Twenty-four-hour ambulatory blood pressure measurement in a primigravid population.

Objective: To establish the profiles of 24-h non-invasive ambulatory blood pressure measurement (ABPM) during the trimesters of pregnancy and the puerperium in normotensive healthy primigravidae.

Design: A prospective study in which 24-h ABPM was performed on five occasions in each subject: in the first trimester between 9 and 16 weeks' gestation; in the second trimester between 18 and 24 weeks; in the third trimester between 26 and 32 weeks and between 33 and 40 weeks; and finally at 6 weeks post partum.

Method: One hundred and six Caucasian primigravid women who were normotensive at their first booking visit were recruited consecutively from the antenatal clinic and had 24-h ABPM performed with the SpaceLabs 90207 ambulatory system.

Comparative methylprednisolone pharmacokinetics in renal transplant patients receiving double- or triple-drug immunosuppression.

Objective: To assess the pharmacokinetics of chronic methylprednisolone therapy in renal transplant patients receiving double-drug (methylprednisolone and azathioprine) and triple-drug (methylprednisolone, azathioprine, and cyclosporine) immunosuppression.

Design: Parallel, randomized trial.

Patients: Fourteen renal transplant recipients (aged 29-65 y) evaluated in a public, university-affiliated hospital clinic.

Pharmacological manipulation of acute cyclosporin ischemic renal injury with trimetazidine.

Cyclosporin has had a major impact on organ transplantation, but associated nephrotoxicity is a significant problem. Renal hypothermia, a known anti-ischemic maneuver, limits cyclosporin-ischemic renal failure. Pharmacological manipulation with an anti-ischemic agent, such as trimetazidine, may prevent cyclosporin nephrotoxicity.

Lower prevalence of anti-hepatitis C antibody in dialysis and renal transplant patients in Ireland.

It is well recognised that haemodialysis and renal transplant patients are at increased risk of developing non-A, non-B hepatitis. Recently the genome of hepatitis C virus (HCV), the major causative agent for non-A, non-B hepatitis, has been isolated. Anti-HCV seroprevalence was assessed in all haemodialysis patients (266) in Ireland who in March 1990 had been dialysed for at least 6 months.

Chelation treatment of neurological Wilson's disease.

The results of chelation treatment of 137 patients presenting with neurological Wilson's disease are described, together with the more commonly observed toxic reactions to the various drugs employed. Fifty-seven patients made an excellent response to treatment and became symptom free. Thirty-six patients made a good recovery, but were left with some minor neurological deficit.

Older donors and kidney transplantation.

Reluctance to use kidneys from older donors (> 50 years of age) is based on reports of inferior results. We reviewed our experience with 45 kidneys transplanted from older donors. Primary nonfunction, immediate graft function, and 1-, 2- and 3-year graft survival rates were similar to those obtained with kidneys transplanted from donors aged between 20 and 40 years.

The use of recombinant human erythropoietin in end stage renal disease.

We treated 57 patients who suffered from end stage renal disease (ESRD) with recombinant human erythropoietin (EPO) for a mean period of 56 weeks. Patients were aged between 18 and 81 years. Forty three patients were on haemodialysis and 14 on continuous ambulatory peritoneal dialysis (CAPD).

Cytomegalovirus infection as a complication of OKT3 therapy in kidney transplant recipients.

We compared the incidence of clinical CMV illness in 25 renal transplant recipients treated with OKT3 for steroid resistant cellular rejection with 88 renal transplant patients treated only with conventional immunosuppression (cyclosporin A and steroids). Nine (36%) patients in the OKT3 group developed CMV illness compared to (2.3%) amongst those treated conventionally (p < 0.

Wilson's disease: the problem of delayed diagnosis.

To discover the earliest symptoms and signs of neurological Wilson's disease we analysed the case histories of 136 patients who were seen between 1955-87: patients with hepatic or presymptomatic Wilson's disease were excluded from this series. Thirty one patients (23%) gave a history of an episode of liver damage. The onset of symptoms ranged from nine to 40 years with a median of 16.

Characteristics of bacteriuria in a homogeneous maternity hospital population.

Bacteriuria and urinary tract infection are a common cause of morbidity in pregnancy. Recent evidence has, however, questioned the magnitude of this risk and the effectiveness of therapy in reducing it. To clarify matters, a prospective study on 3123 ante-natal women was carried out.

Clinical application of ambulatory blood pressure measurement in pregnancy.

Eclampsia and pre-eclampsia are the most important obstetric causes of maternal mortality in the Western world. The current definitions of hypertensive disorders in pregnancy rely on arbitrary blood pressure limits based on intermittent clinic readings which are subject to bias and error. Twenty-four-hour ambulatory blood pressure monitoring can overcome many of these deficiencies but has only recently been introduced into antenatal care.

Prevention of cyclosporine enhanced ischaemic renal injury using induced hypothermia.

Cyclosporine is associated with an increased incidence of graft primary non function and poorer long term graft function in patients with prolonged ischaemia times. We evaluated the role of hypothermia in preventing this synergism between the nephrotoxic effects of cyclosporine and ischaemia in a canine model. Induced renal hypothermia prevented this synergism.

A canine model of cyclosporine enhanced ischemic renal injury.

Clinical reports of increased graft primary non function in patients receiving cyclosporine in whom the anastomosis time is prolonged (greater than 30 minutes) suggest a synergism between the nephrotoxic effects of cyclosporine and the ischaemia occurring during transplantation. Using unilaterally nephrectomised greyhound dogs, sixty minutes ischaemia and cyclosporine 10 mg./kg.

Transplantation of kidneys from pediatric cadaver donors to adult recipients.

Pediatric donors (less than 12 years old) are a potentially important source of kidneys for adult recipients. Previous reports of decreased graft survival and increased complication rates have made surgeons wary of using such kidneys. In 64 kidneys from younger donors transplanted to adult recipients the delayed graft function rate (41 versus 42%), and 2 and 3-year graft survival rates (67 versus 72% and 61 versus 65%, respectively) were similar to those seen with kidneys from adult donors.

Liver copper concentration in Wilson's disease: effect of treatment with 'anti-copper' agents.

Serial copper determinations have been made on the livers of 10 patients with Wilson's disease. Two were studied before and eight after the start of treatment in order to assess the effect, if any, on the concentration of the metal. In two patients who were receiving no therapy and in one in whom it had been discontinued, the level of copper rose.

Clinical and histopathologic findings in adults with the nephrotic syndrome.

The clinical and histopathologic findings in 225 Irish adults with nephrotic syndrome were reviewed. Membranous nephropathy was the most common lesion found (28%), followed by proliferative glomerulonephritis (17%), and focal sclerosing glomerulonephritis (16%). Minimal change disease was the least frequent cause for idiopathic nephrotic syndrome (12%).
