Bone is a vibrant tissue comprising of osteoblasts and osteoclasts. Osteoblasts synthesise bone matrix, whereas osteoclasts help in bone resorption. Osteopetrosis is a heritable disorder that leads to failure of osteoclasts to resorb bone. This leads to impairment in bone modelling and remodelling as changes occur in the shape and structure of the bone. Nearly 70% of osteopetrosis is caused by genetic mutations of TCIRG1, CLCN7, OSTM1, RANKL, RANK and PLEKHM1 genes. Clinical manifestations range from increased bone density, skeletal fragility, disturbed tooth eruptions to haematopoietic insufficiency, nervous degeneration, mental retardation and developmental delay. Diagnosis is mainly by clinical presentation and radiological findings. Treatment is primarily supportive to stimulate host osteoclasts by administering calcium and Vitamin D supplementation, high-dose calcitriol, joint arthroplasty, interferon gamma 1b and gene therapy. Haematopoietic stem cell transplantation is indicated for severe forms of autosomal recessive osteopetrosis. Infantile and intermediate forms of autosomal recessive osteopetrosis can be fatal if left untreated. This article includes a case report of osteopetrosis with focused nursing care using nursing process approach.

| Introduction | |  |
Osteopetrosis is derived from a Greek word, where 'osteo' refers to bone and 'petros' refers to stone, 'stone bone'. It is also known as marble bone disease and Albers-Schonberg disease, first described by a German radiologist Albers-Schonberg in 1904. He identified the radiographic findings in a patient with increased bone density. Osteopetrosis is a heterogeneous group of heritable condition characterised by the failure of osteoclasts' function, leading to increased bone density.[1] Osteoclasts are multinucleated cells of haematopoietic lineage that are vital for bone remodelling. Osteoblasts are mesenchymal in origin. The bone matrix synthesised by the osteoblasts supports the growth, maturation and function of osteoclasts. They also secrete macrophage colony-stimulating factor (CSF), granulocyte macrophage-CSF, interleukin-1 and interleukin-6, which influence the osteoclast's activity. Bone density is based on the relative functioning of these two cell types.[2],[3]
| Incidence | | |
Severe autosomal recessive form of osteopetrosis has an incidence of approximately 1 in 250,000 births and a mild autosomal dominant form has an incidence of 1 in 20,000 births.[4]
| Classification | | |
In humans, there are three forms of osteopetrosis based on age and clinical factors:[2]
- Infantile: Featured by autosomal recessive inheritance with severe bone marrow failure. It is usually diagnosed before 1 year of age
- Intermediate: Has autosomal recessive inheritance with no bone marrow failure symptoms
- Adult onset: The inheritance is autosomal dominant without bone marrow failure. It is often detected incidentally.
Autosomal recessive, autosomal dominant and X linked recessive forms exist, with the most severe form being the autosomal recessive type.[5]
| Prognosis | | |
The adult-onset osteopetrosis has good prognosis unlike the infantile and intermediate forms, which can be fatal if left untreated. However, the disease is heterogeneous in clinical presentation and often misdiagnosed.[5]
| Aetiology and Pathophysiology | | |
Osteoclastic failure
Osteopetrosis is caused by defect in the formation, differentiation and functioning of osteoclasts. This leads to failure in bone resorption. The defect may lie in the osteoclast lineage itself or in the mesenchymal cells that form and maintain the microenvironment required for proper osteoclast function.[1]
Genetic defects/mutations
Recently, the heterogeneous molecular or genetic defects that impair osteoclastic function have been studied and largely uncovered. Mutations in at least ten genes have been identified as causative in humans, accounting for 70% of all cases of osteopetrosis. Intrinsic disturbances of osteoclastic function due to mutations in genes encoding osteoclast-specific subunits of the vacuolar proton pump (TCIRG1, CLCN7, OSTM1, RANKL, RANK and PLEKHM1) are found in most patients with recessive form. Mutations in TNFSF11 and TNFRSF11A lead to osteoclast-poor ARO. Mutations of CLCN7 are observed in the dominant form of osteopetrosis.[4],[5]
Carbonic anhydrase isoenzyme II deficiency
Deficiency of carbonic anhydrase isoenzyme II (CA II) has been identified as the primary defect in the autosomal recessive syndrome of osteopetrosis with renal tubular acidosis and cerebral calcification. Lack of CAII results in impaired bone resorption. This enzyme catalyses the formation of carbonic acid from water and carbon dioxide. Carbonic acid dissociates spontaneously to release protons, which are essential for creating an acidic environment required for dissolution of bone mineral in the resorption lacunae.[2]
Viruses
Virus-like inclusions have been reported in osteoclasts of some patients with benign osteopetrosis, but the clinical significance remains uncertain.[2]
Absence of colony-stimulating factor-1
Absence of biologically active CSF-1 due to a mutation in its coding gene caused impairment of osteoclastic function in osteopetrotic mouse.[2]
Osteoblastic function
Recent research has shown that osteoblasts can predispose the disease due to their intrinsic defects or because their activity may be enhanced by deregulated osteoclasts abundantly present in most forms.[2]
| Clinical Manifestations | | |
The manifestations are grossly heterogeneous ranging from asymptomatic to fatal in infancy.[1],[4] The more severe forms tend to have autosomal recessive inheritance, whereas the mildest forms are observed in adults and are inherited in an autosomal dominant manner.
- Skeletal: Increased bone density, diffuse and focal sclerosis of varying severity, modelling defects at metaphyses, pathological fractures and osteomyelitis
- Dental: Tooth eruption defects and dental caries
- Haematological: Haematopoietic failure leading to pancytopenia, extramedullary haematopoiesis and hepatosplenomegaly
- Neurological: Neurodegeneration including retinal atrophy, cranial nerve compression (II, VII, VIII-optic nerve, blindness, auditory nerve, deafness, facial nerve and paresis), hydrocephalus, intracranial calcification, convulsions, mental retardation
- Others: Hypocalcaemia, renal tubular acidosis, developmental delay, lymphedema and immunodeficiency, resulting in overwhelming infection.
| Diagnosis | | |
The disease is mainly diagnosed based on the clinical features and radiological findings of the skeleton.
Radiological testing
Computed tomographic scans, magnetic resonance imaging and bone scans provide specific information.
Classic radiological features of osteopetrosis
Radiologic features of osteopetrosis usually provide the specific diagnosis. Bones may show generalised osteosclerosis, evidence of fractures or osteomyelitis and may be uniformly sclerotic affecting the skull, spine, pelvis and appendicular bone.[2] Bone modelling defects at the metaphyses of long bones, such as funnel-like appearance ('Erlenmeyer flask' deformity), characteristic lucent bands, 'bone within a bone' or endobone phenomena (tarsals, carpals, phalanges, vertebra and ilium) and thickened growth plates if there is superimposed rickets and presence of 'Sandwich' vertebrae and 'Rugger-jersey' spine are typical of this disease.[1]
Genetic testing
Genetic testing can be used to confirm the diagnosis, differentiate between different subtypes of osteopetrosis and predict the prognosis.
Biopsy
Iliac crest bone biopsy is used to quantitate osteoclast and marrow changes by light and electron microscopy. It can distinguish between osteoclast-poor and osteoclast-rich subtypes of autosomal recessive osteopetrosis.
Creatine kinase BB isoenzyme and tartrate-resistant acid phosphatase
Raised concentrations of the creatine kinase BB isoenzyme and tartrate-resistant acid phosphatase are noted in autosomal dominant forms.[2]
Differential diagnosis
According to Stark and Savarirayan,[1] some of the alternative diagnoses to consider include:
- Fluorosis
- Beryllium, lead and bismuth poisoning
- Myelofibrosis
- Paget's disease (sclerosing form)
- Malignancies (lymphoma, osteoblastic cancer metastases).
| Genetic Counselling | | |
Genetic counselling is based on the mode of inheritance in a particular family. The following factors can be considered and discussed with the family:
- Autosomal recessive: The parents of the affected child have a 1 in 4 (25%) risk of having further affected children in each pregnancy. Around 2/3rd of the unaffected siblings are expected to be carriers
- Autosomal dominant: Each child of an affected individual has a 1 in 2 (50%) risk of being affected
- X-linked recessive: If the mother of the child is a carrier, 50% of male pregnancies will be affected, and 50% of female pregnancies will be carriers.[1]
| Treatment | | |
At present, there is no successful medical treatment available for osteopetrosis. Thus, the treatment is mainly supportive aimed at providing multidisciplinary surveillance and symptomatic management of complications (Stark and Savarirayan, 2009). Medical treatment of osteopetrosis is based on efforts to stimulate host osteoclasts or provide an alternative source of osteoclasts.
Osteoclastic stimulators
Stimulation of host osteoclastic differentiation has been attempted with calcium restriction, high-dose calcitriol, steroids, parathyroid hormone and interferon (IFN).[4],[6]
Symptomatic management
- Prevention and management of fractures and arthritis due to bone brittleness
- Calcium and Vitamin D supplementation for hypocalcaemic seizures
- Red blood cell and platelet transfusions for bone marrow failure
- Monitoring for developmental delay through neurological evaluation
- Ophthalmologic surveillance to detect optic nerve atrophy
- Dental surveillance and maintenance of oral hygiene to prevent and manage delayed tooth eruption, ankylosis, abscesses, cysts and fistulas.
Surgery
Corrective osteotomies are performed in children for non-union of a fractured femoral neck and for coxa vara.[7] Open reduction and internal fixation with intramedullary fixation of fractures is difficult but possible due to hardness of bone. Total hip and total knee arthroplasties have excellent results.[8] Surgical decompression of optic nerve to prevent vision loss is also been carried out.[1]
Gene therapy
Recent trials on haematopoietic stem cell-targeted gene therapy in a mouse model of infantile malignant osteopetrosis was shown to correct many aspects of the disease.[9]
Haematopoietic stem cell transplantation
Haematopoietic stem cell transplantation (HSCT) is indicated for severe forms of autosomal recessive osteopetrosis. HSCT using human leucocyte antigen-identical donors resulted in 73% 5-year disease-free survival. The only curative treatment for malignant infantile osteopetrosis is stem cell transplantation to provide monocytic osteoclast precursors. The complications include rejection, delayed haematopoietic reconstitution, venous occlusive disease, pulmonary hypertension and hypercalcaemic crisis. Outcomes are better with early transplantation, particularly before the age of 3 months.[1],[4],[6]
Interferon gamma 1b
IFN gamma 1b is found to improve the immune system, increase bone resorption and increase bone marrow space. This therapy is indicated in patients with osteopetrosis variants unlikely to respond to HSCT and also as a bridge to transplantation.[1]
| Complications | | |
Failure of the osteoclasts to resorb the bone leads to complications such as thickened, dense, deformed and easily fractured bone.[10] Delayed union or non-union of fractures and osteomyelitis especially of the mandible may occur.[1] Other complications include growth failure, anaemia, hypoplastic dentition, chronic infections, facial fistulas, blindness, hearing loss, nasal congestion, upper airway obstruction and neurodegeneration.[11]
| Nursing Management of a Child With Osteopetrosis | | |
Nursing management in osteopetrosis is discussed using a case report and nursing process approach.[12]
Case report
One-year-old Master S. was referred to a tertiary care hospital in view of suspected osteopetrosis. He is the third child of a consanguineous marriage. He had an older sibling who expired at 18 months of age due to autosomal recessive osteopetrosis. Hence, Master S. was empirically evaluated at a local hospital at 6 months of age and was found to have radiological features of osteopetrosis. On physical examination, he was found to have short neck, short nose, dysplastic pinna, frontal bossing of skull, periorbital puffiness, sparse eyebrows, soft non-tender palpable liver –5 cm below the costal margin and stunted growth. He was confirmed to have autosomal recessive osteopetrosis on the basis of bone marrow biopsy, which showed thickened bone trabeculae with interconnected woven bone surrounding unresorbed cartilage with hypercellular marrow. Definite osteoclasts were not seen. Mutation analysis had no pathological variants on TC1RG1, CLCN7, OSTM1 and RANK genes. Radiological findings showed hyperdense skeletal bones, prominence of frontal bone, thickened bony cortex, increased density of facial bones and narrowing of cranial nerve outlets.
He underwent haplo-identical stem cell transplantation, with his mother being the donor. A total dose of 12.8 × 106/kg CD 34+ cells was transfused. The dose of total nucleated cells infused was 13.13 × 108/kg. Post transplantation, he developed febrile neutropenia and lower respiratory tract infection related to Adeno virus. Chest X-ray revealed right-sided opacity. Throat swab (multiplex polymerase chain reaction [PCR] for respiratory virus) showed adeno virus, rhino virus and Cytomegalovirus (CMV). PCR showed an increased viral load of 5281 copies/ml suggesting ganciclovir-resistant CMV strains. Blood culture revealed vancomycin-resistant Enterococcus and extended-spectrum beta-lactamase (ESBL) Escherichia coli. He also developed follicular erythematous skin rash over the thighs, back and perineum due to Engraftment syndrome. Skin biopsy revealed Grade III graft versus host disease (GVHD). He developed severe abdominal pain, loose stools and melena (10–12 episodes/day) from day +27 to day +42 post transplant. Rectal biopsy revealed evidence of Grade IV gastrointestinal (GI) GVHD. He also developed cyclosporine-induced microangiopathic haemolytic anaemia and hypertension, hypercalcaemia, viral conjunctivitis and rhino viral infection. He was on continuous oral immunosuppressive therapy, antimicrobial therapy, blood product support, granulocyte CSF, phototherapy and total parenteral nutrition. However, the child was stable at the time of discharge after being hospitalised for about 4 months.
The nursing assessment revealed the following needs/problems:
- Parental anxiety related to child's condition and treatment procedures, environmental adaptation
- Knowledge deficit related to therapy, home care
- Complications related to treatment (stem cell transplant)
- Septicaemia
- GVHD
- Skin rashes/engraftment syndrome
