Peripheral blood cholyglycine and procollagen-III-peptide were measured in 22 Zairean patients with hepatomegaly caused by S. mansoni before and after treatment with praziquantel. Circulating T-cell subsets and cutaneous in vivo delayed type hypersensitivity were assessed; serum neopterin and beta 2-microglobulin served as indicators for macrophage/lymphocyte activation. The results were compared to age and sex matched patients with S. mansoni infection limited to the intestinal tract and schistosomiasis free controls with equal socioeconomic background. Abnormal serum cholyglycine and neopterin levels and alterations of circulating T-cell subset frequencies were associated with hepatomegaly in schistosomiasis. Normalization of these parameters reflected a regression of egg-induced immunopathology as early as two months after specific chemotherapy. Serum procollagen-III-peptide concentrations rose significantly after treatment, suggesting release of propeptide previously incorporated without cleavage into tissue collagen. The combination of these biochemical and immunological parameters may allow assessment of the pathophysiological mechanisms responsible for liver disease in individual patients.

In 20 patients with hepatic or hepatosplenic schistosomiasis and 82 individuals infected with S. mansoni, but without liver enlargement, serum parameters reflecting the fibrotic process and hemodynamic alterations as well as immunomodulation were examined. Included as controls were 35 age- and sex-matched healthy individuals from the study region in Northeast Brazil. Peripheral blood cholylglycine levels in patients with hepatomegaly, reflecting the spillover of portal blood into the systemic circulation, were elevated 12-fold over values of patients without liver involvement. Procollagen-III-peptide, a cleavage product of collagen synthesis, was elevated in patients with hepatomegaly (P less than 0.001) but normal in uncomplicated cases. Immunomodulation was assessed by in vivo delayed hypersensitivity to recall antigens and by serum beta 2-microglobulin and neopterin, substances released in the context of lymphocyte activation. Neopterin, predominantly a macrophage product, was elevated most strikingly in hepatomegalic cases (P less than 0.001). The possible interrelation between altered immune responses and excess fibrogenesis is discussed.

Eighty-one patients with non-Hodgkin's lymphoma had serum beta 2-microglobulin (beta 2M) estimated at presentation. A significant association was found between beta 2M levels and stage of disease (P less than 0.001), presence of hepatomegaly (P less than 0.001) and bone marrow involvement (P less than 0.05). No association was found between the level of beta 2M and histological group, presence of splenomegaly, lymph-node masses greater than 5 cm in diameter, lymphocyte count or the presence of systemic B symptoms. Pretreatment levels of beta 2M did not help predict response to treatment and achievement of a complete remission, the length of remission obtained or survival.

The serum levels of soluble intercellular adhesion molecule 1 (ICAM-1) were significantly elevated (P < .001) in patients with chronic B-lymphocytic leukemia (B-CLL, n = 113) compared with healthy controls (n = 31). sICAM-1 levels in B-CLL were positively correlated to the tumor mass as reflected by the modified Rai and the Binet staging systems, lymphocyte counts, and isolated spleno/hepatomegaly. During disease progression or regression on cytoreductive therapy, the circulating sICAM-1 levels changed accordingly. sICAM-1 was also correlated to a kinetic parameter such as the lymphocyte doubling time. Furthermore, the serum sICAM-1 levels were inversely correlated to hemoglobin levels in patients with early clinical stage, and this may turn out to be of prognostic value. sICAM-1 was compared with other serum markers said to reflect disease activity in B-CLL, ie, soluble CD23, thymidine kinase, lactate dehydrogenase (LDH), and beta 2-microglobulin. sICAM-1 was equally well or better correlated to clinical stage and lymphocyte doubling time. In univariate regression analysis, all serum markers but LDH correlated with survival, and in multivariate analysis, sICAM-1 was the only marker approaching significance for additional prognostic information when included after clinical stage and lymphocyte doubling time. Based on the present observations, it appears that prospective studies repeatedly monitoring serum sICAM-1 in B-CLL are justified.

In a prospective study, we investigated whether human immunodeficiency virus (HIV) infection alters the clinical presentation in patients with tuberculous pleuritis. One hundred twelve of 118 patients who presented with pleural effusion suffered from tuberculosis (TB); 65 patients (58%) were HIV seropositive. Evidence of disseminated TB was found more often in HIV-positive than in HIV-negative patients (30.8% vs 10.6%, p < 0.02). Dyspnea, fever, night sweat, fatigue, and diarrhea, severe tachypnea, hepatomegaly, splenomegaly, and lymphadenopathy were significantly more common in HIV-infected than in HIV-negative patients with TB. The same applied to a negative Mantoux reaction, lower hemoglobin, higher beta 2-microglobulin values, and in pleural fluid, lower albumin and higher gamma-globulin levels. Among HIV-infected patients, PPD skin test anergy was significantly associated with relative low albumin and gamma-globulin levels of pleural fluid. However, the radiographic features did not differ with respect to HIV status; they were predominantly those of primary pleuritis (78% in each group). We conclude that coexisting HIV infection affects clinical and laboratory features, but not the radiographic presentation of patients with TB pleuritis in Tanzania.
