Μalakoplakia is a rare inflammatory condition of the urogenital tract. The most frequently affected organ is urinary bladder. This condition has features of a granulomatous inflammation, the pathogenesis of which is not well understood. In this study, we presented a case of urinary bladder malakoplakia associated with advanced obstructive uropathy and renal failure.
We report a case of membranoproliferative glomerulonephritis (MPGN) with IgMκ light chain deposits in a patient with chronic hepatitis C infection and simultaneous onset of monoclonal IgMκ gammopathy with concurrent small B-cell lymphoproliferative disease. The patient presented with hepatosplenomegaly and a uremic state that necessitated dialysis without any clinical signs of systemic disease apart from the chronic infection with hepatitis C virus. The diagnostic approach led to a renal biopsy that revealed MPGN with dominant IgMκ deposits and interstitium infiltration by the lymphoid cells. The bone marrow biopsy findings were consistent with splenic marginal zone lymphoma, a rare lymphoproliferative disorder with a rare association with MPGN. Our case indicates high diagnostic value of renal biopsy for rare lymphoplasmacytic neoplasms with renal dysfunction as their predominant clinical manifestation.
Conclusions: Advanced age, elevated ABP (correlated with severity and elevated PP), DM using Insulin, dyslipidemia, low educational level, specific occupation (maid and retired), direct relatives on dialysis and sedentary lifestyles, are important characteristics associated with sCKD. With these information we can focus our CKD screening in a better manner No conflict of interest
Background: Recombinant interferon β is now the mainstay of maintenance therapy for multiple sclerosis in many countries. Retinal lesions are rarely related with subcutaneous interferon β1α in multiple sclerosis. Interferon nephrotoxicity is also an extremely rare side effect. We report a case of interferon-associated retinopathy and nephropathy in a patient with multiple sclerosis receiving subcutaneous interferon β1α.Case report: A 42 years old Caucasian female with a history of multiple sclerosis on continuous treatment with interferon β1α, presented with anemia, thrombocytopenia, albuminouria, mild elevation of liver enzymes, renal impairment and sudden hypertension without visual disorders. Ocular fundus exam showed several retinal cotton wool spots indicating interferon-retinopathy and the drug was discontinued. Biochemical and immunological analyses were negative for autoimmune renal diseases. The retinopathy disappeared without specific therapy 2 months after discontinuing interferon β1α and kidney function restored. Interferon β1α resumed 16 weeks after stopping treatment due to multiple sclerosis relapse. On an iterative fundus exam 3 months after resumption of interferon β1α, no further cotton wool spots have recurred. 6 and 12 months later, with the patient on interferon β1α treatment, the ocular fundus was free of lesions and kidney function was within normal range.
Conclusions:In our patient, both complications resolved after drug cessation and the diagnosis of interferon β1α retinopathy and nephropathy was retained due to the lack of any other etiology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
