Abstract
Herpes simplex virus and Cytomegalovirus co-infection has been reported to occur in a variety of sites in immunocompromised patients. To our knowledge, few cases of such co-infection have been reported to occur in the esophagus. We report a case of a 60-year-old woman who was maintained on immunosuppressive therapy for a presumed diagnosis of pemphigus vulgaris, who presented with odynophagia. Investigations revealed ulcerative esophagitis caused by both HSV and CMV. The patient was treated with valganciclovir with full recovery. We also present the results of various studies on patients with similar presentation particularly those caused by HSV and CMV co-infection.

Abstract
Despite its position at the front line against ingested pathogens, very little is presently known about the role of the esophageal epithelium in host innate immune defense. As a key player in the innate immune response, Toll-like receptor (TLR) signaling has not been well characterized in human esophageal epithelial cells. In the present study, we investigated the inflammatory response and signaling pathways activated by TLR stimulation of human esophageal cells in vitro. Using quantitative RT-PCR, we profiled the expression pattern of human TLRs 1-10 in primary esophageal keratinocytes (EPC2), immortalized nontransformed esophageal keratinocytes (EPC2-hTERT), and normal human esophageal mucosal biopsies and found that TLRs 1, 2, 3, and 5 were expressed both in vivo and in vitro. Using the cytokine IL-8 as a physiological read out of the inflammatory response, we found that TLR3 is the most functional of the expressed TLRs in both primary and immortalized esophageal epithelial cell lines in response to its synthetic ligand polyinosinic polycytidylic acid [poly(I:C)]. Through reporter gene studies, we show that poly(I:C)-induced NF-kappaB activation is critical for the transactivation of the IL-8 promoter in vitro and that nuclear translocation of NF-kappaB occurs at an early time point following poly(I:C) stimulation of esophageal epithelial cells. Importantly, we also show that poly(I:C) stimulation induces the NF-kappaB-dependent esophageal epithelial expression of TLR2, leading to enhanced epithelial responsiveness of EPC2-hTERT cells to TLR2 ligand stimulation, suggesting an important regulatory role for TLR3-mediated NF-kappaB signaling in the innate immune response of esophageal epithelial cells. Our findings demonstrate for the first time that TLR3 is highly functional in the human esophageal epithelium and that TLR3-mediated NF-kappaB signaling may play an important regulatory role in esophageal epithelial homeostasis.

Abstract
Candida oesophagitis (CO) is scarce among immunocompetent patients. This study aimed at evaluating predisposing factors, clinical symptoms and endoscopic findings in this group. We retrospectively reviewed 55 patients diagnosed as CO endoscopically (whitish plaques) and cytologically (fungal mycelia on brush cytology). Carcinoma, diabetes, acid suppression, steroids, gastric surgery and oesophageal motility disorders were considered as predisposing factors. Twenty of 55 patients lacked any predisposing factor for CO. These patients were more frequently asymptomatic (8/20) when compared with those with known predisposing factors (5/35) (p = 0.031). Moreover, dysphagia was more prevalent in the latter group (24/35 vs. 8/20; p = 0.039). Endoscopic findings correlated with the presence of neither predisposing factors nor symptoms (Wilcoxon p > 0.05). Thus, CO can be discovered in patients without apparent predisposing risk factors and clinical symptoms. Further studies are needed to elucidate the mechanisms of transition from colonisation to infection.

Abstract
AIM: Candida esophagitis is a frequent infection in immunocompromised patients. This study was designed to determine its characteristics in non-human immune deficiency virus (HIV) infected patients attending a teaching hospital.
METHODS: Clinical records of all patients coded by international classification of diseases 9th revision with clinical modifications’ (ICD-9-CM), with candida esophagitis diagnosed by esophagogastroduodenoscopy (EGD) and histopathology over a period of 5 years were studied.
RESULTS: Fifty-one patients (27 males, 24 females, range 21-77 years old and mean age 52.9 years) fulfilled the criteria (0.34% of the EGD). The common predisposing factors were carcinoma (OR 3.87, CI 1.00-14.99) and diabetes mellitus (OR 4.39, CI 1.34-14.42). The frequent clinical symptoms were retrosternal discomfort, dysphagia and epigastric abdominal pain with endoscopic appearance of scattered mucosal plaques. Another endoscopic lesion was associated with candida esophagitis in 15% patients.
CONCLUSION: Carcinomas, diabetes mellitus, corticosteroid and antibiotic therapy are major risk factors for candida esophagitis in Pakistan. It is an easily managed complication that responds to treatment with nystatin.

Abstract
Solid-organ transplantation is a therapeutic option for many human diseases. Infections are a major complication of solid-organ transplantation. All candidates should undergo a thorough infectious-disease screening prior to transplantation. There are three time frames, influenced by surgical factors, the level of immunosuppression, and environmental exposures, during which infections of specific types most frequently occur posttransplantation. Most infections during the first month are related to surgical complications. Opportunistic infections typically occur from the second to the sixth month. During the late posttransplant period (beyond 6 months), transplantation recipients suffer from the same infections seen in the general community. Opportunistic bacterial infections seen in transplant recipients include those caused by Legionella spp., Nocardia spp., Salmonella spp., and Listeria monocytogenes. Cytomegalovirus is the most common cause of viral infections. Herpes simplex virus, varicella-zoster virus, Epstein-Barr virus and others are also significant pathogens. Fungal infections, caused by both yeasts and mycelial fungi, are associated with the highest mortality rates. Mycobacterial, pneumocystis, and parasitic diseases may also occur.

Abstract
Fungal infections are associated with a high mortality rate after liver transplantation. To describe risk factors for fungal infections, 405 consecutive liver transplant recipients were analyzed. Forty-five patients (11%) developed invasive fungal infection. Median posttransplantation time to the first episode was 60 days. Pathogens were Candida species (spp) (n=24, 53%), Cryptococcus neoformans (n=10, 22%), Aspergillus spp (n=6, 13%), Rhizopus spp (n=l), and others (n=4). Presentations of infection included disseminated (n=9), intra-abdominal (n=9), esophageal (n=9), lung (n=8), blood (n=6), and central nervous system infections (n=3), and sinusitis with esophagitis (n=1). Eighteen patients (40%) with invasive fungal infection died, and 13 (72%) of these deaths were attributable to fungi. Mortality in the nonfungal infection group was 12%. Univariate analysis identified separate risk factors for Candida (intra-abdominal bleeding), Aspergillus (fulminant hepatitis), and cryptococcal (symptomatic cytomegalovirus infection) infections. In both univariate and multivariate analyses, a high intratransplant transfusion requirement and posttransplant bacterial infection were identified as significant risk factors for all types of fungal infection. The risk factor analysis reported here suggests that different pathogenic processes lead to Candida and non-Candida infection in liver transplant recipients. Their identification should prompt specific prophylactic measures to reduce morbidity and mortality in this population.

Abstract
Infections of the esophagus are unusual in the general population and strongly imply immunodeficiency, although immunocompetent individuals are not exempt. HIV infection is predominant among risk factors for infectious esophagitis. For all immunocompromised patients, the most frequently identified esophageal pathogens are Candida, CMV, and HSV. Peculiar to HIV-infected patients are idiopathic esophageal ulcers as well as unusual bacteria and parasites. Patterns of presentation differ with each infecting organism, and clinical features should be used as a guide in achieving a correct diagnosis. For example, a patient with AIDS presenting with esophageal symptoms and thrush, along with abdominal pain, nausea, vomiting, and fever, is unlikely to resolve all symptoms with empiric antifungal therapy alone. Parsimony of diagnosis does not hold among immunodeficient patients in whom concurrent infections are common. Accurate and timely diagnoses are essential as effective treatments are available for particular etiologies. Finally, among immunocompromised patients, all esophageal symptoms are not necessarily due to an infection, and possible diagnoses of pill esophagitis, acid-peptic injury, or structural and functional abnormalities should not be overlooked.

Abstract
Gastrointestinal mucosal abnormalities ranging from edema to ulceration occur in two thirds of patients dying of uremia. Early studies suggested that uremic patients on maintenance dialysis treatment were at increased risk of peptic ulceration but more recent data indicate that this is not so. Other gastrointestinal problems reported for uremic subjects on maintenance dialysis treatment include bleeding from telangiectatic lesions, constipation, mucosal deposition of amyloid and acute pancreatitis. Nausea and vomiting are common in the uremic patient but gastric emptying studies have yielded conflicting results. Patients undergoing renal transplantation are at increased risk of development of esophagitis, complicated peptic ulcer, intestinal ulceration, and perforation as well as acute pancreatitis.

Abstract
Gastrointestinal infection due to cytomegalovirus occurs frequently in liver transplant recipients. Upper gastrointestinal cytomegalovirus infection is associated with subjective complaints of nausea, a sense of abdominal fullness, and occasionally emesis and/or dysphagia. In order to determine whether these symptoms reflect a disruption of the normal motility of the stomach, the following study was performed. Eleven individuals who were evaluated for liver transplantation were prospectively recruited and studied as follows: (1) upper gastrointestinal endoscopy with biopsy of the gastric antral mucosa; (2) viral culture of the gastric mucosa; (3) a histologic examination of the gastric mucosa; and (4) a radionuclide gastric emptying study was obtained before and 4-8 weeks following successful liver transplantation. Prior to liver transplantation, none had symptoms of nausea, vomiting, or epigastric fullness. All were culture-negative for cytomegalovirus. All had endoscopic and histologic evidence of portal hypertensive gastropathy but none had antral erosions or ulcers. All demonstrated normal gastric emptying of a liquid meal. Following liver transplantation, 6 remained free of gastric cytomegalovirus while 5 developed a culture-confirmed gastric cytomegalovirus infection. Those that developed a gastric cytomegalovirus infection also had more gastric symptoms, and more gastric histologic abnormalities. Moreover, those with a gastric cytomegalovirus infection demonstrated enhanced gastric retention of a liquid meal (P less than 0.01).

Abstract
Esophageal disease is a common complication and cause of morbidity in patients with human immunodeficiency virus (HIV) infection. Opportunistic esophageal diseases may occur in patients with long-standing infection or may be the initial manifestation of HIV disease. Although a variety of both opportunistic and nonopportunistic disorders result in esophageal disease in this population, candidal esophagitis is the most common cause of symptomatic disease. Ulcerative esophagitis resulting from cytomegalovirus and idiopathic esophageal ulceration constitute the next most important etiologies. In contrast to other immunocompromised hosts, herpes simplex virus esophagitis appears to be relatively uncommon. Multiple simultaneously discovered esophageal disorders have been documented in up to 50% of patients. Opportunistic neoplasms are an infrequent cause of symptomatic disease. Candidal esophagitis may present with either dysphagia or odynophagia, and oropharyngeal candidiasis is usually present at the time of diagnosis. In contrast, ulcerative esophagitis is usually first manifested by moderate to severe odynophagia. Barium esophagography and upper endoscopy are the most commonly employed diagnostic modalities for the evaluation of the symptomatic patient. Although barium esophagography may identify specific abnormalities, this procedure appears to be relatively insensitive for the detection of mild candidal disease as well as nondiagnostic for ulcerative lesions when compared with endoscopy. In the HIV-infected patient with new-onset esophageal symptoms, an empiric trial of a systemically acting oral antifungal agent should probably be the initial management strategy. If the patient does not respond to standard therapy within 1 to 2 weeks, an endoscopic evaluation appears to be the most cost-effective diagnostic test given the diversity of potential disorders, the possibility of one or more co-pathogens or diseases, the potential for an immediate diagnosis, and the availability of mucosal biopsy to make a definite diagnosis of ulcerative or mass lesions. Given the presently available therapy for these diverse processes, establishing a definitive diagnosis in the symptomatic patient not responsive to empiric antifungal therapy is warranted.

Abstract
The effects of orthotopic liver transplantation (OLTx) and cytomegalovirus (CMV) gastroenteritis on the type of mononuclear cells within the upper gastrointestinal tract were determined. Nineteen liver transplant recipients were studied both before and after transplantation. Each underwent a pan-upper gastrointestinal endoscopy with biopsy of the antrum and duodenum before and four weeks following liver transplantation. A panel of monoclonal antibodies prepared against HLA-DR, NK, IL-2R, T11, T4, T8, and B1 cell surface antigens was used to examine the tissues. Before OLTx, none of the 19 subjects studied had clinical or histologic evidence for CMV gastroenteritis. Following OLTx, five of the 19 subjects had CMV gastroenteritis. The number of HLA-DR positive staining lymphocytes present in biopsies obtained post-OLTx was significantly greater (P less than 0.005) than those present in biopsies obtained pre-OLTx regardless of the presence or absence of CMV gastroenteritis. No difference in the intensity of HLA-DR antigen expression between pre- and post-OLTx biopsies and those with and without CMV gastroenteritis was evident. No difference in the number of natural killer (NK) cells and the number of cells expressing the interleukin-2 receptor (IL-2R) was evident between biopsies obtained pre- and post-OLTx. In contrast, the number of T lymphocytes bearing the T11, T4, and T8 markers and the calculated T4/T8 ratio differed between biopsies obtained pre- and post-OLTx and between those positive for CMV gastroenteritis post-OLTx and those without evidence for CMV gastroenteritis either before or after OLTx, although these changes were not consistent throughout the gastrointestinal tract.(ABSTRACT TRUNCATED AT 250 WORDS)
