Abstract
Hepatitis C-associated osteosclerosis (HCAO) is a very rare condition that can be observed in a small number of patients with Hepatitis C Virus (HCV) infection. HCAO is usually characterized by widespread bone sclerosis, associated with severe bone pain, and increased levels of bone turnover markers, especially alkaline phosphatase (ALP). In this report, we present the case of a 55-year-old woman who was affected by HCV and came to our attention for severe and diffuse bone pain. Radiological studies showed bone sclerosis, and bone mineral density (BMD) was markedly increased, as well as serum ALP levels. The patient was initially treated with intravenous pamidronate, which provided only a transient benefit on clinical symptoms. Then antiviral therapy for HCV (interferon-alfa and ribavirin) was started and it was effective in making the viral load undetectable. After a long follow-up period, we observed a persistent remission of bone pain, a reduction in BMD together with a progressive trend toward the normalization of bone turnover markers. In conclusion, HCAO, although rare, should be considered among the potential causes of increased bone mass in patients with HCV infection, and treatment for the underlying infection may be effective in controlling the manifestations of this disease.

Hepatitis C-Associated Osteosclerosis: Improvement After Treatment with Sofosbuvir, Daclatasvir, and Ibandronate: Case Report and Literature Review. Calcif Tissue Int 2021; 109:104-109.

Abstract
Hepatitis C-associated osteosclerosis (HCAO) remains a rare condition despite the growing prevalence of hepatitis C virus (HCV) infection worldwide. Since the first case reported in 1992, this is the twenty-second case described. Patients with HCAO present with severe bone pain and elevated serum levels of bone markers, especially alkaline phosphatase (ALP), with increased bone density. We report here the case of a 59-year-old man with generalized bone pain and diagnosis of HCV infection. Biochemical tests showed elevated bone turnover markers, specifically, ALP, carboxy-terminal collagen crosslinks and osteocalcin. Imaging studies revealed generalized bone sclerosis. Bone mineral density was elevated in all validated sites. His clinical symptoms and bone-related findings were attributed to HCAO. He was sequentially treated with cholecalciferol, prednisone, sofosbuvir associated with daclatasvir and ibandronate, and progressed with undetectable viral load after HCV treatment, normalization of ALP levels after introduction of ibandronate, and pain improvement 1 year after discontinuation of the bisphosphonate. Bone pain complaints must be investigated in patients with HCV. HCAO is a differential diagnosis of increased bone mass.

Abstract
Hepatitis C-associated osteosclerosis (HCAO), a very rare disorder in which an extremely rapid bone turnover occurs and results in osteosclerosis, was acknowledged in 1990s as a new clinical entity with the unique bone disorder and definite link to chronic type C hepatitis, although the pathogenesis still remains unknown. Affected patients suffer from excruciating deep bone pains. We report the 19th case of HCAO with diagnosis confirmed by bone biopsy, and treated initially with a bisphosphonate, next with corticosteroids and finally with direct acting antivirals (DAA: sofosbuvir and ribavirin) for HCV infection. Risedronate, 17.5 mg/day for 38 days, did not improve the patient’s symptoms or extremely elevated levels of bone markers, which indicated hyper-bone-formation and coexisting hyper-bone-resorption in the patient. Next, intravenous methylprednisolone pulse therapy followed by high-dose oral administration of prednisolone evidently improved them. DAA therapy initiated after steroid therapy successfully achieved sustained virological response, but no additional therapeutic effect on them was observed. Our results strongly suggested that the underlying immunological alteration is the crucial key to clarify the pathogenesis of HCAO. Bone mineral density of lumbar vertebrae of the patient was increased by 14% in four-month period of observation. Clarification of the mechanisms that develop osteosclerosis in HCAO might lead to a new therapeutic perspective for osteoporosis.

Abstract
Hepatitis C-associated osteosclerosis (HCAO) is an uncommon condition characterized by increased bone density, skeletal pain and elevated bone formation markers. Since 1992, only 17 cases have been reported. We herein describe the case of a 61-year-old woman affected by severe pain involving the lower limbs. The laboratory data showed an elevated serum alkaline phosphatase level, and the patient was found to be seropositive for hepatitis C virus infection. In addition, an X-ray skeleton survey showed marked cortical thickening of both femurs and tibias, and a whole-body bone scan revealed an increased cortical radionuclide uptake in the involved bones. These findings were consistent with a diagnosis of HCAO. In this report, we discuss the patient's clinical course over 16 years and, for the first time, show a normalized radioisotope uptake on bone scanning 10 years after the diagnosis.

Abstract
Hepatitis C-associated osteosclerosis (HCAO) is a rare sclerosing bone condition characterized by debilitating, predominantly lower extremity bone pain, accelerated bone turnover, and a generalized increase in histologically normal trabecular and cortical bone tissue. Herein we report the clinical presentation and imaging results of the 19th case of HCAO. Clinicians, particularly those caring for a population at risk for HCV infection, should be aware of this uncommon condition. The etio-pathogenesis of HCAO remains obscure but may bear important lessons in bone biology that could lead to new treatment options for osteoporosis.

Abstract
A finding of high BMD on routine DXA scanning is not infrequent and most commonly reflects degenerative disease. However, BMD increases may also arise secondary to a range of underlying disorders affecting the skeleton. Although low BMD increases fracture risk, the converse may not hold for high BMD, since elevated BMD may occur in conditions where fracture risk is increased, unaffected or reduced. Here we outline a classification for the causes of raised BMD, based on identification of focal or generalized BMD changes, and discuss an approach to guide appropriate investigation by clinicians after careful interpretation of DXA scan findings within the context of the clinical history. We will also review the mild skeletal dysplasia associated with the currently unexplained high bone mass phenotype and discuss recent advances in osteoporosis therapies arising from improved understanding of rare inherited high BMD disorders.

Abstract
The hepatitis C virus (HCV) is both hepatotropic and lymphotropic, responsible for a great number of hepatic and extrahepatic immune-system disorders that comprise the so-called HCV syndrome. HCV-associated rheumatic diseases are characterized by frequent clinico-serological overlap; therefore, correct classification of individual patients is necessary before therapeutic decisions are made. This is particularly difficult to do, however, because of the coexistence of viral infection and complex autoimmune alterations. In this context, mixed cryoglobulinemia syndrome (MCs) represents the prototype of virus-related autoimmune-lymphoproliferative diseases. MCs can be treated at different levels by means of etiological treatment with antivirals (peg-interferon-alpha plus ribavirin) aimed at HCV eradication and/or pathogenetic/symptomatic treatments directed to both immune-system alterations and the vasculitic process (rituximab, cyclophosphamide, steroids, plasmapheresis, and so on). In clinical practice, the therapeutic strategy should be modulated according to severity/activity of the MCs and possibly tailored to each individual patient's conditions. Cryoglobulinemic skin ulcers may represent a therapeutic challenge, which should be managed by means of both local and systemic treatments. HCV-associated arthritis should be differentiated from the simple comorbidity of HCV infection and classical rheumatoid arthritis. It may be treated with low doses of steroids and/or hydroxychloroquine; the use of biologics (rituximab) may be considered in more severe cases. Primary Sjögren's syndrome is rarely associated with HCV infection, while sicca syndrome and myalgia are frequently detectable in hepatitis C patients, with or without cryoglobulinemic vasculitis. Other autoimmune rheumatic disorders (poly/dermatomyositis, polyarteritis nodosa, osteosclerosis, fibromyalgia, and so on) have been reported as potentially associated with HCV infection in patient populations from different countries, suggesting the role of genetic and/or environmental co-factors. The therapeutic approach to these disorders should be decided according to each individual patient's evaluation, including hepatic, virological, and immunological findings.
