Analysis of Hand Joint Space Morphology in Women and Men with Hereditary Hemochromatosis. Calcif Tissue Int 2023; 112:440-451. [PMID: 36738308 PMCID: PMC10025180 DOI: 10.1007/s00223-022-01050-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 11/25/2022] [Indexed: 02/05/2023]
Abstract
Hereditary hemochromatosis (HH) causes unbalanced iron deposition in many organs including the joints leading to severe cartilage loss and bone damage in the metacarpophalangeal joints (MCPJ). High-resolution peripheral quantitative computed tomography (HR-pQCT) and its joint space width (JSW) quantification algorithm quantifies in vivo 3D joint morphology. We therefore aimed to (i) determine feasibility and performance of the JSW algorithm in HH, (ii) quantify joint space morphology, and (iii) investigate the relationship between morphological and clinical parameters in HH. Here, we performed an exploratory study on 24 HH patients and sex- and age-matched controls using HR-pQCT imaging of MCPJ. Mineralized bone structure was automatically segmented from the grayscale image data and periosteal surface bone masks and joint space masks were generated. Mean, minimal, and maximal joint space width (JSW; JSW.MIN; JSW.MAX), JSW heterogeneity (JSW.SD), JSW asymmetry (JSW.AS), and joint space volume (JSV) were computed. Demographics and, for HH patients, disease-specific parameters were recorded. Segmentation of JS was very good with 79.7% of MCPJs successfully segmented at first attempt and 20.3% requiring semi-manual correction. HH men showed larger JSV at all MCPs (+ 25.4% < JSV < + 41.8%, p < 0.05), larger JSW.MAX at MCP 3-4 (+ 14%, 0.006 < p < 0.062), and wider JSW (+ 13%, p = 0.043) at MCP 4 relative to HH women. Compared to controls, both HH men and HH women showed larger JSW.AS and smaller JSW.MIN at all MCP levels, reaching significance for HH men at MCP 2 and 3 (JSW.AS: + 323% < JSW.AS < + 359%, 0.020 < p < 0.043; JSW.MIN: - 216% < JSW.MIN < - 225%, p < 0.043), and for women at MCP 3 (JSW.AS: + 180%, p = 0.025; JSW.MIN: - 41.8%, p = 0.022). Time since HH diagnosis was correlated positively with MCP 4 JSW.AS and JSW.SD (0.463 < ρ < 0.499, p < 0.040), and the number of phlebotomies since diagnosis was correlated with JSW.SD at all MCPs (0.432 < ρ < 0.535, p < 0.050). HR-pQCT-based JSW quantification in MCPJ of HH patients is feasible, performs well even in narrow JS, and allows to define the microstructural joint burden of HH.

A Mystery of Joint Pain: Is It Rheumatoid Arthritis (RA) or Hereditary Hemochromatosis (HH)? Cureus 2022; 14:e33037. [PMID: 36721599 PMCID: PMC9881094 DOI: 10.7759/cureus.33037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/27/2022] [Indexed: 12/29/2022] Open
Abstract
A 58-year-old lady with a previous diagnosis of rheumatoid arthritis (RA) was referred to Rheumatology to manage her joint pains. On evaluation, it was noted that the lady did not have any signs of synovial inflammation. The patient had a negative anti-cyclic citrullinated peptide (anti-CCP) (<0.5) and negative rheumatoid factor (RF) (<10) together with high ferritin (1,507 µg/L) which led to consideration of hereditary hemochromatosis (HH) rather than RA. She was then referred to Hematology for regular venesection which settled her symptoms. This case report highlights the importance of considering HH as a differential diagnosis in patients with chronic arthritis particularly if there are no clinical signs and negative tests for RA. More retrospective studies will be needed to quantify how many cases of hemochromatosis arthropathy have been mistakenly diagnosed as RA.

Arthritis Prediction of Advanced Hepatic Fibrosis in HFE Hemochromatosis. Mayo Clin Proc 2022; 97:1649-1655. [PMID: 35422339 DOI: 10.1016/j.mayocp.2022.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 01/23/2022] [Accepted: 02/14/2022] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To evaluate whether arthritis predicts the likelihood of advanced hepatic fibrosis in HFE hemochromatosis. PATIENTS AND METHODS We conducted a retrospective, cross-sectional analysis of 112 well-characterized patients with HFE hemochromatosis and liver biopsy-validated fibrosis staging recruited between January 1, 1983, and December 31, 2013. Complete clinical, biochemical, hematologic, and noninvasive serum biochemical indices (aspartate aminotransferase to platelet ratio index [APRI] and fibrosis 4 index [FIB4]) were available. Scheuer fibrosis stages 3 and 4, APRI greater than 0.44, or FIB4 greater than 1.1 were used to define advanced hepatic fibrosis. Comparisons between groups were performed using categorical analysis, unpaired or paired t test. RESULTS Male (n=76) and female (n=36) patients were similar in age. Nineteen patients had advanced hepatic fibrosis, and 47 had hemochromatosis arthritis. Arthritis was significantly associated with the presence of advanced hepatic fibrosis as determined by liver biopsy (sensitivity, 84%, [95% CI, 62% to 95%]; negative predictive value, 95% [95% CI, 87% to 99%]; relative risk, 7.4 [95% CI, 2.5 to 23]; P<.001), APRI (sensitivity, 75% [95% CI, 55% to 88%]; negative predictive value, 91% [95% CI, 81% to 96%]; relative risk, 4.5 [95% CI, 2.0 to 10.2]; P<.001), or FIB4 (sensitivity, 61% [95% CI, 41% to 78%]; negative predictive value, 67% [95% CI, 68% to 90%]; relative risk, 2.2 [95% CI, 1.1 to 4.6]; P=.03). Mean cell volume values were significantly higher pretreatment in patients with F3-4 fibrosis (96.7±1.1 fL) compared with F0-2 fibrosis (93.4±0.5 fL; P=.004) and declined following treatment (F3-4, 93.2±0.9 fL, P=.01; F0-2, 91.7±0.6 fL, P=.01). CONCLUSION Advanced hepatic fibrosis is strongly associated with arthritis in HFE hemochromatosis. The absence of arthritis predicts a low likelihood of advanced hepatic fibrosis, supporting its use as a clinical marker for advanced hepatic fibrosis in HFE hemochromatosis.

Abstract
There are multiple diseases or conditions such as hereditary hemochromatosis, hemophilia, thalassemia, sickle cell disease, aging, and estrogen deficiency that can cause iron overload in the human body. These diseases or conditions are frequently associated with osteoarthritic phenotypes, such as progressive cartilage degradation, alterations in the microarchitecture and biomechanics of the subchondral bone, persistent joint inflammation, proliferative synovitis, and synovial pannus. Growing evidences suggest that the conditions of pathological iron overload are associated with these osteoarthritic phenotypes. Osteoarthritis (OA) is an important complication in patients suffering from iron overload-related diseases and conditions. This review aims to summarize the findings and observations made in the field of iron overload-related OA while conducting clinical and basic research works. OA is a whole-joint disease that affects the articular cartilage lining surfaces of bones, subchondral bones, and synovial tissues in the joint cavity. Chondrocytes, osteoclasts, osteoblasts, and synovial-derived cells are involved in the disease. In this review, we will elucidate the cellular and molecular mechanisms associated with iron overload and the negative influence that iron overload has on joint homeostasis. The promising value of interrupting the pathologic effects of iron overload is also well discussed for the development of improved therapeutics that can be used in the field of OA.

Abstract
Rheumatology represents a discipline full of differential diagnoses. Even for classical diseases, such as rheumatoid arthritis as the most frequent chronic inflammatory joint disease and described so clearly in many textbooks, it is not uncommon that it can be a diagnostic challenge in daily practice. This applies to arthritic joint involvement and also to frequently associated extra-articular manifestations. The patient history and results of the clinical examination are essential; however, laboratory and imaging findings often make a significant contribution to confirming the diagnosis, especially in early phases of the disease. This article, which makes no claims to completeness, focuses on diseases that in the opinion of the authors can imitate rheumatoid arthritis due to similar joint and other organ manifestations. These include metabolic, inflammatory infective and non-infective as well as tumorous diseases. A misinterpretation as rheumatoid arthritis as a rule leads to long-term and severe consequences for affected patients. Thus, the diagnosis of rheumatoid arthritis should be questioned and re-evaluated in cases of unusual accompanying symptoms, atypical course of disease and a lack of response to standard treatment approaches.

Intracellular iron uptake is favored in Hfe-KO mouse primary chondrocytes mimicking an osteoarthritis-related phenotype. Biofactors 2019; 45:583-597.

Abstract
HFE-hemochromatosis is a disease characterized by a systemic iron overload phenotype mainly associated with mutations in the HFE protein (HFE) gene. Osteoarthritis (OA) has been reported as one of the most prevalent complications in HFE-hemochromatosis patients, but the mechanisms associated with its onset and progression remain incompletely understood. In this study, we have characterized the response to high iron concentrations of a primary culture of articular chondrocytes isolated from newborn Hfe-KO mice and compared the results with that of a similar experiment developed in cells from C57BL/6 wild-type (wt) mice. Our data provide evidence that both wt- and Hfe-KO-derived chondrocytes, when exposed to 50 μM iron, develop characteristics of an OA-related phenotype, such as an increased expression of metalloproteases, a decreased extracellular matrix production, and a lower expression level of aggrecan. In addition, Hfe-KO cells also showed an increased expression of iron metabolism markers and MMP3, indicating an increased susceptibility to intracellular iron accumulation and higher levels of chondrocyte catabolism. Accordingly, upon treatment with 50 μM iron, these chondrocytes were found to preferentially differentiate toward hypertrophy with increased expression of collagen I and transferrin and downregulation of SRY (sex-determining region Y)-box containing gene 9 (Sox9). In conclusion, high iron exposure can compromise chondrocyte metabolism, which, when simultaneously affected by an Hfe loss of function, appears to be more susceptible to the establishment of an OA-related phenotype.

Abstract
A variety of rheumatologic disorders may affect the liver. There is a significant epidemiologic, genetic, and immunologic overlap between immune-mediated rheumatologic disorders and autoimmune liver diseases. There is an increased frequency of autoimmune liver diseases, such as primary biliary cholangitis, autoimmune hepatitis, primary sclerosing cholangitis, or overlap syndrome, in patients with systemic lupus erythematosus, rheumatoid arthritis, Sjögren syndrome, systemic sclerosis, vasculitis, and other immune-related diseases. Non-immune-mediated rheumatologic diseases such as gouty arthritis may also have hepatic manifestations. Furthermore, medications used to treat rheumatologic diseases occasionally cause liver dysfunction. Conversely, primary immune-mediated and non-immune-mediated liver disorders may present with rheumatologic manifestations.

Abstract
Background Chronic arthropathy occurs in approximately two thirds of patients with hereditary haemochromatosis (HH). The aim was to study inflammatory and structural lesions in patients with HH with (HH-A) and without arthropathy (HH-WA) using ultrasonography. Methods This was a cross-sectional study of 26 patients with HH-A, 24 with HH-WA and 37 with hand osteoarthritis (HOA). Clinical examination was performed in 68 joints, and we retrieved data on hand function, pain and global disease activity (all using a visual analogue scale (VAS)), morning stiffness and ferritin levels. Standard x-ray and ultrasound were conducted in 36 joints (hands, hips, knees and ankles), and we graded grey scale synovitis (GSS), power Doppler ultrasound (PD), osteophytes, erosions, tenosynovitis and cartilage damage semi-quantitatively in accordance with prior publications. Results Ultrasound revealed a high proportion of inflammatory changes in HH-A; GSS was found in 96.2% and PD signals in 80.8% of patients (median GSS score 9, PD score 2.5). The frequency of these findings was similar in HOA. Inflammation was also common in HH-WA, yielding GSS in 83.3% and PD signals in 50.0% of patients. Cartilage damage was most prominent in HH-A as compared to HH-WA and HOA (median scores 11.0, 2.5 and 2.0, respectively). The prevalence and extent of erosions and osteophytes were similar in all groups. None of the ultrasound scores was associated with pain or function; GSS, PD, osteophyte and cartilage scores correlated with x-ray-verified structural damage. Conclusion A high prevalence of ultrasound-verified inflammation and cartilage damage was found in HH-A, and to a lesser extent in HH-WA. These findings were associated with x-ray-verified damage but not with clinical scores of pain and function.

Abstract
Hereditary hemochromatosis is a frequent autosomal recessive iron storage disease in northern and western Europe. The classical clinical triad of liver cirrhosis, hyperpigmentation and diabetes is nowadays rare, most probably because of early recognition. The homozygous C282Y mutation in the HFE gene is responsible for most cases of hereditary hemochromatosis, although other much rarer mutations in other genes have been recently identified. Progressive iron overload not only causes liver cirrhosis but also triggers development of a characteristic arthropathy. Bony swelling with intermittent arthritis of the second and third metacarpophalangeal joints is typical as well as occurrence of chondrocalcinosis in wrists and knee joints. The therapy of choice is excess iron removal by phlebotomy. Treatment usually prevents or even reverses liver damage but does not alter the course of hemochromatosis arthropathy.

Abstract
OBJECTIVE Kashin-Beck Disease (KBD) is a rare and severe osteoarthropathy endemic to China. We evaluated the frequency and patterns of hand radiographic osteoarthritis (rOA) in adults with and without KBD. METHODS Han Chinese (N = 438) from Yongshou County of central China underwent right hand radiography for determining case status. Presence of KBD was based on characteristic radiographic deformities of articular ends of bones including articular surface depression, carpal crowding, any subchondral bone deformities in the proximal end of phalanges or first metacarpal bone, or the distal ends of metacarpal bones 2-5, and any bony enlargement with deformity of the distal ends of phalanges. Hand rOA severity was determined by osteophyte (OST), joint space narrowing (JSN), and Kellgren and Lawrence (KL) grades. RESULTS This study included 127 KBD and 311 non-KBD adults of similar mean age (39 years) and body mass index (BMI) (21 kg/m(2)). Inter- and intra-rater reliability for radiographic determination of case status and rOA features was high (kappa 0.72-0.96). Compared to non-KBD, KBD adults had significantly more severe hand rOA of the thumb, distal interphalangeal (DIP), proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints. Only KBD adults had end-stage carpometacapal (CMC) disease. In KBD, DIPs and PIPs were more affected than MCPs and the frequency of OSTs was significantly higher in PIPs than DIPs. CONCLUSIONS Compared with age-matched adults from the same area and farming occupation, KBD hand rOA was more widespread and severe, particularly of PIPs and CMCs. The ability to differentiate adult KBD from non-KBD hand rOA will facilitate genetic analyses of the vast majority of affected individuals.

Abstract
Hereditary hemochromatosis is a frequent disease in Caucasian populations. It leads to progressive iron overload in a variety of organs. The most common cause is the C282Y homozygous mutation in the HFE gene. The classical triad of skin hyperpigmentation, diabetes, and liver cirrhosis is nowadays rare but musculoskeletal symptoms are common in HFE-related hemochromatosis. Typically the second and third metacarpophalangeal joints, and the wrist, hip, and ankle joints are affected. Clinical symptoms include osteoarthritis-like symptoms, pseudogout attacks, and synovitis sometimes resembling rheumatoid arthritis. Radiographs show degenerative changes with joint space narrowing, osteophytes, and subchondral cysts. Chondrocalcinosis in the wrist and knee joints is seen in up to 50 % of patients. Although most other organ manifestations regress during phlebotomy, musculoskeletal symptoms often persist or even become worse. Importantly, patients are at an increased risk of severe large-joint arthritis necessitating joint replacement surgery. Therefore, future research should focus on the pathogenesis and treatment options for HH arthropathy.

Abstract
Abstract
Objective
Osteoarthritis (OA) of the hand can be a debilitating condition that hinders an individual's quality of life. With multiple joints within the hand that are commonly affected OA, an individual's ability to use their hand in everyday movements become more limited. The article aims to review literature on the aetiology and pathogenesis of OA, risk factors, characteristics of hand OA and the steps of diagnosis.
Key findings
The aetiology and pathogenesis of OA, in particular hand OA, is not fully understood. However, it is known that several factors play a role. Environmental factors, such as stress from mechanical loading, especially to vulnerable joints predispose individuals to developing OA. Extracellular matrix changes in protein levels have also been noted in individuals with OA. Linked to hand OA development are boney enlargements (Herbeden's and Bouchard's nodes). Several risk factors for OA include: age, obesity, gender, smoking, genetics, diet and occupation. Various diagnostic methods include a combination of using radiographic methods, clinical presentation, a number of developed measurements and scales.
Summary
With OA having several risk factors and various causes and contributing elements, it is important to elucidate the pathogenesis of OA and determine exactly how risk factors play a role in its development. Because of the contributions from several elements, diagnosis is best when it uses multiple methods. In turn, understanding OA and making better diagnoses could lead to improved management of the condition through both pharmacological and non-pharmacological interventions.

Abstract
PURPOSE To evaluate the clinical effectiveness of metacarpophalangeal (MCP) arthroplasty for nonrheumatic arthritis. We hypothesized that MCP arthroplasty would produce significant improvement in objective measures of hand function, pain relief, and overall patient satisfaction. METHODS This retrospective study evaluated 30 patients with 38 MCP arthroplasties for nonrheumatic arthritis over a 12-year period. Follow-up assessment was completed at an average of 56 months after surgery. Objective measures included range of motion; grip and pinch strength; Disabilities of the Arm, Shoulder, and Hand (DASH) score; and visual analog pain score. A subjective patient questionnaire was used to assess patient satisfaction. RESULTS There was marked improvement between preoperative and follow-up range of motion, DASH, and pain. Linear regression showed strong correlations between preoperative measurements and improvement at follow-up. No difference was detected for grip or pinch strength. Results of the questionnaire showed that 73% were very satisfied, 87% would definitely do it again, and 70% experienced rare or no pain. Follow-up x-rays showed 5° mean angulation and 2-mm mean subsidence compared with immediate postoperative x-rays. Four arthroplasties (11%) required revision. CONCLUSIONS This study showed improved range of motion and DASH score, excellent pain relief, and excellent patient satisfaction in patients undergoing MCP arthroplasty for nonrheumatic arthritis. Patients with more severe range of motion limitation, DASH score, and pain score experienced a greater improvement of these measures at follow-up. Strength improvement was limited although it remained comparable to the nonoperated hand. Angulation, subsidence, and complications in the study population were consistent with those reported in the literature. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic III.
