The medical records of 114 consecutive HIV-infected patients with oropharyngeal and esophageal candidiasis, in whom esophagoscopy was performed, were reviewed. Esophageal candidiasis and isolated oral candidiasis were found in 75% and 25% of patients, respectively. Esophageal candidiasis was the AIDS-defining illness in 65 patients and dysphagia was the commonest symptom, but asymptomatic Candida esophagitis was observed in 43% of them. Symptoms were present in six patients with oropharyngeal candidiasis; three of them had a normal esophagoscopy and the other three had acute nonfungal esophagitis. Invasive fungal esophagitis was confirmed by biopsy in 47/74 patients (64%). The patients with esophageal candidiasis had lower CD4+ cell counts (129/microliter) and CD4:CD8 ratios (0.23) than those with oropharyngeal candidiasis (CD4 179/microliter; CD4:CD8 0.35). Thirty-six patients with esophageal candidiasis were treated with fluconazole, 100 mg/daily, for 28 days, and another 34 patients received the same dose for 10 days. A similar efficacy was seen in both regimens, but a higher incidence of oropharyngeal fungal colonization and liver dysfunction was observed in the longer therapy (p < 0.001). We conclude that asymptomatic C. esophagitis is common in HIV-infected patients. Patients with oropharyngeal candidiasis may complain of esophageal symptoms; it could be due to superficial C. infection or another not-identified opportunistic infection. More severe immunologic impairment was required to develop esophageal candidiasis than oropharyngeal candidiasis. A short course of 10 days of fluconazole therapy could be the standard regimen for the treatment of C. esophagitis in AIDS.

Fifty to eighty per cent of patients with AIDS-related complex or AIDS have gastrointestinal symptoms, the most common being dysphagia, diarrhea, or perianal lesions. The symptomatology varies from a mild "gay bowel syndrome" to a severe "diarrhea wasting syndrome". In patients with lymphadenopathy syndrome and AIDS the mucosal CD4/CD8 ratio is decreased, and the IgA-producing plasma cells of the mucosa are diminished in number as compared with HIV-negative controls. AIDS enteropathy, the etiology of which remains unclear, seems to be associated with direct infection of the intestinal mucosal cells with HIV. Clinical and therapeutic aspects of some opportunistic infections, such as Candida albicans, cytomegalovirus, and Herpes simplex virus-infection are discussed in this part.

A 46-year-old woman presented progressive proximal weakness and dysphagia. Her serum creatine kinase and myoglobin levels were markedly elevated. Chest X-rays revealed bilateral swelling of the hilar lymph nodes. Needle electromyography demonstrated active denervation and early recruitment. MRI of her skeletal muscle showed focal high intensities on T1-weighted images that were associated with diffusely increased signal intensities on T2-weighted images. Muscle biopsy revealed infiltration of inflammatory cells associated with non-caseating granulomas, and there was widespread segmental fiber necrosis, where necrotic fibers appeared regardless of these granulomas. Immunohistochemical analysis of the surface markers of the infiltrating cells showed CD68- and CD4-positive cells infiltrating into the central area of the granuloma, while CD8-positive cells infiltrating into the endomysium and the periphery of the granulomas. The characteristic histology of the granuloma confirmed the diagnosis of sarcoidosis. The diffuse muscle pathology was consistent with the patient's severe clinical course.

We report on a 48-year-old man with idiopathic hypertrophic cranial pachymeningitis (IHCP) manifesting headache, facial pain, and tongue pain with unilateral atrophy, dysarthria, and dysphagia. Although steroid therapy ameliorated these symptoms, they recurred after he developed steroid-induced diabetes mellitus. We treated the patient by lymphocytapheresis (LCP), which resulted in an improvement of his symptoms, a reduction in the CD4 lymphocyte population, a reduction of the CD4/CD8 ratio, and a reduced thickening of the dura mater that lasted for more than 14 months. Results presented here suggest that LCP can be effective in the treatment of IHCP.

In 1996, one hundred health histories of HIV serum positive patients were reviewed using the Elisa and Western Blot techniques at the Arzobispo Loayza National Hospital. Such cases were defined according to Case Definition 1987 CDC/WHO. 70% of HIV serum positive patients showed gastrointestinal symptoms according to the first medical examination. 57% of the patients were younger than 30 years old, most of them were men (men/ women ratio: 2.7/1). 59% of the patients were heterosexual, 26% bisexual, and 15% homosexual. Chronic diarrhea was the main symptom, characterized by watering depositions over 10c/d. Giardia lamblia was isolated in 32% of the cases, while Isospora Belli in 16% and Criptosporidium in 12.5%. The laboratory findings of 7 patients (12.5%) were negative. Patients showed more than 10% weight loss. 10% of the patients had an anorectal disease while 7 of the patients (10%) had an hepatic-billiary disease. The odynophagia and dysphagia were explained by oropharyngeal candidiasis. 2.8% of the patients had acalculous cholecystitis; 2.8% suffered from acute pancreatic disease and 1.4% ascitis. The hepatic biochemistry was affected by the serum albumin reduction, the transaminases increase over 2-3 times compared to normal levels and the alkaline phosphatase, bilirrubina was about 5 mg. The high endoscopic diagnostic was in connection to the candida esophagitis and inflammatory pathology. In proctoscopy, condyloma acuminatum and perianal fistula were the most usual findings. The counting of CD4 leukocytes in 20 patients showed a great reduction of CD4 lymphocytes, in values lesser than 200 cel/mm3. The relation CD4/CD8 goes from 0.01 to 0.91 rates.

Many institutionalized elderly patients are at risk of undernutrition as a result of oropharyngeal dysphagia (OD) that possibly affects their immunological status. Tube enteral fed (TEF) patients on controlled intake of nutrients enables us to evaluate the effect of inadequate nutrition on the immune system in the orally fed elderly with OD. The aim of our study was to compare CD4 lymphocyte count and CD4/CD8 ratio between these two differently fed groups. Twenty-eight orally fed patients with OD in the Functional Outcome Swallowing Scale (FOSS) stage 2 (group A) and 17 TEF subjects (group B) were studied. CD4 and CD8 counts were determined by flow cytometry. Nutritional markers (albumin, hemoglobin, and basal metabolic index) were recorded for each group. The Charlson index was used for comparison of comorbidity between the two patient groups. The average count of CD4 lymphocytes was significantly lower in group A than in group B (754 +/- 365 vs. 1032 +/- 404 cells/ml, p < 0.01). Six patients in group A (21%) had a CD4 count of less than 400 cells/ml (lower threshold) while all the patients in group B had a CD4 count of over 500 cells/ml (p < 0.001). The CD4/CD8 average ratio was also significantly lower in group A (p < 0.008). Nutritional markers were within normal limits with no difference between the groups. These results confirm our presumption that a low CD4 lymphocyte count and a low CD4/CD8 ratio could prevail among elderly frail patients with dysphagia. This supports the view that under an apparently satisfactory nutritional profile these patients may be in a state of undernutrition that negatively influences their immunodefense.

We describe a patient with paraneoplastic neurologic syndrome confirmed on postmortem examination. This 42-year-old man was admitted due to general fatigue, emaciation and acute-onset disorientation. Neurological examination revealed disorientation, moderate cognitive impairment, cerebellar ataxia, bilateral limitations and nystagmus in all directions during external ocular movement, swallowing disorder, bilateral Babinski sign, sensory disturbance in the distal parts of all extremities, and Romberg's sign. T-cell lymphoma was diagnosed following biopsy of the cervical lymph node. Neurological condition improved slightly after chemotherapy, but subsequently deteriorated. At about 6 years after the disease onset, brain magnetic resonance imaging (MRI) revealed atrophy of bilateral hippocampi and the upper vermis of the cerebellum. The patient died of pneumonia after a clinical course of about 6 years and 6 months. Pathologically, neuronal loss, reactive gliosis and perivascular lymphocytic infiltration were observed in the hippocampi, cerebellum, and inferior olivary nuclei. Lymphocytes around the vessels were positive for LCA and UCHL-1, but negative for CD8 and L26, and thus were considered to be T cells. No lymphoma cell was observed in the central nervous system or lymphatic organs. Based on the pathological findings, paraneoplastic neurologic syndrome (limbic encephalitis, cerebellar degeneration and olivary pseudohypertrophy) associated with T-cell type malignant lymphoma was diagnosed. Only three other cases of paraneoplastic neurologic syndrome associated with T-cell lymphoma have been reported. In those cases, death occurred due to the deterioration of malignant lymphoma, whereas the present patient died about 6 years after the remission of malignant lymphoma. Prognosis may thus depend on the course of the malignant lymphoma. In the present patient, neurological symptoms deteriorated after remission of malignant lymphoma, and no pathological lesion were found in the lymphatic organs. Lesions in the central nervous system in paraneoplastic neurological syndromes may follow a course independent of the original malignant disease.

A 57-year-old male became aware of a subcutaneous tumor in March 2001. Histopathological examination showed peripheral T-cell lymphoma. He achieved complete remission after chemotherapy. Later the lymphoma relapsed in the subcutaneous lesion and chemotherapy was performed again. In April 2003, he developed diplopia, dysarthria, and dysphagia. Abnormal lymphoid cells were found in the cerebrospinal fluid. An immunophenotypical study disclosed that CD2, CD3, CD5, and CD8 were positive. Rearrangement of TCR was detected by Southern blotting. Cranial magnetic resonance imaging did not detect any intraparenchymal lesions, but thickening of multiple cranial nerves was detected. These nerves were homogeneously enhanced by gadolinium-DTPA. After intrathecal chemotherapy, atypical cells disappeared from the cerebrospinal fluid and thickening of the cranial nerves was resolved. Finally, lymphoma spread to the bone marrow, and the patient died in July 2003.

Eosinophilic esophagitis (EE) is a disease whose presence has exploded in clinical practice. Because of its relative novelty, the epidemiology, pathogenesis, clinical manifestations, diagnosis and treatment of EE are constantly evolving. EE was first recognized as a disease predominantly of children, but the publications in the last few years describe it like an adult disease, too. It is not known if its frequency is truly increasing in an antigen underexposed society or the disease was previously not recognized. The diagnosis requires the histologic finding of more than 20 eosinophils per high powered field in esophageal squamous mucosa. The specific antigens that initiate EE are unknown, but both food and aeroallergens are involved. The mechanisms by which EE induces esophageal dis-motility, chronic inflammation with fibrosis, and stricture formation are still unclear. The mucosa of the patients affected by EE contains increased numbers of CD8 lymphocytes, tumor necrosis factor alpha, I1-5 and eotaxin. The main symptoms in adult are: dysphagia and food impaction. Endoscopy commonly reveals strictures, mucosal rings, linear furrowing, corrugation, and white plaques. The common treatment regimens in children and adults involve the ingestion of topical corticosteroids.

Inclusion body myositis is an acquired inflammatory muscle disease belonging to the family of idiopathic inflammatory myopathy with vacuole formation. Approximately 15-28% of idiopathic inflammatory myopathy patients suffer from inclusion body myositis. Early diagnosis is very important due to the slowly progressive disease course and consecutive muscle atrophy. Inclusion body myositis is the most common chronic progressive muscle disease over the age of 50 years. Both degenerative processes including beta-amyloid accumulation and inflammatory processes, such as CD8 positive T-lymphocytes mediated cellular cytotoxicity take part in the pathomechanism of the inclusion body myositis. These findings are well demonstrated by the parallel presence of vacuolized muscle fibers rarely invaded by T cells and intact muscle fibers invaded by inflammatory T-cells in biopsy specimens. MHC-I/CD8 complex was introduced into the newly revised diagnostic criteria as a specific immune marker which helps to differentiate inclusion body myositis from aspecific inflammation present in other muscle dystrophies. Clinically both proximal and distal muscle weakness, respiratory muscle weakness and dysphagia are present. Interstitial lung disease is infrequent. Inclusion body myositis responds poorly to antiinflammatory treatment due to the predominant degenerative processes and it often results in only biochemical response instead of clinical. Diagnosis and differential diagnosis of inclusion body myositis are a very special challenge for the physician due to the diagnostic procedures which need immunohistochemical background. New therapeutic targets, monoclonal antibodies against the costimulatory molecules, anticytokine therapy may provide further improvement in the quality of life of inclusion body myositis patients.
