We reported 2 children with suspected primary vasculitis of mesenteric vessels. Both children were admitted to our hospital with the complaints of abdominal pain, bloody stool or diarrhea. Laboratory examination simultaneously revealed leukocytosis with dominant neutrophils, positive CRP, and hypoalbuminemia. Although prothrombin time and activated partial thromboplastin time were within normal limits, the increased levels of FDP-E, D-dimer, and von Willebrand factor activity were observed, which suggested the endothelial cell activation and the coagulation/fibrinolysis system activation. Abdominal echography and CT scanning demonstrated the edematous thickening of intestinal or colon walls probably due to the vasculitic permeability changes of mesenteric artery. During the disease courses, skin rash, bleeding tendency, arthritis and proteinuria were not observed, and no autoantibodies including anti-nuclear antibody, anti-DNA antibody, and myeloperoxidase-antineutrophil cytoplasmic antibody, were detected. Taken together, we suspected these children as restricted vasculitis of mesenteric vessels. Intravenous prednisolone was administrated, and the clinical and laboratory abnormalities recovered completely within 2 weeks. Thus, we suggested that the leukocyte counts, CRP, and the determination of von Willebrand factor and coagulation/fibrinolysis study accompanied with X-ray, echography, and CT scanning will be useful for the early diagnosis of vasculitis before the pathologic and irreversible vascular damage are demonstrated.

A 58-year-old man developed proteinuria and renal dysfunction following pneumonia caused by methicillin-resistant Staphylococcus aureus (MRSA). Vancomycin was administered, and prednisolone pulse therapy and plasmapheresis were performed. Subsequently, serum creatinine was decreased. Eight months later, creatinine and CRP were again elevated, and MRSA was detected. Vancomycin was again administered and plasmapheresis was performed. However, renal function was not improved and continuous hemodialysis was initiated. This case indicates that complete eradication of MRSA is necessary to treat MRSA-associated glomerulonephritis, and if this is not attained, a permanent loss of renal function occurs.

We report a case of leptospirosis infected in Sabah, Borneo island, Malaysia. The case is 25-year-old male who had participated in the EcoChallenge Sabah 2000 Expedition Race, a multisport event held during August 20 to September 3, 2000 at various sites in Sabah in Malaysian Borneo. He developed a high fever and headache on September 7, and he was admitted to our hospital on September 9. On admission he also had conjunctivitis and myalgias. Laboratory findings on admission revealed leukocytosis with left shift, slightly elevated transaminase levels, high CRP levels and proteinuria. Plasmodium spp. were negative on blood smears, and no bacteria were isolated from blood and feces cultures. We performed the laboratory tests for leptospirosis, based on the information about the probable leptospirosis outbreak among athletes who participated in the EcoChallenge Race, however both Leptospira antigens and antibodies were negative at that time. We diagnosed leptospirosis clinically because he manifested persistent symptoms, and minocycline 100 mg b.i.d. was administered intravenously resulting in excellent efficacy. Serum antibody tests by microscopic agglutination test (MAT) at convalescent stage revealed significant increased antibodies against Leptospira interrogans serovar hebdomadis, and the diagnosis of leptospirosis was confirmed. Infectious diseases have been global and it is important to have information concerning worldwide infectious disease situations as much as possible for accurate diagnosis.

A 35-year-old woman who had been suffering from ascites more than 3 months after the delivery of her first baby, developed generalized edema, pyrexia, pleural effusion, and right lower abdominal pain. The laboratory data revealed 5.6 g of 24-hour urinary protein, increased ESR and CRP, a positive skin test for tuberculosis, and a positive culture fortuberculous bacilli from pleural effusion. A renal biopsy showed mild proliferative glomerulonephritis, IgA and C3 depositions along the capillary loop, in the mesangium and also in the focal tubular basement membrane, and scattered membranolysis of the glomerular basement membrane in addition to paramesangial and intramembranous electron-dense deposits. A positive culture of tuberculous bacilli led anti-tuberculous drugs resulted in the complete disappearance of proteinuria, inflammation, and various organ manifestations. As far as we know, the association of tuberculosis with glomerulonephritis is an uncommon occurrence. In addition to describing this case, we also discussed the role of tuberculosis in the pathogenesis of glomerulonephritis, and reviewed the pertinent literature.

According to the widely accepted myeloma staging system, the bulk of paraprotein is the main determinant of disease stage. However, myelomatous plasma cells differ considerably in their ability to synthesize and secrete monoclonal paraprotein. We determined plasma cell secreting potential (PCSP) as the amount of M-component, divided by the percentage of marrow plasmacytic infiltration, in 240 patients with myeloma, and correlated our results with chain isotype, plasma cell morphology, severity of bone disease, well-recognized prognostic factors, such as serum LDH, CRP, albumin and beta2-microglobulin, treatment response and overall survival. PCSP was higher in IgG than in other myeloma types, and was an almost constant parameter for each individual patient, in 134/166 cases. A > 10% decrease of PCSP in 26 patients was associated with disease aggressiveness and treatment failure. Patients with MGUS had significantly higher PCSP than those with myeloma of the same chain type. Higher PCSP was associated with stage I, absence of Bence-Jones proteinuria and indolent forms of disease with lower proliferating cell nuclear antigen (PCNA) positivity, serum LDH, alpha2-globulins, CRP and beta2-microglobulin and higher albumin levels. Conversely, patients with immature/plasmablastic morphology and those with severe bone disease had lower PCSP. Good responders to treatment had significantly higher PCSP than moderate and poor responders and PCSP was strongly correlated with overall survival in IgG and IgA myeloma. In conclusion, PCSP reflects the maturation status of myelomatous cells and therefore can be used as a prognostic factor, since patients with high secreting potential represent a lower malignancy group, in comparison to those with a low secreting potential.

A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU, ALT 41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve. Disseminated intravascular coagulation syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.

Non-specific interstitial pneumonia developed as an initial manifestation in a patient with microscopic polyangiitis. A 62-year-old man was admitted to our hospital in March 2001, because of fever and intermittent myalgia of lower extremities. Chest X-ray had revealed reticular shadows in the bilateral middle and lower lung fields since 1996. Just before admission, the patient had been diagnosed as having nonspecific interstitial pneumonia (NSIP) from the specimen obtained by video-assisted thoracoscopic surgery (VATS) in another hospital. Physical examination on admission revealed bilateral episcleritis. Laboratory data showed elevated levels of CRP and KL-6, polyclonal gammaglobulinemia, positive rheumatoid factor and myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA). Sensory and motor nerve conducting velocities were delayed in left peroneal nerve, but not other nerves, suggesting mononeuropathy. Biopsied specimens of the left quadriceps revealed vasculitis of arteioles. In spite of positive proteinuria and hematuria, no pathological lesion was found in the kidney. From all of these findings, the patient was diagnosed as having microscopic polyangiitis (MPA) without renal involvement. Methylprednisolone pulse therapy followed by intravenous cyclophosphamide pulse therapy improved his clinical conditions such as pyrexia, cough, myalgia, episcleritis and respiratory symptoms with decreased titer of serum MPO-ANCA. Thereafter, the dose of prednisolone was successfully tapered to 10 mg/day without clinical relapse. In the present patient who developed demonstrated non-specific interstitial pneumonia as an initial manifestation of MPA, VATS provided useful diagnostic and prognostic information, leading to an appropriate therapeutic choice.

In view of the ongoing controversy of cardiorenal safety of selective COX-2 inhibitors (coxibs), the present study was designed to examine the effects of 2 different coxibs, celecoxib and rofecoxib, compared with a traditional NSAID, diclofenac, and placebo on renal morphology and function in salt-sensitive hypertension. Salt-sensitive (DS) and salt-resistant (DR) Dahl rats were fed with NaCl-enriched diet (4% NaCl) for 8 weeks. Diclofenac (DS-diclofenac), rofecoxib (DS-rofecoxib), celecoxib (DS-celecoxib), or placebo was added to chow from weeks 6 to 8. Immunostaining for monocytes/macrophages (ED1) and cytotoxic T lymphocytes (CD8) was performed. In addition, renal morphology and proteinuria were assessed. Renal cortex mRNA was isolated for determination of COX-2, eNOS, and CRP mRNA by real-time reverse-transcriptase polymerase chain reaction. Untreated hypertensive animals showed glomerular injury including collapsing glomerulopathy, mesangial sclerosis, mesangiolysis, extracapillary proliferation, protein drops, and an especially high grade of glomerulosclerosis (P<0.05 versus DR-placebo) and CD8-positive and ED1-positive cells (P<0.01 versus DR-placebo), which was improved by celecoxib but not by diclofenac and rofecoxib. C-reactive protein mRNA in renal cortex was increased in DS-placebo animals (P<0.05 versus DR-placebo) and normalized by celecoxib (P<0.05 versus DS-placebo), whereas eNOS mRNA was decreased in the DS-rofecoxib group (P<0.05 versus DR-placebo, DS-celecoxib, and DS-diclofenac). Proteinuria was observed in hypertensive animals (P<0.0001 versus DR-placebo), increased by rofecoxib (P<0.05 versus DS-placebo), and normalized by celecoxib (P=0.0015 versus DS-placebo). This head-to-head comparison of selective and nonselective COX inhibitors demonstrates differential effects of coxibs on renal morphology and function in salt-dependent hypertension.

A 71-year-old man was admitted with low-grade fever, a high titer of CRP and ANCA. He was diagnosed as MPO-ANCA-associated vasculitis. On admission, his renal function was normal. Proteinuria and extra renal symptoms were not recognized. Only hematuria and hyaline cast were detected. A high titer of CRP and MPO-ANCA persisted. After obtaining informed consent, a renal biopsy was performed, revealing cellular crescentic glomerulonephritis and necrotizing vasculitis. The findings of the renal biopsy indicated an early phase of ANCA-associated nephritis. After MPSL pulse therapy, renal function was in the nomal range and proteinuria and hematuria disappeared. This present case demonstrated that early diagnosis and treatment are very important to sustain normal renal function if a high titer of MPO-ANCA is recognized in an elderly person without proteinuria.

A 55-year-old man was admitted complaining of hemosputa, fever and dyspnea. The chest radiographs and computed tomography showed a diffuse alveolar filling pattern; suggesting alveolar hemorrhage. Laboratory data demonstrated renal dysfunction with hematuria and proteinuria and serum MPO-ANCA was also elevated. Respiratory failure progressed rapidly within two days. Steroid pulse therapy and plasmapheresis was performed. Thereafter, symptoms and chest radiograph findings improved dramatically. However proteinuria persisted as steroid administration was tapered. Renal biopsy demonstrated gromeluronephritis and interstitial lymphocyte infiltration. After administering a second course of steroid semi-pulse therapy, her proteinuria improved. C-reactive protein and MPO-ANCA decreased to normal levels after the initial steroid therapy, but serum amyloid A protein (SAA) gradually elevated. The second course of steroid pulse therapy normalized SAA, and proteinuria improved. Based on these findings, SAA seems to be a more sensitive marker for steroid tapering than either CRP or MPO-ANCA.
