I'm using Algorithm2e and want a loop with no intial condition and no ending condition. Using Algorithmic, this can be achieved with \Loop ... \EndLoop, but I cannot find a similar loop for Algorithm2e. How do I do this in Algorithm2e?

The following minimal example defines
\nosemic: remove printing of the end-of-line (EOL) character (typically;);\dosemic: reinstate printing of the EOL character;\pushline: indents line by1em(the typical indent); provided byalgorithm2eas\Indp;\popline: remove indent of\pushline(undent?); provided byalgorithm2eas\Indm

Since I am unfamiliar with your algorithm2e setup, I'm not sure how you would like to combine the four commands. As such, I've kept them separate for maximum (yet manual) usage.
You can create a do-while construct using the same technique that a repeat-until construct is generated. They both fall under what algorithm2e calls "Repeat macros":
\SetKwRepeat{Do}{do}{while}
The above now allows you to use
\Do{<end condition>}{<stuff>}
Here is a minimal example showing its use/output:
\documentclass{article}
\usepackage[linesnumbered, ruled]{algorithm2e}
\SetKwRepeat{Do}{do}{while}%
\begin{document}
\begin{algorithm}[H]
\KwData{this text}
\KwResult{how to write algorithm with \LaTeX2e }
initialization\;
\While{not at end of this document}{
read current\;
\Repeat{this end condition}{
do these things\;
}
\eIf{understand}{
go to next section\;
current section becomes this one\;
}{
go back to the beginning of current section\;
}
\Do{this end condition}{
do these things\;
}
}

Something like this, with empty condition?
