allopurinol and Diarrhea

A dosage of 300 mg/d of allopurinol was not effective in reducing pain or improving activities of daily living in chronic pancreatitis.. Allopurinol prevents the generation of oxygen-derived free radicals by inhibiting xanthine oxidase. The purpose of this study was to determine whether allopurinol is effective in reducing pain of chronic pancreatitis.. Thirteen patients with chronic pancreatitis who were experiencing abdominal pain requiring medication at least three times each week entered a randomized, double-blind, two-period crossover clinical trial. Patients evaluated their pain daily using a categorical pain intensity scale, numeric pain intensity scale, and a visual analog scale, and weekly completed a McGill Pain Questionnaire and activities of daily living (ADL) questionnaire.. The mean baseline score of pain was approx 50% of most severe pain in all scoring systems. There was no significant decrease in pain associated with allopurinol compared to the placebo (p = 0.24-0.75). In addition, there was no benefit in terms of ADL score associated with allopurinol compared with placebo (p = 0.32). Mean uric acid level was decreased by 1.15 mg/dL while patients were taking allopurinol, compared to when they were taking placebo (p = 0.007).

Thirty patients with a diagnosis of metastatic adenocarcinoma of the lung were entered on a trial to evaluate the antitumor efficacy of 5-fluorouracil 370 mg/m2 daily for 5 days every four weeks in combination with folinic acid 200 mg/m2, 60 min prior to 5FU. All patients had a good performance status, bidimensionally measurable disease, and weight loss less than or equal to 5% of preillness weight. Of the 29 evaluable patients, only two (7%) had partial responses (95% confidence limits 1-24%). Eleven (38%) had stable disease and 16 (55%) progressed. The two responding patients survived 12 and 60+ weeks. The median survival of all evaluable patients was 25 weeks (range 7-60+) and that of the stable patients was 26 weeks. The principal toxicities observed were diarrhea and stomatitis. Myelosuppression was rarely dose limiting. In contrast to the results of treatment with 5FU and folinic acid in metastatic colorectal cancer and breast cancer, the results of treatment with this combination of agents have been much less encouraging in adenocarcinoma of the lung.

To determine the risk of adverse events associated with colchicine or non-steroidal anti-inflammatory drug (NSAID) prophylaxis when initiating allopurinol for gout.. We conducted two matched retrospective cohort studies in linked UK Clinical Practice Research Datalink and Hospital Episode Statistics datasets. Adults initiating allopurinol for gout with (1) colchicine or (2) NSAID prophylaxis were compared with those initiating without prophylaxis, individually matched by age, sex and propensity to receive the relevant prophylaxis. Weighted Cox proportional hazards models investigated associations between colchicine/NSAID and specified adverse events.. 13 945 individuals prescribed colchicine were matched to 13 945 with no prophylaxis and 25 980 prescribed NSAID to 25 980 with no prophylaxis. Adverse event incidence rates were <200/10 000 patient-years except diarrhoea (784.4; 95% CI 694.0 to 886.5) and nausea (208.1; 95% CI 165.4 to 261.7) for colchicine and angina for NSAID (466.6; 95% CI 417.2 to 521.8). Diarrhoea (HR 2.22; 95% CI 1.83 to 2.69), myocardial infarction (MI) (1.55; 95% CI 1.10, 2.17), neuropathy (4.75; 95% CI 1.20 to 18.76), myalgia (2.64; 95% CI 1.45 to 4.81), bone marrow suppression (3.29; 95% CI 1.43 to 7.58) and any adverse event (1.91, 95% CI 1.65 to 2.20) were more common with colchicine than no prophylaxis, but not nausea/vomiting (1.34; 95% CI 0.97 to 1.85). Angina (1.60; 95% CI 1.37 to 1.86), acute kidney injury (1.56; 95% CI 1.20 to 2.03), MI (1.89; 95% CI 1.44 to 2.48), peptic ulcer disease (1.67; 95% CI 1.14 to 2.44) and any adverse event (1.63; 95% CI 1.44 to 1.85) were more common with NSAID than without.. Adverse events were more common when allopurinol was initiated with prophylaxis, particularly diarrhoea with colchicine. Other events were uncommon, providing reassurance for patients and clinicians to enable shared decision-making.

The objective of this study was to estimate the association between adverse drug reactions (ADRs) and exposure to allopurinol maintenance doses higher than those in the 1984 suggested limits of Hande et al. adjusted for level of renal function.. We conducted a retrospective review of electronic health records of patients prescribed allopurinol from January 1, 2004, to June 30, 2011, to identify those who had a definite or possible ADR to allopurinol. The associations of ADRs with maintenance doses of allopurinol 1 to 1.5 times and more than 1.5 times the suggested limits of Hande et al. compared with doses within the suggested limits of Hande et al. were estimated using logistic regression models.. Of 4755 patients prescribed allopurinol, 2946 had a serum creatinine measured within 6 months of starting allopurinol, and of these, 1268 patients' records were reviewed. Forty-eight patients had a definite ADR to allopurinol, 2 of which were allopurinol hypersensitivity syndrome. The odds ratios of definite ADRs with maintenance doses of allopurinol 1.0 to 1.5 times and more than 1.5 times suggested compared with doses within suggested limits were, respectively, 1.42 (95% confidence interval [CI], 0.66-3.04) and 2.04 (95% CI, 0.87-4.77). Among those with an allopurinol maintenance dose more than 1.5 times suggested limits, the proportion of patients with a definite ADR was 2.6% (95% CI, 1.0%-5.2%).. There is no significant association of high maintenance doses of allopurinol with ADRs, and the absolute risk of ADRs at doses higher than 1.5 times the 1984 suggested limits of Hande et al. is low. Cautious, gradual increases in allopurinol maintenance doses above the suggested limits of Hande et al. are warranted if necessary to achieve a serum uric acid level less than 6 mg/dL.

Mucositis is a common complication of cytoreductive cancer chemotherapy. Stomatitis is associated with a higher risk of bacterial infection and treatment-related death. Basic oral care is recommended to reduce the incidence and severity of stomatitis. Recently, new effective prophylaxis against stomatitis has been developed such as human keratinocyte growth factor and AES-14. Gastritis can sometimes cause severe bleeding,and it may be life-threatening. It has been shown that prophylactic H2 blockers or proton pump inhibitors can reduce the incidence and severity of gastric mucosal injury. The risk for chemotherapy-induced diarrhea is significantly greater for chemotherapeutic regimens that contain irinotecan. Intestinal alkalization and Hangeshasin-to a Chinese herbal product are applied in clinical practice in Japan to prevent or reduce irinotecan-induced diarrhea,but careful monitoring,early detection and rapid cure are most important to prevent treatment-related death.

To report a case of rhabdomyolysis occurring during treatment with colchicine.. A 44-year-old African American man was admitted to the hospital due to persistent diarrhea, vomiting, and diffuse weakness. Past medical history was significant for renal failure requiring peritoneal dialysis, gout, and a new skin lesion. Approximately 2 months prior to admission, he had been started on colchicine and allopurinol. Creatine kinase concentration on admission was >14 000 U/L. Liver function tests were elevated 5 times the upper limit of normal. Colchicine was discontinued on admission. Creatine kinase concentrations decreased significantly, and strength and ambulation improved throughout hospitalization.. Colchicine was thought to be the causative factor for rhabdomyolysis in conjunction with chronic renal failure and elevated liver function tests. After discontinuation of colchicine, creatinine kinase concentrations declined and the patient's ability to walk improved. Limited case reports of colchicine-induced rhabdomyolysis have been published.. Chronic renal failure in conjunction with elevated liver function tests appear to increase the possibility of colchicine-induced toxicity, specifically, rhabdomyolysis.

Of 29 524 hospitalised medical patients monitored in a drug surveillance programme 1835 (6.2%) received the xanthine oxidase inhibitor allopurinol. After the exclusion of skin reactions adverse effects were attributed to this drug in 33 (1.8%) patients, the most frequent being haematological abnormalities (11 patients, 0.6%) and diarrhoea and drug fever (5 each, 0.3%). Adverse effects were dose-related. Reactions were unrelated to age, weight, reason for therapy, admission blood urea, or albumin concentrations. Acute exacerbation of gout was troublesome in 3 patients (1 in 600 exposed).
