The presence of cachectin or tumor necrosis factor (TNF) associated with hypertriglyceridemia was demonstrated in the serum of patients with pulmonary tuberculosis. The hyperlipidemia that accompanies this infection may be mediated by the TNF inhibition of lipoprotein lipase activity. This sequence of events may be sufficient to explain, in part, the complex metabolic changes and emaciation observed in tuberculosis patients.

The Leydig cell tumor has been reported to produce tumor necrosis factor (TNF) and induce cachexia in rats. TNF is thought to reduce lipoprotein lipase (LPL) activity, decrease fat deposits, induce emaciation, and worsen cachexia. Therefore, we thought emaciation might be prevented and thus cachexia improved by increasing LPL activity. We administered NO-1886, a lipoprotein lipase activator, to rats bearing Leydig cell tumor and observed its effect on improving the cachexia induced by the tumor. In Leydig cell tumor-bearing rats, the emaciation progressed after tumor inoculation and the general condition worsened daily. Plasma levels of total protein, albumin, and glucose, which are biological parameters of malnutrition, were found to decrease soon after tumor inoculation in tumor-bearing rats. In contrast, rats given NO-1886 showed less malnutrition than tumor-bearing rats. LPL activity of rat adipose tissue was decreased, the weight of adipose tissue was decreased, carcass weight was reduced, and food consumption was decreased after Leydig cell tumor inoculation. NO-1886 increased adipose tissue LPL activity and suppressed the decrease in the weight of adipose tissue, carcass weight, and food consumption due to cachexia without influencing tumor growth. The present results suggest that the novel compound NO-1886 may suppress carcass weight loss in rats bearing Leydig cell tumor by suppressing the decrease in food consumption and LPL activity.

Harbor porpoises from the North and Baltic Seas exhibit a higher incidence of bacterial infections compared to whales from less polluted arctic waters. Toxicological analysis revealed an association between elevated body burdens of environmental contaminants, such as polychlorinated biphenyls (PCB) and polybrominated diphenyl ether (PBDE) and lymphoid depletion in thymus and spleen of these whales. However, it remains undetermined if changes in the immune system are primarily contaminant-induced or a sequel of infectious diseases and emaciation. The aim of the present study was to investigate changes of blood cytokine mRNA levels in healthy and diseased harbor porpoises. Therefore, 29 by-caught and stranded whales were necropsied and the health status was evaluated based upon main pathological findings. Furthermore, the degree of thymic atrophy and splenic depletion was histologically graded using a semi-quantitative scoring system. Gene expression of interleukin (IL)-2, IL-4, IL-6, IL-10, transforming growth factor-beta and tumor necrosis factor-alpha in the blood was measured by real time reverse transcription-polymerase chain reaction. Thymic atrophy and splenic depletion were correlated with an impairment of the animals' health status. Additionally, a marked up-regulation of IL-10 was predominately found in severely diseased whales with evidence of chronic bacterial infections. Furthermore, increased IL-10 levels were associated with splenic depletion. Other investigated cytokines were not significantly associated with the health status or lymphoid depletion, respectively. The present study indicated that lymphoid depletion represents a sequel of chronic infectious diseases in a portion of investigated harbor porpoises. Regarding this, expression of anti-inflammatory cytokines, such as IL-10 might represent a consequence of continuous stimulation of the immune system and induction of immunomodulatory mechanisms in this cetacean species.
