Hepatitis C viral load does not predict disease outcome: going beyond numbers

The analysis of 58 patients with chronic hepatitis C without cirrhosis and treated with interferon-alpha demonstrated that hepatitis C viral (HCV) load does not correlate with the histological evolution of the disease (p = 0.6559 for architectural alterations and p = 0.6271 for the histological activity index). Therefore, the use of viral RNA quantification as an evolutive predictor or determinant of the severity of hepatitis C is incorrect and of relative value. A review of the literature provided fundamental and interdependent HCV (genotype, heterogeneity and mutants, specific proteins), host (sex, age, weight, etc) and treatment variables (dosage, time of treatment, type of interferon) within the broader context of viral kinetics, interferon-mediated immunological response (in addition to natural immunity against HCV) and the role of interferon as a modulator of fibrogenesis. Therefore, viral load implies much more than numbers and the correct interpretation of these data should consider a broader context depending on multiple factors that are more complex than the simple value obtained upon quantification.

ABNORMAL SPERMATHECAE NUMBERS IN PERUVIAN SANDFLIES (DIPTERA: PSYSCHODIDAE)

We report and illustrate two abnormal spermatheca numbers found in Peruvian sandflies, a supernumerary spermatheca in Lutzomyia cernerai and the absence of one spermatheca in L. amazonensis.

Correlation of intra- and extraepidermal CD8 T cell numbers with development of psoriatic epidermal pathology

The development of psoriatic plaques is T cell dependent. Recently, Th17 CD4 T cells have been proposed to be the main effector cells. However, development of psoriasis is critically dependent on accumulation of epidermal T cells, among the majority express CD8. Here we show that numbers of epidermal CD8 T cells correlated with development of psoriasis in human biopsies, and that blockade of CD8 T cells by depleting antibodies inhibited development of psoriasis in the AGR xenotransplantation mouse model. In human dermis, both CD4 and CD8 T cell numbers correlated significantly with epidermal pathology, indicating a role for dermal CD4 T cells in orchestrating the development of psoriasiform changes induced by epidermis-infiltrating CD8 T cells.
