hospital. Infections were the most frequent postoperative complications. The relationship of age and overall postoperative complications was not statistically significant either for patients with (p = 0.121) or without any comorbidity (p = 0.651). Based on this study it seems reasonable to conclude that age is not a clinically relevant risk factor for perioperative complications in patients who have a transurethral resection for benign prostatic hyperplasia.

Liver transplant is the first therapeutic choice in most of the advanced liver diseases. Nevertheless, its performance originates a number of complications derived from: a) conservation techniques of the organ (in our study a prolonged time of hot ischemia was significantly associated with); b) surgery (all patients who required massive blood transfusions developed metabolic alkalosis); c) the graft itself (all the F 1. degrees were significantly infected), and d) extrahepatic causes (cyclosporin was responsible for high blood pressure and nephrotoxicity which appeared as oliguria with good response to furosemide, as well as hyperglycemia). Some other relevant results in our series were: right pleural effusion and thrombopenia which appeared with a high incidence. Infections were usually originated the staphylococcus which grows in half of the cultures. We also want to highlight the short mean stay and the low mortality incidence in the ICU.

This is a review of the side-effects of cyclosporin A (CyA) in patients with severe psoriasis; renal dysfunction and hypertension are discussed elsewhere. In particular, paraesthesia, hypertrichosis, gingival hyperplasia and gastrointestinal disorders may occur, but are generally transient, mild-to-moderate in severity and only rarely require discontinuation of CyA. Infections are not a problem. As expected with an immunosuppressive drug, there is the possible risk of tumour development, particularly squamous cell carcinomas. However, these skin malignancies developed almost exclusively in patients previously treated with PUVA and/or methotrexate. The few lymphoproliferative disorders regressed spontaneously on discontinuation of the drug. Whether the isolated cases of solid tumours were CyA-related is not known. Apart from a raised serum creatinine, an important indicator of renal dysfunction, the laboratory abnormalities included hypomagnesaemia, hyperkalaemia, increased uric acid, changes in liver function tests, and fluctuations in the serum cholesterol and triglyceride levels. Although most of these changes were not clinically relevant, laboratory monitoring of patients with psoriasis treated with CyA is essential.

From 1982 to 1987 sixty-three children were treated with cyclosporin A and low dose prednisolone after kidney transplantation. Patient survival rate at 4 years after transplantation was 98.3%, survival rate of living related grafts 100% (n = 10), and survival rate of cadaveric grafts 73% (n = 53). Adequate cyclosporin blood levels were achieved in all children with a dosage regimen related to body surface area. Major concerns during the observation period were the loss of glomerular filtration rate from 51.8 to 40.5 ml/min/1.73 m2, a hypertension rate of 77.8%, and hyperuricemia. Cyclosporin A-side effects were mild. Infections occurred in 11.1%. Growth retardation in prepubertal children improved by 0.74 standard deviations of normal height, and in pubertal children by 0.51. We conclude that cyclosporin A treatment in children enables excellent long term graft survival rates with improved growth rehabilitation, however, the prevention of the cyclosporin associated nephrotoxicity and hypertension remains the major problem.

The role of preceding infection as a risk factor for ischaemic stroke was investigated in a case-control study of 54 consecutive patients under 50 years of age with brain infarction and 54 randomly selected controls from the community matched for sex and age. Information about previous illnesses, smoking, consumption of alcohol, and use of drugs was taken. A blood sample was analysed for standard biochemical variables and serum cholesterol, high density lipoprotein cholesterol, triglyceride, and fasting blood glucose concentrations determined. Titres of antimicrobial antibodies against various bacteria, including Staphylococcus, Streptococcus, Yersinia, and Salmonella and several viruses were determined. Febrile infection was found in patients during the month before the brain infarction significantly more often than in controls one month before their examination (19 patients v three controls; estimated relative risk 9.0 (95% confidence interval 2.2 to 80.0)). The most common preceding febrile infection was respiratory infection (80%). Infections preceding brain infarction were mostly of bacterial origin based on cultural, serological, and clinical data. In conditional logistic regression analysis for matched pairs the effect of preceding febrile infection remained significant (estimated relative risk 14.5 (95% confidence interval 1.9 to 112.3)) when tested with triglyceride concentration, hypertension, smoking, and preceding intoxication with alcohol. Although causality cannot be inferred from these data and plausible underlying mechanisms remain undetermined, preceding febrile infection may play an important part in the development of brain infarction in young and middle aged patients.

Between March, 1985 and April, 1987, 25 orthotopic heart transplantations were performed in 20 men and 5 women aged from 17 to 58 years (mean 42 years) on account of cardiomyopathy (n = 15), ischaemic heart disease (n = 6) or miscellaneous lesions (n = 4). The immunosuppressive treatment consisted of antilymphocyte serum and corticosteroids during 10 days; cyclosporine was introduced on the 7th day and continued thereafter in association with low-dose corticosteroid therapy. Endomyocardial biopsies were performed. Acute rejection, responsible for 2 deaths (one on the 10th day, the other in the 10th week), usually occurred within the first 3 months. Infections were frequent and often serious, resulting in one death in the 7th week. One out of patients had to be treated for arterial hypertension, and 3 patients presented with renal impairment (blood creatinine over 200 mumoles/l). The actuarial survival rate at 2 years is 84 p. 100. More than one-half of the patients have resumed social and occupational activities.

162 children with infantile spasms were treated with ACTH at the Children's Hospital, Helsinki, and at the Aurora Hospital, Helsinki, during 1960--76. In a large proportion (37%) of the children the treatment caused pronounced side effects, and the mortality was 4.9%. The most common complications were infections: septic infections, pneumonias, and urinary and gastrointestinal infections. Other side effects were arterial hypertension (11), osteoporosis (2), hypokalaemic alkalosis (2), and other marked electrolyte disturbances (10). In children necropsy showed fresh intracerebral haemorrhages. Four children developed oliguria and hyperkalaemia during and after withdrawal of ACTH. One of them had tubular necrosis confirmed by renal biopsy. Infections were significantly more common with large doses (120 units) of ACTH than with small ones (40 units). It is concluded that side effects, even severe ones, are more common during treatment than had been assumed. Careful watch is important before and after treatment. The benefit of very high dosages should also be reconsidered.

FK 506 was compared with cyclosporin in a randomised trial in good-risk cadaveric renal transplant recipients. The objective was to evaluate whether oral FK 506 dosing was viable and whether blood concentrations in the range 10-20 ng/ml would prove to be practical. Thirty-one adult patients were randomised to FK 506 and 16 to cyclosporin. Both groups received an identical regimen of azathioprine and corticosteroids. Serum creatinine concentrations decreased rapidly in both groups with mean values below 200 mumol/l within 2 weeks. One graft in the cyclosporin group was lost due to renal vein thrombosis. During the 6-week study period, 19.4% of patients on FK 506 and 31.3% on cyclosporin experienced acute rejection. One patient in each group experienced corticosteroid-resistant rejection that responded to anti-lymphocyte therapy. Infections were reported in 51.6% of the FK 506 group compared with 37.5% of the cyclosporin group. The spectrum of adverse events was similar in both groups. However, minor neurological disorders were more common in the FK 506 group (54.8% versus 6.3%) whereas hypertension was less common (48.8% versus 75.0%). The results indicate that oral FK 506 rapidly achieves therapeutic blood concentrations and is an effective immunosuppressant for the initial treatment of renal allograft recipients.
