Use of nucleoside analogs in patients with chronic hepatitis B in Nepal: A prospective cohort study in a single hospital.

Aim: There still remain many concerns about the present status of antiviral therapy for chronic hepatitis B in developing countries in Asia, where the monitoring systems of virological markers have not been well established, despite the high prevalence of hepatitis B virus (HBV) infection. To investigate it in Nepal, this prospective cohort study was conducted at the Teaching Hospital of Tribhuvan University in Kathmandu.

Methods: From 2007 to 2012, 65 patients were consecutively enrolled, 44 of whom received nucleoside analogs (NA), such as lamivudine (LMV), adefovir or tenofovir (TDF), on the decision of the local hepatologist.

Validation of the 3-day rule for stool bacterial tests in Japan.

Objective: Stool cultures are expensive and time consuming, and the positive rate of enteric pathogens in cases of nosocomial diarrhea is low. The 3-day rule, whereby clinicians order a Clostridium difficile (CD) toxin test rather than a stool culture for inpatients developing diarrhea >3 days after admission, has been well studied in Western countries. The present study sought to validate the 3-day rule in an acute care hospital setting in Japan.

Assessment of antigenemia assay for the diagnosis of cytomegalovirus gastrointestinal diseases in HIV-infected patients.

We conducted a single-center prospective study to evaluate the utility of cytomegalovirus (CMV) antigenemia assay for the diagnosis of CMV-gastrointestinal disease (GID). The study subjects were HIV-infected patients with CD4 count ≤200 μL/cells who had undergone endoscopy. A definite diagnosis of CMV-GID was made by histological examination of endoscopic biopsied specimen.

Factors associated with esophageal candidiasis and its endoscopic severity in the era of antiretroviral therapy.

Background: Candidia esophagitis (CE) is an AIDS-defining condition, usually occurring in individuals with low CD4 counts of <200 cells/µL. Endoscopy is a valuable definitive diagnostic method for CE but may not be indicated for asymptomatic patients or for those with high CD4 counts or without oral candidiasis. This study assessed such patients to clarify the factors associated with CE and its severity on endoscopy in the highly active antiretroviral therapy (HAART) era.

Risk factors for intestinal invasive amebiasis in Japan, 2003-2009.

We determined yearly change in prevalence and risk factors for amebic colitis caused by intestinal invasive amebiasis among persons who underwent endoscopy and assessed differences between HIV-positive and HIV-negative persons in Japan. A total of 10,930 patients were selected for analysis, of whom 54 had amebic colitis. Prevalence was in 2009 (0.

A Difficult Differential Diagnosis of Acute Cholecystitis in a Patient With Steroid-induced Diabetes.

Unlabelled: An impairment of gallbladder motility due to autonomic neuropathy may cause cholestasis and result in gallbladder stone formation. Diabetes is one of risk factors for acute cholecystitis. Diabetes and steroid use are associated with the susceptibility to bacterial infections, we are apt to diagnose steroid-induced diabetic patients manifesting symptoms of cholecystitis as having acute bacterial infective cholecystitis.

[S-1-based chemotherapy for unresectable advanced gastric cancer of the elderly or patients with renal dysfunction].

Objective: S-1 based therapy is a valued standard chemotherapy regimen for unresectable gastric cancer in Japan. S-1/ CDDP therapy has been highly effective, especially for patients under 75 years old who have good organ function. However, it is the elderly and/or patients with renal dysfunction who make up the majority of the candidates for chemotherapy in general hospitals.

[A case of candidal infection of gastric ulcers with characteristic endoscopic findings].

While Candida infection is a common opportunistic infection, Candida-associated gastric lesions are far less frequent. We report a case of gastric ulcers due to candidal infection. A 73-year-old woman had ulcers refractory to treatment with a proton pump inhibitor (PPI) and Helicobacter pylori eradication.

[Pathologic condition and prognosis of NSAids ulcer].

Recently, H. pylori infection rate has decreased and non-steroidal anti-inflammatory drugs(NSAIDs including aspirin) induced ulcers have increased more and more with aging in Japan. Pathological and clinical conditions of NSAIDs ulcer are different from that of H.

[The usefulness and limitations of the new Japanese criteria for severity assessment in acute pancreatitis].

New Japanese criteria for severity assessment in acute pancreatitis were introduced in October 2008. The new criteria are simpler than the previous ones, and are also expected to be more useful for the severity assessment. We retrospectively analyzed the clinical factors in our patients to predict prognosis, and evaluated the usefulness and limitations of the new criteria.

[A case of HIV coinfected with hepatitis B virus treated by entecavir].

A 45-year-old male active homosexual was given a diagnosis of HIV-1 and acute hepatitis B in August 2007. Since his liver function became rapidly impaired, anti-HBV therapy with oral administration of entecavir (ETV) was started, and resulted in a favorable outcome. However, serum concentration of HIV-RNA decreased by log 1.
