Mesangial IGM in minimal change glomerular disease: a clinicopathological study in a Malaysian population

Looi LM, Wang F, Lam KL, Chua CT

Pathology, 1985 Jan;17(1):41-4.
PMID: 3889788

During a 6 yr period, 105 (69%) of 153 patients in whom a histological diagnosis of minimal change glomerular disease was made had renal biopsy tissue suitable for immunofluorescence examination. Thirty seven (35%) patients showed glomerular mesangial deposits of IgM. All the patients presented with the nephrotic syndrome. We found no significant difference in age and sex prevalence, presentation, response to therapy and glomerular morphology between IgM positive and IgM negative groups. This study suggests that there is no necessity to categorize IgM positive minimal change glomerular disease as a separate entity.

Paraneoplastic relapsing minimal change disease associated with type A thymoma in an elderly patient: A case report and literature review

Ngoh CLY, Goh GHS, Wong WK

Med J Malaysia, 2019 02;74(1):97-98.
PMID: 30846674

Thymoma is a rare mediastinal tumour that can be accompanied by different paraneoplastic syndromes. Here we report a case of Type A thymoma associated with relapsing minimal change disease (MCD). This case highlights: (1) The need to balance rapid prednisolone weaning against risk for relapse in an elderly patient at risk for steroid-induced complications. (2) The addition of calcineurin inhibitor in relapsed thymoma-related MCD, to achieve steroid sparing effects. Resection of the offending tumour and prompt immunosuppressive therapy are critical in getting best renal and overall outcomes in this rare entity.

Minimal Change Disease (MCD) and Focal Segmental Glomerulosclerosis (FSGS) are common causes of nephrotic syndrome. These two conditions are similar in their presentations but differentiated via their histopathological features and responsiveness to corticosteroids. There are ongoing debates whether MCD and FSGS are at the same spectrum of disease rather than separate entities. FSGS has been postulated to be the severe end of the spectrum of MCD. We have reported a case that has primary FSGS after years of poorly controlled MCD, which supports both conditions are the same spectrum of disease.

Wang F, Looi LM, Chua CT

Q. J. Med., 1982;51(203):312-28.
PMID: 7146313

One hundred and forty-eight patients over the age of 12 years seen from July 1972 through December 1980 were accepted for this review of minimal change glomerular disease (MCGD). The diagnosis was based on a typical clinical presentation, and renal biopsy findings. MCGD forms 43.5 per cent of our patients with idiopathic nephrotic syndrome. The patients were predominantly young adults (82 per cent) and the onset of nephrotic syndrome (NS) occurred below the age of 30 years. Most patients had severe oedema and hypoalbuminaemia. Few patients recovered spontaneously. One hundred and thirty patients were given long-term alternate-day steroid (LASt) therapy. Four had cyclophosphamide alone, 21 patients had cyclophosphamide after a trial of LASt. Eighty-four patients (62.7 per cent) were initial responders: 17 of these after cyclophosphamide, 26 (19.4 per cent) were initial non-responders: five cyclophosphamide, 19 were late responders. Nine patients were partial responders, six were non-responders and one went into renal failure. Forty-one patients defaulted, emigrated or were seen only locally at the time of study. Ninety-nine patients were followed for three to 102 months (mean 23 . 3 months). Thirty-seven patients were followed for 36 to 102 months. Relapses were infrequent but occurred as late as 60 months.

Fulltext Safety and Efficacy of Pneumococcal Vaccination in Pediatric Nephrotic Syndrome

Goonewardene ST, Tang C, Tan LT, Chan KG, Lingham P, Lee LH, et al.

PMID: 31456997 DOI: 10.3389/fped.2019.00339

Nephrotic syndrome affects both children and adults. Idiopathic nephrotic syndrome is reported to be one of the most frequent renal pathologies in childhood. Nephrotic children are at high risk for severe pneumococcal infections as one of the life-threatening complications of nephrotic syndrome due to involvement of the immunosuppressive regimen and the acquired immune deficiency induced by nephrotic syndrome including decreased plasma IgG and low complement system components. Aiming to prevent pneumococcal infection is of paramount importance especially in this era of ever-increasing pneumococcal resistance to penicillins and cephalosporins. The pneumococcal vaccines currently available are inactivated vaccines-the two main forms in use are polysaccharide vaccines and conjugated vaccines. However, the data supporting the use of these vaccines and to guide the timing and dosage recommendations is still limited for nephrotic children. Thus, this review discusses the evidences of immunogenicity and safety profile of both vaccinations on nephrotic patients as well as the effect of nephrotic syndrome treatment on vaccine seroresponses.

Thymoma-associated myasthenia gravis and LGI1-encephalitis, with nephrotic syndrome post-thymectomy

Hor JY, Lim TT, Cheng MC, Chia YK, Wong CK, Lim SM, et al.

J Neuroimmunol, 2018 04 15;317:100-102.

Thymoma is associated with a wide spectrum of autoimmune paraneoplastic syndromes, though it is uncommon for multiple paraneoplastic syndromes to be present in a single individual. We report a rare case of an elderly gentleman who was found to have thymoma-associated myasthenia gravis and LGI1-encephalitis with myokymia, who presented with nephrotic syndrome (minimal change glomerulopathy) after thymectomy. The latter two paraneoplastic syndromes had manifested when prednisolone was tapered down to low dose. This case serves to remind neurologists that apart from paraneoplastic neurological manifestations, thymoma may also be associated with renal disease. Nephropathy in myasthenia patients with thymoma should be properly evaluated, as it is treatable with immunotherapy, and it may even occur post-thymectomy.

Fulltext CD80 Insights as Therapeutic Target in the Current and Future Treatment Options of Frequent-Relapse Minimal Change Disease

Teh YM, Lim SK, Jusoh N, Osman K, Mualif SA

Biomed Res Int, 2021;2021:6671552.
PMID: 33506028 DOI: 10.1155/2021/6671552

Minimal change disease (MCD) is the most common cause of idiopathic nephrotic syndrome in children, and it is well known for its multifactorial causes which are the manifestation of the disease. Proteinuria is an early consequence of podocyte injury and a typical sign of kidney disease. Steroid-sensitive patients react well with glucocorticoids, but there is a high chance of multiple relapses. CD80, also known as B7-1, is generally expressed on antigen-presenting cells (APCs) in steroid-sensitive MCD patients. Various glomerular disease models associated with proteinuria demonstrated that the detection of CD80 with the increase of urinary CD80 was strongly associated closely with frequent-relapse MCD patients. The role of CD80 in MCD became controversial because one contradicts finding. This review covers the treatment alternatives for MCD with the insight of CD80 as a potential therapeutic target. The promising effectiveness of CD20 (rituximab) antibody and CD80 inhibitor (abatacept) encourages further investigation of CD80 as a therapeutic target in frequent-relapse MCD patients. Therapeutic-based antibody towards CD80 (galiximab) had never been investigated in MCD or any kidney-related disease; hence, the role of CD80 is still undetermined. A new therapeutic approach towards MCD is essential to provide broader effective treatment options besides the general immunosuppressive agents with gruesome adverse effects.

MyJurnal

During a period of three years (February 1995 --January 1998), 30 biopsies were performed for patients within the paediatric age group in Hospital Universiti Sains Malaysia (HUSM). The majority of these patients (19 cases) had steroid-resistant Nephrotic Syndrome. Other indications were lupus erythematosus (5 cases), acute or chronic glomerulonephritis (5 cases) and infantile nephrotic syndrome (1 case). The biopsy of the 19 cases of steroid-resistant nephrotic syndrome gave the following findings: 10 showed minimal- change nephrotic syndrome, 4 focal segmental glomerulosclerosis, 3 mesangial proliferative glomerulonephritis and one diffuse sclerosing glomerulonephritis while there was insufficient glomeruli for a conclusive diagnosis in one case. The 5 patients with acute/chronic glomerulonephritis showed diffused sclerosing glomerulonephritis. The other 5 patients with lupus nephritis showed mesangial proliferative glomerulonephritis (2) and severe proliferative glomerulonephritis (3). The 5-month-old child with infantile nephrotic syndrome showed mesangial proliferative glomerulonephritis. There were no severe complications noted during or immediately after the procedure. There were 3 cases of gross haematuria, one lasting less than 24 hours and the other two less than

Morphological patterns of glomerular disease in renal biopsies from 1000 Malaysian patients

Prathap K, Looi LM

Ann Acad Med Singap, 1982 Jan;11(1):52-6.
PMID: 7073229

Adequately biopsied renal tissue received in the Department of Pathology, University Hospital, Kuala Lumpur from 1,000 consecutive Malaysian patients during an eleven year period between 1970 and 1981 was reviewed. The youngest patient was 6 days old and the oldest 80 years. Both sexes were equally represented. The majority of the patients were Chinese (71%) with Malays and Indians comprising most of the remainder. Over half the patients (50.4%) presented with the nephrotic syndrome. Other modes of presentation included systemic lupus erythematosus, proteinuria and haematuria separately or in combination and hypertension. Minimal change (25.7%) and proliferative glomerulonephritis (24.8%) were present in about equal numbers and together accounted for over half of the cases (50.5%). Lupus nephritis was the third most common diagnosis (18.4%). In addition, there were patients with focal glomerulonephritis (5.4%), membranous glomerulonephritis (5.5%), Berger's disease (5.8%), amyloidosis (0.6%) and end stage renal disease (4.0%).

Fulltext Ischemic Stroke in a Young Patient with Nephrotic Syndrome and Antiphospholipid Syndrome

Neoh KK, Tang ASN, Looi I, Anita BM

Case Rep Nephrol, 2020;2020:8828864.
PMID: 33294240 DOI: 10.1155/2020/8828864

We report a case of a 21-year-old man with underlying nephrotic syndrome (NS) secondary to minimal change disease, who developed an ischemic stroke with left hemiparesis. He received intravenous thrombolysis followed by a mechanical thrombectomy. After mechanical thrombectomy, he developed acute kidney injury which subsequently required haemodialysis. Further workup revealed that he had concomitant antiphospholipid syndrome (APS) and NS. He was started on vitamin K antagonist anticoagulant. This case report illustrates the importance of workup in identifying causes of ischemic stroke in a young patient.

PMID: 32281597

OBJECTIVES: To explore the epidemiological and histopathological patterns of glomerular diseases in Sabah.
METHODS: A state-wide cross-sectional study was conducted. There were 336 native renal biopsies in 296 eligible patients from 1st January 2013 to 30th June 2016. All patients aged ≥12 years with sufficient sampling (≥8 glomeruli) for histopathological assessment were included. Graft kidney biopsies, protocol-based biopsies and patients with uncertain demographics were excluded. Demographics of patients, clinical data, laboratory parameters prior to biopsy, and histology findings of renal biopsies were collected from local unit database and recorded into a standardised data collection form. Descriptive statistical analyses were employed and factors associated with Lupus nephritis (LN) were explored using logistic regression.
RESULTS: The mean age during biopsy was 34.53 years (Standard Deviation 0.759). Primary glomerulonephritis (PGN) accounted for 42.6% (126) of all native renal biopsies. The commonest cause of PGN was minimal change disease (38.9%, 49) followed by focal segmental glomerulosclerosis (33.3%, 42) and IgA nephropathy (14.3%, 18). LN is the leading cause for secondary glomerulonephritis (SGN) (87.2%, 136). Younger age (Odds Ratio, OR 0.978; 95% Confidence Interval, 95%CI 0.960, 0.996); female gender (OR 17.53; p<0.001); significant proteinuria (OR 132.0; p<0.001); creatinine level at biopsy (OR 11.26; p=0.004); positive antinuclear antibody (ANA) (OR 46.7; p<0.001); and ANA patterns (OR 8.038; p=0.018) were significant in predicting the odds of having LN.
CONCLUSION: This is the first epidemiology study of glomerular diseases in Sabah. The predominance of LN suggests lower threshold for renal biopsy in patients with suspected glomerular disorders. We have identified significant predictors for early detection and treatment of LN.
