Serum angiotensin converting enzyme (ACE) activity was studied in 50 patients with sarcoidosis (39 active, 11 inactive sarcoidosis), as well as in 50 control patients (34 chronic lung diseases, 9 Hodgkin-disease, 7 rheumatoid arthritis). There is a significant difference (p less than 0.001) of ACE-activity between sarcoidosis patients and controls, and between active (without steroid treatment) and inactive sarcoidosis. Steroid treatment apparently lowers ACE-activity in sarcoidosis, however, without evidence for clinical improvement. Increased ACE-activity was also found in a patient with primary biliary cirrhosis.

Immunoscintigraphy (IS) using the HRS-3 Hodgkin associated monoclonal antibody (MoAb) was performed in 18 patients with Hodgkin's Disease (HD) at staging or restaging. Either F(ab')2 fragments (14 patients) or whole HRS-3 (4 patients) labeled with 77-260 Mbq 131-I were used. Whole body images, including anterior and posterior views, were taken from a digital gamma camera, within 4 to 8 hours after injection and then daily for 5 days. In one patient IS was discontinued due to iodine intolerance. Seventeen patients were evaluable: 14 showed a true positive result including 2 cases which were reviewed as anaplastic large cell lymphoma (ALCL). Nodal, splenic, bone marrow and muscle involvements were imaged, many of these sites were previously unsuspected. In 7 patients with true positive findings the Pressman Specificity Index, as measured from biopsied material, ranged from 1.5-3 in 4 patients and from 5 to greater than 100 in 3 patients. Imaging was equivocal or failed in 1 patient (lymph nodes). In 2 patients, IS imaging was truly negative due to the absence of active HD, and a false negative result occurred once (inguinal node). In none of the patients a false positive image was observed. In order to rule out non-specific iodine uptake a control, anti-ACE MoAb, labeled with 125-Iodine was injected simultaneously in 10 patients. The evaluation of the study gave a sensitivity of 87% and a good specificity. IS using radioiodine labeled MoAbs is feasible and represents a reliable non-invasive diagnostic method for the staging and follow-up of HD and ALCL.

The majority of patients with sarcoidosis in this large series have had a number of biochemical investigations performed. Abnormal calcium metabolism was demonstrated in 40% of the patients but permanent renal damage due to nephrocalcinosis as a result of persistent derangement of calcium metabolism was rare. Raised immunoglobulin levels were seen. Half the white and two-thirds of the West Indian patients had elevated IgG levels. Abnormal immunoglobulin levels carried no obvious diagnostic or prognostic significance. Raised alkaline phosphatase levels reflected space-occupying hepatic granulomas and occurred in 23% of patients. Serum angiotensin converting enzyme (SACE) was elevated in half the patients. The highest SACE activity was found in patients with severe parenchymal lung infiltration due to sarcoidosis, and the lowest levels in those with inactive disease or after successful management with steroid drugs. SACE levels were not significantly elevated in four other granulomatous conditions: Crohn's disease, primary biliary cirrhosis, Hodgkin's disease, and active tuberculosis.

Serum angiotensin-I-converting enzyme (S-ACE) is elevated in active sarcoidosis. In Hodgkin's disease (HD) there are few reports with different and contrasting results. We studied S-ACE in 23 healthy controls and in 18 untreated and unsplenectomized patients with HD. In the same cases we studied also serum lysozyme. Lysozyme concentration was significantly higher in HD patients compared with normal controls (p less than 0.01) and was independent of stage, systemic symptoms and presence of mediastinal involvement. S-ACE activity in HD patients was lower than in healthy controls, but not significantly. The correlation coefficient between the two enzymes showed that there was no significant correlation both in controls and in patients.

Monocytes purified with cell scatter monitored counterflow centrifugation were cultured in plastic (adherent) and in teflon culture bags (suspension). Sequential changes were monitored during 15 days by measuring intracellular activity of three enzymes of intermediary metabolism: glucose-6-phosphate dehydrogenase (G-6-PDH), phosphohexose isomerase (PHI) and isocitrate dehydrogenase (ICDH), and the two acid hydrolases: acid phosphatase (ACP) and N-acetyl-beta-glucosaminidase (NAG). In teflon grown macrophages a significantly lower G-6-PDH activity was seen after 15 days in comparison to plastic adherent macrophages (P less than 0.0002). For the other enzymes similar values for both culture modalities were found. The significantly, cycloheximide insensitive, higher values for G-6-PDH, PHI and ICDH in 2 h plastic adherent monocytes in comparison with plastic non-adherent monocytes, suggest a relationship between adherent capacity and the level of intermediary metabolism. The overall yield of plastic adherent macrophages after 15 days was 35% in contrast with 89% for the in suspension cultured macrophages. This corroborates the existence of adherent and non-adherent monocytes, both capable of differentiation in vitro. In 14 patients with advanced Hodgkin's disease (HD) and 14 normal controls, monocyte differentiation was studied applying both culture modalities. The enzyme levels, reflecting growth and intermediary metabolism, were similar for both groups. The adherent capacity and yield, both in teflon and in plastic, after 15 days was comparable for both groups. It was concluded that in vitro monocyte differentiation in the presence of autologous serum was qualitatively and quantitatively normal in advanced HD; this is in favour of an intrinsically normal function of monocytes in HD.

To evaluate metabolic functionality of monocytes and lymphocytes in Hodgkin's disease (HD) we studied 3 enzymes of the intermediary metabolism, G-6-PDH, PHI, ICDH, and the acid hydrolases, NAG and ACP. These enzymes were measured in purified cell fractions of 9 patients with advanced disease and 11 normal controls. The cells were isolated with cell scatter-monitored counterflow centrifugation. Enzymes were measured in the cell lysates by means of fluorimetric microassays. In the monocytes of HD patients a significantly increased G-6-PDH activity was found (P less than 0.01), indicating an enhanced activity of the hexose monophosphate shunt. The other enzymes showed no clear differences compared to normal controls. The lymphocytes of HD patients showed a significantly augmented activity of both G-6-PDH (P less than 0.001) and PHI (P less than 0.01), pointing to an increased HMPS and glycolytic activity. These findings are in support of an enhanced metabolic activity of both monocytes and lymphocytes in HD.

Sarcoidlike granulomas may occur in association with Hodgkin lymphoma and non-Hodgkin lymphoma. The granulomas may be concomitant and so extensive that they obscure the malignant process. In addition, a sarcoidosis-lymphoma syndrome has been described in which there appears to be a relationship between sarcoidosis and the development of a lymphoproliferative disorder. We report a case of a low-grade B-cell lymphoma with concomitant extensive sarcoidlike granulomas. The patient had no diagnostic clinical evidence of sarcoidosis, although she had an elevated serum calcium level and increased serum angiotensin converting enzyme activity. Increased serum calcium and serum angiotensin-converting enzyme activity have been associated with clinical sarcoidosis but have also occasionally been described in association with Hodgkin lymphoma and non-Hodgkin lymphoma without evidence of sarcoidosis. We describe our findings and illustrate the usefulness of immunoperoxidase immunophenotyping techniques in such a case.

A 77-year-old man was admitted to a hospital because of a left cervical tumor. He was initially diagnosed as having non-Hodgkin lymphoma, diffuse large cell type, Ann Arbor stage IV, and transferred to our hospital for chemotherapy. Flow cytometric analysis of the left axillary lymph node cells derived from a biopsy specimen showed that in addition to lymphoid surface markers (CD5, 7, 21), myeloid surface markers (CD11b, 33, 34) were also positive. The diagnosis of malignant lymphoma was therefore confirmed. The patient, was treated with THP-COP therapy, which proved very effective. Thereafter, a biopsy specimen was found to be positive for MT1 (CD43) staining but negative for myeloperoxidase and chloroacetate esterase staining on immunohistochemistry. Furthermore, no rearrangement of the IgH JH, TCR C beta 1 or TCR J gamma gene was detected by Southern blot analysis. On basis of these findings and the previous results of flow cytometry, we changed the diagnosis from malignant lymphoma to granulocytic sarcoma. THP-COP therapy was continued, and complete remission was achieved. Two months later, however, the patient developed acute myelocytic leukemia (AML M1) and received DCP therapy, but he died of pneumonia.

Reactivation of hepatitis is one of the most serious complications of chemotherapy in lymphoma patients who are carriers of the hepatitis B virus (HBV). Glucocorticoids are linked to increased risk of HBV reactivation. This study seeks to clarify whether removal of glucocorticoids from chemotherapy regimens may decrease the risk of HBV reactivation. Eligible patients were seropositive for hepatitis B surface antigen (HBsAg) and had histologically proven non-Hodgkin's lymphomas for which intensive chemotherapy was indicated. Patients were randomized to receive either ACE (epirubicin, cyclophosphamide, and etoposide) or PACE (prednisolone + ACE). A total of 50 patients were enrolled, 25 each for the ACE and PACE arms. The cumulative incidence of HBV reactivation at 9 months after starting chemotherapy was 38% and 73% for ACE and PACE arm, respectively (P =.03). The degree of clinical hepatitis was significantly more severe in the PACE arm: 11 patients (44%) in the PACE and 3 patients (13%) in the ACE arm had ALT elevation more than 10-fold of normal (P =.025), and 7 patients (28%) in the PACE and 1 patient (4%) in the ACE arm had icteric hepatitis (P =.049). Complete remission of tumors occurred in 11 (46%) patients in the PACE and 8 (35%) patients in the ACE arm (P =.556). The estimated overall survival rate at 46 months was 68% in the PACE arm and 36% in the ACE arm, respectively (P =.18). In conclusion, steroid-free chemotherapy decreases the incidence and severity of HBV reactivation in HBsAg-positive lymphoma patients. However, further research is needed to evaluate whether steroid-free chemotherapy may confer a less satisfactory control of lymphoma.

Paraneoplastic glomerulopathies are rare manifestations of neoplastic disease to be distinguished from iatrogenic renal damage. Solid tumors are preferentially associated with membranous nephropathy, whereas Hodgkin's lymphomas are associated with minimal change disease. The most common neoplasia associated with paraneoplastic glomerular disease are carcinomas of the lung and of the gastrointestinal tract. Nephrotic syndrome is the most frequent presentation of paraneoplastic glomerulopathy and the most critical glomerular disease regarding prognosis and patient care. Renal biopsy is recommended in patients with glomerular proteinuria or nephrotic syndrome and cancer, depending on life expectancy and therapeutic options. The primary treatment must be directed at the cancer in all cases. Symptomatic treatment of the nephrotic syndrome with diuretics and ACE inhibitors is justified. Prevention of nephrotic syndrome complications, i.e. thromboses and infections, should also be addressed and systematic regular renal follow-up is warranted. All treatments should be regularly reviewed to avoid toxicity, associated renal function loss or low albumin levels for patients receiving albumin-binding drugs. Epidemiologic studies have low evidence-based value. There is no widely accepted experimental model of the association of glomerulopathy and cancer. Thus, epidemiologic and mechanistic studies are needed to determine the true prevalence of paraneoplastic glomerulopathies and investigate new pathophysiologic approaches.
