The Matter of Kidney Biopsy in Monoclonal Gammopathy of Renal Significance: A Case Report of a New Pattern of Immunoglobulin-Storing Histiocytosis.

Monoclonal gammopathy of renal significance (MGRS) represents a group of disorders, characterized by paraproteinemia which causes renal damage. These disorders never meet the diagnostic criteria for multiple myeloma (MM) or lymphoproliferative disease. Crystal-storing histiocytosis is one of the rarest patterns of MGRS, characterized by an accumulation of light chains of crystals within histiocyte's cytoplasm, located in bone marrow or other extramedullary sites such as the kidney, cornea, or thyme.

Low-protein vegetarian diet with alpha-chetoanalogues prior to pre-emptive pancreas-kidney transplantation.

Background: Pre-emptive pancreas-kidney transplantation is increasingly considered the best therapy for irreversible chronic kidney disease (CKD) in type 1 diabetics. However, the best approach in the wait for transplantation has not yet been defined.

Aim: To evaluate our experience with a low-protein (0.

Lost to follow-up: the bottleneck of early referral to renal units?

Background: Early referral is a major goal in chronic kidney diseases; however, loss to follow-up, potentially limiting its advantages, has never been studied.

Material/methods: In order to assess the prevalence and causes of loss to follow-up, a telephone inquiry was performed in a renal outpatient unit, mainly dedicated to early referral of diabetic patients. Patients were considered to be in follow-up if there was at least one check-up in the period February 2001-February 2002, and lost to follow-up if the last check-up had occurred in the previous year.

Kidney rupture: an unusual and oligosymptomatic complication in a dialysis patient with acquired cystic disease.

Acquired cystic kidney disease (ACKD) is a complication of end-stage renal disease, the prevalence of which is related to dialysis duration; incidence of ACKD and associated conditions (neoplasia, hemorrhage) have decreased with improvements in renal transplantation and with the ageing of the dialysis population. This report regards spontaneous kidney rupture in a 57-year old patient, on home hemodialysis for 11 years, with ACKD for 5 years. At the end of a dialysis session, the patient reported sudden onset of colicky flank pain, followed by macrohematuria.

Patients on renal replacement therapy for 20 or more years: a clinical profile.

Background: Long-term survivors are living evidence of the goals and limits of renal replacement therapy (RRT).

Methods: A cross-sectional study was performed on all cases (188 patients) with RRT follow-up >/=20 years in Piemonte, northern Italy (4 350 000 inhabitants, 22 dialysis centres). Study included revision of clinical charts and assessment of functional (Karnofsky scale, Ks) and nutritional status (subjective global assessment, SGA).

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.

Daily Dialysis: Toward a New Standard in Well-Being.

Daily hemodialysis (DHD) is a promising option; however, logistic obstacles and clinical perplexities limit its dissemination. Understanding the mechanisms of, and the time until, the onset of improved well-being may help to quantify clinical advantages and to define the minimum length of a "trial" of daily dialysis. By following 30 patients treated in 4 centers, this study aimed to determine how long a period of time is needed until a patient experiences subjective improvement.

Daily Dialysis and Flexible Schedules: How to Assess Kt/V and EKR ?

Despite the growing interest in daily hemodialysis (DHD), logistic and economic factors limit its dissemination. Not the least of these factors is the lack of uniform criteria for measuring efficiency. From November 1998 to November 2000, 19 patients were on DHD in our unit.

Why Our Patients Like Daily Hemodialysis.

The option of daily hemodialysis (HD) was discussed in November 1998 with a group of 35 HD patients on home or self-care/limited-care HD in a single, freestanding unit. After the meeting, 3 patients on home HD chose to switch to daily HD. The clinical success of the first patient and the immediate followers was one of the main reasons for further extension of this experience.
