Haploidentical α/β T-cell and B-cell depleted stem cell transplantation in severe mevalonate kinase deficiency. Rheumatology (Oxford) 2021; 60:4850-4854.

Abstract
OBJECTIVE Mevalonic aciduria represents the most severe form of mevalonate kinase deficiency (MKD). Patients with mevalonic aciduria have an incomplete response even to high doses of anti-cytokine drugs such as anakinra or canakinumab and stem cell transplantation (SCT) represents a possible therapy for this severe disease. METHODS We report the first two children affected by severe MKD who received haploidentical α/β T-cell and B-cell depleted SCT. Both patients received a treosulfan-based conditioning regimen and one received a second haploidentical-SCT for secondary rejection of the first. RESULTS Both patients obtained a stable full donor engraftment with a complete regression of clinical and biochemical inflammatory signs, without acute organ toxicity or acute and chronic GvHD. In both, the urinary excretion of mevalonic acid remained high post-transplant in the absence of any inflammatory signs. CONCLUSION Haploidentical α/β T-cell and B-cell depleted SCT represents a potential curative strategy in patients affected by MKD. The persistence of urinary excretion of mevalonic acid after SCT, probably related to the ubiquitous expression of MVK enzyme, suggests that these patients should be carefully monitored after SCT to exclude MKD clinical recurrence. Prophylaxis with anakinra in the acute phase after transplant could represent a safe and effective approach. Further biological studies are required to clarify the pathophysiology of inflammatory attacks in MKD in order to better define the therapeutic role of SCT.

Abstract
Genetic testing has become an integral component of the diagnostic evaluation of patients with suspected primary immunodeficiency diseases. Results of genetic testing can have a profound effect on clinical management decisions. Therefore clinical providers must demonstrate proficiency in interpreting genetic data. Because of the need for increased knowledge regarding this practice, the American Academy of Allergy, Asthma & Immunology Primary Immunodeficiency Diseases Committee established a work group that reviewed and summarized information concerning appropriate methods, tools, and resources for evaluating variants identified by genetic testing. Strengths and limitations of tests frequently ordered by clinicians were examined. Summary statements and tables were then developed to guide the interpretation process. Finally, the need for research and collaboration was emphasized. Greater understanding of these important concepts will improve the diagnosis and management of patients with suspected primary immunodeficiency diseases.
