Early referral of Type 2 diabetic patients: are we ready for the assault?

BACKGROUND: Elderly diabetics on dialysis are dramatically increasing in number. Their late referral reduces efficacy of therapeutic interventions; early referral is fundamental for their survival on dialysis. However, need for nephrological follow-up in case of early referral is not assessed. The objective was to define the need for follow-up in the nephrology setting of Type 2 diabetics, according to the early referral criteria of serum creatinine > or = 1.5 mg/dl or macroproteinuria. METHODS: The setting of the study was an outpatient diabetic care unit (University of Torino), where approximately 25% of the Type 2 diabetics of a 900,000-inhabitant city (Torino, Northern Italy) were followed. At the time of the study (1998-1999) the unit followed 5182 Type 2 diabetics whose serum creatinine and proteinuria were tested at least yearly. A total of 3826 prevalent and 478 incident patients with one or more analyses in the same laboratory were included in the study. Demographic data were not statistically different between selected and excluded patients. We calculated the stepwise need for nephrological follow-ups calculated according to our usual policy (4-12 evaluations/ year, on serum creatinine and proteinuria, and 30 min/evaluation). RESULTS: The prevalence of increased serum creatinine and macroproteinuria was high (in the prevalent cohort: serum creatinine > or = 1.5 mg/dl, 8.1%; proteinuria 0.3 g/day, 25.2%; serum creatinine > or = 3 mg/dl, 1.2%; nephrotic proteinuria 3.4%). Projecting data to the entire unit, with adherence to our evaluation protocol, early nephrological follow-up of Type 2 diabetics requires approximately 1300 h/year (one full-time nephrologist); five nephrologists are needed for our city, and 24 for the region (4350 000 inhabitants). CONCLUSIONS: Early nephrological referral and follow-up of Type 2 diabetics is time consuming and expensive. Meeting the outpatient care needs of this critical cohort requires considerable resources.

Ankylosing spondylitis: a difficult diagnosis in patients on long-term renal replacement therapy.

We report the case of a 48-year-old male, whose musculoskeletal manifestations, previously related to long-term renal replacement therapy (RRT), were diagnosed as ankylosing spondylitis when symptoms changed their pattern on daily hemodialysis (DHD). The patient started RRT in 1981; in 1985 he received a cadaver graft, which failed in 1987. Secondary hyperparathyroidism, amyloid geoids, bilateral carpal tunnel syndrome and high aluminium levels were present. Musculoskeletal pain, reported since 1986, involved feet, heels, hips, shoulders, hands, spine. Symptoms impairing daily life did not improve after parathyroidectomy. He developed chronic hypotension and recurrent atrial fibrillation. In 1994 and 1998, because of thoracic pain, coronarography was performed (normal on both occasions). In June 2000, DHD was started. Equivalent renal clearance increased from 9-12 to 15-17 mL/min. Well-being remarkably improved. In September 2000, musculoskeletal pain worsened and bilateral Achilles tendinitis occurred. The worsening of musculoskeletal symptoms despite the improvements in well-being and other dialysis related symptoms prompted a re-evaluation of the case. The diagnosis of ankylosing spondylitis was based on: history of plantar fasciitis, bilateral Achilles tendinitis, inflammatory spinal pain with limitation of lumbar spine mobility (positive Schober test), radiological evidence of grade 2 bilateral sacroiliitis, presence of HLA-B27. This diagnosis cast light on the episodes of chest pain, explained by enthesopathy at the costosternal and manubriosternal joints and atrial fibrillation, due to HLA-B27 associated impairment in heart conduction. This case exemplifies the difficulty of differential diagnosis of multisystem illness in patients with long RRT follow-up.

Flexibility as an implementation strategy for a daily dialysis program.

BACKGROUND: Daily hemodialysis (DHD) is an interesting dialysis option, experienced worldwide by only a few hundred patients, because of clinical and logistic limitations. This study describes the main clinical and implementation results of a flexible policy applied in starting a DHD program. METHODS: The setting is the University Nephrology Center of Turin, Italy (approximately 150 hemodialysis and 50 peritoneal dialysis (PD) patients) where in November 1998 a short daily DHD program was started. Outcome measures were logistical (enrollment rate, indications and drop-outs) and clinical (dialysis efficiency, metabolic control, hypertension and anemia control). RESULTS: 25 patients experienced DHD, 16 (11% of the hemodialysis pool) were on DHD in November 2001; overall the DHD follow-up was 409.1 months (median 18, range 0.7-36 months). Flexibility was applied to schedules (patients modulated dialysis time and could switch to 3-4 sessions/wk); treatment setting (home: 11 patients, limited care center: 13; alternate settings: one); clinical selection (23/25 patients with comorbidity). Main reasons for choice were poor tolerance of previous schedule and the search for "best" treatment. Five patients dropped out (work reasons), one died on DHD and three were grafted. As compared to baseline, dialysis efficiency increased (EKRc pre-DHD 14.5 +/- 2.1 mL/min; 17.4 +/- 2.8 mL/min and 17.7 +/- 3.5 mL/min at 1-6 months; p<0.000). Despite the potentially confusing effect of comorbidity, the main clinical data improved. CONCLUSIONS: A flexible approach allowed development of DHD in approximately 11% of hemodialysis patients, with promising clinical results, despite frequent comorbidity.
