Unusual presentation of a patient with complement deficiency and immunoglobulin deficiency
Bibliographic record
Abstract
Background The complement system is a vital component of innate immunity. Deficiencies in any part of the complement pathway characteristically present with recurrent infections. C2 factor deficiency is the most common complement deficiency. The presentation can vary from being asymptomatic to developing recurrent infections. Thus empiric vaccinations have been recommended, despite the lack of substantial evidence to support this practice. Recently, Jonnson and colleagues revisited this controversial topic and demonstrated the importance of vaccinations in this patient population. They further established that C2 deficient patients can mount an immune response to vaccination, undergo class-switching and develop a ‘more efficient’ phagocytosis. C2 deficiency is inherited in an autosomal recessive pattern. Homozygotes generally present with increased severity of disease as compared to heterozygotes. Alper and colleagues state that 25% of C2-deficient homozygotes have increased susceptibility to severe bacterial infections. Furthermore, they found that these C2-deficient patients had significantly lower mean levels of IgG4 and IgA than those patients that did not demonstrate an increased susceptibility for recurrent infections.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
