Background and aims
Leptin (LPT) is associated with unfavourable cardio-metabolic risk profile. Although a number of studies have found a positive association between LPT and insulin resistance (IR), no observational study has evaluated a prospective association to detect a predictive role of LPT in IR. Therefore, the aim of this study was to estimate the role of LPT on the incidence of IR in an 8-year follow-up of a sample of adult men (The Olivetti Heart Study).Methods and results
The study included 527 not diabetic men without IR (homeostasis model assessment - HOMA index < 2.77 UI) at baseline. Baseline LPT was significantly and positively associated with HOMA index, body mass index (BMI), waist circumference and blood pressure. At the end of the 8-year follow-up period, a positive and significant association was detected between baseline LPT and changes in HOMA index (r = 0.25, p < 0.01) and incidence of IR (OR: 2.6, 95%CI: 1.9–3.4). This trend was also confirmed after adjustment for potential confounders. In addition, the predictive value of LPT was found in subjects who had not experienced any weight increase over the years, and for normal weight and excess body weight participants, separately.Conclusions
The results of this prospective study suggest a predictive role of circulating LPT levels on a reduction of insulin sensitivity over time, independently of main potential confounders, in non-diabetic men without IR at baseline. In addition, in normal weight individuals, LPT levels were associated with development of IR. 相似文献2.

A 26-year-old man with AIDS-related complex (ARC) was treated with high-dose busulphan and cyclophosphamide, followed by allogeneic bone marrow transplantation. For 3 months before transplantation he received a combination of four drugs considered active against human immunodeficiency virus (HIV) to reduce the viral burden: zidovudine, acyloguanosine, fusidic acid and phenylidantoin. Although in reduced doses in coincidence with marrow engraftment, zidovudine therapy was scheduled after transplantation in order to protect donor cells from infection with HIV. Engraftment rapidly occurred and was documented by cytogenetic analyses. The post-transplant course was characterized by severe acute GvHD with irreversible hepatorenal failure. The patient died on day 48 after transplantation. Polymerase chain reaction analyses for detecting HIV DNA showed the persistence of positivity at day +30 and +45 after transplantation. Antibodies to specific HIV proteins evaluated with Western blot testing also persisted at days +21 and +35 after transplantation. Circulating immunocomplexes disappeared on day +31, and an increase in the CD4/CD8 ratio occurred. The short survival of the patient, affected by chronic hepatitis too, does not allow final conclusions about the role of BMT in HIV disease. 相似文献

Genes of the renin-angiotensin-aldosterone system (RAAS) are natural candidates for sodium homeostasis and blood pressure regulation. To investigate the effect of a combination of polymorphisms of RAAS genes on renal sodium handling and blood pressure, 918 participants to the Olivetti Heart Study were genotyped for the following polymorphisms: I/D of angiotensin converting enzyme (ACE), M235T of angiotensinogen (AGT), A1166C of angiotensin II type-1 receptor (AT1R), and C-344T of aldosterone synthase (CYP11B2). The segmental renal sodium handling was evaluated by the fractional excretions of exogenous lithium (FE-Li), uric acid (FE-UA), and sodium (FE-Na). Twenty-eight carriers of triple homozygosity for M (AGT), A (AT1R), and C (CYP11B2) in the presence of the D allele of ACE (DD/ID) showed lower FE-Li (20.0%+/-5.9% versus 25.0%+/-7.5%; P=0.004; mean+/-sD), FE-UA (6.3%+/-2.0% versus 8.2%+/-2.7%; P=0.001), and FE-Na (0.96%+/-0.41% versus 1.22%+/-0.61%; P=0.004) as compared with all other allelic combinations (n=890), independently from age and body mass, suggesting an enhanced rate of proximal tubular sodium reabsorption. The carriers of the MM, AA, CC, DD/ID combination showed a substantially higher probability of being hypertensive (OR: 3.4 [(99% CI: 1.1 to 10.1]), independently of age and body mass. This relatively rare combination of allelic variants of candidate genes of the RAAS is associated with a significant alteration in proximal renal sodium handling and with higher risk of hypertension, suggesting that a combination of polymorphic variants at different candidate loci may affect phenotypic expression even in the absence of detectable effects of each variant at any single locus. 相似文献

ObjectiveAs excess sodium and inadequate potassium intake are causally related to hypertension and cardiovascular disease, the MINISAL-GIRCSI Program aimed to provide reliable estimates of dietary sodium and potassium intake in representative samples of the Italian population.Design and methodsRandom samples of adult population were collected from 12 Italian regions, including 1168 men and 1112 women aged 35–79 yrs. Electrolyte intake was estimated from 24 hour urine collections and creatinine was measured to estimate the accuracy of the collection. Anthropometric indices were measured with standardised procedures.ResultsThe average sodium excretion was 189 mmol (or 10.9 g of salt/day) among men and 147 mmol (or 8.5 g) among women (range 27–472 and 36–471 mmol, respectively). Ninety-seven % of men and 87% of women had a consumption higher than the WHO recommended target of 5g/day. The 24 h average potassium excretion was 63 and 55 mmol, respectively (range 17–171 and 20–126 mmol), 96% of men and 99% of women having an intake lower than 100 mmol/day (European and American guideline recommendation). The mean sodium/potassium ratio was 3.1 and 2.8 respectively, i.e. over threefold greater than the desirable level of 0.85. The highest sodium intake was observed in Southern regions. Sodium and potassium excretion were both progressively higher the higher the BMI (p < 0.0001).ConclusionsThese MINISAL preliminary results indicate that in all the Italian regions thus far surveyed dietary sodium intake was largely higher and potassium intake lower than the recommended intakes. They also highlight the critical association between overweight and excess salt intake. 相似文献

Five immunocompromised patients, four with AIDS and one who had undergone bone marrow transplantation, showing ocular signs of cytomegalovirus retinitis, were treated with 9-(2-hydroxy-1-(hydroxymethyl)ethoxymethyl) guanine (Ganciclovir), given intravenously at the dose of 5 mg/kg twice daily for a period ranging from 10 to 20 days. At the end of the treatment, in 4 of 5 patients, the ophthalmoscopic picture had improved, with reduced exudation and an arrest in the progression of retinal necrosis, the pattern clearly indicating a trend towards organization and scarring. Complete resolution of the retinitis without subsequent relapse was observed only in the bone marrow transplant patient, who recovered immunologically, whereas improvement of the eye involvement was only transient in the three AIDS patients. 相似文献

Two hundred and eighty-four febrile episodes in immunocompromised patients were treated with ceftriaxone alone or in combination with amikacin. In the ceftriaxone-treated group, 60 out of 143 febrile episodes were microbiologically documented, while in the group receiving the combination therapy, there were 32 out of 140 (p = 0.0007). Gram-positive microorganisms were more common than gram-negative ones, accounting for 59 of the 101 isolated bacteria. The ceftriaxone regimen appeared to have a response rate comparable to the combination regimen (73.91 vs. 78.88%). Superinfections occurred under both regimens. 相似文献

Two episodes of meningitis due to penicillin-resistant Streptococcus pneumoniae occurring in two patients with chronic graft-versus-host disease (GVHD) are reported. Both patients were treated with ceftazidime. The first patient died, unresponsive to therapy. The second patient showed clinical improvement, reverting to her baseline mental status. This report draws attention to the fact that in chronic GVHD patients: (1) bacterial prophylaxis does not ensure protection against encapsulated bacteria; (2) rapid microbiological investigation is recommended with any upper respiratory tract infections. 相似文献

The present study was designed to investigate whether non-insulin-dependent diabetic hypertensive patients exhibit abnormalities in intracellular sodium metabolism similar to those described for essential hypertensive patients. Both normotensive and hypertensive non-insulin-dependent diabetic patients had similar average values of both Na+-Li+ countertransport and Na+-K+ cotransport compared with nondiabetic controls. Within the group of diabetic patients, hypertensive patients did not exhibit any abnormalities in either of the sodium transport pathways studied. The possible implications of these findings are addressed. 相似文献

We have evaluated the azlocillin-amikacin combination, given at a daily dose of 200 mg/kg and 15 mg/kg respectively, in the treatment of 62 consecutive febrile granulocytopenic patients (less than 500 PMN/microliters) affected by hematological disease. The effectiveness of the treatment was assessed in 60 patients, 44 (73%) of whom responded within 96 hours from the beginning. 36 of the responders showed microbiological and clinical infections, 2 had clinically documented pneumonia and 6 a possible infection. No improvement was obtained in 16 patients; 7 of whom suffered from clinical and microbiological infection, 2 from pulmonary mycosis, 4 from possible infection and 3 from doubtful infection. Seven of these patients subsequently responded to a proven antibiotic treatment, while only one of the remaining responded to a second-line empirical antibiotic schedule. These results suggest that the combination of azlocillin-amikacin was able to overcome about two-thirds of the infections, representing an effective remedy for the empiric treatment of febrile neutropenic patients. 相似文献
