We describe two pregnancies of a young woman with mixed connective tissue disease. In June 1983, she was diagnosed as having Raynaud's phenomenon, arthralgia, and proteinuria. She then developed nephrotic syndrome. Methylprednisolone was initially prescribed at a large dose of 1 g/day which was slowly tapered to 5 mg/day. The proteinuria disappeared. During both pregnancies (the first beginning in December 1988 and the second in May 1992), the patient was placed on a prednisolone maintenance dose (5 mg/day). Both neonates were born healthy at term with no complications. Continuing prednisolone may be useful in pregnant women, and aggressive treatment to prevent mixed connective tissue disease exacerbation may be appropriate during pregnancy.

The aim of the study was to determine the efficacy of an individual treatment schedule in patients with systemic vasculitis. Clinical, laboratory, morphological and immunological data before and after treatment were followed in 18 patients: eight with microscopic polyangiitis, two with Wegener's granulomatosis, four with leukocytoclastic vasculitis and four with necrotizing/crescentic glomerulonephritis. Patients received individual treatment for 14.89+/-13.9 months according to the disease activity. Methylprednisolone pulse therapy (PT) was given to 16 patients, mean 1.94+/-0.4 PT/patient, followed by a slowly tapered oral dose (0.7-1 mg/kg). Cyclophosphamide PT was received by 15 patients, mean 3.13+/-0.9/patient in doses of 8-10 mg/kg, followed by an oral dose of 1 mg/kg for 9.17+/-1.9 months. Four additional patients were treated with cyclosporin A for 3 months. Eleven patients received heparin for 30 days. Plasmapheresis was provided in seven patients. Two patients were treated with azathioprine and one patient with mycophenolate mofetil. There were no significant changes in serum creatinine and creatinine clearance during the observation period. Proteinuria and haematuria improved after treatment. Kidney function improved or became stable in 66.67% of patients. No patient required haemodialysis. Haematuria was no longer observed at the end of the study in nine of 11 patients. Thirteen patients (72.22%) had clinical remission. Relapses occurred in five patients. Kidney re-biopsies showed a decrease in morphological changes in 57.2%. In conclusion, individual treatment is more flexible and controls the disease activity better.

From January 1985 to July 2000, a retrospective study of 53 patients in Taiwan was performed in order to evaluate the underlying diseases causing heavy proteinuria and the clinical outcome in children under 2 years of age (33 boys and 20 girls). Renal biopsy or autopsy was performed in 26 of the children. Renal pathology revealed 2 patients with congenital nephrosis (CNS) (7.7%), 4 with diffuse mesangial sclerosis (DMS) (15.4%), 4 with minimal change nephrotic syndrome (MCNS) (15.4%), 5 with focal segmental glomerulosclerosis (FSGS) (19.2%), 9 with IgM nephropathy in (34.6%), and 2 with hepatitis B virus-associated membranous glomerulonephritis (7.7%). Based on available histology and family history of heavy proteinuria progressing to end-stage renal disease (ESRD), patients were divided into two groups. Group I comprised 10 patients, including CNS (2 cases), DMS (4 cases), and 4 children with a familial history of heavy proteinuria progressing to ESRD. All patients in group I were initially steroid resistant. After methylprednisolone pulse therapy plus cyclosporin A treatment, no patients with CNS or DMS responded, but the other 4 patients experienced a remission. Group II comprised 43 patients; 19 patients (44.2%) were initially steroid resistant. Of these steroid-resistant patients, all experienced remission after methylprednisolone pulse therapy plus cyclosporin A, except 3 children with FSGS. One experienced a thromboembolic event during his clinical course. In conclusion, steroid-resistant nephrotic syndrome (NS) was more common than steroid-sensitive NS in Chinese patients under 2 years of age. Patients with CNS, DMS, or a family history of heavy proteinuria progressing to ESRD had a poor prognosis. Methylprednisolone pulse therapy plus cyclosporin A treatment achieved remission in some children who were initially steroid resistant. This study indicates that children with conditions associated with poor steroid responsiveness (e.g., CNS, DMS) do not respond to immunosuppressive therapy, but other children under 2 years of age, including those with a family history of progression to ESRD, may benefit from aggressive immunosuppressive therapy.

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.

Wegener's granulomatosis is a potentially life-threatening vasculitis with widely variable presentation. Only three pediatric cases with severe central nervous system involvement are reported in the literature. Early fatal outcome as described here is exceptional. This report describes a 13-year-old female with typical skin lesions, proteinuria, and renal failure initially misdiagnosed as a Schoenlein-Henoch purpura. A kidney biopsy revealed severe extracapillary proliferation in 70% of the analyzed glomeruli but no granuloma. In spite of methylprednisolone pulse therapy and oral high-dose prednisone, end-stage renal failure was reached 4 months later, necessitating peritoneal dialysis. Three months later she presented with pulmonary hemorrhage and positive antineutrophil cytoplasmic antibodies suggesting Wegener's granulomatosis. This episode was controlled by methylprednisolone pulses. Seven months later she presented generalized seizures and coma, suggesting central nervous system involvement confirmed by magnetic resonance imaging. Methylprednisolone pulses and intravenous immunoglobulins led to neurologic improvement. Oral methotrexate was then introduced for long-term disease control. Another severe relapse of central nervous system vasculitis did not respond to any applied therapies and led to death 16 months after initial symptoms. This case emphasizes the need for activity scores to identify patients at risk for progressive systemic vasculitis requiring early and long-term aggressive immunosuppressive therapy.

A 50-year-old woman was admitted because of high fever and fatigue. Proteinuria, hematuria, and elevated BUN (47.8 mg/dl) and creatinine (3.4 mg/dl) suggested rapidly progressive glomerulonephritis. The serological study revealed all negative results for rheumatoid factor, antinuclear antibody, serum cryoglobulins, MPO-ANCA, PR3-ANCA, and anti-streptolysin O. Antiglomerular basement membrane (GBM) antibody, as assessed by ELISA, was 11 EU (normal, <10). Kidney biopsy on the eighth hospital day demonstrated pauci-immune-type crescentic glomerulonephritis without ANCA. Methylprednisolone pulse therapy (500 mg/day, 3 days) and 45 mg/day prednisolone orally were started. At 3 weeks after kidney biopsy, the anti-GBM antibody value increased from 11 EU/ml to 116 EU/ml, and MPO and PR3-ANCA were still negative. HLA type was DR8 and DR 15(2), with a genotype of HLA-DRB1*08021 and HLA-DRB1*15011. The present case suggests that HLA-DR15 plays an important role on antibody production against alpha 3(IV) NC1 autoantigen after severe nephritis or tissue damage.

A 49-year-old woman with a history of chronic hepatitis C virus infection and Hashimoto disease was admitted to our hospital because of proteinuria, hematuria, purpura, and edema in the lower extremities. Laboratory data on admission revealed proteinuria (0.2 g/day), microscopic hematuria (3+) with RBC casts, renal dysfunction(serum creatinine 1.4 mg/dl), positive anti nuclear antigen (x640, speckled type), hypocoplementemia, mixed cryoglobulinemia (type III), and hepatitis C virus infection (AST 45 IU/l, ALT 33 IU/l). MPO-ANCA level was found to be high (356 EU). In renal biopsy, most glomeruli showed crescentic formation with the weak deposition of IgG, IgM, and C3 in the mesangial area and along the capillary wall. She was diagnosed as having systemic vasculitis associated with MPO ANCA. Methylprednisolone pulse therapy followed by oral prednisolone (40 mg/day) effectively normalized MPO ANCA level. It has been reported that ANCA is found in patients with HCV-associated mixed cryoglobulinemia. Therefore, in chronic hepatitis C patients with systemic vasculitis, we should consider the possibility of ANCA-related microscopic polyangiitis and make a correct diagnosis by renal biopsy.

A 67-year-old woman with systemic lupus erythematosus (SLE) was admitted to our hospital because of lupus nephritis. Methylprednisolone minipulse therapy dramatically reduced her proteinuria; however; she then complained of general fatigue with low-grade fever. Radiological and culture studies revealed no infectious focus, but she was treated with meropenem and micafungin, considering her immunosuppressive state. Cytomegalovirus antigenemia was later determined and ganciclovir was added. She became afebrile, but complained of nausea and headache, and disorientation, without meningeal signs. Because a brain computed tomography (CT) scan showed no abnormality, we initially suspected some kind of drug interaction. Despite the discontinuation of all drugs, however, she still suffered from disturbance of consciousness. A lumbar puncture revealed yeast cells stained by India ink. A diagnosis of cryptococcal meningitis was confirmed. Though fluconazole and meropenem were administered, the patient died. Autopsy findings revealed disseminated cryptococcosis concomitant with pulmonary aspergillosis. Micafungin is a recently approved echinocandin-class antifungal agent that is now widely used in Japan because of its minimal toxicity and broadspectrum activity. However, such echinocandins have limited activity against a number of fungi. Indeed, breakthrough trichosporonosis is becoming a significant problem in patients with hematological malignancies who are receiving echinocandins. To the best of our knowledge, breakthrough cryptococcosis, as seen in our patient, has not been reported previously in patients who were receiving micafungin as an empiric antifungal therapy. This case highlights that cryptococcosis should be kept in mind as a possible breakthrough infection during the administration of echinocandins, especially in patients with cellular immunodeficiency.

A 40-year-old male developed swallowing difficulties, loss of strength, and imbalance. On admission, the patient exhibited bifacial, extremity weakness, ataxia, impaired sensation, and areflexia. Electrophysiology and nerve biopsy suggested demyelination. Spinal fluid revealed increased protein content. Plasmapheresis showed benefit, but neuropathy relapsed. At second recurrence, urine analysis showed heavy proteinuria. Renal biopsy revealed focal segmental glomerulosclerosis (FSGS). Methylprednisolone and oral cyclophosphamide were given. Long-term steroids and immunoglobulin showed steady benefit. Concurrence of chronic inflammatory demyelinating polyneuropathy and FSGS suggests synergistic cellular and humoral autoimmune mechanisms related to either cross-reactivity within antigenic targets or mimicry between neural and renal epitopes.

A 77-year-old Japanese man was referred to our hospital because of the progression of renal dysfunction. Two months prior to the admission he had been diagnosed with otitis media. Urinalysis showed proteinuria and microscopic hematuria. Blood examination revealed renal dysfunction, hepatitis C virus (HCV)infection and positive myeloperoxidase (MPO)-ANCA. A chest CT revealed small infiltrates in the right middle lobe. The renal biopsy demonstrated crescentic glomerulonephritis with tubulitis. He was diagnosed as having Wegener's granulomatosis according to the American College of Rheumatology classification criteria. Methylprednisolone pulse therapy followed by oral prednisolone improved all of the otitis media, lung infiltrates and renal function. Recently, a high prevalence of ANCA has been reported in patients with HCV. It has also been reported that the prevalence of HCV infection is high in patients with Wegener's granulomatosis. Therefore, our case points to the clinical significance of HCV infection in ANCA-associated systemic vasculitis including Wegener's granulomatosis.
