An unusual case of peritonitis in a 61-year-old patient is reported where culture for bacteria and fungi were negative. Acanthamoeba was isolated and the patient was treated with Ceftazidine, Cefazolin, Levofloxacin, Fluconazole and Rifampicin with regular haemodialytic support. The patient was completely cured of the infection and continuous ambulatory peritoneal dialysis (CAPD) fluid became clear after 2 weeks of treatment. Diagnosis and treatment of Acanthamoeba infections are difficult due to the rarity of the infections, lack of familiarity of most clinicians with disease syndromes, and limitations of therapeutics options. Even an experienced microbiologist can easily mistake the amoebae in ascitic fluid for peritoneal macrophages or lymphocytes.
High prevalence of malnutrition and inflammation in undialyzed patients with chronic renal failure in developing countries: A single center experience from Eastern India

Background. Malnutrition is common in patients with chronic renal failure (CRF), and its prevalence before the initiation of dialysis is poorly characterized in these patients in developing countries. There is a paucity of data on the quantification of malnutrition and inflammation in undialyzed patients of CRF from India. This study analyzed the prevalence and causes of malnutrition in patients with CRF before the initiation of dialysis treatment. Material and Methods. In the present study, assessments of nutritional and inflammatory status were carried out in patients with CRF. Serum albumin, body mass index (BMI), triceps skin fold thickness (TST), mid-arm muscle circumference (MAMC), and subjective global assessment (SGA) scoring were used for assessment of nutritional parameters. Serum C-reactive protein and serum ferritin level were used to assess the inflammatory state of the patient. Results. Two hundred and three (146 male, 57 female) patients with CRF were included in the study from August 2004 to April 2006. Overall, the prevalence of malnutrition was 65% (131/203). The age of malnourished patients (93 male, 38 female) ranged from 11-82, with mean age of 52 ± 12.68 years. The mean serum total protein and albumin were also significantly lower in patients with malnutrition in comparison to non malnourished cases (5.50 ± 0.40 gm/dL vs. 5.74 ± 0.38 gm/dL; p < 0.05, and 3.18 ± 0.58 gm/dL vs. 3.68 ± 0.55 gm/dL; p < 0.05). The C-reactive protein and serum ferritin were significantly elevated in the malnourished group as compared to non-malnourished patients (63% vs. 33%; p < 0.05, and 301.2 ± 127.1 mg/dL vs. 212.7 ± 124.9 mg/dL; p < 0.05). Conclusion. Thus, malnutrition was common in patients with CRF before the commencement of dialysis. These data indicate that an emphasis should be placed on the assessment and prevention or correction of malnutrition in patients with CRF because of its documented adverse effect on the outcome on maintenance dialysis.

Multiple myeloma - Presenting as acute kidney injury
(2009) J. Prakash; S.S. Niwas; A. Parekh; Rubina Vohra; I.A. Wani; N. Sharma; Usha
Background : Multiple myeloma (MM) is a commonly encountered hematological malignancy with significant renal involvement and often presents as renal failure. The aim of the present study is to analyze clinical spectrum of acute renal failure (ARF) in patients with MM. Material and methods. We analyzed 26(males 24; females 2) patients of multiple myeloma who were referred for evaluation of ARF between July 1994 - June 2007. The referral diagnosis did not include MM in majority 23(88%) of the patients. Multiple myeloma was diagnosed by at least two of the four features; (1) lytic bone lesions, (2) serum or urine monoclonal peak, (3) Bence Jones proteinuria and (4) more than 20%plama cells in marrow aspirate. Results: Multiple myeloma contributes 1.93 % of total ARF cases (26/1342) over a period of thirteen years. Mean age of patients was 59.3 ± 7.4 years. The clinical manifestations of myeloma included; anemia (100%), Bence Jones proteinuria (80%), "M" peak in serum electrophoresis (69%), lytic bone lesions (62%), "M" peak in urine electrophoresis (54%), body pain (58%), plasma cells more than 20% in bone marrow aspirate (38%). Oliguric ARF was seen in 73% patients. The precipitating factors of ARF identified were; hypercalcemia (31%); infection (23%); volume depletion (19%); and NSAIDs in (15%). Dialysis support was needed in 77% of the patients because of severe renal failure at presentation with mean serum creatinine of 9.05±2.84 mg%. Seventeen patients completed chemotherapy, seven last to follow up and two patients died. Ten (38.5%) patients had complete recovery of renal function; three patients had partial recovery and off dialysis and four patients remained dialysis dependent. Remission of myeloma was achieved in nine of seventeen patients treated with chemotherapy. Renal biopsy finding in nine patients revealed-cast nephropathy in (4), amyloidosis in (3), proliferative glomerulonephritis in (1) and cast nephropathy with chronic interstitial nephritis and plasma cell infiltration in one patient. Conclusion: Acute reversible renal failure is a common complication in MM, multiple myeloma should be considered as cause a cause of unexplained ARF in middle aged and elderly patients. © JAPI 2009.
Study on clinico-epidemiological profile of HIV patients in Eastern India
(2006) J. Chakravarty; H. Mehta; A. Parekh; S.V.S. Attili; N.R. Agrawal; S.P. Singh; S. Sundar
In this study, 438 HIV positive patients attending the HIV clinic of Sir Sundar Lal Hospital, IMS, BHU were enrolled. Of these 354 were males (mean CD4 count 179 ± 9.3 cells/μl) and 84 were females (mean CD4 count 323 ± 28.26 cells/μl). The mean age of the study subjects at the time of diagnosis was 32.6 years. Heterosexual contact was the commonest mode of transmission in 352 (80.4%) patients followed by blood transfusion in 2.5%.History suggestive of a risk factor for HIV transmission could not be elicited in 62 (14.1%) patients. Among male patients, 71.5% were migrant workers. Fever (70.6%), weight loss (53.3%), chronic diarrhea (43.9%) and cough (40.3%) were the common presenting symptoms. Out of the 438 patients, 66.4% had opportunistic infections at the time of reporting to the hospital. The most common opportunistic infection was tuberculosis (38.8%) followed by oropharyngeal candidiasis (20.3%) and diarrhea (12.7%). CD4 counts of the patients were significantly inversely correlated with the number of symptoms and the number of opportunistic infections (correlation coefficient were -.289 and -.236 respectively). © JAPI 2006.
