201 Possible Causes for C2 Decreased

  • Angioedema

    Detailed laboratory investigations revealed decreased serum levels of several complement components, including C2, C4, C1q, and C1INH.[ncbi.nlm.nih.gov]

  • Hereditary Angioedema

    Hereditary angioedema (types 1 and 2) or acquired C1 inhibitor deficiency is confirmed by Low levels of C4 (and C2, if measured) Decreased C1 inhibitor function Other findings[msdmanuals.com] The C4 level is persistently low in most, but not all, patients, whereas the C2 level may remain decreased in a smaller proportion of patients.[archinte.ama-assn.org] In a few patients, C4 and C2 levels normalize in the absence of symptoms. 9, 24, 34 There is no correlation between the magnitude of decrease in C1-INH level or activity and[archinte.ama-assn.org]

  • Hereditary Angioedema Type 1

    Hereditary angioedema (types 1 and 2) or acquired C1 inhibitor deficiency is confirmed by Low levels of C4 (and C2, if measured) Decreased C1 inhibitor function Other findings[msdmanuals.com] Normal C1 level and decreased C4 level Normal C2 level and decreased C1 level Normal C3 level and decreased C1 level Normal C4 level and decreased C3 level 5.[mdmag.com]

  • Hereditary Angioedema Type 2

    Hereditary angioedema (types 1 and 2) or acquired C1 inhibitor deficiency is confirmed by Low levels of C4 (and C2, if measured) Decreased C1 inhibitor function Other findings[merckmanuals.com] Normal C1 level and decreased C4 level Normal C2 level and decreased C1 level Normal C3 level and decreased C1 level Normal C4 level and decreased C3 level 5.[mdmag.com]

  • Narrow Cervical Spinal Canal

    Radiographic features normal AP diameter is 17 mm relative stenosis 10-13 mm absolute stenosis The width of the canal is not, however, constant and progressively decreases[radiopaedia.org] C1: 23 mm C2: 20 mm C3-C6: 17 mm C7: 15 mm Canal-to-body ratio of Torg and Pavlov The standard method of evaluating cervical canal stenosis was historically the sagittal diameter[radiopaedia.org]

  • Polymyalgia Rheumatica

    (A2, B2, and C2) After treatment, FDG uptake decreased in these sites - bone marrow, from SUV max 4.02 (A1) to 2.50 (A2); spleen, from SUV max 6.05 (A1 and C1) to 4.38 (A2[arthritis-research.biomedcentral.com] […] and C2) - as well as in multiple lymph nodes, including in the axilla, mediastinum, hilar region of the lung, hilar region of the liver, and para-aortic region (B1/C1 B2[arthritis-research.biomedcentral.com]

  • Cervicogenic Headache

    If you apply a PA pressure on left C2, you will notice how it decreases stretch at C1/2 joint but increases the stretch at C2/3.[raynersmale.com] This will often involve using mobilisation or manipulation techniques particularly through the C1, C2 and C3 spinal segments.[kingsleyphysio.com] In left rotation and extension PA pressure on left C2 increases stretch at the C1/2 joint. PA pressure on left C1 decreases rotation at the C1/2 joint.[raynersmale.com]

  • Glaucoma

    Yeast two-hybrid analyses of a subset of the missense mutations within the C2 domains of RPGRIP1 shows that five of them (p.R598Q, p.A635G, p.T806I, p.A837G and p.I838V) decrease[doi.org] […] the association of the C2 domains with nephrocystin-4 (NPHPH).[doi.org]

  • Diabetes Mellitus Type 1

    However, a significant decrease (P 0.005) in CRS was found in diabetic children with sDAN [n 12; C2: 221.0 micromol/l (95% CI: 75.7-644.8 micromol/l)] compared with diabetic[ncbi.nlm.nih.gov] -134.2 micromol/l)] vs. healthy children--C2: 72.4 micromol/l (95% CI: 75.7-644.8 micromol/l)].[ncbi.nlm.nih.gov] We found that CRS in the whole group of diabetic children was not significantly different from that in healthy children [diabetic children--C2: 75.1 micromol/l (95% CI: 42.0[ncbi.nlm.nih.gov]
