Musculoskeletal Manifestation of Renal Failure Thomas Bardin Fédération de Rhumatologie Hôpital Lariboisière Université Paris Diderot Paris


Septic arthritis in hemodialysis patients     

Incidence is increased # 100 fold Gloomy prognosis Mono or polyarticular Coexisting amyloid arthropathy Fever, increased ESR or CRP may be missing or attributed to other cause Joint fluid aspiration before antibiotics +++ inflammatory WBC microorganism identification antimicrobial sensitivity


Septic arthritis in hemodialysis patients AURA dialysis Center, Paris (389 patients) 15 septic arthritides in 15 years incidence: 1.1/100 patient-years Amyloid arthropathy: 11/15 No association with diabetes Portal of entry: fistula 2, articular injection 2, cutaneous 2, lung 1, biliary 1 Staphylococcus +++, Streptococcus + 2 death, 3 sequellae (1 amputation)


Crystal -induced arthropathies in renal failure patients • Gout seen in renal failure before dialysis very rare in dialysis patients

• CPPD same as population at large

• BCPs very common

• Calcium

oxalate

primary or secondary oxalosis in dialysis patients


Periarticular BCP deposits in dialysis patients


Calcium phosphate periarticular deposits


Paraarticular calcification with adjacent bone erosion (ABD + Ca CO3)


Uremic tumoral calcinosis

Frequent multiple Bone scan : increased uptake Palpable mass Joint motion limitation Nerve or vein compression Rarely inflammatory


CALCIFIED TENDINITIS IN CKD PATIENTS MANAGEMENT

Curative : short course of NSAIDs (full dosage) Preventive : low dose NSAIDs (colchicine is contra indicated) Correction of etiological disorder (hyperphosphatemia, secondary HPP,stop calcium and vitD derivates)


Calcium oxalate crystals in dialysis patients Primary oxalosis Secondary oxalosis Decreased renal excretion: End-stage renal disease and dialysis Increased ingestion of oxalate precursors: Ascorbic acid Methoxyflurane Ethyleneglycol Increased absorption:

Small bowel resection

Increased production:

Thiamine or pyridoxine deficiency


Calcium oxalate crystals in SF

Dihydrate : weddelite

Monohydrate : whewellite


Calcium oxalate chondrocalcinosis


Oxalosis : Finger flexor involvement


Beta2 microglobulin amyloid: Main deposits : joints May also be systemic Pathophysiology Lack of renal catabolism Insufficient elimination by dialysis Increased synthesis due to cytokine release in contact with dialysis membranes and/or dialysate Risk factors Length of dialysis therapy Age Dialysis technique

β 2M amyloidosis: clinical features CTS (≈ 50% of CTS of dialysis patients) Chronic artropathy •

predominant involvement of shoulders and hands

bursa and tendon involvement

less than 1000 cells in SF

Subchondral bone erosions Destructive arthropathy Still seen in very long trem dialysis patients


DIALYSIS SHOULDER Calcified tendinitis: acute inflammatory flares Amyloid arthropathy: chronic shoulder pain frequently worsened by dialysis session usually bilateral - amyloid synovitis - bursal involvement - rotator cuff thickening: impigement syndrome










Destructive spondylarthropathy in dialysis patients (Kuntz et al, 1984)

Intervertebral space narrowing Erosions of adjacent vertebral plates No osteophytosis

Destructive arthropathy of large limb joints in dialysis patients

- hip, knee, shoulder, wrist - frequently multiple involvement - subchondral bone erosion precede JS narrowing, which is frequently rapid -traitement : total joint prothesis - pathology : amyloidosis



Destructive amymoid arthropathy of the wrist



Trapezo-metacarpal arthropathy in dialysis patients


Management of β 2m amyloid arthropathy Standard analgesics NSAIDs : increased risk of gastric ulcer complications COXIBs : vascular risk Prednisone : 0.1 mg/kg/day Steroid injections : contraindicated (sepsis) Radiation synovectomy Highly permeable and biocompatible membranes


Management of β 2m amyloid arthropathy Carpal tunnel syndrome: early release of median nerve Destructive spondylarthropathy with neurological compromise: interbody fusion of instable levels Destructive arthropathy of the hip and knee: total joint prosthesis



Dialysis amyloidosis Renal transplantation Rapid pain improvement Subchondral erosions persist but do not progress Destructive arthropathy may worsen Amyloid deposists persist


EROSIVE ENTHESOPATHY IN CKD

Etiology Severe (primary or) secondary HPT Clinical features Pain on use Tendon rupture Management correction of HPT (PTX or Mimpara)


Tendon Rupture in CKD Patients

Secondary hyperparathyroidism Corticosteroids Fluoroquinolones


Bone Fissures in Dialysis patients Symptom • •

Pain on use, usually of the lower limb Triggered by weight bearing

Value of bone scan Etiology • • •

Osteomalacia due to vit D deficiency Fluorosis Osteoporosis


Fractures in Dialysis Patients Age and sex adjusted relative risk of hip fracture in a national US register: • •

4.44 in men 4.40 in women

Alam et al. Kidney Int 2000; 58:366-9


Risk Factors for Osteoporotic Fractures in Renal Failure Patients Age Female sex Caucasian Early menopause Steroids Denutrition Low DMO

Duration of survival upon dialysis Peripheral arteriopathy Vascular calcification Al intoxication Other types of renal osteodystrophy


Effect of PTH levels on fracture Coco & Rush. Am J Kidney Dis 2000


Vertebral fractures and vascular calcifications in dialysis patients

Rodriguez-Garcia Nephrol Dial Transpl 2009;24:239-46


Treatment of osteoporosi in CKD patients Prevention and treatment of osteodystrophy Estrogens in early menopause General measures exercise, correct nutrition Other treatments are contraindicated Raloxifene increases BMD


Muskuloskeletal Manifestations of Renal Failure Frequent and diverse, especialy in dialysis patients Septic arthritis is increased and severe BCP deposition is favoured by renal osteodystrophy Beta-2 amyloid is still observed in long term dialysis patients IA steroid injections should be avoided Osteoporosis is frequent and remains a therapeutic challenge
