Cyclosporin A treatment and decreased fungal load/antigenemia in experimental murine paracoccidioidomycosis.
Article in Mycopathologia, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the fungus Paracoccidioides brasiliensis (Pb). The cyclosporin A (CsA) is an immunosuppressant drug that inhibits calcineurin and has been described as a potential antifungal drug. The present study investigated the effect of CsA on the immune response, fungal load/antigenemia in experimental murine PCM. It was used four groups of BALB/c mice: (a) infected with 1 x 10⁵ Pb18 yeast cells (Pb), (b) infected and treated with CsA every other day 10 mg/kg of CsA (s.c.) during 30 days (Pb/CsA), (c) treated with CsA (CsA) and (d) no infected/treated (PBS). The immune response was evaluated by lymphocyte proliferation, DTH assays to exoAgs, ELISA for IgG anti-gp43 (specific immune responses) and cytokine serum levels (IFN-γ, TNF-α, IL-4 and IL-10). Fungal load was determined by lung colony-forming units (CFU) counts, lung and liver histopathology analysis and antigenemia determined by inhibition-ELISA. As expected, CsA was able to inhibit the specific cellular and humoral immune response (P < 0.05), with decrease in serum IFN-γ, TNF-α and IL-4 levels (P < 0.05). Cyclosporin A treatment also resulted in significantly decreased lung Pb CFU (P < 0.05) as well as a lower number of yeasts in the lung and liver (P < 0.05) by histopathology. In concordance, the decreased antigenemia was observed in Pb/CsA group (P < 0.05). In conclusion, even with immunosuppressive action, treatment with CsA results in decreased lung fungal load/antigenemia in experimental PCM in BALB/c mice. Further study is required to determine whether this represents less severe disease or protection by CsA.
