Neurologic manifestations, afflicting up to 70% of SLE patients, include psychosis, seizures, chorea, neuropathies, and stroke. MRI is useful in evaluation of lupus patients and several reports have documented cerebral atrophy or focal hyperintensities. We report an unusual MRI appearance in a 56-year-old woman with SLE, diagnosed on the basis of pleuritis, lymphopenia, anti-DNA antibodies, and neurologic involvement. She reported recent onset of Raynaud's phenomenon and generalized macular rash. She presented after two months of gradual deterioration with memory loss, flattened affect, dysphagia, dysarthria, anomia, and somnolence, without focal neurologic signs. Investigations included elevated ESR, reduced complement, normal CSF without oligoclonal bands, negative viral serology, normal hormone and vitamin levels, normal renal and hepatic function. Neuropsychologic testing showed widespread impairment (WAIS-R: FSIQ-63; WMS-69; DRS-98; RCPM-14; WAB AQ-78.8). CT was normal but MRI showed strikingly symmetric, confluent hyperintensities extensively involving cerebral and cerebellar white matter on T1 and T2 weighted scans. Basal ganglia and subependymal and subcortical white matter were spared. Treated with prednisone, the patient made a gradual, but incomplete, recovery. These MRI findings may reflect widespread vasculopathy or direct immunologic brain insult with or without immunologic blood-brain barrier disruption.

Rickettsial infections of a spotted fever group have recently been experience in Japan. Although there have been 50 cases reported by this time, they were exclusively distributed in the areas along the Pacific coast. We report in this paper the first case of spotted fever group rickettsiosis in Shimane prefecture, an area faced to the Japan Sea. A 57 year-old man with high fever, general fatigue and rash was admitted to the hospital of Shimane Medical University at the end of September 1987, who had been treated with cefaclor for a few days without effect before his visit to the University Hospital. Physical examination revealed erythematous eruption, eschar on the left side of the abdomen, and generalized lymphadenopathy. Hepatosplenomegaly was not detected. Laboratory studies showed normal leukocyte counts with relative lymphopenia, high ESR and increased CRP. Transaminase levels were slightly elevated. Paul-Bunnel and Weil-Felix tests resulted in negative. Specific immunofluorescence tests demonstrated that IgG and IgM antibodies of acute-phase serum to Rickettsia japonica, a spotted fever group rickettsia isolated from patients in Japan, were not detected, while both IgG and IgM antibody titers of convalescent-phase serum increased to 1:320. Convalescent-phase serum reacted at significantly lower titers with R.typhi as well as other pathogenic spotted fever group rickettsiae. The patient was treated with ofloxacin for six days and then with combination of ofloxacin and minocycline. It should be noted that clinical symptoms such as high fever and general fatigue disappeared during a single therapy with ofloxacin.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty hospitalized patients with newly diagnosed tuberculosis were studied prospectively with a range of in vitro and in vivo tests of immune function. Responses were compared with those of healthy controls matched for age, sex, ethnic group and diet. A series of metabolic and immunologic abnormalities was found, including evidence of undernutrition, anaemia, neutrophil leucocytosis, monocytosis, lymphopenia, hyperglobulinaemia and raised erythrocyte sedimentation rate. Some patients had accelerated, others diminished, cutaneous tuberculin hypersensitivity, and some had diminished mononuclear cell proliferative and lymphokine responses to tuberculin (purified protein derivative, PPD). The patients were not uniform in their responsiveness, but could be arranged within a spectrum which showed a relationship to crude bacillary excretion and response to treatment. 27% of patients were characterized by hypersensitivity, with normal in vitro cellular responses and skin tests to PPD, scanty bacillary excretion and rapid bacteriologic sputum conversion to negative cultures with treatment. In contrast, 30% of patients were relatively anergic with negative skin tests, reduced or absent in vitro cellular reactivity to PPD, moderate or heavy bacillary excretion and later (greater than 4 weeks) bacteriologic sputum conversion. The remainder of the patients fell between these two groups. There were no correlations between cellular immunity on the one hand, and radiological extent of disease, levels of serum immunoglobulins, peripheral white cell counts or ESR on the other. In those patients followed throughout treatment, all the abnormalities with the exceptions of arm muscle circumference and serum albumin, reverted to the normal ranges established in the control group.

Seventeen patients with Wegener's granulomatosis are reviewed. Eleven males and six females, with a mean age of 46.9 +/- 4.5 years, were followed for 35.7 +/- 9.0 months. Mean duration from time of onset of symptoms to diagnosis was 8.5 +/- 3.1 months. Constitutional symptoms (100%), lower respiratory tract involvement (93%), renal involvement (87%), and upper respiratory tract involvement (80%) were the most frequent clinical manifestations. Arthritis (60%), dermal vasculitis (60%), and inflammatory ocular disease (40%) were also common. Elevated ESR (94%), anemia (70%), and lymphopenia (77%) were frequent laboratory findings prior to treatment. Five patients had renal failure at presentation and two patients progressed from no renal involvement at presentation to renal failure at diagnosis, while five patients progressed from renal involvement without impairment at diagnosis to end-stage renal failure. Seven patients died; six of these deaths were related to active Wegener's granulomatosis. The patients with a severe systemic vasculitis, and renal involvement had a poor outcome while predominant respiratory disease had a good prognosis.

The role of the faecal stream in the maintenance of the inflammation in Crohn's disease has been studied. Small bowel effluent and a sterile ultrafiltrate of it were reintroduced into the defunctioned colon of patients with Crohn's colitis treated by split ileostomy. The systemic effect of these challenges on the patients was assessed clinically and by laboratory tests, and the effect on the local disease was assessed by endoscopy, histology, and quantitative analysis of lamina propria plasma cell populations. There was little response to the ultrafiltrate challenge. In contrast the clinical responses to challenge with ileostomy effluent were marked in some patients. One patient relapsed and eight others had clinically detectable responses. On the other hand changes in laboratory, endoscopic, histological, and morphometric tests in response to the faecal challenge were less pronounced. The only significant changes in the laboratory results were a relative lymphopenia (p less than 0.05) and a raised ESR (p less than 0.02) after seven days challenge with the effluent. The plasma cell density also increased but not significantly. In conclusion, these results suggest that factors greater than 0.22 microns in the faecal stream are responsible for the maintenance and exacerbation of inflammation in Crohn's disease.

One hundred twenty-seven biopsy specimens from clinically normal light-protected skin of 88 patients with active and inactive lupus erythematosus (LE) were examined for deposits of IgG, IgM, IgA, and C3 at the dermal-epidermal junction (DEJ). Deposits were found in 91% of those with active disease and in 33% of those with inactive disease. The finding of such deposits reflected active disease just as did a decrease in serum C3 and C4 levels, elevated anti-double-stranded DNA, the presence of LE cells, lymphopenia, and an elevation of the ESR. The presence or absence of deposits in repeated biopsy specimens indicated changing disease activity, as estimated clinically, just as did changes in the other variables mentioned. Neither immunoreactants in skin nor any other laboratory abnormality reflected renal disease or other type of organ involvement. Deposits of IgG were not more commonly found in patients with renal disease.

A case of necrobiotic xanthogranuloma without typical periorbital involvement is described at the ultrastructural level. The patient, a 58-year-old Italian man, presented in 1995 with a brief history of nodulo-papular lesions commencing on the lower limbs, and mild paraproteinemia. During 6 years of follow-up, anemia, neutropenia with marked lymphopenia, and increased ESR were found, while serum cholesterol and triglyceride levels decreased from hyper to hypo values. Systemic diseases, such as diabetes, malignancy, or extracutaneous lesions, often associated with NXG, have not developed. Conventional histology was distinctive for NXG, and immunohistochemistry confirmed that dermal histiocytes were not of Langerhans cell lineage. At ultrastructure, regeneration and degeneration ("regen-degen") features were observed in some individual deep dermal histiocytes, which have not been previously documented in the literature. Identification of giant histiocytes showing 'regen-degen'' aspects might prove to be a useful ultrastructural diagnostic marker for NXG.

Systemic Lupus Erythematosus (SLE) is a disease of many faces and great mimicry. Women of child bearing ages are the potential candidates for this disease though it may occur in any age and sex group and the clinical manifestations do not vary with sex differentiation. Etiology of SLE is still to be defined and it has a prevalence of 27.7/100,000 population with higher rate of incidence in Asian and African women. This is a prospective study done from January, 2002 to December, 2006. The objective of the study was to observe the clinical profile and outcome of patients suffering from SLE. 33 patients were diagnosed following the ARA criteria. All the patients were investigated with ANA, anti ds-DNA antibody, routine blood and urine examination and follow up was done following SLE Disease Activity Index (SLEDAI) scoring system along with routine blood and urine examination. Mean age at presentation was 27.3 years with a standard deviation of 12.5. Among them, constitutional symptoms were present in 91% of the patients, hematological features were also present in 91% of patients where anemia was almost universal, one patient was suffering from autoimmune hemolytic anemia and 4 patients had thrombocytopenia. Mild leucopenia and lymphopenia was also observed in 33% patients. 60% patients show an ESR higher than 100 mm in 1st hour. Musculoskeletal and cutenous features were present in 81% and 75% cases respectively. 36% patients had some degree of renal involvement at the time of diagnosis. 6% patients had severe neuropsychiatric features. After appropriate management 52% patients leading a normal life with medication, 30% patients had a fluctuating course, 9% patients died and 9% lost follow up. Outcome was better in the patients who were diagnosed and treated early.

Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown aetiology. The results of experimental studies point to the involvement of innate immunity receptors-toll-like receptors (TLR)-in the pathogenesis of the disease. The aim of the study was to assess the expression of TLR3, 7, and 9 in the population of peripheral blood mononuclear cells (PBMC) and in B lymphocytes (CD19(+)), T lymphocytes (CD4(+) and CD8(+)) using flow cytometry. The study group included 35 patients with SLE and 15 healthy controls. The patient group presented a significantly higher percentage of TLR3- and TLR9-positive cells among all PBMCs and their subpopulations (CD3(+), CD4(+), CD8(+), and CD19(+) lymphocytes) as well as TLR7 in CD19(+) B-lymphocytes, compared to the control group. There was no correlation between the expression of all studied TLRs and the disease activity according to the SLAM scale, and the degree of organ damage according to the SLICC/ACR Damage Index. However, a correlation was observed between the percentage of various TLR-positive cells and some clinical (joint lesions) and laboratory (lymphopenia, hypogammaglobulinemia, anaemia, and higher ESR) features and menopause in women. The results of the study suggest that TLR3, 7, and 9 play a role in the pathogenesis of SLE and have an impact on organ involvement in SLE.
