Management of Achilles Tendinitis and Bilateral Sacroiliitis in CKD Stage 3B

Critical Medication Considerations in CKD Stage 3B

The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommend avoiding NSAIDs in patients with CKD stage 3B due to nephrotoxicity risk and potential for acute kidney injury, and instead suggest low-dose colchicine or glucocorticoids for symptomatic inflammatory conditions 1, 2, 3
The KDIGO guidelines explicitly state that for symptomatic inflammatory conditions in CKD, low-dose colchicine or glucocorticoids are preferable to NSAIDs 1, 2, 3

Physical therapy should emphasize supervised active exercise interventions over passive modalities like massage, ultrasound, or heat, with land-based physical therapy preferred over aquatic therapy 5
Low-dose colchicine is the preferred pharmacologic option given the CKD and NSAID contraindication, with oral glucocorticoids (short course, low dose) considered for acute symptom control 1, 2, 3
Avoid peri-tendon injections around the Achilles tendon as these carry rupture risk 5

Low-dose colchicine or oral glucocorticoids are the preferred systemic anti-inflammatory options given the CKD, with intra-articular glucocorticoid injections conditionally recommended over no local treatment for isolated active sacroiliitis 1, 2, 3, 5
Systemic glucocorticoids should be used cautiously and for short durations only, with physical therapy strongly recommended as it improves outcomes in axial spondyloarthropathies 5

Initiate statin therapy immediately (rosuvastatin 5 mg daily, maximum 10 mg daily) for cardiovascular risk reduction in patients with CKD stage 3B 4
Consider plant-based Mediterranean-style diet to complement lipid-lowering therapy, with estimation of 10-year cardiovascular risk using a validated tool 4, 6, 7
Limit alcohol, meats, and high-fructose corn syrup intake as these may contribute to inflammatory conditions, with individualized dietary counseling through a renal dietitian advisable for CKD stage 3B 1, 2, 7

Never prescribe NSAIDs in CKD stage 3B, even for short-term use, as this significantly increases risk of acute kidney injury and CKD progression 1, 2, 3
Avoid peritendinous injections around the Achilles tendon due to rupture risk, and do not use systemic glucocorticoids long-term for axial spondyloarthropathy 5
Do not overlook statin therapy as cardiovascular disease is the leading cause of mortality in CKD patients 4
