Özet
Multipl miyelom (MM); anemi, tekrarlayan enfeksiyonlar, serum ve/veya idrarda monoklonal protein artışı, osteolitik kemik lezyonları, hiperkalsemi ve böbrek yetmezliği ile karakterize neoplastik bir plazma hücre diskrezisidir. MM ilişkili böbrek yetmezliği erken mortaliteye neden olan önemli bir prognostik faktördür ve MM’da böbrek hastalığı sıklığı tanıma bağlı olarak %20-50 arasında değişmektedir. Bu çalışmada, Necmettin Erbakan Üniversitesi, Meram Tıp Fakültesi, Hematoloji ve Nefroloji Kliniklerine başvuran MM hastalarında, nefropati sıklığı ve ilişkili faktörler araştırıldı. Son beş yıl içerisinde hastanemizde MM tanısı ile takip edilen toplam 104 hasta (K/E: 55/49) retrospektif olarak incelendi. Hastaların ortalama takip süresİ 29ay, yaş ortalaması 6410.6 yıldı. Takip süresince hastaların %30.8’i ölmüş, %58’i ise halen yaşamaktaydı. Hastaların %10.6’sının ise akıbeti öğrenilemedi. Kreatinin değeri 2 mg/dL olan hastalar miyelom nefropatili olarak kabul edildi. Başlangıç tedavisi olarak vinkristin-adriyamisin-deksametazon veya melfelan-metilprednizolon (65 yaş hastalar için) verilmişti. SPSS 15.0 programı ile istatistiksel analizler yapıldı. Çalışmaya katılan 104 hastanın %31.7’sinde (n33), miyeloma bağlı böbrek yetmezliği tespit edildi. Serum kreatinini 2 mg/dL olanlarda hipovolemi ve oligüri oranları daha yüksek bulundu (p0.001). Miyeloma bağlı böbrek yetmezliği olanların ortalama ürik asit (p0.002) ve kalsiyum (p0.037) değerleri, böbrek yetmezliği olmayanlardan yüksekti. Başlangıçta 31 hastada (%29.8) hemodiyaliz (HD) ihtiyacı varken bunların 19’unda (diyaliz yapılan hastaların %61.2’si, tüm hastaların %18.2’si) HD kalıcı oldu. Böbrek tutulumu olan MM hastalarında mortalite %42.4 iken böbrek tutulumu olmayanlarda %25.3 oranındaydı (p0.034). Multipl miyelomda böbrek yetmezliği kötü prognositik belirteçler arasında yer almaktadır. Hastaların yaklaşık üçte birinde miyeloma bağlı böbrek hastalığı saptandı. Böbrek yetmezliği, esas olarak monoklonal hafif zincir nefropatisine bağlı olarak gelişse de hipovolemi gibi geri dönüşümlü nedenlerin dikkatli değerlendirilmesi ve böbrek yetmezliği olan grupta artmış mortalite riski nedeniyle, MM’da bu alt gruba özellikle dikkat edilmesi gerektiğini düşünmekteyiz.
Multiple myelom (MM) is a plasma cell malignancy and is characterized by anemia, recurrent infections, serum and/or urine monoclonal protein, osteolytic bone lesions, hypercalcemia and renal failure . The prevalence of nephropathy varies between 20 and 50% in MM. In this study, the prevalence of nephropathy and related factors were aimed to investigate in MM patients who admitted to the Hematology and Nephrology clinics of Meram Faculty of Medicine, Necmettin Erbakan University. A total of 104 MM patients (F/M: 55/49) were retrospectively examined who were administered in the last five years. The mean follow up duration was 29 months. The mean age was 6410.6 years. During the follow-up period, 30.8% of our patients died and 58% were still alive. The fate of the 10.6% of the patients could not be learned. Patients with serum creatinine 2 mg/dL were considered as patients with nephropathy. The vincristine-adriamycin-dexamethasone or melfelan -methylprednisolone (for patients 65 years) were administered as initial therapy. Statistical analysis was performed with SPSS 15.0. Renal involvements were observed in 33 patients (31.7%). Hyperuricemia (p0. 002), hypercalcemia (p0.037), hypovolemia (p0 .001) and oliguria (p0.001) were found to be higher in patients with creatinine 2 mg/dL. In 31 patients (29.8%), hemodialysis (HD) treatment was required, 19 of these (61.2% of HD patients, 18.2% of all patients) were treated with HD permanently. Mortality rates were found as %42 in patients with nephropathy and %25.3 without nephropathy (p0.034). Renal failure is a poor prognostic marker in multiple myeloma. In this study one-third of MM patients had nephropathy requiring HD. Although renal insufficiency is mainly due to monoclonal light chain nephropathy, reversible causes such as hypovolaemia should be carefully evaluated. We think that particular attention should be paid to this group because of the increased risk of mortality.
