RESUMO

To determine the influence of patient religiosity on the outcome of treatment of hepatitis C infection, a prospective, blinded, cohort study was performed on hepatitis C-infected patients categorized as 'higher religiosity' and 'lower religiosity' based on responses to a religiosity questionnaire. Comparisons were made between high and low religiosity patients on demographics, pre-treatment laboratory values, and response to treatment. Eighty-seven patients with complete questionnaires were placed in either higher (38) or lower (49) religiosity cohort. The patients (60% female) were ethnically diverse: African-American 39%; Hispanic 31%; white 29%. African-American race (P = 0.001) and female gender (P = 0.026) were associated with higher religiosity. The frequency of being offered treatment, accepting treatment, and completing treatment was similar in both religiosity cohorts (P = 0.234, 0.809, 0.367). Fifty-six patients completed the 24- or 48-week treatment with peginterferon and ribavirin. Depression was more frequent in the low religiosity group (38.2% vs. 4.6%, P = 0.005). Sustained viral response rate at 3-6-month post-therapy was similar in the higher (50%) and lower (57.6%) religiosity cohorts (P = 0.580; n = 55). Logistic regression modeling revealed that males having higher religiosity gave greater odds of SVR than those with lower religiosity (OR 21.3; 95% CI 1.1-403.9). The level of religiosity did not affect the decision to begin treatment for chronic HCV infection and was not associated with a better treatment outcome. A higher level of religiosity was associated with less depression among patients.

RESUMO

Bilhemia or bile mixing with blood is a rare clinical problem. The clinical presentation is usually transient self-resolving hyperbilirubinemia, progressive and rapidly rising conjugated hyperbilirubinemia, or recurrent cholangitis. Endoscopic retrograde cholangiopancreatography (ERCP) plays an important role in diagnosis and management. Biliary decompression with endoscopic sphincterotomy is useful in treating these patients. If not recognized and treated in time, the condition can be fatal in a significant proportion of patients. This usually occurs after blunt or penetrating hepatic trauma due to a fistulous connection between the biliary radicle and portal or hepatic venous radical. Cases have been described due to iatrogenic trauma such as liver biopsy and percutaneous biliary drainage. However, the occurrence after trans-jugular intra-hepatic porto-systemic shunt (TIPS) is very rare. We report a case of bilhemia presenting as rapidly rising bilirubin after TIPS. The patient was managed successfully with ERCP and removal of a blood clot from the common bile duct.

RESUMO

Recent epidemiologic studies have shown that norovirus is one of the most frequent causes of acute nonbacterial gastroenteritis. Reverse-transcription polymerase chain reaction and nucleotide sequencing are the means by which the hundreds of norovirus strains have been identified, named, and classified into genogroups and genetic clusters. They are also the means by which a particular strain is traced from the source of an outbreak throughout its spread. These molecular techniques have been combined with classic epidemiology to investigate norovirus outbreaks in diverse settings, including hospitals, nursing homes, dining locations, schools, daycare centers, and vacation venues. Outbreaks are difficult to control because of the apparent ease of transmission through food, water, person-to-person contact, and environmental surfaces. Almost all patients with norovirus gastroenteritis recover completely, but hospital and nursing home outbreaks have been associated with morbidity and mortality. The diagnostic and management approach to an individual patient is to use clinical and epidemiologic findings to rule out "not norovirus." At the first sign that there is an outbreak, strict compliance with cleaning, disinfection, and work release guidelines is important to prevent further spread.

RESUMO

Acute infectious diarrhea is a yearly occurrence for most Americans, and is associated with 1 million hospitalizations and about 6000 deaths in the United States annually. Up to 80% of acute infectious diarrhea is caused by noroviruses, which produce a clinically mild illness with a predictable short course and good outcome that make laboratory testing and antimicrobial treatment unnecessary. Most diarrhea-causing bacteria and protozoa can cause a clinical illness "like norovirus"; when they do so in healthy adults neither specialized testing nor antimicrobials is required. The presence or absence of epidemiologic evidence (such as travel, hospitalization, antibiotic use, other exposures)and clinical evidence (such as diarrhea frequency and duration, severity of abdominal pain and fever, character of stool, presence of chronic illness or immune deficiency) can change the probability of "not norovirus" from as low as 8% to as high as 100%. Such probabilities guide the use of laboratory testing and antimicrobial therapy in patients who have acute infectious diarrhea.

RESUMO

GOALS: To evaluate the role of the discriminant factor in predicting mortality and deciding on treatment in acute alcoholic hepatitis. BACKGROUND: Current guidelines on the treatment of alcoholic hepatitis restrict the use of corticosteroids to patients with discriminant factor > 32 (severe disease) because of the toxicity of steroids. Less toxic forms of therapy, such as proxyphylline, may have a role in patients with lower discriminant factor, if mortality without therapy is common. STUDY: We performed a 5-year retrospective analysis comparing the outcomes of patients with mild and severe alcoholic hepatitis. Receiver operator characteristic curves were used to study the accuracy of the discriminant factor to predict short-term mortality. RESULTS: Among the 41 patients with severe alcoholic hepatitis (discriminant factor > 32) and 48 with mild alcoholic hepatitis, 16 (39%) and 8 (16.7%), respectively, died within 28 days of admission. Only 11 (32%) actually received corticosteroid therapy. The sensitivity and specificity of the discriminant factor in predicting mortality was 66.7% and 61.5%, respectively. A receiver operator characteristic curve of the discriminant factor gave the optimal value for the discriminant factor as 33, with the area under the curve being 0.666 (P = 0.0078; 95% CI = 0.531-0.801). CONCLUSIONS: Using the value of around 32 maximizes sensitivity and specificity of the discriminant factor in predicting mortality in alcoholic hepatitis. However, there is a high mortality in patients with alcoholic hepatitis and a discriminant factor less than 32. Alternative effective agents should be considered in patients with milder alcoholic hepatitis.

RESUMO

Travel is a risk factor for acquiring infection with a spore-forming protozoa: Cryptosopridium, Cyclospora, Microsporidia, and Isospora. Certain travel destinations have a high disease burden and intense exposure. Patients present with persistent diarrhea and a history of recent travel to a developing country in the tropics. Very mild infections may be underdiagnosed and may cause typical traveler's diarrhea. In a patient with a history of travel and persistent diarrhea unresponsive to the usual antibiotic and antidiarrhea treatment, stool studies for all four of these protozoa infections should be performed. If immune status is normal and the disease is mild, symptomatic therapy may suffice. Effective treatment is available for Cyclospora, Microsporidia, and Isospora.

RESUMO

GOALS: To assess the impact of upper endoscopy and biopsy on the outcome of patients with isolated thickened gastric folds found on barium upper gastrointestinal series (UGIS). STUDY: A total of 8,325 consecutive UGIS reports were reviewed to identify 182 patients who were found to have isolated thickened gastric folds. Patients with other serious radiographic abnormalities were excluded. The 182 patients were studied by a systematic review of the esophagogastroduodenoscopy (EGD) findings, gastric biopsy results, and clinical outcome. RESULTS: The study included 96 men (52.7%) and 86 women (47.3%) who had isolated thickened gastric folds on the UGIS. Seventy-four patients underwent EGD; 108 patients did not. The two groups were similar in demographic and clinical features. The EGD results were normal, 18 (24.3%); thick gastric folds, 12 (16.2%); hiatal hernia, 12 (16.2%); erythema/inflammation, 11 (14.9%); erosions, 8 (10.8%); portal gastropathy, 3 (4.1%); and gastric ulcer, 1 (1.4%). Forty-eight of the 74 EGD patients had a gastric biopsy. The findings were chronic active gastritis, 39 (81.3%); and chronic gastritis, 5 (10.4%). Evidence for H. pylori infection was present in 91.7% of the gastric biopsies. Outcome (mean follow-up, 28.5 months) was assessed in 49 patients in the EGD group and in 55 patients in the non-EGD group. There were no cases of serious or new UGI problems in either group. CONCLUSIONS: Isolated thickened gastric folds found on UGIS are frequently associated with H. pylori infection. Performing endoscopy and biopsy did not appear to alter the outcome in these patients.
