Case report of Usutu virus infection in an immunocompromised patient in Italy, 2022.

Usutu virus (USUV) is an arthropod-borne flavivirus emerged in Africa in 1950s and in Eruope in 1990s causing a massive number of birds' deaths. The role of USUV as human pathogen has been only recently hypothesized and cases of USUV infection in humans remain limited and often related to immunocompromised subjects. Herein, we report a case of USUV meningoencephalitis infection in an immunocompromised patient with no history of previous flavivirus infection. The infection due to USUV evolved rapidly since hospital admission thus resulting fatal in few days after symptoms onset and, although not proven, a suspected bacteria co-infection has been hypothesized. Based on these findings, we suggested that when USUV meningoencephalitis is suspected in countries endemic, careful attention should be applied to neurological syndromes during summer months especially among immunocompromised patients.

Functional Characterization of p.(Arg160Gln) PCSK9 Variant Accidentally Found in a Hypercholesterolemic Subject.

Familial hypercholesterolaemia (FH) is an autosomal dominant dyslipidaemia, characterised by elevated LDL cholesterol (LDL-C) levels in the blood. Three main genes are involved in FH diagnosis: LDL receptor (LDLr), Apolipoprotein B (APOB) and Protein convertase subtilisin/kexin type 9 (PCSK9) with genetic mutations that led to reduced plasma LDL-C clearance. To date, several PCSK9 gain-of-function (GOF) variants causing FH have been described based on their increased ability to degrade LDLr. On the other hand, mutations that reduce the activity of PCSK9 on LDLr degradation have been described as loss-of-function (LOF) variants. It is therefore important to functionally characterise PCSK9 variants in order to support the genetic diagnosis of FH. The aim of this work is to functionally characterise the p.(Arg160Gln) PCSK9 variant found in a subject suspected to have FH. Different techniques have been combined to determine efficiency of the autocatalytic cleavage, protein expression, effect of the variant on LDLr activity and affinity of the PCSK9 variant for the LDLr. Expression and processing of the p.(Arg160Gln) variant had a result similar to that of WT PCSK9. The effect of p.(Arg160Gln) PCSK9 on LDLr activity is lower than WT PCSK9, with higher values of LDL internalisation (13%) and p.(Arg160Gln) PCSK9 affinity for the LDLr is lower than WT, EC50 8.6 ± 0.8 and 25.9 ± 0.7, respectively. The p.(Arg160Gln) PCSK9 variant is a LOF PCSK9 whose loss of activity is caused by a displacement of the PCSK9 P' helix, which reduces the stability of the LDLr-PCSK9 complex.

[Identifying possible homozygous familial hypercholesterolemia patients: an Italian experts' opinion]. / Inquadramento diagnostico del paziente con possibile ipercolesterolemia familiare omozigote: il parere di un gruppo italiano di esperti.

Homozygous familial hypercholesterolemia (HoFH) is a rare genetic disease characterized by high plasma levels of low-density lipoprotein cholesterol (LDL-C) and massive risk of premature atheromasia and cardiovascular events. HoFH is caused by mutations in several genes, such as LDLR, APOB, PCSK9 and LDLRAP1. If untreated, the average age of death is 18 years old, but fatalities within the first 5 years of age have been recorded. Therefore, early diagnosis and treatment are crucial, in order to prevent and/or delay the cardiovascular complications of LDL-C exposure. Because HoFH is a rare disorder, it is not frequently encountered in daily clinical practice at the primary/secondary unspecialized cardiological centers. Then the availability of practical indications helping to identify HoFH patients or to arise a suspect of HoFH is particularly strategic to promptly start the appropriate lipid-lowering therapy. For such a purpose, a group of Italian experts suggests three useful algorithms to identify cases requiring accurate and specialized clinical evaluation as potential HoFH patients. These cases with suspected HoFH should be addressed to specialized centres for the optimal management of these patients.

Intravenous methylprednisolone pulses in hospitalised patients with severe COVID-19 pneumonia: a double-blind, randomised, placebo-controlled trial.

RATIONALE: Pulse glucocorticoid therapy is used in hyperinflammation related to coronavirus disease 2019 (COVID-19). We evaluated the efficacy and safety of pulse intravenous methylprednisolone in addition to standard treatment in COVID-19 pneumonia. METHODS: In this multicentre, randomised, double-blind, placebo-controlled trial, 304 hospitalised patients with COVID-19 pneumonia were randomised to receive 1 g of methylprednisolone intravenously for three consecutive days or placebo in addition to standard dexamethasone. The primary outcome was the duration of patient hospitalisation, calculated as the time interval between randomisation and hospital discharge without the need for supplementary oxygen. The key secondary outcomes were survival free from invasive ventilation with orotracheal intubation and overall survival. RESULTS: Overall, 112 (75.4%) out of 151 patients in the pulse methylprednisolone arm and 111 (75.2%) of 150 in the placebo arm were discharged from hospital without oxygen within 30 days from randomisation. Median time to discharge was similar in both groups (15 days, 95% CI 13.0-17.0 days and 16 days, 95% CI 13.8-18.2 days, respectively; hazard ratio (HR) 0.92, 95% CI 0.71-1.20; p=0.528). No significant differences between pulse methylprednisolone and placebo arms were observed in terms of admission to intensive care unit with orotracheal intubation or death (20.0% versus 16.1%; HR 1.26, 95% CI 0.74-2.16; p=0.176) or overall mortality (10.0% versus 12.2%; HR 0.83, 95% CI 0.42-1.64; p=0.584). Serious adverse events occurred with similar frequency in the two groups. CONCLUSIONS: Methylprenisolone pulse therapy added to dexamethasone was not of benefit in patients with COVID-19 pneumonia.

Search for familial hypercholesterolemia patients in an Italian community: A real-life retrospective study.

BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common inherited disorder of low-density lipoprotein (LDL) catabolism that causes elevated LDL-cholesterol (LDL-C) and premature atherosclerotic cardiovascular disease (ASCVD). Despite the availability of effective treatments, FH remains underdiagnosed and undertreated. The aims of the study were to identify putative FH subjects using data from laboratory and cardiology databases, genetically characterize suspected FH patients referred to the Lipid Clinic and monitor attainment of treatment goals in identified patients. METHODS AND RESULTS: We retrieved the electronic health records of 221,644 individuals referred to laboratory for routine assessment and of 583 ASCVD patients (age ≤65) who underwent percutaneous transluminal coronary angioplasty (PTCA). We monitored the lipid profiles of subjects with LDL-C ≥ 250 mg/dl identified by laboratory survey (LS-P), PTCA patients and patients from the Lipid Clinic (LC-P). The laboratory survey identified 1.46% of subjects with LDL-C ≥ 190 mg/dl and 0.08% with LDL-C ≥ 250 mg/dl. Probable/definite FH was suspected in 3% of PTCA patients. Molecularly-confirmed FH was found in 44% of LC-P subjects. Five new LDLR mutations were identified. The 50% LDL-C reduction target was achieved by 70.6% of LC-P patients. Only 18.5% of PTCA patients reached the LDL-C < 55 mg/dl target. CONCLUSION: By using a combined approach based on laboratory lipid profiles, documented ASCVD and Lipid Clinic data, we were able to identify subjects with a high probability of being FH. Attainment of LDL-C goals was largely suboptimal. Efforts are needed to improve FH detection and achievement of lipid targets.

Predictive factors of clinical outcomes in patients with COVID-19 treated with tocilizumab: A monocentric retrospective analysis.

OBJECTIVE: The aim of this retrospective observational study is to analyse clinical, serological and radiological predictors of outcome in patients with COVID-19 pneumonia treated with tocilizumab, providing clinical guidance to its use in real-life. METHOD: This is a retrospective, monocentric observational cohort study. All consecutive patients hospitalized between February the 11th and April 14th 2020 for severe COVID-19 pneumonia at Reggio Emilia AUSL and treated with tocilizumab were enrolled. The patient's clinical status was recorded every day using the WHO ordinal scale for clinical improvement. Response to treatment was defined as an improvement of one point (from the status at the beginning of tocilizumab treatment) during the follow-up on this scale. Bivariate association of main patients' characteristics with outcomes was explored by descriptive statistics and Fisher or Kruskal Wallis tests (respectively for qualitative or quantitative variables). Each clinically significant predictor was checked by a loglikelihood ratio test (in univariate logistic models for each of the considered outcomes) against the null model. RESULTS: A total of 173 patients were included. Only hypertension, the use of angiotensin-converting enzyme inhibitors, PaO2/FiO2, respiratory rate and C-reactive protein were selected for the multivariate analysis. In the multivariable model, none of them was significantly associated with response. CONCLUSIONS: Evaluating a large number of clinical variables, our study did not find new predictors of outcome in COVID19 patients treated with tocilizumab. Further studies are needed to investigate the use of tocilizumab in COVID-19 and to better identify clinical phenotypes which could benefit from this treatment.

Case Report: Irreversible Watery Diarrhea, Severe Metabolic Acidosis, Hypokalemia and Achloridria Syndrome Related to Vasoactive Intestinal Peptide Secreting Malignant Pheochromocytoma.

Background: Pheochromocytoma (PHEO) clinical manifestations generally mirror excessive catecholamines secretion; rarely the clinical picture may reflect secretion of other hormones. Watery diarrhea, hypokalemia and achlorhydria (WDHA) is a rare syndrome related to excessive secretion of vasoactive intestinal peptide (VIP). Clinical Case: A 73-year-old hypotensive man affected by adrenal PHEO presented with weight loss and watery diarrhea associated with hypokalemia, hyperchloremic metabolic acidosis (anion gap 15 mmol/l) and a negative urinary anion gap. Abdominal computed tomography scan showed a right adrenal PHEO, 8.1 cm in maximum diameter, with tracer uptake on 68GaDOTA-octreotate positron emission tomography. Metastasis in lumbar region and lung were present. Both chromogranin A and VIP levels were high (more than10 times the normal value) with slightly elevated urine normetanephrine and metanephrine excretion. Right adrenalectomy was performed and a somatostatin analogue therapy with lanreotide started. Immunostaining showed chromogranin A and VIP co-expression, with weak somatostatin-receptor-2A positivity. In two months, patient clinical conditions deteriorated with severe WDHA and multiple liver and lung metastasis. Metabolic acidosis and hypokalemia worsened, leading to hemodynamic shock and exitus. Conclusions: A rare case of WDHA syndrome caused by malignant VIP-secreting PHEO was diagnosed. High levels of circulating VIP were responsible of the rapidly evolving clinical picture with massive dehydration and weight loss along with severe hyperchloremic metabolic acidosis and hypokalemia due to the profuse untreatable diarrhea. The rescue treatment with lanreotide was unsuccessful because of the paucity of somatostatin-receptor-2A on VIP-secreting PHEO chromaffin cells.

Acute-phase reactants during tocilizumab therapy for severe COVID-19 pneumonia.

OBJECTIVES: To identify predictors of clinical improvement and intubation/death in tocilizumab-treated severe COVID19, focusing on IL6 and CRP longitudinal monitoring. METHODS: 173 consecutive patients with severe COVID-19 pneumonia receiving tocilizumab in Reggio Emilia province Hospitals between 11 March and 3 June 2020 were enrolled in a prospective cohort study. Clinical improvement was defined as status improvement on a six-category ordinal scale or discharge from the hospital, whichever came first. A composite outcome of intubation/death was also evaluated. CRP and IL-6 levels were determined before TCZ administration (T0) and after 3 (T3), and 7 (T7) days. RESULTS: At multivariate analysis T0 and T3 CRP levels were negatively associated with clinical improvement (OR 0.13, CI 0.03-0.55 and OR 0.11, CI 0.0-0.46) (p=0.006 and p=0.003) and positively associated with intubation/death (OR 17.66, CI 2.47-126.14 and OR 5.34, CI: 1.49-19.12) (p=0.01 and p=0.004). No significant associations with IL-6 values were observed. General linear model analyses for repeated measures showed significantly different trends for CRP from day 3 to day 7 between patients who improved and those who did not, and between patients who were intubated or died and those who were not (p<0.0001 for both). ROC analysis identified a baseline CRP level of 15.8 mg/dl as the best cut-off to predict intubation/death (AUC = 0.711, sensitivity = 0.67, specificity = 0.71). CONCLUSIONS: CRP serial measurements in the first week of TCZ therapy are useful in identifying patients developing poor outcomes.

TOCIVID-19 - A multicenter study on the efficacy and tolerability of tocilizumab in the treatment of patients with COVID-19 pneumonia. Study protocol.

BACKGROUND: Pneumonia is the most frequent complication of COVID-19, due to an aberrant host immune response that is associated with an acute respiratory distress syndrome, and, in most critical patients, with a "cytokine storm". IL-6 might play a key role in the cytokine storm and might be a potential target to treat severe and critical COVID-19. Tocilizumab is a recombinant humanized monoclonal antibody, directed against IL-6 receptor. METHODS: This multicentre study project includes a single-arm phase 2 study and a further parallel cohort, enrolling hospitalized patients with COVID-19 pneumonia and oxygen saturation at rest in ambient air ≤93% or requiring respiratory support. Patients receive tocilizumab 8 mg/kg (up to 800 mg) as one intravenous administration. A second administration (same dose) after 12 h is optional. Two-week and one-month lethality rates are the co-primary endpoints. Sample size planned for the phase 2 study is 330 patients. The parallel cohort will include patients who cannot enter the phase 2 study because being intubated from more than 24 h, or having already received tocilizumab, or the phase 2 study has reached sample size. Primary analysis will include patients enrolled in the phase 2 study. Results of the primary analysis will be validated in the prospective cohort of patients consecutively registered after phase 2 closure from March 20 to March 24, who were potentially eligible for the phase 2 study. CONCLUSION: This trial aims to verify the safety and efficacy of tocilizumab in the Italian population with COVID-19 pneumonia and respiratory impairment. EudraCT Number: 2020-001110-38; Clinicaltrials.gov ID NCT04317092.

Tocilizumab for patients with COVID-19 pneumonia. The single-arm TOCIVID-19 prospective trial.

BACKGROUND: Tocilizumab blocks pro-inflammatory activity of interleukin-6 (IL-6), involved in pathogenesis of pneumonia the most frequent cause of death in COVID-19 patients. METHODS: A multicenter, single-arm, hypothesis-driven trial was planned, according to a phase 2 design, to study the effect of tocilizumab on lethality rates at 14 and 30 days (co-primary endpoints, a priori expected rates being 20 and 35%, respectively). A further prospective cohort of patients, consecutively enrolled after the first cohort was accomplished, was used as a secondary validation dataset. The two cohorts were evaluated jointly in an exploratory multivariable logistic regression model to assess prognostic variables on survival. RESULTS: In the primary intention-to-treat (ITT) phase 2 population, 180/301 (59.8%) subjects received tocilizumab, and 67 deaths were observed overall. Lethality rates were equal to 18.4% (97.5% CI: 13.6-24.0, P = 0.52) and 22.4% (97.5% CI: 17.2-28.3, P < 0.001) at 14 and 30 days, respectively. Lethality rates were lower in the validation dataset, that included 920 patients. No signal of specific drug toxicity was reported. In the exploratory multivariable logistic regression analysis, older age and lower PaO2/FiO2 ratio negatively affected survival, while the concurrent use of steroids was associated with greater survival. A statistically significant interaction was found between tocilizumab and respiratory support, suggesting that tocilizumab might be more effective in patients not requiring mechanical respiratory support at baseline. CONCLUSIONS: Tocilizumab reduced lethality rate at 30 days compared with null hypothesis, without significant toxicity. Possibly, this effect could be limited to patients not requiring mechanical respiratory support at baseline. Registration EudraCT (2020-001110-38); clinicaltrials.gov (NCT04317092).

Feasibility and clinical impact of out-of-ICU noninvasive respiratory support in patients with COVID-19-related pneumonia.

INTRODUCTION: The severe acute respiratory syndrome-coronavirus 2 outbreak spread rapidly in Italy and the lack of intensive care unit (ICU) beds soon became evident, forcing the application of noninvasive respiratory support (NRS) outside the ICU, raising concerns over staff contamination. We aimed to analyse the safety of the hospital staff and the feasibility and outcomes of NRS applied to patients outside the ICU. METHODS: In this observational study, data from 670 consecutive patients with confirmed coronavirus disease 2019 referred to pulmonology units in nine hospitals between March 1 and May 10, 2020 were analysed. Data collected included medication, mode and usage of NRS (i.e. high-flow nasal cannula (HFNC), continuous positive airway pressure (CPAP), noninvasive ventilation (NIV)), length of stay in hospital, endotracheal intubation (ETI) and deaths. RESULTS: 42 (11.1%) healthcare workers tested positive for infection, but only three of them required hospitalisation. Data are reported for all patients (69.3% male), whose mean±sd age was 68±13 years. The arterial oxygen tension/inspiratory oxygen fraction ratio at baseline was 152±79, and the majority (49.3%) of patients were treated with CPAP. The overall unadjusted 30-day mortality rate was 26.9%, with 16%, 30% and 30% for HFNC, CPAP and NIV, respectively, while the total ETI rate was 27%, with 29%, 25% and 28%, respectively; the relative probability of death was not related to the NRS used after adjustment for confounders. ETI and length of stay were not different among the groups. Mortality rate increased with age and comorbidity class progression. CONCLUSIONS: The application of NRS outside the ICU is feasible and associated with favourable outcomes. Nonetheless, it was associated with a risk of staff contamination.

Multicenter, randomised, open-label, non-comparative phase 2 trial on the efficacy and safety of the combination of bevacizumab and trabectedin with or without carboplatin in women with partially platinum-sensitive recurrent ovarian cancer.

BACKGROUND: Trabectedin, in addition to its antiproliferative effect, can modify the tumour microenvironment and this could be synergistic with bevacizumab. The efficacy and safety of trabectedin and bevacizumab ± carboplatin have never been investigated. METHODS: In this phase 2 study, women progressing between 6 and 12 months since their last platinum-based therapy were randomised to Arm BT: bevacizumab, trabectedin every 21 days, or Arm BT+C: bevacizumab, trabectedin and carboplatin every 28 days, from cycles 1 to 6, then trabectedin and bevacizumab as in Arm BT. Primary endpoints were progression-free survival rate (PFS-6) and severe toxicity rate (ST-6) at 6 months, assuming a PFS-6 ≤35% for BT and ≤40% for BT+C as not of therapeutic interest and, for both arms, a ST-6 ≥ 30% as unacceptable. RESULTS: BT+C (21 patients) did not meet the safety criteria for the second stage (ST-6 45%; 95%CI: 23%-69%) but PFS-6 was 85% (95%CI: 62%-97%). BT (50 patients) had 75% PFS-6 (95%CI: 60%-87%) and 16% ST-6 (95%CI 7%-30%). CONCLUSIONS: BT compared favourably with other platinum- and non-platinum-based regimens. The combination with carboplatin needs to be assessed further in a re-modulated safer schedule to confirm its apparent strong activity. CLINICAL TRIAL REGISTRATION: NCT01735071 (Clinicaltrials.gov).

A phase II randomised (calibrated design) study on the activity of the single-agent trabectedin in metastatic or locally relapsed uterine leiomyosarcoma.

BACKGROUND: Patients with recurrent/metastatic uterine leiomyosarcoma (U-LMS) have a dismal prognosis. This phase II study aims to evaluate trabectedin efficacy and safety in advanced U-LMS. METHODS: Eligible patients had received ≥ one line of chemotherapy. Gemcitabine ± docetaxel naive patients were randomised to Arm A: trabectedin 1.3 mg/m2 or calibration Arm B: gemcitabine 900 mg/m2 and docetaxel 75 mg/m2. Patients who had already received gemcitabine ± docetaxel directly entered Arm A. Primary end-point: 6-month progression-free rate (PFS-6). The null hypothesis that the true PFS-6 = 14% was tested against a one-sided alternative. This design yielded a 5% type I error rate and 90% power when the true PFS-6 is 25%. RESULTS: Overall, 126 patients entered Arm A (45 from randomisation and 81 directly) and 42 Arm B. Arm A patients characteristics: median age = 57; ≥2 previous chemotherapy lines = 37.4%; metastatic disease = 93%. The study met the condition for trabectedin activity: PFS-6 = 35.2% (95% CI: 26.2-45). No difference in PFS by the number of previous chemotherapy lines emerged. Median OS = 20.6 months (IQR: 8-36.4). In Arm B, the PFS-6 = 51.5% (95% CI: 33.5-69.2). No toxic deaths occurred. In Arm A, only 4 patients interrupted treatment for toxicity. CONCLUSIONS: Trabectedin is active and well tolerated, retaining similar efficacy across one to three previous lines of chemotherapy.

Plasma Exchange for the Treatment of Transient Extreme Hypertriglyceridemia Associated with Diabetic Ketoacidosis and Acute Pancreatitis.

Diabetic ketoacidosis (DKA) can quite frequently present in association with acute pancreatitis (AP) caused by transient severe hypertriglyceridemia (HTG). Here we report the case of a patient presenting with DKA, severe HTG and AP who received urgent plasma exchange for HTG control, and who reached adequate serum triglyceride levels only after appropriate DKA management. The treatment of patients presenting with DKA and coexistent AP associated with severe HTG should focus first on appropriate DKA management. Plasma exchange as a treatment for severe HTG in patients with DKA and AP should be evaluated carefully. LEARNING POINTS: The treatment of patients presenting with diabetic ketoacidosis, acute pancreatitis and severe hypertriglyceridemia should focus first on diabetic ketoacidosis management.Plasma exchange as a treatment for severe hypertriglyceridemia in patients with diabetic ketoacidosis and acute pancreatitis should be evaluated carefully.Triglyceride concentrations should always be measured in case of diabetic ketoacidosis.

Severe Milk-Alkali Syndrome in a Patient with Hypoparathyroidism Associated with 1,25(OH)2D, Hydrochlorothiazide and Anthranoid Laxative Consumption.

BACKGROUND: Milk-alkali syndrome is a life-threatening condition defined by the triad of hypercalcaemia, metabolic alkalosis and acute renal failure, and is associated with consumption of calcium and absorbable alkali. METHODS: We report the case of a patient admitted to a step-down unit of a large hospital in Italy. RESULTS: The patient was a 59-year-old woman with hypoparathyroidism and mild chronic kidney insufficiency, treated for a preceding episode of hypocalcaemia with high doses of calcitriol and calcium carbonate, who was also taking hydrochlorothiazide and unreported herbal anthranoid laxatives. The patient was admitted to hospital with severe hypercalcaemia, severe metabolic alkalosis and acute renal insufficiency. The patient was successfully treated with urgent dialysis, loop diuretics and calcitonin administration. CONCLUSIONS: This case underlines the need for caution when treating patients with impaired calcium metabolism regulation, and suggests that herbal anthranoid laxatives might act as triggers for milk-alkali syndrome. LEARNING POINTS: Patients with hypoparathyroidism are more prone to develop milk-alkali syndrome.Patients need careful follow-up and review of their need for calcium supplements.Non-prescription and complementary medicines can aggravate hypercalcaemia.

Effects of transdermal buprenorphine on patients-reported outcomes in cancer patients: results from the Cancer Pain Outcome Research (CPOR) Study Group.

OBJECTIVES: Pain still afflicts most cancer patients, mainly in the metastatic phases, and under-treatment is well documented. Transdermal delivery systems (TDS) containing fentanyl or buprenorphine could potentiality have advantages over oral and parenteral routes, but evidence from comparative trials are scanty. In the framework of a wider initiative, an Outcome Research Study was carried out in Italy in 2006 to evaluate the effects of various analgesic options, particularly buprenorphine TDS. METHODS: This is a multicenter, open-label, prospective, nonrandomized study. Data were collected using a web-based standardized system, with a follow-up up of to 3 months. Pain intensity, the primary outcomes of the study, was measured using 11-point numerical rating scales from the Brief Pain Inventory. RESULTS: One-hundred ten centers recruited 1801 cases, most of which (60%) were receiving a strong opioid at the time of inclusion. Of these, 257 had TDS buprenorphine as first choice. Of the remaining 709 patients who at the time of inclusion were not on a strong opioid, 325 changed to a strong opioid and in 43% it was TDS buprenorphine. During the follow-up, physicians had to increase the dosage to control pain (average increase between 16% and 17%). About 34% of patients had an improvement of at least 2 points in worst pain, 15% had a 20% improvement in pain relief, and 40% in satisfaction. Results were in line with those of patients receiving other World Health Organization-level III opioids. CONCLUSIONS: Despite the limitations owing to the observational design, these findings may be useful to clinicians to judge the value of the drug under evaluation better and to help researchers design further comparative studies.

A double-blind, placebo-controlled, randomized trial of bupropion for smoking cessation in primary care.

BACKGROUND: Studies undertaken in academic settings have shown that bupropion hydrochloride can double the odds of smoking cessation compared with placebo. To assess whether these results are applicable in primary care, we launched a double-blind, placebo-controlled, randomized trial to be conducted by general practitioners. METHODS: We assigned 593 healthy smokers to receive bupropion hydrochloride, 150 mg twice a day, or placebo daily for 7 weeks (hereinafter, bupropion group [n = 400] and placebo group [n = 193], respectively). After the baseline visit, 4 clinical visits and 3 telephone calls were scheduled over the 1-year period. The primary end points were biochemically confirmed continuous abstinence at week 7 and at week 52. RESULTS: Seventy-one Italian general practitioners enrolled participants from April 2004 to May 2005. Of the bupropion group, 41.0% were continuously abstinent from week 4 to week 7 compared with 22.3% of the placebo group (multivariate odds ratio, 2.37; 95% confidence interval, 1.60-3.53). The continuous abstinence rates from week 4 to week 52 were 25% in the bupropion group and 14% in the placebo group (odds ratio, 2.11; 95% confidence interval, 1.32-3.39). The mean weight gain was similar in both groups and among long-term abstainers was 3 kg in women and 4 kg in men. More participants in the bupropion group experienced an adverse event than those in the placebo group, but the percentage who discontinued use of the study medication was similar. CONCLUSIONS: Bupropion more than doubled the odds of continuous abstinence from smoking. The adherence of general practitioners and participants to the protocol was excellent, making our findings robust and easy to generalize to the context of primary care.

A multidisciplinary project to improve the quality of cancer pain management in Italy: background, methods, and preliminary results.

Pain afflicts most cancer patients, mainly in the advanced and metastatic phases of the disease. Despite the existence of several guidelines for cancer pain management that are based on the recommendations by the World Health Organization and the availability of effective treatments for 70% to 90% of cases, undertreatment is well documented and can involve up to 40% of patients. Undertreatment is usually attributed to an incorrect use of opioids for reasons often conceptualized in terms of barriers related to healthcare provider, patient, family, institution, and society. In Italy, opioid consumption rates are among the lowest in Europe despite some of recent efforts to improve the analgesic prescription and utilization. In the context of a wide project coordinated by the Mario Negri Institute, a non-for-profit private foundation located in Milan, Italy, 4 activities were launched: (1) a critical appraisal of information available on the Web, with the preparation and publication of a meta-site to facilitate the use of selected resources; (2) an evaluation of prescriptions of analgesic drugs in a cohort of cancer patients using a large administrative database; (3) a nationwide outcome research study to assess the epidemiology, quality, and effectiveness of different analgesic strategies; and (4) a multimodal, community-based intervention based on information, education, and training programs to change the knowledge, opinions, and attitude toward cancer pain treatment. Activities started in 2005. Some results and outputs are already available; others will be ready by the end of 2007.
