[A case of systemic sclerosis complicated with pneumoperitoneum and pneumatosis cystoides intestinalis].

Here we report a case of systemic sclerosis (SSc) complicated with pneumoperitoneum and pneumatosis cystoides intestinalis (PCI). A 58-year-old woman who had been treated with oxygen therapy for chronic respiratory failure caused by interstitial pneumonia was admitted to Tokyo Metropolitan Ohtsuka Hospital because of abdominal fullness. On admission, laboratory data showed accelerated erythrocyte sedimentation rate, mild anemia, hypoalbuminemia, and elevated level of lactose dehydrogenase (LDH). Anti-nuclear antibodies, anti-RNP antibodies, anti-Topoisomerase I antibodies, anti-Ku antibodies, and rheumatoid factor were positive. Chest and abdominal roentgenograms showed free air under the diaphragm, dilatation of small intestine and colon, and multiple intestinal cysts. The diagnosis of pneumoperitoneum and PCI was made with laboratory findings and radiographic findings. Her symptoms did not respond to medications altering colonic motility and oxygen therapy. Finally, abdominal symptoms and radiographic findings caused by pneumoperitoneum and PCI disappeared three weeks after treatment with 1,500 mg/day of kanamycin sulfate. PCI is rarely associated with SSc. Possible pathogenic relationship between these diseases was discussed.

[A case of primary Sjögren's syndrome accompanied by transverse myelitis].

Here we report a case of Sjögren's syndrome (SS) accompanied by transverse myelitis. A 46-year-old woman with 7-year history of primary SS was admitted to Tokyo Metropolitan Ohtsuka Hospital in September 1997 because of muscular weakness in lower extremities. She had had a low grade fever, numbness, and pain in bilateral lower extremities since July 1992. Neurological examination revealed transverse myelopathy at the level of Th 4, and peripheral neuropathy in lower extremities. Cerebrospinal fluid analysis showed slight elevation of protein and the cell count. A diagnosis of transverse myelitis and peripheral neuropathy presenting as neurologic manifestations of SS was made. Treatment was initiated with 30 mg of prednisolone, followed by improvement of fever and neurological findings. Although central nervous system complications of SS have been presented in Western countries, little information is available about Japanese patients. To our knowledge, this is the second case report which describes the occurrence of transverse myelitis in Japanese patients with SS.

[Lupus cystitis and peritonitis successfully treated with intravenous cyclophosphamide pulse therapy: a case report].

The patient, a 35-year-old woman, had been diagnosed as SLE since she developed butterfly rash, arthritis and hair loss with positive antinuclear antibody, anti-DNA antibody, and LE cells in 1989, and treated with daily 20 mg prednisolone (PSL). She had been suffering from nausea, vomiting and waterly diarrhea since 1992. In June 1995, she noted pollakisuria and sense of residual urine, followed by dysuria and nocturia in October. She was admitted to our hospital in January 1996 with progressive gastrointestinal and urinary symptoms. Computerized tomography (CT) depicted thickening of the wall of intestine and bladder, diminished volume of bladder, and bilateral hydronephrosis and hydroureter. Biopsy of the bladder revealed erosion of mucosa and moderate infiltration with inflammatory cells. The diagnosis of lupus cystitis and peritonitis was made and she was initially given intravenous methylprednisolon pulse therapy (500 mg/day) for 3 days, and then switched to 100 mg of daily intravenous PSL. She responded partially to this regimen, but gradually developed gastrointestinal and urinary symptoms again when PSL was tapered down to 70 mg/day. Therefore, monthly intravenous cyclophosuphamide pulse therapy was started. With this therapy, her bladder and bowel symptoms improved, and then the thickness of her bladder and intestinal wall, and the bladder volume normalized. Five months after institution of therapy, PSL was successfully tapered down to 30 mg/day and she was discharged. Intravenous cyclophosphamidepulse therapy is a choice of treatment for steroid-resistant lupus cystitis and peritonitis.

Acute sympathetic hyperfunction in overlapping syndromes of systemic lupus erythematosus and polymyositis.

A 20-year-old woman with arthralgia, serositis, thrombocytopenia, proteinuria, muscle weakness, elevated creatinine kinase, and positive anti-Sm antibody was diagnosed as having polymyositis and systemic lupus erythematosus (SLE). She had persistent high temperature, sinus tachycardia, hyperhidrosis, mydriasis, visual disturbance, hallucination, and loss of consciousness. Levels of plasma adrenaline, noradrenaline, and dopamine and cerebrospinal fluid interleukin (IL)-6 and IL-8 were all high. A diagnosis of sympathetic hyperfunction accompanied by central nervous system (CNS) involvement in SLE was made parenteral. Pulse administration of high dose corticosteroid therapy was effective. This is the first reported case of a connective tissue disease with CNS involvement manifesting as sympathetic hyperfunction with high plasma catecholamine levels.

[A patient with acute sarcoidosis associated with fever, polyarthritis, and erythema nodosum: a typical of Löfgren's syndrome].

A 26-year-old female was admitted to Aoyama Hospital in February 1996, for evaluation of abnormal chest shadows and polyarthritis. She visited our clinic in December 1995 with complaints of fever, fatigue, and polyarthralgia which lasted for 3 weeks. Two weeks later she developed erythema nodosum on her lower legs with the exacerbation of polyarthritis. Erythrocyte sedimentation rate was 108 mm/hr and CRP 4.9 mg/dl. A chest radiograph showed hilar lymphadenopathy and multiple nodular shadows in both lung fields. On admission, she had arthritis of the shoulders and knees, erythema nodosum on her lower extremities, and keloid-like skin lesion on her left knee. Thoracoscopic lung biopsy of nodular lesion and skin biopsy of keloid-like lesion revealed noncaseating granuloma of epithelioid cells with lymphocytes, macrophages, and giant cells, confirming the diagnosis of sarcoidosis. She was cured in three months, and was well and free of the symptoms thereafter. Löfgren's syndrome is acute sarcoidosis, characterized by arthritis, erythema nodosum, and bilateral hilar lymphadenopathy. This syndrome is common in Europe and is closely related to HLA-B8 and DR-3. The frequency of HLA-B8 and DR-3 in Japanese is almost 0%, explaining the rare onset of this syndrome in Japan. Our case is the second report of typical Löfgren's syndrome in Japan, although the patient did not have these HLA loci.

[Pneumoperitoneum with systemic sclerosis].

We report a case of systemic sclerosis (SSc) complicated with benign pneumoperitoneum without apparent pneumatosis cystoides intestinalis (PCI). A 43-year-old woman was admitted to our hospital because of prominent abdominal distension in April 1997. Raynaud's phenomenon has been detected since 1991. She was suffering from recurrent diarrhea, constipation, and subileus. The diagnosis of SSc was made in 1996 based on the sclerosis in her face, forearms, and chest, and hypomotility of the esophagus. On admission, she presented no signs of peritoneal irritation. The laboratory data revealed that white blood cell count was 7,400/mm3 and C-reactive protein was 0.1 mg/dl. Chest and abdominal roentgenograms showed massive free air under the diaphragm, dilatation of small and large intestine, and air-fluid level. PCI was not apparent. Pneumoperitoneum was improved after four weeks with intravenous hyperalimentation. But she presented recurrent severe diarrhea and high fever whenever she tried to take food orally. Klebsiella pneumoniae was proved in her jejunal juice by bacteriologic examination. Intravenous prostaglandin F2 alpha and oral fosfomycin calcium intake made her condition better. Benign pneumoperitoneum without PCI is rarely reported in the patients with SSc. In her condition, weakness of intestinal wall, hypomotility of intestine, unusual bacterial overgrowth, and elevated intraluminal pressure made intraluminal gas go through the wall of the fragile intestine of SSc. As operation of intestine of SSc usually cause miserable outcome, pneumoperitoneum accompanied with SSc even if PCI is apparent or not must be treated with conventional manner while there is no signs of peritoneal irritation.
