Protocols for nutritional care and treatment of severely malnourished adult HIV/AIDS patients on ART

I have seen that some countries have included protocols for nutritional care and treatment of adult severely malnourished HIV/AIDS patients on ART in their national guidelines. And in some of them the treatment protocols are the same as those for children 6-59 months of age. But are there any international guidelines and research based evidence supporting the same protocols? Is there enough evidence or lack of evidence to support these protocols (the same protocols as that for children 6-59) for SAM management of Adult HIV/AIDS patients?
