Clinical and laboratory indicators of extent of ulcerative colitis. Serum C-reactive protein helps the most

We estimated the extent of the inflammatory mucosal lesion by colonoscopy and biopsy in 60 patients with their first attack of ulcerative colitis. Proctitis was found in 12, proctosigmoiditis in 19, left-sided colitis in 10, and extensive colitis in 19. Fourteen clinical variables and laboratory measurements (bowel frequency, stool consistency, rectal bleeding, fecal mucus/pus, temperature, pulse rate, white blood cell count, hematocrit, sedimentation rate, serum iron, serum albumin, serum alpha 2-globulin, serum C-reactive protein, and seromucoids) were determined. All the variables except rectal bleeding and hematocrit were correlated (p less than 0.001) with the extent of colitis. On stepwise discriminant analysis, only C-reactive protein distinguished proctosigmoiditis from more improved the discrimination. Cross-validation by the "jack-knife method" showed that 86.7% of patients were correctly classified, the errors consisting in underestimation of disease in 8/29 patients with extensive colitis.     

Mesalamine in the treatment of mild to moderate active Crohn's ileitis: results of a randomized, multicenter trial

BACKGROUND & AIMS: The efficacy of 5-aminosalicylic acid (mesalamine) in the treatment of flare-ups of Crohn's disease is controversial. In previous studies, different locations and pathological behavior of Crohn's disease could have obscured the efficacy of these drugs that deliver their substance in different intestinal sites. The present study tested two different mesalamine formulations with 6-methylprednisolone in mild to moderate active Crohn's ileitis. METHODS: Ninety-four patients with Crohn's ileitis (Crohn's Disease Activity Index [CDAI], 180-350) were randomly assigned to receive for 12 weeks mesalamine tablets, 4 g (35 patients); mesalamine microgranular preparation, 4 g (28 patients); and 6-methylprednisolone, 40 mg (31 patients). Mesalamine microgranular preparation was a gelatin capsule containing 400 mg of mesalamine microgranules coated with Eudragit S, which has been shown to deliver the drug in the terminal ileum. RESULTS: Patients taking mesalamine tablets experienced a decrease of CDAI median score value of 113.5 (95% confidence interval [CI], 33-149) compared with 123 (95% CI, 77-155) in the mesalamine microgranular group and 154 (95% CI, 99-197) in the 6-methylprednisolone group (P = 0.07 [NS]). Remission at the final visit occurred in 19 of 31 (61%) patients taking steroids compared with 21 of 35 (60%) patients taking mesalamine tablets and 22 of 28 (79%) patients taking microgranular mesalamine (NS). Five patients on steroids were withdrawn because of side effects, and a case of pancreatitis was related to microgranular mesalamine. CONCLUSIONS: Mesalamine in microgranular formulation seems to be equally as effective as a standard dosage of steroids in the treatment of the mild to moderate form of Crohn's ileitis.     

Retrospective analysis of adverse drug reactions induced by gemcitabine treatment in patients with non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer death in the world. Traditional chemotherapy for advanced NSCLC is often considered excessively toxic. Recent clinical trials documented that gemcitabine may represent a good therapeutical option in patients with NSCLC. Aim of our research was to retrospectively evaluate the adverse effects induced by gemcitabine in patients with NSCLC from 1 January 1997 to 31 December 2002, in clinical records of Oncology Divisions of "S. Giovanni di Dio" Hospital of Crotone, "Ospedali Riuniti" Hospital of Reggio Calabria, Hospital of Paola, and in Pneumological Oncology Division of "Mariano Santo" Hospital of Cosenza, Italy. Clinical records of patients treated with gemcitabine (1000mgm(-2) on days 1 and 8) were reviewed and following data were obtained: sex and age of the patients, histologic diagnosis and disease stage, World Health Organisation (WHO) performance status and toxic effects induced by gemcitabine. We reported that 71.6% of NSCLC patients (age range 48-77 years; 135 males, 27 females; performance status 0=53, 1=109) were eligible for our study. Side effect of gemcitabine involved gastrointestinal system (nausea, vomiting and diarrhoea) and only in the last cycles (VIII-XI) emopoiethic system (leukopenia, neutropenia, thrombocytopenia and anemia). Grade IV vomiting occurred in three patients, thrombocytopenia in two. Grade III leukopenia was observed in three patients. Other toxicities were mild. None of the patients died during chemotherapy.In conclusion, these data showed that gemcitabine present a very good tolerability in patients with NSCLC. Therefore, it could be considered as a new therapeutic agents to use as first line therapy for this disease.     

Infliximab in the treatment of severe ulcerative colitis: a follow-up study

Conventional treatment options for patients with severe steroid-refractory ulcerative colitis (UC) include intravenous cyclosporine, which is frequently burdened by toxicity, or colectomy. Preliminary data suggest a benefit of anti-tumor necrosis factor alpha (Infliximab) therapy in patients with steroid refractory UC. Thirteen patients with severe UC, refractory to therapy with methyl-prednisolone, 60 mg IV daily were treated with a single intravenous infusion of Infliximab 5 mg/kg. Ten out of 13 patients (77%) had a clinical response to therapy defined by a CAI < or = 10 on two consecutive days. Two patients (15%) underwent total colectomy because of clinical worsening; one patient refused surgery and was lost to follow-up. Infusion with Infliximab produced no significant adverse events. The mean time of follow-up was 25.6 months (range 17-24); in this period of time 8 out of 10 patients (80%) maintained clinical remission and were able to discontinue corticosteroids therapy. Infliximab appears to be an effective agent for inducing long standing remission in refractory patients with severe UC.     

Review article: medical treatment of moderate to severe Crohn's disease

The treatment for patients with Crohn's disease of moderate to severe activity includes traditional drugs, such as corticosteroids, the primary therapy for these forms of disease, able to induce the remission of symptoms in a high percentage of patients. Because of the side-effects produced by systemic steroids, a new glucocorticoid derivative, budesonide, which acts locally in the mucosa, has recently been introduced with positive results. On the assumption that intestinal bacteria play a role in the causing Crohn's disease symptoms, antibiotics are often used in the treatment of active phases, as an alternative to or in association with steroids. The most widely employed antibiotics are metronidazole and ciprofloxacin. Immunosuppressors, such as azathioprine and 6-mercaptopurine, are useful for the treatment of chronic active disease and for maintaining remission, but they have only a marginal role in the therapy of an acute flare-up of Crohn's disease. Methotrexate acts more rapidly and its use in patients with active disease resistant to standard therapy is of interest. The discovery of biological agents represents a new era in the management of patients. To date, infliximab is the more extensively studied biological therapy in the treatment of Crohn's disease and clinical studies have demonstrated its efficacy in inducing remission of refractory disease.     

Oral and topical 5-aminosalicylic acid (mesalazine) in inducing and maintaining remission in mild-moderate relapse of ulcerative colitis: one-year randomised multicentre trial

BACKGROUND: The association of oral 5-aminosalicylic acid (mesalazine) and enema is effective in treatment of mild-moderate forms of ulcerative colitis. However no study has been aimed at determining optimal duration of this association in active ulcerative colitis. AIM: To determine whether longer duration of therapy: 1. increases the rate of patients achieving remission, and 2. reduces relapse rate during the maintenance period in patients in remission. PATIENTS AND METHODS: A total of 149 patients, (89 male, 60 female), were randomly assigned to a regimen with 5-aminosalicylic acid tablets 2.4 g/day associated with 5-aminosalycilic enema 2 g/day for a 4-week (n = 73) or 8-week regimen (n = 76). After this acute therapy, patients were submitted to clinical, endoscopic and histological examinations and those in remission were assigned to a follow-up (maintenance) period with oral mesalazine alone at a dosage of 1.2 g/day. A clinical visit, including laboratory tests, at 6 months and an endoscopic-histological control at 12 months were carried out to exclude symptoms and endoscopic-histological signs of activity. Relapse of disease, i.e., presence of clinical symptoms or abnormal laboratory tests, was confirmed by endoscopy and histology. RESULTS: At end of acute phase, clinical, endoscopic and histological remission was comparable in the two groups: 42/76 (55%), in the 4-week, and 47/73 patients (64%), in the 8-week regimen. No difference was found stratifying patients according to extension of disease. Of these 89 patients in remission, 75 (34 from 4-week regimen; 41 from 8-week regimen) completed 12 months' follow-up. At end of follow-up, a similar percentage of patients in the 4-week regimen (50%) and 8-week regimen (51%) were still in remission. No significant difference between cumulative relapse rates of the two groups was found. Stratifying patients according to extension of disease, in the 8-week regimen group, those with left-sided colitis showed a higher remission rate than that of patients with diffuse colitis (66% versus 35%, p < 0.05). All regimens were well tolerated by most patients during the entire study period. CONCLUSIONS: An additional 4 weeks of topical treatment does not increase the remission rate in patients with mild-moderate active ulcerative colitis but seems to reduce the probability of relapse in patients with left-sided colitis.     

Surgical and nonsurgical hospitalization rates and charges for patients with ulcerative colitis in Italy: a 10-year cohort study

BackgroundToday we are observing an increasing incidence of ulcerative colitis associated with an improved survival of patients.AimTo analyse current rates, outcomes, and costs of inpatient care for ulcerative colitis patients of central Italy.MethodsThe cohort included 644 ulcerative colitis patients, living in the Lazio region, with diagnosis made or confirmed by the staff of a single tertiary referral centre in Rome (1997–2006). Follow-up data on hospitalization rates, costs, and colectomy rates were collected from the Regional Hospital Information System.ResultsOverall hospitalization rates were 3 times higher than those of the region's general population, reflecting excess admissions for digestive or infectious diseases (standardized hospitalizations rates for digestive-tract: 15.9; for infectious diseases: 3.5). The overall cumulative risk for colectomy was 7.5%. On the average, hospitalizations for ulcerative colitis lasted 10 days. The mean reimbursement for a ulcerative colitis-related hospitalization was EUR 5120 (€4609 for nonsurgical admissions, €8655 for surgical hospitalizations).ConclusionUlcerative colitis patients are 3 times more likely to be hospitalized than the general population. Colectomy rates in Italian ulcerative colitis patients resemble those of northern Europe, but most hospital admissions are for diagnostic procedures or medical therapy. Hospitalizations are almost twice as long as those reported in the United States although their mean cost is considerably lower.
