Factors that influence Italian consumers' understanding of over-the-counter medicines and risk perception.

OBJECTIVE: To evaluate information needs for safe self-medication we explored the Italian consumers' functional health literacy, specific knowledge and risk awareness about over-the-counter (OTC) medicines. METHODS: A survey was conducted in the health sections of six large super stores. Data were collected from a convenience sample of 1.206 adults aged 18 years and older through a self-administered questionnaire. RESULTS: Around 42% confused the concept of "contraindications" with that of "side effects" and were unable to calculate simple dosages. Most respondents were aware of the OTC general potential for side effects but 64.3% did not know that people with high blood pressure should use painkillers with cautions and 14.0% and 20.0% were unaware of the risks of long-term use of laxatives and nasal decongestants respectively. Higher total scores were obtained from women, highly educated people and those citing package leaflets as information sources. CONCLUSION: The study, the first of this type in Italy, showed an incomplete awareness of several risk areas, with regard to drug interactions and misuse/abuse. PRACTICE IMPLICATIONS: The results of this study were the basis of a following intervention plan tailored to the observed consumer needs and including information tools for customers and courses for the retail pharmacists.

Patterns of failures in endometrial cancer: clinicopathological variables predictive of the risk of local, distant and retroperitoneal failure.

UNLABELLED: The aim of this study was to assess the pattern of failure and the outcome of endometrial cancer patients and to analyze the variables predictive of the risk of local, distant and retroperitoneal lymph node disease recurrence. PATIENTS AND METHODS: The authors assessed 511 patients who underwent primary surgery. The median follow-up of survivors was 74 months. Peritoneal, hematogenous and lymph node recurrences outside retroperitoneal area were considered as distant failures. RESULTS: Tumor relapsed in 83 (16.2%) patients. Median time to recurrence was 18.5 months (range, 3-129 months). The relapse was local in 13 cases, distant in 37, retroperitoneal in 22, and involved both distant and other sites in 11. Logistic regression showed that cervical involvement was the only independent predictor of local recurrence. Tumor grade, lymph-vascular space involvement (LVSI) and myometrial invasion were independent predictors of distant failure. Lymph node status and tumor grade were independent predictors of retroperitoneal recurrence. Five- and 10-year overall survival rates were 87.1% and 79.5%, respectively. Patient age, lymph node status, cervical involvement, tumor grade, LVSI and myometrial invasion were independent prognostic variables for overall survival. CONCLUSION: Cervical involvement was an independent predictor of local recurrence, LVSI and myometrial invasion were independent predictors of distant failure, lymph node status was an independent predictor of retroperitoneal relapse, and tumor grade was an independent predictor of both distant and retroperitoneal recurrence. The identification of risk factors for different patterns of failure can be useful in better tailoring adjuvant treatment.

Pretreatment platelet and hemoglobin levels are neither predictive nor prognostic variables for patients with locally advanced cervical cancer treated with neoadjuvant chemotherapy and radical hysterectomy: a retrospective Italian study.

BACKGROUND: To assess the predictive and prognostic values of pretreatment platelet and hemoglobin levels in patients with locally advanced cervical cancer who underwent neoadjuvant chemotherapy followed by radical hysterectomy. METHODS: The authors retrospectively assessed 140 patients with FIGO (International Federation of Gynecology and Obstetrics) stage IB2-IIB cervical cancer who underwent chemosurgical treatment. RESULTS: Median pretreatment platelet and hemoglobin levels were 272,000/µL and 12.5 g/dL, respectively. Fourteen patients achieved a pathologically complete response, and 26 had an optimal partial response, with an optimal pathological response rate of 28.6%. By univariate analysis, optimal pathological response rate was associated with well/moderately differentiated grade (P = 0.02) and platinum-/paclitaxel-based chemotherapy regimen (P = 0.04), but not with platelet and hemoglobin levels. Multiple logistic regression confirmed that tumor grade (odds ratio, 2.827; 95% confidence interval [95% CI], 1.250-6.397; P = 0.01) and chemotherapy regimen (odds ratio, 5.416; 95% CI, 1.459-20.110; P = 0.01) were independent predictors of optimal pathological response. Five-year recurrence-free survival and 5-year overall survival were 66 % and 73%, respectively. By log-rank test, recurrence-free survival and overall survival were associated with pathological response (P = 0.0002 and P = 0.001), lymph node status, (P = 0.008 and P = 0.002), lymphovascular space status (P = 0.005 and P = 0.003), and parametrial and/or surgical margin status (P = 0.004 and P = 0.001), but not with platelet and hemoglobin levels. On multivariate analysis, pathological response (hazard ratio [HR], 7.999; 95% CI, 1.916-33.394; and HR, 6.007; 95% CI, 1.426-25.307) and parametrial and/or surgical margin status (HR, 2.061; 95%CI, 1.047-4.058; and HR, 2.561; 95% CI, 1.244-5.271) were independent prognostic variables of recurrence-free survival and overall survival. CONCLUSIONS: The achievement of an optimal pathological response is the strongest independent prognostic variable for patients with cervical cancer treated with neoadjuvant chemotherapy and radical hysterectomy, whereas pretreatment platelet and hemoglobin levels seem to be neither predictive of response to chemotherapy nor prognostic of long-term outcome.

The clinical outcome of epithelial ovarian cancer patients with apparently isolated lymph node recurrence: a multicenter retrospective Italian study.

OBJECTIVES: To assess the clinical outcome of epithelial ovarian cancer patients who developed an apparently isolated lymph node recurrence after primary therapy. METHODS: The authors retrospectively assessed 69 patients with epithelial ovarian cancer who were clinically or pathologically free of disease after primary therapy and who subsequently developed an apparently isolated lymph node recurrence. The median follow-up of survivors was 74.5 months. RESULTS: Median age was 58 years, FIGO stage was III-IV in 52 (75%) patients, residual disease after primary surgery was >1 cm in 36 (52%), first-line chemotherapy consisted of paclitaxel-/platinum-based chemotherapy in 44 (64%), time to recurrence was >12 months in 43 (62%), recurrence was pelvic and/or para-aortic in 41 (59%), and treatment at recurrence consisted of chemotherapy alone in 44 (64%), surgery plus chemotherapy in 22 (32%), surgery alone in one patient, surgery plus irradiation in one, and irradiation alone in one patient. Survival after recurrence was significantly related to the type of treatment (chemotherapy alone versus surgery plus chemotherapy, median: 20.8 months versus not reached, p=0.0002), and patient age (>58 versus <58 years, median: 26.8 versus 44.0 months, p=0.02). Overall survival was significantly related to the type of treatment (chemotherapy alone versus surgery plus chemotherapy, median: 45.4 months versus not reached, p=0.0001), patient age (>58 versus <58 years, median: 45.4 versus 62.9 months, p=0.03) and time to recurrence (<12 months versus >12 months, median: 45.4 versus 66.9 months, p=0.01). Cox model showed that treatment at recurrence was the strongest independent prognostic variable for both survival after recurrence (hazard ratio [HR]=0.277, p=0.0003) and overall survival (HR=0.249, p=0.0002). CONCLUSION: Patients who underwent surgery plus chemotherapy had a 72% reduction in the risk of death after recurrence and a 75% reduction in the risk of death after initial diagnosis when compared with those treated with chemotherapy alone. Secondary cytoreductive surgery appears to be able to prolong survival in epithelial ovarian cancer patients with apparently isolated lymph node recurrence.

Lymph-vascular space involvement and outer one-third myometrial invasion are strong predictors of distant haematogeneous failures in patients with stage I-II endometrioid-type endometrial cancer.

The aim of this retrospective study was to assess the predictive value of different clinicopathological variables (patient age, tumour size, FIGO grade, myometrial invasion, lymph-vascular space involvement [LVSI], invasion margins, peri-tumour phlogistic infiltrate and mitotic activity) for the risk of distant haematogenous recurrences in patients with endometrioid-type stage Ib-II endometrial cancer. Between August 1990 and April 2005, 259 patients had undergone laparotomy, peritoneal washing, total abdominal hysterectomy and bilateral salpingo-oophorectomy, with or without pelvic +/- para-aortic lymphadenectomy for endometrioid-type endometrial cancer. Thirty-six (13.9%) patients had developed recurrent disease after a median time of 17 months (range, 2-128 months). The relapse had been locoregional in 9, distant in 21 and both locoregional plus distant in 6 cases. This study assessed 12 patients with FIGO stage Ib-II disease who had developed distant haematogenous recurrences and 20 randomly chosen control patients with FIGO stage Ib-II disease who had remained recurrence-free after a median follow-up of 52 months (range, 37-66 months). Adjuvant therapy had been: no further treatment in 15 patients, external pelvic irradiation in 14 patients, adjuvant external pelvic irradiation plus brachytherapy in 2 patients and platinum-based chemotherapy followed by external pelvic irradiation in 1 patient. The site of distant failure had been the lung in 9 patients, liver in 2 patients and lung plus liver in 1 patient. A concomitant locoregional relapse (vagina or lymph nodes) had occurred in 3 patients. The median interval between surgery and the development of distant failure had been 16.5 months (range, 5-113 months). On univariate analysis, a higher incidence of FIGO grade 3 (50% versus 10%, p=0.0114), outer one-third myometrial invasion (91.7% versus 35.0%, p=0.0051) and LVSI (75.0.% versus 20.0%, p=0.0022) was found in the patients who had developed distant haematogeneous metastases compared to the recurrence-free women. Multivariate analysis showed that LVSI (p=0.0264) and deep myometrial invasion (p=0.0345) were independent predictive variables for the risk of distant haematogeneous failure. Patients with these pathological findings should be enrolled in randomised trials designed to assess the role of adjuvant chemotherapy alone or combined with sequential and/or concomitant external pelvic irradiation.

Monitoring of polychlorinated biphenyl contamination and estrogenic activity in water, commercial feed and farmed seafood.

We evaluated the concentration and congener distribution of seven "target" polychlorinated biphenyls (PCBs) present in water collected in different aquaculture farms of the Mediterranean area, commercial feeds, and farmed seafood. PCBs were present in feed and in tissues of all the analysed organisms at levels ranging from 1.96 ng g(-1) to 124.00 ng g(-1) wet weight, and in 10.5% of the water samples, at levels from under detection limit to 33.0 ng l(-1) with total PCB concentrations significantly higher in samples from the Tyrrhenian Sea than the Adriatic Sea. PCB congener distribution in tissues resembled that of feed, suggesting that commercial feed is an important source of PCBs. The estrogenicity of organic extracts of the samples was also evaluated by using an in vitro yeast reporter assay. Estrogenic activity higher than 10% of the activity induced by 10 nM 17 beta-estradiol was observed in 20.0% of seafood samples and 15.8% of water samples. Seafood and water samples from the Tyrrhenian Sea were more frequently estrogenic than the Adriatic ones (16.45 versus 4.08%). A significant correlation of total PCB concentrations on biological activity was observed for sea bass and mussels from the Adriatic Sea (p < 0.045 and p < 0.04, respectively), and for sea bass of the Tyrrhenian Sea (p = 0.05). These results indicate the need of an integral approach in the exposure assessment to potential toxic compounds for human via food.

Intratumoral microvessel density in advanced epithelial ovarian cancer and its use as a prognostic variable.

BACKGROUND: The aim of this retrospective study was to assess whether the intratumoral microvessel density (IMD) in primary tumour specimens had any impact on the clinical outcome of patients with advanced epithelial ovarian cancer treated in two Italian departments of gynaecological oncology. MATERIALS AND METHODS: The study was conducted on 101 patients who underwent initial surgery followed by platinum-based chemotherapy (37) or paclitaxel/platinum-based chemotherapy (64) for International Federation of Gynecology and Obstetrics (FIGO) stage III-IV epithelial ovarian cancer. The median follow-up of survivors from initial surgery was 65 months (range, 27 to 132 months). Paraffin-embedded sections of primary tumour specimens were analysed for IMD by immunohistochemistry using anti-CD34 antibodies. RESULTS: Progression-free survival and overall survival were significantly better in patients with IMD > or =40 microvessels/field compared with those with lower IMD (p = 0.0105 and p = 0.0065, respectively). Cox model showed that IMD was the strongest independent prognostic variable for both progression-free survival (p = 0.0267) and overall survival (p = 0.0189). CONCLUSION: An elevated IMD was associated with a significantly better progression-free survival and overall survival in patients with stage III-IV epithelial ovarian cancer who underwent initial surgery followed by chemotherapy, mainly consisting of a paclitaxel/platinum-based regimen.

Interleukin-8 is a powerful prognostic predictor of all-cause and cardiovascular mortality in dialytic patients.

BACKGROUND: Cohort studies have demonstrated an association between C-reactive protein (CRP) and interleukin-6 (IL-6) and all-cause and cardiovascular mortality in end-stage renal disease (ESRD) patients. Interleukin-8 (IL-8) appears to be not only the plasma expression of the acute-phase response but also a direct pathogenetic mediator of the atherosclerotic process. METHODS: To evaluate the role of IL-8 in predicting outcome, 76 chronic dialytic patients were prospectively followed for 18 months. At baseline, blood samples were taken for analysis of high-sensitivity CRP, IL-6, IL-8 and other standard laboratory analyses. RESULTS: Median IL-8 was 5.2 mg/l, therefore near half of the patients had IL-8 values within the range of 'normal limits'. IL-6 and CRP were significantly correlated (r = 0.45, p < 0.001) and a positive correlation was also found between IL-6 and IL-8 (r = 0.39, p < 0.001). The correlation coefficient between IL-6 and CRP was 0.43 (p < 0.001) and 0.50 (p < 0.001) in patients without and with history and/or clinical signs of cardiovascular disease, respectively. After a follow-up of 1.5 years, 8 patients had died from cardiovascular causes and another 7 patients for other reasons; furthermore 9 major nonfatal cardiovascular events were recorded. Stepwise regression analysis showed IL-8 as the strongest independent predictor of all-cause and cardiovascular events (p = 0.0025) even after adjustment for age and dialytic age, followed by IL-6 and CRP (p < 0.01). CONCLUSION: Despite a small population and a relatively short follow-up period, this study firstly demonstrated that IL-8 is a powerful independent predictive factor for cardiovascular and overall mortality cause in ESRD patients.

Assessment of swallowing by oropharyngoesophageal scintigraphy in patients with amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is the most common degenerative motor neuron disease in adults, and dysphagia is one of its most frequent and disabling symptoms. Oropharyngoesophageal scintigraphy (OPES) permits a functional and semiquantitative study of the various stages of swallowing. We studied 28 ALS patients (12 females and 16 males; mean age = 63.57 +/- 10.39 yr SD), who were clinically rated against the ALSFRS scale (Amyotrophic Lateral Sclerosis Functioning Rating Scale) and underwent OPES with (99m)Tc-nanocolloid using either a liquid or a semisolid bolus. The semiquantitative parameters we analyzed were Oral Transit Time (OTT), Pharyngeal Transit Time (PTT), Esophageal Transit Time (ETT), Retention Index (RI), and Esophageal Emptying Rate (EER(10s)). Hence, the OPES performed with a semisolid bolus produced a higher proportion of pathologic values for the swallowing variables than when liquid bolus was used. Analyzed by grouping the patients into classes according to their bulbar ALSFRS scores, we found a significant increase in the OTT (p < 0.005), PTT (p < 0.02), and Oropharyngeal Retention Index (OPRI) (p < 0.0004) variables in ALS patients with more severe bulbar involvement. OPES has turned out to be a very important examination for detecting tracheal-bronchial inhalation and it also offers the possibility of acquiring a semiquantitative evaluation of the amount of food inhaled. In our experience, OPES in patients with ALS has been easy to use, economic, well tolerated, and capable of supplying precise indications with regard to the extent of the swallowing disorder, which permits a better clinical definition of the ALS patient.

Relationship between time interval from primary surgery to the start of taxane- plus platinum-based chemotherapy and clinical outcome of patients with advanced epithelial ovarian cancer: results of a multicenter retrospective Italian study.

PURPOSE: To assess whether the interval from primary surgery to the start of taxane- plus platinum-based chemotherapy has any impact on the clinical outcome of advanced ovarian cancer patients. PATIENTS AND METHODS: The study was conducted on 313 patients who underwent surgery followed by taxane- plus platinum-based chemotherapy. The median follow-up of survivors was 30.7 months (range, 6 to 109 months). RESULTS: The 25%, 50%, and 75% quantiles of intervals from surgery to the start of chemotherapy were 11, 21, and 31 days, respectively. After the sixth cycle, 102 patients achieved a pathologic complete response at second-look surgery and 98 obtained a clinical complete response but were not submitted to second-look surgery. Taking into consideration the best assessed response, a complete (either clinical or pathologic) response was found in 200 patients. Residual disease (< or = 1 v > 1 cm; P < .0001) and ascites (absent v present; P = .003) were independent predictive factors for achieving a complete response, whereas residual disease (P = .001) and stage (IIc to III v IV; P = .04) were independent prognostic variables for survival. Conversely, statistical analyses failed to detect significant differences in complete response rates and survival among patients with an interval from surgery to chemotherapy shorter than 11 days, 12 to 21 days, 22 to 31 days, and longer than 31 days. CONCLUSION: The interval from surgery to the start of taxane- plus platinum-based chemotherapy seems to have neither a predictive value for response to treatment nor a prognostic relevance for survival of advanced ovarian cancer patients.

Clinical feasibility of two-step streptavidin/111In-biotin scintigraphy in patients with suspected vertebral osteomyelitis.

PURPOSE: Streptavidin accumulates at sites of inflammation and infection as a result of increased capillary permeability. In addition to being utilised by bacteria for their own growth, biotin forms a stable, high-affinity non-covalent complex with avidin. The objective of this investigation was to determine the diagnostic performance of two-step streptavidin/111In-biotin imaging for evaluating patients with suspected vertebral osteomyelitis. METHODS: We evaluated 55 consecutive patients with suspected vertebral osteomyelitis (34 women and 21 men aged 27-86 years), within 2 weeks after the onset of clinical symptoms. Thirty-two of the patients underwent magnetic resonance imaging (MRI) and 24, computed tomography (CT). DTPA-conjugated biotin was radiolabelled by incubating 500 microg of DTPA-biotin with 111 MBq of 111In-chloride. Two-step scintigraphy was performed by first infusing 3 mg streptavidin intravenously, followed 4 h later by 111In-biotin. Imaging was begun 60 min later. RESULTS: Streptavidin/111In-biotin scintigraphy was positive in 32/34 patients with spinal infection (94.12% sensitivity). The study was negative in 19/21 patients without infection (95.24% specificity). The corresponding results for MRI and CT were 54.17% and 35.29% (sensitivity), and 75% and 57.14% (specificity), respectively. All statistical parameters of diagnostic performance (Youden's J index, kappa measure of agreement with correct classification, accuracy, sensitivity, specificity, positive likelihood and negative likelihood) were clearly better for streptavidin/111In-biotin scintigraphy than for either MRI or CT. CONCLUSION: Streptavidin/111In-biotin scintigraphy is highly sensitive and specific for detecting vertebral osteomyelitis in the first 2 weeks after the onset of clinical symptoms, and is potentially very useful for guiding clinical decisions on instituting appropriate therapy.

The predictive and prognostic value of serum CA 125 half-life during paclitaxel/platinum-based chemotherapy in patients with advanced ovarian carcinoma.

OBJECTIVES: Serum CA 125 kinetics during early chemotherapy has a strong predictive and prognostic relevance for patients with advanced ovarian carcinoma who received a first-line platinum-based regimen, whereas the ability of serum CA 125 assay to reflect the response to paclitaxel-based chemotherapy has not yet been defined. The aim of the present paper is to calculate the serum CA 125 half-life during first-line paclitaxel/platinum-based chemotherapy in patients with advanced ovarian carcinoma and to correlate this kinetic parameter with the response to treatment, progression-free survival and overall survival. METHODS: This retrospective investigation assessed 71 patients with stages IIc-IV ovarian carcinoma who underwent initial surgery followed by paclitaxel/platinum-based chemotherapy and who had serum CA 125 > 35 U/ml before the first cycle of chemotherapy. Only epithelial ovarian cancers were included. RESULTS: The 25%, 50%, and 75% quantiles of serum CA 125 half-life during early chemotherapy were 10, 14, and 20 days, respectively. Taking the value corresponding to the 50% quantile (i.e., 14 days) as cutoff limit, serum CA 125 half-life was an independent prognostic factor for the chance of achieving a complete response to treatment as well as for progression-free survival and overall survival. In detail, patients with serum antigen half-life <== 14 days had a 3.362 times as great probability to achieve a complete response and a 3.113 times as low probability to die when compared to those with a longer half-life. CONCLUSIONS: Serum CA 125 assay represents a reliable biochemical tool for the management of advanced ovarian carcinoma patients who receive a first-line paclitaxel/platinum-based chemotherapy.

Relevance of plasma D-dimer measurement in patients with acute peripheral vertigo.

The aetiopathogenesis of acute unilateral peripheral vestibular dysfunction (APV), also known as vestibular neuritis, is still debated: the principal cause is viral infection with vascular factors second in importance. Plasmatic D-dimer, considered a plasmatic index of hypercoagulation, was measured in a group of 45 APV patients and in a group of 25 patients suffering from Ménière's disease. Measurements were taken both during the acute stage and after a four to six week period of pharmacological washout. The mean D-dimer levels were significantly higher than those measured in the controls both during the acute phase (301 SD161 vs 202 SD113 ng/mL) and after follow up (304 SD211 vs 192 SD111 ng/mL) (p = 0.008). Moreover, during the acute stage 23 of the APV patients (51.1 per cent) had plasmatic D-dimer levels above the upper normal limit (i.e.: <300 ng/mL), compared to four of those with Ménière's disease (16 per cent). Our results lead us to postulate an involvement of the haemostatic system in APV.

Intratumoral microvessel density, response to chemotherapy and clinical outcome of patients with advanced ovarian carcinoma.

BACKGROUND: The aim of this study was to assess intratumoral microvessel density (IMD) in tissue samples from primary ovarian carcinomas, and to correlate this angiogenic parameter with the common clinico-pathological variables, response to chemotherapy and prognosis of patients with this malignancy. PATIENTS AND METHODS: The investigation was conducted on 64 patients who underwent initial surgery for FIGO stages I-IV ovarian carcinoma. Paraffin-embedded sections of primary tumor specimens were analyzed for IMD by immunohistochemistry using anti-CD34 antibodies. In detail, we assessed the 49 patients with advanced (FIGO stages II-IV) disease. Postoperative chemotherapy consisted of paclitaxel/platinum-based chemotherapy in 36 (73.5%) patients and platinum-based chemotherapy in 13. RESULTS: The IMD ranged from 6 to 115 microvessels/field, with a median value of 40, and correlated with none of the common clinico-pathological variables of ovarian carcinoma. As for the patients with advanced disease, women with elevated IMD (> or = 40 microvessels/field) had a higher chance of achieving a complete response to chemotherapy when compared to those with lower IMD (p = 0.0068). Multiple logistic regression showed that IMD was an independent predictor of complete response to chemotherapy (p = 0.0094). By log-rank test, patients with elevated IMD had a better progression-free survival (p = 0.0039) and a better overall survival (p = 0.0365) when compared to those with lower IMD. The Cox model showed that IMD was the only independent prognostic variable for both progression-free survival (p = 0.0112) and overall survival (p = 0.0296). DISCUSSION: The present retrospective analysis seems to show a positive association between IMD, response to chemotherapy, mainly represented by a paclitaxel/platinum-based regimen, and clinical outcome of patients with advanced ovarian carcinoma.

C-reactive protein and interleukin-6 levels are related to renal function in predialytic chronic renal failure.

BACKGROUND: Several studies have provided convincing evidence that in apparently healthy subjects elevated serum levels of plasma C-reactive protein (CRP) are associated with an increased risk of experiencing myocardial infarction and sudden cardiac death. It has been claimed that, in dialytic patients, the hepatic synthesis of this 'acute phase response' plasma protein is primarily induced by the macrophage-derived interleukin 6 (IL-6). Little information is available, however, regarding CRP and IL-6 plasma levels in pre-dialytic renal failure. METHODS: Plasma CRP by a modification of the laser nephelometry technique, IL-6 and serum albumin were determined in 103 chronic pre-dialytic patients (mean age 50 +/- 6.3 years; creatinine clearance (Cr.cl.) 36.3 +/- 23.1 ml/min). RESULTS: CRP was >5 mg/l (normal upper range) in 42% of the global population. CRP and IL-6 were significantly related (r = 0.35, p < 0.0004). CRP and IL-6 were related to renal function (CRP vs. Cr.cl., r = -0.56, p < 0.0001; IL-6 vs. Cr.cl., r = -0.55, p < 0.0001, Spearman correlation coefficient). When patients were divided in tertiles according to renal function, CRP median value resulted 7.9 mg/l (interquartile interval: 5-12) in the first tertile (Cr.cl. <18.5 ml/min), 4.0 mg/l (3-6) in the second tertile (Cr.cl. 18.5-45 ml/min) and 3.2 mg/l (2.7-4.0) in the last tertile (Cr.cl. >45 ml/min) (p < 0.0001). A negative correlation between CRP and S-albumin was also found (r = -0.52, p < 0.0001, Spearman correlation coefficient). CONCLUSIONS: IL-6 and CRP were increased and were inversely related to creatinine clearance in our population of 103 chronic predialytic patients. The possibility of a decreased renal clearance of CRP and/or cytokines as a cause of an activated acute-phase response is discussed. A negative correlation between CRP and S-albumin was found confirming the link between chronic inflammation and malnutrition in chronic renal patients.
