Association between pulmonary disease and IgA nephropathy (IgAN) has been previously reported. However, no association has been reported between hypersensitivity pneumonitis (HP) and IgAN. Here, we report about a patient with no particular medical history, who experienced worsening dyspnoea in the course of 1 month, with ground-glass opacity on chest CT and no improvement after antibiotic therapy. The patient was diagnosed as having HP based on the history of antigen exposure, detection of Trichosporon asahii-specific antibodies and bronchoscopy findings. Concomitantly, findings of renal biopsy revealed the IgAN diagnosis. The patient underwent corticosteroid therapy, with good outcomes for both HP and IgAN. This is the first report in the literature to describe summer-type HP complicated with IgAN.

Renal Biopsies

Abstract Background and Aims End December 2016, a renal biopsy network in the Flemish region (Belgium) was founded as a collaboration between the renal pathologists and nephrologists. This FCGG network introduced a uniform renal biopsy request form, a well-structured report form of the renal pathology examination and a comprehensive list of renal pathology diagnoses. Method Following informed consent [99.5%] and in compliance with GDPR, the registration of the renal biopsies consists of basic categorical renal data, structured renal pathology information and the final clinical renal disease. Results In 2017 and 2018, 1385 renal biopsies were registered – 10.5 per million inhabitants per year; in addition, 28 patients had a repeat biopsy in the same time frame (2%). Of the pediatric patients ( age < 18 years; N=92; 6.6%), 23 had IgA nephropathy, 20 a minimal change disease and 15 another type of glomerulonephritis. The biopsy was reported as normal or non-diagnostic in 15 patients (16%) – the majority was clinically considered as glomerulonephritis. The spectrum of the adult population was quite similar across gender and age groups: 56% glomerulonephritis [= IgA nephropathy [19%] + FSGS [8%] + pauci-immune glomerulonephritis [7%] + other GN [22%] ), 10% tubulo-interstitial nephritis, 7% acute tubular necrosis [ATN], 7% diabetes mellitus, and 7% nephroangiosclerosis. Exceptions are pauci-immune glomerulonephritis as the most important renal disease in women aged 65 years and older, and lupus nephritis as the second most important glomerulonephritis in women aged 18-44 years. Only a small percentage of adult renal biopsies yielded no result (7%), clinically interpreted as glomerulonephritis in 50% of the cases. Conclusion The FCGG network has provided a more intense collaboration between renal pathologists and nephrologists mainly by standardizing the renal biopsy reading and reporting across all centers. More precise estimates of the prevalent renal diseases were provided for the first time; however, in order to get full information, renal diseases diagnosed by other techniques ( serology, genetic analysis ) should also be collected in the future. Efforts will be done to coordinate the clinical care of renal diseases, particularly the more rare renal diseases, and to offer access to new therapeutic molecules or new schemes, through this super-regional network.

Abstract Background and Aims Histopathological analysis of renal biopsy is the cornerstone of diagnosis in renal disease and guides treatment and prognosis. The prevalence of various renal diseases varies according to the geographical area, socioeconomic condition, race, age, demography and indication of renal biopsy. Method A retrospective study of all native and transplant kidney biopsies performed at the renal unit of Sri Jayewardenepura General Hospital, Sri Lanka, between 1st October 2012 and 30th September 2019. Samples were processed for light microscopy in all cases, with immunofluorescence in most cases. Results 771 biopsies were analyzed. Majority of biopsies 514 (67%) were male patients. Most biopsies (n= 345, 45%) were in 40 – 59yr age group, followed by 267 (35%) 20–39yr, 117 (15%) 60–69yr, 12 (1%) >70yrs, 30 (4%) 12–19yr age groups. Maximum age was 84 years. In 35 cases, tissue were inadequate. 547 (71%) were native biopsies and 224 (29%) were graft biopsies. Among transplants, majority was for an indication (n=146, 66%) followed by time-zeroes (n=59, 26%) and protocols (n=19, 9%). Rising creatinine (81%) was the strongest reason for transplant biopsies, next proteinuria (10%) and delayed graft function (7%). Time zeroes: majority were normal, few ATN, 1 chronic tubulointerstitial nephritis, and 1 hypertensive glomerulosclerosis. Grafts revealed, acute antibody-mediated rejection 41 (18%) with acute cell-mediated rejection 27 (12%), (total rejections n=68, 30%) followed by normal histology 48 (21%), acute tubular necrosis 43 (19%), chronic allograft nephropathy 23 (10%), BKV nephropathy 5 (2%), and 18% other etiologies: CNI-toxicity (n=4), hypertensive glomerulosclerosis (n=3), diabetic nephropathy (n=2), thrombotic microangiopathy (n=2), FSGS (n=2), MPGN (n=1), vasculitis (n=2), PTLD (n=1), cast nephropathy (n=1), and granulomatous interstitial nephritis (n=1). The most common indication for native biopsy was nephrotic syndrome 209 (38%), followed by non-proteinuric CKD 105 (19%), unexplained renal failure 77 (14%), sub-nephrotic proteinuria 102 (18%), nephritic syndrome 54 (9%). Primary glomerulonephritis (GN) was the commonest 291 (53%). Commonest lesion amidst primary GN was IgA nephropathy 90 (16%), followed by FSGS 63 (12%), CGN 27 (4%), minimal change 36 (6%), MPGN 32 (5%), membranous 6 (1%), DPGN 22 (4%), mesangiocapillary GN 3 (0.5%) and post-streptococcal GN 11 (2%). In the secondary forms of GN, SLE was the commonest 39 (7%), next diabetic nephropathy 29 (5%), amyloidosis 2 (0.3%). Chronic tubulointerstitial nephritis 92 (16%) was the second common, with 42 (7%) CINAC – chronic interstitial nephritis in agricultural communities. Other etiologies: acute tubulointerstitial nephritis 14 (2.5%), hypertensive glomerulosclerosis 12 (2%), thrombotic microangiopathy 6 (1%), ischemic nephropathy 9 (1%), end stage disease 6 (1%), inconclusive 13 (2%). 5 cast nephropathy due to multiple myeloma, 1 monoclonal deposition disease due to lambda chain deposition, 1 sarcoidosis, 1 cholesterol embolism. Conclusion Female: male ratio 1:2 with commonest age group being 40 – 59yrs. Strongest indication for transplant biopsy was rising creatinine. Acute rejection was the most frequent finding in grafts, with normal histology being the next, probably due to high number of time zeroes and protocols performed in our centre. Biopsy proven BKV nephropathy was 2% (n=5). Nephrotic range proteinuria was the commonest native biopsy indication, with non-proteinuric CKD being the second. Primary GN was the commonest finding with IgA nephropathy scoring the highest. This does not coincide with global data, which shows FSGS to be the leading cause. The second common histology was FSGS, and primary CTIN was third. The prevalence of biopsy-proven GN varies due to a wide array of factors and different studies have shown different leading patterns.

Abstract Background and Aims The largest data on the epidemiology of primary glomerular diseases (PGD) are obtained from the databases of countries or centers. Here, we presented the extended results of the Primary Glomerular Diseases Study of the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD)Working Group. Method The data of patients who underwent renal biopsy and diagnosed as primary glomerular disease were recorded in the database prepared for the study. Between May 2009 and May 2019, a total of 4399 patients from 47 centers were evaluated. Basal data of 3875 patients were analyzed after exclusion of those lacking light microscopy and immunofluorescence findings. Results The mean age was 41.5 ± 14.9 years. Of the patients, 1690 were female (43.6%) and 2180 (56.3%) were male. Nephrotic syndrome was the most common biopsy indication (51.7%). This was followed by asymptomatic urinary abnormalities (18.3%) and nephritic syndrome (17.8%). The most common PGH was IgA nephropathy (25.7%), followed by membranous nephropathy (25.6%) and FSGS (21.9%). The mean total number of glomeruli per biopsy was 17 ± 10. Mean baseline systolic blood pressure was 130 ± 20 mmHg and diastolic blood pressure was 81 ± 12 mmHg. Median proteinuria was 3300 (IQR: 1467-6307) mg / day, mean serum creatinine, estimated GFR and albumin values were 1.4 ± 1.5 mg / dl, 80.7 ± 39.1 ml / min and 3.2 ± 0.9 g / dl, respectively. Conclusion In Turkey, the incidence of IgA nephropathy patients have become more common than membranous nephropathy among PGD patients diagnosed with renal biopsy.
