Tendinopathy is the appellation acclimated to call aching bond conditions.1 While the exact pathoaetiology of tendinopathy charcoal unclear,2 overuse is advised as a above accidental factor.3 Despite this link, about one-third of cases action in non-active individuals.4 Blubber and fat administration accept been associated with tendinopathy,5–7 with one account actuality that college anatomy accession causes added bond loading (mechanical hypothesis).7 However, added anatomy accession base (BMI) has additionally been affiliated with tendinopathy in the non-weight-bearing aerial limbs,8 which suggests that a automated antecedent does not abundantly explain changes to bond anatomy or access of bond pain.6 There is growing affirmation for a metabolic antecedent bond BMI and tendinopathy.

A acclaimed comorbidity of blubber is hypercholesterolaemia, an accustomed accident agency for coronary affection disease.9 Cholesterol additionally accumulates in tendons, breadth it may be complex in structural disruption of the collagen matrix, agnate to that apparent in tendinopathy.10–12 This has been approved in patients with familial hypercholesterolaemia (FH), a abiogenetic lipid metabolism ataxia that is characterised by constant acclivity of serum cholesterol.13 Substantial cholesterol degradation occurs in FH and is accepted as bond xanthoma.14 While abounding medical textbooks accompaniment that bond xanthomas are asymptomatic, abstracts appearance a sixfold access in the lifetime accident of Achilles bond affliction associated with FH.15

Chronic low-grade deepening (para-inflammation) is a analytical disciplinarian of cardiovascular ache (CVD) and is additionally a absolute affection of FH.16 ,17 The instigating accident in CVD is assimilation of apolipoprotein-B absolute lipoproteins below the endothelial band of the claret barge wall18 breadth they are irreversibly adapted via alternation with extracellular cast proteoglycans.19 Subendothelial lipoprotein assimilation triggers the absolution of chemokines, which advance monocyte application and about-face to macrophages.17 As these macrophages blot and action retained lipoproteins, they accrue cytoplasmic lipid droplets, and beneath the microscope these aerosol attending like soap bubbles, arch to the appellation ‘foam cells’.20 Eventually cholesterol esterification and address mechanisms are afflicted and the balance cholesterol becomes cytotoxic.21 Anniversary of these accomplish contributes to the para-inflammation present in CVD and FH.22

Recent studies of non-ruptured tendinopathy tissue announce attenuate increases in mast beef and macrophages23 ,24 although added studies acquisition no such increase.25 ,26 When the analyst is because this new information, it is alarmingly important to bethink that para-inflammation is triggered by attenuate alterations in tissue homeostasis rather than infection and trauma, which are the accustomed triggers of astute (triphasic) inflammation.27 Therefore, para-inflammation is not triggered by a bender of changing astute deepening but is a acknowledgment to tissue accent that is maintained over an continued aeon of time.27 Similarly, archetypal proinflammatory cytokines (eg, tumour afterlife agency alpha) can accept anti-inflammatory furnishings via alternating signalling pathways.26

Other studies accept articular associations amid cholesterol and bond rupture28 ,29 and abiding tendinopathy.6 Together, these abstracts body abutment for the metabolic antecedent as an account for the presentation of tendinopathy amid desk individuals.

A analytical assay by Gaida et al7 appear that a accord exists amid adiposity and tendinopathy. As an aberrant lipid contour is frequently associated with obesity,30 this assay has provided a base for a afterpiece assay of this relationship. Thus, the primary aim of this analytical assay was to investigate whether there is an affiliation amid aberrant lipid levels and changes in bond anatomy or bond pain. A accessory aim was to call the affiliation that lipid-lowering drugs accept with bond anatomy or bond pain. The assay alone advised individuals not diagnosed with FH.

Six cyberbanking databases (MEDLINE, Cochrane, AMED, Web of Science, Scopus and EMBASE) were searched in April 2014. Medical accountable headings acclimated in the chase included (1) Tendons, Bond Injuries, Tendinopathy, Xanthomatosis AND (2) Lipids, Lipoproteins, Cholesterol, Hydroxymethylglutaryl-CoA Reductase Inhibitors and Lovastatin. Chargeless argument agreement were additionally searched with adapted truncation, and included (1) bond structure, bond thickness, tend#nopathy, tend#nos#s, bond affliction and (2) lipid, cholesterol, high-density lipoprotein, low-density lipoprotein, triglyceride, statin, hydroxymethylglutaryl-CoA reductase inhibitors (for complete account of chase terms, see online added addendum A). All annal were again alien into advertence administration software (Endnote adaptation X5).

One columnist (BT) activated predefined accommodation belief to the appellation and abstracts of the retrieved records. To be included studies had to accommodate abstracts on both lipid levels or lipid-lowering drugs and bond anatomy or bond pain. We afar case reports, case alternation and attendant studies, reviews, letters, appointment abstracts, comments, editorials, non-English articles, and studies of non-human, body or biopsy material. Affidavit that complex participants with cerebrotendinous xanthomas, anarchic or systemic arthritis, or FH were excluded. However, FH affidavit were included if they presented bond abstracts from a non-FH ascendancy group. In the additional annular of reviewing, the abounding argument was apprehend to actuate whether the commodity met the admittance and exclusion criteria.

Included affidavit were adjourned for abstruse affection to analyze abeyant sources of bias. A apparatus was developed by the authors based on the affection appraisal belief developed by Downs and Black (see online added addendum B).31 The apparatus consisted of 11 criteria, anniversary acclamation a adapted antecedent of bias. An absolute accommodation aphorism was developed for anniversary archetype to advance precision. Affection appraisal after-effects were adapted to a allotment account as not all studies could be apparent on all criteria.

Data were extracted by one columnist (BT) and included abstraction details, actor demographics, bond outcomes, lipid outcomes, and any after-effects presented (ie, aftereffect size, allowance arrangement (OR)). If abstracts for the lipid levels of participants were presented in milligrams per decilitre (mg/dL), these units were adapted to millimole per litre (mmol/L) application adapted calculations (see online added addendum C). When necessary, abstracts were extracted from abstracts application Engauge Digitilizer (Mitchell, M; V.4.1) (see online added addendum C).

Meta-analysis was conducted on adapted abstracts application RevMan (The Cochrane Collaboration; V.5.1). A accidental furnishings archetypal was acclimated with changed about-face weighting, and after-effects presented as beggarly aberration (MD). A meta-analysis was conducted for anniversary of the four lipid abstracts (total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and triglycerides (TG)), and their alone affiliation with bond anatomy or bond pain.

The databases chase crop of 1607 affidavit was alien into Endnote and 561 duplicates were removed. The appellation and abstruse of 1046 affidavit were advised and 962 studies were removed. The abounding argument adaptation of 84 affidavit was advised and 67 studies were removed. In the end, 17 studies were included in the assay (figure 1).

The affection of the included affidavit showed ample variation, with the beggarly affection appraisal account actuality 62% (range 20–82%), suggesting that the accepted abstract in this breadth is of abstinent affection (see online added addendum D). The majority of studies appear their adjustment of actor recruitment; however, these participants were not frequently adumbrative of the citizenry from which they were recruited. The case–control attributes of all but one of these studies explains why the two groups were generally taken from adapted populations. With the barring of Ozgurtas et al,29 authors appear that controls were chargeless from disease. The majority of authors presented a ascendancy accession that was akin to the case accession with account to abeyant abashing factors. Reporting the adjustment acclimated to appraise bond anatomy was a accepted belief met by these papers, however, these methods were not consistently identical for cases and controls. Alone one study6 appear adjudicator blinding, with the butt of the studies accepting the abeyant for adjudicator bias.

Fifteen of the included affidavit acclimated a case–control abstraction design, and two acclimated a cross-sectional architecture (table 1). Imaging was acclimated to ascertain bond anatomy in 14 studies—7 acclimated ultrasound, 2 acclimated MRI, 1 acclimated CT and 4 acclimated radiography. A array of methods were acclimated to appraise bond symptoms, including palpation, analytic history and a beheld alternation calibration for pain. The tendons advised included rotator belt (n=4) and Achilles bond (n=13).

Among the case–control papers, there were bristles studies that recruited the case accession based on bond anatomy or bond pain,6 ,29 ,32–34 and three studies that recruited the case accession based on lipid abnormalities.35–37 There were seven studies of FH breadth alone the ascendancy accession was included.13 ,14 ,38–42 Two studies advised the cross-sectional accord amid bond bloom and lipid profiles.8 ,43 In three of the bristles studies that recruited based on bond anatomy or bond pain, cogent differences in lipids or statin use were identified. In two of the three studies that recruited on lipid levels, cogent differences in bond affliction or anatomy were identified.

Data were extracted from all 17 affidavit in the assay (see online added addendum E), of which bristles were affiliated for meta-analysis.6 ,8 ,29 ,32 ,34 These affidavit acclimated lipid levels as the connected variable, for both case and ascendancy bond bloom groups. The non-FH ascendancy groups from the seven FH studies13 ,14 ,38–42 were not included in the meta-analysis. Achilles bond array (ATT) was acclimated as a connected aftereffect capricious in two studies that anniversary had a aerial and a low lipid group,35 ,37 about one of these advised men and women alone and so the two could not be compared adjoin anniversary other. Two studies provided angled abstracts on bond pathology; about one cardboard advised the affiliation with lipid levels,36 while the added advised the affiliation with statin use,33 appropriately the affidavit were presented separately. Finally, one cardboard was a cross-sectional abstraction and so could not be compared to the case–control studies.43

TC was decidedly college amid individuals with bond affliction or rupture, MD=0.66 mmol/L, 95% CI 0.11 to 1.21 (figure 2).

Forest artifice assuming the accord amid absolute cholesterol levels and bond anatomy (TC, absolute cholesterol).

HDL-C was decidedly lower amid individuals with bond affliction or rupture, MD=−0.19 mmol/L, 95% CI −0.30 to −0.07 (figure 3).

Forest artifice assuming the accord amid high-density lipoprotein cholesterol levels and bond anatomy (HDL-C, high-density lipoprotein cholesterol).

LDL-C was decidedly college amid individuals with bond affliction or rupture, MD=1.00 mmol/L 95% CI 0.23 to 1.77 (figure 4).

Forest artifice assuming the accord amid low-density lipoprotein cholesterol levels and bond anatomy (LDL-C, low-density lipoprotein cholesterol).

TG was decidedly college amid individuals with bond affliction or rupture, MD=0.33 mmol/L, 95% CI 0.15 to 0.50 (figure 5).

Forest artifice assuming the accord amid triglyceride levels and bond anatomy (TG, triglycerides).

One paper36 recorded the prevalence of bond anatomy (history of Achilles tendinitis or bond xanthomas) in a accession with alloyed hyperlipidaemia and a normolipidaemic ascendancy group. Bond anatomy was present in 18 (75%) of those with alloyed hyperlipidaemia, compared with none of the normolipidaemic participants.

Tendon array was acclimated as the connected capricious in two studies,35 ,37 attractive for differences amid the hyperlipidaemic case accession and the normolipidaemic ascendancy group. However, the cardboard by Gattereau et al35 analysed men and women alone and did not accommodate abstracts for the citizenry as a whole, and so the after-effects could not be compared with the cardboard by Kwak et al.37 Interestingly, as the above breach the participants into men and women, this cardboard accustomed an assay of whether or not this affiliation was greater in one sex compared with the other.

Gattereau et al35 acclimated absolute ethics for TC and TG of 240 and 140 mg/dL, respectively, to abstracted the hyperlipidaemic accession from the normolipidaemic group. Hyperlipidaemic capacity were begin to accept a decidedly added ATT compared to the normolipidaemic controls. This was axiomatic for both men (standardised MD (SMD)=0.95, 95% CI 0.19 to 1.71) and women (SMD=0.86, 95% CI 0.13 to 1.58). A cogent absolute alternation amid cholesterol and ATT was additionally found, with alternation coefficients of 0.85 for women and 0.63 for men.

Kwak et al37 acclimated the European Society of Cardiology analogue for dyslipidaemia (any one of the following: TC >240 mg/dL, TG >200 mg/dL, LDL-C >160 mg/dL, HDL-C <40 mg/dL). There was no cogent aberration in ATT amid the dyslipidaemic (0.44±0.04 cm) and ascendancy accession (0.45±0.02 cm, p=0.783). There was additionally no cogent alternation amid ATT and lipid parameters. The coefficients for TC was −0.09 (p=0.36), HDL-C −0.06 (p=0.50), LDL-C −0.03 (p=0.69) and TGs −0.04 (p=0.63).

One paper33 advised the affiliation amid statin assay and bond structure. Statin use was the aforementioned in those with and afterwards bond rupture, however, agreed subgroup assay showed an access in bond breach in women demography statins, OR=3.09 (95% CI 1.04 to 9.75). No added accident was articular in men, OR=0.62 (95% CI 0.3 to 1.3).

Seven FH affidavit with a non-FH ascendancy accession were included.13 ,14 ,38–42 Anniversary cardboard presented abstracts on ATT and lipid profiles, but alone one40 analysed this accord in the ascendancy group, award a abstinent absolute alternation (r=0.454, p<0.01).

Lipid ambit from the actual studies were affiliated application adapted equations (see online added addendum F;44 abstracts 6⇓⇓⇓–10).

Achilles bond array (ATT) beggarly (SD).

Total cholesterol (TC) beggarly (SD).

High-density lipoprotein cholesterol (HDL-C) beggarly (SD).

Low-density lipoprotein cholesterol (LDL-C) beggarly (SD).

Triglycerides (TG) beggarly (SD).

There was alone one study43 that acclimated affliction acuteness as an outcome. This was a abstraction of the affiliation of blubber and metabolic ambit with aerial acme pain. Age-adjusted and gender-adjusted ORs of affliction acuteness was affected for TC, HDL-C, LDL-C and TG. A aerial affliction acuteness was associated with both low HDL-C levels (OR 2.7, 95% CI 1.2 to 6.3) and aerial TG levels (OR 2.8, 95% CI 1.3 to 6.6; table 2).

This analytical assay showed with meta-analysis that bodies with adapted bond anatomy had decidedly college TC, LDL-C and TG, as able-bodied as lower HDL-C, than bodies with accustomed tendons. Individuals with an adverse lipid contour were abundant added acceptable to accept bond pathology, and to accept college affliction acuteness associated with aerial limb musculoskeletal injury. Statin use was associated with Achilles bond breach in women but not men. Finally, two of the three studies that activated ATT with lipid ambit begin a cogent absolute correlation. Together, these allegation accommodate cogent abutment for a metabolic antecedent of bond abrasion and accuse lipid ambit as a abeyant link.

OR of affliction acuteness according to TC, HDL-C, LDL-C and TG

While the abstracts in this assay announce a articulation amid lipid ambit and bond health, account cannot be accustomed from cross-sectional data. As bond abrasion banned concrete activity, about-face causation—tendon abrasion causing animated lipids—is accessible accustomed that metabolic ambit rapidly adulterate with complete bed rest45 and bargain circadian steps.46 However, empiric and mechanistic studies advance that adverse lipid ambit can be adverse to tendons. For example, individuals with FH accept adapted bond anatomy in boyhood and adolescence,47 and advancing lipid assay reduces bond thickness.14 Furthermore, mechanistic studies appearance that hyperlipidaemia alters the automated backdrop of bond beyond several species.48 ,49 Together, these abstracts accommodate believability for lipid ambit arch to bargain bond health, suggesting that about-face account is unlikely.

High cholesterol promotes the accession of cholesterol in macrophages and added accustomed cells, which drives para-inflammation. Downstream signalling pathways activate a abridgement in cholesterol efflux,22 which increases cholesterol accession and maintains the para-inflammation state.22 These processes accommodate a abeyant account for a articulation amid hypercholesterolaemia and tendinopathy. Supporting this antecedent is the added cardinal of mast beef and macrophages apparent in those with tendinopathy, compared with a advantageous ascendancy population.23 ,24 Additionally, the able anarchic phenotype of FH16 suggests that a accompaniment of para-inflammatory change may be complex in the apparatus of aerial cholesterol arch to tendinopathy.16 It is cryptic whether these processes additionally action in tendons, decidedly accustomed the consequence of hypercholesterolaemia acclaimed in affiliation with tendinopathy (eg, 5.7±1.2, affiliated beggarly of cases from amount 2) is far beneath than that empiric in FH (eg, 8.3±1.0 mmol/L).14

A accessory aim of this assay was to appraise whether statin use was activated with bond structure. One acceptable paper33 advised this affiliation and found, in an a priori subgroup analysis, that women demography statins had an added accident of bond rupture. Contempo affirmation suggests this aftereffect may be advised by changes in the contour of metalloproteinase enzymes aural the tendon.50 These enzymes are complex in remodelling the extracellular cast of bond and accept been affiliated with bond rupture.51

Pain acuteness was acclimated as an aftereffect in one paper43 and was begin to be associated with low HDL-C and aerial TG amid individuals with aerial acme bendable tissue disorders. This abstraction affiliated participants with a ambit of diagnoses, including tendinopathy of the rotator cuff, crabbed bend and wrist flexor tendons. Grouping diagnoses is, in one sense, a limitation of the study; however, this access accustomed the authors to aggregate a ample sample of participants with a contempo access of affliction (<1 month). The able affiliation of LDL-C and TG with contempo access affliction provides strong, but acutely not definitive, affirmation adjoin about-face causation.

The lipid changes associated with bond abrasion alongside those associated with CVD, namely, TC, LDL-C and TG are added while HDL-C is decreased. This suggests that bond and avenue acknowledge to their metabolic environments in agnate ways. Both are collagen-based tissues, able of responding to their loading environment. For example, annex credibility and bifurcations of arteries are apparent to microburst armament created by turbulence,52 accept an adapted proteoglycan content, and are decumbent to atherosclerosis development.53 The pathogenesis of atherosclerosis is apprenticed by abiding para-inflammation, involving the application and about-face of monocytes to macrophages.54 The macrophages accrue cholesterol esters to anatomy ‘foam cells’, which comedy a axial role in the accession of atherosclerotic lesions.54 In tendons, microburst and compression armament adapt the proteoglycan profile,55 and these areas are decumbent to pathology. There is affirmation that proteoglycan (particularly those with a chondroitin sulfate ancillary chain) precipitates cholesterol accession aural both bond and avenue through its able affection for cholesterol.56 ,57 In short, things that are bad for your affection additionally assume to be bad for tendons.

There are limitations of this assay that should be acknowledged. One limitation was that 17 potentially accordant non-English studies were excluded. Language bent has been approved for randomised trials58—studies with cogent allegation are added acceptable to be appear in English-language journals—and may additionally affect ascertainment studies such as those included in this review. Limitations are additionally inherent in the abstracts set acclimated for this review. For example, the included studies acclimated a array of methods to appraise bond anatomy or bond pain. Claret lipid assay is a standardised class action with little abeyant for analytical bias. Claret accumulating procedures, however, may acquaint bias. For example, in the abstraction by Ozgurtas et al,29 claret samples were calm from the case accession aural 6 h of bond rupture, while those from the ascendancy accession were calm afterwards an brief fast. While this is not ideal, ample datasets appearance basal aberration amid abnegation and non-fasting lipid measurements.59

The assay assiduously articular all accessible abstracts on the abeyant articulation that lipid fractions accept with bond affliction and structure. The meta-analysis supports an affiliation for TC, HDL-C, LDL-C and TG. A abeyant apparatus for this articulation is the para-inflammation that is present in FH. Ongoing assay is adapted to actuate whether agnate processes action in the attendance of beneath acute cholesterol elevations associated with affairs factors. Notwithstanding this, the accepted assignment indicates that there is absolutely an affiliation amid unfavourable changes in lipid ambit and tendinopathy.

This assay articular 17 studies on the affair of bond bloom and lipid profile. Bristles studies compared lipid contour amid individuals with and afterwards bond pain/abnormality, and three studies compared bond bloom amid individuals with and afterwards lipid abnormality. The cross-sectional accord amid bond bloom and lipid contour was advised in two studies. Seven studies on familial hypercholesterolaemia provided abstracts from their advantageous ascendancy group.

Meta-analysis of adapted studies showed decidedly college absolute cholesterol, low-density lipoprotein cholesterol and triglyceride, and lower high-density lipoprotein cholesterol in individuals with bond pain/abnormality.

Two of the three studies that advised the alternation amid bond array and lipid levels begin a cogent absolute relationship.

Statin use was associated with Achilles bond breach in women but not men.
