Outcome of parapneumonic empyema.

OBJECTIVE: Empyema thoracis is known to have variable age group affection, causative agents and controversy regarding primary mode of management. To look into current demography, bacteriology and treatment outcome. METHODS: Prospective study made on admitted cases of parapneumonic empyema from July 2001 to June 2003. All cases were treated with chest tube drainage, parenteral antibiotics or thoracotomy in multiloculated or non-improving cases. RESULTS: 0.8% (C.I. 0.6-1.0) of total pediatric admission had empyema, who were more likely to be females (P< 0.05), under-weight (P< 0.05) compared to children admitted for other reasons. Staphylococcus aureus is still the commonest isolate (13.2%). All cases received antibiotics prior to hospitalisation. Majority of cases (90.5%) could be successfully managed with antibiotics and chest tube drainage alone. 9.4% cases needed thoracotomy. 5.8% cases needed salvage thoracotomy following non-improvement with chest tube drainage. Fever remission time and duration of hospital stay were comparable in both groups. Thoracotomy cases required antibiotics for shorter period (P=0.04). Two cases died due to reasons other than mode of management. Radiological and lung function recovery was excellent in most of the cases. CONCLUSION: Chest tube drainage is a safe, efficacious primary method of empyema management.

Severe falciparum malaria.

Falciparum malaria affect all ages with multiple-systemic complications which varies in different age group. We studied 242 children with complicated Falciparum malaria with a median age of 6.5 years to look for occurrence of different complications in younger and older age groups and overall mortality picture. Unarousable coma (40.5%), severe anemia (26.03%), repeated seizures (46.2%) and hepatopathy (32.2%) were commonest complications. Under five children had higher risk of development of cerebral malaria (P<0.01), severe anemia (P<0.05) and seizures (P<0.001); whereas above five children had higher risk of acute renal failure (P<0.05) and malarial hepatopathy (P<0.02). Over all mortality was 9.9%, cerebral malaria being the commonest cause (6.6%). Multi-system involvement was seen in 58.4% cases of death. Children having pulmonary edema, shock and cerebral malaria had high case fatality rate.

Hepatopathy in complicated falciparum malaria: report from eastern India.

A prospective study done in 216 children with complicated falciparum malaria showed hepatopathy in 33.3% of cases with a higher incidence in children aged above five years. Bilirubin and alanine aminotransferase were moderately raised in most cases. No significant association with other common complications and no higher risk of mortality was observed.

The influence of hyperbilirubinaemia on malaria-related mortality: an analysis of 1103 patients.

The influence of hyperbilirubinaemia on malaria-related mortality was explored among 1103 cases of acute, Plasmodium falciparum malaria at a referral hospital in Orissa, India. Most (64.3%) of the subjects investigated had > 1.2 mg bilirubin/dl serum and were therefore considered hyperbilirubinaemic. Compared with the other patients, those with hyperbilirubinaemia were much more likely to have cerebral malaria (24.1% v. 9.4%; P < 0.0001) or acute renal failure (9.5% v. 2.3%; P < 0.0001), but not severe anaemia (5.9% v. 4.3%; P < 0.22). Mortality was 7.9% among the patients with hyperbilirubinaemia (all the deaths being attributable to cerebral malaria, acute renal failure and/or severe anaemia) but only 1% among the non-hyperbilirubinaemics. There were no deaths, however, among the 506 hyperbilirubinaemics who did not have cerebral malaria, acute renal failure or severe anaemia, even among those with high serum concentrations of bilirubin. It therefore appears that, in acute, Plasmodium falciparum malaria, hyperbilirubinaemia is not in itself a severe complication, and only appears linked with mortality when associated with at least one other complication.

A multicentric study with arteether in patients of uncomplicated falciparum malaria.

Two hundred and sixty seven patients of uncomplicated P. falciparum malaria completed study in a multicentric phase III clinical trial of Arteether. Arteether was given intramuscularly in a dose of 150 mg daily for three consecutive days. Each patient was followed upto 28 days of alpha, beta arteether therapy. The cure rate was 97% with fever clearance time between 1-7 days (24-168 hours) and parasite clearance time between 1-3 days (24-72 hours). Parasite reappearance rate was found to be 3% and reported at only three of the centres. Following the treatment no adverse effect was observed on haematological, biochemical and vital clinical parameters.

AIDS in India: recent trends in opportunistic infections.

The first case of AIDS in India was reported in 1986. Subsequently, a surveillance system was developed in 1987. The data from this surveillance activity suggest that the HIV infection has now spread to the general population and to all parts of the country, except Arunachal Pradesh in North-eastern India. With the changing scenario of the AIDS epidemic, a host of opportunistic infections add to the present endemic state of some already existing infections like tuberculosis. This report analyses the AIDS cases in India, reported to the National AIDS Control Organization over the years between 1986 to 1997. A total of 3,551 AIDS cases had been reported till 31st May 1997. Tuberculosis (pulmonary and extrapulmonary) is the major opportunistic infection affecting 62% of the cases followed by candidiasis seen in 57% of the patients. In 1997, of the 390 AIDS cases analysed, tuberculosis (pulmonary and extrapulmonary) accounted for 56.5% of the total cases whereas candidiasis was seen in 61% of the cases. An increasing trend was observed with tuberculosis from 58% in 1986-1992 to 68.5% in 1995. No trend could be established in the case of candidiasis, though, a high prevalence of 66% was seen in the cases between 1986 and 1992. An increase was also observed in cases of PCP, cerebral toxoplasmosis and Kaposi sarcoma. In the AIDS cases, chronic diarrhea (76%), weight loss (87%) and fever (85%) appeared to be the major presenting symptoms. But, of the 390 AIDS cases reported in 1997, only 47% of them were suffering from chronic diarrhea. With increase in the number of AIDS cases, India is burdened with a dual epidemic of HIV/AIDS and tuberculosis. The National AIDS Control Organization in India, is involved in training clinicians and laboratory personnel in the diagnosis and management of the AIDS cases. With better diagnosis of the opportunistic infections, especially diarrhea, in AIDS patients, a better picture will emerge regarding the opportunistic infections which would help clinicians and health planners to tackle the AIDS epidemic in a more effective manner.

Status of Plasmodium falciparum resistance to chloroquine in Orissa.

Orissa is known for its contribution of 15-20% of malaria cases to the national total. Deaths due to malaria in the state are also not uncommon. Proportion of P. falciparum cases have reached to 85%. In the recent years over 0.3 million confirmed malaria cases have been reported each year. Annual consumption of chloroquine in the state is over 170 lakh tablets. A 17 year study on monitoring of choloroquine resistance in P. falciparum in Orissa revealed that out of a total of 1165 tests conducted in vivo, in 12% of the cases RI level of resistance was detected. And 4.4% cases were of RII and 1.9% RIII level. 51% of the sample tested in vitro showed P. falciparum resistance to chloroquine. P. falciparum resistance to chloroquine appears to have been developed by the parasite over the length and breadth of the state. Strengthening of the monitoring of drug resistance in P. falciparum in the state is indicated.

Vascular clogging, mononuclear cell margination, and enhanced vascular permeability in the pathogenesis of human cerebral malaria.

To document histopathologic evidence on the pathogenic mechanism of human cerebral malaria, we used light microscopy to study brain specimens from 23 patients who died of central nervous system involvement with Plasmodium falciparum. Sequestration of parasitized red blood cells (PRBCs) leading to cerebral capillary clogging was seen. In a few specimens, vascular clogging by PRBCs was associated with margination of mononuclear cells. In others, capillaries were virtually empty and lymphocytes and monocytes were seen in apposition (marginated) to the capillary endothelial surface. The endothelial cells appeared plump, hypertrophied, and prominent. The capillary wall appeared thickened by fibrinous material. Massive intercellular brain edema along with extravasated red blood cells, mononuclear cells, and plasmatic fluid was also noticed. In addition to hypoxia induced by PRBC-mediated vascular clogging, marginating mononuclear cells may contribute to the pathogenesis of cerebral malaria. The precise role played by this phenomenon needs further evaluation.

Plasma antioxidants and lipid peroxidation products in falciparum malaria.

To investigate the influence of Plasmodium falciparum malaria on plasma antioxidants and lipid peroxidation, plasma ascorbate, urate, total protein and albumin, ceruloplasmin and malondialdehyde (MDA) were determined in two groups of 42 patients each, one with mild and the other with severe falciparum malaria, and in an equal number of age- and sex-matched control subjects. Plasma MDA was found to be significantly higher in malaria patients, and the increase was proportional to the severity of the disease. Of the antioxidants, ascorbate and albumin decreased with severity of disease while urate and ceruloplasmin increased. Only ascorbate correlated inversely with MDA both in mild (r = -0.341, P < 0.05) and severe malaria (r = 0.545, P < 0.01). While plasma albumin correlated inversely (r = -0.442, P < 0.01), urate and ceruloplasmin correlated directly (r = 0.419, P < 0.01 and r = 0.349, P < 0.05, respectively) only in patients with severe malaria. These antioxidants also correlated well with markers of disease severity, indicating the influence of disease severity in regulating their levels in plasma. The presence of significant quantities of ascorbate and albumin, along with increases in some of the other antioxidants and MDA, indicates ineffectiveness of the antioxidant defense system in controlling plasma lipid peroxide content. Increased amounts of thiobarbituric acid-reactive material could have been the result of spillover from increased tissue peroxidation or the presence of pro-oxidants in malarial plasma.

Altered plasma lipid pattern in falciparum malaria.

Plasma levels of HDL, LDL, total cholesterol and triglycerides were measured in 60 patients with falciparum malaria (37 severe cases and 23 mild) and in 83 healthy individuals, to study malaria-induced changes in plasma lipids. Triglyceride levels were lower in the patients than in the controls but the difference was significant only for those with severe malaria (P < 0.001). In contrast, the levels of all the other plasma lipids were significantly higher (P < 0.001) in those with severe malaria than in those with mild malaria, and in the mild malaria cases compared with the controls. Initially LDL cholesterol was estimated by the Friedwald formula, but this gave negative values in a few cases of severe malaria. Plasma lipoproteins were therefore also measured by nephelometry; the estimated levels of S particles, corresponding to LDL, were then found to be lower in all malaria cases than in the controls (P < 0.001) but never negative. Interestingly, levels of L particles in the patients with severe malaria were significantly elevated compared with the other patients and controls (P < 0.001), indicating impaired metabolism of chylomicrons. Plasma albumin, considered a negative acute phase protein (i.e. its level decreases as a consequence of the acute phase response), was reduced significantly and was directly correlated to HDL cholesterol levels (r = 0.715 and r = 0.895, respectively) in both mild and severe malaria. Follow-up of 22 of the severe malaria cases three weeks after treatment indicated that, while triglycerides had returned to similar levels to those in the controls, total cholesterol levels were still elevated and could give misleading results if lipid profiles were used, immediately after malaria infection, to assess an individual's risk of developing atherosclerosis.

Hepatic changes in P. falciparum malaria.

Liver function tests were performed in 165 hospitalized patients suffering from P. falciparum malaria with complications. Serum bilirubin was found increased in 33 patients, and 22 of them had unconjugated hyperbilirubinaemia. Serum alanine aminotransferase was increased in 5 patients, but only to mild to moderate levels. Serum alkaline phosphatase was increased in 11 patients, gamma-glutamyl transpeptidase in 3 patients. Serum total protein and albumin were significantly decreased but these were considered more as indicator of acute phase response. Liver cell necrosis was observed in one patient, and oedema and mononuclear cell infiltration in two patients. Though hepatomegaly and mild elevation of enzymes can be observed in a significant proportion of patients, involvement of liver leading to acute hepatitis or liver cell necrosis is a relatively uncommon complication in P. falciparum malaria.

Influence of serum albumin & total protein on fructosamine measurement.

To assess the effect of serum albumin and total protein on the fructosamine level 57 hypoalbuminaemic patients (serum albumin less than 30 g/1), of whom 44 were nondiabetics and 13 were diabetics, were studied. Fructosamine levels of hypoalbuminaemic diabetics was increased only marginally in comparison to healthy controls (P greater than 0.05) whereas in 122 other normalbuminaemic diabetics, the level was found to be significantly higher (P less than 0.001). In control subjects, the correlation between fructosamine and serum albumin (r = 0.69, P less than 0.001) was better than that of total protein (r = 0.42, P less than 0.01) whereas in hypoalbuminaemic patients the pattern was reversed (r = 0.51 and 0.59 respectively), indicating substantial contribution by the globulins. A working formula suggesting approximate contribution of each gram of albumin and globulin in healthy subjects was calculated. It is inferred that the use of serum fructosamine for assessment of glycaemic status could be misleading in patients with lower albumin values. Calculating serum fructosamine values from serum albumin alone in these patients is likely to be inaccurate, as it ignores the contribution of globulins which can be substantial in certain disease conditions. A gross idea regarding the glycaemic status can be obtained by comparing actual and calculated values of fructosamine from the formula.
