A 38-year-old female was admitted to our hospital because she was suffered from severe dyspnea on effort. She had a history of nasal bleeding, endocarditis, fever, proteinuria, and alopecia at the age of 16, and was diagnosed as SLE. She was suffered from recurrent cerebral infarctions at the age of 35 and 38, and then mitral regurgitation was pointed out. Preoperative examination revealed non-active phase of SLE and UCG showed massive mitral regurgitation. Operative findings showed thrombosed verrucca circumferentially on the mitral valve. Mitral valve replacement (B-S #27) was done with using a felt strip in order to reinforce the mitral annular tissues. Histological findings of the verrucca showed Libman-Sacks endocarditis. Postoperative course was uneventful. Surgical treatment for Libman-Sacks endocarditis is extremely rare.

A 65-year-old woman presented rapidly progressive glomerulonephritis with purpura and mitral insufficiency. Blood cultures grew Streptococcus mitis. By light microscopy, the renal biopsy revealed necrotizing glomerulonephritis 56% associated with cellular crescents and tubulointerstitial changes. By immunofluorescence, deposits of IgM and C3 were found to be present in the mesangium. Electron-microscopic study showed subendothelial and intramembranous deposits. Treatment with antibiotics alone resulted in renal recovery with disappearance of proteinuria, circulating immune complexes and cryoglobulinemia. A 2nd renal biopsy, performed after 3 months, showed segmental sclerosis and tubulointerstitial lesions. Eight months after the first hospitalization, cardiac insufficiency occurred. Four years later, a valve replacement was performed. No abnormal serum creatinine, serum creatinine clearance or urinalysis levels were present. These data suggest that rapidly progressive glomerulonephritis associated with bacterial endocarditis may be treated by antibiotics alone and result in normal and stable renal function.

During an epidemic of acute glomerulonephritis (AGN) 15 patients were studied by M-mode, cross-sectional, and Doppler echocardiography. All 15 patients had the classical signs of the disease including hematuria, proteinuria, edema, and consistent laboratory findings. There were 10 boys and five girls with a mean age of 8 years. Ten of the 15 patients had an enlarged left atrium and five of these 10 also had transient mild to moderate mitral regurgitation. In the five patients with mitral regurgitation the ratio of left atrium/aorta was 1.48; in the five patients with an enlarged left atria without evidence of mitral regurgitation the left atrium/aorta ratio was 1.34. All the patients had normal left ventricular dimensions, as well as ejection and shortening fractions. The findings of left atrial enlargement and mitral regurgitation disappeared gradually in all patients within 3 months. There was no correlation between the level of systemic blood pressure and the development of mitral regurgitation. A possible cause for these changes is fluid overload in the oliguric phase of the acute glomerulonephritis. The changes are transient and probably functional. There was no significant mitral valve or left atrial anomaly 3 and 6 months after hospital discharge.

Cardiac involvement, evaluated by echo-doppler-cardiography, occurred in 41 of 50 (82%) patients with systemic lupus erythematosus (SLE). Valvular pathology with aortic cusp sclerosis was the most prevalent finding irrespective of age. This finding, suggestive of atherosclerotic heart disease, was supported by increased levels of cholesterol and triglycerides in these patients. There was no significant increase in Lp(a) in the whole patient group, but Lp(a) was raised in patients with proteinuria. Forty percent of the SLE patients had pericarditis. Twelve patients with hypertension and/or mitral regurgitation had increased dimensions of left ventricle, left atrium or interventricular septum while 15 of 50 patients had isolated increase of these parameters. Localized hypokinesia was found in nine patients. Reduced cardiac index was found in five patients with SLE. There was no association between valvular disease, increased pulmonary artery pressure, and anticardiolipin antibodies.

Secondary amyloidosis (AA amyloidosis) has rarely been described in patients with systemic lupus erythematosus (SLE). We, herein, present a 56-year-old female patient, who developed AA amyloidosis following a 22-year history of SLE. She developed severe mitral regurgitation complicated with chordae tendinea rupture that led to acute congestive heart failure and went on a mitral valve replacement, where no flare symptoms of SLE were present. Three months after the operation, she presented with a nephrotic-range proteinuria, acute renal failure, and severe sepsis. She was found to have new vegetations on replaced valve and multi-organ failure caused her death. Re-evaluation of the excised mitral valve revealed AA amyloid deposition. Post-mortem biopsies from the kidney and bone marrow also revealed secondary amyloidosis.

A severely ill 65-year-old man presented with symptoms of shortness of breath, edema and vasculitidic purpura over his lower extremities. He had severe mitral regurgitation which had not been surgically treated. Hematologic examination demonstrated leukocytosis with profound anemia. Other blood tests revealed impaired renal function, hypoalbuminemia, hypocomplementemia and mixed-type cryoglobulinemia. Urinalysis showed proteinuria, hematuria and pyuria, typical of a nephritic sediment. Renal biopsy indicated diffuse proliferative glomerulonephritis and a "full house" deposition in immunofluorescence study (positive for C3, C4, C1q, IgG, IgA and IgM), resembling the pathologic findings in class IV lupus nephritis. Although subacute bacterial endocarditis was initially suspected owing to a history of a predisposing valvular heart disease, probable vegetation shown by cardiac sonography and a clinical picture suggestive of a chronic infection, it was thought unlikely due to the entire afebrile course and initial sterile blood cultures. However, the blood cultures repeated 2 weeks after admission grew 3 sets of viridans streptococci. Following a course of penicillin and gentamicin treatment, his renal function, anemia and abnormal urine sediments improved gradually. Diffuse proliferative glomerulonephritis is well known to occur in infective endocarditis. However, the "full house" immunostaining in immunofluorescence study has never been reported. This case adds a new entity to the differential diagnosis of "full house" immune complex-related glomerulonephritis and exemplifies the need to maintain a high index of suspicion for underlying infectious disorders when facing glomerulonephritic or vasculitic syndrome.

We report a case of IgA-dominant postinfectious glomerulonephritis in a 49-year-old man presenting with acute kidney injury, nephrotic range proteinuria and hematuria. He suffered from ischemic heart disease, cardiac insufficiency, mitral regurgitation, tricuspid insufficiency, septal aneurysm and hypertension. Renal biopsy revealed segmental and focal endocapillary and mesangial hypercellularity, and thickening of the glomerular capillary wall. Immunofluorescence showed co-dominant strong coarse granular immunostaining of IgA, IgG and C3 mainly along the glomerular capillary wall. On electron microscopy some large subepithelial hump-shaped deposits were present. In summary, this case demonstrates the presence of a broad spectrum of glomerular histological findings in postinfectious glomerulonephritis.

Amyloidosis is a conglomeration of diseases due to production and deposition of amyloid, a proteinaceous substance, into organs, tissues, nerves and other places in the body affecting their normal function. This case report is of a 65 year old gentleman, resident of Bihar admitted with a short history of two months. He came with chief complaints of swelling in both lower limbs associated with heaviness in legs, shortness of breath, dizziness, fatigue and passage of frothy urine for two months. He was investigated and found to have proteinuria, low voltage ECG, Echocardiography showed left ventricular hypertrophy, diastolic dysfunction, mitral regurgitation. Cardiac MRI showed dilated cardiomyopathy due to amyloidosis.
