Abstract

Skeletal muscle wasting is a significant problem in elderly and debilitated patients. Growth hormone (GH) is an anabolic growth factor for skeletal muscle but is difficult to deliver in a therapeutic manner by injection owing to its in vivo instability. A novel method is presented for the sustained secretion of recombinant human GH (rhGH) from genetically modified skeletal muscle implants, which reduces host muscle wasting. Proliferating murine C2C12 skeletal myoblasts stably transduced with the rhGH gene were tissue engineered in vitro into bioartificial muscles (C2-BAMs) containing organized postmitotic myofibers secreting 3-5 microg of rhGH/day in vitro. When implanted subcutaneously into syngeneic mice, C2-BAMs delivered a sustained physiologic dose of 2.5 to 11.3 ng of rhGH per milliliter of serum. rhGH synthesized and secreted by the myofibers was in the 22-kDa monomeric form and was biologically active, based on downregulation of a GH-sensitive protein synthesized in the liver. Skeletal muscle disuse atrophy was induced in mice by hindlimb unloading, causing the fast plantaris and slow soleus muscles to atrophy by 21 to 35% ( < 0.02). This atrophy was significantly attenuated 41 to 55% (p < 0.02) in animals that received C2-BAM implants, but not in animals receiving daily injections of purified rhGH (1 mg/kg/day). These data support the concept that delivery of rhGH from BAMs may be efficacious in treating muscle-wasting disorders.

Abstract

The efficacy and safety of trandolapril alone and in combination with a calcium channel blocker were evaluated in 13,147 hypertensive patients over 60 years old. Two patient groups were constituted. After a 2-week wash-out period, the patients in group I received monotherapy with trandolapril 2 mg/day for 4 weeks. Trandolapril was continued for another 4 weeks in responding patient, otherwise the dosage of trandolapril was doubled or another antihypertensive was added. Group 2, composed of patients previously treated with a calcium channel blocker with insufficient efficacy, was treated according to the same treatment regimen, but the calcium channel blocker was maintained throughout the study. 13,147 patients (group 1: 11,329 patients, group 2: 1,818 patients) with a mean age of 68 +/- 7 years were followed. After 4 weeks of treatment, the blood pressure measured by mercury sphygmomanometer decreased from 176 + 11/99 +/- 8 mmHg to 164 +/- 12/87 +/- 7 mmHg (p0.0001). This blood pressure fall was similar in group 1 (-22 +/- 12/-12 +/- 8 mmHg) and in group 2 (-21 +/- 11/-12 +/- 8 mmHg). In the pure systolic HT subgroup treated by trandolapril monotherapy, the antihypertensive effect predominantly affected the SBP (-23 +/- 12/- 4 +/- 6 mmHg). The antihypertensive effect was correlated with the initial blood pressure. In group 1, in the case of insufficient response to trandolapril monotherapy, the addition of a calcium channel blocker was the strategy which achieved the most marked antihypertensive effect (ANOVA, p0.0001). This bitherapy was more effective than the trandolapril+diuretic combination (-18 +/- 11/- 11 +/- 8 mmHg and -15 +/- 10/- 9 +/- 7 mmHg, respectively (p0.001). A total of 1,270 adverse events were reported by 996 patients (7.6%), leading to discontinuation of treatment in 372 patients (2.8%). The most frequent adverse effects were cough (2.8%), headache (0.8%), vertigo (0.8%) and nausea (0.5%). Only one minor equivalent of angioneurotic oedema was reported. In conclusion, trandolapril is effective and well tolerated in elderly hypertensive patients. In the case of pure systolic HTA, its action is essentially exerted on SBP. The combination of trandolapril+calcium channel blocker appears to be the most effective strategy in the case of incomplete blood pressure control by trandolapril alone.
