TEMPI syndrome
Orphan disease
TEMPI syndrome is an orphan disease where the patients share five characteristics from which the acronym is derived: telangiectasias, elevated erythropoietin and erythrocytosis, monoclonal gammopathy, perinephric fluid collection, and intrapulmonary shunting.
| TEMPI syndrome | |
|---|---|
| Other names | Telangiectasia-erythrocytosis-monoclonal gammopathy-perinephric-fluid collections-intrapulmonary shunting syndrome |
| TEMPI | Symptom |
|---|---|
| T | Telangiectasias |
| E | Elevated Erythropoietin and Erythrocytosis |
| M | Monoclonal gammopathy |
| P | Perinephric fluid collections |
| I | Intrapulmonary shunting |
The patients were all diagnosed at middle age. A monoclonal gammopathy was implicated in all patients tested.[1]
The cause of the syndrome is unknown. The abnormal plasma-cell clone and/or the monoclonal gammopathy are suggested to be triggers of the disease.[2]
The diagnosis is based on the five characteristics described above.[2]
Complete and partial disappearance of the symptoms of the TEMPI syndrome was reported with the drugs bortezomib,[3] daratumumab[4] and autologous stem cell transplantation.[5]
In 2010, the case of a man with unexplained erythrocytosis and perinephric fluid collection as main features was described in the Case Records of the Massachusetts General Hospital.[6]
