In order to discriminate between malignant and benign effusions, the values of carcinoembryonic antigen (CEA), ferritin, beta2‐microglobulin (BMG), acid‐soluble glycoprotein (ASP), tissue polypeptide antigen (TPA), adenosine deaminase (ADA), and immunosuppressive acidic protein (IAP) were measured in the pleural fluid of 54 patients with lung cancer, 20 with malignancies other than lung cancer, 18 with tuberculous pleurisy, and 22 with benign diseases other than tuberculosis. CEA levels in malignant effusions were significantly higher than those in benign effusions. At a cutoff level of 5 ng/ml, 68% of the patients with lung cancer and 44% of the patients with other malignancies showed elevated pleural fluid CEA levels. In 13 lung cancer cases with negative pleural fluid cytology, nine cases had elevated pleural fluid CEA levels. The mean pleural fluid BMG level of patients with benign diseases was significantly higher than that of patients with malignant diseases, but there was a marked overlap between those with malignant and benign diseases. No significant differences were found in the pleural fluid ferritin, ASP, TPA, and IAP levels between malignant and benign conditions. ASP and IAP pleural fluid levels showed significant correlations with the pleural fluid C‐reactive protein (CRP) concentrations suggesting that they also reflect inflammatory activity. The mean ADA activity in tuberculous effusion was significantly higher than that resulting from other causes of pleural effusion.

The quantitative analysis on glycosaminoglycan (GAG) in the tumor tissues of five patients with malignant pleural mesothelioma and in the pleural fluid of two patients was performed with the use of biochemical methods. In the tumor tissues, it was found that the average of the total amount of GAG was more than 7.9 times as high as that in adenocarcinoma of the lung, and that hyaluronic acid and chondroitin sulfate were main constituents of mesothelioma GAG. However, there was no significant difference in the content of dermatan sulfate and heparan sulfate between this neoplasm and adenocarcinoma. In the pleural fluid, the amount of hyaluronic acid was about 40 to 230 times higher than that in adenocarcinoma of the lung with the increment of chondroitin sulfate (11–87 times). These findings suggest that a marked increase in the total amount of GAG and the elevation of either the hyaluronic acid or the chondroitin sulfate level, or both, are characteristic abnormalities in malignant pleural mesothelioma.


Haigan | 1987

Serum lipid-bound sialic acid in lung cancer patients.

Noriaki Iwahashi; Shinsuke Tamura; Junji Fujii; Souji Shimomura; Kenji Nabeshima; Toshikazu Hada; Kazuya Higashino

原発性肺癌および良性疾患患者の血清脂質結合シアル酸 (LSA) を測定した.肺癌患者のLSA値はCRP (-) 良性疾患患者の値に比べて有意に高く, cut off値を20.0mg/dlにした場合の肺癌診断のpositiverateは57.1%であった.肺癌の組織型別, 臨床病期別には有意差を認めなかったが, LSAとCEAとを組み合わせることによって肺癌診断のpositiverateは有意に上昇し, 血清LSAが有用な腫瘍マーカーになりうる可能性が示唆された.

ビルハルツ住血吸虫症は,血尿を主訴とする寄生虫疾患で,アフリカや中近東などの熱帯地方がその流行地である.今回,我々は,世界旅行中,熱帯地方滞在の際に感染したと考えられるビルハルツ住血吸虫症を経験したので報告する.患者は33才の日本人男性. 1976年より世界旅行に出発,アフリカ,東南アジア,アメリカ大陸などを旅行していた. 1983年1月,メキシコ滞在中に血尿に気づくも放置していた.同年5月,日本へ帰国後も血尿持続し,精査のため入院.尿沈渣にて多数の赤血球および寄生虫卵を認め,その虫卵よりビルハルツ住血吸虫症と診断した.血液学的には好酸球増加および血清IgEの高値を認めた.また,膀胱粘膜の生検にて粘膜内にも虫卵を認めた.治療として酒石酸アンチモン剤を投与し尿中の虫卵が陰性化し退院した.本症は,流行地では2000万~3000万人もの患者が存在してるにもかかわらず,本邦ではほとんど認めることのできないまれな輸入寄生虫疾患であるが,海外渡航が頻繁に行なわれるようになつた現在,特に本疾患流行地に滞在していた場合には,血尿を認めた時には鑑別すべき疾患の一つになりえる.

[A case of an alpha-fetoprotein producing tumor of the chest wall].

Yuji Moriwaki; Matsui K; Iwahashi N; Fujii J; Tamura S; Kenji Nabeshima; Toshikazu Hada; Kazuya Higashino

55才,男性.肝硬変にて加療中, alpha-fetoproteinの上昇をみたため精査目的にて当科に入院となつた.入院後肝シンチグラム, body CTスキャン,腹腔動脈造影を施行したが,肝癌の存在は否定的であつた.一方この間, alpha・歪etoproteinは漸増傾向にあり,ガリウムシンチグラムを施行したところ,約2年来存在する右胸壁腫瘍の部位に一致してガリウムの著明な集積をみたので,同腫瘍を経皮的に生検した.その結果,悪性上皮性胸壁鍾瘍と判明し,他に原発巣と思われる部位や転移巣を認めなかつたので摘出術を施行した.術後alpha-fetopmteinは著明に低下し, 2カ月後にはほぼ正常に復した.腫瘍中alpha・fetoproteinは1.5μg/g湿重量であつた.腫瘍の病理組織学的確診は困難であつたが,肝癌の胸壁転移あるいは胸壁発生の奇型腫群腫瘍の1型の可能性が考えられた.本腫瘍はConcanavalinAの非吸着率を考慮に入れるとyolk sac由来の腫瘍の可能性が高いと考えられるが,原発巣が非常に微小で転移巣の方が先に顕在化した原発性肝癌の胸壁転移も全く否定はできず,今後肝癌の有無のfollow upが必要と思われるが,いずれにせよ興味深い症例と考えられた.

A CASE REPORT OF TEMPORAL ARTERITIS

Kenji Nabeshima; Noboru Ohtsuru; Zenji Horai; Hidemaro Sagino

側頭動脈炎は本邦では比較的希な疾患で,その成因については免疫学的機序が関与しているといわれているが,症例報告も少なく充分判明していない.今回,筆者らは臨床像と側頭動脈生検像より本症と診断しえた症例について検索し,特に蛍光抗体法により,病変血管壁にimmunoglobulinsやcomplement factorsの存在を証明し得たので報告する.症例は67才,男性で,発熱両側頭部痛,左鼻側半盲で来院し,検査にて血沈値の著明な亢進, CRP強陽性,血清α2, γ-globulin値やfibrinogen値の増加等を示し,側頭動脈生検像で,典型的なgiant-cell arteritisの像を呈した.この病変動脈壁の蛍光抗体法による検索で,抗IgGが“cytoplasmic pattern”として,また他のimmunoglobulinsやcomplement factorsに対する抗体は“linear pattern”として観察された.治療は高度の病変動脈摘出後に副腎皮質ホルモン薬(プレドニゾロン40mg/日)の投与で,臨床症状や検査値は著明に改善し,視野欠損も著しく縮小した.これらの事実から,側頭動脈炎の病因として,何らかの免疫異常が関連していると推定される.
