To identify a group of patients who are likely to have specific liver damage (a risk group), 88 patients with lymphogranulomatosis were examined. The examination program included clinical studies, liver scanning, peripheral blood analysis, blood serum biochemistry, study of the bone marrow, liver biopsy in all the patients. Eleven patients manifested specific liver damage. In all the patients with liver lymphogranulomas, the disease ran an unfavourable course; they frequently demonstrated the symptoms of intoxication enlargement of the liver size, focal changes on the scanogram and concurrent damage to the bone marrow. According to the biochemical tests, high activity (over 200 U/l) of alkaline phosphatase was recorded exclusively in patients with the lymphogranulomatosis-induced liver damage. Nevertheless, none of the above-enumerated signs regarded separately cannot serve as criterion of the diagnosis of lymphogranulomatosis metastases to the liver. Analysis of the rate of association of individual clinical symptoms and laboratory findings demonstrated that the most informative were associations of high alkaline phosphatase activity and enlargement of the liver size, as well as association of thrombocytopenia and anemia. However, histological study of liver biopsies is the most reliable method of diagnosis of lymphogranulomatosis metastases to the liver, particularly in patients with clinical stages I-II, since in such patients with lymphogranulomatosis, specific liver damage runs an asymptomatic course.

Alkaline phosphatase enzyme activity was studied histochemically in 60 non-Hodgkin lymphomas and 10 pseudolymphomas of the skin. Among the 37 B-cell lymphomas, membrane-bound alkaline phosphatase activity was demonstrated in 8 cases. In none of the 23 cutaneous T-cell lymphomas studied could membrane-bound alkaline phosphatase be detected. Among the pseudolymphomas, 2 cases revealed alkaline phosphatase activity. It was not possible to draw any particular clinically significant conclusions from the membrane-bound alkaline phosphatase reactions. Looking for the microenvironmental conditions of lymphoproliferative processes in the skin, alkaline phosphatase-positive capillaries were seen predominantly in the T-cell lymphomas. The stromal reaction showing a proliferation of alkaline phosphatase-positive fibroblasts was more pronounced in cutaneous B-cell lymphomas. In conclusion, membrane-bound alkaline phosphatase in lymphoproliferative processes in the skin, as in the lymph node, characterize a distinct group of B lymphocytes related to follicle center cells. The clinical relevance of this finding remains to be determined.

An alkaline phosphatase isoenzyme that did not move from the origin in agarose gel electrophoresis was detected in serum from a 51-year-old woman with Hodgkin's disease. Inhibitor and heat-inactivation studies of the patient's serum alkaline phosphatase showed properties resembling those of both liver and bone isoenzymes. No immunoglobulin or high-molecular-mass complexes with the alkaline phosphatase isoenzyme were detected. The relative molecular mass (Mr) of the atypical alkaline phosphatase isoenzyme was 182 000, that of the liver alkaline phosphatase isoenzyme control 170 000. Treatment of both of these isoenzymes with neuraminidase gave a product with an Mr of 140 000. We propose that a post-translational modification increased the carbohydrate content of the liver alkaline phosphatase isoenzyme, thus changing the charge characteristics of the enzyme and decreasing its electrophoretic mobility. We believe this to be the first report of a post-translational modification in a heat-sensitive isoenzyme of alkaline phosphatase.

A double "labeled-antigen" method has been developed for the simultaneous staining of both kappa and lambda light chains in fixed paraffin sections. The method is a two step procedure utilizing a mixture of antisera against kappa and lambda light chains in the first stage, followed by the addition of a mixture of kappa antigen labeled with horseradish peroxidase and lambda antigen labeled with alkaline phosphatase. The selection of substrates yielding reaction products of contrasting color enabled the observer to distinguish kappa-containing cells (brown) from lambda-containing cells (blue). Reactive plasma cells stained either pure brown (kappa) or clear blue (lambda) in a ratio of 1.5:1. Blood vessels containing serum immunoglobulins showed a mixed brown-blue reaction, as did the Reed-Sternberg cells of some cases of Hodgkin's disease. The advantages of this double labeled-antigen method over previously reported methods for achieving double staining are discussed.

The hepatic involvement in Hodgkin's disease, histologically verified in 133 patients who underwent laparotomy or laparoscopy, proved to be singly related to the following clinical findings: result of the liver isotopic scan, liver and/or spleen enlargement, serum albumin less than or equal to 3.5 g/dl, GOT and/or GPT greater than or equal to 20 mU/ml, serum alkaline phosphatase (SAP) greater than or equal to 210 mU/ml, BSP retention at 45 min greater than or equal to 6.5% and ESR greater than or equal to 51 mm at 1 hr. Such clinical findings were jointly evaluated and further selected by means of a logistic discriminant analysis, and the simplest function with the best discriminant ability between involved and non-involved liver was made by liver scan, spleen enlargement, BSP retention and GOT (89.5% of correct diagnoses). Since the Ann Arbor clinical criteria for liver involvement showed correct diagnoses in 69-80% of the cases, more reliable criteria can be proposed. So, liver involvement is highly probably (a) when three or more of the five variables indicated above are abnormal, or (b) when a markedly abnormal liver scan is associated with alteration of at least one of the other four parameters: otherwise liver will be non-involved.

Among 87 cases of different non-Hodgkin lymphomas studied with morphologic, enzymehistochemical, and immunologic techniques, ten were found with a positive alkaline phosphatase staining reaction of the cell membranes. The ages of the seven adult patients included in this report varied between 48-85 years. Studies of cell suspensions or cryostat sections demonstrated the presence of monoclonal membrane immunoglobulins indicating a B-cell origin of these lymphomas. Investigation of peripheral blood of six patients revealed the presence of a corresponding monoclonal lymphocyte population in four. According to Rappaport's classification, lymphoblastic, poorly differentiated, and well-differentiated lymphocytic as well as histiocytic lymphoma were encountered. According to the "Kiel" classification, most lymphomas were classified in the group of follicle-center cell tumors. The clinical course of the patients was variable. Non-Hodgkin lymphomas with alkaline phosphatase positive staining do not constitute a separate entity.

Alpha-Naphthyl acetate esterase (ANAE) and fluoride resistant alpha-naphthyl acetate esterase (FRANAE) have been compared as histochemical methods to identify T lymphocytes in sections of normal and pathological human lymphoid tissues. In addition, the FRANAE method was combined with alkaline phosphatase (ALP) in order to simultaneously evaluate the relationship between T lymphocytes and fibroblastic reticular cells (ALP) positive). The "dot like" esterase positivity of T lymphocyte was better evaluated by using FRANAE when compared to ANAE because of fluoride inhibitor of the strong esterase activity of dendritic cells and most macrophages. The combined ALP-FRANAE method clearly demonstrated a large number of fibroblastic reticular cells within the T-areas in various normal and pathological tissues such as hyperplastic lymph nodes and especially in the lymph nodes and spleens from patients with Hodgkin's disease.

In this study the problems encountered in staining immunoglobulin (Ig) in sections of paraffin-embedded human lymphoma samples have been investigated. It was found that the "masking' of cytoplasmic Ig, which occurs when tissues are fixed in formol saline (the fixative employed in most previous studies), can be avoided by the use of mercury-based fixatives. When non-Hodgkin's lymphoma samples fixed in this way were studied it was found that cytoplasmic Ig labelling of both lymphoid and histiocytic cells is often attributable to non-specific uptake of serum proteins. This phenomenon probably accounts for a number of published anomalous immunoperoxidase staining results in human lymphoma (e.g. the presence of both kappa and lambda chains in the same neoplastic cell). Double immunoenzymatic labelling (using alkaline phosphatase and peroxidase) proved valuable in the elucidation of this phenomenon. When staining due to absorbed Ig was discounted it was possible to demonstrate monoclonal Ig labelling in seven out of sixteen cases of non-Hodgkin's lymphoma. In each case IgM was found in association with a single light chain type and these results were in agreement with those obtained by direct immunofluorescent labelling of cryostat sections. In a further case u chains without associated light chains were demonstrated by immunoperoxidase staining. Seven cases of Hodgkin's disease were studied by immunoenzymatic techniques. Although IgG was frequently found in Reed-Sternberg and Hodgkin's cells its presence was not attributable to non-specific uptake of serum protein since albumin was absent or only present in small amounts. These findings are in support of the macrophage origin of these cells.

A 28-year-old man with recurrent swelling of both upper eyelids was found to have increased values in several liver function tests (GOT 162 U/l, GPT 356 U/l, gamma-GT 643 U/l, bilirubin 3.0 mg/dl, alkaline phosphatase 925 U/l). Abdominal ultrasonography demonstrated lymph node enlargements up to 3 cm, dilated intra- and extrahepatic bile ducts, as well as a cyst of 3 cm size in the pancreatic tail. Endoscopic retrograde cholangiopancreatography and punch biopsy of the liver revealed sclerosing cholangitis. In addition to the eyelid swellings the patient also had protrusion of the left eyeball, blood eosinophilia (800/microliter) and marked increase in polyclonal IgG (6930 mg/dl) with lymphadenopathy suggesting the diagnosis of angioimmunoblastic lymphadenopathy with dysproteinaemia (AILD, lymphogranulomatosis X), confirmed by lymphocyte surface marker analysis. However, histological examination of a lymph node was more suggestive of a T-zone lymphoma. Treatment with ursodeoxycholic acid (250 mg three times daily) and prednisolone (initially 2 mg/kg daily) quickly led to normal biochemical values and regression of the eye changes. In addition, treatment with interferon alpha-2b (initially 3 mill. U daily for 10 days) was begun. The abnormalities in the bile ducts disappeared 6 months later. The patient has been in full remission for 25 months (prednisolone dosage reduced to 12.5/7.5 mg alternating daily and interferon alpha-2b 3 mill. U three times weekly). This response makes AILD with secondary involvement of the bile ducts the most likely diagnosis.

Alkaline phosphatase solubilized from a human Hodgkin's lymphoma cell line (L428) was compared with purified amphiphilic and hydrophilic forms of the enzyme from human liver, and with the enzyme solubilized from a cultured osteosarcoma cell line (Saos-2). Purified hydrophilic alkaline phosphatases from human placenta and intestine were also compared in some experiments. Alkaline phosphatase was released from the plasma membrane of intact lymphocytes by phosphatidylinositol phospholipase C and thus is anchored to the outside of the plasma membrane by covalently attached phosphatidylinositol. Enzyme released in this way was hydrophilic and that solubilized with Triton X-100 was amphiphilic, as assessed by adsorption to octyl-Sepharose. Lymphocyte alkaline phosphatase, when released from the membrane by phosphatidylinositol phospholipase C or solubilized by Triton X-100, had apparent M(r) values on gradient gel electrophoresis of 227 and 494 kDa, respectively. These values were consistently higher than equivalent ones obtained with enzymes purified from human liver, but were similar to those of cultured osteosarcoma cells. Isoenzyme-specific inhibitors of alkaline phosphatase showed similar patterns of inhibition between the enzyme from L428 cells and the tissue-nonspecific (liver/kidney/bone) isoenzyme from human liver. Heat stabilities were similar for the enzymes from L428 and Saos-2 (bone isoform) cell lines, but differed significantly from those of liver, intestine and placenta. We conclude that the alkaline phosphatase expressed in this lymphoma cell line (L428) has properties that most closely resemble those of the tissue-nonspecific isoenzyme found normally in osteoblasts of bone (bone isoform).
