Abstract
Long-term inflammation and recurrent skin infection in recessive dystrophic epidermolysis bullosa (RDEB) are associated with the presence of immunoglobulin A (IgA)-containing immune complexes in the glomerulus. Only eight pediatric RDEB cases with IgA nephropathy (IgAN) have been documented in English-language literature. Most RDEB patients with IgAN progress to kidney failure within 5 years of diagnosis, indicating that these patients may require more intensive early treatment compared to those with primary IgAN. However, diagnosing IgAN in RDEB cases with severe cutaneous manifestations can be challenging. Herein, we report a rare case of nephropathy in an 11-year-old boy with severe RDEB and a frameshift mutation on the COL7A1 gene, which may manifest as kidney disorders. He presented with persistent hematuria and progressing proteinuria. A presumptive IgAN diagnosis was based on clinical features and increased IgA serum levels, as kidney biopsy was refused by his parents. Nephrotic-range proteinuria persisted despite initial steroid and lisinopril treatment. Monthly intravenous cyclophosphamide (IV CPA; 500 mg/m2) led to proteinuria remission and preservation of kidney function for 2 years posttreatment. We conclude that COL7A1 mutations may result in extracutaneous manifestations, including kidney disorders. The association between IgA-containing immune complex deposits in the glomerulus and recurrent skin infection in RDEB may indicate IgAN, particularly when kidney biopsy is infeasible due to severe skin manifestations. In our case, positive results with IV CPA suggest further investigation is needed to explore its potential role in non-rapidly progressing IgAN in children with RDEB.

Abstract
Since 1995, when we reported the case of a patient with glomerulonephritis with IgA deposition that occurred after a methicillin-resistant Staphylococcus aureus (MRSA) infection, many reports of MRSA infection-associated glomerulonephritis have accumulated. This disease is being systematized as Staphylococcus infection-associated glomerulonephritis (SAGN) in light of the apparent cause of infection, and as immunoglobulin A-dominant deposition infection-related glomerulonephritis (IgA-IRGN) in light of its histopathology. This glomerulonephritis usually presents as rapidly progressive glomerulonephritis or acute kidney injury with various degrees of proteinuria and microscopic hematuria along with an ongoing infection. Its renal pathology has shown several types of mesangial and/or endocapillary proliferative glomerulonephritis with various degrees of crescent formation and tubulointerstitial nephritis. IgA, IgG, and C3 staining in the mesangium and along the glomerular capillary walls have been observed on immunofluorescence examinations. A marked activation of T cells, an increase in specific variable regions of the T-cell receptor β-chain-positive cells, hypercytokinemia, and increased polyclonal immune complexes have also been observed in this glomerulonephritis. In the development of this disease, staphylococcal enterotoxin may be involved as a superantigen, but further investigations are needed to clarify the mechanisms underlying this disease. Here, we review 336 cases of IgA-IRGN and 218 cases of SAGN.

Abstract
For over a century, acute 'post-streptococcal glomerulonephritis' (APSGN) was the prototypical form of bacterial infection-associated glomerulonephritis, typically occurring after resolution of infection and a distinct infection-free latent period. Other less common forms of infection-associated glomerulonephritides resulted from persistent bacteraemia in association with subacute bacterial endocarditis and shunt nephritis. However, a major paradigm shift in the epidemiology and bacteriology of infection-associated glomerulonephritides has occurred over the past few decades. The incidence of APSGN has sharply declined in the Western world, whereas the number of Staphylococcus infection-associated glomerulonephritis (SAGN) cases increased owing to a surge in drug-resistant Staphylococcus aureus infections, both in the hospital and community settings. These Staphylococcus infections range from superficial skin infections to deep-seated invasive infections such as endocarditis, which is on the rise among young adults owing to the ongoing intravenous drug use epidemic. SAGN is markedly different from APSGN in terms of its demographic profile, temporal association with active infection and disease outcomes. The diagnosis and management of SAGN is challenging because of the lack of unique histological features, the frequently occult nature of the underlying infection and the older age and co-morbidities in the affected patients. The emergence of multi-drug-resistant bacterial strains further complicates patient treatment.

Abstract
BACKGROUND IgA-dominant infection-related glomerulonephritis (IgA-IRGN) is a unique form of IRGN, which needs to be distinguished from IgA nephropathy (IgAN). METHODS Thirteen patients with IgA-IRGN (IgA-IRGN group) and 122 with IgAN (IgAN group) were selected from 1788 patients who underwent kidney biopsy between 2000 and 2015 in Kitano Hospital. Data selected included clinical and serological parameters; light and electron microscope findings; immunofluorescence findings; and prognostic parameters like renal and overall survival and creatinine increase by > 50%. In addition, a 26-patient IgAN cohort (matching-IgAN), matching with IgA-IRGN group with respect to age, sex, estimated glomerular filtration rate (eGFR), and proteinuria was segregated for comparison. RESULTS Compared to IgAN group, IgA-IRGN group were older, had lower hemoglobin, higher CRP, lower eGFR, heavier proteinuria, lower serum albumin, and higher serum IgG and IgA levels (p < 0.05). Endocapillary hypercellularity, deposition of immune complexes along the glomerular capillary wall, and subendothelial and subepithelial electron dense deposits were more frequently observed (p < 0.05); and they were more susceptible to renal dysfunction and poorer prognosis. After propensity score-matching, serum albumin was significantly lower in the IgA-IRGN group. Significantly subendothelial and subepithelial deposits were frequently observed in this group. Matching-IgAN group showed relatively advanced sclerotic lesions with more global sclerosis and fibrous crescent. CONCLUSION Local inflammation involved glomerular capillary wall in IgA-IRGN, in contrast to relatively chronic and sclerotic renal lesion in IgAN, might result in poorer prognosis in former, even under indistinguishable condition of deteriorated renal function and proteinuria.

Anterior Cruciate Ligament Graft Removal Versus Retention in the Setting of Septic Arthritis After Reconstruction: A Systematic Review and Expected Value Decision Analysis. Arthroscopy 2018; 34:967-975. [PMID: 29122433 DOI: 10.1016/j.arthro.2017.08.246] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2017] [Revised: 08/07/2017] [Accepted: 08/07/2017] [Indexed: 02/02/2023]
Abstract
PURPOSE To provide further guidance on the optimal decision between anterior cruciate ligament (ACL) graft removal versus retention in the setting of septic arthritis following reconstruction using an expected value decision analysis. METHODS A systematic review and expected value decision analysis and sensitivity analyses were performed to quantify the clinical decision. A decision tree was created with 5 outcomes of interest: nonoperative complications, revision surgery, early reoperation, late reoperation, and "well." Pooled probabilities of each outcome were generated through a systematic literature review. We included only peer-reviewed studies, published in English, with at least 6 months of follow-up. One hundred randomly selected volunteers were given descriptions of the clinical scenario, the 2 treatment options, and outcomes of interest. Patients younger than 18 and older than 50 years and those previously treated for either ACL injury or septic arthritis, or both, were excluded from the analysis to minimize bias. These hypothetical patients indicated preferences for each outcome on a visual analog scale and responses were averaged to generate overall "utility values." Fold-back analysis summed products of pooled outcomes probabilities with respective averaged utility values. The resulting overall expected values for graft removal and debridement were compared, with the highest expected value considered to be superior. We then performed 1-way sensitivity analyses to mitigate sample bias. RESULTS Fold-back analysis revealed graft removal to be strongly favored over retention, with overall expected values of 17.2 and 8.64, respectively. The most important contributor to the difference in overall expected values was late reoperation (8.59 vs 2.50 for removal and retention, respectively). Despite adjustments made to the rates of revision and early reoperation during the 1-way sensitivity analyses, graft removal remained the optimal strategy. CONCLUSIONS This expected value decision analysis revealed that ACL graft removal was strongly favored by patients over graft retention in the setting of postoperative septic arthritis when consideration was given to the probabilities of wellness, nonoperative complications, revision surgery, early reoperation, and late reoperation. Sensitivity analysis revealed that although variation in rates of other outcomes did not impact this preference, the rate of late reoperation had a substantial impact. Only a sizable increase in the probability of late reoperation (from 0% to 60%) after graft removal would cause potential patients to favor graft retention. LEVEL OF EVIDENCE Level IV, systematic review and decision analysis.

Abstract
BACKGROUNDS IgA-dominant infection-associated glomerulonephritis (IgA-dominant IAGN) is a unique form of glomerulonephritis. There are numerous case reports in the literature. However, the risk factors, treatment approach, and outcomes of the disease are not clearly characterized. METHODS We completed a pooled analysis based on published literature. Clinical features, laboratory findings, and histopathological changes were analyzed. A logistic regression model was employed to identify the determinants of disease outcome, for example, end-stage renal disease (ESRD) or death. RESULTS Seventy-eight patients with IgA-dominant IAGN from 28 reports were analyzed. All of these patients showed granular IgA deposits predominantly along the glomerular peripheral capillary walls using immunofluorescence and majority showed subepithelial 'hump-shaped' electron-dense deposits using electron microscopy. The majority of patients had hematuria (76/78), proteinuria (75/78), acute kidney injury (AKI) (66/78) and hypocomplementemia (43/75) without a previous history of renal disease. All of the patients had clinical infections at the time of presentation. Skin infections (19/78) and visceral abscesses (15/78) were frequently encountered, and staphylococcus was the most common pathogen. After treatment with antibiotics and/or supportive therapy, the renal function of 42 patients (54.5%) improved, 9 patients (11.7%) had persistent renal dysfunction, 15 patients (19.5%) progressed to ESRD, and 11 patients (14.3%) died. A multivariate regression analysis revealed that age (odds ratio [OR], 30.71; 95% confidence interval [CI], 2.53-373.07; p = 0.007) and diabetes mellitus (DM) (OR, 16.65; 95% CI, 1.18-235.84; p = 0.038) were independent risk factors for ESRD or death. CONCLUSIONS IgA-dominant IAGN has unique clinicopathological manifestations and treatment responses. Age and DM are independent risk factors associated with an unfavorable prognosis for IgA-dominant IAGN.

Abstract
PURPOSE Septic arthritis after an ACL reconstruction is a rare but serious complication. Functional outcomes of these patients have not been studied in depth in large series. The aim of this study was to determine the prevalence and management of knee joint infection following ACL reconstruction and to assess the functional outcomes. METHODS A retrospective assessment of knee joint infections occurring after arthroscopically assisted ACL reconstructions done from 2006 to 2009 in two hospitals by the same surgical team is presented. Patients with signs and symptoms of joint infection along with blood and synovial effusion laboratory parameters suggestive of infection were considered as septic arthritis. All the patients were treated with antibiotic therapy according to antibiotic sensitivity and had at least one arthroscopic lavage. Final outcomes were assessed and compared with a control group using the KT-1000 arthrometer, functional testing and radiological examination. RESULTS Fifteen (1.8 %) out of 810 patients included in the study were considered as a joint infection. Microbiology showed that coagulase-negative Staphylococcus was present in 10 patients, Staphylococcus Aureus in three patients (2 MSSA and 1 MRSA) and Propinebacterium sp. in one patient. In one patient, the micro-organism was unknown. At a mean follow-up of 39.3 ± 13 months, the Lysholm score was 77.7 ± 15.3, the IKDC score was 70.4 ± 19.5, and the KT-1000 compared to the non-injured contralateral knee showed a mean difference of 1.3 ± 2 mm. Functional outcomes in the control group were slightly better than those obtained in the infected group (Lysholm score; 90.7 ± 9.4, p = 0.007. IKDC score; 86.6 ± 6.8, p = 0.004). All but one patient retained their reconstructed ACL. CONCLUSIONS The prevalence of septic arthritis after an ACL reconstruction in this series was 1.8 %. Arthroscopic lavages along with antibiotic treatment led us to preserve all but one graft. Functional outcomes in the infected patients were not as good as those obtained in patients without infection.

Abstract
Background and objectives. The mesangial deposition of IgA is rarely described with proliferative glomerulonephritis associated with Staphylococcus infection. Recently, this association has been increasingly recognized possibly due to the increased rate of Staphylococcus infection. Design setting, participants and measurements. We report two cases of methicillin-sensitive Staphylococcus aureus bacteremia associated with acute proliferative glomerulonephritis with dominant mesangial deposit of IgA. We searched MEDLINE (1960–2009) for similar reports. We pooled individual patient data and reported descriptive statistics of all published cases. Results. Forty-six cases were included in the final analysis. The mean age of presentation was 59, with a male predominance (84%). Clinical presentation was notable for rapidly progressive glomerulonephritis with nephrotic-range proteinuria and normal complement levels in 52 and 72%, respectively. Methicillin-resistant S. aureus (68%) was the most common pathogen isolated with a latent period ranging from 1 to 16 weeks. Diffuse mesangial proliferation was commonly found with crescentic lesions noted in 35% of the cases. Antimicrobial treatment was associated with renal recovery in 58% of the cases. Need for renal replacement therapy was significantly associated with pre-existing diabetes, hypertension and interstitial fibrosis seen on kidney biopsy. Conclusions. IgA-dominant post-Staphylococcus glomerulonephritis is a rare clinical entity with certain unique clinical and morphologic features. It is difficult to differentiate from primary IgA nephropathy in cases where the infection is not apparent. An acute onset of rapidly progressive glomerulonephritis, with normal complement levels and deposition of mesangial IgA in an elderly patient should raise suspicion for this rare form of glomerulonephritis.

Abstract
BACKGROUND Septic arthritis after arthroscopic anterior cruciate ligament reconstruction is a rare complication. In the literature, several different managements are proposed. HYPOTHESIS The graft can be retained during treatment of a septic arthritis after anterior cruciate ligament reconstruction. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective analysis of knee joint infections occurring after arthroscopically assisted anterior cruciate ligament reconstructions was conducted. Fifteen patients were treated for postoperative septic arthritis of the knee after anterior cruciate ligament reconstruction between 1996 and 2005. All patients underwent an urgent extensive arthroscopic debridement (wash-out and synovectomy) and parenteral antibiotics and oral antibiotics subsequently. Repetitive wash-outs were performed if necessary. The average time at follow-up for our series was 58 months (range, 9-99 months). RESULTS Only 1 graft was removed during debridement because it was nonfunctional. All other patients retained their anterior cruciate ligament reconstruction. There was no reinfection. There were 2 traumatic reruptures. We evaluated 11 patients: in 6 patients the Lachman test showed a translation of more than 3 mm, but all patients had a firm endpoint and there was no subjective instability. Early signs of radiological degeneration were seen in 3 patients. The value for the Lysholm knee scoring scale was 83, on average, ranging from 57 to 100. Regarding the International Knee Documentation Committee score, 2 patients had a final evaluation of normal, 7 patients nearly normal, and 2 patients abnormal. CONCLUSION The graft can be retained during treatment of septic arthritis after anterior cruciate ligament reconstruction.

Abstract
A small but important proportion of patients with epidermolysis bullosa (EB) may develop significant renal and urological complications which can have a major impact on their morbidity and mortality. During the last 10 years, five of a large group of children with EB under our care, with either dystrophic or junctional types of disease, experienced major nephro-urological complications. Two patients with recessive dystrophic EB (REDB) developed macroscopic haematuria - one had renal failure and underwent a renal biopsy showing IgA nephropathy. A third patient with RDEB also developed renal failure and his biopsy demonstrated postinfectious glomerulonephritis/type III membranoproliferative (mesangiocapillary) glomerulonephritis. Both patients with renal failure underwent peritoneal dialysis. Two patients with junctional EB developed obstructive uropathies, which required bladder reconstruction and the fashioning of a Mitrofanoff channel in one.

Abstract
An exceptional case report of community-acquired, disseminated infection caused by a methicillin-resistant Staphylococcus aureus strain, responsible for pneumonia, sepsis, and scattered septic embolism, and accompanied by diffuse polyvisceritis and thrombophlebitis as signs of an overwhelming extensive activation of the immune system, is reported and discussed on the grounds of the most recent evidence in literature. The striking features of a severe, multiresistant S. aureus polyvisceral disease associated with multiple immune-mediated focal manifestations are in contrast with the community-acquired origin of infection and the apparent absence of supporting factors for both antimicrobial resistance and the unexpected, exaggerated immune activation occurred in an otherwise healthy man. The extensive immune activation status (as demonstrated by a proportionally maintained absolute lymphocyte cont and a T-cell subset study pointing out an increased quote of CD4+, CD34+, and CD4-CD8- cells, compared with a proportional decrease of CD8+ T-lymphocytes) probably had a prominent role in prompting several focal clinical features of our patient, which apparently were not directly related to bacterial invasion, such as the polyvisceritis, the massive pleuric and pericardial effusion, the myocarditis-pericarditis, and the thrombophlebitis occurring in multiple and remote body sites, as compared with to the initial respiratory localization. This case report raises multiple questions regarding the epidemiology, pathogenesis, clinical manifestations, and management of complicated S. aureus infection, including the role of novel antimicrobial agents and corticosteroids.
