Mesangioproliferative glomerulonephritis (MesPGN) consists 10% of the total renal biopsy of glomerulonephritis. Aim of the present study was to find out clinicopathological changes in MesPGN and differences between diffuse and focal variety. MesPGN was seen mostly in young adults with mean age of 28.63 years for males and 26.3 years for females. Male predominance was noted (M:F ratio - 1.4:1). About 70.83% patient presented with edema feet, followed by hypertension (29.19%), fever (16.66%), oliguria, nausea and vomiting (10.41%). Urine analysis in 50 patients revealed that 70% patients presented with nephrotic-range proteinuria, 36% patients with microscopic hematuria and 56% patients with leukocyturia. Statistically, no significant difference was found in clinical features of diffuse and focal MesPGN. Microscopic comparison between diffuse and focal variety showed that significant increase of focal glomerular basement membrane thickening, focal endothelial cell proliferation, focal smooth muscle hyperplasia, hyaline sclerosis and vasculitis was more common in diffuse variety. In focal variety, Capillary loop congestion, periglomerulitis, cloudy swelling and vacuolar degeneration in tubules were significantly more as compared to diffuse variety. Details of the clinical features, special laboratory tests and histological details revealed that diffuse variety had systemic diseases, which included Wegner's granulomatosis, microscopic polyangitis, Henoch's schonlein purpura, systemic lupus erythematosus (two cases) and one case each of Kimura's disease, pyelonephritis and tuberculosis. Only one case of focal MesPGN showed tuberculosis. Thus, our study concludes that MesPGN is an important cause of nephrotic syndrome among young adults. Secondly, search for some other diseases should be made and thirdly, if biopsy shows focal mesangial cell proliferations in minimal change glomerulonephritis (MCGN), it should be diagnosed as focal MesPGN rather than MCGN because these cases show recurrences.

A 54-year old man was admitted to our hospital because of high fever, productive cough and purpura in both legs in June 2005. Urinalysis showed microscopic hematuria and proteinuria. Chest radiograph showed consolidation of right upper field. Because acid-fast bacilli and polymerase chain reaction test for Mycobacterium tuberculosis were positive in bronchial lavage fluid, we made a diagnosis of pulmonary tuberculosis, and prescribed antituberculosis therapy with isoniazid, rifampicin, ethambutol and pyrazinamide. In addition, anaphylactoid purpura was diagnosed by skin biopsy. In July 2005, renal function was deteriorated and nephrosis appeared. We treated with corticosteroid in addition to antituberculosis therapy. His symptoms and renal dysfunction improved. We report a rare case of an anaphylactoid purpura following occurence of pulmonary tuberculosis.

Few urinary screening studies have been performed to determine the incidence of urinary abnormalities in antiretroviral therapy-naive, HIV-infected outpatients. From published data, the incidence appears to be high, particularly when compared with populations outside sub-Saharan Africa. In South Africa, urinary screening in antiretroviral therapy clinics is not routinely practiced. The aim of this descriptive study was to screen antiretroviral therapy-naive, HIV-infected outpatients attending the HIV clinic for urinary abnormalities, namely leukocyturia, microscopic hematuria, and microalbuminuria/proteinuria. This study showed that 84% of the screened population had AIDS (CD4 count < 200 cells/ mm3), and the incidence of abnormalities on urinary dipstick testing was high: 30% had leukocyturia, 33% had microscopic hematuria, and 44% had microalbuminuria/proteinuria. In patients with leukocyturia, an infective organism was cultured in only 29.1% of cases, predominantly Escherichia coli (70%) with sterile leukocyturia comprising the remainder. There may be an association with tuberculosis (TB) or sexually transmitted infections (STI) in the sterile leucocyturia group, but this remains to be confirmed. In those with a culture positive result the most common organism was E. coli (70%), which exhibited 90% resistance to cotrimoxazole, demonstrating that cotrimoxazole prophylaxis is not effective to prevent urinary tract infection in this group. On the basis of these findings, it has been proposed that urinary screening be considered standard of care in HIV clinics in South Africa. An algorithm has been proposed for use in antiretroviral therapy clinics in South Africa to guide clinicians regarding the cost-effective management of urinary dipstick abnormalities.

A 34-year-old man presented with polymerase chain reaction-positive pleuropulmonary tuberculosis with asymptomatic subnephrotic proteinuria and microscopic haematuria. He was diagnosed to have IgA nephropathy on renal biopsy. The patient was started on a four-drug anti-tuberculous therapy. Healing of the pleuropulmonary lesions along with disappearance of proteinuria and haematuria were seen both at one month and six months post-treatment, with no relapse of renal symptoms at one-year follow-up.

Granulomatous interstitial nephritis (GIN) is an uncommon form of acute interstitial nephritis. We report a young male who presented to us with a rapidly progressing renal failure and massive proteinuria. A renal biopsy revealed GIN, and we were able to demonstrate the presence of tuberculous DNA in the biopsy specimen. The patient was started on anti-tuberculous therapy and steroids besides 11 sessions of hemodialysis. He recovered and is currently doing well. This case highlights an uncommon manifestation of renal tuberculosis, namely massive proteinuria, acute renal failure, and granulomatous interstitial lesions.

Many children in Cape Town are co-infected with human immunodeficiency virus (HIV) and tuberculosis (TB). Granulomatous TB interstitial nephritis is a recognized entity. Our objective was to establish if TB plays a role in renal disease in HIV-infected children. We identified children co-infected with TB and HIV from our database and reviewed their biopsies and clinical notes. Since 2002, 12 renal biopsies or postmortem examinations were performed on HIV-infected children at our institution. The clinical scenario and renal biopsies in four cases (median age 73 months, range 24-108 months) were consistent with TB involvement. The mean CD4 count and percentage of these four patients were 508 cells/microl and 23%, respectively. All four patients presented with culture-proven disseminated TB (not yet on treatment) and had nephrotic range proteinuria and hypoalbuminemia. Three of these patients had renal impairment. The prominent features of the renal biopsies were a severe interstitial inflammatory infiltrate and mild to moderate mesangial proliferation. An interstitial granuloma was seen in one patient. With treatment for the TB, the proteinuria resolved and renal function improved in all four patients. Based on these results, we conclude that TB contributes to proteinuric renal disease in HIV-infected children and that the renal disease improves following TB treatment.

Wegener's granulomatosis usually presents with focal necrotizing glomerulonephritis with crescents. We present here a 45-year old man who was treated for tuberculosis and later presented with bilateral ankle swelling. His serum creatinine was 2.4 mg/dL and urine analysis revealed hematuria and proteinuria. His 24-hour urine protein excretion was 1.9 g. Anti neutrophil cytoplasmic antibodies (ANCA) test was positive with cytoplasmic florescence pattern. Renal biopsy revealed focal segmental sclerosis with no active vasculitis and lung biopsy revealed extensive breakdown with cavitations and scattered granulomas.

Lymphadenopathy is a benign finding in systemic lupus erythematosus (SLE), commonly seen in young patients with cutaneous involvement and constitutional symptoms, with good response to corticosteroids. Reactive follicular hyperplasia is the most frequent finding in biopsies. We report the case of a patient with recurrent episodes of lymphadenopathy associated with hepatosplenomegaly, fever, and weight loss since the age of 13 years. The patient also developed arthritis, hypertension, proteinuria, cardiomyopathy, and peripheral neuropathy. His condition was investigated extensively without diagnostic clarification; he was treated, empirically, for tuberculosis. The patient received a diagnosis of SLE only five years after the original presentation and received the specific treatment. Early diagnosis in those cases is difficult because laboratory exams may not show the presence of auto-antibodies and low complement levels.

Tuberculosis-related chronic granulomatous tubulointerstitial nephritis (GTN) and chronic renal dysfunction as a consequence of GTN is a rarely seen clinical condition, with a few case reports in the literature. In this report, a case with end stage renal failure as an unexpected late extrapulmonary sequela of tuberculosis has been presented. A 60 years old female patient was admitted to hospital with the complaints of fever, malaise and nausea. Her history revealed that she had pulmonary tuberculosis 30 years ago and received antituberculosis therapy for nine months. The laboratory results on admission were as follows: blood urea nitrogen 90 mg/dl, serum creatinine 9 mg/dl, sodium 116 mEq/L, potassium 6.6 mEq/L, albumine 2.9 g/dl, hemoglobin, 8.4 g/dl, white blood cell count 10.800/mm3, C-reactive protein 187 mg/L and erythrocyte sedimentation rate 110 mm/hour. Urinalysis showed 8.1 g/L protein, 10-12 leukocytes, 1-2 erythrocytes, while 24-hours urinalysis yielded proteinuria with 8 ml/minutes creatinine clearance value. Urine and blood cultures of the patient revealed neither bacteria or mycobacteria. PPD skin test was negative. Acid-resistant bacilli (ARB) were not detected in sequential urine samples obtained on three consecutive days. Since sputum samples could not be obtained, diagnostic procedures for sputum were not performed. Abdomen ultrasonography yielded bilateral edema and grade II echogenity in kidneys. Computed tomography of the chest showed bilateral pulmonary nodules, chronic sequela lesions, pleural scarring and calcifications, as well as minimal interstitial infiltrate. Transthoracic lung biopsy showed chronic inflammation and fibrosis, while amyloid was negative. Renal biopsy showed GTN with central caseified necrosis and granulomas, multinuclear giant cells, tubular atrophy and interstitial fibrosis. Amyloid was negative and ARB were not detected in renal biopsy sample. Definitive diagnosis was achieved by the demonstration of Mycobacterium tuberculosis nucleic acid in kidney biopsy by polymerase chain reaction (PCR). Antituberculosis therapy was not initiated since there were no signs of active tuberculosis. The patient became clinically stable following dialysis and was discharged, however, she has been undergoing hemodialysis three times a week. The aim of this case presentation was to emphasize that renal tuberculosis should be considered in the differential diagnosis of patients with end stage renal failure, especially in countries like Turkey where tuberculosis incidence is high.

Membranous glomerulonephritis is rarely associated with tuberculosis infection. We report a case of a 24-year-old female with tuberculous peritonitis associated with membranous glomerulonephritis causing subnephrotic range proteinuria. Histological examination confirmed both diagnoses. The patient showed improvement with anti-tubercular drugs over six months of follow-up.
