Therapeutic Drug Monitoring (TDM) is a routinely practised clinical laboratory technique which aids the clinicians with a clear clinical judgement of the drug therapy and optimize the doses if necessary. Rifampicin is the most important and potent component of first line therapy of tuberculosis (TB). Several factors like age, weight, gender, doses and formulations, gastro-intestinal disorders, ethnicity etc alter the absorption and bioavailability of rifampicin thus altering the drug levels. Low plasma levels of rifampicin may play a plausible role in slow response to therapy, treatment failure or relapse or acquired drug resistance...

As both the rate of hypertension and cancer rise with age, concomitant hypertension in patients receiving treatment for cancer is very common. Increase in blood pressure during cancer treatment requires careful clinical assessment. Distinction between discontinuation or malabsorption of antihypertensive treatment due to factors such as nausea/vomiting/diarrhea and anti-cancer drug specific effects must be first made. De-novo hypertension during cancer treatment is likely related to anticancer drugs per se. Classical chemotherapeutic agents such as cyclophosphamide, cisplatin and busulfan have been previously linked to rising blood pressure...

Chronic infection with Norovirus is emerging as a significant risk for patients with immunodeficiency - either primary or secondary to therapeutic immunosuppression. Patients with primary immunodeficiency present a range of pathological responses to Norovirus infection. Asymptomatic infections occur and differentiating viral carriage or prolonged viral shedding after self-limiting infection from infection causing protracted diarrhoea can be challenging due to relatively mild pathological changes that may mimic other causes of diarrhoea in such patients (for instance pathogenic bacteria or parasites or graft-versus-host disease)...

BACKGROUND: Low bone mineral density (BMD) remains a frequent problem in patients with inflammatory bowel diseases (IBD). There is no general agreement regarding osteoporosis screening in IBD patients. METHODS: Cases of low BMD and disease characteristics were retrieved from 3172 patients of the Swiss IBD cohort study. Multivariate logistic regression analysis was conducted for predictive modeling. In a subgroup of 877 patients, 253 dual-energy X-ray absorptiometry (DXA) scans were available for validation...

Most patients with iron deficiency anemia are treated effectively with oral iron preparations. However, a small number of these patients are refractory to such treatments, even when the pathologic condition underlying the anemia is concurrently treated. The pathological basis for this refractoriness can be explained by several factors, including malabsorption of iron, e.g. atrophic gastritis, deficiency of other hematopoietic vitamins or minerals, e.g. vitamin B12 or zinc, other undiagnosed anemic disorders, e...

D-lactic acidosis is a rare complication that occurs mainly in patients with malabsorption due to a surgically altered gastrointestinal tract anatomy, namely in short bowel syndrome or after bariatric surgery. It is characterized by rapid development of neurological symptoms and severe metabolic acidosis, often with a high serum anion gap. Malabsorbed carbohydrates can be fermented by colonic microbiota capable of producing D-lactic acid. Routine clinical assessment of serum lactate covers only L-lactic acid; when clinical suspicion for D-lactic acidosis is high, special assays for D-lactic acid are called for...

: We investigated the association between celiac disease (CD) and bone mass density (BMD) and risk of osteoporotic fractures in the general US population. In children and men ≥18 years, CD was associated with reduced BMD, and in men ≥40 years, CD was associated with increased risk of osteoporotic fractures. INTRODUCTION: Celiac disease (CD) is an autoimmune condition, characterized by inflammation of the small intestine. CD has an increasing prevalence, and if unrecognized or untreated, CD can lead to complications from malabsorption and micronutrient deficiencies...

Cystic fibrosis (CF), a monogenic disease caused by mutations in the CFTR gene on chromosome 7, is complex and greatly variable in clinical expression. Airways, pancreas, male genital system, intestine, liver, bone, and kidney are involved. The lack of CFTR or its impaired function causes fat malabsorption and chronic pulmonary infections leading to bronchiectasis and progressive lung damage. Previously considered lethal in infancy and childhood, CF has now attained median survivals of 50 years of age, mainly thanks to the early diagnosis through neonatal screening, recognition of mild forms, and an aggressive therapeutic attitude...

Human immunodeficiency virus (HIV) epidemic has undoubtedly increased the incidence of tuberculosis (TB) globally, posing a formidable global health challenge affecting 1.2 million cases. Pulmonary TB assumes utmost significance in the programmatic perspective as it is readily transmissible as well as easily diagnosable. HIV complicates every aspect of pulmonary tuberculosis from diagnosis to treatment, demanding a different approach to effectively tackle both the diseases. In order to control these converging epidemics, it is important to diagnose early, initiate appropriate therapy for both infections, prevent transmission and administer preventive therapy...

It was hypothesized that under induced lipid malabsorption/mal-digestion conditions, an enriched sn-1(3)-monoacylglycerol oil (MAG) may be a better carrier for n-3 LC-PUFA compared to triacylglycerol (TAG) from fish oil (FO). This monocentric, double blinded clinical trial examined the accretion of EPA (500 mg/d) and DHA (300 mg/d) when consumed as TAG or MAG, into the erythrocytes, plasma and chylomicrons of 45 obese (BMI ≥ 30 kg/m(2) and 40 kg/m(2)) volunteers who were and were not administered Orlistat, an inhibitor of pancreatic lipases...

Pancreatic exocrine insufficiency (PEI) is a disease of diverse aetiology-e.g., majority of patients suffering from cystic fibrosis (CF) show PEI congenitally. Malnutrition and malabsorption of nutrients impair growth and nutritional status. As reduced fat digestion leads to a deficiency of fat-soluble vitamins the supplementation is standard, but absorption is a critical point in PEI-patients. The pancreatic duct ligated (PL) pig is an established model for PEI in humans and has been proven to be a suitable model to compare different vitamin additives for supplementation...

Background: Gastric bypass is a restrictive and malabsorptive surgery. The restrictive part consists in the creation of a small gastric pouch. The gastrointestinal bypass serves as the malabsorptive element. Aim: To describe a simplified gastric bypass approach for morbid obese patients, showing our results, and also remarking the importance of this technique for reducing the learning curve. Method: The patient is positioned in a split legs position and carefully strapped to the operating room table, with the surgeon between the patient's legs...

Iron deficiency anemia (IDA) is associated with a number of pathological gastrointestinal conditions other than inflammatory bowel disease, and also with liver disorders. Different factors such as chronic bleeding, malabsorption and inflammation may contribute to IDA. Although patients with symptoms of anemia are frequently referred to gastroenterologists, the approach to diagnosis and selection of treatment as well as follow-up measures is not standardized and suboptimal. Iron deficiency, even without anemia, can substantially impact physical and cognitive function and reduce quality of life...

Bariatric surgery is currently the most effective treatment for obesity and associated comorbidities, including rapid resolution of type 2 diabetes mellitus (T2DM). Although the weight loss itself has substantial impact, bariatric surgery also has weight loss-independent effects on T2DM. Several variations of bariatric surgery exist, including the widely studied Roux-en-Y gastric bypass and vertical sleeve gastrectomy. The success of both of these bariatric surgeries was originally attributed to restrictive and malabsorptive modes of action; however, mounting evidence from both human and animal studies implicates mechanisms beyond surgery-induced mechanical changes to the gastrointestinal (GI) system...

The proton-coupled folate transporter (PCFT-SLC46A1) is the mechanism by which folates are absorbed across the brush-border membrane of the small intestine. The transporter is also expressed in the choroid plexus and is required for transport of folates into the cerebrospinal fluid. Loss of PCFT function, as occurs in the autosomal recessive disorder "hereditary folate malabsorption" (HFM), results in a syndrome characterized by severe systemic and cerebral folate deficiency. Folate-receptor alpha (FRα) is expressed in the choroid plexus, and loss of function of this protein, as also occurs in an autosomal recessive disorder, results solely in "cerebral folate deficiency" (CFD), the designation for this disorder...

Possible toxic effects following radiation and chemotherapy of gastrointestinal tumours may cause a depletion of the mucosal barrier within the radiation volumes with severe mucositis. Diarrhoea, nausea, emesis and severe malabsorption followed by infections with dehydration and electrolyte disorders have to be encountered. For prevention and treatment of oropharyngeal mucositis an oral care protocol, oral cryotherapy together with benzydamine mouthwash may be recommended. Lower gastrointestinal diarrhoea is best treated by Octreotide (>100 μg s...
