Background: Timely diagnosis of invasive fungal infections (IFI) in renal transplant (RT) patients on immunosuppression is often difficult, jeopardizing their life and graft. We reported IFI and their causative fungal agents in post-RT patients.Materials and methods: This was a retrospective 6-year clinical study carried out from 2010 to 2015 on 1900 RT patients. Clinical data included patient-donor demographics, time to onset of infection, risk factors and graft function in terms of serum creatinine (SCr). To identify IFI, we examined bronchoalveolar lavage (BAL), blood, tissue, and wound swab samples by conventional mycological methods.Results: IFI were diagnosed in 30 (1.56%) patients on triple immunosuppression, mainly males (n = 25) with mean age of 36.57 ± 11.9 years at 13.12 ± 18.35 months post-RT. Aspergillus species was identified in 11 BAL, one tissue, and one wound specimen each, 30.76% of these were fatal and 15.38% caused graft loss; Candida albicans was in nine BAL, four blood, two wound swab, and one tissue specimens, 25% of these were fatal and 25% had graft loss and one mucor in BAL which was fatal. Seven patients were diabetic, 10 had superadded cytomegalovirus infection, and 15 were anti-rejected.Conclusion: IFI are associated with increased morbidity and mortality in RT patients. Triple immunosuppression, broad spectrum antibiotics for ≥ two weeks, diabetes and superadded infection are added risks for these patients. Prevention, early diagnosis, and appropriate management are necessary to improve their prognosis.
Background:Renal biopsy is a well-established diagnostic modality for the assessment of kidney diseases in children. It can provide diagnostic precision and prognostic value and guide in therapeutic options for many renal diseases.Objectives:This report describes the indication, histopathological patterns, and epidemiology of renal diseases in children in India.Patients and Methods:This is a single-center study on renal biopsies performed between January 2008 and December 2013 in 346 children (age ≤ 14 years).Results:Eleven (3.17%) biopsies were inadequate, and 335 biopsies were considered for analysis. The mean age was 7.91 ± 3.04 years with a predominance of males (68.1%). Nephrotic syndrome (46.2%) was the most common indication, followed by urinary abnormality (41.19%), acute nephritic syndrome (10.74%), and chronic renal failure (1.79 %). Primary glomerulonephritis (GN) was predominant (81.79%), and secondary GN constituted 16.12% of the biopsies. Primary GN included mesangial proliferative GN (MePGN), IgM nephropathy, focal segmental glomerulosclerosis, minimal change disease, IgA nephropathy, membranoproliferative GN, membranous nephropathy, crescentic GN, and post-infectious GN. Secondary GN revealed lupus nephritis, hemolytic uremic syndrome, amyloidosis, and hypertensive nephropathy. Tubulointerstitial nephritis was observed in 2.08%. The most common histological pattern of primary GN was MePGN (20%) and in secondary GN it was lupus nephritis (7.76%).Conclusions:The present study provides data on the epidemiology of renal diseases in children in India and will be helpful for developing a national registry and devising therapeutic guidelines.
BackgroundGlobally there is an increase in incidence of chronic kidney diseases (CKDs). Diabetes mellitus (DM), hypertension and stone diseases are the major risk factors for CKD. We organized kidney disease screening camps in a semi-urban population of Gujarat, India on the occasion of World Kidney Day (WKD).MethodsVoluntary participants from six towns were screened. Estimated glomerular filtration rate (eGFR) was calculated by the Modification of Diet in Renal Disease formula and CKD was defined as an eGFR <60 mL/min/1.73 m2 or albuminuria ≥1+. Urogenital ultrasonography was performed with emphasis on stone burden. Participants with known diabetes, stone diseases, hypertension, kidney/liver/cardiac disease, hepatitis, HIV, transplant recipients, pregnant women and those <18 years were excluded from the study.ResultsOf the 2350 participants (1438 men), CKD was found in 20.93% and eGFR <60 mL/min/1.73 m2 was noted in 8.29% of participants. The prevalence of CKD peaked after the seventh decade of life in both genders. There was no significant difference in the prevalence of CKD between coastal and non-coastal regions, however, obesity, hypertension and diabetes were more common in the coastal belt, whereas stone burden was greater in the non-coastal region.ConclusionsThe prevalence of CKD in a semi-urban apparently healthy Indian population was higher than the reported prevalence in developed countries. Significant differences between regions point to the need to evaluate and correctregion-specific risk factors.
Diabetic nephropathy (DN) is a major complication of diabetes mellitus (DM), leading to chronic kidney disease/end-stage renal disease. Wide spectrum of nondiabetic renal diseases (NDRD) is reported in type-2 diabetes (type-2 DM). We carried out this single-center study to find clinical, laboratory, and histological features of NDRD in type-2 DM patients and to assess the prevalence of NDRD in India. A single-center retrospective study which included analysis of renal biopsies from patients with type-2 DM, performed between January 2008 and September 2016. Biopsy findings were categorized into three groups, Group-I (isolated NDRD); Group-II (NDRD superimposed on underlying DN); and Group-III (isolated DN). Out of 152 diabetic patients (111 males and 41 females), 35 (23.03%) patients were of Group-I (isolated NDRD), 35 (23.03%) of Group-II (NDRD superimposed on underlying DN), and 82 (53.95%) of Group-III (isolated DN). The mean age (in years) was 55.08 ± 10.71, 55.65 ± 8.71, and 54.45 ± 9.01 respectively in Group-I, II, and III. Nephrotic syndrome (NS) was the most common clinical presentation in all groups. Duration of DM was significantly shorter in Group-I than in Group-II. Diabetic retinopathy was absent in Group-I. Proteinuria was more in Group-III than Group-I. Low serum C3 and/or C4 levels was observed in five (14.29%) cases of Group-I and Group-II each and two (2.43%) cases of Group-III. Nearly, 70 (46.05%) patients were found to have NDRD either in isolated form or as combined lesions. The most common histological types of NDRD were acute tubulointerstitial nephritis (38.57%) followed by benign nephrosclerosis (15.72%), membranous nephropathy (10%), IgA nephropathy (7.14%), and membranoproliferative glomerulonephritis (7.14%). The incidence of NDRD (with/without DN) in type-2 DM is very high. Shorter duration of diabetes, hematuria, absence of retinopathy, low serum complement levels, and nephrotic range proteinuria are predictors of NDRD.
C1q nephropathy (C1qN) is defined by conspicuous C1q deposits in the glomerular mesangial regions of patients who do not have any evidence of systemic lupus erythematosus (SLE). We present our experience with C1qN over the last three years. In total, 1775 native renal biopsies were reviewed and dominant/co-dominant C1q mesangial deposits in patients with absence of clinical and/or serological evidence of SLE were considered as C1qN. Their clinical profile and renal function status were studied and correlated. C1qN was observed in 11 patients (0.61%), and included eight males and three females; the mean age was 36.6 years. The most common presentation was nephrotic syndrome. Hematuria was noted in eight patients (72%). The mean serum creatinine was 2.78 mg/dL. Hypertension was seen in two patients (18%). Mesangial proliferative glomerulonephritis (MePGN) was the most common histological pattern, followed by focal and segmental glomerulosclerosis and other lesions. The common codeposits along with C1q were IgM, followed by C3 and others. MePGN had better prognosis than others. To conclude, C1qN was noted in 0.61% of all renal biopsies with bimodal age distribution and may present as podocytopathy or non-podocytopathy. The prognosis depends on the morphological pattern and C1q deposits per se are not prognostic indicators.
