Combination of immunosuppressive agents in treatment of steroid-resistant minimal change disease and primary focal segmental glomerulosclerosis.

BACKGROUND: Minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS) are the most prevalent histopathological lesions in idiopathic nephrotic syndrome (INS). The latter is associated with high morbidity and mortality due to symptomatic anasarca, bacterial infections, venous and arterial thromboembolism, and potential progression to end-stage renal disease in the case of FSGS. Traditionally, most patients are treated with corticosteroids, cyclophosphamide (CTX) or calcineurin-inhibitors (C-I). Unfortunately, many patients become steroid or C-I dependent, with the inherent risk of long-term side effects, or are resistant to both. The aim of this paper is to report on our experience with a new protocol of a combination of immunosuppressive agents added sequentially to improve the response of steroid and C-I refractory or resistant-INS and to minimize the long-term side-effects of single-agent treatment. METHODS: Twenty-one patients with corticosteroid-resistant and C-I refractory INS (6 with MCD and 15 with FSGS) were treated prospectively over 6 and a half years. Our protocol consisted of an initial regimen of C-I followed by the addition of mycophenolate mofetil (MMF) and then by monthly intravenous CTX for 3 consecutive months. Dose reduction of C-I or/and MMF was attempted afterwards at 4-months intervals. Patients who remained refractory to the previously mentioned protocol were treated with an additional course of pulse Solu-Medrol given for 3 days followed by oral corticosteroids tapered over 6 months in addition to a second course of intravenous CTX given for 3 consecutive months. RESULTS: With the initial regimen, two patients with MCD, remained in complete remission (CR) without any therapy after the course of CTX. Fifteen patients had variable response to C-I and MMF, but they achieved CR after CTX and their initial dosage of C-I and MMF were reduced to nearly one half. The remaining four patients had refractory form of FSGS even after the initial regimen, yet responded with CR to the additional course of steroid/CTX. However, no success with dose-reduction, in C-I and MMF, was achieved in the latter four patients. CONCLUSION: Our study represents the first clinical trial with prospective and adequate follow-up of combination therapy of immunosuppressive agents in INS. This method is effective and safe for treatment of patients who are refractory to the conventional single-agent therapy.

Chronic renal disease in Kuwaiti nationals: a prospective study during the past 4 years.

Our study is a prospective one conducted at Al-Amiri Hospital and including all new cases of chronic renal disease (CRD) seen at the capital area of Kuwait between 1 January 1999 and 30 December 2003. Diagnosis of CRD was based on clinical, laboratory, and radiological features. Kidney biopsies were done when indicated. A total of 271 cases of chronic renal failure (CRF) were diagnosed, of whom 143 were women. The median age was 40 years (range, 5 to 80 years; mean +/- SD: 40 +/- 14). The most common cause of CRF was glomerulonephritis (32%), of which systemic lupus erythematosis and vasculitis constituted 5% and 4%, respectively. Diabetic glomerulosclerosis was the second leading cause of CRD (24%), followed by tubulointerstitial disease (11%) and nephroangiosclerosis (10%). Less frequent causes included renovascular/ischemic disease (6%), obstructive nephropathy (3%), and adult polycystic kidney disease (3%). One hundred and seven patients had 121 incidents of acute deterioration of underlying renal disease. This was mostly due to drugs (22%), infection (21%), and volume depletion (13%). Antiinflammatory drugs were the most common drugs (63%) responsible for the acute decline in renal function. By the end of the study, 18 (7%) patients died, 55 (20%) required maintenance dialysis, and 40 (15%) had received a kidney allograft. Diabetic patients did not differ from nondiabetic with regard mortality, although had more renal replacement therapy (p = .002). Using the Cox regression model, analysis of the relative risk factors likely to contribute to mortality, viz. age, gender, original kidney disease, fitness for transplantation, and mode of presentation, did not show significant factors except for less hazard to death in those diagnosed early with CRD (i.e., on routine testing; relative risk 0.06, p = .01). In conclusion, our study indicates that early diagnosis and management of CRD can improve the patient's quality of life and decrease the cost of frequent hospitalization, morbidity, and even mortality associated with end-stage renal disease.

Postmortem biopsies: the experience in Kuwait.

OBJECTIVE: To report our 4-year experience in postmortem needle biopsy of liver, heart, kidney and lung tissues when formal autopsy could not be performed. SUBJECTS AND METHODS: In the period from January 2000 to December 2003, postmortem biopsies were done at Al-Amiri Hospital, Kuwait, in 19 cases where the original diagnosis or cause of death was not clear. The procedure was performed by a dedicated trained medical team using a biopsy needle or limited incisions guided by the knowledge of the clinical presentation and results of laboratory and radiological investigations. RESULTS: The actual diagnosis was established in 8 cases by postmortem histological findings and corrected in another 9 cases. In the remaining 2 cases with systemic sepsis, autopsy only confirmed the antemortem clinical diagnosis. CONCLUSION: Our study shows that needle biopsy is an adequate technique for postmortem examination and should be considered as the minimum alternative to conventional autopsy.
