Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,320 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

systemic inflammatory response syndrome (SIRS). This is most likely secondary to sepsis from an infection of the patient's Hickman catheter given the associated skin findings, although culture results are needed to confirm this diagnosis. The patient's low blood pressure is likely secondary to developing septic shock, and he has already appropriately been treated with intravenous fluids. Catheter removal is indicated given his hemodynamic instability. Catheter removal is also indicated in patients with severe sepsis with organ hypoperfusion, endocarditis, suppurative thrombophlebitis, or persistent bacteremia after 72 hours of appropriate antibiotic therapy. Long term catheters should also be removed if culture results are positive for S. aureus, P. aeruginosa, fungi, or mycobacteria.
