POS-235 SPONTANEOUS RECOVERY IN CRESCENTIC FIBRILLARY GLOMERULONEPHRITIS

“Tennis and golfer’s elbow” are common pathologies due to overload of forearm extensors and flexors, and actually occur mostly outside tennis and golf sports. Several differential diagnoses of medial and lateral epicondylitis have to be excluded as there are a number of other conditions with similar clinical symptoms. The high rate of spontaneous recovery has to be considered in treatment. Evidence based conservative treatment comprises excentric physiotherapy, local injections, and physical methods. Surgery is reserved for patients with persistence of symptoms for more than one year despite non-surgical treatment.

Objectives: Patients with vocal cord paralysis can experience feeding, respiratory, and vocal problems leading to disability and decreased quality of life. Current evidence suggests waiting a period of 12 months for spontaneous recovery before permanent interventions. This study aims to determine the time to recover spontaneously and vocal cord movement in a pediatric population and create a model for evidence-based patient counseling. Study Design: Retrospective longitudinal cohort study. Methods: The report is a single institution longitudinal study on vocal cord paralysis recovery. Patients were categorized based on spontaneous recovery with vocal cord movement or no recovery. Recovery rates were determined using the Kaplan-Meier method. Results: Of 158 cases of vocal cord paralysis over a 4-year period, 36 had spontaneous recovery with symptom improvement and motion return. The average recovery was 8.8 months for those who recovered, and 78% recovered within 9 months. Two groups emerged from the data: an early recovery group with spontaneous recovery before 12 months and a late recovery group after 12 months. Children with dysphonia and paralysis due to cardiac surgery were less likely to recover, and children with aspiration were more likely to recover. Children with gastrointestinal comorbidities were less likely to recover; however, those who did recover were more likely to have recovered after 12 months. Based on our model, there is about a 3% chance of recovery between 9 and 12 months. Conclusions: Patients should be counseled about earlier interventions. Waiting the conventional 12 months for only a 3% chance of spontaneous recovery without intervention or laryngeal EMG may not be the preferred option for some patients and their families.

Immunotactoid Glomerulonephritis

Fibrillary and immunotactoid glomerulonephritis are infrequent causes of primary nephrotic range proteinuria and are poorly understood. Recent significant developments include the discovery of DNA JB9 antigen in fibrillary glomerulonephritis. Here, we present a case of a middle-aged woman who presented with nephrotic range proteinuria, hematuria, and normal renal function. Renal biopsy revealed fibrils that were randomly arranged on electron microscopy. They were of small size and congo red negative similar to the ones found in fibrillary glomerulonephritis, but were also DNA JB 9 negative, and had a hollow core like in immunotactoid glomerulopathy. Though we try to classify these conditions into either immunotactoid glomerulonephropathy (ITGN) or fibrillary glomerulonephritis (FGN), there are scenarios such as this case where it does not fit into either and is probably an overlap or intermediate variant of these two conditions. Pathological features of these glomerulonephrites are discussed together with their clinical implications, treatment choices, and diagnostic importance.

Abstract Background Coexistence of fibrillary glomerulonephritis (FGN) and immunoglobulin A (IgA) nephropathy (IgAN) in the same kidney biopsy (FGN–IgAN) is rare, and the clinicopathologic characteristics and outcome of this dual glomerulopathy are unknown. Methods In this study, 20 patients with FGN–IgAN were studied and their characteristics were compared with 40 FGN and 40 IgAN control patients. Results Concurrent IgAN was present in 1.8% of 847 consecutive FGN cases and was the second most common concurrent glomerulopathy after diabetic nephropathy. FGN–IgAN patients were overwhelmingly White (94%) and contrary to FGN patients were predominantly (60%) males. Compared with IgAN patients, FGN–IgAN patients were older, had higher proteinuria, a higher incidence of renal insufficiency, and a lower incidence of microhematuria and gross hematuria at diagnosis. Six (30%) patients had malignancy, autoimmune disease or hepatitis C infection, but none had a secondary cause of IgAN or clinical features of Henoch–Schonlein purpura. Histologically, all cases exhibited smudgy glomerular staining for immunoglobulin G and DnaJ homolog subfamily B member 9 (DNAJB9) with corresponding fibrillary deposits and granular mesangial staining for IgA with corresponding mesangial granular electron-dense deposits. On follow-up (median 27 months), 10 of 18 (56%) FGN–IgAN patients progressed to end-stage kidney disease (ESKD), including 5 who subsequently died. Serum creatinine at diagnosis was a poor predictor of renal survival. The proportion of patients reaching ESKD or died was higher in FGN–IgAN than in IgAN. The median Kaplan–Meier ESKD-free survival time was 44 months for FGN–IgAN, which was shorter than IgAN (unable to compute, P = 0.013) and FGN (107 months, P = 0.048). Conclusions FGN–IgAN is very rare, with clinical presentation and demographics closer to FGN than IgAN. Prognosis is guarded with a median renal survival of 3.6 years. The diagnosis of this dual glomerulopathy requires careful evaluation of immunofluorescence findings, and electron microscopy or DNAJB9 immunohistochemistry.
