Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Multicentric osteolysis, nodulosis and arthropathy (MONA) spectrum disorder is a rare inherited progressive skeletal disorder caused by mutations in the matrix metalloproteinase 2 (MMP2) gene. Treatment options are limited. The investigators reviewed the outcome of patients affected with MONA and treated with intravenous bisphosphonates in the clinical Center.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Assessment of the patients:

After informed consent had been obtained from the patients affected from MONA spectrum disorder the investigators assessed the patients regarding the following characteristics: consanguinity, clinical symptoms at diseases on-set, age at on-set of symptoms and age at diagnosis, cognitive development, progression of clinical symptoms related to the diagnosis, molecular investigations, associated disorders as well as therapies besides bisphosphonate therapy. Informed consent from the patients was also obtained to publish the patient's photographs. All investigations are performed according to the relevant ethical guidelines.

Bisphosphonate therapy:

The reported patients received intravenous bisphosphonate therapy either with pamidronate (1 mg/kg/d on two consecutive days every 3 months) or zoledronate (a single dose of 0.05 mg/kg/day every 6 month).

Evaluation of disease progression and therapeutic success:

To assess both progression of MONA spectrum disorder and therapeutic success the patients were regularly evaluated clinically in 3 to 6 month intervals. Clinical evaluation comprised an internal, neurological and orthopaedic status as well as a general assessment of neurocognitive function. Additionally, need for oral analgesic therapy was documented. In irregular intervals, depending also on the clinical symptoms, x-rays of hand and feet were taken and a densitometry of the total body, lumbar spine and hip was performed.
