Introduction: Hypophosphatasia (HPP) presents with defective bone mineralisation secondary to a deficit of non-tissue-specific alkaline phosphatase, increasing the risk of bone fracture. Sarcopenia may increase this risk. Therefore, rapid diagnosis with accessible and cost-effective tools such as ultrasound could be useful in clinical practice. The aim was to assess the correlation of ultrasound with another validated muscle mass assessment technique.

Material and Methods: Cross-sectional study in adults with PPH. Demographic (age, sex), analytical (alkaline phosphatase-AP) and clinical variables were collected (fractures, muscle strength measured with Jamar dynamometer in kilograms (kg) -cut-off point: <p10 of Spanish population-, rectus femoris quadriceps muscle mass with ultrasound -Sonosite S-Nerve®-, fat-free mass (FFM) in kg, fat mass and bone mineral density (according to T and Z-score) by dual-energy X-ray absorptiometry (DXA). Statistical analysis was performed with IBM SPSS v.25.

Results: Thirty-three subjects were studied, 55% women aged 49±18 years and mean FA: 29±11. 52% had at least one bone fracture and 67% had dental pathology. Low muscle strength was detected in 24% (62.5% men). Mean Y-axis was 1.4±0.7, mean circumference 9±2 and mean area 4.4±2. Mean FFM was 46.5±13.5. Muscle strength was positively correlated with Y-axis (r=0.42, P=0.02), with muscle area (r=0.4, P=0.02), with T-score in femoral neck (r=0.48, P=0.01) and in lumbar spine (r=0.66, P<0.001). Pressor strength in women was associated with BMI and FFM (P=0.004). It also showed a tendency to be associated with ultrasound muscle circumference (P=0.09). Muscle area correlated positively with FFM (r=0.52, P=0.01) and negatively with fat (r=- 0.37 P=0.03).

Conclusions: Ultrasound assessment was associated with body composition and muscle function parameters. Given its accessibility, ultrasound is a useful tool to assess muscle in PPH patients, allowing an early approach to reduce the risk of osteosarcopenia.
