Two-hour post-dose cyclosporine levels in renal transplantation in Argentina: a cost-effective strategy for reducing acute rejection.

UNLABELLED: Monitoring of cyclosporine (microemulsion CsA) at 2 hours post-dose (C2), a measure of absorption and exposure, appears superior to trough (C0) monitoring for prediction of rejection risk. The purpose of this study was to determine whether C2 was cost-effective compared to C0 in Argentina. METHODS: A predictive decision model was adapted to Argentina to predict costs associated with C0 and C2 measurements in the first year after transplantation. Patients were treated with microemulsion CsA, steroids and azathioprine or MMF. Parameter estimates for the C0 strategy were based on event rates observed in published clinical trials. The model was adapted to Argentinean health system through local protocols and expert opinions; costs were valued in Argentinean pesos and converted to US dollars (1 USD = 2.85 ARS). RESULTS: Incidence of acute rejection was predicted to be 25.0% at 1-year among patients monitored by C0 and 18.0% by C2. Graft survival was predicted to be 1.4% lower in the C0 group. No important differences were identified in co-morbidity, C0 and C2 monitoring costs, and in ambulatory-based adverse events between C0 and C2 cohorts. The model predicted an average cost per patient of $16,269 for C0 and $16,343 for C2 testing (year 1). Sensitivity analyses indicated that the average daily dose of microemulsion CsA was the most important parameter leading to the incremental cost per patient. CONCLUSIONS: C2 is expected to provide a potentially important reduction in the risk of acute rejection without increasing the estimated cost of care in the first year post-transplant.

Diagnosing erectile dysfunction: instruments for endocrine diagnosis.

Endocrine factors represent an important and potentially treatable cause of sexual dysfunction. The availability of a correct endocrinological diagnosis allows correct identification of most cases of sexual dysfunction in which the endocrine apparatus is involved. Not only the most frequent causes of endocrine sexual dysfunction, such as hypogonadism and hyperprolactinaemia, but almost all extra-gonadal endocrinopathies (hyper-and hypothyroidism, hyper- and hypocortisolism, steroidal secreting tumours, etc.) may have importance to a greater or lesser extent in sexual function. It is, therefore, necessary that the diagnostic process for sexual dysfunctions of an endocrine nature be as integrated and wide as possible, especially as such pathologies are normally extremely responsive to medical or surgical therapy.

[Therapeutic efficacy of ursodeoxycholic acid in persistent gallbladder lithiasis and persistent biliary sludge: preliminary results of a multicenter experience].

A prospective and multicenter study was performed to determine the efficacy and tolerance of ursodeoxycholic acid (UDCA) in the treatment of gallstones and biliary sludge. Criteria for entry into the trial were radiolucent gallbladder stones; until 20 mm of size and visualization of the gallbladder by oral cholecystography. Too were treatment the patients with persistent biliary sludge (PBS) defined by the persistence of the biliary sludge in two consecutive echography along three months. Without severe gallbladder disease. Then daily UDCA doses of 600 mg were suminstred divided in two postprandial times for a six months period. The control to the treatment were: basal ultrasonography (US) of the gallbladder and by follow-up gallbladder US for six months; clinical examination every month and cholecystography before and after the treatment. Of 110 admitted patients, 19 (17%) stopped the treatment for no-medical reasons and 91 (83%) arrived to the and point. After six months of treatment, complete dissolution was observed in 50% of the patients (46/91), partial in the 43% (39/91) and failed the treatment in 6.5% (6/91) who presented high density stones for computed tomography, CT (greater than 60 UH). According to pattern of lithiasis dissolution was complete in 100% (22/22) of the patients with PBS; 71.4% (10/14) in microlithiasis and 25% (14/55) in macrolithiasis. Minor adverse effects were acidism in the 7.7% (7/91) and diarrhea in the 1.1% (1/91). In the other hand, one patient presented acute pancreatitis (1/91; 1.1%), it must be discussed if was a complication of the lithiasis or an therapeutic effect. The UDCA was a safe and effective treatment without lethality in PBS and in microlithiasis while in case of macrolithiasis must be standardized response criterion, for example density stones for CT.
