CMV disease (CMVD) is a recognized problem of the early post-transplant period (PTP) in renal transplant recipients. Information on CMVD in the late (< 2 years) PTP is scarce. We have observed 5 cases of CMVD during late (3–8 years) PTP during the last 15 years. Three of these patients died from CMVD. One of the patients with late-onset CMVD recovered spontaneously from mild pneumonitis, 1 patient with severe CMVD after therapy with ganciclovir/anti-CMV-IgG. CMVD was ascribed to primary infection in 4/5 patients, and transmission was attributed to blood products in 2 cases. At the time of CMVD, 4/5 patients were on stable immunosuppression with azathioprine/prednisone; 1 patient who died had received prednisone pulses 1 month prior to CMVD. Late onset CMVD is an underreported disease in renal transplant recipients, which warrants preventive measures and consideration of antiviral therapy.
1. Adults with growth hormone deficiency have an abnormal body composition. Alterations in body composition are closely related to substrate concentrations and insulin action. The lack of growth hormone has been associated with increased insulin sensitivity. 2. We investigated the correlations of body composition with fasting insulin levels and substrate concentrations in 24 adults with growth hormone deficiency over a wide range of adiposity (body mass index 18.8-42.3 kg/m2). 3. Lean body mass was measured by total body potassium, computer tomography of the thigh and urinary creatinine excretion. Muscle fibre distribution was evaluated from vastus lateralis biopsies. Fat mass was assessed by skinfold thickness measurements, computer tomography of the thigh, and waist and hip girth. 4. Fasting plasma insulin level increased with fat mass (r = 0.67, P = 0.0004) and with waist girth (r = 0.76, P = 0.0001). Fasting plasma insulin level increased with fasting plasma glucose level (r = 0.53, P = 0.01). Fasting plasma glucose level in turn was positively correlated with lean body mass (r = 0.49, P = 0.01) and with total thigh muscle area (r = 0.54, P = 0.01). There was no correlation between lean body mass and fat mass (r = 0.17, not significant) nor between muscle fibre types and fat mass or fat distribution. Fasting plasma insulin level showed no correlation with any measurement of lean body mass or muscle fibre type. 5. These data demonstrate that the presence of obesity is associated with hyperinsulinaemia as the result of insulin resistance in adults with growth hormone deficiency, which could contribute to the increased cardiovascular mortality in adults with growth hormone deficiency.
Analysen des Säure-Basen-Status des Liquors cerebrospinalis sind methodisch schwierig, da schon bei kurzer Lagerzeit O2 eintritt, CO2 entweicht und der pH ansteigt. An 50 Patienten wurden mit Verarbeitungszeiten unter 20 Sekunden Säure-Basen-Befunde des Liquors cerebrospinalis erhoben. Die daraus resultierenden Normalwerte (pH 7,298 ± 0,007; pCO2 46,94 ± 4,84 mmHg; HCO3 22,78 ± 2,15 mVal/l; BE -2,4 ± 2,39 mVal/l; pO2 50,27 ± 14,06 mmHg) zeigen, daß der Liquor saurer ist als oft in Diskussionen angenommen. Dieser Befund ist unter anderem wichtig für die Frage der Löslichkeiten intrathekal verabreichter Lokalanästhetika.
The histology of needle biopsy specimens of skeletal muscle from the vastus lateralis was quantitatively assessed in a group of adults with growth hormone (GH) deficiency, most of whom had hypopituitarism treated with conventional pituitary hormone replacement. The mean age of the 21 patients (16 males and 5 females) was 39 ± 2 (SEM). Comparisons were made with age-and sex-matched controls following six months double-blind, placebo-controlled treatment with recombinant human GH (rhGH) in the GH-deficient patients. Before treatment, needle muscle biopsies from patients with GH deficiency showed mean type I and II fibre areas of 5,153 ± 273 and 4,828 ± 312 µm2 respectively, which did not differ from the controls (4,482 ± 306 and 4,699 ± 310 µm2). Percentages of type I fibres were similar in the two groups (47.2 ± 2.5% in GH deficiency and 45.3 ± 2.2% in controls). No difference in the variability of type I or II fibre areas was demonstrated between the groups. Correlations between the relative contribution to total fibre area by type I fibres (mean fibre area × percent) and maximal oxygen uptake (p = 0.006), and between type II fibres and quadriceps force (p = 0.035) were noted in GH-deficient adults before treatment. Following rhGH treatment, no change was noted in mean fibre areas, variability of fibre areas, or percentage of either fibre type. We conclude that in adults with GH deficiency: (a) no consistent histological evidence of myopathy was seen; (b) qualitatively, the muscle fibres function similarly to normal, and (c) rhGH treatment does not result in any detectable change in fibre areas or proportion.
1. In adult humans with growth hormone deficiency, treatment with growth hormone has recently been shown to have major anabolic effects and to improve exercise performance. The cardiovascular effects of growth hormone in adults with growth hormone deficiency were examined in 24 patients treated with recombinant human growth hormone (0.07 units/kg at night) in a double-blind, placebo-controlled trial lasting 6 months. 2. Compared with placebo, resting M-mode echocardiography showed increases in left ventricular end-diastolic dimension and stroke volume in the group treated with recombinant human growth hormone. No differences were noted between the groups with respect to left ventricular end-systolic dimension, fractional shortening, wall thicknesses or mean arterial blood pressure. Left ventricular myocardial mass increased in the group given recombinant human growth hormone. 3. The supine plasma renin activity was increased and remained elevated over the 6 months, whereas the plasma aldosterone concentration was unchanged, after treatment with recombinant human growth hormone. Clinical signs of sodium retention were evident during the first 3 months of treatment with recombinant human growth hormone. 4. We conclude that treatment with recombinant human growth hormone in adults with growth hormone deficiency resulted in small increases in left ventricular pre-load, due to the sodium-retaining action of growth hormone. Activation of the renin-aldosterone system was involved in such changes. Myocardial hypertrophy was observed without changes in mean arterial pressure, reflecting the anabolic action of growth hormone.
