Two hundred rheumatoid arthritis (RA) patients taking low dose methotrexate (MTX) were evaluated for adverse effects. During a mean follow up of 41.5 months, the mean cell volume (MCV) was elevated at some time during the course of treatment in 42 patients. The MCV was normal in the remaining 158 patients. One hundred ninety-eight patients were treated simultaneously with oral folic acid. With the exception of heartburn, which was seen more often in the high MCV group, there was no difference in the frequency of adverse effects attributable to MTX between groups. Severity of side effects and the frequency of MTX dose reduction and MTX discontinuation due to toxicity were also similar between groups. This analysis suggests that elevation of MCV in RA patients treated simultaneously with MTX and folate does not predict MTX toxicity. The authors also discuss the mechanism of action of MTX with regard to folate metabolism.

This study was performed to review information on functional and anatomic esophageal manifestations in patients with rheumatic disorders and to outline their pathogenesis, diagnosis, and treatment in light of the current medical, endoscopic, and surgical advances. A MEDLINE search of English-language articles published between 1985 and 1995, reviews of the bibliographies of textbooks, and a manual search of the reference lists of relevant articles formed the data sources, all combined with our own clinical experience. Primary research and review articles addressing the pathogenesis, diagnosis, treatment, prognosis, and complications of esophageal disease occurring in a rheumatic context were selected, with emphasis on recently developed medical, endoscopic, and surgical methods for diagnosis and management. Study design and quality were assessed, with particular attention paid to methods and aims. Relevant data on frequency, clinical presentation, and relationship to underlying rheumatic disorder, prognosis, and clinical management were analyzed. Esophageal manifestations are common in patients with rheumatic diseases and range in nature and severity from functional myopathic or neuropathic esophageal dysmotility to extrinsic lumenal compression and esophageal mucosal damage from gastroesophageal acid reflux or opportunistic infection. The primary symptoms of heartburn, dysphagia, odynophagia, chest pain, and bleeding may be directly related to the underlying rheumatic disease or may be the unwanted effects of therapy with nonsteroidal antiinflammatory drugs, immunosuppressants, or disease-modifying agents. Easily over-looked in the context of a multisystemic disease, these esophageal symptoms may be amenable to simple treatments, but frequently require a thorough assessment by modern, sophisticated diagnostic tools. In many instances, functional and structural involvement of the esophagus in patients with rheumatic disorders requires a high index of suspicion for an early diagnosis, correct assessment, intensive surveillance, and aggressive therapy to avoid end-organ damage and decline in quality of life. Significant recent advances in the understanding of esophageal pathophysiology, the development of diagnostic techniques, progress in diagnostic and therapeutic endoscopy, and minimally invasive surgery allow early detection and effective long-term therapy for esophageal dysfunction associated with rheumatic diseases.

Arthritis is a painful and disabling condition. To suppress the pain and the inflammatory process, patients are often chronic nonsteroidal anti-inflammatory drug (NSAID) users. Chronic use of NSAIDs may induce peptic ulcer, dyspeptic problems and heartburn. Therefore, these patients are often provided with treatment to relieve and/or protect against gastrointestinal problems. Rheumatic disorders also affect a range of health-related quality of life domains. In one study, patients with NSAID-associated gastroduodenal lesions complained about lack of energy, sleep disturbances, emotional distress and social isolation in addition to pain and mobility limitations. The degree of distress and dysfunction differed markedly from scores in an unselected population. Clinical trial data suggest that acid-suppressing therapy with omeprazole is superior to therapy with misoprostol and ranitidine in healing gastroduodenal lesions and preventing abdominal pain, heartburn and indigestion symptoms during continued NSAID treatment. Because arthritic patients are severely incapacitated by their condition regarding most aspects of health-related quality of life, it is important to offer a treatment that is effective in healing and preventing NSAID-induced ulcers and gastrointestinal symptoms during continued NSAID treatment without further compromising the patients' quality of life. Treatment with omeprazole once daily has been shown to be superior to that with ranitidine and misoprostol in this respect.

Coexisting diseases may have unforeseen yet clinically significant effects on patients' well-being. Both generic and disease-specific measures are frequently used to assess health-related quality of life (QOL). The present study assessed the effects of comorbidity on the results of QOL measures through an analysis of longitudinal data from 3 double-masked, randomized, placebo-controlled clinical trials dealing with heartburn, asthma, and ulcer. Patients were assigned to subgroups by comorbidity status: those with no comorbid diseases and those whose principal disease was heartburn, asthma, or ulcer and whose comorbid condition was chronic obstructive pulmonary disease, asthma, or chronic bronchitis; hypertension; migraine, coronary artery disease, or varicose veins; chronic gastrointestinal conditions; arthritis or back pain; diabetes; or depression. Multivariate analysis of covariance was used to test the study hypotheses. The study results suggest that comorbid conditions significantly and extensively affect patients' scores on generic QOL measures and estimation of treatment effect, whereas their influence on disease-specific QOL scores and estimation of treatment effect is considerably smaller. Further, the most important comorbidities in the 3 trial populations were arthritis or back pain and depression, which respectively accounted for 17% and 5% of the patient population. These findings have significant practical implications for the estimation of true treatment effects, control of comorbidity effects, and design of QOL trials.

Gastric limiting procedures have made an improvement in the lives of those patients in whom they have been successful. Not only have there been marked improvements in diabetes, hypertension, and arthritis, but there have been a number a number of other 'spin-offs', not the least of which is control of reflux esophagitis by totally eliminating the secretion of the parietal cell mass of the stomach from rising into the esophagus. We compared a group of 100 obese patients with reflux esophagitis who underwent Roux-Y gastric bypass (RYGBP) to a normalisized group of 23 patients on whom we had done Nissen fundoplications in the past. Visick grading I-II of 100% vs 87%, respectively, may indicate a superiority of RYGBP over the Nissen procedure. Although the groups and time periods are too divergent to draw statistically significant conclusions, one can see that the RYGBP population was apparently better served considering their cure of 'heartburn' and other reflux symptoms as well as their achievement of sustained weight loss.

Gastroesophageal reflux disease (GERD) is associated with a range of symptoms (typically heartburn, acid regurgitation and dysphagia), which may or may not be accompanied by endoscopically evident esophagitis. A number of studies have demonstrated that health-related quality of life (HRQoL) in reflux disease patients is significantly impaired in comparison to the general population, regardless of the endoscopic findings. Furthermore, this impairment is comparable to or greater than that observed in other chronic conditions, such as diabetes, arthritis or congestive heart failure. Impaired HRQoL in GERD patients is a result of features such as disturbed sleep, reduced vitality, generalized body pain, an impaired sex life and anxiety about the underlying cause of the symptoms. Nocturnal symptoms of reflux disease appear to have a particularly marked impact on HRQoL. The burden of illness imposed by reflux disease on HRQoL also has an impact on productivity, both at and outside work. The impact of reflux disease on productivity is significant and comparable to that caused by headache or back pain. Effective treatment is available for reflux disease, and there is evidence that this can quickly restore HRQoL to levels observed in the general population. However, poor communication between physicians and patients is contributing to unacceptable levels of patient dissatisfaction. Understanding patients' experience of GERD and its treatment through the study of HRQoL is one way to address this problem.

Systemic sclerosis (SSc) is a generalised connective tissue disease of unknown origin, which clinically shows by skin thickening and sclerosis of different extent (scleroderma) and by typical involvement of visceral organs. At the same time fibrotic and sclerotic changes occur in the blood vesel walls. SSc usually involves females at young and middle age. Myalgias, arthralgias and arthritis are nonspecific, tendon friction rubs in fingers are more typical for this diagnosis. Gastrointestinal involvement starts early in the oropharyngeal part, esophagus and proceeds into the distal parts. Fibrotic changes lead to slow transit dysmotility and pseudoobstruction and/or dilation of the bowels. The main symptoms are dysphagia, pyrosis, malabsorption and constipation. SSc produces two major patterns of abnormality within the lungs a fibrosing alveolitis or a primary pulmonary vascular disease. More frequently an insterstitial process develops which can be followed by pulmonary arterial hypertension. Cardiac involvement can also have different forms. Myocardial fibrosis usually appears at first in the conduction system by arrhythmias and various conduction blocks while pericarditis is mostly asymptomatic. Renal manifestation of SSc is observed in 8-10% patients. The most severe form--scleroderma renal crisis is characterised by the new onset of accelerated hypertension and rapidly progressive oliguric renal failure. No therapies have been proven to modify the course of SSc. Some of the drugs can affect only the skin changes. Majority of the currently applied agents have only a symptomatic effect.

This open label, multicentric, comparative clinical trial was done to compare the efficacy and tolerability of two sevelamer formulations, sevelamer carbonate, and sevelamer hydrochloride, in the treatment of hyperphosphatemia in Indian end stage renal disease (ESRD) patients. A total of 97 ESRD patients on hemodialysis, were enrolled. Patients were randomized to receive either sevelamer carbonate or sevelamer hydrochloride. All patients were evaluated every week for 6 weeks for efficacy and safety variables. Total 88 patients completed the study. After 6 weeks of therapy, there were similar reductions (P<0.0001) in mean serum phosphorus and the CaxP product both the groups. The responder rates for test and reference groups were 75%, 68.18% respectively (P=0.3474). The adverse events reported were nausea, abdominal pain/discomfort, heartburn, constipation, diarrhea, increased prothrombin time, and severe arthritis. No serious adverse events were reported. There was no significant difference between the groups for adverse events and the laboratory parameters. From the results of this multicentric, comparative, randomized clinical study on sevelamer carbonate we can recommend that sevelamer carbonate may be used as a phosphate binder in Indian chronic kidney disease patients.

Tomato and its derived products have a very interesting nutritional value in addition to prominent antioxidant, anti-inflammatory, and anticancer activities. Tomatoes are generally quite safe to eat. However, overall consumption varies from individual to individual. Indeed, either beneficial or harmful effects of plants or their derived products are closely related to quality, including the presence of biologically active compounds. On the other hand, the synthesis and accumulation of these bioactive molecules depends on many other factors, such as environmental conditions. In this sense, this review briefly highlights the relationship between the chemistry of tomato and its derived products and their beneficial or harmful effects on human health, such as gastroesophageal reflux disease or heartburn, allergies, kidney and cardiovascular disorders, prostate cancer, irritable bowel syndrome, lycopenodermia, body aches, arthritis, and urinary problems.
