    Full Text Available Crystal-induced acute kidney injury (AKI is caused by the intratubular precipitation of crystals, which results in obstruction and kidney injury. Ciprofloxacin, a commonly used antibiotic, causes AKI secondary to immune-mediated interstitial injury. Rare mechanisms of ciprofloxacin-induced renal injury include crystalluria, rhabdomyolysis, and granulomatous interstitial nephritis. Clinical and experimental studies have suggested that crystalluria and crystal nephropathy due to ciprofloxacin occur in alkaline urine. Preexisting kidney function impairment, high dose of the medication, and advanced age predispose to this complication. We report a case of ciprofloxacin-induced crystal nephropathy and granulomatous interstitial nephritis in a young patient with no other predisposing factors. The patient responded to conservative treatment without the need for glucocorticoids.

    Full Text Available Granulomatous interstitial nephritis (GIN is a rare condition. Drugs, infections, immune processes, and foreign body reaction are the main causes. We identified a total of 14 patients with GIN during a period of 13 years in 2798 renal biopsies. There were 8 males and 6 females in the age range of 20-70 (mean 35 ± 12 years. The serum creatinine at presentation was 6.7 ± 3.8 (range: 2.3-14.7 mg/dl. In nine patients tuberculosis was the causative agent. Drugs (n = 2 and Wegener′s granulomatosis (n = 1 were other etiologies. Systemic lupus erythematosis (SLE and Immunoglobulin A nephropathy (IgAN were seen in one patient each. Patients with tuberculosis were treated with antituberculous therapy and three of them improved. Four out of six patients who required dialysis at presentation remained dialysis dependent, one of whom underwent renal transplantation. Two patients progressed to end stage renal disease after 7 years and 9 years each. The patients with drug induced GIN had improvement in renal function after prednisolone treatment. Patients with SLE, and Wegener′s granulomatosis responded to immunosuppression. Patient with IgAN was on conservative management. Finally, six patients were on conservative management for chronic renal failure.

    Among the various renal manifestations of sarcoidosis, granulomatous inflammation confined to the tubulointerstitial compartment is the most commonly reported finding. We present the case of a 66-year-old man with acute kidney injury, hypercalcemia, mild restrictive pulmonary disease, and neurologic signs of parietal lobe dysfunction. Kidney biopsy showed diffuse interstitial inflammation with noncaseating granulomas that exhibited the unusual feature of infiltrating the walls of small arteries with destruction of the elastic lamina, consistent with granulomatous vasculitis. The findings of granulomatous interstitial nephritis on kidney biopsy, hypercalcemia, and possible cerebral and pulmonary involvement in the absence of other infectious, drug-induced, or autoimmune causes of granulomatous disease established the diagnosis of sarcoidosis. Pulse methylprednisolone followed by maintenance prednisone therapy led to improvement in kidney function, hypercalcemia, and neurologic symptoms. Vasculocentric granulomatous interstitial nephritis with granulomatous vasculitis is a rare and under-recognized manifestation of renal sarcoidosis. Copyright © 2012 National Kidney Foundation, Inc.

    Full Text Available Sarcoidosis is an inflammatory disease that affects mostly the lungs and lymph glands. Renal involvement is rare and especially vasculitis. We report a case who presented an acute kidney failure and had sarcoidosis with vasculitis and nodular splenic involvement. A 35-year-old woman presenting a Lofgren syndrome was hospitalized for acute renal failure with cervical lymphadenopathy without other clinical findings. Laboratory data disclosed elevated angiotensin converting enzyme serum level. Abdominal ultrasound showed a multinodular spleen. Renal histology revealed granulomatous interstitial nephritis with necrotizing vasculitis. Outcome was favorable after the institution of high dose corticosteroids along with cyclophosphamide. Renal involvement is rare in sarcoidosis. However, the diagnostic delay should be avoided to improve the outcome.

    Full Text Available We report the case of a 42 years old male patient suffering from skin changes , which appeared in the last 7-8 years.  Two biopsies were performed during the evolution of the lesion. Both showed similar findings that consisted in a busy dermis with interstitial, superficial and deep infiltrates of lymphocytes and histiocytes dispersed among collagen bundles, with variable numbers of neutrophils scattered throughout. Some histiocytes were clustered in poorly formed granuloma that included rare giant cells, with discrete Palisades and piecemeal collagen degeneration, but without mucin deposition or frank necrobiosis of collagen. The clinical and histologic findings were supportive for interstitial granulomatous dermatitis. Interstitial granulomatous dermatitis (IGD is a poorly understood entity that was regarded by many as belonging to the same spectrum of disease or even synonym with palisaded and neutrophilic granulomatous dermatitis (PNGD. Although IGD and PNGD were usually related to connective tissue disease, mostly rheumatoid arthritis, some patients with typical histologic findings of IGD never develop autoimmune disorders, but they have different underlying conditions, such as metabolic diseases, lymphoproliferative disorders or other malignant tumours. These observations indicate that IGD and PNGD are different disorders with similar manifestations.

    Full Text Available The First Emperor of China (Qin Shi Huang: 259–210 BCE would have been interested in interstitial nephritis. He might conceivably be fascinated to know that consumption of mercury elixir, instead of giving him immortality, might have shortened his life by giving him interstitial nephritis. In the Balkan region of Eastern Europe, clustering of a peculiar interstitial nephritis is prevalent. One environmental risk contributing to Balkan endemic nephritis is aristolochic acid contamination of cooking flour, drinking water, and herbal medicine. In addition, the popular use of nonprescription Chinese weight reduction herbs and public unawareness of the consequential aristolochic acid nephropathy has become a worldwide problem. Finally, the mighty Romans of antiquity lost their empire, arguably due to lead in their wine containers, lead water pipes, and lead cooking utensils. In modern times, lead paint has become universally banned, which has resulted in a reduction of lead-induced interstitial nephritis. In recent decades, bisphenol A (BPA has been identified as a new environmental risk. BPA is in the plastic coating of food and beverage containers to prevent corrosion. BPA is so ubiquitous that urinary BPA and proteinuria are present in a high percentage of the population. BPA-induced kidney injury and other health concerns have led certain countries to ban BPA. Now, BPA-free containers are being introduced with great fanfare by manufacturers, but safety issues on all plastic products remain. It begs the question whether “plastics” of today take the place of “lead” in ancient Rome. This is a challenging question without an answer at this point.

  10. Acute interstitial nephritis induced by Dioscorea quinqueloba

    2014-01-01

    Background The use of herbal medicine may be a risk factor for the development of kidney injury, as it has been reported to cause various renal syndromes. Dioscorea quinqueloba is a medicinal herb that is used as an alternative therapy for cardiovascular disease and various medical conditions. Case presentation A 52-year-old man was admitted with complaints of skin rash and burning sensation. He had ingested a raw extract of D. quinqueloba as a traditional remedy. Laboratory tests revealed the following values: absolute eosinophil count, 900/mm3; serum creatinine level, 2.7 mg/dL; and blood urea nitrogen, 33.0 mg/dL. The immunoglobulin E level was markedly increased at 1320.0 IU/mL. Urinalysis revealed a fractional excretion of sodium of 3.77%, protein 1+, and blood 3+. Histological examination of the renal biopsy specimen showed a diffusely edematous interstitium with infiltrates composed of eosinophils, lymphocytes, and neutrophils. Conclusion Here, we present the first reported case of biopsy-proven acute interstitial nephritis following ingestion of D. quinqueloba associated with skin rash, eosinophilia, and increased plasma immunoglobulin E level.

    We report an atypical occurrence of invasive Strongyloides stercoralis infection of the stomach mucosa in an elderly female patient from Bangka Island, northwestern Indonesia. The patient presented with severe epigastric pain, edema of the legs, proteinuria and severe hypoalbuminemia. Gastric and duodenal biopsies found eggs, larval and adult forms present in the superficial mucosa with mild inflammation. The Harada-Mori filter paper culture technique revealed S. stercoralis filariform larvae and free-living adult worms, corroborating the diagnosis. The infection was associated with acute interstitial nephritis. The patient showed rapid and dramatic improvement after treatment with mebendazole.

    Full Text Available Proton pump inhibitors (PPI are commonly prescribed for dyspepsia and acid peptic disease. Acute interstitial nephritis (AIN is an uncommon though important side-effect of these classes of drugs. We describe four cases: three females and one male. PPIs implicated were pantoprazole in two, omeprazole and esomeprazole in one each. AIN developed after an average period of 4 weeks of drug therapy. The symptoms were vomiting, loin pain, and oliguria. Minimal proteinuria with pyuria were seen and the mean serum creatinine was 4.95 ± 4 mg/dl. Two patients required hemodialysis. Renal biopsy showed interstitial mononuclear, plasma cell and eosinophilic infiltrates in all cases. PPI was stopped and steroids were started in all. Renal recovery was total in two and partial in two. A high index of suspicion is required to diagnose PPI induced AIN. Renal biopsy for confirmation followed up by prompt steroid therapy results in renal functional improvement.

    Full Text Available Abstract Drug-induced acute interstitial nephritis (AIN represents a growing cause of renal failure in current medical practice. While antimicrobials and non-steroidal anti-inflammatory drugs are typically associated with drug-induced AIN, few reports have been made on the involvement of other analgesics. We report our experience in managing a 17-year-old female with AIN and subsequent renal injury following an acetaminophen overdose in conjunction with acute alcohol intoxication. It is well established that acetaminophen metabolism, particularly at high doses, produces reactive metabolites that may induce renal and hepatic toxicity. It is also plausible however, that such reactive species could instead alter renal peptide immunogenicity, thereby inducing AIN. In the following report, we review a possible mechanism for the acetaminophen-induced AIN observed in our patient and also discuss the potential involvement of acute alcohol ingestion in disease onset. The objective of our report is to increase awareness of healthcare professionals to the potential involvement of these commonly used agents in AIN pathogenesis.

    2006-11-01

    Full Text Available Abstract Background Hornet stings are generally associated with local and occasionally anaphylactic reactions. Rarely systemic complications like acute renal failure can occur following multiple stings. Renal failure is usually due to development of acute tubular necrosis as a result of intravascular haemolysis, rhabdomyolysis or shock. Rarely it can be following development of acute tubulo-interstitial nephritis. Case presentation We describe a young male, who was stung on face, head, shoulders and upper limbs by multiple hornets (Vespa orientalis. He developed acute renal failure as a result of acute tubulo-interstitial nephritis and responded to steroids. Conclusion Rare causes of acute renal failure like tubulo-interstitial nephritis should be considered in a patient with persistent oliguria and azotemia following multiple hornet stings. Renal biopsy should be undertaken early, as institution of steroid therapy may help in recovery of renal function

    The clinical case report of a 14-year-old diabetic teenager with undifferentiated juvenile arthritis and 2-years history of skin-colored maculae and plaques is presented. Biopsy examination of a skin specimen showed findings of early interstitial granulomatous dermatitis. The patient was treated with hydroxicloroquine with partial response. Interstitial granulomatous dermatitis with plaques and arthritis is an idiopathic rare disease that usually affects young women. It is usually related to rheumatoid arthritis or another autoimmune disease. It represents a disorder that involves degeneration of collagen by immune complex-mediated formation and deposition on the endothelial surface. Prognosis is variable with remissions and exacerbations or spontaneous and complete remission of skin lesions. diagnosis.

    Full Text Available This study evaluated histological lesions in kidney samples from pigs with nephritis in two slaughterhouses in the State of Mato Grosso, Brazil. Four hundred samples were subjected to histology, anti-porcine circovirus type 2 (PCV2 immunohistochemistry (IHC, anti-Leptospira sp. immunofluorescence (IF, and polymerase chain reaction (PCR for PCV2, porcine parvovirus (PPV, and Torque teno virus type 1 and 2 (TTV1, TTV2 detection. Histological lesions were found in 81% of the samples, and mononuclear interstitial nephritis was the most frequent lesion (77.50%. A follicular pattern was observed in 40.97% of the interstitial nephritis lesions. PCV2, PPV, TTV1, and TTV2 were identified in the kidneys by PCR in 27.25%, 28.50%, 94%, and 87.5% of the samples, respectively. Leptospira sp. was not detected through IF. Infection by PCV2 (PCR and the presence of histological lesions (P=0.008 and giant cells (P=0.0016 were significantly associated. An association was observed between the TTV2-TTV1 co-infection (P<0.0001 and the risk for pathogenesis. These findings indicated that PCV2, PPV, TTV1, and TTV2 were widely distributed among pigs in the local farms and that the presence of these agents should be considered in the differential diagnosis of kidneys with interstitial nephritis in pigs.

    Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disease of unknown etiology that most frequently involves the skin and the musculoskeletal system. In addition to the more common cutaneous manifestations, interstitial granulomatous dermatitis (IGD) may rarely occur in association with SLE or even be the first sign of the disease. We describe a 40-year-old man with SLE-associated IGD, and review all cases of SLE-associated IGD in the literature. © The Author(s) 2015.

    Acute oliguric renal failure (ARF) developed in a patient 2 days after she was started on intermittent anti-Brucella therapy including rifampicin. The clinical picture was compatible with acute allergic interstitial nephritis. Renal histology revealed mainly acute tubular necrosis with mild tubulo-intertitial mononuclear cellular infiltrate. Intermittent therapy, as in our patient, has been the major factor in the development of rifampicin induced ARF in cases reviewed in literature. (author)

Spontaneous urinoma is rare and parenchymal pathologic change is rarely mentioned when urinoma is found. We present a case of a 28-year-old woman with bilateral flank pain induced by spontaneous urinoma. The lady received chronic analgesics because of migraine. After intravenous ketorolac injection, bilateral perirenal urinoma developed. Renal biopsy showed acute interstitial nephritis associated with nonsteroid anti-inflammatory drug (NSAID. After discontinuing the medication, urinoma subsided, and the patient was discharged with normal serum creatinine. This was the first case of urinoma induced by NSAID-related interstitial nephritis, and pathophysiology and management of spontaneous urinoma are discussed.

    Common variable immunodeficiency (CVID) is a heterogeneous subset of immunodeficiency disorders. Recurrent bacterial infection is the main feature of CVID, but various non-infectious complications can occur. A 42-year-old woman presented with cough and abnormal chest X-ray shadows. Laboratory tests showed remarkable hypogammaglobulinemia. Computed tomography revealed multiple consolidation and nodules on the bilateral lung fields, systemic lymphadenopathy, and splenomegaly. A surgical lung biopsy specimen provided the final diagnosis of lymphoproliferative disease in CVID, which was grouped under the term granulomatous lymphocytic interstitial lung disease. Interestingly, the lung lesions of this case resolved immediately after the initiation of intravenous immunoglobulin monotherapy.

    Full Text Available We report a patient with unknown primary undifferentiated carcinoma who developed acute renal failure associated with interstitial fibrosis following pemetrexed therapy. Despite drug withdrawal, renal function remained altered and the patient experienced chronic renal insufficiency. Pemetrexed disodium (Alimta™ is a multitargeted antifolate agent approved by the Food and Drug Administration (FDA for patients diagnosed with mesothelioma and non-small cell lung cancer. This drug is almost exclusively cleared by renal excretion [1]. The most common side effects are hematologic dose-limiting toxicities and nonhematologic toxicities including fatigue, diarrhea, nausea, mucositis and rash. Although few cases of renal failure have been published, no study has reported on the renal pathological findings in this setting. We present a case of acute tubular necrosis associated with interstitial fibrosis after pemetrexed therapy.

    Common variable immunodeficiency (CVID) is one of the most common primary immunodeficiencies, which is characterized by reduced serum immunoglobulin levels and B-lymphocyte dysfunction. There are many clinical manifestations of this disease, the most common of which are recurrent respiratory tract infections. Among the most recently recognized autoimmune manifestation of CVID is a disease described as granulomatous-lymphocytic interstitial lung disease (GLILD), where CVID coexists with a small airway lymphoproliferative disorder, mimicking follicular bronchiolitis, or lymphocytic interstitial pneumonitis (LIP) on histology specimens. We herein describe the clinical and radiological features of GLILD in a 55-year-old woman where the diagnosis of CVID was actively pursued and eventually confirmed after her lung biopsy showed characteristic features of GLILD. The patient had dramatic response to treatment with IVIG and corticosteroids for 3 months followed by Mycophenolate mofetil for maintenance therapy. © 2016 John Wiley & Sons Ltd.

    Acute interstitial nephritis (AIN) is a common cause of acute kidney injury and is characterised by a dense interstitial cellular infiltrate, which has not been well defined. Previous studies have demonstrated a correlation between Epstein-Barr virus (EBV) infection and AIN. The purpose of our study was to define the nature of the interstitial immune infiltrate and to investigate the possibility of renal infection with EBV.

    Acute interstitial nephritis (AIN) secondary to trimethoprim-sulfamethoxazole (TMP-SMX) is well documented as a cause of acute renal failure in native kidneys. TMP-SMX is the standard prophylactic agent against pneumocystis carinii (PCP) used in the early post-transplant period, however, it has to date only been indirectly associated with AIN in renal allografts. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: We describe eleven renal transplant patients with acute allograft dysfunction in whom a transplant biopsy demonstrated primary histopathologic features of allergic AIN, all of whom were receiving TMP-SMX in addition to other medications known to cause AIN.

    One kidney was taken from each of 100 pigs at slaughter; 50 had gross lesions of multifocal interstitial nephritis and 50 had no gross lesions. Forty-nine of the affected kidneys had lesions that were characterised by the presence of either a few randomly distributed or numerous widely disseminated pale foci, 1 to 3 mm in diameter, on the cortical surface (white-dotted kidneys). Microscopically, these focal inflammatory lesions often had a distinct lymphofollicular pattern (follicular nephritis). Lesions of chronic vasculitis were observed in 21 of the affected kidneys. Histologically, the control kidneys had only small and sparse inflammatory foci. Standard bacterial cultures of kidneys of both groups were not significant, and cultures for the isolation of leptospires were all negative. Virological examination of the kidney homogenates by PCR did not reveal any porcine reproductive and respiratory syndrome virus and only a few cases were positive for the porcine circovirus type 1. However, porcine parvovirus (PPV) and porcine circovirus type 2 (PCV-2) were detected in many kidneys of both groups but in a significantly higher proportion of the kidneys with interstitial nephritis. There was a significant association between the lesions and the presence of PPV and PCV-2 with odds ratios of 7.5 (P<0.0001) and 3.4 (P=0.0074), respectively, and the odds ratio increased to 22.7 (P<0.0001) when both viruses were identified in the same kidney. However, a subsample of kidneys taken from both groups were negative by immunohistochemistry for the presence of PPV and PCV-2 antigens.

    Full Text Available We describe a 19-year-old male who developed diclofenac-induced acute inters-titial nephritis (AIN. Diffuse mononuclear cell infiltration was confirmed by renal biopsy and a Gallium (Ga-67 scintigraphy revealed diffuse uptake of the isotope in both kidneys. His renal function had gradually and promptly recovered after initiation of low-dose prednisolone (0.5 mg/kg/day. There are no established criteria for the administration of corticosteroids in the treatment of drug-induced AIN. Moreover, no clear recommendations regarding the optimal dose and duration of steroid administration in the treatment for drug-induced AIN has been established. In addition, we discuss the clinical benefit of steroid treatment and the diagnostic impact of Ga scanning on the management of drug-induced AIN.

    Full Text Available Sunitinib, a multitargeted tyrosine Kkinase inhibitor (TKI, is currently the standard of care for patients with metastatic renal cell carcinoma. Renal adverse events associated with sunitinib include proteinuria, renal insufficiency secondary to focal segmental glomerulosclerosis (FSGS, and thrombotic microangiopathy. We describe the second reported instance of biopsy-proven sunitinib-induced acute interstitial nephritis (AIN, in a challenging case complicated by thrombocytopenia. The case illustrates the importance of early diagnosis and intervention in ensuring long-term recovery from renal complications. Four other cases of AIN reported along with inhibition of the vascular endothelial growth factor (VEGF by either TKI (sunitinib and sorafenib or antibodies (bevacizumab suggest a possible class effect. Given our experience, we recommend monitoring renal function with VEGF inhibition, and in the case of renal failure in the setting of an unclear diagnosis, we recommend prompt biopsy.

    Granulomatous lymphocytic interstitial lung disease, or GLILD, is an uncommon condition associated with common variable immunodeficiency (CVID). We present an interesting case of an 18-year-old woman with Kabuki syndrome and CVID who was seen in our clinic for an abnormal chest CT scan. She was subsequently diagnosed with GLILD. There are no established guidelines for the treatment of GLILD in CVID. Immune globulin replacement therapy is the main treatment for CVID and higher doses of intravenous immunoglobulin (IVIG) may prevent the progression of chronic lung disease. Patients with CVID and GLILD are at increased risk for malignancy and their prognosis is worse compared to patients with CVID without GLILD.

    We present a 30-year-old combat veteran with an unclear exposure history, with multiple deployments who was later diagnosed with acute renal failure as a result of light-chain deposition disease. Despite a drastic decline in kappa light chains following chemotherapy; his renal function worsened, and he progressed to end-stage renal disease, requiring hemodialysis. Light-chain-mediated acute tubular interstitial nephritis is an uncommon type of monoclonal gammopathy of renal significance presenting with acute renal failure without significant glomerular disease. Our case illustrates that light-chain-mediated acute tubular interstitial nephritis may present clinically like acute interstitial nephritis and that renal biopsy is critical for diagnosis. We also explore possible links between various environmental and occupational exposures that could have precipitated his disease process at such a young age.

    Full Text Available A 54-year-old female presented with recurrent, widespread, erythematous, painful plaques, over a 3-month period. Skin biopsy was compatible with interstitial granulomatous dermatitis. Additional investigation revealed hypothyroidism and positive anti-thyroid antibodies. Normalization of thyroid function and high-potency topical corticosteroids provided only transitory improvement of the dermatosis. Interstitial granulomatous dermatitis is a histologic inflammatory reaction, with variable cutaneous expression. It has been reported in association with several drugs, lymphoproliferative diseases and autoimmune disorders, such as rheumatoid arthritis, systemic lupus erythematosus and vasculitis, but association with autoimmune thyroiditis is rare. Optimal therapy for this condition is yet to be established, but topical corticosteroids have been a mainstay of treatment. In most cases, this disease is characterized by flares and remissions.Uma doente de 54 anos foi avaliada por placas eritematosas, dolorosas, disseminadas, recorrentes, com 3 meses de evolução. A biopsia cutânea foi compatível com dermatite intersticial granulomatosa. Os restantes exames laboratoriais revelaram hipotiroidismo e anticorpos anti-tiroideus positivos. Apesar da normalização da função tiroideia e de tratamento com corticóide tópico de alta potência, a dermatose melhorou apenas parcialmente. Dermatite intersticial inflamatória é um diagnóstico histopatológico, com expressão clínica variável. Tem sido associada a vários fármacos, doenças linfoproliferativas e autoimunes, nomeadamente artrite reumatóide, lupus eritematoso sistémico e vasculites, mas a associação com tireoidite autoimune é rara. Até ao momento, não foi definido nenhum tratamento específico, mas os corticóides tópicos são dos fármacos mais utilizados. A doença caracteriza-se por períodos de agravamento e remissão.

    Immune-checkpoint inhibitors are emerging as revolutionary drugs for certain malignancies. However, blocking the co-inhibitory signals may lead to immune-related adverse events, mainly in the spectrum of autoimmune diseases including colitis, endocrinopathies and nephritis. Here, we report a case of a 75-year-old man with metastatic malignant melanoma treated with a combination of nivolumab (anti-PD1-antibody) and ipilimumab (anti-CTLA-4 antibody) who developed systemic rash along with severe acute tubulointerstitial nephritis after two doses of combination therapy. Kidney biopsy and peripheral blood immune profile revealed highly proliferative and cytotoxic T cell features. Herein, we discuss the pathophysiology and management of immune checkpoint blockade-related adverse events.

    Acute lymphoid leukemia is the most frequently occurring malignancy in childhood, but acute tubulointerstitial nephritis with associated acute renal failure as the leading manifestation of leukemia is extremely rare. Only a few pediatric cases have been described in the literature. We present a surprising case in which physical examination and initial investigation were not typical for leukemia. Ultrasound showed only modest kidney enlargement while laboratory results indicated acute renal failure. Renal biopsy indicated tubulointerstitial nephritis, and subsequent steroid treatment led to sudden clinical improvement. One month later, however, the patient returned with typical clinical features of leukemia. Re-evaluation of the original kidney biopsy block indicated T-cell acute lymphoid leukemia. The present case highlights the importance of renal biopsy. © 2016 Japan Pediatric Society.

    Acute interstitial nephritis (AIN) is a form of acute kidney injury (AKI) characterized by a rapid deterioration of renal function, inflammatory infiltration of interstitial tissues, and renal edema. Drug-induced AIN is the most common etiology of AIN, but AIN can also have infectious, autoimmune, or idiopathic causes. β-Lactam antibacterials, nonsteroidal antiinflammatory drugs, and proton pump inhibitors are recognized as leading causes of AIN; however, many other drugs have been identified as causes. We describe the case of a 59-year-old white male who developed AIN that required hemodialysis following azithromycin treatment. He presented to the hospital with complaints of nausea, vomiting, malaise, and fever over the past 3 days, along with no urine output in the preceding 24 hours. Two weeks earlier, he had completed a 5-day course of azithromycin 500 mg on day 1 followed by 250 mg/day on days 2-5 (total dose 1.5 g) for an upper respiratory tract infection. On admission, the patient's serum creatinine (S(cr)) concentration was 7.4 mg/dl (baseline = 1.3 mg/dl). He reported a similar episode of kidney failure 2 years earlier after taking azithromycin; however, at that time it was believed the AKI was likely due to benazepril use in the setting of acute infection, and a kidney biopsy was not performed. His S(cr) concentration peaked at 11.4 mg/dl, and three sessions of hemodialysis were required. A kidney biopsy was performed that revealed AIN. Low-dose prednisone 0.3 mg/kg (30 mg)/day, tapered over the next 3 months, was administered, and his renal function improved to near baseline prior to discharge; 6 months later, his Scr concentration was 1.4 mg/dl. Despite lower than recommended dosing, this patient responded well to prednisone and did not experience long-term sequelae from renal injury. Use of the Naranjo Adverse Drug Reaction Probability Scale indicated a definite relationship (score of 10) between azithromycin exposure and the manifestation of AIN. To

    Kidney injury molecule-1 (KIM-1) was identified the most highly upregulated protein in chronic kidney diseases and prolonged KIM-1 expression may be maladaptive. The present study was aimed to investigate urinary, renal and plasma KIM-1 levels and to analyze association between KIM-1 levels with clinical and pathological indexes in adult Henoch-Schönlein purpura (HSP) patients. Twenty healthy individuals, 20 HSP patients without nephritis and 35 HSP patients with nephritis were recruited. Urinary and plasma KIM-1 levels were determined by ELISA and Luminex, respectively. Renal KIM-1 expression was evaluated by immunohistochemistry. HSP patients with nephritis were characterized as elevated levels of urinary, renal and plasma KIM-1. Those with more severe tubular injury of renal biopsy tissues presented significantly higher urinary and renal KIM-1 levels compared to control and patients without nephritis. Urinary and renal levels of KIM-1 were positively correlated with blood urea nitrogen and proteinuria, while they were negatively correlated with eGFR at both baseline and after two years follow-up. Moreover, plasma KIM-1 levels were associated with blood urea nitrogen and proteinuria as well. Further univariate correlation analysis indicated urinary and renal KIM-1 levels were positively correlated with interstitial inflammation index and tubulointerstitial chronicity index. Only urinary KIM-1 levels were associated with interstitial inflammation index, tubulointerstitial chronicity index and extracapillary glomerular activity index, after logistic regression analysis. The area under the curve (AUC) for urinary KIM-1/Cr predicting progression of renal damage was significantly greater than the AUC for proteinuria. This finding suggests that measurement of urinary and renal KIM-1 level may be helpful to evaluate severity of renal pathological damage and prognosis in adult HSP patients with nephritis.

    2011-12-01

    Full Text Available Elevated transaminases, hemolysis, and thrombocytopenia in pregnancy are most often caused by a preeclampsia variant—HELLP syndrome (hemolysis, elevated liver enzymes, low platelets. In atypical cases, it is important to consider other causes, such as herpes simplex virus (HSV hepatitis. Acute interstitial nephritis (AIN-induced proteinuria can make distinguishing HELLP from its mimics more difficult. A 43-year-old G4P3 gestational carrier at 28 weeks had abnormal laboratory findings consistent with HELLP, including proteinuria. However, she was normotensive and febrile, prompting an investigation into other possible causes of her signs and symptoms. She ultimately was diagnosed with disseminated HSV infection, started on definitive therapy, and allowed to continue her pregnancy to term. The proteinuria was attributed to AIN. AIN can cause proteinuria in the critically ill pregnant patient. When mimics of HELLP syndrome, such as disseminated HSV infection, are the cause of critical illness, the presence of AIN-induced proteinuria may falsely implicate a hypertensive disorder of pregnancy, resulting in iatrogenic premature delivery of the fetus and failure to initiate definitive potential lifesaving treatment.

    Run Rat® is a rodenticide widely used against small mammals. It comprises of a minimum of 32% zinc phosphide which is highly toxic in acute exposures to humans. It may be consumed accidentally or intentionally. It enters the body via skin, respiratory and gastrointestinal tracts. Zinc phosphide is hydrolyzed by the gastric acid and is transformed into phosphine gas. Phosphine is a respiratory toxin that inhibits cytochrome C oxidase system resulting in renal failure and liver failure. A 35 year old Sri Lankan female presented following ingestion of 2.5 g of Run Rat®, which is a branded preparation of zinc phosphide, resulting in 61 mg/kg poison load. She developed severe acute kidney injury with acute tubular necrosis, subnephrotic ranged proteinuria and tubulointerstitial nephritis for which she underwent haemodialysis three times along with other measures of resuscitation. She also developed elevated liver enzymes with hyperblirubinaemia, hypoalbuminaemia, acute pancreatitis and mild myocarditis. She improved with supportive therapy over a period of 3 weeks. Run Rat® is a commonly used rodenticide and the toxic effects are mediated through conversion of phosphide to phosphine gas. The majority of the deaths had occurred in the first 12 to 24 h and the main causes identified are refractory hypotension and arrhythmias. The late deaths (beyond 24 h) had been commonly due to adult respiratory distress syndrome, liver and renal failure. The outcome is poorer with delayed presentation, development of coagulopathy, hyperglycaemia and multiorgan failure with elevated liver enzymes. In our patient, Zinc phosphide poisoning caused severe acute kidney injury, abnormal liver profile, pancreatitis and possible myocarditis. The patient improved with repeated haemodialysis. The renal biopsy revealed acute tubulointerstitial nephritis with acute tubular necrosis. In tropical countries, the rural population engaged in agriculture has easier access to the compound, as it

    Full Text Available Paroxysmal nocturnal hemoglobinuria is a rare disease of the red blood cell membrane that renders it lyzable by the complement system, leading to chronic intravascular hemolysis. Renal hemosiderosis is a well-known complication of intravascular hemolytic anemia and can lead to acute kidney injury and renal failure. The use of herbal medicine is common worldwide. The nephrotoxicity of herbal remedies can take several forms, which include acute kidney injury and acute and chronic interstitial nephritis. In addition, the use of herbal remedies can result in bone marrow toxicity and suppression. C1q nephropathy is an uncommon form of glomerular disease characterized by dominant or co-dominant glomerular immunofluorescence positivity for C1q in the absence of clinical and serological evidence of systemic lupus erythematosus, and has various clinical presentations and outcome. Here, we report a patient of undiagnosed paroxysmal nocturnal hemoglobinuria who consumed herbal medicine of unknown constituents and clinically presented with anemia and acute kidney injury. The pathological findings of bone marrow and renal biopsies that include bone marrow intoxication, severe renal hemosiderosis and acute interstitial nephritis and kidney injury, as well as co-dominant glomerular deposition of C1q, are discussed. In addition, we discuss and hypothesize the possible pathogenesis of glomerular C1q deposition in the setting of paroxysmal nocturnal hemoglobulinuria.

  2. Pivotal role of Toll-like receptors 2 and 4, its adaptor molecule MyD88, and inflammasome complex in experimental tubule-interstitial nephritis.

    Directory of Open Access Journals (Sweden)

    Matheus Correa-Costa

    Full Text Available Tubule-interstitial nephritis (TIN results in decreased renal function and interstitial inflammation, which ultimately leads to fibrosis. Excessive adenine intake can cause TIN because xanthine dehydrogenase (XDH can convert this purine into an insoluble compound, which precipitates in the tubuli. Innate immune sensors, such as Toll-like receptors (TLR and inflammasome complex, play a crucial role in the initiation of inflammation. The aim of this study was to evaluate the roles of TLR-2 and -4, Myd88 and inflammasome complex in an experimental model of TIN. Here, we show that wild-type (WT mice fed adenine-enriched food exhibited significant renal dysfunction and enhanced cellular infiltration accompanied by collagen deposition. They also presented higher gene and protein expression of pro-inflammatory cytokines. In contrast, TLR-2, -4, MyD88, ASC and Caspase-1 KO mice showed renoprotection associated with expression of inflammatory molecules at levels comparable to controls. Furthermore, treatment of WT animals with allopurinol, an XDH inhibitor, led to reduced levels of uric acid, oxidative stress, collagen deposition and a downregulation of the NF-kB signaling pathway. We concluded that MyD88 signaling and inflammasome participate in the development of TIN. Furthermore, inhibition of XDH seems to be a promising way to therapeutically target the developing inflammatory process.

    Interstitial lung diseases comprise a heterogeneous group of about 200 entities. In the classification of these diseases, diffuse parenchymal lung diseases with known cause, granulomatous diseases, and other specific interstitial lung diseases are separated from the important group of idiopathic interstitial pneumonias, which are classified according to the 2002 ATS/ERS consensus classification. Concerning the histological pattern, this classification differentiates between "usual interstitial pneumonia" (UIP), "nonspecific interstitial pneumonia" (NSIP), "organising pneumonia" (COP), "diffuse alveolar damage" (DAD), "respiratory bronchiolitis" (RB), "desquamative interstitial pneumonia" (DIP), "lymphocytic interstitial pneumonia" (LIP) and "unclassifiable interstitial pneumonias". A key message of this classification is that the pathologist will give the diagnosis of a histological pattern, whereas the final clinicopathologic diagnosis can be made only by the clinical pulmonologist after careful correlation with the clinical and radiologic features, which is essential in the diagnosis of interstitial lung diseases.

    Full Text Available Adenoviruses (AdV are emerging pathogens with a prevalence of 11% viruria and 6.5% viremia in kidney transplant recipients. Although AdV infection is common, interstitial nephritis (ADVIN is rare with only 13 biopsy proven cases reported in the literature. We report a case of severe ADVIN with characteristic histological features that includes severe necrotizing granulomatous lesion with widespread tubular basement membrane rupture and hyperchromatic smudgy intranuclear inclusions in the tubular epithelial cells. The patient was asymptomatic at presentation, and the high AdV viral load (quantitative PCR>2,000,000 copies/mL in the urine and 646,642 copies/mL in the serum confirmed the diagnosis. The patient showed excellent response to a combination of immunosuppression reduction, intravenous cidofovir, and immunoglobulin therapy resulting in complete resolution of infection and recovery of allograft function. Awareness of characteristic biopsy findings may help to clinch the diagnosis early which is essential since the disseminated infection is associated with high mortality of 18% in kidney transplant recipients. Cidofovir is considered the agent of choice for AdV infection in immunocompromised despite lack of randomized trials, and the addition of intravenous immunoglobulin may aid in resolution of infection while help prevention of rejection.

    A proportion of people living with common variable immunodeficiency disorders develop granulomatous-lymphocytic interstitial lung disease (GLILD). We aimed to develop a consensus statement on the definition, diagnosis, and management of GLILD. All UK specialist centers were contacted and relevant physicians were invited to take part in a 3-round online Delphi process. Responses were graded as Strongly Agree, Tend to Agree, Neither Agree nor Disagree, Tend to Disagree, and Strongly Disagree, scored +1, +0.5, 0, -0.5, and -1, respectively. Agreement was defined as greater than or equal to 80% consensus. Scores are reported as mean ± SD. There was 100% agreement (score, 0.92 ± 0.19) for the following definition: "GLILD is a distinct clinico-radio-pathological ILD occurring in patients with [common variable immunodeficiency disorders], associated with a lymphocytic infiltrate and/or granuloma in the lung, and in whom other conditions have been considered and where possible excluded." There was consensus that the workup of suspected GLILD requires chest computed tomography (CT) (0.98 ± 0.01), lung function tests (eg, gas transfer, 0.94 ± 0.17), bronchoscopy to exclude infection (0.63 ± 0.50), and lung biopsy (0.58 ± 0.40). There was no consensus on whether expectant management following optimization of immunoglobulin therapy was acceptable: 67% agreed, 25% disagreed, score 0.38 ± 0.59; 90% agreed that when treatment was required, first-line treatment should be with corticosteroids alone (score, 0.55 ± 0.51).

    Systemic lupus erythematosus (SLE) is known to present with a wide variety of clinical manifestations. Lymphadenopathy is frequently observed in children with SLE and may occasionally be the presenting feature. SLE presenting with granulomatous changes in lymph node biopsy is rare. These features may also cause diagnostic confusion with other causes of granulomatous lymphadenopathy. We report 12 year-old female who presented with generalized lymphadenopathy associated with intermittent fever as well as weight loss for three years. She also had developed anasarca two years prior to presentation. On presentation, she had growth failure and delayed puberty. Lymph node biopsy revealed granulomatous features. She developed a malar rash, arthritis and positive ANA antibodies over the course of next two months and showed WHO class II lupus nephritis on renal biopsy, which confirmed the final diagnosis of SLE. She was started on oral prednisolone and hydroxychloroquine with which her clinical condition improved, and she is currently much better under regular follow up. Generalized lymphadenopathy may be the presenting feature of SLE and it may preceed the other symptoms of SLE by many years as illustrated by this patient. Granulomatous changes may rarely be seen in lupus lymphadenitis. Although uncommon, in children who present with generalized lymphadenopathy along with prolonged fever and constitutional symptoms, non-infectious causes like SLE should also be considered as a diagnostic possibility.

    Drug-related acute tubulointerstitial nephritis is one of the most common causes of childhood acute renal failures which originate from kidneys. Sixteen-year old male patient with the history of isotretinoin use for the last 3 months was admitted with acute renal failure. Renal function parameters were measured as follows: blood urea nitrogen 21 mg/dL, serum creatinine 1.68 mg/dL, cystatin C 1.15 mg/L, and estimated glomerular filtration rate based on cystatin C 56.5 mL/min/1.73 m2. The patient whom pathological signs of renal biopsy sections revealed interstitial mononuclear cell and eosinophilic infiltration was diagnosed with acute tubulointerstitial nephritis. Isotretinoin is a vitamin A-derived agent which is commonly used in the treatment of acne and may cause drug-related acute tubulointerstitial nephritis. What is Known: •Drug-related acute tubulointerstitial nephritis (ATIN) is one of the most common causes of childhood acute renal failures. What is New: •Isotretinoin may cause drug-related acute tubulointerstitial nephritis.

    Lupus nephritis is a major cause of morbidity and mortality in patients with systemic lupus erythematosus. The general consensus is that 60% of lupus patients will develop clinically relevant nephritis at some time in the course of their illness. Prompt recognition and treatment of renal disease is important, as early response to therapy is correlated with better outcome. The present review summarizes our current understanding of the pathogenic mechanisms underlying lupus nephritis and how the disease is currently diagnosed and treated. PMID:22078716

    Full Text Available Background: Despite several years of intensive investigation, relatively few studies have been made of children with lupus nephritis. The prognosis of children with lupus nephritis is poor for those with diffuse proliferative glomerulonephritis and active interstitial inflammation. As newer treatment modalities become available for patients with severe lupus nephritis, it become increasingly important to identify patients at risk for renal failure. The aim of this study was to evaluate the clinical course, histopathology, serologic features and prognostic significance of some parameters, to identify the risk factors for renal failure and mortality in children with lupus nephritis. Materials and Methods: Retrospectively 30 children under 16 years of age with lupus nephritis from 1989 to 1999 were studied. All patients received renal biopsy and follow-up biopsies were performed in 3 children. Lupus nephritis was classified by the World Health Organization (WHO criteria. The clinical and serologic parameters at the time of renal biopsy were recorded. Results: All children underwent renal biopsy within 1 year of disease onset. There were 1 (3.3% patients with class II, 5 (16.7% with class III, 21 (%70 with class IV, and 3 (%10 with class V nephritis based on initial biopsy according to the WHO classification. The mean follow-up time was 60 months. Follow-up biopsies were histologically stationary in 2 patients and progressive in one. The overall renal and patient 5- year survival rates were 46.66% (14/30 and 93.33 %( 2/30 respectively. They were 47.61% (10/21 and 95.21 %( 20/21, respectively, of patients with class IV proliferative glomerulonephritis. Children with renal pathology (class V in the WHO classification system at initial biopsy, were at high risk for renal failure 66.66% (2/3 or morality %33.33 (1/3 despite aggressive treatment. The results revealed that those with persistent hypertension, anemia, and decreased creatinine clearance rate

    Full Text Available A 2½-year-old child presented with multiple discrete granulomatous lesions on the face and flexural regions since the age of 2 months along with lymphadenopathy. The patient also had recurrent bouts of pyodermas and respiratory tract infections. Biopsy of the lesion showed necrosis of tissue with suppuration and histiocytes but no evidence of tuberculosis, fungal infections or atypical mycobacteria. Lymph node biopsy also showed necrosis with suppuration but no infective organism. Nitroblue tetrazolium test was negative indicating that the neutrophils failed to oxidize the dye. We are reporting here a rare case of chronic granulomatous disease.

    Granulomas as signs of specific inflammation of the lungs are found in various diseases with pulmonary manifestations and represent an important imaging finding. The standard imaging modality for the work-up of granulomatous diseases of the lungs is most often thin-slice computed tomography (CT). There are a few instances, e. g. tuberculosis, sarcoidosis and silicosis, where a chest radiograph still plays an important role. Further radiological modalities are usually not needed in the routine work-up of granulomatous diseases of the chest. In special cases magnetic resonance imaging (MRI) and positron emission tomography (PET)-CT scans play an important role, e. g. detecting cardiac sarcoidosis by cardiac MRI or choline C-11 PET-CT in diagnosing lung carcinoma in scar tissue after tuberculosis. The accuracy of thin-slice CT is very high for granulomatous diseases. In cases of chronic disease and fibrotic interstitial lung disease it is important to perform thin-slice CT in order to diagnose a specific disease pattern. Thin-slice CT is also highly sensitive in detecting disease complications and comorbidities, such as malignancies. Given these indications thin-slice CT is generally accepted in the routine daily practice. A thin-slice CT and an interdisciplinary discussion are recommended in many cases with a suspected diagnosis of pulmonary granulomatous disease due to clinical or radiographic findings. (orig.) [de

    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions.

    Infiltration by IgG-positive plasma cells is a common finding in tubulointerstitial nephritis. Indeed, it has been thought that CD138-positive mature plasma cells secrete mainly IgG, and the occurrence of tubulointerstitial nephritis with CD138-positive plasma cells secreting IgM has rarely been reported. Routine immunofluorescence of fresh frozen sections is considered the gold standard for detection of immune deposits. However, the immunoenzyme method with formalin-fixed, paraffin-embedded sections is superior for detecting IgM- or IgG-positive cells within the renal interstitium, thus histologic variants may often go undetected. We recently discovered a case of tubulointerstitial nephritis showing IgM-positive plasma cell accumulation within the interstitium. To further explore the morphologic and clinical features of such cases, we performed a nationwide search for patients with biopsy-proven tubulointerstitial nephritis and high serum IgM levels. We identified 13 patients with tubulointerstitial nephritis and IgM-positive plasma cell infiltration confirmed with the immunoenzyme method. The clinical findings for these patients included a high prevalence of distal renal tubular acidosis (100%), Fanconi syndrome (92%), and anti-mitochondrial antibodies (82%). The pathologic findings were interstitial nephritis with diffusely distributed CD3-positive T lymphocytes and colocalized IgM-positive plasma cells, as well as tubulitis with CD3-positive T lymphocytes in the proximal tubules and collecting ducts. Additionally, levels of H + -ATPase, H + , K + -ATPase, and the HCO 3 - -Cl - anion exchanger were markedly decreased in the collecting ducts. We propose to designate this group of cases, which have a common histologic and clinical form, as IgM-positive plasma cell-tubulointerstitial nephritis.

    Full Text Available Allergic granulomatous angiitis (AGA - Churg-Strauss syndrome, is a rare autoimmune disease characterized by three distinct clinical phases prodromal, eosinophilic, and vasculitic, and most of respiratory symptoms and signs begin in the first two phases of the disease. Two female patients of different age, who fulfilled the diagnostic criteria for AGA, and were in different phases and with the different duration of the disease are presented. The first patient (24 years of age was admitted to the hospital due to aggravation of asthma, heart failure, and polyneuropathy. The second one (45 years of age was also hospitalized due to the worsening of asthma polyneuropathy, and fever. Both were treated continuously with glucocorticoids. The older patient also received a total of six pulse doses of cyclophosphamide. Satisfactory response to such a treatment was achieved in both cases.

    Nephropathy associated with IgG4-related disease is characterized by tubulointerstitial nephritis. To better identify its pathology, the present study analyzed clinicopathologic features of IgG4-related tubulointerstitial nephritis cases from across Japan. Sixteen cases were identified as IgG4-related nephropathy using the criterion of high serum IgG4 levels (>135 mg/dL) with abnormal kidney computed tomography or elevated serum creatinine levels. Male predominance (75%) and advanced age (average, 62.0 years) were noted. Eight cases displayed no autoimmune pancreatitis. Renal computed tomography abnormalities were found in 12 of 13 cases examined. Renal dysfunction was found in 15 of 16 cases at biopsy. Distinctive features of tubulointerstitial lesions included (1) well-demarcated borders between involved and uninvolved areas; (2) involvement of the cortex and medulla, often extending beyond the renal capsule and with occasional extension to retroperitoneal fibrosis; (3) interstitial inflammatory cells comprising predominantly plasma cells and lymphocytes, with a high prevalence of IgG4-positive cells often admixed with fibrosis; (4) peculiar features of interstitial fibrosis resembling a "bird's-eye" pattern comprising fibrosis among inter-plasma cell spaces; and (5) deposits visible by light and immunofluorescent microscopy in the tubular basement membrane, Bowman capsule, and interstitium that are restricted to the involved portion, sparing normal parts. Ultrastructural analysis revealed the presence of myofibroblasts with intracellular/pericellular collagen accompanied by plasma cell accumulation from an early stage. Histology could not discriminate between IgG4-related tubulointerstitial nephritis with and without autoimmune pancreatitis. In conclusion, the distinctive histologic features of IgG4-related tubulointerstitial nephritis can facilitate the differential diagnosis of tubulointerstitial nephritis, even without autoimmune pancreatitis or an abnormal

    The describe the radiologic findings of granulomatous mastitis of the breast. This study included 19 patients (age range: 22 to 56 years; mean 37 years) with 22 lesions that were pathologically confirmed as having granulomatous mastitis. All the patients underwent a breast ultrasonography and 13 patients underwent a mammography. The results of the mammography revealed focal asymmetry (n = 9), multiple ill-defined isodense nodules (n 2), ill-defined nodular density on craniocaudal view (n = 1), and unremarkable finding (n = 1). The sonographic findings included continuous or discontinuous multiple tubular and nodular low echoic lesions (n = 7), ill-defined heterogeneously low echoic lesion (n = 5), irregular-shaped, ill-defined low echoic mass (n = 4), fluid collection with internal floating materials suggesting the presence of an abscess (n = 4), ill-defined heterogeneously low echoic lesion and abscess (n = 1), and multiple ill-defined nodules (n = 1). In the case of granulomatous mastitis, the mammography results indicate a lack of specificity between normal findings and focal asymmetry. The sonographic findings indicate that ill-defined heterogeneously low echoic lesions or irregular shaped, ill-defined low echoic masses are difficult to differentiate from breast cancer. The sonographic findings of abscesses indicate a difficulty in differentiating them from cases of pyogenic mastitis. However, multiple tubular and nodular low echoic lesions, especially with a continuous appearance, should point to granulomatous mastitis, and is helpful in its differential diagnosis and treatment.

    Tubulointerstitial Nephritis with Uveitis (TINU) syndrome is a rarely seen syndrome. The interstitial nephritis may be with the concurrent uveitis and can also develop before or after uveitis. The syndrome can resolve after elimination of the culprit destructive factors, such as drugs, toxins and immune reaction. Synthetic cannabinoids have emerged as drugs of abuse with increasing popularity among young adults. Recent literature has documented reports of acute kidney injury in association with the use of synthetic cannabinoids; however, there is no report of TINU syndrome development secondary to using of synthetic cannabinoids. Herein, we report a 42-year-old male with TINU syndrome associated with smoking synthetic cannabinoid.

A rare type of lupus nephritis, class V, shows histological findings resembling those of membranous nephropathy. While most diffuse proliferative lupus nephritis is associated with other SLE disease activity, class V lupus nephritis can occur without systemic activity. Furthermore, Class V is less responsive to steroid therapy than other forms of lupus nephritis. We treate...

    Full Text Available Gallbladder granulomas are exceedingly rare, reported in association with tuberculosis or sarcoidosis. Here we report a case of gallbladder granulomatous cholecystitis occurring in the context of sarcoidosis. A 70-years old man presented with abdominal pain, nausea and vomiting. The medical history revealed sarcoidosis diagnosed more than 20-years previously. 2-years previously the patient showed renal lithiasis, hypercalcemia and, increased angiotensin converting enzyme. The imaging features suggested thoraco-abdominal sarcoidosis. Prednisone was given at 1.2 mg/kg/day initially, than decreased, being at 2.5 mg/day at present. The ultrasound examination showed gallbladder lithiasis. A cholecystectomy was performed. Microscopy showed subacute and chronic cholecystitis with several epithelioid and giant cell granulomas some of them perineural. In conclusion, we report a case of granulomatous cholecystitis occurring in the course of treated sarcoidosis. The perineural location of granulomas may give further insights into the pathogenesis of gallbladder dysmotility.

    To determine the clinicopathological pattern of lupus nephritis in paediatric nephrology patients. Twenty six patients upto the age 16 years of either gender, with a mean age of 12.4 +- 1.90 years having primary SLE with renal involvement in the form of oedema, hypertension, haematuria and proteinuria were included. Twenty one were females. Percutaneous renal biopsy was performed. Histological lesion was classified according to WHO classification. Patients were treated with immunosuppressive therapy and their clinical course was followed for at least one year. The mean duration of follow up was 1.77 years. Renal involvement was seen in 92.30% within 2 years of the onset of primary disease. Diffuse proliferative glomerulonephritis was the commonest histological lesion (n=14) followed by membranous nephropathy (n=6). The commonest clinical manifestation was oedema (80.76%) followed by hypertension (46.15%). Proteinuria was present in 100% of cases, haematuria in 38.46% and azotemia in 19.33% of patients. Nephrotic range proteinuria was more common in class III and IV, while azotemia was observed only in class IV. The disease was well controlled in 73.07% , relapse was seen in 3.8% of patients, 15.38% died of infections and uremic encephalopathy while 7.69% were lost to follow-up. Diffuse proliferative glomerulonephritis is the commonest histological lesion in our set-up. Renal involvement is mostly seen within first two years of the primary disease which can be controlled satisfactorily with immunosuppressive therapy. (author)

    Immunoglobulin G4 (IgG4)-related tubulointerstitial nephritis is a newly recognized clinicopathologic entity that may occur as an isolated renal lesion or as part of a multisystem disorder. It is characterized by plasma cell-rich interstitial nephritis with abundant IgG4-positive plasma cells and IgG-dominant tubulointerstitial immune deposits. We report the first case of IgG4-related tubulointerstitial nephritis with multifocal plasma cell-rich renal arteritis presenting as acute kidney injury in a 72-year-old man. Seven weeks of prednisone therapy led to nearly complete recovery of kidney function. This case enlarges the morphologic spectrum of this disorder and emphasizes the need to distinguish it from other causes of renal vasculitis. Copyright © 2013 National Kidney Foundation, Inc.

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Systemic lupus erythematosus is characterized by a breakdown of self-tolerance and production of autoantibodies. Kidney involvement (i.e., lupus nephritis is both common and severe and can result in permanent damage within the glomerular, vascular, and tubulo-interstitial compartments of the kidney, leading to acute or chronic renal failure. Accumulating evidence shows that anti-dsDNA antibodies play a critical role in the pathogenesis of lupus nephritis through their binding to cell surface proteins of resident kidney cells, thereby triggering the downstream activation of signaling pathways and the release of mediators of inflammation and fibrosis. This paper describes the mechanisms through which autoantibodies interact with resident renal cells and how this interaction plays a part in disease pathogenesis that ultimately leads to structural and functional alterations in lupus nephritis.

She had elevated BUN and creatinine and urinalysis revealed decreased concentration, proteinuria, hematuria, and pyuria. A kidney biopsy showed non-caseating granulomatous tubulointerstitial nephritis. She suffered from anterior uveitis one month before, which was managed with local ophthalmic steroids. She received two months of oral high dose prednisolone, which was tapered over the next two months, and two months of 2 mg/kg cyclophosphamide. Her renal function recovered during the first two months. Her kidney and ocular symptoms did not recur during one year of follow-up. We suggest short course of cyclophosphamide and prednisolone for treatment of TINU syndrome to decrease the recurrence of kidney and ocular involvement. (author)

    Approximately 10% of patients with common variable immune deficiency have systemic granulomatous disease with associated interstitial lung disease. From a population of patients with CVID attending a large tertiary referral clinic for primary immunodeficiency diseases we selected a cohort who had a restrictive defect or impaired gas transfer on pulmonary function testing and/or histologically proven granulomatous disease. HRCT scans of the thorax were reviewed retrospectively in 18 patients by two radiologists. Thirteen patients had diffuse reticulation, which varied from fine to coarse with features of fibrosis. Nodules were found in eight patients. In seven, these were associated with reticulation and in one they were an isolated finding. Bronchiectasis was found as the only abnormality in three and in addition to diffuse reticulation or nodules in another three patients. Greater appreciation of the spectrum of the radiological abnormalities in CVID patients with interstitial lung disease is important. Deteriorating lung function in patients with granulomatous CVID may be secondary to interstitial lung disease rather than bronchiectasis, and treatment should be tailored accordingly.

  18. The Pathogenesis of Lupus Nephritis

    Science.gov (United States)

    Lech, Maciej

    2013-01-01

    Lupus nephritis is an immune complex GN that develops as a frequent complication of SLE. The pathogenesis of lupus nephritis involves a variety of pathogenic mechanisms. The extrarenal etiology of systemic lupus is based on multiple combinations of genetic variants that compromise those mechanisms normally assuring immune tolerance to nuclear autoantigens. This loss of tolerance becomes clinically detectable by the presence of antinuclear antibodies. In addition, nucleic acids released from netting or apoptotic neutrophils activate innate and adaptive immunity via viral nucleic acid-specific Toll-like receptors. Therefore, many clinical manifestations of systemic lupus resemble those of viral infection. In lupus, endogenous nuclear particles trigger IFN-α signaling just like viral particles during viral infection. As such, dendritic cells, T helper cells, B cells, and plasma cells all contribute to the aberrant polyclonal autoimmunity. The intrarenal etiology of lupus nephritis involves antibody binding to multiple intrarenal autoantigens rather than the deposition of circulating immune complexes. Tertiary lymphoid tissue formation and local antibody production add to intrarenal complement activation as renal immunopathology progresses. Here we provide an update on the pathogenic mechanisms that lead to lupus nephritis and provide the rationale for the latest and novel treatment strategies. PMID:23929771

    Full Text Available Anti-Neutrophil Cytoplasmic Antibodies (ANCA-associated vasculitides (AAV are characterized by small vessel injury and in some cases granulomatous lesions and glomerular inflammation. The pathogenic bases of these clinical phenotypes are incompletely understood, but evidence from patients with AAV and other inflammatory diseases suggest a role for monocyte/macrophages in the perpetuation of tissue injury. Macrophage colony stimulating factor (M-CSF is a promoter of monocyte recruitment and macrophage proliferation, involved in mesangial cell proliferation and experimental nephritis development. Serum concentrations of M-CSF mark and herald the onset of lupus nephritis. Plasma samples from 29 patients with AAV (18 granulomatosis with polyangiitis, GPA, 6 eosinophilic granulomatosis with polyangiitis, EGPA, and 5 microscopic polyangiitis, MPA and from 10 healthy controls were collected together with clinical data. Patients with AAV had higher levels of M-CSF when compared to controls. M-CSF levels correlated positively with the BVAS, serum C-reactive protein and erythrocyte sedimentation rate, while haemoglobin correlated inversely with M-CSF. Patients with active renal disease had significantly higher levels of M-CSF when compared to the other subgroups. M-CSF levels did not differ between ANCA subserotypes and were not associated with the involvement of other organs. In conclusion, M-CSF is higher in patients with AAV and active nephritis and could contribute to the pathogenesis of these diseases. In addition, M-CSF could behave as a useful marker of renal involvement in AAV.

    Granulomatous cheilitis is a rare disease included among the orofacial granulomatoses. It is characterized by a idiopathic chronic inflammation of the labial mucosa (macrochelia), which takes the form of episodic and progressive outbreaks. In 10% of patients, it is associated with Crohn's disease. We report the presentation, evaluation and treatment of a case of granulomatous cheilitis which appearted two years after the onset of Crohn's disease. We conclude that granulomatous cheilitis is rare in children, with few reported cases, although probably underdiagnosed because of lack of awareness. The diagnosis of granulomatous cheilitis is clinical, although the histological evaluation is a determining factor. After making the diagnosis a comprehensive assessment of the patient is recommended, to rule out the other associated syndromes described in the literature.

    Antagonists of tumor necrosis factor-alpha (ATNF) are used for the treatment of multiple diseases such as psoriatic arthritis, Crohn's disease, ankylosing spondylitis and juvenile idiopathic arthritis, usually, when they are refractory to first-line treatment 1 . The use of ATNF has been associated with the induction of autoimmune diseases such as systemic lupus erythematosus-like disease, vasculitis, sarcoidosis-like diseases and, recently, acute granulomatous tubulointerstitial nephritis. We report a case of acute nongranulomatous tubulointerstitial nephritis in an HLA-B27-positive patient with axial spondyloarthritis and Crohn's disease being treated with adalimumab.

    Full Text Available Lupus nephritis, which has various histological patterns and variable clinical outcomes, is one of the most important complications of systemic lupus nephritis (SLE. This pathogenetic mechanism in each histologically different type of lupus nephritis (LN remains unclear. Although SLE is suggested to be a Th2-driven disease, elevation of both Th1 and Th2 cytokines occurs in both humans and mice, suggesting that SLE is a complex disease driven by different lymphocyte subsets with high heterogeneity of clinical manifestations and organ involvement. Recent findings in LN elucidate an essential role for the Th1, IL-17 producing T cells and Th17 cells in the development of diffuse proliferative lupus nephritis (DPLN, and Th2 cytokine in that of membranous lupus nephritis (MLN. These data support the hypothesis that individual Th1/Th2 balance is one of the critical determinants for histopathology of LN.

  9. The Role of Hyaluronan and CD44 in the Pathogenesis of Lupus Nephritis

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Systemic lupus erythematosus (SLE is a prototype autoimmune disease that affects multiorgan systems. Lupus nephritis is one of the most severe manifestations of SLE whereby immune-mediated inflammation can lead to permanent damage within the glomerular, tubulo-interstitial, and vascular compartments of the kidney, resulting in acute or chronic renal failure. The mechanisms that regulate host inflammatory responses and tissue injury are incompletely understood. Accumulating evidence suggests that hyaluronan and its interaction with its cell surface receptor CD44 plays an important role in mediating pathogenic mechanisms in SLE. This paper discusses the putative mechanisms through which hyaluronan and CD44 contribute to the pathogenesis of SLE, with particular emphasis on lupus nephritis.

    The expression of connective tissue growth factor mRNA in human kidneys may serve as an early marker for lupus nephritis progression. Therefore, we speculated that connective tissue growth factor may be involved in the pathogenesis of systemic lupus erythematosus and lupus nephritis. In this study, we set out to investigate the associations between serum connective tissue growth factor levels and clinicopathological features of patients with systemic lupus erythematosus and lupus nephritis. Serum samples from patients with non-renal systemic lupus erythematosus, renal biopsy-proven lupus nephritis and healthy control subjects were detected by enzyme-linked immunosorbent assay for serum connective tissue growth factor levels. The associations between connective tissue growth factor levels and clinicopathological features of the patients were further analysed. The levels of serum connective tissue growth factor in patients with non-renal systemic lupus erythematosus and lupus nephritis were both significantly higher than those in the normal control group (34.14 ± 12.17 ng/ml vs. 22.8 ± 3.0 ng/ml, plupus erythematosus and lupus nephritis group (34.14 ± 12.17 ng/ml vs. 44.1 ± 46.8 ng/ml, p = 0.183). Serum connective tissue growth factor levels were significantly higher in lupus nephritis patients with the following clinical manifestations, including anaemia (51.3 ± 51.4 ng/ml vs. 23.4 ± 9.7 ng/ml, plupus nephritis (63.3 ± 63.4 ng/ml vs. 38.3 ± 37.9 ng/ml, p = 0.035, respectively). Serum connective tissue growth factor levels were negatively associated with estimated glomerular filtration rate (r = -0.46, plupus nephritis (plupus and correlated with chronic renal interstitial injury and doubling of serum creatinine in patients with lupus nephritis. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    2015-02-01

    The term refractory lupus nephritis is generally used to indicate cases that do not respond to traditional treatment. However, the clinical presentation of lupus nephritis is variable and the time to response depends on the typology of the underlying renal syndrome. The criteria and the time for response are different in lupus patients with nephritic flares, in those with nephrotic syndrome, and in those with asymptomatic renal disease. In this paper, we will focus on the clinical characteristics, the consequences, and the possible therapeutic approaches for patients with different forms of refractory lupus nephritis, defined on the basis of renal syndrome at presentation.

    2006-01-01

    We report a 36-year-old woman, presented with cervical lymphadenopathy and low-grade fever. Two fine needle aspiration cytology and one excisional biopsy were performed in the referral hospital, all showed granulomatous lesions without necrosis. A tentative diagnosis of tuberculosis was made, and she started on antituberculous treatment. However, there was no clinical improvement. She presented to our institution one year after the initial diagnosis, and a new biopsy from the cervical lymph node revealed effacement of the whole node by marked non-necrotizing granulomatous reaction. However, there were scattered large cells with few classic Reed-Sternberg cells between the granulomas. Immunohistochemistry reveals strong reaction of CD15 and CD30, and negative staining for CD45RB, CD45RO, and CD20. These findings confirmed the diagnosis of Hodgkin's lymphoma with remarkable granulomatous reaction that almost masked the malignant component. She was treated with chemotherapy, and she showed an excellent response. (author)

    Full Text Available Use of nanomaterials in manufactured consumer products is a rapidly expanding industry and potential toxicities are just beginning to be explored. Combustion-generated multiwall carbon nanotubes (MWCNT or nanoparticles are ubiquitous in non-manufacturing environments and detectable in vapors from diesel fuel, methane, propane, and natural gas. In experimental animal models, carbon nanotubes have been shown to induce granulomas or other inflammatory changes. Evidence suggesting potential involvement of carbon nanomaterials in human granulomatous disease, has been gathered from analyses of dusts generated in the World Trade Center disaster combined with epidemiological data showing a subsequent increase in granulomatous disease of first responders. In this review we will discuss evidence for similarities in the pathophysiology of carbon nanotube-induced pulmonary disease in experimental animals with that of the human granulomatous disease, sarcoidosis.

    Systemic lupus erythematosus (SLE) is a systemic disease of unknown aetiology with variable course and prognosis. Lupus nephritis (LN) is one of the important disease manifestations of SLE with considerable influence on patient outcomes. Immunosuppression therapy has made it possible to control the disease with improved life expectancy and quality of life. In the last few decades, various studies across the globe have clarified the role, dose and duration of immunosuppression currently in use and also provided evidence for new agents such as mycophenolate mofetil, calcineurin inhibitors and rituximab. However, there is still a need to develop new and specific therapy with less adverse effects. In this review, the current evidence of the treatment of LN and its evolution, and new classification criteria for SLE have been discussed. Also, rationale for low-dose intravenous cyclophosphamide as induction agent followed by azathioprine as maintenance agent has been provided with emphasis on individualized and holistic approach.

  17. Granulomatous responses in larval taeniid infections.

    2018-05-01

    Granulomas are responses to persistent nonliving bodies or pathogens, centrally featuring specialized macrophage forms called epithelioid and multinucleated giant cells. The larval stages of the cestode parasites of the Taeniidae family (Taenia, Echinococcus) develop for years in fixed tissue sites in mammals. In consequence, they are targets of granulomatous responses. The information on tissue responses to larval taeniids is fragmented among host and parasite species and scattered over many decades. We attempt to draw an integrated picture of these responses in solid tissues. The intensity of inflammation around live parasites spans a spectrum from minimal to high, parasite vitality correlating with low inflammation. The low end of the inflammatory spectrum features collagen capsules proximal to the parasites and moderate distal infiltration. The middle of the spectrum is dominated by classical granulomatous responses, whereas the high end features massive eosinophil invasions. Across the range of parasite species, much observational evidence suggests that eosinophils are highly effective at killing larval taeniids in solid tissues, before and during chronic granulomatous responses. The evidence available also suggests that these parasites are adapted to inhibit host granulomatous responses, in part through the exacerbation of host regulatory mechanisms including regulatory T cells and TGF-β. © 2018 John Wiley & Sons Ltd.

    Full Text Available Acute interstitial nephritis (AIN is a condition in which acute kidney injury (AKI is characterized by the histological finding of interstitial inflammation. Hyponidd is an ayurvedic drug containing Momordica charantia, Gymnema sylvestre, Swertia chirata, etc., used for the treatment of Type 2 diabetes mellitus (DM and polycystic ovarian disease as an insulin sensitizer. There are no case reports of AIN caused by this drug yet. We report a biopsy-proven case of AKI due to severe AIN associated with the use of hyponidd tablet in a 60-year-old male with DM and hypertension. As these types of various indigenous compounds are used as home remedies in our country, awareness about the possible adverse effects of these agents among physicians is very important in the early diagnosis and management.

    Pyelonephritis is a leading cause of renal failure and is expected to cost as much as three billion dollars in 1984. The diagnosis of urinary tract infection is usually not difficult. However, localization of the infection within the renal parenchyma as opposed to the collecting system is much more difficult. Flank pain, fever, bacteiuria and evidence of parenchymal involvement by intravenous urography may be absent or unrecognized particularly in the infant. Ultrasound and Nuclear Medicine are advocated as better methods to define parenchymal involvement. Such definition is important in the consideration of treatment since parenchymal involvement of the kidney carries a much more ominous potential outcome than infection restricted to within the collecting system. 38 children with a clinical diagnosis of urinary tract infection were studied. 26 of the patients demonstrated abnormal renal parenchymal findings with Gallium-67 Citrate or Tc-99m Glucoheptonate scintigraphy. Intravenous urography was notably ineffective with only 5 of the 20 interpreted as abnormal due to parenchymal disease or decreased function. 11 were entirely normal while only 5 demonstrated scars or hydronephrosis. Only 10 of 17 patients demonstrated intranvesicoureteral reflux on x-ray or nuclear cystography. Ultrasound depicted 6 of 20 patients as having parenchymal abnormalities. Seven were normal. Nonspecific findings such as dilitation of the renal pelvis or renal enlargement was noted in 11 of the 20 patients. Radionuclide Scintigraphy is the most efficacious modality to detect since acute bacterial nephritis.

    Renal involvement in patients with systemic lupus erythematosus in the form of severe lupus nephritis is associated with a significant burden of morbidity and mortality. Conventional laboratory biomarkers in current use have not been very successful in anticipating disease flares, predicting renal histology, or decreasing unwanted outcomes. Since early treatment is associated with improved clinical results, it is thus essential to identify new biomarkers with substantial predictive power to reduce the serious sequelae of this difficult to control lupus manifestation. Indeed, considerable efforts and progress have been made over the last few years in the search for novel biomarkers. Since urinary biomarkers are more easily obtainable with much less risk to the patient than repeat renal biopsies, and these may more accurately discern between renal disease and other organ manifestations than their serum counterparts, there has been tremendous interest in studying new candidate urine biomarkers. Below, we review several promising urinary biomarkers under investigation, including total proteinuria and microalbuminuria, urinary proteomic signatures, and the individual inflammatory mediators interleukin-6, vascular cell adhesion molecule-1, CXCL16, IP-10, and tumor necrosis factor-like weak inducer of apoptosis.

    Full Text Available Kidney disease is one of the most serious manifestations of systemic lupus erythematosus (SLE. Despite the improvement in the medical care of SLE in the past two decades, the prognosis of lupus nephritis remains unsatisfactory. Besides exploring more effective but less toxic treatment modalities that will further improve the remission rate, early detection and treatment of renal activity may spare patients from intensive immunosuppressive therapies and reduce renal damage. Conventional clinical parameters such as creatinine clearance, proteinuria, urine sediments, anti-dsDNA, and complement levels are not sensitive or specific enough for detecting ongoing disease activity in the lupus kidneys and early relapse of nephritis. Thus, novel biomarkers are necessary to enhance the diagnostic accuracy and sensitivity of lupus renal disease, prognostic stratification, monitoring of treatment response, and detection of early renal flares. This paper reviews promising biomarkers that have recently been evaluated in longitudinal studies of lupus nephritis.

    We wanted to describe the characteristic ultrasonography (US) features and clinical findings for making the diagnosis of subacute granulomatous thyroiditis. A total of 31 lesions from 27 patients were confirmed as subacute granulomatous thyroiditis by US-guided fine needle aspiration biopsy. We analyzed the ultrasonographic findings such as the lesion's size, margin and shape, the discrepancy between length and breadth and the vascularity. The clinical findings such as acute neck pain or fever were reviewed. The follow-up clinical and ultrasonographic data were reviewed for 15 patients. The thyroid gland was found to be enlarged in five patients, it was normal size in 20 patients and it was smaller in two patients. All the lesions had focally ill-defined hypoechogenicity. Hypervascularity was not noted in any of the lesions. Painful neck swelling was present in 18 patients. An accompanying fever was documented in nine of the 18 patients. Twelve patients showed disappearance (n = 3) or a decreased size (n = 9) of their lesions on follow-up US. The presence of ill-defined hypoechoic thyroid lesions without a discrete round or oval shape is characteristic for subacute granulomatous thyroiditis, and particularly when this is associated with painful neck swelling and/or fever.

    Granulomatous reactions to tattoo ink are most commonly associated with mercury sulfide, a component of red pigments. Treatment options show limited results. Allopurinol, an inhibitor of xanthine oxidase, has been reported as a successful alternative treatment to granulomatous disorders, such as sarcoidosis and granulomatous reactions to fillers and tattoos. We report a case of granulomatous reaction to red tattoo pigment treated with allopurinol for 6 months. Good clinical improvement could be noticed during this time. Two months after we stopped the treatment, the lesion recurred. Allopurinol emerges as an important drug for the management of granulomatous reactions caused by tattoo pigments. Based on the significant clinical improvement noticed during its use, we recommend new studies to elucidate all the potential benefits of the use of allopurinol for the treatment of granulomatous reactions to tattoo ink. © 2015 Wiley Periodicals, Inc.

    Patients with X-linked agammaglobulinemia (XLA) develop immune-complex induced diseases such as nephropathy only rarely, presumably because their immunoglobulin (Ig) G concentration is low. We encountered a patient with XLA who developed tubulointerstitial nephritis during treatment with intravenous immunoglobulin (IVIG). A 20-year-old man was diagnosed with XLA 3 months after birth and subsequently received periodic γ-globulin replacement therapy. Renal dysfunction developed at 19 years of age in association with high urinary β2-microglobulin (MG) concentrations. A renal biopsy specimen showed dense CD3-positive lymphocytic infiltration in the tubulointerstitium and tubular atrophy, while no IgG4-bearing cell infiltration was found. Fibrosclerosis and crescent formation were evident in some glomeruli. Fluorescent antibody staining demonstrated deposition of IgG and complement component C3 in tubular basement membranes. After pulse steroid therapy was initiated, urinary β2-MG and serum creatinine concentrations improved. Neither drug reactions nor collagen disease were likely causes of tubular interstitial disorder in this patient. Although BK virus was ruled out, IgG in the γ-globulin preparation might have reacted with a pathogen present in the patient to form low-molecular-weight immune complexes that were deposited in the tubular basement membrane.

    Full Text Available Lupus nephritis (LN is a major manifestation of systemic lupus erythematosus (SLE. It remains unclear whether antiphospholipid antibodies (aPL alter the course of LN. We thus investigated the impact of aPL on short-term and long-term renal outcomes in patients with LN. We assessed levels of aPL cross-sectionally in SLE patients diagnosed with (n = 204 or without (n = 294 LN, and prospectively in 64 patients with active biopsy-proven LN (52 proliferative, 12 membranous, before and after induction treatment (short-term outcomes. Long-term renal outcome in the prospective LN cohort was determined by the estimated glomerular filtration rate (eGFR and the Chronic Kidney Disease (CKD stage, after a median follow-up of 11.3 years (range: 3.3-18.8. Cross-sectional analysis revealed no association between LN and IgG/IgM anticardiolipin or anti-β2-glycoprotein I antibodies, or lupus anticoagulant. Both aPL positivity and levels were similar in patients with active LN and non-renal SLE. Following induction treatment for LN, serum IgG/IgM aPL levels decreased in responders (p<0.005 for all, but not in non-responders. Both at active LN and post-treatment, patients with IgG, but not IgM, aPL had higher creatinine levels compared with patients without IgG aPL. Neither aPL positivity nor levels were associated with changes in eGFR from either baseline or post-treatment through long-term follow-up. Moreover, aPL positivity and levels both at baseline and post-treatment were similar in patients with a CKD stage ≥3 versus 1-2 at the last follow-up. In conclusion, neither aPL positivity nor levels were found to be associated with the occurrence of LN in SLE patients. However, IgG aPL positivity in LN patients was associated with a short-term impairment of the renal function while no effect on long-term renal outcome was observed. Furthermore, IgG and IgM aPL levels decreased following induction treatment only in responders, indicating that aPL levels are

    Granulomas as signs of specific inflammation of the lungs are found in various diseases with pulmonary manifestations and represent an important imaging finding. The standard imaging modality for the work-up of granulomatous diseases of the lungs is most often thin-slice computed tomography (CT). There are a few instances, e. g. tuberculosis, sarcoidosis and silicosis, where a chest radiograph still plays an important role. Further radiological modalities are usually not needed in the routine work-up of granulomatous diseases of the chest. In special cases magnetic resonance imaging (MRI) and positron emission tomography (PET)-CT scans play an important role, e. g. detecting cardiac sarcoidosis by cardiac MRI or choline C-11 PET-CT in diagnosing lung carcinoma in scar tissue after tuberculosis. The accuracy of thin-slice CT is very high for granulomatous diseases. In cases of chronic disease and fibrotic interstitial lung disease it is important to perform thin-slice CT in order to diagnose a specific disease pattern. Thin-slice CT is also highly sensitive in detecting disease complications and comorbidities, such as malignancies. Given these indications thin-slice CT is generally accepted in the routine daily practice. A thin-slice CT and an interdisciplinary discussion are recommended in many cases with a suspected diagnosis of pulmonary granulomatous disease due to clinical or radiographic findings. (orig.)

    Full Text Available BACKGROUND: Granulomatous lobular mastitis (GLM is an inflammatory disease of the breast, which can mimic breast cancer in clinical and radiological findings. We conducted the present study in order to determine the diagnostic and other important aspects of this disease. METHODS: In this study, we reviewed the records of 38 patients with granulomatous lobular mastitis in order to describe the clinical, imaging, laboratory, pathologic, and treatment aspects of this disease. RESULTS: All of the patients’ ages were in the range of 22-62 years (mean age: 42 years. All of them had children, history of oral contraceptive pill (OCP usage, antibiotic therapy and mammoplasty. In physical examination, dimpling, edema, inflammation, ulcer, abscess, and firm mass were detected. Size of masses was in the range of 2 × 2 to 8 × 6 cm and their location, in most cases, was in the superior lateral quadrant or central region. In Ultrasonography, a hypoechoic fibroglandular mass and collection, and in pathologic findings, granulomatous reaction was reported. These patients were treated by antibiotics, corticosteroids, and surgery. CONCLUSIONS: GLM is a chronic inflammatory lesion of the breast which can mimic breast cancer. A history of child bearing, lactation, and OCP drug usage have suspicious roles in the formation of GLM. The most common clinical sign in these patients is a painful mass in the breast. We uncovered that clinical and radiological findings are not specific and sufficient for diagnosis of GLM. Therefore, for better diagnosis of this disease, usage of core, incisional, or excisional biopsy are recommended.

    Full Text Available Systemic lupus erythematosus (SLE is a connective tissue disease characterized by the formation of autoantibodies and immune complexes. Lupus nephritis is one of the hallmark features of SLE. CXCL10 is a chemokine secreted by IFNg- stimulated endothelial cells and has been shown to be involved in the pathological processes of autoimmune diseases. The objective was to measure urinary CXCL10 in SLE patients, to compare levels between nephritis and non-nephritis groups and to study its correlation with other variables. Sixty lupus patients were enrolled in our trial. Thirty patients had lupus nephritis and the other 30 were without evidence of lupus nephritis. Thirty healthy subjects were willing to participate as a healthy control group. Renal biopsy was performed for lupus nephritis group. Urinary CXCL10 was measured using the ELISA technique. Serum creatinine, C3, C4 and 24 h urinary proteins were measured. Lupus activity was assessed using systemic lupus erythematosus disease activity index (SLEDAI scoring system. Renal activity was measured using renal activity scoring system. CXCL10 was significantly higher in lupus nephritis patients than in lupus patients without nephritis. CXCL10 was significantly correlated with renal activity score, 24 hours urinary proteins and the SLEDAI score. It is highly valid predictor of SLE nephritis with high sensitivity and specificity. CXCL 10 a highly sensitive and specific non-invasive diagnostic tool for lupus nephritis patients.

    Full Text Available Background: Idiopathic granulomatous mastitis (IGM is an uncommon benign chronic inflammatory breast disease, and erythema nodosum (EN is an extremely rare systemic manifestation of IGM. Here, we report a rare case of IGM accompanied by EN. Case Report: A 32-year-old patient was admitted to our clinic with a history of a tender mass in the right breast. On physical examination, the right breast contained a hard, tender mass in the lower half with in-drawing of the nipple. She had florid EN affecting both legs. She was evaluated with mammography, ultrasound, power Doppler ultrasound, non-enhancing magnetic resonance imaging (MRI, dynamic contrast-enhanced MRI, fine needle aspiration biopsy (FNAB and excisional biopsy. Time-intensity curves showed a type II pattern on dynamic contrast-enhanced MRI, which has an intermediate probability for malignancy. The FNAB reported a benign cytology suggestive of a granulomatous inflammation, which was also supported by the histopathological findings. A partial mastectomy was performed following medical treatment. There was no recurrence at 1-year follow-up. Conclusion: IGM should be considered in the differential diagnosis of EN. Although histopathological examination remains the only method for the definite diagnosis of IGM, MRI can be helpful in the diagnosis or differentiation of benign lesions from malignant ones.

    Pregnancy can be successful in most women with lupus nephritis. Pregnancy in SLE should be planned and a management strategy should be agreed in full consultation with the patient, prior to conception. Women with SLE frequently need treatment throughout pregnancy. It is essential that the maternal disease is well controlled prior to, during and after pregnancy to ensure the best possible outcome for the mother and child.

    Full Text Available The role of the renal biopsy in lupus nephritis is to provide the diagnosis and to define the parameters of prognostic and therapeutic significance for an effective clinicopathological correlation. Various classification schemas initiated by World Health Organization in 1974 have been proposed until the most recent update by International Society of Nephrology/Renal Pathology Society in 2004. In this paper, we reviewed the new classification system with the associated literature to highlight the benefits and the weak points that emerged so far. The great advantage of the classification emerged to provide a uniform reporting for lupus nephritis all over the world. It has provided more reproducible results from different centers. However, the studies indicated that the presence of glomerular necrotizing lesion was no longer significant to determine the classes of lupus nephritis leading to loss of pathogenetic diversity of the classes. Another weakness of the classification that also emerged in time was the lack of discussions related to the prognostic significance of tubulointerstitial involvement which was not included in the classification. Therefore, the pathogenetic diversity of the classification still needs to be clarified by additional studies, and it needs to be improved by the inclusion of the tubulointerstitial lesions related to prognosis.

    Full Text Available The significance of breast tuberculosis is due to rare occurrence and mistaken identity with breast cancer and pyogenic breast abscess. A 70-year-old woman presented with a gradually increasing swelling in the right breast involving the outer upper quadrant since 6 months. Examination of the axilla revealed no lymphadenopathy. FNAC from the lump was inconclusive. Straw-colored discharge from the FNAC site was negative for acid-fast bacilli on Z-N staining and on culture. Modified radical mastectomy was done since malignancy could not be ruled out. Histopathology showed features of granulomatous mastitis. Lymph nodes recovered from the specimen showed caseation necrosis. Anti-tubercular treatment was given to the patient, and she has remained asymptomatic over 1 year of follow-up so far. Extrapulmonary tuberculosis occurring in the breast is extremely rare and is uncommon even in countries where the incidence of pulmonary and extrapulmonary tuberculosis is high.

    Lupus nephritis is a manifestation of SLE resulting from glomerular immune complex deposition and inflammation. Lupus nephritis demonstrates familial aggregation and accounts for significant morbidity and mortality. We completed a meta-analysis of three genome-wide association studies of SLE to identify lupus nephritis-predisposing loci. Through genotyping and imputation, >1.6 million markers were assessed in 2000 unrelated women of European descent with SLE (588 patients with lupus nephritis and 1412 patients with lupus without nephritis). Tests of association were computed using logistic regression adjusting for population substructure. The strongest evidence for association was observed outside the MHC and included markers localized to 4q11-q13 (PDGFRA, GSX2; P=4.5×10(-7)), 16p12 (SLC5A11; P=5.1×10(-7)), 6p22 (ID4; P=7.4×10(-7)), and 8q24.12 (HAS2, SNTB1; P=1.1×10(-6)). Both HLA-DR2 and HLA-DR3, two well established lupus susceptibility loci, showed evidence of association with lupus nephritis (P=0.06 and P=3.7×10(-5), respectively). Within the class I region, rs9263871 (C6orf15-HCG22) had the strongest evidence of association with lupus nephritis independent of HLA-DR2 and HLA-DR3 (P=8.5×10(-6)). Consistent with a functional role in lupus nephritis, intra-renal mRNA levels of PDGFRA and associated pathway members showed significant enrichment in patients with lupus nephritis (n=32) compared with controls (n=15). Results from this large-scale genome-wide investigation of lupus nephritis provide evidence of multiple biologically relevant lupus nephritis susceptibility loci.

    Renal extramedullary hematopoiesis is rarely recognized in the antemortem setting. We identified 14 patients with renal extramedullary hematopoiesis on antemortem specimens from 1994 to 2015. The mean age was 68 years (range 47-87 years); males predominated (M:F=9:5). All presented with renal insufficiency, including five (36%) with acute kidney injury. The mean serum creatinine at biopsy was 2.9 mg/dl (range 1.2-7.3 mg/dl). All had proteinuria (mean 7.9 g/24 h; range 0.5-28; n=13), including 9 with ≥3 g/24 h. Renal extramedullary hematopoiesis appeared histologically as an interstitial infiltrate (n=12) and/or a perirenal infiltrate (n=3) or mass-like lesion (n=1). Five were misdiagnosed as interstitial nephritis. Concurrent glomerular disease was prevalent and included fibrillary-like glomerulonephritis (n=3), chronic thrombotic microangiopathy (n=5), focal segmental glomerulosclerosis (n=6), and diabetic glomerulosclerosis (n=2). All patients had an underlying hematologic malignancy: primary myelofibrosis in 9, myeloproliferative neoplasm not otherwise specified in 1, essential thrombocythemia in 1, polycythemia vera in 1, and plasma cell myeloma in 2. Clinical follow-up was available in 12 patients, mean of 29 months (range 4-120 months). In 10 patients for whom treatment history could be obtained, 9 were treated with chemotherapy, and 1 was treated with steroids. The mean creatinine at last follow-up was 2 mg/dl (range 1.2-3.9 mg/dl) (n=9). Ten patients died in the follow-up period from their underlying hematological disease and had persistent renal disease. The two remaining patients had persistent chronic kidney disease. Renal extramedullary hematopoiesis should be considered in the differential diagnosis of interstitial infiltrates, particularly in the presence of a glomerulopathy and a hematologic malignancy.

    BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and sepsis are commonly treated with intravenous vancomycin. However, vancomycin treatment is associated adverse reactions, including skin rashes and nephrotoxicity. We present a case of acute renal failure due to acute tubulointerstitial nephritis associated with a diffuse leukocytoclastic vasculitic skin eruption following intravenous vancomycin treatment. CASE REPORT A 79-year-old Caucasian male patient was treated with intravenous vancomycin for MRSA bacteremia. Prior to treatment, his creatinine was normal at 0.6 mg/dl. He presented one week later with shortness of breath, lower limb edema, and acute renal failure. He had a diffuse maculopapular rash involving the trunk and both upper and lower extremities. A renal biopsy and left arm skin biopsy were examined histologically. The skin biopsy showed leukocytoclastic vasculitis. Renal biopsy showed some sclerosed glomeruli, some with mesangial proliferation, and tubulointerstitial inflammation with eosinophils and plasma cells and mild interstitial fibrosis. Although there was some renal arteriolosclerosis, no vasculitic changes were seen, and no vascular thrombosis was present. A diagnosis of leukocytoclastic vasculitis and acute tubulointerstitial nephritis secondary to intravenous vancomycin therapy was made. CONCLUSIONS Although skin reactions associated with drug therapy are common, vancomycin-associated dermal vasculitis is rare. Tubulointerstitial nephritis is also a rare association with vancomycin treatment. This case report has highlighted that patients being treated with intravenous vancomycin should be carefully observed for acute skin rashes and deterioration in renal function, which can be managed by ceasing treatment with vancomycin, steroid challenge, and preventing future exposure to similar antimicrobial agents.

    In this study, we aimed to analyze features and outcome of convulsion in pediatric lupus nephritis patients. We retrospectively reviewed data of 14 Iranian children with lupus nephritis who developed seizures and compared them with a group of the same number of well matched pediatric lupus nephritis patients. Higher serum creatinine levels and higher frequencies of anemia and lymphopenia were observed in the convulsion group. Multivariable logistic regression analysis revealed that the only risk factor for development of convulsion in pediatric lupus patients with nephritis was lymphopenia. Survival analysis showed that convulsion had no impact on patient and renal function outcomes in our pediatric lupus nephritis subjects. In conclusion, we found that lymphopenia is a predictive factor for convulsion occurrence in our patients and special attention to neurological status assessment may be needed in this situation.

    Mycophenolate mofetil is an immunosupressive agent used in transplantation and subsequently in a variety of autoimmune conditions. It inhibits both B and T lymphocyte proliferation, and also has nonimmune effects on the kidney. The major experience in systemic lupus erythematosus has focused on proliferative lupus nephritis. In our study we treated 8 female patients with proliferative lupus nefritis with combination therapy of prednisone (1 mg/kg body weight) and mycophenolate mofetil (2 g per day). Complete remission was defined as a value for urinary protein excretion that was less than 0.5 g per 24 hours, with normal urinary sediment, a normal serum albumin concentration and improved or stable serum creatinine. Partial remission was defined as a daily proteinuria below 2 g in a previously nephrotic patient or minimum 30% from starting values, with normal urinary sediment, serum albumin of minimum 30 g/L and stable serum creatinine. Two patients had a complete remission after 7 and 2 months respectively. Five patients had a partial remission after 5.2+/-4.3 months of therapy. One patient did not react on therapy. There were no side effects during the course of therapy. Considering the fact that 7/8 patients have had nephrotic range proteinuria and that 50% of patients were refractory on standard induction therapy, results of this study are good indicator of value of mycophenolate mofetil in the terapy of proliferative forms of lupus nephritis. Mycophenolate mofetil gives satisfactory results in the treatment of proliferative forms of lupus nephritis with minimal side effects.

    Two cases of tubulointerstitial nephritis and uveitis are presented. Immunosuppressive therapy was required to control the uveitis. Contrary to that usually described, uveitis became chronic, which made immunosuppressive therapy necessary. Nephritis was successfully treated with steroids. Tubulointerstitial nephritis and uveitis syndrome is an under-diagnosed disorder and requires clinical suspicion due to there being no specific laboratory study available. Recurrences and relapses of ocular inflammation are common. Immunosuppressive therapy is not often needed. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

    Renal biopsy plays an indispensable role in the diagnosis and management of patients with lupus nephritis (LN). A number of studies have evaluated the role of a repeat biopsy in case of disease relapse or treatment unresponsiveness. We studied 40 patients with LN with renal biopsies performed at baseline and after six months of therapy. The baseline and protocol biopsies were compared with respect to histological class transformation, crescents, tubular atrophy, interstitial fibrosis and glomerulosclerosis. We also compared serum creatinine, hemoglobin, systemic lupus erythematosus disease activity index (SLEDAI) scores, 24-h urine protein excretion and C3levels as well as activity index (AI) and chronicity index (CI) at baseline and at six months. Comparison of means was made by paired t test, McNemar test and marginal homogeneity test (multinomial data). Histological class transformation was seen in 10 patients (25%). Intra-class progression to greater chronicity was seen in 10 other patients (25%).There was an increase in glomerulosclerosis, tubular atrophy, interstitial fibrosis and a reduction in cellularity, crescent formation and wire loop lesions in the protocol biopsy. A decline in AI (6.05 vs. 2.50, P protocol biopsy. Our study shows a trend toward greater chronicity in protocol biopsies in LN.

    Full Text Available Lupus nephritis (LN is involvement of the kidney in patient with systemic lupus erythematosus (SLE and one of the most common target organ in SLE. The diagnosis of LN will significantly impact the clinical outcome and therapy of the patient. Therapy regiment of LN is divided into two stages, induction and maintenance treatment. The main objective of the induction therapy is to achieve complete or partial remission as soon as possible since it is correlated with better prognosis and fewer relapse incidence. In the maintenance stage, the main aim of the therapy is to maintain the remission status and avoid future relapse. It is also important to evaluate the effectiveness of the therapy as it will affect the duration and the regiment therapy being used. Corticosteroid, cyclophosphamide, mycophenolate mofetil, azathrioprine, cyclosporine and tacrolimus are example of drugs used in LN therapy. Currently, studies are being conducted to evaluate and develop targeted drug therapy to further add treatment options for LN.

    Lupus nephritis (LN) is one of the most serious complications of systemic lupus erythematosus (SLE) since it is the major predictor of poor prognosis. In susceptible individuals suffering of SLE, in situ formation and deposit of immune complexes (ICs) from apoptotic bodies occur in the kidneys as a result of an amplified epitope immunological response. IC glomerular deposits generate release of proinflammatory cytokines and cell adhesion molecules causing inflammation. This leads to monocytes and polymorphonuclear cells chemotaxis. Subsequent release of proteases generates endothelial injury and mesangial proliferation. Presence of ICs promotes adaptive immune response and causes dendritic cells to release type I interferon. This induces maturation and activation of infiltrating T cells, and amplification of Th2, Th1 and Th17 lymphocytes. Each of them, amplify B cells and activates macrophages to release more proinflammatory molecules, generating effector cells that cannot be modulated promoting kidney epithelial proliferation and fibrosis. Herein immunopathological findings of LN are reviewed. PMID:22536486

    Full Text Available Granulomatous lung diseases are a heterogeneous group of disorders that have a wide spectrum of pathologies with variable clinical manifestations and outcomes. Precise clinical evaluation, laboratory testing, pulmonary function testing, radiological imaging including high-resolution computed tomography and often histopathological assessment contribute to make a confident diagnosis of granulomatous lung diseases. Differential diagnosis is challenging, and includes both infectious (mycobacteria and fungi and noninfectious lung diseases (sarcoidosis, necrotising sarcoid granulomatosis, hypersensitivity pneumonitis, hot tub lung, berylliosis, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, rheumatoid nodules, talc granulomatosis, Langerhans cell histiocytosis and bronchocentric granulomatosis. Bronchoalveolar lavage, endobronchial ultrasound-guided transbronchial needle aspiration, transbronchial cryobiopsy, positron emission tomography and genetic evaluation are potential candidates to improve the diagnostic accuracy for granulomatous lung diseases. As granuloma alone is a nonspecific histopathological finding, the multidisciplinary approach is important for a confident diagnosis.

    We aim to review the imaging appearance of granulomatous lesions of the head and neck. Granulomatous lesions are seen in different regions of the head and neck and a difficult diagnostic challenge for the radiologist. Infective granulomas may be due to bacterial or fungal agents. Non-infective granulomas are Wegener's granulomatosis, sarcoidosis, amyloidosis, chemical granuloma and reparative giant cell granuloma. Familiarity with the clinical presentation and imaging features of these lesions can suggest diagnosis in some cases. CT and MR imaging demonstrate the exact location, extension and effect on surrounding structures. A thorough knowledge of age, gender, common location, clinical features and imaging appearance of granulomatous lesions are important for diagnosis.

    Amoebiasis is a common cause of liver disease usually presenting as single large or multiple smaller abscesses. Cases with granulomatous hepatitis have rarely been described. We report the case of a 7-year-old girl with amoebic granulomatous hepatitis in which multiple liver absecces were deomstrated by MRI. A total of 14 abscesses were identified, ranging from 5 mm to 3 cm in diameter. The largest lesions appeared to T2-weighted images as heterogeneous, low-intensity areas surrounded by a double-layered wall, the inner layer of which was hyperintense and the outer layer hypointense. These signs, which have never been described in classic amoebic abscess, represent, we believe, a pattern of hepatic granulomatous amoebiasis lesions. We suggest that MRI should always be performed in cases of amoebic infection. (orig.)

  7. Lupus Nephritis: The Evolving Role of Novel Therapeutics

    Immune complex accumulation in the kidney is the hallmark of lupus nephritis and triggers a series of events that result in kidney inflammation and injury. Cytotoxic agents and corticosteroids are standard of care for lupus nephritis treatment, but are associated with considerable morbidity and suboptimal outcomes. Recently, there has been interest in using novel biologic agents and small molecules to treat lupus nephritis. These therapies can be broadly categorized as anti-inflammatory (laquinamod, anti–tumor necrosis factor–like weak inducer of apotosis, anti-C5, and retinoids), antiautoimmunity (anti-CD20, anti–interferon α, and costimulatory blockers), or both (anti–interleukin 6 and proteasome inhibitors). Recent lupus nephritis clinical trials applied biologics or small molecules of any category to induction treatment, seeking short-term end points of complete renal response. These trials in general have not succeeded. When lupus nephritis comes to clinical attention during the inflammatory stage of the disease, the autoimmune stage leading to kidney inflammation will have been active for some time. The optimal approach for using novel therapies may be to initially target kidney inflammation to preserve renal parenchyma, followed by suppression of autoimmunity. In this review, we discuss novel lupus nephritis therapies and how they fit into a combinatorial treatment strategy based on the pathogenic stage. PMID:24411715

    Full Text Available Patrick FK Yong1,2, David P D’Cruz21Department of Clinical Immunology, Kings College Hospital; 2The Lupus Research Unit, St Thomas’ Hospital, London, UKAbstract: Lupus nephritis is a complication of systemic lupus erythematosus, which has significant morbidity and mortality. The accepted standard of treatment for severe lupus nephritis is cyclophosphamide for induction of remission. This has significant adverse effects including severe infection and amenorrhea. In addition, although cyclophosphamide induces remission, long-term mortality does not seem to be altered. Mycophenolate mofetil (MMF is an immunosuppressive agent originally used in solid organ transplantation, which has been compared with cyclophosphamide in trials for lupus nephritis. Randomized trials with MMF have been relatively small, although pooled data seem to suggest that it is at least as effective as cyclophosphamide in inducing remission. In addition, MMF has also been associated with a reduced risk of infection and amenorrhea, although this finding is not universal. MMF appears to be associated with more diarrhea compared with cyclophosphamide. MMF is likely to be a useful treatment for lupus nephritis, although available trial data are limited due to the small size of previous studies. A large trial (the Aspreva Lupus Management Study is currently underway to attempt to establish the place of MMF in treatment of lupus nephritis.Keywords: mycophenolate mofetil, lupus nephritis, systemic lupus erythematosus

    To determine the frequency of granulomatous inflammation on histopathological findings amongst cancer patients and correlating them with tuberculosis. Methods: The retrospective review was conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised medical records of cancer patients with a histopathological finding of granulomatous inflammation between January 2010 and December 2015. Data was reviewed, including clinical history, availability of acid fast bacilli stain on tissue and mycobacterium tuberculosis culture results. Data related to treatment, duration and outcomes was also reviewed and was analysed using SPSS 19. Results: Out of 28690 cancer patients during the study period, 17345(60.4%) had undergone biopsy for different reasons, and of those, 78 (0.45%) had granulomatous inflammation and formed the study sample. Among them, 40(51.3%) patients had caseous granulomatous inflammation while 38 (48.7%) had non-caseous granulomas. Acid fast bacillus tissue stain was performed on 77(98.7%) patients, of whom only 9 (11.5%) specimens showed acid fast bacilli. Mycobacterium tuberculosis culture was performed on 53(68%) specimens and among them 13(16.7%) grew mycobacterium tuberculosis. Anti-tuberculosis treatment was offered to 38 (48.7%) patients, including those with positive AFB stain and MTB culture results. Of them, 32(41%) patients completed the treatment while 4(5.1%) defaulted and 2(2.6%) died. Symptomatic and radiological improvement was observed in 16(20.5%) patients. Conclusion: Granulomatous inflammation was infrequently encountered in cancer patients. Mycobacterium tuberculosis cultures assisted in definitive decision-making but granulomatous inflammation could not be anticipated when the specimens were initially processed except when visible caseation was encountered. Processing specimens for mycobacterium tuberculosis cultures when caseation was encountered may be a reasonable strategy to adopt. (author)

    It has been 50 years since chronic granulomatous disease was first reported as a disease which fatally affected the ability of children to survive infections. Various milestone discoveries from the insufficient ability of patients' leucocytes to destroy microbial particles to the underlying genetic predispositions through which the disease is inherited have had important consequences. Longterm antibiotic prophylaxis has helped to fight infections associated with chronic granulomatous disease while the steady progress in bone marrow transplantation and the prospect of gene therapy are hailed as long awaited permanent treatment options. This review unearths the important findings by scientists that have led to our current understanding of the disease.

    Granulomatous slack skin syndrome is a rare variant of cutaneous T-cell lymphoma (mycosis fungoides). It is characterized clinically by redundant skin folds, which show a predilection towards flexural areas such as the axilla and the groin. Histologically, it shows a granulomatous T-cell infiltrate and loss of elastic tissue. It has an indolent but progressive course; and is usually refractory to treatment. We report a unique case of slack skin syndrome, sparing the classical sites with rapid and unusual involvement of non-intertriginous areas.

    Background/Objective B-cell activating factor (BAFF) plays an important role in the pathogenesis of systemic lupus erythematosus. However, the role of BAFF in lupus nephritis (LN) is not understood. Our aim was to evaluate the expression of BAFF and its three receptors in renal biopsy samples from patients with LN and investigate a relationship with pathological class. Methods We conducted a prospective descriptive study (2011-2014) on 52 kidney biopsy samples from patients with LN. Immunohistochemistry for BAFF, its receptors (transmembrane activator and calcium modulator and cyclophilin ligand interaction (TACI), protein maturation of B cells (BCMA), and BAFF-receptor (BAFF-R)), and CD20 expression was performed. Samples were scored according to the percentage of cells with positive expression. Results In class II LN, BAFF-R and TACI were not expressed, whereas BCMA and BAFF were lowly expressed in the interstitial inflammatory infiltrates. Proliferative class III/IV had elevated BAFF expression in the glomeruli, and TACI was expressed in interstitial inflammatory infiltrates and the glomeruli. Interestingly, the class IV cases with vasculopathy ( n = 4) had endothelial BAFF expression, which was not visible in thrombotic microangiopathy ( n = 4). Class V was characterized by low BAFF expression in interstitial inflammatory infiltrates and by BAFF, TACI, and BCMA expression in the glomeruli. BAFF expression was associated with inflammatory scores and CD20 positive infiltrates, mainly in class IV. Conclusions Expression patterns of BAFF and its receptors differ according to LN class. Our study provides evidence that BAFF could be used as a routine marker in LN biopsies and to determine which patients will benefit from anti-BAFF therapy.

    We report the case of a 45-year-old Colombian female with a 3-month history of headache, anorexia, fatigue, and diplopia in addition to left facial nerve palsy 2 weeks prior to presentation. On examination, visual fields and fundi were normal, but left abducens and facial nerve palsies were noted. An MRI scan disclosed a sellar mass with suprasellar but neither parasellar nor retrosellar extension. The mass was interpreted as a pituitary tumor and resected via the transsphenoidal approach. Histologic examination revealed necrotizing granulomas in a background of normal pituitary gland tissue. The differential diagnosis includes tuberculosis, sarcoidosis, fungal infection, syphilis, granulomatous autoimmune hypophysitis, Langerhans cell histiocytosis, and Erdheim-Chester disease. Staining for tubercle bacilli (acid fast and fite) as well as for fungi (GMS) was negative and PCR for mycobacteria showed the same result. Postoperative empiric treatment with antituberculous medication resulted in resolution of the cranial nerve palsies within a 1 month. The diagnosis of inflammatory/infectious granulomatous hypophysitis can be difficult to diagnose preoperatively and occasionally even postoperatively. A high index of suspicion should be maintained especially in those patients with a history of a systemic granulomatous disease or in regions endemic in granulomatous infectious diseases.

    The most commonly used dermal fillers are hyaluronic acids (HAs), and in general, are well tolerated with mild to moderate risk of adverse events. The most frequently reported side effects are injection site erythema and bruising. We present the first case of a patient who developed a severe granulomatous foreign body reaction to the HA filler, Belotero Balance. In our review of the literature, a granulomatous reaction has never before been reported as a side effect of this particular HA filler (1). On exam, the patient had firm erythematous, granulomatous plaques on her bilateral cheeks, with a tender, fluctuant nodule on her right cheek. Complete resolution of this delayed reaction was achieved after several injections of intralesional Kenalog (IL-K) 2.5 mg/cc, and further fine-tuning was achieved through laser resurfacing. Granulomatous reactions can occur with any HAs, though such incidents are not commonly reported. These delayed reactions are generally localized immunological reactions, though biofilm infections should be excluded where appropriate. It is only with long-term (5-year) longitudinal studies that accurate numbers of such reactions will be known.

    Granulomatous dermatitis has been associated with hematologic disorders, including the myelodysplastic syndromes. We describe the first case of granulomatous dermatitis associated with polycythemia vera, presenting as large erythematous nodules mimicking panniculitis. We also present the seventh case associated with myelodysplasia, with erythematous plaques on the face and neck, similar to a neutrophilic dermatosis. We consider it particularly interesting for dermatologists to be aware of this dermatosis as a nonspecific manifestation of various hematologic disorders. We suggest performing additional tests (complete blood count) to exclude the possibility that the skin manifestations are the initial sign of hematologic disease. Furthermore, we propose using the broader term, granulomatous dermatitis, to refer to these disorders as, although there are more reports of interstitial forms, cases with a more nodular presentation have also been published, and the importance of the diagnosis derives not from the subtype but from the relationship with an underlying disease.

    Coexistence of lung cancer and granulomatous inflammation in the same patient confuses clinicians. We aimed to document the prevalence, clinicopathological features, treatment outcomes and prognosis in patients with coexisting granulomatous inflammation undergoing curative lung resection for lung cancer, in a tuberculosis (TB)-endemic country. An observational cohort study of patients with lung cancer undergoing curative resection between 2012 and 2015 in a tertiary centre in Singapore. One hundred and twenty-seven patients underwent lung resection for cancer, out of which 19 (14.9%) had coexistent granulomatous inflammation in the resected specimen. Median age was 68 years and 58.2% were males. Overall median (range) survival was 451 (22-2452) days. Eighteen (14%) patients died at median duration of 271 days after surgery. The postsurgery median survival for those alive was 494 (29-2452) days in the whole group. Subgroup analysis did not reveal any differences in age, gender, location of cancer, radiological features, type of cancer, chemotherapy, history of TB or survival in patients with or without coexistent granulomatous inflammation. Incidental detection of granulomatous inflammation in patients undergoing lung resection for cancer, even in a TB-endemic country, may not require any intervention. Such findings may be due to either mycobacterial infection in the past or 'sarcoid reaction' to cancer. Although all patients should have their resected specimen sent for acid-fast bacilli culture and followed up until the culture results are reported, the initiation of the management of such patients as per existing lung cancer management guidelines does not affect their outcome adversely.

    Full Text Available Systemic lupus erythematosus is common in our country, and renal involvement is an important cause of chronic kidney disease. This study was aimed at comparing the three regimens, i.e., cyclophosphamide-based regimes (low dose and high dose and mycophenolate mofetil (MMF-based regime and determining if cyclophosphamide (CPM-based regime can be an effective, safe, and cheap alternative to MMF-based regime in a resource-limited setting. Out of 144 patients, females constituted 89%. Nephrotic nephritic presentation was the most common. Rapidly progressive renal failure was seen in in 42 (29.1% patients. Class IV was the most common 66 (45.8% histological class. Crescentic glomerulonephritis was seen in 18 (12.5%. Overall remission (complete + partial at 6 months was seen in 71.4% in National Institute of Health regime, 65% in European lupus nephritis trial protocol and 72.9% in MMF regime. End-stage renal disease and switching to other therapies were comparable among the three groups. Although infections were more with CPM, the difference was not statistically significant. CPM-based therapies were associated with a significantly lower cost.

    Although the survival of patients with lupus nephritis (LN) has improved considerably in recent years, refractory LN appears in a substantial proportion of patients and, therefore, treatment of LN remains a real challenge today. We will use the term "refractory" LN, for those cases with none or partial response to first-line therapies. In this sense, numerous epidemiological factors, including racial, socioeconomic, histological and serological parameters, may influence treatment response and, therefore, may have an impact on the outcome of renal involvement. Initial conventional therapy will depend somewhat on these epidemiological factors. If this initial therapy fails, fortunately today we have alternative therapies that include the multitarget therapy and the use of biologics. Published evidence about these therapies is presented in this review. Important terms in the management of LN, such as the definition of complete response, partial response, sustained response and renal flare as well as the discrimination of different types of flare, are also discussed here according to the European consensus statement on the terminology used in the management of lupus glomerulonephritis.

    The rationale and results for interstitial therapies via interventional MRI in the treatment of tumors in various regions are presented. Different interstitial treatment techniques are presented based on varying technologies both for tumor ablation and treatment monitoring. Data are presented based on 335 patients, 29-84 years of age (mean age 59 years, 196 men and 139 women) with a total of 932 liver tumors, 16 head and neck tumors and 14 abdominal recurrent pelvic and lymphatic tumors. All lesions had been treated with MR-guided laser-induced interstitial thermotherapy (LITT) via 2516 laser applications and 1856 cannulations. Data in the literature are extremely varying depending on author experience, treatment technique, and the included patient material. In our patient material we were able to achieve a local tumor control of 96.7 % depending on the size of the tumorous lesion, the topographical relationship, and the applied laser parameters. The overall cumulative survival rate of patients with liver metastases was 45.74 months (median 40.97 months, 95 % confidence interval 31.42-50.52). The cumulative survival rate of the patient group with hepatic metastases of colorectal carcinoma was 42.71 months (median 39.33 months, 95 % confidence interval 33.26-45.37). In patients with head and neck tumors a relevant reduction in clinically relevant symptoms such as pain, swallowing disorders, or nervous compression was achieved in 11 of 15 patients treated with LITT. In 14 soft tissue tumors, such as pelvic tumor recurrence and lymph node metastases, a local tumor control was obtained in 68 % of lesions. Interstitial therapies under interventional MRI guidance, such as LITT, results in a high local tumor control with an improved survival rate. (orig.) With 7 figs., 28 refs.

    The natural course of systemic lupus erythematosus (SLE) is characterized by periods of disease activity and remissions. Prolonged disease activity results in cumulative organ damage. Lupus nephritis is one of the most common and devastating manifestations of SLE. In the era of changing therapy to less toxic regimens, some authors have stated that if mycophenolate mofetil can be used for the induction and maintenance treatment in all histological classes of lupus nephritis, renal biopsy can be omitted. This article aims to answer the question of what brings the bigger risk: renal biopsy or its abandonment.

Radiologists also reviewed the cases of 40 patients with various diagnoses to assess the accuracy of the interstitial line sign. US showed a definite gestational sac in four of the 12 patients (33%); the rest had a heterogeneous mass in the cornual region. Thinning of the myometrial mantle was seen in these four patients. The gestational sac appeared eccentric in three of these but in only three of 12 (25%) overall. The endometrial canal or interstitial portion of the tube was identified in 11 of 12 patients (92%). The interstitial line had better sensitivity (80%) and specificity (98%) than eccentric gestational sac location (sensitivity, 40%; specificity, 88%) and myometrial thinning (sensitivity, 40%; specificity, 93%) for the diagnosis of interstitial ectopic pregnancy. The interstitial line sign is a useful diagnostic sign of interstitial ectopic pregnancy.

    Full Text Available Intravesical immunotherapy with attenuated strains of Mycobacterium bovis is a widely used therapeutic option in patients with non-muscle-invasive transitional cell carcinoma of the bladder. A rare complication of intravesical therapy with the Bacillus Calmette-Guérin vaccine is granulomatous prostatitis, which due to increasing levels of prostate-specific antigen and abnormalities found in transrectal examination of the prostate may suggest concomitant prostate cancer. A case of extensive granulomatous prostatitis in a 61-year-old patient which occurred after the first course of a well-tolerated Bacillus Calmette-Guérin therapy is presented. Due to abnormalities found in rectal examination and an abnormal transrectal ultrasound image of the prostate with extensive infiltration mimicking neoplastic hyperplasia a core biopsy of the prostate was performed. Histopathological examination revealed inflammatory infiltration sites of tuberculosis origin.

    Idiopathic granulomatous mastitis (IGM) is a rare inflammatory condition of the breast. The etiology and treatments options of IGM remain controversial. Previous case reports have suggested that Corynebacterium sp., a gram-positive bacillus endogenous to the skin, may be associated with IGM. In the present report, we describe the first case of IGM with a positive culture for Corynebacterium sp. reported in the United States.

  16. Somatostatin Negatively Regulates Parasite Burden and Granulomatous Responses in Cysticercosis

    Full Text Available Cysticercosis is an infection of tissues with the larval cysts of the cestode, Taenia  solium. While live parasites elicit little or no inflammation, dying parasites initiate a granulomatous reaction presenting as painful muscle nodules or seizures when cysts are located in the brain. We previously showed in the T. crassiceps murine model of cysticercosis that substance P (SP, a neuropeptide, was detected in early granulomas and was responsible for promoting granuloma formation, while somatostatin (SOM, another neuropeptide and immunomodulatory hormone, was detected in late granulomas; SOM’s contribution to granuloma formation was not examined. In the current studies, we used somatostatin knockout (SOM−/− mice to examine the hypothesis that SOM downmodulates granulomatous inflammation in cysticercosis, thereby promoting parasite growth. Our results demonstrated that parasite burden was reduced 5.9-fold in SOM−/− mice compared to WT mice (P<0.05. This reduction in parasite burden in SOM−/− mice was accompanied by a 95% increase in size of their granulomas (P<0.05, which contained a 1.5-fold increase in levels of IFN-γ and a 26-fold decrease in levels of IL-1β (P<0.05 for both compared to granulomas from WT mice. Thus, SOM regulates both parasite burden and granulomatous inflammation perhaps through modulating granuloma production of IFN-γ and IL-1β.

  17. Circadian rhythm in experimental granulomatous inflammation is modulated by melatonin.

    Biological rhythms are detected in a variety of physiological and pathological conditions in man and animals, such as rheumatoid arthritis and asthma. Here we describe a circadian rhythm in experimental infectious and non-infectious granuloma. After 30 days of BCG (Bacillus Calmette-Guerin) or nystatin inoculation in the left hind foot of C57B1/6 mice, there is an oscillation with a period of approximately 24 hr in the variation of paw thickness, indicating a circadian rhythm. The acrophase occurred during the light phase, between 9:00 and 13:00 hr, while the nadir occurred in the dark phase, between 21:00 and 01:00 hr. The vascular permeability around the granulomatous lesions was higher at 12:00 hr than at 24:00 hr. This is in agreement with the observation that the thickness of a paw with granulomatous lesion is larger during the light phase. This rhythmic variation was eliminated by either pinealectomy or superior cervical ganglionectomy, which greatly reduce melatonin levels in the blood. Nocturnal replacement of melatonin in pinealectomized mice led to the re-establishment of the circadian rhythm. Thus, the rhythm of the granulomatous lesion is due to the rhythmic melatonin release by the pineal gland. This approach opens new questions regarding the modulation of chronic inflammation in inflammatory diseases that present rhythmic symptoms throughout the day.

  18. Interstitial pregnancy: role of MRI

    We report the MRI features of two cases of interstitial pregnancy. In both cases, MRI was able to localize the ectopic pregnancy by showing a gestational structure surrounded by a thick wall in the upper part of the uterine wall separated from the endometrium by an uninterrupted junctional zone. Because US may confuse angular and interstitial pregnancies and because interstitial pregnancy has a particular evolutive course, MR imaging may play a key role in the diagnosis and management of women with interstitial pregnancy.

    Despite the development of new modalities, cyclophosphamide (CYC) remains the preferred initial treatment for severe proliferative lupus nephritis. Controversies continue about the best route, dosage, and duration of CYC treatment. For recalcitrant disease, new immunosuppressive and immunomodulating agents, immunoablative high dose CYC, nucleoside analogues, apheresis, and the biological response modifiers can be considered.

    Full Text Available Pregnancy in patients with lupus nephritis is a challenging clinical situation. Although not absolutely contraindicated, it is associated with increased risk for foetal and maternal complications, including foetal loss, preterm delivery, intrauterine growth retardation, hypertension, pre-eclampsia, nephritis flare, and, rarely, maternal death. The complication rate is further increased in the presence of antiphospholipid antibodies or the antiphospholipid syndrome. Proliferative classes of nephritis (III and IV also appear to confer excess risk for complications. Immunosuppressives such as cyclophosphamide and mycophenolate, and antihypertensives such as angiotensin-converting-enzyme (ACE inhibitors and angiotensin receptor blockers need to be stopped due to teratogenic effects. Agents like corticosteroids, azathioprine, and probably calcineurin inhibitors are considered compatible with gestation. Lupus activity needs to be assessed and carefully monitored. Thrombotic risk due to antiphospholipid antibodies, thrombotic events, or nephrosis needs to be evaluated and managed accordingly, with the use of aspirin and/or unfractioned or low molecular weight heparin. Differentiating between severe pre-eclampsia and lupus nephritis flare might require a renal biopsy, which might not always be feasible, for example after the 32nd gestational week or in a setting of uncontrolled hypertension or thrombocytopaenia. A 6-month history of quiescent disease on non-teratogenic agents seems to be associated with best chance for favourable outcomes. Pregnancy is optimally managed by a multidisciplinary team of experienced specialists, and close monitoring for disease activity during gestation; additionally, follow-up for maternal flare postpartum is also advised.

Renal disease (glomerulonephritis is one of the most frequent and serious manifestations of SLE. Of the various histological types of lupus glomerulonephritis, diffuse proliferative nephritis carries the worst prognosis. Combined with high-dose prednisone, mycophenolate mofetil (MMF has emerged as a first-line immunosuppressive treatment, although data regarding the efficacy of MMF on the long-term preservation of renal function are forthcoming. Cyclophosphamide is reserved for more severe forms of lupus nephritis, such as crescentic glomerulonephritis with rapidly deteriorating renal function, patients with significant renal function impairment at presentation, and refractory renal disease. Evidence for the calcineurin inhibitors in the treatment of lupus nephritis is weaker, and it concerns patients who are intolerant or recalcitrant to other agents. While further controlled trials are mandatory, B cell modulation therapies, such as rituximab, belimumab and epratuzumab are confined to refractory disease. Non-immunosuppressive measures, such as angiotensin-converting enzyme inhibitors, vigorous blood pressure control, prevention and treatment of hyperlipidemia and osteoporosis, are equally important.Keywords: lupus, nephritis, nephropathy, glomerulonephritis, treatment, therapy, women

    Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder that has a broad spectrum of effects on the majority of organs, including the kidneys. Approximately 40-70% of patients with SLE will develop lupus nephritis. Renal assault during SLE is initiated by genes that breach immune tolerance and promote autoantibody production. These genes might act in concert with other genetic factors that augment innate immune signalling and IFN-I production, which in turn can generate an influx of effector leucocytes, inflammatory mediators and autoantibodies into end organs, such as the kidneys. The presence of cognate antigens in the glomerular matrix, together with intrinsic molecular abnormalities in resident renal cells, might further accentuate disease progression. This Review discusses the genetic insights and molecular mechanisms for key pathogenic contributors in SLE and lupus nephritis. We have categorized the genes identified in human studies of SLE into one of four pathogenic events that lead to lupus nephritis. We selected these categories on the basis of the cell types in which these genes are expressed, and the emerging paradigms of SLE pathogenesis arising from murine models. Deciphering the molecular basis of SLE and/or lupus nephritis in each patient will help physicians to tailor specific therapies.

    To investigate factors predictive of future lupus nephritis development when systemic lupus erythematosus (SLE) is diagnosed. Patients with newly diagnosed SLE without renal manifestations were followed for development of lupus nephritis, comparing findings at baseline between those who did or did not develop nephritis. Albumin-to-globulin ratio (AGR) was calculated as albumin/(total protein-albumin). Cox proportional hazard model was used to identify predictors of lupus nephritis. Of 278 patients, 241 did not and 37 did develop lupus nephritis during follow-up. On univariate analysis, young age, low C3, low C4, high anti-dsDNA titre, anti-Sm antibody, anti-RNP antibody and low AGR were associated with a higher risk of lupus nephritis. On multivariate analysis, factors predictive of nephritis were age [adjusted hazard ratio (aHR) 0.928, 95% confidence interval (CI): 0.895-0.961, p lupus nephritis development. Young age, low C3, high anti-dsDNA titre and presence of anti-Sm antibody at diagnosis of SLE were associated with a risk of future lupus nephritis, but the hazard was greatest with a low AGR value, suggesting that a greater proportion of immunoglobulin relative to total protein is associated with the development of nephritis.

    Inhalation of beryllium (Be) has been associated with 2 syndromes: an acute chemical pneumonitis and a granulomatous lung disease known as chronic beryllium disease (CBD). The purpose of this study was to establish a mouse model of CBD using the inhalation route of exposure. A/J (H-2a haplotype) and C3H/HeJ (H-2{sup k}) Mice were exposed once for 90 min in nose-only exposure tubes to aerosols of Be metal. Six mo later, lung histopathologic responses were assessed. Further analyses defined the phenotypic profile of lymphocytes in pulmonary lesions and evaluated proliferation of lymphocytes in situ and in response to Be in vitro. Responses were similar in both strains of mice. Most Be-exposed mice had minimal to mild interstitial fibrosis. The majority of lymphocytes in interstitial infiltrates and in microgranulomas were CD4+ T cells. Interstitial compact aggregates of lymphocytes contained B cells centrally and CD4+ cells peripherally. Lymphocyte labeling indices, used to assess proliferation in situ, were significantly greater within microgranulomas compared to compact lymphocytic aggregates. Lymphocyte stimulation indices in response to BeSO{sub 4} in vitro were not positive in blood, spleen, or tracheobronchial lymph node samples. Be-specific immune responses and nonspecific inflammatory responses to toxic and foreign-body properties of Be may have contributed to the histopathology in both strains of mice. The interstitial mononuclear cell infiltrates, presence of microgranulomas, multinucleated foreign-body and Langhans giant cells, interstitial fibrosis, and CD4+ T-cell predominance with local proliferation are features similar to CBD in humans. The chronic lung disease induced in these mice by inhaled Be can be used to investigate the importance of variables such as dose, exposure pattern, and physicochemical form of Be in producing this disease. 29 refs., 6 figs., 3 tabs.

    Pulmonary nocardiosis is a granulomatous disease with high mortality that affects both immunosuppressed and immunocompetent patients. The mechanisms leading to the establishment and progression of the infection are currently unknown. An animal model to study these mechanisms is sorely needed. We report the first in vivo model of granulomatous pulmonary nocardiosis that closely resembles human pathology. BALB/c mice infected intranasally with two different doses of GFP-expressing Nocardia brasiliensis ATCC700358 (NbGFP), develop weight loss and pulmonary granulomas. Mice infected with 109 CFUs progressed towards death within a week while mice infected with 108 CFUs died after five to six months. Histological examination of the lungs revealed that both the higher and lower doses of NbGFP induced granulomas with NbGFP clearly identifiable at the center of the lesions. Mice exposed to 108 CFUs and subsequently to 109 CFUs were not protected against disease severity but had less granulomas suggesting some degree of protection. Attempts to identify a cellular target for the infection were unsuccessful but we found that bacterial microcolonies in the suspension used to infect mice were responsible for the establishment of the disease. Small microcolonies of NbGFP, incompatible with nocardial doubling times starting from unicellular organisms, were identified in the lung as early as six hours after infection. Mice infected with highly purified unicellular preparations of NbGFP did not develop granulomas despite showing weight loss. Finally, intranasal delivery of nocardial microcolonies was enough for mice to develop granulomas with minimal weight loss. Taken together these results show that Nocardia brasiliensis microcolonies are both necessary and sufficient for the development of granulomatous pulmonary nocardiosis in mice. PMID:27303806

    2017-07-01

    Interstitial cystitis (IC) is a progressive bladder disorder that presents with symptoms of bladder urgency, frequency and pain. The aetiology of the disease remains uncertain, but it is postulated that there is an initial infective insult which damages the glycosaminoglycan (GAG) layer of the bladder urothelium. This defect allows an influx of ions, particularly potassium, which initiates an inflammatory reaction in the bladder wall, which incites the symptoms described above. Treatment initially involves behavioural and oral medication, with second line being intravesical instillation therapy. Treatment strategies focus on restoring lower urinary tract epithelial function, inhibiting neural activation, controlling allergies and relieving symptoms. In this review, current intravesical therapy will be discussed, as well as what lies on the horizon for intravesical therapy in IC.

    2015-01-01

    Full Text Available Autoimmune nephritis triggered by metallic ions was assessed in a Long-Evans rat model. The parameters evaluated included antinuclear autoantibody production, kidney damage mediated by immune complexes detected by immunofluorescence, and renal function tested by retention of nitrogen waste products and proteinuria. To accomplish our goal, the animals were treated with the following ionic metals: HgCl2, CuSO4, AgNO3, and Pb(NO32. A group without ionic metals was used as the control. The results of the present investigation demonstrated that metallic ions triggered antinuclear antibody production in 60% of animals, some of them with anti-DNA specificity. Furthermore, all animals treated with heavy metals developed toxic glomerulonephritis with immune complex deposition along the mesangium and membranes. These phenomena were accompanied by proteinuria and increased concentrations of urea. Based on these results, we conclude that metallic ions may induce experimental autoimmune nephritis.

Conflicting data exist as to the possible renal origin of apoptotic cells in SLE patients with nephritis. We assessed the level of renal cell apoptosis in kidney...... for tubulointerstitial mononuclear cell infiltration than patients without apoptotic tubular cells in their biopsies (P = 0.01). Furthermore, the level of tubular cell apoptosis displayed a statistically significant, positive correlation with the activity index score for mononuclear cell infiltration (r(s) = 0.472, P...... = 0.004) but not with scores for other activity or chronicity index components. These observations indicate that the degree of tubular cell apoptosis correlates with the severity of tubulointerstitial inflammation in SLE-associated nephritis. However, our findings do not suggest that apoptotic renal...

    Abstract Rationale: The simultaneous occurrence of pyoderma gangrenosum (PG) and chronic granulomatous disease (CGD) is uncommon and few cases have been reported worldwide. Patient concerns: PG is a rare, chronic, ulcerative, neutrophilic skin disease of unknown etiology that requires immunosuppressive treatment. CGD belongs to Primary Immune Deficiencies in which the main defect lies in an inability of the phagocytic cells to generate superoxide making patients susceptible to serious, potentially life-threatening bacterial and fungal infections. Diagnoses: In this manuscript, we present a case of ulcerative pyoderma gangrenosum in a 28-year-old man with recent diagnosis of chronic granulomatous disease during hospitalization for resistant pulmonary tuberculosis complicated with Aspergillus infection. Interventions: Second-line therapy with dapsone and intravenous immunoglobulin was initially administered but eventually corticosteroids were added to treatment because of disease progression and further ulceration. Outcomes: Patient's ulcers were gradually healed with no side effects. Lessons: Corticosteroids could be used under close monitoring for the treatment of PG in a patient with CGD, despite the increased risk for infections. PMID:28767612

    Henoch–Schönlein purpura is a systemic vasculitis characterized by IgA deposits, which target the skin, joints, and kidneys, among other organs. In children, prognosis is often good but little is known about biomarkers of pediatric nephritis. We hypothesized that biological markers, including cytokines, immunoglobulins, IgA-immune complexes, IgA glycosylation and neutrophil gelatinase-associated lipocalin (NGAL), may discriminate IgA vasculitis (IgAV) pediatric patients with renal involvement from those without renal involvement. Fifty children at the time of IgAV rash between 2010 and 2015 were prospectively enrolled and compared to 21 controls. All patients were assessed for clinical and biological parameters at the time of diagnosis, including the levels of cytokines, immunoglobulins, immune complexes, IgA glycosylation and NGAL in serum and urine. Among IgAV patients, 33 patients exhibited nephritis (IgAV-N) and 17 children were without nephritis (IgAV-woN). The serum level of galactose-deficient (Gd)-IgA1 (pmarkers, urinary IgA and IgM had the highest AUC (0.86 and 0.87 respectively, p<0.0001). This prospective cohort study furthers our understanding of the pathophysiology of IgAV. We identified biomarkers that are able to distinguish patients initially with or without nephritis. To conclude, serum Gd-IgA1 and urinary IgA, IgG, IgM, IL-6, IL-8, IL-10, and IgA-IgG and IgA-sCD89 complexes could identify IgAV pediatric patients with renal involvement at the time of diagnosis.

    A 12-year-old Congolese girl presented with acute renal failure, edema, hypertension, hemoptysis, hematuria, and proteinuria after a history of throat infection. Renal ultrasound showed kidneys of normal size, with increased echogenicity of the cortical parenchyma and decreased corticomedullary differentiation. Other additional investigations showed pancytopenia with decreased complement (low C3 and C4). Antinuclear antibodies were strongly positive, including anti-double stranded DNA. Renal biopsy confirmed severe grade IV lupus nephritis. She was treated with high-dose steroids, mycophenolate mofetil and hydroxychloroquine, in addition to hemodialysis. After one week of intensive treatment, diuresis recovered and dialysis could be stopped after six sessions. We describe an uncommon case of severe lupus nephritis, presenting with terminal renal failure. Since the rarity of this disease presentation, other more common diagnoses have to be considered. Once the diagnosis of lupus nephritis is established, a choice has to be made between the different induction treatment protocols. The patient's ethnic background and other supportive therapies, such as the need for dialysis, can help to make this choice.

    Full Text Available Abstract Introduction Legionnaires' disease is recognized as a multi-systemic illness. Afflicted patients may have pulmonary, renal, gastrointestinal tract and central nervous system complications. However, renal insufficiency is uncommon. The spectrum of renal involvement may range from a mild and transient elevation of serum creatinine levels to anuric renal failure requiring dialysis and may be linked to several causes. In our present case report, we would like to draw attention to the importance of the pathological documentation of acute renal failure by reporting a case of a patient with acute tubulointerstitial nephritis complicating Legionnaires' disease. Case presentation A 55-year-old Caucasian man was admitted to our hospital for community-acquired pneumonia complicated by acute renal failure. Legionella pneumophila serogroup type 1 was diagnosed. Although the patient's respiratory illness responded to intravenous erythromycin and ofloxacin therapy, his renal failure worsened, he became anuric, and hemodialysis was started. A renal biopsy was performed, which revealed severe tubulointerstitial nephritis. After initiation of steroid therapy, his renal function improved dramatically. Conclusions This case highlights the importance of kidney biopsies in cases where acute renal failure is a complicating factor in Legionnaires' disease. If the presence of acute tubulointerstitial nephritis can be confirmed, it will likely respond favorably to steroidal treatment and thus irreversible renal damage and chronic renal failure will be avoided.

    To assess the activity of lupus nephritis, 43 patients with systemic lupus erythematosus (SLE) were studied by gallium imaging. Delayed renal visualization 48 hours after the gallium injection, a positive result, was noted in 25 of 48 scans. Active renal disease was defined by the presence of hematuria, pyuria (10 or more red blood cells or white blood cells per high-power field), proteinuria (1 g or more per 24 hours), a rising serum creatinine level, or a recent biopsy specimen showing proliferative and/or necrotizing lesions involving more than 20 percent of glomeruli. Renal disease was active in 18 instances, inactive in 23, and undetermined in seven (a total of 48 scans). Sixteen of the 18 scans (89 percent) in patients with active renal disease showed positive findings, as compared with only four of 23 scans (17 percent) in patients with inactive renal disease (p less than 0.001). Patients with positive scanning results had a higher rate of hypertension (p = 0.02), nephrotic proteinuria (p = 0.01), and progressive renal failure (p = 0.02). Mild mesangial nephritis (World Health Organization classes I and II) was noted only in the patients with negative scanning results (p = 0.02) who, however, showed a higher incidence of severe extrarenal SLE (p = 0.04). It is concluded that gallium imaging is a useful tool in evaluating the activity of lupus nephritis

    Abstract Background: Integrative medicine is claimed to improve symptoms of lupus nephritis. No systematic reviews have been performed for the application of integrative medicine for lupus nephritis on patients with systemic lupus erythematosus (SLE). Thus, this review will aim to evaluate the current evidence on the efficacy of integrative medicine for the management of lupus nephritis in patients with SLE. Methods and analyses: The following electronic databases will be searched for studies published from their dates of inception February 2018: Medline, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL), as well as 6 Korean medical databases (Korea Med, the Oriental Medicine Advanced Search Integrated System [OASIS], DBpia, the Korean Medical Database [KM base], the Research Information Service System [RISS], and the Korean Studies Information Services System [KISS]), and 1 Chinese medical database (the China National Knowledge Infrastructure [CNKI]). Study selection, data extraction, and assessment will be performed independently by 2 researchers. The risk of bias (ROB) will be assessed using the Cochrane ROB tool. Dissemination: This systematic review will be published in a peer-reviewed journal and disseminated both electronically and in print. The review will be updated to inform and guide healthcare practice and policy. Trial registration number: PROSPERO 2018 CRD42018085205 PMID:29595669

    Interstitial cystitis, or painful bladder syndrome, is a chronic inflammatory disease of a bladder of unknown etiology. It negatively affects the quality of life, causes depressive disorders, anxiety, and sexual dysfunction. Despite numerous studies, the etiology of interstitial cystitis is still unclear and it’s considered as painful bladder syndrome with multifactorial origin.

    To validate clinical indices of lupus nephritis activity and damage when used in children against the criterion standard of kidney biopsy findings. In 83 children requiring kidney biopsy, the Systemic Lupus Erythematosus Disease Activity Index renal domain (SLEDAI-R), British Isles Lupus Assessment Group index renal domain (BILAG-R), Systemic Lupus International Collaborating Clinics (SLICC) renal activity score (SLICC-RAS), and SLICC Damage Index renal domain (SDI-R) were measured. Fixed effects and logistic models were calculated to predict International Society of Nephrology/Renal Pathology Society (ISN/RPS) class; low-to-moderate versus high lupus nephritis activity (National Institutes of Health [NIH] activity index [AI]) score: ≤10 versus >10; tubulointerstitial activity index (TIAI) score: ≤5 versus >5; or the absence versus presence of lupus nephritis chronicity (NIH chronicity index) score: 0 versus ≥1. There were 10, 50, and 23 patients with ISN/RPS class I/II, III/IV, and V, respectively. Scores of the clinical indices did not differentiate among patients by ISN/RPS class. The SLEDAI-R and SLICC-RAS but not the BILAG-R differed with lupus nephritis activity status defined by NIH-AI scores, while only the SLEDAI-R scores differed between lupus nephritis activity status based on TIAI scores. The sensitivity and specificity of the SDI-R to capture lupus nephritis chronicity was 23.5% and 91.7%, respectively. Despite being designed to measure lupus nephritis activity, SLICC-RAS and SLEDAI-R scores significantly differed with lupus nephritis chronicity status. Current clinical indices of lupus nephritis fail to discriminate ISN/RPS class in children. Despite its shortcomings, the SLEDAI-R appears best for measuring lupus nephritis activity in a clinical setting. The SDI-R is a poor correlate of lupus nephritis chronicity. © 2016, American College of Rheumatology.

  10. Inhibition of sphingosine kinase-2 in a murine model of lupus nephritis.

    Directory of Open Access Journals (Sweden)

    Ashley J Snider

    Full Text Available Sphingosine-1-phosphate (S1P, a potent bioactive lipid, is emerging as a central mediator in inflammation and immune responses. We have previously implicated S1P and its synthetic enzyme sphingosine kinase (SK in inflammatory and autoimmune disorders, including inflammatory bowel disease and rheumatoid arthritis. Generation of S1P requires phosphorylation of sphingosine by SK, of which there are two isoforms. Numerous studies have implicated SK1 in immune cell trafficking, inflammation and autoimmune disorders. In this study, we set out to determine the role of SK and S1P in lupus nephritis (LN. To this end, we examined S1P and dihydro-S1P (dh-S1P levels in serum and kidney tissues from a mouse model of LN. Interestingly dh-S1P was significantly elevated in serum and kidney tissue from LN mice, which is more readily phosphorylated by SK2. Therefore, we employed the use of the specific SK2 inhibitor, ABC294640 in our murine model of LN. Treatment with ABC294640 did not improve vascular or interstitial pathology associated with LN. However, mice treated with the SK2 inhibitor did demonstrate decreases in glomerular pathology and accumulation of B and T cells in the spleen these were not statistically different from lpr mice treated with vehicle. LN mice treated with ABC294640 did not have improved urine thromboxane levels or urine proteinuria measurements. Both S1P and dh-S1P levels in circulation were significantly reduced with ABC294640 treatment; however, dh-S1P was actually elevated in kidneys from LN mice treated with ABC294640. Together these data demonstrate a role for SKs in LN; however, they suggest that inhibition of SK1 or perhaps both SK isoforms would better prevent elevations in S1P and dh-S1P and potentially better protect against LN.

    2012-01-01

    Chronic granulomatous disease (CGD) is the most common inherited disorder of phagocytic functions, caused by genetic defects in the leukocyte nicotinamide dinucleotide phosphate (NADPH) oxidase. Consequently, CGD phagocytes are impaired in destroying phagocytosed microorganisms, rendering the patients susceptible to bacterial and fungal infections. Besides this immunodeficiency, CGD patients suffer from various autoinflammatory symptoms, such as granuloma formation in the skin or urinary tract and Crohn-like colitis. Owing to improved antimicrobial treatment strategies, the majority of CGD patients reaches adulthood, yet the autoinflammatory manifestations become more prominent by lack of causative treatment options. The underlying pathomechanisms driving hyperinflammatory reactions in CGD are poorly understood, but recent studies implicate reduced neutrophil apoptosis and efferocytosis, dysbalanced innate immune receptors, altered T-cell surface redox levels, induction of Th17 cells, the enzyme indolamine-2,3-dioxygenase (IDO), impaired Nrf2 activity, and inflammasome activation. Here we discuss immunological mechanisms of hyperinflammation and their potential therapeutic implications in CGD. PMID:21808651

    Conclusion: Detection of TB in tissue slides is still based on the histological pattern of the granuloma, which has several differential diagnoses with different treatments. Presence of mycobacterial antigens and tissue morphology can be evaluated using the IHC technique. Considering the criteria of positive IHC staining of TB granulomatous reactions, this stain not only highlights the presence of mycobacterial antigens for tissue diagnosis, but also could morphologically localize their distribution in different cells. Pathologists must be familiar with adequate staining pattern, elimination of background staining, and type of selected antibody. This method is especially important for application in countries with high prevalence of TB as a technique with early diagnostic value in tissue specimens. Early diagnosis using this technique can reduce related morbidity and mortality and decrease the rate of complications due to misdiagnosis and mistreatment of TB.

    Full Text Available Classic type of pyoderma gangrenosum (PG is an uncommon ulceronecrotic cutaneous disease of uncertain aetiology characterised by broad zones of confluent ulceration with violaceous undermined margins. Some 50% of cases are associated with systemic diseases. The superficial granulomatous variant of pyoderma gangrenosum (SGPG of the external genitalia is extremely rare Patients with this condition develop single or multiple ulcerated skin lesions often with sinus tract formation. The majority of these lesions were found on the trunk and limbs. SGPG is less likely to be associated with underlying disease processes than classic PG. We present a 58 year-old with recalcitrant penile ulceration demonstrated to be SGPG on biopsy. Although rare and poorly recognised, the histological features are sufficiently typical to allow the correct diagnosis to be established.

    Full Text Available Idiopathic granulomatous mastitis (IGM is a rare chronic inflammatory disease of the breast, and its etiology remains not fully elucidated. IGM is observed more often in patients with autoimmune disease. Hyperprolactinemia is observed during pregnancy, lactation, and a history of oral contraceptive use. A 39-year-old patient with no history of oral contraceptive use presented with complaints such as redness, pain, and swelling in her left breast. Ultrasound and magnetic resonance imaging (MRI revealed a suspicious inflamed mass lesion. Core biopsy was performed to exclude breast cancer and to further diagnose. The breast abscess was drained and steroids were given for treatment. In order to monitor any progression during the three months of treatment, hormone levels were routinely examined. Prolactin level was above the reference range, and pituitary MRI revealed a pituitary prolactinoma. After treatment with prolactin inhibitors, IGM also improved with hyperprolactinemia. This report emphasizes attention to hyperprolactinemia in cases of IGM diagnosis and treatment.

    The contribution of computed tomography (CT), ultrasound (US), and nuclear medicine studies in the evaluation and management of seven patients with chronic granulatous disease was retrospectively reviewed. These modalities proved valuable in detecting sites of infection, particularly in the abdomen. Three patients had liver abscesses, two had suppurative retroperitoneal lymphadenopathy, one had empyema, and one hand a scrotal abscess. Furthermore, CT or US-guided percutaneous aspiration and/or drainage of infected material was successfully performed on three separate occasions in a single patient, obviating the need for surgery. The newer imaging modalities are useful in the prompt diagnosis and in some instances non-operative therapy of complications of chronic granulomatous disease. (orig.)

    We report a rare case of diffuse tracheo-bronchitis as a complication of Crohn's disease. A young man with a long-standing history of Crohn's enterocolitis initially presented with epigastric pain and melena. Upper endoscopy revealed erythematous, edematous, and friable mucosa with erosions, particularly in the pyloric channel, causing gastric outlet obstruction, and a nonbleeding ulcer in the corpus of stomach. Biopsy of these lesions showed chronic gastritis and a noncaseating epithelioid granuloma, consistent with active Crohn's disease. The patient was treated with a course of corticosteroids and the gastric symptoms resolved. A few months later, he developed fever, cough, hemoptysis, and rash. Bronchoscopy demonstrated a markedly thickened and very inflamed trachea with extensive friable, whitish lesions and ulcerations. Histology showed severe noncaseating granulomatous inflammation. The patient improved with a 6-week oral, followed by an additional 4-week inhaled, corticosteroid treatment. Since then, he has been doing well without relapse of pulmonary symptoms for 2 years.

    About 75% of cutaneous lymphomas belong to the group of T-cell lymphomas. Mycosis fungoides is the most common entity in this group. Granulomatous slack skin is a rare form of cutaneous T-cell lymphoma closely related to mycosis fungoides. We present here a patient with areas of lax skin for several years who developed a generalized erythroderma with associated immunoactivation and a deterioration in his general condition. This report discusses clinically and histologically the differential diagnoses, namely granulomatous slack skin and granulomatous mycosis fungoides, and suggests that these 2 disorders are only variants in the broad spectrum of a single disease.

    Full Text Available Interstitial cystitis, or painful bladder syndrome, is a chronic inflammatory disease of a bladder of unknown etiology. It negatively affects the quality of life, causes depressive disorders, anxiety, and sexual dysfunction. Despite numerous studies, the etiology of interstitial cystitis is still unclear and it’s considered as painful bladder syndrome with multifactorial origin. According to the US National Health and Nutrition Examination Survey, 470/100 000 people (60/100 000 men, 850/100 000 women are diagnosed with interstitial cystitis. Diagnosis of the disease is difficult and is substantially based on clinical symptoms. Pelvic pain, urinary urgency, frequency and nocturia are the basic complaints in this pathology. The diagnosis requires exclusion of diseases with similar manifestations. So interstitial cystitis is frequently misdiagnosed as urinary tract infection, overactive bladder, urethral obstruction or diverticulosis, chronic prostatitis, bladder cancer, vulvodynia, endometriosis, and chronic pelvic pain. Etiopathogenesis of the disease is uncertain, which makes etiologic treatment impossible. Currently scientific discussions on the causes of disease continue as well as different treatment regimens are offered, but are often ineffective, palliative and temporary. The treatment for intersticial cystitis should focus on restoring normal bladder function, prevention of relapse of symptoms and improvement of patients’ quality of life. The literature review presents current view on the terminology, epidemiology, diagnosis and treatment of interstitial cystitis.

    Full Text Available To evaluate the efficacy and safety of the monthly pulse IV cyclophosphamide (IVC therapy in patients with severe lupus nephritis, we studied 39 patients of lupus nephritis on IVC therapy between 1998 to 2002. Single monthly cyclophosphamide (0.75-1 g/m² was infused intravenously with oral prednisolone (0.5 mg/kg per day and appropriate hydration. Of the 39 pa-tients 25 (86.2% patients were females and 4 (13.8% were males. Six (2% cases had irregular follow-up and 3 patients had expired during the initial cycles and were excluded from the study. The mean age was 25.6 + 6.72 years (range 10-40 years. The mean duration of the disease from the onset to renal biopsy was 24.2 + 18.5 months. The clinical presentations included nephrotic syndrome (34.5%, acute glomerulonephritis (31.0%, Pyrexia of unknown origin (PUO (10.3%, and rapidly progressive renal failure (6.7%. Renal insufficiency was present in 47.2% cases. Twenty-two (75.9% patients had diffuse proliferative glomerulonephritis (class IV, 6 (20.7% focal proliferative glomerulonephritis (class III, and one (3.4% class Vd. After a mean follow-up of 15.8 months, out of 29 patients, 13 (44.8% had achieved complete remission, 7 (24.1% partial remission and 9 (31.0% cases did not respond to the therapy. Side effects of the therapy included vomiting and nausea (100% and hair loss during the first few doses of IVC. In addition, one case had dysfunctional uterine bleeding and two patients had avascular necrosis of femoral head. We conclude that our data indicate that IVC in severe lupus nephritis is effective in Indian patients though longer follow-up is required.

    Aim We aim to describe the pattern of response to treatment in a cohort of Egyptian lupus nephritis (LN) patients and to define variable prognostic factors. Methods We retrospectively analyzed records of 928 systemic lupus erythematosus (SLE) patients (898 females, 30 males) with biopsy-confirmed LN seen between 2006 and 2012 at Cairo University hospitals. Results Our study involved 928 SLE patients with a mean age of 26.25 ± 6.487 years, mean LN duration at time of renal biopsy 6.48 ± 4.27 months, mean SLEDAI 28.22 ± 11.7, and mean follow-up duration of 44.14 ± 17.34 months. Induction treatment achieved remission in 683 patients. Remission was achieved in all 32 patients with class II LN, compared to 651/896 (72.7%) patients in classes III, IV, and V. Induction by intravenous (IV) cyclophosphamide achieved response in 435/575 (75.7%) patients, while induction by mycophenolate mofetil (MMF) resulted in response in 216/321 (67.3%) patients ( p = 0.0068). Nephritic flares were least observed when MMF was used for maintenance (30/239 (12.6%) patients), compared to 71/365 patients (19.5%) ( p = 0.0266) when azathioprine (AZA) was used, and 22/79 patients (27.8%) ( p = 0.002) with IV cyclophosphamide. Class IV LN, high chronicity index, presence of crescents, and interstitial fibrosis in biopsies were all associated with chronic kidney disease (CKD) development eventually ( p < 0.001, p = 0.005, p = 0.012, and p = 0.031, respectively). By the end of the study duration, 305 (32.7%) patients had CKD. Logistic regression detected that high baseline serum creatinine, failure to achieve remission, hypertension, and nephritic flare were the main risk factors for poor renal outcome ( p < 0.001, p < 0.001, p = 0.004, and p < 0.001, respectively). The 5 years' mortality was 69 (7.4%) patients with sepsis being the main cause of death. Conclusion IV cyclophosphamide superseded as induction treatment, while MMF was

    Most cases of granulomatous reaction to Descemet membrane are caused by disciform herpes simplex and mycotic keratitis. To our knowledge, a clinicopathologic report of Acanthamoeba species infection has not been documented. We used standard histopathologic techniques, including light microscopy with special stains and indirect immunofluorescence. A granulomatous reaction with many multinucleated giant cells, some of which engulfed cysts of Acanthamoeba species, was present in the posterior corneal stroma and anterior chamber along the plane of Descemet membrane. A severe, acute, suppurative inflammatory response and areas of stromal necrosis also were present. The diagnosis of Acanthamoeba castellanii was confirmed by immunofluorescent studies. A granulomatous reaction to Descemet membrane and/or the corneal stroma may represent a specific tissue response to various infectious agents. Keratitis caused by Acanthamoeba species may be added to herpes simplex stromal keratitis and mycotic keratitis as a causative organism capable of producing a granulomatous reaction involving the stroma and anterior chamber.

    Pneumocystis jirovecii pneumonia (PCP) continues to be a leading cause of morbidity and mortality in kidney transplant recipients. Granulomatous PCP is an unusual histological presentation that has been described in a variety of immunosuppressive conditions. Previous studies have demonstrated an association between granulomatous disorders and hypercalcemia, the purported mechanism of which is extrarenal production of 1,25-dihydroxyvitamin D by activated macrophages. Here, we report a case of granulomatous formation in a kidney transplant recipient with PCP who presented with hypercalcemia and suppressed parathyroid hormone, both of which resolved after successful treatment of the pneumonia. In immunocompromised patients, pulmonary infection associated with hypercalcemia should raise the suspicion of PCP and other granulomatous disorders. © 2014 John Wiley & Sons A/S.

    Ten patients with lupus nephritis and marked proteinuria (3.9 g or more/d) that did not respond adequately to treatment with prednisone alone or prednisone in combination with azathioprine were treated with total lymphoid irradiation in an uncontrolled feasibility study. Within 6 weeks after the start of total lymphoid irradiation, the serum albumin level rose in all patients in association with a reduction in the serum level of anti-DNA antibodies, an increase in the serum complement level, or both. Improvement in these variables persisted in eight patients followed for more than 1 year, with the stabilization or reduction of the serum creatinine level. Urinary leakage of albumin was substantially reduced in all patients. Side effects associated with radiotherapy included transient constitutional complaints in ten patients, transient blood element depressions in three, localized viral and bacterial infections in four, and ovarian failure in one. The results suggest that total lymphoid irradiation may provide an alternative to cytotoxic drugs in the treatment of lupus nephritis.

    Full Text Available Abstract Epimorphin modulates epithelial morphogenesis in embryonic mouse organs. We previously suggested that epimorphin contributes to repair of bleomycin-induced pulmonary fibrosis in mice via epithelium-mesenchyme interactions. To clarify the role of epimorphin in human lungs, we evaluated epimorphin expression and localization in normal lungs, lungs with nonspecific interstitial pneumonia (NSIP, and lungs with usual interstitial pneumonia (UIP; we also studied the effect of recombinant epimorphin on cultured human alveolar epithelial cells in vitro. Northern and Western blotting analyses revealed that epimorphin expression in NSIP samples were significantly higher than those in control lungs and lungs with UIP. Immunohistochemistry showed strong epimorphin expression in mesenchymal cells of early fibrotic lesions and localization of epimorphin protein on mesenchymal cells and extracellular matrix of early fibrotic lesions in the nonspecific interstitial pneumonia group. Double-labeled fluorescent images revealed expression of matrix metalloproteinase 2 in re-epithelialized cells overlying epimorphin-positive early fibrotic lesions. Immunohistochemistry and metalloproteinase activity assay demonstrated augmented expression of metalloproteinase induced by recombinant epimorphin in human alveolar epithelial cells. These findings suggest that epimorphin contributes to repair of pulmonary fibrosis in nonspecific interstitial pneumonia, perhaps partly by inducing expression of matrix metalloproteinase 2, which is an important proteolytic factor in lung remodeling.

    Chronic granulomatous disease (CGD) is a congenital immunodeficiency, characterised by significant infections due to an inability of phagocyte to kill catalase-positive organisms including certain fungi such as Aspergillus spp. Nevertheless, other more rare fungi can cause significant diseases. This report is a systematic review of all published cases of non-Aspergillus fungal infections in CGD patients. Analysis of 68 cases of non-Aspergillus fungal infections in 65 CGD patients (10 females) published in the English literature. The median age of CGD patients was 15.2 years (range 0.1-69), 60% of whom had the X-linked recessive defect. The most prevalent non-Aspergillus fungal infections were associated with Rhizopus spp. and Trichosporon spp. found in nine cases each (13.2%). The most commonly affected organs were the lungs in 69.9%. In 63.2% of cases first line antifungal treatment was monotherapy, with amphotericin B formulations being the most frequently used antifungal agents in 45.6% of cases. The overall mortality rate was 26.2%. Clinicians should take into account the occurrence of non-Aspergillus infections in this patient group, as well as the possibility of a changing epidemiology in fungal pathogens. Better awareness and knowledge of these pathogens can optimise antifungal treatment and improve outcome in CGD patients. © 2013 Blackwell Verlag GmbH.

    Chronic granulomatous disease(CGD) is a group of genetic disorders characterized by recurrent pyogenic infections of the respiratory tract, skin, and soft tissue. The aim of this study is to describe the radiological findings of CGD. We retrospectively analyzed radiological findings of 11 patients of CGD, which were diagnosed by nitroblue tetrazolium test. We analyzed the pattern of pneumonia on chest radiograph in all infants. Three cases of chest CT and one case of digital subtraction angiography were performed. According to infant's symptom, abdominal ultrasonography(n = 8), abdominal CT(n = 5), simple bone radiography(n = 2), and brain CT (n = 1) were performed. Repeated infiltration(100%), mass-like consolidation(73%), hilar or mediastinal lymph node largement(64%), scattered nodules(55%), cavity formation(27%), and pleural effusion(27%) were found on the chest radiographs(n = 11) and CT(n = 3). On the abdominal imagings(n = 8), there were hepatosplenomegaly(n = 6), calcification in the liver(n = 2) and kidney(n = 1), hepatic granuloma(n = 1) and renal abscess(n = 1). Two patients had osteomyelitis. There were findings of meningitis on brain CT(n 1). We believe that the combinations of these radiological findings may suggest the diagnosis of CGD in patients with history of reccurent infection

    Lupus nephritis is identified in up to 75% of patients with juvenile systemic lupus erythematosus and may present with abnormal urinary findings (overt lupus nephritis) or be apparent only upon renal biopsy (silent lupus nephritis). We investigated whether serum complement levels correlate with renal pathology in pediatric patients with silent lupus nephritis. We performed baseline renal biopsy in 45 children diagnosed with juvenile systemic lupus erythematosus who were admitted to Kagoshima University Hospital between January 2000 and June 2015. Patients were classified as having overt or silent lupus nephritis based on urinary findings at renal biopsy. Silent lupus nephritis was identified in 55.5% (25/45) of cases. Of these, 6 (13.3%) were classified as class III nephritis, according to the International Society of Nephrology/Renal Pathology Society criteria. Decreased serum C3 levels were associated with the renal pathology classification for patients with silent but not with overt lupus nephritis. No differences in serum C4 levels were identified between cases of silent and overt lupus nephritis. Baseline renal biopsy is a critical component of the work-up of juvenile systemic lupus erythematosus as treatable renal pathology may be present in the absence of urinary signs. Serum C3 may be an important marker of the progression of silent lupus nephritis.

    Full Text Available Our aim in this study is to report the long-term renal outcome of a cohort of Saudi children with systemic lupus erythematosus (SLE. All patients with childhood lupus nephritis (cLN proved by renal biopsy seen between January 2000 and June 2015 were reviewed. The renal outcome was assessed according to serum creatinine level, protein/creatinine ratio at the last follow-up visit, and/or evidence of renal impairment during follow-up period and end-stage renal disease (ESRD. Additional outcome measures include accrual damage measured by pediatric adaptation of the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (pSDI, and death related to SLE was determined. A total of 84 (72 females cLN patients with follow-up duration of 9.3 years (±5.2 were included in this study. The mean current age was 19.4 years (±5.5 and mean age at onset was 9.2 years (±2.4. The most frequent histopathological class was proliferative glomerulonephritis (64.3% followed by membranous nephritis (27.4%. The mean activity and chronicity indices were 5.9 (±3.9 and 2.9 (±2.2, respectively. Renal microthrombosis was found in 9 (10.7% patients. All patients treated with immunosuppressive medications; cyclophosphamide used in 64 followed by mycophenolate mofetil in 42, then azathioprine in 19 patients, while rituximab used in 24 patients. At the last follow-up visit, the mean serum creatinine was 147 umol/L (±197 and the mean protein/ creatinine ratio was 0.8 (± 1.1 while the mean total pSDI was 1.9 (±1.9 and mean renal SDI was 0.7 (±1.1. Sixteen (19% patients had ESRD and eight of them had class IV nephritis. However, there was no significant difference in ESRD by histological class. The overall survival rates were five years: 94% and 10 years: 87%. Infection was the leading cause of mortality. Our patients had severe cLN and required intensive treatment. Despite the survival rate is comparable to other studies, ESRD is more

    Microwave ablation also called interstitial hyperthermia is a medical procedure used in the treatment of many cancers, cardiac arrhythmias and other medical conditions. With this medical therapy, an electromagnetic source (antenna) is directly positioned in the target tissue and a sufficient power is injected to necrosis the tissue. The aim of this study is to propose a design procedure and develop the associated tools, for determining the optimal shape, dimensions, type and operating frequency of antenna according to the target volume. In this context, a 3D numerical predictive model of temperature elevation induced by the electric fields and two benches for thermal and electrical tissues properties characterization have been developed. To validate the procedure and the different tools, an experimental bench test which includes interstitial antenna, external microwave generator, phantom that represents the target tissue and measurement system of temperature and electric field has been elaborated.

    Retrospective clinical analysis. To delineate the clinical presentation of melioidosis in the spine and to create awareness among healthcare professionals, particularly spine surgeons, regarding the diagnosis and treatment of melioidotic spondylitis. Melioidosis is an emerging disease, particularly in developing countries, associated with a high mortality rate. Its causative pathogen, Burkholderia pseudomallei , has been labeled as a bio-terrorism agent. We performed a retrospective analysis of patients who were culture positive for B. pseudomallei . Assessment of patients was performed using clinical, radiological, and blood parameters. Clinical measures included pain, neurological deficit, and return to work. Radiological measures included plain radiography of the spine and magnetic resonance imaging. Blood tests included erythrocyte sedimentation rate and C-reactive protein levels. Four patients having melioidosis with spondylitis were evaluated. All of them had diabetes mellitus; three had multiple abscesses which required incision and drainage. Their clinical spectrum was similar to that of tuberculous spondylitis; all had back pain and radiology revealed infective spondylodiscitis with prevertebral and paravertebral collections with psoas abscess. Three patients underwent ultrasound-guided drainage of the psoas abscess and one had aspiration of the subcutaneous abscess. Bacteriological cultures showed presence of B. pseudomallei , and histopathology showed non-caseating granulomatous inflammation. All patients were treated with intravenous Ceftazidime for 2 weeks, followed by oral bactrim double strength and Doxycycline for 20 weeks. All patients improved with treatment and were healed at follow up. Melioidosis presents with a clinical spectrum similar to that of tuberculosis. A diagnosis of melioidotic spondylitis should be considered, particularly in patients with diabetes with neutrophilic leukocytosis and clinical-radiological features suggestive of

    2011-01-01

    Full Text Available Lupus nephritis (LN is a major clinical manifestation of systemic lupus erythematosus (SLE. Although numerous abnormalities of immune system have been proposed, cytokine overexpression plays an essential role in the pathogenesis of LN. In the initial phase of the disease, the immune deposits and/or autoantibodies induce cytokine production in renal resident cells, leading to further inflammatory cytokine/chemokine expression and leukocyte infiltration and activation. Then, infiltrate leukocytes, such as macrophages (Mφ and dendritic cells (DCs, secrete a variety of cytokines and activate naïve T cells, leading the cytokine profile towards T helper (Th1, Th2, and/or Th17. Recent studies revealed these inflammatory processes in experimental animal models as well as human LN. The cytokine targeted intervention may have the therapeutic potentials for LN. This paper focuses on the expression of cytokine and its functional role in the pathogenesis of LN.

    We report a case of a 65-year-old man who developed an acute illness with fever, arthralgia and nephritic syndrome. Antinuclear antibodies were slightly positive and complement levels were low. Renal biopsy showed exudative diffuse proliferative endocapillary glomerulonephritis with diffuse immunoglobulin (IgG, IgA, IgM) and complement deposition (C3d, C4d, C1q) on immunofluorescence. The patient was first treated with corticosteroids and mycophenolate mofetil for suspected lupus with WHO class IV glomerulonephritis. The diagnosis was questioned and a diagnosis of parvovirus B19-associated nephritis was made based on elevation of serum IgM antibodies for parvovirus B19 and detection of parvovirus B19 DNA on renal biopsy. The immunosuppressive treatment was stopped and progressive spontaneous regression of clinical and laboratory abnormalities was observed. We conclude that human parvovirus B19 infection should be considered as a cause of lupus-like symptomatology and acute glomerulonephritis.

    Full Text Available Enteric fever is a common infectious disease of the tropical world, about 80% of these cases occur in Asian countries. Enteric fever presenting with isolated cerebellar ataxia or nephritis is rare. We report three cases of enteric fever that presented with these complications. Isolated cerebellar ataxia usually occurs in the second week, whereas in our cases it presented within first four days of fever. The common complications of enteric fever related to the urinary tract are cystitis, pyelitis, and pyelonephritis. Glomerulonephritis is uncommon. Most patients with enteric glomerulonephritis present with acute renal failure, hypertensive encephalopathy, or nephritic syndrome. In comparison, our case had milder manifestations. All three patients were treated with parenteral ceftriaxone and showed a prompt recovery.

  5. Interstitial guidance of cancer invasion.

    2012-01-01

    Cancer cell invasion into healthy tissues develops preferentially along pre-existing tracks of least resistance, followed by secondary tissue remodelling and destruction. The tissue scaffolds supporting or preventing guidance of invasion vary in structure and molecular composition between organs. In the brain, the guidance is provided by myelinated axons, astrocyte processes, and blood vessels which are used as invasion routes by glioma cells. In the human breast, containing interstitial collagen-rich connective tissue, disseminating breast cancer cells preferentially invade along bundled collagen fibrils and the surface of adipocytes. In both invasion types, physical guidance prompted by interfaces and space is complemented by molecular guidance. Generic mechanisms shared by most, if not all, tissues include (i) guidance by integrins towards fibrillar interstitial collagen and/or laminins and type IV collagen in basement membranes decorating vessels and adipocytes, and, likely, CD44 engaging with hyaluronan; (ii) haptotactic guidance by chemokines and growth factors; and likely (iii) physical pushing mechanisms. Tissue-specific, resticted guidance cues include ECM proteins with restricted expression (tenascins, lecticans), cell-cell interfaces, and newly secreted matrix molecules decorating ECM fibres (laminin-332, thrombospondin-1, osteopontin, periostin). We here review physical and molecular guidance mechanisms in interstitial tissue and brain parenchyma and explore shared principles and organ-specific differences, and their implications for experimental model design and therapeutic targeting of tumour cell invasion.

    Systemic lupus erythematosus, characterized by persistent inflammation, is a complex autoimmune disorder with no known cure. Immunosuppressants used in treatment put patients at a higher risk of infections. New knowledge of disease modulators, such as symbiotic bacteria, can enable fine-tuning of parts of the immune system, rather than suppressing it altogether. Dysbiosis of gut microbiota promotes autoimmune disorders that damage extraintestinal organs. Here we report a role of gut microbiota in the pathogenesis of renal dysfunction in lupus. Using a classical model of lupus nephritis, MRL/lpr, we found a marked depletion of Lactobacillales in the gut microbiota. Increasing Lactobacillales in the gut improved renal function of these mice and prolonged their survival. We used a mixture of 5 Lactobacillus strains (Lactobacillus oris, Lactobacillus rhamnosus, Lactobacillus reuteri, Lactobacillus johnsonii, and Lactobacillus gasseri), but L. reuteri and an uncultured Lactobacillus sp. accounted for most of the observed effects. Further studies revealed that MRL/lpr mice possessed a "leaky" gut, which was reversed by increased Lactobacillus colonization. Lactobacillus treatment contributed to an anti-inflammatory environment by decreasing IL-6 and increasing IL-10 production in the gut. In the circulation, Lactobacillus treatment increased IL-10 and decreased IgG2a that is considered to be a major immune deposit in the kidney of MRL/lpr mice. Inside the kidney, Lactobacillus treatment also skewed the Treg-Th17 balance towards a Treg phenotype. These beneficial effects were present in female and castrated male mice, but not in intact males, suggesting that the gut microbiota controls lupus nephritis in a sex hormone-dependent manner. This work demonstrates essential mechanisms on how changes of the gut microbiota regulate lupus-associated immune responses in mice. Future studies are warranted to determine if these results can be replicated in human subjects.

    Full Text Available BackgroundThe immune regulatory properties of semaphorin3A (sema3A (both innate and adaptive are well established in many in vitro studies. The injection of sema3A into a mice model of rheumatoid arthritis was proven to be highly beneficial, both in attenuating clinical symptoms and in decreasing inflammatory mechanisms.ObjectivesThis study was designed in order to assess the possible therapeutic benefits of sema3A following its injection into female NZB/W mice.MethodsForty-eight NZB/W mice were recruited for this study. Thirty mice were treated as a “prevention group” and 18 were used as a “treatment group.” Eight-week-old mice were acclimated and then divided into the two abovementioned groups.ResultsThe injection of sema3A into young mice (at week 12 before the onset of disease (the prevention group delayed the appearance of proteinuria. Here, the median time to severe proteinuria was 110 days, 95% CI: 88–131. However, in mice in which the empty vector was injected, the median time to severe proteinuria was 63 days, 95% CI: 0–139. sema3A treatment, significantly reduced renal damage, namely, it prevented the deposition of immune complexes in the glomeruli. When sema3A was injected at the onset of proteinuria (the treatment group, aiming to treat rather than to prevent disease in these mice, survival was increased and the deterioration of proteinuria was delayed.ConclusionSemaphorin3A is highly beneficial in reducing lupus nephritis in NZB/W mice. It delays the appearance and deterioration of proteinuria, and increases the survival rates in these mice. The regulatory mechanisms of sema3A involve both innate and adaptive immune responses. Further studies will establish the idea of applying sema3A in the treatment of lupus nephritis.

    Full Text Available Background. The subclinical pathophysiology of proliferative lupus nephritis (PLN has not been fully elucidated. Myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA is associated with PLN, but prediagnostic levels have not been reported. Methods. We performed a retrospective case-control Department of Defense Serum Repository (DoDSR study comparing MPO-ANCA levels in longitudinal prediagnostic serum samples for 23 biopsy confirmed proliferative lupus nephritis (PLN patients to DoDSR identified age, sex, race, and age of serum matched healthy and SLE without LN disease controls. We also compared the temporal relationship of MPO-ANCA to anti-double stranded DNA antibodies (dsDNAab. Results. A greater proportion of PLN patients had prediagnostic MPO-ANCA levels above ≥3 U/mL and ≥6 U/mL compared to SLE without LN (91% versus 43%, p<0.001; 57% versus 5%, p<0.001, resp.. In subgroup analysis, the MPO-ANCA threshold of ≥3 U/mL was significant at <1 year (88% versus 39%, p=0.007 and 1–4 years (87% versus 38%, p=0.009 prior to diagnosis. Statistically significant subclinical MPO-ANCA levels (≥3 U/mL occurred prior to statistically significant dsDNAab ≥ 3 IU/ml (89% versus 11%, p=0.003. Conclusions. Subclinical MPO-ANCA levels could distinguish future PLN from SLE without LN. MPO-ANCA manifests prior to clinical disease and subclinical dsDNAab to suggest that it may contribute directly to PLN pathogenicity.

    {sup 67}Ga citrate scan has been requested for detection or follow-up of inflammatory or neoplastic disease. Visualization of {sup 67}Ga citrate in the kidneys at 48 and 72 hr post injection is usually interpreted as evidence of renal pathology. But precise mechanisms of abnormal {sup 67}Ga uptake in kidneys were unknown. We undertook a study to determine the clinical value of {sup 67}Ga citrate imaging of the kidneys in 68 patients with primary or secondary nephropathy confirmed by renal biopsy and 66 control patients without renal disease. Renal uptake in 48 to 72 hr images was graded as follows: Grade 0=background activity;1=faint uptake greater than background; 2=definite uptake, but less than lumbar vertebrae;3 same uptake as lumbar vertebrae, but less than liver; 4=same or higher uptake than liver. The results were as follows. 1) 42 of 68(62%) patients with noninfectious nephritis showed grade 2 or higher {sup 67}Ga renal uptake but only 10 percent of control patients showed similar uptake. 2) In 14 patients with systemic lupus erythematosus, 8 of 9 (89%) patients with lupus nephritis exhibited marked renal uptake. 3) 36 of 41 patients (88%) with combined nephrotic syndrome showed Grade 2 or higher renal uptake. 4) Renal {sup 67}Ga uptake was correlated with clinical severity of nephrotic syndrome determined by serum albumin level, 24 hr urine protein excretion and serum lipid levels. 5) After complete remission of nephrotic syndrome, renal uptake in all 8 patients who were initially Grade 3 or 4, decreased to Grade 1 or 0. In conclusion, we think that the mechanism of renal {sup 67}Ga uptake in nephrotic syndrome might be related to the pathogenesis of nephrotic syndrome. In systemic lupus erythematosus, {sup 67}Ga citrate scan is useful in predicting renal involvement.

    To identify prognostic factors associated with response to induction therapy in lupus nephritis (LN) according to the stage of treatment. We analyzed a retrospective cohort of patients of systemic lupus erythematosus (SLE) with biopsy-proven LN from January 2001 to December 2008. LN was classified according to WHO. All patients received induction therapy and had a minimum follow-up period of two years. We analyzed 18 clinical and laboratory variables that potentially have predictive value for response to therapy. We identified predictors of therapeutic response at 6, 12 and 24 months by univariate and multivariate analysis; odds ratios (OR) with confidence intervals (CI) 95% were also calculated. We reviewed the clinical records of 168 patients, 141 female (84%). The response rate was 69% at 6 months, 86.9% at 12 months and 79.7% at 24 months. Multivariate analysis found that > 25 years of age at diagnosis of LN and the presence of microhematuria were factors associated with good response to induction treatment. At 12 months, baseline creatinine clearance < 30ml/min was associated with a poor response to treatment. Finally at 24 months, delay in treatment was a predictor of poor response to treatment and the presence of a histological proliferative NL and low C3 were associated with good response to treatment. There are treatment-modifiable factors that can alter aberrant immunologic activity of NF. Therefore, intensive early treatment of lupus nephritis is associated with favorable response to two years.

    To assess the long-term outcome of lupus nephritis in children with systemic lupus erythematosus followed up over 12 years at a tertiary care teaching hospital in Eastern India. This is a retrospective observational study of the clinicopathological presentation, management, and outcome in 46 children with lupus nephritis over a period of 12 years at a tertiary teaching hospital in Eastern India. Mortality was compared between different lupus classes and therapy groups with Kaplan-Meier analysis and log-rank test. The incidence of lupus nephritis was 58.97% [95% confidence interval (CI) 48.06%-59.89%] with the mean age at presentation being 10.2±2.43 years (range 5.5-14.5) years. Majority belonged to class IV (30.43%), followed by class II (26.91%), class III (23.91), and class V (8.70%). Outcome analysis of children with lupus nephritis over 12 years revealed that 24 (52.17%) achieved complete remission of disease activity, 5 attained partial remission, 4 continued to have active disease, 5 developed end-stage renal disease (ESRD), and 8 died. Overall mortality thus observed was 17.39% with septicemia in the background of ESRD being the commonest cause. No significant difference in mortality was observed between different lupus nephritis classes or therapy arm groups. The study throws light on various aspects of lupus nephritis and their long-term outcome patterns in children from developing countries such as India.

We believe that the initial glomerular disease could have been due to a parvovirus infection followed by un unexpected acute tubular interstitial nephritis, rapidly progressing to chronic renal disease. This case represents, to our knowledge, the first time that a direct relationship between parvovirus infection and acute tubulointerstitial disease has been demonstrated.

    Lupus nephritis is a common and severe manifestation of systemic lupus erythematosus that disproportionately affects non-Whites and those in lower socioeconomic groups. This review discusses recent data on the incidence, prevalence, and outcomes of patients with lupus nephritis with a focus on low-income US Medicaid patients. We also review recent guidelines on diagnosis, treatment, and screening for new onset and relapses of lupus nephritis. Finally, we discuss the management of lupus nephritis from a rheumatologist’s perspective, including vigilance for the common adverse events related to disease and treatment, and review prevention and new treatment strategies.

    Tattoo reactions can be clinically challenging to diagnose and treat. We present a case of a biopsy-proven granulomatous reaction to purple tattoo ink that clinically mimicked lichen planus. This reaction was successfully treated with one course of intralesional kenalog (ILK), with no recurrence six months after treatment. To our knowledge, this is the first report of a granulomatous tattoo reaction appearing clinically like lichen planus, and one of the few reports of a reaction to purple tattoo pigment. It highlights the importance of biopsying tattoo-related dermatoses prior to treatment in order to confirm the diagnosis. It also illustrates how a minimally invasive technique utilizing ILK to treat a granulomatous tattoo reaction can result in excellent dermatologic, cosmetic, and symptomatic outcomes. Based on this therapeutic success, we believe treatment with ILK injections should be attempted before more invasive modalities such as excision or laser therapy.

    We report a therapeutic response to infliximab in a patient with idiopathic granulomatous hepatitis resistant to treatment with methotrexate and corticosteroids. A 41-year-old woman presented with a 12-month history of fever, night sweat, gross hepatomegaly and 13 kg weight loss. Infection and malignancy were carefully excluded and a liver biopsy showed changes consistent with idiopathic granulomatous hepatitis. The patient was treated with high dose steroids and methotrexate, but her clinical symptoms and biochemical and radiological signs did not settle. Introduction of infliximab led to rapid and sustained resolution of symptoms, hepatomegaly and liver function tests (LFTs) after 1 year of follow-up. To our knowledge this is the first successful use of infliximab in idiopathic granulomatous hepatitis. PMID:21686858

    The most important smoking-related interstitial lung diseases (ILD) are respiratory bronchiolitis, respiratory bronchiolitis-associated interstitial lung disease, desquamative interstitial pneumonia, and Langerhans' cell histiocytosis. Although traditionally considered to be discrete entities, smoking-related ILDs often coexist, thus accounting for the sometimes complex patterns encountered on high-resolution computed tomography (HRCT). Further studies are needed to elucidate the causative role of smoking in the development of pulmonary fibrosis

    Microsporidial stromal keratitis poses several diagnostic challenges. Patients may present with corneal ulceration, marked stromal thinning, or even as a quite corneal scar. The presentation of microsporidial stromal keratitis commonly mimics viral keratitis. Microbiology scrapings are usually helpful; however, scraping and culture-negative cases pose a significant diagnostic dilemma. Histopathological examination is diagnostic but shows varying degree of inflammation, predominantly composed of polymorphonuclear leukocytes. Granulomatous inflammation, in microsporidial stromal keratitis, is never well described, and the authors in this article aim to describe the presence of granulomatous inflammation in microsporidial stromal keratitis, in patients with associated herpes simplex virus (HSV) keratitis. This was a retrospective and observational study conducted at a tertiary eye care center. Of 263 patients who underwent therapeutic penetrating keratoplasty for infectious keratitis, during 2011-2013, seven patients were diagnosed as microsporidial stromal keratitis. Microsporidial spores could be demonstrated on microbiological scrapings in 5/7 (71%) of cases, but identified on histopathological examination and also confirmed on polymerase chain reaction (PCR) for microsporidium in 100% of cases. There was evidence of diffuse stromal necrosis with markedly severe degree of polymorphonuclear leukocytic infiltrates, with granulomatous inflammation in 42% of cases. Interestingly, these were positive for HSV-1 DNA on PCR. Review of medical records revealed much severe clinical presentations in patients with granulomatous inflammation, in comparison to cases without granulomatous inflammation. The authors hereby recommend that severe clinical presentation in patients with microsporidial stromal keratitis, markedly dense polymorphonuclear leukocytic infiltrates or the presence of granulomatous inflammation on the histopathological examination, should be investigated

    Accelerated severe lupus nephritis (ASLN), with an acute onset of severe clinical manifestations and histopathologic renal lesions, may represent transformation of mild LN to a severe form of glomerulonephritis. Abnormal activation of T and B cells and/or oxidative stress may play a major role in the pathogenesis of ASLN. This study tested the hypothesis that antroquinonol, a purified compound and major effective component of Antrodia camphorata with antiinflammatory and antioxidant activities, might prevent the transformation of mild LN into higher-grade (severe) nephritis in a murine lupus model. Experimental ASLN was induced in (NZB×NZW)F1 mice by twice weekly intraperitoneal injections of Salmonella-type lipopolysaccharide (LPS). Starting 2 days after the first dose of LPS, mice were treated daily with antroquinonol, administered by gavage, for different durations up to 5 weeks. Antroquinonol administration significantly ameliorated the proteinuria, hematuria, impairment of renal function, and development of severe renal lesions, especially cellular crescent formation, neutrophil infiltration, fibrinoid necrosis, and T cell proliferation in the glomerulus, as well as periglomerular interstitial inflammation. Mechanistic analyses revealed that antroquinonol 1) inhibited T cell activation/proliferation, but enhanced Treg cell suppression and reduced renal production of interleukin-18 (IL-18); 2) inhibited production of reactive oxygen species and nitric oxide, but increased activation of Nrf2 in the kidney; and 3) suppressed renal inflammation via blocking of NF-κB activation. Antroquinonol may have therapeutic potential for the early treatment of ASLN via its differential regulation of T cell function and lowering of IL-18 production, but also via the promotion of Nrf2 activation.

    Full Text Available Granulomatous reactions have been reported in association with lymphomas, more often with Hodgkins disease than with Non-Hodgkins Lymphoma. Not many reports are available on the association of anaplastic large-cell lymphoma with sarcoid-type granuloma. Herein, we report a case of an elderly female with generalized lymphadenopathy who had a florid granulomatous reaction almost masking the lymphoma cells in the lymph node biopsy. A detailed clinical history, careful histological examination and immunohistochemistry helped in attaining the correct diagnosis.

    Full Text Available Neutrophil dysfunction syndromes can sometimes mimic the clinical and pathological features of inflammatory bowel disease. The case of a 3.5-year-old boy with chronic diarrhea, abdominal pain, poor growth since infancy and microcytic, hypochromic anemia is presented. After an extensive diagnostic evaluation, he was found to have a rare variant (type IVA of chronic granulomatous disease. His gastrointestinal symptoms markedly improved during therapy with gamma-interferon. Chronic granulomatous disease can present initially with a clinical picture suggestive of chronic intestinal inflammation. Therefore it should be considered in the differential diagnosis of atypical inflammatory bowel disease, both in children and young adults.

    Full Text Available A number of recent advances have been made in the epidemiology and treatment of chronic granulomatous disease. Several reports from developing regions describe the presentations and progress of local populations, highlighting complications due to Bacillus Calmette–Guérin vaccination. A number of new reports describe complications of chronic granulomatous disease in adult patients, as more survivors reach adulthood. The complications experienced by X-linked carriers are particularly highlighted in three new reports, confirming that infection and inflammatory or autoimmune conditions are more common and severe than previously recognised. Finally, definitive treatment with haematopoietic stem cell transplantation and gene therapy is reviewed.

    The breast infection by M tuberculosis is rare, when it occurs, clinical and histologically confused with other forms of granulomatous inflammation, making it essential to use other diagnostic methods also may be negative. We report a patient with fimica mastitis that originally was treated as idiopathic granulomatous mastitis with apparent satisfactory clinical response. However, frequent relapses forced to look for other etiologies. Fortunately, the PCR showed the cause and was managed with specific treatment with disappearance of the disease. Clinical suspicion should be in mind when faced with a case like ours.

    The radiologic findings of a single nodule from Pneumocystis jirovecii pneumonia (PJP) have been rarely reported. We described a case of granulomatous PJP manifesting as a solitary pulmonary nodule with a halo sign in a 69-year-old woman with diffuse large B cell lymphoma during chemotherapy. The radiologic appearance of the patient suggested an infectious lesion such as angioinvasive pulmonary aspergillosis or lymphoma involvement of the lung; however, clinical manifestations were not compatible with the diseases. The nodule was confirmed as granulomatous PJP by video-assisted thoracoscopic surgery biopsy.

    Risk of subclinical atherosclerosis is increased in patients with systemic lupus erythematosus (SLE). We correlated carotid intima media thickness (CIMT) and endothelial dysfunction through flow-mediated dilation (FMD) in SLE patients with the SLE Disease Activity Index (SLEDAI). This single-centre cross-sectional study recruited 100 consenting SLE outpatients (ACR 1997 criteria) out of which 50 had nephritis, with disease duration of ≥2 years for SLE and ≥6 months for lupus nephritis. We measured baseline laboratory levels, CIMT and FMD (after brachial BP cuff inflation up to 200 mmHg for five minutes), and calculated SLEDAI. Mean age was 29.88 ± 6.53 years; 95/100 were female. CIMT showed positive correlation (p = 0.037; rho = 0.209), and FMD showed inverse correlation with patient's age (p = 0.011; rho = -0.252). CIMT and FMD were more deranged in patients aged ≥25 years (p nephritis (p > 0.05), whereas SLEDAI and FMD were more deranged in nephritis patients (p nephritis, FMD showed significant inverse correlation with disease duration (p = 0.043; rho = -0.288) and urine albumin (p = 0.045; rho = -0.285). In nephritis patients, the correlation between age of the patient was significantly positive with CIMT (p = 0.001; rho = 0.441) and significantly inverse with FMD (p = 0.028; rho = -0.312). SLE patients with nephritis are at a higher risk to develop arterial stiffening, leading to early end-organ damage. Early aggressive treatment may prevent endothelial dysfunction. FMD using vascular ultrasonography on the brachial artery represents a non-invasive, repeatable and useful method for the assessment of endothelial dysfunction. © The Author(s) 2015.

    In the present study, we sought to evaluate the complement activation product C4d as a marker for lupus nephritis in systemic lupus erythematosus (SLE). C4d levels were determined by enzyme-linked immunosorbent assay in plasma samples of patients with established SLE using a novel approach based on detection of a short linear cleavage neoepitope. Cross-sectional associations were studied in 98 patients with SLE with samples taken at lower or higher respective disease activity. Temporal associations were investigated in 69 patients with SLE who were followed longitudinally for up to 5 years. Plasma samples from 77 healthy donors were included as controls. C4d levels were negligible in healthy control subjects and significantly increased in patients with SLE in the cross-sectional study (p Lupus Erythematosus Disease Activity Index (p = 0.011) and predominantly with lupus nephritis (p = 0.003), exhibiting a sensitivity of 79% to identify patients with nephritis. High C4d levels together with the presence of anti-dsDNA autoantibodies preceded and thus predicted future lupus nephritis in the longitudinal study (OR 5.4, 95% CI 1.4-21.3). When we considered only patients with renal involvement (19 of 69) during the longitudinal study, we found that high C4d levels alone could forecast recurrence of future lupus nephritis (OR 3.3, 95% CI 1.2-9.6). C4d appears to be a valuable marker for use in monitoring of patients with SLE, particularly for lupus nephritis. Importantly, C4d levels can predict impending flares of lupus nephritis and may thus be useful for informing treatment.

  7. Renal Dnase1 enzyme activity and protein expression is selectively shut down in murine and human membranoproliferative lupus nephritis.

    Directory of Open Access Journals (Sweden)

    Svetlana N Zykova

    Full Text Available BACKGROUND: Deposition of chromatin-IgG complexes within glomerular membranes is a key event in the pathogenesis of lupus nephritis. We recently reported an acquired loss of renal Dnase1 expression linked to transformation from mild to severe membranoproliferative lupus nephritis in (NZBxNZWF1 mice. As this may represent a basic mechanism in the progression of lupus nephritis, several aspects of Dnase1 expression in lupus nephritis were analyzed. METHODOLOGY/PRINCIPAL FINDINGS: Total nuclease activity and Dnase1 expression and activity was evaluated using in situ and in vitro analyses of kidneys and sera from (NZBxNZWF1 mice of different ages, and from age-matched healthy controls. Immunofluorescence staining for Dnase1 was performed on kidney biopsies from (NZBxNZWF1 mice as well as from human SLE patients and controls. Reduced serum Dnase1 activity was observed in both mesangial and end-stage lupus nephritis. A selective reduction in renal Dnase1 activity was seen in mice with massive deposition of chromatin-containing immune complexes in glomerular capillary walls. Mice with mild mesangial nephritis showed normal renal Dnase1 activity. Similar differences were seen when comparing human kidneys with severe and mild lupus nephritis. Dnase1 was diffusely expressed within the kidney in normal and mildly affected kidneys, whereas upon progression towards end-stage renal disease, Dnase1 was down-regulated in all renal compartments. This demonstrates that the changes associated with development of severe nephritis in the murine model are also relevant to human lupus nephritis. CONCLUSIONS/SIGNIFICANCE: Reduction in renal Dnase1 expression and activity is limited to mice and SLE patients with signs of membranoproliferative nephritis, and may be a critical event in the development of severe forms of lupus nephritis. Reduced Dnase1 activity reflects loss in the expression of the protein and not inhibition of enzyme activity.

    Podocalyxin is an electronegative sialoglycoprotein that prevents the podocyte foot process from collapsing. The aim of this study was to detect an association between the glomerular immunohistochemical (IHC) expression of podocalyxin and the degree of podocyte effacement detected by electron microscopy, and to evaluate the role of podocalyxin IHC expression as a novel marker for disease activity in lupus nephritis (LN). Thirty-two renal biopsies of active lupus nephritis patients were studied. Clinical assessment by the systemic lupus activity measure (SLAM-R) score and laboratory data were included [serum creatinine, 24-h urinary protein, antinuclear antibodies (ANA), anti-double-strand DNA antibodies (anti-dsDNA), C3 and C4]. Light (L/M) and electron microscopic (E/M) examination was conducted. Podocyte loss was evaluated by immunohistochemistry with monoclonal anti-podocalyxin antibodies by means of a semiquantitative score that was graded from 0 to 4+ according to the percentage of glomerular involvement. 22 cases (68.8%) with LN class IV, 6 (18.8%) with class III and 4 (12.5%) with class V. The mean age was (25.41±10.13) years. There was a significant negative correlation between IHC podocalyxin score and LN class, and NIH activity parameters such as leukocyte infiltration, endocapillary proliferation, fibrinoid necrosis and cellular crescent and disease activity index but not chronicity index. There was a highly significant negative correlation between IHC podocalyxin and podocyte effacement by E/M (rs=-0.903, P=0.000), and E/M immune deposits (r=-0.53, P=0.001), and a significant association with degree of proteinuria, ANA and SLAM score (P<0.05). Podocyte loss indicated by podocalyxin immunohistochemical expression reflects the degree of activity and severity of LN and the degree of podocyte effacement by E/M.

    Interstitial cystitis (IC)/bladder pain syndrome (BPS) is a debilitating disease characterized with urgency, frequency, and pelvic pain affecting especially women. Sexual dysfunction in female patients with IC/BPS consists of dyspareunia, altered sexual desire and orgasm frequency and insufficient lubrication is reported to negatively affect the patient's quality of life. In the present study, we aimed to determine the association between IC/BPS and sexual dysfunction and improvement in sexual dysfunction related to given treatments. A PubMed/Medline and EMBASE search was conducted using keywords: "interstitial cystitis", "sexual dysfunction", and "bladder pain syndrome". Several studies have been conducted to determine the relation between IC/BPS and sexual dysfunction. And also limited studies focusing on IC/BPS specific treatments reported significant improvements in sexual function after either oral or intravesical treatment. However, given the used different questionnaires, study protocols, patient characteristics, previous treatments and follow-up period, it is not possible to make a head-to-head comparison of the treatment effects on sexual function. Further, randomized controlled studies are needed to confirm these results and make a comparison between effects of various treatment modalities on sexual functioning in IC/BPS.

    Full Text Available Research objective: to study the clinical and biochemical risk factors and markers for the formation of tubulointerstitial nephritis  in children with oxalate-calcium crystalluria. Methods: 30 children with tubulointerstitial nephritis were examined on a background  of oxalate-calcium crystalluria. Special clinical and laboratory methods of research were used: stable metabolites of nitric oxide-nitrites and activity of superoxide dismutase, albumin in urine were determined in erythrocytes and urine. To determine the clinical  features of the course and identify risk factors for the development of tubulointerstitial nephritis, we analyzed: perinatal and genealogical anamnesis, the age of debut of oxalate-calcium crystalluria and tubulointerstitial nephritis, and ultrasound data from the organs  of the urinary system. Results: In children with tubulointerstitial nephritis, in 22% of cases the signs of oxalate-calcium crystal-luria preceded the underlying disease. For tubulointerstitial nephritis, which occurred against the background of metabolic disturbances, whose debut occurred at an early age, a latent course is typical, and minimal tubular kidney dysfunction, formed at the age  of 4–11 years. The following clinical and anamnestic factors had the greatest impact on the formation of tubulointerstitial nephritis  from a single-factor analysis: a family history with family history and the presence of 2 degrees of kinship of urolithiasis, a threat of termination of pregnancy and gestosis of the first half of pregnancy, hyperechoic inclusions in the renal parenchyma by ultrasound examination of child. In parallel with the processes of antioxidant protection against the background of oxidative stress, there is an increase in the level of metabolites of nitric oxide in the urine, and in combination with albuminuria, an increase in endothelial dysfunction. Conclusion: the leading factors in the formation of tubulointerstitial nephritis in

    Interstitial ectopic pregnancy is a rare type of tubal pregnancy that poses diagnostic challenge. It is associated with the highest risk of massive, uncontrollable bleeding and can result in uterine rupture in the second trimester. This is a rare case of unruptured interstitial ectopic diagnosed in the first trimester by ultrasonography and managed medically with systemic methrotrexate and serial ultrasound monitoring.`.

    To determine the incidence and reasons for misdiagnosis in interstitial ectopic pregnancy. We conducted a retrospective study from 1990 to 2001. Women with interstitial pregnancy were identified and their case records retrieved and reviewed. Reasons for delay in diagnosis and associated morbidity were recorded. Thirty-six women were diagnosed as having interstitial pregnancy during the study period. Initial diagnosis was incorrect in 15 cases (41.7%). In 14 cases, the interstitial pregnancies were mistaken as intrauterine pregnancy. These misdiagnoses resulted in six inappropriate surgical procedures (evacuation of uterus) being performed and led to rupture of interstitial pregnancy in eight women. In two women, the interstitial pregnancy was mistaken as normal intrauterine pregnancy while the uterus itself was thought to be a cervical fibroid. In both cases, the interstitial pregnancies ruptured at 18-20 weeks of gestation. Despite advances in sonographic skills and equipment and the availability of beta-human chorionic gonadotropin (hCG) monitoring, misdiagnosis of interstitial pregnancy still occurs frequently. Clinicians should be aware of the limitations of various investigations and maintain a high index of suspicion.

    A computer model is developed to simulate the behavior of self-interstitials with particular attention to clustering. Owing to the layer structure of graphite, atomistic simulations can be performed using a large parallelepipedic supercell containing a few layers. In particular, interstitial clustering is studied here using a supercell that contains two basal planes only. Frenkel pairs are randomly produced. Interstitials are placed at sites between the crystal planes while vacancies are distributed in the two crystal planes. The size of the computational cell is 20000 atoms and periodic boundary conditions are used in two dimensions. Vacancies are assumed immobile whereas interstitials are given a certain mobility. Two point defect sinks are considered, direct recombination of Frenkel pairs and interstitial clusters. The clusters are assumed to be mobile up to a certain size where they are presumed to become loop nuclei. Clusters can shrink by emission of singly bonded interstitials or by recombination of a peripheral interstitial with a neighboring vacancy. The conditions under which interstitial clustering occurs are reported. It is shown that when clustering occurs the cluster size population gradually shifts towards the largest size cluster. The implications of the present results for irradiation growth and irradiation-induced amorphization are discussed

    Full Text Available Introduction: Nephritis is the most common of all serious manifestations of SLE. The proliferative forms require immunosuppressive treatment, but responses are not consistent and exacerbations are frequent during or after the treatment has been completed. Methods: We retrospectively analyzed the evolution of a cohort of 84 patients with proliferative lupus nephritis with immunosuppressive treatment, in a long-term (up to 203 months follow up. Were taken as basal: sex, age, latency between onset and diagnosis of SLE nephritis, serum complement, plasmatic creatinine and proteinuria. We evaluated: initial response to therapy, occurrence of relapse or recurrence and score at the end of the observation period. Results: Remission of initial nephritis was seen in 73% of the cases, although at the end of monitoring only 54% of patients were in remission. 45 patients had one episode of nephritis, 32 patients had two, and 7 patients had three. Most of the remissions took place during the maintenance period. Complete remission had better evolution than partial remission. High serum creatinine levels and proteinuria at baseline were indicators of bad prognosis. Oral Azathioprine was more effective than quarterly IV Cylophosphamide as maintenance therapy, despite of a high incidence of relapses. Mycophenolate was not more effective than Cyclophosphamide/azathioprine for the treatment of relapses or recurrences. Conclusions: Our results are similar to the literature. Extended follow up enables the evaluation of the long term result of the initial symptoms, any possible future outbreaks, the effectiveness of the treatment and its evolution after its interruption.

    We aimed to investigate the differences in renal histopathological changes and laboratory parameters between adult and pediatric patients with Henoch-Schönlein purpura nephritis (HSPN), and to analyze the correlation between laboratory parameters and renal histopathological grading. A total of 139 patients diagnosed with HSPN between September 2010 and December 2014 at the First Hospital of Jilin University, China, were retrospectively reviewed. The clinical and pathological characteristics were examined and compared between the adult and the pediatric patients. A majority of adult (75.0%) and pediatric (66.2%) patients were categorized as pathological grade III HSPN. Adults having crescent lesions, interstitial fibrosis and renal artery involvement significantly outnumbered child counterparts (all P<0.05). Pathological grading showed a positive correlation with 24-h urine protein (r=0.307, P=0.009), microalbuminuria (r=0.266, P=0.000) and serum globulin (r=0.307, P=0.014), and a negative correlation with serum albumin (r=0.249, P=0.037) in pediatric patients with HSPN. Among adult patients with HSPN, histopathological grading showed a positive correlation with 24-h urine protein (r=0.294, P=0.015), microalbuminuria (r=0.352, P=0.006), α1-microglobulin (r=0.311, P=0.019) and immunoglobulin G (r=0.301, P=0.023) in urine, and serum creatinine (r=0.292, P=0.018). Further, a negative correlation between serum albumin and pathological grading was also observed (r=0.291, P=0.018). In conclusion, the severity of renal pathological lesions in HSPN patients is well reflected by the levels of proteinuria. Adult patients have more severe renal histopathological changes than pediatric patients.

    Full Text Available Posterior reversible encephalopathy syndrome (PRES is characterized by acute onset of headache, nausea, focal neurological deficits or seizures along with radiological findings of white matter defects in the parietal and occipital lobes. Causes of PRES include uremia, hypertensive encephalopathy, eclampsia and immunosuppressive medications. Usually, the treat-ment of choice involves correcting the underlying abnormality. We describe an unusual case of recurrent PRES caused by uremia during a lupus flare in a patient with biopsy-proven Class IV Lupus Nephritis (LN with vasculitis. PRES in systemic lupus erythematosis (SLE is a rare clin-ical phenomenon and, when reported, it is associated with hypertensive encephalopathy. Our patient did not have hypertensive crisis, but had uremic encephalopathy. The patient′s PRES-related symptoms resolved after initiation of hemodialysis. The temporal correlation of the correc-tion of the uremia and the resolution of the symptoms of PRES show the etiology to be uremic encephalopathy, making this the first reported case of uremia-induced PRES in Class IV LN with vasculitis.

  19. MicroRNAs Implicated in the Immunopathogenesis of Lupus Nephritis

    Full Text Available Systemic lupus erythematosus (SLE is an autoimmune disease characterized by the deposition of immune complexes due to widespread loss of immune tolerance to nuclear self-antigens. Deposition in the renal glomeruli results in the development of lupus nephritis (LN, the leading cause of morbidity and mortality in SLE. In addition to the well-recognized genetic susceptibility to SLE, disease pathogenesis is influenced by epigenetic regulators such as microRNAs (miRNAs. miRNAs are small, noncoding RNAs that bind to the 3′ untranslated region of target mRNAs resulting in posttranscriptional gene modulation. miRNAs play an important and dynamic role in the activation of innate immune cells and are critical in regulating the adaptive immune response. Immune stimulation and the resulting cytokine milieu alter miRNA expression while miRNAs themselves modify cellular responses to stimulation. Here we examine dysregulated miRNAs implicated in LN pathogenesis from human SLE patients and murine lupus models. The effects of LN-associated miRNAs in the kidney, peripheral blood mononuclear cells, macrophages, mesangial cells, dendritic cells, and splenocytes are discussed. As the role of miRNAs in immunopathogenesis becomes delineated, it is likely that specific miRNAs may serve as targets for therapeutic intervention in the treatment of LN and other pathologies.

    Full Text Available Dysfunction of the B lymphocyte, an important component of adaptive immunity, is thought to be important in the pathogenesis of lupus nephritis (LN. There are several novel strategies emerging including B-cell depletion by the monoclonal antibodies to B-cell markers, rituximab. We describe an unusual clinical response of a 22-year-old Hispanic woman with class IV LN with vasculitis while on dialysis to cyclophosphamide (CY and adjunct rituximab. The patient had a history of class III/V LN and was treated with nine months of CY and maintenance therapy with mycophenolate mofetil (MMF for three years. While on MMF, the patient deve-loped class IV LN with vasculitis leading to end-stage renal disease (ESRD. While the patient was on peritoneal dialysis, the patient was treated with two doses of rituximab and six doses of intravenous CY. The patient responded to this regimen and recovered kidney function within four months. The kidney function remained stable nine months after discontinuing peritoneal dialysis.

    Full Text Available Renal involvement determines the prognosis of systemic lupus erythematosus (SLE. The aims of this study were to assess the clinical, laboratory and therapeutic aspects of lupus nephritis (LN in Senegal in order to improve its management. We included all patients presenting with SLE followed-up in the Internal Medicine and Dermatology Clinics of the Aristide Le Dantec University Teaching Hospital of Dakar, from January 1993 to December 2002. Patients with SLE without evidence of LN (defined by proteinuria more than 0.5 g/24 hours and/or hematuria were excluded. A total of 74 patients with a diagnosis of SLE were studied, 42 of whom (56.75% had features of LN. Their mean age was 29.6 years and male-female ratio was 0.13. The nephrotic syndrome was seen in 45.23% of the cases and renal insufficiency in 37.71%. Renal biopsy was performed in 52.38% of the cases, which showed predominantly WHO classes IV and V lesions. The main treatment modality employed was corticoste-roids, while immunosuppressive drugs in addition were used in 35.71% of the patients. The short-term prognosis was favorable but in the middle-term, many patients were lost to follow-up. We conclude that early diagnosis by systematic urine screening, good patient information, percutaneous renal biopsy and use of appropriate immunosuppressive therapy will help improving the prognosis of LN in Senegal.

  2. Outcome of the acute glomerular injury in proliferative lupus nephritis

    Treatment with total lymphoid irradiation (TLI) and corticosteroids markedly reduced activity of systemic lupus erythematosis in 10 patients with diffuse proliferative lupus nephritis (DPLN) complicated by a nephrotic syndrome. Physiologic and morphometric techniques were used serially before, and 12 and 36 mo post-TLI to characterize the course of glomerular injury. Judged by a progressive reduction in the density of glomerular cells and immune deposits, glomerular inflammation subsided. A sustained reduction in the fractional clearance of albumin, IgG and uncharged dextrans of radius greater than 50 A, pointed to a parallel improvement in glomerular barrier size-selectivity. Corresponding changes in GFR were modest, however. A trend towards higher GFR at 12 mo was associated with a marked increase in the fraction of glomerular tuft area occupied by patent capillary loops as inflammatory changes receded. A late trend toward declining GFR beyond 12 mo was associated with progressive glomerulosclerosis, which affected 57% of all glomeruli globally by 36 mo post-TLI. Judged by a parallel increase in volume by 59%, remaining, patent glomeruli had undergone a process of adaptive enlargement. We propose that an increasing fraction of glomeruli continues to undergo progressive sclerosis after DPLN has become quiescent, and that the prevailing GFR depends on the extent to which hypertrophied remnant glomeruli can compensate for the ensuing loss of filtration surface area.

  3. Pauci-Immune Lupus Nephritis: A Case Report

    2008-10-01

    Full Text Available A 26-year-old female with systemic lupus erythematosus was admitted because of dyspnea and progressive lower extremity edema. Laboratory testing showed blood urea nitrogen levels of 147 mg/dL, creatinine of 6.7 mg/dL, serum albumin of 1.7 g/dL and the daily protein loss was 12.7 g. Her C3 level was 60.4 mg/dL and C4 level was 10.2 mg/dL. The antinuclear antibody titer was 1:320, with a homogeneous pattern, but she was negative for anti-dsDNA. ELISA testing for anti-PR3 antibodies and anti-MPO antibodies were all negative. She was also negative for circulating lupus anticoagulant. Renal biopsy revealed diffuse proliferation of glomerular cells, but immunofluorescent microscopy showed no immune deposits and electron microscopy revealed only scanty electron-dense deposits. She received 1 g/day of methylprednisolone intravenously for 3 days, followed by 60 mg/day of prednisolone. She was discharged with serum creatinine decreased to 4.7mg/dL, and a great improvement in dyspnea. Diffuse proliferative lupus nephritis that contains little or no subendothelial deposits is rare. The differential diagnosis, possible mechanisms and treatment are discussed.

    2016-01-01

    Lupus nephritis (LN) is a common and severe complication in patients with lupus. Current therapy is based on immunosuppressive drugs and glucocorticoids. Recently, rituximab has been proposed as an alternative treatment for LN. Rituximab is a monoclonal antibody directed against the CD20 antigen receptor on B cells. The aim of this review is to summarize all the available information about rituximab in LN. Eleven studies were found; three of them were observational studies (2 prospective and 1 retrospective) and eight were clinical trials (7 open-label studies and only 1 randomized controlled trial [RCT]). The evidence is insufficient to establish the role of rituximab in the treatment of LN. Results from the only RCT, which were negative, suggest a clinical benefit in black people. Further studies must confirm this hypothesis. Controlled clinical trials involving adaptive randomization are required to establish the real benefit of rituximab in LN.

    Full Text Available Background: Vitamin D supplementation precipitating hypercalcemic crisis is often the first manifestation in patients with granulomatous disorders. Methods: We report our experience on patients presenting with hypercalcemic crisis due to granulomatous disorder and the role of Vitamin D supplementation in the precipitation of hypercalcemic crisis in them. Results: The study included five patients with granulomatous disorders who presented with hypercalcemic crisis. All patients initially presented with nonspecific constitutional symptoms to other health-care centers to receive high-dose Vitamin D supplementation (60,000 U/week or 600,000 U intramuscular single dose. All of these patients presented with hypercalcemic crisis (serum calcium: 16.04 ± 0.3 mg/dl to our centers after a period of 32.8 ± 9.62 days. Three patients were diagnosed to have sarcoidosis, and two were diagnosed to have tuberculosis. All five patients had parathyroid hormone-independent hypercalcemia with elevated serum 1,25-dihydroxy Vitamin D. Serum angiotensin-converting enzyme level was elevated in all the three patients with sarcoidosis. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography was performed in two patients with sarcoidosis which demonstrated diffusely increased tracer uptake in liver. In these two patients, liver biopsy confirmed the diagnosis. Conclusions: High-dose Vitamin D supplementation is most often the underlying cause of hypercalcemic crisis in patients with granulomatous disorders. Hence, high-dose Vitamin D supplementation should be used judiciously.

    2014-01-01

    Full Text Available Interstitial lung disease (ILD is a final common pathway of a broad heterogeneous group of parenchymal lung disorders. It is characterized by progressive fibrosis of the lung leading to restriction and diminished oxygen transfer. Clinically, the presenting symptoms of ILD are non-specific (cough and progressive dyspnea on exertion and are often attributed to other diseases, thus delaying diagnosis and timely therapy. Clues from the medical history along with the clinical context and radiologic findings provide the initial basis for prioritizing diagnostic possibilities for a patient with ILD. An accurate prognosis and optimal treatment strategy for patients with ILDs can only be after an accurate diagnosis. This review will assist pulmonary physicians and medicine specialist in recognition of ILD. Extensive literature search has been made through PubMed and also Book References has been used for writing this review.

    Full Text Available Henoch-Schonlein purpura (HSP is the most common childhood vasculitis. Renal involvement in HSP is one of the major causes of chronic renal failure in children. It is important to start effective and relatively safe medication to prevent end-stage renal disease (ESRD. Mycophenolate mofetil (MMF appears to be a promising therapeutic agent in many autoimmune diseases such as lupus nephritis and vasculitis. Herein, we describe the treatment with MMF of three patients with HSP nephritis. In two cases with rapidly progressive glomerulonephritis without response to steroid, after treatment with MMF, significant improvement in kidney function and proteinuria were observed. In another patient with HSP nephritic-nephrotic syn-drome who showed resistance to steroid, MMF offered a favorable effect. MMF seems to be a promising therapeutic agent in the treatment of the severe HSP nephritis.

    We encountered an unusual and rare case of 59-year-old woman with Churg-Strauss syndrome (CSS) showing myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA)-related acute renal insufficiency accompanied by eosinophilic tubulointerstitial nephritis. To date, reports in English of CSS presenting with rapidly progressive/acute renal insufficiency and biopsy-proven renal lesions have been uncommon. Here, we discuss this unusual case and review the previously reported CSS cases. The complication of eosinophilic tubulointerstitial nephritis in CSS cases with acute renal insufficiency might be higher than generally thought. Furthermore, the presence of eosinophilic infiltration and eosinophilic tubulointerstitial nephritis might be associated with the good renal outcome in CSS patients.

    The purpose of the stud was to develop a computed tomography (CT) based electromagnetic navigation system for interstitial brachytherapy. This is especially designed for situations when needles have to be positioned adjacent to or within critical anatomical structures. In such instances interactive 3D visualisation of the needle positions is essential. The material consisted of a Polhemus electromagnetic 3D digitizer, a Pentium 200 MHz laptop and a voice recognition for continuous speech. In addition, we developed an external reference system constructed of Perspex which could be positioned above the tumour region and attached to the patient using a non-invasive fixation method. A specially designed needle holder and patient bed were also developed. Measurements were made on a series of phantoms in order to study the efficacy and accuracy of the navigation system. The mean navigation accuracy of positioning the 20.0 cm length metallic needles within the phantoms was in the range 2.0-4.1 mm with a maximum of 5.4 mm. This is an improvement on the accuracy of a CT-guided technique which was in the range 6.1-11.3 mm with a maximum of 19.4 mm. The mean reconstruction accuracy of the implant geometry was 3.2 mm within a non-ferromagnetic environment. We found that although the needles were metallic this did not have a significant influence. We also found for our experimental setups that the CT table and operation table non-ferromagnetic parts had no significant influence on the navigation accuracy. This navigation system will be a very useful clinical tool for interstitial brachytherapy applications, particularly when critical structures have to be avoided. It also should provide a significant improvement on our existing technique

    Immune-mediated nephritis contributes to disease in systemic lupus erythematosus, Goodpasture syndrome (caused by antibodies specific for glomerular basement membrane [anti-GBM antibodies]), and spontaneous lupus nephritis. Inbred mouse strains differ in susceptibility to anti-GBM antibody–induced and spontaneous lupus nephritis. This study sought to clarify the genetic and molecular factors that may be responsible for enhanced immune-mediated renal disease in these models. When the kidneys of 3 mouse strains sensitive to anti-GBM antibody–induced nephritis were compared with those of 2 control strains using microarray analysis, one-fifth of the underexpressed genes belonged to the kallikrein gene family, which encodes serine esterases. Mouse strains that upregulated renal and urinary kallikreins exhibited less evidence of disease. Antagonizing the kallikrein pathway augmented disease, while agonists dampened the severity of anti-GBM antibody–induced nephritis. In addition, nephritis-sensitive mouse strains had kallikrein haplotypes that were distinct from those of control strains, including several regulatory polymorphisms, some of which were associated with functional consequences. Indeed, increased susceptibility to anti-GBM antibody–induced nephritis and spontaneous lupus nephritis was achieved by breeding mice with a genetic interval harboring the kallikrein genes onto a disease-resistant background. Finally, both human SLE and spontaneous lupus nephritis were found to be associated with kallikrein genes, particularly KLK1 and the KLK3 promoter, when DNA SNPs from independent cohorts of SLE patients and controls were compared. Collectively, these studies suggest that kallikreins are protective disease-associated genes in anti-GBM antibody–induced nephritis and lupus. PMID:19307730

    MicroRNAs (miRNA) have emerged as an important new class of modulators of gene expression. In this study we investigated miRNA that are differentially expressed in lupus nephritis. Microarray technology was used to investigate differentially expressed miRNA in peripheral blood mononuclear cells (PBMCs) and Epstein-Barr Virus (EBV)-transformed cell lines obtained from lupus nephritis affected patients and unaffected controls. TaqMan-based stem-loop real-time polymerase chain reaction was used for validation. Microarray analysis of miRNA expressed in both African American (AA) and European American (EA) derived lupus nephritis samples revealed 29 and 50 differentially expressed miRNA, respectively, of 850 tested. There were 18 miRNA that were differentially expressed in both racial groups. When samples from both racial groups and different specimen types were considered, there were 5 primary miRNA that were differentially expressed. We have identified 5 miRNA; hsa-miR-371-5P, hsa-miR-423-5P, hsa-miR-638, hsa-miR-1224-3P and hsa-miR-663 that were differentially expressed in lupus nephritis across different racial groups and all specimen types tested. Hsa-miR-371-5P, hsa-miR-1224-3P and hsa-miR-423-5P, are reported here for the first time to be associated with lupus nephritis. Our work establishes EBV-transformed B cell lines as a useful model for the discovery of miRNA as biomarkers for SLE. Based on these findings, we postulate that these differentially expressed miRNA may be potential novel biomarkers for SLE as well as help elucidate pathogenic mechanisms of lupus nephritis. The investigation of miRNA profiles in SLE may lead to the discovery and development of novel methods to diagnosis, treat and prevent SLE.

    Respiratory involvement in Crohn's disease (CD) is a rare manifestation known to involve the large and small airways, lung parenchyma, and pleura. The clinical presentation is nonspecific, and diagnostic tests can mimic other pulmonary diseases, posing a diagnostic challenge and delay in treatment. We report a case of a 60-year-old female with a history of CD and psoriatic arthritis who presented with dyspnea, fever, and cough with abnormal radiological findings. Diagnostic testing revealed an elevated CD4:CD8 ratio in the bronchoalveolar lavage fluid, and cryoprobe lung biopsy results showed non-necrotizing granulomatous inflammation. We describe here the second reported case of pulmonary involvement mimicking sarcoidosis in Crohn's disease and a review of the literature on the approaches to making a diagnosis of CD-associated interstitial lung disease.

    Chylothorax is a disease in which chyle leaks and accumulates in the thoracic cavity. Interstitial pneumonia and pneumomediastinum are common thoracic manifestations of dermatomyositis, but chylothorax complicated with dermatomyositis is not reported. We report a case of dermatomyositis with interstitial pneumonia complicated by chylothorax. A 77-year-old woman was diagnosed as dermatomyositis with Gottron's papules, skin ulcers, anti-MDA5 antibody and rapid progressive interstitial pneumonia. Treatment with betamethasone, tacrolimus and intravenous high-dose cyclophosphamide was initiated, and her skin symptoms and interstitial pneumonia improved once. However, right-sided chylothorax began to accumulate and gradually increase, and at the same time, her interstitial pneumonia began to exacerbate, and skin ulcers began to reappear on her fingers and auricles. Although her chylothorax improved by fasting and parenteral nutrition, she died due to further exacerbations of dermatomyositis and interstitial pneumonia in spite of steroid pulse therapy, increase in the betamethasone dosage, additional intravenous high-dose cyclophosphamide and plasma pheresis. An autopsy showed no lesions such as malignant tumors in the thoracic cavity. This is the first report of chylothorax complicated by dermatomyositis with interstitial pneumonia.

    Interstitial pregnancy is a rare and life-threatening condition. Diagnosis and appropriate management are critical in preventing morbidity and death. Four cases of interstitial pregnancy are presented. Diagnostic laparoscopy followed by laparotomy and cornuostomy with removal of products of conception was performed in 1 case. Laparoscopic cornuostomy and removal of products of conception were performed in the subsequent 3 cases with some modifications of the technique. Subsequent successful reproductive outcomes are also presented. Progressively conservative surgical measures are being used to treat interstitial pregnancy successfully, with no negative impact on subsequent pregnancies.

    2015-01-01

    Pleuroparenchymal fibroelastosis (PPFE) is a newly described form of interstitial lung disease that originates in the upper lung zones and typically progresses to involve the entire lung. The disease may be idiopathic but is often associated with other pre- or coexisting conditions. Pneumothorax is a common complication and can occur at presentation or at other times during the course of the disease. Pathologically, interstitial fibrosis takes the form of a dense consolidation with some preservation of alveolar septal outlines and demonstrates a distinctly abrupt interface with residual normal lung. Unrecognized cases of PPFE may be incorrectly diagnosed as sarcoidosis, atypical idiopathic pulmonary fibrosis, or other unclassifiable interstitial pneumonias. PMID:26090119

    HRCT was carried out in twenty patients with diffuse interstitial pneumonia: 13 cases of IIP, 3 of BOOP, 2 of drug-induced pneumonia, 1 of rheumatoid lung and acute interstitial pneumonia of unknown origin. With special attention to inflammatory activity, the patients underwent HRCT periodically during the treatment. Correlative investigation between HRCT image and grade of accumulation in 67 Ga scintigraphy was also performed. Response to steroid therapy was clearly reflected on HRCT image, that was shown as decreasing pulmonary density or thinning of honeycomb wall. HRCT is considered to be useful in assessing the activity of diffuse interstitial pneumonia. (author)

    A 27-year-old woman was referred to our hospital because of pancytopenia and nephritic syndrome in November, 2008. The findings of physical and laboratory examinations showed systemic lupus erythematosus (SLE). Diffuse proliferative lupus nephritis(group IV-G(A))was confirmed by renal biopsy. After combined therapy with prednisolone, intravenous cyclophosphamide pulse and mizoribine, proteinuria decreased from 13.0 g/day to 2.0 g/day and the serum complement level recovered to the normal level. However, she visited our hospital again for management of bleeding tendency in July 2009. She was diagnosed as hemophagocytic syndrome (HPS), with pancytopenia, high ferritin, high LDH level and hemophagocytosis in the bone marrow. She was treated effectively with steroid pulse therapy, but relapsed with HPS after two weeks. Although her child caught a cold, the case did not show any sign or symptom of infection, such as the common cold. However, we diagnosed her HPS as infection-associated hemophagocytic syndrome (IAHS) because she was not in the active phase of SLE at the onset of hemophagocytosis and the laboratory findings showed elevation of her serum ferritin and LDH. Therefore, we considered that her infectious sign may have been concealed by immunosuppressive therapy with prednisolone for SLE. It is very difficult to distinguish between IAHS and autoimmune-associated hemophagocytic syndrome (AAHS)in autoimmune diseases, but the differential diagnosis is necessary to treat the HPS. Here, we report an important case of HPS complicated with SLE. This case may attract interest particularly in the management of HPS-complicated autoimmune disease. Therefore, we report it with a review of the literature.

    Full Text Available To assess clinical characteristics, pathological findings, and therapeutic response in children with lupus nephritis (LN, we retrospectively studied 25 children under 16 years of age with LN at the Abozar children′s hospital from 1995 to 2006. The study included 13(65% girls and 7(35% boys. The mean age at the time of diagnosis of SLE was 10.2 (± 4.8 years. Eighteen patients (90% were more than 8 years old. Sixty percent of the patients presented as nephritic-nephrotic syndrome. All the patients underwent percutaneous renal biopsy and were followed up for at least 36 months. The clinical and serologic parameters at the time of renal biopsy were recorded. Twenty patients were treated with the following regimens: one (class I with low dose prednisone, 7 (class II, III with high-dose of prednisone, 12 (class IV with high-dose prednisone plus 13 intermittent intravenous cyclophosphamide (CTX pulses (monthly for 6 months and then every 3 months, followed by mycophenolate mofetil (MMF as maintenance therapy. Remission was achieved in 17 (85% cases; one required hemodialysis and 2 died due to renal failure and central nervous system involvement. Among 12 cases with class IV, 11 responded to prednisone and intravenous CTX pulses. We conclude that i.v. pulses of CTX induced clinical remission of renal disease in the majority of children with severe LN. MMF maintenance therapy was effective after induction of remission in refractory cases. However, this study was performed in a small number of subjects, further studies to confirm the long-term efficacy and safety of CTX pulse therapy on larger numbers of patients are warranted.

    Full Text Available Lupus nephritis (LN is among the most serious complications of systemic lupus erythematosus (SLE, which causes significant morbidity and mortality. Renalase is a novel, kidney-secreted cytokine-like protein that promotes cell survival. Here, we aimed to investigate the relationship of serum renalase levels with LN and its role in the disease progression of LN.For this cross-sectional study, 67 LN patients and 35 healthy controls were enrolled. Seventeen active LN patients who received standard therapies were followed up for six months. Disease activity was determined by the SLE Disease Activity-2000 (SLEDAI-2K scoring system and serum renalase amounts were determined by ELISA. Predictive value of renalase for disease activity was assessed. Furthermore, the expression of renalase in the kidneys of patients and macrophage infiltration was assessed by immunohistochemistry.Serum renalase amounts were significantly higher in LN patients than in healthy controls. Moreover, patients with proliferative LN had more elevated serum renalase levels than Class V LN patients. In proliferative LN patients, serum renalase levels were significantly higher in patients with active LN than those with inactive LN. Serum renalase levels were positively correlated with SLEDAI-2K, 24-h urine protein excretion, ds-DNA and ESR but inversely correlated with serum albumin and C3. Renalase amounts decreased significantly after six-months of standard therapy. The performance of renalase as a marker for diagnosis of active LN was 0.906 with a cutoff value of 66.67 μg/ml. We also observed that the amount of renalase was significantly higher in glomerular of proliferative LN along with the co-expression of macrophages.Serum renalase levels were correlated with disease activity in LN. Serum renalase might serve as a potential indicator for disease activity in LN. The marked increase of glomerular renalase and its association with macrophages suggest that it might play an

    2002-01-01

    Interstitial cystitis is an increasingly common disease characterized by urgency, frequency, and pelvic pain. Its etiology is poorly understood but is likely to be multifactorial. A proposed pathophysiology describing a cascade of events, including epithelial dysfunction, mast cell activation, and neurogenic inflammation, is presented. Using this model, multimodality therapy regimens have been developed that treat all components of this cascade. Multimodality therapy appears more effective than single agents in the treatment of interstitial cystitis. PMID:16986029

    2015-06-01

    Full Text Available Systemic lupus erythematosus (SLE is an autoimmune disease that can affect multiple different organs, including the kidneys and central nervous system (CNS. Conventional radiological examinations in SLE patients include volumetric/ anatomical computed tomography (CT, magnetic resonance imaging (MRI and ultrasound (US. The utility of these modalities is limited, however, due to the complexity of the disease. Furthermore, CT and MRI contrast agents are contraindicated in patients with renal impairment. Various radiologic methods are currently being developed to improve disease characterization in patients with SLE beyond simple anatomical endpoints. Physiological non-contrast MRI protocols have been developed to assess tissue oxygenation, glomerular filtration, renal perfusion, interstitial diffusion, and inflammation-driven fibrosis in lupus nephritis (LN patients. For neurological symptoms, vessel size imaging (VSI, an MRI approach utilizing T2-relaxing iron oxide nanoparticles has shown promise as a diagnostic tool. Molecular imaging probes (mostly for MRI and nuclear medicine imaging have also been developed for diagnosing SLE with high sensitivity, and for monitoring disease activity. This paper reviews the challenges in evaluating disease activity in patients with LN and neuropsychiatric systemic lupus erythematosus (NPSLE. We describe novel MRI and positron-emission tomography (PET molecular imaging protocols using targeted iron oxide nanoparticles and radioactive ligands, respectively, for detection of SLE-associated inflammation.

    Full Text Available Abstract Interstitial lung disease (ILD in infants and children comprises a large spectrum of rare respiratory disorders that are mostly chronic and associated with high morbidity and mortality. These disorders are characterized by inflammatory and fibrotic changes that affect alveolar walls. Typical features of ILD include dyspnea, diffuse infiltrates on chest radiographs, and abnormal pulmonary function tests with restrictive ventilatory defect and/or impaired gas exchange. Many pathological situations can impair gas exchange and, therefore, may contribute to progressive lung damage and ILD. Consequently, diagnosis approach needs to be structured with a clinical evaluation requiring a careful history paying attention to exposures and systemic diseases. Several classifications for ILD have been proposed but none is entirely satisfactory especially in children. The present article reviews current concepts of pathophysiological mechanisms, etiology and diagnostic approaches, as well as therapeutic strategies. The following diagnostic grouping is used to discuss the various causes of pediatric ILD: 1 exposure-related ILD; 2 systemic disease-associated ILD; 3 alveolar structure disorder-associated ILD; and 4 ILD specific to infancy. Therapeutic options include mainly anti-inflammatory, immunosuppressive, and/or anti-fibrotic drugs. The outcome is highly variable with a mortality rate around 15%. An overall favorable response to corticosteroid therapy is observed in around 50% of cases, often associated with sequelae such as limited exercise tolerance or the need for long-term oxygen therapy.

    1984-01-01

    Dermatophilus congolensis was inoculated subcutaneously into 6 ewes and the resulting lesions were examined by light and electron microscopy. The organism was recovered from the subcutaneous lesions. The lesions were suppurative in the early stages and granulomatous in the advanced stage, but abscesses were the usual lesion observed. The granulomas were composed of several layers; central bacterial colony, neutrophil layer, layer of macrophages, epithelioid cells and Langhans and foreign body type giant cells with a periphery of connective tissue. Multiloculated granulomas were observed. Electron microscopic examination confirmed the cell types of the lesions. Epithelioid and giant cells were characterized by the shape and number of the nuclei and complex and abundant organelles. Interdigitations of the blunt pseudopodia of adjacent cells were also found. It is concluded that the organism can produce both granulomatous lesions and abscesses which differ from those of orthodox dermatophilosis but are similar to those described in "atypical dermatophilosis".

    2006-11-01

    A case of eosinophilic granulomatous gastroenterocolitis and hepatitis in a 1-year-old male Siberian Husky is described. The dog presented with a history of diarrhea, weakness, lethargy, and anorexia of several months' duration. Hematologic and biochemical examinations, abdominal ultrasonography, computer tomography, and exploratory laparotomy were performed. Histopathologic examination of full-thickness biopsies from the gastrointestinal tract and liver revealed the presence of eosinophilic granulomatous lesions in the submucosa and tunica muscularis of stomach, jejunum, ileum, colon, and liver. Infectious agents were not detected by light microscopic and electron microscopic examination or by immunohistochemistry. On the basis of the findings, it is concluded that the disease in this dog represents an unusual manifestation of chronic idiopathic inflammatory bowel disease.

    2003-08-01

    Dentogenous inflammatory diseases can lead to typical dermatological facial symptoms with formation of cutaneous sinuses. Partsch's chronic granulomatous inflammation can result from conducted inflammation of a nonvital tooth via a chronic apical inflammation. In this rare disease, the granulomatous tissue perforates the bone, channels through the overlying skin, and drains via cutaneous or oral sinuses. A frequent localization of the cutaneous sinus is the skin inferior to the body of the mandible, and it is caused by an inflammation of the lower molars. Treatment consists of identifying the responsible teeth and eliminating the focus of infection. Chronically progressive periradicular granuloma and/or radicular cysts can be present with impressive dermatological symptoms. Therefore, X-ray examinations are necessary to exclude possible dentogenic causes in cases of badly healing processes of the face or neck.

    Elevated urine Mg excretion and its correlation with histological damage in tubulo-interstitial nephropathy (TIN) were reported. Here we investigated the clinical significance of the fractional excretion of Mg (FEMg) for the prediction of TIN. We enrolled and assessed 94 adult patients with various renal diseases diagnosed principally by renal biopsy. Our stratified analysis based on the value of the conventional TIN parameter N-acetylglucosaminidase (NAG) excretion showed that the high-NAG index group (more than median value of NAG-to-Cr ratio, n = 47) demonstrated significantly high FEMg values (p = 0.017). A univariate analysis revealed a significant correlation between the FEMg and the NAG index (R = 0.60) but not for other parameters. A multivariate regression analysis confirmed the significance of the FEMg as an effective predictor of the NAG index. The FEMg showed a significant correlation with the estimated glomerular filtration rate (eGFR) in the patients with eGFR ≤ 30 mL/min. The correlation of FEMg with the NAG index was not observed in the primary glomerulonephritis patients but was apparent in the patients with hypertensive nephrosclerosis or interstitial nephritis. Our findings may indicate that the combination of the FEMg and the NAG index can provide a specific, sensitive assessment for TIN in patients without renal insufficiency.

    To observe the therapeutic effect of total glucosides of paeony (TGP) on lupus nephritis (LN) in MRL/lpr mice. MRL/lpr mice with lupus nephritis were randomized into model group and TGP group. The urinary protein content was detected using Coomassie brilliant blue, and the serum levels of IgG anti-double-stranded DNA (dsDNA) antibodies and antinuclear antibodies (ANA) were measured by enzyme-linked immunosorbent assay (ELISA). The changes in the renal pathology were examined microscopically, and the spleen and thymus were weighed to calculate the spleen and thymus indexes. At 15 and 30 days after TGP administration, the urinary protein content in the TGP group was significantly lower than that in the model group (PTGP treatment significantly lowered the serum levels of anti-dsDNA antibodies and ANA and the weight and index of spleen (PTGP treatment, the urinary protein content and the levels of anti-dsDNA antibodies and ANA decreased significantly at 15 and 30 days after TGP administration (PTGP administration, the urinary protein content was significantly lowered in the TGP group as compared to that at 15 days (PTGP can reduce urinary protein content and serum levels of anti-dsDNA antibodies and ANA, and lessen renal pathology in MRL/lpr mice with lupus nephritis, suggesting its therapeutic effect on lupus nephritis.

The patient presented herself during a large outbreak of dengue fever in December 2012 in Maharashtra, India. The diagnosis of dengue fever was confirmed by the presence of NS-1 antigen during the first few days of febrile illness. Eight weeks later, kidney tissue biopsy studies revealed evidence of lupus nephritis on microscopic examination and immunofluorescence. The report interpreted it as focal proliferative glomerulonephritis and segmental sclerosis (Stage IIIC. The case was also found positive for perinuclear antineutrophil cytoplasmic antibodies by indirect immunofluorescence assay. An active and effective management of a case essentially calls for clear perception of differentiating dengue-induced lupus flare, antineutrophil cytoplasmic antibody-related nephropathy, and/or dengue-induced de-novo lupus disease. Dengue viremia may be the trigger for immune complex formation in patients who are predisposed to developing autoimmune diseases. The present case explains the importance of considering the diagnosis of dengue-related lupus nephritis as an atypical occurrence in appropriate situations, as in this case. It would not be improper to regard this escalating disease as an expanded feature of dengue.

    This study investigated the illness perceptions of patients with systemic lupus erythematosus (SLE) and whether perceptions are influenced by type of treatment for proliferative lupus nephritis. In addition, the illness perceptions of SLE patients were compared with those of patients with other chronic illnesses. Thirty-two patients who had experienced at least one episode of proliferative lupus nephritis were included. Patients were treated with either a high or low-dose cyclophosphamide (CYC) regimen (National Institutes of Health [NIH] vs. Euro-Lupus protocol). Illness perceptions were measured with the Brief Illness Perception Questionnaire (B-IPQ) and a drawing assignment. The low-dose CYC group perceived their treatment as more helpful than the high-dose CYC group. In comparison with patients with asthma, SLE patients showed more negative illness perceptions on five of the eight illness perception domains. Drawings of the kidney provided additional information about perceptions of treatment effectiveness, kidney function and patients' understanding of their illness. Drawing characteristics showed associations with perceptions of consequences, identity, concern and personal control. These findings suggest that the type of treatment SLE patients with proliferative lupus nephritis receive may influence perceptions of treatment effectiveness. In addition, patients' drawings reveal perceptions of damage caused by lupus nephritis to the kidneys and the extent of relief provided by treatment. The finding that SLE is experienced as a more severe illness than other chronic illnesses supports the need to more frequently assess and aim to improve psychological functioning in SLE patients.

    We conducted a clinical study in China on the efficacy and safety of mizoribine (MZR) in lupus nephritis. Eleven subjects with proteinuria (≥2 g/day) who had undergone renal biopsy confirming a diagnosis of lupus nephritis (class III: 1 subject; class IV: 6 subjects; class V: 4 subjects) were enrolled. Nine of the subjects were treatment- naive patients who received remission induction therapy, and the other two were switched from cyclophosphamide (CTX) or mycophenolate mofetil due to lack of efficacy. MZR 150 mg was administered once a day. After 6 months, the remission rate was 72.7% (2 subjects achieved complete remission, and 9 partial remission). After 3 and 6 months, significant reductions (p proteinuria (g/day). In the subjects switched to MZR due to lack of efficacy with CTX, the dose was increased from MZR 150-200 mg due to inadequate improvement in proteinuria, and this dose escalation resulted in complete remission after 6 months. It is believed that this kind of dose escalation is one possible treatment option for lupus nephritis. In this study, no adverse events occurred in any of the subjects. We therefore concluded that this first use in China as remission induction therapy in lupus nephritis patients of MZR, which is recognized as an effective maintenance therapy in Japan, was effective. The results also suggest that MZR could be effective in patients for whom other drugs have been insufficiently effective.

  6. Granulomatous slack skin - seven years follow-up of a case with features of "parapsoriasis en plaques", muscle involvement, granulomatous vasculitis, and necrobiotic changes.

    Granulomatous slack skin (GSS) represents an extremely rare variant of mycosis fungoides with only 70 cases reported in the literature to date. It is characterized clinically by the occurrence of bulky, pendulous skinfolds, usually located in flexural areas and histologically by an infiltrate composed of small neoplastic T-lymphocytes joined by granulomatous inflammation with scattered multinucleated giant cells containing nuclei arranged in a wreath-like fashion. Since its first description, very rare cases of GSS with muscle involvement, large vessels involvement, or necrobiotic changes have been reported. We present an extraordinary case of GSS with all these unusual features developing in the lesions of the same patient. The long follow-up of seven years allowed us to document the evolution of each lesion. Some lesions appeared and evolved in a manner very reminiscent of those of "parapsoriasis en plaques", others were classical GSS lesions, and still others developed large ulcerated lesions. These ulcerated lesions consistently failed to respond to conventional wound therapy, skin directed therapy [retinoids + psoralen combined with ultraviolet A (PUVA)-therapy], and interferon-alpha therapy. Remarkably, the ulcers completely healed when systemic corticosteroids were added. We hence postulate that the ulcers appeared because of large vessel vasculitis rather than tumoral direct destruction.

    To evaluate the radiologic findings of granulomatous colitis on double contrast barium enema and changes on follow-up studies. Serial double contrast barium enema of six patients with granulomatous colitis confirmed by endoscopic biopsy were reviewed. We analyzed the radiologic findings and their follow-up changes, including aphthous ulcers, lymphoid hyperplasia, deep ulcers, cobble stone appearance, geographic ulcers, asymmetric involvement of ulcers, skip lesions, sinus tract, fistula formation, pseudosacculation, focal stricture, and small bowel involvement. Pretreatment double contrast barium enema findings were aphthous ulcers in five patients, deep ulcer in six, cobble stone appearance in five, longitudinal geographic ulcers in two, fistulas in one, pseudosacculations in two, focal stricture in one, and pseudopolyps in six. Also, anal ulcers were observed in two patients, asymmetric involvement of ulcers in three, skip lesions in four, and small bowel involvement in five in five patients proved to have inactive disease after treatment, aphthous ulcers and deep ulcers disappeared. Geographic ulcers of two patients and anal ulcer of one patients decreased in size or depth. Pseudosacculation in one patient disappeared. Pseudopolyps decreased in two patients, increased in one, and decreased after increase in two. One patient whose disease remained active after treatment showed maintenance or increase of ulcers or fistula. And their pseudosacculation or focal stricture unchanged and pseudopolyps decreased. The major radiologic findings of chronic granulomatous colitis on double contrast barium enema are aphthous ulcer, deep ulcer, cobble stone appearance, discontinuity of the lesion and coexistence of ulcers and pseudopolyps. And, double contrast barium enema is good follow-up modality because its findings correlate with clinical course of the granulomatous colitis after treatment

    Nowadays, necrotizing cutaneous reaction after a tattoo is rare especially with the sterile tattoo equipment and antisepsis rules. We report the rare case of a necrotizing reaction secondary to a granulomatous reaction after a red tattoo, with a satellite node. A 40-year-old patient suffering from a granulomatous reaction to red dye of a large pectoral tattoo, with cutaneous and sub-cutaneous necrosis, and an infected axillary node. This pectoral tattoo also triggered a necrotizing granulomatous reaction on red-pigmented areas of other older tattoos. Local treatments (dressings, antibiotics, repeated excisions of necrotizing tissues) did not stop the allergic reaction, and an infectious origin was eliminated. The patient asked for a complete excision of the pectoral tattoo. Black intramacrophagic pigment was found in the black lymph node analysed. We did not experience any complications and the patient is satisfied with the results. Very few examples of cutaneous necrotizing secondary to a tattoo have been found in the literature. The hypothesis of a primitive infection that had secondarily led to necrosis is refuted by the lack of infective structures found in the analysed node, and most of all by the same reaction on other older tattoos on red-pigmented areas. This rare complication must be known by plastic surgeons, who will probably be called upon to take care of more and more tattooed patients. Even if it's rare, necrosis with a granulomatous reaction to red pigment after a tattoo must be known. This case illustrates a very violent immune reaction where infection was not proved.

    Granulomatous myocarditis may develop into cardiomyopathy and severe congestive heart failure that requires implantation of a left ventricular assist device (LVAD). Left ventricular (LV) core samples were collected from 177 patients with severe heart failure at the time of LVAD implantation, and samples were histologically examined and graded for severity of hypertrophy and fibrosis. Granulomatous myocarditis incidentally seen in a subset of samples was characterized by staining and culturing for mycobacteria and fungi. Various clinical parameters in these patients were analyzed. Of the 177 LV core samples examined, 6 (3.4%) showed nonnecrotizing granulomatous inflammation in the myocardial wall. Stains and cultures for mycobacteria and fungi were negative. All six patients [three women, three men; five African American, one Asian; mean age, 52±9 years (range, 41-61 years)] had arrhythmias and required an automatic implantable cardioverter defibrillator. Before LVAD implantation, the patients' mean cardiac index was 1.8±0.4 l/min/m(2); cardiac output, 2.9±0.6 l/min; and ejection fraction, 20±2%. One year after LVAD implantation, one patient had undergone heart transplantation. At 2 years, a second patient was transplanted, and one died. At 3 years, a third patient was transplanted and died postoperatively; two patients remained on support. No clinical evidence indicated involvement of other organs or recurrence in the transplanted patients. The incidental diagnosis of granulomatous myocarditis in our patients indicates that histological study of LV core samples in patients who undergo LVAD implantation may contribute to the diagnosis and be a consideration in the management of the underlying cause of heart failure. © 2013.

    Annexin II on mesangial cell surface mediates the binding of anti-dsDNA antibodies and consequent downstream inflammatory and fibrotic processes. We investigated the clinical relevance of circulating annexin II-binding immunoglobulins (Igs) in patients with severe proliferative lupus nephritis, and renal annexin II expression in relation to progression of nephritis in New Zealand Black and White F1 mice (NZBWF1/J) mice. Annexin II-binding Igs in serum were measured by ELISA. Ultrastructural localization of annexin II was determined by electron microscopy. Seropositivity rates for annexin II-binding IgG and IgM in patients with active lupus nephritis were significantly higher compared with controls (8.9%, 1.3% and 0.9% for annexin II-binding IgG and 11.1%, 4.0% and 1.9% for annexin II-binding IgM for patients with active lupus nephritis, patients with non-lupus renal disease and healthy subjects respectively). In lupus patients, annexin II-binding IgM level was higher at disease flare compared with remission. Annexin II-binding IgG and IgM levels were associated with that of anti-dsDNA and disease activity. Annexin II-binding IgG and IgM levels correlated with histological activity index in lupus nephritis biopsy samples. In NZBWF1/J mice, serum annexin II-binding IgG and IgM levels and glomerular annexin II and p11 expression increased with progression of active nephritis. Annexin II expression was present on mesangial cell surface and in the mesangial matrix, and co-localized with electron-dense deposits along the glomerular basement membrane. Our results show that circulating annexin II-binding IgG and IgM levels are associated with clinical and histological disease activity in proliferative lupus nephritis. The co-localization of annexin II and p11 expression with immune deposition in the kidney suggests pathogenic relevance. © 2017 The Author(s). published by Portland Press Limited on behalf of the Biochemical Society.

    Pediatric systemic lupus erythematosus (pSLE) patients often initially present with more active and severe disease than adults, including a higher frequency of lupus nephritis. Specific autoantibodies, including anti-C1q, anti-DNA and anti-alpha-actinin, have been associated with kidney involvement in SLE, and DNA antibodies are capable of initiating early-stage lupus nephritis in severe combined immunodeficiency (SCID) mice. Over 100 different autoantibodies have been described in SLE patients, highlighting the need for comprehensive autoantibody profiling. Knowledge of the antibodies associated with pSLE and proliferative nephritis will increase the understanding of SLE pathogenesis, and may aid in monitoring patients for renal flare. We used autoantigen microarrays composed of 140 recombinant or purified antigens to compare the serum autoantibody profiles of new-onset pSLE patients (n = 45) to healthy controls (n = 17). We also compared pSLE patients with biopsy-confirmed class III or IV proliferative nephritis (n = 23) and without significant renal involvement (n = 18). We performed ELISA with selected autoantigens to validate the microarray findings. We created a multiple logistic regression model, based on the ELISA and clinical information, to predict whether a patient had proliferative nephritis, and used a validation cohort (n = 23) and longitudinal samples (88 patient visits) to test its accuracy. Fifty autoantibodies were at significantly higher levels in the sera of pSLE patients compared to healthy controls, including anti-B cell-activating factor (BAFF). High levels of anti-BAFF were associated with active disease. Thirteen serum autoantibodies were present at significantly higher levels in pSLE patients with proliferative nephritis than those without, and we confirmed five autoantigens (dsDNA, C1q, collagens IV and X and aggrecan) by ELISA. Our model, based on ELISA measurements and clinical variables, correctly identified patients with proliferative

    Treatment options for systemic lupus erythematosus (SLE) and lupus nephritis (LN) have high associated morbidity and mortality. Side effects, particularly from long-term corticosteroid usage, limit patient adherence, with subsequent impacts on treatment efficacy. In addition, a subset of patients with SLE/LN fails to respond to current standard immunotherapy. There is an urgent need to develop steroid-sparing treatment regimens as well as novel therapies for the management of refractory disease. Rituximab is a chimeric mouse/human monoclonal antibody directed against the B cell CD20 receptor. It has been used in the treatment of non-Hodgkin's lymphoma for over 30 years and has an excellent safety profile. Recent work has demonstrated a role for B cell depletion therapy in the management of autoimmune disease, and the efficacy of rituximab in many observational studies in SLE and LN has been noted. Unfortunately, two large randomised controlled trials evaluating rituximab for the treatment of renal and non-renal lupus failed to meet their primary endpoints. Reasons for this have been discussed extensively within the medical community with a general consensus that trial design (steroid use, trial size and endpoints used) was the principal reason for the failures. Despite the lack of trial evidence, clinical experience means many physicians firmly believe in the value of rituximab in SLE/LN treatment and have continued to use it in their clinical practice. Recent work has demonstrated the efficacy of rituximab as a steroid-sparing agent and as an alternative therapeutic option for refractory SLE/LN. There are two further rituximab randomised controlled trials planned/started in LN – one using a steroid-minimising regimen with rituximab for induction and one evaluating rituximab for LN refractory to 6 months standard of care treatment. Rituximab remains a problematic drug in lupus and LN – it is a biologically plausible agent with a huge amount of supportive

    Urinary biomarkers may help in identification, treatment and assessment of response in patients with lupus nephritis (LN). Osteoprotegerin (OPG) is produced by the kidneys and lymphoid cells and may reflect renal disease activity better. The data on its utility are sparse. Fifty-eight patients with active LN (AN), 24 with active non-renal disease (ANR) and 39 with inactive disease (ID) were included. Median disease duration was 32 (1-204) months and median age was 27 (12-50) years. AN patients were followed up every three months for one year. Urine and serum samples were collected for OPG measurement by ELISA (pg/ml) and urinary values were normalised for creatinine excretion (pg/mg). Urine samples from 24 healthy individuals (HCs) and 20 patients each of rheumatoid arthritis (RA) and diabetic nephropathy (DM) served as controls. Variables were expressed as median (range). At baseline, normalised urinary OPG (uOPG) was significantly higher (p < 0.001) in AN (1229 (0-8577)) than ANR (236 (0-14713)), ID (463 (7-4253)), HCs (366 (120-2849)) and DM (350 (127-1577)) but it was not different from RA (1511 (122-8849)). uOPG correlated modestly with rSLEDAI (r = 0.4, p < 0.001) and SLEDAI (r = 0.31, p < 0.001) but not with serum OPG (sOPG). uOPG but not sOPG could differentiate between AN and ANR groups. In the longitudinal study, uOPG and sOPG decreased significantly with treatment at all follow-up visits but the trend of fall in sOPG was erratic. uOPG values at baseline, 3, 6, 9 and 12 months were 1229 (0-8577), 466 (3-4874), 104 (0-1598), 325 (0-4025) and 555 (6-6771) pg/mg, respectively. uOPG but not sOPG rose before conventional markers in three patients who had a relapse of LN. In two patients who developed chronic kidney disease, uOPG remained persistently high. For differentiating AN from ANR patients, uOPG performed the best on receiver operator characteristics analysis (AUC = 0.72) when compared with anti-dsDNA antibodies, C3, C4 and s

Phagocytosed parasites were noted within the giant cells. Vascularization of the corneal stroma was noted in two cases. Immunophenotyping revealed a predominance of T lymphocytes and macrophages. Clinically, four of five cases had shown features of limbal and scleral involvement. Conclusion: Granulomatous inflammation in the posterior corneal stroma, is not an uncommon finding in Acanthamoeba keratitis and could possibly be immune-mediated, contributing to persistence and progression of disease. Clinical Relevance: Presence of granulomatous inflammation in Acanthamoeba keratitis, in most cases is associated with limbal and scleral involvement and therefore could be considered as one of the poor prognostic markers. Further studies are required to ascertain the specific clinical features and appropriate management strategies in these cases.

    Full Text Available Idiopathic granulomatous myocarditis is extremely rare, particularly since the introduction of drugs effective against tuberculosis (TB, viruses, fungi and the effective treatment of sarcoidosis. Here is a case of a 65-year-old female prisoner having history of sudden collapse and ultimately death. Autopsy findings of various viscera on histopathological examination show granulomatous pathology, that is, in spleen, liver and in the left ventricular wall of heart. Ziehl-Neelsen staining of the sections show the absence of acid fast bacilli, negative for fungal staining as most of the granulomas are noncaseating type with presence of giant cells having no asteroid body and Schuamann body, real-time polymerase chain reaction for TB is negative. Idiopathic giant cell myocarditis is a disease of relatively young adults, that is, between 3 rd and 4 th decade of life. So, this case is strongly considered to be a case of sudden death due to myocarditis as a result of idiopathic systemic granulomatous pathology, a rare case in in literature.

    Dengue viremia may be the trigger for immune complex formation in patients who are predisposed to developing autoimmune disease. We report a rare case of dengue virus infection evolving into systemic lupus erythematosus (SLE) and lupus nephritis. To the best of our knowledge this is the first case of dengue fever evolving into lupus nephritis. A 22 year old female presented with having had high grade fever, skin rash, breathlessness, retro-orbital pain, abdominal pain, arthralgias and myalgias for 10 days. She tested positive for dengue immunoglobulin M (IgM). She was given supportive treatment and was subsequently discharged. Four weeks later she developed recurrent fever, arthralgia, rash and anasarca. She was suspected as having SLE with active lupus nephritis. Antinuclear antibody (ANA), and anti double stranded deoxyribonucleic acid (anti dsDNA) titers were positive and complements were low. Renal biopsy showed diffuse proliferative glomerulonephritis grade IV. She was treated with steroids and immunosuppressants to which she responded. Dengue viremia incites antibody production, which if excessive causes deposition of viral antigen-antibody immune complexes. This could possibly lead to renal tubular damage and glomerulonephritis in susceptible individuals. Dengue fever leading to development of glomerulonephritis is rarely seen. Our patient developed dengue fever and after a month presented with manifestations of SLE and lupus nephritis. Both dengue fever and SLE have common manifestations of fever, arthralgia, rash, leucopenia with thrombocytopenia and serositis. Bacterial and viral infections may act as a 'trigger' for starting or relapsing lupus activity in genetically predetermined individuals. In our case it may be possible that dengue virus could have triggered a dysfunctional immune response, resulting in the developing of autoimmunity and SLE with lupus nephritis.

    Interstitial cystitis (IC) does not start as an endstage disease, it has a beginning when symptoms are milder, intermittent and the disease is misdiagnosed. To determine how IC develops patients were interviewed on when their symptoms began, what they were and are now as well as the various diagnoses that they received before they were determined to have IC. One hundred female IC patients were screened. They filled out a questionnaire asking about the age their disease presented, their initial and current symptoms, what their original diagnoses were, effect of the menstrual cycle and sexual activity on their symptoms and about any relatives with bladder symptoms or a current diagnosis of IC. By age 30, 81% of patients had bladder symptoms, 21% before age 10. The first symptom was frequency in 81%, pain present in 59% and the symptoms were intermittent in 64%. Most common early misdiagnosis was UTI in 74% with 93% reporting negative urine cultures. Sex was painful and causes symptom flares in 82%, symptoms flared the week before the menses in 75%. Most common gynecologic diagnosis was yeast vaginitis, 42%. Urge incontinence was present in 33%. There were 51% that reported bladder symptoms in a first degree female relative. IC begins primarily with frequency and is intermittent in most patients with symptom flares associated with sexual activity. Pain and urgency incontinence tend to be a later symptoms. When IC flares the most common misdiagnosis is UTI. Symptoms begin before age 30 in most but an IC diagnosis is often not made until age 40. Genetics appear to play a significant role. It is important to consider these facts when evaluating women with "early IC" because correct diagnosis will result in proper therapy and reduced health care costs.

    Interstitial lung diseases (ILD, diffuse lung diseases) are a heterogeneous group of diseases in which a pathological process primarily involved alveoli and perialveolar interstitium, resulting in impaired gas exchange, restrictive changes of lung ventilation function and diffuse interstitial changes detectable by X-ray. Children's interstitial lung diseases is an topical problem ofpediatricpulmonoogy. The article presents current information about classification, epidemiology, clinical presentation, diagnostics, treatment and prognosis of these rare diseases. The article describes the differences in the structure, pathogenesis, detection of various histological changes in children's ILD compared with adult patients with ILD. Authors cite an instance of registers pediatric patients with ILD. The clinical semiotics of ILD, the possible results of objective research, the frequency of symptoms, the features of medical history, the changes detected on chest X-rays, CT semiotics described in detail. Particular attention was paid to interstitial lung diseases, occurring mainly in newborns and children during the first two years of life, such as congenital deficiencies of surfactant proteins, neuroendocrine cell hyperplasia of infancy, pulmonary interstitial glycogenosis. The diagnostic program for children's ILD, therapy options are presented in this article.

  3. Kallikrein transduced mesenchymal stem cells protect against anti-GBM disease and lupus nephritis by ameliorating inflammation and oxidative stress.

    Full Text Available Previously we have shown that kallikreins (klks play a renoprotective role in nephrotoxic serum induced nephritis. In this study, we have used mesenchymal stem cells (MSCs as vehicles to deliver klks into the injured kidneys and have measured their therapeutic effect on experimental antibody induced nephritis and lupus nephritis. Human KLK-1 (hKLK1 gene was transduced into murine MSCs using a retroviral vector to generate a stable cell line, hKLK1-MSC, expressing high levels of hKLK1. 129/svj mice subjected to anti-GBM induced nephritis were transplanted with 10(6 hKLK1-MSCs and hKLK1 expression was confirmed in the kidneys. Compared with vector-MSCs injected mice, the hKLK1-MSCs treated mice showed significantly reduced proteinuria, blood urea nitrogen (BUN and ameliorated renal pathology. Using the same strategy, we treated lupus-prone B6.Sle1.Sle3 bicongenic mice with hKLK1-MSCs and demonstrated that hKLK1-MSCs delivery also attenuated lupus nephritis. Mechanistically, hKLK1-MSCs reduced macrophage and T-lymphocyte infiltration into the kidney by suppressing the expression of inflammation cytokines. Moreover, hKLK1 transduced MSCs were more resistant to oxidative stress-induced apoptosis. These findings advance genetically modified MSCs as potential gene delivery tools for targeting therapeutic agents to the kidneys in order to modulate inflammation and oxidative stress in lupus nephritis.

    To identify factors contributing to cognitive impairment in children with lupus nephritis. A cross-sectional analysis of a large multicenter national cohort of children with chronic kidney disease (CKD) using standardized measures to determine baseline neuropsychiatric function and health-related quality of life (HRQoL) in children with lupus nephritis (n = 34), and to compare baseline function with that in children with other forms of glomerular CKD (gCKD; n = 171). We used inverse probability weighting via a logistic model for propensity score analysis to achieve balance between children with lupus nephritis and those with other glomerular causes of CKD, adjusting for known confounders. We used linear regression models to compare neurocognitive outcomes between exposure groups, adjusting for current prednisone use and testing for an interaction between current prednisone use and lupus nephritis, and to test for an association between cognitive function and HRQoL. Current prednisone use was independently associated with worse attention (P children with lupus nephritis on prednisone (P = .047). Better parent-reported HRQoL was associated with better visual memory (P = .01), and better child-reported HRQoL was associated with better attention (P Children with lupus nephritis have comparable or better cognitive function than their peers with other gCKDs, which is reassuring given the multiorgan and lifelong complications associated with lupus.

    Full Text Available Background: The prognosis of SLE is int1uenced by the onset of glomerulonephtitis. Clinical ttials in lupus nephritis have demonstrated that cyclophosphamide therapy is the superior regimen in the management oflupus nephritis for preserving renal function.Objective:The purpose of this study is to define the outcome of renal function with bolus pu lses of cyclophosphamide and steroid according to our protocol and also to determine an appropriate pattern of treatment of lupus nephritis. Methods: In this open-label clinical triaL to evaluate the results, the short-term prognosis and the rate of complications of an immunosuppressive regimen with corticosteroids and cyclophosphamide, twenty-five patients with biopsy-proven lupus nephritis were studied. Treatment was structured in 4 phases: I Induction with bolus methylprednisolone and cyclophosphamide. 2 Maintenance with oral prednisolone for 4 weeks and monthly cyclophosphamide pulses for 6 months. 3 Tapeting with reduction of prednisolone by 10% each month and continuing cyclophosphamide every other month till one year and for the second year every 3 months. 4 Discontinuation with oral prednisolone slowly tapered to the least effective daily dose and cyclophosphamide discontinued after 2 yr of therapy. We defined primary outcome measures according to these criteria: renal function return to normal limits or become stable, regression of systemic and local inflammatory symptoms. urine protein excretion h1lling below 0.3 gr/ elL or by at least SOo/c. RBC cast disappearance, C3, C4, Hb, and ESR return to notmallimits. Result: Twenty-three patients wi th lupus nephritis completed our therapeutic protocol. Renal biopsy was perfonned in 22 cases and indicated type IV in 20 patients (95.2%, and type V in 2 patients. After an average of 4+ 1.95 months 22 patients achieved remission (95.65% and only one case remained non-responsive. She became pregnant in her fourth month of therapy. Significant

    2002-01-01

    Idiopathic interstitial pneumonias are at present classified as one of four types: usual, nonspecific, acute, or desquamative. The acute form has the worst prognosis, followed by the usual and the nonspecific form; it is in desquamative cases that prognosis is best. At high-resolution CT, usual interstitial pneumonia, the most frequent type, manifests as patchy subpleural areas of ground-glass attenuation, irregular linear opacity, and honeycombing, which the nonspecific type, the second most frequent, appears as subpleural patchy areas of ground-glass attenuation with associated areas of irregular linear opacity. Acute interstitial pneumonia demonstrates extensive bilateral airspace consolidation and patchy or diffuse bilateral areas of ground-glass attenuation in middle and lower lung zones

    Interstitial Cystitis, first described in 1887 as an inflammatory disease of the bladder wall, is now regarded as a very common disease with an estimated number of unreported cases. Reasons for underdiagnosis is the widespread use of strict exclusion criteria. The disease can already be suspected by a careful medical history and physical examination in an early stage and then be treated with promising multimodal therapeutic approaches. In addition to a symptomatic oral therapy, local instillations with constituents of the protective glycosaminoglycan-layer are the most common therapeutic approach, because its defective integrity plays a key role in the pathogenesis of interstitial cystitis.

    Perfusion scintigraphy of the lungs has shown that a reverse direction of postural reactions of the pulmonary blood flow is observed in patients with mitral valvular disease. It is accounted for by the action of gravitation on capillary hydrostatic pressure resulting in the localization of interstitial edema in pulmonary venous hypertension mainly in the lower lung, its microcirculatory bed being compressed and the blood flow redistributed to the opposite upper lung. Therefore successive perfusion scintigraphy of the lungs in the vertical position and in the lateral position with a RP administered twice, can serve as a sensitive test for diagnosis of interstitial lung edema

    Objective: To evaluate SPECT/CT with radiolabeled somatostatin analogues (RSAs) in systemic granulomatous infections in comparison with gallium-67 ({sup 67}Ga) citrate scintigraphy. Materials And Methods: We studied 28 patients with active systemic granulomatous infections, including tuberculosis, paracoccidioidomycosis, pneumocystosis, cryptococcosis, aspergillosis, leishmaniasis, infectious vasculitis, and an unspecified opportunistic infection. Of the 28 patients, 23 had started specific treatment before the study outset. All patients underwent whole-body SPECT/CT imaging: 7 after injection of {sup 99m}Tc-EDDA-HYNIC-TOC, and 21 after injection of {sup 111}In-DTPA-octreotide. All patients also underwent {sup 67}Ga citrate imaging, except for one patient who died before the {sup 67}Ga was available. Results: In 20 of the 27 patients who underwent imaging with both tracers, 27 sites of active disease were detected by {sup 67}Ga citrate imaging and by SPECT/CT with an RSA. Both tracers had negative results in the other 7 patients. RSA uptake was visually lower than {sup 67}Ga uptake in 11 of the 20 patients with positive images and similar to {sup 67}Ga uptake in the other 9 patients. The only patient who did not undergo {sup 67}Ga scintigraphy underwent {sup 99m}Tc-EDDA-HYNIC-TOC SPECT/CT-guided biopsy of a lung cavity with focal RSA uptake, which turned to be positive for aspergillosis. Conclusion: SPECT/CT with {sup 99m}Tc-EDDA-HYNIC-TOC or {sup 111}In-DTPA-octreotide seems to be a good alternative to {sup 67}Ga citrate imaging for the evaluation of patients with systemic granulomatous disease.

    2017-01-01

    Full Text Available An estimated 0.9% to 2.4% of patients with systemic lupus erythematosus (SLE also have hemophagocytic lymphohistiocytosis (HLH. HLH associated with autoimmune diseases is often refractory to corticosteroid treatment; thus, additional immunosuppressive drugs, such as cyclosporine, cyclophosphamide, or tacrolimus, are required. Here, we describe the case of a 44-year-old Japanese woman who developed HLH associated with lupus nephritis. Initially, her HLH was refractory to treatment with a corticosteroid, tacrolimus, and mizoribine. However, alternative treatment with a corticosteroid, mycophenolate mofetil, and tacrolimus improved both her HLH and lupus nephritis. This case suggests the possibility of mycophenolate mofetil as a key drug for treating HLH associated with SLE.

    2011-12-01

    The pathogenesis of systemic lupus erythematosus (SLE) has been attributed to complex interactions between genetic, hormonal and environmental factors. The influence of a genetic predisposition to SLE is supported by family aggregation and a high concordance rate in monozygotic twins. Here we present a rare case of simultaneous presentation of SLE and lupus nephritis in a mother and son. Both patients had nephrotic-range proteinuria, and the renal pathological classifications of the son and his mother were Class IV-G (A) and Class III (A/C), respectively, according to the International Society of Nephrology/Renal Pathology Society (ISN/RPS) 2003 classification of lupus nephritis. Apart from the renal involvement, both patients had leucopenia and anemia, and the mother also had typical cutaneous lesions and secondary Sjögren's syndrome. This case supports the genetic role in the etiology of SLE, and displayed different clinical presentations and disease severity in familial SLE patients of different gender and age.

    Twin ectopic pregnancy is an uncommon event, usually occurring as simultaneous intrauterine and tubal gestations. Interstitial implantation of an ectopic pregnancy is also a rare event, associated with a high mortality rate. Twin interstitial pregnancy has been previously reported only three times in the English literature. We report a recent case of unilateral twin interstitial ectopic pregnancy that resulted in maternal death and review the literature with regard to both ectopic pregnancy and factors associated with mortality from interstitial implantation.

    Wegener's granulomatosis is a clinico-pathological entity characterized by necrotizing granulomatous angiitis involving the upper- and/or lower respiratory tract and the kidneys. Renal involvement is usually characterized by a rapidly progressive necrotizing glomerulonephritis. A case is presented of a patient who developed renal failure and presented a solitary pseudotumoral lesion in the upper pole of the left kidney. Imaging characteristics on US, CT and MR imaging are discussed. The diagnosis was confirmed with ultrasound-guided needle biopsy. (orig.)

    International audience; Lupus nephritis (LN), one of the most severe outcomes of systemic lupus erythematosus (SLE), is initiated by glomerular deposition of immune-complexes leading to an inflammatory response and kidney failure. Autoantibodies to nuclear antigens and autoreactive B and T cells are central in SLE pathogenesis. Immune mechanisms amplifying this autoantibody production drive flares of the disease. We previously showed that basophils were contributing to LN development in a spo...

    Seventeen patients with intractable lupus nephritis and nephrotic syndrome were treated with total lymphoid irradiation. Statistically significant improvement in mean renal disease and serologic activity parameters occurred within 3 months and persisted for at least 3 years. Although there was a marked reduction of T helper cell numbers and function after total lymphoid irradiation, recovery of these parameters was not associated with a return of disease activity. Risks of sterility, severe infections, and hematologic malignancy appeared to be lower than with alkylating agents.

    Granulocyte colony-stimulating factor (G-CSF) can induce regulatory T cells (Tregs) as well as myeloid-derived suppressor cells (MDSCs). Despite the immune modulatory effects of G-CSF, results of G-CSF treatment in systemic lupus erythematosus are still controversial. We therefore investigated whether G-CSF can ameliorate lupus nephritis and studied the underlying mechanisms. NZB/W F1 female mice were treated with G-CSF or phosphate-buffered saline for 5 consecutive days every week from 24 weeks of age, and were analyzed at 36 weeks of age. G-CSF treatment decreased proteinuria and serum anti-dsDNA, increased serum complement component 3 (C3), and attenuated renal tissue injury including deposition of IgG and C3. G-CSF treatment also decreased serum levels of BUN and creatinine, and ultimately decreased mortality of NZB/W F1 mice. G-CSF treatment induced expansion of CD4 + CD25 + Foxp3 + Tregs, with decreased renal infiltration of T cells, B cells, inflammatory granulocytes and monocytes in both kidneys and spleen. G-CSF treatment also decreased expression levels of MCP-1, IL-6, IL-2, and IL-10 in renal tissues as well as serum levels of MCP-1, IL-6, TNF-α, IL-10, and IL-17. When Tregs were depleted by PC61 treatment, G-CSF-mediated protective effects on lupus nephritis were abrogated. G-CSF treatment ameliorated lupus nephritis through the preferential expansion of CD4 + CD25 + Foxp3 + Tregs. Therefore, G-CSF has a therapeutic potential for lupus nephritis.

    Within nuclear medicine there is a trend towards quantitative analysis. Gallium renal scan has been reported to be useful in monitoring the disease activity of lupus nephritis. However, only visual interpretation using a four-grade scale has been performed in previous studies, and this method is not sensitive enough for follow-up. In this study, we developed a semi-quantitative method for gallium renal scintigraphy to find a potential parameter for the evaluation of lupus nephritis. Forty-eight patients with lupus nephritis underwent renal biopsy to determine World Health Organization classification, activity index (AI) and chronicity index (CI). A delayed 48-h gallium scan was also performed and interpreted by visual and semi-quantitative methods. For semi-quantitative analysis of the gallium uptake in both kidneys, regions of interest (ROIs) were drawn over both kidneys, the right forearm and the adjacent spine. The uptake ratios between these ROIs were calculated and expressed as the ''kidney/spine ratio (K/S ratio)'' or the ''kidney/arm ratio (K/A ratio)''. Spearman's rank correlation test and Mann-Whitney U test were used for statistical analysis. Our data showed a good correlation between the semi-quantitative gallium scan and the results of visual interpretation. K/S ratios showed a better correlation with AI than did K/A ratios. Furthermore, the left K/S ratio displayed a better correlation with AI than did the right K/S ratio. In contrast, CI did not correlate well with the results of semi-quantitative gallium scan. In conclusion, semi-quantitative gallium renal scan is easy to perform and shows a good correlation with the results of visual interpretation and renal biopsy. The left K/S ratio from semi-quantitative renal gallium scintigraphy displays the best correlation with AI and is a useful parameter in evaluating the disease activity in lupus nephritis. (orig.)

    Radiologic findings of four cases of acute focal nephritis and their clinical correlation are presented. They were studied by means of echography and computerized tomography (CT). The latter was the technique of choice for their diagnosis in the study carried out after intravenous radiopaque contrast injection because of its sensitivity and specificity. The literature on this topic is reviewed and some guidelines for diagnosis and differential diagnosis are proposed. (Author)

    Interstitial cystitis/painful bladder syndrome affects more than 1 million persons in the United States, but the cause remains unknown. Most patients with interstitial cystitis/painful bladder syndrome are women with symptoms of suprapubic pelvic and/or genital area pain, dyspareunia, urinary urgency and frequency, and nocturia. It is important to exclude other conditions such as infections. Tests and tools commonly used to diagnose interstitial cystitis/painful bladder syndrome include specific questionnaires developed to assess the condition, the potassium sensitivity test, the anesthetic bladder challenge, and cystoscopy with hydrodistension. Treatment options include oral medications, intravesical instillations, and dietary changes and supplements. Oral medications include pentosan polysulfate sodium, antihistamines, tricyclic antidepressants, and immune modulators. Intravesical medications include dimethyl sulfoxide, pentosan polysulfate sodium, and heparin. Pentosan polysulfate sodium is the only oral therapy and dimethyl sulfoxide is the only intravesical therapy with U.S. Food and Drug Administration approval for the treatment of interstitial cystitis/painful bladder syndrome. To date, clinical trials of individual therapies have been limited in size, quality, and duration of follow-up. Studies of combination or multimodal therapies are lacking.

    2014-01-01

    Full Text Available Introduction. Desquamative interstitial pneumonia is one of the rarest idiopathic interstitial pneumonias and the rarest form of smoking-related interstitial lung diseases. It was first described by Liebow in 1965. Histologically, it is characterized by the presence of eosinophilic macrophages uniformly filling airspaces which often contain a finely granular light-brown pigment that does not stain for hemosiderin. The alveolar walls are usually mildly thickened by fibrous tissue and infiltrated by a moderate number of lymphocytes. Case Outline. Our patient was a 56-year-old male, heavy smoker, with bilateral lung infiltrations of unknown etiology and several months of discomfort in the form of dry cough and shortness of breath. Lung function tests showed a moderate restrictive ventilation disorder and a severe reduction of diffusing capacity. Since bronchoscopic specimens did not reveal lung lesion etiology, an open lung biopsy of the lower left pulmonary lobe was performed, and based on the obtained surgical material the pathohistologically diagnosis of desquamative interstitial pneumonia was established. The patient was started on corticosteroid and immunosuppressive therapy, and he ceased smoking. At the last control examination, two years after the onset of symptoms, the patient was feeling well, and high-resolution computed tomography (HRCT scan of the thorax showed regression of pathological changes. Conclusion. Although, as in our case, the majority of DIP patients improve on treatment, some patients still develop progressive irreversible fibrosis despite therapy.

    Bullous systemic lupus erythematosus (BSLE) is an autoimmune blistering disease occurring in patients with systemic lupus erythematosus (SLE). It is a rare disease, especially in children. A 14-year-old girl initially presented with fatigue, generalized vesiculobullous skin lesions, and ulcers over the hard palate and oral mucosa. Clinical investigations revealed hematuria and proteinuria, a high erythrocyte sedimentation rate and titer of antinuclear antibody, and anti-double-stranded DNA. Skin biopsy findings were suggestive of BSLE. A renal biopsy confirmed the features of class V lupus nephritis. Based on the clinical features and investigations, a diagnosis of BSLE with nephritis was made. She received methylprednisolone pulse therapy and hydroxychloroquine; however, it did not alleviate the vesiculobullous eruption, so treatment with dapsone started and resulted in the dramatic disappearance of the lesions. Interruption of dapsone due to hemolysis did not aggravate the bullous disease. During follow-up, she had multiple flare-ups of disease and nephritis without rebound of bullous lesions. BSLE is a rare presentation of SLE in children. Differentiating it from other skin bullous diseases and SLE with blister is important for the correct management. The unusual presentation of this disease may delay the diagnosis and therefore requires a high index of clinical suspicion.

    Full Text Available The therapeutic effect of polysaccharide of large yellow croaker swim bladder (PLYCSB on lupus nephritis has been studied in vivo. A high concentration (50 mg/kg dose of PLYCSB reduced the levels of serum inflammatory cytokine levels of IL-6, IL-12, TNF-α and IFN-γ compared to a low concentration (25 mg/kg dose and control mice. SCr, BUN, TC and TG serum levels of PLYCSB treated mice were lower than those of control mice, and TP and ALB serum levels were higher than control mice. Control mice tested ds-DNA positive at the 6th week, and 50 mg/kg treated mice tested at the 10th week after the experiment began. The output of urine protein of 50 mg/kg PLYCSB treated mice was most closely comparable to the normal mice. The glomerular number of 50 mg/kg PLYCSB treated mice was more than the 25 mg/kg dose and control groups, and the 50 mg/kg dose group showed the lowest glomerular sclerosis index in lupus nephritis mice. By RT-PCR and western blot assay, PLYCSB significantly induced inflammation in kidney tissues of mice by downregulating NF-κB-p65, TGF-β1, Fas, FasL and upregulating IκB-α. These results suggest that PLYCSB showed a potential curative effect on lupus nephritis as a drug or functional food.

    2013-01-01

    Full Text Available Tubulointerstitial nephritis and uveitis (TINU syndrome is a rare disorder defined by the combination of biochemical abnormalities, tubulointerstitial nephritis, and uveitis. We describe a 12-year-old female, presented with a ten-day history of fever, characterized by sudden onset and rapid spontaneous resolution in few hours, accompanied by shivering, extreme fatigue, and loss of appetite. Laboratory values were consistent with renal failure of tubular origin. Renal biopsy confirmed a tubulointerstitial nephritis, with acute tubulitis, polymorphonuclear infiltration, and microabscesses. The renal interstitium was occupied by a dense inflammatory infiltrate, consisting of lymphocytes, plasma cells, and neutrophils. Glomerular structures were preserved. Ophthalmological examination that suggested a previous asymptomatic bilateral uveitis and HLA typing (HLA-DQA1*0101/0201 and HLA-DQB1*0303/0503 further supported the suspect of TINU syndrome. TINU syndrome is probably an underdiagnosed disorder, responsible for many cases of idiopathic anterior uveitis in young patients, especially in those who have asymptomatic renal disease and when proper diagnostic tests are not performed at the time of presentation.

    2017-12-01

    Nephritis is one of the most severe complications of systemic lupus erythematosus (SLE). One key characteristic of lupus nephritis (LN) is the deposition of immune complexes containing nucleic acids and/or proteins binding to nucleic acids and autoantibodies recognizing these molecules. A variety of cell death processes are implicated in the generation and externalization of modified nuclear autoantigens and in the development of LN. Among these processes, apoptosis, primary and secondary necrosis, NETosis, necroptosis, pyroptosis, and autophagy have been proposed to play roles in tissue damage and immune dysregulation. Cell death occurs in healthy individuals during conditions of homeostasis yet autoimmunity does not develop, at least in part, because of rapid clearance of dying cells. In SLE, accelerated cell death combined with a clearance deficiency may lead to the accumulation and externalization of nuclear autoantigens and to autoantibody production. In addition, specific types of cell death may modify autoantigens and alter their immunogenicity. These modified molecules may then become novel targets of the immune system and promote autoimmune responses in predisposed hosts. In this review, we examine various cell death pathways and discuss how enhanced cell death, impaired clearance, and post-translational modifications of proteins could contribute to the development of lupus nephritis.

    Presenting our experience concerning interstitial pregnancies (IP) surgical management and to evaluate our patients' subsequent long-term fertility. Twenty patients underwent surgical treatment of IP in our department over 15 years. In this retrospective study, we present symptoms that led to diagnosis, treatments, fertility and obstetrical outcome. Mean gestational age at diagnosis was 8SA, with a median BHCG rate of 7411 IU/L, and a patient mean age of 30 years. Ninety percent of patients had at least one risk factor for ectopic pregnancy. Pain or bleeding were the most common symptoms at admission, 4 patients were admitted in an hypovolemic shock status. Location of the interstitial ectopic pregnancy was discovered during surgery in 45 % of cases. Six patients had a large hemoperitoneum bigger than 1L, 5 patients had an IP of uterine stump after salpingectomy for a previous ectopic pregnancy. The most used surgical technique was in 60 % of cases the excision by Endo GIA stapling(®) with salpingectomy. Regarding fertility, 12 patients wished pregnancy in the aftermath of the intervention, 10 had at least one pregnancy, among them there is an ectopic contralateral ampullary pregnancy, and a contralateral recurrence of interstitial pregnancy. Four patients were delivered by cesarean section and 4 patients were delivered vaginally, some several times. No uterine rupture occured. Interstitial pregnancy is a rare ectopic pregnancy. Its diagnosis is difficult and may involve maternal life-threatening and fertility. In subsequent pregnancies, the clinician has to be careful concerning the risks of interstitial pregnancy recurrence and uterine rupture. Copyright © 2013. Published by Elsevier SAS.

    Despite the improvement in the prognosis of lupus nephritis (LN), the cardiovascular morbimortality remains high. The early recognition and remission of flares, while trying to avoid the metabolic adverse effects of medication, must be mandatory. The aim of our study was to assess the cardiovascular (CV) risk profile in a cohort of lupus patients with preserved kidney function after a nephritis episode, compared to patients without a nephritis flare. 130 patients diagnosed of SLE (32 with previous nephritis flare and 98 without) were studied in order to evaluate the CV risk profile, despite the preserved kidney function. The most prevalent risk factors were sedentary lifestyle (57.6%), overweight/obesity (38.3%) and dyslipidemia (36%), followed by smoking (32%) and hypertension (16%). Though more than a half (53.1%) was taking CV medication, a high percentage did not reach a therapeutic target value, especially regarding obesity (11.5%) and cholesterol levels (LDL-C of 16%). The prevalence of dyslipidemia (53.1% vs 30.6%), smoking (46.6% vs 27.5%), left ventricular hypertrophy (LVH) (21.4% vs 6.4%) and lower HDL-C (48.6mg/dL vs 55.4mg/dL) were significantly different in the group with previous nephritis flare. Moreover, young patients with lupus nephritis, received more pulses of corticosteroids and cyclophosphamide, had higher prevalence of hypertension, LVH, higher proteinuria, hospital admissions and waist circumference, constituting the subgroup of patients with greater aggregation of CV risk factors. Patients with previous nephritis flare showed a poor control of CV risk factors despite the preserved renal function, these patients would require a closer therapeutic management.

    Nodular sclerosing Hodgkin's lymphoma commonly presents with a mediastinal mass, but it rarely compresses or invades mediastinal structures or the anterior chest wall. Histologically, it can cause necrotizing granulomatous inflammation. A woman with a right breast mass extending from an asymptomatic large mediastinal mass selectively compressing the trachea is presented. A computed tomography-guided core needle biopsy from the anterior chest wall mass revealed necrotizing granulomatous inflammation. Finally, the diagnosis of nodular sclerosing Hodgkin's lymphoma was made by incisional biopsy. Clinical suspicion of nodular sclerosing Hodgkin's lymphoma is crucial since an adequate tissue diagnosis is needed when the initial less invasive diagnostic testing is inconclusive.

    Full Text Available Introduction: Although focal lupus nephritis (FLN with extracapillary proliferation (ECP is usually found in renal biopsies, little is known about its course. This study was carried out to investigate the correlation of clinical, histological and laboratory findings in these patients’ progress. Objective: To analyze focal or diffuse proliferative lupus nephritis biopsies (class III and IV, according to WHO and their development regarding the level of extracapillary proliferation throughout a period of 10 years at Hospital de Clínicas José de San Martín. Methods: In this retrospective observational study, 147 patients with class III or IV GN were observed for 10 years. According to the degree of extracapillary proliferation, they were divided into the following groups: group 1 (5%-50% of crescents, i.e. diffuse proliferative nephritis (DPN, n=20]. Patients suffering from class III and IV lupus nephritis with no extracapillary proliferation formed the control group (n=60. After one year, clinical and laboratory findings as well as the development of the condition among the four groups were compared to assess their level of remission. Complete remission was considered as defined in KDIGO 2012 Guideline. A univariate logistic regression analysis and a subsequent multivariate one were performed. Results: There were 124 women (84.35% and 23 men (15.65% with an average age of 35±10. The average age in the control group was 32±10. The univariate analysis showed a greater number of patients who achieved complete remission in the control group with an odds ratio of 0.05 (0.02-0.12 p=0.001, whereas in the 3 groups with extracapillary proliferation fewer patients reached this state, even in group 1, which had an odds ratio of 7.61 (2.42-23.9 and p=0.001. The multivariate analysis revealed that the persistent protein in the urine after 6 months was statistically significant for not achieving complete remission, the odds ratio being 2.81 (1

    Full Text Available Chronic granulomatous disease (CGD is a rare primary immune deficiency caused by mutations in genes coding for components of the nicotinamide adenine dinucleotide phosphate oxidase, characterized by severe and recurrent bacterial and fungal infections, together with inflammatory complications. Dysregulation of inflammatory responses are often present in this disease and may lead to granulomatous lesions, most often affecting the gastrointestinal (GI and urinary tracts. Treatment of inflammatory complications usually includes corticosteroids, whereas antimicrobial prophylaxis is used for infection prevention. Curative treatment of both infectious susceptibility and inflammatory disease can be achieved by hematopoietic stem cell transplantation. We report herein three patients with the same mutation of the CYBB gene who presented with very early-onset and severe GI manifestations of X-linked CGD. The most severely affected patient had evidence of antenatal inflammatory involvement of the GI and urinary tracts. Extreme hyperleukocytosis with eosinophilia and high inflammatory markers were observed in all three patients. A Mycobacterium avium lung infection and an unidentified fungal lung infection occurred in two patients both during their first year of life, which is indicative of the severity of the disease. All three patients underwent bone marrow transplantation and recovered fully from their initial symptoms. To our knowledge, these are the first reports of patients with such an early-onset and severe inflammatory manifestations of CGD.

    VanderHeyden Thomas R

    2012-01-01

    Full Text Available Abstract Background Bartonella henselae (B. henselae is considered a rare cause of granulomatous hepatitis. Due to the fastidious growth characteristics of the bacteria, the limited sensitivity of histopathological stains, and the non-specific histological findings on liver biopsy, the diagnosis of hepatic bartonellosis can be difficult to establish. Furthermore, the optimal treatment of established hepatic bartonellosis remains controversial. Case presentation We present a case of hepatic bartonellosis in an immunocompetent woman who presented with right upper quadrant pain and a five cm right hepatic lobe mass on CT scan. The patient underwent a right hepatic lobectomy. Surgical pathology revealed florid necrotizing granulomatous hepatitis, favoring an infectious etiology. Despite extensive histological and serological evaluation a definitive diagnosis was not established initially. Thirteen months after initial presentation, hepatic bartonellosis was diagnosed by PCR studies from surgically excised liver tissue. Interestingly, the hepatic granulomas persisted and Bartonella henselae was isolated from the patient's enriched blood culture after several courses of antibiotic therapy. Conclusion The diagnosis of hepatic bartonellosis is exceedingly difficult to establish and requires a high degree of clinical suspicion. Recently developed, PCR-based approaches may be required in select patients to make the diagnosis. The optimal antimicrobial therapy for hepatic bartonellosis has not been established, and close follow-up is needed to ensure successful eradication of the infection.

    2000-06-01

    Two of nine female opossums (Didelphis virginiana) in a closed breeding colony were submitted for necropsy due to a history of poor reproductive performance in the absence of overt clinical disease. On histologic examination, marked granulomatous to pyogranulomatous pneumonia was identified in these animals. Lung sections were stained with periodic acid-Schiff and Gomori's methenamine silver nitrate. Pulmonary lesions were characterized by large numbers of foamy macrophages within the alveoli and interstitium, prominent subpleural and peribronchiolar aggregates of histiocytes, and a few scattered lymphoid nodules. Numerous fungal organisms were evident within the cytoplasm of macrophages on impregnation of histologic sections with the aforementioned stains. Other inciting agents were not identified. A third opossum lacked pulmonary lesions, but had similar organisms within one auricular sebaceous gland/hair follicle without apparent reaction to the organisms. A fungal agent was associated with granulomatous pneumonia in the opossum, and comparison was made with endogenous lipid pneumonia previously described in opossums. These findings stress the importance of use of special stains and additional diagnostic techniques when prominent alveolar macrophage accumulation is present on histologic examination of the opossum lung.

    2005-01-01

    Full Text Available Francisella philomiragia is a rare and opportunistic pathogen capable of producing invasive infection in patients with compromised neutrophil function and in patients that have survived a near-drowning. A case of F philomiragia adenitis and lung nodules, refractory to cephalosporin therapy, is reported in a 10-year-old boy with chronic granulomatous disease following a facial abrasion from a saltwater crab. To the authors' knowledge, this is the first Canadian clinical isolate to be reported. Genus and species identification was confirmed via 16S ribosomal RNA sequence analysis. A literature review revealed three groups at risk of F philomiragia infection: young patients with chronic granulomatous disease; adults with hematogenous malignancy; and near-drowning patients. Pneumonia, fever without an apparent source and sepsis are the main clinical presentations. Invasive procedures may be required to isolate this organism and ensure appropriate antimicrobial therapy. Limited awareness of F philomiragia has led to delayed identification, patient death and misidentification as Francisella tularensis - a biosafety level three pathogen and potential bioterrorism agent.

    Association of dysregulated calcium homeostasis and granulomatous disease is well established. There exist reports in the literature of granulomatous reactions produced by silicones associated with hypercalcemia. In this case series we report four young women that underwent methacrylate injections in gluteus, thighs and calves that developed granulomas with posterior appearance of hypercalcemia. This complication presented as subacute around 6 months after the procedure. The four patients have as common elements the presence of moderate to severe renal insufficiency, suppressed PTH and elevated calcitriol levels for the degree of renal function. In the image studies, two patients presented in the nuclear magnetic resonance of the gluteus hypodense nodular images compatible with granulomas. Two patients had a positron emission tomography performed showing increased metabolic activity in the muscles of the gluteal region compatible with granulomas. Two patients had a partial surgical resection of the gluteal lesions with the finding of methacrylate associated to foreign body granulomas. In these patients hypercalcemia was treated with oral or local injections of corticoids, intravenous bisphosphonates or ketoconazole with good response. Although the prevalence of this complication with methacrylate injection is not common, hypercalcemia secondary to granulomas should be considered in the differential diagnosis of patients with hypercalcemia when there is a history of this procedure, and especially if they have a reduction in their renal function.

    A 5-yr-old, captive, hatched, female false gharial (Tomistoma schlegelii) presented with a 1-mo history of cervical spinal curvature. Antemortem diagnostics, including blood work, electromyography, muscle biopsies, and advanced imaging tests, were either within reference ranges or did not identify any specific etiology. Necropsy revealed extensive, marked, chronic granulomatous encephalomyelitis along with neuronal necrosis, rarefaction, gliosis, and astrocytosis of the white and gray matter of the cerebrum, cerebellum, brainstem, and spinal cord. Pan-chlamydiae polymerase chain reaction protocols for the 16S ribosomal RNA and ompA genes were performed on samples of spinal cord and brain, and both resulted in amplicons. Sequencing of the products revealed that they were positive for a novel Chlamydia species. Infections by members of the phylum Chlamydiae have been reported in a diverse range of vertebrate hosts, including crocodilians. Chlamydia spp. infections are likely underdiagnosed because of a paucity of diagnostic techniques specific for detection. This is the first case report of a novel Chlamydia species associated with severe granulomatous encephalomyelitis in a false gharial.

    Full Text Available The anti-inflammatory and apoptotic activity of the essential oil of Syzygium cumini (L. Skeels, Myrtaceae, leaves was investigated in vivo. The anti-inflammatory action and chronic granulomatous inflammation in BALB/c mice, intravenously infected with Mycobacterium bovis, BCG, (Bacillo Calmet Guerim, was judged by measuring and classifying the granulomas formed in the hepatic parenchyma. The degree of apoptosis in the inflammatory cells was also measured. A reduction in the granulomatous area and a change in the pattern of the granulomas were found. Anti-mycobacterial activity of the essential oil against M. bovis was detected in vitro by an interferometric method in liquid culture medium. The chemical constituents of the essential oil were determined by GC/MS. Higher yields of the essential oil of S. cumini leaves were obtained by extraction in a Clevenger apparatus when the fresh leaves were previously frozen as a pre-processing step. The essential oil obtained from this plant demonstrated a statistically significant and dramatic effect in the chosen model system.

    The simultaneous occurrence of pyoderma gangrenosum (PG) and chronic granulomatous disease (CGD) is uncommon and few cases have been reported worldwide. PG is a rare, chronic, ulcerative, neutrophilic skin disease of unknown etiology that requires immunosuppressive treatment. CGD belongs to Primary Immune Deficiencies in which the main defect lies in an inability of the phagocytic cells to generate superoxide making patients susceptible to serious, potentially life-threatening bacterial and fungal infections. In this manuscript, we present a case of ulcerative pyoderma gangrenosum in a 28-year-old man with recent diagnosis of chronic granulomatous disease during hospitalization for resistant pulmonary tuberculosis complicated with Aspergillus infection. Second-line therapy with dapsone and intravenous immunoglobulin was initially administered but eventually corticosteroids were added to treatment because of disease progression and further ulceration. Patient's ulcers were gradually healed with no side effects. Corticosteroids could be used under close monitoring for the treatment of PG in a patient with CGD, despite the increased risk for infections.

    Children with chronic illnesses are living longer, prompting health care provider attention to the transition from pediatric to adult care. Transition of care is successful when youth are independent in managing their health. The aims of this study were to identify the strengths and barriers to transition from pediatric to adult care and to determine strategies that could enhance the transition process. A survey was administered via a structured interview to 33 young adult participants (19-27 years of age), living with chronic granulomatous disease all of whom transitioned from pediatric to adult care. The participants were predominately male (88%) and Caucasian (73%). Topics covered in the survey included understanding of disease and treatment, adherence, advance care planning, and barriers to transition. Data were analyzed using a conventional content analysis approach. Seventy-six percent of the participants did not understand their disease process and only 50% understood their prophylactic medication regimen. Seventy-five percent of participants perceived their transition as uneventful. Ninety-four percent were independent in self-management skills such as making appointments and 90% in refilling prescriptions. More than half of the participants thought that the transition process needed improvement. Specific suggestions to create a practical approach to transition were offered. Gaps in disease-related knowledge and transition planning were identified by adolescents and young adults living with chronic granulomatous disease. The findings suggest the need for enhancing the transition process utilizing interdisciplinary collaboration to develop a transition policy and program. Published by Elsevier Inc.

    Chronic granulomatous disease is an extremely rare primary immunodeficiency syndrome that can be associated with various oral complications. This can affect high number of patients. However, data on oral complications is sparse. Here we will review the literature and describe the orofacial findings in 12 patients. The age range was 5-31 years. Oral findings were variable, and reflected a low level of oral hygiene. They included periodontitis, rampant caries, gingivitis, aphthous-like ulcers, and geographic tongue. One patient had white patches on the buccal mucosa similar to lichen planus. Another patient had a nodular dorsum of the tongue associated with fissured and geographic tongue. Biopsies from the latter two lesions revealed chronic non-specific mucositis. Panoramic radiographs showed extensive periodontitis in one patient and periapical lesions in another patient. Patients with chronic granulomatous disease may develop oral lesions reflecting susceptibility to infections and inflammation. It is also possible that social and genetic factors may influence the development of this complication. Therefore, oral hygiene must be kept at an optimum level to prevent infections that can be difficult to manage.

    Children's interstitial lung diseases (chILD) are increasingly recognised and contain many lung developmental and genetic disorders not yet identified in adult pneumology. Worldwide, several registers have been established. The Australasian Registry Network for Orphan Lung Disease (ARNOLD) has identified problems in estimating rare disease prevalence; focusing on chILD in immunocompetent patients, a period prevalence of 1.5 cases per million children and a mortality rate of 7% were determined. The chILD-EU register highlighted the workload to be covered per patient included and provided protocols for diagnosis and initial treatment, similar to the United States chILD network. Whereas case reports may be useful for young physicians to practise writing articles, cohorts of patients can catapult progress, as demonstrated by recent studies on persistent tachypnoea of infancy, hypersensitivity pneumonitis in children and interstitial lung disease related to interferonopathies from mutations in transmembrane protein 173. Translational research has linked heterozygous mutations in the ABCA3 transporter to an increased risk of interstitial lung diseases, not only in neonates, but also in older children and adults. For surfactant dysfunction disorders in infancy and early childhood, lung transplantation was reported to be as successful as in adult patients. Mutual potentiation of paediatric and adult pneumologists is mandatory in this rapidly extending field for successful future development.This brief review highlights publications in the field of paediatric interstitial lung disease as reviewed during the Clinical Year in Review session presented at the 2017 European Respiratory Society (ERS) Annual Congress in Milan, Italy.

    Positive results of Laser-Assisted Cancer Immunotherapy (LACI) have been reported previously in the irradiation of superficial tumors. This paper reports the effect of LACI using laser interstitial therapy approach. We hypothesize that the maximum immuno response depends on laser induced tumor temperature. The measurement of tumor temperature is crucial to ensure necrosis by thermal damage and immuno response. Wister Furth female rats in this study were inoculated with 13762 MAT B III rat mammary adinocarcinoma. LACI started seven to ten days following inoculation. Contrary to surface irradation, we applied laser interstitial irradiation of tumor volume to maximize the energy deposition. A diode laser with a wavelength of 805 nm was used for tumor irradiation. The laser energy was delivered inside the tumor through a quartz fiber. Tumor temperature was measured with a micro thermocouple (interstitial), while the tumor surface temperature was controlled with an IR detector. The temperature feedback demonstrates that it is possible to maintain the average tumor temperature at the same level with reasonable accuracy in the desired range from 65°C-85°C. In some experiments we used microwave thermometry to control average temperature in deep tissue for considerable period of time, to cause maximum thermal damage to the tumor. The experimental set-up and the different temperature measurement techniques are reported in detail, including the advantages and disadvantages for each method.

    Interstitial lung diseases limit daily activities, impair quality of life and result in (exertional) dyspnoea. This has mainly been attributed to a decline in lung function and impaired gas exchange. However, the contribution of respiratory muscle dysfunction to these limitations remains to be conclusively investigated. Interstitial lung disease patients and matched controls performed body plethysmography, a standardised 6-min walk test, volitional tests (respiratory drive (P0.1), global maximal inspiratory mouth occlusion pressure (PImax), sniff nasal pressure (SnPna) and inspiratory muscle load) and nonvolitional tests on respiratory muscle function and strength (twitch mouth and transdiaphragmatic pressure during bilateral magnetic phrenic nerve stimulation (TwPmo and TwPdi)). 25 patients and 24 controls were included in the study. PImax and SnPna remained unaltered (both p>0.05), whereas P0.1 and the load on the inspiratory muscles were higher (both prespiratory muscle strength remains preserved. Central respiratory drive and the load imposed on the inspiratory muscles are increased. Whether impaired respiratory muscle function impacts morbidity and mortality in interstitial lung disease patients needs to be investigated in future studies.

  17. Role of interstitial implantation in gynecological cancer

    1987-01-01

    Recurrent cancer at any site carries a gloomy prognosis. Cancer of the cervix that recurs after radical surgery or curative radiation therapy is a perplexing problem confronting both gynecological and radiation oncologists. In the authors' series, 45% of the patients survived disease-free at 1 year and 10% survived without disease at 5 years or longer following interstitial implantation for recurrent cervical cancer. The optimal utilization of this procedure seems to depend on the site of recurrence, the extent of the disease in the pelvis, and the status of para-aortic node involvement. This retrospective analysis enabled the authors to identify the prognostic factors. The most favorable group benefited by this technique were those who presented with either central recurrence or unilateral, localized pelvic side wall recurrent disease. The least morbidity was noticed in those patients with minimal surgical manipulations at the time of the interstitial implantation. The authors recommended that only a limited and essential surgical procedure should accompany interstitial implantation, since the associated morbidity and mortality is high and survival brief

    Full Text Available Rheumatoid arthritis (RA is a systemic autoimmune rheumatic disease of unknown etiology, characterized by chronic erosive arthritis and extraarticular manifestations. Pulmonary involvement is one of the common extraarticular manifestations of RA and may show itself as bronchial tree lesions, rheumatoid nodules, Caplan's syndrome, and lesions in the pleura or pulmonary interstitium (interstitial lung involvement (ILI. High-resolution computed tomography allows the diagnosis of ILI in RA in nearly 70% of cases although the incidence of ILI may be lower (4 to 30% depending on diagnostic methods and patient selection criteria. There are several histopathological types of ILI, the differential diagnosis of which can be troublesome. Usual interstitial pneumonia (UIP and nonspecific interstitial pneumonia are major types of RA-associated ILI. UIP-pattern ILI has a more severe course than ILI with other histological patterns. The clinical presentation of ILI may be complicated by the likely toxic effect of a number of disease-modifying antirheumatic drugs (DMARDs used to treat RA, such as methotrexate and leflunomide, and biological agents (BAs, tumor necrosis factor-α (TNF-α inhibitors. The pathogenesis of pulmonary involvement in RA and the role of synthetic DMARDs and BAs in the development of ILI call for further investigations.An extraarticular manifestation, such as ILI, affects the choice of treatment policy in patients with RA.The relevance of a study of ILI is beyond question. The paper discusses the state-of-the-art of investigations in this area.

    To define different populations of renal interstitial cells and investigate some aspects of their function, we studied the kidneys of normal rats and rats with hereditary diabetes insipidus (DI, Brattleboro) after experimental manipulations expected to alter the number of interstitial cells. DI rats showed an almost complete loss of interstitial cells in their renal papillae after treatment with a high dose of vasopressin. In spite of the lack of interstitial cells, the animals concentrated their urine to the same extent as vasopressin-treated normal rats, indicating that the renomedullary interstitial cells do not have an important function in concentrating the urine. The interstitial cells returned nearly to normal within 1 week off vasopressin treatment, suggesting a rapid turnover rate of these cells. To further distinguish different populations of interstitial cells, we studied the distribution of class II MHC antigen expression in the kidneys of normal and bone-marrow depleted Wistar rats. Normal rats had abundant class II antigen-positive interstitial cells in the renal cortex and outer medulla, but not in the inner medulla (papilla). Six days after 1000 rad whole body irradiation, the stainable cells were almost completely lost, but electron microscopic morphometry showed a virtually unchanged volume density of interstitial cells in the cortex and outer medulla, as well as the inner medulla. Thus, irradiation abolished the expression of the class II antigen but caused no significant depletion of interstitial cells

  5. Early Identification of Interstitial Cystitis May Avoid Unnecessary Hysterectomy

    2009-01-01

    Background: Interstitial cystitis is a clinical syndrome characterized by symptoms of pelvic pain, urinary urgency and frequency, and nocturia. It can be difficult to accurately identify interstitial cystitis because the symptoms overlap many other common gynecologic and urologic conditions. Patients with undiagnosed interstitial cystitis may undergo unnecessary procedures, including hysterectomy. Methods: A PubMed literature search for articles dating back to 1990 was conducted on the topics of interstitial cystitis and hysterectomy. Further references were identified by cross-referencing the bibliographies in articles of interest. Results: The literature review found that hysterectomy is performed more often in patients with undiagnosed interstitial cystitis than in patients with a confirmed diagnosis. Interstitial cystitis often coexists with conditions like endometriosis, for which hysterectomy is indicated. Many patients subsequently diagnosed with interstitial cystitis continue to experience persistent pelvic pain despite having had a hysterectomy for chronic pelvic pain. Careful history and physical examination can identify the majority of interstitial cystitis cases. Conclusion: Interstitial cystitis should be considered prior to hysterectomy in women who present with pelvic pain or who experience pelvic pain after a hysterectomy. If interstitial cystitis is diagnosed, appropriate therapy may eliminate the need for hysterectomy. PMID:19793476

    A 28-year-old woman with systemic lupus erythematosus was referred to our hospital due to nephrotic-level proteinuria despite approximately 1 year of treatment with 50 to 60 mg/d of prednisolone and 100 to 150 mg/d of cyclosporine with methylprednisolone pulse therapy. Kidney biopsy showed diffuse global lupus nephritis (World Health Organization class 4-G A/C) with many intraglomerular foam cells containing cholesterol crystals. Surprisingly, proteinuria diminished after only 5 low-density lipoprotein (LDL) cholesterol apheresis sessions. This case demonstrated the potential of LDL apheresis to exhibit a remarkable effect on not only focal segmental glomerulosclerosis, but also other types of nephritis, particularly nephritis with intraglomerular foam cells.

    Previous studies have documented the high frequency of thrombosis and fetal loss in patients with lupus nephritis and antiphospholipid (aPL) antibodies, but there is little information on the impact of aPL antibodies on the outcome of lupus nephritis. The aims of this study are to evaluate the prevalence of aPL antibodies in patients with lupus nephritis and assess their prognostic value for thrombosis and pregnancy morbidity and impact on long-term renal outcome. One hundred eleven patients with lupus nephritis followed up for a mean of 173 +/- 100 months were tested regularly for immunoglobulin G (IgG) and IgM anticardiolipin antibodies and lupus anticoagulant. The overall prevalence of aPL antibodies was 26%. In follow-up, 79% of aPL antibody-positive patients experienced thrombotic events and/or fetal losses, and aPL antibodies were associated significantly with arterial or venous thrombosis (P = 0.00001), pregnancy morbidity (P = 0.045), thrombocytopenia (P = 0.0015), and persistent arterial hypertension (P = 0.028). aPL antibodies were significantly more frequent in patients with biopsy-proven membranous lupus nephritis (P = 0.01). A strong association between aPL antibodies and the development of chronic renal insufficiency in the long-term outcome also was found (P = 0.01). With multivariate analysis, aPL antibody positivity (P = 0.02), high plasma creatinine level at presentation (P = 0.01), and chronicity index (P = 0.00004) were independent predictors of chronic renal function deterioration. Detection of aPL antibodies in patients with lupus nephritis is useful not only to identify patients at risk for vascular and obstetric manifestations, but also for their potential deleterious impact on renal outcome.

    Anti-pentraxin 3 (PTX3) auto-antibodies were found to be associated with the absence of renal involvement in systemic lupus erythematosus (SLE). This study is to investigate the prevalence of anti-PTX3 auto-antibodies and their clinical significance based on a large Chinese lupus nephritis cohort. One hundred and ninety-six active lupus nephritis patients, 150 SLE patients without clinical renal involvement, and 100 healthy controls were enrolled. Serum anti-PTX3 auto-antibodies and PTX3 levels were screened by enzyme-linked immunosorbent assay (ELISA). The associations between anti-PTX3 auto-antibodies and clinicopathological parameters in lupus nephritis were further analyzed. Anti-PTX3 auto-antibodies were less prevalent in active lupus nephritis patients compared with SLE without renal involvement (19.4% (38/196) versus 40.7% (61/150), p auto-antibodies were negatively correlated with proteinuria in lupus nephritis (r = -.143, p = .047). The levels of proteinuria, serum creatinine, and the prevalence of thrombotic microangiopathy were significantly higher in patients with higher PTX3 levels (≥3.207 ng/ml) and without anti-PTX3 auto-antibodies compared with patients with lower PTX3 levels (auto-antibodies (4.79 (3.39-8.28) versus 3.95 (1.78-7.0), p = .03; 168.84 ± 153.63 versus 101.44 ± 47.36, p = .01; 34.1% (14/41) versus 0% (0/9), p = .04; respectively). Anti-PTX3 auto-antibodies were less prevalent in active lupus nephritis patients compared with SLE without renal involvement and associated with less severe renal damage, especially with the combined evaluation of serum PTX3 levels.

    This course considers the group of bladder and kidney diseases that poses great difficulty in preoperative diagnosis. Transitional cell and hypernephroma look-alikes are the true ''great imitators'' of diseases of the urinary system. The first half of the course examines the pathologic-physiologic underpinnings of granulomatous diseases of the urinary tract. With an understanding of these basic processes, the myriad radiologic manifestations of this group of diseases (tuberculosis, xanthogranulomatous pyelonephritis, malakoplakia, schistosomiasis, and so forth) will become more obvious. The second part of the course examines the radiologic and pathologic manifestations of certain common forms of cystitis (cystitis cystica, cystitis glandularis, Cytoxan cystitis, cystitis emphysematosa) and other benign processes (pheochromocytomas, neurofibromas, fibrous polyps, duplications) that may be confused with their malignant counterparts by the unsuspecting radiologists. Knowledge of these two large groups of disease should allow a more intelligent approach to these often misdiagnosed urinary tract diseases

    Full Text Available Background. Histoplasma capsulatum is the most common endemic mycosis in the United States and is a frequent cause of opportunistic infection in immunodeficient hosts. Histoplasmosis is most often self-limiting and goes unrecognized in the immunocompetent population but can progress to disseminated histoplasmosis in patients with an impaired immune system. Liver involvement as a part of disseminated histoplasmosis which usually originates in the lung is well known. However, extrapulmonary hepatic histoplasmosis as a primary manifestation is extremely rare. Case Presentation. We report a rare case of histoplasmosis that presented as persistent fever and abnormal liver function tests in a 66-year-old female with rheumatoid arthritis, receiving infliximab. Conclusion. Emphasizing histoplasmosis as a major cause of acute granulomatous hepatitis and fever of unknown origin in cell mediated immunodeficient population, this case highlights the need for high index of suspicion and the importance of prompt diagnosis since any delay of treatment can be life threatening in this population.

    2014-12-01

    Full Text Available The formation of granulomas is associated with the resolution of Q fever, a zoonosis due to Coxiella burnetii; however the molecular mechanisms of granuloma formation remain poorly understood. We generated human granulomas with peripheral blood mononuclear cells and beads coated with C. burnetii, using BCG extracts as controls. A microarray analysis showed dramatic changes in gene expression in granuloma cells of which more than 50% were commonly modulated genes in response to C. burnetii and BCG. They included M1-related genes and genes related to chemotaxis. The inhibition of the chemokines, CCL2 and CCL5, directly interfered with granuloma formation. C. burnetii granulomas also expressed a specific transcriptional profile that was essentially enriched in genes associated with type I interferon response. Our results showed that granuloma formation is associated with a core of transcriptional response based on inflammatory genes. The specific granulomatous response to C. burnetii is characterized by the activation of type I interferon pathway.

    Lower back pain is due to multiple etiologies that make diagnosis difficult. Primitive spinal lymphoma is rare and its diagnosis often requires ultrasound-guided biopsy. A 30-year old man hospitalized for inflammatory lumbago evolving within the context of an impaired general condition. Phisical examination revealed pain on palpation of the L2-L3 vertebral apophysis without peripheral tumor syndrome. Laboratory tests showed an inflammatory syndrome. Morphological assessment was in favour of a spondylodiscitis. The first biopsy showed granulomatous osteitis.Clinical and radiological worsening during antibacillary treatment led to reconsider the original diagnosis and a second biopsy confirmed the diagnosis of lymphoma. The diagnosis of skeletal tuberculosis in particular spinal tuberculosis requires bacteriological or histological confirmation in order not to overlook a primitive bone lymphoma.

However, atopic dermatitis affects approximately 10% of infants, and cutaneous infections are not uncommon in children, therefore the challenge for the dermatologist is to distinguish the few patients that have PID from the many that do not. We report on a 6-year-old girl who was ultimately diagnosed with autosomal recessive chronic granulomatous disease (AR-CGD) after presenting to various hospitals with dermatitis, scalp plaques recalcitrant to treatment, and recurrent infections over a 3-year period, and describe some aspects of her diagnosis and management. This report highlights the importance of considering rare disorders such as AR-CGD in the differential diagnosis of recurrent or recalcitrant dermatological infections in children. © The Author(s).

    An unusual variant of dendritic cell neurofibroma is reported. In contrast to previous cases, the formation of pseudorosettes was lacking. The tumor was located on the anterior aspect of the thigh in a previously healthy 71-year-old woman with no evidence of neurofibromatosis. The tumor was composed of type-1 and type-2 cells, which were immunoreactive for S-100 protein and CD57. The granulomatous appearance was due to the zonal accumulation of CD34-positive dendritic cells and type-1 cells in a serpiginous fashion surrounding large areas with lesser cellularity featuring type-2 cells with scattered type-1 cells arranged in a haphazard fashion. Intralesional small neurites positive for neurofilament and perilesional perineural cells positive for epithelial membrane antigen were documented immunohistochemically.

    Ten cases of acquired antibody deficiency syndrome with chronic granulomatous infection were diagnosed in our hospital during the past 10 years. We were able to perform a retrospective analysis of the initial and follow-up chest radiographs in 8 of these patients. The following pathological findings could be demonstrated: 1. increased bronchovascular markings in the basal lung fields, 2. reticular densities in the middle and basal lung fields, 3. confluent nodular densities of varying size in the periphery of the basal and middle fields, 4. pulmonary infiltrates in the middle and lower lobes, 5. hilar node enlargement of moderate extent. Findings 2, 3 and 5 completely disappeared under steroid therapy whereas 1 showed only partial recovery. If both the radiologic and serologic findings are considered, it is possible to differentiate this disease from sarcoidosis. (orig.) [de

    Full Text Available ABSTRACT: This paper reports eleven cases of ulcerative and granulomatous enteritis associated with Molineus torulosus parasitism in different species of neotropical primates of the Sapajus genus. All of the affected monkeys had been apprehended by the environmental police and were being treated in a rehabilitation center for wild animals. The clinical history was weight loss and debility. During the necropsy, several nodules were found on the duodenum and proximal jejunum wall, with ulcers on the adjacent intestinal mucosa, including the nodules in the pancreas of four monkeys. Histologically, eosinophilic granulomas were observed in the small intestine, associated with fibrosis, eggs and adult models of Trichostrongylidae, etiology consistent with Molineus torulosus. This study describes the first cases of parasitism in Sapajus flavius, a species previously considered extinct, but recently rediscovered, and presents the occurrence of M. torulosus in two other species, Sapajus libidinosus and Sapajus apella.

  17. Lupus Nephritis among Arabs - Differences with other Races; Emphasis on Clinicopathological and Serological Perspectives

    Full Text Available Data on ethnic differences of lupus nephritis (LN are extremely scattered in the literature. Furthermore, most of the publications on LN in Arabs have in fact discussed the condition within the general frame of systemic lupus erythematosus (SLE disease in mixed, but Arab-dominated groups of patients, and fewer, in exclusively Arab individuals. Lupus nephritis however, seems to be common, occurring in 37-69% of SLE patients in the Arab dominated groups and in 50% of the exclusively Arab group. In two out of three groups who reported their renal biopsy results, WHO class III was the most common histopathological type (36% and 54% respectively. Interestingly, the relatively high prevalence of nephropathy in the two groups was associated with a low prevalence of discoid lupus. Arabs with LN who have been studied for serological correlation, did not exhibit any specific or distinctive entity of autoantibody profile. Nonetheless, contradictory data have been noticed in relation to dsDNA antibodies, as they significantly correlated with LN in some of the Arab dominated groups, but not in the uniformly Arab group. Anti-RNP antibodies significantly correlated with non-nephritic SLE patients in the latter group, suggesting a possible protective role of these antibodies. The previously reported correlation between anti-Sm antibodies was not confirmed in the Arab groups. Like the other features of SLE, the differences related to LN in various populations are very likely to be multifactorial rather entirely being ethnical. Lupus nephritis in Arabs however, requires further demarcation by evaluating larger number of patients preferably through multicenter studies.

    The discovery of serum biomarkers specific for paediatric lupus nephritis (pLN) will facilitate the non-invasive diagnosis, follow-up and more appropriate use of treatment. The aim of this study was to explore the role of serum high-mobility group box 1 (HMGB1) protein, antibodies against nucleosomes (anti-NCS), complement factor C1q (anti-C1q) and glomerular basement membrane (anti-GBM) in pLN. Serum samples of 42 patients with paediatric systemic lupus erythematosus (pSLE) (22 with pLN and 20 without renal involvement), 15 patients with other autoimmune nephritis (AN) and 26 healthy controls (HCs) were examined using enzyme-linked immunosorbent assay (ELISA). The activity of both pSLE and pLN was assessed by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) tool. The levels of all four biomarkers were significantly higher in pLN compared to AN and to HCs. The anti-NCS, anti-GBM and HMGB1 serum levels were significantly higher in pLN than in pSLE without renal involvement. The anti-C1q and the HMGB1 serum levels were correlated positively with pSLE activity. The HMGB1 serum levels were also correlated positively with pLN activity. These findings suggest that serum anti-NCS, anti-GBM and HMGB1 may serve as biomarkers specific for the presence of nephritis in pSLE. HMGB1 emerged as a useful biomarker for the assessment of pLN and pSLE activity, whereas anti-C1q only of pSLE activity. © 2016 British Society for Immunology.

    Full Text Available Henoch-Schönlein purpura is a type of systemic small vessel vasculitis. The dominant manifestation is the cutaneous component, the illness is self-limiting in nature, and the prognosis and outcome depend mostly on renal manifestations. We analysed the associations among clinical and laboratory parameters with the prognosis and outcome of HSP in children hospitalised at the Paediatrics clinic, Clinical Centre, Kragujevac between January 2011 and January 2012. Children who developed nephritis were older on average and all manifested with arthritis, abdominal complaints, microhaematuria, elevated D-dimer levels in the serum, and significant proteinuria and microalbuminuria (≥ 300 mg/L, and two children had pre-existing allergic conditions. All three children with repeatedly positive proteins in the morning sample urine test had significant proteinuria (≥0,5 g/24 h and microalbuminuria (≥ 300 mg/L. These children had more bursts of rash and more severe and lasting abdominal pain and arthritis compared to children with normal urine tests. They were therefore treated with glucocorticoids and an angiotensin-converting enzyme inhibitor. The glomerular filtration rate measured by determining creatinine clearance was normal in all patients. These patients were diagnosed with Henoch-Schönlein purpura nephritis, and their condition was regularly monitored. Analysis of this group of patients demonstrated that the average age of 8 years and abdominal complaints were indicative of nephritis development.. Because both of these parameters are easily noted at disease onset, we suggest careful monitoring of disease course in these children.

    The urinary protein/creatinine ratio has been used instead of 24-hour proteinuria in Nephrology practice for the follow-up of glomerular diseases, considering the advantages of collection and the low cost. However, there are still doubts as to its applicability both for an isolated evaluation and for the follow-up of patients with lupus nephritis. To evaluate 24-hour proteinuria determinations and random urine samples, performing urinary creatinine correction and urinary protein/creatinine ratio in subjects with lupus nephritis. 24-hour proteinuria and urinary protein/creatinine ratio were determined by conventional methods (automated Pyrogallol for proteinuria and alkaline picrate for creatinine). Seventy-eight urine samples of 41 patients diagnosed with systemic lupus erythematosus, according to the American Rheumatology Association, with lupus nephritis, were analyzed, and a good correlation between 24-hour proteinuria and urinary protein/creatinine ratio (r = 0.9010 and r² = 0.813) was observed. However, a poor correlation between random proteinuria (without creatinine correction) versus 24-hour proteinuria (r = 0.635 and r² = 0.403) or versus urinary protein/creatinine ratio (r = 0.754 and r² = 0.569) was seen. 24-hour proteinuria and urinary protein/creatinine ratio were useful in the follow-up of each case. However, we observed that the absolute values were different, which did not allow the replacement of one for the other during follow-up, especially when this result is used to define the activity of the disease. Based on these results, we suggest a period of intersection from one to the other (two to three determinations by both methods), and the choice of one marker for proteinuria follow-up, if necessary.

  1. Are serum cystatin C levels influenced by steroid doses in lupus nephritis patients?

    Marcus Vinicius Madureira e Silva

    2011-09-01

    Full Text Available INTRODUCTION: Cystatin C is considered a promising test to evaluate glomerular filtration rate, since it has characteristics of an ideal endogenous marker, being similar or even superior to serum creatinine according to some studies. However, it is possible that some factors (as corticotherapy could have an influence on serum cystatin C levels regardless of the glomerular filtration rate. The aim of this study was to investigate if different doses of glucocorticoid could have an influence on serum cystatin C levels in lupus nephritis patients. METHODS: We evaluated 42 patients with lupus nephritis that performed 109 different blood collections; their mean age was 37.7 ± 13.1 years old, and 88% were female; the mean estimated glomerular filtration rate was of 61.9 ± 20.0 mL/min. Patients were divided according to their glucocorticoid dose in two groups: A - high (pulse therapy with methylprednisolone and prednisone > 0.5 mg/kg/d, n = 14 versus B - low doses (prednisone ≤ 0.5 mg/kg/d, n = 28. Serum creatinine levels were used as parameters for renal function comparison. Cystatin C was determined by an in-house methodology, using Luminex system flow citometry. RESULTS: Considering these groups, cystatin C levels were different only in the second visit (p = 0.106. But, when the serum creatinine levels were considered in the same groups, a marginally significant difference among them (p = 0.070 was observed, which suggested that the difference in cystatin C levels between the groups was caused by their respective glomerular filtration rate. There was not any difference between those groups that received or did not receive pulse therapy. CONCLUSION: Although some previous studies have shown that glucocorticoid has an influence on serum cystatin C levels, we have not observed such interference in the lupus nephritis patients submitted to corticotherapy.

    The IFN-regulatory factors IRF1, IRF3, IRF5, and IRF7 modulate processes involved in the pathogenesis of systemic lupus and lupus nephritis, but the contribution of IRF4, which has multiple roles in innate and adaptive immunity, is unknown. To determine a putative pathogenic role of IRF4 in lupus, we crossed Irf4-deficient mice with autoimmune C57BL/6-(Fas)lpr mice. IRF4 deficiency associated with increased activation of antigen-presenting cells in C57BL/6-(Fas)lpr mice, resulting in a massive increase in plasma levels of TNF and IL-12p40, suggesting that IRF4 suppresses cytokine release in these mice. Nevertheless, IRF4 deficiency completely protected these mice from glomerulonephritis and lung disease. The mice were hypogammaglobulinemic and lacked antinuclear and anti-dsDNA autoantibodies, revealing the requirement of IRF4 for the maturation of plasma cells. As a consequence, Irf4-deficient C57BL/6-(Fas)lpr mice neither developed immune complex disease nor glomerular activation of complement. In addition, lack of IRF4 impaired the maturation of Th17 effector T cells and reduced plasma levels of IL-17 and IL-21, which are cytokines known to contribute to autoimmune tissue injury. In summary, IRF4 deficiency enhances systemic inflammation and the activation of antigen-presenting cells but also prevents the maturation of plasma cells and effector T cells. Because these adaptive immune effectors are essential for the evolution of lupus nephritis, we conclude that IRF4 promotes the development of lupus nephritis despite suppressing antigen-presenting cells.

    2013-12-01

    Full Text Available Sarcoidosis, a chronic granulomatous disease of unknown cause, has been linked to several environmental risk factors, among which are some that may favor carbon nanotube formation. Using gene array data, we initially observed that bronchoalveolar lavage (BAL cells from sarcoidosis patients displayed elevated mRNA of the transcription factor, Twist1, among many M1-associated genes compared to healthy controls. Based on this observation we hypothesized that Twist1 mRNA and protein expression might become elevated in alveolar macrophages from animals bearing granulomas induced by carbon nanotube instillation. To address this hypothesis, wild-type and macrophage-specific peroxisome proliferator-activated receptor gamma (PPARγ knock out mice were given oropharyngeal instillation of multiwall carbon nanotubes (MWCNT. BAL cells obtained 60 days later exhibited significantly elevated Twist1 mRNA expression in granuloma-bearing wild-type or PPARγ knock out alveolar macrophages compared to sham controls. Overall, Twist1 expression levels in PPARγ knock out mice were higher than those of wild-type. Concurrently, BAL cells obtained from sarcoidosis patients and healthy controls validated gene array data: qPCR and protein analysis showed significantly elevated Twist1 in sarcoidosis compared to healthy controls. In vitro studies of alveolar macrophages from healthy controls indicated that Twist1 was inducible by classical (M1 macrophage activation stimuli (LPS, TNFα but not by IL-4, an inducer of alternative (M2 macrophage activation. Findings suggest that Twist1 represents a PPARγ-sensitive alveolar macrophage M1 biomarker which is induced by inflammatory granulomatous disease in the MWCNT model and in human sarcoidosis.

    Full Text Available Objective. This study evaluated the cell kinetic and formation of granuloma during chronic inflammation induced by Bacillus Calmette-Guérin (BCG in the skeletal muscle of Piaractus mesopotamicus, as a histopathology model to study innate immunity. Materials and methods. Sixty fish were divided in two groups: BCG-inoculated and non-inoculated fish and the inflammatory response analyzed 3, 7, 14, 21 and 33 days post-inoculation (DPI by histopathology after hematoxylin-eosin and Ziehl-Neelsen staining. Results. 3 DPI of BCG showed a diffuse inflammatory reaction mostly composed by mononuclear cells. The inflammation continued diffuse 7 DPI initiating the cellular organization surrounding the inoculum and have continued at 14 DPI with discrete presence of epithelioid-like type cells with acidophilic cytoplasm and floppy chromatin. Higher cellular organization (21 DPI surrounding the granuloma with intense peripheral mononuclear inflammatory infiltrate and nevertheless, an increase in the number of fibroblasts and macrophage-like cells was observed. The inflammatory process became less diffuse 33 DPI with formation of small amount of granuloma surrounded by the same type of reaction found in bigger granuloma. Both the young and old granuloma presented typical characteristic around the inoculum composed by a layer of epithelioid-like type cells, besides macrophages, some lymphocytes and abundant fibroblasts. Conclusions. This study showed the feasibility in the use of pacus to study chronic granulomatous inflammatory response induced by BCG, characterized by changes in the kinetics of inflammatory cells in skeletal muscle classifying as immune-epithelioid type, similar to granulomatous inflammation caused by M. marinum in teleost fish.

    Full Text Available The present study aimed to describe and characterize the cellular components during the evolution of chronic granulomatous inflammation in the teleost fish pacus (P. mesopotamicus induced by Bacillus Calmette-Guerin (BCG, using S-100, iNOS and cytokeratin antibodies. 50 fish (120±5.0 g were anesthetized and 45 inoculated with 20 μL (40 mg/mL (2.0 x 10(6 CFU/mg and five inoculated with saline (0,65% into muscle tissue in the laterodorsal region. To evaluate the inflammatory process, nine fish inoculated with BCG and one control were sampled in five periods: 3rd, 7th, 14th, 21st and 33rd days post-inoculation (DPI. Immunohistochemical examination showed that the marking with anti-S-100 protein and anti-iNOS antibodies was weak, with a diffuse pattern, between the third and seventh DPI. From the 14th to the 33rd day, the marking became stronger and marked the cytoplasm of the macrophages. Positivity for cytokeratin was initially observed in the 14th DPI, and the stronger immunostaining in the 33rd day, period in which the epithelioid cells were more evident and the granuloma was fully formed. Also after the 14th day, a certain degree of cellular organization was observed, due to the arrangement of the macrophages around the inoculated material, with little evidence of edema. The arrangement of the macrophages around the inoculum, the fibroblasts, the lymphocytes and, in most cases, the presence of melanomacrophages formed the granuloma and kept the inoculum isolated in the 33rd DPI. The present study suggested that the granulomatous experimental model using teleost fish P. mesopotamicus presented a similar response to those observed in mammals, confirming its importance for studies of chronic inflammatory reaction.

    It has been reported that T helper 17 cells are involved in the pathogenesis of systemic lupus erythematosus, but there is no report on interleukin-17-targeted therapy. We report a case of a 62-year-old female who presented with psoriasis vulgaris and refractory lupus nephritis. Because her conditions were resistant to conventional treatment, and flow cytometry confirmed the proliferation of activated T helper 17 cells in peripheral blood, and examination of a renal biopsy tissue sample confirmed infiltration of numerous interleukin-17-positive lymphocytes to the renal interstitium, administration of the anti-interleukin-17A antibody secukinumab was initiated. After starting secukinumab the clinical and biological features were improved.

    Within nuclear medicine there is a trend towards quantitative analysis. Gallium renal scan has been reported to be useful in monitoring the disease activity of lupus nephritis. However, only visual interpretation using a four-grade scale has been performed in previous studies, and this method is not sensitive enough for follow-up. In this study, we developed a semi-quantitative method for gallium renal scintigraphy to find a potential parameter for the evaluation of lupus nephritis. Forty-eight patients with lupus nephritis underwent renal biopsy to determine World Health Organization classification, activity index (AI) and chronicity index (CI). A delayed 48-h gallium scan was also performed and interpreted by visual and semi-quantitative methods. For semi-quantitative analysis of the gallium uptake in both kidneys, regions of interest (ROIs) were drawn over both kidneys, the right forearm and the adjacent spine. The uptake ratios between these ROIs were calculated and expressed as the ''kidney/spine ratio (K/S ratio)'' or the ''kidney/arm ratio (K/A ratio)''. Spearman's rank correlation test and Mann-Whitney U test were used for statistical analysis. Our data showed a good correlation between the semi-quantitative gallium scan and the results of visual interpretation. K/S ratios showed a better correlation with AI than did K/A ratios. Furthermore, the left K/S ratio displayed a better correlation with AI than did the right K/S ratio. In contrast, CI did not correlate well with the results of semi-quantitative gallium scan. In conclusion, semi-quantitative gallium renal scan is easy to perform and shows a good correlation with the results of visual interpretation and renal biopsy. The left K/S ratio from semi-quantitative renal gallium scintigraphy displays the best correlation with AI and is a useful parameter in evaluating the disease activity in lupus nephritis. (orig.)

    Two children prepared for bone marrow transplantation with total-body irradiation and cyclophosphamide developed hypertension, microscopic hematuria, proteinuria, diminished renal function, and anemia six months after transplantation. Light microscopy of the kidneys revealed mesangial expansion, glomerular capillary wall thickening, and lumenal thrombosis. Electron microscopy demonstrated widening of the subendothelial space due to the deposition of amorphous fluffy material. In one patient, immunofluorescence microscopy revealed glomerular capillary wall deposition of fibrin and immunoglobulins. The clinical and histologic findings support the diagnosis of radiation nephritis. Patients prepared for bone marrow transplantation with total-body irradiation and cyclophosphamide should be followed closely after transplantation for the development of hypertension, proteinuria, and renal insufficiency

    The most important smoking-related interstitial lung diseases (ILD) are respiratory bronchiolitis, respiratory bronchiolitis-associated interstitial lung disease, desquamative interstitial pneumonia, and Langerhans' cell histiocytosis. Although traditionally considered to be discrete entities, smoking-related ILDs often coexist, thus accounting for the sometimes complex patterns encountered on high-resolution computed tomography (HRCT). Further studies are needed to elucidate the causative role of smoking in the development of pulmonary fibrosis.

    Interstitial pregnancy is a rare but life-threatening condition. A case of a 28-year-old woman with a partially ruptured interstitial pregnancy treated with operative laparoscopy is presented. A laparoscopic cornual resection and a left salpingectomy were performed uneventfully. Serum beta-human chorionic gonadotrophin concentrations were measured serially at weekly intervals until resolved on day 20 postoperatively. It seems, therefore, that laparoscopic treatment is still an effective option for management even in ruptured interstitial pregnancy, preserving the anatomical integrity of the uterus and future fertility, and that rupture of interstitial ectopic pregnancy is not a contra-indication for laparoscopy.

    An 80 year old patient with known interstitial pneumopathy of unknown etiology was hospitalized because of acute onset and rapid deterioration of dyspnea at rest within days. A foregoing neurologic investigation including CT and EEG because of prior syncopes and cramp attacks had not revealed pathologic findings. Thorax X-ray at admission showed homogenous loss of transparency on the left side, calcified basal plaques on both sides and prominent central pulmonary vessels with jumping caliber. A punctate of the leftsided pleural effusion revealed lymphocytic exsudate, normal pH, low glucose and an elevated LDH. The patient died shortly after a collapse at a bowel visit and pulmonary embolism was suspected in accordance to results from arterial blood gas analysis, ECG and chest X-ray. Neurologic symptoms could be explained by recurrent pulmonary embolism. Pleural plaques together with the punctate suggested a malignant etiology. A mesothelioma was taken into consideration, although there were no anamnestic reports on an exposition to asbestos. Autopsy revealed almost complete central embolism of the left pulmonary artery with acute cor pulmonale thus confirming the clinical suspicion. The embolus showed components of different ages of origin. Besides bronchitic and emphysematous alteration histology of the pulmonary tissue revealed interstitial and septal fibrosis with focal tissue consolidation. In one giant cell a typical asbestos body was found (in 1 out of 10 sections). In spite of missing information on an exposition to asbestos an abnormally high exposition must be taken into consideration because of the finding of an asbestos particle in relation to the amount of tissue studied. Apart from interstitial fibrosis asbestos may also cause consolidation of pulmonary tissue. Histology of plaquelike lesions revealed mesothelioma of fibrous type. This finding supports the suspicion that a major part of the pulmonary lesions was due to exposition to asbestos.

    Aim: Keeping in line with the increasing emphasis on organ preservation, we at the Tata Memorial Hospital have evaluated the role of Ir-192 interstitial implant as regards local control, functional and cosmetic outcome in early as well as locally recurrent carcinoma of the distal penis. Patients and Methods: From October 1988 to December 1996, 23 patients with histopathologically proven cancer of the penis were treated with radical radiation therapy using Ir-192 temporary interstitial implant. Our patients were in the age group of 20 to 60 years. The primary lesions were T1 and 7, T2 in 7 and recurrent in 9 patients. Only 7 patients had palpable groin nodes at presentation, all of which were pathologically negative. The median dose of implant was 50 Gy (range 40 to 60 Gy), using the LDR afterloading system and the Paris system of implant rules for dosimetry. Follow-up ranged from 4 to 117 months (median 24 months). Results: At last follow-up 18 of the 23 patients remained locally controlled with implant alone. Three patients failed only locally, 2 locoregionally and 1 only at the groin. Of the 5 patients who failed locally, 4 were successfully salvaged with partial penectomy and remained controlled when last seen. Local control with implant alone at 8 years was 70% by life table analysis. The patients had excellent functional and cosmetic outcome. We did not record any case of skin or softtissue necrosis. Only 2 patients developed meatal stenosis, both of which were treated endoscopically. Conclusion: Our results lead us to interpret that interstitial brachytherapy with Ir-192 offers excellent local control rates with preservation of organ and function. Penectomy can be reserved as a means for effective salvage. (orig.) [de

  18. Interstitial hydraulic conductivity and interstitial fluid pressure for avascular or poorly vascularized tumors.

    A correct description of the hydraulic conductivity is essential for determining the actual tumor interstitial fluid pressure (TIFP) distribution. Traditionally, it has been assumed that the hydraulic conductivities both in a tumor and normal tissue are constant, and that a tumor has a much larger interstitial hydraulic conductivity than normal tissue. The abrupt transition of the hydraulic conductivity at the tumor surface leads to non-physical results (the hydraulic conductivity and the slope of the TIFP are not continuous at tumor surface). For the sake of simplicity and the need to represent reality, we focus our analysis on avascular or poorly vascularized tumors, which have a necrosis that is mostly in the center and vascularization that is mostly on the periphery. We suggest that there is an intermediary region between the tumor surface and normal tissue. Through this region, the interstitium (including the structure and composition of solid components and interstitial fluid) transitions from tumor to normal tissue. This process also causes the hydraulic conductivity to do the same. We introduce a continuous variation of the hydraulic conductivity, and show that the interstitial hydraulic conductivity in the intermediary region should be monotonically increasing up to the value of hydraulic conductivity in the normal tissue in order for the model to correspond to the actual TIFP distribution. The value of the hydraulic conductivity at the tumor surface should be the lowest in value. Copyright © 2015 Elsevier Ltd. All rights reserved.

    An improved scattering optical model was developed under cylindrical coordinate to simulate the thermal effect of diffusing applicator in laser interstitial thermotherapy (LITT). The thermal damage was calculated by finite element method (FEM) using Pennes bio-heat transfer equation and Arrhenius injury integral formula. The numerical results showed that the scattering can considerably influence the evaluation of the lesion area, and the relationship between application powers or time and resulting tissue thermal damage was nonlinear. Although usually applying relatively low power can avoid tissue charring, rather higher power is recommended because it is indispensable to achieve necessary damage threshold and the therapy time can be shortened.

    Interstitial cystitis, or painful bladder syndrome, can present with lower abdominal pain/discomfort and dyspareunia, and pain in any distribution of lower spinal nerves. Patients with this condition experience some additional symptoms referable to the bladder, such as frequency, urgency, or nocturia. It can occur across all age groups, although the specific additional symptoms can vary in prevalence depending on patient age. It should be considered in patients who have other chronic pain conditions such as fibromyalgia, chronic fatigue, irritable bowel, and vulvodynia. The cause is still largely not understood, although there are several postulated mechanisms. Copyright © 2014 Elsevier Inc. All rights reserved.

    Interstitial cystitis is a diagnosis of exclusion. The definition has expanded over the years to encompass painful bladder syndrome. It is disease state that is often delayed in its diagnosis and difficult to manage. Treatment options include oral and intravesical therapies as well as both minor and major surgical options. Also, a patient can improve symptoms by following self-management recommendations that focus on both diet and stress management. Treatment options should be periodically evaluated with validated questionnaires to insure they are improving the patient's symptoms, and a multidisciplinary approach is best to manage the patient.

    Full Text Available Abstract Pulmonary surfactant is a complex mixture of phospholipids and proteins, which is present in the alveolar lining fluid and is essential for normal lung function. Alterations in surfactant composition have been reported in several interstitial lung diseases (ILDs. Furthermore, a mutation in the surfactant protein C gene that results in complete absence of the protein has been shown to be associated with familial ILD. The role of surfactant in lung disease is therefore drawing increasing attention following the elucidation of the genetic basis underlying its surface expression and the proof of surfactant abnormalities in ILD.

    Full Text Available Knowledge of the signalling pathways involved in various diseases has enabled advances in the understanding of pathophysiological, diagnostic and therapeutic models of several inflammatory and autoimmune diseases. Systemic lupus erythematosus is a widely studied autoimmune disease that can affect multiple organs, with a major impact on morbidity and mortality when it involves the kidneys. Over the past 10 years, interest in the role of the TWEAK/Fn14 signalling pathway in lupus nephritis, as well as other clinical settings, has increased. By reviewing the literature, this article assesses the role of this pathway in lupus nephritis, underlines the importance of TWEAK in urine (uTWEAK as a biomarker of the disease and stresses the favourable results published in the literature from the inhibition of the TWEAK/Fn14 pathway as a therapeutic target in experimental animal models, demonstrating its potential application in other settings. Results of ongoing clinical trials and future research will give us a better understanding of the real benefit of blocking this pathway in the clinical course of several conditions.

    Lupus nephritis is one of the most severe Systemic Lupus Erythematosus features, defining treatment modality and prognosis. Our retrospective study, including 178 patients treated for lupus nephritis during 23 years with mostly cyclophosphamide-based initial regimens followed by azathioprine or mycophenolic acid, demonstrates 84.8% of renal response with 19.2% of flares, 15-year patient survival 78.7% and kidney survival 76.3%, and low damage accrual. Both patient and kidney survival significantly differ for subgroups that achieved complete or partial renal response and nonresponders: patient 15-year survival 95% versus 65% versus 35%; kidney 15-year survival 100% versus 58% versus 0%, respectively. 51% (24 out of 47) of patients evaluated at the end of the study period sustained complete renal response; however, only 9 of them had 0 disease activity according to SELENA SLEDAI scale, while 13 patients had scores 2-4 due to the serological abnormalities only. We conclude that (1) initial treatment with cyclophosphamide followed by azathioprine is effective and can be used in agreement with International Guidelines until the evidence for biological treatments benefits becomes available; (2) complete and even partial renal response have positive prognostic value, and failure to achieve renal response negatively influences kidney and patient survival; (3) the validity of complete renal response in SLE is questioned by the absence of conventional definition of SLE remission.

    Full Text Available Lupus nephritis (LN of juvenile onset often has severe disease presentation. Despite aggressive induction therapy, up to 20% of patients with LN are resistant to initial therapy and up to 44% suffer a renal relapse. However, there is no consensus on an appropriate therapeutic regimen for refractory LN. We report a 13-year-old girl with recurrent LN who was not taking her medications. At age of 11 years, she was diagnosed with LN classified as International Society of Nephrology/Renal Pathology Society (ISN/RPS class IV G (A + V. She was treated with prednisolone and MMF after nine methylprednisolone pulses. Nineteen months later, she was admitted to the hospital with generalized edema. Her symptoms were nephrotic syndrome and acute renal dysfunction. She received three methylprednisolone pulses for 3 days, followed by oral prednisolone and MMF. Twenty-seven days after the three methylprednisolone pulses, her acute renal dysfunction was improved, but the nephrotic syndrome was not improved. A second biopsy showed diffuse lupus nephritis classified as the predominant finding of ISN/RPS class V. We added tacrolimus to the MMF. Four months after adding tacrolimus, the nephrotic syndrome improved. We conclude that adding tacrolimus to the treatment regimen for LN resistant to MMF is effective.

    Henoch-Schönlein purpura (HSP) is one of the most common vasculitides in children. It is manifested by skin purpura, arthritis, abdominal pain, renal involvement, etc. Typically, HSP is considered to be self-limiting, although renal involvement (HSP purpura nephritis, HSPN) is the principal cause of morbidity from this disease. For this reason, it is important to clarify the mechanism of onset and clinical manifestations of HSPN and to ascertain the most appropriate treatment for HSPN. In this article, we review the updated pathophysiology and treatment strategies for HSPN. We searched databases including PubMed, Elsevier and Wanfang for the following key words: Henoch-Schönlein purpura, nephritis, mechanism and treatment, and we selected those publications written in English that we judged to be relevant to the topic of this review. Based on the data present in the literature, we reviewed the following topics: 1) the possible pathogenesis of HSPN: several studies suggest that immunoglobulin A immune complexes deposit in the mesangium and induce renal injury; 2) multiple-drug treatment for HSPN: although there have been few evidence-based treatment strategies for HSPN, several studies have suggested that immunosuppressive drugs and multiple drug combination therapy were effective in ameliorating proteinuria and histological severity. HSPN is a severe disease of childhood. To better understand this disease, detailed investigations into the pathogenesis of HSPN and prospective randomized controlled treatment studies on children with severe HSPN are needed.

    B-cells play a crucial role in the pathogenesis of lupus nephritis. Recently, a separate subset has been discovered characterized by expression of Granzyme B. The aim of this study is to investigate this subset in patients with systemic lupus erythematosus (SLE). Isolated PBMCs of SLE-patients (n=30) and healthy controls (n=21) were in vitro stimulated with CPG, IgG+IgM and IL-21. Patients were sub-grouped in patients with and without biopsy proven lupus nephritis. B-cells were analyzed for intracellular Granzyme B expression by flow cytometry. The strongest stimulus for Granzyme B secretion of B-cells was IgG+IgM in presence of IL-21. SLE-patients had a significant decreased percentage of Granzyme B + B-cells in particular SLE-patients with active disease and with lupus nephritis. The frequency of GrB+ producing B-cells is reduced in SLE patients. This may contribute to an imbalanced B-cell regulation towards effector B-cells which might promote the development of lupus nephritis. Copyright © 2017 Elsevier Inc. All rights reserved.

  15. A dexamethasone prodrug reduces the renal macrophage response and provides enhanced resolution of established murine lupus nephritis.

    Fang Yuan

    Full Text Available We evaluated the ability of a macromolecular prodrug of dexamethasone (P-Dex to treat lupus nephritis in (NZB × NZWF1 mice. We also explored the mechanism underlying the anti-inflammatory effects of this prodrug. P-Dex eliminated albuminuria in most (NZB × NZWF1 mice. Furthermore, P-Dex reduced the incidence of severe nephritis and extended lifespan in these mice. P-Dex treatment also prevented the development of lupus-associated hypertension and vasculitis. Although P-Dex did not reduce serum levels of anti-dsDNA antibodies or glomerular immune complexes, P-Dex reduced macrophage recruitment to the kidney and attenuated tubulointerstitial injury. In contrast to what was observed with free dexamethasone, P-Dex did not induce any deterioration of bone quality. However, P-Dex did lead to reduced peripheral white blood cell counts and adrenal gland atrophy. These results suggest that P-Dex is more effective and less toxic than free dexamethasone for the treatment of lupus nephritis in (NZB × NZWF1 mice. Furthermore, the data suggest that P-Dex may treat nephritis by attenuating the renal inflammatory response to immune complexes, leading to decreased immune cell infiltration and diminished renal inflammation and injury.

    Severe lupus nephritis in the absence of systemic lupus erythematosus (SLE) is a rare condition with an unclear clinical presentation and outcome.We conducted a historical observational study of 12 adult (age >18 years) patients with biopsy-proven severe lupus nephritis or lupus-like nephritis without SLE immunological markers at diagnosis or during follow-up. Excluded were patients with chronic infections with HIV or hepatitis B or C; patients with a bacterial infectious disease; and patients with pure membranous nephropathy. Electron microscopy was retrospectively performed when the material was available. End points were the proportion of patients with a complete response (urine protein to creatinine ratio treatment.The study included 12 patients (66% female) with a median age of 36.5 years. At diagnosis, median creatinine and proteinuria levels were 1.21 mg/dL (range 0.5-11.6) and 7.5 g/day (1.4-26.7), respectively. Six patients had nephrotic syndrome and acute kidney injury. Renal biopsy examinations revealed class III or class IV A/C lupus nephritis in all cases. Electron microscopy was performed on samples from 5 patients. The results showed mesangial and subendothelial dense deposits consistent with LN in 4 cases, and a retrospective diagnosis of pseudo-amyloid fibrillary glomerulonephritis was made in 1 patient.Patients received immunosuppressive therapy consisting of induction therapy followed by maintenance therapy, similar to treatment for severe lupus nephritis. Remission was recorded in 10 patients at 12 months after the initiation of treatment. One patient reached end-stage renal disease. After a median follow-up of 24 months, 2 patients relapsed.Lupus nephritis in the absence of overt SLE is a nosological entity requiring careful etiological investigation, including systematic electron microscopy examination of renal biopsies to rule out fibrillary glomerulonephritis. In this series, most patients presented with severe glomerulonephritis, which

    We report the case of a 20-year-old female who presented to the ER with a 1-week history of worsening abdominal pain and intermittent vaginal bleeding for the previous 5 days. Physical exam was notable for bilateral adnexal tenderness and a closed cervix without motion tenderness or discharge. Laboratory data demonstrated a beta HCG level of 7,787 IU/L, and pelvic ultrasound with transvaginal imaging was subsequently performed. Neither an adnexal mass nor a normal intrauterine pregnancy was demonstrable; however, a focal right fundal 7-cm area of heterogeneous echogenicity was observed. Initial findings were felt indeterminate with considerations including potential degenerating leiomyoma coexistent with a nonvisualized intrauterine pregnancy, ectopic pregnancy, or recent spontaneous abortion versus atypical interstitial ectopic pregnancy. The patient, initially declining further clinical intervention, returned within 24 h with continued pain. A repeat ultrasound demonstrated a relatively static and unchanged appearance with only a minimal concurrent interval increase in beta HCG levels. MRI was performed for further elucidation and demonstrated a heterogeneously hypervascular right fundal interstitial 6-cm mass, which, in the clinical context, was most suspicious for an ectopic pregnancy. Confirmatory laparoscopic cornual wedge resection and salpingectomy was subsequently performed.

    Over the past two decades, there has been lot of interest in the use of liposomes as lipid-based biocompatible carriers for drugs administered by the intravesical route. The lipidic bilayer structure of liposomes facilitates their adherence to the apical membrane surface of luminal cells in the bladder, and their vesicular shape allows them to co-opt the endocytosis machinery for bladder uptake after instillation. Liposomes have been shown to enhance the penetration of both water-soluble and insoluble drugs, toxins, and oligonucleotides across the bladder epithelium. Empty liposomes composed entirely of the endogenous phospholipid, sphingomyelin, could counter mucosal inflammation and promote wound healing in patients suffering from interstitial cystitis. Recent clinical studies have tested multilamellar liposomes composed entirely of sphingomyelin as a novel intravesical therapy for interstitial cystitis. In addition, liposomes have been used as a delivery platform for the instillation of botulinum toxin in overactive bladder patients. The present review discusses the properties of liposomes that are important for their intrinsic therapeutic effect, summarizes the recently completed clinical studies with intravesical liposomes and covers the latest developments in this field. © 2017 The Japanese Urological Association.

  3. The Interstitial Language and Transnational Experience

    Directory of Open Access Journals (Sweden)

    Paolo Bartoloni

    2013-08-01

    Full Text Available In this essay I argue that the idea of inhabiting, and of human individuality as the house of being, are fruitful ideas if located in a space defined by movement, porosity, interstitiality, and in an urban and architectural paradigm which is based on openness and inclusiveness. Transnational experiences and localities can be, to this end, extremely instructive. It is essential to articulate the notion of dwelling within an urban context in which building is the result of complex cultural and social interactions, which are characterised not only by the negotiation of space and materials but also, and more importantly, by a range of symbolic values. The symbolism that I refer to here is the product of mnemonic and emotional experiences marked by time and space, which in the case of the migratory and transnational experiences is arrived at through a delicate negotiation of the past and the present, and the ‘here’ (the current locality and the ‘there’ (the native locality. The dwelling that I speak of is, therefore, a double dwelling divided between the present at-hand and the remembered past, and as such it inhabits a space, which is both interstitial and liminal, simultaneously in and out-of-place.

    The theory of the change of elastic constants by point-defects, in particular by interstitials, is briefly summarized. The typical effects of spring changes in a defect lattice on the elastic data are discussed qualitatively. Numerical results for the change of elastic constants by self-interstitials and vacancies are given and compared with experimental data for Cu and Al

  10. Macrophage Transactivation for Chemokine Production Identified as a Negative Regulator of Granulomatous Inflammation Using Agent-Based Modeling

    Full Text Available Cellular activation in trans by interferons, cytokines, and chemokines is a commonly recognized mechanism to amplify immune effector function and limit pathogen spread. However, an optimal host response also requires that collateral damage associated with inflammation is limited. This may be particularly so in the case of granulomatous inflammation, where an excessive number and/or excessively florid granulomas can have significant pathological consequences. Here, we have combined transcriptomics, agent-based modeling, and in vivo experimental approaches to study constraints on hepatic granuloma formation in a murine model of experimental leishmaniasis. We demonstrate that chemokine production by non-infected Kupffer cells in the Leishmania donovani-infected liver promotes competition with infected KCs for available iNKT cells, ultimately inhibiting the extent of granulomatous inflammation. We propose trans-activation for chemokine production as a novel broadly applicable mechanism that may operate early in infection to limit excessive focal inflammation.

  11. Bilateral Synchronous Granulomatous Orchitis in a Patient with Erectile Disfunction: Clinical and Pathologic Study of the Case

    2013-01-01

    Full Text Available A 50-year-old male patient presented with erectile failure and loss of libido. In the physical examination, there were stone-hard indurations in his bilateral testes. The ultrasonographic study demonstrated multiple hypoechoic areas in the testes and normal epididymis. Since the lesion was presumed as malignancy, bilateral inguinal exploration was performed and intraoperative frozen biopsies were studied and diagnosed as inflammatory process. Nevertheless, we decided to perform left orchiectomy to a deeper histopathologic analysis which revealed granulomatous orchitis, mastocytosis, and severe depletion of Leydig cells at the testicular interstitium. Differential diagnosis between testicular tumor and granulomatous orchitis is very difficult in any examination except by histological findings. Bilateral cases of this pathology are relatively rare, but it is necessary to distinguish them from the testicular tumor before surgical intervention to avoid an unnecessary orchiectomy.

    Chronic granulomatous disease is a group of syndromes which share a defect in a component of the phagocyte NADPH-oxidase complex. Without this enzyme activity, phagocytic cells cannot produce superoxide, peroxide, and other potent microbicidal radicals, and are less able to kill ingested pathogens. The clinical picture is characterised by recurrent life-threatening bacterial and fungal infections and abnormal tissue granuloma formation. On the other hand, amyloidosis is a systemic disease with renal involvement occurring in the majority of cases. Recurrent amyloidosis is a rare but well documented event in renal transplant recipients. However, graft loss secondary to amyloidosis has been noted infrequently. In addition, de novo amyloidosis has not been previously associated with graft loss. We report here a renal transplant recipient with chronic granulomatous disease and history of recurrent urinary tract infections, who developed nephrotic syndrome and progressive renal insufficiency secondary to de novo AA amyloidosis leading to graft loss 66 months after transplantation.

  13. Chronic granulomatous disease, the McLeod phenotype and the contiguous gene deletion syndrome-a review

    Full Text Available Abstract Chronic Granulomatous Disease (CGD, a disorder of the NADPH oxidase system, results in phagocyte functional defects and subsequent infections with bacterial and fungal pathogens (such as Aspergillus species and Candida albicans. Deletions and missense, frameshift, or nonsense mutations in the gp91phox gene (also termed CYBB, located in the Xp21.1 region of the X chromosome, are associated with the most common form of CGD. When larger X-chromosomal deletions occur, including the XK gene deletion, a so-called "Contiguous Gene Deletion Syndrome" may result. The contiguous gene deletion syndrome is known to associate the Kell phenotype/McLeod syndrome with diseases such as X-linked chronic granulomatous disease, Duchenne muscular dystrophy, and X-linked retinitis pigmentosa. These patients are often complicated and management requires special attention to the various facets of the syndrome.

  14. A case of granulomatous inflammation of the sigmoid colon caused by a fish bone that resembled cancer.

    This case involved a 76-year-old man. Total colonoscopy was performed as a second examination for colorectal cancer because of positive fecal occult blood results, revealing a neoplasm with ulceration in the sigmoid colon. We suspected type-3 colorectal cancer and performed a biopsy, but the biopsy diagnosis showed only an ulcer with active inflammation. Colonoscopic re-examination in a highly advanced medical institution revealed granulomatous inflammation of the sigmoid colon caused by a fish bone, and the fish bone was removed endoscopically. Granulomatous inflammation of the colon caused by a fish bone is very rare, but sometimes needs to be differentiated from cancer. Endoscopic therapy can also be an option, depending on abdominal findings and the penetration status of the fish bone into the large intestinal wall.

  15. Comparative transcriptional profiling of 3 murine models of SLE nephritis reveals both unique and shared regulatory networks.

    Full Text Available To define shared and unique features of SLE nephritis in mouse models of proliferative and glomerulosclerotic renal disease.Perfused kidneys from NZB/W F1, NZW/BXSB and NZM2410 mice were harvested before and after nephritis onset. Affymetrix based gene expression profiles of kidney RNA were analyzed using Genomatix Pathway Systems and Ingenuity Pathway Analysis software. Gene expression patterns were confirmed using real-time PCR.955, 1168 and 755 genes were regulated in the kidneys of nephritic NZB/W F1, NZM2410 and NZW/BXSB mice respectively. 263 genes were regulated concordantly in all three strains reflecting immune cell infiltration, endothelial cell activation, complement activation, cytokine signaling, tissue remodeling and hypoxia. STAT3 was the top associated transcription factor, having a binding site in the gene promoter of 60/263 regulated genes. The two strains with proliferative nephritis shared a macrophage/DC infiltration and activation signature. NZB/W and NZM2410 mice shared a mitochondrial dysfunction signature. Dominant T cell and plasma cell signatures in NZB/W mice reflected lymphoid aggregates; this was the only strain with regulatory T cell infiltrates. NZW/BXSB mice manifested tubular regeneration and NZM2410 mice had the most metabolic stress and manifested loss of nephrin, indicating podocyte loss.These findings identify shared inflammatory mechanisms of SLE nephritis that can be therapeutically targeted. Nevertheless, the heterogeneity of effector mechanisms suggests that individualized therapy might need to be based on biopsy findings. Some common mechanisms are shared with non-immune-mediated renal diseases, suggesting that strategies to prevent tissue hypoxia and remodeling may be useful in SLE nephritis.

    Bacterial infection of Salmonella enterica serotype Typhi is rare in the United States but endemic in many developing countries. Approximately 3-5% of patients become chronic asymptomatic carriers. We describe an atypical presentation of S. enterica serotype Typhi infection in a 10-year-old male, whose cholecystechtomy and bile culture revealed chronic carrier status despite negative stool tests and the absence of gallstones. The gallbladder showed marked thickening of the wall with an intense suppurative granulomatous reaction.

    A fatal case of Churg and Strauss granulomatous angiitis in a 21-yr-old woman is described. Its unusual features included marked personal and familial dysreaction, sudden onset, bronchopulmonitis with distinct eosinophilia and antibiotic- and cortisone-resistant pericarditis, and a terminal picture of generalised septico-pyaemia. The histological findings included necrotising systemic vasculitis with granulomas, some of them extravascular, in various organs. Differential diagnosis and the relation between this form and panarteritis nodosa are discussed.
