Progress in the understanding of the pathophysiology of irritable bowel syndrome (IBS), once thought to be a purely psychosomatic disease, has advanced considerably and low-grade inflammation and changes in the gut microbiota now feature as potentially important. The human gut harbours a huge microbial ecosystem, which is equipped to perform a variety of(More)
BACKGROUND Celiac disease is a common cause of chronic diarrhea and malabsorption syndrome all over the world. Though it was considered uncommon in India in past, it is being described frequently recently. Some patients with celiac disease do not improve despite gluten free diet (GFD). A study described 15 cases of celiac disease unresponsive to GFD in whom(More)
BACKGROUND Various causes of malabsorption syndrome (MAS) are associated with intestinal stasis that may cause small intestinal bacterial overgrowth (SIBO). Frequency, nature and antibiotic sensitivity of SIBO in patients with MAS are not well understood. METHODS Jejunal aspirates of 50 consecutive patients with MAS were cultured for bacteria and colony(More)
Biochemicals in the upper-gut aspirate in 31 patients with malabsorption syndrome (MAS) with and without small intestinal bacterial overgrowth (SIBO), and 10 disease-free controls were analyzed using high-resolution (1)H-NMR spectroscopy, and were correlated with the degree of SIBO and severity of MAS. Compared to controls, the patients had higher(More)
BACKGROUND & OBJECTIVES Aetiology of malabsorption syndrome (MAS) differs in tropical and temperate countries over time; clinical and laboratory parameters may differentiate between various causes. This study was undertaken to investigate the spectrum of MAS among Indian adults and to find out the features that may help to differentiate between TM and(More)
Pus samples obtained from 109 patients with liver abscess were examined by NMR spectroscopy. To our knowledge this is the first report on metabolic profiling of liver abscesses. Fifty metabolites were identified by combination of one (1D) and two-dimensional (2D) NMR spectra. Metabolic derangements were evaluated for differentiation between amoebic (ALA)(More)
BACKGROUND Transfusion-transmissible malaria (TTM) is a major concern in malaria endemic countries. A study was therefore conducted to know sero-prevalence of malaria in blood donors and the risk of TTM to multi-transfused patients at our hospital. MATERIALS AND METHODS STUDY SUBJECTS WERE: eligible blood donors (n = 1000), donors deferred due to history(More)
BACKGROUND Helicobacter pylori (H. pylori) has been etiologically linked with primary gastric lymphoma (PGL) and gastric carcinoma (GC). There are a few reports of occurrence of both diseases in the same patients with H. pylori infection. CASE PRESENTATION We report a patient with PGL in whom the tumor regressed after surgical resection combined with(More)
In the present study we aimed to determine (i) frequency of Cryptosporidium species among patients with renal transplantation (RT) and human immunodeficiency virus (HIV) infection and (ii) relationship of the nature, severity, and duration of symptoms with different species and load of Cryptosporidium. Stool samples from 70 (42 RT and 28 HIV) and 140(More)
Background/Aims Because Methanobrevibacter smithii produces methane, delaying gut transit, we evaluated M. smithii loads in irritable bowel syndrome (IBS) patients and healthy controls (HC). Methods Quantitative real-time polymerase chain reaction for M. smithii was performed on the feces of 47 IBS patients (Rome III) and 30 HC. On the lactulose hydrogen(More)
