Mucormycosis due to Mucorales is reported at large numbers in uncontrolled diabetics across India, but systematic multicenter epidemiological study has not been published yet. The present prospective study was conducted at four major tertiary care centers of India (two in north and two in south India) during 2013-2015 to compare the epidemiology, treatment strategies and outcome of mucormycosis between the two regions. Molecular techniques were employed to confirm the identity of the isolates or to identify the agent in biopsy samples. A total of 388 proven/probable mucormycosis cases were reported during the study period with overall mortality at 46.7%. Uncontrolled diabetes (n = 172, 56.8%) and trauma (n = 31, 10.2%) were the common risk factors. Overall, Rhizopus arrhizus (n = 124, 51.9%) was the predominant agent identified, followed by Rhizopus microsporus (n = 30, 12.6%), Apophysomyces variabilis (n = 22, 9.2%) and Rhizopus homothallicus (n = 6, 2.5%). On multivariate analysis, the mortality was significantly associated with gastrointestinal (OR: 18.70, P = .005) and pulmonary infections (OR: 3.03, P = .015). While comparing the two regions, majority (82.7%) cases were recorded from north India; uncontrolled diabetes (n = 157, P = .0001) and post-tubercular mucormycosis (n = 21, P = .006) were significantly associated with north Indian cases. No significant difference was noted among the species of Mucorales identified and treatment strategies between the two regions. The mortality rate was significantly higher in north Indian patients (50.5%) compared to 32.1% in south India (P = .016). The study highlights higher number of mucormycosis cases in uncontrolled diabetics of north India and emergence of R. microsporus and R. homothallicus across India causing the disease.
Tropical pyomyositis, a disease often seen in tropical countries, is characterised by suppuration within skeletal muscles, manifesting as single or multiple abscesses. The most common organism implicated is Staphylococcus aureus. In 20%–50% of cases there is a history of trauma to the affected muscles. Commonly involved muscles are quadriceps, glutei, pectoralis major, serratus anterior, biceps, iliopsoas, gastrocnemius, abdominal and spinal muscles. Early diagnosis is often missed because of lack of specific signs, unfamiliarity with the disease, atypical manifestations, and a wide range of differential diagnosis. Diagnostic techniques like ultrasound and computed tomography/magnetic resonance imaging are very useful in diagnosis. The diagnosis is confirmed either by biopsy or aspiration of pus from the affected muscles. The initial antibiotic of choice is cloxacillin. Incision and drainage are important components of management. Treatment for Gram negative or anaerobic organisms should be instituted, whenever indicated. Physicians should become more familiar with this potentially life threatening but curable infective disease entity.
Zygomycosis is a threat in uncontrolled diabetes. New risk factors such as renal failure and chronic liver disease require attention. A elegans is an emerging agent in India. The need for surgical debridement in addition to medical treatment is emphasised. GCS is an independent marker of prognosis in cases of invasive zygomycosis.
Renal involvement in 204 cases with multiple myeloma admitted over a 10-year period to this tertiary care center in north India was retrospectively examined. Renal involvement occurred in 55 cases (27%); the vast majority of whom (94.5%) had presented with renal failure and 7.3% had nephrotic syndrome. The diagnosis of multiple myeloma was made after admission in 51 of the 55 (92.7%) cases. Oliguria was seen in 23.6% and two-third patients required dialysis. Factors precipitating renal failure were identified in 53% and included dehydration (33%), hypercalcemia (24%), nephrotoxic drugs (16%), sepsis (9%), recent surgery (5%) and contrast media (2%), Severe anemia, hypercalcemia, Bence Jones proteinuria and skeletal abnormalities were more frequent in those with renal involvement. Patients with renal involvement were more likely to have a high tumor burden. The myeloma was of light chain type in 68% of those with renal involvement whereas IgG myeloma was commonest (57%) in those without evidence of renal disease. Renal histology was studied in 27 cases with myeloma cast nephropathy seen in over 60%. Tubulointerstitial nephritis was seen in 14% cases, 11% had amyloidosis, 7% had acute tubular necrosis and 3.6% each had nodular glomerulosclerosis and plasma cell infiltration. In 8 cases (14.6%), renal biopsy provided the first clue to the diagnosis of myeloma. Renal function improved in 33% cases. Only 22% of patients on dialysis survived over 6 months. Median survival in those with renal involvement was only 4 months. Development of unexplained renal failure in an elderly individual with normal sized kidneys, in association with disproportionate anemia even in the absence of skeletal lesions should alert the physician to the diagnosis of multiple myeloma.
Background and AimsAnemia is one of the most common extraintestinal manifestations of celiac disease (CD), with iron deficiency anemia (IDA) being the predominant cause. However, anemia in CD can have varied etiologies, including mixed nutritional deficiency. We aimed to study the prevalence and etiology of anemia in CD in a north Indian population.MethodsIn this prospective observational study, consecutive patients with documented CD between January 2012 and December 2013 were included, and all patients underwent detailed clinical assessment; hematological investigations including iron profile, serum folate, and vitamin B12 levels; and esophageoduodenoscopy with duodenal biopsies for histopathological examination. Prevalence of anemia and different deficiencies were calculated, and a correlation between hematological parameters and histological findings was found.ResultsOf the 103 patients studied, anemia was detected in 96 patients, giving a prevalence of 93.2% with a baseline hemoglobin of 8.94 ± 2.54 g/dL. Overall, iron deficiency was seen in 84 (81.5%) patients, followed by vitamin B12 deficiency in 14 (13.6%) and folate deficiency in 11 (10.7%) patients; 17 (16.5%) patients had anemia due to mixed nutritional deficiencies, and 4 (3.9%) patients had anemia of chronic disease. The mean hemoglobin and median ferritin levels were significantly lower in patients with severe villous atrophy compared to those with mild atrophy.ConclusionAnemia in patients with CD is multifactorial. Even though iron deficiency is the most common cause, other nutrient deficiencies should always be explored.
Primary pyomyositis is infection of the skeletal muscles in the absence of adjacent skin, soft tissue, and bone infection. This study was undertaken to look at the spectrum of clinical presentations, therapeutic interventions, and their outcomes and also to evaluate the association of various risk factors with mortality. This was a retrospective study in which the patients admitted with the diagnosis of primary pyomyositis from January 2000 to June 2007 were included. Their demographic details, clinical and laboratory data, Sequential Organ Failure Assessment (SOFA) score at presentation, treatment instituted, complications encountered, and hospital outcome were recorded. Sixty-seven patients (42 males and 25 females) with a diagnosis of primary pyomyositis were included. Median age at the time of presentation was 37 years (interquartile range = 25-50 years). Common presenting symptoms were myalgias [50 (74.62%)] and fever [49 (73.13%)]. Twenty-six patients had underlying predisposing medical conditions. The commonest muscle group involved was iliopsoas muscles in 31 (46.26%) patients. Methicillin-sensitive Staphylococcus aureus was the commonest organism isolated from the pus. Twenty-eight patients developed sepsis and seven died. On univariate analysis, there was a statistically significant association between higher SOFA score, lower Glasgow coma scale, higher pulse rate, lower blood pressure, raised blood urea, raised serum creatinine, higher serum glutamic pyruvate transaminase, raised total bilirubin at presentation, and development of sepsis during hospital stay with mortality. In our study, the patients were seen almost a decade later than those seen in other studies from the region. Evidence of organ dysfunction at presentation and sepsis was associated with increased mortality.
The reasons for progression and autoimmune cytopenias (AIC) in chronic lymphocytic leukemia (CLL) are not entirely clear, with previous studies suggesting a role for regulatory T-cells (Treg). In this study we prospectively studied Treg (CD3+CD4+CD25highCD127low), interleukin-10 (IL-10) producing Treg and T-helper 17 (Th17) (CD3+CD4+IL-17+) cells in 40 treatment-naive patients with CLL. The percentage of Th17 and not Treg cells was significantly higher in the AIC cohort than in those without AIC (p<0.0001). The Treg:Th17 ratio was skewed in favor of Th17 in the AIC cohort (p=0.02). Th17 cells are responsible for AIC of CLL. Analysis of lymph-node aspirates showed that the percentage of Treg and IL-10 expression in Treg and not Th17 was significantly higher than in peripheral blood (p<0.01). Treg cells play a major role in the microenvironment where disease progression occurs. This shows the importance of maintaining the Treg:Th17 equilibrium, for imbalance leads to CLL progression or AIC.
