    Abstract Introduction: More reports of thrombotic microangiopathy (TMA) in immunoglobulin A (IgA) nephropathy suggest its association with poor clinical outcomes. However, the prevalence and clinical significance of TMA in IgA nephropathy have not been widely studied in different populations.
    Methods: Kidney biopsies of all patients with primary IgA nephropathy from 1995 to 2015 at the King Chulalongkorn Memorial Hospital, Thailand, were retrospectively reviewed and reclassified by two pathologists following the Oxford MEST-C classification. TMA lesions were detected based solely on light microscopic findings. Associations between the presence of TMA and clinical data, other pathologic findings, and clinical outcomes were studied.
    Results: Among 267 patients with primary IgA nephropathy, 166 had adequate clinical data and kidney tissues for the analysis. TMA was observed in 21 patients (13%) and was associated with higher mean arterial pressure (MAP), history of malignant hypertension, higher proteinuria, and lower estimated glomerular filtration rate (eGFR) at diagnosis compared to those without TMA. According to the Oxford MEST-C classification, TMA showed a significant association with severe tubular atrophy/interstitial fibrosis (T2) but not with mesangial hypercellularity (M1), endocapillary hypercellularity (E1), segmental glomerulosclerosis (S1), or crescents (C1-2). After a median follow-up of 50 months, patients with TMA had a significantly higher risk of progression to end-stage kidney disease (ESKD) (hazard ratio [HR] 5.8, 95% confidence interval [CI]: 3.1-10.9) and all-cause mortality (HR 3.4, 95% CI: 1.3-8.8). After adjusting for baseline eGFR, MAP, proteinuria, and other pathological lesions, TMA remained an independent predictor of ESKD (adjusted HR 2.4, 95% CI: 1.1-5.4).
    Conclusions: Kidney TMA in IgA nephropathy is associated with advanced disease stages, carries a poor prognosis, and thus should be considered in the pathological classification of IgA nephropathy.

    Abstract Background: This study aims to investigate the influence of different kidney biopsy practices on the prevalence of glomerular pathologic patterns in the largest kidney biopsy registry in Thailand.
    Methods: We conducted a retrospective review of kidney biopsy records from the period between 2000 and 2014. The records were obtained from 2 major institutions: King Chulalongkorn Memorial Hospital, a large university-based hospital, and the Kidney Center Bangkok Hospital, which provides pathology services to hospitals throughout Thailand. The study included native kidney biopsies from all provinces in Thailand, excluding paediatric patients, kidney transplant recipients, and cases of inadequate and repeated biopsies. Patient demographics, indications for biopsy, and final glomerular diagnoses were compared across different hospital practice settings: university (UVH), private (PVH) and public (PBH).
    Results: A total of 5893 eligible native kidney biopsies were identified from a pool of 7005 biopsies conducted over a 15-year period in 25 provinces throughout Thailand. The 3 most common indications for biopsy were suspected kidney involvement in systemic lupus erythematosus (SLE) (29%), nephrotic syndrome (NS) (29%), and acute glomerulonephritis (AGN)/rapidly progressive glomerulonephritis (RPGN) (13%). The leading indication for biopsy differed across practice types, with suspected kidney involvement in SLE being the primary indication in UVH, while NS took precedence in both PBH and PVH practices. Notably, UVH performed fewer kidney biopsies for asymptomatic urinary abnormalities and diabetes-related indications compared with PVH and PBH. The leading glomerular diagnoses correlated with the biopsy indications, with lupus nephritis (LN) being the most common diagnosis in UVH and PBH practices, whiles immunoglobulin A nephropathy was the predominant diagnosis in PVH practice.
    Conclusion: Hospital practice types significantly impact the prevalence of glomerular pathologic diagnosis patterns in kidney biopsy data, highlighting the importance of considering this influence in epidemiological comparisons.

    Abstract Renal diseases unique to the tropics are those that occur in association with infectious diseases including dengue hemorrhagic fever, typhoid fever, shigellosis, leptospirosis, lepromatous leprosy, malaria, opisthorchiasis, and schistosomiasis. These renal complications can be classified on the basis of their clinical and pathologic characteristics into acute transient reversible glomerulonephritis, chronic progressive irreversible glomerulonephritis, amyloidosis, and acute renal failure (ARF) resulting from acute tubular necrosis, acute tubulointerstitial nephritis, and thrombotic microangiopathy. Certain primary glomerular diseases including immunoglobulin (Ig) M nephropathy and focal segmental and global glomerulosclerosis are prevalent in some tropical countries. Renal complications of venomous snakebites also are common in the tropics. This article discusses and summarizes important works in the literature in respect to the clinical syndromes, pathologic features, and pathogenesis of tropical renal diseases both in humans and experimental animal models.

    Abstract Sera obtained from 5 cases of burn scars (patients group 1) and cases of burn scars with squamous cell carcinoma (patients group 2) of the skin are analysed for anticollagen antibodies. Anticollagen type VI was demonstrable in the serum of one out of 5 cases in group 1 and 4 out of 6 cases in group 2. Collagen type VI was demonstrable in the scar without carcinoma of one patient whose serum contained anticollagen type VI. It is suggested that collagen type VI in the scar and their immunobiologic reaction may be related to the regulation of tumor development in scar tissue of the skin.

    Abstract Antibodies to collagenous and noncollagenous components of glomerular basement membrane (GBM) have been detected by immunoblotting in some sera from patients with various kinds of glomerulonephritis. A half proportion of patients with rapidly progressive glomerulonephritis (RPGN), chronic focal glomerulonephritis (CFGN), idiopathic membranous glomerulonephritis (MGN). IgA nephropathy and lupus nephritis (LE-GN) had IgG antibodies to heterogenous components in acid insoluble fraction of pepsin digested GBM. This acid insoluble fraction represented a complex of collagen and noncollagenous proteins of GBM. Following digestion of acid insoluble fraction with bacterial collagenase, the triple helical collagenous components of GBM were destroyed and released most likely of noncollagenous proteins. Antibodies to this noncollagenous proteins were found in only some patients with chronic glomerulonephritis (17.6%) and lupus nephritis (21.4%). Upon reaction with human placenta derived type IV collagen, different frequencies of antibody response were found in patients of different groups. However, all these reactive sera showed a similar immunoblotting pattern. The relationship between antibody response to antigenic components from human GBM or human placenta and pathogenesis of renal disease is unclear. However, the occurrence of spontaneous autoantibody response to some exposed GBM self antigens may mediate further renal destruction resulting in chronic ongoing stage of the disease.

    Abstract By the indirect immunofluorescent technique, sera from patients with Alport's syndrome showed a reaction with the basement membrane of the capillary wall of glomeruli and peritubular vessels and nearby interstitial tissue of normal monkey and mouse kidney as a substrate. It also revealed bright staining to the matrix surrounding the clusters of EHS tumor cells and stromal tissues. These reactions were caused by autoantibodies present in these sera. These findings were supported by the detection of antilaminin, nidogen and anti collagen type VI in the sera by ELISA method. These evidences suggest that the Alport's patients developed stage of autoimmunity. The exact causes were not so clear, but seemed to be due to multiple factors.

    Abstract Histopathologic and immunopathologic features of cerebral malaria have been defined in a study of six autopsy cases with severe Plasmodium falciparum infection. In five cases, immunofluorescent studies demonstrated intense deposition of P falciparum antigen, IgG, and fibrin in cerebral vessels associated with the histopathologic finding of hemorrhage in the white matter of cerebrum and cerebellum regardless of the presence of parasitized erythrocytes in the cerebral vessels. Immunofluorescent study also demonstrated the extravascular deposits of P falciparum granular antigen associated with acute inflammatory lesion in cerebral tissue in one case. These findings suggested that the immunopathogenic mechanism may in some way play a role in the pathogenesis of cerebral malaria.

    Abstract Sixteen children with extensive crescentic glomerulonephritis and rapid renal deterioration were selected from 476 patients with glomerulopathy for study. The patients (1-14 yr, M:F = 5:11) presented with edema, oligoanuria, hypertension, gross hematuria and uremic symptoms in 81, 62, 62, 56 and 50 per cent, respectively. The mean Scr was 804 (+/- 436) micromole/L and BUN 38 (+/- 13.4) mmole/L. Anemia was found in 100 per cent, hematuria in 100 per cent, heavy proteinuria 75 per cent, hypoalbuminemia 40 per cent, hypercholesterolemia 38 per cent and low C3 40 per cent. The underlying causes of RPGN included idiopathic 9, PSAGN 6 and LE 1. Eight patients recovered with normal or slightly elevated Scr while the diseases progressed to ESRD in 8 patients. Idiopathic RPGN and extensive (greater than 80%) crescentic glomerulonephritis correlated with a poor prognosis.
