Renal extraction and urinary excretion of 125I-labelled beta2-microglobulin was studied in rats. The effect of ischaemic renal injury, experimental pyelonephritis, and unilateral nephrectomy was investigated. The tubular secretion of o-iodohippurate (OIH) was measured for comparison. The urinary excretion was calculated as the ratio between the clearance of protein and the glomerular filtration rate. The glomerular filtration rate was estimated as clearance of polyethylene glycol (PEG 1000). The renal arteriovenous concentration difference was lower for beta2-microglobulin than for PEG 1000 IN ALL THE EXperimental groups. In unilateral renal disease the beta2-microglobulin excretion of the intact kidneys was similar to that of the diseased kidneys. A significant differences was noted only after ischaemic renal injury. The same was found for OIH. After removal of the intact kidneys the excretion of beta2-microglobulin increased about 10-fold in pyelonephritic animals and 2- to 30-fold in animals with ischaemic renal injury. One hour after unilateral nephrectomy in normal animals the ratio increased about 50 per cent. The tubular secretion of OIH did not change noticeably. It is concluded that the glomerular filtration is a main step in the intrarenal catabolism of beta2-microglobin and that its urinary excretion is considerably influenced by a reduction in the functioning kidney mass.

Ceftezole (CTZ) was administered to 20 patients with hematopoietic malignancy complicated with infections. These patients consisted of 7 cases of AML, 2 ALL, 2 AMMoL, 1 APL, 1 blast crisis of CML, 2 HD, and 5 NHL. In 13 cases, sites of infection were determined and causative organisms were identified. In other 7 cases, sites of infection or causative organisms were unknown. In the former 13 cases, pneumonia was demonstrated in 6 patients, tonsillitis in 4 patients, pyelonephritis in 2 patients and sepsis in 1 patient. Klebsiella was separated from 5 patients as the causative organisms, E. coli from 2 patients, E. coli and Pseudomonas aeruginosa from 1 patient, Pseudomonas cepacia from 1 patient, Streptococcus viridans from 2 patients, Proteus from 1 patient and Torulopsis from 1 patient. Gram-negative rods were separated from 10 of the 13 cases (77%) as the causative organisms. CTZ was administered intravenously in dose from 4 g to 16 g per day combined with other antibiotics (AMK, GM, DKB, TOB, SBPC, CBPC, LC, ST). The response rate in 12 cases of acute leukemia and in 7 cases of malignant lymphoma was 58% and 43%, respectively. Infections occurred in 4 patients with less than 100 neutrophil per mm3 did never favorably responded even with CTZ.

Arora SK, Swarnim S, Hemal A, Bidhuri N. Acute lymphoblastic leukemia presenting as nephromegaly in a child: A rare case report. Turk J Pediatr 2019; 61: 97-101. Acute leukemia is the commonest pediatric malignancy with acute lymphoblastic leukemia (ALL) constituting about 75% of all leukemias. ALL commonly presents as fever, bleeding, bone pains, anemia, lymphadenopathy and hepatosplenomegaly. The liver, spleen or lymph nodes are the most common sites of extramedullary involvement in ALL, with renal involvement being relatively uncommon. The usual differential diagnosis of acquired massive bilateral nephromegaly in children includes pyelonephritis, obstructive uropathy, infections such as HIV nephropathy, mucormycosis, glycogen storage diseases, myelofibrosis with extramedullary hematopoiesis, kidney tumors and rarely hematological malignancies like ALL. Here we report a 2 years old child who presented with abdominal distention, low grade fever and constipation. Clinical examination revealed massive bilateral nephromegaly. Preliminary investigations showed severe anemia and slightly elevated WBC counts with presence of reactive changes in lymphocytes along with few atypical cells (9%). Abdominal ultrasonography revealed bilaterally enlarged kidneys which was later confirmed by CT abdomen. He was eventually diagnosed with CALLA positive B cell ALL for which treatment was started in accordance with the International network for cancer treatment and research (INCTR) protocol 02 04. At present, he is on maintenance phase and responding well to the treatment with regression of kidney size to normal on follow up ultrasonogram. Thus, leukemia should be considered in a child presenting with bilateral nephromegaly after exclusion of above mentioned differential diagnosis. Bone marrow aspiration must be done before doing a more invasive investigation like renal biopsy.
